Clinical Features and Outcomes Associated with Angioedema in the Emergency Department.

INTRODUCTION: Angioedema represents self-limited, localized swelling of submucosal or subcutaneous tissues. While the underlying etiology may be undeterminable in the emergent setting, nonhistaminergic and histaminergic angioedema respond differently to therapeutic interventions, with implications for empiric treatment. Clinical features and outcome differences among nonhistaminergic vs histaminergic angioedema patients in the emergency department (ED) are poorly characterized. We aim to describe the clinical characteristics and outcomes among ED patients with angioedema by suspected etiology. METHODS: This was a 10-year retrospective study of adult ED patients with angioedema, using data abstracted from the electronic health record. We evaluated univariable associations of select clinical features with etiology and used them to develop a multivariable logistic regression model for nonhistaminergic vs histaminergic angioedema. RESULTS: Among 450 adult angioedema patients, the mean +/- standard deviation age was 57 +/- 18 years, and 264 (59%) were female. Among patients, 30% had suspected nonhistaminergic angioedema, 30% had suspected histaminergic angioedema, and 40% were of unknown etiology. As compared to histaminergic angioedema, nonhistaminergic angioedema was associated with angiotensin-converting enzyme inhibitors (ACEI) or use of angiotensin II receptor blockers (ARB) (odds ratio [OR] [60.9]; 95% confidence interval [CI], 23.16-160.14) and time of onset one hour or more prior to ED arrival (OR [5.91]; 95% CI,1.87-18.70) and was inversely associated with urticaria (OR [0.05]; 95% CI, 0.02-0.15), dyspnea (OR [0.23]; 95% CI, 0.08-0.67), and periorbital or lip edema (OR [0.25]; 95% CI, 0.08-0.79 and OR [0.32]; 95% CI, 0.13-0.79, respectively). CONCLUSION: As compared to histaminergic angioedema, patients with nonhistaminergic angioedema were more likely to present one hour or more after symptom onset and take ACEI or ARB medications, and were less likely to have urticaria, dyspnea, or periorbital or lip angioedema. Identification of characteristics associated with the etiology of angioedema may assist providers in more rapidly initiating targeted therapies.

Women's Values and Preferences Regarding Osteoporosis Treatments: A Systematic Review.

BACKGROUND: Several treatments are available to reduce the risk of fragility fractures associated with osteoporosis. The choice of treatment requires knowledge of patients' values and preferences. The aim of the present study was to summarize what is known about the values and preferences relevant to the management of osteoporosis in women. METHODS: We conducted a comprehensive search of several databases for studies reported in any language that had included women who had already started or were about to start any pharmacological therapy for osteoporosis. Pairs of reviewers independently selected the studies and extracted the data. The results were synthesized narratively. RESULTS: We included 26 studies reporting on 15,348 women (mean age, 66 years). The women considered the effectiveness and adverse events equally, followed by the convenience of taking the drug and its effect on daily routine (less frequent dosing was preferred, the oral route was preferred, and the injectable route was preferred over oral if given less frequently). The treatment cost and duration were less important factors for decision making. Fear of breast cancer and fear of resuming uterine bleeding were common reasons for not choosing estrogen therapy. Calcium and vitamin D were viewed as safe and natural. Across the studies, the preferences were not affected by age, previous drug exposure, or employment status. CONCLUSIONS: Women starting osteoporosis medications value effectiveness and side effects equally and prefer medications given less frequently. Injectable drugs appear acceptable if given less frequently. More research on patient values and preferences is needed to guide decision making in osteoporosis.

Eliciting the Patient's Agenda- Secondary Analysis of Recorded Clinical Encounters.

