Are we choosing wisely? Operationalizing Choosing Wisely in the Ontario cancer system

221

Background: The Choosing Wisely (CW) campaign aims to initiate conversations about unnecessary treatments contributing to the rising cost of cancer care. We aim to develop a data linkage research platform to operationalize CW recommendations within administrative health care databases and the population-based performance of these recommendations. We initiated testing with the CW recommendiation against routine surveillance imaging in patients with aggressive histology lymphoma and pancreatic/gastric (P/G) cancer treated with curative intent. Methods: We used population-based administrative databases from Ontario, Canada to examine a cohort of adult patients with diffuse large B-cell lymphoma (DLBCL) (2004-2011) and P/G cancer post-surgical resection (2003-2013). For the DLBCL cohort, we defined an index date of 2-years after the last dose of R-CHOP as the time-frame beyond which surveillance CT imaging would be inappropriate. For the P/G cohort, the index date was 6 months post-resection. The primary outcome was cumulative incidence of CT scans within 3 years of the index date. To ensure that only surveillance scans were captured, we censored 6 months prior to development of recurrent disease, a new cancer diagnosis, or death. Results: The cohort consisted of 2,838 DLBCL and 2,930 P/G patients. The cumulative incidence of receiving CT imaging in the three years post index date was 55.6% (95% CI 53.7%-57.5%) among DLBCL and 82.8% (95% CI 81.3%-84.3%) among P/G patients. DLBCL patients ≥65 were more likely to receive imaging (p<0.01) as were those with more comorbidities (p<0.01). Younger patients with P/G were more likely to receive imaging (p<0.01) as were men (p<0.01). Income and rurality did not predict for increased imaging in either cohort. Surveillance CT imaging decreased over time among DLBCL patients (p<0.01), but increased among P/G cancer patients (p<0.001). Conclusions: During a time-frame in which surveillance imaging is deemed unnecessary by the CW campaign, the practice in Ontario remains excessive. This study represents a real-world demonstration that CW statements can be operationalized within population-based administrative databases and used as quality indicators in cancer care.

The implementation of a streamlined process for biomarker testing in medical oncology

179

Background: Biomarker testing is increasingly becoming an essential part of standard care. At Sunnybrook Health Sciences Centre (SHSC) in Toronto, Canada, our Department of Molecular Services handles some internal biomarker tests, while some tests are referred to citywide labs. The Odette Cancer Centre (OCC) of SHSC is one of the largest cancer centres in Canada, serving over 12,000 new patients per year, of whom many rely on biomarker tests for personalized treatment. We aimed to describe the work systems at the OCC for biomarker testing and reporting, and to initiate system improvements. Methods: This quality improvement initiative occurred in three phases: qualitative descriptive analysis of the current process of biomarker testing, exploration of future state process using LEAN, and implementation of a streamlined process. In phase one, ten medical oncologists, two administrative assistants, and one pathologist were interviewed. A multidisciplinary team was then assembled to investigate and initiate improvements. Results: Tracking results from external labs was managed by individual physicians and hard copy results were submitted to medical records for filing in patient paper charts, compared to internal tests which are posted on the electronic record, making outside tests harder to retrieve later. The current process involved more than 150 different tests with only 44% of results appearing in the hospital electronic record. In June 2016, a standardized process was implemented where a designated laboratory assistant managed requisition forms, sent corresponding specimens to qualified labs, ensured the receipt of results through various electronic tracking tools and validated the subsequent upload to the electronic medical system. Over a four-month implementation period, there were 364 cases/patients with 467 tests requested; 100% of these test results are stored in the electronic record. Conclusions: The lack of standardization of biomarker testing and reporting can have negative implications on quality of care and patient safety. Therefore, streamlining this process and incorporating electronic tracking tools can improve the accessibility of test results to improve the quality of oncology care.

Examining the medical resource utilization and costs of relapsed and refractory chronic lymphocytic leukemia in Ontario

PURPOSE

The purpose of the present study was to collect medical resource utilization data and costs in Ontario for the management of patients with relapsed or refractory chronic lymphocytic lymphoma (cll) who have undergone at least 1 treatment course and have been stratified by Rai staging.

