Abortion Safety and Use with Normally Prescribed Mifepristone in Canada.

BACKGROUND: In the United States, mifepristone is available for medical abortion (for use with misoprostol) only with Risk Evaluation and Mitigation Strategy (REMS) restrictions, despite an absence of evidence to support such restrictions. Mifepristone has been available in Canada with a normal prescription since November 2017. METHODS: Using population-based administrative data from Ontario, Canada, we examined abortion use, safety, and effectiveness using an interrupted time-series analysis comparing trends in incidence before mifepristone was available (January 2012 through December 2016) with trends after its availability without restrictions (November 7, 2017, through March 15, 2020). RESULTS: A total of 195,183 abortions were performed before mifepristone was available and 84,032 after its availability without restrictions. After the availability of mifepristone with a normal prescription, the abortion rate continued to decline, although more slowly than was expected on the basis of trends before mifepristone had been available (adjusted risk difference in time-series analysis, 1.2 per 1000 female residents between 15 and 49 years of age; 95% confidence interval [CI], 1.1 to 1.4), whereas the percentage of abortions provided as medical procedures increased from 2.2% to 31.4% (adjusted risk difference, 28.8 percentage points; 95% CI, 28.0 to 29.7). There were no material changes between the period before mifepristone was available and the nonrestricted period in the incidence of severe adverse events (0.03% vs. 0.04%; adjusted risk difference, 0.01 percentage points; 95% CI, -0.06 to 0.03), complications (0.74% vs. 0.69%; adjusted risk difference, 0.06 percentage points; 95% CI, -0.07 to 0.18), or ectopic pregnancy detected after abortion (0.15% vs. 0.22%; adjusted risk difference, -0.03 percentage points; 95% CI, -0.19 to 0.09). There was a small increase in ongoing intrauterine pregnancy continuing to delivery (adjusted risk difference, 0.08 percentage points; 95% CI, 0.04 to 0.10). CONCLUSIONS: After mifepristone became available as a normal prescription, the abortion rate remained relatively stable, the proportion of abortions provided by medication increased rapidly, and adverse events and complications remained stable, as compared with the period when mifepristone was unavailable.

A Prognostic Survival Model Incorporating Patient-Reported Outcomes for Transplant-Ineligible Patients With Multiple Myeloma.

Developing prognostic tools specifically for patients themselves represents an important step in empowering patients to engage in shared decision-making. Incorporating patient-reported outcomes may improve the accuracy of these prognostic tools. We conducted a retrospective population-based study of transplant-ineligible (TIE) patients with multiple myeloma (MM) diagnosed between January 2007 and December 2018. A multivariable Cox regression model was developed to predict the risk of death within 1-year period from the index date. We identified 2356 patients with TIE MM. The following factors were associated with an increased risk of death within 1 year: age > 80 (HR 1.11), history of heart failure (HR 1.52), "CRAB" at diagnosis (HR 1.61), distance to cancer center (HR 1.25), prior radiation (HR 1.48), no proteosome inhibitor/immunomodulatory therapy usage (HR 1.36), recent emergency department (HR 1.55) or hospitalization (HR 2.13), poor performance status (ECOG 3-4 HR 1.76), and increasing number of severe symptoms (HR 1.56). Model discrimination was high with C-statistic of 0.74, and calibration was very good. To our knowledge, this represents one of the first prognostic models developed in MM incorporating patient-reported outcomes. This survival prognostic tool may improve communication regarding prognosis and shared decision-making among older adults with MM and their health care providers.

Development and validation of thromboembolism diagnostic algorithms in children with cancer from real-world data.

