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.

An antibiotic policy associated with reduced risk of Clostridium difficile-associated diarrhoea.

BACKGROUND: antibiotic-associated diarrhoea caused by Clostridium difficile is increasing in hospitals, and older people are at particular risk. OBJECTIVE: to establish whether reducing patient exposure to injectable third-generation cephalosporins by substituting alternative antibiotics can produce a cost-effective reduction in the incidence of antibiotic-associated diarrhoea. DESIGN: we prospectively investigated 2157 patients admitted to the department of elderly medicine in the year before introduction of antibiotic restrictions and 2037 patients admitted in the following year. Patients admitted to other wards, where antibiotic prescribing was unchanged, acted as controls. SETTING: a 900-bed teaching hospital in Cambridge, UK. MEASUREMENTS: use and cost of injectable antibiotics prescribed in the department of elderly medicine and the other wards studied; occurrence of C. difficile-associated diarrhoea. RESULTS: in the wards for older people, consumption of injectable cephalosporins fell by 92% (compared with 8% on other wards) and cases of C. difficile-associated diarrhoea fell from 98 to 45 (cases in other wards rose from 213 to 253; P < 0.001). The Pound Sterling 8062 increase in injectable antibiotic costs on the elderly wards were offset by the release of 1087 wasted bed-days attributable to the 53 fewer cases, with potential savings of Pound Sterling 212,000. CONCLUSIONS: restricting the consumption of injectable third-generation cephalosporins is a cost-effective method of reducing the incidence of C. difficile-associated diarrhoea.

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.

Dispose of disposables?

We investigated the implications of a change from disposable to regular crockery and cutlery, and the installation of a dishwasher on a 12-bedded-infectious diseases ward. A limited microbiological study of used disposable cutlery revealed contamination by methicillin-resistant Staphylococcus aureus of one utensil out of 12. Changing to conventional utensils could be recommended if a dishwasher meeting DHSS requirements was installed and safe working practices introduced.

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.

An analysis of infection control of varicella-zoster virus infections in Addenbrooke's Hospital Cambridge over a 5-year period, 1987-92.

This prospective study analyses infections with varicella-zoster virus (VZV) in Addenbrooke's Hospital, Cambridge during 1987-92 and examines the spread of infection. In total, 93 patients and staff experienced VZV infection. Twenty-one patients had varicella and 49 experienced zoster. None of 101 patients and 1 of 625 staff members in contact with varicella cases acquired infection. By contrast, 2 of 227 patients, and 5 of 1039 staff in contact with zoster cases acquired varicella. One out of 28 (3.6%) VZV antibody-negative patients and staff in contact with varicella acquired infection, compared with 5 out of 29 (17.2%) VZV antibody-negative patients and staff in contact with zoster. Thus, zoster was found to be a more frequent cause of nosocomial infection than varicella. Fourteen members of staff had VZV infection during the study period. One of 99 patients and none of 389 staff members in contact with these cases developed varicella. The cost of dealing with infection control for VZV infections in our hospital is estimated to be Pounds 714 per patient case and a total of Pounds 13,204 per year.
