Mercy Medical Center Merced

Together for a healthier future.

The Merced Family Medicine Residency Program trains resident physicians to provide comprehensive, continuous, and compassionate care to patients, particularly in rural and underserved environments. As part of Dignity Health, we are a member of CommonSpirit Health's national network of more than 2,200 care sites across 24 states. That broad perspective supports our local commitment to community-based training, health equity and compassionate care. Mercy Medical Center Merced is a 186-bed, Joint Commission accredited hospital, serving as a regional medical center for an agricultural area of central California, with our core outpatient experience taking place in the licensed Rural Health Clinic, Family Care Clinic. Residents gain a rich variety of experiences in both inpatient and outpatient settings, fostering independent learning and strong faculty support. Upon graduation, residents are prepared to be outstanding, full-spectrum, independent Family Physicians capable of practicing in diverse environments, including rural and underserved areas.

Name, Title

Curriculum

Our curriculum provides a broad and extensive inpatient and outpatient experience, helping residents achieve holistic, compassionate, and culturally-aware care for diverse patients across society. A didactic conference is held each Tuesday afternoon, and several options are available for both inpatient and outpatient electives.

PGY-1:
Foundational training

Foundational training includes twelve weeks on the Inpatient Medicine Service, eight to nine weeks on the busy obstetric and gynecology service, and rotations in surgery subspecialties like ENT and Urology. Residents spend one to three half-days a week in the Family Care Clinic.

PGY-2:
Expanded clinical responsibility

Expanded clinical responsibility includes six to eight additional weeks on the medicine rotation supervising first-year residents, two weeks in the NICU, two weeks in an emergency room at Valley Children's Hospital, a four-week geriatrics rotation, and continuous experience in the emergency room. Residents spend three to four half-days a week in the Family Care Clinic.

PGY-3:
Independent practice preparation

Independent practice preparation includes four weeks on the medicine service supervising and teaching first-year residents, continuous experience in the emergency room, and the majority of elective time, allowing residents to select clinical areas of concentration to adjust training for future practice settings. Residents spend four to five half-days a week in the Family Care Clinic.

Additional Curriculum Experiences

Didactics and protected education time

A didactic conference is held each Tuesday afternoon. Residents also participate in a Behavioral Science didactic session every Wednesday afternoon, which is a longitudinal rotation over the course of the residency program.

Procedural training

Residents acquire experience in EKG interpretation and gain expertise in procedures such as lesion removal, joint injections, and placement of IUD and Nexplanon. The Family Care Clinic also offers a skin care clinic, vasectomy, and circumcision procedures.

Scholarly activity and quality improvement

We encourage residents to become independent learners, developing a habit of learning and inquisitiveness through daily presentations, required senior resident presentations, and promoting the searching of medical literature. Quality improvement is a focus for the Associate Program Director.

Electives

Residents have elective time throughout the three years, with the majority in the third year, allowing them to select clinical areas of concentration. Established electives include Anesthesiology, Cardiology, Emergency Medicine, Hospital/ICU Medicine, Gastroenterology, Infectious Disease, Interventional Radiology, Nephrology, Outpatient Pediatrics, Outpatient Procedures, Public Health, Pulmonology, Rehab Medicine, Woman’s Health, and Wound Care, with a process for creating new electives.

Behavioral Science

The Behavioral Science experience is a longitudinal rotation over the course of the residency program, where residents participate in didactic sessions, counsel patients referred for crisis intervention or brief therapy sessions, and learn counseling skills, DSM-IV diagnoses, use of psychiatric medications, and assessment of psychological issues.

Outpatient Services (Community Medicine)

Residents participate in a variety of clinics including MAT clinic at a local FQHC, Dermatology clinic, Procedure clinic, Eye clinic, and spend time with a local foundation exploring philanthropic work. Rotations also include the University of California, Merced Student Clinic and the Mobile Clinic.

Musculoskeletal

Residents rotate with local orthopedic surgeons, at a community college with trainers for sports injuries, and with a local rheumatologist for rheumatologic conditions. Residents also perform sports physicals at local high schools with faculty.

Other Areas of Curriculum

A POCUS curriculum is incorporated into both didactics and inpatient and outpatient clinic experiences. A Wellness curriculum, led by two third-year residents, is integrated into the didactics. The program is also working on developing a formal Street Medicine curriculum.

Training Locations

Mercy Medical Center Merced serves as the primary inpatient training site. The core outpatient experience for residents occurs at the Family Care Clinic, a licensed Rural Health Clinic in South Merced. Residents also rotate through several other rural locations in Merced County and the University of California, Merced Student Clinic and Mobile Clinic for community medicine experiences.

Our Community

Merced is in the San Joaquin Valley near the foothills of the Sierras, known as "The Gateway to Yosemite," located only one hour and 45 minutes from Yosemite National Park and approximately two hours from San Francisco and the coast. It is a semi-rural area with rich cultural diversity, including large populations of Hmong/Mienh/Thai/Laotian immigrants, Portuguese, Sikhs/Punjabis, and Latino peoples, offering the advantages of a small-town atmosphere. Numerous recreational opportunities include bike paths, multiple neighborhood parks, gyms, an 18-hole golf course, and Lake Yosemite for water sports. Downtown Merced features local restaurants, movie theaters, beer pubs, an art center, and the landmark Merced Theatre for live performances. UC Merced, the 10th University of California campus, has brought new growth and many new cultural activities to the city.