OBJECTIVE: To evaluate the accuracy of diagnostic algorithms developed using the International Classification of Diseases (ICD-9-CM and ICD-10-CA) diagnostic codes and physician billing codes for thromboembolism (TE) from health administrative data compared to chart review diagnoses of TE in children with cancer. METHODS: Using data linkage between the Pediatric Oncology Group of Ontario Network Information System (Ontario pediatric cancer registry) and various administrative data housed at ICES, eight algorithms were developed including a single reference to one of the billing codes, multiple references with varying time intervals, and combinations of various billing codes during primary cancer therapy for the whole cohort and, for early (<04/2002) and later (≥04/2002, solely ICD-10 codes) periods. Reference standard was chart review data from prior studies (from 1990 to 2016) among children (≤19 years) with cancer and radiologically confirmed TE. RESULTS: Records of 2056 patients diagnosed with cancer at two participating sites during study period were reviewed; 112 had radiologically confirmed TE. The algorithm with addition of anticoagulation utilization codes was the best performing algorithm (sensitivity = 0.76;specificity = 0.85). With use of ICD-10 only codes, sensitivity of the same algorithm improved to 0.84 with specificity of 0.80. CONCLUSION: This study provides a valid approach for ascertaining pediatric TE using real-world data. IMPACT: Research in pediatric thrombosis, especially cancer-related thrombosis, is limited mainly due to small-sized studies. Real-world data provide ready access to large and diverse populations. However, there are no validated algorithms for identifying thrombosis in real-world data for children. An algorithm based on combination of thrombosis and anticoagulation utilization codes had 76% sensitivity and 85% specificity to identify diagnosis of thrombosis in children in administrative data. This study provides a valid approach for ascertaining pediatric thrombosis using real-world data and offers a good avenue to advance pediatric thrombosis research.

Cancer-specific mortality in multiple myeloma: a population-based retrospective cohort study.

Survival has improved in patients diagnosed with multiple myeloma (MM) over the last two decades; however, there remains a paucity of data on the causes of death in MM patients and whether causes of death change during the disease trajectory. We conducted a retrospective population-based study to evaluate the rates of MM-specific versus non-MM cause of death and to identify factors associated with cause-specific death in MM patients, stratified into autologous stem cell transplant (ASCT) and non-ASCT cohorts. A total of 6,677 patients were included, 2,576 in the ASCT group and 4,010 in the non-ASCT group. Eight hundred and seventy-three (34%) ASCT patients and 2,787 (68%) non-ASCT patients died during the follow-up period. MM was the most frequent causes of death, causing 74% of deaths in the ASCT group and 67% in the non-ASCT group. Other cancers were the second leading causes of death, followed by cardiac and infectious diseases. Multivariable analysis demonstrated that a more recent year of diagnosis and novel agent use within 1 year of diagnosis were associated with a decreased risk of MM-specific death, whereas a history of previous non-MM cancer, older age, and the presence of CRAB criteria at diagnosis increased the risk of non-MM death. Our data suggests that despite improvement in MM outcomes in recent years, MM remains the greatest threat to overall survival for patients. Further advances in the development of effective MM therapeutic agents in both ASCT and non-ASCT populations and patient access to them is needed to improve outcomes.

Palliative care utilization across health sectors for patients with gynecologic malignancies in Ontario, Canada from 2006 to 2018.

OBJECTIVE: Early palliative care (PC) is associated with improved patient quality of life, less aggressive end-of-life care, and prolonged survival. We evaluated patterns of PC delivery in gynecologic oncology. METHODS: We conducted a population-based, retrospective cohort study of gynecologic cancer decedents in Ontario from 2006 to 2018 using linked administrative health care data. RESULTS: The cohort included 16,237 decedents; 51.1% died of ovarian cancer, 30.3% uterine cancer, 12.1% cervical cancer, and 6.5% vulvar/vaginal cancers. Palliative care was most often delivered in the hospital inpatient setting in 81%, and 53% received specialist PC. PC was first received during hospital admission in 53%, and by outpatient physician care in only 23%. Palliative care was initiated a median 193 days prior to death, with the lowest two quintiles initiating care ≤70 days before death. The average user of PC resources (third quintile) received 68 days of PC. While cumulative use of community PC gradually increased over the final year of life, institutional palliative care use exponentially rose from 12 weeks until death. On multivariable analyses, predictors of initiating palliative care during a hospital admission included age ≥70 years at death, ≤3 month cancer survival, having cervical or uterine cancer, not having a primary care provider, or being in the lowest 3 income quintiles. CONCLUSION: Most palliative care is initiated and delivered during hospital admission, and is initiated late in a significant proportion. Strategies to increase access to anticipatory and integrated palliative care may improve the quality of the disease course and the end of life.

