Best nutrition practice across the stroke care continuum: Using PEN & other evidence-based information sources E Eppler, Vancouver, British Columbia
Introduction/Background Best practices are recommendations that are supported by research evidence andinformed by expert perspective, judgment and experience. Best practices produce effective health outcomes. Stroke Care Best Practices describe the most effective policies, processes and interventions for stroke prevention, treatment and rehabilitation (1, 2). This poster describes a dietitian's experiences using the evidence-based practice cycle to determine best nutrition practice across the continuum of stroke care. Figures 1 & 2, below,depict the evidence-based practice cycle and best practice, respectively.

Figure 2: Best Practice Define Implement Disseminate Research generates evidence used in developing best practice • Standards • Guidelines • Protocols • Education • Care Paths Best Practice Resources Connect research and practice Expert judgment is used in conducting systematic reviews and applying the evidence-based practice cycle. The dietitian applies and adapts resources to the specific context; e.g. Acute neurosciences unit, rehab facility.
Process & Results • The evidence-based practice cycle (EBPC) was applied to determine best nutrition practice across the continuum of stroke care. The Canadian Stroke Strategy (CSS) identifies these phases of the continuum: • Primary Prevention • Pre-hospital/Hyper-acute • Acute/In-hospital • Stroke Rehabilitation, • Secondary Prevention • Community Care/Re-engagement • In the “asking and acquiring” steps of the EBPC, Dietitians of Canada’s Practice-Based Evidence in Nutrition (PEN) tool (3) was the first resource consulted. The results of several basic and advanced searches are listed in Table 1. Figures 3, 4 & 5 depict PEN’smethod of organizing and presenting information.

Practice Guidance Summary Ask Practice Question What nutrition strategies can prevent cardiovascular disease (CVD)? • Evidence Summaries • CVD • Dyslipidemia • CVD – Natural Health Products BackgroundOmega-3 fatty acids, fish oil, alpha-linolenic acid This document provides a grading of evidence for the effects of omega-3 fatty acids, fish oil, alpha-linolenic acid for a variety of conditions (e.g….stroke….). Key Practice Point Achieving and maintaining a healthy Body Mass Index (18.5-24.9), appropriate waist circumference (88 cm F; 102 m M) and waist-to-hip ratio (0.85 F; 0.90 M) can prevent CVD. • Tools & resources • Current Issues: The Health Benefits of Soy • Heart Healthy recipes • Heart and Stroke Foundation Evidence Apply References
Figure 5. Sample PEN results for search terms “stroke” AND “hypertension” 1) Follow DASH Diet Guidelines2) sodium intake to 2400 mg (100 mmol) per day 3) fibre intake to 25 to 30 grams per day especially foods rich in soluble fibre 4) A diet rich in potassium, calcium and magnesium is encouraged 5) …there is currently insufficient evidence to promote folic acid supplementation… 6) Maintain a healthy BMI and waist circumference 7) alcohol consumption to a maximum 2 drinks per day Practice Guidance Summary – excerpts from Prevention of Hypertension Practice Question Does an adult with hypertension, who adheres to healthy lifestyle practices … have better blood pressure control and therefore a lower risk or delayed incidence of stroke? Ask Evidence Summary A summary of the graded evidence supporting the prevention and treatment of hypertension. Background Information on hypertension, including causes, diagnosis, and management Key Practice Point Lifestyle modifications can reduce the use and hence cost of antihypertensive medications and should be continued in conjunction with drug therapy.

Process & Results (continued) Next, the CSS’s Best Practice document (1) and several key references listed in the CSS’s Best Practices and Standards Environmental Scan Report(2)were accessed via the Web and evaluated for their nutrition content (see Table 2 and Figure 6).

“Diet has an impact on a number of risk factors and can provide additional benefits to pharmacological interventions in people with vascular disease.” Figure 6. Sample content from selected key best practices documents Management of patients with stroke: Identification and management of dysphagia (SIGN) Canadian Best Practice Recommendations for Stroke Care: 2006 “All patients with stroke should have their swallow screened prior to initiating oral intake of fluids or food utilizing a simple valid reliable bedside testing protocol.” “Early and regular screenings of patients for undernutrition is important.” Best Practice Guidelines (Ontario) Clinical Guidelines for Stroke Rehabilitation & Recovery (Australia) “Determine feeding method based on swallowing assessment or monitoring. Implement safe diet texture and therapeutic diet.” Nutrition element from acute care guide, day 2 Section on secondary prevention
Summary • PEN has more than 120 up-to-date resources on stroke and cardiovascular disease risk factors (e.g., hypertension, dyslipidemia). • At present, most of PEN’s stroke resources apply to the prevention stage of the stroke care continuum. • New Critical Care and Dysphagia Knowledge Pathways soon will be added to PEN. They will provide information applicable to other stages in the continuum (e.g., acute care, rehabilitation). • Key resources recommended by the CSS (2)supplement PEN by providing nutrition standards across the continuum (4), dysphagia management guidelines (5), and templates for tools such as care paths (8). • This survey of PEN and CSS-recommended resources is ongoing.
Next steps The information gathered from these best practice resources will be applied to these three current projects: • Vancouver Acute Clinical/Care Redesign for Stroke (CMG 13 & 14) • Vancouver Coastal Regional Care Path for Stroke • Vancouver Coastal Regional Stroke/High Risk TIA Emergency Department Orders (section on diet and dysphagia screening)/
