Management of Home Parenteral Nutrition: Complications and Survival.

BACKGROUND AND AIMS: Parenteral nutrition (PN) has become an efficient, safe, and convenient treatment over years for patients suffering from intestinal failure. Home PN (HPN) enables the patients to have a high quality of life in their own environment. The therapy management however implies many restrictions and potentially severe lethal complications. Prevention and therapy of the latter are therefore of utmost importance. This study aims to assess and characterize the situation of patients with HPN focusing on prevalence of catheter-related complications and mortality. METHODS: Swiss multicentre prospective observational study collecting demographic, anthropometric, and catheter-related data by means of questionnaires every sixth month from 2017 to 2019 (24 months), focusing on survival and complications. Data were analysed using descriptive statistics. Logistic regression models were fitted to investigate association between infection and potential co-factors. RESULTS: Seventy adult patients (50% women) on HPN were included (≈5 patients/million adult inhabitants/year). The most common underlying diseases were cancer (23%), bariatric surgery (11%), and Crohn's disease (10%). The most prevalent indication was short bowel syndrome (30%). During the study period, 47% of the patients were weaned off PN; mortality rate reached 7% for a median treatment duration of 1.31 years. The rate of catheter-related infection was 0.66/1,000 catheter-days (0.28/catheter-year) while the rate of central venous thrombosis was 0.13/1,000 catheter-days (0.05/catheter-year). CONCLUSION: This prospective study gives a comprehensive overview of the adult Swiss HPN patient population. The collected data are prerequisite for evaluation, comparison, and improvement of recommendations to ensure best treatment quality and safety.

Repair of central venous access devices in intestinal failure patients is safe and cost-effective: A retrospective single centre cohort study.

INTRODUCTION: Patients with chronic intestinal failure (IF) require home parenteral nutrition (HPN). Central venous access is needed for prolonged use of PN, usually via a long term central venous access device (CVAD). Post insertion there may be mechanical complications with a CVAD such as catheter rupture or tear. Repair of damaged CVADs is possible to avoid risks associated with catheter replacement in patients with IF. However, catheter related blood stream infections (CRBSI) are a concern when CVAD's are accessed or manipulated. AIMS: To investigate the success of repair of CVADs in patients with IF on HPN, related to repair longevity and incidence of CRBSI following repair. METHOD: Nutrition team records of CVAD repairs carried out in patients with IF were reviewed retrospectively for the period April 2015 to March 2019. RESULTS: Nutrition Clinical Nurse Specialists carried out 38 repairs in 27 patients. Male n = 5, female n = 22; mean age 55 years. Catheter longevity before first repair (n = 27): median 851 days, IQR 137-1484 days. 30/38 (78.9%) of repairs were successful lasting ≥30days. Hospital admission was avoided in 76% of cases. 4 patients in the failed repair group underwent catheter re-insertion where 4 had a further, subsequently successful, repair, an overall success rate of 89.4% (34/38). 30-day CRBSI rate was 0.09/1000 catheter days in repaired catheters. In comparing costs, there is a potential cost saving of 2766GBP for repair compared to replacement of damaged CVADs. CONCLUSION: Repair of tunnelled CVADs in patients with IF is successful and safe with no increased risk of CRBSI. Significant cost savings may be made.

ESPEN guideline on home parenteral nutrition.

This guideline will inform physicians, nurses, dieticians, pharmacists, caregivers and other home parenteral nutrition (HPN) providers, as well as healthcare administrators and policy makers, about appropriate and safe HPN provision. This guideline will also inform patients requiring HPN. The guideline is based on previous published guidelines and provides an update of current evidence and expert opinion; it consists of 71 recommendations that address the indications for HPN, central venous access device (CVAD) and infusion pump, infusion line and CVAD site care, nutritional admixtures, program monitoring and management. Meta-analyses, systematic reviews and single clinical trials based on clinical questions were searched according to the PICO format. The evidence was evaluated and used to develop clinical recommendations implementing Scottish Intercollegiate Guidelines Network methodology. The guideline was commissioned and financially supported by ESPEN and members of the guideline group were selected by ESPEN.

Antimicrobial Locks in Patients Receiving Home Parenteral Nutrition.

