A recent systematic review of health information technology

This updated systematic review on the effects of HIT recently appeared in the Annals of Internal Medicine. The focus was on meaningful use aspects, particularly clinical decision support and CPOE. A few studies looked at the effect of patients' access to their own EMRs. The results were mixed but tended to be positive. The vast majority of reports were on processes or very low level surrogates, with very few studies looking at meaningful clinical outcomes. Among those, however, were a couple of reports suggesting reduced mortality attributable to HIT.
