1241. Marked Improvement in Post-Operative Craniotomy Wound Care Using 2% Chlorhexidine (CHG) Cloths for Blood Clots Removal and Hair Cleaning in a Photo-Documentation Survey

Abstract Background Post-operative wound care can be an important strategy to prevent surgical site infection (SSI) following craniotomy. Insufficient wound care, blood clots, and oily hair near the incision can increase SSI risk. Methods We conducted a pre-post prospective cohort evaluation of a quality improvement intervention to address inpatient post-operative craniotomy wounds at an academic hospital. A post-op wound care protocol was jointly developed by neurosurgical wound care nurses, clinicians, and infection preventionists. The protocol began on postoperative day 1, and included use of soft ties to keep adjacent hair away from the incision, use of 2% CHG cloths to clean skin and hair within 2 inches of the incision as well as the proximal 6 inches of any surgical drain, and use of 2% CHG cloths to remove blood clots. Selection of 2% CHG cloths for blood clot removal was made following comparison to several concentrations of peroxide. A twice-weekly photo-survey of all inpatients undergoing craniotomy was undertaken during the baseline period (October–December 2018) and intervention period (March–April 2019), with feedback to wound care nurses occurring during the intervention period only. The proportion of redness, extensive blood clots (>50% incision), and oily hair near the incision were compared between the baseline period and the intervention period using Fisher’s exact tests. Results A total of 156 photo assessments were performed in 71 patients (101 assessments in 45 patients in the baseline period, and 55 photo assessments in 26 patients in the intervention period). Demographics, body mass index, emergent status, and prior craniotomy were similar across the baseline and intervention periods. The intervention was associated with significant reductions in redness (27.7% vs. 11%, P = 0.015), blood clots (33.7% vs. 10.9%, P = 0.002), and oily hair near the incision (76.7% vs. 28.6%, P < 0.001) (Figure 1). Conclusion The care of post-operative craniotomy wounds and adjacent hair was significantly improved through a standardized protocol to remove blood clots and ensure clean skin and hair adjacent to the incision during the post-operative inpatient stay. Photo documentation and feedback to wound care nurses helped ensure protocol adherence. Disclosures All authors: No reported disclosures.
