The Prescription Opioids and Depression Pathways Cohort Study

Characteristics of Patients with Non-Cancer Pain and Perceived Severity of COVID-19 Related Stress

Synopsis Patients with non-cancer pain reported increased pain and pain interference during the first months of the COVID-19 pandemic. We determined if pain, prescription opioid use, and comorbidities were associated with perceived COVID-19-related stress as the pandemic peaked. Analysis of survey data revealed that depression/anxiety, pain severity, and pain interference were most strongly and consistently associated with greater stress due to COVID-19 related changes in lifestyle, worsening of emotional/mental health and worsening pain. Identifying specific stressful experiences that most impacted patients with non-cancer pain may help target public health and treatment interventions.

BACKGROUND

During the first months of the COVID-19 pandemic, patients with chronic pain reported increased pain severity and interference. This study measured the association between pain, prescription opioid use, and comorbidities with perceived COVID-19-related stress as the pandemic peaked in the United States.

METHODS

From 9/2020 to 3/2021, the first 149 subjects from a prospective cohort study of non-cancer pain, completed a survey which contained the Complementary and Integrative Research (CAIR) Pandemic Impact Questionnaire (C-PIQ). Respondents also reported whether the pandemic has contributed to their pain or opioid use. Bivariate comparisons explored patient characteristics with each CAIR domain.

RESULTS

Respondents mean age was 54.6 (±11.3) years, 69.8% were female, 64.6% were White. Respondent characteristics were not associated with reading/watching/thinking about the pandemic or with worry about health. Depression/anxiety (p=0.003), using any prescription opioid in the prior three months (p=0.009), higher morphine milligram equivalent used (p=0.005), higher pain severity (p=0.011), and higher pain interference (p=0.0004) were all positively and significantly associated with moderate to severe stress due to COVID-19 related lifestyle changes. Depression/anxiety, pain severity, and pain interference were positively associated with COVID-19-related worsening emotional/mental health. Depression/anxiety were significantly (p<0.0001) associated with reporting that the pandemic made their pain worse.

CONCLUSION

Depression, anxiety, pain severity, and pain interference were most strongly and consistently associated with COVID-19 changes in way of life, worsening of emotional/mental health, and worsening pain. Identifying specific stressful experiences that most impacted patients with noncancer pain may inform public health and treatment interventions.

Anxiety and Fear Avoidance Beliefs and Behavior May Be Significant Risk Factors for Chronic Opioid Analgesic Therapy Reliance for Patients with Chronic Pain-Results from a Preliminary Study

OBJECTIVE

To describe differences between patients with chronic, non-cancer pain (CNCP) who were successfully able to cease full mu agonist chronic opioid analgesic therapy (COAT), and those who exhibited refractory COAT reliance, among those who participated in a multidisciplinary program designed for COAT cessation.

DESIGN

A retrospective review of electronic medical records (EMR) data was organized for preliminary analysis.

SETTING

A multicenter private practice specializing in CNCP, which received patient referrals from the surrounding geographical area of primary and specialty care offices in Northern California.

SUBJECTS

Data from 109 patients with CNCP who participated in a multidisciplinary program to cease COAT between the dates of October 2017 to December 2019 were examined.

METHODS

EMR data, pre-COAT cessation, of oral morphine milligram equivalence (MME) and validated questionnaire responses assessing anxiety and fear-based beliefs and behavior, as well as opioid misuse, were extracted and compared between those who successfully ceased COAT and those who did not.

RESULTS

Patients who were unsuccessful at COAT cessation reported significantly higher Fear Avoidance Beliefs Questionnaire (FAB) scores. No significant differences were found based on incoming MME amounts, Current Opioid Misuse Measure (COMM) or Tampa Scale of Kinesiophobia (TSK) scores. Pain Catastrophizing Scale (PCS) scores showed a split pattern with unclear significance.

CONCLUSIONS

Results suggest that fear avoidance beliefs and behavior, as measured by the FAB, play a significant role in refractory COAT reliance for patients with CNCP.

Prevalence and Trends of Opioid Use in Patients With Depression in the United States

Background Depression and prescription opioid use have a bi-directional relationship. Depression commonly co-occurs with chronic noncancer pain and is known to be associated with opioid use. Studies have found an increased risk of depression only in patients with opioid dependence. Other studies have found an increased risk of opioid misuse in depressed patients. In addition, chronic pain conditions can lead to depression without the use of opioids. Methods We used the National Health and Nutrition Examination Survey (NHANES) data collected over seven survey cycles spanning 14 years: 2005/2006-2017/2018. Included in our study were participants ≥18 years who completed the patient health (PHQ-9) questionnaire. Persons with documented use of opioids were considered to have chronic use of opioids. Relevant data files were merged, and analytical weights computed in keeping with the survey analytical guidelines. Prevalence measures are reported as proportions. Associations were assessed using the Chi-square test. Binary logistic regression was used to assess the trend in the prevalence of opioid use. We used STATA-16 for data analysis and p-values <0.05 were considered statistically significant. Results A total of 36,459 participants met the inclusion criteria. The prevalence of depression was 7.7% (95% CI: 7.3-8.2). The prevalence of any narcotic use was 6.0%. Among depressed individuals, Blacks: OR 0.71 (95% CI: 0.54-0.93) and Hispanics: OR 0.48 (95% CI: 0.34-0.67) were less likely to be on narcotics compared to non-Hispanic Whites. The prevalence of opioid use was stable over the first 12 years, followed by a significant drop in the last two years. Conclusion Beyond the risk for opioid misuse, and opioid use disorder, depression should also be considered when prescribing opioids. It is therefore important to implement a training to screen for depression in patients receiving opioids for pain management.
