Anemia design effects in cluster surveys of women and young children in refugee settings
Hulland EN , Leidman E , Wilkinson C , Tondeur M , Bilukha O . PLoS One 2021 16 (7) e0254031 BACKGROUND: Nutrition surveys in many refugee settings routinely estimate anemia prevalence in high-risk population groups. Given the lack of information on anemia design effects (DEFF) observed in surveys in these settings, the goal of this paper is to better understand the magnitude and distribution of DEFFs and intracluster correlation coefficients (ICCs) in order to inform future survey design. METHODS: Two-stage cluster surveys conducted during 2013-2016 were included if they measured hemoglobin in refugee children aged 6-59 months and/or non-pregnant women aged 15-49 years. Prevalence of anemia, anemia DEFFs and ICCs, mean cluster size, number of clusters, and total sample size were calculated per-survey for non-pregnant women and children. Non-parametric tests were used to assess differences and correlations of ICC and DEFF between women and children and inter-regional differences. RESULTS: Eighty-seven unique cluster surveys from nine countries were included in this analysis. More than 90% of all surveys had ICC values for anemia below 0.10. Median ICC for children was 0.032 (IQR: 0.015-0.048), not significantly different from that observed for non-pregnant women for whom the median was 0.024 (IQR: -0.002-0.055). DEFFs were significantly higher for children [1.54 (IQR: 1.21-1.82)] versus women [1.20 (IQR: 0.99-1.46)]. Regional differences in DEFFs and ICCs were observed. CONCLUSIONS: Both ICCs and DEFF were relatively small for both non-pregnant women and preschool children and fall in a narrow range. Differences in ICCs between women and children were non-significant, suggesting similar inter-cluster distributions of anemia; significant differences in DEFF were likely attributable to differing cluster sizes. Given regional differences in both ICCs and DEFFs, location-specific values are preferred. However, in the absence of other context-specific information, we suggest using DEFFs of 1.4-1.8 if mean cluster size is around 20, and DEFFs of 1.2-1.4 if mean cluster size is around 10. |
Acceptability of urine diversion dry toilets in Dollo Ado refugee camp, Ethiopia
Patrick M , Tsige Y , Adow A , Abdirashid M , Yunis H , Githiri D , Hulland E , Murphy J , Akers P , Brown TW , Blanton C , Handzel T . Int J Hyg Environ Health 2021 234 113745 Given the increasing frequency and duration of humanitarian emergencies worldwide, there is a need to identify a greater range of effective and contextually appropriate water, sanitation and hygiene (WASH) interventions. Typical sanitation systems may be poorly suited for some of the conditions in which humanitarian emergencies can occur, such as in drought-prone regions. Urine-diversion dry toilets (UDDTs) are one potential alternative sanitation option which can be used in these conditions. Between 2014 and 2016, the U.S. Centers for Disease Control and Prevention (CDC) partnered with local agencies to evaluate the acceptability of UDDTs in a refugee camp in Ethiopia. The overall goals were to provide evidence regarding the level of adoption and satisfaction with UDDTs in this emergency context and the factors associated with satisfaction. Two cross-sectional surveys were conducted 18-months apart, using a stratified design to sample UDDT and latrine users for comparison. The proportion who reported to use their UDDT consistently was 88.8% (95% CI 85.1-92.5) in the first survey and 93.4% (95% CI 90.6-96.2) in the second survey. Reported satisfaction levels were significantly higher among respondents in the second survey (p < 0.0001), where 97.0% (95% CI 95.1-98.9) of respondents stated either that they were mostly or very satisfied with their UDDT. There was no significant difference detected in satisfaction between UDDT and latrine users (p = 0.28). Using a multivariable logistic regression model, we identified several factors associated with a higher level of satisfaction with UDDTs. Those who had previously (before coming to the camp) used a pit latrine (AOR = 4.2; 95% CI 1.4-12.7) or had no sanitation system (AOR = 2.4; 95% CI 1.3-4.4) relative to a pour-flush toilet, had a clean UDDT (AOR = 2.8; 95% CI 1.7-4.6), had been in the camp for a longer time period (AOR = 2.3; 95% CI 1.7-3.0), did not share their UDDT (AOR = 1.8; 95% CI 1.0-3.0) and had used their UDDT for a longer time period (AOR = 1.7; 95% CI 1.2-2.4) had higher odds of satisfaction. The findings demonstrate that UDDTs have been effectively introduced and utilized in this context and this may have implications for other humanitarian settings where they can be similarly managed. |
Patterns of posttraumatic stress symptoms among international humanitarian aid workers
Greene-Cramer BJ , Hulland EN , Russell SP , Eriksson CB , Lopes-Cardozo B . Traumatology 2020 27 (2) 177-184 Most studies of mental health in humanitarian aid workers have found low levels of posttraumatic stress disorder, making it hard to disaggregate and look at differences between subgroups. This study sought to identify the risk and protective factors associated with resistant, resilient, and nonresilient trajectories of stress response over time that could be used to inform more targeted training and organizational support programs for aid workers. Aid workers from 19 qualifying humanitarian organizations who aged >=18 years and were to deploy for 3 to 12 months completed questionnaires at 3 time points (pre, post, and follow-up). We identified 3 unique groups (nonresilient, resistant, and resilient) using latent class growth analysis and identified predictors of subgroup classification using multivariate logistic regression. Single individuals were less likely to be in the resilient group than in the resistant group compared to coupled individuals. Individuals with one prior deployment were three times more likely to be nonresilient than resistant compared to individuals with no previous deployments. There was no significant difference in resistant, resilient, and nonresilient classification for individuals with >2 deployments. Findings suggest a need for supplemental training and psychosocial support post the first deployment as well as resources focused on potential this should be cumulative rather than accumulative effects of stress and trauma exposure for more seasoned deployers.

