Is HIT a hit? The impact of health information technology on inpatient hospital outcomes

In an effort to eliminate inefficiencies in the US health care sector, policymakers have made a concerted effort to encourage hospitals and physicians to adopt health information technology (HIT) systems. Using a unique data set on HIT adoption and health outcomes in New York State, we conduct a hospital-level analysis identifying the impact of adopting HIT on inpatient outcomes (rates of adverse drug events and severity-adjusted mortality). Unlike previous studies, the patient population is not restricted to Medicare patients, but covers all ages and insurance types. After controlling for unobserved hospital quality and endogenous HIT adoption, our results suggest that a hospital’s severity-adjusted mortality decreases by 0.3 percentage points. When restricted to the Medicare patients, we find HIT adoption lowers a hospital’s severity-adjusted mortality rate by 0.5 percentage points. We find HIT to have no significant effect on the rate of ADEs.
