AbstractObjective:To compare the healthcare costs of pre-dialysis chronic kidney disease (CKD) patients cared for in a nephrology clinic setting versus other care settings.Methods:An analysis of health claims between 01/2002 and 09/2007 from the Ingenix Impact Database was conducted. Inclusion criteria were ≥18 years of age, ≥1 ICD-9 claim for CKD, and ≥1 estimated glomerular filtration rate (eGFR) value of <60?mL/min/1.73?m2. Patients were classified in the nephrology care cohort if they were treated in a nephrology clinic setting at least once during the study period. Univariate and multivariate analyses were conducted to compare average annualized healthcare costs of patients in nephrology care versus other care settings.Results:Among the 20,135 patients identified for analysis, 1,547 patients were cared for in a nephrology clinic setting. Nephrology care was associated with lower healthcare costs with an unadjusted cost savings of $3,049 ($11,303 vs. $14,352, p?=?0.0014) and a cost ratio of 0.8:1 relative to other care settings. After adjusting for covariates, nephrology care remained associated with lower costs (adjusted cost savings: $2,742, p?=?0.006).Limitations:Key limitations included potential inaccuracies of claims data, the lack of control for patients’ ethnicity in the calculation of eGFR values, and the presence of potential biases due to the observational design of the study.Conclusions:The current study demonstrated that pre-dialysis CKD patients treated in nephrology clinics were associated with significantly lower healthcare costs compared with patients treated in other healthcare settings. 相似文献

AbstractBackground:To evaluate the cost burden of patients with advanced Parkinson’s disease (PD) according to the waking hours per day spent in OFF state. An analysis of resource use comprising medical services, professional care and informal care data from an observational, cross-sectional study was conducted.Methods:A total of 60 physicians comprising 40 neurologists and 20 geriatricians across the UK participating in the Adelphi PD Disease Specific Programme took part. There were 302 PD patients at H&Y stages 3–5. Patients were characterised according to the percentage of time per day spent in OFF state (<25%, 26–50%, 51–75%, >75%).Results:Average 12-monthly total costs increased according to the time spent in OFF state from £25,630 in patients spending less than 25% of their waking hours in OFF to £62,147 for patients spending more than 75% of their time in OFF. Overall, 7% of costs were attributed to direct medical care, while 93% were split between direct non-medical professional care (50%) and indirect informal care (43%).Limitations:Low patient numbers in the more advanced disease stages of PD led to very little or no data to directly inform some of the severe health states of the analysis. Data gaps were filled in with data derived from a regression analysis which may affect the robustness of the analysis.Conclusion:This study illustrates the increasing costs of advancing PD, in particular related to the time spent in OFF state, and identifies that the foremost cost burden is associated with the care needs of the patient rather than medical services. 相似文献

AbstractObjective:Asthma is one of the most common childhood illnesses and accounts for a substantial amount of pediatric emergency department visits. Historically, acute exacerbations are treated with a beta agonist via nebulizer therapy (NEB). However, with the advent of the spacer, the medication can be delivered via a metered dose inhaler (MDI?+?S) with the same efficacy for mild-to-moderate asthma exacerbations. To date, no study has been done to evaluate emergency department (ED) length of stay (LOS) and opportunity cost between nebulized vs MDI?+?S. The objective of this study was to compare ED LOS and associated opportunity cost among children who present with a mild asthma exacerbation according to the delivery mode of albuterol: MDI?+?S vs NEB.Methods:A structured, retrospective cross-sectional study was conducted. Medical records were reviewed from children aged 1–18 years treated at an urban pediatric ED from July 2007 to June 2008 with a discharge diagnosis International Classification of Disease-9 of asthma. Length of stay was defined: time from initial triage until the time of the guardian signature on the discharge instructions. An operational definition was used to define a mild asthma exacerbation; those patients requiring only one standard weight based albuterol treatment. Emergency department throughput time points, demographic data, treatment course, and delivery method of albuterol were recorded.Results:Three hundred and four patients were analyzed: 94 in the MDI?+?S group and 209 in the NEB group. Mean age in years for the MDI?+?S group was 9.57 vs 5.07 for the NEB group (p?<?0.001). The percentage of patients that received oral corticosteroids was 39.4% in the MDI?+?S group vs 61.7% in the NEB group (p?<?0.001). There was no difference between groups in: race, insurance status, gender, or chest radiographs. The mean ED LOS for patients in the MDI?+?S group was 170 minutes compared to 205 minutes in the NEB group. On average, there was a 25.1 minute time savings per patient in ED treatment time (p?<?0.001; 95% CI?=?3.8–31.7). Significant predictors of outcome for treatment time were chest radiograph, steroids, and treatment mode. Opportunity cost analysis estimated a potential cost savings of $213,532 annually using MDI?+?S vs NEB.Conclusion:In mild asthma exacerbations, administering albuterol via MDI?+?S decreases ED treatment time when compared to administering nebulized albuterol. A metered dose inhaler with spacer utilization may enhance opportunity cost savings and decrease the left without being seen population with improved throughput.Limitations:The key limitations of this study include its retrospective design, the proxy non-standard definition of mild asthma exacerbation, and the opportunity cost calculation, which may over-estimate the value of ED time saved based on ED volume. 相似文献