Outcome of HIV testing among family members of index cases across 36 facilities in Abidjan, Cte d'Ivoire
Lasry A , Danho NK , Hulland EN , Diokouri AD , Kingbo MH , Doumatey NIL , Ekra AK , Ebah LG , Kouamé H , Hedje J , Jean-Baptiste AE . AIDS Behav 2020 25 (2) 554-561 In Côte d'Ivoire, the Family Approach to Counseling and Testing (FACT) program began in 2015 and provides facility-based HIV testing to the sexual partners, children and other household family members of HIV-positive index cases. We evaluated whether the FACT program is an effective approach to HIV case finding. We reviewed 1762 index patient charts to evaluate outcomes of the FACT program, held across 36 facilities in Abidjan. Index cases enumerated a total of 644 partners, 2301 children and 508 other family members including parents and siblings. Among the partners tested for HIV, the positivity rate was 21%; for children the positivity rate was 5% and for all other family members the positivity rate was 11%. Offering HIV testing services to the family members of HIV positive index cases is an effective approach to case finding in Côte d'Ivoire. Particularly, offering HIV testing to the partners of positive women index cases can be key to identifying previously undiagnosed men and linking them to treatment. |
Epidemiology and risk factors for extrapulmonary tuberculosis in Lebanon
O'Son L , Hulland E , Cookson ST , Castro KG , Yaacoub H . Int J Tuberc Lung Dis 2020 24 (4) 414-419 SETTING: Lebanon is a relatively low TB-burden country, but has a high proportion of extrapulmonary tuberculosis (EPTB). Concern has been expressed that Syrian-born refugees could add to the TB burden and rates of EPTB: since 2011, >1 000 000 Syrian refugees have entered Lebanon.OBJECTIVE: The Lebanese National Tuberculosis Programme (NTP) sought to identify factors for the high proportion of EPTB and to assess the potential impact of Syrian refugees.DESIGN: NTP line-listed data from 2014-2015 were analyzed with logistic regression identified risk factors for EPTB. A trend analysis for 2011-2015 assessed TB burden by nationality and site of TB.RESULTS: Of 1347 reported TB cases from 2014 to 2015, 507 (38%) were EPTB and 46% were Lebanese. In analysis limited to Lebanese-born, the proportion of EPTB cases was relatively stable, 47% in 2011 and 52% in 2015. Modeling identified risk factors for EPTB as being female (aOR 1.79, 95%CI 1.39-2.32) and 5-15 years old (aOR 3.31, 95%CI 1.47-7.45) compared with children aged <5 years. Between 2011 and 2015, the proportion of TB cases among Syrian-born increased from 3% in 2011 to 21% in 2015 (P < 0.001); however, the proportion of EPTB versus PTB cases among Syrians remained stable (P = 0.264).CONCLUSION: Syrian TB cases increased almost 10-fold in five years (2011-2015) but their contribution to EPTB did not change. The high proportion of EPTB in Lebanon and those aged 5-15 years merits further investigation. |
Concordance between estimates of acute malnutrition measured by weight-for-height and by mid-upper arm circumference after age adjustment: population-representative surveys from humanitarian settings
Leidman E , Couture A , Hulland E , Bilukha O . BMC Nutr 2019 5 39 Background: Mid-upper arm circumference (MUAC) and weight-for-height (WHZ) are commonly used indicators to identify acute malnutrition. However, MUAC and WHZ diagnose different children, and produce prevalence estimates that are meaningfully different. Previous research in Somalia has suggested improved concordance using MUAC-for-age (MUACZ) rather than MUAC. We further evaluate the relationship between MUACZ, MUAC, and WHZ using surveys conducted globally. Methods: We analyzed 882 population representative surveys from 41 countries. Children ages 6-59 months were classified as acutely malnourished using three independent criteria: WHZ < - 2 (WHZ2), MUAC< 125 mm (MUAC125), MUACZ < - 2 (MUACZ2). Population prevalence using each of the three criteria are presented by country and region. Correlations of survey prevalence for each indicator pair were assessed. Multivariable regression models of MUACZ and MUAC125 adjusted for WHZ2, stunting prevalence, age, and sex. To evaluate individual level diagnostic concordance, we compared the proportion of children identified by each of the three criteria. Results: Median prevalence of acute malnutrition overall was highest for MUACZ2 (14.0%) followed by WHZ2 (10.6%), and lowest for MUAC125 (7.3%). The absolute difference in prevalence between MUACZ2 and WHZ2 was smaller than the difference between MUAC125 and WHZ2 for 51.3% of surveys. The correlations of WHZ2 with both MUACZ2 as well as with MUAC125 were weak, positive associations (Pearson's r = 0.5757 and 0.4943, respectively), but MUAC125 and MUACZ2 had a strong, linear relationship (Pearson's r = 0.9265). The adjusted regression model for MUACZ2 had greater fit (R(2) = 0.50) relative to the adjusted model for MUAC125 (R(2) = 0.43). The proportion of children identified by both MUAC125 and WHZ2 was 25.5%, smaller than the proportion identified by both MUACZ2 and WHZ2 (30.6%). Conclusions: MUACZ identified more children as malnourished than MUAC, resulting in a higher prevalence of acute malnutrition in nearly all settings. Prevalence by MUACZ was not consistently more similar to WHZ than that estimated by MUAC, and correlations with WHZ were only slightly improved relative to MUAC. Consequently, programmatic use of MUACZ cannot be justified based on improved concordance with WHZ. Further research on morbidity and mortality of children with low MUACZ only are needed before recommending MUACZ for wider use. |
