Values are central to ethical and effective nursing and health care. However, in relation to heart failure, an extremely common and burdensome syndrome, the role that patients' values have in influencing self-care is poorly understood. ⋯ Values are integral to how patients approach and undertake HF self-care. These values both affect and respond to this self-care and the severity of HF symptoms. Values extend to those relating to the self and others and incorporate a range of personal, life, and social dimensions. Values cannot be assumed to be fixed, normative or similar to those held by nurses and other health professionals. Future interventions to improve HF self-care must address and respond to the complexity of patients' values and how they influence patient behavior in undertaking heart failure self-care.

Review Meta Analysis
Skin antiseptics in venous puncture site disinfection for preventing blood culture contamination: A Bayesian network meta-analysis of randomized controlled trials.
To compare the efficacy of several antiseptics in decreasing the blood culture contamination rate. ⋯ Different antiseptics may not affect the blood culture contamination rate. Different intervals between the skin disinfection and the venous puncture, the different settings (emergency room, medical wards, and intensive care units) and the performance of the phlebotomy may affect the blood culture contamination rate.

Around the world, guidelines and clinical practice for the prevention of complications associated with central venous catheters (CVC) vary greatly. To prevent occlusion, most institutions recommend the use of heparin when the CVC is not in use. However, there is debate regarding the need for heparin and evidence to suggest normal saline may be as effective. The use of heparin is not without risk, may be unnecessary and is also associated with increased costs. ⋯ It remains unclear whether heparin is necessary for CVC maintenance. More well-designed studies are required to understand this relatively simple, but clinically important question. Ultimately, if this evidence were available, the development of evidenced-based clinical practice guidelines and consistency of practice would be facilitated.

Review
Dressing and securement for central venous access devices (CVADs): A Cochrane systematic review.
To compare the available dressing and securement devices for central venous access devices (CVADs). ⋯ Medication-impregnated dressing products reduce the incidence of CVAD-related bloodstream infection relative to all other dressing types. There is some evidence that chlorhexidine gluconate-impregnated dressings, relative to standard polyurethane dressings, reduce CVAD-related bloodstream infection for the outcomes of frequency of infection per 1000 patient days, risk of catheter tip colonisation and possibly risk of CVAD-related bloodstream infection. Most studies were conducted in intensive care unit settings. More, high quality research is needed regarding the relative effects of dressing and securement products for CVADs.

Nurses' 'worry' is used as a calling criterion in many Rapid Response Systems, however it is valued inconsistently. Furthermore, barriers to call the Rapid Response Team can cause delay in escalating care. The literature identifies nine indicators which trigger nurses to worry about a patient's condition. ⋯ In this single-center study we showed that adding the Early Warning Score based on vital signs to the DENWIS-indicators improves prediction of unplanned Intensive-Care/High-Dependency-Unit admission or unexpected mortality.
