Guide to Pain Management in Low-Resource Settings Uriah Guevara-Lopez and Alfredo Covarrubias-Gomez Chapter 44 Setting up Guidelines for Local Requirements Case report A 65-year-old Mexican woman reported generalized ab- dominal pain. She went to a rural medical practitioner in San Juan de Bautista, who prescribed 30 mg of ketoro- lac t.i.d. After 2 days the pain had not stopped, and she returned for medical assistance; this time, the physician added to his prescription 90 mg of etoricoxib per day. Af- ter two more days, the pain continued, and the woman went to a regional hospital located 10 miles from her home in Lloredo. In the hospital a uterine cancer with omental and liver metastasis was diagnosed, and ad- equate pain management was provided. Th e prescription from the rural practitioner drew the attention of local health authorities. Th ey asked the clinician about his prescription and about his knowledge about Mexican practice guidelines for cancer pain management. Th e physician responded that he had heard of them but he did not know about their content or recommendations, although he had received education on Mexican practice guidelines for pain management: he had attended a 1-month fellowship in the regional hospi- tal, and was also encouraged to promote education to lo- cal organizations about the guidelines and their benefi ts. A follow-up program for pain management evaluation in his community was established. So what went wrong? What are practice guidelines? Th e original concept of practice guidelines (PGs) was described as “a recommendation for patient manage- ment that identifi es one or more strategies for treat- ment”. However, in 1990, the Institute of Medicine in the United States defi ned PGs as “systematically developed statements to assist practitioner and patient decisions about appropriate health care for specifi c clinical cir- cumstances” (see Table 1). Th is defi nition had been gen- erally accepted. Guidelines are not rules or standards; they are helpful, fl exible syntheses of all the available, relevant, good-quality information applicable to a particular clin- ical situation that the clinician and patient need to make a good decision. Since medical knowledge, techniques, and technology are in constant development; PG must be actualized and improved in certain time intervals. Why do we need practice guidelines? Medical knowledge is under a continuous evolution. Assume, that a physician knows everything about a dis- ease or its treatment on the basis of training and clini- cal judgement, but continuing medical education was not available. Since there is a great chance, that medi- cal concepts have changed meanwhile, the physician’s 330 Uriah Guevara-Lopez and Alfredo Covarrubias-Gomez diagnostic and therapeutic approaches are outdated meaning either impaired effi cacy or decreased safety. Th e speed of medical evolution has complicated medical decision making; for that reason, PG may be used as an instrument to assist the clinician. Th is objec- tive is possible because PG summarizes the collective ex- perience and establishes grades to scientifi c knowledge. Are there diff erent types of practice guidelines? Attempts to regulate PG had been made since the early 1980s. Nowadays, diff erent types of practice guidelines can be identifi ed: (i) for the diagnosis and management of specifi c clinical circumstances, (ii) for risk manage- ment, (iii) for the improvement of quality systems, (iv) for medical regulation, (v) for education, and (vi) for preventive care. Why do we need practice guidelines for pain management? Pain is considered a health problem in few countries, but the number of countries where pain management becomes a health care priority is increasing. Th e de- velopment of PG in pain medicine is supported by the following issues: (i) the number of surgical inter- ventions is increasing in many low-resource countries without any concept to control postoperative pain; (ii) the demographic change (increase of older population) worldwide will be associated with a growing preva- lence of cancer pain; (iii) the frequency of chronic non cancer pain is recognized more today, for which it has been estimated, that the annual treatment costs equal or exceed exceeds those for coronary disease, cancer and AIDS. Additionally, pain has a signifi cant impact on physical function and activity, return-to-work-quota, social and family relations as well as the general psy- choaff ective state of the aff ected patient. Th is may prove to be a burden for the family of the patient, but also to the society as a whole, since insuffi cient pain manage- ment is a major cause for increased use of health care resources. Th erefore, health care policies need the im- plementation of rationalized instruments that can op- timize and improve the quality of medical attention for the most relevant diseases including pain syndromes. How are practice guidelines developed? Th ere is a general agreement, that PG must be submit- ted to public scrutiny, revised regularly in response to medical advances, and derived from high quality scien- tifi c evidence. PG must be easy to comprehend, inclu- sive, and manageable. Th e method for evidence selec- tion must be explained and the criteria used to grade each recommendation must be explained. Protocols for developing guidelines have many common features: (i) Reviews of existing research fi nd- ings are conducted, often with the aid of the National Library of Medicine. (ii) Studies are selected according to predetermined criteria and fi ndings are summarized using techniques such as meta-analysis or systematic reviews. (iii) Panels of experts are convened and guide- lines are revised according to feedback received. (iv) Consensus is achieved in some areas; and where dis- agreement or uncertainty remains and more research is needed, the developers describe this defi ciency. Strategies for developing PG have been pro- posed by diverse groups worldwide, a summary of those is described in Table 2. Table 1 Defi