Cost-effectiveness analysis of memantine for moderate-to-severe Alzheimer’s disease in the Netherlands

Objective: The purpose of this study was to estimate the cost-effectiveness of memantine relative to standard care in patients with moderate-to-severe Alzheimer's disease in the Netherlands. Methods: A country-adapted five-year Markov model simulated disease progression through a series of states, defined by dependency and disease severity. Transition probabilities were derived from trials, with utility and epidemiological data obtained from a longitudinal Dutch cohort. Cost-effectiveness was described in terms of quality-adjusted life years and time spent in a nondependent state or in a moderate severity state. Results: Memantine monotherapy versus standard care led to 0.058 quality-adjusted life years gained (1.207 versus 1.265), longer time in a nondependent state (from 1.602 to 1.751 years) and in a moderate state (from 2.051 to 2.141 years), and no additional costs (€ 113,927 versus € 110,097). Robustness of results was confirmed through sensitivity analyses. Conclusion: Memantine is dominant compared with standard care in the Netherlands. Results are consistent with similar economic evaluations in other countries

Cost for Treatment of Chronic Lymphocytic Leukemia in Specialized Institutions of Ukraine

AbstractObjectiveThe aim of this study was to identify, from a health care perspective, the cost of treatment for chronic lymphocytic leukemia in specialized hospitals in Ukraine.MethodsCost analysis was performed by using retrospective data between 2006 and 2010 from patient-file databases of two specialized hospitals (145 patients). Uncertainty was assessed by using bootstrapping and multivariate sensitivity analyses. Linear regression analysis was used to analyze whether patients’ characteristics are related to health care costs. In addition, one-way analysis of variance (Welch test) and paired-sample t test were conducted to compare mean costs of treatment between the two hospitals and mean expenses for drugs and in-hospital stay.ResultsThe average annual cost for a patient’s drug treatment is 2047 EUR. The cost of hospitalization was significantly lower (t = 5.026; significance two-tailed = 0.000) and equal to 541 EUR per person, resulting in total expenditures of 2589 EUR. Mean total costs in the bootstrap analysis were equal to 2584 EUR (median 2576 EUR, 97.5th percentile 3223 EUR; 2.5th percentile 1987 EUR). The regression analysis did not reveal a relation between patients’ characteristics and health care costs, although hospital choice was an influential parameter (β = −0.260; significance = 0.002). Significant difference in mean costs of two analyzed hospitals was also confirmed by one-way analysis of variance (Welch statistics 19.222, P = 0.000).ConclusionsDrug treatment comprises the largest portion of total costs, but differences between hospitals exist. Because many patients in Ukraine pay out of pocket for in-hospital drugs, these costs are a high economic burden for patients with chronic lymphocytic leukemia

The feasibility and efficacy of a multidisciplinary intervention with aftercare meetings for fibromyalgia

The objective of this study is to examine the feasibility and long-term results of a 12-week multidisciplinary part-time daycare intervention with five aftercare meetings in fibromyalgia (FM) patients. One hundred and five patients diagnosed with FM started with a multidisciplinary intervention and were assessed for feasibility, functional status (Fibromyalgia Impact Questionnaire [FIQ]), and quality of life (EuroQol-5D [EQ-5D]) until 9 months after completion. The program consisted of sociotherapy, physiotherapy, psychotherapy, and creative arts therapy. Drop-out rate was 4.8%. The attendance rate of 100 patients who completed the 12-week program and five aftercare meetings was high (97.4%), just like patient and therapist satisfaction (8.2 on a 10 points scale). After the 12-week program, statistically significant improvement was seen in both FIQ and EQ-5D. This improvement was maintained after 9 months of follow-up. On average, moderate improvements were observed. Our 12-week multidisciplinary part-time daycare intervention with five aftercare meetings for FM patients is feasible and it is indicated that it can lead to sustained improvement in functional status and quality of life

