OBJECTIVE: To describe our initial experience with a computerized telecommunication system, termed the interactive voice-response system, to record resident performance of laparoscopic surgery. METHODS: After completing a laparoscopic procedure, the surgeon and resident telephone a toll-free number independently and respond to three prerecorded statements using a Likert scale of 1 to 5. The caller then is asked to describe the resident's response to critical incidents or elements of surprise that arose during the surgery. The ratings and verbal comments are compiled, transcribed, and forwarded to the respective resident. The resident (and program director) can hear the verbal comments by entering a four-digit code. RESULTS: Between May 1, 1995, and May 31, 1996, 430 cases were reported by 11 surgeons and 16 residents using the interactive voice-response system. One hundred ninety-five (45%) procedures were entered by both the resident and surgeon. A survey undertaken during the introductory phase of the project revealed that five of the seven residents exposed to the system found that it provided useful feedback and preferred the system to traditional in-service reporting methods. In addition, five residents thought that the system complemented the personal feedback they received in the operating room. CONCLUSION: The system has been accepted by both residents and surgeons and has addressed the important components of resident in-training evaluation, namely, evaluation on a case-by-case basis, timely feedback, and self-assessment of resident performance.

A computer-based training program has been devised to promote better understanding of the recently revised National Institute for Occupational Safety and Health (NIOSH) test guidelines applicable to methods requiring on-site sample collection and laboratory sample analysis of airborne toxic substances. A statistics section explains the basis of the NIOSH accuracy criterion (NAC); an experiments section provides details on the evaluation experiments; and a calculations section calculates method statistics based on data entered by the user. The statistics section graphically explains concepts such as the NAC and limit of detection, allowing the user to experiment with some parameters to see how the results are affected. This section also provides background material to show how some of the performance criteria evolved. The experiments section provides a summary of the experiments used to generate the data for method evaluation. The calculations section has several screens that work like customized spreadsheets for the entry of data collected during the laboratory evaluation of a method. A separate screen then calculates the precision (relative standard deviation) of analytical results at each of four concentrations, tests to see if the precision values are statistically homogeneous, and combines the homogeneous data for calculation of the relative standard deviation. It does the same for bias, and combines the precision with method bias to arrive at an estimate of method accuracy. Other screens in the calculations section facilitate the determination of method limit of detection and sample storage stability.
