Bringing a Systems Approach to Living Donor Kidney Transplantation

BackgroundLiving donor kidney transplantation (LDKT) is the best treatment option for patients with kidney failure. Efforts to increase LDKT have focused on micro-level interventions and the need for systems thinking has been highlighted. We aimed to identify and compare health system-level attributes and processes that are facilitators and barriers to LDKT. MethodsWe conducted a qualitative comparative case study analysis of three Canadian provincial healthcare systems with variable LDKT performance (Quebec:low, Ontario:moderate-high, British Columbia:high). Data collection entailed semi-structured interviews (n=91), document review (n=97) and focus groups (n=5 with 40 participants), analyzed using inductive thematic analysis. ResultsOur findings showed a strong relationship between the degree of centralized coordination between governing organizations and the capacity to deliver LDKT: 1) Macro-level coordination between governing organizations in British Columbia and Ontario increased capacities, while Québec was seen as decentralized with little formal coordination; 2) A higher degree of centralized coordination facilitated more effective resource deployment in the form of human resources and initiatives in British Columbia and Ontario, whereas in Québec resource deployment relied on hospital budgets leading to competition for resources and reduced capacity of initiatives; 3) Informal resource sharing through strong communities of practice and local champions facilitated LDKT in Ontario and British Columbia and was limited in Québec. ConclusionOur findings suggest that interventions that account for full-system function, particularly macro-level coordination between governing organizations can improve LDKT delivery. Findings may be used to guide structured organizational change towards increasing LDKT and mitigating the global burden of kidney failure.

Excess Deaths in Assisted Living and Nursing Homes during the COVID-19 Pandemic in Alberta, Canada

ObjectivesAssisted living (AL) is a significant and growing congregate care option for vulnerable older adults designed to reduce the use of nursing homes (NHs). However, work on excess mortality in congregate care during the COVID-19 pandemic has primarily focused on NHs with only a few US studies examining AL. The objective of this study was to assess excess mortality among AL and NH residents with and without dementia or significant cognitive impairment in Alberta, Canada, during the first 2 years of the COVID-19 pandemic, relative to the 3 years before. DesignPopulation-based, retrospective cohort study. Setting and ParticipantsResidents who lived in an AL or NH facility operated or contracted by the Provincial health care system to provide publicly funded care in Alberta between January 1, 2017, and December 31, 2021. MethodsWe used administrative health care data, including Resident Assessment Instrument – Home Care (RAI-HC, AL) and Minimum Data Set 2.0 (RAI-MDS 2.0, NHs) records, linked with data on residents’ vital statistics, COVID-19 testing, emergency room registrations, and hospital stays. The outcome was excess deaths during COVID-19 (ie, the number of deaths beyond that expected based on pre-pandemic data), estimated, using overdispersed Poisson generalized linear models. ResultsOverall, the risk of excess mortality [adjusted incidence rate ratio (95% confidence interval)] was higher in ALs than in NHs [1.20 (1.14–1.26) vs 1.10 (1.07–1.13)]. Weekly peaks in excess deaths coincided with COVID-19 pandemic waves and were higher among those with diagnosed dementia or significant cognitive impairment in both, AL and NHs. Conclusions and ImplicationsFinding excess mortality within both AL and NH facilities should lead to greater focus on infection prevention and control measures across all forms of congregate housing for vulnerable older adults. The specific needs of residents with dementia in particular will have to be addressed.

Optimization and Local Cost-Effectiveness of Nasopharyngeal Carcinoma Screening Strategies in Southern China: Secondary Analysis of the Guangdong Randomized Trial.

