[Quality control of whole-body bone scintigraphy. Patient surveys].

INTRODUCTION: The quality of health care is but sparsely elucidated; surveys of complete patient courses hardly exist. We established and used benchmarks for a major nuclear medicine examination: whole-body bone scintigraphy. MATERIALS AND METHODS: The study material included 458 out of 512 consecutive examinations. Patients were referred by general practitioners (12%), practising specialists (16%) and hospital departments (72%). The survey dealt with waiting times and information provided, as judged by the patient, the referring physician and the Department of Nuclear Medicine (DNM) in relation to referrals, reporting and the passing on of the results to the patient. The DNM judged the quality of the examinations, and the referring physician assessed the implications for diagnosis and treatment. RESULTS: In 10% of the cases, the patient felt that the waiting time was unsatisfactory, as the referring physician might take up to 150 days to send the referral and because 11% had, after two months, still not been informed of the examination result. Supplementary tomography was used in 38 examinations (8%); of these, only one (3%) provided new evidence. Based on the examination results, the referring physician could make a diagnosis and/or wanted to change management for 61% of patients. CONCLUSION: Referrals were delayed mainly by the referring physicians, who often forgot to inform their patients of the examination results. Special admissions seldom yielded extra information. The examination result had important clinical implications in almost two thirds of patients.
