Effectiveness of Roy Adaptation Model-Based Cognitive Stimulation Therapy in Elderly Patients with Non-Small Cell Lung Cancer Undergoing Curative Resection.

ABSTRACT

This study aimed to investigate the effects of a Roy adaptation model (RAM)-based cognitive stimulation therapy (CST) intervention on elderly patients diagnosed with primary non-small cell lung cancer (NSCLC) undergoing curative resection. A total of 280 patients diagnosed with primary NSCLC were randomized into RAM-based CST group and control group. Outcomes were assessed at three intervals pre-surgery, discharge, and one-month post-discharge. Cognitive function was evaluated using Mini-Cognitive test. Postoperative delirium prevalence was determined within 48 hours post-surgery using Nursing Delirium Screening Scale. The Hospital Anxiety and Depression Scale evaluated anxiety and depression symptoms, while Quality of Life (QoL) was assessed via Short Form-36 (SF36) Health Survey. The RAM-based CST group demonstrated significantly higher Mini-Cog test scores than the control group upon discharge and post-intervention. Patients with RAM-based CST exhibited a decrease in postoperative delirium compared to the control group. The RAM-based CST intervention yielded an improvement in anxiety and depression at discharge and 1-month post-discharge compared to preoperative levels. Additionally, the RAM-based CST group exhibited substantial enhancements in SF36 subcategory scores at 1-month post-discharge compared to pre-surgery. At post-intervention, the RAM-based CST group demonstrated significantly higher scores than the control group across various health-related domains, including role limitations due to emotional problems, mental health, general health perception, bodily pain, and role limitations due to physical problems. The RAM-based CST intervention in elderly NSCLC patients undergoing curative resection yielded significant enhancements in cognitive function, reduced delirium incidence, improved emotional well-being, and better QoL postoperatively.
