Ret deficiency decreases neural crest progenitor proliferation and restricts fate potential during enteric nervous system development.

The receptor tyrosine kinase RET plays a critical role in the fate specification of enteric neural crest-derived cells (ENCDCs) during enteric nervous system (ENS) development. RET loss of function (LoF) is associated with Hirschsprung disease (HSCR), which is marked by aganglionosis of the gastrointestinal (GI) tract. Although the major phenotypic consequences and the underlying transcriptional changes from Ret LoF in the developing ENS have been described, cell type- and state-specific effects are unknown. We performed single-cell RNA sequencing on an enriched population of ENCDCs from the developing GI tract of Ret null heterozygous and homozygous mice at embryonic day (E)12.5 and E14.5. We demonstrate four significant findings: 1) Ret-expressing ENCDCs are a heterogeneous population comprising ENS progenitors as well as glial- and neuronal-committed cells; 2) neurons committed to a predominantly inhibitory motor neuron developmental trajectory are not produced under Ret LoF, leaving behind a mostly excitatory motor neuron developmental program; 3) expression patterns of HSCR-associated and Ret gene regulatory network genes are impacted by Ret LoF; and 4) Ret deficiency leads to precocious differentiation and reduction in the number of proliferating ENS precursors. Our results support a model in which Ret contributes to multiple distinct cellular phenotypes during development of the ENS, including the specification of inhibitory neuron subtypes, cell cycle dynamics of ENS progenitors, and the developmental timing of neuronal and glial commitment.

Current Issues Affecting the Practice of Pediatric Orthopaedic Surgeons: Results of the 2014 Workforce Survey of American Academy of Pediatrics Section on Orthopaedics.

INTRODUCTION: The opinions of the pediatric orthopaedic workforce are shaped by market forces, regulatory processes, and local experience. The purpose of this report is to summarize the findings of the recent Workforce Survey of the American Academy of Pediatrics (AAP) Section on Orthopaedics (SOOr). This submission has been reviewed and approved by the Board of Directors of the Pediatric Orthopaedic Society of North America (POSNA). METHODS: In 2014, the AAP generated a survey to assess perceptions of pediatric orthopaedic surgeons about current issues that affect practice. The survey was sent to 856 POSNA and 141 AAP-SOOr members. Responses were topically organized to report current workforce composition, practice patterns, and perceptions about electronic medical records (EMRs). RESULTS: Responses were collected from August to December, 2014, from 496 (50%) survey recipients including 83 of 141 (59%) AAP-SOOr members and 413 of 856 (48%) POSNA members. Analyses were restricted to the 397 respondents who reported that they are currently practicing pediatric orthopaedics. Nearly all of these (390/391, 100%) indicated that they provide direct patient care and work an average of 60 hours per week. Many (105/378, 28%) indicated that they would soon limit their practice or retire. A majority (299/394, 76%) indicated that they face competition in their geographic area, predominantly due to pediatric orthopaedic subspecialists (269/299, 90%). Major business changes had recently occurred or were anticipated by 21% of participants. Respondents reported that use of EMR makes them less efficient (252/397, 63%) and interferes with the patient-physician relationship (172/397, 43%). DISCUSSION: This workforce survey suggests that pediatric orthopaedic surgeons are concerned with challenges of competition despite concurrent increasing volume and complexity of referrals. External processes such as EMR changes are perceived to negatively impact practice efficiency and satisfaction.

Factors Influencing Pediatrician Retirement: A Survey of American Academy of Pediatrics Chapter Members.

