Telemedicine for adolescent and young adult long-acting reversible contraception post-insertion visits: outcomes over 1 year

OBJECTIVES

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 versus in person.

STUDY DESIGN

We included AYAs (ages 13-26 years) who received LARC between 4/1/20-3/1/21 and attended a post-insertion visit within 12 weeks. Outcomes over 1 year were compared between AYAs who completed this visit via telemedicine versus 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 (OR = 1.02, CI: 0.40-2.60), acne management (p = .28), number of visits attended (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.

IMPLICATIONS

Our results support the use of telemedicine for AYA LARC post-insertion care given similar clinical outcomes and healthcare utilization for LARC-related concerns over 1 year as in-person visits. Furthermore, our results identify STI testing as a potential gap in telemedicine care which can help inform and improve clinic protocols.

Increased Pediatric Respiratory Syncytial Virus Case Counts Following the Emergence of Severe Acute Respiratory Syndrome Coronavirus 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.

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 (β = 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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Telemedicine for Adolescent and Young Adult Long-Acting Reversible Contraception Follow-Up Care amidst a Global Pandemic

STUDY OBJECTIVE

To describe adolescent and young adult (AYA) long-acting reversible contraception (LARC) follow-up care via telemedicine in the year following the COVID-19 pandemic onset DESIGN: Longitudinal cohort study SETTING: Three academic adolescent medicine clinics in the United States PARTICIPANTS: AYAs using LARC INTERVENTIONS: None MAIN OUTCOME MEASURES: The main outcome measures were patient characteristics, visit information (frequency, timing, and modality), patient-reported symptoms, and outcomes for those presenting for LARC follow-up care between April 1, 2020, and March 31, 2021. Descriptive statistics were used to describe the sample. χ² tests and t tests were used to compare groups. Adjusted logistic regression models using general estimating equations were applied to assess factors associated with telemedicine visits and to examine visit outcomes.

RESULTS

Of the 319 AYAs (ages 13.6-25.7 years), 40.1% attended at least one LARC telemedicine visit. Patients attending any telemedicine encounter vs only in-person visits had similar demographic and clinical characteristics. Of the 426 follow-up visits, 270 (63.4%) were conducted in person and 156 (36.6%) were performed via telemedicine. Most visits (62.7%) occurred within 12 months of device insertion. Reports of bothersome uterine bleeding beyond patient expectations (OR = 1.26; 95% CI, 0.80-1.96), any symptom (OR = 1.40; 95% CI, 0.94-2.10), or 2 or more symptoms (OR = 1.22; 95% CI, 0.67-2.22) at follow-up was not associated, positively or negatively, with mode of follow-up. Management of bleeding (OR = 1.27; 95% CI, 0.56-2.89), management of acne (P = .46), and need for rapid follow-up (P = .33) were similar between follow-up modalities.

CONCLUSIONS

Patient demographic/clinical characteristics and visit outcomes were similar between telemedicine and in-person LARC follow-up. Telemedicine could play an important role in AYA LARC care.

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.

COVID-19 related familial economic disruptions and eating disorder patients' mental health concerns and motivation to recover

BACKGROUND

Family support has been shown to be important for adolescents and young adults (AYA) in eating disorder (ED) treatment. Many families were impacted by the pandemic, potentially altering their ability to support individuals in ED treatment. This study examined the association of COVID-19 related familial economic change with self-reported mental health (MH) and ED concerns in AYA seeking treatment for ED.

METHODS

AYA patients with EDs aged 10-27 years enrolled in the Registry of Eating Disorders and their Co-morbidities OVER time in Youth (RECOVERY) completed an additional COVID-19-specific survey (n = 89) that assessed their perception of the effects of the pandemic on their lives and their ED. Participants self-reported on familial economic disruptions, measured through a composite score of four markers: (1) family member's work hours cut, (2) family member was required to stop working, (3) family member lost job permanently, and (4) family lost health insurance/benefits. In bivariate analyses, we examined the association between self-reporting any familial economic disruption and self-reported changes in intrusive ED thoughts, feelings of anxiety, feelings of depression, feelings of isolation, and motivation to recover from their ED. Logistic regression models were used to examine the association between familial economic disruptions on self-reported changes in ED/MH affect and motivation to recover adjusting for age and ED diagnosis.

RESULTS

Forty-six percent of participants self-reported that the pandemic had resulted in at least one economic familial disruption. Of patients reporting any familial economic disruption, 29% reported decreased motivation for ED recovery, and over 75% reported worsening feelings of depression, anxiety, isolation, and/or intrusive eating disorder thoughts. Reporting any COVID-19 familial economic disruption was marginally associated with feelings of isolation (p = 0.05). Though the findings were only marginally significant, the odds of reporting worsening feelings of depression, anxiety, intrusive ED thoughts or motivation to recover were nearly twice in those who reported a COVID-19-related familial economic disruption compared to those who did not report such a disruption.

CONCLUSIONS

Family-related economic disruptions are associated with ED/MH-related concerns and motivation to recover from an ED during the COVID-19 pandemic in AYA patients.

Association of the COVID-19 Pandemic With Adolescent and Young Adult Eating Disorder Care Volume

IMPORTANCE

The COVID-19 pandemic has affected youth mental health. Increases in site-specific eating disorder (ED) care have been documented; however, multisite studies demonstrating national trends are lacking.

OBJECTIVE

To compare the number of adolescent/young adult patients seeking inpatient and outpatient ED care before and after onset of the COVID-19 pandemic.

DESIGN, SETTING, AND PARTICIPANTS

Using an observational case series design, changes in volume in inpatient and outpatient ED-related care across 15 member sites (14 geographically diverse hospital-based adolescent medicine programs and 1 nonhospital-based ED program) of the US National Eating Disorder Quality Improvement Collaborative was examined. Sites reported monthly volumes of patients seeking inpatient and outpatient ED care between January 2018 and December 2021. Patient volumes pre- and postpandemic onset were compared separately for inpatient and outpatient settings. Demographic data such as race and ethnicity were not collected because this study used monthly summary data.

EXPOSURES

Onset of the COVID-19 pandemic.

MAIN OUTCOMES AND MEASURES

Monthly number of patients seeking inpatient/outpatient ED-related care.

RESULTS

Aggregate total inpatient ED admissions were 81 in January 2018 and 109 in February 2020. Aggregate total new outpatient assessments were 195 in January 2018 and 254 in February 2020. Before the COVID-19 pandemic, the relative number of pooled inpatient ED admissions were increasing over time by 0.7% per month (95% CI, 0.2%-1.3%). After onset of the pandemic, there was a significant increase in admissions over time of 7.2% per month (95% CI, 4.8%-9.7%) through April 2021, then a decrease of 3.6% per month (95% CI, -6.0% to -1.1%) through December 2021. Prepandemic, pooled data showed relative outpatient ED assessment volume was stable over time, with an immediate 39.7% decline (95% CI, -50.4% to -26.7%) in April 2020. Subsequently, new assessments increased by 8.1% (95% CI, 5.3%-11.1%) per month through April 2021, then decreased by 1.5% per month (95% CI, -3.6% to 0.7%) through December 2021. The nonhospital-based ED program did not demonstrate a significant increase in the absolute number of admissions after onset of the pandemic but did see a significant increase of 8.2 (95% CI, 6.2-10.2) additional inquiries for care per month in the first year after onset of the pandemic.

