Respiratory Therapist Scope of Practice Regulations
This study addresses a gap in health economics literature by introducing a new dataset that documents state-level regulatory variations in the scope of practice for nine key respiratory therapist tasks, aiming to support future research in health policy and cardiopulmonary health.

In the complex machinery of modern healthcare, there are specialists who focus entirely on the breath. These professionals, known as respiratory therapists, are the experts who manage the breathing and heart-lung systems of patients, from newborns in intensive care to elderly individuals with chronic lung disease. Their work is vital; they operate the machines that keep people breathing when they cannot do so on their own, teach patients how to manage their conditions, and run tests to diagnose respiratory problems. However, the rules governing what these therapists are legally allowed to do vary significantly depending on where they work. In the United States, each state acts as its own regulator, deciding which specific tasks a therapist can perform, whether they need a doctor's direct order to act, and if they must be watched over by a physician while they work. These rules, known as scope of practice laws, are not just bureaucratic details; they determine how quickly a patient gets care, how hospitals are organized, and whether a community has enough qualified staff to handle emergencies.
For years, researchers and policymakers have understood how these rules affect doctors, nurses, and physician assistants, but the specific regulations for respiratory therapists remained largely undocumented in economic and health policy studies. A team of researchers from West Virginia University set out to fill this gap by creating the first comprehensive map of these rules across the entire country. They did not simply guess or rely on general summaries; instead, they systematically collected and verified the actual laws and regulations for all fifty states and the District of Columbia. Their work involved reading the specific legal codes written by state legislatures to determine exactly what a respiratory therapist is permitted to do in nine key areas of their job, such as applying treatments, assessing patients, and managing diseases. They then organized this information into a clear dataset that shows where the rules are strict, where they are flexible, and where they are simply unclear.
The researchers found that while the core medical tasks of respiratory therapy follow a somewhat predictable pattern, the details of who can do what and under whose supervision differ wildly from state to state. For the most common and critical activities—like applying breathing treatments, collecting diagnostic information, and assessing a patient's condition—most states allow therapists to perform these duties, but usually only if they have a doctor's authorization and are under a doctor's supervision. However, the map revealed unique exceptions. In Alaska, for instance, the state had not yet established a licensing system for these tasks at the time of the study, meaning the rules were effectively undefined. Pennsylvania stood out as the only state that allows therapists to perform these core tasks with either authorization or supervision, offering a slightly different path to care. In contrast, Georgia was the only state where the public records did not provide enough information to determine if therapists were even allowed to perform these essential duties.
As the researchers looked at more specialized areas of care, the patterns became even more varied. When it came to assessing how well a treatment was working, many states did not explicitly state the rules in their laws, leaving the interpretation to local hospital boards rather than clear state statutes. The rules for managing long-term diseases showed even more diversity; while most states followed the standard model, Arkansas and Pennsylvania allowed therapists to manage these conditions with either authorization or supervision, and Indiana was the only state that permitted therapists to manage disease without authorization, provided they were still under supervision. Perhaps the most distinct finding appeared in emergency care. Nebraska was the sole state that explicitly recognized that respiratory therapists could act independently during emergencies, granting them a level of authority that their counterparts in other states do not legally possess during a crisis.
The study also highlighted areas where the rules are often missing or inconsistent. When it comes to planning for a patient's discharge from the hospital or discussing end-of-life care, a large number of states do not state their policy at all, leaving these responsibilities in a legal gray area. Similarly, the rules for providing care through telehealth services are highly fragmented, with more than half of the states not stating their policy and the rest mostly requiring both authorization and supervision. The researchers noted that while their dataset provides a clear picture of the written laws, the actual practice in a hospital might be stricter, as individual facility boards can impose their own rules on top of state laws.
This new collection of data serves as a foundational tool for understanding how the legal environment shapes the delivery of breathing care. By laying out exactly what is allowed where, the researchers have provided a resource that can help others study whether these different rules affect patient outcomes, hospital quality, or the ability of communities to access care. The work does not claim to solve the problems of healthcare regulation, but it offers the first clear, systematic view of the landscape, showing that while respiratory therapists are essential everywhere, the legal framework that guides their hands is anything but uniform.
