Assessing Alternative Approaches for Wound Closure in a National Pediatric Learning Health System.

INTRODUCTION: Our objective was to perform a feasibility study using real-world data from a learning health system (LHS) to describe current practice patterns of wound closure and explore differences in outcomes associated with the use of tissue adhesives and other methods of wound closure in the pediatric surgical population to inform a potentially large study. METHODS: A multi-institutional cross-sectional study was performed of a random sample of patients <18 y-old who underwent laparoscopic appendectomy, open or laparoscopic inguinal hernia repair, umbilical hernia repair, or repair of traumatic laceration from January 1, 2019, to December 31, 2019. Sociodemographic and operative characteristics were obtained from 6 PEDSnet (a national pediatric LHS) children's hospitals and OneFlorida Clinical Research Consortium (a PCORnet collaboration across 14 academic health systems). Additional clinical data elements were collected via chart review. RESULTS: Of the 692 patients included, 182 (26.3%) had appendectomies, 155 (22.4%) inguinal hernia repairs, 163 (23.6%) umbilical hernia repairs, and 192 (27.8%) traumatic lacerations. Of the 500 surgical incisions, sutures with tissue adhesives were the most frequently used (n = 211, 42.2%), followed by sutures with adhesive strips (n = 176, 35.2%), and sutures only (n = 72, 14.4%). Most traumatic lacerations were repaired with sutures only (n = 127, 64.5%). The overall wound-related complication rate was 3.0% and resumption of normal activities was recommended at a median of 14 d (interquartile ranges 14-14). CONCLUSIONS: The LHS represents an efficient tool to identify cohorts of pediatric surgical patients to perform comparative effectiveness research using real-world data to support medical and surgical products/devices in children.

Faculty Physician and Trainee Experiences with Micro- and Macroaggressions: a Qualitative Study.

BACKGROUND: Micro- and macroaggressions are often stereotype threats that can have detrimental effects on the recipients. Survey data shows that these aggressions are happening. However, there are few qualitative studies on trainees and faculty physicians' experiences with such aggressions and their impact. OBJECTIVE: Explore how micro- and macroaggressions impact physician trainees and faculty. DESIGN, SETTING, PARTICIPANTS: Virtual, one-on-one, semi-structured interviews were conducted between February and September 2021, among 14 physicians and trainees (medical students, residents, fellows, and faculty) at a tertiary, urban, US academic medical center and its associated hospitals. Participants shared their experiences with micro- and macroaggressions in training and the workplace, as well as their thoughts on intervention and education. APPROACH: Qualitative interviews; grounded theory approach KEY RESULTS: A total of 14 physicians and trainees (5 faculty, 2 fellows, 5 residents, 2 students; 11 [79%] women) participated. Four themes with multiple subthemes surfaced: definition, the moment an aggression is experienced, aftereffect of an aggression, and education and training. While general definitions of micro- and macroaggressions were similar among participants, some may have overlooked the inclusion of a marginalized group as central to each term. Both types of aggressions had a range of effects on participants, with faculty noting a cumulative effect. Institutional diversity was identified as a key source of support. Ideas on how to combat such acts included mandatory educational programs and policies, with the acknowledgment that much effort and time are necessary to change mindset and culture. CONCLUSIONS: Faculty physicians and medical trainees shared their personal experiences with micro- and macroaggressions during work and training. Participants described various emotions in the moment but also noted that these aggressions often had lasting impacts. They recognized the challenges of finding a solution to micro- and macroaggressions. Institution-wide education was favored by many as a first step.

Complex relationship between low albumin level and poor outcome after lower extremity procedures for peripheral artery disease.