Cardiovascular outcomes in children with Kawasaki disease: a population-based cohort study.

BACKGROUND: The risk of cardiovascular events after Kawasaki disease (KD) remains uncertain. Our objective was to determine the risk of cardiovascular events and mortality after KD. METHODS: Population-based retrospective cohort study using Ontario health administrative databases (0-18 years; 1995-2018). EXPOSURE: pediatric KD hospitalizations. Each case was matched to 100 non-exposed controls. PRIMARY OUTCOME: major adverse cardiac events (MACE; cardiovascular death, myocardial infarction, or stroke composite). SECONDARY OUTCOMES: composite cardiovascular events and mortality. We determined incidence rates and adjusted hazard ratios (aHR) using multivariable Cox models. RESULTS: Among 4597 KD survivors, 79 (1.7%) experienced MACE, 632 (13.8%) composite cardiovascular events, and 9 (0.2%) died during 11-year median follow-up. The most frequent cardiovascular events among KD survivors were ischemic heart disease (4.6 events/1000 person-years) and arrhythmias (4.5/1000 person-years). KD survivors were at increased risk of MACE between 0-1 and 5-10 years, and composite cardiovascular events at all time periods post-discharge. KD survivors had a lower mortality risk throughout follow-up (aHR 0.36, 95% CI 0.19-0.70). CONCLUSION: KD survivors are at increased risk of post-discharge cardiovascular events but have a lower risk of death, which justifies enhanced cardiovascular disease surveillance in these patients. IMPACT: Among 4597 Kawasaki disease (KD) survivors, 79 (1.7%) experienced major adverse cardiac events (MACE) and 632 (13.8%) had composite cardiovascular events during 11-year median follow-up. KD survivors had significantly higher risks of post-discharge MACE and cardiovascular events versus non-exposed children. Only nine KD survivors (0.2%) died during follow-up, and the risk of mortality was significantly lower among KD survivors versus non-exposed children. Childhood KD survivors should receive preventative counseling and cardiovascular surveillance, aiming to mitigate adult cardiovascular disease.

A diagnostic subgroup comparison of health care utilization patterns in individuals with eating disorders diagnosed in childhood and/or adolescence.

OBJECTIVE: This study examined a 2-year period after diagnosis of an eating disorder to compare health care utilization in diagnostic subgroups including: anorexia nervosa (AN), bulimia nervosa (BN), binge-eating disorder (BED), avoidant/restrictive food intake disorder (ARFID), and other specified eating disorders (Other). METHOD: We conducted a retrospective study of children diagnosed with AN (n = 674), BN (n = 230), BED (n = 59), ARFID (n = 171), and Other (n = 315). We used a general population cohort for comparison, matched 5:1 to the diagnostic subgroups on sex and birth date. We then conducted a separate analysis using the ARFID subgroup as a reference group compared to the other subgroups. Outcomes were determined using data linkage with health administrative databases and included hospitalizations, emergency department, general practitioner, psychiatry, and pediatrician visits. Odds ratios (dichotomous outcomes) and rate ratios (continuous outcome) were calculated. RESULTS: Mental health care utilization was higher for all subgroups compared to the general population. When the subgroups were compared to the ARFID subgroup, those with ARFID appeared to have similar health care utilization to the other subgroups, except when compared to those with AN. The AN subgroup had higher odds of a mental health related hospitalization (OR 1.62, 95% CI 1.04-2.5) higher rates of mental health related pediatrician visits (RR 1.76, 95% CI 1.26-2.46) and psychiatry visits (RR 1.69, 95% CI 1.07-2.68). CONCLUSIONS: Those with ARFID have similar utilization as other subtypes of eating disorders, except when compared to those with AN who have higher health care utilization. PUBLIC SIGNIFICANCE: Our study found that the health service needs of young people with all types of eating disorders are substantially higher than the general population, and it appears that Avoidant/Restrictive Food Intake Disorder (ARFID) has similar health care utilization to other eating disorders.

