Inadvertently boarding a pirate ship: disease progression in a paediatric patient with relapsed metastatic Ewing sarcoma receiving treatment at a centre for alternative therapy in Mexico.

Complementary and alternative medicine (CAM) therapies are commonly incorporated into the care of patients with paediatric cancer. Many modalities are safe and effective during cancer treatment and have proved beneficial for symptom relief and quality of life. However, situations where alternative therapy is provided without allopathic medical care supportive care resources can pose a safety risk to patients. This report describes the case of a 16-year-old Chinese girl with metastatic Ewing sarcoma who sought treatment with alternative treatment in Mexico. When her disease progressed with an ensuing significant loss of function, the centre personnel were unable to respond to her acute deterioration or provide necessary medical care. This resulted in her being stranded in a foreign country paralysed, isolated, and with large unanticipated financial expenditures.

Is Prophylactic Intervention More Cost-effective Than the Treatment of Pathologic Fractures in Metastatic Bone Disease?

BACKGROUND: Metastatic bone disease is a substantial burden to patients and the healthcare system as a whole. Metastatic disease can be painful, is associated with decreased survival, and is emotionally traumatic to patients when they discover their disease has progressed. In the United States, more than 250,000 patients have metastatic bone disease, with an estimated annual cost of USD 12 billion. Prior studies suggest that patients who receive prophylactic fixation for impending pathologic fractures, compared with those treated for realized pathologic fractures, have decreased pain levels, faster postoperative rehabilitation, and less in-hospital morbidity. However, to our knowledge, the relative economic utility of these treatment options has not been examined. QUESTIONS/PURPOSES: We asked: (1) Is there a cost difference between a cohort of patients treated surgically for pathologic fractures compared with a cohort of patients treated prophylactically for impending pathologic lesions? (2) Do these cohorts differ in other ways regarding their utilization of healthcare resources? METHODS: We performed a retrospective study of 40 patients treated our institution. Between 2011 and 2014, we treated 46 patients surgically for metastatic lesions of long bones. Of those, 19 (48%) presented with pathologic fractures; the other 21 patients (53%) underwent surgery for impending fractures. Risk of impending fracture was determined by one surgeon based on appearance of the lesion, subjective symptoms of the patient, cortical involvement, and location of the lesion. At 1 year postoperative, four patients in each group had died. Six patients (13%) were treated for metastatic disease but were excluded from the retrospective data because of a change in medical record system and inability to obtain financial records. Variables of interest included total and direct costs per episode of care, days of hospitalization, discharge disposition, 1-year postoperative mortality, and descriptive demographic data. All costs were expressed as a cost ratio between the two cohorts, and total differences between the groups, as required per medical center regulations. All data were collected by one author and the medical center's financial office. RESULTS: Mean total cost was higher in patients with pathologic fractures (cost unit [CU], 642 ± 519) than those treated prophylactically without fractures (CU, 370 ± 171; mean difference, 272; 95% CI, 19-525; p = 0.036). In USD, this translates to a mean of nearly USD 21,000 less for prophylactic surgery. Mean direct cost was 41% higher (nearly USD 12,000) in patients with a pathologic fracture (CU, 382 ± 300 versus 227 ± 93; mean difference, 155; 95% CI, 9-300; p = 0.038). Mean length of stay was longer in patients with pathologic fractures compared with the group treated prophylactically (8 ± 6 versus 4 ± 3 days; mean difference, 4; 95% CI, 1-7; p = 0.01). CONCLUSIONS: These findings show economic and clinical value of prophylactic stabilization of metastatic lesions when performed for patients with painful lesions compromising the structural integrity of long bones. Patients sustaining a pathologic fracture may represent a more severe, sicker demographic than patients treated for impending pathologic lesions. LEVEL OF EVIDENCE: Level IV, economic and decision analysis.

Cost of skeletal complications from bone metastases in six European countries.

