The Saskatchewan health and back pain survey. The prevalence of low back pain and related disability in Saskatchewan adults.

STUDY DESIGN: Population-based, cross-sectional, mailed survey. OBJECTIVES: To determine the lifetime, 6-month period, and point prevalence of low back pain and its related disability among Saskatchewan adults and to investigate the presence and strength of selective response bias. SUMMARY OF BACKGROUND DATA: There have been many reports of the prevalence of low back pain in different populations, and the estimates vary widely depending on case definition. However, most studies fail to differentiate between trivial and disabling back pain, which raises the issue of the usefulness of these estimates. No studies have yet documented the prevalence of graded low back pain severity and its related disability in a North American, general, population-based survey. METHODS: The Saskatchewan Health and Back Pain Survey was mailed to a probability sample of 2184 Saskatchewan adults between 20 and 69 years of age. Fifty-five percent of the eligible population responded to the survey. Respondents were compared with nonrespondents, and the presence of selective response bias by back pain status was investigated by wave analysis. The point and lifetime prevalence of low back pain was determined by simple questions, and the 6-month period prevalence of low back pain was determined by the Chronic Pain Questionnaire. All estimates were age standardized to the Saskatchewan population. RESULTS: The authors estimate that at the time of the survey 28.4% (95% confidence interval, 25.6-31.1) of the Saskatchewan adult population were experiencing low back pain, and 84.1% (95% confidence interval, 81.9-86.3) had experienced it during their lifetime. Overall, 48.9% (95% confidence interval, 45.9-52.0) of the population had experienced low intensity/low-disability low back pain in the previous 6 months, 12.3% (95% confidence interval, 10.3-14.4) had experienced high-intensity/low-disability low back pain, and an additional 10.7% (95% confidence interval, 8.8-12.5) had experienced high-disability low back pain in the previous 6 months. There was little variation in the estimates over age groups, but women experienced more high-disability back pain than men. There was no evidence of selective response bias by low back pain status in the survey. CONCLUSION: Low-intensity/low-disability low back pain is a common problem in the general population. Approximately 11% of the adult population studied had been disabled by low back pain in the previous 6 months.

The Saskatchewan Health and Back Pain Survey. The prevalence of neck pain and related disability in Saskatchewan adults.

STUDY DESIGN: Population-based, cross-sectional mailed survey. OBJECTIVE: To determine the lifetime, period, and point prevalence of neck pain and its related disability among Saskatchewan adults and investigate the presence and strength of nonresponse bias. SUMMARY OF BACKGROUND DATA: In Europe, the lifetime and point prevalence of neck pain is almost as high as the prevalence of low back pain. Similarly, chronic neck pain is highly prevalent and a common source of disability in the working-age population. However, no studies specifically have documented the prevalence of neck pain and its related disability in North America. METHODS: The Saskatchewan Health and Back Pain Survey was mailed to 2184 randomly selected Saskatchewan adults aged 20-69 years. Fifty-five percent of the study population participated. The presence of nonresponse bias was investigated through logistic regression and wave analysis. The Chronic Pain Questionnaire was used to classify the severity of chronic neck pain. RESULTS: The age-standardized lifetime prevalence of neck pain is 66.7% (95% confidence interval, 63.8-69.5), and the point prevalence is 22.2% (95% confidence interval, 19.7-24.7). The age-standardized 6-month prevalence of low-intensity and low-disability neck pain is 39.7% (95% confidence interval, 36.7-42.7), whereas it is 10.1% (95% confidence interval, 8.2-11.9) for high-intensity and low-disability neck pain and 4.6% (95% confidence interval, 3.3-5.8) for significantly disabling neck pain. The prevalence of low-intensity and low-disability neck pain decreases with age. More women experience high-disability neck pain than men. Wave analysis suggests that the point prevalence and 6-month prevalence of high-intensity and low-disability neck pain are overestimated in this survey. CONCLUSION: This cross-sectional study shows that neck pain is highly prevalent in Saskatchewan and that it significantly disables 4.6% (95% confidence interval, 3.3-5.8) of the adult population.

