Purpose
This study investigated the influence of disease-related knowledge and health empowerment on health behavior compliance among patients who underwent percutaneous coronary intervention.
Methods
This descriptive correlational study involved 155 patients who underwent coronary intervention at a tertiary hospital. Data were collected using structured questionnaires measuring health behavior compliance, disease-related knowledge, and health empowerment from May to August 2024. Data were analyzed with descriptive statistics, the independent t-test, one-way analysis of variance, Pearson correlation coefficients, and multiple regression analysis using SPSS ver. 27.0.
Results
Participants showed mean scores of 0.67±0.20 (out of 1) for disease-related knowledge, 3.25±0.99 (out of 5) for health empowerment, and 1.76±0.52 (out of 3) for health behavior compliance. Educational level (t=–5.05, P<0.001) and monthly income (F=11.90, P<0.001) showed significant differences according to health behavior compliance. Multiple regression analysis revealed that health empowerment (β=0.69, P<0.001) and disease-related knowledge (β=0.17, P=0.006) were significant predictors of health behavior compliance, explaining 65% of variance (F=57.50, P<0.001).
Conclusion
These findings demonstrate that health empowerment and disease-related knowledge significantly affect health behavior compliance in post–coronary intervention patients. Healthcare providers should implement comprehensive interventions aimed at enhancing these factors to improve patient outcomes.

Purpose
Attending physicians in Korea are aware of the existence of the Nutrition Support Team (NST), but even when the NST are consulted, compliance with their recommendations may be low. This study was performed to identify physicians’ compliance with the NST advice and how this affected the outcome of treatment for critically ill patients.
Methods
This study was a retrospective observational study. Critically ill patients who were older than 18 years, younger than 90 years, and had been admitted and managed in the intensive care unit were selected for this study. Patients were assigned to either the compliance group or the non-compliance group according to physician compliance with the NST advice. Each group were compared using variables such as calorie supply, protein supply, laboratory findings, hospital stay, 30-day mortality, and survival rate.
Results
The compliance group (81% of cases) was supplied with a significantly higher energy (1,146.36 ± 473.45 kcal vs. 832.45 ± 364.28 kcal, p < 0.01) and a significantly higher protein (55.00 ± 22.30 g/day vs. 42.98 ± 24.46 g/day, p = 0.04) compared with the non-compliance group. There was no significant difference in the basic demographics between groups, although the compliance group had a better outcome in the 30-day mortality rate (8% vs. 26%, p = 0.02), and in survival beyond 1 year (Crude model, hazard ratio: 2.42, CI: 1.11-5.29).
Conclusion
Critically ill patients whose attending physician complied with the NST advice, received an increased energy intake and supply of protein which was positively associated with survival.
