INTRODUCTION

Gay social networking apps have grown in popularity among men who have sex with men offering opportunities for rapid and confidential collection of vital data as well as social connection. The goal of our study was to explore factors associated with utilization of pre-exposure prophylaxis (PrEP) and antiretroviral treatment (ART), and self-reported undetectable viral load (UVL) using data collected by the gay social networking app Hornet.

METHODS

In 2016, the Global Forum on MSM & HIV (MSMGF) partnered with Hornet, to support an educational initiative called Blue-Ribbon Boys. One aspect of the initiative prompts Hornet users to answer a short series of yes-no questions about their sexual health. Using survey responses, we evaluated factors associated with PrEP and ART use as well as self-reported UVL by fitting separate multivariable generalized estimating equation models.

RESULTS

In total, 16,008 unique Hornet users started the survey, of which 12,126 (76%) provided sufficient data for analyses. Of the 10,774 HIV-negative men, 13% reported PrEP use in the past year. PrEP use was associated with a recent sexually transmitted infection (STI) test or treatment (aOR = 2.19, CI = 1.49 to 3.21); and taking steps to protect oneself from HIV (aOR = 1.41, CI = 1.13 to 1.76). Among HIV-positive Hornet users (n = 1243), ART use was associated with older age (each year increase aOR = 1.02, CI = 1.01 to 1.04), a recent STI test or treatment (aOR = 4.54, CI = 2.65 to 7.78); and awareness of unlikely HIV transmission with UVL (aOR = 1.53, CI = 1.03 to 2.26). UVL was associated with older age (each year increase aOR = 1.03, CI = 1.01 to 1.04), a recent STI test or treatment (aOR = 4.84, CI = 2.74 to 8.55), and awareness of unlikely HIV transmission with UVL (aOR = 1.98, CI = 1.37 to 2.85).

CONCLUSIONS

Study findings underscore the importance of STI testing and treatment as well as information about HIV transmissibility for encouraging PrEP and ART use. Our findings also reveal age disparities, which can undermine incidence reduction among gay men. Gay social networking apps can be effectively used for rapid data collection and sexual health promotion with men who have sex with men. STI testing and treatment programmes offer important opportunities for encouraging PrEP and ART use. Information about HIV transmissibility with consistent ART use should be incorporated into prevention messaging tailored to various age groups.

BACKGROUND

New models of patient-centered primary care such as the patient-centered medical home (PCMH) depend on high levels of interdisciplinary primary care team functioning to achieve improved outcomes. A few studies have qualitatively assessed barriers and facilitators to optimal team functioning; however, we know of no prior study that assesses PCMH team functioning in relationship to patient health outcomes.

PURPOSE

The aim of the study was to assess the relationships between primary care team functioning, patients' use of acute care, and mortality.

METHODOLOGY/APPROACH

Retrospective longitudinal cohort analysis of patient outcomes measured at two time points (2012 and 2013) after PCMH implementation began in Veterans Health Administration practices. Multilevel models examined practice-level measures of team functioning in relationship to patient outcomes (all-cause and ambulatory care-sensitive condition-related hospitalizations, emergency department visits, and mortality). We controlled for practice-level factors likely to affect team functioning, including leadership support, provider and staff burnout, and staffing sufficiency, as well as for individual patient characteristics. We also tested the model among a subgroup of vulnerable patients (homeless, mentally ill, or with dementia).

RESULTS

In adjusted analyses, higher team functioning was associated with lower mortality (OR = 0.92, p = .04) among all patients and with fewer all-cause admissions (incidence rate ratio [IRR] = 0.90, p < 0.01), ambulatory care-sensitive condition-related admissions (IRR = 0.91, p = .04), and emergency department visits (IRR = 0.91, p = .03) in the vulnerable patient subgroup.

CONCLUSION

These early findings give support for the importance of team functioning within PCMH models for achieving improved patient outcomes.

PRACTICE IMPLICATIONS

A focus on team functioning is important especially in the early implementation of team-based primary care models.
