Hospitals spent less on inpatient care when more nearby outpatient organizations used electronic health records, according to a study that tracked 4,581 U.S. hospitals over 13 years. The paper appeared in Information & Management in June.
The researchers matched hospital data with records from 67,915 outpatient care organizations. They estimated that a one-standard-deviation rise in nearby electronic-record adoption was associated with $1.6 million in lower inpatient costs at a hospital. A standard deviation describes a change relative to the spread of values in the study.
The authors point to information sharing as a possible link. When clinics and hospitals can exchange records, hospital staff may have access to more complete information without repeating administrative work. The study examined system-level costs, not whether a particular tool improved an individual’s care.
The figure is a statistical association, not a guaranteed saving or proof that electronic records caused costs to fall. The result also comes from U.S. hospitals and may not transfer directly to health systems with different funding and technology rules.
The research adds evidence to a practical question for hospital IT: whether digital systems create more value when neighboring organizations can connect to them. The study measures costs over time, but it cannot isolate every local change that may have affected spending.
