Item Open Access A value proposition for early physical therapist management of neck pain: a retrospective cohort analysis.(BMC Health Serv Res, 2016-07-12) Horn, Maggie E; Brennan, Gerard P; George, Steven Z; Harman, Jeffrey S; Bishop, Mark DBACKGROUND: Neck pain is one of the most common reasons for entry into the healthcare system. Recent increases in healthcare utilization and medical costs have not correlated with improvements in health. Therefore there is a need to identify management strategies for neck pain that are effective for the patient, cost efficient for the payer and provided at the optimal time during an episode of neck pain. METHODS: One thousand five hundred thirty-one patients who underwent physical therapist management with a primary complaint of non-specific neck pain from January 1, 2008 to December 31, 2012 were identified from the Rehabilitation Outcomes Management System (ROMS) database at Intermountain Healthcare. Patients reporting duration of symptoms less than 4 weeks were designated as undergoing "early" management and patients with duration of symptoms greater than 4 weeks were designated as receiving "delayed" management. These groups were compared using binary logistic regression to examine odds of achieving Minimal Clinically Important Difference (MCID) on the Neck Disability Index (NDI) and Numerical Pain Rating Scale (NPRS). Separate generalized linear modeling examined the effect of timing of physical therapist management on the metrics of value and efficiency. RESULTS: Patients who received early physical therapist management had increased odds of achieving MCID on the NDI (aOR = 2.01, 95 % CI 1.57, 2.56) and MCID on the NPRS (aOR = 1.82, 95 % CI 1.42, 2.38), when compared to patients receiving delayed management. Patients who received early management demonstrated the greatest value in decreasing disability with a 2.27 percentage point change in NDI score per 100 dollars, best value in decreasing pain with a 0.38 point change on the NPRS per 100 dollars. Finally, patients receiving early management were managed more efficiently with a 3.44 percentage point change in NDI score per visit and 0.57 point change in NPRS score per visit. CONCLUSIONS: These findings suggest that healthcare systems that provide pathways for patients to receive early physical therapist management of neck pain may realize improved patient outcomes, greater value and higher efficiency in decreasing disability and pain compared to delayed management. Further research is needed to confirm this assertion.Item Open Access Adding Physical Impairment to Risk Stratification Improved Outcome Prediction in Low Back Pain.(Physical therapy, 2020-09-24) Beneciuk, Jason M; George, Steven ZOBJECTIVE:Identifying subgroups of low back pain (LBP) has the potential to improve prediction of clinical outcomes. Risk stratification is one such strategy that identifies similar characteristics indicative of a common clinical outcome trajectory. The purpose of this study was to determine if an empirically derived subgrouping approach based on physical impairment measures improves information provided from the STarT Back Tool (SBT). METHODS:At baseline in this secondary analysis of a cohort study, patients (N = 144) receiving physical therapy for LBP completed the SBT and tests (active lumbar flexion, extension, lateral bending, and passive straight-leg-raise) from a validated physical impairment index. Clinical outcomes were assessed at 4 weeks and included the Numerical Pain Rating Scale (NPRS) and Oswestry Disability Index (ODI). Exploratory hierarchical agglomerative cluster analysis identified empirically derived subgroups based on physical impairment measures. Independent samples t testing and chi-square analysis assessed baseline subgroup differences in demographic and clinical measures. Spearman rho correlation coefficient was used to assess baseline SBT risk and impairment subgroup relationships, and a 3-way mixed-model ANOVA was used to assessed SBT risk and impairment subgroup relationships with clinical outcomes at 4 weeks. RESULTS:Two physical impairment-based subgroups emerged from cluster analysis: (1) Low-Risk Impairment (n = 119, 81.5%), characterized by greater lumbar mobility and (2) High-Risk Impairment (n = 25, 17.1%), characterized by less lumbar mobility. A weak, positive relationship was observed between baseline SBT risk and impairment subgroups (rs = .170). An impairment-by-SBT risk-by-time interaction effect was observed for ODI scores but not for NPRS scores at 4 weeks. CONCLUSIONS:Physical impairment subgroups were not redundant with SBT risk categories and could improve prediction of 4-week LBP disability outcomes. Physical impairment subgroups did not improve the prediction of 4-week pain intensity scores. IMPACT:Subgroups based on physical impairment and psychosocial risk could lead to better prediction of LBP disability outcomes and eventually allow for treatment options tailored to physical and psychosocial risk.Item Open Access Assessment of Common Comorbidity Phenotypes Among Older Adults With Knee Osteoarthritis to Inform Integrated Care Models.(Mayo Clinic proceedings. Innovations, quality & outcomes, 2021-04) Lentz, Trevor A; Hellkamp, Anne S; Bhavsar, Nrupen A; Goode, Adam P; Manhapra, Ajay; George, Steven ZObjective
