The relationship between capacity and utilization of nonpharmacologic therapies in the US Military Health System

Background

Nonpharmacologic therapies (NPTs) are recommended as first-line treatments for pain, however the impact of expanding professional capacity to deliver these therapies on use has not been extensively studied. We sought to examine whether an effort by the US Military Health System (MHS) to improve access to NPTs by expanding professional capacity increased NPT utilization in a cohort at higher risk for pain – Army soldiers returning from deployment.

Methods

Our study involved secondary analysis of MHS workforce data derived from the Defense Medical Human Resources System Internet (DMHRSi), and healthcare utilization data obtained from two ambulatory record systems of the Military Health System (MHS) for a sample of 863,855 Army soldiers previously deployed to Iraq or Afghanistan over a 10-year period (2008–2017). We measured clinical provider capacity in three occupational groups responsible for pain management at 130 military treatment facilities (MTFs): physical therapy, chiropractic, and behavioral health, measured annually as full-time equivalence per 100,000 patients served at each MTF. Utilization in both direct and purchased care settings was measured as annual mean NPT users per 1000 sample members and mean encounters per NPT user. Generalized estimating equation models estimated the associations of facility-level occupational capacity measures and facility-level utilization NPT measures.

Results

In 2008, nearly all MTFs had some physical therapist and behavioral health provider capacity, but less than half had any chiropractor capacity. The largest increase in capacity from 2008 to 2017 was for chiropractors (89%) followed by behavioral health providers (77%) and physical therapists (37%). Models indicated that increased capacity of physical therapists and chiropractors were associated with significantly increased utilization of six out of seven NPTs. Acupuncture initiation was associated with capacity increases in each occupation. Increased professional capacity in MTFs was associated with limited but positive effects on NPT utilization in purchased care.

Conclusions

Increasing occupational capacity in three professions responsible for delivering NPTs at MTFs were associated with growing utilization of seven NPTs in this Army sample. Despite increasing capacity in MTFs, some positive associations between MTF capacity and purchased care utilization suggest an unmet need for NPTs. Future research should examine if these changes lead to greater receipt of guideline-concordant pain management.

Does TENS Reduce the Intensity of Acute and Chronic Pain? A Comprehensive Appraisal of the Characteristics and Outcomes of 169 Reviews and 49 Meta-Analyses

Background and Objectives: Uncertainty about the clinical efficacy of transcutaneous electric nerve stimulation (TENS) to alleviate pain spans half a century. There has been no attempt to synthesise the entire body of systematic review evidence. The aim of this comprehensive review was to critically appraise the characteristics and outcomes of systematic reviews evaluating the clinical efficacy of TENS for any type of acute and chronic pain in adults. Materials and Methods: We searched electronic databases for full reports of systematic reviews of studies, overviews of systematic reviews, and hybrid reviews that evaluated the efficacy of TENS for any type of clinical pain in adults. We screened reports against eligibility criteria and extracted data related to the characteristics and outcomes of the review, including effect size estimates. We conducted a descriptive analysis of extracted data. Results: We included 169 reviews consisting of eight overviews, seven hybrid reviews and 154 systematic reviews with 49 meta-analyses. A tally of authors' conclusions found a tendency toward benefits from TENS in 69/169 reviews, no benefits in 13/169 reviews, and inconclusive evidence in 87/169 reviews. Only three meta-analyses pooled sufficient data to have confidence in the effect size estimate (i.e., pooled analysis of >500 events). Lower pain intensity was found during TENS compared with control for chronic musculoskeletal pain and labour pain, and lower analgesic consumption was found post-surgery during TENS. The appraisal revealed repeated shortcomings in RCTs that have hindered confident judgements about efficacy, resulting in stagnation of evidence. Conclusions: Our appraisal reveals examples of meta-analyses with 'sufficient data' demonstrating benefit. There were no examples of meta-analyses with 'sufficient data' demonstrating no benefit. Therefore, we recommend that TENS should be considered as a treatment option. The considerable quantity of reviews with 'insufficient data' and meaningless findings have clouded the issue of efficacy. We offer solutions to these issues going forward.

The brain and behavioral correlates of motor-related analgesia (MRA)

The human motor system has the capacity to act as an internal form of analgesia. Since the discovery of the potential influence of motor systems on analgesia in rodent models, clinical applications of targeting the motor system for analgesia have been implemented. However, a neurobiological basis for motor activation's effects on analgesia is not well defined. Motor-related analgesia (MRA) is a phenomenon wherein a decrease in pain symptoms can be achieved through either indirect or direct activation of the motor axis. To date, research has focused on (a) evaluating the pain-motor interaction as one focused on the acute protection from painful stimuli; (b) motor cortex stimulation for chronic pain; or (c) exercise as a method of improving chronic pain in animal and human models. This review evaluates (1) current knowledge surrounding how pain interferes with canonical neurological performance throughout the motor axis; and (2) the physiological basis for motor-related analgesia as a means to reduce pain symptom loads for patients. A proposal for future research directions is provided.

