[The seasonal flu vaccination among caregivers in geriatric units: Up-to-date]. / La couverture vaccinale contre la grippe saisonnière du personnel soignant en gériatrie : mise au point.

BACKGROUND: Flu vaccinations for healthcare professionals seems to be one of the most effective preventive actions in the face of a disease that carries a high risk of a potentially serious nosocomial epidemic in a geriatric environment. The aim of this study was to take stock of the flu vaccination status among caregivers in the geriatric units and to understand the reasons for their reluctance to be vaccinated, in order to put forward proposals to improve vaccination coverage. METHOD: A literature search of articles published since 2000 in the area of geriatrics, infectious diseases or pneumology was mainly conducted on PubMed using the keywords "caregivers", "elderly", "flu", "influenza", "nosocomial" and "vaccination". After reading all abstracts in English or French and ruling out irrelevant articles, only 64 relevant articles have been listed in bibliography section. RESULTS: Despite official recommendations, the literature reveals insufficient vaccination coverage of healthcare personnel at both the national and international level. Vaccination coverage seems to be lower among younger female non-medical staff. The factors that determine the likelihood of vaccination are the wish to protect one's self, one's family and patients/residents, as well as the experience of earlier bouts of flu. Factors that oppose vaccination are complex and related to the fear of side effects, the use of other preventive measures, the feeling that vaccination is ineffective, poor understanding of the disease and the vaccine, forgetfulness and problems of organization. Campaigns to promote vaccination that target healthcare professionals must be multidimensional and very incentive. The pedagogical message must be centered on the benefits to the individual and adjusted to socio-professional categories. Mobile strategies in the different departments to encourage staff are a pragmatic solution to this challenge. The referring doctor has an essential role to play, as does the occupational doctor in association with the hospital hygiene services. CONCLUSION: Flu vaccinations must be included in the education and training of caregivers.

Impact of microbiological samples in the hospital management of community-acquired, nursing home-acquired and hospital-acquired pneumonia in older patients.

We investigated the positivity rate, the detection rates for non-covered pathogens and the therapeutic impact of microbiological samples (MS) in community-acquired pneumonia (CAP), nursing home-acquired pneumonia (NHAP) and hospital-acquired pneumonia (HAP) in elderly hospitalised patients. Patients aged 75 years and over with pneumonia and hospitalised between 1/1/2013 and 30/6/2013 in the departments of medicine (5) and intensive care (1) of our university hospital were included. Microbiological findings, intra-hospital mortality and one-year mortality were recorded. Among the 217 patients included, there were 138 CAP, 56 NHAP and 23 HAP. MS were performed in 89.9, 91.1 and 95.6 % of CAP, NHAP and HAP, respectively. Microbiological diagnosis was made for 29, 11.8 and 27.3 % of patients for CAP, NHAP and HAP, respectively (p = 0.05). Non-covered pathogens were detected for 8 % of CAP, 2 % of NHAP and 13.6 % of HAP (p = 0.1). The antimicrobial spectrum was significantly more frequently reduced when the MS were positive (46.7 % vs. 10.8 % when MS were negative, p = 10(-7)). The MS positivity rate was significantly lower in NHAP than in CAP and HAP. MS revealed non-covered pathogens in only 2 % of NHAP. These results show the poor efficiency and weak clinical impact of MS in the management of pneumonia in hospitalised older patients and suggest that their use should be rationalised.

[Low vaccination coverage against influenza in elderly hospitalized in France]. / Faible taux de couverture vaccinale contre la grippe des sujets âgés hospitalisés en France.

PURPOSE: Annual influenza epidemics is still a major cause of illness and mortality especially in the elderly. Annual vaccination is the most effective way to prevent disease and reduce hospitalizations and deaths related to influenza in the elderly population. In France, there are few data available about vaccination coverage of elderly at risk for influenza. The aim of the study was to measure the influenza vaccination coverage and assess traceability in the elderly (≥ 75 years old) admitted to hospital. METHODS: In participating French hospitals, each patient aged 75 years or more, hospitalized in acute units of internal medicine, geriatric and infectious disease, was included in a multicentric point prevalence survey. RESULTS: Between April and May 2011, 63 departments of 28 hospitals participated and 903 patients were included (mean age of included patients: 85 years): 82% were previously living at home and 13% were institutionalized. Most of them had multiple diseases (77%) and 21% were admitted for a respiratory disease: 58% were vaccinated against influenza. A back-up for traceability was identified in 53% of cases. Patient refusal may be a common determinant of non-vaccination, as well as non-proposal by the attending physician. The vaccination rate did not differ according to usual living place including accommodation facilities in geriatric. CONCLUSION: Coverage for influenza vaccination is low in hospitalized elderly patients and traceability is insufficient. This vaccine, noncompliance mostly linked to the refusal of patients, is a worrisome public health problem, on which physicians and hospital staff in charge, as well as institutions, should turn attention toward a multi-professional preventive strategy against the morbidity risk of this infectious disease.

Successful management of heparin-induced thrombocytopenia using argatroban in a very old woman: a case report.

Thrombosis due to heparin-induced thrombocytopenia (HIT) is rare but has a severe prognosis. Its management is not always easy, particularly in old patients with renal insufficiency. A 95-year-old woman was hospitalized for dyspnea. Curative treatment with unfractionated heparin was started because pulmonary embolism was suspected. Disseminated intravascular coagulation was then suspected because of thrombocytopenia, hypoprothrombinemia, hypofibrinogenemia, and a positive ethanol gelation test. The first immunoassay for HIT was negative. On the 12th day of hospitalization, bilateral cyanosis of the toes occurred associated with recent deep bilateral venous and arterial thrombosis at duplex ultrasound. New biological tests confirmed HIT and led us to stop heparin and to start argatroban with a positive clinical and biological evolution. Venous and arterial thrombosis associated with thrombocytopenia during heparin treatment must be considered HIT whatever the biological test results are. Argatroban is a good alternative treatment in the elderly.

Streptococcus pneumoniae vaccinal coverage in hospitalized elderly patients in France.

BACKGROUND: In France, there is little data on vaccinal coverage in elderly people at risk for invasive pneumococcal infections (IPI). OBJECTIVE: The study objective was to assess the pneumococcal vaccination coverage and traceability in hospitalized elderly people (>75 years of age). METHOD: A multicentric point prevalence survey was made on volunteers over 75 years of age, hospitalized in internal medicine, geriatrics, and infectious diseases units. RESULTS: Nine hundred and three patients in 63 units of 28 hospitals were included (mean 85 years of age) in the study between April and May 2011. Ten percent (93/903) were vaccinated against the pneumococcus. Thirty-eight percent of the patients had at least one risk factor for IPI and 20.5% of these had been vaccinated. There was a traceability back-up in 59% of the cases. Vaccination was not considered by the hospital for 83% of patients with IPI risk factor but not vaccinated (task delegated to the family physician in 50% of the cases). CONCLUSION: Vaccination coverage against the pneumococcus in France is very low in hospitalized patients over 75 years of age even though more than one out of three presents at least one risk factor for IPI. The rate of traceability is also poor. Hospitalization should be an opportunity to offer pneumococcal vaccination to elderly patients at risk for IPI in France because of unclear recommendations for elderly individuals and lack of political will to improve vaccination coverage.
