A theory-based instrument to evaluate team communication in the operating room: balancing measurement authenticity and reliability.

BACKGROUND: Breakdown in communication among members of the healthcare team threatens the effective delivery of health services, and raises the risk of errors and adverse events. AIM: To describe the process of developing an authentic, theory-based evaluation instrument that measures communication among members of the operating room team by documenting communication failures. METHODS: 25 procedures were viewed by 3 observers observing in pairs, and records of events on each communication failure observed were independently completed by each observer. Each record included the type and outcome of the failure (both selected from a checklist of options), as well as the time of occurrence and a description of the event. For each observer, records of events were compiled to create a profile for the procedure. RESULTS: At the level of identifying events in the procedure, mean inter-rater agreement was low (mean agreement across pairs 47.3%). However, inter-rater reliability regarding the total number of communication failures per procedure was reasonable (mean ICC across pairs 0.72). When observers recorded the same event, a strong concordance about the type of communication failure represented by the event was found. DISCUSSION: Reasonable inter-rater reliability was shown by the instrument in assessing the relative rate of communication failures displayed per procedure. The difficulties in identifying and interpreting individual communication events reflect the delicate balance between increased subtlety and increased error. Complex team communication does not readily reduce to mere observation of events; some level of interpretation is required to meaningfully account for communicative exchanges. Although such observer interpretation improves the subtlety and validity of the instrument, it necessarily introduces error, reducing reliability. Although we continue to work towards increasing the instrument's sensitivity at the level of individual categories, this study suggests that the instrument could be used to measure the effect of team communication intervention on overall failure rates at the level of procedure.

Epidemiologic observations of operating room infections resulting from variations in ventilation and temperature.

Over a period of years the ventilation system of a community hospital progressively deteriorated until it no longer met regulatory guidelines. The hospital, a publicly funded military facility, requested funding to repair the ventilation system, but funds were not forthcoming because of budget austerity. When an increase in infections was documented, high-risk operations were curtailed and funding was expedited. With the new improved ventilation system the operating rooms once again met regulatory guidelines and infections returned to baseline rates. Throughout the period infections remained below recognized national levels.

The lack of benefit of tracheal extubation in the operating room after coronary artery bypass surgery.

Although early tracheal extubation in cardiac anesthesia is safe and cost beneficial, questions still remain regarding how early after cardiac surgery patients should be tracheally extubated (TE). Our objective was to determine the effects on resource use if patients scheduled for coronary artery bypass grafting have TE in the operating room (OR). We studied 100 consecutive patients undergoing elective coronary artery bypass grafting, requiring extracorporeal circulation, and those eligible for a fast-track pathway. At the end of the procedure, the patients were evaluated for TE in the OR if they were hemodynamically stable, were without significant bleeding, and fulfilled clinical and blood gas analysis variables. Patients who did not meet the requirements had TE in the intensive care unit (ICU). Fifty patients had TE in the OR and 50 patients in the ICU. Time in the OR after skin closure, ICU length of stay, and postoperative length of stay were similar between the groups. Four patients (8%) in the OR group were tracheally reintubated secondary to respiratory depression (P = 0.11). Three patients (6%) in the OR group had postoperative myocardial infarction, and one postoperative myocardial infarction (2%) occurred in the ICU group (P = 0.61). All four patients recovered satisfactorily. The incidences of other complications were similar between groups.

Is unplanned return to the operating room a useful quality indicator in general surgery?

HYPOTHESIS: To test our hypothesis that unplanned return to the operating room (OR) is a useful quality indicator, we examined how often and for what reasons patients go back to the OR in a broad-based general surgery practice. DESIGN AND SETTING: Prospective cohort study at a rural tertiary care center. PATIENTS: Consecutive series of 3044 patients undergoing general surgery procedures in the OR between September 1, 1998, and March 31, 2000. Information about all postoperative adverse events occurring before discharge or within 30 days (whichever was longer) was collected prospectively. Unplanned return to the OR was defined as any secondary procedure required for a complication resulting directly or indirectly from the index operation. MAIN OUTCOME MEASURES: Unplanned return to the OR, mortality, and hospital charges. RESULTS: Overall, 107 (3.5%) had an unplanned return to the OR. A relatively small number of inpatient procedures accounted for a disproportionate share of unplanned reoperations, including colon resection (18% of total reoperations), renal transplant (9%), gastric bypass (6%), and pancreatic resection (6%). As expected, hospital charges were markedly higher for patients with unplanned returns to the OR. Reoperation was also associated with higher mortality rates; statistically significant increases were noted for pancreatic resection (33% vs 3.7%; P =.04), esophagogastrectomy (100% vs 4.2%; P =.002), and laparoscopic Nissen fundoplication (50% vs 0%; P =.01). Overall, 91 reoperations (85%) were for complications occurring at the original surgical site, including those related to an anastomosis (n = 16), surgical wound (n = 21), infection (n = 16), bleeding (n = 12), and other (n = 26). CONCLUSIONS: Unplanned returns to the OR occur across a broad spectrum of general surgical procedures and carry significant implications. Because they most often reflect problems related to the procedure itself, reoperation rates may be useful for monitoring quality across hospitals and for identifying opportunities for quality improvement locally.

Cross-industry benchmarking: is it applicable to the operating room?

The use of benchmarking has been growing in nonmedical industries. This concept is being increasingly applied to medicine as the industry strives to improve quality and improve financial performance. Benchmarks can be either internal (set by the institution) or external (use other's performance as a goal). In some industries, benchmarking has crossed industry lines to identify breakthroughs in thinking. In this article, we examine whether the airline industry can be used as a source of external process benchmarking for the operating room.

[Pollution of operating room air by anesthetic gases in relation to the air conditioning method and anesthesia techniques].

Volatile anesthetics are suspected to cause various health risks even in subnarcotic concentrations (hepatotoxicity, mutagenicity, teratogenicity). Yet only for halothane a limit (MAK-value = 5 ppm) has been established for the entire FRG. In addition, in 1991 Hamburg and Schleswig-Holstein defined preliminary limits for isoflurane, enflurane and nitrous oxide. We analysed the pollution of operating-room air by narcotic gases in 20 hospitals of Niedersachsen. In several cases limits have been exceeded evidently. Reasons for high concentrations were: insufficient room ventilation, defective air-conditioning plants, technical defects (leakage) and high gas emission due to special techniques in anesthesia (bronchoscopy). In order to take care of personnel-health air concentration of anesthetic gases should be kept as low as possible by the help of sufficient room ventilation avoiding unnecessary emissions.
