Do Ethnic Differences Still Exist in Pain Assessment and Treatment in the Emergency Department?

Assessment of adequacy and appropriateness of pain management practice among trauma patients at the Ethiopian Aabet Hospital: A prospective observational study

INTRODUCTION

Pain is unpleasant sensory and emotional experiences associated with actual and/or potential tissue damage. It is the most common and prevalent reason for emergency departments (ED) visits with prevalence over 70% in the world.

AIM OF THE STUDY

The study aimed to assess the adequacy and appropriateness of pain management at Aabet Hospital, Addis Ababa, Ethiopia.

METHODS

A hospital-based prospective cross-sectional study was conducted at Aabet hospital from December 1, 2020 to March 30, 2021. Adult trauma patients having pain (at least score 1 on Numeric Rating Scale) with Glasgow Coma Scale score > 13 were eligible to participate in the study. The pain intensity was evaluated at the time of admission (o minute) and then at 60, 120, 180, and 240 minutes. The time of the first analgesics was registered. The adequacy and the appropriateness of the pain management were calculated through pain management index (PMI).

RESULTS

Two hundred thirty-two (232) participants were included in this study of which 126 (54.3%) were admitted due to road traffic accident followed by fall 44(19%). Only 21 (9.1%) study participants received the first analgesic treatment within 30 minutes while 27(11.6%) participants had no treatment at all within 240 minutes. The mean pain intensity score at admission was 5.55 ± 2.32 and reduced to 4.09 ± 2.69. Nearly half 110 (47.4%) of the study participants were treated inadequately (PMI (-) score). There was a weak and negative correlation between PMI and time to analgesia (r = - .159, p = 0.0001). The type of analgesia used, the time to analgesia, and the degree of pain may predict 65% of the variance in PMI score (R2 = 0.65, P = .001).

CONCLUSION

From the results of this study, it can be concluded that acute pain in trauma patients was under and inappropriately treated.

Racial and ethnic differences in the use of lumbar imaging, opioid analgesics and spinal surgery for low back pain: A systematic review and meta-analysis

BACKGROUND AND OBJECTIVE

There is a substantial gap between evidence and clinical care for low back pain (LBP) worldwide despite recommendations of best practice specified in clinical practice guidelines. The aim of this systematic review was to identify disparities associated with race or ethnicity in the use of lumbar imaging, opioid analgesics, and spinal surgery in people with LBP.

DATABASES AND DATA TREATMENT

We included observational studies which compared the use of lumbar imaging, opioid analgesics, and spinal surgery for the management of non-serious LBP between people from different racial/ethnic populations. We searched in MEDLINE, EMBASE and CINAHL from January 2000 to June 2021. Risk of bias of included studies was appraised in six domains. For each type of care, we pooled data stratified by race and ethnicity using random effects models.

RESULTS

We identified 13 eligible studies; all conducted in the United States. Hispanic/Latino (OR 0.69, 95%CI 0.49-0.96) and Black/African American (OR 0.59, 95%CI 0.46-0.75) people with LBP were less likely to be prescribed opioid analgesics than White people. Black/African Americans were less likely to undergo or be recommended spinal surgery for LBP (OR 0.47, 95%CI 0.33-0.67) than White people. There was a lack of high certainty evidence on racial/ethnic disparities in the use of lumbar imaging.

CONCLUSION

This review reveals lower rate of the use of guideline-discordant care, especially opioid prescription and spinal surgery, in racial/ethnic minority populations with LBP in the United States. Future studies in other countries evaluating care equity for LBP are warranted. PROSPERO Registration ID: CRD42021260668.

SIGNIFICANCE

This systematic review and meta-analysis revealed that people with low back pain from the minority racial/ethnic backgrounds were less likely to be prescribed opioid analgesics and undergo spinal surgery than the majority counterparts. Strategic interventions to improve the access to, and the value of, clinical care for minority populations with low back pain are warranted.

Both Race and Insurance Type Independently Predict the Selection of Oral Opioids Prescribed to Cancer Outpatients

BACKGROUND

Previous research suggests that racial disparities in patients' reported analgesic adverse effects are partially mediated by the type of opioid prescribed to African Americans despite the presence of certain comorbidities, such as renal disease.

