Real-World Treatment Patterns, Clinical Outcomes, Healthcare Resource Utilization, and Costs in Advanced Hepatocellular Carcinoma in Ontario, Canada.

The therapeutic landscape for aHCC has evolved in recent years, necessitating a comprehensive analysis of treatment patterns, clinical outcomes, HCRU, and costs to contextualize emerging treatments. This study aimed to investigate these outcomes using real-world data from Ontario, Canada. This retrospective cohort study was conducted using linked administrative databases from April 2010 to March 2020. Patients diagnosed with aHCC were included, and their clinical and demographic characteristics were analyzed, as well as treatment patterns, survival, HCRU, and economic burden. Among 7322 identified patients, 802 aHCC patients met the eligibility criteria for inclusion in the study. Treatment subgroups included 1L systemic therapy (53.2%), other systemic treatments (4.5%), LRT (9.0%), and no treatment (33.3%). The median age was 66 years, and the majority were male (82%). The mOS for the entire cohort from diagnosis was 6.5 months. However, patients who received 1L systemic therapy had an mOS of 9.0 months, which was significantly higher than the other three subgroups. The mean cost per aHCC-treated patient was $49,640 CAD, with oral medications and inpatient hospitalizations as the largest cost drivers. The results underscore the need for the continuous evaluation and optimization of HCC management strategies in the era of evolving therapeutic options.

Changes in Health Care Costs, Survival, and Time Toxicity in the Era of Immunotherapy and Targeted Systemic Therapy for Melanoma.

Importance: Melanoma treatment has evolved during the past decade with the adoption of adjuvant and palliative immunotherapy and targeted therapies, with an unclear impact on health care costs and outcomes in routine practice. Objective: To examine changes in health care costs, overall survival (OS), and time toxicity associated with primary treatment of melanoma. Design, Setting, and Participants: This cohort study assessed a longitudinal, propensity score (PS)-matched, retrospective cohort of residents of Ontario, Canada, aged 20 years or older with stages II to IV cutaneous melanoma identified from the Ontario Cancer Registry from January 1, 2018, to March 31, 2019. A historical comparison cohort was identified from a population-based sample of invasive melanoma cases diagnosed from the Ontario Cancer Registry from January 1, 2007, to December 31, 2012. Data analysis was performed from October 17, 2022, to March 13, 2023. Exposures: Era of melanoma diagnosis (2007-2012 vs 2018-2019). Main Outcomes and Measures: The primary outcomes were mean per-capita health care and systemic therapy costs (Canadian dollars) during the first year after melanoma diagnosis, time toxicity (days with physical health care contact) within 1 year of initial treatment, and OS. Standardized differences were used to compare costs and time toxicity. Kaplan-Meier methods and Cox proportional hazards regression were used to compare OS among PS-matched cohorts. Results: A PS-matched cohort of 731 patients (mean [SD] age, 67.9 [14.8] years; 437 [59.8%] male) with melanoma from 2018 to 2019 and 731 patients (mean [SD] age, 67.9 [14.4] years; 440 [60.2%] male) from 2007 to 2012 were evaluated. The 2018 to 2019 patients had greater mean (SD) health care (including systemic therapy) costs compared with the 2007 to 2012 patients ($47 886 [$55 176] vs $33 347 [$31 576]), specifically for stage III ($67 108 [$57 226] vs $46 511 [$30 622]) and stage IV disease ($117 450 [$79 272] vs $47 739 [$37 652]). Mean (SD) systemic therapy costs were greater among 2018 to 2019 patients: stage II ($40 823 [$40 621] vs $10 309 [$12 176]), III ($55 699 [$41 181] vs $9764 [$12 771]), and IV disease ($79 358 [$50 442] vs $9318 [$14 986]). Overall survival was greater for the 2018 to 2019 cohort compared with the 2007 to 2012 cohort (3-year OS: 74.2% [95% CI, 70.8%-77.2%] vs 65.8% [95% CI, 62.2%-69.1%], hazard ratio, 0.72 [95% CI, 0.61-0.85]; P < .001). Time toxicity was similar between eras. Patients with stage IV disease spent more than 1 day per week (>52 days) with physical contact with the health care system by 2018 to 2019 (mean [SD], 58.7 [43.8] vs 44.2 [26.5] days; standardized difference, 0.40; P = .20). Conclusions and Relevance: This cohort study found greater health care costs in the treatment of stages II to IV melanoma and substantial time toxicity for patients with stage IV disease, with improvements in OS associated with the adoption of immunotherapy and targeted therapies. These health system-wide data highlight the trade-off with adoption of new therapies, for which there is a greater economic burden to the health care system and time burden to patients but an associated improvement in survival.

