RESUMO

OBJECTIVE: In 2014, the American Academy of Pediatrics (AAP) changed its policy on the use of respiratory syncytial virus immunoprophylaxis (RSV-IP) so that RSV-IP was no longer recommended for use among infants without other medical conditions born >29 weeks of gestational age (wGA). This study examines 10-year trends in RSV-IP and RSV hospitalizations among term infants and preterm infants born at 29 to 34 wGA, including the 5 RSV seasons before and 5 RSV seasons after the AAP guidance change. STUDY DESIGN: A retrospective observational cohort study of a convenience sample of infants less than 6 months of age during RSV season (November-March) born between July 1, 2008, and June 30, 2019, who were born at 29 to 34 wGA (preterm) or >37 wGA (term) in the IBM MarketScan Commercial and Multi-State Medicaid databases. We excluded infants with medical conditions that would independently qualify them for RSV-IP. We identified RSV-IP utilization along with RSV and all-cause bronchiolitis hospitalizations during each RSV season. A difference-in-difference model was used to determine if there was a significant change in the relative rate of RSV hospitalizations following the 2014 policy change. RESULTS: There were 53,535 commercially insured and 85,099 Medicaid-insured qualifying preterm infants and 1,111,670 commercially insured and 1,492,943 Medicaid-insured qualifying term infants. Following the 2014 policy change, RSV-IP utilization decreased for all infants, while hospitalization rates tended to increase for preterm infants. Rate ratios comparing preterm to term infants also increased. The relative rate for RSV hospitalization for infants born at 29 to 34 wGA increased significantly for both commercially and Medicaid-insured infants (1.95, 95% CI: 1.67-2.27, p <0.001; 1.70, 95% CI: 1.55-1.86, p <0.001, respectively). Findings were similar for all-cause bronchiolitis hospitalizations. CONCLUSION: We found that the previously identified increase in RSV hospitalization rates among infants born at 29 to 34 wGA persisted for at least 5 years following the policy change. KEY POINTS: · Immunoprophylaxis rates decreased after the 2014 American Academy of Pediatrics guidelines update.. · Rate of RSV hospitalization increased among preterm infants after the 2014 AAP guidelines update.. · Increase in RSV hospitalization persisted for at least 5 years after AAP guidelines update..

RESUMO

OBJECTIVE: The aim of this study is to compare outpatient respiratory syncytial virus (RSV) immunoprophylaxis (IP) use and relative RSV hospitalization (RSVH) rates for infants <29 weeks' gestational age (wGA) versus term infants before and after the 2014 American Academy of Pediatrics (AAP) policy change. STUDY DESIGN: Infants were identified in the MarketScan Commercial and Multi-State Medicaid databases. Outpatient RSV IP receipt and relative <29 wGA/term hospitalization risks in 2012 to 2014 and 2014 to 2016 were assessed using rate ratios and a difference-in-difference model. RESULTS: Outpatient RSV IP receipt by infants <29 wGA and aged <3 months in the Commercial and Medicaid populations and those aged 3 to <6 months in the Medicaid population declined after 2014. Relative RSVH risks for infants <29 wGA were numerically greater after 2014, with infants aged <3 months and Medicaid infants experiencing the greatest increases. Difference-in-difference results indicated a significantly increased relative risk of RSVH for infants <29 wGA versus term (both cohorts aged 0 to <6 months) in the Medicaid-insured population (1.68, p = 0.0054). A nonsignificant increase of similar magnitude occurred in the commercially insured population (1.57, p = 0.2867). CONCLUSION: The 2014 policy change was associated with a decrease in RSV IP use and an increase in RSVH risk among otherwise healthy infants <29 wGA.

RESUMO

OBJECTIVES: A "brief resolved unexplained event" refers to sudden alterations in an infant's breathing, color, tone, or responsiveness that prompt the parent or caregiver to seek emergency medical care. A recently published clinical practice guideline encourages discharging many of these infants home from the emergency department if they have a benign presentation. The goal is to avoid aggressive inpatient investigations of uncertain benefit. The present research explored parents' reactions to the prospect of returning home with their infant following such an event. METHODS: The study used qualitative research methods to analyze semistructured, audio-recorded interviews of parents who had witnessed a brief resolved unexplained event between 2011 and 2015 and taken their infant to the emergency department of an academic teaching hospital. RESULTS: A total of 22 parent interviews were conducted. The infants included 8 boys and 14 girls aged 3.6 ± 3.5 months (mean ± SD). Qualitative analysis of interview transcripts revealed a near-universal apprehension about the child's well-being, ambivalence about the best course of action after the evaluation in the emergency department, and need for reassurance about the unlikelihood of a recurrence. Parents did not, however, answer the main research question with a single voice: attitudes toward the return-home scenario ranged from unthinkable to extreme relief. Two-thirds of parents expressed at least some reservations about the idea of returning home. CONCLUSIONS: Successful implementation of the 2016 guideline will require close attention to the parent's point of view. Otherwise, parental resistance is likely to compromise clinicians' best efforts.