OBJECTIVE: A low albumin level has been associated with poor outcome, including death, in surgical patients. The mechanistic relationship, however, is more complex than simply nutritional. As studies are scant in the vascular population, we sought to examine the association of low albumin level with outcomes in patients undergoing open and endovascular lower extremity procedures for peripheral artery disease. METHODS: Patients with peripheral artery disease undergoing lower extremity procedures (2008-2015) were selected from Cerner Health Facts database (Cerner Corporation, Kansas City, Mo) using International Classification of Diseases, Ninth Revision diagnosis and procedure codes. Age, sex, disease severity, and other comorbidities were captured. Outcomes were identified using codes and encounter data. A χ2analysis and multivariable logistic regression were performed. RESULTS: There were 6170 patients evaluated; 4562 (74%) underwent endovascular procedures and 1608 (26%) underwent open surgery. Low albumin level (<3.5 g/dL) was associated with age ≥80 years (23.1% vs 16.3% normal; P < .0001), black race (21% vs 11.6% normal; P < .0001), tissue loss (38% vs 16.4% normal; P < .0001), and higher Charlson index (mean, 3.1 vs 2.2 in the normal group; P < .0001). Low albumin level was also associated with longer length of stay (4.9 vs 2.2 days normal; P < .0001), higher in-hospital mortality (1.9% vs 0.3% normal; P < .0001), and higher 30-day readmission (15% vs 12.7% normal; P = .02). Multivariable analysis demonstrated that low albumin level was strongly associated with in-hospital death (odds ratio [OR], 5.23; 95% confidence interval [CI], 2.00-13.70), infection (OR, 2.51; 95% CI, 1.96-3.22), renal failure (OR, 2.61; 95% CI, 1.79-3.79), and cardiac complications (OR, 2.59; 95% CI, 1.69-3.96). After multivariable adjustment, there was no association between albumin level and 30-day readmission. CONCLUSIONS: Low preoperative albumin levels are associated with in-hospital death, prolonged length of stay, and severe morbidity after open and endovascular lower extremity procedures. As the majority of lower extremity procedures are elective, serious consideration should be given to deferring elective procedures until albumin levels have been optimized. Because of the pleiotropic effects of albumin, including antiplatelet and inflammatory function, study of this complex relationship may offer insights into how best to integrate this novel biomarker into vascular surgery decision-making.

Delaying Cochlear Implantation Impacts Postoperative Speech Perception of Nontraditional Pediatric Candidates.

INTRODUCTION: As pediatric cochlear implant (CI) candidacy expands, children with greater degrees of residual hearing are receiving CIs. These nontraditional candidates have audiometric thresholds that meet adult manufacturer labeling but are better than current pediatric guidelines allow. The purpose of this study was to determine the impact of delayed cochlear implantation on speech perception in nontraditional pediatric CI recipients. METHODS: Pediatric CI recipients with a history of progressive hearing loss and a preoperative 4-frequency pure-tone average of ≤75 dB HL at the time of implantation were considered for this retrospective study. Preoperative serial audiograms and word recognition scores were reviewed, and a method was created to establish a date when each individual ear 1st met nontraditional candidacy. The length of time between the date of candidacy and implantation was calculated and defined as the "delay time." A multiple linear regression investigated delay time, age at surgery, surgery type (1st vs. 2nd side), and array type as predictive factors of maximum postoperative Consonant-Nucleus-Consonant (CNC) word scores. A one-way ANCOVA was performed comparing the postoperative CNC scores between subjects grouped by delay time. RESULTS: A significant regression was found (F(4, 38) = 5.167, p = 0.002, R2 = 0.353). Both age at implantation (p = 0.023) and delay time (p = 0.002) predicted CNC word scores. Longer delay time was associated with poorer word recognition scores, while older age at implantation correlated with higher CNC word scores in this progressive hearing loss group. A significant difference was noted between subjects implanted with <1 year of delay and those with 3 or more years of delay (p = 0.003). All ears implanted within a year of candidacy achieved word recognition abilities that are generally accepted as above average (M = 84.91). CONCLUSION: CI candidacy for adults has evolved to allow for greater degrees of residual hearing, while audiometric guidelines for children have not changed since 2000. Our findings suggest that delay of cochlear implantation, even for children with significant levels of residual hearing, leads to poorer outcomes. Modified candidacy guidelines for children should be established to expedite referral to multidisciplinary CI teams and minimize delays in this population.

Web-based LGBT cultural competency training intervention for oncologists: Pilot study results.