Healthcare and Cancer Treatment Costs of Breast Screening Outcomes among Higher than Average Risk Women.

Concurrent cohorts of 644,932 women aged 50-74 screened annually due to family history, dense breasts or biennially in the Ontario Breast Screening Program (OBSP) from 2011-2014 were linked to provincial administrative datasets to determine health system resource utilization and costs. Age-adjusted mean and median total healthcare costs (2018 CAD) and incremental cost differences were calculated by screening outcome and compared by recommendation using regression models. Healthcare costs were compared overall and 1 year after a false positive (n = 46,081) screening mammogram and 2 years after a breast cancer diagnosis (n = 6011). Mean overall healthcare costs by age were highest for those 60-74, particularly with annual screening for family/personal history (CAD 5425; 95% CI: 5308 to 5557) compared to biennial. Although the mean incremental cost difference was higher (23.4%) by CAD 10,235 (95% CI: 6141 to 14,329) per breast cancer for women screened annually for density ≥ 75% compared to biennially, the cost difference was 12.0% lower (-CAD 461; 95% CI: -777 to -114) per false positive result. In contrast, for women screened annually for family/personal history, the mean cost difference per false positive was 19.7% higher than for biennially (CAD 758; 95% CI: 404 to 1118); however, the cost difference per breast cancer was only slightly higher (2.5%) by CAD 1093 (95% CI: -1337 to CAD 3760). Understanding that associated costs of annual compared to biennial screening may balance out by age and outcome can assist decision-making regarding the use of limited healthcare resources.

Hospital encounters and associated costs of prostate evaluation for clinically important disease MRI vs. standard evaluation procedures (PRECISE) study from a provincial-payer perspective.

INTRODUCTION: Systematic transrectal ultrasonography (TRUS) biopsy has been the standard diagnostic tool for prostate cancer (PCa) but is subject to limitations, such as a high false-negative rate of cancer detection. Multiparametric magnetic resonance imaging (mpMRI) prior to biopsy is emerging as an alternative diagnostic procedure for PCa. The PRECISE study found that MRI followed by a targeted biopsy was more accurately able to identify clinically significant cancer than TRUS biopsy. METHODS: PRECISE study patients recruited in Ontario between January 2017 and November 2019 were linked to various Ontario provincial administrative databases available at the Institute for Clinical and Evaluative Sciences (ICES ) to determine health resources used, associated costs, and hospitalizations in the 14 days after biopsy. Costs are presented in 2021 CAD. RESULTS: A total of 281 males were included in this study, with 48.4% of the patients in the TRUS biopsy group, 28.1% in the MRI+, and 23.5% in the MRI- group. Twenty-one patients (15%) from the TRUS biopsy group were seen at a hospital in the 14 days after their biopsy compared to fewer than five patients (6%) from the MRI+ group. The mean per person per year (PPPY) costs for the TRUS and all MRI groups (MRI- and MRI+) were $7828 and $8525, respectively. CONCLUSIONS: Patients in the TRUS biopsy group experienced more hospital encounters compared to patients who received an MRI prior to their biopsy. This economic analysis suggests that MRI imaging prior to biopsy is not associated with a significant increase in costs.

Using Real-World Data to Determine Health System Costs of Ontario Women Screened for Breast Cancer.

