RESUMO

Factors affecting intrauterine environment exerts influence on skeletal health and fracture risk in later life. Diabetes during pregnancy is known to influence birth weight and is associated with fetal overgrowth. However, the effects of maternal diabetes on fracture risk in offspring is unknown. This study was aimed to evaluate the association between maternal diabetes and fracture risk in offspring. Using population-based administrative health data for Manitoba, Canada, we identified deliveries complicated by gestational diabetes and type 2 diabetes between April 1, 1980 and March 31, 2020. The cohort was followed for a median of 15.8 years. The primary outcome was any incident fracture in offspring. Secondary outcomes were long bone upper extremity fracture, long bone lower extremity fracture, vertebral fracture, and any non-trauma fractures. Cox proportional hazard regression models were used to estimate fracture risk in offspring by maternal diabetes status adjusted for relevant covariates. Of 585 176 deliveries, 26 397 offspring were born to women with diabetes (3.0% gestational diabetes and 1.5% type 2 diabetes) and 558 779 were born to women without diabetes. The adjusted risk for any fracture was 7% (HR 1.07; 95% CI, 2.7-11.5%) higher in offspring of mothers with diabetes than offspring of mothers without diabetes. Types of fractures were similar between the two groups with a predominance of long-bone upper extremity fractures. In conclusion, maternal diabetes was associated with a modest increase in fracture risk in offspring. Longitudinal prospective studies are needed to understand intrauterine and post-natal factors that may influence fracture risk in offspring of mothers with diabetes.

RESUMO

AIM: To describe the incidence and prevalence of type 2 diabetes in children in Manitoba over a ten-year period. METHODS: Population-based, provincial databases were linked to calculate the incidence and prevalence of type 2 diabetes in children < 18 years of age in Manitoba from 2009-10 to 2017-18. First Nation and all other Manitoban children are described separately. RESULTS: The incidence of type 2 diabetes increased from 16.0/100,000/year in 2009-10 to 31‧1/100,000/year in 2017-18 (p < 0.001). For First Nation children, the incidence increased from 73‧4 to 121‧2/100,000/year (p < 0.001). For all other Manitoban children, the incidence increased from 3‧3 to 10‧7/100,000/year (p < 0.001). The prevalence of type 2 diabetes rose from 66‧4 to 124‧2/100,000/year between 2009 -10 and 2017-18 (<0.001). The prevalence in First Nation children rose from 282‧8 to 517‧9/100,000/year (p < 0.001) and in all other Manitoban children from 18‧4 to 35.0/100,000/year (p < 0.001). CONCLUSIONS: The incidence and prevalence of type 2 diabetes is increasing in Manitoban children. While the greatest increase is seen in all other Manitoban children, type 2 diabetes disproportionally affects First Nation children. Understanding the prevalence and incidence of type 2 diabetes in children is necessary for resource allocation and to inform program planning, aimed at both prevention and management.

RESUMO

Legg Calve Perthes disease is a pediatric hip condition that leads to early hip degeneration. The efficacy of operative and nonoperative treatment is not well defined in the literature. Using the rate of total hip arthroplasty as a surrogate measure for symptomatic hip degeneration, the rate of total hip arthroplasty was compared in Legg Calve Perthes disease patients with and without previous surgical intervention in the province of Manitoba, Canada. A retrospective review was conducted using de-identified, individual-level administrative records of health services for the entire population of Manitoba. Codes for Legg Calve Perthes disease, femoral osteotomies, pelvic osteotomies, adductor tenotomies, and total hip arthroplasty were searched from 1984 to 2018. The rate of total hip arthroplasty in patients with Legg Calve Perthes disease was determined for two groups: (1) patients with earlier surgical intervention and (2) patients with no previous surgical intervention. Of the 202 patients included in the study, 180 had no prior surgery and 22 had prior surgery. The rate of total hip arthroplasty between the previous operative and nonoperative groups was found to be 32% and 40%, respectively (p = 0.458). There was no significant difference in rates of total hip arthroplasty in the operative and nonoperative groups. Further prospective studies are required to elucidate the differences in outcomes between operative and nonoperative treatment groups in patients with Legg Calve Perthes disease.

