Implementation of a pharmacy consult to reduce co-prescribing of opioids and benzodiazepines in a Veteran population

Impact of narcotics information management system on inappropriate benzodiazepine receptor agonist prescriptions: A quasi-experimental analysis in South Korea

AIMS

The South Korean government implemented the narcotics information management system (NIMS) on 18 May 2018 to manage benzodiazepine receptor agonists (BzRAs) and narcotics effectively and establish a reporting mechanism for these drugs. This study assessed the effects of NIMS on inappropriate use of BzRAs.

METHODS

Using national patient sample data from 2016 to 2020, we analysed adult outpatients who were prescribed oral BzRAs. We conducted a time series and segmented regression analysis using selected indicators to analyse the monthly variations related to the inappropriate use of these medications.

RESULTS

The study revealed no significant changes in the indicators of inappropriate BzRA use following the NIMS implementation. Contrary to expectations, there was a significant increase in the proportion of patients exceeding defined daily dose (DDD) and in those receiving concurrent prescriptions of multiple BzRAs, following the implementation of NIMS. The immediate impact of the COVID-19 pandemic was an increase in DDD exceedance; however, overall, this did not significantly affect BzRA use.

CONCLUSIONS

The introduction of NIMS did not significantly enhance the management of BzRA misuse. Additional measures, including continuous monitoring, system improvements and comprehensive education for prescribers and patients, are recommended to ensure the appropriate use of psychotropic medications.

Evaluating Outcomes of a Pharmacist-Driven Pain Management Consult Service

The opioid crisis continues to place a significant burden on American families and the healthcare system. To date, there is an evolving body of evidence demonstrating that pharmacists can positively impact patient care in the pain management specialty. The purpose of this study is to evaluate 24-hour average pain scores before and after a clinical pharmacist completes a physician-ordered pain consult in a community hospital setting. For the primary outcome, there was a statistically significant reduction in pain scores 48 hours post consult (6.5 vs. 5.2; p < 0.001; Table 3) and 24 hours prior to discharge (6.1 vs. 4.5; p < 0.001; Table 3) when compared to pain scores 24 hours prior to consult. Additionally, there was a statistically significant reduction in the number of morphine milligram equivalents (MMEs) at 48 hours post consult (149.4 vs. 133.8; p < 0.001; Table 4) and 24 hours prior to discharge (136.5 vs. 100.6; p < 0.001; Table 4) when compared to 24 hours prior to consult. This pharmacist-driven pain consult service demonstrated a statistically significant reduction in pain scores while simultaneously reducing MME utilization and the number of opioids ordered, using a multimodal evidence-driven approach to pain management in a community hospital.

Opioid-related emergency department visits and hospitalizations among patients with chronic gastrointestinal symptoms and disorders dually enrolled in the Department of Veterans Affairs and Medicare Part D

PURPOSE

We examined the prevalence of, and factors associated with, serious opioid-related adverse drug events (ORADEs) that led to an emergency department (ED) visit or hospitalization among patients with chronic gastrointestinal (GI) symptoms and disorders dually enrolled in the Department of Veterans Affairs (VA) and Medicare Part D.

METHODS

In this retrospective cohort study, we used linked national patient-level data (April 1, 2011, to October 31, 2014) from the VA and Centers for Medicare and Medicaid Services to identify serious ORADEs among dually enrolled veterans with a chronic GI symptom or disorder. Outcome measures included serious ORADEs, defined as an ED visit attributed to an ORADE or a hospitalization where the principal or secondary reason for admission involved an opioid. We used multiple logistic regression models to determine factors independently associated with a serious ORADE.

RESULTS

We identified 3,430 veterans who had a chronic GI symptom or disorder; were dually enrolled in the VA and Medicare Part D; and had a serious ORADE that led to an ED visit, hospitalization, or both. The period prevalence of having a serious ORADE was 2.4% overall and 4.4% among veterans with chronic opioid use (≥90 consecutive days). Veterans with serious ORADEs were more likely to be less than 40 years old, male, white, and to have chronic abdominal pain, functional GI disorders, chronic pancreatitis, or Crohn's disease. They were also more likely to have used opioids chronically and at higher daily doses.

CONCLUSION

There may be a considerable burden of serious ORADEs among patients with chronic GI symptoms and disorders. Future quality improvement efforts should target this vulnerable population.

Impact of Implementing an Academic Detailing Program on Opioid-Benzodiazepine Co-Prescribing Trends at the U.S. Department of Veterans Affairs

OBJECTIVES

To assess the process and outcomes of academic detailing to enhance the Opioid Safety Initiative and the Psychotropic Drug Safety Initiative to reduce co-prescribing of opioid-benzodiazepine combinations in veterans.

