Variation in care for inpatients with avoidant restrictive food intake disorder leads to development of a novel inpatient clinical pathway to standardize care.

INTRODUCTION: There is limited evidence to guide management of patients with avoidant restrictive food intake disorder (ARFID) admitted for medical stabilization. We describe variations in inpatient care which led to the development of a multidisciplinary inpatient clinical pathway (ICP) to provide standardized management and examine differences after the ICP was implemented. METHODS: A retrospective review of patients with ARFID admitted to Adolescent Medicine, Gastroenterology, and General Pediatrics at a single academic center was conducted. We compare hospital utilization and use of consulting services during the pre-ICP (2015-2017) and post-ICP (2018-2020) periods. RESULTS: 110 patients were admitted with ARFID (n = 57 pre- vs. n = 53 post-ICP). Most presented with moderate/severe malnutrition (63% pre vs. 81% post; p = 0.11) and co-morbid anxiety and/or depression (74% pre vs. 92% post; p = 0.01). There was some variation in use of enteral tube feeding by service in both periods (p = 0.76 and p = 0.38, respectively), although overall use was consistent between periods (46% pre vs. 58% post; p = 0.18). Pre-ICP, use of the restrictive eating disorder protocol differed across services (p < 0.001), with only AM using it. Overall, utilization of the restrictive eating disorder protocol decreased from 16% pre-ICP to 2% post-ICP (p = 0.02). There was variation by service in psychiatry/psychology (range 82-100% by service; p = 0.09) and social work consultations (range 17-71% by service; p = 0.001) during the pre-ICP period, though variation was reduced in the post-ICP period (p = 0.99 and p = 0.05, respectively). Implementation of the ICP led to improvements in these consultative services, with all patients in the post-ICP period receiving psychiatry/psychology consultation (p = 0.05) and an increase in social work consults from 44 to 64% (p = 0.03). Nutrition consults were consistently utilized in both periods (98% pre vs. 100% post; p = 0.33). CONCLUSION: The ICP was developed to standardize inpatient medical stabilization for patients with ARFID. In this single center study, implementation of the ICP increased standardized care for inpatients with ARFID with variation in care reduced: there were improvements in the use of consulting services and a reduction in the use of the restrictive eating disorder protocol. The ICP demonstrates the potential to further standardize and improve care over time.

There is limited evidence to guide management of children and adolescents with Avoidant Restrictive Food Intake Disorder (ARFID) admitted for medical stabilization. The study describes the variation in inpatient care for ARFID, which led to the development of a multidisciplinary standardized inpatient clinical pathway (ICP). The ICP centers the experience of the patient and family with an emphasis on biopsychosocial support. Implementation of the ICP increased standardized care for inpatients with ARFID with variation in care reduced: There were improvements in the use of psychiatry/psychology and social work consulting services and a reduction in the use of the restrictive eating disorder protocol. Future research is needed to better understand the impact of the inpatient clinical pathway to improve care over time.

Increased Pediatric Respiratory Syncytial Virus Case Counts Following the Emergence of SARS-CoV-2 Can Be Attributed to Changes in Testing.

BACKGROUND: Respiratory syncytial virus (RSV) circulation dropped markedly early in the COVID-19 pandemic, followed by a resurgence with heightened case counts. The "immunity debt" hypothesis proposes that the RSV-naїve pediatric population increased during the period of low transmission. However, the evidence supporting this hypothesis is limited, and the role of changing testing practices in the perceived surge has not been comprehensively evaluated. METHODS: We conducted a multicenter, retrospective analysis of 342 530 RSV encounters and 980 546 RSV diagnostic tests occurring at 32 US pediatric hospitals in 2013-2023. We used interrupted time series analysis to estimate pandemic-associated changes in RSV patient and test volume and to quantify changes in the proportions of patients requiring hospitalization, intensive care, or mechanical ventilation. We quantified the fraction of the shifts in case counts and in the age of diagnosed patients attributable to changes in testing. RESULTS: RSV patient volume increased 2.4-fold (95% confidence interval [CI]: 1.7, 3.5) in 2021-2023 relative to the pre-pandemic phase and was accompanied by an 18.9-fold increase (95% CI: 15.0, 23.9) in RSV test volume. Shifts in patient volume and in patient age were largely attributable to increased testing. The proportions of patients with RSV that required hospitalization, intensive care, or mechanical ventilation declined significantly across all patient age groups. CONCLUSIONS: A surge in RSV testing, rather than in viral circulation, likely underlies the increased case counts observed in 2021-2023. These findings warrant a critical assessment of the immunity debt hypothesis and highlight the importance of considering the testing denominator when surveillance strategies are dynamic.

