Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Adult patients (>18 years) admitted to the emergency department whose health condition requires a blood sample to be drawn, the insertion of a peripheral intravenous cannula (PIVC), and the possibility of hospital admission will be approached to participant in the study. On gaining written informed consent participants, will be randomised into either the interventional group where blood will only be sampled from the PIVC or randomised into the control group where the blood sample will be obtained only by venepuncture. Insertion of the PIVC will follow clinical practice guidelines observed at the study site by medical and nursing staff trained in performing the procedure. The choice of cannula gauge will be at the discretion of the treating doctor or nurse. Blood samples will be obtained in the emergency department by an experienced nurse having previously received training by a phlebotomist. Should the participant be admitted to a hospital ward and require additional blood samples the allocation of method of sampling will remain the same for the duration of life of the original PIVC and sampled by a trained phlebotomist, nurse, or doctor. A sign will be placed by the participant’s bedspace to remind ward staff to collect blood samples either by venepuncture and not through the PIVC if randomised to the control group or if randomised to the interventional group through the PIVC and not by venepuncture. All other aspects in the medical management of participants will not be affected by their involvement in the study. Follow-up of the PIVC will occur on day three post emergency department presentation. It is standard practice in Western Australia that after three days (72 hours) all PIVCs are removed and re-sited if there is a continuing need for PIVC access. The original PIVC inserted in the emergency department will be evaluated by the nurse or medical staff on duty for signs of cannula failure and the peripheral intravenous catheter assessment score (PIVAS) used to assess signs of phlebitis and infection. A member of the research team will check the history of the original PIVC on day three following the participant’s emergency department presentation. If discharged from the hospital before the follow-up period, the participant’s medical records will be recalled and PIVC documentation reviewed. Data will be collected from the participant’s medical notes and from data obtained during insertion about the PIVC including site of insertion, cannula gauge size and treatments received through the device.

Comparator / control treatment
The comparator or control treatment for the study is the standard practice of blood sampling by venepuncture. In the emergency department this will be performed by a nurse trained by a phlebotomist in the sampling of blood by venepuncture. In the event study participants require hospital admission, any additional blood samples that are required over three days as an inpatient whilst the original PIVC remains in situ, will be sampled by venepuncture by a trained phlebotomist, nurse, or doctor. A sign will be placed by the participant's bedspace to remind ward staff to collect blood samples either by venepuncture and not through the PIVC if randomised to the control group or if randomised to the interventional group through the PIVC and not by venepuncture.

Efficacy
Statistical methods / analysis
Assuming a power of 80% and alpha risk of 0.05 estimation of sample size is based on previous literature with a sample size of 200 deemed sufficient to detect a difference between the two groups.

Continuous variables will be summarised using means and standard deviations, medians and interquartile ranges. A summary of categorical variables will be by frequencies and percentages. Comparisons between the control group and interventional group will be undertaken using student's t-test for normally distributed data and Mann Whitney U test for data not normally distributed.

Summary
Brief summary
The proposed research project is a study on blood sampling from venepuncture and intravenous cannulas. Venepuncture is when a needle is put into a vein for the specific purpose of drawing blood. Intravenous cannulas are little plastic tubes that are often put into veins to enable fluids or medications to be given. They can also be used for collecting blood. Sometimes when blood is collected through a cannula it can lead to its premature failure. This would mean that the cannula would be removed earlier than expected with the possibility of another being inserted. This study seeks to determine if collecting blood through an intravenous cannula does not increase the frequency of failure when blood is instead only collected by venepuncture.
