RESUMO
Although weak evidence exists to support subanesthetic ketamine for cancer pain treatment, successful use may be hindered in the absence of standardized dosing guidance. We aimed to compare the success rates of intravenous ketamine fixed-rate versus weight-based dosing strategies for cancer pain treatment, and to assess patient characteristics that correlate with treatment success. We conducted a single-center retrospective review including non-critically ill adults with cancer pain who received subanesthetic ketamine for at least 24-h. All patients received fixed-rate ketamine; weight-based doses were retrospectively determined using total body weight. Treatment was considered successful if after reaching the maximum prescribed ketamine dose the patient had a 30% reduction in: baseline pain score, as-needed opioid use, or total morphine equivalent daily dose over a standardized 24-h. Of 105 included patients, 51 (48.6%) successfully responded to ketamine. Responders had lower fixed-rate ketamine doses compared to non-responders (median[IQR] 15 mg/hr[10-15] vs. 15 mg/hr[15-20], p = 0.043), but no difference in retrospectively calculated weight-based doses (0.201 ± 0.09 mg/kg/hr vs. 0.209 ± 0.08 mg/kg/hr, p = 0.59). Responders had higher daily opioid requirements at baseline compared to non-responders (p = 0.04). Though underpowered, our findings suggest that weight-based ketamine dosing may not convey additional benefit over fixed-rate dosing.
RESUMO
INTRODUCTION: Medicare decedents with cancer often receive intensive care during the last month of life; however, little information exists on longer end-of-life care trajectories. MATERIALS AND METHODS: Using SEER-Medicare data, we selected older adults diagnosed with lung cancer between 2008 and 2013 who survived at least six months and died between 2008 and 2014. Each month we assessed claims to assign care categories ordered by intensity as follows: full-month inpatient/skilled nursing facility > cancer-directed therapy (CDT) only > concurrent CDT and symptom management and supportive care services (SMSCS) > SMSCS only > full-month hospice. We assigned each decedent to one of six trajectories: stable hospice, stable SMSCS, stable CDT with or without concurrent SMSCS, decreasing intensity, increasing intensity, and mixed. Multinomial logistic regression estimated associations between socio-demographics, calendar year, and area hospice use rates with end-of-life trajectory. RESULTS: The sample (N = 24,342) was predominantly aged ≥75 years (59.4%) and non-Hispanic White (80.5%); 19.1% lived in healthcare referral regions where ≤50% of cancer decedents received hospice care. Overall, 6.5% were continuously hospice enrolled, 25.6% received SMSCS only, and 29.4% experienced decreasing intensity; 3.9% received CDT or concurrent care, while 8.7% experienced an increase in intensity. Higher healthcare referral region hospice rates were associated with decreasing end-of-life intensity; Black, non-Hispanic decedents had a higher risk of increasing intensity and mixed patterns. DISCUSSION: Among older decedents with lung cancer, 62% had six-month end-of-life trajectories indicating low or decreasing intensity, but few received persistent CDT. Demographic characteristics, including race/ethnicity, and contextual measures, including area hospice use patterns, were associated with end-of-life trajectory.

Use of topical morphine gel was explored retrospectively for treatment of painful chronic wounds in hospitalized adults. Systemic opioid use and pain intensity were characterized before and after morphine gel initiation using morphine equivalent daily dose (MEDD) and the Defense and Veterans Pain Rating Scale (DVPRS) score at 24 hours before compared to 24 hours, 48 hours, and one week after morphine gel initiation. Twenty-three patients received 371 applications of topical morphine gel. The median number of applications received was 8.0 [5.0 to 26.0] per patient. Median change in MEDD 24 hours after morphine gel initiation was 0.0 mg [-15.3 to 11.3] (n = 21), 48 hours after was -4.4 mg [-27.5 to 8.8] (n = 20), and one week after was -7.5 mg [-41.9 to -0.3] (n = 12). Median change in DVPRS score 24 hours after morphine gel initiation was 0.0 [-0.5 to 1.5] (n = 13), 48 hours after was -0.5 [-3.25 to 0.0] (n = 14), and one week after was 1.0 [-1.0 to 3.5] (n = 9). In this single-center analysis, patients with painful chronic wounds treated with morphine gel required lower doses of systemic opioids. Topical morphine gel may provide analgesia while sparing systemic opioid use.