OBJECTIVE: To assess the factors that may influence physicians' desire to retire through an analysis of data collected through the American Academy of Pediatrics (AAP) State Pediatrician Workforce Survey. STUDY DESIGN: An electronic survey was sent to retired and nonretired US pediatricians who held AAP membership. The respondents were asked about the importance of 12 factors that would influence or had influenced their decision to retire. The physicians who were not yet retired also were asked: "If you could afford to today, would you retire from medicine?" RESULTS: The survey was completed by 8867 pediatricians. Among the nonretired respondents, 27% reported that they would retire today if it were affordable. Increasing regulation of medicine, decreasing clinical autonomy, and insufficient reimbursement were rated as very important factors by >50% of these pediatricians. Among retired pediatricians, 26.9% identified the effort to keep up with clinical advances and changes in practice as a very important factor in their decision to retire. Younger physicians were significantly more likely to rate maintenance of certification requirements, insufficient reimbursement, lack of professional satisfaction, and family responsibilities as very important factors. Rural pediatricians were more interested in retiring than those working in academic settings. There were no sex differences. CONCLUSIONS: Twenty-seven percent of pediatricians in practice today would retire today if it were affordable. Identifying and addressing the important factors that influence a pediatrician's desire to retire can potentially reduce the retirement rate of pediatricians and thus increase access to care for children.

The US pediatric nephrology workforce: a report commissioned by the American Academy of Pediatrics.

The US pediatric nephrology workforce is poorly characterized. This report describes clinical and nonclinical activities, motivations and disincentives to a career in pediatric nephrology, future workforce needs, trainee recruitment, and possible explanations for personnel shortages. An e-mail survey was sent in 2013 to all identified US-trained or -practicing pediatric nephrologists. Of 504 respondents, 51% are men, 66% are US graduates, and 73% work in an academic setting. About 20% of trained pediatric nephrologists no longer practice pediatric nephrology. Among the 384 respondents practicing pediatric nephrology full or part-time in the United States, the mean work week was 56.1±14.3 hours, with time divided between patient care (59%), administration (13%), teaching (10%), clinical research (9%), basic research (6%), and other medical activities (3%). Most (>85%) care for dialysis and transplantation patients. The median number of weeks annually on call is 16, and 29% work with one or no partner. One-third of US pediatric nephrologists (n=126) plan to reduce or stop clinical nephrology practice in the next 5 years, and 53% plan to fully or partially retire. Almost half the division chiefs (47%) report inadequate physician staffing. Ongoing efforts to monitor and address pediatric nephrology workforce issues are needed.

Practice Patterns in Pediatric Critical Care Medicine: Results of a Workforce Survey.

OBJECTIVE: To obtain current data on practice patterns of the U.S. pediatric critical care medicine workforce. DATA SOURCES: Membership of the American Academy of Pediatrics Section on Critical Care and individuals certified by the American Board of Pediatrics in pediatric critical care medicine. STUDY SELECTION: All active members of the American Academy of Pediatrics Section on Critical Care, and nonduplicative individuals certified by the American Board of Pediatrics in pediatric critical care medicine, were classified as eligible to participate in this electronically administered workforce survey. DATA EXTRACTION: Data were extracted by a doctorate-level research professional. Extracted data included demographic information, work environment, number of hours worked, training, clinical responsibilities, work satisfaction and burnout, and plans to leave the practice of pediatric critical care medicine. DATA SYNTHESIS: Of 1,857 individuals contacted, 923 completed the survey (49.7%). The majority of respondents were white, male, non-Hispanic, university-employed, and taught residents. Respondents who worked full time were on clinical intensive care service for a median of 15 wk/yr and responsible for a median of 13 ICU beds, working a median of 60 hr/wk. Total night call responsibility was a median of 60 nights/yr; about half of respondents indicated night call was in-hospital. Fewer than half were engaged in basic science or clinical research. Compared with earlier data, there was minimal change in work hours and proportion of time devoted to research, but there was an increase in the proportion of female pediatric critical care medicine physicians. CONCLUSIONS: These data provide a description of the typical intensivist and a snapshot of the current pediatric critical care medicine workforce, which may be experiencing a mild-to-moderate undersupply. The results are useful for assessing the current workforce and valuable for future planning.

Transition Planning for Youth With Special Health Care Needs (YSHCN) in Illinois Schools.

