Understanding the impact of COVID-19 on antibiotic use in Canadian primary care: a matched-cohort study using EMR data.

BACKGROUND: Inappropriate or overuse of antibiotic prescribing in primary care highlights an opportunity for antimicrobial stewardship (AMS) programs aimed at reducing unnecessary use of antimicrobials through education, policies and practice audits that optimize antibiotic prescribing. Evidence from the early part of the pandemic indicates a high rate of prescribing of antibiotics for patients with COVID-19. It is crucial to surveil antibiotic prescribing by primary care providers from the start of the pandemic and into its endemic stage to understand the effects of the pandemic and better target effective AMS programs. METHODS: This was a matched pair population-based cohort study that used electronic medical record (EMR) data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN). Participants included all patients that visited their primary care provider and met the inclusion criteria for COVID-19, respiratory tract infection (RTI), or non-respiratory or influenza-like-illness (negative). Four outcomes were evaluated (a) receipt of an antibiotic prescription; (b) receipt of a non-antibiotic prescription; (c) a subsequent primary care visit (for any reason); and (d) a subsequent primary care visit with a bacterial infection diagnosis. Conditional logistic regression was used to evaluate the association between COVID-19 and each of the four outcomes. Each model was adjusted for location (rural or urban), material and social deprivation, smoking status, alcohol use, obesity, pregnancy, HIV, cancer and number of chronic conditions. RESULTS: The odds of a COVID-19 patient receiving an antibiotic within 30 days of their visit is much lower than for patients visiting for RTI or for a non-respiratory or influenza-like-illnesses (AOR = 0.08, 95% CI[0.07, 0.09] compared to RTI, and AOR = 0.43, 95% CI[0.38, 0.48] compared to negatives). It was found that a patient visit for COVID-19 was much less likely to have a subsequent visit for a bacterial infection at all time points. CONCLUSIONS: Encouragingly, COVID-19 patients were much less likely to receive an antibiotic prescription than patients with an RTI. However, this highlights an opportunity to leverage the education and attitude change brought about by the public health messaging during the COVID-19 pandemic (that antibiotics cannot treat a viral infection), to reduce the prescribing of antibiotics for other viral RTIs and improve antibiotic stewardship.

Perspectives on the representation of frailty in the electronic frailty index.

BACKGROUND: Frailty is a state of increased vulnerability from physical, social, and cognitive factors resulting in greater risk of negative health-related outcomes and increased healthcare expenditure. A 36-factor electronic frailty index (eFI) developed in the United Kingdom calculates frailty scores using electronic medical record data. There is currently no standardization of frailty screening in Canadian primary care. In order to implement the eFI in a Canadian context, adaptation of the tool is necessary because frailty is represented by different clinical terminologies in the UK and Canada. In considering the promise of implementing an eFI in British Columbia, Canada, we first looked at the content validation of the 36-factor eFI. Our research question was: Does the eFI represent frailty from the perspectives of primary care clinicians and older adults in British Columbia? METHODS: A modified Delphi using three rounds of questionnaires with a panel of 23 experts (five family physicians, five nurse practitioners, five nurses, four allied health professionals, four older adults) reviewed and provided feedback on the 36-factor eFI. These professional groups were chosen because they closely work as interprofessional teams within primary care settings with older adults. Older adults provide real life context and experiences. Questionnaires involved rating the importance of each frailty factor on a 0-10 scale and providing rationale for ratings. Panelists were also given the opportunity to suggest additional factors that ought to be included in the screening tool. Suggested factors were similarly rated in two Delphi rounds. RESULTS: Thirty-three of the 36 eFI factors achieved consensus (> 80% of panelists provided a rating of ≥ 8). Factors that did not achieve consensus were hypertension, thyroid disorder and peptic ulcer. These factors were perceived as easily treatable or manageable and/or not considered reflective of frailty on their own. Additional factors suggested by panelists that achieved consensus included: cancer, challenges to healthcare access, chronic pain, communication challenges, fecal incontinence, food insecurity, liver failure/cirrhosis, mental health challenges, medication noncompliance, poverty/financial difficulties, race/ethnic disparity, sedentary/low activity levels, and substance use/misuse. There was a 100% retention rate in each of the three Delphi rounds. CONCLUSIONS AND NEXT STEPS: Three key findings emerged from this study: the conceptualization of frailty varied across participants, identification of frailty in community/primary care remains challenging, and social determinants of health affect clinicians' assessments and perceptions of frailty status. This study will inform the next phase of a broader mixed-method sequential study to build a frailty screening tool that could ultimately become a standard of practice for frailty screening in Canadian primary care. Early detection of frailty can help tailor decision making, frame discussions about goals of care, prevent advancement on the frailty trajectory, and ultimately decrease health expenditures, leading to improved patient and system level outcomes.

