Acupuncture-First Stepped Care Pathway (Routine Clinical Care)
ProcedureThis study does not assign or manipulate any intervention. Participants receive routine outpatient acupuncture care delivered within an existing acupuncture-first stepped care pathway.
The pathway represents standard clinical practice and includes individualized acupuncture treatment decisions made by the treating practitioner. Treatment frequency, duration (up to 8 visits per episode), and potential care escalation are determined solely by routine clinical judgment and patient response.
The study does not introduce additional procedures, randomization, comparison groups, or protocol-driven treatment modifications. Data are analyzed observationally from routine clinical documentation.
