    Abstract The mainstay of treatment of venous thromboembolism (VTE) is anticoagulation. Direct oral anticoagulants (DOAC) have revolutionized anticoagulation management, although their efficacy and safety in specialized populations such as antiphospholipid syndrome, advanced renal disease, cancer thrombosis, and geriatric patients remain uncertain. Concerns about bleeding risks of DOACs persist despite reassuring data in the literature and the development of specific antidotes. In this article, the authors present an overview of the basic pharmacology of DOACs and discuss their use in acute VTE, secondary VTE prevention, and specialized VTE patient populations and discuss therapeutic monitoring and reversal in the event of major bleeding.

    Abstract Background: Patient care ownership is essential to delivering high-quality medical care but appears to be eroding among trainees. The lack of an objective measure has limited the study of ownership in physicians.
    Objective: To develop an instrument to measure psychological ownership of patient care.
    Design: Cross-sectional study.
    Participants: Internal medicine trainees in a large, academic hospital completing an inpatient rotation.
    Main measures: Our scale prototype adapted an existing ownership scale (developed in the non-medical setting) based on themes identified in qualitative studies of patient care ownership. We conducted cognitive interviews to determine face validity of the scale items. Our finalized scale measures ownership's key constructs: advocacy, responsibility, accountability, follow-through, knowledge, communication, initiative, continuity of care, autonomy, and perceived ownership. We distributed an online, anonymous, 46-question survey to 219 residents; 192 residents completed the survey; and 166 responses were included in the analysis. We calculated Cronbach's α to determine the scale's internal consistency. Exploratory factor analysis was used to explore possible subscales. We examined construct validity using bivariate and correlational analysis.
    Key results: The 15-item ownership scale demonstrated good internal consistency (Cronbach's α = 0.89). We identified three possible subscales corresponding to assertiveness, being the "go-to" person, and diligence. Training level and prior intensive care unit experience significantly predicted ownership (p < 0.01). There was no significant relationship between ownership and age, gender, inpatient service type, call schedule, patient turnover, or supervisory experience of the attending physician. We found a significant negative correlation between ownership and perceived degree of burnout (r = - 0.33), depression (r = - 0.24), detachment (r = - 0.35), and frustration (r = - 0.31) and a significant positive association between ownership and fulfillment (r = 0.37) and happiness (r = 0.36).
    Conclusion: We developed an instrument to quantify patient care ownership in residents. Our scale demonstrates good internal consistency and preliminary evidence of validity. With further validation, we expect this to be a valuable tool to evaluate interventions aimed at improving ownership.

    Abstract Introduction: Direct oral anticoagulants (DOACs) effectively prevent recurrent venous thromboembolism (VTE). However, it is unknown which agents should be used to prevent recurrent VTE and which patients with unprovoked VTE should receive extended anticoagulation. We therefore sought to compare the efficacy and safety among DOACs for secondary prevention of VTE. We also determined a risk-adapted threshold for initiating extended anticoagulation based on the likelihood of VTE recurrence (without treatment) and bleeding (with treatment) in patients with unprovoked VTE.
    Methods: Our systematic review of randomized controlled trials compares extended anticoagulation with DOACs to another DOAC, aspirin, or placebo for the prevention of recurrent VTE. We searched PubMed, EMBASE, and Cochrane Registry of Controlled Trials (CENTRAL) in October 2018. Our outcomes of interest were VTE recurrence, major bleeding, and all clinically relevant bleeding. We used network meta-analysis to make indirect comparisons among DOACs. We populated the threshold decision-analytic model with data from our meta-analysis to determine the risk of VTE recurrence above which the benefits of extended anticoagulation outweigh the harms compared with no treatment.
    Results: We included four, high-quality, randomized trials comprising 8386 participants. Low-dose apixaban, full-dose apixaban, low-dose rivaroxaban, full-dose rivaroxaban, and dabigatran reduce VTE recurrence compared with placebo (RR = 0.19, 95% CI, 0.12-0.31; RR = 0.20, 95% CI, 0.12-0.32; RR = 0.08, 95% CI, 0.03-0.27; RR = 0.14, 95% CI, 0.06-0.35; RR = 0.19, 95% CI, 0.09-0.40, respectively). No DOACs increased major bleeding risk compared with placebo. A VTE recurrence risk above 0.3% to 0.4% at approximately 1 year is the threshold to treat a patient with unprovoked VTE with extended anticoagulation (with any DOAC).
    Conclusions: All DOACs exhibit comparable efficacy for the prevention of recurrent VTE. Given that the risk of VTE recurrence is much higher than the calculated threshold for treatment, extended thromboprophylaxis should be considered in all patients with unprovoked VTE who do not have increased bleeding risk.