BACKGROUND: Lesbian, gay, bisexual, and transgender (LGBT) cancer patients experience substantial health disparities, including poorer overall health and lower satisfaction with their cancer care than their heterosexual and cisgender counterparts, which may be due in part to a lack of culturally competent providers. To address these disparities, a web-based LGBT cultural competency training tailored to oncologists was developed by an interdisciplinary team of scientists, LGBT cancer survivors, cultural competency experts, oncologists, a web designer, and an instructional designer. METHODS: Oncologists (n = 44) were recruited from 3 academic cancer centers in Florida. Participants were administered the LGBT cultural competency training Curriculum for Oncologists on LGBT populations to Optimize Relevance and Skills (COLORS) and completed pre- and posttraining measures regarding LGBT-related knowledge, attitudes (including general negative attitudes and health care-related attitudes), and clinical practices. After the training, participants completed training acceptability measures. RESULTS: Of the 44 participants, 33 (75%) completed the COLORS training. Participants were 55% non-Hispanic white, 63% male, and had a mean age of 47 years. Participants demonstrated significant improvements in LGBT-related knowledge (t = -4.9, P < .001), attitudes (Z = -3.0, P = .002; t = -2.5, P = .019), and clinical practices (Z = -3.5, P < .001) after completing the COLORS training (Wilcoxon signed rank tests were used for nonnormally distributed variables). Moreover, training acceptability was high, with 82% of participants rating the training as high quality, and 97% being willing to recommend the training to a colleague. CONCLUSION: The COLORS training is both feasible to administer and acceptable for use with oncologists, and may improve oncologists' LGBT-related knowledge, attitudes, and clinical practices. Larger trials are needed to examine the training's effectiveness in reducing LGBT cancer disparities, as well as its applicability to other types of care providers.

EZH2 Regulates the Developmental Timing of Effectors of the Pre-Antigen Receptor Checkpoints.

The histone methyltransferase EZH2 is required for B and T cell development; however, the molecular mechanisms underlying this requirement remain elusive. In a murine model of lymphoid-specific EZH2 deficiency we found that EZH2 was required for proper development of adaptive, but not innate, lymphoid cells. In adaptive lymphoid cells EZH2 prevented the premature expression of Cdkn2a and the consequent stabilization of p53, an effector of the pre-Ag receptor checkpoints. Deletion of Cdkn2a in EZH2-deficient lymphocytes prevented p53 stabilization, extended lymphocyte survival, and restored differentiation resulting in the generation of mature B and T lymphocytes. Our results uncover a crucial role for EZH2 in adaptive lymphocytes to control the developmental timing of effectors of the pre-Ag receptor checkpoints.

Electric-Acoustic Stimulation Outcomes in Children.

OBJECTIVES: This study investigates outcomes in children fit with electric-acoustic stimulation (EAS) and addresses three main questions: (1) Are outcomes with EAS superior to outcomes with conventional electric-only stimulation in children? (2) Do children with residual hearing benefit from EAS and conventional electric-only stimulation when compared with the preoperative hearing aid (HA) condition? (3) Can children with residual hearing derive benefit from EAS after several years of listening with conventional electric-only stimulation? DESIGN: Sixteen pediatric cochlear implant (CI) recipients between 4 and 16 years of age with an unaided low-frequency pure tone average of 75 dB HL in the implanted ear were included in two study arms. Arm 1 included new recipients, and Arm 2 included children with at least 1 year of CI experience. Using a within-subject design, participants were evaluated unilaterally with the Consonant-Nucleus-Consonant (CNC) word list in quiet and the Baby Bio at a +5 dB SNR using an EAS program and a conventional full electric (FE) program. Arm 1 participants' scores were also compared with preoperative scores. RESULTS: Speech perception outcomes were statistically higher with the EAS program than the FE program. For new recipients, scores were significantly higher with EAS than preoperative HA scores for both the CNC and Baby Bio in noise; however, after 6 months of device use, results in the FE condition were not significantly better than preoperative scores. Long-term FE users benefited from EAS over their FE programs based on CNC word scores. CONCLUSIONS: Whether newly implanted or long-term CI users, children with residual hearing after CI surgery can benefit from EAS. Cochlear implantation with EAS fitting is a viable option for children with HAs who have residual hearing but have insufficient access to high-frequency sounds and poor speech perception.

Acoustically evoked auditory change complex in children with auditory neuropathy spectrum disorder: a potential objective tool for identifying cochlear implant candidates.

