The Relationship of PROMIS Pain Interference and Physical Function Scales

Understanding the Experiences of Patients With Pancreatic Cancer: Quantitative Analysis of the Pancreatic Cancer Action Network Patient Registry

Background

The Pancreatic Cancer Action Network (PanCAN) established its Patient Registry to gather real-world data from patients with pancreatic cancer and their caregivers, related to their diagnosis, symptoms and symptom management, treatments, and more. Results from version 2 of the PanCAN Registry are presented here.

Objective

We sought to gather and evaluate patient-reported outcomes data inputted into the PanCAN Patient Registry from December 2020 to January 2024. Statistical analyses were used to identify findings from a relatively small sample size (271 participants, as defined by people who filled out the Basics survey of the PanCAN Registry).

Methods

Participation in the PanCAN Patient Registry was voluntary, and participants filled out an electronic consent form before joining the registry. Participants were identified through the PanCAN Patient Services Help Line or navigated to the registry directly via the PanCAN website. Data analysis took place via bivariate analysis using the chi-square test for categorical variables. Statistical significance was defined as a P value of <.05, with P values between .05 and .1 considered marginally significant, and P values >.1 considered insignificant.

Results

Pain was reported by 186 out of the 207 (89.9%) PanCAN Patient Registry participants who filled out the pain-related questions in the General Assessment survey. We observed a marginally significant (P=.06) difference between the reporting of pain by patients aged younger than 65 years (86/92, 93.5%) and those aged 65 years or older (66/78, 84.6%). Depression was also a common condition experienced by patients with pancreatic cancer, with 64/103 (62.1%) indicating that they were experiencing or had experienced depression during the course of their illness. A trend suggested that depression was more frequently reported among the subset of patients who also reported pain (53/80, 66.3%) compared with those who did not report pain (5/13, 38.5%; P=.07).

Conclusions

The use of patient-reported outcomes and real-world data for patients with pancreatic cancer has the potential to have direct impact on clinical practice. Through a relatively small sampling of patients, trends were identified that suggest a higher reporting of pain amongst patients in a younger age group as well as concurrence of pain and depression. These findings underscore the importance of a multidisciplinary team of health care professionals addressing patients' needs beyond the treatment of their cancer.

Preoperative Factors Associated With Worse PROMIS Pain Interference 2 Years After Hand and Wrist Surgery

BACKGROUND

The purpose of this study was to identify preoperative factors associated with worse postoperative Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference (PI) scores 2 years after hand and wrist surgery. We hypothesized that older age, more comorbidities, increased substance use, and lower socioeconomic status would correlate with worse 2-year PROMIS PI scores.

METHODS

This study was a retrospective review of prospectively acquired data on 253 patients. Surveys were administered within 1 week of surgery and 2 years postoperatively. Bivariate and multivariable analyses were conducted to identify significant predictors of worse 2-year PROMIS PI scores and change in PROMIS PI scores.

RESULTS

Older age, higher body mass index, more comorbidities, lower preoperative expectations, more prior surgeries, unemployment, smoking, higher American Society of Anesthesiologists (ASA) score, and multiple other socio-demographic factors were correlated with worse 2-year PROMIS PI scores (P ≤ .018). Similar factors were also correlated with less improvement in 2-year PROMIS PI scores (P ≤ .048). Worse scores on all preoperative patient-reported outcome measures correlated with worse 2-year PROMIS PI scores (P ≤ .007). Multivariable analysis identified smoking history, less frequent alcohol consumption, worse preoperative PROMIS social satisfaction and Numeric Pain Scale whole body scores, and higher ASA scores as independent predictors of worse 2-year PROMIS PI. The same factors in addition to better baseline PROMIS PI were predictive of less improvement in 2-year PROMIS PI.

CONCLUSION

Numerous preoperative factors were predictive of worse postoperative 2-year PROMIS PI and less improvement in 2-year PROMIS PI for patients undergoing hand and wrist surgery.

Evaluation of fluoroscopically guided transforaminal epidural steroid injections for cervical radiculopathy utilizing patient reported outcome measurement information system as an outcome measure

Background

Cervical radiculopathy is a common cause of pain. For patients who fail conservative management, a transforaminal epidural steroid injection (TFESI) is an accepted intervention and alternative to decompression surgery.

Objective

The purpose of this study was to evaluate the therapeutic effect of TFESIs for patients with cervical radiculopathy.

Methods

Adult patients treated at a multidisciplinary, tertiary academic spine center with cervical radicular pain and MRI evidence of corroborative cervical spondylotic foraminal stenosis and who had failed at least 6 weeks of conservative management consisting of medication and physical rehabilitation were included in this study. Patient Reported Outcome Measurement Information System (PROMIS) domains of Physical Function (PF) v1.2/v2.0 and Pain Interference (PI) v1.1 were collected at baseline and at 3-, 6-, and 12-month follow-up visits. Statistical analysis comparing baseline score with follow-up post-procedural PROMIS scores was performed. The percentage of patients who reported improvement exceeding the minimal clinically important difference was calculated for survey responders and for the worst case scenario.

Results

87 patients met inclusion criteria. PROMIS PI at 3-, 6-, and 12-months follow-up statistically improved by 2.2 (95 % confidence interval [CI] 2.1-2.4, p = 0.02), 2.3 (95 % CI 2.1-2.5, p = 0.03), and 2.7 (95 % CI 2.5-3.0, p = 0.03) points, respectively. Follow-up PROMIS PF score did not significantly differ from baseline scores. The percentage of patients that exceeded MCID thresholds of clinical significance was 59 % (95 % CI 47%-70 %) at 3-months, 52 % (95 % CI 41%-63 %) at 6-months, and 60 % (95 % CI 50%-72 %) at 12-months. Worst case scenario analysis demonstrated that 51 % (95 % CI 39%-62 %) of patients exceeded the MCID thresholds at 3-months, 32 % (95 % CI 22%-43 %) at 6-months, and 23 % (95 % CI 13%-33 %) at 12-months.

Conclusions

Our study demonstrated that TFESI leads to a long-term improvement up to a year in pain for patients with cervical radiculopathy.

The Mediating Role of Physical Function on the Self-Reported Pain and Cognitive Function Association

BACKGROUND/OBJECTIVES

Studies that have investigated the relationship between pain intensity and interference and cognitive function have failed to fully consider the role physical function may play in this relationship. Therefore, the purpose of this study was to examine the mediating role of physical function in the relationship between self-reported pain intensity and interference and cognitive function in middle-to-older aged adults with knee pain.

METHODS

Middle-to-older aged participants with knee pain (n = 202) completed the Graded Chronic Pain Scale to assess pain intensity and interference, the Short Performance Physical Battery to assess lower-extremity physical function, and the Montreal Cognitive Assessment to assess global cognitive function. Linear regression-based mediation analyses were used to assess associations between pain intensity and interference and cognitive function, with lower-extremity physical function as the mediator.

RESULTS

The direct relationship between pain intensity and cognitive function was significant (β = -0.269, p < .001) and remained significant when physical function was included as a mediator (c'=-0.0854, p = .003). The direct relationship between pain interference and cognitive function was also significant (β = -0.149, p = .023) but was attenuated when physical function was included as a mediator (c'=-0.0100, p = .09).

CONCLUSION

Physical function partially mediated the relationship between pain intensity and cognitive function and fully mediated the relationship between pain interference and cognitive function. Significance/Implications: Higher levels of pain intensity and interference may lead to worse cognitive function when physical function is also impaired. Improving physical function may improve cognitive function in those with pain.

Noninvasive targeted modulation of pain circuits with focused ultrasonic waves

ABSTRACT

Direct interventions into deep brain circuits constitute promising treatment modalities for chronic pain. Cingulotomy and deep brain stimulation targeting the anterior cingulate cortex have shown notable improvements in the unpleasantness of pain, but these interventions require brain surgeries. In this study, we have developed an approach that can modulate this deep brain affective hub entirely noninvasively, using low-intensity transcranial-focused ultrasound. Twenty patients with chronic pain received two 40-minute active or sham stimulation protocols and were monitored for one week in a randomized crossover trial. Sixty percent of subjects experienced a clinically meaningful reduction of pain on day 1 and on day 7 following the active stimulation, while sham stimulation provided such benefits only to 15% and 20% of subjects, respectively. On average, active stimulation reduced pain by 60.0% immediately following the intervention and by 43.0% and 33.0% on days 1 and 7 following the intervention. The corresponding sham levels were 14.4%, 12.3%, and 6.6%. The stimulation was well tolerated, and no adverse events were detected. Side effects were generally mild and resolved within 24 hours. Together, the direct, ultrasonic stimulation of the anterior cingulate cortex offers rapid, clinically meaningful, and durable improvements in pain severity.

Assessing the measurement properties of PROMIS Computer Adaptive Tests, short forms and legacy patient reported outcome measures in patients undergoing total hip arthroplasty

BACKGROUND

The commonly used ('legacy') PROMs evaluating outcomes of total hip arthroplasty (THA), have several limitations regarding their measurement properties and interpretation of scores. One innovation in PROMs is the use of Computerized Adaptive Testing (CAT). The Patient-Reported Outcomes Measurement Information System (PROMIS®) is a validated system of CATs. The aim of this study was to assess the measurement properties of PROMIS and legacy instruments in patients undergoing THA.

METHODOLOGY

Patients in this multicenter study filled out a questionnaire twice, including Dutch-Flemish PROMIS v1.2 Physical Function (PROMIS-PF) and v1.1 Pain Interference (PROMIS-PI) CATs and short forms, PROMIS v1.0 Pain Intensity, and legacy PROMs (Hip disability and Osteoarthritis Outcome Score (HOOS), HOOS-Physical function Shortform (HOOS-PS), Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Oxford Hip Score (OHS), and two numeric rating scales measuring pain). The reliability, measurement precision (Standard Error of Measurement (SEM)), smallest detectable change (SDC), and burden of PROMIS instruments were presented head-to-head to legacy PROMs. Furthermore, construct validity was assessed.