Our study was to determine breast cancer screening costs in Ontario, Canada for screenings conducted through a formal (Ontario Breast Screening Program, OBSP) and informal (non-OBSP) screening program using administrative databases. Included women were 49-74 years of age when receiving screening mammograms between 1 January 2013 to 31 December 2019. Each woman was followed for a screening episode with screening and diagnostic components, and costs were calculated as an average cost per woman per month in 2021 Canadian dollars. The final cohort of 1,546,386 women screened had a mean age of 59.4 ± 7.1 years and ~87% were screened via OBSP. The average total cost per woman per month was $136 ± $103, $134 ± $103 and $155 ± $104 for the entire, OBSP and non-OBSP cohorts, respectively. This was further disaggregated into the average total screening cost per month, which was $103 ± $8, $100 ± $4 and $117 ± $9 per woman, and the average total diagnostic cost per woman per month at $219 ± $166, $228 ± $165 and $178 ± $159. for the entire, OBSP and non-OBSP cohorts, respectively. These results indicate similar screening costs across the different cohorts, but higher diagnostic costs for the OBSP cohort.

Real-World Treatment Patterns, Survival, and Costs for Ovarian Cancer in Canada: A Retrospective Cohort Study Using Provincial Administrative Data.

Background: In 2020, approximately 3100 Canadian women were diagnosed with ovarian cancer (OC), with 1950 women dying of this disease. Prognosis for OC remains poor, with 70% to 75% of cases diagnosed at an advanced stage and an overall 5-year survival of 46%. Current standard of care in Canada involves a combination of cytoreductive surgery and platinum-based chemotherapy. Objective: There are few studies reporting current OC costs. This study sought to determine patient characteristics and costs to the health system for OC in Ontario, Canada. Methods: Women diagnosed with OC in Ontario between 2010 and 2017 were identified. The cohort was linked to provincial administrative databases to capture treatment patterns, survival, and costs. Overall total and mean cost per patient (unadjusted) were reported in 2017 Canadian dollars, using a macro-based costing methodology called GETCOST. It is programmed to determine the costs of short-term and long-term episodes of health-care resources utilized. Results: Of the 2539 OC patients included in the study, the mean age at diagnosis was 60.4±11.35 years. The majority were diagnosed with stage III disease (n=1247). The only treatment required for 74% of stage I patients and 54% of stage II patients was first-line (1L) platinum chemotherapy; in advanced stages (III/IV) 24% and 20%, respectively, did not receive further treatment after 1L therapy. The median overall survival (mOS) for the whole cohort was 5.13 years. Survival was highest in earlier stage disease (mOS not reached in stage I/II), and dropped significantly in advanced stage patients (stage III: mOS=4.09 years; stage IV: mOS=3.47 years). Overall mean costs in patients stage I were CAD $58 099 compared to CAD $124 202 in stage IV. Discussion: The majority of OC patients continue to be diagnosed with advanced disease, which is associated with poor survival and increased treatment costs. Increased awareness and screening could facilitate diagnosis of earlier stage disease and reduce high downstream costs for advanced disease. Conclusion: Advanced OC is associated with poor survival and increased costs, mainly driven by hospitalizations or cancer clinic visits. The introduction of new targeted therapies such as olaparib could impact health system costs, by offsetting higher downstream costs while also improving survival.

Health system costs for cancer medications and radiation treatment in Ontario for the 4 most common cancers: a retrospective cohort study.