METHODS

This retrospective longitudinal cohort study, conducted by chart review, analyzed anonymized patient records from two cancer centres in Ontario. Comprehensive records of 86 patients meeting the inclusion criteria were used to obtain resource utilization, which, multiplied by unit costs, were used to determine overall and mean costs. Descriptive statistics are presented for patient demographics, medical resource utilization, and costing data.

RESULTS

The total cost for the cohort was $2.2 million over a mean follow-up period of 4.7 years. The mean total cost per patient (regardless of follow-up) was $25,736. In terms of Rai staging, overall mean costs were highest for stage iv patients. Almost 50% of the total cost was attributable to cll treatments, among which fludarabine-based treatments had the highest utilization.

CONCLUSIONS

For this Canadian cll cohort, medical resource utilization and costs were determined to be $2.2 million, with cll treatments accounting for about half the cost. Costs generally increased with Rai stage.

Comparing assessment frameworks for cancer drugs between Canada and Europe: What can we learn from the differences?

The increasing burden of costs associated with novel cancer therapies is becoming untenable. In Europe and Canada, assessment frameworks have been developed to attribute value to novel therapies and ultimately facilitate access to cancer drug funding. A review of the two frameworks has not previously been undertaken. This review provides insight into the relative strengths and benefits of each approach, the various perspectives of value (patient, physician and societal) and how the frameworks relate to their unique context and core principles. Both frameworks assess the clinical benefit of a new cancer therapy. The European framework considers effectiveness, quality of life, and toxicity in its determination of benefit and has the advantage of providing a simple summary score to facilitate priority setting. The Canadian framework considers other elements including cost-effectiveness, patient preferences and adoption feasibility; its deliberative framework precludes a simple summative presentation of value but can address complex and nuanced drug funding considerations with flexibility. Both frameworks have evolved to meet the needs unique to their jurisdictions and offer potentially complementary tools in the assessment of new cancer drugs. Lessons learnt in both systems can be applied to future iterations of the frameworks, which remain works in progress.

The experiences of cancer survivors while transitioning from tertiary to primary care

PURPOSE

In current fiscally constrained health care systems, the transition of cancer survivors to primary care from tertiary care settings is becoming more common and necessary. The purpose of our study was to explore the experiences of survivors who are transitioning from tertiary to primary care.

METHODS

One focus group and ten individual telephone interviews were conducted. Data saturation was reached with 13 participants. All sessions were audio-recorded, transcribed verbatim, and analyzed using a qualitative descriptive approach.

RESULTS

Eight categories relating to the main content category of transition readiness were identified in the analysis. Several factors affected participant transition readiness: how the transition was introduced, perceived continuity of care, support from health care providers, clarity of the timeline throughout the transition, and desire for a "roadmap." Although all participants spoke about the effect of their relationships with health care providers (tertiary, transition, and primary care), their relationship with the primary care provider had the most influence on their transition readiness.

CONCLUSIONS

Our study provided insights into survivor experiences during the transition to primary care. Transition readiness of survivors is affected by many factors, with their relationship with the primary care provider being particularly influential. Understanding transition readiness from the survivor perspective could prove useful in ensuring patient-centred care as transitions from tertiary to primary care become commonplace.

End-of-life home care utilization and costs in patients with advanced colorectal cancer

OBJECTIVE

To determine overall utilization and costs associated with home care services in Ontario, Canada by linking a home care database to a stage IV colorectal cancer cohort.

METHODS

The names of patients with stage IV colorectal cancer at time of diagnosis (diagnosed from 2005 through 2009) were extracted from the Ontario Cancer Registry. The study cohort comprised those who died before the end of the study. The terminal phase of care was the period of time between diagnosis and death, with a maximum value of 180 days (6 months). Patients were linked to home care services datasets. The type, frequency, and cost of home care services were determined. Regression analysis was used to examine factors associated with utilization and cost.