AIMS

We aimed to identify independent predictors of the type of opioid prescribed to cancer outpatients and determine if race and chronic kidney disease independently predict prescription type, adjusting for relevant sociodemographic and clinical confounders.

DESIGN

We conducted a secondary analysis of a 3-month observational study.

SETTING

Outpatient oncology clinics of an academic medical center.

PARTICIPANTS/SUBJECTS

Patients were older than 18 years of age, self-identified as African American or White, and had an analgesic prescription for cancer pain.

METHODS

Cancer patients (N = 241) were recruited from outpatient oncology clinics within a large mid-Atlantic healthcare system.

RESULTS

Consistent with published literature, most patients (75.5%) were prescribed either morphine or oxycodone preparations as oral opioid therapy for cancer pain. When compared with Whites, African Americans were significantly more likely to be prescribed morphine (33% vs 14%) and less likely to be prescribed oxycodone (38% vs 64%) (p < .001). The estimated odds for African Americans to receive morphine were 2.573 times that for Whites (95% confidence interval 1.077-6.134) after controlling for insurance type, income, and pain levels. In addition, the presence of private health insurance was negatively associated with the prescription of morphine and positively associated with prescription of oxycodone in separate multivariable models. The presence of chronic kidney disease did not predict type of analgesic prescribed.

CONCLUSIONS

Both race and insurance type independently predict type of opioid selection for cancer outpatients. Larger clinical studies are needed to fully understand the sources and clinical consequences of racial differences in opioid selection for cancer pain.

Racial and ethnic disparities in the management of acute pain in US emergency departments: Meta-analysis and systematic review

OBJECTIVE

This review aims to quantify the effect of minority status on analgesia use for acute pain management in US Emergency Department (ED) settings.

METHODS

We used the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) methodology to perform a review of studies from 1990 to 2018 comparing racial and ethnic differences in the administration of analgesia for acute pain. Studies were included if they measured analgesia use in white patients compared to a racial minority in the ED and studies were excluded if they focused primarily on chronic pain, case reports and survey studies. Following data abstraction, a meta-analysis was performed using fixed and random-effect models to determine primary outcome of analgesia administration stratified by racial and ethnic classification.

RESULTS

763 articles were screened for eligibility and fourteen studies met inclusion criteria for qualitative synthesis. The total study population included 7070 non-Hispanic White patients, 1538 Hispanic, 3125 Black, and 50.3% female. Black patients were less likely than white to receive analgesia for acute pain: OR 0.60 [95%-CI, 0.43-0.83, random effects model]. Hispanics were also less likely to receive analgesia: OR 0.75 [95%-CI, 0.52-1.09].

CONCLUSION

This study demonstrates the presence of racial disparities in analgesia use for the management of acute pain in US EDs. Further research is needed to examine patient reported outcomes in addition to the presence of disparities in other groups besides Black and Hispanic.

Change in Pain Score after Administration of Analgesics for Lower Extremity Fracture Pain during Hospitalization

BACKGROUND

Effective acute pain management following injury is critical to improve short-and long-term patient outcomes. Analgesics can effectively reduce pain intensity, yet half of injury patients report moderate to severe pain during hospitalization.

PURPOSE

The primary aim of this study was to identify the analgesic, different analgesic combinations, or analgesic and adjuvant analgesic combination that generated the largest percent change from pre- to post-analgesic pain score.

DESIGN

This was a descriptive retrospective cohort study of 129 adults admitted with lower extremity fractures to a trauma center.

METHODS

Name, dose, and frequency of analgesics and adjuvant analgesics administered from admission to discharge were collected from medical records. Percent change was calculated from pain scores documented on the 0-10 numeric rating scale.

RESULTS

The analgesic with largest percent change from pre- to post-administration pain score was hydromorphone 2 mg IV (53%) for the emergency department and morphine 4 mg IV (54%) for the in-patient unit. All analgesics administered in the emergency department and ∼50% administered on the in-patient unit produced a minimal (15%) decrease in pain score.

CONCLUSIONS

This study revealed that few analgesics administered in the emergency department and the in-patient unit to patients with lower extremity fractures provide adequate pain relief. In the emergency department, all analgesics administered resulted in at least minimal improvement of pain. On the in-patient unit 13 analgesic doses resulted at least minimal improvement in pain while nine doses did not even reach 20% change in pain. Findings from this study can be used guide the treatment of fracture pain in the hospital.

