IntroductionThis study aims to assess the feasibility of acupuncture as an add-on intervention for patients with non-emergent acute musculoskeletal pain and primary headache in an emergency department (ED) setting.Methods and analysisA total of 40 patients who present to the ED and are diagnosed to have acute non-specific neck pain, ankle sprain or primary headache will be recruited by ED physicians. An intravenous or intramuscular injection of analgesics will be provided as the initial standard pain control intervention for all patients. Patients who still have moderate to severe pain after the 30 min of initial standard ED management will be considered eligible. These patients will be allocated in equal proportions to acupuncture plus standard ED management or to standard ED management alone based on computer-generated random numbers concealed in opaque, sealed, sequentially numbered envelopes. A 30 min session of acupuncture treatment with manual and/or electrical stimulation will be provided by qualified Korean medicine doctors. All patients will receive additional ED management at the ED physician's discretion and based on each patient's response to the allocated intervention. The primary outcome will be pain reduction measured at discharge from the ED by an unblinded assessor. Adverse events in both groups will be documented. Other outcomes will include the patient-reported overall improvement, disability due to neck pain (only for neck-pain patients), the treatment response rate, the use of other healthcare resources and the patients’ perceived effectiveness of the acupuncture treatment. A follow-up telephone interview will be conducted by a blinded assessor 72±12 h after ED discharge.Ethics and disseminationWritten informed consent will be obtained from all participants. The study has been approved by the Institutional Review Boards (IRBs). The results of this study will guide a full-scale randomised trial of acupuncture in an ED context.Trial registration numberClinicalTrials.gov: NCT02013908.
ObjectiveWe aimed to evaluate the factors influencing treatment option selection among urologists for patients with ureteral stones, according to the stone diameter and location.MethodsWe retrospectively reviewed the records of 360 consecutive patients who, between January 2009 and June 2014, presented to the emergency department with renal colic and were eventually diagnosed with urinary stones via computed tomography. The maximal horizontal and longitudinal diameter and location of the stones were investigated. We compared parameters between patients who received urological intervention (group 1) and those who received medical treatment (group 2).ResultsAmong the 360 patients, 179 (49.7%) had stones in the upper ureter and 181 (50.3%) had stones in the lower ureter. Urologic intervention was frequently performed in cases of upper ureteral stones (P<0.001). In groups 1 and 2, the stone horizontal diameters were 5.5 mm (4.8 to 6.8 mm) and 4.0 mm (3.0 to 4.6 mm), stone longitudinal diameters were 7.5 mm (6.0 to 9.5 mm) and 4.4 mm (3.0 to 5.5 mm), and ureter diameters were 6.4 mm (5.0 to 8.0 mm) and 4.7 mm (4.0 to 5.3 mm), respectively (P<0.001). The cut-off values for the horizontal and longitudinal stone diameters in the upper ureter were 4.45 and 6.25 mm, respectively (sensitivity 81.3%, specificity 91.4%); those of the lower ureter were 4.75 and 5.25 mm, respectively (sensitivity 79.4%, specificity 79.4%).ConclusionThe probability of a urologic intervention was higher for patients with upper ureteral stones and those with stone diameters exceeding 5 mm horizontally and 6 mm longitudinally.
