Clinician- and Patient-Directed Communication Strategies for Patients With Cancer at High Mortality Risk: A Cluster Randomized Trial.

Importance: Serious illness conversations (SICs) that elicit patients' values, goals, and care preferences reduce anxiety and depression and improve quality of life, but occur infrequently for patients with cancer. Behavioral economic implementation strategies (nudges) directed at clinicians and/or patients may increase SIC completion. Objective: To test the independent and combined effects of clinician and patient nudges on SIC completion. Design, Setting, and Participants: A 2 × 2 factorial, cluster randomized trial was conducted from September 7, 2021, to March 11, 2022, at oncology clinics across 4 hospitals and 6 community sites within a large academic health system in Pennsylvania and New Jersey among 163 medical and gynecologic oncology clinicians and 4450 patients with cancer at high risk of mortality (≥10% risk of 180-day mortality). Interventions: Clinician clusters and patients were independently randomized to receive usual care vs nudges, resulting in 4 arms: (1) active control, operating for 2 years prior to trial start, consisting of clinician text message reminders to complete SICs for patients at high mortality risk; (2) clinician nudge only, consisting of active control plus weekly peer comparisons of clinician-level SIC completion rates; (3) patient nudge only, consisting of active control plus a preclinic electronic communication designed to prime patients for SICs; and (4) combined clinician and patient nudges. Main Outcomes and Measures: The primary outcome was a documented SIC in the electronic health record within 6 months of a participant's first clinic visit after randomization. Analysis was performed on an intent-to-treat basis at the patient level. Results: The study accrued 4450 patients (median age, 67 years [IQR, 59-75 years]; 2352 women [52.9%]) seen by 163 clinicians, randomized to active control (n = 1004), clinician nudge (n = 1179), patient nudge (n = 997), or combined nudges (n = 1270). Overall patient-level rates of 6-month SIC completion were 11.2% for the active control arm (112 of 1004), 11.5% for the clinician nudge arm (136 of 1179), 11.5% for the patient nudge arm (115 of 997), and 14.1% for the combined nudge arm (179 of 1270). Compared with active control, the combined nudges were associated with an increase in SIC rates (ratio of hazard ratios [rHR], 1.55 [95% CI, 1.00-2.40]; P = .049), whereas the clinician nudge (HR, 0.95 [95% CI, 0.64-1.41; P = .79) and patient nudge (HR, 0.99 [95% CI, 0.73-1.33]; P = .93) were not. Conclusions and Relevance: In this cluster randomized trial, nudges combining clinician peer comparisons with patient priming questionnaires were associated with a marginal increase in documented SICs compared with an active control. Combining clinician- and patient-directed nudges may help to promote SICs in routine cancer care. Trial Registration: ClinicalTrials.gov Identifier: NCT04867850.

The Importance of Filter Collection for Accurate Measurement of Cigarette Smoking.

OBJECTIVES: We examined the impact of cigarette filter collection on reports of cigarettes per day (CPD) versus self-reported CPD and to assess the utility of a pre-intervention baseline period in smoking studies. METHODS: Using baseline data from 522 non-treatment seeking smokers, we assessed differences in self-reported CPD via phone screen (CPD PS) and during baseline (CPD BL). We analyzed self-reported cigarette measures to predict carbon monoxide (CO), a measure of smoke exposure. RESULTS: On average, CPD PS was 2.8 CPD more than CPD BL, and reporting multiples of 10 were more often found in CPD PS compared with CPD BL (54.7% vs17.2%, respectively). CPD BL was more strongly associated with CO than self-report CPD. Number of cigarettes smoked today, time since last cigarette, and nicotine dependence were significantly associated with CO. CONCLUSIONS: CPD BL using filter collection is a more accurate measure of cigarette consumption than self-report, which may have implications for assessment of nicotine dependence. When feasible, studies should include a pre-intervention baseline period for comparison data with study outcomes. In addition to CPD BL, studies should assess time since last cigarette and the number of cigarettes smoked today when using CO as a biological measure of smoke exposure.

Systemic infusion and local irrigation with argatroban effective in preventing clot formation during carotid endarterectomy in a patient with heparin-induced thrombocytopenia.

BACKGROUND: A therapeutic dilemma exists when patients with symptomatic carotid stenosis and concomitant heparin-induced thrombocytopenia (HIT) are advised to urgently undergo carotid endarterectomy (CEA) with heparin therapy. METHODS: After a 63-year-old man with HIT and multiple medical comorbidities underwent emergent coronary artery bypass grafting, postoperative imaging revealed plaque at the origin of the left internal carotid artery with 80%-99% stenosis and minimal contralateral internal carotid artery disease. During the patient's evaluation to undergo CEA for symptomatic high-grade carotid stenosis, enzyme-linked immunosorbent assay revealed persistent platelet factor 4 antibodies. RESULTS: The endarterectomy was successfully performed while the patient received argatroban, both as a continuous infusion and intermittent irrigation during dissection of the plaque. Postoperatively, the drip was continued for 24 hours, and the patient was discharged day 2 on a daily dose of 325 mg of aspirin. At the 6-month examination, Doppler ultrasound revealed normal anterograde velocities with no evidence of stenosis, and the patient noted no subsequent ischemic events. CONCLUSIONS: We now recommend systemic intravenous and local argatroban irrigation to prevent thromboembolic complications in CEA cases with HIT and renal insufficiency. Bivalirudin for both systemic intravenous use and local irrigation may be safer in patients without renal insufficiency because of its shorter half-life.

Accuracy of the precordial V-Quick patch in persons with cardiac or pulmonary disease.

The aim of this study was to demonstrate the equivalence of 12-Lead Electrocardiograms (EKG) obtained with the new V-Quick patch and traditional tab-style electrodes. Using a within-subject design, a convenience sample of 100 subjects with either cardiac or pulmonary disease underwent two 12-lead EKGs, one with the traditional tab-style electrodes and one with the precordial patch. Computer-generated measurements of waveform axes and amplitude were obtained for both EKGs. Comparison of mean and 95% confidence intervals revealed no significant differences in Q, R or S wave amplitude across the six precordial leads. Furthermore, a four-factor ANOVA found no significant difference (p > 0.05) in the Q, R and S wave amplitude between the type of electrode, gender and type of disease. A subset of 29 EKGs read by three experts found intra- (.90) and inter-rater (.84) reliability to be strong. In conclusion, the precordial V-Quick patch provided equivalent EKGs to those obtained using standard tab-style electrodes.
