New publication: PPV and NPV for continous and ordinal tests

Many diagnostic tests get dichotomized when calculating the positive and negative predictive value in a clinical setting - this is obviously a loss of information that could be avoided. In this paper, i extended the rationale of the ppv and npv to continous and ordinal scales, so you can get a more fine-grained assessment.

Using Bayes theorem to estimate positive and negative predictive values for continuously and ordinally scaled diagnostic tests

**Objectives:** Positive and negative predictive values (PPV/NPV) are frequently reported to put estimates of accuracy of a diagnostic test in clinical context and to obtain risk estimates for a given patient taking into account baseline prevalence …

Data: PROMIS Profile 29 general population data published

Today, we published PROMIS Profile 29 data from the general population in the UK, Germany and France at the Health Measures Dataverse. We hope that this data can be of use, e.

Predicting EQ-5D-5L crosswalk from the PROMIS-29 profile for the United Kingdom, France, and Germany

**Background:** EQ-5D health state utilities (HSU) are commonly used in health economics to compute quality-adjusted life years (QALYs). The EQ-5D, which is country-specific, can be derived directly or by mapping from self-reported health-related …

Patient-reported outcomes feedback report for knee arthroplasty patients should present selective information in a simple design - findings of a qualitative study

**Background:** Technical innovation to assess patient-reported outcomes (PROs) facilitates their implementation in clinical practice. In particular, mobile applications (apps) allow PROs to be assessed outside of the clinical setting. A patient’s …

Using subdomain-specific item sets affected PROMIS physical function scores differently in cardiology and rheumatology patients

Objectives: The Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) item bank has been developed to standardize patient-reported PF across medical fields. However, evidence of scoring equivalence across cardiology …

An initial psychometric evaluation of the German PROMIS v1.2 Physical Function item bank in patients with a wide range of health conditions

**Objectives:** To translate the PROMIS Physical Function (PF) item bank version 1.2 into German and to investigate psychometric properties of resulting full bank and seven derived short forms. **Design:** Cross-sectional psychometric study. …

Measurement invariance and general population reference values of the PROMIS Profile 29 in the UK, France and Germany

**Purpose:** Comparability of patient-reported outcome measures over different languages is essential to allow cross-national research. We investigate the comparability of the PROMIS Profile 29, a generic health-related quality of life measure, in …

Varying the item format improved the range of measurement in patient-reported outcome measures assessing physical function
