Brief Summary:
Skill with pulmonary artery catheter (PAC) waveform interpretation is inadequate among physicians and nurses. We, the investigators at Massachusetts General Hospital, have developed a web-based computer program to assist physicians and nurses in PAC waveform interpretation. We will study the effectiveness of this program on improving the interpretation of waveforms on a computer-based test.

Condition or disease Intervention/treatment Phase
Pulmonary Artery Catheter Waveform Interpretation Device: Web-based waveform interpretation guide Not Applicable

Detailed Description:
The pulmonary artery catheter (PAC) guides diagnosis and treatment in the intensive care unit (ICU), but studies have shown that physicians and nurses collectively have inadequate skill in interpreting PAC waveforms. We have developed a Web-based application that provides physicians and nurses with rapid access to relevant PAC-related content for use in patient care situations. The application begins with a visual index that assists clinicians in the recognition of both normal and abnormal waveforms and provides waveform-specific links to concise advice on making accurate pressure measurements, troubleshooting system problems, and avoiding complications of catheter use. Initial evaluation will consist of a before-and-after trial to determine whether the application improves test performance in the areas of waveform recognition, accuracy of measurement, and appropriateness of action. Once the resource is in production, we will electronically log usage and survey users to evaluate the extent and effect of actual utilization.

Top of Page Study Description Study Design Arms and Interventions Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Score on a Computer-based Test on Pulmonary Artery Catheter Waveform Interpretation [ Time Frame: 1 month ]
    The study was terminated before the primary outcome could be measured. None of the participants took the post-intervention test.


Secondary Outcome Measures :
  1. Individual and Collective Frequency of Use and Usage Patterns of the Web-based Waveform Interpretation Guide [ Time Frame: 1 year ]
    The study was terminated before the secondary outcome could be measured. Usage data was not collected over the following year.
