Hand-searches of Published Literature (Secondary Sources)
Searches of Electronic Databases
Description of Methods Used to Collect/Select the Evidence
Develop a Search Strategy
A search strategy based on the PICO (populations, interventions, comparisons, outcomes) was developed for each research question. A generic search strategy for ‘melanoma’ was used by most chapter groups, and additional limits were imposed with regard to patients, interventions, comparisons, outcomes or other relevant aspects. Keywords were devised for each search following discussion with the chapter leader(s) during the PICO process. Additional sources for keywords and MeSH or subject terms were determined by searching other relevant evidence-based clinical guidelines, systematic review articles, and literature pertaining to each question. These terms were then combined into a single systematic search strategy applied to all included electronic databases. For quality control, keywords, MeSH or subject terms, and searches were checked by other members in the chapter group, the University of Sydney’s medical librarian, and an National Health and Medical Research Council representative.
Search the Literature
Literature searching was conducted systematically using electronic databases concluding mid-2006 to early-2007, such as:
- Medline
- EMBASE
- PubMed
- Cinahl
- Cochrane Library
- AUSThealth
- Clinical Evidence
- Psychinfo
Search histories were dated, documented, and are available on request from the Australian Cancer Network or the New Zealand Guidelines Group (www.nzgg.org.nz ). The chapter leaders and the methods consultants were asked to provide details on the following:
- Electronic databases searched
- Terms used to search the databases
- Search inclusion/exclusion criteria dates the search included
- Abbreviations
- Methods used to assess the quality of the search
- Language
- Study type
In addition, chapter leaders and their expert groups were asked to hand search the reference lists at the end of their relevant articles to identify additional articles not identified through searches of the electronic databases. Finally, bi-annual meetings of the guidelines Working Party provided a forum for discussion and sharing of overlapping evidence, and/or discovery of unpublished literature and information from other key organisations.
Select and Sort the Literature
The literature generated by the electronic database searches was appraised for relevance to each question. The following steps were taken to select and sort the literature:
- Review titles from the search
- Review abstracts
- Where uncertain about relevance, download full text of article
- Identify articles answering the questions and those useful for background information
- Obtain articles from the Internet, library or interlibrary loans
- Sort studies by type (e.g., interventions, prognosis, diagnosis)
- Sort studies by design (e.g., systematic review, randomised controlled trial, cohort, case control, case series, descriptive)
- Determine whether systematic reviews account for all preceding literature
- Prepare folders to file searches, background papers and reviewed articles for each question addressed
- Enter selected articles for review into the guideline master list
- Assess the quality of the search and the appraisal
All articles emerging from this process as potentially relevant to a guidelines question were forwarded to the chapter leader for his/her consideration and for critical appraisal.

