Total and component health care costs in a non-Medicare HMO population of patients with and without type 2 diabetes and with and without macrovascular disease.
(57/132)
BACKGROUND: Type 2 diabetes (T2DM) is one of the most prevalent and costly chronic conditions in the United States. Macrovascular disease (MVD) remains a common and costly comorbidity in T2DM. Understanding the impact of MVD on total health care costs in patients with T2DM is of great importance to managed care organizations (MCOs). OBJECTIVE: To examine from the perspective of an MCO the impact of MVD on health care costs in patients with T2DM and in a matched comparison group of patients without diabetes. METHODS: This study involved retrospective analysis of administrative claims (eligibility, pharmacy, and medical) using data from a commercial health maintenance organization population of approximately 700,000 members in an East Coast health plan. Patients were included in this study if they (a) had 2 or more claims for T2DM ( International Classification of Diseases, Ninth Revision, Clinical Modification[ICD-9-CM] codes 250.X0 or 250.X2), or (b) had a prescription drug claim for insulin and a diagnosis of T2DM, or (c) had at least 1 pharmacy claim for an oral glycemic-modifying agent during the 12-month period from January 1, 2003, through December 31, 2003. Patients with 2 or more medical claims for type 1 diabetes (ICD-9-CM codes 250.X1 or 250.X3) were excluded from the study. A random group of comparison patients without diabetes (ICD-9 code 250.xx) were matched on age group and sex. Study patients in these 2 groups were subdivided into 4 groups based on the presence of medical claims with diagnosis codes for MVD (acute myocardial infarction, other ischemic heart disease, coronary artery bypass surgery, percutaneous transluminal angioplasty, congestive heart failure, cerebrovascular accident, peripheral vascular disease, cerebrovascular disease, and peripheral vascular disease). Direct medical costs were aggregated for 12 months after the index date for patients in all 4 groups. Bootstrapping technique was used to compare the health care costs between patients with T2DM and those without diabetes, stratified by MVD status. RESULTS: A total of 9,059 patients with T2DM were identified and were matched by age group and sex to a random group of patients without diabetes. MVD was present in 26.9% (n=2,441) of patients with T2DM versus 11.3% (n=1,027) of patients without diabetes. Patients with MVD and T2DM were, on average, a year younger than patients with MVD but without diabetes (54.55 vs. 55.55 years, P <0.001). Patients with T2DM but without MVD were nearly the same age as patients with neither diabetes nor MVD (50.44 vs. 50.59 years, P=0.092). The T2DM patients with MVD had average 12-month costs more than 3 times the costs for patients with T2DM but without medical claims with diagnosis codes for MVD--10,450 dollars versus 3,385 dollars, respectively. Pharmacy costs accounted for 29.0% and inpatient hospital costs accounted for 43.9% of total medical costs in T2DM patients with MVD versus 55.0% and 17.3%, respectively, in T2DM patients without MVD. Patients with MVD diagnoses and T2DM had total average medical costs that were 1.7 times the total medical costs for MVD patients without T2DM--10,450 dollars versus 6,090 dollars, respectively. CONCLUSIONS: The results of this analysis suggest that MVD may triple the total medical care costs in patients with T2DM. These economic consequences would appear to support the importance of interventions intended to prevent macrovascular events in patients with T2DM. (+info)
Direct and indirect costs of Multiple Sclerosis in Baix Llobregat (Catalonia, Spain), according to disability.
