Improving triage accuracy through a modified nurse-administered emergency department assessment of chest pain score on patients with chest pain at triage (EDACT): A prospective observational study

BackgroundChest pain triage in our emergency department (ED) prioritize patients for consultation based on unstructured nursing gestalt. The Emergency Department Assessment of Chest Pain Score (EDACS) identifies patients at low-risk for major adverse cardiac events and may provide standardization for chest pain triage in ED.MethodsWe conducted a prospective observational study, including adult patients with chief complaint of chest pain who were self-conveyed. We aimed to evaluate the overall diagnostic performance of a modified EDACS in triaging these patients.ResultsData was collected over 6 weeks, with 284 patients included in the final analysis. Nursing gestalt had higher sensitivity (97.6%, 95% confidence interval [CI] 87.4% to 99.9% versus EDACS 45.2%, 95% CI 29.8% to 61.3%), while modified EDACS provided higher specificity (76.4%, 95% CI 70.6% to 81.6%, versus nursing gestalt 29.8%, 95% CI 24.1% to 35.9%). EDACS with electrocardiogram had significantly better area under the receiver operating characteristic curve statistic (0.712; 95% CI 0.631 to 0.793) than EDACS alone (0.608; 95% CI 0.528 to 0.689) and nursing gestalt (0.637; 95% CI 0.600 to 0.674) (p = 0.0324).ConclusionsFurther studies should explore if modified EDACS, together with nursing gestalt, can improve triage accuracy for ED patients with chest pain.     

cTnT与CK--MB在胸痛危险分层中的作用

目的评价心肌肌钙蛋白T(cTnT)与肌酸激酶同工酶-MB(CK-MB)蛋白量在胸痛危险分层中的作用。方法对所有病例进行12h床边动态监测，包括基线、4、8、12h的连续心律监测和12导联心电图(ECG)测试；与此同时分别于基线、4、8、12h对入选胸痛组的其中383例患者测定cTnT、CK-MB。结果383例CPU患者只有8例(2．1％)CK-MB阳性，39例cTnT阳性。cTnT状态与随访的结果表明，cTnT阳性明显早于CK-MB。89％cTnT阳性患者血管造影术显示发生冠状动脉疾病(CAD)及多支血管病。结论cTnT比CK-MB在评估伴心肌坏死和多支血管病的胸痛危险分层中具有更高的敏感性与特异性；常规测定cTnT更便于胸痛的危险分层与处理。     

Exploring the attitudes & practices of shared decision-making for CT scan use in emergency department patients with abdominal pain

Background

Shared decision-making (SDM) has been studied in the emergency department (ED) in relation to hospital admissions but not for CT scan utilization. CT scans are a common imaging modality with high accuracy that emit considerable ionizing radiation. This study has three aims: to measure provider and patient preference for SDM; to evaluate patient involvement in the decision to order a CT scan; and to determine the association between patient involvement and CT utilization.

Integrating heart rate variability,vital signs,electrocardiogram, and troponin to triage chest pain patients in the ED

Background

Current triage methods for chest pain patients typically utilize symptoms, electrocardiogram (ECG), and vital sign data, requiring interpretation by dedicated triage clinicians. In contrast, we aimed to create a quickly obtainable model integrating the objective parameters of heart rate variability (HRV), troponin, ECG, and vital signs to improve accuracy and efficiency of triage for chest pain patients in the emergency department (ED).

Children's participation in shared decision-making: Children,adolescents, parents and healthcare professionals' perspectives and experiences

