Mindfulness-based intervention in patients with persistent pain in chest (MIPIC) of non-cardiac cause: a feasibility randomised control study.

OBJECTIVE: The study evaluated the feasibility of mindfulness-based cognitive therapy (MBCT) in patients with non-cardiac chest pain by assessing their willingness to participate and adhere to the programme, and for these data to help further refine the content of MBCT for chest pain. PATIENTS AND METHODS: This prospective 2:1 randomised controlled trial compared the intervention of adapted MBCT as an addition to usual care with just usual care in controls. Among 573 patients who attended the rapid access chest pain clinic over the previous 12 months and were not diagnosed with a cardiac cause but had persistent chest pain were invited. The intervention was a 2-hour, weekly, online guided 8-week MBCT course. Compliance with attendance and the home practice was recorded. Enrolled patients completed the Seattle angina questionnaire (SAQ), Hospital Anxiety and Depression Scale, Cardiac Anxiety Questionnaire, Five-Facet Mindfulness Questionnaire, and Euro Quality of Life-5 Dimensions-5 Level at baseline assessment and after 8-week period. RESULTS: Persistent chest pain was reported by 114 patients. Of these, 33 (29%) patients with a mean age of 54.2 (±12.2) years and 68% women, consented to the study. Baseline questionnaires revealed mild physical limitation (mean SAQ, 76.8±25), high levels of anxiety (76%) and depression (53%), modest cardiac anxiety (CAQ,1.78±0.61) and mindfulness score (FFMQ, 45.5±7.3). Six patients subsequently withdrew due to bereavement, caring responsibilities and ill health. Of the remaining 27 participants, 18 in the intervention arm attended an average of 5 sessions with 61% attending ≥6 sessions. Although not statistically powered, the study revealed a significant reduction in general anxiety, improved mindfulness and a trend towards improvement in SAQ scores in the intervention arm. CONCLUSION: One-third of patients with persistent non-cardiac chest pain were willing to participate in mindfulness-based therapy. An improvement in anxiety and mindfulness was detected in this feasibility study. A larger trial is required to demonstrate improvement in chest pain symptoms.

Higher intensity of 72-h noninvasive cardiac test referral does not improve short-term outcomes among emergency department patients with chest pain.

BACKGROUND: It is unclear whether referral for cardiac noninvasive testing (NIT) following emergency department (ED) chest pain encounters improves short-term outcomes. METHODS: This was a retrospective cohort study of patients presenting with chest pain, without ST-elevation myocardial infarction or myocardial injury by serum troponin testing, between 2013 and 2019 to 21 EDs within an integrated health care system. We examined the association between NIT referral (within 72 h of the ED encounter) and a primary outcome of 60-day major adverse cardiac events (MACE). Secondary outcomes were 60-day MACE without coronary revascularization (MACE-CR) and 60-day all-cause mortality. To account for confounding by indication for NIT, we grouped patient encounters into ranked tertiles of NIT referral intensity based on the likelihood of 72-h NIT referral associated with the initially assigned emergency physician, relative to local peers and within discrete time periods. Associations between NIT referral-intensity tertile and outcomes were assessed using risk-adjusted multivariable logistic regression. RESULTS: Among 210,948 eligible patient encounters, 72-h NIT referral frequency was 11.9%, 18.3%, and 25.9% in low, intermediate, and high NIT referral-intensity encounters, respectively. Compared with the low referral-intensity tertile, there was a higher risk of 60-day MACE within the high referral-intensity tertile (odds ratio [OR] = 1.11, 95% confidence interval [CI] = 1.04 to 1.17) due to more coronary revascularizations without corresponding differences in MACE-CR or all-cause mortality. In analyses stratified by patients' estimated risk (HEART score; 50.5% lower risk, 38.7% moderate risk, 10.8% higher risk), the difference in 60-day MACE was primarily attributable to moderate-risk encounters (OR = 1.15, 95% CI = 1.08 to 1.24), with no differences among either lower- (OR = 1.10, 95% CI = 0.92 to 1.31) or higher- (OR = 1.01, 95% CI = 0.90 to 1.14) risk encounters. CONCLUSION: Higher referral intensity for 72-h NIT was associated with higher risk of coronary revascularization but no difference in adverse events within 60 days. These findings further call into question the urgency of NIT among ED patients without objective evidence of myocardial injury.

