5.4 Patient Handover, Identity Verification & Technical Device Demonstrations

Patient Handover, Identity Verification & Technical Device Demonstrations

Exam Tip: Patient handover represents the final safety checkpoint before a medication enters the patient's possession. On the PEBC exam, questions evaluate two distinct dimensions of this encounter: first, executing non-leading patient identification and correctly triaging clinical vs. technical questions; second, mastering the exact operational mechanics of administering inhalers, spacers, insulin pens, glucometers, and eye drops.

Positive Patient Identification at Handover

The handover interaction at a community pharmacy pickup counter, ambulatory clinic, or hospital discharge lounge is a critical juncture where misidentification errors can negate all preceding technical checks.

The Two-Identifier Verification Protocol

Under Canadian patient safety standards, the pharmacy professional must confirm at least two independent, unique patient identifiers before releasing any medication:

1. Full Legal Name: The patient must state their full surname and given name. Never use passive confirmation by asking, "Are you John Smith?" Rushed, distracted, or hearing-impaired patients frequently nod in agreement, resulting in medication handed to the wrong individual.
2. Secondary Unique Identifier:
   • Date of Birth (Day, Month, and Year).
   • Residential Street Address (especially valuable for confirming family members with identical names).
   • Provincial Health Card Number (PHN / OHIP / RAMQ / MSP).
   • Official government-issued photo ID (some provincial monitoring programs require identification when a monitored drug, such as an opioid, is released).

Scope Demarcation at Handover: Technician vs. Pharmacist

Provincial pharmacy regulatory authorities establish clear statutory guidelines governing professional communication during medication release:

└──────────────────────────────────────┴──────────────────────────────────────┘

Mandatory Pharmacist Handover Triggers

When releasing a prescription, the technician must immediately transfer the patient to the pharmacist if:

• The prescription is a new therapy or an altered dosage/strength for that patient.
• The provincial pharmacy regulation legally mandates direct pharmacist counseling (e.g., Schedule II behind-the-counter sales, therapeutic substitutions).
• The patient asks a clinical or judgment-based question, such as:
  • "Is it safe to take this with my blood pressure pills?"
  • "I felt nauseated after yesterday's dose—should I stop taking it?"
  • "I missed my dose this morning; should I take two pills now?"
  • "Why did the doctor switch me from atorvastatin to rosuvastatin?"

Autonomous Technician Demonstration Scope

Pharmacy technicians are fully authorized under NAPRA competencies to provide technical education and physical demonstrations on medical devices, diagnostic aids, and administration equipment. The technician educates the patient on the physical mechanics of the device, maintenance, cleaning, assembly, and practical handling.

Step-by-Step Technical Device Demonstrations

1. Pressurized Metered-Dose Inhalers (pMDIs) with Spacers

┌──────────────────────────────────────────────────────────────────────────┐
│                 pMDI with Valved Holding Chamber (Spacer)                │
├──────────────────────────────────────────────────────────────────────────┤
│ 1. Remove caps from both inhaler and spacer mouthpiece.                  │
│ 2. Inspect for foreign objects or lint inside the spacer chamber.        │
│ 3. Shake the inhaler vigorously for 5 seconds (suspension).              │
│ 4. Insert the pMDI upright into the rubber universal adapter.            │
│ 5. Sit or stand up straight; exhale fully away from the device.          │
│ 6. Place spacer mouthpiece between teeth and form a tight seal with lips.│
│ 7. Depress canister ONCE to release a single puff into the chamber.      │
│ 8. Inhale SLOWLY and DEEPLY over 3 to 5 seconds (no whistling sound).    │
│ 9. Hold breath for 10 seconds (or as long as comfortable).               │
│ 10. Wait 30 to 60 seconds before administering a second puff.            │
│ 11. Rinse mouth with water and spit out if using an inhaled steroid.     │
└──────────────────────────────────────────────────────────────────────────┘

• Slow Inhalation Rate: If the spacer whistles, the patient is inhaling too quickly. High velocity causes inertial impaction of drug droplets in the upper pharynx rather than bronchial deposition.
• Spacers Reduce Electrostatic Charge: Plastic spacers should be washed weekly in warm water with mild dish detergent and air-dried on a rack without towel-drying. Wiping with a cloth or paper towel creates an electrostatic charge on the chamber walls that attracts aerosolized drug particles, drastically reducing delivered drug mass.
• Mouth Rinsing: Inhaled corticosteroids (ICS, e.g., fluticasone, budesonide) require patients to vigorously rinse their mouth with water and spit it out after inhalation to prevent oropharyngeal candidiasis (thrush) and dysphonia (hoarseness).

2. Dry Powder Inhalers (DPIs: Diskus, Turbuhaler, HandiHaler)

Unlike pMDIs, Dry Powder Inhalers are breath-actuated; they require no chemical propellants (CFC/HFA) and depend entirely on the patient's inspiratory effort to de-aggregate and aerosolize fine powder micro-particles.