RESULTS

208 patients were included. All instruments had a sufficient test-retest reliability (range ICC: 0.83-0.96). The SEM of PROMIS CATs and short forms ranged from 1.8 to 2.2 T-score points, the SEM of legacy instruments 2.6-11.1. The SDC of PROMIS instruments ranged from 2.1 to 7.3 T-score points, the SDC of legacy instruments 7.2-30.9. The construct validity of PROMIS CAT and short forms were found sufficient, except for the PROMIS-PI short form. The burden of PROMIS CATs was smaller than PROMIS short forms (range 4.8-5.2 versus 8-20 items, respectively). The burden of legacy instruments measuring physical functioning ranged from 5 to 40 items.

CONCLUSIONS

The PROMIS-PF is less burdensome, with high measurement precision, and almost no minimal or maximal scores, and an equal reliability compared to legacy instruments measuring physical functioning in patients undergoing THA. The PROMIS Pain Intensity 1a is comparable to the legacy pain instruments in terms of burden, reliability and SDC. Measuring the construct Pain Interference may not have additional value in this population because of its high correlation with instruments measuring physical functioning. The SDC values presented in this study can be used for individual patient monitoring.

Vulnerability Factors, Adjustment, and Opioid Misuse in Chronic Noncancer Pain Individuals

Several person variables predate injury or pain onset that increase the probability of maladjustment to pain and opioid misuse. The aim of this study was to evaluate the role of 2 diathesis variables (impulsiveness and anxiety sensitivity [AS]) in the adjustment of individuals with chronic noncancer pain and opioid misuse. The sample comprised 187 individuals with chronic noncancer pain. The hypothetical model was tested using correlation and structural equation modeling analyses. The results show a significant association between impulsiveness and AS and all the maladjustment variables, and between impulsiveness and AS and opioid misuse and craving. However, although the correlation analysis showed a significant association between adjustment to pain and opioid misuse, the structural equation modeling analysis showed a nonsignificant association between them (as latent variables). The findings support the hypothesis that both impulsiveness and AS are vulnerability factors for maladaptive adjustment to chronic pain and opioid misuse. PERSPECTIVE: This article adds to the empirical literature by including AS and impulsiveness as antecedent variables in a model of dual vulnerability to chronic pain maladjustment and opioid misuse. The findings suggest the potential utility of assessing both factors in individuals in the first stages of chronic pain.

Do Maladaptive Imaging Beliefs Predict Self-Reported Pain Interference and Physical Function in Patients With Musculoskeletal Disorders?

OBJECTIVE: To determine if maladaptive imaging beliefs correlated with, and predicted pain interference and physical function outcomes in people with musculoskeletal pain disorders. DESIGN: A prospective cohort study of patients with musculoskeletal disorders receiving outpatient physical therapy from April 2022 to August 2023. METHODS: Four questions about imaging were asked to assess maladaptive beliefs, the need to rule out serious conditions, guide treatment, determine diagnosis, and validate symptoms. Correlations with beliefs and outcomes were assessed using Kendall's tau rank and Spearman's rho correlation coefficients. Generalized linear models determined if these beliefs predicted outcomes at baseline and 6 weeks. RESULTS: The cohort included 152 participants (mean [standard deviation] age: 56.13 [15.13]; 32.2% male). Maladaptive imaging beliefs correlated positively with pain interference and negatively with physical function. The need to rule out serious conditions and validate symptoms correlated with pain interference (range: τb = 0.17, 0.20; P = .003, .0121) and physical function (range: ρ = -0.22, -0.22; P = .006, .008). All but 1 belief correlated with pain interference (range: τb = 0.19, 0.24; P<.001, .004) and physical function (range: ρ = -0.26, -0.21; P = .001, .009) at 6 weeks. Each additional belief slightly increased pain interference at 6 weeks (β = 0.01; 95% CI: 0.001, 0.03; P = .04) and lowered physical function at both baseline (β = -0.97; 95% CI: -1.66, -0.28; P = .01) and 6 weeks (β = -0.76; 95% CI: -1.37, -0.15; P = .02). CONCLUSION: Maladaptive imaging beliefs were significantly (albeit weakly) correlated with pain and physical function. Each additional maladaptive imaging belief increased pain interference at 6 weeks and lowered physical function at baseline and 6 weeks. Beliefs about the necessity of imaging to properly manage musculoskeletal disorders may influence outcomes. J Orthop Sports Phys Ther 2024;54(9):1-10. Epub 5 July 2024. doi:10.2519/jospt.2024.12625.

Evaluation of Fluoroscopically Guided Transforaminal Selective Nerve Root Sleeve Injections for Lumbar Spinal Stenosis With Radiculopathy Utilizing Patient Reported Outcome Measurement Information System as an Outcome Measure

OBJECTIVE

To evaluate the therapeutic effect of transforaminal selective nerve root sleeve injections (TFSNRIs) in a specific subset of patients with clinical symptoms and presentation consistent with spinal stenosis.

DESIGN

Retrospective review.

SETTING

Tertiary academic spine center.

PARTICIPANTS

A total of 176 patients with radicular leg pain with or without low back pain as well as ≥3 clinical features of spinal stenosis and corroborative radiographic features of spinal stenosis on lumbar spine magnetic resonance imaging without confounding spinal pathology (N=176).

INTERVENTIONS

Fluoroscopically guided transforaminal selective nerve root sleeve injections.

MAIN OUTCOME MEASURES

Patient Reported Outcome Measurement Information System (PROMIS) Physical Function (PF) v1.2/v2.0, Pain Interference (PI) v1.1, and PROMIS (D) v1.0 were collected at baseline and post-procedure short term (<3-months) and long-term (6-12 month) follow-up. Statistical analysis comparing baseline and postprocedural PROMIS scores was performed. Differences were compared with previously established minimal clinically important differences in the spine population.

RESULTS

For patients with spinal stenosis treated with TFSNRI, no statistically significant improvement was observed short- and long-term follow-up in PROMIS PF (P=.97, .77) and PROMIS Depression (P=.86, .85) scores. At short-term follow-up, PROMIS PI scores did significantly improve (P=.01) but the average difference of pre- and post-procedure scores did not reach clinical significance. No significant difference in PROMIS PI was noted at long-term follow-up (.75).

CONCLUSIONS

Although a statistically significant difference was observed for improvement in pain, in this retrospective study, TFSNRI did not provide clinically significant improvement in patients' function, pain, or depression for lumbar spinal stenosis at short- and long-term follow-up.

The Relationship Between Preoperative Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference and Pain Intensity Scores and Early Postoperative Pain and Opioid Consumption After Lumbar Fusion

Background The Patient-Reported Outcomes Measurement Information System (PROMIS) pain interference and pain intensity measures quantify separate dimensions of pain from the patient's perspective. This study aimed to assess differences in these outcomes and to evaluate whether baseline PROMIS pain scores could be used as a leading indicator of increased pain and opioid consumption during early recovery after lumbar fusion. Methods A retrospective review of 199 consecutive patients undergoing posterolateral fusion (PLF) at a single institution was performed. All patients underwent one to three level lumbar PLF and preoperatively completed the PROMIS pain intensity and PROMIS pain interference measures. Multivariate linear regression was used to assess the relationship between preoperative PROMIS scores and postoperative pain numeric rating scale (NRS) and oral morphine milligram equivalents (OMME) by day after controlling for age, sex, and body mass index (BMI). Results In comparison to patients with the lowest preoperative pain intensity scores, those with the highest scores required significantly more OMME on postoperative day (POD) zero and one (both p<0.05) and had higher pain NRS on POD one (p=0.02). Patients with the highest pain interference scores reported higher pain NRS on POD zero (p=0.02) but required similar OMME at all time points. After controlling for age, sex, and BMI, each one-point increase in preoperative PROMIS pain interference scores was associated with increased OMME on POD zero (β=0.29, p=0.04) and POD one (β=0.64, p=0.03). Conclusions Patients with high pain intensity reported higher levels of pain and required more opioids during the first 24 hours postoperatively, while those with high pain interference reported higher levels of pain on the day of surgery but utilized similar amounts of opioids. After risk adjustment, increased baseline PROMIS pain interference scores - but not pain intensity - were associated with increased opioid use. These results suggest that both measures should be considered when identifying patients at risk for increased pain and opioid consumption after PLF.

Pain Scales: What Are They and What Do They Mean

PURPOSE OF REVIEW

It is essential to have validated and reliable pain measurement tools that cover a wide range of areas and are tailored to individual patients to ensure effective pain management. The main objective of this review is to provide comprehensive information on commonly used pain scales and questionnaires, including their usefulness, intended purpose, applicability to different patient populations, and associated advantages and disadvantages.

RECENT FINDINGS

Acute pain questionnaires typically focus on measuring the severity of pain and the extent of relief achieved through interventions. Chronic pain questionnaires evaluate additional aspects such as pain-related functional limitations, psychological distress, and psychological well-being. The selection of an appropriate pain scale depends on the specific assessment objectives. Additionally, each pain scale has its strengths and limitations. Understanding the differences among these pain scales is essential for selecting the most appropriate tool tailored to individual patient needs in different settings.

CONCLUSION

Medical professionals encounter challenges in accurately assessing pain. Physicians must be familiar with the different pain scales and their applicability to specific patient population.

Construct validity of the Hungarian Version of the Patient-Reported Outcomes Measurement Information System-29 Profile Among Patients with Low Back Pain

OBJECTIVE

We aim to evaluate the psychometric properties of the Hungarian version of the patient-reported outcomes measurement information system (PROMIS)-29 profile domains among patients with chronic low back pain.

METHODS

We used a convenience, cross-sectional sampling of patients recruited at our neurosurgical institution. The participants completed paper-pencil version of the PROMIS-29 profile in addition to validated legacy questionnaires, including the Oswestry disability index, Research and Development Corporation 36-item short-form survey, 7-item general anxiety disorder scale, 9-item patient health questionnaire. Reliability was evaluated by calculating the internal consistency (Cronbach's α). Test-retest reliability was assessed using the intraclass correlation coefficient. The structural validity of PROMIS-29 was assessed using a confirmatory factor analysis. Construct validity was assessed by evaluating convergent and discriminant validity using Spearman's rank correlation. To further corroborate the construct validity, we also performed known-group comparisons.

