Abstract:
This study aims to explore the application effects of the "3S2E" management model in standardized sputum specimen collection among patients without artificial airways, providing evidence for improving specimen quality and optimizing nursing workflows. A retrospective study was conducted on 100 hospitalized patients requiring sputum specimen collection from February 2024 to January 2025 in a hospital. Based on previous nursing models, patients were divided into a control group (routine nursing, n = 50) and a study group (3S2E management model, n = 50). The 2 groups were compared in terms of sputum specimen qualification rate, contamination rate, laboratory availability rate, and timeliness of submission. Patient cooperation, compliance, discomfort, satisfaction, and healthcare staff job satisfaction were assessed through questionnaires and nursing records. Typical cases were analyzed qualitatively. There were no statistically significant differences in baseline characteristics between the 2 groups (P > .05), ensuring comparability. The study group showed a significantly higher specimen qualification rate than the control group (90.0% vs 70.0%, P = .025), lower contamination rate (6.0% vs 20.0%, P = .043), higher laboratory availability rate (92.0% vs 72.0%, P = .010), and shorter submission time (1.2 ± 0.5 vs 1.8 ± 0.7 hours, P < .001). Patient cooperation and compliance were significantly improved in the study group (P < .05), while discomfort scores were significantly reduced (P < .001). In terms of satisfaction, patient satisfaction was higher in the study group than in the control group (90.0% vs 68.0%, P = .008), and healthcare staff job satisfaction was also markedly improved (8.3 ± 1.2 vs 7.1 ± 1.3, P < .001). There was no statistically significant difference in adverse event incidence between the groups (P = .14). Typical case analysis further indicated that the 3S2E model enhanced collection efficiency, reduced patient anxiety, and improved compliance. The 3S2E management model can effectively improve the standardization and qualification rate of sputum specimen collection in patients without artificial airways, reduce contamination, enhance patient experience and nursing satisfaction, and improve healthcare staff efficiency, showing strong value for clinical promotion and application.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
