Table 4 Performance outcomes of EPs’ use of LIE systems
From: Improving performance in the ED through laboratory information exchange systems
Performance outcomes of LIE usea | Mean | SD |
|---|---|---|
Outcomes of iEHR use (n = 120 users) | ||
Accessing the laboratory test results provided by the iEHR: | ||
- Improves the continuity of my patients’ care; | 4.3 | 0.6 |
- Allows me to make better clinical decisions; | 4.1 | 0.6 |
- Provides me with results that I cannot obtain from my usual information sources (e.g., the EDIS); | 4.0 | 0.8 |
- Improves the way in which I evaluate patients; | 3.9 | 0.8 |
- Reduces duplication of the lab tests that are prescribed to my patients; | 3.8 | 1.0 |
- Prevents me from missing an important result; | 3.7 | 0.8 |
- Allows me to intervene more rapidly and effectively with my patients; | 3.7 | 0.9 |
- Increases the safety of my patients’ care; | 3.7 | 0.9 |
- Provides me with an overall view of my patients’ lab results (patients’ test history); | 3.6 | 1.0 |
- Allows me to discharge patients more rapidly; | 3.2 | 0.9 |
- Provides support to my clinical research or my performance measurement activities. | 1.3 | 0.7 |
Overall performance outcome of iEHR use for LIE purposesb | 3.6 | 0.5 |
Outcomes of EDIS use (n = 18 users) | ||
- I can take faster action when laboratory test results are available in the EDIS. | 4.1 | 0.9 |
- The information being in one place, I gain time when I follow up on lab results through the EDIS. | 3.8 | 1.3 |
- The ability to generate tables and graphs with the EDIS is very helpful in interpreting lab results. | 3.6 | 1.3 |
Overall performance outcome of EDIS use for LIE purposesd | 3.8 | 0.9 |
Outcomes of LRV use (n = 150 users) | ||
- The viewer provides most of the lab test results that I need to care for patients arriving in the ED. | 4.4 | 0.8 |
- My patients’ lab test results are easier to consult in the viewer than in the paper medical record. | 4.2 | 1.0 |
- It is quicker for me to access the viewer to consult patients’ previous lab test results than waiting to receive their paper medical record. | 4.2 | 1.2 |
- As most of my patients reside in the region, I have little use for the iEHR because the viewer provides me with most of the lab test results that I need. | 2.9 | 1.5 |
- The viewer is very useful in allowing me to access test results produced by the public laboratories in my region. | 2.2 | 1.5 |
Overall performance outcome of LRV use for LIE purposesc | 3.6 | 0.8 |
