The fast-growing prevalence of Parkinson's disease (PD) creates a heavy burden for society and the health care system. Although different ways to mitigate the economic burden of PD have been discussed in the literature, including several effective treatments, few studies have paid attention to the effect of care rehabilitation (CR) on PD costs over a long-term care period. This study tracked medical expenses, care costs, and total costs of elderly individuals with PD for 3 years based on medical claims data merged with long-term care insurance (LTCI) claims data, and determined whether CR reduced PD costs. Using a retrospective, longitudinal cohort design, 3950 elderly individuals with PD who received LTCI services from April 2014 to March 2017 in Fukuoka Prefecture, Japan were followed. PD costs were compared between the CR group and the non-CR group, and a hierarchical linear model was used to examine whether CR was associated with medical expenses, care costs, and total costs. The mean value of total costs in fiscal years 2014, 2015, and 2016 were ¥3,124,944 (US$29,504), ¥3,328,398 (US$31,425), and ¥3,615,892 (US$34,140), respectively. In a hierarchical linear model, CR alone was not associated with medical expenses and care costs; additionally, CR had a positive association with higher total costs. However, the interaction term between CR and baseline care needs level significantly reduced care costs and total costs. That indicates that if older PD patients with higher care needs level receive CR, their care costs and total costs will be reduced. Further research is needed to clarify how CR reduces these patients' costs. [ABSTRACT FROM AUTHOR]

Objective: We aimed to ascertain the degree of influence of income disparity among older people with newly developed dementia on the probability and duration of stay in a hospital or long-term care facility and the degree of influence on medical expenses for hospitalization and care costs.Methods: This was a retrospective cohort study. Study participants included 12 829 individuals aged 75 years or older not diagnosed with dementia between April 2012 and March 2013 but newly diagnosed with dementia between April 2013 and March 2014. Participants were categorized according to income. We evaluated the associations of income with the probability and duration of stay in a hospital or long-term care facility and the costs for hospitalization and care.Results: In the adjusted analyses, high-income individuals had a lower probability of admission to a hospital or long-term care facility than middle- and high-income individuals. In all hospitals, low-income individuals had the longest duration of stay, but in long-term care facilities, income categories varied by facility type. Medical expenses for hospitalization and care costs were highest in the low-income group.Conclusion: Income category affects the probability and duration of stay in the hospital or a long-term care facility, as well as expenses for hospitalization and care. It is necessary to consider a policy to enable low-income older patients with dementia to continue living at home. [ABSTRACT FROM AUTHOR]

This study examined the impact of expenditures for preventive health care services on health care costs among those insured with health insurance societies in Japan using cross-sectional and longitudinal designs. The subjects of the study were those insured with Japan's 1481 health insurance societies belonging to the National Federation of Health Insurance Societies in 2003 and 2007. Multiple regression analyses were conducted using the forced entry method. Case rates, number of service days, and health care costs were used as dependent variables, and preventive health care expenditures, average age, number of the insured, gender ratio, average monthly salary, and dependents ratio were used as independent variables. Expenditures for preventive health care services showed significant negative correlations with both the number of service days and health care costs for inpatient and outpatient services in 2003 and 2007. The results showed that expenditures for preventive health care services had a negative relationship with health care costs. Thus, these findings support the effects of investment in preventive health activities as promoted by health insurance societies to reduce health care costs.

Background: Helicobacter pylori is regarded as an important cause of both peptic ulcer and chronic gastritis. In particular, seropositivity is highest in patients with duodenal ulcer. No studies have determined whether there are differences in the direct medical costs associated with gastric/duodenal ulcer or inflammation, between seropositive and seronegative patients.Objective: To examine the relationship between seropositivity for H. pylori and outpatient visits and direct medical costs for gastric/duodenal ulcer or inflammation in Japan from the perspective of the payor and patients.Methods: Participants were males (n = 653) who worked for an agricultural co-operative in Fukuoka Prefecture, attended an annual health examination (including a written lifestyle and medical survey), belonged to the same health insurance society consistently for 4 years from April 1996 to March 2000, and provided a blood sample. The survey asked about lifestyle, including smoking and drinking, and past medical history. We retrospectively analysed the annual number of outpatient visits per person and outpatient medical cost (Yen, 2000 values) per person for visits relating to gastric or duodenal ulcer or inflammation using International Classification of Diseases (9th edition) -- Clinical Modification codes. We assessed for potential confounding factors using analysis of covariance and the chi-square test.Results: The annual outpatient incidence of disease, the number of visits to physicians, and the medical costs for gastric or duodenal ulcer or inflammation were about 2-fold greater in individuals with antibodies to H. pylori compared with those without antibodies.Conclusion: Population-based studies and/or randomised controlled clinical trials that target high-risk groups and account for the unique way in which data are collected in Japan are needed to determine whether medical costs for gastric and duodenal ulcer might be reduced by treating asymptomatic patients who have antibodies to H. pylori.