RESUMO

BACKGROUND: Obesity is a chronic and progressive disease associated with significant morbidity, mortality, and health-care costs. Bariatric surgery is the most effective intervention for sustainable weight loss and resolution of obesity-related comorbidities. Studies examining comorbidity resolution largely rely on individual self-reported outcomes and electronic record reviews. We present a population-based study looking at prescription medication utilization before and after bariatric surgery as a measure of comorbidity resolution. METHODS: All patients enrolled in the Center for Metabolic and Bariatric Surgery who underwent either gastric bypass or sleeve gastrectomy between 2013 and 2019 in Manitoba were included. Demographic information, follow up, and outpatient prescription dispensation data were obtained from the Manitoba Population Research Data Repository housed at the Manitoba Centre for Health Policy for 5 years pre- and post-surgery. RESULTS: A total of 1184 patients were included. Antidepressants and selective serotonin reuptake inhibitors were the most commonly prescribed classes, and along with thyroid medication, utilization remained stable after bariatric surgery. Proton pump inhibitors and opioid class drugs increased at 1 year after surgery then returned to baseline. Glucose and lipid-lowering medications, including statins, biguanides, sulfonylureas, and insulin, were decreased. Antihypertensives, including ACE inhibitors, calcium channel blockers, angiotensin receptors blockers, thiazides, and beta blockers, similarly decreased. CONCLUSION: This is the first Canadian study employing a provincial-wide prescription database to measure long-term comorbidity resolution after bariatric surgery. The use of administrative data eliminates potential biases and inaccuracies in follow up and self-reported outcomes. Consistent with the literature, prescriptions for the treatment of metabolic syndrome all decreased and were sustained at long-term follow up. Further studies are needed to delineate the effects of altered pharmaceutical utilization on patient quality of life and health-care expenditures.

RESUMO

OBJECTIVES: The prevalence of type 2 diabetes (T2D) is increasing and Indigenous populations are at highest risk. Canadian data are crucial for health planning. METHODS: Population-based, de-identified, linked databases were used to calculate the incidence and prevalence of T2D for registered adult First Nations Manitobans and all other adult Manitobans from 2011-2012 to 2016-2017. RESULTS: The crude prevalence of T2D increased over the 6-year study period. The crude incidence of T2D for First Nations Manitobans dropped from 11.02 to 9.74 per 1,000 person-years at risk and the crude incidence for all other Manitobans did not change; in the last 2-year period, it was 6.53 per 1,000 person-years at risk. When incidence was stratified by age, the results differed between the younger and older age groups. For First Nations individuals, the adjusted incidence of T2D for those <30 years old increased over time, with no change in those ≥30 years old. For all other Manitobans, crude incidence increased over time in the young and middle age ranges (i.e. 18 to 29 years and 35 to 44 years, respectively). Both age- and sex-adjusted relative prevalence (adjusted rate ratio [aRR], 3.47; 95% confidence interval [CI], 2.56 to 4.70) and incidence (aRR, 1.97; 95% CI, 1.51 to 2.56) were higher for First Nations Manitobans. CONCLUSIONS: The prevalence of T2D continues to increase and disproportionately affects First Nations populations. Furthermore, the incidence is increasing in the younger age groups. Prevention and screening programs must include younger age groups and partner with First Nations communities.

RESUMO

OBJECTIVES: Studies on mortality differentials between international immigrants and non-immigrants produced mixed results. The mortality of interprovincial migrants has been less studied. Our objectives were to compare mortality risk between international immigrants, interprovincial migrants, and long-term residents of the province of Manitoba, Canada, and identify factors associated with mortality among migrants. METHODS: We conducted a retrospective matched-cohort study to examine all-cause and premature mortality of 355,194 international immigrants, interprovincial migrants, and long-term Manitoba residents (118,398 in each group) between January 1985 and March 2019 using linked administrative databases. Poisson regression was used to estimate adjusted incidence rate ratios (aIRR) with 95% confidence intervals (CI). RESULTS: The all-cause mortality risk of international immigrants (2.3 per 1000 person-years) and interprovincial migrants (4.4 per 1000) was lower than that of long-term Manitobans (5.6 per 1000) (aIRR: 0.43; 95% CI: 0.42, 0.45 and aIRR: 0.81; 95% CI: 0.80, 0.84, respectively). Compared with interprovincial migrants, international immigrants showed lower death risk (aIRR: 0.50; 95% CI: 0.47, 0.52). Similar trends were observed for premature mortality. Among international immigrants, higher mortality risk was observed for refugees, those from North America and Oceania, and those of low educational attainment. Among internal migrants, those from Eastern Canada had lower mortality risk than those migrating from Ontario and Western Canada. CONCLUSION: Migrants had a mortality advantage over non-migrants, being stronger for international immigrants than for interprovincial migrants. Among the two migrant groups, there was heterogeneity in the mortality risk according to migrants' characteristics.


