Primary care physician characteristics associated with cancer screening: a retrospective cohort study in Ontario, Canada

Important and Feasible Actions to Address Cervical Screening Participation amongst South Asian Women in Ontario: A Concept Mapping Study with Service Users and Service Providers

Regular cervical screening can largely prevent the development of cervical cancer and innovative methods are needed to better engage people in screening. In Ontario, Canada, South Asian women have some of the lowest rates of screening in the province. In this study, we used concept mapping to engage two stakeholder groups-South Asian service users and service providers-to identify and prioritize points of intervention to encourage the uptake of cervical screening. After participants brainstormed a master list of statements, 45 participants rated the statements based off 'importance' and 'ease to address' in relation to encouraging cervical screening. A bivariate plot (X-Y graph) that shows the average rating values for each statement across the two rating variables (a 'go-zone' display) was produced to display priorities for implementation. Statements that were considered high priority to address reflected issues around education and awareness including understanding and communication related to cervical screening and preventative care, as well as the need for trusted sources of information. Statements that were considered high priority but challenging to implement were centered around fear, stigma, discomfort, family and personal priorities. This study highlighted that stigma, norms and social relations that impact the uptake of screening must be addressed in order for education and awareness raising to be effective and to move people from conviction around screening to action.

Implementation of a Cervical Cancer Screening Intervention for Under- or Never-Screened Women in Ontario, Canada: Understanding the Acceptability of HPV Self-Sampling

With appropriate screening, cervical cancer can be prevented. In Ontario, Canada, some groups of women have low screening rates. South Asian, Middle Eastern and North African women are particularly at risk of under-screening. Currently, cytology-based screening is used in Ontario, although the growing evidence and adoption of HPV testing for cervical screening has encouraged many jurisdictions around the world to move towards HPV testing, with the option of self-sampling. We conducted an intervention beginning in June 2018, where we recruited over 100 under- or never-screened (UNS) women who identify as South or West Asian, Middle Eastern or North African from the Greater Toronto Area, to understand the uptake and acceptability of HPV self-sampling as an alternative to a Pap test. Participants self-selected if they tried the kit or not and completed both quantitative and qualitative research activities. This paper focuses on the qualitative arm of the study, where follow-ups and five focus groups were conducted with those who tried the kit (three groups) and those who did not (two groups), as well as eight key informant interviews with community champions and others who were involved in our recruitment. We used the Consolidated Framework for Implementation Research (CFIR) to guide our data collection and analysis. Major themes around convenience, privacy and comfort came from the data as important drivers of the uptake of the intervention. The role of community champions and peers in engaging and educating UNS women, as well as having self-confidence to collect the sample, also came out as factors impacting uptake and plans for continued use. Overall, the intervention showed that HPV self-sampling is an acceptable alternative to a Pap test for some but not all UNS women in Ontario.

Barriers and Facilitators to Colorectal Cancer Screening in South Asian Immigrants: A Systematic Review

OBJECTIVE

The purpose of this systematic review is to broaden our knowledge of colorectal cancer (CRC) screening in South Asian immigrants living in Canada, Hong Kong, the United Kingdom, the United States, and Australia by determining the barriers and facilitators and examining interventions for CRC screening.

METHODS

A literature search of PubMed, Ovid Medline, and Google was conducted using South Asian, Asian Indians, cancer screening, colorectal neoplasm, early detection of cancer, and mass screening as search terms. The review was conducted following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Only research articles written in English from 2000 to July 2022 were collected. Inclusion criteria included all English-language articles, the South Asian population, and either reporting barriers, facilitators, interventions, or recommendations for CRC screening. Exclusion criteria included all articles that did not meet inclusion criteria or were duplicates. A total of 32 articles were deemed eligible for inclusion and were retrieved for further analysis. The countries of origin in the articles reviewed included Canada, Hong Kong, the United Kingdom, the United States, and Australia.

RESULTS

In general, the studies indicated that South Asians have low CRC screening rates. The most common barriers reported were poor knowledge/awareness of CRC and CRC screening, lack of physician recommendation, psychological factors (e.g., fear, anxiety, and shame), cultural/religious factors, and sociodemographic factors (language barrier, lower income, and female gender). The most important facilitator reported was the physician's recommendation. Six intervention studies of either education or organized screening programs were shown to have a positive influence by increasing knowledge and improving attitudes toward CRC screening.

CONCLUSION

Of the limited number of studies identified, the population categorized as South Asians was largely heterogeneous, including a diversity of ethnicities. Although the rates of CRC among South Asians were relatively low, there remain many cultural barriers to the awareness of and screening for CRC in this population. Further research in this population is needed to better identify the factors related to CRC in individuals of South Asian ethnicity. Recommending CRC screening by physicians and mid-level providers and educating patients with culturally sensitive programs and materials are important to increase knowledge and awareness of CRC and CRC screening.

Reach and effectiveness of an HPV self-sampling intervention for cervical screening amongst under- or never-screened women in Toronto, Ontario Canada

BACKGROUND

Cervical cancer is almost entirely preventable with appropriate and timely screening. In Ontario, Canada, South Asian, Middle Eastern and North African women have some of the lowest rates of screening and a suggested higher burden of cervical cancer. With increasing international evidence and adoption of HPV testing, many screening programs are making the move away from Pap tests and towards HPV testing with the option of HPV self-sampling seeming promising for under- or never-screened (UNS) women. Our study aimed to understand the uptake and acceptability of an HPV self-sampling intervention amongst these disproportionately UNS women in Peel region and surrounding areas in Ontario.

METHODS

A community -based mixed methods approach guided by the RE-AIM framework was used to recruit approximately 100 UNS racialized immigrant women aged 30-69, during the period of June 2018 to December 2019. The main recruitment strategy included community champions (i.e. trusted female members of communities) to engage people in our selected areas in Peel Region. Participants completed a study questionnaire about their knowledge, attitudes and practices around cervical cancer screening, self-selected whether to use the HPV self-sampling device and completed follow-up questions either about their experience with self-sampling or going to get a Pap test.

RESULTS

In total, 108 women participated in the study, with 69 opting to do self-sampling and 39 not. The majority of women followed through and used the device (n = 61) and found it 'user friendly.' The experience of some participants suggests that clearer instructions and/or more support once at home is needed. Survey and follow-up data suggest that privacy and comfort are common barriers for UNS women, and that self-sampling begins to address these concerns. Across both groups addressing misinformation and misconceptions is needed to convince some UNS women to be screened. Family, friends and peers also seemed to play a role in the decision-making process.

CONCLUSIONS

HPV self-sampling is viewed as an acceptable alternative to a Pap test for cervical screening, by some but not all UNS women. This method begins to address some of the barriers that often prevent women from being screened and is already being offered in some jurisdictions as an alternative to clinical cervical cancer screening.

General practitioner gender and use of diagnostic procedures: a French cross-sectional study in training practices

OBJECTIVES

The acceleration in the number of female doctors has led to questions about differences in how men and women practice medicine. The aim of this study was to assess the influence of general practitioner (GP) gender on the use of the three main categories of diagnostic procedures-clinical examinations, laboratory tests and imaging investigations.

DESIGN

Cross-sectional nationwide multicentre study.

SETTING

French training general practices.

PARTICIPANTS

The patient sample included all the voluntary patients over a cumulative period of 5 days per office between November 2011 and April 2012. The GP sample included 85 males and 43 females.

METHODS

54 interns in general practice, observing their GP supervisors, collected data about the characteristics of GPs and consultations, as well as the health problems managed during the visit and the processes of care associated with them. Using hierarchical multilevel mixed-effect logistic regression models, we performed multivariable analyses to assess differences in each of the three main categories of diagnostic procedures, and two specific multivariable analyses for each category, distinguishing screening from diagnostic or follow-up procedures. We searched for interactions between GP gender and patient gender or type of health problem managed.

RESULTS

This analysis of 45 582 health problems managed in 20 613 consultations showed that female GPs performed more clinical examinations than male GPs, both for screening (OR 1.75; 95% CI 1.19 to 2.58) and for diagnostic or follow-up purposes (OR 1.41; 95% CI 1.08 to 1.84). Female GPs also ordered laboratory tests for diagnostic or follow-up purposes more frequently (OR 1.21; 95% CI 1.03 to 1.43). Female GPs performed even more clinical examinations than male GPs to diagnose or follow-up injuries (OR 1.69; 95% CI 1.19 to 2.40).

CONCLUSION

Further research on the appropriateness of diagnostic procedures is required to determine to what extent these differences are related to underuse or overuse.

Physicians' characteristics and practices associated with the provision of cancer screening advice to their patients: the Spanish SUN cohort study

OBJECTIVES

To evaluate the association between cancer screening counselling provided by medical doctors to their patients and each doctor's own anthropometrics, lifestyle, cancer screening practices, and personal and family history of cancer.

