Measuring Success of Patients’ Continuous Use of Mobile Health Services for Self-management of Chronic Conditions: Model Development and Validation

Abstract

Background Mobile health services are gradually being introduced to support patients’ self-management of chronic conditions. The success of these services is contingent upon patients’ continuous use of them. Objective This study aims to develop a model to measure the success of patients’ continuous use of mobile health services for the self-management of chronic conditions. Methods The proposed model was derived from the information systems continuance model and the information systems success model. This model contains 7 theoretical constructs: information quality, system quality, service quality, perceived usefulness, user satisfaction, perceived health status, and continuous use intention. A web-based questionnaire survey instrument was developed to test the model. The survey was conducted to collect data from 129 patients who used a mobile health app for hypertension management from 2017 to 2019. The questionnaire items were derived from validated instruments and were measured using a 5-point Likert scale. The partial least squares modelling method was used to test the theoretical model. Results The model accounted for 58.5% of the variance in perceived usefulness (R2=0.585), 52.3% of the variance in user satisfaction (R2=0.523), and 41.4% of the variance in patients’ intention to make continuous use of mobile health services (R2=0.414). The continuous use intention was significantly influenced by their perceived health status (β=.195, P=.03), perceived usefulness (β=.307, P=.004), and user satisfaction (β=.254, P=.04) with the mobile health service. Information quality (β=.235, P=.005), system quality (β=.192, P=.02), and service quality (β=.494, P<.001) had a significantly positive influence on perceived usefulness but not on user satisfaction. Perceived usefulness had a significantly positive influence on user satisfaction (β=.664, P<.001). In a result opposite to the original hypothesis, perceived health status did not negatively influence patients’ intention to continue using the mobile health service but showed a significantly positive correlation. Conclusions This study developed a theoretical model to predict and explain patients’ continuous use of mobile health services for self-management of chronic conditions and empirically tested the model. Perceived usefulness, user satisfaction, and health status contributed to patients’ intention to make continuous use of mobile health services for self-managing their chronic conditions.

Effectiveness of mobile health‐based self‐management application for posttransplant cares: A systematic review

“… 12 , 13 m‐Health to support patients with chronic diseases in self‐management has been widely considered in the last decade. 14 , 15 WHO defines m‐Health as a medical and public health approach supported by mobile devices, patient monitoring devices, personal digital assistants (PDAs), and other wireless devices. 2 Statista website shows that the m‐Health market is growing and projected to exceed US$ 300 billion by 2025.…”

“…m‐Health applications facilitate communication between patients and treatment staff, reduce chronic diseases costs, adhere to medical regimens, and influence patient outcomes. 14 , 17 , 18 …”

“…m-Health applications facilitate communication between patients and treatment staff, reduce chronic diseases costs, adhere to medical regimens, and influence patient outcomes. 14,17,18 Due to the increasing popularity of m-Health, some studies have reported the effect of m-Health interventions on chronic diseases; for example, Fan and Zhao examined the effect of m-Health on the outcomes of patients with chronic diseases and its limitations. This study showed a positive trend in m-Health interventions for the management of chronic diseases.…”

Effects of Mobile Application Program (App)-Assisted Health Education on Preventive Behaviors and Cancer Literacy among Women with Cervical Intraepithelial Neoplasia

“…Mobile health services are a supportive technique that has gradually been introduced to support patients in their self-management of chronic disorders, such as hypertension [ 10 ], cardiovascular diseases [ 11 ], diabetes [ 12 ], and obesity [ 13 ], and even improve patients’ medication adherence [ 14 ]. Recently, some smartphone apps were designed to address the COVID-19 pandemic [ 15 ], while an evidence-based mobile health (mHealth) program led to significant reductions in depressive symptoms [ 16 ].…”

Effects of Patient-Generated Health Data: Comparison of Two Versions of Long-Term Mobile Personal Health Record Usage Logs

“…To fully utilize the collected information, inducing long-term usage by the user is needed. Only a handful of previous studies focused on the continued use of mPHR services [ 13 , 14 , 15 , 16 ]. One study reported that it is important for mobile app users to frequently enter data into the app to monitor health-related behaviors for effective weight loss, regardless of the region and app version [ 14 ].…”
