Background: Huntington’s disease (HD) is a rare, genetic, neurodegenerative disease. Obtaining population-level data on epidemiology and disease management is challenging. Objective: To investigate the epidemiology, clinical manifestations, treatment, and healthcare utilization of patients with HD in Israel. Methods: Retrospective population-based cohort study, including 20 years of routinely collected data from Maccabi Healthcare Services, an insurer and healthcare provider for one-quarter of the Israeli population. Results: The study cohort included 109 adult patients (aged ≥18 years) diagnosed with HD, with mean age of 49.9 years and 56%females. The most common HD-related conditions were anxiety (40%), behavioral problems (34%), sleep disorders (21%), and falls (13%). Annual incidence rates for HD ranged from 0.17 to 1.34 per 100,000 from 2000 to 2018; the 2018 crude prevalence in adults was 4.36 per 100,000. Median survival from diagnosis was approximately 12 years (95%CI: 10.4–15.3). The most frequent symptomatic treatments were antidepressants (69%), antipsychotics (63%), and tetrabenazine (63%), the only drug approved for the treatment of HD chorea in Israel during the examined period. Patterns of healthcare utilization changed as disease duration increased, reflected by increased frequency of emergency department visits and home visits. Conclusion: This retrospective population-based study provides insights into the prevalence, incidence, clinical profile, survival, and resource utilization of patients with HD in ethnically diverse Israel. The findings in this study are generally consistent with the international literature and demonstrate the value of routinely collected healthcare data as a complementary resource in HD research.

Maternal smoking is established to cause adverse birth outcomes, but evidence considering maternal smoking change across successive pregnancies is sparse. We examined the association between self-reported maternal smoking during and between the first two pregnancies with the odds of small for gestational age (SGA) birth (<10th percentile) in the second infant. Records for the first two pregnancies for 16791 women within the SLOPE (Studying Lifecourse Obesity PrEdictors) study were analysed. This is a population-based cohort of prospectively collected anonymised antenatal and birth healthcare data (2003–2018) in Hampshire, UK. Logistic regression was used to relate maternal smoking change to the odds of SGA birth in the second infant. In the full sample, compared to never smokers, mothers smoking at the start of the first pregnancy had higher odds of SGA birth in the second pregnancy even where they stopped smoking before the first antenatal appointment for the second pregnancy (adjusted odds ratio (aOR) 1.50 [95% confidence interval 1.10, 2.03]). If a mother was not a smoker at the first antenatal appointment for either her first or her second pregnancy, but smoked later in her first pregnancy or between pregnancies, there was no evidence of increased risk of SGA birth in the second pregnancy compared to never smokers. A mother who smoked ten or more cigarettes a day at the start of both of her first two pregnancies had the highest odds of SGA birth (3.54 [2.55, 4.92]). Women who were not smoking at the start of the first pregnancy but who subsequently resumed/began smoking and smoked at the start of their second pregnancy, also had higher odds (2.11 [1.51, 2.95]) than never smokers. Smoking in the first pregnancy was associated with SGA birth in the second pregnancy, even if the mother quit by the confirmation of her second pregnancy.

