Effects of Home-Based White Noise Therapy Combined with Positive Reinforcement-Based Nursing on Sleep Quality and Negative Emotions in Patients After Painless Endoscopic Gastrointestinal Polypectomy.

OBJECTIVE

To explore the efficacy of home-based white noise therapy combined with positive reinforcement-based nursing on sleep quality, negative emotions, hope level, and postoperative complications in patients after painless endoscopic gastrointestinal polypectomy.

METHODS

A retrospective cohort study was conducted on 130 patients who underwent painless endoscopic gastrointestinal polypectomy at Nantong First People's Hospital between November 2023 and November 2024. Patients were categorized into a combination group ( n  = 65, routine care, home-based white noise therapy, and positive reinforcement-based nursing) and a routine group ( n  = 65, routine home care) based on the nursing regimen they received. Pittsburgh Sleep Quality Index (PSQI), Self-Rating Anxiety Scale (SAS), Self-Rating Depression Scale (SDS), Herth Hope Index (HHI) scores, and postoperative complication rates were compared between the two groups after nursing.

RESULTS

After care, the combination group had significantly lower PSQI, SAS, and SDS scores (all P < 0.05) and significantly higher HHI scores in all dimensions and total score than the routine group (all P < 0.05). The total complication rate was numerically lower in the combination group than in the routine group (1.54% versus 10.76%), but the difference was not statistically significant (Fisher's exact test, P  = 0.062).

CONCLUSION

Home-based white noise therapy combined with positive reinforcement-based nursing was associated with improved sleep quality, reduced negative emotions, increased hope level, and lower postoperative complication rates in patients after painless endoscopic gastrointestinal polypectomy, suggesting its potential value for clinical application.