Graded Coronary Risk Stratification for Emergency Department Patients With Chest Pain: A Controlled Cohort Study.

Background Resource utilization among emergency department (ED) patients with possible coronary chest pain is highly variable. Methods and Results Controlled cohort study amongst 21 EDs of an integrated healthcare system examining the implementation of a graded coronary risk stratification algorithm (RISTRA-ACS [risk stratification for acute coronary syndrome]). Thirteen EDs had access to RISTRA-ACS within the electronic health record (RISTRA sites) beginning in month 24 of a 48-month study period (January 2016 to December 2019); the remaining 8 EDs served as contemporaneous controls. Study participants had a chief complaint of chest pain and serum troponin measurement in the ED. The primary outcome was index visit resource utilization (observation unit or hospital admission, or 7-day objective cardiac testing). Secondary outcomes were 30-day objective cardiac testing, 60-day major adverse cardiac events (MACE), and 60-day MACE-CR (MACE excluding coronary revascularization). Difference-in-differences analyses controlled for secular trends with stratification by estimated risk and adjustment for risk factors, ED physician and facility. A total of 154 914 encounters were included. Relative to control sites, 30-day objective cardiac testing decreased at RISTRA sites among patients with low (≤2%) estimated 60-day MACE risk (-2.5%, 95% CI -3.7 to -1.2%, P<0.001) and increased among patients with non-low (>2%) estimated risk (+2.8%, 95% CI +0.6 to +4.9%, P=0.014), without significant overall change (-1.0%, 95% CI -2.1 to 0.1%, P=0.079). There were no statistically significant differences in index visit resource utilization, 60-day MACE or 60-day MACE-CR. Conclusions Implementation of RISTRA-ACS was associated with better allocation of 30-day objective cardiac testing and no change in index visit resource utilization or 60-day MACE.

Prospective Validation and Comparative Analysis of Coronary Risk Stratification Strategies Among Emergency Department Patients With Chest Pain.

Background Coronary risk stratification is recommended for emergency department patients with chest pain. Many protocols are designed as "rule-out" binary classification strategies, while others use graded-risk stratification. The comparative performance of competing approaches at varying levels of risk tolerance has not been widely reported. Methods and Results This is a prospective cohort study of adult patients with chest pain presenting between January 2018 and December 2019 to 13 medical center emergency departments within an integrated healthcare delivery system. Using an electronic clinical decision support interface, we externally validated and assessed the net benefit (at varying risk thresholds) of several coronary risk scores (History, ECG, Age, Risk Factors, and Troponin [HEART] score, HEART pathway, Emergency Department Assessment of Chest Pain Score Accelerated Diagnostic Protocol), troponin-only strategies (fourth-generation assay), unstructured physician gestalt, and a novel risk algorithm (RISTRA-ACS). The primary outcome was 60-day major adverse cardiac event defined as myocardial infarction, cardiac arrest, cardiogenic shock, coronary revascularization, or all-cause mortality. There were 13 192 patient encounters included with a 60-day major adverse cardiac event incidence of 3.7%. RISTRA-ACS and HEART pathway had the lowest negative likelihood ratios (0.06, 95% CI, 0.03-0.10 and 0.07, 95% CI, 0.04-0.11, respectively) and the greatest net benefit across a range of low-risk thresholds. RISTRA-ACS demonstrated the highest discrimination for 60-day major adverse cardiac event (area under the receiver operating characteristic curve 0.92, 95% CI, 0.91-0.94, P<0.0001). Conclusions RISTRA-ACS and HEART pathway were the optimal rule-out approaches, while RISTRA-ACS was the best-performing graded-risk approach. RISTRA-ACS offers promise as a versatile single approach to emergency department coronary risk stratification. Registration URL: https://www.clinicaltrials.gov; Unique identifier: NCT03286179.