Access to cancer clinical trials for racialised older adults: an equity-focused rapid scoping review protocol.

BACKGROUND: The intersection of race and older age compounds existing health disparities experienced by historically marginalised communities. Therefore, racialised older adults with cancer are more disadvantaged in their access to cancer clinical trials compared with age-matched counterparts. To determine what has already been published in this area, the rapid scoping review question are: what are the barriers, facilitators and potential solutions for enhancing access to cancer clinical trials among racialised older adults? METHODS: We will use a rapid scoping review methodology in which we follow the six-step framework of Arksey and O'Malley, including a systematic search of the literature with abstract and full-text screening to be conducted by two independent reviewers, data abstraction by one reviewer and verification by a second reviewer using an Excel data abstraction sheet. Articles focusing on persons aged 18 and over who identify as a racialised person with cancer, that describe therapies/therapeutic interventions/prevention/outcomes related to barriers, facilitators and solutions to enhancing access to and equity in cancer clinical trials will be eligible for inclusion in this rapid scoping review. ETHICS AND DISSEMINATION: All data will be extracted from published literature. Hence, ethical approval and patient informed consent are not required. The findings of the scoping review will be submitted for publication in a peer-reviewed journal and presentation at international conferences.

Prevalence and predictors of primary nonadherence to medications prescribed in primary care.

BACKGROUND: Most research on medication adherence has focused on secondary nonadherence and persistence to therapy. Medication prescriptions that are never filled by patients (primary nonadherence) remain understudied in the general population. METHODS: We linked prescribing data from primary care electronic medical records to comprehensive pharmacy dispensing claims between January 2013 and April 2019 in British Columbia (BC) to estimate primary nonadherence, defined as failure to dispense a new medication or its equivalent within 6 months of the prescription date. We used hierarchical multivariable logistic regression to determine prescriber, patient and medication factors associated with primary nonadherence among community-dwelling patients in primary care. RESULTS: Among 150 565 new prescriptions to 34 243 patients, 17% of prescriptions were never filled. Primary nonadherence was highest for drugs prescribed mostly on an as-needed basis, including topical corticosteroids (35.1%) and antihistamines (23.4%). In multivariable analysis, primary nonadherence was lower for prescriptions issued by male prescribers (odds ratio [OR] 0.66, 95% confidence interval [CI] 0.50-0.88). Primary nonadherence decreased with patient age (OR 0.91, 95% CI 0.90-0.92 for each additional 10 years) but increased with polypharmacy among patients aged 65 years or older. Patients filled more than 82% of their medication prescriptions within 2 weeks after their primary care provider visit. INTERPRETATION: The prevalence of primary nonadherence to new prescriptions was 17%. Interventions to address primary nonadherence could target older patients with multiple medication use and within the first 2 weeks of the prescription issue date.

Changes in comprehensiveness of services delivered by Canadian family physicians: Analysis of population-based linked data in 4 provinces.

