Cost-effectiveness of noninvasive telemedical interventional management in patients with heart failure: health economic analysis of the TIM-HF2 trial.

ABSTRACT:

Background

Noninvasive remote patient management (RPM) in patients with heart failure (HF) has been shown to reduce the days lost due to unplanned cardiovascular hospital admissions and all-cause mortality in the Telemedical Interventional Management in Heart Failure II trial (TIM-HF2). The health economic implications of these findings are the focus of the present analyses from the payer perspective.

Methods and results

A total of 1538 participants of the TIM-HF2 randomized controlled trial were assigned to the RPM and Usual Care group. Health claims data were available for 1450 patients (n = 715 RPM group, n = 735 Usual Care group), which represents 94.3% of the original TIM-HF2 patient population, were linked to primary data from the study documentation and evaluated in terms of the health care cost, total cost (accounting for intervention costs), costs per day alive and out of hospital (DAOH), and cost per quality-adjusted life year (QALY). The average health care costs per patient year amounted to € 14,412 (95% CI 13,284-15,539) in the RPM group and € 17,537 (95% CI 16,179-18,894) in the UC group. RPM led to cost savings of € 3125 per patient year (p = 0.001). After including the intervention costs, a cost saving of € 1758 per patient year remained (p = 0.048).

Conclusion

The additional noninvasive telemedical interventional management in patients with HF was cost-effective compared to standard care alone, since such intervention was associated with overall cost savings and superior clinical effectiveness.

Project description:AimsPatients with chronic heart failure (CHF) have an increased risk of ischaemic stroke. We aimed to identify the incidence rate and factors associated with ischaemic stroke or transient ischaemic attack (TIA) in CHF patients as well as the impact of non-invasive telemedical care (NITC) on acute stroke/TIA.Methods and resultsWe retrospectively analysed baseline characteristics of 2248 CHF patients enrolled to the prospective multicentre Telemedical Interventional Monitoring in Heart Failure study (TIM-HF) and Telemedical Interventional Management in Heart Failure II study (TIM-HF2), randomizing New York Heart Association (NYHA) II/III patients 1:1 to NITC or standard of care. Hospitalizations due to acute ischaemic stroke or TIA during a follow-up of 12 months were analysed. Old age, hyperlipidaemia, lower body mass index, and peripheral arterial occlusive disease (PAOD) were independently associated with present cerebrovascular disease on enrolment. The stroke/TIA rate was 1.5 per 100 patients-years within 12 months after randomization (n = 32, 1.4%). Rate of stroke/TIA within 12 months was in the intervention group similar compared with the control group (50.0% vs. 49.8%; P = 0.98) despite that the rate of newly detected atrial fibrillation (AF) was higher in the intervention group (14.1% vs. 1.6%; P < 0.001). A history of PAOD (OR 2.7, 95% CI 1.2-6.2; P = 0.02) and the highest tertile (OR 3.0, 95% CI 1.1-8.3) of N-terminal pro-brain natriuretic peptide (NT-proBNP) on enrolment were associated with stroke/TIA during follow-up. In patients who suffered acute stroke or TIA during follow-up, echocardiography was part of the diagnostic workup in only 56% after hospital admission.ConclusionsAnnual rate of ischaemic stroke/TIA in NYHA II/III patients is low but higher in those with elevated NT-proBNP levels and history of PAOD at baseline. NITC showed no impact on the stroke rate during 1 year follow-up despite a significantly higher rate of newly detected AF. Irrespective of known CHF, echocardiography was often missing during in-hospital diagnostic workup after acute stroke/TIA.

