Geographic disparities in access to cancer care: do patients in outlying areas talk about their access problems to their general practitioners and medical oncologists and how does that impact on the choice of chemotherapy?

Geographic disparities in access to cancer care have been reported for several countries. The distance between the place of residence and the cancer care centre can be one cause of these disparities. Solutions to surmount the barriers can be found if patients talk about this to their care professionals. We investigated whether patients in Valais talk with their physicians about difficulties to access cancer care. We interviewed five general practitioners and five medical oncologists in Valais with semi-structured interviews to identify difficulties patients are talking about. Medical oncologists were also interviewed on their habits to adapt chemotherapy to access problems of their patients. Cancer patients in Valais do talk about their access problems. Medical oncologists in Valais do take access problems into account when discussing therapeutic options with the patients and use the scope they have within their therapeutic options. In Valais the family of cancer patients play an important role in access to cancer care. Special offers are in place when social support is insufficient. Whether some socio-economic minorities do not use the solutions in place cannot be answered and should be investigated in further studies.

Potential health economic impact of intravenous iron supplementation to erythropoiesis-stimulating agent treatment in patients with cancer- or chemotherapy-induced anemia.

BACKGROUND: Intravenous (i.v.) iron supplementation significantly improves the response to erythropoiesis-stimulating agent (ESA)-based therapies in patients with cancer- or chemotherapy-induced anemia. The economic implications of adding i.v. iron to ESA treatment are less well investigated. Published randomized controlled trials do not provide sufficient data for a comprehensive cost-effectiveness analysis. METHODS: Preliminary cost calculations from the Swiss health care system perspective based on a meta-analysis and published results of eight randomized controlled trials without correction for decreased ESA need provide a conservative cost-effectiveness estimate. RESULTS: The additional total cost of i.v. iron supplementation ranged from EUR 417 to EUR 901 per patient depending on the evaluated iron-carbohydrate complex. Considering a 24% absolute increase in the proportion of ESA responders, the incremental cost-effectiveness ratios per additional responder are EUR 1,704-3,686. In routine practice, better values may be achieved due to ESA dose savings. CONCLUSION: Supplementation of ESAs with i.v. iron appears to be an economically viable treatment option in anemic cancer patients. Additional research on ESA dose savings and cost-effectiveness is required.

Addition of cetuximab to first-line chemotherapy in patients with advanced non-small-cell lung cancer: a cost-utility analysis.

BACKGROUND: Adding cetuximab to standard chemotherapy results in a moderate increase of overall survival in patients with advanced non-small-cell lung cancer (NSCLC), but the cost-effectiveness is unknown. MATERIALS AND METHODS: A Markov model was constructed based on the results of the First-Line ErbituX in lung cancer randomized trial, adding cetuximab to cisplatin-vinorelbine first-line chemotherapy in patients with advanced NSCLC. The primary outcome was the incremental cost-effectiveness ratio (ICER) of adding cetuximab, expressed as cost per quality-adjusted life year (QALY) gained, and relative to a willingness-to-pay threshold of €60 000/QALY. The impact of cetuximab intermittent dosing schedules on the ICER was also evaluated. RESULTS: Adding cetuximab to standard chemotherapy leads to a gain of 0.07 QALYs per patient at an additional cost of €26 088. The ICER for adding cetuximab to chemotherapy was €376 205 per QALY gained. Intermittent cetuximab dosing schedules resulted in ICERs per QALY gained between €31 300 and €83 100, under the assumption of equal efficacy. CONCLUSIONS: From a health economic perspective, the addition of cetuximab to standard first-line chemotherapy in patients with epidermal growth factor receptor-expressing advanced NSCLC cannot be recommended to date, due to a high ICER compared with other health care interventions. Treatment schedules resulting in more favorable cost-utility ratios should be evaluated.

Trastuzumab beyond progression: a cost-utility analysis.