Screening with anti-Epstein-Barr virus (EBV) serology and endoscopy decreased nasopharyngeal carcinoma (NPC) mortality in Guangdong in a randomized trial. We conducted a secondary analysis of this trial using local incidence and cost data to optimize screening programs, hypothesizing that screening could be cost-effective in southern China. Screening costs and life-years after NPC diagnosis were obtained from the Guangdong trial's intent-to-screen population (men and women aged 30-69). Seropositive subjects were rescreened annually for 5 years. Thereafter, we evaluated 12 screening strategies in Guangdong and Guangxi using a validated model. Strategies used combinations of serology, nasopharyngeal swab PCR (NP PCR), endoscopy, and MRI from trial subcohorts. Incidence data and costs were obtained from local cancer registries and the provincial healthcare system. In the intent-to-screen population, screening with serology and endoscopy was cost-effective (¥42,366/life-year, 0.52 GDP per capita). Screening for 5 to 15 years between ages 35 and 59 years met a willingness-to-pay threshold of 1.5 GDP/quality-adjusted life-years in all modeled populations. Despite doubling costs, adding MRI could be cost-effective via improved sensitivity. NP PCR triage reduced endoscopy/MRI referrals by 37%. One-lifetime screen could reduce NPC mortality by approximately 20%. EBV-based serologic screening for NPC is likely to be cost-effective in southern China. Among seropositive subjects, the preferred strategies use endoscopy alone or selective endoscopy triaged by MRI with or without NP PCR. These data may aid the design of screening programs in this region. These findings support population-based screening in southern China by defining the target population, cost-effectiveness, and optimized screening approach.

Framework for policymaking on self-management of health by older adults using technologies

BackgroundDuring the coronavirus disease 2019 (COVID-19) pandemic, the use of information and communication technologies (ICTs) to support care management exponentially increased. Governments around the world adapted existing programs to meet the needs of patients. The reactivity of governments, however, led to changes that were inequitable, undermining groups such as older adults living with chronic diseases and disability. Policies that align with recent developments in ICTs can promote better health outcomes and innovation in care management. A framework for policymaking presents potential for overcoming barriers and gaps that exist in current policies.ObjectiveThe goal of this study was to examine how well a provisional framework for policymaking represented the interactions between various components of government policymaking on older adults’ self-management of chronic disease and disability using ICTs.MethodsThrough an online survey, the study engaged policymakers from various ministries of the government of Ontario in the evaluation and revision of the framework. The data were analyzed using simple statistics and by interpreting written comments.ResultsNine participants from three ministries in the government of Ontario responded to the questionnaire. Overall, participants described the framework as useful and identified areas for improvement and further clarification. A revised version of the framework is presented.ConclusionsThrough the revision exercise, our study confirmed the relevance and usefulness for a policymaking framework on the self-management of disease and disability of older adults’ using ICTs. Further inquiries should examine the application of the framework to jurisdictions other than Ontario considering the dissociated nature of Canadian provincial healthcare systems.

The Elephant in the Nursery: Paediatric Exceptionalism?

Prior to the COVID-19 pandemic (hereafter, ‘the pandemic’), there was already widespread concern about the adequacy of health care resources across Canada. The COVID-19 pandemic exacerbated these concerns exponentially, widening already significant cracks in provincial health care systems. Currently the system is struggling with the exacerbation of wait times for surgeries previously delayed by mandated closures during the pandemic. In Ontario, the backlog of surgeries, and associated backlogs in radiology and other services critical to paediatric care, led to the creation of a consortium of paediatric hospitals committed to advocacy for more funding for paediatrics. Thus far, the provincial and federal governments have agreed to a one-time cash infusion, but the consortium is calling for a permanent increase in funding for paediatrics. A challenge is that the adult sector has also suffered from delays and backlogs. Furthermore, as already noted, older adults have borne the brunt of morbidity and mortality associated with COVID-19. The challenge for the paediatric sector is whether and how to defend the prioritization of children and youth. In this paper, we review four approaches to just allocation – utilitarian ageism, fair innings, the prudential lifespan approach, and prioritarian ageism – and examine their strengths and weaknesses. We conclude by endorsing prioritarian ageism (prioritarianism). Prioritarianism retains the strengths of utilitarian ageism and fair innings while avoiding their weaknesses. Furthermore, because prioritarianism does not treat age as an independent moral criterion, allocation schemes based on this foundation are less susceptible to legal challenge and may be more palatable to the general public.

"The Critical Services Are Out of Reach": Diabetes Management and the Experiences of South Asian Immigrants in Ontario.

