The efficacy of computer-assisted cognitive behavioral therapy (cCBT) on psychobiological responses and perioperative outcomes in patients undergoing functional endoscopic sinus surgery: a randomized controlled trial

BACKGROUND: Functional endoscopic sinus surgery (FESS) is required to minimize bleeding to maintain a clear operative field during surgery, so it is important to preoperative anti-anxiety and stable hemodynamics. Initial evidence suggests cognitive behavioral therapy (CBT) is effective to minimize surgery-related stress and to speed up recovery. The study aimed to evaluate the efficacy of a newly developed computer-assisted CBT (cCBT) program on surgery-related psychobiological responses in patients undergoing FESS. METHODS: Participants were allocated to a CCBT group (cCBT; n = 50) or a UC group (usual care; n = 50) by random number table. The State Anxiety Inventory (SAI), Patients Health Questionnaire-9 (PHQ-9), Athens Insomnia Scale (AIS), systolic blood pressure (SBP), diastolic blood pressure (DBP), and heart rate (HR) were assessed before intervention (T1), at 1 h before operation (T2), at postoperative 48 h (T3), and 96 h (T4: after intervention completed) respectively. The stress hormone was assayed at T1 and T2. The duration of surgery, anesthesia, and post-anesthesia care unit (PACU) were recorded. A satisfaction survey about nursing services was completed by participants before discharge. RESULTS: Compared to the UC group, the SAI scores at T2 and the AIS scores at T3 were lower in the CCBT group (p < 0.01 and p = 0.002). The positive rate of participants who were moderate and severe anxiety (SAI score > 37) at T2 were lower (72% vs. 88%, p = 0.04); the cortisol levels, SBP, DBP, and HR at T2 in the CCBT group were lower (p = 0.019 and all p < 0.01); the duration of anesthesia and PACU was shorter (p = 0.001 and p < 0.01); the CCBT group showed higher satisfaction scores. CONCLUSION: The newly developed cCBT program was an effective non-pharmacological adjunctive treatment for improving the surgery-related psychosomatic responses and perioperative outcomes. TRIAL REGISTRATION: The study was registered with the Chinese Clinical Trial Registry (ChiCTR1900025994) on 17 September 2019.