BACKGROUND: The continuation of trastuzumab beyond progression in combination with capecitabine as secondary chemotherapy for HER2-positive metastatic breast cancer (MBC) prolongs progression-free survival without a substantial increase in toxicity. PATIENTS AND METHODS: A Markov cohort simulation was used to follow the clinical course of typical patients with MBC. Information on response rates and major adverse effects was derived, and transition probabilities were estimated, based on the results of the Breast International Group 03-05 clinical trial. Direct costs were assessed from the perspective of the Swiss health care system. RESULTS: The addition of trastuzumab to capecitabine is estimated to cost on average an additional of €33,980 and to yield a gain of 0.35 quality-adjusted life years (QALYs), resulting in an incremental cost-effectiveness ratio of €98,329/QALYs gained. Probabilistic sensitivity analysis showed that the willingness-to-pay threshold of €60,000/QALY was reached in 12% of cases. CONCLUSION: The addition of trastuzumab to capecitabine in MBC patients is more expensive than what is typically regarded as cost-effective but falls within the value ranges found for established regimens in the treatment of MBC.

Cost-effectiveness of antihypertensive treatment in patients 80 years of age or older in Switzerland: an analysis of the HYVET study from a Swiss perspective.

This analysis shows the economic benefit of antihypertensive treatment in patients 80 years of age or older from the perspective of the Swiss healthcare system. The cost-effectiveness analysis of antihypertensive treatment in the elderly was carried out applying the results of the Hypertension in the Very Elderly Trial study to the Swiss healthcare system. The analysis shows that hypertension treatment provides, compared with placebo, an additional life expectancy of 0.0457 years per patient, over a follow-up period of 2 years. The medication cost was covered by the reduction of costs related to the treatment of strokes, myocardial infarctions and heart failure: the total cost per patient in the active group resulted in a dominant strategy of savings compared with the placebo group. Sensitivity analysis yielded a stable estimate after varying the costs of medication, stroke, myocardial infarction, heart failure and life expectancy, confirming the robustness of these results. Moreover, considering that antihypertensive treatment also positively affects the incidence of dementia, those net benefits might even be underestimated.

Cost-effectiveness of raltegravir in antiretroviral treatment-experienced HIV-1-infected patients in Switzerland.

OBJECTIVES: Raltegravir, a novel integrase inhibitor, has shown great efficacy in reducing HIV viral load among treatment-experienced patients. A cohort state-transition model was used to assess the long-term effect of raltegravir treatment on costs and quality-adjusted life expectancy from a Swiss perspective. METHODS: Patients were stratified into health states according to opportunistic infection status, HIV RNA level, and CD4 count, with each group assigned a treatment cost and utility (quality of life) score. Model inputs came from published studies, clinical trials, and database analyses. Results were used to calculate incremental cost-effectiveness ratio (ICER) of raltegravir use, expressed in Swiss francs (CHF) as incremental cost/quality-adjusted life-year (QALY) gained. Future costs and QALYs were discounted at 3% per year. RESULTS: Five years of raltegravir treatment increased discounted quality-adjusted life expectancy by 3.73 years over placebo, with additional discounted cost of CHF 170,347, resulting in an ICER of CHF 45,687/QALY. ICERs ranged from CHF 42,751 to 53,478/QALY for treatment duration of 3 and 10 years, respectively. Results were most sensitive to changes in raltegravir treatment duration, source of estimated quality of life weights, and raltegravir price. CONCLUSIONS: Adding raltegravir to optimized background therapy was a cost-effective strategy for treatment-experienced patients in Switzerland.

Reducing the burden of influenza-associated complications with antiviral therapy.

INTRODUCTION: Influenza imposes an annual burden on individuals, society, and healthcare systems. This burden is increased by the development of complications that are often more severe than the primary infection. Here, we examine the main complications associated with influenza and review the effectiveness of antiviral therapy in reducing the incidence of such events. MATERIAL AND METHODS: The content of this review is taken from the study of the authors' extensive collection of reference materials, examination of the bibliographical content of relevant papers, and the results of Medline searches. RESULTS: The most commonly encountered complications in adults are sinusitis, pharyngitis, bronchitis, and, particularly in the elderly, bacterial pneumonia. Such complications may exacerbate pulmonary complaints. Children are particularly prone to post-influenza croup and otitis media. Complications involving the central nervous system, heart, or skeletal muscle also occur in influenza patients. Influenza-associated complications impose sizeable healthcare costs in terms of outpatient contacts, hospitalizations, and antibiotic use. Vaccination is the primary prevention strategy for influenza and its complications, but has limitations. Neuraminidase inhibitors have demonstrated efficacy in reducing the incidence of influenza-associated complications in populations with different ages and risks. CONCLUSIONS: Influenza complications place a large burden on healthcare providers and society. Neuraminidase inhibitors can reduce the incidence of such complications, particularly in high-risk groups.

