The Effect of Health Literacy on a Brief Intervention to Improve Advance Directive Completion: A Randomized Controlled Study.

OBJECTIVE: Completion of an advance directive (AD) document is one component of advanced care planning. We evaluated a brief intervention to enhance AD completion and assess whether the intervention effect varied according to health literacy. METHODS: A randomized controlled study was conducted in 2 internal medicine clinics. Participants were over 50, without documented AD, no diagnosis of dementia, and spoke English. Participants were screened for health literacy utilizing REALM-SF. Participants were randomized in a 1:1 ratio to the intervention, a 15-minute scripted introduction (grade 7 reading level) to our institution's AD forms (grade 11 reading level) or to the control, in which subjects were handed blank AD forms without explanation. Both groups received reminder calls at 1, 3, and 5 months. The primary outcome was AD completion at 6 months. RESULTS: Five hundred twenty-nine subjects were enrolled; half were of limited and half were of adequate health literacy. The AD completion rate was 21.7% and was similar in the intervention vs. the control group (22.4% vs 22.2%, P = .94).More participants with adequate health literacy completed an AD than those with limited health literacy (28.4% vs 16.2%, P = .0008), although the effect of the intervention was no different within adequate or limited literacy groups. CONCLUSION: A brief intervention had no impact on AD completion for subjects of adequate or limited health literacy. PRACTICE IMPLICATIONS: Our intervention was designed for easy implementation and to be accessible to patients of adequate or limited health literacy. This intervention was not more likely than the control (handing patients an AD form) to improve AD completion for patients of either limited or adequate health literacy. Future efforts and research to improve AD completion rates should focus on interventions that include: multiple inperson contacts with patients, contact with a trusted physician, documents at 5th grade reading level, and graphic/video decision aids. TRIAL REGISTRATION NUMBER: NCT02702284, Protocol ID IRB201500776.

Design and Early Implementation Successes and Challenges of a Pharmacogenetics Consult Clinic.

Pharmacogenetic testing (PGT) is increasingly being used as a tool to guide clinical decisions. This article describes the development of an outpatient, pharmacist-led, pharmacogenetics consult clinic within internal medicine, its workflow, and early results, along with successes and challenges. A pharmacogenetics-trained pharmacist encouraged primary care physicians (PCPs) to refer patients who were experiencing side effects/ineffectiveness from certain antidepressants, opioids, and/or proton pump inhibitors. In clinic, the pharmacist confirmed the need for and ordered CYP2C19 and/or CYP2D6 testing, provided evidence-based pharmacogenetic recommendations to PCPs, and educated PCPs and patients on the results. Operational and clinical metrics were analyzed. In two years, 91 referred patients were seen in clinic (mean age 57, 67% women, 91% European-American). Of patients who received PGT, 77% had at least one CYP2C19 and/or CYP2D6 phenotype that would make conventional prescribing unfavorable. Recommendations suggested that physicians change a medication/dose for 59% of patients; excluding two patients lost to follow-up, 87% of recommendations were accepted. Challenges included PGT reimbursement and referral maintenance. High frequency of actionable results suggests physician education on who to refer was successful and illustrates the potential to reduce trial-and-error prescribing. High recommendation acceptance rate demonstrates the pharmacist's effectiveness in providing genotype-guided recommendations, emphasizing a successful pharmacist-physician collaboration.

Case of Serotonin Syndrome Initially Presenting as Diffuse Body Pain.

BACKGROUND Serotonin syndrome is a common yet potentially life-threatening condition caused by increased serotonergic activity, usually from serotonergic pharmaceutical agents. Primary features of serotonin syndrome include mental status changes, autonomic hyperactivity, and neuromuscular abnormalities. However, the presentation of serotonin syndrome is often quite variable, leading to its under-diagnosis. CASE REPORT A 50-year-old female with chronic kidney disease on peritoneal dialysis presented to the Emergency Department with severe, diffuse body pain. Over the course of her hospital stay, she developed severe nausea, vomiting, and diarrhea followed by hyperreflexia and inducible clonus. Laboratory studies were remarkable for elevated liver transaminases. Review of her medications revealed several serotonergic agents, including duloxetine, tramadol, and ondansetron. Given her symptoms and the multiple serotonergic agents she was taking, she was diagnosed with serotonin syndrome. Discontinuation of the serotonergic agents led to resolution of her symptoms over the course of 4 days. CONCLUSIONS Our patient's initial presentation of diffuse body pain highlights the variable presentation of serotonin syndrome. Our case also demonstrates the importance of recognizing serotonin syndrome, as the supportive ondansetron we gave to alleviate her nausea and vomiting likely exacerbated her serotonin syndrome.

