The Effect of the Neuman Systems Model on Eye Surgery Patients' Anxiety: Randomized Controlled Trial.

Purpose: Perioperative anxiety is prevalent among patients undergoing eye surgery. This study aimed to evaluate the effectiveness of the Neuman Systems Model (NSM) in reducing preoperative surgical anxiety by targeting intrapersonal, interpersonal, and extrapersonal stressors.

Design: This was a single-center, randomized controlled trial.

Methods: A total of 70 patients were randomly assigned into 2 groups. The patients in the intervention group (n = 35) received NSM-based intervention and the patients in the control group (n = 35) were subject to a routine care before the surgery. Anxiety levels were measured using the Spielberger State-Trait Anxiety Inventory before and after the intervention in both groups.

Findings: There is no significant statistical difference in State and Trait anxiety levels before intervention in both groups (P > .05). In the intervention group, the mean State anxiety score significantly decreased from 47.82±3.47 to 42.22±3.20 (P < .001), while no significant change was observed in the control group (47.88±3.75, P = .156). Similarly, the Trait anxiety score in the intervention group decreased from 49.05±3.79 to 47.22±3.30 (P < .001), with no significant difference in the control group (49.25±3.94, P = .431).

Conclusions: The results demonstrated the effectiveness of implementing the NSM-based intervention in reducing preoperative anxiety in eye surgery patients. Therefore, it is recommended that this model be used to reduce anxiety in clinical settings.