RéSUMé: OBJECTIFS: Les études sur les écarts dans la mortalité entre les immigrants internationaux et les non-immigrants produisent des résultats mitigés. La mortalité des migrants interprovinciaux est moins étudiée. Nous avons cherché à comparer le risque de mortalité des immigrants internationaux, des migrants interprovinciaux et des résidents à long terme de la province du Manitoba, au Canada, et à cerner les facteurs associés à la mortalité chez les migrants. MéTHODE: Nous avons mené une étude de cohorte assortie rétrospective pour examiner la mortalité toutes causes confondues et la mortalité prématurée chez 355 194 immigrants internationaux, migrants interprovinciaux et résidents à long terme du Manitoba (118 398 dans chaque groupe) entre janvier 1985 et mars 2019 à l'aide de bases de données administratives maillées. Par régression de Poisson, nous avons estimé les rapports de taux d'incidence ajustés (RTAa) avec des intervalles de confiance (IC) de 95 %. RéSULTATS: Le risque de mortalité toutes causes confondues des immigrants internationaux (2,3 pour 1 000 personnes-années) et des migrants interprovinciaux (4,4 pour 1 000) était plus faible que celui des résidents à long terme du Manitoba (5,6 pour 1 000) (RTAa : 0,43; IC de 95 % : 0,42, 0,45 et RTAa : 0,81; IC de 95 % : 0,80, 0,84, respectivement). Comparativement aux migrants interprovinciaux, les immigrants internationaux présentaient un risque de mortalité plus faible (RTAa : 0,50; IC de 95 % : 0,47, 0,52). Des tendances semblables ont été observées pour la mortalité prématurée. Chez les immigrants internationaux, un risque de mortalité plus élevé a été observé chez les réfugiés, les immigrants de l'Amérique du Nord et de l'Océanie et ceux ayant un faible niveau d'instruction. Chez les migrants intérieurs, ceux de l'Est du Canada présentaient un risque de mortalité plus faible que ceux de l'Ontario et de l'Ouest canadien. CONCLUSION: Les migrants présentaient un avantage sur le plan de la mortalité par rapport aux non-migrants; cet avantage était plus prononcé chez les immigrants internationaux que chez les migrants interprovinciaux. Dans ces deux groupes de migrants, il y avait hétérogénéité dans le risque de mortalité selon les caractéristiques des migrants.

RESUMO

BACKGROUND: First Nation people living in Canada experience a high prevalence of type 2 diabetes in pregnancy. In this study, we aimed to describe maternal and neonatal outcomes in First Nation and all other females with type 2 diabetes living in Manitoba, Canada. METHODS: This was a population-level retrospective cohort study using linked administrative data from Manitoba (2012-2017). We compared First Nation females with type 2 diabetes with all other Manitoban females with type 2 diabetes, using relative risks (RRs) and 95% confidence intervals (CIs). RESULTS: A total of 2181 females with type 2 diabetes were included, and 1218 (55.8%) were First Nation. First Nation females with type 2 diabetes were significantly more likely to experience stillbirth (RR 2.14, 95% CI 1.11-4.13) and perinatal death (RR 2.39, 95% CI 1.37-4.17) than all other Manitoban females with type 2 diabetes. Offspring of First Nation females with type 2 diabetes had a higher risk of most neonatal complications than offspring of all other Manitoban females with type 2 diabetes, including a higher risk of congenital malformations (RR 1.97, 95% CI 1.30-2.99), but First Nation people did not have a higher risk of most maternal complications. INTERPRETATION: First Nation pregnant individuals living with type 2 diabetes experienced a higher risk for adverse pregnancy outcomes than all other Manitoban females with type 2 diabetes. Additional studies are needed to identify both high-risk and protective factors for pregnancy complications in First Nation people living with type 2 diabetes in pregnancy.

