Peripheral intravenous cannulation decision-making in emergency settings: a qualitative descriptive study

OBJECTIVES

Rates of unused ('idle') peripheral intravenous catheters (PIVCs) are high but can vary per setting. Understanding factors that influence the decision-making of doctors, nurses and paramedics in the emergency setting regarding PIVC insertion, and what factors may modify their decision is essential to identify opportunities to reduce unnecessary cannulations and improve patient-centred outcomes. This study aimed to understand factors associated with clinicians' decision-making on whether to insert or use a PIVC in the emergency care setting.

DESIGN

A qualitative descriptive study using in-depth semistructured interviews and thematic analysis.

SETTING

Gold Coast, Queensland, Australia, in a large tertiary level emergency department (ED) and local government ambulance service.

PARTICIPANTS

Participants recruited were ED clinicians (doctors, nurses) and paramedics who regularly insert PIVCs.

RESULTS

From the 15 clinicians interviewed 4 key themes: knowledge and experience, complicated and multifactorial, convenience, anticipated patient clinical course, and several subthemes emerged relating to clinician decision-making across all disciplines. The first two themes focused on decision-making to gather data and evidence, such as knowledge and experience, and decisions being complicated and multifactorial. The remaining two themes related to the actions clinicians took such as convenience and anticipated patient clinical course.

CONCLUSION

The decision to insert a PIVC is more complicated than clinicians, administrators and policy-makers may realise. When explored, clinician decisions were multifaceted with many factors influencing the decision to insert a PIVC. In actual practice, clinicians routinely insert PIVCs in most patients as a learnt reflex with little cognitive input. When considering PIVC insertion, more time needs to be devoted to the awareness of: (1) decision-making in the context of the clinician's own experience, (2) cognitive biases and (3) patient-centred factors. Such awareness will support an appropriate risk assessment which will benefit the patient, clinician and healthcare system.

Impact of educational leadership and interprofessional learning on vascular access training

Educational leadership supports the effective transfer of knowledge and clinical skills between practitioners. Evaluation of training is imperative to ensure safe and effective transfer of learning into clinical practice. This study explores and critically evaluates the impact of educational leadership on practitioner development and clinical practice, focusing specifically on paediatric vascular access. An educational intervention, consisting of theory and practical simulation of venepuncture and cannulation, followed by interprofessional mentorship and supported practice in the clinical setting, was provided to 18 foundation doctors. Data regarding knowledge and skills before and after the intervention, evaluation of expert facilitation and practitioner development was collected through a three-stage process: before and after the training, and in a short semistructured interview six weeks after the intervention. Overall, practitioners' knowledge and clinical skills were improved, which illustrates the benefits of collaborative learning. Findings also show there is a need for specialist education and training, and that educational leadership needs to be promoted in healthcare settings. There are benefits in having education delivered in collaborative partnerships and by experts and skilled practitioners. This study also highlights that vascular access training within paediatrics varies a widely.

Monitoring quality of care for peripheral intravenous catheters; feasibility and reliability of the peripheral intravenous catheters mini questionnaire (PIVC-miniQ)

BACKGROUND

Peripheral intravenous catheters (PIVCs) account for a mean of 38% of catheter associated bloodstream infections (CABSI) with Staphylococcus aureus, which are preventable if deficiencies in best practice are addressed. There exists no feasible and reliable quality surveillance tool assessing all important areas related to PIVC quality. Thus, we aimed to develop and test feasibility and reliability for an efficient quality assessment tool of overall PIVC quality.

METHODS

The Peripheral Intravenous Catheter- mini Questionnaire, PIVC-miniQ, consists of 16 items calculated as a sum score of problems regarding the insertion site, condition of dressing and equipment, documentation, and indication for use. In addition, it contains background variables like PIVC site, size and insertion environment. Two hospitals tested the PIVC-miniQ for feasibility and inter-rater agreement. Each PIVC was assessed twice, 2-5 min apart by two independent raters. We calculated the intraclass correlation coefficient (ICC) for each hospital and overall. For each of the 16 items, we calculated negative agreement, positive agreement, absolute agreement, and Scott's pi.

RESULTS

Sixty-three raters evaluated 205 PIVCs in 177 patients, each PIVC was assessed twice by independent raters, in total 410 PIVC observations. ICC between raters was 0.678 for hospital A, 0.577 for hospital B, and 0.604 for the pooled data. Mean time for the bedside assessment of each PIVC was 1.40 (SD 0.0007) minutes. The most frequent insertion site symptom was "pain and tenderness" (14.4%), whereas the most prevalent overall problem was lack of documentation of the PIVC (26.8%). Up to 50% of PIVCs were placed near joints (wrist or antecubital fossae) or were inserted under suboptimal conditions, i.e. emergency department or ambulance.

CONCLUSIONS

Our study highlights the need for PIVC quality surveillance on ward and hospital level and reports the PIVC-miniQ to be a reliable and time efficient tool suitable for frequent point-prevalence audits.