Abstract Background The disease burden from cirrhosis is increasing worldwide. Refractory ascites (RA) is a complication of cirrhosis associated with poor prognosis if liver transplant is not an option. Serial large volume paracentesis (LVP) is the standard of care in the management of refractory ascites (RA) and outpatient LVP has been shown to be safe and cost effective. Epidemiologic data is lacking regarding the incidence of RA, or how patients with RA are managed in routine clinical practice. Aims To describe secular trends in the incidence of RA in Ontario from 2000–2017, and to describe physician provider types performing LVPs in the RA population in Ontario. Methods This retrospective, population-based cohort study uses routinely collected healthcare data from Ontario, Canada, housed at ICES. From January 1, 2000 to Dec 31, 2017 all adult patients with cirrhosis were identified using a validated case definition, and those with RA were identified based on the need for serial LVP. All LVP procedures were described based on patient demographics, local health integration network (LHIN), physician type (Gastroenterology [GI], Internal Medicine [IM], Interventional Radiology [IR], Emergency Medicine [ER], other) and albumin administration. Annual incidence rates (IR) of RA in patients with cirrhosis were calculated and compared using Poisson regression to calculate incident rate ratios (IRRs). Annual LVP volume by provider type and LHIN were calculated and differences were compared using chi-squared analysis. Results The overall incidence of RA in patients with cirrhosis remained relatively stable over the study period (IRR 1.01, 95% CI 1.00–1.02 P&lt;.001). The highest incidence of RA was in those with viral hepatitis and alcohol-related cirrhosis. A total of 90,126 LVPs were identified (median age 61 years [IQR 53–70], 69% male, median LVP per patient 24 [IQR 11–48], 15.8% received albumin infusion). The absolute numbers of LVPs more than tripled over the study period (12,047 in 1997–2002 vs. 37,437 in 2013–2017). GI performed the majority of LVPs (40.1%) followed by IR (22.4%), and IM (8.4%), but there was substantial variation based on location (Fig 1). Overall, the proportion performed by IR increased during the study (7.8% in 1997–2002 vs 30.8% in 2013–2017, P &lt;.001) while the proportion performed by GI decreased (50% 1997–2002 vs 33.1% 2013–2017, P&lt;.001). Conclusions The number of LVPs performed for RA have increased dramatically in Ontario over the past two decades, with the proportion being performed by GI physicians decreasing, while IR is increasing. Substantial variability exists across LHINs on the use of LVP, which may reflect differences in access to resources for LVP, or physician practice. Appropriate albumin use with LVP remains an area for potential quality improvement initiatives in the future.

ObjectivesTo characterise the sex-specific difference in the association between anthropometric changes and risk of diabetes in the general population in Canada.Setting and participantsFrom 2000 to 2008, Alberta’s Tomorrow Project (ATP) invited Alberta’s residents aged 35–69 years to a prospective cohort study. A total of 19 655 diabetes-free ATP participants having anthropometrics measured at the baseline and follow-ups were included.Design and outcome measuresA longitudinal study design was used to examine the association between anthropometric changes and risk of diabetes and the sex difference in this association. Changes in weight, body mass index (BMI), waist circumference (WC) and waist-hip-ratio (WHR) were calculated as the difference between baseline and follow-up measures. Diabetes cases were identified using the Canadian National Diabetes Surveillance System algorithm with administrative healthcare data (2000–2015) linked to the ATP cohort. The sex-specific association between anthropometric changes and incidence of diabetes were examined by multivariable Cox regression models.ResultsChanges in weight, BMI, WC and WHR over time were positively associated with incidence of diabetes in both men and women. The sex difference in risk of diabetes associated with 1 standard deviation (SD) increase in anthropometrics was 0.07 (95% CI −0.02 to 0.14) for weight, 0.08 (95% CI −0.03 to 0.17) for BMI, 0.07 (95% CI −0.02 to 0.15) for WC and 0.09 (95% CI 0.03 to 0.13) for WHR. Similar results were found in sex difference in the associations with changes per 5% and changes per categories (5% loss, ±5%, 5% gain).ConclusionsThe positive association between anthropometric changes and risk of diabetes was generally stronger in men than in women. However, this sex-specific difference of approximately 10% of the total risk associated with anthropometric changes had limited significance. For population-based public health programmes aiming to control obesity and incidence of diabetes, it may not be necessary to set up sex-specific goals for anthropometric reduction.

Health leaders and caregivers are focused on evidence-based data to drive care delivery and practice. Ensuring the health system is functioning effectively and efficiently and that patient outcomes are reaching expected targets are topics that permeate conversations at the local, provincial, and national levels. However, as many leaders have come to understand in recent years, healthcare data collection and producing meaningful, high-quality metrics is a complex set of tasks, requiring its own level of attention and dedicated resources. In the healthcare data realm, there are opportunities to learn from experience. One of these opportunities is the population-based cancer registry, which is one of the oldest examples of standardized data collection in the Canadian health system.

