Asthma outcomes in pediatric patients with 30-day follow-up after an asthma hospitalization in a Medicaid-managed care program.

BACKGROUND: National asthma guidelines recommend an outpatient follow-up after hospitalization for asthma. Our aim is determine if a follow-up visit within 30 days after an asthma hospitalization impacts risk for re-hospitalization and emergency department visits for asthma within the following year. METHODS: This was a retrospective cohort study of claims data of Texas Children's Health Plan (a Medicaid managed care program) members age 1 to <18 years and hospitalized for asthma between January 1, 2012, and December 31, 2018. Primary outcomes were days to re-hospitalization and emergency department visit between 30 days and 365 days following the index hospitalization. RESULTS: We identified 1,485 children age 1 to <18 years hospitalized for asthma. Comparing those with a 30 day follow-up to those without, there was no difference in days to re-hospitalization (adjusted hazard ratio 1.23, 95% Confidence Interval (CI) 0.74-2.06) or emergency department visit for asthma (aHR 1.08, 95% CI 0.88-1.33). Inhaled corticosteroid and short acting beta agonist dispensing were greater in the group completing the 30 day follow-up (means of 2.8 and 4.8 respectively for those with follow-up, 1.6 and 3.5 respectively for those without, p < 0.0001). CONCLUSION: Having a follow-up outpatient visit within 30 days of an asthma hospitalization is not associated with a decrease in asthma re-hospitalization or emergency department visit in the 30-365 day period following the index hospitalization. Non-adherence to regular use of inhaled corticosteroid medication was high in both groups. These findings suggest need for improvement in the quality and quantity of post hospital asthma follow-up.

Multi-center retrospective study of children with sickle cell disease admitted to pediatric intensive care units in the United States.

Data on outcomes and interventions for children with sickle cell disease (SCD) admitted to a pediatric intensive care units (PICU) are unknown. We provide the first comprehensive multi-center report on PICU interventions associated with death, the need for invasive respiratory support or stroke among critically ill children with SCD. We collected retrospective multi-center cohort data from January 1, 2012 to December 31, 2019 utilizing the Virtual Pediatric Systems, LLC database. We identified 3388 unique children with SCD, accounting for a total of 5264 PICU admissions from 138 PICUs. The overall mortality rate for the PICU admissions cohort was 1.8% (95/5264 PICU admissions, 95/3388 [2.8%] of all unique patients), the rate of needing of needing Invasive Respiratory Support (IRS, a composite category of exposure) was 21.3% (872/4093 PICU admissions with complete data) and the overall rate of stroke (ischemic or hemorrhagic) was 12.5% (657/5264 PICU admissions). In multivariable analysis adjusting for admission age category, sex, race/ethnicity, PRISM-3 score at admission, exposure to IRS, quartile of unit volume of patients with SCD, and patient origin, admitted children who needed invasive respiratory support (IRS) had higher adjusted odds ratios for mortality (adjusted odds ratio [aOR], 19.72; 95% confidence interval [CI] 8.98-43.29; p < 0.001), although admitted children > 2 years old had decreased aOR for needing IRS (aOR 0.25-0.62; 95% CI 0.16-0.94; p < 0.001-0.025). By contrast, admitted children > 2 years old had a strikingly increased aOR for stroke (aOR 7.57-16.32; 95% CI 2.25-52.15; p < 0.001). These groups may represent PICU-specific subsets of patients with SCD who are at higher risk for more serious illness and should deserve early consideration for referral to a pediatric institution providing comprehensive care for patients with SCD.

Pulmonary specialist involvement in critical asthma in the pediatric intensive care unit: A retrospective review.

