Turning Your MLIS Into a Health Informatics Career

Health information technologist openings are projected to grow far faster than traditional librarian positions over the next decade, and healthcare systems are increasingly hiring outside clinical departments to fill them. For MLIS graduates, that shift matters: salaries in MLIS data science careers often outpace typical public or academic librarian pay by a wide margin, even for candidates without a computer science background.

The tension for most librarians considering this move is credential mismatch. A degree in library and information science teaches metadata, classification, and information governance, but few programs label those skills as "informatics" outright, leaving graduates unsure whether they qualify for clinical data roles or need additional certification first.

That uncertainty is exactly what keeps otherwise qualified candidates out of a growing, better-paying field.

What Is Health Informatics (And How It Differs From Health Librarianship)

Defining Health Informatics

Health informatics sits at the intersection of information science, computer science, and healthcare. It focuses on how data is collected, stored, analyzed, and used to improve patient outcomes and make healthcare systems more efficient. Practitioners in this field design and manage electronic health records (EHRs), develop clinical decision support tools, and ensure that health data flows securely between providers, insurers, and patients. As hospitals and clinics shift toward value-based care, the demand for skills in data analytics and system interoperability continues to grow. Programs like Liberty University's online BS in Healthcare Informatics point to the rising need for professionals who understand both the technology and the healthcare environment.

Health Informatics vs. Health Information Management

People often confuse health informatics with health information management (HIM), but they serve different functions. HIM concentrates on the administrative side: medical coding, billing, compliance with privacy regulations, and the day-to-day management of patient records. Health informatics, on the other hand, deals more with the design and optimization of the information systems themselves. An HIM professional might ensure that a hospital's coding procedures are accurate, while a health informatics specialist would build or tweak the EHR system to speed up that coding workflow and reduce errors.

How It Differs from Health Librarianship

Health librarianship is another related field that MLIS graduates often enter (our guide on how to become a medical librarian outlines the credentialing process), but it has a distinct focus. Health librarians work in hospitals, academic medical centers, or public libraries to connect patients and clinicians with evidence-based health information. They teach health literacy, curate consumer health resources, and support research. While health informatics also involves information organization, it is more technical and systems-oriented. Health librarians may guide a nurse to the latest clinical trial data; a health informatics professional would build the search interface or integrate that data feed into the electronic health record. MLIS graduates can thrive in any of these areas, but moving into health informatics typically demands additional technical training, such as python for librarians, database management, or health data standards like HL7 and FHIR.

Where MLIS Skills Fit

For library and information science professionals, health informatics represents a natural expansion of mlis career pathways. Core competencies in metadata, classification, user-centered design, and information retrieval translate directly to clinical data management and health IT projects. The ability to bridge people and technology is especially valuable as healthcare organizations grapple with interoperability challenges and growing volumes of patient-generated data. An MLIS degree, bolstered by certifications or hands-on experience with health databases, can open doors to roles that shape how health information is captured, shared, and used.

How MLIS Skills Transfer to Health Informatics Work

Can the skills from a library science degree really prepare you for a career in health informatics?

The Shared Core: Organizing Information for Impact

MLIS programs train students to organize, classify, and retrieve information efficiently, core skills you learn in mls program that directly apply to health informatics. Managing electronic health records (EHRs), developing metadata schemas for clinical data repositories, and designing taxonomies for medical literature all build on these LIS competencies. For example, an informatics librarian might create controlled vocabularies that improve search accuracy within a hospital’s patient data system, directly applying cataloging principles.

From User Research to Health System Design

User-centered research methods, a core part of mlis skills for ux research, translate seamlessly to healthcare settings. Understanding how clinicians, patients, and administrators interact with information systems allows MLIS professionals to design interfaces that reduce errors and improve decision-making. This might involve usability testing of a telehealth platform or analyzing workflows to streamline access to clinical guidelines. Program evaluators often note that MLIS graduates bring a unique blend of empathy and analytical rigor to these tasks.

Data Curation and Governance in a Clinical Context

Data curation , the selecting, preserving, and maintaining of digital assets , is second nature to librarians, and the basis of digital asset management MLIS work. In health informatics, this becomes data governance: ensuring patient data is accurate, secure, and compliant with regulations like HIPAA. MLIS graduates skilled in metadata and information policy can lead initiatives such as building data dictionaries for hospital networks or implementing data quality standards across research databases.

Bridging the Clinical Knowledge Gap

While the foundational skills are strong, MLIS graduates often need supplemental knowledge in medical terminology, clinical workflows, or healthcare IT systems. Programs like Liberty University’s online BS in Healthcare Informatics illustrate how coursework in data security, medical coding, and pharmacy terminology can fill this gap.¹ Though targeted at undergraduates, this interdisciplinary model underscores the potential for MLIS graduates to layer clinical knowledge onto their established information skills. For library science professionals, pursuing a graduate certificate in health informatics or on-the-job training can provide the necessary clinical context to complement their information expertise.

