—One of the primary intentions of the Clinical Laboratory Improvement Amendments of 1988 (CLIA 88)1 was to improve the quality of physicians' office laboratories (POLs). Although a few states mandated quality standards for POL operation,2 most states, including Minnesota, did not regulate POLs. Because little was known about Minnesota POLs and how they might be affected by CLIA, we surveyed a cohort of randomly selected Minnesota POLs in 1991 (before the publication of the final 1992 regulations) and resurveyed the cohort in the summer of 1993 (18 months after their publication). In this letter, we present the changes in quality practices that followed CLIA 88.In 1991, we used the most recent American Medical Directory of the American Medical Association and randomly selected general practice, family practice, and general internal medicine physicians in Minnesota. Physicians associated with clinics with less than 35 physicians were asked
