Primary care referral of patients with low back pain to physical therapy: impact on future health care utilization and costs

Measuring guideline adherence in physiotherapy: A scoping review of methodological approaches

RATIONALE

Clinical practice guidelines summarise the existing evidence on specific health conditions and aim to optimise quality of care by providing evidence-based recommendations. Studies have reported a gap between research findings and clinical practice in physiotherapy. Guideline adherence is often used as a measure of agreement between therapeutic care and guideline recommendations. However, there is currently no standardised methodological approach for measuring guideline adherence.

AIMS AND OBJECTIVE

The objective of this scoping review was to summarise the methods and results of studies that assessed guideline adherence in physiotherapy.

METHODS

MEDLINE, EMBASE, PEDro and CENTRAL databases were searched for relevant literature up to December 2022. Published reports of observational studies and controlled clinical trials that provided information on the assessment of guideline adherence in physiotherapists were included. The selection process was performed independently by two reviewers. The methodological quality of the identified reports was not assessed. Results were summarised narratively.

RESULTS

From a total of 2560 potentially relevant records, 53 reports were included in the analysis. Physiotherapists' adherence to guidelines was primarily assessed in the context of musculoskeletal conditions, such as low back pain (n = 25, 47.2%) and osteoarthritis (n = 8, 15.1%). A wide range of measurement approaches were used with the majority of reports using web-based surveys (n = 21, 39.6%), followed by chart reviews (n = 17, 32.1%). Most reports (n = 21, 39.6%) provided information on the level of adherence in terms of frequency dichotomising (self-reported) clinical practice as adherent or non-adherent. Adherence rates varied widely between included reports.

CONCLUSIONS

Although the large number of included reports indicates a high level of interest in the topic of guideline adherence, there is considerable heterogeneity between studies regarding the methodological approaches used to assess guideline adherence in physiotherapists. This reduces the comparability of the study results.

Key Factors Driving Physiotherapy Use in Patients with Nonspecific Low Back Pain: Retrospective Clinical Data Analysis

Background/objectives: Understanding the factors that influence physiotherapy (PT) service use among patients with nonspecific lower back pain (LBP) is necessary to optimize treatment strategies, healthcare resource allocation, and the planning of value-based initiatives. We report factors that influence the number of PT visits per episode of care (defined as a referral from a physician) for an LBP population in Saudi Arabia, and compare them with patients experiencing their first and recurrent episodes of LBP. Methods: LBP patients were retrospectively enrolled from a clinical dataset derived from an outpatient PT clinic in Saudi Arabia. The primary outcome variable was the number of PT visits performed per episode of care. Multiple linear regression analysis was performed to examine the relationships between the numbers of PT visits per episode of care and independent variables. Results: The number of PT sessions per week (β 0.34, p < 0.001), compliance with PT sessions (β 0.31, p < 0.001), and pre-pain scores (β 0.29, p < 0.001) explained 41.8% (adjusted R2 0.32) of the variance in the total number of PT visits per episode of care (p < 0.001). Conclusions: Factors that might improve value-based care for LBP patients are reported. The more PT sessions per week, compliance with these sessions, and higher baseline pain scores predict a higher number of PT visits per episode of care among these patients. While reported for a Saudi Arabian population, there is no reason to believe that these findings do not apply internationally.

The Influence of Active, Passive, and Manual Therapy Interventions on Escalation of Health Care Events After Physical Therapist Care in Veterans With Low Back Pain

OBJECTIVE

The objective of this study was to examine the associations between active, passive, and manual therapy interventions with the escalation-of-care events following physical therapist care for veterans with low back pain (LBP).

METHODS

A retrospective cohort study was conducted in 3618 veterans who received physical therapist care for LBP between January 1, 2015 and January 1, 2018. The Department of Veterans Affairs (VA) Corporate Data Warehouse was utilized to identify LBP-related physical therapist visits and procedures, as well as opioid prescription and non-physical therapy clinic encounters. The association between physical therapist interventions with 1-year escalation-of-care events were assessed using adjusted odds ratios from logistic regression.

RESULTS

Nearly all veterans (98%) received active interventions, but only a minority (31%) received manual therapy. In the 1-year follow-up period, the odds of receiving an opioid prescription were 30% lower for those who received manual therapy in addition to active interventions, as compared with patients who received only active interventions. Moreover, the odds of receiving primary care, specialty care, and diagnostic testing were 30% to 130% higher for patients who received electrical stimulation or more than 1 passive intervention in addition to active treatments, as compared with patients who received only active interventions.

CONCLUSION

The use of manual therapy along with active interventions was associated with reduced prescription of opioids, while utilization of specific passive interventions such as electrical stimulation or multiple modalities in conjunction with active interventions resulted in increased escalation-of-care events.

IMPACT

The use of active interventions, which is supported by most clinical practice guidelines, was the cornerstone of physical therapist care for veterans with LBP. However, the use of clinical practice guideline-recommended manual therapy interventions was low but associated with reduced opioid prescriptions. The use of 2 or more different passive interventions along with active interventions was common (34%) and associated with less-than-optimal escalation-of-care outcomes.

Real-life implementation and evaluation of the e-referral system SIPILINK

INTRODUCTION

General Practitioners (GPs) play a key role of gatekeeper, as they coordinate patients' care. However, most of them reported having difficulty to refer patients to hospital, especially in semi-urgent context. To facilitate the referral of semi-urgent patients, we implemented an e-referral platform, named SIPILINK, within 4 wards from a large public French hospital (internal medicine, diabetology, gynaecological surgery and oncology wards). Here, we aimed to evaluate the SIPILINK e-referral platform after 2 years of implementation.

METHODS

The evaluation included a multidimensional assessment based on the RE-AIM framework with the analysis of implementation, requests, health professionals' satisfaction, and estimated hospital payment.

RESULTS

Over 2 years of implementation, GPs sent 113 requests to hospital. Hospital respected the time of response requested by GPs in 93 % of cases and proposed a consultation or hospitalization in respectively 40.7 % and 10.6 % of cases. 100 % of GPs and 78 % of Hospital Practitioners (HPs) were satisfied with the quality of exchanges. 77 % of HPs and 100 % of Care Pathway Managers (CPMs) found that patient care pathways were improved. Nearly all practitioners would recommend this platform for patient referrals.

DISCUSSION

SIPILINK shows promise in streamlining the referral process, enhancing communication, and improving patient care pathways. Further studies including the impact on the quality of care, are needed to assess its effectiveness and sustainability in healthcare settings.

The Association of Physiotherapy and Opioid Use With Duration of Compensated Time Loss for Workers With Low Back Pain

OBJECTIVE

To determine patterns of physiotherapy and opioid use among compensated workers with low back pain (LBP), factors associated with these, and their association with time loss.

METHODS

Accepted Victorian and South Australian workers' compensation claims, services, and medicines data for LBP claims lodged June 30, 2010-July 1, 2015. Descriptive statistics, multinomial logistic, and Cox regression were used to determine usage groups, their predictors, and effect of these on time loss.

RESULTS

Of 15,728 claims, 24.4% received no services, 3.6% received opioids only, 43.3% received physiotherapy only, and 28.8% received both opioids and physiotherapy. Sex, age, occupation, remoteness, jurisdiction, and socioeconomic status were significantly associated with usage groups. Using opioids and physiotherapy had the longest time loss.

CONCLUSIONS

Any services/medicine usage was associated with increased time loss and was longest for combined physiotherapy and opioids.

Utilization of Reimbursed Acupuncture Therapy for Low Back Pain

Importance

Treating low back pain (LBP) often involves a combination of pharmacologic, nonpharmacologic, and interventional treatments; one approach is acupuncture therapy, which is safe, effective, and cost-effective. How acupuncture is used within pain care regimens for LBP has not been widely studied.

Objective

To document trends in reimbursed acupuncture between 2010 and 2019 among a large sample of patients with LBP, focusing on demographic, socioeconomic, and clinical characteristics associated with acupuncture use and the nonpharmacologic, pharmacologic, and interventional treatments used by patients who utilize acupuncture.

Design, Setting, and Participants

This cross-sectional study included insurance claims of US adults in a deidentified database. The study sample included patients diagnosed with LBP between 2010 and 2019. Data were analyzed between September 2023 and June 2024.

Main Outcomes and Measures

Changes in rates of reimbursed acupuncture utilization between 2010 and 2019, including electroacupuncture use, which involves the electrical stimulation of acupuncture needles. Covariates included age, sex, race and ethnicity, income, educational attainment, region, and a chronic LBP indicator. Secondary analyses tracked other nonpharmacologic treatments (eg, physical therapy, chiropractic care), pharmacologic treatments (eg, opioids, gabapentinoids), and interventional treatments (eg, epidural steroid injections).

Results

The total sample included 6 840 497 adults with LBP (mean [SD] age, 54.6 [17.8] years; 3 916 766 female [57.3%]; 802 579 Hispanic [11.7%], 258 087 non-Hispanic Asian [3.8%], 804 975 non-Hispanic Black [11.8%], 4 974 856 non-Hispanic White [72.7%]). Overall, 106 485 (1.6%) had 1 or more acupuncture claim, while 61 503 (0.9%) had 1 or more electroacupuncture claim. The rate of acupuncture utilization increased consistently, from 0.9% in 2010 to 1.6% in 2019; electroacupuncture rates were relatively stable. Patients who were female (male: odds ratio [OR], 0.68; 99% CI, 0.67-0.70), Asian (OR, 3.26; 99% CI, 3.18-3.35), residing in the Pacific region (New England: OR, 0.26; 99% CI, 0.25-0.28), earning incomes of over $100 000 (incomes less than $40 000: OR, 0.59; 99% CI, 0.57-0.61), college educated (high school or less: OR, 0.32; 99% CI, 0.27-0.35), and with chronic LBP (OR, 2.39; 99% CI, 2.35-2.43) were more likely to utilize acupuncture. Acupuncture users were more likely to engage in other nonpharmacologic pain care like physical therapy (39.2%; 99% CI, 38.9%-39.5% vs 29.3%; 99% CI, 29.3%-29.3%) and less likely to utilize prescription drugs, including opioids (41.4%; 99% CI, 41.1%-41.8% vs 52.5%; 99% CI, 52.4%-52.5%), compared with nonusers.

