Biomechanical evaluation of subscapularis peel repairs augmented with the long head of the biceps tendon for anatomic total shoulder arthroplasty.

BACKGROUND: Subscapularis failure is a troublesome complication following anatomic total shoulder arthroplasty (aTSA). Commonly discarded during aTSA, the long head of the biceps tendon (LHBT) may offer an efficient and cheap autograft for the augmentation of the subscapularis repair during aTSA. The purpose of this study was to biomechanically compare a standard subscapularis peel repair to 2 methods of subscapularis peel repair augmented with LHBT. METHODS: 18 human cadaveric shoulders (61 ± 9 years of age) were used in this study. Shoulders were randomly assigned to biomechanically compare subscapularis peel repair with (1) traditional single-row repair, (2) single row with horizontal LHBT augmentation, or (3) single row with V-shaped LHBT augmentation. Shoulders underwent biomechanical testing on a servohydraulic testing system to compare cyclic displacement, load to failure, and stiffness. RESULTS: There were no significant differences in the cyclic displacement between the 3 techniques in the superior, middle, or inferior portion of the subscapularis repair (P > .05). The horizontal (436.7 ± 113.3 N; P = .011) and V-shape (563.3 ± 101.0 N; P < .001) repair demonstrated significantly greater load to failure compared with traditional repair (344.4 ± 82.4 N). The V-shape repair had significantly greater load to failure compared to the horizontal repair (P < .001). The horizontal (61.6 ± 8.4 N/mm; P < .001) and the V-shape (62.8 ± 6.1; P < .001) repairs demonstrated significantly greater stiffness compared to the traditional repair (47.6 ± 6.2 N). There was no significant difference in the stiffness of the horizontal and V-shape repairs (P = .770). CONCLUSIONS: Subscapularis peel repair augmentation with LHBT autograft following aTSA confers greater time zero load to failure and stiffness when compared to a standard subscapularis peel repair.

Suture Tape Augmentation for the Repair of Index Finger Radial Collateral Ligament Injury: A Biomechanical Study.

PURPOSE: Despite their clinical importance in maintaining the stability of the pinch mechanism, injuries of the radial collateral ligament (RCL) of the index finger may be underrecognized and underreported. The purpose of this biomechanical study was to compare the repair of index finger RCL tears with either a standard suture anchor or suture tape augmentation. METHODS: The index fingers from 24 fresh-frozen human cadavers underwent repair of torn RCLs using either a standard suture anchor or suture tape augmentation. Following the repairs, the initial displacement of the repair with a 3-N ulnar deviating load was evaluated. Next, the change in displacement (cyclic deformation) of the repair after 1,000 cycles of 3 N of ulnar deviating force was calculated (displacement of the 1000th cycle - displacement of the first cycle). Finally, the amount of force required to cause clinical failure (30° ulnar deviation) of the repair was determined. RESULTS: Suture tape augmentation repairs displayed significantly less cyclic deformation (0.8 ± 0.5 mm) after cyclic loading than suture anchor repairs (1.8 ± 0.7 mm). There was no significant difference in the force required to cause the clinical failure of the repairs between the suture tape (35.1 ± 18.1 N) and suture anchor (24.5 ± 9.2 N) repairs. CONCLUSIONS: Index finger RCL repair with suture tape augmentation results in decreased deformation with repetitive motion compared with RCL repair alone. CLINICAL RELEVANCE: Suture tape augmentation may allow for early mobilization following index finger RCL repair by acting as a brace that protects the repaired ligament from deforming forces.

Bicortical suspensory button fixation yields greater ultimate load to failure over unicortical all-suture anchor fixation in distal biceps brachii tendon repair.

BACKGROUND: Various distal biceps tendon repair techniques exist, each with their own biomechanical profile. Recently, all-suture anchor fixation has recently become an intriguing option for distal biceps fixation, compared with the proven track record of the suspensory cortical button. In addition, intramedullary techniques have been utilized as a means to avoid complications such as nerve damage seen with extramedullary fixation. PURPOSE: The purpose of this study is to perform a comparative biomechanical analysis of 4 unique distal biceps tendon fixation methods: Unicortical/intramedullary all-suture anchor fixation (UIAS), Bicortical/extramedullary all-suture anchor fixation (BEAS), Unicortical/intramedullary suspensory button fixation (UISB), and Bicortical/extramedullary suspensory button fixation (BESB). STUDY DESIGN: Controlled Laboratory study. METHODS: 24 fresh-frozen cadaveric elbows were randomized into 4 groups providing data from 6 specimens, with each group undergoing a different repair technique. The specimens underwent 2 studies: Cyclic loading and Ultimate Load to failure (ULTF) testing. The repaired elbows were cycled 3000 times between 0 and 90 degrees of flexion, with displacement under cyclic loading at the repair site measured using a differential variable reductance transducer. ULTF test was performed with the elbow flexed at 90 degrees. The modes of failure were recorded. RESULTS: The mean cyclic displacements between the 4 groups were as follows: UIAS: 1.45 ± 1.04 mm; BEAS: 2.75 ± 1.32 mm; UISB: 1.45 ± .776 mm; BESB: 2.66 ± 1.18 mm (p= 0.077). Bicortical repairs displayed greater displacement after cyclic loading when compared with unicortical repairs regardless of anchor used (p= 0.007). The mean ULTF for each group was as follows: all-suture intramedullary: 200 N; all-suture extramedullary: 330 N; cortical-button intramedullary: 256 N; cortical-button extramedullary: 342 N). All-suture unicortical/intramedullary repair had a significantly lower ULTF (200 N) compared with cortical-button Bicortical/extramedullary repair (342 N) (p=0.043). CONCLUSION: Bicortical/extramedullary suspensory button fixation demonstrated a greater ultimate load to failure when compared with unicortical/intramedullary all-suture anchor fixation. These findings suggest that bicortical/extramedullary suspensory cortical button fixation is a biomechanically superior construct as compared to unicortical/intramedullary all-suture anchor fixation. However, there was no significant difference in ULTF between extra-medullary, Bicortical button or Bicortical, all-suture anchor fixation.

