Evidence-based pain medicine for primary care physicians

Synthesis of clinical practice guideline recommendations for the primary health care of chronic musculoskeletal pain

RATIONALE AND AIMS

The prevalence of chronic musculoskeletal pain (CMSP) is high and rising. The multidimensional impact of CMSP on individuals necessitates multidisciplinary evidence-based strategies to prevent and manage chronic pain. Primary health care (PHC) is the first point of care in many healthcare systems and evidence implementation at this point is important. We aim to describe the process of development of a comprehensive list of evidence-based recommendations derived from different high-quality clinical practice guidelines (CPGs) to inform the PHC healthcare of adults with CMSP.

METHOD

A systematic review was conducted of CPGs that focussed on PHC management of CMSP in adults. CPGs were identified by searching 13 guideline clearinghouses and five online databases. Eligible CPGs were critically appraised using Appraisal of Guidelines Research and Evaluation, Version II (AGREE II). A stepwise systematic process was followed to identify a core set of recommendations. This process comprised the following: extract recommendations; analyze recommendations; synthesize recommendations by assimilating similar recommendations; determine the strength of the body of evidence underpinning the recommendations and produce a list of synthesized recommendations.

RESULTS

Six high-quality CPGs were identified, providing 156 recommendations. These were condensed to 42 statements covering topics about the approach to care, assessment, advice and education, referral, pharmacological management, physical therapy, electrotherapy, psychological therapy, complementary therapy and self-management. The set of recommendations encompasses a person-centered approach, collaborative decision making, a biopsychosocial approach, patient education and empowerment towards self-management.

CONCLUSION

The process of developing composite recommendations from multiple CPGs enables end-users to access comprehensive information on managing CMSP in PHC settings that is not available from one singular CPG. The content and evidence base for recommendations varied between CPGs. A similar stepwise process may be used to develop a core set of recommendations for other health conditions, where multiple, diverse CPGs exist.

Academic detailing increases prescription drug monitoring program use among primary care practices

OBJECTIVE

Clinical review of a prescription drug monitoring program (PDMP) is considered a valuable tool for opioid prescribing risk mitigation; however, PDMP use is often low, even in states with mandatory registration and use policies. The objective was to evaluate the impact of an academic detailing (AD) outreach intervention on PDMP use among primary care prescribers.

METHODS

AD intervention was delivered to primary care based controlled substance prescribers (N = 87) and their associated PDMP delegates (n = 42) by a clinical pharmacist as 1 component of a large-scale, statewide initiative to improve opioid prescribing safety. Prescriber PDMP use behavior was assessed by prescriber self-report and analysis of objective 2016-2018 PDMP data regarding the number of monthly report requests. We compared means between pre- and postintervention using a paired t test and plotted the monthly average reports over time to assess the trend of mean reports over time. Generalized linear mixed model with a negative binomial distribution was used to assess the difference in the trend and magnitude of the combined count of reports for the entire sample and prescriber subsets that were segmented on the basis of the adoption status of PDMP.

RESULTS

The monthly mean of reports by combined prescribers and delegates significantly increased after the AD intervention (mean 28.1 pre vs. 53.0 post; P < 0.001), with the increase in delegate reports (mean 17.1 pre vs. 60.0 post; P < 0.001) driving the overall increase. Reports were requested 40.4 times more often than in the preintervention period (P < 0.001). Patterns of pre- to postchanges in mean monthly report requests differed by baseline PDMP adoption status.

CONCLUSION

The AD intervention was transformative in facilitating practice change to use delegates to run reports. Visits with both prescribers and delegates, including hands-on PDMP training and registration assistance, can be viewed as beneficial for practice facilitation.

Barriers and Facilitators to the Prevention of Chronic Pain in the Subacute Phase After Cardiac Surgery

BACKGROUND

Although a transitional approach promoting continuity of care is warranted to prevent chronic post-surgical pain (CPSP) and opioid misuse, there is limited research examining interventions targeting the subacute phase after cardiac surgery. Contextual multi-level factors may explain this scarcity.