Project description:AimsTelemedical emergency services for heart failure (HF) patients are usually provided during business hours. However, many emergencies occur outside of business hours. This study evaluates if a 24/7 telemedical emergency service is needed for the remote management of high-risk HF patients.Methods and resultsThe study included 1119 patients merged from the TIM-HF and TIM-HF2 trials [age 69 ± 11, 73% male, left ventricular ejection fraction 37% ± 13, 557 New York Heart Association (NYHA) II/562 NYHA III]. Patients received a 24/7 physician-guided emergency service provided by the telemedical centre (TMC) in addition to remote management within business hours. During emergency calls, patient status, symptoms, electronic patient record, and instant telemonitoring data were evaluated by the TMC physician. Following diagnosis, patients were referred for hospital admission or instructed to stay at home. Apart from the TMC, patients could place a call to the public emergency service at any time. Seven hundred sixty-eight emergency calls were placed over 1383 patient years (0.56 calls/patient year). Five hundred twenty-six calls (69%) occurred outside business hours. There were 146 (19%) emergency calls for worsening HF, 297 (39%) other cardiovascular, and 325 (42%) non-cardiac causes, with a similar pattern inside and outside business hours. Of the 1119 patients, 417 (37%) placed at least one emergency call. Patients with NYHA Class III, higher N-terminal prohormone of brain natriuretic peptide (>1.400 pg/mL) levels, ischaemic aetiology of HF, implanted defibrillator, and impaired renal function had a higher probability of placing emergency calls. During study follow-up, patients who made an emergency call had a higher all-cause mortality (22% vs. 11%, P = 0.007 in TIM-HF; 16% vs. 4%, P < 0.001 in TIM-HF2) and more unplanned hospitalizations (324 vs. 162, P < 0.001 in TIM-HF; 545 vs. 180, P < 0.001 in TIM-HF2). Of the total 1,211 unplanned hospital admissions, 492 (41%) were initiated by a patient emergency call. Three hundred seventy-nine calls (49%) were placed to the TMC, whereas 389 calls (51%) were made to the public emergency service. Three hundred twenty-six (84%) of the calls to the public emergency service resulted in acute hospitalizations. The TMC initiated 202 (53%) hospital admissions; 177 (47%) patients were advised to stay at home. All patients that remained at home were alive during a prespecified safety period of 7 days post-call. Diagnoses made by the TMC physician were confirmed in 83% of cases by the hospital.ConclusionA telemedical emergency service for high-risk HF patients is safe and should operate 24/7 to reduce unplanned hospitalizations. Emergency calls could be considered as a marker for higher morbidity and mortality.

Project description:In a rapidly growing and aging population, heart failure (HF) has become recognised as a public health concern that imposes high economic and societal costs worldwide. HF management stems from the use of highly cost-effective angiotensin converting enzyme inhibitors (ACEi) and β-blockers to the use of newer drugs such as sodium-glucose cotransporter-2 inhibitors (SGLT2i), ivabradine, and vericiguat. Modelling studies of pharmacological treatments that report on cost effectiveness in HF is important in order to guide clinical decision making. Multiple cost-effectiveness analysis of dapagliflozin for heart failure with reduced ejection fraction (HFrEF) suggests that it is not only cost-effective and has the potential to improve long-term clinical outcomes, but is also likely to meet conventional cost-effectiveness thresholds in many countries. Similar promising results have also been shown for vericiguat while a cost effectiveness analysis (CEA) of empagliflozin has shown cost effectiveness in HF patients with Type 2 diabetes. Despite the recent FDA approval of dapagliflozin and empagliflozin in HF, it might take time for these SGLT2i to be widely used in real-world practice. A recent economic evaluation of vericiguat found it to be cost effective at a higher cost per QALY threshold than SGLT2i. However, there is a lack of clinical or real-world data regarding whether vericiguat would be prescribed on top of newer treatments or in lieu of them. Sacubitril/valsartan has been commonly compared to enalapril in cost effectiveness analysis and has been found to be similar to that of SGLT2i but was not considered a cost-effective treatment for heart failure with reduced ejection fraction in Thailand and Singapore with the current economic evaluation evidences. In order for more precise analysis on cost effectiveness analysis, it is necessary to take into account the income level of various countries as it is certainly easier to allocate more financial resources for the intervention, with greater effectiveness, in high- and middle-income countries than in low-income countries. This review aims to evaluate evidence and cost effectiveness studies in more recent HF drugs i.e., SGLT2i, ARNi, ivabradine, vericiguat and omecamtiv, and gaps in current literature on pharmacoeconomic studies in HF.
