MODULE 30: OVERRIDE & BEDSIDE REALITIES
Section 30.1: Pyxis/Omnicell Override Etiquette: When It’s OK, and When It’s Not
Mastering one of the highest-risk decisions in hospital pharmacy: navigating the ethics and safety of bypassing the pharmacist’s review.
SECTION 30.1
Pyxis/Omnicell Override Etiquette
Balancing the need for speed with the mandate for safety.
30.1.1 The “Glass Case”: Understanding the Power and Peril of the Override
In every high-stakes environment, there is an emergency override. It’s the red “break glass in case of emergency” fire alarm box on the wall, the emergency stop button on an assembly line, the manual override for an airplane’s autopilot. These mechanisms exist for a single reason: to bypass standard operating procedures when those procedures are too slow to respond to a life-threatening crisis. The ability for a nurse to override an Automated Dispensing Cabinet (ADC) like a Pyxis or Omnicell is pharmacy’s version of that glass case. It is a powerful, necessary, and exceptionally dangerous tool.
To understand the risk, you must first appreciate the safety net that an override intentionally cuts. The standard medication workflow is a masterpiece of safety engineering, with each step designed to catch potential errors. The physician enters an order, but it is held in a pending state. The pharmacist—a second, highly trained clinician with a different perspective—then performs a meticulous review. They check the dose, the indication, the patient’s allergies, their organ function, and potential drug interactions. Only after this independent double-check is the medication “released” and made available to the nurse in the ADC. The override function takes a sledgehammer to this entire process. It allows a medication to be pulled from the machine and administered to a patient before any pharmacist has ever laid eyes on the order.
The Override as a Safety Inversion
The standard workflow is designed to prevent errors before they reach the patient. The override workflow, by its very nature, allows a potential error to reach the patient’s bedside immediately. The safety process is inverted: instead of prospective prevention, we are left with only retrospective review. This is why the decision to use, or approve the use of, an override is one of the most critical judgments a nurse and pharmacist can make. It is an explicit acceptance of a higher level of risk, and it must be reserved for situations where the risk of delay is unequivocally greater than the risk of an unreviewed order.
Standard Workflow vs. Override Workflow: The Bypassed Safety Checks
| Safety Step | Standard (Profiled) Workflow | Override Workflow |
|---|---|---|
| Order Entry | Physician enters an order into the EHR. | Medication is removed from the ADC *before* a formal order may exist. |
| Pharmacist Verification | Pharmacist performs a full clinical review:
|
ENTIRE STEP IS BYPASSED. None of these safety checks are performed by a pharmacist prior to medication availability. |
| Medication Availability | Medication becomes available for withdrawal from the ADC *only after* pharmacist verification. | Medication is available for immediate withdrawal by a nurse selecting the “override” function. |
| Administration | Nurse administers a pharmacist-reviewed medication. | Nurse administers a medication that has not been reviewed by a pharmacist. |
| Pharmacist Review | Prospective (before administration). | Retrospective (after administration). The pharmacist only reviews the override report later to “clean up” the record, long after the drug has been given. |
30.1.2 The Justifiable Override: A Masterclass in True Emergencies
The list of situations that justify an override is exceptionally short. A justifiable override is always linked to a sudden, life-threatening clinical deterioration where a delay of even a few minutes to wait for pharmacist verification could lead to irreversible patient harm or death. These are the “Code Blue” moments of medication administration. As a pharmacist, you must know these scenarios by heart, not to approve them in real-time (as they are happening too fast), but to recognize them as appropriate when you perform your retrospective review.
The Litmus Test for a Justifiable Override
Ask yourself this question: “Is there a reasonable chance the patient will die or suffer severe, irreversible harm in the next 5-10 minutes if this medication is not administered immediately?” If the answer is an unequivocal “yes,” then an override is likely justified. If the answer is “no,” “maybe,” or “it would be inconvenient,” then an override is not appropriate.
Masterclass Table of Justifiable Override Scenarios
This table details the rare clinical emergencies where bypassing the pharmacist is the correct and expected standard of care.
