Prescription Opioids Dispensed to Patients with Cancer with Bone Metastasis: 2011-2017

American Society for Pain Management Nursing and Hospice and Palliative Nurses Association Position Statement: Pain Management at the End of Life

Fundamental to the quality of life is assisting patients in relieving pain including at the end of life. Compassionate, effective, evidence-based pain care for the dying improves the quality of life for patients and may reduce distress and complicated bereavement in the loved ones witnessing this death. However, efforts designed to mitigate the consequences of the opioid epidemic have seriously compromised pain care at the end of life. This has created an urgent need to focus on the barriers to relief, and solutions necessary to provide safe and effective pain and symptom management in this population. To that end, a committee of experts was convened by the American Society for Pain Management Nursing and the Hospice and Palliative Nursing Association. These experts reviewed the current literature, developed a draft position statement which underwent consecutive revisions. This statement was then endorsed by the respective organizations. Elucidation of barriers to effective pain control in advanced disease allows targeted interventions; including those related to clinical care, education, accessibility, and research. As nurses, we must continuously advocate for humane and dignified care, promoting ethical, effective pain and symptom management at the end of life for all.

Scheduled and Breakthrough Opioid Use for Cancer Pain in an Inpatient Setting at a Tertiary Cancer Hospital

Background: Our aim was to examine the frequency and prescription pattern of breakthrough (BTO) and scheduled (SCH) opioids and their ratio (BTO/SCH ratio) of use, prior to and after referral to an inpatient supportive care consult (SCC) for cancer pain management (CPM). Methods and Materials: Patients admitted at the MD Anderson Cancer Center and referred to a SCC were retrospectively reviewed. Cancer patients receiving SCH and BTO opioids for ≥24 h were eligible for inclusion. Patient demographics and clinical characteristics, including the type and route of SCH and BTO opioids, daily opioid doses (MEDDs) of SCH and BTO, and BTO/SCH ratios were reviewed in patients seen prior to a SCC (pre-SCC) and during a SCC. A normal BTO ratio was defined as 0.5-0.2. Results: A total of 665/728 (91%) patients were evaluable. Median pain scores (p < 0.001), BTO MEDDs (p < 0.001), scheduled opioid MEDDs (p < 0.0001), and total MEDDs (p < 0.0001) were higher, but the median number of BTO doses was fewer (2 vs. 4, p < 0.001), among patients seen at SCC compared to pre-SCC. A BTO/SCH ratio over the recommended ratio (>0.2) was seen in 37.5% of patients. The BTO/SCH ratios in the pre-SCC and SCC groups were 0.10 (0.04, 0.21) and 0.17 (0.10, 0.30), respectively, p < 0.001. Hydromorphone and Morphine were the most common BTO and SCH opioids prescribed, respectively. Patients in the early supportive care group had higher pain scores and MEDDs. Conclusions: BTO/SCH ratios are frequently prescribed higher than the recommended dose. Daily pain scores, BTO MEDDs, scheduled opioid MEDDs, and total MEDDs were higher among the SCC group than the pre-SCC group, but the number of BTO doses/day was lower.

Trends in new and persistent opioid use in older adults with and without cancer

BACKGROUND

The impact of ongoing efforts to decrease opioid use on patients with cancer remains undefined. Our objective was to determine trends in new and additional opioid use in patients with and without cancer.

METHODS

This retrospective cohort study used data from Surveillance, Epidemiology, and End Results program-Medicare for opioid-naive patients with solid tumor malignancies diagnosed from 2012 through 2017 and a random sample of patients without cancer. We identified 238 470 eligible patients with cancer and further focused on 4 clinical strata: patients without cancer, patients with metastatic cancer, patients with nonmetastatic cancer treated with surgery alone ("surgery alone"), and patients with nonmetastatic cancer treated with surgery plus chemotherapy or radiation therapy ("surgery+"). We identified new, early additional, and long-term additional opioid use and calculated the change in predicted probability of these outcomes from 2012 to 2017.

RESULTS

New opioid use was higher in patients with cancer (46.4%) than in those without (6.9%) (P < .001). From 2012 to 2017, the predicted probability of new opioid use was more stable in the cancer strata (relative declines: 0.1% surgery alone; 2.4% surgery+; 8.8% metastatic cancer), than in the noncancer stratum (20.0%) (P < .001 for each cancer to noncancer comparison). Early additional use declined among surgery patients (‒14.9% and ‒17.5% for surgery alone and surgery+, respectively) but was stable among patients with metastatic disease (‒2.8%, P = .50).

