Reducing Racial Disparities in the Timeliness of Potential Lung Cancer Evaluation With a Novel Application-Supported Rapid Outpatient Diagnostic Program: An Interrupted Time Series Analysis.

INTRODUCTION: Rapid outpatient diagnostic programs (RODP) expedite lung cancer evaluation, but their impact on racial disparities in the timeliness of evaluation is less clear. MATERIALS AND METHODS: This was a retrospective analysis of the impact of an internally developed application-supported RODP on racial disparities in timely referral completion rates for patients with potential lung cancer at a safety-net healthcare system. An application screened referrals to pulmonology for indications of lung mass or nodule and presented relevant clinical information that enabled dedicated pulmonologists to efficiently review and triage cases according to urgency. Subsequent care coordination was overseen by a dedicated nurse coordinator. To determine the program's impact, we conducted an interrupted time series analysis of the monthly fraction of referrals completed within 30 days, stratified by those identified as White, non-Hispanic and those that were not (racial and ethnic minorities). RESULTS: There were 902 patients referred in the 2 years preintervention and 913 in the 2 years postintervention. Overall, the median age was 63 years, and 44.7% of referred patients were female. 44.2% were White, non-Hispanic while racial and ethnic minorities constituted 54.3%. After the intervention, there was a significant improvement in the proportion of referrals completed within 30 days (62.4% vs. 48.2%, P <.01). The interrupted time series revealed a significant immediate improvement in timely completion among racial and ethnic minorities (23%, P < .01) that was not reflected in the majority White, non-Hispanic subgroup (11%, not significant). CONCLUSION: A thoughtfully designed and implemented RODP reduced racial disparities in the timely evaluation of potential lung cancer.

A 62-Year-Old Woman With Nodules, Cysts, and Activated Bone Marrow.

CASE PRESENTATION: A 62-year-old woman with a long-term smoking history was evaluated at our lung cancer clinic for a new 2.5-cm lung nodule. She had a history of well-controlled COPD and hypertension. She was in overall good health until 3 weeks before her evaluation in an ED for new-onset exertional dyspnea. Her physical examination was unremarkable, except for diffuse hyperpigmented scaly scalp lesions that coalesced into plaques. Her subjective symptoms were nonproductive cough, exertional dyspnea, unintentional weight loss of 10 lb, and fatigue that had started 2 months earlier. She did not have fever or night sweats.

Critical Illness Secondary to Synthetic Cannabinoid Ingestion.

Importance: Synthetic cannabinoids (SCs), commonly known as K2, spice, or fake weed, are cheap, artificially manufactured recreational drugs that have emerged as a major public health threat in various regions of the US. Objective: To describe the clinical manifestations of SC intoxication. Design, Setting, and Participants: This case series assessed adults admitted to the intensive care unit from 2014 to 2016 with acute life-threatening complications of SC use. Data analysis was completed in October 2016. Exposures: Use of SCs such as K2, spice, or other synthetic versions of cannabinoids. Main Outcomes and Measures: Data collected included patient demographic data, medical history, presenting symptoms, physical findings, laboratory and imaging data, and intensive care unit and hospital course. Results: Thirty patients (mean age, 41 years [range, 21-59 years]; 24 men [80%]) with SC ingestion were admitted to the intensive care unit over a 2-year period. Thirteen patients were undomiciled. The majority had a history of polysubstance abuse, psychiatric illness, or personality disorder. The admission diagnoses were coma (10 patients [33%]), agitation (10 patients [33%]), and seizure (6 patients [20%]). Eighteen patients (60%) had acute respiratory failure, and tracheal intubation was required in 21 patients (70%) for either airway protection or acute respiratory failure. Rhabdomyolysis was noted in 8 patients (26%). A man developed transient cerebral edema with loss of gray-white differentiation but had complete recovery. A woman with history of asthma died of acute respiratory distress syndrome. All patients underwent routine toxicology testing, which was unrevealing in 16 cases and revealed coingestion in the remainder. Sixteen patients (53%) left the hospital against medical advice. Conclusions and Relevance: Ingestion of SCs can lead to life-threatening complications, including severe toxic encephalopathy, acute respiratory failure, and death. Synthetic cannabinoids are undetectable in routine serum and urine toxicology testing but can be suspected on the basis of history and clinical presentation, which may include extreme agitation or coma. Frontline clinicians must be aware of the presentation and be vigilant in suspecting SC intoxication.

Right Heart Thrombi: Patient Outcomes by Treatment Modality and Predictors of Mortality: A Pooled Analysis.

RATIONALE: Right heart thrombi (RiHT) is characterized by the presence of thrombus within the right atrium or right ventricle (RV). Current literature suggests pulmonary embolism (PE) with RiHT carries a high mortality. Guidelines lack recommendations in managing RiHT. We created a pooled analysis on RiHT and report on our institutional experience in managing RiHT. We aimed to evaluate whether patient characteristics and differing treatment modalities predict mortality. METHODS: We created a pooled analysis of case reports and series of patients with RiHT and PE between January 1956 and 2017. We also reviewed a series of consecutive patients with RiHT identified from our institutional PE registry. Age, shock, RV dysfunction, clot mobility, treatment modality, and hospital outcome had to be reported. RESULTS: We identified 316 patients in our pooled analysis. Patients received the following therapies: no treatment 15 (5%), systemic anticoagulation 73 (23%), systemic thrombolysis 108 (34%), surgical embolectomy 101 (32%), catheter-directed therapy 11 (3%), and systemic thrombolysis with surgery 8 (3%). In-hospital mortality was 18.7%. Univariate analysis showed age and shock reduced odds of survival. Multivariate analysis showed shock reduced odds of survival (odds ratios [OR] 0.36, 95% confidence interval [CI]: 0.19-0.72, P ≤ .01) while age, RV dysfunction, and clot-mobility did not affect mortality. In a reduced multivariate analysis adjusting for shock, treatment modality, and clot location alone, systemic thrombolysis increased odds of survival when compared to systemic anticoagulation (OR 2.72, 95% CI: 1.11-6.64, P = .02). Our institutional series identified 18 patients, where in-hospital mortality was 22.2%, 18 (100%) had RV dysfunction, and 5 (28%) had shock. Patients received the following therapies: systemic anticoagulation 8 (44.4%), systemic thrombolysis 4 (22.2%), surgical embolectomy 4 (22.2%), and catheter-directed thrombolysis 2 (11.1%). CONCLUSION: Presence of shock in RiHT is an independent predictor of mortality. Systemic thrombolysis may offer increased odds of survival when compared to systemic anticoagulation. Our findings should be interpreted with caution as they derive from retrospective reports and subject to publication bias.

Physician-initiated daily verbal reminders decrease the duration of indwelling urinary catheter use compared with nurse-initiated reminders.

We compared the effectiveness of physician-initiated daily verbal reminders to primary care providers with nurse-initiated daily verbal reminders in decreasing the duration of inappropriate indwelling urinary catheter use in hospitalized patients. Catheter use duration was significantly decreased in the physician-initiated intervention group compared with the nurse-initiated intervention group (0.5 ± 0.8 vs 1.7 ± 2.7 days, respectively; P = .03).