Methods Used to Analyze the Evidence
Systematic Review with Evidence Tables
Description of the Methods Used to Analyze the Evidence
Critical Appraisal and Summary
Relevant articles selected from the search were reviewed and summarised by the chapter leader. Each article was summarised in a template with headings such as the type of study, level of evidence, number and characteristics of patients, type of analysis, outcome measure and results. Each article was then critically appraised with respect to level of evidence, quality of evidence, size of the effect and relevance of the study, and documented in another template.
Details on the templates, rating systems, and criteria for the critical appraisal process, are outlined in the methods handbook available on request from the Australian Cancer Network or the New Zealand Guidelines Group (www.nzgg.org.nz ).
Assess the Body of Evidence
The body of literature was assessed by each chapter leader with respect to the volume of the evidence, its consistency, clinical impact, generalisability and applicability. These aspects were graded and documented in a template.
Methods Used to Formulate the Recommendations
Expert Consensus
Description of Methods Used to Formulate the Recommendations
These guidelines have been developed by the Australian Cancer Network and the New Zealand Guidelines Group.
In 2005, the Australian Cancer Network (ACN) agreed to facilitate a revision of the 1999 National Health and Medical Research Council (NHMRC) Clinical Practice Guidelines for the Management of Melanoma based upon advice from melanoma experts across Australia.
A multidisciplinary group comprising clinical experts, a consumer representative and an epidemiologist was convened to develop the guidelines. This group became known as the Guidelines Working Party. Experts from within or outside the Working Party were nominated to become chapter leaders or members of a chapter group. Further experts were added to the Working Party to lead a chapter group when additional topics were proposed at subsequent meetings. Members of the New Zealand Melanoma Reference Group also joined the Working party in 2006 and New Zealand melanoma experts were added as members of chapter groups.
In early Working Party meetings, it became apparent that the guideline development processes required by the NHMRC for national guidelines had changed somewhat since the last set of guidelines were developed. The processes had become much more scientifically rigorous and involved substantially more documentation of the development processes. In addition, several new questions were posed by clinicians in the Working Party that had not been addressed in the 1999 guidelines. In response, the Working Party decided to develop a new set of melanoma clinical practice guidelines incorporating the newer more rigorous processes and including additional topics, rather than just updating the previous guidelines.
The ACN received a grant from the Cancer Institute New South Wales (NSW) to assist in the development of the guidelines. The grant made it possible for the ACN to contract a consultancy group, the Sydney Health Projects Group at the University of Sydney, to assist in the development of project methods and to complete the searches for each chapter of the guidelines. Further assistance in the development of the guidelines was provided by staff of the NSW Melanoma Network and the New Zealand Guidelines Group. The whole process was monitored and assisted by a representative of the NHMRC Guidelines Assessment Register.
Further details of guideline development methods including the specific questions posed, search strategies, inclusion and exclusion criteria and literature appraisal templates for individual chapters are available on request from the Australian Cancer Network or the New Zealand Guidelines Group (www.nzgg.org.nz ).
Steps in the Preparation of NHMRC Clinical Practice Guidelines
All the chapter leaders and their expert working group went through the following steps to complete their recommendations. They received considerable assistance for the first four steps of this process from methods consultants, but the great majority of leaders completed their own critical appraisal and assessment of the body of evidence:
- Structure the research question
- Develop a search strategy
- Search the literature
- Select and sort the literature
- Critically appraise and summarise each selected article
- Assess the body of evidence and formulate recommendations
Structure the Research Question
All chapter leaders and their expert working group were asked to contribute key questions to be researched for this set of guidelines. Over 230 questions were submitted to the Working Party for consideration. The Working Party prioritised the questions for systematic review and decided upon a final list of about 70 questions.
All chapter leaders were asked to specify the purpose, scope and target audience for their questions and structure their question according to the PICO (populations, interventions, comparisons, outcomes) formula. Typically, chapter leaders achieved this and specification of a search strategy (see Description of Methods Used to Collect/Select the Evidence field above) during a 30-60 minute meeting with a methods consultant.
Formulate Recommendations
Following grading of the body of evidence, chapter leaders were asked to formulate a recommendation that related to the summarised body of evidence. This recommendation also had to be graded as specified in the "Rating Scheme for the Strength of the Recommendations."
Writing the Chapter
All the chapter leaders and their groups were asked to write their guidelines chapter using the following format:
- Background
- Review of the evidence
- Evidence summary with levels of evidence and numbered references
- Recommendation(s) and its grade
- References
Review of the Chapters
The body of evidence and recommendations for each chapter were reviewed by the Working Party and final recommendations agreed by consensus.
Rating Scheme for the Strength of the Recommendations
Grading of Recommendations

Good Practice Points
Good practice points are used when the conventional grading of evidence is not possible –these points represent the views of the Guideline Development Group.
Cost Analysis
A formal cost analysis was not performed and published cost analyses were not reviewed.
Method of Guideline Validation
External Peer Review
Internal Peer Review
Description of Method of Guideline Validation
A complete draft of the guidelines was sent out for public consultation in Australia and New Zealand in October 2007. In Australia, the consultation process included soliciting public review of the document through advertisements in a range of newspapers. In New Zealand, the draft guideline was widely circulated to all individuals and organisations identified by the New Zealand Melanoma Reference Group as having a potential interest in the document. A large conference meeting was also organized for clinicians and other interested parties in February 2008 to outline the major recommendations in the guideline and to provide a forum for further discussion and debate. All feedback received on the draft during the consultation period in Australia and New Zealand and from the conference meeting was reviewed by the Working Party and subsequent changes to the draft agreed by consensus.

Implementation of the Guideline
Description of Implementation Strategy
The Australian Cancer Network will lead in disseminating the guidelines in Australia and the New Zealand Guidelines Group will oversee the dissemination and implementation of the guidelines in New Zealand on behalf of the Ministry of Health. In both countries this will include a campaign to raise awareness of the new guidelines, with organized media coverage through multiple outlets and an official launch. Widespread dissemination will be achieved through distribution to relevant professional and other interested groups directly and through meetings, conferences, and other Continuing Medical Education (CME) events. A significant effort will be undertaken to have the Guidelines be introduced to senior undergraduate medical students and to encourage the relevant learned Colleges, which are bi-national (surgeons, radiation oncologists and pathologists), to support the Guidelines and to foster integration of the Guidelines into hospital and community practice through resident and registrar educational activity.
The scope of implementation activities will depend on funding available. It is recognized that a planned approach is necessary to overcome specific barriers to implementation in particular settings and to identify appropriate incentives to encourage uptake of guideline recommendations. Implementation of the guideline will require a combination of effective strategies and may include further CME initiatives and interactive learning, the development and promotion of computer assisted decision aids and electronic decision support systems, and the creation of audit and other clinical tools.
