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.

Evaluating the Performance of an Automated Patient-Reported Outcomes Collection Platform in a Postoperative Hand Surgery Population.

PURPOSE: Reliable collection of postoperative patient-reported outcome measures (PROMs) is critical to understanding surgical outcomes and the value of care. Automated PROMs collection, triggered by the electronic medical record at the 1-year postoperative anniversary, may provide a simple way to acquire outcomes for patients who have been discharged from clinic. The purposes of this study were to (1) evaluate the percentage of responses with an automated PROMs collection platform and (2) identify whether such a system may introduce selection bias by comparing responders with nonresponders. METHODS: Adult patients (aged ≥18 years) undergoing hand and upper-extremity surgeries between August 2017 and January 2019 were included. Preoperative Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) scores were collected using tablet computer. Postoperative QuickDASH scores were collected using a single electronic survey request 1 year after surgery via an email with a personalized REDCap link. Univariate and multivariable regression analyses were performed to identify factors that differed between responders and nonresponders. RESULTS: A response rate of 27% (269 of 1010) was observed for the eligible postoperative patients. On multivariable analysis, the following were associated with greater odds of response: older age, Caucasian race (vs unknown), longer surgery duration, attending the first postoperative visit, and responding to the preoperative QuickDASH. CONCLUSIONS: The poor response rate that was observed highlights that an automated single email postoperative contact for PROMs collection is insufficient-active follow-up via reminder emails and/or telephone calls is needed. Outcome researchers and clinicians must be aware of potential selection biases, such as age and race, that may exist with automated PROMs collection. CLINICAL RELEVANCE: Single email postoperative contact to obtain postoperative PROMs is insufficient.

The Effect of Social Deprivation on Patient Satisfaction in Otolaryngology Clinics.

OBJECTIVES: Multiple factors have been associated with lower satisfaction scores. We hypothesize that patients with a more deprived socioeconomic status will have different patient satisfaction scores than patients of higher socioeconomic status. METHODS: We reviewed Press Ganey satisfaction scores for new, outpatient visits between January 1, 2014, and December 31, 2018. Due to the high ceiling effects of the survey, "satisfaction" was defined as achieving a perfect score of 100. We determined social deprivation using the 2015 Area Deprivation Index (ADI) which serves as a proxy for socioeconomic status derived from zip codes. Patient satisfaction was defined as a binary variable. Univariate and multivariate binary logistic regression analyses were used to identify factors correlated with patient satisfaction. RESULTS: There were 3239 unique new patients with completed surveys. Univariate analysis demonstrated decreased odds of achieving satisfaction for both the Total Score and Provider Sub-Score for each decile increase in ADI (OR 0.94; CI = 0.908-0.981; P = .003 and OR 0.94; CI = 0.91-0.98; P = .002 respectively). Multivariate analysis revealed the odds for reporting satisfaction for each decile increase in ADI were 0.96 for Total Score (CI = 0.921-0.998; P = .038) and 0.96 for Provider Sub-Score (CI = 0.92-0.993; P = .019). Patients in the most deprived quartile, compared to the least deprived, were significantly less likely to be satisfied with their care for both Total Score (OR 0.70; CI = 0.564-0.865; P = .001) and Provider Sub-Score (OR 0.69; CI = 0.558-0.852; P = .001). CONCLUSIONS: Increased social deprivation was an independent predictor of lower patient satisfaction in otolaryngology outpatients using the Press Ganey survey. This non-modifiable outcome should be taken into consideration when evaluating patient satisfaction scores and offers further support to the need of addressing and improving healthcare discrepancies in the field of otolaryngology.

Factors Associated With Unplanned Reoperation After 4-Corner Arthrodesis: A Study of 478 Wrists.

