Tapering patients on long-term opioid therapy results in more emergency department visits and hospitalizations, according to a large new study that found reduced opioid use was particularly disruptive to the healthcare of pain patients with diabetes and high blood pressure.

The study by researchers at University of California Davis is the latest to document the “unintended negative consequences” of policies that limit opioid prescribing. A previous study by the same research team found that tapering raises the risk of an overdose and mental health crisis.

In their latest study, UC Davis researchers analyzed health data for over 113,000 patients who were on opioid therapy for at least 12 months, comparing those who were not tapered to those who had their dose reduced by 15% or more.

Their findings, published in JAMA Network Open, showed that tapering significantly increased hospitalizations and ED visits, while at the same time reducing the number of primary care (PC) visits. Researchers think the latter is at least partially due to “ruptures in relationships” with primary care providers (PCPs) due to patient dissatisfaction with tapering.

Opioid tapering was also associated with a significant reduction in patients taking medication for hypertension or diabetes – even though their blood pressure and blood sugar levels rose when their opioid doses were reduced.

“Tapering may be associated with reduced medication adherence due to an increased patient focus on managing pain and psychological distress due to the taper, disruption in PC due to more frequent ED visits and hospitalizations, or fracture of the PCP-patient relationship,” wrote lead author Elizabeth Magnan, MD, a family medicine physician at UC Davis Medical Center.

“Although cautious interpretation is warranted, these outcomes may represent unintended negative consequences of opioid tapering in patients who were prescribed previously stable doses.” 

Opioid prescribing has fallen dramatically in the U.S. over the past decade, particularly after the release of the CDC’s 2016 opioid guideline. Although millions of patients were affected by the guideline’s recommendations, few efforts were made at the federal level to see what happened to patients who had their opioid doses reduced or even stopped.

A recent study found the number of cancer patients seeking treatment for pain in emergency departments has doubled. Of the 35 million ED visits made by cancer patients, over half were deemed preventable – meaning the visits could have been avoided if the patient has received proper care earlier.