CONCLUSIONS

Opioid prescribing declined over time at a slower rate in patients with cancer than in patients without cancer. Our study suggests important but tempered effects of the changing opioid climate on patients with cancer.

Healthcare provider perceptions and reported practices regarding opioid prescription for patients with chronic cancer pain

PURPOSE

Data indicates that clinicians might be under-prescribing opioids for patients with chronic cancer pain, and this could impact adequate pain management. Few studies have sought to understand healthcare provider (HCP) perceptions and practices regarding the prescription of opioids for chronic cancer pain. We assessed HCP perceptions and practices regarding opioid prescription for patients with chronic cancer pain since the onset of the COVID-19 pandemic.

METHODS

An anonymous cross-sectional survey was conducted among 186 HCPs who attended an opioid educational event in April 2021 and 2022.

RESULTS

Sixty-one out of 143 (44%) opioid prescribers reported reluctance to prescribe opioids for chronic cancer pain. In a multivariate logistic model, younger participants (log OR - 0.04, 95% CI - 0.085, - 0.004; p = 0.033) and pain medicine clinicians (log OR - 1.89, CI - 3.931, - 0.286; p = 0.034) were less reluctant, whereas providers who worry about non-medical opioid use were more reluctant to prescribe opioids (log OR 1.58 95% CI 0.77-2.43; p < 0.001). Fifty-three out of 143 (37%) prescribers had experienced increased challenges regarding opioid dispensing at pharmacies, and 84/179 (47%) of all respondents reported similar experience by their patients. Fifty-four out of 178(30%) were aware of opioid-related harmful incidents to patients or their families, including incidents attributed to opioid misuse by a household or family member.

CONCLUSION

A considerable number of opioid prescribers were reluctant to prescribe opioids for patients with chronic cancer pain. Many reported challenges regarding dispensing of opioids at the pharmacies. These may be unintended consequences of policies to address the opioid crisis. Future measures should focus on addressing regulatory barriers without undermining the gains already made to combat the opioid crisis.

Trajectories and predictors of high-occurrence pain flares in ambulatory cancer patients on opioids

BACKGROUND

Pain flares have a substantive impact on the quality of life and well-being of patients with cancer. We identified longitudinal trajectories (clusters) of cancer pain flares in ambulatory patients and sociodemographic and clinical predictors of these trajectories.

METHODS

In a prospective cohort study using ecological momentary assessment (mEMA), we collected patient-reported daily pain flare ratings data over 5 months and identified predictors and correlates using validated measures.

RESULTS

The mean age of the sample (N = 270) was 60.9 years (SD = 11.2), 64.8% were female, and 32.6% self-identified as African American. Four pain flare clusters were identified. The "high-occurrence" cluster (23% of patients) experienced 5.5 (SD = 5.47) daily flares, whereas low-moderate clusters (77%) reported 2.4 (SD = 2.74) daily flares (P < .000). Those in the high-occurrence cluster reported higher pain scores (P = .000), increased pain-related interference (P = .000), depressive symptoms (P = .023), lower quality of life (P = .001), and reduced pain self-efficacy (P = .006). Notably, 67.2% of those prescribed opioids as needed (PRN only) were in the high-occurrence pain flare cluster, compared with 27.9% with PRN and around-the-clock opioid prescriptions (P = .024). Individual predictors of high-occurrence pain flares were income below $30 000, unemployment, being African American, lower education level, Medicaid insurance, current opioid misuse (COMM), baseline inpatient hospital stay duration, and PRN-only opioid regimen. In the multiple predictor model, lower education level, unemployment, COMM score, extended inpatient duration, and PRN-only opioid regimen remained significant.

CONCLUSION

In ambulatory patients with cancer, high occurrence of pain flares may be mitigated by attention to opioid prescription factors and addressing social determinants of health needs of underserved patients.

