Driven by the compulsion to improve the evident paucity in quality of care, especially in critical access hospitals in the United States, policy makers, healthcare providers, and administrators have taken the advise of researchers suggesting the integration of technology in healthcare. The Electronic Health Record (EHR) System composed of multiple components has been proposed as one technological solution to improve the quality of care. Each of the components of an EHR system maps into a meaningful use criterion defined by the Department of Health and Human Services as a means to improve quality. The quality of care as measured by 30-day mortality rates in rural critical access hospitals is lagging when compared to the urban hospitals. EHR component data were obtained from Health Information Management Systems Society and the 30-day mortality rate data were acquired from the Center for Medicaid and Medicare Services. The study sample included all the critical access hospitals in the United States. After the elimination of records with incomplete data, 1,023 (77%) records were remaining out of the 1,322 records on critical access hospitals. The study utilized a quantitative, exploratory, non-experimental, retrospective research method to investigate the correlation between three prominent individual EHR component implementations' impact on the quality of care as measured in 30-day mortality rates for patients suffering with acute myocardial infarction, congestive heart failure, and pneumonia in critical access hospitals. Spearman's correlation coefficient was calculated revealing no correlation between inputting data through Computerized Provider Order Entry, recording and charting changes in vital signs, and maintaining an up-to-date problem list, EHR components, and the 30-day mortality rates. The findings suggest further examination of the correlation of other EHR components and quality of care in critical access hospitals as well as exploration of other means of measuring quality of care.
