Association between insomnia and four domains of health based on an Indigenous Medicine Wheel: Findings from two Saskatchewan First Nation communities.

OBJECTIVES: Research has shown that insomnia and chronic diseases can simultaneously impact overall health, including physical, mental, emotional, and spiritual health. This study aims to find the association between insomnia and the four domains of health based on an Indigenous Medicine Wheel and to find the role of multimorbidity as a mediator between this relation among First Nations people. METHODS: We used data (n = 588) from the First Nations Sleep Health Project, a collaboration between two Cree First Nations communities in Saskatchewan and a research team at the University of Saskatchewan. Insomnia was measured by the Insomnia Severity Index (ISI). A multivariable logistic regression model was fitted, and the strength of significant predictors was presented as odds ratio (OR) and 95% confidence interval (CI). Using generalized structural equation modelling, we assessed the mediating effect of multimorbidity after adjusting confounders. RESULTS: Most participants (~ 70%) reported good or better health in the four domains. After adjusting for potential risk factors, we found that the probability of having poor or fair health in all four domains (physical, mental, emotional, and spiritual) was higher among people with severe to moderate insomnia (OR = 3.06 (1.76-5.30), 2.77 (1.54-4.99), 3.19 (1.85-5.52), and 1.57 (0.88-2.80), respectively). Additionally, the total effect of ISI on physical, mental, emotional, and spiritual health was 51.34%, 61.72%, 44.81%, and 57.27%, respectively, mediated by multimorbidity. CONCLUSION: The impact of insomnia on four domains of health and the mediation effect of multimorbidity on this path are unique findings. Early diagnosis and treatment of these conditions might improve overall health.

RéSUMé: OBJECTIFS: Des études ont montré que l'insomnie et les maladies chroniques peuvent avoir des effets simultanés sur la santé globale, c'est-à-dire la santé physique, mentale, émotionnelle et spirituelle. Nous avons donc cherché à découvrir : l'association entre l'insomnie et les quatre domaines de santé figurant sur une roue médicinale autochtone; et l'effet médiateur de la multimorbidité sur cette relation chez les personnes des Premières Nations. MéTHODE: Nous avons utilisé les données (n = 588) du First Nations Sleep Health Project, un projet mené en collaboration par deux communautés cries des Premières nations de la Saskatchewan et par une équipe de recherche de l'Université de la Saskatchewan. Nous avons mesuré l'insomnie à l'aide de l'Index de sévérité de l'insomnie (ISI). Nous avons ajusté un modèle de régression logistique multivariée et présenté la force des variables prédictives significatives sous la forme de rapports de cotes (RC) et d'intervalles de confiance (IC) de 95%. En utilisant la modélisation par équation structurelle généralisée, nous avons évalué l'effet médiateur de la multimorbidité après ajustement des facteurs confusionnels. RéSULTATS: La plupart des participants (~ 70 %) ont déclaré une santé bonne ou mieux que bonne dans les quatre domaines. Après ajustement en fonction des facteurs de risque potentiels, nous avons constaté que la probabilité d'avoir une santé mauvaise ou passable dans les quatre domaines (physique, mental, émotionnel et spirituel) était plus élevée chez les personnes souffrant d'insomnie sévère à modérée (RC = 3,06 [1,76­5,30], 2,77 [1,54­4,99], 3,19 [1,85­5,52] et 1,57 [0,88­2,80], respectivement). Par ailleurs, l'effet total de l'ISI sur la santé physique, mentale, émotionnelle et spirituelle était de 51,34 %, 61,72 %, 44,81 % et 57,27 %, respectivement, avec l'effet médiateur de la multimorbidité. CONCLUSION: L'effet de l'insomnie sur quatre domaines de santé et l'effet médiateur de la multimorbidité à cet égard représentent des constats singuliers. Le diagnostic précoce et le traitement de ces affections pourraient améliorer la santé globale.

Sleep Efficiency and Sleep Onset Latency in One Saskatchewan First Nation.