BACKGROUND: Eliciting patient concerns and listening carefully to them contributes to patient-centered care. Yet, clinicians often fail to elicit the patient's agenda and, when they do, they interrupt the patient's discourse. OBJECTIVE: We aimed to describe the extent to which patients' concerns are elicited across different clinical settings and how shared decision-making tools impact agenda elicitation. DESIGN AND PARTICIPANTS: We performed a secondary analysis of a random sample of 112 clinical encounters recorded during trials testing the efficacy of shared decision-making tools. MAIN MEASURES: Two reviewers, working independently, characterized the elicitation of the patient agenda and the time to interruption or to complete statement; we analyzed the distribution of agenda elicitation according to setting and use of shared decision-making tools. KEY RESULTS: Clinicians elicited the patient's agenda in 40 of 112 (36%) encounters. Agendas were elicited more often in primary care (30/61 encounters, 49%) than in specialty care (10/51 encounters, 20%); p = .058. Shared decision-making tools did not affect the likelihood of eliciting the patient's agenda (34 vs. 37% in encounters with and without these tools; p = .09). In 27 of the 40 (67%) encounters in which clinicians elicited patient concerns, the clinician interrupted the patient after a median of 11 seconds (interquartile range 7-22; range 3 to 234 s). Uninterrupted patients took a median of 6 s (interquartile range 3-19; range 2 to 108 s) to state their concern. CONCLUSIONS: Clinicians seldom elicit the patient's agenda; when they do, they interrupt patients sooner than previously reported. Physicians in specialty care elicited the patient's agenda less often compared to physicians in primary care. Failure to elicit the patient's agenda reduces the chance that clinicians will orient the priorities of a clinical encounter toward specific aspects that matter to each patient.

Patients' knowledge about the outcomes of thyroid biopsy: a patient survey.

PURPOSE: Fine-needle aspiration biopsy of the thyroid is an increasingly common outpatient procedure. Patients are counseled about the indications and risks of this procedure and informed consent is obtained. We aimed to assess the extent to which patients acquired necessary knowledge during this process. METHODS: Survey study conducted in a thyroid nodule clinic at a referral center. Adult patients who had just undergone a thyroid biopsy were asked to complete a survey, including eight questions regarding the indications and potential outcomes of thyroid biopsy. The main outcome of the study was to assess the patients' knowledge based on the response to each individual survey question. RESULTS: Two-hundred and ninety-seven patients were eligible, of which 196 (66%) completed the survey: most were women (76%), had adequate reading health literacy (95%) and a mean age of 58 years. Although 86% of patients correctly identified evaluation for thyroid cancer as the main indication for their biopsy, 56% were not aware of the likelihood of this diagnosis. Almost all (>90%) of respondents knew that results could be benign or malignant; fewer were aware of non-diagnostic (71%) or indeterminate (68%) outcomes, or of the need for additional diagnostic testing after the biopsy (33%). CONCLUSIONS: After undergoing thyroid biopsy, a high proportion of well-educated patients remained unaware of their risk for thyroid cancer, potential outcomes, and downstream consequences of their biopsy. This quality gap raises the possibility that informed consent procedures that meet legal standards may leave patients undergoing thyroid biopsy paradoxically uninformed.

Weight Changes After Thyroid Surgery for Patients with Benign Thyroid Nodules and Thyroid Cancer: Population-Based Study and Systematic Review and Meta-Analysis.

BACKGROUND: A key concern among patients who undergo thyroid surgery is postoperative weight gain. Yet, the impact of thyroid surgery on weight is unclear. METHODS: The population-based Rochester Epidemiology Project was used to examine weight and body mass index (BMI) changes at one, two, and three years of follow-up in (i) patients with thyroid cancer and benign thyroid nodules after thyroid surgery, and (ii) patients with thyroid nodules who did not have surgery. A comprehensive systematic review of the published literature from inception to February 2016 was also conducted. The results were pooled across studies using a random effects model. RESULTS: A total of 435 patients were identified: 181 patients with thyroid cancer who underwent surgery (group A), 226 patients with benign thyroid nodules without surgery (group B), and 28 patients with benign thyroid nodules undergoing surgery (group C). Small changes in mean weight, BMI, and the number of patients whose weight increased between 5 and 10 kg were similar during each year of follow-up between patients in groups A and B. Furthermore, age >50 years, female sex, baseline BMI >25 kg/m2, and thyrotropin value at one to two years were not predictors of a 5% weight change. In the meta-analysis, 11 studies were included. One to two years after surgery for thyroid cancer or thyroid nodules, patients gained on average 0.94 kg [confidence interval (CI) 0.58-1.33] and 1.07 kg [CI 0.26-1.87], respectively. Patients with benign thyroid nodules who did not have surgery gained 1.50 kg [CI 0.60-2.4] at the longest follow-up. CONCLUSIONS: On average, patients receiving care for thyroid nodules or cancer gain weight, but existing evidence suggests that surgery for these conditions does not contribute significantly to further weight gain. Clinicians and patients can use this information to discuss what to expect after thyroid surgery.