"Transition Planning for Youth with Special Health Care Needs (YSHCN)" chronicles the research and work completed by agencies in Illinois to provide examples of best practice in transition planning. Increasing numbers of YSHCN survive into adulthood creating a need for focus on the transition to adult life for these young people, including meeting health care needs. As a part of the Transitions project, the Illinois Chapter of the American Academy of Pediatrics and the University of Illinois at Chicago Division of Specialized Care for Children surveyed Illinois public high schools to identify transition planning efforts, staff training needs and used those results to develop and implement training. A natural way to organize health services is by integration with school transition services. The credentialed school nurse would be the ideal person to contribute to the development of the health care transition plans based on the student's heath care provider's medical management plan.

Gender and work-life balance: Results of a national survey of pediatric hospitalists.

In medicine, difficulty integrating work and home can lead to decreased job satisfaction, diminished well-being, and increased turnover. Understanding the experience of pediatric hospitalists can provide insights into building a stable, long-term workforce. We aim to examine gender differences in work-life balance and parental leave for physicians practicing Pediatric Hospital Medicine. METHODS: This was a cross-sectional survey study of 1096 pediatric hospitalists. Responses were collected via an online survey platform and summarized using descriptive statistics, including frequency distributions and measures of central tendency. A multivariable logistic regression was used to examine associated variables and work-life balance satisfaction. We analyzed free responses on parental leave to provide nuance to quantitative survey data. RESULTS: Five hundred and sixty-five respondents (52% response rate) completed the survey with 71% women. 343 (62%) prioritize work-life balance in career decision-making. Women report taking on more household responsibilities than their partners (41.4% vs. 8.4%; p < .001) including a larger percentage of caregiving and domestic tasks. Female gender and performing <50% caregiving were associated with decreased work-life balance satisfaction; performing <50% domestic tasks increased satisfaction. Median parental leaves were 4 weeks, with men taking significantly shorter leaves (3.5 vs. 6 weeks; p < .001) and more "paid back" time off. CONCLUSION: Work-life balance is an important factor in career decisions for men and women. Women perceive carrying a larger load at home. Qualitative results suggest that parental leave may be inadequate in length and salary support for men and women. This study adds insights into work-life integration in PHM.

Association Between Gender and Salary Among Pediatric Hospital Medicine Physicians.

OBJECTIVES: Gender-based disparities in salary exist in multiple fields of medicine. However, there is limited data examining gender inequities in salary in pediatric hospital medicine (PHM). Our primary objective was to assess whether gender-based salary differences exist in PHM. The secondary objective was to assess if, among women, the differences in salary varied on the basis of leadership positions or self-identified race and ethnicity. METHODS: We conducted a survey-based, cross-sectional study of pediatric hospitalists in December 2021. Our primary outcomes were base and total salary, adjusted for the reported number of average weekly work hours. We performed subanalyses by presence of a leadership position, as well as race. We used a weighted t test using inverse probability weighting to compare the outcomes between genders. RESULTS: A total of 559 eligible people responded to our survey (51.0%). After propensity score weighting, women's mean base salary was 87.7% of men's base (95% confidence interval [CI] 79.8%-96.4%, P < .01), and women's total salary was 85.6% of men's total (95% CI 73.2%-100.0%, P = .05) salary. On subgroup analysis of respondents with a leadership position, women's total salary was 80.6% of men's total salary (95% CI 68.7%-94.4%, P < .01). Although women who identified as white had base salaries that were 86.6% of white men's base salary (95% CI 78.5%-95.5%, P < .01), there was no gender-based difference noted between respondents that identified as nonwhite (88.4% [69.9%-111.7%] for base salary, 80.3% [57.2% to 112.7%]). CONCLUSIONS: Gender-based discrepancies in salary exists in PHM, which were increased among those with leadership roles. Continued work and advocacy are required to achieve salary equity within PHM.

Cardiac muscle-restricted partial loss of Nos1ap expression has limited but significant impact on electrocardiographic features.

