Patient readmission and support utilization following anterior temporal lobectomy

The aim of this study was to examine factors precipitating patient readmission, following anterior temporal lobectomy (ATL) for refractory epilepsy. A second aim was to explore the use of hospital outpatient and community support services ('outpatient services') by this patient population. These aims served the more general goal of identifying patients most likely in need of services additional to those routinely provided by our Seizure Surgery Follow-up and Rehabilitation Programme. The medical records of 100 consecutive ATL patients were retrospectively examined for the incidence and diagnoses precipitating acute readmission, and the utilization of additional outpatient services. Twenty-one patients (21%) required readmission post-ATL, totalling 47 readmissions between them. Psychiatric diagnoses were the most prevalent (53%), including anxiety, depression and/or post-ictal psychosis. Epileptological diagnoses were the other main precipitant (28%). Additional outpatient services were predominantly utilized for ongoing psychological support. Of the 21 patients requiring readmission, 10(10%) also needed additional outpatient services. These patients were predominantly female or unemployed, in contrast to male or employed patients who tended to require readmission only. Seventeen patients (17%) were maintained within the community using additional outpatient services only. Characteristics of these patients included disrupted family dynamics, limited social networks, and/or a psychiatric history. These patients were also more frequently beyond the 24-month follow-up period of the programme. A profile of patients most in need of additional support services can be constructed to assist team planning of proactive management strategies for the rehabilitation phase of ATL.
