The Service

Our composite 180-bed community hospital sees about 52,000 emergency department visits a year, and roughly 4,300 of those patients arrive with chest pain or symptoms that could be a heart attack. Most do not have one, and the department's job is to find the few who do while sending the rest home safely and without a long wait. Two years ago the hospital adopted a high-sensitivity cardiac troponin I test and a clinical pathway that sorts patients using a troponin drawn at arrival and a second drawn two hours later. The pathway follows the direction of the national chest pain guideline, which favors high-sensitivity troponin and structured decision pathways for patients with acute chest pain (Gulati et al., 2021).

A pathway built on timed blood tests only works if the results come back on time. Emergency physicians have complained that results often arrive well after the two-hour mark, and patients who could have gone home wait in hallway beds. The quality director asked administration to define what quality means for this service and to specify a measure the laboratory and emergency department can share.

Dimensions of Quality for This Service

The report that launched the modern quality movement set out six aims (Institute of Medicine, 2001). In its terms, care should be safe, effective and timely, and also efficient, equitable and built around the patient. Each applies to chest pain testing in a specific way. Safety means that no patient with a heart attack is sent home and that no specimen is mislabeled. Effectiveness means the pathway is followed as designed, including the second troponin. Patient-centered care means patients understand why they are waiting and what the results mean. Timeliness means results are available when the pathway calls for them. Efficiency means beds, staff and repeat blood draws are not wasted. Equity means the process works the same way for every patient, whatever their language, insurance or time of arrival.

Timeliness is the dimension that fails most visibly here, and it also drives the others. A late second result keeps an emergency bed occupied, which affects efficiency; it lengthens the wait, which affects patient experience; and when physicians work around delays by deciding without the second troponin, it affects safety and effectiveness. In this service, a slow result is not only an inconvenience; it is how the other five aims begin to fail.

Structure, Process and Outcome

Donabedian (1988) offered three lenses for judging care: structure, meaning the facilities, staff and equipment available; process, meaning what clinicians and staff actually do; and outcome, meaning the changes in patients' health that follow. He reasoned that the three are connected in sequence, each raising the likelihood of the next. Applied to troponin testing, structure includes the pneumatic tube system, the analyzer and its staffing, and the laboratory information system. Process includes the time from the physician's order to the blood draw, from the draw to the laboratory, and from the laboratory's receipt of the specimen to the posted result. Outcomes include length of stay for patients discharged from the pathway and, most importantly, missed heart attacks.

Outcome measures such as missed myocardial infarction are rare events at this hospital's volume and cannot guide monthly improvement. A process measure of turnaround is frequent, directly controllable and, through the pathway, closely tied to the outcomes that matter. It will therefore be the primary measure, with outcome and balancing measures alongside it.

The Primary Measure

A measure is useful only if two people calculating it would get the same number, so it must be specified precisely. The primary measure is the percentage of emergency department high-sensitivity troponin results reported within 60 minutes of the order. The numerator is the number of troponin results with a verified result time no more than 60 minutes after the order time. The denominator is all high-sensitivity troponin tests ordered in the emergency department during the month, for both the first and second draws. Excluded are tests canceled before collection, tests on patients who left before the draw, and tests where the physician ordered a timed draw for later. All three timestamps come from the laboratory information system, so no manual collection is needed.

Order-to-result was chosen rather than the laboratory's usual receipt-to-result interval because the pathway depends on the whole interval. The laboratory's own measure has looked good for years, averaging 24 minutes, while the physicians' experience has been poor; the gap lies before the specimen reaches the laboratory, and a measure that starts at receipt cannot see it. Last quarter, 58% of results met the 60-minute standard, with a median of 64 minutes. The initial target is 90% within 60 minutes. The emergency and laboratory directors set that figure together after looking at what the pathway needs: if the first result posts within an hour and the second draw happens on time, a low-risk patient can be discharged roughly three hours after arrival. A target set only by the laboratory would likely have been lower, and one set only by the physicians higher; agreeing on it jointly means neither department can later treat the number as the other's problem. The target will be reviewed once the process has been redesigned and its new capability is known.

Outcome and Balancing Measures

Two further measures will be reported with the primary one. The outcome measure is the median emergency department length of stay for patients discharged home from the chest pain pathway, currently 5.1 hours, which should fall if results arrive sooner. The balancing measure watches for harm from the improvement effort itself: the rate of hemolyzed troponin specimens that must be redrawn. If nurses rush blood draws or send specimens through the tube system before they are properly handled, hemolysis could rise, forcing redraws that delay results and add needle sticks. It is currently 2.8% of troponin specimens.

The measures will also be stratified by shift and by whether the patient was in a hallway bed, since preliminary review suggests delays cluster at night and in hallway spaces. Stratifying the data this way keeps the equity aim in view, making sure an average does not hide a group of patients who are consistently served worse.

Reporting and Ownership

The measures will be reported monthly on a single page shared by the emergency department and laboratory, with the primary measure displayed over time rather than as a single monthly percentage, so that a genuine change stands apart from ordinary month-to-month noise. The emergency department nurse manager and the laboratory supervisor will jointly own the primary measure, since neither controls the whole interval alone. Results will go to the hospital's quality committee each quarter. The next steps in this course, mapping the process and analyzing the data, will build on this definition, so it has been written to remain stable: if the definition changed midway, every later comparison would lose its meaning.
