Persistence of Social Norms Feedback on Postsurgery Opioid Prescribing Behavior

This secondary analysis of a randomized clinical trial evaluates the persistence of prescribing guideline-recommended postoperative opioids 1 year after intervention cessation
Randomized Controlled Trial of a Group Cognitive Behavior Therapy HIV Prevention Intervention for Immigrant Latino Gay, Bisexual, and Other Men who Have Sex with Men
Open AccessLaura M Bogart, Joanna L Barreras et al.ARTICLEAIDS and Behavior2025
Latino gay, bisexual, and other men who have sex with men (LGBMSM) are disproportionally affected by HIV in the U.S. We tested a culturally tailored community-based group HIV prevention intervention ("Siempre Seguiré") for immigrant LGBMSM that uses cognitive behavior therapy to address coping with intersectional stigma and medical mistrust. A total of 289 immigrant LGBMSM were randomized (144 control, 145 intervention) and completed surveys at b…
Reducing Bias Among Health Care Providers
Open AccessZachary Wagner, Corrina Moucheraud et al.ARTICLEThe Economic Journal2025References: 2
Bias among health care providers can lead to poor-quality care and poor health outcomes, and it can exacerbate disparities. We use a randomised controlled trial to evaluate an intervention to reduce family planning provider bias towards young women in 227 clinics in Tanzania, Burkina Faso and Pakistan. The intervention educated providers about bias towards young women, facilitated communication about bias with other providers and offered non-fina…

Enhanced Oral Pre-exposure Prophylaxis (PrEP) Implementation for Ugandan Fisherfolk
Open AccessLaura M Bogart, William Musoke et al.ARTICLEAIDS and Behavior2024
Mobile populations such as fisherfolk show high HIV incidence and prevalence. We pilot-tested implementation strategies to enhance pre-exposure prophylaxis (PrEP) uptake and adherence in the context of healthcare outreach events in two mainland fisherfolk communities on Lake Victoria, Uganda from September 2021 to February 2022. The implementation strategies included PrEP adherence supporters (selected from PrEP users' social networks), community…
Contraceptive Care Visit Objectives and Outcomes
Open AccessCorrina Moucheraud, Alexandra Wollum et al.ARTICLEStudies in Family Planning2024References: 42
Globally, care experiences of the growing population of contraceptive users are not well‐understood. We leverage a large client dataset ( n = 71,602) from three countries (Burkina Faso, Pakistan, and Tanzania) to characterize contraceptive services sought (visit objective and method preference), assess whether these visit objectives were met and for whom, and explore if visit objective fulfillment was associated with care quality. Most people in …

A qualitative exploration of health-related present bias among HIV-positive adults in Uganda
Sarah Maccarthy, Alexandra Mendoza-Graf et al.ARTICLEAIDS Care2023
Decision-making errors such as present bias (PB) can have important consequences for health behaviors, but have been largely studied in the financial domain. We conducted a mixed-method study on PB in the context of ART adherence among clinic-enrolled adults in Uganda (n = 39). Specifically, we quantified PB by asking about preferences between medication available sooner to minimize headaches versus available later to cure headaches. We describe …
Food Insecurity During the Covid-19 Pandemic

The role of material deprivations in determining ART adherence
Open AccessUzaib Saya, Zachary Wagner et al.ARTICLEPLOS Global Public Health2022
Despite sustained global scale-up of antiretroviral therapy (ART), adherence to ART remains low. Less than half of those in HIV care in Uganda achieve 85% adherence to their ART medication required for clinically meaningful viral suppression, leaving them at higher risk of transmission. Key barriers to ART adherence include poverty-related structural barriers that are inter-connected and occur simultaneously, making it challenging to examine and …
The cost-effectiveness of community health workers delivering free diarrhoea treatment
Open AccessZachary Wagner, Rushil Zutshi et al.ARTICLEHealth Policy and Planning2022
Community health workers (CHWs) are a vital part of the health infrastructure in Uganda and in many other low- and middle-income countries. While the need for CHWs is clear, it is less clear how they should dispense health products to maximize the health benefits to their community. In this study, we assess the cost-effectiveness of several competing CHW distribution strategies in the context of treatment for child diarrhoea. We used data from a …
The one who doesn’t take ART medication has no wealth at all and no purpose on Earth” – a qualitative assessment of how HIV-positive adults in Uganda understand the health and wealth-related benefits …
Open AccessUzaib Saya, Sarah Maccarthy et al.ARTICLEBMC Public Health2022
PLWH consider short and long-term health benefits of ART. Programming designed to shape ART uptake and increase adherence should emphasize the broader benefits of ART at various levels. Having such benefits directly integrated into the design of clinic-based HIV interventions can be useful especially for PLWH who face competing interests to increase medication adherence. These benefits can ultimately help providers and policymakers better underst…

Assessment of Postoperative Opioid Prescriptions Before and After Implementation of a Mandatory Prescription Drug Monitoring Program
Open AccessRivfka Shenoy, Zachary Wagner et al.ARTICLEJAMA Health Forum2021
In this cross-sectional study, the implementation of mandatory PDMP consultation with a concurrent EHR-based alert was associated with an immediate decrease in opioid prescribing across the 3 surgical specialties. These findings might be explained by prescribers' attempts to meet the mandate exemption and bypass PDMP consultation rather than the PDMP consultation itself. Although policies coupled with EHR alerts may be associated with changes in …

Measuring Family Planning Provider Bias
Open AccessMaria Dieci, Zachary Wagner et al.ARTICLEStudies in Family Planning2021Cited by: 5References: 31
The unmet need for modern contraception remains high around the world, particularly for youth. While some of this unmet need is driven by limited health infrastructure and method mix availability, many adolescents who visit family planning providers still do not receive methods that fit their needs. This suggests that providers may be biased against youth and that interventions to change provider behavior could help close this gap. However, it is…

Open AccessNikhil Sood, Zachary WagnerARTICLEHealth Policy and Planning2013References: 20
Achievement of the health-related Millennium Development Goals is dependent on increasing take-up of preventive public health services (PHSs) in developing countries. Poor country governments often lack the resources to provide optimal access to preventive services and a great deal of attention is being directed towards the private sector to fill this void. In many developing countries, the private sector already plays a large role in health care…