Operationalizing the 'pragmatic' measures construct using a stakeholder feedback and a multi-method approach.

CONTEXT: Implementation science measures are rarely used by stakeholders to inform and enhance clinical program change. Little is known about what makes implementation measures pragmatic (i.e., practical) for use in community settings; thus, the present study's objective was to generate a clinical stakeholder-driven operationalization of a pragmatic measures construct. EVIDENCE ACQUISITION: The pragmatic measures construct was defined using: 1) a systematic literature review to identify dimensions of the construct using PsycINFO and PubMed databases, and 2) interviews with an international stakeholder panel (N = 7) who were asked about their perspectives of pragmatic measures. EVIDENCE SYNTHESIS: Combined results from the systematic literature review and stakeholder interviews revealed a final list of 47 short statements (e.g., feasible, low cost, brief) describing pragmatic measures, which will allow for the development of a rigorous, stakeholder-driven conceptualization of the pragmatic measures construct. CONCLUSIONS: Results revealed significant overlap between terms related to the pragmatic construct in the existing literature and stakeholder interviews. However, a number of terms were unique to each methodology. This underscores the importance of understanding stakeholder perspectives of criteria measuring the pragmatic construct. These results will be used to inform future phases of the project where stakeholders will determine the relative importance and clarity of each dimension of the pragmatic construct, as well as their priorities for the pragmatic dimensions. Taken together, these results will be incorporated into a pragmatic rating system for existing implementation science measures to support implementation science and practice.

Long-Term Functional Outcomes and Athletic Ability in Shoulder Sports After Anatomic Coracoclavicular Ligament Reconstruction for Chronic Type 3 and 5 Acromioclavicular Joint Injuries.

Background: Promising short- and midterm outcomes have been seen after anatomic coracoclavicular ligament reconstruction (ACCR) for chronic acromioclavicular joint (ACJ) injuries. Purpose/Hypothesis: To evaluate long-term outcomes and shoulder-related athletic ability in patients after ACCR for chronic type 3 and 5 ACJ injuries. It was hypothesized that these patients would maintain significant functional improvement and sufficient shoulder-sport ability at a long-term follow-up. Study Design: Case series; Level of evidence, 4. Methods: Included were 19 patients (mean age, 45.9 ± 11.2 years) who underwent ACCR for type 3 or 5 ACJ injuries between January 2003 and August 2014. Functional outcome measures included the American Shoulder and Elbow Surgeons (ASES), Rowe, Constant-Murley, Simple Shoulder Test (SST), and Single Assessment Numeric Evaluation (SANE) scores as well as the visual analog scale (VAS) for pain, which were collected preoperatively and at the final follow-up. Postoperative shoulder-dependent athletic ability was assessed using the Athletic Shoulder Outcome Scoring System (ASOSS). Shoulder activity level was evaluated using the Shoulder Activity Scale (SAS), while the Subjective Patient Outcome for Return to Sports (SPORTS) score was collected to assess the patients' ability to return to their preinjury sporting activity. Results: The mean follow-up time was 10.1 ± 3.8 years (range, 6.1-18.8 years). Patients achieved significant pre- to postoperative improvements on the ASES (from 54.2 ± 22.6 to 83.5 ± 23.1), Rowe (from 66.6 ± 18.1 to 85.3 ± 19), Constant-Murley (from 64.6 ± 20.9 to 80.2 ± 22.7), SST (from 7.2 ± 3.4 to 10.5 ± 2.7), SANE (from 30.1 ± 23.2 to 83.6 ± 26.3), and VAS pain scores (from 4.7 ± 2.7 to 1.8 ± 2.8) (P < .001 for all), with no significant differences between type 3 and 5 injuries. At the final follow-up, patients achieved an ASOSS of 80.6 ± 32, SAS level of 11.6 ± 5.1, and SPORTS score of 7.3 ± 4.1, with no significant differences between type 3 and 5 injuries. Four patients (21.1%) had postoperative complications. Conclusion: Patients undergoing ACCR using free tendon allografts for chronic type 3 and 5 ACJ injuries maintained significant improvements in functional outcomes at the long-term follow-up and achieved favorable postoperative shoulder-sport ability, activity, and return to preinjury sports participation.

Prescription Digital Therapeutics for Substance Use Disorder in Primary Care: Mixed Methods Evaluation of a Pilot Implementation Study.

