Medical Conditions & Diseases
- DM - diabetes mellitus
- T2D - type 2 diabetes
- CKD - chronic kidney disease
- ESRD - end-stage renal disease

- PCP - primary care provider/physician (only 18% of laypeople understand this) 3
- PICU - pediatric intensive care unit
- ICU - intensive care unit
- HCW - healthcare worker 10
Scoring Systems & Assessments
- SCORE2 - Systematic COronary Risk Evaluation 2
- SCORE2-OP - Systematic COronary Risk Evaluation 2–Older Persons
- DASH - Dietary Approaches to Stop Hypertension
- BMI - body mass index
- QoL - quality of life

Critical Safety Considerations
The most problematic ambiguous abbreviations include:
- Pt - patient vs. physiotherapy (most common ambiguous abbreviation) 1
- MS - multiple sclerosis vs. mental status 11
- IU - international unit (93% of trainees use this despite being on "do not use" lists) 2
- Q.D. - once daily (89.6% of trainees use this incorrectly) 2
- µg - microgram (96% misuse rate) 2
- SC - subcutaneous (90% misuse rate) 2
Research demonstrates that 31.9% of all abbreviations used in discharge summaries are ambiguous, representing 2.8% of all words written 1. Only 32% or fewer laypeople correctly understand common medical acronyms, even among educated populations 3. Board-certified physicians achieve 88.7% accuracy in deciphering abbreviations, while machine learning models reach 97.6% 11.
Avoid using abbreviations entirely when communicating with patients, as the 21st Century Cures Act (2020) grants patients direct access to their medical records, making readability essential 12.
