ABSTRACT

IMPORTANCE: Since implementation of the International Statistical Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) in the US, thousands of new or related codes have been added to represent clinical conditions. The widely used pediatric complex chronic condition (CCC) system required a major update from version 2 (V2) to version 3 (V3) to capture the range of clinical conditions represented in the ICD-10-CM.

OBJECTIVE: To update the CCC V3 system, creating V3, with new, missing, or retired codes; to reconceptualize the system’s use of technology codes; and to compare CCC V3 with V2.

DESIGN, SETTING, AND PARTICIPANTS: This repeated cross-sectional study examined US hospitalization data from the Pediatric Health Information System (PHIS) and the Medicaid Merative MarketScan Research Databases from January 1, 2009, to December 31, 2019, for all patients aged 0 to 18 years. Data were analyzed from March 1, 2023, to April 1, 2024.

EXPOSURES: The CCCs were identified in both data sources using the CCC V2 and V3 systems.

MAIN OUTCOMES AND MEASURES: The (1) percentage of pediatric hospitalizations associated with a CCC, (2) numbers of CCC body-system categories per patient, and (3) explanatory power for hospital length of stay and in-hospital mortality were compared over time for V3 vs V2.

RESULTS: Among 7 186 019 hospitalizations within PHIS, 54.3% patients were male, the median age was 4 years (IQR, 1-11 years), and 51.2% were aged 0 to 4 years). The CCC V2 identified 2 878 476 (40.1%) patients as having any CCC compared with 2 753 412 (38.3%) identified by V3. In addition, V2 identified 100 065 (1.4%) patients with transplant status compared with 146 683 (2.0%) by V3, and V2 identified 914 835 (12.7%) as having technology codes compared with 805 585 (11.2%) by V3. The 2 systems were similar in accounting for the number of CCC body-system categories per patient and in explaining variation in hospital length of stay and in-hospital mortality. For both V2 and V3, 10.0% of the variance in hospital length of stay and 12.0% of the variance in in-hospital mortality was explained by the presence of a CCC. Similar patterns were observed when analyzing the 2 999 420 Medicaid Merative MarketScan Research Databases’ hospitalizations (52.3% of patients were male, the median age was 1 year [IQR, 0-12 years], and 62.0% were 0 to 4 years old), except that the percentages of identified CCCs were all lower: V2 identified 758 110 hospitalizations (25.3%) with any CCC compared with 718 100 (23.9%) identified by V3.

CONCLUSIONS AND RELEVANCE: These results suggest that, moving forward, V3 should be used to identify CCCs, and ongoing, frequent updates to V3, using a transparent, structured process, will enable V3 to accurately reflect the evolving spectrum of clinical conditions represented in the ICD-10-CM.

ABSTRACT

IMPORTANCE: Technical skill in complex surgical procedures may affect clinical outcomes, and there is growing interest in understanding the clinical implications of surgeon proficiency levels.

OBJECTIVES: To determine whether surgeon scores representing technical skills of robot-assisted kidney surgery are associated with patient outcomes.

DESIGN, SETTING, AND PARTICIPANTS: This quality improvement study included 10 urological surgeons participating in a surgical collaborative in Michigan from July 2021 to September 2022. Each surgeon submitted up to 7 videos of themselves performing robot-assisted partial nephrectomy. Videos were segmented into 6 key steps, yielding 127 video clips for analysis. Each video clip was deidentified and distributed to at least 3 of the 24 blinded peer surgeons from the collaborative who also perform robot-assisted partial nephrectomy. Reviewers rated technical skill and provided written feedback. Statistical analysis was performed from May 2023 to January 2024.

MAIN OUTCOMES AND MEASURES: Reviewers scored each video clip using a validated instrument to assess technical skill for partial nephrectomy on a scale of 1 to 5 (higher scores indicating greater skill). For all submitting surgeons, outcomes from a clinical registry were assessed for length of stay (LOS) greater than 3 days, estimated blood loss (EBL) greater than 500 mL, warm ischemia time (WIT) greater than 30 minutes, positive surgical margin (PSM), 30-day emergency department (ED) visits, and 30-day readmission.