BACKGROUND: Delivering prescription digital therapeutics (ie, evidence-based interventions designed to treat, manage, or prevent disorders via websites or smartphone apps) in primary care could increase patient access to substance use disorder (SUD) treatments. However, the optimal approach to implementing prescription digital therapeutics in primary care remains unknown. OBJECTIVE: This pilot study is a precursor to a larger trial designed to test whether implementation strategies (practice facilitation [PF] and health coaching [HC]) improve the delivery of prescription digital therapeutics for SUDs in primary care. This mixed methods study describes outcomes among patients in the 2 pilot clinics and presents qualitative findings on implementation. METHODS: From February 10 to August 6, 2021, a total of 3 mental health specialists embedded in 2 primary care practices of the same integrated health system were tasked with offering app-based prescription digital therapeutics to patients with SUD. In the first half of the pilot, implementation activities included training and supportive tools. PF (at 1 clinic) and HC (at 2 clinics) were added in the second half. All study analyses relied on secondary data, including electronic health records and digital therapeutic vendor data. Primary outcomes were the proportion of patients reached by the prescription digital therapeutics and fidelity related to ideal use. We used qualitative methods to assess the adherence to planned activities and the barriers and facilitators to implementing prescription digital therapeutics. RESULTS: Of all 18 patients prescribed the apps, 10 (56%) downloaded the app and activated their prescription, and 8 (44%) completed at least 1 module of content. Patients who activated the app completed 1 module per week on average. Ideal use (fidelity) was defined as completing 4 modules per week and having a monthly SUD-related visit; 1 (6%) patient met these criteria for 10 weeks (of the 12-week prescription period). A total of 5 (28%) patients had prescriptions while HC was available, 2 (11%) were successfully contacted, and both declined coaching. Clinicians reported competing clinical priorities, technical challenges, and logistically complex workflows in part because the apps required a prescription. Some pilot activities were impacted by staff turnover that coincided with the COVID-19 pandemic. The facilitators to implementation were high engagement and the perception that the apps could meet patient needs. CONCLUSIONS: The pilot study encountered the barriers to implementing prescription digital therapeutics in a real-world primary care setting, especially staffing shortages, turnover, and competing priorities for clinic teams. The larger randomized trial will clarify the extent to which PF and HC improve the implementation of digital therapeutics.

Kaiser Permanente's Social Needs Network for Evaluation and Translation Empirical Research Agenda.

Introduction: Healthcare systems such as Kaiser Permanente are increasingly focusing on patients' social health. However, there is limited evidence to guide social health integration strategy. The purpose of this study was to identify social health research opportunities using a stakeholder-driven process. Methods: A modified Concept Mapping approach was implemented from June 2021 to February 2022. Stakeholders (n=746) received the prompt, "One thing I wish we knew more about to advance my work addressing social health..." An inductive content analysis approach was used to assign topics and synthesize and refine research-focused statements into research questions. Questions were then rated on impact and priority by researcher stakeholders (n=16). Mean impact and priority scores and an overall combined score were calculated. Question rankings were generated using the combined score. Results: Brainstorming produced 148 research-focused statements. A final list of 59 research questions was generated for rating. Question topics were (1) Data, Measures, and Metrics; (2) Intervention Approach and Impact; (3) Technology; (4) Role of Healthcare Systems; (5) Community-Based Organizations; (6) Equity; (7) Funding; and (8) Social Health Integration. On a scale from 1 (low) to 10 (high), the mean impact score was 6.12 (range=4.14-7.79), and the mean priority score was 5.61 (range=3.07-8.64). Twenty-four statements were rated as both high impact (>6.12) and high priority (>5.61). Conclusions: The broad range of topics with high impact and priority scores reveals how nascent the evidence base is, with fundamental research on the nature of social risk and health system involvement still needed.

Reverse Shoulder Arthroplasty Patients Younger Than 60 Years Old Exhibit Lower Clinically Significant Single Assessment Numeric Evaluation (SANE) Scores Compared to Older Patients.

INTRODUCTION: The incidence of reverse shoulder arthroplasty (RTSA) in the United States has increased. Patients under 60 years old with failed rotator cuff repairs or degenerative joint disease with glenoid deformity may be candidates for RTSA and contribute to this increase. The single assessment numeric evaluation (SANE) score is a reliable post-operative scoring technique when compared with other post-operative measures. This study aimed to compare the effect of age on the likelihood of reaching clinically significant SANE scores following RTSA. METHODS: A multicenter retrospective review was performed with a consecutive series of RTSA from December 2015 to September 2021. Patients were stratified into groups based on their age at the time of operation: (1) less than 60 years old, (2) 60-69 years old, (3) 70-79 years old, and (3) greater than 80 years old. The proportions of patients in all cohorts reaching and surpassing clinically significant thresholds at each visit were determined. Likelihood ratios were determined for each age cohort to compare the likelihood of reaching clinically significant SANE scores. RESULTS: A total of 292 of 885 (33%) patients had completed survey data over two years and were included in the study. The 70-79-year-old group was 3.152 (p=.035) times more likely to achieve minimal clinically important difference (MCID) and 2.125 (p=.048) times more likely to achieve patient-acceptable symptomatic state (PASS) compared with patients <60 years old. The cohort who was 80+ years old was also 4.867 (p=.045) times more likely to achieve MCID compared to the <60-year-old cohort. The <60 cohort had the lowest proportion of all patient cohorts achieving MCID. CONCLUSION: A lower proportion of patients younger than 60 years old undergoing RTSA achieved clinically significant post-operative SANE scores. The 70-79-year-old age group was more likely to reach MCID and PASS, and the patients who were 80+ years old were more likely to reach MCID compared to patients younger than 60 years old.

