Influenza and seasonal patterns of hospital use by older adults in long-term care and community settings in Ontario, Canada.

OBJECTIVES: We compared seasonal influenza hospital use among older adults in long-term care (LTC) and community settings. METHODS: We used provincial administrative data from Ontario to identify all emergency department (ED) visits and hospital admissions for pneumonia and influenza among adults older than 65 years between 2002 and 2008. We used sentinel laboratory reports to define influenza and summer seasons and estimated mean annual event rates and influenza-associated rates. RESULTS: Mean annual pneumonia and influenza ED visit rates were higher in LTC than the community (rate ratio [RR] for influenza season = 3.9; 95% confidence interval [CI] = 3.8, 4.0; for summer = 4.9; 95% CI = 4.8, 5.1) but this was attenuated in influenza-associated rates (RR = 2.4; 95% CI = 2.1, 2.8). The proportion of pneumonia and influenza ED visits attributable to seasonal influenza was 17% (15%-20%) in LTC and 28% (27%-29%) in the community. Results for hospital admissions were comparable. CONCLUSIONS: We found high rates of hospital use from LTC but evidence of lower impact of circulating influenza in the community. This differential impact of circulating influenza between the 2 environments may result from different influenza control policies.

Oral vitamin B12 therapy in the primary care setting: a qualitative and quantitative study of patient perspectives.

BACKGROUND: Although oral replacement with high doses of vitamin B12 is both effective and safe for the treatment of B12 deficiency, little is known about patients' views concerning the acceptability and effectiveness of oral B12. We investigated patient perspectives on switching from injection to oral B12 therapy. METHODS: This study involved a quantitative arm using questionnaires and a qualitative arm using semi-structured interviews, both to assess patient views on injection and oral therapy. Patients were also offered a six-month trial of oral B12 therapy. One hundred and thirty-three patients who receive regular B12 injections were included from three family practice units (two hospital-based academic clinics and one community health centre clinic) in Toronto. RESULTS: Seventy-three percent (63/86) of respondents were willing to try oral B12. In a multivariate analysis, patient factors associated with a "willingness to switch" to oral B12 included being able to get to the clinic in less than 30 minutes (OR 9.3, 95% CI 2.2-40.0), and believing that frequent visits to the health care provider (OR 5.4, 95% CI 1.1-26.6) or the increased costs to the health care system (OR 16.7, 95% CI 1.5-184.2) were disadvantages of injection B12. Fifty-five patients attempted oral therapy and 52 patients returned the final questionnaire. Of those who tried oral therapy, 76% (39/51) were satisfied and 71% (39/55) wished to permanently switch. Factors associated with permanently switching to oral therapy included believing that the frequent visits to the health care provider (OR 35.4, 95% CI 2.9-432.7) and travel/parking costs (OR 8.7, 95% CI 1.2-65.3) were disadvantages of injection B12. Interview participants consistently cited convenience as an advantage of oral therapy. CONCLUSION: Switching patients from injection to oral B12 is both feasible and acceptable to patients. Oral B12 supplementation is well received largely due to increased convenience. Clinicians should offer oral B12 therapy to their patients who are currently receiving injections, and newly diagnosed B12-deficient patients who can tolerate and are compliant with oral medications should be offered oral supplementation.

A comparison of Canadian medical students from rural and non-rural backgrounds.

CONTEXT: Very little is known about medical students from rural areas currently enrolled in Canadian medical schools. PURPOSE: We aimed to compare rural and non-rural students in terms of demographics, socioeconomic status, financial status and career choices. METHODS: As part of a larger Internet survey of all students at Canadian medical schools outside Quebec, conducted in January and February 2001, we conducted post-hoc analyses to compare students from rural and non-rural areas. Canada Post's classification system was used to determine rural status. To compare differences between rural and non-rural students, we used logistical regression models for categorical variables and factorial analysis of variance for continuous variables. RESULTS: We received responses from 2994 (68.5%) of 4368 medical students. Eleven percent of Canadian medical students come from rural backgrounds. Rural students tend to be older and originate from families of lower socioeconomic status. Students from rural areas report higher levels of debt, increased rates of paid part-time and summer employment, and greater stress from their finances. Nevertheless, rural students are not more likely to state that financial considerations will affect their choice of specialty or practice location. CONCLUSIONS: Canadian medical students who come from rural backgrounds are different from their non-rural counterparts. Students from rural areas face numerous financial barriers in obtaining a medical education and report greater levels of financial stress. Medical schools should examine and address barriers to admission of rural students and they should consider directing more financial resources toward this financially vulnerable group.

