Mental health of Canadian children growing up in military families: The parent perspective.

A recent scoping review found that stressors involved in the military lifestyle (i.e., frequent relocation, parental absence, and risk of parental injury) may be associated with mental health issues among military-children. However, most of the included studies were conducted in the United States with little Canadian representation. To examine the degree to which the scoping review findings are relevant to the Canadian context, we conducted a qualitative study and interviewed 37 parents in Canadian military families. Through the use of a qualitative description approach and content analysis, three themes were identified: 1. Military lifestyle factors have an impact on child mental health; 2. Military life can promote both resilience and vulnerability; and 3. Military lifestyle impacts on parental mental health had an impact on children. These themes align with the scoping review findings asserting that military lifestyle factors can influence child mental health and have significant implications for health care providers working with military-connected children.

Navigating health care systems for military-connected children with autism spectrum disorder: A qualitative study of military families experiencing mandatory relocation.

BACKGROUND: Most military families experience mandatory relocation, or posting, several times during the military career. For Canadian military families who must access provincial or territorial health care systems, maintaining reasonable continuity of care is a persistent issue. Such challenges may be amplified when a child in a military family has special needs within the health and educational systems. OBJECTIVE: The purpose of this qualitative study was to gain a better understanding of Canadian Armed Forces families' experiences in navigating health care systems on behalf of a child with autism spectrum disorder (ASD) in the context of mandatory relocation. METHODS: Parents of children with ASD, where at least one parent serves in the Canadian Armed Forces and had faced military-related relocation, were recruited. Semi-structured interviews were recorded, transcribed verbatim, and analyzed thematically. RESULTS: Twelve participants represented 12 families and 15 children with ASD. Participants discussed two primary themes. (1) High mobility inherent in the military lifestyle can create disruptions and discontinuities to service, including delays in diagnosis or intervention, losses and gains in available services determined by the direction of posting, and the need to start health care access processes over again when relocating. (2) Navigating health systems for children with ASD creates personal stress and frustration related to relocating, and has career implications for both parents. CONCLUSIONS: Military-related relocation can create significant disruption in access to health and educational services for Canadian military families who have a child with ASD, and take a personal toll on these families.

Bridging the gap in genetics: a progressive model for primary to specialist care.

BACKGROUND: The rapid expansion of genetic knowledge, and the implications for healthcare has resulted in an increased role for Primary Care Providers (PCPs) to incorporate genetics into their daily practice. The objective of this study was to explore the self-identified needs, including educational needs, of both urban and rural Primary Care Providers (PCPs) in order to provide genetic care to their patients. METHODS: Using a qualitative grounded theory approach, ten key informant interviews, and one urban and two rural PCP focus groups (FGs) (n = 19) were conducted. All PCPs practiced in Southeastern Ontario. Data was analyzed using a constant comparative method and thematic design. The data reported here represent a subset of a larger study. RESULTS: Participants reported that PCPs have a responsibility to ensure patients receive genetic care. However, specific roles and responsibilities for that care were poorly defined. PCPs identified a need for further education and resources to enable them to provide care for individuals with genetic conditions. Based on the findings, a progressive stepped model that bridges primary and specialty genetic care was developed; the model ranged from PCPs identifying patients with genetic conditions that they could manage alone, to patients who they could manage with informal or electronic consultation to those who clearly required specialist referral. CONCLUSIONS: PCPs identified a need to integrate genetics into primary care practice but they perceived barriers including a lack of knowledge and confidence, access to timely formal and informal consultation and clearly defined roles for themselves and specialists. To address gaps in PCP confidence in providing genetic care, interventions that are directed at accessible just-in-time support and consultation have the potential to empower PCPs to manage patients' genetic conditions. Specific attention to content, timing, and accessibility of educational interventions is critical to address the needs of both urban and rural PCPs. A progressive framework for bridging primary to specialty care through a 'stepped' model for providing continuing medical education, and genetic care can was developed and can be used to guide future design and delivery of educational interventions and resources.

Imaging use for low back pain by Ontario primary care clinicians: protocol for a mixed methods study - the Back ON study.

BACKGROUND: At any one time, one in every five Canadians has low back pain (LBP), and LBP is one of the most common health problems in primary care. Guidelines recommend that imaging not be routinely performed in patients presenting with LBP without signs or symptoms indicating a potential pathological cause. Yet imaging rates remain high for many patients who present without such indications. Inappropriate imaging can lead to inappropriate treatments, results in worse health outcomes and causes harm from unnecessary radiation. There is a need to understand the extent of, and factors contributing to, inappropriate imaging for LBP, and to develop effective strategies that target modifiable barriers and facilitators. The primary study objectives are to determine: 1) The rate of, and factors associated with, inappropriate lumbar spine imaging (x-ray, CT scan and MRI) for people with non-specific LBP presenting to primary care clinicians in Ontario; 2) The barriers and facilitators to reduce inappropriate imaging for LBP in primary care settings. METHODS: The project will comprise an inception cohort study and a concurrent qualitative study. For the cohort study, we will recruit 175 primary care clinicians (50 each from physiotherapy and chiropractic; 75 from family medicine), and 3750 patients with a new episode of LBP who present to these clinicians. Clinicians will collect data in the clinic, and each participant will be tracked for 12 months using Ontario health administrative and self-reported data to measure diagnostic imaging use and other health outcomes. We will assess characteristics of the clinicians, patients and encounters to identify variables associated with inappropriate imaging. In the qualitative study we will conduct in-depth interviews with primary care clinicians and patients. DISCUSSION: This will be the first Canadian study to accurately document the extent of the overuse of imaging for LBP, and the first worldwide to include data from the main healthcare professions offering primary care for people with LBP. This study will provide robust information about rates of inappropriate imaging for LBP, along with factors associated with, and an understanding of, potential reasons for inappropriate imaging.

