|Developing HIV/AIDS Treatment Guidelines (UNAIDS, 1999, 43 p.)|
1. Managing drug supply: the selection, procurement, distribution and use of pharmaceuticals, 2nd ed. WHO Action Programme on Essential Drugs, Geneva, and Management Sciences for Health (Kumarian Press), West Hartford, Connecticut, 1997, 11:13-14.
This chapter examines the development of treatment guidelines, essential drugs lists and formulary manuals. Insight into the development process and the important factors that need to be considered in making this process successful are given. Practical examples of the development of guidelines and their success or failure are given from different parts of the world. The guideline development process advocated is useful and effective as shown by the examples of the success of the process, however, there is very little guidance given about evidence-based guideline development.
2. Grimshaw JM, Russell IT. Achieving health gain through clinical practice guidelines I: Developing scientifically valid guidelines. Quality in health care, 1994, 2:243-248.
There is considerable uncertainty about the effectiveness of clinical management guidelines and how to introduce them into clinical practice. Interest in their role in encouraging good practice and generating health gains is discussed. A systematic review of 59 rigorous evaluations of clinical management guidelines identified improvements in the process of care in 55 studies and suggested that guidelines can change clinical practice when they were appropriately developed, disseminated, and implemented.
3. Grimshaw JM, Russell IT. Achieving health gain through clinical practice guidelines II: Developing scientifically valid guidelines. Quality in health care, 1994, 3:45-52.
A systematic review of 59 published rigorous evaluations of clinical management guidelines covering a wide range of clinical activities shows that all but four detected statistically significant improvements in the process of medical care. Two of the 11 that measured the outcome of care reported statistically significant improvements in outcome. It was concluded that guidelines improve clinical practice and achieve health gains when introduced in the context of rigorous evaluations. This evidence-based approach to the development of guidelines is comprehensive and produces valid guidelines but is time consuming and can be costly.
4. Putnam RW, Curry L. Impact of patient care appraisal on physician behaviour in the office setting. Canadian medical association journal, 1985, 132:1025-1029.
The effect of patient care appraisal on physicians' management of patients' problems was assessed. Sixteen family physicians were involved. Eight in the experimental group helped in the selection of two of the five disease conditions to be audited and in the generation of optimum criteria of care for two of the conditions. It was concluded that patient care appraisal is an effective tool in continuing medical education that leads to improvement in the quality of care, provided the process focuses on essential criteria of care. Patient care appraisal is an implementation strategy that is easily introduced as part of patient care but requires a system of monitoring to be effective.
5. Guidelines for the clinical management of HIV infection in adults and children. CAREC, PAHO, WHO. Port of Spain, Trinidad and Tobago, West Indies, 1994.
Guidelines for the clinical management of HIV infection in children and adults in the Caribbean are elaborated in one document. The form of the guideline is algorithms with annotations based on the WHO model of HIV clinical management guidelines. The process of development was through an expert committee and a consensus workshop. A multidisciplinary approach to their development was used. Documentation of the process undertaken in identifying the scientific evidence before and during the workshop is lacking but the overall comprehensiveness of the guideline is evidence of the quality of discussion and the variety of participants in the meeting.
6. Adapting WHO guidelines for the clinical management of HIV infection to country needs. Geneva, World Health Organization, 1994 (unpublished document WHO/GPA/TCO/HCS/94.8 available on request from UNAIDS, 20 Avenue Appia, CH-1211 Geneva 27, Switzerland).
These guidelines are to assist countries in adapting the WHO guidelines for the clinical management of HIV infection in adults and children to country needs. The methodology advocated involves organizing national or programme-based workshops using the nominal group technique. A step-by-step outline is given of the key activities to successfully conduct this. A coordinator is to be appointed to organize the meeting and an expert in the nominal group process is to be appointed to lead the discussions in the meeting. The outcome of the meeting is then used to develop country-specific HIV clinical management guidelines. These guidelines, however, do not emphasize the identification and statement of the strength of evidence upon which recommendations are based.

