RESUMEN

OBJECTIVE: To establish what GIN guideline community members see as the desirable features of a guidelines library and registry of guidelines in development STUDY DESIGN AND SETTING: An explorative mixed-methods study was undertaken, including scoping activity and semi-structured interviews with guideline developers and endorsers from nine member organizations of the Guidelines International Network. RESULTS: A small number of desirable features of a guideline library were identified: comprehensiveness; single source of information to avoid searching multiple sites; inclusion of related materials; being up to date; searchability and ease of use. No existing library of guidelines was considered to have all of these features. A number of issues arose out of the desire to have a comprehensive library of guidelines, including inclusion of 'high quality guidelines' and limiting the scope to include only national guidelines. For registries of guidelines in development, the data set should be limited to avoid placing undue burden on those entering information. CONCLUSION: Our findings identify ongoing issues for the guideline community, including the tension between comprehensiveness and ease of use, which can result in limited uptake, reporting of guideline quality and the need for clarity on the purpose of any library or registry.

RESUMEN

It is unclear how best to predict peri-operative cardiovascular risk in patients with atrial fibrillation undergoing non-cardiac surgery. This study examined the accuracy of the revised cardiac risk index and three atrial fibrillation thrombo-embolic risk models for predicting 30-day cardiovascular events after non-cardiac surgery in patients with a pre-operative history of atrial fibrillation. We conducted a prospective cohort study in 28 centres from 2007 to 2013 of 40,004 patients ≥ 45 years of age undergoing inpatient non-cardiac surgery who were followed until 30 days after surgery for cardiovascular events (defined as myocardial injury, heart failure, stroke, resuscitated cardiac arrest or cardiovascular death). The 2088 patients with a pre-operative history of atrial fibrillation were at higher risk of peri-operative cardiovascular events compared with the 34,830 patients without a history of atrial fibrillation (29% vs. 13%, respectively, adjusted odds ratio 1.30 (95%CI 1.17-1.45). Compared with the revised cardiac risk index (c-index 0.60), all atrial fibrillation thrombo-embolic risk scores were significantly better at predicting peri-operative cardiovascular events: CHADS2 (c-index 0.62); CHA2 DS2 -VASc (c-index 0.63); and R2 CHADS2 (c-index 0.65), respectively. Although the three thrombo-embolic risk prediction models were significantly better than the revised cardiac risk index for prediction of peri-operative cardiovascular events, none of the four models exhibited strong discrimination metrics. There remains a need to develop a better peri-operative risk prediction model.

RESUMEN

OBJECTIVES: This study aimed to describe how colorectal practice guidelines (PGs) incorporate the patient perspective. STUDY DESIGN AND SETTING: We searched in the Guidelines International Network library, MEDLINE, National Guideline Clearinghouse, NHS Evidence database, and TRIP database. Two authors independently selected the PGs. We considered recommendations rated or worded as weak or conditional or suggesting multiple options, as potentially preference sensitive. Two authors independently evaluated if, in potentially sensitive recommendations, the patient perspective was incorporated. RESULTS: We included 28 PGs that contained 588 recommendations, being 256 potentially preference sensitive. Ten PGs (36%) included patients in the development process, and 12 (43%) provided information about patients' perspectives. Nine PGs (32%) included recommendations in which the patient perspective was explicitly considered, and 13 (46.4%) that recommended a discussion with the patient. From a total of 588 recommendations, 9.7% (25/256) of potentially preference-sensitive recommendations considered the patient perspective. The inclusion of patients in the development process was associated with a more frequent incorporation of the patient perspective in potentially preference sensitive recommendations (70% vs. 0%; P < 0.001). CONCLUSIONS: Guideline users should be aware that the incorporation of the patient perspective in colorectal cancer PGs is suboptimal. Guideline developers should make efforts to incorporate the patient perspective, especially in preference-sensitive recommendations.

RESUMEN

BACKGROUND: The optimal means of pre-operative risk stratification in patients with atrial fibrillation (AF) is uncertain. OBJECTIVE: To examine the accuracy of AF thromboembolic risk models (the CHADS2, CHA2DS2-VASc, and R2CHADS2 scores) for predicting 30-day stroke and/or all-cause mortality after non-cardiac surgery in patients with preoperative AF, and to compare these risk scores with the Revised Cardiac Risk Index (RCRI). PATIENTS/METHODS: A multicentre (8 countries, 2007-2011) prospective cohort study of patients ≥ 45 years of age undergoing inpatient non-cardiac surgery, who were followed until 30 days after surgery. We calculated c-statistics for each risk prediction model and net reclassification improvements (NRIs) compared with the RCRI. RESULTS: The 961 patients with preoperative AF were at higher risk of any cardiovascular event in the 30 days postoperatively compared with the 13 001 patients without AF: 26.6% vs. 9.0%; adjusted odds ratio, 1.58; 95% confidence interval [CI], 1.33-1.88. All thromboembolic risk scores predicted postoperative death just as well as the RCRI (with c-indices between 0.67 and 0.72). Compared with the RCRI (which had a c-index of 0.64 for 30-day stroke/death), the CHADS2 (c-index, 0.67; NRI, 0.31; 95% CI, 0.02-0.61) significantly improved postoperative stroke/mortality risk prediction, largely due to improved discrimination of patients who did not subsequently have an event. CONCLUSIONS: In AF patients, the three thromboembolic risk scores performed similarly to the RCRI in predicting death within 30 days and the CHADS2 score was the best predictor of postoperative stroke/death regardless of type of surgery.