(58/132)
BACKGROUND: Multiple sclerosis (MS) is an incurable chronic disease that predominantly affects young adults. It has a high socio-economic impact which increases as disability progresses. An assessment of the real costs of MS may contribute to our knowledge of the disease and to treat it more efficiently. Our objective is to assess the direct and indirect costs of MS from a societal perspective, in patients monitored in our MS Unit (Baix Llobregat, Catalonia) and grouped according to their disability (EDSS). METHODS: We analysed data from 200 MS patients, who answered a questionnaire on resource consumption, employment and economical status. Mean age was 41.6 years, mean EDSS 2.7, 65.5% of patients were female, 79.5% had a relapsing-remitting course, and 67.5% of them were receiving immunomodulatory treatment (IT). Patients were grouped into five EDSS stages. Data from the questionnaires, hospital charts, Catalan Health Service tariffs, and figures from Catalan Institute of Statistics were used to calculate the direct and indirect costs. The cost-of-illness method, and the human capital approach for indirect costs, were applied. Sensitivity analyses were performed to strengthen results. RESULTS: The mean total annual cost of MS per patient results 24,272 euros. This cost varied according to EDSS: 14,327 euros (EDSS = 0), 18,837 euros (EDSS = 1-3), 27,870 euros (EDSS = 3.5-5.5), 41,198 euros (EDSS = 6-7) and 52,841 euros (EDSS>7.5). When the mean total annual costs was adjusted by the mean % of patients on IT in our Unit (31%) the result was 19589 euros. The key-drivers for direct costs were IT in low EDSS stages, and caregiver costs in high stages. Indirect costs were assessed in terms of the loss of productivity when patients stop working. Direct costs accounted for around 60% of total costs in all EDSS groups. IT accounts from 78% to 11% of direct costs, and decreased as disability progressed. CONCLUSION: The total mean social costs of MS in a cohort from Baix Llobregat (Catalonia) were estimated at 24,272 euros per patient/year, and ranged between 14,327 euros (EDSS = 0) and 52,841 euros (EDSS = 7.5-9.5). Total costs, and particularly informal and direct costs, increased as the disability progressed. IT should be able to delay the progression of disability to be efficient and not only effective.

Cost-utility analysis of short- versus long-course palliative radiotherapy in patients with non-small-cell lung cancer.
(59/132)
BACKGROUND: Radiotherapy can effectively palliate the symptoms of poor-prognosis patients with non-small-cell lung cancer. However, controversy remains about whether short-course or more protracted radiotherapy schedules provide better value for the money. We conducted a societal cost-utility analysis of a Dutch multicenter randomized trial with 1-year follow-up that compared the efficacy of radiotherapy schedules consisting of 10 fractions of 3 Gy (10 x 3 Gy) versus two fractions of 8 Gy (2 x 8 Gy) in 297 patients with inoperable stage IIIA/B or stage IV non-small-cell lung cancer. this trial found that the 10 x 3-Gy group had better survival than the 2 x 8-Gy group. METHODS: Lifetime quality-adjusted life-years (QALYs) were estimated using the EuroQol questionnaire. Lifetime societal costs were estimated using a model estimated based on data from cost questionnaires filled out by a subset of patients (n = 56). Differences were analyzed statistically using two-sided nonparametric bootstrapping. RESULTS: Compared with the 2 x 8-Gy group, the 10 x 3-Gy group accrued statistically significantly more QALYs (20.0 versus 13.2 weeks; difference = 6.8 weeks, 95% confidence interval [CI] = 0.1 to 13.5 weeks, P = .05), which was mainly due to the statistically significantly better survival (38.1 versus 27.4 weeks; difference = 10.7 weeks, 95% CI = 0.9 to 20.6 weeks, P = .03) without a statistically significant difference with respect to the average valuation of health (P = .27). Total radiotherapy and radiotherapy-related costs were estimated at 5236 dollars for the 10 x 3-Gy group and 2512 dollars for the 2 x 8-Gy group (difference = 2724 dollars, 95% CI = 2501 dollars to 2947 dollars, P<.001). The 39% increase in life expectancy in the 10 x 3-Gy group as compared with the 2 x 8-Gy group was associated with a 30% increase in survival-related nonradiotherapy costs (11,254 dollars versus 8651 dollars, difference 2602 dollars, 95% CI = -357 dollars to 5562 dollars, P = .09). The cost-utility ratio for the 10 x 3-Gy schedule versus the 2 x 8-Gy schedule was estimated at 40,900 dollars per QALY (95% CI = 19,400 dollars to 1,100,000 dollars per QALY). CONCLUSIONS: In these poor-prognosis non-small-cell lung cancer patients, the estimated cost-utility ratio for the palliative 10 x 3-Gy schedule was acceptable according to current economic standards. However, the additional costs for the protracted schedule were justified not by improved quality of life but by longer survival. (+info)
Economic evaluation of seizures associated with solitary cysticercus granuloma.