nition of practice guidelines and other terms that are confused with practice guidelines Concept Defi nition Practice guidelines A systematically developed statement to assist practitioner and patient decisions about appropriate health care for specifi c clinical circumstances. “Protocol” is often used interchangeably with “guideline,” although some view “practice protocols” as a more specifi c (procedure- or specialty-specifi c) form of practice guidelines. Clinical pathways An optimal sequencing and timing of interventions for a particular diagnosis or procedure. A “care map” or multidisciplinary action plan extends the concept of a clinical pathway by including an outcome index, which allows for the evaluation of the interventions. Clinical algorithms A more complex set of instructions containing conditional logic, usually expressed in branching trees. Information extracted from: Henning [4]. Setting up Guidelines for Local Requirements 331 How does the scientifi c evidence grade the recommendations of practice guidelines? In 1979, the Canadian Task Force on Periodic Health Examination made the fi rst eff orts to characterize the level of evidence underlying health care recommenda- tions and their strength. Since then, a wide variety of methods have been developed for “grading” the strength of the evidence on which recommendations are made. Grading methods take into account the study design, benefi ts and harms, and outcome (Canadi- an Task Force, U.S. Preventive Services Task Force, GRADE working group, SIGN method, SORT taxon- omy, etc.). A description of a strategy for grading the evidence according to the methodology of the study is described here: • Level 1: Evidence is extracted from systematic re- views of relevant controlled clinical trials (with meta-analysis when possible) Table 2 Strategies used for developing practice guidelines Strategy Description Identifi cation of a regional medical problem A regional health problem is identifi ed. Th e impact of this problem on the population and the usefulness of practice guidelines is analyzed. If needed, a consensus group for the development of guidelines (for manage- ment, care, diagnosis, etc.) is formed. Selection of a group of experts Formed by specialists from areas related to the guideline topic. Selection criteria include experience (more than 5 years) in this particular fi eld, in clinical research, in grading the evidence for recommendations, and/ or an academic profi le. Clinical practitioners recommended from the national medical associations related to this specifi c area are also included. Experts must not have any confl ict of interest. Identifying medical tendencies A questionnaire to evaluate the medical tendencies (for diagnosis, management, care, etc.) is developed by the group of experts. Items on the questionnaire are based on the statements made by other consensus groups, clinical guidelines, clinical pathways, or clinical algorithms. Results from questionnaires are sent to the se- lected experts. Review of the literature From the selected guideline topic, a focused review of the literature is made. Th is process is achieved using diverse electronic medical databases (PubMed, EMBASE, LILACS, and others). Cross-reference of selected documents is made. Resources to obtain references are provided by the national institutes of health, national medical associations, and nonprofi t organizations. Sending evidence to the selected experts Results from the review of the literature are send to the group of selected experts. Th e objective is that every participant have the opportunity to analyze the literature before the consensus meeting. Elaborating recom- mendations A consensus meeting is held to analyze the results obtained from the questionnaire and to develop specifi c recommendations (for management, diagnosis, education, care, etc.). Every recommendation is considered for further review based on the group’s expertise and the results from the review of the literature. Preliminary results From the consensus meeting a preliminary report is obtained. Each of the recommendations is submitted to a focused review of the scientifi c evidence. Meta-analysis, systematic reviews, randomized controlled trials, randomized uncontrolled trials, and case reports for each specifi c recommendation are analyzed. If there are no studies, the recommendation is “based on consensus group expertise.” Results from this search are sent to the group of experts. Grading recom- mendations Feedback from the group of experts about the evidence to endorse a recommendation is analyzed. Th e method for grading for every recommendation is described in Table 3. Preliminary practice guidelines A preliminary document is sent to the consensus group. Final notes from the participants are considered, and a fi nal document is elaborated. Review of the fi nal document Th e fi nal document is sent to the participants for approval (as many times as needed). After this process is completed, the document is sent for publication in a peer-reviewed journal. Implementation of guidelines Extensive education among clinicians, health care administrators, policy makers, benefi t managers, and patients and their families is performed in every fi liation center from each consensus participant. Conferences at regional congresses or medical meetings are provided. Local eff orts to implement guidelines require the commitment of the participants. Follow-up and evaluation of the guidelines A questionnaire designed to evaluate clinicians’ knowledge of the guidelines or their outcome is performed. Evaluation is obtained by the method developed by the AGREE Collaboration Group. Information extracted from: Frances [ref. 2], Guevara-López et al. [ref. 3]. AGREE Collaboration Group: www.agreecollaboration.org; National Institute for Health and Clinical Excellence (UK): www.nice.org.uk. 332 Uriah Guevara-Lopez and Alfredo Covarrubias-Gomez • Level 2: Evidence is extracted from one or more well-designed randomized controlled clinical trials • Level 