Purpose: The 4-corner arthrodesis (FCA) is a reliable, motion-sparing technique used to treat scapholunate advanced collapse and scaphoid nonunion advanced collapse arthritis, particularly in stage III wrists in which the capitolunate articulation is compromised. Surgical technique and patient-level variables may influence complications following FCA. We sought to evaluate the rate of complications in a large, combined database and manual chart review study. Methods: Current Procedural Terminology codes were used to search the United States Veteran's Health Administration corporate database to identify wrists treated with FCA over a 24-year period. A retrospective chart review was completed to collect data regarding scapholunate advanced collapse/scaphoid nonunion advanced collapse stage, implant used, the use of a bone graft, smoking status, and comorbidities for all patients undergoing an FCA. A multivariable cox proportional hazards regression was used to assess hazard ratios for reoperation. Incidence rates and the standard error of the mean for reoperation and conversion to total wrist fusion were calculated after grouping patients by 10-year age categories. Results: A total of 478 wrists underwent FCA during the study period, with a mean follow-up of 63 months. Seventy-three (16%) wrists required reoperation. The most frequent secondary procedures included unplanned implant removal (8.2%), total wrist arthrodesis (4.6%), and revision FCA (1.7%). Positive smoking history increased the risk of reoperation, whereas posterior interosseous nerve neurectomy, arthritis stage, and fixation type did not have a statistically significant association with reoperation. Younger age demonstrated an increased incidence of overall reoperation and wrist fusion. Conclusions: The most common reason for reoperation after FCA was implant removal. Smoking history is associated with increased rates of reoperation and wrist arthrodesis. Knowledge of these factors may assist with accurately counseling and indicating patients for FCA. Type of study/level of evidence: Therapeutic III.

Risk of Total Wrist Arthrodesis Following Proximal Row Carpectomy: An Analysis of 1,070 Patients.

PURPOSE: Proximal row carpectomy (PRC) is a motion-sparing procedure with good patient-reported and clinical outcomes. Although some studies have investigated the risk of conversion to total wrist arthrodesis (TWA) after PRC, additional larger studies evaluating the specific risk factors that lead to failure are required. This study aimed to investigate the patient and procedure factors that are associated with increased risk for conversion to TWA in a large cohort of patients who underwent PRC. METHODS: The current procedural technology codes identified patients in a National Veteran's Health database undergoing a PRC over a 26-year period. Risk factors of interest comprised age, posterior interosseous nerve neurectomy, wrist arthritis pattern, bilateral surgery, smoking, comorbidities, and preoperative opioid use. The primary outcome was the rate of conversion to TWA. Cox proportional hazard regression was used to create hazard ratios of selected factors for reoperation. RESULTS: There were 1,070 PRCs performed, with a mean follow-up of 79.8 ± 59.6 months. A total of 5.3% (57/1,070) wrists underwent conversion to TWA. Younger age at the time of PRC (<50 years) significantly increased the risk of TWA (hazard ratio, 3.8; 95% confidence interval, 2.2-6.6). With every 1-year increase in age, there was a reduction of 4% (hazard ratio, 0.96; 95% confidence interval: 0.94-0.98) in the hazard of conversion to TWA. No other factors, including concomitant posterior interosseous nerve neurectomy or bilateral PRC, increased the risk of conversion to TWA. CONCLUSIONS: Proximal row carpectomy is a motion-preserving salvage procedure with a low rate of conversion to wrist arthrodesis. Younger patient age increases the risk of conversion to arthrodesis, whereas posterior interosseous nerve neurectomy, bilateral PRCs, and comorbidity status do not appear to have an impact on the risk of arthrodesis. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Evaluating Factors That Influence Patient Satisfaction in Otolaryngology Clinics.

OBJECTIVES: To identify factors that influence patient satisfaction during outpatient visits in various settings of otolaryngology clinics in an academic medical center. STUDY DESIGN: Retrospective review. SETTING: Academic medical center. METHODS: We reviewed Press Ganey patient satisfaction survey responses for new, outpatient visits between January 1, 2014 and December 31, 2018. Self-reported race was identified using electronic medical records. Multivariate binary logistic regression analyses were used to identify continuous and categorical variables associated with patient satisfaction. RESULTS: There were 3998 unique new patient visits with completed surveys. Multivariate analysis revealed that responses for patients <18 years old are less likely to be satisfied with their care compared to patients ≥18 years old (OR 0.66; P < .001). For each 10-minute increase in wait time, patients were 43.4% less likely report satisfaction (P < .001). African American patients were also less likely to report satisfaction (OR 0.22; P = .043) while Native Hawaiian and Pacific Islanders were over 3 times more likely to be satisfied (OR 3.6; P = .013). Additionally, Medicare patients and those who were seen at community satellite clinics compared to the main University Hospital had increased odds of achieving satisfactory care (OR 1.3; P = .005 and OR 1.3; P = .002, respectively). CONCLUSIONS: Wait time, clinic location, patient race, insurance provider, and age were all shown to significantly influence patient-reported satisfaction. Understanding how these variables influence patient satisfaction will hopefully lead to processes that improve patient satisfaction. LEVEL OF EVIDENCE: Level 3.

Evaluation of Factors Affecting Return to Work Following Carpal Tunnel Release: A Statewide Cohort Study of Workers' Compensation Subjects.

