Patient and public involvement in mobile health-based research for hay fever: a qualitative study of patient and public involvement implementation process.

ABSTRACT

BACKGROUND: Smartphones are being increasingly used for research owing to their multifunctionality and flexibility, and crowdsourced research using smartphone applications (apps) is effective in the early detection and management of chronic diseases. We developed the AllerSearch app to gather real-world data on individual subjective symptoms and lifestyle factors related to hay fever. This study established a foundation for interactive research by adopting novel, diverse perspectives accrued through implementing the principles of patient and public involvement (PPI) in the development of our app. METHODS: Patients and members of the public with a history or family history of hay fever were recruited from November 2019 to December 2021 through a dedicated website, social networking services, and web briefing according to the PPI Guidebook 2019 by the Japan Agency for Medical Research and Development. Nine opinion exchange meetings were held from February 2020 to December 2021 to collect opinions and suggestions for updating the app. After each meeting, interactive evaluations from PPI contributors and researchers were collected. The compiled suggestions were then incorporated into the app, establishing an active feedback loop fed by the consistently interactive infrastructure. RESULTS: Four PPI contributors (one man and three women) were recruited, and 93 items were added/changed in the in-app survey questionnaire in accordance with discussions from the exchange meetings. The exchange meetings emphasized an atmosphere and opportunity for participants to speak up, ensuring frequent opportunities for them to contribute to the research. In March 2020, a public website was created to display real-time outcomes of the number of participants and users' hay-fever-preventative behaviors. In August 2020, a new PPI-implemented AllerSearch app was released. CONCLUSIONS: This study marks the first research on clinical smartphone apps for hay fever in Japan that implements PPI throughout its timeline from research and development to the publication of research results. Taking advantage of the distinct perspectives offered by PPI contributors, a step was taken toward actualizing a foundation for an interactive research environment. These results should promote future PPI research and foster the establishment of a social construct that enables PPI efforts in various fields.

Patient and public involvement (PPI) plays an important role in promoting effective execution of health science research, as well as in the establishment of a social agreement and infrastructure for the care of various diseases, including cancer, chronic diseases, and allergic illnesses. Hay fever is one of the most common allergic diseases, affecting more than 30 million people in Japan. It is known for its myriad factors and diverse presentations. Previously, we developed a mobile health (mHealth) smartphone application (app) for hay fever­AllerSearch­released in February 2018. This app is capable of collecting relevant digital phenotypes and user-provided information, which are used in providing tailored, evidence-based suggestions. To our knowledge, no other studies have been conducted on the implementation of PPI in mHealth. Since hay fever presents with a wide variety of symptoms and risk factors, PPI principles appear well-suited for eliciting insights from the patient/public population and for incorporating new, expert perspectives into the research process. In this study, we included PPI contributors in the research plan, app development, and evaluation. Most notably, the survey questionnaire and user interface of the app was tailored based on PPI feedback. The updated AllerSearch app was released during this study period. Since hay fever is a widespread and variable illness, the multifaceted input from patients and public experts enabled by PPI implementation holds promise for improving society-wide healthcare and in empowering a culture toward medical involvement.