Health care input constraints and cost effectiveness analysis

Results of cost effectiveness analyses (CEA) studies are most useful for decision makers if they face only one constraint: the health care budget. However, in practice, decision makers wishing to use the results of CEA studies may face multiple resource constraints relating to, for instance, constraints in health care inputs such as a shortage of skilled labour. The presence of multiple resource constraints influences the decision rules of CEA and limits the usefulness of traditional CEA studies for decision makers. The goal of this paper is to illustrate how results of CEA can be interpreted and used in case a decision maker faces a health care input constraint. We set up a theoretical model describing the optimal allocation of the health care budget in the presence of a health care input constraint. Insights derived from that model were used to analyse a stylized example based on a decision about a surgical robot as well as a published cost effectiveness study on eye care services in Zambia. Our theoretical model shows that applying default decision rules in the presence of a health care input constraint leads to suboptimal decisions but that there are ways of preserving the traditional decision rules of CEA by reweighing different cost categories. The examples illustrate how such adjustments can be made, and makes clear that optimal decisions depend crucially on such adjustments. We conclude that it is possible to use the results of cost effectiveness studies in the presence of health care input constraints if results are properly adjusted

Care coordination in a business-to-business and a business-to-consumer model for telemonitoring patients with chronic diseases

Introduction For telemonitoring to support care coordination, a sound business model is conditional. The aim of this study is to explore the systemic and economic differences in care coordination via business-to-business and business-to-consumer models for telemonitoring patients with chronic diseases. Methods We performed a literature search in order to design the business-to-business and business-to-consumer telemonitoring models, and to assess the design elements and themes by applying the activity system theory, and describe the transaction costs in each model. The design elements are content, structure, and governance, while the design themes are novelty, lock-in, complementarities, and efficiency. In the transaction cost analysis, we looked into all the elements of a transaction in both models. Results Care coordination in the business-to-business model is designed to be organized between the places of activity, rather than the participants in the activity. The design of the business-to-business model creates a firm lock-in but for a limited time. In the business-to-consumer model, the interdependencies are to be found between the persons in the care process and not between the places of care. The differences between the models were found in both the design elements and the design themes. Discussion Care coordination in the business-to-business and business-to-consumer models for telemonitoring chronic diseases differs in principle in terms of design elements and design themes. Based on the theoretical models, the transaction costs could potentially be lower in the business-to-consumer model than in the business-to-business, which could be a promoting economic principle for the implementation of telemonitoring

Cost-effectiveness of a nurse-led telemonitoring intervention based on peak expiratory flow measurements in asthmatics: results of a randomised controlled trial

ABSTRACT: BACKGROUND: Asthma is a chronic lung disease in which recurrent asthma symptoms create a substantial burden to individuals and their families. At the same time the economic burden associated with asthma is considerable. METHODS: The cost-effectiveness study was part of a single centre prospective randomised controlled trial comparing a nurse-led telemonitoring programme to usual care in a population of asthmatic outpatients. The study included 109 asthmatic outpatients (56 children; 53 adults). The duration of follow-up was 12 months, and measurements were performed at baseline, 4, 8, and 12 months. Patients were asked to transfer their monitor data at least twice daily and by judging the received data and following a stepwise intervention protocol a nurse was able to act as the main caregiver in the intervention group. In both groups the EQ-5D and the SF-6D were used to obtain estimates of health state utilities. One year health care costs, patient and family costs, and productivity losses were calculated. The mean incremental costs were weighted against the mean incremental effect in terms of QALY. RESULTS: The study population generally represented mild to moderate asthmatics. No significant differences were found between the groups with regard to the generic quality of life. Overall, the mean health care costs per patient were higher in the intervention group than in the control group. The intervention costs mainly caused the cost difference between the groups. The intervention costs the society euro 31,035/QALY gained with regard to adults and with regard to children euro 59,071/QALY gained. CONCLUSION: If the outcome is measured by generic quality of life the nurse-led telemonitoring programme is of limited cost-effectiveness in the study population. From the societal perspective the probability of the programme being cost-effective compared to regular care was 85% at a ceiling ratio of euro 80,000/QALY gained among the adults and 68% among the children. A decrease in the price of the asthma monitor will substantial increase the probability of the programme to be cost-effective. TRIAL REGISTRATION: Number: NCT00411436

