Effectiveness of classroom based crew resource management training in the intensive care unit: study design of a controlled trial

<p>Abstract</p> <p>Background</p> <p>Crew resource management (CRM) has the potential to enhance patient safety in intensive care units (ICU) by improving the use of non-technical skills. However, CRM evaluation studies in health care are inconclusive with regard to the effect of this training on behaviour and organizational outcomes, due to weak study designs and the scarce use of direct observations. Therefore, the aim of this study is to determine the effectiveness and cost-effectiveness of CRM training on attitude, behaviour and organization after one year, using a multi-method approach and matched control units. The purpose of the present article is to describe the study protocol and the underlying choices of this evaluation study of CRM in the ICU in detail.</p> <p>Methods/Design</p> <p>Six ICUs participated in a paired controlled trial, with one pre-test and two post test measurements (respectively three months and one year after the training). Three ICUs were trained and compared to matched control ICUs. The 2-day classroom-based training was delivered to multidisciplinary groups. Typical CRM topics on the individual, team and organizational level were discussed, such as situational awareness, leadership and communication. All levels of Kirkpatrick's evaluation framework (reaction, learning, behaviour and organisation) were assessed using questionnaires, direct observations, interviews and routine ICU administration data.</p> <p>Discussion</p> <p>It is expected that the CRM training acts as a generic intervention that stimulates specific interventions. Besides effectiveness and cost-effectiveness, the assessment of the barriers and facilitators will provide insight in the implementation process of CRM.</p> <p>Trial registration</p> <p>Netherlands Trial Register (NTR): <a href="http://www.trialregister.nl/trialreg/admin/rctview.asp?TC=1976">NTR1976</a></p

Intestinal carriage of Staphylococcus aureus: How does its frequency compare with that of nasal carriage and what is its clinical impact?

The bacterial species Staphylococcus aureus, including its methicillin-resistant variant (MRSA), finds its primary ecological niche in the human nose, but is also able to colonize the intestines and the perineal region. Intestinal carriage has not been widely investigated despite its potential clinical impact. This review summarizes literature on the topic and sketches the current state of affairs from a microbiological and infectious diseases' perspective. Major findings are that the average reported detection rate of intestinal carriage in healthy individuals and patients is 20% for S. aureus and 9% for MRSA, which is approximately half of that for nasal carriage. Nasal carriage seems to predispose to intestinal carriage, but sole intestinal carriage occurs relatively frequently and is observed in 1 out of 3 intestinal carriers, which provides a rationale to include intestinal screening for surveillance or in outbreak settings. Colonization of the intestinal tract with S. aureus at a young age occurs at a high frequency and may affect the host's immune system. The frequency of intestinal carriage is generally underestimated and may significantly contribute to bacterial dissemination and subsequent risk of infections. Whether intestinal rather than nasal S. aureus carriage is a primary predictor for infections is still ill-defined

Extensa falha cutânea e craniana em paciente com aplasia cutis congenita Large scalp and skull defect in patient with aplasia cutis congenita

Aplasia cutis congenita (ACC) é doença rara, caracterizada pela ausência de formação completa da pele. Geralmente ocorre no couro cabeludo, na linha mediana, e apresenta-se ao nascimento como uma ferida ulcerada que pode atingir diferentes profundidades e envolver o periósteo, crânio e dura-máter. Descrevemos o caso de menina recem-nascida que apresentava fácies dismórfica com defeito no couro cabeludo que abrangia a quase totalidade da abóbada craniana e apresentava falha óssea desde a base dos ossos frontais até os occipitais e mastóides. A dura-máter estava em sua maior parte exposta, sem sinais de fissuras. Devido à raridade da ACC e ao pequeno número de pacientes nas séries publicadas na literatura a padronização do tratamento ainda é incipiente. O que existem são recomendações. Ainda são necessários estudos que abordem desde a etiologia da doença até a avaliação dos métodos de tratamento e evolução de grupos maiores de pacientes.<br>Aplasia cutis congenita is a rare condition characterized by the absence of skin layers. It is most common on the scalp, middle line, and it can be seen as a congenital ulcer involving periosteum, skull and dura. We present the case of a female newborn infant with a dysmorphic facies, a large scalp and skull defect exposing the dura. There was no cerebrospinal fluid leakage. The rarity of cases with large defects and small series reported make difficult to determinate the ideal treatment for aplasia cutis congenita. More studies are necessary to define the etiology and best management of this patients
