Acupuncture provides short-term pain relief for patients in a total joint replacement program

Nanotechnology for Pain Management

Introduction: In the context of the current opioid crisis, non-pharmacologic approaches to pain management have been considered important alternatives to the use of opioids or analgesics. Advancements in nano and quantum technology have led to the development of several nanotransporters, including nanoparticles, micelles, quantum dots, liposomes, nanofibers, and nano-scaffolds. These modes of nanotransporters have led to the development of new drug formulations. In pain medicine, new liposome formulations led to the development of DepoFoam™ introduced by Pacira Pharmaceutical, Inc. (Parsippany, NJ, USA). This formulation is the base of DepoDur™, which comprises a combination of liposomes and extended-release morphine, and Exparel™, which comprises a combination of liposomes and extended-release bupivacaine. In 2021, Heron Therapeutics (San Diego, CA, USA) created Zynrelef™, a mixture of bupivacaine and meloxicam. Advancements in nanotechnology have led to the development of devices/patches containing millions of nanocapacitors. Data suggest that these nanotechnology-based devices/patches reduce acute and chronic pain. Methods: Google and PubMed searches were conducted to identify studies, case reports, and reviews of medical nanotechnology applications with a special focus on acute and chronic pain. This search was based on the use of keywords like nanotechnology, nano and quantum technology, nanoparticles, micelles, quantum dots, liposomes, nanofibers, nano-scaffolds, acute and chronic pain, and analgesics. This review focuses on the role of nanotechnology in acute and chronic pain. Results: (1) Nanotechnology-based transporters. DepoDur™, administered epidurally in 15, 20, or 25 mg single doses, has been demonstrated to produce significant analgesia lasting up to 48 h. Exparel™ is infiltrated at the surgical site at the recommended dose of 106 mg for bunionectomy, 266 mg for hemorrhoidectomy, 133 mg for shoulder surgery, and 266 mg for total knee arthroplasty (TKA). Exparel™ is also approved for peripheral nerve blocks, including interscalene, sciatic at the popliteal fossa, and adductor canal blocks. The injection of Exparel™ is usually preceded by an injection of plain bupivacaine to initiate analgesia before bupivacaine is released in enough quantity from the depofoarm to be pharmacodynamically effective. Finally, Zynrelef™ is applied at the surgical site during closure. It was initially approved for open inguinal hernia, abdominal surgery requiring a small-to-medium incision, foot surgery, and TKA. (2) Nanotechnology-based devices/patches. Two studies support the use of nanocapacitor-based devices/patches for the management of acute and chronic pain. A randomized study conducted on patients undergoing unilateral primary total knee (TKA) and total hip arthroplasty (THA) provided insight into the potential value of nanocapacitor-based technology for the control of postoperative acute pain. The results were based on 2 studies, one observational and one randomized. The observational study was conducted in 128 patients experiencing chronic pain for at least one year. This study suggested that compared to baseline, the application of a nanocapacitor-based Kailo™ pain relief patch on the pain site for 30 days led to a time-dependent decrease in pain and analgesic use and an increase in well-being. The randomized study compared the effects of standard of care treatment to those of the same standard of care approach plus the use of two nanocapacitor-based device/patches (NeuroCuple™ device) placed in the recovery room and kept in place for three days. The study demonstrated that the use of the two NeuroCuple™ devices was associated with a 41% reduction in pain at rest and a 52% decrease in the number of opioid refills requested by patients over the first 30 days after discharge from the hospital. Discussion: For the management of pain, the use of nano-based technology has led to the development of nano transporters, especially focus on the use of liposome and nanocapacitors. The use of liposome led to the development of DepoDur™, bupivacaine Exparel™ and a mixture of bupivacaine and meloxicam (Zynrelef™) and more recently lidocaine liposome formulation. In these cases, the technology is used to prolong the duration of action of drugs included in the preparation. Another indication of nanotechnology is the development of nanocapacitor device or patches. Although, data obtained with the use of nanocapacitors are still limited, evidence suggests that the use of nanocapacitors devices/patches may be interesting for the treatment of both acute and chronic pain, since the studies conducted with the NeuroCuple™ device and the based Kailo™ pain relief patch were not placebo-controlled, it is clear that additional placebo studies are required to confirm these preliminary results. Therefore, the development of a placebo devices/patches is necessary. Conclusions: Increasing evidence supports the concept that nanotechnology may represent a valuable tool as a drug transporter including liposomes and as a nanocapacitor-based device/patch to reduce or even eliminate the use of opioids in surgical patients. However, more studies are required to confirm this concept, especially with the use of nanotechnology incorporated in devices/patches.

Immediate Effects of Integrative Health and Medicine Modalities Among Outpatients With Moderate-To-Severe Symptoms

Background

Patients seeking integrative health and medicine (IHM) modalities often present with multiple physical and psychological concerns. Research supports IHM's effectiveness for addressing symptoms over longer time periods. However, few studies have evaluated immediate outpatient effects.

Objective

This study describes pre-encounter patient-reported outcome (PRO) clusters and examines the immediate clinical effectiveness of IHM modalities on pain, stress, and anxiety among outpatients with moderate-to-severe symptoms.

Methods

A retrospective review was conducted of encounters among adults presenting to outpatient acupuncture, chiropractic, massage, integrative medicine consultation, or osteopathic manipulation treatment between January 2019 and July 2020. Encounters were included if patients reported pre-encounter pain, stress, or anxiety ≥4 on a numeric rating scale (NRS). Outcome analyses included random effects for patient and provider using a mixed model.

Results

Across 7335 clinical encounters among 2530 unique patients (mean age: 49.14 years; 81.0% female; 75.9% White; 15.8% Black/African American), the most common pre-encounter PRO clusters were pain, stress, and anxiety ≥4 (32.4%); pain ≥4 only (31.3%); and stress and anxiety ≥4 (15.6%). Clinically meaningful single-encounter mean [95% CI] changes were observed across all modalities in pain (-2.50 [-2.83, -2.17]), stress (-3.22 [-3.62, -2.82]), and anxiety (-3.05 [-3.37, -2.73]).