Location of distal pronator quadratus repair in distal radius fractures: A cadaveric biomechanical study.

BACKGROUND: We aimed to biomechanically evaluate the distal pronator quadratus and compare two locations of distal transection on the strength of the subsequent repair. METHODS: Eighteen fresh-frozen cadaveric specimens were dissected to the pronator quadratus muscle. Specimens were randomly allocated for transection of the pronator quadratus at the myotendinous junction (red group) or parallel to the myotendinous junction at the midsection of the distal tendinous zone (white group). For both groups, repair of the muscle was performed using two figure-of-8 sutures. The radius and ulna were positioned in 90° of wrist extension. The proximal muscular pronator quadratus was fixed in a cryo-clamp. Load-to-failure testing of the repair was performed at 1 mm/s with maximum amount of force applied to the pronator quadratus recorded for each specimen. FINDINGS: The pronator quadratus had a mean width, height, and area of 31.41 ± 5.74 mm, 53.79 ± 7.46 mm, and 1604.27 ± 429.20 mm2 respectively. The pronator quadratus distal tendinous zone had a mean width, height, and area of 29.71 ± 5.83 mm, 12.22 ± 2.79 mm, 282.94 ± 148.30 mm2 respectively. There was no significant difference between the two groups for pronator quadratus height, width, total area, or tendinous zone height, width, or total area. The average load to failure for the white group was significantly higher than that of the red group (29.46 ± 4.24 N vs. 13.78 N ± 6.66 N). INTERPRETATION: Incision and repair of the pronator quadratus in the distal tendinous region is stronger than incision and repair at the red myotendinous junction of the distal PQ.

Substantial clinical benefit values demonstrate a high degree of variability when stratified by time and geographic region.

Background: A Substantial Clinical Benefit (SCB) value is the amount of change in a patient-reported outcome measure required for a patient to feel they significantly improved from an intervention. Previously published SCB values are often cited by researchers when publishing outcomes data. Where these SCB values are set can have a large impact on the conclusions drawn from a study citing them. As such, the goal of this study was to determine the generalizability of SCB values for a procedure when stratified by time from surgery and geographic region. Methods: A nationwide outcomes database was utilized to obtain preoperative, one-year, and two-year postoperative outcome measurements for patients who underwent anatomic total shoulder arthroplasty (TSA) or reverse TSA. The data were divided into three geographic regions: the South, the Midwest, and the West. An East region was not included due to its limited number of patients. SCB values were calculated for four outcomes measures: Single Assessment Numeric Evaluation score, American Shoulder Elbow Surgeons score, Visual Analog Scale, and Western Ontario Osteoarthritis of the Shoulder score. SCB values were calculated for each region, for each procedure, and at both one and two years postoperatively. To determine the variability of potential SCBs within each region, simulated datasets were created to determine a distribution of possible calculated SCBs. Results: A total of 380 anatomic TSA patients and 543 reverse TSA patients were included for analysis. There was a high degree of variability of SCB values when stratified by procedure, time, and region. While some simulated datasets did produce homogenous SCB distributions among regions, some outcome measures demonstrated a large heterogeneity in distribution among regions, with concomitant large distributions of values within individual regions. Conclusions: There is notable heterogeneity of SCB values when stratified by region or time. The current method of citing previously published SCB values for determining the efficacy of an intervention may be inappropriate. It is likely that this variability holds true in other areas of orthopedics.

Deltotrapezial Stabilization of Acromioclavicular Joint Rotational Stability: A Biomechanical Evaluation.

Background: Despite advances in surgical management of acromioclavicular (AC) joint reconstruction, many patients fail to maintain sustained anatomic reduction postoperatively. Purpose: To determine the biomechanical support of the deltoid and trapezius on AC joint stability, focusing on the rotational stability provided by the muscles to posterior and anterior clavicular rotation. A novel technique was attempted to repair the deltoid and trapezius anatomically. Study Design: Controlled laboratory study. Methods: Twelve human cadaveric shoulders (mean ± SD age, 60.25 ± 10.25 years) underwent servohydraulic testing. Shoulders were randomly assigned to undergo serial defects to either the deltoid or trapezius surrounding the AC joint capsule, followed by a combined deltotrapezial muscle defect. Deltotrapezial defects were repaired with an all-suture anchor using an anatomic technique. The torque (N·m) required to rotate the clavicle 20° anterior and 20° posterior was recorded for the following conditions: intact (native), deltoid defect, trapezius defect, combined deltotrapezial defect, and repair. Results: When compared with the native condition, the deltoid defect decreased the torque required to rotate the clavicle 20° posteriorly by 7.1% (P = .206) and 20° anteriorly by 6.1% (P = .002); the trapezial defect decreased the amount of rotational torque posteriorly by 5.3% (P = .079) and anteriorly by 4.9% (P = .032); and the combined deltotrapezial defect decreased the amount of rotational torque posteriorly by 9.9% (P = .002) and anteriorly by 9.4% (P < .001). Anatomic deltotrapezial repair increased posterior rotational torque by 5.3% posteriorly as compared with the combined deltotrapezial defect (P = .001) but failed to increase anterior rotational torque (P > .999). The rotational torque of the repair was significantly lower than the native joint in the posterior (P = .017) and anterior (P < .001) directions. Conclusion: This study demonstrated that the deltoid and trapezius play a role in clavicular rotational stabilization. The proposed anatomic repair improved posterior rotational stability but did not improve anterior rotational stability as compared with the combined deltotrapezial defect; however, neither was restored to native stability. Clinical Relevance: Traumatic or iatrogenic damage to the deltotrapezial fascia and the inability to restore anatomic deltotrapezial attachments to the acromioclavicular joint may contribute to rotational instability. Limiting damage and improving the repair of these muscles should be a consideration during AC reconstruction.