Characteristics of stakeholder involvement in systematic and rapid reviews: a methodological review in the area of health services research

OBJECTIVE

Engaging stakeholders in reviews is considered to generate more relevant evidence and to facilitate dissemination and use. As little is known about stakeholder involvement, we assessed the characteristics of their engagement in systematic and rapid reviews and the methodological quality of included studies. Stakeholders were people with a particular interest in the research topic.

DESIGN

Methodological review.

SEARCH STRATEGY

Four databases (Medline, Embase, Cochrane database of systematic reviews, databases of the University of York, Center for Reviews and Dissemination (CRD)) were searched based on an a priori protocol. Four types of reviews (Cochrane and non-Cochrane systematic reviews, rapid and CRD rapid reviews) were retrieved between January 2011 and October 2015, pooled by potential review type and duplicates excluded. Articles were randomly ordered and screened for inclusion and exclusion criteria until 30 reviews per group were reached. Their methodological quality was assessed using AMSTAR and stakeholder characteristics were collected.

RESULTS

In total, 57 822 deduplicated citations were detected with potential non-Cochrane systematic reviews being the biggest group (56 986 records). We found stakeholder involvement in 13% (4/30) of Cochrane, 20% (6/30) of non-Cochrane, 43% (13/30) of rapid and 93% (28/30) of CRD reviews. Overall, 33% (17/51) of the responding contact authors mentioned positive effects of stakeholder involvement. A conflict of interest statement remained unmentioned in 40% (12/30) of non-Cochrane and in 27% (8/30) of rapid reviews, but not in Cochrane or CRD reviews. At most, half of non-Cochrane and rapid reviews mentioned an a priori study protocol in contrast to all Cochrane reviews.

CONCLUSION

Stakeholder engagement was not general practice, except for CRD reviews, although it was more common in rapid reviews. Reporting factors, such as including an a priori study protocol and a conflict of interest statement should be considered in conjunction with involving stakeholders.

Can Direct Current Electrotherapy Be Used for Patients With Orthopedic Implants?

Introduction:

Although electrotherapy appears to have particularly interesting applications in the field of postoperative orthopedic rehabilitation, relatively little scientifically based research has been conducted in the area of electrotherapy with regard to safety involving patients with orthopedic implants.

Method:

Three electrotherapy forms were tested, such as high-volt stimulation (HVS), transcutaneous electric nerve stimulation (TENS), and galvanic current (GAL), using a model system containing a metal implant plate to evaluate whether heating in excess of 3°C would occur.

Results:

All changes in temperature for HVS, GAL, and TENS therapeutic electrical currents observed in our model system fall below the predefined 3°C.

Conclusion:

To the best of our knowledge, this is the first experimental based observation that prolonged exposure to a direct electrical current at therapeutic strength does not result in heating of metal titanium plates.

Quality of conduct and reporting in rapid reviews: an exploration of compliance with PRISMA and AMSTAR guidelines

BACKGROUND

Rapid reviews are an accelerated evidence synthesis approach intended to meet the timely needs of decision-makers in healthcare settings. Quality of conduct and reporting has been described in the rapid review literature; however, no formal assessment has been carried out using available instruments. The objective of this study was to explore compliance with conduct and reporting guidelines in rapid reviews published or posted online during 2013 and 2014.

METHODS

We performed a comprehensive literature search for rapid reviews using multiple bibliographic databases (e.g. PubMed, MEDLINE, EMBASE, the Cochrane Library) through December 31, 2014. Grey literature was searched thoroughly, and health technology assessment agencies were surveyed to identify additional rapid review products. Candidate reviews were assessed for inclusion using pre-specified eligibility criteria. Detailed data was collected from the included reviews on study and reporting characteristics and variables significant to rapid reviews (e.g. nomenclature, definition). We evaluated the quality of conduct and reporting of included rapid reviews using the A Measurement Tool to Assess Systematic Reviews (AMSTAR) and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklists. Compliance with each checklist item was examined, and the sum of adequately reported items was used to describe overall compliance. Rapid reviews were stratified to explore differences in compliance related to publication status. The association between compliance and time to completion or length of publication was explored through univariate regression.

