A comparison of trauma patients in urban and rural areas presenting to a Canadian tertiary care centre.

BACKGROUND: The aim of our work was to examine differences between trauma patients in rural and urban areas who presented to a tertiary trauma centre in the province of Saskatchewan, Canada. METHODS: We identified a historical cohort of all level 1 trauma activations presenting to Royal University Hospital (RUH) from April 1, 2020, to March 31, 2022. We divided the cohort into 2 groups (urban and rural), according to the trauma location. The primary outcome of interest was 30-day mortality. Secondary outcomes of interest were hospital length of stay, readmission to hospital within 30 days of discharge, and complication rate. RESULTS: Trauma patients in rural areas were younger (34.1 v. 37 yr; p = 0.002) and more likely to be male (80.3% v. 74.4%; p = 0.040), with higher Injury Severity Scores (12.3 v. 8.3; p < 0.0001). Trauma patients in urban areas were more likely to sustain penetrating trauma (42.5% v. 28.5%; p < 0.0001). We saw no differences in morbidity and mortality between the 2 groups, but the rural trauma group had longer median lengths of stay (5 v. 3 d; p < 0.0007). CONCLUSION: Although we identified key differences in patient demographics, injury type, and injury severity, outcomes were largely similar between the urban and rural trauma groups. This finding contradicts comparable studies within Canada and the United States, a difference that may be attributable to the lack of inclusion of prehospital mortality in the rural trauma group. The longer length of stay in trauma patients from rural areas may be attributed to disposition challenges for patients who live remotely.

HPV Self-Sampling for Cervical Cancer Screening in Under-Screened Saskatchewan Populations: A Pilot Study.

Of all cancers in female Canadians, the most rapidly increasing incidence is that of cervical cancer. The objective of this pilot study was to assess how HPV self-sampling might improve cervical cancer screening participation in both urban and rural settings in Saskatchewan, one of the most sparsely populated provinces in Canada. Study groups consisted of n = 250 participants to whom self-swabbing kits were mailed with instructions and n = 250 participants to whom kits were handed out in 6 urban and rural clinics. The inclusion criteria selected subjects aged 30-69 years who were Saskatchewan residents for at least 5 years with valid health coverage, had a cervix, and had no record of cervical cancer screening in 4 years. The returned samples were analyzed for specific HPV strains using the Roche Molecular Diagnostics Cobas 4800® System. The overall response rate was ~16%, with the response to the handout distribution being roughly double that of the mailout. While HPV positivity did not differ across the distribution groups, participants at a specific inner-city clinic reported significantly higher positivity to at least one HPV strain as compared to any other clinic and all mailouts combined. For this high-risk population, in-person handout of self-sampling kits may be the most effective means of improving screening.

The Gigii-Bapiimin Study: resilience and the impacts of COVID-19 on health and wellbeing of Indigenous people living with HIV in Manitoba and Saskatchewan.

The Gigii-Bapiimin study explored the impacts of the COVID-19 pandemic on the health and wellbeing of First Nations, Inuit, and Métis people living with HIV in Manitoba and Saskatchewan, two provinces in Canada with alarmingly high rates of HIV infections. Participants (n = 28 in Manitoba and n = 23 in Saskatchewan) were recruited using various methods, including flyers, community organizations, peers, and social media. The qualitative interviews focused on the pandemic's impact on health, access to services, and ceremonies. The data were analyzed using inductive thematic analysis. The study identified three key themes: (a) resilience and coping; (b) negative impacts on health and substance use; (c) decreased access to health services, HIV care and harm reduction. The participants shared their experiences of social isolation and the loss of community support, which had deleterious effects on their mental health and substance use. The impacts on access to HIV care were exacerbated by poverty, homelessness, and distress over inadvertent disclosure of HIV status. Participants mitigated these impacts by relying on Indigenous knowledges, ceremonies, and resilience within their communities. Service providers must address the impacts of the COVID-19 pandemic on Indigenous people living with HIV and their access to HIV services and ceremonies.

Detection of Chronic Wasting Disease Prions in Prairie Soils from Endemic Regions.

Chronic wasting disease (CWD) is a contagious prion disease that affects cervids in North America, Northern Europe, and South Korea. CWD is spread through direct and indirect horizontal transmission, with both clinical and preclinical animals shedding CWD prions in saliva, urine, and feces. CWD particles can persist in the environment for years, and soils may pose a risk for transmission to susceptible animals. Our study presents a sensitive method for detecting prions in the environmental samples of prairie soils. Soils were collected from CWD-endemic regions with high (Saskatchewan, Canada) and low (North Dakota, USA) CWD prevalence. Heat extraction with SDS-buffer, a serial protein misfolding cyclic amplification assay coupled with a real-time quaking-induced conversion assay was used to detect the presence of CWD prions in soils. In the prairie area of South Saskatchewan where the CWD prevalence rate in male mule deer is greater than 70%, 75% of the soil samples tested were positive, while in the low-prevalence prairie region of North Dakota (11% prevalence in male mule deer), none of the soils contained prion seeding activity. Soil-bound CWD prion detection has the potential to improve our understanding of the environmental spread of CWD, benefiting both surveillance and mitigation approaches.

