J Water Sanit Hyg Develop 2023 13 (10) 847-856 In response to the COVID-19 pandemic, we established and sustained local production of Alcohol-Based Hand Rub (ABHR) at a district scale for healthcare facilities and community, public locations in four districts in Uganda. District officials provided space and staff for production units. The project renovated space for production, trained staff on ABHR production, and transported ABHR to key locations. The production officer conducted internal ABHR quality assessments while trained district health inspectors conducted external quality assessments prior to distribution. Information, education, and communication materials accompanied ABHR distribution. Onsite ABHR consumption was moni-tored by site staff using stock cards. On average, it took 11 days (range: 8–14) and 5,760 USD (range: 4,400–7,710) to setup a production unit. From March to December 2021, 21,600 L of quality-controlled ABHR were produced for 111 healthcare facilities and community locations at an average cost of 4.30 USD/L (range: 3.50–5.76). All ABHR passed both internal and external quality control (average ethanol concentration of 80%, range: 78–81%). This case study demonstrated that establishing centralized, local production of quality-controlled, affordable ABHR at a district-wide scale is feasible and strengthens the ability of healthcare workers and community locations to access and use ABHR during infectious disease outbreaks in low-resource countries. © 2023 The Authors. |

PLOS Water 2022 1 (6) Continuity of key water, sanitation, and hygiene (WASH) infrastructure and WASH practices-for example, hand hygiene-are among several critical community preventive and mitigation measures to reduce transmission of infectious diseases, including COVID-19 and other respiratory diseases. WASH guidance for COVID-19 prevention may combine existing WASH standards and new COVID-19 guidance. Many existing WASH tools can also be modified for targeted WASH assessments during the COVID-19 pandemic. We partnered with local organizations to develop and deploy tools to assess WASH conditions and practices and subsequently implement, monitor, and evaluate WASH interventions to mitigate COVID-19 in low- and middle-income countries in Latin America and the Caribbean and Africa, focusing on healthcare, community institution, and household settings and hand hygiene specifically. Employing mixed-methods assessments, we observed gaps in access to hand hygiene materials specifically despite most of those settings having access to improved, often onsite, water supplies. Across countries, adherence to hand hygiene among healthcare providers was about twice as high after patient contact compared to before patient contact. Poor or non-existent management of handwashing stations and alcohol-based hand rub (ABHR) was common, especially in community institutions. Markets and points of entry (internal or external border crossings) represent congregation spaces, critical for COVID-19 mitigation, where globally-recognized WASH standards are needed. Development, evaluation, deployment, and refinement of new and existing standards can help ensure WASH aspects of community mitigation efforts that remain accessible and functional to enable inclusive preventive behaviors. |
Direct-reading instruments for aerosols: A review for occupational health and safety professionals part 1: Instruments and good practices
Vosburgh DJH , Cauda E , O'Shaughnessy PT , Sheehan MJ , Park JH , Anderson K . J Occup Environ Hyg 2022 19 (12) 1-16 With advances in technology, there are an increasing number of direct-reading instruments available to occupational health and safety professionals to evaluate occupational aerosol exposures. Despite the wide array of direct-reading instruments available to professionals, adoption of direct-reading technology to monitor workplace exposures has been limited, partly due to a lack of knowledge on how the instruments operate, how to select an appropriate instrument, and challenges in data analysis techniques. This paper presents a review of direct-reading aerosol instruments available to occupational health and safety professionals, describes the principles of operation, provides guidance on instrument selection based on the workplace and exposure, and discusses data analysis techniques in an effort to overcome these barriers to adoption. This paper does not cover all direct-reading instruments for aerosols but only those that an occupational health and safety professional could use in a workplace to evaluate exposures. Therefore, this paper focuses on instruments that have the most potential for workplace use due to their robustness, past workplace use, and price with regards to return on investment. The instruments covered in this paper include those that measure aerosol number concentration, mass concentration and aerosol size distributions. |
Are couple-based interventions more effective than interventions delivered to individuals in promoting HIV protective behaviors? a meta-analysis
Crepaz N , Tungol-Ashmon MV , Vosburgh HW , Baack BN , Mullins MM . AIDS Care 2015 27 (11) 1-6 Despite several advantages to bringing couples together to learn how to protect themselves and new-born children from the risk of HIV infection, most interventions are designed for individuals or groups, not for dyads. This meta-analysis provides a direct test of whether couple-based interventions are more effective in promoting HIV protective behaviors than interventions delivered to individuals. We conducted systematic searches of five electronic databases and 60 journals. Eligible studies were controlled trials or prospective cohort designs; evaluated a couple-based intervention compared to an individual-level intervention; assessed at least one HIV prevention outcome (e.g., protective sex, drug use, HIV testing, medication adherence, and sexually transmitted infections [STI]); and were published between 1988 and 2014. Fifteen interventions, including 21,882 participants from China, Kenya, Rwanda, Tanzania, Trinidad, Zambia, and the USA, were evaluated. The results of random-effects models showed statistically significant intervention effects for protective sex (OR = 1.60, 95% CI = 1.21, 2.11), HIV testing (OR = 1.79, 95% CI = 1.31, 2.45), and Nevirapine uptake (OR = 1.51, 95% CI = 1.02, 2.24). The evidence demonstrates the usefulness of couple-based interventions in protecting individuals, partners, and new-born children from the risk of HIV transmission and infection. |
Evaluation of a diffusion charger for measuring aerosols in a workplace
