Final answer:
Computerized medical records are filed under both the client's last name and a unique client number, referred to as option (D) 'B and C'. The use of these records seeks to improve healthcare while ensuring patient privacy.
Step-by-step explanation:
Computerized medical records, also known as electronic health records (EHRs) or electronic medical records (EMRs), are typically filed under both the client's last name and a unique client number. This dual method ensures that information can be accurately retrieved and that patient privacy is maintained. Option (D) 'B and C' is correct as it refers to filing under both the last name and the client number.
The use of these digital records among health providers is a crucial step towards enhancing the efficiency and quality of health care services. Their structured filing system makes it possible for authorized personnel to share patient data securely, aiming to improve care coordination and reduce healthcare costs. However, the privacy of electronic records is essential, considering various regulations like the Health Insurance Portability and Accountability Act (HIPAA) that protect patient information.
