Pain, Acute
Conditions
Brief summary
Can a novel electronic display of pain be successfully used in the emergency department and does it (1) change analgesic prescription and (2) change amount of pain experienced? Pain is a common symptom in emergency care. As patients are seldom reassessed, staff may not be aware of pain. Currently, members of nursing or medical staff need to ask patients about their pain and record it manually using a visual analogue scale from 0-10. The new electronic display uses buttons to represent a pain scale from 0 (no pain) to 10 (worst pain). Patients will select the number that best corresponds to their pain every 15 minutes. In the experimental group, the score will be displayed on a screen. In the control group, the score will not be displayed. The investigators will compare the overall amount of pain in both groups, and will look at their pain management (painkillers prescribed). The investigators will also ask patients and staff for their opinions on the display. The study will include adult patients in the emergency department at Leicester Royal Infirmary with an initial pain score of 5 or more who are able to make a decision about whether to participate. Participants will also need to be likely to stay in the hospital for more than 2 hours to allow the investigators to gather enough useful data. The study will recruit 200 participants. If the study can demonstrate that the monitor is acceptable to patients and staff and results in improved pain management, it is a low cost intervention which could be widely implemented within the NHS. It also has the potential for being used in other areas such as surgical wards. The investigators have previously found that 300-400 patients per week in the department have moderate to severe pain and might therefore benefit from this monitor.
Interventions
OTHERPIMPERNEL Novel Electronic Log: Pain display can be seen
Pain scores are displayed on the screen when the participant presses the corresponding button
OTHERPIMPERNEL Novel Electronic Log: Pain display is hidden
Participants press the buttons to record their pain score but the score is not on display (the screen is turned backwards).

Inclusion criteria
* adult (18 years and over) * underlying condition giving rise to significant pain (initial VAS pain score of 5 or more) * likely to be staying in the hospital for at least 2 hours * willing and able to give informed consent * able to understand and speak a good level of English
Exclusion criteria
* children (under 18 years) * patients not willing to undergo routine care (analgesic treatment) * patients who do not have capacity to consent * patients who are unwilling or unable to give informed consent * prisoners * patients who cannot understand the study information in English * currently participating in another clinical trial as far as can be determined from information available at the time of assessment * patients who have a physical or visual disability which will prevent them from holding or using the pain display
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pain reported by the patient:11 point numerical pain scale | Up to 6 hours | Data collected from the display using the 11 point numerical pain scale. The area under the curve will be compared between the intervention and control groups. The Numerical Rating Scale is a scale from 0-10 (whole numbers only, where 0 represents 'no pain' and 10 represents 'worst pain ever'). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Comparison of pain recorded on the display (closest minute) with verbal pain assessment at 2 and 4 hours | Up to 6 hours | The scores recorded by the participants at 2 and 4 hours into their hospital stay will be compared with the scores recorded by nursing staff in the electronic record. The 11 point numerical rating scale is used for both measurements. The Numerical Rating Scale is a scale from 0-10 (whole numbers only, where 0 represents 'no pain' and 10 represents 'worst pain ever'). |
| Understanding the pattern of pain (shape of the curve of pain scores) over the time of the ED stay | Up to 6 hours | — |
| Recording time to second dose of analgesia and whether there is a pattern to this | Up to 6 hours | — |
| Proportion of possible scores recorded by patients | Up to 6 hours | — |
| Opinion of patients | Up to 6 hours | Uses a short (4 question) questionnaire designed for this study. Questions on ease of use, whether the monitor is a good idea, whether participants would use it again in the future and whether it improved their experience as a patient, plus a comments box. Questions: 1) How easy was it to use the pain monitor? (very easy, easy, no opinion, difficult, very difficult) 2) I think that the pain monitor is a good idea (strongly agree, agree, no opinion, disagree, strongly disagree) 3) I would use the monitor again in the future (strongly agree, agree, no opinion, disagree, strongly disagree) 4) The pain monitor improved my experience as a patient (strongly agree, agree, no opinion, disagree, strongly disagree) |
| Opinion of staff (including their opinion of whether patients press the button for reasons other than pain) | Up to 6 hours | Short (4 question) questionnaire designed for the study. Questions on whether the display is practical to use in the Emergency Department, whether they think it is a good idea, whether it is likely to improve the patient experience and whether a patient used the display to get their attention for a reason other than pain. Also has a comments box. Questions: 1) The pain display is practical to use in the Emergency Department (strongly agree, agree, no opinion, disagree, strongly disagree) 2) I think that the pain display is a good idea (strongly agree, agree, no opinion, disagree, strongly disagree) 3) The pain display is likely to improve the patient experience (strongly agree, agree, no opinion, disagree, strongly disagree) 4) A patient used the pain display to get my attention for a reason other than pain (yes, not sure, no) |
| Opinion of researchers regarding any likely stratification needs | Up to 6 hours | Subjective opinion of researchers having completed the study on whether stratification would be required in future studies. No specific measurement used. |
| Use of analgesia in intervention and control groups (dose, time prescribed, time administered and name) | Up to 6 hours | The dose, time prescribed, time administered and name of analgesia given pre-hospital and whilst in hospital will be recorded and a comparison made between the groups. This is a feasibility study only so exact outcome depends upon what data can be collected. |
