Description of intervention(s) / exposure

Early identification and management of patients with difficult intravenous access (DIVA) is complex and dependent on patient, illness or injury, and provider characteristics. Prospective identification of patients with DIVA using vessel assessment instruments, combined with the use of high-quality clinical guidelines or escalation pathways (to more skilled inserters) is recommended in order to maximise first-time insertion success and to prevent peripheral intravenous catheter (PIVC) insertion failure. Our preliminary work demonstrates a strong need for a DIVA identification process which accurately highlights those patients who have DIVA; and links to an insertion escalation pathway, incorporating the use of ultrasound (US) if needed, so that DIVA patients have a better chance of having a PIVC successfully inserted on the first attempt. The current study aims to evaluate the clinical and cost-effectiveness of DIVA identification and escalation pathways. Co-production of a DIVA identification tool (e.g., screening for DIVA risk factors) and escalation pathways (e.g., escalation based on DIVA classification and inserter skill) with an Advisory group, will be undertaken by the research team at each site. Implementation strategies will be underpinned by the Behaviour Change Wheel intervention functions and policy categories and be evidence informed. Core components which the pathways must contain include:

DIVA identification pathway
- Able to be used across all disciplines/clinical areas where PIVCs are inserted
- Applicable to all patients
- History of DIVA should be assessed – Patient-reported, and medical records
- Prompt user to consider whether there is a clear indication for vascular access/PIVC insertion (refer user to ACSQHC PIVC Standards: Device Appropriateness)
- Vein visibility and palpability assessment as minimum requirements for DIVA assessment
- Lack of vein palpability and visibility should automatically classify a patient as DIVA, overriding other criteria
- Inserter skill and confidence should be assessed:
- Should not be prescriptive – allow integration of clinical judgement in decision-making process

Escalation pathway
- Timely response: Escalation to occur in reasonable timeframe
- Pathway must be applicable at all hours across all days of the week
- Distinct escalation pathways for inserters of different skill levels, and for non-DIVA and DIVA patients
- Sites should strive to construct an ideal escalation pathway, that may not be achievable initially, but can be a goal to reach towards
- Pathway must consider the urgency of PIVC insertion, and not be applicable for Resus/Code Blue situations

Implementation strategies
- Implementation strategies should:
o Be multimodal (i.e. same content delivered via different platforms/ media)
o Leverage off existing staff and workflows at each site for promoting best practice PIVC insertion, care and removal (not solely rely on research staff and investigators)
o Consider evidence-based strategies from previous vascular access or other clinical implementation projects (e.g. bundles in published papers)
- Intensity of implementation strategies should be flexible and adjusted throughout the project as necessary
- Education must include content to improve awareness of device appropriateness and vascular access requirement
- DIVA information resource should be provided to patients to facilitate patient empowerment (i.e. to request US insertions if history of DIVA is known)
- Sites will ensure appropriate infection prevention measures are in place for ultrasound equipment:
o Consider use of “DIVA Pack” containing sterile probe covers, disinfectant wipes, sterile gel, etc.
o Consider providing laminated card outlining cleaning procedures for US
- Site investigators will garner support for pathway within hospital (including executives and clinical staff)
- Change champions should understand the escalation pathway and DIVA tool well to guide others in its use
- Advisory group to consider the cohort/s of inserters to escalate to given the number of projected DIVA patients and advanced inserter availability at different times/days
- Method should be developed by advisory groups to ensure that ultrasounds are accessible/locatable when needed.
- Formal implementation plan should be developed by site advisory groups addressing each component of an implementation plan template developed by Core Group
o Advisory groups must identify or create workforce for escalation.
o Site-specific advisory groups must consider methods of changing clinician viewpoints on ultrasound-guided PIVC insertion, and normalising it as a part of standard practice

The intervention will involve (delivered via stepped wedge cluster RCT [with inbuilt process evaluation]) the implementation and evaluation of the DIVA identification and escalation pathways’ effect on clinical and implementation outcomes from four clusters at the Queensland Children’s Hospital (QCH), Royal Brisbane and Women’s Hospital (RBWH), and Gold Coast University Hospital (GCUH). All 12 hospital clusters (wards/departments) will start the trial in the control phase for two months, with baseline measures taken. Following this, one cluster per hospital will randomly (computer generated) step-up to implementation every two months over an 8-month period, until all are fully implemented. The exposure to the intervention will differ per cluster (depending on randomisation) but be between 6 and 12 months. At each time point, a random sample of a minimum 20 PIVC insertion procedures will be studied per cluster. This will be achieved by randomly selecting dates for data collection, rostering research nurses on those dates and collecting a minimum of 20 PIVC insertions that occur sequentially while the research nurse is available.