RESULTS: Among the 27 unique surgeons who participated in this study as reviewers and/or individuals performing the procedures, 3 (11%) were female, and the median age was 47 (IQR, 39-52) years. Risk-adjusted outcomes were associated with scores representing surgeon skills. The overall performance score ranged from 3.5 to 4.7 points with a mean (SD) of 4.1 (0.4) points. Greater skill was correlated with significantly lower rates of LOS greater than 3 days (-6.8% [95% CI, -8.3% to -5.2%]), EBL greater than 500 mL (-2.6% [95% CI, -3.0% to -2.1%]), PSM (-8.2% [95% CI, -9.2% to -7.2%]), ED visits (-3.9% [95% CI, -5.0% to -2.8%]), and readmissions (-5.7% [95% CI, -6.9% to -4.6%]) (P < .001 for all). Higher overall score was also associated with higher partial nephrectomy volume (β coefficient, 11.4 [95% CI, 10.0-12.7]; P < .001).

CONCLUSIONS AND RELEVANCE: In this quality improvement study on video-based evaluation of robot-assisted partial nephrectomy, higher technical skill was associated with lower rates of adverse clinical outcomes. These findings suggest that video-based evaluation plays a role in assessing surgical skill and can be used in quality improvement initiatives to improve patient care.

ABSTRACT

IMPORTANCE: Family-centered care recognizes families as central to child health and well-being and prioritizes clinician collaboration with families to ensure optimal pediatric care and outcomes. Clinician interpersonal sensitivity and communication skills are key to this approach.

OBJECTIVE: To examine perceptions of and factors associated with family-centered care among clinicians working in pediatric and congenital heart care.

DESIGN, SETTING, AND PARTICIPANTS: In this cross-sectional study, participants from diverse clinical disciplines (pediatric cardiology, cardiothoracic surgery, nursing, anesthesia, neonatology, intensive care, psychology, and others), completed an online survey between June 2020 and February 2021. Participants included physicians, surgeons, nurses, and allied and mental health professionals at an Australian quaternary pediatric hospital network. Statistical analysis was performed from August 2022 to June 2023.

MAIN OUTCOMES AND MEASURES: Family-centered care across 4 domains (showing interpersonal sensitivity, treating people respectfully, providing general information, and communicating specific information) was measured using the validated Measure of Processes of Care for Service Providers. Clinician burnout (emotional exhaustion, depersonalization, and personal accomplishment), confidence responding to families’ psychosocial needs, and psychological, clinical role, and sociodemographic factors were also assessed. Informed by theory, hierarchical linear regression was used to identify factors associated with family-centered care.

RESULTS: There were 212 clinicians (177 women [84.3%]; 153 nurses [72.2%], 32 physicians [15.1%], 22 allied and mental health professionals [10.4%], 5 surgeons [2.3%]; 170 [80.2%] aged 20-49 years) who participated (55% response rate). Of the 4 family-centered care domains, scores for treating people respectfully were highest and associated with greater clinician confidence responding to families’ psychosocial needs (effect size [β], 0.59 [95% CI, 0.46 to 0.72]; P < .001), lower depersonalization (β, 0.04 [95% CI, -0.07 to -0.01]; P = .02), and a greater sense of personal accomplishment at work (β, 0.02 [95% CI, 0.01 to 0.04]; P = 0.04). Greater interpersonal sensitivity was associated with greater confidence responding to families’ psychosocial needs (β, 0.80 [95% CI, 0.62 to 0.97]; P < .001), a greater sense of personal accomplishment at work (β, 0.03 [95% CI, 0.01 to 0.05]; P = .04), and lower use of approach-based coping, such as problem-solving (β, 0.37 [95% CI, -0.71 to -0.02]; P = .04).

CONCLUSIONS AND RELEVANCE: In this cross-sectional study, burnout and confidence responding to families’ psychosocial needs were associated with clinicians’ perceptions of family-centered care. These findings suggest that targeted interventions to address these factors may benefit clinicians and also potentially strengthen the practice of family-centered care in pediatric and congenital heart settings.

ABSTRACT

IMPORTANCE: Classifying hospitals across a wide range of pediatric capabilities, including medical, surgical, and specialty services, would improve understanding of access and outcomes.

OBJECTIVE: To develop a classification system for hospitals’ pediatric capabilities.

DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study included data from 2019 on all acute care hospitals with emergency departments in 10 US states that treated at least 1 child per day. Statistical analysis was performed from September 2023 to February 2024.

