Healthcare delivery in urban India is at a turning point. The simultaneous rise of lifestyle-linked chronic illnesses and the accelerating penetration of sensor-embedded wearable technologies have opened new clinical possibilities for continuous, patient-centred disease monitoring outside conventional hospital environments. This paper investigates the operational efficacy, deployment barriers, and multi-stakeholder adoption dynamics of wearable health devices across ten purposively selected tertiary-care and multispecialty hospitals in Jaipur, Rajasthan. Drawing on a structured synthesis of ninety peer-reviewed publications alongside a proposed cross-sectional mixed-method field study involving 391 respondents — comprising chronic disease patients, treating clinicians, and hospital information-technology personnel — the study constructs and validates a conceptual framework that positions four independent variable classes (device usage patterns; operational-technical infrastructure; patient socio-behavioural factors; and institutional readiness) as joint determinants of three outcome domains: clinical improvement, patient engagement, and operational efficiency. Preliminary findings from the literature synthesis reveal that wearable devices demonstrate consistent clinical utility in diabetes, hypertension, cardiovascular disease, and chronic obstructive pulmonary disease management, yet their translation into sustained operational practice within Indian urban hospitals is constrained by fragmented EHR interoperability, heterogeneous patient digital literacy, inadequate staff training, and immature data governance architecture. An original five-component Wearable Device Operational Integration Model (WDOIM) is proposed to guide hospital administrators and health-technology policymakers in designing context-sensitive, scalable deployment programmes. The paper fills an identified tri-level research gap — theoretical, contextual, and methodological — and advances a research agenda grounded in the specific institutional, demographic, and infrastructural realities of Rajasthan’s evolving digital health ecosystem.