Trends in incidence and mortality from acute myocardial infarction in Nova Scotia and Saskatchewan 1974 to 1985. The Nova Scotia-Saskatchewan Cardiovascular Disease Epidemiology Group.

OBJECTIVE: To compare trends in incidence and case fatality of acute myocardial infarction (AMI) in Nova Scotia and Saskatchewan, provinces with the highest and lowest rates, respectively. DESIGN: Provincial hospital separation files were linked with mortality files and searched to identify incident cases in 1977, 1981 and 1985. The diagnoses were validated on a random sample of hospital charts with discharge codes 410 and 411 to 414 of the International Classification of Diseases of the World Health Organization. RESULTS: In spite of persisting differences between Nova Scotia and Saskatchewan, standardized AMI mortality and incidence rates in males and females have decreased, although at a slower rate in Saskatchewan. In both provinces the greatest decrease has occurred in male deaths prior to any hospital admission--likely representing cases of sudden death. Excess mortality in Nova Scotia is due predominantly to out-of-hospital deaths. Case fatality rates have declined in both provinces. The proportion of definite and possible AMI was similar in Nova Scotia and Saskatchewan in 1977, but not thereafter. CONCLUSIONS: Along with a decline in ischemic heart disease mortality, there appears to be a decline in AMI incidence in Nova Scotia. Parallel studies of risk factor changes, interventive care and access to care are required to explain the observed phenomena.

The Saskatchewan Health and Back Pain Survey: the prevalence and factors associated with depressive symptomatology in Saskatchewan adults.

OBJECTIVES: To determine the one-week period prevalence of depressive symptomatology among Saskatchewan adults and to identify sociodemographic and health factors associated with depressive symptomatology. METHODS: The Saskatchewan Health and Back Pain Survey was mailed to an age-stratified random sample of adults. Of the 2,184 eligible subjects, 55% (n = 1131) responded to the survey. We report age-standardized prevalence estimates stratified by age, gender and spinal pain severity. Logistic regression was used to measure the presence and strength of association between various factors and depressive symptomatology. RESULTS: 22.2% (95% CI 19.6-24.9) of adults experienced depressive symptomatology during the previous week, with higher rates in younger adults, in females, and in those with disabling spinal pain. Depressive symptomatology was associated with age, income, smoking, health status, gastro-intestinal problems, headaches and spinal pain. CONCLUSIONS: Depressive symptomatology is common in the Saskatchewan adult population, and is related to age, pain severity and general health.

Understanding the determinants of health: key decision makers in Saskatchewan Health districts and Saskatchewan Health, 1998.

This research inquiry used qualitative and quantitative methods to examine how key decision makers from Saskatchewan health districts and Saskatchewan Health understand the determinants of health. The inquiry was based on the premise that key decision makers' understanding of the determinants of health, and the consensus regarding these understandings, hinder or facilitate dialogue, choice of effective strategies, and achievement of health promotion goals. Interviews indicated variation in perspective and emphasis regarding how key decision makers understand the determinants of health. A survey of key decision makers found: 1) inconsistencies in respondents' understanding of the determinants of health, particularly between stated beliefs and priorities for actions; and 2) that the degree of consensus among decision makers was higher for stated beliefs and lower for choices of action. Results indicate a need for clarification and consensus-building processes concerning the determinants of health, as well as for clear policies that foster consistency between beliefs and actions and minimize inappropriate or undesirable differences in interpretations.

Estimation of the incidence of acute myocardial infarction using record linkage: a feasibility study in Nova Scotia and Saskatchewan. Nova Scotia-Saskatchewan Cardiovascular Disease Epidemiology Group.

