Objective: To determine differences in adherence to secondary prevention guidelines (pharmacological interventions) among coronary heart disease (CHD) patients between a Chinese medicine (CM) hospital and a general hospital in a Chinese city.
Methods: Medical records of 200 patients consecutively discharged from the CM hospital and the general hospital for CHD were reviewed to determine the proportions of eligible patients who received antiplatelet agents, β-blockers, angiotensin-converting enzyme (ACE) inhibitors or angiotensin receptor blockers (ARBs) and statins at discharge. The effects of patient characteristics and hospital type on the use of these medicines were estimated using logistic regression models.
Results: Patients discharged from the CM hospitals were older; more likely females; had greater history of hyperlipidemia, cerebrovascular diseases and less smoker (P<0.01 or P<0.05). They were less likely to receive coronary angiography and percutaneous coronary intervention, and had a longer length of stay than those discharged from the general hospital (P<0.01 or P<0.05). There were no significant differences in antiplatelet agents (96% vs. 100%, P=0.121) or statins (97.9% vs. 100%, P=0.149) use between the CM hospital and the general hospital. In multivariable analyses that adjusted for patient characteristics and hospital type, there was no significant difference in use of β-blockers between the CM hospital and the general hospital. In contrast, patients discharged from the CM hospital were less likely to receive ACE inhibitors/ARBs compared with those discharged from the general hospital (odds ratio: 0.3, 95% confidence interval: 0.105-0.854).
Conclusion: In this study, the CM hospital provides the same quality of care in CHD for prescribing evidence-based medications at discharge compared with another general hospital except for ACE inhibitors/ARBs use.