Effectiveness of Long-Term Opioid Therapy for Chronic Pain in an Outpatient Palliative Medicine Clinic

Background: Despite widespread use of opioid therapy in outpatient palliative medicine, there is limited evidence supporting its efficacy and safety in the long term. Objectives: We sought to improve overdose risk scores, maintain pain reduction, and preserve patient function in a cohort with severe chronic pain as we managed opioid therapy for a duration of four years in an outpatient palliative care clinic. Design: Over four years, we provided ongoing goal-concordant outpatient palliative care, including opioid therapy, using quarterly clinical encounters for a patient cohort with chronic pain. Setting/Subjects: The project took place in the outpatient palliative medicine clinic of a regional cancer center in Orlando, Florida (United States). The subjects were a cohort group who received palliative care during the time period between July 2018 and October 2022. Measurements: Key metrics included treatment-related reduction in pain intensity, performance scores, and overall overdose risk scores. Secondary metrics included cohort demographics, average daily opioid use in morphine milligram equivalents and categorization of type of pain. Results: In 97 patients, we observed a stable mean treatment-related reduction in pain intensity of 4.9 out of 10 points over four years. The cohort showed a 2-point (out of 100) improvement in performance scores and an 81-point (out of 999) reduction in mean overall overdose risk score. Conclusions: We present evidence that providing outpatient palliative care longitudinally over four years offered lasting treatment-related reductions in pain intensity, preservation of performance status, and reduction in overall overdose risk.

Improvement in patient-reported pain among patients with metastatic cancer and its association with opioid prescribing

PURPOSE

Opioids are a mainstay of cancer pain management; however, patients with metastatic cancer are often excluded from studies, leading to a lack of evidence on whether increased prescribing (dosage and/or duration) results in improved outcomes for this population. This study aimed to investigate whether increased opioid prescribing is associated with an improvement in patient-reported pain among patients with metastatic cancer.

PATIENTS AND METHODS

A retrospective cohort of all adult patients diagnosed with stage IV cancers, who completed at least two patient-reported outcomes (PROs) within 30 days of each other, was identified from administrative data. Opioid prescriptions were categorized by dosage level and number of prescription days. Multivariable logistic regression was used to investigate the association between opioid prescribing and clinically important improvement in pain score (≥ 1 point change on the Edmonton Symptom Assessment System).

RESULTS

A total of 2169 patients were included, 770 (35.5%) of whom had active opioid prescription between PROs, with an average daily dosage of 86.1 mg of oral morphine equivalent. Active prescription was associated with improvement in pain (OR = 2.17, P < 0.001). However, among patients with active prescription, neither dosage nor number of prescription days was significantly associated with pain improvement.

CONCLUSION

Opioid prescription is important for treating cancer-related pain; however, increased dosage or duration may not be leading to greater improvements in pain. Patients with metastatic cancer who are receiving increased opioid prescribing may have difficult-to-treat pain and may benefit from multidisciplinary pain management strategies to supplement opioid prescription and improve outcomes.

The Stigma Surrounding Opioid Use as a Barrier to Cancer-Pain Management: An Overview of Experiences with Fear, Shame, and Poorly Controlled Pain in the Context of Advanced Cancer

Cancer-related pain affects a majority of patients with advanced cancer and is often undertreated. The treatment of this pain is largely reliant on the use of opioids, which are essential medicines for symptom management and the maintenance of quality of life (QoL) for patients with advanced cancer. While there are cancer-specific guidelines for the treatment of pain, widespread publication and policy changes in response to the opioid epidemic have drastically impacted perceptions of opioid use. This overview therefore aims to investigate how manifestations of opioid stigma impact pain management in cancer settings, with an emphasis on the experiences of patients with advanced cancer. Opioid use has been widely stigmatized in multiple domains, including public, healthcare, and patient populations. Physician hesitancy in prescribing and pharmacist vigilance in dispensing were identified as barriers to optimal pain management, and may contribute to stigma in the context of advanced cancer. Evidence in the literature suggests that opioid stigma may result in patient deviations from prescription instructions, which generally leads to pain undertreatment. Patients reflected on experiencing shame and fear surrounding their prescription opioid use and feeling uncomfortable communicating with their healthcare providers on these topics. Our findings indicate that future work is required to educate patients and providers in order to de-stigmatize opioid use. Through alleviating stigma, patients may be better able to make decisions regarding their pain management which lead to freedom from cancer-related pain and improved QoL.

Endogenous opiates and behavior: 2021

This paper is the forty-fourth consecutive installment of the annual anthological review of research concerning the endogenous opioid system, summarizing articles published during 2021 that studied the behavioral effects of molecular, pharmacological and genetic manipulation of opioid peptides and receptors as well as effects of opioid/opiate agonizts and antagonists. The review is subdivided into the following specific topics: molecular-biochemical effects and neurochemical localization studies of endogenous opioids and their receptors (1), the roles of these opioid peptides and receptors in pain and analgesia in animals (2) and humans (3), opioid-sensitive and opioid-insensitive effects of nonopioid analgesics (4), opioid peptide and receptor involvement in tolerance and dependence (5), stress and social status (6), learning and memory (7), eating and drinking (8), drug abuse and alcohol (9), sexual activity and hormones, pregnancy, development and endocrinology (10), mental illness and mood (11), seizures and neurologic disorders (12), electrical-related activity and neurophysiology (13), general activity and locomotion (14), gastrointestinal, renal and hepatic functions (15), cardiovascular responses (16), respiration and thermoregulation (17), and immunological responses (18).