Anticoagulant rodenticide toxicity in dogs: A retrospective study of 349 confirmed cases in Saskatchewan.

Objective: To evaluate the signalment and clinical, laboratory, treatment, and outcome features of dogs diagnosed with anticoagulant rodenticide (AR) intoxication in Saskatchewan. Animals: We studied 349 dogs. Procedure: Medical records from the Veterinary Medical Centre (Saskatoon, Saskatchewan) between 1999 and 2022 were reviewed. Cases were included if they met at least 1 of the following criteria: owner witnessed the dog ingesting an AR; AR was seen in the vomitus when emesis was induced; the dog had clinical signs of coagulopathy, with elevation of PT ± aPTT that normalized after vitamin K1 therapy, in the presence of appropriate clinical and paraclinical data and the absence of other causes of hypocoagulable state determined by the primary clinician. Results: Fifty-three percent of cases were seen between July and October. Most dogs (61%) came from an urban setting. Ninety-two percent of dogs ingested a 2nd-generation AR and the most frequent toxin was bromadiolone. Clinical signs were reported in 30% of AR intoxications and included lethargy (86%), dyspnea (55%), and evidence of external hemorrhage (44%). The most common site of hemorrhage was the pleural space, accounting for 43% of hemorrhage sites. Consumptive thrombocytopenia was reported in 24% of dogs with evidence of AR-induced hemorrhage, with moderate (platelet count < 60 K/µL) and marked (< 30 K/µL) thrombocytopenia in 7/12 and 2/12 dogs, respectively. Blood products were administered to 84% of dogs with AR-induced hemorrhage; the most common product administered was fresh frozen plasma (56% of cases). Among dogs with AR-induced hemorrhage, those that received blood products were more likely to survive to discharge (81%) compared to those that did not (19%) (P = 0.017). Eighty-six percent of dogs with AR-induced hemorrhage survived to discharge. Conclusion and clinical relevance: The pleural space was the most common site of hemorrhage. Moderate thrombocytopenia was a common finding. Eighty-six percent of dogs with AR-induced hemorrhage survived to discharge.

Toxicité des rodenticides anticoagulants chez les chiens : étude rétrospective de 349 cas confirmés en Saskatchewan. Objectif: Évaluer le signalement et les caractéristiques cliniques, de laboratoire, de traitement et de résultats des chiens diagnostiqués avec une intoxication par un rodenticide anticoagulant (AR) en Saskatchewan. Animaux: Nous avons étudié 349 chiens. Procédure: Les dossiers médicaux du Veterinary Medical Centre (Saskatoon, Saskatchewan) entre 1999 et 2022 ont été examinés. Les cas ont été inclus s'ils répondaient à au moins 1 des critères suivants : le propriétaire a vu le chien ingérer un AR; de l'AR a été observée dans les vomissures lorsque des vomissements ont été provoqués; le chien présentait des signes cliniques de coagulopathie, avec une élévation du PT ± aPTT qui s'est normalisée après un traitement par la vitamine K1, en présence de données cliniques et paracliniques appropriées et en l'absence d'autres causes d'état hypocoagulable déterminées par le clinicien initial. Résultats: Cinquante-trois pour cent des cas ont été observés entre juillet et octobre. La plupart des chiens (61 %) venaient d'un milieu urbain. Quatre-vingt-douze pour cent des chiens ont ingéré un AR de 2e génération et la toxine la plus fréquente était la bromadiolone. Des signes cliniques ont été rapportés dans 30 % des intoxications par AR et incluaient de la léthargie (86 %), de la dyspnée (55 %) et des signes d'hémorragie externe (44 %). Le site d'hémorragie le plus fréquent était l'espace pleural, représentant 43 % des sites d'hémorragie. Une thrombocytopénie de consommation a été rapportée chez 24 % des chiens présentant des signes d'hémorragie induite par l'AR, avec une thrombocytopénie modérée (nombre de plaquettes < 60 K/µL) et marquée (< 30 K/µL) chez 7 chiens sur 12 et 2 chiens sur 12, respectivement. Des produits sanguins ont été administrés à 84 % des chiens présentant une hémorragie induite par l'AR; le produit le plus fréquemment administré était le plasma frais congelé (56 % des cas). Parmi les chiens présentant une hémorragie induite par l'AR, ceux qui ont reçu des produits sanguins étaient plus susceptibles de survivre jusqu'à leur congé (81 %) que ceux qui n'en ont pas reçu (19 %) (P = 0,017). Quatre-vingt-six pour cent des chiens présentant une hémorragie induite par l'AR ont survécu jusqu'à leur sortie. Conclusion et pertinence clinique: L'espace pleural était le site d'hémorragie le plus fréquent. Une thrombocytopénie modérée était fréquente. Quatre-vingt-six pour cent des chiens présentant une hémorragie induite par l'AR ont survécu jusqu'à leur sortie.(Traduit par Dr Serge Messier).