BACKGROUND: Previous costing and resource estimates for cancer have not been complete owing to lack of comprehensive data on cancer-related medication and radiation treatment. Our objective was to calculate the mean overall costs per patient of cancer-related medications and radiation, as well as by disease subtype and stage, in the first year after diagnosis for the 4 most prevalent cancers in Ontario. METHODS: We conducted a retrospective cohort study using provincial health administrative databases to identify population health system resources and costs for all patients diagnosed with breast, colorectal, lung or prostate cancer between Jan. 1, 2010, and Dec. 31, 2015 in Ontario. The primary outcome measure was the overall average cost per patient in the 365 days after diagnosis for cancer-related medications and radiation treatment, calculated with the use of 2 novel costing algorithms. We determined the cost by disease, disease subtype and stage as secondary outcomes. RESULTS: There were 168 316 Ontarians diagnosed with cancer during the study period, 50 141 with breast cancer, 38 108 with colorectal cancer, 34 809 with lung cancer and 45 258 with prostate cancer. The mean per-patient cost for cancer-related medications was $8167 (95% confidence interval [CI] $8023-$8311), $6568 (95% CI $6446-$6691), $2900 (95% CI $2816-$2984) and $1211 (95% CI $1175-$1247) for breast, colorectal, lung and prostate cancer, respectively. The corresponding mean radiation treatment costs were $18 529 (95% CI $18 415-$18 643), $15 177 (95% CI $14 899-$15 456), $10 818 (95% CI $10 669-$10 966) and $16 887 (95% CI $16 648-$17 125). In general, stage III and IV cancers were the most expensive stages for both medications and radiation across all 4 disease sites. INTERPRETATION: Our work updates previous costing estimates to help understand costs and resources critical to health care system planning in a single-payer system. More refined costing estimates are useful as inputs to allow for more robust health economic modelling and health care system planning.

Assessing the Impact of Early Identification of Patients Appropriate for Palliative Care on Resource Use and Costs in the Final Month of Life.

PURPOSE: This study evaluates whether an intervention to identify Canadian patients eligible for a palliative approach changes the use of health care resources and costs within the final month of life. METHODS: Between 2014 and 2017, physicians identified 1,187 patients in family practice units and cancer centers who were likely to die within 1 year based on diagnosis, symptom assessment, and performance status. A multidisciplinary intervention that included activation of community resources and initiation of palliative planning was started. By using propensity-score matching, patients in the intervention group were matched 1:1 with nonintervention controls selected from provincial administrative data. We compared health care use and costs (using 2017 Canadian dollars) for 30 days before death between patients who died within the 1-year follow-up and matched controls. RESULTS: Groups (n = 629 in each group) were well-balanced in sociodemographic characteristics, comorbidities, and previous health care use. In the last 30 days, there was no differences in proportions between the two groups of patients regarding emergency department visits, intensive care unit admissions, or inpatient hospitalizations. However, patients in the intervention group had greater use of palliative physician encounters, community home care visits, and/or physician home visits (92.8% v 88.4%; P = .007). In the 507 pairs with cancer, more patients in the intervention group underwent chemotherapy (44% v 33%; P < .001) and radiation (18.7% v 3.2%; P = .043) in the last 30 days. Mean cost per patient was similar for the intervention group (mean, $17,231; 95% CI, $16,027 to $18,436) and for the control group (mean, $16,951; 95% CI, $15,899 to $18,004). CONCLUSION: Even with the limitations in our observational study design, identification of palliative patients did not significantly change overall costs but may shift resources toward palliative services.

Demographic characteristics and cost of treatment among oncology patients in a publicly funded system, the Ontario Trillium Drug Program: a retrospective cohort study.

BACKGROUND: The aim of this study was to characterize the demographic characteristics and investigate the cost of a publicly funded system, the Ontario Trillium Drug Program (TDP), for an oncology patient population. METHODS: We ascertained all TDP claims between April 1997 and December 2016 from the Ontario Drug Benefit database to assess use and cost. Each drug was classified as a cancer treatment drug, cancer supportive therapy drug or noncancer drug. We also identified a cohort of patients with cancer with least 1 TDP claim, for whom we examined demographic and claims-related characteristics. RESULTS: Over the study period, 50 975 293 TDP claims totalling $4.8 billion were made. Although the proportion of cancer claims among all TDP claims remained constant between 1997 and 2016, the total annual cost of cancer treatment drugs increased nearly 40-fold. Imatinib and lenalidomide together accounted for nearly half of the cost of all cancer treatment drugs. We identified a cohort of 49 892 patients with cancer, of whom 18 631 (37.3%) were enrolled in the TDP before their cancer diagnosis and 31 261 (62.7%) were enrolled after their diagnosis. The former were more likely than the latter to be in lower income quintiles and to have more chronic conditions. Significant differences were also found in the distribution of cancer diagnoses between the 2 groups. INTERPRETATION: In the TDP, use increased over time and differed across cancer diagnoses and drugs. These results have public health and policy implications as antineoplastic drug costs continue to rise and place a burden on patients.

