Although healthcare IT has the potential to improve the healthcare quality, achieving benefits from implementation of healthcare IT may be a lengthy process, according to a study in Health Affairs.

Jeffrey S. McCullough, PhD, assistant professor in the division of health policy and management at the University of Minnesota School of Public Health in Minneapolis, and colleagues measured changes in the quality of care following adoption of EHR s among a national sample of 3,401 nonfederal, acute-care U.S. hospitals from 2004 to 2007.

Multivariate regression techniques measured the effect of healthcare IT on six quality measures independently across academic and nonacademic hospitals: ACE inhibitor/ARB use, smoking cessation advice (for heart failure patients), pheumococcal vaccination, blood culture precedes antibiotic, smoking cessation advice (for pneumonia patients) and most appropriate antibiotic for pneumonia patients.

According to the authors, academic hospitals have been the leading adopters of healthcare IT and the setting for much of the healthcare IT value literature. Academic hospitals also differ from other hospitals in their case-mix and organization. Consequently, it is crucial that we understand whether and how the academic context influences healthcare IT value.

Average quality was higher for hospitals with EHRs and CPOE for all sampled hospitals, the report stated. “However this difference was statistically significant only for pneumococcal vaccine administration and use of the most appropriate antibiotic for pneumonia,” McCullough and colleagues reported.

For academic hospitals, the difference in quality following IT adoption was larger than it was for hospitals on average, the study found. Significant improvements were found for pneumococcal vaccine administration (6.1 percentage point) and the most appropriate initial antibiotic use for pneumonia patients (3.7 percentage points).

The report found that the effects of healthcare IT for academic hospitals were about threefold larger than the effects for hospitals on average. Healthcare IT is correlated with quality improvement in nonacademic hospitals. Although positive for each measure, the differences are small and not statistically significant.

The authors concluded that if context dependence is caused by differences in technology and implementation, then the average U.S. hospital will generate large returns only when it fully implements comprehensive EHR systems. Under these conditions, meaningful use criteria will be essential to generating widespread returns from healthcare IT. If the meaningful use is set low, substantive returns from widespread healthcare IT adoption should not be expected.
