RESUMEN

BACKGROUND: Lateral elbow tendinopathy (LET) is a common complaint causing characteristic pain in the lateral elbow and upper forearm, and tenderness of the forearm extensor muscles. It is thought to be an overuse injury and can have a major impact on the patient's social and professional life. The condition is challenging to treat and prone to recurrent episodes. The average duration of a typical episode ranges from 6 to 24 months, with most (89%) reporting recovery by 1 year. OBJECTIVES: This systematic review aims to summarise the evidence concerning the clinical effectiveness and cost-effectiveness of conservative interventions for LET. DATA SOURCES: A comprehensive search was conducted from database inception to 2012 in a range of databases including MEDLINE, EMBASE and Cochrane Databases. METHODS AND OUTCOMES: We conducted an overview of systematic reviews to summarise the current evidence concerning the clinical effectiveness and a systematic review for the cost-effectiveness of conservative interventions for LET. We identified additional randomised controlled trials (RCTs) that could contribute further evidence to existing systematic reviews. We searched MEDLINE, EMBASE, Allied and Complementary Medicine Database, Cumulative Index to Nursing and Allied Health Literature, Web of Science, The Cochrane Library and other important databases from inception to January 2013. RESULTS: A total of 29 systematic reviews published since 2003 matched our inclusion criteria. These were quality appraised using the Assessment of Multiple Systematic Reviews (AMSTAR) checklist; five were considered high quality and evaluated using a Grading of Recommendations, Assessment, Development and Evaluation approach. A total of 36 RCTs were identified that were not included in a systematic review and 29 RCTs were identified that had only been evaluated in an included systematic review of intermediate/low quality. These were then mapped to existing systematic reviews where further evidence could provide updates. Two economic evaluations were identified. LIMITATIONS: The summary of findings from the review was based only on high-quality evidence (scoring of > 5 AMSTAR). Other limitations were that identified RCTs were not quality appraised and dichotomous outcomes were also not considered. Economic evaluations took effectiveness estimates from trials that had small sample sizes leading to uncertainty surrounding the effect sizes reported. This, in turn, led to uncertainty of the reported cost-effectiveness and, as such, no robust recommendations could be made in this respect. CONCLUSIONS: Clinical effectiveness evidence from the high-quality systematic reviews identified in this overview continues to suggest uncertainty as to the effectiveness of many conservative interventions for the treatment of LET. Although new RCT evidence has been identified with either placebo or active controls, there is uncertainty as to the size of effects reported within them because of the small sample size. Conclusions regarding cost-effectiveness are also unclear. We consider that, although updated or new systematic reviews may also be of value, the primary focus of future work should be on conducting large-scale, good-quality clinical trials using a core set of outcome measures (for defined time points) and appropriate follow-up. Subgroup analysis of existing RCT data may be beneficial to ascertain whether or not certain patient groups are more likely to respond to treatments. STUDY REGISTRATION: This study is registered as PROSPERO CRD42013003593. FUNDING: The National Institute for Health Research Health Technology Assessment programme.

RESUMEN

OBJECTIVE: Chronic tendon pathology is a soft tissue condition commonly seen in chiropractic practice. Tendonitis, tendinosis, and tendinopathy are terms used to describe this clinical entity. The purpose of this article is to review interventions commonly used by doctors of chiropractic when treating tendinopathy. METHODS: The Scientific Commission of the Council on Chiropractic Guidelines and Practice Parameters (CCGPP) was charged with developing literature syntheses, organized by anatomical region, to evaluate and report on the evidence base for chiropractic care. This article is the outcome of this charge. As part of the CCGPP process, preliminary drafts of these articles were posted on the CCGPP Web site www.ccgpp.org (2006-8) to allow for an open process and the broadest possible mechanism for stakeholder input. A literature search was performed using the PubMed; Cumulative Index to Nursing and Allied Health Literature; Index to Chiropractic Literature; Manual, Alternative, and Natural Therapy Index System; National Guidelines Clearinghouse; Database of Abstracts of Reviews of Effects; and Turning Research Into Practice databases. The inclusion criteria were manual therapies, spinal manipulation, mobilization, tendonitis, tendinopathy, tendinosis, cryotherapy, bracing, orthotics, massage, friction massage, transverse friction massage, electrical stimulation, acupuncture, exercise, eccentric exercise, laser, and therapeutic ultrasound. RESULTS: There is evidence that ultrasound therapy provides clinically important improvement in the treatment of calcific tendonitis. There is limited evidence of the benefit of manipulation and mobilization in the treatment of tendinopathy. Limited evidence exists to support the use of supervised exercise, eccentric exercise, friction massage, acupuncture, laser therapy, use of bracing, orthotics, and cryotherapy in the treatment of tendinopathy. CONCLUSION: Chiropractors often provide a number of conservative interventions commonly used to treat tendinopathy.

