Encouraging patients and families to influence change on a palliative care unit: value of patient satisfaction surveys.

This article describes how a series of patient satisfaction surveys on a palliative care unit were used to help influence the care provided to patients and their families. Innovative interventions aimed at addressing areas of lower satisfaction identified in the initial survey are described. The results from a follow-up survey provided the opportunity to evaluate whether our interventions were effective in improving patient satisfaction and highlight new areas of concern needing to be addressed.

Safe and Appropriate Use of Methadone in Hospice and Palliative Care: Expert Consensus White Paper.

Methadone has several unique characteristics that make it an attractive option for pain relief in serious illness, but the safety of methadone has been called into question after reports of a disproportionate increase in opioid-induced deaths in recent years. The American Pain Society, College on Problems of Drug Dependence, and the Heart Rhythm Society collaborated to issue guidelines on best practices to maximize methadone safety and efficacy, but guidelines for the end-of-life scenario have not yet been developed. A panel of 15 interprofessional hospice and palliative care experts from the U.S. and Canada convened in February 2015 to evaluate the American Pain Society methadone recommendations for applicability in the hospice and palliative care setting. The goal was to develop guidelines for safe and effective management of methadone therapy in hospice and palliative care. This article represents the consensus opinion of the hospice and palliative care experts for methadone use at end of life, including guidance on appropriate candidates for methadone, detail in dosing, titration, and monitoring of patients' response to methadone therapy.

Tetrodotoxin for moderate to severe cancer pain: a randomized, double blind, parallel design multicenter study.

Cancer pain is a serious public health issue and more effective treatments are needed. This study evaluates the analgesic activity of tetrodotoxin, a highly selective sodium channel blocker. This randomized, placebo-controlled, parallel design study of subcutaneous tetrodotoxin, in patients with moderate or severe unrelieved cancer pain persisting despite best available treatment, involved 22 centers across Canada. The design called for tetrodotoxin administered subcutaneously over Days 1-4 with a period of observation to Day 15 or longer. All patients could enroll into an open-label extension efficacy and safety trial. The primary endpoint was the proportion of analgesic responders in each treatment arm. Eighty-two patients were randomized, and results on 77 were available for analysis. There was a nonstatistically significant trend toward more responders in the active treatment arm based on the primary endpoint (pain intensity difference). However, analysis of secondary endpoints, and an exploratory post hoc analysis, suggested there may be a robust analgesic effect if a composite endpoint is used, including either fall in pain level, or fall in opioid dose, plus improvement in quality of life. Most patients described transient perioral tingling or other mild sensory phenomena within about an hour of each treatment. Nausea and other toxicities were generally mild, but one patient experienced a serious, adverse event, truncal and gait ataxia. This trial suggests tetrodotoxin may potentially relieve moderate to severe, treatment-resistant cancer pain in a large proportion of patients, and often for prolonged periods following treatment, but further study is warranted using a composite primary endpoint.

An open-label, multi-dose efficacy and safety study of intramuscular tetrodotoxin in patients with severe cancer-related pain.

Cancer pain is a prevalent and serious public health issue, and more effective treatments are needed. This study evaluates the analgesic activity of tetrodotoxin, a highly selective sodium channel blocker, in cancer pain. A Phase IIa, open-label, multicenter, dose-escalation study of intramuscular tetrodotoxin was conducted in patients with severe, unrelieved cancer pain. The study design called for six ascending dose levels of intramuscular tetrodotoxin, administered over a four-day treatment period in hospitalized patients, with six patients to be enrolled within each successive dose level. Twenty-four patients underwent 31 courses of treatment at doses ranging from 15 to 90 microg daily, administered in divided doses, over four days. Most patients described transient perioral tingling or other mild sensory phenomena within about an hour of each treatment. Nausea and other toxicities were generally mild, but two patients experienced a serious adverse event, truncal and gait ataxia, that resolved over days. Seventeen of 31 treatments resulted in clinically meaningful reductions in pain intensity, and relief of pain persisted for up to two weeks or longer. Two patients had opioids held due to narcosis concurrent with relief of pain. Somatic, visceral, or neuropathic pain could all respond, but it was not possible to predict which patients were more likely to have an analgesic effect. Tetrodotoxin was overall safe. It effectively relieved severe, treatment-resistant cancer pain in the majority of patients and often for prolonged periods after treatment. It may have a novel mechanism of analgesic effect. Further study is warranted.

Tetrodotoxin for Moderate to Severe Cancer-Related Pain: A Multicentre, Randomized, Double-Blind, Placebo-Controlled, Parallel-Design Trial.

OBJECTIVE: This study evaluated subcutaneous injections of tetrodotoxin (TTX) for the treatment of moderate to severe, inadequately controlled cancer-related pain. METHODS: Eligible patients were randomized to receive TTX (30 µg) or placebo subcutaneously twice daily for four consecutive days. Efficacy was assessed using pain and composite endpoints (including pain and quality of life measures), and safety was evaluated using standard measures. RESULTS: 165 patients were enrolled at 19 sites in Canada, Australia, and New Zealand, with 149 patients in the primary analysis "intent-to-treat" population. The primary analysis supports a clinical benefit of TTX over placebo based on the pain endpoint alone with a clinically significant estimated effect size of 16.2% (p = 0.0460). The p value was nominally statistically significant after prespecified (Bonferroni Holm) adjustment for the two primary endpoints but not at the prespecified two-sided 5% level. The mean duration of analgesic response was 56.7 days (TTX) and 9.9 days (placebo). Most common adverse events were nausea, dizziness, and oral numbness or tingling and were generally mild to moderate and transient. CONCLUSIONS: Although underpowered, this study demonstrates a clinically important analgesic signal. TTX may provide clinically meaningful analgesia for patients who have persistent moderate to severe cancer pain despite best analgesic care. This clinical study is registered with ClinicalTrials.gov (NCT00725114).

OA8†Caring for the family caregiver: working with volunteers to implement and improve a service to enable family caregivers to maintain their own wellbeing.

BACKGROUND: Family caregivers suffer physically, mentally, and spiritually. Community volunteers play an important role in supporting patients at the end of life or former caregivers in bereavement. However, there are no research reports of volunteer services focused on maintaining the wellbeing of end-of-life caregivers. AIM: To have volunteers, a hired volunteer coordinator, health care providers, and researchers implement and formatively evaluate a volunteer service to enable family caregivers to maintain their well being while providing care and subsequent bereavement. This presentation will focus on the volunteers' roles with the project as both agents of change to the service and as support for the caregivers. METHOD: A qualitative formative evaluation informed by Guba and Lincoln's Fourth Generation Evaluation (1989) participatory design was conducted. Data was collected through individual interviews, focus groups, participant observation during volunteer support meetings, and through volunteers' written reflections. RESULTS: Amongst the volunteers, volunteer coordinator, and principal investigator, there was mutual respect for and interest in learning about everyone's roles and experiences in the project. The experience was rewarding because they felt they helped the family caregiver and enjoyed developing and improving the service and working in a supportive team. Volunteers' challenges included being nervous for their first meeting with a caregiver, and frustration with some rules put in place to protect them (e.g. not helping the caregiver with direct care for the patient). CONCLUSION: Volunteers can be an effective part of the research team, while providing valuable support and encouragement for family caregivers to maintain their own wellbeing.
