Staphylococcus epidermidis is a versatile agent, being both a commensal and a nosocomial pathogen usually with an opportunistic role in association with implanted foreign body materials. Pre-operative antiseptic preparation is an important strategy for reducing the risk of complications such as surgical site infection (SSI). Currently, the most widely used antiseptics are alcohols, quaternary ammonium compounds (QACs), and the bisbiguanide chlorhexidine. Occurrence of resistance to the latter agent has drawn increasing attention. The aim of this study was to investigate if decreased susceptibility to chlorhexidine among S. epidermidis was present in our setting, a Swedish university hospital. Staphylococcus epidermidis (n = 143), retrospectively collected, were obtained from prosthetic joint infections (PJI) (n = 61), post-operative infections after cardiac surgery (n = 31), and the skin of the chest after routine disinfection prior to cardiac surgery (n = 27). In addition, 24 commensal isolates were included. Minimum inhibitory concentration (MIC) of chlorhexidine was determined on Mueller Hinton agar plates supplemented with serial dilutions of chlorhexidine. Five QAC resistance genes, qacA/B, smr, qacH, qacJ, and qacG, were detected using PCR. Decreased susceptibility to chlorhexidine was found in 54% of PJI isolates, 68% of cardiac isolates, 21% of commensal isolates, and 7% of skin isolates from cardiac patients, respectively. The qacA/B gene was present in 62/143 isolates (43%), smr in 8/143 (6%), and qacH in one isolate (0.7%). The qacA/B gene was found in 52% of PJI isolates, 61% of cardiac isolates, 25% of commensal isolates, and 19% of the skin isolates. In conclusion, decreased susceptibility to chlorhexidine, as well as QAC resistance genes, were prevalent among S. epidermidis isolates associated with deep SSIs.

Aim To discuss specialist operating theatre nurses’ competence in relation to the general six core competencies and patient safety. Design A discursive analysis of legal statutes and scientific articles. Methods Swedish legal statutes and an overview of scientific articles on operating theatre nursing were deductively analysed and classified into healthcare providers’ general six core competencies. Results All healthcare professionals should possess the general core competencies, regardless of their discipline. The specific content within these competencies differs between disciplines. The specialized operating theatre nurse is the only healthcare professional having the competence to be responsible for asepsis, instrumentation, infection and complication, control and management of biological specimens during the surgical procedure. Besides operating theatre nurses, no other healthcare profession has the formal education, competence or skills to perform operating theatre nursing care in the theatre during the surgical procedure. Operating theatre nurse competence is therefore indispensable to ensure patient safety during surgery.

Psychometric testing of the Swedish translation of the PPCS-R suggests a good construct validity, and the construct and its six factors are conceptually relevant among the Swedish OR nurses and RNAs.

To standardize OR nurses' preventive interventions, implementing guidelines seems to be the key priority. Overall, OR nurses have high compliance with the national guidelines regarding interventions to prevent bacterial growth and SSIs in the surgical patient. However, when guidelines are lacking, the preventive interventions lose conformity.

BackgroundThroughout many countries, professional bodies rely on yearly self-assessment of competence for ongoing registration; therefore, nursing competence is pivotal to safe clinical practice. Our aim was to describe and compare perioperative nurses’ perceptions of competence in four countries, while examining the effect of specialist education and years of experience in the operating room.MethodsWe conducted a secondary analysis of cross-sectional surveys from four countries including; Australia, Canada, Scotland, and Sweden. The 40-item Perceived Perioperative Competence Scale-Revised (PPCS-R), was used with a total sample of 768 respondents. We used a factorial design to examine the influence of country, years of experience in the operating room and specialist education on nurses’ reported perceived perioperative competence.ResultsRegardless of country origin, nurses with specialist qualifications reported higher perceived perioperative competence when compared to nurses without specialist education. However, cross-country differences were dependent on nurses’ number of years of experience in the operating room. Nurses from Sweden with 6–10 years of experience in the operating room reported lower perceived perioperative competence when compared to Australian nurses. In comparing nurses with > 10 years of experience, Swedish nurses reported significantly lower perceived perioperative competence when compared to nurses from Australia, Canada and Scotland.ConclusionResearchers need to consider educational level and years of experience in the perioperative context when examining constructs such as competence.

Surgical site contamination, for example, with coagulase-negative staphylococci, probably derives from both the patient's own skin flora and those of the surgical team. Despite preoperative antiseptic preparation with chlorhexidine solution, complete sterilization of the skin is not possible and gradual recolonization will occur. Plastic adhesive drape is an established method used to prevent direct wound contamination from adjacent skin. In this study, the time to skin recolonization after antiseptic preparation was measured and the impact of using plastic adhesive drape on this recolonization was evaluated. Repeated bacterial sampling using three different methods over 6 hr was conducted after antiseptic preparation in 10 volunteers. Recolonization of skin was observed after 30 min with plastic drape and after 60 min without plastic drape; there were significantly more positive cultures with the plastic drape than without (31% vs. 7.5%, respectively, p < .001). Sampling with a rayon swab was the most sensitive sampling method. In conclusion, covering the skin with a plastic adhesive drape seems to hasten recolonization of the skin after antiseptic preparation. However, clinical trials to confirm this finding are warranted.
