Federation of State Medical Boards
The Federation of State Medical Boards (FSMB) is a nonprofit organization founded in 1912 that represents the 70 state medical boards in the United States, acting as a national forum to support regulatory efforts aimed at ensuring competent physician practice and public safety through standardized licensure and disciplinary processes.[1]FSMB facilitates coordination among member boards by providing essential services, including the Federation Credentials Verification Service (FCVS) for verifying physician credentials, co-administration of Step 3 of the United States Medical Licensing Examination (USMLE), and the Physician Data Center for accessing licensure and disciplinary records.[2][3][4] Its mission emphasizes patient safety, medical practice integrity, and access to quality healthcare via resources, data, legislative advocacy, and best-practice sharing.[1]
Key initiatives include advocating for uniform standards in medical education, postgraduate training, and examination requirements, as well as technological solutions to streamline licensing amid evolving healthcare demands.[5][6] Notable achievements encompass over a century of promoting high regulatory standards and publications documenting the evolution of medical licensing.[7]
The organization has encountered historical criticisms for discriminatory practices affecting international medical graduates, osteopathic physicians, women, and minorities in licensure processes, alongside contemporary debates over the extent of boards' authority to discipline physicians for disseminating contested medical views, such as during the COVID-19 pandemic.[8][9]
History
Founding and Early Development (1912–1950)
The Federation of State Medical Boards (FSMB) was formally established on February 28, 1912, through the merger of two predecessor organizations: the National Confederation of State Medical Examining and Licensing Boards, founded in 1890 to promote uniform educational standards, and the American Confederation of Reciprocating Examining and Licensing Boards, established in 1902 to facilitate interstate license reciprocity.[10] The merger, negotiated in Chicago between February and March 1911, aimed to resolve tensions between long-term educational reform and immediate reciprocity needs, creating a unified forum for state boards to address inconsistencies in medical licensing practices across jurisdictions.[10] By 1913, the FSMB had 22 charter member boards and adopted bylaws establishing minimum educational prerequisites for licensure and qualifications for reciprocity endorsement.[10] Initial operations consisted of small annual meetings of board executives, with no permanent staff, headquarters, or significant funding—evidenced by a 1913 financial balance of just $250—limiting its early national influence.[11] Early leadership emphasized standardization amid challenges like varying state exam rigor and physician mobility issues. George H. Matson served as the first secretary in 1912, followed by Otto V. Huffman from 1912 to 1915, and Walter L. Bierring, who assumed the role of secretary-treasurer and editor of the Federation Bulletin in 1915, sustaining the organization through nearly five decades until 1961.[12] Under presidents like David Strickler (1917–1924), the FSMB identified priorities including uniform practice acts, licensing examinations, medical school classification, and tracking disciplined physicians, while endorsing the National Board of Medical Examiners in 1916 to promote rigorous testing.[11] By 1915, nearly all states required licensing exams, with New Mexico as a notable exception, reflecting gradual progress toward consistency.[11] From the 1920s to 1950, the FSMB shifted from broad reciprocity to selective endorsement due to concerns over licensee character and training quality, while advocating for enhanced prerequisites. By 1929, 43 of 48 states mandated 1–2 years of college coursework for licensure, and 14 required hospital internships; failure rates on exams averaged no more than 12% in 44 of 51 boards, indicating emerging standardization.[11] By 1932, 94% of licensees originated from approved medical schools, underscoring the FSMB's role in elevating entry barriers.[11] Bierring's tenure, overlapping with the Great Depression and World War II, involved maintaining a repository of disciplinary actions—initiated since 1912—and issuing bulletins to share best practices, though the organization remained lean without a fixed national office until later decades.[13][8]Post-War Expansion and Standardization Efforts (1950–2000)