Humor During Clinical Practice: Analysis of Recorded Clinical Encounters.

OBJECTIVE: Little is known about humor's use in clinical encounters, despite its many potential benefits. We aimed to describe humor during clinical encounters. DESIGN: We analyzed 112 recorded clinical encounters. Two reviewers working independently identified instances of humor, as well as information surrounding the logistics of its use. RESULTS: Of the 112 encounters, 66 (59%) contained 131 instances of humor. Humor was similarly frequent in primary care (36/61, 59%) and in specialty care (30/51, 59%), was more common in gender-concordant interactions (43/63, 68%), and was most common during counseling (81/112, 62%). Patients and clinicians introduced humor similarly (63 vs 66 instances). Typically, humor was about the patient's medical condition (40/131, 31%). DISCUSSION AND CONCLUSION: Humor is used commonly during counseling to discuss the patient's medical condition and to relate to general life events bringing warmth to the medical encounter. The timing and topic of humor and its use by all parties suggests humor plays a role in the social connection between patients and physicians and allows easier discussion of difficult topics. Further research is necessary to establish its impact on clinicians, patients, and outcomes.

Shared decision making in patients with low risk chest pain: prospective randomized pragmatic trial.

OBJECTIVE:  To compare the effectiveness of shared decision making with usual care in choice of admission for observation and further cardiac testing or for referral for outpatient evaluation in patients with possible acute coronary syndrome. DESIGN:  Multicenter pragmatic parallel randomized controlled trial. SETTING:  Six emergency departments in the United States. PARTICIPANTS:  898 adults (aged >17 years) with a primary complaint of chest pain who were being considered for admission to an observation unit for cardiac testing (451 were allocated to the decision aid and 447 to usual care), and 361 emergency clinicians (emergency physicians, nurse practitioners, and physician assistants) caring for patients with chest pain. INTERVENTIONS:  Patients were randomly assigned (1:1) by an electronic, web based system to shared decision making facilitated by a decision aid or to usual care. The primary outcome, selected by patient and caregiver advisers, was patient knowledge of their risk for acute coronary syndrome and options for care; secondary outcomes were involvement in the decision to be admitted, proportion of patients admitted for cardiac testing, and the 30 day rate of major adverse cardiac events. RESULTS:  Compared with the usual care arm, patients in the decision aid arm had greater knowledge of their risk for acute coronary syndrome and options for care (questions correct: decision aid, 4.2 v usual care, 3.6; mean difference 0.66, 95% confidence interval 0.46 to 0.86), were more involved in the decision (observing patient involvement scores: decision aid, 18.3 v usual care, 7.9; 10.3, 9.1 to 11.5), and less frequently decided with their clinician to be admitted for cardiac testing (decision aid, 37% v usual care, 52%; absolute difference 15%; P<0.001). There were no major adverse cardiac events due to the intervention. CONCLUSIONS:  Use of a decision aid in patients at low risk for acute coronary syndrome increased patient knowledge about their risk, increased engagement, and safely decreased the rate of admission to an observation unit for cardiac testing.Trial registration ClinicalTrials.gov NCT01969240.

Shared Decision Making With Vulnerable Populations in the Emergency Department.

