Doctors' characteristics and practice patterns in general practice: an analysis based on management of urinary incontinence.

Six case histories concerning female urinary incontinence were mailed to 191 randomly selected general practitioners (GPs) in Norway, of whom 139 (73%) replied. Great variations in suggested investigations and treatment were found between individual doctors. Four explanatory variables were examined: doctors' sex, years since graduation, urban/rural location, and GP specialization. GP specialists treated fewer patients adequately than non-specialists. Experienced female doctors instructed more patients in pelvic floor exercises, prescribed more oestrogens, referred more patients, and also indicated the possibility of surgery more frequently than their colleagues. Nevertheless, patient management is largely independent of a doctor's sex and age, practice location, and GP specialization.
