Dying With Unrelieved Pain—Prescription of Opioids Is Not Enough

Abstract

Context. Fear of pain resonates with most people, in particular, in relation to dying. Despite this, there are still people dying with unrelieved pain.Objectives. We quantified the risk, and investigated risk factors, for dying with unrelieved pain in a nationwide observational cohort study.Methods. Using data from Swedish Register of Palliative Care, we analyzed 161,762 expected deaths during 2011e2015. The investigated risk factors included cause of death, place of death, absence of an end-of-life (EoL) conversation, and lack of contact with pain management expertise. Modified Poisson regression models were fitted to estimate risk ratios (RRs) and 95% confidence intervals (CIs) for dying with unrelieved pain.Results. Unrelieved pain during the final week of life was reported for 25% of the patients with pain, despite prescription of opioids PRN in 97% of cases. Unrelieved pain was common both among patients dying of cancer and of nonmalignant chronic diseases. Statistically significant risk factors for unrelieved pain included hospital death (RR ¼ 1.84, 95% CI 1.79e1.88) compared with dying in specialist palliative care, absence of an EoL conversation (RR ¼ 1.42, 95% CI 1.38e1.45), and dying of cancer in the bones (RR ¼ 1.13, 95% CI 1.08e1.18) or lung (RR ¼ 1.10, 95% CI 1.06e1.13) compared with nonmalignant causes.Conclusion. Despite almost complete prescription of opioids PRN for patients with pain, patients die with unrelieved pain. Health care providers, hospitals in particular, need to focus more on pain in dying patients. An EoL conversation is one achievable intervention. J Pain Symptom Manage 2019;58:784e791. Ó

Willingness of patients with cancer pain to participate in end-of-life decisions: a multi-center cross-sectional study from three coastal provinces in southern China

“…On the other hand, unfortunate clinical experience will attack the patients’ confidence in disease recovery. Explosive pain cannot be generally relieved by using prescription of opioids and has been seen as an important cause that cancer patients may seek to hasten their deaths [ 41 ]. The patients are aware of ineffective treatment and worry about sudden deterioration of condition so that they have no opportunity to make EOLD.…”

Efficacy of Cingulotomy for Refractory Malignant Cancer Pain: A Case Series

“…Advanced cancer patients often suffer from diffuse pain secondary to metastatic disease that is inadequately treated with medications alone [1][2][3]. Intractable pain is a common complication of cancer, occurring in up to 75% of patients with advanced disease or about nine million patients annually.…”

Current management of cancer pain in Italy: Expert opinion paper

“…Despite improved pain assessment in clinical practice, patient awareness, and effective treatments, cancer-pain may be inadequately controlled approximately in up to one-third of the patients [ 5 , 6 ], especially in elderly patients [ 7 ]. Pain severity resulted in 38.0% prevalence of moderate to severe pain, from 31% after curative treatment to 45% in advanced cancer [ 1 , 8 ]; unfortunately, severe pain management is often inadequate, even for people facing the end-of-life transition with palliative and hospice care [ 9 , 10 ].…”