DESIGN

Prospective cohort study.

SETTING

Substudy including physicians participating in a Spanish cohort study with open enrolment.

PARTICIPANTS

Among 22 800 participants in the cohort as of May 2018, there were 2371 physicians who had replied to the cohort baseline questionnaire, had an email account and were younger than 65 years (retirement age in Spain). From this subsample, 890 replied to an online questionnaire focused on their clinical practices related to the counselling provided to their patients and to their prescription practices of preventive medications. Their mean age was 51.7 (SD 9.4) years and 48% were women.

OUTCOME MEASURES

Frequency of counselling given to their patients on specific practices of breast, colorectal and prostate cancer screenings.

RESULTS

Counselling on cancer screening to their patients was provided by 65% of physicians in a scenario of colorectal cancer, 59% for prostate cancer and 58% for breast cancer. More frequent cancer screening counselling was associated with the specialties of family medicine (OR=9.4, 95% CI 5.1 to 17.1) and internal medicine (OR=2.9, 95% CI 1.5 to 5.7) as compared with other specialties. Recommending cancer screening was associated with more frequent counselling on smoking cessation (OR=3.7, 95% CI 2.6 to 5.4), having personally attended colorectal cancer screening (OR=2.2, 95% CI 1.1 to 4.7) and prescribing blood pressure medication more often than their colleagues (OR=2.1, 95% CI 1.2 to 3.7).

CONCLUSIONS

Among medical doctors, cancer screening counselling was provided to their patients more frequently for doctors with family medicine or internal medicine specialties and for physicians who regularly offered counselling on certain lifestyle behaviours, and those having personally attended colorectal cancer screening. Doctors' own personal practices and knowledge of healthy lifestyles may help doctors to more frequently provide counselling on cancer screening to their patients.

Care in the Community: Opportunities to improve cancer screening uptake for people living with low income

Despite organized provincial cancer screening programs, people living with low income consistently have lower rates of screening in Ontario, Canada than their more socioeconomically advantaged peers. We previously published results of a two-phase, exploratory qualitative study involving both interviews and focus groups whose objective was to integrate knowledge of people living with low income on how to improve primary care strategies aimed at increasing cancer screening uptake. In the current paper, we report previously unpublished findings from that study that identify how taking a community outreach approach in primary care may lead to increased cancer screening uptake among people living with low income. Participants told us that they saw value in a community outreach approach to cancer screening. They recommended specific actionable approaches, in particular, mobile community-based screening and community information sessions, and recommended taking an ethno-specific lens depending on the communities being targeted. Participants expressed a desire for primary care providers to go out into the community to learn more about the whole patient, such as could be achieved with home visits, but they simultaneously believed that this may be challenging in urban settings and in the context of perceived physician shortages. Models of primary care that provide support to an entire local community and provide some of their services directly in that community may have a meaningful impact on cancer screening for socially marginalized groups.

Stage of colorectal cancer diagnosis for immigrants: a population-based retrospective cohort study in Ontario, Canada

BACKGROUND

Colorectal cancer (CRC) is the second most common cause of cancer death in Canada. Immigrants in Ontario, Canada's most populous province, are known to have lower rates of CRC screening, but differences in stage of CRC diagnosis are not known.

METHODS

We utilized linked administrative databases to compare early (stage I-II) versus late (stage III-IV) stage of CRC diagnosis for immigrants versus long-term residents among patients diagnosed in Ontario between 2012 and 2017 (n = 37,717) and examined the association of immigration-related, sociodemographic, and healthcare-related factors with stage.

RESULTS

Almost 45% of those with CRC were diagnosed at a late stage. Immigrants were slightly more likely to be diagnosed at a late stage than their long-term resident counterparts [Adjusted relative risks (ARRs) 1.06 (95% CI 1.02-1.10)], but after adjusting for age and sex, this difference was no longer significant. In fully adjusted models, we observed a higher likelihood of late-stage diagnosis for people with the fewest co-morbidities (ARR 0.86 [95% CI 0.83-0.89]) and those with no visits to primary care (versus a high level of continuity of care) [ARR 1.07 (95% CI 1.03-1.12)].

CONCLUSION

Immigrants were not more likely to have a late-stage CRC diagnosis after adjusting for relevant factors, but access to primary care and healthcare contact was significantly associated with diagnostic stage.

IMPACT

Attachment to a primary care provider who provides regular preventive care may play a role in more favorable stage at diagnosis for CRC and thus should be a healthcare system priority.

Contextual factors associated with cancer screening uptake: A systematic review of observational studies

We conducted a systematic review of a wide range of contextual factors related to cancer screening uptake that have been studied so far. Studies were identified through PubMed and Web of Science databases. An operational definition of context was proposed, considering as contextual factors: social relations directly aimed at cancer screening, health care provider and facility characteristics, geographical/accessibility measures and aggregated measures at supra-individual level. We included 70 publications on breast, cervical and/or colorectal cancer screening from 42 countries, covering a data period of 24 years. A wide diversity of factors has been investigated in the literature so far. While several of them, as well as many interactions, were robustly associated with screening uptake (family, friends or provider recommendation, provider sex and experience, area-based socio-economic status…), others showed less consistency (ethnicity, urbanicity, travel time, healthcare density …). Screening inequities were not fully explained through adjustment for individual and contextual factors. Context, in its diversity, influences individual screening uptake and lots of contextual inequities in screening are commonly shared worldwide. However, there is a lack of frameworks, standards and definitions that are needed to better understand what context is, how it could modify individual behaviour and the ways of measuring and modifying it.

Understanding the Acceptability and Uptake of HPV Self-Sampling Amongst Women Under- or Never-Screened for Cervical Cancer in Toronto (Ontario, Canada): An Intervention Study Protocol

Cervical cancer remains a global public health concern, even though scientific advancements have made the disease almost entirely preventable. With the link between human papillomavirus (HPV) and cervical cancer, and the subsequent improvement in screening technology, there is potential to improve access and coverage of cervical screening with the introduction of HPV self-sampling. In Ontario, Canada, a province with a cytology-based screening program (i.e., Pap test), women who identify as South Asian, West Asian, Middle Eastern and North African have some of the lowest rates of screening, and research suggests they have a higher burden of cervical cancer. In this study, we will use both quantitative and qualitative methods to understand the acceptability and uptake of a take-home HPV self-sampling kit. Working with community champions—people with pre-existing connections with local groups—we will recruit women from these groups who are under- or never-screened for cervical cancer. Women will self-select whether they are in the group that tries HPV self-sampling or in the group that does not. We will aim for 100 women in each group. All participants will provide feedback on the feasibility, acceptability and preferences for cervical screening through a survey and phone follow-up. Women who self-select the HPV self-sampling group, will be followed up to find out if they followed through with self-sampling and to understand their experience using the device. Women who do not want to try self-sampling will be followed up to see if they went on to get a Pap test. The qualitative phase of this study consists of five focus groups with participants and semi-structured interviews with key informants in the community.

Cervical Cancer Screening Among Immigrant Women Residing in Australia: A Systematic Review

Since the introduction of systematic population-based cervical cancer screening in Australia in 1991, age-standardized incidence of cervical cancer has halved. Given recent advances in human papillomavirus (HPV) vaccination and screening, cervical cancer may be eliminated nationally within 20 years. However, immigrant women are not equitably reached by screening efforts. This study systematically reviewed evidence on cervical cancer screening practices among immigrant women in Australia. A systematic search of MEDLINE, Embase, PubMed, CINAHL, and PsycINFO and gray literature for English language studies published till March 1, 2019, was conducted. Observational and qualitative studies evaluating cervical cancer screening awareness and participation of immigrant women were screened. Of 125 potentially relevant studies, 25 were eligible: 16 quantitative (4 cohort, 12 cross-sectional), 6 qualitative, and 3 mixed-methods studies. Quantitative studies indicated 1% to 16% lower screening rates among migrant women compared with Australian-born women, with participation of South Asian women being significantly lower (odds ratio = 0.54, 95% confidence interval = 0.48-0.61). Qualitative studies illustrated factors affecting women's willingness to participate in screening, including insufficient knowledge, low-risk perception, and unavailability of a female health professionals being key barriers. Future studies should focus on South Asian women, due to recent increase in their immigration.

