1 Introduction This document describes the CDISC implementation of the Pain questionnaire, a standard public domain questionnaire administered on a CRF that is typically used in clinical trials to measure pain response. Please refer to the CDISC Pain Standards User Guide (http://www.cdisc.org/therapeutic) for information on developing this data standard by the sponsor, Analgesic Clinical Trial Translations, Innovations, Opportunities, and Networks (ACTTION) and their working group, STandardized ANalgesic DAtabase for Research, Discovery, and Submissions (STANDARDS). The Pain concept preceded the CDISC CDASH CRF standards and has no standard CRF, based on its public domain status. CDASH standard CRFs may be developed in the future. The representation of data collected for this questionnaire is based on the Study Data Tabulation Model Implementation Guide (SDTMIG) QS domain table (SDTMIG), which can be found at the CDISC website at http://www.cdisc.org/sdtm. These implementation details for this specific questionnaire are meant to be used in conjunction with the SDTMIG, but are recorded separately since this questionnaire may be used in many different therapeutic area implementations. All questionnaire documentation can be found on the CDISC web site (http://www.cdisc.org/content2909). The CDISC Intellectual Property Policy can be found in the ABOUT CDISC/Bylaws & Policies section of the web site. 1.1 Representations and Warranties, Limitations of Liability, and Disclaimers This document is a supplement to the Study Data Tabulation Model Implementation Guide for Human Clinical Trials and is covered under Appendix F of that document, which describes representations, warranties, limitations of liability, and disclaimers.

2 Copyright Status This instrument is in the public domain. CDISC has included the general Pain concepts as part of CDISC Data Standards. This means that CDISC developed QSCAT, QSTESTCD and QSTEST for the questions based on the actual question text on the questionnaire. There may be many versions of this questionnaire in the public domain. CDISC has chosen to use this version as the data standard. The CDISC documentation of this instrument consists of: (1) controlled terminology, (2) standard database structure with examples and (3) case report forms annotated with the CDISC SDTMIG submission values are not available, due to the general Pain concepts not having a published standard CRF. Note: CDISC controlled terminology is maintained by NCI EVS. The most recent version should be accessed through the CDISC website. (http://www.cdisc.org/terminology) CDISC has developed this documentation at no cost to users of the instrument.