Conclusions and Relevance

In this cross-sectional study, we found that acupuncture utilization among patients with LBP was rare but increased over time. Demographic, socioeconomic, and clinical characteristics were associated with acupuncture utilization, and acupuncture users were more likely to utilize other nonpharmacologic treatments and less likely to utilize pharmacologic treatments.

Dietary supplementation with plant extracts for amelioration of persistent myofascial discomfort in the cervical and back regions: a randomized double-blind controlled study

Background

Back pain is a common health problem that affects both workers and older people, reducing their quality of life. The primary objective was to assess the effect of dietary supplementation with plant extracts of rosemary, ashwagandha, and sesame consumed for 12 weeks on the intensity of back pain.

Methods

A single-center randomized double-blind study with three parallel arms depending on the product consumed. The duration of treatment was 12 weeks. The investigational product, Berelief®, contained a blend of three polyphenolic standardized extracts: rosemary (Rosmarinus officinalis L.), ashwagandha (Withania somnifera L.), and sesame (Sesamum indicum L.) seed. Two doses were tested: low dose (400 mg) and high dose (800 mg). There were 42 subjects in the placebo group, 39 in the low dose and 42 in the high dose groups. Study variables included back pain intensity [VAS score, Patient-Reported Outcomes Measurement Information System (PROMIS-29), and Cornell Musculoskeletal Discomfort Questionnaire; functionality Roland-Morris Disability (RMD) questionnaire]; quality of life (QoL) [36-item Short Form Survey (SF-36), the Beck Depression Inventory-II (BDI-II), the State-Trait Anxiety Inventory (STAI), and the Perceived Stress Scale (PSS)]; sleep quality [accelerometer and Pittsburgh Sleep Quality Index (PSQI)].

Results

The improvement in back pain recorded by the visual analogue scale (VAS) at the study visits after the beginning of treatment, as well as on a weekly basis recorded in the diary card was significantly higher in the intervention group than in the placebo group (p < 0.044 dose-low; p < 0.005 dose-high). Significant differences in pain intensity of the PROMIS-29 (p = 0.002) and upper back pain in the Cornell questionnaire (p = 0.011) in favour of the investigational product were found. Furthermore, benefits in improving health-related quality of life, mood and sleep quality were also detected.

Conclusion

Dietary supplementation for 12 weeks of a blend of polyphenolic standardized extracts of rosemary, ashwagandha, and sesame was effective in reducing the intensity of pain in subjects with chronic myofascial cervical and back pain.

Differential screen and treatment of sternocleidomastoid syndrome versus eagle syndrome: a case report

BACKGROUND/PURPOSE

Differential screening is a complex process in chronic pain conditions. There is significant uncertainty that surrounds the pathophysiology of many chronic pain syndromes that may lead to misdiagnosis and treatment failures. Such differential screening is even more challenging where there is regional overlapping from surrounding tissues. This case report chronicles the differential screening and treatment of a patient with sternocleidomastoid syndrome (SCMS) originally diagnosed as Eagle's syndrome (ES).

CASE DESCRIPTION

A 55-year-old woman, referred to a physical therapist (PT) by an ear, nose and throat (ENT) physician with the diagnosis of ES. The patient complained of yearlong left-sided otalgia, blurred vision, excessive lacrimation, dysphagia, hyperesthesia on the left side of the face, unilateral temporal headaches, and both left mandibular and anterior neck pain.

OUTCOMES

The PT examination revealed the patient did not exhibit hallmark findings for clinical confirmation of ES and instead demonstrated multiple signs consistent with SCMS.

DISCUSSION

Manual therapy techniques and therapeutic exercises resolved the patient's year-long chronic symptoms within 6 sessions.

A Rapid Review of Interventions to Improve Care for People Who Are Medically Underserved with Multiple Sclerosis, Diabetic Retinopathy, and Lung Cancer

In the United States, patients with chronic conditions experience disparities in health outcomes across the care continuum. Among patients with multiple sclerosis, diabetic retinopathy, and lung cancer, there is a lack of evidence summarizing interventions to improve care and decrease these disparities. The aim of this rapid literature review was to identify interventions among patients with these chronic conditions to improve health and reduce disparities in screening, diagnosis, access to treatment and specialists, adherence, and retention in care. Using structured search terms in PubMed and Web of Science, we completed a rapid review of studies published in the prior five years conducted in the United States on our subject of focus. We screened the retrieved articles for inclusion and extracted data using a standard spreadsheet. The data were synthesized across clinical conditions and summarized. Screening was the most common point in the care continuum with documented interventions. Most studies we identified addressed interventions for patients with lung cancer, with half as many studies identified for patients with diabetic retinopathy, and few studies identified for patients with multiple sclerosis. Almost two-thirds of the studies focused on patients who identify as Black, Indigenous, or people of color. Interventions with evidence evaluating implementation in multiple conditions included telemedicine, mobile clinics, and insurance subsidies, or expansion. Despite documented disparities and a focus on health equity, a paucity of evidence exists on interventions that improve health outcomes among patients who are medically underserved with multiple sclerosis, diabetic retinopathy, and lung cancer.

Financial impact associated with implementation of the low back pain clinical practice guideline in outpatient physical therapist practice at a large academic medical center

INTRODUCTION

Low back pain (LBP) is the top health condition requiring rehabilitation in the United States. The financial burden of managing LBP is also amongst the highest in the United States. Clinical practice guidelines (CPGs) provide management recommendations and have the potential to lower health costs. Limited evidence exists on the impact of CPG implementation on downstream medical costs.

OBJECTIVE

To examine the impact of CPG implementation in physical therapist (PT) practice on direct and downstream costs for patients with LBP.

METHODS

A retrospective observational study examined billing data from 270 patients with LBP who were treated at multiple sites within one large academic medical center by PTs who participated in a multifaceted CPG implementation program. Costs were analyzed for direct PT services, downstream medical services, and PT utilization from September 2017 to March 2018 (pre-implementation group) and compared with costs from June 2018 to December 2018 (post-implementation group).

RESULTS

Direct PT costs were significantly lower post-implementation than pre-implementation mean: $2,863 USD (SD: $1,968) vs. $3,459 USD (SD: $2,838), p = .05, 95% CI [11, 1182]. All downstream costs were lower post-implementation with statistically significant lower costs found in downstream imaging: p = .04, 95% CI [32, 1,905]; pharmacy: p = .03, 95% CI [70, 1,217]; surgery: p = .03, 95% CI [446, 9,152], and "other": p = .02, 95% CI [627, 7,920].

CONCLUSION

Implementing the LBP CPG in outpatient PT practice can have a positive impact on lowering downstream costs and the potential to increase the value of PT services.

Association between physiotherapy utilization and medical healthcare utilization and costs in adults with back pain from Ontario, Canada: a population-based cohort study

ABSTRACT

This study examined the association between physiotherapy utilization and subsequent medical healthcare utilization and costs in a population-based sample of adults with back pain in Ontario. We conducted a population-based cohort study of Ontario respondents with back pain (≥18 years) of the Canadian Community Health Survey 2003 to 2010 cycles, linked to health administrative data up to 2018. Physiotherapy utilization was defined as self-reported consultation with a physiotherapist in the past 12 months. A propensity score-matched cohort was conducted to match adults with and without physiotherapy utilization, accounting for potential confounders. We assessed associations using negative-binomial and linear (log-transformed) regression to evaluate outcomes of healthcare utilization (back pain-specific and all-cause) and costs, respectively, at 1- and 5-year follow-up. There were 4343 pairs of matched respondents. Compared with those who did not receive physiotherapy, adults who received physiotherapy were more likely to have back pain-specific physician visits (RR women (5years) = 1.48, 95% CI 1.24-1.75; RR men (5years) = 1.42, 95% CI 1.10-1.84). Women who received physiotherapy had 1.11 times the rate of all-cause physician visits (RR 1year = 1.11, 95% CI 1.02-1.20), and men who received physiotherapy had 0.84 times the rate of all-cause hospitalizations (RR 5years = 0.84, 95% CI 0.71-0.99) than those who did not. There was no association between physiotherapy utilization and healthcare costs. Adults with back pain who received physiotherapy are more likely to have back pain-specific physician visits up to 5-year follow-up than those who did not. Physiotherapy utilization is linked to some sex-based differences in all-cause healthcare utilization but not differences in costs. Findings inform interprofessional collaboration and allied healthcare delivery for back pain in Ontario.

On the geographic access to healthcare, beyond proximity

This study examined the incongruence of travel distance between the nearest provider and the provider that pregnant woman actually chose to visit. Using a dataset of South Carolina claims including rural and urban areas for the period 2014-2018 based on live births of 27,290 pregnant women, we compared the travel distance and travel time for two providers of health: the nearest facility and the main one for the area in question. The number of the former type was counted for every case. The mean travel distance/time to the nearest provider was 3.2 miles (5.2 km) and 5.0 minutes, while that to the main (predominant) provider was 23.0 miles (37.0 km) and 31.7 minutes. Only 21.6% of pregnant women chose one of the closest facilities as their provider. The mean travel distance and time to the nearest provider for women in rural areas were more than twice that for urban women but only 1.2 times for the main provider. Rural women had one third fewer providers situated closer than the main in comparison to number available for urban women. Thus, we conclude that proximity is not the only factor associated with access to healthcare. While evaluating geographic access, the number of available health providers within the mean travel distance or time would be a better indicator of proximate access.

