BMC Infect Dis 2025 25 (1) 317 ![]() ![]() ![]() BACKGROUND: In October 2022, the Uganda Ministry of Health (MoH) confirmed the first case of a Sudan Virus Disease (SVD) outbreak in the Kampala Metropolitan area (KMA). A multicomponent infection prevention and control (IPC) strategy was implemented to control the spread of Orthoebolavirus sudanense (SUDV) in KMA. We describe the deployment of this strategy, its effect on IPC capacities, and the successful control of the SVD outbreak in KMA during the 2022 outbreak. METHODOLOGY: The multicomponent IPC strategy included (1) IPC pillar coordination: an IPC task force convened by government and health partner representatives and designated focal persons at the district level (2) Ring IPC: intense and targeted IPC support was developed to provide support to healthcare facilities (HCFs) and communities around each confirmed case, (3) IPC in HCFs: HCFs were assessed using a modified WHO SVD IPC scorecard rapid assessment tool that measured 15 IPC capacity domains, mentorship and IPC supplies were provided to HCFs with low scores on the rapid assessment. RESULTS: A KMA task force was established, and 13 IPC Rings were activated; 790 HCFs were assessed for IPC readiness, and 2,235 healthcare workers (HCWs) were trained. The mean (± standard-deviation) IPC score was 59.2% (± 18.6%) at baseline and increased to 65.5% (± 14.7%) at follow-up after 2 weeks (p < 0.001) of support. The mean IPC scores at baseline were lowest for primary HCFs (57%) and private-for-profit HCFs (47.1%). Similar gaps were revealed across all HCFs, with eight out of 15 (53.3%) IPC capacity areas assessed, resulting in scores < 50% at baseline. At follow-up, only four out of 15 (26.7%) capacity areas (26.7%) were below this threshold. CONCLUSION: The IPC strategy enhanced the IPC capacities at HCFs and could be adopted for future outbreaks. Leadership commitment and resource allocation to IPC during non-outbreak periods are critical for preparedness, rapid response, and access to safe care. |
Identifying the priority infection prevention and control gaps contributing to neonatal healthcare-associated infections in low-and middle-income countries: results from a modified Delphi process
Yee D , Osuka H , Weiss J , Kriengkauykiat J , Kolwaite A , Johnson J , Hopman J , Coffin S , Ram P , Serbanescu F , Park B . J Glob Health Rep 12/28/2021 5 BACKGROUND: In low- and middle-income countries (LMIC), neonatal healthcare-associated infections (HAI) are associated with increased morbidity, mortality, hospital stay, and costs. When resources are limited, addressing HAI through infection prevention and control (IPC) requires prioritizing interventions to maximize impact. However, little is known about the gaps in LMIC that contribute most to HAI. METHODS: A literature review was conducted to identify the leading IPC gaps contributing to neonatal HAIs in intensive care units and specialty care wards in LMIC. Additionally, a panel of 21 global experts in neonatology and IPC participated in an in-person modified Delphi process to achieve consensus on the relative importance of these gaps as contributors to HAI. RESULTS: Thirteen IPC gaps were identified and summarized into four main categories: facility policies such as prioritizing a patient safety culture and maintaining facility capacity, general healthcare worker behaviors such as hand hygiene and proper device insertion and maintenance, specialty healthcare worker behaviors such as cleaning and reprocessing of medical equipment, and infrastructural considerations such as adequate medical equipment and hand hygiene supplies. CONCLUSIONS: Through a modified Delphi process, we identified the leading IPC gaps contributing to neonatal HAIs; this information can assist policymakers, public health officials, researchers, and clinicians to prioritize areas for further study or intervention. |
