Improving food insecurity screening across a health system throughout the COVID-19 pandemic

BACKGROUND

Food insecurity has direct and indirect negative outcomes on the physical and mental health of children, with impacts throughout adult life. Rates of food insecurity have increased dramatically since the start of the COVID-19 pandemic. The American Academy of Pediatrics recommends paediatricians screen and intervene to address food insecurity. We aimed to increase the percentage of patient encounters with food insecurity screening completion at the paediatric medical home from 0% to 85% by July 2020 with extension to the paediatric emergency department (ED) and paediatric specialty clinic in the following year.

METHODS

This multicentre project occurred in three sites within our health system: a teaching safety-net, paediatric medical home; a paediatric ED; and five divisions within paediatric specialty medical clinics. A screening tool was created using the validated Hunger Vital Sign Questionnaire. A standard screening, documentation and referral process was developed. The Model for Improvement was used testing changes via Plan-Do-Study-Act cycles.

RESULTS

The percentage of households screened for food insecurity increased from a median of 0% to 30% for all sites combined. There was significant variability in screening with the ED screening a median of 24% and the medical home screening 80% by the end of the study period. A total of 9842 households (20.9%) screened were food insecure. During the study period, 895 families with 3925 household members received 69 791 pounds of food from our primary community resource using our clinic's food prescription. Of these families, 44% (398) also qualified for the US Department of Agriculture programme ensuring ongoing food distribution up to twice a month.

DISCUSSION

Using quality improvement methodology to address a critical community need, we implemented food insecurity screening across a hospital system including multiple sites and specialties and provided critical resources to households in need.

Nucleic Acid Testing for Diagnosis of Perinatally Acquired Hepatitis C Virus Infection in Early Infancy

BACKGROUND

Most US children with perinatal hepatitis C virus (HCV) exposure fail to receive the recommended anti-HCV antibody test at age ≥18 months. Earlier testing for viral RNA might facilitate increased screening, but sensitivity of this approach has not been established. We hypothesized that modern HCV-RNA RT-PCR platforms would adequately detect infected infants.

METHODS

Nationwide Children's Hospital electronic health records from 1/1/2008 to 30/6/2018 were reviewed to identify perinatally exposed infants tested by HCV-RNA RT-PCR at age 2-6 months. Diagnostic performance was determined using a composite case definition: (1) infected children had positive repeat HCV-RNA testing or positive anti-HCV at age ≥24 months; (2) uninfected children lacked these criteria and had negative anti-HCV at age ≥18 months.

RESULTS

770 perinatally exposed infants underwent HCV-RNA testing at age 2-6 months. Of these, 28 (3.6%) tested positive; viremia was confirmed in all who underwent repeat testing (n = 27). Among 742 infants with negative HCV-RNA results, 226 received follow-up anti-HCV testing at age ≥18 months, of whom 223 tested negative. Three children had low-positive anti-HCV results at age 18-24 months that were negative upon retesting after age 24 months, possibly indicating waning maternal antibodies. Using the composite case definitions, early HCV-RNA screening demonstrated sensitivity of 100% (87.5-100%, Wilson-Brown 95% CI) and specificity of 100% (98.3-100%).

CONCLUSIONS

Modern HCV-RNA RT-PCR assays have excellent sensitivity for early diagnosis of perinatally acquired infection and could aid HCV surveillance given the substantial loss to follow-up at ≥18 months of age.

Molecular and Clinical Comparison of Enterovirus D68 Outbreaks among Hospitalized Children, Ohio, USA, 2014 and 2018

Enterovirus D68 (EV-D68) causes respiratory tract infections and neurologic manifestations. We compared the clinical manifestations from 2 EV-D68 outbreaks in 2014 and 2018 and a low-activity period in 2016 among hospitalized children in central Ohio, USA, and used PCR and sequencing to enable phylogenetic comparisons. During both outbreak periods, infected children had respiratory manifestations that led to an increase in hospital admissions for asthma. The 2018 EV-D68 outbreak appeared to be milder in terms of respiratory illness, as shown by lower rates of pediatric intensive care unit admission. However, the frequency of severe neurologic manifestations was higher in 2018 than in 2014. During the same period in 2016, we noted neither an increase in EV-D68 nor a significant increase in asthma-related admissions. Phylogenetic analyses showed that EV-D68 isolates from 2018 clustered differently within clade B than did isolates from 2014 and are perhaps associated with a different EV-D68 subclade.

