Family caregiving in dementia and its impact on quality of life and economic burden in Japan-web based survey.

Background: Dementia has become a growing health-care problem in the rapidly ageing Japanese population. This study assesses the impact of dementia on quality of life, economic burden, and productivity loss. Objective: The objective of this study was to assess the impact of dementia on the Quality of Life (QoL), economic burden, and productivity loss among families living with dementia. Methods: An online survey was conducted among families who lived with relatives with dementia. Demographic data and information about health condition and costs of long-term care and treatment were collected. Participants were asked to answer the EuroQol (EQ-5D-5L) questionnaire, Zarit Burden Interview (ZARIT-8), and Work Productivity and Activity Impairment Questionnaire (WPAI). Multivariate analyses were conducted to assess factors associated with burden by families living with dementia. Results: Six hundred and thirty-five participants completed the survey. Of these participants, 50.5% were primary caregivers. Overall, 78.7% of dementia patients suffered from Alzheimer, and 43.9% needed long-term care. Compared to non-primary caregivers, primary caregivers had lower health utility scores (0.896 vs 0.873; p = 0.02), higher burden of caregiving (ZARIT-8: 21.1 vs 24.5; p < 0.0001), and higher overall work impairment (40.2% vs 20.8%; p < 0.0001), absenteeism (15.3% vs 5.7%; p < 0.0001), and presenteeism-related impairment (33.2% vs 17.3%; p < 0.0001). Conclusion: Families living with dementia caring for a person with dementia experience increased burden. Health policies related to dementia need to be considered not only for patients, but also for their families living with dementia to improve their QoL.

Cost-effectiveness of rivaroxaban versus warfarin for stroke prevention in non-valvular atrial fibrillation in the Japanese healthcare setting.

Aims: This article aimed to examine the cost-effectiveness of rivaroxaban in comparison to warfarin for stroke prevention in Japanese patients with non-valvular atrial fibrillation (NVAF), from a public healthcare payer's perspective.Materials and methods: Baseline event risks were obtained from the J-ROCKET AF trial and the treatment effect data were taken from a network meta-analysis. The other model inputs were extracted from the literature and official Japanese sources. The outcomes included the number of ischaemic strokes, myocardial infarctions, systemic embolisms and bleedings avoided, life-years, quality-adjusted life-years (QALYs), incremental costs and incremental cost-effectiveness ratio (ICER). The scenario analysis considered treatment effect data from the same network meta-analysis.Results: In comparison with warfarin, rivaroxaban was estimated to avoid 0.284 ischaemic strokes per patient, to increase the number of QALYs by 0.535 per patient and to decrease the total costs by ¥118,892 (€1,011.11) per patient (1 JPY = 0.00850638 EUR; XE.com, 7 October 2019). Consequently, rivaroxaban treatment was found to be dominant compared to warfarin. In the scenario analysis, the ICER of rivaroxaban versus warfarin was ¥2,873,499 (€24,446.42) per QALY.Limitations: The various sources of data used resulted in the heterogeneity of the cost-effectiveness analysis results. Although, rivaroxaban was cost-effective in the majority of cases.Conclusion: Rivaroxaban is cost-effective against warfarin for stroke prevention in Japanese patients with NVAF, giving the payer WTP of 5,000,000 JPY.

Impact of Patient-Surgeon Relationship on Patient's Return to Work.

BACKGROUND: Upper-limb injuries and musculoskeletal disorders represent a major economic burden for both patients and society, largely due to limitations in returning to work. We hypothesized that a positive patient-surgeon relationship may facilitate patients' recovery and lead to a faster return to work. METHODS: This longitudinal observational study comprised 219 patients, from 8 French hand trauma centers, who were 18 to 55 years of age and were on sick leave from work because of an injury or musculoskeletal disorder of the upper limb. In addition to instruments measuring patients' functional scores and quality of life, the quality of the patient-surgeon relationship was assessed at enrollment using a specific questionnaire (Q-PASREL [Quality of PAtient-Surgeon RELationship]). Six months after enrollment, the return-to-work status was assessed. Logistic and Cox regression models were developed to identify predictors of return to work (yes/no) and the time off from work in days. RESULTS: Overall, 74% of the patients who returned to work within 6 months after enrollment had a high or medium-high Q-PASREL score, whereas 64% of the patients who were still on sick leave had a low or medium-low Q-PASREL score. The odds of patients with a low or medium-low Q-PASREL score returning to work were, respectively, 95% and 71% lower than the odds of patients with a high score doing so, with a percent difference of 56% (95% confidence interval [CI] = 40% to 71%) for low versus high (odds ratio [OR] = 0.05 [95% CI = 0.02 to 0.13]) and 25% (95% CI = 6% to 44%) for medium-low versus high (OR = 0.29 [95% CI = 0.11 to 0.76]). All Q-PASREL items and scores were significantly associated with return to work. CONCLUSIONS: Patients with a lower Q-PASREL score and more severe disability were less likely to return to work within 6 months and had a longer time off from work. Efforts to improve the quality of patient-surgeon relationships may minimize the duration of sick leaves and accelerate patient recovery. LEVEL OF EVIDENCE: Prognostic Level II.

Health-care resource use and current treatment of adult atopic dermatitis patients in Japan: A retrospective claims database analysis.