An internal process evaluation will be undertaken guided by the Consolidated Framework for Implementation Research to i) establish the extent to which the intervention is implemented as intended (implementation fidelity), over time and across different sites; ii) to ascertain how staff understand and respond to the intervention, over time and across different sites; and iii) to explore the context over time and across different sites and determine factors (including managerial, economic, organisational and work level) that affect implementation. Up to 5 staff per cluster will be interviewed (in-person or via telephone) by a member of the research team. Purposive sampling will be used to select staff involved in implementation or intervention delivery.

Intervention fidelity will be promoted by the Project Manager who will develop a study manual, train ReNs (Research Nurses), monitor allocation integrity and data quality, and work with investigators/ReNs to address any issues. Education and training to implement the intervention willl reflect literature, pilot educational programs developed by the partners, sound educational principles, and standards, (e.g., the Australasian Society for Ultrasound in Medicine requires >/=2 hours of teaching (>1 hour practical), a post-test, two supervised (marked, interactive) formative assessments and a third summative assessment) and will be delivered in-person, where feasible, by the ReNs or another member of the research team (e.g., Project Manager). Implementation education will provide evidence-based advice, but individual clinicians will make decisions (e.g. insertion site) based on patient needs.

Early detection / Screening

Comparator / control treatment

In the control steps, clusters will continue usual care. This will vary by site, however, in general usual care will be landmark insertion by default; with no/minimally implemented pathway to assess level of difficulty; and ad hoc referral to ultrasound skilled practitioners, typically after failed landmark attempts.

Study design

Statistical methods / analysis

Sample size
The study has been designed to have adequate statistical power to test the primary hypothesis. We expect that approximately 40% of recruited patients will be DIVAs (8 per cluster sample) and 60% non-DIVA (12 per cluster sample). Using Hemming’s method for cluster RCTs, including correction for intra class correlation (rho=0.03 constant throughout study), a two-sample test of proportions with 4 steps, 3 clusters randomised at each step, and 20 patients/cluster. For patients classified as DIVA, we assume the current percentage of first attempt insertion success is 50% (based on prior meta-analysis12 and consistent with our pilot50), and that there will be a 50% relative improvement to 75% of first attempt insertion success. With 20 patients recruited per cluster we will have >90% power to detect a statistically significant difference in first attempt insertion success before and after exposure to the intervention for DIVA patients (alpha=0.05).

When considering the effect of the intervention on all recruited patients, we assume the current first insertion success percentage in non-DIVA patients is 70%, and that this will rise to 80% post-intervention. This is equivalent to an overall change from 62% first attempt insertion success to 78% first attempt insertion success. With 240 patients at each of the 5 data collection periods (baseline plus 4 steps), we have >90% power to detect a statistically significant difference between pre- and post-implementation of pathways (alpha=0.05).
To measure sustainability of the primary endpoint we will continue to assess 240 patients at each sustainability time point (3 and 6 months). We will have data on 168 DIVA patients receiving the pathway at steps 3 and 4, and 192 DIVA patients at the 3- and 6-month follow-up periods combined. This will allow the identification of a drop in first attempt insertion success from 75% to <60% post-intervention with 80% power (alpha=0.05).12,50 When considering all patients regardless of DIVA status we have 420 at steps 3 and 4 and 480 at follow-up, giving 80% power to identify an overall drop in first attempt insertion success from 78% to <70% post-intervention (alpha=0.05). This leads to a total sample size of 1680 observations, consisting of 240 observations at each of the 7 periods (baseline, steps 1-4, 3- and 6-month follow-up).

