Mortality, outcomes, costs, and use of medicines following a first heart failure hospitalization: EVOLUTION HF
Background:
There are few contemporary data on outcomes, costs, and treatment following a hospitalization for heart failure (hHF) in epidemiologically representative cohorts.
Objectives:
The study sought to describe rehospitalizations, hospitalization costs, use of guideline-directed medical therapy (GDMT) (renin-angiotensin system inhibitors, sacubitril/valsartan, beta-blockers, mineralocorticoid receptor antagonists, and sodium-glucose cotransporter-2 inhibitors), and mortality after hHF.
Methods:
EVOLUTION HF (Utilization of Dapagliflozin and Other Guideline Directed Medical Therapies in Heart Failure Patients: A Multinational Observational Study Based on Secondary Data) is an observational, longitudinal cohort study using data from electronic health records or claims data sources in Japan, Sweden, the United Kingdom, and the United States. Adults with a first hHF discharge between 2018 and 2022 were included. One-year event rates per 100 patient-years (ERs) for death and rehospitalizations (with a primary diagnosis of heart failure (HF), chronic kidney disease [CKD], myocardial infarction, stroke, or peripheral artery disease) were calculated. Hospital health care costs were cumulatively summarized. Cumulative GDMT use was assessed using Kaplan-Meier estimates.
Results:
Of 263,525 patients, 28% died within the first year post-hHF (ER: 28.4 [95% CI: 27.0-29.9]). Rehospitalizations were mainly driven by HF (ER: 13.6 [95% CI: 9.8-17.4]) and CKD (ER: 4.5 [95% CI: 3.6-5.3]), whereas the ERs for myocardial infarction, stroke, and peripheral artery disease were lower. Health care costs were predominantly driven by HF and CKD. Between 2020 and 2022, use of renin-angiotensin system inhibitors, sacubitril/valsartan, beta-blockers, and mineralocorticoid receptor antagonists changed little, whereas uptake of sodium-glucose cotransporter-2 inhibitors increased 2- to 7-fold.
Conclusions:
Incident post-hHF rehospitalization risks and costs were high, and GDMT use changed little in the year following discharge, highlighting the need to consider earlier and greater implementation of GDMT to manage risks and reduce costs
Lower Risk of Heart Failure and Death in Patients Initiated on Sodium-Glucose Cotransporter-2 Inhibitors Versus Other Glucose-Lowering DrugsClinical Perspective: The CVD-REAL Study (Comparative Effectiveness of Cardiovascular Outcomes in New Users of Sodium-Glucose Cotransporter-2 Inhibitors)
Reduction in cardiovascular death and hospitalization for heart failure (HHF) was recently reported with the sodium-glucose cotransporter-2 inhibitor (SGLT-2i) empagliflozin in patients with type 2 diabetes mellitus who have atherosclerotic cardiovascular disease. We compared HHF and death in patients newly initiated on any SGLT-2i versus other glucose-lowering drugs in 6 countries to determine if these benefits are seen in real-world practice and across SGLT-2i class
Healthcare utilization and costs following newly diagnosed type-2 diabetes in Sweden: A follow-up of 38,956 patients in a clinical practice setting.
To describe healthcare resource use patterns and estimate healthcare costs of newly diagnosed Type 2 diabetes mellitus (T2DM) patients in Sweden
Increased healthcare utilization costs following initiation of insulin treatment in type 2 diabetes: A long-term follow-up in clinical practice
Aims: To compare long-term changes in healthcare utilization and costs for type 2 diabetes patients before and after insulin initiation, as well as healthcare costs after insulin versus non-insulin anti-diabetic (NIAD) initiation. Methods: Patients newly initiated on insulin (n = 2823) were identified in primary health care records from 84 Swedish primary care centers, between 1999 to 2009. First, healthcare costs per patient were evaluated for primary care, hospitalizations and secondary outpatient care, before and up to seven years after insulin initiation. Second, patients prescribed insulin in second line were matched to patients prescribed NIAD in second line, and the healthcare costs of the matched groups were compared. Results: The total mean annual healthcare cost increased from 1656 per patient 2 years before insulin initiation to 3814 seven years after insulin initiation. The total cumulative mean healthcare cost per patient at year 5 after second-line treatment was 13,823 in the insulin group compared to 9989 in the NIAD group. Conclusions: Initiation of insulin in type 2 diabetes patients was followed by increased healthcare costs. The increases in costs were larger than those seen in a matched patient population initiated on NIAD treatment in second-line. (C) 2016 The Author(s).