Cardiovascular Outcomes During Index Hospitalization in Children with Kawasaki Disease in Ontario, Canada.

Kawasaki disease (KD) is a common childhood vasculitis associated with coronary artery aneurysms (CAA). However, there is limited published data on other cardiovascular events diagnosed during acute KD hospitalizations. Our objectives were to determine the incidence of cardiovascular events during acute KD hospitalizations, stratified by age at admission, CAA status, and pediatric intensive care unit (PICU) admission status. We identified all children (0-18 year) hospitalized with a new KD diagnosis in Ontario, between 1995 and 2018, through validated algorithms using population health administrative databases. We excluded children previously diagnosed with KD and non-Ontario residents. We evaluated for cardiovascular events that occurred during the acute KD hospitalizations, defined by administrative coding. Among 4597 children hospitalized with KD, 3307 (71.9%) were aged 0-4 years, median length of stay was 3 days (IQR 2-4), 113 children (2.5%) had PICU admissions, and 119 (2.6%) were diagnosed with CAA. During acute hospitalization, 75 children were diagnosed with myocarditis or pericarditis (1.6%), 47 with arrhythmias (1.0%), 25 with heart failure (0.5%), and ≤ 5 with acute MI (≤ 0.1%). Seven children underwent cardiovascular procedures (0.2%). Older children (10-18 years), children with CAA, and children admitted to the PICU were more likely to experience cardiovascular events, compared with children aged 0-4 years, without CAA or non-PICU admissions, respectively. The frequency of non-CAA cardiovascular events during acute KD hospitalizations did not change significantly between 1995 and 2018. During acute KD hospitalizations, older children, children with CAA, and PICU admissions are at higher risk of cardiovascular complications, justifying closer monitoring of these high-risk individuals.

Was Virtual Care as Safe as In-Person Care? Analyzing Patient Outcomes at Seven and Thirty Days in Ontario during the COVID-19 Pandemic.

In 2020, almost overnight, the paradigm for healthcare interactions changed in Ontario. To limit person-to-person transmission of COVID-19, the norm of in-person interactions shifted to virtual care. While this shift was part of broader public health measures and an acknowledgment of patient and societal concerns, it also represented a change in care modalities that had the potential to affect the quality of care provided, as well as short- and long-term patient outcomes. While public policy decisions were being made to moderate the use of virtual care at the end of the declared pandemic, a thorough analysis of short-term patient outcomes was needed to quantify the impact of virtual care on the population of Ontario.

Quality of end-of-life care in multiple myeloma: A 13-year analysis of a population-based cohort in Ontario, Canada.

Optimizing end-of-life (EOL) care for multiple myeloma (MM) represents an unmet need. An administrative cohort in Ontario, Canada was analysed between 2006 and 2018. Aggressive care was defined as two or more emergency-department visits in the last 30 days before death, or at least two new hospitalizations within 30 days of death, or an intensive care unit (ICU) admission within the last 30 days of life. Supportive care was defined as a physician house-call in the last two weeks before death, or a palliative nursing or personal support visit at home in the last 30 days before death. Among 5095 patients, 23.2% of patients received chemotherapy at EOL and 55.6% of patients died as inpatient. A minority received aggressive care at EOL [28.3%: autologous stem cell transplant (ASCT), 20.4%: non-ASCT], and a majority received supportive care at EOL (65.4%: ASCT, 61.5%: non-ASCT). Supportive care was less likely to be received by those aged over 80 years and in lower-income neighbourhoods. Supportive care at EOL increased from 56.0% in 2006 to 70.3% in 2018. Despite improvements, many patients with MM experience aggressive care at EOL. Even in a publicly funded health care system, disparities based on age, income and community size are present.