RESUMO

OBJECTIVE: To describe the prevalence of mental health comorbidity in children with type 2 diabetes compared to a matched population without diabetes and children with type 1 diabetes. RESEARCH DESIGN AND METHODS: Population-based cohorts of 528 youth (7-18 years of age) with prevalent type 2 diabetes, 1519 matched children without diabetes and 778 youth with type 1 diabetes were identified from a clinical registry and linked to provincial health care records to assess the prevalence of mental health comorbidity using ICD-9CM, ICD-10CA and ATC codes. RESULTS: The majority of children with type 2 diabetes were of First Nations heritage. Compared to their matched peers, children with type 2 diabetes where more likely to have a mood or anxiety disorder before and after diagnosis [RR 2.38 (1.63, 3.48) p < 0.001 and 1.70 (1.39, 2.08) p < 0.001 respectively], to attempt/complete suicide [RR 3.18 (1.30, 7.81) p = 0.012 and 2.18 (1.32, 3.60) p = 0.0002 respectively] and be prescribed an antipsychotic [RR 2.33 (1.23, 4.39) p = 0.009 and 1.76 (1.23, 2.52) p = 0.002 respectively]. Following adjustment for age and sex, children with type 2 diabetes, compared to children with type 1 diabetes where more likely to have a mood or anxiety disorder and be prescribed an antipsychotic after diagnosis [RR 1.43 (1.07, 1.91) p = 0.015; RR 2.41 (1.44, 4.06) p = 0.0009 respectively]. CONCLUSIONS: Children with type 2 diabetes have high rates of comorbid mental illness. Programs to provide care, support, and education must address the mental health comorbidity in the context of the demographic, socioeconomic, and psycho-cultural characteristics of the population.

RESUMO

OBJECTIVE: To describe hospitalization rates and reasons for hospitalization in children with type 2 diabetes (T2D) and to compare these rates to a matched cohort without diabetes and to children with type 1 diabetes (T1D). METHODS: Population-based cohorts of 528 children (7-18 years of age) with prevalent T2D, 1519 matched control children without diabetes and 778 children with T1D were identified from a clinical registry and linked to health care records to assess hospitalizations and reasons for hospitalizations using ICD-9CM and ICD-10CA codes. RESULTS: Children with T2D are more likely than their matched controls and children with T1D to be admitted to hospital in the year prior to diagnosis {RR 2.83 (1.77, 4.53) p < 0.0001 and 8.05 (4.05, 16.00) p < 0.0001, respectively}, in the first year post diagnosis {RR 3.19 (2.08, 4.89) p < 0.0001 and 3.04 (1.86, 4.98) p < 0.0001, respectively} and in the 5 year post diagnosis period {RR 1.99 (1.56, 2.53) p < 0.0001 and 1.91 (1.48, 2.46) p < 0.0001, respectively}. Mental illness was the most common cause for hospital admission in both children with T2D and their matched controls. CONCLUSIONS: This differs from children with T1D where endocrine causes constitute the most common reason for hospital admission. This analysis provides novel data on hospitalization rates and diagnoses in the increasing population of children with T2D. This information is important to inform health care programming and health policy planning to best meet the needs of this population.

RESUMO

OBJECTIVE: Our aim in this study was to determine the best administrative data case definition for pregestational diabetes exposure. METHODS: We compared the performance of case definitions for pregestational diabetes exposure within the administrative health data housed in the Manitoba Population Health Research Repository at the Manitoba Centre for Health Policy with an identified population of women in whom the diagnosis of pregestational diabetes was known from the clinical database of the Manitoba Diabetes Education Resource for Children and Adolescents (DER-CA) (August 12, 1989 through January 28, 2015). The DER-CA database contains maternal diabetes status during pregnancy and also includes women diagnosed with type 2 diabetes in childhood whose pregnancies were thus all complicated by pregestational diabetes exposure. Linkage of mother-child dyads is possible within the Repository. Diagnosis codes from the International Classification of Diseases---ninth or tenth revision and physician tariff codes were used to identify diabetes in the biologic mothers of children with type 2 diabetes identified from the DER-CA database. The timing of the diagnosis of diabetes in the mother with respect to the gestational age of the pregnancy was determined. RESULTS: The best administrative definition of pregestational diabetes exposure was any incident code for diabetes in the mother before the pregnancy of the index child or within the first 25 weeks of pregnancy (sensitivity: 84.77%; positive predictive value: 92%). CONCLUSION: The definition cited can be used to define pregestational diabetes exposure in studies utilizing administrative data.

