GENERAL PRINCIPLES OF PALLIATIVE CARE
Early initiation of palliative care and survival (February 2017)
When initiated early in the disease course, palliative care improves clinical and quality of care outcomes; randomized trials in patients with cancer or advanced lung disease also report a survival advantage, although more diverse palliative care populations have not been studied. A meta-analysis of seven randomized trials involving 2184 patients concluded that there was no association between early initiation of palliative care and overall survival . Previous reports of a possible survival advantage may have reflected bias in patient selection; only one of the seven trials was rated as having a low risk of bias. (See "Benefits, services, and models of subspecialty palliative care", section on 'Rationale for palliative care'.)
Palliative care during hematopoietic cell transplantation (February 2017)
For patients with serious life-threatening illness, comprehensive palliative care can be successfully integrated with disease-modifying treatment. The benefits of delivering palliative care alongside potentially curative treatment were shown in a randomized trial of inpatient palliative care consultation versus usual transplant care in 160 adults with hematologic malignancies undergoing autologous or allogeneic hematopoietic cell transplantation . At two weeks posttransplant, the increase in depression, anxiety, and overall symptom burden was less in the intervention group, and the decrease in quality of life (QOL) was also smaller. Depression and QOL benefits persisted at three months. (See "Benefits, services, and models of subspecialty palliative care", section on 'Rationale for palliative care'.)
Opana ER withdrawn from the US market (July 2017)
A long-acting abuse-deterrent formulation of oxymorphone, Opana ER, is being voluntarily withdrawn from the United States (US) market at the request of the US Food and Drug Administration due to concerns related to injection abuse, including reports of thrombotic microangiopathy (TMA) when the oral formulation is injected intravenously (IV) [3-5]. The TMA is thought to be due to an inert component that was added to the formulation to make it crush-resistant and thus deter IV injection. Generic extended-release oxymorphone products remain on the US market. (See "Cancer pain management with opioids: Optimizing analgesia", section on 'Oxycodone, hydrocodone, hydromorphone, and oxymorphone' and "Drug-induced thrombotic microangiopathy", section on 'Drugs of abuse'.)
Safe storage of prescription opioids (May 2017)
Although safe storage of prescription opioid medications (eg, locked cabinet) is recommended, it infrequently occurs. In a United States nationally representative survey of over 1000 adults with prescription opioid use in the past 12 months, only 9 percent reported safe storage of their medications . In further analysis of those adults with children younger than 18 years of age in the household, safe storage was reported in less than one-third of households with young children and 12 percent of households with children older than six years of age . These results support the need for anticipatory guidance by health care providers, emphasizing opioid safe storage and how it may limit opioid misuse and overdose, especially in households with children and adolescents. Further research should focus on developing and implementing effective means of secure storage in households. (See "Opioid intoxication in children and adolescents", section on 'Safe storage'.)
Concurrent benzodiazepines in opioid-using patients and overdose risk (April 2017)
Benzodiazepines can potentiate the respiratory depressant effects of opioid medication, and concurrent use may be a factor in the rising rate of opioid overdose. In an analysis of a large sample of patients prescribed an opioid, the proportion who concurrently received a benzodiazepine nearly doubled over 12 years . Concurrent use of both medications was associated with an increased risk of opioid overdose compared with patients receiving only the opioid. Avoiding this medication combination may prevent some overdoses. (See "Prevention of lethal opioid overdose in the community", section on 'Risk factors'.)
Naldemedine for opioid-induced constipation (March 2017)
The benefit of naldemedine, an oral peripherally acting opioid receptor antagonist, for opioid-induced constipation (OIC) was shown in two identically designed 12-week phase III randomized trials conducted in patients with noncancer chronic pain and OIC . In a preliminary report, naldemedine, compared with placebo, decreased constipation and was well tolerated with no signs or symptoms of opioid withdrawal or decrease in opioid analgesic efficacy. Naldemedine has been approved in the United States for OIC in adult patients with chronic noncancer pain . However, efficacy has also been shown for treatment of OIC in cancer patients , and naldemedine can be used off label in this population. The European Medicines Agency has approved naldemedine for treatment of OIC without restriction to noncancer pain . (See "Cancer pain management with opioids: Prevention and management of side effects", section on 'Other oral agents'.)
Telotristat for refractory carcinoid syndrome diarrhea (March 2017)
Telotristat inhibits the production of serotonin by carcinoid tumors and reduces the frequency of carcinoid syndrome diarrhea. The randomized TELESTAR trial compared two doses of oral telotristat (250 mg and 500 mg, each taken three times daily) against placebo in 135 patients who had uncontrolled symptoms from carcinoid syndrome despite treatment with a somatostatin analog . Treatment with telotristat at either dose was associated with a reduction in bowel movement frequency compared with placebo, and the drug was well tolerated. Based upon these results, telotristat has been approved in the United States, in combination with somatostatin analog therapy, for the treatment of adults with diarrhea related to carcinoid syndrome that is inadequately controlled by somatostatin analog therapy alone . The recommended dose is 250 mg three times daily . (See "Treatment of the carcinoid syndrome", section on 'Telotristat'.)
SELECTED END-STAGE CONDITIONS
Decision aids for advance care planning in dementia (February 2017)
Structured interventions to improve advance care planning among families of patients with advanced dementia have not been well studied. In a cluster randomized trial, use of a video decision aid and structured family meeting resulted in better communication about end of life care, greater use of medical orders defining scope of treatment, and fewer hospital transfers compared with a control intervention (informational video and usual care plan meeting) . Audiovisual decision aids and structured meetings may thus be effective components of multidimensional decision-making support for families of patients with advanced dementia. (See "Palliative care of patients with advanced dementia", section on 'Advance care planning'.)
