Prevention of nosocomial bloodstream infections in preterm infants

Protecting patients from harm is the overarching theme of the studies presented here. More precisely, this thesis places a focus on the prevention of nosocomial or hospitalacquired bloodstream infections in preterm infants, thus saving them from further harm. A nosocomial infection is an infection acquired during hospitalization 48-72 hours after admission or birth. These infections are a threat to patients’ health worldwide

Vibration therapy reduces CPAP need in a prospective randomised controlled trial

Background: Increased mucus production is a common phenomena following ventilatory support, which might increase morbidity. In order to reduce airway obstruction we tested the effect of vibration therapy on the duration of ventilatory support. Methodology: We conducted a randomised control study in a level IIIC NICU (28 beds) of a university hospital. Compared were nonactive techniques to vibration therapy in preterm infants with a gestational age of 26 - 33 weeks. All infants were ventilated or receive respiratory support by nasal CPAP. Results: 104 infants were enrolled, 49 in the vibration group and 55 in the control group. Demographic characters were in the vibration group compared to control group mean birth weight 1274 (± 335) gram vs. 1240 (± 351) gram and mean gestational age 29.8 (± 1.3) weeks vs. 29.9 (± 1.4) weeks. Vibration therapy did not reduce ventilation time (100 vs. 80 hours, p = 0.88) however duration of CPAP decreases significant (57 vs 157 hours, p < 0.018). Conclusion: Vibration therapy reduced Mean Airway Pressure, oxygen requirements and CPAP need in preterm infants, but did not reduce the duration of mechanical ventilation

Is cranial molding preventable in preterm infants? A systematic literature review of the effectiveness of interventions

Aims: A systematic review of published studies was conducted to study the evidence supporting interventions to prevent or reduce cranial molding of the preterm infant in Neonatal Intensive Care Units. Background: Incidence of cranial molding has increased over recent decades. Cranial molding is identified as a contributor for negative physical and psychosocial developmental effects. Design and Method: A systematic literature review and critical appraisal according to the Cochrane Collaboration Center assessment criteria was performed. Results: Eight intervention studies meeting the inclusion criteria were identified. Most studies used the anterior-posterior: bi-parietal ratio as measurement of cranial molding. One multicenter quasi-experimental intervention study showed that infants who received regular repositioning had a statistically significant reduction of bilateral head flattening compared to infants who did not receive this intervention. Other studies had either methodological weaknesses or showed no effect for the intervention studied. Conclusion: Evidence is poor and restricted to one intervention; regular body repositioning. More well-designed randomized studies are needed to confirm the effect of regular head and body positioning

Hand disinfection in a neonatal intensive care unit: continuous electronic monitoring over a one-year period

<p>Abstract</p> <p>Background</p> <p>Good hand hygiene compliance is essential to prevent nosocomial infections in healthcare settings. Direct observation of hand hygiene compliance is the gold standard but is time consuming. An electronic dispenser with built-in wireless recording equipment allows continuous monitoring of its usage. The purpose of this study was to monitor the use of alcohol-based hand rub dispensers with a built-in electronic counter in a neonatal intensive care unit (NICU) setting and to determine compliance with hand hygiene protocols by direct observation.</p> <p>Methods</p> <p>A one-year observational study was conducted at a 27 bed level III NICU at a university hospital. All healthcare workers employed at the NICU participated in the study. The use of bedside dispensers was continuously monitored and compliance with hand hygiene was determined by random direct observations.</p> <p>Results</p> <p>A total of 258,436 hand disinfection events were recorded; i.e. a median (interquartile range) of 697 (559–840) per day. The median (interquartile range) number of hand disinfection events performed per healthcare worker during the day, evening, and night shifts was 13.5 (10.8 - 16.7), 19.8 (16.3 - 24.1), and 16.6 (14.2 - 19.3), respectively. In 65.8% of the 1,168 observations of patient contacts requiring hand hygiene, healthcare workers fully complied with the protocol.</p> <p>Conclusions</p> <p>We conclude that the electronic devices provide useful information on frequency, time, and location of its use, and also reveal trends in hand disinfection events over time. Direct observations offer essential data on compliance with the hand hygiene protocol. In future research, data generated by the electronic devices can be supplementary used to evaluate the effectiveness of hand hygiene promotion campaigns.</p

Incubator traffic light: The development of an alcohol-based hand rub dispenser system for neonatal incubators with visual feedback to improve hand hygiene compliance

Introduction: Sustained high compliance with hand hygiene prior to patient contact in a neonatal intensive care unit (NICU) could reduce the spread of pathogens and incidence of bloodstream infections of preterm infants. These infections are associated with high mortality, morbidity and additional costs. Behaviour change interventions to promote hand hygiene, such as education, have only temporary beneficial effect on compliance. Our aim is to develop a technical intervention that supports a sustainable behaviour change for appropriate hand hygiene among NICU healthcare professionals. Methods: Students from different disciplines incrementally designed and evaluated solutions in co-creation with healthcare professionals of a NICU in a teaching hospital. Results: A prototype of the € Incubator Traffic Light' system for neonatal incubators was developed, that is, a touchless alcohol-based hand rub (ABHR) dispenser with integrated colour display and incubator door sensor with lights. The system provides visual feedback to support healthcare professionals' compliance with the prescribed 30 s drying time for ABHR. After 30 s, green lights indicate that the incubator doors may be opened. In the event that doors are opened without dispensing ABHR or earlier than 30 s, blinking orange lights and a display message urge the person to close the doors. The system documents compliance data in a web-based database. Conclusions: We developed a sophisticated technical intervention to support hand hygiene compliance. It is ready for clinical tests that should prove that the system contributes to sustainable hand hygiene compliance near neonatal incubators

Implementation of a children's hospital-wide central venous catheter insertion and maintenance bundle

Background: Central venous catheter-associated bloodstream infections in children are an increasingly recognized serious safety problem worldwide, but are often preventable. Central venous catheter bundles have proved effective to prevent such infections. Successful implementation requires changes in the hospital system as well as in healthc

Intake of own Mother's milk during the first days of life is associated with decreased morbidity and mortality in very low birth weight infants during the first 60 days of life

Background: The incidence of necrotizing enterocolitis (NEC) and possibly also of sepsis is lower in preterm infants fed their own mother's milk (hereafter 'mother's milk') compared with formula-fed infants. It is unclear whether this is caused by the protective properties of breast milk or by the absence of cow's milk. Especially in early life, mother's milk is often unavailable to preterm infants, while minimal enteral nutrition is initiated immediately. Objectives: To determine whether there is an association between intake of mother's milk during the first days of life and the combined outcome of sepsis, NEC and death over a prolonged period. Methods: Retrospective study in infants with a birth weight 50% of the total intake was mother's milk (HR = 0.37, 95% CI 0.22, 0.65). Conclusion: The type of enteral nutrition during the first 10 days of life is associated with the risk of NEC, sepsis and/or death during the first 60 days of life. Copyrigh

Development of a new therapeutic technique to direct stem cells to the infarcted heart using targeted microbubbles: StemBells

Successful stem cell therapy after acute myocardial infarction (AMI) is hindered by lack of engraftment of sufficient stem cells at the site of injury. We designed a novel technique to overcome this problem by assembling stem cell-microbubble complexes, named 'StemBells'.StemBells were assembled through binding of dual-targeted microbubbles (~ 3 μm) to adipose-derived stem cells (ASCs) via a CD90 antibody. StemBells were targeted to the infarct area
