Computer system and method for training certifying or monitoring human clinical raters
A method and system are disclosed for computerized training, monitoring, certification or re-certification of human raters in clinical trials. The invention provides an interactive computerized interview that can be compared scores obtained by human raters to monitor and train clinical raters on a continuing basis in order to reduce rater drift and variance during clinical trials. Remediation can be automatically flagged or provided to improve a deviating rater's performance. Computerized assessment of symptom severity is provided without the need for human clinical raters. The system and method enable screening of prospective patients for inclusion or exclusion from a clinical trial by automatically obtaining computerized ratings of symptom severity.
1. A computerized method for improving a clinical research rater's performance or reducing drift in the evaluation of a clinical research trial subject's reaction to a drug, comprising the steps of:
(a) posing a question to a subject via a computerized system;
(b) receiving a first answer to the question via the computerized system, wherein the subject directly inputs the first answer to the question into the computerized system;
(c) receiving a second answer to the question via the computerized system, wherein the clinical research rater directly inputs the second answer to the question into the computerized system, wherein the second answer is based on information the clinical research rater obtained via the rater's clinical interview of the subject; and
(d) informing the clinical research rater of any discrepancy between the first and second answers, wherein the discrepancy is determined via the computerized system.
2. The method according to claim 1 , wherein the question is from a clinical scale for a psychiatric illness.
3. The method according to claim 2 , wherein the scale is selected from the group consisting of: the Young Mania Rating Scale (YMRS); the Montgomery-Asberg Depression Rating Scale (MADRS); the Hamilton Depression Scale (HAMD); the Schedule for Affective Disorders and Schizophrenia, Current symptom version mania Rating Scale (SADS-C); an Additional Psychiatry Scale; a Geriatric/Cognitive Scale; an Other Cognitive Assessment; a Non-CNS Scale; or a member of the APA group of scales.
4. The method according to claim 1 , wherein the question is presented by visual, audio, or multimedia display.
5. The method according to claim 1 , wherein the subject's input is obtained within 24 hours after the clinical rater's input.
6. The method according to claim 1 , wherein the rater input and the subject's input are obtained during the same clinic visit.
7. A computerized method for improving a clinical research rater's performance or reducing drift in the evaluation of a clinical research trial subject's reaction to a drug, comprising the steps of:
(a) posing a plurality of questions to a subject via a computerized system;
(b) receiving first answers to the plurality of questions via the computerized system, wherein the subject directly inputs the first answers to the plurality of questions into the computerized system;
(c) receiving second answers to the plurality of questions via the computerized system, wherein the clinical research rater directly inputs the second answers to the plurality of questions into the computerized system, wherein the second answers are based on information the clinical research rater obtained via the rater's clinical interview of the subject; and
(d) informing the clinical research rater of any discrepancy between the first and second answers, wherein the discrepancy is determined via the computerized system.
8. The method according to claim 7 , wherein the question is from a clinical scale for a psychiatric illness.
9. The method according to claim 8 , wherein the scale is selected from the group consisting of: the Young Mania Rating Scale (YMRS); the Montgomery-Asberg Depression Rating Scale (MADRS); the Hamilton Depression Scale (HAMD); the Schedule for Affective Disorders and Schizophrenia, Current symptom version mania Rating Scale (SADS-C); an Additional Psychiatry Scale; a Geriatric/Cognitive Scale; an Other Cognitive Assessment; a Non-CNS Scale; or a member of the APA group of scales.
10. The method according to claim 7 , wherein the questions are presented by visual, audio, or multimedia display.
11. The method according to claim 7 , wherein the subject's input is received by means of a keyboard, a pointing device, a touch-screen device, or voice response.
12. The method according to claim 7 , wherein the discrepancy is determined via the computerized system within 24 hours after the clinical interview.
13. The method according to claim 7 , wherein the rater input and the subject's input are obtained during the same clinic visit.
14. A system for obtaining the subject's input according to claim 7 , comprising:
an output device configured to present selected questions to the subject;
an input device configured to accept inputs from the subject; and
one or more computers configured to present selected questions to the subject by means of the output device, receive inputs from the subject by means of the input device, and determine the computerized severity score based on the inputs received from the subject in accordance with the rating scale.
