BACKGROUND: Behavioral symptoms among postoperative patients with intracranial tumors and distress among caregivers are common. OBJECTIVES: This article aimed to assess the effectiveness of a brief nurse-led intervention on behavioral symptoms of postoperative patients with intracranial tumors and distress of their caregivers. METHODS: A randomized controlled trial was conducted on 80 patients with intracranial tumors and their family caregivers in a tertiary care institute in India. A brief nurse-led intervention was provided in the form of individual counseling, and a pamphlet was given to patients and caregivers in the experimental group at the time of discharge. Behavioral symptoms of patients and distress of caregivers were assessed. FINDINGS: Patients in the experimental group had significantly fewer behavioral symptoms and less severity of behavioral symptoms as compared to the control group. Caregivers in the experimental group had significantly less severity of distress as compared to the control group.
