Incorporating evidence-based practice (EBP) is essential for enhancing clinical reasoning and judgment skills, especially for baccalaureate-prepared nurses. The PICOT framework is an essential tool that guides the formulation of clear, specific research questions. Using this approach, nurses can design studies, search for relevant literature, and evaluate the effectiveness of interventions or treatments. The PICOT framework emphasizes the improvement of healthcare outcomes and quality. Therefore, integrating EBP competencies into nursing curricula, particularly formulating PICOT questions, is crucial for developing these skills. Utilizing a PICOT template can help write healthcare-specific PICOTs, guide nurses in their search for quality evidence, and address community healthcare needs through evidence-based quality improvement. The PICOT process can be applied to develop a research question fundamental to evidence-based healthcare research. It ensures that the practice is informed by the most current and relevant findings, ultimately benefiting patients, healthcare systems, and nursing practice outcomes (Costanzo et al., 2023).
Defining a practice issue through a PICO(T) approach is a structured and systematic method of exploring and analyzing potential treatments for diseases such as cholecystitis. The PICO(T) framework helps to form a specific research question, which guides the study design and literature search for effective interventions or treatments. For instance, when considering the treatment of cholecystitis, a PICO(T)-formatted question may focus on the patient population with cholecystitis, a specific intervention or treatment that is being considered, a comparison to another treatment or no treatment, and the expected outcomes. The time frame is also critical, particularly when considering the progression and response to treating an acute condition such as cholecystitis.
Applying the PICO(T) approach to explore treatment options for cholecystitis helps frame a researchable question and ensures that the investigation is focused and relevant. PICO(T) facilitates a more targeted and effective exploration of clinical issues by breaking down the research question into specific components, leading to better-informed healthcare practices (Frandsen et al., 2020).
A possible PICOT question related to the treatment of cholecystitis could be structured as follows: “In adult patients with acute cholecystitis (P), how does early laparoscopic cholecystectomy (I) compare to delayed laparoscopic cholecystectomy (C) in reducing postoperative complications and hospital stay length (O) within the first 30 days post-surgery (T)?”. The question aims to clarify whether early intervention is more beneficial than a delayed approach in treating acute cholecystitis.
Using the PICOT approach, researchers can develop a well-structured research question to identify relevant studies, gather evidence, and conclude the impact. Studies suggest that early laparoscopic cholecystectomy (ELC) may result in shorter hospital stays and fewer postoperative complications in comparison to delayed laparoscopic cholecystectomy (DLC) for adult patients with acute cholecystitis. The PICO(T) approach can be used to structure research questions that compare ELC and DLC for treating cholecystitis (Kivivuori et al., 2023).
Using this framework, nurses can focus on specific aspects of patient care, promoting evidence-based practice. By clearly defining the intervention and the comparison, the PICO(T) approach allows for a direct comparison between two different methods of treating cholecystitis. The PICO(T) approach helps improve patient outcomes by identifying the most effective treatment method through rigorous research. Findings from studies that use this approach can inform and update clinical guidelines, ensuring that healthcare professionals follow the latest and most reliable evidence. It aids in efficient literature searches and clear comparisons between different treatments and ultimately contributes to improved patient outcomes and clinical guidelines (Shunmuga Sundaram et al., 2022).
To effectively answer a PICO(T) question, nurses should use high-quality evidence that addresses the question. Moreover, PubMed and Medline journal articles are some sources that could effectively define evidence-based PICOT questions. Systematic Reviews and meta-analysis studies synthesize findings from multiple RCTs and provide a comprehensive overview of the existing evidence. They are particularly useful for summarizing data and determining the overall effectiveness of an intervention.
