Unaccounted for Pitch Volume Among Adolescent Baseball Pitchers During a Travel Baseball Season.

OBJECTIVE: The primary aim was to compare differences in live game pitch counts (LGPCs) with all pitch counts (APCs) over the course of a youth baseball season. DESIGN: Prospective longitudinal study. SETTING: Midwest youth travel baseball. PARTICIPANTS: Ten male baseball players part of a youth baseball travel team. VARIABLES: Demographic data, pitch counts (practice, game, warm-up, and bullpen), innings pitched, and recommended rest days. MAIN OUTCOME MEASURES: Live pitch counts compared with APCs and the relationship to recommended rest days. RESULTS: During the season, 7866 pitches were recorded among 9 pitchers. By using the LGPC method alone, 42.5% of the pitches were unaccounted for. When considering age-specific rest days suggested by Pitch Smart Guidelines (PSGs), there were 104 rest days unaccounted for by using the live game pitch method. CONCLUSION: There is a high number of unaccounted for pitches and an underestimation of rest days per outing when using live game methods. Revisions to the PSGs that include all pitches should be considered to accurately reflect pitching volume, which may be associated with the rising rate of injuries among these athletes.

High-Impact Chronic Pain Transition in Lumbar Surgery Recipients.

OBJECTIVE: 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.

Creation and Validation of the Select Medical Patient Reported Experience Measure for Physical and Occupational Therapy Outpatient Clinics.

OBJECTIVE: This study describes the creation and examination of the internal consistency, content validity, construct/structural validity, and criterion/concurrent validity of the Select Medical Patient Reported Experience Measure (SM-PREM). DESIGN: Observational study design. SETTING: 1054 Outpatient physical and occupational therapy locations in North America. PARTICIPANTS: The study included 89,205 patients with various musculoskeletal disorders (N=89,205). INTERVENTION: Not applicable. MAIN OUTCOME MEASURES: Content validity was described, and internal consistency, construct/structural validity (factor analysis), and criterion/concurrent validity were analyzed, with concurrent validity compared against patient reported outcomes (PROM), the Net Promoter Scale, and the Orebro Musculoskeletal Screening Questionnaire-12. RESULTS: Exploratory and confirmatory factor analysis of the SM-PREM yielded 3 dimensions, each with a very strong internal consistency (>.850). The SM-PREM yielded statistically significant results in all areas, with values that reflected minimal to fair association with PROMs. CONCLUSION: The SM-PREM appears to capture a unique construct compared to PROMs. The 11-item tool has 3 definitive dimensions and exhibits strong internal consistency. The tool may be useful in examining patient experience in patients with musculoskeletal injuries seen by physical and occupational therapists.

Effect of a Patient Engagement, Education, and Restructuring of Cognitions (PEERC) approach on conservative care in rotator cuff related shoulder pain treatment: a randomized control trial.

BACKGROUND: Despite similar outcomes for surgery and physical therapy (PT), the number of surgeries to treat rotator cuff related shoulder pain (RCRSP) is increasing. Interventions designed to enhance treatment expectations for PT have been shown to improve patient expectations, but no studies have explored whether such interventions influence patient reports of having had surgery, or being scheduled for surgery. The purpose of this randomized clinical trial was to examine the effect of a cognitive behavioral intervention aimed at changing expectations for PT on patient-report of having had or being scheduled for surgery and on the outcomes of PT. METHODS: The Patient Engagement, Education, and Restructuring of Cognitions (PEERC) intervention, was designed to change expectations regarding PT. PEERC was evaluated in a randomized, pragmatic "add-on" trial in by randomizing patients with RCRSP to receive either PT intervention alone (PT) or PT + PEERC. Fifty-four (54) individuals, recruited from an outpatient hospital-based orthopedic clinic, were enrolled in the trial (25 randomized to PT, 29 randomized to PT + PEERC). Outcomes assessed at enrollment, 6 weeks, discharge, and six months after discharge included the patient report of having had surgery, or being scheduled for surgery (primary) and satisfaction with PT outcome, pain, and function (secondary outcomes). RESULTS: The average age of the 54 participants was 51.81; SD = 12.54, and 63% were female. Chronicity of shoulder pain averaged 174.61 days; SD = 179.58. Study results showed that at the time of six months follow up, three (12%) of the participants in the PT alone group and one (3.4%) in the PT + PEERC group reported have had surgery or being scheduled for surgery (p = .32). There were no significant differences between groups on measures of satisfaction with the outcome of PT (p = .08), pain (p = .58) or function (p = .82). CONCLUSIONS: In patients with RCRSP, PT plus the cognitive behavioral intervention aimed at changing expectations for PT provided no additional benefit compared to PT alone with regard to patient report of having had surgery, or being scheduled to have surgery, patient reported treatment satisfaction with the outcome of PT, or improvements in pain, or function. TRIAL REGISTRATION: The trial is registered on ClinicalTrials.gov: NCT03353272 (27/11/2017).