Systematic identification of facility-based stillbirths and neonatal deaths through the piloted use of an adapted RAPID tool in Liberia and Nepal
Greene-Cramer B , Boyd AT , Russell S , Hulland E , Tromble E , Widiati Y , Sharma S , Pun A , Roth Allen D , Dokubo EK , Handzel E . PLoS One 2019 14 (9) e0222583 Maternal, fetal, and neonatal health outcomes are interdependent. Designing public health strategies that link fetal and neonatal outcomes with maternal outcomes is necessary in order to successfully reduce perinatal and neonatal mortality, particularly in low- and middle- income countries. However, to date, there has been no standardized method for documenting, reporting, and reviewing facility-based stillbirths and neonatal deaths that links to maternal health outcomes would enable a more comprehensive understanding of the burden and determinants of poor fetal and neonatal outcomes. We developed and pilot-tested an adapted RAPID tool, Perinatal-Neonatal Rapid Ascertainment Process for Institutional Deaths (PN RAPID), to systematically identify and quantify facility-based stillbirths and neonatal deaths and link them to maternal health factors in two countries: Liberia and Nepal. This study found an absence of stillbirth timing documented in records, a high proportion of neonatal deaths occurring within the first 24 hours, and an absence of documentation of pregnancy-related and maternal factors that might be associated with fetal and neonatal outcomes. The use of an adapted RAPID methodology and tools was limited by these data gaps, highlighting the need for concurrent strengthening of death documentation through training and standardized record templates. |
Essential newborn care practice at four primary health facilities in conflict affected areas of Bossaso, Somalia: a cross-sectional study
Amsalu R , Morris CN , Chukwumalu K , Hynes M , Janjua S , Couture A , Summers A , Cannon A , Hulland EN , Baunach S . Confl Health 2019 13 27 Background: Newborn mortality is increasingly concentrated in contexts of conflict and political instability. However, there are limited guidelines and data on the availability and quality of newborn care in conflict settings. In 2016, an interagency collaboration developed the Newborn Health in Humanitarian Settings Field Guide- Interim version (Field Guide). In this study, we sought to understand the baseline availability and quality of essential newborn care in Bossaso, Somalia as part of an investigation to determine the feasibility and effectiveness of the Field Guide in improving newborn care in humanitarian settings. Methods: A cross-sectional study was conducted at four purposely selected health facilities serving internally displaced persons affected by conflict in Bossaso. Essential newborn care practice and patient experience with childbirth care received at the facilities were assessed via observation of clinical practice during childbirth and the immediate postnatal period, and through postnatal interviews of mothers. Descriptive statistics and logistic regression were employed to summarize and examine variation by health facility. Results: Of the 332 pregnant women approached, 253 (76.2%) consented and were enrolled. 97.2% (95% CI: 94.4, 98.9) had livebirths and 2.8% (95% CI: 1.1, 5.6) had stillbirths. The early newborn mortality was 1.7% (95% CI: 0.3, 4.8). Nearly all [95.7%, (95% CI: 92.4, 97.8)] births were attended by skilled health worker. Similarly, 98.0% (95% CI: 95.3, 99.3) of newborns received immediate drying, and 99.2% (95% CI: 97.1, 99.9) had delayed bathing. Few [8.6%, (95% CI: 5.4, 12.9)] received immediate skin-to-skin contact and the practice varied significantly by facility (p < 0.001). One-third of newborns [30.1%, (95% CI: 24.4, 36.2)] received early initiation of breastfeeding and there was significant variation by facility (p < 0.001). While almost all [99.2%, (95% CI: 97.2, 100)] service providers wore gloves while attending births, handwashing was not as common [20.2%, (95% CI: 15.4, 25.6)] and varied by facility (p < 0.001). Nearly all [92%, (95% CI: 86.9, 95.5)] mothers were either very happy or happy with the childbirth care received at the facility. Conclusion: Essential newborn care interventions were not universally available. Quality of care varied by health facility and type of intervention. Training and supervision using the Field Guide could improve newborn outcomes. |
Evaluation of an emergency bulk chlorination project targeting drinking water vendors in cholera-affected wards of Dar es Salaam and Morogoro, Tanzania
