To test the feasibility of classifying emergency department patients into severity grades using data mining methods. ⋯ It is possible to produce a computerized classification model for the severity grade of triage patients, using data mining methods. Learning from patient records regarding which there is a consensus of several physicians is preferable to learning from each physician's patients. Either Naïve Bayes or C4.5 can be used; Naïve Bayes is preferable for unbalanced data sets. An ambiguity in the intermediate severity grades seems to hamper both the physicians' agreement and the classifiers' accuracy.

Adverse events are unintended patient injuries or complications that arise from health care management resulting in death, disability or prolonged hospital stay. Adverse events that require critical care are a considerable financial burden to the health care system, but also their global impact on patients and society is probably underestimated. The objectives of this systematic review were to synthesize the best available evidence regarding the estimates of the incidence and preventability of adverse events that necessitate intensive care admission, to determine the type and consequences [mortality, length of intensive care unit (ICU) stay and costs] of these adverse events. ⋯ Adverse events are an important reason for (re)admission to the ICU and a considerable proportion of these are preventable. It was not possible to estimate an overall incidence and preventability rate of these events as we found considerable heterogeneity. To decrease adverse events that necessitate ICU admission, several systems are recommended such as early detection of patients with clinical instability on general wards and the implementation of rapid response teams. Step-down or intermediate care units could be a useful strategy for patients who require monitoring to avoid ICU readmissions. However, the effectiveness of such systems needs to be investigated.

The aim of this study was to explore patients' beliefs about medicines by administering the German version of the Beliefs about Medicines Questionnaire (BMQ) in a primary care setting among chronically ill patients and to examine its psychometric properties. The BMQ assesses patients' beliefs about their individual prescribed medication as well as their beliefs about medicines in general. ⋯ The BMQ is a suitable instrument to measure patients' beliefs in medicines in German primary care settings. Most patients in our sample had positive beliefs concerning the necessity of their medication. Their levels of concern were associated with higher non-adherence.

Little is known about the quality of occupational health care provided to National Health Service (NHS) staff. We designed the first national clinical audits of occupational health care in England. We chose to audit depression and back pain as health care workers have high levels of both conditions compared with other employment sectors. The aim of the audits was to drive up quality of care for staff with these conditions. The object of this paper is to describe how we developed an audit methodology and overcame challenges presented by the organization and delivery of occupational health care for NHS staff. ⋯ Clinical audit can be conducted successfully in the occupational health setting. We obtained meaningful data that have stimulated local and national quality improvement activities. Our methodology would be transferable to occupational health settings outside the NHS and in other countries.

In 2009, the UK Department of Health formalized recommended National Health Service practices for the management of tinnitus from primary care onwards. It is timely therefore to evaluate the perceived practicality, utility and impact of those guidelines in the context of current practice. ⋯ While the lack of standardized practice might provide flexibility to meet local demand, it has drawbacks. It makes it difficult to ascertain key standards of best practice, it complicates the process of clinical audit, it implies unequal patient access to care, and it limits the implementation of translational research outcomes. We recommend that core elements of practice should be standardized, including use of a validated tinnitus questionnaires and an agreed pathway for decision making to better understand the rationale for management strategies offered.
