Systematic review of cost effectiveness studies of telemedicine interventions

Abstract Objectives: To systematically review cost benefit studies of telemedicine. Design: Systematic review of English language, peer reviewed journal articles. Data sources: Searches of Medline, Embase, ISI citation indexes, and database of Telemedicine Information Exchange. Studies selected: 55 of 612 identified articles that presented actual cost benefit data. Main outcome measures: Scientific quality of reports assessed by use of an established instrument for adjudicating on the quality of economic analyses. Results: 557 articles without cost data categorised by topic. 55 articles with data initially categorised by cost variables employed in the study and conclusions. Only 24/55 (44%) studies met quality criteria justifying inclusion in a quality review. 20/24 (83%) restricted to simple cost comparisons. No study used cost utility analysis, the conventional means of establishing the “value for money” that a therapeutic intervention represents. Only 7/24 (29%) studies attempted to explore the level of utilisation that would be needed for telemedicine services to compare favourably with traditionally organised health care. None addressed this question in sufficient detail to adequately answer it. 15/24 (62.5%) of articles reviewed here provided no details of sensitivity analysis, a method all economic analyses should incorporate. Conclusion: There is no good evidence that telemedicine is a cost effective means of delivering health care.

Multifaceted national and regional drug reforms and initiatives in ambulatory care in Sweden: global relevance

It is a continual challenge trying to improve the quality of prescribing while concurrently trying to address increasing pharmaceutical development, utilization and expenditure. National and regional reforms and initiatives in Sweden have moderated growth in ambulatory drug expenditure to 2.7% per annum in recent years despite increasing volumes. National reforms include mandatory generic substitution and value-based pricing alongside devolution of drug budgets to the regions. Regional initiatives include strengthening the role of the regional Drug and Therapeutic Committees, further budget devolution as well as strategies incorporating prescribing guidance and monitoring coupled with financial incentives. The extent and nature of the regional initiatives vary depending on their characteristics. In this article, we compare initiatives undertaken in two major counties, Stockholm and Östergötland, and their outcomes. Outcomes include annual drug budget savings while achieving agreed quality as well as increased adherence to prescribing targets and guidance; the latter associated with savings. Appraising these multifaceted reforms can provide guidance to other countries and regions in view of their diversity. Future steps must incorporate measures to improve the utilization of new expensive drugs, which should include horizon scanning and forecasting activities as well as post-launch activities involving monitoring of prescribing and registries. This may well require cooperation with other European countries.

Detection of Endoleak with Enhanced Ultrasound Imaging: Comparison with Biphasic Computed Tomography

Purpose: To compare unenhanced and enhanced ultrasound imaging to biphasic computed tomography (CT) in the detection of endoleak after endovascular abdominal aortic aneurysm (AAA) repair. Methods: Fifty-three patients (44 men; mean age 70 years) were examined during 96 follow-up visits after endovascular AAA repair. All patients had color Doppler and power Doppler ultrasound studies performed before and after the administration of an ultrasound contrast agent. Biphasic (arterial and delayed) CT was performed on the same day, and the ultrasound and CT studies were independently scored to record the presence or absence of endoleak and the level of confidence in the observation. Results: The sensitivity of the ultrasound techniques to detect endoleak improved with the use of ultrasound contrast media, ranging from a low of 12% with unenhanced color Doppler to 50% with enhanced power Doppler. However, the enhanced power Doppler failed to detect 9 type II endoleaks identified by CT (86% negative predictive value for endoleak). There were only 2 graft-related endoleaks in the study; one was diagnosed from the ultrasound image, but the other had nondiagnostic ultrasound scans because of poor views. Conclusions: Ultrasound scanning with or without contrast enhancement was not as reliable as CT in diagnosing type II endoleak. CT imaging remains our surveillance modality of choice.

Recent national and regional drug reforms in Sweden: implications for pharmaceutical companies in Europe.

With an aging population and increased prevalence of chronic diseases, such as obesity and diabetes mellitus, drug reforms are needed across Europe to ensure the continued provision of comprehensive healthcare. It is also a challenge, with the limited resources available, to fund new innovative drugs that significantly improve patient health.Recent national and regional reforms in Sweden have moderated the rate of increase in drug expenditure, despite increased volumes of drug use and the launch of new, expensive drugs. National reforms include the adoption of economic principles when assessing the value and subsequent reimbursement of new and existing drugs, as well as reforms to obtain low prices for generic drugs. Regional reforms aim to encourage the rational use of medicines through the establishment of drug and therapeutic committees, development of guidelines, academic detailing, continuous benchmarking of prescribing patterns, and financial incentives.Some of these reforms provide examples to other European countries, whilst others duplicate existing measures. As such, we believe other European countries can benefit from an analysis of the Swedish reforms. We believe the pharmaceutical industry can also benefit from this analysis by working with key regional payers involved with developing and implementing the reforms as they moderate and refine their future activities, including finding acceptable ways of introducing new expensive drugs.

Ongoing pharmaceutical reforms in France: implications for key stakeholder groups.