Objective Patients with bone metastases or lesions secondary to solid tumors or multiple myeloma often experience bone complications (skeletal-related events [SREs]-radiation to bone, pathologic fracture, surgery to bone, and spinal cord compression); however, recent data that can be used to assess the value of treatments to prevent SREs across European countries are limited. This study aimed to provide estimates of health resource utilization (HRU) and cost associated with all SRE types in Europe. HRU data were reported previously; cost data are reported herein. Methods Eligible patients from 49 centers across Austria (n = 57), the Czech Republic (n = 59), Finland (n = 60), Greece (n = 59), Portugal (n = 59), and Sweden (n = 62) had bone metastases or lesions secondary to breast, lung, or prostate cancer, or multiple myeloma, and ≥1 index SRE (a SRE preceded by a SRE-free period of ≥ 6.5 months). SRE-related costs were estimated from a payer perspective using health resource utilization data from patient charts (before and after the index SRE diagnosis). Country-specific unit costs were from 2010 and local currencies were converted to 2010 euros. Results The mean costs across countries were €7043, €5242, €11,101, and €11,509 per radiation to bone, pathologic fracture, surgery to bone, and spinal cord compression event, respectively. Purchasing power parity (PPP)-adjusted mean cost ratios were similar in most countries, with the exception of radiation to bone. Limitations The overall burden of SREs may have been under-estimated owing to home visits and evaluations outside the hospital setting not being reported here. Conclusions All SREs were associated with substantial costs. Variation in SRE-associated costs between countries was most likely driven by differences in treatment practices and unit costs.

Frequency of skeletal-related events and associated healthcare resource use and costs in US patients with multiple myeloma.

OBJECTIVE: A potential complication for all new multiple myeloma (MM) patients is the clinical presentation of osteolytic lesions which increase the risk for skeletal-related events (SREs). However, the contribution of SREs to the overall economic impact of MM is unclear. The impact of SREs on healthcare resource utilization (HCRU) and costs for US patients with MM was analyzed in Truven Health Marketscan Commercial Claims and Medicare Supplemental Databases. METHODS: Adults diagnosed with MM between January 1, 2005 and December 31, 2010 with ≥2 claims ≥30 days apart (first claim = index date) were included. SREs included: hypercalcemia, pathologic fracture, surgery for the prevention and treatment of pathologic fractures or spinal cord compression, and radiation for bone pain. Rates of HCRU (outpatient [OP], inpatient [IP], emergency room [ER], orthopedic consultation [OC], and ancillary) and healthcare costs were compared between MM patients with and without SREs. Inverse propensity weighting was applied to adjust for potential bias. RESULTS: Of 1028 MM patients (mean age = 67, standard deviation = 13.2), 596 patients with ≥1 SRE and 432 without SREs were assessed. HCRU rates in IP, ER, and ancillary (p < 0.01) and mean total costs of OP, IP, and ER were significantly higher (p < 0.05) for patients with vs without SREs during follow-up. HCRU rates also increased with SRE frequency (p < 0.05 in OP, IP, ER, OC, and ancillary), as did mean total healthcare costs, except for OC (p < 0.001). LIMITATIONS: A broad assessment of pharmacotherapy for the treatment of MM was not an objective of the current study. Bisphosphonate use was evaluated; however, results were descriptively focused on frequency of utilization only and were not included in the broader cost and HCRU analysis. CONCLUSIONS: Among US patients with MM, higher SRE frequency was associated with a significant trend of higher HCRU and total healthcare costs in several settings.

Health economic implications of perioperative delirium in older patients after surgery for a fragility hip fracture.

BACKGROUND: Patients who experience a fragility hip fracture are at high risk for perioperative delirium. The purpose of the present study was to evaluate the impact, from a hospital perspective, of perioperative delirium on the length of the hospital stay and episode-of-care costs for elderly patients who underwent surgical treatment of a fragility hip fracture. METHODS: A total of 242 patients sixty-five years of age or older (mean age, eighty-two years; range, sixty-five to 103 years) who underwent surgical treatment of a fragility hip fracture at a single center between January 2011 and December 2012 were evaluated. Demographic, clinical, surgical, and adverse-events data were extracted and analyzed. The confusion assessment method (CAM) was used prospectively to detect perioperative delirium. RESULTS: One hundred and sixteen (48%) of the 242 patients developed perioperative delirium during their stay in the hospital. Compared with patients with no delirium, delirium was associated with a mean incremental total length of hospital stay of 7.4 days (95% confidence interval [CI] = 3.7 to 11.2 days; p < 0.001), a mean incremental length of stay following surgery of 7.4 days (95% CI = 3.8 to 11.1 days; p < 0.001), and a mean incremental episode-of-care cost (in 2012 Canadian dollars) of $8286 (95% CI = $3690 to $12,881; p < 0.001). The total incremental episode-of-care cost attributable to delirium over the study period was $961,131 in 2012 Canadian dollars. CONCLUSIONS: Nearly 50% of elderly patients who underwent surgery for a fragility hip fracture developed perioperative delirium, which was associated with a significant incremental in-hospital length of stay and significant incremental episode-of-care costs. These findings highlight the importance of implementing cost-effective interventions to reduce the prevalence of perioperative delirium in elderly patients with a low-energy hip fracture.