OBJECTIVE: To describe changes in the comprehensiveness of services delivered by family physicians across service settings and service areas in 4 Canadian provinces, to identify which settings and areas have changed the most, and to compare the magnitude of changes by physician characteristics. DESIGN: Descriptive analysis of province-wide, population-based billing data linked to population and physician registries. SETTING: British Columbia, Manitoba, Ontario, and Nova Scotia. PARTICIPANTS: Family physicians registered to practise in the 1999-2000 and 2017-2018 fiscal years. MAIN OUTCOME MEASURES: Comprehensiveness was measured across 7 service settings (home care, long-term care, emergency departments, hospitals, obstetric care, surgical assistance, anesthesiology) and in 7 service areas consistent with office-based practice (prenatal and postnatal care, Papanicolaou testing, mental health, substance use, cancer care, minor surgery, palliative home visits). The proportion of physicians with activity in each setting and area are reported and the average number of service settings and areas by physician characteristics is described (years in practice, sex, urban or rural practice setting, and location of medical degree training). RESULTS: Declines in comprehensiveness were observed across all provinces studied. Declines were greater for comprehensiveness of settings than for areas consistent with office-based practice. Changes were observed across all physician characteristics. On average across provinces, declines in the number of service settings and service areas were highest among physicians in practice 20 years or longer, male physicians, and physicians practising in urban areas. CONCLUSION: Declining comprehensiveness was observed across all physician characteristics, pointing to changes in the practice and policy contexts in which all family physicians work.

Declining Comprehensiveness of Services Delivered by Canadian Family Physicians Is Not Driven by Early-Career Physicians.

We describe changes in the comprehensiveness of services delivered by family physicians in 4 Canadian provinces (British Columbia, Manitoba, Ontario, Nova Scotia) during the periods 1999-2000 and 2017-2018 and explore if changes differ by years in practice. We measured comprehensiveness using province-wide billing data across 7 settings (home, long-term care, emergency department, hospital, obstetrics, surgical assistance, anesthesiology) and 7 service areas (pre/postnatal care, Papanicolaou [Pap] testing, mental health, substance use, cancer care, minor surgery, palliative home visits). Comprehensiveness declined in all provinces, with greater changes in number of service settings than service areas. Decreases were no greater among new-to-practice physicians.

Essential Elements to Implementing a Paramedic Palliative Model of Care: An Application of the Consolidated Framework for Implementation Research.

Background: Comfort care without transport to hospital was not traditionally a paramedic practice. The novel Paramedics Providing Palliative Care at Home Program includes a new clinical practice guideline, medications, a database to manage and share goals of care, and palliative care training. This study determined essential elements for implementation, scale, and spread of this Program. Methods: Deliberative dialogs, a qualitative method, were held with diverse stakeholders/experts in one province with the Program (Nova Scotia, March 2018) and one without (British Columbia, July 2018). The Consolidated Framework for Implementation Research (CFIR) informed the discussion guide and was used in a framework analysis. Four team members analyzed the data independently; themes were derived by consensus with the broader research team. Results: CFIR constructs framed several key elements. Inter-sectoral communication is critical but challenged by privacy concerns and the siloed structure of the health system. Locally adapted training is an essential characteristic of the intervention; cost is a factor. A shift in mindset away from traditional paramedic roles is required; this can be facilitated by paramedic champions and a positive implementation climate. Early engagement of diverse stakeholders and planning for sustainability is key. Conclusion: This framework analysis using CFIR constructs can guide successful scale and spread of the program. The constructs of Outer setting: Cosmopolitanism; Characteristics of the intervention: Adaptability; Inner Setting: Implementation climate; and Processes: Engagement, and Planning, emerged as essential.

Control of Cardiovascular Risk Factors in Patients with Chronic Obstructive Pulmonary Disease.

