The Core Competencies for Public Health in Canada: Opportunities and Recommendations for Modernization.

CONTEXT: The 2008 Public Health Agency of Canada's (PHAC's) "Core Competencies for Public Health in Canada" (the "Canadian core competencies") outline the skills, attitudes, and knowledge essential for the practice of public health. The core competencies represent an important part of public health practice, workforce development, and education in Canada and internationally. However, the core competencies are considered outdated and are facing calls for review, expansion, and revision. OBJECTIVE: To examine the literature on public health competencies to identify opportunities and recommendations for consideration when reviewing and updating the Canadian core competencies. METHODS: This narrative literature review included 4 components: 3 literature searches conducted between 2021 and 2022 using similar search strategies, as well as an analysis of competency frameworks from comparable jurisdictions. The 3 searches were conducted in collaboration with the Health Library to identify core competency-relevant scholarly and gray literature published in English since 2007. Reference lists of sources identified were also reviewed. During the data extraction process, one researcher screened each source, extracted competency-relevant information, and categorized these data into key findings. RESULTS: After identifying 2392 scholarly and gray literature sources, 166 competency-relevant sources were included in the review. Findings from these sources were synthesized into 3 main areas: (1) competency framework methodology and structure; (2) competencies to add; and (3) competencies to modify. DISCUSSION: These findings demonstrate that updates to Canada's core competencies are needed and overdue. Recommendations to support this process include establishing a formal governance structure for the competencies' regular review, revision, and implementation, as well as ensuring that priority topics applicable across all competency categories are integrated as overarching themes. Limitations of the evidence include the potential lack of applicability and generalizability to the Canadian context, as well as biases associated with the narrative literature review methodology.

The Governance of Core Competencies for Public Health: A Rapid Review of the Literature.

Core competencies for public health (CCPH) define the knowledge, skills, and attitudes required of a public health workforce. Although numerous sets of CCPH have been established, few studies have systematically examined the governance of competency development, review, and monitoring, which is critical to their implementation and impact. This rapid review included 42 articles. The findings identified examples of collaboration and community engagement in governing activities (e.g., using the Delphi method to develop CCPH) and different ways of approaching CCPH review and revision (e.g., every 3 years). Insights on monitoring and resource management were scarce. Preliminary lessons emerging from the findings point towards the need for systems, structures, and processes that support ongoing reviews, revisions, and monitoring of CCPH.

Public health physician perspectives on developing and deploying clinical practice guidelines during the 2009 H1N1 pandemic.

During the H1N1 outbreak of 2009, local public health units engaged in consultations with various levels of government to develop clinical practice guidelines. These guidelines provide specific clinical considerations around prevention, management, and treatment associated with the particular pathogen involved and are used by frontline healthcare professionals across many healthcare settings. In this article, we report on the lessons learned by Medical Officers of Health from across Canada on the guideline development and deployment processes and provide suggestions to improve guidelines development and deployment during future pandemic situations.

Health services restructuring in Alberta and the 2009 pandemic influenza-An untimely concurrence.

In the last 12 years, every Canadian province and territory has undertaken significant health services restructuring, with the pace of change accelerating recently. When the H1N1 Pandemic Influenza (PI) hit Alberta in the spring of 2009, the province had just begun a restructuring of health services of a scale unprecedented in Canada. The new province-wide entity, Alberta Health Services (AHS), was faced with mounting an effective response to a global communicable disease outbreak during a time of great organizational flux. In this retrospective, the authors reflect on challenges and opportunities presented during the AHS PI response related to the coordination of public health, laboratory services, emergency and disaster management, communications, and health services delivery. Lessons learned are shared that may be helpful to other provinces and territories as they continue to evolve their systems, so that they may be better prepared to respond to an untimely event such as a pandemic.

Public health: who, what, and why?

There has been renewed concern about the state of public health in Canada, with several recent articles in this journal suggesting that the discipline of public health is under threat and that there has been a significant erosion of its core infrastructure. We strongly agree with the need for a well-resourced formal public health system and preservation of capacity to carry out core public health functions, while also positing a complementary narrative that emphasizes the possibility for a broad notion of public health to persevere and thrive in the face of these challenges. We consider what public health is, who public health is, and why public health exists, and suggest that the answers to these questions point to opportunities to strengthen the necessary interdisciplinary approaches that can best address current and future public health concerns.

Assessment of four common underfive children illnesses Routine Health Management Information System data for decision making at Ilemela Municipal Council, Northwest Tanzania: A case series analysis.

