Impact of case-relevant and case-irrelevant communication within the surgical team on surgical-site infection.

Surgical‐site infections (SSIs) are the most common complications after surgery. An influence from talking and distractions during surgery on patient outcomes has been suggested, but there is limited evidence. The aim of this prospective observational study was to assess the relationship between intraoperative communication within the surgical team and SSI, and between intraoperative distractions and SSI.

Assessing distractors and teamwork during surgery: developing an event-based method for direct observation

Objective To develop a behavioural observation method to simultaneously assess distractors and communication/teamwork during surgical procedures through direct, on-site observations; to establish the reliability of the method for long (>3 h) procedures. Methods Observational categories for an event-based coding system were developed based on expert interviews, observations and a literature review. Using Cohens κ and the intraclass correlation coefficient, interobserver agreement was assessed for 29 procedures. Agreement was calculated for the entire surgery, and for the 1st hour. In addition, interobserver agreement was assessed between two tired observers and between a tired and a non-tired observer after 3 h of surgery. Results The observational system has five codes for distractors (door openings, noise distractors, technical distractors, side conversations and interruptions), eight codes for communication/teamwork (case-relevant communication, teaching, leadership, problem solving, case-irrelevant communication, laughter, tension and communication with external visitors) and five contextual codes (incision, last stitch, personnel changes in the sterile team, location changes around the table and incidents). Based on 5-min intervals, Cohens κ was good to excellent for distractors (0.74–0.98) and for communication/teamwork (0.70–1). Based on frequency counts, intraclass correlation coefficient was excellent for distractors (0.86–0.99) and good to excellent for communication/teamwork (0.45–0.99). After 3 h of surgery, Cohens κ was 0.78–0.93 for distractors, and 0.79–1 for communication/teamwork. Discussion The observational method developed allows a single observer to simultaneously assess distractors and communication/teamwork. Even for long procedures, high interobserver agreement can be achieved. Data collected with this method allow for investigating separate or combined effects of distractions and communication/teamwork on surgical performance and patient outcomes.

Noise peaks influence communication in the operating room. An observational study

Abstract Noise peaks are powerful distractors. This study focuses on the impact of noise peaks on surgical teams’ communication during 109 long abdominal surgeries. We related measured noise peaks during 5-min intervals to the amount of observed communication during the same interval. Results show that noise peaks are associated with less case-relevant communication; this effect is moderated by the level of surgical experience; case-relevant communications decrease under high noise peak conditions among junior, but not among senior surgeons. However, case-irrelevant communication did not decrease under high noise level conditions, rather there was a trend to more case-irrelevant communication under high noise peaks. The results support the hypothesis that noise peaks impair communication because they draw on attentional resources rather than impairing understanding of communication. As case-relevant communication is important for surgical performance, exposure to high noise peaks in the OR should be minimised especially for less experienced surgeons. Practitioner Summary: This study investigated whether noise during surgeries influenced the communication within surgical teams. During abdominal surgeries, noise levels were measured and communication was observed. Results showed that high noise peaks reduced the frequency of patient-related communication, but did not reduce patient-irrelevant communication. Noise may negatively affect team coordination in surgeries.

Noise in the Operating Room Distracts Members of the Surgical Team. An Observational Study

BackgroundNoise pollution in operation rooms may distract the surgical team members. In particular during phases of high task complexity, noise can jeopardize concentration. Phases of high complexity are related to task specificities and may thus be different for different members of the surgical team.Study designNoise exposure was measured during 110 open abdominal surgeries. Distinguishing three phases (opening, main phase, and closing), noise was related to self-report of distraction levels by main and secondary surgeons, scrub nurses and anesthetists.ResultsNoise pollution was higher than recommended levels for concentrated work. Adjusted for duration, surgical type, and difficulty of the surgery, results showed that second surgeons are more likely distracted when noise pollution was high in the main phase; and anesthetists are more likely distracted when noise pollution was high during the closing phase. Main surgeons’ and scrub nurses’ concentration was not impaired by measured noise levels.ConclusionsIn phases with higher concentration demands, noise pollution was particularly distracting for second surgeons and anesthetist, corresponding to their specific task demands (anesthetists) and experience (second surgeons). Reducing noise levels particularly in the main and closing phase of the surgery may reduce concentration impairments.

Assessing Perceptions of Teamwork Quality Among Perioperative Team Members

Successful surgery depends on collaboration and mutual trust among interdisciplinary team members. We compared teamwork quality as perceived by surgeons, anesthesia care providers, and perioperative nurses using two surveys in the same hospital. The general survey sent to the homes of the OR personnel revealed teamwork climate scores in the medium to high range. Attending surgeons were significantly more satisfied than perioperative nurses and resident surgeons; anesthesiologists were significantly more satisfied than perioperative nurses. A second single-item survey administered immediately after elective open abdominal surgical procedures also showed relatively high satisfaction with teamwork. Results of the second survey, however, showed that attending surgeons were significantly less satisfied than the members of all the other professions, and perioperative nurses were significantly more satisfied than the members of all the other professions. We conclude that general surveys about teamwork quality among members of surgical teams may not necessarily reflect teamwork quality during actual surgical procedures.