Trends in influenza vaccination in Canada, 1996/1997 to 2005.

OBJECTIVES: This article reports recent trends in influenza vaccination rates in Canada, provides data on predictors of vaccination in Canada for 2005, and examines longer-term effects of Ontario's universal influenza immunization program on vaccine uptake. DATA SOURCES: Data are from the 1996/1997 National Population Health Survey (NPHS) and the 2000/2001, 2003, and 2005 Canadian Community Health Survey (CCHS). ANALYTICAL TECHNIQUES: NPHS and CCHS data were used to estimate influenza vaccination rates of the population aged 12 or older. The Z test was used to assess differences between surveys, and the chi-squared test for trend was used to examine trends over time. Logistic regression was used to identify predictors of vaccination and to compare the odds of being vaccinated in Ontario versus other provinces. MAIN RESULTS: Nationally, influenza vaccination rates rose from 15% in 1996/1997 to 27% in 2000/2001, stabilized between 2000/2001 and 2003, and increased further to 34% by 2005. Vaccination rates for most high-risk groups still fall short of national targets. Ontarians continue to be more likely to be vaccinated than are residents of any other province, while residents of two of the territories--Nunavut and the Northwest Territories--are even more likely to be vaccinated than are Ontarians.

The effect of universal influenza immunization on vaccination rates in Ontario.

OBJECTIVES: This article examines the association between introduction of Ontario's Universal Influenza Immunization Program and changes in vaccination rates over time in Ontario, compared with the other provinces combined. DATA SOURCES: The data are from the 1996/97 National Population Health Survey and the 2000/01 and 2003 Canadian Community Health Survey, both conducted by Statistics Canada. ANALYTICAL TECHNIQUES: Cross-tabulations were used to estimate vaccination rates for the total population aged 12 or older, for groups especially vulnerable to the effects of influenza, and by selected socio-demographic variables. Z tests and multiple logistic regression were used to examine differences between estimates. MAIN RESULTS: Between 1996/97 and 2000/01, the increase in the overall vaccination rate in Ontario was 10 percentage points greater than the increase in the other provinces combined. Increases in Ontario were particularly pronounced among people who were: younger than 65, more educated, and had a higher household income. Between 2000/01 and 2003, vaccination rates were stable in Ontario, while rates continued to rise in the other provinces. Even so, Ontario's 2003 rates exceeded those in the other provinces.

Effects of rising tuition fees on medical school class composition and financial outlook.

BACKGROUND: Since 1997, tuition has more than doubled at Ontario medical schools but has remained relatively stable in other Canadian provinces. We sought to determine whether the increasing tuition fees in Ontario affected the demographic characteristics and financial outlook of medical students in that province as compared with those of medical students in the rest of Canada. METHODS: As part of a larger Internet survey of all students at Canadian medical schools outside Quebec, conducted in January and February 2001, we compared the respondents from Ontario schools with those from the other schools (control group). Respondents were asked about their age, sex, self-reported family income (as a direct indicator of socioeconomic status), the first 3 digits of their postal code at graduation from high school (as an indirect indicator of socioeconomic status), and importance of financial considerations in choosing a specialty and location of practice. We used logistic regression models to see if temporal changes (1997 v. 2000) among Ontario medical students differed from those among medical students elsewhere in Canada apart from Quebec. RESULTS: Responses were obtained from 2994 (68.5%) of 4368 medical students. Across the medical schools, there was an increase in self-reported family income between 1997 and 2000 (p = 0.03). In Ontario, the proportion of respondents with a family income of less than $40,000 declined from 22.6% to 15.0%. However, compared with the control respondents, the overall rise in family income among Ontario students was not statistically significant. First-year Ontario students reported higher levels of expected debt at graduation than did graduating students (median $80,000 v. $57,000) (p < 0.001), and the proportion of students expecting to graduate with debt of at least $100,000 more than doubled. Neither of these differences was observed in the control group. First-year Ontario students were also more likely than fourth-year Ontario students to report that their financial situation was "very" or "extremely" stressful and to cite financial considerations as having a major influence on specialty choice or practice location. These differences were not observed in the control group. INTERPRETATION: At Canadian medical schools, there are fewer students from low-income families in general. However, Ontario medical students report a large increase in expected debt on graduation, an increased consideration of finances in deciding what or where to practise, and increasing financial stress, factors that are not observed among students in other provinces.

