A Study of Antipsychotics in Individuals at Clinical High-risk for Psychosis (the SHARP-2 Study)

October 19, 2020 updated by: Tianhong ZHANG, Shanghai Mental Health Center

Real-world Effectiveness and Safety of Antipsychotics in Individuals at Clinical High-risk for Psychosis: Study Protocol for a Prospective Observational Study (SHARP-2)

The current study will improve knowledge on the effectiveness and safety of the use of antipsychotics at the prodromal phase and on factors influencing the outcome, and will eventually facilitate optimisation of individualised interventions for psychosis prevention and treatment.

Detailed Description

Help-seeking first-visit participants will be consecutively recruited. Every participant meeting the inclusion criteria will be fully informed of the study and asked to sign the written informed consent before enrolment.

Two senior nurses that will conduct the initial screenings were employed to collect all diagnostic and medication information from medical records on every follow-up visit. The four psychiatrists are qualified and well-trained and will conduct the SIPS/SOPS interview at baseline and follow-up.

The investigators will systematically record medication information. A model will be established to correlate antipsychotics with clinical and functional outcomes and demonstrate whether antipsychotics are useful and safe for preventing CHR individuals from converting to psychosis.

Based on experience from the sampling process in the SHARP-1 project, the investigators will recruit 600 participants at CHR. Considering a dropout rate of 20%, 510 cases of CHR will be followed up. According to the sample size calculation formula in superiority clinical trials of new drugs, the sample size of 600 cases is adequate for the demonstration of the effectiveness and safety of antipsychotics in CHR subjects.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Conversion to psychosis
Time Frame: 4 weeks
It will be determined using the criteria for the Presence of Psychotic Symptoms from SIPS. Specifically, the conversion will be defined by the presence of level 6 positive symptoms (the rating "6" refers to severe and psychotic symptoms) identified as either dangerous, disorganised, or occurring at least one hour a day on average, over four days a week for at least 16 hours.
4 weeks
Poor function
Time Frame: 4 weeks
It will be determined by GAF score. Specifically, poor function outcome is defined as the GAF score of less than 60 at the follow-up point.
4 weeks