3: Evidence is extracted from well-designed nonrandomized clinical trials or well-designed cohort studies or analytic case reports (if possible multicenter or performed at diff erent times) • Level 4: Evidence is extracted from expert opin- ions and/or opinion leaders (supported if possible by the reports from other consensus statements) Th e evidence can be converted into recommen- dations (type A, B, or C) and the “strength of evidence and maximum benefi t” (Class A to Class E), depending on how advisable the use of a specifi c treatment or in- tervention is (Class A = highly advisable and Class E = insuffi cient evidence). How are practice guidelines evaluated? Th e quality of clinical practice guidelines must be evalu- ated and diverse methods to achieve this propose have been reported. Th ere are three basic stages of evalua- tion: (i) evaluation during the development of guidelines and before their full dissemination and implementa- tion (inception evaluation); (ii) evaluation of health care programs within which guidelines play a central role (guidelines-program evaluation); and (iii) evaluation of the eff ects of guidelines within defi ned health care envi- ronments (scientifi c evaluation). Th e evaluation of PGs also includes the identi- fi cation of potential biases of guideline development, and the assurance that recommendations are valid and feasible for practice. Th is evaluation process takes into account the benefi ts, harms, and costs of the recom- mendations, as well as the practical issues attached to them. Th erefore, the assessment of PGs includes judg- ments about the methods used for its development, the content of the fi nal recommendations, and the factors linked to their uptake. How can practice guidelines be implemented? Th e fact that most PGs have been published and then forgotten has to do with the lack of eff orts for their implementation. Th e acceptance of PGs requires ex- tensive education among clinicians, health care ad- ministrators, policy makers, benefi t managers, and patients and their families. Th erefore, PGs must in- troduce a comprehensive and integrative strategy for their implementation. An implementation strategy relies on informing and educating physicians about the content of guide- lines. Impersonal approaches that use the dissemina- tion of written material alone or presentations to large audiences have not been very successful. Education of a specifi c PG must be personalized, involve respected physician leaders and incorporate a high degree of in- teraction between the target audience and those pre- senting the information. Comparison of actual performance with the per- formance that would be expected if the guidelines were followed may be used as a feedback strategy to achieve PG implementation. Feedback can occur either as the service is being provided (concurrent feedback) or after that service has been provided (retrospective feedback). A physician’s knowledge of PGs to obtain board recertifi cation has been described as an useful strategy for guideline implementation. For that reason, medical associations or medical boards should be part of PG implementation strategies. Th eir role could be to generate distance learning programs and continu- ing medical education (CME) certifi cation on the PG contents. To add (and receive) the support from health care administrators and policy makers, it is advisable to stress the economical impact of PGs (which usually attracts their attention!). Finally, education of patients and their families as well as the public about the potential benefi ts ob- tained by PG must be part of the implementation pro- cess. Th ese educational eff orts may be extended to non- governmental organizations. How do clinicians respond to practice guidelines? Th e impact of guidelines on the behavior of physicians has been poorly documented, although some reports documented a considerable disappointment with PGs. Other studies show that physicians are generally posi- tive about guidelines but that they do not integrate them into their practices to a large extent. Th e reason for this ambivalent behavior lies in problems associ- ated with their production, dissemination, and use. However, little is known about physicians’ (and pa- tients’) attitudes and suspicions toward PGs, as well as Setting up Guidelines for Local Requirements 333 regarding the motives for encouraging their use or as to their credibility. Th is has been recognized as a defi - cit, since certain motives could cause practitioners and their patients to resist PGs. Some studies indicate that the physician’s ad- herence to guidelines may be hindered by a variety of barriers. Identifi ed were: (i) awareness, (ii) familiarity, (iii) agreement, (iv) self-effi cacy, (v) outcome expec- tancy, (vi) ability to overcome the inertia of previous practice, and (vii) absence of external barriers to per- form recommendations. Another factor that may slow down adherence by physicians to PGs may be the dogmatic educational background. For example, Canadian family physicians show little resistance to guidelines and appear to need less threat of external control to incorporate them into their practice. On the other hand, American internists are less supportive of PGs. It is possible that informa- tion acquired from medical training may play a role in PG support from practitioners. Th erefore, the develop- ment of PGs must include lecturers and opinion lead- ers at medical schools and respected organizations to foster dissemination. Th e clarity and readability and the clinical ap- plicability of a guideline are other elements that con- tribute to the acceptance of guidelines by clinicians. In conclusion, PGs must be written in a user-friendly way, adapted to the practical needs of the clinician’s daily practice, and advocated thoroughly by medical boards, opinion leaders, and medical societies. If the implementation of a PG is successful, the results for patient safety are encouraging. Download 4.8 Kb. Do'stlaringiz bilan baham: |