Conclusion

Patients presenting to outpatient IHM with moderate-to-severe symptoms most often presented with pain, stress, and anxiety ≥4 on the NRS. Multiple IHM modalities yielded clinically meaningful (≥2 unit) immediate reductions in these symptoms. Future research measuring immediate and longitudinal effectiveness is needed to optimize the triage and coordination of IHM modalities to meet patients' needs.

Effects of contralateral versus ipsilateral electroacupuncture for analgesia and rehabilitation after unilateral total knee arthroplasty: a randomized controlled trial

PURPOSE

Total knee arthroplasty (TKA) is a treatment for advanced knee osteoarthritis. Since postoperative pain affects rehabilitation, this study aimed to determine whether electroacupuncture (EA) contralateral to the surgical site is more effective than ipsilateral EA or sham EA in terms of relieving postoperative pain and promoting post-TKA rehabilitation.

METHODS

In this parallel, single-blind randomized controlled trial, 114 patients undergoing unilateral TKA were assigned to the contralateral EA (EA on the contralateral side + sham EA on the ipsilateral), ipsilateral EA (EA on the ipsilateral + sham EA on the contralateral side), or sham EA (sham EA on both sides) groups (n = 38 each). Treatment was performed once daily on postoperative days 1-3. The visual analog scale (VAS) scores, additional opioid doses via patient-controlled analgesia (PCA) pump, Hospital for Special Surgery (HSS) knee scores, active/passive range of motion (AROM/PROM), swelling around the knee joint, and Hamilton anxiety scale (HAMA) scores were used for postoperative evaluation.

RESULTS

At 3 days postoperatively, the VAS scores, HSS scores, AROM/PROM, swelling around the knee, and HAMA scores in the contralateral EA and ipsilateral EA groups were significantly improved compared with baseline. In addition, VAS scores, HSS scores, PROM and swelling around the knee were significantly better in the contralateral and ipsilateral EA groups than in the sham EA group, but similar in the two true EA groups. Furthermore, PCA additional dose release was significantly higher in the sham EA group than in the two true EA groups (which did not significantly differ). At 10 days postoperatively, the HSS scores, AROM/PROM, and HAMA scores were better in the contralateral and ipsilateral EA groups than in the sham EA group, but similar in the two true EA groups.

CONCLUSION

Contralateral EA is more effective than sham EA for treating postoperative pain following TKA, but has an analgesic effect similar to that of ipsilateral EA.

Acupuncture Effect on Analgesic Consumption and Cortisol Levels Following Total Knee Arthroplasty: A Randomized Controlled Trial

Objective

Pain following total knee arthroplasty (TKA) is common. Various modalities of treating orthopedic postoperative pain (POP) exist; however, the optimal management of POP remains unclear. The purpose of this study was to examine acupuncture's effect on postoperative analgesic consumption and cortisol levels in patients undergoing TKA.

Materials and Methods

In this randomized controlled trial, 80 patients scheduled for elective TKA surgery were recruited and randomly assigned to 2 groups: (1) an intervention group, receiving acupuncture treatment on days 1 and 2 in addition to standard POP management (n = 40) and a control group, who received standard POP management only (n = 40).

Results

There was no statistical difference between the groups in analgesic consumption on days 1 and 3 postoperatively. On day 5 postoperatively, lower analgesic consumption was seen in the intervention group, compared to the control group. However, this difference was not statistically significant (1.4 versus 2.3, respectively; P = 0.215). There was no statistical difference between the groups in cortisol levels on day 1 postoperatively. In contrast, on day 2 postoperatively, cortisol level was significantly lower in the intervention group, compared to the control group (296 nmol/L versus 400 nmol/L, respectively; P < 0.05).

Conclusions

The findings suggest that acupuncture may have some effect on patients' analgesic consumption short-term after TKA. Further studies with larger samples are required for establishing these results.This trial was registered at ClinicalTrials.gov (Registration #: NCT03415204).

Use of Nanotechnology as an Alternative to Opioids for Post-operative Pain Management Following TKA

Introduction

In response to the current opioid crisis, there is a great interest to develop non-pharmacologic approaches to post-operative pain management for patients undergoing total knee arthroplasty (TKA).

Case Report

We report a case of a patient whose post-operative pain following TKA was managed using the newly designed NeuroCuple™ device, a patch based on the use of nanotechnology. The NeuroCuple™ device was placed above the knee by the patient at home. The use of the NeuroCuple™ device allowed the patient completely avoid the use of any opioids at home.

Conclusion

Our report suggests that the use of the NeuroCuple™ device may represent an interesting alternative to opioids for the peri-operative management of pain following a primary, unilateral TKA.

Effectiveness of music therapy within community hospitals: an EMMPIRE retrospective study

Introduction

Given the challenges health systems face in providing effective nonpharmacologic treatment for pain and psychological distress, clinical effectiveness studies of evidence-based strategies such as music therapy (MT) are needed.

Objectives

This study examined changes in patient-reported outcomes (PROs) after MT and explored variables associated with pain reduction of ≥2 units on a 0 to 10 numeric rating scale (NRS).

Methods

A retrospective review was conducted on initial MT interventions provided to adults receiving community hospital care between January 2017 and July 2020. Sessions were included if participants reported pre-session pain, anxiety, and/or stress scores of ≥4 on the NRS. Data analysis included a bootstrap analysis of single-session changes in PROs and a logistic regression exploring variables associated with pain reduction (ie, ≥2 units vs <2 units).