OBJECTIVES: The overall aim of the study was to evaluate the feasibility of using electrophysiological measures of the auditory change complex (ACC) to identify candidates for cochlear implantation in children with auditory neuropathy spectrum disorder (ANSD). To achieve this overall aim, this study (1) assessed the feasibility of measuring the ACC evoked by temporal gaps in a group of children with ANSD across a wide age range and (2) investigated the association between gap detection thresholds (GDTs) measured by the ACC recordings and open-set speech-perception performance in these subjects. DESIGN: Nineteen children with bilateral ANSD ranging in age between 1.9 and 14.9 years (mean: 7.8 years) participated in this study. Electrophysiological recordings of the auditory event-related potential (ERP), including the onset ERP response and the ACC, were completed in all subjects and open-set speech perception was evaluated for a subgroup of 16 subjects. For the ERP recordings, the stimulus was a Gaussian noise presented through ER-3A insert earphones to the test ear. Two stimulation conditions were used. In the "control condition," the stimulus was an 800-msec Gaussian noise. In the "gapped condition," the stimuli were two noise segments, each being 400 msec in duration, separated by one of five gaps (i.e., 5, 10, 20, 50, or 100 msec). The interstimulation interval was 1200 msec. The aided open-set speech perception ability was assessed using the Phonetically Balanced Kindergarten (PBK) word lists presented at 60 dB SPL using recorded testing material in a sound booth. For speech perception tests, subjects wore their hearing aids at the settings recommended by their clinical audiologists. For a subgroup of five subjects, psychophysical GDTs for the Gaussian noise were also assessed using a three-interval, three-alternative forced-choice procedure. RESULTS: Responses evoked by the onset of the Gaussian noise (i.e., onset responses) were recorded in all stimulation conditions from all subjects tested in this study. The presence/absence, peak latency and amplitude, and response width of the onset response did not correlate with aided PBK word scores. The objective GDTs measured with the ACC recordings from 17 subjects ranged from 10 to 100 msec. The ACC was not recorded from two subjects for any gap durations tested in this study. There was a robust negative correlation between objective GDTs and aided PBK word scores. In general, subjects with prolonged objective GDTs showed low-aided PBK word scores. GDTs measured using electrophysiological recordings of the ACC correlated well with those measured using psychophysical procedures in four of five subjects who were evaluated using both procedures. CONCLUSIONS: The clinical application of the onset response in predicting open-set speech-perception ability is relatively limited in children with ANSD. The ACC recordings can be used to objectively evaluate temporal resolution abilities in children with ANSD having no severe comorbidities, and who are older than 1.9 years. The ACC can potentially be used as an objective tool to identify poor performers among children with ANSD using properly fit amplification, and who are thus, cochlear implant candidates.

Safety and Early Outcomes of Cochlear Implantation of Nucleus Devices in Infants: A Multi-Centre Study.

This multi-center study examined the safety and effectiveness of cochlear implantation of children between 9 and 11 months of age. The intended impact was to support practice regarding candidacy assessment and prognostic counseling of pediatric cochlear implant candidates. Data in the clinical chart of children implanted at 9-11 months of age with Cochlear Ltd devices at five cochlear implant centers in the United States and Canada were included in analyses. The study included data from two cohorts implanted with one or two Nucleus devices during the periods of January 1, 2012-December 31, 2017 (Cohort 1, n = 83) or between January 1, 2018 and May 15, 2020 (Cohort 2, n = 50). Major adverse events (requiring another procedure/hospitalization) and minor adverse events (managed with medication alone or underwent an expected course of treatment that did not require surgery or hospitalization) out to 2 years post-implant were monitored and outcomes measured by audiometric thresholds and parent-reports on the IT-MAIS and LittlEARS questionnaires were collected. Results revealed 60 adverse events in 41 children and 227 ears implanted (26%) of which 14 major events occurred in 11 children; all were transitory and resolved. Improved hearing with cochlear implant use was shown in all outcome measures. Findings reveal that the procedure is safe for infants and that they show clear benefits of cochlear implantation including increased audibility and hearing development.

Acceptability of HPV self-collection: A qualitative study of Black women living with type II diabetes and social vulnerability.

