Viral pharyngitis affects millions of people every year and causes symptoms such as sore throat, fever, and difficulty swallowing. The condition is often treated with antibiotics, even though they are not effective against viruses. This can lead to antibiotic resistance, unnecessary side effects, and extra costs for patients and healthcare systems (Thomas & Bomar, 2025). Using an evidence-based practice (EBP) approach helps ensure that treatment decisions are based on strong scientific findings instead of tradition. The Johns Hopkins Evidence-Based Practice (JHNEBP) model offers a clear way to find, assess, and apply research. This assessment aims to identify the best diagnostic and management practices for viral pharyngitis and to reduce unnecessary antibiotic prescriptions through credible evidence and structured implementation.
Viral pharyngitis presents a common challenge in patient care and shows an opportunity for EBP. Viral infection of the throat affects a large number of individuals worldwide. United States statistics report up to 10 million cases among children annually. Global estimates exceed a billion episodes each year (Thomas & Bomar, 2025). Persistent throat discomfort, cough, fever, sore throat, and difficulty swallowing often accompany viral pharyngitis. Misuse of antibiotics in such cases remains a pressing issue that EBP can address. Wrong dosage and excessive intake of antibiotics for viral pharyngitis lead to negative consequences.
Antibiotics lack effectiveness against viruses. The development of antibiotic resistance increases when antibiotics are used inappropriately. Adverse drug effects emerge in patients unnecessarily exposed. Financial costs rise for patients and healthcare systems. Clinical reasoning falters when treatment decisions rely on tradition rather than scientific evidence. Variation in practice contributes to inconsistent patient outcomes.
A standardized EBP model supports addressing antibiotic overuse effectively. Adoption of models like the JHNEBP or the Advancing Research and Clinical Practice through Close Collaboration (ARCC) leads to structured evaluation of current practice. A nurse can gather research evidence demonstrating antibiotic inefficacy in viral pharyngitis. Centers for Disease Control and Prevention (CDC) (2024) guideline recommendations reinforce that antibiotics should be avoided in uncomplicated viral throat infections. Evaluation of patient education strategies proves essential, helping patients understand viral illness duration and self-care expectations.
Monitoring outcomes through EBP model implementation reveals reductions in antibiotic prescriptions, fewer side effects, and improved patient satisfaction. Strong scientific grounding builds trust. Patients gain confidence when care decisions follow research findings. Nurses grow in clinical judgement and decision-making skills through engagement with credible evidence. Healthcare systems benefit from cost savings and the reduction of antibiotic resistance. Professional nursing practice strengthens with the integration of EBP frameworks. Combining prevalence data, evidence against unnecessary antibiotic use, and a structured EBP approach creates lasting positive change.
The JHNEBP Model offers a clear process for using research to improve patient care. This model is suitable for addressing viral pharyngitis because it allows nurses to use credible evidence to guide safe and effective care while avoiding unnecessary treatments such as antibiotics. The model has three main steps: Practice Question, Evidence, and Translation (Brunt & Morris, 2023). The first step, Practice Question, involves identifying a clear and focused question. In the case of viral pharyngitis, the nurse can ask questions. Defining the question helps in targeting the search for useful information. The team is selected, and responsibilities are shared among members to keep the process organized.
The second step, Evidence, focuses on gathering and appraising research. Scholarly articles, clinical guidelines, and trusted databases are used to find reliable information. For viral pharyngitis, evidence includes studies on symptom management, hydration, rest, and use of analgesics. The nurse evaluates each source for credibility, accuracy, and relevance. Evidence is then summarized to determine the most effective interventions. The third step, translation, involves applying the findings into practice. Recommendations are created based on the best available evidence.
For viral pharyngitis, this can include educating patients about supportive care, advising on the use of over-the-counter pain relief, and explaining why antibiotics are not effective for viral infections (Essack et al., 2023). Implementation plans are developed, along with strategies for evaluating outcomes. Thus, the JHNEBP model is appropriate for the clinical problem of determining and applying the best practice for managing viral pharyngitis. It encourages critical thinking, promotes the use of credible sources, and ensures that recommendations are both practical and safe. Using this model helps nurses provide care that improves patient comfort and avoids unnecessary treatments.