Rajasingham A , Hardy C , Kamwaga S , Sebunya K , Massa K , Mulungu J , Martinsen A , Nyasani E , Hulland E , Russell S , Blanton C , Nygren B , Eidex R , Handzel T . Am J Trop Med Hyg 2019 100 (6) 1335-1341 In August 2015, an outbreak of cholera was reported in Tanzania. In cholera-affected areas of urban Dar es Salaam and Morogoro, many households obtained drinking water from vendors, who sold water from tanks ranging in volume from 1,000 to 20,000 L. Water supplied by vendors was not adequately chlorinated. The Tanzanian Ministry of Health, Community Development, Gender, Elderly and Children and the U.N. Children's Fund, Tanzania, collaborated to enroll and train vendors to treat their water with 8.68-g sodium dichloroisocyanurate tablets. The CDC provided monitoring and evaluation support. Vendors were provided a 3-month supply of chlorine tablets. A baseline assessment and routine monitoring were conducted by ward environmental health officers. Approximately 3 months after chlorine tablet distribution, an evaluation of the program was conducted. The evaluation included a full enumeration of all vendors, an in-depth survey with half of the vendors enumerated, and focus group discussions. In total, 797 (88.9%) vendors were included in the full enumeration and 392 in the in-depth survey. Free residual chlorine (FRC) was detected in 12.0% of tanks at baseline and 69.6% of tanks during the evaluation; however, only 17.4% of these tanks had FRC >/= 0.5 mg/L. The results suggest high acceptability and use of the chlorine tablets by water vendors. However, given variation in the water source used and longer storage times, dosing could be increased in future programming. Bulk chlorination using chlorine tablets offers an efficient community-level approach to treating water closer to the point of use. |
Prevalence of mental disorders and epidemiological associations in post-conflict primary care attendees: a cross-sectional study in the Northern Province of Sri Lanka
Doherty S , Hulland E , Lopes-Cardozo B , Kirupakaran S , Surenthirakumaran R , Cookson S , Siriwardhana C . BMC Psychiatry 2019 19 (1) 83 BACKGROUND: Experiencing conflict and displacement can have a negative impact on an individual's mental health. Currently, prevalence of mental health disorders (MHDs) at the primary care level in post-conflict areas within the Northern Province of Sri Lanka is unknown. We aimed to explore this prevalence in conflict-affected populations attending primary care, using a structured package of validated screening tools for MHDs. METHODS: This cross-sectional study aimed to determine factors related to mental health disorders at the primary care level in Northern Province, Sri Lanka. A structured interview was conducted with internally displaced adults attending 25 randomly selected primary care facilities across all districts of Northern Sri Lanka (Jaffna, Mannar, Mullaitivu, Vavuniya). Participants were screened for depression, anxiety, psychosis, PTSD, and somatoform symptoms. RESULTS: Among 533 female and 482 male participants (mean age 53.2 years), the prevalence rate for any MHD was 58.8% (95% CI, 53.8-61.4), with 42.4% screening positive for two or more disorders (95% CI, 38.6-46.1). Anxiety prevalence was reported at 46.7% (95% CI, 41.9-51.5), depression at 41.1% (95% CI, 38.7-44.5), PTSD at 13.7% (95% CI, 10.6-16.8), somatoform symptoms at 27.6% (95% CI, 23.6-31.5), and psychosis with hypomania at 17.6% (95% CI, 13.3-21.9). CONCLUSION: This is the first study at the primary care level to investigate prevalence of MHDs among conflict-affected populations in the Northern Province, Sri Lanka. Results highlight unmet mental health needs in the region. Training intervention to integrate mental health services into primary care is planned. |
Alternative water transport and storage containers: Assessing sustained use of the PackH2O in rural Haiti
Martinsen A , Hulland E , Phillips R , Darius JA , Felker-Kantor E , Simpson D , Stephens M , Thomas E , Quick R , Handzel T . Am J Trop Med Hyg 2019 100 (4) 981-987 The PackH2O water backpack carrier was developed to provide safe storage and relieve stress of head-loading during water transport with traditional containers such as buckets and jerry cans. We conducted an evaluation to assess both self-reported and observed use over a 6-month period between November 2014 and May 2015. A total of 866 packs were distributed to 618 households in six communities in rural Haiti, and 431 and 441 households were surveyed at midline and end line, respectively. We performed linear regression to assess change of self-reported use over time. Although 79.3% of respondents reported continued use of the 20-L pack after 6 months, other measures of self-reported use were low, with only 16.8% reporting to have used the pack the last time they collected water and 10.3% preferring the pack over other water collection containers. In addition, only 10.2% of all people collecting water at community sources were observed using packs and 12.0% of all households surveyed had water in the pack at the time of visit. Pack use varied by community and demographics. Although women were targeted during distribution, men preferred the pack and were more commonly observed using it at the community water sources. In conclusion, the use of the PackH2O was not widely adopted in rural Haiti; however, further research is needed to assess the pack acceptance in areas where back-loading is more common and in emergency settings. |
Increase in reported cholera cases in Haiti following Hurricane Matthew: An interrupted time series model
