Pre-coverage assessments of new hospital interventions on Austria: methodology and 3 years of experience

Antibiotic prescription after tooth extraction in adults: a retrospective cohort study in Austria

BACKGROUND

Broad spectrum antibiotics are often used for the prophylaxis of infectious endocarditis and treatment of odontogenic infections, but there are limited data related to antibiotic use and adherence to prescription guidelines.  METHODS: Data from patients with tooth extraction between 2014 and 2018 were selected from a database of a regional health insurance fund. We created three data sets, one based on all tooth extractions, one on multiple teeth extractions, and one including only single tooth extraction. After data collection, descriptive analysis was carried out. The differences in prescription pattern of antibiotic medicine were tested by χ² test, Student´s t-test or ANOVA.

RESULTS

From 43,863 patients with tooth extraction, 53% were female, and 3,983 patients (9.1%) filled a prescription for antibiotic medicine. From 43,863 patients, 157 patients (0.4%) had endocarditis risk, but only 8 patients of these (5.1%) filled an antibiotic prescription. In total, 9,234 patients had multiple and 34,437 patients had only one tooth extraction. Patients with more than one tooth extraction received more often antibiotic treatment (10.7%) compared to those with single tooth extractions (χ² = 36; p < 0,001). Patients with more than one tooth extraction were older, however, younger patients received antibiotics more frequently (t = 28,774, p = 0.001). There was no relationship with endocarditis risk status. Clindamycin and amoxicillin/clavulanic acid were the most frequently prescribed antibiotic medicines.

CONCLUSIONS

In this retrospective cohort study, dentists did not discriminate prophylactic antibiotic prescription with regard to endocarditis risk status. A factor influencing prescribing behaviour of antibiotic medicines was the number of extracted teeth.

Reimbursement decisions for medical services in Austria: an analysis of influencing factors for the hospital individual services catalogue between 2008 and 2020

OBJECTIVES

To (1) describe the (evidence-based) reimbursement process of hospital individual services, (2) evaluate the accordance between evidence-based recommendations and reimbursement decision of individual services and (3) elaborate potential aspects that play a role in the decision-making process in Austria.

METHOD

The reimbursement process is described based on selected relevant sources such as official documents. Evidence-based recommendations and subsequent reimbursement decisions for the annual maintenance of the hospital individual service catalogue in Austria between 2008 and 2020 were analysed using a mixed methods approach, encompassing descriptive statistics and a focus group with Austrian decision makers.

RESULTS

118 evidence-based recommendations were analysed. There were 93 (78.8%) negative and 25 (21.2%) positive evidence-based recommendations. In total, 107 out of 118 evidence-based recommendations (90.1%) did not lead to a deviating reimbursement decision. We identified six aspects that may have played a role in the decision-making process for the annual maintenance of the hospital individual service catalogue, with clinical evidence being the most notable. Further aspects included quality assurance/organisational aspects (i.e., structural quality assurance), costs (if comparable to already existing medical services, not: cost-effectiveness), procedural aspects (e.g., if certain criteria for adoption have not been met formally through the proposals), "other countries" (i.e., taking into account how other countries decided) and situational aspects (such as the COVID-19 pandemic).

CONCLUSIONS

There is good accordance between evidence-based recommendations and reimbursement decisions regarding hospital individual services in Austria. Beyond clinical evidence, organisational aspects seem to be considered often with regard to quality assurance but costs do not appear to play a major role. The Austrian system has mechanisms in place that can restrict widespread adoption of novel hospital individual services with uncertain clinical benefits. Future studies could investigate how well these mechanisms work and how they compare to other health systems in Europe.

Extracorporeal Cytokine Adsorption Therapy As a Preventive Measure in Cardiac Surgery and As a Therapeutic Add-On Treatment in Sepsis: An Updated Systematic Review of Comparative Efficacy and Safety

OBJECTIVES

Evaluating whether there is a clinical benefit of using extracorporeal cytokine adsorption therapy in two indications.

DESIGN

Systematic review.

SETTING

Search on four databases, Medline, Embase, The Cochrane Library, and the European Network for Health Technology Assessment planned and ongoing projects database.

