Background Mobile app-based interventions have been identified as potential facilitators for vaccination among young men who have sex with men (MSM). Objective This pilot study aimed to test the feasibility of a theoretically informed mobile health (mHealth) tool designed to reduce health disparities and facilitate human papillomavirus (HPV) vaccination among a sample of young MSM. Methods The development of the mHealth tool was guided by previous research, implementation intention theory, and design thinking. We recruited MSM aged 18-26 years through a popular online dating app and linked participants to our mHealth tool, which provided HPV vaccine information and fostered access to care. Results A total of 42 young MSM participated in this pilot study in Boston, Massachusetts. Participants reported variable HPV knowledge (ie, high knowledge of HPV risk factors and low knowledge of HPV-related cancer risks for men) and positive vaccine beliefs and attitudes. Of those who were either unvaccinated, not up to date, or did not report vaccine status, 23% (8/35) utilized the mHealth tool to obtain HPV vaccination. Participants primarily utilized the tool’s (1) educational components and (2) capabilities facilitating concrete vaccine action plans. Conclusions We recruited an underserved at-risk population of youth via an online dating app for our mHealth intervention that resulted in in-person health care delivery. This study was limited by enrollment challenges, including low willingness to download the mHealth tool to mobile devices.

The current literature on climate change and mental health impact indicates a significant need for education of health professionals in emergency departments and other health settings. This article contributes strategies to provide an overview of the health consequences of climate change with a focus on mental health impact to increase the awareness of ED providers. Key implications for emergency nursing practice found in this article are that nurses and advanced practice providers play a key role in ensuring timely screening for climate-related mental health impact in vulnerable populations and implement effective interventions to limit the long-term effects caused by the acute psychological trauma as well as chronic psychological trauma associated with the impact of climate change.