Results

Patients (n = 1056; mean age: 63.83 years; 76.1% female; 57.1% White; 41.1% Black/African American) reported clinically significant mean reductions in pain (2.04 units), anxiety (2.80 units), and stress (3.48 units). After adjusting for demographic, clinical, and operational characteristics in the model (c-statistic = 0.668), patients receiving an MT session in which pain management was a goal were 4.32 times more likely (95% confidence interval 2.26, 8.66) to report pain reduction of ≥2 units than patients receiving an MT session in which pain management was not a session goal.

Conclusion

This retrospective study supports the clinical effectiveness of MT for symptom management in community hospitals. However, additional research is needed to determine which characteristics of MT interventions and patients influence pain change.

Effect of Acupuncture on Postoperative Pain in Patients after Laparoscopic Cholecystectomy: A Randomized Clinical Trial

Objective

To evaluate the efficacy and safety of acupuncture compared to that of parecoxib sodium on postoperative pain (POP), postoperative nausea and vomiting (PONV), and the Bruggemann Comfort Scale (BCS) in patients following laparoscopic cholecystectomy (LC).

Methods

Eligible patients admitted to the hospital for LC were randomly allocated to either acupuncture or control groups in a 1 : 1 ratio. The subjects in the acupuncture group received acupuncture while those in the control group were injected by parecoxib sodium at their requests. The pain score, PONV score, and BCS were assessed at 0 h, 6 h, 9 h, and 12 h after operation. The primary outcome was the pain score. The secondary outcomes included the number of patients asking for parecoxib sodium from the two groups at 0-6 h and 6-12 h, PONV score, and BCS score.

Results

The pain score of the acupuncture group were lower in acupuncture than that in the control group at 6 h and 9 h after operation (P=0.002, P=0.008). However, no difference was found at 12 h. Besides, the number of patients administered parecoxib sodium in acupuncture group was less than that in the control group both at 0-6 h and 6-12 h after operation (P=0.019, P < 0.001). Similarly, there were significantly lower levels of PONV score and higher levels of BCS at 6 h after operation in the acupuncture group than in the control group. However, no difference was found at 9 h and 12 h.

Conclusion

Acupuncture can clinically improve the short-term treatment of postoperative pain after LC and reduce the request for extra analgesics; therefore, acupuncture might be a potential method as one of multimodal analgesia techniques to treat POP following LC.

Non-pharmaceutical treatments to relieve pain or reduce opioid analgesic intake and improve quality of life after total hip replacement: a meta analysis

To reduce pain after total hip replacement (THR), researchers are interested in drug-free interventions. However, there is still a lack of consensus on their prevention efficacy. We performed a meta-analysis to evaluate the use of nonpharmaceutical interventions for postoperative pain management after THR. We searched the Cochrane Library, MEDLINE, EMBASE, Web of Science, PEDRO, and ClinicalTrials.gov databases for articles published between and 1991 and 2020. The main outcome measures were postoperative pain, opioid consumption, and quality of life (QoL). In total, 1,942 patients were studied. We found moderate evidence indicating postoperative pain relief measured by the Western Ontario and McMaster Universities Arthritis Index Scale, with mean differences (MDs) of -0.28 (95% confidence interval [CI], -0.49 to -0.07; P=0.01; I² =0%) within three months, -0.19 (95% CI, -0.40 to 0.02; P=0.07; I² =0%) between 3-6 months, and -0.13 (95% CI, -0.35 to 0.08; P=0.21; I² =0%) between 6-12 months. Additionally, we found that acupuncture therapy could reduce opioid analgesic consumption (MD, -0.98; 95% CI, -1.18 to -0.79; fentanyl [mg/h]; P<0.01; I² =72.2%) and significantly improve pain relief with an MD of 0.90 (95% CI, 0.47 to 1.33; P<0.01; I² =0%) measured using the visual analog scale. Electrotherapy slightly improved perceived pain with an MD of 0.22 (95% CI, -0.27 to 0.70; P=0.37; I² =0%). Moreover, moderate evidence has shown that preoperative exercises improve QoL. This meta-analysis suggested that continuous passive motion did not improve pain or QoL. Postoperative exercise was associated with pain relief and improved QoL. Acupuncture therapy after THR has been shown to reduce opioid analgesic consumption.

Acupuncture therapy as an Evidence-Based Nonpharmacologic Strategy for Comprehensive Acute Pain Care: the Academic Consortium Pain Task Force White Paper Update

Background

A crisis in pain management persists, as does the epidemic of opioid overdose deaths, addiction, and diversion. Pain medicine is meeting these challenges by returning to its origins: the Bonica model of multidisciplinary pain care. The 2018 Academic Consortium White Paper detailed the historical context and magnitude of the pain crisis and the evidence base for nonpharmacologic strategies. More than 50% of chronic opioid use begins in the acute pain care setting. Acupuncture may be able to reduce this risk.

Objective

This article updates the evidence base for acupuncture therapy for acute pain with a review of systematic reviews and meta-analyses on postsurgical/perioperative pain with opioid sparing and acute nonsurgical/trauma pain, including acute pain in the emergency department.

Methods

To update reviews cited in the 2018 White Paper, electronic searches were conducted in PubMed, MEDLINE, CINAHL, and the Cochrane Central Register of Controlled Trials for “acupuncture” and “acupuncture therapy” and “acute pain,” “surgery,” “peri-operative,” “trauma,” “emergency department,” “urgent care,” “review(s) ,” “systematic review,” “meta-analysis,” with additional manual review of titles, links, and reference lists.

Results

There are 22 systematic reviews, 17 with meta-analyses of acupuncture in acute pain settings, and a review for acute pain in the intensive care unit. There are additional studies of acupuncture in acute pain settings.

Conclusion

The majority of reviews found acupuncture therapy to be an efficacious strategy for acute pain, with potential to avoid or reduce opioid reliance. Future multicenter trials are needed to clarify the dosage and generalizability of acupuncture for acute pain in the emergency department. With an extremely low risk profile, acupuncture therapy is an important strategy in comprehensive acute pain care.