Rationale: Cardiovascular disease accounts for one-third of deaths in patients with chronic obstructive pulmonary disease (COPD). Better control of cardiovascular risk factors in primary care could improve outcomes. Objectives: To define the prevalence, monitoring, treatment, and control of risk factors in patients with COPD. Methods: Repeated cross-sectional analysis of primary care electronic medical records for all patients with COPD in the Canadian Primary Care Sentinel Surveillance Network from 2013 to 2018 (n = 32,695 in 2018). A control group was matched 1:1 for age, sex, and rural residence (n = 32,638 in 2018). Five risk factors were defined using validated definitions including laboratory results: hypertension, dyslipidemia, diabetes, obesity, and smoking. Results: All risk factors were more common in patients with COPD compared with matched control subjects, including hypertension (52.3% vs. 44.9%), dyslipidemia (62.0% vs. 57.8%), diabetes (25.0% vs. 20.2%), obesity (40.8% vs. 36.8%), and smoking (40.9% vs. 11.4%), respectively. The mean Framingham risk score was 20.6% versus 18.6%, with 53.8% of patients with COPD being high risk (⩾20%). Monitoring of risk factors within the last year in patients with COPD in 2018 was suboptimal: 71.8% hypertension, 39.4% dyslipidemia, 74.5% diabetes, 52.3% obesity. Smoking status was infrequently recorded in the electronic record. In those monitored, guideline recommended targets were achieved in 60.8%, 46.6%, 57.4%, 10.6% and 12.0% for each risk factor. Cardiovascular therapies including angiotensin-converting enzyme inhibitors (69%), statins (69%), and smoking cessation therapies (27%) were underused. Conclusions: In patients with COPD, major cardiovascular risk factors are common, yet inadequately monitored, undertreated, and poorly controlled. Strategies are needed to improve comprehensive risk factor management proven to reduce cardiovascular morbidity and mortality.

One year follow-up and exploratory analysis of a patient-centered interdisciplinary care intervention for multimorbidity.

CONTEXT: Interventions for people with multimorbidity have obtained mixed results. We aimed to document the long-term effect of an intervention for people with multimorbidity. METHODS: 284 patients (18-80 years) presenting three or more chronic conditions were recruited from seven family medicine groups in the Saguenay-Lac St-Jean region, Quebec, Canada. The patient-centered intervention was based on motivational approach and self-management support. Outcomes were evaluated in a one-year pre-post study design with questionnaires that included the Health Education Questionnaire (heiQ), the Self-Efficacy for Managing Chronic Diseases, the Veteran RAND-12 Health Survey (VR-12), the EuroQoL 5-Domains questionnaire, the Kessler six item Psychological Stress Scale, and measures of smoking habit, physical activity, healthy eating and alcohol consumption. Subgroup analyses by age, number of conditions, sex, and income were also conducted. RESULTS: The heiQ domain of emotional wellbeing improved significantly. Improvement was also observed for the VR-12 and the K6. Among the health behaviours, only healthy eating was improved. Subgroup analyses in this exploratory study suggest that younger patients, those with lower number of chronic conditions or higher incomes may respond better in relation to self-management, health status and health behaviours. CONCLUSION: One year after the intervention, participants significantly improved a variety of outcomes. Subgroup analyses suggest that younger patients, those with lower number of chronic conditions or higher incomes may respond better in relation to self-management, health status and health behaviours. This suggests that future interventions should be tailored to patients' characteristics including age, sex, income and number of conditions.

Priority measures for publicly reporting primary care performance: Results of public engagement through deliberative dialogues in 3 Canadian provinces.

