Purpose of the project:
The impact of human error on patient safety is a topic that has received considerable attention in recent years. Despite this heightened awareness and interest, the factors that actually contribute to medical errors remain poorly understood. The purpose of the present project, therefore, is to study factors that affect surgical and teamwork performance in the operative environment.
Procedure:
Several cardiovascular and general surgeons have agreed to allow procedures to be recorded (digital video and audio recordings) during actual cases. These videos will then be reviewed by a team of researchers to identify any significant “events” that caused errors, treatment delays, miscommunications, disruption of surgical flow, etc., as well as instances of “good” and “not so good” approaches of the surgical team to deal with these events. The ultimate goal is to develop interventions for reducing the occurrence and consequences of errors in the OR that impact patient safety.
Equipment:
Five digital video cameras with microphones are installed in a cardiovascular surgical suite. The signal of the patient monitor is recorded, too. All video and data signals are streamed via TCP/IP Ethernet and broadcasted into the Mayo computer network. All signals are recorded full screen as independent but synchronized video and data files. In addition to the video signals, all kinds of analog (i.e. physiological data of the patient) or digital data can be recorded. Thus the original quality of the source signals is maintained and the researchers are flexible in processing the data after the recording.
The psychologists who observe the team work can watch the video signals from any computer within the Mayo Clinic network.
BIOBSERVE products in use:
Spectator software suite
Digital Recording Box
This is a scheme of the recording system. All signals are streamed via the computer network to the control room.
With the BIOBSERVE Spectator System (BSS) you can record multiple incoming signals in their original quality, acquire and analyze observational data about test participants, measure and rate success and efficiency of task accomplishment, analyze behavioral patterns and compare behaviors of different participants. With the Spectator you can train people for certain tasks and analyze the training's progress and success.
The integrated report generator speeds up the data analysis and can be used to generate customized and standardized documents (i.e. pdf files) and print outs automatically.
As an add on, the BSS can be used in combination with our Audience software. Audience can be used to observe an unlimited number of rooms, connect people from external locations, set up conference calls and interact between different recording sites.
