Home hemodialysis (HHD) is closely associated with the development of in-center hemodialysis (HD), being introduced gradually as the survival of dialysis patients increased with the progress of technology and scientific research. It peaked fifty years ago and then gradually declined. Nowadays there is a revival of HHD highlighting the clinical and quality of life benefits attributed to it. The practice is already solid in several countries internationally and in France the trend is growing up. However, in-center HD remains largely majority and several obstacles to the development of HHD are reported. In this article we address in particular the complex clinical context (heart failure, central venous catheter) of situations that may arise in daily practice that may call into question a HHD project. © 2022 Société francophone de néphrologie, dialyse et transplantation.

[Infections on catheters in hemodialysis: Temporal fluctuations of the infectious risk]

BACKGROUND

International guidelines recommend to limit the long-term use of central-veinous catheters in patients undergoing hemodialysis, because they expose the patient to a higher infectious risk than the fistulas. However, for some patients with comorbidity, switching to a permanent vascular access is not possible. In such case, the catheter is used for a longer period. It seems therefore important to study the influence of a prolonged duration of catheterization on infectious complications. The temporal fluctuation profile of the infectious risk is poorly studied in the literature and the results published may be contradictory.

METHODS

This multicentric prospective study included 1053 incident tunneled catheters. Multivariate logistic regression was used to identify significant risk factors of infection. An infection-free survival analysis was performed afterwards to estimate the variation of the instantaneous infectious risk during catheterization.

RESULTS

The major risks factors of infections on tunneled catheters were: previous Staphylococcus aureus infection (aOR=1.95 [1.16-3.27]; P=0.012), diabetes (aOR=1.67 [1.16-2.41]; P=0.006), and long duration of catheterization (0-3months vs.≥24months: aOR=2.42 [1.34-4.36]; P=0.003). The survival analysis showed a higher risk of infections of tunneled catheters during the first months after placement. Risk declines over time.

CONCLUSIONS

The fluctuation profile of the infectious risk show that preventive precautions should target the first months of catheterization.

[Multicenter validation study of a questionnaire assessing patient satisfaction with and acceptance of totally-implanted central venous access devices]

OBJECTIVE

Most cancer patients require a totally-implanted central venous access device (TIVAD) for their treatment. This was a prospective, multicenter, open study to: (i) develop and validate a French-language questionnaire dubbed QASICC (Questionnaire for Acceptance of and Satisfaction with Implanted Central Venous Catheter) assessing patient's satisfaction with and acceptance of their TIVAD; (ii) develop a mean score of patient's acceptance and satisfaction; (iii) look for correlation between QASICC score and TIVAD patient/tumor pathology/device characteristics.

METHODS

From 2011 November to 2012 December, the first version of the QASICC questionnaire that included 27 questions assessing seven dimensions was re-tested among 998 cancer patients in eleven French cancer hospitals (eight cancer research institutes and three university/general hospitals). The goal was: (i) to reduce the questionnaire item and dimension number (pertinency, saturation effect, item correlation); (ii) to assess its psychometric properties, demonstrate its validity and independency compared to (EORTC) QLQC30; (iii) to correlate clinical and pathological patient's/tumor's/TIVAD's parameters with the QASICC questionnaire score (the higher the overall score, the greater the acceptance and satisfaction). The questionnaire was administered to the patient 30 days (±15 days) after TIVAD's implantation.

RESULTS

Among 998 questionnaires given to cancer patients, 658 were analyzed and 464 were fully assessed as there was no missing data. Time to fill-in the questionnaire was five minutes in 90% patients. Final QASICC tool included twenty-two questions assessing four homogeneous dimensions (65%<Cronbach coefficient<85%): (i) impact on daily activities and professional activities; (ii) esthetics and privacy; (iii) pain, contribution to the comfort of the treatment; (iv) local discomfort. Respective assessment scores were 23.6%, 32.9%, 20.4% and 18.0%. Overall satisfaction score was 75.8%; global assessment score was 76.2%. These scores were significantly linked to patient's gender, anesthesia type, TIVAD's implantation side, patient's age and tumor type.

CONCLUSIONS

This second and final methodological and statistical validation of this auto-questionnaire QASICC allows us to propose it as a dedicated questionnaire to TIVAD's cancer patients by using a score assessing acceptance and satisfaction regarding their device.

A life-threatening complication of parenteral nutrition: how to prevent cardiac tamponade?

Complications caused by incorrect central venous insertion are numerous. Cardiac tamponade is a rare, but well-documented complication that is often lethal. We present the case of a patient with cardiac tamponade caused by incorrect tip position and infusion of hyperosmolar fluids such as for parenteral nutrition.