PATIENTS

Patients with sepsis/septic shock; patients undergoing cardiac surgery.

INTERVENTIONS

Cytokine adsorption.

MEASUREMENTS AND MAIN RESULTS

Randomized controlled trials and prospective studies with concurrent control were eligible for the evidence synthesis. The quality of the individual studies and the strength of the available evidence were assessed using the Cochrane risk of bias tool and the Grading of Recommendations, Assessment, Development, and Evaluation approach, respectively. For the preventive treatment of extracorporeal cytokine adsorption therapy in patients undergoing cardiac surgery, we found very low-quality inconclusive evidence for mortality (five randomized controlled trials, n = 163), length of stay in the ICU (five randomized controlled trials, n = 163), and length of hospitalization (three randomized controlled trials, n = 101). Very low-quality inconclusive evidence was found for (serious) adverse events (four randomized controlled trials, n = 148). For the therapeutic treatment of extracorporeal cytokine adsorption therapy in patients with sepsis/septic shock, we found very low-quality inconclusive evidence for mortality up to 60-day follow-up (two randomized controlled trials, n = 117), organ function (two randomized controlled trials, n = 117) and length of stay in the ICU (one randomized controlled trial, n = 20). Very low-quality inconclusive evidence was found for (serious) adverse events (two randomized controlled trials, n = 117).

CONCLUSIONS

Given the available evidence, the efficacy and safety of extracorporeal cytokine adsorption therapy in combination with standard care in the investigated indications was not established. We strongly recommend considering well-powered studies with patient-relevant endpoints instead of investing further research funds on studies that may not shed light on the clinical benefit of extracorporeal cytokine adsorption therapy.

The status of health economic evaluation within decision making in Austria

BACKGROUND

Given limited resources compared to the demand for them, spending resources efficiently is important. Key methods applied for supporting efficient resource allocation are health economic evaluations.

METHODS

Based on secondary literature, we analyze international challenges for using two types of economic evaluations-cost-effectiveness analysis and cost-utility analysis-in reimbursement decisions and reflect on them for the Austrian case.

RESULTS

The main challenges with the application of economic evaluations are related to the methods, the decision-making culture, and the respective system. The challenges also apply to the Austrian Bismarck system, where almost no formal requirements for using economic evaluations exist, except on a case-by-case basis. Resource allocation in Austria hence occurs, for the most part, implicitly.

CONCLUSION

One way forward towards more explicit efficiency considerations may be to consider more descriptive study types and foster capacity building, standardization of methods and presentation of results, and a mandatory detailed guideline.

Pre-reimbursement: early assessment for coverage decisions

Background

In the past decade, the Ludwig Boltzmann Institute for Health Technology Assessment (LBI-HTA) has introduced two programs: “Horizon Scanning in Oncology” (HSO) and extra medical services (“MELs”), which are to facilitate coverage decisions based on early assessments. This article aims to outline the general process and methods within these two programs.

Methods

A narrative-descriptive synthesis of the literature was performed to outline the general and LBI-HTA-specific processes and methods of early assessments.

Results

In total, 79 HSO assessments (2009–2018) and 95 MELs (2008–2018) have been conducted by the LBI-HTA. Recently, additional methods that contribute to European applicability have been introduced into these programs.

Conclusions

Overall, pre-coverage decisions based on early assessment reports are dependent on the existing evidence. However, the organisation of the health care system and the cross-linking between decision-makers and HTA institutions can have an impact.

INFLUENCE OF HEALTH TECHNOLOGY ASSESSMENT AND ITS MEASUREMENT

Objectives: The aim of this study was to obtain information on methods used to measure health technology assessment (HTA) influence, decisions that were influenced, and outcomes linked to HTA.

Methods: Electronic databases were used to locate studies in which HTA influence had been demonstrated. Inclusion criteria were studies that reliably reported consideration by decision makers of HTA findings; comparative studies of technology use before and after HTA; and details of changes in policy, health outcomes, or research that could be credibly linked to an HTA.