Biomechanical Evaluation of the Efficacy of Suture Tape Augmentation for Subscapularis Peel Repair.

Background: Failure of a subscapularis repair construct after anatomic total shoulder arthroplasty can result in difficulty with internal rotation and an increased likelihood of dislocation. Although suture tape has been demonstrated to be an efficacious augment for tendonous repairs elsewhere in the body, it has not been investigated as a method for augmenting subscapularis peel repairs. Purpose: To determine the biomechanical efficacy of suture tape augmentation for the repair of a subscapularis peel. Study Design: Controlled laboratory study. Methods: Twelve human cadaveric shoulders underwent a subscapularis peel. Specimens were randomly split into 2 groups: 6 specimens underwent repair using a transosseous bone tunnel technique with 3 high-strength sutures placed with a Mason-Allen configuration (control group), and 6 specimens underwent the control repair using augmentation with 2 suture tapes placed in an inverted mattress fashion and secured to the proximal humerus using a suture anchor (augmentation group). Shoulders underwent biomechanical testing to compare repair displacement with cyclic loading, load at ultimate failure, and construct stiffness. Results: There were no significant between-group differences in displacement after cyclic loading at the superior (P = .87), middle (P = .47), or inferior (P = .77) portions of the subscapularis tendon. Load to failure was significantly greater in the augmentation group (585.1 ± 97.4 N) than in the control group (358.5 ± 81.8 N) (P = .001). Stiffness was also greater in the augmentation group (71.8 ± 13.7 N/mm) when compared with the control group (48.7 ± 5.7 N/mm) (P = .003). Conclusion: Subscapularis peel repair with augmentation via 2 inverted mattress suture tapes secured with an anchor in the proximal humerus conferred significantly greater load at ultimate failure and construct stiffness when compared with a traditional repair using 3 Mason-Allen sutures. There was no difference in repair displacement with cyclic loading between the repair groups. Clinical Relevance: Suture tape augmentation of subscapularis peel repairs after shoulder arthroplasty provides an effective segment to the strength of the repair.

Biomechanical Efficacy of Tape Cerclage as an Augment or Stand-alone for Coracoclavicular Ligament Reconstruction.

BACKGROUND: Loss of initial reduction of the acromioclavicular joint after coracoclavicular (CC) ligament reconstruction remains a challenge for various repair techniques. Previous studies using polydioxanone suture cerclage augments for CC ligament reconstruction demonstrated poor clinical and biomechanical outcomes. Tape-style sutures have recently gained popularity because of their added stiffness and strength relative to traditional sutures. These tape cerclage systems have yet to be biomechanically studied in CC ligament reconstruction. PURPOSE: To determine the efficacy of a tape cerclage system as an augment to CC ligament reconstruction. STUDY DESIGN: Controlled laboratory study. METHODS: A total of 24 human cadaveric shoulders were utilized. These were divided into 4 repair groups: anatomic CC ligament reconstruction (ACCR), ACCR with a tape cerclage augment (ACCR + C), tendon graft sling with a cerclage augment (TGS + C), or tape cerclage sling alone (CS). The repairs underwent superior/inferior cyclic loading to evaluate for displacement. Specimens were visually inspected for cortical erosion by the tape cerclage after cyclic loading. Finally, the constructs underwent superior plane load-to-failure testing. RESULTS: Less displacement after cyclic loading was observed in the ACCR + C (mean ± SD, 0.42 ± 0.32 mm), TGS + C (0.92 ± 0.42 mm), and CS (0.93 ± 0.39 mm) groups as compared with the ACCR group (4.42 ± 3.40 mm; P = .002). ACCR + C (813.3 ± 257.5 N), TGS + C (558.0 ± 120.7 N), and CS (759.5 ± 173.7 N) demonstrated significantly greater load at failure relative to ACCR (329.2 ± 118.2 N) (P < .001). ACCR + C (60.88 ± 17.3 N/mm), TGS + C (44.97 ± 9.15 N/mm), and CS (54.52 ± 14.24 N/mm) conferred greater stiffness than ACCR (27.43 ± 6.94 N/mm) (P = .001). No cortical erosion was demonstrated in any specimen after cyclic loading. CONCLUSION: In a cadaveric model at time zero, repairs utilizing a tape cerclage system confer significantly greater load to failure and stiffness, as well as decreased displacement with cyclic loading, when compared with traditional ACCR repair. CLINICAL RELEVANCE: Tape cerclage augmentation may provide a useful augment for CC ligament reconstruction.