The incidence rates of hip fracture have been increasing in Japan. Length of stay among hip fracture patients in Japan is much longer than other developed countries, and the Japanese government introduced financial incentives for regionally coordinated femoral neck fracture care to reduce health care resource utilization. The objective of this study was to evaluate whether the financial incentives reduce health care resource utilization among patients 75 years or older with femoral neck fracture in Japan. Claims data from the Fukuoka Prefecture Regional Association for Late-Stage Healthcare for Older People were analyzed for the period from April 2010 to March 2016. The authors identified 4641 eligible subjects after femoral neck fracture surgery, and categorized them into groups based on care pathways: coordinated care, integrated care, and other. Length of stay by care phase and total charges were used as measures of health care resource utilization. The models showed that coordinated and integrated care were significantly associated with shorter length of stay during perioperative care: coordinated care, multiplicative effect, 0.90 (P < 0.001); integrated care, 0.77 (P < 0.001). However, only integrated care was associated with shorter rehabilitation and overall length of stay: 0.66 (P < 0.001) in rehabilitation; 0.70 (P < 0.001) in overall duration. Integrated care also was associated with lower total charges: 0.70 (P < 0.001). Current financial incentives for regionally coordinated femoral neck fracture care do not affect health care resource utilization. Further health care reforms should be implemented to promote effective regional care coordination in Japan. [ABSTRACT FROM AUTHOR]

The co-payment rate for health care services for insured people increased from 10% to 20% in 1997, and then to 30% in 2003 under the Employed Health Insurance System in Japan. The purpose of this study is to quantify the relationship between average monthly salary and health care service demand by different co-payment rates among the insured of health insurance societies in Japan. Data from the National Federation of Health Insurance Societies from 1996, 2002, and 2007 were analyzed. Indicators of health care service demand included case rates and number of service days per case for inpatient, outpatient, and dental services. The authors evaluated the relationship of average monthly salary with these indicators using multiple regression analyses for each of the 3 years. In the study, the average monthly salary showed a high positive correlation with outpatient and dental case rates for all 3 years. The magnitude of the relationship of average monthly salary to health care service demand was intensified as patient co-payment increased from 10% to 20%. However, it did not change when the co-payment increased from 20% to 30%. The increase in patient co-payment rate from 20% to 30% did not intensify the relationship between average monthly salary and health care service demand among the insured of health insurance societies in Japan.

Objective: To examine the impact of inter-provider care coordination on health-care resource utilization among elderly acute stroke patients.Design: A retrospective cohort study using health-care insurance claims data.Setting: Claims data of the Fukuoka Prefecture Wide-Area Association of Latter-Stage Elderly Healthcare.Participants: About, 6409 patients aged 75 years or older admitted for acute stroke and moved to rehabilitation wards from 1 April 2010 to 30 September 2015.Main Outcome Measure: Lengths of stay (LOS) and total charge (TC) were evaluated according to three groups of care pathways (coordinated care, integrated care and other pathways).Results: Compared with the other care pathway, the coordinated care groups had significantly shorter LOS of 2.0 days in acute ischemic stroke care; they had 2.5 days shorter LOS in hemorrhagic stroke care. However, there were no significant differences in rehabilitation care LOS and TC.Conclusions: Our findings suggest that a payment system for care coordination is inappropriate since it was not associated with a reduction in overall health-care resource utilization. Further, health-care system reform is necessary to improve care continuity across multiple health-care institutions in Japan. [ABSTRACT FROM AUTHOR]
