Efficiency of primary spine care as compared to conventional primary care: a retrospective observational study at an Academic Medical Center.

BACKGROUND: Primary Spine Care (PSC) is an innovative model for the primary management of patients with spine-related disorders (SRDs), with a focus on the use of non-pharmacological therapies which now constitute the recommended first-line approach to back pain. PSC clinicians serve as the initial or early point of contact for spine patients and utilize evidence-based spine care pathways to improve outcomes and reduce escalation of care (EoC; e.g., spinal injections, diagnostic imaging, hospitalizations, referrals to a specialist). The present study examined 6-month outcomes to evaluate the efficiency of care for patients who received PSC as compared to conventional primary care. We hypothesized that patients seen by a PSC clinician would have lower rates of EoC compared to patients who received usual care by a primary care (PC) clinician. METHODS: This was a retrospective observational study. We evaluated 6-month outcomes for two groups seen and treated for an SRD between February 01, 2017 and January 31, 2020. Patient groups were comprised of N = 1363 PSC patients (Group A) and N = 1329 PC patients (Group B). We conducted Pearson chi-square and logistic regression (adjusting for patient characteristics that were unbalanced between the two groups) to determine associations between the two groups and 6-month outcomes. RESULTS: Within six months of an initial visit for an SRD, a statistically significantly smaller proportion of PSC patients utilized healthcare resources for spine care as compared to the PC patients. When adjusting for patient characteristics, those who received care from the PSC clinician were less likely within 6 months of an initial visit to be hospitalized (OR = .47, 95% CI .23-.97), fill a prescription for an opioid analgesic (OR = .43; 95% CI .29-.65), receive a spinal injection (OR = .56, 95% CI .33-.95), or have a visit with a specialist (OR = .48, 95% CI .35-.67) as compared to those who received usual primary care. CONCLUSIONS: Patients who received PSC in an academic primary care clinic experienced significantly less escalation of their spine care within 6 months of their initial visit. The PSC model may offer a more efficient approach to the primary care of spine problems for patients with SRDs, as compared to usual primary care.

Experiences and Attitudes About Chiropractic Care and Prescription Drug Therapy Among Patients With Back Pain: A Cross-Sectional Survey.

OBJECTIVE: The purpose of this study was to examine experiences and attitudes toward care offered by chiropractors and prescription drug therapy offered by medical physicians for patients who have back pain. METHODS: A cross-sectional survey measured patients with back pain (n = 150) seeking care within an academic primary care setting. A survey assessed patient experiences, beliefs, and attitudes regarding chiropractic care and prescription drug therapy. Two samples of patients in the New Hampshire region included 75 patients treated by a doctor of chiropractic (DC) and 75 treated by a medical primary care physician (PCP). The 30-item survey was sent to existing and new patients between February 2019 and January 2020. Between-group comparisons were examined to test rates of reporting and to determine the mean difference in the total number of office visits between the 2 samples. RESULTS: Patients treated by both DCs and PCPs reported high overall satisfaction with chiropractic care received for low back pain with no significant differences between groups. The majority in both groups reported that seeing a DC for back pain made sense to them (95% of patients treated by a DC and 75% of patients treated by a PCP) whereas the minority reported that taking prescription drugs for back pain made sense (25% of patients treated by a DC and 41% of patients treated by a PCP). There was no statistical difference between groups when patients were asked if seeing a chiropractor changed their beliefs or behaviors about taking pain medication. Significant differences were found between groups for agreement that chiropractic care would be a suitable treatment for back pain (79% of patients treated by a DC and 45% of patients treated by a PCP). There were 7% of patients treated by PCP and 23% of the patients treated by DC who agreed that a DC would be the first health care provider they would like to see for their general health needs. CONCLUSIONS: In this sample of patients, patient satisfaction regarding chiropractic care received for back pain was high. There were differences between patient groups about preferences for treatment for back pain. Our results indicate that patients reported that seeing a DC for back pain did not change their beliefs or behaviors regarding prescription drug therapy provided by their medical PCP.

Implementation of the Primary Spine Care Model in a Multi-Clinician Primary Care Setting: An Observational Cohort Study.

