Abstract
Background Improvement of communication among clinicians, seriously ill patients, and family members is a current national priority. Systematic measurement of conversational features in the natural clinical setting is an essential step for better understanding, distributing, and incentivizing high-quality serious illness communication. Uncertaintyis one important feature of the serious illness conversation which can be detected and measured using natural language processing. Objectives To use natural language processing to create a tool for measuring Uncertainty,and to use the resulting measurements for the exploration of associations with other important features of the conversation. Design This was a cross-sectional analysis of 354 transcripts of inpatient palliative care consultations from the Palliative Care Communication Research Initiative multisite cohort study. Setting/Subjects Hospitalized people with advanced cancer. Measurements We conceptualized a corpus of uncertainty language in the palliative care context by compiling uncertainty example terms present in context-relevant current literature. We accumulated synonyms and related words to this original list, and hedged the list to words with only uncertainty-related definitions. An adjudication team comprised of the full lab decided on the strongest of these terms. Using this final list, we explored subgroups of uncertainty language, and used natural language processing to detect instances of uncertainty and proportion of uncertainty within the PCCRI transcription dataset. Preliminary Results Manual comparison with 5 full transcripts showed no missed word instances and confirmed the program’s numbers for word counts. The use of natural language processing to detect the presence of uncertainty within textual data has resulted in variables which are currently being analyzed against relevant PCCRI survey data.
