Literature Search

Conducting an exhaustive literature search is imperative for the PICOT question, which centers on the influence of nutritional and telehealth interventions on lung functioning and readmission rates in COPD (Chronic Obstructive Pulmonary Disease) patients within a 2 to 3-month timeframe. A thorough literature review allows healthcare professionals and researchers to comprehend existing evidence, identifying knowledge gaps in this domain. By scrutinizing published studies, systematic reviews, and meta-analyses, one can evaluate the efficacy of nutritional and telehealth interventions, their potential advantages, and possible adverse effects. A comprehensive literature search aids in bridging the gap between research and practice, ensuring healthcare interventions are grounded in the best available evidence (Al-Moamary et al., 2021).

Literature Search Strategy

A systematic approach was utilized to conduct an extensive literature search for the specified PICOT question. The search strategy incorporated relevant terms and Medical Subject Headings (MeSH) pertaining to COPD, nutritional interventions, telehealth interventions, lung functioning, and readmission. Databases such as PubMed, Embase, CINAHL, and the Cochrane Library were explored, and manual searches were conducted by reviewing reference lists of pertinent articles, systematic reviews, and meta-analyses. Following the initial search, 500 articles were retrieved. The inclusion of articles was determined by assessing the relevance of titles and abstracts to the PICOT question. This screening process narrowed down the included articles to 50, which underwent a full-text assessment for eligibility based on predetermined criteria (Ko et al., 2019).

After the full-text assessment, a final selection of 20 articles was made based on their adherence to inclusion criteria. These chosen articles, including randomized controlled trials (RCTs), systematic reviews, and meta-analyses, contributed to a comprehensive analysis of available evidence. Employing this systematic literature search strategy ensured a rigorous approach to identifying relevant studies while minimizing bias. The final selection of 20 articles formed a robust evidence base to effectively address the PICOT question.

The literature search strategy employed Boolean operators, combining terms such as “COPD AND nutritional interventions,” “COPD AND telehealth interventions,” “COPD AND lung functioning,” and “COPD AND readmission.” Using AND operators narrowed the search results, while OR operators broadened it. This systematic approach facilitated the retrieval of relevant articles, enabling a comprehensive analysis of the available evidence. This thorough literature review enhances understanding of the efficacy of nutritional and telehealth interventions in improving lung function and reducing readmission rates in COPD patients, guiding future clinical decisions and improving patient outcomes (Burton et al., 2022).

Analysis of Evidence

Critical appraisal was emphasized as a crucial step in evaluating the value of the 20 studies in clinical practice. Each study underwent meticulous examination to ascertain its evidence level, scrutinize the robustness of its methodology, and evaluate its potential applicability in real-world settings. By employing explicit and relevant criteria, the aim was to identify studies offering valuable insights with the potential to enhance patient outcomes. Subsequent stages of critical appraisal, namely evaluation and synthesis, delved into the collective findings of these studies, determining their overall impact on clinical practice. Through this comprehensive appraisal process, evidence that informed and enriched healthcare decision-making in COPD management was carefully selected and synthesized (Gaveikaite et al., 2019).

The analysis of the selected 20 articles encompassed a comprehensive assessment of various aspects. Articles were classified based on their nature, such as peer-reviewed, clinical guidelines, or best practice guidelines, to ascertain the level of evidence they provided. Each article’s aim, hypothesis, or research question underwent meticulous scrutiny to understand the study’s primary focus clearly. The research variables and data analysis techniques employed were thoroughly assessed to evaluate the validity and reliability of the studies. Critical appraisal of the evidence was conducted using appropriate tools, including the Strength of Recommendation Taxonomy (SORT), to assess the quality and strength of the evidence. Notable quotes from the articles were also extracted to highlight key insights and perspectives, enriching the appraisal process (Gaveikaite et al., 2019).

Organization of Literature According to the Main Themes

The selection of five main themes—Telehealth and Telemedicine in COPD Management, Digital Tools and COPD Management, COPD Self-Management and Rehabilitation, Personalized Medicine and COPD, and Readmission Rates and Healthcare Disparities in COPD—provides a structured approach to organizing the evidence and literature from the 20 selected articles. Categorizing articles into these themes facilitates the identification of commonalities and differences in research questions, methodologies, and findings across studies. Analyzing the evidence based on these themes aids in identifying trends, emerging interventions, and potential areas for future research in COPD management (Janjua et al., 2021).


Conducting a comprehensive literature search using a well-defined strategy is vital for addressing the PICOT question focused on the impact of nutritional and telehealth interventions on lung functioning and readmission rates in COPD patients within 2 to 3 months. By employing the suggested search terms, utilizing relevant databases, and conducting hand searches, researchers can ensure a thorough exploration of the available evidence. A comprehensive literature search enables evidence-based decision-making and improves COPD management and patient outcomes.