Out of reach? Correlates of cervical cancer underscreening in women with varying levels of healthcare interactions in a United States integrated delivery system

One in five U.S. women with health insurance are underscreened for cervical cancer. We sought to identify whether underscreening correlates differed among women with different levels of health care interaction. Among women age 30-64 years who were members of an integrated U.S. health system, we used 2014-2015 electronic health record data to identify underscreened cases (≥3.4 years since last Papanicolaou (Pap) test, n=3352) and screening-adherent controls (<3.4 years since last Pap test, n=45,359) and extracted data on potential underscreening correlates (demographics, health history, and healthcare utilization). We calculated the odds of underscreening in the total population and by subgroups defined by healthcare visits and online health portal usage in the prior 12 months. Underscreening was associated with older age (50-64 vs. 30-39; odds ratio (OR)=1.6; 95%CI=1.4-1.8), current tobacco use (vs. never use; OR=2.1; 95%CI=1.8-2.2), higher BMI (≥35 kg/m² vs <25 kg/m², OR=2.0; 95%CI=1.8-2.3), screening non-adherence for colorectal cancer (OR=5.1; 95%CI=4.6-5.7) and breast cancer (OR=8.1, 95%CI=7.2-9.0), and having no recent visit with their primary care provider (PCP) nor recent health portal use (vs. recent PCP visit and portal use; OR=8.4, 95%CI=7.6-9.4). Underscreening correlates were similar between the total study population and within all healthcare interaction groups. Interaction with the healthcare system is associated with lower odds of underscreening, but sociodemographic and health status correlates are similar regardless of primary care visits or online portal use. These data support the need for additional interventions to reach insured women who remain underscreened for cervical cancer.

Perspectives of family physicians towards access to lung cancer screening for individuals living with low income - a qualitative study

BACKGROUND

Individuals living with low income are less likely to participate in lung cancer screening (LCS) with low-dose computed tomography. Family physicians (FPs) are typically responsible for referring eligible patients to LCS; therefore, we sought to understand their perspectives on access to lung cancer screening for individuals living with low income in order to improve equity in access to LCS.

METHODS

A theory-informed thematic analysis was conducted using data collected from 11 semi-structured interviews with FPs recruited from three primary care sites in downtown Toronto. Data was coded using the Systems Model of Clinical Preventative Care as a framework and interpretation was guided by the synergies of oppression analytical lens.

RESULTS

Four overarching themes describe FP perspectives on access to LCS for individuals living with low income: the degree of social disadvantage that influences lung cancer risk and opportunities to access care; the clinical encounter, where there is often a mismatch between the complex health needs of low income individuals and structure of health care appointments; the need for equity-oriented health care, illustrated by the neglect of structural origins of health risk and the benefits of a trauma-informed approach; and finally, the multiprong strategies that will be needed in order to improve equity in health outcomes.

CONCLUSION

An equity-oriented and interdisciplinary team based approach to care will be needed in order to improve access to LCS, and attention must be given to the upstream determinants of lung cancer in order to reduce lung cancer risk.

Physicians' preventive practices: more frequently performed for male patients and by female physicians

Background

We sought to analyze gender differences in General Practitioners’ (GP) preventive practices: variations according to the GP’s and the patient’s genders, separately and combined, and the homogeneity of GPs’ practices according to gender.

Methods

Fifty-two general practitioners volunteered to participate in a cross-sectional study. A sample of 70 patients (stratified by gender) aged 40–70 years was randomly chosen from each GP’s patient panel. Information extracted from the medical files was used to describe the GPs’ preventive practices for each patient: measurements of weight, waist circumference, glucose, and cholesterol; inquiry and counseling about smoking, alcohol consumption, diet, and physical activity, and dates of cervical smears and mammographies. An aggregate preventive score was calculated to assess the percentage of these practices performed by each GP for patients overall and by gender. Mixed models were used to test for gender differences.

Results

Questionnaires were collected in 2008–2009 for 71% of the 3640 patients and analyzed in June 2017.

Male patients and female GPs were associated with the most frequent performance of many types of preventive care. The aggregate preventive score was higher for male patients (OR = 1.60, 95% CI 1.47–1.75) and female GPs (OR = 1.35, 95% CI 1.05–1.73). There was no combined effect of the genders of the two protagonists. Female patients of male GPs appeared to receive preventive care least frequently and female GPs to deliver preventive care more consistently than their male colleagues.

Conclusion

Physicians need to be aware of these differences, for both patient gender and their own.

Uptake of Colorectal Cancer Screening by Physicians Is Associated With Greater Uptake by Their Patients

BACKGROUND & AIMS

Physicians' own screening practices might affect screening in their patients. We conducted a population-based study to evaluate whether family physicians who underwent colorectal cancer testing were more likely to have patients who underwent colorectal cancer testing.

METHODS

We collected demographic and health care information on residents of Ontario, Canada from administrative databases; the sample was restricted to individuals at average risk of colorectal cancer who were 52-74 years old as of April 21, 2016. We obtained a list of all registered physicians in the province; physicians (n = 11,434) were matched with nonphysicians (n = 45,736) on age, sex, and residential location. Uptake of colorectal tests was defined by a record of a fecal occult blood test in the past 2 years, flexible sigmoidoscopy in the past 5 years, or colonoscopy in the past 10 years. Patients were assigned to family physicians based on billing claim frequency, and then the association between colorectal testing in family physicians and their patients was examined using a modified Poisson regression model.

RESULTS

Uptake of colorectal tests by physicians and nonphysicians (median age 60 years; 71% men) was 67.9% (95% confidence interval [CI], 67.0%-68.7%) and 66.6% (95% CI, 66.2%-67.1%), respectively. Physicians were less likely than nonphysicians to undergo fecal occult blood testing and were more likely to undergo colonoscopy; prevalence ratios were 0.44 (95% CI, 0.42-0.47) and 1.24 (95% CI, 1.22-1.26), respectively. Uptake of colorectal tests by family physicians was associated with greater uptake by their patients (adjusted prevalence ratio, 1.10; 95% CI, 1.08-1.12).

CONCLUSIONS

Approximately one-third of physicians and nonphysicians are overdue for colorectal cancer screening. Patients are more likely to be tested if their family physician has been tested. There is an opportunity for physicians to increase their participation in colorectal cancer screening, which could, in turn, motivate their patients to undergo screening.

The colon cancer screening behaviours survey for South Asians: a pilot study of feasibility and psychometric evaluation

PURPOSE

The purpose of the study was to pilot test the English and Urdu version of the Colon Cancer Screening Behaviours Survey among South Asians in Canada. The first objective was to evaluate feasibility of administration, data collection using computer assisted personal interviewing software on a tablet, and response burden. The second objective was to examine the prevalence of colorectal cancer screening among South Asians and evaluate the psychometric properties of sub-scales in the survey.

METHODS

Purposive, network and snowball sampling were used to recruit participants for this cross-sectional study. Interviewer-led administration of the Colon Cancer Screening Behaviours Survey was conducted across two cities in Ontario, Canada. Qualitative data analysis assessed feasibility; and sub-scales were evaluated through principal component analysis, item-scale correlations, and construct validity using multiple linear and logistic regression.

RESULTS

A total of 328 South Asians participated, 47% Urdu speaking, and 53% English speaking. There was a 23% refusal rate to participate. Feasibility identified: (1) successful recruitment despite reasons for refusal; (2) problematic items and response categories; and (3) computer/tablet limitations. Principal component analysis identified 14 components that explained 68.7% of total variance; 34 items were retained after factor analysis. Internal consistency of 4 scales ranged from 0.79-0.91. There were significant differences in perceived barriers scale scores (- 12.21; 95% CI, - 17.13 to - 7.28; p <  0.0001) between those who participated and those who did not participate in screening. No association was found with years of residence and uptake of screening after adjustment (OR 0.91 (0.46-1.79), p = 0.783).

CONCLUSIONS

Recruitment and data collection methods are feasible among South Asians if functionality of the tablet selected is improved. The Colon Cancer Screening Behaviours Survey was finalized and retained items in sub-scales demonstrated good psychometric properties to assess behaviours for colon cancer screening among South Asians in Canada. The interviewer-led survey may be used by public health, cancer care or other health practitioners to describe or predict colorectal cancer screening behaviours among South Asians in similar settings or adapted and tested in other contexts.

A "Tea and Cookies" Approach: Co-designing Cancer Screening Interventions with Patients Living with Low Income

BACKGROUND

In our primary care organization, we have observed income gradients in cancer screening for our patients despite outreach. We hypothesized that outreach strategies could be improved upon to be more compelling for our patients living with low income.

OBJECTIVE

To use co-design to adapt our current strategies and create new strategies to improve cancer screening uptake for patients living with low income.

DESIGN

An exploratory, qualitative study in two phases: interviews and focus groups.

PARTICIPANTS

For interviews, we recruited 25 patient participants who were or had been overdue for cancer screening and had been identified by their provider as potentially living with low income. For subsequent focus groups, we recruited 14 patient participants, 11 of whom had participated in Phase I interviews.

APPROACH

To analyse written transcripts, we took an iterative, inductive approach using content analysis and drawing on best practices in Grounded Theory methodology. Emergent themes were expanded and clarified to create a derived model of possible strategies to improve the experience of cancer screening and encourage screening uptake for patients living with low income.