A difficult situation - balancing critical anticoagulation versus the risk of permanent neurologic deficit: a case report.

BACKGROUND: Anticoagulation is the mainstay of treatment for pulmonary embolism. However, if bleeding unfortunately occurs, the risks and benefits of anticoagulation present a challenge. Management of one hemorrhagic complication, retroperitoneal hematoma, is rare, difficult, and controversial. CASE PRESENTATION: A 73-year-old white man presented with left lower extremity swelling and dyspnea. He was tachycardic, hypertensive, and demonstrated poor oxygen saturation of 81% on ambient air. A computed tomography angiogram revealed a saddle pulmonary embolus. Tissue plasminogen activator was administered and he was started on a heparin infusion. He was eventually transitioned to enoxaparin. On the day of discharge, however, he had sudden onset of right leg numbness and weakness below his hip. A computed tomography of his head was not concerning for stroke, and neurology was consulted. Neurology was concerned for spinal cord infarction versus hematoma and recommended magnetic resonance imaging of his thoracic and lumbar spine. The magnetic resonance imaging revealed a left psoas hematoma. A computed tomography scan of his pelvis also showed a right psoas and iliacus hematoma. He was transitioned to a low intensity heparin infusion. The following day his left leg exhibited similar symptoms. There was concern of progressive and irreversible nerve damage due to compression if the hematomas were not drained. Interventional radiology was consulted for drainage. The heparin infusion was paused, drainage was performed, and the heparin infusion was reinitiated 6 hours following the procedure by interventional radiology. His blood counts and neurologic examination stabilized and eventually improved. He was discharged home on a novel anticoagulant. CONCLUSIONS: Management of a retroperitoneal hematoma can commence with recognition of the warning signs of bleeding and neurological impairment, and consulting the appropriate services in case the need for intervention arises. A conservative approach of volume resuscitation and blood transfusion can be used initially, with the need for pausing or reversing anticoagulation being assessed on an individual basis with expert consultation. If intervention becomes necessary, other interventional radiology-based modalities can be used to identify and stop the bleeding source, and interventional radiology-guided drainage can be performed to decrease the hematoma burden and relieve neurological symptoms.

Recurrent blistering distal dactylitis due to Staphylococcus aureus in an immunocompetent elderly woman.

An 86-year-old woman presented with marked blistering of her left index fingertip and ulceration of the left middle fingertip, with a 2-year history of recurrent blistering and ulceration of her fingers bilaterally. She denied any preceding finger trauma, although she reported frequent gardening. She denied systemic symptoms. Her medical history was significant for a 2-year history of atrial fibrillation on carvedilol, amiodarone and apixaban, and she was a lifetime non-smoker. On admission, she had elevated inflammatory markers but unremarkable autoantibodies. Radiograph of the hand revealed diffuse soft tissue fullness and subtle irregularities at the tuft of the index finger, but all other investigations were unremarkable. The lesion was incised and drained, revealing blood-tinged purulent fluid. Wound biopsy revealed spongiosis with neutrophils, consistent with a diagnosis of blistering distal dactylitis.

Template-assisted assembly of the functionalized cubic and spherical microparticles.

The patterned template-assisted assembly of the cubic microparticles driven by the competing capillary, Columbic, and van der Waals forces had been studied in comparison with the traditional spherical colloidal microparticles. We observed that the spherical and cubic microparticles assembled with different probability in the channels of the hydrophobic-hydrophilic patterned substrates due to differences in a balance of adhesive and capillary forces. In contrast to highly selective assembly of spherical microparticles, selective deposition of cubic microcrystals with channels is impeded by strong adhesive forces facilitated by large specific interfacial areas between cube facets and substrate. The modification of the patterned substrate by functionalized coatings with oppositely charged topmost layers significantly increases the probability (to 86%) of the cubic microparticles to assemble into chemically modified channels. The introduction of ultrathin LbL shells on cubic microparticles and functionalization of patterned substrates are critical for the directed colloidal assembly of anisotropic microparticles into ordered aggregates.
