BACKGROUND: In quality improvement activities such as audit, some general practices succeed in improving care and some do not. With audit of care likely to be one of the major tools in clinical governance, it would be helpful to establish what features of primary health care teams are associated with successful audit in general practice. OBJECTIVE: The aim of the present study was to identify those features of primary health care teams that were associated with successful quality improvement during systematic audit of diabetes care. METHOD: Semi-structured tape-recorded interviews were carried out with lead GPs and practice nurses in 18 general practices in Leicestershire that had the opportunity to improve their care and had completed two data collections in a multipractice audit of diabetes care. The interviewees were asked to describe their practice's approach to audit and the transcripts were coded for common features and judged for strength of feeling by blinded independent raters. Features common to practices that had, and those that had not, managed to improve diabetes care were identified. RESULTS: Six features were identified reliably in the transcripts by blinded independent raters. Four were significantly associated with the successful improvement of care. Success was more likely in teams in which: the GP or nurse felt personally involved in the audit; they perceived their teamwork as good; they had recognized the need for systematic plans to address obstacles to quality improvement; and their teams had a positive attitude to continued monitoring of care. A positive attitude to audit and a personal interest in the disease were not associated with improvement in care. CONCLUSIONS: Success in improving diabetes care is associated with certain organizational features of primary health care teams. Experimental studies are required to determine whether the development of teamwork enables practice teams to identify and overcome systematically the obstacles to improved quality of patient care that face them.

Endothelium-derived NO is considered to be primarily an important determinant of vascular tone and platelet activity; however, the modulation of myocardial metabolism by NO may be one of its most important roles. This modulation may be critical for the regulation of tissue metabolism. Several physiological processes act in concert to make endothelial NO synthase-derived NO potentially important in the regulation of mitochondrial respiration in cardiac tissue, including (1) the nature of the capillary network in the myocardium, (2) the diffusion distance for NO, (3) the low toxicity of NO at physiological (nanomolar) concentrations, (4) the fact that low PO(2) in tissue facilitates the action of NO on cytochrome oxidase, and (5) the formation of oxygen free radicals. A decrease in NO production is involved in the pathophysiological modifications that occur in heart failure and diabetes, disease states associated with altered cardiac metabolism that contributes to the evolution of the disease process. In contrast, several drugs (eg, angiotensin-converting enzyme inhibitors, amlodipine, and statins) can restore or maintain endogenous production of NO by endothelial cells, and this mechanism may explain part of their therapeutic efficiency. Thus, the purpose of this review is to critically evaluate the role of NO in the control of mitochondrial respiration, with special emphasis on its effect on cardiac metabolism.
