Abstract:
Objective: Coronary artery disease (CAD) remains the leading cause of morbidity and mortality
worldwide. Previous systematic reviews and meta-analysis of randomized controlled trials
concluded that nursing caring interventions (NCIs) are beneficial for coronary artery patients.
However, most of those interventions were conducted in outpatient or home-based settings or
through the telephone. Due to its multiple benefits, the authors recommended the application
of such interventions to hospitalized coronary artery patients. Currently, little is known on the
status of application of such evidence-based interventions in the actual clinical setting for
hospitalized coronary artery patients. Similar studies conducted in China were also inadequate.
Therefore, this study aimed to investigate the kinds of NCIs delivered to hospitalized coronary
artery patients and their consistent relationship with risk factors of CAD found in the clinical
records of patients. Results of this study were expected to alert nurses to consider such risk
factors when caring for coronary artery patients as well as appraising their caring efforts in
improving the patient’s wellbeing for the reduction of morbidity and mortality from a CAD
sequel. This report also disseminates some cardiovascular knowledge and health tips to the
readers.
Methods: A descriptive, cross-sectional, retrospective design using clinical case notes was
employed; the study was undertaken in coronary care wards at the teaching hospital in China
from November 2017 to September 2018. A total of 300 coronary artery case notes were
randomly selected from 700 eligible cardiovascular patients files by using a simple random
technique of simple random numbers through Microsoft office excel sheet. Chi-square (χ2) test
and multivariate logistic regression analysis for adjusted odds ratio with 95% confidence
interval (CI) within its range were used to compare the relationship among independent
(patient's demographic and clinical risk factors of CAD) and dependent variables (NCIs
implemented to such patients).
Results: A total of 300 coronary artery patients’ case notes were audited with a mean age of
63±11.2 years. Of these 175 (58.3%) were males, 126 (42%) were smokers and 224 (74.7%) were
hypertensive. NCIs such as “administer coronary artery medication and their instructions” was
mostly delivered to 291 (97%) patients. The delivery of three out of eight gathered NCIs were significantly influenced by three or all of these CAD risk factors (age, smoking, hypertension,
and diabetes) (p < 0.05 and/or < 0.01) with an adjusted odds ratio (95% CI) within their
significant ranges. Patients with diabetes mellitus were five times more likely to influence the
delivery of “administer medication and their instructions” than the rest of patients with
coronary artery risk factors (p < 0.01; AOR (95% CI) 5.02(2.059-7.207).
Conclusion: This study reveals that nurses delivered beneficial evidence-based interventions to
patients with CAD. The interventions were significantly consistent with age as an unmodifiable
risk factor and smoking, hypertension, and diabetes as modifiable risk factors of CAD. However,
the management of stress in these patients was low; and since stress may trigger CAD, it should
be assessed and managed appropriately.
