Australian Health Systems Reduce D2B and D2N Times by 28 and 33 Minutes Respectively [Preliminary Research]

By Hannah Ostrem

To determine if Pulsara can improve management timelines for patients suspected of having a stroke or cardiac event, researchers  in Australia have conducted a pilot study with a 6 month pre-post historical control design. 

The researchers give the following background to the study:

  • "Rapid treatment of patients with suspected acute stroke or cardiac events involves pre-hospital (paramedics) and hospital clinicians from multiple departments including: emergency, medical, neurology or cardiology, radiology or catheterisation."
  • "Clinicians repeat patient details using multiple communication methods (phone, fax, pager, face-to-face) and record details in various systems."
  • "Inefficient communication may contribute to treatment delays for these time-critical conditions."

In suspected stroke patients, the cohorts were similar (pre/post: n=107/176 patients; median age 80/77 years; 49%/48% male), but in suspected cardiac patients, the cohort was older, and more female (pre/post: n=11/24 patients; median 71/60 years; 67%/79% male).

Key care time metrics including hospital arrival, assessment, and treatment were recorded from Ambulance Victoria and the hospital systems in the Victoria area. 

Authors found that for STEMI patients, door to triage time was 2 minutes faster with Pulsara, and the same metric was 3 minutes faster for stroke patients, p<.002 STEMI: pre n=11, 5 mins (2,7), post n=14, 3 mins (2,4) Stroke: pre n=28, 7 mins (4,14), post n=42, 4 mins (2,7)

The teams also found that door time to off-stretcher times were 5 minutes faster in STEMI patients and 8 minutes faster for stroke patients when Pulsara was used, p<.01 STEMI: pre n=11, 12 mins (7,35), post n=14, 7 mins (4,12) Stroke: pre n=28, 20 mins (13,31), post n=42, 12 mins (4,14)

In addition, EMS crews reported that hospital arrival to departure was 10 minutes faster with use of the app,  p=.006

Hospital teams also found that for stroke, door-to-CT was completed 23 minutes faster,  p=.00 pre n=48, 46 mins (28,76), post n=33, 23 mins (16,40). Stroke door-to-needle times were also 33 minutes faster, p=.02 pre n=5, 111 mins (84,113), post: n=9, 78 mins (61,91); more patients <60 minutes: pre 0/5 (0%), post 2/8 (25%)

For STEMI, door-to-balloon times were faster by 28 minutes compared to hospitals with pre-notification n=717, 55 mins (40,76), Pulsara n=5, 27 mins (26,31).

The Australian hospital and pre-hospital facilities are the first International sites to implement Pulsara, and the preliminary results of their study indicate reductions in key time metrics for treatment of patients with stroke or acute cardiac events. Two regional hospitals in Victoria and 25 Ambulance Victoria branches are currently conducting a 12-month trial.
