Derivation of an abbreviated instrument for use in emergency department low back pain research: the five-item Roland Morris Questionnaire

Barriers and Best Practices for the Use of Patient-Reported Outcome Measures in Emergency Medicine

Patient-reported outcome measures are commonly used in clinical trials and have been incorporated into routine clinical care in select specialties but have not been widely implemented in emergency medicine research and clinical care. We describe measurement-related barriers to patient-reported outcome measure use in the emergency department; administrative and practical considerations; implications of developing novel emergency medicine-specific patient-reported outcome measures; and key considerations for the use of patient-reported outcome measures in emergency medicine research and clinical care. Despite the unique barriers of the ED environment, potential solutions include the use of ED-validated patient-reported outcome measures when available; adapting existing short-form, multidimensional patient-reported outcome measures previously validated in diverse populations, ideally using computer-adapted testing; and collecting responses during anticipated wait times. With this work, we aim to inform barriers and best practices to the use of patient-reported outcome measures in emergency medicine research and clinical care to support future, more widespread implementation of patient-reported outcome measures within emergency care. The successful adoption of patient-reported outcome measures for diverse ED patient populations within the unique constraints of the acute care environment may help researchers, clinicians, and policymakers improve the quality and patient-centeredness of acute care.

Emergency department interventions for adult patients with low back pain: a systematic review of randomised controlled trials

BACKGROUND

Most low back pain trials have limited applicability to the emergency department (ED) because they provide treatment and measure outcomes after discharge from the ED. We investigated the efficacy and safety of pharmacological and non-pharmacological interventions delivered in the ED to patients with non-specific low back pain and/or sciatica on patient-relevant outcomes measured during the emergency visit.

METHODS

Literature searches were performed in MEDLINE, EMBASE and CINAHL from inception to week 1 February 2020. We included all randomised controlled trials investigating adult patients (≥18 years) with non-specific low back pain and/or sciatica presenting to ED. The primary outcome of interest was pain intensity. Two reviewers independently screened the full texts, extracted the data and assessed risk of bias of each trial using the Physiotherapy Evidence Database (PEDro) scale. The overall quality of evidence, or certainty, provided by a set of trials evaluating the same treatment was evaluated using the Grading of Recommendations Assessment, Development and Evaluation (GRADE) approach, which considers imprecision, inconsistency, indirectness and bias in the evidence.

RESULTS

Fifteen trials (1802 participants) were included with 12 of 15 at low risk of bias (ie, PEDro score >6). Based on results from individual trials and moderate quality evidence, ketoprofen gel was more effective than placebo for non-specific low back pain at 30 min (mean difference (MD) -15.0, 95% confidence interval (CI) -21.0 to -9.0). For those with sciatica (moderate quality evidence), intravenous paracetamol (acetaminophen) (MD -15.7, 95% CI -19.8 to -11.6) and intravenous morphine (MD -11.4, 95% CI -21.6 to -1.2) were both superior to placebo at 30 min. Based on moderate quality of evidence, corticosteroids showed no benefits against placebo at emergency discharge for non-specific low back pain (MD 9.0, 95% CI -0.71 to 18.7) or sciatica (MD -6.8, 95% CI -24.2 to 10.6). There were conflicting results from trials comparing different pharmacological options (moderate quality evidence) or investigating non-pharmacological treatments (low quality evidence).

CONCLUSION

Ketoprofen gel for non-specific low back pain and intravenous paracetamol or morphine for sciatica were superior to placebo, whereas corticosteroids were ineffective for both conditions. There was conflicting evidence for comparisons of different pharmacological options and those involving non-pharmacological treatments. Additional trials measuring important patient-related outcomes to EDs are needed.
