OBJECTIVES/OBJECTIVE:Analyze the effectiveness of a BPCI (Bundle Payments for Care Improvement) initiative at a large urban medical center for hip fracture patients included in the bundle payment program with respect to improving patient outcomes and reducing cost DESIGN:: Retrospective cohort SETTING:: Single Academic Institution PATIENTS/PARTICIPANTS:: Patients discharged with the DRG codes 469-470 performed for hip fractures between July 2011 and September 2014 were evaluated. A BPCI initiative focused on optimizing care coordination, patient education, expectations, and minimizing post-acute facility and resource utilization was initiated in October 2013. Patient outcomes prior to the introduction of the BPCI initiative were compared to those who participated in the initiative. INTERVENTION/METHODS:Application of BPCI principles MAIN OUTCOME MEASURES:: length of stay, location of discharge, readmission within 90 days, and 90-day episode of care costs RESULTS:: Sixty-one patients received care prior to the initiative, and forty-four patients were treated with the initiative. The mean length of stay decreased from 6.8 to 5.3 days and the percentage of patients discharged home increased by nearly 10% with the introduction of the BPCI initiative (6.6% vs. 15.9%). There was a 13.1% reduction in total 90-day episode of care cost ($57,546 vs. $49,993, p=0.210) upon introduction of the initiative. There was no significant difference in readmission rate between the two cohorts. CONCLUSION/CONCLUSIONS:This study demonstrates the success of one such program for hip fracture arthroplasty patients aimed at care coordination and minimizing post-acute hospitalization facility care both with respect to improved patient outcomes and substantial cost reduction. LEVEL OF EVIDENCE/METHODS:Therapeutic Level IV.

BACKGROUND:Socioeconomic disparities are an inherent and currently unavoidable aspect of medicine. Knowledge of these disparities is an essential component towards medical decision making, particularly among an increasingly diverse population. While healthcare disparities have been elucidated in a wide variety of orthopaedic conditions and management options, they have not been established among patients who present for treatment of an ununited fracture. The purpose of this study is to answer the following questions: 1) Following surgical management of (fracture) non-unions, are there differences in outcomes between differing ethnic groups? 2) Following surgical management of (fracture) non-unions, are there differences in outcomes between patients with differing education levels? 3) Following surgical management of (fracture) non-unions, are there differences in outcome between patients with differing incomes? METHODS:Between September 2004 and December 2017, operatively treated patients who presented with a long bone fracture non-union were prospectively followed. These patients presented with a variety of fracture non-unions that underwent surgical intervention. Sociodemographic factors were recorded at presentation. Long-term outcomes were evaluated using the Short Musculoskeletal Function Assessment (SMFA), pain scores, post-operative complications and physical exam at latest follow up. The SMFA is a 46-item questionnaire, assessing patient functional and emotional response to musculoskeletal ailments. RESULTS:Three-hundred-twenty-nine patients met inclusion criteria. Patients with a lower education had worse long-term functional outcomes (P < 0.001) and increased pain scores (P = 0.002) at latest follow-up. Patients who made less than $50,000 annually had worse long-term functional outcomes (P = 0.002) and reported higher pain scores (P = 0.003) following surgical management of (fracture) non-unions. Multiple linear regression demonstrated education level to be an independent predictor of long-term functional outcomes following surgical management of (fracture) non-unions (B= -0.154, 95% Confidence Interval [CI]=-10.96 to -1.26, P = 0.014). No differences existed in outcomes or pain scores between those of different ethnic groups. No differences existed regarding post-operative complications and time to union between patients of different ethnic groups, educational levels and income status. CONCLUSION/CONCLUSIONS:Patients with lower education levels and individuals who make less than $50,000 annually have worse functional outcomes following surgical management of (fracture) non-unions. Orthopaedic trauma surgeons should therefore be aware of these disparities, and consider early interventions aimed at optimizing patient recovery in these subsets.

The purpose of this study was to analyze the perioperative complication rate and inpatient hospitalization costs associated with hip fractures in patients older than 90 years compared with patients younger than 90 years. Patients 60 years and older with hip fractures treated operatively at 1 academic medical center between October 2014 and September 2016 were analyzed. Patient demographics, comorbidities, length of stay, procedure performed, and inpatient complications were analyzed. Total cost of admission was obtained from the hospital finance department. Outcomes were compared between patients older than 90 years and patients younger than 90 years. A total of 500 patients with hip fractures were included in this study. There were 109 (21.8%) patients 90 years and older and 391 (78.2%) patients 60 to 89 years. There was no difference in fracture pattern, operation performed, Charlson Comorbidity Index, or length of stay between the 2 groups. The mean length of stay for patients 90 years and older with hip fractures was 7.8±4.3 days vs 7.6±4.2 days for the younger cohort (P=.552). There was no observed difference in perioperative complications. Finally, there was no difference in the total mean cost of admission. Patients 90 years and older are at no greater risk for perioperative complications based on age alone. They are also no more likely to require longer or more costly hospitalizations than patients younger than 90 years. [Orthopedics. 201x; xx(x):xx-xx.].

