Essential Guide to Letters of Recommendation for DO Graduates in Med-Psych Residency

Understanding the Role of Letters of Recommendation in Med-Psych for DO Graduates

Letters of recommendation (LoRs) are one of the most influential parts of a residency application—especially in a niche combined program like Medicine-Psychiatry. For a DO graduate pursuing a med psych residency, letters do more than “check a box.” They:

• Validate your clinical competence across both medicine and psychiatry
• Demonstrate that you can thrive in interdisciplinary, integrated care settings
• Help programs understand how your osteopathic training and perspective will add value
• Offer insight into your professionalism, maturity, and readiness for a combined program

For DO graduates, LoRs can also address lingering biases in some allopathic environments by showcasing that you are equally capable, well-trained, and strong clinically. Programs recognize that board scores, transcripts, and CVs provide only part of the picture; nuanced letters are often the deciding factor when choosing who to interview and how to rank applicants.

In the context of the osteopathic residency match and ERAS applications, strong letters can offset modest metrics or a nontraditional path. For competitive and relatively small combined medicine psychiatry programs, they are critical.

This guide is tailored to you as a DO graduate applying to medicine psychiatry combined programs (often called “med psych”). It will walk you through:

• How many LoRs you need and from whom
• How to choose the right letter writers
• Exactly how to get strong LOR letters—step by step
• Unique considerations for DO graduates
• Timing, logistics, and common pitfalls

Core Requirements: How Many Letters and From Which Specialties?

Most Medicine-Psychiatry programs participate in ERAS and follow guidelines similar to categorical internal medicine and psychiatry programs, with additional emphasis on your fit for integrated care.

Typical Letter Requirements for Medicine-Psychiatry

Always verify each program’s website, but in general:

• Total number of LoRs: 3–4 letters (not including the MSPE/Dean’s Letter)
• Preferred breakdown:
  • 1–2 letters from Internal Medicine faculty
  • 1–2 letters from Psychiatry faculty
  • Optional: 1 “flex” letter (e.g., med psych faculty, sub-I director, research mentor, or program director)

Some programs clearly state they want at least one letter in medicine and one in psychiatry. Others are flexible but still expect evidence that you can function at a high level in both domains.

Prioritizing Letter Types

For a DO graduate in a med psych residency application, think about coverage:

1. Clinical Internal Medicine Letter (Required)

   • From an attending who supervised you on inpatient wards, ICU, or a strong outpatient rotation.
   • Should speak to your:
     • Clinical reasoning and diagnostic skills
     • Management of complex medical patients
     • Work ethic, reliability, and ability to function as a near-intern

2. Clinical Psychiatry Letter (Required)

   • From your inpatient psych, CL psychiatry, or outpatient psychiatry attending.
   • Should address:
     • Empathy and communication with patients and families
     • Comfort with psychiatric assessments (suicide risk, psychosis, mood disorders)
     • Ability to work across systems (e.g., social work, nursing, case management)

3. Combined/Bridge Letter (Highly Valuable if Available)

   • From someone who can speak to both medicine and psychiatry, such as:
     • A med psych faculty member
     • A CL (consult-liaison) psychiatrist who saw you caring for medically complex psych patients
     • A rotation in addiction medicine, psychosomatic medicine, or primary care mental health integration
   • This letter is particularly powerful for medicine psychiatry combined programs because it:
     • Demonstrates your genuine interest in integrated care
     • Highlights your ability to think in both biomedical and psychosocial frameworks

4. Department Chair or Program Director Letter (Optional but Helpful)

   • Often required by some programs in medicine or psychiatry.
   • Can be arranged based on:
     • A formal departmental evaluation process
     • A summary letter built from multiple faculty assessments
   • Particularly useful if you’re coming from a DO school with a strong reputation in primary care or psychiatry.

Who to Ask for Letters: Choosing the Right Writers Strategically

Knowing who to ask for letters is just as important as knowing how many letters you need. Strong letters come from people who know you well enough to speak in detail about your performance and potential.