Health Care Provider Attitudes and Beliefs Toward Nonmedical Opioid Use in Patients with Cancer Pain

Background: Data on health care providers' (HCPs') perceptions about patients with cancer pain and nonmedical opioid use (NMOU) are lacking. We examined the perceptions and attitudes of HCPs and assessed the usefulness of an interdisciplinary opioid stewardship program (OSP) while caring for these patients. Methods: An anonymous cross-sectional survey was conducted among the supportive care HCPs between September and November 2021. Results: Of 85 HCPs, 64 responded (75%) to the survey. Participants perceived that NMOU is underdiagnosed (42/64; 67%), and caring for such patients is difficult (58/64, 91%) and time consuming (54/64, 87%). A majority (50/51, 98%) were aware of the OSP, and (48/51; 94%) found it helpful. Conclusion: HCPs reported that NMOU is underdiagnosed and is challenging to manage. They endorsed the utility of an OSP in managing patients with concurrent cancer pain and NMOU. Future research should identify ways to standardize care and integrate OSP in routine supportive oncology practice.

Use of Opioids for Adults With Pain From Cancer or Cancer Treatment: ASCO Guideline

PURPOSE

To provide guidance on the use of opioids to manage pain from cancer or cancer treatment in adults.

METHODS

A systematic review of the literature identified systematic reviews and randomized controlled trials of the efficacy and safety of opioid analgesics in people with cancer, approaches to opioid initiation and titration, and the prevention and management of opioid adverse events. PubMed and the Cochrane Library were searched from January 1, 2010, to February 17, 2022. American Society of Clinical Oncology convened an Expert Panel to review the evidence and formulate recommendations.

RESULTS

The evidence base consisted of 31 systematic reviews and 16 randomized controlled trials. Opioids have primarily been evaluated in patients with moderate-to-severe cancer pain, and they effectively reduce pain in this population, with well-characterized adverse effects. Evidence was limited for several of the questions of interest, and the Expert Panel relied on consensus for these recommendations or noted that no recommendation could be made at this time.

RECOMMENDATIONS

Opioids should be offered to patients with moderate-to-severe pain related to cancer or active cancer treatment unless contraindicated. Opioids should be initiated PRN (as needed) at the lowest possible dose to achieve acceptable analgesia and patient goals, with early assessment and frequent titration. For patients with a substance use disorder, clinicians should collaborate with a palliative care, pain, and/or substance use disorder specialist to determine the optimal approach to pain management. Opioid adverse effects should be monitored, and strategies are provided for prevention and management.Additional information is available at www.asco.org/supportive-care-guidelines.

Medical Marijuana Legalization and Opioid- and Pain-Related Outcomes Among Patients Newly Diagnosed With Cancer Receiving Anticancer Treatment

Importance

The past decade saw rapid declines in opioids dispensed to patients with active cancer, with a concurrent increase in marijuana use among cancer survivors possibly associated with state medical marijuana legalization.

Objective

To assess the associations between medical marijuana legalization and opioid-related and pain-related outcomes for adult patients receiving cancer treatment.

Design, Setting, and Participants

This cross-sectional study used 2012 to 2017 national commercial claims data and a difference-in-differences design to estimate the associations of interest for patients residing in 34 states without medical marijuana legalization by January 1, 2012. Secondary analysis differentiated between medical marijuana legalization with and without legal allowances for retail dispensaries. Data analysis was conducted between December 2021 and August 2022. Study samples included privately insured patients aged 18 to 64 years who received anticancer treatment during the 6 months after a new breast (in women), colorectal, or lung cancer diagnosis.

Exposures

State medical marijuana legalization that took effect between 2012 and 2017.

Main Outcomes and Measures

Having 1 or more days of opioids, 1 or more days of long-acting opioids, total morphine milligram equivalents of any opioid dispensed to patients with 1 or more opioid days, and 1 or more pain-related emergency department visits or hospitalizations (hereafter, hospital events) during the 6 months after a new cancer diagnosis. Interaction terms were included between each policy indicator and an indicator of recent opioids, defined as having 1 or more opioid prescriptions during the 12 months before the new cancer diagnosis. Logistic models were estimated for dichotomous outcomes, and generalized linear models were estimated for morphine milligram equivalents.

