Electronic Patient-Reported Outcome Measures Evaluating Cancer Symptoms: A Systematic Review

This systematic review aims to evaluate the psychometric properties and the methodologic quality of studies describing smartphone-, tablet- or computer-based questionnaires for Patient-Reported Outcome Measures (PROM) evaluating symptoms in oncology and hematology patients.

A literature search was conducted in PubMed, Scopus, Cochrane, Cinahl, Cuiden, Lilacs, and PsycINFO. Criteria for inclusion were (i) primary studies evaluating scales for symptoms assessment, (ii) developed in adult population (>18 years) with an oncology or hematology malignancy diagnosis, (iii) validations tested via phone or computer, and (iv) describing at least one psychometric property. The exclusion criteria were (i) tools diagnosing any type of cancer and (ii) case series, surveys, and audits. The outcome variables were internal consistency, test-retest reliability, measurement error, content validity, structural validity, hypothesis testing, cross-cultural validity, and responsiveness. For the evaluation of the quality of methodology, the COnsensus-based Standards for the selection of health Measurement INstruments (COSMIN) checklist was used.

The present study gathered five tools in 12 articles to evaluate cancer symptoms through smartphone, tablet, or computer format. Although four were generic, one was specific for breast cancer. Although none of the tools had been fully validated, some of the items of the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events (PRO-CTCAE) were successfully tested for content, reliability, construct validity, and responsiveness.

Our results can guide professionals choosing symptoms assessment instruments when performing telepractice, and they raise awareness of using with precaution scales not intended for remote use.