ABSTRACTObjectives Ontario, the most populous province in Canada, has a universal healthcare system that routinely collects health administrative data on its 13 million legal residents that is used for health research. Record linkage has become a vital tool for this research by enriching this data with the Immigration, Refugees and Citizenship Canada (IRCC) Permanent Resident database and the Office of the Registrar General’s Vital Statistics-Death (VSD) registry. Our objectives were to estimate linkage rates and compare characteristics of individuals in the linked versus unlinked files. Approach We used both deterministic and probabilistic linkage methods to link the IRCC database (1985-2012) and VSD registry (1990-2012) to the Ontario’s Registered Persons Database. Linkage rates were estimated and standardized differences were used to assess differences in socio-demographic and other characteristics between the linked and unlinked records. Results The overall linkage rates for the IRCC database and VSD registry were 86.4% and 96.2%, respectively. The majority (68.2%) of the record linkages in IRCC were achieved after the three deterministic passes with the remaining 18.2% being linked probabilistically. Similarly the majority (79.8%) of the record linkages in the ORGD were linked using deterministic record linkage and the remaining 16.3% were linked after probabilistic and manual review. Unlinked and linked files were similar for most characteristics, such as age and marital status for IRCC and sex and most causes of death for VSD. However, lower linkage rates were observed among people born in East Asia (78%) in the IRCC database and certain causes of death in the VSD registry, namely perinatal conditions (61.3%) and congenital anomalies (81.3%). Conclusion The linkages of immigration and vital statistics data to existing population-based healthcare data in Ontario, Canada will enable many novel cross-sectional and longitudinal studies to be conducted. Analytic techniques to account for sub-optimal linkage rates may be required in studies of certain ethnic groups or certain causes of death among children and infants.

Self Harm

BackgroundAccurate data on self-harm is crucial to suicide prevention efforts. It has been previously found that around twice as many people who self-harm seek help in primary care than in secondary care. Little is known about how contacts for self-harm differ across settings at a population level. This study utilised individual-level linked data across GP, Emergency Departments (ED), outpatients and hospital admissions examining contacts across settings and time by sex for self-harm in 10-24 year olds. MethodsA whole-population based e-cohort study of routinely collected healthcare data was conducted. Rates of self-harm across settings over time by sex were examined. Individuals were categorised based on the service(s) to which they presented. ResultsA total of 937,697 individuals aged 10-24 years contributed 5,369,794 person years of data from the 01.01.2003-30.09.2015. There were differences in self-harm contacts by demographic variables particularly with regards to sex and admissions to hospital following ED attendance. ConclusionThis is the first study to compare self-harm in people aged 10-24 years across primary care, EDs, and hospital settings in the UK. The high rates of self-harm in primary care and for young men in EDs highlight these as important settings for intervention. Understanding patterns of presentation will inform service planning and configuration for follow-up care and could inform tailored support, for example for males in ED. Linked data provides important evidence to support the development of interventions across healthcare settings.

10055 Background: Though hearing loss is a significant late effect among childhood cancer survivors, recent guidelines note insufficient evidence to quantify natural history or risk associated with specific exposures. We examined the long-term incidence and predictors of hearing loss requiring hearing amplification devices (HAD) using population-based healthcare data. Methods: In Ontario, Canada, HAD costs are subsidized by the provincial Assistive Devices Program (ADP). Ontario children age <18 years at cancer diagnosis between 1987-2016 were identified using a pediatric cancer registry and linked to ADP claims. The cumulative incidence of HAD use was compared between cases and matched controls. Patient, disease, and treatment predictors of HAD were examined. Results: We identified 11,842 cases and 59,210 matched controls. Cases were at higher risk of HAD [hazard ratio (HR) 12.8, 95% confidence interval (95CI) 9.8-16.7; p<0.001]. The cumulative incidence of HAD among survivors was 2.1% (95CI 1.7-2.5%) at 20-years and 6.4% (95CI 2.8-12.1%) at 30-years. 30-year incidence was highest in survivors of neuroblastoma (10.7%, 95CI 3.8-21.7%) and hepatoblastoma (16.2%, 95CI 8.6-26.0%). Predictors of HAD in multivariable analyses included age 0-4 years at diagnosis (vs. 5-9 years, HR 2.2, 95CI 1.4-3.3; p<0.001). Relative to no cisplatin exposure, patients receiving 1-200mg/m2 were not at greater risk, unlike those receiving higher cumulative doses (Table). Relative to no radiation, those receiving ≤32Gy were at no higher risk, unlike while those receiving >32Gy. Carboplatin exposure was not associated with HAD. Conclusions: Childhood cancer survivors are at elevated risk of requiring HAD which continues to rise between 20 and 30 years from diagnosis. Thresholds of cisplatin and radiation exposure exist above which risk substantially increases. Prolonged monitoring and trials of otoprotective agents are warranted in high-risk populations.