BACKGROUND: Sleep efficiency and sleep onset latency are two measures that can be used to assess sleep quality. Factors that are related to sleep quality include age, sex, sociodemographic factors, and physical and mental health status. This study examines factors related to sleep efficiency and sleep onset latency in one First Nation in Saskatchewan, Canada. METHODS: A baseline survey of the First Nations Sleep Health project was completed between 2018 and 2019 in collaboration with two Cree First Nations. One-night actigraphy evaluations were completed within one of the two First Nations. Objective actigraphy evaluations included sleep efficiency and sleep onset latency. A total of 167 individuals participated, and of these, 156 observations were available for analysis. Statistical analysis was conducted using logistic and linear regression models. RESULTS: More females (61%) than males participated in the actigraphy study, with the mean age being higher for females (39.6 years) than males (35.0 years). The mean sleep efficiency was 83.38%, and the mean sleep onset latency was 20.74 (SD = 27.25) minutes. Age, chronic pain, ever having high blood pressure, and smoking inside the house were associated with an increased risk of poor sleep efficiency in the multiple logistic regression model. Age, chronic pain, ever having anxiety, heart-related illness, and smoking inside the house were associated with longer sleep onset latency in the multiple linear regression model. CONCLUSIONS: Sleep efficiency and sleep onset latency were associated with physical and environmental factors in this First Nation.

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.

STOP-Bang Score and Prediction of Severity of Obstructive Sleep Apnea in a First Nation Community in Saskatchewan, Canada.

The STOP-Bang questionnaire is an easy-to-administer scoring model to screen and identify patients at high risk of obstructive sleep apnea (OSA). However, its diagnostic utility has never been tested with First Nation peoples. The objective was to determine the predictive parameters and the utility of the STOP-Bang questionnaire as an OSA screening tool in a First Nation community in Saskatchewan. The baseline survey of the First Nations Sleep Health Project (FNSHP) was completed between 2018 and 2019. Of the available 233 sleep apnea tests, 215 participants completed the STOP-Bang score questionnaire. A proportional odds ordinal logistic regression analysis was conducted using the total score of the STOP-Bang as the independent variable with equal weight given to each response. Predicted probabilities for each score at cut-off points of the Apnea Hypopnea Index (AHI) were calculated and plotted. To assess the performance of the STOP-Bang questionnaire, sensitivity, specificity, positive predictive values (PPVs), negative predictive values (NPVs), and area under the curve (AUC) were calculated. These data suggest that a STOP-Bang score ≥ 5 will allow healthcare professionals to identify individuals with an increased probability of moderate-to-severe OSA, with high specificity (93.7%) and NPV (91.8%). For the STOP-Bang score cut-off ≥ 3, the sensitivity was 53.1% for all OSA and 72.0% for moderate-to-severe OSA. For the STOP-Bang score cut-off ≥ 3, the specificity was 68.4% for all OSA and 62.6% for moderate-to-severe OSA. The STOP-Bang score was modestly superior to the symptom of loud snoring, or loud snoring plus obesity in this population. Analysis by sex suggested that a STOP-Bang score ≥ 5 was able to identify individuals with increased probability of moderate-to-severe OSA, for males with acceptable diagnostic test accuracy for detecting participants with OSA, but there was no diagnostic test accuracy for females.

Obesity, Sex, Snoring and Severity of OSA in a First Nation Community in Saskatchewan, Canada.