Catheter-related bloodstream infection (CRBSI) is one of the most common and potentially fatal complications in patients receiving home parenteral nutrition (HPN). In order to prevent permanent venous access loss, catheter locking with an antimicrobial solution has received significant interest and is often a favored approach as part of the treatment of CRBSI, but mainly for its prevention. Several agents have been used for treating and preventing CRBSI, for instance antibiotics, antiseptics (ethanol, taurolidine) and, historically, anticoagulants such as heparin. Nonetheless, current guidelines do not provide clear guidance on the use of catheter locks. Therefore, this review aims to provide a better understanding of the current use of antimicrobial locking in patients on HPN as well as reviewing the available data on novel compounds. Despite the fact that our current knowledge on catheter locking is still hampered by several gaps, taurolidine and ethanol solutions seem promising for prevention and potentially, but not proven, treatment of CRBSI. Additional studies are warranted to further characterize the efficacy and safety of these agents.

Repair of Central Venous Catheters in Home Parenteral Nutrition Patients.

For patients receiving home parenteral nutrition (HPN), vascular access with a central venous catheter (CVC) is essential to safely administer parenteral nutrition (PN) to meet their nutrition and hydration needs. Unfortunately, despite rigorous training and prevention strategies, CVCs are susceptible to complications such as infection, occlusion, thrombosis, and mechanical failure. Much of the published research on CVC complications focuses on infections; however, catheter occlusions and mechanical failures also contribute significantly to catheter dysfunction and loss. Frequent CVC exchanges put HPN patients at risk of loss of vascular access, making it essential that any strategies that can salvage the CVC be implemented prior to removal. CVC repair is 1 technique that can be utilized to avoid CVC exchanges in certain situations. CVC repairs can be performed in the office or on the ward and are cost effective when compared with CVC replacement. When performed by trained clinical staff, the procedures are highly successful and associated with low risk.

Clinical outcomes of home parenteral nutrition patients using taurolidine as catheter lock: A long-term cohort study.

BACKGROUND & AIMS: Central venous access device (CVAD)-related complications, such as central-line associated bloodstream infections (CLABSIs), CVAD-related venous thromboses (CRVTs) and -occlusions frequently occur in home parenteral nutrition (HPN) patients. A preventive strategy to decrease the incidence of CLABSIs is the use of CVAD lock solutions, such as 2% taurolidine. The aim of this study was to evaluate long-term clinical outcomes of our HPN cohort while using taurolidine as lock solution. In addition, we explored risk factors associated with CVAD-related complications. METHODS: We conducted a retrospective analysis of complications (CLABSIs, CRVTs and CVAD occlusions) and adverse events in adult HPN patients while using taurolidine as lock solution. Patients with a benign underlying disease leading to intestinal failure were included between 2006 and 2017 at our tertiary referral centre for intestinal failure. Primary outcome was the effectiveness of taurolidine, as described by complication incidence rates. Secondary objectives were to assess adverse events of taurolidine, complication rates of patients who subsequently discontinued taurolidine and started using 0.9% saline alternatively, and risk factors associated with complications. RESULTS: In total, 270 HPN patients used taurolidine during 338521 catheter days. CLABSIs, CRVTs and CVAD occlusions occurred at a rate of 0.60 (CI95% 0.52-0.69), 0.28 (CI95% 0.23-0.34), and 0.12 (CI95% 0.08-0.16) events per 1000 catheter days, respectively. In 24 (9%) patients, mild to moderate adverse events resulted in discontinuation of 2% taurolidine. A subsequent switch to 0.9% saline resulted in an increased CLABSI rate (adjusted rate ratio 4.01 (95%CI 1.23-13.04), P = 0.02). Several risk factors were identified for CLABSIs (a lower age, nontunneled catheters, infusion frequency), CRVTs (site of vein insertion), and CVAD occlusions (type of CVAD). CONCLUSION: Complication rates remained low in the long-term, and use of taurolidine was generally safe. The identified risk factors may help to create new strategies to further prevent CVAD-related complications and improve HPN care in the future.

American Society for Parenteral and Enteral Nutrition Guidelines for the Selection and Care of Central Venous Access Devices for Adult Home Parenteral Nutrition Administration.