To establish the frequency of concordant, discordant, and clinically dominant comorbidities among Medicare beneficiaries with knee osteoarthritis (KOA) and to identify common concordant condition subgroups.Participants and methods
We used a 5% representative sample of Medicare claims data to identify beneficiaries who received a diagnosis of KOA between January 1, 2012, and September 30, 2015, and matched control group without an osteoarthritis (OA) diagnosis. Frequency of 34 comorbid conditions was categorized as concordant, discordant, or clinically dominant among those with KOA and a matched sample without OA. Comorbid condition phenotypes were characterized by concordant conditions and derived using latent class analysis among those with KOA.Results
The study sample included 203,361 beneficiaries with KOA and 203,361 non-OA controls. The largest difference in frequency between the two cohorts was for co-occurring musculoskeletal conditions (23.7% absolute difference), chronic pain syndromes (6.5%), and rheumatic diseases (4.5%), all with a higher frequency among those with knee OA. Phenotypes were identified as low comorbidity (53% of cohort with classification), hypothyroid/osteoporosis (27%), vascular disease (10%), and high medical and psychological comorbidity (10%).Conclusions
Approximately 47% of Medicare beneficiaries with KOA in this sample had a phenotype characterized by one or more concordant conditions, suggesting that existing clinical pathways that rely on single or dominant providers might be insufficient for a large proportion of older adults with KOA. These findings could guide development of integrated KOA-comorbidity care pathways that are responsive to emerging priorities for personalized, value-based health care.Item Open Access Association of Biomarkers with Individual and Multiple Body Sites of Pain: The Johnston County Osteoarthritis Project.(Journal of pain research, 2022-01) Norman, Katherine S; Goode, Adam P; Alvarez, Carolina; Hu, David; George, Steven Z; Schwartz, Todd A; Danyluk, Stephanie T; Fillipo, Rebecca; Kraus, Virginia B; Huebner, Janet L; Cleveland, Rebecca J; Jordan, Joanne M; Nelson, Amanda E; Golightly, Yvonne MIntroduction
Biochemical biomarkers may provide insight into musculoskeletal pain reported at individual or multiple body sites. The purpose of this study was to determine if biomarkers or pressure-pain threshold (PPT) were associated with individual or multiple sites of pain.Methods
This cross-sectional analysis included 689 community-based participants. Self-reported symptoms (ie, pain, aching, or stiffness) were ascertained about the neck, upper back/thoracic, low back, shoulders, elbows, wrist, hands, hips, knees, ankles, and feet. Measured analytes included CXCL-6, RANTES, HA, IL-6, BDNF, OPG and NPY. A standard dolorimeter measured PPT. Logistic regression was used determine the association between biomarkers and PPT with individual and summed sites of pain.Results
Increased IL-6 and HA were associated with knee pain (OR=1.30, 95% CI 1.03, 1.64) and (OR=1.32, 95% CI 1.01, 1.73) respectively; HA was also associated with elbow/wrist/hand pain (OR=1.60, 95% CI 1.22, 2.09). Those with increased NPY levels were less likely to have shoulder pain (OR=0.56, 95% CI 0.33, 0.93). Biomarkers HA (OR=1.50, 95% CI 1.07, 2.10), OPG (OR=1.74, 95% CI 1.00, 3.03), CXCL-6 (OR=1.75, 95% CI 1.02, 3.01) and decreased PPT (OR=3.97, 95% CI 2.22, 7.12) were associated with multiple compared to no sites of pain. Biomarker HA (OR=1.57, 95% CI 1.06, 2.32) and decreased PPT (OR=3.53, 95% CI 1.81, 6.88) were associated with multiple compared to a single site of pain.Conclusion
Biomarkers of inflammation (HA, OPG, IL-6 and CXCL-6), pain (NPY) and PPT may help to understand the etiology of single and multiple pain sites.Item Open Access Can PROMIS measures be used to create subgroups for patients seeking orthopaedic care?(Bone & joint open, 2021-07) George, Steven Z; Yan, Xiaofang; Luo, Sheng; Olson, Steven A; Reinke, Emily K; Bolognesi, Michael P; Horn, Maggie EAims
