Printing the Wrong ECG for a Patient

Computerized electrocardiographs can print ECGs that have been previously acquired. Consequently, if ECGs are consecutively acquired without any patient information, the probability of inadvertently printing a previously acquired ECG and using it as if it is the patient’s current ECG is increased. To avoid the problem, acquire ECGs using the steps outlined in this document. Always check the date/time stamped on the report to see if it matches the date/time when you acquired the ECG.

Pay Attention to Acquisition Date and Time Every printed report contains the date and time when the ECG was acquired. This is for several reasons: l

If there is no patient identification information on the report, it serves as the only unique identifier for that report.

l

If multiple ECGs are acquired for a patient, the date/time is used to sort the set of serial ECGs so a physician can make sense of the ECG changes necessary for identifying specific conditions.[1]

l

To properly assess a patient and interpret their ECG, it is important to know when the ECG was taken in relation to the patient’s symptoms and/or treatment. [1, 2, 3]

l

Acquiring a timely ECG has been found to be the most important factor in reducing time-to-treatment for emergency cardiac catheterization lab procedures.[4, 5, 6, 7] Therefore, the date and time of an ECG is a required metric for European data registries used to evaluate and improve time-to-treatment.[8, 9, 10, 11]

As a result, GE Healthcare prints the acquisition date/time on every report and this practice has been adopted as a safety and performance requirement for computerized electrocardiographs in Europe.[12]

How To Check Date And Time Of ECG Acquisition Before delivering an ECG report that you acquired, always confirm that the date and time stamped on the report matches the current date and time displayed on the electrocardiograph. See the following example:

Steps for Acquiring an ECG There are many educational materials available that describe proper skin preparation, lead placement, and so on, to obtain a quality ECG recording. Instead of reiterating these, this document focuses on the interaction between the user and the computerized electrocardiograph to eliminate the possibility that a previously acquired ECG could be mistakenly printed and used as if it is the patient’s current ECG.

1.

Turn The Device On And Connect The Patient The following diagram represents the layout of the screen when the device is turned on. As each lead-wire is attached to the patient, the ECG signal for that lead is updated on the display in real-time. The overall purpose of this display is to help the user determine whether the quality of the ECG signal is adequate for obtaining a 12-lead ECG record that can be printed, transmitted and/or stored. The user can select specific ECG leads for closer inspection while applying different gain or filter settings. Since it takes some time for the skin/electrode interface to

settle before a quality ECG can be obtained, it is customary during this phase of the test to enter patient information.

6

The bottom of the screen has labels that indicate the current function of the soft keys located directly underneath the display. Some devices have fewer soft keys or dedicated hard keys for these functions.1

2.

Enter Patient Identification When possible, enter patient identification information. Regulatory bodies have already identified that a leading cause of medical errors is the lack of patient identification information on clinical reports. Since computerized electrocardiographs can store and print previously acquired ECGs, there is a possibility that a printed report can be associated with the wrong patient. Sometimes, there are situations when patient information cannot be entered, such as during an emergency. However, if ECGs are routinely acquired without any patient information, the probability of inadvertently printing a previously acquired ECG and mistakenly using it as if it is the patient’s current ECG is increased. It is possible to configure some GE Healthcare electrocardiographs to require some form of patient identification to be entered before an ECG is acquired. However, if a user does not want to ever enter any patient information, then the aforementioned configuration will be rendered useless and turned off. Options to consider: Bar code scanner or other automated approach If your clinical environment uses bar codes, some GE Healthcare electrocardiographs can be optionally configured with a bar code scanner. This makes it very easy to enter accurate patient demographics from the patient’s wrist band or a printed label. In a matter of seconds, an ECG record can be uniquely identified and associated with the correct patient information without any typographical errors. GE Healthcare devices can also support card readers or other sophisticated solutions, such as automatically interfacing with systems that provide patient information.

1.

The MAC 1200 has no soft keys. All functions are supported via hard keys. For example, patient information is selected via a dedicated hard key. MAC 600, MAC 800 have 4 soft keys. MAC 1600, MAC 2000, MAC 3500, MAC 5000, MAC 5500, and MAC 5500 HD have 6 soft keys as shown in step 1.

Press The Hard Key To Acquire An ECG To acquire a 12-lead ECG record, press the hard key of the electrocardiograph dedicated for this purpose.2 On some device models, the patient cable also has a hard key for acquiring an ECG.

If you press the hard key again, another ECG will be acquired with a later time stamp of acquisition.

On the MAC 1200, the hard key is green and labeled “start”. For the other MAC carts, they hard key is labeled “ECG”.

4.

Print / Copy Keys Now Enabled At this point, the screen menu will display as follows.3

This is the only point in the workflow when the print/copy keys are active. The purpose of the print/copy keys is to allow you to inspect the ECG report on the display before printing it or, if necessary, generate extra copies. During this step, if you press the hard key to record an ECG, it will acquire another ECG using the same demographics. But even more importantly, this freshly acquired ECG will replace the prior one that was waiting to be printed with the print/copy keys.

5.

Select Any Other Soft Key - Print/Copy Keys Become Disabled If “Same Pat” or “Next Pat” is selected, the device will return to step 1 with the patient demographics appropriately retained or cleared.4

6.

When You Are Finished Turn the device off.5 Or, if it is preferable to leave the device on, put it back to the “Main Menu” or select “Next Pat”. Do not leave the device in a state where it is in the process of acquiring

3. 4. 5.

Some devices can be configured to have a print preview screen. In this case, the screen is no longer showing real-time waveforms. Instead, the report that has just been acquired is displayed. If you want to accept that report, you select “continue” and then the next screen that is displayed shown in step 4. On the MAC 1200, if the hard key “Pat Info” is pressed, the hard “Copy” key will be disabled. Some devices can be configured to automatically turn off.

an ECG report for a patient. Remember, the next person may have less training than you do. So please leave the device in a state that is ready to start a new test.

What You Should Do: Any of the following actions will prevent the occurrence of printing the wrong ECG for a patient:

l

Pushing the ECG button to record an ECG, or

l

Pushing “Next Patient”, “Same Patient”, or “Main Menu” after ECG test is complete, or

l

Turning the device off between use, or

l

Entering patient information for each patient.

l

Always check the date / time of acquisition to see if it matches the time that you acquired the ECG.
