Public Health Laboratories and Health System Change: Executive Summary. Reductions in testing volume


PHLs serving as providers of testing services for Medicaid populations have seen the number of specimens submitted to them decrease as MCOs have taken responsibility for the care of Medicaid patients. In some cases, reductions have been significant enough to stimulate operational change within the PHL. These reductions in test volume may be due to MCOs using their preferred private laboratory vendors, and possibly to decreased testing on the part of the MCOs. Although this was the most common "adverse" outcome reported (noted by roughly a third of the PHLs), it did not appear to have much of a substantial impact on most of the labs we studied.