Association between radiographic soft-tissue thickness and increased length of stay, operative time, and infection rate after reverse shoulder arthroplasty.

BACKGROUND: Reverse shoulder arthroplasty (RSA) is a widely performed surgical procedure to address various shoulder pathologies. Several studies have suggested that radiographic soft-tissue thickness may play a role in predicting complications after orthopedic surgery, but there have been limited studies determining the use of radiographic soft-tissue thickness in RSA. The purpose of this study was to evaluate whether radiographic soft-tissue thickness could predict clinical outcomes after RSA and compare the predictive capabilities against body mass index (BMI). We hypothesized that increased radiographic shoulder soft-tissue thickness would be a strong predictor of operative time, length of stay (LOS), and infection in elective RSA. MATERIAL AND METHODS: A retrospective review of patients undergoing RSA at an academic institution was conducted. Preoperative radiographic images were evaluated including measurements of the radius from the humeral head center to the skin (HS), deltoid radius-to-humeral head radius ratio (DHR), deltoid size, and subcutaneous tissue size. Different correlation coefficients were used to analyze various types of relationships, and the strength of these associations was classified based on predefined boundaries. Subsequently, multivariable linear and logistic regressions were performed to determine whether HS, DHR, deltoid size, and subcutaneous tissue size could predict LOS, operative time, or infection while controlling for patient factors. RESULTS: HS was the most influential factor in predicting both operative time and LOS after RSA, with strong associations indicated by standardized ß coefficients of 0.234 for operative time and 0.432 for LOS. Subcutaneous tissue size, deltoid size, and DHR also showed stronger predictive values than BMI for both outcomes. In terms of prosthetic joint infection, HS, deltoid size, and DHR were significant predictors, with HS demonstrating the highest predictive power (Nagelkerke R2 = 0.44), whereas BMI did not show a statistically significant association with infection. Low event counts resulted in wide confidence intervals for odds ratios in the infection analysis. CONCLUSION: Greater shoulder soft-tissue thickness as measured with concentric circles on radiographs is a strong predictor of operative time, LOS, and postoperative infection in elective primary RSA patients.

Association of Burden and Prevalence of Arthritis With Disparities in Social Risk Factors, Findings From 17 US States.

INTRODUCTION: Social risks previously have been associated with arthritis prevalence and costs. Although social risks often cluster among individuals, no studies have examined associations between multiple social risks within the same individual. Our objective was to determine the association between individual and multiple social risks and the prevalence and burden of arthritis by using a representative sample of adults in 17 US states. METHODS: Data are from the 2017 Behavioral Risk Factor Surveillance System. Respondents were 136,432 adults. Social risk factors were food insecurity, housing insecurity, financial insecurity, unsafe neighborhoods, and health care access hardship. Weighted χ2 and logistic regression analyses, controlling for demographic characteristics, measures of socioeconomic position, and other health conditions examined differences in arthritis prevalence and burden by social risk factor and by a social risk index created by summing the social risk factors. RESULTS: We observed a gradient in the prevalence and burden of arthritis. Compared with those reporting 0 social risk factors, respondents reporting 4 or more social risk factors were more likely to have arthritis (adjusted odds ratio [AOR], 1.92; 95% CI, 1.57-2.36) and report limited usual activities (AOR, 2.97; 95% CI, 2.20-4.02), limited work (AOR, 2.72; 95% CI, 2.06-3.60), limited social activities (AOR, 3.10; 95% CI, 2.26-4.26), and severe joint pain (AOR, 1.86; 95% CI, 1.44-2.41). CONCLUSION: Incremental increases in the number of social risk factors were independently associated with higher odds of arthritis and its burden. Intervention efforts should address the social context of US adults to improve health outcomes.

