Quality Improvement Project Door to Balloon Times for Cardiac Patients

Door Balloon

Door-to-Balloon Time

The quality indicator examined herein is the measurement known as door-to-balloon time, which is a defined element in emergency cardiac care that refers to the time from patient entrance to an emergency department to the time a catheter wire passes the lesion responsible for a myocardial infarction. An increase in door-to-balloon time carries with it an increased risk for tissue damage and thus more permanent complications and detriments to patients' health, and thus certain standards have been set in an effort to promote best practices and measure the efficacy of emergency department treatment of myocardial infarctions. The current recommendation for door-to-balloon time is ninety minutes or less, and this is a number that should be strived for with every patient, not simply as an average for the emergency treatment of myocardial infarctions in a given department as a whole, as again increased time can means significant detriment to long-term health outcomes for each individual patient. Using door-to-balloon time as a measure of care efficacy and quality provides a direct and quantifiable method that can be easily tracked over time and in response to various improvement efforts and changes to policy or practice.

According to the six observations included in this chart, the emergency department in question appears to be providing excellent care as measured by door-to-balloon time, with the longest time measured (sixty-four minutes) still substantially lower than the current recommended maximum time of ninety minutes -- only two thirds of this time, in fact. The shortest tome observed for door-to-balloon achievement, twenty-five minutes, is especially impressive and was likely of tremendous benefit to the patient in that particular case. Both extremes were also relatively equidistant from the mean door-to-balloon times of the observations included in the chart, which is just under forty-nine minutes; this suggests that this mean is a decent estimate for overall door-to-balloon time in the observed emergency department. This mean is slightly closer to the high end of the observations, however, as the twenty-five-minute low end is in fact substantially lower than the other times observed, though it is also not far from the median door-to-balloon time of fifty-three minutes. All of these numbers, when compared to the current recommendation of ninety minutes for door-to-balloon time, suggest that the department is operating at a substantial level of efficiency, efficacy, and quality of care, though of course door-to-balloon time cannot be used as the sole measure in determining departmental performance and efficacy. The small sample size represented by the information in the chart is also a weak point of this data and the conclusions that can be drawn from it, as six patients can hardly be considered a representative sample of a typical emergency department's myocardial infarction cases, however these numbers are still an indicator that the department in question is able to effectively handle the myocardial infarction cases it sees.
