The burden of illness of hypopituitary adults with growth hormone deficiency.

OBJECTIVE: The negative metabolic and psychosocial consequences of growth hormone deficiency (GHD) in adults are now well established. In the present study, an attempt was made to quantify the burden of illness, in terms of lost productivity and increased medical consumption, associated with hypopituitarism and untreated GHD. DESIGN AND SETTING: The study population consisted of 129 Belgian adults with untreated GHD associated with hypopituitarism after pituitary surgery. The Short-Form 36 Health Survey (SF-36) was used to assess health status, and the Health and Labour Questionnaire was used to measure production losses and labour performance. Data on medical consumption were also collected. MAIN OUTCOME MEASURES AND RESULTS: Hypopituitary patients reported a lower health status than that of the general population in all but two dimensions of the SF-36 (pain and physical functioning). Nearly 11% of the patients reported being incapacitated for paid employment due to health problems, compared with 4.8% of the general Belgian population. Patients in paid employment reported a mean of 19.8 days of sickness leave per year, which is twice that in the general population. The annual number of visits to general practitioners and specialists was also higher in the patients (9.6 and 6.5 visits, respectively, for the patients compared with corresponding figures of 2.1 and 1.5 for the general Belgian population). The average annual number of days spent in hospital was 3.5 for the patients compared with 2.3 in the general population. The annual healthcare costs and costs due to production losses calculated for hypopituitary patients who had received pituitary surgery amounted to 135,024 Belgian francs (BeF) or $US4340 (1995 values). This compares with the mean annual cost per person for the Belgian population as a whole of BeF68,569 or $US2204. CONCLUSIONS: Hypopituitary patients with untreated GHD therefore have a higher cost to society in terms of lost production and medical consumption than the average Belgian population.     

Healthcare costs of patients with heart failure treated with torasemide or furosemide

OBJECTIVE: To compare the direct healthcare costs of patients with congestive heart failure (CHF) prescribed torasemide (torsemide) or furosemide (frusemide). DESIGN AND SETTING: As part of a prospective, randomised, nonblind study, we assessed the effects of torasemide and furosemide on readmission to hospital in 193 patients treated for CHF at a US urban public healthcare system. We also calculated total direct healthcare costs for the 2 drugs. The perspective of the analysis was that of the healthcare system. Healthcare charge and utilisation data, demographic information, and health status data were obtained from an electronic database containing data for all patients treated within the healthcare system. PATIENTS AND PARTICIPANTS: Upon admission to the hospital, patients were eligible if they had evidence of left ventricular systolic dysfunction, were at least 18 years old, and were receiving furosemide. INTERVENTION: Inpatients were randomised to either torasemide or furosemide treatment for 1 year. MAIN OUTCOME MEASURES AND RESULTS: Patients treated with torasemide had fewer hospital admissions than those treated with furosemide [18 vs 34% for CHF (p = 0.013) and 38 vs 58% for any cardiovascular cause (p = 0.005)]. In the torasemide group, expected annual hospital costs per patient were lower for CHF admissions (by $US1054; 1998 values) and for all cardiovascular admissions (by $US1545) than in the furosemide group. Because the annual acquisition cost of torasemide was $US518 per patient higher than that of furosemide, the resulting net cost saving per patient was $US536 for CHF and $US1027 for all cardiovascular causes. Outpatient costs did not differ between treatment groups regardless of whether drug costs were considered. Total direct costs were $US2124 lower with torasemide than with furosemide (not statistically significant). CONCLUSIONS: Owing largely to reduced readmission to the hospital, the cost of inpatient care for patients with CHF is significantly lower with torasemide than with furosemide, despite the higher acquisition cost of torasemide. Treatment with torasemide resulted in a nonsignificant reduction in total direct costs (outpatient plus inpatient) compared with furosemide.     

Clinical and economic outcomes of olanzapine compared with haloperidol for schizophrenia. Results from a randomised clinical trial.

