Summary
The Medical Priority Dispatch System (MPDS) often over-triages patients with abdominal pain, leading to unnecessary advanced life support (ALS) use. Improved MPDS protocols are needed for accurate patient classification.
Area of Science:
- Emergency Medical Services
- Prehospital Care
- Medical Protocols
Background:
- Medical Priority Dispatch System (MPDS) protocols guide emergency medical services (EMS) response levels.
- Determining the appropriate level of EMS response for abdominal pain is crucial.
Purpose of the Study:
- To assess the proportion of abdominal pain patients who truly benefit from advanced life support (ALS) as determined by MPDS protocols.
Main Methods:
- Reviewed 9-1-1 calls processed by MPDS for abdominal pain patients receiving ALS.
- Excluded cases with non-protocol dispatch or transport to non-study hospitals.
- Analyzed EMS run sheets and hospital records for ALS intervention necessity, ED disposition, hospital course, and final diagnosis.
Main Results:
- Of 218 analyzed patients, only 12 (6%) had potentially life-threatening conditions requiring ALS.
- Seventeen patients (9%) potentially benefited from ALS, though not life-threatening.
- The majority, 157 patients (84%), did not require ALS intervention.
Conclusions:
- Current age- and gender-specific MPDS protocols lead to significant overtriage and overuse of ALS for abdominal pain patients.
- Development of more accurate MPDS questions beyond demographics is recommended for better patient classification.
