The relationship between patient experience and real-world digital health access in primary care: A population-based cross-sectional study. PLoS One 2024; 19:e0299005. [PMID: 38713719 DOI: 10.1371/journal.pone.0299005] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/06/2023] [Accepted: 02/04/2024] [Indexed: 05/09/2024] Open
Abstract
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.

A Prognostic Survival Model Incorporating Patient-Reported Outcomes for Transplant-Ineligible Patients With Multiple Myeloma. Oncologist 2024:oyae041. [PMID: 38636951 DOI: 10.1093/oncolo/oyae041] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/29/2023] [Accepted: 02/14/2024] [Indexed: 04/20/2024] Open
Abstract
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.

Sex-Based Analysis of Quality Indicators of End-of-Life Care in Gastrointestinal Malignancies. Curr Oncol 2024; 31:1170-1182. [PMID: 38534920 PMCID: PMC10969381 DOI: 10.3390/curroncol31030087] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 02/05/2024] [Accepted: 02/16/2024] [Indexed: 05/26/2024] Open
Abstract
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.

Development and validation of thromboembolism diagnostic algorithms in children with cancer from real-world data. Pediatr Res 2024:10.1038/s41390-024-03082-x. [PMID: 38388822 DOI: 10.1038/s41390-024-03082-x] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/15/2023] [Revised: 01/03/2024] [Accepted: 01/21/2024] [Indexed: 02/24/2024]
Abstract
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.

Treatment Pattern, Healthcare Resource Utilization and Symptom Burden Among Patients with Triple Class Exposed Multiple Myeloma: A Population-Based Cohort Study. CLINICAL LYMPHOMA, MYELOMA & LEUKEMIA 2024:S2152-2650(24)00065-X. [PMID: 38431522 DOI: 10.1016/j.clml.2024.02.006] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/09/2024] [Accepted: 02/09/2024] [Indexed: 03/05/2024]
Abstract
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.

Cancer-specific mortality in multiple myeloma: a population-based retrospective cohort study. Haematologica 2023; 108:3384-3391.

Abstract
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.

Abstract
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.

A diagnostic subgroup comparison of health care utilization patterns in individuals with eating disorders diagnosed in childhood and/or adolescence. Int J Eat Disord 2023; 56:1919-1930. [PMID: 37449455 DOI: 10.1002/eat.24024] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/18/2023] [Revised: 07/03/2023] [Accepted: 07/04/2023] [Indexed: 07/18/2023]
Abstract
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.

Abstract
BACKGROUND Challenges in timely access to one's usual primary care physician and the ongoing use of walk-in clinics have been major health policy issues in Ontario for over a decade. We sought to determine the association between patient-reported timely access to their usual primary care physician or clinic and their use of walk-in clinics. METHODS We conducted a cross-sectional study of Ontario residents who had a primary care physician by linking population-based administrative data to Ontario's Health Care Experience Survey, collected between 2013 and 2020. We described sociodemographic characteristics and health care use for users of walk-in clinics and nonusers. We measured the adjusted association between self-reported same-day or next-day access and after-hours access to usual primary care physicians or clinics and the use of walk-in clinics in the previous 12 months. RESULTS Of the 60 935 total responses from people who had a primary care physician, 16 166 (weighted 28.6%, unweighted 26.5%) reported visiting a walk-in clinic in the previous 12 months. Compared with nonusers, those who used walk-in clinics were predominantly younger, lived in large and medium-sized urban areas and reported a tight, very tight or poor financial situation. Respondents who reported poor same-day or next-day access to their primary care physician or clinic were more likely to report having attended a walk-in clinic in the previous 12 months than those with better access (adjusted odds ratio [OR] 1.23, 95% confidence interval [Cl] 1.13-1.34). Those who reported being unaware that their primary care physician offered after-hours care had a higher likelihood of going to a walk-in clinic (adjusted OR 1.14, 95% Cl 1.07-1.21). INTERPRETATION In this population-based health survey, patient-reported use of walk-in clinics was associated with a reported lack of access to same-day or next-day care and unawareness of after-hours care by respondents' usual primary care physicians. These findings could inform policies to improve access to primary care, while preserving care continuity.