Results

The analysis included 38 189 patients newly diagnosed with breast cancer (38 189 women [100%]), 12 816 with colorectal cancer (7100 men [55.4%]), and 7190 with lung cancer (3674 women [51.1%]). Medical marijuana legalization was associated with a reduction in the rate of 1 or more opioid days from 90.1% to 84.4% (difference, 5.6 [95% CI, 2.2-9.0] percentage points; P = .001) among patients with breast cancer with recent opioids, from 89.4% to 84.4% (difference, 4.9 [95% CI, 0.5-9.4] percentage points; P = .03) among patients with colorectal cancer with recent opioids, and from 33.8% to 27.2% (difference, 6.5 [95% CI, 1.2-11.9] percentage points; P = .02) among patients with lung cancer without recent opioids. Medical marijuana legalization was associated with a reduction in the rate of 1 or more pain-related hospital events from 19.3% to 13.0% (difference, 6.3 [95% CI, 0.7-12.0] percentage points; P = .03) among patients with lung cancer with recent opioids.

Conclusions and Relevance

Findings of this cross-sectional study suggest that medical marijuana legalization implemented from 2012 to 2017 was associated with a lower rate of opioid dispensing and pain-related hospital events among some adults receiving treatment for newly diagnosed cancer. The nature of these associations and their implications for patient safety and quality of life need to be further investigated.

Interdisciplinary intervention for the management of nonmedical opioid use among patients with cancer pain

BACKGROUND

Few studies have assessed interventions aimed at managing nonmedical opioid use (NMOU) behavior among patients with cancer. The authors developed the Compassionate High-Alert Team (CHAT) intervention to manage patients receiving opioids for cancer pain who demonstrate NMOU behavior. The objective of this study was to determine the change in frequency of NMOU behaviors, pain intensity, and opioid requirements among those who received the intervention.

METHODS

A total of 130 patients receiving opioids for cancer pain that had documented evidence of NMOU and received the CHAT intervention were reviewed. Demographic and clinical information such as NMOU behaviors, pain scores, and morphine equivalent daily dose at baseline, 3, and 6 months post-intervention was obtained.

RESULTS

NMOU behaviors significantly decreased from a median (interquartile range) of 2 (1-3) at baseline to 0 (0-1) at both 3 and 6 months post-intervention (p < .001). A total of 45 of 75 (60%) and 31 of 50 (62%) of CHAT recipients achieved complete response to the intervention at 3 and 6 months, respectively. Higher baseline number of NMOU behaviors was independently associated with patient response to the intervention (odds ratio [OR], 1.97; 95% confidence interval [CI],1.09-4.28, p = .049 at 3 months; OR, 2.5; 95% CI, 1.20-6.47, p = .03 at 6 months). The median pain score decreased from 7 at baseline to 6 at both 3 and 6 months (p = .01). Morphine equivalent daily dose did not significantly change during that same period (143 mg/day vs. 139 mg/day, p = .13).

CONCLUSIONS

Most patients who received the CHAT intervention improved in their NMOU behaviors and pain intensity scores 3 and 6 months post-intervention. These preliminary findings support the efficacy of CHAT in managing patients receiving opioids for cancer pain who demonstrate NMOU behavior.

Cancer pain during an epidemic and a pandemic

PURPOSE OF REVIEW

As our global population ages, cancer has become more prevalent. Thankfully, oncologic treatments are highly effective, leading to significantly improved rates of long-term survival. However, many of these therapies are associated with persistent pain syndromes. Clinicians caring for people with cancer must understand how the influence of the current epidemic of opioid misuse and the coronavirus disease 2019 (COVID-19) pandemic have complicated cancer pain management. Creative solutions can emerge from this knowledge.

RECENT FINDINGS

Persistent pain due to cancer and its treatment can be managed through multimodal care, although efforts to mitigate the opioid misuse epidemic have created challenges in access to appropriate treatment. Isolation measures associated with the COVID-19 pandemic have limited access to nonpharmacologic therapies, such as physical therapy, and have exacerbated mental health disorders, including anxiety and depression.

SUMMARY

Cancer pain treatment requires more nuanced assessment and treatment decisions as patients live longer. Societal factors multiply existing challenges to cancer pain relief. Research is needed to support safe and effective therapies.
