Follow-up of vasectomy using medical record linkage.
Goldacre MJ., Clarke JA., Heasman MA., Vessey MP.
The authors report the findings from an on-going of 1764 vasectomized men followed up by means of the Scottish medical record linkage system for a total of 4500 man-years after operation. The authors view the results so far as reassuring regarding the safety of vasectomy, although the mean length of follow-up (2.6 years) is still short. The study will continue. Some features of this method of follow-up are described and discussed.
