Measures of clinical response and mental state do not highlight differences between fluphenazine and amisulpride, risperidone, quetiapine or olanzapine. Largely measures of adverse effects are also unconvincing for substantive differences between fluphenazine and the newer drugs. All included trials carry a substantial risk of bias regarding reporting of adverse effects and this bias would have favoured the newer drugs. The four small short included studies do not provide much clear information about the relative merits or disadvantages of oral fluphenazine compared with newer atypical antipsychotics.

ObjectivesThis study establishes research priorities for medically not yet explained symptoms (MNYES), also known as persistent physical symptoms or medically unexplained symptoms, from the perspective of patients, caregivers and clinicians, in a priority setting partnership (PSP) following the James Lind Alliance (JLA) approach. Research into such symptoms in general has been poorly funded over the years and so far has been primarily researcher-led with minimal input from patients, caregivers and clinicians; and sometimes has been controversial.DesignJLA PSP method. The PSP termed these symptoms MNYES.MethodsThe study was conducted according to the JLA’s detailed methodology for conducting priority setting exercises. It involved five key stages: defining the appropriate term for the conditions under study by the PSP Steering Group; gathering questions on MNYES from patients, caregivers and clinicians in a publicly accessible survey; checking these research questions against existing evidence; interim prioritisation in a second survey; and a final multi-stakeholder consensus meeting to determine the top 10 unanswered research questions using the modified nominal group methodology.ResultsOver 700 responses from UK patients, caregivers and clinicians were identified in the two surveys and charities contributed from a broad range of medical specialties and primary care. The final top 10 unanswered research questions cover, among others: treatment strategies, personalisation of treatment, collaborative care pathways, training for clinicians and outcomes that matter to patients.InterpretationThe top 10 unanswered research questions are expected to generate much needed, relevant and impactful research into MNYES.
