Replacement of Failing Tunneled Hemodialysis Catheters through Pre-existing Subcutaneous Tunnels: A Comparison of Catheter Function and Infection Rates for De Novo Placements and Over-the-Wire Exchanges

PURPOSE Tunneled hemodialysis catheter dysfunction often occurs from fibrin sheath formation. As a way to preserve existing catheter venous access sites, the authors evaluated over-the-wire exchange of catheters through pre-existing subcutaneous tunnels as an alternative to catheter removal and de novo catheter replacement. PATIENTS AND METHODS One hundred nineteen catheters were placed in 68 patients. Seventy-seven catheters were placed de novo and 42 catheters were placed through the pre-existing subcutaneous tunnels of failing catheters. Technical success, short-term complications, infection rates, and functional catheter longevity were evaluated. RESULTS Technical success for catheter exchange was 93%. Infection rates were comparable to those of de novo catheter placement: 0.15 and 0.11 infections per 100 catheter days for de novo and exchanged catheters, respectively. Catheter duration of function was not significantly different for de novo versus exchanged catheters: 63% and 51% at 3 months, 51% and 37% at 6 months, and 35% and 30% at 12 months, respectively. CONCLUSIONS Over-the-wire exchange of tunneled hemodialysis catheters is safe and easily performed. It causes no increase in infectious complications and provides similar catheter longevity to de novo catheter placement. The procedure is an important option for prolonging tunneled hemodialysis catheter access sites.

Transvenous Removal of Fibrin Sheaths from Tunneled Hemodialysis Catheters

PURPOSE Long-term hemodialysis catheters are prone to significant dysfunction due to fibrin accumulation around their tips. The authors assessed the efficacy of transvenous snare removal of fibrin to prolong function of these catheters. PATIENTS AND METHODS Twenty-four procedures were performed in 20 patients with tunneled hemodialysis central venous catheters. Technical success was gauged by venography and the ability to infuse and aspirate catheters. Durable efficacy was assessed by improvement in hemodialysis. RESULTS Twenty-two of 24 procedures were performed successfully. In two cases residual material remained despite repeated stripping. Mean preprocedure hemodialysis blood-liters processed per hour increased from 15.1 to 19.1 L/h in the first dialysis session after stripping, and blood flow rates of 300 mL/min or greater were restored. By the fifth dialysis session after stripping, the blood-liters processed per hour dropped to 15.9 L/h as catheter flow rates returned to unacceptable levels. CONCLUSIONS Percutaneous fibrin removal with a loop snare provides no durable benefit in improving function of failing hemodialysis catheters.

Factors associated with falls in hospitalized adult patients

INTRODUCTION Despite efforts in hospitals to identify patients at risk for falls and to prevent these incidents, falls among hospitalized patients are not a rare event and continue to be a major health care concern, occurring in approximately 700,000-1,000,000 hospitalized patients per year. PURPOSE The purpose of this study was to examine intrinsic, extrinsic, and workforce factors that contribute to falls among hospitalized adult patients. METHODS A retrospective correlational design was used to examine 160 patients admitted to a medical-surgical unit over the year 2012. Analytical weighting was applied to the study sample to conduct bivariate and multivariate analysis. FINDINGS In multivariate analysis, the variables age, narcotic/sedative use, and overnight shift, significantly predicted the likelihood of a fall during the hospitalization. Cardiovascular disease, neuromusculoskeletal disease, evening shift, the implementation of fall prevention strategies and higher RN to unlicensed assistive personnel staffing ratios decreased the likelihood of a fall during the hospitalization. In addition, patients at high risk for falls using the Hendrich I fall scale were nearly 17% more likely to fall during the hospitalization. CONCLUSIONS Many factors influence the occurrence of a fall in hospitalized patients. Fall risk assessment and the implementation of fall prevention strategies are both effective strategies in the clinical area to identify and decrease the probability of a fall. The presence of the RN is significant in fall prevention in medical-surgical patients.

Needs, Concerns, Strategies, and Advice of Daily Home Hemodialysis Caregivers:

Improved patient outcomes have led to increased international interest in daily home hemodialysis as a kidney replacement therapy. Daily home hemodialysis often requires the assistance of a caregiver during and between treatments. Understanding the needs and concerns of caregivers of persons on daily home hemodialysis will inform the design of supportive interventions to improve caregiver retention and maintain their health and well-being. Using a descriptive qualitative design, the purpose of this study was to identify and describe the needs, concerns, strategies, and advice of family caregivers. Twenty-one caregivers were interviewed; five of these individuals were former caregivers of patients who had returned to outpatient hemodialysis. Data were collected via audio-recorded telephone interviews following a semistructured interview guide with five open-ended questions. A content analysis approach was used to code and analyze the data. Caregivers described needs, concerns, and strategies and offered advice in five predetermined major categories. Major findings included a need for respite services and a need for interventions to manage the emotional responses to caregiving. This study provides valuable information about relevant areas to consider when developing an intervention program for daily home hemodialysis caregivers.

Patient safety culture and nurse-reported adverse events in outpatient hemodialysis units.

Aims: Patient safety culture is an important quality indicator in health care facilities and has been associated with key patient outcomes in hospitals. The purpose of this analysis was to examine relationships between patient safety culture and nurse-reported adverse patient events in outpatient hemodialysis facilities. Methods: A cross-sectional correlational, mailed survey design was used. The analytic sample consisted of 422 registered nurses who worked in outpatient dialysis facilities in the United States. The Handoff and Transitions and the Overall Patient Safety Grade scales of the Agency for Healthcare Research and Quality’s (AHRQ) Hospital Patient on Safety Survey were modified and used to measure patient safety culture in outpatient dialysis facilities. Nurse-reported adverse patient events was measured as a series of questions designed to capture the frequency with which nurses report that 13 adverse events occur in the outpatient dialysis facility setting. Results: Handoff and transitions safety during patient shift change in dialysis centers was perceived negatively by a majority of nurses. On the other hand, a majority of nurses rated the overall patient safety culture in their dialysis facility as good to excellent. All relationships between patient safety culture items and adverse patient events were in the expected direction. Negative ratings of handoffs and transitions safety were independently associated with increased odds of frequent occurrences of vascular access thrombosis and patient complaints. Negative ratings of overall patient safety culture in dialysis units were independently associated with increased odds of frequent occurrences of medication errors by nurses, patient hospitalization, vascular access infection, and patient complaints. Conclusion: Findings from this analysis indicate that a positive patient safety culture is an important antecedent for optimal patient outcomes in ambulatory care settings.