RESULTS

The mean age of the 131 participants was 54 ± 16 years. Of the 131 patients, 62% were women. The internal consistency of each PROMIS domain was high (Cronbach's α >0.89 for all). The test-retest reliability was excellent (intraclass correlation >0.97). The confirmatory factor analysis showed good structural validity (comparative fit index >0.96; standardized root mean square residual <0.026 for all domains). All measured PROMIS scores correlated strongly with the scores obtained using the corresponding primary legacy instrument, indicating excellent convergent validity. The known-group comparisons demonstrated differences as hypothesized.

CONCLUSIONS

We present data supporting the validity and reliability of the Hungarian PROMIS-29 profile short forms for patients with low back pain. This instrument will be useful for research and clinical applications in spine care.

Facilitators and barriers to employment for people with adult-onset physical disabilities: results from a U.S.A. survey

BACKGROUND

Employment has long been an area of concern for people with disabilities. National samples in the United States are needed to understand the experiences of people with disabilities related to employment.

OBJECTIVES

(1) Describe and evaluate associations between personal and health-related factors with employment after disability, and (2) describe and evaluate associations between facilitators, barriers, and work-related external factors with maintaining a longest held job after disability.

METHODS

We recruited a national sample of people with physical disabilities from panels assembled by a United States market research organization; by selection, 1309 were working and 491 were not. We evaluated the likelihood of employment and maintaining employment after disability onset using Poisson regression. Model 1 evaluated factors associated with employment; Model 2 evaluated factors associated with maintained employment.

RESULTS

Model 1: Older age, decreased ability to pay bills on time, and assistive device use were associated with decreased likelihood of employment after disability onset. Non-Black minority identification, fatigue, and higher physical function were associated with increased likelihood of employment. For Model 2, the likelihood of maintaining a longest held job was associated with acquiring a disability at work, receipt of job accommodations, valuing opportunities for advancement and health benefits, having a helpful living situation, and helpful human resource attitudes. Decreased likelihood of maintaining a longest held job after disability onset was associated with job dissatisfaction and supervisors' attitudes.

CONCLUSIONS

This work highlights opportunities for employers to focus efforts on job accommodations and support in the maintenance of employment after disability.

Pre-Diagnosis Pain in Patients With Pancreatic Cancer Signals the Need for Aggressive Symptom Management

OBJECTIVE

This study assessed the impact of pancreatic cancer (PC) pain on associated symptoms, activities, and resource utilization from 2016 to 2020 in an online patient registry.

PATIENTS AND METHODS

Responses from PC patient volunteers (N = 1978) were analyzed from online surveys in a cross-sectional study. Comparisons were performed between PC patient groups reporting, (1) the presence vs. absence of pre-diagnosis PC pain, (2) high (4-8) vs. low (0-3) pain intensity scores on an 11-point numerical rating scale (NRS), and (3) year of PC diagnosis (2010-2020). Descriptive statistics and all bivariate analyses were performed using Chi-square or Fisher's Exact tests.

RESULTS

PC pain was the most frequently reported pre-diagnosis symptom (62%). Pre-diagnostic PC pain was reported more frequently by women, those with a younger age at diagnosis, and those with PC that spread to the liver and peritoneum. Those with pre-diagnostic PC pain vs. those without reported higher pain intensities (2.64 ± 2.54 vs.1.56 ± 2.01 NRS mean ± SD, respectively, P = .0039); increased frequencies of post-diagnosis symptoms of cramping after meals, feelings of indigestion, and weight loss (P = .02-.0001); and increased resource utilization in PC pain management: (ER visits N = 86 vs. N = 6, P = .018 and analgesic prescriptions, P < .03). The frequency of high pain intensity scores was not decreased over a recent 11-year span.

CONCLUSIONS

PC pain continues to be a prominent PC symptom. Patients reporting pre-diagnosis PC pain experience increased GI metastasis, symptoms burden, and are often undertreated. Its mitigation may require novel treatments, more resources dedicated to ongoing pain management and surveillance to improve outcomes.

When Musculoskeletal Clinicians Respond to Empathetic Opportunities, do Patients Perceive Greater Empathy?

BACKGROUND

Patient use of verbal and nonverbal communication to signal what is most important to them can be considered empathetic opportunities. Orthopaedic surgeons may have mixed feelings toward empathetic opportunities, on one hand wanting the patient to know that they care, and on the other hand fearing offense, prolonged visit duration, or discussions for which they feel ill prepared. Evidence that action about empathetic opportunities does not harm the patient's experience or appreciably prolong the visit could increase the use of these communication tactics with potential for improved experience and outcomes of care.

QUESTIONS/PURPOSES

Using transcripts from musculoskeletal specialty care visits in prior studies, we asked: (1) Are there factors, including clinician attentiveness to empathetic opportunities, associated with patient perception of clinician empathy? (2) Are there factors associated with the number of patient-initiated empathetic opportunities? (3) Are there factors associated with clinician acknowledgment of empathetic opportunities? (4) Are there factors associated with the frequency with which clinicians elicited empathetic opportunities?

METHODS

This study was a retrospective, secondary analysis of transcripts from prior studies of audio and video recordings of patient visits with musculoskeletal specialists. Three trained observers identified empathetic opportunities in 80% (209 of 261) of transcripts of adult patient musculoskeletal specialty care visits, with any uncertainties or disagreements resolved by discussion and a final decision by the senior author. Patient statements considered consistent with empathetic opportunities included relation of emotion, expression of worries or concerns, description of loss of valued activities or loss of important roles or identities, relation of a troubling psychologic or social event, and elaboration on daily life. Clinician-initiated empathetic opportunities were considered clinician inquiries about these factors. Clinician acknowledgment of empathetic opportunities included encouragement, affirmation or reassurance, or supportive statements. Participants completed post-visit surveys of perceived clinician empathy, symptoms of depression, and health anxiety. Factors associated with perceived clinician empathy, number of empathetic opportunities, clinician responses to these opportunities, and the frequency with which clinicians elicited empathetic opportunities were sought in bivariate and multivariable analyses.

RESULTS

After controlling for potentially confounding variables such as working status and pain self-efficacy scores in the multivariable analysis, no factors were associated with patient perception of clinician empathy, including attentiveness to empathetic opportunities. Patient-initiated empathetic opportunities were modestly associated with longer visit duration (correlation coefficient 0.037 [95% confidence interval 0.023 to 0.050]; p < 0.001). Clinician acknowledgment of empathetic opportunities was modestly associated with longer visit duration (correlation coefficient 0.06 [95% CI 0.03 to 0.09]; p < 0.001). Clinician-initiated empathetic opportunities were modestly associated with younger patient age (correlation coefficient -0.025 [95% CI -0.037 to -0.014]; p < 0.001) and strongly associated with one specific interviewing clinician as well as other clinicians (correlation coefficient -1.3 [95% CI -2.2 to -0.42]; p = 0.004 and -0.53 [95% CI -0.95 to -0.12]; p = 0.01).

CONCLUSION

Musculoskeletal specialists can respond to empathic opportunities without harming efficiency, throughput, or patient experience.

CLINICAL RELEVANCE

Given the evidence that patients prioritize feeling heard and understood, and evidence that a trusting patient-clinician relationship is protective and healthful, the results of this study can motivate specialists to train and practice effective communication tactics.

Group differences and associations between patient-reported outcomes and physical characteristics in chronic low back pain patients and healthy controls

BACKGROUND

Patients with chronic low back pain can exhibit altered slower gait, poor balance, and lower strength/power, and psychological dysfunctions such as pain catastrophizing and fear of movement. Few studies have investigated the relationships between physical and psychological dysfunctions. This study examined associations between patient-reported outcomes (pain interference, physical function, central sensitization, and kinesiophobia) and physical characteristics (gait, balance, and trunk sensorimotor characteristics).

METHODS

Laboratory testing included a 4-m walk, balance, and trunk sensorimotor testing with 18 patients and 15 controls. Gait and balance were collected with inertial measurement units. Isokinetic dynamometry measured trunk sensorimotor characteristics. Patient-reported outcomes included PROMIS Pain Interference / Physical Function, Central Sensitization Inventory, and Tampa Scale of Kinesiophobia. Independent t-tests or Mann-Whitney U tests were used to compare between groups. Additionally, Spearman's rank correlation coefficient (r_s) established associations between physical and psychological domains, and Fisher z-tests compared correlation coefficient values between groups (significance P < 0.05).

FINDINGS

The patient group had worse tandem balance and all patient-reported outcomes (P < 0.05) while no group differences were observed in gait and trunk sensorimotor characteristics. There were significant correlations between worse central sensitization and poor tandem balance (r_s = 0.446-0.619, P < 0.05) and lower peak force and rate of force development (r_s = -0.429-0.702, P < 0.05).

INTERPRETATION

Observed group differences in tandem balance agree with previous studies, indicating impaired proprioception. The current findings provide preliminary evidence that balance and trunk sensorimotor characteristics were significantly associated with patient-reported outcomes in patients. Early and period screening could help clinicians further categorize patients and develop objective treatment plans.

Higher Grit Scores Are Associated With Earlier Increases in Knee Flexion Following Anterior Cruciate Ligament Reconstruction With Meniscus Repair in Pediatric Patients

BACKGROUND

The Grit Scale is used to measure grit, defined by Duckworth and colleagues as the disposition to show perseverance and passion for long-term goals. It has been shown that psychological factors like motivation, coachability, and coping with adversity are correlated with faster readiness for return to sport (RTS) in patients undergoing anterior cruciate ligament reconstruction (ACLR). This study investigates the association between pediatric patients' baseline grit scores and; preoperative Patient-reported Outcomes Measurement Information System (PROMIS) Pain scores and the recovery of range of motion (ROM) after ACLR. The investigators hypothesized that higher preoperative grit scores would predict lower preoperative pain scores and earlier return of knee ROM in patients undergoing ACLR.

