Cost-effectiveness of mass screening for dipstick hematuria in Japan.

BACKGROUND: Dipstick urine tests are a simple and inexpensive method for detecting kidney and urological diseases, such as IgA nephropathy and bladder cancer. The nationwide mass screening program, Specific Health Checkup (SHC), started in Japan in 2008 and targeted all adults between 40 and 74 years of age. Dipstick urine tests for proteinuria and glucosuria are mandatory as part of the SHC, but dipstick urine tests for hematuria are not. However, the dipstick hematuria test is often administered simultaneously with these mandatory tests by some health insurers. Hematuria is common in Japanese general screening participants, particularly elderly women, and the necessity of mass screening using the dipstick hematuria test has been discussed. This study aimed to evaluate the cost-effectiveness of mass screening for dipstick hematuria tests in addition to the SHC. METHODS: Using a decision tree and Markov modeling, we conducted a cost-effectiveness analysis from a Japanese societal perspective. RESULTS: Compared with the current SHC, mass screening for dipstick hematuria tests, in addition to the SHC, costs less and gains more, which means cost-saving. Similar findings were observed in the sex-specific analysis. CONCLUSION: Our results suggest that mandating the dipstick hematuria test could be justifiable as an efficient use of finite healthcare resources. The results have implications for mass screening programs not only in Japan but worldwide.

Behaviour modification intervention for patients with chronic kidney disease could provide a mid- to long-term reduction in public health care expenditure: budget impact analysis.

BACKGROUND: A recent cost-effectiveness analysis (CEA) study evaluated the widespread diffusion of behaviour modification intervention for patients with chronic kidney disease (CKD). Incorporating this behaviour modification intervention, comprising educational sessions on nutrition/lifestyle and support for regular patient visits, to the current CKD guideline-based practice was found to be cost-effective. This study aimed to examine the affordability of this efficient new practice under the hypothesis that the behaviour modification intervention would be initiated by general physicians (GPs). METHODS: A budget impact analysis was conducted by defining the target population as patients aged 40-74 years with stage-3-5 CKD based on the prevalence of definitive CKD in the Japanese general population. Costs expended by social insurers without discount were counted as budgets. We estimated the annual budget impact for 15 years by running our CEA model, assuming that it would be good for the span. RESULTS: We estimated the number of patients with end-stage kidney disease (ESKD) to decrease by 4,496 in the fifteenth year of the new practice using our CEA model. Compared to that in the current practice, the budget impact as total additional expenditure of the new practice was estimated to be negative by the tenth year in the base case. CONCLUSIONS: The widespread diffusion of behaviour modification intervention would contain public health care expenditure over the mid-to-long term, resulting from a reduction in progression to ESKD. We suggest that providing sufficient economic incentives to GPs and strengthening recommendations in CKD guidelines would realise effective GP-initiated interventions.

Cost-Effectiveness of Behavior Modification Intervention for Patients With Chronic Kidney Disease in the FROM-J Study.

OBJECTIVES: Chronic kidney disease (CKD) is a significant public health problem. An advanced, or innovative, CKD care system of clinical practice collaboration among general physicians (GPs), nephrologists, and other healthcare workers achieved behavior modification in patients with Stage 3 CKD in the Frontier of Renal Outcome Modifications in Japan (FROM-J) study. This behavior modification intervention consisted of educational sessions on nutrition and lifestyle, as well as encouragement of patients' regular visits. The intervention contributed to slowing CKD progression. This study aimed to evaluate the cost-effectiveness of the widespread diffusion of the behavior modification intervention proven effective by the FROM-J study. METHODS: A cost-effectiveness analysis was carried out to compare the behavior modification intervention with the current practice recommended by the latest CKD clinical guidelines for GPs. A Markov model with a societal perspective under Japan's health system was constructed. We assumed that the behavior modification intervention proven effective by the FROM-J study would be initiated by GPs for targeted patient cohorts-patients aged 40-74 years with Stage 3 CKD-as a part of the innovative CKD care system. RESULTS: The incremental cost-effectiveness ratio for the behavior modification intervention compared with current guideline-based practice was calculated as 145,593 Japanese yen (¥; $1,324 United States dollars [$]) per quality-adjusted life year (QALY). CONCLUSIONS: Using the suggested value of social willingness to pay for a one-QALY gain in Japan of ¥5 million (US$45,455) as the threshold to judge cost-effectiveness, the behavior modification intervention is cost-effective. Our results suggest that diffusing the behavior modification intervention proven effective by the FROM-J study could be justifiable as an efficient use of finite healthcare resources. GPs could be encouraged to initiate this intervention by revising the National Health Insurance fee schedule and strengthening clinical guidelines regarding behavior modification interventions.

