Incidence and risk factors of blood transfusion after total knee arthroplasty: A retrospective nationwide inpatient sample database study.

ABSTRACT:

Introduction

Common postoperative complications of total knee arthroplasty (TKA) include blood transfusion. Although risk factors and incidence of blood transfusion have been studied through national databases, the relative impact of each risk factor needs to be synthesized over a longer time period into a new model need to be revised.

Material and methods

Patient data were extracted from the National Inpatient Sample (NIS), which is the largest hospital care database in the US, and analyse patient data retrospectively from 2010 through 2019. The final data included the patients undergoing TKA. The final analysis assessed the demographics of patients, type of insurance, type of hospital, length of stay (LOS), preoperative comorbidities, total charge, inpatient mortality, medical-surgical postoperative complications.

Results

After extracting data from the NIS database, a total of 1,250,533 patients with TKA were included in the analysis, and the rate of transfusion was 6.60 %. TKA patients who receive blood transfusion had longer LOS (from 2-3 days to 3-4 days), more preoperative comorbidities, higher inpatient mortality rate, and increased total charge (P < 0.001). Moreover, postoperative complications associated with inpatients included sepsis, acute myocardial infarction and shock. Elective admission and private insurance were also regarded as protective factors.

Conclusion

Blood transfusion could bring postoperative complications to patients, which were also linked to health costs and risks. It was also a common preoperative comorbidities for older patients who underwent TKA. Through better blood management strategies, we could reduce patient transfusion rates and improve clinical outcomes.Level of Evidence: Diagnostic Level Ⅲ.

Project description:BACKGROUND:Postoperative delirium is a common complication following major surgeries, leading to a variety of adverse effects. However, there is a paucity of literatures studying the incidence and risk factors associated with delirium after primary elective total hip arthroplasty (THA) using a large-scale national database. METHODS:A retrospective database analysis was performed based on Nationwide Inpatient Sample (NIS) from 2009 to 2014. Patients who underwent primary elective THA were included. Patient demographics, preoperative comorbidities, length of hospital stay (LOS), total charges, in-hospital mortality, and major and minor perioperative complications were evaluated. RESULTS:A total of 388,424 primary elective THAs were obtained from the NIS database, and the general incidence of delirium after THA was 0.90%. Patients with delirium after THA presented more preoperative comorbidities, longer LOS, extra hospital charges, and higher in-hospital mortality rate (P?<?0.001). Delirium following THA was associated with major complications during hospitalization including acute renal failure and pneumonia. Preoperative risk factors associated with postoperative delirium included advanced age, alcohol or drug abuse, depression, neurological disorders, psychoses, fluid and electrolyte disorders, diabetes, weight loss, deficiency anemia, coagulopathy, hypertension, congestive heart failure, valvular disease, pulmonary circulation disorders, peripheral vascular disorders, and renal failure. Both female and obesity were detected to be protective factors. CONCLUSIONS:The results of our study identified a relatively low incidence of delirium after primary elective THA, which is as reported in the NIS and not necessarily the surgical population as a whole. Postoperative delirium of THA was associated with increased preoperative comorbidities, LOS, total charges, in-hospital mortality, and major perioperative complications including acute renal failure and pneumonia. It is of benefit to study risk factors associated with postoperative delirium to moderate its consequences.

Project description:BackgroundTo study the impact of valvular heart disease (VHD) on hip replacement, particularly the clinical impactions of aortic stenosis before total/partial hip arthroplasty.MethodsThis was a retrospective cohort study. Data on patients who had undergone hip replacement from 2005 to 2014 were extracted from the NIS database. Independent t test and chi-square test were used to analyze the essential characteristics of patients. Multivariate regression was used to estimate the correlation among demographics, comorbidities, complications, hospitalization costs, and time.ResultsVHD accounted for 5.56% and AS accounted for 0.03% of the patients before hip replacement surgeries. Patients with VHD before hip replacement are related to the following characteristics: female patients (odds ratio [OR] = 1.15 [1.12-1.18]), elective admission (OR = 0.78 [0.76-0.80]), Charlson Comorbidity Index ≥3 (OR = 1.06 [1.03-1.08]), large-volume hospitals (OR = 1.13 [1.1-1.2]), teaching hospitals (OR = 5 4.4 [2.9-6.7]), and hospital location in urban areas (OR = 1.22 [1.2-1.3]). In addition, VHD is a risk factor for mortality and some acute postoperative medical complications, such as acute cardiac event (OR = 2.96 [2.87-3.04]), acute pulmonary edema (OR = 1.13 [1.06-1.21]), acute cerebrovascular event (OR = 1.22 [1.16-1.74]), and acute renal failure (OR = 1.22 [1.17-1.27]). It also has an impact on DVT/PE (OR = 0.89 [0.8-0.99]). Patients with AS before hip replacement have basic demographic characteristics like those of hip replacement patients with valvular disease. Patients with AS are older than those without AS before surgery (OR = 3.28 [2.27-4.75) and are related to the following characteristics: female patients (OR = 1.92 [1.32-2.8]) and elective admission (OR = 0.51 [0.36-0.75]). The perioperative period is limited to acute postoperative complications, such as acute cardiac events (OR = 2.50 [1.76-3.53]) and acute hepatic failure (OR = 7.69 [1.8-32.89]). Both valvular diseases and AS are associated with a higher mortality rate and hospitalization cost.ConclusionVHD independently predicted mortality rate and surgical and medical complications after total/partial hip arthroplasty.

Project description:BackgroundWith the rising prevalence of abdominal radical hysterectomy, the need for perioperative blood transfusion has emerged as a significant clinical challenge. Independent risk factors for blood transfusion during abdominal radical hysterectomy remains limited, and identifying these factors is needed.MethodsA retrospective analysis of data was performed using the Nationwide Inpatient Sample (NIS), focusing on patients who underwent abdominal radical hysterectomy between 2010 and 2019. Patients were categorized into two groups based on whether they received a blood transfusion. The analysis encompassed various demographic factors, including race, sex, and age, as well as length of stay (LOS), total hospitalization charges, hospital characteristics (admission type, insurance type, bed size, teaching status, geographic location, and hospital region), hospital mortality rates, comorbidities, and perioperative complications. Subsequently, both univariate and multivariate logistic regression analyses were employed to ascertain factors associated with abdominal radical hysterectomy patients requiring blood transfusions.ResultsBlood transfusions occurred in 14.84% of patients between 2010 and 2019, with a downward trend over time. Receiving a transfusion was associated with several negative outcomes, including a longer length of stay, higher total charges, and complications like thrombocytopenia, acute myocardial infarction, pneumonia, and so on. Additionally, patients who received transfusions were more likely to experience postoperative delirium, deep vein thrombosis, and wound infection. Independent risk factors for blood transfusion include Black race, Asian or Pacific Islander race, non-elective surgery, hospitalization in a rural setting, pre-existing medical conditions like coagulopathy, chronic blood loss anemia, deficiency anemia and others. Conversely, patients with private insurance, residing in the West, or Midwest/North Central regions were less likely to require a blood transfusion.ConclusionOur study highlights the concern of perioperative blood transfusion in radical hysterectomy, linked to significant complications. Reducing intraoperative blood loss and optimizing care based on patient factors are crucial for improving outcomes.