Sleep disorders have been related to body weight, social conditions, and a number of comorbidities. These include high blood pressure and type 2 diabetes, both of which are prevalent in the First Nations communities. We explored relationships between obstructive sleep apnea (OSA) and risk factors including social, environmental, and individual circumstances. An interviewer-administered survey was conducted with adult participants in 2018−2019 in a First Nations community in Saskatchewan, Canada. The survey collected information on demographic variables, individual and contextual determinants of sleep health, and objective clinical measurements. The presence of OSA was defined as an apnea−hypopnea index (AHI) ≥5. Multiple ordinal logistic regression analysis was conducted to examine relationships between the severity of OSA and potential risk factors. In addition to the survey, 233 men and women participated in a Level 3 one-night home sleep test. Of those, 105 (45.1%) participants were reported to have obstructive sleep apnea (AHI ≥ 5). Mild and moderately severe OSA (AHI ≥ 5 to <30) was present in 39.9% and severe OSA (AHI ≥ 30) was identified in 5.2% of participants. Being male, being obese, and snoring loudly were significantly associated with severity of OSA. The severity of OSA in one First Nation appears relatively common and may be related to mainly individual factors such as loud snoring, obesity, and sex.

Duration and quality of sleep in 2 rural Cree First Nation communities in Saskatchewan, Canada.

STUDY OBJECTIVES: Estimates of sleep duration and quality are lacking for Canadian First Nations peoples. This study examines the prevalence of and risk factors for short/normal/long sleep duration and sleep quality. METHODS: Five hundred eighty-eight adults participated in the baseline survey of the First Nations Sleep Health Project conducted in 2018-2019 in Saskatchewan, Canada. Sleep duration and quality were self-reported. RESULTS: Mean sleep duration was 8.18 hours per night. About 45.5% slept the recommended 7 hours per night. However, short sleep duration and poor sleep quality were relatively common: about one-quarter of the participants slept fewer hours than recommended. Sleep duration was significantly less for men than women. Women were significantly more likely to report poor sleep quality than males. Multiple regression models revealed that age was significantly related with shorter sleep duration; sex and employment status were significantly related with sleep duration; and sex and income indicators were significantly associated with sleep quality. Nearly half of participants reported having had the recommended hours of sleep, but nearly two-thirds reported poor sleep quality. CONCLUSIONS: Information about the proportion of First Nations adults who sleep the recommended duration and the quality of sleep is important in informing health care and health policy.

What Happens to the Worried Well? Follow-Up of Subjective Cognitive Impairment.

BACKGROUND: Increasing concern around perceived neurocognitive decline is increasing the number of referrals to specialists and anxiety for patients. We aimed to explore the likelihood of the "worried well" experiencing neurocognitive decline and developing a neurological diagnosis. METHODS: A total of 166 "worried well" patients who attended the Rural and Remote Memory Clinic (RRMC) between 2004 and 2019 were included in this study. Demographic, health, social, and behavioral factors were measured at the initial visit. Mini-Mental State Examination (MMSE), Center for Epidemiologic Studies Depression Scale (CESD), and Functional Activities Questionnaire (FAQ) scores were measured and compared at initial assessment and at 1-year follow-up. MMSE scores over time were assessed with a mean follow-up of 2.95 years (SD 2.87). RESULTS: No statistically significant difference was seen in MMSE, CESD, or FAQ scores when comparing clinic day to 1-year follow-up, and no consistent pattern of MMSE score over time was seen. Of the 166 patients with subjective cognitive impairment (SCI) on initial assessment, 5 were diagnosed with Alzheimer's disease (AD) at 8.5, 3.5, 5, 3, and 1.75 years; 2 were diagnosed with MCI at 1 and 2 years; 1 was diagnosed with vascular cognitive impairment at 5 years; and 1 was diagnosed with frontotemporal dementia (FTD) at 0.5 years. CONCLUSION: The likelihood of a patient with SCI developing a neurological diagnosis is reassuringly low (9/166), but not irrelevant. This, along with the benefits of early diagnosis and treatment for dementia, leads us to believe that patients with SCI should still be seen in follow-up at least at the 1-year mark.

Seasonal Changes in Sleep Patterns in Two Saskatchewan First Nation Communities.