Telemedicine for Adolescent and Young Adult Long-Acting Reversible Contraception Post-insertion Visits: Outcomes over 1 Year.

STUDY OBJECTIVE: Telemedicine for long-acting reversible contraception (LARC) care is understudied given the rapid implementation of these services in response to the COVID-19 pandemic. We compared outcomes over 1 year of adolescents and young adults (AYAs) attending a LARC post-insertion visit via telemedicine vs in person. DESIGN: Longitudinal cohort study. SETTING: Four academic adolescent medicine clinics in the United States. PARTICIPANTS: AYAs (ages 13-26 years) who received LARC between 4/1/20 and 3/1/21 and attended a post-insertion visit within 12 weeks. INTERVENTIONS: none. MAIN OUTCOME MEASURES: Outcomes over 1 year were compared between AYAs who completed this visit via telemedicine vs in person. We analyzed the data using descriptive statistics, bivariate analyses, and regression models. RESULTS: Of 194 AYAs (ages 13.9-25.7 years) attending a post-insertion visit, 40.2% utilized telemedicine. Menstrual management (odds ratio (OR) = 1.02; confidence interval (CI): 0.40-2.60), acne management (P = .28), number of visits attended (relative risk (RR) = 1.08; CI: 0.99-1.19), and LARC removal (P = .95) were similar between groups. AYAs attending via telemedicine were less likely than those attending in person to have STI testing (P = .001). Intrauterine device expulsion or malposition and arm symptoms with implant in situ were rare outcomes in both groups. CONCLUSION: Roughly 40% of AYAs attended a post-insertion visit via telemedicine during the first year of the COVID-19 pandemic and had similar 1-year outcomes as those attending in person. The decreased likelihood of STI testing for those using telemedicine highlights the need to provide alternative options, when indicated, such as asynchronous or home testing. Our results support the use of telemedicine for AYA LARC post-insertion care and identify potential gaps in telemedicine care which can help improve clinic protocols.

Pediatric hospital utilization for patients with avoidant restrictive food intake disorder.

BACKGROUND: Avoidant restrictive food intake disorder (ARFID) is a relatively new feeding and eating disorder added to the DSM-5 in 2013 and ICD-10 in 2018. Few studies have examined hospital utilization for patients with ARFID specifically, and none to date have used large administrative cohorts. We examined inpatient admission volume over time and hospital utilization and 30-day readmissions for patients with ARFID at pediatric hospitals in the United States. METHODS: Using data from the Pediatric Health Information System (PHIS), we identified inpatient admissions for patients with ARFID (by principal International Classification of Diseases, 10th Revision, ICD-10 diagnosis code) discharged October 2017-June 2022. We examined the change over time in ARFID volume and associations between patient-level factors (e.g., sociodemographic characteristics, co-morbid conditions including anxiety and depressive disorders and malnutrition), hospital ARFID volume, and hospital utilization including length of stay (LOS), costs, use of enteral tube feeding or GI imaging during admission, and 30-day readmissions. Adjusted regression models were used to examine associations between sociodemographic and clinical factors on LOS, costs, and 30-day readmissions. RESULTS: Inpatient ARFID volume across n = 44 pediatric hospitals has increased over time (ß = 0.36 per month; 95% CI 0.26-0.46; p < 0.001). Among N = 1288 inpatient admissions for patients with ARFID, median LOS was 7 days (IQR = 8) with median costs of $16,583 (IQR = $18,115). LOS and costs were highest in hospitals with higher volumes of ARFID patients. Younger age, co-morbid conditions, enteral feeding, and GI imaging were also associated with LOS. 8.5% of patients were readmitted within 30 days. In adjusted models, there were differences in the likelihood of readmission by age, insurance, malnutrition diagnosis at index visit, and GI imaging procedures during index visit. CONCLUSIONS: Our results indicate that the volume of inpatient admissions for patients with ARFID has increased at pediatric hospitals in the U.S. since ARFID was added to ICD-10. Inpatient stays for ARFID are long and costly and associated with readmissions. It is important to identify effective and efficient treatment strategies for ARFID in the future.

