Physicians' Perceptions of Clinical Decision Support to Treat Patients With Heart Failure in the ED.

Importance: Clinical decision support (CDS) could help emergency department (ED) physicians treat patients with heart failure (HF) by estimating risk, collating relevant history, and assisting with medication prescribing if physicians' perspectives inform its design and implementation. Objective: To evaluate CDS usability and workflow integration in the hands of ED physician end users who use it in clinical practice. Design, Setting, and Participants: This mixed-methods qualitative study administered semistructured interviews to ED physicians from 2 community EDs of Kaiser Permanente Northern California in 2023. The interview guide, based on the Usability Heuristics for User Interface Design and the Sociotechnical Environment models, yielded themes used to construct an electronic survey instrument sent to all ED physicians. Main Outcomes and Measures: Main outcomes were physicians' perceptions of using CDS to complement clinical decision-making, usability, and integration into ED clinical workflow. Results: Seven key informant physicians (5 [71.4%] female, median [IQR] 15.0 [9.5-15.0] years in practice) were interviewed and survey responses from 51 physicians (23 [45.1%] female, median [IQR] 14.0 [9.5-17.0] years in practice) were received from EDs piloting the CDS intervention. Response rate was 67.1% (51 of 76). Physicians suggested changes to CDS accessibility, functionality, and workflow integration. Most agreed that CDS would improve patient care and fewer than half of physicians expressed hesitation about their capacity to consistently comply with its recommendations, citing workload concerns. Physicians preferred a passive prompt that encouraged, but did not mandate, interaction with the CDS. Conclusions and Relevance: In this qualitative study of physicians who were using a novel CDS intervention to assist with ED management of patients with acute HF, several opportunities were identified to improve usability as well as several key barriers and facilitators to CDS implementation.

Restoratively guided orthodontic treatment: The pre-orthodontic bonding concept.

OBJECTIVE: Communication between the orthodontist and the restorative dentist has always been difficult due to the inability of the orthodontist to achieve the desired orthodontic goals with just words in a referral note. CLINICAL CONSIDERATIONS: A better method of communication is for the restorative dentist to create the ideal tooth anatomy either before or during orthodontic treatment to direct the orthodontic tooth movement. CONCLUSION: It is the purpose of this article to present a technique, which makes the pre-restorative orthodontic treatment both more accurate and more efficient. CLINICAL SIGNIFICANCE: It is very difficult for the orthodontist to move teeth into their correct positions when the teeth are anatomically incorrect due to attrition/erosion or due to developmental malformation. When the restorative dentist makes the teeth anatomically correct with either pre-orthodontic or intermediate orthodontic bonding, the orthodontist has the benefit of ideal tooth anatomy to finalize the tooth positions. This then allows the restorative dentist to create final restorations, which are ideal, both functionally and esthetically.

Oral Apolipoprotein A-I Mimetic D-4F Lowers HDL-Inflammatory Index in High-Risk Patients: A First-in-Human Multiple-Dose, Randomized Controlled Trial.

A single dose of the apolipoprotein (apo)A-I mimetic peptide D-4F rendered high-density lipoprotein (HDL) less inflammatory, motivating the first multiple-dose study. We aimed to assess safety/tolerability, pharmacokinetics, and pharmacodynamics of daily, orally administered D-4F. High-risk coronary heart disease (CHD) subjects added double-blinded placebo or D-4F to statin for 13 days, randomly assigned 1:3 to ascending cohorts of 100, 300, then 500 mg (n = 62; 46 men/16 women). D-4F was safe and well-tolerated. Mean ± SD plasma D-4F area under the curve (AUC, 0-8h) was 6.9 ± 5.7 ng/mL*h (100 mg), 22.7 ± 19.6 ng/mL*h (300 mg), and 104.0 ± 60.9 ng/mL*h (500 mg) among men, higher among women. Whereas placebo dropped HDL inflammatory index (HII) 28% 8 h postdose (range, 1.25-0.86), 300-500 mg D-4F effectively halved HII: 1.35-0.57 and 1.22-0.63, respectively (P < 0.03 vs. placebo). Oral D-4F peptide dose predicted HII suppression, whereas plasma D-4F exposure was dissociated, suggesting plasma penetration is unnecessary. In conclusion, oral D-4F dosing rendered HDL less inflammatory, affirming oral D-4F as a potential therapy to improve HDL function.

