Optimizing Utilization of Cardiothoracic Surgical Facilities in Sri Lanka: A Cost-Benefit Analysis of Extending Operating Hours to Reduce Waiting Lists

This study investigates the underutilization of cardiothoracic theatres and cardiac catheterization labs in three major Sri Lankan hospitals: National Hospital Galle, Sri Jayewardenepura General Hospital, and National Hospital Jaffna. Using a descriptive analytical design, data on operational hours, surgery types, and staffing were collected to estimate potential efficiency gains from utilizing non-operational hours. Findings revealed over ¹6,864 non-utilized hours annually, which could enable ³,³7³ additional surgeries. These procedures would yield approximately 7,99³.54 Quality-Adjusted Life Years (QALYs), translating to an economic benefit of nearly $79.9³ million. The study concludes that extending operational hours and involving healthcare professionals from other institutions could address surgical backlogs without the need for costly infrastructure expansion. Policy recommendations include extending theatre hours, contractual staff engagement, and incentivizing off-hour work. The findings highlight a cost-effective strategy to optimize healthcare delivery and improve access to life-saving procedures, ultimately enhancing patient outcomes and health system efficiency in Sri Lanka.
