Outcomes after intravenous opioids in emergency patients: a prospective cohort analysis

Regional anaesthesia for rib fractures: A pilot study of serratus anterior plane block

OBJECTIVE

Rib fractures are not only painful but are associated with morbidity and mortality, especially in older patients. The serratus anterior plane block (SAPB) is a plane block distant from major neurovascular bundles and may provide anaesthesia to a substantial area of the hemithorax. This pilot study was designed to assess if the SAPB can be safely and efficiently incorporated to the trauma reception workflow of an adult, level 1 trauma centre.

METHODS

A convenience sample of 20 adult patients with at least two or more unilateral rib fractures received a SAPB performed by an emergency physician in addition to their standard analgesic regime. Time to perform the procedure, the number of attempts and complications were recorded as feasibility measures. Secondary outcome was the safety of the block. Numerical pain scores at pre-determined time points over 4 h, the diagnosis of hospital-acquired pneumonia, hospital length of stay and mortality at hospital discharge were collected to provide pilot data on effectiveness.

RESULTS

The median time to perform the procedure was 5.5 (interquartile range 4.6-10) mins with a range of 2-10.5 min. Most (16; 80%) SAPBs were completed in a single attempt. There were no documented complications. Median pain scores reduced from 6.5 (6-8) and were maintained at 3 (2-5) at 4 h after the SAPB.

CONCLUSIONS

The present study demonstrated the feasibility of ultrasound-guided SAPB among patients with multiple rib fractures in the ED. No complications were observed. Further prospective evaluation of analgesic effects in a larger cohort is indicated.

Factors associated with refractory pain in emergency patients admitted to emergency general surgery

BACKGROUND

Oligoanalgesia in emergency departments (EDs) is multifactorial. A previous study reported that emergency providers did not adequately manage patients with severe pain despite objective findings for surgical pathologies. Our study aims to investigate clinical and laboratory factors, in addition to providers' interventions, that might have been associated with oligoanalgesia in a group of ED patients with moderate and severe pains due to surgical pathologies.

METHODS

We conducted a retrospective study of adult patients who were transferred directly from referring EDs to the emergency general surgery (EGS) service at a quaternary academic center between January 2014 and December 2016. Patients who were intubated, did not have adequate records, or had mild pain were excluded. The primary outcome was refractory pain, which was defined as pain reduction <2 units on the 0-10 pain scale between triage and ED departure.

RESULTS

We analyzed 200 patients, and 58 (29%) had refractory pain. Patients with refractory pain had significantly higher disease severity, serum lactate (3.4±2.0 mg/dL vs. 1.4±0.9 mg/dL, P=0.001), and less frequent pain medication administration (median [interquartile range], 3 [3-5] vs. 4 [3-7], P=0.001), when compared to patients with no refractory pain. Multivariable logistic regression showed that the number of pain medication administration (odds ratio [OR] 0.80, 95% confidence interval [95% CI] 0.68-0.98) and ED serum lactate levels (OR 3.80, 95% CI 2.10-6.80) were significantly associated with the likelihood of refractory pain.

CONCLUSIONS

In ED patients transferring to EGS service, elevated serum lactate levels were associated with a higher likelihood of refractory pain. Future studies investigating pain management in patients with elevated serum lactate are needed.

APOLLO-1: a randomized placebo and active-controlled phase III study investigating oliceridine (TRV130), a G protein-biased ligand at the µ-opioid receptor, for management of moderate-to-severe acute pain following bunionectomy

Purpose

Oliceridine is a novel G protein-biased µ-opioid receptor agonist designed to provide intravenous (IV) analgesia with a lower risk of opioid-related adverse events (ORAEs) than conventional opioids.

Patients and methods

APOLLO-1 (NCT02815709) was a phase III, double-blind, randomized trial in patients with moderate-to-severe pain following bunionectomy. Patients received a loading dose of either placebo, oliceridine (1.5 mg), or morphine (4 mg), followed by demand doses via patient-controlled analgesia (0.1, 0.35, or 0.5 mg oliceridine, 1 mg morphine, or placebo). The primary endpoint compared the proportion of treatment responders through 48 hours for oliceridine regimens and placebo. Secondary outcomes included a composite measure of respiratory safety burden (RSB, representing the cumulative duration of respiratory safety events) and the proportion of treatment responders vs morphine.

