There is limited research exploring the age-related difference in communication when describing pain experiences. This project aimed to identify key differences between adolescents’, young adults’ and adults’ (i) preferred communication method, (ii) language content and (iii) lexical amount and variety when discussing their persistent pain experience using chatbot technology.

An exploratory concurrent nested mixed-methods design using a comparative analysis.

Participants were recruited through a convenience sampling strategy from two tertiary multidisciplinary pain centres in Australia.

20 adolescents, 20 young adults and 20 adults completed a pain history assessment using the Dolores application. The inclusion criteria for this study were (i) persistent non-cancer pain for at least 3 months, (ii) 10 years of age and over and (iii) adequate expressive and receptive language skills to complete the required tasks in English, as determined by clinicians in the treating team.

Drawn, voice and typed responses provided by participants during the chatbot interaction were analysed using content analysis. Fisher’s exact tests and ² tests were used to examine differences between age groups. Strong effect size estimates generated from comparative analyses suggested that adolescents were the most likely age group to utilise drawing (p=0.153, Cramer’s V=0.268), preferred typing over speaking (p==0.007, Cramer’s V=0.433). Young adults used the greatest number and variety of words in response to chatbot questions including evaluative language (p=0.097, Cramer’s V=0.296). Adults tended to use more metaphors (p=0.085, Cramer’s V=0.305) and had a strong preference for speaking over typing (p=

The results of this study provide insights into age-related differences in communication and preferences when using technology to communicate about persistent pain. Future research exploring individualised age-related approaches to pain assessment, supported by the findings of this study, in comparison to current standardised assessments administered by clinicians are warranted.

Heart failure (HF) is a debilitating condition associated with high morbidity, mortality and healthcare resource use. Frailty in HF patients is associated with poorer outcomes, including increased morbidity, mortality and reduced quality of life (QoL). Nutritional disorders, such as malnutrition, are common in patients with HF and contribute to functional decline and increased mortality. The Meta-Analysis Global Group in Chronic HF (MAGGIC) risk score was developed to predict 1-year and 3-year hospitalization and mortality in patients with HF. This study aims to assess the added value of frailty, QoL and nutritional status to the MAGGIC risk score.

This prospective cohort study, conducted at a tertiary public hospital in southern Brazil, will include 316 patients with chronic HF who are followed up at the HF Outpatient Clinic. Frailty will be assessed using the Fried scale, health-related QoL will be assessed using the Minnesota Living with Heart Failure Questionnaire (MLHFQ) and nutritional status will be assessed using the Mini Nutritional Assessment. These variables will be incorporated into the MAGGIC risk score. Continuous variables with a normal distribution will be described as mean±SD, skewed variables as median±IQR and categorical variables as absolute and relative frequencies. Survival analysis will be performed using the Kaplan-Meier method with log-rank test comparisons. The prognostic value of frailty, its components, the MLHFQ score and nutritional status will be assessed by Cox regression, which will be adjusted for the MAGGIC risk score. Net Reclassification Improvement and Integrated Discrimination Improvement will assess the accuracy of the MAGGIC score when including frailty, MLHFQ and nutritional status. A p value