This document represents the American Society for Parenteral and Enteral Nutrition (ASPEN) clinical guidelines to describe best practices in the selection and care of central venous access devices (CVADs) for the infusion of home parenteral nutrition (HPN) admixtures in adult patients. The guidelines targeted adults >18 years of age in which the intervention or exposure had to include HPN that was administered via a CVAD. Case studies, non-English studies, or studies of CVAD no longer available in the United States were excluded. In total, 564 abstract citations, 350 from Medline and 214 from PubMed/non-MEDLINE databases, were scanned for relevance. Of the 564 citations, 13 studies addressed at least 1 of the 6 guideline-related questions, and none of the studies were prospective and randomized. The Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria were used to adjust the evidence grade based on assessment of the quality of study design and execution. Recommendations for the CVAD type, composition, or number of lumens to minimize infectious or mechanical complications are based on a limited number of studies and expert opinion of the authors, all very experienced in home infusion therapy. No studies were found that compared best solutions for routine flushing of lumens (eg, heparin versus saline) or for maintaining catheters in situ while treating CVAD mechanical or infectious complications. It is clear that studies to answer these questions are very limited, and further research is needed. These clinical guidelines were approved by the ASPEN Board of Directors.

Infectious complications in home parenteral nutrition: A long-term study with peripherally inserted central catheters, tunneled catheters, and ports.

OBJECTIVE: Home parenteral nutrition (HPN) has become a common therapy, with tunneled central venous catheters (CVCs) being the preferred route of administration. Peripherally inserted central catheters (PICCs) have been used increasingly, but whether they should be preferred over other types of CVCs is still controversial. The aim of this study was to evaluate catheter-related complications of CVC in patients receiving HPN. METHODS: All patients treated at our center for HPN from 2007 to 2017 were prospectively included. A specialized intravenous therapy team took care of these patients. Catheter-related bloodstream infections (CRBSI) were confirmed with positive, simultaneous, differential blood cultures drawn through the CVC and peripheral vein and then semiquantitative or quantitative culture of the catheter tip. RESULTS: In all, 151 patients received HPN during the 11-y study period. Of these patients, 95 were women (63%) and 55 were men (37%), with a mean age of 58 ± 13 y. Twenty-six were non-cancer patients (17%) and the remaining 125 patients had an underlying malignancy (83%). Regarding the CVC, 116 were PICCs, 18 Hickman, and 36 ports. Confirmed CRBSI per catheter-days showed 0.15 episodes per 1000 catheter-days for PICCs, 0.72 for Hickman, and 2.02 for ports. PICCs had less-confirmed CRBSIs per 1000 catheter-days than ports (φ = 0.54, P = 0.005), but no difference between PICCs and Hickman was found (φ = 0.32, P = 0.110). Confirmed episodes of CRBSI (2 versus 13%, χ2 = 6.625, P = 0.036) were more frequent with multilumen catheters. CONCLUSIONS: In our setting, single-lumen PICC and Hickman catheters showed low infectious complications.

Rate of Catheter-Related Bloodstream Infections Between Tunneled Central Venous Catheters Versus Peripherally Inserted Central Catheters in Adult Home Parenteral Nutrition: A Meta-analysis.

BACKGROUND: Tunneled central venous catheters (TCVCs) and peripherally inserted central catheters (PICC) are often used for the provision of home parenteral nutrition (HPN). There is no formal comparison being made to study the rate of catheter-related bloodstream infection (CRBSI) between TCVCs and PICC in HPN to recommend the use of 1 over the other. METHODS: An online MEDLINE, PubMed, and Scopus search was conducted. Studies reporting the rate of CRBSI in HPN patients were included. DerSimonian and Laird random effects meta-analyses were used to analyze comparative studies, whereas Begg and Pilote's random effects meta-analysis was used to pool and analyze single-arm studies. RESULTS: Seventeen studies (12 single-arm studies and 5 comparative studies) were included for analysis. Meta-analysis of comparative studies showed that PICC use was associated with a significantly lower rate of CRBSI (relative risk (RR) 0.40, 95% CI 0.19-0.83), whereas meta-analysis of single-arm studies revealed that the relative risk for CRBSI was not statistically significantly different from unity. CONCLUSION: TCVC is more commonly used in long-term HPN. Our analysis of comparative studies showed a lower rate of CRBSI in HPN patients using PICC compared with TCVC; however, analysis of single-arm studies showed that the rate of CRBSI was comparable in PICC and TCVC use. The decision to which type of catheter is most suited for HPN patients should hence be based on the duration of treatment, level of care, patients' dexterity, as well patients' underlying comorbidities that may potentially contribute to other catheter-related complications.

