Is older age a blessing for persons with painful conditions?

Pain experience in an aging adult population during a 10-year follow-up

OBJECTIVES

This 10-year follow-up study aimed to examine the persistence of SF-36 pain intensity and pain-related interference and to identify baseline factors that may relate to pain experience among community-dwelling aging adults.

METHODS

Questionnaire and clinical data on a total of 1,954 participants (mean age at baseline 63 years) were collected in 2002, 2005, 2008, and 2012. Based on pain reports, four pain intensity, pain interference (PIPI) groups were formed at each time point: PIPI group I: none to mild pain intensity and interference; II: moderate to extreme pain intensity, none to mild pain-related interference; III: None to mild pain intensity, moderate to extreme pain-related interference, IV: Moderate to extreme pain intensity and interference.

RESULTS

Participants with the most pain at baseline improved their pain situation the most during the follow-up. Higher BMI was associated with pain interference, and metabolic syndrome (MetS) and musculoskeletal diseases with both pain intensity and interference (p<0.05, statistically significant interaction between pain intensity and pain interference) at baseline. According to multivariate logistic regression analysis the following baseline characteristics were associated with remaining in PIPI group I throughout the follow-up: presence of musculoskeletal disease (OR 0.22 [95% CI 0.16-0.30]), high BMI (OR 0.93 [95% CI 0.90-0.97]), high household income (OR 1.46 [95% CI 1.07-1.98]), good childhood home environment (OR 1.03 [95% CI 1.00-1.05]).

CONCLUSIONS

Multiple factors may affect pain persistence in late adulthood with varying effect on pain intensity and pain-related interference. Pain situation of even those with most pain may be improved.

The prevalence and management of current daily pain among older home care clients

The aim of this cross-sectional study was to examine the prevalence and correlates of pharmacotherapy for current daily pain in older home care clients, focusing on analgesic type and potential contraindications to treatment. The sample included 2779 clients aged 65+years receiving services from Community Care Access Centres in Ontario during 1999-2001. Clients were assessed with the Resident Assessment Instrument-Home Care (RAI-HC). Prescription and over-the-counter (OTC) medications listed on the RAI-HC were used to categorize analgesic treatment into two groups (relative to no analgesic use): use of non-opioids (acetaminophen or non-steroidal anti-inflammatory drugs only); and, use of opioids alone or in combination with non-opioids. Associations between client characteristics and analgesic treatment among those in current daily pain were examined using multivariable multinomial logistic regression. Approximately 48% (n=1,329) of clients had daily pain and one-fifth (21.6%) of this group received no analgesic. In multivariable analyses, clients aged 75+years and those with congestive heart failure, diabetes, other disease-related contraindications, cognitive impairment and/or requiring an interpreter were significantly less likely to receive an opioid alone or in combination with a non-opioid. Clients with congestive heart failure and without a diagnosis of arthritis were significantly less likely to receive a non-opioid alone. A diagnosis of arthritis or cancer and use of nine or more medications were significantly associated with opioid use. The findings provide evidence of both rational prescribing practices and potential treatment bias in the pharmacotherapeutic management of daily pain in older home care clients.
