Contaminated sharps injuries (including needlesticks) can result in infection with hepatitis B,
C and HIV. Though this is rare, these injuries can cause great anxiety to health care and
other staff who encounter used needles in the course of their work. Prevention of exposure to oneself and others requires clinical healthcare workers (needle users) to observe good practice at all times. The concept of the ‘Hierarchy of Risk Controls’ (see page 2), widely used in the practice of occupational health and safety, is a useful model for sharps injury prevention. The controls at the top of the list are more effective than those at the bottom e.g. PPE requires compliant behaviour by the user which can only be achieved with good Standard Precautions (an example of an administrative control) must be implemented on
each occasion that a needle / sharp is used in clinical care. Assume all patients are potentially infected with a blood borne virus Prepare carefully for the task with appropriate PPE and equipment. Seek assistance if you have concerns about the patient’s ability to cooperate. You, as the user, are responsible for the disposal of the sharp. Dispose of sharp immediately after use by bringing Cin bin to point of care. Do not place sharp in kidney dish or other ‘interim’ container. Do not resheath needles, or manipulate them by hand. Take care when passing sharp instruments to colleagues HIERARCHY OF RISK CONTROLS

Measles is an acute viral illness, which is highly contagious and is spread by coughing and
sneezing. One case of measles can infect 15 – 20 unvaccinated people. Transmission of measles is by droplet infection. The virus can remain viable on infected surfaces for up to 2 hours. The incubation period is 10 days (range 7 - 18 days) with a further 2 - 4 days before the rash appears. Patients are infectious from 4 - 5 days before to 4 days after the onset of
What are the symptoms of Measles?
Symptoms occur several days before the rash begins. These can include: 1. High fever (up to 105°F or 40.6°C) 2. Hacking cough 9. Small red lesions with blue - white centres (known as Koplik’s spots appearing on The early symptoms usually disappear 1 - 2 days after the rash appears. The rash is a red, blotchy rash that usually appears about 14 days after exposure to the virus and lasts 5 - 6 days. Measles can occur in late teens and young adults. The rash will be itchy and spreads from the head and chest downward to the rest of the body. Other symptoms in adults may include sensitivity to light, diarrhoea and earache.
How do I diagnose and manage measles?
Diagnosis is usually made from a combination of the symptoms, especially the rash and the
presence of small white spots visible in the mouth. No specific treatment so treatment focuses on relieving the symptoms. Where possible all individuals should be treated at home. Only children and adults who develop severe complications should be admitted to hospital. If this is the case, it is important to let
the hospital know that you suspect measles, as the patient needs to be isolated in

a single room on admission and only attended to by staff that have immunity to

The majority of people recover, however 30% of individuals will develop a complication,
which is more common in children under 5 years of age and in adults over 20 years of age The complications are: Fatality rate is highest in children under 1 year, lowest in those aged 1 - 9 and rises again in teenagers and adults. Pneumonia accounts for 56 - 86% of measles-associated deaths.
The best prevention for measles is vaccination. This is in the form of MMR vaccine given to children at 12 - 15 months of age, with a second dose at 4 - 5 years of age. For older children who have not received 2 doses, MMR vaccine should be given as soon as possible. During measles outbreaks all susceptible individuals should be immunised within 72 hours of contact, and if these individuals have had no previous vaccine, a second dose should be

Ms. Aileen O' Brien, Infection Control/Communicable Disease Nurse Manager, Department of Public
HSE, Dr Steevens Hospital.
Outbreaks of C. difficile can lead to severe illness and sometimes death for patients, and to
serious disruptions for staff and service provision. The risk of outbreak occurrence can be minimised by following some simple and practical steps: 1. Vigilance / early detection
• Educate staff about C. difficile infection to facilitate early identification of possible • Test the stools of patients with diarrhoea for C. diff. Diarrhoea is defined as
three or more loose/watery bowel movements that take up the shape of
their container (which are unusual or different for the patient) in a 24 hour