Study protocol for a factorial-randomized controlled trial evaluating the implementation, costs, effectiveness, and sustainment of digital therapeutics for substance use disorder in primary care (DIGITS Trial).

BACKGROUND: Experts recommend that treatment for substance use disorder (SUD) be integrated into primary care. The Digital Therapeutics for Opioids and Other SUD (DIGITS) Trial tests strategies for implementing reSET® and reSET-O®, which are prescription digital therapeutics for SUD and opioid use disorder, respectively, that include the community reinforcement approach, contingency management, and fluency training to reinforce concept mastery. This purpose of this trial is to test whether two implementation strategies improve implementation success (Aim 1) and achieve better population-level cost effectiveness (Aim 2) over a standard implementation approach. METHODS/DESIGN: The DIGITS Trial is a hybrid type III cluster-randomized trial. It examines outcomes of implementation strategies, rather than studying clinical outcomes of a digital therapeutic. It includes 22 primary care clinics from a healthcare system in Washington State and patients with unhealthy substance use who visit clinics during an active implementation period (up to one year). Primary care clinics implemented reSET and reSET-O using a multifaceted implementation strategy previously used by clinical leaders to roll-out smartphone apps ("standard implementation" including discrete strategies such as clinician training, electronic health record tools). Clinics were randomized as 21 sites in a 2x2 factorial design to receive up to two added implementation strategies: (1) practice facilitation, and/or (2) health coaching. Outcome data are derived from electronic health records and logs of digital therapeutic usage. Aim 1's primary outcomes include reach of the digital therapeutics to patients and fidelity of patients' use of the digital therapeutics to clinical recommendations. Substance use and engagement in SUD care are additional outcomes. In Aim 2, population-level cost effectiveness analysis will inform the economic benefit of the implementation strategies compared to standard implementation. Implementation is monitored using formative evaluation, and sustainment will be studied for up to one year using qualitative and quantitative research methods. DISCUSSION: The DIGITS Trial uses an experimental design to test whether implementation strategies increase and improve the delivery of digital therapeutics for SUDs when embedded in a large healthcare system. It will provide data on the potential benefits and cost-effectiveness of alternative implementation strategies.

Glenohumeral Arthrodesis for Treatment of Unique Instability with Axillary Nerve Injury: A Case Report.

Introduction: Traumatic shoulder dislocations in elderly patients can result in significant shoulder pathology. Rotator cuff tears and recurrent instability are common complications follow a dislocation event, while axillary nerve injury is less common. While there have been rare cases of recurrent shoulder instability with concomitant axillary nerve injury, there have been no prior cases, in which concurrent fracture fragmentation resulted in the initial gross instability. Case Report: A 68-year-old male with painful gross instability presents following a traumatic dislocation. The patient sustained an axillary nerve injury to the ipsilateral side resulting in a non-functioning deltoid. Pre-operative X-rays showed recurrent chronic glenohumeral dislocation, computerized tomography imaging showed a greater tuberosity fracture, and magnetic resonance imaging showed a massive cuff tear with retraction and atrophy. Given the level of instability and deltoid dysfunction, the patient was treated with shoulder arthrodesis. Intraoperatively, a large fragment of greater tuberosity with ligamentous attachments was found adhered to the anterior glenoid. After arthrodesis, the patient's pain and function improved significantly. Conclusion: When treating elderly patients with gross instability following a traumatic dislocation, surgeons should keep in mind the high likelihood of concomitant avulsion fracture, and that migratory cortical fragments can be a nidus for a patient's instability. When selected for appropriately, these patients can be effectively treated with shoulder arthrodesis with excellent improvements of pain and functionality.

Optimization of tissue adhesive curing time for surgical wound closure.

AIMS: Tissue adhesives (TAs) are a commonly used adjunct to traditional surgical wound closures. However, TAs must be allowed to dry before application of a surgical dressing, increasing operating time and reducing intraoperative efficiency. The goal of this study is to identify a practical method for decreasing the curing time for TAs. METHODS: Six techniques were tested to determine which one resulted in the quickest drying time for 2-octyle cyanoacrylate (Dermabond) skin adhesive. These were nothing (control), fanning with a hand (Fanning), covering with a hand (Covering), bringing operating room lights close (OR Lights), ultraviolet lights (UV Light), or prewarming the TA applicator in a hot water bath (Hot Water Bath). Equal amounts of TA were applied to a reproducible plexiglass surface and allowed to dry while undergoing one of the six techniques. The time to complete dryness was recorded for ten specimens for each of the six techniques. RESULTS: Use of the Covering, OR Lights, and Hot Water Bath techniques were associated with a 25- (p = 0.042), 27- (p = 0.023), and 30-second (p = 0.009) reduction in drying time, respectively, when compared to controls. The UV Light (p = 0.404) and Fanning (p = 1.000) methods had no effect on drying time. CONCLUSION: Use of the Covering, OR Lights, and Hot Water Bath techniques present a means for reducing overall operating time for surgeons using TA for closure augmentation, which can increase intraoperative efficiency. Further studies are needed to validate this in vivo.Cite this article: Bone Jt Open 2022;3(8):607-610.

