Preliminary Analysis of Worldwide Usage Patterns in a Mobile Palliative Care Reference App

Abstract

Background: Fast Facts and Concepts for iOS and Android is the world’s most downloaded point of care mobile reference application for palliative care providers. This free mobile app leverages the Fast Facts and Concepts article repository that was started in 1999 at the End-of-Life/Palliative Education Resource Center at the Medical College of Wisconsin. Our team released the initial iOS version of the app in summer of 2014. Since then, it has been downloaded over 13,000 times. Objective: The purpose of this project is to evaluate and describe user behaviors of palliative care clinicians on a global scale using an analytics layer integrated into Fast Facts and Concepts. Methods: An analytics layer was integrated and disclosed with version 1.0.3; an analytics event is triggered when an article is read or when a search is made. The event, along with anonymous user metadata, was sent to a Web server where it was segmented. Summary statistics were generated using Python scripts and include category weight, article rank, and search term clusters. We evaluated user behavior of the Fast Facts and Concepts app during a 3-month window to better understand the needs of the userbase. Results: Our dataset had 26,733 events and 1461 unique users from 41 countries collected over 3 months. Prognosis was the most active category, with searches for Palliative Performance Scale accounting for a third of prognosis reads. Articles about dosage featured heavily, especially on methadone titration. On the spectrum of illness, physiological categories such as gastrointestinal and renal diseases were generally more popular than psychiatric disorders. Articles about interpersonal skills from categories such as Communication; Ethics, Law, Policy; and Psychosocial and Spiritual Experience were the least read. All of our conclusions are supported by chi-squared tests with P values
