Scoping searches

Scoping searches were undertaken in September 2009 using the following websites and databases (listed in alphabetical order); browsing or simple search strategies were employed. The search results were used to provide information for scope development and project planning.

Main searches

The following sources were searched for the topics presented in the sections below.

  • Cochrane Database of Systematic Reviews – CDSR (Wiley)
  • Cochrane Central Register of Controlled Trials – CENTRAL (Wiley)
  • Database of Abstracts of Reviews of Effects – DARE (CRD Databases)
  • Health Technology Assessment Database HTA (CRD Databases)
  • CINAHL (EBSCO and NHS Evidence – Search 2.0)
  • EMBASE (Ovid)
  • MEDLINE (Ovid)
  • MEDLINE In-Process (Ovid)
  • PSYCINFO (Ovid)

The searches were conducted in November 2009. The aim of the searches was to provide evidence on colonoscopic surveillance (using conventional colonoscopy or chromoscopy) for prevention and early detection of colorectal cancer compared with no surveillance. Search filters for systematic reviews, randomised controlled trials, and observational studies were appended to the search strategies to retrieve high quality papers (see Identification of systematic reviews, randomised controlled trials, and observational studies).

The MEDLINE search strategy is presented below. It was translated for use in all of the other databases.

Identification of evidence on surveillance using other methods

The searches were conducted in November 2009. The aim of the searches was to provide evidence on colonoscopic surveillance (using conventional colonoscopy or chromoscopy) for prevention and early detection of colorectal cancer compared with surveillance using other methods, such as flexible sigmoidoscopy, double-contrast barium enema, computed tomographic colonography,and tri-modal imaging (high resolution white light endoscopy, narrow-band imaging and auto-fluorescence imaging).

Sources

The following sources were searched to identify economic evaluations and quality of life data relating to colonoscopic surveillance (using conventional colonoscopy or chromoscopy) for prevention and early detection of colorectal cancer compared with no surveillance

  • Health Economic Evaluations Database – HEED (Wiley)
  • NHS Economic Evauation Database – NHS EED (Wiley and CRD website)
  • EMBASE (Ovid)
  • MEDLINE (Ovid)
  • MEDLINE In-Process (Ovid)

Strategies

The searches were undertaken in November 2009. The MEDLINE search strategy presented in the sections RQ1 and RQ2 were used and translated for use in NHS EED and HEED. Filters to retrieve economic evaluations and quality of life papers were appended to the MEDLINE search strategy to identify relevant evidence.
