The effect of disruption due to COVID-19 on operating room utilization: Experience from a secondary care hospital in Riyadh, Saudi Arabia.

The disruption caused due to corona virus disease-2019 (Covid-19) has affected the overall health care delivery worldwide. The elective services were foremost to face the restrictions and closure, subsequently they were resumed only after adoption on newer protocols. We aimed to estimate the effect of COVID-19 restrictions on operative room utilization. This is a retrospective descriptive study. The surgical volume indicators were calculated and a comparison was made between pre-COVID-19 (April-June 2019) and COVID-19 phase (April-June, 2020). Pre-operative covid assessment through the RT-PCR test among the cases waiting for elective surgeries. Overall surgical volume decreased by 53%, which included 87% decrease in elective procedures and 8% decrease in emergency procedures. The overall OR utilization reduced by 63%. Highest reduction in the surgical volume was noted in bariatric surgery (no surgeries conducted in the COVID-19 phase), ophthalmology (99% reduction), and Ear, Nose and Throat surgery (ENT) surgery (92% reduction). Six patients tested positive for pre-operative RT-PCR from the sample of 261 cases posted for elective surgery during resumption phase of elective services, thereby giving the positivity rate of about 2.2%. We found a high level of reduction in the operating room utilization in a secondary care public sector hospital. The pre-operative assessment has enabled to find out the COVID-19 cases and hence preventing the unwanted spread of infection during the surgical procedures.