Examination of Health System Resources and Costs Associated With Transitioning Cancer Survivors to Primary Care: A Propensity-Score-Matched Cohort Study.

BACKGROUND:: Transitioning low-risk cancer survivors back to their primary care provider (PCP) has been shown to be safe but the effect on health system resources and costs has not been examined. METHODS:: A Well Follow-Up Care Initiative (WFCI) was implemented in the publicly funded health system. Low-risk breast cancer (BC) survivors in the WFCI intervention group were transitioned from oncologist-led cancer clinics to PCPs. We compared health system costs ($2,014 in Canadian dollars) and resource utilization in this intervention group with that in propensity-score-matched nontransitioned BC survivors (ie, controls) diagnosed in the same year, with similar disease profile and patient characteristics using publicly funded administrative databases. RESULTS:: A total of 2,324 BC survivors from the WFCI intervention group were 1:1 matched to controls and observed for 25 months. Compared with controls, survivors in the intervention group incurred a similar number of PCP visits (6.9 v 7.5) and fewer oncologist visits (0.3 v 1.2) per person-year. Fewer survivors in the intervention group (20.1%) were hospitalized than in the control group (24.4%). There were no differences in emergency visits. More survivors in the intervention group had mammograms (82.6% v 73.1%), but other diagnostic tests were less frequent. There was a 39.3% reduction in overall mean annual costs ($6,575 v $10,832) and a 22.1% reduction in overall median annual costs ($2,261 v $2,903). Overall survival in the intervention group was not worse than controls. CONCLUSION:: Transitioning low-risk BC survivors to PCPs was associated with lower health system resource use and a lower annual cost per patient than matched controls. The WFCI model represents a reasonable approach at the population level to delivering quality care for low-risk BC survivors that seems to be cost effective.

Population-Based Study to Determine the Health System Costs of Using the 21-Gene Assay.

Purpose The 21-gene assay Oncotype Dx (Genomic Health, Redwood City, CA) test is used to aid the decision about chemotherapy in patients with hormone receptor-positive breast cancer who received endocrine therapy. Economic studies to support test adoption used decision-analytic models with assumptions and data derived from disparate sources. The objective was to evaluate whether the 21-gene assay test resulted in an overall cost expense or saving to the health system. Patients and Methods One thousand participants enrolled in a field evaluation study, were linked to population-level health system administrative databases, and were observed for 20 months. The cost for the cohort, which included the cost of the test, subsequent treatments received, and health care encounters, was determined. The cost in the absence of the test was compared with the pretest recommendation about chemotherapy from the field study for a base case and under scenarios that reflected different adjuvant chemotherapy use. Overall health system costs and incremental costs were calculated. Results The 21-gene assay resulted in a net decrease in chemotherapy use of 23%. For the base case incremental analysis, the actual overall health system cost of this cohort, including the cost of 21-gene assay, was $29.2 million compared with $26.2 million in the absence of the test-an increase of $3.1 million. For three of the four scenario analyses, the actual overall cost to the health system exceeded the estimated cost in the absence of the test. Results showed that, when at least half of the population received adjuvant chemotherapy, the cost increased to $30.2 million. Conclusion The use of real-world administrative data showed that, despite lower rates of chemotherapy use, the 21-gene assay test results in an overall incremental cost to the health care system in the short-term under most assumptions.

EQ-5D Health Utility Scores: Data from a Comprehensive Canadian Cancer Centre.