Associations between childhood opportunity index and pediatric cardiac surgical outcomes
Kolwaite AR , Edwards JA , Higgins M , Kandaswamy S , Orenstein E , Boughton D , Zinyandu T , Brasher S , Shashidharan S , Thompson LM , Chanani NK . J Pediatr 2024 114000 OBJECTIVE: To assess the relationship between the Childhood Opportunity Index (COI), a comprehensive measurement of social determinants of health (SDOH), and specific COI domains on patient-specific outcomes following congenital cardiac surgery in the metropolitan region of Atlanta, Georgia. STUDY DESIGN: In this retrospective chart review, we included patients who underwent an index operation for congenital heart disease (CHD) between 2010 and 2020 in a single pediatric health care system. Patients' addresses were geocoded and mapped to census tracts. Descriptive statistics, univariable analysis, and multivariable regression models were employed to assess associations between variables and outcomes. RESULTS: Of the 7460 index surgeries, 3798 (51%) met eligibility criteria. Presence of an adverse outcome, defined as either mortality or one of several other major post-operative morbidities, was significantly associated with COI in the univariable model (p=0.008), but not the multivariable regression model (p=0.39). Postoperative hospital length of stay (PHLOS) was significantly associated with COI (p<0.001) in univariable and multivariable regression models. There was no significant association between COI and readmission within 30 days of hospital discharge in univariable (p<0.094) and multivariable (p=0.49) models. CONCLUSION: COI is associated with PHLOS but not all outcomes in patients after congenital heart surgery. By understanding the role of COI in outcomes related to cardiac surgery, targeted interventions can be developed to improve health equity. |
Ebola virus disease nosocomial infections in the Democratic Republic of the Congo: a descriptive study of cases during the 2018-2020 outbreak
Hazim CE , Kolwaite A , Blaney DD , Choi MJ , Park B , Montgomery JM . Int J Infect Dis 2021 115 126-133 OBJECTIVES: To describe the characteristics of cases of Ebola virus disease (EVD) nosocomial infections (NIs) in the Democratic Republic of the Congo, July 2018-May 2020, to inform future interventions. METHODS: We identified cases of NI during EVD outbreak response surveillance, and conducted a retrospective analysis of cases according to demographic characteristics and health facility (HF) type. RESULTS: Of 3481 cases of EVD, 579 (16.6%) were NIs, 332 of which occurred in women (57.3%). Patients and visitors accounted for 419 cases (72.4%), of which 79 (18.9%) were aged from 6 to ≤ 18 years and 108 (25.8%) were aged ≤ 5 years. Health workers (HWs) accounted for the remaining 160 (27.6%) NI cases. Case fatality rate (CFR) among HWs (66/160; 41.3%) was significantly lower than among patients and visitors (292/419; 69.7%) (p < 0.001). CFR was higher among those aged 6-18 years (54/79; 68.4%) and ≤ 5 years (89/108; 82.4%). Referral HFs (> 39 beds) had the highest prevalence of EVD NI (148/579; 25.6%). Among HFs with at least one case of NI, 50.0% (98/196) were privately owned. CONCLUSIONS: nurses and traditional healers should be targeted for IPC training, and supportive supervision provided to HFs to mitigate EVD transmission. |
Molecular epidemiology of carbapenem-resistant Enterobacterales in Thailand, 2016-2018.