Inpatient versus outpatient shoulder arthroplasty outcomes: A propensity score matched risk-adjusted analysis demonstrates the safety of outpatient shoulder arthroplasty.

OBJECTIVES: Beginning January 1, 2021 total shoulder arthroplasty (TSA) was removed from the Medicare (U.S national healthcare for patients ≥ 65years of age) inpatient-only list. Furthermore, there is limited data comparing outpatient and inpatient TSA among recent contemporary large population databases. This study aimed to analyze shoulder arthroplasty outcomes between inpatient and outpatient procedures at the national level. METHODS: The American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database was utilized (2015-2019). Cases with a current procedural terminology of 23472 indicative of primary TSA and reverse total shoulder arthroplasty were included (N = 22,452). Outcomes were then analyzed in two approaches: unmatched analysis and propensity score matched risk-adjusted analysis. RESULTS: Overall, 9.7% (N = 2,185) of cases were performed outpatient and 90.3% (N = 20,357) of cases were performed inpatient. The rate of outpatient procedures has been steadily increasing (2015: 8.3%, 2016: 14.7%, 2017: 15.8%, 2018: 26.5%, 2019: 34.6%; P < 0.001). Outpatients were more likely to be male (50.7% vs. 43.7%) and younger (age < 65; 37.0% vs. 27.9%) and less likely to be ASA class 3 or 4 (49.5% vs. 58.3%). Outpatients had fewer comorbidities including obesity (46.1% vs. 51.9%), hypertension (60.5% vs. 67.4%), diabetes (15.1 vs. 18.2%), chronic obstructive pulmonary disease (4.8% vs. 7.0%), bleeding disorders (1.3% vs. 2.5%), or chronic steroid use (3.5% vs. 5.0%; all P < 0.001). In a non-risk matched analysis of outcomes, outpatient procedures displayed lower rates of any adverse event (3.5% vs. 5.3%; P < 0.001), minor adverse events (1.5% vs. 3.0%; P = 0.001), and readmission (2.2% vs. 2.8%; P = 0.025). Following a propensity score matched analysis, two risk matched cohorts of outpatient (N = 2,172) and inpatient (N = 2,172) procedures were identified. Subsequent analysis of outcomes revealed no significant differences in outcome metrics between risk-matched outpatient and inpatient procedures. CONCLUSIONS: From 2015 to 2019, there has been a four-fold increase in the proportion of outpatient shoulder arthroplasty cases in the ACS-NSQIP database. This study shows that outpatient shoulder arthroplasty may be safely performed in a select cohort of patients without increased risk of adverse events. After adjusting for comorbidities, there were no differences in clinical outcomes or rates of adverse outcomes between inpatient and outpatient shoulder arthroplasty. LEVEL OF EVIDENCE: Retrospective Observational Study, Level IV.

Effect of new Medicare enrollment on health, healthcare utilization, and cost: A scoping review.

BACKGROUND: More than three million Americans turn 65 each year and newly enroll in Medicare, making this one of the most common insurance transitions. Non-Medicare insurance transitions are associated with changes in health, healthcare utilization and costs. In addition, older Americans have higher morbidity, mortality, healthcare utilization, and healthcare costs than the general population. However, the effect of new Medicare enrollment on these outcomes is unclear. DESIGN: We conducted a scoping review to rigorously identify the scope of evidence on the association between new Medicare enrollment and health, healthcare utilization and costs. SETTING: We included English-language, peer-reviewed, studies cataloged in Medline (PubMed) and EconLit from 1998 to 2018. PARTICIPANTS: Individuals newly enrolling in Medicare. MEASUREMENTS: We measured health (e.g., self-reported health), healthcare utilization (e.g., provider visits, preventive care, and hospitalizations) and costs (e.g., patient out-of-pocket and health plan spending). RESULTS: We screened 5265 articles and included 20 articles. New Medicare enrollment was found to increase self-reported health and healthcare utilization overall, as well as reduce disparities across racial and socioeconomic strata. Provider visits, preventive care and hospitalizations all increased. However, patient out-of-pocket spending decreased, and health plan spending also decreased, when Medicare's lower prices were accounted for. Few studies compared outcomes among new Medicare Advantage enrollees with new Medicare fee-for-service enrollees. None of the studies specifically evaluated the effect of new Medicare enrollment on adults with multiple chronic conditions. CONCLUSION: New Medicare enrollment improves access overall and reduces access disparities. However, the impact of new Medicare enrollment among subgroups defined by insurance coverage type and number of chronic conditions is less clear. Future work should also evaluate the mechanism for increases in hospitalizations.

A systematic review of measures of implementation players and processes: Summarizing the dearth of psychometric evidence.

