| - | PPI is a coding system for questionnaires and self-completed surveys, that is provided by the All of Us Research Program. | + | Thank you for visiting the wiki! This page has moved to https://github.com/OHDSI/Vocabulary-v5.0/wiki/Vocab.-PPI. |
| - | + | ||
| - | **Source** | + | |
| - | All PPI information is manually obtained from the All of Us PPI Codebook. | + | |
| - | + | ||
| - | **Layout** | + | |
| - | PPI Questionnaire layout consists of Modules, Topics, Questions, and Answers. | + | |
| - | + | ||
| - | ^ PPI source type value ^ Description ^ | + | |
| - | | Module | A superior PPI entity representing a thematic set of topics, questions, and answers. \\ Currently, the following Modules are available: \\ 1) Consent PII\\ 2) Refresher Consent\\ 3) EHR Consent PII\\ 4) Family History\\ 5) Personal Medical History\\ 6) Healthcare Access & Utilization\\ 7) Lifestyle\\ 8) Overall Health\\ 9) The Basics\\ 10 PMI | | + | |
| - | | Topic | A semantic module section containing a thematic set of questions or answers | | + | |
| - | | Question | A multiple-choice or open-ended question requesting information | | + | |
| - | | Answer | An answer representing a defined statement or free text | | + | |
| - | + | ||
| - | **Concept Names** | + | |
| - | PPI source names are represented in a “display” field. However, to avoid concept name duplicates, modified PPI names have been made through the parsing of their source codes (values of a “pmi_code” field). Original “display” values were put into the CONCEPT_SYNONYM table. | + | |
| - | + | ||
| - | **Standard concept** | + | |
| - | If a PPI concept has a standard LOINC or SNOMED equivalent, it is considered to be Non-standard. | + | |
| - | If a PPI concept does not have a standard LOINC or SNOMED equivalent, it is considered to be Standard. | + | |
| - | + | ||
| - | **Domains and Concept Classes** | + | |
| - | + | ||
| - | ^ PPI source type value ^ Concept Class ^ Domain ^ | + | |
| - | | Module | Module | Observation | | + | |
| - | | Topic | Topic | Observation | | + | |
| - | | Question | Question | Observation | | + | |
| - | | Answer | Answer | Observation | | + | |
| - | | Protocol modification | PPI Modifier | Observation | | + | |
| - | | Physical measurement | Clinical Observation | Measurement | | + | |
| - | + | ||
| - | **Internal PPI relationships** | + | |
| - | A purpose of Internal PPI relationships is to build a PPI Hierarchy, which makes it easier to understand the relations between PPI concepts of different types. | + | |
| - | + | ||
| - | **External PPI relationships** | + | |
| - | A purpose of Internal of External PPI relationships is the following: | + | |
| - | to build PPI-LOINC-SNOMED hierarchical crosswalks based on the Internal PPI Hierarchy. | + | |
| - | to simplify s cross-analysis of patient-related information with a context of combined use of the PPI and such a coding system as either the LOINC or SNOMED. | + | |
| - | + | ||
| - | **Hierarchical crosswalks** | + | |
| - | The PPI Hierarchical crosswalks include only standard concepts. A PPI standard concept value depends on the existence of an equivalent mapping either to the SNOMED or LOINC. In turn, a standard SNOMED/LOINC equivalent, if present, takes place of a non-standard PPI concept in the Internal PPI Hierarchy and adopts all its ancestors and descendants. | + | |
