Abstract:Purpose: The aim of this research study is to improve the overall level of performance of HM services in the control of HAIs in the NHS. Hence, the identification of the critical success factors (CSFs) and key performance measures in the control of maintenanceassociated HAIs. Design/methodology/approach: The CSFs and performance measures in HM in IC were initially identified through the application of grounded theory analysis. In round one of the Delphi exercise, the complete lists of CSFs and performance measures were presented to the Delphi participants for refinement and modification. The results of the Delphi round one exercise were analysed manually and used to refine the rounds two and three Delphi instruments. In subsequent Delphi rounds, the results were recorded using statistical software called Statistical Package for Social Sciences Statistics (SPSS) version 21, and analysed through descriptive statistics. Finding: In total, eight CSFs and fifty-three key performance measures are identified for reducing the burden of maintenance-associated HAIs in hospitals. For example, establishing clear lines of communication between the ICT (infection control team) and HM unit is important in the prevention of maintenance-associated HAIs in hospitals. Dust prevention is also identified by the healthcare experts as an important measure to prevent the transmission of maintenance-associated HAIs in high-risk patient areas. Originality/value: The findings of this research project provide healthcare authorities a list of CSFs and key performance measures for measuring performance in HM in IC. In doing so, the HM unit will be able demonstrate it contribution to the UK's government overall strategy for reducing the prevalence of HAIs in NHS hospitals.
