Abstract: Background: Hospital acquired infections (HAIs) occurs frequently among hospitalized patients and Blood pressure cuffs (B.P cuffs), as with other non - invasive devices have been shown to be involved in the transmission of colonizing pathogens. No standard protocol advocating the importance of sterilisation of the B.P cuffs, which imply these devices, are not considered being a significant risk as fomites or no pathogenic risk for HAIs. Hence our study is aimed to know the bacterial colonization in the B.P cuffs using in our hospital and to emphasize the importance of high vigilance and decontamination of B.P cuffs in prevention of cross infections in hospital settings. Methods: Sample was collected from the inner surface of the B.P cuffs (n=50) before and after decontamination with 70% isopropyl alcohol by using sterile swab soaked in sterile saline. The culture was done as per standard conventional methods. Results: Among the B.P cuffs (n=50) sampled, 34/50 were showing high contamination (>300cfu/plate), 10/50 showed insignificant growth (10 cfu/plate) and 6/50 showed no growth. The organisms isolated were Methicillin Resistant Staphylococcus aureus (MRSA) 10/50, Coagulase Negative Staphylococcus (CNS) 12/50 and Klebsiella pneumoniae 12/50. After decontamination no growth of MRSA and CNS were found whereas Klebsiella pneumoniae was reduced in number 10cfu/plate in all the previously grown samples. Conclusion: Our study showed significant level of bacterial colonization in the B.P cuffs. So an urgent need to alert and educate hospital staffs which will strengthen the care for developing and implementing validated standard operating procedure for the maintenance of B.P cuffs.
