Acute pain treatment of children in the Danish emergency departments
Children have a high risk of pain underestimation  and insufficient pain treatment of children in the emergency department (ED) is well documented [2-4]. Insufficient pain treatment may have long-term negative effects on the child and their development and is an unpleasant experience [5, 6].
The ED setting may be characterised by a large patient-flow and a stressful atmosphere , rarely producing a child-friendly environment . These factors, in combination with a lack of pain recognition and education in the use of pain assessment tools for children, are possible explanations for the insufficient pain treatment of children in EDs .
Well-implemented guidelines and education that focus on pain treatment for children lead to a significant increase in pain assessment, pain score documentation and use of opioids when relevant, thereby improving pain treatment in children [10, 11]. The present study aimed to clarify whether the Danish EDs have well-implemented guidelines that reflect the national guideline on acute pain treatment of children. We hypothesised that one of the causes explaining insufficient pain treatment of children is that the guidelines differ from the national evidence-based guideline and/or are not well implemented. This was investigated by comparing the local guidelines to a national guideline (seen as the gold standard) and via a structured telephone interview with doctors in the ED.
This cross-sectional study consisted of two parts. In Part I, local guidelines from Danish EDs were collected and compared with the national guideline. In part II, a structural questionnaire was developed and a junior and senior doctor in each ED were interviewed. This study was focused on EDs treating minor and severe traumatic injuries. We did not include the specialised paediatric departments who handle other types of paediatric emergencies.
We included the 21 Danish EDs that take in patients 24 hours/day.
Collection of guidelines
The guidelines were obtained either from public websites or by contacting the ED directly. If the departments used more than one guideline, all guidelines were examined and those containing acute pain treatment were included.
The guidelines were compared with the national guideline, “Acute pain in children” . which was published in 2019. The authors of the national guideline represent the Danish Society for Anaesthesiology and Intensive Medicine, the Danish Society for Emergency Medicine and the Danish Paediatric Society. The collected guidelines were analysed by focusing on the following subjects:
- Pain assessment
- Pharmacological treatment, including:
- Non-pharmacological treatment.
Structured telephone interview
The structured telephone interview was conducted following a questionnaire. The telephone interviews were conducted during weekdays in the daytime from 13 October to 2 December 2021 by MNKH.
Descriptive statistics were used to present actual numbers and percentages. Information from the telephone interviews was registered in RedCap, and the data were analysed in STATA 13. Continuous variables were compared using the chi-squared test. Statistical significance was set at p < 0.05.
This study did not involve any collection of personal data regarding human participants why approval from an ethics committee was not required under Danish law (Committee Act, Section 14, Part 2).
Trial registration: not relevant.
Part I – Guidelines
Twenty (95%) EDs were included in part I, and one (5%) ED never responded to any of our communications regarding their local guideline. Some of the EDs provided more than one guideline. If the EDs referred to both a local and an inter-regional guideline; both guidelines were included; 24 guidelines were included in our study.
Ten (42%) guidelines were developed specially for the ED setting. The remaining EDs used guidelines developed for a different department, mainly paediatric departments (Table 1). The age distribution of the target patient group varied among the guidelines according to the higher and lower age limits established (Table 1).
The national guideline  recommends using the following pain scales to assess children’s pain: COMFORTNeo; face, legs, activity, cry, consolability (FLACC); the Wong-Baker and visual analogue scale (VAS); or the numeric rating scale (NRS). Two (10%) of the EDs referred to the exact same pain assessment tools as the national guideline. However, six (30%) EDs mentioned FLACC, Face scale/Wong-Baker and VAS/NRS, excluding only the scale recommended for neonates (COMFORTNeo) (Table 2). Three (15%) EDs did not include pain assessment for children in any of their guidelines (Table 2).
The national guideline  suggests using paracetamol and ibuprofen for light pain and to add morphine if the patient has moderate to severe pain. If the patient experiences break-through pain, the guideline suggests adding an opioid as required. The appendix of the national guideline contains dose schedules for individual medications.
All 20 (100%) EDs recommended using paracetamol, ibuprofen and morphine as pain medicine. Seven (35%) of the EDs included dose schedules in the guideline and 13 (65%) of the EDs referred to a separate guideline for dose schedules. Three (15%) EDs did not have any dose schedules included in any of their guidelines. Nine (45%) of the EDs mentioned the antidote for morphine, including the dosage scale (Table 2).
The national guideline  emphasises the importance of using non-pharmacological methods for treating pain. Eleven (55%) of the EDs mentioned non-pharmacological management strategies in their guidelines (see Table 3). Eight (30%) of the EDs did not have any guideline concerning non-pharmacological methods (see Table 3).
Part II – Structured telephone interview
Nineteen (91%) of the 21 EDs consented to participate in the telephone interview. Two (11%) EDs only wanted us to contact the senior doctor on call. Three (16%) departments asked that we contact a junior and a senior doctor of their choice. Nineteen senior doctors and 17 junior doctors were interviewed.
Education and local guidelines
All doctors replied that children were a frequent patient group in the ED, and almost all doctors had treated children in the ED. Senior doctors had received education and been introduced to a guideline from the department on managing children in pain more often than junior doctors. All the doctors knew where to find the guideline for acute treatment of pain in children, but only six (35%; 95% confidence interval (CI): 16-62%) of the junior doctors and 13 (68%; 95% CI: 43-86%) of the senior doctors were familiar with the guideline (Table 3).
