Safety and outcomes of hip and knee replacement surgery in liver transplant recipients

BACKGROUND Liver transplant(LT)is becoming increasingly common with improved life expectancy.Joint replacement is usually a safe procedure;however,its safety in LT recipients remains understudied.AIM To evaluate the mortality,outcome,and 90-d readmission rate in LT patients undergoing hip and knee replacement surgery.METHODS Patients with history of LT who underwent hip and knee replacement surgery between 2016 and 2019 were identified using the National Readmission Database.RESULTS A total of 5046119 hip and knee replacement surgeries were identified.3219 patients had prior LT.Mean age of patients with no history of LT was 67.51[95%confidence interval(CI):67.44-67.58],while it was 64.05(95%CI:63.55-64.54)in patients with LT.Patients with history of LT were more likely to have prolonged length of hospital stay(17.1%vs 8.4%,P<0.001).The mortality rate for patients with no history of LT was 0.22%,while it was 0.24%for patients with LT(P=0.792).Patients with history of LT were more likely to have re-admissions within 90 d of initial hospitalization:11.4%as compared to 6.2%in patients without history of LT(P<0.001).The mortality rate between both groups during readmission was not statistically different(1.9%vs 2%,P=0.871)respectively.CONCLUSION Hip and knee replacements in patients with history of LT are not associated with increased mortality;increased readmissions were more frequent in this cohort of patients.Chronic kidney disease and congestive heart failure appear to predict higher risk of readmission.

Hospitalizations for alcoholic liver disease during the COVID-19 pandemic increased more for women,especially young women,compared to men

BACKGROUND Alcoholic liver disease(ALD)remains one of the major indications for liver transplantation in the United States and continues to place a burden on the national healthcare system.There is evidence of increased alcohol consumption during the coronavirus disease 2019(COVID-19)pandemic,and the effect of this on the already burdened health systems remains unknown.AIM To assess the trends for ALD admissions during the COVID-19 pandemic,and compare it to a similar pre-pandemic period.METHODS This retrospective study analyzed all admissions at a tertiary health care system,which includes four regional hospitals.ALD admissions were identified by querying a multi-hospital health system’s electronic database using ICD-10 codes.ALD admissions were compared for two one-year periods;pre-COVID-19 from April 2019 to March 2020,and during-COVID-19 from April 2020 to March 2021.Data were analyzed using a Poisson regression model and admission rates were compared using the annual quarterly average for the two time periods,with stratification by age and gender.Percent increase or decrease in admissions from the Poisson regression model were reported as incident rate ratios.RESULTS One thousand three hundred and seventy-eight admissions for ALD were included.80.7%were Caucasian,and 34.3%were female.An increase in the number of admissions for ALD during the COVID-19 pandemic was detected.Among women,a sharp rise(33%)was noted in those below the age of 50 years,and an increase of 22%in those above 50 years.Among men,an increase of 24%was seen for those below 50 years,and a 24%decrease in those above 50 years.CONCLUSION The COVID-19 pandemic has had widespread implications,and an increase in ALD admissions is just one of them.However,given that women are often prone to rapid progression of ALD,this finding has important preventive health implications.