Hulland E , Subaiya S , Pierre K , Barthelemy N , Pierre JS , Dismer A , Juin S , Fitter D , Brunkard J . Am J Trop Med Hyg 2019 100 (2) 368-373 Matthew, a category 4 hurricane, struck Haiti on October 4, 2016, causing widespread flooding and damage to buildings and crops, and resulted in many deaths. The damage caused by Matthew raised concerns of increased cholera transmission particularly in Sud and Grand'Anse departments, regions which were hit most heavily by the storm. To evaluate the change in reported cholera cases following Hurricane Matthew on reported cholera cases, we used interrupted time series regression models of daily reported cholera cases, controlling for the impact of both rainfall, following a 4-week lag, and seasonality, from 2013 through 2016. Our results indicate a significant increase in reported cholera cases after Matthew, suggesting that the storm resulted in an immediate surge in suspect cases, and a decline in reported cholera cases in the 46-day post-storm period, after controlling for rainfall and seasonality. Regression models stratified by the department indicate that the impact of the hurricane was regional, with larger surges in the two most highly storm-affected departments: Sud and Grand'Anse. These models were able to provide input to the Ministry of Health in Haiti on the national and regional impact of Hurricane Matthew and, with further development, could provide the flexibility of use in other emergency situations. This article highlights the need for continued cholera prevention and control efforts, particularly in the wake of natural disasters such as hurricanes, and the continued need for intensive cholera surveillance nationally. |
High levels of HIV-1 drug resistance in children who acquired HIV infection through mother to child transmission in the era of Option B+, Haiti, 2013-2014
Louis FJ , Segaren N , Desinor O , Beard RS , Jean-Louis R , Chang J , Boisson S , Hulland EN , Wagar N , DeVos J , Francois K , Buteau J , Boncy J , Marston BJ , Domercant JW , Yang C , Charles M . Pediatr Infect Dis J 2018 38 (5) 503-507 BACKGROUND: The main objective of this study was to determine the frequency and patterns of HIVDR-associated mutations among children <18 months old born to HIV-1-positive mothers enrolled in the prevention of mother-to-child transmission (PMTCT) services in Haiti. METHODS: Between January 1, 2013 and December 31, 2014, HIV-positive remnant dried blood spots (DBS) collected from children under 18 months old for Early Infant Diagnosis (EID) at the National Public Health Laboratory were used for HIV-1 genotyping. HIVDR mutations were analyzed using the Stanford Drug Resistance HIVdb program. RESULTS: Of the 3,555 DBS collected for EID, 360 (10.1%) were HIV-positive and 355 were available for genotyping. Of these, 304 (85.6%) were successfully genotyped and 217 (71.4%) had >/= one DR mutation. Mutations conferring resistance to NRTIs and NNRTIs were present in 40.5% (123) and 69.1% (210), respectively. The most frequent mutations were K103N/S (48.0%), M184V (37.5%), and G190A/S (15.1%), and Y181C/G/V (14.1%). Predicted drug resistance analysis revealed that 68.8% of the children had high-level resistance to NNRTIs and 11.5% had intermediate to high-level resistance to abacavir. CONCLUSIONS: This study showed high rates of resistance to NRTIs and NNRTIs among newly HIV-diagnosed children in Haiti, suggesting that in the era of "option B+" (initiation of lifelong combination antiretroviral therapy to pregnant women with HIV), the majority of children who acquire HIV infection through MTCT have resistant HIV. These results have led the National HIV Program to revise the pediatric guidelines to include protease inhibitors in first-line regimens for all HIV-positive newborns. |
Trends in hepatitis B and hepatitis C seroprevalence among blood donors - Haiti, 2005-2014
Baptiste AEJ , Chevalier MS , Polo E , Noel E , Hulland EN , Archer WR . ISBT Sci Ser 2018 13 (2) 150-157 Background and Objectives: Data on the seroprevalence of viral hepatitis are limited in Haiti; consequently, the epidemiology is poorly described. This study aims to provide a descriptive analysis of hepatitis B virus (HBV) and hepatitis C virus (HCV) seroprevalence of blood donations in Haiti. Materials and Methods: Using Haiti's National Blood Safety Program and Haitian Red Cross reports from 2005 to 2014, we analysed the results of screening tests of donor serum samples to assess HBV and HCV seroprevalence among adults aged 17 to 65 years. Results: A total of 198 758 donor samples were screened from 2005 to 2014, of which 0.56% were positive for antibody to hepatitis C virus (anti-HCV) and 3.80% were positive for hepatitis B surface antigen. Over the 10-year study period, anti-HCV seroprevalence among blood donors increased by 31% from 0.66% to 0.86% (95% CI: 1.01-1.70); however, this trend was not uniform over time, with a significant decrease from 0.66% in 2005 to 0.39% in 2009 (95% CI: 0.43- 0.82) and 0.43% in 2012 (95% CI: 0.50-0.90). Conversely, HBV decreased significantly by 13% from 3.95% in 2005 to 3.42% in 2014 (95% CI: 0.77-0.97), a trend that was also observed in 2012 and 2013. Conclusion: The significant, uniform decrease in HBV seroprevalence in more recent years may represent the positive impact of public health interventions in preventing the transmission of blood-borne infections. More research is needed to understand why the trends in HCV transmission are non-uniform and to investigate the significant increase in more recent years. |
