Oral health-related quality of life among elderly patients visiting special clinics in public hospitals in Delhi, India: A cross-sectional study

Background: Oral health is recognized as an integral component of general health, and poor oral health is reflected in general health and quality of life (QoL). India has seen a profound shift in the elderly population and is currently home to 103.9 million elders. General Oral Health Assessment Index (GOHAI) is a self-reported oral health assessment index used in elderly population and has been tested in multiple countries. Objective: The study aimed to assess the oral health-related QoL (OHRQoL) using GOHAI and various factors affecting it, among elderly patients visiting special Sunday geriatric clinics at Delhi public hospitals. Methods: A cross-sectional study was conducted among four purposively selected special geriatric public clinics in Delhi, India, and a convenience sample of 145 elderly patients was obtained. OHRQoL was measured using a prevalidated instrument (GOHAI) along with other variables (sociodemographic factors, self-perceived oral health, utilization of medical/dental services, dental problems in the past 12 months, and prosthetic status/need). Statistical analysis was done using Statistical Package for the Social Sciences software version 21, and descriptive results were obtained. Results: The sample consisted of 66 males (45.5%) and 79 females (55.5%), and around 58% (n = 84) of the participants were illiterate. Around 39% (n = 57) of the elderly had never visited a dentist and 48% (n = 69) were financially dependent (no income) on others. The mean GOHAI score for the population was 26.69 + 4.44 (median = 25, interquartile range = 23-27). GOHAI score was compared for age, oral hygiene practices, dental problems in the past 12 months, self-reported oral health, and prosthetic need, and a statistically significant difference was observed. Conclusions: The current study assessed GOHAI score and highlighted important determinants of OHRQoL in elderly population visiting the special clinics in Delhi. Thus, OHRQoL should be considered as a surrogate measure to clinical oral examination.
