Healthcare cost variation in patients with heart failure: a nationwide study.

OBJECTIVE: Heart failure (HF) imposes a major economic burden; however, the individual management for patients varies, potentially leading to large cost heterogeneity. The aim of this study was to investigate the spectrum of health cost by patients with HF and factors associated with high direct health cost. STUDY DESIGN: This was a nationwide, retrospective longitudinal study. METHODS: Using Danish nationwide registries from 2012 to 2015, we identified all patients aged >18 years with a first-time diagnosis of HF. Total health costs were investigated using two perspectives-at index and during 3 years of follow-up. Patients were investigated by decile cost groups. A multivariable logistic regression was used to identify variables associated with being in the highest cost decile compared with the rest (90%). RESULTS: A total of 11,170 patients with HF were included, and those in the highest cost decile (n = 1117, 10%) were younger (69 vs. 75 years), fewer were females (34% vs. 43%), and more were inpatients (83% vs. 70%) compared with the rest of the patients with HF (n = 10,053, 90%). Patients in the highest cost decile (10%) incurred a 30 times higher cost with a mean total health cost in index year of €86,607 compared with €2893 for patients in lowest cost decile (10%). The results were similar for 3 years aggregated (€139,473 vs. €4086), corresponding to a 34 times higher cost. CONCLUSION: In patients with HF, a large total health cost heterogeneity exists with younger age, inpatient admittance, male sex, and comorbidities being associated with a higher likelihood of belonging to the highest cost group.

Evaluation of the effectiveness of liraglutide and sitagliptin in type 2 diabetes: a retrospective study in UK primary care.

OBJECTIVE: Type 2 diabetes is a chronic condition that continues to increase in prevalence in the UK. Incretin-based therapies, including liraglutide and sitagliptin, provide adequate blood glucose control. Clinical trials have shown that liraglutide offers greater glycaemic control and body weight reduction in comparison to sitagliptin. We aimed to assess the effectiveness of liraglutide and sitagliptin in routine clinical practice. MATERIALS AND METHODS: We designed and conducted a retrospective database analysis in primary care using the Clinical Practice Research Datalink in the UK. Patients aged ≥ 18 years, diagnosed with type 2 diabetes and prescribed liraglutide or sitagliptin between July 2009 and July 2012, were included in the study. Glycaemic and weight control were investigated 6 months after treatment initiation. RESULTS: A total of 287 liraglutide and 2781 sitagliptin patients were identified. Compared with sitagliptin, liraglutide recipients had greater reductions in HbA1c (%) (-0.90 vs. -0.57, p < 0.01), weight (kg) (-3.78 vs. -1.12, p < 0.001), BMI (kg/m(2) ) (-1.30 vs. -0.39, p < 0.001) and systolic blood pressure (mmHg) (-3.91 vs. -0.39, p < 0.001) after 6 months of treatment. When controlling for potential confounders, liraglutide was more likely than sitagliptin to achieve an HbA1c reduction ≥ 1% (OR = 2.29, 95% CI 1.62-3.25), an HbA1c reduction ≥ 1% and a weight reduction ≥ 3% (OR = 2.99; 95% CI 2.00-4.48) and a target HbA1c < 7% (OR = 2.11; 95% CI 1.45-3.07) after 6 months of treatment. CONCLUSIONS: Clinical trials show superior glycaemic control and weight reduction with liraglutide compared with sitagliptin. This finding is reflected in routine clinical practice in the UK.
