Self-efficacy, motivation, social support, and alliance as predictors of youth psychotherapy outcomes in usual care.

OBJECTIVE: We examined how youth self-efficacy, motivation for treatment, social support, and therapeutic alliance relate to psychotherapy outcomes of patients receiving services at outpatient community clinics. We hypothesized that (1) these variables would increase throughout the course of therapy, (2) baseline scores would predict initial ratings of distress, (3) baseline scores would predict the rate of change in symptoms throughout treatment, and (4) changes in these variables would be associated with symptom change over the course of treatment. METHOD: Participants included 150 adolescents at community outpatient treatment centers. Data was collected prior to beginning treatment, and every three weeks afterward until termination. We used hierarchical linear modeling (HLM) to address our hypotheses. RESULTS: We found that (1) youth ratings of self-efficacy, social support, and motivation increased throughout treatment, (2) initial self-efficacy and social support were associated with initial levels of distress, (3) ratings of youth self-efficacy at intake predicted its rate of change over therapy, and (4) changes in all variables during therapy were related to lower distress at termination. DISCUSSION: Results suggest that these variables may affect the trajectory and course of treatment in community-based treatment settings. These results may have implications for treatment planning to maximize treatment effectiveness.

Are Patients Being Appropriately Selected for Same-Day Discharge Total Knee Arthroplasty?

BACKGROUND: Decreased cost associated with same-day discharge (SDD) total knee arthroplasty (TKA) has led to an increased interest in this topic. The purpose of this study is to investigate whether there is a population of TKA patients in which SDD has similar rates of 30-day complications compared to patients discharged on postoperative day 1 or 2. METHODS: Using the American College of Surgeons National Surgical Quality Improvement Program database from 2012 to 2018, 6,327 TKA patients who had a SDD (length of stay [LOS] = 0) were matched to TKA patients who had an LOS of 1 or 2 days. All SDD patients were successfully matched 1:1 using the morbidity probability variable (a composite variable of demographics, comorbidities, and laboratory values). Patients were divided into quartiles based on their morbidity probability. Bivariate logistic regressions were then used to compare any complication and major complication rates in the SDD quartiles to the corresponding quartiles with an LOS of 1 or 2 days. RESULTS: When comparing the 1st quartiles (healthiest), there was no difference between the cohorts in any complication (odds ratio [OR] = 0.960, 95% CI 0.552-1.670, P = .866) and major complications (OR = 0.999, 95% CI = 0.448-2.231, P = .999). The same was observed in quartile 2 (any complications: OR = 1.161, 95% CI = 0.720-1.874, P = .540). Comparing the third quartiles, there was an increase in all complications with SDD (OR = 1.784, 95% CI = 1.125-2.829, P = .014), but no difference in major complications (OR = 1.635, 95% CI = 0.874-3.061, P = .124). Comparing the fourth quartiles (least healthy), there was an increase in all complications (OR = 1.384, 95% CI = 1.013-1.892, P = .042) and major complications (OR = 1.711, 95% CI = 1.048-2.793, P = .032) with SDD. CONCLUSION: The unhealthiest 50% of patients in this study who underwent SDD TKA were at an increased risk of having any complication, calling into question the current state of patient selection for SDD TKA.

Blood management in total hip arthroplasty: a nationwide trend analysis from 2011 to 2018.

