The Future of Pediatric Hospital Medicine: Challenges and Opportunities

Pediatric hospital medicine (PHM) is in the midst of an exciting period of growth. In 2016, the American Board of Medical Specialties approved the petition for PHM to become the newest pediatric subspecialty, taking PHM on a divergent path from the Focused Practice in Hospital Medicine designation established for adult hospitalists. Establishment as a subspecialty has allowed PHM to define the unique skills and qualifications that hospitalists bring to patients and the healthcare system. These skills and qualifications are delineated in the PHM core competencies and national fellowship curriculum.^1,2 In order to realize the vision of PHM to improve care for hospitalized children described by Roberts et al.,³ concerted efforts are needed to train and retain a workforce that is equipped with the skills to catalyze improvements in inpatient pediatric care. We discuss challenges and opportunities facing PHM in workforce development, sustainability of clinical work models, and interhospital collaboration.

The development of PHM as a subspecialty was driven by a number of factors.⁴ The acuity of hospitalized children has increased significantly, with a population comprised of more children with complex chronic conditions and/or technology dependence, serious complications of acute conditions, and acute mental health problems. At the same time, the medical and behavioral conditions seen by outpatient general pediatricians have become more complex and time intensive, with these practitioners less likely to work in inpatient settings. Hospitalist care has positive impacts on healthcare efficiency and value, and both parents and primary care pediatricians report high levels of satisfaction with the healthcare delivered by PHM services.⁴

A national count of the number of pediatric hospitalists is currently lacking. Conservative estimates suggest that at least 3,000 pediatric hospitalists currently practice in the United States.⁵ These hospitalists have highly varied scopes of practice and work across diverse settings—more diverse, perhaps, than any other pediatric subspecialty. Although difficult to quantify, we estimate that approximately one-third of pediatric hospitalists in the US work in community hospitals and the remainder practice at children’s hospitals.⁶ Many of the needs of hospitalized children differ across these settings, and the roles and challenges faced by hospitalists in these settings correspondingly differ. Community hospitalists frequently take active roles in newborn care and emergency department consultation, often without the support of other pediatric subspecialties.⁷ In contrast, hospitalists working at children’s hospitals more frequently care for highly complex patients, often collaborate across multiple specialties and assume nonclinical roles in quality improvement (QI), research, and medical education.

Residents graduating in July 2019 were the last cohort of residents eligible to pursue PHM subspecialty certification via the practice pathway. Accordingly, future residency graduates interested in PHM subspecialty certification will need to complete a PHM fellowship at an accredited program in the US or Canada. Since 2008, PHM fellowship directors have met yearly to collaborate and share best practices,⁸ developing the two-year fellowship curriculum that forms the basis for the American Board of Pediatrics training pathway.² The curriculum allows significant flexibility to meet diverse needs, including tailored content for fellows planning to practice in community settings, fellows planning research careers, medicine-pediatrics hospitalist careers, and those desiring increased training in QI, medical education, or leadership/administration.² In the spring of 2019, Pediatric Research in Inpatient Settings (PRIS) leadership, directors of existing PHM fellowship programs, and national academic society representatives met to develop a fellows’ research curriculum, training resources, and guidelines around scholarship expectations.⁹ This collaboration aims to accelerate the growth of high-quality clinical training and scholarship to benefit hospitalized children across many different settings.

Such collaboration is essential to address an emerging workforce challenge in PHM. Although the number of PHM fellowship positions is expected to grow in the coming years, there is currently a shortage relative to the anticipated demand. With approximately 2,800 US pediatric residents graduating annually and data indicating that 7% of graduating residents enter and remain in PHM for at least five years,^10,11 almost 200 fellowship spots may be needed each year. As of November 2019, 77 fellowship positions were available for residents graduating in 2020,¹² which is less than half of the potential demand. To address this mismatch, the PHM Fellowship Directors’ Council has led an annual training for new and potential fellowship directors, and 18 new programs are under development.¹³ However, this growth may be inadequate to meet the needs of the field. The extent to which limited PHM fellowship positions will adversely affect the pipeline of pediatricians pursuing PHM is unknown.

Efforts to support institutions in creating and expanding fellowship programs will be needed to address the potential shortage of fellowship positions. Continued guidance from the PHM Fellowship Directors’ Council in the many aspects of fellowship program development (eg, curriculum design, assessment) will be crucial in this endeavor. Furthermore, given that fellowships must support fellows to conduct scholarly work and demonstrate evidence of robust faculty scholarly activities to attain accreditation, an essential area of focus is faculty development. Considering barriers such as lack of time, mentorship, and resources, some divisions interested in starting a fellowship may find it challenging to achieve these standards.¹⁴ However, hospitalists are often engaged in areas such as QI and medical education, and there is potential to turn ongoing work into meaningful scholarship with appropriate guidance. Many of our supporting organizations (eg, Academic Pediatric Association, American Academy of Pediatrics, and Society of Hospital Medicine) provide training programs for faculty in areas such as educational scholarship, research, and QI; however, more may be needed. Leaders of PHM programs will need to be mindful and creative in accessing local, regional, and national resources to invest in faculty development.
