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.

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.

Most parents who attended rounds found the experience beneficial, but medical trainees' views were mixed. The positive impact on parents, and the learning opportunities created in family-centered care and communication when parents are present on rounds, should be highlighted for trainees and other neonatal intensive care personnel.

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.

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.

BackgroundAt 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.MethodsThe 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.DiscussionThis 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.Electronic supplementary materialThe online version of this article (10.1186/s12891-019-2427-1) contains supplementary material, which is available to authorized users.

Introduction: Most military families experience mandatory relocation, or posting, several times during their 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 amplifi ed when a child in a military family has special needs within the health and educational systems. Th e purpose of this qualitative study was to gain a better understanding of Canadian Armed Forces (CAF) families' experiences in navigating health care systems on behalf of a child with Autism Spectrum Disorder (ASD), in the context of mandatory relocation, and to determine their recommendations for improved system navigation. Methods: Parents of children with ASD, where at least one parent serves in the CAF and had faced military-related relocation, were recruited. Semi-structured interviews were recorded, transcribed verbatim, and analyzed thematically. Results: A total of 13 participants represented 12 families and 15 children with ASD. Participants discussed two primary ways to support military families: (1) Improve communication between military-connected families with children with ASD, and (2) Improve transition coordination. Discussion: Th e recommendations made by military families echo those made in clinical professional association reports and recent Canadian research. International policy initiatives to off set the impacts of military family relocation may serve as examples to adapt to the provincial and territorial jurisdictions for both health and education in Canada.
