Maryland Hospital Acquired Conditions (MHAC)
Main_Content
Overview
The MHAC program, which was first implemented for RY 2011, is based on a system developed by 3M Health Information Systems (3M) to identify potentially preventable complications (PPCs) using present-on-admission codes available in claims data. 3M originally developed specifications for 65 PPCs, which are defined as harmful events that develop after the patient is admitted to the hospital and may result from processes of care and treatment rather than from the natural progression of the underlying illness. For example, the program holds hospitals accountable for respiratory failure and pulmonary embolisms that occur during inpatient stays. These complications can lead to 1) poor patient outcomes, including longer hospital stays, permanent harm, and death; and 2) increased costs.Thus, the MHAC program is designed to provide incentives to improve patient care by adjusting hospital budgets based on PPC performance.
See the current rate year policy for additional information on the specific PPCs included in the payment program and how performance is converted to hospital revenue adjustments.
