Step 4: Implement Useful Findings in Clinical Decision Making

Implementing useful findings is a deceptively complex process. This process occurs on multiple levels, including clinical decision making when caring for an individual patient, creation and implementation of policies on a facility- or community-wide level, and creation of evidence-based clinical practice guidelines designed to set standards of care on a national or global level. Clinical decision making is based on evidence of the intervention’s predictive power or efficacy, consideration of physical and psychosocial factors influencing effectiveness when applied to an individual patient, and knowledge of its direct cost or economic impact (van Rijswijk & Gray, 2012). For example, while a new drug may prove effective in a Phase 3 pivotal trial, its inclusion in a clinical practice guideline also must address its comparative effectiveness to existing agents with similar pharmacologic actions, its adverse side effects, and cost. The increased cost associated with a new drug may be justified if it proves more effective than existing agents or is associated with a lower risk of adverse side effects.

Understanding the Levels of Implementation

Implementing findings involves multiple layers, each crucial for ensuring that clinical decisions are not only based on evidence but also effectively tailored to the specific needs of patients. At the individual level, healthcare providers must consider the patient’s unique circumstances—both physical and psychosocial—when applying evidence-based practices. This personalized approach ensures that the implementation of findings leads to the most beneficial outcomes for the patient.

Evidence-Based Guidelines and Clinical Decision Making

The process of implementing findings from an evidence-based practice (EBP) document requires generating recommendations for clinical practice. The strength of these recommendations varies according to the strength of the underlying evidence. More than 60 taxonomies for grading the strength of practice recommendations are available, with widely used systems including the Strength of Recommendation for Treatment (SORT) scale, the US Preventative Services Task Force (USPSTF) recommendations, the Grading of Recommendations Assessment, Development, and Evaluation (GRADE) scales, the UK National Institute for Health and Care Excellence (NICE) scale, and the Scottish Intercollegiate Guideline Network (SIGN) taxonomy.

Key Taxonomies for Grading Practice Recommendations

One of the most influential scales is the GRADE scale, developed by a group of clinicians who ranked the strength of clinical recommendations based on current best evidence using a four-point scale. The highest grade indicates benefits that clearly outweigh the potential for harm, while the lowest grade suggests the intervention is likely to produce more harm than benefit. This scale helps clinicians navigate the complexities of applying evidence in real-world clinical settings, ensuring that their decisions are both informed and patient-centered.

The GRADE Scale in Practice

The GRADE scale is particularly valuable in scenarios where the balance between benefit and harm is not immediately clear. It provides a structured approach to evaluate the strength of evidence, allowing clinicians to make more informed decisions. For example, in situations where moderate evidence suggests a treatment could be beneficial but carries significant risks, the GRADE scale guides clinicians in weighing these factors to make the best possible decision for their patients.

Grade Scale:

1. High evidence: Additional research is unlikely to change confidence in the direction or magnitude of the effect size associated with a specific intervention.
2. Moderate evidence: Additional research may significantly influence the magnitude of the treatment effect.
3. Low evidence: New research may affect the direction and magnitude of the treatment effect.
4. Very low evidence: Insufficient evidence to determine treatment effect.

The US Preventive Services Task Force Scale

Another widely recognized ranking system is the US Preventive Services Task Force (USPSTF) scale, familiar to many APRNs practicing in North America. The USPSTF uses an ordinal scale with grades ranging from A to D and a fifth category labeled I. This scale links recommendations for practice to the direction, magnitude, and balance between benefit and harm, providing a clear framework for clinical decision making.

US Preventive Services Task Force Scale:

• Grade A: The service is recommended and supported by evidence of substantial benefit.
• Grade B: The action is recommended and supported by strong evidence of moderate benefit or moderate-level evidence suggesting moderate to substantial benefit.
• Grade C: Evidence suggests the service provides only a small benefit.
• Grade D: Evidence demonstrates no benefit from the service or potential harm outweighs the service.
• Grade I: Current evidence is insufficient to assess the balance between harm and benefit of the service.

Applying Evidence in Real-World Settings

When implementing useful findings in clinical decision making, it’s essential to recognize that evidence is just one piece of the puzzle. Clinicians must also consider the patient’s individual circumstances, including their preferences, health status, and social factors. This holistic approach ensures that the evidence is applied in a way that maximizes patient outcomes while minimizing potential risks.

Challenges in Implementation

One of the key challenges in implementing useful findings is the variability in evidence strength. Not all studies are created equal, and some may provide more reliable data than others. Clinicians must be adept at evaluating the quality of evidence and understanding how to apply it in practice. This requires ongoing education and a commitment to staying current with the latest research and guidelines.

The Role of Cost and Economic Impact

Another critical factor in clinical decision making is the economic impact of an intervention. Even if a treatment is proven effective, it may not be feasible to implement it on a wide scale if the cost is prohibitive. Clinicians must weigh the potential benefits of a treatment against its cost, considering both the direct expenses and the long-term economic implications for the patient and healthcare system.

Strategies for Successful Implementation

To successfully implement useful findings in clinical decision making, clinicians should:

1. Stay informed: Regularly update their knowledge with the latest research and guidelines.
2. Use structured frameworks: Utilize tools like the GRADE scale and USPSTF recommendations to evaluate evidence.
3. Consider the whole patient: Integrate evidence with patient preferences, health status, and social factors.
4. Evaluate cost-effectiveness: Balance the benefits of an intervention with its economic impact.

FAQs

Q1: What is the GRADE scale, and why is it important in clinical decision making? A1: The GRADE scale ranks the strength of clinical recommendations based on the best available evidence, helping clinicians make informed decisions that balance benefit and harm.

Q2: How does the US Preventive Services Task Force scale differ from the GRADE scale? A2: The USPSTF scale uses an ordinal ranking system (A to D and I) to guide clinical decisions, focusing on the balance between benefit and harm, similar to the GRADE scale but with a different categorization approach.

Q3: Why is considering the economic impact important in clinical decision making? A3: The economic impact of an intervention affects its feasibility and sustainability in clinical practice, making it essential to consider alongside its effectiveness.

Q4: How can clinicians stay updated on the latest evidence? A4: Clinicians can stay informed by regularly reviewing current research, attending professional development courses, and participating in clinical guideline updates.

Q5: What role do patient preferences play in implementing useful findings? A5: Patient preferences are crucial as they ensure that the chosen interventions align with the patient’s values, improving adherence and outcomes.

By following these guidelines and utilizing tools like the GRADE scale and USPSTF recommendations, clinicians can effectively implement useful findings in their clinical decision making, ultimately leading to better patient outcomes and more efficient healthcare practices.