Integration of primary contact physiotherapists in the emergency department for individuals presenting with minor musculoskeletal disorders: Protocol for an economic evaluation

OBJECTIVES

1) To compare the average cost of an emergency department (ED) visit for various minor musculoskeletal disorders between two models of care (physiotherapist and ED physician or ED physician alone); 2) To evaluate the incremental cost-effectiveness ratio (ICER) of these two models of care over a 3-month period post-initial visit; and 3) To estimate the ICER of three ED models of care (physiotherapist and ED physician, ED physician alone, physiotherapist alone) over a two-year period.

METHODS

Obj.1: The costs incurred by participants in the two groups during their ED visit will be calculated using the Time-Driven Activity-Based Costing (TDABC) method. These costs will be compared using generalized linear models. Obj. 2: The ICER of the two models will be evaluated over three months via a cost-utility analysis that will combine costs and effectiveness data (quality-adjusted life years) using both Health system and Societal perspectives (patient + health system costs). Obj. 3: The 2-year ICER of the three above-mentioned models will be estimated using a mathematical model including a decision tree (0-3 months post-visit) and a Markov model (3-24 months post-visit), also using both Health system and Societal perspectives. Data to answer the three objectives will come from data collected during a randomized clinical trial (n = 78, CHU de Québec)which will be supplemented with data obtained via some of the CHU de Québec administrative databases (nominative data; SIURGE (ED management software), Cristal-Net (patient electronic record), and the ED's pharmacy transactions directory; administrative data: drug costs repository), the literature, and public cost repositories.

CONCLUSION

This study will help to determine which model of care is most efficient for the management of individuals who come to the ED with minor musculoskeletal disorders. The increased involvement of various health professionals in the management of patients in the ED paves the way for the development of new avenues of practice and more efficient organization of services.

Racial and Ethnic Differences in Receipt of Nonpharmacologic Care for Chronic Low Back Pain Among Medicare Beneficiaries With OUD

Importance

Nonpharmacologic treatments are important for managing chronic pain among persons with opioid use disorder (OUD), for whom opioid and other pharmacologic therapies may be particularly harmful. Racial and ethnic minority individuals with chronic pain and OUD are vulnerable to suboptimal pain management due to systemic inequities and structural racism, highlighting the need to understand their receipt of guideline-recommended nonpharmacologic pain therapies, including physical therapy (PT) and chiropractic care.

Objective

To assess differences across racial and ethnic groups in receipt of PT or chiropractic care for chronic low back pain (CLBP) among persons with comorbid OUD.

Design, Setting, and Participants

This retrospective cohort study used a 20% random sample of national Medicare administrative data from January 1, 2016, to December 31, 2018, to identify fee-for-service community-dwelling beneficiaries with a new episode of CLBP and comorbid OUD. Data were analyzed from March 1, 2022, to July 30, 2023.

Exposures

Race and ethnicity as a social construct, categorized as American Indian or Alaska Native, Asian or Pacific Islander, Black or African American, Hispanic, non-Hispanic White, and unknown or other.

Main Outcomes and Measures

The main outcomes were receipt of PT or chiropractic care within 3 months of CLBP diagnosis. The time (in days) to receiving these treatments was also assessed.

Results

Among 69 362 Medicare beneficiaries analyzed, the median age was 60.0 years (IQR, 51.5-68.7 years) and 42 042 (60.6%) were female. A total of 745 beneficiaries (1.1%) were American Indian or Alaska Native; 444 (0.6%), Asian or Pacific Islander; 9822 (14.2%), Black or African American; 4124 (5.9%), Hispanic; 53 377 (77.0%); non-Hispanic White; and 850 (1.2%), other or unknown race. Of all beneficiaries, 7104 (10.2%) received any PT or chiropractic care 3 months after a new CLBP episode. After adjustment, Black or African American (adjusted odds ratio, 0.46; 95% CI, 0.39-0.55) and Hispanic (adjusted odds ratio, 0.54; 95% CI, 0.43-0.67) persons had lower odds of receiving chiropractic care within 3 months of CLBP diagnosis compared with non-Hispanic White persons. Median time to chiropractic care was longest for American Indian or Alaska Native (median, 8.5 days [IQR, 0-44.0 days]) and Black or African American (median, 7.0 days [IQR, 0-42.0 days]) persons and shortest for Asian or Pacific Islander persons (median, 0 days [IQR, 0-6.0 days]). No significant racial and ethnic differences were observed for PT.

Conclusions and Relevance

In this retrospective cohort study of Medicare beneficiaries with comorbid CLBP and OUD, receipt of PT and chiropractic care was low overall and lower across most racial and ethnic minority groups compared with non-Hispanic White persons. The findings underscore the need to address inequities in guideline-concordant pain management, particularly among Black or African American and Hispanic persons with OUD.

First Provider Seen for an Acute Episode of Low Back Pain Influences Subsequent Health Care Utilization

OBJECTIVE

Costs associated with low back pain (LBP) continue to rise. Despite numerous clinical practice guidelines, the evaluation and treatments for LBP are variable and largely depend on the individual provider. As yet, little attention has been given to the first choice of provider. Early research indicates that the choice of first provider and the timing of interventions for LBP appear to influence utilization. We sought to examine the association between the first provider seen and health care utilization.

METHODS

Using 2015-2018 data from a large insurer, this retrospective analysis focused on patients (29,806) seeking care for a new episode of LBP. The study identified the first provider chosen and examined the following year of medical utilization. Cox proportional hazards models were calculated using inverse probability weighting on propensity scores to evaluate the time to event and the relationship to the first choice of provider.

RESULTS

The primary outcome was the timing and use of health care resources. Total health care use was lowest in those who first sought care with chiropractic care or physical therapy. Highest health care use was seen in those patients who chose the emergency department.

CONCLUSION

Overall, there appears to be an association between the first choice of provider and future health care use. Chiropractic care and physical therapy provide nonpharmacologic and nonsurgical, guideline-based interventions. The use of physical therapists and chiropractors as entry points into the health system appears related to a decrease in immediate and long-term use of health resources. This study expands the existing body of literature and provides a compelling case for the influence of the first provider on an acute episode of LBP.

IMPACT

The first provider seen for an acute episode of LBP influences immediate treatment decisions, the trajectory of a specific patient episode, and future health care choices in the management of LBP.

The care pathway of individuals with spinal disorders in a Health Care Network in the Federal District, Brazil: a retrospective study

BACKGROUND

Understanding the care pathway is essential to identify how to effectively treat spinal disorders. However, there is no specific data on the pathway of these individuals in the Health Care Networks (HCN) in Brazil.

OBJECTIVE

To investigate the pathway of individuals with non-specific spinal disorders (NSD) in the HCN in the Federal District, Brazil, and verify the interventions adopted, and to test whether sociodemographic and clinical variables predict the number of imaging tests, prescribed medication, and the first HCN access.

METHODS

Retrospective study that analysed electronic records of 327 individuals with NSD between 2012 and 2018. Generalized linear models estimated the association between sociodemographic and clinical data and number of drugs prescribed and imaging tests requested. Multinomial logistic regression estimated the association between clinical and demographic variables and setting of first access.

RESULTS

The median age was 57 years, and 75.5% were women. Emergency Department (ED) was the most accessed setting (43.7%), and back pain was the most prevalent condition (84.5%). Most individuals underwent imaging tests (60%) and drug prescriptions (86%). Physical exercises were prescribed to 13%, and 55% were referred to physical therapy. Women were more likely to first access the ED.

CONCLUSION

The ED was the most used setting by people with NSD. Few participants received exercise prescriptions and half were referred to physical therapists. Individuals who used outpatient clinics and primary care received less drug prescriptions, and women were more likely to first access the ED. Increasing age was associated with greater chance of first accessing Outpatient Clinics.

Significant Clinical Improvement Was Predicted in a Cohort of Patients With Low Back Pain Early in the Care Process

OBJECTIVE

The purpose of this study was to determine the proportion of patients with low back pain who achieved clinical improvement in disability within 3 or 6 physical therapy visits, identify factors that predicted improvement, and predict the probability of improvement by the third and sixth visits.

METHODS

This retrospective, observational study looked at patients (N = 6523) who completed a numeric pain scale and Modified Low Back Disability Questionnaire (MDQ) at every visit. Four prediction models were developed: 30% improvement by visit 3 and by visit 6 and 50% improvement by visit 3 and by visit 6. A logistic regression model was fit to predict patients' improvement in disability using the MDQ. Predictive models used age, disability scores, sex, symptom duration, and payer type as factors. Receiver operating characteristic curves and area under the curve were computed for the models. Nomograms illustrate the relative impacts of the predictor variables.

RESULTS

Disability improved 30% in 42.7% of patients by visit 3 and 49% by visit 6. Disability improved 50% in 26% of patients by visit 3 and 32.9% by visit 6. First visit score (MDQ1) was strongest factor to predict 30% improvement by visit 3. The visit 3 score (MDQ3) was strongest factor to predict a 30% or 50% improvement by visit 6. The combination of MDQ1 and MDQ3 scores was strongest overall predictive factor for visit 6. The area under the curve values for models using only the MDQ1 and MDQ3 scores to predict 30% or 50% improvement by the sixth visit were 0.84 and 0.85, respectively, representing excellent overall diagnostic accuracy of the prediction models.

CONCLUSION

Excellent discrimination to predict patients' significant clinical improvement by visit 6 using 2 outcome scores was demonstrated. Gathering outcomes routinely enhances assessment of prognosis and clinical decision making.

IMPACT

Understanding prognosis of clinical improvement supports physical therapists' contribution to value-based care.

Delayed timing of physical therapy initiation increases the risk of future opioid use in individuals with knee osteoarthritis: a real-world cohort study

OBJECTIVE

We assessed whether late versus early initiation of physical therapy (PT) was related to greater risk of future opioid use in people with knee osteoarthritis (OA) who receive PT.

