Abstract(s)
As infeções associadas aos cuidados de saúde têm sido relacionadas com a presença de
microrganismos multirresistentes nas superfícies das Unidades de Saúde. Microrganismos
esses, que aumentam a taxa de morbilidade e mortalidade dos seus clientes. Emerge, por
isso, a necessidade de uma monitorização efetiva e confirmada da higienização das
superfícies que garanta a continuidade dos cuidados sem pôr em risco a segurança do
doente e profissionais de saúde. Mensurar é essencial para planear e adequar as futuras
intervenções. A aplicabilidade de uma escala visual é redutora, por sua vez, o uso do
luminómetro, método ATP, na área da saúde é promissor o controlo da higienização das
superfícies.
Objetivo: Avaliar a eficácia da higiene das superfícies em Unidade de Saúde.
Método: O estudo observacional, prospetivo e analítico, foi realizado no serviço de
Hemodiálise, no decorrer de cinco dias consecutivos, no final do programa de ambulatório.
Foi aplicada uma escala visual e o luminómetro, antes e após a higienização das
superfícies, no final do turno da tarde. O processo de higienização das superfícies, nos cinco
dias correspondentes à colheita, foi realizado pelas mesmas assistentes operacionais do
serviço, recorrendo ao mesmo método e produto (detergente/ desinfetante).
Resultados: A amostra do estudo foi composta por 300 observações (150 antes/ 150 após)
nas áreas touch previamente selecionadas. Das 131 observações, para valor satisfatório, 56
foram mensuradas através do luminómetro e 75 através da escala visual. Para os valores
não satisfatórios, das 169 observações, 94 foram mensuradas pelo luminómetro e 75 pela
escala visual. Após o processo de higienização, das observações correspondentes a valores
não satisfatórios, 31 foram identificadas pelo luminómetro e 18 através da escala visual. Dos
resultados obtidos, infere-se que as diferenças se localizam para valores não satisfatórios (<
500 RLU), no luminómetro e nos valores satisfatórios (> 500 RLU) na escala visual.
Conclusões: No âmbito da saúde, a escala visual e o método de ATP apresentam-se como
métodos complementares. O método ATP funciona como um recurso educacional na
mensuração da qualidade da higienização das superfícies high touch. É um método fácil de
aplicar que permite obter dados quantitativos e imediatos, sendo também um instrumento
poderoso para a formação das assistentes operacionais. O método Visual apresenta como
vantagem a ausência de custos e aplicação de forma sistemática. Urge a necessidade de
um maior número de estudos com intuito de validar a real contribuição do método de ATP na
prevenção das infeções associadas aos cuidados de saúde.

Abstract Infections associated with health care have been related to the presence of multiresistant microorganisms on the surfaces of Health Units. These microorganisms increase the morbidity and mortality rate of their clients. There is therefore a need for effective and confirmed monitoring of surface hygiene that ensures continuity of care without endangering the safety of patients and health professionals. Measuring is essential for planning and tailoring future interventions. The applicability of a visual scale is reducing, in turn, the use of the luminometer, ATP method, in the area of health is promising the control of the hygiene of the surfaces. Background: The study is performed at the Hemodialysis service during five consecutive days at the end of the Hemodialysis program. Objectives: To evaluate the effectiveness of surface hygiene in a health unit. Methods: The observational, prospective and analytical study was performed at the Hemodialysis service, during five consecutive days, at the end of the outpatient program. A visual scale and luminometer were applied before and after surface cleaning at the end of the afternoon shift. The process of cleaning the surfaces during the five days corresponding to the harvest was carried out by the same operating assistants, using the same method and product (detergent / disinfectant). Results: The study sample consisted of 300 observations (150 before / 150 after) in the previously selected touch areas. From the 131 observations, for a satisfactory value, 56 were measured through the luminometer and 75 through the visual scale. For the unsatisfactory values, of the 169 observations, 94 were measured by the luminometer and 75 by the visual scale. After the hygienization process, from the observations corresponding to unsatisfactory values, 31 were identified by the luminometer and 18 through the visual scale. From the results obtained, the differences are found to be unsatisfactory (<500 RLU), luminometer and satisfactory values (> 500 RLU) in the visual scale. Conclusions: In health, the visual scale and ATP method are presented as complementary methods. The ATP method works as an educational resource in measuring the quality of hygiene of high touch surfaces. It is an easy-to-apply method for quantitative and immediate data collection and is a powerful tool for the training of operational assistants. The Visual method presents as an advantage the absence of associated costs and applied in a systematic way. There is a need for a larger number of studies to validate the actual contribution of the ATP method to the prevention of healthcare associated infections.
