Cost and cost-effectiveness of mHealth interventions for the prevention and control of type 2 diabetes mellitus: A systematic review
Introduction
In 2017, diabetes was ranked as the fourth leading cause of disability globally [1]. The health consequences of diabetes cause a marked loss of productivity and economic burden to patients, healthcare providers and country’s economies, mounting to 1.8% of the global gross domestic product (GDP) and 12% of the global health expenditure in 2018 [2], [3]. Over 80% of yearly deaths due to diabetes occur in developing countries causing drastic economic consequences compared to their developed counterparts [4]. Diabetes is notoriously difficult to control with only about 50% of patients reaching their treatment targets [5]. There are multifactorial explanations for this, including the challenges T2DM poses on patients’ habits surrounding diet and exercise. Many patients demonstrate low willingness to change their perceptions and actions to alter their undesirable lifestyle habits [6], [7]. Moreover, treatment plans often consist of multiple daily pharmacological interventions which contribute to poor medication adherence [8].
Mobile health (mHealth) uses technology to encourage patients’ lifestyle modification and medication adherence by providing portable, every-day interventions to empower patients and encourage them to adhere to their management plans [9]. The rise of mHealth has heavily correlated with the exponential growth in internet access which has allowed for the creation of wireless healthcare opportunities combining patient empowerment with the convenience of mobile devices [10], [11]. MHealth interventions are becoming prominent amongst several medical specialties encompassing preventative, curative and chronic management goals. Additionally, mHealth reduces geographic related disparities in health care by removing physical barriers to accessing medical information and providing individuals a “virtual” platform. Successful MHealth interventions have shown to significantly reduce hospital inpatient admissions and prompt a 63% reduction in number of admission days [12].
MHealth interventions targeting diabetes have shown clinical effectiveness in both the prevention and management of T2DM [13], [14], [15]. Management based interventions have proven to be particularly successful at reducing haemoglobin A1c (HbA1c) levels amongst people with T2DM [14]. A meta-analysis investigating mobile phone interventions for glycaemic control demonstrated that among 22 trials there was a statistically significant improvement in glycaemic control amongst users of the online intervention [16]. Similarly, another review found that glycaemic control results were significant amongst T2DM when mobile text messaging interventions were combined with an internet based intervention [17]. MHealth interventions have proven to be low cost and cost-effective across various medical specialties [18], [19]. Economic evidence is crucial to guide policy makers and funders towards implementing mHealth interventions. Nevertheless, there is a large gap in the literature analysing the costs and cost-effectiveness of mHealth interventions addressing T2DM [20]. To the best of our knowledge, there is currently no published literature summarising the cost or cost-effectiveness of mHealth interventions targeting the prevention and control of T2DM. This study aims to systematically review, analyse and summarise the published evidence on the cost and cost-effectiveness of mHealth interventions for T2DM, as well as, to assess the quality of the published evidence.

Methods
Our systematic review was reported in accordance with the 2015 PRISMA statement [21]. Our protocol was registered with the International Prospective Register of Systematic Reviews in January 2019 (PROSPERO registration number CRD42019123476) and it is published elsewhere [22].
Results
Our systematic database search identified the following number of studies from the three databases:
- •
Pubmed: 2309 items found on 4th May 2019
- •
EMBASE: 1744 items found on 6th May 2019
- •
Web of Science: 1223 items found on 5th May 2019
The study selection is shown in Fig. 1 using the preferred reporting items for a systematic review and meta-analysis protocol (PRISMA-P) flowchart [21]. At the end of the selection process we had 23 final studies to include in our systematic review.
Discussion
The current study aims to systematically review and summarise the research surrounding the costs and cost-effectiveness of mHealth interventions targeting T2DM. Our results have shown that, overall, the quality of reporting was weak among both partial and full economic evaluations, however, poorer amongst partial evaluations. The cost varied based on the type of intervention, the number of technologies integrated and whether it was combined with a non-mHealth component. Importantly, all those
Conclusion
This review is the first to evaluate and summarise this area of the literature. Findings point to growing economic evidence on mHealth intervention targeting T2DM, although a limited number of full economic evaluation or cost-effectiveness studies exist. The cost of mHealth interventions varied substantially based on type and combination of technology used. However, where cost-effectiveness results reported, the intervention was highly cost-effective. Continued efforts towards integration of
Author contributions
HHB conceptualized the study. GR carried out the literature review of which the strategy was reviewed by AH and HHB. GR and AH assessed the quality of included studies independently. HHB was involved if there were any discrepancies in the assessment of the study quality. GR wrote the first draft of the manuscript which was individually reviewed by both AH and HHB. All authors have approved the final version of the manuscript.