Sleep is crucial for maintaining the recovery and restoration of the body and brain. Less sleep is associated with poor mental and physical performance. Seasonal changes in sleep patterns can be observed. This paper examines seasonal effects on sleep timing, duration, and problems in two Cree First Nation communities in Saskatchewan, Canada. Data were available from a community survey of 588 adults aged 18 years and older (range: 18-78 years) with 44.2% males and 55.8% females. Results are presented using descriptive statistics and a binary logistic-regression model to identify the association between seasonal changes in sleep patterns, and demographic, social, and environmental factors. The participants reported sleeping the least during the spring and summer months and sleeping the most during the fall and winter months. This was further confirmed by sleep hours and the lower proportion of recommended hours of sleep during the spring and summer, and a higher proportion of longer sleep duration during the fall and winter months. There was no significant variation in sleeping onset and wake-up times by season. Overall, there were no significant differences in the prevalence of sleep deprivation, insomnia, and excessive daytime sleepiness by season. When stratified by age group and sex, some differences existed in the prevalence of sleep problems by season. More than two-thirds (68.6%) of the participants reported that there was a change in sleep patterns across seasons, and about 26.0% reported a very or extremely marked change in sleep patterns across seasons. Changes in sleep patterns by season were related to money left at the end of the month and damage caused by dampness in the house.

Sleep deprivation in two Saskatchewan First Nation communities: a public health consideration.

OBJECTIVES: Sleep deprivation is a common problem in Canada and is associated with many health problems. More than a quarter of Canadians get fewer than the recommended sleep hours (<7 h). This paper examines the prevalence and risk factors for sleep deprivation in two First Nation communities in Saskatchewan, Canada. METHODS: The baseline cross-sectional survey was completed between 2018 and 2019 in collaboration with the two Cree First Nation communities in Saskatchewan, Canada. There were five hundred and eighty-eight participants participated in the survey from two communities. A Multivariate logistic regression model was used for analysis. RESULTS: The prevalence of sleep deprivation (<7 h of sleep) was 25.4%. The multivariate logistics regression revealed that middle and older age groups, visible mold in the house, and being male with nighttime insomnia symptoms were significantly associated with a higher risk of sleep deprivation among study participants in the study. CONCLUSIONS: In these two First Nation communities, a higher proportion of the participants reported having sleep deprivation. This was a unique study, which evolved from ongoing research collaboration with two First Nation communities in Saskatchewan, Canada. Findings will be helpful in the management of patients with sleep deprivation in these communities; as well as for co-creating policy with the communities and future research priorities.

Associations between Housing Factors and Respiratory Symptoms in Two Saskatchewan First Nations Communities.

Inadequate housing is commonplace in First Nations in Canada, often leading to environmental impacts on housing such as dampness and mold. First Nations communities suffer from a higher prevalence of respiratory-related health conditions than the general Canadian population. There is limited Canadian literature evaluating the relationship between housing factors and the respiratory health of adults within First Nations communities. This study was undertaken with two Saskatchewan First Nations communities. The study population consisted of 293 individuals within 131 households. The individuals completed questionnaires on their general and respiratory health, and one member of each household completed a household questionnaire. The collection of environmental samples from within the house was undertaken. The respiratory outcomes of interest focused on the individuals with ever wheeze, reported by 77.8% of the individuals, and shortness of breath, reported by 52.6% of the individuals. Body mass index, the nontraditional use of tobacco (i.e., current and ex-smoking), the nontraditional use of tobacco in the house (i.e., smoking in the house), dampness in the house in the last 12 months, and always having a smell of mold in the house were significantly associated with respiratory symptoms. The results reveal that respiratory symptom rates were high in the population and housing factors were significantly associated with respiratory symptoms. Addressing and redressing housing inadequacies in First Nations communities are important in preventing additional burdens to health.

Prevalence of Insomnia in Two Saskatchewan First Nation Communities.

