The quality, effectiveness and efficiency of health care can now be measured and monitored with information technology. This has created new opportunities and challenges for Canada's health record professionals. Recently the Canadian Health Record Association developed a new role statement to clarify and redefine the future role of the health record professional. This article describes the process used and the conclusions.

OBJECTIVE: To examine the influence of cardiac patients' demographic and health characteristics on physicians' cardiac rehabilitation (CR) referral practice and patients' attendance at such programs. DESIGN: A retrospective, systematic review of consecutive health records. SETTING: A tertiary care centre and the two associated CR programs in a Western Canadian city. PATIENTS: One thousand, three hundred and twenty-eight adult patients (21 years of age or older) discharged following acute myocardial infarction, percutaneous transluminal coronary angioplasty (PTCA) and/or coronary artery bypass graft surgery between September 1, 1996 and August 31, 1997. MAIN RESULTS: There were 1245 surviving patients. Evidence of attendance at a CR program was 28.4%, while auditable evidence of referral to a CR program was 23.9%. Stepwise logistic regression revealed that ability to speak English (OR 9.56) living in a city (OR 3.97) and current smoking (OR 1.51) were associated with an increased likelihood, whereas having a history of chronic obstructive pulmonary disease or asthma (OR 0.53), being 70 years of age or older (OR 0.42), having a current admission for PTCA (OR 0.32) and having a history of neurological or cognitive impairment (OR 0.26) were associated with a decreased likelihood of CR attendance. Sex, nature of coronary artery disease risk factors, incidence of postevent complications and pre-event cardiac status (including New York Heart Association status and number of previous events) were not associated with patients' CR attendance. CONCLUSIONS: This study suggests that there is an inconsistent and poorly documented approach to referral of patients to CR programs for reasons that remain unclear. These findings provide a foundation for development and testing of enhanced referral mechanisms and of innovative means to provide rehabilitation services to patients who are at risk for not being referred to or attending CR programs.
Diagnostic codes are computer-readable descriptors of patients' conditions contained in computerized patient records. The codes uniquely identify the diagnoses or conditions identified at initial or follow-up examinations that are otherwise written in English or French on the patient chart. Dental diagnostic codes would allow dentists to access information on the types and range of conditions they encounter in their practices, enhance patient communication, track clinical outcomes and monitor best practices. For the profession, system-wide use of the codes could provide information helpful in understanding the oral health of Canadians, demonstrate improvements in oral health, track best practices system-wide, and identify and monitor the progress of high-need groups in Canada. Different systems of diagnostic codes have been implemented by program managers in Germany, the United Kingdom and North America. In Toronto, the former North York Community Dental Services developed and implemented a system that follows the logic used by the Canadian Dental Association for its procedure codes. The American Dental Association is now preparing for the release of SNODENT codes. The addition of diagnostic codes to the service codes already contained in computerized patient records could allow easier analysis of the rich evidence available on the oral health and oral health care of Canadians, thereby enhancing our ability to continuously improve patient care.

This study evaluated whether oral disorders were associated with chronic systemic diseases in 532 Canadian adults who are old and very old and living in institutions. A brief oral examination documented tooth retention, caries, and periodontal and gingival health. Medical records provided information about chronic systemic conditions. A history of stroke was associated with a higher experience of caries, a higher ratio of decayed-to-present teeth, and more gingival and periodontal problems. Participants with high blood pressure, osteoporosis, or diabetes were more likely to be edentulous or to have fewer teeth than participants who did not have these conditions. Participants who had arthritis retained more teeth with age. Participants who had more diseases also tended to have poorer gingival or periodontal conditions, fewer teeth, and higher risk of edentulousness. The associations between systemic diseases and more severe oral disorders may be direct or may be mediated by underlying factors such as health behaviors.