RESUMO

OBJECTIVE: To determine if expansion of multi-use physical activity trails in an urban centre is associated with reduced rates of cardiovascular disease (CVD). METHODS: This was a natural experiment with a difference in differences analysis using administrative health records and trail-based cycling data in Winnipeg, Canada. Prior to the intervention, each year, 314,595 (IQR: 309,044 to 319,860) persons over 30 years without CVD were in the comparison group and 37,901 residents (IQR: 37,213 to 38,488) were in the intervention group. Following the intervention, each year, 303,853 (IQR: 302,843 to 304,465) persons were in the comparison group and 35,778 (IQR: 35,551 to 36,053) in the intervention group. The natural experiment was the construction of four multi-use trails, 4-7 km in length, between 2010 and 2012. Intervention and comparison areas were based on buffers of 400 m, 800 m and 1200 m from a new multi-use trail. Bicycle counts were obtained from electromagnetic counters embedded in the trail. The primary outcome was a composite of incident CVD events: CVD-related mortality, ischemic heart disease, cerebrovascular events and congestive heart failure. The secondary outcome was a composite of incident CVD risk factors: hypertension, diabetes and dyslipidemia. RESULTS: Between 2014 and 2018, 1,681,125 cyclists were recorded on the trails, which varied ~ 2.0-fold across the four trails (2358 vs 4264 counts/week in summer months). Between 2000 and 2018, there were 82,632 CVD events and 201,058 CVD risk events. In propensity score matched Poisson regression models, the incident rate ratio (IRR) was 1.06 (95% CI: 0.90 to 1.24) for CVD events and 0.95 (95%CI: 0.88 to 1.02) for CVD risk factors for areas within 400 m of a trail, relative to comparison areas. Sensitivity analyses indicated this effect was greatest among households adjacent to the trail with highest cycling counts (IRR = 0.85; 95% CI: 0.75 to 0.96). CONCLUSIONS: The addition of multi-use trails was not associated with differences in CVD events or CVD risk factors, however the differences in CVD risk may depend on the level of trail use. TRIAL REGISTRATION: Trial registration number: NCT04057417 .

RESUMO

OBJECTIVES: Recent research has shown that cardiovascular disease (CVD) raises the risk of dementia and other forms of cognitive decline. Generally, these studies are unable to model the time of diagnosis of CVD in their analyses and treat CVD as a time-fixed variable. Our objective was to assess the risk of being diagnosed with dementia for individuals diagnosed with CVD when CVD is time-dependent. METHODS: We performed a retrospective cohort study using administrative health datasets from the Manitoba Population Research Data Repository in Canada. We constructed a longitudinal dataset to track individuals enrolled in the Manitoba Health Insurance Registry between April 1, 1997 and March 31, 2015. The study population consisted of 496,192 individuals 30 years of age or older who were not diagnosed with CVD or dementia prior to April 1, 1997. Diagnoses of CVD and dementia were based on diagnosis codes from medical claims and hospitalizations and the use of prescription medications. Hazard ratios were then computed using adjusted Cox-proportional hazards analyses. RESULTS: Among the CVD subgroups considered, atrial fibrillation, ischemic heart disease, and stroke increased the risk of developing dementia, with stroke doubling one's risk of being diagnosed with the disease (hazard ratio: 1.95; 95% confidence interval: 1.9, 2.01). Age, lower socioeconomic status, and worsening comorbidities also increased the risk of being diagnosed with dementia. CONCLUSION: A diagnosis of CVD is associated with an increased risk of a future diagnosis of dementia. Promoting good cardiovascular health may serve as an effective measure for preventing dementia.


RéSUMé: OBJECTIFS: De récentes études montrent que la maladie cardiovasculaire (MCV) accroît le risque de démence et d'autres formes de déclin cognitif. De façon générale, ces études sont incapables de modéliser la date d'un diagnostic de MCV dans leurs analyses et traitent donc les MCV comme des variables fixes dans le temps. Nous avons cherché à évaluer le risque de recevoir un diagnostic de démence chez les personnes ayant un diagnostic de MCV quand la MCV est variable dans le temps. MéTHODE: Nous avons mené une étude de cohorte rétrospective à l'aide des fichiers de données administratives sur la santé du Dépôt de données de recherche en santé des populations du Manitoba, au Canada. Nous avons construit un fichier longitudinal pour suivre les personnes inscrites au registre d'assurance-maladie du Manitoba entre le 1er avril 1997 et le 31 mars 2015. La population étudiée comptait 496 192 personnes de 30 ans et plus n'ayant pas reçu de diagnostic de MCV ou de démence avant le 1er avril 1997. Les diagnostics de MCV et de démence étaient fondés sur les codes diagnostiques dans les demandes d'indemnisation de frais médicaux et les dossiers d'hospitalisation, et sur l'utilisation de médicaments sur ordonnance. Les indices de risque ont été calculés à l'aide du modèle à risques proportionnels de Cox. RéSULTATS: Dans les sous-groupes atteints de MCV que nous avons étudiés, la fibrillation atriale, la cardiopathie ischémique et l'AVC faisaient augmenter le risque de démence; l'AVC, en particulier, doublait le risque d'être diagnostiqué avec cette maladie (indice de risque : 1,95; intervalle de confiance de 95% : 1,9, 2,01). L'âge, le faible statut socioéconomique et l'évolution défavorable des comorbidités faisaient aussi augmenter le risque de recevoir un diagnostic de démence. CONCLUSION: Un diagnostic de MCV est associé à un risque accru de diagnostic de démence plus tard. La promotion d'une bonne santé cardiovasculaire pourrait donc être un moyen efficace de prévenir la démence.