INTRODUCTION: Asthma is one of the most common chronic diseases of childhood. There is a scarcity of published literature on critical asthma, considered acute asthma requiring pediatric intensive care unit (PICU) admission. The goal of this study was to describe the clinical care of children with critical asthma admitted to a single center PICU and to determine whether pulmonary medicine consultation during admission impacted outcomes. METHODS: Retrospective chart review of known asthma patients aged 4-18 years admitted to a quaternary PICU between 01/2013 and 07/2019 for management of critical asthma. RESULTS: A total of 179 patients were enrolled with median age of 8 years. Median hospital length of stay (LOS) was 3.2 days and PICU LOS was 1.5 days. A total of 80 (44.7%) patients had a pulmonary medicine consultation. In the pulmonary medicine consultation group versus the no-pulmonary medicine consultation group, there was a significant difference in hospital LOS (4.16 vs. 2.86 days, p value <.0001) and PICU LOS (2.00 vs. 1.00, p value <.0001), escalation of controller medication (66% vs. 21%, p value <.0001), scheduled outpatient pulmonology follow-up (87.5% vs. 45.4%, p value <.0001), and receiving ≥3 courses of systemic steroids in the 12 months after discharge (32.2% vs. 14.7%). There was no difference in attendance of scheduled follow up appointments or in having ≥3 emergency room visits or admissions in the 12 months after discharge. CONCLUSION: Pulmonary medicine consultation during hospital admission may impact management of critical asthma by increasing escalation of controller medication and scheduled outpatient follow up.

US pediatric pulmonology workforce.

AIM: Children with respiratory conditions benefit from care provided by pediatric pulmonologists. As these physicians are a small portion of the overall pediatric workforce, it is necessary to understand the practices and career plans of these specialists. METHODS: An internet survey was developed by the American Academy of Pediatrics Division of Workforce and Medical Education Policy and sent to members of the American Academy of Pediatrics and American College of Chest Physicians who identified as pediatric pulmonary physicians. RESULTS: Responses were received from 485 physicians and were compared to the results of a similar survey done in 1997. Of those completing the survey, 63% were male and 37% female, with increased number of females since the earlier poll. The average calculated age was 56 years. They worked 54 h per week, down from 59 h in the prior survey. Pediatric pulmonologists are overwhelmingly clinicians (92%) with major responsibilities for administration (79%), teaching (78%), and research. Basic science research was rarely reported (7%). Pediatric pulmonologists felt that referrals had become more complicated in the recent past. Nearly all planned to maintain Pediatric Pulmonology Sub-board certification, though one third planned to cut back on clinical workload in the next decade. Many were concerned that the number needed in the profession in a decade would be inadequate with significant concerns about funding for those positions. CONCLUSION: Overall, these results reflect the current state of the workforce and the need to monitor the supply of practitioners in the future.

Guiding Principles for Team-Based Pediatric Care.

The American Academy of Pediatrics (AAP) recognizes that children's unique and ever-changing needs depend on a variety of support systems. Key components of effective support systems address the needs of the child and family in the context of their home and community and are dynamic so that they reflect, monitor, and respond to changes as the needs of the child and family change. The AAP believes that team-based care involving medical providers and community partners (eg, teachers and state agencies) is a crucial and necessary component of providing high-quality care to children and their families. Team-based care builds on the foundation of the medical home by reaching out to a potentially broad array of participants in the life of a child and incorporating them into the care provided. Importantly, the AAP believes that a high-functioning team includes children and their families as essential partners. The overall goal of team-based care is to enhance communication and cooperation among the varied medical, social, and educational partners in a child's life to better meet the global needs of children and their families, helping them to achieve their best potential. In support of the team-based approach, the AAP urges stakeholders to invest in infrastructure, education, and privacy-secured technology to meet the needs of children. This statement includes limited specific examples of potential team members, including health care providers and community partners, that are meant to be illustrative and in no way represent a complete or comprehensive listing of all team members who may be of importance for a specific child and family.

Respiratory outcomes, utilization and costs 12 months following a respiratory syncytial virus diagnosis among commercially insured late-preterm infants.

OBJECTIVES: To determine, among a commercially-insured population of late-preterm infants, utilization of healthcare resources and costs during the 1 year following a diagnosis of respiratory syncytial virus lower respiratory infection (RSV LRI). METHODS: Administrative claims for non-capitated, commercially-insured infants <1 year old were used to identify infants diagnosed with RSV LRI and unspecified bronchiolitis/pneumonia (UBP). Infants were stratified by the setting of diagnosis. Infants without evidence of RSV LRI or UBP were selected as a comparison group. Economic and clinical outcomes were analyzed descriptively using propensity score weighting and logged ordinary least squares models were used to examine the relationship between RSV and costs (adjusted to 2006 USD) incurred within 1 year of RSV LRI. RESULTS: The majority of infants were 3 months or older at the time of RSV LRI or UBP diagnosis. The rate of wheezing was significantly greater for infants in the RSV LRI and UBP cohorts relative to the comparison group (p < 0.001). Infantile asthma rates were 6-9 times higher among RSV LRI and UBP infants than the comparison group. RSV LRI and UBP infants also had significantly more emergency department visits and outpatient visits than the comparison group. The marginal healthcare costs were significantly higher for RSV LRI inpatients ($24,027) and outpatients ($2703) infants than for the comparison group (all p < 0.001). CONCLUSION: Commercially insured late-preterm infants with RSV infection are at high risk for recurrent wheezing and infantile asthma during the 1-year period after the initial episode and impose a significant economic burden to the healthcare system.