KEY RESULTS

Fear and competing priorities were two key barriers to cancer screening identified by patients. Patients believed that a warm and encouraging outreach approach would work best to increase cancer screening participation. Phone calls and group education were specifically suggested as potentially promising methods. However, these views were not universal; for example, women were more likely to be in favour of group education.

CONCLUSIONS

We used input from patients living with low income to co-design a new approach to cancer screening in our primary care organization, an approach that could be broadly applicable to other contexts and settings. We learned from our patients that a multi-modal strategy will likely be best to maximize screening uptake.

Associations between area-level deprivation, rural residence, physician density, screening policy and late-stage colorectal cancer in Canada

BACKGROUND

Important social disparities in colorectal screening exist in Canada. Few studies have assessed disparities further along the cancer control continuum. Here we assess the associations between social and material deprivation, physician density, rural residence, and the absence of provincial mail-based screening programs and colorectal cancer (CRC) stage at diagnosis.

METHODS

Colorectal cancer cases and stage data ("local or regional" if stage 0, I, or II, "late" if stage III or IV) were obtained through the Canadian Cancer Registry (2011-2015, N = 54,745). Cases were linked to 2006 Canadian Census Dissemination Area-level data on rural/urban status, exposure to a provincial mail-based screening program, and social and material deprivation (Pampalon Index quintile groups); and to Scott's Medical Database 2011 physician density data (<7 vs. ≥ 7/10,000). Age, sex, and predictor-adjusted Generalized estimating equation (GEE) Poisson models were used to determine independent associations between predictors and late-stage at diagnosis.

RESULTS

Half of CRC cases are diagnosed at stage III or IV (51 %), with younger age groups experiencing higher late-stage prevalence (57 % among those aged 18-49). The covariate-adjusted late-stage prevalence was 2-percentage points higher in most materially- and socially-deprived areas (95 % CI: 1 %, 4 %, in both, respectively) and in provinces with no mail-based screening programs (95 % CI: 1 %, 2 %). No significant differences were observed according to rural residence or physician density.

CONCLUSIONS

Social disparities in late-stage CRC diagnosis are modest. Continued surveillance of these disparities may be warranted as provinces continue to promote early cancer detection through screening, and stage distributions may change overtime.

Understanding those overdue for cancer screening by five years or more: A retrospective cohort study in Ontario, Canada

Populations that are more than just slightly overdue for breast, cervical and colorectal screening should likely be targeted for policy and practice interventions. We used provincial-level administrative data to describe the Ontario population who are screen-eligible for breast, cervical and colorectal cancers but overdue by at least five years. For each cancer screening type, we created three cohorts and a binary outcome: screened at least once in the previous five years or not, using March 31, 2017 as our index date. We conducted simple descriptive analyses as well as multivariable logistic regression, where age category, immigrant status, neighbourhood income quintile, region, urban/suburban/rural status, primary care model type, and healthcare utilization were included in the models. More than 20% of Ontarians eligible for each of breast, cervical and colorectal cancer screening respectively had no history of screening in the previous five years. In multivariable analyses, people were significantly more likely to have no recent screening history if they lived in lower-income neighbourhoods (e.g. adjusted odds ratio [95% confidence interval]: 0.59 [0.58-0.59] for cervical screening), were recent immigrants, did not have a primary care provider, had a provider who practiced in a traditional fee-for-service model. Despite the presence of three provincial organized screening programs, we have found that more than one-fifth of Ontarians who are eligible for each of breast, cervical and colorectal screening respectively have not been screened for five years or more. Ensuring that all Ontarians have access to high-quality primary care, may be crucial to increasing screening uptake.

Fecal occult blood test screening uptake among immigrants from Muslim majority countries: A retrospective cohort study in Ontario, Canada

Background

Colorectal cancer (CRC) is the second and third highest cause of cancer deaths among Canadian men and women, respectively. Population‐based screening through fecal occult blood testing (FOBT) has been proven to be effective in reducing CRC morbidity and mortality. Although participation in Ontario's organized CRC screening program has been increasing steadily since 2008, its uptake remains low among recent immigrant populations despite the known benefits of screening. To promote participation in CRC screening, it is imperative to understand both individual and system level barriers and enablers. Although a number of immigrant and nonimmigrant factors have been associated with low participation, there is a dearth of knowledge related to the religious affiliation in CRC screening uptake. Our study is among the first to examine this issue in Ontario, one of the most ethnically diverse Canadian provinces and preferred settlement destinations for immigrants.

Methods

We conducted a population‐based retrospective cohort study using linked health care administrative databases. Our cohort included Ontario residents, age 50‐74 who were eligible for FOBT from 1 April 2013 to 31 March 2015.

Results

We found that immigrants from the Middle East and North Africa and Eastern Europe and Central Asia had the lowest rates of screening. Furthermore, being born in a Muslim‐majority country was associated with lower FOBT screening even after controlling for other confounders including world region and income (ie, overall adjusted relative risk (ARR) of screening 0.92 [95% CI 0.90‐0.93]). Moreover, being enrolled in a primary care model, having a female primary care provider and having an internationally trained physician were associated with increased screening among immigrants from Muslim‐majority countries.

Conclusions

These findings can inform future efforts to improve screening uptake like: enhancing access to primary care providers and enrollment in primary care models, targeted FOBT education for male providers and providers not in a primary care model, development of culturally sensitive and appropriate educational materials, and use of interactive approaches for communication of cancer screening information.

Time trends in prostate cancer screening in Swiss primary care (2010 to 2017) - A retrospective study

Introduction

Following years of controversy regarding screening for prostate cancer using prostate-specific antigen, evidence evolves towards a more restrained and preference-based use. This study reports the impact of landmark trials and updated recommendations on the incidence rate of prostate cancer screening by Swiss general practitioners.

Methods

We performed a retrospective analysis of primary care data, separated in 3 time periods based on dates of publications of important prostate-specific antigen screening recommendations. 1: 2010-mid 2012 including 2 updates; 2: mid 2012-mid 2014 including a Smarter Medicine recommendation; 3: mid-2014—mid-2017 maintenance period. Period 2 including the Smarter Medicine recommendation was defined as reference period. We further assessed the influence of patient’s age and the number of prostate-specific-antigen (PSA) tests, by the patient and within each time period, on the mean PSA concentration. Uni- and multivariable analyses were used as needed.

Results

36,800 men aged 55 to 75 years were included. 14.6% had ≥ 2 chronic conditions, 11.7% had ≥ 1 prostate-specific antigen test, (mean 2.60 ng/ml [SD 12.3]). 113,921 patient-years were covered. Data derived from 221 general practitioners, 33.5% of GP were women, mean age was 49.4 years (SD 10.0), 67.9% used prostate-specific antigen testing. Adjusted incidence rate-ratio (95%-CI) dropped significantly over time periods: Reference Period 2: incidence rate-ratio 1.00; Period 1: incidence rate-ratio 1.74 (1.59–1.90); Period 3: incidence rate-ratio 0.61 (0.56–0.67). A higher number of chronic conditions and a patient age between 60–69 years were significantly associated with higher screening rate. Increasing numbers of PSA testing per patient, as well as increasing age, were independently and significantly associated with an increase in the PSA value.

Conclusion

Swiss general practitioners adapted screening behavior as early as evidence of a limited health benefit evolved, while using a risk-adapted approach whenever performing multiple testing. Updated recommendations might have helped to maintain this decrease. Further recommendations and campaigns should aimed at older patients with multimorbidity, to sustain a further decline in prostate-specific antigen screening practices.

Factors affecting access and use of preventive and weight management care: A public health lens

Obesity is an important risk factor for various chronic diseases. While people with obesity use the health system more and incur higher costs, they may forego using preventive care services (e.g., gynecological cancer screenings) due to issues of service use and service access. The aim of this paper was to use a public health lens to elucidate system level factors that affect healthcare access and utilization for preventive and weight management care by patients with obesity. Some elucidated factors include lack of access to a Primary Care Provider (PCP) and multidisciplinary healthcare settings, gender of the PCP, duration of medical visits and health professionals' attitudes about obesity. We highlight potential strategies for leaders to use when improving access and use of health services by patients with obesity in Canada and the need for future empirical studies in this research area.

Area-level income disparities in colorectal screening in Canada: evidence to inform future surveillance

Background

Participation in colorectal screening remains low even in countries with universal health coverage. Area-level determinants of low screening participation in Canada remain poorly understood.

Methods

We assessed the association between area-level income and two indicators of colorectal screening (having never been screened, having not been screened recently) by linking census-derived local area-level income data with self-reported screening data from urban-dwelling respondents to the Canadian Community Health Survey (50-75 years of age, cycles 2005 and 2007, n = 18,362) who reported no known risk factors for colorectal cancer. Generalized estimating equation Poisson models estimated the prevalence ratios and differences for having never been screened and having not been screened recently, adjusting for individual-level income, education, marital status, having a regular physician, age, and sex.

