Abstract Background Sensorineural hearing loss (SNHL) is the most common auditory deficit in older adults and may lead to quality-of-life deterioration. However, few studies have been performed in low/middle-income countries, particularly in Latin America. This study aimed to assess the audiological benefit, quality of life, and factors associated with functional gain in elderly hearing aid users in the Fundación Santa Fe de Bogotá and UNIMEQ-ORL, two otology referral centers in Colombia. Design Pre-post study that included hearing aid users at the otology consult of the Fundación Santa Fe de Bogotá and UNIMEQ-ORL between June 2017 and December 2020. Glasgow Benefit Inventory (GBI) and Abbreviated Profile of Hearing Aid Benefit (APHAB) questionnaires were applied. Audiometric (0,5 kHz to 4 kHz) and speech audiometry results were collected. Results A total of 75 participants (132 ears) were included. The mean age was 70.73 years (SD: 12.66). The median hearing aid use in years was 0.71 (IQR: 0.64–0.90). Mean change in speech audiometry was − 26.53dB (95%CI: -28.09, -24.97; p < 0.001), in functional gain was − 21.75dB (-23.81, -19.68; p < 0.001). The mean changes in the APHAB domains were Ease of Communication: -37.85 (95%CI: -43.01; -32.7), Background Noise: -3.51 (-6.06; -0.95), and Aversiveness of Sounds: -6.9 (-2.04; 11.77). The GBI assessment of quality of life showed improvement in 100% of the population after the use of hearing aids. The number of years of hearing aids use was associated with functional gain. Conclusion The number of years of hearing aids use may impact on the functional gain in these populations. A significant clinical benefit was found in terms of quality of life, communication, and reverberation related to the use of hearing aids. Access to hearing aids should be granted, and public health strategies are needed to grant the access to hearing rehabilitation in these populations. Trial registration Fundación Santa Fe de Bogotá (Protocol Number: CCEI-12666-2020).
