The Ultimate Guide for DO Graduates: Researching Internal Medicine Residencies

Understanding Your Goals as a DO Graduate in Internal Medicine

Before you dive into spreadsheets and program websites, you need clarity on what you want and what makes sense for a DO graduate residency path in Internal Medicine.

Think about three dimensions:

1. Professional goals

   • Do you want academic vs community training?
   • Are you interested in primary care, hospital medicine, or fellowship (cards, GI, pulm/crit, heme/onc, etc.)?
   • How important is research or Q.I. work to you?

2. Personal goals

   • Geographic priorities (family, cost of living, lifestyle).
   • Support systems (partner, kids, childcare, visa, etc.).
   • Tolerance for long commutes, weather, or specific regions.

3. DO-specific considerations

   • How DO-friendly is the program?
   • Historical osteopathic residency match presence (number of DOs per class).
   • Program’s comfort with COMLEX vs. USMLE (if you did/did not take USMLE).

Write this down. A written list of priorities makes every later decision—what to research, where to apply, where to interview—much easier.

Example priorities list (DO IM applicant):

• Region: Midwest or Northeast, urban/suburban
• Program type: University-affiliated or strong community program with good fellowship track record
• DO preference: At least 15–20% DOs per class, accepts COMLEX-only
• Interests: Hospital medicine now, possibly cardiology later
• Environment: Collegial, supportive culture; not malignant
• Other: Partner can find job in city >250k population

You will use this priorities list as your filter for evaluating residency programs and creating a structured program research strategy.

Step 1: Build a Target List Before Deep Research

A common mistake is jumping into detailed research on too many programs. Instead, start by building a broad but filtered list, then narrow down.

1. Use Official Databases Strategically

Your first layer of how to research residency programs is using major databases:

• FREIDA (AMA Residency & Fellowship Database)

  • Filter for:
    • Specialty: Internal Medicine (Categorical)
    • Location (regions/states of interest)
    • Program size
    • Community vs university vs university-affiliated
  • Review:
    • Program type
    • Number of positions
    • Visa sponsorship (if applicable)
    • Basic contact info and website

• ERAS / AAMC Residency Explorer (if available to you)

  • Helps compare your metrics (scores, experiences) to previously matched residents at given programs.
  • Particularly helpful for estimating “reach,” “target,” and “safer” programs.

• NRMP data / Program websites

  • Many program sites list:
    • Total number of residents
    • Past residents’ fellowship placements
    • IM board pass rates
    • Rotating hospitals and clinic sites

Create a preliminary list of 40–80 Internal Medicine residency programs (depending on your competitiveness and budget). You’ll refine this later.

2. Identify DO-Friendly Programs Early

For a DO graduate, an early filter is: Will this program realistically consider me?

Look for:

• Current residents’ profiles

  • Check program websites; note:
    • How many DOs per class?
    • Any DOs in chief resident positions?
  • If 0 DOs over several years, proceed with caution.

• Program-specific DO signals

  • Explicit welcome to DO applicants on website.
  • Historically osteopathic programs (before AOA–ACGME merger).
  • Affiliated with schools of osteopathic medicine (e.g., rotation sites, faculty from DO schools).

If a program has no DOs, no COMLEX info, and no explicit DO language, you can still apply, but only if other features strongly match your priorities and/or you have strong metrics.

---

Step 2: Create a Structured Program Research Strategy

Randomly browsing websites leads to burnout. Instead, build a system.

1. Build a Program Evaluation Spreadsheet

Create a spreadsheet (Excel, Google Sheets, Notion—anything you’ll actually use). Include columns such as:

• Basic Info

  • Program name
  • City/State
  • Program type (academic, community, hybrid)
  • Number of categorical IM positions
  • ACGME ID

• DO-Relevant Fields

  • % of DOs in current residents
  • Accepts COMLEX-only? (Yes/No/Unknown)
  • Any osteopathic recognition? (if IM + OMT/osteopathic track)
  • Past or current DO chiefs?