Characteristics of first-year students in Canadian medical schools.

BACKGROUND: The demographic and socioeconomic profile of medical school classes has implications for where people choose to practise and whether they choose to treat certain disadvantaged groups. We aimed to describe the demographic and socioeconomic characteristics of first-year Canadian medical students and compare them with those of the Canadian population to determine whether there are groups that are over- or underrepresented. Furthermore, we wished to test the hypothesis that medical students often come from privileged socioeconomic backgrounds. METHODS: As part of a larger Internet survey of all students at Canadian medical schools outside Quebec, conducted in January and February 2001, first-year students were asked to give their age, sex, self-described ethnic background using Statistics Canada census descriptions and educational background. Postal code at the time of high school graduation served as a proxy for socioeconomic status. Respondents were also asked for estimates of parental income and education. Responses were compared when possible with Canadian age-group-matched data from the 1996 census. RESULTS: Responses were obtained from 981 (80.2%) of 1223 first-year medical students. There were similar numbers of male and female students (51.1% female), with 65% aged 20 to 24 years. Although there were more people from visible minorities in medical school than in the Canadian population (32.4% v. 20.0%) (p < 0.001), certain minority groups (black and Aboriginal) were underrepresented, and others (Chinese, South Asian) were overrepresented. Medical students were less likely than the Canadian population to come from rural areas (10.8% v. 22.4%) (p< 0.001) and were more likely to have higher socioeconomic status, as measured by parents' education (39.0% of fathers and 19.4% of mothers had a master's or doctoral degree, as compared with 6.6% and 3.0% respectively of the Canadian population aged 45 to 64), parents' occupation (69.3% of fathers and 48.7% of mothers were professionals or high-level managers, as compared with 12.0% of Canadians) and household income (15.4% of parents had annual household incomes less than $40,000, as compared with 39.7% of Canadian households; 17.0% of parents had household incomes greater than $160,000, as compared with 2.7% of Canadian households with an income greater than $150,000). Almost half (43.5%) of the medical students came from neighbourhoods with median family incomes in the top quintile (p < 0.001). A total of 57.7% of the respondents had completed 4 years or less of postsecondary studies before medical school, and 29.3% had completed 6 or more years. The parents of the medical students tended to have occupations with higher social standing than did working adult Canadians; a total of 15.6% of the respondents had a physician parent. INTERPRETATION: Canadian medical students differ significantly from the general population, particularly with regard to ethnic background and socioeconomic status.

Sex differences in first-year students at Canadian medical schools.

OBJECTIVES: To compare male and female medical students by age, level of education before admission to medical school, race/ethnicity, parental education level, socioeconomic status, and attitudes toward public health care. METHODS: In 2001, we conducted an Internet-based survey of all students enrolled in the 16 medical schools across Canada. Based on the high response rate, first-year medical students at Canadian medical schools outside of Quebec were included in this analysis. The interactions between sex and age, years of premedical education, race/ethnicity, parental occupation, education and household income, impact of finances on choice of medical school, future specialty and practice location, attitudes toward private funding in the Canadian health care system were examined using descriptive statistics and chi2 tests. RESULTS: There were no significant differences between male and female medical students in age, level of education before admission, and race/ethnicity. Female students' fathers (p=.046) and mothers (p=.061) were more likely to hold positions of higher occupational status than were those of male students. There was no significant difference between the parental household incomes of male and female students. Male students were more likely than female students to state that financial considerations would affect their choice of specialty (p=.002) and practice location (p=.002). Male students were more likely to express a positive attitude toward private funding in the health care system, both with respect to increasing the amount of private funding (p=.007) and the addition of private paying patients (p=.002). CONCLUSION: Although women have almost reached equity with men in undergraduate medical education, female students are more likely than male students to have highly educated parents, suggesting that some barriers to access may still exist. The differences in attitudes of female and male medical students to finances and the public health care system become increasingly important as more women practice medicine. These sex differences need to be investigated further, as they could have implications for health policy.