METHODS

This is a retrospective cohort study. Pediatric patients who underwent primary ACLR were assigned the pediatric Grit Scale. Patients were subdivided by meniscal procedures due to differences in postoperative protocols. ACLR alone or with meniscectomy (ACLR ± meniscectomy) were grouped together and ACLR with meniscal repair (ACLR + meniscus repair) represented the other cohort. Patients above the 50th grit percentile were considered "high grit". Patients below the 50th percentile were considered "low grit". Baseline PROMIS pain intensity and interference were collected. ROM was compared by grit cohort using the Mann-Whitney U test with a significance threshold of P ≤ 0.05.

RESULTS

A total of 58 patients undergoing ACLR were analyzed: 20 ACLR ± meniscectomy and 38 ACLR + meniscus repair. The mean age was 15.0 ± 2.1 years with 41.4% of participants identifying as females. No significant difference was noted between baseline PROMIS pain intensity and interference and grit score ( P = 0.82, P = 0.91, respectively). Three months postoperatively, for those in the ACLR + meniscus repair cohort, low grit ROM was 130 degrees (interquartile range = 10 degrees), whereas high grit ROM was 135 degrees (interquartile range = 8 degrees) ( P = 0.006).

CONCLUSIONS

This study found no differences in pain scores at presentation between grit cohorts but found that patients with grit scores below the 50th percentile undergoing ACLR + meniscus repair have 5 degrees less total ROM at 3 months compared with those with high grit scores. Quicker ROM recovery in patients with high grit may be a leading indicator of these patients' likelihood to achieve other postoperative milestones and meet criteria for RTS more quickly; the relationship between grit and readiness for RTS should be further investigated.

Patient-reported Outcomes of Adolescents Treated With Guided Growth to Correct Idiopathic Genu Valgum

BACKGROUND

Guided growth is commonly used to treat frontal plane alignment deformities in skeletally immature individuals. Treatment aims are to correct the biomechanical loading of the knee and to avoid more invasive surgery that would be required after skeletal maturity. There is little published evidence of pain perception or functional limitations in this population. In addition, the intervention has the potential to worsen pain and function with hardware implantation, and symptoms may not fully resolve after removal. Understanding of pain and function limitations in this population is important to guide the clinical expectations.

METHODS

Individuals with idiopathic knee genu valgum who underwent hemiepiphysiodesis with tension plate constructs were identified through a medical records database search. Patient-reported outcomes measurement information system Physical Function/Mobility and Pain Interference domain scores were assessed before hemiepiphysiodesis, immediately before hardware removal, and after hardware removal. Radiographs were also assessed at these times to record the zones and angles of deformity and correction.

RESULTS

Twenty-eight subjects (53 operative limbs) contributed to the analysis. Mobility and pain interference as measured by the patient-reported outcomes measurement information system were below typical values in a small percentage of the population studied, only 3.6% scored in the moderate and none in the severe categories for both domains. Valgus by radiographic zone was corrected in all patients without significant rebound at follow-up. Compared with preoperative levels, mobility scores improved before hardware removal. Pain Interference scores improved both before hardware removal and at the final follow-up.

CONCLUSIONS

Frontal plane knee deformities in the idiopathic population do not cause pain or limit mobility in most subjects. This is critical information, emphasizing that surgical decisions may be made based on the deformity alone, presence of symptoms, and possible future morbidity secondary to valgus deformity. If surgery is postponed because an individual is asymptomatic, the window for correction with guided growth may be lost. Individuals undergoing hemiepiphysiodesis can expect that their pain and function will not be worse during the time that hardware is in place and that surgery is likely to improve any pain they may be experiencing.

First-Time Lumbar Medial Branch Radiofrequency Ablation: Patient-Reported Outcomes Measurement Information System as a Metric of Outcome

OBJECTIVE

To investigate the ability of Patient-Reported Outcomes Measurement Information System (PROMIS) to capture the therapeutic effect of first-time medial branch radiofrequency ablation (RFA).

DESIGN

Before-after trial.

SETTING

Single academic spine center.

PARTICIPANTS

Patients who underwent first-time medial branch RFA for lumbar facet joint pain identified by dual comparative medial branch block with ≥80% pain relief between January 1, 2015 and September 1, 2019 were identified using procedural billing codes. Charts were reviewed manually to confirm accuracy and strict adherence to the 80% pain relief threshold for each medial branch block. Thirty-nine patients met the criteria and were included in this study (N=39).

INTERVENTIONS

Medial branch RFA.

MAIN OUTCOME MEASURES

PROMIS score domains of Depression, Pain Interference, and Physical Function collected pre- and post RFA were compared. Pretreatment scores were within 6 weeks prior to the first medial branch block. Posttreatment scores were between 5 weeks and 6 months after RFA. Paired-sample t test analyses were used to calculate responsiveness to treatment, with significance assigned as P<.05 prior to acquiring data. Effect size was calculated using Cohen's d.

RESULTS

PROMIS domains of Pain Interference and Physical Function demonstrated a statistically significant improvement (P=.004 and P=.017, respectively). The PROMIS domain of Depression did not demonstrate a statistically significant change (P=.12). The effect size was medium (d=-0.43) for Pain Interference, small/medium (d=0.31) for Physical Function, and small (d=-0.12) for Depression.

CONCLUSIONS

Medial branch RFA as a treatment for lumbar facet syndrome is associated with a statistical improvement in PROMIS domains of Physical Function and Pain Interference.

Convergent and Discriminative Validity of the PROMIS Physical Function 4 Questionnaire for Assessing Pain-related Disability in Low Back Pain Patients Seeking Chiropractic Care

STUDY DESIGN

A prospective cohort study.

OBJECTIVE

To investigate construct validity by examining the convergent and discriminative validity of the Patient-Reported Outcomes Measurement Information System Physical Function 4a (PROMIS-PF4) questionnaire in low back pain (LBP) patients seeking care from Danish chiropractors.

SUMMARY OF BACKGROUND DATA

The Roland-Morris Disability Questionnaire (RMDQ) is often used to assess physical functioning in LBP. However, it consists of 24 items, which is time consuming to complete in clinical practice. The PROMIS-PF4 questionnaire has only four items and may be more applicable for clinical use.

MATERIALS AND METHODS

Patients with LBP seeking care from chiropractors in Denmark completed the PROMIS-PF4, RMDQ, Subgroups for Targeted Treatment (STarT) Back screening tool, and Numeric Pain Rating Scale (NPRS) in advance of their first appointment with the chiropractor. Convergent validity was assessed using Spearman correlation coefficients between the PROMIS-PF4 and RMDQ and NPRS, respectively. Discriminative validity of the PROMIS-PF4 was assessed by calculating the area under the receiver operating characteristic curve (AUC) when plotting the PROMIS-PF4 t score against a reference case for RMDQ; NPRS; and high and low risk groups using the STarT Back screening tool.

RESULTS

Among 356 patients the PROMIS-PF4 questionnaire had strong convergent validity with the RMDQ ( r =-0.76) and moderate convergent validity with the NPRS ( r =-0.42). The PROMIS-PF4 had good and acceptable discriminative validity for disability (AUC=0.88) and high risk of persisting disability (AUC=0.72), and poor or no discriminative validity for pain intensity (AUC=0.66) and low-risk of persisting disability (AUC=0.26), respectively.

CONCLUSION

As hypothesized, for convergent validity the PROMIS-PF4 has stronger correlation with the RMDQ than the NPRS and good discriminative validity for identifying patients with pain-related disability and at high risk of persisting disability but not for identifying pain intensity or low-risk of persisting disability. Consequently, the PROMIS-PF4 has adequate construct validity for measuring pain-related disability in an LBP population in chiropractic care.

Childhood Adversity among Adults with Chronic Pain: Prevalence and Association with Pain-Related Outcomes

OBJECTIVES

Adverse childhood experiences (ACEs) have been linked to the development and impact of chronic pain in adulthood. The goal of this study was to investigate the prevalence of ACEs in a treatment-seeking sample of adults with chronic pain and the relationship between number and type(s) of ACEs and pain-related outcomes.

METHODS

Adults (N=1794) presenting for treatment at a multidisciplinary pain management center completed self-report measures of childhood adversity, pain, functioning, emotional distress, and adjustment to pain.

RESULTS

Participants endorsing ≥4 ACEs had significantly worse pain-related outcomes and lower quality of life compared to individuals reporting fewer ACEs. Having ≥3 ACEs was associated with higher anxiety and depression levels. Experiences of childhood neglect negatively affected mental health-related outcomes independent of number of ACEs. Significant sex differences were found in the number and type of ACEs reported, but not in the relationship between ACEs and outcome variables.

CONCLUSION

Findings suggest that the number and type of self-reported ACE(s) are associated with pain-related variables and psychosocial functioning in adults with chronic pain. Results highlight the importance of assessment of ACEs and trauma-informed care with patients with chronic pain.

The Impairment and Functioning Inventory Revised-English version: A validation study in individuals with disabilities and bothersome pain

BACKGROUND

Despite the relevance of daily function in individuals with chronic pain, few questionnaires have been designed to assess this domain in individuals with musculoskeletal pain. In addition, the Impairment and Functioning Inventory-Revised (IFI-R) is the only instrument that assesses perceived decreases in levels of daily activity after the onset of pain.

OBJECTIVE

To evaluate the psychometric properties of the English version of the IFI-R.

DESIGN

Cross-sectional study.

SETTING

A database of individuals with medical conditions commonly associated with chronic pain maintained by the University of Washington.

PATIENTS

A total of 470 individuals with chronic pain.

METHODS

Factorial validity was analyzed by conducting a confirmatory factor analysis via structural equation modeling. Internal consistency was evaluated by calculating Cronbach's α coefficients. Convergent validity was assessed by calculating Pearson correlation coefficients between the two scales of the IFI-R and the Patient Reported Outcome Measurement Information System (PROMIS) Pain Interference Scale. Criterion validity was analyzed by regression analysis via structural equation modeling.