Recent studies indicate that Avoidant Restrictive Food Intake Disorder (ARFID) is a complex feeding and eating disorder often diagnosed in younger children. To date, there are no large studies using administrative data to examine hospital utilization or costs among patients with ARFID. In a geographically diverse cohort of pediatric hospitals in the United States, we found inpatient admissions for ARFID have increased over time and that ARFID is associated with long, costly stays and readmissions which has important implications for identifying efficient treatment strategies. Future studies are needed to explore effective and efficient treatment strategies and prevent readmissions in this patient population.

Increased pediatric RSV case counts following the emergence of SARS-CoV-2 are attributable to increased testing.

Background: The incidence of respiratory syncytial virus (RSV) dropped markedly early in the COVID-19 pandemic, followed by a resurgence with heightened case counts. The "immunity debt" hypothesis proposes that the RSV-naive pediatric population increased during the period of low transmission, resulting in a subsequent increased risk of infection. However, the evidence supporting this hypothesis is limited, and no studies have comprehensively evaluated the role of changing respiratory viral testing practices in the perceived surge. Methods: We conducted a multicenter, retrospective analysis of 342,530 RSV encounters and 980,546 RSV diagnostic tests occurring at 32 United States pediatric hospitals between 2013 and 2023. We used interrupted time series analysis to estimate pandemic-associated changes in RSV patient and testing volume, and to quantify changes in the proportions of patients admitted from the emergency department (ED), admitted to the intensive care unit (ICU), and receiving mechanical ventilation. We quantified the fraction of the observed shifts in case counts and in the age of diagnosed patients attributable to changes in RSV testing practices. Finally, we analyzed 524,404 influenza virus encounters and 1,768,526 influenza diagnostic tests to address the specificity of the findings to RSV. Findings: RSV patient volume increased 2.4-fold (95% CI: 1.7, 3.5) in 2021-2023 relative to the pre-pandemic phase, and was accompanied by an 18.9-fold increase (95% CI: 15.0, 23.9) in RSV test volume. Over two-thirds of the apparent shifts in patient volume and in patient age were attributable to increased testing, which was concentrated among older pediatric patients. The proportions of patients with RSV requiring hospitalization, intensive care, or mechanical ventilation declined significantly across all patient age groups. These declines were not observed for patients with influenza virus. Interpretation: A surge in RSV testing, rather than in viral circulation, likely underlies the increased case counts observed in 2021-2023. We identify expected consequences of increased testing, including the diagnosis of less severe cases and a shift in the patient age distribution. These findings warrant a critical assessment of the immunity debt hypothesis, while highlighting the importance of considering the testing denominator when surveillance strategies are dynamic.

Features of acute COVID-19 associated with post-acute sequelae of SARS-CoV-2 phenotypes: results from the IMPACC study.

Post-acute sequelae of SARS-CoV-2 (PASC) is a significant public health concern. We describe Patient Reported Outcomes (PROs) on 590 participants prospectively assessed from hospital admission for COVID-19 through one year after discharge. Modeling identified 4 PRO clusters based on reported deficits (minimal, physical, mental/cognitive, and multidomain), supporting heterogenous clinical presentations in PASC, with sub-phenotypes associated with female sex and distinctive comorbidities. During the acute phase of disease, a higher respiratory SARS-CoV-2 viral burden and lower Receptor Binding Domain and Spike antibody titers were associated with both the physical predominant and the multidomain deficit clusters. A lower frequency of circulating B lymphocytes by mass cytometry (CyTOF) was observed in the multidomain deficit cluster. Circulating fibroblast growth factor 21 (FGF21) was significantly elevated in the mental/cognitive predominant and the multidomain clusters. Future efforts to link PASC to acute anti-viral host responses may help to better target treatment and prevention of PASC.

Adolescent and young adult long-acting reversible contraception post-insertion visit attendance before and after COVID-19.