Paveenkittiporn W , Lyman M , Biedron C , Chea N , Bunthi C , Kolwaite A , Janejai N . Antimicrob Resist Infect Control 2021 10 (1) 88 ![]() BACKGROUND: Carbapenem-resistant Enterobacterales (CRE) is a global threat. Enterobacterales develops carbapenem resistance through several mechanisms, including the production of carbapenemases. We aim to describe the prevalence of Carbapenem-resistant Enterobacterales (CRE) with and without carbapenemase production and distribution of carbapenemase-producing (CP) genes in Thailand using 2016-2018 data from a national antimicrobial resistance surveillance system developed by the Thailand National Institute of Health (NIH). METHODS: CRE was defined as any Enterobacterales resistant to ertapenem, imipenem, or meropenem. Starting in 2016, 25 tertiary care hospitals from the five regions of Thailand submitted the first CRE isolate from each specimen type and patient admission to Thailand NIH, accompanied by a case report form with patient information. NIH performed confirmatory identification and antimicrobial susceptibility testing and performed multiplex polymerase chain reaction testing to detect CP-genes. Using 2016-2018 data, we calculated proportions of CP-CRE, stratified by specimen type, organism, and CP-gene using SAS 9.4. RESULTS: Overall, 4,296 presumed CRE isolates were submitted to Thailand NIH; 3,946 (93%) were confirmed CRE. Urine (n = 1622, 41%) and sputum (n = 1380, 35%) were the most common specimen types, while blood only accounted for 323 (8%) CRE isolates. The most common organism was Klebsiella pneumoniae (n = 2660, 72%), followed by Escherichia coli (n = 799, 22%). The proportion of CP-CRE was high for all organism types (range: 85-98%). Of all CRE isolates, 2909 (80%) had one CP-gene and 629 (17%) had > 1 CP-gene. New Delhi metallo-beta-lactamase (NDM) was the most common CP-gene, present in 2392 (65%) CRE isolates. K. pneumoniae carbapenemase (KPC) and Verona integron-encoded metallo-β-lactamase (VIM) genes were not detected among any isolates. CONCLUSION: CP genes were found in a high proportion (97%) of CRE isolates from hospitals across Thailand. The prevalence of NDM and OXA-48-like genes in Thailand is consistent with pattern seen in Southeast Asia, but different from that in the United States and other regions. As carbapenemase testing is not routinely performed in Thailand, hospital staff should consider treating all patients with CRE with enhanced infection control measures; in line with CDC recommendation for enhanced infection control measures for CP-CRE because of their high propensity to spread. |
Core components of infection prevention and control programs at the facility level in Georgia: key challenges and opportunities
Deryabina A , Lyman M , Yee D , Gelieshvilli M , Sanodze L , Madzgarashvili L , Weiss J , Kilpatrick C , Rabkin M , Skaggs B , Kolwaite A . Antimicrob Resist Infect Control 2021 10 (1) 39 BACKGROUND: The Georgia Ministry of Labor, Health, and Social Affairs is working to strengthen its Infection Prevention and Control (IPC) Program, but until recently has lacked an assessment of performance gaps and implementation challenges faced by hospital staff. METHODS: In 2018, health care hospitals were assessed using a World Health Organization (WHO) adapted tool aimed at implementing the WHO's IPC Core Components. The study included site assessments at 41 of Georgia's 273 hospitals, followed by structured interviews with 109 hospital staff, validation observations of IPC practices, and follow up document reviews. RESULTS: IPC programs for all hospitals were not comprehensive, with many lacking defined objectives, workplans, targets, and budget. All hospitals had at least one dedicated IPC staff member, 66% of hospitals had IPC staff with some formal IPC training; 78% of hospitals had IPC guidelines; and 55% had facility-specific standard operating procedures. None of the hospitals conducted structured monitoring of IPC compliance and only 44% of hospitals used IPC monitoring results to make unit/facility-specific IPC improvement plans. 54% of hospitals had clearly defined priority healthcare-associated infections (HAIs), standard case definitions and data collection methods in their HAI surveillance systems. 85% hospitals had access to a microbiology laboratory. All reported having posters or other tools to promote hand hygiene, 29% had them for injection safety. 68% of hospitals had functioning hand-hygiene stations available at all points of care. 88% had single patient isolation rooms; 15% also had rooms for cohorting patients. 71% reported having appropriate waste management system. CONCLUSIONS: Among the recommended WHO IPC core components, existing programs, infrastructure, IPC staffing, workload and supplies present within Georgian healthcare hospitals should allow for implementation of effective IPC. Development and dissemination of IPC Guidelines, implementation of an effective IPC training system and systematic monitoring of IPC practices will be an important first step towards implementing targeted IPC improvement plans in hospitals. |
