Recognizing Red Flags: Early Warning Signs of Impairment, Diversion & Risk in Healthcare Settings

The behavioral, physical, and clinical signs that often appear before diversion is confirmed, and why staff need to know what to look for.

Drug diversion in healthcare settings rarely announces itself. It shows up first as small, easy-to-dismiss changes: a coworker who seems tired more often, a shift where the count is off by one, a patient who says their pain isn't controlled. On their own, these signs can look unremarkable. Together, these signs may form a broader pattern that staff should know how to recognize and evaluate within their facility's established policies.

Section 1

Behavioral Changes

Changes in mood, attention, and presence at work are often the first signs noticed by coworkers.

Confusion or Memory Lapses

Difficulty concentrating, confusion, or memory lapses that are inconsistent with someone's usual performance.

Lethargy at Work

Noticeable tiredness or falling asleep during shifts.

Sudden Mood Swings

Productivity that fluctuates wildly, paired with unexplained changes in mood.

Unexplained Absences

Frequent or unexplained absences, including sick days, extended bathroom breaks, or disappearances during a shift.

Increased Secrecy

Becoming increasingly secretive or withdrawing from the team.

Unusual Dress

Wearing long sleeves unexpectedly, which can be used to conceal physical signs.

Section 2

Physical Indicators

Physical signs are often more visible in the moment but easier to attribute to something else, which is exactly why they're worth paying attention to as part of a broader pattern.

Tremors or Slurred Speech

Noticeable shakiness, tremors, or slurred speech.

Decline in Appearance

A decline in grooming or personal appearance compared to someone's baseline.

Section 3

Unusual Workplace Behavior

Diversion often involves patterns around how someone interacts with controlled substances specifically, not just how they behave generally.

Excessive Time With Controlled Substances

Spending an unusual amount of time handling controlled substances relative to their role.

Volunteering for Access

Frequently volunteering for inventory, restocking, or dose retrieval duties.

Vial Count Discrepancies

Often returning an incorrect number of vials at the end of a shift.

Unaccounted-For Time

Not being where they say they will be during a shift.

Section 4

Clinical & Procedural Concerns

Some of the clearest signs of diversion show up in clinical documentation and patient outcomes, not just staff behavior.

Inappropriately Large Doses

Administering doses that are inappropriately large for the patient or procedure.

Patient Pain Complaints

Frequent patient complaints of poor pain control despite documented administration.

Unexplained Usage Spikes

Unexplained spikes in controlled substance usage across all patients, not just one.

Drugs Found in Improper Areas

Drugs or empty vials found in improper areas, such as trash or restrooms.