Rural-urban differences in use of health services before and after dementia diagnosis: a retrospective cohort study.

BACKGROUND: Rural-urban differences in health service use among persons with prevalent dementia are known. However, the extent of geographic differences in health service use over a long observation period, and prior to diagnosis, have not been sufficiently examined. The purpose of this study was to examine yearly rural-urban differences in the proportion of patients using health services, and the mean number of services, in the 5-year period before and 5-year period after a first diagnosis of dementia. METHODS: This population-based retrospective cohort study used linked administrative health data from the Canadian province of Saskatchewan to investigate the use of five health services [family physician (FP), specialist physician, hospital admission, all-type prescription drug dispensations, and short-term institutional care admission] each year from April 2008 to March 2019. Persons with dementia included 2,024 adults aged 65 years and older diagnosed from 1 April 2013 to 31 March 2014 (617 rural; 1,407 urban). Matching was performed 1:1 to persons without dementia on age group, sex, rural versus urban residence, geographic region, and comorbidity. Differences between rural and urban persons within the dementia and control cohorts were separately identified using the Z-score test for proportions (p < 0.05) and independent samples t-test for means (p < 0.05). RESULTS: Rural compared to urban persons with dementia had a lower average number of FP visits during 1-year and 2-year preindex and between 2-year and 4-year postindex (p < 0.05), a lower likelihood of at least one specialist visit and a lower average number of specialist visits during each year (p < 0.05), and a lower average number of all-type prescription drug dispensations for most of the 10-year study period (p < 0.05). Rural-urban differences were not observed in admission to hospital or short-term institutional care (p > 0.05 each year). CONCLUSIONS: This study identified important geographic differences in physician services and all-type prescription drugs before and after dementia diagnosis. Health system planners and educators must determine how to use existing resources and technological advances to support care for rural persons living with dementia.

Intimidation or harassment among family medicine residents in Saskatchewan: a cross-sectional survey.

Introduction: Up to 98% of practicing family physicians, and over 75% of resident physicians in Canada experience abusive incidents. Despite the negative consequences of abusive incidents, few residents report these events to their supervisors or institution. We sought to estimate the prevalence of abusive incidents experienced or witnessed by Saskatchewan family medicine residents (FMRs) and identify their responses to these events. Methods: Anonymous survey invitations were emailed to all 110 Saskatchewan FMRs in Saskatchewan in November and December 2020. Demographic characteristics, frequency of witnessed and experienced abusive incidents, sources of incidents and residents' responses were collected. Incidents were classified as minor, major, severe, or as racial discrimination based on a previously published classification system. Results: The response rate was 34.5% (38/110). Ninety-two percent (35/38) of residents witnessed a minor incident and 91.7% (32/36) of residents experienced a minor incident. Seventy-one percent (27/38) of residents witnessed racial discrimination while 19.4% (7/36) of residents experienced racial discrimination. Patients were the most common source of abusive incidents. Twenty-nine percent of residents reported abusive incidents to their supervisors. Most residents were aware of institutional reporting policies. Conclusions: Most Saskatchewan FMRs experienced or witnessed abusive incidents, but few were reported. This study provided the opportunity to reassess policies on abusive incidents, which should consider sources of abuse, confidence in reporting, and education.