Introduction: Human papillomavirus (HPV) causes 99.7% of cervical cancer cases. Cervical cancer is preventable through early detection via HPV testing. However, the number of women screened for cervical cancer has not increased in the last several years. Lower screening rates among women living in high poverty and social vulnerability areas, Black women, and women with chronic co-morbidities (e.g., type 2 diabetes (T2D)) are associated with their higher cervical cancer mortality rates. When screened, Black women are more likely to be diagnosed at later stages and die from cervical cancer. HPV self-collection decreases barriers to cervical cancer screening and can help lessen disparities among underserved women. This study aimed to examine the acceptability of HPV self-collection among Black women with T2D living in socially vulnerable communities. Methods: Qualitative semi-structured interviews were conducted with 29 Black women with T2D living in communities with high social vulnerability. The Health Belief Model informed the development of the interview guide to gather data on the acceptability of HPV self-collection. Results: Three main themes aligned with the Health Belief Model were identified: (1) HPV self-collection provides a comfortable alternative to in-clinic HPV testing (perceived benefits); (2) HPV self-collection would result in awareness of current HPV status (health motivation); and (3) Women were concerned about collecting their sample accurately (perceived barriers). Discussion/Conclusion: Black women with T2D living in communities with high social vulnerability identified multiple benefits of cervical cancer screening through HPV self-collection. Women are concerned about their ability to collect these samples correctly. Our findings call for future studies focusing on increasing self-efficacy and skills to collect HPV samples among Black women with chronic conditions like T2D who reside in underserved communities with high social vulnerability.

Use of Electronic Health Records to Characterize Patients with Uncontrolled Hypertension in Two Large Health System Networks.

Background: Improving hypertension control is a public health priority. However, consistent identification of uncontrolled hypertension using computable definitions in electronic health records (EHR) across health systems remains uncertain. Methods: In this retrospective cohort study, we applied two computable definitions to the EHR data to identify patients with controlled and uncontrolled hypertension and to evaluate differences in characteristics, treatment, and clinical outcomes between these patient populations. We included adult patients (≥ 18 years) with hypertension receiving ambulatory care within Yale-New Haven Health System (YNHHS; a large US health system) and OneFlorida Clinical Research Consortium (OneFlorida; a Clinical Research Network comprised of 16 health systems) between October 2015 and December 2018. We identified patients with controlled and uncontrolled hypertension based on either a single blood pressure (BP) measurement from a randomly selected visit or all BP measurements recorded between hypertension identification and the randomly selected visit). Results: Overall, 253,207 and 182,827 adults at YNHHS and OneFlorida were identified as having hypertension. Of these patients, 83.1% at YNHHS and 76.8% at OneFlorida were identified using ICD-10-CM codes, whereas 16.9% and 23.2%, respectively, were identified using elevated BP measurements (≥ 140/90 mmHg). Uncontrolled hypertension was observed among 32.5% and 43.7% of patients at YNHHS and OneFlorida, respectively. Uncontrolled hypertension was disproportionately higher among Black patients when compared with White patients (38.9% versus 31.5% in YNHHS; p < 0.001; 49.7% versus 41.2% in OneFlorida; p < 0.001). Medication prescription for hypertension management was more common in patients with uncontrolled hypertension when compared with those with controlled hypertension (overall treatment rate: 39.3% versus 37.3% in YNHHS; p = 0.04; 42.2% versus 34.8% in OneFlorida; p < 0.001). Patients with controlled and uncontrolled hypertension had similar rates of short-term (at 3 and 6 months) and long-term (at 12 and 24 months) clinical outcomes. The two computable definitions generated consistent results. Conclusions: Our findings illustrate the potential of leveraging EHR data, employing computable definitions, to conduct effective digital population surveillance in the realm of hypertension management.

Gap detection measured with electrically evoked auditory event-related potentials and speech-perception abilities in children with auditory neuropathy spectrum disorder.

