Role of tele-ICU in transforming critical care delivery in India

The ongoing challenge of delivering high-quality critical care in resource-limited settings has been magnified by the global shortage of trained intensivists and critical care nurses. In India, the estimated availability of intensive care unit (ICU) beds is around 2.3 per 100 000 population, reflecting a major shortfall compared to global standards, disproportionately concentrated in tier-1 and tier-2 cities.¹ As such, a large proportion of the population remains underserved in terms of access to specialized critical care. Despite the advanced healthcare infrastructure in developed countries, delivering high-quality care to remote and rural populations remain a persistent challenge. Tele-ICUs have emerged as an innovative solution, enabling continuous remote monitoring, real-time expert consultation, and decision support for critically ill patients, thereby bridging the gap in access to specialized care.^2,3

Globally, tele-ICUs have shown major benefits, including improved patient outcomes, optimized resource utilization, and standardized evidence-based care practices. Studies from the USA, for instance, have shown that tele-ICU implementation is associated with reduced ICU mortality, shorter ICU lengths of stay, and improved adherence to protocols for ventilator-associated pneumonia, stress ulcer prophylaxis, and venous thromboembolism prevention.⁴ The continuous monitoring capability provided by tele-ICUs facilitates timely interventions, enhances patient safety, and allows for more efficient coordination of transfers between healthcare facilities.⁵

In India, telemedicine’s regulatory framework was formalized in 2020 through the telemedicine practice guidelines issued by the Ministry of Health and Family Welfare. These guidelines address key aspects of telemedicine practice, including clinician training, patient consent, data privacy, and ethical considerations, thereby laying the foundation for structured expansion of tele-ICU services. A pioneering initiative in this domain is the government-supported tele-ICU program established at Sanjay Gandhi Postgraduate Institute of Medical Sciences (SGPGIMS), Lucknow. The project, funded through corporate social responsibility contributions from the PowerGrid Corporation of India and technical support from cloud physicians, Bengaluru and CoreByte Systems Private Limited (CSPL), India, implemented a hub-and-spoke model connecting SGPGIMS, the central hub, with state medical college ICUs as spokes. This setup ensures 24/7 monitoring and guidance from trained intensivists and registered nurses at the hub, while bedside teams at the spokes deliver direct patient care. The program has shown remarkable success in extending critical care expertise to regions lacking trained intensivists, standardizing care protocols, and improving overall patient outcomes.

Operationally, the SGPGIMS tele-ICU integrates real-time audiovisual connectivity, electronic medical records, and picture archiving systems to facilitate comprehensive monitoring. The remote teams participate in daily rounds, on-demand consultations, and inter-hospital transfer coordination. This model not only improves adherence to evidence-based practices but also enhances team collaboration and safety perceptions among bedside staff.⁶ Nurses and other healthcare providers at spoke ICUs report improved confidence in clinical decision-making, better teamwork, and heightened patient safety awareness.⁵

The decision-making authority of remote tele-ICU teams has been correlated with improved outcomes, highlighting the importance of integrating these teams into the care process rather than limiting their role to advisory functions.⁷ However, in India, tele-ICU services are a relatively recent development, and robust public-sector evidence on their impact on ICU mortality and length of stay is still evolving. Nonetheless, studies from private tele-ICU models have shown potential clinical benefits, including improved in-hospital cardiac arrest outcomes and earlier detection of life-threatening haemodynamic deterioration.^8,9

Despite these advantages, several barriers to effective tele-ICU implementation persist, including high infrastructure costs, resistance to workflow changes, and gaps in staff training.¹⁰ Addressing these challenges is essential for sustainable expansion. Evidence suggests that engagement of bedside staff in program planning, structured training, and clear communications is critical to improving acceptance and collaboration between hub and spoke teams.

The SGPGIMS tele-ICU initiative became operational on ¹ February 2024 and functions as a hub-and-spoke critical care network to support peripheral ICUs. Each 10-bedded spoke ICU is staffed by 1 consultant, 1 senior resident, 2 junior residents, 4–6 nurses per shift, and a dedicated data entry operator responsible for real-time data integration into the tele-ICU platform. Structured tele-rounds are conducted twice daily, with each ICU having 2–3 teleconsultations per day, supplemented by an additional 2–3 unscheduled tele-ICU consultations daily. The tele-ICU model has improved the timeliness of clinical interventions through structured tele-rounds and real-time case discussions. Prospective data collection is ongoing to evaluate the impact of tele-ICU consultations on ICU mortality and other key outcomes, including length of stay, early clinical improvement, reintubation rates, early discharges, and adherence to evidence-based ICU care bundles, catheter-associated urinary tract infection (CAUTI), ventilator-associated pneumonia (VAP), and central line-associated bloodstream infection (CLABSI). A formal cost-effectiveness analysis assessing resource utilization and avoidance of unnecessary investigations, drugs, and treatments is underway, with preliminary audits indicating improved protocol adherence, more rational antibiotic use, and a reduction in ICU length of stay with a favourable impact on mortality.

The SGPGIMS tele-ICU initiative demonstrates that a government-supported, CSR-funded tele-ICU model is not only feasible but also impactful. The initial 100-bed network has received national recognition, including the Federation of Indian Chambers of Commerce and Industry (FICCI) Award 2025 for safety initiatives in public hospitals. Encouraged by this success, expansion plans are underway to connect an additional 600 beds across 36 medical colleges and 18 district hospitals, promising broader access to standardized critical care services in Uttar Pradesh and offering a scalable model for other Indian states.

Despite the availability of high-quality internet bandwidth, intermittent connectivity disruptions were encountered during the initial phase. Variability in clinical expertise across spoke ICUs necessitated repeated and structured training sessions to ensure uniform understanding and adherence to tele-ICU protocols. Early in the program, some resistance to remote supervision was observed among bedside teams, which was gradually addressed through sustained engagement, regular interactions, and trust-building measures. Additionally, the initial costs associated with hardware procurement, software deployment, and dedicated manpower posed logistical and financial constraints during the rollout phase.

Tele-ICU represents a viable and scalable solution to the shortage of critical care expertise in India by enabling timely specialist support, improving adherence to evidence-based care practices, and reducing disparities between urban and peripheral healthcare facilities.