Introduction: Jusqu'à 98 % des médecins de famille en exercice et plus de 75 % des médecins résidents au Canada sont victimes d'incidents de violence. Malgré le préjudice subi, peu de résidents signalent ces incidents à leurs superviseurs ou à l'établissement. Nous avons tenté d'estimer la prévalence des incidents de violence dont ont été victimes ou témoins les résidents en médecine familiale (RMF) en Saskatchewan et de connaître leurs réactions face à ces situations. Méthodes: Des invitations à participer à un sondage anonyme ont été envoyées par courriel aux 110 RMF de la Saskatchewan en novembre et décembre 2020. Nous avons recueilli des données portant sur les caractéristiques démographiques des résidents, sur la fréquence des incidents de violence dont ils ont été témoins ou victimes, sur les sources des incidents et sur leurs réactions aux incidents. Ces derniers ont été classés comme mineurs, majeurs, graves ou comme actes de discrimination raciale sur la base d'un système de classification existant. Résultats: Le taux de réponse a été de 34,5 % (38/110). Quatre-vingt-douze pour cent (35/38) des résidents ont été témoins d'un incident mineur et 91,7 % (32/36) en ont vécu un eux-mêmes Soixante et onze pour cent (27/38) des résidents ont été témoins de discrimination raciale, tandis que 19,4 % (7/36) en ont été victimes. Le plus souvent, les auteurs de comportements violents étaient des patients. Vingt-neuf pour cent des résidents ont signalé l'incident à leur superviseur. La plupart des résidents connaissaient la politique de signalement de la violence de l'établissement. Conclusions: La plupart des RMF de la Saskatchewan ont vécu des incidents violents ou en ont été témoins, mais peu d'entre eux les ont signalés. Cette étude ouvre la voie à une réévaluation des politiques en matière de prévention de la violence, qui devraient tenir compte des sources de la violence et de la confiance des victimes envers le processus de signalement, et prévoir de la formation.

Exploring the Implications of COVID-19 on Food Security and Coping Strategies among Urban Indigenous Peoples in Saskatchewan, Canada.

The COVID-19 pandemic has notably impacted food security, especially among urban Indigenous communities. This study aimed to examine the impact of the pandemic and related lockdown measures on the food security of urban Indigenous peoples in Saskatchewan, Canada. In partnership with Indigenous co-researchers, we designed an online survey disseminated via SurveyMonkey® (San Mateo, CA, USA) from August 2021 to August 2022. This survey detailed background information, the Household Food Security Survey Module (HFSSM), state of food access, and traditional food consumption habits. Of the 130 Indigenous respondents, 75.8% were female, 21.9% male, and 2.3% non-binary, with an average age of 36.2 years. A significant 68.4% experienced food insecurity during the pandemic's first four months. Increased food prices (47.1%) and reduced market availability (41.4%) were the dominant causes. Additionally, 41.8% highlighted challenges in accessing traditional foods. Relying on community resources and government food distribution programs (40.7%) was the most reported coping strategy for those experiencing food insecurity. Notably, 43.6% reported receiving no government financial support during the crisis. This study emphasizes the severe food insecurity among urban Indigenous communities in Saskatchewan during the pandemic. The findings highlight the immediate need for interventions and policies that ensure access to culturally relevant food, especially for future crises.

Oxytetracycline-resistant Paenibacillus larvae identified in commercial beekeeping operations in Saskatchewan using pooled honey sampling.

American foulbrood (AFB) is an infectious disease of honey bee brood caused by the endospore-forming bacterium Paenibacillus larvae. P. larvae spores are resilient in the environment, thus colonies with clinical signs of AFB are often destroyed by burning to eradicate the causative agent. To prevent outbreaks of AFB, oxytetracycline metaphylaxis is widely used in North America, resulting in sustained selective pressure for oxytetracycline resistance in P. larvae. To determine if antimicrobial resistance (AMR) is present among P. larvae isolates from commercial beekeeping operations in Saskatchewan, Canada, we performed antimicrobial susceptibility testing of 718 P. larvae samples cultured from pooled, extracted honey collected from 52 beekeepers over a 2-y period, 2019 and 2020. We found that 65 of 718 (9%) P. larvae samples collected from 8 beekeepers were resistant to oxytetracycline with minimum inhibitory concentration (MIC) values of 64-256 µg/mL. Eight of 718 (1%) samples from 4 beekeepers had intermediate resistance to oxytetracycline (MIC: 4-8 µg/mL). Susceptibility testing for tylosin and lincomycin indicated that P. larvae in Saskatchewan continue to be susceptible to these antimicrobials (tylosin MIC: <1 µg/mL, lincomycin MIC: ≤2 µg/mL). Most oxytetracycline-resistant P. larvae samples were identified in northeastern Saskatchewan. Whole-genome sequence analysis identified the P. larvae-specific plasmid pMA67 with tetracycline-resistance gene tet(L) in 9 of 11 oxytetracycline-resistant P. larvae isolates sequenced. Our results highlight the advantage of using pooled, extracted honey as a surveillance tool for monitoring AMR in P. larvae.

Prevalence and factors associated with suicidal ideation, cannabis, and alcohol use during the COVID-19 pandemic in Saskatchewan: findings from a joint-effect modeling.