Background: End-stage respiratory disease and compromised clinical status can hinder patients' ability to use inhalers for effective symptom management. Nebulized and oral medications offer an alternative drug delivery method that may provide therapeutic benefits and reduce medication expenditure. Objectives: Primary research objectives were to determine the cost per patient per claim per day for inhaler devices, nebulized medications, or oral corticosteroids and to estimate the monetary waste generated by using inhalers at the end of life. Design: A retrospective pharmacoeconomic analysis of claims adjudicated by a national hospice-centric pharmacy benefit manager between January 1, 2017, and December 31, 2019. Setting/Subjects: A total of 37,935 adult patients (aged ≥18 years) admitted to hospice with a primary diagnosis of end-stage respiratory disease in the United States were included in the study. Results: A total of 295,451 claims for inhalers, nebulized medications, and oral corticosteroids were analyzed. The mean costs per patient per claim per day were $10.64 for inhalers, $3.28 for nebulized medications, and $1.02 for oral corticosteroids. These costs were significantly different from each other (all p values <0.001). Total monetary waste resulting from unused inhaler doses was $1,040,669, with 21.0%, 13.1%, and 7.3% of patients having claims for inhalers within 30, 14, and 7 days of discharge, respectively. Conclusions: Inhaler use near the end of life generates a significant amount of monetary waste. Using a combination of nebulized and oral medications could reduce health care costs. Nebulized medications may generate less waste since providers can tailor the dispensed supply to the patient's needs rather than using the standard one-month supply of inhaler devices.

Introduction: Palliative care is beneficial for patients with advanced lung cancer, but the optimal model of palliative care delivery is unknown. We investigated healthcare utilization before and after embedding a palliative care physician within a thoracic medical oncology "onco-pall" clinic. Methods: This is a retrospective cross-sectional cohort study comparing healthcare outcomes in two cohorts: "pre-cohort" 12 months prior to and "post-cohort" 12-months after the onco-pall clinic start date. Patients were included if they had a new diagnosis of lung cancer and received care at The Ohio State University Thoracic Oncology Center, and resided in Franklin County or 6 adjacent counties. During the pre-cohort time period, access to palliative care was available at a stand-alone palliative care clinic. Palliative care intervention in both cohorts included symptom assessment and management, advance care planning, and goals of care discussion as appropriate. Outcomes evaluated included rates of emergency department (ED) visits, hospital admissions, 30-day readmissions, and intensive care unit (ICU) admissions. Estimates were calculated in rates per-person-years and with Poisson regression models. Results: In total, 474 patients met criteria for analysis (214 patients included in the pre-cohort and 260 patients in the post-cohort). Among all patients, 52% were male and 48% were female with a median age of 65 years (range 31-92). Most patients had non-small cell lung cancer (NSCLC - 17% stage 1-2, 20% stage 3, 47% stage 4) and 16% had small cell lung cancer. The post-cohort was older [median age 66 years vs 63 years in the pre-cohort (p-value: < 0.01)]. The post-cohort had a 26% reduction in ED visits compared to the pre-cohort, controlling for age, race, marital status, sex, county, Charlson score at baseline, cancer type and stage (adjusted relative risk: aRR: 0.74, 95% CI: 0.58-0.94, p-value = 0.01). Although not statistically significant, there was a 29% decrease in ICU admissions (aRR: 0.71, 95% CI: 0.41-1.21, p-value = 0.21) and a 15% decrease in hospital admissions (aRR: 0.85, 95% CI: 0.70-1.03, p-value = 0.10). There was no difference in 30-day readmissions (aRR: 1.03, 95% CI: 0.73-1.45, p-value = 0.85). Conclusions: Embedding palliative care clinics within medical oncology clinics may decrease healthcare utilization for patients with thoracic malignancies. Further evaluation of this model is warranted.
RESUMO
Oncology and Palliative Medicine lack guidance on routine opioid risk screening and compliance monitoring. This study explored relationships among risk screening and aberrant medication related behaviors in patients with advanced lung cancer receiving embedded palliative care. This was a single center, prospective study and data was collected from December 2018 to March 2020. At the initial palliative visit, patients provided a baseline urine drug screen (UDS) test and completed the Screener and Opioid Assessment for Patients with Pain - Revised (SOAPP-R) self-assessment. Clinical pharmacists provided comprehensive review and interpretation of UDS results. Among 39 patients, 12 (30.8%) scored positive for risk of aberrant medication behaviors on the SOAPP-R. Only 34 of 39 patients provided a baseline UDS test and were included in further analysis. Prior to pharmacist review, 11/11 (100%) baseline UDS results in the positive-risk group and 13/23 (56.5%) in the negative-risk group appeared unexpected (p = 0.01). After pharmacist review, aberrant baseline UDS results were confirmed for 5/11 (45.5%) positive-risk and 4/23 (17.4%) negative-risk patients (p = 0.11). Overall, the SOAPP-R alone may be inadequate in this population and clinical pharmacists play an important role in comprehensive UDS result interpretation. Future studies are needed to validate this risk-screening tool in palliative cancer populations.

