Use of ventilator utilization ratio for stratifying alcohol-based hand-rub consumption data to improve surveillance on intensive care units.

BACKGROUND: Germany has established a nationwide surveillance system of alcohol-based hand-rub consumption (AHC) per patient-day in hospital settings as a surrogate parameter for hand hygiene (HH) compliance. Analysis of AHC data in intensive care units (ICUs) shows not only a wide range of consumption between units of different specialties, but also within units of one specialty. This seems to reflect variation in the number of HH opportunities per patient-day between ICUs due to variation in complexity of care. AIM: To investigate whether ventilator utilization ratio (VUR) might be a good surrogate for describing complexity and intensity of care on ICUs and whether stratification by VUR works as a new method of setting benchmarks for AHC data. METHODS: Data from 365 ICUs participating in the German national nosocomial infection surveillance system (KISS) were used. VUR was calculated by dividing the number of ventilator-days per unit by the number of patient-days per unit. AHC was stratified according to VUR in quartiles. FINDINGS: The median AHC was 107mL/patient-day [interquartile range (IQR): 86-134] and the median VUR was 33% (IQR: 22-45%). The Spearman rank correlation coefficient was 0.28 (P<0.0001). After stratifying AHC according to VUR, the AHC in quartile I was significantly lower compared to quartile IV. There was also significant difference between quartile I and quartiles II and III. CONCLUSION: Stratification of AHC data according to VUR is suggested to improve the quality of benchmark parameters based on AHC data as surrogate parameter for HH compliance in ICUs.

Compliance with hand hygiene: reference data from the national hand hygiene campaign in Germany.

Hand hygiene is a key measure to prevent healthcare-associated infection. To promote hand hygiene nationally the German campaign 'Aktion Saubere Hände' was launched in January 2008, based on the World Health Organization's 'Clean Care is Safer Care' initiative. We report the first results from a full year of data collection on hand hygiene compliance recorded with the help of a renewed observation tool. Data were based on submissions from 109 participating hospitals collected from 576 wards between January 1st and December 31st, 2014. The overall median compliance was 73%, ranging from 55% (10th percentile) to 89% (90th percentile). The results demonstrated only small differences between adult and non-adult intensive care units (ICUs) with neonatal ICUs and paediatric non-ICUs maintaining higher compliance than adult care units. Performance among nurses was better than physicians, and overall rates of hand hygiene performance were significantly higher after patient contact than before.

Three years of national hand hygiene campaign in Germany: what are the key conclusions for clinical practice?

The World Health Organization (WHO) started the 'Clean Care is Safer Care' campaign in 2005. Since then, more than 120 countries have pledged to improve hand hygiene as a keystone of their national or subnational healthcare-associated infection prevention programmes. Thirty-eight countries have implemented national campaigns. Germany started a national campaign to improve hand hygiene compliance on 1 January 2008. The campaign, 'AKTION Saubere Hände', is funded by the German Ministry of Health and was initiated by the National Reference Centre for the Surveillance of Nosocomial Infections, the Society for Quality Management in Health Care and the German Coalition for Patient Safety. The campaign is designed as a multi-modal campaign based on the WHO implementation strategy. Since the end of 2010, more than 700 healthcare institutions have been actively participating in the campaign, among which are 28 university hospitals. Voluntarily participating hospitals have to implement the following measures: active support by hospital administrators of local campaign implementation, participation in a one-day introductory course, education of healthcare workers at least once a year, measurement of alcohol-based hand-rub consumption (AHC) and feedback on resulting data, implementation of the WHO 'My Five Moments for Hand Hygiene' model, increase in hand-rub availability, participation in national hand hygiene day at least every two years, and participation in national campaign network workshops at least once every two years. Observational studies to measure hand hygiene compliance are optional. Overall, there has been a significant increase of 11% in hand hygiene compliance in 62 hospitals that observed compliance before and after intervention. A total of 129 hospitals provided AHC data for three years and achieved an overall increase of 30.7%. The availability of alcohol-based hand rub increased from 86.8% to > 100% in intensive care units and from 63.6% to 91.3% in non-intensive care units. Overall, the implementation of a national campaign using the WHO multi-modal intervention strategy has led to improved hand hygiene compliance and hand-rub availability in participating settings.

Timely MMR vaccination in infancy: influence of attitudes and medical advice on the willingness to vaccinate.

In light of the failure to eliminate measles by 2010, the closure of any gaps in immunisation coverage is of paramount importance to interrupt transmission and to protect vulnerable individuals. Not only vaccination-critical attitudes of parents but furthermore the medical advice by physician in charge influence the vaccine uptake. 3 groups of factors which potentially influence parental decisions on child vaccination were analysed by univariable and multivariable logistic regression for the timely uptake of the first and the second dose of measles vaccination: parents' attitudes towards immunization, the influence of medical and laypersons and the influence of the advice of a medical doctor. A total of 3 041 children were eligible for the analysis. 53.0% of these received the first and 42.9% the second MMR dose in time. If parents considered that vaccinations are important and protective as well as the consulted physician advices towards vaccinations, children had significantly higher chances of a timely vaccination. Whereas, if parents were afraid of vaccinations or get advised by an alternative practitioner, the children had lower chances of being vaccinated in time. If medical providers help parents to reduce uncertainties about vaccination the chance for children to be vaccinated in time increased. It appeared that there still are unmet information needs after the medical consultation. By and large the medical advice plays an important role for vaccination uptake and its timing. In order to raise the vaccination rates further target-population specific approaches are needed.

[Risk factors for delayed or missed measles vaccination in young children]. / Risikofaktoren für eine verspätete oder nicht erfolgte Masernimpfung bei Kleinkindern.

Because of low measles vaccine coverage rates, measles outbreaks have been observed several times during recent years in Germany. The aim of this study is to identify parents' attitudes and beliefs towards immunisations and socio-economic factors which are associated with delayed or missed first measles vaccination in young children. We used data from a representative German-wide immunisation survey on 2116 children born between 1 January 2002 and December 2004 by collecting precise vaccination information from vaccination cards. The influence of socio-economic determinants and parental attitudes towards immunisations on the timing of the first measles dose was analysed by using multivariable Cox regression. Of these children 46.8% (95% CI: 44.5-49.1) received their first measles dose according to the recommendations of the standing committee on vaccination (STIKO) by month 15. In multivariable analysis, fathers aged 28-33 years and birth order as well as parents' belief in homeopathy and other parental attitudes indicating lack of knowledge about the importance of vaccinations significantly influenced an early immunisation. Not general opposition, but insufficient parental knowledge about the harmfulness of measles infection seemed to be responsible for the low measles vaccination rates.

[Evaluation of a pilot study on measles vaccination in Bavarian preschool children]. / Evaluation einer Pilotstudie zu Masern-Impfraten in bayerischen Kindergärten.

Several areas of Bavaria show measles vaccination coverage in preschool children below 95%. Repeated outbreaks could be attributed to this situation. A recollection model in nurseries was tested in order to document the vaccination rate in this age group and to measure the percentage of vaccinations due to intervention. Parents of new entrants to nurseries in a randomly selected rural district were asked to provide measles vaccination records of their kids and to fill in a questionnaire. 121 out of 144 vaccination records (85%) documented a complete immunisation status for measles. 12 children had not been vaccinated against measles, 10 children had received one vaccination. Eight out of these 22 children obtained supplementary measles immunisation at the time of ascertainment. The results provided are of limited statistical significance due to the small sample size. Further intervention studies have to be conducted and should even include measures supported by legal regulations.
