摘要

Objective: To compare the results of capture–recapture estimates and exhaustive follow-up in identifying thenpercentage of UK medical graduates who subsequently worked in the British National Health Service (NHS).nMethods: Postal questionnaire survey of all UK-trained doctors who graduated in 1974, with up to three remindersnsent to non-respondents. Further exhaustive tracing of non-respondents to obtain whole population estimates ofnnumbers in the NHS. Capture–recapture estimation of numbers working in the NHS, using survey data andnDepartment of Health employment records, for comparison with results from exhaustive tracing.nResults: A total of 85.3% (1460/1712) of respondents were working in the NHS, but further exhaustive tracing ofnnon-respondents revealed that only 75.9% (1758/2317) to 79.2% (1835/2317) of the whole cohort were in the NHS.nBy comparison, capture–recapture analysis estimated that 76.9% (1781/2317) of the cohort were in the NHS (95%nCI: 75.9% to 78.0%).nConclusions: Survey data alone overestimated the percentage of the whole cohort in the NHS. Capture–recapturenestimates were very similar to those obtained by exhaustive tracing but were obtained more quickly and for muchnless clerical effort.