Following World War II, the Federation of State Medical Boards (FSMB) intensified efforts to standardize physician licensure amid a surge in medical school enrollments and physician supply, driven by federal initiatives like the GI Bill and expanded residency programs that increased the U.S. physician workforce from approximately 200,000 in 1950 to over 600,000 by 2000.[14][7] This period saw FSMB advocate for uniform regulatory practices to address interstate physician mobility and varying state standards, culminating in the 1956 publication of The Essentials of a Modern Medical Practice Act, a model policy that guided states in updating licensing laws to emphasize competence verification and public protection.[7] A pivotal standardization initiative was the 1968 introduction of the Federation Licensing Examination (FLEX), co-developed with the National Board of Medical Examiners (NBME) to provide a uniform clinical skills assessment, initially adopted by seven states and expanding to all 50 by 1979, thereby reducing discrepancies in evaluating international medical graduates and domestic candidates seeking licensure across jurisdictions.[15][7] Complementing this, FSMB launched the Board Action Data Bank in 1962 to systematically track disciplinary actions, with full participation from all state boards by 1981, enabling real-time sharing of adverse information to prevent unfit physicians from relocating unchecked.[7] In 1966, FSMB formalized its nonprofit status as a 501(c)(6) organization, facilitating broader administrative expansion and resource allocation for regulatory support.[7] By the 1980s and 1990s, FSMB addressed evolving challenges through further innovations, including the 1980 establishment of the FSMB Foundation for research in medical regulation, the 1985 revision of FLEX to enhance reliability, and the 1988 launch of the Special Purpose Examination (SPEX) with NBME for assessing lapsed competencies.[7] The most significant milestone was the 1991 creation of the United States Medical Licensing Examination (USMLE), jointly sponsored by FSMB and NBME, which replaced FLEX by 1994 and integrated basic science, clinical knowledge, and skills into a three-step sequence accepted nationwide for licensure, streamlining processes amid rising IMG applications and graduate mobility.[3][7] Supporting this, the 1995 Federation Credentials Verification Service (FCVS) standardized document authentication for applicants, while the 1999 All-Licensed Physicians project improved national licensure data accuracy, reflecting FSMB's role in fostering evidence-based uniformity without federal overreach.[7]Modern Era and Digital Transformations (2000–Present)
In 2000, the FSMB launched the Disciplinary Alert Service, enabling real-time, 24-hour electronic notifications of disciplinary actions taken by state medical boards against physicians, thereby improving interstate information sharing and regulatory efficiency.[7] This initiative marked an early step in digitizing oversight mechanisms, building on the Federation Credentials Verification Service (FCVS), which had transitioned to electronic primary-source verification of core credentials like medical education and postgraduate training by the early 2000s.[16] The FSMB's Physician Data Center (PDC), originating from a 1999 project for routine electronic submission of licensure data from state boards, further centralized digital access to disciplinary and licensure histories, facilitating queries by regulators and healthcare entities.[7][17] To address barriers in multi-state practice amid growing physician shortages, the FSMB introduced the Uniform Application in 2009, an electronic tool that standardized and reduced redundant data entry for physicians, physician assistants, and residents seeking licenses across states.[7] In 2011, the FSMB published its inaugural electronic Census of Actively Licensed Physicians, a biennial digital dataset aggregating workforce data from all 70 state medical boards to inform policy on distribution and demographics.[7] These efforts culminated in support for the Interstate Medical Licensure Compact (IMLC), proposed at an FSMB meeting in 2013, with model legislation finalized in September 2014 and the commission activated in 2015 after seven states enacted it.[18][19] The IMLC's online application portal expedites licensure for qualified physicians, issuing 3,426 licenses by April 2018 and surpassing 11,000 by 2020, with 39% of initial licenses in participating states processed through the compact in 2023.[20][21][22] The rise of telemedicine prompted the FSMB to adopt a Model Policy for the Appropriate Use of Telemedicine Technologies in 2014, offering guidelines for state boards on digital establishment of physician-patient relationships, asynchronous consultations, and interstate prescribing without physical exams in certain cases.[23] Updated in 2022, the policy emphasized technology-neutral standards while requiring licensure or compacts for cross-border practice.[24] During the COVID-19 pandemic, the FSMB tracked over 40 states' temporary waivers for telehealth licensure requirements and launched Provider Bridge in 2020, a digital platform verifying credentials for volunteer physicians to enable rapid deployment across jurisdictions.[25][26] In parallel, the FSMB expanded PDC access free-of-charge to hospitals in March 2020 for emergency credentialing and has pursued blockchain-enabled digital credentials through collaborations like with Learning Machine, aiming for tamper-proof, portable verification to reduce administrative burdens.[27][28]Organizational Structure