Virologic outcome among patients receiving antiretroviral therapy at five hospitals in Haiti
Jean Louis F , Buteau J , Francois K , Hulland E , Domercant JW , Yang C , Boncy J , Burris R , Pelletier V , Wagar N , Deyde V , Lowrance DW , Charles M . PLoS One 2018 13 (1) e0192077 INTRODUCTION: Viral load (VL) assessment is the preferred method for diagnosing and confirming virologic failure for patients on antiretroviral therapy (ART). We conducted a retrospective cross-sectional study to evaluate the virologic suppression rate among patients on ART for >/=6 months in five hospitals around Port-au-Prince, Haiti. METHODS: Plasma VL was measured and patients with VL <1,000 copies/mL were defined as virologically suppressed. A second VL test was performed within at least six months of the first test. Factors associated with virologic suppression were analyzed using logistic regression models accounting for site-level clustering using complex survey procedures. RESULTS: Data were analyzed for 2,313 patients on ART for six months or longer between July 2013 and February 2015. Among them, 1,563 (67.6%) achieved virologic suppression at the first VL test. A second VL test was performed within at least six months for 718 (31.0%) of the patients. Of the 459 patients with an initial HIV-1 RNA <1,000 copies/mL who had a second VL performed, 394 (85.8%) maintained virologic suppression. Virologic suppression was negatively associated with male gender (adjusted odds ratio [aOR]: 0.80, 95% CI: 0.74-0.0.86), 23 to 35 months on ART (aOR:0.72[0.54-0.96]), baseline CD4 counts of 201-500 cells/mm3 and 200 cells/mm3 or lower (aORs: 0.77 [0.62-0.95] and 0.80 [0.66-0.98], respectively), poor adherence (aOR: 0.69 [0.59-0.81]), and TB co-infection (aOR: 0.73 [0.55-0.97]). CONCLUSIONS: This study showed that over two-thirds of the patients in this evaluation achieved virologic suppression after >/= six months on ART and the majority of them remained suppressed. These results reinforce the importance of expanding access to HIV-1 viral load testing in Haiti for monitoring ART outcomes. |
Using a quality improvement approach to improve maternal and neonatal care in North Kivu, Democratic Republic of Congo
Hynes M , Meehan K , Meyers J , Mashukano Maneno L , Hulland E . Reprod Health Matters 2017 25 (51) 1-11 Providing quality health care services in humanitarian settings is challenging due to population displacement, lack of qualified staff and supervisory oversight, and disruption of supply chains. This study explored whether a participatory quality improvement (QI) intervention could be used in a protracted conflict setting to improve facility-based maternal and newborn care. A longitudinal quasi-experimental design was used to examine delivery of maternal and newborn care components at 12 health facilities in eastern Democratic Republic of Congo. Study facilities were split into two groups, with both groups receiving an initial "standard" intervention of clinical training. The "enhanced" intervention group then applied a QI methodology, which involved QI teams in each facility, supported by coaches, testing small changes to improve care. This paper presents findings on two of the study outcomes: delivery of active management of the third stage of labour (AMTSL) and essential newborn care (ENC). We measured AMTSL and ENC through exit interviews with post-partum women and matched partographs at baseline and endline over a 9-month period. Using generalised equation estimation models, the enhanced intervention group showed a greater rate of change than the control group for AMTSL (aOR 3.47, 95% CI: 1.17-10.23) and ENC (OR: 49.62, 95% CI: 2.79-888.28), and achieved 100% ENC completion at endline. This is one of the first studies where this QI methodology has been used in a protracted conflict setting. A method where health staff take ownership of improving care is of even greater value in a humanitarian context where external resources and support are scarce. |
Seroprevalence of herpes simplex virus type-2 (HSV-2) among pregnant women who participated in a national HIV surveillance activity in Haiti
Domercant JW , Jean Louis F , Hulland E , Griswold M , Andre-Alboth J , Ye T , Marston BJ . BMC Infect Dis 2017 17 (1) 577 BACKGROUND: Herpes simplex virus type 2 (HSV-2), one the most common causes of genital ulcers, appears to increase both the risk of HIV acquisition and HIV transmission. HSV-2/HIV co-infection among pregnant women may increase the risk of perinatal transmission of HIV. This study describes rates of HSV-2 among pregnant women in Haiti and HSV-2 test performance in this population. METHODS: Unlinked residual serum specimens from the 2012 National HIV and Syphilis Sentinel Surveillance Survey among pregnant women in Haiti were tested using two commercial kits (Focus HerpeSelect, Kalon) for HSV-2 antibodies. We evaluated rates of HSV-2 seropositivity and HSV-2/HIV co-infection, associations between HSV-2 and demographic characteristics using multivariable Cox proportional hazards modeling, and HSV-2 test performance in this population. RESULTS: Serum samples from 1000 pregnant women (all 164 HIV positive and 836 random HIV negative) were selected. The overall weighted prevalence of HSV-2 was 31.4% (95% CI: 27.7-35.4) and the prevalence of HIV-positivity among HSV-2 