BACKGROUND: To improve the precision of health economics analyses in oncology, reference datasets of health utility (HU) scores are needed from cancer survivors across different disease sites. These data are particularly sparse amongst Canadian survivors. METHODS: A survey was completed by 1759 ambulatory cancer survivors at the Princess Margaret Cancer Centre which contained demographic questions and the EuroQol-5D (EQ-5D) instrument. Clinical information was abstracted from electronic records and HU scores were calculated using Canadian health state valuations. Construct validity was assessed through correlation of HU and visual analog scale (VAS) scores (Spearman) and by comparing HU scores between performance status groups (effect size). The influence of socio-demographic clinical variables on HU was analyzed by non-parametric between-group comparisons and multiple linear regression. RESULTS: Mean EQ-5D HU scores were derived for 26 cancers. Among all survivors, the mean ± standard error of the mean EQ-5D utility score was 0.81 ± 0.004. Scores varied significantly by performance status (p < 0.0001) and correlated with VAS (Spearman r = 0.61). The cancer sites with the lowest mean HU scores were acute lymphoblastic leukemia (0.70 ± 0.03) and pancreatic cancer (0.76 ± 0.03); testicular cancer (0.89 ± 0.02) and chronic lymphocytic leukemia (0.90 ± 0.05) had the highest mean scores. A multiple regression model showed that scores were influenced by disease site (p < 0.001), education level (p < 0.001), partner status (p < 0.001), disease extent (p = 0.0029), and type of most recent treatment (p = 0.0061). CONCLUSIONS: This work represents the first set of HU scores for numerous cancer sites derived using Canadian preference weights. The dataset demonstrated construct validity and HU scores varied by general socio-demographic and clinical parameters.

Phase-specific healthcare costs of cervical cancer: estimates from a population-based study.

BACKGROUND: There is a lack of evidence on the economic burden of managing cervical cancer in the public payer Canadian setting. OBJECTIVE: We used individual patient-level data to obtain a comprehensive estimate of the cost of managing cervical cancer in the province of Ontario, identifying main cost drivers and predictors of increased costs. STUDY DESIGN: The cost-of-illness technique was used to estimate the incremental costs associated with cervical cancer in 4 phases: prediagnosis, initial care, continuing care, and terminal care. All patients with cervical cancer diagnosed between 2005 and 2009 in the province of Ontario were propensity-score matched to 5 noncancer controls on birth year, income quintile, rurality, comorbidities, and patterns of healthcare utilization pattern during the 2 years before cancer diagnosis. Both cases and the noncancer comparison group were followed to death or March 31, 2013. Costs for all healthcare services paid for by the Ontario Ministry of Health and Long-term Care during the follow-up period were estimated by the use of linked administrative data. Incremental costs for managing cervical cancer were calculated through generalized estimating equations. Predictors of greater health costs were explored using multivariate quantile regression models. RESULTS: All costs were presented in 2012 Canadian dollars ($1.00CDN = $1.00USD). The total incremental costs for managing cervical cancer were $362 in the pre-diagnosis phase, $15,722 in the initial phase, $3924 per year in the continuing phase, and $52,539 in the terminal phase. Inpatient care accounted for 34%, 28%, and 52% of total healthcare cost in the initial, continuing, and terminal phase, respectively. Physician services ranked first in the continuing phase (30%) and second in the initial (26%) and terminal (13%) phases. Advanced age, advanced cancer stage at diagnosis, and comorbidities were significant predictors of greater costs in most care phases. CONCLUSION: Aggregate costs of care for cervical cancer are substantial and vary by cancer stage, phase of care, patient age at diagnosis, and comorbidities before diagnosis. These estimates can serve as baseline data in economic analyses that aim to evaluate interventions for managing cervical cancer.

Impact of aggressive management and palliative care on cancer costs in the final month of life.

