Effect of Physician IT Use on Practice Performance.

The role of information technology (IT) remains important within the medical community. However, little is known about the extent to which practicing physicians improve practice performance by having and utilizing IT at the national level. The present study, analyzing a national physician survey (n = 4,720), seeks to explore associations of IT availability and utilization with practice performance at the national level. The multivariate regression analysis results suggest that patient information IT functionality upholds physician advantages in annual income but prescription drug IT functionality was reversely linked to annual income. We also found a negative association of patient information IT functionality with patient visit volume. Our study results revealed mixed findings. Not all IT functionalities would offer benefits to practicing physicians. Our data suggest that patient information IT functionality can moderate cost concerns related to IT investment among providers.