The Changing Role of Chest Pain in the Emergency Department Observation Unit.

BACKGROUND: This study objective was to describe changes in the utilization of a protocol-driven emergency department observation unit (EDOU) for chest pain over time. METHODS: This is a retrospective serial cross-sectional study of data from a clinical data warehouse of a single integrated healthcare system. We estimated long-term trends (2009-2019) in EDOU visits at 4 system hospitals, using monthly proportions as the main outcome, and month of visit as the exposure variable, accounting for age and sex. Rate changes associated with compulsory use of the History, EKG, Age, Risk factors, Troponin (HEART) score in 2016 were analyzed. RESULTS: There were 83,168 EDOU admissions among 1.3 million ED visits during the study interval, with an average admission rate of 5.9% of ED visits. The most common conditions were chest pain (41.2%), transient ischemic attack (7.8%), dehydration (6.3%), syncope (5.8%), and abdominal pain (5.2%). In each hospital, there was a temporal annual decline in the proportion of EDOU visits for chest pain protocols ranging from -7.9% to -2.8%, an average rate of -3.3% per year (95% CI, -4.6% to -2.0%) or a 54% (from 54% to 25%) relative decline in over the 11-year study interval. This decline was significantly steeper in younger middle-aged patients (ages 39-49). The HEART score intervention had a small impact on baseline decline of -3.1% at the 2 intervention hospitals, reducing it by -1.5% (95% CI, -2.2% to -0.8%). CONCLUSIONS: Utilization of the EDOU for chest pain decreased over time, with corresponding increases in other conditions. This decline preceded the introduction of the HEART score.

Higher Emergency Physician Chest Pain Hospitalization Rates Do Not Lead to Improved Patient Outcomes.

BACKGROUND: Wide variation exists for hospital admission rates for the evaluation of possible acute coronary syndrome, but there are limited data on physician-level variation. Our aim is to describe physicians' rates of admission for suspected acute coronary syndrome and associated 30-day major adverse events. METHODS: We conducted a retrospective analysis of adult emergency department chest pain encounters from January 2016 to December 2017 across 15 community emergency departments within an integrated health system in Southern California. The unit of analysis was the Emergency physician. The primary outcome was the proportion of patients admitted/observed in the hospital. Secondary analysis described the 30-day incidence of death or acute myocardial infarction. RESULTS: Thirty-eight thousand seven hundred seventy-eight patients encounters were included among 327 managing physicians. The median number of encounters per physician was 123 (interquartile range, 82-157) with an overall admission/observation rate of 14.0%. Wide variation in individual physician admission rates were observed (unadjusted, 1.5%-68.9%) and persisted after case-mix adjustments (adjusted, 5.5%-27.8%). More clinical experience was associated with a higher likelihood of hospital care. There was no difference in 30-day death or acute myocardial infarction between high- and low-admitting physician quartiles (unadjusted, 1.70% versus 0.82% and adjusted, 1.33% versus 1.29%). CONCLUSIONS: Wide variation persists in physician-level admission rates for emergency department chest pain evaluation, even in a well-integrated health system. There was no associated benefit in 30-day death or acute myocardial infarction for patients evaluated by high-admitting physicians. This suggests an additional opportunity to investigate the safe reduction of physician-level variation in the use of hospital care.

Missed acute myocardial infarction in the emergency department-standardizing measurement of misdiagnosis-related harms using the SPADE method.