OBJECTIVES: This study aimed (1) to investigate the feasibility of recording the electrically evoked auditory event-related potential (eERP), including the onset P1-N1-P2 complex and the electrically evoked auditory change complex (EACC) in response to temporal gaps, in children with auditory neuropathy spectrum disorder (ANSD); and (2) to evaluate the relationship between these measures and speech-perception abilities in these subjects. DESIGN: Fifteen ANSD children who are Cochlear Nucleus device users participated in this study. For each subject, the speech-processor microphone was bypassed and the eERPs were elicited by direct stimulation of one mid-array electrode (electrode 12). The stimulus was a train of biphasic current pulses 800 msec in duration. Two basic stimulation conditions were used to elicit the eERP. In the no-gap condition, the entire pulse train was delivered uninterrupted to electrode 12, and the onset P1-N1-P2 complex was measured relative to the stimulus onset. In the gapped condition, the stimulus consisted of two pulse train bursts, each being 400 msec in duration, presented sequentially on the same electrode and separated by one of five gaps (i.e., 5, 10, 20, 50, and 100 msec). Open-set speech-perception ability of these subjects with ANSD was assessed using the phonetically balanced kindergarten (PBK) word lists presented at 60 dB SPL, using monitored live voice in a sound booth. RESULTS: The eERPs were recorded from all subjects with ANSD who participated in this study. There were no significant differences in test-retest reliability, root mean square amplitude or P1 latency for the onset P1-N1-P2 complex between subjects with good (>70% correct on PBK words) and poorer speech-perception performance. In general, the EACC showed less mature morphological characteristics than the onset P1-N1-P2 response recorded from the same subject. There was a robust correlation between the PBK word scores and the EACC thresholds for gap detection. Subjects with poorer speech-perception performance showed larger EACC thresholds in this study. CONCLUSIONS: These results demonstrate the feasibility of recording eERPs from implanted children with ANSD, using direct electrical stimulation. Temporal-processing deficits, as demonstrated by large EACC thresholds for gap detection, might account in part for the poor speech-perception performances observed in a subgroup of implanted subjects with ANSD. This finding suggests that the EACC elicited by changes in temporal continuity (i.e., gap) holds promise as a predictor of speech-perception ability among implanted children with ANSD.

Patients' comfort with and receipt of health risk assessments during routine dental visits: Results from the South Atlantic region of the US National Dental Practice-Based Research Network.

OBJECTIVES: To understand patients' comfort with health risk assessments (HRAs) and patient and dentist factors associated with the provision of HRAs. METHODS: In this cross-sectional study, 857 patients seen by 30 dental practitioners in the United States National Dental Practice-Based Research Network reported their comfort receiving HRA for six risk factors (tobacco use, alcohol use, dietary sugar intake, human immunodeficiency virus risks, human papillomavirus risks and existing medical conditions) and whether they discussed any of the risk factors during their visits. Multi-level logistic models were used to examine the impacts of patient, practitioner, practice characteristics on the (1) number of risk factors patients were comfortable discussing and (2) number of risk factors assessed in the current dental visit. RESULTS: Only a small percentage (4%) of patients reported being uncomfortable receiving any HRA during their dental visits. However, over half of the patients (53%) reported that they did not receive any HRAs during the current visit. In the regression analyses, patients who were older, male and from the suburban were more likely to be comfortable with more HRAs. Dentists were more likely to provide HRA if they were younger, not non-Hispanic white, less likely to feel that providing HRAs was beyond their scope of practice, yet more likely to feel occasional discomfort in providing HRA. CONCLUSIONS: Interventions should focus on reducing dental practitioner perception that conducting HRAs is beyond their scope of practice and standardizing screening assessments for multiple risk factors.

Disparities Contributing to Late-Stage Diagnosis of Lung, Colorectal, Breast, and Cervical Cancers: Rural and Urban Poverty in Florida.

Despite advances in cancer screening, late-stage cancer diagnosis is still a major cause of morbidity and mortality in the United States. In this study, we aim to understand demographic and geographic factors associated with receiving a late-stage diagnosis (LSD) of lung, colorectal, breast, or cervical cancer. (1) Methods: We analyzed data of patients with a cancer diagnosis between 2016 and 2020 from the Florida Cancer Data System (FCDS), a statewide population-based registry. To investigate correlates of LSD, we estimated multi-variable logistic regression models for each cancer while controlling for age, sex, race, insurance, and census tract rurality and poverty. (2) Results: Patients from high-poverty rural areas had higher odds for LSD of lung (OR = 1.23, 95% CI (1.10, 1.37)) and breast cancer (OR = 1.31, 95% CI (1.17,1.47)) than patients from low-poverty urban areas. Patients in high-poverty urban areas saw higher odds of LSD for lung (OR = 1.05 95% CI (1.00, 1.09)), breast (OR = 1.10, 95% CI (1.06, 1.14)), and cervical cancer (OR = 1.19, 95% CI (1.03, 1.37)). (3) Conclusions: Financial barriers contributing to decreased access to care likely drive LSD for cancer in rural and urban communities of Florida.

