[Sciatica and other low-back disorders in private practice: extent of the problem and therapeutic approaches].

Using data collected by INSERM in a 1975 survey among French general practitioners and specialists in private practice, the reporting of sciatica and low back pain (LBP) was studied, as well as doctors' diagnoses and therapeutic approaches. Only 0.7% of patients were reported as having sciatica, while 2.8% were reported with LBP. These percentages suggest, respectively, 1.5 and 6.5 million consultations with private practitioners. The prevalence of sciatica was estimated at 8%. There was no urban-rural difference in the consultation rate; three-quarters of the patients were seen by GPs. The frequency of LBP was higher among the employed, particularly among manual workers. Referrals for additional examinations were nearly twice as high for sciatica as for LBP. GPs prescribed more medicines, and more sick leave, than specialists, but made fewer referrals for additional examination, probably because the patients seen were different, or were at a different stage of disease. It is concluded that the formulation of standards of care specific to each level of care might be useful.
