BackgroundHospital beds are potential reservoirs of bacteria in hospitals. Preventing contamination of the bed and providing a cleaner surface should help prevent hospital-acquired infections (HAIs). Most hospital beds are cleaned between patients (terminal cleaning) using quaternary ammonia compounds (quats).ObjectiveThe study had two objectives: identify levels of bacterial contamination on beds (including the mattress and bed deck) and evaluate a new launderable cover.MethodsHospital beds on a bariatric surgery ward were randomized to either receive or not receive a launderable cover (Trinity Guardion, Batesville, IN). Bacterial counts on the surface of the mattress, the bed deck, and the launderable cover were then collected using Petrifilm™ Aerobic Count Plates (Petrifilm™, 3M™, St. Paul, MN, USA) (Petrifilm™) at three time periods (before patient use, after discharge, and after terminal cleaning). Standard hospital linen was used in all rooms.ResultsThe launderable cover (n = 28) was significantly cleaner prior to patient use than were the cleaned mattresses (n = 38) (1.1 CFU/30 cm2 vs. 7.7 CFU/30 cm2; p = 0.0189). The mattresses without launderable covers became significantly contaminated during use (7.7 CFU/30 cm2 on admission vs. 79.1 CFU/30 cm2 after discharge; p < 0.001). The mattresses with launderable covers did not become contaminated (3.0 CFU/30 cm2 on admission vs. 2.5 CFU/30 cm2 at discharge; p = 0.703). After terminal cleaning, the mattress surface contamination decreased to 12.8 CFU/30 cm2 (median 3 CFU/30 cm2; SD 7.8), but the bed deck was more contaminated (6.7 CFU/30 cm2 after discharge compared to 30.9 CFU/30 cm2 after terminal cleaning; p = 0.031).ConclusionsTerminal cleaning fails to eliminate bacteria from the surface of the hospital mattress. The launderable cover provides a cleaner surface than does terminal cleaning with quats, and the cover protects the bed from contamination during use.

“…HAI are usually caused by pathogenic bacteria that may emerge from the patient’s endogenous microflora during antibiotic therapy in approximately 70% of the cases [2,3]. HAI may also be acquired from the exogenous environment (30% of the cases) in that the hospital setting plays a significant role in contagion and transmission outbreaks [3,4].…”

27The hospital environment is an important reservoir of microorganisms, including 28 multidrug-resistant pathogens, which can cause in-patient contamination and healthcare-29 related infections. The objective of this study was to analyze the epidemiology of bacterial 30 contamination (contaminated sites, pathogen species and their antimicrobial 31 susceptibility, and tracking of multidrug-resistant microorganisms -MDR) of inert 32 hospital surfaces and medical equipment in two public hospitals in Northern Brazil. 33 This was a cross-sectional study with 243 samples (n = 208, from Hospital A; and n = 35, 34 from Hospital B) collected by friction with swabs moistened in Brain Heart Infusion from 35 inert surfaces and equipment. The samples were cultivated and bacterial species were 36identified by the classical approach and tested for their susceptibility through agar 37 diffusion assay according to the Clinical and Laboratory Standards Institute (CLSI). 38Most inert surfaces and equipment analyzed presented bacterial contamination (95.5%). 39Staphylococcus aureus was the main pathogen of clinical significance detected both in 40 Hospital A (61.8%) and B (68.6%). Hospital A showed higher rates of isolated MDR 41 bacteria than Hospital B, especially in the Adult Intensive Care Unit, which included 42 methicillin-resistant Staphylococcus aureus (MRSA) (52.7%), Enterobacteria resistant to 43 4 th generation cephalosporins (19.4%), and multidrug-resistant Pseudomonas aeruginosa 44 (2.78%). The failures in the prevention and control of infections in the two hospitals 45 analyzed reinforce the need for a revised protocol for cleaning and disinfection of inert 46 surfaces and medical equipment, and for regulation of antibiotic dispensing, mainly in the 47 AICU of Hospital A, which was found to be a reservoir of MDR pathogens. This study is 48 innovative because it is the pioneer in Western Bahia that describes the epidemiology of 49 contamination of hospital surfaces, opportuning futures studies in this field. 50 Introduction 51Healthcare-associated infections (HAI) are a major public health concern 52 commonly associated with extended length of hospital stay. HAI account for high hospital 53 costs and contribute to increased morbidity and mortality of infected patients [1]. 54HAI are usually caused by pathogenic bacteria that may emerge from the patient's 55 endogenous microflora during antibiotic therapy in approximately 70% of the cases [2,3]. 56HAI may also be acquired from the exogenous environment (30% of the cases) in that the 57 hospital setting plays a significant role in contagion and transmission outbreaks [3,4]. 58In the hospital setting, patients, staff and visitors represent the main reservoir of 59 microorganisms, whereas secondary reservoirs include all environments where nutrients, 60 moisture, and temperature are suitable for microbial survival, such as air humidifiers and 61 nebulizers [5,6]. In addition, dry and inanimate surfaces can also serve as a reservoir of 62 pathogens [3,5,7-9], as in mattre...

“…3,4 Nesse contexto, evidencia-se a importância de uma rotina de limpeza e desinfecção das superfícies dos colchões de forma a reduzir e destruir os microrganismos, além de outros cuidados como: mantê-lo revestido e verificar regularmente a integridade do mesmo e do revestimento, pois a existência de danos no revestimento dos colchões facilita a passagem de microrganismos patogênicos para o seu interior, a qual pode constituir um fator de transmissão de doenças infecciosas.…”

RESUMOEstudo quantitativo, descritivo que teve como objetivo identificar os critérios para aquisição, conservação e descarte de colchões utilizados em hospitais e instituições de longa permanência para idosos. Participaram do estudo 11 hospitais e sete instituições de longa permanência para idosos. Os dados foram obtidos por meio de questionário com questões objetivas referentes à caracterização da instituição, à aquisição, à conservação e ao descarte de colchões, que foi respondido por profissionais de saúde. A maioria das instituições adquiriu colchões por meio de compra direta do fornecedor (72%) e realizava avaliação periódica da integridade do colchão e do seu revestimento (94%) durante a higienização concorrente da unidade do paciente. Quanto ao destino final dos colchões, 11% dos hospitais descartavam em resíduo contaminado e 11% em resíduo comum; já nas instituições de longa permanência para idosos, 17% armazenavam os colchões na própria instituição, 17% realizavam doação e 17% tinham os colchões recolhidos e descartados por serviços terceirizados. Os participantes do estudo expressaram dificuldade e desconhecimento quanto à manutenção e descarte dos colchões, portanto, é pertinente que órgãos reguladores instituam normas específicas para o controle desse dispositivo médico-hospitalar.