OBJECTIVE: The purpose of this study was to compare, from the payor perspective, the clinical and economic outcomes of olanzapine to those of haloperidol for the treatment of schizophrenia. DESIGN AND SETTING: Clinical, quality-of-life and resource utilisation data were prospectively collected for US-residing patients with schizophrenia who were participating in a multicentre, randomised, double-blind clinical trial comparing olanzapine and haloperidol. Direct medical costs were estimated by assigning standardised prices (1995 values) to the resource utilisation data. PATIENTS AND PARTICIPANTS: 817 patients with schizophrenia who had a baseline Brief Psychiatric Rating Scale score (BPRS) > or = 18 (items scored 0 to 6) and/or were no longer tolerating current antipsychotic therapy. INTERVENTIONS: Olanzapine 5 to 20 mg/day (n = 551) or haloperidol 5 to 20 mg/day (n = 266) for 6 weeks. Patients showing a predefined level of clinical response entered a 46-week maintenance phase. MAIN OUTCOME MEASURES AND RESULTS: After acute treatment, BPRS-based clinical improvements were seen in 38 and 27% of olanzapine and haloperidol patients, respectively (p = 0.002). Clinically important improvements on the Quality of Life Scale were achieved during acute treatment in 33% of olanzapine recipients and 25% of haloperidol recipients (p = 0.094). Olanzapine treatment in the acute phase led to significantly lower inpatient ($US5125 vs $US5795, p = 0.038) and outpatient ($US663 vs $US692, p = 0.001) costs, resulting in a significant overall reduction in mean total medical costs of $US388 (p = 0.033). This significant reduction in total costs was found despite olanzapine mean medication costs being significantly greater than haloperidol medication costs ($US326 vs $US15, p < 0.001). No significant differences in clinical improvement were observed in the maintenance phase. Maintenance phase olanzapine mean total medical costs were $US636 lower than haloperidol total costs (p = 0.128). Although olanzapine medication costs were significantly higher than haloperidol medication costs ($US3461 vs $US95, p < 0.001), this difference was offset by significantly lower inpatient ($US8322 vs $US10,662, p = 0.044) and outpatient ($US3810 vs $US5473, p = 0.038) costs. CONCLUSIONS: In this study, olanzapine treatment was more effective than haloperidol in producing clinical response in the acute phase. In addition, olanzapine treatment led to reductions in inpatient and outpatient costs that more than offset olanzapine's higher medication costs relative to haloperidol.

Lack of diagnosis and treatment of osteoporosis in men and women after hip fracture

STUDY OBJECTIVE: To determine whether men and women admitted to a university teaching hospital for a low-trauma hip fracture were diagnosed, evaluated, or treated for osteoporosis during admission or for up to 1 year after admission. DESIGN: Retrospective chart review. SETTING: University of Colorado Hospital, Denver, Colorado. PATIENTS: One hundred eighteen patients admitted with a low-trauma hip fracture from January 1993-December 1998. MEASUREMENTS AND MAIN RESULTS: Demographics, medical and social history, prescribed drugs, clinical outcomes, and information regarding the diagnosis, evaluation, and treatment of osteoporosis were abstracted from inpatient medical records for the index hip fracture. Similar data for the first year after the index hip fracture were abstracted from outpatient medical records of patients who had follow-up visits within the hospital system. Mean +/- SD age at the time of fracture was 70 +/- 15 years; 43 patients were men and 75 were women. Eighteen percent of patients had experienced a previous hip fracture, 4% had a history of vertebral fracture, and 6% reported a previous wrist fracture. The diagnosis of osteoporosis was noted in the charts of 14% of the patients at discharge and 26% of patients at follow-up. Only 4% of patients during hospitalization and 9% during follow-up received any evaluative tests for osteoporosis, including bone densitometry. Subsequent fractures occurred in 12.5% of patients. Documented treatment of osteoporosis was uncommon, with approximately 75% of patients receiving no therapy for osteoporosis on discharge or during follow-up. Women were more likely than men to receive a diagnosis of osteoporosis, bone mineral density testing, and osteoporosis drug therapy. CONCLUSION: In patients with hip fractures, osteoporosis is commonly not diagnosed or treated appropriately     

Osteoporotic fractures: a systematic review of U.S. healthcare costs and resource utilization

