A Review of: Perrier, L., Farrell, A., Ayala, A. P., Lightfoot, D., Kenny, T., Aaronson, E., . . . Weiss, A. ( 2014). Effects of librarian-provided services in healthcare settings: A systematic review. Journal of the American Medical Informatics Association, 21(6), 1118-1124. http://dx.doi.org/10.1136/amiajnl-2014-002825 Abstract Objective – To assess the effects of librarian-provided services, in any healthcare setting, on outcomes important to patients, healthcare providers, and researchers. Design – Systematic review and narrative synthesis. Setting – MEDLINE, CINAHL, ERIC, LISA, and CENTRAL databases; library-related websites, conference proceedings, and reference lists of included studies. Subjects – Twenty-five studies identified through a systematic literature search. Methods – In consultation with the review team, a librarian designed a search to be run in MEDLINE that was peer-reviewed against a published checklist. The team then conducted searches in the five identified databases, adapting the search as appropriate for each database. Authors also checked the websites of library and evidence based healthcare organisations, along with abstracts of relevant conference proceedings, to supplement the electronic search. Two authors screened the literature search results for eligible studies, and reached agreement by consensus. Studies of any librarian-delivered service in a healthcare setting, directed at either patients, clinicians of any type, researchers, or students, along with studies reporting outcomes relevant to clinicians, patients, or researchers, were eligible for inclusion. The authors assessed results initially on the titles and abstracts, and then on the full-text of potentially relevant reports. The data from included studies were then extracted into a piloted data extraction form, and each study was assessed for quality using the Cochrane EPOC risk of bias tool or the Newcastle-Ottawa scale. The results were synthesised narratively. Main Results – The searches retrieved a total of 25 studies that met the inclusion criteria, comprised of 22 primary papers and 3 companion reports. Authors identified 12 randomised trials, 4 controlled before-and-after studies, 3 cohorts, 2 non-randomised trials, and 1 case-control study. They identified three main categories of intervention: librarians teaching search skills; providing literature searching as a service; and a combination of the teaching and provision of search services. The interventions were delivered to a mix of trainees, clinicians, and students. None of the studies examined services delivered directly to patients or to researchers. The quality assessment found most of the studies had a mid- to high-risk of bias due to factors such as lack of random sequence generation, a lack of validated tools for data collection, or a lack of statistical analysis included in the study. Two studies measured patient relevant outcomes and reported that searches provided by librarians to clinicians had a positive impact on the patient’s length of stay in hospital. Five studies examined the effect of librarian provided services on outcomes important to clinicians, such as whether a literature search influenced a clinical decision. There was a trend towards a positive effect, although two studies found no significant difference. The majority of studies investigated the impact of training delivered to trainees and students on their literature search skills. Twelve of these studies found a positive effect of training on the recipients’ search skills, while three found no difference. The secondary outcomes considered by this review were satisfaction with the service (8 studies), relevance of the answers provided by librarians (2), and cost (3). The majority reported good satisfaction, and relevance. A cost benefit was found in 2 of 3 studies that reported this outcome. Conclusion – Authors report a positive effect of training on the literature search skills of trainees and students, and identified a benefit in the small number of studies that examined librarian services to clinicians. Future studies should use validated data collection tools, and further research should be conducted in the area of services provided to clinicians. Research is needed on the effect of librarian-provided services to patients and researchers as no studies meeting the inclusion criteria examining these two groups were identified by the literature search.

Shed Light

Quantitative Ethnography is a nascent field now formulating the specifics of its conceptual framework and terminology for a unified, quantitative – qualitative methodology. Our living, systematic review aims to shed light on decisions in research design that the community has made thus far in the domain of data collection, coding & segmentation, analysis, and how Quantitative Ethnography as a methodology is conceptualized. Our analysis intends to spur discussions on these issues within the community and help establish a lingua franca.

Qualitative Data Collection

A systematic review of articles using qualitative methods to generate questionnaire items identified in MEDLINE and PsycINFO from 2000 to 2014 was carried out. Articles were analyzed for (a) year of publication and journal domain, (b) qualitative data collection methods, (c) method of data content analysis, (d) professional experts’ input in item generation, and (e) debriefing of the newly developed items. In total, 371 articles were included and results showed (a) an acceleration of published articles, (b) individual interviews and focus groups were common ways of generating items and no emergent approach was identified, (c) the content analysis was usually not described (43% of articles), (d) experts were involved in eliciting concepts in less than a third of articles, (e) 61% of articles involved a step of further submission of newly developed items to the population of interest. This review showed an insufficient reporting of qualitative methods used to generate new questionnaires despite previous recommendations.