PURPOSE: With the advent of practice changes surrounding preoperative patient optimization and postoperative protocols, a marked reduction has been reported in blood transfusion rates following total hip arthroplasty (THA). Thus, the purpose of this study was to examine differences in the prevalence of preoperative anemia, thrombocytopenia, elevated international normalized ratio (INR), bleeding disorders, and pre- and postoperative blood transfusions over the last decade. METHODS: From 2011 to 2018, the American College of Surgeons National Quality Improvement Program database was queried for all primary THA procedures (n = 208,796). The following continuous variables were examined using analysis of variance: preoperative hematocrit (HCT), platelet count, and INR. The following categorical variables were analyzed by chi-squared tests: anemia (HCT < 35.5% for females and < 38.5% for males), thrombocytopenia (platelet count < 150,000/µL), INR > 2.0, bleeding disorders, preoperative transfusions, and postoperative transfusions. RESULTS: There were decreases in preoperative anemia (2011: 16.2%; 2018: 11.4%, p < 0.001) and postoperative transfusions (2011: high = 22.2%; 2018: low = 1.3%, p < 0.001). Statistically significant but clinically irrelevant changes were observed in preoperative HCT (2011: low = 40.3, 2018: high = 41.1, p < 0.001), platelet count (2011: low = 248,700; 2018: high = 250,100, p < 0.001), thrombocytopenia (2011: high = 4.9%; 2018: low = 4.3%, p = 0.036), INR > 2.0 (2011: high = 1.1%; 2018: low = 0.7%, p = 0.001), bleeding disorders (2011: high = 2.9%; 2018: low = 2.0%, p < 0.001), and preoperative transfusions (2011: high = 0.2%; 2018: low = 0.1%, p = 0.007). CONCLUSION: Large decreases in the number of patients with preoperative anemia and those receiving postoperative blood transfusion were observed during the study period. Future investigation is needed to ascertain whether this is due to patient optimization, practice changes, "cherry-picking" of healthy patients, or a combination of these factors.

Calprotectin Lateral Flow Test: Consistent Across Criteria for Ruling Out Periprosthetic Joint Infection.

BACKGROUND: There are multiple sets of criteria used to define periprosthetic joint infection. The objective of this study is to compare the diagnostic accuracy of the calprotectin lateral flow point-of-care (POC) test in total knee arthroplasty (TKA) patients to diagnose infection using 3 different sets of criteria: (1) 2013 Musculoskeletal Infection Society, (2) 2018 Intentional Consensus Meeting (ICM), and (3) the 2019 proposed European Bone and Joint Infection Society criteria as reference standards. METHODS: From October 2018 to January 2020, 123 intraoperative synovial fluid samples were prospectively collected from revision total knee arthroplasty patients and tested using a calprotectin lateral flow POC assay. Data were reviewed and adjudicated by 2 independent reviewers blinded to calprotectin test results. RESULTS: The 3 criteria sets had 91.8% agreement. Using 2013 Musculoskeletal Infection Society criteria, the POC test demonstrated a sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under the curve (AUC) of 98.1%, 95.7%, 94.5%, 98.5%, and 0.969, respectively. Using the 2018 ICM, the POC test demonstrated a sensitivity, specificity, PPV, NPV, and AUC of 98.2%, 98.5%, 98.2%, 98.5%, and 0.984, respectively. Using the 2019 proposed European Bone and Joint Infection Society criteria, the POC test demonstrated a sensitivity, specificity, PPV, NPV, and AUC of 93.2%, 100.0%, 100.0%, 94.2%, and 0.966, respectively. CONCLUSION: The calprotectin lateral flow POC test had excellent sensitivity and specificity across current available periprosthetic joint infection definitions, with the best performance observed when applying 2018 ICM criteria.

Addressing Adolescent Stress in School: Perceptions of a High School Wellness Center.

Adolescents are often burdened with academic, home, and peer stressors. With adolescent mental health issues and suicide on the rise, administrators have worked with nonprofit organizations and the community to address stress and internalized behavior problems. School-based wellness centers are tranquil rooms with various sensory activities, calming nature scenes, and sounds for relaxation purposes. School-based wellness centers may have behavioral effects by reducing exposure to aversive events and increasing access to positive and negative reinforcers. There has not yet been a formal study of school-based wellness centers published in the literature. In the present study, we used questionnaires to examine the perceptions of 752 students, 124 parents, and 69 school staff of their high school wellness center. Results indicated that stakeholders had positive perceptions of the wellness center. In particular, results implied that stakeholders believed the wellness center contributed to students' academic success, elevation of mood, confidence, and coping skills. Results also suggested that attendance at the wellness center was associated with a decrease in student stress and anxiety, though recommendations for improvements were noted. Implications and limitations of this study are discussed. Supplementary Information: The online version contains supplementary material available at 10.1007/s43494-022-00079-1.