Two (11%) of the senior doctors answered that they never used the guideline (Figure 1 and Supplementary files: A09220540_-_supplementary.pdf), whereas six (38%) of the junior doctors replied that they never used the guideline (Figure 1 and Supplementary files).
The doctors were asked if the guideline was sufficient to provide the preconditions for providing pain treatment of children. All the junior doctors who answered this question replied either to “a great extent” or “to some extent.” Four (27%; 95% CI: 9-56%) of the senior doctors answered that the guideline was sufficient “to a lesser extent” and one (7%; 95% CI: 1-40%) reported “not at all” (Figure 1 and Supplementary files).
Fifteen (83%) senior doctors and eight (47%) junior doctors reported infrequently using pain assessment for children (Figure 1). Three (17%) senior doctors reported using pain assessment regularly, either “to a great extent” or “to some extent”, whereas nine (53%) of the junior doctors reported using pain assessment regularly (Figure 1).
We asked the doctors if they were less inclined to give opioids to children with a dislocated fracture than to adults with the same type of fracture. Eleven (58%; 95% CI: 34-78%) senior doctors would prescribe opioids to children to the same degree as to adults, and two (13%; 95% CI: 3-42%) of the junior doctors replied the same (Figure 1). In contrast, eight (50%) of the junior doctors and five (26%) of the senior would be less inclined to use opioids for children (Figure 1). Senior doctors were thus significantly (p = 0.02) more inclined to give children opioids than junior doctors.
Seventeen (89%; 95% CI: 64-98%) of the senior doctors and nine (53%; 95% CI: 29-76%) of the junior doctors knew of and used non-pharmacological strategies in the department.
Fifteen (88%) junior doctors and 17 (90%) senior doctors reported that they were competent in treating children in pain (Figure 1).
We found that all EDs had or referred to a guideline on pain treatment of children. These guidelines varied, especially in three areas: 1. pain assessment tools for children were not mentioned in 15% of the EDs’ guidelines; 2. 65% of the EDs did not include a dose schedule for the recommended pharmacological treatments in their guidelines; and 3. 30% of the EDs did not mention non-pharmacological measures. All of the doctors reported that they knew where to find the guidelines, but a considerable share of them did not use them. The majority of the doctors felt competent in treating children. However, they also reported not using pain assessment on children on a regular basis and almost half of the junior doctors did not know any non-pharmacological methods. Furthermore, a clear reluctance was observed to give opioids to children, mostly among junior doctors often working in the ED.
We found that not all guidelines in the EDs contained pain assessment tools for children, which correlates with findings in other studies where a deficiency in pain assessment and documentation has been reported [4, 10, 11]. Pain scores have only been documented in around half of the examined paediatric patients in several studies [4, 13], and a significant association between pain score documentation and use of any analgesic, particularly opioids, in children has been found .
Approximately one third of the EDs had guidelines that included a dosage schedule. The shortage of easily available dosage schedules may be part of the explanation for the documented undertreatment of children in pain [2, 3, 14]. Physicians in the ED have previously expressed that more education and clearer policies are needed to improve the pain treatment of children .
In the telephone interviews, most of the doctors reported that they did not use pain assessment tools “regularly” or “at all” for children. This may possibly be explained by the shortage of pain assessment tools found in the guidelines.
This study shows that 26% of the interviewed senior doctors and 50% of the junior doctors were less inclined towards giving opioids to children than to adult patients. Several previous studies comparing adult and paediatric patients have shown that children receive less analgesia than adults [4, 16, 17], which our findings supported. The overall reluctance to give children opioids has several explanations, i.e. fear that introducing opioids at an early age may lead to addiction, concerns about masking physical signs and concerns about the safety of using and/or over-prescribing narcotics to children [9, 17]. Our study found that only 45% of the EDs had an antidote with a dosage schedule described in their pain treatment guidelines for children, potentially complicating the usage of opioids by children.
Interestingly, both senior and junior doctors reported feeling competent in treating children in pain despite the lack of pain assessment and the reluctance to give opioids. Less than a third of the junior doctors reported having been introduced to a guideline and receiving any education in treating children in pain.
Previously, international studies have found that despite the existence of a guideline and/or a protocol, a gap between recommended care and clinical practice was observed in the EDs. It has been suggested that guideline adherence may be influenced by patient factors (age, time presentation, comorbidity, etc.) and organisational factors (time management and lack of personnel) [18, 19]. Further investigation is this area is highly relevant.
The findings of our study lead us to suggest implementation of a uniform/national guideline including information about who to contact for help and comprising thorough education in acute pain treatment of children, a subject that does not have a strong presence either in medical school or foundation year work.
Strengths and limitations
Part II of this study has some selection biases as two departments did not consent to participating, but also because three departments decided to select the respondents and two departments asked us not to contact the junior doctor on call. Furthermore, telephone interviews have some limitations. The answers may potentially have differed if the phone call had been made on a different day with another interviewer and/or respondent or several doctors in each ED. Furthermore, the answers might be influenced by recollection bias.
This study found that the national guideline is far from well implemented.
We suggest implementing a national guideline in the EDs in Denmark. This would solve the absence of pain assessment tools, non-pharmacological methods and the shortage of dosage schedules in some EDs’ guidelines. Alignment across EDs would ensure that best practices are shared and developed in collaboration. Furthermore, we suggest that an awareness of the under treatment of children in pain be brought to the doctors’ and clinical staff’s attention.