Trends in quality indicators of end-of-life care for women with gynecologic malignancies in Ontario, Canada.

OBJECTIVE: A large body of research has validated several quality indicators of end-of-life (EOL) cancer care, but few have examined these in gynecologic cancer at a population-level. We examined patterns of EOL care quality in patients with gynecologic cancers across 13 years in Ontario, Canada. METHODS: We conducted a population-based, retrospective cohort study of gynecologic cancer decedents in Ontario from 2006 to 2018 using linked administrative health care databases. Proportions of quality indices were calculated, including: emergency department (ED) use, hospital or intensive care unit (ICU) admission, chemotherapy ≤14 days of death, cancer-related surgery, tube or intravenous feeds, palliative home visits, and hospital death. We used multivariable logistic regression to examine factors associated with receipt of aggressive and supportive care. RESULTS: There were 16,237 included decedents over the study period; hospital death rates decreased from 47% to 37%, supportive care use rose from 65% to 74%, and aggressive care remained stable (16%). Within 30 days of death, 50% were hospitalized, 5% admitted to ICU, and 67% accessed palliative homecare. Within 14 days of death, 31% visited the ED and 4% received chemotherapy. Patients with vulvovaginal cancers received the lowest rates of aggressive and supportive care. Using multivariable analyses, factors associated with increased aggressive EOL care use included younger age, shorter disease duration, lower income quintiles, and rural residence. CONCLUSIONS: Over time, less women dying with gynecologic cancers in Ontario experienced death in hospital, and more accessed supportive care. However, the majority were still hospitalized and a significant proportion received aggressive care in the final 30 days of life.

Assessing the application of continuity of care indices in the last year of life: a retrospective population-based study.

Context: Most people spend the majority of their last year of life at home or in a home-like setting, receiving outpatient healthcare. Increasing numbers of physicians and teams, including palliative care providers, may become involved in care in addition to a usual provider such as a family physician. Continuity of care (CoC) near the end of life, although considered a marker of quality of care, may be interrupted despite the provision of high-quality care. Objective: To describe continuity of outpatient physician care in the last 12 months of life and determine patient and illness-related factors associated with high continuity. Study Design: Retrospective cohort study. Datasets: Linked population-based health administrative databases for Ontario, Canada, held at ICES. Population: Decedents aged 19 years or older, who died between January 1, 2013, and December 31, 2017. Outcome Measures: Continuity of care scores for the last 12 months of life, using the Usual Provider continuity (UPC), Bice-Boxerman continuity (CoC), and Sequential Continuity (SECON) indices. Multivariate models were used to determine factors associated with higher continuity scores (>= 0.75). Results: Decedents (n=322,445) were on average 76.3 years of age, 47.8% were female, and 13.2% resided in rural regions. Decedents had a mean of 16.2 outpatient physician encounters in the last year of life, from a mean of 3.8 different physician specialties. Mean continuity indices' scores (1 being perfect) were low: UPC= 0.36, CoC= 0.31, and SECON= 0.37. Proportions of decedents with high continuity were: UPC= 12.6%, CoC= 9.6%, and SECON= 12.9%. Decedents who experienced a terminal illness (i.e., cancer) end-of-life trajectory were least likely to experience high UPC (OR= 0.32; 95% CI= 0.30, 0.34). Having six or more comorbidities (OR= 0.65; 95% CI= 0.63, 0.66), and being in the highest quintile of outpatient physician encounters (i.e., >22 visits) (OR= 0.28; 95% CI= 0.27, 0.29) were also negatively associated with high UPC. Results were similar for other indices. Conclusions: Decedents experience low continuity of outpatient physician care in the last year of life, especially those with cancer, comorbidities, and frequent physician visits. Modifications to existing indices may be needed to serve as end-of-life care quality indicators.

A retrospective cohort study examining health care utilization patterns in individuals diagnosed with an eating disorder in childhood and/or adolescence.