BACKGROUND: Affective disorders present an important clinical challenge in multiple sclerosis (MS). Due to prohibitive sample size requirements, population-based studies have not yet provided an adequate description of the underlying epidemiology of this association. OBJECTIVE: To describe the epidemiology of affective disorders in MS in a general population sample. METHODS: The study presented here accessed administrative data from a universal healthcare insurance plan in the Canadian province of Alberta. Physician billing data recorded in the Alberta Health Care Insurance Plan was used to identify members of the population >15 years of age with and without MS. Crude and stratified estimates of the association between affective disorders and MS were made. Logistic regression analysis was used to evaluate statistical interactions and to provide adjusted estimates of the association. RESULTS: The estimated prevalence of MS in the population within the targeted age range (2.3 million individuals) was 386/100,000 and that of affective disorders was 7.7%. As expected, an association between MS and affective disorders was identified (crude relative prevalence: 2.2). The association varied in strength over age-sex categories. Although the prevalence of affective disorder was higher in women with MS than men with MS, the association of MS with affective disorders was stronger in men. The strength of association declined with age in both men and women. Affective disorder prevalence in people with MS becomes similar to that of the general population in older age groups. CONCLUSION: Affective disorders occur with an increased frequency in MS. This is true in men and women and across all relevant age groups, although the association gets weaker with advancing age. Higher frequencies of affective disorder occur in women with MS than in men with MS. The frequency of affective disorder in people with MS is highest in the 25-44 age group, and declines in older age categories.
BACKGROUND: Research in statistical methods is essential for maintenance of high quality of the published literature. OBJECTIVE: To update previous reports of the types and frequencies of statistical terms and procedures in research studies of selected professional pharmacy journals. METHODS: We obtained all research articles published in 2001 in 6 journals: American Journal of Health-System Pharmacy, The Annals of Pharmacotherapy, Canadian Journal of Hospital Pharmacy, Formulary, Hospital Pharmacy, and Journal of the American Pharmaceutical Association. Two independent reviewers identified and recorded descriptive and inferential statistical terms/procedures found in the methods, results, and discussion sections of each article. Results were determined by tallying the total number of times, as well as the percentage, that each statistical term or procedure appeared in the articles. RESULTS: One hundred forty-four articles were included. Ninety-eight percent employed descriptive statistics; of these, 28% used only descriptive statistics. The most common descriptive statistical terms were percentage (90%), mean (74%), standard deviation (58%), and range (46%). Sixty-nine percent of the articles used inferential statistics, the most frequent being chi(2) (33%), Student's t-test (26%), Pearson's correlation coefficient r (18%), ANOVA (14%), and logistic regression (11%). CONCLUSIONS: Statistical terms and procedures were found in nearly all of the research articles published in pharmacy journals. Thus, pharmacy education should aim to provide current and future pharmacists with an understanding of the common statistical terms and procedures identified to facilitate the appropriate appraisal and consequential utilization of the information available in research articles.
BACKGROUND: Lack of an association between area-based socioeconomic status (SES) and readmission for asthma was investigated in a country with a universal health care system. METHODS: Data linkage analysis was conducted based on hospitalization data from Statistics Canada's Person-oriented Information Database and area-based SES data from the 1996 Census. Hospital records for 8333 asthma patients aged 20-64 years in all Canadian provinces except Quebec who were admitted in 1995/1996 were linked to determine the number of patients who were rehospitalized within the same fiscal year. The area-based SES of the patients was defined according to the average personal income and proportion of residents with a university degree in an enumeration area (EA). Incidence rates of readmission for asthma were calculated based on the total years at risk. Cox's proportional hazard model was used to adjust for age, sex, province, and length of stay for first admission. RESULTS: The incidence rate of asthma rehospitalization was 31.6 per 100 person-years for men and 37.2 per 100 person-years for women. Neither average EA income or education level was significantly associated with rehospitalization for asthma. Women living in poor areas tended to have an increased incidence of asthma rehospitalization, but the difference was not significant after adjustment for covariates using the Cox regression model. CONCLUSION: Socioeconomic status measured at the neighborhood level has no significant impact on rehospitalization for asthma among Canadian adults.
OBJECTIVE: The prevalence of overweight and obesity in children is rising. Childhood obesity is associated with many negative social and psychological ramifications such as peer aggression. However, the relationship between overweight and obesity status with different forms of bullying behaviors remains unclear. The purpose of this article is to examine these relationships. METHODS: We examined associations between bullying behaviors (physical, verbal, relational, and sexual harassment) with overweight and obesity status in a representative sample of 5749 boys and girls (11-16 years old). The results were based on the Canadian records from the 2001/2002 World Health Organization Health Behaviour in School-Aged Children Survey. Body mass index (BMI) and bullying behaviors were determined from self-reports. RESULTS: With the exception of 15- to 16-year-old boys, relationships were observed between BMI category and peer victimization, such that overweight and obese youth were at greater relative odds of being victims of aggression than normal-weight youth. Strong and significant associations were seen for relational (eg, withdrawing friendship or spreading rumors or lies) and overt (eg, name-calling or teasing or hitting, kicking, or pushing) victimization but not for sexual harassment. Independent of gender, there were no associations between BMI category and bully-perpetrating in 11- to 14-year-olds. However, there were relationships between BMI category and bully-perpetrating in 15- to 16-year-old boys and girls such that the overweight and obese 15- to 16-year-olds were more likely to perpetrate bullying than their normal-weight classmates. Associations were seen for relational (boys only) and overt (both genders) forms of bully-perpetrating but not for sexual harassment. CONCLUSIONS: Overweight and obese school-aged children are more likely to be the victims and perpetrators of bullying behaviors than their normal-weight peers. These tendencies may hinder the short- and long-term social and psychological development of overweight and obese youth.
