Nationwide Implementation of a Digital Health Module for Chronic Kidney Disease Screening: A RE-AIM Evaluation in...

Background: Chronic kidney disease (CKD) is a major public health problem, primarily affecting patients with diabetes mellitus and/or hypertension. Early detection is critical to delay progression to renal replacement therapy. Therefore, this study aims to evaluate the implementation of a digital module for CKD detection in at-risk patients within the Peruvian Social Health Insurance system (EsSalud) during 2024. Materials and Methods: Data were collected through the Renal Health Module (MOSARE), a digital tool integrated into EsSalud's electronic health record for monitoring patients at risk of CKD. Key indicators were assessed using the RE-AIM framework: reach, effectiveness, adoption, implementation, and maintenance. Quantitative analyses evaluated patient identification, screening, and diagnosis, while qualitative analyses of technical documents identified barriers, facilitators, and stakeholder perceptions. Results: In 2024, MOSARE was implemented in a population of 1,667,856 insured individuals with CKD-related risk conditions, predominantly women (55.7%) and adults aged >55 years (88.3%). Nationwide, 93,266 patients were screened (5.59% reach), with 34.3% diagnosed with CKD. Screening coverage showed substantial geographic variability (0.35-29.59%). A total of 32,004 CKD cases were identified, with 84.2% in early stages (1-3A). Adoption reached 66.8% of level I and II healthcare facilities, with variability across networks. Regarding maintenance, 65% of trained facilities sustained active use. Implementation gaps were associated with interoperability issues, resource limitations, and training variability. Conclusions: MOSARE proved to be a feasible and operationally sensitive tool for CKD screening and risk identification, improving integration of renal care. However, addressing technical, training, and resource barriers is essential to ensure sustainability and scalability.