PURPOSE: Most randomized trials comparing open carpal tunnel release (OCTR) to endoscopic carpal tunnel release (ECTR) are not specific to a working population and focus mainly on how surgical technique has an impact on outcomes. This study's primary goal was to evaluate factors affecting days out of work (DOOW) following carpal tunnel release (CTR) in a working population and to evaluate for differences in medical costs, indemnity payments, disability ratings, and opioid use between OCTR and ECTR with the intent of determining whether one or the other surgical method was a determining factor. METHODS: Using the Ohio Bureau of Workers' Compensation claims database, individuals were identified who underwent unilateral isolated CTR between 1993 and 2018. We excluded those who were on total disability, who underwent additional surgery within 6 months of their index CTR, including contralateral or revision CTR, and those not working during the same month as their index CTR. Outcomes were evaluated at 6 months after surgery. Multivariable linear regression was performed to evaluate covariates associated with DOOW. RESULTS: Of the 4596 included participants, 569 (12.4%) and 4027 (87.6%) underwent ECTR and OCTR, respectively. Mean DOOW were 58.4 for participants undergoing OCTR and 56.6 for those undergoing ECTR. Carpal tunnel release technique was not predictive of DOOW. Net medical costs were 20.7% higher for those undergoing ECTR. Multivariable linear regression demonstrated the following significant predictors of higher DOOW: preoperative opioid use, legal representation, labor-intensive occupation, increasing lag time from injury to filing of a worker's compensation claim, and female sex. Being married, higher income community, and working in the public sector were associated with fewer DOOW. CONCLUSIONS: In a large statewide worker's compensation population, demographic, occupational, psychosocial, and litigatory factors have a significant impact on DOOW following CTR, whereas differences in surgical technique between ECTR and OCTR did not. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.

Evaluation of factors impacting patient satisfaction in a pediatric otolaryngology clinic.

OBJECTIVES: With an emphasis on patient-centered care and provider transparency, patient satisfaction measures have become a key indicator of healthcare quality. Using the Press Ganey Outpatient Medical Practice Survey (PGOMPS), we sought to determine key factors that impact patient satisfaction. METHODS: We conducted a retrospective review of new pediatric (<18 years old) outpatient otolaryngology visits between January 1, 2014 and December 31, 2018 at a children's hospital clinic and satellite clinics. Univariate and multivariate binary logistic regression analysis were used to determine factors correlated with patient satisfaction for both the PGOMPS Total Score and Provider Sub-Score. RESULTS: A total of 1,050 patient or parent responses were included. The mean patient age was 5.6 ± 5.0 years with 54.7% identified as male. Univariate analysis demonstrated that for each 10-min increase in Total Wait Time, the odds of being satisfied were significantly decreased on both the Total Score (odds ratio [OR] 0.5; P < 0.001) and Provider Sub-Score (OR 0.8; P < 0.001). Furthermore, for each additional 5-year increase in patient age, patients were significantly more likely to report satisfaction on Total Score (OR 1.21; P = 0.011). Multivariate analysis revealed that the odds of achieving satisfaction for each decile increase in Total Wait Time were 0.5 for Total Score (P < 0.001) and 0.8 for Provider Sub-Score (P < 0.001), independent of patient age, sex, insurance category, socioeconomic disadvantage level, and patient community type. CONCLUSIONS: Wait time is a significant factor impacting patients' likelihood of being satisfied with their overall care in a pediatric otolaryngology clinic setting.

Establishing the Substantial Clinical Benefit in a Non-Shoulder Hand and Upper Extremity Population for the QuickDASH and PROMIS Upper Extremity and Physical Function Computer Adaptive Tests.

PURPOSE: It is unclear what score changes on the abbreviated Disabilities of the Arm, Hand, and Shoulder (QuickDASH), Patient-Reported Outcomes Measurement Information System (PROMIS) upper extremity (UE) computer adaptive test (CAT), and PROMIS physical function (PF) CAT represent a substantial improvement. We calculated the substantial clinical benefit (SCB) for these 3 instruments in a non-shoulder hand and upper extremity population. METHODS: Adult patients treated between March 2015 and September 2019 at a single academic tertiary institution were identified. The QuickDASH, PROMIS UE CAT v2.0, and PROMIS PF CAT v2.0 scores were collected using a tablet computer. Responses to the QuickDASH both at baseline and follow-up 6 ± 4 weeks later, and a response to the anchor question "Compared to your first evaluation at the University Orthopaedic Center, how would you describe your physical function level now?" were required for inclusion. A second anchor question querying treatment-related improvement was also used. The SCB was calculated using an anchor-based approach comparing the mean change difference between groups reporting no change and a maximal change for both anchor questions. RESULTS: Of 1,119 included participants, the mean age was 48 ± 17 years, 53% were women, and half were recovering from surgery. Score changes between baseline and follow-up were significantly different between groups reporting no improvement and maximal improvement on both anchor questions. The SCB values ranged between 16.9 and 22.8 on the QuickDASH, 5.9 and 7.1 on the UE CAT, and 3.5 and 6.7 on the PF CAT. CONCLUSIONS: These score improvements for the QuickDASH, UE CAT, and PF CAT represent a substantial clinical improvement in a non-shoulder hand and upper extremity population. CLINICAL RELEVANCE: These SCB estimates may assist with the interpretation of outcome scores at a population level.

