Holly Maples, Pharm.D.

Dr. Holly Maples is an Associate Professor and the Jeff & Kathy Lewis Sanders Endowed Chair in Pediatrics in the Department of Pharmacy Practice at the University of Arkansas for Medical Sciences (UAMS) and the Director for Antimicrobial Stewardship for Arkansas Children’s. Dr. Maples currently works closely with the Pediatric Infectious Diseases section to provide unification of resources to build a robust Antimicrobial Stewardship Program.

After graduating from Ohio Northern University with her Pharm.D. in 2000, Dr. Maples went on to complete her pediatric residency at Spectrum Health & DeVos Children’s Hospital in Grand Rapids Michigan. She followed that up with a fellowship in Pediatric Pharmacology cofounded by the UAMS College of Pharmacy and Arkansas Children’s that was funded by the Pediatric Pharmacology Research Unit (PPRU). During her fellowship, she spent a lot of time with the Infectious Diseases Section in HIV clinic and on ID rotation. After completing the fellowship in 2003, Dr. Maples took a faculty position with the UAMS College of Pharmacy with split funding with Arkansas Children’s where she has worked closely with pulmonology in the care of patients with cystic fibrosis, as well as ID in working with HIV and inpatient service. In 2007, in addition to antibiotic therapeutic drug monitoring, the antimicrobial stewardship program was initialized. She also developed the post-graduate training programs of pediatric ID and antimicrobial stewardship in 2007.

Dr. Maples is heavily involved in all three aspects of antimicrobial stewardship: clinical, education, and research. With the recent additions of another pharmacist and a 0.2 FTE of an ID physician to the ASP team, a restructure to the ASP program is underway as she is looking to expand services to inpatient of both Children’s campuses as well as outpatient opportunities and extension out to pediatricians across the state. Her research is around quality improvement of antimicrobial usage and engages trainees of all levels to be involved to help meet the missions of interprofessional education as well as teaching multiple disciplines about their roles as team members in antimicrobial stewardship.