RESUMO

OBJECTIVE: To assess the impact of separation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) polymerase chain reaction (PCR)-positive mother-newborn dyads on breastfeeding outcomes. STUDY DESIGN: This observational longitudinal cohort study of mothers with SARS-CoV-2 PCR-and their infants at 3 NYU Langone Health hospitals was conducted between March 25, 2020, and May 30, 2020. Mothers were surveyed by telephone regarding predelivery feeding plans, in-hospital feeding, and home feeding of their neonates. Any change prompted an additional question to determine whether this change was due to coronavirus disease-2019 (COVID-19). RESULTS: Of the 160 mother-newborn dyads, 103 mothers were reached by telephone, and 85 consented to participate. There was no significant difference in the predelivery feeding plan between the separated and unseparated dyads (P = .268). Higher rates of breastfeeding were observed in the unseparated dyads compared with the separated dyads both in the hospital (P < .001) and at home (P = .012). Only 2 mothers in each group reported expressed breast milk as the hospital feeding source (5.6% of unseparated vs 4.1% of separated). COVID-19 was more commonly cited as the reason for change in the separated group (49.0% vs 16.7%; P < .001). When the dyads were further stratified by symptom status into 4 groups-asymptomatic separated, asymptomatic unseparated, symptomatic separated, and symptomatic unseparated-the results remained unchanged. CONCLUSIONS: In the setting of COVID-19, separation of mother-newborn dyads impacts breastfeeding outcomes, with lower rates of breastfeeding both during hospitalization and at home following discharge compared with unseparated mothers and infants. No evidence of vertical transmission was observed; 1 case of postnatal transmission occurred from an unmasked symptomatic mother who held her infant at birth.

RESUMO

OBJECTIVE: This study examined the rate, severity, and cost of respiratory syncytial virus (RSV) hospitalizations among preterm infants 29 to 34 weeks gestational age (wGA) versus term infants before and after a 2014 change in the American Academy of Pediatrics policy for RSV immunoprophylaxis. STUDY DESIGN: Preterm (29-34 wGA) and term infants born from July 2011 to March 2017 and aged < 6 months were identified in a U.S. commercial administrative claims database. RSV hospitalization (RSVH) rate ratios, severity, and costs were evaluated for the 2011 to 2014 and 2014 to 2017 RSV seasons. Postpolicy changes in RSVH risks for preterm versus term infants were assessed with difference-in-difference (DID) modeling to control for patient characteristics and temporal trends. RESULTS: In the DID analysis, prematurity-associated RSVH risk was 55% greater in 2014 to 2017 versus 2011 to 2014 (relative risk = 1.55, 95% confidence interval: 1.10-2.17, p = 0.011). RSVH severity increased among preterm infants after 2014 and was highest among those aged < 3 months. Differences in mean RSVH costs for preterm infants in 2014 to 2017 versus 2011 to 2014 were not statistically significant. CONCLUSION: RSVH risk for preterm versus term infants increased after the policy change, confirming previous national analyses. RSVHs after the policy change were more severe, particularly among younger preterm infants.

RESUMO

OBJECTIVE: The SENTINEL1 observational study characterized confirmed respiratory syncytial virus hospitalizations (RSVH) among U.S. preterm infants born at 29 to 35 weeks' gestational age (wGA) not receiving respiratory syncytial virus (RSV) immunoprophylaxis (IP) during the 2014 to 2015 and 2015 to 2016 RSV seasons. STUDY DESIGN: All laboratory-confirmed RSVH at participating sites during the 2014 to 2015 and 2015 to 2016 RSV seasons (October 1-April 30) lasting ≥24 hours among preterm infants 29 to 35 wGA and aged <12 months who did not receive RSV IP within 35 days before onset of symptoms were identified and characterized. RESULTS: Results were similar across the two seasons. Among infants with community-acquired RSVH (N = 1,378), 45% were admitted to the intensive care unit (ICU) and 19% required invasive mechanical ventilation (IMV). There were two deaths. Infants aged <6 months accounted for 78% of RSVH observed, 84% of ICU admissions, and 91% requiring IMV. Among infants who were discharged from their birth hospitalization during the RSV season, 82% of RSVH occurred within 60 days of birth hospitalization discharge. CONCLUSION: Among U.S. preterm infants 29 to 35 wGA not receiving RSV IP, RSVH are often severe with almost one-half requiring ICU admission and about one in five needing IMV.