Governance and Leadership
The Federation of State Medical Boards (FSMB) operates under a governance structure centered on its House of Delegates, which serves as the primary policy-making body comprising delegates from its 70 member state medical and osteopathic licensing boards.[29] The House convenes annually to establish strategic priorities, approve budgets, and elect members of the Board of Directors, ensuring representation from diverse state jurisdictions and alignment with regulatory needs across the United States.[30] The Board of Directors, accountable to the House, holds responsibility for the organization's administration, strategic oversight, and implementation of policies, including setting goals for the President and CEO, managing financial resources, and approving annual budgets.[31] Composed of elected officers, nine directors-at-large, and two staff fellows, the Board includes at least three members with backgrounds in osteopathic medicine to reflect the dual MD/DO regulatory landscape; officers are typically serving or former state board members selected for their expertise in medical regulation.[32] Elected positions such as chair-elect and treasurer involve staggered terms—chair-elect serves one year in that role before ascending to chair for one year, followed by immediate past chair—fostering continuity while preventing entrenched leadership.[33] Executive leadership is led by the President and Chief Executive Officer (CEO), who manages day-to-day operations, executes Board directives, and represents FSMB in national advocacy; as of 2025, Humayun J. Chaudhry, DO, MACP, holds this position, appointed for his prior experience in medical education and policy.[34] Supporting the CEO are senior staff including a chief of staff, chief operating officer, and specialized roles in legal, finance, and policy, who coordinate with the Board to advance initiatives like licensure standardization and data-driven regulation.[29] Recent Board elections, such as those in May 2025, underscore the rotational nature of leadership, with George M. Abraham, MD, MPH, from Massachusetts, assuming the chair role to guide efforts on physician mobility and public safety.[30] This structure balances state-level autonomy with national coordination, though critics have noted historical challenges in addressing regulatory inconsistencies due to varying state influences on Board composition.[8]Membership Composition
The membership of the Federation of State Medical Boards (FSMB) consists primarily of 71 institutional member medical boards, encompassing all state and territorial licensing authorities for allopathic (MD) and osteopathic (DO) physicians across the 50 U.S. states, the District of Columbia, Puerto Rico, Guam, the Northern Mariana Islands, and the U.S. Virgin Islands.[35] These boards, which joined progressively since FSMB's founding in 1912, include combined MD/DO entities in most jurisdictions as well as separate boards where applicable (e.g., distinct MD and DO boards in states like Alabama, Arizona, and Missouri), enabling collective representation in national regulatory efforts.[36] Each member board holds voting privileges in FSMB's House of Delegates and accesses shared resources for licensure, discipline, and policy development.[37] Complementing the institutional members are individual categories designed to engage board personnel. Fellows include Board Member Fellows—current or former board members eligible for up to 36 months post-service—and Staff Fellows, limited to one administrative designee per member board, both of whom may participate in FSMB committees, elections, and educational programs.[37] Honorary Fellows status extends to former Fellows three years after their service ends, preserving access to continuing medical education, the Journal of Medical Regulation, and networking events.[37] Associate Members comprise additional board staff nominated by member boards beyond the Staff Fellow allocation, with privileges ceasing upon employment termination and mirroring those of Fellows for professional development support.[37] This structure ensures that FSMB's membership reflects the decentralized nature of U.S. medical regulation while fostering collaboration among regulators, with individual affiliations tied directly to active board service to maintain focus on public protection objectives.[38]Core Functions