BACKGROUND: In 2012, The Tanzania Ministry Of Health introduced the revised Routine Health Management Information System (RHMIS) modules and registers, and introduced the open source software for data collection at the district council level. Despite a series of data collection tools revisions, the quality of data collated from both public and private primary health care facilities has not been investigated. METHODS: A case series study design was conducted on underfive children outpatient registers and monthly reports on malaria, acute respiratory infections, acute diarrhoea and pneumonia from 10 randomly selected health facilities. The data was entered into excel software and exported to stata version 11 for analysis. The data was analyzed for completeness, timely report submission and reporting accuracy. RESULTS: The Study found that 62% of the expected data was complete. Around 40% of the facilities submitted reports on time. Private health facilities submitted monthly reports late compared to the public facilities (p-value=0.039). There was 26% over-reporting of diagnosis. Health centres tended to over-report more diagnoses by 11 times higher than the dispensaries. In addition, private owned health facilities tended to over-report more diagnoses by 6 times higher than public owned health facilities. CONCLUSION: The RHMIS data collected through out patients department (OPD) registers on four common underfive children's illnesses at ilemela municipality were of unsatisfactory quality in light of allocation of resource allocations in the comprehensive council health plan.

Breastfeeding difficulties and supports and risk of postpartum depression in a cohort of womenwho have given birth in Calgary: a prospective cohort study.

BACKGROUND: A link exists between breastfeeding difficulties and postpartum depression, and evidence shows that some breastfeeding promotion initiatives may increase maternal stress and contribute to risk of the condition. We conducted a prospective cohort study to determine whether breastfeeding difficulties affect the risk of postpartum depression and whether breastfeeding support modifies the relationship between breastfeeding difficulties and postpartum depression. METHODS: Between June and October 2010, we recruited 442 women who intended to breastfeed from all maternity hospitals in Calgary within 72 hours of giving birth to full-term, singleton infants. We administered questionnaires at birth and 6 weeks and 6 months postpartum, measuring breastfeeding difficulties, exposure to breastfeeding supports and postpartum depression. We used qualitative inquiry to measure breastfeeding support experiences. Postpartum depression was defined as a score of 10 or greater on the Edinburgh Postnatal Depression Scale or a self-reported diagnosis of depression in the first 6 months postpartum. RESULTS: A total of 386 women (87.3%) reported moderate to severe breastfeeding difficulties and 437 (98.9%) received some form of breastfeeding advice, help or support. Among women with breastfeeding difficulties, those who did not report a negative breastfeeding support experience were at decreased risk of postpartum depression (risk ratio 0.36). In the final regression model a negative breastfeeding support experience was a significant effect modifier of the relationship between breastfeeding difficulties and postpartum depression. INTERPRETATION: The quality of breastfeeding support is important not only for breastfeeding promotion but also for maternal mental health. Educating front-line caregivers to ensure that support experiences of breastfeeding women are positive can reduce the risk of postpartum depression.

The experience of nursing women with breastfeeding support: a qualitative inquiry.

BACKGROUND: Breastfeeding difficulties are a common occurrence, are highly personal and can vary from one infant to the next for any mother. Multiple sources of support, help and advice for breastfeeding are available to nursing mothers. Evidence suggests that the experience of the quality of breastfeeding supports may play an important role in maternal mental health and well-being in the postpartum period. We sought to explore the experiences of nursing mothers with support they received for breastfeeding in order to better inform and optimize existing breastfeeding supports and interventions. METHODS: We conducted a qualitative inquiry of nursing mothers' experiences with help, advice and support for breastfeeding. Participants were asked to provide open-ended, written accounts of their experiences with all sources of breastfeeding support received in the 6 months following the delivery of a healthy full-term infant in Calgary. We conducted qualitative thematic analysis, using constant comparison techniques. RESULTS: The sample included 86 mothers. Our analyses uncovered 4 emergent themes that contributed to the perceived quality of breastfeeding support: knowledge, effectiveness, sensitivity/emotional support and accessible when sought. INTERPRETATION: Our study provides a greater understanding of how mothers perceive the quality of the breastfeeding support that they receive, as well as what qualities of breastfeeding support are seen as beneficial or negative. The qualities contributing to the perception of breastfeeding support are important to inform and optimize perinatal care, and potentially reduce the risk of negative mental health outcomes for mothers.

Comparison of sampling methods for hard-to-reach francophone populations: yield and adequacy of advertisement and respondent-driven sampling.

