Effect of a Mobile Health Application With Nurse Support on Quality of Life Among Community-Dwelling Older Adults in Hong Kong

Abstract

ImportanceMobile health (mHealth) smartphone apps are becoming increasingly popular among older adults, although the reactive care approach of these apps has limited their usability.ObjectiveTo evaluate the effects of an interactive mHealth program supported by a health-social partnership team on quality of life (QOL) among community-dwelling older adults in Hong Kong.Design, Setting, and ParticipantsThis was a 3-group, randomized clinical trial conducted in 5 community centers in Hong Kong from December 1, 2020, to April 30, 2022, with a last follow-up date of January 31, 2022. Participants included older adults aged at least 60 years who were living within the service area, used a smartphone, and had at least 1 of the following problems: chronic pain, hypertension, or diabetes. Data were analyzed from May 1 to 10, 2022.InterventionsParticipants were randomly assigned to the mHealth with interactivity (mHealth+I) group, mHealth group, or control group. Participants in the mHealth+I group received the mHealth app and nurse case management supported by a health-social partnership team. The mHealth group received the mHealth app only. The control group received no mHealth app or health-social care services.Main Outcomes and MeasuresThe primary outcome was the change in QOL from baseline to 3 months after completion of the intervention.ResultsAmong 221 participants (mean [SD] age 76.6 [8.0] years; 185 [83.7%] women), 76 were randomized to the control group, 71 were randomized to the mHealth group, and 74 were randomized to the mHealth+I group. The most common chronic diseases or problems were hypertension (147 participants [66.5%]), pain (144 participants [65.2%]), cataracts (72 participants [32.6%]), and diabetes (61 participants [27.6%]). At 3 months after the intervention and compared with the intervention group, there were no statistically significant differences in either the physical component summary (mHealth+I: β = −1.01 [95% CI, −4.13 to 2.11]; P = .53; mHealth: β = 0.22 [95% CI, −3.07 to 3.50]; P = .90) or the mental component summary (mHealth+I: β = −0.87 [95% CI, −4.42 to 2.69]; P = .63; mHealth: β = 1.73 [95% CI, −1.89 to 5.34]; P = .35) QOL scores. Only secondary outcomes, including self-efficacy (β = −2.31 [95% CI, −4.26 to −0.36]; P = .02), systolic blood pressure (β = −2.30 [95% CI, −5.00 to −0.13]; P = .04), pain levels (β = 1.18 [95% CI, 0.52 to 2.00]; P = .02), and health services utilization (β = 0.98 [95% CI, 0.32 to 2.09]; P = .048) improved in the mHealth+I group compared with the control group.Conclusions and RelevanceThis randomized clinical trial found no difference in the primary outcome between the mHealth+I group and the control group confirming that there were no incremental benefits to adding interactivity in mHealth programs for older adults with chronic diseases.Trial RegistrationClinicaltrials.gov Identifier: NCT03878212

Interventions of eHealth technologies integrated with non-physician health workers for improving management of hypertension: Systematic review and meta-analysis

“…The majority of studies were undertaken in the USA (5 studies) [17][18][19][20][21] , followed by China (3 studies) [22][23][24][25] . Other countries included Argentina [26] , Bangaladesh [27] , India [23,28] , South Korea [29] , Ghana [30] , Kenya [31] , Sweden [32] , Australia [33] , Jordan [34] , and Canada [35] .…”

Technology: A metaparadigm concept of nursing

“…New models of care are emerging to improve patient and family outcomes. Now more than ever, patients and community‐dwelling older adults are being empowered to partner with various advanced and low‐end technological applications to self‐manage even in the absence of a healthcare provider (Vaffis et al, 2023; Wong, Bayuo, Wong, Chow, et al, 2023; Wong, Wong, Bayuo, et al, 2022; Wong, Wong, Chow, et al, 2022).…”

“…The metaverse also offers a virtual environment enabled by technology to train nurses (De Gagne et al, 2022). In the communities, nurses continue to employ internet‐based resources and mobile health (mHealth) applications to promote the delivery of person‐centred care across varied population groups such as community‐dwelling older adults (Wong, Bayuo, et al, 2022; Wong, Bayuo, Wong, Chow et al, 2023; Wong, Wong, Bayuo et al, 2022; Wong, Wong, Chow, et al, 2022) and stroke survivors (Burns et al, 2021; Wong, Bayuo, Wong, Kwok, et al, 2023). In fact, as the world battled with the Coronavirus pandemic, these technologies were shown to be the ‘game changers’ in healthcare (Betriana et al, 2022).…”

Nurse-led self-care interventions for older adults with multiple chronic conditions: A protocol for a systematic review and network meta-analysis

“…Nurses have various roles in nurse-led interventions, including coordinators, case managers, consultants, educators, navigators, practitioners, and researchers [ 24 , 31 – 33 ]. Current evidence supports the positive impact of nurse-led interventions on managing chronic diseases, including systolic blood pressure, pain control, and health services utilization [ 11 , 34 , 35 ].…”