Cost Assessment of Plating Versus Tension Band Wiring Constructs for Treating Mayo Type 2A Olecranon Fractures.

PURPOSE: Tension band wiring (TBW) or plating may be used for fixation with similar clinical outcomes for adults with displaced Mayo 2A olecranon fractures. The primary hypothesis is that total direct costs (TDCs) for surgery are lower for TBW than plating. Our secondary hypothesis is that combined surgical TDCs are lower for TBW even with a 100% rate of subsequent tension band hardware removal and a 0% rate of plate removal. METHODS: Patients who underwent TBW or plating of an isolated unilateral Mayo 2A olecranon fracture between July 2011 and January 2020 at a single academic medical center were identified. Then, TDC for each surgery on plate fixation, TBW, and hardware removal was obtained and converted to 2020 US dollars using information technology cost tools provided by our institution. Finally, relative TDCs were compared between plate fixation and TBW groups using univariate and multivariable generalized estimating equations with log-link. RESULTS: Of the 97 included patients, the mean age was 50 ± 21 years, and 48% were female. Tension band wiring and plate fixation were performed on 18% (17/97) and 82% (80/97) of male and female patients, respectively. Demographics were similar between groups, although the finding that plate fixation cost 2.6 times that of TBW within the index surgery was significant in the multivariable model, independent of potential confounders (coefficient 2.55, 95% confidence interval: 2.09-3.10). Additionally, mean TDC remained significantly greater for plate fixation even under the hypothetical situation where 100% TBW were removed, and the plate removal rate was 0% (cost difference 181%). CONCLUSIONS: Using TBW relative to plate fixation may improve the cost of care for operative Mayo 2A olecranon fractures. Furthermore, this finding was robust to the rate of hardware removal. TYPE OF STUDY/LEVEL OF EVIDENCE: Economic and Decision Analyses III.

Recommendation of Surgery and Other Interventions Is Associated With Increased Patient Satisfaction With Orthopedic Outpatient Visits.

The primary goal of our study was to determine whether satisfaction with orthopedic surgery outpatient visits is affected by a recommendation for surgery compared with a recommendation for nonoperative treatment, as measured by the Press Ganey Outpatient Medical Practice Survey (PGOMPS). Secondarily, we evaluated the effect of offering an injection, therapy, or any intervention (surgery, injection, therapy, immobilization, aspiration, or radiation therapy) on PGOMPS scores. To investigate this relationship, we reviewed new orthopedic outpatient visits at a tertiary academic center during a single year (2018). Patient satisfaction was defined as a PGOMPS score greater than the 33rd percentile. Univariate and multivariate binary logistic regression was conducted to determine the effect of a surgical recommendation and the effect of recommending an injection, therapy, or any intervention on the PGOMPS total score and provider subscore. Of the 1217 included patients, multivariate analysis showed that a surgical recommendation was significantly and independently associated with satisfaction on the PGOMPS total score and provider subscore. Multivariate analysis also showed that being offered an injection, therapy, or any intervention was significantly associated with higher PGOMPS total scores compared with not being offered those interventions. Patients who were offered surgery or other interventions were significantly more likely to be satisfied with their encounter and the surgeon. Patients who were offered surgery were significantly more likely to be satisfied with their encounter and the surgeon than those who were not offered surgery. Additionally, patients who were offered any intervention were significantly more likely to be satisfied with their encounter than those who were not offered an intervention.

Scaphotrapeziotrapezoid Arthrodesis: Systematic Review.