Cost-effectiveness of obstructive sleep apnea screening for patients with diabetes or chronic kidney disease.

PURPOSE: Obstructive sleep apnea (OSA) is a common disorder with a high prevalence among patients with cardiovascular disease (CVD), diabetes, and chronic kidney disease (CKD). Routine evaluation of OSA for patients with CVD including hypertension has been performed according to the clinical guidelines for both OSA and CVD. However, most patients with diabetes and CKD who could benefit from treatment remain undiagnosed because routine screening of OSA is not recognized as part of standard practice. This study aims to evaluate the cost-effectiveness of OSA screening for patients with diabetes and CKD. METHODS: Cost-effectiveness analysis by a decision tree and Markov modeling from the societal perspective in Japan was carried out to provide evidence based on the economic evaluation of current clinical practice concerning diabetes and CKD. RESULTS: Incremental cost-effectiveness ratios of OSA screening compared with do-nothing were calculated as ¥3,516,976 to 4,514,813/quality-adjusted life year (QALY) (US$35,170 to 45,148/QALY) for diabetes patients and ¥3,666,946 to 4,006,866/QALY (US$36,669 to 40,069/QALY) for CKD patients. CONCLUSIONS: Taking the threshold to judge cost-effectiveness according to a suggested value of social willingness to pay for one QALY gain in Japan as ¥5 million/QALY (US$50,000QALY), OSA screening is cost-effective. Our results suggest that active case screening and treatment of OSA for untreated middle-aged male patients with diabetes or CKD could be justifiable as an efficient use of finite health-care resources in the world with high prevalence of these diseases.

Budget impact analysis of chronic kidney disease mass screening test in Japan.

BACKGROUND: Our recently published cost-effectiveness study on chronic kidney disease mass screening test in Japan evaluated the use of dipstick test, serum creatinine (Cr) assay or both in specific health checkup (SHC). Mandating the use of serum Cr assay additionally, or the continuation of current policy mandating dipstick test only was found cost-effective. This study aims to examine the affordability of previously suggested reforms. METHODS: Budget impact analysis was conducted assuming the economic model would be good for 15 years and applying a population projection. Costs expended by social insurers without discounting were counted as budgets. RESULTS: Annual budget impacts of mass screening compared with do-nothing scenario were calculated as ¥79-¥-1,067 million for dipstick test only, ¥2,505-¥9,235 million for serum Cr assay only and ¥2,517-¥9,251 million for the use of both during a 15-year period. Annual budget impacts associated with the reforms were calculated as ¥975-¥4,129 million for mandating serum Cr assay in addition to the currently used mandatory dipstick test, and ¥963-¥4,113 million for mandating serum Cr assay only and abandoning dipstick test. CONCLUSIONS: Estimated values associated with the reform from ¥963-¥4,129 million per year over 15 years are considerable amounts of money under limited resources. The most impressive finding of this study is the decreasing additional expenditures in dipstick test only scenario. This suggests that current policy which mandates dipstick test only would contain medical care expenditure.

Cost-effectiveness analysis of pertussis booster vaccination for adolescents in Japan.

