INTRODUCTION:Nursing staff, whether already a professional or in training, is increasingly coming into contact with caregivers who present communication deficits, whether temporary or permanent. People with Complex Communicative Needs (CCB) often require compensatory strategies, such as Alternative Augmentative Communication (AAC). Knowledge of AAC and the systems it makes available already in the training phase is an essential resource for establishing and maintaining an effective therapeutic relationship. AIM:To investigate knowledge and perceptions regarding Augmentative and Alternative Communication in a sample of bachelor nursing students by assessing the effectiveness of a training intervention. METHODS:Pre-post monocentric study with enrolment of a sample of second and third year students of one bachelor school of nursing of the University of Milan; construction and preliminary validation of a questionnaire to detect knowledge and perceptions before and after participation in a training intervention. RESULTS:140 students participated; at T0, 40.0% of the sample was familiar with the CAA; at T1, 92.14%. After the training intervention, the sample's knowledge increased statistically (p < 0.001 for all proposed questions). The questionnaire created showed good validity (CVI-S = 0.93). CONCLUSIONS:It seems desirable to investigate how CAA is also used in different clinical care contexts, to quantify the professionals trained in its use, and to investigate the knowledge of students of other health professions and not., INTRODUZIONE:L’infermiere, già professionista o in fase di formazione, in ogni contesto clinico viene sempre più spesso a contatto con assistiti che presentano deficit di comunicazione, sia temporanei che permanenti. Le persone che presentano Bisogni Comunicativi Complessi (B.C.C.) spesso necessitano dell’adozione di strategie di compensazione, come la Comunicazione Aumentativa Alternativa (C.A.A.). Conoscere la C.A.A. ed i sistemi che essa mette a disposizione già in fase di formazione rappresenta un’importante risorsa per consentire di stabilire e mantenere un’efficace relazione terapeutica. SCOPO:Indagare la conoscenza e la percezione riguardo la Comunicazione Aumentativa ed Alternativa in un campione di studenti del Corso di Laurea in Infermieristica (CLI) valutando l’efficacia di un intervento formativo. METODI:Studio pre-post monocentrico con arruolamento di un campione di studenti di secondo e terzo anno del CLI dell’Università degli Studi di Milano: costruzione e validazione preliminare di un questionario per rilevare le conoscenze e percezioni prima e dopo la partecipazione ad un intervento formativo. RISULTATI:Hanno partecipato 140 studenti; al T0 il 40.0% del campione conosceva la C.A.A., al T1 il 92.14%; successivamente all’intervento formativo le conoscenze del campione sono aumentate in modo statisticamente significativo (p

BACKGROUND: A cross-sectional survey on knowledge and perception of occupational biological risk among workers in several occupations was carried out in the industrial area of Rome. METHODS: The study was carried out in the period of March-April 2010 using a questionnaire with 33 items on the following areas: a) socio-demographic data; b) perception of the biological risks in ordinary occupational activity; c) knowledge about biological risks; d) biological risks in the working environment. The questionnaire was submitted to a convenience sample of workers of an industrial area in Southern Rome. RESULTS: 729 participants entered the study from the following work activities: food, catering, service, farming and breeding, healthcare, school and research (males 57.2%; mean age 37.4 years, SD = 10.9). Significant associations were found between different activity areas with respect to the relevance of the biological risk (p = 0.044) and the perception of the biological risk (p < 0.001). With respect to vehicles of infectious agents, the highest percentages of the most common biological risk exposures were: air and physical contact for the catering and food group, 66.7% and 61.90% respectively; air and blood for the health and research group, with 73.50% and 57.00% respectively; and physical contact and blood for the service group, 63.10 % and 48.30%. Significant difference of proportions were found about the prevalent effect caused by the biological agents was the occurrence of infectious diseases (59.90% food group, 91.60% health and research and 79.30% service group) (p < 0.001). The perception of knowledge resulted in a good rank (sufficient, many or complete) in the food and catering group, 78.3% with significant difference compared to other professions (p < 0.001). CONCLUSIONS: All participants show good knowledge the effects induced by biological agents and it is significant that almost half of the respondents are aware of the risks concerning allergies. Nevertheless, it is surprising that this risk is known mainly by workers of service, farming and breeding, to a greater extent than it is known by health workers.
