Abstract
Introduction: Improper cleaning of surfaces is a contributing factor to inefficiency in infection control in the hospital environment. Objective: To evaluate the effectiveness of the hemodialysis machine cleaning using bioluminescence with the Lightning MVP ICON. Materials and Method: A cross-section study at the Hemodialysis unit of the Hospital Sao Lucas. Samples were collected in 20 machines in three different shifts. The swabs were obtained in 4 pre-determine points, which are: top surface, dialyzer holder, programming and ON/OFF arrows before and after cleaning of equipment, in total were 480 collection points. The reading was held for ATP detection with the Lightning MVP ICON equipment, describing the samples in passed, alert and failure. Results: We found statistically significant differences between evaluations before and after in the case of the programming arrows (p=0.033), where was a significant increase in the rating “passed” after [48.3% (n=29)] when compared to before [25.0% (n=15)]. When the results were compared between shift, the night shift (before: 2.7±1.2 vs. after: 1.0±0.9) had a significantly reduction in the number of failures compared to morning shifts (before: 2.2±1.2 vs. after: 2.0±1.2) and afternoon shift (before: 2.2±1.0 vs. after: 2.1±1.3). Conclusion: The use of the Lightning MVP icon method to evaluate the surface cleaning of the hemodialysis equipment showed a significant decrease in the number of failures after cleaning and sanitizing and significant reduction on number of failures in procedures performed at the night shift when compared to the morning and afternoon shift.

Summary
Avaliação da limpeza de equipamentos de hemodiálise pelo método de Lightning MVP ICON. Mestranda pelo programa de Pós-Graduação da Medicina e Ciências da Saúde – PUCRS. Professor Titular da Faculdade de Medicina e do Programa de Pós-Graduação em Medicina e Ciências da Saúde da PUCRS. Objetivo: Avaliar a limpeza da superfície do equipamento de hemodiálise através do método de bioluminescência com o Lightning MVP ICON, antes e depois da higienização da máquina de hemodiálise. Conclusão: A utilização do método Lightning MVP ICON para avaliação da limpeza da superfície do equipamento de hemodiálise permitiu observar diminuição significativa do número de falhas de limpeza após higienização e ainda redução expressiva do número de falhas nos procedimentos realizados no turno da noite quando comparados com os turnos da manhã e tarde.