OBJECTIVES: Widespread use of telemedicine for contraceptive care, including long-acting reversible contraception (LARC), was adopted in the United States in response to the COVID-19 pandemic. Given the rapid implementation of these services, little is known about the use of telemedicine for adolescent and young adult (AYA) contraceptive care. This study examined the routine use of telemedicine for LARC post-insertion care by comparing visit attendance between AYAs receiving LARC before and after the COVID-19 pandemic onset. METHODS: This analysis included LARC insertions 3/1/19-11/30/19 (pre-pandemic onset cohort) and 4/1/20-12/31/20 (post-pandemic onset cohort) from three Adolescent Medicine subspecialty clinics in the United States. De-identified data were collected via review of the electronic health record. Descriptive statistics, χ2 tests, and t-tests described and compared groups. Adjusted logistic regression models examined factors associated with attending a post-insertion visit and attending this visit via telemedicine. RESULTS: This analysis included 525 LARC insertions (279 pre- and 246 post-pandemic onset). The proportion of AYAs attending a post-insertion visit increased after the COVID-19 pandemic onset (pre 30 % vs. post 46 %; p≤0.001). Adjusted models revealed that the post-pandemic onset cohort was nearly twice as likely to attend a post-insertion visit as the pre-pandemic onset cohort (OR=1.90; 95 % CI=1.68-2.15). Of those attending this visit in the post-pandemic onset cohort (n=112), 42 % utilized telemedicine. CONCLUSIONS: AYAs were more likely to attend post-insertion visits after the COVID-19 pandemic onset than before. Telemedicine may have influenced this change in visit attendance.

Enhancing Pressure Injury Surveillance Using Natural Language Processing.

OBJECTIVE: This study assessed the feasibility of nursing handoff notes to identify underreported hospital-acquired pressure injury (HAPI) events. METHODS: We have established a natural language processing-assisted manual review process and workflow for data extraction from a corpus of nursing notes across all medical inpatient and intensive care units in a tertiary care pediatric center. This system is trained by 2 domain experts. Our workflow started with keywords around HAPI and treatments, then regular expressions, distributive semantics, and finally a document classifier. We generated 3 models: a tri-gram classifier, binary logistic regression model using the regular expressions as predictors, and a random forest model using both models together. Our final output presented to the event screener was generated using a random forest model validated using derivation and validation sets. RESULTS: Our initial corpus involved 70,981 notes during a 1-year period from 5484 unique admissions for 4220 patients. Our interrater human reviewer agreement on identifying HAPI was high ( κ = 0.67; 95% confidence interval [CI], 0.58-0.75). Our random forest model had 95% sensitivity (95% CI, 90.6%-99.3%), 71.2% specificity (95% CI, 65.1%-77.2%), and 78.7% accuracy (95% CI, 74.1%-83.2%). A total of 264 notes from 148 unique admissions (2.7% of all admissions) were identified describing likely HAPI. Sixty-one described new injuries, and 64 describe known yet possibly evolving injuries. Relative to the total patient population during our study period, HAPI incidence was 11.9 per 1000 discharges, and incidence rate was 1.2 per 1000 bed-days. CONCLUSIONS: Natural language processing-based surveillance is proven to be feasible and high yield using nursing handoff notes.

Continuation rates of hormonal intrauterine devices in adolescents and young adults when placed for contraceptive and non-contraceptive indications.

OBJECTIVE: This study aimed to estimate and compare continuation rates of hormonal intrauterine devices (IUDs) when placed for contraceptive or menstrual management indications in adolescents and young adults. STUDY DESIGN: We conducted a secondary analysis of a prospectively collected database of all hormonal IUD insertions from January 1, 2017 through December 31, 2020, with at least 1-year follow-up, across four Adolescent Medicine practices. IUD insertions without known indication were excluded. RESULTS: A total of 936 IUD insertions were attempted, 45% for contraception only, 18% for menstrual management only, and 37% for both indications. Insertion was successful in 868 (93%) attempts, and success did not differ by indication (p = 0.74). The mean age at insertion was 18.9 years (SD = 2.4 years), with no difference by indication. Of the completed insertions, 650 (75%) had at least one follow-up during the data analysis period. Excluding those without follow-up, the overall continuation rates were 77% at 1 year, 66% at 2 years, and 54% at 3 years. While continuation rates did not differ by indication at 1 year, at 3 years, continuation was highest among those who sought the device for menstrual management only (contraception = 53%, menstrual = 57%, both = 53%, p < 0.01) Malposition was rare (4.0%), as was device expulsion (2.5%), and these did not differ by indication. CONCLUSION: IUD continuation rates were high among adolescents and young adults and did not significantly differ when placed for contraceptive or non-contraceptive indication in the first year of use. IMPLICATIONS: Adolescents and young adults may seek the hormonal IUD for contraception and/or menstrual management. Our study found that IUD continuation rates were high at 1 year regardless of the indication for utilization.