Results

About 53% of the study population had never been screened. Among individuals who had ever been screened, 35% had been screened recently. Adjusting for covariates, lower area-level income was associated with having never been screened [covariate-adjusted prevalence ratios: 1.24 for quartile 1; 95% confidence limits (cl): 1.16, 1.34; 1.25 for quartile 2; 95% cl: 1.15, 1.33; 1.15 for quartile 3; 95% cl: 1.08, 1.23]. Among individuals who had been screened in their lifetime, area-level income was not associated with having not been screened recently.

Conclusions

Lower area-level income is associated with having never been screened for colorectal cancer even after adjusting for individual socioeconomic factors. Those findings highlight the potential importance of socioeconomic contexts for colorectal screening initiation and merit attention in both future research and surveillance efforts.

The Role of Access to a Regular Primary Care Physician in Mediating Immigration-Based Disparities in Colorectal Screening: Application of Multiple Mediation Methods

BACKGROUND

Colorectal cancer screening participation is lower among recent immigrants than among Canadian-born individuals. We assessed whether this screening disparity is mediated by access to regular primary care physicians (PCP).

METHODS

Pooling years 2003 to 2014 of the Canadian Community Health Survey, lifetime screening in respondents aged 50 to 75 years of age who immigrated in the previous 10 years (n = 1,067) was compared with Canadian-born respondents (N = 102,366). Regression- and inverse probability weighting-based methods were used to estimate the total effect (TE) and controlled direct effect (CDE) of recent immigration on never having received either a stool- or endoscopic-based screening test. The proportion of the TE that would be eliminated if all had a PCP was computed using these estimates [proportion eliminated (PE) = (TE - CDE)/(TE - 1)]. Analyses were stratified by visible minority status and adjusted for income, rurality, age, sex, marital status, education, and exposure to a provincially organized colorectal screening program.

RESULTS

The prevalence of never having been screened was 71% and 57% in visible minority and white recent immigrants, respectively, and 46% in white Canadian-born respondents. If all had regular PCPs, there would be no reduction in the screening inequality between white recent immigrants and Canadian-born (null PE), and the inequality between visible minority immigrants and white Canadian-born may increase by 6% to 13%.

CONCLUSIONS

Ensuring all have regular PCPs may lead to greater screening gains among Canadian-born than recent immigrants.

IMPACT

Improving access to PCPs may increase colorectal screening overall, but not reduce immigration-based disparities screening. Alternative interventions to reduce this disparity should be explored.

Cancer Screening Among Patients Who Self-Identify as Muslim: Combining Self-Reported Data with Medical Records in a Family Practice Setting

Cancer screening is a core component of family medicine but screening inequalities are well documented in Canada for foreign-born persons. Although people of Muslim faith and culture are the fastest growing immigrant population in Canada, there is little information in the literature about their cancer screening practices. Determining screening gaps could inform practice-based quality improvement initiatives. We conducted a retrospective chart review combining patient-level medical record data with self-reported religious affiliation to examine the relationship between religion and cancer screening in a large multi-site urban family practice. Religious affiliation was classified as Muslim, other affiliation, or atheist/no religious affiliation. 5311 patients were included in the study sample. Muslim patients were significantly less likely to prefer English for spoken communication than the other two groups, less likely to be Canadian-born, more likely to have a female family physician, and were over-represented in the lowest income quintile. Muslim women were most likely to be up-to-date on breast cancer screening (85.2 vs. 77.5 % for those with other religions vs. 69.5 % for those with no religious affiliation). There were no significant differences in cancer screening by physician sex. In this pilot study conducted within a primary care practice, we used self-reported data on religious affiliation to examine possible inequities in cancer screening and observed intriguing variations in screening by self-identified religious affiliation. Future efforts to collect and use similar patient-level data should incorporate non-official languages and intensively outreach to patients with less health system contact. Regardless, the family medicine context may be the ideal setting to collect and act on patient-level sociodemographic data such as religious affiliation.

Disparities in breast cancer diagnosis for immigrant women in Ontario and BC: results from the CanIMPACT study

BACKGROUND

In Canada, clinical practice guidelines recommend breast cancer screening, but there are gaps in adherence to recommendations for screening, particularly among certain hard-to-reach populations, that may differ by province. We compared stage of diagnosis, proportion of screen-detected breast cancers, and length of diagnostic interval for immigrant women versus long-term residents of BC and Ontario.

METHODS

We conducted a retrospective cohort study using linked administrative databases in BC and Ontario. We identified all women residing in either province who were diagnosed with incident invasive breast cancer between 2007 and 2011, and determined who was foreign-born using the Immigration Refugee and Citizenship Canada database. We used descriptive statistics and bivariate analyses to describe the sample and study outcomes. We conducted multivariate analyses (modified Poisson regression and quantile regression) to control for potential confounders.

RESULTS

There were 14,198 BC women and 46,952 Ontario women included in the study population, of which 11.8 and 11.7% were foreign-born respectively. In both provinces, immigrants and long-term residents had similar primary care access. In both provinces, immigrant women were significantly less likely to have a screen-detected breast cancer (adjusted relative risk 0.88 [0.79-0.96] in BC, 0.88 [0.84-0.93] in Ontario) and had a significantly longer median diagnostic interval (2 [0.2-3.8] days in BC, 5.5 [4.4-6.6] days in Ontario) than long-term residents. Women from East Asia and the Pacific were less likely to have a screen-detected cancer and had a longer diagnostic interval, but were diagnosed at an earlier stage than long-term residents. In Ontario, women from Latin America and the Caribbean and from South Asia were less likely to have a screen-detected cancer, had a longer median diagnostic interval, and were diagnosed at a later stage than long-term residents. These findings were not explained by access to primary care.

CONCLUSIONS

There are inequalities in breast cancer diagnosis for Canadian immigrant women. We have identified particular immigrant groups (women from Latin America and the Caribbean and from South Asia) that appear to be subject to disparities in the diagnostic process that need to be addressed in order to effectively reduce gaps in care.

Reducing physician voiding cystourethrogram ordering in children with first febrile urinary tract infection: evaluation of a purposefully sequenced educational intervention

BACKGROUND

Physicians often fail to implement clinical practice guidelines. Our aim was to evaluate whether a purposefully sequenced, multifaceted educational intervention would increase physician adherence to a guideline for voiding cystourethrogram (VCUG) use following first urinary tract infection (UTI) in young children.

METHODS

Using a single centre, pretest-posttest design, we compared the proportion of guideline adherent VCUG orders and the VCUG ordering rate before and after three educational interventions (interactive lecture, clinical pathway, faxed reminder) selected and sequenced according to the PRECEDE (Predisposing, Reinforcing and Enabling Constructs in Educational Diagnosis and Evaluation) health promotion model.

RESULTS

One hundred and nine physicians ordered 219 VCUGs for 219 children. Following the interventions, there was an increase in the monthly proportion of adherent VCUGs ordered by pediatricians (analysis of variance (ANOVA) F(2,29) = 3.38, p = .048) and non-pediatricians (ANOVA F(2,28) = 14.71, p < .001). Also, pediatricians decreased their monthly VCUG ordering rate (linear trend incidence rate ratio 0.74, 95% confidence interval (CI) [0.54, 0.99]). Pediatricians were more likely to adhere with the guideline than were non-pediatricians (odds ratio 2.91, 95% CI [1.5, 5.5]).

CONCLUSION

Exposure to purposefully sequenced educational interventions based on the PRECEDE model was associated with increased adherence to guideline recommendations.

Cancer screening inequities in a time of primary care reform: a population-based longitudinal study in Ontario, Canada

BACKGROUND

Primary care has been reformed in recent years in Ontario, Canada, with a move away from traditional fee-for-service to enhanced fee-for-service and capitation-based models. It is unclear how new models have affected disparities in cancer screening. We evaluated whether Ontario's enhanced fee-for-service model was associated with a change in the gaps in cancer screening for people living with low income and people who are foreign-born.

METHODS

We conducted a population-based longitudinal analysis from 2002 to 2013 of Ontario family physicians who transitioned from traditional fee-for-service to enhanced fee-for-service. The binary outcomes of interest were adherence to cervical, breast and colorectal cancer screening recommendations. Outcomes were analyzed using mixed-effects logistic regression. Analyses produced annual odds ratios comparing the odds of being up-to-date for screening among patients in enhanced fee-for-service versus patients in traditional fee-for-service for each social stratum separately. We calculated the ratios of stratum-specific odds ratios to assess whether the transition from traditional to enhanced fee-for-service was associated with a change in screening gaps between immigrants and long-term residents, and between people in the lowest and highest neighbourhood income quintiles.