(60/132)
BACKGROUND: Patients with solitary cysticercus granuloma (SCG) develop acute symptomatic seizures because of the inflammatory response of the brain and the seizures are self-limiting. Thus seizure disorder associated with SCG provides a good model to study the total cost of illness (COI). MATERIALS AND METHODS: COI of new-onset seizures associated with SCG was studied in 59 consecutive patients registered at the epilepsy clinic. Direct treatment-related costs and indirect costs, man-days lost and wages lost were evaluated. The relative cost was calculated as the percentage of per capita gross national product (GNP) at current prices for the year 1997-1998. RESULTS: The total COI, for treating seizure disorder associated with SCG per the period of CT resolution of the lesion per patient was INR 7273.7 (US$ 174.66, I$ 943.16) and he/she would be spending 50.9% of per capita GNP The direct cost per patient was INR 5916 (US$ 137.14, 41.4% of per capita GNP). If the patient had received only AEDs for the period of resolution of CT lesion, the cost would be INR 5702.48 (US$132.2, 40% of per capita GNP). The extra expenditure on albendazole and steroid was INR 213.72 (US$ 4.95), 3.6% of the total direct cost and 20.7% of the medication cost. Indirect cost (average wage loss) per patient was INR 1312.7 (US$ 30.42) and it accounted for 9% of per capita GNP. The one-time expenditure at present costs (adjusted for inflation) to the nation to treat all the prevalence cases is to the tune of INR 1.184 billion (US$ 2.605) and 0.0037% of GNP. CONCLUSIONS: This study suggests that seizure disorder associated with SCG, a potentially preventable disorder, is a good model to study the total COI. The one-time expenditure at present costs to the nation to treat all the prevalence cases of seizure disorder associated with SCG is to the tune of INR 1.184 billion (US$ 2.605 million) and 0.0037% of GNP.

Utilization of human papillomavirus testing for cervical cancer prevention in a university hospital.
(61/132)
This study aimed to evaluate the performance and cost of using polymerase chain reaction (PCR) and hybrid capture in the detection of cervical intraepithelial neoplasia (CIN) in patients with cytological abnormalities (ASCUS/low-grade squamous intraepithelial lesion--LSIL), and the feasibility of implementing these methods in Brazil's Unified National Health System (SUS). Colposcopy gave a negative predictive value of 92.86% and efficiency of 87.8% for diagnosing CIN. The sensitivity of PCR and hybrid capture for detecting CIN was 83.33% and 66.67%, respectively, and the negative predictive value for diagnosing CIN2/CIN3 was 100% and 94.74%, respectively. The annual cost for 80 patients was lower when all patients with ASCUS/LSIL were referred for colposcopy than when HPV testing was performed and those with positive results were referred for colposcopy. Therefore, at present, it is financially unfeasible for the National Health System to implement HPV testing to screen patients with cytological abnormalities (ASCUS/LSIL). However, considering that large-scale use might make such methods cheaper, PCR should be the chosen method, since it is less expensive, more sensitive, and has a high negative predictive value.

Update on pharmacoeconomics in transplantation.
