Family Medicine Residency Overview

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.

First Year

The first year provides incoming residents with solid introduction to the breadth and diversity of family medicine. It includes a series of inpatient rotations at UPMC Horizon (internal medicine, surgery, obstetrics, and emergency medicine), one month of inpatient pediatrics at Children’s Hospital of Pittsburgh.

Call during the intern year is dependent upon the rotation. On inpatient medicine, interns take in-house call during the daytime every other weekend. In the last six months of the year, you will be asked to cover one weekend in eight on the inpatient service. During the OB month, interns may take call up to once a week. All other rotations do not have assigned call.

Residents also spend one half-day session, per week, at our American Osteopathic Association (AOA)-approved Continuity of Care Family Medicine Clinic.

Second and Third Years

The second and third-year curriculum offers a broader array of experiences, along with the required rotations by the AOA, in order to achieve a greater educational experience in medicine and surgery.

Second year residents spend 3 half-day sessions, on average, per week in the office and third year residents spend 3-4 half-day sessions, depending upon the rotation.

Call in the second and third years is dependent upon the rotation. Senior residents will cover every other weekend, daytime only, while they are on the inpatient medicine rotation. Daytime weekend coverage will be one in eight when not on the rotation.

Senior residents will also take in-home call averaging 1:8 for the practice and for obstetric continuity patients.

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.
