Key result
Severe frailty and complications during admission significantly increased the risk of lower urinary tract infections after major noncardiac surgery (OR 3.46, p<0.05 and OR 9.53, p<0.001, respectively).
Why the study?
There is limited research investigating the relationships between urinary tract infection and associated factors in frail older surgical patients, particularly in Thailand.

Severe frailty and admission complications are strong predictors of lower urinary tract infections in older adults following major noncardiac surgery.
Identifies risk factors for postoperative UTI in frail elderly; leaves open whether targeted prevention improves outcomes in this population.
Urinary tract infections are the most common complication after surgery in older adults, resulting in poor operative outcomes and reduced quality of life after discharge. However, there is limited research investigating the relationships between urinary tract infection and associated factors in frail older surgical patients, particularly in Thailand. This retrospective study included 220 frail older patients aged ≥ 60 years who had undergone major noncardiac surgery at a tertiary care hospital in Thailand from January 2015 to December 2019. The sample was recruited using the criteria indicated in the modified Frailty Index-11 and having the blood glucose level determined within 2 h before surgery. The prevalence of lower urinary tract infections was 15% post-surgery. Firth’s logistic regression analysis revealed that the equation could predict the accuracy of lower urinary tract infections by 88.5%. Frailty, blood glucose levels, complication during admission, and personal factors together predicted the variability of lower urinary tract infections. Adjusting for other variables, being an older adult with severe frailty and complications during hospital admission significantly increased the risk of developing lower urinary tract infections (odds ratio = 3.46, p < 0.05; odds ratio = 9.53, p < 0.001, respectively).

Thangrom et al. (2023) conducted an observational in Frail older adults undergoing major noncardiac surgery (n=220). Severe frailty and complications during admission vs. Absence of severe frailty and complications was evaluated on Lower urinary tract infections (OR 3.46, p=<0.05). Severe frailty and complications during admission significantly increased the risk of lower urinary tract infections after major noncardiac surgery (OR 3.46, p<0.05 and OR 9.53, p<0.001, respectively).