Results

Effective analgesia was observed for all oliceridine regimens, with responder rates of 50%, 62%, and 65.8% in the 0.1 mg, 0.35 mg, and 0.5 mg regimens, respectively (all P<0.0001 vs placebo [15.2%]; 0.35 mg and 0.5 mg non-inferior to morphine). RSB showed a dose-dependent increase across oliceridine regimens (mean hours [SD]: 0.1 mg: 0.04 [0.33]; 0.35 mg: 0.28 [1.11]; 0.5 mg: 0.8 [3.33]; placebo: 0 [0]), but none were statistically different from morphine (1.1 [3.03]). Gastrointestinal adverse events also increased in a dose-dependent manner in oliceridine regimens (0.1 mg: 40.8%; 0.35 mg: 59.5%; 0.5 mg: 70.9%; placebo: 24.1%; morphine: 72.4%). The odds ratio for rescue antiemetic use was significantly lower for oliceridine regimens compared to morphine (P<0.05).

Conclusion

Oliceridine is a novel and effective IV analgesic providing rapid analgesia for the relief of moderate-to-severe acute postoperative pain compared to placebo. Additionally, it has a favorable safety and tolerability profile with regard to respiratory and gastrointestinal adverse effects compared to morphine, and may provide a new treatment option for patients with moderate-to-severe postoperative pain where an IV opioid is required.

Essential pharmacologic options for acute pain management in the emergency setting

Pain is the root cause for the overwhelming majority of emergency department (ED) visits worldwide. However, pain is often undertreated due to inappropriate analgesic dosing and ineffective utilization of available analgesics. It is essential for emergency providers to understand the analgesic armamentarium at their disposal and how it can be used safely and effectively to treat pain of every proportion within the emergency setting. A 'balanced analgesia' regimen may be used to treat pain while reducing the overall pharmacologic side effect profile of the combined analgesics. Channels-Enzymes-Receptors Targeted Analgesia (CERTA) is a multimodal analgesic strategy incorporating balanced analgesia by shifting from a system-based to a mechanistic-based approach to pain management that targets the physiologic pathways involved in pain signaling transmission. Targeting individual pain pathways allows for a variety of reduced-dose pharmacologic options - both opioid and non-opioid - to be used in a stepwise progression of analgesic strength as pain advances up the severity scale. By developing a familiarity with the various analgesic options at their disposal, emergency providers may formulate safe, effective, balanced analgesic combinations unique to each emergency pain presentation.

Assessing adequacy of emergency provider documentation among interhospital transferred patients with acute aortic dissection

BACKGROUND

Acute aortic dissection (AoD) is a hypertensive emergency often requiring the transfer of patients to higher care hospitals; thus, clinical care documentation and compliance with the Emergency Medical Treatment and Active Labor Act (EMTALA) is crucial. The study assessed emergency providers (EP) documentation of clinical care and EMTALA compliance among interhospital transferred AoD patients.

METHODS

This retrospective study examined adult patients transferred directly from a referring emergency department (ED) to a quaternary academic center between January 1, 2011 and September 30, 2015. The primary outcome was the percentage of records with adequate documentation of clinical care (ADoCC). The secondary outcome was the percentage of records with adequate documentation of EMTALA compliance (ADoEMTALA).

RESULTS

There were 563 electronically identified patients with 287 included in the final analysis. One hundred and five (36.6%) patients had ADoCC while 166 (57.8%) patients had ADoEMTALA. Patients with inadequate documentation of EMTALA (IDoEMTALA) were associated with a higher likelihood of not meeting the American Heart Association (AHA) ED Departure SBP guideline (OR 1.8, 95% CI 1.03-3.2, P=0.04). Male gender, handwritten type of documentation, and transport by air were associated with an increased risk of inadequate documentation of clinical care (IDoCC), while receiving continuous infusion was associated with higher risk of IDoEMTALA.

