Nonpurulent cellulitis is an acute bacterial infection of the dermal and subdermal tissues that is not associated with purulent drainage, discharge or abscess. The objectives of this systematic review and meta-analysis were to identify and appraise all controlled observational studies that have examined risk factors for the development of nonpurulent cellulitis of the leg (NPLC). A systematic literature search of electronic databases and grey literature sources was performed in July 2015. The Newcastle-Ottawa Scale (NOS) was used to assess methodological quality of included studies. Of 3059 potentially eligible studies retrieved and screened, six case-control studies were included. An increased risk of developing NPLC was associated with previous cellulitis [odds ratio (OR) 40·3, 95% confidence interval (CI) 22·6-72·0], wound (OR 19·1, 95% CI 9·1-40·0), current leg ulcers (OR 13·7, 95% CI 7·9-23·6), lymphoedema/chronic leg oedema (OR 6·8, 95% CI 3·5-13·3), excoriating skin diseases (OR 4·4, 95% CI 2·7-7·1), tinea pedis (OR 3·2, 95% CI 1·9-5·3) and body mass index > 30 kg m (OR 2·4, 95% CI 1·4-4·0). Diabetes, smoking and alcohol consumption were not associated with NPLC. Although diabetics may have been underrepresented in the included studies, local risk factors appear to play a more significant role in the development of NPLC than do systemic risk factors. Clinicians should consider the treatment of modifiable risk factors including leg oedema, wounds, ulcers, areas of skin breakdown and toe-web intertrigo while administering antibiotic treatment for NPLC.
Diagnostic imaging is integral to the evaluation of many emergency department (ED) patients. However, relatively little effort has been devoted to patient-centered outcomes research (PCOR) in emergency diagnostic imaging. This article provides background on this topic and the conclusions of the 2015 Academic Emergency Medicine consensus conference PCOR work group regarding "Diagnostic Imaging in the Emergency Department: A Research Agenda to Optimize Utilization." The goal was to determine a prioritized research agenda to establish which outcomes related to emergency diagnostic imaging are most important to patients, caregivers, and other key stakeholders and which methods will most optimally engage patients in the decision to undergo imaging. Case vignettes are used to emphasize these concepts as they relate to a patient's decision to seek care at an ED and the care received there. The authors discuss applicable research methods and approaches such as shared decision-making that could facilitate better integration of patient-centered outcomes and patient-reported outcomes into decisions regarding emergency diagnostic imaging. Finally, based on a modified Delphi process involving members of the PCOR work group, prioritized research questions are proposed to advance the science of patient-centered outcomes in ED diagnostic imaging.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
