Point prevalence survey of healthcare-associated infections and use of antimicrobials in Irish intellectual disability long-term care facilities: 2013.

BACKGROUND: Healthcare-associated infections (HCAIs) and use of antimicrobials are prevalent in long-term care facilities (LTCFs), but few data are available on the burden of these issues in intellectual disability (ID) LTCFs. AIM: To assess the prevalence of HCAIs and use of antimicrobials in Irish ID-LTCFs to plan future HCAI prevention programmes. METHODS: A national point prevalence survey was conducted in Irish ID-LTCFs in May 2013 using a European protocol. All Irish ID-LTCFs with full-time residents were invited to participate in this voluntary survey. Data were collected locally and analysed at the national coordinating centre. RESULTS: Twenty-four Irish ID-LTCFs participated, with 1060 residents surveyed, representing 42% of ID-LTCF residents in Ireland. The crude HCAI prevalence rate was 4.3% (median 2.2, range 0-46.7), with respiratory tract infections (1.6%) and skin infections (1.6%) being the most prevalent types. Antimicrobials were prescribed for 10% of eligible residents (median 7.5, range 3.2-13.9), with 49% of all prescriptions indicated for prophylaxis. Prevention of urinary tract infections (38%), respiratory tract infections (36%) and skin infections (27%) were the most common reasons for prophylaxis. There was considerable variation in the prevalence of prescribing for prophylaxis across ID-LTCFs (range 2-29%), with only 17% of facilities having local antimicrobial guidelines in place. CONCLUSION: There is a considerable burden of HCAIs and use of antimicrobials, particularly for skin and respiratory tract infections, in Irish ID-LTCFs. Further surveillance in this population is needed to help guide preventive strategies for ID-LTCF residents at risk of these infections.

Healthcare-associated infections and antimicrobial use in long-term care facilities: the Irish experience with the HALT surveys.

In the context of an ageing European population, point prevalence surveys (PPS) of healthcare-associated infection and antimicrobial use in long-term care facilities (HALT) in Europe were commissioned by the European Centre for Disease Prevention and Control. Sixty-nine Irish long-term care facilities (LTCFs) took part in the first survey in 2010. A series of interventions to raise the profile of infection prevention and control and antimicrobial stewardship in Irish LTCFs followed. HALT was repeated in Ireland in 2011, with 108 participating LTCFs, and again in 2013 as part of the second European HALT survey, with 190 participating LTCFs. The latest Irish HALT report incorporates data from the three PPSs to date, and discusses the findings and the national implementation priorities recommended by the Irish multi-disciplinary steering group. Ireland contributed ∼10% of the total resident population in both of the European HALT PPSs. This, and the growing number of participating LTCFs, shows that healthcare professionals in Irish LTCFs are committed to improving the quality and safety of resident care.

Thoracic spinal cord lesions are influenced by the degree of cervical spine involvement in multiple sclerosis.

STUDY DESIGN: Cross-sectional analyses. OBJECTIVE: To determine whether cervical spinal cord lesions predict the presence of thoracic cord lesions in multiple sclerosis (MS) patients. SETTING: Single MS Clinic, AZ, USA. METHODS: All MS patients, with MRI studies of the brain, cervical and thoracic spine obtained during a single scanning session, were acquired during a 1-year period. Clinical, demographic and imaging covariates were used in a multivariate regression model to refine predictors of thoracic cord involvement. RESULTS: A total of 687 patients were evaluated, and patients were excluded because of a diagnosis of other neurological disorders, not meeting the 2010 McDonald criteria for MS (n=222) or incomplete neuraxis imaging (n=339). The study cohort comprised 126 patients. There was an increase in the odds ratio (OR) of thoracic spine involvement when any cervical spine lesion was present (OR=6.08, 95% confidence interval (2.21-16.68), P<0.001). The multivariate logistic regression model demonstrated a substantial and significant increase in the odds of thoracic spine involvement when more than two cervical spine lesions were present, two lesions (OR 4.44, (0.91-21.60), P=0.06), three lesions (OR 19.76, (3.51-111.17), P=0.001), four or more lesions (OR 20.49, (1.97-213.23), P=0.012) and diffuse lesions (OR 71.94, (5.28-979.88), P=0.001), when adjusting for significant covariates including clinical symptoms, brain lesions, disease duration and treatment exposure. CONCLUSIONS: Thoracic spinal cord lesions appear to be predicated on the degree of cervical spine involvement in patients with MS, a risk that appears to be independent of brain findings or clinical features.

