Background:
Conflicting international guidelines exist on the management of sore throat by antibiotics.
Objectives:
To assess with the Appraisal of Guidelines for Research and Evaluation II (AGREE) instrument the quality of guidelines for uncomplicated acute group A beta-haemolytic streptococcal (GABHS) sore-throat. To make a sensitivity analysis restricted to guidelines with a rigour of development score higher than 60% and to describe their recommendations on scores, tests, and antibiotic therapy, including their justification.
Methods:
A guideline literature review of acute GABHS sore throat, published between January 2000 and December 2019 in primary care and secondary care. The PubMed database, the Canadian Medical Association Infobase on Clinical Practice Guidelines and the International Network Guidelines were used. The quality of guidelines was assessed using the AGREE II instrument. The guidelines were classified into 2 categories: high-quality guidelines had to rate >60% for the rigour of development score, the others were classified as low-quality guidelines.
Results:
Significant heterogeneity between the 15 guidelines concerned the scores of the 6 assessment domains. Among them, 6 guidelines presented a score above 60% with regards to the rigor of development domain and used a systematic literature search method, citing meta-analyses of recent randomised clinical trials. Most of the 6 high-quality guidelines no longer recommended the systematic use of diagnostic scores and tests, nor antibiotic therapy to prevent acute rheumatic fever or loco-regional complications, except for high-risk patients.
Conclusion:
Major discrepancies emphasise the need for only high-quality guidelines, based on adequately assessed evidence. Restricted antibiotic prescriptions to severe cases or high-risk patients would avoid antibiotic resistance.

01:30Acute Pharyngitis
Acute pharyngitis is the inflammation of the back of the throat (pharynx), commonly resulting in a sore throat. It is a frequently encountered condition that prompts individuals to seek medical advice.
Classification
Acute pharyngitis can be categorized based on its underlying cause:

Etiology
It often arises from persistent viral or bacterial infections affecting sinuses and tonsils.
Additional contributing factors include inadequate dental hygiene, mouth breathing, recurring tonsillitis, allergic rhinitis, laryngopharyngeal reflux, and exposure to smoke, chemicals, and other environmental pollutants. Allergic reactions to pollen, mold, and pet dander, chronic cough, excessive voice usage,...

01:11Guidelines for Writing Outcome
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...