The emergency department (ED) occupies a unique position within the healthcare system, serving as a safety net for vulnerable patients, regardless of their race, ethnicity, religion, country of origin, sexual orientation, socioeconomic status, or medical diagnosis. Shared decision making (SDM) presents special challenges when used with vulnerable population groups. The differing circumstances, needs, and perspectives of vulnerable groups invoke issues of provider bias, disrespect, judgmental attitudes, and lack of cultural competence, as well as patient mistrust and the consequences of their social and economic disenfranchisement. A research agenda that includes community-engaged approaches, mixed-methods studies, and cost-effectiveness analyses is proposed to address the following questions: 1) What are the best processes/formats for SDM among racial, ethnic, cultural, religious, linguistic, social, or otherwise vulnerable groups who experience disadvantage in the healthcare system? 2) What organizational or systemic changes are needed to support SDM in the ED whenever appropriate? 3) What competencies are needed to enable emergency providers to consider patients' situation/context in an unbiased way? 4) How do we teach these competencies to students and residents? 5) How do we cultivate these competencies in practicing emergency physicians, nurses, and other clinical providers who lack them? The authors also identify the importance of using accurate, group-specific data to inform risk estimates for SDM decision aids for vulnerable populations and the need for increased ED-based care coordination and transitional care management capabilities to create additional care options that align with the needs and preferences of vulnerable populations.

Non-pharmacological treatment of depression: a systematic review and evidence map.

BACKGROUND: The comparative effectiveness of non-pharmacological treatments of depression remains unclear. METHODS: We conducted an overview of systematic reviews to identify randomised controlled trials (RCTs) that compared the efficacy and adverse effects of non-pharmacological treatments of depression. We searched multiple electronic databases through February 2016 without language restrictions. Pairs of reviewers determined eligibility, extracted data and assessed risk of bias. Meta-analyses were conducted when appropriate. RESULT: We included 367 RCTs enrolling ∼20 000 patients treated with 11 treatments leading to 17 unique head-to-head comparisons. Cognitive behavioural therapy, naturopathic therapy, biological interventions and physical activity interventions reduced depression severity as measured using standardised scales. However, the relative efficacy among these non-pharmacological interventions was lacking. The effect of these interventions on clinical response and remission was unclear. Adverse events were lower than antidepressants. LIMITATION: The quality of evidence was low to moderate due to inconsistency and unclear or high risk of bias, limiting our confidence in findings. CONCLUSIONS: Non-pharmacological therapies of depression reduce depression symptoms and should be considered along with antidepressant therapy for the treatment of mild-to-severe depression. A shared decision-making approach is needed to choose between non-pharmacological therapies based on values, preferences, clinical and social context.

Metabolic control in patients with type 2 diabetes mellitus in a public hospital in Peru: a cross-sectional study in a low-middle income country.

OBJECTIVE: The objective of this study was to assess patients' achievement of ADA (American Diabetes Association) guideline recommendations for glycosylated hemoglobin, lipid profile, and blood pressure in a type 2 diabetes mellitus (T2DM) outpatient clinic in a low-middle income country (LMIC) setting. METHODS: This is a descriptive cross-sectional study with 123 ambulatory T2DM patients who are being treated at a public hospital in Lima, Peru. Data was gathered via standardized interviews, clinical surveys, and anthropomorphic measurements for each patient. Blood samples were drawn in fasting state for measures of glucose, glycosylated hemoglobin (HbA1c), and lipid profile. Laboratory parameters and blood pressure were evaluated according to ADA recommendations. RESULTS: Of the 123 patients, 81 were women and the mean age was 61.8 years. Glycemic control was abnormal in 82 (68.33%) participants, and 45 (37.50%) were unable to control their blood pressure. Lipid profile was abnormal in 73 (60.83%) participants. Only nine (7.50%) participants fulfilled ADA recommendations for glycemic, blood pressure, and lipid control. CONCLUSIONS: Amongst individuals with type 2 diabetes, there was poor attainment of the ADA recommendations (HbA1c, blood pressure and LDL-cholesterol) for ambulatory T2DM patients. Interventions are urgently needed in order to prevent long-term diabetic complications.

Patient capacity and constraints in the experience of chronic disease: a qualitative systematic review and thematic synthesis.

