NSUOCO Library Resources

Library resources and services that support the learning, research, and patient care needs of the NSUOCO faculty, students, and residents are available 24/7 from the library’s Optometry web page. It is our goal to provide authoritative resources that meet the following objectives:

  • To provide a mechanism for students to access the most current optometry, vision science, eye care, and medically related information
  • To familiarize students with specific information resources and library services to support the literature review required for OPT 6111 and OPT 6122
  • To familiarize students with evidence-based optometry and life-long learning techniques

Remote Access

You will have access to databases and online articles as well as other library resources and services 24/7. You will be prompted to enter your NSUID and Password in order to login to the library’s resources from a remote computer. If you have any problems with your id or password, please contact Tom Tinnell or a technical support staff member in Optometry. If you have problems with any of the library resources after successfully logging in, please email me as soon as possible so the appropriate technical support staff can be contacted.

The following terms, relevant to discussions of evidence-based practice, are excerpted from:
Ebell MH, Siwek J, Weiss BD, et al. Strength of recommendation taxonomy (SORT): a patient-centered approach to grading evidence in the medical literature. J Am Board Fam Pract. 2004;17(1):59-67. http://www.jabfm.org/content/17/1/59.full.pdf

Disease Oriented Outcomes. These outcomes include intermediate, histopathologic, physiologic, or surrogate results (ie, blood sugar, blood pressure, flow rate, coronary plaque thickness) that may or may not reflect improvements in patient outcomes.

Patient-Oriented Outcomes. These are outcomes that matter to patients and help them live longer or better lives, including reduced morbidity, reduced mortality, symptom improvement, improved quality of life, or lower cost.

Level of Evidence. The validity of an individual study that is based on an assessment of its study design.

Strength of Recommendation. The strength (or grade) of a recommendation for clinical practice is based on a body of evidence (typically more than one study). This approach takes into account the level of evidence of individual studies, the type of outcomes measured by these studies (patient-oriented or disease-oriented), the number, consistency, and coherence of the evidence as a whole, and the relationship between benefits, harms, and costs.

Practice Guideline (Evidence-Based). These guidelines are recommendations for practice that involve a comprehensive search of the literature, an evaluation of the quality of individual studies, and recommendations that are graded to reflect the quality of the supporting evidence. All search, critical appraisal, and grading methods should be described explicitly and be replicable by similarly skilled authors.

Practice Guideline (Consensus). Consensus guidelines are recommendations for practice based on expert opinions that typically do not include a systematic search, an assessment of the quality of individual studies, or a system to label the strength of recommendations explicitly.

Research Evidence. This evidence is presented in publications of original research, involving collection of original data or the systematic review of other original research publications. It does not include editorials, opinion pieces, or review articles (other than systematic reviews or meta-analyses).

Review Article. A nonsystematic overview of a topic is a review article. In most cases, it is not based on an exhaustive, structured review of the literature and does not evaluate the quality of included studies systematically.

Systematic Reviews and Meta-Analyses. A systematic review is a critical assessment of existing evidence that addresses a focused clinical question, includes a comprehensive literature search, appraises the quality of studies, and reports results in a systematic manner. If the studies report comparable quantitative data and have a low degree of variation in their findings, a meta-analysis can be performed to derive a summary estimate of effect.

Access Medicine provides comprehensive patient education materials in pdf format for adults and children. Includes separate handouts for common conditions and drugs and medicines

Resources for Literature Review and Manuscript Preparation

Style Manuals

Style manuals detail the structure of documents considered acceptable for academic and professional publication. The format of citations, grammar, and punctuation of the manuscript are given. Style manuals are frequently consulted to determine how to cite and format a reference list or bibliography. Professional associations, academic disciplines, and journal publishers usually require use of specific styles for both manuscripts and references.

Information on journal requirements can be found at the specific journal publisher’s web site under “instructions to authors”. For example, instructions for manuscript preparation and examples of various types of references for submission to the Optometry and Vision Science journal can be found at http://edmgr.ovid.com/ovs/accounts/ifauth.htm

Commonly used style manuals are available online and in the library’s reference collection.

Crediting others for their ideas and work and providing the reader with accurate citations that lead to the original work is both an ethical and legal responsibility of authors and presenters of scientific information. The University of Oklahoma Health Sciences Center maintains an excellent web site about plagiarism that includes helpful links to additional information. The web site is available at http://libguides.ouhsc.edu/content.php?pid=409099&sid=3346953

Plagiarism is defined similarly in the NSU and NSUOCO handbooks. Please consult your course instructor for guidance. The library provides bibliographic management software, RefWorks, to assist you in preparing your manuscript and bibliographies. Click on the link from the library’s Optometry web page.

Reuse of Copyrighted Images

Capturing and downloading images, figures, and tables from online book chapters and journal articles is often accomplished with one or two clicks. A brief video demonstrating how to capture images with copyright information on Clinical Key can be found on the Optometry e-Journals A to Z by Title web page. These works are almost always protected by copyright, and it is important to reuse them within fair use guidelines. Several academic health sciences web sites, such as the Oklahoma State University Center for Health Sciences Library, provide overviews of copyright usage guidelines that specifically address how to determine whether or not use qualifies as fair use.