Support for State Medical Licensing
The Federation of State Medical Boards (FSMB) supports state medical licensing by providing centralized tools and resources that facilitate credential verification, application processing, and regulatory standardization, enabling boards to maintain public protection while reducing administrative burdens.[2] One primary service is the Federation Credentials Verification Service (FCVS), which allows physicians and physician assistants to compile and verify core credentials—including medical education, postgraduate training, and examination history—in a secure repository accessible to participating state boards, thereby minimizing redundant documentation requests across jurisdictions.[16] As of 2023, FCVS serves over 70 state medical and osteopathic boards, processing applications that support initial licensure, relicensure, and interstate mobility.[39] FSMB further streamlines licensing through the Uniform Application for Licensure (UA), a web-based platform launched to standardize data collection for physician applicants seeking licenses in multiple states without supplanting individual board authority.[40] The UA integrates with FCVS profiles, allowing boards to review pre-verified information and state-specific supplements, which has been adopted by dozens of boards to expedite reviews amid rising application volumes.[40] Complementing these, FSMB disseminates the annual State Medical Licensure Requirements compendium, detailing each jurisdiction's criteria for initial and renewal licensure, including examination sequences like the USMLE, to aid boards in consistent enforcement.[4] In addition to operational tools, FSMB offers educational resources and policy guidance for board staff and members, such as modules on licensure processes and best practices derived from member consultations, which emphasize efficient verification and disciplinary integration into licensing decisions.[41] These include the Guidelines for the Structure and Function of a State Medical and Osteopathic Board, updated in 2024, which recommend protocols for licensure investigations and appeals to ensure procedural fairness.[42] FSMB also provides data from its physician censuses and disciplinary databases, enabling boards to assess workforce needs and risk factors during licensure evaluations.[38] Through these mechanisms, FSMB promotes uniformity in licensing standards without federal overreach, as state boards retain final approval authority.[43]Administration of Licensing Examinations
The Federation of State Medical Boards (FSMB) co-owns the United States Medical Licensing Examination (USMLE) program alongside the National Board of Medical Examiners (NBME), establishing a standardized three-step evaluation system accepted by all U.S. state medical boards for initial physician licensure.[44] FSMB's primary administrative role centers on USMLE Step 3, the final examination assessing a candidate's readiness for unsupervised practice in delivering general medical care, including patient management across diverse clinical scenarios.[45] This step, typically taken after completion of at least one year of postgraduate training, emphasizes foundational biomedical knowledge, biostatistics, epidemiology, and application of ethical principles in ambulatory and inpatient settings.[46] FSMB manages the operational aspects of Step 3, including eligibility verification—which requires passing USMLE Steps 1 and 2, holding an MD or DO degree, and ECFMG certification for international medical graduates—application processing, issuance of scheduling permits, and delivery of score reports to licensing authorities.[47] The examination is computer-based, offered year-round at Prometric test centers in the United States (except during the first two weeks of January and major holidays), with a 2025 application fee of $935 plus a $205 international surcharge where applicable.[48] FSMB also oversees transcript services, enabling candidates to request official USMLE score reports for licensure applications or residency programs.[49] In mid-2025, FSMB assumed centralized responsibility for all USMLE-related services for international medical graduates, encompassing registration, score reporting, and eligibility for Steps 1, Step 2 Clinical Knowledge (CK), and Step 3, while U.S. medical graduates continue using NBME for Steps 1 and 2.[50] This shift aims to streamline processes but maintains NBME's role in content development and scoring for earlier steps. FSMB supports state boards by compiling and updating state-specific licensure requirements, such as time limits for completing the USMLE sequence (e.g., 7–10 years in most jurisdictions) and maximum attempts at Step 3 (often limited to three before requiring additional training).[6] Beyond direct administration, FSMB facilitates uniformity in exam usage for licensure by providing data on pass rates, attempt limits, and postgraduate training prerequisites, though it does not oversee the Comprehensive Osteopathic Medical Licensing Examination (COMLEX-USA), which serves as an alternative for DO candidates and is administered by the National Board of Osteopathic Medical Examiners.[51] State boards determine acceptance of either exam sequence, with FSMB advocating for consistent standards to protect public safety without imposing federal mandates.[4]Credential Verification and Mobility Services