[Evolution of influenza vaccination coverage in France from 2001 to 2006]. / Evolution du taux de couverture vaccinale contre la grippe en France : de 2001 à 2006.

INTRODUCTION: The increased risk of a new influenza pandemic has raised awareness of the need for high influenza vaccination rates. OBJECTIVES: This study aims at assessing trends in influenza vaccination coverage from 2001 to 2006 in France, at understanding the drivers and barriers, and to identify vaccination intentions for 2006/2007. METHODS: We conducted a mail-based household survey on 9,835 persons representative of the population from age 15. Essentially, the same questionnaire was used in all seasons. RESULTS: The influenza vaccination coverage rate slightly increased, reaching 24.2% in 2005/2006 (70.1% in patients over 65). In the last two seasons the fact that the vaccination was provided for free was the most frequent reason for getting vaccinated. Older age, considering influenza as a serious disease and recommendations from the family doctor or nurse were also important drivers for vaccination. Only 2% of those vaccinated in 2005/2006 indicated the threat of avian influenza as a reason. The reasons for non-vaccination among persons never vaccinated before were feeling too young for vaccination, never having considered vaccination before and absence of recommendation by the family doctor. Among those who were previously vaccinated but not in the current season, the reasons for not being vaccinated were not finding vaccination necessary, forgetfulness and having influenza-like illness despite vaccination. CONCLUSION: Stable vaccination rates were observed from 2001 to 2006. France is well on its way to reach the international vaccination goal set by the WHO (75% in the elderly population), but continuously effort is needed for others.

Cost-effectiveness of trastuzumab in the adjuvant treatment of early breast cancer: a model-based analysis of the HERA and FinHer trial.

BACKGROUND: Routine adjuvant administration of trastuzumab (T) has been implemented in most centers, but its economic impact has not yet been well examined. METHODS: A Markov model was constructed based on clinical data of the Herceptin Adjuvant (HERA) and the Finland Herceptin (FinHer) trials. Costs from the perspective of a Swiss health care provider were calculated based on resource use. RESULTS: On the basis of HERA data, our model yielded an overall survival rate of 71.8% for the T group versus 62.8% for the control group [risk ratio (RR) = 0.87) after 10 years and 62.9% versus 52.7% (RR = 0.84) after 15 years. Cost-effectiveness resulted in 40505 Euros (EUR) per life years gained (LYG) after 10 years and 19673 EUR per LYG after 15 years. For the FinHer regimen, overall survival after 10 and 15 years resulted in 81.8% versus 66.1% (RR = 0.81) and 73.6% versus 57.0% (RR = 0.77). Costs of 8497 EUR per patient could be saved after 10 years and 9256 EUR after 15 years compared with the control group. CONCLUSION: In a long-term perspective, adjuvant T based on the HERA regimen can be considered cost-effective. The regimen used in the FinHer trial is even cost saving, but estimations are based on a single small trial.

Pharmacoeconomics of anticoagulation therapy for stroke prevention in atrial fibrillation: a review.