METHODS

We used Commercial and Medicare Advantage claims data from 1999 to 2018 from American adults with incident knee OA referred for PT within 1 year of diagnosis. We categorised people as opioid naïve or opioid experienced based on prior prescriptions. We examined the association of timing of PT initiation with any and chronic opioid use over 1 year.

RESULTS

Of the 67 245 individuals with incident knee OA, 35 899 were opioid naïve and 31 346 were opioid experienced. In the opioid naïve group, compared with PT within 1 month, PT 1 to <3, 3 to <6, 6 to <9, 9-12 months from diagnosis was associated with adjusted risk ratio (aRR (95% CIs)) for any opioid use of 1.18 (1.10 to 1.28), 1.49 (1.37 to 1.61), 1.73 (1.58 to 1.89) and 1.93 (1.76 to 2.12), respectively; aRRs (95% CIs) for chronic opioid use were 1.25 (1.01 to 1.54), 1.83 (1.48 to 2.26), 2.29 (1.82 to 2.89) and 2.50 (1.96 to 3.19). Results were similar among opioid experienced; aRRs (95% CIs) for any opioid use were 1.19 (1.14 to 1.24), 1.32 (1.26 to 1.37), 1.39 (1.32 to 1.45) and 1.54 (1.46 to 1.61); aRRs (95% CIs) for chronic opioid use were 1.25 (1.17 to1.34), 1.43 (1.33 to 1.54), 1.53 (1.41 to 1.66) and 1.65 (1.51 to 1.80).

CONCLUSION

Compared with PT initiation within 1 month, delayed PT initiation was associated with higher risk of opioid use in people with incident knee OA. The longer the delay in PT initiation, the greater was the risk.

Investigation of the Relevant Factors in the Complexity of Chronic Low Back Pain Patients With a Physiotherapy Prescription: A Network Analysis Approach Comparing Chronic Pain-Free Individuals and Chronic Patients

OBJECTIVE

Chronic low back pain (CLBP) is the leading cause of disability worldwide, and several factors have been proposed as potential causes or cofactors. The aim of this study was to explore their direct and indirect relations to understand CLBP and identify relevant rehabilitation targets.

METHODS

A total of 119 patients with CLBP and 117 chronic pain-free individuals were assessed. A network analysis approach was used to explore the complexity of CLBP by assessing the relations between pain intensity, disability, functionality (physical, social, and psychological), age, body mass index, and education level.

RESULTS

The network analysis revealed the independence of pain and disability related to CLBP from age, sex, and body mass index. Crucially, pain intensity and disability are directly and strongly connected in chronic pain-free individuals, but not in patients with CLBP. Psychosocial functioning is related to pain intensity and disability indirectly through the mediation of one's general health perception and perceived physical functionality.

CONCLUSION

Clinicians should pay more attention to perceived physical functionality and psychosocial factors as they are tightly linked to CLBP. Indeed, pain intensity seems a suboptimal rehabilitation target. This study suggests that a biopsychosocial approach is much needed to investigate CLBP, but it also warns against overestimating the direct impact of each potential contributor.

Global and regional estimates of clinical and economic burden of low back pain in high-income countries: a systematic review and meta-analysis

Introduction

Low back pain (LBP) is a common health problem, and the leading cause of activity limitation and work absence among people of all ages and socioeconomic strata. This study aimed to analyse the clinical and economic burden of LBP in high income countries (HICs) via systematic review and meta-analysis.

Methods

A literature search was carried out on PubMed, Medline, CINAHL, PsycINFO, AMED, and Scopus databases was from inception to March 15th, 2023. Studies that assessed the clinical and economic burden of LBP in HICs and published in English language were reviewed. The methodological quality of the included studies was assessed using the Newcastle-Ottawa quality assessment scale (NOS) for cohort studies. Two reviewers, using a predefined data extraction form, independently extracted data. Meta-analyses were conducted for clinical and economic outcomes.

Results

The search identified 4,081 potentially relevant articles. Twenty-one studies that met the eligibility criteria were included and reviewed in this systematic review and meta-analysis. The included studies were from the regions of America (n = 5); Europe (n = 12), and the Western Pacific (n = 4). The average annual direct and indirect costs estimate per population for LBP ranged from € 2.3 billion to € 2.6 billion; and € 0.24 billion to $8.15 billion, respectively. In the random effects meta-analysis, the pooled annual rate of hospitalization for LBP was 3.2% (95% confidence interval 0.6%-5.7%). The pooled direct costs and total costs of LBP per patients were USD 9,231 (95% confidence interval -7,126.71-25,588.9) and USD 10,143.1 (95% confidence interval 6,083.59-14,202.6), respectively.

Discussion

Low back pain led to high clinical and economic burden in HICs that varied significantly across the geographical contexts. The results of our analysis can be used by clinicians, and policymakers to better allocate resources for prevention and management strategies for LBP to improve health outcomes and reduce the substantial burden associated with the condition.

Financial Impact of Embedded Injury-Prevention Experts in US Army Initial Entry Training

CONTEXT

The US Army embedded injury-prevention experts (IPEs), specifically athletic trainers and strength and conditioning coaches, into initial entry training (IET) to limit musculoskeletal (MSK) conditions and their negative consequences. However, little is known about the financial impact of IPEs.

OBJECTIVE

To assess whether IPEs were associated with fewer sunk training costs due to MSK-related early discharges from service.

DESIGN

Retrospective cohort study.

SETTING

Database of US Army soldiers' administrative, medical, and readiness records.

PATIENTS OR OTHER PARTICIPANTS

A total of 198 166 soldiers (age = 20.7 ± 3.2 years, body mass index = 24.4 ± 3.5 kg/m2) who began IET during 2014 to 2017.

MAIN OUTCOME MEASURE(S)

Early discharge from service was defined as occurring within 6 months of beginning IET. All IET sites employed IPEs from 2011 to 2017, except for 2 sites during April to November 2015. Soldiers who began IET at these 2 sites during these times were categorized as not having IPE exposure. All others were categorized as having IPE exposure. The unadjusted association between IPE access and MSK-related early discharge from service was assessed using logistic regression. Financial impact was assessed by quantifying differences in yearly sunk costs between groups with and those without IPE exposure and subtracting IPE hiring costs.

RESULTS

Among 14 094 soldiers without IPE exposure, 2.77% were discharged early for MSK-related reasons. Among 184 072 soldiers with IPE exposure, 1.01% were discharged. Exposure to IPEs was associated with reduced odds of MSK-related early discharge (odds ratio = 0.36, 95% CI = 0.32, 0.40, P < .001) and a decrease in yearly sunk training costs of $11.19 to $20.00 million.

CONCLUSIONS

Employing IPEs was associated with reduced sunk costs because of fewer soldiers being discharged from service early for MSK-related reasons. Evidence-based recommendations should be developed for guiding policy on the roles and responsibilities of IPEs in the military to reduce negative outcomes from MSK conditions and generate a positive return on investment.

Initial treatment approaches and healthcare utilization among veterans with low back pain: a propensity score analysis

BACKGROUND

Opioid prescriptions for Veterans with low back pain (LBP) persist despite the availability of PT, a lower medical risk treatment option. Patterns of treatment and subsequent healthcare utilization for Veterans with LBP are unknown. The purpose of this study was to evaluate the association of physical therapy (PT) and opioids and outcomes of spinal surgery and chronic opioid use for Veterans with incident LBP.

METHODS

We conducted a retrospective cohort study identifying Veterans with a new diagnosis of LBP using ICD codes from the Veterans Administration national database from 2012 to 2017. Veterans were classified into three treatment groups based on the first treatment received within 30 days of incident LBP: receipt of PT, opioids, or neither PT nor opioids. Outcomes, events of spinal surgery and chronic opioid use, were identified beginning on day 31 up to one year following initial treatment. We used propensity score matching to account for the potential selection bias in evaluating the associations between initial treatment and outcomes.

RESULTS

There were 373,717 incident cases of LBP between 2012 and 2017. Of those 28,850 (7.7%) received PT, 48,978 (13.1%) received opioids, and 295,889 (79.2%) received neither PT or opioids. Pain, marital status and the presence of cardiovascular, pulmonary, or metabolic chronic conditions had the strongest statistically significant differences between treatment groups. Veterans receiving opioids compared to no treatment had higher odds of having a spinal surgery (2.04, 99% CI: 1.67, 2.49) and progressing to chronic opioid use (11.8, 99% CI: 11.3, 12.3). Compared to Veterans receiving PT those receiving opioids had higher odds (1.69, 99% CI: 1.21, 2.37) of having spinal surgery and progressing to chronic opioid use (17.8, 99% CI: 16.0, 19.9).

CONCLUSION

Initiating treatment with opioids compared to PT was associated with higher odds of spinal surgery and chronic opioid use for Veterans with incident LBP. More Veterans received opioids compared to PT as an initial treatment for incident LBP. Our findings can inform rehabilitation care practices for Veterans with incident LBP.

Advanced practice physiotherapy care in emergency departments for patients with musculoskeletal disorders: a pragmatic cluster randomized controlled trial and cost analysis

BACKGROUND

Advanced practice physiotherapy (APP) models of care where physiotherapists are primary contact emergency department (ED) providers are promising models of care to improve access, alleviate physicians' burden, and offer efficient centered patient care for patients with minor musculoskeletal disorders (MSKD).

OBJECTIVES

To compare the effectiveness of an advanced practice physiotherapist (APPT)-led model of care with usual ED physician care for persons presenting with a minor MSKD, in terms of patient-related outcomes, health care resources utilization, and health care costs.

