A model of quality assurance and quality improvement for post-graduate medical education in Europe.

BACKGROUND: The issue of quality assurance (QA) and quality improvement (QI), being the quality of medical education intimately related to the quality of the health care, is becoming of paramount importance worldwide. AIM: To describe a model of implementing a system for internal QA and QI within a post-graduate paediatric training programme based on the ISO 9001:2000 standard. METHODS: For the ISO 9001:2000 standard, the curriculum was managed as a series of interrelated processes and their level of function was monitored by ad hoc elaborated objective indicators. RESULTS: The training programme was fragmented in 19 interlinked processes, 15 related procedures and 24 working instructions. All these materials, along with the quality policy, the mission, the strategies and the values were made publicly available. Based on the measurable indicators developed to monitor some of the processes, areas of weakness of the system were objectively identified and consequently QI actions implemented. The appropriateness of all this allowed the programme to finally achieve an official ISO 9000:2001 certification. CONCLUSIONS: The application of the ISO 9001:2000 standard served to develop an internal QA and QI system and to meet most of the standards developed for QA in higher and medical education.

Urinary aquaporin 2 and calciuria correlate with the severity of enuresis in children.

This study examined the hypothesis that nocturnal enuresis might be paralleled by aquaporin 2 (AQP2) urinary excretion. Eighty children who experienced nocturnal enuresis were studied and compared with 9 healthy children. The 24-h urine samples were divided into two portions: night collections and day collections. Creatinine equivalents of urine samples from each patient were analyzed by Western blotting. AQP2 levels were semiquantified by densitometric scanning and reported as a ratio between the intensity of the signal in the day urine sample versus the night urine sample (D/N AQP2 ratio). The D/N AQP2 ratio was 0.59 +/- 0.11 (n = 9) in healthy children and increased to 1.27 +/- 0.24 (n = 10) in a subpopulation of enuretic children who had low nocturnal vasopressin levels. In enuretic children who displayed hypercalciuria and had normal vasopressin levels, the D/N AQP2 ratio was 1.05 +/- 0.27 (n = 8). These data indicate that reduced secretion of vasopressin and absorptive hypercalciuria are independently associated with an approximately twofold increase in the urinary D/N AQP2 ratio. When low nocturnal vasopressin levels were associated with hypercalciuria, a nearly threefold increase in the D/N AQP2 ratio was observed (1. 67 +/- 0.41, n = 11). In addition, in all enuretic patients tested, the urinary D/N AQP2 ratio correlates perfectly with the severity of the disorder (nocturnal polyuria). The findings reported in this article indicate that urinary AQP2 correlates with the severity of enuresis in children.
