Abstract Objectives This article aims to provide a brief review of information retrieval and hospital-based health technology assessment (HB-HTA) and describe library experiences and working methods at a regional HB-HTA center from the center's inception to the present day. Methods For this brief literature review, searches in PubMed and LISTA were conducted to identify studies reporting on HB-HTA and information retrieval. The description of the library's involvement in the HTA center and its working methods is based on the authors’ experience and internal and/or unpublished documents. Results Region Västra Götaland is the second largest healthcare region in Sweden and has had a regional HB-HTA center since 2007 (HTA-centrum). Assessments are performed by clinicians supported by HTA methodologists. The medical library at Sahlgrenska University Hospital works closely with HTA-centrum, with one HTA librarian responsible for coordinating the work. Conclusion In the literature on HB-HTA, we found limited descriptions of the role librarians and information specialists play in different units. The librarians at HTA-centrum play an important role, not only in literature searching but also in abstract and full-text screening.

INTRODUCTION:Hospital mangers need information for decision making (1). Hospital-based health technology assessment (HTA) methods were tested out to support the budget planning of investments for a new building to be constructed for diagnostic and teaching units at a publicly funded tertiary care university hospital. The hospital board nominated an ad hoc working group to reassess all investment proposals for devices, equipment and furniture for the diagnostic or teaching units that intended to move into the new building. The need for assessment was obliged when the submitted proposals of the units exceeded two-fold the initially allocated investment budget.METHODS:Depending on the level of expenditure, all proposals were assessed by one of the following processes: (i) Proposals over EUR250,000 were evaluated by three to five person expert groups using multi-domain assessment adapting Hospital-based HTA-principles; (ii) Proposals between EUR50,000 and EUR250,000 were returned to the units for miniHTA-assessments by clinicians who submitted the initial proposals and (iii) All proposals below EUR50,000 were prioritized by the units to cut the expenditure by at least 25 percent, with a special emphasis on synergistic use of devices and equipment among the units.RESULTS:The expert groups suggested significant reductions to the proposals, including the withdrawal of a Magnetic Resonance Imaging (MRI)-unit considered to be suboptimally located. Furthermore, the need for a new scanner was declined by promoting adherence to evidence-based diagnostic guidelines and more efficient utilization of existing scanners. Self-assessed MiniHTAs revealed proposals that were unnecessary or the specifications for devices needed re-adjustments. Prioritization revealed excess numbers of devices, for instance the number of cold storage appliances could be reduced. Altogether, the investment proposals were cut by over EUR3.8 million to reach the initial budgetary allocation.CONCLUSIONS:Innovative and flexible usage of hospital-based HTA methodology can be applied to budget planning and evaluation of investment proposals to support decision making. Based on encouraging results, hospital-based HTA was accepted to become a part of hospital strategy as a tool for the annual investment planning.

Abstract Health technology assessment conducted to inform decisions during technology development (development-focused or DF-HTA) has a number of distinct features compared with HTA conducted to inform reimbursement and usage decisions. In particular, there are a broad range of decisions to be informed related to the development of a technology; multiple markets and decision makers to be considered; a limited (and developing) evidence base; and constrained resources for analysis. These features impact upon methods adopted by analysts. In this paper, we (i) set out methods of DF-HTA against a timeline of technology development; (ii) provide examples of the methods’ use; and (iii) explain how they have been adapted as a result of the features of DF-HTA. We present a toolkit of methods for analysts working with developers of medical technologies. Three categories of methods are described: literature review, stakeholder consultation, and decision analytic modeling. Literature review and stakeholder consultation are often used to fill evidence gaps. Decision analytic modeling is used to synthesize available evidence alongside plausible assumptions to inform developers about price or performance requirements. Methods increase in formality and complexity as the development and evidence base progresses and more resources are available for assessment. We hope this toolkit will be used in conjunction with the framework of features of DF-HTA presented in our earlier article in order to improve the clarity and appropriateness of methods of HTA used in DF-HTA. We also seek to contribute to a continuing dialogue about the nature of, and the best approach to, DF-HTA.

Background. The Health Technology Assessment (HTA) is used to evaluate health services, manage healthcare processes more efficiently, and compare medical technologies. The aim of this paper is to carry out an HTA study that compares two pharmacological therapies and provides the clinicians with two models to predict the length of hospital stay (LOS) of patients undergoing oral cavity cancer surgery on the bone tissue. Methods. The six Sigma method was used as a tool of HTA; it is a technique of quality management and process improvement that combines the use of statistics with a five-step procedure: “Define, Measure, Analyze, Improve, Control” referred to in the acronym DMAIC. Subsequently, multiple linear regression has been used to create two models. Two groups of patients were analyzed: 45 were treated with ceftriaxone while 48 were treated with the combination of cefazolin and clindamycin. Results. A reduction of the overall mean LOS of patients undergoing oral cavity cancer surgery on bone was observed of 40.9% in the group treated with ceftriaxone. Its reduction was observed in all the variables of the ceftriaxone group. The best results are obtained in younger patients (−54.1%) and in patients with low oral hygiene (−52.4%) treated. The regression results showed that the best LOS predictors for cefazolin/clindamycin are ASA score and flap while for ceftriaxone, in addition to these two, oral hygiene and lymphadenectomy are the best predictors. In addition, the adjusted R squared showed that the variables considered explain most of the variance of LOS. Conclusion. SS methodology, used as an HTA tool, allowed us to understand the performance of the antibiotics and provided variables that mostly influence postoperative LOS. The obtained models can improve the outcome of patients, reducing the postoperative LOS and the relative costs, consequently increasing patient safety, and improving the quality of care provided.

INTRODUCTION:Available data in the scientific literature is not always sufficient to make a clear Health Technology Assessment (HTA) recommendation without any other source of data. Contextual data and local expertize are an important source of data that cannot be ignored in HTA process. Despite a lack of evidence in the scientific literature, a technology can be recommended in a given context. We illustrate this by a case study about biplane angiography for vascular neurointervention.METHODS:A systematic review was conducted. The level of evidence was assessed by the grid of Downs and Black. An analysis of the context in our setting was also conducted. The main outcomes were: radiation doses, clinical complications, procedure times, purchase cost, impact on teaching programs, confidence of clinicians in the technology, quality of care, and volume of activity. A committee constituted of managers, clinical experts, physicians, physicists and HTA experts was created to produce a recommendation about biplane technology acquisition.RESULTS:A list of 257 citations was obtained yielding 9 eligible articles for analysis. Despite the lack of evidence found in the literature (median of Downs and Black: 3/32), the biplane system appears to reduce ionizing radiation and medical complications as well as shorten procedure time. Contextual data indicated that biplane system could improve operator's confidence, which could translate into reduced risk, especially for complex procedures. We estimate that a minimum of 50 cases can be done in our context (University hospital center covering a population of 306,322 people) with a higher level of patient safety. In addition, the biplane system can support our institution in advanced procedures teaching program.CONCLUSIONS:Given on the advantages provided by the biplane technology in our setting, the committee has recommended its acquisition. However, this technology should be implemented with a responsibility in collecting outcome data to optimize clinical protocol in doses of ionizing delivered.