Background: Measurement is a critical component for any field. Systematic reviews are a way to locate measures and uncover gaps in current measurement practices. The present study identified measures used in behavioral health settings that assessed all constructs within the Process domain and two constructs from the Inner setting domain as defined by the Consolidated Framework for Implementation Research (CFIR). While previous conceptual work has established the importance social networks and key stakeholders play throughout the implementation process, measurement studies have not focused on investigating the quality of how these activities are being carried out. Methods: The review occurred in three phases: Phase I, data collection included (1) search string generation, (2) title and abstract screening, (3) full text review, (4) mapping to CFIR-constructs, and (5) "cited-by" searches. Phase II, data extraction, consisted of coding information relevant to the nine psychometric properties included in the Psychometric And Pragmatic Rating Scale (PAPERS). In Phase III, data analysis was completed. Results: Measures were identified in only seven constructs: Structural characteristics (n = 13), Networks and communication (n = 29), Engaging (n = 1), Opinion leaders (n = 5), Champions (n = 5), Planning (n = 5), and Reflecting and evaluating (n = 5). No quantitative assessment measures of Formally appointed implementation leaders, External change agents, or Executing were identified. Internal consistency and norms were reported on most often, whereas no studies reported on discriminant validity or responsiveness. Not one measure in the sample reported all nine psychometric properties evaluated by the PAPERS. Scores in the identified sample of measures ranged from "-2" to "10" out of a total of "36." Conclusions: Overall measures demonstrated minimal to adequate evidence and available psychometric information was limited. The majority were study specific, limiting their generalizability. Future work should focus on more rigorous measure development and testing of currently existing measures, while moving away from creating new, single use measures. Plain Language Summary: How we measure the processes and players involved for implementing evidence-based interventions is crucial to understanding what factors are helping or hurting the intervention's use in practice and how to take the intervention to scale. Unfortunately, measures of these factors-stakeholders, their networks and communication, and their implementation activities-have received little attention. This study sought to identify and evaluate the quality of these types of measures. Our review focused on collecting measures used for identifying influential staff members, known as opinion leaders and champions, and investigating how they plan, execute, engage, and evaluate the hard work of implementation. Upon identifying these measures, we collected all published information about their uses to evaluate the quality of their evidence with respect to their ability to produce consistent results across items within each use (i.e., reliable) and if they assess what they are intending to measure (i.e., valid). Our searches located over 40 measures deployed in behavioral health settings for evaluation. We observed a dearth of evidence for reliability and validity and when evidence existed the quality was low. These findings tell us that more measurement work is needed to better understand how to optimize players and processes for the purposes of successful implementation.

Measuring characteristics of individuals: An updated systematic review of instruments' psychometric properties.

Background: Identification of psychometrically strong implementation measures could (1) advance researchers' understanding of how individual characteristics impact implementation processes and outcomes, and (2) promote the success of real-world implementation efforts. The current study advances the work that our team published in 2015 by providing an updated and enhanced systematic review that identifies and evaluates the psychometric properties of implementation measures that assess individual characteristics. Methods: A full description of our systematic review methodology, which included three phases, is described in a previously published protocol paper. Phase I focused on data collection and involved search string generation, title and abstract screening, full-text review, construct assignment, and measure forward searches. During Phase II, we completed data extraction (i.e., coding psychometric information). Phase III involved data analysis, where two trained specialists independently rated each measurement tool using our psychometric rating criteria. Results: Our team identified 124 measures of individual characteristics used in mental or behavioral health research, and 123 of those measures were deemed suitable for rating using Psychometric and Pragmatic Evidence Rating Scale. We identified measures of knowledge and beliefs about the intervention (n = 76), self-efficacy (n = 24), individual stage of change (n = 2), individual identification with organization (n = 7), and other personal attributes (n = 15). While psychometric information was unavailable and/or unreported for many measures, information about internal consistency and norms were the most commonly identified psychometric data across all individual characteristics' constructs. Ratings for all psychometric properties predominantly ranged from "poor" to "good." Conclusion: The majority of research that develops, uses, or examines implementation measures that evaluate individual characteristics does not include the psychometric properties of those measures. The development and use of psychometric reporting standards could advance the use of valid and reliable tools within implementation research and practice, thereby enhancing the successful implementation and sustainment of evidence-based practice in community care. Plain Language Summary: Measurement is the foundation for advancing practice in health care and other industries. In the field of implementation science, the state of measurement is only recently being targeted as an area for improvement, given that high-quality measures need to be identified and utilized in implementation work to avoid developing another research to practice gap. For the current study, we utilized the Consolidated Framework for Implementation Research to identify measures related to individual characteristics' constructs, such as knowledge and beliefs about the intervention, self-efficacy, individual identification with the organization, individual stage of change, and other personal attributes. Our review showed that many measures exist for certain constructs (e.g., measures related to assessing providers' attitudes and perceptions about evidence-based practice interventions), while others have very few (e.g., an individual's stage of change). Also, we rated measures for their psychometric strength utilizing an anchored rating system and found that most measures assessing individual characteristics are in need of more research to establish their evidence of quality. It was also clear from our results that frequency of use/citations does not equate to high quality, psychometric strength. Ultimately, the state of the literature has demonstrated that assessing individual characteristics of implementation stakeholders is an area of strong interest in implementation work. It will be important for future research to focus on clearly delineating the psychometric properties of existing measures for saturated constructs, while for the others the emphasis should be on developing new, high-quality measures and make these available to stakeholders.
