NOW FOR AN ORIGINAL PAPER ASSIGNMENT:Discussion: Single Study Design

Perceived weaknesses. Restricting studies for inclusion to a single study design such as randomized controlled trials, as practised in the early years of the Cochrane Collaboration, can limit the application of this methodology to providing insights about effectiveness rather than seeking answers to more complex search questions; for example, why a particular intervention is effective.

Example. Weightman, A. L. & Williamson, J. The value and impact of information provided through library services for patient care: a systematic review. Health Information and Libraries Journal 2005, 22(1), 4–25.

Systematic search and review

Description. Such a review combines the strengths of a critical review with a comprehensive search process. Typically, this type of review addresses broad questions and the result is a ‘best evidence synthesis’.

Perceived strengths. The broad scope of this type of review means that it often incorporates multiple study types rather than focusing on a single preferred study design. They can thus provide a much more complete picture of the prevalence of research on a topic than a systematic review limited to randomized controlled trials. Subjecting the resultant literature to critical review or critique, albeit informally without the use of a standardized tool or checklist, provides a useful evaluative component. However, this presupposes that all included articles are being assessed and valued against the same underlying criteria, a fact that cannot usually be determined from the review’s methods.

Perceived weaknesses. While the initial search process may meet the exacting requirements of a systematic review, the subsequent critical review may be prone to some of the limitations of the traditional review. Without explicit inclusion and exclusion criteria and a clearly defined process of synthesis, the result may be a subjective selection of research to support a particular line of argument.

Example. Carroll, L. J., Cassidy, J. D., Peloso, P. M., Garritty, C. & Giles-Smith, L. WHO Collaborating Centre Task Force on mild traumatic brain injury. Systematic search and review procedures: results of the WHO Collaborating Centre Task Force on mild traumatic brain injury. Journal of Rehabilitation Medicine 2004, 43(Suppl.), 11–4.

Systematized review

Description. Systematized reviews attempt to include one or more elements of the systematic review process while stopping short of claiming that the resultant output is a systematic review. They may identify themselves parenthetically as a ‘systematic’ review. Systematized reviews are

RESPONSIVENESS TO DISCUSSION QUESTION

Discussion post minimum requirements:

*The original posting must be completed by Wednesday, Day 3, at 11:59pm MST. Two response postings to two different peer original posts, on two different days, are required by Saturday, Day 6, at 11:59pm MST. Faculty member inquiries require responses, which are not included in the minimum number of posts. Your Discussion Board postings should be written in standard edited English and follow APA style for format and grammar as closely as possible given the constraints of the online platform. Be sure to support the postings with specific citations from this week’s Learning Resources as well as resources available through the Walden University online databases. Refer to the Essential Guide to APA Style for Walden Students to ensure your in-text citations and reference list are correct.
