Engineering a mobile health tool for resource-poor settings to assess and manage cardiovascular disease risk: SMARThealth study
Open accessAbstract
BACKGROUND: The incidence of chronic diseases in low- and middle-income countries is rapidly increasing both in urban and rural regions. A major challenge for health systems globally is to develop innovative solutions for the prevention and control of these diseases. This paper discusses the development and pilot testing of SMARTHealth, a mobile-based, point-of-care Clinical Decision Support (CDS) tool to assess and manage cardiovascular disease (CVD) risk in resource-constrained settings. Through pilot testing, the preliminary acceptability, utility, and efficiency of the CDS tool was obtained. METHODS: The CDS tool was part of an mHealth system comprising a mobile application that consisted of an evidence-based risk prediction and management algorithm, and a server-side electronic medical record system. Through an agile development process and user-centred design approach, key features of the mobile application that fitted the requirements of the end users and environment were obtained. A comprehensive analytics framework facilitated a data-driven approach to investigate four areas, namely, system efficiency, end-user variability, manual data entry errors, and usefulness of point-of-care management recommendations to the healthcare worker. A four-point Likert scale was used at the end of every risk assessment to gauge ease-of-use of the system. RESULTS: The system was field-tested with eleven village healthcare workers and three Primary Health Centre doctors, who screened a total of 292 adults aged 40 years and above. 34% of participants screened by health workers were identified by the CDS tool to be high CVD risk and referred to a doctor. In-depth analysis of user interactions found the CDS tool feasible for use and easily integrable into the workflow of healthcare workers. Following completion of the pilot, further technical enhancements were implemented to improve uptake of the mHealth platform. It will then be evaluated for effectiveness and cost-effectiveness in a cluster randomized controlled trial involving 54 southern Indian villages and over 16000 individuals at high CVD risk. CONCLUSIONS: An evidence-based CVD risk prediction and management tool was used to develop an mHealth platform in rural India for CVD screening and management with proper engagement of health care providers and local communities. With over a third of screened participants being high risk, there is a need to demonstrate the clinical impact of the mHealth platform so that it could contribute to improved CVD detection in high risk low resource settings.

TL;DR
The paper reports the agile, user-centred development and pilot testing of SMARThealth, a mobile clinical decision support tool for assessing and managing cardiovascular disease (CVD) risk in rural India. In the pilot, 11 village health workers and 3 primary health centre doctors screened 292 adults, with 34% identified as high CVD risk and 57% of ASHA-screened participants referred to a physician.
Key findings
- A total of 292 adults were screened: 227 by 11 ASHAs (mean age 51.4 ± 13.1 years) and 65 in-patients by 3 PHC physicians (mean age 55.3 ± 11.7 years); 34% of screened participants had a CVD risk score >30% or clinically high risk/CVD or both.
- Among 227 participants screened by ASHAs, the CDS tool identified 57% (n = 128) for physician referral, either for high CVD risk (n = 88) or impaired fasting glucose (n = 40).
- Median complete CVD risk assessment time was 00:21:10 (IQR 00:14:08); Step 3 (risk factor acquisition) took longest, median 00:10:33 (IQR 00:11:22), and completion time decreased as ASHAs performed more procedures.
- Usability: over 72% of screening procedures were rated easy to use, no user rated the application below 3 on a 4-point scale, and manual blood glucose entry errors occurred in 14/227 patients (median error 9.55 mg/dL, IQR 35.75 mg/dL); overall Bluetooth BP device usage rate was 55%.
Methods
- The CDS tool was developed using agile development and user-centred design, incorporating WHO/ISH 10-year CVD risk charts and guideline-based management recommendations, with a server-side OpenMRS electronic medical record and Android tablets.
- Field testing involved 11 ASHAs performing door-to-door screening of 227 community participants in 3 rural Andhra Pradesh villages, plus 3 PHC physicians screening 65 in-patients; detailed usage analytics focused on 3 ASHAs (npB1, npM1, npL1) who performed 28, 20, and 16 assessments.
- An analytics framework logged clicks and timestamps; bootstrapping estimated mean procedure times and 95% CIs; manually entered glucose values were compared with glucometer readings; a four-point Likert scale assessed usability after every risk assessment.
Limitations
- Stated: the main limitation was the limited sample size, and the pilot was not designed to be representative; infrastructural barriers included power supply limited to fixed times of day, requiring frequent tablet charging.
- Evident: the paper focuses on ASHA usage and does not report clinical outcomes or effectiveness; physician usage data are not analysed in detail; only 3 ASHAs were selected for detailed usage analysis; usability was assessed at the end of each procedure and may be subject to social desirability bias despite the authors’ efforts to minimise it.

npM1's Bluetooth usage fraction does not equal 50%
MinorTen uses in 28 procedures is 35.7%, not 50%. The paper also states that npM1 performed 20 assessments, for which 10 uses would equal 50%.

MinorThe text says risk-meter usage was much lower than usage of the other sections for all three ASHAs, but Table 4 gives npL1 the same 81% usage for all three sections.
“It can be observed that the usage of the risk projection meter was much lower in comparison to the other sections for the three ASHAs.”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-06.
Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-06.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
