Development and validation of a short-form Pain Medication Attitudes Questionnaire (PMAQ-14)

Pain medication beliefs in individuals with headache

OBJECTIVE

To evaluate pain medication beliefs in a community sample of individuals with headache.

BACKGROUND

Previous studies of medication adherence for individuals with headache have identified a high rate of prescription nonfulfillment, frequent medication discontinuation, and widely varying levels of medication-related satisfaction. Still, there is a limited understanding of how these individuals view their medications and their relationships with health-care providers. Insight into these perceptions could prove useful in explaining medication adherence behaviors.

METHODS

In this secondary analysis of a cross-sectional study, data from N = 215 adults with headache were analyzed. Participants completed the Pain Medication Attitudes Questionnaire (PMAQ), Center for Epidemiologic Studies Depression Scale (CES-D), State-Trait Anxiety Inventory Form Y-2, Weekly Stress Inventory Short Form, and Migraine Disability Scale. These participants also provided a list of their current pain medications.

RESULTS

Using the PMAQ, participants could be characterized as having medication beliefs that were "trusting and unconcerned" (n = 83/215 [38.6%]), "skeptical and somewhat worried" (n = 99/215 [46.0%]), or "skeptical and concerned" (n = 33/215 [15.3%]). Individuals with skeptical and concerned beliefs expressed elevated concerns (z > 1.15) about side effects, scrutiny, perceived need, tolerance, withdrawal, and addiction. Individuals who were trusting and unconcerned expressed low levels (z < -0.40) of these beliefs. Increasing levels of mistrust and medication concerns were correlated with higher depression scores on the CES-D, with values ranging from r = 0.23 to r = 0.38.

CONCLUSIONS

Subgroups of pain medication beliefs were identified, including two groups of patients with at least some concerns about their medical providers. Beliefs ranged from a lack of concern about using pain medications to worries about scrutiny and harm. It is unclear if poor experiences with pain medications cause these beliefs or if they prevent individuals from effectively utilizing medications. Additionally, more negative beliefs about pain medications were associated with more depressive symptoms.

PRESTO: Promoting Engagement for the Safe Tapering of Opioids

ABSTRACT

Twenty-four percent of all U.S. opioid overdose deaths involve a prescription opioid. Changing prescribing practices is considered a key step in reducing opioid overdoses. Primary care providers (PCPs) commonly lack the patient engagement skills needed to address patient resistance to taper or end opioid prescriptions. We developed and evaluated a protocol aimed at improving PCP opioid-prescribing patterns and modeled on the evidence-based Screening, Brief Intervention, and Referral to Treatment (SBIRT) approach. We conducted a time series trial comparing provider opioid prescribing 8 months before and 8 months after training with the PRomoting Engagement for Safe Tapering of Opioids (PRESTO) protocol. The 148 Ohio PCPs who completed PRESTO training gained confidence in their ability to engage their patients on the topics of opioid overdose risk and potential opioid tapering. Promoting Engagement for Safe Tapering of Opioids participants had decreased opioid-prescribing over time, but this was not significantly different from Ohio PCPs who had not received PRESTO training. Participants completing PRESTO training had small, but significant increased buprenorphine prescribing over time compared with Ohio PCPs who had not received PRESTO training. The PRESTO approach and opioid risk pyramid warrant further study and validation.

Effectiveness of a coordinated support system linking public hospitals to a health coaching service compared with usual care at discharge for patients with chronic low back pain: protocol for a randomised controlled trial

Background

Although many people with chronic low back pain (LBP) improve following conservative treatment, one in five will experience worsening symptoms after discharge from treatment and seek health care again. The current LBP clinical care pathway in many health services lacks a well-integrated, systematic approach to support patients to remain physically active and self-manage their symptoms following discharge from treatment. Health coaching can support people to improve physical activity levels and may potentially reduce health care utilisation for LBP. The primary aim of this study is to evaluate the effect of introducing a coordinated support system (linking hospital outpatient physiotherapy services to a public health coaching service) at discharge from LBP treatment, on the future use of hospital, medical, and health services for LBP, compared with usual care provided at discharge.

Methods

Three hundred and seventy-four adults with chronic non-specific LBP will be recruited from the outpatient physiotherapy departments of public hospitals in New South Wales, Australia. Participants will be individually randomised to a support system (n = 187) or usual care group (n = 187). All participants will receive usual care provided at discharge from treatment. Participants allocated to the support system will also receive up to 10 telephone-based health coaching sessions, delivered by the Get Healthy Service®, over a 6-month period. Health coaches will monitor and support participants to improve physical activity levels and achieve personal health-related goals. The primary outcome is the total number of encounters with hospital, medical, and health services for LBP, at 12 months from baseline. A within-trial economic evaluation will quantify the incremental costs and benefits of the support system from a health system perspective, to support reimbursement decision making.