RESULTS

Throughout the study period, cancer screening was consistently lower among immigrants and among people in the lowest income quintile. Transition to enhanced fee-for-service was generally associated with increased screening uptake for all, however for most years, ratios of ratios were significantly less than 1 for all three cancer screening types, indicating that there was a widening of the screening gap between immigrants and long-term residents and between people living in the lowest vs. highest income quintile associated with transitions.

CONCLUSION

The transition to enhanced fee-for-service in Ontario was generally associated with a widening of screening inequities for foreign-born and low-income patients.

Breast screening participation and retention among immigrants and nonimmigrants in British Columbia: A population-based study

Breast cancer screening programs operate across Canada providing mammography to women in target age groups with the goal of reducing breast cancer mortality through early detection of tumors. Disparities in breast screening participation among socio‐demographic groups, including immigrants, have been reported in Canada. Our objectives were to: (1) assess breast screening participation and retention among immigrant and nonimmigrant women in British Columbia (BC), Canada; and (2) to characterize factors associated with screening among screening‐age recent immigrant women in BC. We examined 2 population‐based cohorts of women eligible for breast screening participation (537 783 women) and retention (281 052 women) using linked health and immigration data. Breast screening rates were presented according to socio‐demographic and health‐related variables stratified by birth country. Factors associated with screening among recent immigrant women were explored using Poisson regression. We observed marked variation in screening participation across birth country cohorts. Eastern European/Central Asian women showed low participation (37.9%) with rates from individual countries ranging from 35.0% to 49.0%. Participation rates for immigrant women from the most common birth countries, such as China/Macau/Hong Kong/Taiwan (45.7%), India (44.5%), the Philippines (45.9%), and South Korea (39.0%), were lower than the nonimmigrant rates (51.2%). Retention rates showed less variation by birth country; however, some disparities between immigrant and nonimmigrant groups persisted. Associations between screening indicators and study factors varied considerably across immigrant groups. Primary care physician visits were consistently positively associated with screening participation; this variable was also the only predictor associated with screening within each of the groups of recent immigrants. Our study provides unique data on both screening participation and retention among Canadian immigrant women compiled by individual country of birth. Our results are further demonstration that screening disparities exist among immigrant populations as well as in comparison with nonimmigrant women.

Barriers to cervical cancer screening faced by immigrants: a registry-based study of 1.4 million women in Norway

Background

Immigrants from certain low- and middle-income countries are more prone to cancers attributed to viral infections in early life. Cervical cancer is caused by human papillomavirus but is highly preventable by regular screening. We assessed participation among immigrants in a population-based cervical screening programme and identified factors that predicted non-adherence within different immigrant groups.

Methods

We used data from several nationwide registries. The study population consisted of 208 626 (15%) immigrants and 1 157 223 (85%) native Norwegians. Non-adherence was defined as no eligible screening test in 2008–12. We estimated prevalence ratios with 95% confidence intervals (CIs) for factors associated with non-adherence by modified Poisson regression.

Results

In total, 52% of immigrants were not screened. All immigrants showed 1.72 times higher non-adherence rates (95% CI 1.71–1.73) compared with native Norwegian women when adjusted for age and parity. The proportion of non-adherent immigrants varied substantially by region of origin and country of origin. Being unemployed or not in the workforce, being unmarried, having low income and having a male general practitioner was associated with non-adherence regardless of region of origin. Living <10 years in Norway was an evident determinant of non-adherence among most but not all immigrant groups.

Conclusions

An increasing proportion of immigrants and low screening participation among them pose new public health challenges in Europe. Immigrants are diverse in terms of their sociodemographic attributes and screening participation. Tailored information and service delivery may be necessary to increase cancer screening among immigrants.

Predictors of non-adherence to colorectal cancer screening among immigrants to Ontario, Canada: a population-based study

Though colorectal cancer (CRC) screening rates have increased over time in Ontario, Canada, immigrants continue to have lower rates of screening. This study examines the association between non-adherence to CRC screening and immigration, socio-demographic, healthcare utilization, and primary care physician characteristics among immigrants to Ontario. This is a population-based retrospective cross-sectional study that uses healthcare administrative databases housed at the Institute for Clinical Evaluative Sciences. Our cohort comprised immigrants aged 60 to 74 years who lived in Ontario on March 31, 2015 and who had been eligible for the Ontario Health Insurance Plan for at least 10 years. The outcome was lack of adherence to CRC screening with any modality (fecal occult blood test, flexible sigmoidoscopy, colonoscopy) on March 31, 2015. Our cohort contained 182,949 immigrants. Overall 70,134 (38%) individuals were not adherent to screening. Risk of non-adherence to CRC screening was higher among immigrants who were from low (adjusted relative risk [ARR] 1.35, 95%CI 1.28-1.42) or low-middle (ARR 1.27, 95%CI 1.24-1.30, population-attributable risk [PAR] 9.8%) income countries and refugees (ARR 1.09, 95%CI 1.06-1.11). Compared to those from the United States, Australia, and New Zealand, immigrants from most other world regions, particularly Eastern Europe and Central Asia (ARR 1.28, 95%CI 1.21-1.37), had higher risks of non-adherence. Non-immigration factors such as low healthcare use and lack of primary care enrolment also increased the risk of non-adherence to screening. These findings can be used to inform future efforts to improve uptake of CRC screening among immigrant groups.

Patient and physician characteristics affect adherence to screening mammography: A population-based cohort study

BACKGROUND

Screening mammograms are widely recommended biennially for women between the ages of 50 and 74. Despite the benefits of screening mammograms, full adherence to recommendations falls below 75% in most developed countries. Many studies have identified individual (obesity, smoking, socio-economic status, and co-morbid conditions) and primary-care physician parameters (physician age, gender, clinic size and cost) that influence adherence, but little data exists from large population studies regarding the interaction of these individual factors.

METHODS

We performed a historical cohort study of 44,318 Israeli women age 56-74 using data captured from electronic medical records of a large Israeli health maintenance organization. Univariate analysis was used to examine the association between each factor and adherence (none, partial or full) with screening recommendations between 2008-2014. Multivariate analysis was used to examine the significance of these factors in combination, using binary and multinomial logistic regression.

RESULTS

Among 44,318 women, 42%, 43% and 15% were fully, partially and non-adherent to screening recommendations, respectively. Factors associated with inferior adherence identified in our population included: smoking, obesity, low body weight, low socio-economic status, depression, diabetes mellitus and infrequent physician visits, while, women with ischemic heart disease, female physicians, physicians between the ages of 40 and 60, and medium-sized clinics were associated with higher screening rates. Most factors remained significant in the multivariate analysis.

CONCLUSIONS

Both individual and primary-care physician factors contribute to adherence to mammography screening guidelines. Strategies to improve adherence and address disparities in mammography utilization will need to address these factors.

Strategies to reach marginalized women for cervical cancer screening: A qualitative study of stakeholder perspectives

Background

Self-sampling for human papillomavirus (hpv) has the potential to reach marginalized populations that are underserved for cervical cancer screening. However, before implementing an alternative screening strategy such as self-sampling for under- and never-screened women, the key processes, facilitators, and barriers to reform need to be understood.

Methods

A descriptive qualitative study was conducted that involved semi-structured interviews with Canadian and international cancer screening health care providers and policy-makers. Respondents were purposively selected from a list of thirty stakeholders generated through an environmental scan. The interviews were transcribed verbatim and analyzed using directed content analysis.

Results

Nineteen stakeholders participated in the interviews. Most respondents thought that self-sampling was an appropriate cervical screening alternative for hard-to-reach populations, as it addressed barriers to cervical screening related to various social determinants of health. All respondents emphasized that transitioning to hpv primary screening would catalyze a policy shift towards self-sampling. Clinician respondents were less enthusiastic about self-sampling strategies since that discouraged women's appointments with primary care providers, because cervical screening offered an opportunity to discuss other preventive health topics. There also was little consensus between respondents on whether the state of evidence was satisfactory to integrate a self-sampling option into policy, or whether more Canadian research was needed.

Conclusion

Canadian cervical cancer screening stakeholders should collaborate to identify the knowledge gaps that researchers should address and leverage the existing literature to implement tailored, patient-centred alternative cervical screening strategies. The transition to hpv primary screening would be a key first step in the broad implementation of hpv self-sampling in Canada.