Type 2 diabetes is a serious chronic condition affecting millions of people worldwide. South Asians (individuals originating from Pakistan, India, Bangladesh, Sri Lanka, and Nepal) represent a high-risk ethnicity for developing type 2 diabetes (T2D) and experience a high prevalence of the disease, even in migrant populations. The objective of this study was to investigate perceptions and experiences of South Asians living with T2D in Ontario, and their utilization of diabetes related services within the provincial healthcare system. Data were obtained from 20 in-depth interviews with South Asian participants diagnosed with T2D and living in the Greater Toronto Area. Our findings indicate a dissatisfaction with Ontario's coverage for diabetes services; varying uptake of recommended health tests, exams, and monitoring equipment; low utilization of additional resources (diabetes centers); and a need for primary care physicians to better facilitate awareness and utilization of available coverages and resources in the community. This study provides support for the fact that even in Canada's universal healthcare system, disparities exist, particularly for ethnic minorities, and that a universal prescription drug coverage component is a crucial step forward to ensure equitable access to health services utilization for all.

Canadian Landscape Assessment of Colorectal Cancer Screening during the COVID-19 Pandemic.

The COVID-19 pandemic caused disruptions in colorectal cancer (CRC) care by interrupting CRC screening across Canada, posing problems for program participants, patients, and physicians and no clear understanding of how provincial healthcare systems would adapt in the face of another pandemic or shock to the system. A nationwide online survey targeted to members of the National Colorectal Cancer Screening Network (NCCSN) using the SurveyMonkey platform was conducted to gain insight into the impact of the pandemic on CRC screening from March 2020 to March 2022 across all thirteen Canadian jurisdictions. The survey included 25 multiple-choice and free-text questions. Both quantitative and qualitative methods were used to analyze the data using Microsoft Excel and NVivo software. Twenty-one provincial and territorial representatives participated in the survey conducted between 13 May 2022 and 27 October 2022. All jurisdictions (100%) reported decreased screenings, including fecal immunochemical testing (FIT) or Fecal Occult Blood testing (FOBT) procedures, and subsequent diagnostic colonoscopies. The average wait time for colonoscopies due to a positive FIT/FOBT was 76 days. To mitigate the backlog and initiate an effective intervention plan, representatives highlighted some key points, including the importance of prioritizing high-risk patients. Survey results concluded that the COVID-19 pandemic impacted CRC screening across Canada. This landscape assessment can help inform intervention measures and policy-related solutions to create greater resilience for CRC screening in provincial and territorial healthcare systems.

Local Cost-Effectiveness of Nasopharyngeal Carcinoma Screening Strategies in Southern China: Secondary Analysis of the PRO-NPC-001 Cluster-Randomized Trial

Population-based screening for endemic nasopharyngeal carcinoma (NPC) detects most cases at an early stage. In a cluster-randomized trial conducted in Guangdong, a combination of Epstein-Barr Virus (EBV) anti-VCA/EBNA1 IgA serology and endoscopy reduced NPC mortality. We conducted a secondary analysis of this trial in conjunction with local incidence and cost data, hypothesizing that screening would be cost-effective in this region. We estimated population-level NPC mortality reduction, resource utilization, and cost-effectiveness of 12 unique screening strategies in six populations in Guangdong/Guangxi using a previously-validated time-inhomogeneous decision-analytic cohort model. These 12 strategies evaluated combinations of serology, nasopharyngeal swab PCR (NP PCR), endoscopy, and head/neck MRI. Incidence data, screening costs, and healthcare costs were obtained from local cancer registries, laboratories conducting ELISA/PCR, and the Guangdong provincial healthcare system. We evaluated variable screening ages, sexes, intervals, and durations to identify optimal screening approaches from the perspective of the healthcare system in southern China. An incremental cost-effectiveness ratio (ICER) willingness-to-pay threshold of 1.50 times the per-capita GDP was considered cost-effective in southern China. For the base strategy screening 50-year-old men and women using only serology and endoscopy, the average cost per screened subject for a single round of screening over a five-year cycle was ¥175.69. The addition of MRI improved sensitivity (76% vs. 62%) and approximately doubled screening costs. Triage with NP PCR was cost-neutral when used in conjunction with MRI and reduced endoscopy/MRI utilization by 37% with a 3-4% reduction in screening sensitivity. Among 50-year-old men and women, screening was cost-effective in all populations provided that medium-risk subjects were not referred for endoscopy/MRI (ICER/GDP 0.62-0.83). The use of NP PCR without MRI (ICER/GDP 0.83) was dominated by the base strategy (ICER/GDP 0.62) due to higher costs and NPC mortality. After a single five-year screening cycle, screening reduced population NPC mortality by 14% with serology + endoscopy and 21% with serology + endoscopy + MRI. Introduction of MRI with or without NP PCR could be cost-effective in all populations. For MRI-based strategies, the most efficient use of resources was deferral of endoscopy unless MRI was abnormal (ICER/GDP 0.67). Overall, the best-performing strategies balanced NPC mortality, screening costs, and MRI utilization. EBV serology-based screening for endemic NPC is likely to be cost-effective among adult men and women in Guangdong and Guangxi. Referring medium-risk subjects for endoscopy/MRI should be avoided, and NP PCR should be used to triage individuals for MRI rather than endoscopy. These data may aid the design of population-based screening programs in this region.