Patient-reported outcome measures have become an important part of routine care. The aim of this study was to determine if Patient-Reported Outcomes Measurement Information System (PROMIS) measures can be used to create patient subgroups for individuals seeking orthopaedic care.Methods
This was a cross-sectional study of patients from Duke University Department of Orthopaedic Surgery clinics (14 ambulatory and four hospital-based). There were two separate cohorts recruited by convenience sampling (i.e. patients were included in the analysis only if they completed PROMIS measures during a new patient visit). Cohort #1 (n = 12,141; December 2017 to December 2018,) included PROMIS short forms for eight domains (Physical Function, Pain Interference, Pain Intensity, Depression, Anxiety, Sleep Quality, Participation in Social Roles, and Fatigue) and Cohort #2 (n = 4,638; January 2019 to August 2019) included PROMIS Computer Adaptive Testing instruments for four domains (Physical Function, Pain Interference, Depression, and Sleep Quality). Cluster analysis (K-means method) empirically derived subgroups and subgroup differences in clinical and sociodemographic factors were identified with one-way analysis of variance.Results
Cluster analysis yielded four subgroups with similar clinical characteristics in Cohort #1 and #2. The subgroups were: 1) Normal Function: within normal limits in Physical Function, Pain Interference, Depression, and Sleep Quality; 2) Mild Impairment: mild deficits in Physical Function, Pain Interference, and Sleep Quality but with Depression within normal limits; 3) Impaired Function, Not Distressed: moderate deficits in Physical Function and Pain Interference, but within normal limits for Depression and Sleep Quality; and 4) Impaired Function, Distressed: moderate (Physical Function, Pain Interference, and Sleep Quality) and mild (Depression) deficits.Conclusion
These findings suggest orthopaedic patient subgroups differing in physical function, pain, and psychosocial distress can be created from as few as four different PROMIS measures. Longitudinal research is necessary to determine whether these subgroups have prognostic validity.

The purpose of this study was to determine the effect of receiving guideline adherent physical therapy (PT) on clinical outcomes, health care utilization, and charges for health care services in patients with neck pain. A retrospective review of 298 patients with neck pain receiving PT from 2008 to 2011 was performed. Clinical outcomes, utilization, and charges were compared between patients who received guideline adherent care and nonadherent care. Patients in the adherent care group experienced a lower percentage improvement in pain score compared to nonadherent care group (p = .01), but groups did not significantly differ on percentage improvement in disability (p = .32). However, patients receiving adherent care had an average 3.6 fewer PT visits (p < .001) and less charges for PT (p < .001). Additionally, patients receiving adherent care had 7.3 fewer visits to other health care providers (p < .001), one less prescription medication (p = .02) and 43% fewer diagnostic images (p = .02) but did not differ in their charges to other health care providers (p = .68) during the calendar year of undergoing PT. Although receiving guideline adherent care demonstrated positive effects on health care utilization and financial outcomes, there appears to be a trade-off with clinical outcomes.Item Unknown Derivation of a Risk Assessment Tool for Prediction of Long-Term Pain Intensity Reduction After Physical Therapy.(Journal of pain research, 2021-01) Horn, Maggie E; George, Steven Z; Li, Cai; Luo, Sheng; Lentz, Trevor ARationale
Risk assessment tools can improve clinical decision-making for individuals with musculoskeletal pain, but do not currently exist for predicting reduction of pain intensity as an outcome from physical therapy.Aims and objective
The objective of this study was to develop a tool that predicts failure to achieve a 50% pain intensity reduction by 1) determining the appropriate statistical model to inform the tool and 2) select the model that considers the tradeoff between clinical feasibility and statistical accuracy.Methods
This was a retrospective, secondary data analysis of the Optimal Screening for Prediction of Referral and Outcome (OSPRO) cohort. Two hundred and seventy-nine individuals seeking physical therapy for neck, shoulder, back, or knee pain who completed 12-month follow-up were included. Two modeling approaches were taken: a longitudinal model included demographics, presence of previous episodes of pain, and regions of pain in addition to baseline and change in OSPRO Yellow Flag scores to 12 months; two comparison models included the same predictors but assessed only baseline and early change (4 weeks) scores. The primary outcome was failure to achieve a 50% reduction in pain intensity score at 12 months. We compared the area under the curve (AUC) to assess the performance of each candidate model and to determine which to inform the Personalized Pain Prediction (P3) risk assessment tool.Results