CONCLUSIONS AND RELEVANCE

In this study, there was a significant COVID-19 pandemic-related increase in both inpatient and outpatient volume of patients with EDs across sites, particularly in the first year of the pandemic. Given inadequate ED care availability prior to the pandemic, the increased postpandemic demand will likely outstrip available resources. Results highlight the need to address ED workforce and program capacity issues as well as improve ED prevention strategies.

Unraveling the meaning of weight misperception in a sample of college students: Unaware or body satisfied?

Weight misperception has been seen as a threat to public health. We aimed to understand the meaning of weight misperception by examining associations of weight perception with body satisfaction and body awareness along with healthy ideals and culturally normative body ideals. Undergraduates with higher weights at a Mid-South University (n = 166) completed survey measures that included: weight status perception ("How do you think of yourself in terms of weight?"), self-reported weight and height (used to indicate awareness), current and ideal body size using Figure Rating Scales (FRS), three measures of body satisfaction (difference between current and ideal figures on FRS, Appearance Evaluation subscale of the Multidimensional Body Self-Relations Questionnaire, Body Dissatisfaction subscale of the Eating Disorder Inventory-3). Height and weight were also measured. Thirty percent (n = 49) of participants perceived themselves as 'healthy' weight and 70 % (n = 117) perceived themselves as above healthy weight. In bivariate analyses, there were no significant differences in identification of healthy or culturally normative body ideals by weight perception group. A series of logistic regression models were run to examine associations between weight perception and both BMI awareness and body satisfaction. In unadjusted and adjusted models, increased body satisfaction was associated with reduced odds of perceiving oneself above healthy weight (OR: 0.25, p < 0.001); BMI awareness was not associated with weight misperception. Findings suggest that weight misperception reflects body satisfaction, and not a lack of awareness of body weight/size, definitions of healthy bodies, or culturally normative body ideals. "Correcting" individuals who perceive their bodies as about right has the potential to cause great harm and should be eliminated as a public health goal.

A Comparison of Methods Examining Time-to-Readmission in the First Year of Life

BACKGROUND AND OBJECTIVES

Readmissions analyses typically calculate time-to-readmission relative to hospital discharge. For newborns, this definition can be challenging when comparing groups with disparate birth stays. We compare 2 approaches to calculate readmissions and examine 1 year readmissions for newborns with versus without neonatal opioid withdrawal syndrome (NOWS; mean length of stay = 17 vs 2 days).

METHODS

Using birth discharge data from the Pediatric Health Information System (PHIS), we compared crude and adjusted 1 year readmissions by NOWS diagnosis using Cox regression models predicting time-to-readmission from: (1) birth discharge; and (2) birth (day-of-life), with left truncation allowing for delayed entry into the at-risk period at birth discharge.

RESULTS

We included N = 155 885 birth discharges (n = 1467 with NOWS). At 1 year, 10% of infants with NOWS versus 6% without had been readmitted. Readmission risk was highest within 1 week since discharge or birth for newborns without NOWS, whereas those with NOWS were at higher risk later into infancy. NOWS was associated with a higher adjusted hazard of 1 year readmissions since discharge (adjusted hazard ratio [aHR]=1.58; 95% CI: 1.20-2.08) and a higher adjusted hazard of 1 year readmissions since birth (aHR = 1.56; 95% CI: 1.21-2.03). Estimates vary by choice of index date, particularly at early time-points, converging later into infancy.

CONCLUSIONS

Our findings underscore the importance of methodological decisions for newborn readmissions. Although results were similar at 1 year with nearly identical adjusted hazards, approaches differed substantially through the neonatal period.

Electronic surveillance of patient safety events using natural language processing

Objective

We describe our approach to surveillance of reportable safety events captured in hospital data including free-text clinical notes. We hypothesize that a) some patient safety events are documented only in the clinical notes and not in any other accessible source; and b) large-scale abstraction of event data from clinical notes is feasible.

Materials and Methods

We use regular expressions to generate a training data set for a machine learning model and apply this model to the full set of clinical notes and conduct further review to identify safety events of interest. We demonstrate this approach on peripheral intravenous (PIV) infiltrations and extravasations (PIVIEs).

Results

During Phase 1, we collected 21,362 clinical notes, of which 2342 were reviewed. We identified 125 PIV events, of which 44 cases (35%) were not captured by other patient safety systems. During Phase 2, we collected 60,735 clinical notes and identified 440 infiltrate events. Our classifier demonstrated accuracy above 90%.

Conclusion

Our method to identify safety events from the free text of clinical documentation offers a feasible and scalable approach to enhance existing patient safety systems. Expert reviewers, using a machine learning model, can conduct routine surveillance of patient safety events.

A Methodology to Create Mother-Baby Dyads Using Data From the Pediatric Health Information System

BACKGROUND AND OBJECTIVES

Linking newborn birth records with maternal delivery data is invaluable in perinatal research, though linkage is often challenging or impossible in the context of administrative data. Using data from the Pediatric Health Information System (PHIS), we describe a novel methodology to link maternal delivery data with newborn birth hospitalization records to form mother-baby dyads.

METHODS

We extracted singleton birth discharges and maternal delivery discharges between 2016 and 2020 from hospitals submitting large volumes of maternal delivery discharges and newborn deliveries into PHIS. Birth discharges at these PHIS hospitals included routine births and those requiring specialty care. Newborn discharges were matched to maternal discharges within hospital by date of birth, mode of delivery, and ZIP code.

RESULTS

We identified a matching maternal discharge for 92.1% of newborn discharges (n = 84 593/91 809). Within-hospital match rates ranged from 87.4% to 93.9%. Within the matched cohort, most newborns were normal birth weight (91.2%) and term (61.2%) or early term (27.4%). A total of 88.8% of newborns had birth stays less than 5 days and 14.2% were admitted to the NICU.

CONCLUSIONS

We demonstrate the feasibility of deterministically linking maternal deliveries to newborn discharges forming mother-baby dyads with a high degree of success using data from PHIS. The matched cohort may be used to study a variety of neonatal conditions that are likely to be affected by maternal demographic or clinical factors at delivery. Validation of this methodology is an important next step and area of future work.

Phenotypes of disease severity in a cohort of hospitalized COVID-19 patients: Results from the IMPACC study

BACKGROUND

Better understanding of the association between characteristics of patients hospitalized with coronavirus disease 2019 (COVID-19) and outcome is needed to further improve upon patient management.

