Thoughts, emotions linked to opioid use in SCD

Results of a small study suggest that negative thoughts and emotions may increase opioid use in patients with sickle cell disease (SCD).

Researchers analyzed data from daily electronic patient diaries and found that patients were more likely to use short-acting opioids both when they experienced increased pain and “catastrophic” thoughts about that pain.

In fact, pain catastrophizing led to an increased use of short-acting opioids even when patients reported low levels of pain.

In addition, patients were more likely to use long-acting opioids when they experienced negative emotions.

The researchers noted that this study wasn’t designed to show that negative emotions or thinking cause an increase in opioid use. It was only designed to determine if there was an association.

Patrick Finan, PhD, of Johns Hopkins University School of Medicine in Baltimore, Maryland, and his colleagues described this study in The Journal of Pain.

The researchers enrolled 85 adults with SCD in this study. Patients were asked to fill out electronic diaries on a handheld personal computer every evening for 90 days.

The final analysis included only 45 patients, as these were the subjects who filled out the diary more than 25% of the time and had taken opioid pills at least once during the study period.

The patients had an average age of 37, and 71% were female. Most (93%) were African American, and 7% were classified as “other” or did not report their race.

At the start of the study, the patients reported on the dosage and type of opioid pill they were prescribed for long-acting and short-acting use. The daily diary collected data on the number of long-acting and short-acting opioid pills taken per day.

Patients rated their daily pain level on a scale of 0 to 10, with 0 being no pain and 10 being the worst pain imaginable.

Patients also rated positive emotions—including happy, calm, and cheerful—and negative emotions—including lonely, sad, anxious, and tired—on a scale of 0 to 10, with 0 being no emotion and 10 being the most intense emotion. The scores were converted to a 0-to-100 scale for the data analysis.

Separately, the researchers measured negative thinking using a Pain Catastrophizing Scale to rate “rumination,” or focus on pain, helplessness, and magnification of a current pain situation.

Results

Negative emotions were significantly associated with increased levels of long-acting opioids (P=0.001). The opioid dosage increased by 3.4 morphine milligram equivalents for every 10-point increase in negative emotions.

On the other hand, patients’ daily pain level, positive emotions, and negative thinking through catastrophizing did not significantly affect the amount of long-acting opioids taken.

“When someone is prescribed a daily, long-acting opioid, it is typically supposed to be at a fixed dose, and their pain level or emotions shouldn’t dictate whether they take more of this prescription or not,” Dr Finan said.

“Although we can’t prove misuse of the medication in our study, these data suggest that physicians and patients should clearly communicate about how patients should be taking their daily, long-acting opioids in order to minimize the potential for misuse.”

The researchers also found a significant association with short-acting opioid use and daily pain levels (P=0.006) as well as negative thinking by catastrophizing (P<0.001).

For every 10-point increase on the pain scale, the amount of short-acting opioids increased by 1.8 morphine milligram equivalents, and for every 10-point increase on the catastrophizing scale, pain medicine dosage increased by 2.5 morphine milligram equivalents.

Positive and negative emotions had no significant effect on the use of short-acting opioids.

“When pain was reported as low, sickle cell disease patients reported higher opioid use if they catastrophized, or focused their thinking on their pain, than if they didn’t,” Dr Finan said. “When pain levels were higher, negative thinking played less of a role in influencing opioid use.”

Dr Finan cautioned that studies such as this have some weaknesses, including the fact that self-reports are always uncertain, and the study only included 1 time point per day, although a person’s mood may fluctuate throughout the day based on life events and experiences.

For future studies, Dr Finan wants to use smartphone technology that can assess moods randomly throughout the day.

“Once we have a more intensive study to track mood variations throughout the day,” Dr Finan said, “then we can determine when it will be appropriate to send messages through text to intervene and affect patient behavior.”