Results: Fifty-one studies were selected for review. Settings were national (24), regional (12), both national and regional (3) hospitals (9), and multinational (3). The most common approach to appraisal of influence was review of policy or administrative decisions following HTA recommendations (51 percent). Eighteen studies (35 percent) reported interview or survey findings, thirteen (26 percent) reviewed administrative data, and six considered the influence of primary studies. Of 142 decisions informed by HTA, the most common types were on routine clinical practice (67 percent of studies), coverage (63 percent), and program operation (37 percent). The most frequent indications of HTA influence were on decisions related to resource allocation (59 percent), change in practice pattern (31 percent), and incorporation of HTA details in reference material (18 percent). Few publications assessed the contribution of HTA to changing patient outcomes.

Conclusions: The literature on HTA influence remains limited, with little on longer term effects on practice and outcomes. The reviewed publications indicated how HTA is being used in different settings and approaches to measuring its influence that might be more widely applied, such as surveys and monitoring administrative data.

IDENTIFYING AND SELECTING NEW PROCEDURES FOR HEALTH TECHNOLOGY ASSESSMENT: A DECADE OF NICE EXPERIENCE IN THE UNITED KINGDOM

Objectives: The aim of this study was to analyze the experience of the National Institute for Health and Care Excellence (NICE) in identifying new procedures entering the United Kingdom (UK) healthcare system, for assessment and publication of recommendations on their use. This system is designed to provide guidance in an area where regulation is lacking worldwide.

Methods: Retrospective analysis of all procedures notified to the Interventional Procedures Programme (NICE) between 2002 and 2012. Notifications were analyzed year by year for their source (who notified them), clinical specialties involved, and whether guidance was subsequently published.

Results: A total of 1,094 procedures were notified by clinicians (51 percent), and by others, including hospitals (6 percent), horizon scanners (5 percent), patients (4 percent), private health insurers (4 percent), and medical device manufacturers (3 percent). Guidance was published on 44 percent of procedures notified to the program. There was a decrease in the numbers of procedures notified during 2003–2012 (p = .049). There were notifications across all specialties, with the largest numbers in general surgery (125), urology (104), orthopedics (99), interventional radiology (93), cardiology (82), and obstetrics and gynecology (82).

Conclusions: The “open” NICE Web portal allows anyone to notify new procedures, aiming to maximize the opportunity of identifying all those procedures entering clinical practice. This has resulted in identification of large numbers of procedures from across the whole range of medical specialties. The fact that similar proportions of procedures notified from diverse sources have been selected for assessment and publication of practice recommendations suggests that this inclusive approach is worthwhile.

Contrasting clinical evidence for market authorisation of cardio-vascular devices in Europe and the USA: a systematic analysis of 10 devices based on Austrian pre-reimbursement assessments

BACKGROUND

European medical device regulation is under scrutiny and will be re-regulated with stricter rules concerning requirements for clinical evidence for high-risk medical devices. It is the aim of this study to analyse the differences between Europe and USA in dealing with risks and benefits of new cardio-vascular devices.

METHODS

Since no information is available on clinical data used by the Notified Body for CE-marking, data from Austrian pre-reimbursement assessments close to European market approval were used as proxy and compared with clinical data available at time of market approval by FDA in the USA.

RESULTS

10 cardio-vascular interventions with 27 newly CE approved medical devices were analysed. The time lag between market authorisation in Europe and in the USA is 3 to 7 years. Only 7 CE-marked devices also hold a FDA market approval, 7 further devices are in FDA approved ongoing efficacy trials. For 4 of the CE-marked devices the FDA market application or the approval-trial was either suspended due to efficacy or safety concerns or the approval was denied. Evidence available at time of CE-marking are most often case-series or small feasibility RCTs, while large RCTs and only in rare cases prospective cohort studies are the basis of FDA approvals. Additionally, the FDA often requires post-approval studies for high-risk devices.

CONCLUSIONS

Market authorisation based on mature clinical data deriving from larger RCTs and longer follow-ups do not only change the perspective on the risk-benefit ratio, but also secures real patient benefit and safety and assures payers of investing only in truly innovative devices.
