Evaluation of AI tool assisting primary healthcare physicians to diagnostic and treatment tasks
Primary healthcare (PHC) plays an important role in the healthcare system, yet the shortage of qualified primary healthcare physician (PHP) restricts the quality of diagnostic and treatment services provided by PHC institutions. The rapid development and prevalence of artificial intelligence (AI) offer a solution to this challenge. Existing research primarily focused on two themes: evaluating the performance of AI tools and investigating PHPs’ attitudes and use intention to such AI. There are three main modes used to evaluate the performance of AI tools: evaluation of single AI tool, comparison across different AI tools and comparison between AI tool and physicians. Confusion metrics and examination are two types of indicators primarily used to assess these products. PHPs generally hold positive attitudes and use intentions towards AI tools. According to the technology acceptance model, influential factors of PHPs’ attitudes and use intention can be categorised into usefulness and ease of use. Limitations and future research directions are also discussed in this article, which provides insights for future research and practice to improve AI tools assisting PHPs in diagnostic and treatment tasks and promote AI adoption in PHC.

The Impact of the “Inclusion of Rehabilitation Services in Basic Medical Insurance” Policy on the Utilization of Rehabilitation Services and Household Healthcare Expenditure Among Older Adults with Disabilities: Evidence from China
Background: The intersection of aging and disability is an important social issue. The rehabilitation system of older adults with disabilities is a complex social system including various social units. This study aims to investigate the impact of the “inclusion of rehabilitation services in basic medical insurance” (IRSMI) policy on the utilization of rehabilitation services and annual household healthcare expenditure among older adults with disabilities. Methods: Using the data of China Disabled Persons’ Condition Monitoring Survey (2009–2012), this study employed the difference-in-differences method to analyze the impact of IRSMI on rehabilitation services utilization and household healthcare expenditure, and further examined the differential effects of the policy on service utilization across subpopulations with different demographic characteristics, including gender, age, and disability severity. The Heckman two-stage model corrects for sample selection bias caused by the share of households with zero health expenditures. Event-study specification was applied to assess the validity of the parallel trends assumption in the DID framework. Baron & Kenny’s three-step method was used to explore the potential mediating mechanism. Results: (1) IRSMI significantly increased the likelihood of utilizing rehabilitation services among older adults with disabilities (OR = 1.349), but this kind of promotive effect mainly focus on males (OR = 1.530), middle-aged and older disabled individuals (OR = 1.423), and those with mild disabilities (OR = 1.444). (2) The implementation of IRSMI contributed to an approximately 20.3% increase in annual healthcare expenditures for households with older adults with disabilities ( = 0.185). (3) IRSMI significantly promoted the increase in household healthcare expenditures for high-income older adults with disabilities ( = 0.181), but had limited impact on low- and middle-income groups. (4) Rehabilitation services utilization played a mediating role in the relationship between IRSMI and household healthcare expenditure, with about 19.0% of the increase in annual household healthcare expenditures attributable to the enhanced utilization of rehabilitation services. Conclusions: In the complex social system of rehabilitation for older adults with disabilities, the IRSMI policy significantly increases the likelihood of rehabilitation services utilization and substantially raises annual household healthcare expenditures. However, the heterogeneous effects across gender, age, disability severity, and income levels reflect structural inequities embedded in the rehabilitation system, underscoring the need for adaptive and equity-oriented interventions.Open AccessThe Impact of the “Inclusion of Rehabilitation Services in Basic Medical Insurance” Policy on the Utilization of Rehabilitation Services and Household Healthcare Expenditure Among Older Adults with Disabilities: Evidence from China

The Moderating Role of Adverse Childhood Experiences in the Relationship Between Disability and Depression in Old Age: Evidence From China
Objective To investigate the association between adverse childhood experiences (ACEs) and depression in old age, and further examine the moderating role of ACEs on the relationship between later-life disability and depression.Methods This study utilizes data from the 2018 China Health and Retirement Longitudinal Study and the 2014 life course survey, employing the binary logistic regression to explore the relationship between ACEs and depression in old age, and applying a multiplicative interaction analysis method to explore the moderating effect of ACEs on the relationship between later-life disability and depression.Results The results show a positive association between ACEs and the likelihood of depression in old age (moderate relationship with parents: odds ratio [OR]=1.140, 95% confidence interval [CI] [1.006–1.293]; poor relationship with parents: OR=1.438, 95% CI [1.229– 1.684]; experiencing family stress events: OR=1.214, 95% CI [1.077–1.369]; living in an unsafe community: OR=1.284, 95% CI [1.049– 1.571]; sometimes or often being bullied by peers: OR=1.415, 95% CI [1.188–1.685]). Additionally, the association between later-life disability and depression is significantly weaker among older adults who reported sometimes or often being bullied by peers during childhood, compared to those without such experiences (OR=0.410, 95% CI [0.204–0.826]).Conclusion ACEs are positively associated with the likelihood of depression in old age, yet they may also serve a protective role in mental health during later-life severe adversity, such as disability. This protective effect may be attributed to post-traumatic psychological resilience, highlighting the importance of targeted interventions to enhance resilience in individuals exposed to trauma, as well as the integration of trauma-informed care into mental health services for older adults.