CONCLUSION

Documentation of clinical care and EMTALA compliance by Emergency Providers is poor. Inadequate EMTALA documentation was associated with a higher likelihood of patients not meeting the AHA ED Departure SBP guideline. Therefore, Emergency Providers should thoroughly document clinical care and EMTALA compliance among this critically ill group before transfer.

Emergency Providers' Pain Management in Patients Transferred to Intensive Care Unit for Urgent Surgical Interventions

Introduction

Pain is the most common complaint for an emergency department (ED) visit, but ED pain management is poor. Reasons for poor pain management include providers’ concerns for drug-seeking behaviors and perceptions of patients’ complaints. Patients who had objective findings of long bone fractures were more likely to receive pain medication than those who did not, despite pain complaints. We hypothesized that patients who were interhospital-transferred from an ED to an intensive care unit (ICU) for urgent surgical interventions would display objective pathology for pain and thus receive adequate pain management at ED departure.

Methods

This was a retrospective study at a single, quaternary referral, academic medical center. We included non-trauma adult ED patients who were interhospital-transferred and underwent operative interventions within 12 hours of ICU arrival between July 2013 and June 2014. Patients who had incomplete ED records, required invasive mechanical ventilation, or had no pain throughout their ED stay were excluded. Primary outcome was the percentage of patients at ED departure achieving adequate pain control of ≤ 50% of triage level. We performed multivariable logistic regression to assess association between demographic and clinical variables with inadequate pain control.

Results

We included 112 patients from 39 different EDs who met inclusion criteria. Mean pain score at triage and ED departure was 8 (standard deviation 8 and 5 [3]), respectively. Median of total morphine equivalent unit (MEU) was 7.5 [5–13] and MEU/kg total body weight (TBW) was 0.09 [0.05–0.16] MEU/kg, with median number of pain medication administration of 2 [1–3] doses. Time interval from triage to first narcotic dose was 61 (35–177) minutes. Overall, only 38% of patients achieved adequate pain control. Among different variables, only total MEU/kg was associated with significant lower risk of inadequate pain control at ED departure (adjusted odds ratio = 0.22; 95% confidence interval = 0.05–0.92, p = 0.037).

Conclusion

Pain control among a group of interhospital-transferred patients requiring urgent operative interventions, was inadequate. Neither demographic nor clinical factors, except MEU/kg TBW, were shown to associate with poor pain management at ED departure. Emergency providers should consider more effective strategies, such as multimodal analgesia, to improve pain management in this group of patients.

Evaluation of Emergency Department Management of Opioid-Tolerant Cancer Patients With Acute Pain

CONTEXT

There are no previously published studies examining opioid doses administered to opioid-tolerant cancer patients during emergency department (ED) encounters.

OBJECTIVES

To determine if opioid-tolerant cancer patients presenting with acute pain exacerbations receive adequate initial doses of as needed (PRN) opioids during ED encounters based on home oral morphine equivalent (OME) use.

METHODS

We performed a retrospective cohort study of opioid-tolerant cancer patients who received opioids in our ED over a two-year period. The percentage of patients who received an adequate initial dose of PRN opioid (defined as ≥10% of total 24-hour ambulatory OME) was evaluated. Logistic regression was used to establish the relationship between 24-hour ambulatory OME and initial ED OME to assess whether higher home usage was associated with higher likelihood of being undertreated.

RESULTS

Out of 216 patients, 61.1% of patients received an adequate initial PRN dose of opioids in the ED. Of patients taking <200 OMEs per day at home, 77.4% received an adequate initial dose; however, only 3.2% of patients taking >400 OMEs per day at home received an adequate dose. Patients with ambulatory 24-hour OME greater than 400 had 99% lower odds of receiving an adequate initial dose of PRN opioid in the ED compared to patients with ambulatory 24-hour OME less than 100 (OR <0.01, CI 0.00-0.02, P < 0.001).