PURPOSE: Scaphotrapeziotrapezoid (STT) arthrodesis surgery is used for various types of wrist pathologies. The objective of our study was to perform a systematic review of complications and outcomes after STT arthrodesis. METHODS: Several major databases were used to perform a systematic literature review in order to obtain articles reporting complications and outcomes following STT arthrodesis. The primary purpose was to identify rates of nonunion and conversion to total wrist arthrodesis. Secondary outcomes included wrist range of motion, grip strength, and Disabilities of the Arm Shoulder and Hand scores. A multivariable analysis was performed to evaluate factors associated with the primary and secondary outcomes of interest. RESULTS: Out of the 854 records identified in the primary literature search, 30 studies were included in the analysis. A total of 1,429 procedures were performed for 1,404 patients. The pooled nonunion rate was 6.3% (95% CI, 3.5-9.9) and the rate of conversion to total wrist arthrodesis following the index STT was 4.2% (95% CI, 2.2-6.7). The mean pooled wrist flexion was 40.7° (95% CI, 30.8-50.5) and extension was 49.7° (95% CI, 43.5-55.8). At final follow-up, the mean pooled grip strength was 75.9% (95% CI, 69.3-82.5) of the nonsurgical contralateral hand. Compared with all other known indications, Kienbock disease had a statistically significant lower nonunion rate (14.1% vs 3.3%, respectively). Mixed-effects linear regression using patient-level data revealed that increasing age was significantly associated with complications, independent of occupation and diagnosis. CONCLUSIONS: Our study demonstrated a low failure rate and conversion to total wrist arthrodesis after STT arthrodesis and acceptable postoperative wrist range of motion and strength when compared to the contralateral hand. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Cost Implications of Varying the Surgical Setting and Anesthesia Type for Dorsal Wrist Ganglion Cyst Excision Surgery.

BACKGROUND: Minimizing expenses attributed to dorsal wrist ganglion cyst excisions, a common minor surgical procedure, presents potential for health care cost savings. Varying the surgical setting (operating room versus procedure room) and type of anesthesia (local-only, monitored anesthesia care, or monitored with regional or general anesthesia) may affect total operative costs. METHODS: Patients who underwent an isolated unilateral dorsal wrist ganglion cyst excision between January of 2014 and October of 2019 at a single academic medical center were identified by CPT code. The total direct costs for each surgical encounter that met inclusion criteria were calculated. The relative total direct costs were compared between surgical setting and anesthesia type groups. Univariate and multivariable gamma regression models were used to identify factors associated with surgical costs. RESULTS: A total of 192 patients were included; 26 cases (14 percent) were performed in the procedure room and 166 cases (86 percent) were performed in the operating room. No significant differences in demographic factors were identified between groups. Univariate analysis demonstrated that use of operating room/monitored anesthesia care, operating room/monitored anesthesia care with regional anesthesia, and operating room/general anesthesia groups, as compared to procedure room/local-only, yielded significantly greater median costs (1.76-, 2.34-, and 2.44-fold greater, respectively). Multivariable analysis demonstrated 1.80-, 2.10-, and 2.31-fold greater costs with use of operating room/monitored anesthesia care, operating room/monitored anesthesia care with regional anesthesia, and operating room/general anesthesia relative to procedure room/local-only, respectively. CONCLUSION: Performing dorsal wrist ganglion cyst excisions in a procedure room with local-only anesthesia minimizes operative direct costs relative to use of the operating room and other anesthetic types.

Scaphotrapeziotrapezoid Arthrodesis: A 10-Year Follow-up Study of Complications in 58 Wrists.

BACKGROUND: Scaphotrapeziotrapezoid (STT) arthrodesis is a procedure used for specific degenerative arthritis and instability patterns of the wrist. This study evaluates nonunion rate and risk factors for reoperation after STT arthrodesis in the Veterans Affairs Department patient population. The purpose of our study was to assess the long-term nonunion rate following STT arthrodesis and to identify factors associated with reoperation. METHODS: The national Veterans Health Administration Corporate Data Warehouse and Current Procedural Terminology codes identified STT arthrodesis procedures from 1995 to 2016. Frequencies of total wrist arthrodesis (TWA) and secondary operations were determined. Univariate analyses provided odds ratios for risk factors associated with complications. RESULTS: Fifty-eight STT arthrodeses were performed in 54 patients with a mean follow-up of 120 months. Kirschner wires (K-wires) were the most common fixation method (69%). Six wrists (10%) required secondary procedures: 5 TWAs and 1 revision STT arthrodesis. Four patients underwent additional procedures for nonunion (7%). Twenty-four patients required K-wire removal, 8 (14%) of these in the operating room, which were not included in regression analysis. Every increase in 1 year of age resulted in a 15% decrease in likelihood of reoperation (95% confidence interval: 0.77-0.93; P < .0001). Opioid use within 90 days before surgery (P = 1.00), positive smoking history (P = 1.00), race (P = .30), comorbidity count (P = .25), and body mass index (P = .19) were not associated with increased risk of reoperation. CONCLUSIONS: At a mean follow-up of 10 years, patients undergoing STT arthrodesis have a 10% risk of reoperation, and this risk decreases with older patient age. There was a symptomatic nonunion rate of 7%, similar to prior published rates. Patient demographics, comorbidity, smoking history, and opioid use did not appear to increase risk of reoperation.