Genome-wide association studies have identified sequence polymorphisms in a functional enhancer of the NOS1AP gene as the most common genetic regulator of QT interval and human cardiac NOS1AP gene expression in the general population. Functional studies based on in vitro overexpression in murine cardiomyocytes and ex vivo knockdown in zebrafish embryonic hearts, by us and others, have also demonstrated that NOS1AP expression levels can alter cellular electrophysiology. Here, to explore the role of NOS1AP in cardiac electrophysiology at an organismal level, we generated and characterized constitutive and heart muscle-restricted Nos1ap knockout mice to assess whether NOS1AP disruption alters the QT interval in vivo. Constitutive loss of Nos1ap led to genetic background-dependent variable lethality at or right before birth. Heart muscle-restricted Nos1ap knockout, generated using cardiac-specific alpha-myosin heavy chain promoter-driven tamoxifen-inducible Cre, resulted in tissue-level Nos1ap expression reduced by half. This partial loss of expression had no detectable effect on the QT interval or other electrocardiographic and echocardiographic parameters, except for a small but significant reduction in the QRS interval. Given that challenges associated with defining the end of the T wave on murine electrocardiogram can limit identification of subtle effects on the QT interval and that common noncoding NOS1AP variants are also associated with the QRS interval, our findings support the role of NOS1AP in regulation of the cardiac electrical cycle.

Obesity care strategies in primary care practices.

We evaluated pediatric obesity clinics for internal referrals developed at 5 primary care offices. Clinics developed site-specific strategies: 1 group approach and 4 clinics providing individualized care only. Clinicians reported patient/family motivation as an important referral consideration and compliance as the greatest challenge and perceive clinics to have provided some help.

The 2021 Pediatric Hospital Medicine Workforce: Results of a National Survey of Program Leaders.

OBJECTIVE: Pediatric Hospital Medicine (PHM) is a young subspecialty with practice models that continue to evolve. To inform program and workforce planning, it is essential to understand the current state. This study sought to delineate current work models for PHM. METHODS: In the spring of 2021, we conducted a survey-based cohort study of individuals identifying as PHM program leaders. Individuals were invited based on membership in the 3 PHM sponsoring societies. Additional respondents were recruited through society listservs. RESULTS: One hundred ninety-eight program leaders responded to the program model survey. One-half covered only community sites, 21.2% covered only university sites, and 21.2% covered both university and community sites. Programs provided a diverse set of services, with community sites covering more services, including newborn nurseries, emergency department consultation, and delivery room care. Median total hours for 1.0 clinical full time equivalent were 1849 across all sites, 1800 at university-only sites, and 1900 at community-only sites. Inpatient floor patient caps, when present, were higher for resident covered versus noncovered teams (16 vs 13). Similarly, back-up activation was higher for resident-covered teams (15-16) than noncovered teams (12-13.5). CONCLUSIONS: Current data on clinical work hours for pediatric hospitalists are consistent with recent, smaller studies, suggesting that the current national median for a 1.0 FTE clinical position at university-based sites is 1800 annual hours. Community hospitalists often work more clinical hours than university sites and more commonly provide a broader range of service lines. More studies are needed to explore the differences between community and university site work models.

A national survey of 'inactive' physicians in the United States of America: enticements to reentry.

BACKGROUND: Physicians leaving and reentering clinical practice can have significant medical workforce implications. We surveyed inactive physicians younger than typical retirement age to determine their reasons for clinical inactivity and what barriers, real or perceived, there were to reentry into the medical workforce. METHODS: A random sample of 4975 inactive physicians aged under 65 years was drawn from the Physician Masterfile of the American Medical Association in 2008. Physicians were mailed a survey about activity in medicine and perceived barriers to reentry. Chi-square statistics were used for significance tests of the association between categorical variables and t-tests were used to test differences between means. RESULTS: Our adjusted response rate was 36.1%. Respondents were fully retired (37.5%), not currently active in medicine (43.0%) or now active (reentered, 19.4%). Nearly half (49.5%) were in or had practiced primary care. Personal health was the top reason for leaving for fully retired physicians (37.8%) or those not currently active in medicine (37.8%) and the second highest reason for physicians who had reentered (28.8%). For reentered (47.8%) and inactive (51.5%) physicians, the primary reason for returning or considering returning to practice was the availability of part-time work or flexible scheduling. Retired and currently inactive physicians used similar strategies to explore reentry, and 83% of both groups thought it would be difficult; among those who had reentered practice, 35.9% reported it was difficult to reenter. Retraining was uncommon for this group (37.5%). CONCLUSION: Availability of part-time work and flexible scheduling have a strong influence on decisions to leave or reenter clinical practice. Lack of retraining before reentry raises questions about patient safety and the clinical competence of reentered physicians.