What does it take to facilitate the integration of clinical practice guidelines for the management of low back pain into practice? Part 2: A strategic plan to activate dissemination.

Low back pain (LBP) is the leading cause of disability worldwide among all musculoskeletal disorders despite an intense focus in research efforts. Researchers and decision makers have produced multiple clinical practice guidelines for the rehabilitation of LBP, which contain specific recommendations for clinicians. Adherence to these recommendations may have several benefits, such as improving the quality of care for patients living with LBP, by ensuring that the best evidence-based care is being delivered. However, clinicians' adherence to recommendations from these guidelines is low and numerous implementation barriers and challenges, such as complexity of information and sheer volume of guidelines have been documented. In a previous paper, we performed a systematic review of the literature to identify high-quality clinical practice guidelines on the management of LBP, and developed a concise yet comprehensive infographic that summarizes the recommendations from these guidelines. Considering the wealth of scientific evidence, passive dissemination alone of this research knowledge is likely to have limitations to help clinicians implement these recommendations into routine practice. Thus, an active and engaging dissemination strategy, aimed at improving the implementation and integration of specific recommendations into practice is warranted. In this paper, we argue that a conceptual framework, such as the theoretical domains framework, could facilitate the implementation of these recommendations into clinical practice. Specifically, we present a systematic approach that could serve to guide the development of a theory-informed knowledge translation intervention as a means to overcome implementation challenges in rehabilitation of LBP.

What does it take to facilitate the integration of clinical practice guidelines for the management of low back pain into practice? Part 1: A synthesis of recommendation.

BACKGROUND: Despite the emergence of multiple clinical practice guidelines (CPGs) for the rehabilitation of low back pain (LBP) over the last decade, self-reported levels of disability in this population have not improved. This may be explained by the numerous implementation barriers, such as the complexity of information and sheer volumes of CPGs. OBJECTIVES: The purpose of this study was to summarize the evidence and recommendations from the most recent and high-quality CPGs on the rehabilitation management of LBP by developing an infographic summarizing the recommendations to facilitate dissemination into clinical practice. METHODS: We performed a systematic review of high-quality CPGs with an emphasis on rehabilitation approaches. We searched major health-related research databases (e.g., PubMed, CINAHL, and PEDro). We performed quality assessment via the AGREE-II instrument. Contents of the CPGs were synthesized by extracting recommendations, which were then compared to one another to identify consistencies based on an iterative evaluation process. RESULTS: We identified and assessed 5 recent high-quality CPGs. We synthesized 13 recommendations on the rehabilitation management of LBP (2 for screening procedures, 3 for assessment procedures, and 8 involving treatment approaches) and 2 underlying principles were highlighted. These results were then synthetized and illustrated in a concise infographic that serves as a conceptual roadmap that identifies the specific behavior changes (i.e., adoption of CPGs' recommendations) rehabilitation professionals should adopt in order to integrate an evidenced-based approach for the management of LBP. CONCLUSIONS: We systematically reviewed the literature for CPGs' recommendations for the physical rehabilitation management of LBP and synthesized the information through an infographic.

Improving Veteran Access to Integrated Management of Back Pain (AIM-Back): Protocol for an Embedded Pragmatic Cluster-Randomized Trial.

BACKGROUND: 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.

