Reductions in pain medication use associated with traditional Chinese medicine for chronic pain.

ABSTRACT:

Context

Participants in a randomized trial of traditional Chinese medicine (TCM) for temporomandibular joint dysfunction (TMD) had a linear decline in pain over 16 TCM visits.

Objective

To investigate whether reductions in pain among participants receiving TCM can be explained by increased use of pain medications, or whether use of pain medications also declined in this group.

Design

One hundred sixty-eight participants with TMD were treated with TCM or enhanced self-care according to a stepped-care design. Those for whom self-care failed were sequentially randomized to further self-care or TCM. This report includes 111 participants during their first 16 TCM visits. The initial 8 visits occurred more than once a week; participants and practitioners determined the frequency of subsequent visits.

Outcome measures

Average pain (visual analog scale, range 0-10) and morphine and aspirin dose equivalents.

Results

The sample was 87% women and the average age was 44 ± 13 years. Average pain of narcotics users (n = 21) improved by 2.73 units over 16 visits (p < 0.001). Overall narcotics use trended downward until visit 11 (-3.27 doses/week, p = 0.156), and then trended upward until week 16 (+4.29 doses/week, p = 0.264). Among those using narcotics, use of nonsteroidal anti-inflammatory drugs (NSAIDs) declined linearly over visits 1-16 (-1.94 doses/week, p = 0.002).Among the top quartile of NSAID-only users (n = 22), average pain decreased linearly over 16 visits (-1.52 units, p = 0.036). Overall NSAID doses/week declined between visits 1 and 7 (-9.95 doses/week, p < 0.001) and then remained stable through 16 visits. NSAID use also declined among the third quartile (n = 23) and remained low and stable among the lower half (sorted by total intake) of NSAID users.

Conclusions

Among the heaviest NSAID users, we observed a short-term reduction in NSAID use that was sustained as TCM visits became less frequent. There was no indication that pain reduction during TCM treatment was influenced by drug use.

Project description:Background Extensive studies have been conducted to evaluate the pain relief effect of traditional Chinese medicine (TCM) interventions on patients with low back pain, including in China. However, there is a dearth in the literature documenting the diverse goals of TCM interventions, let alone the overall effect of such interventions. In this study, the goal attainment scaling (GAS) method was adopted to evaluate individualised TCM interventions on chronic low back pain. Methods A pre-post intervention study was conducted on patients with chronic low back pain who received individualised TCM interventions in community health services. The study was undertaken in three community health centres in Hangzhou of China. A total of 165 eligible patients were invited, and 150 participated in the study, including 136 who completed both pre- and postintervention surveys. Each participant was asked to identify three to five intended goals from a pool of 26 outcome indicators and their corresponding expectations of these goals prior to the TCM interventions. Their conditions were rated against the selected indicators on a self-report five-point Likert scale before and after the TCM interventions, respectively. Gaps between the actual conditions and the expected goals were summed up for each participant and converted into a standardised GAS score, with a higher score indicating higher achievements, and 50 indicting patient expectations were met. Linear regression models were established to determine the factors associated with the pre-post GAS changes after adjustment for variations in other variables. Results On average, an increase of 14.99 (SD?=?9.81) in the GAS scores was achieved. This resulted in a mean GAS score of 48.33 (SD?=?9.74) after the TCM interventions, falling slightly short (<2) of patient expectations. The multivariate linear regression models revealed that local residents, the retired, and those who perceived lower professional competency of their attending doctors had a smaller increase in the GAS scores after adjustment for variations in other variables. Conclusion The individualised TCM interventions can help patients with low back pain to achieve their expected goals as measured by the GAS. Further studies are needed to better understand how patients set up their goals and the professional competency requirements to meet patient expectations.

Project description:This dual-site study sought to identify the appropriate role for traditional Chinese medicine (TCM; acupuncture and herbs) in conjunction with a validated psychosocial self-care (SC) intervention for treating chronic temporomandibular disorders (TMD)-associated pain. Participants with Research Diagnostic Criteria for Temporomandibular Disorders-confirmed TMD (n = 168) entered a stepped-care protocol that began with a basic TMD class. At weeks 2 and 10, patients receiving SC whose worst facial pain was above predetermined levels were reallocated by minimization to SC or TCM with experienced practitioners. Characteristic facial pain (CFP: mean of worst pain, average pain when having pain, and current pain; each visual analog scale [VAS] 0-10) was the primary outcome. Social activity interference (VAS 0-10) was a secondary outcome. Patients were monitored for safety. TCM provided significantly greater short-term (8-week) relief than SC (CFP reduction difference, -.60 [standard deviation of the estimate .26], P = .020) and greater reduction in interference with social activities (-.81 [standard deviation of the estimate .33], P = .016). In 2 of 5 treatment trajectory groups, more than two thirds of participants demonstrated clinically meaningful responses (?30% improvement) in pain interference over 16 weeks. This study provides evidence that TMD patients referred for TCM in a community-based model will receive safe treatment that is likely to provide some short-term pain relief and improved quality of life. Similar designs may also apply to evaluations of other kinds of chronic pain. (ClinicalTrials.gov number NCT00856167).This short-term comparative effectiveness study of chronic facial pain suggests that TCM is safe and frequently efficacious alone or subsequent to standard psychosocial interventions. TCM is widely available throughout North America and may provide clinicians and patients with a reasonable addition or alternative to other forms of therapy.

Project description:Background:Traditional, complementary, and alternative medicine (TCAM) has attracted increasing attention in developed countries, but its mainstream status in China, the home of TCAM, is unclear. Over the period of 2004-2016, we analyze the health resources and health resource utilization of traditional medicine in traditional Chinese medicine (TCM) hospitals in China. Methods:Over 2004-2016, we obtained data from all TCM hospitals in all Chinese provinces to create a hospital-based, longitudinal dataset. TCM health resources and their utilization were measured by two outcome variables: (1) primary outcome variables comprising the proportion of TCM physicians, TCM pharmacists, revenue from TCM drugs, and TCM prescriptions and (2) the secondary outcome variables, as proxies of westernization for TCM hospitals, comprising the number of medical equipment above RMB 10,000 and the proportion of surgery in inpatient visits. We used linear regression models with hospital-fixed effects to analyze time trends for the outcome variables. Results:The number of public TCM hospitals remained stable from 2004 to 2016, while the number of private TCM hospitals increased from 294 in 2004 to 1560 in 2016. There was a small percentage increase in the proportion of TCM physicians (0.280%), TCM pharmacists (0.298%), and revenue from Chinese medicines (0.331%) and TCM prescriptions (1.613%) per hospital per year. Chinese drugs accounted for less than a half of the total drug prescriptions, and accordingly, just one-third of the drug revenue was from Chinese medicines at TCM hospitals. The proportions of physicians, pharmacists, revenue from Chinese drug sales, and traditional medicine prescriptions never reach the 60% benchmark target for mainstream in TCM hospitals. As proxies for Western medicine practices in TCM hospitals, the number of medical equipment above RMB 10,000 rapidly rose by over 13 percent per hospital per year, but the proportion of inpatient surgeries declined by 0.830 percentage points per hospital per year, reflecting a mixed trend in the use of Western medicine practices. Conclusion:For the 2004-2016 period, traditional medicine, although making progress towards the mainstream benchmark of 60% TCM services, was still not mainstream at TCM hospitals.
