Speech Recognition in the Radiology Department: A Systematic Review:

Objective: to conduct a systematic review of the literature describing the impact of speech recognition systems on report error rates and productivity in radiology departments. Methods: The search was conducted for relevant papers published from January 1992 to October 2013. Comparative studies reporting any of the following outcomes were selected: error rates, departmental productivity, and radiologist productivity. The retrieved studies were assessed for quality and risk of bias. Results: The literature search identified 85 potentially relevant publications, but, based on the inclusion and exclusion criteria, only 20 were included. Most studies were before and after assessments with no control group. There was a large amount of heterogeneity due to differences in the imaging modalities assessed and the outcomes measured. The percentage of reports containing at least one error varied from 4.8% to 89% for speech recognition, and from 2.1% to 22% for transcription. Departmental productivity was improved with decreases in report turnaround times varying from 35% to 99%. Most studies found a lengthening of radiologist dictation time. Conclusion: Overall gains in departmental productivity were high, but radiologist productivity, as measured by the time to produce a report, was diminished.

Percutaneous coronary intervention with second-generation drug-eluting stent versus bare-metal stent: Systematic review and cost–benefit analysis

Background Drug-eluting stents (DESs) were considered as ground-breaking technology promising to eradicate restenosis and the necessity to perform multiple revascularization procedures subsequent to percutaneous coronary intervention. Soon after DESs were released on the market, however, there were reports of a potential increase in mortality and of early or late thrombosis. In addition, DESs are far more expensive than bare-metal stents (BMSs), which has led to their limited use in many countries. The technology has improved over the last few years with the second generation of DESs (DES-2). Moreover, costs have come down and an improved safety profile with decreased thrombosis has been reported. Objective Perform a cost–benefit analysis of DES-2s versus BMSs in the context of a publicly funded university hospital in Quebec, Canada. Methods A systematic review of meta-analyses was conducted between 2012 and 2016 to extract data on clinical effectiveness. The clinical outcome of interest for the cost–benefit analysis was target-vessel revascularization (TVR). Cost units are those used in the Quebec health-care system. The cost–benefit analysis was based on a 2-year perspective. Deterministic and stochastic models (discrete-event simulation) were used, and various risk factors of reintervention were considered. Results DES-2s are much more effective than BMSs with respect to TVR rate ratio (i.e., 0.29 to 0.62 in more recent meta-analyses). DES-2s seem to cause fewer deaths and in-stent thrombosis than BMSs, but results are rarely significant, with the exception of the cobalt–chromium everolimus DES. The rate ratio of myocardial infraction is systematically in favor of DES-2s and very often significant. Despite the higher cost of DES-2s, fewer reinterventions can lead to huge savings (i.e., -

769 per patient). Moreover, the higher a patient’s risk of reintervention, the higher the savings associated with the use of DES-2s. Conclusion Despite the higher purchase cost of DES-2s compared to BMSs, generalizing their use, in particular for patients at high risk of reintervention, should enable significant savings.

The value of wetlands in Quebec: a comparison between contingent valuation and choice experiment

Background: The effects of cancer and associated treatments have a considerable impact on the well-being and quality of life of pediatric oncology patients. To support children and their families, complementary and alternative medicines are seen by nurses and doctors as practical to integrate to the services offered by hospitals. Objective: The purpose of this paper is to examine if the practice of complementary and alternative medicine, specifically spiritual care and treatments based on body manipulation, is likely to improve the health and well-being of children suffering from cancer. Method: This objective is achieved through a systematic review of the literature. The level of evidence associated with each practice of complementary and alternative medicine was assessed according to the methodological design used by the studies reviewed. Results and Conclusion: Studies reviewed are of a methodological quality that could be described as fair due to the small sample size of patients and the existence of a number of biases in the conduct and analysis of these studies. However, results obtained are consistent from one study to another, allowing us to make certain recommendations. It is thus advisable to consider the introduction of hypnotherapy in pediatric oncology services. Based on the data collected, it is the complementary and alternative medicine with the most evidence in favor of effectiveness of the well-being of pediatric oncology patients, especially during painful procedures. It is also recommended to use art therapy and music therapy. Conversely, too little evidence is present to be able to recommend the use of acupuncture, chiropractic or osteopathy.

New design of care: Assessment of an interdisciplinary orthopaedic clinic with a pivot nurse in the province of Quebec.

