Does Mobile Care ('mCare') Improve Quality of Life and Treatment Satisfaction Among Service Members Rehabilitating in the Community? Results from a 36-Wk, Randomized Controlled Trial

Abstract

Introduction: Research has shown that mobile phones can help with management of numerous health problems. As an adjunct to care management provided to injured service members rehabilitating in their communities, particularly those with mild traumatic brain injury (mTBI), post-traumatic stress (PTS), and/or behavioral health problems, the Army developed a mobile phone application called "mCare." This study examined whether service members who received mCare had higher well-being, were more satisfied with their care, and viewed mCare as a valuable part of their care management as compared with their counterparts who received standard care management alone, and whether those with mTBI, PTS, and/or behavioral health problems benefited differently from mCare.

Materials and methods: In-processing service members at four community-based warrior transition units were recruited for participation in a 36-wk, randomized, controlled trial and allocated to receive standard care management plus mCare (n = 95) or standard care management alone (n = 87). Participants in the mCare group received daily questionnaires, tips, and appointment reminders. All participants were asked to complete the General Well-being Schedule (GWS) at baseline, 12, 24, and 36 wk, and the Case Management Quality Questionnaire (CMQQ) at 12, 24, and 36 wk. All participants and care managers were approached to complete interviews about the usability/likeability of mCare or standard care management. The analyses tested for group differences in completion of the intervention, graphed means for the GWS and CMQQ by group/subgroup, and statistically compared the longitudinal trends in these outcomes using mixed models in which group, time, and group*time were included as regression variables. The analyses also tallied interview responses and identified thematic quotes. The study protocol was reviewed and approved by the Walter Reed National Military Medical Center's Institutional Review Board.

Results: Estimated rate of change in GWS scores was -2.2 (standard error = 1.0; t = -2.1; p = 0.0382). Estimated rate of change in CMQQ scores was -0.8 (standard error = 0.5; t = -1.52; p = 0.1299). Neither change was meaningful. Rates of change in the GWS and CMQQ scores did not differ by group or by behavioral health, mTBI, and PTS subgroups within the groups. The interviews found that 83% of mCare participants liked the communication with their care managers versus 73% of standard care management participants. Participants in both the mCare group and the care managers said that they liked the application's appointment tracking and reminders. Care managers thought mCare was particularly useful for people with mTBI, PTS, and cognitive problems.

Conclusion: mCare did not result in differences in general well-being and satisfaction with care management among service members rehabilitating in their communities, some with mTBI, PTS, and/or behavioral health problems. But participants and care managers who used mCare said that they found it useful. Study limitations included the diversity of clinical issues of the participants, greater missing data among mCare participants, and the high baseline quality of care management in the settings observed. The fact that patients and care managers liked mCare, apart from no changes in outcomes, is important because health care is increasingly adopting mobile solutions.