OBJECTIVE: This study examined a 2-year period following an eating disorder (ED) diagnosis in order to determine patterns of health care utilization. METHOD: We conducted a retrospective cohort study of children (n = 1560) diagnosed with an ED between 2000 and 2017. The ED diagnosis was made at a tertiary level hospital for children and adolescents presenting for outpatient assessment by specialist adolescent medicine physicians and recorded in a program database over this period of time. We then created three sex- and age-matched comparison cohorts using provincial health administrative databases including: a general population cohort, a diabetes cohort (to compare nonmental health care utilization) and a mood disorder cohort (to compare mental health care utilization). Outcomes included hospitalizations, emergency department visits, as well as general practitioner, psychiatrist, and pediatrician visits. Odds ratios (dichotomous outcomes) and rate ratios (continuous outcomes) were calculated. RESULTS: Compared to the general population cohort, the ED cohort had higher odds and rates of all types of health care utilization. Compared to the diabetes cohort, the ED cohort had higher odds of nonmental health-related admissions (OR 1.45, 95% CI 1.09-1.95) and higher rates of nonmental health-related emergency department visits (RR 1.59, 95% CI 1.18-2.13). Compared to the mood disorder cohort, the ED cohort had higher rates of pediatrician visits, which were mental health-related (RR 14.88, 95% CI 10.64-20.82), however most other types of mental health service utilization were lower. DISCUSSION: These patterns indicate that the service needs of young people diagnosed with EDs are higher than those with diabetes with respect to nonmental health admissions and emergency department visits, while in terms of mental health service utilization, there appears to be a lack of use of mental health services compared to youth with mood disorders with the exception of pediatrician mental health visits. These findings must be interpreted in the context of under-detection and under-treatment of EDs. PUBLIC SIGNIFICANCE STATEMENT: Our study found that the health service needs of young people with EDs are higher than those with diabetes with respect to admissions and emergency department visits, while there appears to be a lack of use of mental health services compared to youth with mood disorders with the exception of pediatrician mental health visits.

Health care utilization and costs following Kawasaki disease.

Objectives: Kawasaki disease (KD) is a common childhood vasculitis with increasing incidence in Canada. Acute KD hospitalizations are associated with high health care costs. However, there is minimal health care utilization data following initial hospitalization. Our objective was to determine rates of health care utilization and costs following KD diagnosis. Methods: We used population-based health administrative databases to identify all children (0 to 18 years) hospitalized for KD in Ontario between 1995 and 2018. Each case was matched to 100 nonexposed comparators by age, sex, and index year. Follow-up continued until death or March 2019. Our primary outcomes were rates of hospitalization, emergency department (ED), and outpatient physician visits. Our secondary outcomes were sector-specific and total health care costs. Results: We compared 4,597 KD cases to 459,700 matched comparators. KD cases had higher rates of hospitalization (adjusted rate ratio 2.07, 95%CI 2.00 to 2.15), outpatient visits (1.30, 95%CI 1.28 to 1.33), and ED visits (1.22, 95%CI 1.18 to 1.26) throughout follow-up. Within 1 year post-discharge, 717 (15.6%) KD cases were re-hospitalized, 4,587 (99.8%) had ≥1 outpatient physician visit and 1,695 (45.5%) had ≥1 ED visit. KD cases had higher composite health care costs post-discharge (e.g., median cost within 1 year: $2466 CAD [KD cases] versus $234 [comparators]). Total health care costs for KD cases, respectively, were $13.9 million within 1 year post-discharge and $54.8 million throughout follow-up (versus $2.2 million and $23.9 million for an equivalent number of comparators). Conclusions: Following diagnosis, KD cases had higher rates of health care utilization and costs versus nonexposed children. The rising incidence and costs associated with KD could place a significant burden on health care systems.

Incidence and short-term outcomes of Kawasaki disease.