Insomnia is a common problem in Canada and has been associated with increased use of health care services and economic burden. This paper examines the prevalence and risk factors for insomnia in two Cree First Nation communities in Saskatchewan, Canada. Five hundred and eighty-eight adults participated in a baseline survey conducted as part of the First Nations Sleep Health Collaborative Project. The prevalence of insomnia was 19.2% among participants with an Insomnia Severity Index score of ≥15. Following the definition of nighttime insomnia symptoms, however, the prevalence of insomnia was much higher, at 32.6%. Multivariate logistic regression modeling revealed that age, physical health, depression diagnosis, chronic pain, prescription medication use for any health condition, and waking up during the night due to terrifying dreams, nightmares, or flashbacks related to traumatic events were risk factors for insomnia among participants from two Saskatchewan Cree First Nation communities.

The importance of organizational commitment in rural nurses' intent to leave.

AIMS: To examine determinants of intention to leave a nursing position in rural and remote areas within the next year, for Registered Nurses or Nurse Practitioners (RNs/NPs) and Licensed Practical Nurses (LPNs). DESIGN: A pan-Canadian cross-sectional survey. METHODS: The Nursing Practice in Rural and Remote Canada II survey (2014-2015) used stratified, systematic sampling and obtained two samples of questionnaire responses on intent to leave from 1,932 RNs/NPs and 1,133 LPNs. Separate logistic regression analyses were conducted for RNs/NPs and LPNs. RESULTS: For RNs/NPs, 19.8% of the variance on intent to leave was explained by 11 variables; and for LPNs, 16.9% of the variance was explained by seven variables. Organizational commitment was the only variable associated with intent to leave for both RNs/NPs and LPNs. CONCLUSIONS: Enhancement of organizational commitment is important in reducing intent to leave and turnover. Since most variables associated with intent to leave differ between RNs/NPs and LPNs, the distinction of nurse type is critical for the development of rural-specific turnover reduction strategies. Comparison of determinants of intent to leave in the current RNs/NPs analysis with the first pan-Canadian study of rural and remote nurses (2001-2002) showed similarity of issues for RNs/NPs over time, suggesting that some issues addressing turnover remain unresolved. IMPACT: The geographic maldistribution of nurses requires focused attention on nurses' intent to leave. This research shows that healthcare organizations would do well to develop policies targeting specific variables associated with intent to leave for each type of nurse in the rural and remote context. Practical strategies could include specific continuing education initiatives, tailored mentoring programs, and the creation of career pathways for nurses in rural and remote settings. They would also include place-based actions designed to enhance nurses' integration with their communities and which would be planned together with communities and nurses themselves.

Domestic Risk Factors for Atopic and non-Atopic Asthma in First Nations Children Living in Saskatchewan, Canada.

Both allergic and non-allergic asthma phenotypes are thought to vary by specific housing and other indoor environmental conditions. This study evaluated risk factors for allergic asthma phenotypes in First Nation children, an understudied Canadian population with recognized increased respiratory morbidity. We conducted a cross-sectional survey with a clinical component to assess the respiratory health of 351 school-age children living on two rural reserve communities. Asthma was defined as parental report of physician diagnosed asthma or a report of wheeze in the past 12 months. Atopy was determined by a ≥ 3-mm wheal response to any of six respiratory allergens upon skin prick testing (SPT). Important domestic and personal characteristics evaluated included damp housing conditions, household heating, respiratory infections and passive smoking exposure. Asthma and atopy prevalence were 17.4% and 17.1%, respectively. Of those with asthma, 21.1% were atopic. We performed multivariate multinomial logistic regression modelling with three outcomes: non-atopic asthma, atopic asthma and no asthma for 280 children who underwent SPT. After adjusting for potential confounders, children with atopic asthma were more likely to be obese and to live in homes with either damage due to dampness (p < 0.05) or signs of mildew/mold (p = 0.06). Both natural gas home heating and a history of respiratory related infections were associated with non-atopic asthma (p < 0.01). Domestic risk factors for asthma appear to vary by atopic status in First Nations children. Determining asthma phenotypes could be useful in environmental management of asthma in this population.

Lung Function Decline in Farm and Nonfarm Rural Residents of Saskatchewan.

