Family Medicine Residency at UPMC Horizon

Family Medicine Residency

The family medicine residency program was approved by the American Osteopathic Association (AOA) in 1988 and has recently grown to 4 residents in each year of training. The program received initial accreditation from the Accreditation Council for Graduate Medical Education (ACGME) on 04/01/2018 and initial recognition for Osteopathic Recognition effective 07/01/2019.  

This dually accredited program currently leads eligible candidates to certification by both the Osteopathic and Allopathic boards.

The mission of the program is to train residents in a small-town and rural environment to become exceptional Family Physicians and to meet the needs of the communities of Mercer and Lawrence Counties while customizing the residency experience for each resident to meet their respective career goals. We provide quality, patient-centered care across all ages and in any clinical setting. Our program features direct, one-on-one interaction with specialists as well as a strong team of experienced, passionate family medicine faculty. Our graduates serve rural to urban communities in Western Pennsylvania and throughout the United States in fields ranging from traditional primary care, all outpatient, hospitalist, ER, and urgent care. Patient care and resident education are equal partners in the mission of the residency.

Beginning in July 2018, the Family Medicine Residency Practice moved to a new, larger office behind the UPMC Horizon — Shenango Valley campus, called Shenango Valley Family Medicine. The new office allows the residents and faculty to better meet the needs of the local community by improving access to primary care and providing a comprehensive medical home.

It includes a series of inpatient rotations at UPMC Horizon (internal medicine, surgery, obstetrics, and emergency medicine), one month of inpatient pediatrics at UPMC Children’s Hospital of Pittsburgh.

Call during the intern year is dependent upon the rotation. On the inpatient medicine rotation, interns take in-house call during the daytime every other weekend. The rest of the intern class alternates for the other weekends. Weekend call outside of the inpatient rotation is 1 in 6 weekends. During the OB month, interns may take call up to once a week. Call can be assigned during inpatient pediatrics at times.

Residents also spend one half-day session, per week, in the Family Medicine Center.

The Family Medicine Practice

The continuity training experience, within the continuity of care family practice clinic, provides the resident with a training environment equivalent to that of a private practice.

The continuity training experience will develop those skills and experiences necessary to give the resident the competence and confidence to provide exceptional patient care.

Goals of Family Medicine Continuity Training

The goals of the continuity training experience are to provide:

  • A safe environment with adequate mentoring and graded levels of responsibility
  • A broad and diverse patient population
  • Exposure to office based procedures, testing, and the incorporation of osteopathic manipulative medicine
  • Comprehensive coding and billing instruction
  • Opportunities to provide care in diverse environments including nursing homes, personal care homes, and the patients’ private homes
  • Continuity of care where residents are assigned their own panel of patients from the first day of residency to develop a competent, confident, and compassionate family physician

Residents are often recruited to the local community to continue the compassionate and comprehensive care they have been taught.
