How to measure quality of care in patients presenting with STEMI? A single-centre experience
Insights
Assessing acute coronary syndrome care quality requires more than basic indicators. A study found that proposed quality metrics for ST-elevated myocardial infarction (STEMI) patients were insufficient for hospital comparison, highlighting the need for risk-adjusted mortality analysis.
Area of Science:
- Cardiology
- Healthcare Quality Improvement
Background:
- Evaluating healthcare quality for acute coronary syndromes (ACS) is crucial.
- New regulations in Belgium prompted a project to assess STEMI care using four quality indicators.
- Concerns were raised about the sufficiency of these indicators for comprehensive quality assessment.
Purpose of the Study:
- To retrospectively analyze a broader set of parameters for quality of care in STEMI patients.
- To evaluate the applicability of these parameters as indicators of healthcare quality.
- To determine if the initially proposed quality indicators were adequate for hospital comparison.
Main Methods:
- A retrospective analysis of 38 indicators was conducted.
- Data from 153 STEMI patients treated with percutaneous coronary intervention (PCI) at UZ Brussels in 2013 were analyzed.
- Patients included both on-site admissions and transfers.
Main Results:
- Overall unadjusted mortality was 7.2%.
- Significant differences in unadjusted mortality were noted between on-site (10.7%) and transferred (2.9%) patients, influenced by initial condition and cardiogenic shock.
- Discharge medication adherence aligned well with European Society of Cardiology (ESC) guidelines.
Conclusions:
- The study concludes that the four proposed quality indicators are insufficient for comparing hospital performance.
- It emphasizes the critical importance of risk-adjusting mortality data for accurate hospital comparison.
- A more comprehensive set of indicators is needed to truly reflect the quality of care for STEMI patients.
Objective:
The evaluation of the quality of care delivered to patients with acute coronary syndromes is becoming increasingly important. Due to novel regulations permitting the installation of new catheterization laboratories in Belgium, the Flemish government initiated a project to measure quality of care in patients with an ST-elevated myocardial infarction (STEMI) by measuring four quality indicators: prescription of ACE inhibitor, beta blocker or aspirin on discharge and unadjusted mortality. However, we are not convinced that these four indicators will provide sufficient information on the quality of care in our hospitals. Hence, we performed a retrospective analysis on a larger set of parameters and evaluated their applicability as indicators of quality of care.
Methods:
We measured 38 indicators in 153 patients (69 transferred and 84 on-site) with a STEMI who presented at, or were transferred to the UZ Brussels in 2013 and received percutaneous coronary intervention (PCI).
Results:
The unadjusted overall mortality was 7.2% (n = 11/153). Important differences in unadjusted mortality were observed between the on-site and transferred patients (10.7%, n = 9 vs 2.9%, n = 2, P = 0.112), which were attributed to the initial condition at presentation and a larger proportion of cardiogenic shocks in the on-site group. Discharge medication highly corresponded with the ESC guidelines.
Conclusion:
We demonstrate that the proposed quality indicators do not provide sufficient information to compare hospitals and that it is of utmost importance to weigh the mortality according to risk profile.