Purpose of the researchDespite decision-making featuring throughout the trajectory of cancer care, children's participation in decision-making remains an area much under-researched and complicated by conflicting opinions. This study explored children's participation in shared decision-making (SDM) from multiple perspectives from one haematology/oncology unit in Ireland.Methods and sampleQualitative research design was used to explore participants' experiences of children's decision-making. Interviews were conducted with children¹ aged 7–16 years (n = 20), their parents (n = 22) and healthcare professionals (n = 40). Data were managed with the aid of NVivo (version 8).Key resultsParents and children's roles in decision-making were significantly influenced by the seriousness of the illness. Cancer is a life-threatening illness and so the treatment ‘had to be done’. Children were not involved in major decisions (treatment decisions) as refusal was not an option. They were generally involved in minor decisions (choices about care delivery) with the purpose of gaining their cooperation, making treatment more palatable, giving back a sense of control and building trusting relationships. These choices were termed ‘small’ decisions that would not compromise the child's welfare. Some adolescents were aware that choices were not ‘real’ decisions since they were not allowed to refuse and expressed feelings of frustration.ConclusionsHealthcare professionals and parents controlled the process of SDM and the children's accounts revealed that they held a minimal role. Children appeared content that adults held responsibility for the major treatment decisions. However, they desired and valued receiving information, voicing their preferences and choosing how treatments were administered to them.     

HEARTS3对提高急诊非ST段抬高胸痛危险分层作用的研究

目的 在HEART评分系统基础上,研究HEARTS3评分对提高急诊非ST段抬高胸痛患者危险分层和急性冠脉综合征(ACS)的预测应用价值.方法 回顾性分析2011年7月至2015年5月775例符合标准的急诊非ST段抬高胸痛患者,分别进行HEART和HEARTS3评分,并随访患者发病后30 d内ACS和心肌梗死(MI)发病情况,根据评分进行危险分层,分析不同分层患者发病后30 dACS与MI的发生情况与评分之间的关系,并比较两种评分对胸痛患者发病后30 d ACS的预测能力.使用SPSS 13.0软件进行统计分析计数资料以百分比(％)表示,两组计量资料之间的比较用成组t检验,两种评分不同评分段患者发生ACS比例比较用行x列表x2检验,每种评分方法对发生心血管事件ACS患者分辨度用ROC曲线下面积(AUROC),并用Z检验进行比较.结果 共有92例发病后30 d发生ACS,HEART和HEARTS3的对高危胸痛患者预测敏感性分别为64.79％、77.97％,特异性分别为97.57％、97.85％.HEART与HEARTS3危险评分ROC曲线下面积,MI(0.952 vs.0.813;P =0.028),30 dACS (0.913 vs.0.815;P=0.034),两者差异具有统计学意义.结论 HEART和HEARTS3都可以应用于急诊胸痛患者的危险分层和预后评估,但HEARTS3更可靠.     

Performance of HEART and TIMI scores in predicting major adverse cardiovascular events (MACEs) of chest pain patients in the emergency department: A prospective observational study

Objective: To compare the value of HEART and TIMI scores in predicting major adverse cardiovascular events (MACEs) of patients with chest pain in the emergency department at a tertiary care hospital in Ahmedabad, a city in western India. Methods: A prospective study was conducted on chest pain patients from January to December 2019. All adult patients with non-traumatic chest pain presenting to the emergency department were included, and their HEART and TIMI scores were evaluated. The patients were followed up within 4 weeks for monitoring any major adverse cardiac events or death. The receiver-operating characteristics (ROC) curve was used to determine the value of HEART and TIMI scores in predicting MACEs. Besides, the specificity, sensitivity, positive predictive value (PPV), and negative predictive value (NPV) of the two scores were assessed and compared. Results: A total of 350 patients were evaluated [mean age (55.03±16.6) years, 56.6％ of males]. HEART score had the highest predictive value of MACEs with an area under the curve (AUC) of 0.98, followed by the TIMI score with an AUC of 0.92. HEART score had the highest specificity of 98.0％ (95％ CI: 96.4％-99.6％), the sensitivity of 75.0％ (95％ CI: 70.7％-79.3％), and PPV of 97.0％ (95％ CI: 94.1％-99.9％) and NPV of 82.5％ (95％ CI: 74.6％-90.4％) for low-risk patients. TIMI score had a specificity of 95.0％ (95％ CI: 92.4％-97.6％), sensitivity of 75.0％ (95％ CI: 69.4％-80.6％), PPV of 92.3％ (95％ CI: 88.1％-96.5％) and NPV of 82.3％ (95％ CI: 73.8％-90.8％) for low-risk patients. Conclusions: HEART score is an easier and more practical triage instrument to identify chest pain patients with low-risk for MACEs compared to TIMI score. Patients with high HEART scores have a higher risk of MACEs and require early therapeutic intervention and aggressive management.     