Demographic, comorbidity, and episode of care trends in unicompartmental knee arthroplasty: 2008 to 2018.

PURPOSE: The purpose of this study is to assess how unicompartmental knee arthroplasty (UKA) patient demographics, comorbidities, and episode of care outcomes have changed from 2008 to 2018 in order to better understand the impact of recent changes in healthcare ideology on UKA. METHODS: The National Surgical Quality Improvement Program was queried to identify demographics, comorbidities, and episode of care outcomes in patients undergoing primary UKA from 2008 to 2013 (n = 3096) vs 2014-2018 (n = 9073). Trends were analyzed using Student's t-tests for continuous variables and Chi-squared tests and Fisher's exact tests for categorical variables. RESULTS: When comparing the years 2008-2013 to 2014-2018, there was no clinically significant difference in age, body mass index (BMI), proportion of patients with a BMI > 40 kg/m2, percentage of diabetes (15.0% vs 15.5; p = 0.715), smoking status (10.2% vs 9.4%; 0.177), COPD (3.0% vs 2.8%; p = 0.645), CHF within 30 days (< 0.1% vs 0.2%; p = 0.060), or acute renal failure (0.0% vs < 0.1%; p = 0.621) in patients undergoing UKA. However, the rate of patients with dyspnea, (5.7% versus 3.6%; p < 0.001), anemia (9.4 versus 7.3%; p < 0.001), and overall morbidity/mortality probability have improved, with a decrease in hospital LOS (2.2 ± 1.9 days versus 1.4 ± 2.1 days; p < 0.001) and an increase in home-discharge (90.7% versus 95.2%; p < 0.001). CONCLUSION: From 2008 to 2018, there was minimal improvement in UKA patients' modifiable comorbidities. However, despite the lack of significant change in patient health status, our findings showed improvement in episode-of-care outcomes, implying that the value of UKA has been increasing over the last decade.

The Potential Effects of Imposing a Body Mass Index Threshold on Patient-Reported Outcomes After Total Knee Arthroplasty.

BACKGROUND: Operative eligibility thresholds based on body mass index (BMI) alone may risk restricting access to improved pain control, function, and quality of life. This study evaluated the use of BMI-cutoffs to offering TKA in avoiding: 1) 90-day readmission, 2) one-year mortality, and 3) failure to achieve clinically important one-year PROMS improvement (MCID). METHODS: A total of 4126 primary elective unilateral TKA patients from 2015 to 2018 were prospectively collected. For specific BMI(kg/m2) cutoffs: 30, 35, 40, 45, and 50, the positive predictive value (PPV) for 90-day readmission, one-year mortality, and failure to achieve one-year MCID were calculated. The number of patients denied complication-free postoperative courses per averted adverse outcome/failed improvement was estimated. RESULTS: Rates of 90-day readmission and one-year mortality were similar across BMI categories (P > .05, each). PPVs for preventing 90-day readmission and one-year mortality were low across all models of BMI cutoffs. The highest PPV for 90-day readmission and one-year mortality was detected at cutoffs of 45 (6.4%) and 40 (0.87%), respectively. BMI cutoff of 40 would deny 18 patients 90-day readmission-free, and 194 patients one-year mortality-free postoperative courses for each averted 90-day readmission/one-year mortality. Such cutoff would also deny 11 patients an MCID per avoided failure. Implementing BMI thresholds alone did not influence the rate of improvements in KOOS-PS, KRQOL, or VR-12. CONCLUSION: Utilizing BMI cutoffs as the sole determinants of TKA ineligibility may deny patients complication-free postoperative courses and clinically important improvements. Shared decision-making supported by predictive tools may aid in balancing the potential benefit TKA offers to obese patients with the potentially increased complication risk and cost of care provision.

Parent functioning and child psychotherapy outcomes: Predicting outcomes in usual care.