An innovative quality improvement approach for rapid improvement of infection prevention and control at health facilities in Sierra Leone
Rondinelli I , Dougherty G , Madevu-Matson CA , Toure M , Akinjeji A , Ogongo I , Kolwaite A , Weiss J , Gleason B , Lyman MM , Benya H , Rabkin M . Int J Qual Health Care 2020 32 (2) 85-92 QUALITY CHALLENGE: The Sierra Leone (SL) Ministry of Health and Sanitation's National Infection Prevention and Control Unit (NIPCU) launched National Infection and Prevention Control (IPC) Policy and Guidelines in 2015, but a 2017 assessment found suboptimal compliance with standards on environmental cleanliness (EC), waste disposal (WD) and personal protective equipment (PPE) use. METHODS: ICAP at Columbia University (ICAP), NIPCU and the Centers for Disease Control and Prevention (CDC) designed and implemented a Rapid Improvement Model (RIM) quality improvement (QI) initiative with a compressed timeframe of 6 months to improve EC, WD and PPE at eight purposively selected health facilities (HFs). Targets were collaboratively developed, and a 37-item checklist was designed to monitor performance. HF teams received QI training and weekly coaching and convened monthly to review progress and exchange best practices. At the final learning session, a "harvest package" of the most effective ideas and tools was developed for use at additional HFs. RESULTS: The RIM resulted in marked improvement in WD and EC performance and modest improvement in PPE. Aggregate compliance for the 37 indicators increased from 67 to 96% over the course of 4 months, with all HFs showing improvement. Average PPE compliance improved from 85 to 89%, WD from 63 to 99% and EC from 51 to 99%. LESSONS LEARNED: The RIM QIC approach is feasible and effective in SL's austere health system and led to marked improvement in IPC performance. The best practices are being scaled up and the RIM QIC methodology is being applied to other domains. |
Creation of a national infection prevention and control programme in Sierra Leone, 2015
Kanu H , Wilson K , Sesay-Kamara N , Bennett S , Mehtar S , Storr J , Allegranzi B , Benya H , Park B , Kolwaite A . BMJ Glob Health 2019 4 (3) e001504 Prior to the 2014-2016 Ebola epidemic, Sierra Leone's Ministry of Health and Sanitation had no infection prevention and control programme. High rates of Ebola virus disease transmission in healthcare facilities underscored the need for infection prevention and control in the healthcare system. The Ministry of Health and Sanitation led an effort among international partners to rapidly stand up a national infection prevention and control programme to decrease Ebola transmission in healthcare facilities and strengthen healthcare safety and quality. Leadership and ownership by the Ministry of Health and Sanitation was the catalyst for development of the programme, including the presence of an infection prevention and control champion within the ministry. A national policy and guidelines were drafted and approved to outline organisation and standards for the programme. Infection prevention and control focal persons were identified and embedded at public hospitals to manage implementation. The Ministry of Health and Sanitation and international partners initiated training for new infection prevention and control focal persons and committees. Monitoring systems to track infection prevention and control implementation were also established. This is a novel example of rapid development of a national infection prevention and control programme under challenging conditions. The approach to rapidly develop a national infection prevention and control programme in Sierra Leone may provide useful lessons for other programmes in countries or contexts starting from a low baseline for infection prevention and control. © Author(s) (or their employer(s)) 2019. |
Infection prevention and control for Ebola in health care settings - West Africa and United States