• Core Demonstration Technique:
  • Diskus: Hold level horizontally; slide lever until an audible click is heard (advancing dose counter and puncturing blister).
  • Turbuhaler: Hold upright; twist colored grip fully to the right, then twist back to the left until it clicks.
  • HandiHaler: Insert capsule into central chamber; press piercing button once and release.
  • Inhalation Technique: The patient must exhale completely away from the inhaler (never exhale into a DPI, as humid breath clumps the dry micronized powder). Place lips around mouthpiece and inhale RAPIDLY, FORCIBLY, and DEEPLY from the very start of the breath.
  • Hold breath for 10 seconds, then breathe out gently.
  • Cleaning: Never wash a DPI with water. Wipe the exterior mouthpiece with a dry tissue.

3. Subcutaneous Insulin Pens & Pen Needles

Insulin pens provide precise dosing for diabetes management, but improper injection technique leads to severe glycemic variability and lipohypertrophy.

┌──────────────────────────────────────────────────────────────────────────┐
│                     Insulin Pen Injection Technique                      │
├──────────────────────────────────────────────────────────────────────────┤
│ 1. Inspect insulin: NPH should be uniformly cloudy (roll gently 10x);   │
│    rapid/long-acting analogues (glargine, lispro) must be clear.         │
│ 2. Wipe rubber septum with alcohol swab; allow to air-dry.               │
│ 3. Attach a new safety pen needle straight onto the pen; screw tight.    │
│ 4. Prime the needle (Air Shot / Safety Test): Dial 2 units, hold pen     │
│    upright, press injection button fully until a droplet appears at tip. │
│ 5. Dial the prescribed dose.                                             │
│ 6. Cleanse injection site (abdomen 2 inches from navel, thigh, arm).    │
│ 7. Insert needle straight at a 90-degree angle into skin.                │
│ 8. Push injection button down fully until the dose counter reaches zero. │
│ 9. HOLD needle embedded in the skin for 5 to 10 SECONDS before removing. │
│ 10. Withdraw needle straight out; immediately unscrew and discard into   │
│     an approved biohazard sharps container. Never store pen with needle. │
└──────────────────────────────────────────────────────────────────────────┘

• The Hold Before Withdrawal: Pen manufacturers tell patients to keep the needle in the skin for a set count (commonly about 10 seconds) after the dose counter reaches zero. Pulling out early lets part of the dose leak onto the skin, which can cause unexplained high blood sugar.
• Removing Needles After Each Use: Leaving a needle attached to an insulin pen allows room air to enter the cartridge as temperatures fluctuate, creating air bubbles that compromise subsequent dose accuracy. It also permits insulin evaporation and crystal formation that clogs the micro-bore needle.

4. Blood Glucose Monitoring Systems (Glucometers)

• Hand Hygiene: Wash hands with warm soapy water and dry them well. Warm water improves blood flow to the fingertips. Food or sugar residue on unwashed fingers can falsely raise the reading. If an alcohol swab is used, let the site dry completely, because wet alcohol stings and can distort the result.
• Lancing Mechanics: Lance the fleshy outer side of the fingertip, rather than the sensitive central finger pad. The lateral edges have fewer sensory pain nerve endings and greater capillary density.
• Sampling: Bring the test strip reaction channel to touch the blood droplet (capillary action draws blood into the chamber). Never smear blood across the top of the strip.

5. Ophthalmic Drops & Ointments

• Aseptic Technique: Wash hands thoroughly before touching ocular tissues. Never let the dropper bottle tip touch the eyeball, eyelashes, eyelids, or fingers.
• Administration Pocket: Tilt head backward, look up at the ceiling, and gently pull the lower eyelid down with a clean index finger to create a conjunctival pocket (cul-de-sac).
• Single Drop Instillation: Instill exactly one drop into the conjunctival pocket. The human eye holds approximately 25 to 30 microliters of fluid, while a standard commercial drop is 40 to 50 microliters; instilling multiple drops simultaneously simply overflows down the cheek without therapeutic benefit.
• Nasolacrimal Occlusion (Punctal Occlusion): Immediately close the eye gently (do not squeeze shut or blink repeatedly, which pumps drug into the tear duct) and press an index finger firmly against the inner corner of the eye (lacrimal sac) for 1 to 2 minutes.
  • Clinical Purpose: Blocks drainage through the nasolacrimal duct into the nasal mucosa, drastically reducing systemic drug absorption and minimizing cardiovascular or respiratory adverse effects (crucial for ophthalmic beta-blockers like timolol).
• Spacing Multiple Medications: If two different eye drop products are prescribed, wait at least 5 minutes between drops so the second drop does not wash out the first. If both drops and an ointment are prescribed, always instill drops first, wait 5 minutes, and apply the ointment last.