METHODS

A retrospective cohort design was conducted to evaluate the impact of implementing an academic detailing program on opioid-benzodiazepine co-prescribing between October 2014 through March 2019 at the U.S. Department of Veterans Affairs (VA). The primary outcome was the monthly prevalence of veterans (number per 1,000 population) who were co-prescribed opioid-benzodiazepine combination. Process measure was evaluated using implementation reach (proportion of providers who received academic detailing). Station-level analysis was performed using a linear fixed effects regression model to evaluate the rate of change in the prevalence of veterans co-prescribed opioid-benzodiazepine.

RESULTS

Altogether 130 VA stations was included for analysis; 119 stations implemented opioid-related or benzodiazepine-related academic detailing, and 11 stations did not. Stations that had implemented academic detailing had a 33% greater monthly reduction on the opioid-benzodiazepine co-prescribing prevalence compared to stations that did not implement academic detailing (P = .036). In the linear fixed effects regression model, stations that were expected to have 100% of providers exposed to academic detailing were statistically associated with a greater decrease in the monthly prevalence of Veterans co-prescribed opioid-benzodiazepine by 4.9 veterans per 1,000 population (P < .001) compared to stations with 0% of providers exposed to academic detailing.

CONCLUSIONS

Stations that implemented academic detailing and had a higher proportion of providers who were exposed to opioid- or benzodiazepine-related academic detailing had a significant decrease in the monthly prevalence of Veterans co-prescribed opioid-benzodiazepine combinations.

Opioid stewardship: implementing a proactive, pharmacist-led intervention for patients coprescribed opioids and benzodiazepines at an urban academic primary care centre

In 2017, almost 4000 Canadians died from opioid-related causes. Coadministration of opioids and benzodiazepines is a risk factor for overdose. Few studies have evaluated leveraging pharmacists to address opioid-benzodiazepine coprescribing. Our aim was to develop and test a role for pharmacists as opioid stewards, to reduce opioid and benzodiazepine doses in coprescribed patients. We conducted Plan-Do-Study-Act cycles between November 2017 and May 2018 across two primary care centre clinics. A third clinic acted as a control. Our intervention included a pharmacist: (1) identifying patients through medical record queries; (2) developing care plans; (3) discussing recommendations with physicians and (4) discussing implementing recommendations. We refined the intervention according to patient and physician feedback. At the intervention clinics, the number of patients with pharmacist developed care plans increased from less than 20% at baseline to over 60% postintervention. There was also a fourfold increase in the number of patients with an active opioid taper. At the control clinic, the number of patients with pharmacist developed care plans remained relatively stable at less than 20%. The number of patients with active opioid tapers remained zero. At the intervention clinics, mean daily opioid dose decreased 11% from 50.5 milligrams morphine equivalent (MME) to 44.7 MME. At the control clinic, it increased 15% from 62.3 MME to 71.4 MME. The number of patients with a benzodiazepine taper remained relatively stable at both the intervention and control clinics at less than 20%. At the intervention clinics, mean daily benzodiazepine dose decreased 8% from 9.9 milligrams diazepam equivalent (MDE) to 9.3 MDE. At the control clinic, it decreased 4% from 10.8 MDE to 10.4 MDE. A proactive, pharmacist-led intervention for coprescribed patients increased opioid tapers and decreased opioid and benzodiazepine doses. Future work will help us understand whether sustaining the intervention ultimately reduces rates of opioid-benzodiazepine coprescribing.

Misalignment of Stakeholder Incentives in the Opioid Crisis

The current opioid epidemic has killed more than 446,000 Americans over the past two decades. Despite the magnitude of the crisis, little is known to what degree the misalignment of incentives among stakeholders due to competing interests has contributed to the current situation. In this study, we explore evidence in the literature for the working hypothesis that misalignment rooted in the cost, quality, or access to care can be a significant contributor to the opioid epidemic. The review identified several problems that can contribute to incentive misalignment by compromising the triple aims (cost, quality, and access) in this epidemic. Some of these issues include the inefficacy of conventional payment mechanisms in providing incentives for providers, practice guidelines in pain management that are not easily implementable across different medical specialties, barriers in adopting multi-modal pain management strategies, low capacity of providers/treatments to address opioid/substance use disorders, the complexity of addressing the co-occurrence of chronic pain and opioid use disorders, and patients' non-adherence to opioid substitution treatments. In discussing these issues, we also shed light on factors that can facilitate the alignment of incentives among stakeholders to effectively address the current crisis.

Community pharmacists and chronic pain: A qualitative study of experience, perception, and challenges

Background: Patients suffering from chronic pain frequently ask pharmacists for advice.

Aims: This study was prompted by inadequacies in the available body of literature reporting on pharmacists’ experiences with providing care for patients with chronic pain in the community setting.