Canadian health care institution resource utilization resulting from skeletal-related events.

PURPOSE: We describe the types of major institution health care resources consumed as a result of skeletal-related events (SREs) [ie, pathological fracture, bone surgery, radiation to bone, spinal cord compression]. METHODS: A retrospective multicenter chart review of cancer patients with bone metastases who experienced SREs was conducted. Patients with multiple SREs occurring during the same hospitalization within 21 days of each other were grouped into SRE clusters. RESULTS: We reviewed 156 patient charts from 4 Canadian institutions, accounting for 358 SREs and 259 SRE clusters. Of the total patients, 63% experienced 1 SRE; 19%, 2 SREs; 10%, 3 SREs; and 8%, ≥ 4 events. Health care resource utilization was captured for ≥ 90 days following each SRE: 54% of all SRE events resulted in an inpatient stay; 34% in an emergency visit; 85% of SREs required the use of diagnostic procedures (including radiography, magnetic resonance imaging, Computerized Axial Tomography scans, and radio scans); 57% required radiation treatment; 34% required a surgical procedure; 35% received outpatient treatment visits (ie, physiotherapy or occupational therapy). Bone surgery and spinal cord compression were more often associated with hospitalization than were other SRE types. Spinal cord compression was associated with the greatest number of inpatients stays (1.09 per SRE), longest duration of hospital stay (mean 26.18 days per SRE), and more outpatient visits, relative to other SRE types. CONCLUSION: Results of our Canadian retrospective study clearly demonstrate that SREs occur in cancer patients and each SRE is associated with considerable institutional consumption of health care resources.

Healthcare costs associated with skeletal-related events in breast cancer patients with bone metastases.

BACKGROUND: Patients with bone metastases secondary to breast cancer are pre-disposed to skeletal-related events (SREs), including spinal cord compression (SCC), pathologic fracture (PF), surgery to bone (SB), and radiotherapy to bone (RT). OBJECTIVE: To document current patterns of healthcare utilization and costs of SREs in patients with breast cancer and bone metastases. METHODS: This was a retrospective, observational study using the Thomson MedStat MarketScan Commercial Claims and Encounters database from 9/2002 to 6/2011. Study subjects included all persons with claims for breast cancer and for bone metastases, and ≥1 claims for an SRE. Unique SRE episodes were identified based on a gap of at least 90 days without an SRE claim, and classified by treatment setting (inpatient or outpatient) and SRE type (SCC, PF, SB, or RT). RESULTS: Of 17,266 patients with breast cancer and bone metastases, 9142 (53%) had one or more SRE episodes. Among 5809 patients who met all other criteria, there were 7617 SRE episodes over mean (SD) follow-up of 17.2 (15.2) months. The percentage of episodes that required inpatient treatment ranged from 11% (RT) to 76% (SB). On average, inpatient SCC episodes (n=83 episodes) were most costly; while outpatient PF episodes (n=552 episodes) were least costly. Of the total SRE costs (mean [SE] $21,072 [$36,462]/episode), 36% were attributable to outpatient RT (n=5265 episodes) and 31% to inpatient PF (n=838 episodes). LIMITATIONS: The administrative claims data used in this study may lack sensitivity and specificity for identification of clinical events and may not be generalizable to other populations. Also, for some SRE episode categories, the number of events was small and cost estimates may lack precision. CONCLUSION: In patients with breast cancer and bone metastases, SREs are associated with high costs and hospitalizations.

Clinical, economic and humanistic burdens of skeletal-related events associated with bone metastases.

Despite effective skeletal-related event (SRE)-limiting therapies such as zoledronic acid and denosumab, SREs continue to place a meaningful burden on patients, providers and payers. However, studies of SRE-related effects on clinical (i.e., survival), economic (i.e., cost per event) and humanistic (i.e., quality of life) outcomes often report results in a composite manner and frequently do not differentiate the effects by SRE-type (i.e., bone radiation, bone surgery, hypercalcemia, pathological fracture and spinal cord compression). Nevertheless, understanding the differential burdens of individual SRE types, which vary in severity and duration of effect, is an important consideration - particularly in pharmacoeconomic evaluations of SRE-limiting therapies. In this review of the clinical, economic and humanistic SRE burden, it was found that SRE types can be differentiated by these outcomes, although economic outcomes are far more frequently reported than clinical or humanistic.