BACKGROUND: Rather than early hospice enrollment, most Medicare beneficiaries receive "usual care" in the last months of life, outside of the hospice setting. While care intensity during the last weeks of life has been studied extensively, patterns of symptom management services (SMS) and/or cancer-directed therapies (CDT) received over a 6-month end-of-life period have not. METHODS: This retrospective study used the Surveillance, Epidemiology, and End Results (SEER)-Medicare database to identify decedents diagnosed with lung cancer at age ≥ 66 years between January 2007 and December 2013 who survived ≥ 6 months from diagnosis. Medicare claims identified receipt of SMS and/or CDT. We created monthly indicators for care content (SMS-only, CDT-only, or both; otherwise full-month hospice or inpatient/skilled nursing). Multinomial logistic regression estimated associations between sociodemographics and comorbidity, with care content in the final month. RESULTS: Between 6 and 1 months before death, full-month hospice and inpatient/skilled nursing increased; CDT decreased from 31.9 to 18.5%; SMS increased from 86.6 to 97.7%. Relative to full-month hospice, the percentage of patients receiving SMS-only was higher for males, unmarried, younger age, and higher comorbidity; the percentage receiving CDT was also higher for males, unmarried, and younger age, but decreased with increasing comorbidity and over calendar time. CONCLUSION: Among lung cancer decedents observed in the outpatient, nonhospice setting, SMS receipt increased and was nearly universal as death approached. CDT diminished dramatically over the end-of-life period. Associations between sociodemographic characteristics and care setting suggest differences in care preferences or access barriers. Claims represent an important resource for characterizing end-of-life care patterns.

CONTEXT: Dysphagia is a common concern, especially in the last several days of life. Medications are often crushed for ease of administration for individuals with swallowing difficulty. OBJECTIVES: To assess palatability of commonly used crushed over-the-counter (OTC) medications. A secondary objective is to evaluate pharmacist knowledge and opinions of crushing medications. METHODS: Pharmacist participants sampled crushed OTC medications and completed presampling and postsampling surveys about crushing medications. Participants were excluded for current smoking or tobacco use, pregnancy, allergy to any study medication or applesauce, or potential drug-drug interaction with study medications. Eight OTC medications were crushed and mixed in applesauce: naproxen, fexofenadine, phenazopyridine, multivitamin, loperamide, famotidine, sennosides, and sennosides-docusate. Participants were blinded to medication samples and control (plain applesauce). Samples were rated from one (least palatable) to five (most palatable). Investigators recorded participants' comments, behaviors, and facial expressions during sampling. RESULTS: Nineteen volunteers completed the study. Most participants rated three samples as not palatable (score of two or less): fexofenadine, 16 (84%); loperamide, 13 (68%); and sennosides-docusate, 16 (84%). All participants rated famotidine and sennosides palatable. The percentage of participants who would consider palatability in recommendations for crushing medications increased from 47% prestudy to 79% poststudy. CONCLUSION: Palatability should be considered when recommending crushed medications. Survey responses indicate that pharmacists' opinions of crushed medications changed after this palatability experiment. Clinicians should evaluate the appropriateness of all medications when dysphagia is a concern and deprescribe medications when appropriate to reduce burden for patients and caregivers.