RESUMO

BACKGROUND AND AIMS: High-risk alcohol consumption is associated with compromised health. This study aimed to compare the incidence of alcohol-related cancers, diabetes, ischemic heart disease (IHD) and mortality between those with and without an indication of alcohol use disorder (AUD). DESIGN: Retrospective, population-based, matched cohort study using data from the Manitoba Population Research Data Repository. Rates were modeled using generalized linear models with either negative binomial distribution or Poisson distribution and a log offset of person-years to account for each person's time to follow-up. SETTING: Manitoba, Canada. PARTICIPANTS: Individuals aged ≥ 12 years with a first indication of AUD (index date) between 1 April 1990 and 31 March 2015 were matched to five controls based on age, sex and geographical region at index. This study included 53 410 individuals with AUD and 264 857 matched controls. MEASUREMENTS: Adjusted rate ratios (aRR) and 95% confidence intervals (CI) were determined for each outcome from 5 years prior to and 20 years after AUD detection. FINDINGS: Alcohol-related cancers (aRR = 4.85, 95% CI = 3.88-6.07 and aRR = 1.85, 95% CI = 1.35-2.53 for men and women, respectively), diabetes (aRR = 1.74, 95% CI = 1.50-2.02 and aRR = 2.43, 95% CI = 2.20-2.68) and IHD (aRR = 3.59, 95% CI = 3.31-3.90 and aRR = 2.92, 95% CI = 2.50-3.41) peaked in the 1 year prior to index for those with AUD compared with matched controls. All-cause mortality (aRR = 3.31, 95% CI = 3.09-3.55 and aRR =3.61, 95% CI = 3.21-4.04) was highest in the year of index and remained higher among cases compared with controls throughout the 20-year follow-up. CONCLUSION: People with alcohol use disorder appear to have higher rates of adverse health outcomes in the year before alcohol use disorder recognition, and death at the time of alcohol use disorder recognition, compared with matched controls.

RESUMO

OBJECTIVE: Update the evidence on use of pharmacotherapy for alcohol use disorder in a Canadian population. METHODS: Using whole-population administrative data from Manitoba, Canada, we identified all residents age 12+ who were first diagnosed with alcohol use disorder between April 1, 1996 and March 31, 2015, and compared characteristics of those who filled a prescription for naltrexone, acamprosate or disulfiram at least once during that period to those who did not fill a prescription for an alcohol use disorder medication. RESULTS: Only 1.3% of individuals with alcohol use disorder received pharmacotherapy (62.3% of prescriptions were for naltrexone, 39.4% for acamprosate, 7.5% for disulfiram). Most prescriptions came from family physicians in urban alcohol use disorder (53.6%) and psychiatrists (22.3%). Individuals were more likely to fill a prescription for alcohol use disorder medication if they lived in an urban vs rural environment (OR 2.25; 95% CI 1.83-2.77) or had a mood/anxiety disorder diagnosis vs no diagnosis (OR 2.40, 95% CI 1.98-2.90) in the five years before being diagnosed with alcohol use disorder. CONCLUSION: Despite established evidence for the effectiveness of pharmacotherapy for alcohol use disorder, these medications continue to be profoundly underutilized in Canada.

RESUMO

OBJECTIVE: Missed screening opportunities may contribute to the rising rates of sexually transmitted and blood borne infections (STBBIs) in Manitoba. This study sought to determine the proportion of women who are screened for syphilis and human immunodeficiency virus (HIV) when admitted with pelvic inflammatory disease (PID). METHODS: We performed a retrospective analysis of all inpatient admissions for PID over 3 discrete years (fiscal years 2007, 2012, 2017) at a single tertiary care centre. Data extracted from medical records included STBBI screening performed, clinical signs at presentation, and history of PID or STBBI. To improve the accuracy of our estimates, we complemented the records data with population data from Manitoba. We evaluated predictive factors influencing any or concurrent STBBI screening using bivariate analysis for significance (P < 0.05). RESULTS: One hundred and five admissions met inclusion criteria. Syphilis and HIV screening was ordered concurrently with chlamydia and gonorrhoea screening in 6 (6%) of encounters and was ordered at any point during admission for PID in 28 (27%). A history of substance abuse (odds ratio [OR] 4.94 [95% CI 1.62-15.05] for syphilis screening and OR 6.94 [95% CI 2.38-20.23] for HIV screening) and a positive gonorrhea result while admitted (OR 3.40 [95% CI 1.06-10.88] for syphilis screening) were strongly associated with receiving any screening. Reporting multiple sexual partners was also strongly associated with receiving any STBBI screening while admitted (OR 19.44 [95% CI 2.01-187.92] and OR 15.00 [95% CI 1.58-142.70] for syphilis and HIV screening, respectively). CONCLUSION: A minority of patients were screened for syphilis and HIV while admitted for PID. This study highlights a missed opportunity to screen for STBBI among sexually active women.