The economic burden associated with skeletal-related events in patients with bone metastases secondary to solid tumors in Belgium.

OBJECTIVES: More than 1.5 million patients worldwide are affected by bone metastases. Patients with bone metastases frequently develop skeletal-related events (SREs, including radiation to bone, non-vertebral fracture, vertebral fracture, surgery to bone, and spinal cord compression) that are associated with high healthcare costs. This study aims to provide an estimate of the cost per SRE in both the inpatient and outpatient settings in Belgian patients with bone metastases secondary to solid tumors (breast, prostate, and lung cancers). METHODS: Patients were retrieved from the IMS Hospital Disease database from 2005-2007. Inclusion was based on the International Classification of Diseases and Related Health Problems Version 9 (ICD-9) diagnosis and/or procedure codes covering patients with breast, prostate, or lung cancer with bone metastases who were hospitalized for one or more SREs. All costs were extrapolated to 2010 using progression in hospitalization costs since 2001. Additional outpatient costs resulting from radiation to bone and diagnostic tests performed in ambulatory settings were estimated by combining published unit costs with resource use data obtained from a Delphi panel. RESULTS: The average cost per SRE across solid tumor types based on the weighted average of inpatient and outpatient costs was €2653 for radiation to bone, €5015 for a vertebral fracture, and €7087 for a non-vertebral fracture. Costs were €12,885 and €15,267 for surgery to bone and spinal cord compression, respectively. LIMITATIONS: No patient follow-up across calendar years could be done. Also, details regarding the exact anatomic sites of SREs were not always available. CONCLUSIONS: SREs add a substantial cost to the management of patients with bone metastases. Avoiding SREs can lead to important cost-savings for the healthcare payer.

Comparison of plain vertebral X-ray and dual-energy X-ray absorptiometry for the identification of older women for fracture prevention in primary care.

BACKGROUND: Recently, the dual-energy X-ray absorptiometry (DXA) diagnostic cut-off (T-score) for Australian Pharmaceutical Benefits Scheme (PBS) supported primary fracture prevention therapy with alendronate for older women (>70 years) has been changed from -3.0 to -2.5. AIM: To examine the impact of the expanded criteria for PBS-supported fracture prevention therapy in older women on case finding and cost. METHODS: One thousand, nine hundred and eighty-three women, median age 76 years, not previously known to have low bone mineral density by DXA or a vertebral fracture underwent DXA scanning and a thoracolumbar X-ray. A woman was considered eligible for fracture prevention therapy if she had a T-score ≤-2.5 at the femoral neck and/or the lumbar vertebrae (two to four) or at least one vertebral fracture of ≥20% deformity. RESULTS: Seven hundred and forty-six women (37.6%) met the new criteria as a case for PBS-subsidised fracture prevention therapy. Four hundred and thirty-one (21.7%) had a T-score ≤-2.5 on DXA compared with 10.6% (n = 210) with a T-score ≤-3.0. Four hundred and eighty-three (24.4%) had at least one vertebral fracture. Only 8.5% (n = 168) had both a T-score ≤-2.5 and a prevalent vertebral fracture. The cost per case found by DXA equated to $460 compared with $398 for screening by thoracolumbar X-ray. CONCLUSIONS: The use of either DXA or X-ray will identify approximately two-thirds of women aged 70 years and over who would be eligible for fracture prevention. The use of X-ray would identify a marginally larger number of women and at lower financial cost but involve substantially greater radiation exposure.

[Estimate of the 10-year risk of osteoporotic fractures in the Spanish population]. / Estimación del riesgo de fractura osteoporótica a los 10 años para la población española.

