Prescribing challenges
Procurement in an era of drug shortages –
keeping it safe
Preparation and dispensing – includes
sterile preparation
Administration of medications – timing, unit
dose, bedside medication verification
Monitoring of therapy, Medication Use
Evaluations
Prescribing Challenges Objectives



Describe the optimal environment for
safe prescribing
List the necessary tools for enhancing
the knowledge of medications
Discuss the advantages and
disadvantages of computerized
physician order entry (CPOE)
The Problem




The Institute of Medicine Report revealed that
errors in medical care are responsible for
many deaths
Many health care providers are not aware of
their responsibilities
Medication errors responsible for numerous
adverse outcomes, including death
This results in high cost (emotional and
financial)
Who are the participants?






Physicians
Nurses
Pharmacists
Respiratory Therapists
Patients
The casual observers who can alert the
care providers about opportunities for
errors

PRESCRIBING
25.01.12, 25.01.13


Is a collaborative effort
There is an increasing body of
knowledge
– New therapeutic entities
– Drug interactions
– Allergies database
– Food-drug interactions
– Post-marketing data
PRESCRIBING

Physician (and other prescribers)
responsibilities:
– Diagnosis
– Drug and dosing choices
– Medication reconciliation

Pharmacist responsibilities (25.01.15, 25.01.16)
– Drug information
– Protocol-based management of patient
medications
– Review of physician orders
Training, Memory and Best Efforts
As Safety System Tools




1980: medical school graduates needed
to really know 60 drugs well
2000: this number was estimated at 600
drugs
2012: add another 100-200 drugs
Drug-drug interactions increase
exponentially with these numbers

Medication Prescribing Process:
Computerized Prescriber Order Entry
(CPOE)
– Computer with 3 Interacting Databases
• Drug History
• Drug Information/Guidelines Database
• Patient-Specific Information
– Avoids
•
•
•
•
Illegible Prescriptions or orders
Improper Terminology
Ambiguous Orders
Incomplete Information
Schiff GD. JAMA 1998; 279: 1024-9.
Computerized Physician Order
Entry (CPOE)


Provides Decision Support
Warns of Drug Interactions
– Drug-Drug
– Drug-Allergy
– Drug-Food





Checks Dosing
Reduces Transcription Error
Reduces number of lost orders
Reduces duplicative diagnostic testing
Recommends cost effective, therapeutic
alternatives
CPOE Advantages
Automate ordering process
 Reduces Order Errors

– Standardized, legible complete orders
– Alerts

Data collected on variances in practice
Improved Quality


CPOE allows for physician reminders of
best practice or evidence-based
guidelines
Indiana University study
– Pneumococcal vaccine in eligible patients
0.8%
36.0%
– Heparin prophylaxis
18.9%
32%
CPOE Disadvantages




Errors still possible
Alerts
Multiple steps
Access
Dosage Calculations


Recognized cause of medication errors
Use patient-specific information
– height
– weight
– age
– body system function
Cohen MR. Medication Errors. Causes, Prevention, and Risk Management; 8.1-8.23.
Dosage Calculations:
Error Prevention


Avoid calculations
Cross-checking
Cohen MR. Medication Errors. Causes, Prevention, and Risk Management; 8.1-8.23.
ISMP Medication Safety Alert 1996; 1 (15).
Verbal Orders:
Error Prevention



Avoid when possible
Enunciate slowly and distinctly
State numbers like pilots
(i.e., “one-five mg” for 15 mg)


Spell out difficult drug names
Specify concentrations
Cohen MR. Medication Errors. Causes, Prevention, and Risk Management; 8.1-8.23.
Conflict Resolution





Communication is essential
No one is right all the time
Take the time to listen
Beware of instilling an atmosphere of
fear
Interdisciplinary collaboration
Cohen MR. Medication Errors. Causes, Prevention, and Risk Management; 8.1-8.23.
Patient Education



Educate patients about their medications
Purpose of each medication
Name of drug, dose, how to take, etc.

Provide patients with understandable written
instructions

Lack of involving patients in check systems
Inform patients about potential for error with
drugs known to be problematic


serious medication errors.
Major advances have been made in
improving prescribing safety
Technology is our friend
Interdisciplinary interactions go a long
way toward preventing errors