METHODS

Immunophenotyping Assessment in a COVID-19 Cohort (IMPACC) is a prospective, observational study of 1164 patients from 20 hospitals across the United States. Disease severity was assessed using a 7-point ordinal scale based on degree of respiratory illness. Patients were prospectively surveyed for 1 year after discharge for post-acute sequalae of COVID-19 (PASC) through quarterly surveys. Demographics, comorbidities, radiographic findings, clinical laboratory values, SARS-CoV-2 PCR and serology were captured over a 28-day period. Multivariable logistic regression was performed.

FINDINGS

The median age was 59 years (interquartile range [IQR] 20); 711 (61%) were men; overall mortality was 14%, and 228 (20%) required invasive mechanical ventilation. Unsupervised clustering of ordinal score over time revealed distinct disease course trajectories. Risk factors associated with prolonged hospitalization or death by day 28 included age ≥ 65 years (odds ratio [OR], 2.01; 95% CI 1.28-3.17), Hispanic ethnicity (OR, 1.71; 95% CI 1.13-2.57), elevated baseline creatinine (OR 2.80; 95% CI 1.63- 4.80) or troponin (OR 1.89; 95% 1.03-3.47), baseline lymphopenia (OR 2.19; 95% CI 1.61-2.97), presence of infiltrate by chest imaging (OR 3.16; 95% CI 1.96-5.10), and high SARS-CoV2 viral load (OR 1.53; 95% CI 1.17-2.00). Fatal cases had the lowest ratio of SARS-CoV-2 antibody to viral load levels compared to other trajectories over time (p=0.001). 589 survivors (51%) completed at least one survey at follow-up with 305 (52%) having at least one symptom consistent with PASC, most commonly dyspnea (56% among symptomatic patients). Female sex was the only associated risk factor for PASC.

INTERPRETATION

Integration of PCR cycle threshold, and antibody values with demographics, comorbidities, and laboratory/radiographic findings identified risk factors for 28-day outcome severity, though only female sex was associated with PASC. Longitudinal clinical phenotyping offers important insights, and provides a framework for immunophenotyping for acute and long COVID-19.

Effect of clinician information sessions on diagnostic testing for Chagas disease

Background

Chagas disease is a potentially life-threatening neglected disease of poverty that is endemic in continental Latin America. Caused by Trypanosoma cruzi (T. cruzi), it is one of six parasitic diseases in the United States targeted by the Centers for Disease Control as a public health problem in need of action. An estimated 300,000 people are infected with T. cruzi in the United States (US). Although its morbidity, mortality and economic burden are high, awareness of Chagas disease is lacking among many healthcare providers in the US. The purpose of this analysis is to determine if the number of diagnostic tests performed at a community health center serving an at-risk population for Chagas disease increased after information sessions. A secondary aim was to determine if there was a difference by provider type, i.e., nurse practitioner vs. physician, or by specialty in the number of patients screened.

Methodology/Principal findings

We conducted a retrospective data analysis of the number of Chagas serology tests performed at a community health center before and after information sessions for clinicians. A time series analysis was conducted focusing on the Adult and Family Medicine Departments at East Boston Neighborhood Health Center (EBNHC). Across all departments there were 1,957 T. cruzi tests performed before the sessions vs. 2,623 after the sessions. Interrupted time series analysis across departments indicated that testing volume was stable over time prior to the sessions (pre-period slope = +4.1 per month; p = 0.12), followed by an immediate shift after the session (+51.6; p = 0.03), while testing volume remained stable over time after the session (post-period slope = -6.0 per month; p = 0.11).

Conclusion/Significance

In this study, Chagas testing increased after information sessions. Clinicians who began testing their patients for Chagas disease after learning of the importance of this intervention added an extra, potentially time-consuming task to their already busy workdays without external incentives or recognition.

Chagas disease is a potentially fatal neglected disease of poverty. It is endemic in continental Latin America with an estimated 300,000 cases in the United States, primarily among low-income people who have immigrated to the US from Latin America. Few Chagas screening programs have been established in the US. Existing recommendations for Chagas disease testing and treatment are rarely followed for many reasons including a paucity of knowledge among providers. We aimed to determine if the number of Chagas tests performed increased after information sessions at a community health center. A secondary aim was to determine if there was a difference in number of tests performed by provider type. We found that the number of T. cruzi serologies performed in the ten months after information sessions increased significantly over that in the ten preceding months. Chagas testing increased across departments, though Chagas diagnostics were an extra and unmitigated time burden on clinicians. Increasing provider knowledge is a major step to increase diagnosis and treatment of this neglected disease, when clinicians are motivated by their inherent prosocial preferences including altruism i.e., by the positive impact of their work on patients’ lives.

Relationships Between Pediatric Safety Indicators Across a National Sample of Pediatric Hospitals: Dispelling the Myth of the "Safest" Hospital

OBJECTIVE

There are many measures of healthcare quality, but no obvious summary measures to simplify ranking of hospital performance. With public reporting and accountability for hospital performance, the validity of composite measures for performance rankings has increased importance. This study aimed to explore the covariance of pediatric hospital quality indicators and evaluate the use of a single composite score.

METHODS

We performed an observational study of pediatric hospital performance across 13 safety indicators extracted from the Pediatric Health Information System, a comparative database of children's hospitals in the United States. We included patients discharged from 36 hospitals from January 1, 2016, to December 31, 2019. Using principal components analysis, we investigate relationships among patient safety measures from the Agency for Healthcare Research and Quality pediatric quality indicators and Center for Medicare and Medicaid Services hospital-acquired conditions. We compare and summarize rankings based on individual safety indicators and calculate alternative composite scores.

RESULTS

We identified 5 orthogonal variance components accounting for 68% of variation in pediatric hospital quality indicators. Rankings demonstrated greater within-hospital variation compared with between-hospital variation. We observed discordant rankings across commonly used summary measures and conclude that these pediatric safety measures demonstrate at least 2 underlying variance components.

CONCLUSIONS

This study demonstrates the multifactorial nature of patient safety. This implies no unique ordering of hospitals based on these measures, and thus, no pediatric hospital can claim to be "the safest." This raises further questions about appropriate methods to rank hospitals by safety.

Adolescent individual, school, and neighborhood influences on young adult hypertension risk

BACKGROUND

Geographic and contextual socioeconomic risk factors in adolescence may be more strongly associated with young adult hypertension than individual-level risk factors. This study examines the association between individual, neighborhood, and school-level influences during adolescence on young adult blood pressure.

METHODS

Data were analyzed from the National Longitudinal Study of Adolescent to Adult Health (1994-1995 aged 11-18 and 2007-2008 aged 24-32). We categorized hypertension as systolic blood pressure ≥140 mm Hg and/or diastolic blood pressure ≥90 mm Hg. Secondary outcomes included continuous systolic and diastolic blood pressure. We fit a series of cross-classified multilevel models to estimate the associations between young adulthood hypertension with individual-level, school-level, and neighborhood-level factors during adolescence (i.e., fixed effects) and variance attributable to each level (i.e., random effects). Models were fit using Bayesian estimation procedures. For linear models, intra-class correlations (ICC) are reported for random effects.