Evaluation of Risk Factors for Loss of Acceptable Alignment for Distal Radius Fractures That Are Nondisplaced or Minimally Displaced on Initial Presentation.

PURPOSE: Numerous studies have evaluated risk factors for loss of acceptable radiographic alignment, as described by the American Academy of Orthopaedic Surgeons Clinical Practice Guidelines (CPG), following closed reduction of distal radius fractures (DRFs). Less is known about DRFs that are well aligned on initial presentation and do not require closed reduction. We evaluated the rate of and risk factors for displacement of DRFs that are nondisplaced or minimally displaced on initial presentation. METHODS: This retrospective cohort study identified patients with nondisplaced or minimally displaced DRFs seen at a single academic tertiary center between 2015 and 2019. DRFs that required a reduction or initial surgical treatment based on the American Academy of Orthopaedic Surgeons CPG and those with a volar shear pattern were excluded. We recorded standard radiographic measurements on presentation and wrist radiographs after 6 weeks. Univariate and binary multivariable logistic regression analyses evaluated associations between sex, age, the presence of dorsal comminution, intra-articular involvement, associated ulnar fractures, and minimal displacement (vs nondisplacement on initial radiographs) with loss of acceptable alignment. RESULTS: Of the 110 included patients, 72% were female and the mean age was 52 years (SD, 17 years). Overall, 33 (30%) had displacement beyond the AAOS CPG criteria at 6 weeks. A multivariable analysis demonstrated that the presence of dorsal comminution (odds ratio, 37.8) and age >60 years (odds ratio, 3.6) were significantly associated with loss of acceptable alignment, whereas sex, intra-articular involvement, associated ulnar styloid/neck fractures, and minimal displacement were not associated. CONCLUSIONS: For DRFs that were initially nondisplaced or minimally displaced, the overall rate of unacceptable radiographic displacement at 6 weeks was 30%. Dorsal comminution and age >60 years were both independently associated with displacement, suggesting that patients with these risk factors may warrant closer follow-up than those without risk factors. TYPE OF STUDY/LEVEL OF EVIDENCE: Diagnostic IV.

The minimal clinically important difference of the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function and upper extremity computer adaptive tests and QuickDASH in the setting of elbow trauma.

BACKGROUND: Minimal clinically important difference (MCID) estimates are useful for gauging clinical relevance when interpreting changes or differences in patient-reported outcomes scores. These values are lacking in the setting of elbow trauma. Our primary purpose was to estimate the MCID of the Patient-Reported Outcomes Measurement Information System (PROMIS) physical function (PF) computer adaptive test (CAT), the PROMIS upper extremity (UE) CAT, and the QuickDASH using an anchor-based approach for patients recovering from elbow trauma and related surgeries. Secondarily, we aimed to estimate the MCID using the 1/2 standard deviation method. MATERIALS & METHODS: Adult patients undergoing treatment for isolated elbow injuries between July 2014 and April 2020 were identified at a single tertiary academic medical center. Outcomes, including the PROMIS PF CAT v1.2/2.0, PROMIS UE CAT v1.2, and QuickDASH, were collected via a tablet computer. For inclusion, baseline (6 months before injury up to 11 days postoperatively or after injury) and follow-up (11 to 150 days postoperative or after injury) PF or UE CAT scores were required, as well as a response to an anchor question querying improvement in physical function. The MCID was calculated using (1) an anchor-based approach using the difference in mean score change between anchor groups reporting "No change" and "Slightly Improved/Improved" and (2) the 1/2 standard deviation method. RESULTS: Of the 146 included patients, the mean age was 46 ± 18 years and 67 (46%) were women. Most patients (129 of 146 or 88%) were recovering from surgery, and the remaining 12% were recovering from nonoperatively managed fractures and/or dislocations. The mean follow-up was 157 ± 192 days. Scores for each instrument improved significantly between baseline and follow-up. Anchor-based MCID values were calculated as follows: 5.7, 4.6, and 5.3 for the PROMIS PF CAT, PROMIS UE CAT, and QuickDASH, respectively. MCID values estimated using the 1/2 standard deviation method were 4.3, 4.8, and 11.7 for the PROMIS PF CAT, PROMIS UE CAT, and QuickDASH, respectively. CONCLUSIONS: In the setting of elbow trauma, we propose MCID ranges of 4.3 to 5.7 for the PROMIS PF CAT, 4.6 to 4.8 for the PROMIS UE CAT, and 5.3 to 11.7 for the QuickDASH. These values will provide a framework for clinical relevance when interpreting clinical outcomes studies, or powering clinical trials, for populations recovering from trauma.