positive pregnant women was five times higher than the prevalence among HSV-2 negative women (4.8% [95% CI: 3.9-6.0] vs. 0.9% [95% CI: 0.6-1.3], respectively). Factors significantly associated with HSV-2 positivity were HIV-positivity (PR: 2.27 [95% CI: 1.94-2.65]) and older age (PRs: 1.41 [95% CI: 1.05-1.91] for 20-24 years, 1.71 [95% CI:1.13-2.60] for 30-34 years, and 1.55 [95% CI: 1.10-2.19] for 35 years or greater]), while rural residence was negatively associated with HSV-2 positivity (PR 0.83 [95% CI: 0.69-1.00]), after controlling for other covariables. For this study a conservative Focus index cutoff of 3.5 was used, but among samples with a Focus index value ≥2.5, 98.4% had positive Kalon tests. CONCLUSION: The prevalence of HSV-2 is relatively high among pregnant women in Haiti. Public health interventions to increase access to HSV-2 screening in antenatal services are warranted. |
Use of Rapid Ascertainment Process for Institutional Deaths (RAPID) to identify pregnancy-related deaths in tertiary-care obstetric hospitals in three departments in Haiti
Boyd AT , Hulland EN , Grand'Pierre R , Nesi F , Honore P , Jean-Louis R , Handzel E . BMC Pregnancy Childbirth 2017 17 (1) 145 BACKGROUND: Accurate assessment of maternal deaths is difficult in countries lacking standardized data sources for their review. As a first step to investigate suspected maternal deaths, WHO suggests surveillance of "pregnancy-related deaths", defined as deaths of women while pregnant or within 42 days of termination of pregnancy, irrespective of cause. Rapid Ascertainment Process for Institutional Deaths (RAPID), a surveillance tool, retrospectively identifies pregnancy-related deaths occurring in health facilities that may be missed by routine surveillance to assess gaps in reporting these deaths. METHODS: We used RAPID to review pregnancy-related deaths in six tertiary obstetric care facilities in three departments in Haiti. We reviewed registers and medical dossiers of deaths among women of reproductive age occurring in 2014 and 2015 from all wards, along with any additional available dossiers of deaths not appearing in registers, to capture pregnancy status, suspected cause of death, and timing of death in relation to the pregnancy. We used capture-recapture analyses to estimate the true number of in-hospital pregnancy-related deaths in these facilities. RESULTS: Among 373 deaths of women of reproductive age, we found 111 pregnancy-related deaths, 25.2% more than were reported through routine surveillance, and 22.5% of which were misclassified as non-pregnancy-related. Hemorrhage (27.0%) and hypertensive disorders (18.0%) were the most common categories of suspected causes of death, and deaths after termination of pregnancy were statistically significantly more common than deaths during pregnancy or delivery. Data were missing at multiple levels: 210 deaths had an undetermined pregnancy status, 48.7% of pregnancy-related deaths lacked specific information about timing of death in relation to the pregnancy, and capture-recapture analyses in three hospitals suggested that approximately one-quarter of pregnancy-related deaths were not captured by RAPID or routine surveillance. CONCLUSIONS: Across six tertiary obstetric care facilities in Haiti, RAPID identified unreported pregnancy-related deaths, and showed that missing data was a widespread problem. RAPID is a useful tool to more completely identify facility-based pregnancy-related deaths, but its repeated use would require a concomitant effort to systematically improve documentation of clinical findings in medical records. Limitations of RAPID demonstrate the need to use it alongside other tools to more accurately measure and address maternal mortality. |
Quality and uptake of antenatal and postnatal care in Haiti
Mirkovic KR , Lathrop E , Hulland EN , Jean-Louis R , Lauture D , D'Alexis GD , Hanzel E , Grand-Pierre R . BMC Pregnancy Childbirth 2017 17 (1) 52 BACKGROUND: Despite improvement, maternal mortality in Haiti remains high at 359/100,000 live births. Improving access to high quality antenatal and postnatal care has been shown to reduce maternal mortality and improve newborn outcomes. Little is known regarding the quality and uptake of antenatal and postnatal care among Haitian women. METHODS: Exit interviews were conducted with all pregnant and postpartum women seeking care from large health facilities (n = 10) in the Nord and Nord-Est department and communes of St. Marc, Verrettes, and Petite Riviere in Haiti over the study period (March-April 2015; 3-4 days/facility). Standard questions related to demographics, previous pregnancies, current pregnancy, and services/satisfaction during the visit were asked. Total number of antenatal visits were abstracted from charts of recently delivered women (n = 1141). Provider knowledge assessments were completed by antenatal and postnatal care providers (n = 39). Frequencies were calculated for descriptive variables and multivariable logistic regression was used to explore predictors of receiving 5 out of 10 counseling messages among pregnant women. RESULTS: Among 894 pregnant women seeking antenatal care, most reported receiving standard clinical service components during their visit (97% were weighed, 80% had fetal heart tones checked), however fewer reported receiving