    Abstract Background: Patient care ownership (PCO) is an essential component in medical professionalism and is crucial for delivering high-quality care. The 15-item PCO Scale (PCOS) is a validated questionnaire for quantifying PCO in residents; however, no corresponding tool for assessing PCO in Japan exists. This study aimed to develop a Japanese version of the PCOS (J-PCOS) and validate it among Japanese medical trainees.
    Methods: We performed a multicenter cross-sectional survey to test the validity and reliability of the J-PCOS. The study sample was trainees of postgraduate years 1-5 in Japan. The participants completed the J-PCOS questionnaire. Construct validity was assessed through exploratory and confirmatory factor analyses. Internal consistency reliability was examined by calculating Cronbach's alpha coefficients and inter-item correlations.
    Results: During the survey period, 437 trainees at 48 hospitals completed the questionnaire. Exploratory factor analysis of the J-PCOS extracted four factors: assertiveness, sense of ownership, diligence, and being the "go-to" person. The second factor had not been identified in the original PCOS, which may be related to a unique cultural feature of Japan, namely, a historical code of personal conduct. Confirmatory factor analysis supported this four-factor model, revealing good model fit indices. The analysis results of Cronbach's alpha coefficients and inter-item correlations indicated adequate internal consistency reliability.
    Conclusions: We developed the J-PCOS and examined its validity and reliability. This tool can be used in studies on postgraduate medical education. Further studies should confirm its robustness and usefulness for improving PCO.

    Abstract Immune thrombotic thrombocytopenic purpura (iTTP) is an acquired, fatal microangiopathy if untreated. Randomized controlled trials (RCTs) demonstrated faster time to response with addition of caplacizumab to standard of care (SOC). However, concerns about RCT selection bias and the high cost of caplacizumab warrant examination of all evidence, including real-world observational studies. In this systematic review and meta-analysis, we searched for comparative studies evaluating SOC with or without caplacizumab for the treatment of iTTP. We assessed risk of bias using the Cochrane risk-of-bias-2 tool (RCTs) and the Newcastle-Ottawa Scale (observational studies). The primary efficacy and safety outcomes were all-cause mortality and treatment-emergent bleeding, respectively. Secondary outcomes included exacerbation and relapse, refractory iTTP, and time to response. We included 2 high-quality RCTs and 3 observational studies at high risk of bias comprising 632 total participants. Compared with SOC, caplacizumab was associated with a nonsignificant reduction in the relative risk [RR] of death in RCTs (RR, 0.21; 95% confidence interval [CI], 0.05-1.74) and observational studies (RR, 0.62; 95% CI, 0.07-4.41). Compared with SOC, caplacizumab was associated with an increased bleeding risk in RCTs (RR, 1.37; 95% CI, 1.06-1.77). In observational studies, bleeding risk was not significantly increased (RR, 7.10; 95% CI, 0.90-56.14). Addition of caplacizumab was associated with a significant reduction in refractory iTTP and exacerbation risks and shortened response time but increased relapse risk. Frontline addition of caplacizumab does not significantly reduce all-cause mortality compared with SOC alone, although it reduces refractory disease risk, shortens time to response, and improves exacerbation rates at the expense of increased relapse and bleeding risk.

    Abstract Background: Hospitalist physicians' workload-the total number of patients they care for daily-is rising in the U.S. Hospitalists report that increased workload negatively affects patients care.
    Objective: Measure the associations between hospitalist physicians' workload and clinical outcomes.
    Design, settings, and participants: Observational study, using electronic health record (EHR) data, of adults hospitalized on the hospitalist service at Yale-New Haven Hospital from 2015-2018.
    Main outcome and measures: We defined hospitalists' workload as the number of patients they cared for on the first full hospital day of a given patient's encounter. We used multilevel Poisson and logistic regression to examine associations between workload and length of stay (LOS), return to the Emergency Department (ED), and readmission. We adjusted for sociodemographic factors, patient complexity and severity of illness, and weekend admission (for LOS) or discharge (for ED visits or readmission).
    Results: We analyzed 38,141 hospitalizations. Median patient age was 64 years (IQR 51-78 years), 53% were female, and 34% were nonwhite. Mean workload was 15 patients (SD 3 patients; range 10-34 patients). LOS was prolonged by 0.05 days (95% CI 0.02, 0.08; p(0.001) when comparing the 75th workload percentile (16 patients) to the 25th workload percentile (13 patients). There were no associations between workload and ED visits or readmission within 7 and 30 days.
    Conclusions: There was a statistically significant but modest relationship between workload and LOS; workload was not associated with ED visits or readmissions.Given clinical reports of the deleterious effects of increased hospitalist workload, there is a need for prospective research assessing a range of outcomes, beyond those measurable in contemporary EHR data.