BACKGROUND: Francophones who live outside the primarily French-speaking province of Quebec, Canada, risk being excluded from research by lack of a sampling frame. We examined the adequacy of random sampling, advertising, and respondent-driven sampling for recruitment of francophones for survey research. METHODS: We recruited francophones residing in the city of Calgary, Alberta, through advertising and respondentdriven sampling. These 2 samples were then compared with a random subsample of Calgary francophones derived from the 2006 Canadian Community Health Survey (CCHS). We assessed the effectiveness of advertising and respondent-driven sampling in relation to the CCHS sample by comparing demographic characteristics and selected items from the CCHS (specifically self-reported general health status, perceived weight, and having a family doctor). RESULTS: We recruited 120 francophones through advertising and 145 through respondent-driven sampling; the random sample from the CCHS consisted of 259 records. The samples derived from advertising and respondentdriven sampling differed from the CCHS in terms of age (mean ages 41.0, 37.6, and 42.5 years, respectively), sex (proportion of males 26.1%, 40.6%, and 56.6%, respectively), education (college or higher 86.7% , 77.9% , and 59.1%, respectively), place of birth (immigrants accounting for 45.8%, 55.2%, and 3.7%, respectively), and not having a regular medical doctor (16.7%, 34.5%, and 16.6%, respectively). Differences were not tested statistically because of limitations on the analysis of CCHS data imposed by Statistics Canada. INTERPRETATION: The samples generated exclusively through advertising and respondent-driven sampling were not representative of the gold standard sample from the CCHS. Use of such biased samples for research studies could generate misleading results.

Factors influencing the implementation of integrated management of childhood illness (IMCI) by healthcare workers at public health centers & dispensaries in Mwanza, Tanzania.

BACKGROUND: Integrated Management of Childhood Illness (IMCI) was developed by the World Health Organization (WHO) and the United Nations International Children's Fund (UNICEF) and aims at reducing childhood morbidity and mortality in resource-limited settings including Tanzania. It was introduced in 1996 and has been scaled up in all districts in the country. The purpose of this study was to identify factors influencing the implementation of IMCI in the health facilities in Mwanza, Tanzania since reports indicates that the guidelines are not full adhered to by the healthcare workers. METHODS: A cross-sectional study design was used and a sample size of 95 healthcare workers drawn from health centers and dispensaries within Mwanza city were interviewed using self-administered questionnaires. Structured interview was also used to get views from the city IMCI focal person and the 2 facilitators. Data were analyzed using SPSS and presented using figures and tables. RESULTS: Only 51% of healthcare workers interviewed had been trained. 69% of trained Healthcare workers expressed understanding of the IMCI approach. Most of the respondents (77%) had a positive attitude that IMCI approach was a better approach in managing common childhood illnesses especially with the reality of resource constraint in the health facilities. The main challenges identified in the implementation of IMCI are low initial training coverage among health care workers, lack of essential drugs and supplies, lack of onsite mentoring and lack of refresher courses and regular supportive supervision. Supporting the healthcare workers through training, onsite mentoring, supportive supervision and strengthening the healthcare system through increasing access to essential medicines, vaccines, strengthening supply chain management, increasing healthcare financing, improving leadership & management were the major interventions that could assist in IMCI implementation. CONCLUSIONS: The healthcare workers can implement better IMCI through the collaboration of supervisors, IMCI focal person, Council Health Management Teams (CHMT) and other stakeholders interested in child health. However, significant barriers impede a sustainable IMCI implementation. Recommendations have been made related to supportive supervision and HealthCare system strengthening among others.

Social equity in Human Papillomavirus vaccination: a natural experiment in Calgary Canada.

BACKGROUND: The Alberta Immunization Program offers a vaccine against the Human Papillomavirus (HPV) free of charge to all girls in Grades 5 and 9. The vaccine is provided in two different service delivery models depending upon the acceptance of the program by the local school board. Vaccinations may be provided "in-school" or in "community" through appointments at Public Health Clinics. The purpose of this study was to determine whether there was a difference in vaccine uptake in Calgary between the two service delivery models, "in-school" and "community", and to examine if socioeconomic status (SES) was a contributing factor. METHODS: Individual data from the Calgary Zone Public Health vaccination database for all grade 5 and 9 girls in Calgary for school years 2008-2011 were analyzed using descriptive statistics. These data included vaccination records for 35,592 girls. Logistic regression was used to examine the effect of delivery system and SES status on being vaccinated, controlling for school type. RESULTS: HPV vaccination completion rates were 75% (95% confidence interval = 74.7%, 75.8%) for girls with an "in-school" compared to 36% (95% confidence interval = 35.3%, 37.2%) for girls in schools with a "community" service delivery model. A girl's neighbourhood SES was related to the likelihood of being HPV vaccinated depending on the service delivery model available to her. For girls attending a Public school with an "in-school" delivery model, the proportion completing vaccination increased as SES decreased (high SES = 79%; medium SES = 79%; low SES = 83%; p-value<0.001). For girls attending Calgary Catholic School District schools with the "community" delivery model there was a decrease in immunization rates from high and mid to low SES (high SES = 41%; medium SES = 42%; low SES = 34%; p-value<0.001). These results show that those with lower SES were differentially disadvantaged by not having access to an "in-school" vaccination delivery model. CONCLUSION: Service delivery models make a difference in HPV vaccination completion rates and create inequities for health protection and disease prevention based on socioeconomic status.