OBJECTIVES: Diagnostic error is a serious public health problem. Measuring diagnostic performance remains elusive. We sought to measure misdiagnosis-related harms following missed acute myocardial infarctions (AMI) in the emergency department (ED) using the symptom-disease pair analysis of diagnostic error (SPADE) method. METHODS: Retrospective administrative data analysis (2009-2017) from a single, integrated health system using International Classification of Diseases (ICD) coded discharge diagnoses. We looked back 30 days from AMI hospitalizations for antecedent ED treat-and-release visits to identify symptoms linked to probable missed AMI (observed > expected). We then looked forward from these ED discharge diagnoses to identify symptom-disease pair misdiagnosis-related harms (AMI hospitalizations within 30-days, representing diagnostic adverse events). RESULTS: A total of 44,473 AMI hospitalizations were associated with 2,874 treat-and-release ED visits in the prior 30 days. The top plausibly-related ED discharge diagnoses were "chest pain" and "dyspnea" with excess treat-and-release visit rates of 9.8% (95% CI 8.5-11.2%) and 3.4% (95% CI 2.7-4.2%), respectively. These represented 574 probable missed AMIs resulting in hospitalization (adverse event rate per AMI 1.3%, 95% CI 1.2-1.4%). Looking forward, 325,088 chest pain or dyspnea ED discharges were followed by 508 AMI hospitalizations (adverse event rate per symptom discharge 0.2%, 95% CI 0.1-0.2%). CONCLUSIONS: The SPADE method precisely quantifies misdiagnosis-related harms from missed AMIs using administrative data. This approach could facilitate future assessment of diagnostic performance across health systems. These results correspond to ∼10,000 potentially-preventable harms annually in the US. However, relatively low error and adverse event rates may pose challenges to reducing harms for this ED symptom-disease pair.

60-day major adverse cardiac events in emergency department patients with non-low modified HEART scores.

BACKGROUND: A low (0-3) History, Electrocardiogram, Age, Risk factors and Troponin (HEART) score reliably identifies ED chest pain patients who are low risk for near-term major adverse cardiac events (MACE). To optimize sensitivity, many clinicians employ a modified HEART score by repeating troponin measurements and excluding patients with abnormal troponin values or ischemic electrocardiograms (ECGs). The residual MACE risk among patients with otherwise non-low (≥4) modified HEART scores is thus likely much lower than with non-low original HEART scores. OBJECTIVE: To explore residual 60-day MACE risks among patients with non-low modified HEART scores. METHODS: Secondary analysis of a retrospective cohort of ED patients presenting with chest pain to an integrated healthcare system between 2013 and 2015. Patients with serial troponin measurements within 6 h of ED arrival were considered for inclusion. Exclusions included an ischemic ECG, troponin values above the 99th percentile or a lack of continuous health plan coverage through the 60-day follow-up period. MACE was defined as a composite of myocardial infarction, cardiac arrest, cardiogenic shock or death. RESULTS: There were 22,976 study eligible patients encounters, 13,521 (59%) of which had non-low (≥4) modified HEART scores. The observed 60-day MACE risk among non-low HEART score patients was 2.0% (95% CI 1.8-2.3). When including all coronary revascularizations (MACE-R), the risk was 4.4% (95% CI 4.1-4.4). CONCLUSION: Risk of near-term MACE among patients with non-low modified HEART scores (excluding those with abnormal troponin or ischemic ECGs) appears to be much lower than in the original HEART score validation studies.

Automated Retrospective Calculation of the EDACS and HEART Scores in a Multicenter Prospective Cohort of Emergency Department Chest Pain Patients.