Osteoporotic fractures are costly in terms of both the dollar amount and healthcare utilization. The objective of this review was to systematically synthesize published evidence regarding direct costs associated with the treatment of osteoporosis-related fractures in the U.S. We conducted a systematic literature review of published studies that used claims databases and economic studies reporting costs associated with osteoporosis-related fractures in the U.S. Studies published between 1990 and 2011 were systematically searched in PubMed (primary source), Ovid HealthSTAR, EMBASE and the websites of large agencies. Data concerning study design, patient population and cost components assessed were extracted with qualitative assessment of study methods, limitations and conclusions. Cost assessment included direct medical and hospitalization (inpatient) costs. The cost differences by age and gender were examined. Of the 33 included studies, 26 reported an estimated total medical cost and hospital resource use associated with osteoporotic fractures. These studies indicated that, in the year following a fracture, medical and hospitalization costs were 1.6-6.2 higher than pre-fracture costs and 2.2-3.5 times higher than those for matched controls. Analysis of the hospitalization costs by osteoporotic fracture type resulted in hip fractures identified as the most expensive fracture type (unit cost range $US 8358-32195), while wrist and forearm fractures were the least expensive (unit cost range $US 1885-12136). Although incremental fracture costs were generally lower in the elderly than in the younger population, total costs were highest for the older (≥65 years of age) population. Total healthcare costs for fractures were highest for the older female population, but unit fracture costs in women were not consistently found to be higher than for men. The qualitative assessment of the included studies demonstrated that the design and reporting of individual studies were of good quality. However, the findings of this review and comparisons across studies were limited by differences in methodologies used by the different studies to derive costs, the populations included in the studies used and the fracture assessment. Despite the variability in estimates, the literature indicates that osteoporosis-related fractures are associated with high total medical and hospitalization costs in the U.S. The variability in the cost estimates highlights the importance of comparing the methodologies and the types of costs used when choosing an appropriate unit cost for economic modelling.     

Olanzapine versus risperidone. A prospective comparison of clinical and economic outcomes in schizophrenia

OBJECTIVE: To compare the clinical and economic outcomes associated with olanzapine and risperidone treatment for schizophrenia. DESIGN AND SETTING: An international, multicentre, double-blind, prospective study. To facilitate economic comparisons, our sample was restricted to patients enrolled in US sites. 150 patients with a Diagnostic and Statistical Manual of mental disorders, 4th edition (DSM-IV) diagnosis of schizophrenia, schizoaffective disorder or schizophreniform disorder were randomised to therapy with either olanzapine 10 to 20 mg/day (n = 75) or risperidone 4 to 12 mg/day (n = 75) for a maximum of 28 weeks. In addition to tolerability and efficacy assessments, use of health services was assessed at baseline and prospectively, at 8-week intervals and at study completion. Clinically important response, defined as a 40% improvement in the Positive and Negative Syndrome Scale total score, maintenance of response and rates of treatment-emergent extrapyramidal symptoms were compared between groups. Direct medical costs were estimated by assigning standardised prices to resource units. Median total, inpatient/outpatient service and medication acquisition costs were compared between treatment groups. MAIN OUTCOME MEASURES AND RESULTS: The mean modal dosages for the olanzapine and risperidone treatment groups were 17.7 +/- 3.4 mg/day and 7.9 +/- 3.2 mg/day, respectively. Olanzapine-treated patients were more likely to maintain response compared with risperidone-treated patients (p = 0.048). In addition, a smaller proportion of olanzapine-treated patients required anticholinergic therapy compared with risperidone-treated patients (25.3 vs 45.3%; p = 0.016). Total per patient medical costs over the study interval were $US2843 (1997 values) [36%] lower in the olanzapine treatment group than in the risperidone treatment group (p = 0.342). Medication costs were significantly higher for olanzapine-treated patients ($US2513 vs $US1581; p < 0.001), but this difference was offset by a reduction of $US3774 (52%) in inpatient/outpatient service costs for olanzapine-treated patients in comparison with risperidone-treated patients ($US3516 vs $US7291, p = 0.083). Median cost findings were consistent with results observed using other robust measures of central tendency and provide conservative estimates of potential savings that may be obtained from olanzapine therapy. CONCLUSIONS: In this study, olanzapine-treated patients experienced clinical improvements that translated into savings in costs of care for both inpatient and outpatient services. These savings offset the difference in medication acquisition cost between olanzapine and risperidone.

The economic impact of Parkinson's disease. An estimation based on a 3-month prospective analysis