BACKGROUND: Generally, pandemics such as COVID-19 take an enormous toll on people's lives. As the pandemic now turns to an endemic state, growing attention has been paid to the multiple adverse mental health and behavioral issues, such as suicidal ideation and substance use. However, the interplay of suicidality and substance misuse during the pandemic has been limited. We aimed to investigate the prevalence of co-occurrence of suicide ideation, alcohol and cannabis misuse, and the factors that are associated with these co-occurrences in the province of Saskatchewan during the COVID-19 pandemic. METHODS: We performed a multivariable trivariate probit regression on a sample of 666 Saskatchewan adolescents and adults (16 years or older), drawn from the cycle 10 data collection (March 2022) of the Mental Health Commission of Canada, and Canadian Centre on Substance Use and Addiction (MHCC-CCSA) dataset. RESULTS: The prevalence of suicidal ideation was higher among respondents who reported both problematic cannabis and alcohol use (25.8%) than single users of alcohol (23.2%) and cannabis (18.7%). Younger respondents (16-34 years) and those who reported recent changes in other substance use were independent factors that were associated with the common experience of suicide ideation, problematic cannabis, and alcohol use. Having a diagnosis of mental health disorders either before or during the pandemic, and the perceived inability to bounce back after the pandemic (low resilience) are strong correlates of suicidal ideation. Those who lived alone, between 35 and 55 years of age were more likely to report problematic alcohol use. Those who reported changes in alternative activities, who reported pandemic stress, and declared a LGBTQIA2S + identity had higher probability of problematic cannabis use. CONCLUSIONS: As the pandemic persists, improving access to suicide and substance use interventions for the vulnerable groups identified in this study may be impactful.

Physical Activity and Social Interaction among Rural Older Adults in Saskatchewan during COVID-19.

Physical activity and social interaction among rural older adults are important, particularly during the COVID-19 pandemic when restrictions on physical gatherings were placed. The purpose of this qualitative study was to gain a deeper understanding of rural older adults' experience with physical activity and social interaction during the COVID-19 pandemic. An interpretative phenomenological approach was used to explore the experience of 10 older adults, 67-82 years of age, from rural communities throughout Saskatchewan. Findings revealed that many rural older adults acknowledged the health benefits of physical and social activities and experienced loneliness when COVID-19 restrictions were placed, even when living with a partner. For some, the restrictions placed on physical and social activity provided a welcome break from daily responsibilities. Rural communities, often at a disadvantage, were also perceived by participants as being protected against COVID-19. The resilience demonstrated among rural participants to persevere and adapt to their changing environment during the pandemic was evident in the findings.

The Contribution of Gestational Diabetes to Diabetes Risk Among First Nations and Non-First Nations Women in Saskatchewan: Results From the DIP: ORRIIGENSS Project.

OBJECTIVES: Our aim in this study was to determine the risk for diabetes mellitus (DM) among Saskatchewan First Nations (FN) and non-FN women with prior gestational DM (GDM). METHODS: Using Ministry of Health administrative databases, we conducted a retrospective cohort study of DM risk by GDM occurrence among FN and non-FN women giving birth from 1980 to 2009 and followed to March 31, 2013. We determined frequencies and odds ratios (ORs) of DM in women with/without prior GDM after stratifying by FN status, while adjusting for other DM determinants. Survival curves of women until DM diagnosis were obtained by prior GDM occurrence and stratified by ethnicity and total parity. RESULTS: De-identified data were obtained for 202,588 women. Of those who developed DM, 2,074 of 10,114 (20.5%) had previously experienced GDM (811 of 3,128 [25.9%]) FN and 1,263 of 6,986 [18.1%] non-FN). Cumulative survival of women with prior GDM until DM was higher for FN than for non-FN women (82% vs 46%), but prior GDM was a stronger predictor of DM within the non-FN cohort (prior GDM vs no GDM: OR, 9.64 for non-FN; OR, 7.05 for FN). Finally, higher total parity interacted with prior GDM to increase DM risk in both groups. With prior GDM and parity ≥3, 93% of FN and 57% of non-FN women subsequently developed DM. CONCLUSIONS: GDM is a leading determinant of T2DM among FN and non-FN women, amplified by higher parity. This contributes to earlier onset diabetes, affecting subsequent pregnancies and increasing risk for chronic diabetic complications. It may also factor into higher type 2 DM rates observed in FN women compared with men.

Doctors' Professional and Personal Reflections: A Qualitative Exploration of Physicians' Views and Coping during the COVID-19 Pandemic.

Numerous studies have examined the risks for anxiety and depression experienced by physicians during the COVID-19 pandemic. Still, qualitative studies investigating physicians' views, and their discovered strengths, are lacking. Our research fills this gap by exploring professional and personal reflections developed by physicians from various specialties during the pandemic. Semi-structured interviews were conducted with physicians practicing in the province of Saskatchewan, Canada, during November 2020-July 2021. Thematic analysis identified core themes and subthemes. Seventeen physicians, including nine males and eight females, from eleven specialties completed the interviews. The pandemic brought to the forefront life's temporality and a new appreciation for life, work, and each other. Most physicians found strength in values, such as gratitude, solidarity, and faith in human potential, to anchor them professionally and personally. A new need for personal fulfilment and hybrid care emerged. Negative feelings of anger, fear, uncertainty, and frustration were due to overwhelming pressures, while feelings of injustice and betrayal were caused by human or system failures. The physicians' appreciation for life and family and their faith in humanity and science were the primary coping strategies used to build adaptation and overcome negative emotions. These reflections are summarized, and implications for prevention and resilience are discussed.