Enterovirus D68 in Hospitalized Children: Sequence Variation, Viral Loads and Clinical Outcomes

Background

An outbreak of enterovirus D68 (EV-D68) caused severe respiratory illness in 2014. The disease spectrum of EV-D68 infections in children with underlying medical conditions other than asthma, the role of EV-D68 loads on clinical illness, and the variation of EV-D68 strains within the same institution over time have not been described. We sought to define the association between EV-D68 loads and sequence variation, and the clinical characteristic in hospitalized children at our institution from 2011 to 2014.

Methods

May through November 2014, and August to September 2011 to 2013, a convenience sample of nasopharyngeal specimens from children with rhinovirus (RV)/EV respiratory infections were tested for EV-D68 by RT-PCR. Clinical data were compared between children with RV/EV-non-EV-D68 and EV-D68 infections, and among children with EV-D68 infections categorized as healthy, asthmatics, and chronic medical conditions. EV-D68 loads were analyzed in relation to disease severity parameters and sequence variability characterized over time.

Results

In 2014, 44% (192/438) of samples tested positive for EV-D68 vs. 10% (13/130) in 2011–13 (p<0.0001). PICU admissions (p<0.0001) and non-invasive ventilation (p<0.0001) were more common in children with EV-D68 vs. RV/EV-non-EV-D68 infections. Asthmatic EV-D68+ children, required supplemental oxygen administration (p = 0.03) and PICU admissions (p <0.001) more frequently than healthy children or those with chronic medical conditions; however oxygen duration (p<0.0001), and both PICU and total hospital stay (p<0.01) were greater in children with underlying medical conditions, irrespective of viral burden. By phylogenetic analysis, the 2014 EV-D68 strains clustered into a new sublineage within clade B.

Conclusions

This is one of the largest pediatric cohorts described from the EV-D68 outbreak. Irrespective of viral loads, EV-D68 was associated with high morbidity in children with asthma and co-morbidities. While EV-D68 circulated before 2014, the outbreak isolates clustered differently than those from prior years.

Ebola virus disease: epidemiology, clinical presentation, and diagnostic and therapeutic modalities

Ebola virus disease (EVD) is a severe multisystem disease. Prehospital personnel, hospitals, and clinicians must be prepared to provide care for patients with EVD, with special attention to rigorous infection control in order to limit the spread of infection. Children with EVD are an especially challenging population, as the initial symptoms are nonspecific and difficult to differentiate from several common infections. For children presenting with a syndrome consistent with EVD, it is extremely important that healthcare workers identify epidemiologic risk factors, such as recent travel to an affected country or exposure to a patient with suspected or known EVD. Given the high morbidity and mortality of this disease, clinical efforts should focus on early diagnosis, appropriate infection control, and supportive care.

Syndecan contributes to heart cell specification and lumen formation during Drosophila cardiogenesis

The transmembrane proteoglycan Syndecan contributes to cell surface signaling of diverse ligands in mammals, yet in Drosophila, genetic evidence links Syndecan only to the Slit receptor Roundabout and to the receptor tyrosine phosphatase LAR. Here we characterize the requirement for syndecan in the determination and morphogenesis of the Drosophila heart, and reveal two phases of activity, indicating that Syndecan is a co-factor in at least two signaling events in this tissue. There is a stochastic failure to determine heart cell progenitors in a subset of abdominal hemisegments in embryos mutant for syndecan, and subsequent to Syndecan depletion by RNA interference. This phenotype is sensitive to gene dosage in the FGF receptor (Heartless), its ligand, Pyramus, as well as BMP-ligand Decapentaplegic (Dpp) and co-factor Sara. Syndecan is also required for lumen formation during assembly of the heart vessel, a phenotype shared with mutations in the Slit and Integrin signaling pathways. Phenotypic interactions of syndecan with slit and Integrin mutants suggest intersecting function, consistent with Syndecan acting as a co-receptor for Slit in the Drosophila heart.