BACKGROUND AND OBJECTIVE: The QFRACTURE(®) tool allows to estimate the risk of osteoporotic fractures in 10 years. We have estimated it, both for major and hip fracture, from the data obtained from the National Health Questionnaire. We thus estimated the risk of fragility fractures in the next 10 years in the Spanish population of both genders and calculated its burden. SUBJECTS AND METHODS: We have used the QFRACTURE(®) tool which estimates the risk of any fracture and hip fracture in the next 10 years. RESULTS: A total of 552.879 women and 161.922 men will suffer a fragility fracture in the next 10 years in Spain. Most of the fractures will happen in people aged 70 years old and more. In 10 years there will be 263.351 hip fractures in women and 84.213 in men. More than half of the hip fractures in women will happen to those aged more than 77 years old. The burden of osteoporotic fractures in Spain could arise to 4.778 millions of euros in the next 10 years with a cut-off of 3% for hip fracture accepting as reference the cost of generic alendronate. CONCLUSIONS: We have a first approach to the number of osteoporotic fractures in the next 10 years and its burden. The knowledge of this figures may be useful in order to program strategies to reduce the number of osteoporotic fractures in the future.

Two-year cost comparison of vertebroplasty and kyphoplasty for the treatment of vertebral compression fractures: are initial surgical costs misleading?

UNLABELLED: The costs for treating kypho- and vertebroplasty patients were evaluated at up to 2 years postsurgery. There were no significant differences in adjusted costs in the first 9 months postsurgery, but kyphoplasty patients were associated with significantly lower adjusted treatment costs by 6.8-7.9% in the remaining periods through 2 years postsurgery. INTRODUCTION: Vertebral augmentation has been shown to be safe and effective for treating vertebral compression fractures. Comparative cost studies of initial treatment costs for kypho- and vertebroplasty have been mixed. The purpose of our study was to compare the costs for treating kypho- and vertebroplasty patients at up to 2 years postsurgery. METHODS: Vertebroplasty and kyphoplasty patients diagnosed with pathologic or closed lumbar/thoracic vertebral fractures were identified from the 5% sample of the Medicare dataset (2006-2009). The final study cohort with at least 2 years follow-up comprised of 1,609 vertebroplasty and 2,878 kyphoplasty patients. The cumulative treatment costs (adjusted to June 2011 US$) were determined from the payer perspective. Differences in costs and length of stay were assessed by generalized linear mixed model regression, adjusting for covariates. RESULTS: The average adjusted costs for vertebroplasty patients within the first quarter and the first 2 years postsurgery were $14,585 [95% confidence interval (CI), $14,109-15,078] and $44,496 (95% CI, $42,763-46,299), respectively. The corresponding average adjusted costs for kyphoplasty patients were $15,117 (95% CI, $14,752-15,491) and $41,339 (95% CI, $40,154-42,560). There were no significant differences in adjusted costs in the first 9 months postsurgery, but kyphoplasty patients were associated with significantly lower adjusted treatment costs by 6.8-7.9% in the remaining periods through 2 years postsurgery. CONCLUSION: Our present study addresses some of the limitations in previous comparative cost studies of vertebroplasty and kyphoplasty. The higher adjusted costs for vertebroplasty patients than kyphoplasty patients by 1 year following the surgery reflect greater utilization of medical resources.

How rebates, copayments, and administration costs affect the cost-effectiveness of osteoporosis therapies.

PURPOSE: Because of rising drug expenditures, cost considerations have become essential, necessitating the requirement for cost-effectiveness analyses for managed care organizations (MCOs). The study objective is to examine the impact of various drug-cost components, in addition to wholesale acquisition cost (WAC), on the cost-effectiveness of osteoporosis therapies. DESIGN: A Markov model of osteoporosis was used to exemplify different drug cost scenarios. METHODOLOGY: We examined the effect of varying rebates for oral bisphosphonates--risedronate and ibandronate--as well as considering the impact of varying copayments and administration costs for intravenous zoledronate. The population modeled was 1,000 American women, > or = 50 years with osteoporosis. Patients were followed for 1 year to reflect an annual budget review of formularies by MCOs. The cost of therapy was based on an adjusted WAC, and is referred to as net drug cost. The total annual cost incurred by an MCO for each drug regimen was calculated using the net drug cost and fracture cost. We estimated cost on a quality adjusted life year (QALY) basis. PRINCIPAL FINDINGS: When considering different rebates, results for risedronate versus ibandronate vary from cost-savings (i.e., costs less and more effective) to approximately $70,000 per QALY. With no risedronate rebate, an ibandronate rebate of approximately 65% is required before cost per QALY surpasses $50,000. With rebates greater than 25% for risedronate, irrespective of ibandronate rebates, results become cost-saving. Results also showed the magnitude of cost savings to the MCO varied by as much as 65% when considering no administration cost and the highest coinsurance rate for zoledronate. CONCLUSION: Our study showed that cost-effectiveness varies considerably when factors in addition to the WAC are considered. This paper provides recommendations for pharmaceutical manufacturers and MCOs when developing and interpreting such analyses.