OBJECTIVE: This study aims to assess the annual changes in lung function among farm and nonfarm adult residences in rural Saskatchewan, Canada. METHODS: Data from the Saskatchewan Rural Health Study survey (2010 to 2014) among 724 adults were used. RESULTS: For forced expiratory volume in 1 second (FEV1) measurements, estimates of annual decline (in milliliters) were highest in older age male (65+ years) (Mean, SD) (-42.63, 21.16); and among old heavy smokers (-57.79, 24.30). Estimates of annual decline in forced vital capacity (FVC) were highest in current smokers without the use of natural gas (-25.78, 14.78) and among old heavy smokers (-33.88, 20.28). Living on a farm is associated with decreased FEV1 and FVC, but not statistically significant by sex and age. CONCLUSIONS: A complex mix of personal and contextual factors may affect these estimates.

The Mosaic of Primary Care Nurses in Rural and Remote Canada: Results from a National Survey.

BACKGROUND|OBJECTIVE: Nurses provide essential primary care (PC) in rural and remote Canada. We examined the practice context and responsibilities of this little-known understudied workforce. METHOD: Data from Nursing Practice in Rural and Remote Canada II, a 2014 to 2015 pan-Canadian survey, were analyzed. RESULTS: Of 3,822 respondents, 192 identified that PC was their only practice focus (PC-Only), and for 111, it was one focus among others (PC-Plus). Proportionally more PC-Only than PC-Plus nurses had graduate education, were employed in larger communities and had experienced higher job resources and lower job demands. Proportionally fewer PC-Only than PC-Plus nurses followed protocols/decision support tools, dispensed medications and provided emergency services. Proportionally more PC-Only than PC-Plus nurses ordered advanced diagnostic tests/imaging, and fewer PC-Only than PC-Plus nurses performed and interpreted laboratory tests and diagnostic imaging on site. CONCLUSION: Contributions of the rural and remote nursing workforce to PC are rendered invisible by contemporary characterizations of the PC workplace, limiting evaluation and improvement efforts.

Prevalence and determinants of asthma among aboriginal adolescents in Canada.

Objective: The objective of the study was to determine the prevalence and associated risk factors of asthma in Aboriginal adolescents in Canada based on the Canadian Aboriginal Peoples Survey (APS) 2012. Few studies have investigated the prevalence and risk factors of asthma in Aboriginal adolescents in Canada. Methods: Data from the cross-sectional APS 2012 were analyzed to accomplish the objective. Logistic regression analysis was utilized to determine significant risk factors of lifetime diagnosis of asthma among Aboriginal adolescents. The outcome of interest for adolescents was based on the question: "Do you have asthma that have been diagnosed by a health professional?" Individual, environmental, and contextual factors were tested for an association with lifetime diagnosis of asthma among adolescents. Results: The overall prevalence of lifetime diagnosis of asthma was 16.0%. The prevalence of lifetime diagnosis of asthma was 16.8% for adolescent boys and 15.3% for adolescent girls. Based on multivariable logistic regression analysis, the risk factors of lifetime diagnosis of asthma were: age, income, being overweight, smoking inside the home, having one to two children under 18 years in the household, history of bronchitis, living in an urban residence, education, and geographical location. Female sex was reported to have a protective effect on or reduce risk of the prevalence of lifetime diagnosis of asthma compared to the male sex. Conclusions: Lifetime diagnosis of asthma prevalence appears to be lower in Aboriginal adolescent girls than in adolescent boys. Lifetime diagnosis of asthma prevalence in these adolescents is associated with age, income, education, being overweight, smoking inside the home, history of bronchitis, and location of residence, both geographical region and urban residence. The prevalence of lifetime diagnosis of asthma among Aboriginal adolescent is higher compared to the general adolescent population in Canada.

Rural and Remote Registered Nurses' Perceptions of Working Beyond Their Legislated Scope of Practice.

