Managing for total quality in a large laboratory. Some examples.

A large laboratory, processing more than 30,000 requisitions every 24 hours, provides a unique opportunity to document the value of selected approaches to managing for total quality. Proficiency test errors are an important subset of this database. They can provide a quality control manager with essential diagnostic information if data are analyzed in a systematic fashion. There is no benefit to performing proficiency tests in duplicate or in handling them in a manner different from patients. In fact, error rates can be higher when proficiency tests are handled in a special manner. Finally, error is decreased when technologists receive real-time feedback on how well the process is performing.

Normalization of the dexamethasone suppression test at discharge from hospital. Its prognostic value.

Fourteen patients with RDC diagnosis of primary, endogenous, major depressive disorder were studied in an inpatient setting. All were non-suppressors on the Dexamethasone Suppression Test on admission to hospital and were retested at discharge. Over 70% of patients continued to be non-suppressors at discharge, when in clinical remission. Four out of 14 patients converted to normal suppression. All 10 of the non-normalizers did poorly on follow-up: 3 patients committed suicide. All normalizers did well. Non-normalization of the DST at discharge from hospitalization may be more common than previously suspected and predicts poor clinical outcome.
