Cost-Effectiveness of Mobile Application Use in Managing Type 2 Diabetes Mellitus: A Systematic Review Introduction Type 2 diabetes mellitus (T2DM) is a debilitating condition that imposes a significant economic burden on its management. This study aims to systematically review the published evidence on the cost-effectiveness of mobile health (mHealth) application interventions for T2DM. Methods A search strategy was conducted using electronic bibliographic databases, including PubMed, Web of Science and Scopus for published studies. The inclusion criteria included original articles that reporting cost-effectiveness evaluation studies on mHealth application interventions directed at patients diagnosed or at risk of T2DM, English-language articles and published in the year 2016 to 2020. Results A total of 6 eligible studies were selected. The cost savings per person for treating T2DM ranged from USD 1,346 to USD 3,781 per year. The major contributor to cost savings was reduced complication management resulting from good glycaemic control. The direct impacts of the intervention include reduced hospitalisation and fewer unplanned clinic visits, while diabetes- related mortality was indirectly reduced usingmHealth. Conclusions The mHealth intervention was cost-effective in managing patients with T2DM. Implementation can be extended to other disease management areas to not only reduce total healthcare expenditure but also improve patients’ quality of life.

Environmental Determinants in Sustaining the Transmission of Lymphatic Filariasis: A Systematic Review IntroductionSince mass drug administration continues in many of the endemic countries, it is vital to synthesise evidence to adapt the challenges contributed by the environments. As such, the aim of this review was to explore relationship between lymphatic filariasis prevalence and potential environmental determinants .MethodsWe searched the electronic databases PubMed, Web of Science, Cochrane, and Scopus between Jan 1, 2013, and Dec 31, 2022, for studies fulfilling the following criteria: it was an original article investigating the environmental determinants associated with transmission of lymphatic filariasis; and the study was published in English. The quality assessment tools for observational studies from the National Heart, Lung, and Blood Institute was used to assess the study quality. This systematic review was registered with the PROSPERO database (CRD42023393018).ResultsWe identified 409 potentially eligible published articles, of which 11 met our inclusion criteria. The main environmental determinants associated with lymphatic filariasis transmission were Normalised Difference Vegetation Index (NDVI), land cover, distance to waterbody, rainfall/precipitation, elevation, slope, day land surface temperature, average annual temperature, house type and distance to stable light. ConclusionsThis review is one of the steps towards understanding the associations between environmental determinantsand transmission of lymphatic filariasis. These results can be used in future evidence-based strategies to strengthen surveillance and control strategies.