OBJECTIVES: People in lower socio-economic groups are more likely to experience disability and cognitive impairments at earlier ages than those in higher status groups. As a result, the need for nursing home care would be expected to be greater among older people of lower socio-economic status. This study examines the effects of income and education on the probability of nursing home entry in a universally insured elderly population. METHODS: Using a prospective observational study design, a range of predictors of nursing home admission was examined over a three-year period in a representative sample of 7220 residents, aged 60 years or older, in a Canadian province. Individual census records and computerized administrative records of health care utilization were linked to form a database for analysis. RESULTS: An increased risk of institutionalization was associated with older age, male gender, unmarried status and self-reported disability. In addition, lower household income and lower attained education were independently associated with a higher risk of nursing home admission. CONCLUSIONS: These results emphasize the independent role of socio-economic status in accentuating or accelerating the need for institutional care towards the end of life. It is important that these effects are recognized in policies that determine the finance of both nursing home care and formal community-based supportive care.
Questionnaire surveys in several countries have consistently detected an association between symptoms and residential mould growth. Confirmation by objective measures would strengthen the argument for causality. To address this issue, quantitative and qualitative fungal measures (airborne ergosterol and viable fungi in dust) were compared to respiratory symptoms (n = 403) and nocturnal cough recordings (n = 145) in Canadian elementary schoolchildren during the winter of 1993-1994. There was a 25 percent to 50 percent relative increase in symptom prevalence when mould was reported to be present (p < 0.05). However, neither symptoms nor recorded cough was related to objective measures of mould. In conclusion, the inability to find an association between objective measures of fungus and health suggest that either these objective measures, or the traditionally used questionnaire data are inaccurate. This discrepancy limits the acceptance of a causal relation between indoor fungal growth and illness.
OBJECTIVE: To describe the distribution of weight and abdominal obesity among Canadian adults and to determine the association of obesity with other risk factors for cardiovascular disease. DESIGN: Population-based cross-sectional surveys. Survey nurses administered a standard questionnaire and recorded two blood pressure measurements during a home visit. At a subsequent visit to a survey clinic two further blood pressure readings were made, anthropometric measurements recorded and a blood specimen taken for plasma lipid determination. SETTING: Nine Canadian provinces, from 1986 to 1990. PARTICIPANTS: A probability sample of 26,293 men and women aged 18 to 74 years was selected from the health insurance registration files of each province. Anthropometry was performed on 17,858 subjects. OUTCOME MEASURES: Body mass index (BMI), ratio of waist to hip circumference (WHR), mean plasma lipid levels, prevalence of high blood pressure (diastolic greater than or equal to 90 mm Hg or patient on treatment) and self-reported diabetes mellitus. MAIN RESULTS: The prevalence of obesity (BMI greater than or equal to 27) increased with age and was greater in men (35%) than in women (27%). Abdominal obesity was likewise higher in men and increased with both age and BMI. The prevalence of high blood pressure was greater in those with higher BMI, especially in those with a high WHR. Although total plasma cholesterol levels increased only modestly with BMI, levels of low density lipoprotein (LDL) cholesterol and triglycerides and the ratio of total cholesterol to high density lipoprotein (HDL) cholesterol increased steadily, while HDL-cholesterol decreased consistently with increasing BMI. High total cholesterol levels (greater than or equal to 5.2 mmol/L) were more prevalent among people with high BMI, especially those with a high WHR. The prevalence of diabetes increased with BMI among those 35 years or older, especially those with abdominal obesity. About half of men and two-thirds of women who were obese were trying to lose weight. CONCLUSION: Obesity remains common among Canadian adults. There is a need for broad-based programs that facilitate healthy eating and activity patterns for all age groups. Health professionals should incorporate measurement of BMI and WHR into their routine examinations of patients to enhance their evaluation of health risk.