The Federation Credentials Verification Service (FCVS), operated by the FSMB since 1996, serves as a centralized repository for primary-source verified core credentials of physicians and physician assistants, facilitating licensure applications across state medical boards.[16] It verifies unchanging elements such as medical education transcripts, postgraduate training records, examination scores (including USMLE or COMLEX-USA), and identity documents, creating a lifetime profile that applicants can reuse for multiple purposes, including state licensure, hospital privileges, and employment.[52] In 2024, FCVS delivered 73,060 verified profiles to state medical boards, with an average processing cycle time reduced to 14 days through process improvements.[53] The service is accredited by the National Committee for Quality Assurance (NCQA) and aligns with The Joint Commission's ten principles for primary source verification, ensuring standardized reliability for boards.[16] Complementing FCVS, the FSMB's Uniform Application (UA) provides a web-based platform for physicians to submit a single core licensure application to multiple participating state boards, streamlining the process for those seeking multistate practice privileges.[40] Over 60 state boards accept the UA, which integrates seamlessly with FCVS profiles to minimize redundant documentation and verification efforts.[54] This integration reduces administrative burdens, as boards can access pre-verified FCVS data directly, enabling faster approvals for physicians relocating or expanding practice across jurisdictions.[55] These services collectively enhance physician mobility by addressing key barriers in interstate credentialing, such as inconsistent state requirements and repeated primary source checks, without compromising regulatory oversight.[56] For international medical graduates, FCVS coordinates with the Educational Commission for Foreign Medical Graduates (ECFMG) to verify ECFMG certification status, further supporting global-to-U.S. transitions.[52] Costs include an initial application fee of approximately $400 for physicians, plus per-profile fees for board submissions, with profiles remaining valid indefinitely for updates and reuse.[57] By standardizing verification, FCVS and UA promote efficient resource allocation for boards while allowing physicians to maintain active profiles for ongoing mobility needs.[58]Policy Development and Advocacy
Establishment of Regulatory Standards
The Federation of State Medical Boards (FSMB) establishes regulatory standards primarily through the development of model policies, guidelines, and position statements that serve as voluntary frameworks for its 70 member state and territorial medical and osteopathic boards.[42] These standards aim to foster consistency in licensure, discipline, and practice oversight while preserving state autonomy in implementation.[59] FSMB's efforts emphasize evidence-based approaches, drawing from clinical guidelines, peer-reviewed research, and expert input to address evolving medical practices and public safety concerns.[60] Model policies and guidelines are developed via collaborative processes involving FSMB workgroups, special committees such as the Ethics and Professionalism Committee, and input from state board representatives.[61] Drafts undergo public comment periods for stakeholder feedback before final adoption by the FSMB House of Delegates or Board of Directors, ensuring broad consensus among regulatory experts.[59] Periodic reviews incorporate new data and practices; for instance, policies are updated based on emerging trends like technological advancements or substance use management.[61] This structured methodology promotes reliability, with assessments of care compliance relying on qualified medical experts who apply criteria akin to Federal Rule of Evidence 702, including recent practice experience and specialty certification.[60] Historically, FSMB's standardization initiatives trace to 1914, when it first issued guidance on essential elements of medical practice acts and board structures to address variability in state regulations.