Cross-jurisdictional pandemic management: providers speaking on the experience of Nunavut Inuit accessing services in Manitoba during the COVID-19 pandemic

ABSTRACT Across Canada, the COVID-19 pandemic placed considerable stress on territorial and provincial healthcare systems. For Nunavut, the need to continue to provide access to critical care to its citizens meant that medical travel to provincial points of care (Edmonton, Winnipeg and Ottawa) had to continue through the pandemic. This complexity created challenges related to the need to keep Nunavut residents safe while accessing care, and to manage the risk of outbreaks in Nunavut resultant from patients returning home. A number of strategies were adopted to mitigate risk, including the expansion of virtual care, self-isolation requirements before returning from Winnipeg, and a level of cross-jurisdictional coordination previously unprecedented. Structural limitations in Nunavut however limited opportunities to expand virtual care, and to allow providers from Manitoba to access the Nunavut’s electronic medical records of patients requiring follow up. Thus, known and long-standing issues exacerbated vulnerabilities within the Nunavut healthcare system. We conclude that addressing cross-jurisdictional issues would be well served by the development of a more formal Nunavut-Manitoba agreement (with similar agreements with Ontario and Alberta), outlining mutual obligations and accountabilities.

The impact on clinical outcomes and healthcare resources from discontinuing colonoscopy surveillance subsequent to low-risk adenoma removal: A simulation study using the OncoSim-Colorectal model.

To estimate the impact on clinical outcomes and healthcare resource use from recommending that patients with 1-2 low-risk adenomas (LRAs) return to routine fecal immunochemical test (FIT) screening instead of surveillance colonoscopy, from a Canadian provincial healthcare system perspective. The OncoSim-Colorectal microsimulation model simulated average-risk individuals eligible for FIT-based colorectal cancer (CRC) screening in Alberta, Canada. We simulated two surveillance strategies that applied to individuals with 1-2 LRAs (<10 mm) removed as part of the average risk CRC screening program: (a) Surveillance colonoscopy (status quo) and (b) return to FIT screening (new strategy); both at 5 years after polypectomy. A 75 ng/mL FIT positivity threshold was used in the base case. The simulations projected average annual CRC outcomes and healthcare resource use from 2023 to 2042. We conducted alternative scenarios and sensitivity analyses on key variables. Returning to FIT screening (versus surveillance colonoscopy) after polypectomy was projected to have minimal impact on long-term CRC incidence and deaths (not statistically significant). There was a projected decrease of one (4%) major bleeding event and seven (5%) perforation events per year. There was a projected increase of 4800 (1.5%) FIT screens, decrease of 3900 (5.1%) colonoscopies, and a decrease of $3.4 million (1.2%) in total healthcare costs per year, on average. The annual colonoscopies averted and healthcare cost savings increased over time. Results were similar in the alternative scenarios and sensitivity analyses. Returning to FIT screening would have similar clinical outcomes as surveillance colonoscopy but could reduce colonoscopy demand and healthcare costs.