Incidence of Hospital-Acquired Conditions During Pediatric Clinical Research Inpatient Hospitalizations: A Matched Cohort Study.

OBJECTIVES: In this matched cohort study using data from pediatric hospitals, we compared the incidence of hospital-acquired conditions (HACs) during clinical research hospitalizations to nonresearch hospitalizations. METHODS: Using Pediatric Health Information System data for inpatient discharges January 2017-June 2022, we matched research hospitalizations (identified by International Classification of Diseases, Tenth Revision, diagnosis code) to nonresearch hospitalizations within hospital on age (±3 y), sex, discharge year (±2), and All Patients Refined Diagnosis Related Groups classification, severity of illness (±1), and risk of mortality (±1). We calculated the incidence (per 1000 discharges) and incidence rate (per 10,000 patient days) of HAC identified by International Classification of Diseases, Tenth Revision, codes and compare research versus nonresearch using logistic and Poisson regression, accounting for matching using generalized estimating equations and adjusting for sociodemographic factors and hospital utilization. RESULTS: We matched 7000 research hospitalizations to 26,447 nonresearch from 28 hospitals. Median age was 6.0 years (interquartile range, 10.6 y). Median length of stay was 4.0 days (interquartile range, 11.0 days) with longer stays among research hospitalizations ( P < 0.001). Incidence of HAC among research hospitalizations was 13.1 versus 7.2 per 1000 for nonresearch ( P < 0.001) and incidence rate 6.7 versus 4.5 per 10,000 patient days. Adjusting for sociodemographic and clinical factors, research stays had 1.65 times the odds of any HAC (95% confidence interval, 1.27-2.16; P < 0.001) and 1.38 times the incidence rate (95% confidence interval, 1.09-1.75; P = 0.009). CONCLUSIONS: Our findings indicate that pediatric research hospitalizations are more likely to experience HACs compared with nonresearch hospitalizations. These findings have important safety implications for pediatric inpatient clinical research that warrant further study.

Long-acting reversible contraception in gender-diverse adolescents and young adults: Outcomes from a multisite collaborative.

OBJECTIVES: This study aimed to describe the clinical experience of gender-diverse adolescents and young adults receiving long-acting reversible contraception (LARC). STUDY DESIGN: This was a secondary analysis of prospectively collected quality improvement data among gender-diverse adolescents and young adults receiving LARC in four adolescent medicine clinics. RESULTS: Most attempted insertions (59/63) were successful. A majority (54%) chose LARC for both contraception and menstrual management. Pelvic pain/cramping and unsatisfactory bleeding were reported side effects. One known expulsion and six known LARC removals occurred. CONCLUSIONS: Gender-diverse adolescents and young adults had high rates of successful LARC insertion and demonstrated a side effect profile similar to a broader adolescent and young adult population seeking LARC care. IMPLICATIONS: LARC is an important and well-tolerated method of menstrual management and contracention in gender-diverse adolescents and young adults, although more investigation is needed to understand how gender-affirming testosterone therapy may impact the LARC experience in this population.

Adolescent individual, school, and neighborhood influences on young adult diabetes risk.

Using data from the National Longitudinal Study of Adolescent to Adult Health (Add Health), this study examines the association between adolescent school and neighborhood contexts and the likelihood of diabetes in young adulthood. We apply cross-classified multi-level modeling (CCMM) techniques to examine the simultaneous influence of non-nested school and neighborhood contexts as well as individual, school, and neighborhood-level factors (N = 14,041 participants from 128 schools, 1933 neighborhoods). Our findings suggest that individual-level factors are most associated with young adult diabetes, with small contributions from school and neighborhood factors and a small proportion of the variation explained by school and neighborhood contexts.

