AbstractDespite advancements in surgical technique and component design, implant loosening, stiffness, and instability remain leading causes of total knee arthroplasty (TKA) failure. Patient-specific instruments (PSI) aid in surgical precision and in implant positioning and ultimately reduce readmissions and revisions in TKA. The objective of the study was to evaluate total hospital cost and readmission rate at 30, 60, 90, and 365 days in PSI-guided TKA patients. We retrospectively reviewed patients who underwent a primary TKA for osteoarthritis from the Premier Perspective Database between 2014 and 2017 Q2. TKA with PSI patients were identified using appropriate keywords from billing records and compared against patients without PSI. Patients were excluded if they were < 21 years of age; outpatient hospital discharges; evidence of revision TKA; bilateral TKA in same discharge or different discharges. 1:1 propensity score matching was used to control patients, hospital, and clinical characteristics. Generalized Estimating Equation model with appropriate distribution and link function were used to estimate hospital related cost while logistic regression models were used to estimate 30, 60, and 90 days and 1-year readmission rate. The study matched 3,358 TKAs with PSI with TKA without PSI patients. Mean total hospital costs were statistically significantly (p < 0.0001) lower for TKA with PSI ($14,910; 95% confidence interval [CI]: $14,735–$15,087) than TKA without PSI patients ($16,018; 95% CI: $15,826–$16,212). TKA with PSI patients were 31% (odds ratio [OR]: 0.69; 95% CI: 0.51–0.95; p-value = 0.0218) less likely to be readmitted at 30 days; 35% (OR: 0.65; 95% CI: 0.50–0.86; p-value = 0.0022) less likely to be readmitted at 60 days; 32% (OR: 0.68; 95% CI: 0.53–0.88; p-value = 0.0031) less likely to be readmitted at 90 days; 28% (OR: 0.72; 95% CI: 0.60–0.86; p-value = 0.0004) less likely to be readmitted at 365 days than TKA without PSI patients. Hospitals and health care professionals can use retrospective real-world data to make informed decisions on using PSI to reduce hospital cost and readmission rate, and improve outcomes in TKA patients.

AbstractGiven a national push toward bundled payment models, the purpose of this study was to examine the prevalence as well as the effect of smoking on early inpatient complications and cost following elective total knee arthroplasty (TKA) in the United States across multiple years. Using the nationwide inpatient sample, all primary elective TKA admissions were identified from 2012 to 2014. Patients were stratified by smoking status through a secondary diagnosis of “tobacco use disorder.” Patient characteristics as well as prevalence, costs, and incidence of complications were compared. There was a significant increase in the rate of smoking in TKA from 17.9% in 2012 to 19.2% in 2014 (p < 0.0001). The highest rate was seen in patients < 45 years of age (27.3%). Hospital resource usage was significantly higher for smokers, with a length of stay of 3.3 versus 2.9 days (p < 0.0001), and hospital costs of $16,752 versus $15,653 (p < 0.0001). A multivariable logistic model adjusting for age, gender, and comorbidities showed that smokers had an increased odds ratio for myocardial infarction (5.72), cardiac arrest (4.59), stroke (4.42), inpatient mortality (4.21), pneumonia (4.01), acute renal failure (2.95), deep vein thrombosis (2.74), urinary tract infection (2.43), transfusion (1.38) and sepsis (0.65) (all p < 0.0001). Smoking is common among patients undergoing elective TKA, and its prevalence continues to rise. Smoking is associated with higher hospital costs as well as higher rates of immediate inpatient complications. These findings are critical for risk stratification, improving of bundled payment models as well as patient education, and optimization prior to surgery to reduce costs and complications.

Acid Administration

Aim: Total knee arthroplasty is a kind of major orthopaedic operation that may go with serious amount of peroperative blood loss. Tranexamic acid administration (an antifibrinolytic agent) is one of the most common strategy among the various blood preserving strategies used in major surgeries associated with high volume blood loss. The aim of this study is to evaluate effectiveness of oral tranexamic acid in reducing blood loss and blood transfusion in total knee arthroplasty procedures. In addition hospital costs were also compared. Materials-Methods: Between 2013-2016, 256 total knee arthroplasty procedure performed by six different staff surgeons in our clinic. 125 patients appropriate for our study criteria were included in our study and retrospectively evaluated. 49 patients in study group were administered 15 mg/kg tranexamic intravenous infusion before relasing intraoperative tourniquet and continued as oral 500 mg tranexamic acid three times with 6 hours interval in the first postoperative 24 hours.76 patients were not administered tranexamic acid and compromised the control group. Information on pateints’s demographics, preoperative and postoperative 24th hour hemoglobin and hematocrit values, postoperative 24th hour drain volumes and blood transfusions were obtained from patient files retrospectively. Results: Postoperative 24th hour drain volumes were significiantly less in tranexamic acid administered group (283 130 cc) than that of control group (383 135 cc) (p<0,001). Decrease in hemoglobin and hematocrit values in the postoperative 24th hour were significiantly less in study group (1,73 g/dL-%6,13) than those of control group (2,92 g/dL -%8,63) (P<0,001). Both number of total erythrocyte suspensions (ES) transfused and number of patients transfused were higher in control group than those of study group. (52 ES and 45 patients versus 18 ES and 14 patients) Calculated average ES per patient were 0.37 in study group and 0.68 in control group. (P=0,009). As a result blood bank costs were reduced %50 in study group as compared to control group. Conclusions: Tranexamic acid administered as single intraoperative intravenous dose and sequentially continued as 500 mg oral dosage 3 times with six hours interval in the first postoperatve24 hours is a significiantly effective approach in preventing bloos loss and reducing hospital costs in total knee arthroplasty procedures. In addition easiness and convinience of oral administration of tranexamic acid makes the approach more advantageous.

Chi Square Analysis

AbstractAs obesity in the United States increases, the proportion of obese and morbidly obese patients undergoing same-day bilateral total knee arthroplasty (sd-BTKA) remains unknown. Therefore, this study analyzed: (1) incidence, (2) patient demographics, (3) patient course, and (4) patient outcomes in obese and morbidly obese patients undergoing sd-BTKA in the United States from 2009 to 2016. The National Inpatient Sample was queried for all sd-BTKA patients from 2009 to 2016, yielding 39,901 obese and 20,394 morbidly obese patients. Analyzed variables included overall incidence, age, length of stay (LOS), sex, race, payer, Charlson comorbidity index (CCI) status, disposition, complications, location/teaching status, region of hospital, costs, and charges. Categorical variables were evaluated with chi-square analysis, while continuous variables were analyzed by Student's t-tests. Overall, the number of sd-BTKAs decreased over the study period, although the proportion of both obese and morbidly obese patients increased (p < 0.001 for all). The most common CCI status, 3 + , decreased in proportion for both groups (p < 0.001 for all). Hospital costs decreased and charges increased for both groups (p < 0.001 for all). Mean LOS decreased and patients were most commonly discharged to skilled nursing facilities, although these proportions decreased (p < 0.001 for all). Respiratory failures (p < 0.001 for all) increased for both groups, while proportion of deep vein thromboses and hematomas/seromas (p < 0.001 for all) increased for obese patients and proportion of pulmonary emboli (p < 0.001) increased for morbidly obese patients. The results of this study appear to portray improving optimization and patient selection of higher body mass index (BMI) individuals undergoing this procedure. More information is needed comparing the safety of the sd-BTKA across patients of all BMI groups.