OBJECTIVE: While public reporting of hospital-based performance measurement is commonplace, it has lagged in the primary care sector, especially in Canada. Despite the increasing recognition of patients as active partners in the health-care system, little is known about what information about primary care performance is relevant to the Canadian public. We explored patient perspectives and priorities for the public reporting of primary care performance measures. METHODS: We conducted six deliberative dialogue sessions across three Canadian provinces (British Columbia, Ontario, Nova Scotia). Participants were asked to rank and discuss the importance of collecting and reporting on specific dimensions and indicators of primary care performance. We conducted a thematic analysis of the data. RESULTS: Fifty-six patients participated in the dialogue sessions. Measures of access to primary care providers, communication with providers and continuity of information across all providers involved in a patient's care were identified as the highest priority indicators of primary care performance from a patient perspective. Several common measures of quality of care, such as rates of cancer screening, were viewed as too patient dependent to be used to evaluate the health system or primary care provider's performance. CONCLUSIONS: Our findings suggest that public reporting aimed at patient audiences should focus on a nuanced measure of access, incorporation of context reported alongside measurement that is for public audiences, clear reporting on provider communication and a measure of information continuity. Participants highlighted the importance the public places on their providers staying up to date with advances in care.

Developmental regulation of lifelong dental experiences and beliefs in Guangzhou and Hong Kong.

AIMS: The aim of this study was to explain through the life-course and life-span perspectives of developmental regulation theory the controls on dental experiences and beliefs throughout the lives of older people in Guangzhou and Hong Kong. BACKGROUND: Dental diseases and disabilities among older people are serious public health concerns in China. METHODS: A facilitator conducted eight focus groups, three in Hong Kong and five in Guangzhou, involving a total of 51 participants. She encouraged discussions about lifetime events to explain dental experiences and beliefs. Transcripts were coded and analysed using a constant comparative approach to identify themes that explained the regulators of dental experiences throughout the participants' lives. RESULTS: Participants explained the influence of culture and history through critical events, and how external and internal factors regulated their current oral health status and beliefs. They emphasised the role of Traditional Chinese Medicine and family, and the stress of social upheaval compounded by a scarcity of dental services. They revealed also how current choice of dental services and health promotional programs, helped by personal food choice, self-reliance, and scepticism, helped them to adjust and cope with dental diseases and disabilities and the commercialisation of dental services. CONCLUSIONS: Dental experiences and beliefs of older people living in Guangzhou and Hong Kong were regulated strongly during personal development by culture and history during critical events, and by various controlling factors, such as health promotion and choice of services supplemented by food choice, nutritional balance, self-reliance, scepticism and social adjustments.

Associations between polypharmacy and treatment intensity for hypertension and diabetes: a cross-sectional study of nursing home patients in British Columbia, Canada.

OBJECTIVES: Describe nursing home polypharmacy prevalence in the context of prescribing for diabetes and hypertension and determine possible associations between lower surrogate markers for treated hypertension and diabetes (overtreatment) and polypharmacy. DESIGN: Cross-sectional study. SETTING: 6 nursing homes in British Columbia, Canada. PARTICIPANTS: 214 patients residing in one of the selected facilities during data collection period. PRIMARY AND SECONDARY OUTCOME MEASURES: Polypharmacy was defined as ≥9 regular medications. Overtreatment of diabetes was defined as being prescribed at least one hypoglycaemic medication and a glycosylated haemoglobin (HbA1c) ≤7.5%. Overtreatment of hypertension required being prescribed at least one hypertension medication and having a systolic blood pressure ≤128 mm Hg. Polypharmacy prescribing, independent of overtreatment, was calculated by subtracting condition-specific medications from total medications prescribed. RESULTS: Data gathering was completed for 214 patients, 104 (48%) of whom were prescribed ≥9 medications. All patients were very frail. Patients with polypharmacy were more likely to have a diagnosis of hypertension (p=0.04) or congestive heart failure (p=0.003) and less likely to have a diagnosis of dementia (p=0.03). Patients with overtreated hypertension were more likely to also experience polypharmacy (Relative Risk (RR))1.77 (1.07 to 2.96), p=0.027). Patients with overtreated diabetes were prescribed more non-diabetic medications than those with a higher HbA1c (11.0±3.7vs 7.2±3.1, p=0.01). CONCLUSION: Overtreated diabetes and hypertension appear to be prevalent in nursing home patients, and the presence of polypharmacy is associated with more aggressive treatment of these risk factors. The present study was limited by its small sample size and cross-sectional design. Further study of interventions designed to reduce overtreatment of hypertension and diabetes is needed to fully understand the potential links between polypharmacy and potential of harms of condition-specific overtreatment.

