Effectiveness of the Support From Community Health Workers and Health Care Professionals on the Sustained Use of Wearable Monitoring Devices Among Community-Dwelling Older Adults: Feasibility Randomized Controlled Trial

Effectiveness of the Support From Community Health Workers and Health Care Professionals on the Sustained Use of Wearable Monitoring Devices Among Community-Dwelling Older Adults: Feasibility Randomized Controlled Trial

In this program, feasibility was operationalized through the evaluation of the recruitment rate, attrition rate, incidence of reported adverse events (eg, discomfort, injuries), and incidence of reported technical difficulties (eg, synchronizing data from the WMD to the smartphone app). The recruitment rate was calculated by dividing the number of participants who were recruited and randomized by the number of eligible participants.

Outcomes of a Remotely Delivered Complementary and Integrative Health Partnered Intervention to Improve Chronic Pain and Posttraumatic Stress Disorder Symptoms: Randomized Controlled Trial

Outcomes of a Remotely Delivered Complementary and Integrative Health Partnered Intervention to Improve Chronic Pain and Posttraumatic Stress Disorder Symptoms: Randomized Controlled Trial

The methodology, consent and recruitment process, and baseline attrition have been described in detail elsewhere [9,88]. The study’s methods and results have been reported in accordance with the CONSORT-EHEALTH (Consolidated Standards of Reporting Trials of Electronic and Mobile Health Applications and Online Telehealth) guidelines (Multimedia Appendix 1) [89]. Data were deidentified to protect participants’ identities.

Attrition Rates in HIV Viral Load Monitoring and Factors Associated With Overdue Testing Among Children Within South Africa’s Antiretroviral Treatment Program: Retrospective Descriptive Analysis

Attrition Rates in HIV Viral Load Monitoring and Factors Associated With Overdue Testing Among Children Within South Africa’s Antiretroviral Treatment Program: Retrospective Descriptive Analysis

Although the national Prevention of Mother to Child Transmission program, launched in earnest in 2004, has reduced the vertical transmission rate to approximately 3%, there remain around 280,000 children and adolescents nationwide aged Poor pediatric linkage to care, high attrition rates, and high mortality rates have been described from a number of cohort studies across the country [4-6].

Nudges and Prompts Increase Engagement in Self-Guided Digital Health Treatment for Depression and Anxiety: Results From a 3-Arm Randomized Controlled Trial

Nudges and Prompts Increase Engagement in Self-Guided Digital Health Treatment for Depression and Anxiety: Results From a 3-Arm Randomized Controlled Trial

This pattern was first recognized in 2005 and coined The Law of Attrition [11]. As early as 2009, systematic reviews identified poor adherence and lack of compliance as engagement issues that required attention [12]. These issues persist, as demonstrated by a recent meta-analytic review on digital interventions for depression, which showed efficacy but highlighted compliance as a major challenge [13]. Adherence and compliance are complex and rooted in several systemic and individual factors [14-19].

Designing mHealth Apps to Incorporate Evidence-Based Techniques for Prolonging User Engagement

Designing mHealth Apps to Incorporate Evidence-Based Techniques for Prolonging User Engagement

To fulfill the promise of m Health apps to improve health outcomes, apps need to be improved so they reduce participant attrition. Health care apps do not work for people who do not use them. To date, app feedback, notifications and reminders, in-app support, gamification, and participant compensation have not been consistently successful in eliminating participant dropout.

Patient Engagement With and Perspectives on a Mobile Health Home Spirometry Intervention: Mixed Methods Study

Patient Engagement With and Perspectives on a Mobile Health Home Spirometry Intervention: Mixed Methods Study

In the same meta-analysis, observational real-world studies had even higher (49%) attrition compared to randomized controlled trials. Individual disengagement in RPM programs may arise from a wide range of factors, such as technological difficulties, lack of face-to-face encounters, or irrelevant content [10]. In addition, systemic disparities exist in terms of digital access and literacy, especially among vulnerable populations, leading to inequities in RPM adoption and use [10-13].

Attrition in Conversational Agent–Delivered Mental Health Interventions: Systematic Review and Meta-Analysis

Attrition in Conversational Agent–Delivered Mental Health Interventions: Systematic Review and Meta-Analysis

The overall attrition rate quantifies the level of attrition for the whole sample in a clinical trial, and the differential attrition rate refers to the level of attrition in the intervention group compared with that in the comparison group [26]. Attrition in clinical trials may introduce bias by modifying the random composition of the trial groups, limiting the generalizability of the study, and reducing the study power owing to reduced sample size [13,27].

Evaluating a Remote Monitoring Program for Respiratory Diseases: Prospective Observational Study

Evaluating a Remote Monitoring Program for Respiratory Diseases: Prospective Observational Study

Retention is a crucial metric in mobile health research that provides insights into the duration of participant engagement before attrition. High levels of attrition can pose significant challenges to the feasibility of a study and potentially compromise the validity of its outcomes. Retention can be assessed by calculating the average length of time that participants contribute to data collection before dropping out, which is an essential component of study design and management.