• Keep a stool chart for patients with diarrhoea, e.g. Bristol stool chart. • Tell your local infection control nurse (if applicable) about new cases. ISOLATE PATIENTS AS SOON AS THEY DEVELOP DIARRHOEA.
2. Notification
• Notify confirmed cases of ‘Clostridium difficile associated disease*’ (see case definition) to the Department of Public Health in Dr Steevens Hospital, by telephone   CASE DEFINITION: A confirmed C. difficile associated disease (CDAD)* case is a patient
ears or older, to whom one or more of the following criteria applies:
• Diarrhoeal stools or toxic mega colon, with either a positive laboratory assay for C. difficile toxin A cdA) and / or toxin B (TcdB) in stools or a toxin-producing C. difficile organism detected in stool • Pseudomembranous colitis (PMC) revealed by lower gastrointestinal endoscopy. • Colo nic histopathology characteristic of C. difficile infection (with or without diarrhoea) on a specimen obtained during endoscopy, colectomy or autopsy. 3. Treatment
• The recommended first line treatment for symptomatic non-severe C. difficile infection is oral Metronidazole 400mgs three times daily for ten days. • See national guidelines for the treatment of recurrences or reinfection or seek advice 4. Infection control
• Isolate symptomatic patients in single rooms with clinical hand washing sink and ensuite facilities, or provide a designated toilet / commode (patient should not use ward general toilet facilities) until they are at least 48 hours symptom free (have a formed or normal stool for that patient). Cohort patients, when isolation facilities are not available. • Reinforce standard and contact precautions and provide written guidelines to staff. • Review the patient’s clinical condition and antibiotic regimen – and stop inappropriate • Wear apron and gloves for patient contact. Remove these immediately following patient contact and wash hands using liquid soap and water.
• Clean the environment with detergent and water and disinfect with a chlorine
based disinfectant at 1000ppm available chlorine at least daily, e.g. liquid
hypochlorite or sodium dichloroiscyanurate (NADCC) tablets. • Use dedicated equipment for cases, e.g. commodes, slings, blood pressure cuffs. • Ensure that bedpan washers are in good working order and that bedpans and commodes are kept meticulously clean at all times – see sluice room audit tool in this 5. Appropriate antibiotic prescribing
• Antibiotic prescribing (types of agents and duration) should be reviewed with local prescribers with the aim of reducing inappropriate use of broad-spectrum antibiotics. This is particularly important where there is an increase in the number of cases of C.
When to suspect an outbreak?

An outbreak is defined as the occurrence of two or more linked CDAD cases over a specific period of time, taking account of the usual rate or where the current number of CDAD cases exceeds the expected number. A risk assessment needs to be performed where there are two or more cases within an eight week period to determine if the cases are linked (i.e. cross infection has occurred). In hospital settings this will be carried out by the local infection control team. In community settings, e.g. nursing homes and residential care facilities, the Department of Public Health should be contacted for infection control advice and guidance. When an outbreak of CDAD is suspected, an outbreak control team (OCT) should be established. The decision to convene an OCT will be made by the Hospital CEO or general manager / network manager or the PCCC local health office manager, on the advice of the Consultant Medical Microbiologist or the Medical Officer of Health (MOH) in the Department of

Antimicrobial consumption in Dublin/North East region in 2009
Ms. Sarah Foley, Antimicrobial Pharmacist, Beaumont Hospital.
Throughout 2007 to 2009 antimicrobial use in the Dublin and North East region has been
consistently less than national consumption levels, whilst also following national seasonal
variation trends (Figure 1). Antimicrobial consumption is measured in defined daily doses per 1000 inhabitants per day (DID). In the Dublin and North East region the ‘Top 5’ most commonly prescribed antibiotics were co-amoxiclav (26.8%), amoxicillin (16%), clarithromycin (14.4%), doxycycline (5.8%) and flucloxacillin (4.6%) respectively (see Figure
2). In 2009, the highest consumption of antibiotics occurred in Louth. The DID for the
county was 26.4 compared to a national consumption rate of 21.8. In the remaining regions
the defined daily dose per 1000 inhabitants was Dublin city (20), Fingal (16.8), Monaghan (24.5), Cavan (22.3) and Meath (17). Figure 3
