Differences in observed and self-reported compliance with the 5 moments for hand hygiene as a function of healthcare workers' empathy

BACKGROUND

Hand hygiene at critical time-points (as established by the WHO model 'Five moments for hand hygiene') remains the leading measure for minimising the risk of healthcare-associated infections. While many interventions have been tested to improve hand hygiene compliance (HHC) of healthcare workers (HCWs), little is known about the relation between HHC and HCW empathy.

AIM

The aim of this study was to investigate the relation between moment-specific HHC rates and HCWs' empathy, at both individual and ward levels.

METHODS

HHC data was collected via observation and self-report, staffs' empathy levels were measured using an established questionnaire. The survey was conducted on 38 wards of three tertiary-care hospitals in Germany. Observation data was obtained via in-house observations which were conducted up to eight months before or after the survey.

FINDINGS

Evidence for the expected correlation between HCW empathy and moment-specific HHC was found for both observed HHC (Moment 1: r = .483, p = .031; Moment 2: r = 588, p = .006) and self-reported HHC (Moment 1: r = .093, p = .092; Moment 2: r = .145, p = .008). In analyses of variance the critical interaction effect between empathy (i.e., lower vs. higher empathy) and designated time-point of hand hygiene (i.e., before vs. after reference task) was also significant.

CONCLUSION

HCWs' empathy should be considered as an important factor in explaining differences between moment-specific HHC rates. In consequence, empathy comes into focus not only as a crucial factor for high-quality patient care, but as an important contributor to improving HHC, too.

Mucosal immunization against ovine lentivirus using PEI-DNA complexes and modified vaccinia Ankara encoding the gag and/or env genes

Sheep were immunized against Visna/Maedi virus (VMV) gag and/or env genes via the nasopharynx-associated lymphoid tissue (NALT) and lung using polyethylenimine (PEI)-DNA complexes and modified vaccinia Ankara, and challenged with live virus via the lung. env immunization enhanced humoral responses prior to but not after VMV challenge. Systemic T cell proliferative and cytotoxic responses were generally low, with the responses following single gag gene immunization being significantly depressed after challenge. A transient reduction in provirus load in the blood early after challenge was observed following env immunization, whilst the gag gene either alone or in combination with env resulted in significantly elevated provirus loads in lung. However, despite this, a significant reduction in lesion score was observed in animals immunized with the single gag gene at post-mortem. Inclusion of IFN-gamma in the immunization mixture in general had no significant effects. The results thus showed that protective effects against VMV-induced lesions can be induced following respiratory immunization with the single gag gene, though this was accompanied by an increased pulmonary provirus load.
