Pediatric invasive device utility and harm: a multi-site point prevalence survey

BACKGROUND AND AIMS

Invasive devices are widely used in healthcare settings; however, pediatric patients are especially vulnerable to invasive device-associated harm. This study aimed to explore invasive device utility, prevalence, harm, and clinical practice across three Australian pediatric tertiary hospitals.

METHODS

In 2022-2023, a multi-center, observational, rolling-point-prevalence survey was conducted. Fifty-per-cent of inpatients were systemically sampled by random allocation. Patients with devices were then followed for up to 3-days for device-related complications/failures and management/removal characteristics.

RESULTS

Of the 285 patients audited, 78.2% had an invasive device (n = 412 devices), with a median of 1 device-per-patient (interquartile range 1-2), with a maximum of 13 devices-per-patient. Over half of devices were vascular access devices (n = 223; 54.1%), followed by gastrointestinal devices (n = 112; 27.2%). The point-prevalence of all device complications on Day 0 was 10.7% (44/412 devices) and period-prevalence throughout the audit period was 27.7% (114/412 devices). The period-prevalence of device failure was 13.4% (55/412 devices).

CONCLUSIONS

The study highlighted a high prevalence of invasive devices among hospitalized patients. One-in-ten devices failed during the audit period. These findings underscore the need for vigilant monitoring and improved strategies to minimize complications and enhance the safety of invasive devices in pediatric hospital settings.

IMPACT

A high prevalence of invasive devices among hospitalized patients was reported. Of the 285 patients audited, almost 80% had an invasive device (total 412 devices), with a median of 1 device-per-patient and a maximum of 13 devices-per-patient. The most common devices used in pediatric healthcare are vascular access devices (n = 223; 54.1%), however, 16% (n = 36) of these devices failed, and one-third had complications. The point prevalence of all device complications at day 0 was 10.7% (44 out of 412 devices), with a period prevalence of 27.7% (114 out of 412 devices) throughout the audit period.

Goals of the Morbidity and Mortality meeting in acute care: A scoping review

OBJECTIVE

The objective of this study was to describe what is known about understandings of the goals of the Morbidity and Mortality meeting.

REVIEW METHODS USED

The study utilised scoping review methodology.

DATA SOURCES

Papers in English presenting empirical data published in academic journals with Morbidity and Mortality meetings as the central concept of study. Included papers presented data about the perception of stakeholders about goals of the Morbidity and Mortality meeting. Medline, Embase, and CINAHL databases were search conducted from earliest record - October 20th 2021. A manual search of the reference lists of all included papers identified further eligible papers.

REVIEW METHODS

Data about the location, participant type, and methods/ methodology were extracted and entered onto a database. Content analysis of the results and discussion sections of qualitative papers yielded broad categories of meeting goal. This provided a framework for the organisation of the quantitative findings, which were subsequently extracted and charted under these categories.

RESULTS

Twenty-five papers were included in the review, and six main categories were identified in the qualitative synthesis of findings. These included meeting goals related to quality and safety, education, legal and reputational risk management, professional culture, family/caregivers, and peer support.

CONCLUSIONS

There are heterogeneous understandings of key terminologies used to describe Morbidity and Mortality meeting goals, particularly evident within understandings of educational and quality and safety meeting goals. This paper defines and unravels this complexity in a way that researchers and clinicians can define, compare and evaluate their own department's meeting goals.

Educational strategies in the health professions to mitigate cognitive and implicit bias impact on decision making: a scoping review

BACKGROUND

Cognitive and implicit biases negatively impact clinicians' decision-making capacity and can have devastating consequences for safe, effective, and equitable healthcare provision. Internationally, health care clinicians play a critical role in identifying and overcoming these biases. To be workforce ready, it is important that educators proactively prepare all pre-registration healthcare students for real world practice. However, it is unknown how and to what extent health professional educators incorporate bias training into curricula. To address this gap, this scoping review aims to explore what approaches to teaching cognitive and implicit bias, for entry to practice students, have been studied, and what are the evidence gaps that remain.

METHODS

This scoping review was guided by the Joanna Briggs Institute (JBI) methodology. Databases were searched in May 2022 and included CINAHL, Cochrane, JBI, Medline, ERIC, Embase, and PsycINFO. The Population, Concept and Context framework was used to guide keyword and index terms used for search criteria and data extraction by two independent reviewers. Quantitative and qualitative studies published in English exploring pedagogical approaches and/or educational techniques, strategies, teaching tools to reduce the influence of bias in health clinicians' decision making were sought to be included in this review. Results are presented numerically and thematically in a table accompanied by a narrative summary.

RESULTS

Of the 732 articles identified, 13 met the aim of this study. Most publications originated from the United States (n=9). Educational practice in medicine accounted for most studies (n=8), followed by nursing and midwifery (n=2). A guiding philosophy or conceptual framework for content development was not indicated in most papers. Educational content was mainly provided via face-to-face (lecture/tutorial) delivery (n=10). Reflection was the most common strategy used for assessment of learning (n=6). Cognitive biases were mainly taught in a single session (n=5); implicit biases were taught via a mix of single (n=4) and multiple sessions (n=4).