The baseline only and early change models demonstrated lower accuracy (AUC=0.68 and 0.71, respectively) than the longitudinal model (0.79) but were within an acceptable predictive range. Therefore, both baseline and early change models were used to inform the P3 risk assessment tool.Conclusion
The P3 tool provides physical therapists with a data-driven approach to identify patients who may be at risk for not achieving improvements in pain intensity following physical therapy.Item Open Access Description of Common Clinical Presentations and Associated Short-Term Physical Therapy Clinical Outcomes in Patients With Neck Pain.(Arch Phys Med Rehabil, 2015-10) Horn, Maggie E; Brennan, Gerard P; George, Steven Z; Harman, Jeffrey S; Bishop, Mark DOBJECTIVE: To determine the effect of clinical presentations of neck pain on short-term physical therapy outcomes. DESIGN: Retrospective analysis of pair-matched groups from a clinical cohort. SETTING: Thirteen outpatient physical therapy clinics in 1 health care system. PARTICIPANTS: Patients (N=1069) grouped by common clinical presentations of neck pain: nonspecific neck pain (NSNP) with duration <4 weeks; NSNP with duration >4 weeks; neck pain with arm pain; neck pain with headache; and neck pain from whiplash. INTERVENTION: Conservative interventions provided by physical therapists. MAIN OUTCOME MEASURES: Neck Disability Index (NDI) and numerical pain rating scale (NPRS) recorded at the initial and last visits. The main outcome of interest was achieving recovery status on the NDI. Changes in NDI and NPRS were compared between clinical presentation groups. RESULTS: Compared with patients presenting with NSNP >4 weeks, patients with NSNP <4 weeks had increased odds of achieving recovery status on the NDI (P<.0001) and demonstrated the greatest changes in clinical outcomes of pain (P≤.0001) and disability (P≤.0001). Patients with neck pain and arm pain demonstrated an increased odds of achieving recovery status on the NDI (P=.04) compared with patients presenting with NSNP >4 weeks. CONCLUSIONS: Treating patients with NSNP within <4 weeks of onset of symptoms may lead to improved clinical outcomes from physical therapy compared with other common clinical presentations.Item Open Access Exercise-induced pain intensity predicted by pre-exercise fear of pain and pain sensitivity.(Clin J Pain, 2011-06) Bishop, Mark D; Horn, Maggie E; George, Steven ZOBJECTIVES: Our primary goals were to determine whether preexisting fear of pain and pain sensitivity contributed to post-exercise pain intensity. METHODS: Delayed-onset muscle pain was induced in the trunk extensors of 60 healthy volunteers using an exercise paradigm. Levels of fear of pain and experimental pain sensitivity were measured before exercise. Pain intensity in the low back was collected at 24 and 48 hours post-exercise. Participants were grouped based on pain intensity. Group membership was used as the dependent variable in separate regression models for 24 and 48 hours. Predictor variables included fear, pain sensitivity, torque lost during the exercise protocol, and demographic variables. RESULTS: The final models predicting whether a participant reported clinically meaningful pain intensity at 24 hours only included baseline fear of pain at each level of pain intensity tested. The final model at 48 hours included average baseline pain sensitivity and the loss of muscle performance during the exercise protocol for 1 level of pain intensity tested (greater than 35 mm of 100 mm). DISCUSSION: Combined, these findings suggest that the initial reports of pain after injury may be more strongly influenced by fear whereas the inflammatory process and pain sensitivity may play a larger role for later pain intensity reports.Item Open Access Framework for improving outcome prediction for acute to chronic low back pain transitions.