Job Titles and Salary Data for Mlis-Informatics Roles

The two Bureau of Labor Statistics occupations most closely aligned with health informatics work for MLIS graduates are Health Information Technologists and Medical Registrars and Medical Records Specialists. The table below draws on 2024 national data from the Occupational Employment and Wage Statistics survey published by the U.S. Bureau of Labor Statistics. These figures represent all workers in each occupation, not only those holding an MLIS. Graduates who specialize in clinical informatics or earn a dual degree (such as an MLIS combined with a Master of Health Informatics) often command salaries above these medians, particularly at the 75th percentile and beyond.

Health Informatics Salaries by State: Where MLIS Graduates Earn the Most

Salaries for health information technologists and medical registrars vary widely by state, shaped by local cost of living, concentration of healthcare systems, and workforce demand. The table below ranks the top five highest-paying states alongside a selection of other notable markets. Data is drawn from the Occupational Employment and Wage Statistics program (2024) published by the U.S. Bureau of Labor Statistics. States like California and Massachusetts offer top-tier pay but also carry significantly higher living costs, so net purchasing power may be closer to what lower-cost states provide. Meanwhile, employment totals reflect each state's population and density of healthcare hubs: California employs roughly 3,270 workers in this category compared to just 40 in Wyoming, underscoring how job availability differs as much as compensation.

Top-Paying Metro Areas for Health Informatics Jobs

Metro areas anchored by major medical centers and large hospital networks consistently offer both higher pay and greater job availability for health informatics professionals. The table below highlights median salaries for health information technologists and medical records specialists across leading metros, based on 2024 data from the Bureau of Labor Statistics Occupational Employment and Wage Statistics program. In several of these metros, median pay runs well above the corresponding state average, reflecting the concentration of academic medical centers, health systems, and research institutions that drive demand for informatics talent.

Certifications and Skills That Strengthen an MLIS for Health Informatics

A certification is what turns an MLIS degree into a credible health informatics candidate rather than a curious outsider. Employers screening resumes for informatics roles routinely look for a handful of specific credentials, and holding one signals that a librarian's skills translate into healthcare data work without requiring on-the-job retraining.

The Credentials Employers Ask For

Job postings in 2026 most frequently mention CPHIMS, RHIA, CHDA, and CAHIMS, according to healthcare IT job listings analyzed by Indeed and others.¹

• CPHIMS (HIMSS): The most popular credential among experienced digital health professionals. It has three eligibility tiers based on degree level, generally requiring three to five years of work experience and one to three years of healthcare-specific experience. Exam fees run from roughly $529 to $699, with retakes around $339 and renewal fees between $339 and $459.²
• CAHIMS (HIMSS): An entry-level counterpart to CPHIMS, now open to anyone with a high school diploma. It's often preferred rather than required, making it a reasonable first step for MLIS grads still building healthcare experience.³
• RHIA (AHIMA): A rigorous credential requiring graduation from a CAHIIM-accredited health information management or informatics program. The exam runs four hours across 180 questions, with renewal every two years. A standalone MLIS typically doesn't qualify; a joint program or post-MLIS certificate usually bridges the gap.⁴
• CHDA (AHIMA): Focused on health data analytics, generally requiring a CAHIIM-accredited master's degree.¹ The exam takes three and a half hours and is described by AHIMA as one of the most valuable credentials for analytics-track roles.⁵
• AHIC (AMIA): A newer, practice-based credential for those already working in operational informatics roles. It's less common but gaining traction for advanced positions.⁶

AHIMA credentials, in particular, carry a reputation as the most recognized by employers across health information roles.¹

Planning Around Eligibility Gaps

Because RHIA and CHDA lean on CAHIIM accreditation, MLIS graduates without a joint degree often need a bridge. Graduate certificates in health informatics, offered through programs like Northwestern's, exist specifically to fill that gap and open the door to certification exams later.⁸

Pairing Credentials with the Degree

None of these certifications replace an MLIS; they extend it. A librarian who pairs an MLIS with CPHIMS or a health informatics graduate certificate, such as through a joint MLIS degree program like University of Wisconsin-Milwaukee's health care informatics and library science track, presents a far stronger case to hiring managers than a degree alone.⁷

Ala-Accredited MLIS Programs With Health Informatics Tracks or Dual Degrees

Several ALA-accredited MLIS programs now offer structured pathways into health informatics, ranging from formal concentrations and dual degrees to curated elective sequences and practicum placements in health sciences settings. ALA accreditation matters because many employer-funded positions in academic medical centers, hospital libraries, and federal health agencies require a degree from an ALA-accredited program. Students who pursue a dual degree or formal concentration often move into senior informatics roles faster, since they graduate with both the information science foundation and the domain-specific health data expertise that hiring committees look for.