Performance of the EQ-5D and the EQ-5D+C in elderly patients with cognitive impairments

<p>Abstract</p> <p>Background</p> <p>The EQ-5D is a reliable tool for measuring Health-Related Quality of Life (HRQoL). However, concern has been expressed that it may ignore elements of HRQoL, particularly cognition. In response to this concern, the EQ-5D has been extended with a cognitive dimension (EQ-5D+C). The aim of this study was to compare the performance of the EQ-5D and the EQ-5D+C in elderly patients with cognitive impairments by assessing their construct validity and responsiveness.</p> <p>Methods</p> <p>Data from the MEDICIE study (n = 196) were used, in which all questionnaires were rated by proxies.</p> <p>Results</p> <p>Regarding construct validity, we found similar correlations between the EQ-5D and the Mini Mental State Examination (MMSE) and between the EQ-5D+C and the MMSE. Furthermore, both the EQ-5D and the EQ-5D+C were responsive to changes in the MMSE, with the EQ-5D performing slightly better.</p> <p>Conclusion</p> <p>We conclude that the EQ-5D performs well for evaluating HRQoL in a population with cognitive impairments. Based on the results of this explorative study, it does not seem necessary to adjust the current classification system by adding a cognitive dimension. However, in order to compare both instruments regarding utility values, it is necessary to develop a new scoring algorithm for the EQ-5D+C by conducting a general population study. Considering the explorative nature of this study, it is recommended that more aspects of the validity of both the EQ-5D and the EQ-5D+C are explored in patients with cognitive impairments using a more tailored study design.</p

Improving management of patients with acute cough by C-reactive protein point of care testing and communication training (IMPAC(3)T): study protocol of a cluster randomised controlled trial

BACKGROUND: Most antibiotic prescriptions for acute cough due to lower respiratory tract infections (LRTI) in primary care are not warranted. Diagnostic uncertainty and patient expectations and worries are major drivers of unnecessary antibiotic prescribing. A C-reactive protein (CRP) point of care test may help GPs to better guide antibiotic treatment by ruling out pneumonia in cases of low test results. Alternatively, enhanced communication skills training to help clinicians address patients' expectations and worries could lead to a decrease in antibiotic prescribing, without compromising clinical recovery, while enhancing patient enablement. The aim of this paper is to describe the design and methods of a study to assess two interventions for improving LRTI management in general practice. METHODS/DESIGN: This cluster randomised controlled, factorial trial will introduce two interventions in general practice; point of care CRP testing and enhanced communication skills training for LRTI. Twenty general practices with two participating GPs per practice will recruit 400 patients with LRTI during two winter periods. Patients will be followed up for at least 28 days. The primary outcome measure is the antibiotic prescribing rate. Secondary outcomes are clinical recovery, cost-effectiveness, use of other diagnostic tests and medical services (including reconsultation), and patient enablement. DISCUSSION: This trial is the first cluster randomised trial to evaluate the influence of point of care CRP testing in the hands of the general practitioner and enhanced communication skills, on the management of LRTI in primary care. The pragmatic nature of the study, which leaves treatment decisions up to the responsible clinicians, will enhance the applicability and generalisability of findings. The factorial design will allow conclusion to be made about the value of CRP testing on its own, communication skills training on its own, and the two combined. Evaluating a biomedical and communication based intervention ('hard' and 'soft' technologies) together in this way makes this trial unique in its field

Cost-effectiveness of tailored print communication, telephone motivational interviewing, and a combination of the two: results of an economic evaluation alongside the Vitalum randomized controlled trial