Systematic review of diagnostic accuracy of patient history, clinical findings, and physical tests in the diagnosis of lumbar spinal stenosis.

PURPOSE: To update evidence of diagnostic potential for identification of lumbar spinal stenosis (LSS) based on demographic and patient history, clinical findings, and physical tests, and report posttest probabilities associated with test findings. METHODS: An electronic search of PubMed, CINAHL and Embase was conducted combining terms related to low back pain, stenosis and diagnostic accuracy. Prospective or retrospective studies investigating diagnostic accuracy of LSS using patient history, clinical findings and/or physical tests were included. The risk of bias and applicability were assessed using the Quality Assessment of Diagnostic Accuracy Studies (QUADAS 2) tool. Diagnostic accuracy including sensitivities (SN), specificities (SP), likelihood ratios (+LR and -LR) and posttest probabilities (+PTP and -PTP) with 95% confidence intervals were summarized. RESULTS: Nine studies were included (pooled n = 36,228 participants) investigating 49 different index tests (30 demographic and patient history and 19 clinical findings/physical tests). Of the nine studies included, only two exhibited a low risk of bias and seven exhibited good applicability according to QUADAS 2. The demographic and patient history measures (self-reported history questionnaire, no pain when seated, numbness of perineal region) and the clinical findings/physical tests (two-stage treadmill test, symptoms after a March test and abnormal Romberg test) highly improved positive posttest probability by > 25% to diagnose LSS. CONCLUSION: Outside of one study that was able to completely rule out LSS with no functional neurological changes none of the stand-alone findings were strong enough to rule in or rule out LSS.

Harms and benefits of opioids for management of non-surgical acute and chronic low back pain: a systematic review.

BACKGROUND: Consequences of prescription opioid use involve harms, addiction, tolerance and death. Despite routine prescription, opioids are not recommended for initial intervention by any major multidisciplinary low back pain (LBP) guideline. OBJECTIVE: Our primary purpose was to improve overall understanding of the harms and benefits associated with oral opioid interventions prescribed for treatment of acute or chronic back pain. Our second goal was to evaluate pain intensity and to compare and contrast these data with the harms. Our last objective was to evaluate conflicts of interest among the study authors and the findings. DESIGN/DATA/ELIGIBILITY CRITERIA: Studies incorporating oral prescription opioid management of non-surgical LBP were evaluated. After systematic assessment, no studies that met inclusion included participants with specifically acute LBP. Therefore, extracted data reflects only populations with subacute and chronic LBP. Data on reported harms, severe harms, pain outcomes and withdrawal rates were extracted and meta-analyses were completed for opioid versus placebo trials and opioids versus non-opioid trials. RESULTS: Fourteen studies met inclusion/exclusion requirements. All trials involved short-term management with limited follow-up. A high percentage of harms were identified across most studies. Opioids were not shown to be superior to other medications, and only showed superiority to placebo comparators (at cost of additional harms). CONCLUSION: This review identified trends of higher harms rates and higher percentages of severe harms in opioid arms for the management of subacute and chronic LBP. The majority of trials that demonstrated benefits with opioids also had potential conflicts of interest. Lastly, non-opioid medications demonstrated statistically significant pain improvement compared with opioids. We feel that the results of the trial are supportive of current LBP guidelines and do not condone the initial use of opioids in management of subacute or chronic LBP. TRIAL REGISTRATION NUMBER: CRD42017070914.

Predictors of research productivity among physical therapy programs in the United States: an observational study.