Career Path Progression: From Librarian to Health Informatics Specialist

Moving from a health sciences librarian role into health informatics isn’t just a lateral move; it’s a deliberate shift toward higher earning potential and broader scope. While traditional mlis career pathways offer modest step increases, informatics-aligned roles can command pay premiums of 30% or more¹ at the same experience level. The path below maps one common progression, though timing varies by institution type and whether your title is classified as librarian or IT staff.

Entry Level: Health Sciences Librarian (0, 3 Years)

Most professionals start with an ALA-accredited MLIS in a hospital, academic medical center, or public health library. Responsibilities center on reference, evidence-based practice support, and collection management. National salary bands for these roles fall between $48,000 and $60,000¹, though positions with explicit informatics duties in larger health systems sometimes push the range to $55,000 to $70,000. This stage builds foundational domain knowledge: medical terminology, clinical workflows, and research data management.

Mid-Career: Clinical Informatics Specialist (4, 7 Years)

After two to four years, those who add a graduate certificate in health informatics (often through an online mlis informatics programs) or substantial systems experience can step into a Clinical Informatics Specialist or Clinical Informatics Librarian title. Here the focus shifts to clinical decision support tools, electronic health record optimization, and user-centered data systems. Salaries grow significantly, typically landing between $75,000 and $95,000 nationally¹. That’s notably higher than the standard mid-career librarian band of $60,000 to $75,000¹, reflecting the hybrid skill set. At this stage, professionals often join informatics teams rather than the library department, which can accelerate career velocity.

Senior: Director of Clinical Informatics (10, 15+ Years)

Reaching a director-level role requires at least a decade of progressive experience, often in academic medical centers with clear rank structures. Credentials frequently include a second master’s , an MS in Health Informatics, MPH, MHA, or MBA , along with demonstrated leadership in clinical data governance or enterprise informatics strategy. Compensation ranges from $110,000 to $150,000¹, with the upper end common in large health systems and high-cost metros. In contrast, senior librarians on a traditional track may top out nearer to $95,000¹, making the informatics path a powerful lever for long-term earning growth.

Accelerating the Progression

Stacking a dual mlis ma degree or certification early can compress the timeline. An MS in Health Informatics earned concurrently with an MLIS, or certifications like AHIMA’s RHIA or AMIA’s Clinical Informatics Board eligibility, can open mid-career roles in as little as two years post-graduation. Similarly, choosing an employer that classifies you as an IT professional rather than a librarian often leads to higher salary bands from day one².

Job Search Strategies: Where MLIS Grads Get Hired

Where are health informatics jobs actually growing, and how does that compare to the traditional librarian market? Federal labor projections point to health information roles expanding much faster than librarian positions. The Bureau of Labor Statistics projects Health Information Technologists and Medical Registrars to grow between 15%² and 16.3%¹ from the early 2020s through the mid-2030s, adding thousands of new positions¹ and ranking among the fastest-growing occupations tracked nationally.¹ Librarian and library media specialist roles, by contrast, have historically shown slower, closer-to-average growth in prior BLS releases. That gap is exactly why MLIS graduates are looking toward health informatics as a career extension rather than a detour.

Who Is Hiring

Health informatics employers span several distinct settings, each with different hiring patterns:

• Hospitals: The largest single employer of health information professionals³, though overall hospital job growth is comparatively moderate.⁴
• Academic medical centers: Often counted within hospital employment data, these institutions blend clinical care with research and teaching, creating demand for information specialists who can manage both patient records and research data.
• Ambulatory care and physician offices: This segment is projected to add the largest share of new healthcare jobs nationally, outpacing hospital growth by a wide margin.⁴ It is an area worth watching closely for MLIS grads entering the field.
• Public health agencies, insurers, and health IT vendors: These niches lack dedicated federal projections but represent steady, specialized demand for people who can organize, secure, and interpret health data.
• Consulting firms: Increasingly hire information professionals to help healthcare clients implement and troubleshoot data systems.

Building the Right Network and Materials

Professional associations matter here: while library associations for MLIS students serve the broader field, health-specific groups like AMIA (the American Medical Informatics Association) and HIMSS (Healthcare Information and Management Systems Society) host conferences, local chapters, and mentorship programs where MLIS grads meet hiring managers directly. Tailoring a resume to health informatics terminology, referencing electronic health record systems, data governance, or clinical terminology standards rather than purely library jargon, helps applications clear automated screening tools.

Internships or practicum placements in hospital informatics departments or public health agencies give MLIS students hands-on credibility before graduation. For active job searching, the MLA (Medical Library Association) Career Center and HIMSS JobMine are two boards specifically built for this crossover audience, often listing roles that never appear on general library job sites; still, the broader library hiring trends 2026 are worth tracking for MLIS graduates.