Abstract
OBJECTIVE To describe the timing of involvement of various physician specialties over the last year of life across different levels of primary care physician continuity for differing causes of death. METHODS We conducted a retrospective cohort study of adults who died in Ontario, Canada, between 1 January 2013 and 31 December 2018, using linked population level health administrative data. Outcomes were median days between death and first and last outpatient palliative care specialist encounter, last outpatient encounter with other specialists and with the usual primary care physician. These were calculated by tertile of score on the Usual Provider Continuity Index, defined as the proportion of outpatient physician encounters with the patient's primary care physician. RESULTS Patients' (n=395 839) mean age at death was 76 years. With increasing category of usual primary care physician continuity, a larger proportion were palliative care generalists, palliative care specialist involvement decreased in duration and was concentrated closer to death, the primary care physician was involved closer to death, and other specialist physicians ceased involvement earlier. For patients with cancer, palliative care specialist involvement was longer than for other patients. CONCLUSIONS Compared with patients with lower continuity, those with higher usual provider continuity were more likely to have a primary care physician involved closer to death providing generalist palliative care.

Abstract
OBJECTIVES To describe variations in the receipt of potentially inappropriate interventions in the last 100 days of life of patients with cancer according to patient characteristics and cancer site. METHODS We conducted a population-based retrospective cohort study of cancer decedents in Ontario, Canada who died between 1 January 2013 and 31 December 2018. Potentially inappropriate interventions, including chemotherapy, major surgery, intensive care unit admission, cardiopulmonary resuscitation, defibrillation, dialysis, percutaneous coronary intervention, mechanical ventilation, feeding tube placement, blood transfusion and bronchoscopy, were captured via hospital discharge records. We used Poisson regression to examine associations between interventions and decedent age, sex, rurality, income and cancer site. RESULTS Among 151 618 decedents, 81.3% received at least one intervention, and 21.4% received 3+ different interventions. Older patients (age 95-105 years vs 19-44 years, rate ratio (RR) 0.36, 95% CI 0.34 to 0.38) and women (RR 0.94, 95% CI 0.93 to 0.94) had lower intervention rates. Rural patients (RR 1.09, 95% CI 1.08 to 1.10), individuals in the highest area-level income quintile (vs lowest income quintile RR 1.02, 95% CI 1.01 to 1.04), and patients with pancreatic cancer (vs colorectal cancer RR 1.10, 95% CI 1.07 to 1.12) had higher intervention rates. CONCLUSIONS Potentially inappropriate interventions were common in the last 100 days of life of cancer decedents. Variations in interventions may reflect differences in prognostic awareness, healthcare access, and care preferences and quality. Earlier identification of patients' palliative care needs and involvement of palliative care specialists may help reduce the use of these interventions at the end of life.

Abstract
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.

Abstract
Background Pancreatic adenocarcinoma (PAC) is a deadly disease with an overall 5-year survival of less than 8%. The current literature on patient outcomes are limited by small samples sizes and patients enrolled in clinical trials. There are no prognostic tools for patients with pancreatic cancer. Purpose To develop a prognostic survival model for patients with pancreatic cancer Method All patients with a diagnosis of pancreatic cancer cancer from January 2007 to December 2020 were identified through the Ontario Cancer Registry. The primary outcome was survival. The cohort was used to develop a multivariable cox proportional hazards regression model with baseline characteristics under a backward stepwise variable selection process to predict the risk of mortality. Covariates included patient age, sex, tumour location, cancer stage, treatment types, distance to a cancer centre, hospitalizations, comorbidities, access to family physician, and symptoms as captured using the Edmonton Symptom Assessment System datasets. Result(s) There was a total of 17,450 pancreatic cancer patients in the cohort, 48% of which were female and the mean age was 72 years. 44% of patients presented with a tumor in the head of the pancreas. Among those with stage data (44%), 24% were stage IV at diagnosis. Mean survival was approximately 0.7 years. Approximately 60% were hospitalized in the 3 months prior to diagnosis. Almost all patients had a family doctor rostered (95%). In multivariate analysis, key predictors of survival assessed at the time of diagnosis were age, sex, tumour location in the pancreas, stage at diagnosis, pain, appetite functional status and treatment choice (all p<0.001). Using these variables, we created a prediction model that can estimate one-year probability of death with high discrimination (area under the curve = 0.82, c-statistic 0.76). Conclusion(s) Our model accurately predicts one-year pancreatic cancer survival risk using clinical symptom and performance status data. The model has the potential to be a useful prognostic tool that can be completed by patients and their caregivers in support of patient-centered care.

