ABSTRACT
The use of geriatric assessment (GA) by oncology specialists in Mexico is low. We aimed to explore factors associated with the evaluation of individual GA domains by Mexican oncology specialists. We performed an exploratory analysis of a sequential explanatory mixed-methods study consisting of an online cross-sectional survey of Mexican oncology specialists and follow-up interviews on the use of GA in cancer care. For each GA domain, we performed multivariable logistic regression analyses with the frequency of evaluation of the domains as the dependent variable (dichotomised as never/rarely/sometimes versus most of the time/always). A p-value <0.05 was considered significant. Qualitative data from the interviews were analysed inductively. Of 196 respondents, 62% were male, 50% were surgical oncologists, 51% took care of >10 patients per day and 61.7% had access to a geriatrician. Self-perceived confidence in managing common geriatric conditions was associated with the evaluation of specific GA domains. For instance, self-perceived confidence in managing dementia (OR 2.72; 95% CI 1.42-5.51, p = 0.008) was associated with cognition evaluation, while for evaluation of falls, self-perceived confidence in evaluation of falls (OR 6.31; 95% CI 3.19-12.46, p < 0.001) was significantly associated. Follow-up interviews showed quality and appropriateness of evaluations may not be ideal: in many cases, physicians do not use guideline-recommended tools. For example, evaluation of cognition is commonly performed through non-validated methods which may miss the detection of patients with an impairment in this domain, partly due to limitations in knowledge and time to use recommended tools. In conclusion, self-perceived confidence in evaluating and managing common situations in older adults was associated with the evaluation of GA domains as part of everyday practice in a sample of oncology specialists in Mexico. This analysis supports the use of educational interventions to boost knowledge and confidence regarding the proper use of validated GA tools among oncology specialists.
ABSTRACT
PURPOSE: There is limited information regarding the use of the geriatric assessment (GA) for older adults with cancer in developing countries. We aimed to describe geriatric oncology practice among Mexican oncology professionals and to identify barriers and facilitators for the implementation of GA into the routine care of older adults with cancer in Mexico. METHODS: We conducted an explanatory sequential mixed-methods study. We administered an online survey to cancer specialists in Mexico about the routine use of GA and barriers for its use. We then conducted online semistructured interviews with survey respondents selected by their use of GA, expanding on barriers and facilitators for performing GA. Descriptive statistical analyses were performed for quantitative data; qualitative data were analyzed inductively through thematic analysis. We developed joint displays to integrate quantitative/qualitative results. RESULTS: We obtained 196 survey responses: 37 physicians (18.9%) reported routinely performing a GA. Medical oncologists (P = .002) and physicians seeing ≤ 10 patients/day (P = .010) were more likely to use GA. The most frequent barriers for GA use were lack of qualified personnel (49%), limited knowledge (43.9%), and insufficient time (37.2%). In the interviews (n = 22), the limited availability of geriatricians was commonly mentioned. Respondents highlighted the lack of geriatric oncology knowledge among cancer specialists and geriatricians. Saturation of oncology services and a lack of effective referral pathways for GA were also common issues. Facilitators included availability of geriatricians, system/administrative facilitators, presence of a multidisciplinary team, and availability of geriatric oncology education. CONCLUSION: The routine use of geriatric oncology principles in Mexico is limited by the availability of qualified personnel and by insufficient knowledge. An educational intervention could improve the implementation of GA in cancer care.