INTRODUCTION: Atrial fibrillation (AF) increases the risk of ischemic stroke 5-fold and may not only be responsible for as many as 15% of all strokes that occur but also for larger and more disabling strokes than those attributable to other causes which increase the associated costs of care. Anticoagulation with warfarin in the target INR of 2.5 is a major clinical challenge in real-life practice, given that the complex relationship between warfarin dosage and response is readily altered by a variety of factors such as concurrent medications, illnesses, genetic influences, and dietary/lifestyle changes. Consequently, INR values are out of the target range approximately half of the time in real-life studies compared to clinical trial setting. Current anticoagulation therapies are less likely to be cost-effective in routine clinical practice and need improvement. The aim of this review is to discuss the pharmacoeconomic consequences of this management strategy by analysing the optimal treatment option within specific age and risk groups, confirming current guidelines for a health economic perspective and considering the economic impact on health care policy. METHODS: An electronic search of the Medline/PubMed database from 1966 to 2005 was performed to identify articles dealing with all pharmacoeconomic aspects of stroke prevention in atrial fibrillation. The following search terms were used: 'atrial fibrillation', 'stroke', 'cost', 'warfarin'. RESULTS: Treatment with warfarin is cost-effective (versus aspirin or no therapy) in patients with AF at moderate-to-high risk of stroke. The cost-effectiveness of anticoagulation therapy is driven by the achieved risk reduction rather than the potential benefits estimated from clinical trials. Failure to maintain optimal anticoagulation places patients at risk of complications, the management of which is a significant cost driver. CONCLUSION: Improvement could be achieved by optimising physicians and patient's knowledge driven through prevention campaigns by health care policy.

[Long-term treatment of patients with symptomatic gastroesophageal reflux disease comparing costs and efficacy over 6 months of treatment with Nexium On-Demand Treatment or Nexium continuous treatment. An open, randomised multi-center study]. / Wirksamkeit und Kosten einer kontinuierlichen Langzeit- behandlung mit Esomeprazol versus einer Anwendung bei Bedarf bei symptomatischen Reflux-Patienten in der Praxis ohne endoskopische Abklärung-die ONE Studie (On-demand Nexium Evaluation).

This open, randomized study (ONE: On-demand Nexium Evaluation) compared the two long-term management options with esomeprazole 20 mg--continuous daily or on-demand treatment--in endoscopically uninvestigated patients seeking primary care for symptoms suggestive of gastroesophageal reflux disease (GERD) who demonstrated complete relief of symptoms after four weeks of initial treatment with esomeprazole 40 mg. In total 1904 patients were randomized. During 26 weeks 913 patients received continuous daily therapy with esomeprazole 20 mg, once daily, while 991 patients were treated with esomeprazole 20 mg on-demand. The continuous therapy offered slightly better relief of the symptom heartburn, however esomeprazole 20 mg taken on-demand was associated with lower direct medical costs. Esomeprazole was generally well tolerated.

[On the prognosis of hip fractures. Assessment of mortality after hip fractures by analyzing overlapping segments of longitudinal data]. / Zur Prognose der Schenkelhalsfraktur. Beurteilung der Mortalität nach Schenkelhalsfraktur durch sektorübergreifende Datenzusammenführung.

BACKGROUND: Data on the treatment of hip fractures in acute care settings have been collected in a report card system for quality assurance in Germany since the beginning of the 1990s. However, there are no data on the long-term outcome and long-term quality of care. MATERIAL AND METHOD: In a retrospective study, data on 1393 patients from 1999 were collected from different sources: from the department of quality assurance at the medical association of Westfalia-Lippe, the Statutory Health Insurance Funds (AOK), and the Medical Review Board of the Statutory Health Insurance Funds (Medizinischer Dienst der Krankenkasse, MDK). Statistical analyses were performed by the Center for Clinical Studies of the University of Düsseldorf. RESULTS: Uni- and multivariate analyses reveal the following prognostic parameters for survival after hip fracture: sex, age, nursing care dependency, living in a nursing home, risk stratification according to ASA, and postoperative complications. Timing of the operation had no affect on survival. CONCLUSIONS: Prognostic factors for the outcome after hip fracture can only be obtained by analyzing data from the hospital stay and the post-hospital setting as well. Chances of survival can be significantly improved by rehabilitative care.

Costs of treatment of Swiss patients with HIV on antiretroviral therapy in hospital-based and general practice-based care: a prospective cohort study.