The JHNEBP model provides a clear process for finding and using research to improve care. The model begins with identifying a practice problem. In the case of viral pharyngitis, the major concerns include ensuring that patients receive an accurate diagnosis and effective management without unnecessary antibiotic use (Thomas & Bomar, 2025). A PICO(T) question was created to guide the search: In patients with symptoms of sore throat (P), does the use of rapid antigen detection testing (I), compared to clinical assessment alone (C), lead to more accurate diagnosis (O) within the first patient visit (T)? The next step involved gathering the best evidence. Databases such as CINAHL, PubMed, and Cochrane Library were searched using keywords like “viral pharyngitis,” “rapid antigen detection test,” and “diagnosis accuracy.” Filters were applied to focus on recent, peer-reviewed studies. Abstracts were reviewed to find research that was credible, relevant, and based on strong methodology.
The evidence was then critically appraised using the JHNEBP appraisal tools. Studies with clear sample descriptions, valid measurements, and consistent results were prioritized. Findings showed that rapid testing reduced unnecessary antibiotic prescriptions and improved accuracy in differentiating viral from bacterial cases. Challenges arose during the search process. Some articles focused on bacterial pharyngitis only, making it harder to find resources directly related to viral cases. Certain studies lacked sufficient sample sizes or had unclear methodology, which limited their reliability. Time constraints also made it difficult to review every potentially relevant article in depth. Finally, the evidence was synthesized, and recommendations were developed. Bakhit et al. (2024) supported the use of rapid antigen detection testing alongside clinical assessment. Applying the JHNEBP model ensured that the search was structured, comprehensive, and aimed at improving patient safety and quality of care for those with sore throat symptoms caused by viral pharyngitis.
Armitage et al., (2025) is credible as it was published in a peer-reviewed journal with high academic standards. The authors are qualified researchers, and the study included 376 participants under 16 years, ensuring reliable data. The information is current, relevant, and supported by clear statistical results, meeting the CRAAP criteria. The resource aligns with the PICOT question by addressing diagnostic accuracy in pharyngitis cases, comparing rapid tests to traditional methods. Findings such as PCR detection at 32·4% (122/376) and ID NOW sensitivity at 94·6% provide strong evidence. This source is stronger than others as it directly compares multiple diagnostic tools, offers precise numerical outcomes, and evaluates performance in real-world clinical settings.
Bakhit et al. (2024) is credible as it was published in a peer-reviewed journal and involved a systematic review of 63 studies. The authors used recognized databases such as PubMed, Embase, and Web of Science, which strengthens accuracy and reliability. The research is current, with searches completed in September 2022, and addresses the accuracy of Clinical Prediction Rules (CPRs) for diagnosing group A beta-haemolytic streptococci. The resource is relevant to the PICOT question because it compares diagnostic tools, helping differentiate bacterial from viral pharyngitis to prevent unnecessary antibiotic use. Evidence from head-to-head comparisons favoured the Centor CPR in adults over 18 years. This resource is better suited than others due to its broad evidence base and detailed CPR performance analysis.
The resource by Pavia and Plummer (2021) is credible because it is published in a peer-reviewed journal, written by qualified microbiology experts, and supported with recent references. The information is current, as it was published in 2021, and relevant to current diagnostic practices. The study clearly explains the principles, benefits, and limits of rapid antigen detection systems, making it directly applicable to the PICOT question on improving viral pharyngitis diagnosis. The article reports that antigen tests provide qualitative results quickly, at low cost, and with acceptable accuracy, which supports the goal of reducing unnecessary antibiotic use. Compared with other evidence, this resource offers a broader background, strong scientific explanation, and up-to-date analysis, making it better suited for guiding evidence-based clinical decisions.
Viral pharyngitis requires accurate diagnosis and effective management without unnecessary antibiotics. Using the JHNEBP model makes the search for evidence structured and reliable. The findings from credible studies support the use of rapid tests and patient education. Applying these recommendations improves patient comfort and reduces antibiotic resistance. Nurses gain stronger decision-making skills through evidence-based care. Patients benefit from safer, more effective treatment plans.