OBJECTIVE: The purpose of this study was (1) to examine whether three domains of a parent's functioning-parent distress, interpersonal relationships, and social role performance-changed over the course of their child's treatment, (2) to examine how these factors as measured at intake predicted youth progress in psychotherapy, and (3) to examine whether changes in these parent factors over the course of youth psychotherapy were associated with changes in youth symptoms. METHOD: Participants were 339 youth, ages 4-17 and their parents from a community outpatient treatment setting undergoing usual care. Parent and child outcomes were examined across five time points over the course of child treatment. Hierarchical linear modeling was used to examine the relationship between parent domains and youth progress in therapy. RESULTS: Results suggested that parent domains significantly predicted their child's symptoms at intake as well as change in psychotherapy. In addition, parent domains improved over the course of youth treatment and the progression of these changes was related to the progression of changes in youth scores across the course of treatment. CONCLUSIONS: The results of this study highlight the important relationship between youth and parent functioning in the context of treatment of youth mental health issues.

Effects of Estimated Glomerular Filtration Rate on 30-Day Mortality and Postoperative Complications After Total Hip Arthroplasty: A Risk Stratification Instrument.

BACKGROUND: Chronic kidney disease (CKD) is a relatively common comorbidity that has been shown to adversely affect outcomes in total hip arthroplasty (THA), as well as to increase the procedure's total costs. However, the effect of different stages of kidney disease and the association of estimated glomerular filtration rate (eGFR) with perioperative THA complications are less understood. Therefore, the aims of this study were to investigate the relationships between eGFR, both as a categorical and continuous variable and 30-day outcomes and complications. METHODS: The National Surgical Quality Improvement Program database was used to identify 101,925 primary THAs between January 1, 2008, and December 31, 2016. The following outcomes were assessed: 30-day mortality, 30-day major complications, 30-day minor complications, specific complications, and discharge disposition. To evaluate the effect of eGFR status on outcomes and complication, multivariate regression models were created to adjust for differences in patient demographics and comorbidities. In addition, multivariate spline regressions were developed to assess the nonlinear relationships between eGFR as a continuous variable and the outcomes of interest. RESULTS: Our study revealed that as eGFR decreases to <30 mL/min/1.73 m2, there is an increased risk for mortality and nonhome discharge (P < .05). There was an increased risk for any major complication and any minor complication as well as several specific medical complications such as transfusion and myocardial infarction (P < .05) for an eGFR of <60 mL/min/1.73 m2. Patients' eGFR had a nonlinear relationship with mortality (P = .0001), any major complication (P < .001), and any minor complication (P < .001), as well as a number of other specific medical complications. Once the eGFR, <60 mL/min/1.73 m2 the increase was exponential for mortality, major complications, and minor complications. For example, mortality increased of 900% for <15 mL/min/1.73 m2 or on dialysis, 600% for 15 to 30 mL/min/1.73 m2 and 50% for 30 to 60 mL/min/1.73 m2. Similarly, nonlinear relationships were discovered between eGFR and nonhome discharge (P < .001). CONCLUSION: Patients with lower eGFR, and in particular those with <30 mL/min/1.73 m2, are more likely to sustain medical complications and have 6 to 9 times higher mortality than patients with normal eGFR. THA patients with CKD should be appropriately counseled and advised on the risk of postoperative complications by using eGFR as a screening tool.

Have Venous Thromboembolism Rates Decreased in Total Hip and Knee Arthroplasty?

BACKGROUND: Venous thromboembolism (VTE) is a major cause of morbidity, mortality, and healthcare costs in arthroplasty patients. In an effort to reduce VTEs, numerous strategies and guidelines have been implemented, but their impact remains unclear. The purpose of this study is to compare annual trends in 30-day VTE, deep vein thrombosis (DVT), pulmonary embolism (PE), and all-cause mortality in (1) total hip arthroplasty (THA) and (2) total knee arthroplasty (TKA). METHODS: The American College of Surgeons National Surgical Quality Improvement Program (NSQIP) database identified 363,530 patients who received a TKA or THA from 2008 to 2016. Bivariate analysis was performed to assess the association between the year in which surgery was performed and demographics and comorbidities. Bimodal multivariate logistic regression models for THA and TKA were developed for 2009-2016 using 2008 as a reference. RESULTS: Overall incidence of VTE, DVT, PE, and mortality for THA were 0.6%, 0.4%, 0.3%, and 0.2%, respectively. Based off of multivariate regression VTE, DVT, PE, and mortality rates have shown no significant (P > .05) change from 2008 to 2016 in THA patients. Overall incidence of VTE, DVT, PE, and mortality for TKA were 1.4%, 0.9%, 0.6%, and 0.1%, respectively. Multivariate regression revealed reductions when compared to 2008 for VTEs and DVTs from 2009 to 2016 (P < .05) for TKA patients. A significant reduction in PEs (P = .002) was discovered for 2016, while no significant change was observed in mortality (P > .05). CONCLUSION: Approximately 1 in 71 patient undergoing TKA, and 1 in 167 undergoing THA developed a VTE within 30 days after surgery. Our study demonstrated that VTE incidence rates have decreased in TKA, while remaining stable in THA over the past 8 years. Further research to determine the optimal prophylaxis algorithm that would allow for a personalized, efficacious, and safe thromboprophylaxis regimen is needed. LEVEL OF EVIDENCE: III.

