Researchers say the Patient Safety Indicator 04 (PSI 04) misclassifies unavoidable stroke complications as safety issues, penalizing hospitals.
The study suggests these flaws can make hospitals seem to have poor safety records despite high-quality care.
The analysis covered more than 73,500 thrombectomy patients, and about 21% were flagged by PSI 04, higher than other indicators.