RESULTS

In all, 3,613 stage IV colorectal cancer patients (median age, 71 years) were diagnosed and died during the study's time horizon. During the terminal phase, 79.3% received at least 1 home care visit, and 58.0% had at least 1 palliative visit. Terminal metastatic colorectal cancer patients received an average of 8 home care visits at Canadian $800 within a 30-day time horizon. Home care costs were highest in the month before death. Male sex, a history of moderate or high utilization of health care services, and hospitalization were associated with lower home care costs.

LIMITATIONS

Administrative data do not reveal the purpose, efficiency, effectiveness/sufficiency, quality, or appropriateness of home care.

CONCLUSION

Patients with advanced colorectal cancer who were approaching death required a moderate level of home care support, resulting in costs of about $5,000 over the 6-month time horizon.

FUNDING

This study was conducted with the support of the Ontario Institute for Cancer Research and Cancer Care Ontario through funding provided by the government of Ontario. Data were provided by Cancer Care Ontario and the Institute for Clinical Evaluative Sciences. The ICES also provided funding for the study from an annual grant by the Ontario Ministry of Health and Long-term Care.

Adjusting for Drug Wastage in Economic Evaluations of New Therapies for Hematologic Malignancies: A Systematic Review

Purpose:

As costs of cancer care rise, there has been a shift to focus on value. Drug wastage affects costs to patients and health care systems without adding value. Historically, cost-effectiveness analyses have used models that assume no drug wastage; however, this may not reflect real-world practices. We sought to identify the frequency of drug wastage modeling in economic evaluations of modern parenteral therapies for hematologic malignancies.

Methods:

We conducted a systematic literature review of economic evaluations of new US Food and Drug Administration–approved parenteral chemotherapies with indications for the treatment of hematologic malignancies. The primary outcome of interest was the proportion of studies that modeled drug wastage in base-case analyses. If wastage was considered in primary analyses, we reported the impact of wastage on incremental cost-effectiveness ratios (ICERs) and drug acquisition costs.

Results:

Wastage was considered in base-case analyses in less than one third of all publications reviewed (12 of 38; 32%). Of these, two studies went on to complete sensitivity analyses and reported significant changes in the calculated ICER as a result. In one study, the ICER increased by 32%, and in the second, accounting for wastage changed a positive ICER to a dominant result.

Conclusion:

Potential costs associated with drug wastage are considered in only one third of modern cost-effectiveness models. The impact of wastage on calculated ICERs and drug acquisition costs is potentially substantial. The modeling of wastage in base-case and sensitivity analyses is recommended for future economic evaluations of new intravenous therapies for hematologic malignancies.

Choosing Wisely in oncology: Screening for a new primary cancer in patients with metastatic disease

295

Background: The Choosing Wisely Canada (CWC) campaign aims to start conversations about unnecessary treatments and procedures in order to improve quality of care. In particular, the CWC campaign in cancer seeks to reduce interventions that are not supported by evidence and contribute to unnecessary rising costs of cancer care. We sought to document the performance of cancer screening for a new primary cancer in patients with existing metastatic cancer (CWC statement #2). Methods: We used population-based administrative health care databases from Ontario, Canada held at the Institute for Clinical Evaluative Sciences (ICES). The cohort included all adult residents of Ontario of eligible screening age (age 50 or older) diagnosed with incident, stage 4 (metastatic) colorectal cancer (CRC), lung, breast, or prostate cancer between January 1, 2007 and December 31, 2012. We examined screening tests for CRC and breast cancer in the first 1 and 3 years after diagnosis of an unrelated cancer. Given the high mortality rate in this population, screening rates were calculated using the cumulative incidence function which takes into account the competing risk of death or the occurrence of the cancer for which the patient was being screened (prior to being screened). Results: Among the 20,992 patients with stage 4 lung, breast, or prostate cancer, CRC screening within 1 year of cancer diagnosis occurred in 2.8%, 6.1%, and 13.0%, respectively. Within 3 years of diagnosis, screening rates were 3.9%, 11.9%, and 26.9%, respectively. Among the 10,034 women with metastatic CRC or lung cancer, breast cancer screening within 1 year of cancer diagnosis occurred in 8.0% and 8.7% of women, respectively. Within 3 years of diagnosis, screening rates were13.1% and 10.2%, respectively. Screening rates were higher in patients age 50-74 than those ≥75 years. Conclusions: Our findings indicate that up to one quarter of patients with metastatic cancer receive subsequent screening tests for other cancers, which are unnecessary as these patients are unlikely to benefit. Further studies are warranted to examine resource implications, potential patient and societal harms, and the future impact of the CWC campaign on this practice.

Publication of quality improvement in medical oncology: A descriptive numerical summary from a scoping review

251

Background: Quality improvement (QI) is becoming a professional expectation and essential to medical oncology practice. A study of medical oncologists found that most QI interventions are not published, suggesting barriers to knowledge dissemination. We aim to describe the authors, settings of QI interventions, and publishing journals of scholarly QI literature. Methods: We conducted a scoping review using Arksey and O'Malley's framework. A search of MEDLINE and EMBASE databases found 48,186 unique English citations from January 2001 to August 2014. Two independent reviewers were responsible for screening the search results and 270 studies were included. Characteristics of first authors, settings of QI interventions, and publishing journals were charted. We used online search engines to find institutional profiles to obtain author and institutional information. A descriptive numerical summary analysis was used to summarize and report the results. Results: The number of QI publications has increased over time, with 60 between 2001 and 2006 and 199 from 2007 to 2013. The majority of first authors are clinicians (65%), of which 59% are physicians, 31% are nurses, and 5% are pharmacists. Furthermore, 27% of first authors are primarily researchers whereas 5% are solely administrators. In addition to professional degrees, having an advanced degree was common amongst clinicians (48% of physicians, 85% of nurses, 44% of pharmacists). Forty-four percent of interventions were conducted in settings affiliated with an academic institution, as opposed to community-based settings. Only 9% of articles were published in a quality of care focused journal. Conclusions: Our scoping review found that most first authors of QI interventions are clinicians, many with an advanced degree in academic settings (rather than community-based settings where most patients receive care). The lack of studies published in quality of care focused journals may result in lost opportunities for knowledge transfer. These findings suggest that more effective knowledge dissemination and increased support for QI studies are needed to further the science of quality and ultimately improve quality of care.

The impact of immigration status on cancer outcomes in Ontario, Canada

285

Background: In the delivery of cancer care, barriers to access could potentially result in inferior outcomes and survival. Although a relationship has been demonstrated between disadvantaged socio-economic status and mortality, the impact of immigration on outcomes is less clear. Methods: Administrative databases were linked to create a cohort of all incident cases of colorectal, lung, prostate, head/neck, breast and hematologic malignancies from Jan 2000 to Dec 2012 in Ontario, Canada. Cases were defined according to immigration status and followed from diagnosis until death (or cancer-specific death). Cox proportional hazards models were constructed to study the impact of immigration status on survival after adjusting for relevant variables. Additional adjusted models studied the relationship of time since immigration on mortality. Results: During the study period, 11,485 cancer cases were diagnosed in recent immigrants (0-10 years in Canada), 17,844 cases in non-recent immigrants (11-25 years), and 416,118 cases in non-immigrants. Following adjustment for relevant predictors by Cox regression, survival was improved for recent immigrants (HR 0.843; 95% CI 0.814-0.873) and non-recent immigrants (HR 0.902; 95% CI 0.876-0.928) compared to non-immigrants. Cancer-specific survival was also better for recent immigrants (HR 0.857; 95% CI 0.823-0.893) and non-recent immigrants (HR 0.907; 95% CI 0.875-0.94) compared to non-immigrants. Amongst immigrants, each year from the original landing in Canada was associated with increased mortality (HR 1.004; 1.000-1.009) and a trend to increased cancer-specific mortality (HR 1.005; 0.999-1.010) that was not statistically significant. Immigrants from all WHO world regions were found to have similar reductions in mortality and cancer-specific mortality. Conclusions: Immigrants to Canada demonstrate a “healthy immigrant” effect, with lower mortality compared to Canadian-born individuals. This benefit appears to diminish over time, as the health of immigrants potentially converges with the Canadian norm. Potential contributors to the benefit include self-selection for immigration, health requirements for entrance, and differences in disease distribution related to ethnicity.