(Pain reports, 2020-03-04) George, Steven Z; Lentz, Trevor A; Beneciuk, Jason M; Bhavsar, Nrupen A; Mundt, Jennifer M; Boissoneault, JeffClinical practice guidelines and the Federal Pain Research Strategy (United States) have recently highlighted research priorities to lessen the public health impact of low back pain (LBP). It may be necessary to improve existing predictive approaches to meet these research priorities for the transition from acute to chronic LBP. In this article, we first present a mapping review of previous studies investigating this transition and, from the characterization of the mapping review, present a predictive framework that accounts for limitations in the identified studies. Potential advantages of implementing this predictive framework are further considered. These advantages include (1) leveraging routinely collected health care data to improve prediction of the development of chronic LBP and (2) facilitating use of advanced analytical approaches that may improve prediction accuracy. Furthermore, successful implementation of this predictive framework in the electronic health record would allow for widespread testing of accuracy resulting in validated clinical decision aids for predicting chronic LBP development.Item Open Access High-Impact Chronic Pain Transition in Lumbar Surgery Recipients.(Pain medicine (Malden, Mass.), 2023-03) Cook, Chad E; George, Steven Z; Lentz, Trevor; Park, Christine; Shaffrey, Christopher I; Goodwin, C Rory; Than, Khoi D; Gottfried, Oren NObjective
High-impact chronic pain (HICP) is a term that characterizes the presence of a severe and troubling pain-related condition. To date, the prevalence of HICP in lumbar spine surgery recipients and their HICP transitions from before to after surgery are unexplored. The purpose was to define HICP prevalence, transition types, and outcomes in lumbar spine surgery recipients and to identify predictors of HICP outcomes.Methods
In total, 43,536 lumbar surgery recipients were evaluated for HICP transition. Lumbar spine surgery recipients were categorized as having HICP preoperatively and at 3 months after surgery if they exhibited chronic and severe pain and at least one major activity limitation. Four HICP transition groups (Stable Low Pain, Transition from HICP, Transition to HICP, and Stable High Pain) were categorized and evaluated for outcomes. Multivariate multinomial modeling was used to predict HICP transition categorization.Results
In this sample, 15.1% of individuals exhibited HICP preoperatively; this value declined to 5.1% at 3 months after surgery. Those with HICP at baseline and 3 months had more comorbidities and worse overall outcomes. Biological, psychological, and social factors predicted HICP transition or Stable High Pain; some of the strongest involved social factors of 2 or more to transition to HICP (OR = 1.43; 95% CI = 1.21-1.68), and baseline report of pain/disability (OR = 3.84; 95% CI = 3.20-4.61) and psychological comorbidity (OR = 1.78; 95% CI = 1.48-2.12) to Stable Stable High Pain.Conclusion
The percentage of individuals with HICP preoperatively (15.1%) was low, which further diminished over a 3-month period (5.1%). Postoperative HICP groups had higher levels of comorbidities and worse baseline outcomes scores. Transition to and maintenance of HICP status was predicted by biological, psychological, and social factors.Item Open Access High-impact chronic pain transition in surgical recipients with cervical spondylotic myelopathy.(Journal of neurosurgery. Spine, 2022-01) Cook, Chad E; George, Steven Z; Asher, Anthony L; Bisson, Erica F; Buchholz, Avery L; Bydon, Mohamad; Chan, Andrew K; Haid, Regis W; Mummaneni, Praveen V; Park, Paul; Shaffrey, Christopher I; Than, Khoi D; Tumialan, Luis M; Wang, Michael Y; Gottfried, Oren NObjective
High-impact chronic pain (HICP) is a recently proposed metric that indicates the presence of a severe and troubling pain-related condition. Surgery for cervical spondylotic myelopathy (CSM) is designed to halt disease transition independent of chronic pain status. To date, the prevalence of HICP in individuals with CSM and their HICP transition from presurgery is unexplored. The authors sought to define HICP prevalence, transition, and outcomes in patients with CSM who underwent surgery and identify predictors of these HICP transition groups.Methods
CSM surgical recipients were categorized as HICP at presurgery and 3 months if they exhibited pain that lasted 6-12 months or longer with at least one major activity restriction. HICP transition groups were categorized and evaluated for outcomes. Multivariate multinomial modeling was used to predict HICP transition categorization.Results
A majority (56.1%) of individuals exhibited HICP preoperatively; this value declined to 15.9% at 3 months (71.6% reduction). The presence of HICP was also reflective of other self-reported outcomes at 3 and 12 months, as most demonstrated notable improvement. Higher severity in all categories of self-reported outcomes was related to a continued HICP condition at 3 months. Both social and biological factors predicted HICP translation, with social factors being predominant in transitioning to HICP (from none preoperatively).Conclusions