RESUMO

OBJECTIVE: This article aims to compare respiratory syncytial virus (RSV) immunoprophylaxis (IP) use and RSV hospitalization rates (RSVH) in preterm and full-term infants without chronic lung disease of prematurity or congenital heart disease before and after the recommendation against RSV IP use in preterm infants born at 29 to 34 weeks' gestational age (wGA). STUDY DESIGN: Infants in commercial and Medicaid claims databases were followed from birth through first year to assess RSV IP and RSVH, as a function of infant's age and wGA. RSV IP was based on pharmacy or outpatient medical claims for palivizumab. RSVH was based on inpatient medical claims with a diagnosis of RSV. RESULTS: Commercial and Medicaid infants 29 to 34 wGA represented 2.9 to 3.5% of all births. RSV IP use in infants 29 to 34 wGA decreased 62 to 95% (p < 0.01) in the 2014-2015 season relative to the 2013-2014 season. Compared with the 2013-2014 season, RSVH increased by 2.7-fold (p = 0.02) and 1.4-fold (p = 0.03) for infants aged <3 months and 29 to 34 wGA in the 2014-2015 season with commercial and Medicaid insurance, respectively. In the 2014-2015 season, RSVH for infants 29 to 34 wGA were two to seven times higher than full-term infants without high-risk conditions. CONCLUSION: Following the 2014 RSV IP guidance change, RSV IP use declined and RSVH increased among infants born at 29 to 34 wGA and aged <3 months.

RESUMO

OBJECTIVE: The objective of this study was to compare risk for respiratory syncytial virus (RSV) hospitalizations (RSVH) for preterm infants 29 to 34 weeks gestational age (wGA) versus term infants before and after 2014 guidance changes for immunoprophylaxis (IP), using data from the 2012 to 2016 RSV seasons. STUDY DESIGN: Using commercial and Medicaid claims databases, infants born between July 1, 2011 and June 30, 2016 were categorized as preterm or term. RSVH during the RSV season (November-March) were identified for infants aged <6 months and rate ratios (RRs) for hospitalization comparing preterm and term infants were calculated. Difference-in-difference models were fit to evaluate the changes in hospitalization risks in preterm versus term infants from 2012 to 2014 seasons to 2014 to 2016 seasons. RESULTS: In all seasons, preterm infants had higher RSVH rates than term infants. Seasonal RRs prior to the guidance change for preterm wGA categories versus term infants ranged from 1.6 to 3.4. After the guidance change, the seasonal RRs ranged from 2.6 to 5.6. In 2014 to 2016, the risk associated with prematurity of 29 to 34 wGA versus term was significantly higher than in 2012 to 2014 (P<0.0001 for commercial and Medicaid samples). CONCLUSION: In infants aged <6 months, the risk for RSVH for infants 29 to 34 wGA compared with term infants increased significantly after the RSV IP recommendations became more restrictive.

RESUMO

Objective SENTINEL1 characterized U.S. preterm infants 29 to 35 weeks' gestational age (wGA) < 12 months old hospitalized for laboratory-confirmed respiratory syncytial virus (RSV) disease and not receiving RSV immunoprophylaxis during the 2014 to 2015 RSV season. Study Design This is a noninterventional, observational, cohort study. Results A total of 702 infants were hospitalized with community-acquired RSV disease, of whom an estimated 42% were admitted to the intensive care unit (ICU) and 20% required invasive mechanical ventilation (IMV). Earlier gestational age and younger chronologic age were associated with an increased frequency of RSV-confirmed hospitalization (RSVH), ICU admission, and IMV. Among infants 29 to 32 wGA and < 3 months of age, 68% required ICU admission and 44% required IMV. One death occurred of an infant 29 wGA. Among the 212 infants enrolled for in-depth analysis of health care resource utilization, mean and median RSVH charges were $55,551 and $27,461, respectively, which varied by intensity of care required. Outpatient visits were common, with 63% and 62% of infants requiring visits before and within 1 month following the RSVH, respectively. Conclusion Preterm infants 29 to 35 wGA are at high risk for severe RSV disease, which imposes a substantial health burden, particularly in the first months of life.

