The Effect of Video-Assisted Education on Pain, Anxiety, and Vital Signs in Patients With Chest Tubes: A Quasi-Experimental Study

Abstract

Objective: To evaluate the effect of video- plus brochure-assisted education versus brochure-only education on pain, anxiety, and vital signs in patients undergoing chest tube insertion. Methods: This quasi-experimental study included 78 patients (experimental [video + brochure]: n = 39; control [brochure only]: n = 39). Data were collected using a patient identification form, the 11-point Numerical Rating Scale (NRS) for pain, the Beck Anxiety Inventory (BAI), and a vital signs monitoring chart. Pain and vital signs were assessed preoperatively, at 1, 8, and 24 hours postoperatively, and immediately and 1 hour post-chest tube removal. Results: The sample comprised 51 male (65.4%) and 27 female (34.6%) participants (mean age, 60.4 years). Preoperative mean NRS scores were significantly higher in the control than the experimental group (P = .045); however, postoperative pain scores were similar (P = .26). The absolute postoperative pain increase was significantly smaller in the control group (P = .042). At 8 hours postoperatively, the control group had significantly lower body temperature (P = .004) and lower diastolic blood pressure (P = .03) than the experimental group. A weak negative correlation was found between BAI scores and respiratory rate immediately following chest tube removal across the entire cohort (r = -.23, P = .04). At 1 hour after surgery, moderate positive correlations were observed between BAI and NRS scores in the control group (P < . 001),  whereas no such relationship existed in the experimental group (P = .54). Conclusions: Multimedia education did not significantly reduce overall postoperative pain or anxiety versus brochure-only education but significantly influenced body temperature and diastolic blood pressure at 8 hours post-surgery.
