§485.638(a) Standard: Records System
(1) The CAH maintains a clinical records system in accordance with written policies
and procedures.
Interpretive Guidelines §485.638(a)(1)
The CAH must have a system of patient records, pertinent medical information, author
identification, and record maintenance that ensures the integrity of the authentication and
protects the security of all record entries. The medical record system must correctly
identify the author of every medical record entry. The medical record system must
protect the security of all medical record entries. The medical record system must ensure
that medical record entries are not lost, stolen, destroyed, altered, or reproduced in an
unauthorized manner. All locations where medical records are stored or maintained must
ensure the integrity, security and protection of the records.
The CAH must have a system in place that ensures that the identity of the author of each
entry is correct. The author of every entry must take a specified action to identify
himself/herself as the author (or responsible person) of the entry, the time and dating of
the entry, that the entry is accurate, and that he/she takes responsibility for accuracy of
the entry.
If the CAH uses computer entries there must be security system in place to ensure the
integrity of the record system, to ensure that the author of each entry is correctly
identified, to ensure that record entries are not altered or lost, that limits access to medical
records to only authorized persons, and ensures that records are not released to
unauthorized individuals. For the purposes of this regulation, electronic signatures
comply with those medical record entries that include a requirements for a signature.
There should be a current list of authenticated signatures, as well as a list of computer
codes and signature stamps (when used for authorship purposes) that have been
authorized by the governing body and are protected by adequate safeguards. CAH
policies and procedures should provide for appropriate sanctions for unauthorized or
improper use of computer codes or signature stamps.
The CAH must maintain a medical record for each inpatient and outpatient evaluated or
treated in any part or location of the CAH. A unit record for both inpatients and
outpatients may be used; however, when two different systems are used they must be
appropriately cross referenced. When a patient reimbursement status changes from acute
care services to swing bed services, a single medical record may be used for both stays as
long as the record is sectioned separately. Both sections must include admission and
discharge orders, progress notes, nursing notes, graphics, laboratory support documents,
any other pertinent documents, and discharge summaries.
The medical record must be properly filed and retained. The CAH must have a medical
recording system that ensures the prompt retrieval of any medical record, of any patient
evaluated or treated at any location of the CAH within the past 6 years.
The medical record must be accessible. The CAH must have a medical record system
that allows the medical record of any patient, inpatient or outpatient, evaluated and/or
treated at any location of the CAH within the past 6 years to be accessible by appropriate
staff, 24 hours a day, 7 days a week, whenever that medical record may be needed.
Survey Procedures §485.638(a)(1)
• Verify that a medical record is maintained for each person receiving care.
• Verify that written procedures ensure the integrity of authentication and protect
the security of patient records.
• Verify that medical records are stored and maintained in locations where the
records are secure, with protection from damage, flood, fire, theft, etc., and limits
access to only authorized individuals.
• Verify that records are accurate, completed promptly, easily retrieved and readily
accessible, as needed.
• Verify that there is an established system that addresses at least the following
activities of the medical records services:
o Timely processing and retrieval of records;
o Protecting the confidentiality of medical information;
o Compiling and retrieval of data of quality assurance activities.
• Verify that the system policies and procedures are reviewed and revised as
needed.
• Verify that the CAH employs adequate medical record personnel who possess
adequate education, skills, qualifications and experience to ensure the CAH
complies with requirements of the medical records regulations and other
appropriate Federal and State laws and regulations.
• Are medical records promptly completed in accordance with State law and CAH
policy?
• Select a sample of past patients of the CAH (inpatient and/or outpatient). Request
those patient’s medical records. Can the CAH promptly retrieve those records?