OBJECTIVES: Coronary risk scores are commonly applied to emergency department patients with undifferentiated chest pain. Two prominent risk score-based protocols are the Emergency Department Assessment of Chest pain Score Accelerated Diagnostic Protocol (EDACS-ADP) and the History, ECG, Age, Risk factors, and Troponin (HEART) pathway. Since prospective documentation of these risk determinations can be challenging to obtain, quality improvement projects could benefit from automated retrospective risk score classification methodologies. METHODS: EDACS-ADP and HEART pathway data elements were prospectively collected using a Web-based electronic clinical decision support (eCDS) tool over a 24-month period (2018-2019) among patients presenting with chest pain to 13 EDs within an integrated health system. Data elements were also extracted and processed electronically (retrospectively) from the electronic health record (EHR) for the same patients. The primary outcome was agreement between the prospective/eCDS and retrospective/EHR data sets on dichotomous risk protocol classification, as assessed by kappa statistics (ĸ). RESULTS: There were 12,110 eligible eCDS uses during the study period, of which 66 and 47% were low-risk encounters by EDACS-ADP and HEART pathway, respectively. Agreement on low-risk status was acceptable for EDACS-ADP (ĸ = 0.73, 95% confidence interval [CI] = 0.72 to 0.75) and HEART pathway (ĸ = 0.69, 95% CI = 0.68 to 0.70) and for the continuous scores (interclass correlation coefficients = 0.87 and 0.84 for EDACS and HEART, respectively). CONCLUSIONS: Automated retrospective determination of low risk status by either the EDACS-ADP or the HEART pathway provides acceptable agreement compared to prospective score calculations, providing a feasible risk adjustment option for use in large data set analyses.

Elevated D-Dimer Combined with Persistent Acupuncture-like Chest Pain in An Elderly Patient Misdiagnosed as Pulmonary Embolism Finally Proved as Lung Hamartoma with Secondary Lung Infection by Bronchoscopy Biopsy: a Case Report and Literature Review.

BACKGROUND: Pulmonary hamartoma is one of the most common benign tumors of the lung, the symptoms are often atypical, so its diagnosis is not so easy. We presented an elderly man with elevated D-dimer combined persistent acupuncture-like chest pain misdiagnosed as pulmonary embolism finally proved as lung hamartoma with secondary lung infection by bronchoscopy biopsy. METHODS: Appropriate laboratory tests were carried out. The chest computed tomography (CT) scan and bronchoscopy were performed for diagnosis. RESULTS: Laboratory tests showed D-dimer was 2,615.88 ng/mL, the chest CT scan showed the right lung portal occupying lesions accompanied by obstructive changes in the middle of the right lung and mediastinal lymphade-nopathy with partial calcification. Bronchoscopy showed the new spherical neoplasm in the middle of the right lung completely blocked the opening of the bronchus, the surface of the neoplasm was smooth and blood vessels were abundant, pathological result was lung hamartoma. CONCLUSIONS: Elevated D-dimer is not a specific index of pulmonary embolism. When a patient's D-dimer rise combined with severe chest pain, the physician should be wary of pulmonary embolism, myocardial infarction, aortic dissection, and other emergencies, and should also take into account serious infections, tumors, and other diseases. Diagnosis needs further related examination. Chest CT scan has guidance function, and when the chest CT scan suggests the occupying lesion, the pathology examination is the key to identify the benign tumor.

A 60-Year-Old Woman With Acute Chest Pain and Bilateral Pleural and Pericardial Effusions.

CASE PRESENTATION: A 60-year-old woman presented with acute-onset, progressively worsening shortness of breath and pleuritic chest pain for 3 days. She also complained of a dry cough, but no fever or chills. There was no history of swelling of the feet; nor was there a history of nausea or diarrhea. She was a lifelong nonsmoker and had no history of recent travel or sick contacts. Her medical history included hypertension and ulcerative colitis. The ulcerative colitis was in remission and she had not been taking medications for this for over 7 years. Her home medications included alendronate, amlodipine, aspirin, atenolol, and vitamin D3 supplements. She had no allergies.

Emergency Department Clinician Experiences and Perceptions Regarding Noncardiac Chest Pain: A Cross-Sectional Survey. / Emergency Department Clinician Experiences and Perceptions Regarding Noncardiac Chest Pain: A Cross-Sectional Survey.