Effect of Inpatient Integrative Medicine Consultation on 30-Day Readmission Rates: A Retrospective Observational Study at a Major U.S. Academic Hospital

Objectives: The prevalence of inpatient integrative medicine (IM) consult services is increasing among academic health care institutions. The diversity of services between institutions, as well as the novel nature of such interventions, makes it challenging for health care administrators to determine the cost/benefit of adding such a program to their institution. The main purpose of this study was to examine the performance of the new University of California, Los Angeles (UCLA) East-West (EW) consult service as measured by 30-day readmission rates and lengths of stay. Design: This is a retrospective observational case-control study with participants matched to themselves. Setting: UCLA Santa Monica Hospital, a 281-bed academic tertiary care hospital near Los Angeles, California. Subjects: Patients who had received an EW consultation during the inaugural 20 months of the program (2018-2020), and who had been hospitalized in the prior 2 years from the date of their first EW consult. Intervention: Inpatient East-West consultation, which may include counseling, acupuncture and/or trigger point injections depending on medical necessity. Outcome Measures: Thirty-day readmission rates and lengths of hospital admission were compared between the hospitalization that included an EW consult (which included the use of acupuncture and/or trigger point injections when appropriate) and any prior admissions during the 2 years before that EW consult. Secondary outcomes included quantitative analysis of average number of treatments and qualitative assessment of integrative treatment(s) received, conditions treated, and reasons that EW treatment may have been deferred during a consult. Results: One hundred sixty-five unique patients met the study criteria. The EW consultation was associated with clinically relevant, statistically significant decreased 30-day readmission rates (33.0% vs. 4.6%, p < 0.001, odds ratio [OR] 0.10, 95% confidence interval [CI] 0.06-0.17). This effect was similar when limiting the analysis to pain-related admissions (32.3% vs. 3.4%, p < 0.001, OR = 0.07, 95% CI 0.03-0.16). Hospital admissions with EW consults were found to have a statistically significant increased length of stay (7.03 days vs. 5.40 days, p < 0.001). Conclusion: The EW medicine, an example of IM, correlates with a reduced risk of 30-day readmission and with modestly increased lengths of stay.

Traditional Chinese Medicine for Postoperative Care following Anterior Cruciate Ligament Reconstruction: A Systematic Review and Meta-Analysis

Objectives

This review verifies the clinical effects of traditional Chinese medicine (TCM) combined with conventional rehabilitation after anterior cruciate ligament reconstruction (ACLR).

Methods

MEDLINE/PubMed, EMBASE, CENTRAL, JMAS, CNKI, and seven Korean databases were searched using predetermined strategies. The risk of bias was assessed using Cochrane Collaboration's tool and a meta-analysis was conducted accordingly.

Results

Nineteen randomized controlled trials involving 1283 participants were included in this systematic review and meta-analysis. The TCM treatment group showed more significant improvements in pain (MD −0.74, 95% CI [−0.93, −0.54]; I2 = 89%), range of motion (ROM) (SMD 1.19, 95% CI [0.78, 1.59]; I2 = 78%), and knee swelling (SMD −1.72, 95% CI [−2.38, −1.07]; I2 = 76%). The Lysholm score of the TCM treatment group significantly improved (MD 5.62, 95% CI [3.93, 7.32]; I2 = 84%) relative to the control group. The IKDC subjective score (MD 3.40, 95% CI [−0.61, 7.41]; I2 = 97%) and the hospital for special surgery (HSS) score did not improve initially (MD 6.79, 95% CI [−1.27, 14.86]; I2 = 97%) but did so during the subgroup analysis. TCM showed a long-term effect on the IKDC subjective score (MD −0.51, 95% CI [−1.69, 0.67]; I2 = 30%). A longer treatment period of 12 weeks showed more improvement (MD 5.96, 95% CI [0.69, 11.22]; I2 95%).

Conclusion

TCM can be used as an adjuvant therapy to conventional rehabilitation for relieving pain, improving ROM and oedema, and facilitating better function of the knee joint after ACLR. However, this recommendation should be cautiously applied in clinical practice owing to the low quality of the included studies.

Effects of Acupuncture on Postoperative Pain After Total Knee Replacement: Systematic Literature Review and Meta-Analysis

OBJECTIVE

To identify the analgesic effectiveness of acupuncture after total knee replacement by systematic review.

METHODS

A search of randomized controlled trials was conducted in five English medical electronic databases and five Chinese databases. Two reviewers independently searched in five English medical electronic databases and five Chinese databases. Two reviewers independently retrieved related studies, assessed the methodological quality, and extracted data with a standardized data form. Meta-analyses were performed with all-time-points meta-analysis.

RESULTS

A total of seven studies with 891 participants were included. The meta-analysis results indicated that acupuncture had a statistically significant influence on pain relief (standardized mean difference = -0.705, 95% CI -1.027 to -0.382, P = 0.000). The subgroup analysis results showed that acupuncture's effects on analgesia had a statistically significant influence (standardized mean difference= -0.567, 95% CI -0.865 to -0.269, P = 0.000). The main acupuncture points that produced an analgesic effect when they were used after total knee replacement included the Xuehai, Liangqiu, Dubi, Neixiyan, Yanglingquan, and Zusanli points. Electroacupuncture frequency ranged between 2 and 100 Hz.

CONCLUSIONS

As an adjunct modality, the use of acupuncture is associated with reduced pain and use of analgesic medications in postoperative patients. In particular, ear acupuncture 1 day before surgery could reduce analgesia .