BACKGROUND: This study targeted the association of program characteristics of 203 Doctor of Physical Therapy (DPT) programs in the United States (US) reported by the Commission on Accreditation in Physical Therapy Education (CAPTE) in their 2017 Annual Accreditation Report (AAR) with measures of core faculty research volume. The association of institutional, program, and faculty characteristics of an institution with core faculty research volume was investigated. METHODS: This observational study analyzed data provided in the AAR about program research volume. Predictor variables included institutional, program and faculty characteristics. Research volume was measured as a ratio of 1) number of peer-reviewed publications, 2) National Institutes of Health (NIH) funding, and 3) faculty with grants, per number of core faculty. Research volume was stratified by quartiles and analyzed using logistic regression analyses. The highest 25% were analyzed against the lowest 75%. RESULTS: In the multivariate logistic regression analyses, research Carnegie classification was positively associated with NIH funding (OR = 4.04; 95% CI = 1.92, 8.48) and number of peer reviewed publications (OR = 7.63; 95% CI = 3.39, 17.14). Square footage of research space was positively associated with number of peer reviewed publications (OR = 4.58; 95% CI = 2.08, 10.11). Private status was negatively associated with NIH funding (OR = 0.37; 95% CI = 0.17, 0.83) and faculty holding grants (OR = 0.38; 95% CI = 0.19, 0.76). CONCLUSIONS: There is strong evidence that research culture (e.g., research Carnegie status and dedicated research space) is related to research productivity in DPT programs in the US. Private status was indicative of a non-research intensive environment, which may be reflective of a current trend of small, non-research based private institutions initiating DPT programs.

The Effectiveness of Virtual Reality in Patients With Spinal Pain: A Systematic Review and Meta-Analysis.

BACKGROUND: Virtual reality (VR) technologies have been shown to be beneficial in various areas of health care; to date, there are no systematic reviews examining the effectiveness of VR technology for the treatment of spinal pain. PURPOSE: To investigate the effectiveness of VR technology in the management of individuals with acute, subacute, and chronic spinal pain. METHODS: Six electronic databases were searched until November 2019. Randomized controlled trials (RCTs) assessing the effectiveness of VR were eligible for inclusion. Two independent reviewers extracted the data and assessed the risk of bias for each study and the overall quality of evidence. Mean differences of outcomes were pooled as appropriate using random-effects models. RESULTS: Seven RCTs with high risk of bias met review criteria. Quality of evidence ranged from very low to low quality. In patients with chronic neck pain, VR improved global perceived effect (GPE), satisfaction, and general health at short-term follow-up, as well as general health and balance at intermediate-term follow-up compared to kinematic training. VR improved pain intensity and disability at short-term and long-term follow-up compared to conventional proprioceptive training in patients with chronic neck pain. In patients with either subacute or chronic low back pain (LBP), VR improved pain, disability, and fear of movement compared to lumbar stabilization exercises and improved pain compared to conventional physical therapy (at short-term follow-up). In patients with chronic LBP, VR improved pain compared to lumbar stabilization exercises and improved fear of movement compared to conventional physical therapy (at short-term follow-up). CONCLUSION: VR's potential for improvement in outcomes for spinal pain that demonstrated statistical and/or clinical significance (pain intensity, disability, fear of movement, GPE, patient satisfaction, general health status, and balance) highlights the need for more focused, higher-quality research on the efficacy and effectiveness of VR for treatment of patients with spinal pain.

Comorbidities in the first 2 years after arthroscopic hip surgery: substantial increases in mental health disorders, chronic pain, substance abuse and cardiometabolic conditions.

OBJECTIVES: We aimed to identify the rate of seven comorbidities (mental health disorders, chronic pain, substance abuse disorders, cardiovascular disorders, metabolic syndrome, systemic arthropathy and sleep disorders) that occurred within 2 years after hip arthroscopy. METHODS: Data from individuals (ages 18-50 years) undergoing arthroscopic hip surgery between 2004 and 2013 were collected from the Military Health System (MHS) Data Repository (MDR). The MDR captures all healthcare encounters in all settings and locations for individuals within the MHS. Person-level data over 36 months were pulled and aggregated. Seven comorbidities related to poor outcomes from musculoskeletal disorders (mental health disorders, chronic pain, substance abuse disorders, cardiovascular disorders, metabolic syndrome, systemic arthropathy and sleep disorders) were examined 12 months prior and 24 months after surgery. Changes in frequencies were calculated as were differences in proportions between presurgery and postsurgery. RESULTS: 1870 subjects were identified (mean age 32.24 years; 55.5% men) and analysed. There were statistically significant increases (p<0.001) proportionally for all comorbidities after surgery. Relative to baseline, cases of mental health disorders rose 84%, chronic pain diagnoses increased 166%, substance abuse disorders rose 57%, cardiovascular disorders rose by 71%, metabolic syndrome cases rose 85.9%, systemic arthropathy rose 132% and sleep disorders rose 111%. CONCLUSIONS: Major (potentially 'hidden') clinical comorbidities increased substantially after elective arthroscopic hip surgery when compared with preoperative status. These comorbidities appear to have been overlooked in major studies evaluating the benefits and risks of arthroscopic hip surgery. LEVEL OF EVIDENCE: Prognostic, level III.