METHODS

This trial is a multicenter stepped-wedge cluster randomized controlled trial (RCT) with a cost analysis. Six Canadian EDs (clusters) will be randomized to a treatment sequence where patients will either be managed by an ED APPT or receive usual ED physician care. Seven hundred forty-four adults with a minor MSKD will be recruited. The main outcome measure will be the Brief Pain Inventory Questionnaire. Secondary measures will include validated self-reported disability questionnaires, the EQ-5D-5L, and other health care utilization outcomes such as prescription of imaging tests and medication. Adverse events and re-visits to the ED for the same complaint will also be monitored. Health care costs will be measured from the perspective of the public health care system using time-driven activity-based costing. Outcomes will be collected at inclusion, at ED discharge, and at 4, 12, and 26 weeks following the initial ED visit. Per-protocol and intention-to-treat analyses will be performed using linear mixed models with a random effect for cluster and fixed effect for time.

DISCUSSION

MSKD have a significant impact on health care systems. By providing innovative efficient pathways to access care, APP models of care could help relieve pressure in EDs while providing efficient care for adults with MSKD.

Patient attitudes and beliefs associated with self-referral to physical therapy for musculoskeletal complaints: a qualitative study

BACKGROUND

Non-pharmacologic treatments such as physical therapy (PT) are advocated for musculoskeletal pain. Early access to PT through self-referral has been shown to decrease costs and improve outcomes. Although self-referral is permitted in most U.S. states and supported by some health insurance plans, patients' utilization of self-referral remains low.

OBJECTIVE

To identify factors, beyond legislative policies and health insurance, associated with patients' decisions to access physical therapy through self-referral or provider-referral.

METHODS

We recruited 26 females and 6 males whose employer-sponsored insurance benefits included financial incentives for self-referral to physical therapy. Between August 2017 and March 2018, participants completed semi-structured interviews about their beliefs about physical therapy and reasons for choosing self-referral (15 participants) or provider referral (17 participants) for accessing physical therapy. Grounded theory approach was employed to identify themes in the data.

RESULTS

Patients selecting self-referral reported major thematic differences compared to the provider-referral patients including knowledge of the direct access program, attitudes and beliefs about physical therapy and pharmacologic treatment, and prior experiences with physical therapy. Self-referral patients were aware that their plan benefits included reduced cost for self-referral and felt confident in selecting that pathway. They also had negative beliefs about the effectiveness of pharmacological treatments and surgery, and previously had positive direct or indirect experiences with physical therapy.

CONCLUSION

Knowledge of the ability to self-refer, attitudes and beliefs about treatment, and prior experience with physical therapy were associated with self-referral to physical therapy. Interventions aimed at improving knowledge and changing attitudes toward self-referral to physical therapy to increase utilization appear warranted.

Factors associated with referral to physiotherapists for adult patients consulting for musculoskeletal disorders in primary care; an ancillary study to ECOGEN

BACKGROUND

Musculoskeletal disorders (MSD) are multifactorial requiring multidisciplinary treatment including physiotherapy. General practitioners (GP) have a central role in managing MSDs and mostly solicit physiotherapists accounting for 76.1% of physiotherapy referrals in France. Patient, physician, and contextual factors, including healthcare accessibility, can influence physiotherapy referral rates.

OBJECTIVE

To identify patient, physician, and contextual factors associated with physiotherapy referral in adult patients with MSDs in general practice.

METHODS

This study is based on the 2011/2012 French cross-sectional ECOGEN study. Analyses included working-age patients consulting their GP for any MSD. Physiotherapy referral was assessed initially, then adjusted multilevel logistic model analysis of patient, physician, geographical area-related factors associated with these referrals was performed.

RESULTS

Among the 2305 patients included, 456 (19.8%) were referred to a physiotherapist. Following multilevel multivariate analyses, physiotherapist referral was more frequent for female patients (OR 1.28; 95% CI [1.03, 1.59]) with spinal (OR 1.47; 95% CI [1.18, 1.83]) and upper limb disorders (OR 1.66; 95% CI [1.20, 2.29]), and less frequent for patients ≥ 50 years (OR 0.69; 95% CI [0.52, 0.91]), living in deprived geographical areas (OR 0.60; 95% CI [0.40, 0.90]). GPs referred to a physiotherapist less frequently if they were ≥ 50 years (OR 0.50; 95% CI [0.39, 0.63]), had a high number of annual consultations, or were practicing in semi-urban area in a multidisciplinary team.

CONCLUSION

This multilevel analysis identifies factors associated with physiotherapy referral for patients with MSDs, including living in deprived geographical areas. This constitutes an original contribution towards addressing healthcare disparities.

Patient perspectives of care pathways for people with low back pain: A qualitative study

BACKGROUND

Low back pain (LBP) care pathways aim to enhance health outcomes through patient-clinician mutual decision-making and care coordination. However, challenges to successful translation into practice include patients' understanding, expectation, and acceptance of treatment and management strategies for LBP. This study explored patients' perspectives and/or experience of care pathways and their involvement in decision-making in primary care.

METHODS

A qualitative descriptive design was adopted. Semi-structured interviews were conducted with 14 participants with LBP recruited from the community. Inductive thematic analysis of the qualitative data was conducted within the design framework to enable a systematic comparison of experiences across participants and within individual cases.

RESULTS

Five themes described participant perspectives and understanding of care pathways: i) care pathways can guide decision-making; ii) familiarity with no and/or stepped care pathway, but preference for matched or blend of care pathways; iii) engaging in shared decision-making; iv) patient-related barriers to implementation; v) patient-related facilitators to implementation.

CONCLUSIONS

Participants felt that existing care pathways did not meet their needs when pain persisted. Participants preferred matched or hybrid care pathways and suggested that implementation of such pathways should focus on addressing an individual's needs. Adopting a holistic approach, and clarity in shared decision-making, were deemed crucial for effective implementation of LBP pathways in practice. Consumer (patient) engagement in the design of LBP care pathways is recommended.

The Effects of Early Physiotherapy Treatment on Musculoskeletal Injury Outcomes in Military Personnel: A Narrative Review

The risks and incidence rates of musculoskeletal injuries among military personnel are high, and the importance of physiotherapy in treating these injuries is well established. However, what is less clear is whether the timing of commencement of physiotherapy treatment affects musculoskeletal injury outcomes in military personnel. This lack of clarity is exacerbated by the known underreporting of injuries among military personnel, and the resulting self-management of musculoskeletal injuries using analgesics, non-steroidal anti-inflammatories and other means. This narrative review was designed to identify and synthesize current evidence regarding the effects of timing of physiotherapy treatment on musculoskeletal injury outcomes, focusing on potential benefits of early versus typical or delayed commencement of physiotherapy treatment. Overall, current evidence suggests early physiotherapy treatment of musculoskeletal injuries offers distinct advantages over typical or delayed commencement of physiotherapy treatment in military settings. Specifically, it appears early treatment expedites recovery in early phases following injury onset and benefits longer term mental health and well-being. It may also reduce the need for more invasive and costly health care interventions and enable earlier return to training and operational service. Importantly, a cultural shift within military contexts to ensure early reporting of musculoskeletal injuries is required if the benefits of early commencement of physiotherapy treatment are to be achieved.

Implementing a new physiotherapist-led primary care model for low back pain: a qualitative study of patient and primary care team perspectives

Background

Low back pain (LBP) is one of the most common reasons for primary care visits and is the leading contributor to years lived with disability worldwide. The purpose of this study was to understand the perspectives of patients and primary care team members related to their experiences with a new physiotherapist-led primary care model for LBP.

Methods

We conducted an interpretive description qualitative study. Data were collected using a combination of semi-structured interviews and focus group discussions and analyzed using thematic analysis. Participants included adults (> 18 years of age) with LBP and primary care team members who participated in a physiotherapist-led primary care model for LBP in Kingston, Ontario, Canada.

Results

We conducted 18 semi-structured interviews with patients with LBP (10 women; median age of 52) as well as three focus group discussions with a total of 20 primary care team members representing three teams. Four themes (each with sub-themes) were constructed: 1) enhanced primary care delivery for LBP (improved access and engagement in physiotherapy care, improved communication and care integration between the physiotherapist and primary care team, less inappropriate use of healthcare resources); 2) positive patient experiences and perceived outcomes with the new model of care (physiotherapist built therapeutic alliance, physiotherapist provided comprehensive care, improved confidence in managing LBP, decreased impact of pain on daily life); 3) positive primary care team experiences with the new model of care (physiotherapist fit well within the primary care team, physiotherapist provided expertise on LBP for the primary care team, satisfaction in being able to offer a needed service for patients); and 4) challenges implementing the new model of care (challenges with prompt access to physiotherapy care, challenges making the physiotherapist the first contact for LBP, and opportunities to optimize communication between the physiotherapist and primary care team).

Conclusions

A new physiotherapist-led primary care model for LBP was described by patients and primary care team members as contributing to positive experiences and perceived outcomes for patients, primary care team members, and potentially the health system more broadly. Results suggest that this model of care may be a viable approach to support integrated and guideline adherent management of LBP in primary care settings.

A call to action: direct access to physical therapy is highly successful in the US military. When will professional bodies, legislatures, and payors provide the same advantages to all US civilian physical therapists?

OBJECTIVES

In 2000, the American PT Association (APTA) published its Vision statement advocating for DA (DA) to PT. This narrative review of the literature aims to identify the current state of DA in the United States (US) and compare that status to the US Military.

METHODS

Initial PubMed search in the English language with keywords physical therapy (PT), physiotherapy, DA, self-referral, and primary contact from the year 2000 onwards with subsequent focused searches using keywords DA/self-referral/primary contact of physical therapists/physiotherapists on outcomes/autonomous practice/economic impact/patient satisfaction yielded 103 applicable studies on the topic. This paper excluded 40 international articles to focus on US military and civilian research.

RESULTS

Current literature supports Physical Therapists (PTs) in an initial contact role based on patient safety, satisfaction, access to care, efficiency, healthcare utilization, and potential cost savings.

