Answers linked to Lepelletier D, Lucet JC. Controlling meticillin-susceptible Staphylococcus aureus (MSSA) e not simply MRSA revisited. J Hosp Infect 2013;84:13e21. Available online 7 June 2013
1. In cardiac surgery, what is the proportion of endogenous S. aureus among all S. aureus responsible for surgical site infection? (a) (b) (c) (d) (e)
20%. 40%. 60%. 80%. Almost 100%. Answer: (d).
2. MSSA and MRSA may differ for several epidemiological characteristics. Which of the following statements is false? (a) MRSA carriers are at higher risk for S. aureus infection than MSSA carriers. (b) MRSA may be more easily transmitted between patients in the hospital than MSSA. (c) The success of eradication with topical antimicrobials is similar for MRSA and MSSA. (d) Antibiotic exposure generally increases the burden of MRSA and decreases the burden of MSSA. Answer: (c). 3. Which of the following statements apply to nasal MSSA decolonization with mupirocin? (a) Nasal carriage is eliminated in 100% of patients who received mupirocin. (b) The objective of the nasal decolonization is to obtain a transient suppression at the time at risk rather than to eradicate carriage definitively.
(c) Nasal decolonization should be started at least one or two days before the surgical procedure. (d) Universal nasal decolonization may be a cost-saving alternative in comparison with a strategy including systematic screening for nasal carriage and decolonization of nasal carriers only. Answers: (b), (c), (d). 4. Which of the following statements apply to MSSA carriage? (a) Nasal carriage is permanent in w20% of the patients at hospital admission. (b) The anterior nares are the exclusive site of carriage. (c) Gastrointestinal carriage without nasal carriage can be found in 10e30% of the patients. (d) Throat carriage without nasal carriage can be found in 10e30% of the patients. Answers: (a), (c), (d). 5. Which of the following statements apply to MSSA decolonization? (a) Mupirocin is the exclusive topical drug that can be used for nasal decolonization. (b) Daily perioperative shower with antiseptic soap is usually recommended in combination with nasal mupirocin during the decolonization period. (c) Resistance to mupirocin is common after use of mupirocin. (d) Nasal decolonization generally leads to the MSSA cutaneous decolonization. Answers: (b), (d).
Summarising the instructions from the Royal College of Pathologists: (1) One CPD point is allowed for each question and answer set (up to five questions and answers). (2) Answers must be recorded referenced back to the questions and recorded in the CPD portfolio. (3) It is essential that participants include the completed response form showing both questions and answers in their portfolio as these may be subject to audit by RCPath.
