• Registration Number: NCT04725916
• Lead Sponsor: Sean Devitt

Brief Summary

This is a prospective randomized, controlled, unblinded, interventional feasibility study to evaluate if showering with post operative drains in place leads to an increase in complications. The patients included in the study will be those undergoing breast reductions and panniculectomies at Geisinger Medical Center. The patients will be randomized post operatively into one of two groups: 1) patients instructed to shower with drains in place, and 2) patients instructed not to shower while they have drains in place.

Detailed Description

This is a prospective randomized, controlled, unblinded interventional feasibility trial evaluating the post-operative outcomes of surgical patients undergoing breast reduction or panniculectomy procedures. Approximately 100 eligible subjects will undergo their surgical procedure according to standard clinical guidelines. Unless clinically contraindicated, study surgeons will maintain consistent use of 10 Flat drains for all study participants to prevent any sampling bias.

Immediately after surgery is completed, the study investigator will randomize the subject into one of the 2 study arms. The randomization scheme will control for procedure type.

The study will not be blinded. The randomization assignment will be communicated to the care team and documented in the subject's electronic medical record to ensure that appropriate post-operative instruction is provided to the subject. Subjects will be notified of their study arm assignment at the time they receive their post-operative discharge instruction.

Subjects in both arms will complete a questionnaire related to quality of life post-operatively, as well as daily bathing specifics.

The following statistical methods will be used for the aims:

Aim 1: Collect and describe information related to outcome measures in addition to study data including number eligible, response rates, adherence/compliance rates.

Descriptive statistics will be provided for all study enrollment data, compliance information as well as data collected throughout the study including outcome measures and responses from the satisfaction survey.

Aim 2: To compare the surgical site complication rate of post-operative patients with drains who shower versus those who do not shower.

Complication rates between the two study arms will be compared using chi-squared tests, although these comparisons will not be conclusive since the study isn't powered to assess equivalence.

Aim 3: To compare patient post-operative satisfaction for those who shower versus those who do not shower.

Patient post-operative satisfaction between the two study arms will be compared using chi-squared tests, although these comparisons will not be conclusive since the study isn't powered to assess differences.

Arm && Interventions

Group	Intervention	Description
Study Arm 2	Restriction of Showering	Subjects assigned to Arm 2 will be instructed not to shower post-operatively until their surgical drains are removed. They will receive specific instructions on bathing and caring for the incision sites and drains.
Study Arm 1	Showering	Subjects assigned to Arm 1 will be instructed to shower daily beginning on post-operative Day 2 and maintain this daily schedule until the subject's 3-month standard of care clinic follow-up visit. They will receive specific instructions on caring for the incision site and drains until they are removed.

Primary Outcome Measures

Name	Time	Method
Seroma formation	12 weeks	At each post operative visit, the patient will be examined to rule out the presence of wound seroma. Any seroma requiring needle aspiration with removal of fluid will be documented as a positive seroma.
Abscess formation	12 weeks	The patient will be examined at each post operative visit. Any collection of bacteria (abscess) that requires bedside drainage will be recorded as an abscess.
Wound dehiscence	12 weeks	Development of wound dehiscence during follow-up period
Drain site cellulitis	12 weeks	At each post operative appointment, the patient's drain sites will be examined for signs of cellulitis including tenderness to palpation and blanching erythema. The decision will be based on clinical exam by the physicians assistant, confirmed with the attending physician, and photos will be taken for documentation.
Incisional cellulitis	12 weeks	At each post operative appointment, the patient's incision will be examined for signs of cellulitis including tenderness to palpation and blanching erythema. The decision will be based on clinical exam by the physicians assistant, confirmed with the attending physician, and photos will be taken for documentation.
Patient Satisfaction	12 weeks	Measurement of patient satisfaction of post-operative ability to shower based on administration of a satisfaction survey