RESULTS

The final sample included 13,911 participants in 128 schools and 1,917 neighborhoods. Approximately 51% (7,111) young adults were hypertensive. Individual-level characteristics-particularly older ages, Non-Hispanic Black race, Asian race, male sex, BMI, and current smoking-were associated with increased hypertension. Non-Hispanic Black (OR = 1.21; 95% CI: 1.03-1.42) and Asian (OR = 1.28; 95% CI: 1.02-1.62) students had higher odds of hypertension compared to non-Hispanic White students. At the school level, hypertension was associated with the percentage of non-Hispanic White students (OR for 10% higher = 1.06; 95% CI: 1.01-1.09). Adjusting for individual, school, and neighborhood predictors attenuated the ICC for both the school (from 1.4 null to 0.9 fully-adjusted) and neighborhood (from 0.4 to 0.3).

CONCLUSION

We find that adolescents' schools and individual-level factors influence young adult hypertension, more than neighborhoods. Unequal conditions in school environments for adolescents may increase the risk of hypertension later in life. Our findings merit further research to better understand the mechanisms through which adolescents' school environments contribute to adult hypertension and disparities in hypertension outcomes later in life.

Adolescent/Young Adult Long-Acting Reversible Contraception: Experience from a Multisite Adolescent Medicine Collaborative

OBJECTIVE

To report on long-acting reversible contraception (LARC) experience and continuation rates in the Adolescent Medicine LARC Collaborative.

STUDY DESIGN

LARC insertion data (682 implants and 681 intrauterine devices [IUDs]) were prospectively collected from January 1, 2017, through December 31, 2019, across 3 Adolescent Medicine practices. Follow-up data through December 31, 2020, were included to ensure at least 1 year of follow-up of this cohort. Continuation rates were calculated at 1, 2, and 3 years, overall and by Adolescent Medicine site, as were descriptive statistics for LARC procedural complications and patient experience.

RESULTS

Implant and IUD insertion complications were uncommon and largely self-limited, with no IUD-related uterine perforations. Uterine bleeding was the most frequently reported concern at follow-up (35% implant, 25% IUD), and a common reason for early device removal (45% of implant removals, 32% of IUD removals). IUD malposition or expulsion occurred following 6% of all insertions. The pooled implant continuation rate at 1 year was 87% (range, 86%-91% across sites; P = .63), 66% at 2 years (range, 62%-84%; P = .01), and 42% at 3 years (range, 36%-60%; P = .004). The pooled IUD continuation rate at 1 year was 88% (range, 87%-90% across sites; P = .82), 77% at 2 years (range, 76%-78%; P = .94), and 60% at 3 years (range, 57%-62%; P = .88).

CONCLUSIONS

LARC is successfully provided in Adolescent Medicine clinical settings, with continuation rates analogous to those of well-resourced clinical trials. Uterine bleeding after LARC insertion is common, making counselling imperative. Future analyses will assess whether the medical management of LARC-related nuisance bleeding improves continuation rates in our Adolescent Medicine patient population.

Frequency and Nature of Communication and Handoff Failures in Medical Malpractice Claims

BACKGROUND

The Joint Commission has identified miscommunication as a leading cause of sentinel events, the most serious adverse events, but it is unclear what role miscommunications play in malpractice claims. We sought to determine the proportion of medical malpractice claims involving communication failure and describe their nature, including providers involved, locations, miscommunications types, costs, and the potential for handoff tools to avert risk and associated costs.

METHODS

We retrospectively reviewed a random sample of malpractice claims from 2001 to 2011, collected in CRICO Strategies' Comparative Benchmarking System, a national claims database. Two researchers reviewed cases to determine if a claim involved communication failure, its type, and potential preventability using a communication tool. Interrater reliability was assessed by dual review of 50 cases (81% agreement, κ = 0.62 for evidence of miscommunication). Claimant demographics, case characteristics, and financial data were analyzed.

RESULTS

Communication failures were identified in 49% of claims. Claims with communication failures were significantly less likely to be dropped, denied, or dismissed than claims without (54% versus 67%, P = 0.015). Fifty-three percent of claims with communication failures involved provider-patient miscommunication, and 47% involved provider-provider miscommunication. The information types most frequently miscommunicated were contingency plans, diagnosis, and illness severity. Forty percent of communication failures involved a failed handoff; the majority could potentially have been averted by using a handoff tool (77%). Mean total costs for cases involving communication failures were higher ($237,600 versus $154,100, P = 0.005).

CONCLUSIONS

Communication failures are a significant contributing cause of malpractice claims and impose a substantial financial burden on the healthcare system. Interventions to improve transmission of critical patient information have the potential to substantially reduce malpractice expenditures.

Can digital engagement improve outcomes for total joint replacements?

Background

Patient activation and engagement can improve outcomes of medical and surgical care by increasing involvement of patients in their care plan. We designed a digital engagement tool to improve surgical cancellation and post-surgical outcomes for adult patients undergoing total joint replacements by providing patient education materials via email or text, in small increments throughout the perioperative period.

Methods

We assessed the tool's impact using a quasi-experimental design comparing patients scheduled for surgery January–June 2017 (pre-intervention) versus January–June 2018 (post-intervention). Post-intervention patients with digital contact information in the medical record were automatically enrolled. We extracted de-identified administrative data for all patients during both time periods and utilized an intent-to-treat approach including all post-intervention patients regardless of enrollment. Surgical cancellation and post-surgical outcomes (length of stay, discharge to home and revisits and readmissions) were compared between periods using adjusted regression models. We also examined associations between measures of engagement with the intervention and outcomes.

Results

A total of 2027 joint replacement patients were included (720 hip replacements; 1307 knee replacements). Adjusting for gender, age and insurance type, both hip and knee patients in the post-intervention group were more likely to have a cancelled surgery, but cancellations were less likely to be on the day of surgery compared to pre-intervention patients. Post-intervention patients were also less likely to have length of stay >2 days. Forty- three per cent of hip and 47% of knee patients in the post-period received the intervention and most were highly engaged. Higher engagement was associated with lower odds of surgical cancellation, shorter stays and higher odds of discharge home.

Conclusion

Findings suggest that utilization of a digital patient engagement tool translates into improved hospital efficiency and patient outcomes, particularly for those highly engaged.

The Impact of the COVID-19 Pandemic on the Number of Adolescents/Young Adults Seeking Eating Disorder-Related Care

PURPOSE

The COVID-19 pandemic has led to the development and worsening of eating disorder (ED) symptoms in adolescents and young adults. In order to examine COVID-19-related trends in ED care-seeking at our institution.