A rare cause of constrictive pericarditis.

A 67-year-old man presented with 3 months of exertional dyspnoea and 1 week of oedema. Examination revealed elevated neck veins, pulsus paradoxus, muffled heart sounds, decreased breath sounds and pedal oedema. Transthoracic echocardiogram (TTE) demonstrated cardiac tamponade, and chest X-ray showed pleural effusion. Pericardiocentesis, thoracocentesis, laboratory investigations and CT did not elucidate an underlying aetiology. Three weeks later, he presented with recurrent cardiac tamponade and pleural effusion. Pericardial window histology was benign. Pleural and pericardial fluids were again unrevealing. Three months later, he presented with worsening congestive heart failure. TTE, cardiac catheterisation and cardiac MRI were consistent with constrictive pericarditis. Preoperative workup did not identify an underlying cause. The patient underwent subtotal pericardiectomy. Intraoperative frozen section indicated malignancy. Pathology confirmed metastatic poorly differentiated signet ring adenocarcinoma of intestinal origin. He died 4 days postoperatively from multiorgan failure.

Lean Manufacturing Improves Emergency Department Throughput and Patient Satisfaction.

A multidisciplinary team led by nursing leadership and physicians developed a plan to meet increasing demand and improve the patient experience in the ED without expanding the department's current resources. The approach included Lean tools and engaged frontline staff and physicians. Applying Lean management principles resulted in quicker service, improved patient satisfaction, increased capacity, and reduced resource utilization. Incorporating continuous daily management is necessary for sustainment of continuous improvement activities.

The expanded scope of emergency medical practice necessary for initial disaster response: lessons from Haiti.

A team of emergency physicians and nurses from Stanford University responded to the devastating January 2010 earthquake in Haiti. Because of the extreme nature of the situation, combined with limited resources, the team provided not only acute medical and surgical care to critically injured and ill victims, but was required to uniquely expand its scope of practice. Using a narrative format and discussion, it is the purpose of this paper to highlight our experience in Haiti and use these to estimate some of the skills and capabilities that will be useful for physicians who respond to similar future disasters.

The cutaneous manifestations of metastatic malignant melanoma.

Cutaneous metastases are common sequelae of primary malignant melanoma. Because patients with melanoma are examined frequently after diagnosis, it is important that dermatologists are aware of the range of findings that may represent metastatic disease. Many case reports and a few retrospective series have been published detailing the wide variety of clinical presentations of cutaneous metastatic melanoma. This article reviews the various manifestations of metastatic melanoma of the skin and oral mucous membranes and summarizes treatment options for metastatic disease.

Pediatric erythromelalgia: a retrospective review of 32 cases evaluated at Mayo Clinic over a 37-year period.

BACKGROUND: Erythromelalgia has not been well characterized in the pediatric population. OBJECTIVE: We sought to review our experience of erythromelalgia in the pediatric age group. METHODS: We conducted a retrospective review of patients 18 years of age and younger with a diagnosis of erythromelalgia who were examined at Mayo Clinic in Rochester, MN, from 1970 to 2007. RESULTS: The records of 32 patients (girls, 22 [69%]) were evaluated. Mean age was 14.1 years (range, 5-18 years) and mean time to diagnosis was 5.2 years. Seven patients (22%) had a first-degree relative with erythromelalgia; 4 were from the same family. Physical activity was limited because of discomfort in 21 patients (66%) and school attendance was affected in 11 patients (34%). Noninvasive vascular studies, which compared temperature, laser Doppler flow, and transcutaneous oximetry in the toes, identified vascular abnormalities in 13 (93%) of 14 patients. Neurophysiologic studies with autonomic reflex screening (including quantitative sudomotor axon reflex test and thermoregulatory sweat testing) showed evidence of a small-fiber neuropathy involving the skin in 10 (59%) of 17 patients studied; there was no evidence of large-fiber neuropathy in 20 patients in whom electromyographic and nerve conduction studies were performed. Topical lidocaine was the most commonly prescribed treatment (44%). Fifteen patients were monitored for an average of 9.1 years (median, 5.0 years; range, 0.4-23.7 years). At last follow-up, 5 patients had stable disease, 4 showed improvement, two had resolution, one reported worsening of symptoms, and 3 had died (one suicide). LIMITATIONS: Conclusions are limited because this was a retrospective chart review. CONCLUSION: Erythromelalgia in pediatric patients is associated with substantial morbidity and even death. The majority of cases are not inherited. Most patients studied have associated small-fiber neuropathy. The disease course is variable. A reliable and safe treatment has not been determined.