The Ideal Letter Writer Profile

Aim for writers who satisfy as many of these criteria as possible:

1. Direct Clinical Supervisor

   • Someone who directly observed you:
     • Taking histories and performing physicals
     • Presenting on rounds
     • Making and defending management plans
   • Examples:
     • Ward attending on internal medicine
     • Inpatient psychiatry attending
     • Sub-internship (sub-I) supervisor in medicine or psychiatry

2. Knows You Beyond the Surface

   • Worked with you long enough (2+ weeks) to comment on:
     • Growth over time
     • Professionalism and resilience
     • Teamwork and communication style

3. Connected to the Specialty

   • For medicine psych residency:
     • Internal medicine faculty for your medicine-oriented letter(s)
     • Psychiatry faculty for your psych-oriented letter(s)
     • Med psych, CL psych, addiction, or primary care mental health faculty for hybrid/integrated letters

4. Academic or Leadership Standing

   • A well-known or highly respected faculty member in the department can add additional weight, if they know you well.
   • However, a detailed letter from a mid-career, clinically active faculty member who worked closely with you is often more powerful than a vague letter from a department chair who barely knows you.

Specific Suggestions for a DO Graduate in Med Psych

Consider these concrete options:

• Internal Medicine Letters:

  • Inpatient internal medicine attending from your strongest rotation
  • Hospitalist attending from a sub-I or acting internship
  • Outpatient internal medicine or primary care attending, especially with integrated behavioral health exposure

• Psychiatry Letters:

  • Inpatient psychiatry attending with whom you had substantial clinical time
  • CL psychiatry attending, especially if you worked with medically complex psychiatric patients
  • Outpatient psychiatrist who saw you manage chronic psychiatric illness and interface with medical comorbidities

• Integrated/Bridge Letters:

  • Faculty in a med psych clinic, collaborative care model, or integrated primary care-psychiatry clinic
  • CL psychiatrist who saw you manage delirium, capacity assessments, psych consults on medicine floors
  • Addiction medicine or dual diagnosis program faculty

If your school is DO-focused, also identify MD faculty or institutions where you rotated. A strong letter from an allopathic academic center can help reassure programs accustomed to MD applicants that you’ve thrived in that environment as a DO graduate.

How to Get Strong LOR: Step-by-Step Process

Strong letters don’t “just happen.” You need a deliberate strategy before, during, and after each key rotation.

1. Plan Your Rotations Around Letters

Before fourth year or late third year:

• Identify at least:
  • One high-yield internal medicine rotation or sub-I
  • One high-yield psychiatry rotation (inpatient, CL, or sub-I)
  • Opportunities for integrated care experiences, if your school offers them
• Frame these rotations in your mind as:
  • Learning opportunities
  • Auditions
  • Primary sources for your strongest letters of recommendation

2. Perform Intentionally on Key Rotations

To maximize letter strength:

• Show up early, stay prepared, and be engaged
  • Pre-round thoroughly
  • Read about your patients’ conditions and bring management ideas to rounds
• Demonstrate independent thinking
  • Offer differential diagnoses
  • Suggest diagnostic or therapeutic steps (and be open to feedback)
• Practice excellent documentation and follow-through
  • Timely, thorough notes
  • Close loop on labs, imaging, and consult recommendations

For psychiatry rotations:

• Conduct thorough psychiatric interviews
• Learn to perform structured assessments:
  • Suicide risk
  • Violence risk
  • Delirium vs. primary psychosis
• Integrate medical comorbidities and medications into your psychiatric formulation

As a DO graduate, actively use your osteopathic skills when appropriate:

• Functionally oriented physical exams
• Attention to musculoskeletal complaints, pain, and somatization
• Holistic biopsychosocial thinking, which aligns naturally with med psych

Your goal is to give attendings concrete behaviors they can cite in your letter.

3. Signal Your Interest Early

About halfway through a rotation (or sooner):

• Let your attending know:
  • You are a DO graduate applying to medicine psychiatry combined programs
  • You are particularly interested in integrated care and working with medically and psychiatrically complex patients
• Ask:
  • “I’m hoping to use this rotation as a key experience for my residency applications, especially for med psych programs. Are there specific skills or areas you’d like me to focus on to reach that level?”

This invites targeted feedback and gives them a framework for your eventual letter.

4. Ask the Right Question the Right Way

When the rotation is going well and you’ve received positive feedback, it’s time to ask. The most important thing is to ask for a strong letter, not just any letter.

Example script (in person or via email):

“Dr. Smith, I’ve really appreciated working with you on this rotation and learning from your approach to complex internal medicine patients. I’m a DO graduate applying to combined Medicine-Psychiatry residencies and internal medicine programs. Would you feel comfortable writing me a strong letter of recommendation that specifically addresses my performance on this rotation and my potential for med psych training?”

