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.