The clinical utility of the pain assessment tool in ventilated,sedated, and muscle-relaxed neonates

BackgroundThe neonatal Pain Assessment Tool (PAT) is considered a reliable and valid tool for assessing neonatal pain. No research has been conducted on the clinical utility of the PAT when assessing pain in ventilated, sedated, and muscle-relaxed neonates.ObjectiveThe objective of the study was to determine the clinical utility of the PAT when assessing pain in ventilated, sedated, and muscle-relaxed neonates.MethodsNeonatal nurses from the Royal Children's Hospital completed online surveys to assess the clinical utility of the PAT. Three focus groups were then conducted to further explore the variation of pain scores from the survey and clarify the challenges in interpreting the pain score.ResultsNurses perceived the PAT clinically useful in neonates who were ventilated and minimally sedated. However, the PAT was not clinically useful in neonates who were ventilated and heavily sedated or muscle-relaxed. Further exploration via focus groups highlighted two themes related to the ‘variation in the timing of the pain score’ and the ‘integration of critical thinking and judgement’ used when assessing pain in neonates.ConclusionsThe clinical utility of the PAT is acceptable for minimally sedated neonates; however, it decreases the more sedated a neonate becomes, and the PAT's usefulness is extremely poor in the muscle-relaxed neonate. A better understanding of the timing and interpretation of the pain score in relation to the neonate's clinical status may enable improved decision-making and pain management. The PAT requires further validity, reliability, and clinical utility research, particularly in critically ill and muscle-relaxed neonates.     

Practicality, safety and accuracy of computed tomography coronary angiography in the evaluation of low TIMI-risk score chest pain patients: a pilot study

Objectives: The present pilot study aimed to assess the practicality, safety and accuracy of performing CT coronary angiography (CT‐CA) in the evaluation of acute chest pain of patients with low thrombolysis in myocardial infarction (TIMI) risk scores. Methods: The present prospective observational study was undertaken in a university teaching hospital between November 2004 and December 2005. Participants were a convenience sample of patients admitted to hospital for investigation of chest pain with TIMI risk scores <3. Consenting patients underwent CT‐CA within 48 h of presentation. Outcomes of interest were practicality (proportion of diagnostic quality scans obtained and preparation time for CT‐CA), rate of serious adverse events, and accuracy at the patient level using selective coronary angiography as the reference standard. Results: Thirty‐four patients were recruited. Diagnostic quality scans were obtained in 26/34 or 76% of patients (four failed CT‐CA and four non‐diagnostic scans). The median CT preparation time was 1.9 h (range 0.17–4.0). No serious adverse events were found. Fourteen of those 26 patients with diagnostic CT‐CA subsequently had selective coronary angiography, of which nine were positive. The sensitivity and specificity of CT‐CA in identifying patients with significant coronary artery disease were 9/9 (100%; 95% confidence interval 72–100%) and 4/5 (80%; 95% confidence interval 28–100%), respectively. Conclusions: The majority of acute chest pain patients with low TIMI risk scores were successfully scanned with a 16‐slice CT to produce CT‐CA studies with good diagnostic quality and accuracy. No major adverse events were found. The place of CT‐CA in diagnostic workup for chest pain remains to be defined.     

The effect of venlafaxine on ongoing and experimentally induced pain in neuropathic pain patients: a double blind, placebo controlled study.

