Legionella control in the water system of antiquated hospital buildings by shock and continuous hyperchlorination: 5 years experience

To control the presence of Legionella in an old hospital water system, an integrated strategy of water disinfection-filtration was implemented in the university hospital Umberto I in Rome. Due to antiquated buildings, hospital water system design and hospital extension (38 buildings), shock hyperchlorination (sodium hypochlorite, 20-50 ppm of free chlorine at distal points for 1-2 h) followed by continuous hyperchlorination (0.5-1.0 mg/L at distal points) were adopted, and microbiological and chemical monitoring of the water supply was carried out in the university hospital (December 2006-December 2011). Overall, 1308 samples of cold 45°C (17.8%) water were collected, determining residual free chlorine (0.43 ± 0.44 mg/L), pH (7.43 ± 0.29) and trihalomethanes (8.97 ± 18.56 μg/L). Legionella was isolated in 102 (9.8%) out of 1.041 water samples without filters (L. pneumophila sg 1 17.6%, L. pneumophila sg 2-14 28.4%, L. non pneumophila 53.9%), and in none of the 267 samples with filters. Legionella was recovered in 23 buildings out of 38 and 29 samples (28.4%) exceeded 103 cfu/L. When considering the disinfection treatment Legionella was isolated: before shock hyperchlorination (21.1%), 15 days after shock hyperchlorination (7.8%), 30 days after shock hyperchlorination (3.5%), during continuous hyperchlorination (5.5%) and without continuous hyperchlorination (27.3%). Continuous hyperchlorination following the shock treatment achieved >70% reduction of positive samples, whereas no continuous hyperchlorination after shock treatment was more frequently associated to Legionella isolation (OR 6.41; 95% CI 3.10-13.26; p 0.5 < 1.0 mg/L) deteriorated water quality (organoleptic and chemical). However, shock and continuous hyperchlorination remains a valid-term option in old buildings with no water system rational design, managing problems due to hospital extension and absence of a proper hot water recirculation system

Prevalence, associated factors and outcomes of pressure injuries in adult intensive care unit patients: the DecubICUs study

Funder: European Society of Intensive Care Medicine; doi: http://dx.doi.org/10.13039/501100013347Funder: Flemish Society for Critical Care NursesAbstract: Purpose: Intensive care unit (ICU) patients are particularly susceptible to developing pressure injuries. Epidemiologic data is however unavailable. We aimed to provide an international picture of the extent of pressure injuries and factors associated with ICU-acquired pressure injuries in adult ICU patients. Methods: International 1-day point-prevalence study; follow-up for outcome assessment until hospital discharge (maximum 12 weeks). Factors associated with ICU-acquired pressure injury and hospital mortality were assessed by generalised linear mixed-effects regression analysis. Results: Data from 13,254 patients in 1117 ICUs (90 countries) revealed 6747 pressure injuries; 3997 (59.2%) were ICU-acquired. Overall prevalence was 26.6% (95% confidence interval [CI] 25.9–27.3). ICU-acquired prevalence was 16.2% (95% CI 15.6–16.8). Sacrum (37%) and heels (19.5%) were most affected. Factors independently associated with ICU-acquired pressure injuries were older age, male sex, being underweight, emergency surgery, higher Simplified Acute Physiology Score II, Braden score 3 days, comorbidities (chronic obstructive pulmonary disease, immunodeficiency), organ support (renal replacement, mechanical ventilation on ICU admission), and being in a low or lower-middle income-economy. Gradually increasing associations with mortality were identified for increasing severity of pressure injury: stage I (odds ratio [OR] 1.5; 95% CI 1.2–1.8), stage II (OR 1.6; 95% CI 1.4–1.9), and stage III or worse (OR 2.8; 95% CI 2.3–3.3). Conclusion: Pressure injuries are common in adult ICU patients. ICU-acquired pressure injuries are associated with mainly intrinsic factors and mortality. Optimal care standards, increased awareness, appropriate resource allocation, and further research into optimal prevention are pivotal to tackle this important patient safety threat

