PurposeThe research was conducted to evaluate the noise levels and the effect of noise on the workload and stress levels of the operating room (OR) staff of a public hospital.DesignDescriptive and cross-sectional study.MethodsThe data were obtained by measuring ambient noise during 403 orthopaedic, urological, and general surgeries on weekdays between July and October 2019. We measured the noise by dividing the surgery into three phases. These phases are as follows: from the entry of the patient, induction of anesthesia, and preparation of the surgical area until the start of the procedure (Phase I), from the incision until the completion of closure and dressing application (Phase II), from the completion of closure and dressing application until the exit of the patient (Phase III). Furthermore, the workload and stress levels of 45 OR staff who work in the general surgery, orthopaedics, and urology ORs were measured. Data were collected using a CA 834 noise measurement device, State-Trait Anxiety Inventory (STAI Form TX-I), the National Aeronautics and Space Administration (NASA) Task Load Index Workload Scale, and Information form related to surgery and ORs.FindingsThe noise in the OR was higher than 35 dB, A-weighted [dB(A)], the limit proposed by the World Health Organization for hospitals. Phase I average noise level was 63.00 ± 3.50, Phase II average noise level was 62.94 ± 3.75, and Phase III average noise level was 63.67 ± 2.81. The mean anxiety score was 34.50 ± 6.09. The total workload level was found to be 56.91 ± 15.67. Anxiety scores and workload scores had positive weak and moderate correlations with noise levels (P < .01).ConclusionsThe noise in the OR was high, and anxiety scores and workload scores correlated positively with noise levels.Copyright © 2020 American Society of PeriAnesthesia Nurses.