CONCLUSIONS

Despite its success in the US Military, DA to PT in the US civilians remains limited and incomplete. PTs still await unrestricted DA and privileges associated with autonomous practice including the ability to order imaging and prescribe some medications.

Characterization of the procedures and professional practices of primary care physiotherapists in Brazil

BACKGROUND: Physiotherapy interventions are well known and established in secondary and tertiary care. However, within the Brazilian primary health care (PHC), the role of physiotherapists is still under development, and there is a lack of representative data showing how and what is being implemented by these professionals. OBJECTIVE: The aim was to characterize the professional practices of physiotherapists working at PHC in Brazil. METHODS: This is an exploratory study that adopted a descriptive analysis based on the records of physiotherapists, considering assistance and sociodemographic aspects, in the period from 2016 to 2017. The following variables were extracted: region, federative unit and municipality, age group and sex of the attended user, condition/problem, procedure and place of attendance. RESULTS: A total of 318,780 procedures were recorded, concentrated in the South and southeast regions, with a predominance of clinical-assistance procedures and a higher frequency of attendance in Basic Health Units. Among the assisted users, the female gender prevailed in the age group of 20 to 59 years. Low back pain was the most frequently treated condition. CONCLUSION: The professional practices of physiotherapists working at PHC in Brazil were characterized by healthcare, clinical-assistance, preventive and health promotion activities, with emphasis on clinical-assistance practices focused on musculoskeletal conditions, especially low back pain.

Initial presentation for acute low back pain: is early physical therapy associated with healthcare utilization and spending? A retrospective review of a National Database

Background

Early initiation of physical therapy (PT) has been associated with lower healthcare costs and utilization; however, these studies have been limited to single institutions or healthcare systems. Our goal was to assess healthcare utilization and spending among patients who present for the first time with low back pain (LBP), according to whether they received early physical therapy (PT), using a large, nationwide sample; and geographic variation in rates of early PT and 30-day LBP-related spending.

Methods

Using the Truven MarketScan database, we identified nearly 980,000 US adults ages 18–64 years who initially presented with acute LBP from 2010 through 2014 and did not have nonmusculoskeletal causes of LBP. Approximately 110,000 patients (11%) received early PT (≤2 weeks after presentation). We compared healthcare utilization and spending at 30 days and 1 year after presentation between patients who received early PT and those who did not. Alpha = 0.05.

Results

At 30 days, early PT was associated with lower odds of chiropractor visits (odds ratio [OR] = 0.41, 95% confidence interval [CI] = 0.40–0.42), pain specialist visits (OR = 0.49, 95% CI = 0.47–0.51), emergency department visits (OR = 0.51, 95% CI = 0.49–0.54), advanced imaging (OR = 0.57, 95% CI = 0.56–0.58), orthopaedist visits (OR = 0.67, 95% CI = 0.66–0.69), and epidural steroid injections (OR = 0.68, 95% CI = 0.65–0.70). At 1 year, early PT was associated with less healthcare utilization. At 30 days, patients with early PT had lower mean LBP-related spending ($1180 ± $1500) compared with those without early PT ($1250 ± $2560) (P < 0.001). At 1 year, LBP-related spending was significantly less among patients who did not receive early PT ($2510 ± $3826) versus those who did ($2588 ± $3704). Early PT rates (range, 4–25%; P < 0.001) and 30-day LBP-related spending differed by state (range, $421 to −$410; P < 0.001).

Conclusion

Early PT for acute LBP was associated with less 30-day and 1-year healthcare utilization and less 30-day LBP-related spending. Early PT rates and 30-day spending differed by US state.

Does the implementation of clinical practice guidelines for low back and neck pain by physical therapists improve patient outcomes? A systematic review

BACKGROUND

Physical therapy for neck and low back pain is highly variable despite the availability of clinical practice guidelines (CPG). This review aimed to determine the impact of CPG implementation on patient-level outcomes for spinal pain. Implementation strategies were also examined to determine prevalence and potential impact.

METHODS

Multiple databases were searched through April 2021 for studies assessing CPG implementation in physical therapy for neck and low back pain. Articles were screened for eligibility. The Modified Downs and Black checklist was utilized to determine study quality. Due to the heterogeneity between studies, a meta-analysis was not performed.

RESULTS

Twenty-one studies were included in this review. Implementation strategies were significantly varied between studies. Outcomes pertaining to healthcare utilization, pain, and physical functioning were assessed in relation to the implementation of CPGs. Multiple implementation strategies were identified, with Managing Quality as the most frequently utilized key implementation process. Findings indicate CPG implementation decreased healthcare utilization, but inconsistent results were found with physical functioning and pain outcomes.

CONCLUSIONS

CPG implementation appears to have a beneficial effect on healthcare utilization outcomes, but may not impact pain and physical functioning outcomes. Effective CPG implementation strategies remain unknown, though utilizing implementation framework may improve outcomes. More research is needed to determine the most effective implementation strategies and effects on pain and physical function outcomes.

Associations Between Early Chiropractic Care and Physical Therapy on Subsequent Opioid Use Among Persons With Low Back Pain in Arkansas

Objective

The objective of this study was to estimate the association between early use of physical therapy (PT) or chiropractic care and incident opioid use and long-term opioid use in individuals with a low back pain (LBP) diagnosis.

Methods

A retrospective cohort study was conducted using data from Arkansas All Payers' Claims Database. Adults with incident LBP diagnosed in primary care or emergency departments between July 1, 2013, and June 30, 2017, were identified. Participants were required to be opioid naïve in the 6-month baseline period and without cancer, cauda equina syndrome, osteomyelitis, lumbar fracture, and paraplegia/quadriplegia in the entire study period. PT and chiropractic treatment were documented over the ensuing 30 days starting on the date of LBP. Any opioid use and long-term opioid use (LTOU) in 1-year follow-up were assessed. Multivariable logistic regressions controlling for covariates were estimated.

Results

A total of 40 929 individuals were included in the final sample, with an average age of 41 years and 65% being women. Only 5% and 6% received PT and chiropractic service, respectively, within the first 30 days. Sixty-four percent had incident opioid use, and 4% had LTOU in the follow-up period. PT was not associated with incident opioid use (odds ratio [OR], 1.07; 95% confidence interval [CI], 0.98-1.18) or LTOU (OR, 1.19; 95% CI, 0.97-1.45). Chiropractic care decreased the odds of opioid use (OR, 0.88; 95% CI, 0.80-0.97) and LTOU (OR, 0.56; 95% CI, 0.40-0.77).

Conclusion

In this study we found that receipt of chiropractic care, though not PT, may have disrupted the need for opioids and, in particular, LTOU in newly diagnosed LBP.

What do patients referred to physical therapy for a musculoskeletal condition expect? A qualitative assessment

BACKGROUND

Patient expectations related to physical therapy outcomes are commonly collected through surveys and close-ended questionnaires. These methods may not optimally capture patients' expectations for physical therapy, especially in the patients' own words. Louis Gifford identified four questions attempting to guide clinicians' understanding of patients' expectations for physical therapy. However, a qualitative assessment mapping the expectations that patients have prior to starting physical therapy appears to be undocumented.

OBJECTIVES

The aim of this study was to determine patient expectations prior to beginning physical therapy for individuals with musculoskeletal conditions.

DESIGN

Qualitative analysis with structured interviews and open-ended participant responses.

METHODS

Twenty-five people (18 female, 7 male; mean age: 47.04 years) were interviewed prior to their initial physical therapy evaluation using a pragmatic approach rooted in phenomenology. Data were transcribed, coded, and thematized using qualitative data analysis software.

RESULTS

Outcome, education, exercise, evaluation, and cause of pain were key themes expressed by participants. Participants appear to want to better understand their symptoms, how they can improve symptoms, what the clinician will do, and how long they will attend physical therapy. Many participants were not certain where physical therapy fit within their overall healthcare plan, and perceptions of manual therapy were vague.

CONCLUSIONS

These identified themes highlight what patients may expect from a physical therapy experience and clinicians should work to identify and satisfy each patient's individual expectations to optimize outcomes.

Where to start? A two stage residual inclusion approach to estimating influence of the initial provider on health care utilization and costs for low back pain in the US

BACKGROUND

Diagnostic testing and treatment recommendations can vary when medical care is sought by individuals for low back pain (LBP), leading to variation in quality and costs of care. We examine how the first provider seen by an individual at initial diagnosis of LBP influences downstream utilization and costs.

METHODS

Using national private health insurance claims data, individuals age 18 or older were retrospectively assigned to cohorts based on the first provider seen at the index date of LBP diagnosis. Exclusion criteria included individuals with a diagnosis of LBP or any serious medical conditions or an opioid prescription recorded in the 6 months prior to the index date. Outcome measures included use of imaging, back surgery rates, hospitalization rates, emergency department visits, early- and long-term opioid use, and costs (out-of-pocket and total costs of care) twelve months post-index date. We used a two-stage residual inclusion (2SRI) estimation approach comparing copay for the initial provider visit and differential distance as the instrumental variable to reduce selection bias in the choice of first provider, controlling for demographics.

RESULTS

Among 3,799,593 individuals, cost and utilization varied considerably based on the first provider seen by the patient. Copay and differential distance provided similar results, with copay preserving a greater sample size. The frequency of early opioid prescription was significantly lower when care began with an acupuncturist or chiropractor, and highest for those who began with an emergency medicine physician or advanced practice registered nurse (APRN). Long-term opioid prescriptions were low across most providers except physical medicine and rehabilitation physicians and APRNs. The frequency and time to serious illness varied little across providers. Total cost of care was lowest when starting with a chiropractor ($5093) or primary care physician ($5660), and highest when starting with an orthopedist ($9434) or acupuncturist ($9205).