CONCLUSIONS

Patients with daily home use less than 200 OMEs generally received adequate initial PRN opioid doses during their ED visit. However, patients with higher home opioid usage were at increased likelihood of being undertreated.

Pain Management for Older African Americans in the Perianesthesia Setting: The "Eight I's"

National legislation (Affordable Care Act) emphasizes quality and equitable pain care for all patient populations, but frequently, pain management is not effective and equitable in African American (AA) elders, placing them at higher risk for severe pain and persistent pain. Research shows that AAs are less likely to receive guideline-based pain care. This underscores the need for perianesthesia nurses to be knowledgeable and capable of integrating cultural practices and evidence-based recommendations into their care of older AAs to ensure adequate pain management in this vulnerable population. This article describes differences and disparities in pain management in AA older adults and provides a cultural framework to guide perianesthesia pain management.

Predicting morphine related side effects in the ED: An international cohort study

STUDY OBJECTIVES

Morphine is the reference treatment for severe acute pain in an emergency department. The purpose of this study was to describe and analyse opioid-related ADRs (adverse drug reactions) in a large cohort of emergency department patients, and to identify predictive factors for those ADRs.

METHODS

In this prospective, observational, pharmaco-epidemiological international cohort study, all patients aged 18years or older who were treated with morphine were enrolled. The study was done in 23 emergency departments in the US and France. Baseline numerical rating scale score and initial and total doses of morphine titration were recorded. Logistic regression analysis was used to study the effects of demographic, clinical and medical history covariates on the occurrence of opioid-induced ADRs within 6h after treatment.

RESULTS

A total of 1128 patients were included over 10months. Median baseline initial pain scores were 8/10 (7-10) versus 3/10 (1-4) after morphine administration. Median titration duration was 10min (IQR, 1-30). The occurrence of opioid-induced ADRs was 25% and 2% were serious. Patients experienced mainly nausea and drowsiness. Medical history of travel sickness (odds ratio [OR], 1.7; 95% confidence interval [CI], 1.01-2.86) and history of nausea or vomiting post morphine (OR, 3.86; 95% CI, 2.29-6.51) were independent predictors of morphine related ADRs.

CONCLUSION

Serious morphine related ADRs are rare and unpredictable. Prophylactic antiemetic therapy could be proposed to patients with history of travel sickness and history of nausea or vomiting in a postoperative setting or after morphine administration.

Culturally Conscientious Pain Measurement in Older African Americans

Despite considerable pain disparities across the care continuum, pain is an understudied health problem in older ethnic minority groups, such as African Americans. Quality pain measurement is a core task in pain management and a mechanism by which pain disparities may be reduced. Pain measurement includes the methods (e.g., assessment approaches, tools) and metrics that researchers and clinicians use to understand the characteristics of pain. However, there are significant issues and gaps that negatively affect pain measurement in older African Americans. Of concern is insufficient representation in pain research, which impedes the testing and refinement of many standardized self-report, behavioral and surrogate report, physiological, and composite measures of pain. The purposes for this article are to discuss the status of pain measurement and factors that affect our knowledge on pain measurement in older African Americans, and to provide guidance for culturally conscientious pain measurement using the available literature.

Acceptability, Adaptation, and Clinical Outcomes of Acupuncture Provided in the Emergency Department: A Retrospective Pilot Study

Objective

To evaluate acceptability and clinical outcomes of acupuncture on patient-reported pain and anxiety in an emergency department (ED).

Design

Observational, retrospective pilot study.

Setting

Abbott Northwestern Hospital ED, Minneapolis, MN.

Methods

Retrospective data was used to identify patients receiving acupuncture in addition to standard medical care in the ED between 11/1/13 and 12/31/14. Feasibility was measured by quantifying the utilization of acupuncture in a novel setting and performing limited tests of its efficacy. Patient-reported pain and anxiety scores were collected by the acupuncturist using an 11-point (0-10) numeric rating scale before (pre) and immediately after (post) acupuncture. Efficacy outcomes were change in pain and anxiety scores.