OBJECTIVE: Kawasaki disease (KD) is a childhood vasculitis with conflicting reported North American trends in incidence and patient characteristics. OBJECTIVES: (1) determine KD incidence between 1995 and 2017; (2) compare patient characteristics by era and age group; (3) determine complication and cardiovascular follow-up rates. METHODS: We used population-based health administrative data to identify children (0-18 yr) hospitalized with KD in Ontario, Canada between 1995 and 2017. We excluded children with prior KD diagnosis or incomplete records. We determined the annualized incidence and follow-up trends. RESULTS: KD was diagnosed in 4,346 children between 1995 and 2017. Annual KD incidence was 22.0 (<5 yr), 6.1 (5-9 yr), and 0.6 (10-18 yr) per 100,000 children. KD incidence increased significantly for all age groups, including from 18.4 to 25.0 cases per 100,000 children <5 yr. Ninety-day mortality occurred in ≤5 children (≤0.1%). Coronary artery aneurysm (CAA) occurred in 106 children (2.4%, 95% confidence interval 2.0-2.9) during admission and 151 (3.5%, 95% confidence interval 3.0-4.1) during 11-year median follow-up. Children 10-18 yr had longer hospitalizations (4.3 vs. 3.5 days, p = 0.003) and more CAA (7.4% vs. 3.4%, p = 0.007). By 1-year post-diagnosis, 3970 (91.3%) and 2576 (59.3%) children had echocardiography and cardiology follow-up, respectively. CONCLUSIONS: KD incidence is increasing in Ontario, with greater healthcare utilization from hospitalizations and subsequent follow-up. IMPACT: 4346 children were hospitalized for Kawasaki disease over 22 years in Ontario, and Kawasaki disease incidence increased significantly for all age groups, males and females. Older children (10-18 years) had longer hospital length of stay, more PICU admissions and more frequent coronary artery aneurysms. Nearly all children with Kawasaki disease had follow-up echocardiography within 1 year.

Advance Directives Change Frequently in Nursing Home Residents.

OBJECTIVES: To describe the rate, timing, and pattern of changes in advance directives (ADs) of do not resuscitate (DNR) and do not hospitalize (DNH) orders among new admissions to nursing homes (NHs). DESIGN: A retrospective cohort study. SETTING AND PARTICIPANTS: Admissions to all publicly funded NHs in Ontario, Canada, between January 1, 2013, and December 31, 2017. METHODS: Residents were followed until discharged from incident NH stay, death, or were still present at the end of study (December 31, 2019). They were categorized into 3 mutually exclusive baseline composite AD groups: Full Code, DNR Only, and DNR+DNH. We used Poisson regression models to estimate the incidence rate ratios of AD change between different AD groups and different decision makers for personal care, adjusted for baseline clinical and sociodemographic variables. RESULTS: A total of 102,541 NH residents were eligible for inclusion. Residents with at least 1 AD change accounted for 46% of Full Code, 30% of DNR Only, and 25% of DNR+DNH group. Median time to first AD change ranged between 26 and 55 weeks. For Full Code and DNR Only residents, the most frequent change was to an AD 1 level lower in aggressiveness or intervention, whereas for DNR+DNH residents the most frequent change was to DNR Only. About 16% of residents had 2 or more AD changes during their stay. After controlling for covariates, residents with a DNR-only order or DNR+DNH orders at admission and those with a surrogate decision maker were associated with lower AD change rates. CONCLUSIONS AND IMPLICATIONS: Measuring AD adherence rates that are documented only at a particular time often underestimates the dynamics of AD changes during a resident's stay and results in an inaccurate measure of the effectiveness of AD on resident care. There should be more frequent reviews of ADs as they are quite dynamic. Mandatory review after an acute change in a resident's health would ensure that ADs are current.

Sex-Based Analysis of Quality Indicators of End-of-Life Care in Gastrointestinal Malignancies.