Medication prescription for hypertension management was more common in patients with uncontrolled hypertension when compared with those with controlled hypertension (overall treatment rate: 39.3% versus 37.3% in YNHHS; p=0.04; 42.2% versus 34.8% in OneFlorida; p<0.001). Patients with controlled and uncontrolled hypertension had similar rates of short-term (at 3 and 6 months) and long-term (at 12 and 24 months) clinical outcomes. The two computable definitions generated consistent results. Conclusions: Computable definitions can be successfully applied to health system EHR data to conduct population surveillance for hypertension and identify patients with uncontrolled hypertension who may benefit from additional treatment.

Correlation Between Polypharmacy and Frailty Among Thai Older Persons Living with HIV.

Polypharmacy and frailty are correlated in Persons Living with HIV (PLWH) in the United States, but little is known about their correlation in resource-limited settings. Our cross-section study evaluated the correlation between polypharmacy and frailty among Thai 324 virally suppressed PLWH and 132 uninfected patients aged ≥50 between March 2016 and April 2017. The primary predictor was the number of patient-reported non-antiretroviral therapy (ART) medications. The outcome was having additional domain of the five Fried frailty phenotype domains (0 = normal, 1-2 = prefrail, >3 = frail). Most participants were male (63% PLWH, 67% uninfected) with few comorbidities (1.4 PLWH, 0.9 uninfected) and small median number of non-ART medications (2 PLWH, 1 uninfected). Frailty was uncommon (8.6% PLWH, 3.8% uninfected). Each additional non-ART medication correlated with 6% increased likelihood of having additional frailty domain among PLWH (95% CI: 0.002-0.11, p = .04) but not statistically significant among the uninfected. The association between polypharmacy and frailty is more pronounced in Thai PLWH than in participants without HIV. Further study is warranted to confirm this association in other resource-limited settings and explore potential deprescribing practices.

Florida Medicaid Children's Receipt of First-Line Psychosocial Care Prior to Antipsychotic Initiation.

BACKGROUND AND OBJECTIVE: First-line, nonpharmacological therapy is recommended for many pediatric mental health (MH) conditions prior to initiating antipsychotic prescription therapies. Many children do not receive these recommended services, despite the known association between antipsychotic medications and metabolic dysfunction. The main objective of this study was to quantify the association among children's MH diagnosis categories, sociodemographic characteristics and receipt of first-line psychosocial care among children in Florida Medicaid METHODS: Florida Medicaid enrollment, healthcare and pharmacy claims were used for this multivariate analysis. Children were assigned to condition clusters wherein related diagnoses were grouped into clinically relevant categories. A total of 7704 children were included in the final analysis. RESULTS: Twenty-four percent of children in Florida Medicaid do not receive first-line, nonpharmacological psychosocial care. Age was significantly associated with not receiving psychosocial services, with older children less likely to receive. Non-Hispanic White children as well as those living in rural areas had lower odds of receiving behavioral intervention prior to initiating antipsychotics. Children with mood-disorders, behavior problems, anxiety and stress related disorders were more likely to receive first-line psychosocial care. CONCLUSIONS: This study provides an important understanding of the variability in receipt of first-line psychosocial care before antipsychotic medication initiation among children in Medicaid based on sociodemographic and MH health characteristics. These analyses can be used to develop quality improvement initiatives targeted toward children that are most vulnerable for not receiving recommended care.

The Impact of Race-Ethnicity and Diagnosis of Alzheimer's Disease and Related Dementias on Mammography Use.

Breast cancer screening (BCS) with mammography is a crucial method for improving cancer survival. In this study, we examined the association of Alzheimer's disease (AD) and AD-related dementias (ADRD) diagnosis and race-ethnicity with mammography use in BCS-eligible women. In the real-world data from the OneFlorida+ Clinical Research Network, we extracted a cohort of 21,715 BCS-eligible women with ADRD and a matching comparison cohort of 65,145 BCS-eligible women without ADRD. In multivariable regression analysis, BCS-eligible women with ADRD were more likely to undergo a mammography than the BCS-eligible women without ADRD (odds ratio [OR] = 1.19, 95% confidence interval [CI] = 1.13-1.26). Stratified by race-ethnicity, BCS-eligible Hispanic women with ADRD were more likely to undergo a mammography (OR = 1.56, 95% CI = 1.39-1.75), whereas BCS-eligible non-Hispanic black (OR = 0.72, 95% CI = 0.62-0.83) and non-Hispanic other (OR = 0.65, 95% CI = 0.45-0.93) women with ADRD were less likely to undergo a mammography. This study was the first to report the impact of ADRD diagnosis and race-ethnicity on mammography use in BCS-eligible women using real-world data. Our results suggest ADRD patients might be undergoing BCS without detailed guidelines to maximize benefits and avoid harms.

