No. of bitstreams: 1 HelidaMariaBezerra_DISSERT.pdf: 9931928 bytes, checksum: 26e1ff7ff2ea69cdafbbf8e0db826dbe (MD5) Previous issue date: 2016-10-07 / Objetivo: Aumentar a ades?o ?s pr?ticas de preven??o de pneumonias associadas ? ventila??o mec?nica (PAV) em unidades de terapia intensiva (UTI), atrav?s de um ciclo de melhoria interno. Metodologia: Foi aplicado um ciclo de melhoria da qualidade com desenho quase experimental do tipo antes e depois em duas UTI de um hospital p?blico no nordeste do Brasil, com um total de 19 leitos. Foram estabelecidos nove crit?rios de qualidade relacionados com a preven??o de PAV e um indicador composto com os quais se avaliou o n?vel basal de qualidade e posteriormente mais duas avalia??es subsequentes com intervalos de quatro meses buscando medir as poss?veis melhorias adquiridas nesses per?odos. O Gr?fico de Pareto foi utilizado para representar a frequ?ncia de n?o cumprimentos de cada crit?rio avaliado nos tr?s momentos. Utilizou-se o c?lculo de estima??o pontual e o intervalo de confian?a (95%) para a medi??o dos crit?rios. Para quantificar a efetividade da interven??o, calculou-se a melhoria absoluta e relativa, al?m da significa??o estat?stica da melhoria absoluta mediante o teste unilateral do valor de z. Resultados: Ocorreu uma ligeira melhoria em todos os crit?rios quando comparadas as duas primeiras avalia??es, por?m nesta compara??o inicial, apenas um crit?rio apresentou melhora estatisticamente significante (p<0,05). Na segunda compara??o feita entre a 1? e 3? avalia??es, os resultados revelaram melhora no cumprimento de quase todos os crit?rios, onde dos nove crit?rios estabelecidos, oito obtiveram melhora, sendo seis com melhora estatisticamente significante (p < 0,05), dois com melhora sem signific?ncia e em um crit?rio houve piora no percentual de cumprimento. O indicador composto, que resume todos os crit?rios avaliados, obteve uma melhora significativa de quase 40% (p<0,05) na segunda compara??o. Conclus?es: A implanta??o de ciclos internos de melhoria constitui-se em importante ferramenta de gest?o da qualidade para incorpora??o de boas pr?ticas para preven??o de PAV em UTI. / Objective: To increase adherence of the preventive practices concerning Ventilator-associated pneumonia (VAP) in intensive care units (ICU), through an internal improvement cycle. Methodology: A quality improvement cycle, quasi-experimental design before-after was applied in two ICUs of a public hospital in the northeast of Brazil, with a total of 19 beds. Nine quality criteria related to the prevention of VAP were established and a composite indicator with which to assess the baseline level of quality and later two more subsequent assessments at intervals of four months seeking measure possible improvements acquired during these periods. The Pareto chart was used to represent the frequency of non-compliance of each criterion assessed in three moments. It was used the point estimation and the confidence interval (95%) for the measurement of the criteria. To quantify the effectiveness of the intervention, it calculated the absolute and relative improvement, beyond the statistical significance of the absolute improvement through unilateral test value of z. Results: There was a slight improvement on all criteria when comparing the first two assessments, but this initial comparison, only one criteria showed a statistically significant improvement (p <0.05). In the second comparison between the 1st and 3rd evaluations, the results showed improvement in the performance of all the criteria almost, where the nine established criteria, eight showed improvement, and six with a statistically significant improvement (p <0.05), with two improvement without significance and one criteria has worsened in the percentage of compliance. The composite indicator, which summarizes all the criteria evaluated, obtained a significant improvement of almost 40% (p<0.05) in the second comparison. Conclusions: The implementation of an internal improvement cycle was an important tool in quality management for the adoption of best practices for the prevention of VAP in ICU.