Multiple, independent, common variants at RET, SEMA3 and NRG1 gut enhancers specify Hirschsprung disease risk in European ancestry subjects.

PURPOSE: Hirschsprung disease (HSCR) is a developmental disorder of the enteric nervous system (ENS) characterized by congenital aganglionosis arising from coding variants in ENS genes causing partial or total loss-of-function. Low-penetrance, common, noncoding variants at RET, SEMA3 and NRG1 loci are also associated with HSCR, with small-to-moderate loss of gene expression mediated through sequence variants in cis-regulatory elements (CRE) as another causal mechanism. Since these latter variants are common, many individuals carry multiple risk variants. However, the extent and combinatorial effects of all putative CRE variants within and across these loci on HSCR is unknown. METHODS: Using 583 HSCR subjects, one of the largest samples of European ancestry studied, and genotyping 56 tag variants, we evaluated association of all common variants overlapping putative gut CREs and fine-mapped causal variants at RET, SEMA3 and NRG1. RESULTS: We demonstrate that 28 and 8 tag variants, several of which are genetically independent, overlap putative-enhancers at the RET and SEMA3 loci, respectively, as well as two fine-mapped tag variants at the NRG1 locus, are significantly associated with HSCR. Importantly, disease risk increases with increasing numbers of risk alleles from multiple variants within and across these loci, varying >25-fold across individuals. CONCLUSION: This increasing allele number-dependent risk, we hypothesize, arises from HSCR-relevant ENS cells sensing the reduced gene expression at multiple ENS genes since their developmental effects are integrated through gene regulatory networks.

Developmental-Behavioral Pediatrics 13 Years After the First Board Certification: Evolving Subspecialty.

OBJECTIVE: To examine and define the evolving subspecialty of developmental-behavioral pediatrics (DBP) by analyzing workforce surveys presubspecialty and postsubspecialty certification. METHODS: In 2015, an electronic workforce survey was sent to the members of the American Academy of Pediatrics Section on DBP and Council on Children with Disabilities and the Society for DBP. Answers from the 1998 survey for respondents with subspecialty fellowship training were compared. RESULTS: Compared with the 1998 group of 265 DBPs, the 368 DBPs in the 2015 group were older, more female, and more diverse. In both groups, ≥80% evaluated and treated autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and developmental delays, but significantly (p < 0.001) fewer cared for children with physical disabilities (e.g., cerebral palsy [58% to 41%], multihandicapped [53% to 39%], neonatal follow-up [47% to 31%], and spina bifida [26% to 13%]) and other disorders (e.g., failure to thrive and obesity/eating disorders [27% to 15%]). Time for new patient and return visits remained the same (1.5 hours and 0.7 hours). Pediatric generalists and family practice physicians initiated most referrals; fewer 2015 DBPs (p < 0.001) reported school districts (83% to 70%) and more reported pediatric subspecialty (57% to 77%; p < 0.001) referrals. Acknowledgment of the need for more community DBP specialists increased from 66% to 80% (p < 0.001). CONCLUSION: Survey data indicated that the workforce is aging and changing. ADHD, ASD, and developmental delays are solidifying as the defining clinical focus of DBP. Current trends can identify training needs, facilitate recruitment, and advocate for system change to support the DBP workforce to respond to the great need.

The Role of DNA Methylation in Transcriptional Regulation of Pro-Nociceptive Genes in Rat Trigeminal Ganglia.