The impact of cardiovascular disease prevention and therapeutic interventions may be reflected in the incidence and case-fatality of acute myocardial infarction. Relevant data can be obtained from carefully planned surveillance studies or from existing administrative data. Utilization of the latter is facilitated by record linkage of computerized provincial, regional and national databases. The validity of these data, particularly with respect to diagnostic codes, must be ensured. We estimated the incidence of fatal and non-fatal acute myocardial infarction (AMI) in Nova Scotia and Saskatchewan for 1977. Hospital discharge records from the two provinces for 1977 were linked with the Canadian Mortality Database (Statistics Canada) for residents of the two provinces. Whether an episode was a recurrent or initial one, was determined by a retrospective search through 1974. A random sample of hospital charts was examined for diagnostic validity. A higher incidence of acute myocardial infarction was found in Nova Scotia than in Saskatchewan. The proportion of fatal episodes was higher in Nova Scotia with the greatest difference in mortality occurring in deaths before formal hospitalization. Evaluation of cardiovascular health in the community, including an assessment of time trends as well as regional and provincial differences, is possible using routinely collected administrative data.

Compliance with refilling prescriptions for atypical antipsychotic agents and its association with the risks for hospitalization, suicide, and death in patients with schizophrenia in Quebec and Saskatchewan: a retrospective database study.

OBJECTIVE: The objective of this analysis was to describe the patterns of compliance with atypical antipsychotics among patients with schizophrenia in actual practice in 2 Canadian provinces and to examine the relation between degrees of compliance and the risks of hospitalization, suicide, and death. METHODS: Adults with a diagnosis of schizophrenia who filled at least 1 prescription for risperidone, olanzapine, or quetiapine were identified in the Quebec public prescription drug insurance plan database (from July 1, 2001, to December 31, 2004) and the Saskatchewan Health database (from January 1, 1999, to December 31, 2003). Compliance was assessed based on the medication possession ratio, which was estimated as the proportion of days for which medication was available over each month of follow-up (> or = 80% = good compliance; 50%-79% = moderate compliance; < 50% = poor compliance). The association between the early and long-term effects of compliance and the risks of hospitalization, suicide, and death were examined using Cox regression, with adjustment for baseline age, sex, and use of antidepressants, sedatives, and lithium (Quebec only). RESULTS: respective 41,754 and 3291 patients were identified from the Quebec and Saskatchewan databases. Approximately half of the patients in each cohort were male and were aged < 45 years. Many patients had good compliance over the full follow-up period (Quebec, 61%; Saskatchewan, 45%); however, poor compliance was seen in 23% of patients from Quebec and 34% of those from Saskatchewan. Compared with poor compliance, the long-term effect of good compliance was associated with a significantly decreased risk of all-cause hospitalization (Quebec: adjusted hazard ratio [HR] = 0.60; 95% CI, 0.57-0.64; Saskatchewan: adjusted HR = 0.81; 95% CI, 0.69-0.95) and psychosis-related hospitalization (Quebec: adjusted HR = 0.37; 95% Cl, 0.34-0.40; Saskatchewan: adjusted HR = 0.45; 95% CI, 0.32-0.64). The Quebec data also indicated a significant association between good versus poor compliance and a decreased risk of death (adjusted HR = 0.58; 95% CI, 0.51-0.66) and suicide (adjusted HR = 0.68; 95% CI, 0.55-0.84) that was not observed in Saskatchewan. CONCLUSION: In this retrospective analysis of patients with schizophrenia in Quebec and Saskatchewan, good compliance with atypical antipsychotic medications was associated with substantial reductions in the risk for all-cause and psychosis-related hospitalizations.

Mortality study of Canadian male farm operators: cancer mortality and agricultural practices in Saskatchewan.