CONCLUSIONS

A range of pedagogical strategies were employed; most commonly, these were face-to-face, class-based activities such as lectures and tutorials. Assessments of student learning were primarily based on tests and personal reflection. There was limited use of real-world settings to educate students about or build skills in biases and their mitigation. There may be a valuable opportunity in exploring approaches to building these skills in the real-world settings that will be the workplaces of our future healthcare workers.

Exploring the impact of the COVID-19 environment on nursing delivery of family-centred care in a paediatric hospital

AIMS AND OBJECTIVES

To understand how the pandemic environment impacted the delivery of FCC of children and families from a nursing perspective in a major tertiary paediatric hospital.

BACKGROUND

Family-centred care (FCC) is a well-established framework to promote parental involvement in every aspect of a child's hospitalization, however, rules and restrictions in place during the COVID-19 pandemic affected the ways in which Family-centred Care could be delivered in practice.

DESIGN

This is a qualitative exploratory descriptive study to elicit the perspective of paediatric nurses delivering care to children in a hospital during the COVID-19 pandemic in Victoria, Australia.

METHODS

Nurses from all subspecialties in a tertiary paediatric hospital were invited to participate in virtual focus groups to discuss their experience of delivering FCC during the COVID-19 pandemic. Focus groups were recorded and transcribed, then analysed using Framework Analysis.

RESULTS

Nineteen nurses participated across seven focus groups during June and July 2020. The four themes-Advocating with empathy, Enabling communication, Responding with flexibility, and Balancing competing considerations-and the eight subthemes that were generated, outline how nurses deliver FCC, and how these FCC actions were impacted by the COVID-19 environment and the related hospital restrictions.

CONCLUSION

This study documents the experiences, resilience and resourcefulness of paediatric nurses in Australia during the COVID-19 pandemic as well as moving Family-centred Care from a theoretical framework into a practical reality.

IMPACT

The findings from this study should inform consideration of the impacts of public health policies during infectious disease outbreaks moving forward. In addition by describing the core actions of Family-centred Care, this study has implications for educational interventions on how to translate FCC theory into practice. No public or patient contribution as this study explored nursing perceptions only.

Risk factors for healthcare-associated infection among children in a low-and middle-income country

BACKGROUND

Healthcare-associated infections (HAI) are one of significant causes of morbidity and mortality. Evaluating risk factors associated with HAI are important to improve clinical outcomes. We aimed to evaluate the risk factors of HAI in children in a low-to middle-income country.

METHODS

A prospective cohort study was conducted during 43 months at a teaching hospital in Yogyakarta, Indonesia. All consecutive patients admitted to pediatric ICU and pediatric wards > 48 h were eligible. Those eligible patients were observed daily to identify the presence of HAI based on CDC criteria. The risk factors of HAI were identified. Multivariable logistic regression was used to identify independent risk factors.

RESULTS

Total of 2612 patients were recruited. Of 467 were diagnosed as HAI. The cumulative incidence of HAI was 17.9%. In the multivariable analysis; length of stay > 7 days, severe sepsis, use of urine catheter, central venous catheter (CVC), non-standardized antibiotics, and aged < 1 year were independently associated with increased risk of HAI with adjusted OR (95%CI): 5.6 (4.3-7.3), 1.9 (1.3-2.9), 1.9 (1.3-2.6), 1.8 (1.1-2.9), 1.6 (1.2-2.0), and 1.4 (1.1-1.8), respectively.

CONCLUSIONS

This study found that length of stay > 7 days, use of urine catheter and CVC, non-standardized antibiotic use, aged < 1 year, and had a diagnosis of severe sepsis increased risk of HAI.

The clinical utility of the pain assessment tool in ventilated, sedated, and muscle-relaxed neonates

BACKGROUND

The neonatal Pain Assessment Tool (PAT) is considered a reliable and valid tool for assessing neonatal pain. No research has been conducted on the clinical utility of the PAT when assessing pain in ventilated, sedated, and muscle-relaxed neonates.

OBJECTIVE

The objective of the study was to determine the clinical utility of the PAT when assessing pain in ventilated, sedated, and muscle-relaxed neonates.

METHODS

Neonatal nurses from the Royal Children's Hospital completed online surveys to assess the clinical utility of the PAT. Three focus groups were then conducted to further explore the variation of pain scores from the survey and clarify the challenges in interpreting the pain score.

RESULTS

Nurses perceived the PAT clinically useful in neonates who were ventilated and minimally sedated. However, the PAT was not clinically useful in neonates who were ventilated and heavily sedated or muscle-relaxed. Further exploration via focus groups highlighted two themes related to the 'variation in the timing of the pain score' and the 'integration of critical thinking and judgement' used when assessing pain in neonates.

CONCLUSIONS

The clinical utility of the PAT is acceptable for minimally sedated neonates; however, it decreases the more sedated a neonate becomes, and the PAT's usefulness is extremely poor in the muscle-relaxed neonate. A better understanding of the timing and interpretation of the pain score in relation to the neonate's clinical status may enable improved decision-making and pain management. The PAT requires further validity, reliability, and clinical utility research, particularly in critically ill and muscle-relaxed neonates.