The relationship between language proficiency and surgical length of stay following cardiac bypass surgery.

BACKGROUND: Anglophone nurses face the challenge of communicating health information to patients who do not speak or understand English. Limited English-proficient patients are at higher risk of misinterpreting health information teaching. Successful recovery after coronary artery bypass graft surgery requires patients' engagement with healthcare professionals and active participation in therapies and related undertakings. Determination of whether limited English-proficient patients undergoing coronary artery bypass graft surgery recover at the same pace as the general population is of interest. AIM: This study examined whether limited English-proficient patients had prolonged post-operative length of stay following coronary artery bypass graft surgery. The patients' length of stay with regard to a clinical pathway target was also examined. METHOD: A retrospective medical record review of all patients undergoing isolated coronary artery bypass graft surgery in a 2-year period was conducted. A screening tool was developed to identify limited English-proficient patients through examination of their medical records. RESULTS: A total of 691 of 712 (97.1%) patients met the inclusion criteria; 103 (14.9%) patients were identified as limited English-proficient. The post-operative median length of stay of limited English-proficient patients was 7 days compared with 6 days for the English-proficient patients (p = 0.007). Limited English-proficient patients had higher infection rates (29.1%) vs. English-proficient patients (16.7%) (odds ratio = 2.05 (95% confidence intervals 1.27-3.30)). Post-operative infection was the strongest predictor of length of stay and fully mediated the relationship between language proficiency and length of stay. CONCLUSION: When compared with English-proficient patients, limited English-proficient patients had greater infection rates, which were associated with longer length of stay. These findings warrant examination of the mechanisms through which post-operative infections are acquired by limited English-proficient patients.

The diagnosis of depression and its treatment in Canadian primary care practices: an epidemiological study.

BACKGROUND: A diagnosis of depression is common in primary care practices, but data are lacking on the prevalence in Canadian practices. We describe the prevalence of the diagnosis among men and women, patient characteristics and drug treatment in patients diagnosed with depression in the primary care setting in Canada. METHODS: Using electronic medical record data from the Canadian Primary Care Sentinel Surveillance Network, we examined whether the prevalence of a depression diagnosis varied by patient characteristics, the number of chronic conditions and the presence of the following chronic conditions: hypertension, diabetes, chronic obstructive pulmonary disease, osteoarthritis, dementia, epilepsy and parkinsonism. We used regression models to examine whether patient characteristics and type of comorbidity were associated with a depression diagnosis. RESULTS: Of the 304 412 patients who had at least 1 encounter with their primary care provider between Jan. 1, 2011, and Dec. 31, 2012, 14% had a diagnosis of depression. Current or past smokers and women with a high body mass index had higher rates of depression. One in 4 patients with a diagnosis of depression also had another chronic condition; those with depression had 1.5 times more primary care visits. About 85% of patients with depression were prescribed medication, most frequently selective serotonin reuptake inhibitors, followed by atypical antipsychotics. INTERPRETATION: Our data provide information on the prevalence of a depression diagnosis in primary care and associations with being female, having a chronic condition, smoking history and obesity in women. Our findings may inform research and assist primary care providers with early detection and interventions in at-risk patient populations.

Colorectal cancer screening: what do women from diverse ethnic groups want?

