The article examines the association between hospital readmission and mortality rates for cardiac patients who were presented with clinical case of acute myocardial infarction, heart failure and pneumonia. It highlights the impact of quality of medical care provided by health care centers in resolving the risk associated with cardiac patients. The Centers for Medicare & Medicaid Services in the U.S. on the basis of a cohort analysis revealed that differences in performance of hospitals and diagnostic parameters implied by hospital were of immense use in determination of readmission rate and mortality rate of cardiac patients.

The article discusses a study which described the temporal changes in length of stay, discharge disposition, and short-term outcomes among older U.S. patients hospitalized for heart failure. The observational study examined 6,955,461 Medicare fee-for-service hospitalizations for heart failure between 1993 and 2006. The researchers found that the mean length of stay decreased from 8.81 days to 6.33 days between 1993 and 2006. The importance of examining an episode of acute care during a standardized period of assessment is also highlighted by the study.
