Human Factor Health Data Interoperability.

Comprehensive health data interoperability is recognized as an essential element of high-functioning and accountable health service. Canada is lagging in health data interoperability compared to international comparators, and lacks a comprehensive approach to human factor interoperability, defined as system-level relationships that impact the capacity of health sector stakeholders to adopt harmonized health data standards and technology. Without addressing these system-level relationships, the adoption of harmonized health data standards and technology will be obstructed and Canadians will be underserved. The proposed health data interoperability framework articulates the factors that Canada needs to address to optimize health data design to support quality health programs and services.

Predicting family physician physical activity electronic medical record inputs.

OBJECTIVE: To compare characteristics of patients with and without physical activity noted in primary care electronic medical records. METHODS: We used pan-Canadian family physician electronic medical record data from the Canadian Primary Care Sentinel Surveillance Network (CPSSSN) to compare patient and provider characteristics on one visit per patient selected at random. Since patients were nested by providers, univariate statistics were explored then a multilevel model was constructed. RESULTS: The dataset included 769,185 patients, of whom 14,828 (1.9%) had physical activity information documented. Male patients, aged 25-34.9, no comorbidities prior to the random visit date, moderate or elevated blood pressure risk categories prior to the random visit date, the least materially deprived quintile, and with median body mass index in the normal category prior to the random visit date had the most physical activity mentions. Of the 879 family physicians in the sample, just over half (56.1%) documented physical activity at least once across their patients. More female physicians and physicians who practised in academic sites documented physical activity. In a two-level logistic model to predict physical activity documented in the randomly selected visit: older than mean patient age, having fewer comorbidities, younger than mean family physician age, academic teaching sites, and electronic medical record systems were statistically significant covariates. CONCLUSIONS: This work adds to existing literature by describing the frequency and the patient and family physician characteristics of physical activity documentation in the Canadian primary care context. Overall, patient physical activity was rarely documented in electronic medical records.

Scoping review of cytolytic vaginosis literature.

BACKGROUND: Cytolytic vaginosis (CV) is a little-known, controversial condition that is typically not considered for women presenting with vulvovaginitis symptoms. Objective: The objective of this scoping review was to identify and compile the global evidence on CV. METHODS: A medical librarian searched Prospero, Wiley Cochrane Library, Ovid Embase, Ovid Medline, EBSCO CINAHL, ProQuest Dissertations and Theses Global, and Scopus, from inception to April 4, 2019 and updated to October 17, 2021. Studies were eligible if they discussed CV. Two independent reviewers conducted study selection and data extraction. RESULTS: Sixty-four studies were identified, with 67% of studies (n = 43) published since 2007. Studies were from around the world, including the United States (28%, n = 18), Brazil (11%, n = 7), Portugal (11%, n = 7), and China (11%, n = 7). Fifty percent of studies (n = 32) were reviews; the remainder were observational; and of these, 78% (n = 25) were cross-sectional. The most frequent topics included: diagnosis (19%, n = 12), prevalence (17%, n = 11), and overview of CV (50%, n = 32). Evidence for prevalence in symptomatic women (median prevalence of 5%, interquartile range 3%-8%) was based only on 16% of studies (n = 10) with minimal evidence on prevalence in asymptomatic women and across different geographic regions. Microbiological findings, including abundant lactobacilli and fragmented epithelial cells, were found useful to distinguish between CV and vulvovaginal candidiasis, and Lactobacillus crispatus was noted to dominate the vaginal flora in women with CV. Most studies used subjective criteria to diagnose CV as the condition lacks gold-standard microscopic criteria. The suggested primary treatment (baking soda irrigations) was largely based on expert opinion, and there was minimal evidence on associations between CV and other conditions. CONCLUSION: Knowledge gaps currently exist in all realms of CV research. Additional research is needed to confirm the validity of CV and ensure that women are diagnosed and treated effectively.

The Nurse Practitioner Workforce in Western Canada: A Cross-Sectional Practice Analysis Comparison.

