Intra-arterial thrombolysis of digital artery occlusions in a patient with polycythemia vera.

There are limited therapeutic options for the resolution of digital artery occlusions. Intra-arterial thrombolysis with anticoagulative and thrombolytic drugs successfully restored the blood flow in the affected digital arteries.

Information structuring improves recall of emergency discharge information: a randomized clinical trial.

This article examines the extent to which structuring Emergency Department discharge information improves the ability to recall that information, and whether such benefits interact with relevant prior knowledge. Using three samples of students with different levels of prior medical knowledge, we investigated the amount of information recalled after structured vs. non-structured presentation of information. Across all student samples, the structured discharge information led to a relative increase in recalled items of 17% compared to non-structured discharge information (M = 9.70, SD = 4.96 vs. M = 8.31, SD = 4.93). In the sample with least medical knowledge, however, the structured discharge information resulted in a relative increase in recall by 42% (M = 8.12 vs. M = 5.71). These results suggest that structuring discharge information can be a useful tool to improve recall of information and is likely to be most beneficial for patient populations with lower levels of medical knowledge.

Increased Bleeding Risk in a Patient with Oral Anticoagulant Therapy and Concomitant Herbal Intake - A Case Report.

We report the case of a 36-year old male, under stable rivaroxaban therapy for 18 months, who was admitted to our emergency room with sudden onset of hemoptysis. Anticoagulant therapy was given after recurrent spontaneous deep vein thrombosis (DVT) and a heterozygous Factor-V-Leiden mutation was present. There was no co-medication reported, however, the patient reported a constant intake of three liters of home-brewn ginger tea per day in the last month. The patient was hospitalized to further investigate the reason of hemoptysis.

Adrenomedullin for Risk Stratification of Emergency Patients With Nonspecific Complaints: An Interventional Multicenter Pilot Study.

Patients with nonspecific complaints (NSC) presenting to the emergency department (ED) are at risk of life-threatening conditions. New stress biomarkers such as the midregional portion of adrenomedullin (MR-proADM) promise to support decision-making. This study tested the following hypotheses: biomarker-assisted disposition of patients with NSC will not increase mortality. Second, discharge from the ED will increase if clinical risk assessment is combined with low MR-proADM levels. Third, inappropriate disposition to a lower level of care will decrease, if clinical assessment is combined with high MR-proADM levels, and fourth that this algorithm is feasible in the ED setting. Prospective, multicenter, randomized, controlled interventional feasibility study with a 30-day follow-up, including patients with NSC. Patients were randomly assigned to either the standard group (decision-making solely based on clinical assessment) or the Novum group (biomarker-assisted). Regarding disposition, patients were assigned to 1 of 3 risk classes: high-risk (admission to hospital), intermediate risk (community geriatric hospital), and low-risk patients (discharge). In the Novum group, in addition to clinical risk assessment, the information of the MR-proADM level was used. Unless there were overruling criteria, patients were transferred or discharged according to the risk assessment. Primary endpoint was 30-day mortality. Secondary endpoints were comparisons of patient disposition and related mortality rates, ED, and hospital length of stay and readmission. The final study cohort consisted of 398 patients (210 in the Standard group and 188 in the Novum group). Overruling, that is, disposition not according to the result of the proposed algorithm occurred in 51 cases. Baseline characteristics between Standard and Novum groups were similar. The mortality rate in the Novum group was 4.3%, as compared to the Standard group mortality of 6.2%, which was not significantly different (intention-to treat analysis). This was confirmed by the perprotocol analysis as well as by sensitivity analysis. For the secondary endpoints, no significant differences were detected. Biomarker-assisted disposition is safe in patients with NSC. Discharge rates did not increase. Feasibility could only partly be shown due to an unexpectedly high overruling rate. Inappropriate disposition to lower levels of care did not change. ClinicalTrials. gov Identifier: NCT00920491.

Improving patient recall of information: Harnessing the power of structure.

OBJECTIVE: Assess the amount of medical information laypeople recall, investigate the impact of structured presentation on recall. METHODS: 105 first-year psychology students (mean age 21.5±3.8 years; 85% female) were randomised to two information-presentation conditions: structured (S group) and nonstructured (NS group). Students watched a video of a physician discharging a patient from the emergency department. In the S Group, content (28 items of information) was divided into explicit "chapters" with "chapter headings" preceding new information. Afterwards, participants wrote down all information they recalled on an empty sheet of paper. RESULTS: The S group (N=57) recalled significantly more items than NS group (N=41) (8.12±4.31 vs. 5.71±3.73; p=0.005), rated information as easier to understand (8.0±1.9 vs. 6.1±2.2; p<0.001) and better structured (8.5±1.5 vs. 5.5±2.7; p<0.001); they rather recommended the physician to friends (7.1±2.7 vs. 5.8±2.6; p<0.01). CONCLUSION: University students recalled around 7/28 items of information presented. Explicit structure improved recall. PRACTICE IMPLICATIONS: Practitioners must reduce the amount of information conveyed and structure information to improve recall.

The proportion of correct diagnoses is low in emergency patients with nonspecific complaints presenting to the emergency department.

OBJECTIVE: To determine the proportion of correct emergency department (ED) diagnoses and of hospital discharge diagnoses, in comparison with final diagnoses at the end of a 30-day follow-up, in patients presenting with nonspecific complaints (NSCs) to the ED; to determine differences between male and female patients in the proportion of missed diagnoses. METHODS: Prospective observational study. Diagnoses made at the ED, hospital discharge diagnoses, and final diagnoses were compared. RESULTS: Of 22,782 nontrauma patients presenting to the ED from May 2007 until May 2009, 9,926 were triaged as emergency severity index level 2 or 3, of whom 789 presented with NSCs. After exclusion of 217 patients, 572 were included for final analysis. The final diagnosis at the end of follow-up was taken to be the correct "gold standard" diagnosis. In 263 (46.0%) patients, this corresponded to the primary ED diagnosis, and in 292 (51%) patients to the hospital discharge diagnosis. The most frequent final diagnoses were urinary tract infections (n=49), electrolyte disorders (n=40) and pneumonia (n=37), and were correctly diagnosed at the ED in 23, 21 and 27 patients, respectively. Of the twelve most common diagnoses (corresponding to 354 patients), functional impairment was most frequently missed. Among these 354 patients, diagnoses were significantly more often missed in women than in men (142 of 231 [62%] women vs 57 of 123 [46%] men, p=0.004). CONCLUSION: Patients presenting to the ED with NSCs present a diagnostic challenge. New diagnostic tools are needed to help in the diagnosis of these patients.