BACKGROUND: A significant share of the cost of cancer care is concentrated in the end-of-life period. Although quality measures of aggressive treatment may guide optimal care during this timeframe, little is known about whether these metrics affect costs of care. METHODS: This study used population data to identify a cohort of patients who died of cancer in Ontario, Canada (2005-2009). Individuals were categorized as having received or having not received aggressive end-of-life care according to quality measures related to acute institutional care or chemotherapy administration in the end-of-life period. Costs (2009 Canadian dollars) were collected over the last month of life through the linkage of health system administrative databases. Multivariate quantile regression was used to identify predictors of increased costs. RESULTS: Among 107,253 patients, the mean per-patient cost over the final month was $18,131 for patients receiving aggressive care and $12,678 for patients receiving nonaggressive care (P < .0001). Patients who received chemotherapy in the last 2 weeks of life also sustained higher costs than those who did not (P < .0001). For individuals receiving end-of-life care in the highest cost quintile, early and repeated palliative care consultation was associated with reduced mean per-patient costs. In a multivariate analysis, chemotherapy in the 2 weeks of life remained predictive of increased costs (median increase, $536; P < .0001), whereas access to palliation remained predictive for lower costs (median decrease, $418; P < .0001). CONCLUSIONS: Cancer patients who receive aggressive end-of-life care incur 43% higher costs than those managed nonaggressively. Palliative consultation may partially offset these costs and offer resultant savings.

Utilization and costs of home care for patients with colorectal cancer: a population-based study.

BACKGROUND: The utilization and costs of home care services provided for people with colorectal cancer is not well-known. We conducted an analysis to determine the utilization and costs of such services associated with each stage of colorectal cancer among patients in the province of Ontario. METHODS: We included cases of colorectal cancer diagnosed in Ontario between Jan. 1, 2005, and Dec. 31, 2009. Data were extracted from the Ontario Cancer Registry and linked to data from a home care administrative database. The types of services used were stratified by stage of disease and by phase of care (initial phase = 180 d after diagnosis, terminal phase = 180 d before death, continuing phase = interval between initial and terminal phases). Overall utilization rates and costs were determined, and regression analysis was used to examine associated factors. RESULTS: A total of 36 195 patients had colorectal cancer diagnosed during the study period; the median age was 71 (interquartile range 61-79) years. Home care services were provided to 24 641 patients (68.1%). The number of services per patient-year was 27.5, at a cost of $2180 per patient-year. The number of services provided per patient-year increased with increasing disease severity at diagnosis (15.5 at stage I, 25.5 at stage II, 32.5 at stage III and 62.5 at stage IV; 22.6 for unstaged disease). The cost of services per patient-year also increased with disease severity at diagnosis ($1170 at stage I, $1995 at stage II, $2727 at stage III and $5541 at stage IV). Publicly funded home care services and associated costs decreased with increasing income group, but they increased among patients who had a history of high health resource utilization. The mean 30-day cost of home care services decreased from the initial phase of care ($323) to the continuing phase ($160) but increased during the terminal phase ($616). INTERPRETATION: More than two-thirds of the patients with colorectal cancer in this study used home care services. Those who received home care services used about 2 services per month in a one-year period, at a cost of about $2000 per year. This information can aid policy-makers in future decisions regarding resource allocations.

Impact of disability status on ischemic stroke costs in Canada in the first year.

BACKGROUND: Longitudinal, patient-level data on resource use and costs after an ischemic stroke are lacking in Canada. The objectives of this analysis were to calculate costs for the first year post-stroke and determine the impact of disability on costs. METHODOLOGY: The Economic Burden of Ischemic Stroke (BURST) Study was a one-year prospective study with a cohort of ischemic stroke patients recruited at 12 Canadian stroke centres. Clinical history, disability, health preference and resource utilization information was collected at discharge, three months, six months and one year. Resources included direct medical costs (2009 CAN$) such as emergency services, hospitalizations, rehabilitation, physician services, diagnostics, medications, allied health professional services, homecare, medical/assistive devices, changes to residence and paid caregivers, as well as indirect costs. Results were stratified by disability measured at discharge using the modified Rankin Score (mRS): non-disabling stroke (mRS 0-2) and disabling stroke (mRS 3-5). RESULTS: We enrolled 232 ischemic stroke patients (age 69.4 ± 15.4 years; 51.3% male) and 113 (48.7%) were disabled at hospital discharge. The average annual cost was $74,353; $107,883 for disabling strokes and $48,339 for non-disabling strokes. CONCLUSIONS: An average annual cost for ischemic stroke was calculated in which a disabling stroke was associated with a two-fold increase in costs compared to NDS. Costs during the hospitalization to three months phase were the highest contributor to the annual cost. A "back of the envelope" calculation using 38,000 stroke admissions and the average annual cost yields $2.8 billion as the burden of ischemic stroke.