Multi-omic longitudinal study reveals immune correlates of clinical course among hospitalized COVID-19 patients.

The IMPACC cohort, composed of >1,000 hospitalized COVID-19 participants, contains five illness trajectory groups (TGs) during acute infection (first 28 days), ranging from milder (TG1-3) to more severe disease course (TG4) and death (TG5). Here, we report deep immunophenotyping, profiling of >15,000 longitudinal blood and nasal samples from 540 participants of the IMPACC cohort, using 14 distinct assays. These unbiased analyses identify cellular and molecular signatures present within 72 h of hospital admission that distinguish moderate from severe and fatal COVID-19 disease. Importantly, cellular and molecular states also distinguish participants with more severe disease that recover or stabilize within 28 days from those that progress to fatal outcomes (TG4 vs. TG5). Furthermore, our longitudinal design reveals that these biologic states display distinct temporal patterns associated with clinical outcomes. Characterizing host immune responses in relation to heterogeneity in disease course may inform clinical prognosis and opportunities for intervention.

Assessment of Patients With ARFID Presenting to Multi-Disciplinary Tertiary Care Program.

There are no standard assessment approaches for Avoidant Restrictive Food Intake Disorder (ARFID). We describe our approach to multidisciplinary assessment after assessing more than 550 patients with ARFID. We collected online survey (ARFID-specific instruments, measures of anxiety, depression) measures. Electronic medical record data (mental health and gastrointestinal diagnoses, micronutrient and bone density assessments, and growth parameters) were extracted for the 239 patients with ARFID seen between 2018 and 2021 with both parent and patient responses to online surveys. We identified 5 subtypes/combinations of subtypes: low appetite; sensory sensitivity; fear + sensory sensitivity; fear + low appetite; fear + sensory sensitivity + low appetite. Those with appetite-only subtype had higher mean age (14.0 years, P < 0.01) and the lowest average body mass index z score (-1.74, P < 0.01) compared to other subtypes. Our experience adds to understanding of clinical presentations in patients with ARFID and may aid in assessment formulation.

Volume and Severity of Pediatric COVID-19 Hospitalizations in the United States.

OBJECTIVES: Using administrative data from pediatric hospitals in the United States, we examined trends in coronavirus disease 2019 (COVID-19) hospitalizations and severity of disease among children. METHODS: We extracted data from the Pediatric Health Information System for hospitalized patients less than 12 years old with COVID-19 (identified by primary or secondary International Classification of Diseases-10 diagnosis code U07.1) admitted from April 2020 to August 2022. We examined weekly trends in COVID hospitalization volume overall and by ICU utilization as a measure of severe disease and by COVID diagnosis hierarchy (primary versus secondary) as a proxy for incidental admissions. We estimated the annualized trend in the ratio of hospitalizations requiring, versus not requiring, ICU care and the trend in ratio of hospitalizations with a primary versus secondary COVID diagnosis. RESULTS: We included 38 160 hospitalizations across 45 hospitals. Median age was 2.4 years (interquartile range = 0.7-6.6). Median length of stay was 2.0 days (interquartile range = 1-4). ICU-level care was required for 18.9% and 53.8% had a primary diagnosis of COVID-19. The ratio of ICU to non-ICU admissions declined by 14.5% annually (95% confidence interval: -21.7% to -7.26%; P < .001), whereas the ratio of primary to secondary diagnosis was stable (11.7% annually; 95% confidence interval: -8.83% to 32.4%; P = .26). CONCLUSIONS: Periodic increases in pediatric COVID-19 hospitalizations with are evident. However, there is no evidence of corresponding increase in severity of illness that may provide context for recent reports of increasing pediatric COVID hospitalizations in addition to health policy implications.

Contraceptive Implant-Associated Bleeding in Adolescent/Young Adult Clinical Practice: Associated Factors, Management, and Rates of Discontinuation.