| Emergency Scenario | Clinical Description & Rationale for Speed | Common Medications Pulled on Override | Pharmacist’s Retrospective Role |
|---|---|---|---|
| Cardiopulmonary Arrest (“Code Blue”) | The patient has no pulse and is not breathing. This is the ultimate medical emergency. Medications from the crash cart or ADC must be given within seconds based on ACLS algorithms. There is zero time for order entry or verification. |
|
After the code is over, your job is to reconcile the code record with the patient’s chart. You ensure a physician enters retrospective orders for every medication that was administered, linking them to the override transaction. |
| Rapid Sequence Intubation (RSI) | The patient is in acute respiratory failure and must be emergently intubated to secure their airway. A specific sequence of sedatives and paralytics must be given in rapid succession to facilitate the procedure safely. Delay could lead to hypoxia and brain death. |
|
Similar to a code blue, you will retrospectively review the override and ensure a physician has entered the appropriate orders for the RSI medications. You also ensure the paralytic is not continued as a scheduled infusion by mistake. |
| Status Epilepticus / Active Seizure | A patient is having a prolonged seizure (>5 minutes) that is not stopping. Every second of seizure activity increases the risk of permanent neuronal damage. Emergent administration of a benzodiazepine is the first-line treatment. |
|
Review the override to ensure the dose was appropriate. Ensure a formal order is entered. Assess if the patient needs scheduled antiepileptic therapy to be ordered to prevent recurrence. |
| Acute, Severe Hypoglycemia with Altered Mental Status | A patient’s blood sugar is critically low (e.g., <40 mg/dL) and they are unconscious, confused, or seizing, and unable to take oral glucose. IV dextrose is a life-saving intervention that must be given immediately to prevent brain damage. |
|
Review the override. Ensure a physician enters the order. Most importantly, investigate the *cause* of the hypoglycemia. Was an antidiabetic agent dosed incorrectly? Your role shifts to preventing the next episode. |
| Sudden, Severe Agitation with Danger to Self or Staff | A patient develops acute, violent delirium or psychosis and is an immediate physical danger to themselves or the healthcare team. A chemical restraint (an emergent antipsychotic or benzodiazepine) is needed to de-escalate the situation safely. |
|
Review the override to ensure it aligns with hospital policy for chemical restraints. Ensure the order is entered and that the underlying cause of the agitation is being investigated (e.g., delirium, substance withdrawal). |
30.1.3 The Unjustifiable Override: A Masterclass in Resisting Convenience
The vast majority of override requests you will encounter in your daily practice are not for the true emergencies listed above. They are driven by a desire for speed, a frustration with perceived delays, or a misunderstanding of the risks involved. These are the moments where your role as a safety gatekeeper is most critical. Your job is to politely, professionally, and firmly say “no” to the override while simultaneously demonstrating your value by rapidly solving the underlying problem that led to the request.
The Art of the “Yes, and…” Response
Never start your response to an inappropriate override request with a flat “No.” This creates an adversarial dynamic. Instead, use a collaborative “Yes, and…” approach.
Nurse: “I need to override the morphine, the patient is in severe pain and I don’t see it on their profile.”
Your Response: “Yes, I agree we need to get your patient pain medication immediately, and for their safety, I need to verify the order first before it can be pulled. I see the order in my queue right now and I am verifying it as we speak. It will be available on the patient’s profile in less than 30 seconds.”
This technique validates the nurse’s concern (the “Yes”), reaffirms the safety standard (the “and”), and provides an immediate solution. You have enforced the policy without creating a conflict.
Masterclass Table of Unjustifiable Override Scenarios & The Pharmacist’s Playbook
This table details common but inappropriate override requests and provides a step-by-step guide on how to manage them effectively.
| The Scenario & Nurse’s Rationale | The Hidden Safety Risks | The Pharmacist’s Step-by-Step Playbook |
|---|---|---|
| “The order is in, but it’s not showing up. Pharmacy is too slow.”
Rationale: The nurse sees a new order and wants to act on it immediately, but it’s not yet profiled in the ADC. They believe the delay is purely administrative. |
|
|
| “It’s just a routine PRN.”
Rationale: The nurse perceives the medication as low-risk (e.g., acetaminophen, ondansetron) and believes verification is a formality that can be skipped for patient comfort. |
|
|
| “The doctor is standing right here and told me to get it.”
Rationale: The nurse is under direct pressure from a physician and feels caught in the middle. They are using the physician’s presence as justification for the override. |
|
|
| “It’s just a saline flush / sterile water.”
Rationale: The nurse views these as supplies, not medications, and doesn’t understand why a pharmacist’s review is needed. Accessing them from the override menu is seen as a simple workflow shortcut. |

30.1.4 Retail Pharmacist Analogy: The “Doctor Said It Was Okay” Refill
A Deep Dive into the Analogy
You have navigated the high-stakes pressure of an inappropriate override request thousands of times in your retail career. The scenario is different, but the core conflict—balancing patient demand against your professional duty to follow safety procedures—is identical.
The Scenario:
A patient comes to your counter on a Friday evening. They are out of their oxycodone and have no refills remaining. The patient is anxious, insistent, and tells you, “I just saw the doctor this morning, and he said he would send in a new prescription. He said it was okay for me to get it.” You check your system, and there is no new electronic prescription. There is no voicemail from the doctor. The patient insists, “But he told me I could get it! I need it now!”
Deconstructing the Conflict:
- The Patient’s Need (The Nurse’s Request): The patient has a legitimate need for their medication. Their desire is real and immediate.
- The Bypassed Procedure (The Override): The patient is asking you to bypass the fundamental, legally required procedure: you must have a valid, new prescription in hand before you can dispense a Schedule II medication. Their verbal claim that “the doctor said it was okay” is the equivalent of a nurse asking for an override based on a verbal conversation.
- Your Role as Gatekeeper (The Pharmacist’s Duty): You know you cannot dispense the medication. It would be a violation of the law and a massive patient safety risk. What if the doctor changed the dose? What if they decided to stop the medication entirely? You are the final checkpoint.
Your “Yes, and…” Playbook in Action:
You don’t just say “No” and stare at the patient. You use the exact same collaborative problem-solving technique:
“Yes, I absolutely want to help you get the pain medication you need, and for me to be able to legally and safely dispense it, I need to have the actual prescription from your doctor. Let me call his after-hours service right now and see if we can get him to send it electronically or call in a verbal prescription to get you through the weekend.”
You have validated the patient’s need while firmly upholding the safety standard. You have taken ownership of solving the problem. This is the exact same skill set, mindset, and “etiquette” required to manage ADC overrides in the hospital. You are already an expert at this.