recommended counseling messages (44% counselled on danger signs, 33% on postpartum family planning). Far fewer women were seeking postnatal care (n = 63) and similar service patterns were reported. Forty-three percent of pregnant women report receiving at least 5 out of 10 counseling messages. Pregnant women on a repeat visit and women with greater educational attainment had greater odds of reporting having received 5 out of 10 counseling messages (2nd visit: adjusted odds ratio [aOR] =1.70, 95% confidence interval [CI]: 1.09-2.66; 5+ visit: aOR = 5.44, 95% CI: 2.91-10.16; elementary school certificate: aOR = 2.06, 95% CI: 1.17-3.63; finished secondary school or more aOR = 1.97, 95% CI = 1.05-3.02). Chart reviews indicate 27% of women completed a single antenatal visit and 36% completed the recommended 4 visits. CONCLUSIONS: Antenatal and postnatal care uptake in Haiti is sub-optimal. Despite frequent reports of provision of standard service components, counseling messages are low. Consistent provision of standardized counseling messages with regular provider trainings is recommended to improve quality and uptake of care in Haiti. |
Parameters associated with design effect of child anthropometry indicators in small-scale field surveys
Hulland EN , Blanton CJ , Leidman EZ , Bilukha OO . Emerg Themes Epidemiol 2016 13 13 BACKGROUND: Cluster surveys provide rapid but representative estimates of key nutrition indicators in humanitarian crises. For these surveys, an accurate estimate of the design effect is critical to calculate a sample size that achieves adequate precision with the minimum number of sampling units. This paper describes the variability in design effect for three key nutrition indicators measured in small-scale surveys and models the association of design effect with parameters hypothesized to explain this variability. METHODS: 380 small-scale surveys from 28 countries conducted between 2006 and 2013 were analyzed. We calculated prevalence and design effect of wasting, underweight, and stunting for each survey as well as standard deviations of the underlying continuous Z-score distribution. Mean cluster size, survey location and year were recorded. To describe design effects, median and interquartile ranges were examined. Generalized linear regression models were run to identify potential predictors of design effect. RESULTS: Median design effect was under 2.00 for all three indicators; for wasting, the median was 1.35, the lowest among the indicators. Multivariable linear regression models suggest significant, positive associations of design effect and mean cluster size for all three indicators, and with prevalence of wasting and underweight, but not stunting. Standard deviation was positively associated with design effect for wasting but negatively associated for stunting. Survey region was significant in all three models. CONCLUSIONS: This study supports the current field survey guidance recommending the use of 1.5 as a benchmark for design effect of wasting, but suggests this value may not be large enough for surveys with a primary objective of measuring stunting or underweight. The strong relationship between design effect and region in the models underscores the continued need to consider country- and locality-specific estimates when designing surveys. These models also provide empirical evidence of a positive relationship between design effect and both mean cluster size and prevalence, and introduces standard deviation of the underlying continuous variable (Z-scores) as a previously unexplored factor significantly associated with design effect. The magnitude and directionality of this association differed by indicator, underscoring the need for further investigation into the relationship between standard deviation and design effect. |
Handheld solar light use, durability, and retention among women and girls in internally displaced persons camps in Haiti - 2013-2014
Dynes M , Rosenthal M , Hulland E , Hardy C , Torre L , Tomczyk B . Int J Disaster Risk Reduct 2016 18 162-170 During conflict and disasters, women and girls are at increased risk of gender based violence. International humanitarian guidelines call for the distribution of individual lighting to meet women and girls' basic needs and to reduce risk of violence; however, little evidence exists to support these guidelines. This paper presents an evaluation of handheld solar light use, retention, and durability among women and girls living in two internally displaced persons camps in Port-au-Prince, Haiti. Data was gathered prospectively via five household surveys from August 2013 to April 2014; a total of 754 females participated in the study. Women reported going outside at night more frequently at the end of the study than at the beginning. The handheld solar lights were the most common source of lighting at endline, whereas candle and gas lamp use declined significantly over time. Results from a Life-Table survival analysis estimated that households had an 83% probability of still owning a functioning light after seven months. Given the frequent use, acceptable durability, and retention of the lights, donors and humanitarian organizations should consider supporting light distribution to women and girls in internally displaced persons camps to help meet their basic needs. © 2016. |
