Background: ONS is a cost-effective nutritional intervention whose effectiveness depends on sustained adherence, yet links among quality of discharge teaching, readiness for hospital discharge, medication beliefs, and adherence remain unclear. Methods: A convenience sample of 505 patients completed a cross-sectional survey (Jan 2023–Dec 2024) at a tertiary oncology hospital; analyses included descriptive statistics, Harman’s test, Pearson correlations, and mediation testing. Results: Variables were significantly interrelated; medication beliefs showed the strongest association with adherence, followed by readiness for discharge and discharge teaching.

However, the interrelationships among the quality of discharge teaching (QDT), readiness for hospital discharge (RHD), medication beliefs and adherence to ONS remain inadequately understood. Methods: A convenience sample of 505 postoperative patients with GC was recruited from January 1, 2023, to December 1, 2024, for a cross-sectional survey conducted at a tertiary-grade A specialised oncology hospital. The data of this study were subjected to descriptive analysis, Harman's one-way analysis of variance, Pearson correlation analysis and mediation effect analysis.  \nReporting Method: The STROBE checklist was employed for reporting in the study.  \nResults: Pearson correlation analyses revealed that all four variables were significantly interrelated. Structural equation modelling showed that medication beliefs had the strongest correlation with ONS adherence (β = 0.589), followed by readiness for hospital discharge (RHD) (β = 0.557) and quality of discharge teaching (QDT) (β = 0.523) . The structural equation model demonstrated a robust overall fit.  \nConclusion: There was a significant chain mediation effect through RHD and medication beliefs. For the development of targeted intervention strategies to improve ONS adherence, future research should prioritise enhancing QDT, optimising RHD and strengthening patients' medication beliefs.  \n\n| Abbreviations: BMQ, Beliefs about Medical Questionnaire; GC, gastric cancer; ONS, oral nutritional supplementation; ONSAS, Oral Nutritional Supplementation Adherence Scale; QDT, quality discharge teaching; QDTS, quality of Discharge Teaching Scale; RHD, readiness for Hospital Discharge; RHDS, readiness for Hospital Discharge Scale.\u003Cbr>Fang Shen, Xiaoxue Chen and Hong Yu are contributed equally to this manuscript. |\n| --- |\n| This is an open access article under the terms of the Creative Commons Attribution License, which permits use, distribution and reproduction in any medium, provided the original work is properly cited.\u003Cbr>© 2025 The Author(s).