Healthcare-associated infection in Irish long-term care facilities: results from the First National Prevalence Study.

BACKGROUND: Prevalence of healthcare-associated infection (HCAI) and antimicrobial use in Irish long-term care facilities (LTCFs) has never been studied. AIM: To collect baseline data on HCAI prevalence and antibiotic use in Irish LTCFs to inform national LTCF policy and plan future HCAI prevention programmes. METHODS: A prevalence study of HCAI and antibiotic use was undertaken in Irish LTCFs. Participation was voluntary. Data on HCAI risk factors, signs and symptoms of infection and antimicrobial use were collected prospectively on a single day in each institution. FINDINGS: Sixty-nine Irish LTCFs participated and 4170 eligible residents were surveyed; 472 (11.3%) had signs/symptoms of infection (266, 6.4%) and/or were on antibiotics (426, 10.2%). A third of residents (1430, 34.3%) were aged ≥85 years and more than half disorientated (2110, 50.6%) with impaired mobility (2101, 50.4%). HCAI prevalence was 3.7% (range: 0-22.2%). The most common HCAI was urinary tract infection (UTI) (62 residents, 40% of HCAI). Presence of a urinary catheter was associated with UTI (P < 0.0000001). Antibiotics were prescribed for treatment (262 residents, 57.8%) and prophylaxis (182 residents, 40.2%) of infection. The most common indication for prophylaxis was UTI prevention (35.8% of total prescriptions). Fourteen (10.2%) residents on UTI prophylaxis had a urinary catheter. The most common indications for therapy included respiratory tract infections (35.1%), UTI (32.1%) and skin infection (21.8%). CONCLUSION: This study highlights the frequency of prophylactic antimicrobial prescribing and provides an important baseline to inform future preventive strategies.

A 12-year review of Staphylococcus aureus bloodstream infections in haemodialysis patients: more work to be done.

Staphylococcus aureus bloodstream infections (BSI) are a significant cause of morbidity and mortality in haemodialysis patients. This study describes a 12-year retrospective review of S. aureus BSI in a large haemodialysis centre in a tertiary referral hospital. The overall rate of S. aureus BSI was 17.9 per 100 patient-years (range 9.7-36.8). The rate of meticillin-resistant S. aureus (MRSA) BSI was 5.6 per 100 patient-years (range 0.9-13.8). Infective complications occurred in 11% of episodes, the most common being infective endocarditis (7.6%). Ten percent of patients died within 30 days of S. aureus being isolated from blood. Most cases of S. aureus BSI (83%) were related to vascular catheters. The provision of lower-risk vascular access, such as arteriovenous fistulae, and reduced use of intravascular catheters should be priorities in all haemodialysis units. Where alternative vascular access cannot be established, interventions to reduce the risk of catheter-related infections should be implemented to reduce morbidity and mortality in this vulnerable patient group.

Treatment of a thyrotropinoma with octreotide-LAR in a patient with multiple endocrine neoplasia-1.

OBJECTIVE: To note that a thyrotropin (TSH)-secreting macroadenoma may be part of the multiple endocrine neoplasia-1 (MEN-1) syndrome and to report the use of octreotide-LAR (OCT-LAR) to treat a TSH-secreting macroadenoma in a patient with MEN-1 with previous surgery for hyperparathyroidism and gastrinoma. METHODS: We present a patient with a TSH-secreting pituitary macroadenoma and report the results of her endocrine, genetic, radiologic, and nuclear medicine testing and her response to treatment with octreotide (OCT), octreotide-LAR, and estrogen. RESULTS: This patient's TSH-induced hyperthyroidism responded to octreotide for 5 months and octreotide-LAR for more than 11 months. Her hypercalcemia normalized while she was taking estrogen. Her genetic testing is reported to show a genetic defect that is typical of patients with MEN-1. CONCLUSION: This report describes: (1) The use of octreotide-LAR to treat both a TSH-secreting pituitary tumor and a gastrinoma over 12 months; (2) the importance of including these tumors into the MEN-1 syndrome with its attendant implications; and (3) a genetic defect, typical of patients with MEN-1, associated with this tumor.