Differences in Characteristics and Downstream Drug Use Among Opioid-Naïve and Prior Opioid Users with Low Back Pain.

BACKGROUND: Recent clinical practice guidelines have suggested conservative treatment approaches, including physical therapy, are indicated as first-line treatment for patients with low back pain (LBP); however, LBP continues to be managed with opioids, despite decreases in function, morbidity, and insignificant improvements in pain. OBJECTIVE: The primary purpose was to compare characteristics and downstream medication use between patients with LBP with prior opioid exposure vs. those who were opioid-naïve. The secondary purpose was to explore the role of prior opioid use by LBP disability. METHODS: Seven hundred and nine participants in a LBP self-management class were evaluated utilizing self-report data at baseline and longitudinal claims data from the Military Health System Data Repository. Participants were dichotomized into opioid-naïve and prior opioid use groups and then further divided into low and high disability groups based on Oswestry Disability Index (ODI) scores. Patient characteristics, comorbidities, and medication use were compared between groups. RESULTS: Prior opioid users had significantly higher baseline ODI and Fear Avoidance Beliefs Questionnaire physical activity subscale and work subscale scores as well as pre-index instances of mental health disorders, chronic pain, and insomnia than opioid-naïve individuals. Prior opioid users filled significantly more pain medication prescriptions in the year after the index date than did opioid-naïve individuals. Prior opioid users were significantly more likely to be taking opioids at 1 year after the index date, regardless of disability level. CONCLUSION: In patients presenting with LBP, prior opioid exposure appears to be related to increased analgesic use (opioid and non-opioid) and longitudinal analgesic utilization at 1 year after the index date.

Red flag screening for low back pain: nothing to see here, move along: a narrative review.

Screening for red flags in individuals with low back pain (LBP) has been a historical hallmark of musculoskeletal management. Red flag screening is endorsed by most LBP clinical practice guidelines, despite a lack of support for their diagnostic capacity. We share four major reasons why red flag screening is not consistent with best practice in LBP management: (1) clinicians do not actually screen for red flags, they manage the findings; (2) red flag symptomology negates the utility of clinical findings; (3) the tests lack the negative likelihood ratio to serve as a screen; and (4) clinical practice guidelines do not include specific processes that aid decision-making. Based on these findings, we propose that clinicians consider: (1) the importance of watchful waiting; (2) the value-based care does not support clinical examination driven by red flag symptoms; and (3) the recognition that red flag symptoms may have a stronger relationship with prognosis than diagnosis.

Leveraging healthcare utilization to explore outcomes from musculoskeletal disorders: methodology for defining relevant variables from a health services data repository.