Methods: A qualitative investigation of Ontario community pharmacists’ experiences was carried out. Participants were interviewed using a semistructured guide. Interviews were analyzed using thematic analysis, influenced by grounded theory.

Results: This study revealed that pharmacists were knowledgeable and empathetic toward patient concerns. Challenges in their role included financial factors, patient access to multimodal treatment options, potential for harm associated with opioid use, inadequate monitoring, and gaps in training.

Conclusions: This study reports community and Family Health Team pharmacists’ experiences caring for patients with chronic pain and perceptions of their professional role, including strengths and limitations, and identifies perceived challenges in the health care system.

Correlates of Benzodiazepine Use and Adverse Outcomes Among Patients with Chronic Pain Prescribed Long-term Opioid Therapy

OBJECTIVE

To examine the correlates and odds of receiving overlapping benzodiazepine and opioid prescriptions and whether co-prescription was associated with greater odds of falling or visiting the emergency department.

DESIGN

Cross-sectional study.

SETTING

A large private integrated health system and a Veterans Health Administration integrated health system.

SUBJECTS

Five hundred seventeen adults with musculoskeletal pain and current prescriptions for long-term opioid therapy.

METHODS

A multivariate logistic regression model examined correlates of having overlapping benzodiazepine and opioid prescriptions in the year before enrollment in the cross-sectional study. Negative binomial models analyzed the number of falls in the past three months and past-year emergency department visits. In addition to propensity score adjustment, models controlled for demographic characteristics, psychiatric diagnoses, medications, overall comorbidity score, and opioid morphine equivalent dose.

RESULTS

Twenty-five percent (N = 127) of participants had co-occurring benzodiazepine and opioid prescriptions in the prior year. Odds of receiving a benzodiazepine prescription were significantly higher among patients with the following psychiatric diagnoses: anxiety disorder (adjusted odds ratio [AOR] = 4.71, 95% confidence interval [CI] = 2.67-8.32, P < 0.001), post-traumatic stress disorder (AOR = 2.24, 95% CI = 1.14-4.38, P = 0.019), and bipolar disorder (AOR = 3.82, 95% CI = 1.49-9.81, P = 0.005). Past-year overlapping benzodiazepine and opioid prescriptions were associated with adverse outcomes, including a greater number of falls (risk ratio [RR] = 3.27, 95% CI = 1.77-6.02, P = 0.001) and emergency department visits (RR = 1.66, 95% CI = 1.08-2.53, P = 0.0194).

CONCLUSIONS

Among patients with chronic pain prescribed long-term opioid therapy, one-quarter of patients had co-occurring prescriptions for benzodiazepines, and dual use was associated with increased odds of falls and emergency department visits.

Naloxone coprescription in U.S. ambulatory care centers and emergency departments

OBJECTIVES

The rise in both drug overdoses and deaths owing to opioids has been increasing for at least 2 decades in the United States. Naloxone-prescribing programs have been in use since the mid-2000s with a guideline to manage their use being published in 2012. This study seeks to determine the national prevalence of naloxone coprescribing within U.S. ambulatory care centers and emergency departments (EDs).

METHODS

This study was a retrospective, cross-sectional, observational analysis of data collected by the Centers for Disease Control and Prevention (CDC) in the National Ambulatory Medical Care Survey and National Hospital Ambulatory Medical Care Survey: Emergency Department Summary during the years 2012-2016. All survey participants aged 18 years or older with documented opioid use-with the exception of codeine, dihydrocodeine, and opioid-containing cough syrups-were included. Variables of interest that were available in the data were summarized.

RESULTS

Naloxone was coprescribed with opioids in less than 0.1% of visits. Despite 5 years of data combined across 2 national surveys including 48,158 adults with documented opioid use, further analyses of naloxone coprescription could not be performed owing to the limited number of such coprescriptions. Among the factors previously documented to increase the risk of opioid overdose, concurrent benzodiazepine use (18.7%) was the most reported, followed by history of substance use disorder (1.6%) and history of overdose (< 0.1%).

CONCLUSION

Using nationally representative data collected by the CDC from ambulatory care centers and EDs, we found that naloxone was coprescribed with opioids in only less than 0.1% of visits. Future research is warranted to determine whether current practices have adapted to meet the standards set by the 2016 CDC guidelines.

Patient care activities by community pharmacists in a capitation funding model mental health and addictions program

BACKGROUND

Community pharmacists are autonomous, regulated health care professionals located in urban and rural communities in Canada. The accessibility, knowledge, and skills of community pharmacists can be leveraged to increase mental illness and addictions care in communities.