Predictors of mortality in children with nosocomial bloodstream infection

Background: Nosocomial bloodstream infection (BSI) is associated with high mortality rates. Evaluating factors to predict mortality is important for prevention and improving clinical outcomes. Aim: To evaluate the clinical predictors of mortality in paediatric nosocomial bloodstream infection. Methods: A prospective cohort study was conducted from 1 December 2010 until 28 February 2013 in a teaching hospital in Yogyakarta, Indonesia. All patients admitted consecutively to the paediatric ICU (PICU) and paediatric wards after > 48 h of hospitalisation were eligible. Patients were observed daily to identify the presence of nosocomial BSI based on Centers for Disease Control and Prevention (CDC) criteria. Patients were followed up until they were discharged or died, and predictors of mortality were identified. Logistic regression was used to identify independent predictors. Results: A total of 2646 patients were recruited, 170 developed nosocomial BSI (6.4%) and 70 of these children died (case fatality rate 41%). Nosocomial BSI was associated with increased mortality with an adjusted OR of 8.5 (95% CI 6.0-12.1). In multivariate analysis, malnutrition, admission to the PICU and use of a central line catheter were independently associated with an increased risk of death with adjusted ORs (95% CI), respectively, of 6.0 (1.6-22.6), 3.2 (1.6-6.7) and 3.1 (1.1-8.7). Conclusion: The study demonstrates that significant mortality is attributable to nosocomial bloodstream infection. An increased risk of death in children with nosocomial BSI can be identified by simple clinical predictors including malnutrition, admission to the PICU and use of a central line catheter.

Medication error trends and effects of person-related, environment-related and communication-related factors on medication errors in a paediatric hospital

AIM

This study aimed to examine reported medication error trends in an Australian paediatric hospital over a 5-year period and to determine the effects of person-related, environment-related and communication-related factors on the severity of medication outcomes. In particular, the focus was on the influence of changes to a hospital site and structure on the severity of medication errors.

METHODS

A retrospective clinical audit was undertaken over a 5-year period of paediatric medication errors submitted to an online voluntary reporting system of an Australian, tertiary, public teaching paediatric hospital. All medication errors submitted to the online system between 1 July 2010 and 30 June 2015 were included.

RESULTS

A total of 3340 medication errors was reported, which corresponded to 0.56% medication errors per combined admissions and presentations or 5.73 medication errors per 1000 bed days. The most common patient outcomes related to errors requiring monitoring or an intervention to ensure no harm occurred (n = 1631, 48.8%). A new hospital site and structure had 0.354 reduced odds of producing medication errors causing possible or probable harm (95% confidence interval 0.298-0.421, P < 0.0001). Patient and family involvement had 1.270 increased odds of identifying medication errors associated with possible or probable harm compared with those causing no harm (95% confidence interval 1.028-1.568, P = 0.027). Interrupted time series analyses showed that moving to a new hospital site and structure was associated with a reduction in reported medication errors.

CONCLUSION

Encouraging child and family involvement, facilitating hospital redesign and improving communication could help to reduce the harm associated with medication errors.

True Pathogen or Contamination: Validation of Blood Cultures for the Diagnosis of Nosocomial Infections in a Developing Country

BACKGROUND

Blood culture results are frequently used to guide antibiotic decision-making, but culture contaminants need to be distinguished from true pathogens.

AIMS

To assess the contamination rate of blood cultures and validate a method to distinguish between true bacteraemia and contamination.

METHODS

We analysed blood culture results from children who were admitted to the paediatric ICU and paediatric wards at the Sardjito Hospital, Yogyakarta, Indonesia between December 2010 and February 2013. For each positive culture result, the type of isolated organism, time to positivity, and the number of positive culture sites were considered to classify the isolate as representing a true bacteraemia or contaminant.

RESULTS

There were 1293 cultures obtained from blood and 308 (23.8%) were positive for bacterial growth. Fifty-three (4.1%) of the total cultures drawn fulfilled criteria for contaminants. The most common blood culture contaminants were coagulase-negative staphylococci.

CONCLUSION

Using standardized criteria, it is possible to implement a working method to identify true nosocomial infection from blood culture contaminant, and thus limit the effect of contaminated blood culture on irrational antibiotic use.

The first 3 minutes: Optimising a short realistic paediatric team resuscitation training session

Inadequate resuscitation leads to death or brain injury. Recent recommendations for resuscitation team training to complement knowledge and skills training highlighted the need for development of an effective team resuscitation training session. This study aimed to evaluate and revise an interprofessional team training session which addressed roles and performance during provision of paediatric resuscitation, through incorporation of real-time, real team simulated training episodes. This study was conducted applying the principles of action research. Two cycles of data collection, evaluation and refinement of a 30-40 minute resuscitation training session for doctors and nurses occurred. Doctors and nurses made up 4 groups of training session participants. Their responses to the training were evaluated through thematic analysis of rich qualitative data gathered in focus groups held immediately after each training session. Major themes included the importance of realism, teamwork, and reflective learning. Findings informed important training session changes. These included; committed in-situ training; team diversity; realistic resources; role flexibility, definition and leadership; increased debriefing time and the addition of a team goal. In conclusion, incorporation of interprofessional resuscitation training which addresses team roles and responsibilities into standard medical and nursing training will enhance preparedness for participation in paediatric resuscitation.