3 The QS Domain Model 3.1 Assumptions for the Pain Questionnaire Domain Model All assumptions for the QS domain from the SDTMIG apply for this supplemental implementation guide including those referenced in the CDISC notes. Additionally, the following assumptions apply to Pain : 1. The questions relevant to measurement of Pain are in the public domain and routinely used in a variety of Pain/Analgesic condition studies. The Pain measures are a rating of the relief of pain at specified time points. Visual analog or numeric rating scales used within a questionnaire with a range of text and numeric values are indicated in the SUPPQS domain with: QNAM=RNGTXTLO QNAM=RNGTXTHI QNAM=RNGVALLO QNAM=RNGVALHI By storing this information in SUPPQS, it is available for interpretation purposes. The SDS QS Team is researching alternative methods to handle this data, but until a new method is identified, this will be the agreed approach. Pain is usually measured in a verbal rating scale with a categorical list of text and numeric values that are indicated in the SUPPQS domain as described above. For a verbal scale, the subject selects a descriptive phrase. Since the design of Pain/Analgesic studies is continually evolving, often using different numeric values for the same text values across drug projects and studies, the STANDARDS Working Group realized that further terminology standardization in the Pain Therapeutic Area will be needed on an ongoing basis. Such additional future terminology standards, where applicable, may be addressed by ACTTION in subsequent versions. CDISC and the ACTTION working group have suggested draft terminology for these pain scales. At the current time, standardization of these terms for data pooling will need to be performed in analysis datasets using the CDISC Analysis Data Model (ADaM) and the Statistical Analysis Plan (SAP). 2. Pain assessments include a variety of types of measurements beyond relief in general. This is normally specified in the question being asked as Rate your pain relief. Individual Pain test codes and test names are defined for each of these Pain questions. Pain Average Pain Least Pain Worst Pain 2012 Clinical Data Interchange Standards Consortium, Inc. All rights reserved Page 5
Minimum Pain Maximum Pain 3. The following Pain measures are also used in specific pain condition studies and are illustrated in the example below. This is normally specified in individual questions. Individual Pain test codes and test names are defined for each of these pain relief questions. Starting Pain at Least 1/2 Gone Time to Perceptible Pain Was there Perceptible Pain Time to Meaningful Pain Was there Meaningful Pain 4. The location of pain relief is populated in QSLOC with CDISC Location Terminology indicating the anatomical location when specified in a study. If multiple pain relief locations are specified separately at the same time point, separate records will be created for each anatomical location in order to enable analysis for each location. When a study is conducted for a specific type of overall pain (.ex Fibromyalgia, Diabetic Neuropathy, etc.), the Medical History MHTERM for the MHCAT=PRIMARY DIAGNOSIS will indicate the type and time reference of pain historically observed. Refer to the Pain Standards User Guide (http://www.cdisc.org/therapeutic) for a data example of this MH record. If this is not captured, the Trial Summary domain would contain an indication parameter to define the pain being investigated in the study. 1. Pain is relief at the time the question is asked. All the other test names above imply a period of time. For example, Least Pain in the last week could easily have a different value from Least Pain in the last year. This period of time should be clear in the data collection and, if it is, should be represented in the SDTM dataset as described below. The time period of evaluation of Pain is populated in the QSEVLINT field in ISO 8601 format when the evaluation interval can be precisely described as a duration as shown in examples a-c below. Specific points in time should use the QSDTC field as shown in example d. In cases where the evaluation interval cannot be precisely described as an ISO 8601 duration, the evaluation period should be represented using the Supplemental Qualifier EVLINTTX, as shown in examples e-g. In cases that are related to protocol-specified points in time, the QSTPT variable may be used as in example h. a. over last 24 hours QSEVLINT = -PT24H b. over last hour QSEVLINT = -PT1H c. over last week QSEVLINT = -P1W 2012 Clinical Data Interchange Standards Consortium, Inc. All rights reserved Page 6
d. right now QNAM=EVLINTTX QVAL= right now e. over the last night s sleep QNAM=EVLINTTX QVAL= Over last Night s Sleep f. Starting Pain is measured from the beginning of treatment QNAM=EVLINTTX QVAL= Pain from beginning of treatment g. since last medication: - QNAM=EVLINTTX QVAL= Since last medication h. At use of rescue medication this type of CRF is usually supplied at non-scheduled time point when rescue medication is administered to assist in relieving pain. The CDISC visit field is populated with VISIT= study design VISIT value QSTPT= Rescue Medication as a planned time point 5. Frequency/Timing of Pain measures captured in a study is normally included in the protocol s table of time and events (e.g., Hourly, Multiple times per day, periodic, etc.) For example, a rating of pain relief in the past 24 hours could be administered every day or once each week, and a rating of average pain relief in the past 7 days could be administered every week or once a month. The CDISC Trial Design model represents information about the protocol as parameters in the Trial Summary domain, and a terminology request is being submitted for the TSPARMCD=RATNGFRQ and TSPARM=Frequency of Rating Capture to address this need. CDISC will announce an alternative if one is determined to be necessary upon further investigation. 6. Activity during Pain measurements is populated in SUPPQS with QNAM=MOVETYP and QLABEL = values provided below. A. Not specified B. At rest C. With Movement 7. The evaluator of the questionnaire is stored in QSEVAL and for the Pain the Subject provides the evaluation of pain relief. 8. Terminology A. Requests for controlled terminology for the QSCAT, QSTESTCD, QSTEST and QSMETHOD variables are being submitted through the CDISC controlled terminology process. Controlled terminology is still under development for the Pain data standards, thus some values in the examples are not CDISC controlled terms. Verify demonstrated terminology against current standards before adopting it. B. Controlled terminology code lists are being submitted for the VERBAL RATING SCALE 6-POINT value lists as displayed in section 4. C. The specific mapping strategy for Pain using standard QS fields is described in Section 4: Mapping Strategy for the following required fields. 2012 Clinical Data Interchange Standards Consortium, Inc.

Section 4 provides guidance on how the result and category variables in the QS domain need to be populated for a questionnaire. (ex. QSORRES, QSORRESU, QSSTRESC, QSSTRESN, QSSTRESU, QSCAT and QSMETHOD) If a result variable is not included in the table for a questionnaire, it should not be populated. D. SUPPQS is used for additional data standardization with those data items listed in the Appendix C: Supplemental Qualifiers. 3.2 Examples for Pain Domain Model Example 1: 5-Point Verbal Rating Scale This example shows data from one subject collected at three visits for a Back Pain 5-Point Rating Scale questionnaire evaluated over the past 24 hours. The example uses standard controlled terminology for QSTESTCD, QSTEST, QSCAT, QSMETHOD and QSLOC for the Pain scale. QSSTRESN will be set to the standard numeric value and then converted into QSSTRESC. SUPPQS is populated with the data range text and numeric values. Rows 1-3: qs.xpt Represent 3 visit values of Back Pain ratings for USUBJID= from a Pain 5-Point Rating Scale Form. All original results are represented in QSORRES, which is then transformed into a Standard Numeric rating QSSTRESN, which is then also copied to a standard character value in QSSTRESC.