Iatrogenic immunosuppression and cutaneous malignancy.

Patients with autoimmune and inflammatory conditions often receive long-term immunosuppressive therapy. Some of the largest patient populations with iatrogenic immunosuppression include patients who have received solid-organ transplants or who have rheumatoid arthritis or psoriasis. Although treatments improve patient outcomes, individuals with immunosuppression subsequently may have an increased risk of skin cancer, including squamous cell carcinoma, basal cell carcinoma, and malignant melanoma.

Complications of cutaneous surgery in patients taking clopidogrel-containing anticoagulation.

BACKGROUND: Most anticoagulants are not associated with increased risk of severe complications during cutaneous surgery, but no data exist on clopidogrel. OBJECTIVE: We sought to determine frequency and severity of perioperative complications in patients taking clopidogrel-containing anticoagulation. METHODS: This was a retrospective review of medical records of patients undergoing Mohs micrographic surgery at Mayo Clinic, Rochester, MN, while taking clopidogrel-containing anticoagulation between 2004 and 2008, compared with control subjects taking aspirin monotherapy or no anticoagulants. RESULTS: In all, 220 patients taking clopidogrel-containing anticoagulation underwent 363 surgical procedures on 268 occasions. Severe complications occurred in 11 of 363 surgical sites in 10 cases. Clopidogrel-containing anticoagulation was 28 times more likely than no anticoagulation and 6 times more likely than aspirin monotherapy to result in severe complications after Mohs procedures (P < .001 and P = .022, respectively). Severe complications were 8 times more likely after Mohs procedures in patients taking both clopidogrel and aspirin than in control subjects taking aspirin monotherapy (P = .009). No statistically significant difference was found between patients taking clopidogrel monotherapy and control subjects not taking anticoagulants (P = .15). Patients experiencing severe complications were more likely to have larger postoperative surgical sites (P < .001). No thrombotic complications were encountered with discontinuation of clopidogrel-containing anticoagulation; a postoperative thrombotic complication occurred in one patient whose clopidogrel-containing anticoagulation regimen was modified. LIMITATIONS: Retrospective nature of study, possible recall bias as a result of telephone contact, and small number of severe complications were limitations, which reduced study power. CONCLUSION: Cutaneous surgery in patients taking clopidogrel-containing anticoagulation is associated with an increased risk of nonlife-threatening severe complications.

Allergic contact dermatitis from exotic woods: importance of patch-testing with patient-provided samples.

Exotic woods from tropical and subtropical regions (eg, from South America, south Asia, and Africa) frequently are used occupationally and recreationally by woodworkers and hobbyists. These exotic woods more commonly provoke irritant contact dermatitis reactions, but they also can provoke allergic contact dermatitis reactions. We report three patients seen at Mayo Clinic (Rochester, MN) with allergic contact dermatitis reactions to exotic woods. Patch testing was performed and included patient-provided wood samples. Avoidance of identified allergens was recommended. For all patients, the dermatitis cleared or improved after avoidance of the identified allergens. Clinicians must be aware of the potential for allergic contact dermatitis reactions to compounds in exotic woods. Patch testing should be performed with suspected woods for diagnostic confirmation and allowance of subsequent avoidance of the allergens.

Current procedural terminology coding for Mohs micrographic surgery.

Accurate surgical current procedural terminology (CPT) coding allows for proper reimbursement, decreases the possibility of being audited, and decreases the likelihood of inadvertently misrepresenting a claim. The CPT codes describe the type of services provided to a patient. CPT modifiers provide information to insurance payers to assure that the provider is reimbursed correctly. When coding for reconstruction of a surgical defect, the appropriate code is determined by the type of reconstruction performed. Reconstructive procedures that are performed because of underlying tumors are reimbursed. Adequate documentation is essential, because this substantiates claims and promotes their timely processing.