[42] In 1956, FSMB published A Guide to the Essentials of a Modern Medical Practice Act, derived from consultations with licensing authorities and analyses of best practices across jurisdictions.[42] Subsequent evolutions culminated in the 2018 adoption of Guidelines for the Structure and Function of a State Medical and Osteopathic Board, refined in 2021 and 2024 to incorporate innovations in education, impairment policies, and disciplinary procedures.[42] These documents outline core principles for board composition, licensing criteria, and enforcement, adaptable to local contexts yet aligned for interstate reciprocity.[42] Prominent examples include the Model Policy for the Appropriate Use of Telemedicine Technologies, adopted in April 2014 and updated in 2022, which delineates requirements for establishing physician-patient relationships remotely and ensures equivalent standards to in-person care.[61] Similarly, Strategies to Avoid Misuse and Abuse of Opioids, approved in April 2024, supersedes prior versions and provides risk assessment tools, prescribing limits, and monitoring protocols based on clinical evidence.[61] The 2023 Considerations for Identifying Standards of Care directs boards to benchmark against national guidelines from entities like the Agency for Healthcare Research and Quality (AHRQ) and Centers for Disease Control and Prevention (CDC), prioritizing scientific consensus to minimize unwarranted practice variations.[60] Adoption of these standards by state boards has enhanced regulatory harmonization, facilitating physician mobility while upholding competence and accountability.[59]Interstate Licensure Initiatives
The Federation of State Medical Boards (FSMB) developed model legislation for the Interstate Medical Licensure Compact (IMLC), an agreement designed to expedite the licensing process for qualified physicians seeking to practice across multiple participating jurisdictions while maintaining individual state regulatory authority.[62][7] The compact requires physicians to hold a full, unrestricted license in a State of Principal License (SPL) and meet eligibility criteria, including passing required examinations, undergoing criminal background checks, and demonstrating good standing without significant disciplinary history.[63] Once approved through the SPL, applications for additional state licenses are forwarded electronically to other compact states, reducing redundant paperwork and processing times from months to weeks in many cases.[64] Enacted after FSMB began drafting in 2013, the IMLC achieved legal status as a commission on April 15, 2015, when Alabama became the seventh participating state, with operations commencing in 2017.[65][18] As of October 2024, the compact is active in 40 states, the District of Columbia, and Guam, having issued nearly 118,000 licenses since inception, including over 11,000 by August of an earlier year with accelerated issuance during the COVID-19 pandemic.[22][21] In 2023, 39 percent of initial licenses in participating states were granted via the IMLC pathway, demonstrating substantial adoption for interstate practice, particularly in telemedicine and addressing physician shortages in rural areas.[22] FSMB supports implementation through advocacy, technology platform enhancements, and tracking of related state legislation.[66] The IMLC preserves state sovereignty, as participating boards retain discretion to approve or deny licenses based on local standards, and it does not supersede traditional licensure pathways.[67] Empirical data indicate benefits such as improved physician mobility and access to care, with studies showing increased physician practice growth and patient access post-adoption without evidence of compromised public safety.[68] Criticisms, primarily from some specialty boards, argue it falls short of full reciprocity and may not uniformly enforce standards across states, potentially complicating disciplinary coordination, though no widespread data supports lowered care quality.[69] FSMB continues advocacy for expansions, including a 2023 federal grant to integrate physician assistants and bolster secure data sharing.[70]Responses to Public Health and Technological Challenges