Central venous catheter repair is highly successful in children with intestinal failure.

PURPOSE: Damaged central venous catheters (CVCs) are commonly repaired to avoid line replacement and preserve vascular access. However, limited data suggest an increased risk for central line-associated bloodstream infections (CLABSIs) associated with the repair procedure. The purpose of this study was to describe outcomes of CVC repairs among parenteral nutrition (PN) dependent children with intestinal failure (IF). METHODS: A 2-year retrospective review was performed on children with IF on home PN > 6 months. Outcomes of interest were repair success and postrepair CLABSI incidence. Descriptive statistics included medians and frequencies. RESULTS: A total of 36 pediatric IF patients underwent 96 CVC repairs during the study period. The median CVC repair count was 1.5 repairs/patient (range, 1 to 16 repairs/patient) with >1 repair in half the patients. Ninety-four broken catheters (98%) were successfully repaired with restoration of function. Of the unsuccessful repairs (2%), the two catheters eventually required surgical removal and replacement. One repair (1%) was followed by a CLABSI with Enterococcus faecalis in an immunocompromised patient. CONCLUSION: CVC repair is a highly successful procedure with a low risk for infection. Catheter repair should be considered whenever possible as it may extend the lifetime of the catheter and decrease the risk for vascular access loss. LEVEL OF EVIDENCE: Treatment study; level IV.

To Pull or Not to Pull: Salvaging Central Line Catheters in Home Parenteral Nutrition.

PURPOSE OF REVIEW: Catheter-related blood stream infections (CRBSI) pose a significant risk to patients on home parenteral nutrition (HPN). Recurrent loss of catheters can lead to scarring and eventual loss of central access, a potentially fatal situation for patients dependent on HPN. RECENT FINDINGS: In the past, the standard of care to treat these infections required catheter removal. More recently, several studies have indicated that many CRBSI can be treated without removal of the catheter. Successful treatment without removal can be achieved by intentionally following a catheter salvage protocol. We define this as a previously defined protocol to accurately diagnose CRBSI, identify the organism(s) involved, and effectively treat not only the blood stream infection, but also sterilize the catheter. For patients on HPN with CRBSI, consider attempting line salvage if the patient is not suffering from severe sepsis, other infection related complications, or certain specific infections. Success rates vary depending on the organism causing the infection and the risks; benefits and chance of success should be considered when deciding to attempt line salvage.

Non-Antibiotic Antimicrobial Catheter Lock Solutions in Patients on Home Parenteral Nutrition.

Patients on home parenteral nutrition (HPN) are dependent on central venous access for long-term sustenance, and catheter-related bloodstream infections (CRBSIs) are a major cause of morbidity and mortality in this patient population. As such, there is much interest in finding new methods for preventing CRBSIs in patients on HPN. As it is thought that these infections are preceded by microbial colonization of the catheter, one approach is to use antimicrobial catheter lock solutions. Although antibiotic catheter lock solutions have been present for decades, their use has been mostly limited to the treatment of CRBSIs due to concern for promoting microbial resistance. Recently, however, with the advent of non-antibiotic antimicrobial catheter lock solutions, this approach is gaining popularity as a promising method to decrease rates of CRBSI in HPN patients.

Central Line in Long-term Parenteral Nutrition in Children: A European Survey.