Primary care providers' lived experiences of genetics in practice.

To effectively translate genetic advances into practice, engagement of primary care providers (PCPs) is essential. Using a qualitative, phenomenological methodology, we analyzed key informant interviews and focus groups designed to explore perspectives of urban and rural PCPs. PCPs endorsed a responsibility to integrate genetics into their practices and expected advances in genetic medicine to expand. However, PCPs reported limited knowledge and difficulties accessing resources, experts, and continuing education. Rural practitioners' additional concerns included cost, distance, and poor patient engagement. PCPs' perspectives are crucial to develop relevant educational and systems-based interventions to further expand genetic medicine in primary care.

Driving problems in patients with rheumatoid arthritis.

OBJECTIVE: To assess driving problems experienced by patients with rheumatoid arthritis (RA) and to examine the relationship between functional status and driving difficulty. METHODS: Using the South Eastern Ontario Medical Organization (SEAMO) database, we identified 721 patients with RA from both urban and rural backgrounds. They completed a cross-sectional, self-administered mail survey that included the Health Assessment Questionnaire (HAQ-DI) and a co-morbidity questionnaire. We assessed the proportion of drivers versus non-drivers and patients who reported difficulty driving and who used vehicle adaptations. RESULTS: Survey response rate was 74% and 92.2% of the subjects were current drivers. Fifty percent of the current drivers reported a little difficulty, 6.8% reported quite a bit of difficulty, and 1.5% a great deal of difficulty driving. Major reasons given for why RA limited their driving were stiffness and pain. Frequent use of mobility aids (adjusted odds ratio, OR: 5.85), HAQ-DI > or = 1 (adjusted OR: 3.40), and older age (adjusted OR: 1.04) were significant predictors of an individual with RA discontinuing driving. Higher levels of disability (HAQ-DI) were associated with a greater number of problems reported with driving and with curtailment of driving. A multivariate logistic regression determined that having a HAQ-DI > or = 1 (adjusted OR: 4.3) and difficulties sitting in the vehicle (adjusted OR: 2.9) were associated with RA limiting driving. CONCLUSION: Over 50% of respondents reported some degree of difficulty driving due to their RA. Scores on HAQ-DI > or = 1 were associated with difficulty driving. Further validation of our findings needs to be performed.

Randomised equivalence trial comparing three month and six month follow up of patients with hypertension by family practitioners.

OBJECTIVE: To compare blood pressure control, satisfaction, and adherence to drug treatment in patients with treated hypertension followed up by their family physicians either every three months or every six months for three years. DESIGN: Randomised equivalence clinical trial. Settings 50 family practices in south eastern Ontario, Canada. PARTICIPANTS: 609 patients aged 30-74 years with essential hypertension receiving drug treatment whose hypertension had been controlled for at least three months before entry into the study. RESULTS: 302 patients were randomly assigned to follow up every three months and 307 to follow up every six months. Baseline variables in the two groups were similar. As expected, patients in the six month group had significantly fewer visits, but patients in both groups visited their doctor more frequently than their assigned interval. Mean blood pressure was similar in the groups, as was control of hypertension. Patient satisfaction and adherence to treatment were similar in the groups. About 20% of patients in each group had blood pressures that were out of control during the study. CONCLUSIONS: Follow up of patients with treated essential hypertension every six months is equivalent to follow up every three months. Patient satisfaction and adherence to treatment are the same for these follow up intervals. As about 20% of patients' hypertension was out of control at any time during the study in both groups, the frequency of follow up may not the most important factor in the control of patients' hypertension by family practitioners.

Pragmatic controlled clinical trials in primary care: the struggle between external and internal validity.

BACKGROUND: Controlled clinical trials of health care interventions are either explanatory or pragmatic. Explanatory trials test whether an intervention is efficacious; that is, whether it can have a beneficial effect in an ideal situation. Pragmatic trials measure effectiveness; they measure the degree of beneficial effect in real clinical practice. In pragmatic trials, a balance between external validity (generalizability of the results) and internal validity (reliability or accuracy of the results) needs to be achieved. The explanatory trial seeks to maximize the internal validity by assuring rigorous control of all variables other than the intervention. The pragmatic trial seeks to maximize external validity to ensure that the results can be generalized. However the danger of pragmatic trials is that internal validity may be overly compromised in the effort to ensure generalizability. We are conducting two pragmatic randomized controlled trials on interventions in the management of hypertension in primary care. We describe the design of the trials and the steps taken to deal with the competing demands of external and internal validity. DISCUSSION: External validity is maximized by having few exclusion criteria and by allowing flexibility in the interpretation of the intervention and in management decisions. Internal validity is maximized by decreasing contamination bias through cluster randomization, and decreasing observer and assessment bias, in these non-blinded trials, through baseline data collection prior to randomization, automating the outcomes assessment with 24 hour ambulatory blood pressure monitors, and blinding the data analysis. SUMMARY: Clinical trials conducted in community practices present investigators with difficult methodological choices related to maintaining a balance between internal validity (reliability of the results) and external validity (generalizability). The attempt to achieve methodological purity can result in clinically meaningless results, while attempting to achieve full generalizability can result in invalid and unreliable results. Achieving a creative tension between the two is crucial.