Estimated Glomerular Filtration Rate as a Risk Stratification Tool for Early Complications in Revision Total Hip and Knee Arthroplasty.

BACKGROUND: Establishing an association between postoperative outcomes and the spectrum of renal function would allow for more informed decisions to manage surgical risks and improved patient-specific care. Estimated glomerular filtration rate (eGFR) can be calculated from standard prescreening measurements to gauge renal function. This work investigates the effect of eGFR, as a continuous and categorical variable, on mortality and major and minor complications in patients undergoing revision total knee and hip arthroplasty. METHODS: 25,056 patients having undergone revision total hip and knee arthroplasty from 2013 to 2016 were identified using the National Quality Improvement Program database. The investigated outcomes included 30-day mortality, major complications, and minor complications. Multivariate regression models were created to evaluate the effect of eGFR on the outcomes of interest. Multivariate spline regressions were generated to assess for nonlinear relationships between eGFR as a continuous variable and the outcomes. RESULTS: Our study revealed that as eGFR decreased <60 mL/min/1.73 m2, mortality (P = .0001), any major complication (P < .001), and any minor complication (P < .001) increased. Patients with eGFR 15-30 mL/min/1.73 m2 had increased risk for mortality (P = .033). There was an increased risk for any major complication at an eGFR 30-60 and <15 mL/min/1.73 m2, (P < .05). There was an increased risk of minor complications for those with hyperfiltration and <60 mL/min/1.73 m2. CONCLUSION: Patients with lower preoperative eGFR generally display an increased risk for complications after revision total hip and knee arthroplasty. Proper consideration should be given to this patient population before surgical intervention to allow for preventative measures to be taken to improve patient outcomes.

Perioperative Outcomes and Complications After Primary Total Hip Arthroplasty in Patients With Disproportionately Short Stature: A Matched Cohort Analysis.

BACKGROUND: This study compared (1) perioperative outcomes, (2) postoperative complications, and (3) reoperation rates after primary total hip arthroplasty (THA) between short stature patients and matched control patients. METHODS: A review of primary THA patients from 2012 to 2017 using an institutional database was conducted. This yielded 12,850 patients of which 108 were shorter than 148 cm. These patients were matched 1:1 by age (P = .527), gender (P = .664), and body mass index (P = .240) to controls. The final study population with minimum 1-year follow-up that was included for analysis comprised 47 patients in the short stature cohort and 57 patients in the control cohort. The following outcomes/complications were compared: operative times, lengths of stay (LOSs), intraoperative fractures, minor complications, 90-day readmissions, and revisions. RESULTS: Operative times were significantly longer in the short stature cohort than in the matched control cohort (133 ± 65 minutes vs 104 ± 30 minutes, P = .005). In addition, hospital LOS was slightly longer in the short stature group than in the matched control groups (3.2 ± 1.5 days vs 2.6 ± 1.0, P = .017). Rates of intraoperative fractures (P = 1.000), minor complications P = .406), 90-day readmissions (P = .5000), and revision (P = .202) were similar between the short stature and control cohorts. CONCLUSION: Patients with disproportionately short stature had longer operative times and slight longer LOS. However, complication and readmission rates were similar. Future studies with larger sample sizes are warranted to confirm these findings and further evaluate implant survivorship in this unique THA patient population.

