ObjectiveWe estimated the association between the presence of pain and health care utilization among older adults residing in long-term care (LTC) facilities.Materials And MethodsUsing administrative health data maintained by the Saskatchewan ministry of health and time-to-event analyses with multivariable frailty models, we tested for differences in health care use (hospitalization, physician and specialist visits, and prescription drug dispensations) as a function of pain status among LTC residents after admission to an LTC. Specifically, we contrasted LTC residents with daily pain or less than daily pain but with moderate or severe intensity (ie, clinically significant pain group; CSP) to residents with no pain or nondaily mild pain (NP/NDMP group).ResultsOur cohort consisted of 24,870 Saskatchewan LTC residents between 2004 and 2015 with an average age of 85 years (63.2% female; 63.0% in urban facilities). Roughly one third had CSP at their LTC admission date. Health care use after admission to LTC was strongly associated with pain status, even after adjusting for residents' demographic and facility characteristics, prior comorbidities and health care utilization 1 year before the study index date. In any given quarter, compared with NP/NDMP residents, those with CSP had an increased risk of hospitalization, specialist visit, follow-up general practitioner visit, and onset of polypharmacy (ie, 3 or more medication classes).DiscussionTo our knowledge, this is the first large-scale project to examine the utilization of health care resources as a function of pain status among LTC facility residents. Improved pain management in LTC facilities could lead to reduced health care use.