OBJECTIVES: The objectives of this study are to report the responses of emergency department (ED) clinicians regarding the characteristics and management of patients with noncardiac chest pain (NCCP) and to explore clinician experiences with the current standard of care and whether nonpharmacologic or nonsurgical referral options would be considered. METHODS: A cross-sectional survey was delivered to 40 ED clinicians from hospitals in Winnipeg, Manitoba from 2012 to 2013. Data were reduced descriptively and thematically summarized to assess the characteristics of patients with NCCP along with the responses of ED clinicians regarding the management of NCCP. RESULTS: The survey response was 27 (67.5% response rate). They reported that patients with NCCP comprised a considerable amount of ED care and are a variable and heterogeneous population. Respondents agreed (63.0%) that onsite and on-call providers for NCCP referral would assist in patient management. Further, ED clinicians (66.7%) would consider referring patients with NCCP to a nonpharmacologic, nonsurgical clinical research study. CONCLUSION: Clinicians in this study wanted better access to on-site referrals and outpatient clinics for patients experiencing NCCP after discharge and would consider nonpharmacologic or nonsurgical referral.

Evaluation of Outpatient Cardiac Stress Testing After Emergency Department Encounters for Suspected Acute Coronary Syndrome.

STUDY OBJECTIVE: Professional guidelines recommend 72-hour cardiac stress testing after an emergency department (ED) evaluation for possible acute coronary syndrome. There are limited data on actual compliance rates and effect on patient outcomes. Our aim is to describe rates of completion of noninvasive cardiac stress testing and associated 30-day major adverse cardiac events. METHODS: We conducted a retrospective analysis of ED encounters from June 2015 to June 2017 across 13 community EDs within an integrated health system in Southern California. The study population included all adults with a chest pain diagnosis, troponin value, and discharge with an order for an outpatient cardiac stress test. The primary outcome was the proportion of patients who completed an outpatient stress test within the recommended 3 days, 4 to 30 days, or not at all. Secondary analysis described the 30-day incidence of major adverse cardiac events. RESULTS: During the study period, 24,459 patients presented with a chest pain evaluation requiring troponin analysis and stress test ordering from the ED. Of these, we studied the 7,988 patients who were discharged home to complete diagnostic testing, having been deemed appropriate by the treating clinicians for an outpatient stress test. The stress test completion rate was 31.3% within 3 days and 58.7% between 4 and 30 days, and 10.0% of patients did not complete the ordered test. The 30-day rates of major adverse cardiac events were low (death 0.0%, acute myocardial infarction 0.7%, and revascularization 0.3%). Rapid receipt of stress testing was not associated with improved 30-day major adverse cardiac events (odds ratio 0.92; 95% confidence interval 0.55 to 1.54). CONCLUSION: Less than one third of patients completed outpatient stress testing within the guideline-recommended 3 days after initial evaluation. More important, the low adverse event rates suggest that selective outpatient stress testing is safe. In this cohort of patients selected for outpatient cardiac stress testing in a well-integrated health system, there does not appear to be any associated benefit of stress testing within 3 days, nor within 30 days, compared with those who never received testing at all. The lack of benefit of obtaining timely testing, in combination with low rates of objective adverse events, may warrant reassessment of the current guidelines.

Impact of Peppermint Therapy on Dysphagia and Non-cardiac Chest Pain: A Pilot Study.

