| Abstract: | A comparison was made between the indirect method of preparing a profession-specific working-life table and the direct method. The former uses data on the number of physicians per 1,000 population by age and assumes that the mortality rate for the profession is equal to that of the population as a whole. The latter method makes use of information on profession-specific mortality and on active and inactive status of living physicians. These two approaches were applied to physician data for the United States of America and it was noted that the direct method gives estimates of working life and total life expectancy that are significantly higher than by use of the indirect method. The likely magnitude and directions of the biases inherent in each of the methods are then discussed. A comparison is then made of the estimated working life for Colombian, French and US physicians using the indirect method. |