Statistical analysis
Descriptive statistics will be characterised as mean (standard deviation) or median (25th-75th percentile) as appropriate, and categorical data will be characterised as frequency (percentage). The primary outcome, first insertion success in DIVA patients, will be analysed using a multi-level mixed-effects logistic regression model, with pathway (DIVA/escalation) and time period (baseline/step 1-4) included as fixed effects, with a pathway-by-period interaction term. Clinical unit (cluster) and hospital will be included as random effects, with clinical unit nested within hospital. The effect estimate will be presented as an odds ratio (OR) with 95% confidence intervals (95%CI). Secondary outcomes with binary data will be analysed using mixed-effects logistic regression models. Secondary outcomes with interval data will be assessed using mixed-effects linear regression models, with effect estimates presented as mean difference and 95%CI. Secondary outcomes with continuous, but non-interval, data will be assessed using mixed-effects median regression models, with effect estimate presented as median difference and 95%CI. Secondary outcomes with count data will be assessed using mixed-effects Poisson regression models, with effect estimates presented as incidence rate ratios and 95%CI. Secondary outcomes with time-to-event outcomes will be assessed using Cox Proportional regression models, with effect estimates presented as hazard ratios and 95%CIs. For time-to-event outcomes life tables will be constructed when appropriate. The primary analysis will be ‘intention-to-treat’, with ‘per protocol’ (PP) analyses assessing the effect of protocol compliance.

Cost-effectiveness analysis
The primary cost-effectiveness analysis will be conducted from a health system perspective. The primary outcome will be the incremental cost per incremental gain in first time insertion success. Results will be presented as incremental cost-effectiveness ratios (ICERs) with 95% credible intervals. Seemingly Unrelated Regression (SUR) will be used to estimate the ICER and characterise uncertainty as it is robust for non-normal data distributions, allows for correlation between costs/effects, will allow for control of any baseline/confounding variables and has been previously used in economic evaluation alongside stepped-wedge clinical trials51. Per patient costs will be estimated using a micro-costing or bottom-up approach, with initial measures in natural unit resource use. Next, each resource will be valued using unit prices (purchasing agreements or estimates from shadow prices). Costs associated with implementation with be annualised over assumed life expectancy of practice change (seven years) and attributed to each patient based total target patient population estimates. Data will be collected for all patients during the pre-implementation, post-implementation and sustainability phase. ICER will be estimated based on the incremental costs and effect between patients of the pre-implementation phase compared to the post-implementation or sustainability phase separately. Ultrasound will be cost-effective if the ICER less than or equal to the a priori cost effectiveness threshold for the value of first-time insertion sourced from the literature. A scatter graph of costs and effect will be used to characterise uncertainty in the ICER based on the results of the SUR. To explore the uncertainty in cost effectiveness threshold, cost effectiveness acceptability curves will assess the probability that ultrasound guided insertion is cost-effective over a range of cost effectiveness threshold values.

Process evaluation
An internal process evaluation will be undertaken guided by the Consolidated Framework for Implementation Research. The aims and objectives of the process evaluation (PE) are i) to establish the extent to which the intervention is implemented as intended (implementation fidelity), over time and across different sites; ii) to ascertain how staff understand and respond to the intervention, over time and across different sites; and iii) to explore the context over time and across different sites and determine factors (including managerial, economic, organisational and work level) that affect implementation.

Data collection methods for the PE will be:
- Initial site visits to obtain information on context and usual practice collected through interviews with staff involved in the implementation and delivery of the intervention, using purposive sampling to obtain a range of participants;
- In person and/or telephone interviews with research staff and local champions in the intervention phase to obtain information regarding the implementation process, acceptability of the intervention, barriers and clinical decisions affecting the use of the intervention.
- Final site visits to undertake interviews with a purposive sample of staff involved in implementation or intervention delivery to ascertain guideline acceptability, how workflows supported (or did not support) the pathways’ implementation, what was helpful or challenging when operationalising the pathways and whether they were useful in practice.

Interviews will be recorded and professionally transcribed. Data from the PE will be analysed –using interpretive inductive thematic analysis to gain a greater understanding of clinical phenomena that yield practical applications.

Summary

Brief summary

Our preliminary work demonstrates a strong need for a DIVA identification process which accurately highlights those patients who have DIVA; and links to an insertion escalation pathway, incorporating the use of ultrasound if needed, so that DIVA patients have a better chance of having a PIVC successfully inserted on the first attempt. The three-phased project will develop, implement and evaluate the clinical and cost-effectiveness of DIVA identification and escalation pathways. 

The Difficult Access Requires Thought, Training and Technology (DART3) project aims: 
(1) To understand and describe the budget and funding mechanisms for PIVC insertion procedures in Australian hospitals;
(2) To develop and pilot test sustainable DIVA identification and escalation pathways and associated implementation strategies suitable for the Australian care context; and,
(3) To test the effect of the DIVA identification and escalation pathways on clinical, cost and implementation outcomes