Abstract
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.

Trends in quality indicators of end-of-life care for women with gynecologic malignancies in Ontario, Canada. Gynecol Oncol 2022; 167:247-255. [PMID: 36163056 DOI: 10.1016/j.ygyno.2022.09.008] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/30/2022] [Revised: 08/18/2022] [Accepted: 09/07/2022] [Indexed: 11/23/2022]
Abstract
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.

A retrospective cohort study examining health care utilization patterns in individuals diagnosed with an eating disorder in childhood and/or adolescence. Int J Eat Disord 2022; 55:1316-1330. [PMID: 35920409 DOI: 10.1002/eat.23789] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/19/2022] [Revised: 07/15/2022] [Accepted: 07/15/2022] [Indexed: 11/09/2022]
Abstract
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.

Abstract
ObjectivesThe objective of this study was to describe the receipt of potentially non-beneficial interventions in the last 100 days of life of cancer patients and to examine variations in these interventions according to patient characteristics and cancer site.
ApproachWe conducted a population-based retrospective cohort study of all adults age 18+ who died of cancer in Ontario, Canada between January 1, 2013 and December 31, 2017 using linked administrative health data held at ICES. Potentially non-beneficial interventions were captured via hospital discharge records and included chemotherapy, major surgery, intensive care unit admission, cardiopulmonary resuscitation, defibrillation, dialysis, percutaneous coronary intervention, mechanical ventilation, feeding tube placement, blood transfusion and bronchoscopy. We used bivariate analyses and multivariable Poisson regression to examine associations between the receipt of interventions and decedent age, sex, rurality, area-level income, and cancer site.
ResultsAmong the 125,755 decedents, the most common intervention was blood transfusion (18.1%) and major surgery (12.8%); 23.8% received no interventions, while 14% of decedents received 3+ interventions. Lower intervention rates were observed in older patients (adjusted rate ratio (RR) 0.46, 95% confidence interval (CI) 0.44-0.49 for age 95+ vs. 19-44), females (RR 0.93, 95% CI 0.92-0.94), and individuals living in higher income areas (RR 0.96, 95% CI 0.95-0.98 for highest vs. lowest income quintile). Higher intervention rates were observed in rural patients (RR 1.13, 95% CI 1.11-1.14). Patients with pancreatic cancer had the highest intervention rate (RR 1.13, 95% CI 1.10-1.16), while breast cancer patients had the lowest intervention rate (RR 0.86, 95% CI 0.84-0.89) compared to colorectal cancer patients.
ConclusionPotentially non-beneficial interventions were common in the last 100 days of life of patients with cancer. Variations in interventions across patient demographics and cancer site may reflect differences in healthcare access, end-of-life care preferences, patients’ prognostic awareness, and disease factors.

Quality of end-of-life care in multiple myeloma: A 13-year analysis of a population-based cohort in Ontario, Canada. Br J Haematol 2022; 199:688-695. [PMID: 35949180 DOI: 10.1111/bjh.18401] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2022] [Revised: 07/06/2022] [Accepted: 07/26/2022] [Indexed: 11/30/2022]
Abstract
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.