BACKGROUND AND AIMS: The guidelines for the insertion and maintenance of the central venous catheter (CVC) in children on long-term parenteral nutrition (PN) were published 12 years ago and studies evaluating the outcomes are limited. Therefore, the aim of the present study was to perform a survey about criteria for CVC insertion and maintenance in intestinal failure/rehabilitation centers treating children on home PN. METHODS: An online cross-sectional survey based on previous European Society of Paediatric Gastroenterology, Hepatology and Nutrition PN guidelines was distributed electronically to the members of the European Society of Paediatric Gastroenterology, Hepatology and Nutrition networking group, Network for Intestinal Failure and Transplantation in Europe and tertiary pediatric gastroenterology centers in Europe. RESULTS: Overall, 55 responses from 49 centers in 18 European countries and Israel were collected. The majority of respondents were from the United Kingdom (10, 19%), followed by Germany (7, 13%) and France (6, 11%). Eleven centers (21%) cared for >30 patients, 8 (15%) centers between 20 and 30 patients, 18 (34%) centers between 10 and 20 patients, and 16 (30%) <10 patients on home PN. There was a high variability in the majority of answers to the cross-sectional survey. CONCLUSIONS: CVC insertion and maintenance in children on home PN varies largely amongst centers in Europe. These differences could be at least partially explained by the lack of updated guidelines and limited evidence. There is an urgent need for collaborative research to make recommendations about the best possible practice.

Home Parenteral Nutrition in Adult Patients With Chronic Intestinal Failure: Catheter-Related Complications Over 4 Decades at the Main Danish Tertiary Referral Center.

BACKGROUND/AIMS: Catheter-related complications (CRCs) cause mortality and morbidity in patients dependent on parenteral support at home (HPN) due to intestinal failure (IF). This study describes the incidences of CRCs in an adult IF cohort over 40 years. It illustrates the evolution and consequences of CRCs, their association to demographic characteristics, and potential risk factors in an effort to provide the rationale for preventive precautions to the relevant patients with IF at risk. METHODS: All patients with IF discharged with HPN from 1970-2010 were included. Patient and treatment characteristics were extracted from the Copenhagen IF database. The incidences were given per 1000 central venous catheter (CVC) days. RESULTS: The 1715 CRCs occurred in 70% of the 508 patients with IF (56% of the 2191 CVCs). The incidence of catheter-related bloodstream infections (CRBSIs) was 1.43. Higher age, HPN administration by community home nurses, and prior CRBSIs significantly raised the hazard for CRBSIs. In the 1970s, catheters were generally replaced following CRBSIs, whereas catheter salvage was the norm in the 2000s. The incidences of mechanical complications, tunnel infections, and catheter-related venous thromboses were 0.80, 0.25, and 0.11, respectively. The overall CRC incidence was 2.58, decreasing the first 3 decades but peaking in the last (2.84). The deaths related to CRCs were low (0.018). CONCLUSION: Even in an experienced IF center of excellence, the incidence of CRCs increased over the 4 decades. This increase could be explained by the expansion of the indication of HPN to a more elderly and frail patient population.

Epidemiology and Risk Factors for Outpatient-Acquired Catheter-Related Bloodstream Infections in Children Receiving Home Parenteral Nutrition.

BACKGROUND: Few studies have examined the epidemiology and risk factors for the development of outpatient-acquired catheter-related bloodstream infections (CRBSIs) in children receiving home parenteral nutrition. This study aimed to (1) characterize the incidence, clinical presentation, and epidemiology of CRBSIs and (2) identify risk factors for CRBSIs in children receiving home parenteral nutrition. METHODS: A longitudinal database approved by our Institutional Review Board was created to prospectively track CRBSIs in the UCLA pediatric population from January to December 2012. Eligible patients included those < 18 years old receiving home parenteral nutrition. RESULTS: Thirty of 60 patients (50%) were diagnosed with 66 CRBSIs, for an overall CRBSI rate of 3.6 per 1000 catheter days. Of the CRBSIs, 73% were due to single microorganisms and 27% were polymicrobial. There was a significant difference in median (range) time for blood cultures to turn positive depending on type of CRBSIs (p = 0.03), with polymicrobial infections detected at 13.4 (8.7-24.3) hours, gram-negative infections at 16.5 (9-30.8) hours, and gram-positive infections at 18.9 (8.4-37.1) hours. The most common presenting symptom was fever (82%), followed by gastrointestinal symptoms (42%) and chills (29%). The only significant multivariate risk factor for CRBSIs was presence of a feeding tube (2.3-fold increase in CRBSI risk, p = 0.04). DISCUSSION: Outpatient-acquired CRBSIs are common in children receiving home parenteral nutrition. CRBSIs typically present with fever, but are also associated with gastrointestinal and/or respiratory symptoms. The presence of feeding tubes may predispose children on home parenteral nutrition to developing CRBSIs.

Prevention of Subsequent Catheter-Related Bloodstream Infection Using Catheter Locks in High-Risk Patients Receiving Home Parenteral Nutrition.

INTRODUCTION: Catheter-related bloodstream infection (CRBSI) is a serious complication in patients receiving home parenteral nutrition (HPN). Antibiotic lock therapy (ALT) and ethanol lock therapy (ELT) can be used to prevent CRBSI episodes in high-risk patients. METHODS: Following institutional review board approval, all patients enrolled in the Mayo Clinic HPN program from January 1, 2006, to December 31, 2013, with catheter locking were eligible to be included. Patients without research authorization and <18 years old at the initiation of HPN were excluded. Total number of infections before and after ALT or ELT were estimated in all patients. RESULTS: A total of 63 patients were enrolled during the study period. Of 59 eligible patients, 29 (49%) were female, and 30 (51%) were male. The median duration of HPN was 3.66 (interquartile range, 0.75-8.19) years. The mean age ± SD at initiation of HPN was 49.89 ± 14.07 years. A total of 51 patients were instilled with ALT, and 8 patients were instilled with ELT during their course of HPN. A total of 313 CRBSI episodes occurred in these patients, 264 before locking and 49 after locking ( P < .001). Rate of infection per 1000 catheter days was 10.97 ± 25.92 before locking and 1.09 ± 2.53 after locking ( P < .001). DISCUSSION: The major findings of the present study reveal that ALT or ELT can reduce the overall rate of infections per 1000 catheter days. ALT or ELT can be used in appropriate clinical setting for patients receiving HPN.

Damage of Central Catheters in Home Parenteral Nutrition Patients.

UNLABELLED: According to the ESPEN and ASPEN guidelines, in the case of a long-term (>3-month) parenteral nutrition should be administered via a subcutaneous central venous catheter (CVC). There are three types of mechanical complications of tunnelled central catheter: catheter rupture, occlusion by TPN depositing and thrombofibrotic occlusion. The aim of the study was to analyse the incidence of complications central catheter in a group of patients receiving HPN. MATERIAL AND METHODS: Between January 2010 and June 2014, HPN was conducted in 584 patients (306 women and 278 men), ninety-nine patients were enrolled in the study: 67 women and 32 men in whom mechanical complications of central catheters were found. RESULTS: Among 99 patients, 71 used the tunnelled Broviac catheter. Groshong catheters were placed only in patients receiving parenteral nutrition due to cancer. Analyses have shown differences between the older and younger in the number of mechanical complications. Younger patients were found to have a larger number of catheter complications (1.6 ± 1.1) in comparison with older patients (1.3 ± 0.7). The catheter that was most commonly damaged was the Broviac catheter 76.8%. The most frequent type of mechanical complications was catheter rupture 64.81%. CONCLUSIONS: Mechanical complications of tunnelled central catheters in HPN patients can be repaired in an outpatient setting in half of the cases, which enables continuation of parenteral nutrition without the need to hospitalise the patient. The centres that conduct HPN should offer 24-hour care and help in case of problems with the central venous line to the patients.

A comparative study of peripherally-inserted and Broviac catheter complications in home parenteral nutrition patients.

