Parenteral nutrition (PN) is a life-sustaining therapy required in patients who do not have a functioning gastrointestinal tract. This can be either second to surgical removal, or malfunction (such as in malabsorptive conditions and dysmotility). The intravenous provision of nutrition requires central venous access where a hyperosmolar nutrient solution can be infused. A variety of central venous catheters (CVCs) can be used, including peripherally inserted central catheters (PICC), tunneled catheters and implanted ports. The most common complication, and most frequent cause of hospitalization in patients on home PN is bloodstream infection.
There are several new devices or solutions that are being developed to be used as primary prophylaxis for CRBSI. These include catheters with antibacterial and/or anti-biofilm properties and different catheter lock solutions. Antibiotic lock solutions have been used for salvage of central venous catheters in confirmed CRBSI. However, it is not recommended as a primary prophylaxis due to the creation of resistant organisms. According to the United States Center for Disease Control (CDC), antibiotics 'should be used only to manage infection.' However, one antimicrobial solution, taurolidine, has not been found to promote the emergence of resistant bacterial strains and it has been used successfully as a lock solution to prevent CRBSI. Although an antibiotic may have anti-biofilm properties in high concentrations but it does not have anticoagulant properties. Ethanol lock solutions (varying concentrations, but usually 70%) have also been used successfully to reduce CRBSI, however, there have been adverse events when they are used in polyurethane lines and it does not inherently have anticoagulant properties. Historically, citrate lock solution has also been used to maintain catheter patency, but in a meta-analysis, there was no difference between heparin and citrate lock with regards to catheter thrombosis or catheter related bloodstream infection.
Although its use has been evaluated in hemodialysis catheters, there are no known studies examining the use of a tetra-sodium EDTA catheter lock solution in central venous catheters of patients on home PN. Although both hemodialysis and home PN require central venous catheters, there are many differences inherent to the different usages. First, the types of catheters that are used can differ. There is more variety in the types of catheters used for home PN. Second, most patients undergo hemodialysis on a fixed schedule, three times per week for 4 to 8 hours each time, and, for the majority of patients, this is done in-center, with the assistance of a nurse. On the other hand, home PN is usually administered five or more days per week, at home, over 12 or more hours. It can be either administered with the assistance of a home care nurse or by the patient and/or their family/partner. Furthermore, the substance infused through the catheter is different. Specifically, amino acids and fat emulsions are usually only infused in home PN, although electrolytes and fluids can be infused in both.

Tetrasodium EDTA cathether lock solution
There is only one arm in this study where home parenteral nutrition patients who meet the inclusion criteria will receive tetrasodium EDTA catheter lock solution.
Device: Tetrasodium EDTA catheter lock solution
Home parenteral nutrition patients who meets inclusion criteria is to receive tetrasodium edta catheter lock solution. Patient will receive standard catheter lock solution of heparin/saline for 1 month, followed by tetrasodium EDTA catheter lock solution using withdrawal method for 1 month and followed by tetrasodium EDTA catheter lock solution using flush method for 1 month. In total, patient will stay in the study for 3 months. A phone call will be conducted before the start of the study to give instruction to patient regarding the use of catheter lock solution. Time taken to connect and disconnect TPN will be recorded by patients, twice a month on first and last mondays of the month for 3 months. A survey regarding the ease of use of catheter lock solution will be conducted at the end of each month via phone by nurse coodinator.
- Ease of use [ Time Frame: 24 months ]Acceptability of the new catheter lock solution by administering a questionnaire survey that will be conducted by the end of the usage. The questionnares will require the participant to rate the overall satisfaction of the product as '1. unsatisfied or 2. neutral or 3. satistified' and to rate the amount of time it takes to prepare the product as '1. took long or 2. neutral or 3. doesn't take too long and 3rd question compared to usual product (heparin), how easy is this product as '1. harder than heparin or 2. the same or 3. easier than heparin' and last question is ask if participant would continue to use this lock solution 'Yes' or 'No' and why not?
- Time taken to use the catheter lock [ Time Frame: 24 months ]To evaluate time required to use the catheter lock solution by recording time taken to connect and disconnect TPN on the first and last Monday of every month.
- Cost analysis [ Time Frame: 24 months ]Cost analysis of using tetrasodium EDTA catheter lock solution versus heparin saline catheter lock solution