Indices of aggressive or supportive end-of-life (EOL) care are used to evaluate health services quality. Disparities according to sex were previously described, with studies showing that male sex is associated with aggressive EOL care. This is a secondary analysis of 69,983 patients who died of a GI malignancy in Ontario between 2006 and 2018. Quality indices from the last 14-30 days of life and aggregate measures for aggressive and supportive EOL care were derived from administrative data. Hospitalizations, emergency department use, intensive care unit admissions, and receipt of chemotherapy were considered indices of aggressive care, while physician house call and palliative home care were considered indices of supportive care. Overall, a smaller proportion of females experienced aggressive care at EOL (14.3% vs. 19.0%, standardized difference = 0.13, where ≥0.1 is a meaningful difference). Over time, rates of aggressive care were stable, while rates of supportive care increased for both sexes. Logistic regression showed that younger females (ages 18-39) had increased odds of experiencing aggressive EOL care (OR 1.71, 95% CI 1.30-2.25), but there was no such association for males. Quality of EOL care varies according to sex, with a smaller proportion of females experiencing aggressive EOL care.

The relationship between patient experience and real-world digital health access in primary care: A population-based cross-sectional study.

Implementing digital health technologies in primary care is anticipated to improve patient experience. We examined the relationships between patient experience and digital health access in primary care settings in Ontario, Canada. We conducted a retrospective cross-sectional study using patient responses to the Health Care Experience Survey linked to health and administrative data between April 2019-February 2020. We measured patient experience by summarizing HCES questions. We used multivariable logistic regression stratified by the number of primary care visits to investigate associations between patient experience with digital health access and moderating variables. Our cohort included 2,692 Ontario adults, of which 63.0% accessed telehealth, 2.6% viewed medical records online, and 3.6% booked appointments online. Although patients reported overwhelmingly positive experiences, we found no consistent relationship with digital health access. Online appointment booking access was associated with lower odds of poor experience for patients with three or more primary care visits in the past 12 months (adjusted odds ratio 0.16, 95% CI 0.02-0.56). Younger age, tight financial circumstances, English as a second language, and knowing their primary care provider for fewer years had greater odds of poor patient experience. In 2019/2020, we found limited uptake of digital health in primary care and no clear association between real-world digital health adoption and patient experience in Ontario. Our findings provide an essential context for ensuing rapid shifts in digital health adoption during the COVID-19 pandemic, serving as a baseline to reexamine subsequent improvements in patient experience.

Treatment Pattern, Healthcare Resource Utilization and Symptom Burden Among Patients with Triple Class Exposed Multiple Myeloma: A Population-Based Cohort Study.

PURPOSE: This study aims to describe the treatment patterns, outcomes, health care utilization and symptom burden of triple class exposed (TCE) relapsed/refractory patents with multiple myeloma (MM) receiving a subsequent line of treatment (LOT). METHODS: This is a retrospective observational cohort study using administrative databases in Ontario, Canada. Outcomes were captured for TCE patients receiving a subsequent LOT and included: treatment regimen details, time to next treatment (TTNT), overall survival (OS), health care utilization, palliative care referral, and patient reported symptoms. RESULTS: Of the 16,777 patients diagnosed with MM between 2007-2021 in Ontario, 1358 (8%) patients were classified as TCE. Among the TCE MM patients, 489 (36%) received a subsequent LOT. The two most commonly administered therapies post TCE were carfilzomib/dexamethasone (n = 111, 22%) and pomalidomide/dexamethasone(n = 95, 19%). Median TTNT was 1.7 months (95%CI 1.2-2.4 months) and median OS 12.8 months (95%CI 10.8-16.5). Healthcare utilization was high with 276 (56%) of patients evaluated in an emergency department (ED) or admitted to hospital. There was high symptom burden as reported by patients with moderate-severe impairment in well-being, fatigue, pain and drowsiness noted in greater than 25% of the cohort. Palliative care referrals rates were low with only 10% (n = 48) patients referred to palliative care. Among the patients that died during study follow up, the majority died in hospital (n = 147,44%). CONCLUSION: Our study reports one of the largest series of real-world TCE patients published and demonstrates the poor outcomes of TCE patients receiving a subsequent LOT.