<p>Abstract</p> <p>Background</p> <p>The aim of the present study was to evaluate the cost-effectiveness of tailored print communication (TPC), telephone motivational interviewing (TMI), a combination of the two, and no intervention on two outcomes in adults aged 45 to 70, half of them having hypertension: increasing the number of public health guidelines met for three behaviors (physical activity and fruit and vegetable consumption), and impact on quality adjusted life years (QALYs).</p> <p>Methods</p> <p>Participants (<it>n </it>= 1,629) from 23 Dutch general practices were randomized into one of four groups, which received 4 TPCs, 4 TMIs, 2 of each (combined), or no intervention (control), respectively. The self-reported outcomes, measured at baseline and 73 weeks follow-up (7 months after the last intervention component), were difference in total number of guidelines met at follow-up compared to baseline, and number of QALYs experienced over 73 weeks. The costs of implementing the intervention were estimated using a bottom-up approach.</p> <p>Results</p> <p>At 73 weeks follow-up participants showed increased adherence with 0.62 (TPC), 0.40 (TMI), 0.50 (combined), and 0.26 (control) guidelines compared to baseline, and experienced 1.09, 1.08, 1.08, and 1.07 QALYs, respectively. The costs for the control group were considered to be zero. TMI was more expensive (€107 per person) than both the combined intervention (€80) and TPC (€57). The control condition was most cost-effective for lower ceiling ratios, while TPC had the highest probability of being most cost-effective for higher ceiling ratios (more than €160 per additional guideline met, and €2,851 for each individual QALY).</p> <p>Conclusions</p> <p>For low society's willingness to pay, the control group was most cost-effective for the number of QALYs experienced over 73 weeks. This also applied to the increase in the number of guidelines met at lower ceiling ratios, whereas at higher ceiling ratios, TPC had a higher probability of being more cost-effective than the TMI, combined or control conditions. This also seemed to apply for QALYs experienced over 73 weeks. More research is needed on the long-term efficacy of both TPC and TMI, as well as on how to increase their cost-effectiveness.</p> <p>Trial registration</p> <p>Dutch Trial Register NTR1068</p

The impact of structural uncertainty on cost-effectiveness models for adjuvant endocrine breast cancer treatments: The need for disease-specific model standardization and improved guidance

__Abstract__ Introduction: Structural uncertainty relates to differences in model structure and parameterization. For many published health economic analyses in oncology, substantial differences in model structure exist, leading to differences in analysis outcomes and potentially impacting decision-making processes. The objectives of this analysis were (1) to identify differences in model structure and parameterization for cost-effectiveness analyses (CEAs) comparing tamoxifen and anastrazole for adjuvant breast cancer (ABC) treatment; and (2) to quantify the impact of these differences on analysis outcome metrics. Methods: The analysis consisted of four steps: (1) review of the literature for identification of eligible CEAs; (2) definition and implementation of a base model structure, which included the core structural components for all identified CEAs; (3) definition and implementation of changes or additions in the base model structure or parameterization; and (4) quantification of the impact of changes in model structure or parameterizations on the analysis outcome metrics life-years gained (LYG), incremental costs (IC) and the incremental cost-effectiveness ratio (ICER). Results: Eleven CEA analyses comparing anastrazole and tamoxifen as ABC treatment were identified. The base model consisted of the following health states: (1) on treatment; (2) off treatment; (3) local recurrence; (4) metastatic disease; (5) death due to breast cancer; and (6) death due to other causes. The base model estimates of anastrazole versus tamoxifen for the LYG, IC and ICER were 0.263 years, €3,647 and €13,868/LYG, respectively. In the published models that were evaluated, differences in model structure included the addition of different recurrence health states, and associated transition rates were identified. Differences in parameterization were related to the incidences of recurrence, local recurrence to metastatic disease, and metastatic disease to death. The separate impact of these model components on the LYG ranged from 0.207 to 0.356 years, while incremental costs ranged from €3,490 to €3,714 and ICERs ranged from €9,804/LYG to €17,966/LYG. When we re-analyzed the published CEAs in our framework by including their respective model properties, the LYG ranged from 0.207 to 0.383 years, IC ranged from €3,556 to €3,731 and ICERs ranged from €9,683/LYG to €17,570/LYG. Conclusion:
