RESUMO
OBJECTIVES: Internationally, there is limited evidence about the role and impact of nurse practitioners (NPs) in complex malignant hematology (CMH). In one Canadian CMH program, NPs have existed for 20 years but not been evaluated. This study aimed to understand stakeholder perceptions of CMH NP role structures, processes, and outcomes and the extent to which the role meets patient and health service needs. METHODS: A qualitative descriptive study was conducted, guided by the PEPPA-Plus framework. Purposive sampling was used to recruit stakeholders who participated in focus groups and interviews. Content analysis was used to analyze the data. RESULTS: Participants included patients (nâ¯=â¯8) and healthcare professionals (nâ¯=â¯27). Themes about structures related to evolution of the CMH Program, model of care, and need for strategic vision. Process themes related to provision of accessible, comprehensive, and holistic care and NP workload. Positive and negative outcomes and lack of outcome measurement were identified. CONCLUSION: Structures related to patient and NP characteristics, organizational change, staffing, and how NP work is organized impacts on NP role implementation and outcomes. Organizational structures can be strengthened to improve the model of care and NP role implementation and workload. Value-added NP contributions related to providing comprehensive care with attention to safety and social determinants of health. Research is needed to evaluate NP role outcomes in CMH. IMPLICATIONS FOR NURSING PRACTICE: The results can inform role design and organization policies and strategies to promote the recruitment, retention, and optimization of NP roles in CMH settings. Priorities for future research are also identified.

OBJECTIVES: The pan-Canadian Oncology Drug Review (pCODR) evaluates new cancer drugs for public funding recommendations. While pCODR's deliberative framework evaluates overall clinical benefit and includes considerations for exceptional circumstances, rarity of indication is not explicitly addressed. Given the high unmet need that typically accompanies these indications, we explored the impact of rarity on oncology HTA recommendations and funding decisions. METHODS: We examined pCODR submissions with final recommendations from 2012 to 2017. Incidence rates were calculated using pCODR recommendation reports and statistics from the Canadian Cancer Society. Indications were classified as rare if the incidence rate was lower than 1/100,000 diagnoses, a definition referenced by the Canadian Agency for Drugs and Technologies in Health. Each pCODR final report was examined for the funding recommendation/justification, level of supporting evidence (presence of a randomized control trial [RCT]), and time to funding (if applicable). RESULTS: Of the ninety-six pCODR reviews examined, 16.6 percent were classified as rare indications per above criteria. While the frequency of positive funding recommendations were similar between rare and nonrare indication (78.6 vs. 75 percent), rare indications were less likely to be presented with evidence from RCT (50 vs. 90 percent). The average time to funding did not differ significantly across provinces. CONCLUSION: Rare indications appear to be associated with weaker clinical evidence. There appears to be no association between rarity, positive funding recommendations, and time to funding. Further work will evaluate factors associated with positive recommendations and the real-world utilization of funded treatments for rare indications.
RESUMO
The International Extranodal Lymphoma Study Group-32 (IELSG32) randomized patients with primary central nervous system lymphoma (PCNSL) for induction treatment with methotrexate-cytarabine, methotrexate-cytarabine-rituximab, or methotrexate-cytarabine-thiotepa-rituximab (MATRix) and reported significantly improved complete remission with the MATRix regimen. This study assessed cost-effectiveness among these three induction strategies for PCNSL. A Markov model was developed based on the IELSG32 trial over a 20 year time horizon from the Canadian health care system perspective. Costs for induction, consolidation, inpatient treatment administration, follow-up, adverse events, relapsed disease, and palliative care were included. Methotrexate-cytarabine-rituximab was subject to extended dominance by the other two strategies. The MATRix regimen compared to methotrexate-cytarabine produced 3.05 quality-adjusted life year (QALY) gains at added costs of $75,513, resulting in an incremental cost-effectiveness ratio of $24,758/QALY gained. The MATRix regimen was the optimal strategy in the majority of simulations (98% probability at willingness-to-pay of $50,000/QALY gained) and results appeared robust across sensitivity analyses.

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.

High dose chemotherapy with autologous stem cell transplantation (ASCT) improves outcomes in patients 65 years of age or less with multiple myeloma. Survival and costs in a cohort of 16 patients who received melphalan and prednisone as part of a clinical trial were compared with those of 36 patients referred to our centre for consideration of ASCT. In the transplant group, survival and costs were extrapolated to match the period of observation in the melphalan and prednisone group. Patient-specific and average costs were calculated from the perspective of the Ontario Ministry of Health. Costs and survival were varied by 50% in the sensitivity analysis. Transplantation improved life expectancy by 19.3 months with a cost difference of 30,517 Canadian dollars. The incremental cost-effectiveness of transplantation compared with melphalan and prednisone was 25,710 Canadian dollars per life-year gained when additional pamidronate and follow-up costs were considered. Discounting costs and survival at 3 and 5% did not result in important differences. The sensitivity analysis resulted in best and worse case scenarios for transplantation compared with melphalan and prednisone of 13,049 dollars and 63,954 dollars per life-year gained respectively. In comparison with melphalan and prednisone, ASCT appears to be cost-effective in patients 65 years old or younger with myeloma.