This paper describes a comparative study of clinical coding by Archivists (also known as Clinical Coders in some other countries) using single and dual computer monitors. In the present context, processing a record corresponds to checking the available information; searching for the missing physician information; and finally, performing clinical coding. We collected data for each Archivist during her use of the single monitor for 40 hours and during her use of the dual monitor for 20 hours. During the experimental periods, Archivists did not perform other related duties, so we were able to measure the real-time processing of records. To control for the type of records and their impact on the process time required, we categorised the cases as major or minor, based on whether acute care or day surgery was involved. Overall results show that 1,234 records were processed using a single monitor and 647 records using a dual monitor. The time required to process a record was significantly higher (p= .071) with a single monitor compared to a dual monitor (19.83 vs. 18.73 minutes). However, the percentage of major cases was significantly higher (p= .000) in the single monitor group compared to the dual monitor group (78% vs. 69%). As a consequence, we adjusted our results, which reduced the difference in time required to process a record between the two systems from 1.1 to 0.61 minutes. Thus, the net real-time difference was only 37 seconds in favour of the dual monitor system. Extrapolated over a 5-year period, this would represent a time savings of 3.1 % and generate a net cost savings of

7,729 CAD (Canadian dollars) for each workstation that devoted 35 hours per week to the processing of records. Finally, satisfaction questionnaire responses indicated a high level of satisfaction and support for the dual-monitor system. The implementation of a dual-monitor system in a hospital archiving department is an efficient option in the context of scarce human resources and has the strong support of Archivists.

The Economic Value of the Greater Montreal Blue Network (Quebec, Canada): A Contingent Choice Study Using Real Projects to Estimate Non-Market Aquatic Ecosystem Services Benefits

ABSTRACT This study aims to evaluate the non-market values of ecosystem services generated by wetlands in southern Quebec. To accomplish this, we evaluated the value of wetland services related to (1) habitat for biodiversity, (2) flood control, (3) water quality and (4) climate regulation. Two non-market valuation methods are proposed, contingent valuation and choice experiment. Our study aims to measure both the populations willingness to pay (WTP) for wetland preservation and restoration and to understand which environmental attributes and socioeconomic characteristics motivate peoples responses. We also compared the results of the two methods. Our conclusion suggests that the two methods provide statistically convergent WTP values, both in total value and in relative importance for different attributes involved. Our result also confirms the coefficient equivalence between the estimation models using the data from the two methods.

Pressure Infusion Cuff and Blood Warmer during Massive Transfusion: An Experimental Study About Hemolysis and Hypothermia

BACKGROUND: New designs of care in orthopaedic clinics are needed to cope with the shortage of orthopaedic surgeons and the lengthening of waiting times. OBJECTIVE: To assess the effectiveness of an interdisciplinary orthopaedic clinic with a pivot nurse in the Canadian province of Quebec with regard to accessibility, quality of care, efficacy and efficiency of the clinic, and patients quality of life. METHODS: Two strategies were developed: (1) a selected cohort of new patients attending an orthopaedic service from February to September 2008 were entered into a database recording patient details, source of referral, diagnosis, satisfaction, and quality of life (36-Item Short Form Health Survey version 2). In this setting, 2 sets of questionnaires were administered to the patients: the first one during the first visit and the second one, 2 months later. A total of 243 patients from the case control were compared with 89 patients of the case study, where an interdisciplinary orthopaedic clinic with a pivot nurse has been developed; (2) costs per patient were calculated using the staff timesheets provided by the two orthopaedic clinics. RESULTS: The results showed a significant reduction in the waiting-list duration (accessibility) in the case study clinic owing to a strong decrease in the inappropriate consultations with the orthopaedic consultant. The quality of care remained high, and the target surgeries for total hip and knee replacement were reached, despite a strong shortage of orthopaedic doctors. CONCLUSION: Interdisciplinary orthopaedic clinic with a pivot nurse is a new approach in the province of Quebec and first results are encouraging.

The Health Technology Assessment Unit of the Centre hospitalier universitaire de Sherbrooke (Canada)

OBJECTIVES The aim of this study was to present the experience of a Canadian hospital-based health technology assessment (HTA) unit that performed the traditional functions of the HTA process along with many other activities to facilitate the choice of smart pumps. METHODS A rapid literature review was initiated, but little evidence was found. Moreover, the evidence provided was too far from our hospital context. To help our decision makers, we offered them a list of various services based on the skills of our HTA unit staff. RESULTS To involve our HTA unit in the choice of the new smart pumps led to a strong collaboration between hospital services. After a rapid review on smart pumps, we proceeded to establish the clinical needs, followed by an evaluation of technical features. To ascertain clinical needs, we participated in the establishment of a conformity list for the tender, a failure and mode-effect analysis, an audit on the use of actual smart pumps, and simulation exercises with nurses and doctors to evaluate the ease of use and ergonomics. With regard to technical tests, these were mainly conducted to identify potential dysfunction and to assess the efficiency of the pump. This experience with smart pumps was useful for evidence-based procurement and led to the formulation of a nine-step process to guide future work. CONCLUSIONS HTA units and agencies are faced with rapid development of new technologies that may not be supported by sufficient amount of pertinent published evidence. Under these circumstances, approaches other than evidence-based selection might provide useful information. Because these activities may be different from those related to classic HTA, this widens the scope of what can be done in HTA to support decision making.
