Description of intervention(s) / exposure
The study proposes to determine the factors surrounding peripheral intravenous cannula (PIVC) insertion to identify best practices to promote first-time insertion success, and reduce repeat PIVC insertion for patients admitted to the hospital wards.
A prospective observational study of clinicians performing PIVC insertion in a patient population presenting to ED, with follow-up of any subsequent admissions to hospital wards. Observations include the insertion of PIVC in ED. Patients who are admitted with the observed ED PIVC will be followed up and observed daily until the ED PIVC is removed. All observations and questions we propose are underpinned by scientific literature and have undergone face and content validity indexing.

Outcomes
Primary outcome [1] 294986 0
First-time insertion success is the primary outcome and will be recorded as a dichotomous variable, either yes or no. PIVC insertion failure is the outcome of interest for analysis along with associated risk factors, which will be identified using regression techniques.
Timepoint [1] 294986 0
At the point of a PIVC insertion attempt in ED. The time when the ED PIVC is removed in admitted patients. The rationale for removal will be recorded.
Primary outcome [2] 294988 0
Predictors of survival time of an ED inserted PIVC

Eligibility
Key inclusion criteria
All clinical staff who place PIVCs as part of their role in the Emergency Department, and who consent to participate.
All patients >18 years will be approached. We will attempt to observe all patient types and as such a waiver of consent has been granted. However, patients with the capacity to understand what the researchers are doing will be verbally informed as to what we intend to observe. Family members present with patients who do not have the capacity to understand will also be informed. If either the patient or family members advocating on behalf of a patient decline to have a PIVC procedure observed, they will not be coerced into taking part.
Minimum age
18 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?
No
Key exclusion criteria
Patients under 18 years of age. Clinician participants who decline to provide consent. Patients with the capacity to understand and decline to take part and/or family advocating for patients who decline on the patient's behalf.

Statistical methods / analysis
Our pilot study resulted in a successful first attempt rate of
approximately 86%. Using the guidelines suggested in Peduzzi et al [1], with a sample size of 1000, we would have sufficient numbers to allow us to adequately investigate using multivariate logistic regression approximately 10 variables.
Univariate and multivariate/able logistic regression will be used to determine those variables that are predictors of first time insertion success. Univariate analysis will be conducted initially and factors that are significant at the 0.1 level entered into a multiple regression model. A significance level of 5% will be used to determine statistically significant predictors. Odds ratios and 95% confidence intervals will be provided for a final model. Diagnostic measures will be calculated and receiver operating characteristic (ROC) curves constructed, with the area under the curve (AUROC) calculated to quantify the overall prognostic discrimination for first-time insertion success. Analyses for secondary aims will include Cox proportional hazards models and will include; Time zero (T0):IV insertion, Time of event (T1): PIVC failure, Time censored (T2): PIVC removal or transfer to other hospital. Kaplan-Meier survival curves will identify the survival time of ED inserted PIVC.