"Collapsing into Darkness": An Exploratory Qualitative Thematic Analysis of the Experience of Workplace Reintegration among Nurses with Operational Stress Injuries.

Nurses are engaged in an unpredictable and dynamic work environment where they are exposed to events that may cause or contribute to physical and/or psychological injuries. Operational stress injury (OSI) may lead to an extended time away from work or nurses leaving the profession altogether. A deliberate focus on the workplace reintegration phase of the mental health recovery process may lead to the increased retention of nurses in their profession. Prior to the creation and implementation of potential solutions to address workplace reintegration, it is imperative to explore the experiences and perceptions of nurses affected by OSI. This qualitative study aims to investigate the experiences and perceptions of nurses (N = 7) employed within a Canadian provincial healthcare system who have attempted workplace reintegration after being off of work with an OSI. Nurses were recruited via social media, unit emails, and word of mouth. Data were collected through recorded semi-structured interviews conducted over videoconferencing. Once transcribed, the data were thematically analyzed using an inductive approach. The resulting themes included (1) heroes to zeros, (2) changing the status quo, (3) connection is key, and (4) post-traumatic growth: advocacy and altruism. Study participants indicated both that nursing culture and a cumulation of events contributed to a need for a leave of absence from work and that a formalized process was desired by nurses to assist in returning to work. The development, implementation, and exploration of innovative policies, procedures, and initiatives to bridge the gap from clinical interventions to workplace reintegration are needed for nurses experiencing OSI. Further research is also needed regarding mental health impacts and appropriate resources to support nurses in their workplace reintegration process after experiencing psychological and/or physical injury.

Facilitators and Barriers to Nurses Screening for Frailty in Acute Care in a Provincial Health-Care System: a Survey Study Guided by the Theoretical Domains Framework.

Older adults living with frailty represent the largest population of hospitalized patients in Canada, but they do not always receive the quality of care needed. Nurses are well-positioned to screen for frailty, but current frailty screening practices are poorly understood. A cross-sectional survey study was conducted over a six-week period with nurses from Alberta, Canada working in acute care with older adults. Demographics were descriptively reported. Frailty screening methods were quantified on 5-point frequency scales, reported descriptively and compared by practice area using linear regression. The top-five mean scores from a 43-item, 6-point Likert-type questionnaire based on the Theoretical Domains Framework were compared by practice area. Frailty screening by clinical impression was "usually" used (median = 4, IQR = 4-5), while tools were "rarely" used (median = 2, IQR = 1-3). Medical and/or surgical nursing had higher general frailty screening tool use (β = 0.81, r = .31, p < .001), but no significant (p > .05) differences for using clinical impression, or preference of screening method. The top facilitator was the disbelief that frailty screening negatively impacts relationships with older adults. The top barrier was belief that conducting frailty screening was routine. Nursing practice area influenced frailty screening beliefs. There is an opportunity to implement frailty screening tools into the nursing practice of Alberta' nurses working in acute care. Frailty screening tools that become routine have greater likelihood for utilization. Nursing practice areas may have unique situations that require tailored approached to tool implementation.

Perceptions of Service Climate in a Canadian healthcare system.

Perceptions of Service Climate in healthcare organizations are important because of their linkages to patient and organizational outcomes. This article presents findings from survey data collected from frontline nurses (n = 275) in Canada who were working in a provincial healthcare system that had recently undergone significant structural changes. The findings indicate that frontline nurses held a neutral view of the Service Climate overall but a strong and negative perception of Managerial Service Practices. The results suggest that some service practices existed in nurses' working environments; however, improvements could be made in the areas of recognizing and rewarding those who consistently provide high levels of quality service. This has implications for not only continuous quality improvement but also for the patient and staff experience in healthcare.

