Medical priority system1/22/2024 ![]() ![]() This performance analysis may be used to identify target protocols for future improvements. The Medical Priority Dispatch System exhibits at least moderate sensitivity and specificity for detecting high acuity of illness or injury. Sixteen of the 32 protocols performed no better than chance alone at identifying high-acuity patients. The best-performing protocol overall was the cardiac-arrest protocol, and the protocol with the overall poorest performance was the one for unknown problems. The cardiac-arrest protocol had the highest PPV (92.6%, 95% CI = 90.3% to 94.3%), whereas the convulsions protocol had the highest NPV (85.9%, 95% CI = 84.5% to 87.2%). The most sensitive protocol for detecting high acuity of illness was the breathing-problem protocol, with a sensitivity of 100.0% (95% CI = 99.9% to 100.0%), whereas the most specific protocol was the one for psychiatric problems, with a specificity of 98.1% (95% CI = 97.5% to 98.7%). Sensitivity and specificity to detect high-acuity illness, as well as positive predictive value (PPV) and negative predictive value (NPV), were calculated for all protocols. Duplicate calls, nonemergency transfers, and canceled calls were excluded. To determine the relationship between MPDS dispatch priority and out-of-hospital CTAS.Īll emergency calls on a large urban EMS communications database for a one-year period were obtained. The Canadian Triage and Acuity Scale (CTAS) is a standard patient acuity scale widely used by Canadian emergency departments and EMS systems to prioritize patient care requirements. This information is important for Medical Directors when assessing the risk of refusing to provide ambulance service to low acuity calls.Although the Medical Priority Dispatch System (MPDS) is widely used by emergency medical services (EMS) dispatchers to determine dispatch priority, there is little evidence that it reflects patient acuity. Among them 59.22% were triaged as GREEN using the MTC (sensitivity 17.86% and specificity 92.53%).Ĥ0.78% of patients categorized as low acuity were under-triaged, while 24.23% categorized as high acuity are over-triaged based on MTC. 510 dispatches were categorized as low acuity cases. 2534 dispatches were categorized as high acuity cases, from which 75.73% were triaged as RED using the MTC (sensitivity 68.95% and specificity 63.63%). Total of 4474 dispatch data were analysed and compared to MTC criteria provided by the EMS responder. The MTC criteria provided by EMS responder is considered as gold standard to measure the reliability of AMPDS. We excluded data from interfacility transfers and maternity cases and patients triaged to Yellow Zone from analysis. Data is collected from MECC Hospital Sg Buloh between January 2015 to December 2017 for analysis. Our objectives are to measure the reliability of AMPDS to predict patients requiring prehospital resuscitative intervention compared to patients whom would not benefit from ambulance transport to hospital. This is a retrospective descriptive analysis comparing MPDS patient prioritization with that of EMS responders using the Malaysian Triage Criteria (MTC). Thus, it is important to have local data on the accuracy of dispatch patient categorization particularly to understand the over-triaging and under-triaging rates in prehospital care response. Dispatch protocols are greatly influenced by the Emergency Medical Service (EMS) System that it is applied to. In Malaysia, the Medical Emergency Coordination Centre (MECC) uses the Advanced Medical Priority Dispatch System in prioritizing ambulance response. ![]() RESULTS-: Among 3474 transported patients, 96 (2.8) had a final diagnosis of stroke or transient ischemic attack. ![]() Data are presented as median and 25-75 interquartile ranges. Results: In 225 clusters 1500 events were eligible for analysis. Dispatch centre has an important role in matching resource to patients’ needs in prehospital environment. Dispatcher-assigned Medical Priority Dispatch System codes for each of these patient transports were abstracted from the paramedic run sheets and compared to final hospital discharge diagnosis. The emergency medical service of the intervention group got, based on the dispatchers impression, a pre-alert alarm-message followed by the standard Medical Priority Dispatch System query whereas the control group did not. ![]()