Many individuals who received CSM surgery changed HICP status at 3 months. In a surgical population where decisions are based on disease progression, most of the changed status went from HICP preoperatively to none at 3 months. Both social and biological risk factors predicted HICP transition assignment.Item Open Access Implications of practice setting on clinical outcomes and efficiency of care in the delivery of physical therapy services.(J Orthop Sports Phys Ther, 2014-12) Childs, John D; Harman, Jeffrey S; Rodeghero, Jason R; Horn, Maggie; George, Steven ZSTUDY DESIGN: Retrospective analysis of episodes of care. OBJECTIVE: To assess the implications of practice setting (hospital outpatient settings versus private practice) on clinical outcomes and efficiency of care in the delivery of physical therapy services. BACKGROUND: Many patients with musculoskeletal conditions benefit from care provided by physical therapists. The majority of physical therapists deliver services in either a private practice setting or in a hospital outpatient setting. There have not been any recent studies comparing whether clinical outcomes or efficiency of care differ based on practice setting. METHODS: Practices that use the Focus On Therapeutic Outcomes, Inc system were surveyed to determine the specific type of setting in which outcomes were collected in patients with musculoskeletal impairments. Patient outcome data over 12 months (2011-2012) were extracted from the database and analyzed to identify differences in the functional status achieved and the efficiency of the care delivery process between private practices and hospital outpatient settings. RESULTS: The data suggest that patients experience more efficient care when receiving physical therapy in hospital outpatient settings compared to private practice settings, as demonstrated by 3.1 points of greater improvement in functional status over 2.9 fewer physical therapy visits. However, the difference in improvement between settings is less than the minimum clinically important difference of 9 points in functional status outcome score. CONCLUSION: In this cohort, our data suggest that more efficient care was delivered in the hospital outpatient setting compared to the private practice setting. However, we cannot conclude that care delivered in the hospital setting is more cost-effective, because it is possible that any difference in efficiency of care favoring the hospital outpatient setting is more than offset by higher costs of care.Item Open Access Improving Veteran Access to Integrated Management of Back Pain (AIM-Back): Protocol for an Embedded Pragmatic Cluster-Randomized Trial.(Pain medicine (Malden, Mass.), 2020-12) George, Steven Z; Coffman, Cynthia J; Allen, Kelli D; Lentz, Trevor A; Choate, Ashley; Goode, Adam P; Simon, Corey B; Grubber, Janet M; King, Heather; Cook, Chad E; Keefe, Francis J; Ballengee, Lindsay A; Naylor, Jennifer; Brothers, Joseph Leo; Stanwyck, Catherine; Alkon, Aviel; Hastings, Susan NBackground
Coordinated efforts between the National Institutes of Health, the Department of Defense, and the Department of Veterans Affairs have built the capacity for large-scale clinical research investigating the effectiveness of nonpharmacologic pain treatments. This is an encouraging development; however, what constitutes best practice for nonpharmacologic management of low back pain (LBP) is largely unknown.Design
The Improving Veteran Access to Integrated Management of Back Pain (AIM-Back) trial is an embedded pragmatic cluster-randomized trial that will examine the effectiveness of two different care pathways for LBP. Sixteen primary care clinics will be randomized 1:1 to receive training in delivery of 1) an integrated sequenced-care pathway or 2) a coordinated pain navigator pathway. Primary outcomes are pain interference and physical function (Patient-Reported Outcomes Measurement Information System Short Form [PROMIS-SF]) collected in the electronic health record at 3 months (n=1,680). A subset of veteran participants (n=848) have consented to complete additional surveys at baseline and at 3, 6, and 12 months for supplementary pain and other measures.Summary