Difficulties with assessment and management of an infant's distress in the postoperative period: Optimising opportunities for interdisciplinary information-sharing

OBJECTIVES

The importance of accurate paediatric patient assessment is well established but under-utilised in managing postoperative medication regimens.

METHODS

Data for this case report were collected through observations of clinical practice, conduct of interviews, and retrieval of information from the medical record. This case report involving a hospitalised 1-year-old boy demonstrates the difficulties associated with assessing and managing postoperative distress, including pain and other clinical conditions related to the surgical procedure.

RESULTS

Postoperatively, there were difficulties in managing pain and an episode of over-sedation, occasioning opiate reversal with naloxone. In addition, he had decreasing oxygen saturation and increased work of breathing. X-ray showed changes consistent with either atelectasis or aspiration, and he was commenced on antibiotics. The patient experienced respiratory distress and required intervention from the medical emergency team.

CONCLUSION

This case demonstrated the importance of comprehensive assessment and careful consideration of alternative causes of an infant's distress using the results of assessment tools to aid decision-making. Communication moderates effective patient care, and more favourable outcomes could be achieved by optimising interdisciplinary information-sharing.

ANTIBIOTIC RESISTANCE AND MORTALITY IN CHILDREN WITH NOSOCOMIAL BLOODSTREAM INFECTION IN A TEACHING HOSPITAL IN INDONESIA

Nosocomial infection is a major problem in hospitals worldwide. Understanding patterns of bacterial etiology and antibiotic susceptibility are important factors to combating nosocomial infection. Among children with nosocomial bloodstream infection (BSI), we identified pathogens and determined antibiotics resistance patterns and mortality rates for antibiotic-susceptible and multidrugresistant (MDR) infection in patients with nosocomial BSI in pediatric wards and PICU at Dr Sardjito Hospital, Indonesia during December 2010 to February 2013. Of 174 isolates from 170 patients, 168 pathogens were bacteria, of which 148 were gram-negative. Pseudomonas aeruginosa, Klebsiella spp, Enterobacteriaceae, Acinetobacter baumanii, and Escherichia coli was found in 55%, 6%, 4%, 1%, and <1%, respectively of the isolates. Imipenem, amikacin, ciprofloxacin, and ceftazadime had the highest sensitivity to nosocomial pathogens at 86%, 84%, 84%, and 75%, respectively. Eleven patients had MDR-infections, 7 of whom died. Among 153 patients infected with bacteria resistant to <3 classes of antibiotics (non-MDR), mortality was 40%, and among 4 patients with fully drug-susceptible sepsis only one died. Thus, substantial mortality was observed in children with nosocomial-BSI, particularly with MDR pathogens. Given the further high risk of resistance with wider use of carbapenems, third generation cephalosporins and flouroquinolones, prevention should be given highest priority in combating hospital-acquired infection.

Creating a journal club competition improves paediatric nurses' participation and engagement

BACKGROUND

To improve journal club participation, innovative approaches are required but few have been described. It was unknown if adding an element of competition, to an established journal club, would increase nurses' participation.

OBJECTIVE

To explore the impact on attendance and participation in a hospital-wide nursing journal club through the introduction of an element of competition.

DESIGN

A descriptive exploratory study.

SETTING AND PARTICIPANTS

An Australian specialist tertiary paediatric hospital with over 1600 nurses.

METHODS

In 2013, 12 hospital wards/departments were randomly assigned a month each to present journal club. Nurses were supported to evaluate an article according to a published framework. A predetermined rubric guided marking. Post competition, all hospital nurses received an anonymous online survey invitation. Demographic, Likert scale and qualitative data were collected. Questions elicited attitudes and perceived barriers or facilitators to participation in the journal club.

RESULTS

Compared to 2012, there was a statistically significant increase in journal club attendance (2013 median=20.5 [IQR=18.2, 27.7] vs. 2012 median=9 [IQR=6.5, 12.5], Mann-Whitney U test, p<0.01). Full online survey responses were received from 289/1674 (response rate 17.3%) of sent invitations (Non-Attendees n=224, Attendees n=65 (including 18 presenters). Overall, Attendees reported journal club had a positive impact on their professional engagement. Presenters rated the journal club format highly as it developed skills and increased their confidence in journal club presentation. Emergent themes were time and location, engagement, topics and content.

CONCLUSION

A competition format can increase nurses' journal club attendance and participation. Further work is required to establish applicability of this format to other settings.