AIMS

The purpose of this study was to explore the potential implementation of a nursing intervention to prevent CPSP in the subacute phase by describing nurses' viewpoints of current barriers and facilitators.

DESIGN

A descriptive qualitative study was conducted using secondary data analysis.

SETTINGS

A Web-based survey was used along with in-person interviews.

PARTICIPANTS

75 perioperative nurses.

METHODS

Qualitative data from individual interviews (n=10) and open-ended responses to a survey (n=65) regarding the intervention's acceptability were used. Content analysis was conducted using a deductive approach.

RESULTS

The introduction of nurses from various clinical settings to a new intervention allowed reflection on current practice and represented a shift toward a preventive approach. The main barrier expressed was the lack of communication and continuity of care between clinical settings. Several policy implications were outlined such as increasing the involvement of rehabilitation programs and strengthening collaboration between pain specialists and primary care providers.

CONCLUSIONS

Based on perceptions of nurses involved at different stages of the continuum, the findings provide a preliminary picture of clinical challenges and potential avenues for the prevention of CPSP in the subacute phase after cardiac surgery. An expanded pain management nursing role in primary care would allow earlier interventions and contribute to the prevention of CPSP for a tremendous number of patients undergoing surgeries.

Effect of an Online Reimbursement Application System on Prescribing of Lidocaine 5% Medicated Plaster in the Republic of Ireland

BACKGROUND

The lidocaine 5% medicated plaster, Versatis^®, has one therapeutic indication listed on the Summary of Product Characteristics-symptomatic relief of post-herpetic neuralgia (PHN) in adults. Increased expenditure on Versatis^® suggests that there is considerable off-label use. To support the appropriate use of Versatis^®, the Health Service Executive's Primary Care Reimbursement Service (PCRS) introduced a reimbursement application system for Versatis^® from 1 September 2017.

OBJECTIVE

The aim of this study was to investigate the effect of introducing a reimbursement application system on Versatis^® prescribing under the General Medical Services (GMS) scheme.

METHODS

This study was carried out using prescription dispensing data from the PCRS pharmacy claims database. We carried out segmented linear regression to assess changes in the Versatis^® prescribing rate per 1000 GMS eligible population, before and after the introduction of the online reimbursement application system.

RESULTS

The results of the segmented regression analysis show that there was a statistically significant level (- 4.91, p < 0.001) and trend change (- 0.69, p < 0.001) in the rate of Versatis^® prescribing post-introduction of the reimbursement application system. In the year prior to the introduction of the system, 2016, the annual GMS expenditure on Versatis^® lidocaine 5% patches was over €27 million, whereas the GMS expenditure in 2018 was reduced to just over €2 million.

CONCLUSION

In our study, a substantial decrease in the dispensing of Versatis^® was seen after the implementation of a reimbursement application system. Prescribing of Versatis^® should be restricted to patients with a diagnosis of PHN not only to reduce costs, but to ensure evidence-based use of this medication.

Predictors of long-term opioid use and opioid use disorder among construction workers: Analysis of claims data

BACKGROUND

Construction workers have high rates of work-related musculoskeletal disorders, which lead to frequent opioid use and opioid use disorder (OUD). This paper quantified the incidence of opioid use and OUD among construction workers with and without musculoskeletal disorders.

METHODS

We conducted a retrospective study using union health claims from January 2015 to June 2018 from 19,909 construction workers. Claims for diagnoses of chronic musculoskeletal disorders, acute musculoskeletal injuries, musculoskeletal surgery, and other conditions were linked to new opioid prescriptions. We examined the effects of high doses (≥50 morphine mg equivalents per day), large supply (more than 7 days per fill), long-term opioid use (60 or more days supplied within a calendar quarter), and musculoskeletal disorders, on the odds of a future OUD.

RESULTS

There were high rates (42.8% per year) of chronic musculoskeletal disorders among workers, of whom 24.1% received new opioid prescriptions and 6.3% received long-term opioid prescriptions per year. Workers receiving opioids for chronic musculoskeletal disorders had the highest odds of future OUD: 4.71 (95% confidence interval 3.09-7.37); workers prescribed long-term opioids in any calendar quarter had a nearly 10-fold odds of developing an OUD.

