ABSTRACT
Forty per cent of cancer pain associate neuropathic and nociceptive pain simultaneously, and refractory pain affects 15% of cancer pain. Methadone is an effective opioid in treating nociceptive pain and could have an effect on neuropathic pain. Uncertainty remains on its effects on the different subcomponents of neuropathic pain. OBJECTIVES: To identify which subcomponents of neuropathic cancer pain are addressed using methadone. METHODS: An observational prospective cohort study of palliative care inpatients after rotation for refractory neuropathic cancer pain. Pain intensity was assessed weekly for 28 days, using a Visual Analogue Scale (VAS) and the Neuropathic Pain Symptom Inventory (NPSI). RESULTS: Forty-eight patients were included and 17 completed the 28 days follow-up. VAS pain rating decreased by at least 20 mm in 47% of patients and the pain intensity was significantly lower at day 28 with 53% of patients with a VAS inferior to 4 (p<0.001). The pressure/squeezing component (NPSI score) decreased by more than 2 points in 50% of patients.A linear regression showed allodynia and pressure/squeezing were responsible for the largest part of the overall alleviation of pain (p=0.01). CONCLUSIONS: Methadone could significantly improve neuropathic pain through a targeted effect of allodynia and its pressure/squeezing component.

BACKGROUND: French demographic projection expects an increasing number of older, dependent patients in the next few years. A large proportion of this population lives in nursing homes and their transfer to hospitals at the end of life is an ongoing issue. OBJECTIVE: This study explored the factors influencing the transfer of patients living in nursing homes to hospital at the end of life. DESIGN: We used a mixed-methods questionnaire developed by an expert group and assessing different characteristics of the nursing homes. PARTICIPANTS: All the nursing homes in the Rhône-Alpes area (n=680) were surveyed. RESULTS: We obtained 466 (68%) answers. We found that a palliative care programme was present in 336 (72%) nursing homes. The majority had a coordinating physician 428 (82%) and a mean number of 6 nurses for 83 beds, with 83 (18%) having a night shift nurse. There was a mean number of 19 deaths per nursing home during the recorded year. The main cause of death was dementia (41%), cancer-related death (13%). Death occurred mostly in the nursing home (14 74%). Night shift nurse attendance was significantly associated with the place of death: 27 deaths occurred in nursing homes with a night shift nurse versus 12 in those without one (p<0001). CONCLUSIONS: The location of the death of frail elderly patients is a major health issue that needs to be addressed. Our results suggests that the presence of a night shift nurse decreases the number of emergency transfers and deaths in the hospital.