EXPOSURE: Pediatric hospital capability level, defined using latent class analysis. The latent class model parameters were the presence or absence of 26 functional capabilities, which ranged from performing laceration repairs to performing organ transplants. A simplified approach to categorization was derived and externally validated by comparing each hospital’s latent class model classification with its simplified classification using data from 3 additional states.

MAIN OUTCOMES AND MEASURES: Health care utilization and structural characteristics, including inpatient beds, pediatric intensive care unit (PICU) beds, and referral rates (proportion of patients transferred among patients unable to be discharged).

RESULTS: Using data from 1061 hospitals (716 metropolitan [67.5%]) with a median of 2934 pediatric ED encounters per year (IQR, 1367-5996), the latent class model revealed 4 pediatric levels, with a median confidence of hospital assignment to level of 100% (IQR, 99%-100%). Of 26 functional capabilities, level 1 hospitals had a median of 24 capabilities (IQR, 21-25), level 2 hospitals had a median of 13 (IQR, 11-15), level 3 hospitals had a median of 8 (IQR, 6-9), and level 4 hospitals had a median of 3 (IQR, 2-3). Pediatric level 1 hospitals had a median of 66 inpatient beds (IQR, 42-86), level 2 hospitals had a median of 16 (IQR, 9-22), level 3 hospitals had a median of 0 (IQR, 0-6), and level 4 hospitals had a median of 0 (IQR, 0-0) (P < .001). Level 1 hospitals had a median of 19 PICU beds (IQR, 10-28), level 2 hospitals had a median of 0 (IQR, 0-5), level 3 hospitals had a median of 0 (IQR, 0-0), and level 4 hospitals had a median of 0 (IQR, 0-0) (P < .001). Level 1 hospitals had a median referral rate of 1% (IQR, 1%-3%), level 2 hospitals had a median of 25% (IQR, 9%-45%), level 3 hospitals had a median of 70% (IQR, 52%-84%), and level 4 hospitals had a median of 100% (IQR, 98%-100%) (P < .001).

CONCLUSIONS AND RELEVANCE: In this cross-sectional study of hospitals from 10 US states, a system to classify hospitals’ pediatric capabilities in 4 levels was developed and was associated with structural and health care utilization characteristics. This system can be used to understand and track national pediatric acute care access and outcomes.

ABSTRACT

IMPORTANCE: Misaligned dietary rhythmicity has been associated with metabolic diseases; however, its association with mental health remains largely unexplored.

OBJECTIVE: To examine the association between dietary rhythms and the mental health condition of shift workers, specifically airline crew members.

DESIGN, SETTING, AND PARTICIPANTS: This cross-sectional study analyzed data collected from the Civil Aviation Health Cohort of China, an ongoing large-scale health survey of pilots, flight attendants, and air security officers employed by major airline companies in China. Participants aged 18 to 60 years were invited through text messages to complete a web-based survey. The data collection period was December 2022 to March 2023. Statistical analysis was performed from July 24, 2023, to April 12, 2024.

EXPOSURE: Data on timing of breakfast and dinner on workdays and rest days, daily time windows for food intake, and meal and eating jet lags were collected and calculated.

MAIN OUTCOMES AND MEASURES: Anxiety and depressive symptoms were measured using the 7-item Generalized Anxiety Disorder Assessment and the 9-item Patient Health Questionnaire. Multivariate logistic regressions were performed to evaluate the associations of anxiety and depression with meal timing, eating window time, meal jet lag (ie, delayed meals), and eating jet lag (ie, delayed eating). All models were adjusted for individual socioeconomic, demographic, and lifestyle characteristics.