Abstract
12031 Background: Despite treatment advances, multiple myeloma (MM) remains a significant source of morbidity and mortality. The end of life for patients with MM has not previously been examined within the context of a population-based cohort in a publicly funded health system. Methods: We retrospectively analyzed patients with death attributable to MM between 2006-2018 using ICES linked databases in the public health care system in Ontario, Canada. Aggressive care was defined as two or more emergency department visits in the last 30 days before death, at least two new hospitalizations within 30 days of death, or an ICU admission within 30 days of death. Supportive care was defined as physician house call 2 weeks before death, or a palliative nursing or personal support visit at home in last 30 days before death. Multivariable logistic regression models were used to assess for factors predisposing to aggressive or supportive care. Patients were stratified based on receipt of autologous stem cell transplant (ASCT). Results: In total, 5095 patients were included (Table). Overall, 23.2% of patients received chemotherapy in last two weeks of life and 55.6% of patients died in the hospital. Most patients were admitted to hospital within the last 30 days of life (73.4%:ASCT cohort, 61.4%:non-ASCT cohort). A minority received aggressive care at end of life (28.3%:ASCT cohort, 20.4%:non-ASCT cohort), and a majority received supportive care at end of life (65.4%:ASCT cohort, 61.5%:non-ASCT cohort). Multivariate regression models showed that patients ≥ 80 years (compared to 60-69) were less likely to receive aggressive care (OR=0.54, 95% CI=0.42-0.68), and those with residence in smaller size community of < 10,000 were more likely to receive aggressive care (OR=1.89, 95% CI=1.5-2.4). Supportive care was significantly less likely to be received by patients (OR=0.72, 95% CI= 0.59 to 0.88) and more likely to be received by patients aged 18-49 (OR=1.9, 95% CI=1.2-3.1). Neighbourhoods with lowest income quintiles (OR=0.65, 95% CI=0.53-0.78) were less likely to receive supportive care. When trended over time, patients receiving supportive care at end of life increased (56.0% in 2006 to 70.3% in 2018). Conclusions: We demonstrate that despite improvements over time, a substantial number of patients with MM experience aggressive care and hospitalizations at the end of life. Despite this being a publicly funded system, disparities in end-of-life care based on age, income and area of residence are present.[Table: see text]

A more accurate approach to define abortion cohorts using linked administrative data: an application to Ontario, Canada. Int J Popul Data Sci 2022; 7:1700.

Abstract
Background The shifting landscape of abortion care from a hospital-only to a distributed service including primary care has implications for how to identify abortion cohorts for research and surveillance. The objectives of this study were to 1) create an improved approach to define abortion cohorts using linked administrative data sets and 2) evaluate the performance of this approach for abortion surveillance compared with standard approaches. Methods We applied four principles to identify induced abortion cohorts when some services are delivered beyond hospital settings; 1) exclude early pregnancy losses and postpartum procedures; 2) use multiple data sources; 3) define episodes of care; 4) apply a hierarchical algorithm to determine abortion date to a population-based cohort of all abortion events in Ontario (Canada) from January 1, 2018-March 15, 2020. We calculated risk differences (RD, with 95% confidence intervals) comparing the proportion of medication vs. surgical, first vs. second trimester, and complication incidence applying these principles vs. standard approaches. Results Hospital-only data (versus multiple data sources) underestimated the frequency of medication abortion (16.1% vs. 31.4%; RD -15.3% [-14.3, -16.3]) and first-trimester abortion (82.1% vs. 94.5%; RD -12.8 [-11.4, 13.4]) and overestimated incidence of abortion complication (2.9% vs. 0.69%; RD 2.2% [1.8, 2.7]). An unlinked (versus linked) approach underestimated the frequency of abortion complications (0.19% vs 0.69%, -RD 0.50% [-0.44--0.56]). Including (versus excluding) abortions following early pregnancy loss or delivery events increased the estimated incidence of abortion complications (1.29% vs. 0.69%, RD 0.60% [0.51-0.69]. Conclusion New methods are required to accurately identify abortion cohorts for surveillance or research. When legal or regulatory approaches to medication abortion evolve to enable abortion in primary care or office-based settings, hospital-based surveillance systems will become incomplete and biased; to continue valid and complete abortion surveillance, methods must be adjusted to ensure complete capture of procedures across all settings.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
BACKGROUND Kawasaki disease (KD) incidence is increasing in Ontario. Cardiovascular sequelae following KD are well-described. However, there are limited data on non-cardiovascular outcomes. OBJECTIVES To determine the risk of hearing loss, anxiety, developmental disorders, intellectual disabilities and attention-deficit/hyperactivity disorder (ADHD) among KD survivors vs. non-exposed children. METHODS We included all Ontario children (≤18 yr) surviving hospitalization with a KD diagnosis between 1995 and 2018, using population-based health administrative databases. We excluded children with prior KD diagnoses and non-residents. KD cases were matched with 100 non-exposed children by age, sex and year. Follow-up continued until death or March 2019. We calculated the prevalence, incidence and adjusted hazard ratios (aHR [95%CI]) of outcomes between 0-1 yr, 1-5 yr, 5-10 yr and >10 yr follow-up. RESULTS Among 4597 KD survivors, 364 (7.9%) were diagnosed with hearing loss, 1213 (26.4%) anxiety disorders, 398 (8.7%) developmental disorders, 51 (1.1%) intellectual disability and 21 (0.5%) ADHD, during median 11 year follow-up. Compared to 459,700 non-exposed children, KD survivors were not at increased risk of hearing loss after adjustment for potential confounders. KD survivors were at increased risk of anxiety disorders between 0-1 yr (aHR 1.75 [1.46-2.10]), 1-5 yr (aHR 1.13 [1.01-1.28]), 5-10 yr (aHR 1.14 [1.03-1.28]) and >10 yr (aHR 1.11 [1.02-1.22]); developmental disorders between 0-1 yr (aHR 1.49 [1.28-1.74]) and 1-5 yr (aHR 1.19 [1.02-1.40]); intellectual disabilities >10 yr (aHR 2.36 [1.36-4.10]); and ADHD >10 yr (aHR 2.01 [1.14-3.57]). CONCLUSIONS KD survivors are at increased risk of being diagnosed with anxiety disorders sooner, being diagnosed with developmental disorders between 0 and 5 yr and being diagnosed with intellectual disabilities or ADHD >10 yr after KD diagnosis. This may justify enhanced developmental and audiological surveillance of KD survivors.