AbstractBackground:Parkinson’s disease (PD) is the second most common neurodegenerative disease, affecting ~5.2 million people worldwide. Continuous subcutaneous apomorphine (CSAI) represents an alternative treatment option for advanced PD with motor fluctuation. The purpose of this analysis was to estimate the cost-effectiveness of CSAI compared with Levodopa/carbidopa intestinal gel (LCIG), Deep-Brain-Stimulation (DBS) and Standard-of-care (SOC).Methods:A multi-country Markov-Model to simulate the long-term consequences, disease progression (Hoehn & Yahr stages 3–5, percentage of waking-time in the OFF-state), complications, and adverse events was developed. Monte-Carlo simulation accounted for uncertainty. Probabilities were derived from RCT and open-label studies. Costs were estimated from the UK and German healthcare provider’s perspective. QALYs, life-years (LYs), and costs were projected over a life-time horizon.Results:UK lifetime costs associated with CSAI amounts to £78,251.49 and generates 2.85 QALYs and 6.28 LYs (€104,500.08, 2.92 QALYs and 6.49 LYs for Germany). Costs associated with LCIG are £130,011.34, achieves 3.06 QALYs and 6.93 LYs (€175,004.43, 3.18 QALYs and 7.18 LYs for Germany). The incremental-cost per QALY gained (ICER) was £244,684.69 (€272,914.58). Costs for DBS are £87,730.22, associated with 2.75 QALYs and 6.38 LYs (€105,737.08, 2.85 QALYs and 6.61 LYs for Germany). CSAI dominates DBS. SOC associated UK costs are £76,793.49; 2.62 QALYs and 5.76 LYs were reached (€90,011.91, 2.73 QALYs and 6 LYs for Germany).Conclusions:From a health economic perspective, CSAI is a cost-effective therapy and could be seen as an alternative treatment to LCIG or DBS for patients with advanced PD. 相似文献

SummaryRecent advances in HIV antiretroviral therapy together with limited budgets have forced payers to look for evidence that new combinations provide good value for money. Using a public financing perspective, two Markov models are employed to evaluate the first-year outcomes and costs and the long-term cost-effectiveness of adding nevirapine (NVP) to dual combination therapy with zidovudine (ZDV) and didanosine (ddI) in the United Kingdom.First-year medical care savings are estimated to be £2,122 (103.8% of NVP cost). In the longer term, NVP/ZDV/ddI therapy yields £6,186 per life year saved (costs discounted at 6%). The model is moderately sensitive only to duration of therapy effects and the therapy initiation time. These model estimates suggest that policy makers may expect to observe superior initial health outcomes and substantial medical cost savings during the first year of therapy, as well as acceptable long-term cost-effectiveness, when NVP/ZDV/ddI is used in place of dual therapy. 相似文献

SummaryHeart failure (HF) is a serious public health problem worldwide. It has a high prevalence, affects mainly the elderly and causes high mortality or disability with high economic costs. The aim of the present study was to calculate the number of admissions for HF, the total in-hospital stay, the mean length of in-hospital stay and the in-hospital costs due to HF in Belgium.Retrospective analysis of data from the national hospital registration system provided the following results. In 2001, there were 19,398 admissions with HF as a primary diagnosis, with a total in-hospital stay of 286,938 days. The mean in-hospital stay for HF was 14.8 days. The total in-hospital cost of HF as a primary diagnosis was € 94,113,827, representing 1.8% of the total hospital expenditure.The limitations of this study are its mere focus on admissions and their characteristics in 2001, and the use of a retrospective analysis. Nevertheless, it led to the conclusion that HF was responsible for a significant number of in-hospital days, with a significant impact on healthcare costs in Belgium. 相似文献

论分税制下财政转移支付与地方财政努力差异——基于功能与地区多重分类考察的另类荷兰病分析 总被引:3,自引:0,他引:3
文章主要研究分税制下政府间转移支付与地区财政努力差异的关系.通过理论模型推导和对转移支付的实证检验发现:中国现行转移支付制度在总体上抑制了地方政府的财政努力.就区域效果而言,转移支付在促进东部发达省份财政努力的同时,抑制了中、西部落后地区的财政努力;就转移支付的功能类型而言,以税收返还为主的条件性转移支付会激励地方政府努力征税,而非条件性转移支付,包括财力性和专项转移支付将不同程度地抑制地方财政努力.这就产生了挤出效应与另类"荷兰病"的问题. 相似文献

In recent years, the continuous structural change in the value chain of modern food production has been characterised by an increasing international division of labour among manufacturing companies. A regional specialisation of primary agricultural production is especially apparent in meat production. Thus, the German–Dutch border area has developed into a region of unprecedented intensive pork production. While The Netherlands specialises in piglet production, the production of fattened pigs continues to grow in northwest Germany. As a result of this increasing transnational value chain development, German imports of Dutch piglets have risen continuously since 2000. However, this structural interweaving of pork production between The Netherlands and Germany has resulted in many new challenges for the cooperation between the various participants and in particular for the administrative authorities in the field of food and feed safety as well as efficient animal disease control. The motivation for this exploratory study stems from the lack of scientific work on this topic to date. The aim of this research is to illustrate the relevance of functioning cross-border cooperation in the food sector, using commodity flow structures and disease spread analysis. Results indicate that cross-border cooperation between authorities during a CSF epidemic can reduce the risk of recurrence and the duration by 50%. 相似文献

城市的发展有其特定的内在规律性,其产生、发展、消亡的各个过程都是作为一个有机体变化更新的特定阶段。集聚效应和扩散效应是经济中心城市的两个主要功能。两者不同的机理分别产生"城市病"问题和内城问题。在城市化发展的过程中,集聚效应要先于扩散效应发生,因此内城问题往往产生于城市化后期。在城市的发展进程中,内城问题在表现特征上有着一些与"城市病"问题截然不同的方面,有其特殊的解决对策。 相似文献