AIM-Back care pathways will be tested for effectiveness, and treatment heterogeneity will be investigated to identify which veterans may respond best to a given pathway. Health care utilization patterns (including opioid use) will also be compared between care pathways. Therefore, the AIM-Back trial will provide important information that can inform the future delivery of nonpharmacologic treatment of LBP.Item Open Access Influence of Initial Provider on Health Care Utilization in Patients Seeking Care for Neck Pain.(Mayo Clinic Proceedings: Innovations, Quality & Outcomes, 2017-12) Horn, Maggie E; George, Steven Z; Fritz, Julie MTo examine patients seeking care for neck pain to determine associations between the type of provider initially consulted and 1-year health care utilization.A retrospective cohort of 1702 patients (69.25% women, average age, 45.32±14.75 years) with a new episode of neck pain who consulted a primary care provider, physical therapist (PT), chiropractor (DC), or specialist from January 1, 2012, to June 30, 2013, was analyzed. Descriptive statistics were calculated for each group, and subsequent 1-year health care utilization of imaging, opioids, surgery, and injections was compared between groups.Compared with initial primary care provider consultation, patients consulting with a DC or PT had decreased odds of being prescribed opioids within 1 year from the index visit (DC: adjusted odds ratio [aOR], 0.54; 95% CI, 0.39-0.76; PT: aOR, 0.59; 95% CI, 0.44-0.78). Patients consulting with a DC additionally demonstrated decreased odds of advanced imaging (aOR, 0.43; 95% CI, 0.15-0.76) and injections (aOR, 0.34; 95% CI, 0.19-0.56). Initiating care with a specialist or PT increased the odds of advanced imaging (specialist: aOR, 2.96; 95% CI, 2.01-4.38; PT: aOR, 1.57; 95% CI, 1.01-2.46), but only initiating care with a specialist increased the odds of injections (aOR, 3.21; 95% CI, 2.31-4.47).Initially consulting with a nonpharmacological provider may decrease opioid exposure (PT and DC) over the next year and also decrease advanced imaging and injections (DC only). These data provide an initial indication of how following recent practice guidelines may influence health care utilization in patients with a new episode of neck pain.Item Open Access Interventions for the Management of Acute and Chronic Low Back Pain: Revision 2021.(The Journal of orthopaedic and sports physical therapy, 2021-11) George, Steven Z; Fritz, Julie M; Silfies, Sheri P; Schneider, Michael J; Beneciuk, Jason M; Lentz, Trevor A; Gilliam, John R; Hendren, Stephanie; Norman, Katherine SLow back pain (LBP) remains a musculoskeletal condition with an adverse societal impact. Globally, LBP is highly prevalent and a leading cause of disability. This is an update to the 2012 Academy of Orthopaedic Physical Therapy (AOPT), formerly the Orthopaedic Section of the American Physical Therapy Association (APTA), clinical practice guideline (CPG) for LBP. The overall objective of this update was to provide recommendations on interventions delivered by physical therapists or studied in care settings that included physical therapy providers. It also focused on synthesizing new evidence, with the purpose of making recommendations for specific nonpharmacologic treatments.

Psychologically informed practice is one way to deliver this type of care through the integration of biopsychosocial interventions into patient management. An important component of psychologically informed practice is patient centered communication. However, there is little research on how to effectively implement patient centered communication into pre-licensure training for physical therapists. METHODS:Thirty Doctor of Physical Therapy (DPT) students took part in an educational intervention that consisted of one 4-h didactic teaching session and three 1-h experiential learning sessions. Prior to the first session, students performed an examination of a standardized patient with chronic low back pain and were assessed on psychologically informed physical therapy (PIPT) adherent behaviors via a rating scale. Students also completed the Pain Attitudes and Beliefs Scale (PABS-PT). After the last experiential session, students evaluated another standardized patient and were reassessed on PIPT adherent behaviors. Students retook the PABS-PT and qualitative data was also collected. RESULTS:After the educational intervention, students had positive changes in their pain attitudes and belief scores indicating a stronger orientation toward a psychosocial approach to patient care (p < 0.05). Additionally, after the intervention, students showed improvements in their adherence to using PIPT behaviors in their simulated patient interactions (p < 0.05). Qualitatively, students reported a high acceptability of the educational intervention with common themes indicating improved confidence with treating and communicating with complex patients. CONCLUSION:Students had attitudes and beliefs shift towards a more psychosocial orientation and demonstrated improved PIPT behaviors in simulated patient interactions after a brief educational intervention. Future research should investigate best practices for implementation of psychologically informed physical therapy for licensed clinicians.Item Open Access Longitudinal Monitoring of Pain Associated Distress with the Optimal Screening for Prediction of Referral and Outcome Yellow Flag (OSPRO-YF) Tool: Predicting Reduction Pain Intensity and Disability.