Experiences of French speaking immigrants and non-immigrants accessing health care services in a large Canadian city.

French speakers residing in predominantly English-speaking communities have been linked to difficulties accessing health care. This study examined health care access experiences of immigrants and non-immigrants who self-identify as Francophone or French speakers in a mainly English speaking province of Canada. We used semi-structured interviews to gather opinions of recent users of physician and hospital services (N = 26). Language barriers and difficulties finding family doctors were experienced by both French speaking immigrants and non-immigrants alike. This was exacerbated by a general preference for health services in French and less interest in using language interpreters during a medical consultation. Some participants experienced emotional distress, were discontent with care received, often delayed seeking care due to language barriers. Recent immigrants identified lack of insurance coverage for drugs, transportation difficulties and limited knowledge of the healthcare system as major detractors to achieving health. This study provided the groundwork for future research on health issues of official language minorities in Canada.

Language barriers: use of regular medical doctors by Canada's official language minorities.

OBJECTIVE: To assess use of regular medical doctors (RMDs), as well as awareness and use of telephone health lines or telehealth services, by official language minorities (OLMs) in Canada. DESIGN: Analysis of data from the 2006 postcensal survey on the vitality of OLMs. SETTING: Canada. PARTICIPANTS: In total, 7691 English speakers in Quebec and 12 376 French speakers outside Quebec, grouped into those who experienced language barriers and those with no language barriers. MAIN OUTCOME MEASURES: Health services utilization (HSU) by the presence of language barriers; HSU measures included having an RMD, use of an RMD's services, and awareness of and use of telephone health lines or telehealth services. Multivariable models examined the associations between HSU and language barriers. RESULTS: After adjusting for age and sex, English speakers residing in Quebec with limited proficiency in French were less likely to have RMDs (adjusted odds ratio [AOR] 0.66, 95% CI 0.50 to 0.87) and to use the services of their RMDs (AOR 0.65, 95% CI 0.50 to 0.86), but were more likely to be aware of the existence of (AOR 1.50, 95% CI 1.16 to 1.93) and to use (AOR 1.43, 95% CI 0.97 to 2.11) telephone health lines or telehealth services. This pattern of having and using RMDs and telehealth services was not observed for French speakers residing outside of Quebec. CONCLUSION: Overall we found variation in HSU among the language barrier populations, with lower use observed in Quebec. Age older than 45 years, male sex, being married or in common-law relationships, and higher income were associated with having RMDs for OLMs.

A case of histamine fish poisoning in a young atopic woman.

Histamine fish poisoning, also known as scombroid poisoning, is a histamine toxicity syndrome that results from eating specific types of spoiled fish. Although typically a benign syndrome, characterized by self-limited flushing, headache, and gastrointestinal symptoms, we describe a case unique in its severity and as a precipitant of an asthma exacerbation. A 25-year-old woman presented to the emergency department (ED) with one hour of tongue and face swelling, an erythematous pruritic rash, and dyspnea with wheezing after consuming a tuna sandwich. She developed abdominal pain, diarrhea and hypotension in the ED requiring admission to the hospital. A diagnosis of histamine fish poisoning was made and the patient was treated supportively and discharged within 24 hours, but was readmitted within 3 hours due to an asthma exacerbation. Her course was complicated by recurrent admissions for asthma exacerbations.

Childhood vision screening in Canada: public health evidence and practice.

OBJECTIVES: Best practice guidelines recommend vision testing in children 3 to 5 years of age for the prevention of amblyopia; however, universal vision screening is controversial. In Canada, amblyopia screening can be the responsibility of physicians, optometrists, and/or Public Health. We review the evidence underlying preschool vision screening for amblyopia using an Evidence-based Public Health (EBPH) approach, and consider implications for the Public Health provision of universal screening programs for amblyopia in Canadian jurisdictions in light of present practices. METHODS: We searched the literature to address each major screening criterion (disease, test, treatment, program requirements) necessary to support preschool vision screening for amblyopia. We also reappraised papers cited in two systematic reviews related to the impact of vision screening. The Chief Medical Officer of Health of each province/territory was sent a short survey asking whether there currently was a Public Health preschool vision screening program in place and if so, for specifics about the program. RESULTS: An EBPH approach to the literature with respect to the criteria for screening and available intervention studies support amblyopia screening by Public Health. There is a public health divide in amblyopia screening practice in Canada; while some provinces maintain organized programs, others have chosen to delegate the task to other professionals, without a concurrent surveillance function to monitor disparities in uptake. CONCLUSIONS: Amblyopia deserves attention from Public Health. Efforts should be made to maintain existing programs, and provinces without organized screening programs should reconsider their role in the prevention of inequities with regard to preventable blindness in Canadian children.