Why this wording matters:

• It gives them an “out” if they can’t be strong advocates
• It encourages honesty and protects you from lukewarm or harmful letters
• It reminds them of your med psych focus so they can tailor content

If they seem hesitant, thank them and consider asking someone else. A neutral or “damning with faint praise” letter can hurt more than it helps.

5. Provide a Helpful Letter Packet

Once they agree, make it easy for them to write a detailed, tailored letter. Provide:

• Updated CV
• Personal statement (even in draft form)
• A brief one-page summary including:
  • Your name and contact
  • Your career goal: “Combined Medicine-Psychiatry residency with a focus on [e.g., integrated primary care, CL psychiatry, addiction, etc.]”
  • Specific patients or cases you worked on together
  • Skills or strengths you hope they can comment on:
    • Clinical reasoning
    • Work ethic
    • Leadership
    • Patient rapport
    • Osteopathic perspective or OMM skills where relevant
• ERAS letter submission instructions and deadlines

This is not “telling them what to write”; it’s giving them scaffolding so they can write specific, vivid examples instead of generic praise.

Special Considerations for DO Graduates in Medicine-Psychiatry

As a DO graduate, your application will be reviewed alongside MD applicants. While most med psych programs are very DO-friendly, your letters can help address potential questions and highlight your unique strengths.

Showcasing the Osteopathic Perspective

Ask at least one letter writer (especially on medicine or integrated rotations) to highlight:

• Your holistic approach to patient care:
  • Attention to lifestyle, social determinants, and family systems
  • Comfort addressing both physical and mental health in one encounter
• Your hands-on clinical skills:
  • Thorough physical exams
  • Understanding of structure-function relationships
• Any OMM/OMT contributions:
  • If you used OMT for pain management, headaches, or somatic symptoms
  • How this improved patient comfort, engagement, or trust

This aligns strongly with the philosophy of medicine psychiatry combined training, where the whole person is always in view.

Addressing Bias and Reassuring Allopathic Programs

A strong LoR for a DO graduate should ideally:

• Comment explicitly on:
  • Your ability to perform at or above the level of interns/residents
  • How you compare to both DO and MD students the writer has supervised
• Highlight:
  • Your success in academic or high-acuity settings
  • Any honors, awards, or standout rotation comments
• If you took both COMLEX and USMLE, the letter does not need to mention scores, but it can note:
  • “She performed at an exceptionally high level clinically, regardless of standardized test metrics.”

The more specific and comparative the praise, the more reassuring it will be to program directors.

Navigating the Osteopathic Residency Match Landscape

Even though most medicine psychiatry combined programs are in the ACGME system, the osteopathic residency match era has shaped how DO graduates are evaluated. Solid letters:

• Signal that you’ve already transitioned well into ACGME-style training environments
• Bolster your candidacy if applying to both:
  • Combined med psych programs, and
  • Categorical internal medicine or psychiatry programs as backup options

For categorical back-ups, you may need program-specific LoR assignments in ERAS (e.g., one letter more focused on internal medicine, another on psychiatry). Plan ahead so your letters are flexible enough to support both goals.

Logistics, Timing, and Common Pitfalls to Avoid

Ideal Timeline for Requesting Letters

For a typical fourth-year DO student applying to med psych:

• End of Third Year / Early Fourth Year:
  • Identify your strongest clinical rotations and target letter writers.
• 2–4 weeks before the end of each key rotation:
  • Ask for the letter, assuming the rotation is going well.
• Late Summer / Early Fall:
  • Aim to have all letters uploaded to ERAS before application submission date (often mid-September).

If you’re a DO graduate taking a research year or applying after a gap, reconnect with your letter writers at least 2–3 months before you’ll need updated letters.

ERAS Mechanics

In ERAS:

• You will:
  • Add each writer’s name and role
  • Assign them to specific programs
  • Generate a unique ERAS LoR ID for each writer
• They will:
  • Upload directly via ERAS (or office staff will)
  • Send their letter confidentially—you will not see it

Double-check:

• That they select the correct specialty focus if they mention it (e.g., medicine psychiatry vs categorical)
• That each program gets the right combination of letters:
  • Med psych programs: at least one medicine, one psychiatry, ideally one integrated if available
  • Pure medicine programs: mostly medicine-oriented letters
  • Pure psychiatry programs: mostly psychiatry-oriented letters

Avoiding Common Pitfalls

Common mistakes and how to avoid them:

1. Waiting too long to ask

   • Solution: Ask during or immediately after the rotation, while your performance is fresh in their mind.