Relationship between Social-Emotional and Neurodevelopment of 2-Year-Old Children with Congenital Heart Disease

OBJECTIVE

The purpose of this study was to describe social-emotional outcomes and the relationship with neurodevelopmental outcomes in a cohort of 2-year-old children who underwent surgery for congenital heart disease (CHD) in infancy, and explore the relationship between the outcomes and parental and surgical factors.

DESIGN

A two-center prospective cross-sectional cohort study.

PATIENTS

A cohort of 105 2-year-olds who underwent surgery in infancy for severe CHD MEASURES: Social-emotional and neurodevelopment was evaluated with the Infant and Toddler Social and Emotional Assessment tool (ITSEA), and the Bayley Scales of Infant Toddler Development, Third Edition.

RESULTS

Neurodevelopment was delayed in the CHD cohort with significantly worse results compared to published Australian-based norms in all domains (P < .001) and in the Cognitive (P < .001) and Language (P < .001) domains with respect to the reported American norms. Social-emotional outcome was similar to Australian norms in all domains but better than the American based norms in the Internalizing domain (P < .05). Higher maternal education was associated to better neurodevelopmental outcome in all domains and better scores in the internalizing and externalizing domains of the ITSEA. There was a moderate correlation (r = 0.43, P < .001) between Language and social-emotional competence. Motor development was influenced by the need for a significant cardiac reoperation.

CONCLUSIONS

The influences of social factors may be underestimated in the outcome of children with CHD. Language development in those with CHD may be improved with intervention targeting social-emotional competence; further research is needed in this area.

Reducing hospital-acquired infections and improving the rational use of antibiotics in a developing country: an effectiveness study

BACKGROUND

Prevention of hospital-acquired infections (HAI) is central to providing safe and high quality healthcare. Transmission of infection between patients by health workers, and the irrational use of antibiotics have been identified as preventable aetiological factors for HAIs. Few studies have addressed this in developing countries.

AIMS

To implement a multifaceted infection control and antibiotic stewardship programme and evaluate its effectiveness on HAIs and antibiotic use.

METHODS

A before-and-after study was conducted over 27 months in a teaching hospital in Indonesia. All children admitted to the paediatric intensive care unit and paediatric wards were observed daily. Assessment of HAIs was made based on the criteria from the Centers for Disease Control and Prevention. The multifaceted intervention consisted of a hand hygiene campaign, antibiotic stewardship (using the WHO Pocket Book of Hospital Care for Children guidelines as standards of antibiotic prescribing for community-acquired infections), and other elementary infection control practices. Data were collected using an identical method in the preintervention and postintervention periods.

RESULTS

We observed a major reduction in HAIs, from 22.6% (277/1227 patients) in the preintervention period to 8.6% (123/1419 patients) in the postintervention period (relative risk (RR) (95% CI) 0.38 (0.31 to 0.46)). Inappropriate antibiotic use declined from 43% (336 of 780 patients who were prescribed antibiotics) to 20.6% (182 of 882 patients) (RR 0.46 (0.40 to 0.55)). Hand hygiene compliance increased from 18.9% (319/1690) to 62.9% (1125/1789) (RR 3.33 (2.99 to 3.70)). In-hospital mortality decreased from 10.4% (127/1227) to 8% (114/1419) (RR 0.78 (0.61 to 0.97)).

CONCLUSIONS

Multifaceted infection control interventions are effective in reducing HAI rates, improving the rational use of antibiotics, increasing hand hygiene compliance, and may reduce mortality in hospitalised children in developing countries.

Interventions to reduce medication errors in pediatric intensive care

OBJECTIVE

To systematically examine the research literature to identify which interventions reduce medication errors in pediatric intensive care units.

DATA SOURCES

Databases were searched from inception to April 2014.

STUDY SELECTION AND DATA EXTRACTION

Studies were included if they involved the conduct of an intervention with the intent of reducing medication errors.

DATA SYNTHESIS

In all, 34 relevant articles were identified. Apart from 1 study, all involved single-arm, before-and-after designs without a comparative, concurrent control group. A total of 6 types of interventions were utilized: computerized physician order entry (CPOE), intravenous systems (ISs), modes of education (MEs), protocols and guidelines (PGs), pharmacist involvement (PI), and support systems for clinical decision making (SSCDs). Statistically significant reductions in medication errors were achieved in 7/8 studies for CPOE, 2/5 studies for ISs, 9/11 studies for MEs, 1/2 studies for PGs, 2/3 studies for PI, and 3/5 studies for SSCDs. The test for subgroup differences showed that there was no statistically significant difference among the 6 subgroups of interventions, χ(2)(5) = 1.88, P = 0.87. The following risk ratio results for meta-analysis were obtained: CPOE: 0.47 (95% CI = 0.28, 0.79); IS: 0.37 (95% CI = 0.19, 0.73); ME: 0.36 (95% CI = 0.22, 0.58); PG: 0.82 (95% CI = 0.21, 3.25); PI: 0.39 (95% CI = 0.10, 1.51), and SSCD: 0.49 (95% CI = 0.23, 1.03).

CONCLUSIONS

Available evidence suggests some aspects of CPOE with decision support, ME, and IS may help in reducing medication errors. Good quality, prospective, observational studies are needed for institutions to determine the most effective interventions.