MAIN OUTCOME MEASURES

The English version of the IFI-R (IFI-R-EV) for individuals with chronic pain.

RESULTS

The IFI-R-EV consists of 30 items with two related subscales: The Daily Function subscale (α = .86). and the Impairment subscale (α = .89). A significant correlation was found between these subscales and a measure of pain interference (r's = - .33, and .35 respectively; p's < .01). We also found statistically significant associations (p < .05) between daily function and depression (β = -.14) and pain intensity (β = -.13), between impairment and depression (β = .14) and pain intensity (β = .16), and between daily function and pain acceptance (β = .14).

CONCLUSIONS

The findings indicate that the IFI-R-EV provides valid and reliable measures of daily function and impairment in English-speaking individuals with a disability and chronic pain. These results are consistent with those obtained with the Spanish version.

What Does Your PROMIS Score Mean? Improving the Utility of Patient-Reported Outcomes at the Point of Care

STUDY DESIGN

Prospective cohort.

OBJECTIVES

Patient-Reported Outcome Measurement Information System (PROMIS) has been validated for lumbar spine. Use of patient-reported outcome (PRO) measures can improve clinical decision making and health literacy at the point of care. Use of PROMIS, however, has been limited in part because clinicians and patients lack plain language understanding of the meaning of scores and it remains unclear how best to use them at the point of care. The purpose was to develop plain language descriptions to apply to PROMIS Physical Function (PF) and Pain Interference (PI) scores and to assess patient understanding and preferences in presentation of their individualized PRO information.

METHODS

Retrospective analysis of prospectively collected PROMIS PF v1.2 and PI v1.1 for patients presenting to a tertiary spine center for back/lower extremity complaints was performed. Patients with missing scores, standard error >0.32, and assessments with <4 or >12 questions were excluded. Scores were categorized into score groups, specifically PROMIS PF groups were: <18, 20 ± 2, 25 ± 2, 30 ± 2, 35 ± 2, 40 ± 2, 45 ± 2, 50 ± 2, 55 ± 2, 60 ± 2, and >62; and PROMIS PI groups were: <48, 50 ± 2, 55 ± 2, 60 ± 2, 65 ± 2, 70 ± 2, 75 ± 2, 80 ± 2, and >82. Representative questions and answers from the PROMIS PI and PROMIS PF were selected for each score group, where questions with <25 assessments or representing <15% of assessments were excluded. Two fellowship-trained spine surgeons further trimmed the questions to create a streamlined clinical tool using a consensus process. Plain language descriptions for PROMIS PF were then used in a prospective assessment of 100 consecutive patients. Patient preference for consuming the score data was recorded and analyzed.

RESULTS

In total, 12 712 assessments/5524 unique patients were included for PF and 14 823 assessments/6582 unique patients for PI. More than 90% of assessments were completed in 4 questions. The number of assessments and patients per scoring group were normally distributed. The mean PF score was 37.2 ± 8.2 and the mean PI was 63.3 ± 7.4. Plain language descriptions and compact clinical tool was were generated. Prospectively 100 consecutive patients were surveyed for their preference in receiving their T-score versus plain language description versus graphical presentation. A total of 78% of patients found receiving personalized PRO data helpful, while only 1% found this specifically not helpful. Overall, 80% of patients found either graphical or plain language more helpful than T-score alone, and half of these preferred plain language and graphical descriptions together. In total, 89% of patients found the plain language descriptions to be accurate.

CONCLUSIONS

Patients at the point of care are interested in receiving the results of their PRO measures. Plain language descriptions of PROMIS scores enhance patient understanding of PROMIS numerical scores. Patients preferred plain language and/or graphical representation rather than a numerical score alone. While PROs are commonly used for assessing outcomes in research, use at point of care is a growing interest and this study clarifies how they might be utilized in physician-patient communication.

More than Hurt Feelings: The Wear and Tear of Day-to-Day Discrimination in Adults with Chronic Pain

OBJECTIVE

To examine the extent to which self-reported experiences of discrimination are associated with pain interference among men and women with chronic non-cancer pain.

METHODS

Data are from the Study of Midlife in the United States (MIDUS) Refresher Cohort. The analytic sample consisted of 207 adults with chronic pain (54.2 ± 12.8 years; 53.6% female) who completed the Major Experiences of Discrimination and Everyday Discrimination scales. Regression analyses examined cross-sectional relations between discrimination and pain interference.

RESULTS

On average, the level of pain interference was moderate in the sample (mean = 3.46, standard deviation = 2.66; observed range 0-10). Approximately a third of respondents reported at least one major discriminatory event in their lifetime, while 22% reported three or more discriminatory lifetime events. Everyday discrimination scores averaged 14.19 ± 5.46 (observed range 0-33). With adjustment for sociodemographics, physical health, cognitive and psychological factors, social isolation, and loneliness, everyday discrimination was associated with increased pain interference (B = 0.099; 95% confidence interval [CI]: 0.02 to 0.17).

CONCLUSION

These findings add weight to the importance of day-to-day experiences of interpersonal discrimination by documenting independent associations with functional interference in adults with chronic pain.

Preoperative characteristics predictive of PROMIS Pain Interference two years after shoulder surgery

Introduction

The objective of this study was to identify preoperative characteristics associated with worse Patient-Reported Outcomes Measurement Information System (PROMIS) Pain Interference (PI) two years after shoulder surgery.

Methods

This was a retrospective analysis of prospectively collected data on 293 patients who underwent elective shoulder surgery. Survey questionnaires were collected within one week of surgery and then two years postoperatively. Bivariate analysis was used to identify associations and multivariable analysis was used to control for confounding variables.

Results

Worse two-year PROMIS PI was significantly correlated with older age, higher BMI, greater comorbidities, more prior surgeries, and multiple socio-demographic factors. Less improvement in PROMIS PI was significantly correlated with greater comorbidities, more previous surgeries, unemployment, prior orthopaedic surgery on the operative joint, and a higher American Society of Anesthesiologists (ASA) score. Better scores on all preoperative patient-reported outcome measures correlated with better two-year PROMIS PI. Multivariable analysis demonstrated that worse two-year PROMIS PI was independently predicted by the following preoperative factors: Workers' Compensation claim, opioid use, worse whole body Numeric Pain Score, and worse PROMIS PI. Less improvement in two-year PROMIS PI was predicted by the same preoperative factors.

Conclusion

Worse PROMIS PI after shoulder surgery was associated with older age, greater comorbidities, mental health impairment, and lower socioeconomic status. Preoperative predictors of worse pain interference two years after shoulder surgery included Workers' Compensation, opioid use, worse whole body pain, and worse PROMIS PI.

What patient factors and Patient-Reported Outcomes Measurement Information System domains are associated with worse pain coping in pediatric orthopaedic patients in the United States?

We sought to better understand the relationship between Patient-Reported Outcomes Measurement Information System (PROMIS) mobility, pain interference (PI) and depressive symptoms scores, as well as determine what patient factors and PROMIS domains were associated with worse pain coping (PROMIS PI), in a pediatric orthopaedic population. Between 27 August 2015 and 30 April 2019, new pediatric orthopaedic patients 18 years or younger (or their guardians as a proxy) were asked to complete PROMIS mobility, PI and depressive symptoms domains at an academic medical center pediatric orthopaedic clinic. Pearson correlation coefficients (r) were calculated between each PROMIS domain. Linear multivariate regression analysis was used to determine patient characteristics and PROMIS domains associated with presenting PROMIS PI scores. There was a strong-moderate correlation between PROMIS mobility and PI (r = -0.66, P < 0.001), while the correlation between PROMIS mobility and depressive symptoms was moderate-poor (r = -0.38, P < 0.001). There was a moderate correlation between PROMIS depressive symptoms and PI (r = 0.54, P < 0.001). In multivariate linear regression analysis, female gender (β = 0.82, P < 0.001), self-reported black race (β = 0.94, P < 0.001), Medicaid insurance (β = 0.82, P < 0.001) and worsening depressive symptoms (β = 0.33, P < 0.001) were associated with worse pain coping mechanisms, while increasing mobility (β = -0.47, P < 0.001) was associated with better pain coping mechanisms. Poor mobility and worse depressive symptoms are associated with worse pain coping mechanisms. Additionally, Medicaid insurance status, black race and female gender are also associated with worse physical limitations secondary to pain.

Establishing Age-calibrated Normative PROMIS Scores for Hand and Upper Extremity Clinic

The purpose of our study is to investigate differences in normative PROMIS upper extremity function (PROMIS-UE), physical function (PROMIS-PF), and pain interference (PROMIS-PI) scores across age cohorts in individuals without upper extremity disability.

STarT-Lower Extremity Screening Tool at Six-weeks Predicts Pain and Physical Function 12-months after Traumatic Lower Extremity Fracture

BACKGROUND

Patients with lower extremity fracture requiring surgical fixation often have poor long-term pain and disability outcomes. This indicates the need for a risk stratification tool that can inform patient prognosis early in recovery. The purpose of this study was to determine the predictive validity of the STarT-Lower Extremity Screening Tool (STarT-LE) in patients with lower extremity fracture requiring surgical fixation.

MATERIALS AND METHODS

One-hundred and twenty-two patients (41.7 ± 14.7 years, 54% male) with lower extremity fracture and no history of chronic pain were enrolled in this prospective cohort study. Patients completed the STarT-LE Screening Tool six-weeks after definitive fixation. Validated measures of chronic pain development, pain interference, and physical function were collected at 12-months. STarT-LE low, medium, and high risk subgroups were compared against each outcome measure with chi-square, one-way analysis of variance, and sensitivity and specificity analyses. Multivariable linear regression analyses determined if STarT-LE risk subgroups at six weeks were associated with each outcome at 12 months when controlling for important baseline demographics.