Results

During the study period, 436 patients were referred for acupuncture, 279 of whom were approached by the acupuncturist during their ED visit. Consent for acupuncture was obtained from 89% (248/279). A total of 182 patients, who had a pre-pain score >0 and non-missing anxiety scores, were included in analyses. Of the 52% (94/182) who did not have analgesics before or during the acupuncture session, the average decrease of 2.37 points (95% CI: 1.92, 2.83) was not different (p > 0.05) than the mean decrease of 2.68 points for those receiving analgesics (95% CI 2.21, 3.15). The average pre-anxiety score was 4.73 points (SD = 3.43) and the mean decrease was 2.27 points (95% CI: 1.89, 2.66).

Conclusions

Results from this observational trial indicate that acupuncture was acceptable and effective for pain and anxiety reduction, in conjunction with standard medical care. These results will inform future randomized trials.

Improving acute pain management in emergency medicine

Undertreatment of pain (oligoanalgesia) in the emergency department is common, and it negatively impacts patient care. Both failure of appropriate pain assessment and the potential for unsafe analgesic use contribute to the problem. As a result, achieving satisfactory analgesia while minimizing side effects remains particularly challenging for emergency physicians, both in the emergency department and after a patient is discharged. Improvements in rapid pain assessment and in evaluation of noncommunicative populations may result in a better estimation of which patients require analgesia and how much pain is present. New formulations of available treatments, such as rapidly absorbed, topical, or intranasal nonsteroidal anti-inflammatory drug formulations or intranasal opioids, may provide effective analgesia with an improved risk-benefit profile. Other pharmacological therapies have been shown to be effective for certain pain modalities, such as the use of antidepressants for musculoskeletal pain, γ-aminobutyric acid agonists for neuropathic and postsurgical pain, antipsychotics for headache, and topical capsaicin for neuropathic pain. Nonpharmacological methods of pain control include the use of electrical stimulation, relaxation therapies, psychosocial/manipulative therapies, and acupuncture. Tailoring of available treatment options to specific pain modalities, as well as improvements in pain assessment, treatment options, and formulations, may improve pain control in the emergency department setting and beyond.

Pain treatment for older adults during prehospital emergency care: variations by patient gender and pain severity

Older adults are less likely than younger adults to receive analgesic treatment during emergency department visits. Whether older adults are less likely to receive analgesics during protocolized prehospital care is unknown. We analyzed all ambulance transports in 2011 in the state of North Carolina and compared the administration of any analgesic or an opioid among older adults (aged 65 and older) versus adults aged 18 to 64. Complete data were available for 407,763 transports. Older men were less likely than younger men to receive an analgesic or an opioid regardless of pain severity. Among women with mild or moderate pain, older women were less likely than younger women to receive either form of pain treatment, but among women with more severe pain (pain score 8 or more), older women were more likely than younger women to receive pain treatment. Further, among women with mild or moderate pain, the oldest patients (aged 85 and older) were the least likely to receive any analgesic or an opioid, but among women with severe pain the oldest patients were the most likely to receive treatment. Further research is needed to assess the generalizability of this interaction between age, gender, and pain severity on pain treatment.

PERSPECTIVE

During prehospital care in North Carolina in 2011, older adults were generally less likely to receive pain treatment. However, older women with severe pain were more likely to receive treatment than younger women with severe pain. These results suggest an interaction between age, gender, and pain severity on pain treatment.

How do emergency physicians interpret prescription narcotic history when assessing patients presenting to the emergency department with pain?

CONTEXT

Narcotics are frequently prescribed in the Emergency Department (ED) and are increasingly abused. Prescription monitoring programs affect prescribing by Emergency Physicians (EPs), yet little is known on how EPs interpret prescription records.

OBJECTIVE

To assess how EPs interpret prescription narcotic history for patients in the ED with painful conditions. DESIGN/MAIN Outcome Measures: We created an anonymous survey of EPs consisting of fictitious cases of patients presenting to the ED with back pain. For each case, we provided a prescription history that varied in the number of narcotic prescriptions, prescribing physicians, and narcotic potency. Respondents rated how likely they thought each patient was drug seeking, and how likely they thought that the prescription history would change their prescribing behavior. We calculated κ values to evaluate interobserver reliability of physician assessment of drug-seeking behavior.