Evaluating the Impact of Social Deprivation on Mid-Term Outcomes Following Distal Radius Open Reduction Internal Fixation.

PURPOSE: Although baseline biopsychosocial factors are associated with short-term patient-reported outcomes following distal radius fracture open reduction internal fixation (ORIF), their effect on mid-term outcomes is unclear. We aimed to evaluate the effect of social deprivation, previously established as a surrogate for depression, pain interference, and anxiety, on quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) scores >1 year following distal radius ORIF. METHODS: Adult patients (≥18 years) with an isolated distal radius fracture treated with ORIF by orthopedic trauma and hand surgeons at a single tertiary academic center over a 3-year period were included. Outcomes at ≥1 year postoperatively were evaluated using QuickDASH. Age, follow-up duration, area deprivation index (ADI; a measure of social deprivation), subspecialty (hand vs trauma), and postoperative alignment were assessed using linear regression with 95% confidence intervals after bootstrapping and a permutation test for P values to test for their association with the final QuickDASH score. RESULTS: Follow-up data were obtained for 98 of 220 (44.5%) patients at a mean of 3.1 ± 1.0 years after surgery. Mean age and ADI were 53.2 ± 15.4 years and 26.8 ± 18.7, respectively. Most fractures were intra-articular (67.3%), and 72.4% had acceptable postoperative alignment parameters, as defined by the American Academy of Orthopaedic Surgeons clinical practice guidelines. The mean QuickDASH score was 13.0 ± 16.5. There were no significant associations between the final QuickDASH score and any studied factor, including ADI, as determined using univariable analysis. Multivariable analysis showed no association between ADI and the final QuickDASH score, independent of age, sex, treating service, follow-up duration, and fracture alignment or pattern. CONCLUSIONS: At mid-term follow up after distal radius ORIF, ADI did not correlate with QuickDASH scores, and the QuickDASH scores of the patients did not differ from those of the general population. However, our cohort mostly comprised patients with levels of deprivation below the national median. Although studies have shown that the short-term outcomes of distal radius ORIF are influenced by biopsychosocial factors, outcomes at the time of final recovery may not be associated with social deprivation. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic IV.

Prognostic Factors Affecting Long-Term Outcomes After Elbow Dislocation: A Longitudinal Cohort Study.

PURPOSE: To describe patient-reported outcomes following simple elbow dislocation and to identify the baseline factors that predict outcomes. METHODS: Adult patients treated with a closed reduction for a simple elbow dislocation with or without minor fracture (coronoid avulsion, radial head fracture, or epicondyle avulsion) from 2000 to 2018 completed outcome instruments including Disabilities of the Arm, Shoulder and Hand (QuickDASH) via Research Electronic Data Capture. Descriptive statistics were calculated. Univariate followed by multivariate Tobit regression models were used to determine factors associated with clinical outcomes on QuickDASH. Social deprivation was measured using the Area Deprivation Index. Patients with additional upper-extremity injuries or associated major fractures (Monteggia or terrible triad injuries, distal humerus fractures, etc) were excluded. RESULTS: At a mean follow-up of 67.5 months, 95% (38/40) of patients reported satisfaction with treatment, and clinical outcomes were good (QuickDASH 9.0 ± 14.8). Univariate analysis showed that higher Area Deprivation Index, older age, female sex, high-energy mechanism of injury, and worker's compensation (WC) or Medicare insurance status (vs commercial) was associated with significantly worse QuickDASH scores at follow-up. Early therapy, dominant elbow involvement, presence of minor fractures (minimally displaced radial head, coronoid tip, or epicondylar avulsion fractures), race, and treating service did not influence outcomes in univariate analyses. Multivariate analysis demonstrated a significant association between increased social deprivation, WC insurance, and Medicare insurance and worse QuickDASH scores while controlling for new upper-extremity injury, age, sex, and mechanism of injury. CONCLUSIONS: Outcomes and treatment satisfaction following simple elbow dislocation are generally good but are significantly worse for the patients with greater levels of social deprivation and WC or Medicare insurance. Although surgeons should be aware of the possibility that specific subsets of patients may benefit from early therapy, this factor did not appear to influence long-term outcomes in this small cohort.

