§485.635(a)(3) [The policies include the following:]
(v) Procedures for reporting adverse drug reactions and errors in the
administration of drugs.
Interpretive Guidelines §485.635(a)(3)(v)
CAH staff must report all drug (medication) administration errors and all adverse drug
reactions. This required reporting includes two distinct steps in the reporting of drug
(medication) administration errors and adverse drug reactions. The first and highest
priority reporting relates to the care of the patient, at time of occurrence. The second
reporting step is related to the CAH-wide Quality Assurance review as addressed in
§485.641(b).
Medication administration error:
The National Coordinating Council Medication Error Reporting and Prevention
definition of a medication error is “Any preventable event that may cause or lead to
inappropriate medication use or patient harm while the medication is in the control of
the health care professional, patient, or consumer. Such events may be related to
professional practice, health care products, procedures, and systems, including
prescribing; order communication; product labeling, packaging, and nomenclature;
compounding; dispensing; distribution; administration; education; monitoring; and
use.” A medication administration error is one that occurs in the phase of the
medication process where the drug actually enters the patient by one of various
possible routes, e.g., orally, intravenously, etc.
• Adverse drug reaction:
The American Society of Health-System Pharmacists (ASHP) defines an adverse
drug reaction (ADR) as “Any unexpected, unintended, undesired, or excessive
response to a drug that:
1. Requires discontinuing the drug (therapeutic or diagnostic)
2. Requires changing the drug therapy
3. Requires modifying the dose (except for minor dosage adjustments)
4. Necessitates admission to a hospital
5. Prolongs stay in a health care facility
6. Necessitates supportive treatment
7. Significantly complicates diagnosis
8. Negatively affects prognosis, or
9. Results in temporary or permanent harm, disability, or death.
Consistent with the definition, an allergic reaction (an immunologic hypersensitivity
occurring as the result of unusual sensitivity to a drug) and an idiosyncratic reaction
(an abnormal susceptibility to a drug that is peculiar to the individual) are also
considered ADRs.”
Patient Care
In the case of ADRs or medication administration errors that are not caught before they
reach the patient, a “report” must be made to a practitioner responsible for the care of the
patient.
For example, if a medication actually is administered to a patient when it should not
be, or the wrong dose is administered, or the wrong route of administration is used,
etc., or a medication that should have been administered to the patient has not been
administered in a timely manner, then the medication administration error has reached
the patient and must be reported to the responsible practitioner.
If, on the other hand the wrong dose of a drug is prepared for a patient, but a nurse
catches this and does not give that dose to the patient, then a medication
administration error has occurred, but the error has not reached the patient, and thus
does not need to be reported to the responsible practitioner.
Not every medication administration error that reaches the patient causes harm or has the
potential to cause harm; it depends both on the drug and on the patient’s condition.
In the case of all ADRs and any medication administration error that has harmed or has
reached the patient and could potentially cause harm, the report to a practitioner must be
made immediately after the staff identify the adverse reaction or (potentially) harmful
error, to enable a timely assessment and intervention. The report must be made directly
in a manner that confirms a practitioner received the report, for example, via a phone call.
If the impact of the medication error that reached a patient is unknown, the error must be
reported to a practitioner immediately. Documentation of the error or reaction, including
notification to the practitioner, must be in the patient’s medical record.
Medication administration errors that have reached the patient but result in no harm and
do not have the potential to cause harm can be reported to a practitioner during usual
working hours. For example, if an over-the counter analgesic dose is missed during the
night shift, it can be reported first thing in the morning as no further intervention would
be required by the practitioner. CAHs should provide clinical staff with expected
guidance on how to respond to these situations.
Quality Assurance/Improvement Reporting:
Reduction of medication administration errors and ADRs may be facilitated by effective
internal CAH reporting that can be used to assess vulnerabilities in the medication
process and implement corrective actions to reduce or prevent reoccurrences. To facilitate
reporting, the CAH must educate staff on medication administration errors and ADRs
including the criteria for those errors and ADRs that are to be reported for quality
assurance/improvement purposes, and how, to whom and when they should be reported.
Reporting for quality assurance/improvement purposes covers all identified medication
errors, regardless of whether or not they reach the patient, and those ADRs meeting the
criteria specified in the CAH’s policies.
For Information Only - Not Required/Not to be Cited
To improve staff willingness to report medication errors and ADR incidents, CAHs are
encouraged to adopt a non-punitive approach that focuses on system issues rather than
individual health care professionals. A non-punitive approach is likely to encourage
reporting by those who otherwise may fear retribution or CAH disciplinary action.
In addition to internal staff reporting, the CAH is expected to take other steps to identify
medication administration errors and ADRs. Reliance solely on staff-generated incident
reporting fails to identify the majority of adverse drug events. Proactive identification
includes observation of medication passes, concurrent and retrospective review of
patient’s clinical records, implementation of medication usage evaluations for high-alert
drugs, and identification of indicator drugs that, when ordered, automatically generate a
drug regimen review for a potential adverse drug event.
The CAH must assess the effectiveness of its internal reporting system to determine
whether or not it is identifying as many medication errors and ADRs that would be
expected for the size and scope of services provided by the CAH. In making such
assessments the CAH could refer to established benchmarks or studies on error or ADR
rates published in peer-reviewed journals.
For Information Only – Not Required/Not to be Cited
CAHs are encouraged to participate in state-wide and national patient safety
organizations for reporting of drug administration errors, ADRs, and drug
incompatibilities. National organizations include, but are not limited to, the FDA
MedWatch Reporting Program and the Institute for Safe Medication Practices (ISMP)
Medication Errors Reporting Program. These organizations, along with other patient
safety organizations, collect and analyze data, identify trends, and provide feedback
and recommendations to health care organizations to reduce the risk of medication
related errors and events.
Survey Procedures §485.635(a)(3)(v)
• Assess whether the CAH ensures that medication administration errors and ADRs are
reported to practitioners in a timely manner.
o Are nursing staff familiar with the concepts of medication errors that do and
do not reach the patient, as well as ADRs?
o Ask nursing staff what they would do in the case of a medication
administration error that reaches the patient or an adverse drug event.
o Ask nursing staff if they can provide examples of cases where they needed to
report an ADR. Is the report to the practitioner documented in the medical
record?
o Review records of medication errors and ADRs to determine that they are
reported immediately in accordance with written procedures, and that
medications administered and/or drug reactions are promptly recorded in the
patient’s medical record.
• Can the CAH demonstrate that it has a system for reporting/identifying ADRs and
medication administration errors for quality assurance/improvement purposes?
• Interview CAH staff (nursing, pharmacy and medicine) to ascertain awareness of the
CAH’s policy on reporting medication administration errors and ADRs for quality
improvement purposes
• Does the CAH have evidence of training staff on reporting expectations?
• Does the CAH rely only upon internal staff incident reporting or does it use other
methods to identify potential/actual medication errors and ADRs, as well?
Ask the individual responsible for the QA program to demonstrate how the CAH
determines if the number of medication administration errors and ADRs reported is
consistent with the size and scope of services provided by the CAH.
• Review QA activities for medication administration errors and ADRs to
determine if, upon analyses of the reports, potential corrective actions are
identified and implemented, if appropriate.