Hageman JC , Hazim C , Wilson K , Malpiedi P , Gupta N , Bennett S , Kolwaite A , Tumpey A , Brinsley-Rainisch K , Christensen B , Gould C , Fisher A , Jhung M , Hamilton D , Moran K , Delaney L , Dowell C , Bell M , Srinivasan A , Schaefer M , Fagan R , Adrien N , Chea N , Park BJ . MMWR Suppl 2016 65 (3) 50-6 The 2014-2016 Ebola virus disease (Ebola) epidemic in West Africa underscores the need for health care infection prevention and control (IPC) practices to be implemented properly and consistently to interrupt transmission of pathogens in health care settings to patients and health care workers. Training and assessing IPC practices in general health care facilities not designated as Ebola treatment units or centers became a priority for CDC as the number of Ebola virus transmissions among health care workers in West Africa began to affect the West African health care system and increasingly more persons became infected. CDC and partners developed policies, procedures, and training materials tailored to the affected countries. Safety training courses were also provided to U.S. health care workers intending to work with Ebola patients in West Africa. As the Ebola epidemic continued in West Africa, the possibility that patients with Ebola could be identified and treated in the United States became more realistic. In response, CDC, other federal components (e.g., Office of the Assistant Secretary for Preparedness and Response) and public health partners focused on health care worker training and preparedness for U.S. health care facilities. CDC used the input from these partners to develop guidelines on IPC for hospitalized patients with known or suspected Ebola, which was updated based on feedback from partners who provided care for Ebola patients in the United States. Strengthening and sustaining IPC helps health care systems be better prepared to prevent and respond to current and future infectious disease threats. The activities summarized in this report would not have been possible without collaboration with many U.S. and international partners (http://www.cdc.gov/vhf/ebola/outbreaks/2014-west-africa/partners.html). |
Hepatitis B vaccine stored outside the cold chain setting: a pilot study in rural Lao PDR
Kolwaite AR , Xeuatvongsa A , Ramirez-Gonzalez A , Wannemuehle K , Vongxay V , Vilayvone V , Hennessey K , Patel MK . Vaccine 2016 34 (28) 3324-30 BACKGROUND: Hepatitis B vaccine birth dose (HepB-BD) was introduced in Lao People's Democratic Republic (Lao-PDR) to prevent perinatal hepatitis B virus transmission. HepB-BD, which is labeled for storage between 2 and 8 degrees C, is not available at all health facilities, because of some lack of functional cold chain; however, previous studies show that HepB-BD is stable if stored outside the cold chain (OCC). A pilot study was conducted in Lao-PDR to evaluate impact of OCC policy on HepB-BD coverage. METHODS: During the six month pilot, HepB-BD was stored OCC for up to 28 days in two intervention districts and stored in cold chain in two comparison districts. In the intervention districts, healthcare workers were educated about HepB-BD and OCC storage. A post-pilot survey compared HepB-BD coverage among children born during the pilot (aged 2-8 months) and children born 1 year before (aged 14-20 months). FINDINGS: In the intervention districts, 388 children aged 2-8 months and 371 children aged 14-20 months were enrolled in the survey; in the comparison districts, 190 children aged 2-8 months and 184 children aged 14-20 months were enrolled. Compared with the pre-pilot cohort, a 27% median increase in HepB-BD (interquartile range [IQR] 58%, p<0.0001) occurred in the pilot cohort in the intervention districts, compared with a 0% median change (IQR 25%, p=0.03) in comparison districts. No adverse reactions were reported. INTERPRETATION: OCC storage improved HepB-BD coverage with no increase in adverse reactions. Findings can guide Lao-PDR on implementation and scale-up options of OCC policy. |
Progress toward prevention of transfusion-transmitted hepatitis B and hepatitis C infection - sub-Saharan Africa, 2000-2011
Apata IW , Averhoff F , Pitman J , Bjork A , Yu J , Amin NA , Dhingra N , Kolwaite A , Marfin A . MMWR Morb Mortal Wkly Rep 2014 63 (29) 613-9 Infections with hepatitis B virus (HBV) and hepatitis C virus (HCV) are major causes of morbidity and mortality globally, primarily because of sequelae of chronic liver disease including cirrhosis and hepatocellular carcinoma. The risks for HBV and HCV transmission via blood transfusions have been described previously and are believed to be higher in countries in sub-Saharan Africa. Reducing the risk for transfusion-transmitted human immunodeficiency virus (HIV), HBV, and HCV infection is a priority for international aid organizations, such as the U.S. President's Emergency Plan for AIDS Relief (PEPFAR), the Global Fund to Combat HIV/AIDS, Malaria, and Tuberculosis, and the World Health Organization (WHO). Over the last decade, PEPFAR and the Global Fund have supported blood safety programs in many sub-Saharan African countries with heavy burdens of HIV and acquired immunodeficiency syndrome (AIDS), hepatitis, malaria, and maternal mortality. This report summarizes HBV- and HCV-related surveillance data reported by the blood transfusion services of WHO member states to WHO's Global Database on Blood Safety (GDBS) (4). It also evaluates the performance of blood safety programs in screening for HBV and HCV in 38 sub-Saharan Africa countries.