Biosafety of Musical Instruments in the ICU

Introduction: Nosocomial infections can negatively affect the recovery and well-being of patients. Music therapy is a profession that uses music and sounds to improve the health, well-being and quality of life of patients. Musical instruments are regularly used in music therapy sessions, such as the string or percussion instruments, among others. Since the musical instruments are also played and handled by the patients, the question arises if the disinfection and cleaning protocol for musical instruments of the music therapy service at the University Hospital Fundación Santa Fe de Bogotá (FSFB) is effective and safe.

Objectives: To establish the effectiveness and impact of the disinfection protocol of musical instruments used by the music therapy service in the ICUs of the FSFB.

Methodology: This is a study carried out in 2 phases. The first phase corresponds to an experimental design in which the presence of microbiological viability will be evaluated through ATP bioluminescence tests and cultures before and after the application of the disinfection and cleaning protocol in a controlled environment. The second phase corresponds to a prospective cohort study in which music therapy patients will be followed up ver a period of two months, determining the impact of the disinfection and cleaning protocol.

Analysis: A descriptive analysis will be applied where the qualitative variables will be presented in their absolute and relative frequencies. For the quantitative variables, the Kolgomorov-Smirnov test will be applied to define the distribution of the data and, according to these, corresponding descriptive statistics will be carried out. In addition, a bivariate analysis will be performed between the outcome variable (infection or not) versus the exposure variables with a regression-type confounding analysis (logistic - binary as applicable) to identify co-variability phenomena.

Expected results: This study seeks to improve patient safety, raise awareness in the music therapy community about the importance of proper cleaning of their work tools, and promote inter- and transdisciplinary knowledge between the fields of music therapy, critical medicine and epidemiology.
