Factors Associated with Hospitalization for Type2 Diabetic Patients at a Teaching Hospital in Saudi Arabia

Increasing prevalence of diabetes all over the world intensifies the demand for health care services, and particularly for inpatient care. The present study aims at identifying factors associated with hospitalization for patients with type 2 diabetes mellitus at a teaching hospital in Saudi Arabia. To achieve the objectives of the study, comparison was made between hospitalized and non-hospitalized type 2 diabetic patients using a retrospective case-control design. Four categories of factors namely, socio-demographic, outpatient clinic, clinical and quality indicators were investigated to elicit their relation with hospitalization among type 2 diabetes patients. Univariate analysis and stepwise multiple regression analysis were employed. Hospitalization was found to be independently associated with male gender, frequent visitors of outpatient clinics other than diabetes clinic, patients with nephropathy and patients with HbAlc >= 7%. Limited number of cases and controls received the recommended ambulatory care for diabetes patients as evidenced by the marked low level of process of care indicators for diabetes patients. Conclusions and recommendations: Hospitalization was related to a limited number of factors many of which require better ambulatory care at outpatient clinics of the study hospital. It was recommended to continuously monitor the identified significant variables using the hospital electronic medical record system in order to target those patients at high risk for hospitalization.