Quality improvement strategies in medical oncology: A qualitative analysis from a scoping review

203

Background: In 2001, the Institute of Medicine (IOM) outlined imperatives to improve quality of care. Quality improvement (QI) has since become essential to cancer care but barriers still exist to the publication of and participation in QI initiatives, including limited recognition for QI and uncertainty with methodologies. We sought to identify strategies used in QI in scholarly medical oncology literature to provide practical guidance for QI. Methods: We conducted a scoping review using Arksey and O’Malley’s framework. A search of EMBASE and MEDLINE databases found 48,186 unique English citations published between January 2001 and August 2014. We utilized an iterative process to refine the inclusion criteria and two reviewers independently reviewed abstracts, resulting in the inclusion of 270 articles. The reviewers then extracted text segments relevant to QI strategies. A qualitative content analysis approach was used to accurately analyze and summarize this process-oriented data. Results: Fifty-four unique QI strategies identified were used alone or in combination to improve structures or processes of care. Five content categories of strategies that targeted structures of care emerged: 1) more methodical approaches (eg, lean thinking, supply-demand analyses), 2) participatory action research and similar strategies, 3) infrastructure to promote health care provider collaboration, 4) application or improvement of information technology (IT), and 5) progression towards a systematic assessment of all patients’ needs. We identified three categories of QI strategies for processes of care: 1) improving patient-clinician relationships or communications, 2) care navigation, and 3) telehealth. Conclusions: Our review identifiedQI strategies in published literature. Strategies were consistent with and expanded on the IOM’s redesign imperatives such as effective use of IT, development of better teams, and care coordination. Identification of strategies provides professionals with tools to engage in QI and may encourage support and recognition for QI. Future studies should examine the impact of different QI strategies on outcomes of care in oncology.

Granulocyte colony-stimulating factor in secondary prophylaxis for advanced-stage Hodgkin lymphoma treated with ABVD chemotherapy: a cost-effectiveness analysis

Granulocyte colony-stimulating factor (G-CSF) is commonly administered to patients with Hodgkin lymphoma (HL) with neutropenia. We constructed a decision-analytic model to compare the cost-effectiveness of secondary prophylaxis with G-CSF to a strategy of 'no G-CSF' in response to severe neutropenia for adults with advanced-stage HL treated with ABVD. A Canadian public health payer's perspective was considered and costs were presented in 2013 Canadian dollars. The quality-adjusted life years (QALYs) attained with the G-CSF and 'no G-CSF' strategies were 1.403 and 1.416, respectively. Costs for the strategies with and without G-CSF were $38,971 and $33,982, respectively. In the base case analysis, the 'no G-CSF' strategy was associated with cost savings and improved QALYs; therefore, 'no G-CSF' was the dominant approach. For patients with severe neutropenia during ABVD chemotherapy for advanced-stage HL, a strategy without G-CSF support is associated with improved quality-adjusted outcomes, cost savings, and is the preferred approach.

Impact of country-specific EQ-5D-3L tariffs on the economic value of systemic therapies used in the treatment of metastatic pancreatic cancer

BACKGROUND

Previous Canadian cost-effectiveness analyses in cancer based on the EQ-5D-3L (EuroQoL, Rotterdam, Netherlands) have commonly used U.K. or U.S. tariffs because the Canadian equivalent only just recently became available. The implications of using non-Canadian tariffs to inform decision-making are unclear. We aimed to reevaluate an earlier cost-effectiveness analysis of therapies for metastatic pancreatic cancer (originally performed using U.S. tariffs) with tariffs from Canada and various other countries to determine the impact of using non-country-specific tariffs.

METHODS

We used tariffs from Canada, the United States, the United Kingdom, Denmark, France, Germany, Japan, the Netherlands, and Spain to derive EQ-5D-3L utilities for the 10 health states in the pancreatic cancer model. Quality-adjusted life years (qalys) and incremental cost-effectiveness ratios (icers) were generated, and probabilistic sensitivity analyses (psas) were performed.