BACKGROUND:The complication rate of locked plating for proximal humerus fractures remains stubbornly high. The purpose of this study was to determine if a learning curve exists with the operative treatment of proximal humerus fractures. METHODS:We prospectively followed 161 consecutive patients with proximal humerus fractures treated by a single surgeon with locked plates from 2005 to 2016. Radiographic data, functional outcomes, and complications from the surgeon's first 81 patients were compared to the subsequent 80 patients. RESULTS:There was no statistical difference in the rates of complications (p = 0.29) or screw penetration (p = 0.19). There were no differences in DASH scores (p = 0.64 to 0.79) or tip-apex distance (p = 0.40). Head shaft angles were slightly smaller in patients treated earlier in the surgeon's career (p = 0.02). DISCUSSION/CONCLUSIONS:While surgeon experience is certainly a favorable quality, there does not appear to be a significant "learning curve" in the treatment of proximal humerus fractures.

Patterns of discharge location may be evident based on the "sickness" profile of the patient. This study sought to evaluate the ability of the STTGMA tool, a validated mortality risk index for middle-aged and geriatric trauma patients, to predict discharge location in a cohort of low-energy elderly hip fracture patients, with successful discharge planning measured by readmission rates. Low-energy hip fracture patients aged 55 years and older were prospectively followed throughout their hospitalization. On initial evaluation in the Emergency Department, each patient's age, comorbidities, injury severity, and functional status were utilized to calculate a STTGMA score. Discharge location was recorded with the primary outcome measure of an unsuccessful discharge being readmission within 30 days. Patients were risk stratified into minimal-, low-, moderate-, and high-risk STTGMA cohorts. A p-value of <0.05 was considered significant for all statistical tests. 408 low-energy hip fractures were enrolled in the study with a mean age of 81.3±10.6 years. There were 214 (52.5%) intertrochanteric fractures, 167 (40.9%) femoral neck fractures, and 27 (6.6%) subtrochanteric femur fractures. There was no difference in readmission rates within STTGMA risk cohorts with respect to discharge location; however, among individual discharge locations there was significant variation in readmission rates when patients were risk stratified. Overall, STTGMA risk cohorts appeared to adequately risk-stratify readmission with 3.5% of minimal-risk patients experiencing readmission compared to 24.5% of moderate-risk patients. Specific cohorts deemed high-risk for readmission were adequately identified. The STTGMA tool allows for prediction of unfavorable discharge location in hip fracture patients. Based on observations made via the STTGMA tool, improvements in discharge planning can be undertaken to increase home discharge and to more closely track "high-risk" discharges to help prevent readmissions.

Introduction/UNASSIGNED:The purpose of this study was to analyze the effect of the admitting service on cost of care for hip fracture patients by comparing the cost difference between patients admitted to the medicine service versus those admitted to a surgical service. Methods/UNASSIGNED:value of <.05 as significant. Results/UNASSIGNED:= .034) compared to patients admitted to the medicine service. Discussions/UNASSIGNED:In our urban safety net hospital, hip fracture patients admitted to medicine service had longer lengths of stay and higher total hospitalization costs than patients who were admitted to surgery service. Conclusions/UNASSIGNED:This study highlights that the admitting service should be an area of focus for hospitals when developing programs to provide effective and cost-conscious care to hip fracture patients.

The purpose of this study is to evaluate incidence, preoperative laboratory markers, and outcomes of patients who positively cultured pathogens (PCP) at time of surgery for long bone fracture nonunion. Two-hundred and eighty-eight patients were enrolled in a trauma study on long bone nonunion. Two-hundred and sixteen of those 288 patients were cultured at the time of fracture nonunion surgery. Laboratory data were collected prior to intervention and infectious laboratory markers ordered on patients suspected for infection. Patients were followed for one year. Wound complications, antibiotic use, healing, function, and re-admission for further surgery were assessed. Cultures returned positive on 59 patients (representing 20.5% of the 288 patient cohort or 27.3% of the 216 patients cultured in the operative suite). More PCP's (47.5%; 28 of 59) developed wound complications, with greater mean antibiotic duration and more frequent returns to the OR averaging 1.3 procedures per patient. Twelve-month follow-up was obtained on 249 of the 288 (86.5%) and PCPs reported globally worse function. Patients who PCP at the time of operative management for long bone nonunion was a prognostic indicator of poorer long-term functional outcomes.
