Optimizing Operating Room Capacity Across U.S. Hospitals

A Call to Improve Surgical Efficiency and Access Through Operational Excellence and Collaborative Networks

Authored and reviewed by the DIN team, June 2025

Executive Summary

Operating rooms (ORs) represent high‑cost, high‑revenue assets vital to hospital operations. Yet, significant OR capacity remains unused across the country, resulting in financial inefficiencies and constrained patient access. This paper examines OR underutilization in both urban and rural hospitals, identifies primary drivers, and proposes targeted solutions to optimize utilization.

Introduction

Effective utilization of ORs is essential for maximizing institutional revenue, minimizing surgical wait times, and streamlining overall hospital efficiency. However, a substantial portion of scheduled OR time goes unused. Drawing on peer‑reviewed studies, this analysis quantifies underutilization in urban and rural settings and explores underpinning factors.

Methodology

A structured literature review was conducted of peer‑reviewed articles published between 2016 and 2024. Searches in PubMed Central and BMC Patient Safety in Surgery employed keywords including “operating room utilization,” “first‑case delays,” “rural hospitals,” and “urban hospitals.” Selected studies provide quantitative measures of idle OR time, delay incidence, and systemic barriers.

Urban Hospital Underutilization

Despite high surgical volumes, urban hospitals regularly experience idle OR hours. In a 2024 multicenter analysis of large metropolitan hospitals, nearly 65% of first‑case procedures began later than scheduled, contributing to an average OR utilization rate of only 68% during core hours (Coxbauer et al., 2024). Key contributors include variability in case lengths, late patient arrivals, and protracted turnover processes (Jones et al., 2022).

Rural Hospital Underutilization

Rural facilities contend with lower case volumes and intermittent OR closures. A 2016 system‑design study found that in rural ORs, unused capacity are driven by limited surgical diversity and staffing shortages (Cochran et al., 2016). Additionally, rural hospitals frequently transfer routine surgical cases to urban centers, further diminishing local OR use and exacerbating access disparities (Imsirovic et al., 2023).

Discussion

Urban underutilization is largely operational, stemming from scheduling inefficiencies and procedural delays. Conversely, rural underutilization reflects structural constraints such as low volume and workforce limitations. Both contexts incur substantial revenue loss—estimated in the millions annually per facility—and prolong patient waitlists, potentially impacting clinical outcomes.

Recommendations

1. Real‑Time Scheduling Algorithms: Deploy predictive analytics to forecast case durations and dynamically adjust OR block times.

2. Enhanced First‑Case Protocols: Standardize preoperative checklists and enforce strict patient arrival windows to minimize start delays.

3. Flexible Block Release: Institute early block‑release policies to reallocate unused OR slots to other services or surgeons.

4. Regional OR Networks: Form consortia enabling rural hospitals to share staffing and manage overflow cases, sustaining local OR operations.

5. Tele‑Perioperative Support: Expand telehealth consultations for rural surgical teams to bolster case volume and reduce transfers.

Conclusion
Underutilization of OR capacity remains a pervasive challenge in both urban and rural U.S. hospitals. By adopting data‑driven scheduling, standardized operational protocols, and collaborative network models, institutions can enhance financial performance and broaden patient access to surgical care.