BACKGROUND AND AIM: The aim of this randomized double blind placebo controlled study was to investigate the effectiveness and the safety of venlafaxine XR 75 and 150 mg on ongoing pain and on quantitative sensory tests in 60 patients with neuropathic pain for 8 weeks. METHODS: Evaluation parameters consisted of ongoing pain intensity (VAS), patient satisfaction, side effects, global efficacy and tolerance. Quantitative sensory measurements taken from the affected area before and after the drug treatment included pin-prick hyperalgesia, allodynia, detection and pain thresholds to electrical and heat stimuli, temporal summation of repetitive electrical and heat stimuli. RESULTS: A total of 55 patients completed the study. VAS scores decreased significantly compared to the baseline measurements in all groups. There was no significant difference between the groups regarding pain intensity and escape medication. The areas of allodynia and pin-prick hyperalgesia decreased significantly in venlafaxine groups compared to the placebo. There was no significant difference between the groups regarding the detection thresholds (electrical and heat). The pain threshold and the summation threshold to electrical stimuli and the summation threshold to heat stimuli increased significantly following treatment in both venlafaxine groups. In addition, the degree of the temporal summation to electrical and heat stimuli decreased significantly following treatment in both venlafaxine groups compared to the placebo. CONCLUSION: The study showed significant effect of venlafaxine in the manifestations of hyperalgesia and temporal summation, but not on the ongoing pain intensity. Furthermore, the quantitative sensory tests provided complementing information to the clinical measures.     

Attempting to solve the problem of pain: a questionnaire study in acute and chronic pain patients

When faced with the problem of pain one can attempt a solution aimed at relief (assimilation) or a solution aimed at acceptance (accommodation). Using this dual process model of adaptation to pain, this study compares acute and chronic pain patients on their approach to problem solving. Three hundred and sixty-four patients were recruited from clinical settings, 303 with chronic pain and 61 with acute pain, and completed a range of measures of both affect and pain-related behavior, including the Pain Solutions Questionnaire. The effects of overall duration of pain were also investigated. Chronic pain patients reported greater disability and catastrophic thinking about pain than acute pain patients, and assimilative coping was associated with greater disability, greater attention to pain, and more catastrophic thinking about pain, beyond the effects of demographic variables and pain severity. Pain duration did not moderate these associations. Only in the case of catastrophic thinking about pain was it found that the effects of assimilative coping were moderated by pain duration. For chronic pain patients, catastrophic thinking about pain was greater when assimilative coping was higher. These results are discussed within the context of a goal directed motivational model of adaptation to chronic pain.     

Anxiety and depressive disorders in patients presenting with chest pain to the emergency department: a comparison between cardiac and non-cardiac origin

Objective: The aim of this study was to determine the prevalence of anxiety and depressive disorders in patients presenting with chest pain to the Emergency Department (ED) and determine if there is a relationship between these and cardiac vs. non-cardiac chest pain. Methods: This prospective cross-sectional study was performed in an urban tertiary care hospital between March and October 2005. Consecutive patients presenting with chest pain were enrolled in the study. The prevalence of anxiety and depressive disorders in patients with chest pain were determined by using the Hospital Anxiety and Depression Scale. Results: A total of 324 patients presented to the ED with chest pain during the study period. The mean age of the patients studied was 50.5 ± 14 years; 67% were men and 33% were women. Of the 324 study patients, 194 (59.9%) patients were diagnosed with non-cardiac chest pain, 16 (4.9%) with stable angina, 84 (25.9%) with unstable angina, and 30 (9.3%) with acute myocardial infarction. No statistically significant differences were determined between patients with cardiac and non-cardiac chest pain both for anxiety (40% vs. 38.1%, respectively; p = 0.737) and depressive disorders (52.3% vs. 52.1%, respectively; p = 0.965). Conclusion: Anxiety and depressive disorders are common among patients presenting with chest pain to the ED. However, the prevalence of anxiety and depressive disorders is similar between patients with chest pain of cardiac and non-cardiac origin. Chest pain should not be attributed to an anxiety or depressive disorder before organic etiologies are excluded.     

The prognostic value of sepsis scores and dichotomized triage score in patients presenting to the emergency department with fever: A prospective,observational study

