[Is continuing medical education under suspicion of corruption? Contribution to the discussion by the Committee for Quality Preservation of the Swiss Society of Gynaecology and Obstetrics]. / Arztliche Fortbildung unter Korruptionsverdacht?. Diskussionsbeitrag der Kommission Qualitätssicherung der Schweizerischen Gesellschaft für Gynäkologie und Geburtshilfe.

The requirements laid down by law and by the medical profession itself with regard to continuing medical education have recently been tightened. The cost of good training is high, both in time and money. Sponsoring, especially by the pharmaceutical industry, has helped to keep costs down for individual participants. The question of a tariff system for the payment of compulsory training is now being raised. Rates have been set to ensure that, in the future, indirect costs are covered. In the event of a full tariff-based payment of costs being introduced, various disadvantages could be expected both for participants and the quality of the training. Changes in Swiss criminal law and the new medicines act do not forbid sponsoring, but they do call for rules of professional ethics and of personnel law in public hospitals governing behaviour in respect of funding by sponsors. Various sponsoring models are conceivable with differences in allocation to organizers, individual participants or distribution via a pool system. There are strong arguments in favour of continuing the existing practice of mixed funding by participants and sponsoring, provided that it is subject to certain rules of transparency. What is lacking to date is a political decision on the issue of funding for continuing medical education.

Impact of the reduction of anaesthesia turnover time on operating room efficiency.

BACKGROUND AND OBJECTIVE: We investigated whether an increase in anaesthesia staffing to permit induction of anaesthesia before the previous case had ended ('overlapping') would increase overall efficiency in the operating room. Hitherto, the average duration of operating sessions was too long, thus impeding the timely commencement of physicians' ward duties. METHODS: The investigation was designed as a prospective, non-randomized, interrupted time-series analysis divided into three phases: (a) a baseline of 3.5 months, (b) a 2.5 month intervention phase, in which anaesthesia staffing was increased by one attending physician and one nurse, and (c) a further 2 months under baseline conditions. Data focussed on process management were collected from operating room staff, anaesthesia personnel and surgeons using a structured questionnaire collected daily during the entire study. RESULTS: Turnover time between consecutive operations decreased from 65 to 52 min per operation (95% CI: 9; 17; P = 0.0001). Operating room occupancy increased from 4:28 to 5:27 h day-1 (95% CI: 50; 68; P = 0.005). The surgeons began their work on the ward 35 min (95% CI: 30; 40) later than before the intervention and their overtime increased from 22:36 to 139:50 h. CONCLUSIONS: The time between surgical operations decreased significantly. Increased operating room efficiency owing to overlapping induction of anaesthesia allows more intense scheduling of operations. Thus, physicians and nurses can be released to spend more time with their patients in the ward. Improving the efficiency of the operating room alone is insufficient to improve human resource management at all levels of a surgical clinic.

Quality assessment in gynecology and obstetrics. Projects and experience in Switzerland.

The first steps in quality assessment of results of performance in gynecology and obstetrics were taken by the Swiss Association of the OB/GYN Clinics of the Swiss Society of Obstetrics and Gynecology in the 1980's. Currently, medical data of more than 800,000 patients are available, allowing a good comparison of the quality of results. Concerned that purchasing coverage for health services was made exclusively on the basis of cost, resulting in lower public health quality, the Swiss Society of OB/GYN set up a Board of Quality Assessment in 1995. Not only the quality of results, but also the quality of indications, structures and processes are considered by using a modified Donabedian model. Moreover, standardized patient information forms have been worked out for 15 gynecological and five obstetrical operations. Since hysterectomy is the most common major gynecological operation in Switzerland, the evaluation of the quality of the indications is of substantial interest. Guided by the RAND Appropriateness Method, criteria for quality assessment with respect to appropriateness and necessity of hysterectomy have been drawn up. Swiss guidelines and 125 different clinical scenarios are defined by a panel of 22 OB/GYN experts. The aim of this project is to offer an interactive second opinion system, called "Swiss Guidelines for Hysterectomy", and anonymous self-assessment of quality. Appropriateness and necessity of medical procedures have to be defined by medical professionals providing a proper balance between the patient's desires and financial demands.

Single-use versus reusable laparoscopic surgical instruments: a comparative cost analysis.

OBJECTIVE: Our purpose was to determine and compare the total annual costs for reusable and single-use laparoscopic instruments. STUDY DESIGN: Records were kept over a 12-month period of all laparoscopic operations (performed only with reusable instrumentation), the surgical instruments used, depreciation costs, and all associated expenses (repairs, maintenance, replacements, cleaning, sterilization, wages). The total cost was then calculated and compared with the total cost (purchase price plus disposal fees) that single-use instruments would have caused for the same operations. RESULTS: The total cost for single-use instruments would have been more than seven times that for reusable instruments. CONCLUSION: We have decided to continue using reusable instruments for most of our laparoscopic operations. However, single-use instruments are used in situations in which they present a definite advantage. A proper balance is thus sought between the importance of cost factors, on the one hand, and the recognition of the need for the best instrument available for certain procedures, on the other.

Assessment of effect of photosensitizers on cytotoxicity of photodynamic therapy in human breast cancer cell cultures.

BACKGROUND: Photodynamic therapy (PDT) might be of clinical value for patients with breast cancer with local recurrences or metastasis. However, there is a need for improved photosensitizers that are effective in combination with laser light and have few, if any, side-effects. We evaluated in vitro the effectiveness of a second generation photosensitizer by testing the influence of laser light on cell cultures of a human breast carcinoma cell line, incubated with meta-tetrahydroxyphenylchlorin (m-THPC) (= Temoporfin). EXPERIMENTAL DESIGN: Five thousand MCF-7 cells were plated in 96-well plates. Forty-eight hours before laser treatment, the cells were plated to achieve a monolayer configuration. Twenty-four hours after plating, they were incubated with m-THPC. On day 6 after treatment with m-THPC we lysed the cells to extract the intracellular ATP that correlates with the number of living cells. The ATP-CVA was used to assess the cytotoxicity of the tested photosensitizer m-THPC at various concentrations and the relevant laser light alone prior to their combination after six days of culture. RESULTS: We found a dose-response for m-THPC alone ranging from 2 to 16 micrograms/ml. The calculated inhibition concentration to produce 50% cell kill (IC50) was 4.55 micrograms/ml. We also observed a very low cytotoxicity for laser irradiation alone but a very strong cell kill for the combination of m-THPC together with laser light. CONCLUSIONS: PDT gave almost total cell kill at m-THPC concentrations that are not toxic in vitro.