Publication integrity in orthopaedic journals: the self-citation in orthopaedic research (SCOR) threshold.

BACKGROUND: The impact factor (IF) is the most commonly used bibliometric method for rating academic journals. However, the practice of journals' self-citation may artificially elevate the IF. Additional bibliometric methods including Eigenfactor scale, SCImago Journal Ranking (SJR), and corrected IF (cIF) have been created. Comparing general-interest and specialized orthopaedic journals, the aims of this study were to assess: (1) the effect of journal´s self-citation on IF; (2) differences in bibliometric analysis; and (3) to determine thresholds for monitoring self-citation practices by defining the self-citation in orthopaedic research (SCOR) Threshold. METHODS: The journal citation reports and SCImago Journal and Country Rank databases were queried for orthopaedic journals from 1997 to 2017. The following bibliometrics were compared between general-interest and specialized journals: IF, cIF, Eigenfactor, self-citation rates, and SJR. A novel metric, the cIF ratio, was proposed to represent the relationship between a journal's IF and cIF. Thresholds for cIF were based on statistical outliers of cIF ratio within general-interest and specialized journals were calculated. Outliers were defined as data points that were greater than the third quartile by 1.5 times the interquartile range using the last 10 years studied (2007-2017). RESULTS: Specialized orthopaedic journals had a higher median self-citation rates compared to general-interest journals (11.85% vs. 6.36%, p < 0.001). Overall, cIF ratio declined over study period, and general-interest journals had a lower cIF ratio than specialized journals (8.77% vs. 19.54%, p < 0.001). Overall, general-interest journals had more favourable values for the bibliometric indices studied compared to specialized journals The SCOR threshold for cIF ratio was determined as 25.4% for general-interest journals and 53.3% for specialized journals. CONCLUSION: Overall, self-citation occurs at a higher rate in specialized versus general-interest orthopaedic journals. We propose the use of a cIF ratio along with the SCOR threshold as a tool to evaluate and monitor journal self-citation practices in orthopaedic research.

Cephalomedullary nailing versus sliding hip screws for Intertrochanteric and basicervical hip fractures: a propensity-matched study of short-term outcomes in over 17,000 patients.

BACKGROUND: Hip fractures are associated with poor mortality and morbidity outcomes. Controversy exists over what the preferred treatment is between sliding hips screws (SHSs) and cephalomedullary nails (CMNs) for stable intertrochanteric (IT) and basicervical (BC) hip fractures. The purpose of this study was to compare early postoperative outcomes and complications in patients treated with SHS to those treated with CMN in IT and BC hip fractures. METHODS: We used the National Surgical Quality Improvement Program database to identify IT and BC hip fractures, excluding subtrochanteric hip fractures treated with a SHS and CMN for 2008 to 2016. After propensity score matching, there were 8505 patients in the SHS cohort and 8505 in the CMN cohort. Propensity score-adjusted multivariate regression models assed SHS as an independent risk factor for the following 30-day outcomes: mortality, postoperative major and minor complications, discharge disposition, readmission and reoperation, length of hospital stay (LOS), and operative time. RESULTS: No difference in mortality was encountered between SHS and CMN (p = 0.440). Compared to CMN, the SHS cohort had an 11.6% decreased likelihood of a minor complication (p < 0.001); however, no difference was found between CMN and SHS for major complications (p = 0.117). SHS patients were less likely to have transfusion (p < 0.001), DVT (p = 0.007), and MI (0.024). SHS patients were 12.5% more likely to go home (p = 0.002). No association was discovered between being treated with a SHS and reoperation (p = 0.449) and readmission (p = 0.588). SHS patients had almost a quarter of a day longer LOS (p = 0.041). Patients treated with SHS had a statistically significant (p < 0.001), but clinically irrelevant 2-min longer procedure. LEVEL OF EVIDENCE: III.

Venous Thromboembolism Rates Did Not Decrease in Lower Extremity Revision Total Joint Arthroplasty From 2008 to 2016.