Complementary and alternative medicine use among Chinese and white Canadians.

ABSTRACTOBJECTIVEThis study aimed to describe the level of complementary and alternative medicine (CAM) use and the factors associated with CAM use among Chinese and white Canadians.DESIGNA cross-sectional telephone survey conducted in English, Cantonese, and Mandarin.SETTINGCalgary, Alta.PARTICIPANTSChinese and white residents of Calgary aged 18 or older.MAIN OUTCOME MEASURESRates of use of 11 CAM therapies, particularly herbal therapy, massage, chiropractic care, and acupuncture; reasons for use of CAM therapies.RESULTSSixty percent of 835 Chinese respondents (95% confidence interval [CI] 56.5% to 63.2%) and 59% of 802 white respondents (95% CI 55.1% to 62.0%) had used CAM in the past year. Chinese respondents were more likely to use herbal therapy than white respondents were (48.7% vs 33.7%, P < .001), less likely to use massage (17.1% vs 30.4%, P < .001) and chiropractic care (8.4% vs 21.2%, P < .001), but equally likely to use acupuncture (8.3% vs 7.9%, P = .173). The common factor associated with herbal therapy, acupuncture, or massage use among Chinese and white respondents was receiving a CAM recommendation from a family member or friend. Factors unique to either Chinese or white CAM users varied by therapy. For example, herbal therapy use for Chinese respondents was associated with the presence of chronic disease (adjusted odds ratio [AOR] 2.15, 95% CI 1.09 to 4.24 for having 3 diseases compared with those without chronic disease), beliefs about the effectiveness of herbal therapy (AOR 1.56, 95% CI 1.12 to 2.17), and trust in herbal therapy practitioners (AOR 1.72, 95% CI 1.24 to 2.37). Herbal therapy use for white respondents was associated with the beliefs that herbal treatment had fewer side effects than prescription drugs (AOR 1.81, 95% CI 1.31 to 2.50) and that herbalists took a holistic approach (AOR 2.07, 95% CI 1.49 to 2.87).CONCLUSIONWhile the percentage of CAM use was similar in both groups, Chinese Canadians mainly used herbal therapy and white Canadians used a range of CAM therapies. Factors associated with CAM use varied with ethnicity and type of CAM therapy. Presence of chronic disease, however, was an important factor for Chinese Canadians. That finding suggests that Chinese Canadians use CAM for the treatment of chronic disease, while white Canadians use such therapies for disease treatment and health maintenance.

Variation in health services utilization among ethnic populations.

BACKGROUND: Although racial and ethnic disparities in health services utilization and outcomes have been extensively studied in several countries, this issue has received little attention in Canada. We therefore analyzed data from the 2001 Canadian Community Health Survey to compare the use of health services by members of visible minority groups and nonmembers (white people) in Canada. METHODS: Logistic regression was used to compare physician contacts and hospital admissions during the 12 months before the survey and recent cancer screening tests. Explanatory variables recorded from the survey included visible minority status, sociodemographic factors and health measures. RESULTS: Respondents included 7057 members of visible minorities and 114,255 white people for analysis. After adjustments for sociodemographic and health characteristics, we found that minority members were more likely than white people to have had contact with a general practitioner (adjusted odds ratio [OR] 1.28, 95% confidence interval [CI] 1.14-1.42), but not specialist physicians (OR 1.01, 95% CI 0.93-1.10). Members of visible minorities were less likely to have been admitted to hospital (OR 0.83, 95% CI 0.70- 0.98), tested for prostate-specific antigen (OR 0.64, 95% CI 0.52-0.79), administered a mammogram (OR 0.68, 95% CI 0.59-0.80) or given a Pap test (OR 0.47, 95% CI 0.39-0.56). INTERPRETATION: Use of health services in Canada varies considerably by ethnicity according to type of service. Although there is no evidence that members of visible minorities use general physician and specialist services less often than white people, their utilization of hospital and cancer screening services is significantly less.
