Intensity of care and better outcomes among hemodialysis patients: a role for the Medical Director

Abstract

The Medical Director is responsible for all levels of quality patient care in the facility as mandated by the 2008 revision of the Medicare Conditions for Coverage of dialysis facilities. He/she is the leader and primary individual tasked with ensuring that facility processes are in place to meet or exceed key quality goals or adopt new ones and prioritize them appropriately-all to drive improved facility performance, particularly the ultimate outcomes of morbidity and mortality rates. Management of vascular access, dialysis dose, mineral metabolism, acid-base balance, sodium and fluid management, anemia, among other aspects of care, have representative intermediate clinical outcomes that are often called "surrogate" or "process" measures-because they may reflect the quality of care delivery while impacting "primary" outcomes such as death and hospitalization. The proportion of dialysis patients within a dialysis facility meeting a selected group among these goals has become the standard "care process" metric since the 1990s. Evidence supports its use, in that graded improvements in the facility patients' primary outcomes have been documented as more patients in a facility achieved a greater number of these "process" goals. A caveat: these process measures do not represent overall quality by themselves because nonclinical processes also influence primary outcomes. Nevertheless, process improvement in meeting facility goals should be led by the Medical Director, particularly those with the strongest links to primary outcomes such as reduction of hemodialysis catheter exposure, forming the cornerstone of quality improvement efforts. Specific recommendations on how to effectively lead a care team to achieve these goals are discussed.