METHODS

We used interrupted time series regression to examine pre- and postpandemic monthly summary data of the following: (1) ED-related inpatient admissions for medical stabilization; (2) ED-related hospital bed-days; (3) completed outpatient ED assessments; and (4) ED outpatient care-related inquiries at a children's hospital in Boston, MA.

RESULTS

Inpatient admissions, hospital bed-days, and outpatient care-related inquiries increased on average over time postpandemic compared to stable volume over time prepandemic (p < .01). Outpatient assessments decreased precipitously initially following COVID-19-related limitations, and rose quickly back to baseline.

CONCLUSION

These results indicate increased need for ED-related care during the pandemic. Bolstering resources to meet the needs of these vulnerable patients is critical as the effects of the pandemic continue to be felt.

Pediatric Hospital Readmissions for Infants With Neonatal Opioid Withdrawal Syndrome, 2016-2019

BACKGROUND AND OBJECTIVES

Neonatal opioid withdrawal syndrome (NOWS) is associated with long and costly birth hospitalization and increased readmission risk. Our objective was to examine readmissions in the first year of life for infants diagnosed with NOWS compared with infants without NOWS, adjusting for sociodemographic and clinical factors, and to describe use during readmissions in this population.

METHODS

Using data from the Pediatric Health Information System, we identified singleton term infants with NOWS and without NOWS or other major condition (by diagnosis codes and All Patient Refined Diagnosis Related Groups coding, respectively) discharged from 2016 to 2019. We predicted time to first readmission within the first year of life using Cox regression analysis. Predictors included NOWS diagnosis, sociodemographic factors, birth NICU use, and birth weight.

RESULTS

We included 155 885 birth discharges from 17 hospitals (n = 1467 NOWS) with 10 087 readmissions. Unadjusted 1-year readmission rates were 9.9% among NOWS infants versus 6.2% among those without NOWS. The adjusted hazard ratio for readmission within the first year was 1.76 (95% confidence interval: 1.40-2.22) for infants with NOWS versus those without. Readmissions for infants with NOWS were longer and costlier and more likely to require intensive care and mechanical ventilation. Readmissions among infants without NOWS were most commonly for jaundice and respiratory and other infections, whereas respiratory infections were the leading cause of readmissions among NOWS infants.

CONCLUSIONS

Infants with a NOWS diagnosis were more likely to be readmitted within the first year of life. In future work, researchers should explore potential interventions to prevent readmissions and provide resources to families affected by opioid dependence.

Variation in Hospital Performance Measures from the Turkey Ministry of Health

BACKGROUND

The Turkish healthcare system has seen broad population-based improvements in expanded health insurance coverage and access to healthcare services. Hospital performance in this national system is understudied. We aimed to identify trends in hospital performance over time following implementation of the Health Transformation Program and describe how regional outcomes correlate with regional vital statistics.

METHODS

We conducted a retrospective cohort study of 674 public hospitals in Turkey using baseline data from 2013 and follow-up data from 2014-15 collected by the Turkish Statistical Institution (TSI) and the Public Hospital Agency (PHA). We report demographic and socioeconomic data across 12 geographic regions and analyze 29 hospital-level performance measures across four domains: (1) health services; (2) administrative services; (3) financial services; and (4) quality measures. We examine temporal variation, and study correlation between performance measures and regional vital statistics. We fit mixed-effects linear regression models to estimate linear trend over time accounting for within-hospital residual correlation. We prepared our manuscript in accordance with guidelines set by the STROBE statement for cohort studies.

RESULTS

During the three years of study period, 21 of 29 measures improved, and 8 measures worsened. All but 3 measures demonstrated significant differences across regions of the country. Several measures, including inpatient efficiency, patient satisfaction, and audit score, are associated with regional infant mortality and life expectancy.

CONCLUSIONS

Evidence for temporal improvement in hospital-level performance may suggest some positive changes within the Turkish national healthcare system. Correlation of some measures with regional level health outcomes suggests a quality measurement strategy to monitor performance changes in the future. Although hospital-level functions have improved performance, the results of our study may help achieve further improvement for the health of the country's citizens.

COVID-19 and eating disorder and mental health concerns in patients with eating disorders

BACKGROUND

The Coronavirus (COVID-19) pandemic dramatically transformed daily life for adolescents and young adults, altering social and physical environments. Previous research has shown such shifts in daily life to be especially challenging for people living with eating disorders (ED). However, the extent of this environmental change on ED symptoms and mental health (MH) has been relatively unexplored in patients with EDs. This study examines how young people with EDs feel the COVID-19 pandemic has affected their living environments as well as their ED and MH symptoms and motivation for ED recovery.

METHODS

Participants were enrollees in the Registry of Eating Disorders and their Co-morbidities OVER time in Youth (RECOVERY) who responded to an additional survey (n = 89) in July 2020 to assess their perceptions of the impact of the COVID-19 pandemic. Participants reported on concerns of their ED worsening due to increased time living in a "triggering environment" due to the pandemic as well as perceived COVID-related changes in intrusive ED thoughts, depression, anxiety, isolation, and motivation to recover. Logistic regression models, adjusted for age and ED diagnosis, examined the association of triggering environment with ED and MH symptoms.

RESULTS

The majority of respondents reported concern for worsening of their ED due to a "triggering environment" (63%). Most reported an increase in ED thoughts (74%), feelings of anxiety (77%), depression (73%), and isolation (80%) they perceived to be related to the pandemic. Nearly one-third reported decrease in motivation to recover (29%) they perceived to be related to the pandemic. After adjusting for age and ED diagnosis, participants who reported concern for worsening of their ED due to a triggering environment had nearly 18 times the odds of decreased motivation to recover (OR 18.1; 95% CI 3.37-97.4, p = 0.003) and nearly 24 times the odds of increased ED thoughts (OR 23.8; 95% CI 4.31-131.6, p < 0.001) compared to those who did not report concern for worsening of their ED due to a triggering environment.

CONCLUSIONS

Our findings demonstrate the perceived negative impact the COVID-19 pandemic has had on the self-reported ED and MH symptoms in patients with EDs, particularly in those who report concern for a negative environmental change. These results underscore the need for heightened monitoring of patients with EDs during the pandemic.

Access to care and worsening eating disorder symptomatology in youth during the COVID-19 pandemic

BACKGROUND

Shelter-in-place orders and social distancing guidelines, in response to the COVID-19 pandemic, have limited traditional face-to-face interactions and led to many clinical providers transitioning to the use of videoconferencing platforms. The present study aims to assess how the COVID-19 pandemic has impacted adolescents'/young adults' (AYA) eating disorder (ED)-related care, and how access to, changes in, perceived disruptions to, and quality of care are associated with ED thoughts and behaviors.