Epigenetic modulation by DNA methylation is associated with aberrant gene expression in sensory neurons, which consequently leads to pathological pain responses. In this study, we sought to investigate whether peripheral inflammation alters global DNA methylation in trigeminal ganglia (TG) and results in abnormal expression of pro-nociceptive genes. Our results show that peripheral inflammation remotely reduced the level of global DNA methylation in rat TG with a concurrent reduction in DNMT1 and DNMT3a expression. Using unbiased steps, we selected the following pro-nociceptive candidate genes that are potentially regulated by DNA methylation: TRPV1, TRPA1, P2X3, and PIEZO2. Inhibition of DNMT with 5-Aza-dC in dissociated TG cells produced dose-dependent upregulation of TRPV1, TRPA1, and P2X3. Systemic treatment of animals with 5-Aza-dC significantly increased the expression of TRPV1, TRPA1, and PIEZO2 in TG. Furthermore, the overexpression of DNMT3a, as delivered by a lentiviral vector, significantly downregulated TRPV1 and PIEZO2 expression and also reliably decreased TRPA1 and P2X3 transcripts. MeDIP revealed that this overexpression also significantly enhanced methylation of CGIs associated with TRPV1 and TRPA1. In addition, bisulfite sequencing data indicated that the CGI associated with TRPA1 was methylated in a pattern catalyzed by DNMT3a. Taken together, our results show that all 4 pro-nociceptive genes are subject to epigenetic modulation via DNA methylation, likely via DNMT3a under inflammatory conditions. These findings provide the first evidence for the functional importance of DNA methylation as an epigenetic factor in the transcription of pro-nociceptive genes in TG that are implicated in pathological orofacial pain responses.

US pediatric pulmonology workforce.

AIM: Children with respiratory conditions benefit from care provided by pediatric pulmonologists. As these physicians are a small portion of the overall pediatric workforce, it is necessary to understand the practices and career plans of these specialists. METHODS: An internet survey was developed by the American Academy of Pediatrics Division of Workforce and Medical Education Policy and sent to members of the American Academy of Pediatrics and American College of Chest Physicians who identified as pediatric pulmonary physicians. RESULTS: Responses were received from 485 physicians and were compared to the results of a similar survey done in 1997. Of those completing the survey, 63% were male and 37% female, with increased number of females since the earlier poll. The average calculated age was 56 years. They worked 54 h per week, down from 59 h in the prior survey. Pediatric pulmonologists are overwhelmingly clinicians (92%) with major responsibilities for administration (79%), teaching (78%), and research. Basic science research was rarely reported (7%). Pediatric pulmonologists felt that referrals had become more complicated in the recent past. Nearly all planned to maintain Pediatric Pulmonology Sub-board certification, though one third planned to cut back on clinical workload in the next decade. Many were concerned that the number needed in the profession in a decade would be inadequate with significant concerns about funding for those positions. CONCLUSION: Overall, these results reflect the current state of the workforce and the need to monitor the supply of practitioners in the future.

The Community Access to Child Health (CATCH) Program: A 25-Year Retrospective.

For 25 years, the American Academy of Pediatrics (AAP) Community Access to Child Health (CATCH) program has supported pediatricians in collaborating within their communities to advance the health of all children. CATCH grants support pediatric residents and pediatricians in planning or implementing community-based child health initiatives. The CATCH program has provided almost 10 million dollars through 842 planning, 585 resident, and 305 implementation grants to >1700 pediatricians. Urban, rural, suburban, and tribal communities in every state as well as the District of Columbia and Puerto Rico have benefited from CATCH-funded projects. Collaborations with community partners such as schools, homeless shelters, and mental health centers have led to programs serving children and families, especially those living in poverty and in minority groups. The most recent program data reveal that 87.5% of the projects are operating 2 years after funding. Many CATCH projects have not only sustained themselves but have grown into larger programs with funding from other sources. CATCH has influenced pediatricians' careers by providing important skills, networking opportunities, career legitimacy, mentoring opportunities, and increased engagement with the AAP. More than 350 pediatricians have served the AAP as CATCH facilitators, the network of physicians that provides technical assistance to applicants and reviews grant applications. Responding to changing trends, CATCH leaders have looked at other funding models and recently launched the CATCH-On initiative. CATCH-On creates and provides templates from successful CATCH projects to busy pediatricians who can then implement the project in their communities with minimal funding.

