Abstract
Objective: to analyze bacterial growth in samples collected from the hands of health professionals after hygiene with soap and water. Methods: cross-sectional analytical study, carried out with healthcare professionals by collecting samples (print) from the digital pulp of the dominant hand on plates containing chromogenic culture medium for microbiological analysis regarding the presence of colonies. Fisher’s and Chi-square tests were used. Results: 73 samples were collected and 67 (91.8%) showed bacterial growth. Methicillin-resistant Staphylococcus aureus was detected in 19 (26.0%). A significant association between colonies with multidrug-resistance profile and the time of performance (p=0.030) and profession (p=0.041) was highlighted. Conclusion: there was bacterial growth in samples after hand hygiene, with higher growth of multidrug-resistant bacteria among nursing professionals and those with longer time of work. These results may contribute to detect the gaps about the measures adopted for infection prevention.

Summary
Crescimento bacteriano nas mãos dos profissionais de saúde: implicações na prevenção de infecções hospitalares. RESUMO Objetivo: analisar o crescimento bacteriano em amostras coletadas das mãos de profissionais de saúde após higiene com água e sabão. Métodos: estudo transversal analítico, realizado com profissionais de saúde por meio da coleta de amostras (print) das polpas digitais da mão dominante, em placas contendo meio de cultura cromogênico, para análise microbiológica em relação à presença das colônias. Resultados: foram coletadas 73 amostras e 67 (91,8%) apresentaram crescimento bacteriano. Conclusão: houve crescimento bacteriano nas amostras após higiene das mãos, com maior crescimento de bactérias multirresistentes entre profissionais de enfermagem e àqueles com maior tempo de atuação. Estes resultados podem contribuir para detectar as lacunas acerca das medidas adotadas para a prevenção de infeções. Descritores: Crescimento Bacteriano; Pessoal de Saúde; Infecção Hospitalar; Desinfecção das Mãos
