Traditional Lecture Versus Procedural Video

Day 1 - 6 to 8 hours:

The study will be performed at Carilion Roanoke Community Hospital. Participants will be enrolled in a study to evaluate traditional lecture versus an asynchronous micro-video for teaching baclofen pump refilling and programming skills. Demographic information will be collected for each participant (table 1). Six education sessions will be conducted with ten participants per session. The duration of the session will be six to eight hours. All participants will perform pre-intervention baclofen pump refilling and programming in the simulated environment graded using a rubric for baclofen pump management. A SynchroMed II baclofen pump simulator will be used to simulate baclofen pump refilling and programming during the study. The participant will interrogate the pump, refill the pump with simulated intrathecal baclofen, and program the pump by increasing the daily rate of intrathecal baclofen by 10%. The scenarios used for the study will be the same for all simulations. Subjects will be tested individually to eliminate any group practice effects of observing other subjects testing. The rubric will be graded and recorded by one consistent investigator. The rubric has a minimum score of 0.5 and a maximum score of 10, with four steps referred to as "fatal flaws" that must be completed correctly to receive a passing score. A passing score on the rubric is a 9/10 with no "fatal flaws." The rubric for baclofen pump management has been studied in physical medicine \& rehabilitation residents, and non-published data showed a mean evaluation score and experience refilling and programming baclofen pumps to be highly correlated (Pearson coefficient = 0.899, p-value = 0.0489). Cronbach's alpha was calculated and was 0.91 showing good internal consistency.

Participants will be randomly allocated to either the micro-video intervention group or the traditional lecture control group. Randomization would be done using the random number generator formula in Microsoft Excel. They would be informed of their group allocation. The participants will not be blinded as they would come to know if they are placed in the intervention or the control group. Group A (n=30) will receive a baclofen pump refill and programming instruction via the traditional lecture method performed by a single faculty member. The traditional lecture will consist of a PowerPoint lecture for 30 minutes, a demonstration of the refilling and programming technique for 10 minutes, and participant hands-on practice refilling and programming a baclofen pump for 20 minutes. Group A will have time to practice refilling and programming baclofen pumps with the guidance of a single faculty member during the traditional 60-minute lecture. In contrast, Group B (n=30) will receive an asynchronous 10-minute micro-video on the topic for which no face-to-face interaction with faculty will be conducted. The micro-video will be provided on a 12.9-inch iPad pro for each participant to view individually. The micro-video group will also have the opportunity to practice pump refilling before the post-evaluation. Participants in Group B will have the micro-video instruction available while practicing hands-on baclofen pump refilling and programming. The maximum time allowed to view the micro-video and practice hands-on baclofen pump refilling and programming will be 30-minutes. The time that each participant in group B spends reviewing the micro-video and practicing hands-on pump refilling and programming will be recorded. The participant may view and rewind the video as many times as needed in the 30-minute period. The live demonstration and the procedural video describe identical steps involved in refilling and programming the baclofen pump.

The participants from both groups will then be subjected to post-intervention baclofen pump refilling and programming graded with the same rubric following exposure to the traditional lecture or asynchronous micro-video. The investigator that provided initial pre-intervention baclofen pump rubric grading will assess baclofen refilling and programming for both groups according to pre-specified criteria in the rubric. The investigator providing evaluation will be blinded to the instructional method. Subjects will be tested individually to eliminate any group practice effects of observing other subjects while testing. Rubric scoring will be recorded for both groups.

Day 2 - 4 to 5 hour:

Between six and eight weeks after the initial intervention, participants from both groups will perform a second post-intervention baclofen pump refilling and programming on a simulated patient with the same blinded investigator during six sessions of ten subjects each. This session will occur at Carilion Roanoke Community Hospital and will last four to five hours. Participants will be graded with the same rubric to see if knowledge was retained. Rubric scoring will be recorded for both groups. Subjects will be tested individually to eliminate any group practice effects of observing other subjects while testing. A traditional 60-minute lecture for Group B will follow the second post-intervention baclofen pump refilling and programming, and the asynchronous micro-video will be shared with Group A.

Following exposure to both methods of instruction, participants will provide feedback on the learning methods using structured focus groups (figure 1). Six focus group sessions will be performed with the ten subjects in each education session. Each focus group will last about 30 minutes to minimize participants' fatigue. One of the study investigators will serve as a trained moderator will lead the qualitative, semi-structured group interview to assess their overall experiences with traditional lecture versus an asynchronous micro-video (Appendix B). This will include new information learned by participants during the study, including discussing participant learning preferences that may inform future education practice for filling and programming baclofen pumps. The focus groups will be recorded and transcribed verbatim.
