Multifaceted quality improvement initiative to decrease pediatric asthma readmissions.

BACKGROUND: Asthma is the most common chronic disease of childhood and a leading cause of hospitalization in children. A primary goal of asthma control is prevention of hospitalizations. A hospital admission is the single strongest predictor of future hospital admissions for asthma. The 30-day asthma readmission rate at our institution was significantly higher than that of other hospitals in the Children's Hospital Association. As a result, a multifaceted quality improvement project was undertaken with the goal of reducing the 30-day inpatient asthma readmission rate by 50% within two years. METHODS: Analysis of our institution's readmission patterns, value stream mapping of asthma admission, discharge, and follow-up processes, literature review, and examination of comparable successful programs around the United States were all utilized to identify potential targets for intervention. Interventions were implemented in a stepwise manner, and included increasing inhaler availability after discharge, modifying asthma education strategies, and providing in-home post-discharge follow-up. The primary outcome was a running 12-month average 30-day inpatient readmission rate. Secondary outcomes included process measures for individual interventions. RESULTS: From a peak of 7.98% in January 2013, a steady decline to 1.65% was observed by July 2014, which represented a 79.3% reduction in 30-day readmissions. CONCLUSION: A significant decrease in hospital readmissions for pediatric asthma is possible, through comprehensive, multidisciplinary quality improvement that spans the continuum of care.

Assessment and management of anxiety and depression in a pediatric high-risk asthma clinic.

OBJECTIVE: The aims of this study were to determine the prevalence of positive mental health (MH) screens in a pediatric high-risk asthma (HRA) clinic population, and to determine the success rate of engagement in MH services before and after adding a clinical psychologist to our multidisciplinary clinic. HYPOTHESIS: We hypothesized that the HRA population would have a higher prevalence of anxiety/depression symptoms than that previously reported for the general pediatric asthma population. We anticipated that the presence of an embedded psychologist in HRA clinic would facilitate successful connection to MH services. METHODS: Pediatric patients in the HRA clinic were prospectively screened for anxiety and depression using validated screening instruments. Positive scores were referred for MH services. Time to MH service engagement was recorded before and after the addition of a clinical psychologist. RESULTS: A total of 186 patients were screened; 60% had a positive MH screen. Female sex was associated with higher median scores on both screening tools and higher likelihood of engagement in MH services. After addition of a clinical psychologist, new engagement in MH services increased (20% vs. 80%, p < 0.0001), and median time to engagement decreased (14.5 vs. 0.0 months, p = 0.003). CONCLUSION: There is a high prevalence of anxiety and depression in this pediatric HRA population. Success of engagement in MH services improved after a clinical psychologist joined our multidisciplinary team, suggesting access to care as a primary barrier to engagement.

Efficacy, cost effectiveness, and sustainability of a pediatric high risk asthma clinic.

AIM: At our institution, a pediatric High Risk Asthma clinic has been in operation for over 15 years, targeting children with poorly controlled, and difficult to treat asthma. This study evaluates the outcomes and cost-effectiveness of the High Risk Asthma clinic from 2000 through 2014. METHODS: A retrospective chart review was performed on all patients entering High Risk Asthma clinic from 2000-2014, and total hospitalizations and Emergency Department visits were tallied for the year prior to entering clinic and the year after. Costs incurred, and reimbursements obtained from payors were tallied to determine cost-effectiveness and sustainability. RESULTS: Consistent decreases in hospitalizations (51.2% decrease, P < 0.001) and Emergency Department visits (23.0% decrease, P = 0.048) were seen for patients entering High Risk Asthma clinic, with commensurate significant decreases in related costs. Reimbursements received for outpatient services were sufficient to offset operational costs of the High Risk Asthma clinic, when both clinic visit, and pulmonary function testing charges were included. CONCLUSIONS: A pediatric High Risk Asthma clinic model is efficacious in decreasing hospitalizations and Emergency Department visits for a difficult to treat population, and such a model can be cost-effective and sustainable.

Elastic properties of the respiratory system in infants with cystic fibrosis.

Respiratory system compliance (Crs) in infants with cystic fibrosis (CF) has been reported as decreased or not different compared with healthy control subjects; however, the reported measurements of Crs were "quasi-static" or by the single-breath occlusion technique, with all measurements limited to tidal lung volume, as well as using inspiratory rather than expiratory pressures. We compared the passive elastic properties of the respiratory system of sleeping infants with CF (n = 10) and healthy control subjects (n = 34) by measuring static deflation pressure--volume (PV) curves from a lung volume at 30 cm H(2)O (V(30)) to FRC. There was no significant difference between the groups for Crs, which was measured as the slope between airway relaxation pressures of 5 and 15 cm H(2)O, the linear portion of the deflation PV curve. In addition, when PV curves were normalized to V(30), there were no differences between the infants with CF and healthy control subjects in the fractional volumes at any airway pressure. The infants with CF had significantly lower forced expiratory flows; however, lower flows did not correlate with fractional volumes measured from the PV curve. Our findings indicate that infants with CF have normal elastic properties of the respiratory system.

Spirometry in 3- to 6-year-old children with cystic fibrosis.

Spirometry is routinely used to assess pulmonary function of older children and adults with cystic fibrosis (CF); however, few data exist concerning the preschool age group. We have reported normative spirometric data for 3- to 6-year-old children. The current study was designed to assess a similarly aged group of clinically stable patients with CF. Thirty-three of 38 children with CF were able to perform 2 or 3 technically acceptable maneuvers. These patients had significantly decreased FVC, FEV(1), FEV(1)/FVC, and FEF(25-75) when expressed as z scores (number of SD from predicted): -0.75 +/- 1.63, -1.23 +/- 1.97, -0.87 +/- 1.33, and -0.74 +/- 1.63, respectively. There were significant positive correlations of the Brasfield radiological score with FVC and FEV(1) z scores (r(2) = 0.26, p < 0.01 and r(2) = 0.24, p < 0.01). In addition, homozygous patients for the DeltaF508 mutation had lower z scores for FVC (-1.21 versus 0.47, p < 0.01) and FEV(1) (-1.38 versus 0.21, p < 0.05) than heterozygous patients. Of the 14 patients who had full flow-volume spirometric measurements during infancy, 10 had FEF(25-75) z scores greater than -2 at both evaluations. Our findings suggest that spirometry can successfully be used to assess lung function in preschool children with CF and has the potential for longitudinal assessment from infancy through adulthood.