The expanding role of chronic pain interventions in multimodal perioperative pain management: a narrative review

Surgery is a risk factor for chronic pain and long-term opioid use. As perioperative pain management continues to evolve, treatment modalities traditionally used for chronic pain therapy may provide additional benefit to patients undergoing surgery. Interventions such as radiofrequency ablation, cryoneurolysis, and neuromodulation may potentially be used in conjunction with acute pain procedures such as nerve blocks and multimodal analgesia. Pharmacological agents associated with chronic pain medicine, including gabapentinoids, ketamine, and selective serotonin reuptake inhibitors, may be useful adjuncts in perioperative pain management when indicated. There may also be a role for acupuncture, music therapy, and other integrative medicine therapies. A transitional pain service can help coordinate outpatient care with inpatient perioperative pain management and promote a more personalized and comprehensive approach that can improve postoperative outcomes.

Significant Pain Reduction in Hospitalized Patients Receiving Integrative Medicine Interventions by Clinical Population and Accounting for Pain Medication

Background: Prior research has reported that integrative medicine (IM) therapies reduce pain in inpatients, but without controlling for important variables. Here, the authors extend prior research by assessing pain reduction while accounting for each patient's pain medication status and clinical population. Methods: The initial data set consisted of 7,106 inpatient admissions, aged ≥18 years, between July 16, 2012, and December 15, 2014. Patients' electronic health records were used to obtain data on demographic, clinical measures, and pain medication status during IM. Results: The final data set included first IM therapies delivered during 3,635 admissions. Unadjusted average pre-IM pain was 5.33 (95% confidence interval [CI]: 5.26 to 5.41) and post-IM pain was 3.31 (95% CI: 3.23 to 3.40) on a 0-10 scale. Pain change adjusted for severity of illness, clinical population, sex, treatment, and pain medication status during IM was significant and clinically meaningful with an average reduction of -1.97 points (95% CI: -2.06 to -1.86) following IM. Adjusted average pain was reduced in all clinical populations, with largest and smallest pain reductions in maternity care (-2.34 points [95% CI: -2.56 to -2.14]) and orthopedic (-1.71 points [95% CI: -1.98 to -1.44]) populations. Pain medication status did not have a statistically significant association on pain change. Decreases were observed regardless of whether patients were taking narcotic medications and/or nonsteroidal anti-inflammatory drugs versus no pain medications. Conclusions: For the first time, inpatients receiving IM reported significant and clinically meaningful pain reductions during a first IM session while accounting for pain medications and across clinical populations. Future implementation research should be conducted to optimize identification/referral/delivery of IM therapies within hospitals. Clinical Trials.gov #NCT02190240.

Efficacy and safety of acupuncture treatment as an adjunctive therapy after knee replacement: Single-center, pragmatic, randomized, assessor blinded, pilot study

INTRODUCTION

Total knee replacement (TKR) is a surgical procedure that is being increasingly performed as a result of population aging and the increased average human life expectancy in South Korea. Consistent with the growing number of TKR procedures, the number of patients seeking acupuncture for relief from adverse effects, effective pain management, and the enhancement of rehabilitative therapy effects and bodily function after TKR has also been increasing. Thus, an objective examination of the evidence regarding the safety and efficacy of acupuncture treatments is essential. The aim of this study is to verify the hypothesis that the concurrent use of acupuncture treatment and usual care after TKR is more effective, safe, and cost-effective for the relief of TKR symptoms than usual care therapy alone.

METHODS/DESIGN

This is an open-label, parallel, assessor-blinded randomized controlled trial that includes 50 patients with TKR. After screening the patients and receiving informed consent, the patients are divided into two groups (usual care + acupuncture group and usual care group); the patients will then undergo TKR surgery and will be hospitalized for 2 weeks. The patients will receive a total of 8 acupuncture treatments over 2 weeks after surgery and will be followed up at 3, 4, and 12 weeks after the end of the intervention. The primary outcome is assessed using the Korean version of the Western Ontario and McMaster Universities Arthritis Index (K-WOMAC), and the secondary outcome is measured using the Numerical Rating Scale (NRS), Risk of Fall, and Range of Motion (ROM). Moreover, the cost per quality-adjusted life years (QALYs) is adopted as a primary economic outcome for economic evaluation, and the cost per NRS is adopted as a secondary economic outcome.

ETHICS AND DISSEMINATION

This trial has received complete ethical approval from the Ethics Committee of Catholic Kwandong University International St. Mary's Hospital (IS17ENSS0063). We intend to submit the results to a peer-reviewed journal and/or conferences.

Periarticular needle-based therapies can cause periprosthetic knee infections

Periarticular needle-based therapies such as dry needling, acupuncture, and genicular nerve radiofrequency ablation are becoming more popular for treatment of knee osteoarthritis. These therapies are also being used after total knee arthroplasty for persistent postoperative pain. Although limited published evidence exists for the risk of periprosthetic joint infection after these procedures, we describe one case of periprosthetic joint infection developing shortly after dry needling and another case developing shortly after genicular nerve blocks. We present details of these 2 cases along with a review of the literature regarding the use of periarticular needle-based therapies after total knee arthroplasty.

Complementary and Alternative Medicine for Postoperative Pain: A Systematic Review

BACKGROUND

The treatment of postoperative pain is an ongoing challenge for orthopaedic surgeons. Poorly controlled pain is associated with poorer patient outcomes, and the prescription of opioids may lead to prolonged, nonmedical use. Complementary and alternative medicine is widely adopted by the general public, and its use in chronic musculoskeletal pain conditions has been studied; however, its efficacy in a postoperative context has not yet been established.

METHODS

We conducted a systematic literature review of 10 databases to identify all relevant publications. We extracted variables related to pain measurement and postoperative opioid prescriptions.

RESULTS

We identified 8 relevant publications from an initial pool of 2,517 items. Of these, 5 were randomized studies and 3 were nonrandomized studies. All 8 studies addressed postoperative pain, with 5 showing significant decreases (p < 0.05) in postoperative pain. Also, 5 studies addressed postoperative opioid use, with 2 showing significant differences (p < 0.05) in opioid consumption. Substantial heterogeneity among the studies precluded meta-analysis. No articles were found to be free of potential bias.