Regular examination of health workforce data is essential given the pace of health system and legislative changes. Health workforce studies pertaining to nurse practitioner (NP) practice are needed to examine the gaps between work activities, policy, human resource supply, or for population needs. Jurisdictional comparison studies can provide essential information about NP practice for governments to respond to health workforce deficiencies or engage in service planning. In Canada, there is limited provincial-territorial jurisdictional NP workforce data to support health planning or policy change. This descriptive cross-sectional study was to examine the similarities and differences in practice patterns of Canadian NPs. In 2016 and 2017, an electronic survey was sent to all 852 registered NPs in three Canadian provinces, yielding a large convenience sample of 375 NP respondents. The results of this study underscore the value of NPs' extensive registered nurse expertize as well as their ability to serve diverse patient populations, work in varied healthcare settings, and provide care to medically complex patients. The study findings also show that NPs in all three jurisdictions work to their full scope of practice, in both rural and urban settings. This study is the first to compare NP workforce data across multiple Canadian jurisdictions simultaneously. Studies of this type are valuable tools for understanding the demographics, education, integration, and employment activities of NPs and can aid governments in addressing workforce planning.

Association between continuity and access in primary care: a retrospective cohort study.

BACKGROUND: Continuity of care is a tenet of primary care. Our objective was to explore the relation between a change in access to a primary care physician and continuity of care. METHODS: We conducted a retrospective cohort study among physicians in a primary care network in southwest Alberta who measured access consistently between 2009 and 2016. We used time to the third next available appointment as a measure of access to physicians. We calculated the provider and clinic continuity, discontinuity and emergency department use based on the physicians' own panels. Physicians who improved, worsened or maintained their level of access within a given year were assessed in multilevel models to determine the association with continuity of care at the physician and clinic levels and the emergency department. RESULTS: We analyzed data from 190 primary care physicians. Physicians with improved access increased provider continuity by 6.8% per year, reduced discontinuity by 2.1% per year, and decreased emergency department encounters by 78 visits per 1000 patients per year compared to physicians with stable access. Physicians with worsening access had a 6.2% decrease in provider continuity and an increased number of emergency department encounters (64 visits per 1000 panelled patients per year) compared to physicians with stable access. INTERPRETATION: Changes in access to primary care can affect whether patients seek care from their own physician, from another clinic or at the emergency department. Improving access by reducing the delay in obtaining an appointment with one's primary care physician may be one mechanism to improve continuity of care.

A survey of nurse practitioner controlled drugs and substances prescribing in three Canadian provinces.

AIMS AND OBJECTIVES: In Canada, nurse practitioners (NP) were legally authorised to prescribe controlled drugs and substances (CDS) in 2012. The objective of this study was to understand current NP-CDS prescribing in Alberta, Manitoba and Saskatchewan, Canada. This study is a component of a larger three-phase survey of NP practice patterns in these same provinces. BACKGROUND: Nurse practitioners are nurses with a graduate degree who have the legal authority to perform expanded functions in health systems, including prescribing CDS. Given the novelty of CDS prescribing for NPs in Canada, little is known about this component of their role. DESIGN: A secondary analysis of survey data collected between March 2016 and May 2017 was used to examine NP-CDS-prescribing patterns and identify potential associated factors. METHODS: Nurse practitioners in Alberta, Manitoba and Saskatchewan were invited to complete a professional practice pattern survey. The survey was administered through a secure electronic data collection software application (redcap). In the practice pattern survey, 42 variables from 15 distinct conceptual questions were analysed in this study as potential predictors of NP-CDS prescribing within a purposeful selection ordinal logistic regression model. This scientific submission has been assessed for accuracy and completeness using the Equator STROBE guideline criteria (see Appendix S1). RESULTS/FINDINGS: Five variables were found to be associated with an increased odds of more frequent NP-CDS prescribing in addition to three confounders/clinically relevant variables. Factors commonly associated with an increased frequency of NP-CDS prescribing relate to location of practice, area of practice, previous nursing experience, team environments and common diagnoses. CONCLUSION: Little is known about NP-CDS prescribing. Understanding this important component of the NPs emerging legal scope of professional practice can contribute to the continued refinement of this role as well as support ongoing enquiry into the causes of, and potential interventions to prevent, the present opioid overdose deaths occurring while under an active prescription. RELEVANCE TO CLINICAL PRACTICE: Understanding factors that influence NP-CDS prescribing has relevance to the current drug-related prescription fatalities crisis in all countries.

Prevalence and predictors of booster seat use in Alberta, Canada.

