Introduction: Peripheral intravenous cannulation is the preferred method to obtain vascular access, but not always successful on the first attempt. Evidence on the impact of the intravenous catheter itself on the success rate is lacking. Faster visualization of blood flashback into the catheter, as a result of a notched needle, is thought to increase first attempt success rate. The current study aimed to assess if inserting a notched peripheral intravenous catheter will increase first attempt cannulation success up to 90%, when compared to inserting a catheter without a notched needle. Design: In this block-randomized trial, adult patients in the intervention group got a notched peripheral intravenous catheter inserted, patients in the control group received a traditional non-notched catheter. The primary objective was the first attempt success rate of peripheral intravenous cannulation. Intravenous cannulation was performed according to practice guidelines and hospital policy. Results: About 328 patients were included in the intervention group and 330 patients in the control group. First attempt success was 85% and 79% for the intervention and control group respectively. First attempt success was remarkably higher in the intervention group regarding patients with a high risk for failed cannulation (29%), when compared to the control group (10%). Conclusion: This study was unable to reach a first attempt success of 90%, although first attempt cannulation success was higher in patients who got a notched needle inserted when compared to those who got a non-notched needle inserted, unless a patients individual risk profile for a difficult intravenous access.

Abstract Aims: To lower the threshold for applying ultrasound (US) guidance during peripheral intravenous cannulation, nurses need to be trained and gain experience in using this technique. The primary outcome was to quantify the number of procedures novices require to perform before competency in US-guided peripheral intravenous cannulation was achieved. Materials and methods: A multicenter prospective observational study, divided into two phases after a theoretical training session: a handson training session and a supervised life-case training session. The number of US-guided peripheral intravenous cannulations a participant needed to perform in the life-case setting to become competent was the outcome of interest. Cusum analysis was used to determine the learning curve of each individual participant. Results: Forty-nine practitioners participated and performed 1855 procedures. First attempt cannulation success was 73% during the first procedure, but increased to 98% on the fortieth attempt (p<0.001). The overall first attempt success rate during this study was 93%. The cusum learning curve for each practitioner showed that a mean number of 34 procedures was required to achieve competency. Time needed to perform a procedure successfully decreased when more experience was achieved by the practitioner, from 14±3 minutes on first procedure to 3±1 minutes during the fortieth procedure (p<0.001). Conclusions: Competency in US-guided peripheral intravenous cannulation can be gained after following a fixed educational curriculum, resulting in an increased first attempt cannulation success as the number of performed procedures increased.

Introduction: Throughout life, a patient with severe haemophilia is confronted with many treatment-related challenges. Insight into self-management and non-adherence could improve the quality of care for these patients. The aim of this study was to provide an overview of the current evidence on self-management and adherence to prophylaxis in haemophilia. Method: Based on series of studies and published literature, aspects of treatment were explored: learning and performing self-infusion, achieving self-management skills in adolescence, adherence issues and coping with haemophilia. Evidence-based and age-group-specific recommendations for haemophilia professionals were formulated. Results: Nearly, all severe haemophilia patients and parents were able to perform self-infusion and the quality level of infusion skills was acceptable. Learning self-infusion was generally initiated before the onset of puberty and full self-management was obtained 10 years later. Adherence was defined using a Delphi consensus procedure and was determined by skipping, dosing and timing of infusions. Adherence levels varied according to age, with highest levels in children (1–12 years) and the lowest among 25–40 years. Adherence to prophylaxis was acceptable (43%), yet 57% of the population struggled with prophylaxis. Qualitative research showed that the position of prophylaxis in life is the main driver of adherence. This position is influenced by acceptance and self-management skills. Regarding coping with haemophilia, the majority of patients used a problem-focused approach. Conclusion: Self-management and adherence to prophylaxis vary during the life span. Acceptance of the disease and self-management skills were important aspects that may require tailored professional support.
