Final answer:
An OTR/L seeking to improve client care at a private clinic would most likely utilize the Patient Protection and Affordable Care Act (PPACA) or Obamacare, as it is designed to increase access to healthcare and improve the quality and affordability of healthcare services.
Step-by-step explanation:
An OTR/L (Occupational Therapist, Registered/Licensed) working to improve client care in a private clinic would be most interested in using the Patient Protection and Affordable Care Act (PPACA), also known as Obamacare. This legislation, signed into law in March of 2010, was designed to provide all Americans with access to affordable health insurance, mandate that everyone in the United States acquires some form of health insurance, and aim to lower the costs of healthcare overall. Since the OTR/L is looking to improve quality, client satisfaction, and client outcomes, the Affordable Care Act would be the most applicable legislation because it directly impacts healthcare delivery and the availability of services for patients.
