Symptom-Based Assessment and Advice to Seek Medical Attention by Community Pharmacists: A Case Series

Community pharmacists increasingly serve as the first point of contact in primary healthcare as self-medication and over-the-counter (OTC) drug use expand, yet structured methods for symptom assessment and referral remain underdeveloped in Japan. This case series describes three patients in whom pharmacists used the LQQTSFA framework (Location, Quality, Quantity, Timing, Setting, Factors, Associated symptoms) to organize symptoms within current regulations and advise on seeking medical care. The cases involved chronic headache, laxative-induced diarrhea, and anxiety-related frequent consultations. In each case, pharmacists used structured questioning to clarify the clinical significance of the complaint, reframed patients' self-assessments, and cross-referenced findings with relevant clinical guidelines, leading to appropriate medical referrals that resulted in accurate physician diagnoses and clinical improvement. Across cases, a reproducible three-step pattern emerged: structuring the chief complaint, validating decisions with evidence-based references, and supporting behavioral change through follow-up. These cases suggest that structured symptom-based assessments by community pharmacists can promote early, safe, and rational healthcare-seeking without encroaching on diagnostic authority and may provide a practical foundation for educational and systemic implementation in Japan's evolving primary care.