INTRODUCTION: In Japan, the introduction of a fifth diphtheria-tetanus-acellular pertussis (DTaP) vaccination has been considered, and adolescents aged 11-12 years old who are currently receiving the diphtheria-tetanus (DT) vaccine are one candidate group. We analyze the cost-effectiveness of replacing the DT vaccine with the DTaP vaccine for 11-year-old adolescents and investigate the indirect effect of vaccinated adolescents on unvaccinated infant siblings. We undertake two analyses using high- and low-morbidity pertussis cases, and based on the results, present suggestions for pertussis prevention in the post-COVID-19 pandemic era. METHOD: We used the number of pertussis cases in 2019 as the high-morbidity case and the average number of cases in 2020-2021 as the low-morbidity case, and evaluated the incremental cost-effectiveness ratio (ICER) of the DTaP strategy to the DT strategy based on quality-adjusted life years (QALYs). The economic model contained adolescent and infant sub-models. The indirect effect for infants was considered as the probability of unvaccinated infants avoiding pertussis infection from their vaccinated siblings. RESULTS: The ICER from the payers' perspective was Japanese yen (JPY) 4,254,515 per QALY gained in the high-morbidity case and JPY 62,546,776 per QALY gained in the low-morbidity case. The sensitivity analysis showed that the utility of pertussis had the greatest impact on the ICER, with a 60.58% and 0% probability that the ICER was less than JPY 5 million per QALY gained in the high-morbidity case and low-morbidity case, respectively. CONCLUSION: The cost-effectiveness of replacing the DT vaccine with the DTaP vaccine is affected by the level of pertussis morbidity, with the ICER becoming more favorable in the high-morbidity case. The indirect effect has little impact on the ICER. Thus, policy-makers should continue to monitor the pertussis epidemic in the post-COVID-19 era, and determine the need to introduce a booster based on perceived trends.

Subsidy Programs for Seasonal Influenza Vaccination of Children and Pregnant Women in Japanese Municipalities.

In Japan, influenza vaccination is offered to children and pregnant women at clinics or hospitals as an elective, self-funded treatment, as the vaccination is not included in the national vaccination subsidy program. However, some Japanese municipalities offer a discretionary subsidy for seasonal influenza vaccination of children and pregnant women as a local policy. We identified these local subsidy programs during 2019/2020 seasonal influenza season by conducting a cross-sectional survey across Japan. Out of a total of 1741 municipalities, responses were received from 1732; therefore, the response rate was 99.5%. The local influenza vaccine subsidy programs for children were offered in 45.7%, and for pregnant women in 10.2%, of Japanese municipalities. This is the first survey of subsidy programs for pregnant women. While policy diffusion of subsidy programs for children was observed during the 9 years since a previous study, such programs for pregnant women remain limited. Despite many municipalities having subsidy programs, we found that their provision still remains limited when viewed as a whole.

Cost-effectiveness of professional and mechanical oral care for preventing pneumonia in nursing home residents.

BACKGROUND: Pneumonia is common in nursing home residents and is a leading cause of hospitalization and death. Nursing home residents with cerebrovascular diseases and impaired consciousness are at high risk of aspiration pneumonia. Professional and mechanical oral care by dentists and hygienists in addition to daily oral care by caregivers was shown to be effective in preventing pneumonia in nursing home residents. However, professional and mechanical oral care has not been widely provided in Japan, while daily oral care by caregivers has been widely provided as a basic service in nursing homes. This study aimed to evaluate the cost-effectiveness of providing professional and mechanical oral care for preventing pneumonia in nursing home residents. METHODS: Using a decision tree and Markov modeling, we conducted a cost-effectiveness analysis from the payer's perspective (social insurers and patients) in Japan. RESULTS: The incremental cost-effectiveness ratio for professional and mechanical oral care compared with daily oral care only was calculated as 4,079,313 Japanese yen (¥; 33,994 United States dollars [US$], US$1 = ¥120) per quality-adjusted life year. CONCLUSIONS: Using the official value of social willingness to pay for a one-quality-adjusted life year gain in Japan of ¥5 million (US$41,667) as the threshold to judge cost-effectiveness, providing professional and mechanical oral care is cost-effective. Our results suggest professional and mechanical oral care for preventing pneumonia in nursing home residents could be justifiable as efficient use of finite healthcare resources. The results have implications for oral care in nursing homes both in Japan and worldwide.

Analysis of the cost-effectiveness of proton beam therapy for unresectable pancreatic cancer in Japan.

BACKGROUND: Proton beam therapy (PBT) has recently been included in Japan's social health insurance benefits package. This study aimed to determine the cost-effectiveness of PBT for unresectable, locally advanced pancreatic cancer (LAPC) as a replacement for conventional photon radiotherapy (RT). METHODS: We estimated the incremental cost-effectiveness ratio (ICER) of PBT as a replacement for three-dimensional conformal RT (3DCRT), a conventional photon RT, using clinical evidence in the literature and expense complemented by expert opinions. We used a decision tree and an economic and Markov model to illustrate the disease courses followed by LAPC patients. Effectiveness was estimated as quality-adjusted life years (QALY) using utility weights for the health state. Social insurance fees were calculated as the costs. The stability of the ICER against the assumptions made was appraised using sensitivity analyses. RESULTS: The effectiveness of PBT and 3DCRT was 1.67610615 and 0.97181271 QALY, respectively. The ICER was estimated to be ¥5,376,915 (US$46,756) per QALY. According to the suggested threshold for anti-cancer therapy from the Japanese authority of ¥7,500,000 (US$65,217) per QALY gain, such a replacement would be considered cost-effective. The one-way and probabilistic sensitivity analyses demonstrated stability of the base-case ICER. CONCLUSION: PBT, as a replacement for conventional photon radiotherapy, is cost-effective and justifiable as an efficient use of finite healthcare resources. Making it a standard treatment option and available to every patient in Japan is socially acceptable from the perspective of health economics.

