Associations Between Hearing Loss and Health-Related Costs: A Retrospective Population-Based Cohort Study.

Purpose: Hearing loss (HL) is a leading cause of disability worldwide, but its health-related costs have been incompletely studied. Our objective was to examine the association between HL and direct health care costs and identify subgroups in which costs associated with HL are especially high.

Method: This was a retrospective population-based cohort study of adults treated in a universal health care system between April 2008 and March 2019.

Associations between hearing loss and clinical outcomes: population-based cohort study.

Background: Hearing loss (HL) is a leading cause of disability worldwide, but its clinical consequences and population burden have been incompletely studied.

Methods: We did a retrospective population-based cohort study of 4,724,646 adults residing in Alberta between April 1, 2004 and March 31, 2019, of whom 152,766 (3.2%) had HL identified using administrative health data.

Permanent bilateral sensory and neural hearing loss of children after neonatal intensive care because of extreme prematurity: a thirty-year study.

Objective: We present population-based, childhood prevalence rates of and neonatal risk factors for permanent hearing loss among extremely premature infants.

Methods: By using an inception-cohort, longitudinal study design for 1974-2003, we studied permanent hearing loss among 1279 survivors with gestational age of < or =28 weeks and birth weight of <1250 g (mortality rate: 42.7%; lost to follow-up monitoring: 4.