Percutaneous vertebroplasty and kyphoplasty for pathologic vertebral fractures in the Medicare population: safer and less expensive than open surgery.

PURPOSE: To compare cost and outcomes of surgical and percutaneous treatments of pathologic vertebral fractures. MATERIALS AND METHODS: Standard Medicare 5% anonymized inpatient files (1999-2009) were retrospectively reviewed. Patients with a diagnosis of vertebral fracture without spinal cord injury and primary or metastatic bony malignancy were divided into percutaneous or surgical groups based on whether they received vertebroplasty/kyphoplasty or surgical treatment. Patients who had no intervention or both interventions were excluded. Cost, length of stay, and type of discharge were examined while controlling for demographic and comorbidity variables. RESULTS: A total of 451 patients were included; 52% received percutaneous treatment and 48% received surgery. Patients treated percutaneously were older (P < .001) and more likely to be female (P = .04). Percutaneous therapy predicted $14,862 less Medicare cost and $13,565 less overall cost (P < .001 for both), and 4.1 fewer inpatient days (P < .001). Patients who underwent surgery had higher odds of death (odds ratio = 3.38, P = .016), discharge to a rehabilitation facility (odds ratio = 3.3, P = .003), and transfer to another inpatient facility (odds ratio = 8.53, P < .001), and lower odds of discharge to home (odds ratio = 0.42, P < .001) and hospice (odds ratio = 0.08, P = .002). CONCLUSIONS: In a Medicare population with bony malignancy and vertebral fractures, percutaneous therapy predicted significantly reduced cost and length of stay versus surgery. Patients who underwent percutaneous therapy were significantly less likely to die, be transferred, or be discharged to rehabilitation facilities, and were more likely to be discharged to home or hospice.

Metastatic disease of the long bones: a review of the health care burden in a major trauma centre.

BACKGROUND: More than 140,000 new cases of cancer are diagnosed annually in Canada, nearly half of which metastasize to bone. The implications for orthopedic oncology services are potentially huge. We reviewed the experience in a major Canadian orthopedic trauma centre treating long bone metastases. The primary aim was to quantify the caseload, and the secondary aim was to report on the methods of fixation. METHODS: We conducted a retrospective review of all patients treated for pathologic lesions or fracture secondary to metastatic disease over a 20-year period from July 1987 to March 2007. RESULTS: The mean number of cases treated annually was 13. Most patients came from the local oncology centre. The median length of stay in hospital was 11 days. In-hospital mortality was 14%. The fatal pulmonary embolus rate was 5% for femoral lesions. The revision rate for the operative intervention was 3%. CONCLUSION: The caseload was much lower than anticipated, likely owing to under-referring from oncology services. The high mortality rate may reflect delay in seeking orthopedic opinion, but overall the fixation methods appeared durable.

What is the role of the orthopaedic surgeon in management of fragility fractures?

Fragility fractures are the most prevalent trauma condition that orthopaedic surgeons face today. Osteoporosis and susceptibility to falls are the key predisposing factors. Despite evidence supporting the impact of treating osteoporosis on reducing the incidence of fragility fractures, it is often left untreated. Orthopaedic surgeons are often the first physicians to assess and treat the patient after a fragility fracture. Their role therefore does not end in the skillful fixation of the fractures, but they have a unique opportunity to ensure that preventive measures are implemented. This includes falls prevention, investigation of possible causes underlying osteoporosis, attention to diet, exercise, calcium, and vitamin D supplementation as well as prescription of anti-resorptive and anabolic medication. The need for a dedicated multidisciplinary team needs to be emphasized and therefore effective communication between the different parties is of paramount importance.

The societal burden of osteoporosis.

Osteoporosis currently affects 10 million Americans and is responsible for more than 1.5 million fractures annually. The financial burden of osteoporosis is substantial, with annual direct medical costs estimated at 17 to 20 billion dollars. Most of these costs are related to the acute and rehabilitative care following osteoporotic fractures, particularly hip fractures. The societal burden of osteoporosis includes these direct medical costs and the monetary (eg, caregiver time) and nonmonetary costs of poor health. The aging of the US population is expected to increase the prevalence of osteoporosis and the number of osteoporotic fractures. Growth of the older adult population will pose significant challenges to Medicare and Medicaid, which bear most of the cost of osteoporosis. Efforts to address the looming financial burden must focus on reducing the prevalence of osteoporosis and the incidence of costly fragility fractures.

