RESUMO
The purpose of this study was to determine if there is a relationship between socioeconomic factors related to geography and insurance type and the distribution of anesthesia provider type. Using the 2012 Area Resource File, the correlation analyses illustrates county median income is a key factor in distinguishing anesthesia provider distribution. Certified registered nurse anesthetists (CRNAs) correlated with lower-income populations where anesthesiologists correlated with higher-income populations. Furthermore, CRNAs correlated more with vulnerable populations such as the Medicaid-eligible population, uninsured population, and the unemployed. Access to health care is multifactorial; however, assuring the population has adequate insurance is one of the hallmark achievements of the Affordable Care Act. Removing barriers to CRNA scope of practice to maximize CRNA services will facilitate meeting the demand by vulnerable populations after full implementation of the Affordable Care Act.