RESUMEN

BACKGROUND: A major challenge in updating clinical guidelines is to efficiently identify new, relevant evidence. We evaluated the efficiency and feasibility of two new approaches: the development of restrictive search strategies using PubMed Clinical Queries for MEDLINE and the use of the PLUS (McMaster Premium Literature Service) database. METHODS: We evaluated a random sample of recommendations from a national guideline development program and identified the references that would potentially trigger an update (key references) using an exhaustive approach. We designed restrictive search strategies using the minimum number of Medical Subject Headings (MeSH) terms and text words required from the original exhaustive search strategies and applying broad and narrow filters. We developed PLUS search strategies, matching Medical Subject Headings (MeSH) and Systematized Nomenclature of Medicine (SNOMED) terms with guideline topics. We compared the number of key references retrieved by these approaches with those retrieved by the exhaustive approach. RESULTS: The restrictive approach retrieved 68.1 % fewer references than the exhaustive approach (12,486 versus 39,136), and identified 89.9 % (62/69) of key references and 88 % (22/25) of recommendation updates. The use of PLUS retrieved 88.5 % fewer references than the exhaustive approach (4,486 versus 39,136) and identified substantially fewer key references (18/69, 26.1 %) and fewer recommendation updates (10/25, 40 %). CONCLUSIONS: The proposed restrictive approach is a highly efficient and feasible method to identify new evidence that triggers a recommendation update. Searching only in the PLUS database proved to be a suboptimal approach and suggests the need for topic-specific tailoring.

RESUMEN

Postoperative atrial fibrillation (POAF) is the most common perioperative cardiac arrhythmia. A major risk factor for POAF is advanced age, both in non-cardiac and cardiac surgery. Following non-cardiac surgery, it is important to correct reversible conditions such as electrolytes imbalances to prevent the occurrence of POAF. Management of POAF consists of rate control and therapeutic anticoagulation if POAF persists for > 48 h and CHADS2 score > 2. After cardiac surgery, POAF affects a larger amount of patients. In addition to age, valve surgery carries the greatest risk for new AF. Rate control is the mainstay therapy in these patients. Prediction, prevention, and management of POAF should be further studied.

RESUMEN

La atención a pacientes con comorbilidad y pluripatología supone un reto para cualquier sistema sanitario. Las guías de práctica clínica (GPC) presentan limitaciones cuando se aplican a esta población. El objetivo de este trabajo es realizar una propuesta terminológica y metodológica sobre el abordaje de la comorbilidad y la pluripatología en las GPC. De acuerdo a la revisión bibliográfica efectuada, se sugieren algunas propuestas para su abordaje en las diferentes fases de elaboración de las GPC, con especial atención a la inclusión de los clusters de comorbilidad en las preguntas clínicas iniciales, la incorporación de la evidencia indirecta, el peso de la carga de gestionar la enfermedad para el paciente y su entorno en la formulación de recomendaciones, así como las estrategias de difusión e implementación. Estas propuestas deben desarrollarse en mayor profundidad con la participación de más agentes para disponer de herramientas válidas y útiles en esta población

RESUMEN

This is the third and last article in the series about the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach to grading the quality of evidence and the strength of recommendations in clinical practice guidelines and its application in the field of allergy. We describe the factors that influence the strength of recommendations about the use of diagnostic, preventive and therapeutic interventions: the balance of desirable and undesirable consequences, the quality of a body of evidence related to a decision, patients' values and preferences, and considerations of resource use. We provide examples from two recently developed guidelines in the field of allergy that applied the GRADE approach. The main advantages of this approach are the focus on patient important outcomes, explicit consideration of patients' values and preferences, the systematic approach to collecting the evidence, the clear separation of the concepts of quality of evidence and strength of recommendations, and transparent reporting of the decision process. The focus on transparency facilitates understanding and implementation and should empower patients, clinicians and other health care professionals to make informed choices.

RESUMEN

La incidencia de sobrepeso y obesidad en la infancia y adolescencia está aumentando de forma progresiva, tanto en los países industrializados como en los países en vías de desarrollo. Su prevención requiere la implicación de gobiernos e instituciones para poder llevar a cabo estrategias que permitan frenar su desarrollo. Hasta la fecha, las intervenciones preventivas que se ha mostrado más eficaces son las multidisciplinares (dirigidas a la promoción de la actividad física, al fomento de una alimentación saludable y a la disminución de hábitos sedentarios), con la implicación de la familia y orientadas a diferentes ámbitos (generalmente escolar, con apoyo en la comunidad y la familia). A menudo, están intervenciones no consiguen prevenir la obesidad, pero logran mejoras en la alimentación y una mayor realización de ejercicio físico, lo cual supone un primer paso esencial para abordar esta enfermedad que supone un grave problema de salud pública (AU)

The incidence of childhood over weight and obesity is progressively increasing, both in high income and low income countries. Its prevention requires the implication of governments and institutions to carry out some strategies to stop this development. So far, multidisciplinary interventions (i.e. those that involve physical exercise, a healthy diet and the reduction of sedentary behaviors) with the support of the family and carried our at different settings 8usually in schools, with the support of families and the community) have shown to be the most effective for the prevention of this disease. This sort of interventions is not always able to prevent obesity, but they help to improve diet and to increase physical activity, which is a first step to tackle this important public health issue (AU)