BACKGROUND: Certain cancer types and subsequent treatment can cause or worsen pain and emotional distress, leading to functional limitation, particularly among a growing population of older adults with cancer. METHODS: We constructed a national sample of older adult Medicare beneficiaries with cancer using the 2007-2012 Surveillance, Epidemiology and End Results (SEER)-Medicare Health Outcomes Survey (MHOS) database linked to Medicare Part D enrollment and prescription claims data. MHOS survey responses described functional limitations due to pain and emotional distress. Using multivariable logistic regression, we estimated the association between participant characteristics and patient-reported functional limitation due to pain and emotional distress and subsequent prescription medication use. RESULTS: Among 9105 older adults with cancer, aged 66-102 years (y), 68.6% reported moderate to severe functional limitation due to pain, and 48.3% reported moderate to severe functional limitation due to emotional distress. Nearly 10% reported severe functional limitation due to co-occurring symptoms of pain and emotional distress. Significant predictors of severe functional limitation due to co-occurring symptoms included age ≥ 80y (ref: 66-69y, adjusted relative risk (aRR): 1.74; 95% confidence interval (CI) 1.39-2.18, p < .001), stage IV disease at diagnosis (ref: stage I, aRR: 2.08; CI 1.52-2.86, p < .001), and lung cancer (ref: breast cancer, aRR: 1.84; CI 1.30-2.61, p < .001). Among 892 participants reporting co-occurring symptoms, 32.5% received neither pain nor emotional distress prescription medication. CONCLUSIONS: Functional limitation due to pain and emotional distress persist among older adults with cancer, particularly octogenarians. Efforts to identify and target unmet supportive care needs to maintain functional independence are needed.

Lidocaine infusion for pain control has been used for years. While some centers transition from continuous infusion lidocaine to oral mexiletine, there are no published studies to guide this conversion in pain and palliative care settings. This is a retrospective case series of 10 cancer patients across four institutions, with attention to dosing of both agents, and subsequent decrease in morphine-equivalent daily dosing (MEDD). The mean age was 55 years (range 34-78). The mean bolus dose of lidocaine was 1.6 mg/kg, infused over an average of 24 minutes, followed by a mean continuous infusion rate of 1.1 mg/kg/hr, and the infusion was continued for an average of 14.1 hours (range of 0.2 - 28 hours). The mean starting daily mexiletine dose was 400 mg (in 2-3 divided doses) and final dosing averaged 500 mg/day. The mean MEDD prior to starting lidocaine was 1118 mg/24 hours, which, by the time of final mexiletine dosing, was 882 mg/24 hours, a 21% MEDD reduction. The average hospital length of stay was 14 days. There was no lidocaine-induced toxicity and no lidocaine levels were obtained. Two of the 10 patients stopped mexiletine early, one from confusion four days after initiation of mexiletine, and the other after six weeks due to dizziness and visual changes. For cancer patients with suboptimal pain control on large doses of opioid, lidocaine infusion followed by oral mexiletine was well tolerated and effective.

