The cost of CIED infectious complications treatment in Poland from the perspective of Polish hospitals.

INTRODUCTION: Cardiac implantable electronic devices (CIED) are a recognized form of therapy in cardiology. Apart from the benefits, the use of CIEDs is also associated with the risk of complications, and the most important ones influencing treatment results and prognosis are infectious complications. AIM: This study aimed to calculate the cost of treatment of CIED-related infections, including transvenous lead extraction and device reimplantation, from the perspective of a Polish hospital. METHODS: A retrospective analysis of hospitalization costs of patients referred to transvenous lead extraction (TLE) for CIED infection was performed. The study covers cases from three Polish reference centers specializing in the comprehensive treatment of cardiac electrotherapy complications. RESULTS: It was shown that the average cost of treating a CIED infection is 34 000 PLN (8010 EUR) and is the highest in the cardiac resynchronization therapy with defibrillator function (CRT-D) group, where it amounts to almost 50 000 PLN (11 440 EUR). Thus, treatment of CIED infections is associated with an average loss of 3000 PLN for the healthcare provider and the length of hospitalization has a major influence on final outcomes. CONCLUSIONS: The hospital cost of treatment of CIED-related infections was high and related mainly to the type of device and length of hospitalization. Despite the low utilization of costly extraction tools, the hospitalization was still likely to be unprofitable.

Managed Care after Acute Myocardial Infarction (MC-AMI) improves prognosis in AMI survivors with pre-existing heart failure: A propensity score matching analysis of Polish nationwide program of comprehensive post-MI care.

BACKGROUND: Despite improvement in acute myocardial infarction (AMI) treatment, post-discharge mortality remains high. The outcomes are supposed to be even worse in patients with post-MI heart failure (HF), as only a half of patients with newly diagnosed HF survive four years. AIMS: The study aimed to analyze whether managed care after acute myocardial infarction (MC-AMI) is associated with better survival in AMI survivors with a pre-existing diagnosis of HF. RESULTS: The study included 7228 patients with a pre-existing diagnosis of HF who survived the hospitalization for AMI in Poland between November 2017 and December 2020, of whom 2268 (31.4%) were referred for the MC-AMI program. The median follow-up was 1.5 (0.7-2.3) years. In the unmatched analysis, patients without MC-AMI had more than twice higher 12-month mortality (21.8% vs. 9.9%; P <0.01) than MC-AMI participants. The difference remained significant after propensity score matching (16,8% vs. 10.0%; P <0.01). In multivariable analysis, participation in MC-AMI was an independent factor of 12-month survival. MC-AMI participants had a lower stroke rate (1.5% vs. 3.0%; P <0.01) and fewer hospital admissions due to HF (22.9% vs. 27.6%; P <0.01). CONCLUSIONS: After propensity score matching, participation in MC-AMI was associated with lower rates of stroke, HF hospitalizations, and all-cause mortality in the 12-month follow-up and was an independent factor of 12-month survival in AMI survivors with pre-existing HF.

Burden of medical co-morbidities and benefit from surgical revascularization in patients with ischaemic cardiomyopathy.

AIMS: The landmark STICH trial found that surgical revascularization compared to medical therapy alone improved survival in patients with heart failure (HF) of ischaemic aetiology and an ejection fraction (EF) ≤ 35%. However, the interaction between the burden of medical co-morbidities and the benefit from surgical revascularization has not been previously described in patients with ischaemic cardiomyopathy. METHODS AND RESULTS: The STICH trial (ClinicalTrials.gov Identifier: NCT00023595) enrolled patients ≥ 18 years of age with coronary artery disease amenable to coronary artery bypass grafting (CABG) and an EF ≤ 35%. Eligible participants were randomly assigned 1:1 to receive medical therapy (MED) (n = 602) or MED/CABG (n = 610). A modified Charlson co-morbidity index (CCI) based on the availability of data and study definitions was calculated by summing the weighted points for all co-morbid conditions. Patients were divided into mild/moderate (CCI 1-4) and severe (CCI ≥ 5) co-morbidity. Cox proportional hazards models were used to evaluate the association between CCI and outcomes and the interaction between severity of co-morbidity and treatment effect. The study population included 349 patients (29%) with a mild/moderate CCI score and 863 patients (71%) with a severe CCI score. Patients with a severe CCI score had greater functional limitations based on 6-min walk test and impairments in health-related quality of life as assessed by the Kansas City Cardiomyopathy Questionnaire. A total of 161 patients (Kaplan-Meier rate = 50%) with a mild/moderate CCI score and 579 patients (Kaplan-Meier rate = 69%) with a severe CCI score died over a median follow-up of 9.8 years. After adjusting for baseline confounders, patients with a severe CCI score were at higher risk for all-cause mortality (hazard ratio 1.44, 95% confidence interval 1.19-1.74; P < 0.001). There was no interaction between CCI score and treatment effect on survival (P = 0.756). CONCLUSIONS: More than 70% of patients had a severe burden of medical co-morbidities at baseline, which was independently associated with increased risk of death. There was not a differential benefit of surgical revascularization with respect to survival based on severity of co-morbidity.
