Core Discrete Event Simulation Model for the Evaluation of Health Care Technologies in Major Depressive Disorder

ObjectiveA review of existing economic models in major depressive disorder (MDD) highlighted the need for models with longer time horizons that also account for heterogeneity in treatment pathways between patients. A core discrete event simulation model was developed to estimate health and cost outcomes associated with alternative treatment strategies.MethodsThis model simulated short- and long-term clinical events (partial response, remission, relapse, recovery, and recurrence), adverse events, and treatment changes (titration, switch, addition, and discontinuation) over up to 5 years. Several treatment pathways were defined on the basis of fictitious antidepressants with three levels of efficacy, tolerability, and price (low, medium, and high) from first line to third line. The model was populated with input data from the literature for the UK setting. Model outputs include time in different health states, quality-adjusted life-years (QALYs), and costs from National Health Service and societal perspectives. The codes are open source.ResultsPredicted costs and QALYs from this model are within the range of results from previous economic evaluations. The largest cost components from the payer perspective were physician visits and hospitalizations. Key parameters driving the predicted costs and QALYs were utility values, effectiveness, and frequency of physician visits. Differences in QALYs and costs between two strategies with different effectiveness increased approximately twofold when the time horizon increased from 1 to 5 years.ConclusionThe discrete event simulation model can provide a more comprehensive evaluation of different therapeutic options in MDD, compared with existing Markov models, and can be used to compare a wide range of health care technologies in various groups of patients with MDD.     

Development of bladder control in children and adolescents with cerebral palsy

The study aimed to investigate the development of bladder control in children with cerebral palsy (CP) and to determinate subgroups with deviant development of bladder control and a higher risk of not achieving urinary continence. Children and adolescents between the ages of 4 and 18 years with a diagnosis of CP, from six Dutch rehabilitation centres were included in the study (n=601). Parents of these participants were sent a questionnaire, of whom 76% responded. Prevalence of primary urinary incontinence was 23.5%. Survival curves were made to determine the development of achieving bladder control in CP. For participants who achieved urinary continence, the development was delayed in comparison with normally developing children and adolescents. The most important factors influencing the occurrence of urinary incontinence in CP were tetraplegia and low intellectual capacity. At age six, 54% of participants with spastic tetraplegia and 80% with spastic hemiplegia or diplegia gained urinary continence spontaneously. Of those who had low intellectual capacity, 38% were dry at this age.     

Evaluation of a follow-up program for mild traumatic brain injury in schoolchildren

Introduction

Mild traumatic brain injury is a common condition in childhood. Although classified as mild, post-concussive symptoms may persist and interfere with daily activities. Because no established guidelines exist with respect to follow-up medical care for these children, there may be a delay in receiving appropriate care. We developed a follow up program to screen for persistent symptoms and if necessary, refer patients for further medical assistance.

Validation of the PHQ-9 as a screening instrument for depression in diabetes patients in specialized outpatient clinics

Background  

For the treatment of depression in diabetes patients, it is important that depression is recognized at an early stage. A screening method for depression is the patient health questionnaire (PHQ-9). The aim of this study is to validate the 9-item Patient Health Questionnaire (PHQ-9) as a screening instrument for depression in diabetes patients in outpatient clinics.     

A microcosting study of diagnostic tests for the detection of coronary artery disease in The Netherlands

Objective

The primary aim of the present study was to calculate the actual costs of four diagnostic tests for the detection of coronary artery disease in the Netherlands using a microcosting methodology. As a secondary objective, the cost effectiveness of eight diagnostic strategies was examined, using microcosting and reimbursement fees subsequently as the cost estimate.

Design

A multicenter, retrospective cost analysis from a hospital perspective.

Setting

The study was conducted in three general hospitals in the Netherlands for 2006.

Interventions

Exercise electrocardiography (exECG), stress echocardiography (sECHO), single-photon emission computed tomography (SPECT) and coronary angiography (CA).

Results

The actual costs of exECG, sECHO, SPECT and CA were €33, 216, 614 and 1300 respectively. For all diagnostic tests, labour and indirect cost components (overheads and capital) together accounted for over 75% of the total costs. Consumables played a relatively important role in SPECT (14%). Hotel and nutrition were only applicable to SPECT and CA. Diagnostic services were solely performed for CA, but their costs were negligible (2%). Using microcosting estimates, exECG-sECHO-SPECT-CA was the most and CA the least cost effective strategy (€397 and 1302 per accurately diagnosed patient). Using reimbursement fees, exECG-sECHO-CA was most and SPECT-CA least cost effective (€147 and 567 per accurately diagnosed patient).

Conclusions

The use of microcosting estimates instead of reimbursement fees led to different conclusions regarding the relative cost effectiveness of alternative strategies.     

The friction cost method for measuring indirect costs of disease

A new approach for estimating the indirect costs of disease, which explicitly considers economic circumstances that limit production losses due to disease, is presented (the friction cost method). For the Netherlands the short-term friction costs in 1990 amount to 1.5-2.5% of net national income (NNI), depending on the extent to which short-term absence from work induces production loss and costs. The medium-term macro-economic consequences of absence from work and disability reduce NNI by an additional 0.8%. These estimates are considerably lower than estimates based on the traditional human capital approach, but they better reflect the economic impact of illness.     

Societal perspective on the burden of migraine in The Netherlands

This study presents a comprehensive overview of the societal burden of migraine in The Netherlands. We assessed the direct and indirect costs of this disease, and the health status of patients with migraine. We developed the 'illness and labour' (I&L) questionnaire to collect data on the effect of illness on labour performance. 846 migraine patients and 834 controls were selected from the general population. Participants completed an I&L questionnaire as well as generic health status questionnaires. The direct costs of migraine amounted to 134 million Netherlands guilders (NLG) [$US1 = NLG1.68, October 1994]. Conservative calculations of the costs of absence from work and reduced productivity at work were NLG264 and NLG277 million per year, respectively. Our study did not indicate that migraine caused household productivity losses. The baseline estimate of the total societal costs of migraine in The Netherlands was NLG675 million per year. The assessment of health status showed considerable impairment of psychological and social functioning in migraine patients.