Blood pressure levels and risk of cardiovascular events and mortality in type-2 diabetes: cohort study of 34 009 primary care patients.
OBJECTIVE:: The optimal blood pressure (BP) in persons with type-2 diabetes is debated. We investigated shapes of the associations of SBP and DBP levels with risk of cardiovascular events and mortality in a large primary care-based sample of diabetic patients. METHODS:: We investigated all 34 009 consecutive cardiovascular disease-free type-2 diabetes patients aged 35 years or older (mean age 64 years) at 84 primary care centers in central Sweden between 1999 and 2008. We followed this cohort until the end of 2009 in national registries for the incidence of major cardiovascular events (a composite endpoint of myocardial infarction, stroke, heart failure, or cardiovascular mortality) or total mortality. RESULTS:: During up to 11 years of follow-up, 6344 patients (18.7%) had a first cardiovascular event, and 6235 died (18.3%). The associations of annually updated SBP and DBP with risk of major cardiovascular events were U-shaped. The lowest risk of cardiovascular events was observed at a SBP of 135-139 mmHg and a DBP of 74-76 mmHg, and the lowest mortality risk at a SBP of 142-150 mmHg and a DBP of 78-79 mmHg, in both antihypertensive drug-untreated and drug-treated persons. CONCLUSION:: In a large primary care-based sample of patients with type-2 diabetes, associations of SBP and DBP with risk of major cardiovascular events and mortality were U-shaped. This may have implications for risk stratification of persons with diabetes
Are there lost opportunities in chronic kidney disease? A region-wide cohort study
OBJECTIVES: Identify the windows of opportunity for the diagnosis of chronic kidney disease (CKD) and the prevention of its adverse outcomes and quantify the potential population gains of such prevention. DESIGN AND SETTING: Observational, population-wide study of residents in the Stockholm and Skåne regions of Sweden between 1 January 2015 and 31 December 2020. PARTICIPANTS: All patients who did not yet have a diagnosis of CKD in healthcare but had CKD according to laboratory measurements of CKD biomarkers available in electronic health records. OUTCOME MEASURES: We assessed the proportions of the patient population that received a subsequent diagnosis of CKD in healthcare, that used guideline-directed pharmacological therapy (statins, renin-angiotensin aldosterone system inhibitors (RAASi) and/or sodium-glucose cotransporter-2 inhibitors (SGLT2i)) and that experienced adverse outcomes (all-cause mortality, cardiovascular mortality or major adverse cardiovascular events (MACE)). The potential to prevent adverse outcomes in CKD was assessed using simulations of guideline-directed pharmacological therapy in untreated subsets of the study population. RESULTS: We identified 99 382 patients with undiagnosed CKD during the study period. Only 33% of those received a subsequent diagnosis of CKD in healthcare after 5 years. The proportion that used statins or RAASi was of similar size to the proportion that didn't, regardless of how advanced their CKD was. The use of SGLT2i was negligible. In simulations of optimal treatment, 22% of the 21 870 deaths, 27% of the 14 310 cardiovascular deaths and 39% of the 22 224 MACE could have been avoided if every patient who did not use an indicated medication for their laboratory-confirmed CKD was treated with guideline-directed pharmacological therapy for CKD. CONCLUSIONS: While we noted underdiagnosis and undertreatment of CKD in this large contemporary population, we also identified a substantial realisable potential to improve CKD outcomes and reduce its burden by treating patients early with guideline-directed pharmacological therapy
Dapagliflozin and cardiovascular mortality and disease outcomes in a population with type 2 diabetes similar to that of the DECLARE-TIMI 58 trial : A nationwide observational study
Aims: To investigate cardiovascular (CV) safety and event rates for dapagliflozin versus other glucose-lowering drugs (GLDs) in a real-world type 2 diabetes population after applying the main inclusion criteria and outcomes from the DECLARE-TIMI 58 study. Methods: Patients with new initiation of dapagliflozin and/or other GLDs were identified in Swedish nationwide healthcare registries for the period 2013 to 2016. Patients were included if they met the main DECLARE-TIMI 58 inclusion criteria: age 40years and established CV disease or presence of multiple-risk factors, e.g. men aged 55years and women aged 60years with hypertension or dyslipidaemia. Propensity scores for the likelihood of dapagliflozin initiation were calculated, then 1:3 matching was carried out. DECLARE-TIMI 58 outcomes were hospitalization for heart failure (HHF) or CV-specific mortality, and major adverse CV events (MACE; CV-specific mortality, myocardial infarction, or stroke). Cox survival models were used