Communication techniques were found to have a clinically relevant impact on body pain. This finding, together with a trend towards better scores in the remaining scales, justifies the use of these techniques in psychosocial interventions delivered to patients with medically unexplained symptoms.

We evaluated tele-ophthalmology for diabetic retinopathy screening in a primary care setting. Four general practitioners (GPs) were taught to assess non-mydriatic retinography images of patients with diabetes. After training, a total of 1223 patients were screened using this method: 926 (76%) did not have diabetic retinopathy and 297 (24%) were referred for an ophthalmologic assessment. Of the 297 patients, 186 (15%) did not have diabetic retinopathy and were considered to be false positives, 85 (7%) had diabetic retinopathy and in 26 cases (2%) the retinography images were unreadable. The specificity of GPs for detecting diabetic retinopathy by non-mydriatic retinography was 83%. Ophthalmologists also assessed 120 patients who had been diagnosed as normal to detect false negatives. Ten patients (8.3%) had mild non-proliferative diabetic retinopathy with small isolated retinal hemorrhages. Only one patient (0.8%) had treatable diabetic retinopathy with hard exudates and microaneurysms. The sensitivity of GPs for detecting diabetic retinopathy was 90.9%; the sensitivity for detecting treatable lesions was 99.2%. We concluded that adequately trained GPs can screen for treatable lesions of diabetic retinopathy with a very high level of reliability using non-mydriatic retinography.

These results depict an extremely difficult scenario for dichotomous diagnostic strategies aimed at classifying patients' symptoms as either organic or functional. Rather than struggling to choose one of these hypotheses, it is suggested that both of them should always be addressed concurrently.

BackgroundClinical guidelines (CGs) are popular for healthcare decision making but their acceptability and use by healthcare providers is influenced by numerous factors. Some of these factors are professional-related, such as knowledge and perceptions of and attitudes toward CGs in general. The aim of our study was to evaluate attitudes and perceptions of Spanish physicians towards CGs.MethodsWe coordinated six discussion groups with a total of 46 physicians. The participants were drawn from 12 medical specialties from both specialized and primary care. We recorded the sessions and transcribed the content verbatim. We analyzed the data using an approach based on the grounded theory.ResultsWe identified two main constructs that defined the physicians' perceptions towards guidelines: knowledge and usefulness. “Knowledge” defined the theoretical meanings of guidelines, while “Usefulness” referred to the pragmatic approach to guidelines. These constructs were interrelated through a series of categories such as confidence, usability, accessibility, dissemination and formats.ConclusionsIn our study, the constructs that impacted most on physician's attitudes to clinical guidelines were knowledge and usefulness. The tension between the theoretical and the pragmatic constructs determined the attitudes and how physicians use guidelines. Groups developing guidelines should ask relevant clinical questions and develop implementable and context specific recommendations. Developers should be explicit and consistent in the development and presentation of recommendations.