Farm Exposures and Allergic Disease Among Children Living in a Rural Setting.

OBJECTIVES: The purpose of this study was to examine the association between farm exposures and asthma and allergic disease in children while also highlighting the experiences of non-farm rural children. METHODS: This was a cross-sectional analysis of data collected from across the province of Saskatchewan, Canada in 2014. Surveys were completed by parents of 2275 rural dwelling children (farm and non-farm) aged 0 to 17 years within 46 rural schools. Questionnaires were distributed through schools for parents to complete. RESULTS: Asthma prevalence was 7.6%, of which 29.5% of cases were allergic. After adjustment for potential confounders, home location (farm vs non-farm) and other farm exposures were not associated with asthma and asthma phenotypes. Those who completed farm safety education were more likely to have asthma (11.7% vs. 6.7%; p = .001) compared to children without asthma. In sub-analyses among 6-12-year-old children, boys were more likely to have asthma (non-allergic) and use short-acting beta-agonists compared to girls. Doing farm work in the summer was associated with an increased risk of asthma [adjusted OR (aOR) = 1.71 (1.02-2.88); p = .041]. Doing routine chores with large animals was associated with an increased risk of asthma [aOR = 1.83 (1.07-3.15); p = .027] and allergic asthma [aOR = 2.37 (95%CI = 1.04-5.40); p = .04]. CONCLUSION: The present study showed that the prevalence of asthma and asthma phenotypes were similar between farm and non-farm rural children. There did not appear to be differential involvement in farming activities between those with and without asthma although those with asthma had more training suggesting possible attempts to mitigate harm from farm exposures.

A wastewater-based risk index for SARS-CoV-2 infections among three cities on the Canadian Prairie.

Wastewater surveillance (WWS) is useful to better understand the spreading of coronavirus disease 2019 (COVID-19) in communities, which can help design and implement suitable mitigation measures. The main objective of this study was to develop the Wastewater Viral Load Risk Index (WWVLRI) for three Saskatchewan cities to offer a simple metric to interpret WWS. The index was developed by considering relationships between reproduction number, clinical data, daily per capita concentrations of virus particles in wastewater, and weekly viral load change rate. Trends of daily per capita concentrations of SARS-CoV-2 in wastewater for Saskatoon, Prince Albert, and North Battleford were similar during the pandemic, suggesting that per capita viral load can be useful to quantitatively compare wastewater signals among cities and develop an effective and comprehensible WWVLRI. The effective reproduction number (Rt) and the daily per capita efficiency adjusted viral load thresholds of 85 × 106 and 200 × 106 N2 gene counts (gc)/population day (pd) were determined. These values with rates of change were used to categorize the potential for COVID-19 outbreaks and subsequent declines. The weekly average was considered 'low risk' when the per capita viral load was 85 × 106 N2 gc/pd. A 'medium risk' occurs when the per capita copies were between 85 × 106 and 200 × 106 N2 gc/pd. with a rate of change <100 %. The start of an outbreak is indicated by a 'medium-high' risk classification when the week-over-week rate of change was >100 %, and the absolute magnitude of concentrations of viral particles was >85 × 106 N2 gc/pd. Lastly, a 'high risk' occurs when the viral load exceeds 200 × 106 N2 gc/pd. This methodology provides a valuable resource for decision-makers and health authorities, specifically given the limitation of COVID-19 surveillance based on clinical data.

Public support for safer supply programs: analysis of a cross-sectional survey of Canadians in two provinces.

OBJECTIVES: Canada's ongoing drug poisoning crisis has contributed to unprecedented rates of morbidity and mortality. Health Canada has funded safer supply pilot programs to help connect people who use drugs to pharmaceutical grade medications that reduce their reliance on a toxic drug supply. However, most provinces, including Alberta and Saskatchewan, have not endorsed these initiatives. We explored public support for safer supply programs in these two Canadian provinces and identified predictors of support for this policy option. METHODS: Cross-sectional data were examined from an online panel survey that included measures assessing views on policy responses to substance use and addiction. A total of 1602 adults were recruited during March 2021. We used descriptive statistics to characterize support for safer supply programs in Alberta and Saskatchewan and multinominal logistic regression analysis to examine predictors of public support for safer supply. RESULTS: The majority of respondents (AB: 63.5% and SK: 56.3%) supported safer supply programs that replace illegal street drugs with pharmaceutical alternatives for those unable to stop using. Predicted probabilities show a greater probability of support for safer supply among those with higher education and those leaning left on the political spectrum. CONCLUSION: A majority of Canadians from Alberta and Saskatchewan supported provincial government efforts to expand safer supply, suggesting a lack of public support is not the main barrier to implementation. Efforts at mobilizing this public opinion are needed to scale up and facilitate evaluation of this drug poisoning response.