The Federation of State Medical Boards (FSMB) has developed model policies to address the opioid epidemic, emphasizing risk mitigation in prescribing while supporting access to evidence-based treatments for opioid use disorder. In 2013, FSMB updated its "Model Policy on the Use of Opioid Analgesics in the Treatment of Chronic Pain," which advises physicians to assess patient risk factors, use urine drug testing, and check prescription drug monitoring programs before initiating long-term opioid therapy. A 2024 position statement reaffirmed support for controlled substance policies but stressed individualized care to avoid under-treatment of pain, drawing from data showing overdose deaths peaked at over 100,000 annually in the U.S. by 2021.[71] These guidelines have influenced state board regulations, with FSMB tracking adoption across jurisdictions to standardize practices amid varying state laws on controlled substances.[72] During the COVID-19 pandemic, FSMB facilitated regulatory flexibility by compiling a resource directory for state boards, including emergency licensure waivers and telemedicine expansions to maintain care access amid lockdowns beginning in March 2020.[73] It also issued grants through the FSMB Foundation in 2021 to evaluate pandemic lessons and improve regulatory strategies for future crises, funding state-level analyses of physician workforce strains and policy adaptations. In July 2021, FSMB's Board of Directors warned that disseminating COVID-19 vaccine disinformation could warrant disciplinary review by state boards, citing risks to public trust in medicine, though a 2024 survey indicated only 12 state boards had acted on such cases by then, with limited enforcement overall.[74][75] On technological fronts, FSMB has guided state boards toward integrating telemedicine, accelerating post-2020 due to pandemic demands. Its April 2022 "Model Policy for the Appropriate Use of Telemedicine Technologies in the Practice of Medicine" requires establishing a valid physician-patient relationship via audio-video interaction for most encounters, while permitting exceptions for follow-ups or asynchronous tech if standards of care are met, updating 2014 principles to reflect interstate practice growth.[23] This policy supports compacts like the Interstate Medical Licensure Compact, administered by FSMB since 2014, which has issued over 5,000 licenses by 2023 to enable cross-state telehealth.[76] Addressing artificial intelligence (AI), FSMB released a May 2024 report outlining best practices for ethical AI use in clinical settings, recommending boards focus on physician accountability rather than regulating specific tools given rapid evolution.[77] The guidance urges documentation of AI inputs and overrides, risk assessments for algorithmic biases, and maintenance of the standard of care, informed by expert input on potential errors in diagnostics or treatment plans from unverified AI outputs.[78] FSMB's Technology Spotlight series further educates boards on emerging tech like blockchain for credentialing, aiming to balance innovation with patient safety.[79]Research and Data Resources
Physician Workforce Data and Censuses
The Federation of State Medical Boards (FSMB) maintains a national repository known as the Physician Data Center, which aggregates demographic, educational, licensure, and disciplinary information on physicians across the United States and the District of Columbia.[80] This data supports workforce analysis by tracking active licenses, enabling insights into supply, distribution, and trends in the physician population.[81] FSMB conducts a biennial census of licensed physicians, first formalized in recent decades to provide a comprehensive snapshot of the U.S. physician workforce.[82] The census compiles data from state medical boards, identifying all actively licensed physicians and documenting variables such as primary practice location, medical school origin (U.S. vs. international), degree type (MD vs. DO), gender, age, and licensure history.[81] It excludes inactive or revoked licenses, focusing on those enabling active practice, and accounts for physicians holding multiple state licenses—approximately 24% in recent years.[83] Results are published in the Journal of Medical Regulation and disseminated via FSMB reports, offering policymakers data for addressing shortages, geographic maldistribution, and specialty imbalances.[84] Key trends from the censuses highlight workforce expansion and demographic shifts. The 2024 census reported 1,082,187 actively licensed physicians, a 27% increase from 2010 levels, driven by growth in osteopathic physicians (DOs) and international medical graduates (IMGs).[84] U.S. medical graduates comprised 77% of the workforce, while IMGs accounted for 23%, reflecting ongoing reliance on foreign-trained physicians amid domestic training constraints.[85] Women represented nearly 40% of licensees, up from prior decades, and the mean age approached 52 years, indicating an aging cohort with implications for retirements and succession planning.[86]| Year | Actively Licensed Physicians | % Change from Prior Decade | Notes |
|---|---|---|---|
| 2010 | ~852,000 (implied) | - | Baseline for growth tracking.[84] |
| 2020 | 1,018,776 | +16% (MDs), +72% (DOs) | Total licenses: 1,442,454.[87] |
| 2022 | 1,044,734 | +23% since 2010 | 129,427 new licenses issued.[88] |
| 2024 | 1,082,187 | +27% since 2010 | 146,000 new licenses; physician-to-population ratio ~313 per 100,000.[85][84] |
