Incomplete or inaccurately filled fatal case documents are often returned to the hospital by higher headquarters, causing delay in the completion of procedural formalities. A mathematical model was developed to identify those fatal case documents which are at an increased risk of being returned so that the corrective action may be taken a priori. The data was subjected to a multiple logistic regression analysis. Diagnostic test characteristics were worked out and a Receiver Operating Curve analysis was done to find out optimum operating points on the slope, and the following mathematical rule was developed: MJAFI 1998; 54: 47-48 "

A prospective study on the growth of bacteria on certaiil commonly used anaesthetic equipment was undertaken in a large teaching hospital with a view to assess the effectiveness of disinfeCtion/sterilization procedures. Samples for microbiological assessment were drawn by the worker using standardised procedures and tested in the laboratory by a microbiologist, blinded to the type ofsample. Criteria for growth positivity was taken as > 25 colony forming units. A total of 90 observations were taken. 30 each for 'before use', 'after use' and 'after disinfection'. Overall 54.6% of the equipment showed growth "before use" with maximum growth being seen in Suction catheters (66.6%) and Guedal airways (60.0%). On the other hand, the proportion of equipment showing growth "after use" was quite high (84.6%), with suction catheters and endotracheal tubes showing 90.0% growth each. There was significant difference as regards "before" and "after" use growth on Endotracheal tubes, Guedel airways and Face masks (p < 0.05). Analysis of growth "after" disinfection" revealed that the probability of growth remains as high as 70% in suction catheters (95% CI=54% to 86%) and 60% in laryngoscopes (95% CI=43% to 78%). The study revealed gross inadequacies in methods of disinfection being followed at present. JAFI1998;54:188-191