CONCLUSIONS

Among construction workers, opioids initiated for musculoskeletal pain were strongly associated with incident long-term opioid use and OUD. Musculoskeletal pain from physically demanding work is likely one driver of the opioid epidemic in occupations like construction. Prevention of work injuries and alternative pain management are needed for workers at risk for musculoskeletal injuries.

Quality improvement initiative for pain management practices in primary care

In the context of both chronic pain and opioid crises, this large-system quality improvement project sought to increase use of evidence-based multimodal pain management strategies. Primary care providers (PCPs) in internal medicine and family medicine identified as above-median prescribers of 30-day opioid supplies were selected for intervention. PCPs received individualized email letters showing their opioid prescribing patterns relative to peers and urging them to view an internal pain/opioid educational video and related system guidelines. The median number of patients receiving 30-day opioid supplies from our target PCPs decreased over a 24-month period. For cohort patients identified at baseline and remaining in treatment over time, those receiving opioid prescriptions decreased, and those receiving nonopioid prescriptions increased. Percentages of PCPs prescribing nonopioids for cohort patients increased over the first year and nonpharmacologic referrals increased in range. Our evidence suggests that PCPs who are higher opioid prescribers will change their practices voluntarily when given feedback about their opioid prescribing patterns relative to their peers, as well as education regarding evidence-based pain management and opioid prescribing.

Over-indebtedness and its association with pain and pain medication use

In developed countries, millions of households are over-indebted, and the number continues to rise. Studies have found an increased risk of adverse health effects among individuals that cannot cover payment obligations with available assets persistently. However, little is known about the role of over-indebtedness in pain. This study examined the association between over-indebtedness and pain and pain medication use. A cross-sectional study conducted among over-indebted individuals in 70 debt advisory centres in Germany (OID-survey; n = 699) was linked to the nationally representative German Health Interview and Examination Survey for Adults (DEGS1; n = 7987). Descriptive statistics and logistic regression analyses were used to examine the association between over-indebtedness and pain and pain medication use among participants with valid data on both outcome variables (n = 7560). Pain was experienced by over-indebted individuals more frequently (71.3%) compared to the general population (59.6%) whereas the prevalence of pain medication use was similar in both samples (DEGS1 12.6% vs. OID-survey 13.1%). Over-indebtedness significantly increased the odds of pain (aOR 1.30; 95%-CI 1.07-1.59) after adjusting for socioeconomic, demographic and health factors. The over-indebted were significantly less likely to use pain medication compared to the general population after adjustment (aOR 0.76; 95%-CI 0.58-0.99). Taking over-indebtedness into account as risk factor for pain and restricted pain medication use in research and clinical practice will help to advance the understanding of pain disparities, develop suitable interventions for preventive action and promote accessible pain management among those at risk.

A multicentre survey of pain management in cancer patients and physicians attending radiotherapy clinics in Shandong Province, China

Objective

To obtain a better understanding of the prevalence and management of pain in patients undergoing radiotherapy for cancer in Shandong Province, China.

Methods

This cross-sectional study used a questionnaire during face-to-face interviews to collect data from physicians and patients regarding the recognition, prevalence and treatment of pain during the waiting period before commencement of radiotherapy and during the radiotherapy period. Physicians and patients were recruited from 10 tertiary Class A hospitals across Shandong Province, China.

Results

A total of 184 patients and 87 physicians were recruited to the study. During the waiting period, pain was reported by the physicians according to their experience to affect 26.0% of patients, which almost agreed with the patients’ data (36.5%; 160 of 438). During the radiotherapy period, there was a significant difference in the reported prevalence of pain during the radiotherapy period between the physicians’ data (23.0%) based on their experience and the patients’ data (84.1%; 169 of 201 patients). The majority of physicians (98.9%; 86 of 87) agreed to the use opioids for pain management and 90.8% (79 of 87) were satisfied with the analgesic effect, but more than half of the patients who received pain treatment reported inadequate analgesia.

Conclusion

There was a high incidence of cancer pain, but insufficient assessment, inadequate treatment and inadequate education about pain in both the waiting and radiotherapy periods.