Vosburgh DJ , Ku BK , Peters TM . Ann Occup Hyg 2014 58 (4) 424-36 The model DC2000CE diffusion charger from EcoChem Analytics (League City, TX, USA) has the potential to be of considerable use to measure airborne surface area concentrations of nanoparticles in the workplace. The detection efficiency of the DC2000CE to reference instruments was determined with monodispersed spherical particles from 54 to 565.7nm. Surface area concentrations measured by a DC2000CE were then compared to measured and detection efficiency adjusted reference surface area concentrations for polydispersed aerosols (propylene torch exhaust, incense, diesel exhaust, and Arizona road dust) over a range of particle sizes that may be encountered in a workplace. The ratio of surface area concentrations measured by the DC2000CE to that measured with the reference instruments for unimodal and multimodal aerosols ranged from 0.02 to 0.52. The ratios for detection efficiency adjusted unimodal and multimodal surface area concentrations were closer to unity (0.93-1.19) for aerosols where the majority of the surface area was within the size range of particles used to create the correction. A detection efficiency that includes the entire size range of the DC2000CE is needed before a calibration correction for the DC2000CE can be created. For diesel exhaust, the DC2000CE retained a linear response compared to reference instruments up to 2500mm(2) m(-3), which was greater than the maximum range stated by the manufacturer (1000mm(2) m(-3)). Physical limitations with regard to DC2000CE orientation, movement, and vibration were identified. Vibrating the DC2000CE while measuring aerosol concentrations may cause an increase of ~35mm(2) m(-3), whereas moving the DC2000CE may cause concentrations to be inflated by as much as 400mm(2) m(-3). Depending on the concentration of the aerosol of interest being measured, moving or vibrating a DC2000CE while measuring the aerosol should be avoided. |
A systematic review of interventions for reducing HIV risk behaviors among people living with HIV in the United States, 1988-2012
Crepaz N , Tungol-Ashmon MV , Higa DH , Vosburgh W , Mullins MM , Barham T , Adegbite A , DeLuca JB , Sipe TA , White CM , Baack BN , Lyles CM . AIDS 2014 28 (5) 633-656 OBJECTIVE: To conduct a systematic review to examine interventions for reducing HIV risk behaviors among people living with HIV (PLWH) in the United States. METHODS: Systematic searches included electronic databases from 1988 to 2012, hand searches of journals, reference lists of articles, and HIV/AIDS Internet listservs. Each eligible study was evaluated against the established criteria on study design, implementation, analysis, and strength of findings to assess the risk of bias and intervention effects. RESULTS: Forty-eight studies were evaluated. Fourteen studies (29%) with both low risk of bias and significant positive intervention effects in reducing HIV transmission risk behaviors were classified as evidence-based interventions (EBIs). Thirty-four studies were classified as non-EBIs due to high risk of bias or nonsignificant positive intervention effects. EBIs varied in delivery from brief prevention messages to intensive multisession interventions. The key components of EBIs included addressing HIV risk reduction behaviors, motivation for behavioral change, misconception about HIV, and issues related to mental health, medication adherence, and HIV transmission risk behavior. CONCLUSION: Moving evidence-based prevention for PLWH into practice is an important step in making a greater impact on the HIV epidemic. Efficacious EBIs can serve as model programs for providers in healthcare and nonhealthcare settings looking to implement evidence-based HIV prevention. Clinics and public health agencies at the state, local, and federal levels can use the results of this review as a resource when making decisions that meet the needs of PLWH to achieve the greatest impact on the HIV epidemic. |
A systematic review to identify challenges of demonstrating efficacy of HIV behavioral interventions for gay, bisexual, and other men who have sex with men (MSM)
Higa DH , Crepaz N , Marshall KJ , Kay L , Vosburgh HW , Spikes P , Lyles CM , Purcell DW . AIDS Behav 2013 17 (4) 1231-44 Gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by HIV but few MSM-specific evidence-based interventions (EBIs) have been identified for this vulnerable group. We conducted a systematic review to identify reasons for the small number of EBIs for MSM. We also compared study, intervention and sample characteristics of EBIs versus non-EBIs to better understand the challenges of demonstrating efficacy evidence. Thirty-three MSM-specific studies were evaluated: Nine (27 %) were considered EBIs while 24 (73 %) were non-EBIs. Non-EBIs had multiple methodological limitations; the most common was not finding a significant positive effect. Compared to EBIs, non-EBIs were less likely to use peer intervention deliverers, include sexual communication in their interventions, and intervene at the community level. Incorporating characteristics associated with EBIs may strengthen behavioral interventions for MSM. More EBIs are needed for substance-using MSM, MSM of color, MSM residing in the south and MSM in couples. |
A review of the literature on event-level substance use and sexual risk behavior among men who have sex with men
Vosburgh HW , Mansergh G , Sullivan PS , Purcell DW . AIDS Behav 2012 16 (6) 1394-410 In the United States, there continues to be high incidence of HIV infection among men who have sex with men (MSM), who represent 57% of new infections in 2009. While many studies report associations between non-injection substance use and sexual risk behavior among MSM, overall results are mixed. Summarizing these studies is difficult because researchers have used a variety of assessment periods for substance use and sexual behavior. We review the scientific literature on event-level measures, which assess substance use and sexual risk behavior immediately before or during a sexual encounter and provide the most precise link between these two behaviors. From January 2009 through March 2010, we searched four databases: Ovid (MEDLINE and PsycINFO), Web of Knowledge, and Sociofile. Across studies, results varied by substance with little within substance consistency or a lack of research except for two notable exceptions: methamphetamine and binge alcohol use. The findings underscore the importance of providing HIV risk-reduction interventions for substance-using MSM. |