BACKGROUND: Little is known about factors associated with willingness to undergo colorectal cancer (CRC) screening for personal or public health benefit among women from diverse race/ethnic groups. OBJECTIVE: To evaluate factors associated with willingness to undergo CRC screening for personal and public health benefit among women from diverse race/ethnic groups. METHODS: We interviewed women aged 50 to 80 from four racial/ethnic groups from primary care clinics in 2003-2005. We asked about demographics, CRC screening knowledge and history, perceived risk of colon cancer, and about the outcomes of intention to be screened for personal benefit and for public health benefit. RESULTS: Of the 492 women who completed the interview, 32 % were White, 16 % were African American, 21 % were Latina and 32 % were Asian. Up-to-date screening was reported by 77 % of women, with similar numbers obtaining fecal occult blood test (FOBT) within 2 years or colonoscopy within 10 years. The majority of women were "likely or very likely" to get FOBT or colonoscopy after learning the benefits and risks. Multivariate models showed that compared to Whites, fewer Asians would undergo colonoscopy (OR = 0.28; 95 % CI: 0.12, 0.63), while more Latinas would undergo colonoscopy (OR = 6.14; 95 % CI: 1.77, 21.34) and obtain regular CRC screening (OR = 4.47; 95 % CI: 1.66, 12.04). The majority would obtain CRC screening even if they would not personally benefit; those who perceived themselves to be at higher than average cancer risk were more likely to participate in CRC screening for public health benefit (OR = 2.32; 95 % CI: 1.32, 4.09). CONCLUSIONS: The majority of women are willing to undergo screening for personal benefit. Asians were less likely, and Latinas more likely, to accept colonoscopy. Most are also willing to undergo screening for public health benefit. Self-perceived risk of CRC was the most consistent predictor of willingness and intention to be screened for either personal or public health benefit.

Willingness to use tamoxifen to prevent breast cancer among diverse women.

Use of chemoprevention to prevent development of breast cancer among high-risk women has been limited despite clinical evidence of its benefit. Our goals were to determine whether knowledge of the benefits and risks of tamoxifen affects a woman's willingness to take it to prevent breast cancer, to define factors associated with willingness to take tamoxifen, and to evaluate race/ethnic differences. Women, ages 50-80, who identified as African American, Asian, Latina, or White, and who had at least one visit to a primary care physician in the previous 2 years, were recruited from ambulatory practices. After a screening telephone survey, women completed an in-person interview in their preferred language. Multivariate regression models were constructed to examine the associations of demographic characteristics, numeracy, breast cancer history, and health knowledge with willingness to take tamoxifen. Over 40% of the women reported they would likely take tamoxifen if determined to be at high risk, and 31% would be somewhat likely to do so. Asian women, those with no insurance, and those with less than high school education were significantly more likely to be willing to take tamoxifen. Higher scores on numeracy and on breast cancer knowledge were also associated with willingness to take tamoxifen. A higher tamoxifen knowledge score was inversely related to willingness to take the drug. Factors affecting women's willingness to take breast cancer chemoprevention drugs vary and are not determined solely by knowledge of risk/benefit or risk perception.

Using visual displays to communicate risk of cancer to women from diverse race/ethnic backgrounds.

OBJECTIVE: This study evaluated how well women from diverse race/ethnic groups were able to take a quantitative cancer risk statistic verbally provided to them and report it in a visual format. METHODS: Cross-sectional survey was administered in English, Spanish or Chinese, to women aged 50-80 (n=1160), recruited from primary care practices. The survey contained breast, colorectal or cervical cancer questions regarding screening and prevention. Women were told cancer-specific lifetime risk then shown a visual display of risk and asked to indicate the specific lifetime risk. Correct indication of risk was the main outcome. RESULTS: Correct responses on icon arrays were 46% for breast, 55% for colon, and 44% for cervical; only 25% correctly responded to a magnifying glass graphic. Compared to Whites, African American and Latina women were significantly less likely to use the icon arrays correctly. Higher education and higher numeracy were associated with correct responses. Lower education was associated with lower numeracy. CONCLUSIONS: Race/ethnic differences were associated with women's ability to take a quantitative cancer risk statistic verbally provided to them and report it in a visual format. PRACTICE IMPLICATIONS: Systematically considering the complexity of intersecting factors such as race/ethnicity, educational level, poverty, and numeracy in most health communications is needed.

