This study is quasi-experimental research using a two-group post-test design aimed at investigating the effects of a professional nurse-led weaning program combined with social support on the success rate and duration of ventilator weaning in critically ill medical patients. The sample included 60 critically ill medical patients who had undergone tracheal intubation and were on mechanical ventilation in a medical intensive care unit. They were divided into an experimental group and a control group, 30 patients each. The control group data were retrospectively reviewed from medical records of patients who received standard weaning care between December 2024 and January 2025. The experimental group received a ventilator weaning program developed based on the framework of the American Association of Critical-Care and social support based on the social support theory of Thoits. The sample was selected according to inclusion criteria and matched the control and experimental groups by age, gender, and physiological severity level (APACHE II Score). Data were collected using a personal information form, pre-weaning readiness assessment form, ventilator weaning success assessment form and weaning social support activities assessment form for relatives. The content validity was checked by 3 experts. Descriptive statistics, including frequency, percentage, mean, and standard deviation, were used. The difference in weaning success rate was compared with Chi-square test and the difference in weaning time after using the program compared with usual care was compared with the independent t-test.The results showed that the experimental group had a significantly higher ventilator weaning success rate (96.67 %) than the control group (70.00 %) (p=0.006) and had a statistically significant shorter mean duration of weaning (17.71 hours) than the control group (125.62 hours) (p<0.001).Therefore, the medical intensive care unit should implement a nurse-driven ventilation weaning program with social support, train and monitor and evaluate nurses’ use of these guidelines to enhance weaning success and reduce weaning duration.
