Access to chiropractic care and the cost of spine conditions among older adults.

OBJECTIVES: Chiropractic care is a service that operates outside of the conventional medical system and is reimbursed by Medicare. Our objective was to examine the extent to which accessibility of chiropractic care affects spending on medical spine care among Medicare beneficiaries. STUDY DESIGN: Retrospective cohort study that used beneficiary relocation as a quasi-experiment. METHODS: We used a combination of national data on provider location and Medicare claims to perform a quasi-experimental study to examine the effect of chiropractic care accessibility on healthcare spending. We identified 84,679 older adults enrolled in Medicare with a spine condition who relocated once between 2010 and 2014. For each year, we measured accessibility using the variable-distance enhanced 2-step floating catchment area method. Using data for the years before and after relocation, we estimated the effect of moving to an area of lower or higher chiropractic accessibility on spine-related spending adjusted for access to medical physicians. RESULTS: There are approximately 45,000 active chiropractors in the United States, and local accessibility varies considerably. A negative dose-response relationship was observed for spine-related spending on medical evaluation and management as well as diagnostic imaging and testing (mean differences, $20 and $40, respectively, among those exposed to increasingly higher chiropractic accessibility; P <.05 for both). Associations with other types of spine-related spending were not significant. CONCLUSIONS: Among older adults, access to chiropractic care may reduce medical spending on services for spine conditions.

A cost-minimization analysis in minimally invasive spine surgery using a national cost scale method.

INTRODUCTION: The last decade has seen the emergence of minimally invasive spine surgery. However, there is still no consensus on whether percutaneous osteosynthesis (PO) or open surgery (OS) is more cost-effective in treatment of traumatic fractures and degenerative lesions. The objective of this study is to compare the clinical results and hospitalization costs of OS and PO for degenerative lesions and thoraco-lumbar fractures. METHODS: This cost-minimization study was performed in patients undergoing OS or PO on a 36-month period. Patient data, surgical and clinical results, as well as cost data were collected and analyzed. The financial costs were calculated based on diagnosis related group reimbursement and the French national cost scale, enabling the evaluation of charges for each hospital stay. RESULTS: 46 patients were included in this cost analysis, 24 patients underwent OS and 22 underwent PO. No significant difference was found between surgical groups in terms of patient's clinical features and outcomes during the patient hospitalization. The use of PO was significantly associated with a decrease in Length Of Stay (LOS). The cost-minimization revealed that PO is associated with decreased hospital charges and shorten LOS for patients, with similar clinical outcomes and medical device cost to OS. CONCLUSIONS: This medico-economic study has leaded to choose preferentially the use of minimally invasive surgery techniques. This study also illustrates the discrepancy between the national health system reimbursement and real hospital charges. The medico-economic is becoming critical in the current context of sustainable health resource allocation.

Where the United States spends its spine dollars: expenditures on different ambulatory services for the management of back and neck conditions.

STUDY DESIGN: Serial, cross-sectional, nationally representative surveys of noninstitutionalized US adults. OBJECTIVE: To examine expenditures on common ambulatory health services for the management of back and neck conditions. SUMMARY OF BACKGROUND DATA: Although it is well recognized that national costs associated with back and neck conditions have grown considerably in recent years, little is known about the costs of care for specific ambulatory health services that are used to manage this population. METHODS: We used the Medical Expenditure Panel Survey to examine adult (aged 18 yr or older) respondents from 1999 to 2008 who sought ambulatory health services for the management of back and neck conditions. We used complex survey design methods to make national estimates of mean inflation-adjusted annual expenditures on medical care, chiropractic care, and physical therapy per user for back and neck conditions. RESULTS: Approximately 6% of US adults reported an ambulatory visit for a primary diagnosis of a back or neck condition (13.6 million in 2008). Between 1999 and 2008, the mean inflation-adjusted annual expenditures on medical care for these patients increased by 95% (from $487 to $950); most of the increase was accounted for by increased costs for medical specialists, as opposed to primary care physicians. During the study period, the mean inflation-adjusted annual expenditures on chiropractic care were relatively stable; although physical therapy was the most costly service overall, in recent years those costs have contracted. CONCLUSION: Although this study did not explore the relative effectiveness of different ambulatory services, recent increasing costs associated with providing medical care for back and neck conditions (particularly subspecialty care) are contributing to the growing economic burden of managing these conditions.

Efficacy and cost-effectiveness of cell saving blood autotransfusion in adult lumbar fusion.

The objective of this study was to explore the use of cell saver blood autotransfusion in spinal surgery and to evaluate the efficacy and cost-effectiveness of cell saver blood autotransfusion during lumbar spine fusion in adults. Specific indications for the use of cell saver in adult lumbar fusion surgery have not yet been clearly determined. A total of 50 consecutive candidates for posterolateral fusion with internal fixation were prospectively randomized into either receiving perioperatively cell saving autotransfusion (Group A: 25 patients) or not (Group B: 25 patients). The use of cell saving technique did not exclude the use of allogenic blood transfusion. Surgical indications were spinal stenosis, spondylolisthesis, adolescent idiopathic scoliosis, degenerative scoliosis and fractures. Medical and financial data were recorded. A cost-analysis was performed. Patients in Group A received 880 +/- 216 mL from cell saver and 175 +/- 202 mL allogenic blood. The patients in Group B received 908 +/- 244 mL allogenic blood. Blood volumes data collected were expressed in mean +/- SD values. The cost of blood transfusion in Group A was 995 +/-euro447 per patient and 1220 +/- 269 in Group B (P < 0.05). In elective lumbar fusion blood requirements can be satisfied with the use of autotransfusion. The use of cell saver appears to be useful and cost-effective during most elective lumbar fusions.

Randomised controlled study in the primary healthcare sector to investigate the effectiveness and safety of auriculotherapy for the treatment of uncomplicated chronic rachialgia: a study protocol.

BACKGROUND: Uncomplicated chronic rachialgia is a highly prevalent complaint, and one for which therapeutic results are contradictory. The aim of the present study is to evaluate the effectiveness and safety of treatment with auriculopressure, in the primary healthcare sector, carried out by trained healthcare professionals via a 30-hour course. METHODS/DESIGN: The design consists of a multi-centre randomized controlled trial, with placebo, with two parallel groups, and including an economic evaluation. Patients with chronic uncomplicated rachialgia, whose GP is considering referral for auriculopressure sensory stimulation, are eligible for inclusion. Sampling will be by consecutive selection, and randomised allocation to one of the two study arms will be determined using a centralised method, following a 1:1 plan (true auriculopressure; placebo auriculopressure). The implants (true and placebo) will be replaced once weekly, and the treatment will have a duration of 8 weeks. The primary outcome measure will be the change in pain intensity, measured on a visual analogue scale (VAS) of 100 mm, at 9 weeks after beginning the treatment. A follow up study will be performed at 6 months after beginning treatment. An assessment will also be made of the changes measured in the Spanish version of the McGill Pain Questionnaire, of the changes in the Lattinen test, and of the changes in quality of life (SF-12). Also planned is an analysis of cost-effectiveness and also, if necessary, a cost-benefit analysis. DISCUSSION: This study will contribute to developing evidence on the use of auriculotherapy using Semen vaccariae [wang bu liu xing] for the treatment of uncomplicated chronic rachialgia.
