Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Intervention 1: Decontamination of the needleless connector using a 2% chlorhexidine and 70% alcohol swab

Intervention 2: Decontamination of the needleless connector with the use of a 70% alcohol impregnated cap that is screwed into place on the needleless connector, and remains in place until nursing staff are required to inject medications into the connector. The cap is discarded, and a new one applied once treatment has been completed. The cap can stay in position for up to one week, and is required to be in position for at least 5 minutes prior to decontamination taking effect.

Overall duration of the intervention will be from device insertion through to device removal, or up to 4 weeks from time of recruitment (whichever comes first).
The frequency of decontamination will be each time the connector is accessed.
Ward nursing staff will be administering the intervention.
Adherence to the intervention will be monitored by a Research nurse twice weekly to assess compliance.

Outcomes
Primary outcome [1] 295502 0
The composite primary outcome of this pilot trial is to assess: feasibility (eligibility (proportion of screened patients eligible >80%), recruitment (proportion of eligible patients recruited >80%), retention and attrition (<5%), protocol adherence (>90%), missing data, staff satisfaction); data collection strategies; proposed methods; and to test the interventions with the control to determine an appropriate size for a future larger clinical trial.
Timepoint [1] 295502 0
At the completion of the research study
Secondary outcome [1] 315714 0
Central line-associated bloodstream infection: as defined by CDC/NHSN criteria.
This will be confirmed by a blinded infectious diseases specialist using de-identified clinical and microbiological data.
Timepoint [1] 315714 0
Between the time of device insertion and 48 hours after device removal, or patient removal from study, whichever comes first.
Secondary outcome [2] 315716 0
Mortality
Timepoint [2] 315716 0
Patients will be assessed for outcomes 48 hours after device removal, or patient removal from study, whichever comes first.
Secondary outcome [3] 374450 0
Primary bloodstream infection (laboratory confirmed bloodstream infection): as defined by CDC/NHSN criteria.
This will be confirmed by a blinded infectious diseases specialist using de-identified clinical and microbiological data.
Timepoint [3] 374450 0
Between the time of device insertion and 48 hours after device removal, or patient removal from study, whichever comes first.
Secondary outcome [4] 374451 0
Device (tip) colonisation: defined as a positive tip culture (equal to or more than 15 colony forming units). (Note. device tips will be removed upon suspicion of infection by the treating clinical team, not research staff).
Timepoint [4] 374451 0
Upon removal of the central line.