* Selected GDBS indicators were compared for the years 2000 and 2004 (referred to as the 2000/2004 period) and 2010 and 2011 (referred to as the 2010/2011 period). From 2000/2004 to 2010/2011, the median of the annual number of units donated per country increased, the number of countries screening at least 95% of blood donations for HBV and HCV increased, and the median of the national prevalence of HBV and HCV marker-reactive blood donations decreased. These findings suggest that during the past decade, more blood has been donated and screened for HBV and HCV, resulting in a safer blood supply. Investments in blood safety should be continued to further increase the availability and safety of blood products in sub-Saharan Africa. |
Assessing functional needs sheltering in Pike County, Kentucky: using a community assessment for public health emergency response
Kolwaite AR , Hlady WG , Simon MC , Cadwell BL , Daley WR , Fleischauer AT , May Z , Thoroughman D . Disaster Med Public Health Prep 2013 7 (6) 597-602 OBJECTIVE: During 2009-2011, Pike County, Kentucky, experienced a series of severe weather events that resulted in property damage, insufficient potable water, and need for temporary shelters. A Community Assessment for Public Health Emergency Response (CASPER) survey was implemented for future planning. CASPER assesses household health status, preparedness level, and anticipated demand for shelters. METHODS: We used a 2-stage cluster sampling design to randomly select 210 representative households for in-person interviews. We estimated the proportion of households with children aged 2 years or younger; adults aged 65 years or older; and residents with chronic health conditions, visual impairments, physical limitations, and supplemental oxygen requirements. RESULTS: Of all households surveyed, 8% included children aged 2 years or younger, and 27% included adults aged 65 years or older. The most common chronic health conditions were heart disease (51%), diabetes (28%), lung disease (23%), and asthma (21%). Visual impairments were reported in 29% of households, physical limitations in 24%, and supplemental oxygen use in 12%. CONCLUSIONS: Pike County residents should be encouraged to maintain an adequate supply of medications and copies of their prescriptions. Emergency response plans should include transportation for persons with physical limitations; and shelter plans should include sufficient medically trained staff and adequate supplies of infant formula, pharmaceuticals, and supplemental oxygen. |
The role of the GAVI Alliance in improving childhood hepatitis B vaccination in China: successes, lessons learned, and future global challenges
Averhoff F , Kolwaite A , Ward JW . Vaccine 2013 31 Suppl 9 J5-7 China has the world's largest burden of hepatitis B virus (HBV) infection. With an overall prevalence of chronic HBV infection of 7% [1], HBV is a major contributor to morbidity and mortality in China, primarily from cirrhosis and liver cancer [2], [3], [4]. Because transmission during birth and early childhood was contributing substantially to HBV acquisition, China embarked on an aggressive program to implement hepatitis B control through improving rates of vaccination coverage and improving birth dose coverage by leveraging a program to encourage facility-based deliveries. This issue of Vaccine chronicles China's remarkable success in implementing infant and adolescent vaccination programs, promoting safe injection practices, and vaccinating hard to reach populations. This commentary highlights the successful partnership between China's public health authorities and the GAVI Alliance, the GAVI Alliance's contribution to control of hepatitis B globally, and the continued need for GAVI Alliance support to meet the WHO goal of vaccinating all newborns within the first 24 h of life with hepatitis B vaccine. | HBV infection is a major cause of acute and chronic liver disease (e.g., cirrhosis and primary liver cancer) globally and is the sixth leading cause of death from infectious disease worldwide with an estimated 785,000 deaths annually [5]. The World Health Organization (WHO) estimates that a third of the world's population (more than two billion people) have been infected with HBV and that 240 million people are living with chronic HBV infection [6], [7], placing them at risk for serious illness and death from cirrhosis and hepatocellular carcinoma (HCC). Worldwide, 30% of cirrhosis and 53% of all HCC deaths are attributable to HBV infection [3]. In China, HBV prevalence reaches 10% in certain birth cohorts [1]. HBV has taken a heavy toll in China. An estimated 100 million persons are living with chronic HBV infection in China, 350,000 of whom die from HBV-related cirrhosis and liver cancer each year [2], [3], [4]. |