Registered nurses (RNs) enact their scope of practice in everyday practice through the influences of client needs, the practice setting, employer requirements and policies and the nurse's own level of competence (Canadian Nurses Association 2015). A scope of practice is "dynamic and responsive to changing health needs, knowledge development and technological advances" (International Council of Nurses 2013). In Canada, RNs' scope of practice is set out through provincial and territorial legislation and provincial regulatory frameworks, which are broadly consistent, but vary across provinces (Schiller 2015). Provincial and territorial regulatory bodies articulate the RN scope through frameworks that include expected standards as well as, in some jurisdictions, limits and conditions upon practice (British Columbia College of Nursing Professionals 2018), and which are commonly referred to as a licensed or registered scope of practice. Rural and remote practice is starting to be explicitly acknowledged within nurses' legislated scopes of practice through the identification of certified practices for RNs in specific rural and remote practice settings, following approved education (British Columbia College of Nursing Professionals 2018).

Rural and Remote Licensed Practical Nurses' Perceptions of Working Below Their Legislated Scope of Practice.

Over the past two decades in Canada, licensed or registered practical nurses (LPNs) have experienced an extension of their educational preparation and scope of practice. Simultaneously, there has been an increase in the number of LPNs employed in rural and remote communities. These changes have influenced the practice environment and LPNs' perceptions of their work. The aim of this article is to examine what factors predict rural and remote LPNs' perceptions of working below their legislated scope of practice and to explore their perceptions of working below scope. The findings arise from a national survey of rural and remote regulated nurses, in which 77.3% and 17.6% of the LPNs reported their practice as within and as below their legislated scope of practice, respectively. Three factors, age, stage of career and job-resources related to autonomy and control, predicted that LPNs would perceive themselves to be working below their scope of practice. These results suggest that new ways to communicate nurses' scope of practice are needed, along with supports to help rural and remote LPNs more consistently practice to their legislated scope of practice. Without such changes, the LPN role cannot be optimized and disharmony within rural and remote settings may be exacerbated.

Development and psychometric evaluation of the Job Demands in Nursing Scale and Job Resources in Nursing Scale: Results from a national study.

AIM: To develop and test the psychometric properties of the Job Resources in Nursing (JRIN) Scale and the Job Demands in Nursing (JDIN) Scale. DESIGN: Cross-sectional survey. METHODS: A three-phase process of instrument development and psychometric evaluation was employed: Phase 1: development of a 42-item JRIN Scale and 60-item JDIN Scale through extensive literature review, expert consultation and an iterative content evaluation; Phase 2: pilot survey of 89 nurses and use of item discrimination analysis to estimate the internal consistency reliability of each subscale and reduce the length of each scale; Phase 3: Modified scales were tested in a nationwide survey of 3,822 rural/remote nurses, including use of exploratory factor analysis. RESULTS: The 24 items related to job resources favoured a six-factor structure, accounting for 63% of the variance, Cronbach's alpha 0.88. The 22 items related to job demands favoured a six-factor structure, accounting for 59% of the variance, Cronbach's alpha 0.84.

Incidence and Longitudinal Changes in Prevalence of Chronic Bronchitis in Farm and Non-Farm Rural Residents of Saskatchewan.

OBJECTIVE: To assess the predictors associated with incidence and longitudinal changes in the prevalence of chronic bronchitis (CB) among farm and non-farm residents of rural Saskatchewan, Canada. METHODS: The Saskatchewan Rural Health Study was a prospective study of the lung health of rural dwellers. We obtained information on 4624 households, 8261 individuals (2797 households, 4867 individuals) at baseline (follow-up). RESULTS: Incidence of CB was 4.3% over 4 years. The prevalence was 6.4% and 5.3% (baseline) and 12.1% and 9.2% (follow-up) in non-farm and farm residents, respectively. The prevalence of CB was associated with current smokers; father ever had lung trouble; obesity; mother smoked during pregnancy; allergic reaction to cats and to pollen; household income inadequacy and age. CONCLUSION: Prevalence and incidence of CB in rural people appear to be a complex mix of personal and contextual factors.
