The Medical Review Committee


The Medical Review Committees are multidisciplinary bodies reflecting the multiple professions HAVEN serves. The second Wednesday evening of each month a medical review committee convenes to determine eligibility, terms and conditions for participation, status, compliance, and fitness to practice. The committee members will review readiness to assume responsibilities of narcotic access within scope of practice duties, grant approval for HAVEN to support reinstatement of DCP/DEA privileges, or revise contract terms. The Medical Review Committee may also find after careful review that HAVEN’s services are not required.

Reports and other records are deidentified, so committee members cannot identify the individuals seeking HAVEN’s support. The terms and conditions determined by the medical review committee become the health accountability contract entered into between the participant and HAVEN. If a professional disagrees with the Medical Review Committee determination, the professional may request that the Medical Review Committee reconsider. The professional may request review by the Oversight Committee. The Oversight Committee cannot override a Medical Review Committee decision, but the Medical Review Committee may reconsider a determination at the suggestion of the Oversight Committee. The professional may also elect to explore his or her option to work directly with the Department.

If there is a past or pending disciplinary action, felony conviction, or allegation of patient harm, the Medical Review Committee makes recommendations to the Department of Public Health and the Department will determine whether the professional is eligible to work with HAVEN.

The Medical Review Committee Members

Due to the sensitive and difficult decisions the medical review committee members must resolve, the identities of the Medical Review Committee members are kept confidential. 

Our sincere appreciation is extended to the dedicated members who donate their time to help their colleagues face challenges with dignity and respect.