OBJECTIVE: The objective of this investigation was to compare the value of primary spine care (PSC) with usual care for management of patients with spine-related disorders (SRDs) within a primary care setting. METHODS: We retrospectively examined existing patient encounter data at 3 primary care sites within a multi-clinic health system. Designated clinicians serve in the role as PSC as the initial point of contact for spine patients, coordinate, and follow up for the duration of the episode of care. A PSC may be a chiropractor, physical therapist, or medical or osteopathic physician who has been trained to provide primary care for patients with SRDs. The PSC model of care had been introduced at site I (Lebanon, New Hampshire); sites II (Bedford, New Hampshire) and III (Nashua, New Hampshire) served as control sites where patients received usual care. To evaluate cost outcomes, we employed a controlled quasi-experimental design for analysis of health claims data. For analysis of clinical outcomes, we compared clinical records for PSC at site I and usual care at sites II and III, all with reference to usual care at site I. We examined clinical encounters occurring over a 24-month period, from February 1, 2016 through January 31, 2018. RESULTS: Primary spine care was associated with reduced total expenditures compared with usual care for SRDs. At site I, average per-patient expenditure was $162 in year 1 and $186 in year 2, compared with site II ($332 in year 1; $306 in year 2) and site III ($467 in year 1; $323 in year 2). CONCLUSION: Among patients with SRDs included in this study, implementation of the PSC model within a conventional primary care setting was associated with a trend toward reduced total expenditures for spine care compared with usual primary care. Implementation of PSC may lead to reduced costs and resource utilization, but may be no more effective than usual care regarding clinical outcomes.

Trends in Insurance Coverage for Complementary Health Care Services.

Introduction: Complementary health care professionals deliver a substantial component of clinical services in the United States, but insurance coverage for many such services may be inadequate. The objective of this project was to follow up on an earlier single-year study with an evaluation of trends in reimbursement for complementary health care services over a 7-year period. Methods: The authors employed a retrospective serial cross-sectional design to analyze health insurance claims for services provided by licensed acupuncturists, chiropractors, and naturopaths in New Hampshire (NH) from 2011 to 2017. They restricted the analyses to claims in nonemergent outpatient settings for Current Procedural Terminology code 99213, which is one of the most commonly used clinical procedure codes across all specialties. They evaluated by year the likelihood of reimbursement, as compared with primary care physicians as the gold standard. A generalized estimating equation model was used to account for within-person correlations among the separate claim reimbursement indicators for individuals used in the analysis, using an exchangeable working covariance structure among claims for the same individual. Reimbursement was defined as payment >0 dollars. Results: The total number of clinical services claimed was 26,725 for acupuncture, 8317 for naturopathic medicine, 2,539,144 for chiropractic, and 1,860,271 for primary care. Initially, likelihood of reimbursement for naturopathic physicians was higher relative to primary care physicians, but was lower from 2014 onward. Odds of reimbursement for both acupuncture and chiropractic claims remained lower throughout the study period. In 2017, as compared with primary care the likelihood of reimbursement was 77% lower for acupuncturists, 72% lower for chiropractors, and 64% lower for naturopaths. Conclusion: The likelihood of reimbursement for complementary health care services is significantly lower than that for primary care physicians in NH. Lack of insurance coverage may result in reduced patient access to such services.

Impact of Chiropractic Care on Use of Prescription Opioids in Patients with Spinal Pain.

OBJECTIVE: Utilization of nonpharmacological pain management may prevent unnecessary use of opioids. Our objective was to evaluate the impact of chiropractic utilization upon use of prescription opioids among patients with spinal pain. DESIGN AND SETTING: We employed a retrospective cohort design for analysis of health claims data from three contiguous states for the years 2012-2017. SUBJECTS: We included adults aged 18-84 years enrolled in a health plan and with office visits to a primary care physician or chiropractor for spinal pain. We identified two cohorts of subjects: Recipients received both primary care and chiropractic care, and nonrecipients received primary care but not chiropractic care. METHODS: We performed adjusted time-to-event analyses to compare recipients and nonrecipients with regard to the risk of filling an opioid prescription. We stratified the recipient populations as: acute (first chiropractic encounter within 30 days of diagnosis) and nonacute (all other patients). RESULTS: The total number of subjects was 101,221. Overall, between 1.55 and 2.03 times more nonrecipients filled an opioid prescription, as compared with recipients (in Connecticut: hazard ratio [HR] = 1.55, 95% confidence interval [CI] = 1.11-2.17, P = 0.010; in New Hampshire: HR = 2.03, 95% CI = 1.92-2.14, P < 0.0001). Similar differences were observed for the acute groups. CONCLUSIONS: Patients with spinal pain who saw a chiropractor had half the risk of filling an opioid prescription. Among those who saw a chiropractor within 30 days of diagnosis, the reduction in risk was greater as compared with those with their first visit after the acute phase.

Association Between Utilization of Chiropractic Services for Treatment of Low Back Pain and Risk of Adverse Drug Events.

