Improving Discharge Safety in a Pediatric Emergency Department.

BACKGROUND AND OBJECTIVES: Discharge from the emergency department (ED) involves a complex series of steps to ensure a safe transition to home and follow-up care. Preventable, discharge-related serious safety events (SSEs) in our ED highlighted local vulnerabilities. We aimed to improve ED discharge by implementing a standardized discharge process with emphasis on multidisciplinary communication and family engagement. METHODS: At a tertiary children's hospital, we used the model for improvement to revise discharge care. Interventions included a new discharge checklist, a provider huddle emphasizing discharge vital signs, and a scripted discharge review of instructions with families. We used statistical process control to evaluate performance. Primary outcomes included elimination of preventable, discharge-related SSEs and Press Ganey survey results assessing caregiver information for care of child at home. A secondary outcome was number of days between preventable low-level (near-miss, no or minimal harm) events. Process measures included discharge checklist adoption and vital sign acquisition. Balancing measures were length of stay (LOS) and return rates. RESULTS: Over the study period, there were no preventable SSEs and low-level event frequency improved to a peak of >150 days between events. Press Ganey responses regarding quality of discharge information did not change (62%). Checklist use was rapidly adopted, reaching 94%. Vital sign acquisition increased from 67% to 83%. There was no change in the balancing measures of median LOS or return visit rates. CONCLUSIONS: The development and implementation of a standardized discharge process led to the elimination of reported discharge-related events, without increasing LOS or return visits.

An observational study of febrile seizures: the importance of viral infection and immunization.

BACKGROUND: Febrile seizures are common in young children. Annual peaks in incidence mirror increased respiratory virus activity during winter. Limited virological data are available using modern diagnostic techniques for children with febrile seizures. We aimed to determine the frequency of detection of specific viral pathogens in children with febrile seizures, to describe risk factors including recent vaccination and clinical features associated with specific etiologies. METHODS: An observational study was performed. Children aged 6 months to 5 years presenting to the Emergency Department of a tertiary children's hospital in Western Australia with febrile seizures were enrolled between March 2012 and October 2013. Demographic, clinical data and vaccination history were collected, and virological testing was performed on per-nasal and per-rectal samples. RESULTS: One hundred fifty one patients (72 female; median age 1.7y; range 6 m-4y9m) were enrolled. Virological testing was completed for 143/151 (95%). At least one virus was detected in 102/143 patients (71%). The most commonly identified were rhinoviruses (31/143, 22%), adenovirus (30/151, 21%), enteroviruses, (28/143, 20%), influenza (19/143, 13%) and HHV6 (17/143, 12%). More than one virus was found in 48/143 (34%). No significant clinical differences were observed when children with a pathogen identified were compared with those with no pathogen detected. Febrile seizures occurred within 14 days of vaccine administration in 16/151 (11%). CONCLUSION: At least one virus was detected in over two thirds of cases tested (commonly picornaviruses, adenovirus and influenza). Viral co-infections were frequently identified. Febrile seizures occurred infrequently following immunization.

Recurrent rhinovirus detections in children following a rhinovirus-induced wheezing exacerbation: A retrospective study.

INTRODUCTION: It is unclear if children with a rhinovirus (RV)-induced wheezing exacerbation are more susceptible to viruses longitudinally, and whether a parental history of asthma and/or allergy impacts their susceptibility. The objective of this study was to determine if RV, RV-A and RV-C related wheezing exacerbations in children were associated with prior or subsequent viral detections and investigate the role of parental history of asthma and allergy. MATERIALS AND METHODS: Children presenting to hospital with acute wheeze were prospectively recruited and tested for respiratory viruses. Data on viruses detected in other respiratory samples (May 1997 to December 2012) were collected from hospital microbiology records and additional RV testing was performed on stored hospital respiratory samples (September 2009 to December 2012). A positive parental history was defined as either parent with self-reported asthma and/or allergy. RESULTS: At recruitment, RV was detected in 69.2% of samples from children with an acute wheezing episode (n=373, 0-16 years of age), with RV-C the most common virus (65.5%). Children with a history of parental asthma and/or allergy and RV at recruitment had a 14-fold increased incidence rate ratio (IRR) of subsequent RV detection (IRR 14.0, 95% CI 1.9-104.1; p=0.01) compared with children without RV at recruitment. Children without this parental history had a reduced incident rate ratio for samples assessed during this time (IRR 0.5, 95% CI 0.3-0.9; p=0.03). CONCLUSION: Children with a parental history of asthma and/or allergy may become more susceptible to recurrent symptomatic RV infections.

Influenza antiviral resistance in the Asia-Pacific region during 2011.

Despite greater than 99% of influenza A viruses circulating in the Asia-Pacific region being resistant to the adamantane antiviral drugs in 2011, the large majority of influenza A (>97%) and B strains (∼99%) remained susceptible to the neuraminidase inhibitors oseltamivir and zanamivir. However, compared to the first year of the 2009 pandemic, cases of oseltamivir-resistant A(H1N1)pdm09 viruses with the H275Y neuraminidase mutation increased in 2011, primarily due to an outbreak of oseltamivir-resistant viruses that occurred in Newcastle, as reported in Hurt et al. (2011c, 2012a), where the majority of the resistant viruses were from community patients not being treated with oseltamivir. A small number of influenza B viruses with reduced oseltamivir or zanamivir susceptibility were also detected. The increased detection of neuraminidase inhibitor resistant strains circulating in the community and the detection of novel variants with reduced susceptibility are reminders that monitoring of influenza viruses is important to ensure that antiviral treatment guidelines remain appropriate.

Seasonality of respiratory viral identification varies with age and Aboriginality in metropolitan Western Australia.

BACKGROUND: Viral respiratory infections are a major cause of pediatric illness. It is not known whether seasonality of viruses differs between Aboriginal and non-Aboriginal children of varying ages. METHODS: We extracted data on respiratory syncytial virus (RSV), influenza viruses A and B, parainfluenza virus types 1, 2, and 3 and adenovirus identified through cell culture or direct immunofluorescence between 1997 and 2005 from nasopharyngeal or throat specimens at Western Australia's only pediatric hospital. We used harmonic analysis in generalized linear models to examine the variations in seasonality of these viruses with Aboriginality and age. RESULTS: A respiratory virus was identified in 32% of 32 741 specimens. RSV (18.6%), influenza virus A (5.1%), and parainfluenza virus 3 (4.0%) were most common. The median age at time of identification was lower in Aboriginal children than non-Aboriginal for all viruses except RSV. Seasonality differed between all viruses and varied with age for RSV, influenza viruses and adenovirus. Influenza viruses A and B activity peaked earlier in Aboriginal than non-Aboriginal children during 1997, 1998, and 2002. CONCLUSIONS: All viruses showed distinct seasonality. Variability with age and different seasonal patterns for influenza viruses in Aboriginal children compared with non-Aboriginal children has to be taken into account when identifying target groups and timing for vaccination and other interventions.
