Diurnal choroid plexus function in mice depends on sex, age, and amyloid-β status.

Clinical practice guidelines (CPGs), protocols, and pathways are 3 different but related types of resources designed to guide practitioners toward evidence-based best practice. The terms are often poorly defined and used indiscriminately in academic literature. CPGs synthesize the best available evidence to inform clinical decision-making, typically offering graded recommendations based on the strength of evidence. Clinical protocols are more prescriptive, outlining specific actions for clinicians, rather than presenting alternative options as CPGs do. Clinical pathways, meanwhile, coordinate multidisciplinary care with a focus on the patient journey, including timing, sequencing, and referral processes. We employ the term (CGRs) throughout this review to refer to these 3 types of resources collectively. All CGRs aim to standardize care, contain costs, improve outcomes, and enhance efficiency. These objectives are especially important in rural and remote health care settings, which face unique challenges, including high staff turnover, limited access to diagnostic and therapeutic services, and infrastructure constraints. Health outcomes in these areas are generally poorer than in urban settings, and CGRs that are well-designed and effectively implemented can help mitigate the disparities. Creating trustworthy CPGs requires systematic evidence reviews and rigorous methodology, which can be difficult to achieve in rural and remote settings due to limited relevant literature and a scarcity of skilled personnel. As a result, it is not common for CPGs to be newly developed (de novo) specifically for these regions or for the First Nations populations who reside there. Instead, existing guidelines from urban, national, or international contexts are often adopted (no contextualization) or adapted (contextualized for the local setting). Adaptation—modifying a guideline to suit the local context—is generally preferred as it enhances relevance and feasibility. However, this process requires resources and expertise that may not be readily available. Simply adopting a CGR is more expedient if it can be legitimately deployed without alteration in the new environment. However, adopting CGRs risks inadvertently endorsing care that is culturally and contextually unsafe.
