ABSTRACT
BACKGROUND: The preoperative period is a critically important time point in that patients' information needs are high and must be met. Traditional methods of patient education, such as those in the form of pamphlets, may not be the most effective and have been shown to result in low patient comprehension. The aim of this systematic review is to explore the use of preoperative supplementary educational videos. METHODS: A literature search using six databases was conducted. A total of 240 original research articles relating to preoperative educational videos were retrieved and screened for eligibility. RESULTS: 18 primary studies were identified and included in the review. Several outcomes were evaluated including knowledge, preparedness, and satisfaction, as well as psychological and physical wellbeing. Findings were varied, with many studies citing significant positive differences in these outcomes when patients viewed an educational video, while others report no differences. CONCLUSION: Although findings are slightly mixed, the use of videos to supplement patient education has considerable potential in a preoperative setting. More research is needed to reach definitive conclusions. PRACTICE IMPLICATIONS: We advocate for clinicians to challenge traditional methods of patient education and to consider exploring the possibility of integrating videos into routine preoperative education.

The delivery of ecosystem services by mobile organisms depends on the distribution of those organisms, which is, in turn, affected by resources at local and landscape scales. Pollinator-dependent crops rely on mobile animals like bees for crop production, and the spatial relationship between floral resources and nest location for these central-place foragers influences the delivery of pollination services. Current models that map pollination coverage in agricultural regions utilize landscape-level estimates of floral availability and nesting incidence inferred from expert opinion, rather than direct assessments. Foraging distance is often derived from proxies of bee body size, rather than direct measurements of foraging that account for behavioral responses to floral resource type and distribution. The lack of direct measurements of nesting incidence and foraging distances may lead to inaccurate mapping of pollination services. We examined the role of local-scale floral resource presence from hedgerow plantings on nest incidence of ground-nesting bees in field margins and within monoculture, conventionally managed sunflower fields in California's Central Valley. We tracked bee movement into fields using fluorescent powder. We then used these data to simulate the distribution of pollination services within a crop field. Contrary to expert opinion, we found that ground-nesting native bees nested both in fields and edges, though nesting rates declined with distance into field. Further, we detected no effect of field-margin floral enhancements on nesting. We found evidence of an exponential decay rate of bee movement into fields, indicating that foraging predominantly occurred in less than 1% of medium-sized bees' predicted typical foraging range. Although we found native bees nesting within agricultural fields, their restricted foraging movements likely centralize pollination near nest sites. Our data thus predict a heterogeneous distribution of pollination services within sunflower fields, with edges receiving higher coverage than field centers. To generate more accurate maps of services, we advocate directly measuring the autecology of ecosystem service providers, which vary by crop system, pollinator species, and region. Improving estimates of the factors affecting pollinator populations can increase the accuracy of pollination service maps and help clarify the influence of farming practices on wild bees occurring in agricultural landscapes.