RESULTS

We collected 59 responses (response rate = 70%). Respondents most suspected drug seeking in patients with greater than 6 prescriptions per month or greater than 6 prescribing physicians in 2 months. Medication potency did not affect physician interpretation of drug seeking. Respondents reported that access to a prescription history would change their prescribing practice in all cases. κ values for assessment of drug seeking demonstrated moderate agreement.

CONCLUSION

A greater number of prescriptions and a greater number of prescribing physicians in the prescription record increased suspicion for drug seeking. EPs believed that access to prescription history would change their prescribing behavior, yet interobserver reliability in the assessment of drug seeking was moderate.

How Frequently are "Classic" Drug-Seeking Behaviors Used by Drug-Seeking Patients in the Emergency Department?

Introduction:

Drug-seeking behavior (DSB) in the emergency department (ED) is a very common problem, yet there has been little quantitative study to date of such behavior. The goal of this study was to assess the frequency with which drug seeking patients in the ED use classic drug seeking behaviors to obtain prescription medication.

Methods:

We performed a retrospective chart review on patients in an ED case management program for DSB. We reviewed all visits by patients in the program that occurred during a 1-year period, and recorded the frequency of the following behaviors: complaining of headache, complaining of back pain, complaining of dental pain, requesting medication by name, requesting a refill of medication, reporting medications as having been lost or stolen, reporting 10/10 pain, reporting greater than 10/10 pain, reporting being out of medication, and requesting medication parenterally. These behaviors were chosen because they are described as “classic” for DSB in the existing literature.

Results:

We studied 178 patients from the case management program, who made 2,486 visits in 1 year. The frequency of each behavior was: headache 21.7%, back pain 20.8%, dental pain 1.8%, medication by name 15.2%, requesting refill 7.0%, lost or stolen medication 0.6%, pain 10/10 29.1%, pain greater than 10/10 1.8%, out of medication 9.5%, and requesting parenteral medication 4.3%. Patients averaged 1.1 behaviors per visit.

Conclusion:

Drug-seeking patients appear to exhibit “classically” described drug-seeking behaviors with only low to moderate frequency. Reliance on historical features may be inadequate when trying to assess whether or not a patient is drug-seeking.

Association of pain score documentation and analgesic use in a pediatric emergency department

OBJECTIVES

This study characterizes the association between pain score documentation and analgesic administration among pediatric emergency department patients.

METHODS

This is a secondary analysis of a prospectively collected research database from an academic emergency department. Records of randomly sampled pediatric patients seen between August 2005 and October 2006 were reviewed. Pain scores from age-appropriate 0 to 10 numeric pain rating scales were abstracted (≥ 7 considered severe). Descriptive statistics and 95% confidence intervals (CIs) were calculated.

RESULTS

An initial pain score was documented in 87.4% of 4514 patients enrolled, 797 (17.7%) with severe pain. Of these, 63.1% (95% CI, 59.7%-66.5%) received an analgesic, and 16.7% (95% CI, 14.2%-19.5%) received it parenterally. Initial pain score documentation was similar across age groups. Patients younger than 2 years with severe pain were less likely to receive analgesics compared with teenaged patients with severe pain (32.1%; 95% CI, 15.9%-52.3%) versus 67.6% (95% CI, 63.2%-71.7%). Of 502 patients with documented severe pain who received analgesic, 23.3% (95% CI, 19.7%-27.3%) had a second pain score documented within 2 hours of the first. Documentation of a second pain score was associated with the use of parenteral analgesic and a second dose of analgesic.

CONCLUSIONS

In this population, initial pain score documentation was common, but severe pain was frequently untreated, most often in the youngest patients. Documentation of a second pain score was not common but was associated with more aggressive pain management when it occurred. Further study is needed to investigate causation and to explore interventions that increase the likelihood of severe pain being treated.