BACKGROUND: Life and healthcare demand work from patients, more so from patients living with multimorbidity. Patients must respond by mobilizing available abilities and resources, their so-called capacity. We sought to summarize accounts of challenges that reduce patient capacity to access or use healthcare or to enact self-care while carrying out their lives. METHODS: We conducted a systematic review and synthesis of the qualitative literature published since 2000 identifying from MEDLINE, EMBASE, Psychinfo, and CINAHL and retrieving selected abstracts for full text assessment for inclusion. After assessing their methodological rigor, we coded their results using a thematic synthesis approach. RESULTS: The 110 reports selected, when synthesized, showed that patient capacity is an accomplishment of interaction with (1) the process of rewriting their biographies and making meaningful lives in the face of chronic condition(s); (2) the mobilization of resources; (3) healthcare and self-care tasks, particularly, the cognitive, emotional, and experiential results of accomplishing these tasks despite competing priorities; (4) their social networks; and (5) their environment, particularly when they encountered kindness or empathy about their condition and a feasible treatment plan. CONCLUSION: Patient capacity is a complex and dynamic construct that exceeds "resources" alone. Additional work needs to translate this emerging theory into useful practice for which we propose a clinical mnemonic (BREWS) and the ICAN Discussion Aid.

Shared Decision Making in the Emergency Department Among Patients With Limited Health Literacy: Beyond Slower and Louder.

Although studies suggest that patients with limited health literacy and/or low numeracy skills may stand to gain the most from shared decision making (SDM), the impact of these conditions on the effective implementation of SDM in the emergency department (ED) is not well understood. In this article from the proceedings of the 2016 Academic Emergency Medicine Consensus Conference on Shared Decision Making in the Emergency Department we discuss knowledge gaps identified and propose consensus-driven research priorities to help guide future work to improve SDM for this patient population in the ED.

Effect of scribes on patient throughput, revenue, and patient and provider satisfaction: a systematic review and meta-analysis.

BACKGROUND: Scribes offer a potential solution to the clerical burden and time constraints felt by health care providers. OBJECTIVES: This is a systematic review and meta-analysis to evaluate scribe effect on patient throughput, revenue, and patient and provider satisfaction. METHODS: Six electronic databases were systematically searched from inception until May 2015. We included studies where clinicians used a scribe. We collected throughput metrics, billing data, and patient/provider satisfaction data. Meta-analyses were conducted using a random effects model and mean differences (MDs) with 95% confidence intervals (CIs) with adherence to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis statement. RESULTS: From a total of 210 titles, 17 studies were eligible and included. Qualitative analysis suggests improvement in provider/patient satisfaction. Meta-analysis on throughput data was derived from 3 to 5 studies depending on the metric; meta-analysis revealed no impact of scribes on length of stay (346 minutes for scribes, 344 minutes for nonscribed; MD -1.6 minutes, 95% CI -22.3 to 19.2 minutes) or provider-to-disposition time (235 minutes for scribes, 216 for nonscribed; MD -18.8 minutes, 95% CI -22.3 to 19.2) with an increase in patients seen per hour (0.17 more patient per hour; 95% CI 0.02-32). Two studies reported relative value units, which increased 0.21 (95% CI 0-0.42) per patient with scribe use. CONCLUSION: We found no difference in length of stay or time to disposition with a small increase in the number of patients per hour seen when using scribes. Potential benefits include revenue and patient/provider satisfaction.

Diagnostic accuracy of ultrasound-guided fine needle aspiration biopsy for thyroid malignancy: systematic review and meta-analysis.

PURPOSE: To systematically appraise and summarize the available evidence about the diagnostic accuracy of ultrasound-guided fine needle aspiration biopsy (USFNA) for thyroid malignancy, and to explore the integration of these estimates with the probability of thyroid malignancy before USFNA. METHODS: A comprehensive search of multiple databases from each database's inception to August 2014 was performed. Eligible studies included those that evaluated patients with thyroid nodules who underwent USFNA and subsequent evaluation by histopathology or long-term follow-up. RESULTS: We identified 32 studies at moderate risk of bias evaluating the USFNA diagnostic characteristics for the diagnosis of thyroid malignancy. Results were imprecise and inconsistent across trials. The pooled likelihood ratio (LR) of thyroid malignancy for a benign USFNA result was 0.09 (95 % CI 0.06, 0.14; I (2) = 33 %), whereas the pooled LR for a malignant result was 197 (95 % CI, 68, 569; I (2) = 77 %). In the case of a suspicious for follicular neoplasm result, the pooled LR for malignancy was 0.6 (95 % CI, 0.4, 1.0; I (2) = 84 %) and 8.3 (95 % CI, 3.6, 19.2; I (2) = 89) for a result of suspicious for malignancy. CONCLUSION: The available evidence regarding the diagnostic accuracy of USFNA warrants only limited confidence due to risk of bias, imprecision, and inconsistency. However, some USFNA results (benign, malignant) are likely very helpful, by significantly changing the pre-test probability of thyroid cancer.