BACKGROUND: Due to its smooth muscle relaxing properties, peppermint oil (PO) may relieve dysphagia and chest pain due to esophageal motility disorders. AIM: To explore the impact of PO on dysphagia and/or chest pain in patients referred for motility testing. METHODS: Patients initiated on PO for dysphagia and/or chest pain from 2013 to 2016 were identified. We excluded patients with obstructing esophageal lesions, patients lost to follow-up, and those with preexisting cardiac conditions. Concentrated PO was given as commercially available dissolvable peppermint tablets; two tablets before meals were prescribed to patients with dysphagia and on an as-needed basis for patients with chest pain. Patient-reported symptom response was assessed using a modified five-point Likert scale. RESULTS: Thirty-eight patients were included. Twenty-four patients (63%) reported improvement; 12 were much better and 12 were slightly better. Fourteen experienced no change and none reported feeling worse. Based on pre-treatment HRM, patients with distal esophageal spasm (DES) (n = 10) and esophagogastric junction outflow obstruction (EGJOO) (n = 8) appeared to demonstrate the best subjective improvement (83% and 100%, respectively) (P < 0.05). CONCLUSION: PO appears to provide symptomatic relief in some patients with dysphagia and CP. Presence of a well-defined manometric disorder, particularly DES or EGJOO, appeared to predict response.

Effect of a HEART Care Pathway on Chest Pain Management Within an Integrated Health System.

STUDY OBJECTIVE: We describe the association of implementing a History, ECG, Age, Risk Factors, and Troponin (HEART) care pathway on use of hospital care and noninvasive stress testing, as well as 30-day patient outcomes in community emergency departments (EDs). METHODS: We performed a prospective interrupted-time-series study of adult encounters for patients evaluated for suspected acute coronary syndrome. The primary outcome was hospitalization or observation, noninvasive stress testing, or both within 30 days. The secondary outcome was 30-day all-cause mortality or acute myocardial infarction. A generalized estimating equation segmented logistic regression model was used to compare the odds of the primary outcome before and after HEART implementation. All models were adjusted for patient and facility characteristics and fit with physicians as a clustering variable. RESULTS: A total of 65,393 ED encounters (before, 30,522; after, 34,871) were included in the study. Overall, 33.5% (before, 35.5%; after, 31.8%) of ED chest pain encounters resulted in hospitalization or observation, noninvasive stress testing, or both. Primary adjusted results found a significant decrease in the primary outcome postimplementation (odds ratio 0.984; 95% confidence interval [CI] 0.974 to 0.995). This resulted in an absolute adjusted month-to-month decrease of 4.39% (95% CI 3.72% to 5.07%) after 12 months' follow-up, with a continued trend downward. There was no difference in 30-day mortality or myocardial infarction (0.6% [before] versus 0.6% [after]; odds ratio 1.02; 95% CI 0.97 to 1.08). CONCLUSION: Implementation of a HEART pathway in the ED evaluation of patients with chest pain resulted in less inpatient care and noninvasive cardiac testing and was safe. Using HEART to risk stratify chest pain patients can improve the efficiency and quality of care.

Diagnosis and Treatment of Slipping Rib Syndrome.

OBJECTIVE: (1) To investigate the clinical presentation, diagnosis, and treatment of slipping rib syndrome in athletes; (2) to investigate the hooking maneuver for diagnosis of slipping rib syndrome. DESIGN: Retrospective chart review of 362 athletes with rib pain. SETTING: Pediatric-based sports medicine clinic between January 1, 1999, and March 1, 2014. PATIENTS: Costochondritis, Tietze, fractures, rib tip syndrome, and unclear diagnoses were excluded. Athletes were included who had a palpable rib subluxation, mechanical rib symptom, positive hooking maneuver, or resolution of pain after the resection of a slipping rib segment. MAIN OUTCOME MEASURES: Slipping rib syndrome is associated with athletic performance. RESULTS: Fifty-four athletes were diagnosed with slipping rib syndrome, of which 38 (70%) were females. Mean age at presentation was 19.1 years (range 4-40 years). Mean number of previous specialist consultations per athlete was 2.3 and mean time from symptom onset to diagnosis was 15.4 months. The hooking maneuver was attempted 21 times (38.9%). Unilateral symptoms presented in 49 athletes (90.7%). The most symptomatic rib was the 10th, affecting 24 athletes (44.4%), eighth and ninth were affected in 17 athletes (31.5%) each. Most, 39 (72.2%), reported insidious onset of symptoms. Running, rowing, lacrosse, and field hockey were frequently associated activities. Twelve athletes had psychiatric diagnoses (22.2%), 10 (19.2%) were hypermobile. Sixty-six total imaging studies were performed. The most successful treatment options included: osteopathic manipulative treatment (71.4%), surgical resection (70%), and diclofenac gel (60%). CONCLUSIONS: Most athletes with slipping rib syndrome were active females with insidious onset of unilateral pain, a high prevalence of hypermobility and prolonged pain. The hooking maneuver was underused.