Comparison of open and closed suction on safety, efficacy and nursing time in a paediatric intensive care unit

BACKGROUND

Endotracheal suctioning (ETS) is one of the most common procedures performed in the paediatric intensive care. The two methods of endotracheal suctioning used are known as open and closed suction, but neither method has been shown to be the superior suction method in the Paediatric Intensive Care Unit (PICU).

PURPOSE

The primary purpose was to compare open and closed suction methods from a physiological, safety and staff resource perspective.

METHODS

All paediatric intensive care patients with an endotracheal tube were included. Between June and September 2011 alternative months were nominated as open or closed suction months. Data were prospectively collected including suction events, staff involved, time taken, use of saline, and change from pre-suction baseline in heart rate (HR), mean arterial pressure (MAP) and oxygen saturation (SpO2). Blocked or dislodged ETTs were recorded as adverse events.

FINDINGS

Closed suction was performed more often per day (7.2 vs 6.0, p<0.01), used significantly less nursing time (23 vs 38 min, p<0.01) and had equivalent rates of adverse events compared to open suction (5 vs 3, p<0.23). Saline lavage usage was significantly higher in the open suction group (18% vs 40%). Open suction demonstrated a greater reduction in SpO2 and nearly three times the incidence of increases in HR and MAP compared to closed suction. Reductions in MAP or HR were comparable across the two methods.

CONCLUSIONS

In conclusion, CS could be performed with less staffing time and number of nurses, less physiological disturbances to our patients and no significant increases in adverse events.

Medication errors in hospitalised children

AIM

This study aims to explore the characteristics of reported medication errors occurring among children in an Australian children's hospital, and to examine the types, causes and contributing factors of medication errors.

METHODS

A retrospective clinical audit was undertaken of medication errors reported to an online incident facility at an Australian children's hospital over a 4-year period.

RESULTS

A total of 2753 medication errors were reported over the 4-year period, with an overall medication error rate of 0.31% per combined admission and presentation, or 6.58 medication errors per 1000 bed days. The two most common severity outcomes were: the medication error occurred before it reached the child (n = 749, 27.2%); and the medication error reached the child who required monitoring to confirm that it resulted in no harm (n = 1519, 55.2%). Common types of medication errors included overdose (n = 579, 21.0%) and dose omission (n = 341, 12.4%). The most common cause relating to communication involved misreading or not reading medication orders (n = 804, 29.2%). Key contributing factors involved communication relating to children's transfer across different clinical settings (n = 929, 33.7%) and the lack of following policies and procedures (n = 617, 22.4%). More than half of the reports (72.5%) were made by nurses.

CONCLUSION

Future research should focus on implementing and evaluating strategies aimed at reducing medication errors relating to analgesics, anti-infectives, cardiovascular agents, fluids and electrolytes and anticlotting agents, as they are consistently represented in the types of medication errors that occur. Greater attention needs to be placed on supporting health professionals in managing these medications.

Prevention of nosocomial infections in developing countries, a systematic review

BACKGROUND

Prevention of nosocomial infection is key to providing good quality, safe healthcare. Infection control programmes (hand-hygiene campaigns and antibiotic stewardship) are effective in reducing nosocomial infections in developed countries. However, the effectiveness of these programmes in developing countries is uncertain.

OBJECTIVE

To evaluate the effectiveness of interventions for preventing nosocomial infections in developing countries.

METHODS

A systematic search for studies which evaluated interventions to prevent nosocomial infection in both adults and children in developing countries was undertaken using PubMed. Only intervention trials with a randomized controlled, quasi-experimental or sequential design were included. Where there was adequate homogeneity, a meta-analysis of specific interventions was performed using the Mantel-Haenzel fixed effects method to estimate the pooled risk difference.

RESULTS

Thirty-four studies were found. Most studies were from South America and Asia. Most were before-and-after intervention studies from tertiary urban hospitals. Hand-hygiene campaigns that were a major component of multifaceted interventions (18 studies) showed the strongest effectiveness for reducing nosocomial infection rates (median effect 49%, effect range 12.7-100%). Hand-hygiene campaigns alone and studies of antibiotic stewardship to improve rational antibiotic use reduced nosocomial infection rates in three studies [risk difference (RD) of -0.09 (95%CI -0.12 to -0.07) and RD of -0.02 (95% CI -0.02 to -0.01), respectively].

CONCLUSIONS

Multifaceted interventions including hand-hygiene campaigns, antibiotic stewardship and other elementary infection control practices are effective in developing countries. The modest effect size of hand-hygiene campaigns alone and negligible effect size of antibiotic stewardship reflect the limited number of studies with sufficient homogeneity to conduct meta-analyses.

Clinical profile of hospitalized children provided with urgent assistance from a medical emergency team

OBJECTIVE

The purpose of this work was to describe the frequency, characteristics, and outcomes of critical events and hospitalized children requiring medical emergency team review.