OBJECTIVE: This study prospectively assesses the medical costs of Parkinson's disease (PD). DESIGN: Over a period of 3 months (from July to September 1995), patients with PD documented all items of healthcare provision. These data were then used to calculate medical costs for an individual patient as well as the costs of PD. PATIENTS AND SETTING: We included 20 outpatients with idiopathic PD from the neurological outpatient clinic, Klinikum Grosshadern, Munich, and 20 patients from two office-based neurologists in South-West Germany. MAIN RESULTS: The mean 3-month medical cost of PD in 1995 deutschmarks (DM) was 5210 ($US3390, 2240 Pounds) consisting of DM1410 ($US920, 610 Pounds) for care and nursing, DM1580 ($US1030, 680 Pounds) for drug therapy, DM1320 ($US860, 570 Pounds) for inpatient hospital care, DM40 ($US26, 17 Pounds) for outpatient care and DM860 for other expenses ($US560, 370 Pounds). The expenditure was related to the disease evolution. Patients complaining of one-sided symptoms [Hoehn and Yahr stage I; (HY I)] were less expensive to treat (DM1930, $US1250, 830 Pounds) than patients who were severely incapacitated (HY V) [DM9740, $US6330, 4200 Pounds; HY V]. After 3 to 5 years of levodopa treatment approximately 50% of patients start to experience fluctuations in motor ability and dyskinesias [Unified Parkinson's disease rating scale, part IV (UPDRS IV)]. This onset of motor complications parallels an increase in costs. For patients who experienced motor fluctuations, annual costs were DM6550 ($US4260, 2820 Pounds) compared with DM3030 ($US1960, 1300 Pounds) for patients lacking this problem. Indirect non-medical costs were not calculated due to the limited number of patients. The impact of the disease on work, however, is clearly apparent from the patients' history: 19 out of 34 patients who had already stopped working attributed this to the disease, and only 6 patients were still working at the time of the survey. CONCLUSION: PD poses a major financial impact to society which is expected to increase in future years as the age distribution shifts to older age groups. On the basis of a prevalence of PD of 183 per 100,000, we calculated an annual expenditure of DM3.0 billion for the direct medical costs of PD in Germany.     

Economic impact of respiratory syncytial virus-related illness in the US: an analysis of national databases

OBJECTIVE: To determine the impact of respiratory syncytial virus (RSV) infection on healthcare resource use and costs in the US from the third-party payer perspective. DESIGN: The study retrospectively analysed cross-sectional medical encounter data from three federally funded databases that comprise nationally representative samples of hospital inpatient stays, physician office visits and visits to hospital outpatient departments and emergency rooms. METHODS: Identification of RSV infection-related medical encounters was based on the occurrence of RSV-specific International Classification of Diseases (9th Edition)-Clinical Modification diagnosis codes (079.6, 466.11, 480.1) as principal discharge diagnoses or the assumption that 10-15% of all otitis media visits were due to RSV infection. Outpatient drug costs were estimated based on average wholesale price, and physician fees and test/procedure costs were estimated based on prevailing national fees. Inpatient costs were estimated from total billed charges using a cost-to-charge ratio of 0.53. RESULTS: In 2000, nearly 98% of RSV infection-related hospitalisations occurred in children <5 years old. There were approximately 86,000 hospitalisations, 1.7 million office visits, 402 000 emergency room visits and 236,000 hospital outpatient visits for children <5 years old that were attributable to RSV infection. Total annual direct medical costs for all RSV infection-related hospitalisations ($US394 million) and other medical encounters ($US258 million) for children <5 years old were estimated at $US652 million in 2000. Otitis media was a major cost driver for physician visits. RSV infection-related hospitalisations increased from 1993 to 2000, but average costs per hospitalisation were relatively stable. CONCLUSION: Treatment of RSV infection-related illness represents a significant healthcare burden in the US. The economic impact of ambulatory care for RSV infection-related illness could be as important as that for RSV infection-related hospitalisation.     

Cost analysis of the treatment of severe spinal spasticity with a continuous intrathecal baclofen infusion system.