Non-cardiac chest pain: a 2018 update.

Non-cardiac chest pain (NCCP) is defined as recurring, angina-like, chest pain of non-cardiac origin. Studies have estimated that gastroesophageal reflux disease (GERD) is the most common contributing factor for NCCP. In patients with non-GERD related NCCP, esophageal motility disorders, and functional chest pain of presumed esophageal origin are the main underlying mechanisms for symptoms. Epidemiologic studies show a high prevalence of panic disorder, anxiety and major depression in NCCP patients. The diagnostic esophageal workup starts only after that cardiac and pulmonary diseases have been ruled out. NCCP patients with typical reflux symptoms are more likely to have GERD-related NCCP than those without typical reflux symptoms. High-dose proton pump inhibitor trial (PPI test) can be used to confirm the diagnosis of GERD-related NCCP. Negative upper endoscopy is quite common. For patients unresponsive to antireflux treatment and with negative endoscopy, impedance-pH monitoring should be done. Treatment of patients with non-GERD-related NCCP has focused on esophageal (hypercontractile or spastic) motility disorders and esophageal visceral hypersensitivity. In the first case, several trials using calcium channel blockers, nitrates, anticholinergics, or botulinum toxin injection and recent trials with endoscopic myotomy have been conducted. In case of visceral hypersensitivity, studies found that the amelioration, when compared to placebo, was significant with venlafaxine, sertraline, and imipramine. In this context, also cognitive behavioral therapy has been proposed.

Evaluation of the Effectiveness of a Phone Based Care Coordination Pilot on Hospital Utilisation and Costs for Patients With Chest Pain.

BACKGROUND: A small percentage of the population represents a disproportionate number of attendances at emergency departments (ED). "Frequent presenters" to ED with chest pain do not always fit into established pathways for acute myocardial events. With accelerated "rule out" protocols, patients are often discharged from the ED after short lengths of stay. This research will evaluate the effectiveness of a phone based care-coordination pilot designed to meet the needs of patients attending ED with cardiac and non-cardiac chest pain. METHODS: A longitudinal, single-arm interventional study with retrospectively recruited control group. Ninety-five patients were enrolled as the intervention group; 97 patients were retrospectively identified as controls. These patients had re-presented with chest pain within 6 months of a cardiac event, or attended hospital within 12 months two or more times with chest pain and/or complex needs. Intervention group patients were holistically assessed then phone-coached to support self-management of chest pain over 6 months. Following descriptive and univariate analysis, multivariate analysis was conducted to adjust for noted differences between the intervention and control groups. RESULTS: Thirty-day representation to ED was significantly less for the intervention group (14.1%) compared to controls (27.7%). After adjusting for baseline differences, intervention patients were more than two-fold less likely to re-present compared to controls (OR=0.42, 95%CI: 0.19-0.96). After adjustment for baseline differences, the savings in subsequent inpatient costs was $1588 per person, as a result of intervention, patients were less likely to have inpatient readmissions (16.3%) compared to controls (20.2%), although this was not statistically significant (p=0.588). CONCLUSION: A phone based care-coordination pilot with targeted interventions has the potential to reduce ED presentations and hospital readmissions among patients representing with chest pain.