• Training Quality

  • Board pass rate (if published)
  • Fellowship match outcomes
  • Types of affiliated hospitals (county, VA, tertiary referral, community)
  • ICU exposure, subspecialty exposure
  • Night float vs traditional call

• Fit Factors

  • Geographic desirability (1–5)
  • Culture (based on resident comments, social media)
  • Work–life balance indicators (night float, vacation time)
  • Research/QI opportunities
  • Primary care vs subspecialty emphasis

• Practical & Application Strategy Fields

  • Personal competitiveness level (reach/target/safe)
  • Interview likelihood (subjective estimate)
  • Priority score (overall 1–10)
  • Notes and questions for interviews

This structure makes evaluating residency programs systematic instead of emotional.

2. Assign Objective and Subjective Scores

For each program, rate key factors on a consistent scale, for example:

• Location (1–5)
• DO-friendliness (1–5)
• Training strength (1–5)
• Lifestyle (1–5)
• Overall fit (1–10)

You don’t have to be perfect; the goal is relative comparison.

Example (simplified):

Program	DO-friendly (1–5)	Training strength (1–5)	Location (1–5)	Overall fit (1–10)
A	5 (30% DOs)	4	3	8
B	2 (rare DOs)	5	5	7
C	4 (DO chiefs)	3	2	6

This helps you prioritize which programs deserve deeper research and effort.

Step 3: Deep Dive into Each Program (Beyond the Brochure)

Once you have a working list, deepen your research. This is where most DO applicants either excel—or waste time. Focus on high-yield sources.

1. Use the Program Website Efficiently

When researching internal medicine residency programs, approach each website like a structured chart:

Key pages to review:

• Program Overview

  • Type (academic vs community)
  • Rotating hospitals
  • Mission and values
  • Program size (small: ≤20 residents per year; medium; large: >40)

• Curriculum

  • Inpatient vs outpatient time balance
  • ICU exposure
  • Night float vs 24-hour call
  • Presence of subspecialty rotations (cards, pulm/crit, GI, heme/onc, ID, rheum, etc.)
  • Continuity clinic model (traditional, block, resident-run)

• Residents & Alumni

  • DO representation per class
  • Where graduates go: hospitalist vs fellowship, academic vs community
  • Fellowships obtained (cards, GI, pulm/crit, etc.)

• Faculty & Leadership

  • Any DO faculty in leadership? (PD, APD, chiefs, core faculty)
  • Presence of fellowship programs (an academic environment indicator)

• Scholarly Activity

  • Publication lists
  • QI projects
  • Research infrastructure (mentors, statisticians, time protected for scholarly work)

For each program, summarize key points in your spreadsheet under “Notes.”

2. Consider DO-Friendliness in Detail

For the osteopathic residency match in IM, your odds improve when a program is clearly DO-comfortable. Look for:

• Language on website like:
  • “We welcome applications from DO candidates.”
  • “We accept COMLEX or USMLE.”
• Historical data:
  • Multiple DOs every year, not just one isolated person.
• Program culture:
  • DO chiefs or DO faculty as visible leaders.

If you only have COMLEX, confirm:

• That the program explicitly accepts COMLEX-only, or
• Contact the coordinator/PD for clarification before applying, especially if application fees are a concern.

3. Use Social Media and Online Presence

Many IM programs now maintain:

• Instagram/Twitter/X accounts

  • Resident life photos
  • Wellness events
  • Academic conferences
  • Social cohesion (does it look collaborative or isolating?)

• YouTube / Virtual Open Houses

  • Watch videos of:
    • Residents talking about culture
    • PD explaining program philosophy
    • Walkthroughs of hospitals or clinics

This gives you a real sense of personality and values that formal websites may not reflect.

4. External Review Platforms (Use Cautiously)

You may see anonymous forums, review sites, and Reddit threads. These can be:

• Sometimes helpful for:

  • Flagging truly toxic, unsafe, or malignant environments.
  • Highlighting major structural problems (chronic understaffing, severe duty-hour violations).

• Often misleading due to:

  • Small sample size.
  • Bitter ex-residents or people who rotated briefly.
  • Outdated information (culture can change significantly over 3–5 years).

Use such sources only as soft flags, then cross-check with more reliable data.

Step 4: Evaluating Training Quality and Career Outcomes

To make smart decisions, prioritize how the program will train you and set you up for your future, not just name recognition.

