title: Patient panel of underserved populations and adoption of electronic medical record systems by office-based physicians.
abstract: OBJECTIVE
  To examine the association between patient panels of underserved populations and adoption of electronic medical records (EMRs) among office-based physicians.
  
  
  METHODS
  Two thousand three hundred and twenty-six office-based physicians who responded and saw patients in the 2005 and 2006 National Ambulatory Medical Care Surveys.
  
  
  METHODS
  This study used a cross-sectional design. The unit of analysis was the office-based physician. EMR adoption was defined based on functionalities (No EMR, Limited, or Comprehensive). An EMR was considered to have "comprehensive" functionalities if it included computerized orders for prescriptions and tests, test results, and clinical notes by physicians. Patient panels of underserved populations were measured as proportions of racial/ethnic minorities, Medicaid recipients, or self-pay/no charge/charity care patients treated by a physician using the reported sociodemographic characteristics in patient records linked to their treating physicians. Data were analyzed using multivariate regression analyses controlling for other patient-panel characteristics and characteristics of physicians and their practices.
  
  
  RESULTS
  We found a negative association between the proportion of Hispanics treated by a physician and physician adoption of EMRs with "comprehensive" functionalities after adjusting for other covariates.
  
  
  CONCLUSIONS
  Physicians treating high shares of Hispanic patients may have lower access to EMRs with essential functionalities.
