Preoperative Opioid Use
Another warning sign for healthcare professionals is that patients with chronic pain may have factors associated with vulnerability. Women, who have a higher incidence of chronic pain syndrome, are at greater risk of developing postoperative chronic pain than men.
It has also been shown that preoperative opioid use leads to higher postoperative pain intensities for several days. This is a factor to consider, even though opioid consumption rates in France are far lower than those in the United States, where as much as 35% of patients use opioids preoperatively, said Frédéric Aubrun, head of the Anesthesia and Intensive Care Department and a pain management specialist at the Hospices Civils de Lyon in Lyon, France. Finally, significant literature indicates that psychological fragility is a risk factor for more intense acute pain and for POCP. “Patients with chronic pain frequently have depressive symptoms and anxiety,” said Lebuffe.
Involving General Practitioners
Because one responsibility of general practitioners is to identify patients with abnormal postoperative pain trajectories, the anesthesiologists at the press conference advocated for greater patient awareness and increased involvement of general practitioners in this identification process.
“If there is an expected duration of postoperative pain at varying intensities, since it all depends on the patient’s journey (the number of reoperations, history of opioid use, etc.), it is necessary to make patients aware that it is not normal to suffer long after a surgical intervention,” said Aubrun. In addition, it is important to “connect with primary care” and mobilize general practitioners to “detect patients sliding toward opioid overconsumption” and refer them to the appropriate care structure, he said.
Although dedicated facilities for this type of pain — like transitional pain clinics in Canada or northern Europe — do not exist in France, some hospitals, like Lille University Hospital, have established “intermediate consultations targeting patients with specific pain or chronicity characteristics. In these consultations, patients are systematically reviewed 4-6 weeks after surgery by the surgeon, who has been trained to identify neuropathic pain,” said Lebuffe. When a patient with such pain is identified, he or she is referred to an intermediate consultation and seen by a fellow anesthesiologist. The advantage of this consultation is that it is linked to a chronic pain structure. Consequently, frequent exchanges occur with the pain specialists involved in this structure, thus allowing for immediate optimization of pain treatments. The goal is to halt the process of central sensitization.
“We strongly believe in this type of transitional structure, even though it requires significant human resources,” said Lebuffe. He also called for a “societal reflection” on this issue because patients with chronic pain represent a significant cost to society, in terms of medications and work stoppages. Moreover, patients who are forced to stop working see their lives disrupted.
Managing POCP
When POCP with neuropathic characteristics has been diagnosed, specific treatments and techniques for chronic pain can be prescribed earlier than they currently are. “Systemic drug treatments for neuropathic POCP rely on various therapeutic classes (opioids, antidepressants, antiepileptics), which are not without side effects for the patient,” said Violaine D’ans, an anesthesiologist and pain management specialist at Polyclinique du Parc in Caen, France. Hence, the idea is to prescribe a minimal dose while providing the patient with techniques available to anesthesiologists. “We have a good range of management options that we use in perioperative pain management, and we have a role to play in radio- or CT-guided perinerve infiltrations, with continuous peripheral nerve blocks and possibly later with electrostimulation to help restore movement and avoid kinesiophobia.”
