Preventable hospitalization is defined as hospitalization of patients in healthy conditions with the possibility of treatment by outpatient care. Preventable hospitalizations are seen commonly in patients aged 65 years or older. Congestive heart failure and chronic obstructive lung disease are among the leading causes of preventable hospitalizations. Chronic diseases, geriatric syndromes, and care challenges are the most important risk factors. The decrease in the rate of preventable hospitalizations may make important contributions for adopting better and improved health practices, ensuring cost-effectiveness, and effectively utilizing resources. To prevent these hospitalizations, the follow-up of patients at risk with the inter-disciplinary team, the implementation of advanced discharge planning during discharge, the control of used drugs after discharge, and care support out of hospital are needed.