Economic evaluation of the 70-gene prognosis-signature (MammaPrint®) in hormone receptor-positive, lymph node-negative, human epidermal growth factor receptor type 2-negative early stage breast cancer in Japan.

The 70-gene prognosis-signature is validated as a good predictor of recurrence for hormone receptor-positive (ER+), lymph node-negative (LN-), human epidermal growth factor receptor type 2-negative (HER2-) early stage breast cancer (ESBC) in Japanese patient population. Its high cost and potential in avoiding unnecessary adjuvant chemotherapy arouse interest in its economic impact. This study evaluates the cost-effectiveness of including the assay into Japan's social health insurance benefit package. An economic decision tree and Markov model under Japan's health system from the societal perspective is constructed with clinical evidence from the pool analysis of validation studies. One-way sensitivity analyses are also performed. Incremental cost-effectiveness ratio is estimated as ¥3,873,922/quality adjusted life year (QALY) (US$43,044/QALY), which is not more than the suggested social willingness-to-pay for one QALY gain from an innovative medical intervention in Japan, ¥5,000,000/QALY (US$55,556/QALY). However, sensitivity analyses show the instability of this estimation. The introduction of the assay into Japanese practice of ER+, LN-, HER2- ESBC treatment by including it to Japan's social health insurance benefit package has a reasonable chance to be judged as cost-effective and may be justified as an efficient deployment of finite health care resources.

Cost-effectiveness of chronic kidney disease mass screening test in Japan.

BACKGROUND: Chronic kidney disease (CKD) is a significant public health problem. Strategy for its early detection is still controversial. This study aims to assess the cost-effectiveness of population strategy, i.e. mass screening, and Japan's health checkup reform. METHODS: Cost-effectiveness analysis was carried out to compare test modalities in the context of reforming Japan's mandatory annual health checkup for adults. A decision tree and Markov model with societal perspective were constructed to compare dipstick test to check proteinuria only, serum creatinine (Cr) assay only, or both. RESULTS: Incremental cost-effectiveness ratios (ICERs) of mass screening compared with do-nothing were calculated as ¥1,139,399/QALY (US $12,660/QALY) for dipstick test only, ¥8,122,492/QALY (US $90,250/QALY) for serum Cr assay only and ¥8,235,431/QALY (US $91,505/QALY) for both. ICERs associated with the reform were calculated as ¥9,325,663/QALY (US $103,618/QALY) for mandating serum Cr assay in addition to the currently used mandatory dipstick test, and ¥9,001,414/QALY (US $100,016/QALY) for mandating serum Cr assay and applying dipstick test at discretion. CONCLUSIONS: Taking a threshold to judge cost-effectiveness according to World Health Organization's recommendation, i.e. three times gross domestic product per capita of ¥11.5 million/QALY (US $128 thousand/QALY), a policy that mandates serum Cr assay is cost-effective. The choice of continuing the current policy which mandates dipstick test only is also cost-effective. Our results suggest that a population strategy for CKD detection such as mass screening using dipstick test and/or serum Cr assay can be justified as an efficient use of health care resources in a population with high prevalence of the disease such as in Japan and Asian countries.

Demand for pneumococcal vaccination under subsidy program for the elderly in Japan.

