    • Background: Myocardial infarction (MI) occurs frequently and requires considerable health care resources. It is important to ensure that the treatments which are provided are both clinically effective and economically justifiable. Based on recent new evidence, routine oxygen therapy is no longer recommended in MI patients without hypoxemia. By using data from a nationwide randomized clinical trial, we estimated oxygen therapy related cost savings in this important clinical setting. Methods: The DETermination of the role of Oxygen in suspected Acute Myocardial Infarction (DETO2X-AMI) trial randomized 6,629 patients from 35 hospitals across Sweden to oxygen at 6 L/min for 6–12 h or ambient air. Costs for drug and medical supplies, and labor were calculated per patient, for the whole study population, and for the total annual care episodes for MI in Sweden (N = 16,100) with 10 million inhabitants. Results: Per patient, costs were estimated to 36 USD, summing up to a total cost of 119,832 USD for the whole study population allocated to oxygen treatment. Applied to the annual care episodes for MI in Sweden, costs sum up to between 514,060 and 604,777 USD. In the trial, 62 (2%) patients assigned to oxygen and 254 (8%) patients assigned to ambient air developed hypoxemia. A threshold analysis suggested that up to a cut-off of 624 USD spent for hypoxemia treatment related costs per patient, avoiding routine oxygen therapy remains cost saving. Conclusions: Avoiding routine oxygen therapy in patients with suspected or confirmed MI without hypoxemia at baseline saves significant expenditure for the health care system both with regards to medical and human resources.

  • Relations between implementation of new treatments and improved outcomes in patients with non-ST-elevation myocardial infarction during the last 20 years : experiences from SWEDEHEART registry 1995 to 2014
  • 2018
  • Ingår i: European Heart Journal. - : OXFORD UNIV PRESS. - 0195-668X .- 1522-9645. ; 39:42, s. 3766-3776

    • Aims We assessed the changes in short- and long-term outcomes and their relation to implementation of new evidence- based treatments in all patients with non-ST-elevation myocardial infarction (NSTEMI) in Sweden over 20 years. Methods and results Cases with NSTEMI (n = 205 693) between 1995 and 2014 were included from the nationwide Swedish Web-System for Enhancement and Development of Evidence-Based Care in Heart Disease Evaluated According to Recommended Therapies (SWEDEHEART) registry. During 20 years in-hospital invasive procedures increased from 1.9% to 73.2%, percutaneous coronary intervention or coronary artery bypass grafting 6.5% to 58.1%, dual antiplatelet medication 0% to 72.7%, statins 13.3% to 85.6%, and angiotensin-converting enzyme inhibitors/angiotensin II receptor blocker 36.8% to 75.5%. The standardized 1-year mortality ratio compared with a control population decreased from 5.53 [95% confidence interval (CI) 5.30-5.75] to 3.03 (95% CI 2.89-3.19). If patients admitted the first 2 years were modelled to receive the same invasive treatments as the last 2 years the expected mortality/ myocardial infarction (MI) rate would be reduced from 33.0% to 25.0%. After adjusting for differences in baseline characteristics, the change of 1-year cardiovascular death/MI corresponded to a linearly decreasing odds ratio trend of 0.930 (95% CI 0.926-0.935) per 2-year period. This trend was substantially attenuated [0.970 (95% CI 0.964-0.975)] after adjusting for changes in coronary interventions, and almost eliminated [0.988 (95% CI 0.982-0.994)] after also adjusting for changes in discharge medications. Conclusion In NSTEMI patients during the last 20 years, there has been a substantial improvement in long-term survival and re- duction in the risk of new cardiovascular events. These improvements seem mainly explained by the gradual uptake and widespread use of in-hospital coronary interventions and evidence-based long-term medications.