The hospital burden of disease associated with bone metastases and skeletal-related events in patients with breast cancer, lung cancer, or prostate cancer in Spain.

Metastatic bone disease (MBD) is the most common cause of cancer pain and of serious skeletal-related events (SREs) reducing quality of life. Management of MBD involves a multimodal approach aimed at delaying the first SRE and reducing subsequent SREs. The objective of the study was to characterise the hospital burden of disease associated with MBD and SREs following breast, lung and prostate cancer in Spain. Patients admitted into a participating hospital, between 1 January 2003 and 31 December 2003, with one of the required cancers were identified and selected for inclusion into the study. The index admission to hospital, incidence of patients admitted and hospital length of stay were analysed. There were 28,162 patients identified with breast, lung and prostate cancer. The 3 year incidence rates of hospital admission due to MBD were 95 per 1000 for breast cancer, 156 per 1000 for lung cancer and 163 per 1000 for prostate cancer. For patients admitted following an SRE, the incidence rates were 211 per 1000 for breast cancer, 260 per 1000 for lung cancer and 150 per 1000 for prostate cancer. This study has shown that cancer patients consume progressively more hospital resources as MBD and subsequent SREs develop.

[Kyphoplasty in osteoporotic spinal fractures]. / Kyphoplastie bei osteoporotischen Wirbelfrakturen.

Kyphoplasty has been the standard procedure for osteoporotic fractures for more than 5 years but the material costs are still very high. The aim of this study was to clarify whether pain reduction could be achieved without increasing the rate of new fractures and also in what areas costs could possibly be reduced. From 15.01.2007 until 15.01.2008, a total of 100 patients with 126 recent osteoporotic spinal fractures were treated by kyphoplasty with an average operation time of 38 min and follow-up times up to 12 months. During this follow-up period 15 lateral and 2 dorsal cement leakages remained asymptomatic and 1 dorsal leakage caused an incomplete paraparesis, which was finally cured completely. All patients were very content and pain measured on the visual analogous scale could be lowered from 8.0 before the operation to 2.7 points after the operation. With material costs of 3,056 Euro, there were additional operation costs of 247 Euro per case. The average effective weight was 2.84. On average 7,810 Euro returns could be achieved, deducting material and operation costs left 4,507 Euro per case. More than 40% of gains were reinvested in operation and material costs. Within 12 months 6 new fractures occurred despite medicinal prophylactic treatment which could also be successfully treated by kyphoplasty. The average visual analogous scale after 12 months was 2.1 points.Kyphoplasty still causes financial deficits due to high material costs, however, patients benefit from a reduction of pain.

Cost-effectiveness model of using zoledronic acid once a year versus current treatment strategies in postmenopausal osteoporosis.

OBJECTIVES: To compare effectiveness, associated cost of outcomes and cost-effectiveness of a single annual infusion of zoledronic acid versus current treatment strategies plans for postmenopausal osteoporosis in France. METHODS: Twelve simulation-based models were built to investigate three types of fractures: vertebral (VF), non-vertebral excluding hip (NVF) and hip (HF), comparing two groups: zoledronic acid and current postmenopausal antiosteoporotic treatment strategies. Two effectiveness comparability assumptions have been tested: specific agent efficacy values, and same standard efficacy values for all active agents. Direct medical costs included drug costs, medical visits, monitoring and fracture management. Adherence levels were integrated into the model under the assumption that non-adherent patients had treatment effects similar to the levels of placebo effectiveness. RESULTS: Using the most conservative assumption (same standard efficacy values for all active agents), zoledronic acid strategy results in less vertebral, non-vertebral and hip fractures than other current antiosteoporotic treatment options over 3 years: 12.04% vs. 14.18%, 10.61% vs. 11.28% and 2.82% vs. 4.64% respectively, (p<0.001). In addition, zoledronic acid is more cost-effective than the current treatment strategies in all types of fractures (p<0.001): 1497 euros vs. 1685 euros per VF avoided, 1337 euros vs. 1404 euros per NVF avoided and 1216 euros vs. 1323 euros per HF avoided. CONCLUSION: Zoledronic acid is a cost-effective treatment strategy regardless of fracture type or effectiveness comparability assumptions.