The present investigation involved an analysis of approximately 70,000 male Saskatchewan farm operators, a subset of the 365,000 Canadian farm operators to be investigated in the Canadian Farm Operator Mortality Study. The results of the Saskatchewan analysis indicate that during the interval studied, overall mortality among Saskatchewan farmers was 25% lower than that for all Saskatchewan men, and that, during the same time interval, the risk of death from all types of cancer was also about 25% lower among Saskatchewan farmers than to all Saskatchewan men. Although the present study indicates that overall mortality of death from cancer was 25% lower among Saskatchewan male farmers, there was a relationship between non-Hodgkin's lymphoma mortality and acres sprayed for weeds; a similar risk relationship between expenditures on fuel oil and risk of death from non-Hodgkin's lymphoma was also evident. The magnitude of risk for Saskatchewan farmers is probably greater than that reflected in the estimates in this study, due to the likelihood of misclassification of exposure. There is a particular need for further studies in this area to improve the quantification of farming-related exposures, and to study the exposure history of individuals who develop non-Hodgkin's lymphoma.

Stabilization of an increasing trend in physician-diagnosed asthma prevalence in Saskatchewan, 1991 to 1998.

OBJECTIVES: To determine the prevalence of asthma, bronchitis, and COPD using the physician services database of the Saskatchewan Health Department from 1991 to 1998. DESIGN: Descriptive population-based study. SETTING: The Province of Saskatchewan, Canada. PARTICIPANTS: Residents of Saskatchewan covered by universal health care in the province. RESULTS: In all age groups, asthma prevalence increased between 1991 and 1995 and either was stable or declined between 1996 and 1998. Preschool children had the highest asthma prevalence during the study period, followed by children aged 5 to 14 years, young adults aged 15 to 34 years, and adults aged 35 to 64 years. Children aged 0 to 4 years and adults aged 35 to 64 years in the Registered Indian population had greater asthma prevalence than persons in other urban or rural populations during the study period. Asthma prevalence rates in rural populations were less than or similar to the rates of urban populations in all age groups during the study period. The prevalence of bronchitis was greater in the Registered Indian population than in urban and rural populations in all age groups throughout the study period. When persons who had visited a physician for bronchitis were excluded from the prevalence calculation, the original increases seen in asthma prevalence among very young children and older adults of Registered Indian origin disappeared, with the urban population having greater asthma prevalence in all age groups. In the Registered Indian population, adults aged 35 to 64 years had almost twofold increases in the prevalence of COPD in comparison to other Saskatchewan populations. CONCLUSIONS: Asthma prevalence, which had been on the increase in the 1980s and early 1990s, was either stable or declining during the latter part of 1990s in Saskatchewan. Preschool children and older adults from the Registered Indian population had greater asthma prevalence than did those from other Saskatchewan populations. Asthma prevalence among the rural populations was either similar or lower in comparison to the rates for the urban populations in all age groups during the study period. Further research is required to elucidate the findings in this study.

The Saskatchewan dissemination story.

The Saskatchewan Heart Health Program (SHHP) Dissemination Phase "Building Health Promotion Capacity" is a five-year program funded by Health Canada, Saskatchewan Health and the Heart and Stroke Foundation of Saskatchewan. This phase began in July 1998 and builds on two previous SHHP phases: the provincial heart health survey (Saskatchewan Health, 1990), and the community demonstration projects (SHHP, 1998a, b, c, d). The evolution of the SHHP has occurred in a dynamic provincial context. Saskatchewan is a Canadian prairie province of one million people with most living in the southern and central parts of the province. The population is ageing and urbanizing, and the economy is shifting away from agricultural production toward a diversified service sector. In 1993, health reform created 30 Districts in southern and central Saskatchewan; the formation of three northern Districts followed five years later. All but two Districts are rural-based. Population served ranges from 2,261 to 237,274; total area ranges from 4,019 to 133,900 square kilometers.

Comparison of anti-infective drug use in elderly persons in Manitoba, Nova Scotia, and Saskatchewan, Canada: relationship to drug insurance reimbursement policies.