BACKGROUND: Vaccination programs often organize subsidies and public relations in order to obtain high uptake rates and coverage. However, effects of subsidies and public relations have not been studied well in the literature. In this study, the demand function of pneumococcal vaccination among the elderly in Japan is estimated, incorporating effects of public relations and subsidy. METHODS: Using a data from a questionnaire survey sent to municipalities, the varying and constant elasticity models were applied to estimate the demand function. The response variable is the uptake rate. Explanatory variables are: subsidy supported shot price, operating years of the program, target population size for vaccination, shot location intensity, income and various public relations tools. The best model is selected by c-AIC, and varying and constant price elasticities are calculated from estimation results. RESULTS: The vaccine uptake rate and the shot price have a negative relation. From the results of varying price elasticity, the demand for vaccination is elastic at municipalities with a shot price higher than 3,708 JPY (35.7 USD). Effects of public relations on the uptake rate are not found. CONCLUSIONS: It can be suggested that municipalities with a shot price higher than 3,708 JPY (35.7 USD) could subsidize more and reduce price to increase the demand for vaccination. Effects of public relations are not confirmed in this study, probably due to measurement errors of variables used for public relations, and studies at micro level exploring individual's response to public relations would be required.

Cost-effectiveness of pertussis booster vaccination for preschool children in Japan.

INTRODUCTION: Japan currently recommends four doses of the diphtheria-tetanus-acellular pertussis (DTaP) vaccine in its routine vaccination program, but the introduction of a fifth dose is currently under consideration. An objective of the booster vaccination is to prevent severe cases of pertussis in infants through herd immunity. Thus, the aim of this analysis was to demonstrate the cost-effectiveness of a fifth-dose of the DTaP vaccine for 6-year-old children, taking herd immunity for unvaccinated infants into account. METHOD: An economic model analysis was conducted comparing the cost and effectiveness of the two strategies based on quality-adjusted life years (QALYs). We evaluated the incremental cost-effectiveness ratio (ICER) of the booster strategy to the no booster strategy. This model contained two sub-models: one for children aged 6 years or older and one for infants under 3 months old. Herd immunity for infants is modeled as when siblings in the same family are infected. RESULTS: The ICER was JPY 71,605,491 (USD 656,931) per QALY gained from the societal perspective, and 7.10% of incremental QALYs (0.0000934) were from a reduction in infant infection. In the sensitivity analysis, no variables moved the ICER under the threshold (JPY 5,000,000 per QALY gained), and the duration of pertussis disease and the incidence rate of pertussis had a significant impact on the ICER. When the disease burden of pertussis decreased, the booster strategy resulted in fewer QALYs gained and greater costs compared with the no booster strategy. CONCLUSION: The introduction of a DTaP booster vaccination to the routine immunization schedule can be expected to reduce the number of pertussis cases in the target population. However, our study showed that adding a booster vaccination for 6-year-old children to the schedule in Japan would not be cost-effective in terms of achieving herd immunity among unvaccinated infants.

Cost-effectiveness analyses of 15- and 20-valent pneumococcal conjugate vaccines for Japanese elderly.

BACKGROUND: Despite the 23-valent pneumococcal polysaccharide vaccine (PPSV23) vaccination programme implementation, pneumococcal disease (PD) remains an important cause of morbidity and mortality among the elderly in Japan, particularly since childhood pneumococcal conjugate vaccine (PCV) vaccination programme continues to alter the serotype PD distribution among the elderly. Recently, in the United States, PCV15/PCV20 were recommended for adults aged ≥ 65 years and those aged 19-64 years with certain underlying conditions. In Japan, PCV15 is under the approval application process and PCV20 undergoing clinical trials, which has warranted the need in evaluating their value for money. METHODS: We conducted cost-effectiveness analyses with Markov model and calculated incremental cost-effectiveness ratios of PCV15/PCV20 vaccination programme compared to status quo from payers' perspective. Transition probabilities and utility weights in estimating quality-adjusted life-year (QALY), and disease treatment costs were either estimated or obtained from literature. To reflect the situation of COVID-19 pandemic, epidemiological data from 2020 and beyond were used. RESULTS: Compared to the current vaccination programme, PCV20 vaccination programme gained more QALYs with less cost, while PCV15 vaccination programme cost ¥35,020 (US$318, US$1 = ¥110) to gain an additional QALY. Replacing PPSV23 vaccination programme with PCV20 vaccination programme is cost-saving. One-way sensitivity analyses revealed that lower VE limits of PCVs against non-bacteremic pneumonia (NBP) have large impact to change the result from PCV20 vaccination programme dominated PPSV23 vaccination programme to PPSV23 vaccination programme dominated PCV20 vaccination programme. CONCLUSION: In the COVID-19 era, replacing current PPSV23 with a single-dose PCV15- or PCV20 immunisation programme for 65-year-old adults in Japan is highly cost-effective, while the PCV 20 vaccination programme was observed to be more favourable.

