Effects on nursing workload of different methicillin-resistant Staphylococcus aureus (MRSA) control strategies.

Nursing staff workload may influence hospital-acquired staphylococcal transmission. Closure of wards to new admissions is used in some institutions as part of methicillin-resistant Staphylococcus aureus (MRSA) outbreak control, and we postulated that it worked by reducing staff workload, allowing more time for good infection control practices. We have used the GRASPCopyright workload system to compare nursing workload during six MRSA outbreaks. Two outbreaks occurred while an aggressive control policy ('old'; 1994-1995) was in place, with a low threshold for ward closure. Control measures had been relaxed before the later four outbreaks, with wards remaining fully or partially open unless MRSA transmission proved intractable ('new'; 1995-1996). To standardize the analysis we compared GRASP and epidemiological data for periods while MRSA transmission was occurring on each ward ('during'), and four week periods 'before' and 'after'. Closing wards to admissions reduces staff workload towards a quality environment, although the nursing requirements of remaining patient rises. Workload pressures may rise during outbreaks if wards are not closed quickly and fully, and patients are not transferred to specialist isolation facilities. Changes in nursing workload need to be assessed during comparative studies of outbreak control measures and the GRASP(c) system appears to be a sensitive way to measure these.

Scissors: are they an infection control risk?

Increasing bacterial resistance means that nurses must re-examine infection control procedures. Bacteria were cultured from 59% of scissors swabbed. Some were still contaminated after cleaning. Some nurses do not appear to recognise the risk of infection from using their scissors for a variety of purposes.

Winning the battle but losing the war: methicillin-resistant Staphylococcus aureus (MRSA) infection at a teaching hospital.

A methicillin-resistant Staphylococcus aureus (MRSA) control policy, aimed at eradication, was established at a 1000-bed hospital in 1985, applied consistently for 10.5 years, and then relaxed. Its components included screening of high-risk patients, transfer of carriers to exhaust-ventilated isolation rooms, closure of wards to new admissions when local transmission was detected, MRSA screening during outbreaks, and prospective collection of clinical and epidemiological information. During the eradication policy period, every 6 months, a mean of 5.1 patients (range 1-12) already carrying MRSA were admitted, and a mean of 3.6 (range 0-16) acquired carriage in the hospital. The largest outbreak comprised 11 patients despite epidemic MRSA strain EMRSA-16 being introduced six times, and MRSA did not become endemic. MRSA-positive admissions increased progressively from 1993; nursing staff workload increased, areas available for alternative patient accommodation were reduced, the resulting ward closures interfered with clinical services, and hence the control policy was relaxed in mid-1995. Isolation facilities were overwhelmed with 622 new patient-isolates in the next 18 months, and there were 67 clinical infections in 1996. The proportion of blood cultures positive for MRSA rose nearly sevenfold by 1996 and 27-fold by 1997. Thus, repeated eradication of MRSA, even epidemic strains, by use of a stringent policy, is possible given sufficient resources, whereas flexible national guidelines designed to control, but not eradicate, epidemic staphylococci, are currently unlikely to be successful. The costs of eradication policies need to be weighed against those of endemicity.

Financial burden of hospital-acquired Clostridium difficile infection.

Clostridium difficile infection has become endemic in many hospitals and yet few data on the associated costs of such cases are available. We prospectively followed 50 consecutive cases of C. difficile infection and 92 control patients, who were admitted to the same geriatric wards within 72 h of the cases. Cases and controls had similar age, sex and major diagnosis distributions. Cases stayed significantly longer (mean 21.3 days, median 20.5 days; P < 0.001) in hospital than controls, including an average 14 days in a side room. Diarrhoea developed in cases on average 10.8 days after admission, which, when compared with a mean duration of stay for controls of 25.2 days, implies that C. difficile infection caused an increased duration of stay, as opposed to infection occurring because of longer residence. There was a significantly higher death rate in cases compared with controls (P < 0.01). Antibiotic treatment of C. difficile infection cost an average of Pounds 47 per case. The average number of laboratory investigations per day was similar for cases and controls, but the increased length of stay meant an extra cost for tests of approximately Pounds 210 per case. Assuming hotel costs of Pounds 150 (Pounds 200) per day stay (in a side room), 94% of the additional costs associated with C. difficile infection were due to increased duration of stay (Pounds 3850). The total identifiable increased cost of C. difficile infection was, therefore, in excess of Pounds 4000 per case. Such high costs can be used to justify expenditure on personnel and/or other control measures to reduce the incidence of this hospital-acquired infection.