CONCLUSIONS

Currently, there is insufficient evidence to determine the efficacy of complementary and alternative medicines for postoperative pain management or as an alternative to opioid use following orthopaedic surgery.

LEVEL OF EVIDENCE

Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.

Pain Management for Orthopedic Patients; Closing the Gap

Total joint replacement (TJR) is one of the most commonly performed and painful surgeries in the United States. Over the past few decades, regulatory changes increased the use of oral narcotics as a first-line treatment of this population. In the current opioid crisis, new pain management techniques and therapies have emerged. Research of current therapies, their effectiveness, and emerging best practices are discussed. Clear, thoughtful, and thorough education is an essential next step for closing the gap of the pain experience. Specifically, education of the frontline nurses, patients, and their caregivers on pain reduction techniques is essential.

Association of Cost and Medical Service Satisfaction with Korean and Conventional Medicine Use before and after Surgery in Postsurgical Patients: A Questionnaire Survey of Korean Patients with Postsurgical Pain Visiting Korean Medicine Hospitals

This study aimed to assess the costs, health status, and medical service satisfaction with Korean and conventional medicine use before and after surgery of patients visiting Korean medicine hospitals for postsurgical musculoskeletal pain. The study population comprised patients who visited KM hospitals for the first time between June and November 2017 for persistent or recurrent pain and discomfort after low back, neck, shoulder, or knee surgery. Various validated questionnaires were used to collect data. A total of 100 participants were enrolled, and the majority had undergone low back surgery (n = 82). The participants had received 1.3 ± 0.7 magnetic resonance imaging (MRI) examinations and 2.4 ± 2.8 X-rays before surgery. Conventional interventions used before surgery were physical therapy (43%), medications (34%), and injections (28%), in descending order, while 48% of patients reported having received acupuncture 51.3 ± 81.1 times. The mean satisfaction score for surgery was 5.5 ± 2.8 points based on a 9-point Likert scale, while that for KM-based interventions was 6.3 ± 1.7 points. With respect to health-related information, the mean scores were 6.0 ± 2.2 points on the Numeric Rating Scale (NRS), 0.6 ± 0.2 points on the 5-Level EuroQol-5 Dimension (EQ-5D-5L), and 15.3 ± 10.2 on Beck's Depression Index II (BDI-II). The mean score on the Oswestry Disability Index (ODI) in patients with low back pain was 40.1 ± 19.2 points. Work impairment, as measured using the Work Productivity and Activity Impairment Questionnaire: General Health (WPAI-GH), was 62.5 ± 47.8%, while activity impairment was 5.9 ± 2.6%. Participants tended to show low satisfaction regarding surgery and high preference for KM-based interventions. In particular, low back surgery patients reported high ODI scores, indicating high dysfunctional levels and poor prognosis after surgery. It can be inferred that it is therefore important to provide appropriate presurgical and postsurgical care for patients with musculoskeletal pain to improve pain, function, and quality of life.

No Effect of Acupuncture as Adjunctive Therapy for Patients with Total Knee Replacement: A Randomized Controlled Trial

Objective

Acupuncture is a low risk option in pain management following total knee replacement as an alternative to opioid analgesics. Therefore, the benefit of acupuncture as adjunct to an exercise program was investigated. Furthermore, the modifying effect of previous benefit from acupuncture was explored.

Design

Three weeks postoperatively, eligible patients were randomized to acupuncture and exercises or exercises alone.

Setting

An outpatient rehabilitation centre in the municipality of Copenhagen, Denmark.

Subjects

A total of 172 patients were included.

Methods

Main outcome was proportion of patients that reported a clinically important change in pain at night following each treatment. Secondary outcomes were change in disability measured after termination of the course of treatment and at three months follow-up. Also consumption of medication and walking distance after termination of the course of treatment were assessed.

Results

No additional benefit of acupuncture was found on any of the main outcomes. Between-group differences were non-significant in proportions of patients with a clinically important reduction of night pain (Relative Risk: 0.98; 95% Confidence Interval (CI): 0.86-1.11) or evening pain (Relative Risk: 0.94; 95% CI: 0.81-1.0.

Conclusions

Our results do not support the addition of acupuncture to routine rehabilitation. Previous benefit from acupuncture was not able to identify those likely to respond to acupuncture. Future studies to investigate whether subgroups of patients would benefit from acupuncture are needed.

Effectiveness of Perioperative Auricular Therapy on Postoperative Pain after Total Hip Arthroplasty: A Systematic Review and Meta-Analysis of Randomised Controlled Trials

Auricular therapy (AT) is a conventional therapy in traditional Chinese medicine. However, the effectiveness of perioperative AT in pain treatment after total hip arthroplasty (THA) is still controversial. Nine randomised controlled trials (RCTs) involving 605 patients who have undergone THA with or without AT from inception to March 2018 were collected and included in this study by searching more than 12 databases (e.g., PubMed, Excerpta Medica Database, and Cochrane Library). A random-effects model that pooled seven articles showed that the visual analogue scale (VAS) in the AT group was lower than that of the control group at each postoperative time point in patients after THA, except at the time points of 6 and 36 h. The intraoperative body mass-adjusted fentanyl amount in the AT group was also lower than that of the control group in two trials. The other outcomes (time to first analgesic request and incidence of postoperative nausea and vomiting, perioperative bradycardia, and transitory hypotension) showed insignificant difference. Then, subgroup analysis showed similar results to those of the total articles with the term “VAS”. Regression analysis found that the prolonged time after the operation decreased the difference in VAS between the two groups. Although all the outcomes were assessed as very low to low in the GRADE system, evidence on the effectiveness of perioperative AT in pain treatment after total hip replacement was positive.

