Misuse of gloves: the foundation for poor compliance with hand hygiene and potential for microbial transmission?

Improvement in hand hygiene compliance is important for reducing cross-infection by micro-organisms. The objective of this prospective observational study was to measure how the improper use of gloves limits compliance to hand hygiene and exposes patient's to infection. The study was conducted in five wards (three intensive care units and two medical wards) in a French university hospital. Staff-patient and staff-environment contacts were observed in 120 healthcare workers caring for patients colonized or infected with pathogenic bacteria. Hand hygiene was not undertaken due to improper gloving in 64.4% (95%CI, 64.1% to 65.1%) of instances. Possible microbial transmission might have occurred in 18.3% (95%CI, 17.8% to 18.8%) of all contacts because used gloves were not removed before performing care activities that necessitated strict aseptic precautions. Failure to change or remove contaminated gloves was a major component in the poor compliance with hand hygiene and carried a high-risk of microbial transmission. Improving hand hygiene compliance will require changing healthcare workers behaviour towards glove use.

Comparison of systematic versus selective screening for methicillin-resistant Staphylococcus aureus carriage in a high-risk dermatology ward.

OBJECTIVE: To compare two strategies for screening methicillin-resistant Staphylococcus aureus (MRSA) carriers in a high-risk dermatology ward: systematic screening of all admitted patients versus selective screening of patients at risk. DESIGN: The two strategies were applied prospectively during two consecutive periods. In period A (8.5 months), only patients transferred from other wards, or with a history of prior hospitalization, or presenting chronic wounds or disease with denuded skin were considered at high risk of MRSA carriage and sampled. In period B (7.5 months), all admitted patients were systematically screened. End-points were the number of patients having a MRSA-positive screening sample on admission during period B and having none of the risk factors used in period A, the rate of imported MRSA cases, and the rate of acquired cases. SETTING: A 1,032-bed university hospital with a 19-bed inpatient dermatology ward, a referral center for toxic epidermal necrolysis and severe extensive dermatoses. PATIENTS: The study included 729 dermatology inpatients (370 in period A and 359 in period B). RESULTS: During period A, screening samples were obtained on admission for 30% of patients (77% of the patients at risk) and identified 25 MRSA carriers. During period B, 90.5% of admitted patients were screened, and 26 MRSA carriers were detected on admission; all of these patients belonged to at least one predefined category at risk for carriage. Overall rates of imported and acquired cases were similar between the two periods (6.8% vs 7.5%, and 2.9% vs 2.4%, respectively). CONCLUSIONS: A screening strategy targeted to patients at risk of harboring MRSA has similar sensitivity and is more cost-effective than a strategy of systematic screening to identify MRSA carriers on admission.

Selective screening of carriers for control of methicillin-resistant Staphylococcus aureus (MRSA) in high-risk hospital areas with a high level of endemic MRSA.

Screening for methicillin-resistant Staphylococcus aureus (MRSA) carriage in patients at risk was evaluated as part of a control program in a 26-bed medical intensive care unit (ICU) of a university hospital with a high level of endemic MRSA. Control measures included isolation and barrier precautions, skin decolonization with chlorhexidine of patients from whom MRSA was recovered, and mupirocin treatment of nasal carriers of MRSA. Of 3,686 patients admitted during a 4-year period, 44% were screened, which occurred during admission for 38%; MRSA was recovered from 293 patients (8%). There were 150 imported cases and 143 ICU-acquired cases, of which 51% and 45%, respectively, were first identified through screening. Nasal swab cultures identified 84% of MRSA carriers. The incidence of all ICU-acquired cases and of acquired colonization or infection decreased from 5.8% and 5.6% to 2.6% and 1.4% (P = .002 and P < .001), respectively, whereas that of imported cases remained unchanged (range, 3.8% to 4.3%; P = .8). Selective screening for nasal carriage during admission to high-risk areas may contribute to identification of a substantial proportion of cases of MRSA and to early implementation of effective control measures.