RESULTS

Twelve-month follow-up was completed by 114 patients (93.4%). Increase in STarT-LE risk subgroup at six-weeks was associated with higher frequency of chronic pain (Low: 14.7%, Medium: 48.3%, High: 85.0%), worse pain interference (Low: 48.6 ± 8.88, Medium: 56.33 ± 8.79, High: 61.65 ± 7.74), and worse physical function (Low: 50.77 ± 9.89, Medium: 42.52 ± 6.47, High: 37.44 ± 7.46) at 12-months. The low risk subgroup had high sensitivity (range: 84.9%-93.9%) and the high risk subgroup had high specificity (range: 87.7%-95.2%) for dichotomized 12-month outcomes. The multivariable results showed that medium and high STarT-LE risk categories were associated with chronic pain development (Medium odds ratio: 3.90, 95%CI: 1.11 to 13.66; High odds ratio: 13.14, 95%CI: 2.25 to 76.86), worse pain interference (Medium: β:4.37, 95%CI: 0.17 to 8.58; High: β:7.01, 95%CI: 1.21 to 12.81), and worse physical function (Medium: β:-3.76, 95%CI: -7.41 to -0.11; β:-7.44, 95%CI:-12.47 to -2.41), respectively, when controlling for important baseline variables.

CONCLUSION

The STarT-LE has the potential to identify patients at-risk for poor pain and functional outcomes, and may help inform the post-surgical management of patients with traumatic LE injury.

"Living Well with Chronic Pain": Integrative Pain Management via Shared Medical Appointments

Objective

To evaluate the effectiveness of a multidisciplinary, nonpharmacological, integrative approach that uses shared medical appointments to improve health-related quality of life and reduce opioid medication use in patients with chronic pain.

Design

This is a retrospective, pre–post review of “Living Well with Chronic Pain” shared medical appointments (August 2016 through May 2018).

Setting

The appointments included eight 3-hour-long visits held once per week at an outpatient wellness facility.

Subjects

Patients with chronic, non–cancer-related pain.

Methods

Patients received evaluation and evidence-based therapies from a team of integrative and lifestyle medicine professionals, as well as education about nonpharmacological therapeutic approaches, the etiology of pain, and the relationship of pain to lifestyle factors. Experiential elements focused on the relaxation techniques of meditation, yoga, breathing, and hypnotherapy, while patients also received acupuncture, acupressure, massage, cognitive behavioral therapy, and chiropractic education. Patients self-reported data via the Patient-Reported Outcomes Measurement Information System (PROMIS-57) standardized questionnaire. Use of opioid medications was evaluated in morphine milligram equivalents.

Results

A total of 178 participants completed the PROMIS-57 questionnaire at the first and the last visits. Statistically significant improvements in all domains (Physical Functioning, Anxiety, Depression, Fatigue, Social Roles, Pain Interference, and Sleep Disturbance) were observed (P < 0.001) between the pre-intervention (visit 1) and post-intervention (visit 8) scores. Average opioid use decreased nonsignificantly over the 8-week intervention, but the lower rate of opioid use was not sustained at 6 and 12 months’ follow-up.

Conclusions

Patients suffering from chronic pain who participated in a multidisciplinary, nonpharmacological treatment approach delivered via shared medical appointments experienced reduced pain and improved measures of physical, mental, and social health without increased use of opioid pain medications.

Evaluation of transforaminal epidural steroid injections for discogenic axial lumbosacral back pain utilizing PROMIS as an outcome measure

BACKGROUND CONTEXT

Discogenic lumbosacral back pain continues to present a challenging clinical entity with limited, controversial therapeutic options. No study to date has evaluated the efficacy of fluoroscopically guided transforaminal epidural steroid injections (TFESI) in a homogenous patient population with axial lumbosacral back pain from discogenic pathology utilizing strict, explicitly clinical and radiographic criteria. Additionally, there is a paucity of published data utilizing Patient Reported Outcome Measurement Information System (PROMIS) scores as an outcome measure for interventional spine procedures.

PURPOSE

Evaluate the therapeutic effect of TFESIs in a specific subset of patients with discogenic axial lumbosacral back pain. Investigate PROMIS as an outcome measure for interventional spine procedures targeting focal degenerative spinal pathology.

STUDY DESIGN/SETTING

Retrospective review of patients presenting to a multidisciplinary, tertiary academic spine center.

PATIENT SAMPLE

Three thousand eight hundred eighty-one patients were screened for inclusion. A total of 26 patients with discogenic axial low back, based on strict clinical and radiographic criteria, underwent TFESIs. All patients had axial low back pain without radicular pain, ≥3 clinical features of discogenic pain, corroborative radiographic features of active discogenic pathology on lumbar spine magnetic resonance imaging without confounding spinal pathology.

OUTCOME MEASURES

PROMIS Pain Interference (PI) v1.1, PROMIS Physical Function (PF) v1.2/v2.0, and PROMIS Depression (D) v1.0 outcome scores were collected at baseline and postprocedure follow-up.

METHODS

Query of an institutional, patient reported outcome database and subsequent retrospective review of electronic medical records was performed. Statistical analysis comparing baseline and postprocedural PROMIS outcome scores and correlation between these instruments was performed. Additionally, an exploratory investigation of minimal clinically important difference achievement rates was performed.

RESULTS

Analysis determined a statistically significant improvement in PROMIS PI (p=.017, 95% CI=-8.02 to -1.82) and PROMIS PF (p=.003, 95% CI=0.91-8.72) scores after treatment with TFESIs. At post treatment time points, TFESI had medium effect size on pain (d=0.55) and function (d=0.59). Change in PROMIS D scores (p=.488, 95% CI -1.74-3.54; d=.08) did not demonstrate statistical significance. Pearson correlation demonstrated a moderate negative correlation (r=-0.544, p=.004) between PROMIS PF with PROMIS PI. Correlation between PROMIS PF (r=-0.239, p=.24) and PROMIS PI (r=0.198, p=.33) with PROMIS D was not significant. Fourteen (53.8%) and 9 (34.6%) subjects achieved minimum clinically important difference (MCID) for PROMIS PI and PROMIS PF, respectively. Nine subjects (34.6%) achieved MCID for PROMIS D despite not otherwise reaching statistical significance otherwise.

CONCLUSIONS

Utilizing PROMIS as an outcome measure, discogenic axial lumbosacral back pain patients appear to benefit from TFESI in terms of pain and physical function. This study contributes to the growing body of literature utilizing PROMIS scores in patients with clinical sequelae of degenerative spinal pathology; however, prospective studies are needed.

Patient-Reported Outcomes Measurement Information System Physical Function Has a Lower Effect Size and is Less Responsive Than Legacy Hip Specific Patient Reported Outcome Measures Following Arthroscopic Hip Surgery

PURPOSE

To compare the use and responsiveness of Patient Reported Outcomes Measurement Information System (PROMIS) to legacy patient-reported outcome measures (PROMs) in patients undergoing hip arthroscopy for femoroacetabular impingement syndrome (FAIS) at 6-month follow-up.

METHODS

Data from patients who underwent primary hip arthroscopy with routine capsular closure between August 2018 and January 2019 for the treatment of FAIS were analyzed. Preoperative outcomes, 6-month postoperative outcomes, and demographics were recorded. Primary outcome measures included PROMIS Physical Function (PROMIS-PF), PROMIS Pain Interference (PROMIS-PI), and PROMIS Depression. The legacy PROMs included Hip Outcome Score Activities of Daily Living (HOS-ADL), Hip Outcome Score Sport Subscale (HOS-SS), and the international hip outcome tool 12 questions (iHOT-12). Floor and ceiling effects along with the responsiveness and Cohen's d effect size of each PROM tool were calculated.

RESULTS

Ninety-six patients with an average age and body mass index of 32.4 ± 11.9 years and 25.9 ± 6.1 kg/m², respectively, were included in the final analysis. All outcomes were significantly higher at 6 months compared with the preoperative level (P < .001) except for PROMIS Depression (P = .873). PROMIS-PF demonstrated excellent correlation with HOS-SS (r = 0.81; P < .001), very good correlation with HOS-ADL (r = 0.73; P < .001), and good correlation with iHOT-12 (r = 0.68; P < .001). No floor was observed for any measure. The effect size was large for all outcomes, except PROMIS Depression (d = 0.04), but largest for iHOT12 (d = 1.87) followed by HOS-ADL (d = 1.29). The iHOT-12 was more responsive than PROMIS-PI (relative efficiency [RE] = 3.95), PROMIS-PF (RE = 4.13), HOS-ADL (RE = 2.26), and HOS-SS (RE = 3.84). HOS-SS was similarly responsive to PROMIS-PI (RE=1.03) and PROMIS-PF (RE=1.08). However, PROMIS-PF was overall the least responsive.

CONCLUSIONS

In patients at 6 months postoperatively from hip arthroscopy for FAIS, iHOT-12 was the most responsive and had the largest effect size. In contrast, PROMIS-PF had a lower effect size compared with legacy hip-specific PROMs. Additionally, PROMIS-PF did not correlate as well with iHOT-12 compared with HOS-SS.

Performance of PROMIS Physical Function, Pain Interference, and Depression Computer Adaptive Tests Instruments in Patients Undergoing Meniscal Surgery

Purpose

To compare the performance of the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF), pain interference (PIF), and depression computer adaptive tests (CAT) relative to legacy instruments in patients undergoing meniscal surgery.

Methods

Patients scheduled to undergo meniscal surgery completed legacy knee function PROMs (International Knee Documentation Committee [IKDC], Knee Injury and Osteoarthritis Outcome Score [KOOS] subscores), Marx Activity Rating Scale (MARS), Veterans-Rand 12 (VR12), Short Form 12 (SF12), and the Brief Resilience Scale (BRS) alongside PROMIS PF, PIF, and Depression preoperatively. Spearman rank correlations were calculated, and score distributions were examined for floor and ceiling effects.

