Publicly funded cancer medicines listed on the New Zealand Pharmaceutical Schedule were compared with those listed on the Australian Pharmaceutical Benefits Scheme. To quantify the health gains offered by the cancer medicines funded in Australia but not in New Zealand, clinical trial data reporting median progression-free survival (PFS) and overall survival (OS) were sought. The differences in the median PFS and OS for the unfunded medicines, relative to the comparator medicine funded in NZ, were then assessed against the American Society of Clinical Oncology Cancer Research Committee (ASCO-CRC) recommended targets for clinically meaningful health gains. Our analysis confirms that, whilst New Zealand funds fewer cancer medicines than Australia, most of the additional medicines funded in Australia do not deliver clinically meaningful health gains as defined by the ASCO-CRC guidance. This suggests that New Zealand is not missing substantive opportunities for improvements to New Zealand’s cancer survival rates through additional medicines funding. A policy of funding more new cancer medicines in order to achieve numerical parity with Australia or other countries would not result in substantive health improvement and would cost significantly more, and investing the millions of dollars needed to achieve funding parity with other countries would not represent good value for money in terms of delivering the best health outcomes for all New Zealanders, rather selective funding of new medicines that demonstrate clear clinical benefit and that are cost-effective and affordable is the sensible approach.  相似文献

BackgroundUnsafe and dangerous medical devices have entered the European market during the last decade, raising public awareness. Consequently, regulatory processes and their requirements for evidence are under discussion.ObjectiveThis research aims to explore the authorization and reimbursement processes and associated evidence requirements for high-risk medical devices in four regions: Europe, the United States, Australia and Canada.MethodsA literature search in PubMed about the authorization and reimbursement processes in the four regions was performed. Seven high-risk medical devices were selected as examples, and their authorization and reimbursement status were analyzed. Information was extracted from publicly available summaries of the authorization agencies of the regions, from the Controlled Clinical Trial Database, supplemented by information from HTA and reimbursement organizations.ResultsThe evidence required for the authorization and reimbursement processes differs strongly in the four regions regarding the levels of methodology and scrutiny. All seven devices have been authorized in Europe, three in Australia, one in the USA, and one in Canada. Currently none of the devices is recommended for reimbursement in the regions except one, in the USA. Devices that have been authorized in more than one region show that authorization has been two to three years earlier in Europe.ConclusionHuge differences and gaps in the evidence required for market authorization and for reimbursement were observed, especially between the two processes (authorization and reimbursement) in Europe. To ensure the high quality and safe provision of medical devices, harmonization of requirements and transparency in processes are needed.  相似文献

Cardiac contractility modulation in patients with heart failure refractory to drug treatment aims to strengthen myocardial activity through transmission of nonexcitatory impulses to the heart. The present study reviewed a total of 251 patients from four studies; the results, however, showed a low level of evidence. Crossover analysis showed a strong placebo effect for patients with implants that were switched on after three months. The technology is still in the development stage and further studies are needed.  相似文献

Hysteroscopy is considered the gold standard for the evaluation of intracavitary pathology in both premenopausal and postmenopausal patients associated with abnormal uterine bleeding, as well as for the evaluation of infertile patients with suspected cavity abnormalities. Office-based operative hysteroscopy allows patients to resume activities immediately and successfully integrates clinical practice into a “see and treat” modality, avoiding the added risks of anesthesia and the inconvenience of the operating room. For 2017, the Centers for Medicare and Medicaid Services has provided a substantial increase in reimbursement for a select number of office-based hysteroscopic procedures. This review provides an update on the indications, equipment, and procedures for office hysteroscopy, as well as the management of complications that may arise within an office-based practice.  相似文献

In recent decades cancer care has seen improvements in the speed and accuracy of diagnostic procedures; the effectiveness of surgery, radiation therapy and medical treatments; the power of information technology; and the development of multidisciplinary, specialist-led approaches to care. Such innovations are essential if we are to continue improving the lives of cancer patients across Europe despite financial pressures on our healthcare systems. Investment in innovation must be balanced with the need to ensure the sustainability of healthcare budgets, and all health professionals have a responsibility to help achieve this balance. It requires scrutiny of the way care is delivered; we must be ready to discontinue practices or interventions that are inefficient, and prioritise innovations that may deliver the best outcomes possible for patients within the limits of available resources. Decisions on innovations should take into account their long-term impact on patient outcomes and costs, not just their immediate costs. Adopting a culture of innovation requires a multidisciplinary team approach, with the patient at the centre and an integral part of the team. It must take a whole-system and whole-patient perspective on cancer care and be guided by high-quality real-world data, including outcomes relevant to the patient and actual costs of care; this accurately reflects the impact of any innovation in clinical practice. The European CanCer Organisation is committed to working with its member societies, patient organisations and the cancer community at large to find sustainable ways to identify and integrate the most meaningful innovations into all aspects of cancer care.  相似文献

Abstract

Spinal cord injury is a relatively infrequent but often catastrophic injury. As such, it presents special challenges for the individuals affected and the clinicians who care for them. Claims for reimbursement of acute care, rehabilitation, and long-term care are often denied, requiring patients and clinicians to exhaust every effort to ensure coverage for therapeutic interventions, preventive care, and durable medical equipment. Ethical dilemmas are presented within the framework of the US healthcare system, and practical strategies are discussed.  相似文献

BackgroundThe cost of Saudi healthcare continues to rise at an alarming rate, putting the sustainability of the public healthcare system into question. Data have shown that hospital and healthcare providers’ services represent the bulk of this rising cost, which makes the calls to reform the Saudi healthcare system more focused on payment models than at any time before.ObjectiveThe aim of this paper is to review various identified payment models that can be used to contain costs and improve the quality of the care provided.MethodA literature review of articles addressing the issues of cost containment and improving the quality of healthcare by reforming the current Saudi healthcare payment policy were identified through the Ovid®, Medline, and Google® Scholar search engines.Results and ConclusionsMany research articles and literature reviews have identified and discussed different models of healthcare payments. Some articles have focused on one payment model, while others have discussed different payment models that have been identified. There is an urgent need to reform the current system of healthcare payments to improve the quality of healthcare and maintain funding for universal healthcare coverage in the future. Future healthcare payment reforms should consider restructuring the current healthcare system, which is largely fragmented by providing incentives to different governmental healthcare sectors, in order to transform it into a more organized and coordinated system. Thus far, there is not a single payment model that can, by itself, reduce healthcare costs and improve healthcare quality. Future healthcare reforms should use a mixture of different payment models to pay hospitals and physicians.  相似文献
