HIV screening among newly diagnosed TB patients: a cross sectional study in Lima, Peru.

Background: Since 2006, the Peruvian National TB program (NTP) recommends voluntary counseling and testing (VCT) for all tuberculosis (TB) patients. Responding to the differential burden of both diseases in Peru, TB is managed in peripheral health facilities while HIV is managed in referral centers. This study aims to determine the coverage of HIV screening among TB patients and the characteristics of persons not screened.

A user-centered model for designing consumer mobile health (mHealth) applications (apps).

Background: Mobile technologies are a useful platform for the delivery of health behavior interventions. Yet little work has been done to create a rigorous and standardized process for the design of mobile health (mHealth) apps. This project sought to explore the use of the Information Systems Research (ISR) framework as guide for the design of mHealth apps.

Using the Information-Motivation-Behavioral Skills Model to Guide the Development of an HIV Prevention Smartphone Application for High-Risk MSM.

HIV remains a significant public health problem among men who have sex with men (MSM). MSM comprise 2% of the U.S.

Implementation of a stepped-wedge cluster randomized design in routine public health practice: design and application for a tuberculosis (TB) household contact study in a high burden area of Lima, Peru.

Background: We designed a pragmatic stepped-wedge cluster randomized controlled trial in order to evaluate provider-initiated evaluation of household contacts (HCs) of smear positive tuberculosis (TB) cases within a routine TB program in Lima, Peru.

Methods/design: National TB program (NTP) officers of San Juan de Lurigancho District (Lima, Peru) and university-based researchers jointly designed a pragmatic stepped-wedge cluster randomized trial design in order to evaluate a planned active case finding (ACF) program for all HCs of smear-positive TB cases in 34 district healthcare centres. Randomization of time to intervention initiation was stratified by health centre TB case rate.

mHealth Technology as a Persuasive Tool for Treatment, Care and Management of Persons Living with HIV.

Mobile health (mHealth) technology can be a valuable tool in the management of chronic illnesses, including HIV. Qualitative research methods were used to identify the desired content and features of a mobile app for meeting and improving the healthcare needs of persons living with HIV (PLWH). We conducted six focus group sessions with 50 English-or Spanish-speaking PLWH in New York City.

Understanding HIV testing behaviors of minority adolescents: a health behavior model analysis.

Adolescents and young adults are the fastest-growing age group of people living with HIV infection in the United States. Yet many adolescents and young adults with high-risk behaviors for HIV are unaware of their HIV status and have never had an HIV test. The purpose of our work was to understand minority adolescents' beliefs, attitudes, and behaviors related to HIV testing.

eHealth interventions for HIV prevention in high-risk men who have sex with men: a systematic review.

Background: While the human immunodeficiency virus (HIV) incidence rate has remained steady in most groups, the overall incidence of HIV among men who have sex with men (MSM) has been steadily increasing in the United States. eHealth is a platform for health behavior change interventions and provides new opportunities for the delivery of HIV prevention messages.

Objective: The purpose of this systematic review was to examine the use of eHealth interventions for HIV prevention in high-risk MSM.

Use of Design Science for Informing the Development of a Mobile App for Persons Living with HIV.

Mobile health (mHealth) technology presents opportunities to enhance chronic illness management, which is especially relevant for persons living with HIV (PLWH). Since mHealth technology comprises evolving and adaptable hardware and software, it provides many challenging design problems. To address this challenge, our methods were guided by the Information System Research (ISR) framework.

Assessment of the Health IT Usability Evaluation Model (Health-ITUEM) for evaluating mobile health (mHealth) technology.

Background: Over two decades of research has been conducted using mobile devices for health related behaviors yet many of these studies lack rigor. There are few evaluation frameworks for assessing the usability of mHealth, which is critical as the use of this technology proliferates. As the development of interventions using mobile technology increase, future work in this domain necessitates the use of a rigorous usability evaluation framework.