CONTEXT: Older adults with advanced lung cancer experience high symptom burden at end of life (EOL), yet hospice enrollment often happens late or not at all. Receipt of medications to manage symptoms in the outpatient setting, outside the Medicare hospice benefit, has not been described. OBJECTIVES: We examined patterns of symptom management medication receipt at EOL for older adults who died of lung cancer. METHODS: This retrospective cohort used the Surveillance, Epidemiology, and End Results-Medicare database to identify decedents diagnosed with lung cancer at age 67 years and older between January 2008 and December 2013 who survived six months and greater after diagnosis. Using Medicare Part B and D claims, we identified monthly receipt of outpatient medications for symptomatic management of pain, emotional distress, fatigue, dyspnea, anorexia, and nausea/vomiting. Multivariable logistic regression estimated associations between medication receipt and patient demographic characteristics, comorbidity, and concurrent therapy. RESULTS: Of the 16,246 included patients, large proportions received medications for dyspnea (70.7%), pain (62.5%), and emotional distress (49.4%), with lower prevalence for other symptoms. Medication receipt increased from six months to one month before death. Women and dual Medicaid enrolled were more likely to receive medications for pain, emotional distress, dyspnea, and nausea/vomiting. Receipt of symptom management medications decreased with increasing age and racial/ethnical minorities. CONCLUSION: Symptom management medication receipt was common and increasing toward EOL. Lower use by males, older adults, and nonwhites may reflect poor access or poor patient-provider communication. Further research is needed to understand these patterns and assess adequacy of symptom management in the outpatient setting.

Evidence guiding inpatient management of buprenorphine is lacking-this retrospective cohort study evaluated the clinical impact of hospital continuation versus discontinuation of buprenorphine at an academic medical center. The primary outcome was inpatient oral morphine equivalents (OME). Secondary outcomes included patient pain levels, functional assessment, and hospital length of stay. One hundred thirty-one patients (74 continued buprenorphine, 57 discontinued) were included in the analysis. Median OME were significantly lower among patients continued on buprenorphine versus discontinued (11 mg vs 103 mg, p < 0.001), as was maximum 24-hour opioid utilization (60 mg vs 240 mg, p < 0.001) and 24-hour pre-discharge utilization (10 mg vs 128 mg, p < 0.001). Median pain levels were similar between groups at the time of admission (8 in each group, p = 0.48), discharge (7 in each group, p = 0.26), and over the first 7 days of hospitalization (7 vs 8, p = 0.08). Hospital length of stay was similar between groups (5 days in each group, p > 0.99). Failure to reinitiate buprenorphine occurred in 31/57 patients (54.4%) in the discontinuation group. Hospital buprenorphine continuation is associated with reduced opioid requirements, while not significantly impacting pain levels, functionality, or length of admission. Failure to reinitiate buprenorphine was common and may have negative implications for addiction treatment.

CONTEXT:: The effect of methadone on corrected QT interval (QTc) in patients with cancer pain is not well-known. OBJECTIVES:: To describe and characterize the effect of low-, moderate-, and high-dose enteral methadone on QTc interval in patients with cancer. METHODS:: Retrospective cohort study including patients prescribed enteral methadone during the 27-month study period. Participants were divided into 3 methadone daily dose groups: <30 (low dose), 30 to 59 (moderate dose), ≥60 (high dose) mg. The primary outcome was the incidence of QTc prolongation (>450 ms for females and >430 ms for males). Secondary outcomes included the magnitude of change in QTc after starting methadone, the incidence of clinically significant QTc prolongation (>500 ms) and the prevalence of torsades de pointes and syncope. RESULTS:: Two hundred three patients met study inclusion criteria: 91 (45%) low dose, 52 (26%) moderate dose, and 60 (29%) high dose. Incidence of QTc prolongation for low-, moderate-, and high-dose groups was 50 (55%), 37 (71%), and 43 (72%), respectively ( P = .039, low vs high dose). Incidence of clinically significant QTc prolongation was 10 (11%), 4 (8%), and 7 (12%) for low-, moderate-, and high-dose groups. For patients without QTc prolongation prior to initiating methadone, 62% of moderate-dose patients and 67% of high-dose patients had QTc prolongation, while taking methadone. CONCLUSION:: This study found a notably high incidence of QTc prolongation in patients with cancer using enteral methadone. Future studies should aim to determine the risk of adverse cardiac effects in the cancer population and determine appropriate monitoring of methadone for pain management.