Results

152 patients (46.6 ± 14.9 years, 67.1% male) completed PROMs for appropriate inclusion. PROMIS PF yielded high-moderate to high correlations with the IKDC and KOOS subscales (r = 0.61 to 0.73), demonstrating similar performance to the IKDC. PROMIS PIF demonstrated moderately high-moderate to high correlations with the IKDC, KOOS subscales, VR-12 Physical Component Score (PCS), and SF12 PCS (r = 0.62 to 0.71), performing comparably to KOOS Pain (r = 0.55 to 0.92). PROMIS Depression demonstrated moderate to high-moderate correlations with the mental health legacies (r = 0.46 to 0.66). Significant ceiling effects were observed for MARS (n = 29, 18.8%), and significant floor effects were exhibited by PROMIS Depression (n = 38, 25%) and MARS (n = 27, 17.6%).

Conclusion

The PROMIS PF, PIF CAT, and Depression instruments exhibit comparable performance profiles relative to legacy knee PROMs. PROMIS PF and PIF demonstrated no floor and ceiling effects, whereas PROMIS Depression exhibited a significant relative floor effect. PROMIS PF and PIF may be appropriately used to establish functional baselines preoperatively.

Validation of Pediatric Self-Report Patient-Reported Outcomes Measurement Information System (PROMIS) Measures in Different Stages of Legg-Calvé-Perthes Disease

OBJECTIVES

Patient-reported outcomes (PRO) assessing health-related quality of life (HRQoL) are important outcome measures, especially in Legg-Calvé-Perthes disease (LCPD) where symptoms (pain and limping), activity restrictions, and treatments vary depending on the stage of the disease. The purpose of this study was to investigate the validity of the Patient-reported Outcomes Measurement Information System (PROMIS) for measuring HRQoL of patients with LCPD in various stages of the disease.

METHODS

This is a multicenter validity study. Patients with LCPD between 4 and 18 years old were included and classified into modified Waldenström stages of disease: Early (1 or 2A), Late (2B or 3), or Healed (4). Seven PROMIS domains were collected, including Pain Interference, Fatigue, Mobility, Depression, Anger, Anxiety, and Peer Relationships. Convergent, discriminant, and known group validity was determined.

RESULTS

A total of 190 patients were included (mean age: 10.4±3.1 y). All 7 domains showed the worst scores in patients in the Early stage (known group validity). Within each domain, all domains positively correlated to each other (convergent validity). Patients who reported more anxiety, depression, and anger were associated with decreased mobility and increased fatigue and pain. Peer relationships had no to weak associations with other domains (discriminant validity).

CONCLUSIONS

PROMIS has construct validity in measuring the HRQoL of patients in different stages of LCPD, suggesting that PROMIS has potential to serve as a patient-reported outcome tool for this population.

Establishing "Normal" Patient-Reported Outcomes Measurement Information System Physical Function and Pain Interference Scores: A True Reference Score According to Adults Free of Joint Pain and Disability

Numerous recent studies have demonstrated the validity and efficiency of the National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) forms in patients undergoing orthopaedic surgical procedures. It is assumed that a score of 50 in each domain represents the health state of a “reference” population, but this threshold has not been definitively proven. In order to truly assess whether a given orthopaedic intervention is successful, the comparative scores of healthy individuals must be known for any given health domain measured. Therefore, the purpose of this study was to determine baseline scores for the PROMIS general physical function (PROMIS-PF), pain interference (PROMIS-PI), and upper-extremity physical function (PROMIS-UE) domains in physically healthy, asymptomatic adult individuals. We hypothesized that, in individuals <40 years old, the mean PROMIS-PF and PROMIS-UE scores would be >50 and PROMIS-PI scores would be <50. We further hypothesized that these scores would be impacted by participant age.

Creating value in spine surgery: using patient reported outcomes to compare the short-term impact of different orthopedic surgical procedures

BACKGROUND CONTEXT

Society increasingly asks Medicine to create "value" for patients. As health-care costs rise, this question will become more important. Debate exists regarding the relative "value" of many surgical procedures, including spinal surgery. Comparison of the relative value that patients experience after different orthopedic procedures is theoretical, but informs the ongoing debate.

METHODS

The Patient Reported Outcome Measurement Information System (PROMIS) assessments for Physical Function, Pain Interference, and Depression are routinely collected in our orthopedic clinics. Patients who underwent lumbar discectomy (DSC) or arthroscopic anterior cruciate ligament reconstruction (ACLR) were retrospectively identified. Data relating to PROMIS domains, patient demographics, and other relevant encounter details were extracted. The primary outcomes were (1) preoperative PROMIS domain scores, (2) scores at a minimum of 40 days postoperatively for DSC patients and 133 days postoperatively for ACLR patients, and (3) the change in scores with surgery. Propensity score matching identified age-, sex-, race-, and comorbidity-matched groups from each cohort. Chi-square tests and nonparametric Kruskal-Wallis tests compared the distribution of outcomes and characteristics. Multivariate linear regression models with interactions between the matched cohort and operative phase estimated the change in the outcomes scores between the two cohorts and controlled for the baseline differences between them.

RESULTS

Before surgery, the DSC cohort had lower physical function, higher pain interference and higher depression scores as compared with the ACLR cohort. This pattern remained postoperatively, indicating less desirable outcomes for DSC patients. However, after controlling for their baseline scores, DSC patients experienced significantly greater improvements after surgery of 3.84 (95% CI 1.08-6.60; p=.01), -4.87 (95% CI -7.52 to -2.23; p<.001), and -2.95 (95% CI -5.70 to -0.21; p=.04) points in their physical function, pain interference, and depression scores, respectively, as compared with ACLR patients.

CONCLUSIONS

Based upon PROMIS assessments at short-term follow-up, DSC patients receive a larger benefit from surgery than ACLR despite the overall less desirable postoperative PROMIS scores in the DSC cohort. This result, while theoretical, informs the debate regarding the comparative value of DSC to patients.

A Comparison of PROMIS UE Versus PF: Correlation to PROMIS PI and Depression, Ceiling and Floor Effects, and Time to Completion

PURPOSE

This study aimed to (1) determine the correlation of Patient-Reported Outcomes Measurement Information System (PROMIS) Physical Function (PF) with PROMIS Upper Extremity (UE) and compare the correlations of PF and UE with PROMIS Pain Interference (PI) and PROMIS Depression; (2) compare the ability of PF and UE to capture health outcomes across the spectrum in patients seeking hand care; and (3) compare the time to completion for PROMIS PF to that for PROMIS UE.

METHODS

Patients presenting to a hand clinic between October, 2015 and October, 2017 were asked to complete PROMIS PF, UE, PI, and Depression computerized adaptive tests. Spearman correlation coefficients (ρ) were calculated between the domains. Ceiling and floor effects and time to completion of each domain were compared.

RESULTS

A total of 20,489 unique visits representing 10,344 patients met inclusion criteria. On average, PROMIS UE demonstrated more functional disability than did PROMIS PF (PF: 43.9 [95% confidence interval (CI), 43.7-44.0] vs UE: 38.5 [95% CI, 38.4-38.7]). PROMIS PF and UE were positively correlated (ρ = 0.79) and both were inversely correlated with PROMIS PI (PF: ρ = -0.72; UE: ρ = -0.72). PROMIS PF and UE were both inversely correlated with PROMIS Depression (PF: ρ = -0.44; UE: ρ = -0.44). PROMIS PF demonstrated better ceiling (0.6% vs 7.5%) and floor effects (0.07% vs 0.4%). The PROMIS UE CAT was completed in about the same time as the PROMIS PF CAT (UE: 59.8 seconds [95% CI, 59.3-60.3 seconds] vs PF: 54.1 seconds [95% CI, 53.8-54.5 seconds]).

CONCLUSIONS

PROMIS PF captures functional outcomes similar to those of the UE domain with better performance (ie, ceiling and floor effects) in patients with hand pathologies.

CLINICAL RELEVANCE

Hand surgeons should consider the trade-off of using PROMIS PF instead of PROMIS UE or vice versa when selecting a domain for patient care. Although PROMIS PF may capture slight variations in function at the extremes better than the current PROMIS UE, this may not be as clinically important as capturing large changes in upper-extremity function more specifically, which PROMIS UE accomplishes.

Patient-Reported Outcomes Measurement Information System physical function and pain interference in spine surgery

OBJECTIVE

The Patient-Reported Outcomes Measurement Information System (PROMIS) is an adaptive, self-reported outcomes assessment tool that utilizes item response theory and computer adaptive testing to efficiently and precisely evaluate symptoms and perceived health status. Efforts to implement and report PROMIS outcomes in spine clinical practice remain limited. The objective of this retrospective cohort study is to evaluate the performance and psychometric properties of PROMIS physical function (PF) and pain interference (PI) among patients undergoing spine surgery.

METHODS

The authors identified all patients who underwent spine surgery at their institution between 2016 and 2018, and for whom there was retrievable PROMIS data. Descriptive statistics were calculated to summarize demographics, operative characteristics, and patient-reported outcomes. Assessments were evaluated preoperatively, and postoperatively within 2 months (early), 6 months (intermediate), and up to 2 years (late). Pairwise change scores were calculated to evaluate within-subjects differences and construct responsiveness over time. Pearson's correlation coefficients were used to evaluate the association between PROMIS PF and PI domains. Subgroup analysis was performed based on the primary diagnoses of cervical radiculopathy, cervical myelopathy, or lumbar degenerative disease.

RESULTS

A total of 2770 patients (1395 males, 50.4%) were included in the analysis. The mean age at the time of surgery was 57.3 ± 14.4 years. Mean postoperative follow-up duration was 7.6 ± 6.2 months. Preoperatively, patients scored an average 15.1 ± 7.4 points below the normative population (mean 50 ± 10 points) in PF, and 15.8 ± 6.8 points above the mean in PI. PROMIS PF required a mean of 4.1 ± 0.6 questions and median 40 seconds (interquartile range [IQR] 29-58 seconds) to be completed, which was similar to PI (median 4.3 ± 1.1 questions and 38 seconds [IQR 27-59 seconds]). Patients experienced clinically meaningful improvements in PF and PI, which were sustained throughout the postoperative course. PROMIS instruments were able to capture anticipated changes in PF and PI, although to a lesser degree in PF early postoperatively. There was a strong negative correlation between PROMIS PF and PI scores at baseline (Pearson's r = -0.72) and during follow-up appointments (early, intermediate, and late |r| > 0.6, each). Subgroup analysis demonstrated similar results within diagnostic groups compared to the overall cohort. However, the burden of PF limitations and PI was greater within the lumbar spine disease subgroup, compared to patients with cervical radiculopathy and myelopathy.