Some ambulant people with HIV are cared for primarily by their general practitioner and some in an outpatient clinic. Costs and patterns of care in these settings were studied in 65 such patients based in Zürich, from a limited societal perspective (excluding patient costs) based on medical resource use. Antiretroviral therapy (ART), other medications and patient variables were collected prospectively, and non-medication resources (professional time and investigations) and treatment history data were collected from medical records and by record linkage to the Swiss HIV Cohort Study database. Cost differences between the settings were estimated using multiple regression, controlling for differences in case-mix. ART comprised 80% of the total cost, non-medication costs 15% and non-ART medications 5%. Total costs were higher in the outpatient clinic (estimated additional cost after controlling for case-mix = 3489 Swiss Francs per year at 1999 prices, 95% confidence interval 742 to 6236, p=0.017). The difference was accounted for by higher ART costs in the outpatient clinic, not through a tendency to use more expensive drugs or higher doses but rather through the use of more drugs concurrently. Differences in ART prescribing patterns between the doctors in the outpatient clinic and the general practitioners were considerable and appear worthy of further investigation.

[Cost-effectiveness of atorvastatin for the prevention of coronary disease. An analysis of the ASCOT study]. / Kosteneffektivität von Atorvastatin zur Prävention der koronaren Herzkrankheit. Eine Analyse der ASCOT Studie.

BACKGROUND: Increasing health service expenditure, on the one hand, and the politically declared objective of stability of statutory contributions and restriction of public funds, on the other hand, have been central points in the political and social discussion for several years. PATIENTS AND METHODS: Cost-effectiveness of Atorvastatin in primary prevention was analysed by applying the results of the Anglo Scandinavian Cardiac Outcomes Trial (ASCOT study) to the German health system. Costs and effectiveness were subject to an extensive sensitivity analysis. RESULTS: The cost-effectiveness of Atorvastatin treatment in Germany is approximately 10,102 Euro (95% CI: 9109; 12,881) per life-year gained. Taking 2004 price reductions into consideration, these values are reduced to 7311 Euro [95% CI: 5197; 10,091) per life-year gained. The robustness of this result was substantiated through extensive sensitivity analyses. CONCLUSION: The administration of the lipid lowering compound Atorvastatin in hypertensive patients with additional coronary heart disease risk factors in Germany is cost-effective.

Comparison of resource utilization and long-term quality-of-life outcomes between laparoscopic and conventional colorectal surgery.

BACKGROUND: The outcomes of laparosopic and conventional colorectal surgery, with special reference to costs of treatment and patients' quality of life, were compared. METHODS: A partly retrospective cohort study was designed to assess the use of resources, and a follow-up interview was undertaken to evaluate patients' quality of life after both to define laparoscopic (LAP) and conventional (CON) surgery. RESULTS: The length of hospital stay was significantly lower in the LAP group (median, 11 days; interquartile range [IQR], 9-15) than in the CON group (median, 16 days; IQR, 13-23; p < 0.0001), which is reflected in lower costs of hospitalization calculated for the three most frequent surgical interventions. Statistically significant improvements were noted between the median scores in the domains of physical functioning (LAP 85 vs CON 68; p < 0.05) and vitality (LAP 85 vs CON 69; p < 0.05). CONCLUSION: Laparoscopy is a promising alternative for the treatment of patients with colorectal diseases, offering lower costs and a better quality of life in the long term.

Cost-effectiveness studies in ovarian cancer.

Ovarian cancer is the fifth leading cause of cancer-related deaths. The costs associated with this cancer impact both on the affected individual and on the health system. Screening is currently unproven as a strategy for improving outcomes for women with ovarian cancer. Randomized controlled trials, however, are underway, estimating any impact of screening with ultrasound and CA125 on ovarian cancer mortality. Paclitaxel and carboplatin combination, the standard first-line chemotherapy regimen for ovarian cancer, has not been compared with cisplatin and cyclophosphamide regarding the cost-effectiveness and cost-utility, but for paclitaxel and cisplatin, numerous studies have addressed these issues. The estimated incremental costs resulting from these studies fall well within the generally accepted range for new therapies. Although acquisition costs of new chemotherapy drugs exceed those of older drugs, the impact of costly drugs on total costs may be cost saving due to less costs related to supportive and palliative care. The most important costs for the patient, the pain and suffering associated with ovarian cancer and its treatment, are hard to quantify. Nevertheless, patients' quality of life must be considered when making a clinical decision to treat this disease. A review of available cost-effectiveness studies is presented and discussed.