1. Clinical Training Strength

Key questions when evaluating residency programs for IM:

• Patient mix

  • Does the hospital serve a diverse population (urban underserved, suburban insured, rural medicine)?
  • Are there county or VA hospitals? (often rich pathology and autonomy)

• Acuity and autonomy

  • Do residents run codes and rapid responses?
  • What is the ICU structure (open vs closed, resident-led vs fellow-dominated)?
  • Are residents primary decision makers, or mostly note-writers?

• Breadth of pathology

  • Tertiary/quaternary care centers see rare disease and complex pathology.
  • Community hospitals emphasize common conditions, efficiency, and real-world practice.

As a DO graduate, both can work; choose based on your career goals and learning style.

2. Fellowship and Career Outcomes

If you’re considering an eventual fellowship, evaluate:

• Fellowship match lists

  • Are graduates matching into your areas of interest (e.g., cards, GI, pulm/crit) and at solid institutions?
  • Do they place fellows mostly internally, regionally, or across the country?

• Internal fellowships

  • Programs that have in-house fellowships (cards, GI, etc.) often have:
    • Stronger academic environment
    • More research opportunities
    • Fellows who can teach you (pros) but may also take procedures (cons)

If your primary goal is hospital medicine or primary care, then:

• Look at hospitalist and outpatient career placement.
• Check whether graduates feel confident and independent at graduation.

3. Board Pass Rates and Educational Support

Ask:

• Does the program publish ABIM board pass rates?
  • Consistently high rates (≥90%) are reassuring.
• Formal educational structure:
  • Daily or near-daily didactic conferences.
  • Morning reports, noon conference, grand rounds.
  • Protected education time (paging covered by others during lectures).

For a DO graduate transitioning from a mixed osteopathic/allopathic environment, a strong educational framework can smooth your transition, especially if your school had variable exposure to complex tertiary care.

Step 5: Culture, Fit, and Lifestyle—What You Can’t See on Paper

The IM match is not just about getting a spot; it’s about finding a place you can sustain three intense years.

1. Assessing Culture from a Distance

Before interview season, you can infer culture from:

• Resident bios and photos

  • Do they seem diverse (backgrounds, interests)?
  • Are their hobbies and personalities described, suggesting the program values them as people?

• Social media

  • Are there regular posts about:
    • Wellness events
    • Retreats
    • Resident recognition/awards
    • Team-building activities

• Program language

  • Mission statements referencing support, wellness, inclusion, and mentorship—and showing specific actions, not just vague statements.

As a DO, culture is critical. You want programs that are used to integrating learners from varied backgrounds and value osteopathic perspectives.

2. Workload and Lifestyle

Internal Medicine is demanding everywhere, but balance varies:

Key aspects to look for:

• Call structure

  • Night float vs 24-hour call.
  • Presence of “short call”/“long call” systems.

• Days off and vacation

  • Typical: 3–4 weeks vacation/year; weekly day off guaranteed.
  • Be cautious of programs that seem to push untold extra calls without clear structure.

• Ancillary support

  • Are there phlebotomy, respiratory therapy, case managers, social work support?
  • Heavy scut work can erode your learning and well-being.

These are often best clarified during interviews and open houses, but you can pre-flag questions now.

Step 6: Tailoring Your Program List as a DO Applicant

After gathering data, you should refine and tier your list.

1. Categorize: Reach, Target, and Safer Programs

Consider:

• Your COMLEX/USMLE scores and class rank.
• Research and leadership experiences.
• Any red flags or unusual pathways.

Then, divide your list:

• Reach programs
  • More competitive university programs, top fellowship-producing institutions.
  • Fewer DOs historically but still some representation.
• Target programs
  • Programs where your metrics and experiences align with recent matched DOs.
  • Healthy DO presence or explicit DO-friendly stance.
• Safer programs
  • Community or hybrid programs with strong DO representation.
  • Perhaps less name recognition but solid training.

For most DO IM applicants, a healthy application list might include:

• 20–30% reach programs
• 40–60% target programs
• 20–30% safer programs

Adjust numbers based on your competitiveness and finances.

2. Special Considerations for COMLEX-Only Applicants

If you did not take USMLE:

• Prioritize programs that clearly state:
  • “COMLEX accepted” or “COMLEX-only accepted.”
• When in doubt, email the program coordinator:
  • Ask briefly and professionally whether COMLEX-only applicants are considered.
• Use DO-specific advising (school advisors, alumni) to ensure your list isn’t overly top-heavy.