Cervical cancer screening uptake among HIV-positive women in Ontario, Canada: A population-based retrospective cohort study

Cervical cancer caused by oncogenic types of the human papillomavirus (HPV) is of concern among HIV-positive women due to impairment of immune responses required to control HPV infection. Our objectives were to describe patterns of cervical cancer screening using Pap cytology testing among HIV-positive women in Ontario, Canada from 2008 to 2013 and to identify factors associated with adequate screening. We conducted a retrospective, population-based cohort study among screen-eligible HIV-positive women using provincial administrative health data. We estimated annual proportions tested and reported these with 95% confidence intervals (CI). Next, using person-years as the unit of analysis, we identified factors associated with annual Pap testing using log-binomial regression. A total of 2271 women were followed over 10,697 person-years. In 2008, 34.0% (95%CI 31.1-37.0%) had a Pap test. By 2013, the proportion of HIV-positive women tested was 25.9% (95%CI 23.6-28.2%). Women who were most likely to undergo testing were younger, were immigrants from countries with generalized HIV epidemics, lived in the highest income neighbourhoods, had a female primary care physician, had two or more encounters per year with an infectious disease or internal medicine specialist, and had greater comorbidity. Nearly three in four HIV-positive women were under-screened despite all having universal insurance for medically-necessary services. Annual Pap testing decreased following the 2011-2013 release of new guidelines for a lengthened screen interval for average risk women and a billing disincentive. Clinic-based intervention such as physician alerts or reminders may be needed to improve screening coverage among HIV-positive women.

Health Care Providers’ Perspectives on Barriers and Facilitators to Cervical Cancer Screening in Vietnamese American Women

Introduction: Vietnamese American women (VAW) are diagnosed and die at twice the rate than White non-Hispanic American women (16.8/100,000 vs. 8.1/100,000 and 4.4/100,000 vs. 2.4/100,000, respectively). Despite efforts to increase cervical cancer (CC) screening among VAW, the participation rates are persistently low (69% to 81%). The purpose of this study was to explore health care providers’ (HCPs) perspectives on barriers and facilitators to CC screening in VAW. Method: This qualitative descriptive pilot study, used open-ended semistructured interviews with 10 HCPs. Results: The HCPs had two to 23 years treating VAW. Major barriers and facilitators identified by the HCPs were as follows: VAW’s decision making about CC screening; sexual health divide; language discordance, relying on interpreters; breaking suspicion; VAW’s exposure to health sources of CC screening; sustainable trust; and motivated health care practices. Discussion: HCPs perceived the reasons for VAW not being screened or delaying CC screening were due to their lack of knowledge, cultural barriers, language, and issues related to trust.

The readiness of German GPs to recommend and conduct cancer screening is associated with patient-physician gender concordance. Results of a survey

BACKGROUND

Cancer screening participation rates in Germany differ depending on patients' gender. International studies have found that patient-physician gender concordance fosters recommendation and conducting of cancer screening, and especially cancer screening for women.

OBJECTIVES

We aimed to ascertain whether gender concordance influences general practitioners' (GPs') rating of the usefulness of cancer screening, as well as their recommendations and readiness to conduct cancer screening in general practice in Germany.

METHODS

For an exploratory cross-sectional survey, 500 randomly selected GPs from all over Germany were asked to fill in a questionnaire on cancer screening in general practice between March and June 2015. We asked them to rate the usefulness of each cancer screening examination, how frequently they recommended and conducted them and whether they viewed GPs or specialists as responsible for carrying them out. We used multiple logistic regression to analyse gender effect size by calculating odds ratios.

RESULTS

Our study sample consisted of 139 GPs of which 65% were male. Male and female GPs did not differ significantly in their rating of the general usefulness of any of the specified cancer screening examinations. Male GPs were 2.9 to 6.8 times as likely to consider GPs responsible for recommending and conducting PSA testing and digital rectal examinations and were 3.7 to 7.9 times as likely to recommend and conduct these examinations on a regular basis.

CONCLUSION

Patient-physician gender concordance made it more likely that male-specific cancer screenings would be recommended and conducted, but not female-specific screenings. [Box: see text].

The Role of Physician Recommendation in Colorectal Cancer Screening Receipt Among Immigrant Chinese Americans

Chinese Americans have low colorectal cancer (CRC) screening rates. It is unclear whether physicians should offer all CRC screening modalities (fecal occult blood test [FOBT], sigmoidoscopy, colonoscopy) to Chinese Americans to increase screening. Seven hundred and twenty-five Chinese Americans were asked in a survey if their physician had ever recommended CRC screening and to self-report receipt and type of CRC screening. Participants whose physician had recommended all CRC screening modalities were significantly more likely to report ever having screening (adjusted odds ratio 4.29, 95% CI 1.26-14.68) and being up-to-date (4.06, 95% CI 2.13-7.74) than those who reported that their physician only recommended FOBT. Participants who received a recommendation of only one type of screening did not report a significant difference in ever having or being up-to-date for screening. A potential strategy to increase CRC screening among Chinese Americans is for clinicians to recommend all available CRC screening modalities to each patient.

Lay health educators within primary care practices to improve cancer screening uptake for South Asian patients: challenges in quality improvement

BACKGROUND

Cancer screening uptake is known to be low among South Asian residents of Ontario. The objective of this pilot study was to determine if lay health educators embedded within the practices of primary care providers could improve willingness to screen and cancer screening uptake for South Asian patients taking a quality improvement approach.

MATERIALS AND METHODS

Participating physicians selected quality improvement initiatives to use within their offices that they felt could increase willingness to screen and cancer screening uptake. They implemented initiatives, adapting as necessary, for six months.

RESULTS

Four primary care physicians participated in the study. All approximated that at least 60% of their patients were of South Asian ethnicity. All physicians chose to work with a preexisting lay health educator program geared toward South Asians. Health ambassadors spoke to patients in the office and telephoned patients. For all physicians, ~60% of South Asian patients who were overdue for cancer screening and who spoke directly to health ambassadors stated they were willing to be screened. One physician was able to track actual screening among contacted patients and found that screening uptake was relatively high: from 29.2% (colorectal cancer) to 44.6% (breast cancer) of patients came in for screening within six months of the first phone calls. Although physicians viewed the health ambassadors positively, they found the study to be time intensive and resource intensive, especially as this work was additional to usual clinical duties.

DISCUSSION

Using South Asian lay health educators embedded within primary care practices to telephone patients in their own languages showed promise in this study to increase awareness about willingness to screen and cancer screening uptake, but it was also time intensive and resource intensive with numerous challenges. Future quality improvement efforts should further develop the phone call invitation process, as well as explore how to provide infrastructure for lay health educator training and time.

Using self-reported data on the social determinants of health in primary care to identify cancer screening disparities: opportunities and challenges

Background

Data on the social determinants of health can help primary care practices target improvement efforts, yet relevant data are rarely available. Our family practice located in Toronto, Ontario routinely collects patient-level sociodemographic data via a pilot-tested survey developed by a multi-organizational steering committee. We sought to use these data to assess the relationship between the social determinants and colorectal, cervical and breast cancer screening, and to describe the opportunities and challenges of using data on social determinants from a self-administered patient survey.

Methods

Patients of the family practice eligible for at least one of the three cancer screening types, based on age and screening guidelines as of June 30, 2015 and who had answered at least one question on a socio-demographic survey were included in the study. We linked self-reported data from the sociodemographic survey conducted in the waiting room with patients’ electronic medical record data and cancer screening records. We created an individual-level income variable (low-income cut-off) that defined a poverty threshold and took household size into account. The sociodemographic characteristics of patients who were overdue for screening were compared to those who were up-to-date for screening for each cancer type using chi-squared tests.

Results

We analysed data for 5766 patients for whom we had survey data. Survey participants had significantly higher screening rates (72.9, 78.7, 74.4% for colorectal, cervical and breast cancer screening respectively) than the 13, 036 patients for whom we did not have survey data (59.2, 65.3, 58.9% respectively). Foreign-born patients were significantly more likely to be up-to-date on colorectal screening than their Canadian-born peers but showed no significant differences in breast or cervical cancer screening. We found a significant association between the low-income cut-off variable and cancer screening; neighbourhood income quintile was not significantly associated with cancer screening. Housing status was also significantly associated with colorectal, cervical and breast cancer screening. There was a large amount of missing data for the low-income cut-off variable, approximately 25% across the three cohorts.

Conclusion

While we were able to show that neighbourhood income might under-estimate income-related disparities in screening, individual-level income was also the most challenging variable to collect. Future work in this area should target the income disparity in cancer screening and simultaneously explore how best to collect measures of poverty.

Personal and provider level factors influence participation to cervical cancer screening: A retrospective register-based study of 1.3 million women in Norway

High coverage is essential for an effective screening programme. Here we present screening barriers and facilitators among 1.3 million women aged 25-69years eligible for screening within the Norwegian Cervical Cancer Screening Program (NCCSP). We defined non-adherence as no screening test in 2008-2012. We divided adherent women into those screened spontaneously, and those who had a smear after receiving a reminder from the NCCSP. Explanatory variables were extracted from several nationwide registers, and modelled by modified Poisson regression. In total, 34% of women were non-adherent. 31% of native Norwegians were non-adherent, compared to 50% of immigrants. Immigrant status was a strong predictor of non-adherence, but the vast majority of non-adherent women were still native Norwegians. Higher non-adherence rates were associated with having a male general practitioner (GP), a foreign GP, a young GP, and distance to the screening site. Being unmarried, having no children, having lower socioeconomic position and region of residence predicted non-adherence and, to a smaller extent, reminded adherence to screening. In contrast, previous experience with cervical abnormalities substantially increased adherence to screening. The population-based screening programme promotes equity by recruiting women who are less likely to participate spontaneously. However, socioeconomic disparities were evident in a country with a nationwide programme and a policy of equal access to health care. Initiatives aimed at removing practical and financial barriers to equitable screening delivery and at reducing the effect of sociodemographic attributes on screening participation are needed.