PATIENTS AND METHODS

We conducted an audit of prospectively collected medical emergency team forms and a retrospective review of medical charts during an 18-month period at a tertiary pediatric hospital in Australia. Critical events were defined as cardiac arrest, endotracheal intubation on the ward, reversal of analgesia or sedation, fluid resuscitation at >/=40 mL/kg, hyponatremia (serum sodium level of </=125 mmol/L), hypernatremia (serum sodium level of >/=155 mmol/L), hypoglycemia (glucose level of </=2 mmol/L), or severe metabolic acidosis (pH </= 7.1).

RESULTS

A total of 172 children had 225 medical emergency team calls (10.6 calls per 1000 hospital admissions and 2.0 calls per 1000 patient-days). Forty-two percent of calls were for infants <1 year old. Preexisting chronic disease was common, with 20% having a chronic underlying neurologic disorder. Forty-four percent of the children were postoperative. The mortality rate of the 172 children was 7.6% in the hospital and 13.4% within 1 year. Thirty-three children had a critical event, with reversal of analgesia being the most common event (n = 11). Postoperative children were more frequently seen in the critical-event group (64% vs 40%). Hospital and 1-year mortality rates were higher for children who had a critical event (16.1% vs 22.6%, respectively) than those who did not (5.7% vs 11.3%).

CONCLUSIONS

Chronic and complex illnesses were prevalent among children provided with urgent medical assistance from the medical emergency team in a tertiary hospital. Children in the postoperative phase were overrepresented among those with a critical event. A critical event significantly increased the risk of hospital mortality. Greater knowledge of high-risk groups is required to further improve outcomes for hospitalized children.

A prospective study of outcome of in-patient paediatric cardiopulmonary arrest

BACKGROUND

Few prospective studies of the incidence and outcome of paediatric in-hospital cardiopulmonary arrest have been reported to enable quality assurance comparisons within and between institutions.

METHODS

All cardiac and respiratory arrests and their management over a 41-month period in children not subject to palliative treatment or to a 'do not resuscitate' order were recorded and analysed using the Utstein template.

RESULTS

Cardiac arrest occurred in a total of 111 of 104,780 admissions (1.06/1000) while respiratory arrest alone occurred in 36 (0.34/1000). Return of spontaneous circulation (ROSC) was achieved in 81 patients (73%) in cardiac arrest but only 40 (36%) were discharged from hospital and 38 (34%) survived for 1 year. The 1-year survival from respiratory arrest alone was 97%. Cardiac arrest was four times more common (89 versus 22) and approximately 90 times the incidence in the intensive care unit compared with wards but 1-year survival was similar (34% versus 36%). The initial heart rhythms were hypotensive-bradycardia in 73 (66%) with 38% survival; asystole in 17 (15%) with 12% survival; ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT) in 10 (9%) with 40% survival; pulseless electrical activity (PEA) in 10 (9%) with 30% survival and SVT in 1 with survival. Secondary ventricular fibrillation occurred in 15 children given adrenaline (epinephrine) for treatment of asystole, hypotensive-bradycardia or PEA of whom 11 had received adrenaline in an initial dose of > 15 mcg/kg and 4 had < 15 mcg/kg (P = 0.0013). Eleven of 15 patients (73%) in secondary VF never achieved ROSC.

CONCLUSIONS

In-patient paediatric cardiac arrest has a mediocre outcome with a better outlook if the initial rhythm is hypotensive-bradycardia, VF or pulsatile VT. Doses of adrenaline greater than 15 mcg/kg given for non-shockable rhythms may cause secondary VF which has a worse outcome than primary VF.

Reduction of paediatric in-patient cardiac arrest and death with a medical emergency team: preliminary results

AIMS

To determine the impact of a paediatric medical emergency team (MET) on cardiac arrest, mortality, and unplanned admission to intensive care in a paediatric tertiary care hospital.

METHODS

Comparison of the retrospective incidence of cardiac arrest and death during 41 months before introduction of a MET service with the prospective incidence of these events during 12 months after its introduction. Comparison of transgression of MET call criteria in patients who arrested and died before and after introduction of MET.

RESULTS

Cardiac arrest decreased from 20 among 104 780 admissions (0.19/1000) to 4 among 35 892 admissions (0.11/1000) (risk ratio 1.71, 95% CI 0.59 to 5.01), while death decreased from 13 (0.12/1000) to 2 (0.06/1000) during these periods (risk ratio 2.22, 95% CI 0.50 to 9.87). Unplanned admissions to intensive care increased from 20 (SD 6) to 24 (SD 9) per month. The incidence of transgression of MET call criteria in patients who arrested decreased from 17 to 0 (risk difference 0.16/1000, 95% CI 0.09 to 0.24), and in those who died, decreased from 12 to 0 (risk difference 0.11/1000, 95% CI 0.05 to 0.18) after introduction of MET.

CONCLUSIONS

Introduction of a medical emergency team service was coincident with a reduction of cardiac arrest and mortality and a slight increase in admissions to intensive care.

Effect of reusing suction catheters on the occurrence of pneumonia in children

OBJECTIVE

The purpose of this study was to determine whether disposable suction catheters can be reused in the same patient for a 24-hour period without affecting the incidence of pneumonia.

