The Pioneer: Dr. Mark H. Beers
The story of the Beers Criteria begins with a compassionate and dedicated geriatrician, Dr. Mark H. Beers. Born in Brooklyn in 1954, Dr. Beers became a leading expert in his field, deeply concerned with the quality of care for the most vulnerable older adults. In the late 1980s, while at Harvard University and the RAND Corporation, he conducted pioneering research focusing on medication use in nursing home residents. His studies, published in the Journal of the American Medical Association, revealed a troubling trend: many elderly patients were being prescribed psychoactive drugs and other medications that carried significant risks, often with limited benefit. This research laid the groundwork for a standardized approach to geriatric pharmacotherapy.
The Birth of the Original Criteria
Motivated by his findings, Dr. Beers gathered a panel of experts to create the first iteration of the Beers Criteria. Published in 1991, this initial list focused specifically on medications that were potentially inappropriate for older adults, particularly those residing in nursing homes. The criteria were revolutionary because they provided explicit guidance on which medications to avoid, offering clear, evidence-based direction for prescribers. Prior to this, decisions about medication appropriateness for seniors were often left to individual clinical judgment, without the benefit of a widely accepted, standardized tool. The original list brought much-needed clarity and a scientific framework to the complex issue of medication management in a population with unique physiological needs.
The Evolution of the Beers Criteria
Since its inception, the Beers Criteria has undergone numerous revisions and expansions to remain relevant with new medical evidence and changing clinical practices. The initial criteria were groundbreaking, but their scope was relatively narrow. Over time, the list was expanded to address a broader range of medications, health conditions, and care settings.
Transition to the AGS
In 2011, the American Geriatrics Society (AGS), a leading professional organization dedicated to improving the health of older adults, officially took over the maintenance and regular updating of the criteria. Since then, the list has been known as the AGS Beers Criteria®. This transition ensured that the guidelines would continue to be revised by a diverse, interprofessional panel of experts, including geriatricians, pharmacists, and other specialists, based on a rigorous review of the latest scientific evidence.
Updated Categories
Modern versions of the AGS Beers Criteria® are organized into five main categories, offering a comprehensive framework for medication review:
- Medications to avoid in most older adults.
- Medications to avoid in older adults with specific diseases or syndromes.
- Medications to be used with caution.
- Combinations of drugs that pose potentially inappropriate drug-drug interactions.
- Medications that require dosage adjustments based on kidney function.
How the Beers Criteria is Used in Practice
Healthcare providers use the Beers Criteria as a critical clinical tool to evaluate and optimize medication regimens for older adults. It serves as a starting point for discussion, guiding prescribers away from potentially harmful options and prompting consideration of safer alternatives. The criteria are never meant to be a rigid mandate, but rather a guide for informed clinical decision-making. Factors such as a patient's personal needs, health priorities, and the potential for deprescribing (safely reducing or discontinuing a medication) are always considered.
Risks Associated with Potentially Inappropriate Medications
Prescribing and using medications that appear on the Beers Criteria list can be associated with several risks for older adults. Their aging bodies process medications differently due to changes in metabolism and reduced organ function. Common risks include:
- Increased fall risk: Certain medications, like sedatives, can increase drowsiness and affect balance.
- Cognitive impairment: Some drugs can cause or worsen confusion, memory problems, and delirium.
- Adverse drug events (ADEs): Older adults are more susceptible to medication side effects, leading to higher rates of hospitalization and emergency room visits.
- Unnecessary complications: For older adults with specific health conditions, certain medications can exacerbate their symptoms.
Comparing Geriatric Medication Guidelines
While the Beers Criteria is widely recognized, other tools exist to help with geriatric medication management. Here is a comparison:
| Feature | Beers Criteria | STOPP/START Criteria | Deprescribing Guidelines |
|---|---|---|---|
| Focus | Lists medications to avoid (explicit criteria) | Lists criteria for appropriate and inappropriate prescribing | Provides a systematic process for tapering/discontinuing meds |
| Scope | Broad list of PIMs for most older adults | Includes both PIMs and prescribing omissions | Tailored to individual patient needs and goals of care |
| Audience | Clinicians, pharmacists, policymakers | Clinicians | Interdisciplinary teams (physicians, pharmacists, patients) |
| Goal | Reduce exposure to PIMs | Optimize prescribing, reduce errors | Minimize medication burden, reduce risk |
| Methodology | Expert panel, systematic review of evidence | Expert consensus, systematic review of evidence | Evidence-based, structured process |
The Lasting Legacy of Dr. Beers
Dr. Mark H. Beers, who passed away in 2009, left behind a legacy that continues to shape geriatric medicine. The criteria that bear his name have elevated the standard of care for millions of older adults by making medication safety a central consideration. Beyond its use as a clinical tool, the Beers Criteria has influenced policies and quality measures aimed at improving care. By promoting cautious and evidence-based prescribing, it has undoubtedly saved lives, prevented injuries, and enhanced the quality of life for the senior population. The work of Dr. Beers and the ongoing efforts of the American Geriatrics Society ensure that this vital resource remains a cornerstone of healthy aging for generations to come.

Conclusion: A Continued Commitment to Senior Health
The invention of the Beers Criteria by Dr. Mark H. Beers and his colleagues was a pivotal moment in the history of geriatric medicine. What began as a targeted effort to improve safety in nursing homes has grown into a powerful, internationally recognized tool that guides medication decisions across all care settings. The criteria's enduring impact highlights the importance of vigilance and patient-centered care when prescribing for older adults. As research continues to evolve, the American Geriatrics Society will ensure that this legacy remains relevant and effective, protecting the health and well-being of seniors everywhere.