2. Choosing prestige over familiarity

   • Solution: Prefer an attending who knows you well over a big-name faculty who barely remembers you.

3. Not clarifying your career goal

   • Solution: Tell every letter writer you’re applying to medicine psychiatry combined and explain why.

4. Not asking if they can write a “strong” letter

   • Solution: Always include the word “strong” in your ask to filter out lukewarm writers.

5. Forgetting to follow up politely

   • Solution: Send gentle reminders:
     • ~2 weeks after your initial request (if not yet uploaded)
     • Again ~1 week before your internal deadline

6. Using generic letters for all specialties

   • Solution: Request that at least some letters be tailored (medicine-focused, psych-focused, integrated-focused), then assign them strategically on ERAS.

Putting It All Together: Example Letter Strategy for a DO Med-Psych Applicant

Imagine you are a DO graduate with the following experiences:

• Strong inpatient medicine rotation at a large teaching hospital
• Inpatient psychiatry rotation with CL exposure
• Sub-I in internal medicine at an academic center
• Outpatient psychiatry elective with a focus on primary care-psych integration

A smart LoR plan:

1. Letter 1 – Internal Medicine Attending (Sub-I)

   • Focus: Clinical reasoning, responsibility level near an intern, handling of complex medical patients.
   • Use: All med psych programs + all categorical internal medicine programs.

2. Letter 2 – Inpatient Psychiatry Attending with CL Exposure

   • Focus: Psychiatric assessment skills, empathy, interdisciplinary teamwork, work with medically ill psychiatric patients.
   • Use: All med psych programs + all categorical psychiatry programs.

3. Letter 3 – Outpatient Integrated Care Psychiatrist or Med Psych Faculty

   • Focus: True integration of medicine and psychiatry, comfort addressing both physical and mental health in a single visit, passion for combined training.
   • Use: All med psych programs (primary highlight letter).

4. Letter 4 – Department Chair or Core Advisor (Optional but Helpful)

   • Focus: Overall professionalism, reliability, strong performance across core clerkships, supportive summary of your DO training.
   • Use: Selected programs that explicitly request or value chair letters.

This mix gives every medicine psychiatry combined program a balanced, persuasive view of your candidacy.

FAQs: Letters of Recommendation for DO Graduates in Med-Psych

1. How many letters of recommendation do I really need for Medicine-Psychiatry?

Most med psych programs are satisfied with 3 letters, but many applicants submit 4. A safe, strong combination is:

• 1 internal medicine letter
• 1 psychiatry letter
• 1 integrated/bridge letter (if possible)
• Optional: 1 chair/program director or research/mentor letter

Check each program’s website to confirm maximum numbers and any preferences.

2. Do my letters need to come from combined med psych or CL faculty?

No, but it helps. At minimum, you need separate strong letters in internal medicine and psychiatry. Having even one letter from:

• A med psych faculty member
• A CL psychiatrist
• An integrated care or addiction faculty member

…can significantly strengthen your case for a medicine psychiatry combined program by highlighting your fit for integrated practice.

3. As a DO graduate, should I prioritize letters from MD attendings?

Not necessarily. The strength and specificity of the letter matter more than the writer’s degree. However:

• A strong letter from an MD at an ACGME-affiliated hospital or academic center can help reassure allopathic program directors.
• Don’t sacrifice quality for optics. A detailed, glowing letter from a DO attending who knows you well is usually better than a generic MD letter.

Aim for a mix if you can, but always prioritize writers who can best represent your clinical ability and growth.

4. Can I reuse the same letters for med psych, medicine, and psychiatry applications?

Yes, ERAS allows you to assign different letters to different programs, but the same letter can be used across multiple programs. The key is:

• Choose at least one “medicine-heavy” letter and one “psych-heavy” letter for categorical programs.
• For med psych programs, prioritize letters that:
  • Highlight your interest in integrated care
  • Show strength in both clinical medicine and psychiatry

When you ask for the letter, tell the writer that you’re applying to med psych as well as categorical medicine and/or psychiatry so they can write something that works across these contexts.
