Assessment of an umbilical venous catheter dwell-time of 8-14 days versus 1-7 days in very low birth weight infacts (UVC - You Will See): a pilot single-center, randomized controlled trial.

BACKGROUND: Umbilical venous catheters (UVCs) are used for central vascular access in preterm infants, but controversy exits with regard to the optimum dwell-time. PATIENTS AND METHODS: Prospective, randomized controlled trial at a level III University neonatal intensive care unit (NICU), comparing a UVC dwell-time of 1-7 days (control group) to 8-14 days (intervention group) in very low birth weight (VLBW) infants. PRIMARY OUTCOME PARAMETER: Number of infants requiring additional peripherally inserted central catheters (PICC) after removal of UVC. SECONDARY OUTCOME PARAMETERS: Total number of central lines (CL = UVC and PICCs) until time point of full enteral feeds (130-160 mL/kg/d), total number of intravenous vascular catheters, number of CL-associated complications (infection, thrombosis/emboli, organ injury, secondary CL dislocation), number of X-rays for assessment of CL positioning, and days of therapy (DOT) (teicoplanin) for CL-associated blood stream infections (CLABSI). RESULTS: Of 116 patients screened for eligibility, 63 patients were enrolled - control group: 31 infants, mean gestational age (GA) 280 weeks (standard deviation (SD) 2.6 weeks), mean birth weight (BW) 988.9 g (SD 322.0 g); intervention group: 32 infants, mean GA 285 weeks (SD 3.0 weeks), mean BW 1078.9 g (SD 324.6 g). In the control group, 28 infants required additional PICCs versus 16 in the intervention group (p < 0.001); total number of CLs: control group n = 58 versus intervention group n = 28; p < 0.001, and the total number of venous vascular devices was also significantly higher in the control group (109 versus 61; p = 0.04). No significant differences were seen with regard to CL-associated complications (p = 0.09). The number of X-rays for assessment of correct CL-position significantly lower in the intervention group (144 versus 96; p = 0.03). In the intervention group, length of hospital stay was significantly shorter (88.1 (SD: 35.3 days) versus 68.1 (SD: 32.6 days); p = 0.03) and GA significantly lower at discharge from the hospital (404: SD: 33 weeks) versus 385: SD: 25 weeks; p = 0.02. No differences existed with regard to neonatal morbidities and mortality at 36 weeks gestational age. CONCLUSIONS: A longer UVC dwell-time of up to 14 days significantly decreased the number of painful invasive vascular procedures and radiation exposure, and shortened the length of the hospital stay. The findings of our pilot study should be confirmed in a larger, multi-center RCT with the primary focus on catheter-associated complications.

Can a collapse of global civilization be avoided?

Environmental problems have contributed to numerous collapses of civilizations in the past. Now, for the first time, a global collapse appears likely. Overpopulation, overconsumption by the rich and poor choices of technologies are major drivers; dramatic cultural change provides the main hope of averting calamity.

Building community and public health nursing capacity: a synthesis report of the National Community Health Nursing Study.

OBJECTIVES: 1) To describe the community health nursing workforce in Canada; 2) To compare, across political jurisdictions and community health sectors, what helps and hinders community nurses to work effectively; 3) To identify organizational attributes that support one community subsector--public health nurses--to practise the full scope of their competencies. METHODS: Our study included an analysis of the Canadian Institute for Health Information nursing databases (1996-2007), a survey of over 13,000 community health nurses across Canada and 23 focus groups of public health policy-makers and front-line public health nurses. RESULTS: Over 53,000 registered and licensed practical nurses worked in community health in Canada in 2007, about 16% of the nursing workforce. Community nurses were older on average than the rest of their profession. Typical practice settings for community nurses included community health centres, home care and public health units/departments. To practise effectively, community nurses need professional confidence, good team relationships, supportive workplaces and community support. Most community nurses felt confident in their practice and relationships with other nurses and professionals, though less often with physicians. Their feelings about salary and job security were mixed, and most community nurses would like more learning opportunities, policy and practice information and chances to debrief about work. They needed their communities to do more to address social determinants of health and provide good quality resources. Public health nursing needs a combination of factors to succeed: sound government policy, supportive organizational culture and good management practices. Organizational attributes identified as supports for optimal practice include: flexibility in funding, program design and job descriptions; clear organizational vision driven by shared values and community needs; coordinated public health planning across jurisdictions; and strong leadership that openly promotes public health, values their staff's work and invests in education and training. CONCLUSION: The interchangeable and inconsistent use of titles used by community nurses and their employers makes it difficult to discern differences within this sector such as home care, public health, etc. Our studies also revealed that community nurses: thrive in workplaces where they share the vision and goals of their organization and work collaboratively in an atmosphere that supports creative, autonomous practice; work well together, but need time, flexible funding and management support to develop relationships with the community and their clients, and to build teams with other professionals; could sustain their competencies and confidence in their professional abilities with more access to continuing education, policies, evidence and debriefing sessions.