to estimate hazard ratios (HRs). Results: After matching, a total of 28408 new-users of dapagliflozin and/or other GLDs were identified, forming the population for the present study (henceforth referred to as the DECLARE-like cohort. The mean age of this cohort was 66years, and 34% had established CV disease. Dapagliflozin was associated with 21% lower risk of HHF or CV mortality versus other GLDs (HR 0.79, 95% confidence interval [CI] 0.69-0.92) and had no significant association with MACE (HR 0.90, 95% CI 0.79-1.03). HHF and CV mortality risks, separately, were lower at HR 0.79 (95% CI 0.67-0.93) and HR 0.75 (95% CI 0.57-0.97), respectively. Non-significant associations were seen for myocardial infarction and stroke: HR 0.91 (95% CI 0.74-1.11) and HR 1.06 (95% CI 0.87-1.30), respectively. Conclusion: In a real-world population similar to those included in the DECLARE-TIMI 58 study, dapagliflozin was safe with regard to CV outcomes and resulted in lower event rates of HHF and CV mortality versus other GLDs
Cross-sectional and longitudinal analyses of the association between lung function and exercise capacity in healthy Norwegian men
BACKGROUND: It is widely accepted that exercise capacity in healthy individuals is limited by the cardiac function, while the respiratory system is considered oversized. Although there is physiological, age-related decline in both lung function and physical capacity, the association between decline in lung function and decline in exercise capacity is little studied. Therefore, we examined the longitudinal association between lung function indices and exercise capacity, assessed by the total amount of work performed on a standardized incremental test, in a cohort of middle-aged men. METHODS: A total of 745 men between 40 and 59 years were examined using spirometry and standardized bicycle exercise ECG test within "The Oslo Ischemia Study," at two time points: once during 1972-1975, and again, approximately 16 years later, during 1989-1990. The subjects exercise capacity was assessed as physical fitness i.e. the total bicycle work (in Joules) at all workloads divided by bodyweight (in kg). RESULTS: Higher FEV1, FVC and PEF values related to higher physical fitness at both baseline and follow-up (all p values < 0.05). Higher explanatory values were found at follow-up than baseline for FEV1 (r2 = 0.16 vs. r2 = 0.03), FVC (r2 = 0.14 vs. r2 = 0.03) and PEF (r2 = 0.13 vs. r2 = 0.02). No significant correlations were found between decline in physical fitness and declines in FEV1, FVC or PEF. CONCLUSIONS: A weak association between lung function indices and exercise capacity, assessed through physical fitness, was found in middle-aged, healthy men. This association was strengthened with increasing age, suggesting a larger role for lung function in limiting exercise capacity among elderly subjects. However, decline in physical fitness over time was not related to decline in lung function
Healthcare Cost Development in a Type 2 Diabetes Patient Population on Glucose-Lowering Drug Treatment : A Nationwide Observational Study 2006-2014
Objective: The objective of this study was to describe healthcare resource use and cost development in Sweden during 2006-2014 in a type 2 diabetes (T2D) population receiving glucose-lowering drugs (GLDs). Methods: In- and outpatient healthcare resource use and costs were extracted from mandatory national registries: the Cause of Death Register; the National Patient Register; and the Prescribed Drug Register. Primary care data were estimated based on an observational study including patients from 84 primary care centers in Sweden. Numbers of any cause inpatient, outpatient, and primary care contacts were extracted and direct healthcare costs were estimated. Results: During 2006-2014, the number of inpatient and primary care contacts increased by approximately 70% (from 45,559 to 78,245 and from 4.9 to 8.8 million, respectively) and outpatient care contacts almost doubled (from 105,653 to 209,417). Mean annual per patient costs increased by 13%, reaching (sic)4594. Total healthcare costs increased from (sic)835 million to (sic)1.684 billion. Inpatient care costs constituted 47% of total costs in 2014 ((sic)783 million), primary care accounted for 24% ((sic)405 million), outpatient care 18% ((sic)303 million), non-GLD medications 6% ((sic)109 million), and GLDs 5% ((sic)84 million). Cardiovascular diseases (CVDs) were the most costly disease group in inpatient care (26%), whereas managing unspecified factors influencing health and T2D-associated diseases were the most costly in outpatient care (16 and 11%, respectively). Conclusions: The healthcare costs of the GLD-treated T2D population doubled during 2006-2014, mostly driven by the increasing size of this population, of which inpatient care accounted for 47%. GLDs constituted the smallest share of costs. CVD was the most resource-requiring disease group