RéSUMé: OBJECTIFS: La crise de l'empoisonnement aux drogues qui perdure au Canada contribue à des taux de morbidité et de mortalité sans précédent. Santé Canada finance des programmes pilotes pour aider les personnes qui font usage de drogue à obtenir des médicaments de qualité pharmaceutique de sources plus sûres qui réduisent leur dépendance envers les stocks de médicaments toxiques. Cependant, la plupart des provinces, dont l'Alberta et la Saskatchewan, n'ont pas avalisé ces initiatives. Nous avons exploré l'appui du public aux programmes d'approvisionnement plus sécuritaire dans ces deux provinces canadiennes et cerné les variables prédictives de l'appui à cette option stratégique. MéTHODE: Nous avons étudié les données transversales d'une enquête par panel menée en ligne qui incluait des mesures d'évaluation des opinions sur les réponses politiques à l'usage de substances et aux toxicomanies. En tout, 1 602 adultes ont été recrutés en mars 2021. Nous avons fait appel à des statistiques descriptives pour caractériser l'appui aux programmes d'approvisionnement plus sécuritaire en Alberta et en Saskatchewan et à une analyse de régression logistique multinomiale pour examiner les variables prédictives de l'appui du public à l'approvisionnement plus sécuritaire. RéSULTATS: La majorité des répondants (Alberta : 63,5 %; Saskatchewan : 56,3 %) étaient en faveur des programmes d'approvisionnement plus sécuritaire qui remplacent les drogues de rue illicites par des médicaments de qualité pharmaceutiques pour les personnes incapables de cesser de consommer. Les probabilités prédites montrent une probabilité accrue d'appui à l'approvisionnement plus sécuritaire chez les personnes ayant fait des études supérieures et les personnes à gauche de l'échiquier politique. CONCLUSION: Une majorité de Canadiennes et de Canadiens de l'Alberta et de la Saskatchewan appuyaient les efforts des gouvernements provinciaux pour élargir l'approvisionnement plus sécuritaire, ce qui indique qu'un manque d'appui du public n'est pas le principal obstacle à la mise en œuvre de l'initiative. Des efforts de mobilisation de l'opinion sont nécessaires pour intensifier cette intervention de lutte contre l'empoisonnement aux drogues et pour en faciliter l'évaluation.

Comorbidity and risk factors of subsequent lower extremity amputation in patients diagnosed with diabetes in Saskatchewan, Canada.

OBJECTIVE: Subsequent limb amputation (SLA) may be necessary due to disease progression, infection, or to aid prosthesis fit. SLA in Saskatchewan has increased 3.2% from 2006 to 2019 with minor SLA increasing 9.6% during that period. Diabetes affects a large proportion of patients who require SLA; however, the impact of additional comorbidities is not clear. METHODS: First-episode subsequent lower extremity limb amputation (SLEA) cases with the presence/absence of diabetes, other comorbidities, and demographic characteristics from 2006-2019 were retrieved from Saskatchewan's Discharge Abstract Database. Logistic regression was performed to examine the magnitude of the odds of SLEA. RESULTS: Among the 956 first-episode SLEA patients investigated, 78.8% were diagnosed with diabetes. Of these, 76.1% were male and 83.0% were aged 50 + years. Three comorbidities: renal failure (AOR = 1.9, 95% Cl 1.1 - 3.0), hypertension (AOR = 3.0, 95% Cl 2.0 - 4.5), and congestive heart failure (AOR = 2.0, 95% CI 1.2 - 3.2), conferred the highest odds of SLEA. The odds of SLEA is greatest for those aged 50-69 years, males, Registered Indians, and associated with a prolonged hospital stay. DISCUSSION: These data are important as they may help medical providers identify patients at the highest risk of SLEA and target interventions to optimize outcomes.

Trends in Work-Related Fatal Farm Injuries, Saskatchewan, Canada: 2005-2019.