BACKGROUND & AIMS: Peripherally inserted central venous catheters (PICC) have become increasingly popular for medium to long-term parenteral nutrition (PN) but there is limited data on the complication rates in this sub-group. We aimed to compare the rates of complications associated with tunneled catheters (Broviac) and PICC in home PN (HPN) patients. METHODS: All adult patients in an HPN program with a new Broviac or new PICC between 2009 and 2011 were included in this prospective observational study. Complication rates were compared by using Poisson regression and Kaplan Meier survival curves were used to compare the first complications that occurred. RESULTS: 204 catheters (133 Broviac and 71 PICC) were inserted in 196 adult patients. Mean follow-up from catheter insertions to their removal was 276 ± 219 days for Broviac (n = 86) vs. 74 ± 140.70 days for PICC (n = 56); p < 0.001. Complications were similar between Broviac and PICC (91/133 vs. 26/71). Catheter infection rate was lower in PICC (1.87 vs. 1.05 per 1000 catheter-days; p = 0.01). Catheter obstruction rates were similar for both catheters. Only PICC experienced venous thrombosis (0.4/1000). The proportion of catheters removed was lower in the Broviac group than in the PICC group (62.4% vs. 78.8%; p = 0.01) but those removed for complications were not different (28.6.7%vs. 25.3%; p = 0.64). CONCLUSIONS: In HPN patients, overall complications were similar in both the PICC and the Broviac groups. However, the Broviac catheter could be associated with an increase in catheter infection.

Quality of life analysis during transition from stationary to portable infusion pump in home parenteral nutrition patients: a Canadian experience.

BACKGROUND: Quality of life (QOL) of patients receiving home parenteral nutrition (HPN) may be impacted by device technology. Historically, our HPN patients used pole-mounted pumps which can hinder activities and affect QOL. METHODS: Patients receiving HPN with a pole-mounted pump completed Short Form 36 (SF-36®) and pump-specific questionnaires. Patients were then enrolled in a 2-month prospective crossover open study. Patients were randomized to use a pole-mounted pump or a portable pump. After 1 month, each arm crossed over. Measurements were repeated at 4 and 8 weeks. RESULTS: Participants included 5 males, 15 females; age 52.8 ± 3.3 (mean ± SEM) years; 50% had short bowel syndrome; received HPN for 83.3 ± 15.9 months; infused HPN over 11.2 ± 0.3 hours/day; 4.3 ± 0.4 days/week. Portable pump users scored 53.75 ± 5.64, 61.25 ± 6.14, and 40.31 ± 4.94 in SF-36v2 physical, social, and health vitality, respectively, while the stationary pump users scored 45.50 ± 4.82, 55.00 ± 5.97, and 35.31 ± 4.63, respectively (NS). They reported ease of movement between rooms (4.11 ± 0.21 vs 1.44 ± 0.20; P = .001); when traveling (5.00 ± 0.00 vs 3.00 ± 0.45; P < .02) (1 = very difficult, 5 = very easy); 5.0% were sleep disturbed with the portable compared to 42.1% with pole-mounted pump (P < .04). Overall, patients were significantly happier with the portable vs pole-mounted pump (4.53 ± 0.19 vs 2.68 ± 0.22; P < .001) (1 = very unhappy, 5 = very happy). CONCLUSION: Our HPN patients reported improved happiness and satisfaction regarding ease of use and function with a portable vs pole-mounted pump.

Efficacy of taurolidine on the prevention of catheter-related bloodstream infections in patients on home parenteral nutrition.

PURPOSE: To assess the efficacy of taurolidine (TauroLockTM) line locks on the prevention of catheter-related bloodstream infections (CRBSI) in patients on home parenteral nutrition (HPN). METHODS: In our unit, any patient with ≥2 CRBSIs in six months is considered for TauroLockTM (2% taurolidine and 4% citrate) line locks. All such patients from May 2007 until January 2012 were identified, along with associated CRBSI rates. CRBSI was defined by differential time to positivity for positive blood cultures. CRBSIs were grouped into pre-taurolidine use and post-taurolidine commencement for each patient and the infection rate per 1000 catheter days calculated. Results were analyzed using Wilcoxon two-sided test. RESULTS: A total of nine patients were included (two men and seven women) with a median age of 51 (range 43-82) years. Infection rates after commencing taurolidine decreased markedly in all patients studied. The median CRBSI rate prior to taurolidine use was 6.39 per 1000 catheter days. This decreased to a median CRBSI rate of 0 per 1000 catheter days after commencing taurolidine. CONCLUSIONS: Taurolidine is no substitute for careful aseptic technique. However, it is clearly effective at preventing CRBSIs and should be used in patients with recurrent infections to reduce morbidity.