These are guidelines for the management of early HIV infection developed by the United States Department of Health and Human Services. In the guideline preparation, scientific evidence was identified and recommendations developed with a grading of the strength of evidence. The guideline document has a section explaining the procedures used in developing the document. A review was conducted first by a team of 45 outside peer reviewers including clinicians, AIDS directors, social workers, counsellors, health educators and clinical researchers. A consumer guideline was also developed and reviewed by 25 consumers, 16 providers and 100 HIV-positive individuals and their families before being disseminated. The procedures used were sufficiently comprehensive and rigorous to ensure the validity of the document.
8. Criteria for appraising clinical guidelines for national use. Scottish Intercollegiate Guidelines Network. Centre for Medical Education, University of Dundee 1995. (Available at http://www.pc.47.cee.hw.ac.uk/sign/home/html)
Generic criteria for assessing the validity of clinical practice guidelines are provided focusing on the guideline development process, group selection and the key disciplines required for the appraisal. The identification, synthesis of evidence and linking of this to recommendations is discussed. The role of content and format of guidelines in assessing validity is also discussed. A tool for appraising guidelines is presented including the reporting format. This booklet sets out a clear and practical format for conducting a rapid appraisal of guidelines. The appraisal results also make evident which aspects of the guideline need improvement to ensure the development of a valid product.
9. Eisenberg JM. Sociologic influences on decision-making by clinicians. Annals of internal medicine, 1997, 90:957-964.
Recent articles on clinical decision-making have proposed sophisticated quantitative methods for improving the physician s clinical judgement. Actual clinical decisions, however, are influenced by interactions between the clinician, the patient and the social cultural milieu as well as biomedical considerations. This paper explores four types of sociological factors that influence the clinician s judgement, the characteristics of the patient; the characteristics of the clinician; the clinician s interaction with his profession and the health-care system; and the clinician s relationship with the patient. Assessing the impact of non-clinical aspects of decision-making is important to ensure successful application of clinical guidelines.

No algorithms or flow charts are included. Good cross-references to other sources are included elsewhere in the book and in the Malawi HIV management guidelines.
12. Mulrow CD. Systematic review: rationale for systematic reviews. British medical journal, 1994, 309:597-599.
Health care providers, researchers and policy makers are inundated with unmanageable amounts of information; they need systematic reviews to integrate existing information effectively and to provide data for rational decision-making. Systematic reviews establish whether scientific findings are consistent and can be generalized across population settings and treatment variations. The methodologies proposed are intensive and appropriate for evidence-based guideline development.
13. Series on the systematic review of clinical literature to ensure its validity and acceptability for use as evidence in the development of clinical guidelines. British medical journal, 1994, 309:597-599, 648-651, 719-721, 789-791, 1007-1010, 1286-1291, 1351-1355.

21. Guidelines for the clinical management of HIV in adults. Geneva, World Health Organization, 1991 (unpublished document WHO/GPA/IDS/HCS/91.6 available on request from UNAIDS, 20 Avenue Appia, CH-1211 Geneva 27, Switzerland).
The guidelines are to assist health care workers in the diagnosis and management of HIV infection in adults at the primary, secondary and tertiary levels of the health care system. They were developed by a group of international clinical experts working in the field of HIV using a nominal group process. The guidelines are presented in the form of algorithms with annotations on the common signs and symptoms of HIV disease. The notable features of the guidelines are:
- the guidelines are well written and have a clear layout,
- all the common symptoms in HIV infection and the required treatment are covered adequately,
- the guidelines have formed the basis for the development of many national guidelines. However,
- concepts of comprehensive care and referral systems are not included,
- topics related to terminal care, counselling, pain relief and nutrition were not included in this edition,
- the source and grading of the scientific evidence used in the recommendations are not clearly indicated.
22. Guidelines for the clinical management of HIV in children. Geneva, World Health Organization, 1993 (unpublished document WHO/GPA/IDS/HCS/93.3 available on request from UNAIDS, 20 Avenue Appia, CH-1211 Geneva 27, Switzerland).
The guidelines are to assist health care workers in the diagnosis and management of HIV infection in children at the primary, secondary and tertiary levels of the health care system. They were developed by a group of international clinical paediatric experts working in the field of HIV using a nominal group process. The guidelines are presented in the form of algorithms with annotations on the commonly seen signs and symptoms of HIV disease in children. The notable features are similar to those in the guideline for adults except that a section on counselling has been included.

This report describes the process of adapting the clinical management guidelines for the Caribbean region and the outcome of this process. It also describes the current HIV/AIDS care activities in the region and the reported HIV prevalence and AIDS cases.
24. Fink A et al. Consensus methods: Characteristics and guidelines for use. American journal of public health, 1984; 979-983.
Consensus methods are being used increasingly to solve problems in medicine and health. Their main purpose is to define levels of agreement on controversial subjects. Advocates suggest that, when properly employed, consensus strategies can create structured environments in which experts are given the best available information allowing solutions to problems to be more justifiable and credible than otherwise. The paper surveys several major methods, such as the Delphi nominal group and models developed by the National Institutes of Health and the guideline developer, Dr Glasser. It provides guidelines for those who want to use the techniques. Concerns raised are selection of problems, choosing members of consensus panels, specifying acceptable levels of agreement, proper use of empirical data, or obtaining professional/political support and disseminating results.

Prostate cancer treatment was reviewed by the United States National Institute of Health Consensus Development Conference in June 1987. Data from the US National Cancer Institute Surveillance, epidemiology and end results of tumour registers were analysed. This examination showed that the proportion of eligible prostate cancer patients receiving the recommended therapies did not increase at a faster rate than before. This highlights the importance of developing implementation and dissemination strategies for successful guidelines.