RESUMO

OBJECTIVE: To determine the rate of total knee replacement (TKR) after anterior cruciate ligament reconstruction (ACL-R) compared to the general population. DESIGN: Retrospective review. SETTING: All hospitals that performed TKR and ACL-R in Manitoba between 1980 and 2015. PARTICIPANT: All patients that underwent TKR and ACL-R in Manitoba between 1980 and 2015. INTERVENTION: Patient factors gathered at time of surgery included: age, sex, urban or rural residence, neighborhood income quintile, and resource utilization band (RUB). Each person was matched with up to 5 people from the general population who had never had ACL-R and had not had a TKR at the time of the case ACL-R. MAIN OUTCOME MEASURES: The rate of TKR after ACL-R. RESULTS: Overall from 1980 to 2015, 8500 ACL-R were identified within the 16 to 60 years age group with a resultant 42 497 population matches. Sex was predominantly male. The mean age of the ACL-R group at the time of TKR was 53.7 years, whereas the mean age for the matched cohort was 58.2 years, P < 0.001. Those with ACL-R were 4.85 times more likely to go on to have TKR. Apart from age, no other risk factors examined (location, year of surgery, place of residence, income quintile, and RUB) seemed to increase risk of TKR after ACL-R. CONCLUSION: Patients who underwent ACL-R were 5 times more likely to undergo TKR.

RESUMO

BACKGROUND: Alcohol is the drug most commonly used by Canadians, with multiple impacts on health and health service use. We examined patterns of short- and long-term health service use among people with a diagnosis of alcohol use disorder. METHODS: In this retrospective matched cohort study, we used population-based administrative data from the province of Manitoba, Canada, to identify individuals aged 12 years or older with a first indication of alcohol use disorder (index date) in the period 1990 to 2015. We matched cases (those with diagnosis of alcohol use disorder) to controls (those without this diagnosis), at a 1:5 ratio, on the basis of age, sex, geographic region and income quintile at the index date. The outcome measures were inpatient hospital admission, outpatient physician visits, emergency department visits and use of prescription medications. We modelled crude rates using generalized estimating equations with either a negative binomial or a Poisson distribution RESULTS: We identified 53 410 people with alcohol use disorder and 264 857 matched controls. All outcomes occurred at a higher rate among people with the disorder than among controls. For example, during the year of diagnosis, the rate ratio for hospital admission was 4.0 (95% confidence interval [CI] 3.9-4.2) for women and 4.5 (95% CI 4.4-4.7) for men. All rates of health service use peaked close to the index date, but remained significantly higher among people with alcohol use disorder than among controls for 20 years. Among people with alcohol use disorder, the most commonly filled prescriptions were for psycholeptics, whereas among controls, the most commonly filled prescriptions were for sex hormones (women) and antihypertensives (men). INTERPRETATION: Compared with controls, people with alcohol use disorder used significantly more health services from the time of diagnosis and over the next 20 years. This finding highlights the need for better detection and early intervention to reduce the need for acute and emergency care, as well as the need for improved management of alcohol use disorder over the longer term.