Acupuncture's Role in Solving the Opioid Epidemic: Evidence, Cost-Effectiveness, and Care Availability for Acupuncture as a Primary, Non-Pharmacologic Method for Pain Relief and Management-White Paper 2017

The United States (U.S.) is facing a national opioid epidemic, and medical systems are in need of non-pharmacologic strategies that can be employed to decrease the public's opioid dependence. Acupuncture has emerged as a powerful, evidence-based, safe, cost-effective, and available treatment modality suitable to meeting this need. Acupuncture has been shown to be effective for the management of numerous types of pain conditions, and mechanisms of action for acupuncture have been described and are understandable from biomedical, physiologic perspectives. Further, acupuncture's cost-effectiveness can dramatically decrease health care expenditures, both from the standpoint of treating acute pain and through avoiding addiction to opioids that requires costly care, destroys quality of life, and can lead to fatal overdose. Numerous federal regulatory agencies have advised or mandated that healthcare systems and providers offer non-pharmacologic treatment options for pain. Acupuncture stands out as the most evidence-based, immediately available choice to fulfil these calls. Acupuncture can safely, easily, and cost-effectively be incorporated into hospital settings as diverse as the emergency department, labor and delivery suites, and neonatal intensive care units to treat a variety of commonly seen pain conditions. Acupuncture is already being successfully and meaningfully utilized by the Veterans Administration and various branches of the U.S. Military, in some studies demonstrably decreasing the volume of opioids prescribed when included in care.

Cost Savings from Reducing Pain Through the Delivery of Integrative Medicine Program to Hospitalized Patients

OBJECTIVES

An important task facing hospitals is improving pain management without raising costs. Integrative medicine (IM), a promising nonpharmacologic pain management strategy, is yet to be examined for its cost implications in an inpatient setting. This institution has had an inpatient IM department for over a decade. The purpose was to examine the relationship between changes in patients' pain, as a result of receiving IM therapy, and total cost of care during an inpatient hospital admission.

DESIGN

In this retrospective analysis, data from an EPIC-based electronic health record (EHR) patient demographics, length of stay (LOS), and All Patient Refined Diagnosis Related Groups (APR-DRG) severity of illness measures were utilized. IM practitioners collected and entered patient-reported pain scores into the EHR. The authors regressed the demographic, change in pain, LOS, and APR-DRG variables with changes in pain on total cost for the hospital admission. To estimate cost savings to the hospital, they computed the average reduction in cost associated with reduction in pain by multiplying the coefficient for change in pain by average total cost.

SETTING/LOCATION

A large, tertiary care hospital in Minneapolis, MN.

SUBJECTS

Adult inpatient admissions, 2730, during the study period where patients received IM for pain and met eligibility criteria.

INTERVENTION

IM services provided to inpatients.

OUTCOME MEASURES

Change in pain on an 11-point numeric rating scale before and after initial IM sessions; total costs for hospital admissions.

RESULTS

Both LOS and age were found to increase cost, as did being white, male, married, and having APR-DRG severity coded as extreme. For patients receiving IM therapies, pain was reduced by an average of 2.05 points and this pain reduction was associated with a cost savings of $898 per hospital admission.

CONCLUSIONS

For patients receiving IM therapies, pain was significantly reduced and costs were lowered by about 4%.

Clinical and Radiographic Alterations in Bilateral Avascular Necrosis of the Femoral Head Following Laser Acupuncture: A Case Report

Introduction: Avascular necrosis (AVN) of the femoral head is an increasingly common cause of musculoskeletal disability with unknown etiology. Traumatic and non-traumatic factors can be effective in its occurrence. About 50% of cases are bilateral. The underlying treatment is prosthetic replacement surgical procedure. Case Presentation: We report a case of bilateral AVN of femoral heads who was a candidate for prosthetic replacement surgery but improved significantly, using laser acupuncture. The patient was a 55-year-old woman with a diagnosis of bilateral osteonecrosis of the femoral head for five years. As the patient declined the surgical option, laser acupuncture was started for pain control. Regarding the signs of bilateral femoral head recovery (according to the MRI scan criteria), a total of 3 courses of laser acupuncture (each course was 20 sessions) with 2 months intervals was performed. Ten acupuncture points: Li4, Li11, St36, SP6, LIV3, GB4, GB5, GB6, GB13, GB14, GB20, GB30, GB31, GB34, were irradiated bilaterally using red 650 nm laser, 100 mW, 1505 Hz frequency, duty cycle 50 3 J/point and near infrared 810 nm laser, 100 mW, 1705 Hz frequency, duty cycle 50 3 J/point, for 2 minutes. The patient received 3 laser therapy courses. During the first-course, laser therapy was done every other day to reduce pain. For the second and third courses, according to pain decrease, therapy was done every week. Results: The results of the MRI scans and x-ray studies show progressive regeneration of the right femoral head from VI to B II and of the left from V to C II (based on the standard table of Pennsylvania). Conclusion: It seems that this procedure may be mentioned in future research projects, especially in cases with high risks of surgery.

Drug-Free Interventions to Reduce Pain or Opioid Consumption After Total Knee Arthroplasty: A Systematic Review and Meta-analysis

Importance

There is increased interest in nonpharmacological treatments to reduce pain after total knee arthroplasty. Yet, little consensus supports the effectiveness of these interventions.

Objective

To systematically review and meta-analyze evidence of nonpharmacological interventions for postoperative pain management after total knee arthroplasty.

Data Sources

Database searches of MEDLINE (PubMed), EMBASE (OVID), Cochrane Central Register of Controlled Trials (CENTRAL), Cochrane Database of Systematic Reviews, Web of Science (ISI database), Physiotherapy Evidence (PEDRO) database, and ClinicalTrials.gov for the period between January 1946 and April 2016.

Study Selection

Randomized clinical trials comparing nonpharmacological interventions with other interventions in combination with standard care were included.

Data Extraction and Synthesis

Two reviewers independently extracted the data from selected articles using a standardized form and assessed the risk of bias. A random-effects model was used for the analyses.

