Research Interest
Dr. Arbulu is interested in evaluating common opportunities for optimizing antibiotic use encountered in primary care and hospital medicine. Current projects include:
- Implementation of a primary care/infectious diseases outpatient protocol to manage inappropriately labeled penicillin allergies.
- Effectiveness of oral antibiotics and long-acting glycopeptides for osteomyelitis associated with diabetic foot infections.
- Appropriate choice and duration of antibiotics for prophylaxis after grade 3 open fractures.
Clinical Interest
Dr. Arbulu’s interest and current practice is in general infectious diseases and antimicrobial stewardship.

Prior to joining University of Pittsburgh in 2018, Dr. Arbulu conceived and initiated the Antimicrobial Stewardship Program (ASP) at Mary Greeley Medical Center in Ames, Iowa. At the time of its inception in 2015, a program of this nature was lacking throughout Central Iowa outside of Des Moines. By the third quarter into the ASP, the Standardized Index Ratio of hospital-onset Clostridium difficile-associated diarrhea decreased by 58.1% from baseline. By the end of the ASP's second year, the hospital achieved a 21.6% cumulative reduction in the antimicrobial cost per patient-day. Dr. Arbulu later led the expansion of the ASP to nursing homes and to a critical care access hospital within the network. In 2018, the Iowa Healthcare Collaborative recognized Mary Greeley Hospital’s ASP with the 2018 Quality and Safety Award, quoting its innovative nature in the Region.
Educational Interest
Dr. Arbulu oversees the Infectious Diseases curriculum for the Internal Medicine Residency Program at UPMC Mercy. He also conducts educational activities directed to Podiatry and Pharmacy Residents at UPMC Mercy.
Dr. Arbulu is currently conducting an initiative to optimize noon conferences at the Internal Medicine Program at UPMC Mercy and providing feedback to Faculty on their lectures.