Canadian Punjabi Sikh men's experiences of lifestyle changes following myocardial infarction: cultural connections.

OBJECTIVE: To describe how culture underlies Canadian Punjabi Sikh men's experiences of adopting lifestyle changes following myocardial infarction (MI). DESIGN: Qualitative, interpretive design. In-depth, individual interviews were conducted with 27 Canadian Punjabi Sikh men post-MI. Data were analysed using constant comparative methods. RESULTS: Cultural influences were identified in Punjabi Sikh men's descriptions of their experience of adopting lifestyle changes. Actions related to self-care, rehabilitation and lifestyle change post-MI were embedded in collectivist family and community contexts. Three themes, derived from the data, were found to intertwine with these contexts; they related to food consumption, physical exercise and faith and religion. CONCLUSION AND IMPLICATIONS: These findings highlight how collectivist ideals influence Canadian Punjabi Sikh men's adoption of lifestyle changes post-MI. The content and processes by which healthcare providers deliver heart health and rehabilitation to Canadian Punjabi Sikh men might be guided, at least in part, by the collectivist cultural practices underpinning our findings.

Developing and sustaining leadership in public health nursing: findings from one British Columbia health authority.

OBJECTIVE: To develop clinical leadership among front-line public health nurses (PHNs). METHODS: This paper describes a quality improvement process to develop clinical leadership among front-line PHNs. Three activities were undertaken by a working group consisting mainly of front-line staff: engaging PHNs in an online change-readiness questionnaire, administering a survey to clients who had ever used public health services delivered by one Vancouver Community Infant, Child and Youth (ICY) program team and conducting three group interviews with public health providers. The group interviews asked about PHN practice. They were analyzed using thematic content analysis. RESULTS: This quality improvement project suggests that PHNs (n=70) strongly believed in opportunities for system improvement. Client surveys (n=429) and community partner surveys (n=79) revealed the importance of the PHN role. Group interview data yielded three themes: PHNs were the "hub" of community care; PHNs lacked a common language to describe their work; PHNs envisioned their future practice encompassing their full scope of competencies. PHNs developed the "ICY Public Health Nursing Model," which articulates 14 public health interventions and identifies the scope of their work. CONCLUSION: Developing and sustaining clinical leadership in front-line PHNs was accomplished through these various quality assurance activities.

Registration for public drug benefits across areas of differing ethnic composition in British Columbia, Canada.

BACKGROUND: In 2003, the government of British Columbia, Canada introduced a universal drug benefit plan to cover drug costs that are high relative to household income. Residents were required to register in order to be eligible for the income-based benefits. Given past research suggesting that registration processes may pose an access barrier to certain subpopulations, we aimed to determine whether registration rates varied across small geographic areas that differed in ethnic composition. METHODS: Using linked population-based administrative databases and census data, we conducted multivariate logistic regression analyses to determine whether the probability of registration for the public drug plan varied across areas of differing ethnic composition, controlling for household-level predisposing, enabling and needs factors. RESULTS: The adjusted odds of registration did not differ across regions characterized by high concentrations (greater than 30%) of residents identifying as North American, British, French or other European. Households located in areas with concentrations of residents identifying as an Asian ethnicity had the highest odds of program registration: Chinese (OR = 1.21, CI: 1.19-1.23) and South Asian (OR = 1.19, CI: 1.16-1.22). Despite this positive finding, households residing in areas with relatively high concentrations of recent immigrants had slightly lower adjusted odds of registering for the program (OR = 0.97, CI: 0.95-0.98). CONCLUSIONS: This study identified ethnic variation in registration for a new public drug benefit program in British Columbia. However, unlike previous studies, the variation observed did not indicate that areas with high concentrations of certain ethnicities experienced disadvantages. Potential explanations are discussed.
