CONOSCENZA E PRATICA DELLE PRECAUZIONI STANDARD TRA I LAVORATORI SANITARI NELL’AREA OVEST DELLA CITTÀ DI LUSAKA

Riassunto. Introduzione. Nei paesi a basso reddito le precauzioni standard (SP) sono spesso praticate parzialmente esponendo gli operatori sanitari a un rischio di infezione evitabile (1). Scopo di questo studio è quello di investigare il livello di compliance con le SP tra gli operatori sanitari di strutture sanitarie di Lusaka. Materiali e Metodi. Lo studio è stato condotto da febbraio ad aprile 2016 in 44 lavoratori(23 uomini, 21 donne) di 9 strutture sanitarie della città di Lusaka. Per esaminare la consapevolezza e la conoscenza delle SP è stato consegnato ai lavoratori un questionario mirato e autosomministrabile, sviluppato in inglese dopo un approfondito esame della letteratura riferita all’Africa sub-sahariana (2,3). Il questionario comprende 43 domande su: dati socio-demografici; conoscenze sulla prevenzione delle infezioni; pratica dei lavoratori nella prevenzione delle infezioni Risultati. Solo il 47,8% dei lavoratori maschi vs 85,7% delle lavoratrici non indossa lo stesso paio di guanti per più pazienti, anche in assenza di contaminazione visibile (p=0.0114). La prevalenza dell’esposizione da taglio è significativamente maggiore nelle donne rispetto agli uomini (p=0.0144), senza differenze per l’esposizione muco cutanea. La prevalenza di infortuni biologici per reincappucciamento delle siringhe è maggiore nel sesso femminile (p=0.0001). Meno del 30% dei lavoratori dei due sessi pratica la profilassi post-esposizione. Una percentuale significativamente minore di lavoratrici rispetto ai lavoratori pratica disinfezione con alcool (p=0.0396). Le lavoratrici più dei lavoratori percepiscono le SP come impedimento allo svolgimento del lavoro (p=0.0420). I lavoratori di sesso maschile ritengono che la finalità delle precauzioni sia di proteggere il personale sanitario (p=0.0018); la protezione dei pazienti dall’essere infettati dal personale sanitario è considerata più rilevante dagli uomini (p=0.0291) così come la protezione del personale nella manipolazione di rifiuti infettivi e taglienti (p=0.0022 e p=0.0001). Conclusioni. I nostri dati evidenziano una grave sottovalutazione del rischio biologico. La percezione delle SP e del rischio lavorativo nel contesto studiato, ci inducono a ritenere che, la sicurezza sul lavoro non faccia parte dello svolgimento delle mansioni ordinarie ma sia piuttosto un corpo normativo “calato dall’alto”

Risk factors for three-month mortality after discharge in a cohort of non-oncologic hospitalized elderly patients: Results from the REPOSI study

Background: Short-term prognosis, e.g. mortality at three months, has many important implications in planning the overall management of patients, particularly non-oncologic patients in order to avoid futile practices. The aims of this study were: i) to investigate the risk of three-month mortality after discharge from internal medicine and geriatric wards of non-oncologic patients with at least one of the following conditions: permanent bedridden status during the hospital stay; severely reduced kidney function; hypoalbuminemia; hospital admissions in the previous six months; severe dementia; ii) to establish the absolute risk difference of three-month mortality of bedridden compared to non-bedridden patients. Methods: This prospective cohort study was run in 102 Italian internal medicine and geriatric hospital wards. The sample included all patients with three-months follow-up data. Bedridden condition was defined as the inability to walk or stand upright during the whole hospital stay. The following parameters were also recorded: estimated GFR <= 29 mL/min/1.73 m(2); severe dementia; albuminemia << 2.5 g/dL; hospital admissions in the six months before the index admission. Results: Of 3915 patients eligible for the analysis, three-month follow-up were available for 2058, who were included in the study. Bedridden patients were 112 and the absolute risk difference of mortality at three months was 0.13 (CI 95% 0.08-0.19, p << 0.0001). Logistic regression analysis also adjusted for age, sex, number of drugs and comorbidity index found that bedridden condition (OR 2.10, CI 95% 1.12-3.94), severely reduced kidney function (OR 2.27, CI 95% 1.22-4.21), hospital admission in the previous six months (OR 1.96, CI 95% 1.22-3.14), severe dementia (with total or severe physical dependence) (OR 4.16, CI 95% 2.39-7.25) and hypoalbuminemia (OR 2.47, CI 95% 1.12-5.44) were significantly associated with higher risk of three-month mortality. Conclusions: Bedridden status, severely reduced kidney function, recent hospital admissions, severe dementia and hypoalbuminemia were associated with higher risk of three-month mortality in non-oncologic patients after discharge from internal medicine and geriatric hospital wards

Implementation of the Frailty Index in hospitalized older patients: Results from the REPOSI register

