Incident opioid drug use among older adults with chronic obstructive pulmonary disease: a population-based study


Purpose — The purpose of this study was to describe the scope, pattern, and patient characteristics associated with incident opioid use among older adults with COPD.

Methods — This was a retrospective population-based cohort study using Ontario, Canada, healthcare administrative data. Study participants were individuals ages 66 years and older with physician-diagnosed COPD, identified using a validated algorithm, who were not receiving palliative care. We examined the incidence of oral opioid receipt between April 1, 2003 and March 31, 2012, as well as several patterns of incident opioid drug use.

Results — Among 107,109 community-dwelling and 16,207 long-term care resident older adults with COPD, 72,962 (68.1%) and 8811 (54.4%) received an incident opioid drug during the observation period, respectively. Among long-term care residents, multiple opioid dispensings (8.8%), dispensings for > 30 days duration (up to 19.8%), second dispensings (35%-43%), and early refills (24.2%) were observed. Incident opioid dispensing was also observed to occur during COPD exacerbations (6.9% among all long-term care residents; 18.1% among long-term care residents with frequent exacerbations). These same patterns of incident opioid use occurred among community-dwelling individuals, but with relatively lower frequencies.

Conclusions — New opioid use was high among older adults with COPD. Potential safety concerns are raised by the degree and pattern of new opioid use, but further studies are needed to evaluate if adverse events are associated with opioid drug use in this older and respiratory-vulnerable population.