RESUMO

BACKGROUND: Infection with respiratory syncytial virus (RSV) is common among young children insured through Medicaid in the United States. Complete and timely dosing with palivizumab is associated with lower risk of RSV-related hospitalizations, but up to 60% of infants who receive palivizumab in Medicaid population do not receive full prophylaxis. The purpose of this study was to evaluate the association of partial palivizumab prophylaxis with the risk of RSV hospitalization among high-risk Medicaid-insured infants. METHODS: Claims data from 12 states during 6 RSV seasons (October 1st to April 30th in the first year of life in 2003-2009) were analyzed. Inclusion criteria were birth hospital discharge before October 1st, continuous insurance eligibility from birth through April 30th, ≥ one palivizumab administration from August 1st to end of season, and high-risk status (≤34 weeks gestational age or chronic lung disease of prematurity [CLDP] or hemodynamically significant congenital heart disease [CHD]). Fully prophylaxed infants received the first palivizumab dose by November 30th with no gaps >35 days up to the first RSV-related hospitalization or end of follow-up. All other infants were categorized as partially prophylaxed. RESULTS: Of the 8,443 high-risk infants evaluated, 67% (5,615) received partial prophylaxis. Partially prophylaxed infants were more likely to have RSV-related hospitalization than fully prophylaxed infants (11.7% versus 7.9%, p< 0.001). RSV-related hospitalization rates ranged from 8.5% to 24.8% in premature, CHD, and CLDP infants with partial prophylaxis. After adjusting for potential confounders, logistic regression showed that partially prophylaxed infants had a 21% greater odds of hospitalization compared with fully prophylaxed infants (odds ratio 1.21, 95% confidence interval 1.09-1.34). CONCLUSIONS: RSV-related hospitalization rates were significantly higher in high-risk Medicaid infants with partial palivizumab prophylaxis compared with fully prophylaxed infants. These findings suggest that reduced and/or delayed dosing is less effective.

RESUMO

The efforts to prevent RSV infection in infants span over half a century. RSV vaccine development began in the 1960s, and it confronted a significant disappointment after testing a formalin inactivated RSV (FI RSV) vaccine candidate. This inactivated RSV vaccine was not protective. A large number of the vaccinated RSV naïve children, when subsequently exposed to natural RSV infection from wild type virus in the community, developed severe lung inflammation termed enhanced respiratory disease. This resulted in a halt in RSV vaccine development. In the 1990s, attention turned to the potential for passive protection against severe RSV disease with immunoglobulin administration. This led to studies on using standard intravenous immunoglobulins in high-risk infants, followed by high-titer RSV immunoglobulin preparation and, subsequently, the development of RSV monoclonal antibodies. Over the past 25 years, palivizumab has been recognized as a safe and effective monoclonal antibody as a prevention strategy for RSV in high-risk children. Its high cost and need for monthly administration, however, has hindered its use to ~2% of the birth cohort, neglecting the vast majority of newborns, including healthy full-term infants who comprise the largest portion of RSV hospitalizations and the greatest part of the burden of RSV disease. Still these efforts, helped pave the way for the present advances in RSV prevention that hold promise for mitigating severe RSV disease for all infants.

RESUMO

BACKGROUND: In the United States, uptake of human papillomavirus (HPV) vaccination has been exceptionally low as compared with other vaccines. During the coronavirus disease (COVID-19) pandemic, routine vaccinations were deferred or delayed, further exacerbating HPV vaccine hesitancy. The specific effect of the pandemic on HPV vaccination rates in the United States has not been yet described. METHODS: We aimed to determine the percentage of children achieving full HPV vaccination (2 doses) by age 15 years and to compare prepandemic to pandemic rates of HPV vaccination at pediatric practices across our institution. A retrospective chart review was performed to compare HPV vaccination rates in the "prepandemic" and "pandemic" periods for all children 9 through 14 years of age. Additionally, peaks in COVID-19 positivity were compared with HPV vaccination rates. RESULTS: Of children 9-14 years old, 49.3% received at least 1 dose of HPV vaccine in the prepandemic period, compared with 33.5% during the pandemic ( P < 0.0001). Only 33.5% of patients received the full 2-dose series of HPV prepandemic, compared with 19.0% of patients during the pandemic ( P < 0.0001). When COVID-19 positivity rates peaked, HPV vaccination also declined. CONCLUSIONS: The issue of low HPV vaccination rates was amplified due to the COVID-19 pandemic, as illustrated by the correlation between peaks in COVID-19 positivity and low rates of HPV vaccination.