RESULTS

Canadian utilities are generally lower than the corresponding U.S. utilities and higher than those for the United Kingdom. Compared with the Canadian-valued scenarios, U.S. and U.K. estimates were statistically different for 3 and 9 scenarios respectively. Overall, 35% of the non-Canadian utilities (28 of 80) were significantly different, clinically, from the Canadian values. Canadian qalys were 6% lower than those for the United States and 6% higher than those for the United Kingdom. When comparing the qalys of each treatment with those of gemcitabine alone, the average percent change was +6.8% for a U.S. scenario and -7.5% for a U.K. scenario compared with a Canadian scenario. Consequently, Canadian icers were approximately 5.4% greater than those for the United States and 8.6% lower than those for the United Kingdom. Based on the psas and compared with the Canadian threshold value, the minimum willingness-to-pay threshold at which the combination chemotherapy regimen of gemcitabine-capecitabine is the most cost-effective is $5,239 less than in the United States and $11,986 more than in the United Kingdom.

CONCLUSIONS

The use of non-country-specific tariffs leads to significant differences in the derived utilities, icers, and psa results. Past Canadian EQ-5D-3L-based cost-effectiveness analyses and related funding decisions might need to be re-visited using Canadian tariffs.

A population-based study of the epidemiology of pancreatic cancer: a brief report

OBJECTIVE

Administrative data are used to describe the pancreatic cancer (pcc) population. The analysis examines demographic details, incidence, site, survival, and factors influencing mortality in a cohort of individuals diagnosed with pcc.

METHODS

Incident cases of pcc diagnosed in Ontario between 1 January 2004 and 31 December 2011 were extracted from the Ontario Cancer Registry. They were linked by encrypted health card number to several administrative databases to obtain demographic and mortality information. Descriptive, bivariate, and survival analyses were conducted.

RESULTS

During the period of interest, 9221 new cases of pcc (4548 in men, 4673 in women) were diagnosed, for an age-adjusted standardized annual incidence in the range of 8.6-9.5 per 100,000 population. Mean age at diagnosis was 70.3 ± 12.5 years (standard deviation). Five-year survival was 7.2% (12.8% for those <60 years of age and 3.6% for those >80 years of age). Survival varied by sex, older age, rural residence, lower income, site of involvement in the pancreas, and presence of comorbidity.

CONCLUSIONS

The mortality rate in pcc is exceptionally high. With an increasing incidence and a mortality positively associated with age, additional support will be needed for this highly fatal disease as demographics in Ontario continue to trend toward a higher proportion of older individuals.

Impact of renal impairment on outcomes with lenalidomide and dexamethasone treatment in the FIRST trial, a randomized, open-label phase 3 trial in transplant-ineligible patients with multiple myeloma

Renal impairment is associated with poor prognosis in myeloma. This analysis of the pivotal phase 3 FIRST trial examined the impact of renally adapted dosing of lenalidomide and dexamethasone on outcomes of patients with different degrees of renal impairment. Transplant-ineligible patients not requiring dialysis were randomized 1:1:1 to receive continuous lenalidomide and dexamethasone until disease progression (n=535) or for 18 cycles (72 weeks; n=541), or melphalan, prednisone, and thalidomide for 12 cycles (72 weeks; n=547). Follow-up is ongoing. Patients were grouped by baseline creatinine clearance into no (≥ 80 mL/min [n=389]), mild (≥ 50 to < 80 mL/min [n=715]), moderate (≥ 30 to < 50 mL/min [n=372]), and severe impairment (< 30 mL/min [n=147]) subgroups. Continuous lenalidomide and dexamethasone therapy reduced the risk of progression or death in no, mild, and moderate renal impairment subgroups vs. melphalan, prednisone, and thalidomide therapy (HR = 0.67, 0.70, and 0.65, respectively). Overall survival benefits were observed with continuous lenalidomide and dexamethasone treatment vs. melphalan, prednisone, and thalidomide treatment in no or mild renal impairment subgroups. Renal function improved from baseline in 52.6% of lenalidomide and dexamethasone-treated patients. The safety profile of continuous lenalidomide and dexamethasone was consistent across renal subgroups, except for grade 3/4 anemia and rash, which increased with increasing severity of renal impairment. Continuous lenalidomide and dexamethasone treatment, with renally adapted lenalidomide dosing, was effective for most transplant-ineligible patients with myeloma and renal impairment.