DESIGN

The study design was a randomized controlled trial.

SETTING

The study was conducted in the pediatric intensive care unit of a tertiary pediatric center.

SAMPLE

Subjects included 486 children with an endotracheal tube in place.

OUTCOME MEASURES

The development of pneumonia, diagnosed with radiographic and clinical evidence, was the measure. Cost analysis was also undertaken.

METHOD

Subjects in the study group (n = 241) were suctioned using the same catheter for a 24-hour period. Those in the control group (n = 245) had a new catheter for each episode of suctioning.

RESULTS

Pneumonia developed in 14 members (5.71%) of the control group and in 12 members (4.98%) of the study group, a difference of 0.7% (95% CI, -3.3% to 4.7%). Cost analysis indicated a saving of Aust $4.14 per patient per day.

CONCLUSION

Reusing suction catheters for up to 24 hours is both safe and cost-effective.

Effect of testing for IgG avidity in the diagnosis of Toxoplasma gondii infection in pregnant women: experience in a US reference laboratory

The usefulness of testing for IgG avidity in association with Toxoplasma gondii was evaluated in a US reference laboratory. European investigators have reported that high-avidity IgG toxoplasma antibodies exclude acute infection in the preceding 3 months. In this US study, 125 serum samples taken from 125 pregnant women in the first trimester were chosen retrospectively, because either the IgM or differential agglutination (AC/HS) test in the Toxoplasma serologic profile suggested or was equivocal for a recently acquired infection. Of 93 (74.4%) serum samples with either positive or equivocal results in the IgM ELISA, 52 (55.9%) had high-avidity antibodies, which suggests that the infection probably was acquired before gestation. Of 87 (69.6%) serum samples with an acute or equivocal result in the AC/HS test, 35 (40.2%) had high-avidity antibodies. Forty women were given spiramycin, to prevent congenital transmission, and 7 (17.5%) had high-avidity antibodies. These findings highlight the value of testing a single serum sample obtained in the first trimester of pregnancy for IgG avidity.

The factor V Leiden mutation is not a common cause of recurrent miscarriage

Some investigators suggest that placental thrombosis and infarction can cause recurrent miscarriage. We have shown that the common missense mutation in the factor V gene, the Leiden mutation, which renders factor Va resistant to cleavage inactivation by activated protein C, predisposes to placental thrombosis and spontaneous miscarriage. Our objective was to determine the frequency of the Leiden mutation in a population with well-characterized idiopathic recurrent miscarriage. DNA was extracted from whole blood of 40 couples with a history of idiopathic recurrent miscarriage and 25 couples with a history of proven fertility (seven or more live births). The polymerase chain reaction was used to amplify exon 10 of the factor V gene followed by allele-specific restriction with Mnl1 for mutation detection. Results were analyzed with a chi 2 contingency table. None of the 40 women with idiopathic recurrent miscarriage carried the mutation and only one of their reproductive partners was heterozygous for the mutation. Similarly, none of the control women carried the mutation, and only one of the 25 control male partners was heterozygous for the mutation. In our referral population, the factor V Leiden mutation which predisposes to thrombosis is not a common cause of recurrent miscarriage.

Guidelines for the retention, storage, and use of residual dried blood spot samples after newborn screening analysis: statement of the Council of Regional Networks for Genetic Services

These guidelines provide scientific information for policy development by state health departments considering appropriate use of newborn screening specimens after screening tests are finished. Information was collected, debated, and formulated into a policy statement by the Newborn Screening Committee of the Council of Regional Networks for Genetic Services (CORN), a federally funded national consortium of representatives from 10 regional genetics networks. Newborn screening programs vary widely in approaches and policies concerning residual dried blood spot samples (DBS) collected for newborn screening. Recognition of the epidemiological utility of DBS samples for HIV seroprevalence surveys and a growing interest in DBSs for DNA analysis has intensified consideration of issues regarding retention, storage, and use of residual DBS samples. Potentially these samples provide a genetic material "bank" for all newborns nationwide. Their values as a resource for other uses has already been recognized by scientists, administrators, and judicial officials. Programs should promulgate rules for retention and use of residual newborn screening DBS samples based on scientifically valid information. Banking of newborn samples as sources of genetic material should be considered in light of potential benefit or harm to society.

Preliminary observations of a bacteriophage infecting Xenorhabdus luminescens (Enterobacteriaceae)

A bacteriophage infective to Xenorhabdus luminescens, a bacterial symbiont of heterorhabditid nematodes, was recovered from insects that supported poor nematode development. Plaque tests showed the phage particles to be infective only to primary and not secondary colonies of X. luminescens. The phage was not infective to X. nematophilus primaries or secondaries. The bacteriophage particles ranged 80-90 nm in length, with the head ranging from 40 to 50 nm in diameter. Restriction analysis was performed on isolated bacteriophage DNA. This first report of a bacteriophage from Xenorhabdus species has practical implications since it could be detrimental to cultures of Heterorhabditis nematodes that are being produced throughout the world for the biological control of insects.