CONCLUSION

The first provider seen by individuals with LBP was associated with large differences in health care utilization, opioid prescriptions, and cost while there were no differences in delays in diagnosis of serious illness.

Today's referral is tomorrow's repeat patient: referrals to and between medical outpatient clinics in a hospital

Background

Unnecessary referrals in Danish hospitals may be contributing to inefficient use of health services already stretched and under pressure and may lead to delayed treatment for patients. Despite a growing awareness in the literature and in practice of issues related to referrals, there has been relatively little research on referrals between specialists in hospital outpatient clinics and how it can be improved. This study aimed to describe the referral patterns to and within the Medical Department at the University Hospital of Southern Denmark. The Medical Department consists of the following medical specialist outpatient clinics; nephrology, pulmonology, endocrinology, cardiovascular, wound outpatient clinic, and a day hospital.

Methods

Two specialist physicians assessed all referrals to the medical specialist outpatient clinics over one month (from 01 September 2019 to 30 September 2019) using data drawn from the Danish electronic patient record system (Cosmic). Data on referral pattern, and patient age and sex, were statistically analysed to identify and characterise patterns of referral.

Results

Four hundred seventy-one (100%) referrals were included in the study. 49.5% (233) of the referrals were from the hospital and 50.5% (238) from general practitioners (GPs). Of the 233 referrals from the hospitals, 31% (72) were from the Medical Department.

Conclusion

The high rate of referrals (31%) from own Medical Department or outpatient clinics may reflect an inefficient internal referral process within the department. Improved collaboration between specialists could have the potential to improve health outcomes, timely access to care and more appropriate healthcare resource utilisation.

Musculoskeletal Imaging for Low Back Pain in Direct Access Physical Therapy Compared to Primary Care: An Observational Study

BACKGROUND

Overutilization of diagnostic imaging is associated with poor outcomes and increased costs. Physical therapists demonstrate the ability to order diagnostic imaging safely and appropriately, and early access to physical therapy reduces unnecessary imaging, lowers healthcare costs, and improves outcomes.

HYPOTHESIS/PURPOSE

The primary purpose of this study was to compare rates of compliance with the National Committee for Quality Assurance - Healthcare Effectiveness Data and Information Set (HEDIS) recommendations for diagnostic imaging in low back pain between physical therapists and primary care providers in young, athletic patients.

STUDY DESIGN

Retrospective cohort study.

METHODS

Military Health System Data Repository (MDR) data from January 2019 to May 2020 was reviewed for compliance with the low back pain HEDIS recommendation. The low back pain imaging HEDIS measure identifies the percentage of patients who did not have an imaging study (plain X-ray, MRI, CT Scan) ordered on the first encounter with a diagnosis of low back pain or in the 28 days following that first diagnosis. Chi-square tests compared HEDIS compliance rates, with α = 0.05 set a priori.

RESULTS

From January 2019 to May 2020, in patients age 18-24, the MDR database identified 1,845 total visits for LBP identified in the Physical Therapy Clinic and 467 total visits for LBP in the Primary Care Clinic. In the Physical Therapy Clinic, 96.7% of encounters did not have imaging ordered within the first 28 days of onset of symptoms, compared with 82.0% in the Primary Care Clinic (p < .001).

CONCLUSIONS

Utilizing data from a national standardized healthcare performance measure, physical therapists practicing in a direct-access setting were significantly more likely than primary care providers to adhere to guidelines for low back pain imaging in young, athletic patients.

Health-Related Quality of Life of Patients Presenting to the Emergency Department with a Musculoskeletal Disorder

Background

Musculoskeletal disorders (MSKDs) are among the most disabling and costly non-fatal health conditions. They may lead to long-term consequences such as chronic pain, physical limitations, and poorer quality of life. They also account for a significant proportion of emergency department visits, representing between 18% and 25% of all visits, depending on country.

Purpose

To assess the health-related quality of life of patients presenting to the emergency department with a MSKD, to convert their answers to utility scores and to explore the association between diverse socio-demographic and clinical variables and patients’ health-related quality of life.

Patients and Methods

This is an analysis of cross-sectional data obtained during the baseline assessment performed as part of a 6-month pragmatic randomized controlled trial conducted in an academic emergency department. We included patients aged 18–80 years with a minor MSKD. The main outcome measures were health-related quality of life (five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression) and utility scores (−0.148 – worse than death, 0 – dead, 0.949 – perfect health) measured with the EQ-5D-5L. Possible associations were explored by comparing scores across subgroups based on certain socio-demographic (eg, age, gender, triage score) and clinical factors (eg, pain interference on function, pain intensity) and with reference values using descriptive statistics (mean, median), rankFD ANOVAs, and χ² tests.

Results

Sixty-nine participants completed the EQ-5D-5L. Mean and median utility scores were, respectively, 0.536 (95% CI: 0.479–0.594) and 0.531 (IQR: 0.356–0.760). Participants with higher levels of pain (<4/10: 0.741, 95% CI: 0.501–0.980; 4–7/10: 0.572, 0.500–0.644; >7/10: 0.433, 0.347–0.518) or pain interference on function (<4/10: 0.685, 95% CI: 0.605–0.764; 4–7/10: 0.463, 0.394–0.533; >7/10: 0.294, 0.126–0.463) presented significantly lower utility scores. No significant differences were found for other socio-demographic characteristics.

Conclusion

In patients with MSKDs who present to the emergency department, higher levels of pain or pain interference are associated with decreased health-related quality of life. These findings need to be confirmed on a larger scale.

A novel movement system screen for primary care providers: a multisite, observational study

CONTEXT

Movement of the human body is essential for the interaction of an individual within their environment and contributes to both physical and emotional quality of life. Movement system disorders (MSDs) are kinesiopathologic conditions that result from either altered movement patterns, trauma, or pathology. A screening tool may facilitate earlier diagnosis and treatment of acute MSDs. This tool could prevent progression to chronic conditions, leading to better patient outcomes and quality of life.

OBJECTIVES

Our study evaluated whether a screening tool would be able to accurately screen individuals for MSDs, explore comorbidities that may predict the prevalence of MSDs, and identify why people do not discuss these problems with their primary care provider (PCP).

METHODS

A multisite, observational study in a primary care setting. Data were analyzed to determine the psychometric properties of the screening question. Logistic regression was performed to explore the relationship of comorbidities with MSDs. Thematic analysis was performed to explore why patients do not discuss these issues with their PCP.

RESULTS

The point prevalence of MSDs was determined to be 78%. The sensitivity of the screening question was determined to be good (70%). Arthritis, obesity, sleep disorders, and gastroesophageal reflux disease (GERD) were significant predictors for an MSD. Thematic analysis regarding why patients do not discuss the MSD with their physician revealed: (1) the perceived lack of importance of the problem; (2) the lack of access to healthcare, and (3) the acuity of the problem.

CONCLUSIONS

Screening for an MSD and associated comorbidities could prevent the transition of acute conditions to chronic conditions. If PCPs can identify predictors and factors associated with an MSD, they may be able to screen for MSDs more effectively. Earlier identification of MSDs may facilitate earlier treatment and prevent costs associated with resulting chronic disorders and persistent pain and disability.

Perceived barriers to accessing physical therapy services in Florida among individuals with low back pain

Background

Low back pain (LBP) affects up to 84% of adults and physical therapy (PT) has been reported to be an effective approach to conservative care. For those individuals with LBP referred to PT, the decision to initiate and follow through with care is influenced by numerous factors. Currently, a paucity of evidence exists to identify barriers for patients with LBP to access PT care. Thus, the purpose of this study was to investigate perceived barriers influencing the decision to pursue PT care in the state of Florida.

Methods

A purposive survey was administered via Qualtrics ESOMAR. Screener questions ensured candidates had LBP, resided in Florida, and were referred to PT. Participants that met the screener questions were offered an opportunity to participate in the full survey. Once a participant completed the full survey, variables assessing LBP, access to PT services, and potential barriers were analyzed. A partial least squares structural equation model (PLS-SEM) via WarpPLS 7.0 was used to explore which of the perceived barriers had the greatest influence on whether an individual with LBP was able to pursue PT care.

Results

The conceptual framework that demonstrated the best fit of direct effects of potential barriers to accessing care included six independent exogenous latent variables: (a) unaware of a PT clinic near their home or work, (b) had children but no childcare for them, (c) had long PT sessions (e.g., 60 min), (d) had more than one PT session per week, (e) had fewer days active per week, and (f) exercised fewer times per day. Together the six variables explained 19% of the variance related to following through with care (R ² = 0.19).

Conclusions

The ability of an individual with LBP to access PT care in the state of Florida is multifactorial. There appears to be three broad factors that are the primary barriers, which include (a) the logistic ability (location and access to childcare) to attend PT treatment, (b) how much time is dedicated to the PT treatment, and (c) activity frequency of the individual seeking care. These findings support previous conceptual frameworks for predicting PT treatment. Practitioners and policy makers should consider these barriers when developing plans for conservative management of LBP in Florida.

Clinician education unlikely effective for guideline-adherent medication prescription in low back pain: systematic review and meta-analysis of RCTs

BACKGROUND

Effectiveness of implementing interventions to optimise guideline-recommended medical prescription in low back pain is not well established.

METHODS

A systematic review and random-effects meta-analyses for dichotomous outcomes with a Paule-Mandel estimator. Five databases and reference lists were searched from inception to 4^th August 2021. Randomised controlled/clinical trials in adults with low back pain to optimise medication prescription were included. Cochrane Risk of Bias 2 tool and GRADE were implemented. The review was registered prospectively with PROSPERO (CRD42020219767).

FINDINGS

Of 3352 unique records identified in the search, seven studies were included and five were eligible for meta-analysis (N=11339 participants). Six of seven studies incorporated clinician education, three studies included audit/feedback components and one study implemented changes in medical records systems. Via meta-analysis, we estimated a non-significant odds-ratio of 0·94 (95% CI (0·77; 1.16), I² = 0%; n=5 studies, GRADE: low) in favour of the intervention group. The main finding was robust to sensitivity analyses.

