In the Dutch surveillance for surgical site infections (SSIs), data from 70277 orthopaedic procedures with 1895 SSIs were collected between 1996 and 2003. The aims of this study were: (1) to analyse the trends in SSIs associated with Gram-positive and Gram-negative bacteria; (2) to estimate patient-related risk factors for deep and superficial SSIs after(More)
INTRODUCTION A semi-upright position in ventilated patients is recommended to prevent ventilator-associated pneumonia (VAP) and is one of the components in the Ventilator Bundle of the Institute for Health Care Improvement. This recommendation, however, is not an evidence-based one. METHODS A systematic review on the benefits and disadvantages of(More)
The PREZIES national network for the surveillance of nosocomial infections (NI) in The Netherlands has organised a national prevalence study twice a year since 2007. This paper presents the results of the first four surveys. Of 95 hospitals in The Netherlands, 41 participated in 92 surveys and 26 937 patients were included. On the survey day 6.2% had an NI(More)
OBJECTIVES Misuse of antibiotics in surgical prophylaxis is still quite common. The objectives of this study were to reduce the quantity and improve the quality of surgical prophylaxis and to reduce costs. METHODS Prospective multi-site study of elective procedures in 13 Dutch hospitals. The quality of prophylaxis was audited before and after an(More)
Abstract Objective. Review of the literature concerning pressure ulcers in the intensive care setting. Data source and study selections. Computerized databases (Medline from 1980 until 1999 and CINAHL from 1982 until 1999). The indexing terms for article retrieval were: "pressure ulcers", "pressure sores", "decubitus", and "intensive care". Nineteen(More)
OBJECTIVE To develop prognostic models for improved risk adjustment in surgical site infection surveillance for 5 surgical procedures and to compare these models with the National Nosocomial Infection Surveillance system (NNIS) risk index. DESIGN In a multicenter cohort study, prospective assessment of surgical site infection and risk factors was(More)
OBJECTIVE To compare the number of surgical site infections (SSIs) registered after hospital discharge with respect to various surgical procedures and to identify the procedures for which postdischarge surveillance (PDS) is most important. DESIGN Prospective SSI surveillance with voluntary PDS. Recommended methods for PDS in the Dutch national nosocomial(More)
The use of femoral artery closure devices to obtain hemostasis after percutaneous catheterization has become widespread because of their proven feasibility in combination with patient-related advantages. Since 2002 more than 6,500 patients have undergone either diagnostic angiography or therapeutic intervention via the femoral route with an Angioseal(More)
To examine the incidence of and risk factors for device-associated infections and associated mortality. Prospective surveillance-based study in ICUs of 19 hospitals in The Netherlands. The study included 2,644 patients without infection at admission during 1997–2000, staying in the ICU for at least 48 h. The occurrence of ventilator-associated pneumonia(More)
A surveillance programme was started after a period of high infection rates in an orthopaedic surgical department. The programme was aimed at reducing infection rates in elective hip and knee replacement procedures, and at creating awareness of infection control practices in an acute hospital. Possible causes of the initial high infection rates were(More)
