Analysis of Association between Acute Myocardial Infarction Treatment Costs and Outcomes

Description

To analyze trends in association between AMI patient treatment costs and achieved outcomes in Latvian hospitals. . Administrative data for 9795 hospitalizations with diagnose acute myocardial infarction (hospital discharge diagnose) in 2019 – 2021, data on 30-day mortality, data on patients individual demographic characteristics (age, sex, co-morbidities (quantified by Charlson index), treatment costs, applied invasive manipulations were used to estimate association between treatment cost and achieved outcome. Binary logistic regression model was constructed to estimate impact of every factor and its’ statistical significance.. Total number of hospitalizations with AMI diagnose has decreased over the period of analysis from 3590 in 2019 till 2885 in 2021. The average cost of treatment per patient is increasing from 2571,91 ((95% CI: 2497,75-2646,07) in 2019 till 3167,01 ((95% CI: 23073,78-3260,24) in 2021. Cost of treatment for patients received PCI is substantially higher 4360,93 EUR (95% CI: 4312,28-4409,58), than for patients received thrombolytic therapy 644,68 EUR (95% CI: 619,38-669,98). Patients received PCI have lower age 67,38 (95% CI: 65,64-69,13) than those received therapy 72,68 (95% CI: 72,28-73,08). Average level of comorbidities, assessed by Charlson index is also lower for patients received PCI: 0,94 (95% CI: 0,92-0,98) and 1,20 (95% CI: 1,16-1,24) correspondingly. Within both groups of patients association between patient’s outcome (assessed with 30- days mortality) and cost of treatment is not statistically significant after controlling for age and comorbidities (p>0,5). . The study did not reveal associations between patient level cost of treatment and patient outcome (30 day mortality), after controlling for patient’s demographic characteristics (age, sex) and level of comorbidities for patients, hospitalized with AMI between in 2019 – 2021 in Latvian hospitals. Additional researches are needed to discover main drivers of treatment costs.
