Computer-assisted, high-frequency, hospital-wide point prevalence surveys of hospital-acquired infections in a tertiary care hospital, the Netherlands, 2013 to 2014.

ABSTRACT: BackgroundSurveillance of hospital-acquired infections (HAI) often relies on point prevalence surveys (PPS) to detect major deviations in the occurrence of HAI, supplemented with incidence measurements when more detailed information is needed. In a 1,320-bed university medical centre in the Netherlands, we evaluated an electronically assisted surveillance system based on frequently performed computer-assisted PPS (CAPPS).AimThe primary goals were to evaluate the performance of this method to detect trends and to determine how adjustments in the frequency with which the CAPPS are performed would affect this performance. A secondary goal was to evaluate the performance of the algorithm (nosocomial infection index (Nii)) used.MethodsWe analysed the data of 77 hospital-wide PPS, performed over a 2-year period (2013 and 2014) and including 25,056 patients.ResultsSix trends with statistical significance were detected. The probability to detect such trends rapidly decreased when PPS are performed at a lower frequency. The Nii and its dynamics strongly correlated with the presence of HAI.ConclusionPerforming computer-assisted, high frequency hospital-wide PPS, is a feasible method that will detect even subtle changes in HAI prevalence over time.

Project description:BackgroundHepatitis B and C are major public health threats in the World Health Organization (WHO) European Region. Viral hepatitis surveillance shortcomings have resulted in many WHO Member States having insufficient data available to guide decision-making. This study describes surveillance in the region based on a quantitative sub-analysis of findings from the 2013 WHO viral hepatitis policy report and a qualitative analysis of civil society survey responses associated with these findings.MethodsDescriptive statistics were created from information that national government focal points for viral hepatitis in 44 countries had previously reported in response to the WHO survey. Bivariate analysis was performed to compare data from within and outside of the European Union/European Economic Area (EU/EEA). Survey responses from civil society organizations in the countries of the WHO European Region were collated, and a descriptive analysis of the comments on surveillance-related questions was performed to identify key themes.ResultsThe response rate for the survey of governments was 83 % among both EU/EEA countries (25/30) and non-EU/EEA countries (19/23). More than 90 % of governments reported having national surveillance systems for the acute forms of hepatitis B and hepatitis C, but less than two-thirds reported surveillance for the chronic forms of both diseases. High proportions of governments reported having central registries for the reporting of deaths (96 %) and liver cancer cases (80 %), while less than half reported regularly conducting viral hepatitis sero-surveys. All responding Member States reported having adequate laboratory capacity nationally to support hepatitis outbreak investigations and other surveillance activities. Target populations for sero-surveys most commonly included people who inject drugs (27 %), the general population (25 %), men who have sex with men (20 %) and pregnant women (20 %). Few statistically significant differences were found between EU/EEA and non-EU/EEA countries.ConclusionsStudy findings indicated a capacity for robust viral hepatitis surveillance across the WHO European Region, with most countries having important surveillance components in place, but notable weaknesses were also identified. There is an urgent need for countries throughout the region to strengthen their surveillance programs in order to maximize the population-level impact of advances in HBV and HCV prevention and treatment.
