Trial Outcomes & Findings for Randomized Trial of a Quality Improvement Intervention to Decrease D2B Time in Primary PCI for AMI (NCT NCT01625104)

NCT ID: NCT01625104

Last Updated: 2017-12-15

Results Overview

Arrival time in Emergency Department to first balloon inflation in the coronary artery. Any reduction in median Door to Balloon Time from baseline to follow-up was counted as reduction in time

Recruitment status

COMPLETED

Study phase

NA

Target enrollment

882 participants

Primary outcome timeframe

Arrival to balloon inflation, measured in minutes (generally less than 120 mins)

Participant Flow

6 sites were randomized to the aggressive strategy and 6 sites were randomized to control.

Site were randomized according to baseline Door to Balloon times.

Measure
Group 1: Agressive Strategy
Hospitals were randomized to an aggressive intervention strategy or to "business as usual". The hospitals randomized to the aggressive intervention strategy underwent the following: 1. Grand Rounds conducted by physician and nurse from the Coordinating Center. This included a formal presentation on the evidence supporting rapid time to treatment in STEMI patients and evidence based strategies for reducing treatment delays. 2. Discussion with staff regarding perceived barriers to treatment and suggestions/ideas for strategies to overcome these barriers 3. Follow-up monthly phone conferences to continue to discuss strategies and ideas sharing 4. Written plan from sites detailing plans to change processes of care.
Group 2: Control
Hospitals randomized to the control group were instructed to conduct "business as usual".

Group 2: Control Strategy
n=434 Participants
Hospitals randomized to the control group were instructed to conduct "business as usual". Business as usual was described as site specific protocol for treatment of STEMI patient +/- any ongoing quality improvement efforts. No specific recommendations were given to sites from the coordinating center.
