Quality-of-care assessment. I. Outpatient management of acute bacterial cystitis as the model.

A study was undertaken to determine whether a process audit of outpatient medical care would correlate significantly with the outcomes of care and thus prove to be a valid method for assessing the quality of medical care in the outpatient setting. Acute bacterial cystitis in women was selected as the model for study. A series of 42 cases was reviewed by retrospective analysis of patient records supplemented by follow-up interviews and collection of a follow-up urine culture from each patient to document the outcome of treatment. No positive association was demonstrated between the processes for satisfactory care selected by the expert criteria committee and the observed outcomes. Reasons for this failure in the present study and for deficiencies of the process audit method in general are discussed.
