Mobile health intervention for promotion of eye health literacy

Effect of text messages designed to change contact lens compliance: A randomised controlled trial

PURPOSE

Contact lens behaviours such as poor hand and lens hygiene are common and are associated with increased risk of microbial keratitis. Evidence for health promotion strategies to address this gap is required. The trial examined the effectiveness of a customised text-messaging intervention on compliance, discontinuation rate and wearer satisfaction in contact lens wearers.

METHODS

The parallel group, double masked, randomised clinical trial was pre-registered with the Australian and New Zealand Clinical Trials Registry (ACTRN12621001719820). Contact lens wearers were recruited using social media and optometry partners in clinical practice. Participants (n = 76) received the intervention and usual care. The control group (n = 75) received usual care. Intervention text messages (range 56-76) were customised, provided education, reminders, and motivation and were delivered over six months. Outcomes were validated self-report online surveys for compliance (0-100), satisfaction (0-100) and discontinuation (Y/N), at 3 months and 6 months. Secondary outcomes were intervention feasibility and acceptability.

RESULTS

Participants mean age was 38 years, 105/151 (70 %) female and 83 % completed the trial (intervention 60/76, control 65/75). The intervention group demonstrated better compliance than control with an adjusted between-group-difference at 3 months of 5.2, 95 % confidence interval (CI), 1.6-8.7, P = 0.004 and at 6 months 3.9, 95 % CI 0.2-7.6, P = 0.04. This difference in compliance is clinically significant, equivalent to a single change in a behaviour such as starting to handwash or ceasing overnight wear. There was no adjusted between-group-difference in satisfaction at 3 months (0.8, 95 % CI -4.3-6.0, P = 0.75) or at 6 months (-0.4, 95 % CI -5.7-4.9, P = 0.89). Few participants (7/151, 4.6 %) discontinued contact lens wear (3 intervention, 4 control). The messages were delivered successfully (98 %), at A$11 per participant. Participants reported appropriate message content (75 %), language (80 %) and delivery timing (97 %).

CONCLUSION

This customised text message intervention was a feasible and acceptable method for improving contact lens compliance.

Assessment of Eye Care Apps for Children and Adolescents Based on the Mobile App Rating Scale: Content Analysis and Quality Assessment

BACKGROUND

In China, the current situation of myopia among children and adolescents is very serious. Prevention and control of myopia are inhibited by the lack of medical resources and the low awareness about eye care. Nevertheless, mobile apps provide an effective means to solve these problems. Since the health app market in China is still immature, it has become particularly important to conduct a study to assess the quality of eye-care apps to facilitate the development of better eye-care service strategies.

OBJECTIVE

This study aimed to evaluate the quality, functionality, medical evidence, and professional background of eye-care apps targeting children and adolescents in the Chinese app stores.

METHODS

A systematic search on iOS and Android app stores was performed to identify eye-care apps for children and adolescents. The general characteristics, development context, and functional features of the apps were described. Quality assessment of the apps was completed by 2 independent researchers using the Mobile App Rating Scale.

RESULTS

This study included 29 apps, of which 17 (59%) were developed by commercial organizations and 12 (41%) had a design with relevant scientific basis. The main built-in functions of these apps include self-testing (18/29, 62%), eye exercises (16/29, 55%), and eye-care education (16/29, 55%). The mean overall quality of eye-care apps was 3.49 (SD 0.33), with a score ranging from 2.89 to 4.39. The overall Mobile App Rating Scale score exhibited a significant positive correlation with the subscale scores (r=0.81-0.91; P<.001). In addition, although most apps provided basic eye-care features, there are some deficiencies. For example, only a few apps were developed with the participation of medical organizations or professional ophthalmologists, and most of the apps were updated infrequently, failing to provide the latest eye-care information and technology in a timely manner.

CONCLUSIONS

In general, the quality of eye-care apps for children and teenagers in Chinese app stores is good. These apps fulfill users' needs for eye-care services to a certain extent, but they still suffer from insufficient medical background, low user engagement, and untimely updates. In order to further improve the effectiveness of eye-care apps, cooperation with medical institutions and professional ophthalmologists should be strengthened to enhance the scientific and authoritative nature of the apps. At the same time, interactive features and regular updates should be added to enhance user participation and the continuity of the apps. This study provides a reference for future development or improvement of eye-care apps, which can help promote myopia prevention and control.

Assessing the capacity of primary health care facilities in Nigeria to deliver eye health promotion: Results of a mixed-methods feasibility study

Over 25 million people in sub-Saharan Africa are blind or visually impaired, the majority from avoidable causes. Health promotion and disease prevention are important strategies for eye health, through good governance, health literacy and increasing access to eye care services. To increase equity in access for eyecare services, the World Health Organization Africa Region developed a package of interventions for primary eye care, which includes health promotion. The aim of this study was to assess the capacity of the primary healthcare system to deliver health promotion for eye care in Nigeria. Mixed methods were used during a survey of 48 government-owned primary health care facilities in Anambra state, Nigeria: interviews with district health supervisors, facility staff and village health workers, and a desk review of policy documents for primary health care and eye care in Nigeria. Findings were benchmarked against the capacities needed to deliver health promotion agreed through a Delphi exercise and were analysed using the World Health Organization's health system building blocks. Eye health promotion policies exist but are fragmented across different national health policies. Health promotion activities focussed on "mobilising" community members to access care provided in facilities, particularly for women of childbearing age and young children, and health education was limited. Only one in ten facilities engaged the elderly and a fifth delivered health promotion for eye care. Health promotion activities were supervised in 43.2% of facilities and transport to remote areas was limited. A robust eye health promotion strategy needs to be included in the National Eye Health Policy. The scope of existing health promotion will need to expand to include eye conditions and different age groups. Increasing eye health literacy should be emphasized. Governance, training health workers in eye health promotion, educational materials, and transport to visit communities will also be needed.