CONCLUSIONS

Patients receiving care at a tertiary spine surgery outpatient clinic experience significant overall disability and PI, as measured by PROMIS PF and PI computer adaptive tests. PROMIS PF and PI health domains are strongly correlated, responsive to changes over time, and facilitate time-efficient evaluations of perceived health status outcomes in patients undergoing spine surgery.

PROMIS Pain Interference Is Superior to the Likert Pain Scale for Pain Assessment in Spine Patients

STUDY DESIGN

Cross-sectional cohort analysis.

OBJECTIVE

(1) To assess the correlation between Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) and pain interference (PI) in patients seeking spine care; (2) to assess the correlation between PROMIS PF and the Likert Pain Scale (LPS) in patients seeking spine care; (3) to determine which pain scale best correlates to physical function overall and by number of clinic visits.

SUMMARY OF BACKGROUND DATA

An accurate understanding of a patient's pain level is beneficial in setting clinical and pain management expectations. There is limited work analyzing which instrument best captures pain and its impact on function in patients seeking spine care.

METHODS

Spine center patients from February 2015 to November 2017 were asked to complete PROMIS PF and PI domains, as well as to report their pain level on a 0 (no pain) to 10 (worst pain) LPS at each visit. Pearson correlation coefficients were calculated between PROMIS PF and PROMIS PI; PROMIS PI and LPS; and PROMIS PF and LPS. Fisher r-z transformation method was utilized for confidence intervals (CIs) and to determine significant correlation differences. Analyses were performed for all data, as well as by office visit. Significance was set at P < 0.01.

RESULTS

A total of 21,774 first visit, 11,130 second visit, 6575 third visit, 4202 fourth visit, and 2819 fifth visit patients' data were recorded. PROMIS PF demonstrated a moderate correlation with the LPS over all visits (r = 0.46-0.49, P < 0.01). PROMIS PF demonstrated a strong correlation with PROMIS PI over all visits (r = 0.73-0.77, P < 0.01). Overall, PROMIS PI demonstrated significantly better correlation to self-reported physical function than the LPS (P < 0.01).

CONCLUSION

While PROMIS PI and the LPS both demonstrated significant correlation with self-reported physical function, PROMIS PI had a significantly stronger correlation.

Correlation of PROMIS Physical Function, Pain Interference, and Depression in Pediatric and Adolescent Patients in the Ambulatory Sports Medicine Clinic

Background:

Recently, interest has increased in incorporating the National Institutes of Health Patient-Reported Outcomes Measurement Information System (PROMIS) outcomes into clinical and research applications in sports medicine. The PROMIS forms have not been studied in pediatric and adolescent sports medicine patients.

Purpose/Hypothesis:

The goal of this study was to determine the correlation between PROMIS Computer Adaptive Test (CAT) forms measuring physical function, pain interference, and depression in pediatric and adolescent patients seen in the ambulatory sports medicine clinic. We hypothesized that there would be a negative correlation between physical function and pain interference as well as depression, as has been demonstrated in adult patient populations.

Study Design:

Cross-sectional study; Level of evidence, 3.

Methods:

All patients aged 8 to 17 years seen by 3 shoulder and sports medicine providers were included in this study. Patients completed a series of PROMIS CAT forms at clinic visits, including the PROMIS-PF and PROMIS-UE (Physical Function and Upper Extremity; depending on the nature of the complaint), PROMIS-PI (Pain Interference), and PROMIS-Depression subscales. Pearson correlation coefficients were calculated between the PROMIS forms as well as with other patient demographic data.

Results:

A total of 236 patient visits (152 patients) were included in the study, comprising 712 total PROMIS CAT forms. A negative correlation was found between PROMIS-PF and both PROMIS-Depression (R = –0.34) and PROMIS-PI (R = –0.76). These correlations with PROMIS-Depression and PROMIS-PI were –0.21 and –0.75, respectively, when considering the PROMIS-UE CAT. Patient demographic information had minimal impact on PROMIS scores as well as on correlations between scores.

Conclusion:

Correlations between physical function, pain interference, and depression were found to be similar in pediatric patients as they are in adult patients, as measured by PROMIS CAT forms.

The Patient-Reported Outcomes Measurement Information System in spine surgery: a systematic review

OBJECTIVEThe Patient-Reported Outcomes Measurement Information System (PROMIS) was developed to provide a standardized measure of clinical outcomes that is valid and reliable across a variety of patient populations. PROMIS has exhibited strong correlations with many legacy patient-reported outcome (PRO) measures. However, it is unclear to what extent PROMIS has been used within the spine literature. In this context, the purpose of this systematic review was to provide a comprehensive overview of the PROMIS literature for spine-specific populations that can be used to inform clinicians and guide future work. Specifically, the authors aimed to 1) evaluate publication trends of PROMIS in the spine literature, 2) assess how studies have used PROMIS, and 3) determine the correlations of PROMIS domains with legacy PROs as reported for spine populations.METHODSStudies reporting PROMIS scores among spine populations were identified from PubMed/MEDLINE and a review of reference lists from obtained studies. Articles were excluded if they did not report original results, or if the study population was not evaluated or treated for spine-related complaints. Characteristics of each study and journal in which it was published were recorded. Correlation of PROMIS to legacy PROs was reported with 0.1 ≤ |r| < 0.3, 0.3 ≤ |r| < 0.5, and |r| ≥ 0.5 indicating weak, moderate, and strong correlations, respectively.RESULTSTwenty-one articles were included in this analysis. Twelve studies assessed the validity of PROMIS whereas 9 used PROMIS as an outcome measure. The first study discussing PROMIS in patients with spine disorders was published in 2012, whereas the majority were published in 2017. The most common PROMIS domain used was Pain Interference. Assessments of PROMIS validity were most frequently performed with the Neck Disability Index. PROMIS domains demonstrated moderate to strong correlations with the legacy PROs that were evaluated. Studies assessing the validity of PROMIS exhibited substantial variability in PROMIS domains and legacy PROs used for comparisons.CONCLUSIONSThere has been a recent increase in the use of PROMIS within the spine literature. However, only a minority of studies have incorporated PROMIS for its intended use as an outcomes measure. Overall, PROMIS has exhibited moderate to strong correlations with a majority of legacy PROs used in the spine literature. These results suggest that PROMIS can be effective in the assessment and tracking of PROs among spine populations.

PROMIS Pain Interference Is Superior vs Numeric Pain Rating Scale for Pain Assessment in Foot and Ankle Patients

BACKGROUND:

The Numeric Pain Rating Scale (NPRS) is a popular method to assess pain. Recently, the Patient-Reported Outcomes Measurement Information System (PROMIS) has been suggested to be more accurate in measuring pain. This study aimed to compare NPRS and PROMIS Pain Interference (PI) scores in a population of foot and ankle patients to determine which method demonstrated a stronger correlation with preoperative and postoperative function, as measured by PROMIS Physical Function (PF).

METHODS:

Prospective PROMIS PF and PI and NPRS data were obtained for 8 common elective foot and ankle surgical procedures. Data were collected preoperatively and postoperatively at a follow-up visit at least 6 months after surgery. Spearman correlation coefficients were calculated to determine the relationship among NPRS (0-10) and PROMIS domains (PI, PF) pre- and postoperatively. A total of 500 patients fit our inclusion criteria.

RESULTS:

PROMIS PF demonstrated a stronger correlation to PROMIS PI in both the pre- and postoperative settings (preoperative: ρ = -0.66; postoperative: ρ = -0.69) compared with the NPRS (preoperative: ρ = -0.32; postoperative:ρ = -0.33). Similar results were found when data were grouped by Current Procedural Terminology (CPT) code.

CONCLUSION:

PROMIS PI was a superior tool to gauge a patient's preoperative level of pain and functional ability. This information may assist surgeons and patients in setting postoperative functional expectations and pain management.

The Recovery Curve for the Patient-Reported Outcomes Measurement Information System Patient-Reported Physical Function and Pain Interference Computerized Adaptive Tests After Primary Total Knee Arthroplasty

BACKGROUND

We sought to characterize the typical recovery in physical function (PF) and pain interference (PI) after TKA using Patient-Reported Outcomes Measurement Information System (PROMIS) patient-reported outcome (PRO) measures.

METHODS

Ninety-one patients were enrolled into an institutional review board -approved prospective observational study. PROs were obtained preoperatively and postoperatively at 6 weeks, 3 months, 6 months, and 1 year. PROs included the PROMIS PF computerized adaptive test (CAT) and the PROMIS PI CAT. Generalized estimating equations were used to evaluate outcomes over time.

RESULTS

There was no difference in the preoperative and 6-week postoperative T-scores for the PF CAT (P = .410). However, all subsequent postoperative T-scores were greater than the preoperative T-score (all, P < 0.05). There was a significant reduction in PI CAT T-scores between the preoperative and all subsequent postoperative T-scores (all, P < .05). A clinically important difference in PF CAT T-scores (β = 5.44, 95% confidence interval 4.10-6.80; P < .001) and PI CAT T-scores (β = -7.46, 95% confidence interval -9.52 to -5.40; P < 0.001) was seen between the preoperative and 3-month postoperative visits. Sixty-three percent of the improvement in PF occurred by 3 months, and 89% had occurred by 6 months. The majority of reduction in PI (68%) occurred by 3 months and 90% had occurred by 6 months.

CONCLUSION

The greatest magnitude of improvement in both PF and PI occurred within the first 3 months. After 6 months, patients might expect modest improvements in PF and mild reductions of PI. Patients and surgeons should use this information for setting expectations, planning for recovery, and improving care.
