Assessing Functional Status in Geriatric Patients Attending Primary Healthcare Centers in Qassim Region, Saudi Arabia.

Background There is an increase in the geriatric population globally. Also, in Saudi Arabia, the elderly population is expected to become a significant proportion of the total population in future decades. To provide comprehensive care to the geriatric population, an assessment of their functional capacity is crucial. Objectives This study aims to assess functional capacity and identify factors associated with functional impairment among geriatric patients at primary healthcare centers (PHCCs) in Qassim Region, Saudi Arabia. Methods A cross-sectional study was conducted among 310 geriatric patients, including 155 males and 155 females, attending PHCCs. An interviewer-administered survey was conducted from June through October 2023. The interviews were conducted by trained physicians. To assess functional capacity, the Katz index of independence in activities of daily living (Katz ADL), the Lawton-Brody instrumental activities of daily living (Lawton-Brody IADL) scale, and Wudu (ablution) performance were used as assessment tools. The data was collected via a Google Form (Google LLC, California, USA) through an interviewer-administered questionnaire. The data was analyzed using SPSS Statistics version 21 (IBM Corp. Released 2012. IBM SPSS Statistics for Windows, Version 21.0. Armonk, NY: IBM Corp.). Results The mean age of the study participants was 71.9 (±7.02) years. A vast majority (91.9%) had chronic diseases. Among basic ADL, the respondents had a high level of independence in feeding (99.4%) and transferring (95.5%), while there was a low level of independence in bathing (13.2%). The analysis of the Lawton-Brody IADL showed independence in medication management (75.8%) and telephone use (72.9%); however, 54.8% of the study participants were unable to perform laundry-related activities independently. Around three-fourths (76.8%) of the study participants were able to perform Wudu independently. IADL independence was statistically significantly associated (p<0.001) with age, gender, education, and chronic diseases. The Katz ADL and Lawton-Brody IADL were correlated (r=0.607, p<0.0001), and Wudu performance was positively correlated with both indices (r=0.636, r=0.60, p<0.0001). Conclusions Assessing elderly functional capacity and addressing the risk factors of functional impairment is crucial to improving the quality of life in this segment of the population. Future research is needed to validate the use of Wudu performance as an assessment tool for functional capacity in the elderly population.