Main Outcomes and Measures

Postoperative pain and consumption of opioids and analgesics.

Results

Of 5509 studies, 39 randomized clinical trials were included in the meta-analysis (2391 patients). The most commonly performed interventions included continuous passive motion, preoperative exercise, cryotherapy, electrotherapy, and acupuncture. Moderate-certainty evidence showed that electrotherapy reduced the use of opioids (mean difference, -3.50; 95% CI, -5.90 to -1.10 morphine equivalents in milligrams per kilogram per 48 hours; P = .004; I2 = 17%) and that acupuncture delayed opioid use (mean difference, 46.17; 95% CI, 20.84 to 71.50 minutes to the first patient-controlled analgesia; P < .001; I2 = 19%). There was low-certainty evidence that acupuncture improved pain (mean difference, -1.14; 95% CI, -1.90 to -0.38 on a visual analog scale at 2 days; P = .003; I2 = 0%). Very low-certainty evidence showed that cryotherapy was associated with a reduction in opioid consumption (mean difference, -0.13; 95% CI, -0.26 to -0.01 morphine equivalents in milligrams per kilogram per 48 hours; P = .03; I2 = 86%) and in pain improvement (mean difference, -0.51; 95% CI, -1.00 to -0.02 on the visual analog scale; P < .05; I2 = 62%). Low-certainty or very low-certainty evidence showed that continuous passive motion and preoperative exercise had no pain improvement and reduction in opioid consumption: for continuous passive motion, the mean differences were -0.05 (95% CI, -0.35 to 0.25) on the visual analog scale (P = .74; I2 = 52%) and 6.58 (95% CI, -6.33 to 19.49) opioid consumption at 1 and 2 weeks (P = .32, I2 = 87%), and for preoperative exercise, the mean difference was -0.14 (95% CI, -1.11 to 0.84) on the Western Ontario and McMaster Universities Arthritis Index Scale (P = .78, I2 = 65%).

Conclusions and Relevance

In this meta-analysis, electrotherapy and acupuncture after total knee arthroplasty were associated with reduced and delayed opioid consumption.

Assessing the Impact of Acupuncture on Pain, Nausea, Anxiety, and Coping in Women Undergoing a Mastectomy

PURPOSE/OBJECTIVES

To compare the effect of acupuncture to a standard-of-care (control) group on pain, nausea, anxiety, and ability to cope. 
.

DESIGN

Pilot randomized, controlled trial. 
.

SETTING

Abbott Northwestern Hospital, a large, urban, tertiary care hospital in Minneapolis, Minnesota.
.

SAMPLE

30 adult women undergoing surgery for breast cancer.
.

METHODS

Women were randomly assigned to two hospital-based acupuncture treatments versus usual care after breast cancer surgery. Pain, nausea, anxiety, and the patient's ability to cope pre- and post-treatment were compared within and between groups at two different time points postoperatively. 
.

MAIN RESEARCH VARIABLES

Mean change in pain, nausea, anxiety, and ability to cope by treatment group.
.

FINDINGS

Compared to women assigned to the control group, women who received acupuncture reported a statistically significant greater reduction in pain, nausea, anxiety, and increase in ability to cope on the first postoperative day and in pain on the second postoperative day following mastectomy surgery.
.

CONCLUSIONS

Acupuncture delivered postoperatively in the hospital after mastectomy can reduce the severity of symptoms experienced, as well as increase the patient's ability to cope with her symptoms. However, before implementation as a standard of care, further research needs to be conducted.
.

IMPLICATIONS FOR NURSING

Acupuncture adds a nonpharmacologic intervention for symptom management in women undergoing mastectomies for breast cancer.

Practitioner Perspectives on Delivering Integrative Medicine in a Large, Acute Care Hospital

Background. We describe the process and challenges of delivering integrative medicine (IM) at a large, acute care hospital, from the perspectives of IM practitioners. To date, minimal literature that addresses the delivery of IM care in an inpatient setting from this perspective exists. Methods. Fifteen IM practitioners were interviewed about their experience delivering IM services at Abbott Northwestern Hospital (ANW), a 630-bed tertiary care hospital. Themes were drawn from codes developed through analysis of the data. Results. Analysis of interview transcripts highlighted challenges of ensuring efficient use of IM practitioner resources across a large hospital, the IM practitioner role in affecting patient experiences, and the ways practitioners navigated differences in IM and conventional medicine cultures in an inpatient setting. Conclusions. IM practitioners favorably viewed their role in patient care, but this work existed within the context of challenges related to balancing supply and demand for services and to integrating an IM program into the established culture of a large hospital. Hospitals planning IM programs should carefully assess the supply and demand dynamics of offering IM in a hospital, advocate for the unique IM practitioner role in patient care, and actively support integration of conventional and complementary approaches.

Complementary and Alternative Therapies in Amyotrophic Lateral Sclerosis

Given the severity of their illness and lack of effective disease-modifying agents, it is not surprising that most patients with amyotrophic lateral sclerosis (ALS) consider trying complementary and alternative therapies. Some of the most commonly considered alternative therapies include special diets, nutritional supplements, cannabis, acupuncture, chelation, and energy healing. This article reviews these in detail. The authors also describe 3 models by which physicians may frame discussions about alternative therapies: paternalism, autonomy, and shared decision making. Finally, the authors review a program called ALSUntangled, which uses shared decision making to review alternative therapies for ALS.

Healing Environments: Integrative Medicine and Palliative Care in Acute Care Settings

Conventional medicine is excellent at saving lives; however, it has little to offer to address the physical, mental, and emotional distress associated with life-threatening or life-limiting disease. An integrative approach to palliative care in acute care settings can meet this need by creating healing environments that support patients, families, and health care professionals. Mindful use of language enhances the innate healing response, improves communication, and invites patients and families to participate in their care. Staff should be offered access to skills training to cultivate compassion and mindful practice to enhance both patient and self-care.