The Patient-Provider Gap: A Cross-sectional Survey to Understand Barriers and Motivating Factors for Home Blood Pressure Monitoring in a CKD Cohort

Blood pressure (BP) management can decrease morbidity and mortality in chronic kidney disease (CKD) patients. Evidence-based hypertension guidelines endorse home BP monitoring (HBPM), and the growing use of virtual health has highlighted the need for HBPM. A comprehensive understanding of HBPM adoption in our province is lacking. To identify the baseline practices, perspectives, barriers, and enablers in both providers and patients in our kidney care clinics regarding HBPM. Ultimately, this will inform the development of a provincial intervention that empowers providers to both increase patient understanding and equip them for accurate and reliable home BP measurement. Cross-sectional, descriptive study using online survey methodology. Kidney care clinic network in the province of British Columbia, Canada. Kidney care clinic staff and patients who perform HBPM. Data were collected using semi-structured online surveys, one for staff and one for patients and/or caregivers. These surveys were developed by an interdisciplinary working group that included patient partners and addressed some key components of the implementation of an HBPM program (including perceived barriers to uptake, education, and adoption of best practices). In all, 46 patients and 43 staff responded to the survey from 16 kidney care clinics. Of the patients 53% were women, and the most common age range was 60 to 69 years (25%); 93% of the staff respondents were women and 63% were nurses. We identified numerous areas of discordance between providers and patients and the need for improvement from the perspective of implementing best practices from hypertension guidelines, both in staff teaching and patient usage of HBPM. Blood pressure targets were not known to 18% of patients and 39% of patients had received a BP target from their kidney care clinic team; 89% of patients had not had their upper arm circumference measured for cuff size. Furthermore, 54% of patients knew what to do when their BP is off-target. All recognized the benefits of HBPM, providers were more likely to perceive anxiety as a barrier relative to patients, and patients were more likely to report expense as a barrier than providers. This study includes only a single provincial health care system limiting generalizability to other jurisdictions and sampled a small subset of patients and providers. The systematic evaluation of education, understanding, implementation of best practices, and barriers and motivating factors for HBPM from both patient and clinician perspectives is an important step in designing strategies to improve the use of HBPM. Given differences in staff and patient perspectives, targeted interventions based on these responses may lead to improved use of HBPM, and ultimately enhance hypertension self-management and BP control in our CKD patients.

Association between influenza vaccination and risk of stroke in Alberta, Canada: a population-based study

Respiratory infection can be an immediate precursor to stroke and myocardial infarction. Influenza vaccination is associated with reduced risk of myocardial infarction and hospitalisation for cardiac disease, and influenza vaccination is strongly recommended for patients with heart disease. Evidence on whether the same protective association exists for stroke, and whether this potential effect is consistent across age and risk groups, is conflicting. We aimed to assess the risk of stroke after influenza vaccination in adults. We obtained administrative data from the Alberta Health Care Insurance Plan (which covers all residents of Alberta, Canada) beginning on Sept 30, 2009, or May 15 of the year in which residents were recorded as being 18 years of age. Individuals were censored at the earliest of three events: death, recorded outmigration, or Dec 31, 2018. The outcome of interest was any stroke event, comprising acute ischaemic stroke, intracerebral haemorrhage, subarachnoid haemorrhage, and transient ischaemic attack. We used Andersen-Gill Cox models to analyse the hazard of any stroke event for individuals with recent (&lt;182 days) influenza vaccination compared with those without recent influenza vaccination, with adjustment for age, sex, anticoagulant use, atrial fibrillation, chronic obstructive pulmonary disease, diabetes, hypertension, income quintile, and rural or urban home location. Two-way interaction terms between each individual covariate and vaccination status were used to assess for effect modification by risk factor. The association between vaccination and risk of each type of stroke was also modelled, adjusting for baseline covariates. The study sample consisted of 4 141 209 adults (29 687 899 person-years of observation time) registered under the provincial health-care system between Sept 30, 2009, and Dec 31, 2018. 1 769 565 (42·73%) individuals received at least one vaccination during the study period, and 38 126 stroke events were recorded. Adjusted for demographics and comorbidities, recent influenza vaccination significantly reduced the hazard of stroke (hazard ratio 0·775 [95% CI 0·757-0·793]). This association persisted across all stroke types. We found effect modification by each covariate examined except for home location; however, vaccination was associated with a reduced risk of stroke overall across all ages and risk profiles with the exception of individuals without hypertension. The risk of stroke is reduced among people who have recently been vaccinated against influenza compared with those who have not. This association extended to the entire adult population and was not limited to individuals with a baseline high risk of stroke. Further studies in a variety of settings are needed to evaluate whether influenza vaccination could be used as a public health strategy to prevent stroke. None.