Discussion

This study will establish the effect of a coordinated support system, introduced at discharge from treatment, on the future use of hospital, medical, and health services for LBP and various health outcomes.

Conclusion

Innovative community-driven solutions to support people with chronic LBP after discharge from treatment are urgently needed. Study findings will help inform health care policy and clinical practice in Australia.

Predictive variables of prescription opioid misuse in patients with chronic noncancer pain. Development of a risk detection scale: A registered report protocol

BACKGROUND

Opioid therapy is utilized for a broad range of chronic pain conditions. Several studies have highlighted the adverse effects of opioid medication due to the misuse of these drugs. The gradual increase in the use of opioids has become a global phenomenon and is generating social concern. Several treatment guidelines have strongly recommended assessing the risks and benefits of pharmacological treatment with opioids. These guidelines also recommend the psychological assessment of patients with chronic noncancer pain in order to make informed decisions on the advisability of intervention with opioids. Some authors have emphasized the relevance of assessing the risk of opioid misuse in patients with noncancer chronic pain before initiating treatment.

METHODS AND ANALYSIS

Two studies will be conducted, each with a different primary objective. The primary objective of the first study (Study 1) will be to conduct a comprehensive investigation to identify the factors most closely associated with subsequent opioid misuse; and based on the results of Study 1, the primary objective of the second study (Study 2) will be to develop a brief, reliable, valid, and useful instrument that would enable health care providers to make decisions on opioid prescription and on the required level of monitoring and follow-up. These decisions would have positive consequences for patient wellbeing. Study 1 will include a logistic regression analysis to test the hypothetical model. Study 2 will have a longitudinal design and include three assessment sessions in order to develop a measure to assess the risk of prescribed opioid misuse and to analyse its reliability and validity. Participants will be individuals with chronic noncancer pain attending three Pain Units. These individuals will either be undergoing pharmacological treatment that includes opioid analgesics (Study 1, N = 400) or are going to commence such treatment (Study 2, N = 250).

Manual therapy associated with topical heat reduces pain and self-medication in patients with tension-type headache

ABSTRACT Tension-type headache (TTH) is a significant public health problem. The myofascial trigger points in the masticatory and cervical muscles are related to pain located in the temporomandibular joint, face, and cranium according to specific patterns. Thus, therapeutic procedures should be directed to myofascial trigger points rather than to the area of referred pain. For this purpose, the massage therapy combined with the topical heat can provide effective results due to the increase of the local microcirculation, improving tissue perfusion and promoting muscle relaxation. In this study we investigated the effects of manual therapy associated with topical heat therapy in TTH pain. This is a single-arm study composed of 13 participants with TTH (females), which were submitted to a three-month research protocol. In the first month , they filled out a pain diary and then they were evaluated. In the following month, the treatment protocol was applied (8 sessions of 45 minutes, twice a week, involving massage for skin desensitization, myofascial trigger point deactivation and stretching (friction massage) on masticatory and trapezius muscles after the topical heat). Then, in the third month (follow-up period), the participants were instructed to fill out the pain diary once again. We observed a significant decrease in pain intensity in TTH episodes, and medication intake after treatment and it keeps decreasing in follow-up. We conclude that the combination of manual therapy protocol and topical heat reduced pain and episodes related to TTH, and self-medication use in our sample.

The Relation Between Patients' Beliefs About Pain Medication, Medication Adherence, and Treatment Outcome in Chronic Pain Patients: A Prospective Study

OBJECTIVES

Nonadherence to prescribed pain medication is common in chronic noncancer pain patients. Beliefs about pain medication have been reported to be associated with nonadherence behavior in cross-sectional studies. The aim of this study was to prospectively investigate the relationship between patients' beliefs about pain medication and their medication adherence and treatment outcome.

METHODS

Chronic noncancer pain patients completed a baseline questionnaire including the 47-item Pain Medication Attitudes Questionnaire, consisting of 7 subscales with regards to beliefs on prescribed medication. After 11 weeks, medication underuse and overuse were assessed by self-report. In addition, patient satisfaction with regards to the effect of prescribed pain medication and satisfaction as regards prescribed medication and care, and the burden of side effects were assessed.

RESULTS

A total of 133 participants completed the baseline questionnaire, and 99 patients completed the follow-up questionnaire. Concerns over side effects at baseline were positively associated with underuse and the presence of side effects after 11 weeks. The perceived need was positively associated with overuse, whereas concerns over addiction were negatively associated with overuse. Concerns over tolerance were negatively associated with patient satisfaction with medication effects after 11 weeks. Concerns over tolerance and mistrust in the prescribing doctor were negatively associated with satisfaction about medication and care.