(Archives of physical medicine and rehabilitation, 2020-06-26) George, Steven Z; Li, Cai; Luo, Sheng; Horn, Maggie E; Lentz, Trevor AOBJECTIVE:To investigate the Optimal Screening for Prediction of Referral and Outcome Yellow Flag (OSPRO-YF) tool for longitudinal monitoring of pain associated distress with the goal of improving prediction of 50% reduction in pain intensity and disability outcomes. DESIGN:Cohort study with 12-month follow-up after initial care episode SETTING: Ambulatory care, participants seeking care from out-patient physical therapy clinics PARTICIPANTS: Participants were seeking care for primary complaint of neck, low back, knee or shoulder pain. This secondary analysis included 440 subjects (62.5% female; mean age 45.1± 17) at baseline with n=279 (63.4%) providing follow-up data at 12 months. INTERVENTIONS:Not applicable MAIN OUTCOME MEASURES: 50% reduction (baseline to 12-month follow-up) in pain intensity and self-reported disability RESULTS: Trends for prediction accuracy were similar for all versions of the OSPRO-YF. For predicting 50% reduction in pain intensity, model fit met the statistical criterion for improvement (i.e., p < 0.05) with each additional time point added from baseline. Model discrimination improved statistically when the 6-month to 12-month change was added to the model (Area Under the Curve = 0.849, p = 0.003). For predicting 50% reduction in disability, there was no evidence of improvement in model fit or discrimination from baseline with the addition of 4-week, 6-month, or 12-month changes (p's > 0.05). CONCLUSIONS:These results suggested that longitudinal monitoring improved prediction accuracy for reduction in pain intensity, but not for disability reduction. Differences in OSPRO-YF item sets (10 vs. 17 items) or scoring methods (simple summary score vs. yellow flag count) did not impact predictive accuracy for pain intensity, providing flexibility for implementing this tool in practice settings.Item Open Access Magnitude of spinal muscle damage is not statistically associated with exercise-induced low back pain intensity.(Spine J, 2011-12) Bishop, Mark D; Horn, Maggie E; Lott, Donovan J; Arpan, Ishu; George, Steven ZBACKGROUND CONTEXT: Findings on imaging of noncontractile anatomic abnormalities and the intensity of low back pain have weak associations because of false-positive rates among asymptomatic individuals. This association might be stronger for contractile tissues. PURPOSE: The purpose of this study was to examine the relationship between location and reports of pain intensity in the low back and exercise-induced muscle damage to the lumbar paraspinal muscles. STUDY DESIGN: Nondiagnostic observational study in a laboratory setting. METHODS: Delayed onset muscle soreness was induced in the low back of healthy pain-free volunteers. Measures of pain intensity (100-mm visual analog scale [VAS]) and location (area on the pain diagram) were taken before and 48 hours after exercise. Muscle damage was quantified using mechanical pain thresholds, motor performance deficits, and transverse relaxation time (T2)-weighted magnetic resonance imaging (MRI). Changes pre- to postexercise in signal intensity on T2-weighted imaging within the erector spinae, pain intensity, pain area, mechanical pain threshold, and isometric torque were assessed using paired t tests. Bivariate correlations were conducted to assess associations among muscle damage, pain intensity, and pain drawing area. RESULTS: Twenty participants volunteered (11 women; average age, 22.3 years; average body mass index, 23.5) for study participation. Reports of pain intensity at 48 hours ranged from 0 to 59 mm on the VAS. Muscle damage was confirmed by reductions in mechanical threshold (p=.011) and motor performance (p<.001) and by changes in T2-weighted MRI (p=.007). This study was powered to find an association of at least r=0.5 to be statistically significant. Correlations of continuous variables revealed no significant correlations between pain intensity and measures of muscle damage (ranging between -0.075 and 0.151). There was a significant association between the remaining torque deficit at 48 hours and pain area. CONCLUSIONS: The results of this study indicate that there was no association between the magnitude of muscle damage in the lumbar erector spinae and reported pain intensity in the low back. In future studies, larger cohorts may report statistically significant associations, but our data suggest that there will be low magnitude potentially indicating limited clinical relevance.
