Northwell Health Laboratories: The 10-Year Outcomes After Deciding to Keep the Lab.

CONTEXT.—: Northwell Health Laboratories were established in 1997, serving the Northwell Health system. In 2008, the health system considered minority entry into a joint venture with a commercial laboratory. Based on arguments made by Northwell laboratory leadership, the decision was made to retain full ownership of the laboratory. OBJECTIVE.—: To evaluate the 10-year outcomes of the 2008 decision and assess the value of a fully integrated laboratory service line for a regional health network. DESIGN.—: Ten-year outcomes were analyzed including financial, volume, and value-based activities. RESULTS.—: First, a fully integrated laboratory service line was created, with unified medical and managerial leadership. Second, Core Laboratory volumes and revenues grew at annualized rates of 4.5% and 16.0%, respectively. Third, hospital-based laboratory costs were held either constant, or grew in accordance with strategic clinical programs. Fourth, laboratory services were able to provide leadership in innovative system clinical programming and value-based payment programs. Fifth, the laboratories became a regional asset, forming a joint venture affiliation with New York City Health + Hospitals, and supporting distressed hospitals in Brooklyn, New York. Lastly, Northwell Health Laboratories have become a reputational asset through leadership in 2 consortia: The Compass Group and Project Santa Fe. CONCLUSIONS.—: The 10-year outcomes have exceeded projections made in 2008, validating the decision to retain the laboratories as a wholly owned system asset. The laboratories are now well positioned for leading innovation in patient care and for helping to drive a favorable posture for the health system under new payment models for health care.
