Background
Age increases the risk of emergency department [ED] visits. Health related quality of life (HRQoL) is often estimated as an outcome of ED visits, but it can be a risk factor of ED visits. This study aims to assess the association of HRQoL with time to first ED visit and/or frequent ED use in older adults during four-year period and if this association differs in 66–80 and 80+ age groups.
Methods
Data from the Swedish National Study on Aging and Care-Blekinge of wave 2007–2009 was used in combination with electronic health records on ED visits. The analytical sample included 673 participants of age 66 years and older with information on HRQoL. Cox proportional hazard model was used to assess the association between HRQoL and time to first ED visit. Logistic regression analysis was performed to estimate the association of HRQoL with frequent ED use.
Results
During the study period, 55.3% of older adults visited the ED and 28.8% had a frequent ED use. Poor physical HRQoL was independently associated with first ED visit both in total sample (p < 0.001) and in 66–80 (p < 0.001) and 80+ (p = 0.038) age groups. Poor mental HRQoL had no significant association with first ED visit and frequent ED use.
Conclusion
Findings suggest that poor physical HRQoL is associated with time to first ED visit in older adults. Therefore, physical HRQoL should be considered while planning interventions on the reduction of ED utilisation in older adults. Explanatory factors of frequent ED use may differ in age groups. Further studies are needed to identify associated factors of frequent ED visits in 80+ group.
