Introduction – Non-completion of treatment poses a significant challenge for professional healthcare workers in a tertiary care Centre with greater risk in psychiatric patients where capacity is often compromised. Non-completion of treatment also has adverse consequences for the patient, his caregiver, and the community he belongs. Health services, healthcare workers, and other patients lowered staff morale, denied the service to others who could have used it, and disruption of ward discipline along with compromised cost efficiency depleting hospital resources. We aim to study the sociodemographic and clinical factors that could affect the non-completion of treatment in hospitals and enable them to tailor services in a better way. Methods - This study was performed in a tertiary care hospital in Indore, India. Treatment records of 49 inpatient admissions from August 2020 to July 2021 were identified from the medical record department of the hospital which absconded from the premise. Records were assessed for sociodemographic and clinical details and analyzed using appropriate tools. Results- Among 673 admissions during the specified period, 49 patients absconded with a rate of 7.1%. Most of them were male, from a younger age, Hindu by religion, belong to a nuclear family, and live within a 100 km of radius. Most Patients with bipolar affective disorder and schizophrenia & related psychosis had more tendency to abscond compared toother psychiatric illnesses. Conclusions – Socio-demographic and clinical variables have a significant correlation with non- completion of treatment and identification of high-risk groups or red flags during the admission process can help achieve higher completion rates.