Optimizing Costs and Outcomes for Carpal Tunnel Release Surgery: A Cost-Effectiveness Analysis from Societal and Health-Care System Perspectives.

BACKGROUND: It is unclear which carpal tunnel release (CTR) strategy (i.e., which combination of surgical technique and setting) is most cost-effective. A cost-effectiveness analysis was performed to compare (1) open CTR in the procedure room (OCTR/PR), (2) OCTR in the operating room (OCTR/OR), and (3) endoscopic CTR in the operating room (ECTR/OR). METHODS: A decision analytic model was used to compare costs and health utilities between treatment strategies. Utility and probability parameters were identified from the literature. Medical costs were estimated with Medicare ambulatory surgical payment data. Indirect costs were related to days out of work due to surgical recovery and complications. The effectiveness outcome was quality-adjusted life years (QALYs). Probabilistic sensitivity analyses and one-way sensitivity analyses were performed. Cost-effectiveness was assessed from the societal and health-care system perspectives with use of a willingness-to-pay threshold of $100,000/QALY. RESULTS: In the base-case analysis, OCTR/PR was more cost-effective than OCTR/OR and ECTR/OR from the societal perspective. The mean total costs and QALYs per patient were $29,738 ± $4,098 and 0.88 ± 0.08 for OCTR/PR, $30,002 ± $4,098 and 0.88 ± 0.08 for OCTR/OR, and $41,311 ± $4,833 and 0.87 ± 0.08 for ECTR/OR. OCTR/PR was also the most cost-effective strategy from the health-care system perspective. These findings were robust in the probabilistic sensitivity analyses: OCTR/PR was the dominant strategy (greater QALYs at a lower cost) in 55% and 61% of iterations from societal and health-care system perspectives, respectively. One-way sensitivity analysis demonstrated that OCTR/PR and OCTR/OR remained more cost-effective than ECTR/OR from a societal perspective under the following conditions: $0 surgical cost of ECTR, 0% revision rate following ECTR, equalization of the return-to-work rate between OCTR and ECTR, or 0 days out of work following ECTR. OCTR/OR became more cost-effective than OCTR/PR with the median nerve injury rate tripling and doubling from societal and health-care system perspectives, respectively, or if surgical direct costs in the PR exceeded those in the OR. CONCLUSIONS: Compared with OCTR/OR and ECTR/OR, OCTR/PR minimizes costs to the health-care system and society while providing favorable outcomes.

Comparison of direct surgical cost for humeral shaft fracture fixation: open reduction internal fixation versus intramedullary nailing.

BACKGROUND AND/OR HYPOTHESIS: Prior literature has supported similar complication rates and outcomes for humeral shaft fractures treated with open reduction internal fixation (ORIF) with a plate/screw construct versus intramedullary nailing (IMN). The purpose of this study is to determine whether surgical encounter total direct costs (SETDCs) differ between ORIF and IMN for these fractures. METHODS: Adult patients (≥ 18 years) treated for isolated humeral shaft fractures by ORIF or IMN between June 18, 2014 and June 17, 2019 at a single tertiary academic center were available for inclusion. SETDCs for ORIF and IMN groups, obtained through our institution's information technology value tool, were adjusted to 2019 US dollars and converted to relative costs per institutional policy. SETDCs for ORIF and IMN were compared using the Wilcoxon rank-sum test. RESULTS: Demographic factors did not differ between ORIF and IMN cohorts with the exception of age (mean of 18.6 years older for IMN; P < .001) and American Society of Anesthesiologist class (higher for IMN; P = .029). Substantial cost variation was observed among the 39 included ORIF and 21 IMN cases. Costs pertaining to operating room utilization (P = .77), implants (P = .64), and the recovery room (P = .27) were similar for ORIF and IMN, whereas supply costs were significantly greater for IMN with a median (interquartile range) of 0.21 (0.17 ∼ 0.28), more than twice the supply costs of ORIF (0.09 [0.05 ∼ 0.13], P < .001). The SETDC of IMN was significantly greater than that of ORIF (median [interquartile range]:1.00 [0.9 to 1.13] vs. 0.83 [0.71∼1.05], respectively; P = .047). DISCUSSION AND/OR CONCLUSION: Our study found that the SETDC for humeral shaft fracture fixation was greater for IMN than for ORIF, although patient cohorts differed significantly with respect to age and the American Society of Anesthesiologist class. Surgeons should take these findings into consideration when consenting patients with humeral shaft fractures for the appropriate fixation type.