Enhancing Quality Measurement With Clinical Information: A Use Case of Body Mass Index Change Among Children Taking Second Generation Antipsychotics.

OBJECTIVE: We sought to examine the extent to which body mass index (BMI) was available in electronic health records for Florida Medicaid recipients aged 5 to 18 years taking Second-Generation Antipsychotics (SGAP). We also sought to illustrate how clinical data can be used to identify children most at-risk for SGAP-induced weight gain, which cannot be done using process-focused measures. METHODS: Electronic health record (EHR) data and Medicaid claims were linked from 2013 to 2019. We quantified sociodemographic differences between children with and without pre- and post-BMI values. We developed a linear regression model of post-BMI to examine pre-post changes in BMI among 4 groups: 1) BH/SGAP+ children had behavioral health conditions and were taking SGAP; 2) BH/SGAP- children had behavioral health conditions without taking SGAP; 3) children with asthma; and 4) healthy children. RESULTS: Of 363,360 EHR-Medicaid linked children, 18,726 were BH/SGAP+. Roughly 4% of linked children and 8% of BH/SGAP+ children had both pre and post values of BMI required to assess quality of SGAP monitoring. The percentage varied with gender and race-ethnicity. The R2 for the regression model with all predictors was 0.865. Pre-post change in BMI differed significantly (P < .0001) among the groups, with more BMI gain among those taking SGAP, particularly those with higher baseline BMI. CONCLUSION: Meeting the 2030 Centers for Medicare and Medicaid Services goal of digital monitoring of quality of care will require continuing expansion of clinical encounter data capture to provide the data needed for digital quality monitoring. Using linked EHR and claims data allows identifying children at higher risk for SGAP-induced weight gain.

Use of real-world data and clinical registries to identify new uses of existing vascular endografts: combined use of GORE EXCLUDER Iliac Branch Endoprosthesis and GORE VIABAHN VBX Balloon Expandable Endoprosthesis.

Objective: To assess the feasibility of collecting, examining and reporting observational, real-world evidence regarding the novel use of the GORE EXCLUDER Iliac Branch Endoprosthesis (IBE) in conjunction with the GORE VIABAHN VBX Balloon Expandable Endoprosthesis (IBE+VBX stent graft). Design: Multicentre retrospective cohort study. Setting: Four real-world data sources were used: a national quality improvement registry, a statewide clinical research network, a regional quaternary health system and two tertiary academic medical centres. Participants: In total, 30 patients with 37 IBE+VBX stent graft were identified. Of those, the mean age was 72±10.2 years and 90% were male. The cohort was 77% white, 10% black, 3% Hispanic and 10% other. Main outcome measures: Outcome measures included: proportion of percutaneous vs open surgical access, intensive care admission, intensive care unit (ICU) length-of-stay (LOS), total LOS, postoperative complications, discharge disposition and 30-day mortality. Results: The majority (89%) of cases were performed percutaneously, 5% required surgical exposure following failed percutaneous access and 6% required open surgical exposure outright. Nearly half (43%) required intensive care admission with a median ICU LOS of 1 day (range: 1-2). Median total LOS was 1 day (IQR: 1-2). There were zero postoperative myocardial infarctions, zero reported leg embolisations and no reported reinterventions. Access site complications were described in 1 of 28 patients, manifesting as a haematoma or pseudoaneurysm. Ultimately, 97% were discharged to home and one patient was discharged to a nursing home or rehabilitation facility. There were no 30-day perioperative deaths. Conclusions: This project demonstrates the feasibility of identifying and integrating real-world evidence, as it pertains to an unapproved combination of endovascular devices (IBE+VBX stent graft), for short-term outcomes analysis. This new paradigm of evidence has potential to be used for device monitoring, submission to regulatory agencies, or consideration in indication expansions and approvals with further efforts to systematise data collection and transmission mechanisms.