Effect of patient-centered transitional care services on patient-reported outcomes in heart failure: sex-specific analysis of the PACT-HF randomized controlled trial. Eur J Heart Fail 2021; 23:1488-1498. [PMID: 34302417 DOI: 10.1002/ejhf.2312] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/31/2021] [Revised: 07/10/2021] [Accepted: 07/20/2021] [Indexed: 12/28/2022] Open
Abstract
AIMS We assessed the effect of transitional care on patient-reported outcomes (PROs) in women and men hospitalized for heart failure. METHODS AND RESULTS In this sex-specific analysis of a stepped wedge cluster randomized trial in Canada, the effect of a patient-centered transitional care model was tested on pre-specified PROs of discharge preparedness (B-PREPARED score, range 0-22), quality of transition [Care Transitions Measure-3 (CTM-3) score, range 0-100], and health-related quality of life (HRQOL) (EQ-5D-5L, range 0-1). Among 986 patients (47.4% women), B-PREPARED at 6 weeks was greater with the intervention than usual care [mean difference (MD) 4.01 (95% confidence interval-CI 2.90-5.12); P < 0.001], with no sex differences (P sex-interaction = 0.24). CTM-3 at 6 weeks was greater with the intervention than usual care [MD 10.52 (95% CI 6.00-15.04); P < 0.001], with no sex differences (P sex-interaction = 0.69). EQ-5D-5L was greater with intervention than usual care at discharge [MD 0.17 (95% CI 0.12-0.22); P < 0.001], 6 weeks [MD 0.06 (95% CI 0.01-0.12); P = 0.02], and 6 months [MD 0.05 (95% CI -0.01 to 0.12); P = 0.09], although the 6-month difference was not statistically significant. At discharge, women reported lower EQ-5D-5L but experienced significantly greater treatment benefit than men (P sex-interaction = 0.02). Treatment effect on EQ-5D-5L was numerically greater in women than men at 6 weeks and 6 months, but there were no significant sex differences (P sex-interaction 0.18 and 0.19, respectively). CONCLUSION A patient-centered transitional care model improved discharge preparedness, transition quality, and HRQOL in the weeks following heart failure hospitalization, with effects largely consistent in women and men. However, women reported lower HRQOL and experienced greater treatment benefit in this endpoint than men at hospital discharge. CLINICAL TRIAL REGISTRATION ClinicalTrials.gov NCT02112227.
