Anesthesia screen use may impact operating room communication practices in otolaryngology

Failures in communication are a leading contributor to medical error. There is increasing attention on cultivating robust communication practices in the Operating Room (OR) to mitigate against patient injury and optimize efficient patient care. Few studies have evaluated how surgical equipment may introduce barriers to team dynamics.

We conducted a pilot observational study to examine the relationship between anesthesia screen drapes (which are used inconsistently) and the frequency of verbal exchanges between surgical and anesthesia members. 25 procedures spanning various procedures in Otolaryngology were covertly observed, 12 of which employed a screen. Verbal exchanges were recorded across three stages of the surgery: pre-procedure (before the draping), procedure (drapes placed throughout) and post-procedure (after the removal of the draping). Speaker and content of the exchange was noted as well as various features about the procedure.

Decreases in rates of exchanges were most pronounced during the procedure stage, although they did not reach significance on T-testing (p = 0.0719). After controlling for attending, table orientation and number of professionals, regression analysis did reveal a statistically significant decrease in rates of verbal exchanges during the procedure in the presence of the anesthesia screen (7.17 (± 6.33) versus 2.23 (± 1.00), p = 0.0318). Differences were also significant among surgeon-initiated and patient-care-related exchanges (p = 0.0168 and p = 0.0432, respectively). Decreases in anesthesiologist-initiated and non-clinical exchanges did not reach significance (p = 0.1530 and p = 0.5120, respectively).

This pilot study suggests that anesthesia screens may negatively impact communication practices in the OR.
