A Clinical Practice Guideline (CPG) is an evidence-based statement that assists patients and health care providers make appropriate decisions about cancer care. CPGs are developed and updated through the systematic review of the health care literature by Disease Site Groups (DSG), teams of health care providers, community representatives and researchers for Ontario's cancer system.
Materials and Methods:
In this study, the researchers conducted monthly searches of the literature using the Medline, CancerLit, HealthStar, and Cochrane Library electronic databases as well as information from meeting prodeedings.
80 pieces of new evidence were discovered over one year, including abstracts and published papers
Of them, there were 56 new randomized trials, 6 updates of randomized trials, 3 meta analyses, and 15 other studies
Modifications were made in 4 CPGs based upon 15 randomized trials
No modification was made to change the original recommendations
The updating process is necessary to maintain CPG credibility
Monthly updating and modification is not justified
The clinical practice guidelines are general and intended to be adapted to many different situations, taking into account the needs and resources particular to the locality, the institution, or the type of practice
Variations and innovations that improve the quality of patient care are to be encouraged rather than restricted