OBJECTIVE: To determine the prevalence of booster seat misuse in a Canadian province and identify determinants of non-use. METHODS: A cross-sectional study using parking lot interviews and in-vehicle restraint inspections by trained staff was conducted at 67 randomly selected childcare centres across Alberta. Only booster-eligible children were included in this analysis. Odds ratios (OR) and 95% confidence intervals (CI) are reported using unadjusted and adjusted logistic regression. RESULTS: Overall, 23% of children were not in a booster seat, and in 31.8% of cases there was evidence of at least one misuse. Non-use increased significantly by age, from 22.2% for children 2 years of age to 47.8% for children 7 years of age (p = 0.02). Children who were at significantly increased risk of booster seat non-use were those in vehicles with drivers who could not recall the booster seat to seatbelt transition point (OR: 4.54; 95% CI: 2.05-10.06) or drivers who were under the age of 30 (OR: 3.54; 95% CI: 1.45-8.62). A front row seating position was also associated with significantly higher risk of nonuse (OR: 18.00; 95% CI: 2.78-116.56). Children in vehicles with grandparent drivers exhibited significantly decreased risk of booster seat non-use (OR: 0.21; 95% CI: 0.05-0.85). CONCLUSION: Messaging should continue to stress that the front seat is not a safe place for any child under the age of 9 as well as remind drivers of the booster seat to seatbelt transition point, with additional emphasis placed on appealing to parents under the age of 30. Future research should focus on the most effective means of communicating booster seat information to this group. Enacting mandatory booster seat legislation would be an important step to increase both awareness and proper use of booster seats in Alberta.

The pot calling the kettle black: the extent and type of errors in a computerized immunization registry and by parent report.

BACKGROUND: Accurate classification of children's immunization status is essential for clinical care, administration and evaluation of immunization programs, and vaccine program research. Computerized immunization registries have been proposed as a valuable alternative to provider paper records or parent report, but there is a need to better understand the challenges associated with their use. This study assessed the accuracy of immunization status classification in an immunization registry as compared to parent report and determined the number and type of errors occurring in both sources. METHODS: This study was a sub-analysis of a larger study which compared the characteristics of children whose immunizations were up to date (UTD) at two years as compared to those not UTD. Children's immunization status was initially determined from a population-based immunization registry, and then compared to parent report of immunization status, as reported in a postal survey. Discrepancies between the two sources were adjudicated by review of immunization providers' hard-copy clinic records. Descriptive analyses included calculating proportions and confidence intervals for errors in classification and reporting of the type and frequency of errors. RESULTS: Among the 461 survey respondents, there were 60 discrepancies in immunization status. The majority of errors were due to parent report (n = 44), but the registry was not without fault (n = 16). Parents tended to erroneously report their child as UTD, whereas the registry was more likely to wrongly classify children as not UTD. Reasons for registry errors included failure to account for varicella disease history, variable number of doses required due to age at series initiation, and doses administered out of the region. CONCLUSIONS: These results confirm that parent report is often flawed, but also identify that registries are prone to misclassification of immunization status. Immunization program administrators and researchers need to institute measures to identify and reduce misclassification, in order for registries to play an effective role in the control of vaccine-preventable disease.

Transmission of pandemic influenza A (H1N1) 2009 within households: Edmonton, Canada.

BACKGROUND: In April 2009, a novel influenza A, subtype H1N1, now referred to as the Pandemic (H1N1) 2009 virus (pH1N1), began circulating in countries around the world. Describing the transmission characteristics of this novel influenza A virus is important to predict current, and future, disease spread. The Public Health response to the first wave of pH1N1 in Alberta focused on the identification and management of secondary cases within households. OBJECTIVES: The purpose of this study was to describe transmission characteristics of pH1N1 in households in Edmonton, the capital city of Alberta, during the first wave, and to identify the serial interval and secondary attack rate (SAR) in this setting. STUDY DESIGN: This is a prospective analysis of pH1N1 household transmission within 87 urban Canadian households between April 30 and June 9, 2009; with each household having at least one laboratory-confirmed case. The secondary attack rate was calculated in the 262 household contacts using a weighted average by number of susceptible individuals in each household. The serial interval, or time to illness in secondary cases, was analyzed using survival analysis with a Weibull model. RESULTS: Within the 87 households, 42 (48.3%) had no secondary cases develop; 25 (28.7%) had one secondary case develop; and 20 (22.9%) had more than one secondary case develop. The secondary attack rate did not decrease with increasing household size and households with two members exhibited the lowest secondary attack rate at 14.1%. Children under the age of 19, and individuals with an underlying medical condition, were at increased risk (p<0.05) of becoming a secondary case. The overall secondary attack rate among the 262 susceptible household contacts was 30.2% (95% CI: 12.6-52.2). The median serial interval for pH1N1 transmission was 3.4 days (95% CI: 2.9-3.9). CONCLUSIONS: The identified transmission characteristics of pH1N1 among Canadian households differ slightly from other previously reported North American estimates, but are in keeping with historical transmission rates of pandemic influenza viruses.