BackgroundThe performance of the Quick Sequential Organ Failure Assessment (qSOFA) score needs to be explored further in the emergency triage room. This study aims to explore the performance of triage (tqSOFA) versus the dichotomized triage score (DTS) in patients admitted to the emergency room triage with fever.MethodsThis research was designed as a prospective, observational study within a six-month period, including patients who presented to the emergency room triage with infrared fever ≥ 37.5 °C.Results771 patients were analyzed.The highest sensitivity for predicting overall hospitalization and intensive care admission was seen for DTS (95.4 %, 100 %; p < 0.0001, p < 0.0001, respectively) (AUC:0.697, 95 % CI 0.663 to 0.730; AUC:0.684, 95 % CI 0.650 to 0.717, respectively). The highest sensitivity for predicting 1st week and 1st month mortality was found for DTS (100 %, 96.3 %; p < 0.0001, p < 0.0001, respectively). However, the highest specificity for predicting 1st week and 1st month mortality was observed in tqSOFA (94.1 %, 95.16; p = 0.0845, p < 0.0001, respectively) (AUC:0.658, 95 % CI 0.623 to 0.691; AUC:0.698, 95 % CI 0.664 to 0.730, respectively).ConclusionWe found DTS to be as effective as tqSOFA and SIRS in determining all hospitalization times and mortality.     

Demographic and medical parameters in the development of complex regional pain syndrome type 1 (CRPS1): prospective study on 596 patients with a fracture

Limited data are available on the incidence of complex regional pain syndrome type 1 (CRPS1) and on demographic and medical risk factors for the development of CRPS1. The objective of this study was to investigate the incidence of CRPS1 in patients with a fracture using 3 sets of diagnostic criteria and to evaluate the association between demographic/medical factors and the development of CRPS1 diagnosed with the Harden and Bruehl criteria. A prospective multicenter cohort study of 596 patients (ages 18 years and older) with a single fracture of the wrist, scaphoid, ankle, or metatarsal V, recruited patients from the emergency rooms of 3 Dutch hospitals. Of the 596 participants, 42 (7.0%) were diagnosed with CRPS1 according to the Harden and Bruehl criteria, 289 (48.5%) according to the International Association for the Study of Pain criteria, and 127 (21.3%) according to the criteria of Veldman. An analysis of the medical and demographic differences revealed that patients in whom CRPS1 later developed more often had intra-articular fractures, fracture dislocations, rheumatoid arthritis, or musculoskeletal comorbidities. An ankle fracture, dislocation, and an intra-articular fracture contributed significantly to the prediction of the development of CRPS1. No CRPS1 patients were symptom free at 12 months (T3). At baseline, patients with CRPS1 had significantly more pain than patients without CRPS1 (P<.001). The incidence of the diagnosis of CRPS1 after a single fracture depends to a large extent on the diagnostic criteria used. After a fracture, 7% of the patients developed CRPS1 and none of the patients were free of symptoms at 1-year follow-up.     

Short-term effectiveness of an intervention targeting lower limb range of motion on pain and disability in patellofemoral pain patients: A randomized,non-concurrent multiple-baseline study

IntroductionPatellofemoral pain (PFP) is a common and often long-standing musculoskeletal condition. Evidence of the effectiveness of interventions addressing soft tissue flexibility is conflicting and of inconsistent scientific quality. However, reduced soft tissue flexibility can negatively affect patellofemoral joint kinematics. Lower limb range of motion (LLROM) reflects soft tissue flexibility throughout the kinetic chain. The aim was to evaluate the short-term effectiveness of an intervention targeting LLROM on pain and disability in patients with PFP.MethodsA randomized, non-concurrent, multiple-baseline single-case design with a two-week intervention phase and baseline and postintervention phase with varying length was conducted. Eight participants (5 females, 3 males) of age 19(±1.6) years, weekly sports participation 12(±3.1) hours and 17(±14) months symptom duration were included. The Anterior Knee Pain Scale – Dutch Version (AKPS-DV) and the Patient Specific Complaint Scale (PSCS) were administered twice a week. After allocating participants to one of four subgroups of reduced LLROM the intervention was applied. The intervention consisted of soft tissue techniques (mobilization, taping, and stretching).ResultsParticipant 3 and 6 showed a medium and small but statistically significant positive effect on the AKPS-DV. Participant 2 showed a large and statistically significant positive effect on the PSCS.ConclusionsThis study provides moderate evidence that an intervention targeting LLROM in patients with PFP reduces pain and disability in the short-term. Further research is needed to evaluate the long-term effectiveness and optimize individual treatment outcomes.