The rapid rise in pharmaceutical costs in France has been driven by new technologies and the growing prevalence of chronic diseases as well as considerable prescribing freedom and choice of physician among patients. This has led to the introduction of a number of reforms and initiatives in an attempt to moderate expenditure whilst ensuring universal coverage and rewarding innovation. These reforms include accelerating access to and granting average European prices for new innovative drugs, delisting drugs where there are concerns over their value and instigating rebates for excessive prescribing. Alongside this, ongoing initiatives to improve the quality and efficiency of prescribing include programmes to enhance generic prescribing and dispensing as well as to reduce antibacterial and anxiolytic/hypnotic prescribing. However, there have been few publications documenting the impact of specific reforms on the overall costs and quality of care, which have been exacerbated by compartmentalization of budgets. Estimates suggest savings of over 27 million euro/year by decreasing antibacterial prescribing, 450 million euro/year by not reimbursing ineffective drugs, 670 million euro/year from pharmaceutical company rebates and approximately 1 billion euro/year from increased prescribing and dispensing of generics (year 2003-7 values). Additional savings of at least 1.5 billion euro/year are seen as being possible from increased use of generics such as generic proton pump inhibitors, statins (HMG-CoA reductase inhibitors) and ACE inhibitors instead of current branded products such as angiotensin II type 1 receptor antagonists (angiotensin receptor blockers [ARBs]). Delisting drugs when there are concerns about their value provides an example to other countries with currently limited demand-side measures. Other possible examples include price : volume agreements and multifaceted campaigns to enhance generic prescribing and dispensing and reduce antibacterial prescribing. Possible future initiatives could include adopting more stringent criteria for categorizing new drugs as innovative as well as further reductions in the prices of generics. Other initiatives could include further enhancement of the quality and efficiency of prescribing, including formal auditing of physician prescribing, as well as increasing efforts to monitor the risk : benefit ratio of new drugs post-launch in real-world practice.

A review of telemedicine cost-effectiveness studies

As interest in telemedicine grows, many of its proponents and vendors increasingly suggest that it is now time to move to full-scale implementation of telemedicine services in a variety of contexts throughout the world, and question the need for further evidence of its utility and cost-effectiveness. We have reviewed the published literature relating to cost-effectiveness studies in telemedicine and have identified some important weaknesses. Ten recommendations regarding the design of economic evaluations of telemedicine are suggested.

Accounting for Noncompliance in Pharmacoeconomic Evaluations

Noncompliance with prescribed drug regimens is a widespread phenomenon which results in decreased efficacy and is often associated with increased medical expenditures. Despite this, economic evaluations based on decision-analytic models rarely incorporate noncompliance to allow for the differences in compliance observed between controlled clinical trials and routine clinical practice.This review examines the issues relating to the measurement of noncompliance, and the clinical and economic consequences of noncompliant drug taking behaviour. In order to fully appreciate the clinical (and therefore the economic) consequences of noncompliance, a detailed understanding of the type of noncompliance, the pharmacokinetic and pharmacodynamic properties of the drug and the pathophysiological processes of the diseases being treated is required. These are described in detail, and a classification of drug-disease combinations according to the potential economic impact of the varying forms of noncompliance is set out.Issues are raised to highlight the need for improved modelling of the impact of noncompliance, and to this end, recommendations are made for future analyses. The main points are that compliance should be defined clearly, distinguishing between the various forms of noncompliance, that the assumptions relating to the health status of noncompliers should be explicit and robust, and that sensitivity analysis should be applied appropriately to ascertain the impact of noncompliance on the cost-effectiveness of drug therapies.

Insight into recent reforms and initiatives in Austria: implications for key stakeholders

Pharmaceutical expenditure continued to rise steadily in Austria during the 1990s and early 2000s despite a variety of reforms. However, recent reforms and initiatives have moderated the growth rate. These initiatives include transparent pricing of new drugs and generics, greater restrictions on the prescribing of new drugs and voluntary price reductions. Alongside this, there have also been initiatives to enhance rational and efficient prescribing. The lack of published data makes it difficult to fully analyze the impact of individual reforms. In addition, some reforms have only recently been introduced. Despite this, implications can be drawn for key stakeholder groups in the future. This includes pharmaceutical companies continuing to need to demonstrate substantially added benefit for their new drug to command average European prices. Otherwise, premiums will be restricted to a maximum 10% above the price of current standards. In addition, companies will need to continue to lower the price of their brands in interchangeable classes as standards become available as generics. The alternative will be prescribing restrictions. Further reforms will be needed in Austria to meet government growth targets for pharmaceutical expenditure of only 3–4% per annum, while continuing to fund new innovative drugs and increased volumes with greater prevalence of chronic diseases. Possible future measures and their implications for key stakeholder groups will also be discussed.

European countries with small populations can obtain low prices for drugs: Lithuania as a case history

Objectives: Assess whether European countries with smaller populations can obtain appreciable discounts for generics, similar to some of the larger European countries, to investigate the validity of recently published hypotheses. Methods: Observational study involving all 3.4 million ambulatory care patients currently contained within the compulsory health insurance system in Lithuania among four drug classes, with a particular focus on generics. Utilization measured in defined daily doses (DDDs). Prices in terms of reimbursed expenditure/DDD. Reductions in reimbursed expenditure/DDD for generic proton pump inhibitors, statins, angiotensin-converting enzyme inhibitors and selective serotonin reuptake inhibitors in either 2007 or 2009 were compared with 2000 or 2001 originator prices, as well as a range of European countries. Results: There was an appreciable reduction in reimbursed expenditure/DDD for generics in each drug class in Lithuania, such as 56% reduction for generic omeprazole, 65% for generic ramipril, 83% for generic simvastatin, 85% for generic sertraline and 87% for generic atorvastatin. This is despite appreciably lower utilization of proton pump inhibitors, statins and antidepressants in Lithuania versus Western European countries. Reductions in generic prices were similar to those among a range of European countries, with no apparent correlation between the number of competitors and price reductions in practice. Conclusion: European countries with smaller populations can obtain substantial reductions in prices of generics versus originators. This was seen in Lithuania among classes with currently limited utilization versus Western European countries, as well as those with similar utilization patterns. In addition, matching price reductions for generics were seen among Western European countries. Overall, our findings demonstrate that it is possible for European countries with smaller populations to engineer low prices with manufacturers.
