Reasons for Hospitalisation among Patients with Diabetes in a Secondary Care Hospital in South India: A Retrospective Study.

Background: Type 2 diabetes mellitus is a rapidly emerging non-communicable disease in India. It is associated with many life-long complications and higher rates of hospitalisations. The characteristics and reasons for hospitalisation among individuals with diabetes have not been documented in India. Such a study would direct policy makers in implementing prevention and education strategies and economic changes as needed. Aim and Objectives: The study aimed to study the characteristics and causes of admission of patients with diabetes admitted to a secondary care unit in South India. Methods: Aretrospective observation study of inpatient records of patients with diabetes aged 18 years and above admitted between January to December 2019 in a secondary care unit was done. The details of patient demographics, reason and outcome of admission were retrieved manually from paper-based patient records. Descriptive analysis was done using SPSS version 23. The study was approved by the Institutional Review Board of the institution. Results: Among the 479 admissions of patients with diabetes during 2019, the mean age of the admitted patients was 57.75 years. The majority of them had only one admission, 15% had re-admissions in the same time period. Approximately 78% of the admitted patients had one or more co-morbidities, 44.6% had hypertension as a co-morbidity. The principal cause of admission was infections (45%), followed by metabolic and endocrine causes (13.5%), cardiovascular disease (10.9%) and renal disease (7.96%). More than 80% of the admissions had a favourable outcome and were discharged. Conclusion: This retrospective study demonstrated that the most common reason for admission among patients with diabetes to a secondary care unit in South India was infection. Many infections are preventable with effective treatment for diabetes and health education. Patients bear the costs of routine treatment for diabetes which is a fraction of the direct cost of hospitalisation and can drive them to huge economic losses. Therefore, interventions to promote standard treatment by primary and secondary care health professionals and self-awareness among patients need to be done to prevent hospitalisations.