METHODS

The Bloom Program was designed, developed, and implemented based on the Behaviour Change Wheel and a program of research in community pharmacy mental healthcare capacity building. We evaluated the Bloom Program as a demonstration project using mixed methods. A retrospective chart audit was conducted to examine outcomes and these are reported in this paper.

RESULTS

We collected 201 patient charts from 23 pharmacies in Nova Scotia with 182 patients having at least one or more follow-up visits. Anxiety (n = 126, 69%), depression (n = 112, 62%), and sleep disorders (n = 64, 35%) were the most frequent mental health problems. Comorbid physical health problems were documented in 57% (n = 104). The average number of prescribed medications was 5.5 (range 0 to 24). Sixty seven percent (n = 122) were taking multiple psychotropics and 71% (n = 130) reported taking more than one medication for physical health problems. Treatment optimization was the leading reason for enrollment with more than 80% seeking improvements in symptom management and daily functioning. There were a total of 1233 patient-care meetings documented, of which the duration was recorded in 1098. The median time for enrolling, assessing, and providing follow-up care by pharmacists was 142 min (mean 176, SD 128) per patient. The median follow-up encounter duration was 15 min. A total of 146 patient care encounters were 60 min or longer, representing 13.3% of all timed encounters.

CONCLUSIONS

Pharmacists work with patients with lived experience of mental illness and addictions to improve medication related outcomes including those related to treatment optimization, reducing polytherapy, and facilitating withdrawal from medications. Pharmacists can offer their services frequently and routinely without the need for an appointment while affording patient confidentiality and privacy. Important roles for pharmacists around the deprescribing of various medications (e.g., benzodiazepines) have previously been supported and should be optimized and more broadly implemented. Further research on the best mechanisms to incentivize pharmacists in mental illness and addiction's care should be explored.

Emergency Department Provider Perspectives on Benzodiazepine-Opioid Coprescribing: A Qualitative Study

OBJECTIVE

Benzodiazepines and opioids are prescribed simultaneously (i.e., "coprescribed") in many clinical settings, despite guidelines advising against this practice and mounting evidence that concomitant use of both medications increases overdose risk. This study sought to characterize the contexts in which benzodiazepine-opioid coprescribing occurs and providers' reasons for coprescribing.

METHODS

We conducted focus groups with emergency department (ED) providers (resident and attending physicians, advanced practice providers, and pharmacists) from three hospitals using semistructured interviews to elicit perspectives on benzodiazepine-opioid coprescribing. Discussions were audio-recorded and transcribed. We performed qualitative content analysis of the resulting transcripts using a consensual qualitative research approach, aiming to identify priority categories that describe the phenomenon of benzodiazepine-opioid coprescribing.

RESULTS

Participants acknowledged coprescribing rarely and reluctantly and often provided specific discharge instructions when coprescribing. The decision to coprescribe is multifactorial, often isolated to specific clinical and situational contexts (e.g., low back pain, failed solitary opioid therapy) and strongly influenced by a provider's beliefs about the efficacy of combination therapy. The decision to coprescribe is further influenced by a self-imposed pressure to escalate care or avoid hospital admission. When considering potential interventions to reduce the incidence of coprescribing, participants opposed computerized alerts but were supportive of a pharmacist-assisted intervention. Many providers found the process of participating in peer discussions on prescribing habits to be beneficial.

CONCLUSIONS

In this qualitative study of ED providers, we found that benzodiazepine-opioid coprescribing occurs in specific clinical and situational contexts, such as the treatment of low back pain or failed solitary opioid therapy. The decision to coprescribe is strongly influenced by a provider's beliefs and by self-imposed pressure to escalate care or avoid admission.

National trends in long-term use of prescription opioids

PURPOSE

This study examined recent trends and correlates of prescription opioid use and long-term use in the United States.

METHODS

Data were from 47 356 adult participants of National Health and Nutrition Survey from 1999-2000 to 2013-2014. Participants were asked about prescription medications used in the past 30 days. Long-term use of prescription opioids was defined by use for 90 days or longer.

RESULTS

The prevalence of prescription opioid use increased from 4.1% of US adults in 1999-2000 to 6.8% in 2013-2014 (odds ratio [OR] = 1.38, 95% confidence interval [CI] = 1.10-1.75, P = .007). This trend was driven by a sharp increase in long-term use which increased from 1.8% to 5.4% (OR = 2.22, 95% CI = 1.65-3.00, P < .001). Of all opioid users in 2013-2014, 79.4% were long-term users compared with 45.1% in 1999-2000. Long-term use was associated with poorer physical health, concurrent benzodiazepine use, and history of heroin use.

CONCLUSIONS

The findings highlight the need for research on potential benefits and harms of long-term use of opioids and efforts to restrict long-term use to patients for whom the benefits outweigh the risks.