CONCLUSION

Attitudes and concerns toward pain medication are associated with adherence patterns and outcome parameters. To improve medication adherence and therapy outcome, patient beliefs about pain medication should be taken into account by providing tailored education, adequate follow-up, or alternate therapy.

Establishing Credibility for Medical Marijuana: The Proposed Prometheus Dispensary Registry for Botanical Cannabis

A previous commentary in INNOVATIONS in Pharmacy argued that, given the lack of evidence for outcomes in medical marijuana, outside of a handful of randomized clinical trials and even fewer observational studies, good clinical practice points to the need for monitoring patients who received cannabis through certified medical marijuana dispensaries. The commentary noted the lack of standards for monitoring cannabis patients and the lack of feedback from the dispensary to providers. Botanical cannabis administration was occurring in, effectively, an evidence vacuum. More to the point, dispensary owners and investors seem uninterested in establishing a robust evidence base for cannabis outcomes. Given the range of conditions and symptoms presented by patients, to include the prevalence of multiple symptoms together with the range of potential cannabis formulations, dosing regimens and delivery options, a failure to monitor patients over the course of their exposure to cannabis in not acceptable. The purpose of this commentary is to report on a proposed on-line registry structure proposed by Prometheus Research for medical marijuana dispensaries in the US. The registry tracks and reports on patients over the course of treatment with botanical cannabis with the focus on severe or chronic non-cancer pain, severe nausea, persistent muscle spasms and seizures, together with prevalent comorbidities - fatigue, anxiety, depression and sleep. This is the first time a registry has been developed for dispensaries in the United States as a model for a robust evidence base to support botanical cannabis as a therapy option.

A Practice Based Chronic Pain Management Registry (CPMR): Structure and Content of Proposed Patient and Patient/Provider Platforms

Previous commentaries in the Formulary Evaluation section of INNOVATIONS in Pharmacy have pointed to the difficulties of establishing the credibility of trial-based and modeled claims for therapy interventions. Claims for interventions in the management of chronic pain are no exception. To meet this challenge, the Chronic Pain Management Registry (CPMR) has been designed to provide an evidence base for physician practices and health care decision makers to evaluate the impact of pain management interventions. The purpose of this commentary is to detail the development, structure and content of the CPMR in two versions: (i) a patient response version and (ii) a combined patient/provider response version. The CPMR has a potentially critical role to play in providing a framework for the effective auditing of practice compliance in the prescribing and monitoring of opioids in the management of chronic pain. The CPMR tracks, with on-line input from the patient and the treating physician, the process and outcomes of therapy interventions. These reports cover the overall pain experience of patients as well as pain intensity and functional status by eleven specific pain locations, covering both pharmacological and non-pharmacological interventions. Prior to each practice visit patients complete reports which are entered to the CPMR with a summary transmitted to the physician practice. Over time, these reports track the cumulative response to therapy as well as the perception of the patients as to whether or not the therapy has led to any substantive improvement in activity limitations, symptoms and quality of life. A particular focus of the CPMR is on monitoring and evaluating the experience with, and impact of opioid medications, to include the effectiveness of opioid formulations on reducing pain intensity and improving functional status, including an intensive assessment of the potential for and experience of opioid substance abuse for individual patients. The CPMR can also support monthly reports to the practice to summarize patient throughput, the response to care by target pain patients and profiles of opioid use and abuse. The CPMR can be customized to meet the needs of individual practices.

An international study of analgesic dependence among people with pain in the general population

BACKGROUND

Overuse of and dependence on analgesics (including opioids and other pain medications) are major international public health problems.

OBJECTIVE

To identify influences on analgesic dependence among analgesic users in the general populations of different countries.

METHODS

Online surveys of 1,283 people with pain in the UK, USA, Australia, Germany, Egypt and China/Macau/Hong Kong.

RESULTS

Levels of analgesic overuse and dependence were highest in Egypt and lowest in China/Macau/Hong Kong. In every country except Egypt, frequency of pain and frequency of analgesic use were correlated with analgesic dependence, and scores on the Need subscale of the Pain Medication Attitudes Questionnaire (PMAQ) independently predicted analgesic dependence. In the UK, USA, Australia, and Germany, frequency of analgesic use mediated the effects of pain frequency or intensity, and Need scores mediated the effects of frequency of analgesic use. In Egypt, more recent pain, analgesic overuse, and the Emotion and Solicitude subscales of the Survey of Pain Attitudes independently predicted analgesic dependence.

CONCLUSIONS

Across multiple countries, the impact of pain on analgesic dependence was mediated by frequency of analgesic use rather than overuse or abuse, and self-reported need for analgesics was the strongest independent predictor of dependence. Asking people directly about their feelings of needing analgesics could therefore identify those who could be helped to use analgesics less frequently, which should reduce their risk of dependence.
