The relationship of hospital process variables to patient outcome post-myocardial infarction Original Research Article

This study examined the hospital process variables of nursing care, medical care, information, and hospital environment, as evaluated by patients, in relation to their outcome post-myocardial infarction (MI). The sample included 68 hospitalized men and women, aged 29–92, who were diagnosed with an MI. At the time of discharge, they responded to four subscales of the Patient Judgment of Hospital Quality Questionnaire, which measured the hospital process variables, and the Revised Haussman and Hegyvary Outcome Criteria Instrument for Acute Myocardial Infarction, which measured patient outcome post-MI. Data also were collected from patient charts and nurses. Correlational analyses revealed statistically significant relationships between nursing care and patient outcome, and between hospital environment and patient outcome; neither medical care nor information correlated appreciably with patient outcome post-MI. Regression analysis indicated that nursing care was the only significant predictor of patient outcome post-MI.
