Safe Medical Abbreviations for Clinical Documentation
Medical abbreviations should be avoided in clinical documentation whenever possible, as they pose significant risks to patient safety and effective communication between healthcare providers.
Why Abbreviations Are Problematic
The evidence strongly indicates that abbreviations in medical documentation lead to misunderstandings and potential clinical errors 1. Studies show that even specialists can correctly interpret only about 57% of abbreviations within their own field, with significantly lower rates among other healthcare professionals 1.
Risks of Abbreviation Use:
- Misinterpretation across different specialties
- Compromised patient safety
- Increased workload due to clarification needs
- Worse patient outcomes 2
Standard Approved Abbreviations
While abbreviations should generally be avoided, several medical guidelines do include standardized abbreviation lists for specific contexts:
Common Standardized Medical Abbreviations:
- ADL: Activities of Daily Living 3
- IADL: Instrumental Activities of Daily Living 3
- IV: Intravenous 3
- PO: By mouth (per os) 3
- BID: Twice daily 3
- ICF: International Classification of Functioning, Disability, and Health 3
Specialty-Specific Abbreviations:
- UDS: Urodynamics 3
- RBUS: Renal and Bladder Ultrasound 3
- CIC: Clean Intermittent Catheterization 3
- LVP: Large-Volume Paracentesis 3
- SBP: Spontaneous Bacterial Peritonitis 3
- AKI: Acute Kidney Injury 3
Abbreviations to Avoid
Several abbreviations have been specifically identified as dangerous and should never be used:
"Do Not Use" Abbreviations:
- Q.D. (once daily) - Write out "once daily" instead 4
- IU (international unit) - Write out "international unit" 4
- µg (microgram) - Write out "microgram" 4
- SC (subcutaneous) - Write out "subcutaneous" 4
- ZnSO4 and MgSO4 - Write out full chemical names 4
Best Practices for Documentation
- Write out terms in full on first mention, followed by the abbreviation in parentheses if it will be used repeatedly
- Use only widely recognized abbreviations from official guidelines
- Avoid specialty-specific abbreviations when communicating with providers from other disciplines
- Consider your audience - documentation read by multiple specialties should contain fewer abbreviations
- Include a legend for any necessary abbreviations in complex documentation
Implementation Strategy
For healthcare organizations seeking to improve documentation safety:
- Create an approved abbreviation list specific to your institution
- Conduct regular training on safe documentation practices
- Implement electronic health record tools that flag dangerous abbreviations
- Perform periodic audits of documentation for abbreviation compliance
- Establish a culture where clarifying unclear abbreviations is encouraged
Research shows that even with training, healthcare providers frequently use unapproved abbreviations, with studies finding that over 90% of providers used at least one "do not use" abbreviation 4. This highlights the need for ongoing education and system-level interventions to improve documentation safety.