Molecular testing for adolescent and young adult central nervous system tumors: A Canadian guideline.

The 2021 World Health Organization (WHO) classification of CNS tumors incorporates molecular signatures with histology and has highlighted differences across pediatric vs adult-type CNS tumors. However, adolescent and young adults (AYA; aged 15–39), can suffer from tumors across this spectrum and is a recognized orphan population that requires multidisciplinary, specialized care, and often through a transition phase. To advocate for a uniform testing strategy in AYAs, pediatric and adult specialists from neuro-oncology, radiation oncology, neuropathology, and neurosurgery helped develop this review and testing framework through the Canadian AYA Neuro-Oncology Consortium. We propose a comprehensive approach to molecular testing in this unique population, based on the recent tumor classification and within the clinical framework of the provincial health care systems in Canada.Contributions to the fieldWhile there are guidelines for testing in adult and pediatric CNS tumor populations, there is no consensus testing for AYA patients whose care occur in both pediatric and adult hospitals. Our review of the literature and guideline adopts a resource-effective and clinically-oriented approach to improve diagnosis and prognostication of brain tumors in the AYA population, as part of a nation-wide initiative to improve care for AYA patients.

P-617 Cost-effectiveness analysis of In Vitro Fertilization (IVF) antagonist protocols utilizing highly purified human menopausal gonadotropin (HP-hMG) and three different recombinant FSH (rFSH) preparations

Abstract Study question Is there a mixed ovarian stimulation antagonist protocol for IVF that obtains more good quality blastocysts with less cost? Summary answer Mixed protocol of HP-hMG and follitropin delta obtains a significantly more good quality blastocysts with significantly lower cost per embryo obtained. What is known already FSH and LH are used for controlled ovarian stimulation (COS) to increase the number of oocytes produced in IVF. Determination of a stimulation protocol and FSH dosage is generally established by the physician based on the patient’s age, body weight and ovarian reserve profile. Mixed protocols (concomitant HP-hMG and rFSH) for ovarian stimulation have been used to obtain better quality oocytes and embryos and thus, higher pregnancy rates compared to the use of rFSH alone. However, to date no data exist comparing cost-effectiveness of mixed protocols using different rFSH preparations. Study design, size, duration This is a cost-effectiveness analysis of the retrospective cohort study encompassing COS for IVF with 3 different mixed protocols performed between January 2018 and September 2019 in 2 fertility clinics. The 267 subjects evaluated were between 18 and 42 years of age and were divided into 3 groups of 89 subjects each according to the rFSH used: group A follitropin alfa; group B follitropin beta and group D follitropin delta. Participants/materials, setting, methods HP-hMG was used in all three groups while different rFSH was prescribed. All three groups used an antagonist protocol. IVF or intra-cytoplasmatic sperm injection (ICSI) was used as clinically indicated. Resulting embryos were cultured until day 5 or 6. The dose of gonadotropins used, the number of mature oocytes (MII), the number of utilizable blastocysts and the FSH/blastocyst ratio were evaluated. For cost-effectiveness analysis we used prices accepted by the provincial healthcare system in Quebec. Main results and the role of chance The mean age of subjects was 34.62 years (± 3.74) and weight 71.65 kg (± 14.61). No significant differences were observed in age or weight among groups. Since follitropin delta is administered in micrograms, the comparison between rFSH preparations was performed using dose equivalence between (10 µg follitropin delta) and (150 IU follitropin alpha and beta). Statistically significant differences were observed among groups in mean total dose of FSH (IU) (A = 4269 IU vs. B = 3947 IU vs. D = 3713 IU, p = 0.01), and number of days of stimulation (A = 11.6 vs. B = 10.6 vs. D = 11.4, p &amp;lt; 0.01). Group D used less gonadotropins despite a longer stimulation. No statistically significant differences were observed in the number of MII oocytes. However, the number of good quality utilizable blastocysts was significantly higher in group D (4.8) than in group A (3.9) or B (3.6). The FSH/blastocyst ratio was significantly lower in group D (370) than in the other groups (A = 541, B = 653). The total price per cycle was similar (A= $4,028 vs. B= $3,649 D= $3,740), however the price per embryo obtained was significantly lower in group D ($779) than in the other groups (A= $1,033, B= $1,014). Limitations, reasons for caution The limitation of this cost-effectiveness analysis is the retrospective nature of the study. Wider implications of the findings Our analysis demonstrates that the price per cycle was similar between the groups, however the price per embryo obtained was significantly lower in group D compared to the other groups. This gives follitropin delta an advantage in terms of cost-effectiveness. Trial registration number NA