Cost-effectiveness analyses of monovalent mumps vaccination programs for Japanese children.

BACKGROUND: The most common preventative measure against mumps is vaccination with mumps vaccine. Over 122 countries have implemented mumps vaccine routine immunization programs, mostly via Measles-Mumps-Rubella (MMR) vaccine. In Japan, the unexpectedly high incidence of aseptic meningitis caused by mumps vaccine led to the discontinuation of the MMR national vaccination program in 1993, inadvertently resulting in the re-emergence of mumps. Plans of introducing monovalent mumps vaccine into routine vaccination schedule have become one of the emerging topics in health policy that has warranted the need in evaluating its value for money. METHODS: We conducted cost-effectiveness analyses with Markov model and calculated incremental cost-effectiveness ratios (ICERs) of two different vaccination programs (a single-dose program at one-year-old, a two-dose program with second dose uptakes at five) compared to status quo from both payers' and societal perspectives. Transition probabilities and utility weights in estimating quality-adjusted life-year (QALY), and disease treatment costs were either estimated or obtained from literature. Costs per vaccination were assumed at ¥6140 (US$58;1US$ = ¥106). RESULTS: Both programs reduce disease treatment costs compared to status quo, while the reduction cannot offset vaccination cost. ICER of either program is found to be under ¥5,000,000 (US$47,170)/QALY willingness-to-pay (WTP) threshold from either perspective. Results of probabilistic sensitivity analyses expressed by net monetary benefit indicated that at the WTP threshold, the acceptability is at 92.6% for two-dose vaccination program, 0% for single-dose vaccination program, and 7.4% for current no vaccination program. Two-dose program was optimal among the alternatives. One-way sensitivity analyses revealed that proportion of mumps-related hearing loss among mumps cases and vaccine effectiveness (VE) were key variables in changing the ICERs. CONCLUSION: Routine vaccination program of single- and two-dose programs were cost-effective from both payers' and societal perspectives. Between the two, the two-dose vaccination program was observed to be more favorable.

Economic evaluation of the 21-gene signature (Oncotype DX) in lymph node-negative/positive, hormone receptor-positive early-stage breast cancer based on Japanese validation study (JBCRG-TR03).

The 21-gene signature is validated as a good predictor of recurrence for lymph node-negative/positive, hormone receptor-positive, early-stage breast cancer in Japanese patient population. This study evaluates the cost-effectiveness of two scenarios designed to include the assay into Japan's social health insurance benefit package: one for LN-, ER+, ESBC and another for LN-/+, ER+, ESBC. An economic decision tree and Markov model under Japan's health system from the societal perspective is constructed with new evidence from the Japanese validation study. Incremental cost-effectiveness ratios are estimated as ¥384,828 (US$3,848) per QALY for the indication for LN- scenario and ¥568,533 (US$5,685) per QALY for the indication for LN-/+ scenario. Both are not more than the suggested social willingness-to-pay for one QALY gain from an innovative medical intervention in Japan, ¥5,000,000/QALY (US$50,000/QALY). Sensitivity analyses show that this result is plausibly robust, since ICERs do not exceed the threshold by various changes of assumptions made and values employed. In conclusion, the inclusion of the assay in Japan's social health insurance benefit package for not only LN- diseases but also LN+ diseases is cost-effective. Such a decision can be justifiable as an efficient use of finite resources for health care.

Budget impact analysis reveals walk-in fingertip HbA1c testing in community pharmacies could provide a significant long-term reduction in public expenditure.

In Japan, a new opportunistic community-based walk-in HbA1c testing program at pharmacies was enabled in 2014. An economic evaluation of this program from societal perspective has previously been published. This study examines the effect of a subsidy program for walk-in HbA1c-testing at community pharmacies in Japan on public health care expenditure by conducting a budget impact analysis from payer's perspective. The study focused on Adachi Ward in Tokyo, where a pioneering subsidy program was implemented. It examined the budget impact of the subsidy program over a 15 years. The total subsidy paid by the local authority during the first year was 2909 USD. Public expenditure remained positive for the first five years before becoming negative in the sixth year, eventually resulting in savings of 221,000 USD in the 15th year. The cost of treating type 2 diabetes that is detected early is offset by a reduction in expensive treatments for complicated cases. Subsidizing walk-in fingertip HbA1c testing in community pharmacies is likely to result in a significant reduction in public expenditure over the mid-to long term. Our result suggests that a similar strategy in other areas could also have a potentially favorable budget impact.