INTERPRETATION

There is low quality evidence that existing interventions to optimise medication prescription or usage in back pain had no impact. Peer-to-peer education alone does not appear to lead to behaviour change. Organisational and policy interventions may be more effective.

FUNDING

This work was supported by internal institutional funding only.

Alternative payment models and physician treatment decisions: Evidence from lower back pain

The capitated payment model has been used to address the high cost of health care. Under capitation, physicians are compensated with a fixed amount per patient, regardless of the services generated. We provide new evidence on how the capitation payment model changes physicians behaviors by studying the treatment of lower back pain, as this type of treatment provides substantial scope for physicians discretion. We use data from 2003 to 2006 from a large database of employer-sponsored health insurance claims and leverage capitation variation within the plan and physician to mitigate selection concerns. The results show that the treatment intensity-primarily derived from therapy and diagnostic testing -of patients under a capitation system is 7-12% lower than that of similar patients in a non-capitated plan. Furthermore, we find no evidence of increased relapse rates for patients in a capitated plan.

A primary care team approach to secondary prevention of work-related musculoskeletal disorders: Physical therapy perspectives

BACKGROUND

Among work-related conditions in the United States, musculoskeletal disorders (MSDs) account for about thirty-four percent of work absences. Primary care physicians (PCPs) play an essential role in the management of work-related MSDs. For conditions diagnosed as work-related, up to seventeen percent of cases are PCP managed; within these conditions, up to fifty-nine percent are diagnosed as musculoskeletal. Negative factors in treatment success confronting PCPs include time constraints and unfamiliarity with work-related MSDs. A multidimensional team approach to secondary prevention, where PCPs can leverage the expertise of allied health professionals, might provide a useful alternative to current PCP practices for the treatment of work-related MSDs.

OBJECTIVE

Provide the structure of and rationale for an "extended care team" within primary care for the management of work-related MSDs.

METHODS

A systematic literature search, combining medical subject headings and keywords, were used to examine eight peer-reviewed literature databases. Gray literature, such as government documents, were also used.

RESULTS

An extended care team would likely consist of at least nine stakeholders within primary care. Among these stakeholders, advanced practice orthopedic physical therapists can offer particularly focused guidance to PCPs on the evaluation and treatment of work-related MSDs.

CONCLUSIONS

A multidimensional approach has the potential to accelerate access and improve quality of work-related outcomes, while maintaining patient safety.

Effectiveness of a multidisciplinary rehabilitation program in real-world patients with chronic back pain: A pilot cohort data analysis

BACKGROUND

Randomized clinical trials (RCT) suggest a multidisciplinary approach to pain rehabilitation is superior to other active treatments in improving pain intensity, function, disability, and pain interference for patients with chronic pain, with small effect size (ds= 0.20-0.36) but its effectiveness remains unknown in real-world practice.

OBJECTIVE

The current study examined the effectiveness of a multidisciplinary program to a cognitive and behavioral therapy (pain-CBT) in real-world patients with chronic back pain.

METHODS

Twenty-eight patients (M𝑎𝑔𝑒= 57.6, 82.1% Female) completed a multidisciplinary program that included pain psychology and physical therapy. Eighteen patients (M𝑎𝑔𝑒= 58.9, 77.8% Female) completed a CBT-alone program. Using a learning healthcare system, the Pain Catastrophizing Scale, 0-10 Numerical Pain Rating Scale, and Patient-Reported Outcomes Measurement Information System® measures were administered before and after the programs.

RESULTS

We found significant improvement in mobility and pain behavior only after a multidisciplinary program (p's < 0.031; d= 0.69 and 0.55). We also found significant improvement in pain interference, fatigue, depression, anxiety, social role satisfaction, and pain catastrophizing after pain-CBT or multidisciplinary programs (p's < 0.037; ds = 0.29-0.73). Pain ratings were not significantly changed by either program (p's > 0.207).

CONCLUSIONS

The effect of a multidisciplinary rehabilitation program observed in RCT would be generalizable to real-world practice.

Changes in Pain Catastrophizing and Fear-Avoidance Beliefs as Mediators of Early Physical Therapy on Disability and Pain in Acute Low-Back Pain: A Secondary Analysis of a Clinical Trial

OBJECTIVE

The Fear-Avoidance Model of chronic pain (FAM) posits that pain catastrophizing and fear-avoidance beliefs are prognostic for disability and chronicity. In acute low-back pain, early physical therapy (PT) is effective in reducing disability in some patients. How early PT impacts short- and long-term changes in disability for patients with acute pain is unknown. Based on the FAM, we hypothesized that early reductions in pain catastrophizing and fear-avoidance beliefs would mediate early PT's effect on changes in disability (primary outcome) and pain intensity (secondary outcome) over 3 months and 1 year.

SUBJECTS

Participants were 204 patients with low-back pain of < 16 days duration, who enrolled in a clinical trial (NCT01726803) comparing early PT sessions or usual care provided over 4 weeks.

METHODS

Patients completed the Pain Catastrophizing Scale (PCS), Fear-Avoidance Beliefs Questionnaire (FABQ work and physical activity scales) and outcomes (Oswestry Disability Index and Numeric Pain Rating Scale) at baseline, 4 weeks, 3 months, and 1 year. We applied longitudinal mediation analysis with single and multiple mediators.

RESULTS

Early PT led to improvements in disability and pain over 3 months, but not 1 year. In the single mediator model, four-week reductions in pain catastrophizing mediated early PT's effects on 3-month disability and pain intensity improvements, explaining 16% and 22% of the association, respectively, but the effects were small. Pain catastrophizing and fear-avoidance beliefs did not jointly mediate these associations.

CONCLUSIONS

In acute low-back pain, early PT may improve disability and pain outcomes at least partly through reducing patients' catastrophizing.

Predicting Clinical Improvement for Patients With Low Back Pain: Keeping It Simple for Patients Seeking Physical Therapy Care

OBJECTIVE

This study sought to develop and validate an original prediction formula that estimated the probability of success for patients with low back pain (LBP) to achieve a minimal clinically important difference (MCID) on the Modified Low Back Disability Questionnaire (MDQ).

METHODS

Patients were 10 to 90 years old in this retrospective cohort study. Data were extracted from Intermountain Healthcare's registry, Rehabilitation Outcomes Management System: 62,858 patients admitted to physical therapy from 2002 to 2013 formed the training dataset, and 15,128 patients admitted 2015 to 2016 formed the verification dataset. Predicted probability to achieve MCID was compared with the actual percentage who succeeded. Two models were developed: 6-point improvement and 30% improvement. MDQ assessed disability, and numeric pain score assessed pain intensity. Predictive models used restricted cubic splines on age, initial pain, and disability scores for non-linear effects. Sex, symptom duration, and payer type were included as indicator variables. Predicted chance of success was compared with the actual percentage of patients that succeeded. Relative change in R-squared was calculated to assess variable importance in predicting success. Odds ratios for duration of injury and payer were calculated.

RESULTS

A positive trend was observed in both models between predicted and actual success achieved. Both "verification" models appear accurate and closely approximate the "training dataset." Baseline MDQ score was the most important factor to predict a 6-point improvement. Payer type and injury duration were important factors to predict 30% improvement. Best odds to achieve an MCID was having a workers compensation insurance payer and seeking care within 14 days.

CONCLUSION

The 2 models demonstrated an accurate visualization of the chance of patients achieving significant improvement compared with the usual representation of the average rate of improvement for all patients.

IMPACT

Enhancing physical therapists' understanding of the probability of a patient achieving significant clinical improvement can enhance decision-making processes and help physical therapists manage a patient's care more effectively.

Physical Therapy and Health Care Utilization for Older Adults With Lumbar Spinal Stenosis

BACKGROUND AND PURPOSE

Lumbar spinal stenosis (LSS) is associated with high health care utilization for older adults. Physical therapy (PT) offers low medical risk and reduced cost burden with functional outcomes that appear to be equivalent to higher risk interventions such as surgery. However, it is unknown whether receipt of PT following incident LSS diagnosis is associated with reduced health care utilization. The objectives of this study were to: (1) compare health characteristics for Medicare beneficiaries who received outpatient PT within 30 days of incident LSS diagnosis to those who did not; (2) compare the 1-year utilization rates for specific health care services for these 2 groups; and (3) quantify the likelihood of progression to specific health services based on the receipt of PT.

METHODS

This was a retrospective cohort study using nationally representative claims data for Medicare Part B beneficiaries between 2007 and 2010. Lumbar spinal stenosis was determined using International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) codes. Beneficiaries 65 years and older were classified into 2 groups (PT and no PT) based on receipt of PT within 30 days of initial diagnosis. Baseline characteristics were identified at incident diagnosis. Hazard ratios (HRs) were estimated for the risk of receiving health services outcomes including spinal surgery, spinal injections, chiropractic care, advanced imaging, spinal radiographs, opioid medication, nonopioid analgesics, and hospitalizations beginning on day 31 up to 1 year following incident LSS diagnosis.

RESULTS AND DISCUSSION

Among 60 646 Medicare beneficiaries with incident LSS who met the inclusion criteria, 1124 were classified in the PT group and 59 522 in the no PT group. Compared with the PT group, beneficiaries in the no PT group had a greater risk of having hospitalizations (HR = 1.40), opioid medications (HR = 1.29), spinal surgery (HR = 1.29), and spinal radiographs (HR = 1.19) within 1 year.

CONCLUSIONS

Fewer than 2% of Medicare beneficiaries received PT within 30 days of initial LSS diagnosis. Receipt of PT was associated with less utilization of higher risk and costly health services for 1 year. These results may inform practitioners when making early decisions about rehabilitative care for older adults with LSS.