(62/132)
PURPOSE: To provide current information on pharmacoeconomic outcomes in transplantation for the past 6 years. METHODS: An extensive literature search was undertaken using PubMed and other authenticated Internet sources. Key words used to elicit pertinent studies were "pharmacoeconomics," "transplantation," "cost-effectiveness," "cost-benefit," "cost-minimization" and "cost-utility" analyses. Studies included in the review contain updated pharmacoeconomic data generated during the past 6 years on economic, clinical, and humanistic outcomes. These data are used to describe and analyze the cost of drug therapy used in transplantation. RESULTS: Background information is included in the review to provide a context from which to evaluate new study material. Data extracted from the studies include significant findings and study limitations. Data were stratified into understanding pharmacoeconomic methods and their application to transplantation, maintenance and induction therapies, and management of and costs associated with adverse events and quality-of-life issues. CONCLUSIONS: Continued evolution of pharmacoeconomic analysis is needed so that optimal care can be provided in the most cost-effective manner. Pharmacoeconomic study, done rationally and logically, is an indispensable tool in determining optimal transplantation regimens. (+info)
Health burden and economic impact of measles-related hospitalizations in Italy in 2002-2003.
(63/132)
BACKGROUND: A large measles outbreak occurred in Italy in 2002-2003. This study evaluates the health burden and economic impact of measles-related hospitalizations in Italy during the specified period. METHODS: Hospital discharge abstract data for measles hospitalizations in Italy during 2002-2003 were analysed to obtain information regarding number and rates of measles hospitalizations by geographical area and age group, length of hospital stay, and complications. Hospitalization costs were estimated on the basis of Diagnosis-Related Groups. RESULTS: A total of 5,154 hospitalizations were identified, 3,478 (67%) of which occurred in children <15 years of age. Most hospitalizations occurred in southern Italy (71 %) and children below 1 year of age presented the greatest hospitalization rates (46.2/100,000 and 19.0/100,000, respectively in 2002 and 2003). Pneumonia was diagnosed in 594 cases (11.5%) and encephalitis in 138 cases (2.7%). Total hospital charges were approximately euro 8.8 million. CONCLUSION: The nationwide health burden associated with measles during the 2002-2003 outbreak was substantial and a high cost was incurred by the Italian National Health Service for the thousands of measles-related hospitalizations which occurred. By assuming that hospital costs represent 40-50% of the direct costs of measles cases, direct costs of measles for the two years combined were estimated to be between 17.6-22.0 million euros, which equates to the vaccination of 1.5-1.9 million children (3-4 birth cohorts) with one dose of MMR. The high cost of measles and the severity of its complications fully justify the commitment required to reach measles elimination. (+info)
Direct costs of asthma in Brazil: a comparison between controlled and uncontrolled asthmatic patients.
(64/132)
Asthma is a common chronic illness that imposes a heavy burden on all aspects of the patient's life, including personal and health care cost expenditures. To analyze the direct cost associated to uncontrolled asthma patients, a cross-sectional study was conducted to determine costs related to patients with uncontrolled and controlled asthma. Uncontrolled patient was defined by daytime symptoms more than twice a week or nocturnal symptoms during two consecutive nights or any limitations of activities, or need for relief rescue medication more than twice a week, and an ACQ score less than 2 points. A questionnaire about direct cost stratification in health services, including emergency room visits, hospitalization, ambulatory visits, and asthma medications prescribed, was applied. Ninety asthma patients were enrolled (45 uncontrolled/45 controlled). Uncontrolled asthmatics accounted for higher health care expenditures than controlled patients, US$125.45 and US$15.58, respectively [emergency room visits (US$39.15 vs US$2.70) and hospitalization (US$86.30 vs US$12.88)], per patient over 6 months. The costs with medications in the last month for patients with mild, moderate and severe asthma were US$1.60, 9.60, and 25.00 in the uncontrolled patients, respectively, and US$6.50, 19.00 and 49.00 in the controlled patients. In view of the small proportion of uncontrolled subjects receiving regular maintenance medication (22.2%) and their lack of resources, providing free medication for uncontrolled patients might be a cost-effective strategy for the public health system.