RESULTS: Of the 22 617 participants (median [IQR] age, 29.1 [26.3-33.7] years; 13 712 males [60.6%]), 1755 (7.8%) had anxiety and 2768 (12.2%) had depression. After controlling for confounding factors, having dinner after 8 pm on morning-shift days was associated with increased odds of anxiety (adjusted odds ratio [AOR], 1.78; 95% CI, 1.53-2.05) and depression (AOR, 2.01; 95% CI, 1.78-2.27), compared with consuming dinner before 8 pm. Similar results were observed on night-shift days and rest days. An eating window of less than 12 hours was associated with reduced odds of anxiety (AOR, 0.84; 95% CI, 0.75-0.93) and depression (AOR, 0.81; 95% CI, 0.75-0.89) on morning-shift days; the results remained significant on rest days. Delayed dinner on morning-shift days was associated with increased odds of anxiety (AOR, 1.32; 95% CI, 1.13-1.54) and depression (AOR, 1.39; 95% CI, 1.22-1.58). On night-shift days, delayed dinner was associated with higher odds of anxiety (AOR, 1.22; 95% CI, 1.06-1.39) and depression (AOR, 1.21; 95% CI, 1.08-1.36). On morning-shift days, delayed eating rhythms were associated with higher odds of depression (AOR, 1.35; 95% CI, 1.13-1.61), whereas advanced eating rhythms were associated with lower odds of anxiety (AOR, 0.78; 95% CI, 0.70-0.87).

CONCLUSIONS AND RELEVANCE: This cross-sectional study found that meal timing, long eating window, and meal jet lags were associated with increased odds of depression and anxiety. These findings underscore the need for interventions and supportive policies that help mitigate the adverse implications of shift work and irregular working hours for the mental health of shift workers.

ABSTRACT

IMPORTANCE: Transgender youth are at an elevated risk for adverse mental health outcomes compared with their cisgender peers. Identifying opportunities for intervention is a priority.

OBJECTIVE: To estimate differences in the association between gender identity milestones and mental health outcomes among transgender youth, stratified by level of family support.

DESIGN, SETTINGS, AND PARTICIPANTS: This retrospective cohort study compares changes in mental health outcomes among transgender youth who initiate gender identity milestones compared with those who initiate the same milestones 1 year later, stratified by level of family support, using the 2015 US Transgender Survey. The analytic samples included 18 303 transgender adults aged 18 and older who had initiated at least 1 gender identity milestone between ages 4 and 18 years.

EXPOSURE: Four gender identity milestones: feeling one’s gender was different, thinking of oneself as transgender, telling another that one is transgender, and living full-time in one’s gender identity, stratified by 3 levels of family support: supportive, neutral, and adverse.

MAIN OUTCOMES: Age at first suicide attempt and at running away.

RESULTS: Study participants included 18 303 transgender adults (10 288 [56.2%] assigned female at birth; 14 777 [80.7%] White). Initiating a gender identity milestone was associated with a higher risk of suicide attempt and running away from home among transgender youth. This finding was driven by children who live in unsupportive families. For example, thinking of oneself as transgender was associated with a meaningful increase in the overall probability of attempting suicide among those in either adverse families (estimate = 1.75 percentage points; 95% CI, 0.47-3.03) or neutral families (estimate = 1.39 percentage points; 95% CI, 0.72-2.05). Among youth living with supportive families, there were no statistically significant associations between gender identity milestones and adverse mental health outcomes and 95% CIs generally ruled out any meaningful associations.

CONCLUSION: These results demonstrate that without a supportive family environment, gender identity development increases the risk of transgender youth attempting suicide or running away from home. Social services and community resources to establish supportive relationships between transgender children and their parents are essential.

ABSTRACT

BACKGROUND: Limited research has been conducted on the neural mechanisms of visuospatial attention in closed skill sports. This research aimed to delve into the unique visuospatial attention abilities of skaters and elucidate the underlying neural mechanisms.

METHODS: This cross-sectional study employed an expert-novice paradigm, applying a purely data-driven approach to analyze and compare the resting-state networks (RSNs) associated with visuospatial attention in 15 elite skaters and 15 control subjects.

RESULTS: From the 38 components identified by independent component analysis (ICA) algorithm, five RSNs were selected, including the dorsal attention network (DAN), left and right fronto-parietal network (FPN), somatomotor network (SMN) and visual network (VIS). Elite skaters exhibited heightened functional connectivity (FC) in the right angular gyrus and left precuneus within DAN, left fusiform gyrus within left FPN, right primary motor cortex within right FPN, left supplementary motor area within SMN, and right primary visual cortex within VIS compared to the control group. Conversely, skaters demonstrated diminished FC in the bilateral superior temporal gyrus within DAN and right prefrontal cortex within the right FPN.