Association of RSV lower respiratory tract infection and subsequent healthcare use and costs: a Medicaid claims analysis in early-preterm, late-preterm, and full-term infants.

OBJECTIVE: Healthcare use and costs within 1 year of a respiratory syncytial virus lower respiratory tract infection (RSV-LRI) among Medicaid early-preterm and late-preterm infants compared with full-term infants were evaluated. METHODS: Infants born during 2003-2005 were identified from the Thomson Reuters MarketScan Multi-State Medicaid Database. Infants <1 year of age were grouped based on RSV-LRI and unspecified bronchiolitis/pneumonia (UBP) diagnosis codes and stratified by inpatient or outpatient setting. Infants without RSV-LRI/UBP were selected for comparison. Economic and clinical outcomes were analyzed descriptively; the relationship between RSV-LRI/UBP and costs incurred within 1 year of infection were analyzed using logged ordinary least squares models. Results were stratified by gestational age. RESULTS: Most infants were diagnosed with RSV-LRI/UBP after 90 days of chronologic age. Early-preterm infants had the greatest mean number of inpatient, outpatient, and emergency department visits after an RSV-LRI/UBP episode. The marginal costs among infants with RSV-LRI compared with controls were $34,132 (p < 0.001) and $3869 (p = 0.115) among inpatients and outpatients, respectively. Among late-preterm infants, the marginal costs were $17,465 (p < 0.001) and $2158 (p < 0.001) among inpatients and outpatients, respectively. Full-term infants had the lowest marginal costs (inpatients, $9151 [p < 0.001]; outpatients, $1428 [p < 0.001]). Overall, inpatient infants with RSV-LRI/UBP had higher costs than outpatients, suggesting that increased downstream costs are associated with severity of RSV-LRI/UBP disease. LIMITATIONS: Infants with unknown etiology for bronchiolitis were assigned to the UBP group, which may underestimate the costs of the comparison group. CONCLUSIONS: The burden of RSV-LRI was substantial among early-preterm Medicaid infants. Costs were also higher among late-preterm relative to full-term infants.

Improving care for children with sickle cell disease/acute chest syndrome.

BACKGROUND: Acute chest syndrome (ACS) is a leading cause of hospitalization and death of children with sickle cell disease (SCD). An evidence-based ACS/SCD guideline was established to standardize care throughout the institution in February 2008. However, by the summer of 2009 use of the guideline was inconsistent, and did not seem to have an impact on length of stay. As a result, an implementation program was developed. OBJECTIVE: This quality-improvement project evaluated the influence of the development and implementation of a clinical practice guideline for children with SCD with ACS or at risk for ACS on clinical outcomes. METHODS: Clinical outcomes of 139 patients with SCD were evaluated before and after the development of the implementation program. Outcomes included average length of stay, number of exchange transfusions, average cost per SCD admission, and documentation of the clinical respiratory score and pulmonary interventions. RESULTS: Average length of stay decreased from 5.8 days before implementation of the guideline to 4.1 days after implementation (P = .033). No patients required an exchange transfusion. Average cost per SCD admission decreased from $30 359 before guideline implementation to $22 368. Documentation of the clinical respiratory score increased from 31.0% before implementation to 75.5%, which is an improvement of 44.5% (P < .001). Documentation of incentive spirometry and positive expiratory pressure increased from 23.3% before implementation to 50.4%, which is an improvement of 27.1% (P < .001). CONCLUSIONS: Implementation of a guideline for children with SCD with ACS or at risk for ACS improved outcomes for patients with SCD.

Healthcare costs within a year of respiratory syncytial virus among Medicaid infants.

