Central Venous Catheter Salvage in Home Parenteral Nutrition Catheter-Related Bloodstream Infections: Long-Term Safety and Efficacy Data.

BACKGROUND: Catheter-related bloodstream infections (CRBSIs) are a serious complication in the provision of home parenteral nutrition (HPN). Antibiotic salvage of central venous catheters (CVCs) in CRBSI is recommended; however, this is based on limited reports. We assessed the efficacy of antibiotic salvage of CRBSIs in HPN patients. MATERIALS AND METHODS: All confirmed CRBSIs occurring in patients receiving HPN in a national intestinal failure unit (IFU), between 1993 and 2011, were analyzed. A standardized protocol involving antibiotic and urokinase CVC locks and systemic antibiotics was used. RESULTS: In total, 588 patients were identified with a total of 2134 HPN years, and 297 CRBSIs occurred in 137 patients (65 single and 72 multiple CRBSIs). The overall rate of CRBSI in all patients was 0.38 per 1000 catheter days. Most (87.9%) infections were attributable to a single microorganism. In total, 72.5% (180/248) of CRBSIs were salvaged when attempted (coagulase-negative staphylococcus, 79.8% [103/129], Staphylococcus aureus, 56.7% [17/30]; polymicrobial infections, 67.7% [21/30]; and miscellaneous, 66.1% [39/59]). CVC salvage was not attempted in 49 episodes because of life-threatening sepsis (n = 18), fungal infection (n = 7), catheter problems (n = 20), and CVC tunnel infection (n = 4). Overall, the CVC was removed in 33.7% (100/297) of cases. There were 5 deaths in patients admitted to the IFU for management of the CRBSI (2 severe sepsis at presentation, 3 metastatic infection). CONCLUSIONS: This is the largest reported series of catheter salvage in CRBSIs and demonstrates successful catheter salvage in most cases when using a standardized protocol.

What information should lead to a suspicion of catheter sepsis in HPN?

BACKGROUND & AIMS: The diagnosis of catheter sepsis in patients on home parenteral nutrition can be difficult and patients often do not present with classical symptoms of pyrexia whilst feeding. This study reviews the clinical and diagnostic criteria needed to diagnose catheter sepsis. METHODS: A retrospective consecutive notes review of 2 years of patients presenting with catheter infections assessed symptoms, inflammatory markers and some liver function tests. The same data was also collected on those same patients who had successfully under gone line salvage. The two sets were compared using the Mann-Whitney U-test and predictive calculations were carried out using receiver operated characteristic curves. RESULTS: Over the two year period there were 37 episodes of CRBSI in 31 patients recorded. Successful catheter salvage was achieved in 30 episodes (in 24 patients) which is an 81% salvage rate. The most significant abnormality seen was a raised C-reactive protein, but less than a third of patients had a raised white cell count. However, there were significant changes in the bilirubin (p=0.0007) and albumin (p=0.0013) in these patients. Almost a third of patients who feel unwell do not present with a raised temperature. CONCLUSIONS: The diagnosis of CRBSI remains difficult, but it should be suspected in patients with newly abnormal CRP, albumin or bilirubin and in the non-specifically unwell patient a clinician should not be misled by a normal white cell count and apyrexia.

Illness beliefs of patients on home parenteral nutrition (HPN) and their relation to emotional distress.

BACKGROUND AND AIMS: Intestinal failure (IF) is likely to be the source of significant emotional distress for patients; however, little is known about the system of beliefs held by patients on home parenteral nutrition (HPN) that may underpin such distress. The present study aimed to: (1) examine the 'common-sense' representation of IF in patients on HPN; (2) investigate whether there were any differences in such representations with regard to primary diagnosis, clinical history or aspects of treatment; and (3) test the relative importance of psychological, disease and treatment factors in accounting for IF-specific emotional outcome (feelings of anger, upset, anxiety, low mood, and fear). METHODS: Sixty-one patients with IF on HPN completed an assessment of their beliefs about causes of their condition, consequences, symptoms experienced, personal and treatment control, chronicity and recurrence, and emotional representations (feelings of anger, upset, anxiety, low mood, and fear). Standard clinical information was also gathered from patients. RESULTS: Neither primary diagnosis, age, duration since start of HPN, number of nights on HPN, gender, presence of a stoma, or age at onset of HPN showed any significant differential effect on emotional representations. The principal predictors of emotional representations were: (1) poorer appraisals of patients' ability to exert personal control over aspects of their condition and treatment; and (2) the perception that the condition and treatment makes little sense to the patient (illness coherence). CONCLUSIONS: The current study demonstrates that the illness and their treatments per se are insufficient to account for patients' emotional distress. Rather, cognitive variables, chiefly beliefs about personal control and illness coherence account for more of the variance in emotional outcome than any other clinical or health-related variable assessed in the current study.