The Cost

Background. The World Health Organization is planning a pilot introduction of a new malaria vaccine in three sub-Saharan African countries. To inform considerations about including a new vaccine in the vaccination program of those and other countries, estimates from the scientific literature of the incremental costs of doing so are important. Methods. A systematic review of scientific studies reporting the costs of recent vaccine programs in sub-Saharan countries was performed. The focus was to obtain from each study an estimate of the cost per dose of vaccine administered excluding the acquisition cost of the vaccine and wastage. Studies published between 2000 and 2018 and indexed on PubMed could be included and results were standardized to 2015 US dollars (US$). Results. After successive screening of 2119 titles, and 941 abstracts, 58 studies with 80 data points (combinations of country, vaccine type, and vaccination approach–routine v. campaign) were retained. Most studies used the so-called ingredients approach as costing method combining field data collection with documented unit prices per cost item. The categorization of cost items and the extent of detailed reporting varied widely. Across the studies, the mean and median cost per dose administered was US$1.68 and US$0.88 with an interquartile range of US$0.54 to US$2.31. Routine vaccination was more costly than campaigns, with mean cost per dose of US$1.99 and US$0.88, respectively. Conclusion. Across the studies, there was huge variation in the cost per dose delivered, between and within countries, even in studies using consistent data collection tools and analysis methods, and including many health facilities. For planning purposes, the interquartile range of US$0.54 to US$2.31 may be a sufficiently precise estimate.

Meta Analyses

A systematic review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA), to generate a document that supports the development of future research, compiling the various studies focused on the analysis of the pedestrian-vehicle interaction at unsignalized crosswalks. Firstly, 381 studies were identified by applying the search protocol in the database sources; however, only nine studies were included in this review because most of the studies are not focused on this type of crosswalks or have not considered the micro-simulation perspective. For each study, an analysis of the used methodology for data collection was carried out, in addition to what type of model it was applied, including the variables that represent the PVI (Pedestrian-Vehicle Interaction). The outcomes obtained by this systematic review show that although the video camera observation technique is the most used, it is possible to complement them with other tools to add specific field information. Additionally, variables such as the adjacent yields, speed variables vehicles, pedestrian attitude, and the number of pedestrians waiting at the crossing were those most used in the cellular automata model or micro-simulation, which are the commonly developed models to simulate this interaction.

Abstract Objective We performed a systematic review to assess the effectiveness and safety of Tribulus terrestris to treat female sexual dysfunction (FSD). Data sources We performed unrestricted electronic searches in the MEDLINE, CENTRAL, EMBASE, LILACS, CINAHL, PsycINFO, WHO-ICTR, Clinicaltrials.gov and OpenGrey databases. Selection of studies We included any randomized controlled trials (RCTs) that compared T. terrestris versus inactive/active interventions. After the selection process, conducted by two reviewers, 5 RCTs (n = 279 participants) were included. Data collection Data extraction was performed by two reviewers with a preestablished data collection formulary. Data synthesis Due to lack of data and clinical heterogeneity, we could not perform meta-analyses. The risk of bias was assessed by the Cochrane Risk of Bias (RoB) tool, and the certainty of evidence was assessed with Grading of Recommendations, Assessment, Development and Evaluations (GRADE). Results After 1 to 3 months of treatment, premenopausal and postmenopausal women randomized to T. terrestris had a significant increase in sexual function scores. Three months of treatment with T. terrestris showed a significant increase in the serum testosterone levels of premenopausal women. There was no report of serious adverse events, and none of the studies assessed health-related quality of life. The certainty of the evidence was very low, which means that we have very little confidence in the effect estimates, and future studies are likely to change these estimates. Conclusion More RCTs are needed to support or refute the use of T. terrestris. The decision to use this intervention should be shared with the patients, and the uncertainties around its effects should be discussed in the clinical decision-making process.Number of Protocol registration in PROSPERO database: CRD42019121130
