A new analysis published in Health Affairs finds that the implementation of health IT has had an overall positive effect on health care providers, Government Health IT reports. For the analysis, current and former staff members of the Office of the National Coordinator for Health IT surveyed 154 peer-reviewed articles published between 2007 and 2010. Researchers looked at how health IT affects access to care, efficiency, effectiveness of care, patient satisfaction and other factors. The study authors acknowledged two forms of bias in the study: Negative results are not reported as often as positive results; and A meta-analysis like this study considers all studies equally, regardless of sample size or design of the study (Perera, Fierce Government IT, 3/9). Of the 154 studies analyzed, researchers found that 92% reached conclusions indicating that health IT has a positive effect on patient care.
