One of the most common and least glamorous processes in emergency departments is collecting urine specimens for testing. With abdominal pain appearing consistently as one of the top five chief complaints in almost every ED, accounting for 12 percent to 20 percent of all patients (National Ambulatory Medical Care Survey. Adv Data 2002;328:1), and the urinalysis considered a routine part of an abdominal pain evaluation, the sheer number of specimens collected is daunting.
The vast majority of emergency departments, however, lack a clearly articulated process for collecting urine samples. The average turnaround time for a urine sample in the emergency department from the time the physician orders it until the results are returned is 89 minutes, one of the longest routine lab turnarounds in the ED. (VHA Online Data Survey, presented at VHA Regional Summit, Tucson, AZ, Nov. 5, 2006.)
Can the reliability and the efficiency of urine collections in the ED be improved? Can a model be developed and a protocol devised to standardize this process? Can reliability tools be used to do this? I have discussed reliability tools before, but in short, these strategies help guarantee certain actions to improve the reliability of service processes or clinical processes. (Improving the Reliability of Healthcare. Innovation Series 2004. [White paper.] Institute for Healthcare Improvement, www.ihi.org; accessed December 2006.) Can these tools be applied to collecting urine in the ED to improve the process?
A QI project for urine collection is outlined in the table. As with any well designed QI project, the stakeholders must start with an AIM statement, which should be focused and specific. It should spell out the project's goal, the parameters to be measured, and its time frame.
The choice of parameters to be measured is an important part of an ED QI project. Available IT support and how data will be collected must be considered. Baseline data using this measure must be obtained before the project is started. Generally data for QI in the ED can be viewed as two types: counted and measured. For urine collection, the number of occurrences can be counted (number of urine specimens, number of people waiting in triage), and the time intervals can be measured (time to urine collection, time to discharge). A QI project starts with a measure and the methodology to acquire the data. The measure is used before and after the intervention.
Forming a Team
The next step involves forming a multidisciplinary team. (The Team Handbook [3rd ed.] Madison, WI. Oriel, Inc., 2003.) Team meetings should be brief, infrequent, highly focused, and productive. The team can help promote the change package (a series of changes to be implemented as part of the QI project) among their constituent stakeholders. Often the project may involve a process change or protocol that has already been tried elsewhere, and the team meets to sign off on the elements of the project and to make minor local adjustments to the protocol.
Before launching, QI project educational sessions for staff are encouraged. It is important that all workers affected by the change understand the project and its expected outcomes to gain as much staff support as possible. Hopefully this advance promotional effort will generate enthusiasm for the project. In-service conferences, emails, bulletin boards, posters, and even threaded email conversations might be used to set the stage for a QI project.
As soon as the QI project is launched, data should be collected and a feedback loop for staff created. If there is improvement, this often can drive the improvement project by energizing the team. Often stakeholders are motivated by data. If there is no improvement early on, the team can try to assess the reasons. In most instances, gains will be seen and produce further improvement. The feedback loop is one of the most powerful tools in the reliability toolbox. Another powerful tool is the default order set. In this project, the patient with abdominal pain has a default order for a urine sample to be collected, and is walked to the bathroom for immediate collection. A physician may cancel this order, but efficiency and reliability are possible when orders are standardized and automatic.
Another tactic for achieving high reliability in health care processes involves recognizing and anticipating failures, and designing processes to mitigate them. In this model, biology will work against a 100 percent reliable urine collection. Some patients will be unable to void on command, some will have gone just before they left home, and some may be dehydrated. What to do with these patients who fail to produce a urine specimen using the new process? One fail-safe urine protocol includes:
* All patients with clinical indications are walked to the restroom prior to room placement and instructed in how to provide a urine sample. Once the sample is collected, they will be placed in a room.
* All debilitated or nonambulatory patients with clinical indications will have a catheterized urine specimen obtained upon room placement.
* All ambulatory patients unable to void will be given a timer set at 30 minutes. If the patient still has not voided, the physician will be alerted and asked to give one of the following orders:
* Start PO fluids and notify the physician if no sample is obtained in 30 minutes.
* Start IV fluids 1 liter normal saline wide and notify the physician if no sample is obtained in 30 minutes.
* Catheterize patient for urine sample.
Many ED processes are highly unreliable and consequently inefficient. By standardizing the process, we can anticipate increased reliability and efficiency. Urine collection is such a common problem, it may be the perfect place to begin applying reliability tools and to launch an ED QI project. This project and its methodology can serve as a prototype for other improvement projects.
Meanwhile, as the initiative is being launched, we might consider T-shirts and bumper stickers! Maybe we could use this slogan: “Urine Nation: It's All About Flow!”
Urine Collection QI Project
AIM Statement: To improve throughput time for patients with abdominal pain by 50% by improving the collection process of urine specimens.
* Throughput time for patients with abdominal pain.
* Arrival time to discharge/admit time.
* Turnaround time for urinalysis.
* Arrival time to results received on urine sample.
* Data may be obtained electronically through IT, with retrospective chart auditing, or real-time data gathering using a simple clipboard.
* Form a multidisciplinary team to develop and approve the change package. Meetings are brief, few in number, and focused. The team will buy in on the process changes, prompts and reminders, triggers, standardized order sets, and cueing.
* The urine collection process will be standardized.
* All patients with abdominal pain who are ambulatory will be walked to the bathroom, and the urine will be collected before the patient is placed in a room.
* This process will occur by default and without requiring a physician order.
* Place prompts and reminders of new process in triage.
* Use email, posters, flyers, and staff meetings to inform staff of the initiative.
Week 1: Sample patients with abdominal pain, and compute average overall throughput times or turnaround time (or both) on urine specimens. Educate staff about coming change.
Week 2: Implement change and measure results.
