    Purpose: This study aimed at evaluating the educational value of the morbidity mortality meeting and benefits obtained from it so as to implement changes that can improve it.
    Methods: Surgeons (n=13) at a university hospital responded anonymously to a questionnaire which was structured to monitor the educational activity of the morbidity mortality meeting. They indicated their perceptions on a five-point scale (very poor, poor, fair, good and very good). Depending on the results of the first questionnaire, these changes were made: 1) Standardisation of the notice of the meeting 2) Organization of the meeting 3) Review of the literature on the specific problems encountered. The participants were not aware of the results of the first questionnaire. Nine weeks later, the same questionnaire was repeated (n=12). Mann Whitney test was used to compare the ratings of the two questionnaires.
    Results: The attributes which showed significant improvement between the first and second questionnaires were a) organization (p=0.004; (median (range) 3 (2-5) compared with 5 (3-5)) b) knowledge is up-to-date (p<0.005; (median (range) 3 (2-4) compared with 4 (3-5)), c) discussion related to the problem (0.01; (median (range) 3 (1-4) compared with 4 (3-5)) and d) notice of the meeting (p< 0.026; (median (range) 3 (2-4) compared with 4 (2-5)),
    Conclusions: This study showed that specific actions can improve the educational quality of the morbidity mortality meeting.

    Comparative surgical audit to monitor quality of care should be performed with a risk-adjusted scoring system rather than using crude morbidity and mortality rates. A validated and widely applied risk adjusted scoring system, P-POSSUM (Portsmouth-Physiological and Operative Severity Score for the enUmeration of Mortality) methodology, was applied to a prospective series of predominantly general surgical patients at the Sarawak General Hospital, Kuching over a six months period. The patients were grouped into four risk groups. The observed mortality rates were not significantly different from predicted rates, showing that the quality of surgical care was at par with typical western series. The simplicity and advantages of this scoring system over other auditing tools are discussed. The P-POSSUM methodology could form the basis of local comparative surgical audit for assessment and maintenance of quality care.

    BACKGROUND: The Physiological and Operative Severity Score for the enUmeration of Mortality and morbidity (POSSUM) is an objective and appropriate scoring system for risk-adjusted comparative general surgical audit. This score was devised in the UK and has been used widely, but application of POSSUM to centres outside the UK has been limited, especially in developing countries. This prospective study validated its application in a surgical practice with a different population and level of resources.
    METHODS: All general surgical patients who were operated on under regional or general anaesthesia as inpatients over a 4-month period at Sarawak General Hospital in 1999 were entered into the study. All data (12 physiological and six operative factors) were analysed for mortality only with the POSSUM equation and the modified Portsmouth POSSUM (P-POSSUM) equation. Comparisons were made between predicted and observed mortality rates according to four groups of risk: 0-4, 5-14, 15-49 and 50 per cent or more using the 'linear' method of analysis.
    RESULTS: There were 605 patients who satisfied the criteria for the study. Some 56.7 per cent of patients were in the lowest risk group. The POSSUM predictor equation significantly overestimated the mortality in this group, by a factor of 9.3. The overall observed mortality rate was 6.1 per cent and, again, the POSSUM predictor equation overestimated it at 10.5 per cent (P < 0.01). In contrast, the observed and predicted mortality rates for all risk groups, including the predicted overall mortality rate of 4.8 per cent, were comparable when the P-POSSUM predictor equation was used.
    CONCLUSION: The POSSUM scoring system with the modified P-POSSUM predictor equation for mortality was applicable in Malaysia, a developing country, for risk-adjusted surgical audit. This scoring system may serve as a useful comparative audit tool for surgical practice in many geographical locations.

    Though peripheral arterial disease is not as common as in the Western countries, abdominal aorit aneurysm (AAA) is the most frequent arterial problem in Malaysia. A prospective study was made of 100 consecutive patients who presented with AAA to the author between January 1986 to September 1988 (31 months' period). There were 88 males and 12 females. The age range was 47-90 years, mean = 68.7. All the major ethnic rates were equally affected. The sizes of the AAA were documented by ultrasonography and the diameters ranged from 3-10 centimetres, mean = 5.8. Aneurysmectomy was performed on 58 patients, 17 of which were emergencies for ruptured AAA. The operative mortality for elective surgery was 2 percent, but that for emergency surgery was 47 percent. Ten patients refused surgery and 28 were not offered an operation. The true incidence of AAA is likely to be much higher than the number of patients referred for treatment. Many cases are not diagnosed or referred for treatment. Many cases of ruptured AAA died at home or in peripheral hospitals without a diagnosis being made. It is estimated that an AAA is present in 17,000 persons in Peninsular Malaysia. The risk of elective surgery is significantly lower than that of emergency. The overall mortality for ruptured AAA is even higher at about 99 percent. Furthermore, AAA is a benign disease and after surgery the patients return to their normal life expectancy. It is recommended that patients with AAA of five centimetres or more should be advised surgery if premature death is to be avoided.
