SECONDARY outcome

Timeframe: 2 weeks

Comparison of complication rate, including dehiscence, necrosis, maceration, and seromas between treatment groups. These are gathered via the patient's medical chart and interaction with the Principle Investigator (their physician).

SECONDARY outcome

Timeframe: 2 weeks

Differences in quantitative patient survey responses regarding acceptability. This scale includes three subscales: 1) comfort, 2) difficulty with mobilization, and 3) pain at surgical site. Each subscale is graded on a scale of 1-5 with 1 being "better" (i.e. very comfortable, no difficulty, or no pain) and 5 being "worse" (i.e. very uncomfortable, extreme difficulty, or extreme pain). Subscales will be combined to compute a total score by averaging the sum of each of the three subscales. The total score indicates patient acceptability on a scale of 1-5 with 1 being "better" (very acceptable) and 5 being "worse" (not acceptable).

SECONDARY outcome

Timeframe: 2 weeks

Differences in quantitative nurse survey responses regarding acceptability and tolerance of each therapeutic modality, including patient comfort. This survey includes three subscales: 1) ease of use, 2) amount of training required, and 3) Time Required for Troubleshooting or Otherwise Occupied by Device. Each subscale is graded on a scale of 1-5 with 1 being "better" (i.e. no difficulty, no training, or no time) and 5 being "worse" (i.e. extreme difficulty, very high amount of training, or \>30 minutes a day). Subscales will be combined to compute a total score by averaging the sum of each of the three subscales. The total score indicates nurse acceptability on a scale of 1-5 with 1 being "better" (very acceptable) and 5 being "worse" (not acceptable).
