A new system for grading recommendations in evidence based guidelines

Abstract: The Scottish Intercollegiate Guidelines Network (SIGN) develops evidence based clinical guidelines for the NHS in Scotland. The key elements of the methodology are (a) that guidelines are developed by multidisciplinary groups; (b) they are based on a systematic review of the scientific evidence; and (c) recommendations are explicitly linked to the supporting evidence and graded according to the strength of that evidence. Until recently, the system for grading guideline recommendations was based on the work of the US Agency for Healthcare Research and Quality (formerly the Agency for Health Care Policy and Research). 1 2 However, experience over more than five years of guideline development led to a growing awareness of this system's weaknesses. Firstly, the grading system was designed largely for application to questions of effectiveness, where randomised controlled trials are accepted as the most robust study design with the least risk of bias in the results. However, in many areas of medical practice randomised trials may not be practical or ethical to undertake; and for many questions other types of study design may provide the best evidence. Secondly, guideline development groups often fail to take adequate account of the methodological quality of individual studies and the overall picture presented by a body of evidence rather than individual studies or they fail to apply sufficient judgment to the overall strength of the evidence base and its applicability to the target population of the guideline. Thirdly, guideline users are often not clear about the implications of the grading system. They misinterpret the grade of recommendation as relating to its importance, rather than to the strength of the supporting evidence, and may therefore fail to give due weight to low grade recommendations. #### Summary points A revised system of determining levels of evidence and grades …

Models of job-related stress and personal achievement among consultant doctors

Abstract: The antecedents and outcomes of feelings of job-related stress and personal achievement were studied in a large sample of consultant doctors working in Scotland. In a sample of 333 doctors it was found that a tendency to use emotion-oriented coping strategies and negative appraisals of organizational changes in the practice of medicine mediated the effect of the personality dimension of Neuroticism on reported job stress. Job stress levels predicted the degree of 'burnout' experienced by doctors, i.e. their tendencies to be emotionally exhausted by their work and to dehumanize patients. Higher clinical workloads were related to higher levels of stress but also to higher feelings of personal achievement. A substantial proportion of the variance in many of the variables in the stress model was accounted for by a general tendency to experience negative emotions, closely related to Neuroticism; this general factor appeared to be similar to the recently formulated concepts of 'negative affectivity' and 'somatopsychic distress'. The personality factors of Extraversion and Conscientiousness both contributed to positive feelings of personal achievement (N = 344); the effect of Extraversion was direct, whereas the effect of Conscientiousness was mediated by a tendency to use task-oriented coping strategies. Models of the processes of stress and personal achievement were tested for acceptability using the EQS Structural Equations Program. The implications of the models for transactional theories of stress are discussed.

Cancer incidence and mortality in patients with insulin-treated diabetes: a UK cohort study

Abstract: Raised risks of several cancers have been found in patients with type II diabetes, but there are few data on cancer risk in type I diabetes. We conducted a cohort study of 28 900 UK patients with insulin-treated diabetes followed for 520 517 person-years, and compared their cancer incidence and mortality with national expectations. To analyse by diabetes type, we examined risks separately in 23 834 patients diagnosed with diabetes under the age of 30 years, who will almost all have had type I diabetes, and 5066 patients diagnosed at ages 30-49 years, who probably mainly had type II. Relative risks of cancer overall were close to unity, but ovarian cancer risk was highly significantly raised in patients with diabetes diagnosed under age 30 years (standardised incidence ratio (SIR)=2.14; 95% confidence interval (CI) 1.22-3.48; standardised mortality ratio (SMR)=2.90; 95% CI 1.45-5.19), with greatest risks for those with diabetes diagnosed at ages 10-19 years. Risks of cancer at other major sites were not substantially raised for type I patients. The excesses of obesity- and alcohol-related cancers in type II diabetes may be due to confounding rather than diabetes per se.