BACKGROUND: In revision total knee arthroplasty (rTKA) and revision total hip arthroplasty (rTHA), venous thromboembolism (VTE) has been reported to be a relatively common and potentially serious complication. To mitigate this risk, strategies such as rapid recovery programs and thromboprophylaxis guidelines have been utilized. This study sought to identify the annual incidence and recent trends of VTE (defined as the presence of deep vein thrombosis [DVT] and/or pulmonary embolism [PE] in the same patient), DVT, PE, and mortality in the 30-day period after rTKA and rTHA. METHODS: We identified 30,406 rTKA and rTHA patients from 2008 to 2016 using the National Surgical Quality Improvement Program database. Thirty-day incidences for VTE, DVT, PE, and mortality for each year and the overall study period were calculated. Bivariate and multivariate regressions were performed using patient demographics and comorbidities to assess trends in the outcomes of interest. RESULTS: The overall incidences of 30-day VTE, DVT, PE, and mortality for rTKA were 1.2%, 0.9%, 0.4%, and 0.5%. Bivariate analysis revealed no significant change over the study period for VTE (P = .137), DVT (P = .406), PE (P = .121; 99% confidence interval 0.112-0.129), and mortality (P = .463). The incidences over the study period of VTE, DVT, PE, and mortality in rTHA were 1.0%, 0.7%, 0.4%, and 0.7%. Bivariate analysis revealed no changes in VTE (P = .393), DVT (P = .376), and PE (P = .602). However, bivariate analysis revealed significant decrease in mortality (P = .010) over the study period. CONCLUSION: Within 30 days of surgery, approximately 1 in 83 rTKA patients and 1 in 100 rTHA patients experienced a VTE. Furthermore, the rates of VTE remained largely unchanged from 2008 to 2016. Further research regarding the optimal individualized prophylaxis algorithm in rTKA and rTHA is warranted to prevent this complication. This study represents the first investigation of thromboembolic events in rTHA and rTKA.

The association between weight-bearing status and early complications in hip fractures.

BACKGROUND: Early mobilization and weight-bearing have been proposed to improve hip fracture outcomes. This study aimed to compare early postoperative complications and outcomes of patients who underwent weight-bearing as tolerated (WBAT) on postoperative day one (POD1) with those that did not on: (1) 30-day mortality; (2) 30-day postoperative major and minor complications; (3) length of stay (LOS); and (4) discharge disposition after hip fracture management. METHODS: The NSQIP database was used to identify 7947 hip fracture patients managed with a hemiarthroplasty and internal fixation, sliding hip screw, or cephalomedullary nail, for a total of 5845 patients were allowed to WBAT on POD1. They were compared to patients who were non-WBAT using adjusted multivariate regression models to evaluate the effect of WBAT status on the outcomes above. RESULTS: Among the cephalomedullary nail patients, WBAT on POD1 was associated with a decreased likelihood of mortality. In the cephalomedullary nail and sliding hip screw treatment groups, patients were less likely to experience major and minor complications if they were WBAT on POD1. WBAT patients had shorter LOS in the sliding hip screw and cephalomedullary nail treatment groups. Patients were less likely to be discharged to a non-home facility when WBAT on POD1 regardless of treatment. CONCLUSION: Early weight-bearing after surgical care of hip fracture seems to decrease morbidity and mortality; however, this effect is treatment dependent. These findings further support the need for early mobilization and rapid recovery programs in the care of hip fracture patients. LEVEL OF EVIDENCE: Level III.

Youth motivation as a predictor of treatment outcomes in a community mental health system.