OBJECTIVE: The purpose of our study was to analyse and evaluate the costs of continuous intrathecal baclofen administration as a modality in the treatment of severe spasticity in the Netherlands. DESIGN: A cost analysis was conducted as part of a prospective, multicentre, multidisciplinary, randomised and placebo-controlled clinical trial. The study covered the period from December 1991 to September 1995. The data on medical consumption and costs were collected over a 3-year period from different sources: administrative databases of health insurance companies, hospital registries and a patient survey. These data were structured by means of a flowchart analysis of the medical decision-making by specialists and general practitioners (GPs). They included data on in- and outpatient care, home care and care in nursing homes. The cost analysis was conducted using data from 18 patients included in the trial and from 15 so-called 'match' patients. The latter group are patients with comparable diseases leading to spasticity and living in comparable circumstances. Next to absolute costs (direct and indirect) of care and treatment for the 2 groups of patients, cost differences between the 2 groups were considered (differential cost analysis). SETTING: Per patient cost data, collected prospectively for 2 years during the phase of clinical evaluation, and retrospectively 1 year before implantation. The data were collected on patients from in- and outpatient care, home care and care in nursing home settings. PATIENTS AND PARTICIPANTS: The trial patients (8 men) had a mean age of 46 years; 11 patients had multiple sclerosis and 7 patients had spinal cord injuries. The match patients (7 men) had a mean age of 48 years; 9 patients had multiple sclerosis and 6 patients had spinal cord injuries. INTERVENTIONS: Trial patients were treated with a subcutaneously implanted programmable continuous infusion pump (SynchroMed, Medtronic), filled with baclofen (a muscle relaxant) to treat patients with chronic disabling spasticity who did not respond to a maximum dose of oral baclofen, dantrolene and tizanidine. MAIN OUTCOME MEASURES AND RESULTS: An analysis of hospital stay between both groups showed a significant difference during the implantation year. The average number of hospital days per patient in the year in the treated group was 31.5 days and in the match group was 18.7 days. Significant cost differences between both groups in the year that started with pump implantation and the following year can be attributed mostly to the costs of implantation of the pump and related hospitalisation days. The total costs of patient selection, testing, implanting the pump and follow-up amounted to $US28,473 for the first year. Savings must be taken into consideration as well. The savings of direct costs were due to withdrawal of oral medication (estimated annual total of between $US1950 and $US2800 per patient). Indirect savings on employment and nursing home costs, amounted annually to $US1047 and $US5814, respectively. Scenarios make it possible to consider policy consequences. The case of 'extending' the indications for this treatment to a larger population has been calculated and visualised. CONCLUSIONS: The costs of the therapy (continuous intrathecal infusion of baclofen) can be attributed mostly to implantation of the pump and related hospitalisation days. Savings originated from withdrawal of oral medication, job preservation and avoidance or delay of admission to a nursing home.

Relationship between change in femoral neck bone mineral density and hip fracture incidence during treatment with strontium ranelate

ABSTRACT

Objective: Strontium ranelate (SR) increases bone mineral density (BMD) in postmenopausal osteoporotic women and reduces vertebral and non-vertebral fracture incidence. Hip fracture reduction has also been observed during 3-year treatment with SR in osteoporotic women at high risk of hip fracture. The objective of this study is to analyse the association between BMD changes and hip fracture incidence during treatment with SR.

Material and methods: In this post-hoc analysis, 465 women aged over 74 years with low BMD at the femoral neck (T-score ≤ –2.4 according to NHANES normative values) were selected from the population of a recently published study (the Treatment of Peripheral Osteoporosis Study – TROPOS). BMD was assessed at the femoral neck at baseline and after a follow-up of 3 years. Hip fractures were reported by study investigators.

Results: After adjusting for age, body mass index, femoral neck BMD at baseline and number of prevalent vertebral fractures, we found that for each 1% increase in femoral neck BMD observed after 3 years, the risk to experience a hip fracture after 3 years decreased by 7% (95% CI: 1–14%) (?p = 0.04). In patients experiencing a hip fracture over 3 years of treatment with SR, femoral neck BMD increased by (mean [SE]) 3.41 (1.02)% compared to 7.23 (0.81)% in patients without hip fracture (?p = 0.02).

Conclusion: In this post-hoc analysis of women undergoing 3 years of SR treatment, an increase in femoral neck BMD is associated with a decrease in hip fracture incidence.     

全髋关节置换术与人工股骨头置换术在股骨颈骨折治疗中临床对比分析

目的：对比分析全髋关节置换术与股骨头置换术用于股骨颈骨折治疗的临床疗效。方法：选取2006年5月～2011年3月,我院收治的120例股骨颈骨折患者作为研究对象。按照手术方法的不同,将所有患者随机分为全髋关节置换组和人工股骨头置换组,比较两组患者手术后的并发症情况及术后1个月、3个月、6个月的Harris全髋关节评分,综合评价全髋关节置换术与人工股骨头置换术治疗股骨颈骨折的优劣。结果：两组患者术后并发症比较,全髋关节置换术组并发症发生率明显低于人工股骨头置换术组,术后两组患者的髋关节功能均逐渐恢复,但全髋关节置换术组1个月、3个月、6个月的Harris评分均明显优于人工股骨头置换术组,P值均〈0.05,均具有统计学意义。结论：全髋关节置换术和人工股骨头置换术均是临床治疗股骨颈骨折的有效方法,但究其综合疗效来看,全髋关节置换术较人工股骨头置换术具有一定的优势。
