Abstract
The role that fomites have to play in surgical site infection (SSI) and periprostheitic joint infection (PJI) has been observed and researched in the past. However the role that cellphones play in the transfer of microorganisms from hands to surgical sites and the indiscriminate use of cellphones within the Orthopaedics, could increase the risk of infection. This study aimed to measure the contamination of cellphones of health care workers (HCW's) in a South African tertiary hospital. Secondarily was to investigate the cellphone hygiene behaviour of HCW's.
A prospective cross-sectional study was conducted in June 2022. Samples were taken from the the participant's cellphones under an aseptic technique and sent for microbiology. The participants also filled out a questionnaire on cellphone behaviour. The inclusion criteria was orthopaedic HCW's working in the institution; This included nurses and doctors in the orthopaedic theatres and main orthopaedic wards.
Sixty-two participants were included; 54 from Orthopaedics and 7 from Anaesthesia. From the samples, 71% grew pathogens while 30,64% grew two or more colonies. This is slightly lower than other studies which showed contamination up to 100%. Micro-organisms cultured included Staphylococcus species; S.Epidermidis, Methycillin sensitive S.aureas; and E.Coli. Cellphone hygiene behaviour was also better than most other studies in terms of frequency of cleaning the devices and hand hygiene around cellphone usage. This which may be a contributing factor to the lower micro-organism contamination.
This study should be the first of many as we have identified that there are indeed pathogens on cellphones transferable to patients; causing sepsis. Though cellphones have become vital in patients management in the hospital setting, factors such as improvement in cellphone hygiene through education and frequent cleaning of cellphones will aid in disabling the negative impact of cellphones in the orthopaedic environment.