METHODS

AYA enrolled in the RECOVERY study, a pre-existing web-based longitudinal study, and completed a COVID-19-specific survey (n = 89). We examined bivariate associations of four markers of care: i) access to care, ii) changes in care, iii) perceived disruption to care, and iv) quality of care. Using multiple logistic regression, we examined the associations of pandemic-related markers of care with changes in ED thoughts and behaviors. We excluded those not engaged in treatment pre-pandemic (n = 16).

RESULTS

In the remaining 73 participants, reported access to care was high, with 92% of respondents continuing care with at least one ED provider during the pandemic; however, 47% stopped some treatment during the pandemic. Nearly one-third (32%) perceived a disruption in treatment. Quality of care remained high with 67% reporting care to be better than or as good as pre-pandemic. Respondents acknowledged heightened symptomatology: 81% reported increased ED thoughts and 81% reported increased ED behaviors due to COVID-19-related factors. However, none of the markers of care described were significantly associated with ED thoughts or behaviors in regression analyses adjusting for demographic variables and baseline characteristics, except our quality of care measure which was approaching significance (p = 0.07).

CONCLUSIONS

Our findings show the majority of AYA who had care prior to the pandemic continued receiving some element of their multi-disciplinary ED treatment and perceived their care as high quality. None of the markers of care described were statistically associated with increased ED thoughts and behaviors.

The Association of Malnutrition, illness duration, and pre-morbid weight status with anxiety and depression symptoms in adolescents and young adults with restrictive eating disorders: a cross-sectional study

BACKGROUND

Restrictive eating disorders (EDs) are often comorbid with anxiety and depression symptoms, placing patients at risk for more severe disease, worse treatment outcomes, and higher rates of mortality. To identify risks for developing such co-morbidities, we assessed the association of malnutrition, ED illness duration, and pre-morbid weight status with symptoms of anxiety and depression in adolescents/young adults (AYAs) with EDs.

METHODS

145 participants with restrictive EDs (anorexia nervosa [AN], other specified feeding and eating disorders [OSFED], avoidant restrictive food intake disorder [ARFID]) were included from the RECOVERY study, a longitudinal web-based registry of AYAs with EDs. We measured malnutrition as percent of expected body mass index (%eBMI), based on participants' pre-morbid growth trajectory. Outcomes were anxiety and depression scores from the Generalized Anxiety Disorder 7-item (GAD-7) and Center for Epidemiologic Studies Depression (CES-D) scales. We used multiple linear regression to examine the association of malnutrition, ED duration, and pre-morbid weight status with symptoms of anxiety and depression.

RESULTS

Mean (SD) age was 16.4(3.0) years; 87% were female; 89% white; 85% had AN, 6% OSFED, 10% ARFID. Of these, 2/3 had ED symptoms ≥1 year, 1/3 had previous higher level of ED care (HLOC), and half were taking psychiatric medications. Mean %eBMI was 90% (range 57-112%). Mean GAD-7 was 9.4(5.9) and CES-D was 24(13.8), indicating most participants had clinically significant anxiety and/or depression. Degree of malnutrition was not significantly associated with anxiety or depression adjusting for age, sex, sexual orientation, ED diagnosis, and use of psychiatric medication. Those with longer duration of ED symptoms had higher depression scores after adjusting for malnutrition, HLOC, length of ED symptoms, and time in our care (p = 0.038). Patients with pre-morbid BMIs ≥75th percentile had lower depression scores than those with pre-morbid BMIs <75th percentile (p = 0.014).

CONCLUSIONS

We find high degree of clinically relevant anxiety and depression symptoms in a population of AYAs with EDs. Our findings suggest that factors beyond malnutrition play a role in the co-morbid mood and anxiety disorders in this population. Overall, rapid ED diagnosis and comprehensive treatment for patients with EDs across the weight spectrum-and especially those with psychiatric co-morbidities-will likely aid in recovery.

Perceived barriers to Chagas disease screening among a diverse group of prenatal care providers

BACKGROUND

Chagas disease is a vector borne infection of poverty endemic to Latin America which affects an estimated 40,000 women of child-bearing age in the United States (US). In the US Chagas disease is concentrated among individuals who have lived in endemic areas. Prenatal diagnosis and treatment are needed to prevent congenital transmission. The objective of this study was to assess perceived barriers to Chagas disease screening among prenatal care providers in Obstetrics/Gynecology and Family Medicine Departments of a tertiary care safety-net hospital caring for a significant at-risk population.

METHODOLOGY/PRINCIPAL FINDINGS

An anonymous survey was distributed to 178 Obstetrics/Gynecology and Family Medicine practitioners. Of the 66 respondents, 39% thought Chagas screening was very important, and 48% somewhat important as a public health initiative. One third judged screening patients during clinic visits as very important. Most respondents (64%) reported being familiar with Chagas disease. However, only 32% knew how to order a test and only 22% reported knowing what to do if a test was positive.

CONCLUSIONS/SIGNIFICANCE

These findings will be incorporated into measures to facilitate full implementation of Chagas screening, and can inform initiatives at other centers who wish to address this deeply neglected infection among their patient families. Greater integration of information on Chagas disease screening and treatment in medical and nursing education curricula can contribute to addressing this disease with the focus that its potentially fatal sequelae merit.

Disentangling individual, school, and neighborhood effects on screen time among adolescents and young adults in the United States

OBJECTIVES

To examine the association between individual, neighborhood, and school-level influences on individual screen time among adolescents and young adults (AYAs) in the National Longitudinal Study of Adolescent to Adult Health.

METHODS

We classified screen time continuously as self-reported total hours per week of television, videos, and video/computer games at baseline and categorical as extended screen time (≥14 h per week). We fit cross-classified multilevel models (CCMM) to examine to examine the individual-, school- and neighborhood-level demographic and socioeconomic factors associated with screen time. Models were fit using MLwiN with Bayesian estimation procedures.

RESULTS

AYAs reported an average of 22.8 (SD = 19.4) and 21.9 (SD = 20.3) hours of screen time, respectively. At the individual level, younger age, male sex, Black/multiracial race, receipt of public assistance, and lower parental education were associated with higher screen time. At the school level, being out of session (i.e., school and national holidays including summer), having a higher proportion of non-White students, and having a lower proportion of parents with a college education were associated with higher individual screen time.

CONCLUSIONS

We found that individual-level factors most influence youth screen time, with smaller contributions from school factors.

Limiting Vancomycin Exposure in Pediatric Oncology Patients With Febrile Neutropenia May Be Associated With Decreased Vancomycin-Resistant Enterococcus Incidence

BACKGROUND

Limited data exists regarding the effects of empiric antibiotic use in pediatric oncology patients with febrile neutropenia (FN) on the development of antibiotic resistance. We evaluated the impact of a change in our empiric FN guideline limiting vancomycin exposure on the development of vancomycin-resistant Enterococcus in pediatric oncology patients.

