PICO(T) Questions and an Evidence-Based Approach
PICO(T) inquiries play a crucial role in formulating research questions for addressing chronic diseases. The “T” represents Time or Type of Study, while “PICO” encompasses Population, Intervention, Comparison, and Outcome. By specifying these components, clinicians and researchers can develop targeted and actionable study questions. Employing a PICO(T) structure ensures precision, relevance, and the ability to answer research questions with available data. Evaluation of research data and clinical knowledge remains pivotal in adopting an evidence-based approach to managing chronic diseases. Clinicians can improve patient outcomes by integrating the best available evidence into their practice through the use of PICO(T) questions and other tools (McClinton, 2022).
Exploring the Issue in Practice
Type-2 diabetes affects millions worldwide, necessitating lifelong treatment to prevent severe consequences like cardiovascular disease, renal disease, and blindness. Despite various treatment options, many individuals with type 2 diabetes struggle to achieve and maintain adequate glycemic control, leading to significant personal, familial, and healthcare system costs (Jia et al., 2019).
Healthcare professionals face challenges in managing patients with hyperglycemia who have inadequate glucose control despite current therapy techniques.
In adults with hyperglycemia (P), does adding telemedicine-based self-management training and assistance (I) compared to usual care (C) improve HbA1c levels (O) over 12 months (T)?

Addressing this issue underscores the importance of identifying and overcoming barriers to efficient diabetes care. Understanding factors contributing to poor glycemic control, including patient, healthcare system, and treatment-related variables, is crucial for developing tailored therapies to enhance diabetes outcomes. Patients can achieve and maintain optimal glycemic control through evidence-based strategies incorporating patient education, lifestyle modifications, and medication management, thereby improving their health (Pivari et al., 2019).
Benefits of the PICO(T) Approach
Employing the PICO(T) method is advantageous in addressing the practical problem of poor glycemic management among hyperglycemic patients. By defining essential components of the question, the PICO(T) framework facilitates the formulation of focused and relevant research questions. This approach enables academics and medical professionals to create precise, pertinent research questions based on accessible data, ensuring that the research topic is accurately defined and planned to address the relevant problem (McClinton, 2022).
Sources of Evidence
Several potential sources of evidence could effectively address the PICO(T) issue of incorporating telemedicine-based self-management training and assistance to enhance glucose control. Randomized controlled trials (RCTs) comparing the efficacy of telemedicine-based self-management education and assistance with standard treatment are one possible source of evidence. These studies can shed light on the effectiveness of telemedicine-based therapies for improving glycemic control and highlight any potential advantages or disadvantages of this approach (Zhang et al., 2022).
Systematic reviews and meta-analyses examining the effectiveness of telemedicine-based therapies for improving diabetes are other possible sources of evidence. These studies can summarize current data, identify knowledge gaps, and highlight areas requiring further investigation. Additionally, observational and cohort studies can provide insights into the clinical efficacy of telemedicine-based therapies, including their impact on patient outcomes and healthcare spending (Vounzoulaki et al., 2020).
Several factors or rationales should be considered when determining whether a research study or piece of evidence can address a PICO(T) issue. Firstly, the population, intervention, comparison, outcome, and timeframe specified by the PICO(T) question should be the specific focus of the research or evidence. High-quality research or evidence should also utilize appropriate data collection and analysis techniques and rigorous study designs (Yusra & Waluyo, 2022).
Additionally, considerations such as patient characteristics, comorbidities, and resource accessibility should be taken into account when assessing the applicability of the study or evidence in a clinical setting. The research or supporting data should also be current, reflecting the latest findings and recommended strategies for managing diabetes (Eberle & Stichling, 2021). Finally, it is essential to evaluate potential conflicts of interest, restrictions on research design or data collection, and the possibility of unmeasured variables influencing outcomes. By considering these criteria and justifications, researchers and clinicians can select the best sources of information to address PICO(T) issues and develop an evidence-based strategy for diabetes care (Artasensi et al., 2020).
Findings from Sources of Evidence
Randomized controlled trials, meta-analyses, observational studies, and cohort trials are relevant sources of information that can help address the healthcare problem of inadequate sugar control in individuals with hyperglycemia (Xie et al., 2020).
In a study conducted by Tefera et al. (2020), hyperglycemic patients attending an outpatient clinic in Ethiopia were evaluated for their diabetes health literacy and its association with glycemic management. The research found that patients with higher levels of diabetes literacy were more likely to achieve their desired diabetes level compared to those with lower diabetes literacy. Additionally, individuals with high adherence were more likely to attain desired glycemic control than those with poor adherence. Conversely, patients with comorbidities had a lower chance of achieving the desired level of glycemic control (Tefera et al., 2020).
In another study, Hurst et al. (2020) examined how knowledge and self-monitoring of diabetes related to glycemic control among Thais with type 2 diabetes mellitus. The research revealed a significant correlation between blood glucose control and diabetes management self-efficacy among Thai individuals with type 2 diabetes.
Credibility of Resources
Assessing the credibility of resources can be done using the CRAAP test, which evaluates Currency, Relevance, Authority, Accuracy, and Purpose. The two studies discussed were published in peer-reviewed journals, indicating they underwent rigorous evaluation by subject-matter experts. They also provide detailed accounts of their methodology to ensure the accuracy of their conclusions. Furthermore, both studies are recent, one published in 2020 and the other in 2019, demonstrating their relevance (Tefera et al., 2020). However, the reliability of these sources may be questioned as the studies were limited to specific populations and may not generalize to other groups. Nevertheless, including established psychometric tools and comprehensive questionnaires on diabetes health literacy enhances the credibility of the research. Despite limitations, both studies pass the test as reliable sources of data (Hurst et al., 2020).
Relevance of Findings
The two studies provide valuable insights into the relationship between type 2 diabetes patients’ health literacy and glycemic control. The research conducted in Ethiopia emphasizes the critical link between diabetes health literacy and glycemic control, highlighting the importance of health literacy in achieving desired outcomes (Tefera et al., 2020). The Thai study underscores the close relationship between diabetes management self-efficacy and glycemic control in individuals with type 2 diabetes (Hurst et al., 2020). These findings have significant implications for the PICO(T) topic of enhancing glycemic control in type 2 diabetic patients. They suggest that treatments focusing on improving health literacy, adherence, and self-efficacy may enhance glycemic control. Particularly, the strong
In summary, the findings from both trials suggest the potential benefits of patient education, self-management skills, and interventions to enhance self-efficacy in improving glycemic control and reducing complications associated with chronic diabetes. These programs should not only focus on increasing patients’ awareness of diabetes but also on boosting their sense of self-efficacy and adherence to medication. Healthcare professionals and policymakers should take these results into consideration when making decisions regarding diabetes treatment to improve patient outcomes.
