Health Professions Regulation in the US

The Impact of Scope of Practice

A key goal of health reform in the US is to improve population health through expanded access to health insurance. Demand for high-quality, cost-effective, basic health services is anticipated to grow, particularly for underserved populations. However, there is also growing concern about the impact of health professions scope of practice on access, quality, and cost of health services. Since health professions regulation falls under state jurisdiction, the legal scope of practice for a health profession is typically defined in a state-specific scope of practice act. These acts describe the services that professionals can provide and under what conditions they can be provided. Scope of practice acts also define the requirements for education and training, certification and licensure, and supervision. Restrictive legal scopes of practice often serve as a barrier to effective and efficient delivery of health services.

Key Issues and Challenges Related to Scope of Practice Regulation

Legal Scope of Practice vs Professional Scope of Practice or Competence

  • While a health professional may be trained and competent to provide a service, a restrictive legal scope of practice in a state may prohibit him/her from providing a service in that state
  • Legal scope of practice and professional competence overlap, and the amount of overlap varies by state and by profession (eg, state-to-state scope of practice variation for nurse practitioners)

Overly Restrictive Scope of Practice for a Profession Can Limit Patients’ Access to Care

  • When a service can only be provided by a more highly skilled professional, it can increase the cost of that service (eg, a nurse can immunize a patient while a medical assistant cannot)

Lack of Consistency in Scope of Practice Across States

  • Limits professional mobility
  • Challenging for multistate health care provider organizations and providers of telehealth services that cross state lines

Changing Existing Scope of Practice Regulations for a Profession Is Often a Costly, Time-consuming, Adversarial, and Incremental Process Involving Many Stakeholders With Divergent Opinions About the Proposed Change/s

  • Although the primary purpose of scope of practice regulation is to protect public safety, efforts to change scope of practice requirements often include an element of professional self-interest from professions that already perform a task or provide a service

Policy Reforms to Support Improvements in Scope of Practice Decision Making

  • Aligning profession-specific legal scopes of practice with professional competence
  • Increasing participation of consumers in scope of practice decision making
  • Using the best available evidence about what is best for patients in scope of practice decision making
  • Allowing short-term demonstration/pilot programs that are carefully evaluated to test new approaches when evidence is not available
  • Establishing a national clearinghouse on scope of practice information and research with up-to-date and reliable information on scope of practice proposals, modifications, demonstrations, innovations, evaluations, and model practice acts