RESUMEN

Acute medical conditions commonly seen by physician assistants (PAs) or physicians were assigned costs for all resources used to treat an episode of illness. Included in the analysis were data on the provider of record for the episode, patient characteristics, health status, diagnosis, treatment, referrals, medication, imaging, laboratory studies, and return visits. In every medical condition managed by PAs, the total episode cost was less than a similar episode managed by a physician, regardless of patient age, gender, health status, and department. Few differences emerged in the use of resources and the rate of return visits for a diagnosis between physicians and PAs. In this setting PAs appear to be cost-effective from an employment standpoint.

RESUMEN

OBJECTIVE: To determine the actual costs of extracorporeal shock wave therapy (ESWT) in patients with tendinitis of the supraspinatus muscle. METHODS: A comparison of the costs of surgical treatment versus the costs for ESWT was made. The total accrued costs were determined 12 weeks after intervention, using a sample group of 60 patients with calcifying or noncalcifying tendinitis of the supraspinatus muscle. RESULTS: The costs per case ranged from EUR 2,700 to EUR 4,300 per patient for ESWT and from EUR 13,400 to EUR 23,450 for surgical treatment, dependent on the method of calculation. Approximately 65% of the per-patient cost is attributable to productivity losses in the workplace. CONCLUSIONS: In comparable short-term results, costs for operative treatment are 5-7 times higher than for ESWT. The greater trauma caused by an operative procedure leads to patients being off work for a longer period and thus a correspondingly higher social economic burden.

RESUMEN

Seventy-five consecutive anterior acromioplasties were performed in 74 patients with chronic inflammation of the supraspinatus tendon caused by the impingement syndrome. Thirty-six patients (49%) had filed workers' compensation claims (group 1), 21 patients (28%) were involved in accident litigation (group 2), and 17 patients (23%) had no financial gain associated with their shoulder pain (group 3). The patients were followed up for a minimum of 12 months after surgery (range 12 to 48 months). Sixty-one patients (82%) had excellent results, 11 patients (15%) had good results, and 2 patients (3%) failed to improve from surgery. Ninety-one percent of employed patients were able to return to full employment. Although group 1 patients required a significantly longer time to return to work (average 14.2 weeks vs. 4.7 weeks in group 2 and 2.5 weeks in group 3), these patients were all involved in heavy labor demanding a more complete return of shoulder endurance. Satisfactory pain relief and return to preinjury work activities can be achieved by acromioplasty in patients who have the potential for secondary gain.

RESUMEN

OBJECTIVE: To compare the effectiveness of arthroscopic surgery, a supervised exercise regimen, and placebo soft laser treatment in patients with rotator cuff disease (stage II impingement syndrome). DESIGN: Randomised clinical trial. SETTING: Hospital departments of orthopaedics and of physical medicine and rehabilitation. PATIENTS: 125 patients aged 18-66 who had had rotator cuff disease for at least three months and whose condition was resistant to treatment. INTERVENTIONS: Arthroscopic subacromial decompression performed by two experienced surgeons; exercise regimen over three to six months supervised by one experienced physiotherapist; or 12 sessions of detuned soft laser treatment over six weeks. MAIN OUTCOME MEASURES: Change in the overall Neer shoulder score (pain during previous week and blinded evaluation of function and range of movement by one clinician) after six months. RESULTS: No differences were found between the three groups in duration of sick leave and daily intake of analgesics. After six months the difference in improvement in overall Neer score between surgery and supervised exercises was 4.0 (95% confidence interval -2 to 11) and 2.0 (-1.4 to 5.4) after adjustment for sex. The condition improved significantly compared with placebo in both groups given the active treatments. Treatment costs were higher for those given surgery (720 pounds v 390 pounds). CONCLUSIONS: Surgery or a supervised exercise regimen significantly, and equally, improved rotator cuff disease compared with placebo.

RESUMEN

The present study uses data from a national, community-based survey to compare the social impact of and medical care use due to 4 musculoskeletal conditions: rheumatoid arthritis, osteoarthritis, lower back pain, and tendinitis. The study also compares the impacts experienced by persons with these conditions with those experienced by a sample of persons having a broader range of musculoskeletal conditions, and by an age-adjusted sample representing the entire U.S. population. Rheumatoid arthritis leads to the most frequent use of physician services; lower back pain results in the most hospitalizations and surgery. Rheumatoid arthritis also causes the most restriction in activity. We found that as a broad group, persons with musculoskeletal disease experience about the same amount of restriction in activity and use about the same amount of medical care as U.S. citizens as a whole. This study demonstrates that health planning on the basis of specific musculoskeletal conditions is necessary to serve the disparate needs of persons with particular, discrete conditions.
