Schizophrenia is associated with a significant economic burden where, in addition to direct health care costs, indirect and non-health care costs are strong contributors, suggesting that therapies should aim at improving not only symptom control but also cognition and functional performance, which are associated with substantial non-health care and indirect costs.

Objective: Brain metastases (BM) are highly prevalent among anaplastic lymphoma kinase positive (ALKþ) non-small cell lung cancer (NSCLC) patients; yet little is known about their real-world treatment patterns and clinical and economic burdens. This study aimed to describe these patients' treatment patterns, symptoms, and costs. Research design and methods:Retrospective study pooling data from three large administrative databases in the US (08/2011-06/2013). ALKþ NSCLC patients with BM and continuous enrollment for ! 60 days before and !30 days after the first observed BM diagnosis were identified by pharmacy records for crizotinib among patients with lung cancer and BM diagnostic codes. Main outcome measures:Treatment patterns, symptoms, healthcare resource utilization, and costs, before and after BM diagnosis. Results:Of the 213 crizotinib patients with BM diagnoses meeting the selection criteria, 23.0% had BM prior to NSCLC diagnosis; 47.4% had BM prior to crizotinib initiation; 19.2% during crizotinib treatment; and 10.3% post-crizotinib treatment. For those diagnosed with BM after NSCLC diagnosis, the median time between the NSCLC and BM diagnoses was 88 days. Following the first observed BM diagnosis, 88.7% used chemotherapy, 63.4% had radiotherapy, and 31.9% had stereotactic radiosurgery. The prevalence of BM-related symptoms substantially increased post-BM-diagnosis: fatigue (from 15% to 39%), headaches (from 5% to 24%), and depression (from 5% to 15%). Monthly costs per patient averaged $5983 before the BM diagnosis and $22,645 after diagnosis. Patients' resource utilization increased significantly post-BM-diagnosis, with a 3-fold increase in OP visits and a 6-fold increase in IP stays. Post-BM-diagnosis costs were driven by pharmacy (42.0%), inpatient (29.6%), and outpatient costs (26.0%). Limitations:The study sample was limited to crizotinib-treated patients. Conclusions:Post-BM-diagnosis, patients experience high symptom burden. Post-BM-diagnosis, treatment is highly variable and costly: average monthly costs per patient almost quadrupled post-BM-diagnosis.312 Burden of brain metastasis in ALKþ lung cancer Gué rin et al.

BackgroundDirect acting antivirals (DAAs) have revolutionized hepatitis C (HCV) treatment with >90% cure rates even in real‐world studies, giving hope that HCV can be eliminated. However, for DAAs to have a population‐level impact on the burden of HCV disease, treatment uptake needs to be expanded. We investigated temporal trends in HCV treatment uptake and evaluated factors associated with second‐generation DAA initiation and efficacy among key HIV‐HCV co‐infected populations in Canada.MethodsThe Canadian HIV‐HCV Co‐Infection Cohort Study prospectively follows 1699 participants from 18 centres. Among HCV RNA+ participants, we determined the incidence of HCV treatment initiation per year overall and by key populations between 2007 and 2015. Key populations were based on World Health Organization (WHO) guidelines including: people who actively inject drugs (PWID) (reporting injection drug use, last 6 months); Indigenous people; women and men who have sex with men (MSM). Multivariate Cox models were used to estimate adjusted hazard ratios (aHR) and 2‐year probability of initiating second‐generation DAAs for each of the key populations.ResultsOverall, HCV treatment initiation rates increased from 8 (95% CI, 6–11) /100 person‐years in 2013 to 28 (95% CI, 23–33) /100 person‐years in 2015. Among 911 HCV RNA + participants, there were 202 second‐generation DAA initiations (93% with interferon‐free regimens). After adjustment (aHR, 95% CI), active PWID (0.60, 0.38–0.94 compared to people not injecting drugs) and more generally, people with lower income (<$18 000 CAD/year) (0.50, 0.35, 0.71) were less likely to initiate treatment. Conversely, MSM were more likely to initiate 1.95 (1.33, 2.86) compared to heterosexual men. In our cohort, the population profile with the lowest 2‐year probability of initiating DAAs was Indigenous, women who inject drugs (5%, 95% CI 3–8%). Not having any of these risk factors resulted in a 35% (95% CI 32–38%) probability of initiating DAA treatment. Sustained virologic response (SVR) rates were >82% in all key populations.ConclusionWhile treatment uptake has increased with the availability of second‐generation DAAs, marginalized populations, already engaged in care, are still failing to access treatment. Targeted strategies to address barriers are needed to avoid further health inequities and to maximize the public health impact of DAAs.