Time of admission, gender and age: challenging factors in emergency renal colic - a preliminary study

BACKGROUND

Nephrolithiasis is a relatively common problem and a frequent Emergency Department (ED) diagnosis in patients who present with acute flank/abdominal pain. The pain management in these patients is often challenging.

OBJECTIVES

To investigate the most effective dose of morphine with the least side effects in emergency renal colic patients.

MATERIALS AND METHODS

150 renal colic patients who experienced a pain level of 4 or greater, based on visual analog scale (VAS) at admission time were included. Pain was scored on a 100 mm VAS (0 = no pain, 100 = the worst pain imagined). When patients arrived at ED, a physician would examine the patients and assessed initial pain score, then filled a questionnaire according to the patient information. Patients were assigned to receive 2.5 mg morphine sulfate intravenously. We monitored patients' visual analog scale (VAS), and adverse events at different time points (every 15 minutes) for 90 minutes. Additional doses of intravenous morphine (2.5 mg) were administered if the patient still had pain. (Max dose: 10 mg). The cumulative dose of morphine, defined as the total amount of morphine prescribed to each patient during the 90 minutes of the study, was recorded. Patients were not permitted to use any nonsteroidal anti-inflammatory drugs as coadjuvant analgesics during the study period. Subjects with inadequate pain relief at 90 minutes received rescue morphine and were excluded from the study. The primary end point in this study was pain relief at 90 minutes, defined as either VAS<40 or decrease of 50% or more as compared to the initial VAS. The secondary objective was to detect the occurrence of adverse effects at any time points in ED.

RESULTS

The studied patients consisted of 104 men and 46 women with the mean age of 43 ±14 years (range, 18 to 75 years). There was no statistically significant difference between the mean age and gender differences in pain response. Rescue analgesia at 30 minutes were given in 54.5% receiving morphine. The average time to painless was 35 minutes. But there were no statistically significant differences between the mean age and gender differences in pain response (P > 0.05). Older patients responded sooner to morphine than the young. Most of the patients had a pain score of 90 -100 (77.3 %) at the beginning that was reduced to 29.4% during the 30 minutes follow up. During the first hour, we found that 94.7% of the patients had no pain or significant pain reduction and only 2.1% of the patients still had pain.

CONCLUSIONS

We conclude that there were no significant differences among the gender, time of admission and side - effects in renal colic patients in response to morphine.

Older US emergency department patients are less likely to receive pain medication than younger patients: results from a national survey

STUDY OBJECTIVE

The purpose of this study is to determine whether older adults presenting to the emergency department (ED) with pain are less likely to receive pain medication than younger adults.

METHODS

Pain-related visits to US EDs were identified with reason-for-visit codes from 7 years (2003 to 2009) of the National Hospital Ambulatory Medical Care Survey. The primary outcome was the administration of an analgesic. The percentage of patients receiving analgesics in 4 age groups was adjusted for measured covariates, including pain severity.

RESULTS

Pain-related visits accounted for 88,031 (46.9%) ED visits by patients aged 18 years or older during the 7-year period. There were 7,585 pain-related ED visits by patients aged 75 years or older, representing an estimated 3.65 million US ED visits annually. In comparing survey-weighted unadjusted estimates, pain-related visits by patients aged 75 years or older were less likely than visits by patients aged 35 to 54 years to result in administration of an analgesic (49% versus 68.3%) or an opioid (34.8% versus 49.3%). Absolute differences in rates of analgesic and opioid administration persisted after adjustment for sex, race/ethnicity, pain severity, and other factors and multiple imputation of missing pain severity data, with visits by patients aged 75 years and older being 19.6% (95% confidence interval 17.8% to 21.4%) less likely than visits by patients aged 35 to 54 years to receive an analgesic and 14.6% (95% confidence interval 12.8% to 16.4%) less likely to receive an opioid.

CONCLUSION

Patients aged 75 years and older with pain-related ED visits are less likely to receive pain medication than patients aged 35 to 54 years.
