ABSTRACT
OBJECT The purpose of this study was to evaluate the clinical effectiveness of telemedicine on changes in body mass index for overweight and obese people as well as for diabetes and hypertension patients. METHODS:
A systematic review of articles published before 31 August 2014, was conducted using searches of Medline, Cochrane Library, EMBASE, and CINAHL Plus. The inclusion criteria were randomised controlled trials that compared telemedicine interventions with usual care or standard treatment in adults and reported a change in body mass index. A meta-analysis was conducted for eligible studies, and the primary outcome was a change in body mass index. Subgroup analysis was performed for the type of telemedicine, main purpose of intervention, and length of intervention.RESULTS:
Twenty-five randomised controlled trials comprising 6253 people were included in the qualitative and quantitative analyses. The length of intervention ranged from nine weeks to two years. The meta-analysis revealed significant differences in body mass index changes (pooled difference in means = -0.49, 95% confidence interval -0.63 to -0.34, p < 0.001) between the telemedicine and control groups. The subgroup analyses found that either Internet-based or telephone-based intervention was associated with greater changes in body mass index than in controls. Telemedicine intervention was effective in improving body mass index whether it was used for diabetes control, hypertension control, weight loss, or increasing physical activity and was also effective for people with and without diabetes or hypertension. However, only interventions with a duration ≥ 6 months significantly decreased body mass index compared to controls.CONCLUSION:
Both patients with chronic disease and overweight/obese people could benefit from telemedicine interventions. We suggest that an effective telemedicine approach should be longer than six months and emphasise the importance of post-interventional follow-ups.Palabras clave