The Impact of Primary Care Providers on Patient Screening Mammography and Initial Presentation in an Underserved Clinical Setting

INTRODUCTION

Cancer screening is a key component of primary care, and access to regular screening mammography (SMG) is highly dependent on recommendation and referral by a primary care provider (PCP). Women with no health insurance or who are underinsured often lack access to a regular PCP and thus access to routine screening.

METHODS

We retrospectively reviewed the charts of 173 surgical patients diagnosed between January 2012 and December 2013. The main outcome variables were PCP status, method of cancer detection, and breast cancer stage at diagnosis. Additional variables included race, age at diagnosis, family history of breast and ovarian cancer, and medical comorbidities.

RESULTS

Patients with a PCP received more mammograms (SMG) compared with patients without a PCP (61 vs. 37 %; p = 0.003). The majority (73 %) of patients without a PCP presented symptomatically with a palpable mass versus 42 % of patients with a PCP. A significant difference was noted with regard to final pathologic stage of breast cancer between the two groups (p = 0.019), and Caucasian and African American patients were more likely to have locally advanced breast cancer.

CONCLUSIONS

Underserved patients with a PCP are more likely to present asymptomatically and at an earlier stage of breast cancer compared with patients without a PCP. Community engagement programs that build relationships with patients may help bring vulnerable patients into the healthcare system for routine screening. Moreover, PCP education regarding the subtleties of breast cancer screening guidelines and referral to a breast specialist is also critical in improving outcomes of underserved patients.

"I want to save my life": Conceptions of cervical and breast cancer screening among urban immigrant women of South Asian and Chinese origin

Background

Breast and cervical cancer screening rates remain low among immigrant women and those of low socioeconomic status. The Cancer Awareness: Ready for Education and Screening (CARES) project ran a peer-led multi-lingual educational program between 2012 and 2014 to reach under and never-screened women in Central Toronto, where breast and cervical cancer screening rates remain low.

The objective of this qualitative study was to better understand how Chinese and South Asian immigrants – the largest and most under-screened immigrant groups according to national and provincial statistics - conceive of breast and cervical cancer screening. We explored their experiences with screening to date. We explicitly inquired about their perceptions of the health care system, their screening experiences with family physicians and strategies that would support screening in their communities.

Methods

We conducted 22 individual interviews and two focus groups in Bengali and Mandarin with participants who had attended CARES educational sessions. Transcripts were coded through an iterative constant comparative and interpretative approach.

Results

Themes fell into five major, overlapping domains: risk perception and concepts of preventative health and screening; health system engagement and the embedded experience with screening; fear of cancer and procedural pain; self-efficacy, obligation, and willingness to be screened; newcomer barriers and competing priorities. These domains all overlap, and contribute to screening behaviours. Immigrant women experienced a number of barriers to screening related to ‘navigating newness’, including transportation, language barriers, arrangements for time off work and childcare. Fear of screening and fear of cancer took many forms; painful or traumatic encounters with screening were described. Female gender of the provider was paramount for both groups. Newly screened South Asian women were reassured by their first encounter with screening. Some Chinese women preferred the anonymous screening options available in China. Women generally endorsed a willingness to be screened, and even offered to organize women in their community hubs to access screening.

Conclusions

The experience of South Asian and Chinese immigrant women suggests that under and never-screened newcomers may be effectively integrated into screening programs through existing primary care networks, cultural-group specific outreach, and expanding access to convenient community -based screening.

Patients living with disabilities: The need for high-quality primary care

OBJECTIVE

To compare the potential risk factors for lower-quality primary care, the potential markers of unmet needs in primary care, and the willingness to participate in future research among primary care patients with versus without physical disabilities.

DESIGN

A waiting room survey using a convenience sample.

SETTING

A family health team (FHT) in Kitchener-Waterloo, Ont, with a designated Mobility Clinic.

PARTICIPANTS

A total of 40 patients seen at the FHT Mobility Clinic and 80 patients from the general patient population of the same FHT.

MAIN OUTCOME MEASURES

Socioeconomic status and social capital, number of self-reported emergency department visits and hospitalizations in the preceding year, and willingness of the patients in the 2 groups to participate in future research studies.

RESULTS

Patients from the Mobility Clinic were more than twice as likely to be receiving benefits or social assistance (75.0% vs 32.1%, P < .001), were twice as likely to report an annual household income of less than $40000 (58.6% vs 29.2%, P = .006), and were more likely to report their health status to be fair or poor (42.5% vs 16.2%, P = .002). Half of Mobility Clinic patients had visited the emergency department at least once in the preceding year, compared with 29.7% in the general patient population (P = .027). When asked if they would be willing to provide their health card number in the future so that it could be linked to health care data for research, 82.5% of Mobility Clinic patients agreed versus 55.0% of those in the general patient population (P = .004).

CONCLUSION

In this study, patients with disabilities were at a social disadvantage compared with their peers without disabilities and were more likely to use the emergency department, suggesting that they had unmet health needs. Future research should continue to explore this patient population and to investigate if an interprofessional primary health care team approach focused on patients with disabilities can help to increase quality of care.

Comparing stage of diagnosis of cervical cancer at presentation in immigrant women and long-term residents of Ontario: a retrospective cohort study

BACKGROUND

Globally, cervical cancer is the fourth most common cancer in women and 7th most common cancer overall. Cervical cancer is highly preventable with screening. Previous work has shown that immigrants are less likely to undergo screening than nonimmigrants in Ontario, Canada. We examined whether immigrant women are more likely to present with later stage cervical cancer than long-term residents of the province.

METHODS

We conducted a retrospective matched cohort study of women with cervical cancer diagnosed between 2010 and 2014 using provincial administrative health data. We compared the odds of late-stage diagnosis between immigrants and long-term residents, adjusting for socioeconomic measures, comorbidities and health care use. The outcome of interest was stage of cervical cancer diagnosis, defined as early (stage I) or late (stages II-IV). We confirmed results with a cohort of women with cancer diagnosed between 2007 and 2012.

RESULTS

Complete staging data were available for 218 immigrants and 1348 matched long-term residents. We found no association between immigrant status and stage at diagnosis (adjusted odds ratio [OR] 0.94, 95% confidence interval [CI] 0.63-1.39). Factors that did show significant association with late-stage diagnosis were physician characteristics, whether a woman had previously undergone screening and had visited a gynecologist in the past 3 years. These results were echoed in the 2007-2012 cohort (immigrants v. long-term residents, OR 0.94, 95% CI 0.71-1.20).

INTERPRETATION

Our results show that being an immigrant is not associated with late-stage diagnosis of cervical cancer in Ontario. Programs broadly aimed at immigrants may require a targeted approach to address higher-risk subgroups.

Breast cancer screening disparities among immigrant women by world region of origin: a population-based study in Ontario, Canada

Rates of mammography screening for breast cancer are disproportionately low in certain subgroups including low-income and immigrant women. The purpose of the study was to examine differences in rates of appropriate breast cancer screening (i.e., screening mammography every 2 years) among Ontario immigrant women by world region of origin and explore the association between appropriate breast cancer screening among these women groups and individual and structural factors. A cohort of 183,332 screening-eligible immigrant women living in Ontario between 2010 and 2012 was created from linked databases and classified into eight world regions of origin. Appropriate screening rates were calculated for each region by age group and selected sociodemographic, immigration, and healthcare-related characteristics. The association between appropriate screening across the eight regions of origin and selected sociodemographic, immigration, and health-related characteristics was explored using multivariate Poisson regression. Screening varied by region of origin, with South Asian women (48.5%) having the lowest and Caribbean and Latin American women (63.7%) the highest cancer screening rates. Factors significantly associated with lower screening across the world regions of origin included living in the lowest income neighborhoods, having a refugee status, being a new immigrant, not having a regular physical examination, not being enrolled in a primary care patient enrollment model, having a male physician, and having an internationally trained physician. Multiple interventions entailing cross-sector collaboration, promotion of patient enrollment models, community engagement, comprehensive and intensive outreach to women, and knowledge translation and transfer to physicians should be considered to address screening disparities among immigrant population. Consideration should be given to design and delivery of culturally appropriate and easily accessible cancer screening programs targeted at high- risk immigrant subgroups, such as women of South Asian origin, refugees, and new immigrants.
