Patient reported experience and adherence to remote patient management in chronic heart failure patients: a posthoc analysis of the TIM-HF2 trial.

AIMS: Remote patient management (RPM) enables early detection and prevention of deterioration in heart failure (HF) patients by measuring vital parameters. The analysis objective is to assess patient reported experience with RPM, adherence to daily measurements, and outline affecting factors both. METHODS AND RESULTS: Telemedical interventional management in-HF2 was conducted in 2013-18 with 1 538 HF patients with a 12-month follow-up. Under guidance of HF nurses, patients had to measure daily weight, blood pressure, electrocardiogram, and self-rated health status. At the end of the study, patients received a programme survey to analyse patient perceptions and satisfaction with telemedicine care and study organization. Adherence was distinguished between measurement of at least one [incomplete adherence (IA)] and all vital parameters [complete adherence (CA)] and defined as ratio of the number of days of measurements taken divided by the number of days of possible measurements. All data and group differences were analysed descriptively (mean ± SD) and by analysis of variance and t-test. Survey response rate was 79.7%. Patients were satisfied with the programme and device usability. CA was 89.1 ± 14.1%, consistently high over the study course and independent of severity of disease (left ventricular ejection fraction, N terminals pro brain natriuretic peptide, New York Heart Association). Lower IA was found with patients <70 years and prior to unplanned cardiovascular (CV) hospitalizations (difference by -5.2 ± 20.5%) and after unplanned CV hospitalizations compared with the entire study period (lower by -12.8 ± 24.7%). Patients from rural areas were found to have higher CA than patients from urban regions. CONCLUSIONS: With user-friendly devices, pre-interventional patient training, regular patient contact and close cooperation between primary physicians and telemedical centre, a long-lasting high adherence and satisfaction could be achieved. A change in adherence might detect health deterioration and indicate the need to intensify RPM.

Implementation of the ESC STEMI guidelines in female and elderly patients over a 20-year period in a large German registry.

AIMS: We investigated the implementation of new guidelines in ST-segment elevation myocardial infarction (STEMI) patients in a large real-world patient population in the metropolitan area of Berlin (Germany) over a 20-year period. METHODS: From January 2000 to December 2019, a total of 25 792 patients were admitted with STEMI to one of the 34 member hospitals of the Berlin-Brandenburg Myocardial Infarction Registry (B2HIR) and were stratified for sex and age < 75 and ≥ 75 years. RESULTS: The median age of women was 72 years (IQR 61-81) compared to 61 years in men (IQR 51-71). PCI treatment as a standard of care was implemented in men earlier than in women across all age groups. It took two years from the 2017 class IA ESC STEMI guideline recommendation to prefer the radial access route rather than femoral until > 60% of patients were treated accordingly. In 2019, less than 60% of elderly women were treated via a radial access. While the majority of patients < 75 years already received ticagrelor or prasugrel as antiplatelet agent in the year of the class IA ESC STEMI guideline recommendation in 2012, men ≥ 75 years lagged two years and women ≥ 75 three years behind. Amongst the elderly, in-hospital mortality was 22.6% (737) for women and 17.3% (523) for men (p < 0.001). In patients < 75 years fatal outcome was less likely with 7.2% (305) in women and 5.8% (833) in men (p < 0.001). After adjustment for confounding variables, female sex was an independent predictor of in-hospital mortality in patients ≥ 75 years (OR 1.37, 95% CI 1.12-1.68, p = 0.002), but not in patients < 75 years (p = 0.076). CONCLUSION: In-hospital mortality differs considerably by age and sex and remains highest in elderly patients and in particular in elderly females. In these patient groups, guideline recommended therapies were implemented with a significant delay.

Changes in treatment for NSTEMI in women and the elderly over the past 16 years in a large real-world population.

AIMS: This study investigates the changes in therapy for Non-ST-Elevation Myocardial Infarction (NSTEMI) over the past 16 years in a large German registry. In particular, the high-risk population of female and elderly patients was analyzed. METHODS: In total, 19.383 patients presenting with NSTEMI were included in this study. Patients were stratified by age groups <75 years and ≥75 years and by sex. Four different time periods from 2000-2004, 2005-2008, 2009-2012 and 2013-2016 were compared. Influence on hospital mortality as the primary outcome measure was assessed by logistic regression analysis. Secondary outcome measures included percutaneous coronary intervention (PCI), the use of drug eluting stents (DES), radial access route and major adverse cardiovascular events (MACE), defined as all-cause mortality, stroke, re-infarction, percutaneous re-intervention, intervention-related bleeding, cardiopulmonary resuscitation and new onset of cardiogenic shock or need for mechanical ventilation. RESULTS: Mortality decreased in all age groups between the initial time period and the most recent one (8.9% vs. 4.5%, p < 0.01), particularly in female patients ≥75 years (18.2% in 2000-2004 vs. 7.9% in 2013-2016, p < 0.01). Revascularization rates differed by gender (68.3% in women vs. 78.1% in men, p < 0.01) and by age (64.2% for ≥75 years vs. 80.9% for <75 years, p < 0.01). PCI rates in elderly female patients increased from 28.7% to 69.8% (p < 0.01) from the initial to the latest period. CONCLUSIONS: The present study demonstrates, that revascularization rates improved in all patient groups over the study period. However, females and elderly patients still remain less likely to be treated according to current guidelines.