BACKGROUND: Large healthcare databases, with their ability to collect many variables from daily medical practice, greatly enable health services research. These longitudinal databases provide large cohorts and longitudinal time frames, allowing for highly pragmatic assessment of healthcare delivery. The purpose of this paper is to discuss the methodology related to the use of the United States Military Health System Data Repository (MDR) for longitudinal assessment of musculoskeletal clinical outcomes, as well as address challenges of using this data for outcomes research. METHODS: The Military Health System manages care for approximately 10 million beneficiaries worldwide. Multiple data sources pour into the MDR from multiple levels of care (inpatient, outpatient, military or civilian facility, combat theater, etc.) at the individual patient level. To provide meaningful and descriptive coding for longitudinal analysis, specific coding for timing and type of care, procedures, medications, and provider type must be performed. Assumptions often made in clinical trials do not apply to these cohorts, requiring additional steps in data preparation to reduce risk of bias. The MDR has a robust system in place to validate the quality and accuracy of its data, reducing risk of analytic error. Details for making this data suitable for analysis of longitudinal orthopaedic outcomes are provided. RESULTS: Although some limitations exist, proper preparation and understanding of the data can limit bias, and allow for robust and meaningful analyses. There is the potential for strong precision, as well as the ability to collect a wide range of variables in very large groups of patients otherwise not captured in traditional clinical trials. This approach contributes to the improved understanding of the accessibility, quality, and cost of care for those with orthopaedic conditions. CONCLUSION: The MDR provides a robust pool of longitudinal healthcare data at the person-level. The benefits of using the MDR database appear to outweigh the limitations.

Variables Describing Individuals With Improved Pain and Function With a Primary Complaint of Low Back Pain: A Secondary Analysis.

OBJECTIVES: The purpose of this study was to identify descriptive factors in individuals with a primary complaint of low back pain (LBP) associated with improved pain and function after receiving physical therapy for LBP with or without manual therapy and exercise directed at the femoroacetabular joints. METHODS: Participants were enrolled in a randomized clinical trial investigating physical therapy interventions for their LBP, with or without interventions directed at the femoroacetabular joints (hips). A participant was deemed recovered if all of the following were met: Numeric Pain Rating Scale (NPRS) score of ≤2 points, ≤10% on the modified Oswestry Disability Index at discharge, and a global rating of change score of +4 at both 2 weeks and discharge. Logistic regression modelling determined descriptor variables that best predicted treatment recovery. RESULTS: Data from 90 participants were included in the analysis, with 44% (n = 40) achieving recovery by discharge from physical therapy (average 7.95 [±4.68]) visits. The variables of concurrent hip problems, lower body mass index ≤25.4, an irritable condition, and a baseline NPRS score of 4 points or less were retained in the final model (R2 = .384). Having a concurrent hip problem had the highest odds of achieving recovery in the model (odds ratio: 5.34, 95 % confidence interval: 1.31-21.8). CONCLUSIONS: The findings for the patients in this study suggest that those with a concurrent hip problem, a lower body mass index, irritable symptoms, and a baseline NPRS score of 4 points or less were associated with greater odds of achieving recovery with multimodal physical therapy interventions. Further research should continue to investigate the interplay between the lumbar spine and hip joints.

Does shared decision making results in better health related outcomes for individuals with painful musculoskeletal disorders? A systematic review.

Background: Shared Decision-Making (SDM) is a dynamic process by which the health care professional and the patient influence each other in making health-related choices or decisions. SDM is strongly embedded in today's health care approaches, and is advocated as an ideal model since it renders individuals more control towards the health care they choose to receive, and has been shown to improve patient outcomes. Objectives: The goal of this systematic review was to investigate the added-value of SDM on clinical health-related outcomes in patients with a variety of musculoskeletal conditions. Data sources: PubMed and CINAHL. Study selection: PRISMA guidelines were followed for this review. To be considered for review, the study had to meet all the following criteria: (1) prospective studies that involved treatment decision-making; (2) randomized controlled trial design; (3) involving patients faced with having to make a treatment decision; (4) comparing SDM with a control intervention and (5) including one or more of the following outcome measures: well-being, costs, health-related pain or disability measures, or quality of life. Study appraisal: A priori, we determined to perform methodological quality assessment using the Cochrane Risk of Bias tool for randomized controlled trials. Results: We did not find a single study that looked at the true effect of SDM on patient reported outcomes in a population with musculoskeletal pain. Conclusion: For the management of painful musculoskeletal conditions, in the light of the current evidence (none), we estimate that it would be wise to explore the effectiveness of SDM before forcing its large-scale implementation in rehabilitation.
