Tissue adhesives for traumatic lacerations: a systematic review of randomized controlled trials.
OBJECTIVE: To summarize the best available evidence for the effect of tissue adhesives (TAs) in managing traumatic lacerations in children and adults. METHODS: A search was conducted using the Cochrane Controlled Trials Register, Medline, and EMBase for relevant studies. The authors also searched the citations of selected studies and contacted relevant authors and manufacturers. The search included randomized controlled trials (RCTs) comparing a TA versus standard wound closure (sutures, staples, adhesive strips) (SWC) or two TAs for acute, linear, low-tension, traumatic lacerations in an emergency or primary care setting. Data were extracted by one reviewer and checked for accuracy by a second reviewer. Two reviewers independently assessed masked copies for quality. Outcomes of cosmesis (subgroups of age, wound location, and need for deep sutures), pain, procedure time, ease of use, and complications were analyzed separately for two comparisons: 1). TA versus SWC; and 2). TA versus TA. RESULTS: Eight studies compared a TA with SWC. No significant difference was found for cosmesis at any time point examined. Subgroup analysis was possible only for age; no significant difference was found. Pain scores [Parent Visual Analogue Scale weighted mean difference (VAS WMD) = -15.7 mm; 95% CI = -21.9 to -9.5] and procedure time (WMD = -5.7 minutes; 95% CI = -8.2 to -3.1) significantly favored TAs. Small, statistically significant risk differences were found for dehiscence [favoring SWC; number needed to harm (NNH) = 25; 95% CI = 14 to 100] and erythema (favoring TAs; NNH = 8; 95% CI = 4 to 100). Only one study compared two TAs (butylcyanoacrylate versus octylcyanoacrylate) for pediatric facial lacerations. No significant difference was found for cosmesis, pain, procedure time, or complications. CONCLUSIONS: TAs are an acceptable alternative to SWC for simple traumatic lacerations. No difference in cosmesis was found between TAs and SWC, or between different TAs. Tissue adhesives offer the benefits of decreased procedure time and less pain, compared with SWC. A small increased rate of dehiscence with TAs must be considered when choosing the closure method (NNH = 25).

Developing evidence-based librarianship: practical steps for implementation.
Evidence-based librarianship (EBL) is a relatively new concept for librarians. This paper lays out a practical framework for the implementation of EBL. A new way of thinking about research in librarianship is introduced using the well-built question process and the assignment of librarian research questions to one of six domains specific to librarianship. As a profession, librarianship tends to reflect more qualitative, social sciences/humanities in its research methods and study types which tend to be less rigorous and more prone to bias. Randomised controlled trials (RCT) do not have to be placed at the top of an evidence 'hierarchy' for librarianship. Instead, a more encompassing model reflecting librarianship as a whole and the kind of research likely to be done by librarians is proposed. 'Evidence' from a number of disciplines including health sciences, business and education can be utilized by librarians and applied to their practice. However, access to and availability of librarianship literature needs to be further studied. While using other disciplines (e.g. EBHC) as a model for EBL has been explored in the literature, the authors develop models unique to librarianship. While research has always been a minor focus in the profession, moving research into practice is becoming more important and librarians need to consider the issues surrounding research in order to move EBL forward.