OBJECTIVES: This study was conducted to estimate farm fatality rates and to describe patterns of fatal agricultural injuries on Saskatchewan farms from 2005 to 2019. METHODS: Data on work-related farm fatalities was collected from January 2005 to December 2019 in the Province of Saskatchewan as a part of the injury and mortality surveillance for the Canadian Agricultural Injury Reporting (CAIR) program. Data were abstracted from records made available by the Provincial Coroner's Office. RESULTS: There were 166 farm work-related fatalities recorded between 2005 and 2019 in Saskatchewan. The majority (93.4%) of work-related fatalities were in males. The overall work-related fatality rate was 10.5 (95% CI: 8.9-12.1) per 100,000 farm population. The overall age-adjusted work-related fatality rate was 18.1 (95% CI: 15.2-20.9) per 100,000 farm population among males and 1.4 (95% CI: 0.6-2.3) per 100,000 farm population among females. Age-adjusted rate decreased from 91.2 (95% CI: 69.4-117.66) per 100,000 farm population in 2005-2009 to 89.7 (95% CI: 64.9-120.2) per 100,000 farm population in 2015-2019 in males. Trend analysis of the work-related fatality rate in all cases showed a non-significant average annual decline of 2.6% (p = 0.156). Rollover injuries contributed to a high proportion of fatalities in children (30.0%) and the elderly population (14.9%). The most common causative agent was a tractor, and the most common location of injury was the farmyard or field. CONCLUSION: The burden of mortality in this industry is still substantial. There was a non-significant decreasing trend in the injury rate over the 15-year period. Elderly farmers continue to be at high risk for fatality, while the rates for children have declined. Application of prevention approaches could reduce the risk of fatal injury, and in particular the high proportion of rollover injuries in children and the elderly population.

The Use of General Anesthesia for Pediatric Dentistry in Saskatchewan: A Retrospective Study.

INTRODUCTION: The rate of general anesthesia (GA) use for pediatric dental treatment in Saskatchewan is among the highest in Canada. Although the prevalence of and risk factors for early childhood caries (ECC) has been reviewed nationally, few studies have focused on Saskatchewan. The objective of this study was to determine the prevalence of and predictive factors for dental treatment under GA in Saskatchewan. METHODS: This retrospective review focused on pediatric patients who required dental treatment under GA in Saskatchewan between 2015 and 2018. Demographic, dental diagnostic and treatment data and number of previous exposures to GA were collected and analyzed. RESULTS: We reviewed 570 patient records. Dental treatment needs among the sample were complex; children had 10.85 ± 3.56 (mean ± standard deviation) teeth treated, for an average cost of $3231.72 ± $898.95 per child. Children who lived in less accessible or remote locations had a significantly higher caries experience, number of teeth treated and cost of treatment. In addition, children who lived in such locations were more likely to have had previous dental treatment under GA (odds ratio [OR] 1.29, 95% CI 1.029-1.645) compared with those who lived in easily accessible/accessible areas (OR 0.81, 95% CI 0.700-0.953). CONCLUSION: Our findings confirm previous research that children who require dental treatment under GA have extensive caries and treatment needs. Our results suggest that children who live in less accessible and more remote areas of the province have a higher burden of disease and are more likely to require repeated GA exposures for dental treatment.

Health service use before and after dementia diagnosis: a retrospective matched case-control study.

OBJECTIVES: This study investigated patterns in health service usage among older adults with dementia and matched controls over a 10-year span from 5 years before until 5 years after diagnosis. DESIGN: Population-based retrospective matched case-control study. SETTING: Administrative health data of individuals in Saskatchewan, Canada from 1 April 2008 to 31 March 2019. PARTICIPANTS: The study included 2024 adults aged 65 years and older living in the community at the time of dementia diagnosis from 1 April 2013 to 31 March 2014, matched 1:1 to individuals without a dementia diagnosis on age group, sex, rural versus urban residence, geographical region and comorbidity. OUTCOME MEASURES: For each 5-year period before and after diagnosis, we examined usage of health services each year including family physician (FP) visits, specialist visits, hospital admissions, all-type prescription drug dispensations and short-term care admissions. We used negative binomial regression to estimate the effect of dementia on yearly average health service utilisation adjusting for sex, age group, rural versus urban residence, geographical region, 1 year prior health service use and comorbidity. RESULTS: Adjusted findings demonstrated that 5 years before diagnosis, usage of all health services except hospitalisation was lower among persons with dementia than persons without dementia (all p<0.001). After this point, differences in higher health service usage among persons with dementia compared to without dementia were greatest in the year before and year after diagnosis. In the year before diagnosis, specialist visits were 59.7% higher (p<0.001) and hospitalisations 90.5% higher (p<0.001). In the year after diagnosis, FP visits were 70.0% higher (p<0.001) and all-type drug prescriptions 29.1% higher (p<0.001). CONCLUSIONS: Findings suggest the year before and year after diagnosis offer multiple opportunities to implement quality supports. FPs are integral to dementia care and require effective resources to properly serve this population.
