Description of intervention(s) / exposure
Recommended guidelines are based of current, evidenced-based guidelines. The documentation of pain scores should be documented as part of patient assessment, and ongoing observations. The Australian (NHMRC) guidelines recommend time to analgesic of <30 minutes after presentation. Further, the 2014 best practice guidelines from the UK College of Emergency medicine call for an analgesic medication to be administered within 20 minutes of ED arrival. For those with severe pain, the effectiveness of analgesics should be re-assessed within 30 minutes of receiving the first dose (The College of Emergency Medicine Best practice guideline, Management of pain in Adults, 2014). The type of analgesics included in the educational campaign are recommended in the Australian (NHMRC) guidelines, and include:
•GTN
• Simple analgesics – paracetamol and non-steroidal anti-inflammatory medications. Note
that aspirin will not be considered to be a simple analgesic as this is used for antiplatelet
effect and not as an analgesic in chest pain management)
• Narcotic analgesics – Morphine, Fentanyl
• Other agents – Antacid, Liquid xylocaine

In the pre-intervention stage, observational data on time to first analgesic, time to
analgesia, and study outcomes will be collected. Our previous work has demonstrated that
recruiting 100 patients will take approximately 8 weeks. The post-intervention stage will
be conducted one month after completion of the RELIEF campaign. Data collection will
be identical to the pre-intervention phase. This data will be used to identify the efficacy
of the intervention; whether the time to first analgesic and time to analgesia has been
reduced after a period of intense educational and training support and visual pain sign is
implemented at the site.

The CI will be responsible for ensuring that patients enrolled in the study meet inclusion criteria. The CI and AIs will also ensure that educational resources are available and that in-service teaching sessions occur.


• The education campaign: This campaign will incorporate information on the ‘why’; that is, it will provision education around the importance of early analgesic use for patients and in the process of assessment for chest pain specifically. Information will be provided about the importance of documenting pain scores in the patient notes, as this has been shown to improve the provision of timely analgesics.
• Clinical champions on the floor. The campaign will target both nursing and medical staff. Clinical champions (study AIs) will be recruited to disseminate the message during clinical shifts and during educational in-services. These clinicians will be experienced and well-known staff members who can motivate their colleagues to change practices around the provision of analgesics.
• Recommended guidelines for the provision of analgesics will be developed and provided to all clinical staff as educational material (e.g., posters). These guidelines will include information on the ‘how’: agents that may be given by nursing staff without medical prescription, and information about the agent’s mechanism of action in chest pain.
• Patient controlled sticker system. Pain has long been considered the ‘fifth’ vital sign (American Pain Society, Principles of analgesic use in the treatment of acute pain and cancer pain, 1999) . However, unlike other vital signs such as blood pressure and heart rate, pain does not have a simple, ongoing visual representation of monitoring display that is directly visible to clinicians. The RELIEF intervention proposes a novel approach to patient reported pain via a visual, deliberate representation of pain that is directly visible to clinicians. Patients will be provided with a red sticker (15 cm diameter) to place on their chest. They will be instructed to remove this sticker if they have no pain but are encouraged to place it on whenever they experience pain. This will be a visual prompt for clinical staff to complete a pain assessment, provide appropriate pain relief, and document the patient’s pain score.

In the pre-intervention phase, observational data will be collected. This will include time to first analgesic, time to analgesia and other study outcomes to determine a baseline for standard care for patients presenting to the ED with chest pain.

We anticipate that our pre-intervention data collection, our intervention period and post-intervention data collection periods will take 2 months each to complete.

Statistical methods / analysis
In the pre-intervention stage, observational data on time to analgesia and study outcomes will be collected. Such data will be collected for 104 patients. The post-intervention stage will be conducted one month after completion of the RELIEF intervention program. Data collection will be identical to that performed in the pre-intervention phase and will again involve collecting data on 104 eligible patients. This data will be used to identify the efficacy of the intervention.
The time to and type of first analgesic will be collected from the patient medical notes. To identify time to analgesia, defined as a pain score of ‘0’, consenting participants will be sent an automated text message at 30 minutes, 60 minutes, 120 minutes and 240 minutes after presentation to the Emergency Department. This text will ask them to provide information about their current pain score (on a scale of 1 to 10). Where patients do not have a phone, a Department-owned iPad will be provided to them for this data collection. The text will state: “Please send us a message with your pain score now. Use the pain score from 0 to 10 that represents the intensity of your pain. 0 means no pain and 10 means the worst possible pain. The middle of the scale (around 5) is moderate pain. Thank you”.
Basic participant demographics, cardiac risk factors/stratification, additional analgesics given, cardiac tests received & results, hospital disposition, ED and total hospital length of stay will be collected from both the participant and relevant hospital databases (e.g. EDIS, HBCIS). Initially identifiable data will be recorded on a paper based case report form. De-identified data will be later entered into a password protected redcap database on a password protected computer in a locked research office.

De-identified data will be entered into a redcap database and exported to Stata for analysis. To identify the baseline time to first analgesic, time to analgesia and type of first analgesic (aim 1), we will provide descriptive statistics and present the data graphically. If all patients have data for time to first analgesic, standard descriptive statistics will be reported. However, there may be some patients who do not receive an analgesic at all before discharge. In this instance, median time to analgesic (with IQR) will be calculated using survival analysis.
To examine the relationship between time to first analgesic, time to analgesia, and outcomes (aim 2), regression models will be utilised. Regression models will be fit with an appropriate error distribution for the outcome of interest (binomial for ordinal data and gaussian or gamma for continuous data). If there is censoring in the time to analgesic data (ie, patients left the department before an analgesic is provided), maximum likelihood methods will be used to estimate regression parameters (30) to ensure unbiased estimates. The regression models will incorporate control variables such as risk stratification on presentation, patient age, risk factors and prior cardiac history.
To examine the impact of the RELIEF intervention (aim 3), descriptive statistics will be reported for the outcome variables before and after the intervention. Cox regression analysis will also be performed to compare time to first analgesic in the pre- and post- cohorts, controlling for any potential baseline characteristics in the two groups and for time (as outlined in the confounders section). Time to analgesia will only be collected at specific timepoints, making this variable interval censored. As such, a proportional odds model will be fitted for this variable. All other endpoints will be compared using regression analyses (logistic, gaussian or gamma as appropriate).