[Cost-effectiveness analysis of pre-seasonal medication for cedar pollinosis in Japan].

Pre-seasonal medication is recommended for cases of cedar pollinosis that are expected to manifest severe symptoms during the season, according to the standard clinical guideline in Japan. This study aims to appraise the value for money of additional costs that accompany the choice of pre-seasonal medication from payer's perspective. Based on the 12 reports of controlled clinical trials with Symptom Score (SS) and Medication Score (MS) comparing pre-seasonal medication with intra-seasonal symptomatic medication, 15 incremental cost-effectiveness ratios (ICERs) and 4 integrated ICERs of each group of targeted agents are estimated. Incremental effects are estimated by reading SS charts, and incremental costs are estimated by reading MS charts and using National Health Insurance Medical Fee Schedule and National Health Insurance Drug Price Standard. Estimated ICERs range from ¥322,195 per quality-adjusted life-year (QALY) to ¥57,088,063 per QALY. Integrated ICERs are: ¥1,128,286 per QALY for 2nd generation histamine H(1) receptor antagonists, ¥2,248,018 per QALY for leukotriene receptor antagonists, ¥2,692,911 per QALY for prostaglandin D(2) and thromboxane A(2) receptor antagonists, ¥1,150,943 per QALY for Th2 cytokine suppressors, and ¥1,291,341 per QALY for all agents. Pre-seasonal medication for cedar pollinosis is cost-effective regardless of the choice of the prophylactic agent among 2nd generation histamine H(1) receptor antagonists, leukotriene receptor antagonists, prostaglandin D(2) and thromboxane A(2) receptor antagonists, or Th2 cytokine suppressors, taking the suggested threshold of ¥5,000,000 per 1 QALY gain in Japan. The use of 2nd generation histamine H(1) receptor antagonists and Th2 cytokine suppressors are found more favourable.

[Pricing and uptake rate of public funded pneumococcal vaccination for the elderly in Japan].

PURPOSE: The number of municipalities that offer a pneumococcal pneumonia vaccine (PPV) to their aged inhabitants has been increasing. In this study, a complete count survey of the practice of municipality-organized PPV vaccination programs was carried out to explore co-payment/subsidy levels and uptake rates. METHOD: A questionnaire inquiring into the price charged to the vaccinee, the subsidy provided by the municipality, the size of the target population, and the numbers of individuals vaccinated from 2001 to 2007 was sent to 63 municipal authorities which had organized PPV vaccination programs. Annual changes of co-payment/subsidy and uptake rates are examined with analysis of variance (excluding the year with n < or = 2). RESULTS: The number of municipalities that provided a subsidy was 1 in 2001, 2 in 2002, 18 in both 2003 and 2004, 24 in 2005, 41 in 2006, and 56 in 2007. Average levels of subsidy were 3233 yen in 2003, 3225 yen in 2004, 3168 yen in 2005, 3158 yen in 2006, and 3351 yen in 2007. Average levels of co-payment are 3899 yen in 2003, 3928 yen in 2004, 3979 yen in 2005, 3891 yen in 2006 and 3672 yen in 2007. No significant differences were found among average levels of subsidy/co-payment between consecutive years (F = 0.195, p = 0.964/F = 0.271, p = 0.949). Average uptake rates by number of years since the beginning of the program (response rate 68.1%, 109/160) were 17.7% for the 1st-year, and 5.4%, 3.7%, 3.4%, 4.6% for the 2nd- to 5th-years, respectively. Statistically significant differences were observed between the 1st- and each of the following years (Dunnett T3, p < 0.001). Average uptake rates in the first year of the program (response rate 80.9%, 51/63) were 32.1% in 2003, 8.5% in 2005, 13.6% in 2006 and 16.5% in 2007. Significant differences were observed between 2003 and 2005 (Tukey's HSD, p = 0.03), and 2003 and 2006 (Tukey's HSD, P = 0.015). CONCLUSION: Our results revealed levels of co-payment/subsidy and uptake rates of municipality-organized PPV vaccination programs for the first time.