The impact of low-grade AEs on HRQoL should be taken into account, along with other factors, when selecting the optimal treatment for patients newly diagnosed with CML-CP.

Background Data on postoperative outcomes of the COVID-19 patient population is limited. We described COVID-19 patients who underwent a surgery and the pandemic impact on surgical activities. Methods We conducted a multicenter cohort study between March 13 and June 192,020. We included all COVID-19 patients who underwent surgery in nine centres of the Province of Québec, the Canadian province most afflicted by the pandemic. We also included concomitant suspected COVID-19 (subsequently confirmed not to have COVID-19) patients and patients who had recovered from it. We collected data on baseline characteristics, postoperative complications and postoperative mortality. Our primary outcome was 30-day mortality. We also collected data on overall surgical activities during this first wave and during the same period in 2019. Results We included 44 COVID-19 patients, 18 suspected patients, and 18 patients who had recovered from COVID-19 at time of surgery. Among the 44 COVID-19 patients, 31 surgeries (71%) were urgent and 16 (36%) were major. In these patients, pulmonary complications were frequent (25%) and 30-day mortality was high (15.9%). This mortality was higher in patients with symptoms (23.1%) compared to those without symptoms (5.6%), although not statistically significant (p = 0.118). Of the total 22,616 cases performed among participating centres during the study period, only 0.19% had COVID-19 at the time of surgery. Fewer procedures were performed during the study period compared to the same period in 2019 (44,486 cases). Conclusion In this Canadian cohort study, postoperative 30-day mortality in COVID-19 patients undergoing surgery was high (15.9%). Although few surgeries were performed on COVID-19 patients, the pandemic impact on surgical activity volume was important. Trial registration ClinicalTrials.gov Identifier: NCT04458337.

Development of brain metastasis among lung cancer patients is associated with a substantial economic burden to payers, patients, and employers.

After crizotinib monotherapy, most patients either received radiotherapy only or discontinued antineoplastic treatment altogether. OS after discontinuing crizotinib was poor and shorter among those with brain metastases than without, and among those without subsequent antineoplastic treatment than with. Patients who continued antineoplastic treatment incurred substantial healthcare costs.

IntroductionThe prevalence of hepatitis C virus (HCV) is far higher in prison settings than in the general population; thus, micro‐elimination strategies must target people in prison to eliminate HCV. We aimed to examine incarceration patterns and determine whether incarceration impacts HCV treatment uptake among Canadian HIV‐HCV co‐infected individuals in the direct‐acting antiviral (DAA) era.MethodsThe Canadian Co‐Infection Cohort prospectively follows HIV‐HCV co‐infected people from 18 centres. HCV RNA‐positive participants with available baseline information on incarceration history were included and followed from 21 November 2013 (when second‐generation DAAs were approved by Health Canada) until 30 June 2017. A Cox proportional hazards model was used to assess the effect of time‐updated incarceration status on time to treatment uptake, adjusting for patient‐level characteristics known to be associated with treatment uptake in the DAA era.ResultsOverall, 1433 participants (1032/72% men) were included; 67% had a history of incarceration and 39% were re‐incarcerated at least once. Compared to those never incarcerated, previously incarcerated participants were more likely to be Indigenous, earn <$1500 CAD/month, report current or past injection drug use and have poorly controlled HIV. There were 339 second‐generation DAA treatment initiations during follow‐up (18/100 person‐years). Overall, 48% of participants never incarcerated were treated (27/100 person‐years) compared to only 31% of previously incarcerated participants (15/100 person‐years). Sustained virologic response (SVR) rates at 12 weeks were 95% and 92% respectively. After adjusting for other factors, participants with a history of incarceration (adjusted hazard ratio (aHR): 0.7, 95% CI: 0.5 to 0.9) were less likely to initiate treatment, as were those with a monthly income <$1500 (aHR: 0.7, 95% CI: 0.5 to 0.9) or who reported current injection drug use (aHR: 0.7, 95% CI: 0.4 to 1.0). Participants with undetectable HIV RNA (aHR: 2.1, 95% CI: 1.6 to 2.9) or significant fibrosis (aHR: 1.5, 95% CI: 1.2 to 1.9) were more likely to initiate treatment.ConclusionsThe majority of HIV‐HCV co‐infected persons had a history of incarceration. Those previously incarcerated were 30% less likely to access treatment in the DAA era even after accounting for several patient‐level characteristics. With SVR rates above 90%, HCV elimination may be possible if treatment is expanded for this vulnerable and neglected group.