The real-world evidence on the profiles of patients suffering from atopic dermatitis (AD) in Japan is sparse. A retrospective claim database analysis was conducted to estimate the health-care resource use (HCRU) and current AD treatment. Data from October 2013 to September 2016 were extracted from the JMDC (Tokyo, Japan) claims database. HCRU was assessed by a comparison of AD patients and matched non-AD controls. A multivariate analysis was performed to estimate HCRU attributable to AD. AD patients (n = 39 893) have more claims of certain diagnoses such as rhinitis, viral and fungal infections, sleep disorders and conjunctivitis as well as higher HCRU (outpatient visits, prescriptions of AD-related and non-AD-related medications, phototherapy, laboratory tests) than matched non-AD controls (n = 39 893). Treatment pattern analysis included treatment-naive patients (n = 8478) and previously treated AD patients (n = 30 109). Approximately 20% of previously treated patients were on the continuous systemic treatment during 18-month follow up. Systemic corticosteroids were the most frequently used systemic treatments. Oral cyclosporin was less frequently used in both groups, but for the longest duration. Almost half of previously treated patients with oral cyclosporin continued treatment for more than 3 months. In conclusion, HCRU was higher in AD patients than non-AD controls, indicating a high burden of the disease imposed on AD patients. Continuous administration of systemic treatment, such as oral cyclosporin, systemic corticosteroids and phototherapy, observed in AD patients sheds light on the difficulties of managing AD in Japanese clinical practise.

Estimation of the costs attributable to vitamin K antagonist treatment in patients with non-valvular atrial fibrillation from a French societal perspective.

Background: Little is known about the costs associated with vitamin K antagonist (VKA) treatment in patients with non-valvular atrial fibrillation (NVAF) in France. Objectives: To evaluate monthly per-patient costs attributable to VKA treatment in NVAF patients from a French societal perspective. Study design: Retrospective data were obtained from 7 international normalised ratio (INR) monitoring centres in France. Patients older than 18 years of age with NVAF treated with VKA were recruited. Additional patient-level data assessing resource use corresponding with VKA treatment were collected via self-completed questionnaires. Unit costs applicable to 2015 were multiplied by resource use and summed to generate VKA treatment costs. Results: 363 patients were included; 53% were men. The majority of patients received fluindione (72%). The number of INR tests per patient per month was 1.69 (95% CI, 1.59-1.80). The monthly patient cost was €39.72 (€36.23-43.21) from the French societal perspective. Direct medical costs comprised 76% of overall costs, with drug costs representing 7.4% (€2.4); direct non-medical and indirect costs comprised 10% and 14% respectively. Conclusions: Costs associated with VKA treatment in NVAF cannot be estimated only with drug costs. When direct and indirect attributable costs associated with VKA treatment are considered, the VKA treatment costs are more substantial.

Burden of Anemia in Chronic Kidney Disease Patients in Japan: A Literature Review.

Anemia is a common complication for patients with chronic kidney disease (CKD) and is associated with cardiovascular comorbidities and reduced quality of life. The incidence of anemia increases as kidney function declines and affects approximately 32% of Japanese patients with stage 3-5 CKD. This review examined the current literature on anemia in CKD patients in Japan to provide an overview of the burden of anemia in CKD. Medline, Embase, and Igaku Chuo Zasshi databases were searched to identify relevant manuscripts and abstracts published from 2004 onward. The population included CKD patients with anemia, and the outcomes of interest were epidemiology, economic, humanistic, and treatment patterns. Observational studies, database analysis, and economic evaluation studies were included in the analysis. A total of 1151 references were identified, and 50 were eligible for final review. Economic burden was reported in most studies (n = 37) followed by treatment patterns (n = 26), and epidemiological (n = 25) and humanistic (n = 1) burdens. Prevalence of anemia varied largely (0-95%) based on the different definitions of anemia, and increased with CKD severity. Higher mortality was associated with erythropoiesis-stimulating agent (ESA) resistance and lower hemoglobin levels among patients treated with ESA. Drug dosage was the most reported economic burden (n = 33), followed by medical, and non-medical outcomes. Costs associated with anemia were considerable and depended on dialysis status and ESA treatment. Only one study reported data on quality of life, suggesting that further investigation on the humanistic burden of anemia in CKD is needed.

Cost-effectiveness of droxidopa in patients with neurogenic orthostatic hypotension: post-hoc economic analysis of Phase 3 clinical trial data.

OBJECTIVE: Falls are associated with neurogenic orthostatic hypotension (nOH) and are an economic burden on the US healthcare system. Droxidopa is approved by the US FDA to treat symptomatic nOH. This study estimates the cost-effectiveness of droxidopa vs standard of care from a US payer perspective. METHODS: A Markov model was used to predict numbers of falls and treatment responses using data from a randomized, double-blind trial of patients with Parkinson's disease and nOH who received optimized droxidopa therapy or placebo for 8 weeks. The severity of falls, utility values, and injury-related costs were derived from published studies. Model outcomes included number of falls, number of quality-adjusted life-years (QALYs), and direct costs. Incremental cost-effectiveness ratios (ICERs) were calculated. Outcomes were extrapolated over 12 months. RESULTS: Patients receiving droxidopa had fewer falls compared with those receiving standard of care and gained 0.33 QALYs/patient. Estimated droxidopa costs were $30,112, with estimated cost savings resulting from fall avoidance of $14,574 over 12 months. Droxidopa was cost-effective vs standard of care, with ICERs of $47,001/QALY gained, $24,866 per avoided fall with moderate/major injury, and $1559 per avoided fall with no/minor injury. The main drivers were fall probabilities and fear of fall-related inputs. LIMITATIONS: A limitation of the current study is the reliance on falls data from a randomized controlled trial where the placebo group served as the proxy for standard of care. Data from a larger patient population, reflecting 'real-life' patient use and/or comparison with other agents used to treat nOH, would have been a useful complement, but these data were not available. CONCLUSION: Using Markov modeling, droxidopa appears to be a cost-effective option compared with standard of care in US clinical practice for the treatment of nOH.