RESULTS

Sixty-six rapid reviews were included. There were heterogeneous nomenclature, research questions and approaches to rapid reviews. Compliance with AMSTAR and PRISMA checklists was poor. Published rapid reviews were compliant with individual PRISMA items more often than unpublished reviews, but no difference was seen in AMSTAR item compliance overall. There was evidence of an association between length of publication and time to completion and the number of adequately reported PRISMA or AMSTAR items.

CONCLUSIONS

Transparency and inadequate reporting are significant limitations of rapid reviews. Scientific editors, authors and producing agencies should ensure that the reporting of conduct and findings is accurate and complete. Further research may be warranted to explore reporting and conduct guidelines specific to rapid reviews and how these guidelines may be applied across the spectrum of rapid review approaches.

Perceptions of other integrative health therapies by Veterans with pain who are receiving massage

Veterans are increasingly using complementary and integrative health (CIH) therapies to manage chronic pain and other troubling symptoms that significantly impair health and quality of life. The Department of Veterans Affairs (VA) is exploring ways to meet the demand for access to CIH, but little is known about Veterans' perceptions of the VA's efforts. To address this knowledge gap, we conducted interviews of 15 inpatients, 8 receiving palliative care, and 15 outpatients receiving CIH in the VA. Pain was the precipitating factor in all participants' experience. Participants were asked about their experience in the VA and their opinions about which therapies would most benefit other Veterans. Participants reported that massage was well-received and resulted in decreased pain, increased mobility, and decreased opioid use. Major challenges were the high ratio of patients to CIH providers, the difficulty in receiving CIH from fee-based CIH providers outside of the VA, cost issues, and the role of administrative decisions in the uneven deployment of CIH across the VA. If the VA is to meet its goal of offering personalized, proactive, patient-centered care nationwide then it must receive support from Congress while considering Veterans' goals and concerns to ensure that the expanded provision of CIH improves outcomes.

Effectiveness of active self-care complementary and integrative medicine therapies: options for the management of chronic pain symptoms

OBJECTIVES

Chronic pain management typically consists of prescription medications or provider-based, behavioral, or interventional procedures that are often ineffective, may be costly, and can be associated with undesirable side effects. Because chronic pain affects the whole person (body, mind, and spirit), patient-centered complementary and integrative medicine (CIM) therapies that acknowledge the patients' roles in their own healing processes have the potential to provide more efficient and comprehensive chronic pain management. Active self-care CIM (ACT-CIM) therapies allow for a more diverse, patient-centered treatment of complex symptoms, promote self-management, and are relatively safe and cost-effective. To date, there are no systematic reviews examining the full range of ACT-CIM used for chronic pain symptom management.

METHODS

A systematic review was conducted, using Samueli Institute's Rapid Evidence Assessment of the Literature methodology, to rigorously assess both the quality of the research on ACT-CIM modalities and the evidence for their efficacy and effectiveness in treating chronic pain symptoms. A working group of subject matter experts was also convened to evaluate the overall literature pool and develop recommendations for the use and implementation of these modalities.

RESULTS

Following key database searches, 146 randomized controlled trials were included in the review, 18 of which directly compared ACT-CIM approaches with one another.

CONCLUSIONS

This article summarizes the current evidence, quality, effectiveness, and safety of these modalities. Recommendations and next steps to move this field of research forward are also discussed. The entire scope of the review is detailed throughout the current Pain Medicine supplement.

An analysis of the various chronic pain conditions captured in a systematic review of active self-care complementary and integrative medicine therapies for the management of chronic pain symptoms

OBJECTIVES

Chronic pain management typically consists of prescription medications or provider-based, behavioral, or interventional procedures that are often ineffective, may be costly, and can be associated with undesirable side effects. Because chronic pain affects the whole person (body, mind, and spirit), patient-centered complementary and integrative medicine (CIM) therapies that acknowledge the patients' roles in their own healing processes have the potential to provide more efficient and comprehensive chronic pain management.

To date, there are no systematic reviews examining the full range of ACT-CIM used for chronic pain symptom management.

METHODS

A systematic review was conducted, using Samueli Institute's rapid evidence assessment of the literature (REAL©) methodology, to rigorously assess both the quality of the research on ACT-CIM modalities and the evidence for their efficacy and effectiveness in treating chronic pain symptoms. A working group of subject matter experts was also convened to evaluate the overall literature pool and develop recommendations for the use and implementation of these modalities.

RESULTS

Following key database searches, 146 randomized controlled trials, covering 33 different pain conditions, were included in the review.

CONCLUSIONS

This article categorized studies by pain condition, describing the diagnostic criteria used and modalities that seem most effective for each condition. Complexities associated with investigating chronic pain populations are also discussed. The entire scope of the review, categorized by modality rather than pain condition, is detailed throughout the current Pain Medicine supplement.
