Patient experience of preheated and room temperature skin disinfection prior to cardiac device implantation: A randomised controlled trial

Abstract

Background:

Clinically, patients often comment on the coolness of the skin disinfectant. However, scarce evidence is available regarding patients’ experience during intraoperative skin disinfection.

Aims:

The aim of this study was to describe and compare intraoperative patient experiences with preheated and room temperature skin disinfectant.

Method:

This randomised controlled trial included 220 patients undergoing cardiac device implantation. Patients allocated to preheated (36°C) or room temperature (20°C) chlorhexidine in 70% ethanol verbally answered an open-ended question regarding their experience with the skin disinfection. Results were assessed using a qualitative approach with comparative quantification.

Results:

The analysis resulted in nine categories describing the patients’ experiences with preheated and room temperature skin disinfection. Most of the patients described the skin disinfection process as a negative experience, which consisted of six categories: cold, smell, change in temperature, unpleasant, wet and painful. In addition, two neutral categories of response (nothing in particular and neither pleasant nor unpleasant) and one positive response (pleasant) emerged through the analysis. Preheated skin disinfection yielded significantly fewer negative experiences in the category cold (85% vs. 15%, P<0.0001) and significantly more positive experiences (66% vs. 34%, P<0.002). Neutral categories (neither pleasant nor unpleasant 65% vs. 35%, P=0.01, nothing in particular 74% vs. 26%, P<0.001) dominated after preheated skin disinfection.

Conclusion:

The use of preheated skin disinfection promotes a positive patient experience with skin disinfection.
