Key result
Implementation of an electronic medical record system significantly increased the proportion of delayed operating theatre sessions from 13.1% at baseline to 88.2% in the first month of use (p<0.0001).
Why the study?
No study had evaluated the impact of electronic medical record system implementation on operating theatre efficiency in Australia.
Does the implementation of an electronic medical record system reduce operating theatre efficiency in general surgery sessions?

Does the implementation of an electronic medical record system reduce operating theatre efficiency in general surgery sessions?
Absolute Event Rate: 88.2% vs 13.1%
p-value: p=<0.0001
Implementation of an EMR system initially decreases operating theatre efficiency with increased start time delays, but efficiency begins to recover by the second month.
May increase theatre delays after EMR rollout; leaves open optimal implementation strategies for surgical services.
Background: The utilization of electronic medical record (EMR) system has become the mainstay of healthcare system in developed countries. In the last five years, Queensland Health has gradually implemented EMR system for hospitals in Queensland, Australia. As far as we are aware, no study has been conducted to assess the impact of the EMR implementation on operating theatre efficiency in Australia.Methods: A retrospective review of general surgery operating room on time start data was performed for a period of 2 months prior and 2 months following implementation of the EHR. A delay was defined as the time between the scheduled start time and “first in” times. Outcomes measured included the total number of sessions run, number of sessions starting late, average delay time and case cancellations.Results: During the EMR training period, the number of sessions which had delayed increased from 13.2％ to 31.0%. Following implementation of the EMR, delays were present for 88% of sessions for the first month with an average delay time of 21.8 minutes. The second month showed an overall improvement with 69% of sessions delayed and a reduced average delay time of 10.4mins.Conclusions: The implementation of a new electronic medical record system is associated with delays in theatre start times especially during the training period and first month of use. Evidence of recovery of service efficiency however is seen by the second month post-implementation with further expected improvement if trends continue.

Chuang et al. (2019) conducted an observational in General surgery operating room sessions (n=100). Electronic medical record (EMR) system implementation vs. Pre-implementation (baseline) was evaluated on Proportion of sessions delayed (first case start time ≥1 min over scheduled time) (p=<0.0001). Implementation of an electronic medical record system significantly increased the proportion of delayed operating theatre sessions from 13.1% at baseline to 88.2% in the first month of use (p<0.0001).