METHODS

Retrospective, quasi-experimental, single-center study using interrupted timeseries analysis in oncology patients aged ≤18 years with at least 1 admission for FN between 2009 and 2015. Risk strata incorporated diagnosis, chemotherapy phase, Down syndrome, septic shock, and typhlitis. Microbiologic data and inpatient antibiotic use were obtained by chart review. Segmented Poisson regression was used to compare VRE incidence and antibiotic days of therapy (DOT) before and after the intervention.

RESULTS

We identified 285 patients with 697 FN episodes pre-intervention and 309 patients with 691 FN episodes postintervention. The proportion of high-risk episodes was similar in both periods (49% vs 48%). Empiric vancomycin DOT/1000 FN days decreased from 315 pre-intervention to 164 post-intervention (P < .01) in high-risk episodes and from 199 to 115 in standard risk episodes (P < .01). Incidence of VRE/1000 patient-days decreased significantly from 2.53 pre-intervention to 0.90 post-intervention (incidence rate ratio, 0.14; 95% confidence interval, 0.04-0.47; P = .002).

CONCLUSIONS

A FN guideline limiting empiric vancomycin exposure was associated with a decreased incidence of VRE among pediatric oncology patients. Antimicrobial stewardship interventions are feasible in immunocompromised patients and can impact antibiotic resistance.

Does an uneven sample size distribution across settings matter in cross-classified multilevel modeling? Results of a simulation study

BACKGROUND

Recent advances in multilevel modeling allow for modeling non-hierarchical levels (e.g., youth in non-nested schools and neighborhoods) using cross-classified multilevel models (CCMM). Current practice is to cluster samples from one context (e.g., schools) and utilize the observations however they are distributed from the second context (e.g., neighborhoods). However, it is unknown whether an uneven distribution of sample size across these contexts leads to incorrect estimates of random effects in CCMMs.

METHODS

Using the school and neighborhood data structure in Add Health, we examined the effect of neighborhood sample size imbalance on the estimation of variance parameters in models predicting BMI. We differentially assigned students from a given school to neighborhoods within that school's catchment area using three scenarios of (im)balance. 1000 random datasets were simulated for each of five combinations of school- and neighborhood-level variance and imbalance scenarios, for a total of 15,000 simulated data sets. For each simulation, we calculated 95% CIs for the variance parameters to determine whether the true simulated variance fell within the interval.

RESULTS

Across all simulations, the "true" school and neighborhood variance parameters were estimated 93-96% of the time. Only 5% of models failed to capture neighborhood variance; 6% failed to capture school variance.

CONCLUSIONS

These results suggest that there is no systematic bias in the ability of CCMM to capture the true variance parameters regardless of the distribution of students across neighborhoods. Ongoing efforts to use CCMM are warranted and can proceed without concern for the sample imbalance across contexts.

BMI Trajectories from Birth to Young Adulthood

OBJECTIVE

This study aimed to compare BMI trajectories from childhood to early adulthood in those with overweight and/or obesity versus severe obesity.

METHODS

Longitudinal BMI values (2,542 measurements) were calculated from measured heights and weights for 103 children, adolescents, or young adults with overweight, obesity, or severe obesity. Segmented regression with splines was used to model BMI trajectories.

RESULTS

Sixty-nine participants were classified as ever having severe obesity versus 34 who never had severe obesity. Trajectories and slopes did not differ by sex or race/ethnicity. Compared with those who never had severe obesity, BMI was higher in the group with severe obesity at all ages, and BMI slope was higher for those with severe obesity at age 14 (P = 0.002), with peak slope occurring later (18 years vs. 16 years) and higher (4.5 ± 0.5 kg/m² /y vs. 2.9 ± 0.5 kg/m² /y; P < 0.02). In the group without severe obesity, BMI fell below zero by the mid-20s (-0.3 ± 0.6 kg/m² /y); in those with severe obesity, BMI slope never reached zero (0.9 ± 0.5 kg/m² /y).

CONCLUSIONS

Youth with severe obesity, compared with their peers without, started with higher BMIs, had more rapid rates of BMI increase beginning at age 14, as well as a higher peak and longer period of increase, and never achieved weight stabilization.

Hospital Variation in Neonatal Abstinence Syndrome Incidence, Treatment Modalities, Resource Use, and Costs Across Pediatric Hospitals in the United States, 2013 to 2016

BACKGROUND

The national incidence of neonatal abstinence syndrome (NAS) has increased with the opioid epidemic in the United States. The impact of pharmacologic treatment on hospital use is not well established. We examined the recent population of neonates with NAS admitted to pediatric hospitals, hospital variation in pharmacologic treatment, and the effect of treatment on resource use during neonatal hospitalization, including length of stay (LOS), readmission, and cost-of-living adjusted hospital costs.

METHODS

We included inpatients discharged between January 2013 and March 2016 from hospitals in the Pediatric Health Information System. We compared neonates with NAS to those without on demographic, socioeconomic, clinical characteristics and hospital resource use. We also compared neonates with NAS on these characteristics by pharmacologic treatment.

RESULTS

This analysis included 136 762 neonatal encounters from 23 hospitals. Of these, 2% had a diagnosis of NAS. Compared with other neonates, neonates with NAS had a longer LOS (18.7 vs 2.9 days; P = .004). Average costs per admission were 10 times higher for neonates with NAS ($37 584 vs $3536; P = .003). Of neonates with NAS, 70% were treated pharmacologically with wide variation in hospital rates of pharmacotherapy (range: 13%-90%). Pharmacologically-treated neonates with NAS experienced a longer LOS (22.0 vs 10.9 days; P = .004) than other neonates with NAS. Total costs for pharmacologically-treated neonates with NAS were over 2 times higher ($44 720 vs $20 708; P = .002) than neonates with NAS treated without pharmacotherapy.

CONCLUSIONS

Neonates with NAS, particularly those treated pharmacologically, have lengthier, more expensive hospital stays. Significant variation in pharmacologic treatment reflects opportunities for practice standardization and substantial reductions in resource use.

Cross-sectional and Prospective Examination of Weight Misperception and Depressive Symptoms Among Youth with Overweight and Obesity

This study aims to determine the association between weight misperception (considering oneself average or underweight) and depressive symptoms among youth with overweight/obesity. Linear regression models (adjusted for age, BMI, parental education, percent poverty) were used to examine cross-sectional (wave II, 1996, n = 3898, M _age = 15.9, SD = 0.13) and longitudinal (from wave II to IV, 1996-2008/2009, n = 2738, M _age = 28.5, SD = 0.06) associations between weight misperception and depressive symptoms (Center for Epidemiologic Studies-Depression Scale) in a subsample of White, Black, Asian, Hispanic, and Multi-racial male and female youth with overweight/obesity participating in the National Longitudinal Study of Adolescent Health. Average BMI was 29.0 (0.16) at wave II and 35.7 (0.23) at wave IV. Thirty-two percent misperceived their weight status as average weight (n = 1151, 30 %) or underweight (n = 99, 3 %). In fully adjusted cross-sectional models, White (β = -1.92, 95 % CI = -2.79, -1.06) and Multi-racial (β = -4.43, 95 % CI = -6.90, -1.95) youth who perceived themselves as average weight had significantly lower depressive symptoms compared to accurate weight-perceivers. In fully adjusted longitudinal models, White youth (β = -0.41, 95 % CI = -0.81, -0.004) who perceived themselves as average weight had significantly lower depressive symptoms 12 years later. Findings suggest that weight misperception may be protective against depression among White adolescents and young adults with overweight/obesity. Clinical and population interventions should consider potential harmful effects of correcting weight misperceptions on the mental health of youth with overweight/obesity.

