Abstract:
A widespread problem among surgical patients, preoperative anxiety affects recovery, pain perception and general outcomes and calls for efficient remedies including quality control circle (QCC) approaches to enhance perioperative treatment. This study compared, among surgical patients, the efficacy of QCC treatments in lowering preoperative anxiety, boosting postoperative recovery and raising patient satisfaction against conventional treatment. A cross-sectional observational study was conducted on 180 patients in all who were scheduled for elective operations were allocated to either standard treatment (n = 90) or QCC interventions (n = 90). At admission, 1 day before surgery and 3 days following surgery, anxiety levels were measured with the state-trait anxiety inventory. The numeric rating scale and visual analog scale were used at 2, 12, 24, 48, and 72 hours to gauge postoperative pain. Recovery benchmarks, complications, and satisfaction levels were documented. Preoperatively (P = .005) and postoperatively (P = .003) patients in QCC treatments group had notably decreased anxiety scores. Recovering times were notably faster (P = .001: first drinking, 1.2 vs 3.5 days), first bowel movement (2.1 vs 3.2 days), and off-bed activity (3.0 vs 3.8 days). At all-time-points, the QCC group had regularly lower pain scores (P <.01). The QCC group had reduced complications (8.3% vs 15.6% P = .021) and greater satisfaction rates (89.4% vs 75.1%, P = .005). Ultimately, QCC treatments minimized the consequences by efficiently lowering anxiety, raising recovery benchmarks, improving pain management and raising patient satisfaction.
