Calculation based on OECD methodology.

ADMISSION BASED AMI 30 DAY IN-HOSPITAL (SAME HOSPITAL) MORTALITY =  number of deaths in the same hospital that occurred within 30 days of the admission date of the AMI admission cases (I21-I22 according ICD-10)/number of admissions to hospital for acute non-elective (urgent) care with a primary diagnosis of acute myocardial infarction (AMI) (I21-I22 according ICD-10)*100

PATIENT BASED AMI 30 DAY (IN-HOSPITAL AND OUT OF HOSPITAL) MORTALITY =  number of deaths in and out the hospital that occurred within 30 days of the admission date of the AMI admission cases (I21-I22 according ICD-10)/number of last admission to hospital for acute non-elective (urgent) care with a primary diagnosis of acute myocardial infarction (AMI) (I21-I22 according ICD-10)*100

ADMISSION BASED ISCHEMIC STROKE 30 DAY IN-HOSPITAL (SAME HOSPITAL) MORTALITY =  number of deaths in the same hospital that occurred within 30 days of the admission date of the ischemic stroke admission cases (I63-I64 according ICD-10)/number of admissions to hospital for acute non-elective (urgent) care with a primary diagnosis of ischemic stroke (I63-I64 according ICD-10)*100

PATIENT BASED ISCHEMIC STROKE 30 DAY (IN-HOSPITAL AND OUT OF HOSPITAL) MORTALITY =  number of deaths in and out the hospital that occurred within 30 days of the admission date of the ischemic stroke admission cases (I63-I64 according ICD-10)/number of last admission to hospital for acute non-elective (urgent) care with a primary diagnosis of ischemic stroke (I63-I64 according ICD-10)*100

ADMISSION BASED HEMORRHAGIC STROKE 30 DAY IN-HOSPITAL (SAME HOSPITAL) MORTALITY =  number of deaths in the same hospital that occurred within 30 days of the admission date of the hemorrhagic stroke admission cases (I60-I62 according ICD-10)/number of admissions to hospital for acute non-elective (urgent) care with a primary diagnosis of hemorrhagic stroke (I60-I62according ICD-10)*100

PATIENT BASED HEMORRHAGIC STROKE 30 DAY (IN-HOSPITAL AND OUT OF HOSPITAL) MORTALITY =  number of deaths in and out the hospital that occurred within 30 days of the admission date of the hemorrhagic stroke admission cases (I60-I62 according ICD-10)/number of last admission to hospital for acute non-elective (urgent) care with a primary diagnosis of hemorrhagic stroke (I60-I62 according ICD-10)*100
