    Multiple professional societies have emphasized the importance of professional development for physicians. This qualitative study aimed to explore pediatric hospitalists' perceptions of professional development needs and to refine a framework for professional development in pediatric hospital medicine (PHM). We conducted four focus groups in April to May 2019 with 19 pediatric hospitalists at six clinical sites within a single institution. Participants identified key components of professional development including skill development, personal growth, career satisfaction, and individualization. Hospitalists agreed upon 8 domains of professional development: clinical excellence, advocacy, global health, health care administration, informatics, medical education, quality improvement, and research. They also identified missing the mentorship necessary to change their passions into career advancement, highlighted barriers and facilitators, and noted that an alignment in personally meaningful projects to what is meaningful to the institution was in everyone's best interests. Faculty programs should build infrastructure to aid pediatric hospitalists in achieving their career goals.

  • Faculty Development in Academic Hospital Medicine: a Scoping Review. Journal of general internal medicine Misky, G. J., Sharpe, B., Weaver, A. C., Niranjan-Azadi, A., Gupta, A., Rennke, S., Ludwin, S., Piper, C., Mlis, Sun, V. K., Brotman, D. J., Frank, M. 2023


    This scoping review sought to identify and describe the state of academic faculty development programs in hospital medicine and other specialties. We reviewed faculty development content, structure, metrics of success including facilitators, barriers, and sustainability to create a framework and inform hospital medicine leadership and faculty development initiatives. We completed a systematic search of peer-reviewed literature and searched Ovid MEDLINE ALL (1946 to June 17, 2021) and Embase (via Elsevier, 1947 to June 17, 2021). Twenty-two studies were included in the final review, with wide heterogeneity in program design, program description, outcomes, and study design. Program design included a combination of didactics, workshops, and community or networking events; half of the studies included mentorship or coaching for faculty. Thirteen studies included program description and institutional experience without reported outcomes while eight studies included quantitative analysis and mixed methods results. Barriers to program success included limited time and support for faculty attendance, conflicting clinical commitments, and lack of mentor availability. Facilitators included allotted funding and time for faculty participation, formal mentoring and coaching opportunities, and a structured curriculum with focused skill development supporting faculty priorities. We identified heterogeneous historical studies addressing faculty development across highly variable program design, intervention, faculty targeted, and outcomes assessed. Common themes emerged, including the need for program structure and support, aligning areas of skill development with faculty values, and longitudinal mentoring/coaching. Programs require dedicated program leadership, support for faculty time and participation, curricula focused on skills development, and mentoring and sponsorship.

  • How safe is your neighborhood? Perceived neighborhood safety and functional decline in older adults. Journal of general internal medicine Sun, V. K., Stijacic Cenzer, I., Kao, H., Ahalt, C., Williams, B. A. 2012; 27 (5): 541-7


    Neighborhood characteristics are associated with health and the perception of safety is particularly important to exercise and health among older adults. Little is known about the relationship between perception of neighborhood safety and functional decline in older adults.To determine the relationship between perceived neighborhood safety and functional decline in older adults.Longitudinal, community-based.18,043 persons, 50 years or older, who participated in the 1998 and 2008 Health and Retirement Study.The primary outcome was 10-year functional decline (new difficulty or dependence in any Activity of Daily Living, new mobility difficulty, and/or death). The primary predictor was perceived neighborhood safety categorized into three groups: "very safe", "moderately safe", and "unsafe." We evaluated the association between perceived neighborhood safety and 10-year functional decline using a modified Poisson regression to generate unadjusted and adjusted relative risks (ARR).At baseline 11,742 (68.0%) participants perceived their neighborhood to be very safe, 4,477 (23.3%) moderately safe, and 1,824 (8.7%) unsafe. Over 10 years, 10,338 (53.9%) participants experienced functional decline, including 6,266 (50.2%) who had perceived their neighborhood to be very safe, 2,839 (61.2%) moderately safe, and 1,233 (63.6%) unsafe, P < 0.001. For the 11,496 (63.3%) of participants who were functionally independent at baseline, perceived neighborhood safety was associated with 10-year functional decline (moderately safe ARR 1.15 95% CI 1.09-1.20; unsafe ARR 1.21 95% CI: 1.03-1.31 compared to very safe group). The relationship between perceived neighborhood safety and 10-year functional decline was not statistically significant for participants who had baseline functional impairment.Asking older adults about their perceived neighborhood safety may provide important information about their risk of future functional decline. These findings also suggest that future studies might focus on assessing whether interventions that promote physical activity while addressing safety concerns help reduce functional decline in older adults.