Contextual Effects of Neighborhoods and Schools on Adolescent and Young Adult Marijuana Use in the United States

Little is known about the unique contribution of schools vs neighborhoods in driving adolescent marijuana use. This study examined the relative contribution of each setting and the influence of school and neighborhood socioeconomic status on use. We performed a series of cross-classified multilevel logistic models predicting past 30-day adolescent (N = 18 329) and young adult (N = 13 908) marijuana use using data from Add Health. Marijuana use differed by age, sex, race/ethnicity, and public assistance in adjusted models. Variance parameters indicated a high degree of clustering by school (σ2 = 0.30) and less pronounced clustering by neighborhood (σ2 = 0.06) in adolescence when accounting for both levels simultaneously in a cross-classified multilevel model. Clustering by school persisted into young adulthood (σ2 = 0.08). Parental receipt of public assistance increased the likelihood of use during adolescence (odds ratio = 1.39; 95% confidence interval: 1.19–1.59), and higher parental education was associated with increased likelihood of use in young adulthood. These findings indicate that both contexts may be promising locations for intervention.

Protective Misperception? Prospective Study of Weight Self-Perception and Blood Pressure in Adolescents With Overweight and Obesity

PURPOSE

Underestimating one's weight is often seen as a barrier to weight loss. However, recent research has shown that weight underperception may be beneficial, with lower future weight gain and fewer depressive symptoms. Here, we examine the relationship between adolescent weight underperception and future blood pressure.

METHODS

Using data from the National Longitudinal Study of Adolescent to Adult Health, we obtained a nationally representative sample of 2,463 adolescents with overweight and obesity (students in grades 8-12 in 1996). We used multivariable linear regression to prospectively examine the relationship between weight self-perception in adolescence and blood pressure in adulthood (year 2008; follow-up rate 80.3%), controlling for age, gender, race/ethnicity, smoking, alcohol consumption, education level, household income, and body mass index. Additional analyses were stratified by gender and race/ethnicity.

RESULTS

Youth with overweight/obesity who underperceived their weight had lower blood pressure in adulthood than those who perceived themselves to be overweight. The decrease in systolic blood pressure was -2.5 mm Hg (95% confidence interval: -4.3, -0.7; p = .006). Although the interaction by gender was statistically insignificant (p = .289), important differences appeared upon stratification by gender. Young men showed no significant difference in adult blood pressure related to weight self-perception. Conversely, in young women, weight underperception was associated with an average decrease in systolic blood pressure of -4.3 mm Hg (95% confidence interval: -7.0, -1.7; p = .002).

CONCLUSIONS

Contrary to conventional wisdom, weight underperception is associated with improved health markers in young women. The observed differences in blood pressure are clinically relevant in magnitude, and interventions to correct weight underperception should be re-examined for unintended consequences.

Do all-cause revisit rates reflect the quality of pediatric surgical care provided during index encounters?

PURPOSE

The purpose of this study was to compare the relatedness of revisits to the index surgical encounter across different pediatric surgical procedures and to explore whether all-cause revisit rates are an accurate surrogate measure for related revisits in this cohort of children.

METHODS

We reviewed all-cause revisits occurring within ninety days of the thirty most commonly performed pediatric surgical procedures at 44 children's hospitals between 1/1/2012 and 3/31/2015. For each condition, a team of four surgeons reviewed revisit diagnoses and reached consensus around relatedness to the index surgical encounter. Chi-squared tests were used to test for variation in all-cause and related revisits among procedures. Spearman's correlation coefficient was used to measure the association between rankings of procedures by their all-cause and related revisit rates.

RESULTS

144,535 index encounters were analyzed with an overall revisit rate of 15.0% (21,732). Significant variation was found in both the rates of all-cause revisits among procedures (ranges: 7.6-68.4%, p<0.0001), and in the relative proportions of revisits related the index surgical encounter (range: 0% to 77%, p<0.0001). Poor correlation was found between procedure rankings based on all-cause revisit rates and revisit rates related to the index admission (r=0.33, p=0.07).

CONCLUSIONS

The relative proportion of revisits related to the index encounter varies significantly across pediatric surgical conditions, and poor correlation exists at the procedure-level between all-cause and related revisits rates.

Quality of pediatric abdominal CT scans performed at a dedicated children's hospital and its referring institutions: a multifactorial evaluation

BACKGROUND

Pediatric patients requiring transfer to a dedicated children's hospital from an outside institution may undergo CT imaging as part of their evaluation. Whether this imaging is performed prior to or after transfer has been shown to impact the radiation dose imparted to the patient. Other quality variables could also be affected by the pediatric experience and expertise of the scanning institution.

OBJECTIVE

To identify differences in quality between abdominal CT scans and reports performed at a dedicated children's hospital, and those performed at referring institutions.

MATERIALS AND METHODS

Fifty consecutive pediatric abdominal CT scans performed at outside institutions were matched (for age, gender and indication) with 50 CT scans performed at a dedicated freestanding children's hospital. We analyzed the scans for technical parameters, report findings, correlation with final clinical diagnosis, and clinical utility. Technical evaluation included use of intravenous and oral contrast agents, anatomical coverage, number of scan phases and size-specific dose estimate (SSDE) for each scan. Outside institution scans were re-reported when the child was admitted to the children's hospital; they were also re-interpreted for this study by children's hospital radiologists who were provided with only the referral information given in the outside institution's report. Anonymized original outside institutional reports and children's hospital admission re-reports were analyzed by two emergency medicine physicians for ease of understanding, degree to which the clinical question was answered, and level of confidence in the report.

RESULTS

Mean SSDE was lower (8.68) for children's hospital scans, as compared to outside institution scans (13.29, P = 0.03). Concordance with final clinical diagnosis was significantly lower for original outside institution reports (38/48, 79%) than for both the admission and study children's hospital reports (48/50, 96%; P = 0.005). Children's hospital admission reports were rated higher than outside institution reports for completeness, ease of understanding, answering of clinical question, and level of confidence of the report (P < 0.001).

CONCLUSION

Pediatric abdominal CT scans performed and interpreted at a dedicated children's hospital are associated with higher technical quality, lower radiation dose and a more clinically useful report than those performed at referring institutions.