OBJECTIVES: Mortality rates due to adverse drug events (ADEs) are escalating in the United States. Analgesics are among the drug classes most often associated with occurrence of an ADE. Utilization of nonpharmacologic chiropractic services for treatment of low back pain could lead to reduced risk of an ADE. The objective of this investigation was to evaluate the association between utilization of chiropractic services and likelihood of an ADE. METHODS: We employed a retrospective cohort design to analyze health insurance claims data from the state of New Hampshire. After inversely weighting each participant by their propensity to be in their cohort, we employed logistic regression to compare recipients of chiropractic services to nonrecipients with regard to likelihood of occurrence of an ADE in an outpatient setting. RESULTS: The risk of an ADE was significantly lower among recipients of chiropractic services as compared with nonrecipients. The adjusted likelihood of an ADE occurring in an outpatient setting within 12 months was 51% lower among recipients of chiropractic services as compared to nonrecipients (OR 0.49; P = .0002). The reported ADEs were nonspecific with regard to drug category in the majority of incidents that occurred in both cohorts. CONCLUSIONS: Among New Hampshire adults with office visits for low back pain, the adjusted likelihood of an ADE was significantly lower for recipients of chiropractic services as compared to nonrecipients. No causal relationship was established between utilization of chiropractic care and risk of an ADE. Future research should employ larger databases, rigorous methods to reduce risk of bias, and more sensitive means of identifying ADEs.

Association Between Utilization of Chiropractic Services for Treatment of Low-Back Pain and Use of Prescription Opioids.

OBJECTIVE: Pain relief resulting from services delivered by doctors of chiropractic may allow patients to use lower or less frequent doses of opioids, leading to reduced risk of adverse effects. The objective of this investigation was to evaluate the association between utilization of chiropractic services and the use of prescription opioid medications. DESIGN: The authors used a retrospective cohort design to analyze health insurance claims data. SETTING: The data source was the all payer claims database administered by the State of New Hampshire. The authors chose New Hampshire because health claims data were readily available for research, and in 2015, New Hampshire had the second-highest age-adjusted rate of drug overdose deaths in the United States. SUBJECTS: The study population comprised New Hampshire residents aged 18-99 years, enrolled in a health plan, and with at least two clinical office visits within 90 days for a primary diagnosis of low-back pain. The authors excluded subjects with a diagnosis of cancer. OUTCOME MEASURES: The authors measured likelihood of opioid prescription fill among recipients of services delivered by doctors of chiropractic compared with nonrecipients. They also compared the cohorts with regard to rates of prescription fills for opioids and associated charges. RESULTS: The adjusted likelihood of filling a prescription for an opioid analgesic was 55% lower among recipients compared with nonrecipients (odds ratio 0.45; 95% confidence interval 0.40-0.47; p < 0.0001). Average charges per person for opioid prescriptions were also significantly lower among recipients. CONCLUSIONS: Among New Hampshire adults with office visits for noncancer low-back pain, the likelihood of filling a prescription for an opioid analgesic was significantly lower for recipients of services delivered by doctors of chiropractic compared with nonrecipients. The underlying cause of this correlation remains unknown, indicating the need for further investigation.

Chiropractic management of a geriatric patient with idiopathic neuralgic amyotrophy: a case report.

OBJECTIVE: The purpose of this paper is to describe chiropractic management of a patient with neuralgic amyotrophy (NA) and to provide discussion regarding presentation, differential diagnosis, management and prognosis of idiopathic NA. CASE PRESENTATION: An 85 year old Caucasian male presented to a chiropractic clinic with right periscapular and lateral rib cage pain. The patient had previously sought evaluation and treatment from multiple health care providers and underwent multiple interventions without relief. INTERVENTION AND OUTCOME: The patient was managed with a course of chiropractic care and an ongoing home exercise program was carried out. The patient reported spontaneous resolution of pain approximately 14 months post onset. SUMMARY: NA is a poorly known clinical entity amongst health care providers and poses challenges in timely and proper diagnosis. Recognition of NA is important for patients to be best managed and for more optimal patient outcomes to be achieved.

OBJECTIF: Ce document a pour objectif de décrire la prise en charge chiropratique d'un patient atteint d'amyotrophie névralgique (AN), ainsi que de discuter de la présentation, du diagnostic différentiel, de la prise en charge et du pronostic d'AN idiopathique. EXPOSÉ DE CAS: Un homme blanc de 85 ans se présente à une clinique de chiropratique en se plaignant de douleur périscapulaire droite et latérale à la cage thoracique. Le patient s'était déjà fait évalué et traité par nombre de fournisseurs de soins de santé et avait subi de nombreuses interventions, sans soulagement. INTERVENTION ET RÉSULTAT: Le patient a reçu des soins chiropratiques et on lui a créé un programme d'exercices à domicile. Le patient a déclaré une disparition spontanée de la douleur environ quatorze mois après l'apparition des symptômes. RÉSUMÉ: L'AN est une entité clinique mal connue des fournisseurs de soins de santé, ce qui complique le fait de parvenir à un diagnostic exact avec rapidité. Il est important de reconnaître l'AN pour assurer une prise en charge optimale des patients et obtenir des résultats optimaux.