BACKGROUND: Antimicrobial drug resistance continues to be a concern. Inappropriate use of antimicrobial agents is a well-documented contributory factor in the development of resistance. Canadian publicly funded drug insurance (pharmacare) programs have various approaches to reimbursement for antimicrobial drugs and promoting the appropriate prescribing of these agents. OBJECTIVE: The objective of this study was to examine changes in antimicrobial use over a 3-year period in relation to the reimbursement policies of the public drug insurance programs for elderly persons in Manitoba, Nova Scotia, and Saskatchewan. METHODS: The pharmacare databases of the 3 provincial drug insurance programs were accessed for fiscal years 1995/96, 1996/97, and 1997/98. Antimicrobial drug use was reported as mean age- and sex-standardized defined daily doses (DDDs) dispensed per 1000 beneficiaries per year. Provincial antimicrobial drug use was compared and related to provincial reimbursement policies. RESULTS: The rates and types of antimicrobial drugs dispensed to elderly beneficiaries of the Manitoba, Nova Scotia, and Saskatchewan pharmacare programs varied. Between fiscal years 1995/96 and 1997/98, DDDs of antimicrobials per 1000 beneficiaries per year decreased by 11.5% in Saskatchewan and increased by 1.2% in Manitoba and 6.2% in Nova Scotia. Rates of use of broadspectrum agents such as amoxicillin/clavulanate, azithromycin, clarithromycin, and fluoroquinolones were lower in the provinces that had reimbursement guidelines. Even when reimbursement policies were similar, as for fluoroquinolones in Manitoba and Saskatchewan, rates of use varied markedly, possibly as a result of the method of implementing the reimbursement guidelines. Use of fluoroquinolones, macrolides, penicillins, beta-lactamase-resistant penicillins, and tetracyclines was lower and use of sulfonamides and trimethoprim was greater in Saskatchewan than in Nova Scotia and Manitoba. CONCLUSIONS: The reimbursement guidelines of provincial drug insurance programs are among the factors affecting the use of antimicrobial agents. Both the type of reimbursement policy and the policy implementation mechanism affected the rate of utilization. Further research is needed to link drug-use information with data such as antimicrobial resistance patterns, diagnoses, physician visits, and hospitalizations.

Chest X-ray ordering related to varied clinical scenarios: a survey of Saskatchewan physicians.

INTRODUCTION: The chest X-ray (CXR) is one of the most commonly requested diagnostic imaging examinations. It is estimated that over 250,000 CXRs are ordered in Saskatchewan annually. Judicious use of the CXR is valuable in patient care, while unnecessary use increases costs, adds to patient irradiation, and may be in conflict with standards of patient care. In 1993, the Saskatchewan Health Services Utilization and Research Commission (HSURC) developed clinical practice guidelines (CPGs) for the CXR. These guidelines were based on a metaanalysis of validated literature. We were uncertain about whether Saskatchewan physicians were ordering CXRs based on the HSURC CXR CPGs. MATERIALS AND METHODS: A survey, based on recommendations from the HSURC CXR CPGs, was developed and distributed to 363 physicians in Saskatchewan by mail (30/363) and by email (333/363). The survey asked physicians if they would order, or not order, a CXR for 5 basic clinical scenarios. The question of whether to order a CXR was then repeated when the basic scenario was altered one variable at a time, to determine if the physicians would change their CXR orders. RESULTS: According to our assessment of physician responses to the initial clinical scenarios, the surveyed physicians correctly followed the HSURC CXR CPGs in the following frequencies: 100% scenario 1, 91.9% scenario 2, 35.4% scenario 3, 100% scenario 4, and 61.2% scenario 5. Alteration of the basic clinical scenarios resulted in very unpredictable ordering of CXRs by the survey participants. CONCLUSION: The Saskatchewan physicians we surveyed are not ordering CXRs on the basis of HSURC CXR CPGs. They order too many nonindicated CXRs. Further communication with, and education of, the physician population about the HSRUC CXR CPGs may be warranted.
