Summary
Comparing German diagnosis-related groups (DRG) statistics and acute stroke treatment data, this study found no significant differences in ischemic stroke patient demographics or treatment rates. This supports adopting Hessian guidelines nationwide for better stroke data analysis.
Area of Science:
- Neurology
- Public Health
- Health Services Research
Background:
- Accurate data on acute ischemic stroke patient treatment is crucial for quality management.
- Methodological approaches for data collection can influence reported outcomes.
- German diagnosis-related groups (DRG) statistics and specific stroke registers offer different data sources.
Purpose of the Study:
- To compare the validity of German diagnosis-related groups (DRG) statistics against a dedicated stroke quality register for acute ischemic stroke patients.
- To assess the comparability of patient demographics and treatment rates between two distinct data sources.
- To evaluate the suitability of adopting specific data acquisition guidelines nationwide.
Main Methods:
- Comparative analysis of nationwide German diagnosis-related groups (DRG) statistics and the acute stroke treatment in Hesse (SA_HE) dataset for 2018.
- Inclusion of acute ischemic stroke patients (ICD code I63) treated in Hesse.
- Statistical comparison of patient demographics (gender, age) and treatment rates (systemic thrombolysis, mechanical thrombectomy).
Main Results:
- Both DRG statistics and SA_HE data captured comparable numbers of acute ischemic stroke patients (approx. 15,600-16,300).
- No statistically significant differences were found in gender distribution or age, except for a higher registration of older patients (>70 years) in DRG statistics.
- Rates for systemic thrombolysis (16.5%) and mechanical thrombectomy (approx. 5.8%) were highly consistent across both data sources.
Conclusions:
- The Hessian stroke quality register effectively captures acute ischemic stroke cases and treatment data.
- DRG statistics, with rational case limitation, provide comparable results to specialized stroke registers for key metrics.
- Adopting the Hessian guidelines for data acquisition and control nationwide could enable robust combined analyses of stroke data.
