Current Status and Future Directions of mHealth Interventions for Health System Strengthening in India: Systematic Review

Abstract

BackgroundWith the exponential increase in mobile phone users in India, a large number of public health initiatives are leveraging information technology and mobile devices for health care delivery. Given the considerable financial and human resources being invested in these initiatives, it is important to ascertain their role in strengthening health care systems.ObjectiveWe undertook this review to identify the published mobile health (mHealth) or telemedicine initiatives in India in terms of their current role in health systems strengthening. The review classifies these initiatives based on the disease areas, geographical distribution, and target users and assesses the quality of the available literature.MethodsA search of the literature was done to identify mHealth or telemedicine articles published between January 1997 and June 2017 from India. The electronic bibliographic databases and registries searched included MEDLINE, EMBASE, Joanna Briggs Institute Database, and Clinical Trial Registry of India. The World Health Organization health system building block framework was used to categorize the published initiatives as per their role in the health system. Quality assessment of the selected articles was done using the Cochrane risk of bias assessment and National Institutes of Health, US tools.ResultsThe combined search strategies yielded 2150 citations out of which 318 articles were included (primary research articles=125; reviews and system architectural, case studies, and opinion articles=193). A sharp increase was seen after 2012, driven primarily by noncommunicable disease–focused articles. Majority of the primary studies had their sites in the south Indian states, with no published articles from Jammu and Kashmir and north-eastern parts of India. Service delivery was the primary focus of 57.6% (72/125) of the selected articles. A majority of these articles had their focus on 1 (36.0%, 45/125) or 2 (45.6%, 57/125) domains of health system, most frequently service delivery and health workforce. Initiatives commonly used client education as a tool for improving the health system. More than 91.2% (114/125) of the studies, which lacked a sample size justification, had used convenience sampling. Methodological rigor of the selected trials (n=11) was assessed to be poor as majority of the studies had a high risk for bias in at least 2 categories.ConclusionsIn conclusion, mHealth initiatives are being increasingly tested to improve health care delivery in India. Our review highlights the poor quality of the current evidence base and an urgent need for focused research aimed at generating high-quality evidence on the efficacy, user acceptability, and cost-effectiveness of mHealth interventions aimed toward health systems strengthening. A pragmatic approach would be to include an implementation research component into the existing and proposed digital health initiatives to support the generation of evidence for health systems strengthening on strategically important outcomes.

Perceptions of factors influencing the introduction and adoption of electronic immunization registries in Tanzania and Zambia: a mixed methods study

“…Digital health interventions (DHIs) have become more prolific across health programs in low-and middleincome countries (LMICs) in recent years [1][2][3][4]. As technology has become cheaper and more accessible, health programs are adopting DHI to improve the provision of and demand for health services.…”

Harnessing mHealth to improve the diabetes screening and diagnosis rate in rural Indian settings: a learning from health systems initiative

“…mHealth initiatives have been on rise in India with diabetes being the most researched in Indian context. 10 As per, ""mHealth and ICT Framework"" developed by World Health Organization (WHO), Johns Hopkins University Global mHealth Initiative, the United Nations Children"s Fund (UNICEF), and Frog Designs, to describe mHealth innovations health systems. 7 Our initiative falls under two mHealth ICT framework, Electronic decision support and Data collection and reporting.…”

Development of an mHealth Behavior Change Communication Strategy

“…India sees promise in mHealth innovations to improve rural healthcare due to the broad geographical coverage of communications infrastructure and the low cost and availability of mobile handsets [3,8,17]. According to a report from Telecom Regulatory authority of India, of the 1203.77 million number of telephone subscribers in January 2019, 45% (530.86 million) were rural telephone subscribers [31], opening the landscape to develop mHealth interventions that could reduce health disparities, improve healthcare outcomes, while leaving no one behind and achieving universal health coverage.…”
