Developing a model for effective leadership in healthcare: a concept mapping approach.

Purpose: Despite increasing awareness of the importance of leadership in healthcare, our understanding of the competencies of effective leadership remains limited. We used a concept mapping approach (a blend of qualitative and quantitative analysis of group processes to produce a visual composite of the group's ideas) to identify stakeholders' mental model of effective healthcare leadership, clarifying the underlying structure and importance of leadership competencies.

Methods: Literature review, focus groups, and consensus meetings were used to derive a representative set of healthcare leadership competency statements.

Improving on the diagnostic characteristics of echocardiography for pulmonary hypertension.

This retrospective study evaluated the diagnostic characteristics of a combination of echocardiographic parameters for pulmonary hypertension (PH). Right ventricular systolic pressure (RVSP) estimation by echocardiography (echo) is used to screen for PH. However, the sensitivity of this method is suboptimal.

Giant cell interstitial pneumonia associated with nitrofurantoin.

A case of giant cell interstitial pneumonia (GIF) that occurred in association with exposure to nitrofurantoin is presented. While the diagnosis of GIP is confirmed by histopathology, this diagnosis can be supported by the findings of bizarre multinucleated giant cells (MGC), elevated T lymphocytes, and a low T lymphocyte helper/suppressor ratio in the bronchoalveolar lavage fluid (BALF). Recognition of GIP as a rare manifestation of nitrofurantoin toxicity is important because prompt therapy may be associated with a favorable outcome.