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. Cancer 2015;121:3307–3315. © 2015 American Cancer Society.

Cancer patients who receive aggressive end‐of‐life care incur 43% higher costs than those managed nonaggressively; these costs are driven by a heavy dependence on acute institutional care. Palliative consultation may partially offset these costs by tempering the tendency toward aggressive management and offer resultant savings.

Gemcitabine/dexamethasone/cisplatin vs cytarabine/dexamethasone/cisplatin for relapsed or refractory aggressive-histology lymphoma: cost-utility analysis of NCIC CTG LY.12

BACKGROUND

The NCIC CTG LY.12 study showed that gemcitabine, dexamethasone, and cisplatin (GDP) were noninferior to dexamethasone, cytarabine, and cisplatin (DHAP) in patients with relapsed or refractory aggressive histology lymphoma prior to autologous stem cell transplantation. We conducted an economic evaluation from the perspective of the Canadian public healthcare system based on trial data.

METHODS

The primary outcome was an incremental cost utility analysis comparing costs and benefits associated with GDP vs DHAP. Resource utilization data were collected from 519 Canadian patients in the trial. Costs were presented in 2012 Canadian dollars and disaggregated to highlight the major cost drivers of care. Benefit was measured as quality-adjusted life-years (QALYs) based on utilities translated from prospectively collected quality-of-life data. All statistical tests were two-sided.

RESULTS

The mean overall costs of treatment per patient in the GDP and DHAP arms were $19 961 (95% confidence interval (CI) = $17 286 to $24 565) and $34 425 (95% CI = $31 901 to $39 520), respectively, with an incremental difference in direct medical costs of $14 464 per patient in favor of GDP (P < .001). The predominant cost driver for both treatment arms was related to hospitalizations. The mean discounted quality-adjusted overall survival with GDP was 0.161 QALYs and 0.152 QALYs for DHAP (difference = 0.01 QALYs, P = .146). In probabilistic sensitivity analysis, GDP was associated with both cost savings and improved quality-adjusted outcomes compared with DHAP in 92.6% of cost-pair simulations.

CONCLUSIONS

GDP was associated with both lower costs and similar quality-adjusted outcomes compared with DHAP in patients with relapsed or refractory lymphoma. Considering both costs and outcomes, GDP was the dominant therapy.

Health system costs for stage-specific breast cancer: a population-based approach

OBJECTIVE

The objective of the present analysis was to determine the publicly funded health care costs associated with the care of breast cancer (bca) patients by disease stage.

METHODS

Incident cases of female invasive bca (2005-2009) were extracted from the Ontario Cancer Registry and linked to administrative datasets from the publicly funded system. The type and use of health care services were stratified by disease stage over the first 2 years after diagnosis. Mean costs and costs by type of clinical resource used in the care of bca patients were compared with costs for a matched control group. The attributable cost for the 2-year time horizon was determined in 2008 Canadian dollars.

RESULTS

This cohort study involved 39,655 patients with bca and 190,520 control subjects. The average age in those groups was 61.1 and 60.9 years respectively. Most bca patients were classified as either stage i (34.4%) or stage ii (31.8%). Of the bca cohort, 8% died within the first 2 years after diagnosis. The overall mean cost per bca case from a public payer perspective in the first 2 years after diagnosis was $41,686. Over the 2-year time horizon, the mean cost increased by stage: i, $29,938; ii, $46,893; iii, $65,369; and iv, $66,627. The attributable cost of bca was $31,732. Cost drivers were cancer clinic visits, physician billings, and hospitalizations.

CONCLUSIONS

Costs of care increased by stage of bca. Cost drivers were cancer clinic visits, physician billings, and hospitalizations. These data will assist planning and decision-making for the use of limited health care resources.

Quality Improvement: An Assessment of Participation and Attitudes of Medical Oncologists

Canadian medical oncologists face limitations to participating in QI initiatives as a result of lack of time, publication resources, and knowledge about ongoing initiatives. Improving networking opportunities and prioritizing QI at the institutional level can address this need.