Invasive meningococcal and pneumococcal disease in Switzerland: cost-utility analysis of different vaccine strategies.

We performed a cost-utility analysis for various vaccination strategies against meningococcal and pneumococcal diseases (MenC or MenC/PCV-9) in Switzerland. The analysis compared the current recommendations of vaccinating only children with medical risks to the introduction of the vaccination with either the MenC or the MenC/PCV-9 vaccine, administered at 12 or 2, 4 and 6 months of age, into the existing immunisation programme. For a birth cohort of 80,000 children and assuming a vaccine coverage of 80%, the introduction of a generalised vaccination would be cost-effective. The strategy using three doses of MenC/PCV-9 would achieve the highest health benefit, with 440 quality-adjusted life years (QALYs) gained at costs of 34,000 per QALY.

[Costs and cost-effectiveness of Eptifibatide in the treatment of coronary ischemic syndromes. An analysis based on the PURSUIT study]. / Kosten und Kosteneffektivität von Eptifibatid in der Behandlung des akuten Koronarsyndroms. Eine Analyse auf Basis der PURSUIT-Studie.

AIMS: We analyzed whether using Eptifibatide plus heparin compared to heparin alone in patients with acute coronary ischemic syndromes is cost saving and/or cost-effective from the perspective of German hospitals. Our analysis is based on the clinical results of the PURSUIT study. MATERIALS AND METHODS: We conducted an incremental cost-consequence and cost-effectiveness analysis from the perspective of the admitting hospital. Costs refer to the initial hospitalization following the event. Incremental drug costs are based on a 72 hour infusion of Eptifibatide. Additional costs are analyzed as resulting from the management of complicating myocardial infarctions, including incremental days on the general ward or intensive care unit as well as necessary revascularization procedures. All costs are expressed in EURO (EUR). The estimated costs of managing ischemic complications are based on typical patterns seen in German hospitals. Our estimation of the life-years saved by using Eptifibatide is based on the DEALE method. All calculations are standardized to a hypothetical cohort of 100 treated patients. RESULTS: There are 0.064 saved life-years per patient. Cost-effectiveness of Eptifibatide is EUR 14,464 per life-year saved. CONCLUSION: Eptifibatide is cost-effective compared to other therapies in the treatment of acute coronary ischemic syndromes. The additional costs of using this substance should be reimbursed to the hospitals.

Impact of the reduction of anaesthesia turnover time on operating room efficiency.

BACKGROUND AND OBJECTIVE: We investigated whether an increase in anaesthesia staffing to permit induction of anaesthesia before the previous case had ended ('overlapping') would increase overall efficiency in the operating room. Hitherto, the average duration of operating sessions was too long, thus impeding the timely commencement of physicians' ward duties. METHODS: The investigation was designed as a prospective, non-randomized, interrupted time-series analysis divided into three phases: (a) a baseline of 3.5 months, (b) a 2.5 month intervention phase, in which anaesthesia staffing was increased by one attending physician and one nurse, and (c) a further 2 months under baseline conditions. Data focussed on process management were collected from operating room staff, anaesthesia personnel and surgeons using a structured questionnaire collected daily during the entire study. RESULTS: Turnover time between consecutive operations decreased from 65 to 52 min per operation (95% CI: 9; 17; P = 0.0001). Operating room occupancy increased from 4:28 to 5:27 h day-1 (95% CI: 50; 68; P = 0.005). The surgeons began their work on the ward 35 min (95% CI: 30; 40) later than before the intervention and their overtime increased from 22:36 to 139:50 h. CONCLUSIONS: The time between surgical operations decreased significantly. Increased operating room efficiency owing to overlapping induction of anaesthesia allows more intense scheduling of operations. Thus, physicians and nurses can be released to spend more time with their patients in the ward. Improving the efficiency of the operating room alone is insufficient to improve human resource management at all levels of a surgical clinic.