Analgesics Administered for Pain During Hospitalization Following Lower Extremity Fracture: A Review of the Literature

Effective treatment of acute pain during hospitalization following lower extremity fracture is critical to improve short-term patient outcomes including wound healing, stress response, hospital length of stay, and cost as well as minimizing long-term negative patient outcomes such as delayed return to work, disability, and chronic pain. As many patients report moderate to severe pain during hospitalization, identifying the analgesics that most effectively reduces pain is a priority to improve patient outcomes. The purpose of this review was to examine published studies describing patient response to analgesics administered orally (PO) or intravenously (IV) in the immediate hospitalization following lower extremity fracture. PubMed was queried for articles published through May 2017 that included information on type of study, population, fracture site, pain measurement tool, analgesic, and result. Of 514 articles found, eight met the inclusion criteria. Analgesics administered PO or IV were fentanyl, hydromorphone, morphine, remifentanil, diclofenac, ibuprofen, ketorolac, and etoricoxib. Five of the studies focused on comparisons between one or more analgesics and three studies compared an IV analgesic to a regional anesthetic agent. Two studies compared different nonsteroidal anti-inflammatory drugs (NSAIDs). Bupivacaine, lignocaine, and levobupivacaine administered as regional nerve blocks were superior to controlling pain compared with IV fentanyl and IV hydromorphone. IV morphine provided faster and better pain relief compared with IV ibuprofen. Based on the limited data available, regional nerve blocks provided superior pain relief compared with opioids, and opioids provided superior pain relief compared with NSAIDs. Different NSAIDs provided similar pain relief.

Demographic, Clinical, and Health System Characteristics Associated With Pain Assessment Documentation and Pain Severity in U.S. Military Patients in Combat Zone Emergency Departments, 2010-2013

Emergency department (ED) pain assessment documentation in trauma patients is critical to ED pain care. This retrospective, cross-sectional study used trauma registry data to evaluate U.S. military combat zone trauma patients injured between 2010 and 2013 requiring ≥ 24-hr inpatient care. Study aims were to identify the frequency of combat zone ED pain assessment documentation and describe pain severity. Secondary aims were to construct statistical models to explain variation in pain assessment documentation and pain severity.Pain scores were documented in 60.5% (n = 3,339) of the 5,518 records evaluated. The proportion of records with ED pain scores increased yearly. Pain assessment documentation was associated with documentation of ED vital signs, comprehensive facility, more recent year, prehospital (PH) heart rate of 60-100 beats/min, ED Glasgow Coma Scale score of 15 vs. 14, blunt trauma, and lower injury severity score (ISS).Pain severity scores ranged from 0 to 10; mean = 5.5 (SD = 3.1); median = 6. Higher ED pain scores were associated with Army service compared with Marine Corps, no documented PH vital signs, higher PH pain score, ED respiratory rate < 12 or >16, moderate or severe ISS compared with minor ISS, treatment in a less-equipped facility, and injury in 2011 or 2012 vs. 2010. The pain severity model explained 20.4% of variance in pain severity.Overall, frequency of pain assessment documentation in combat-zone EDs improved yearly, but remained suboptimal. Pain severity was poorly predicted by demographic, clinical, and health system variables available from the trauma registry, emphasizing the importance of individual assessment.

Acute Pain Characteristics in Patients with and without Chronic Pain following Lower Extremity Injury

Many patients with injuries to lower extremities report chronic pain. High pain intensity at time of admission for injury is a risk factor for chronic pain, but it is not clear whether specific acute pain patterns following injury influence the development of chronic pain. To examine the relationship between the pain trajectory, the mean pain score, and the frequency of pain documentation during the immediate hospitalization following injury, with the report of chronic pain. This was a descriptive, retrospective cohort study of adults admitted with lower extremity fractures to an academic urban trauma center. Participants, 6-45 months postinjury, rated their current pain, worst pain, and average pain over the last 3 months. Pain scores from hospitalization associated with the injury were obtained through a retrospective chart review. The pain trajectory, mean pain score, and frequency of pain documentation was compared between patients with and without chronic pain. A total of 129 patients were enrolled in this study and 78% reported chronic pain at the site of injury. The mean pain score (5.1 vs. 4.2) and first pain score (5.6 vs. 3.4) were higher for patients with chronic pain compared to patients with no chronic pain. Consistent with other studies, high pain intensity at time of injury was associated with chronic pain. The findings contribute valuable information about acute pain characteristics associated with chronic pain and provide insight into the importance of early and adequate acute pain treatment.