A strategy to offset the extra cost of sirolimus-eluting stent in patients undergoing intervention for acute myocardial infarction.

OBJECTIVE: To obtain a quantitative estimate of the overall costs and cost effectiveness ratio of sirolimus-eluting stents (SES) implantation and tirofiban infusion compared to abciximab and bare metal stent (BMS) in patients undergoing primary intervention for acute ST segment elevation myocardial infarction (STEMI). METHODS: In the attempt to make the unrestricted use of SES in STEMI patients affordable under the current European reimbursement system, between March 6, 2003, and April 23, 2004, 175 patients with STEMI were randomized to receive tirofiban infusion and SES versus abciximab and BMS as part of the STRATEGY trial. Costs and outcome were monitored for 2 years. RESULTS: The cost of the index procedure was 9345 euros +/-2573 and 9657+/-2114 for the tirofiban+SES and abciximab+BMS group, respectively (P=0.048). At follow-up, the composite of death or myocardial infarction and the costs not related to target vessel revascularisation (TVR) did not differ in the two groups while the rate of TVR and the costs related to it were lower in the tirofiban+SES group. The overall 2-year cost of treating a patient in the tirofiban+SES group was 10,971 euros +/-4185 compared to 12,066 euros +/-4636 for the abciximab+BMS group (P=0.006). Halving the cost of abciximab resulted in higher initial hospital costs for the tirofiban+SES but overall cost neutrality over a 24-month time horizon. CONCLUSIONS: Compared to abciximab+BMS, tirofiban infusion+SES implantation in STEMI patients was an economically dominant strategy, with an improved composite outcome and lower overall costs.

Urgent care costs of uncontrolled asthma in Canada, 2004.

It has been more than a decade since Krahn evaluated the direct and indirect costs of asthma in Canada. Asthma is often uncontrolled and the cost of providing urgent care has not been determined. Hospitalizations, unscheduled physician visits, emergency department visits, drug treatments and ambulance rides are resources used by the uncontrolled asthmatic population, resulting in 162 million US dollars in costs annually. Improved control of asthma could decrease these costs.

The economics of adjunctive therapies in coronary angioplasty: drugs, devices, or both?

BACKGROUND: Abciximab reduces the number of ischemic events in patients undergoing angioplasty compared to standard therapy. Coronary stenting reduces the need for repeat procedures. Abciximab or stents individually are considered cost effective interventions. There is a need to quantify the economic value of the combination of abciximab and stenting over stenting alone. METHODS: A decision analytic model was developed incorporating the outcomes from the EPISTENT study. Costs from Canadian sources for hospitalization, procedures and medications were used. Life expectancy was estimated using a Markov model. Total expected costs and outcomes of the abciximab and stent vs. stent alone were compared in an incremental analysis. The perspective of the analysis was a Canadian teaching hospital. RESULTS: The acquisition cost for abciximab was partially offset by reduced costs for managing clinical events resulting in a net incremental cost of 1,076 dollars per patient over one year (8,617 dollars combination vs. 7,541 dollars stent alone). This added cost was accompanied by a reduction in large MI or death by an absolute rate of 5.7% at one year (5.3% combination vs. 11.0% stent alone), yielding an incremental cost-effectiveness ratio of 18,877 dollars per death or large MI averted. The long-term survival gain was 0.15 to 0.37 years yielding an attractive incremental cost effectiveness ratio of 2,832 dollars to 7,173 dollars per life year gained. CONCLUSIONS: The combination of abciximab and stenting versus stenting alone provides improved clinical outcomes at a very reasonable cost from the Canadian hospital perspective.