Background: Frailty is a state of increased vulnerability to stressors, associated to poor health outcomes. The aim of this study was to design and introduce a Frailty Index (FI; according to the age-related accumulation of deficit model) in a large cohort of hospitalized older persons, in order to benefit from its capacity to comprehensively weight the risk profile of the individual. Methods: Patients aged 65 and older enrolled in the REPOSI register from 2010 to 2016 were considered in the present analyses. Variables recorded at the hospital admission (including socio-demographic, physical, cognitive, functional and clinical factors) were used to compute the FI. The prognostic impact of the FI on in-hospital and 12-month mortality was assessed. Results: Among the 4488 patients of the REPOSI register, 3847 were considered eligible for a 34-item FI computation. The median FI in the sample was 0.27 (interquartile range 0.21\u20130.37). The FI was significantly predictive of both in-hospital (OR 1.61, 95%CI 1.38\u20131.87) and overall (HR 1.46, 95%CI 1.32\u20131.62) mortality, also after adjustment for age and sex. Conclusions: The FI confirms its strong predictive value for negative outcomes. Its implementation in cohort studies (including those conducted in the hospital setting) may provide useful information for better weighting the complexity of the older person and accordingly design personalized interventions

Prevalence and Determinants of the Use of Lipid-Lowering Agents in a Population of Older Hospitalized Patients: the Findings from the REPOSI (REgistro POliterapie Societ\ue0 Italiana di Medicina Interna) Study

Background: Older patients are prone to multimorbidity and polypharmacy, with an inherent risk of adverse events and drug interactions. To the best of our knowledge, available information on the appropriateness of lipid-lowering treatment is extremely limited. Aim: The aim of the present study was to quantify and characterize lipid-lowering drug use in a population of complex in-hospital older patients. Methods: We analyzed data from 87 units of internal medicine or geriatric medicine in the REPOSI (Registro Politerapie della Societ\ue0 Italiana di Medicina Interna) study, with reference to the 2010 and 2012 patient cohorts. Lipid-lowering drug use was closely correlated with the clinical profiles, including multimorbidity markers and polypharmacy. Results: 2171 patients aged >65\ua0years were enrolled (1057 males, 1114 females, mean age 78.6\ua0years). The patients treated with lipid-lowering drugs amounted to 508 subjects (23.4%), with no gender difference. Atorvastatin (39.3%) and simvastatin (34.0%) were the most widely used statin drugs. Likelihood of treatment was associated with polypharmacy ( 655\ua0drugs) and with higher Cumulative Illness Rating Scale (CIRS) score. At logistic regression analysis, the presence of coronary heart disease, peripheral vascular disease, and hypertension were significantly correlated with lipid-lowering drug use, whereas age showed an inverse correlation. Diabetes was not associated with drug treatment. Conclusions: In this in-hospital cohort, the use of lipid-lowering agents was mainly driven by patients\u2019 clinical history, most notably the presence of clinically overt manifestations of atherosclerosis. Increasing age seems to be associated with lower prescription rates. This might be indicative of cautious behavior towards a potentially toxic treatment regimen

Choice and Outcomes of Rate Control versus Rhythm Control in Elderly Patients with Atrial Fibrillation: A Report from the REPOSI Study

Background: Among rate-control or rhythm-control strategies, there is conflicting evidence as to which is the best management approach for non-valvular atrial fibrillation (AF) in elderly patients. Design: We performed an ancillary analysis from the \u2018Registro Politerapie SIMI\u2019 study, enrolling elderly inpatients from internal medicine and geriatric wards. Methods: We considered patients enrolled from 2008 to 2014 with an AF diagnosis at admission, treated with a rate-control-only or rhythm-control-only strategy. Results: Among 1114 patients, 241 (21.6%) were managed with observation only and 122 (11%) were managed with both the rate- and rhythm-control approaches. Of the remaining 751 patients, 626 (83.4%) were managed with a rate-control-only strategy and 125 (16.6%) were managed with a rhythm-control-only strategy. Rate-control-managed patients were older (p\ua0=\ua00.002), had a higher Short Blessed Test (SBT; p\ua0=\ua00.022) and a lower Barthel Index (p\ua0=\ua00.047). Polypharmacy (p\ua0=\ua00.001), heart failure (p\ua0=\ua00.005) and diabetes (p\ua0=\ua00.016) were more prevalent among these patients. Median CHA2DS2-VASc score was higher among rate-control-managed patients (p\ua0=\ua00.001). SBT [odds ratio (OR) 0.97, 95% confidence interval (CI) 0.94\u20131.00, p\ua0=\ua00.037], diabetes (OR 0.48, 95% CI 0.26\u20130.87, p\ua0=\ua00.016) and polypharmacy (OR 0.58, 95% CI 0.34\u20130.99, p\ua0=\ua00.045) were negatively associated with a rhythm-control strategy. At follow-up, no difference was found between rate- and rhythm-control strategies for cardiovascular (CV) and all-cause deaths (6.1 vs. 5.6%, p\ua0=\ua00.89; and 15.9 vs. 14.1%, p\ua0=\ua00.70, respectively). Conclusion: A rate-control strategy is the most widely used among elderly AF patients with multiple comorbidities and polypharmacy. No differences were evident in CV death and all-cause death at follow-up