PURPOSE: To identify factors associated with bothersome implant-associated uterine bleeding, and to evaluate the impact of bleeding management on implant discontinuation. METHODS: We analyzed a quality improvement database of implant insertions (n = 825) at three adolescent/young adult programs and described individuals with and without reported bothersome bleeding. We utilized logistic regression to assess for factors associated with bleeding. RESULTS: Implant recipient mean age was 18.9 ± 2.6 years, and 27% reported having subsequent bothersome uterine bleeding. Recipients had increased odds of reporting such bleeding if they had previously irregular menses (odds ratio [OR] = 1.36; 95% confidence interval [CI]: 1.11-1.68 irregular and infrequent, OR = 1.41; 95% CI: 1.07-1.86 irregular and frequent) or sought the implant for menstrual management purposes exclusively (OR = 1.67; 95% CI 1.42-1.96) or in combination with contraceptive need (OR 1.65; 95%: CI 1.57-1.72). Prior use of the progestin injection or implant was associated with lower odds of subsequent bleeding report (OR = 0.63; 95% CI: 0.54-0.73; OR = 0.54; 95% CI: 0.39-0.75, respectively). Medication management of bleeding was associated with the likelihood of implant discontinuation at 1 year compared to those with untreated bleeding (hazard ratio 1.98 times, 95% CI: 1.39-2.81). The implant was continued for 3 years in over 50% of recipients with ever-managed bothersome bleeding. DISCUSSION: Individuals with historically irregular menses and those seeking the implant for menstrual management more often reported bothersome bleeding. Treating such bleeding with medication was associated with higher 1-year discontinuation rates, although many continued implant use for 3 years. Such findings may influence implant preinsertion counseling and/or postinsertion bleeding management.

Association between pharmacologic treatment and hospital utilization at birth among neonatal opioid withdrawal syndrome mother-infant dyads.

OBJECTIVE: We linked mother-baby dyads to explore associations between maternal medication-assisted therapy (MAT) and infants' pharmacologic treatment on birth hospital utilization for infants with NOWS. METHODS: We extracted singleton infant and maternal delivery discharges from PHIS hospitals with large volumes of deliveries for 2016-2019. We matched newborns with NOWS to maternal delivery discharges by hospital, day of birth, mode of delivery, and ZIP code. We examined the association between maternal MAT, infants' pharmacologic treatment, and hospital utilization at birth. RESULTS: We included N = 146 mother-baby dyads from six hospitals (74% match rate). Among matched dyads, 51% received maternal MAT, 60% pharmacotherapy (37% both). Infants treated non-pharmacologically and born to mothers receiving MAT had the shortest stays vs. infants without pharmacotherapy or MAT (RR = 0.29; 95% CI: 0.25-0.35). CONCLUSIONS: These findings underscore the importance of adequate perinatal treatment for opioid use disorder to improve outcomes for mothers and infants with opioid exposure.

Emergency Department Visits and Hospitalizations for Eating Disorders During the COVID-19 Pandemic.

BACKGROUND AND OBJECTIVES: Recent studies have reported increasing eating disorder incidence and severity following the coronavirus disease 2019 (COVID-19) pandemic. In a diverse cohort of pediatric hospitals, we examined trends in the volume of emergency visits and inpatient admissions for eating disorders before and during the pandemic. METHODS: We examined monthly trends in volume of patients with eating disorders (identified by principal International Classification of Diseases, 10th Revision, diagnosis codes) across 38 hospitals in the Pediatric Health Information System pre- (January 2018-March 2020) and post-COVID-19 onset (April 2020-June 2022). Using interrupted time series analysis, we examined the pre- and post monthly trends in eating disorder emergency and inpatient volume. RESULTS: Before the pandemic, eating disorder emergency visit volume was increasing by 1.50 visits per month (P = .006), whereas in the first year postonset, visits increased by 12.9 per month (P < .001), followed by a 6.3 per month decrease in the second year postonset (P < .001). Pre-COVID-19, eating disorder inpatient volume was increasing by 1.70 admissions per month (P = .01). In the first year postonset, inpatient volume increased by 11.9 per month (P < .001), followed by a 7.6 per month decrease in the second year postonset (P < .001). CONCLUSIONS: The volume of patients seeking emergency and inpatient eating disorder care at pediatric hospitals has increased dramatically since the pandemic onset and has not returned to prepandemic levels despite a decline in the second year postonset, with important implications for hospital capacity.