CONCLUSIONS: Statistical results demonstrated significant differences in RSNs related to visuospatial functions in a wide range of brain regions between elite skaters and controls. We further speculate that these variances could be attributable to alterations in visuospatial abilities resulting from years of devoted skating training. The findings of this study offer novel perspectives on the neural reorganization linked to motor training, contributing to an enriched comprehension of the neuroplasticity changes inherent in prolonged engagement in motor skill development.

ABSTRACT

INTRODUCTION: Patients with type 2 diabetes (T2D) who require intensification of basal insulin therapy need treatment options that can improve their health-related quality of life (HRQoL) and translate into better outcomes. These analyses compared patient-reported outcomes (PROs) in patients with T2D receiving tirzepatide or insulin lispro.

METHODS: The randomised, open-label, multinational, phase 3b SURPASS-6 trial (NCT04537923) was conducted at 135 medical research centres and hospitals in 15 countries and compared two recommended treatment intensification strategies in people with T2D and inadequate glycaemic control on basal insulin: addition of once-weekly tirzepatide versus addition of prandial insulin lispro. Randomisation was stratified by country, baseline glycated haemoglobin level and metformin use. PROs were measured using the Short Form-36 Health Survey version 2 (SF-36v2) acute form (secondary outcome), EQ-5D-5L, Ability to Perform Physical Activities of Daily Living (APPADL) questionnaire and Impact of Weight on Self-Perceptions (IW-SP) questionnaire (tertiary/exploratory outcomes). PROs were compared for the tirzepatide-pooled dose group (5, 10 and 15 mg) and each tirzepatide dose group versus insulin lispro at 52 weeks using the modified intention-to-treat efficacy analysis set.

RESULTS: Between 19 October 2020 and 01 November 2022, 2267 people were assessed and 1428 participants with T2D were randomised. At 52 weeks, participants in the tirzepatide-pooled group had statistically significant improved scores across all SF-36v2 domains and both component summary scores compared with insulin lispro-treated participants (p < 0.05), with the largest differences observed in the general health, vitality and mental health domains. Statistically significant improved APPADL and IW-SP total scores, as well as EQ visual analogue scale and EQ-5D-5L index scores (after adjustment for baseline scores), were observed in tirzepatide-pooled participants compared with insulin lispro-treated participants.

CONCLUSIONS: In adult patients with T2D and inadequate glycaemic control with basal insulin, tirzepatide treatment was associated with greater improvements in HRQoL than prandial insulin therapy in addition to clinically significant improvements in glycaemic and body weight-related parameters.

ABSTRACT

INTRODUCTION: It remains unclear how patients with atopic dermatitis (AD) and clinicians perceive the level of patient-clinician communication and if there could be potential lapses. This cross-sectional study aims to compare perspectives between patients with AD and dermatologists regarding communication and treatment expectations in Asia.

METHODS: Moderate-to-severe patients with AD and practicing dermatologists were recruited from eight Asia-Pacific territories, including Mainland China, Hong Kong, India, Japan, Singapore, South Korea, Taiwan, and Thailand. Patients and dermatologists completed separate surveys designed to elicit their expectations regarding AD management, and their perceived level of patient-clinician communication. Patients were also asked about their treatment satisfaction and whether they prefer additional treatment beyond what was prescribed. Demographic information and responses were analyzed using descriptive statistics. The study was reviewed by the institutional review board in each territory, and all participants provided informed consent.

RESULTS: A total of 1103 patients and 271 dermatologists completed the surveys. Both patients and dermatologists were largely aligned in their top treatment goals in AD management. However, greater proportions of patients prioritized the prevention of exacerbation (78.0% versus 47.2%), minimization of treatment adverse effects (46.4% versus 9.1%), and improvement in mental health (16.0% versus 4.9%), compared with dermatologists. Although patient-clinician communication was observed to be generally good, 10.9% of patients reported dissatisfaction with communication in AD management. The majority of patients were either “very satisfied” or “satisfied” with their latest acute AD treatment, but 65.5% of patients still desired additional treatment.

CONCLUSIONS: This multinational study has provided insights on the perspectives of Asian patients and dermatologists in treatment goals, AD management, and communication. In general, both patients and dermatologists were aligned in treatment goals and there was satisfactory patient-clinician communication in most aspects. However, potential areas of improvement have been identified to further enhance patient-centered care.