RESUMO

BACKGROUND: First Nations people are more likely than the general population to experience long-term adverse health outcomes after coronary angiography. Our aim was to quantify the extent of coronary artery disease among First Nations and non-First Nations patients undergoing angiography to investigate differences in coronary artery disease and related health disparities. METHODS: We conducted a retrospective matched cohort study to compare health outcomes of First Nations and non-First Nations adult patients (> 18 yr) who underwent index angiography between Apr. 1, 2008, and Mar. 31, 2012, in Manitoba, Canada. The SYNTAX Score was used to measure and compare severity of coronary artery disease between groups. Primary outcomes of all-cause and cardiovascular mortality were compared between groups using Cox proportional hazard models adjusted by SYNTAX Score results and weighted by the inverse probability of being First Nations. Secondary outcomes included all-cause and cardiovascular-related hospital admissions. RESULTS: The cohort consisted of 277 matched pairs of First Nations and non-First Nations patients undergoing angiography; the average age of patients was 56.0 (standard deviation 11.7) years. The median SYNTAX Score results and patient distributions across categories in the matched paired cohort groups were not significantly different. Although proportionally First Nations patients showed worse health outcomes, mortality risks were similar in the weighted sample, even after controlling for revascularization and SYNTAX Score results. Secondary outcomes showed that adjusted risks for hospital admission for acute myocardial infarction (adjusted hazard ratio [HR] 3.03, 95% confidence interval [CI] 1.40-6.55) and for congestive heart failure (adjusted HR 3.84, 95% CI 1.37-10.78) were significantly higher among First Nations patients in the weighted sample. INTERPRETATION: The extent of coronary artery disease among matched cohort groups of First Nations and non-First Nations patients appears similar, and controlling for baseline sociodemographic characteristics, coronary artery disease risk factors and SYNTAX Score results explained higher mortality risk and most hospital admissions among First Nations patients. Although there is a need to decrease risk factors for coronary artery disease among First Nations populations, addressing individuals' behaviour without considering root causes underlying risk factors for coronary artery disease will fail to decrease health outcome disparities among First Nations patients undergoing angiography.

RESUMO

BACKGROUND: It is unclear whether intrauterine exposure to maternal diabetes is associated with risk factors for cardiovascular disease and related end points in adulthood. We examined this potential association in a population-based birth cohort followed up to age 35 years. METHODS: We performed a cohort study of offspring born between 1979 and 2005 (n = 293 546) and followed until March 2015 in Manitoba, Canada, using registry-based administrative data. The primary exposures were intrauterine exposure to gestational diabetes and type 2 diabetes mellitus. The primary outcome was a composite measure of incident cardiovascular disease events, and the secondary outcome was a composite of risk factors for cardiovascular disease in offspring followed up to age 35 years. RESULTS: The cohort provided 3 628 576 person-years of data (mean age at latest follow-up 20.5 [standard deviation 6.4] years, 49.3% female); 2765 (0.9%) of the offspring experienced a cardiovascular disease end point, and 12 673 (4.3%) experienced a cardiovascular disease risk factor. After propensity score matching, the hazard for cardiovascular disease end points was elevated in offspring exposed to gestational diabetes (adjusted hazard ratio [HR] 1.42, 95% confidence interval [CI] 1.12-1.79) but not type 2 diabetes (adjusted HR 1.40, 95% CI 0.98-2.01). A similar association was observed for cardiovascular disease risk factors (gestational diabetes: adjusted HR 1.92, 95% CI 1.75-2.11; type 2 diabetes: adjusted HR 3.40, 95% CI 3.00-3.85). INTERPRETATION: Intrauterine exposure to maternal diabetes was associated with higher morbidity and risk related to cardiovascular disease among offspring up to 35 years of age.

RESUMO

OBJECTIVE: To investigate associations between concussion and the risk of follow-up diagnoses of attention-deficit hyperactivity disorder (ADHD), mood and anxiety disorders (MADs), dementia and Parkinson's disease. DESIGN: A retrospective population-based cohort study. SETTING: Administrative health data for the Province of Manitoba between 1990-1991 and 2014-2015. PARTICIPANTS: A total of 47 483 individuals were diagnosed with a concussion using International Classification of Diseases (ICD) codes (ICD-9-CM: 850; ICD-10-CA: S06.0). All concussed subjects were matched with healthy controls at a 3:1 ratio based on age, sex and geographical location. Associations between concussion and conditions of interest diagnosed later in life were assessed using a stratified Cox proportional hazards regression model, with adjustments for socioeconomic status and pre-existing medical conditions. RESULTS: 28 021 men (mean age ±SD, 25±18 years) and 19 462 women (30±21 years) were included in the concussion group, while 81 871 men (25±18 years) and 57 159 women (30±21 years) were included in the matched control group. Concussion was associated with adjusted hazard ratios of 1.39 (95% CI 1.32 to 1.46, p<0.001) for ADHD, 1.72 (95% CI 1.69 to 1.76; p<0.001) for MADs, 1.72 (95% CI 1.61 to 1.84; p<0.001) for dementia and 1.57 (95% CI 1.41 to 1.75; p<0.001) for Parkinson's disease. CONCLUSION: Concussion was associated with an increased risk of diagnosis for all four conditions of interest later in life.