Expected Cost Savings From Low-Dose Computed Tomography Scan Screening for Lung Cancer in Alberta, Canada

IntroductionThe expensive modern therapeutic regimens for advanced lung cancer (LC) stages have been recently approved. We evaluated whether low-dose computed tomography (LDCT) LC screening of high-risk Albertans is cost saving. MethodsWe used a decision analytical modeling technique with a health system perspective and a time horizon of 3 years to compare benefits associated with reduced health service utilization (HSU) from earlier diagnosis to the costs of screening. Using patient-level data, HSU costs by stage of disease were estimated for patients with LC, including inpatient, outpatient, and physician services, and costs for prescription drugs and cancer treatments. ResultsOf 101,000 people aged 55 to 74 years eligible for screening, an estimated 88,476 scans would be performed in Alberta in 3 years. Given LDCT sensitivity and specificity of 90.5% and 93.1%, respectively, we estimated that a stage shift toward earlier diagnosis would be expected whereby 43% more patients would be identified at stage 1 or 2 as compared with without screening. The estimated cost of screening is $35.6 million (M), whereas the stage shift associated with screening would avoid $42M in HSU costs. The net cost avoidance associated with screening is therefore $6.65M. The probability for the screening to be cost saving is estimated at 72%. ConclusionsThis study has revealed that LDCT LC screening is likely to be cost saving in Alberta. Adoption of this program into the provincial health care system is worth considering provided constraints in the system related to surgical capacity and CT wait times could be addressed.

Appropriateness of Outpatient Antibiotic Use in Seniors across Two Canadian Provinces.

Antimicrobials are among the most prescribed medications in Canada, with over 90% of antibiotics prescribed in outpatient settings. Seniors prescribed antimicrobials are particularly vulnerable to adverse drug events and antimicrobial resistance. The extent of inappropriate antibiotic prescribing in outpatient Canadian medical practice, and the potential long-term trends in this practice, are unknown. This study is the first in Canada to examine prescribing quality across two large-scale provincial healthcare systems to compare both quantity and quality of outpatient antibiotic use in seniors. Population-based analyses using administrative health databases were conducted in British Columbia (BC) and Ontario (ON), and all outpatient, oral antimicrobials dispensed to seniors (≥65 years) from 1 January 2000 to 31 December 2018 were identified. Antimicrobials were linked to an indication using a 3-tiered hierarchy. Tier 1 indications, which always require antibiotics, were given priority, followed by Tier 2 indications that sometimes require antibiotics, then Tier 3, which never require antibiotics. Prescription rates were calculated per 1000 population, and trends were examined overall, by drug class, and by patient demographics. Prescribing remained steady in both provinces, with 11,166,401 prescriptions dispensed overall in BC, and 27,656,014 overall in ON. BC prescribed at slightly elevated rates (range: 790 to 930 per 1000 residents), in comparison to ON (range: 745 to 785 per 1000 residents), throughout the study period. For both provinces, a Tier 3 diagnosis was the most common reason for antibiotic use, accounting for 50% of all indication-associated antibiotic prescribing. Although Tier 3 indications remained the most prescribed-for diagnoses throughout the study period, a declining trend over time is encouraging, with much room for improvement remaining. Elevated prescribing to seniors continues across Canadian outpatient settings, and prescribing quality is of high concern, with 50% of all antimicrobials prescribed inappropriately for common infections that do not require antimicrobials.