---

Step 7: Using Contacts, Rotations, and Open Houses

1. Leverage Away Rotations/Sub-Internships (If Possible)

For Internal Medicine, a strong sub-I at a program can:

• Show them you can perform at or above the level of their typical resident.
• Give you first-hand insight into culture, workload, and support.
• Provide powerful letters of recommendation.

As a DO, away rotations at historically MD-dominated programs can demonstrate equivalence and break implicit biases.

However:

• Choose only a few; don’t over-rotate.
• Prioritize programs you genuinely want to attend and that you might be competitive for.

2. Attend Virtual or In-person Open Houses

Many IM programs hold:

• Virtual meet-and-greets
• Information sessions with PDs and residents
• Q&A sessions focused on culture, curriculum, and wellness

Use these to:

• Ask DO-relevant questions:
  • “How many DOs are currently in your program?”
  • “Do you accept COMLEX-only applicants?”
  • “Are there DO faculty or osteopathic-focused initiatives?”
• Clarify subtler aspects of training and culture.

Keep notes from these events in your spreadsheet—interview season moves fast, and memory fades.

3. Network with Alumni and Current Residents

Ask your school’s:

• Internal medicine advisors
• Recent DO graduates
• Residents you know from rotations

Questions to ask:

• “Which IM programs were especially welcoming to DOs?”
• “Any programs you’d recommend avoiding?”
• “How did you feel about your preparation for fellowship or hospitalist jobs from your program?”

A 15–20 minute Zoom or phone call can save you dozens of hours of guesswork.

---

Step 8: Finalizing Your Application Strategy

By the time ERAS opens, you should have:

1. A finalized program list with:

   • Tiering (reach/target/safer).
   • DO-friendliness scores.
   • Key pros/cons.

2. Tailored talking points for your personal statement and interviews:

   • How your osteopathic background shapes your approach to Internal Medicine.
   • Why you value certain features (e.g., continuity of care, underserved populations, research).

3. A set of specific questions for each program, such as:

   • “How are DO residents supported in transitioning to a largely allopathic environment?”
   • “Can you tell me about recent DO graduates—what are they doing now?”
   • “How does your program support residents interested in [your goal: fellowship X, hospitalist path, primary care, etc.]?”

Your program research strategy should help you feel in control—not overwhelmed—throughout the application and IM match process.

FAQs: Researching Internal Medicine Programs as a DO Graduate

1. Should I prioritize DO-friendly programs over prestige?

For most DO graduates, consistent DO-friendliness and strong training matter more than pure name recognition. A mid-tier program where DOs thrive, match into good fellowships, and feel supported is usually better than a prestigious program with no DOs and uncertain support. If you have exceptional metrics and experiences, you can include more reach programs—but still balance your list with solid DO-friendly options.

2. How many Internal Medicine residency programs should a DO graduate apply to?

Numbers vary by competitiveness, but for many DO applicants to IM:

• A typical range is 30–60 programs.
• More competitive applicants with strong board scores and research may do well with fewer.
• If your metrics are weaker or you’re geographically restricted, you might lean toward the higher end.
  Work with your advisor to personalize your range, and always consider your budget.

3. Is it a problem if I only have COMLEX and not USMLE?

It’s not automatically a problem, but it does limit some options. Many IM programs are comfortable with COMLEX-only, particularly those with a significant DO presence. However, some university or highly competitive programs still strongly prefer or require USMLE. If you are COMLEX-only:

• Carefully check each program’s stated requirements.
• Email coordinators to clarify when the website is unclear.
• Focus on programs with a known history of matching DOs.

4. How can I tell if a program is malignant or has a toxic culture?

No single data point proves malignancy, but warning signs include:

• Repeated, consistent negative reviews across multiple years and platforms.
• Very high resident turnover or unexplained gaps in resident lists.
• Residents who look exhausted or disengaged in photos, with little evidence of wellness or camaraderie.
• Vague or defensive answers from residents when you ask about workload, support, or program responsiveness to feedback.

Use your interviews and open houses to directly and politely ask residents about support, feedback, and responsiveness from leadership. Combine their answers with your prior research to make an informed judgment.
