Opioid Epidemic or Pain Crisis? Using the Virginia All Payer Claims Database to Describe Opioid Medication Prescribing Patterns and Potential Harms for Patients With Cancer

PURPOSE: A key challenge regarding the current opioid epidemic is understanding how concerns regarding opioid-related harms affect access to pain management, an essential element of cancer care. In certain regions of the United States where disproportionately high cancer mortality and opioid fatality rates coexist (such as southwest Virginia in central Appalachia), this dilemma is particularly pronounced. METHODS: This longitudinal, exploratory, secondary analysis used the Commonwealth of Virginia All Payer Claims Database to describe prescription opioid medication (POM) prescribing patterns and potential harms for adult patients with cancer living in rural southwest Virginia between 2011 and 2015. Descriptive and inferential statistical analyses were conducted at the patient, prescriber, and prescription levels to identify patterns and predictors of POM prescribing and potential harms. To explore geographic patterns, choropleth and heat maps were created. RESULTS: Of the total sample of patients with cancer (n = 4,324), less than 25% were prescribed a Controlled Substance Schedule II POM at least three times in any study year. More than 60% of patients never received a Controlled Substance Schedule II POM prescription. Six hundred fifty-two patients (15.1%) experienced 1,599 hospitalizations for any reason; 10 or fewer patients were admitted for 11 opioid use disorder–related hospitalizations. The main findings suggest potential undertreatment of cancer-related pain; no difference in risk for opioid-related hospitalization on the basis of frequency of POM prescriptions; and geographic disparities where opioid overdoses are occurring versus where POM prescription use is highest. CONCLUSION: These findings have significant opioid policy and practice implications related to the need for cancer-specific prescribing guidelines, how to optimally allocate health delivery services, and the urgent need to improve data interoperability and access related to POMs.

Optimizing the Care of Malignant Bowel Obstruction in Patients With Advanced Gynecologic Cancer

PURPOSE: Malignant bowel obstruction (MBO) is a common and distressing complication in women with advanced gynecologic cancer. A pilot, interprofessional MBO program was launched in 2016 at a large Canadian tertiary cancer center to integrate these patients’ complex care needs across multiple disciplines and support women with MBO. METHOD: Retrospective analysis to evaluate the outcomes of women with advanced gynecologic cancer who were admitted to hospital because of MBO, before (2014 to 2016: baseline group) and after (2016 to 2018) implementation of the MBO program. RESULTS: Of the 169 women evaluated, 106 and 63 were in the baseline group and MBO program group, respectively. Most had ovarian cancer (n = 124; 73%) and had small-bowel obstruction (n = 131; 78%). There was a significantly shorter cumulative hospital length of stay (LOSsum) within the first 60 days of MBO diagnosis in the MBO program group compared with the baseline group (13 v 22 days, respectively; adjusted P = .006). The median overall survival for women treated in the MBO program was also significantly longer compared with the baseline group (243 v 99 days, respectively; adjusted P = .002). Using the interprofessional MBO care platform, a greater proportion of patients received palliative chemotherapy (83% v 56%) and less surgery (11% v 21%) in the MBO program group than in the baseline group, respectively. A subgroup of women (n = 11) received total parenteral nutrition for longer than 6 months. CONCLUSION: Implementation of a comprehensive, interprofessional MBO program significantly affects patient care and may improve outcomes. Unique to this MBO program is an integrated outpatient model of care and education that empowers patients to recognize MBO symptoms for early intervention.

Oncologic Implications of Chronic Hepatitis C Virus Infection

Chronic hepatitis C virus (HCV) infection increases the risk for several types of cancer, including hepatocellular carcinoma (HCC) and B-cell non-Hodgkin lymphoma, as primary and second primary malignancies. HCV-infected patients with cancer, particularly those undergoing anticancer therapy, are at risk for development of enhanced HCV replication, which can lead to hepatitis flare and progression of liver fibrosis or cirrhosis. Risk factors for HCV infection include injection drug use, blood transfusion, or solid organ transplantation before 1992, receipt of clotting factor concentrates before 1987, long-term hemodialysis, chronic liver disease, HIV positivity, and occupational exposure. Widely available direct-acting antivirals are highly effective against HCV and well tolerated. Identification of HCV-infected individuals is the essential first step in treatment and eradication of the infection. One-time screening is recommended for persons born from 1945 to 1965; screening is also recommended for persons with risk factors. Recently, a public health recommendation has been drafted to screen all adults age 18 to 79 years. Two oncology organizations recommend screening all patients with hematologic malignancies and hematopoietic cell transplant recipients, and a recently published multicenter prospective study supports universal HCV screening for all patients with cancer. HCV screening entails testing for anti-HCV antibodies in serum and, when results are positive, HCV RNA quantitation to confirm infection. Direct-acting antiviral therapy eradicates HCV in almost all cases. Virologic cure of HCV prevents chronic hepatitis and progression to liver fibrosis or cirrhosis. HCV eradication also decreases the risk of developing HCV-associated primary and second primary malignancies, and it may allow HCV-infected patients access to important cancer clinical trials. Patients with HCV-related cirrhosis require lifelong surveillance for HCC, even after viral eradication.