OBJECTIVE: The purpose of this study was to examine the relationship between youth motivation and psychotherapy outcomes in routine community mental health settings. METHOD: One hundred fifty youth, ages 12-17, from three community mental health clinics completed the Youth Outcome Questionnaire and Treatment Support Measure at frequent intervals over the course of treatment. RESULTS: Increases in motivation followed a curvilinear trajectory. On average, youth motivation significantly increased over the course of therapy according to both self- and parent reports (p < .001). The slope for youth motivation over the course of therapy was negatively associated with the slope for mental health symptoms (p < .001). Initial youth motivation did not predict overall change or the rate of change in symptoms. However, there was significant individual variability in patterns of youth motivation. CONCLUSIONS: Our findings demonstrate that youth show increases in motivation over the course of therapy with most gains occurring in the first few sessions. Because increases in motivation over the course of therapy were related to decreases in mental health symptoms, further research is needed to examine how treatment interventions or other factors such as parent motivation may moderate this relationship. Additional research examining the likely complex relationship between initial youth motivation and treatment outcomes in community mental health settings is needed.

Youth self-efficacy domains as predictors of change in routine community mental health services.

OBJECTIVE: This study examined how youth self-efficacy in four domains--Social, Academic Diligence, Academic Proficiency, and Behavioral Regulation--was associated with youth symptoms and psychotherapy outcomes. METHOD: Participants were 104 youth (aged 12-17, mean age 14.6) and their parents/guardians. Youth completed a measure of perceived self-efficacy and the Youth Outcome Questionnaire-Self-Report (YOQ-SR) regularly over the course of treatment; parents/guardians also completed the Youth Outcome Questionnaire. RESULTS: Although none of the self-efficacy domains significantly predicted changes in parent reports of symptoms, individual growth curve models indicated that increases in three of the four self-efficacy domains (Social, Academic Diligence, and Behavioral Regulation) over the course of treatment were associated with concurrent improvements in youth-reported symptoms. CONCLUSIONS: Results suggest that youth self-efficacy warrants further study in relation to change processes in youth mental health services.

Youth psychotherapy change trajectories and early warning system accuracy in a managed care setting.

OBJECTIVES: To examine change trajectories in routine outpatient mental health services for children and adolescents in a managed care setting, and to use these trajectories to test the accuracy of two variations of an early warning system designed to identify cases at risk for deterioration. METHOD: Multilevel modeling procedures were used to examine longitudinal Youth Outcome Questionnaire (YOQ) data for 16,091 youth aged 4-17 years (39% female, mean age 10.5) referred for treatment in a managed care system. RESULTS: Clients with more frequent YOQ administrations had slightly lower baselines and faster rates of change. Both the traditional and simplified versions of the early warning system demonstrated good accuracy in identifying clients who deteriorated, with a sensitivity of .63, specificity of .83, and hit rate of .81. CONCLUSIONS: Results provide further evidence that patient-focused early warning systems can accurately identify most youth who are at risk for negative outcomes in routine mental health services.

Do patient-reported outcome measures improve after aseptic revision total hip arthroplasty?

BACKGROUND: The purpose of this study was to determine patient-reported outcome measures (PROMs) changes in: (1) pain, function and global health; and (2) predictors of PROMs in patients undergoing aseptic revision total hip arthroplasty (rTHA) using a multilevel model with patients nested within surgeon. METHODS: A prospective cohort of 216 patients with baseline and 1-year PROMs who underwent aseptic rTHA between January 2016 and December 2017 were analysed. The most common indication for rTHA was aseptic loosening, instability, and implant failure. The PROMs included in this study were HOOS Pain and HOOS Physical Function Short-form (PS), Veterans RAND-12 Physical Component Score (VR-12 PCS), and VR-12 Mental Component Score (MCS). Multivariable linear regression models were constructed for predicting 1-year PROMs. RESULTS: Mean 1-year PROMs improvement for aseptic revisions were 30.4 points for HOOS Pain and 22.1 points for HOOS PS. Predictors of better pain relief were patients with higher baseline pain scores. Predictors of better 1-year function were patients with higher baseline function and patients with a posterolateral hip surgical approach during revision. Although VR-12 PCS scores had an overall improvement, nearly 50% of patients saw no improvement or had worse physical component scores. Only 30.7% of patients reported improvements in VR-12 MCS. CONCLUSIONS: Overall, patients undergoing aseptic rTHA improved in pain and function PROMs at 1 year. Although global health assessment improved overall, nearly half of aseptic rTHA patients reported no change in physical/mental health status. The associations highlighted in this study can help guide the shared decision-making process by setting expectations before aseptic revision THA.