Efficacy of Intravenous Paracetamol Versus Intravenous Morphine in Acute Limb Trauma

Background:

Efficient pain management is one of the most important components of care in the field of emergency medicine.

Objectives:

This study was conducted to compare intravenous paracetamol and intravenous morphine sulfate for acute pain reduction in patients with limb trauma.

Patients and Methods:

In a randomized double-blinded clinical trial, all patients (aged 18 years and older) with acute limb trauma and a pain score of greater than 3/10 in the emergency department were recruited; they received either 1 g intravenous paracetamol or 0.1 mg/kg intravenous morphine sulfate over 15 minutes. The primary outcome was the pain score measured on a numerical rating scale at 0, 15 and 30 minutes after commencing drug administration. The requirement for rescue analgesia and the frequency of adverse reactions were also recorded.

Results:

Sixty patients randomly received either IV paracetamol (n = 30) or IV morphine (n = 30). The mean reduction in numerical rating scale pain intensity scores at 30 minutes was 3.86 (± 1.61) for paracetamol, and 2.16 (± 1.39) for morphine. However, pain relief was significantly higher in the paracetamol group compared to the morphine group (P < 0.001). Four patients in the paracetamol group and 15 patients in the morphine group needed rescue analgesia and the difference was significant (P = 0.05).

Conclusions:

Intravenous paracetamol appears to provide better analgesia than intravenous morphine in acute limb trauma. Further larger studies are required.

Characteristics of Patients with Lower Extremity Trauma with Improved and Not Improved Pain During Hospitalization: A Pilot Study

Up to 62% of patients report chronic pain at the injury site 6-12 months after blunt trauma, with pain from lower extremity fractures exceeding that from other sites. High pain intensity at time of injury is a risk factor for chronic pain, but it is not clear what patient characteristics influence the pain intensity level during the immediate hospitalization following injury. The purpose of this pilot study was to determine the feasibility of collecting pain scores from medical records to calculate pain trajectories and to determine whether it is possible to examine patient characteristics by classifying them into those whose pain improved and those whose pain did not improve. This descriptive study retrospectively reviewed medical records of 18 randomly chosen patients admitted to an academic trauma center. Patient characteristics and pain scores were collected form electronic and handwritten medical records. The pain trajectories calculated from routinely collected pain scores during the inpatient stay showed that for 44% of patients the pain improved during the hospitalization, for 39% the pain remained the same, and for 17% the pain worsened. The variables age, smoking, weight, abbreviated injury scores, length of hospital stay, mean pain score, and opioid equianalgesic dose differed based on pain trajectory. While patient characteristics differed based on pain trajectory, any significant effects seen from individual tests should be considered tentative, given the number of analyses conducted on this data set. However, feasibility and significance of conducting a larger study has been established.

Assessment of pain in a Norwegian Emergency Department

Background

Although pain management is a fundamental aspect of care in emergency departments (EDs), inadequate treatment of pain is unfortunately common. There are multiple local protocols for pain assessment in the ED. This study evaluated whether the initial assessment and treatment of pain in the ED are in accordance with the in-hospital protocol of the ED at a Norwegian University Hospital.

Materials and methods

Prospective data on pain assessment and initial treatment in the ED were collected from nursing and physician documentation. The patients’ perceptions of subjective pain were recorded using a numerical rating scale (NRS) that ranged from 0 to 10.

Results

Seventy-seven percent of the 764 enrolled patients were evaluated for pain at arrival. Female patients had a higher probability of not being asked about pain, but there was no difference in the percentage of patients asked about pain with respect to age. Additionally, patients with low oxygen saturation and systolic blood pressure were less likely to be asked about pain. Of those with moderate and severe pain (58 %), only 14 % received pain relief.

Discussion

Assessment and treatment of pain in the ED are inadequate and not in line with the local protocols. A focus on strategies to improve pain treatment in the ED is a necessary aspect of developing optimal acute patient care in Norway in the future.