Profile of the Pediatric Infectious Disease Workforce in 2015.

BACKGROUND: Almost 20 years have elapsed since the last workforce survey of pediatric infectious disease (PID) subspecialists was conducted in 1997-1998. The American Academy of Pediatrics Section on Infectious Diseases in collaboration with the Pediatric Infectious Diseases Society sought to assess the status of the current PID workforce. METHODS: A Web-based survey conducted in 2015 collected data on demographics, practice patterns, and job satisfaction among the PID workforce, and identified factors related to job placement among recent fellowship graduates. RESULTS: Of 946 respondents (48% response rate), 50% were female. The average age was 51 years (range, 29-88 years); 63% were employed by an academic center/hospital, and 85% provided direct patient care; and 18% were not current PID practitioners. Of the 138 (21%) respondents who had completed a PID fellowship within the previous 5 years, 83% applied for <5 PID positions; 43% reported that their first position was created specifically for them; 47% had 1 job offer, and 41% had 2 or 3 job offers; 82% were employed within 6 months; and 74% remained at the institution of their first job. Respondents who were practicing PID full-time or part-time (n = 778) indicated desiring more focused training in immunodeficiencies (31%), transplant-related care (31%), and travel/tropical medicine (28%). Overall, 70% of the respondents would "definitely" or "probably" choose PID again. CONCLUSIONS: Most respondents were satisfied with their career choice in PID. Most of the recent fellowship graduates were employed within 6 months after training. We identified potential areas in which the PID community can focus efforts to maintain the pipeline and improve satisfaction among its physicians.

The Role of Hospital Design in Reducing Anxiety for Pediatric Patients.

OBJECTIVES: To study the impact of hospital design on patient and family experiences during and after hospitalization. BACKGROUND: Hospitalization can be psychologically traumatic for children. Few research studies have studied the role of the design of the hospital environment in mitigating that traumatic experience. METHODS: The study employs a two-group posttest and follow-up design to compare the impact of hospitalization on child anxiety and parent stress. It compares the experiences of children (ages 3-17) hospitalized at a new facility designed to support child-centered care and with family-friendly features with an older facility that did not have these features. The new facility was a replacement of the old one, so that many challenges to comparison are addressed. RESULTS: Controlling for the facts of hospitalization, patient demographics, and the child's typical anxiety level, children in the new facility experienced less anxiety than in the old facility. The study does not provide evidence that the hospital design reduced the psychological sequelae of hospitalization. Parents and children found different features of the hospital to be restorative. CONCLUSIONS: The study supports the use of Ulrich's theory of supportive design to children's healthcare environments, though what is experienced as supportive design will vary by the developmental stage of the child.

Workforce Trends and Analysis of Selected Pediatric Subspecialties in the United States.

OBJECTIVE: To update pediatric subspecialty workforce data to support evidence-based legislation and public policy decisions by replicating the American Academy of Pediatrics' 1998 Future of Pediatric Education (FOPE II) workforce survey. METHODS: A descriptive and comparative analysis of survey responses from 9950 US pediatric subspecialists who completed an electronic survey. RESULTS: Pediatric subspecialists are working fewer hours and spending less of their time in direct patient care than they did in 1998 but the mean hours worked differs significantly according to subspecialty. Most subspecialists continue to be board-certified, white, non-Hispanic men, although the percentage who are women and from minority groups has increased. The proportion of subspecialists practicing in an academic medical center has increased since 1998. Thirty percent of pediatric subspecialists reported appointment wait times of >2 weeks and pediatric subspecialists in developmental pediatrics, endocrinology, and neurology identified much longer wait times than other subspecialists. CONCLUSION: The demographic and practice characteristics of pediatric subspecialists have changed since the FOPE II survey and access to subspecialty care in a family's community remains a challenge. However, pediatric subspecialties are not monolithic and solutions to workforce shortages will need to take into account these differences to improve access to subspecialty care.