Limited research exists on the economic impact of respiratory syncytial virus lower respiratory infection (RSV LRI) among vulnerable infant populations. This study evaluated healthcare costs of full-term and late-preterm Medicaid infants with RSV LRI within 1 year of infection. Medicaid administrative claims were used to conduct a retrospective study of infants born 2003-2005. Full-term and late-preterm infants <1 year old were assigned to groups based on RSV LRI and unspecified bronchiolitis/pneumonia (UBP) diagnosis codes and stratified by setting of diagnosis. Infants without evidence of RSV LRI/UBP were selected as a comparison group. Economic and clinical outcomes were analyzed descriptively using propensity score weighting, and logged ordinary least squares models were used to examine relationship between RSV and costs incurred within 1 year of infection. RSV LRI and UBP infants, regardless of gestational age or healthcare setting, were more likely to experience respiratory diagnoses of wheezing and infantile asthma versus comparisons. Adjusted and weighted healthcare costs were significantly higher for all groups of RSV LRI and UBP infants relative to comparison infants (P < 0.001). Among late-preterm infants with inpatient and outpatient RSV, marginal costs compared with controls were $17,465 and $2,158, respectively. Costs for RSV LRI and UBP Medicaid infants are substantial. While much of the costs result from initial RSV episodes, higher post-episode costs and rates of respiratory events, procedures, and medications in RSV and UBP infants versus comparisons indicate long-term economic impact from infection and the impact is greater among late-preterm compared to full-term infants.

Preterm infants with congenital heart disease and bronchopulmonary dysplasia: postoperative course and outcome after cardiac surgery.

OBJECTIVE: Success in treatment of premature infants has resulted in increased numbers of neonates who have bronchopulmonary dysplasia (BPD) and require surgical palliation or repair of congenital heart disease (CHD). We sought to investigate the impact of BPD on children with CHD after heart surgery. METHODS: This was a retrospective, multicenter study of patients who had BPD, defined as being oxygen dependent at 28 days of age with radiographic changes, and CHD and had cardiac surgery (excluding arterial duct ligation) between January 1991 and January 2002. Forty-three infants underwent a total of 52 cardiac operations. The median gestational age at birth was 28 weeks (range: 23-35 weeks), birth weight was 1460 g (range: 431-2500 g), and age at surgery was 2.7 months (range: 1.0-11.6 months). Diagnoses included left-to-right shunts (n = 15), conotruncal abnormalities (n = 13), arch obstruction (n = 6), univentricular hearts (n = 4), semilunar valve obstruction (n = 3), Shone syndrome (n = 1), and cor triatriatum (n = 1). RESULTS: Thirty-day survival was 84% with 6 early and 6 late postoperative deaths. Survival to hospital discharge was 68%. There was 50% mortality for patients with univentricular hearts and severe BPD. The median duration of preoperative ventilation was 76 days (range: 2-244 days) and of postoperative ventilation was 15 days (range: 1-141 days). The median duration of cardiac ICU stay was 7.5 days (range: 1-30 days) and of hospital stay was 115 days (range: 35-475 days). Current pulmonary status includes on room air (n = 14), O2 at home (n = 4), and ventilated at home (n = 4) or in hospital (n = 4), and 5 patients were lost to follow-up. CONCLUSIONS: BPD has significant implications for children who have CHD and undergo cardiac surgery, leading to prolonged ICU and hospital stays, although most survivors are not O2 dependent. Postoperative mortality was highest among patients with univentricular hearts and severe BPD. Optimal timing of surgery and strategies to improve outcome remains to be delineated.

Chronic and recurrent pneumonias in children.

The diagnosis and management of chronic and recurrent pneumonia in children may present a significant challenge for the primary care physician. Successful management depends on a careful evaluation of each episode, with a complete review of all available chest radiographs. Timing, location, and prodromes to recurrence can all provide important clues to the etiology of infection. Infiltrates that recur in a single lobe or segment of the lung may be caused by local airway obstruction, or by anatomic abnormalities of the lung itself. Pneumonias that occur in varied locations, or affect more than one lobe, suggest the presence of a more generalized abnormality, such as swallow dysfunction or aspiration, immunodeficiency or asthma. The pattern, frequency of recurrence, and severity of the infections can guide the practitioner in choosing the diagnostic studies most likely to identify an underlying etiology for recurrent episodes of pneumonia. With diligence and patience, most children with recurrent lower respiratory disease can be treated effectively.