Facial nerve paralysis in children

Facial nerve palsy is a condition with several implications, particularly when occurring in childhood. It represents a serious clinical problem as it causes significant concerns in doctors because of its etiology, its treatment options and its outcome, as well as in little patients and their parents, because of functional and aesthetic outcomes. There are several described causes of facial nerve paralysis in children, as it can be congenital (due to delivery traumas and genetic or malformative diseases) or acquired (due to infective,inflammatory, neoplastic, traumatic or iatrogenic causes). Nonetheless, in approximately 40%-75% of the cases, the cause of unilateral facial paralysis still remains idiopathic. A careful diagnostic workout and differential diagnosis are particularly recommended in case of pediatric facial nerve palsy, in order to establish the most appropriate treatment, as the therapeutic approach differs in relation to the etiology

Informazione: risultati di un'indagine di monitoraggio nella stagione del "caso fluad"

INTRODUZIONE: L’influenza è una patologia di rilevante impatto sanitario, economico e sociale. Nonostante l’offerta del vaccino ai gruppi a rischio, le coperture in Italia rimangono molto al di sotto dei target stabiliti dal Ministero. I mezzi di informazione di massa sono potenti strumenti per convogliare messaggi di educazione sanitaria rivolti alla popolazione generale. Obiettivo del nostro studio è stato valutare analiticamente l’eco mediatico del “caso Fluad”. METODI: L’analisi è stata effettuata su 365 numeri de “Il Corriere della Sera” (dal 14/05/14), screenati per la presenza di parole chiave e di articoli inerenti il tema della patologia influenzale e della vaccinazione. Per ciascun articolo incluso sono stati analizzati: rilevanza, posizione, numero di parole. Per le parole chiave è stato valutato il trend temporale di frequenza in relazione all’inizio della campagna vaccinale e al caso Fluad. RISULTATI: In 12 mesi le parole legate al concetto di ‘patologia influenzale’ sono apparse 273 volte. Di queste solo il 9% al lancio della campagna vaccinale (ottobre), contro il 30% tra il 28/11 e il 2/12, giorni nei quali si è verificato il caso Fluad. 89 sono stati gli articoli rilevanti pubblicati: il 53% su influenza e vaccinazione, il 17% su vaccinazioni in generale, il 9% su altre vaccinazioni e il 21% su argomenti di sanità pubblica con soli accenni alle vaccinazioni. Dei 47 articoli su influenza e vaccinazione il 45% (n=21) è stato pubblicato tra il 28/11 e il 2/12. Di questi, il 67% è stato pubblicato prima della smentita ufficiale di AIFA e ISS sulla responsabilità vaccinale dei decessi, con 3 articoli in prima pagina e una lunghezza media del 25% maggiore rispetto alla media totale. Nessun articolo è stato pubblicato all’uscita della circolare Ministeriale sulle raccomandazioni per la stagione influenzale. DISCUSSIONE: Proponiamo un modello analitico di monitoraggio dei media quale strumento utile per studiarne l’impatto sui comportamenti della popolazione in tema di salute e prevenzione. L’ISS ha stimato che le coperture della vaccinazione antinfluenzale siano calate drasticamente in seguito al caso Fluad. I risultati preliminari del nostro studio dimostrano come i mezzi di informazione siano stati principali mediatori di quest’associazione

[Re-organization of health services in Italy and the role of medical directors of hospitals and local health units]

Health authorities, medical directors and managers are called to face increasing and inter-related challenges regarding the ongoing financial crisis, aging of the population and the need to acquire innovative medical technologies. These challenges need to be tackled in order to ensure sustainability of the healthcare systems and appropriateness and quality of healthcare services. In Italy, the role of medical directors has progressively evolved over the years and now requires strengthened managerial skills and additional professional expertise and skills to plan, implement and evaluate the new systems of government. We performed an extensive literature review and a qualitative study involving six semi-structured interviews with key actors (health managers) in order to explore and clarify the possible future role of medical directors in Italy and what training should be provided to residents in Hygiene and Preventive Medicine

Antibiotic resistance as a major public health concern: epidemiology and economic impact

Antimicrobial resistance (AMR) is mainly sustained by the improper use of antibiotics and has become a global public health concern both in the field of human and animal health. Italy has the highest prevalence of AMR among European countries, in particular carbapenem-resistant Klebsiella pneumoniae, which reached 34.3% in 2013. Multidrug-resistant microorganisms' infections are associated with increased risk of complications, higher hospitalization rates, increased healthcare costs, loss of productivity and increased mortality. This paper summarizes the most recent epidemiological data regarding the spread of antibiotic resistance in Italy, consumption and economic impact, outlining the need for timely action and integrated approaches in all countries