Outcomes of Parathyroidectomy in Patients with Primary Hyperparathyroidism: A Systematic Review and Meta-analysis.

BACKGROUND: Parathyroidectomy is a definitive treatment for primary hyperparathyroidism. Patients contemplating this intervention will benefit from knowledge regarding the expected outcomes and potential risks of the currently available surgical options. PURPOSE: To appraise and summarize the available evidence regarding benefits and harms of minimally invasive parathyroidectomy (MIP) and bilateral neck exploration (BNE). DATA SOURCES: A comprehensive search of multiple databases (MEDLINE, EMBASE, and Scopus) from each database's inception to September 2014 was performed. STUDY SELECTION: Eligible studies evaluated patients with primary hyperparathyroidism undergoing MIP or BNE. DATA EXTRACTION: Reviewers working independently and in duplicate extracted data and assessed the risk of bias. DATA SYNTHESIS: We identified 82 observational studies and 6 randomized trials at moderate risk of bias. Most of them reported outcomes after MIP (n = 71). Using random-effects models to pool results across studies, the cure rate was 98 % (95 % CI 97-98 %, I (2) = 10 %) with BNE and 97 % (95 % CI 96-98 %, I (2) = 86 %) with MIP. Hypocalcemia occurred in 14 % (95 % CI 10-17 % I (2) = 93 %) of the BNE cases and in 2.3 % (95 % CI 1.6-3.1 %, I (2) = 87 %) with MIP (P < 0.001). There was a statistically significant lower risk of laryngeal nerve injury with MIP (0.3 %) than with BNE (0.9 %), but similar risk of infection (0.5 vs. 0.5 %) and mortality (0.1 vs. 0.5 %). LIMITATIONS: The available evidence, mostly observational, is at moderate risk of bias, and limited by indirect comparisons and inconsistency for some outcomes (cure rate, hypocalcemia). CONCLUSION: MIP and BNE are both effective surgical techniques for the treatment of primary hyperparathyroidism. The safety profile of MIP appears superior to BNE (lower rate of hypocalcemia and recurrent laryngeal nerve injury).

Development and Pilot Testing of an Encounter Tool for Shared Decision Making About the Treatment of Graves' Disease.

BACKGROUND: The best treatment option for patients with Graves' disease (GD) depends on each person's situation and how the differences between the treatment options matter to them in bringing resolution to their illness. The objective of this study was to develop and test an encounter decision tool (GD Choice) for patients and clinicians to engage in shared decision making about the treatment of GD. METHODS: GD Choice was developed using an iterative process based on the principles of interaction design and participatory action research. To evaluate the impact of the tool, a controlled before-after study was conducted, assessing the use of GD Choice versus usual care (UC). RESULTS: Sixty-eight patients were enrolled, 37 to UC and 31 to GD Choice. At baseline, the groups were similar. Treatment discussion length was similar in both arms. After their visit, patients in both groups had similar knowledge about the options, except for GD Choice patients knowing significantly more about the complications of treatment (correctly answered by 83% vs. 55%; p = 0.04). Compared with UC, patients in the GD Choice arm had greater involvement in decision making observed on video recordings of clinical encounters (mean OPTION scale score, 35% vs. 30%; p = 0.02), but reported similar levels of decisional comfort and participation in shared decision making. CONCLUSIONS: GD Choice increases engagement in the decision-making process and knowledge regarding intervention complications without increasing the length of consultation. These promising results support the conduct of a randomized trial of GD Choice versus UC in a large multicenter trial.