Preliminary in vivo studies on the osteogenic potential of bone morphogenetic proteins delivered from an absorbable puttylike polymer matrix

This article describes preliminary in vivo studies evaluating the osteogeneic potential of bone morphogenetic proteins (BMPs) delivered from an absorbable puttylike polymer matrix. In the first study, bovine-derived bone morphogenetic proteins were incorporated in an polymer matrix consisting of 50:50 poly(DL-lactide-co-glycolide) dissolved in N-methyl-2-pyrrolidone. The matrix was implanted in an 8 mm critical-size calvarial defect created in the skull of adult Sprague-Dawley rats (n = 5 per treatment group). After 28 days, the implant sites were removed and examined for new bone formation, polymer degradation, and tissue reaction. Gamma-irradiated polymer matrices appeared to give more bone formation than nonirradiated samples (histological analysis; 2. 76 + 1.34 mm(2) of bone versus 1.30 + 0.90 mm(2) of bone, respectively and x-ray analysis; 27.2 + 15.9 mm(2) of bone versus 20. 7 + 16.7 mm(2) of bone, respectively) and less residual polymer (0.0 + 0.0 versus 0.2 + 0.4, respectively). The polymer implants with bone morphogenetic protein also gave less inflammatory response than the polymer controls (gamma irradiated polymer/BMP = 1.8 + 0.4 and nonirradiated polymer/BMP = 1.2 + 0.4 versus polymer only = 3.0 + 1. 2, respectively). However, despite trends in both the x-ray and histological data there was no statistical difference in the amount of new bone formed among the four treatment groups (P > 0.05). This was most likely due to the large variance in the data scatter and the small number of animals per group. In the second animal study, bovine-derived BMPs and the polymeric carrier were gamma irradiated separately, at doses of 1.5 or 2.5 Mrad, and their ability to form bone in a rat skull onlay model was evaluated using Sprague-Dawley rats (n = 5 per treatment group). Histomorphometry of skull caps harvested 28 days after implantation showed no significant differences as compared to non-irradiated samples, in implant area, new bone area, and percent new bone (P > 0.05). These results suggest gamma irradiation may be useful in sterilization of the bovine-derived BMPs and the polymeric carrier for potential bone repair and/or regeneration applications.

Selection of medical technology students in a hospital-based program

This article describes a process for selection of medical technology students into a hospital-based program. The process uses a weighting method for selection criteria and numerical ranking of applicants by a point system. Tools developed by the selection committee are discussed: Pre-Interview Rating Form, Interview Rating Form, Interview Rating Form Score Sheet, and Interview Questions Sets. The structured selection interview is described in detail. The process might easily be adapted to other hospital-based allied health programs.

The Inglis Street Activities Centre: a transitional program for psychiatric clients

The Inglis Street Activity Centre was initiated in November 1975 to meet the growing need in Halifax for a structured aftercare program for the long-term psychiatric patients being discharged from the Abbie J. Lane Memorial Hospital. It is a pilot program, operated by the Abbie J. Lane staff five afternoons per week, in a large house in a residential area of the city. Inpatients who are being prepared for discharge begin attending the program while in hospital, and continue after discharge until they are able to fully integrate into the community. Clients are accepted from other agencies as well, and the program is seen as being preventive as well as a provider of aftercare.

Of the 64 clients seen in the first year of operation, only seven were readmitted to hospital, and the length of hospital stay for these seven was significantly reduced. The operating expenses were minimal ($11,456 including salaries) and it is felt that this has been an effective model for assisting the long-term psychiatric client to successfully make the transition from hospital to community.
