The care of preterm infants with birth weight below 1250 g: risk-adjusted quality benchmarking as part of validating a caseload-based management system.

BACKGROUND: In Germany, controversy currently surrounds the contention that the quality of care for preterm infants weighing less than 1250 g is best assured by requiring that centers treat a minimum of 30 such cases per year. METHODS: A risk-adjusted model was developed on the basis of neonatal data from 7405 preterm infants treated in German centers, and the effect of caseload on risk-adjusted mortality was analyzed. In addition, the discriminative ability of the minimal caseload requirement for quality assessment was studied. The authors designate the quality of care in a particular center as above average if the observed mortality is lower than would have been expected from the risk profile of the preterm infants treated there. RESULTS: Risk-adjusted mortality was found to be significantly higher in smaller centers (those with fewer than 30 cases per year) than in larger ones (odds ratio, 1.34). Even among centers whose caseload exceeded the minimum requirement, there was still marked variability in risk-adjusted mortality (range: 3.5% to 28.6%). Of all the preterm infants treated in larger centers, 56% were treated in centers with above-average quality of care. 44% of the centers with above-average quality of care had caseloads in the range of 14 to 29 cases per year. CONCLUSION: Because of the marked variability in risk-adjusted mortality, even among larger centers, a caseload of 30 or more cases per year is not a suitable indicator of the quality of care. The neonatal data of external quality assurance should be used to develop an instrument for quality-based coordination of care that takes not just morbidity and mortality, but also the treating centers' competence profiles into account.

[Wound management in patients with chronic wounds in ambulatory nursing--a pilot study]. / Die Wundversorgung von Menschen mit chronischen Wunden in der ambulanten Pflege--Pilotstudie.

Currently relevant data about prevalence of chronic wounds and wound management in home care nursing services are not available for Germany. In this study 38 home care nursing services were surveyed by means of a questionnaire. Response rate was 61%. Results showed that almost 9% of the home care nursing services treated patients suffering from chronic wounds. The most common wound was the pressure ulcer with a prevalence of 4.1%, followed by leg ulcer (2.7%) and the diabetic foot (1%). The questionnaire about wound management was completed for 47 patients of 24 home care services. 29 of the patients were females and 18 males. The average age of the patients was 78 years. Important diagnostic information about the nature and the recurrence rate of the wounds was not available to the nursing staff. The average time that a wound existed was 6.7 years with a range of 3 weeks to 45 years. 87% of the patients had their wound dressings on a daily basis. The average time needed for wound dressing was 17 minutes. Wound management often occurred in a idiosyncratic way and did not always follow evidence based practice. Wound management can be significantly improved by the use of modern wound dressing, reduction of the frequency of wound dressings, standardized wound documentation and better co-operation with doctors, nursing experts and health insurance organisations. Basis on the convenience nature of the sample results of this survey should be generalized and interpreted with caution. This study gives clear indications of the significance of the problem. More studies with representative samples are needed.
