Abstract

BACKGROUND:

Cell phone use has become common in areas of the hospital, including the operating room. The purpose of this study was to document the frequency of bacterial contamination on the cell phones of orthopaedic surgeons in the operating room and to determine whether a standardized disinfecting protocol decreased the rate of bacterial contamination and the amount of organic material.

METHODS:

Orthopaedic attending and resident cell phones were swabbed on the front and back in the operating room with adenosine triphosphate bioluminescence to quantify organic material contamination and culture swabs to evaluate bacterial contamination. Adenosine triphosphate was quantified with use of relative light units. One photon of light was emitted for each molecule of adenosine triphosphate. Thresholds of 250 and 500 relative light units were used. The phones were cleaned with a cleaning wipe and were retested. One week later, a final set of studies was obtained. Fifty-three participants were enrolled in this study. Pathogenic bacteria were defined as those commonly causing surgical site infections.

RESULTS:

Of fifty-three cell phones, 83% (forty-four cell phones) had pathogenic bacteria at initial testing, 8% (four cell phones) had pathogenic bacteria after disinfection, and 75% (forty cell phones) had pathogenic bacteria one week later. The mean result (and standard deviation) at initial testing was 3488 ± 2998 relative light units, which reduced after disinfection to 200 ± 123 relative light units, indicating a cleaned surface, but increased one week later to 1825 ± 1699 relative light units, indicating a poorly cleaned surface.

CONCLUSIONS:

The cell phones of orthopaedic surgeons had a high rate of pathogenic bacteria and organic material contamination. Both were decreased after a single disinfecting process. However, recontamination occurred. It seems prudent to routinely disinfect them or avoid their use in the operating room.

CLINICAL RELEVANCE:

The current study investigates orthopaedic surgeons’ cell phones as a potential source of nosocomial infection in the operating room. On the basis of the high percentage of cell phone contamination found, we would recommend periodic cell phone cleaning with either the wipes used in our study or similar ones. In addition, given that there was a high contamination rate one week after disinfection, we would recommend considering cell phone cleaning more frequently than once a week.

Los móviles de traumatólogos como posible foco de transmisión de enfermedades.

Un reciente estudio reciente evalúa la posible contaminación de móviles de traumatólogos mediante el estudio microbiológico de su superficie.
De un total de 53 móviles, el 83% tenían bacterias patógenas. Una vez realizada una desinfección con toallita (referenciada en ese estudio), pasaron a ser sólo el 8% los móviles con dichas bacterias.
Al cabo de una semana de la limpieza, el 75% volvía a tener la contaminación patógena.
El estudio resalta una vez más que las manos son el medio de transmisión de muchas enfermedades. Por ejemplo: al evaluar a un paciente ingresado, antes y después tiene que haber una limpieza de manos; si por el contrario, durante el proceso te llaman al teléfono y contestas ya tenemos un posible origen de contaminación (por más que te hayas lavado las manos después).
Considero que la mayoría de infectólogos estaría de acuerdo en que podríamos estar haciendo estudios de iPads, iPhones, mangos de puerta, teclados de ordenador, o carpetas de pacientes, … pero estos estudios reflejan la punta del iceberg de algo más importante. La clave es la limpieza rutinaria de las manos y recordar el lavarse ante de entrar en contacto con superficies que pueden ser reservorio de gérmenes patógenos.
Sin embargo, no está de más la limpieza rutinaria de los objetos que tocan las manos del médico, sea fonendo, martillo o móvil.
