# Risk assessment for postoperative complications in patients undergoing cardiac surgical procedures

## TL;DR

This study assesses the risk of post-surgery complications in heart surgery patients using the Tuman Score to improve preoperative care.

## Contribution

The study applies the Tuman Score to evaluate postoperative complication risks in cardiac surgery patients using Quasi-Poisson regression.

## Key findings

- Patients aged 41-64 and undergoing myocardial revascularization had lower complication risks.
- High-risk patients faced higher rates of pulmonary and neurological complications.
- Preoperative risk assessment using the Tuman Score can help reduce postoperative complications.

## Abstract

to evaluate the risk of postoperative complications in cardiac patients.

an evaluative study using the Tuman Score on medical records of 70 adult patients who underwent cardiac surgery at a University Hospital. The R for Windows software was used for the analyses. Descriptive statistics and bivariate analysis were employed to verify the association between the risk score and complications. The relative risk between the Tuman Score and postoperative complications was obtained through Quasi-Poisson regression, with a 95% confidence interval.

the majority of the patients were male (58.57%), aged between 41-64 years (50%), who underwent myocardial revascularization (50%). These patients were associated with a lower risk of postoperative complications (p=0.003), (p=0.008), and (p=0.000), respectively. High-risk patients had pulmonary complications (RR=1.32, p=0.002) and neurological complications (RR=1.20, p=0.047).

preoperative risk assessment promotes qualified care to reduce postoperative complications.

avaliar o risco de complicações pós-operatórias em pacientes cardíacos.

pesquisa avaliativa, utilizando o Escore de Tuman, em prontuários de 70 pacientes adultos submetidos a cirurgia cardíaca em um Hospital Universitário. Foi utilizado o software R for Windows para as análises. A estatística descritiva e a análise bivariada foram utilizadas para verificar a associação entre escore de risco e complicações. O risco relativo entre o Escore de Tuman e as complicações pós-operatórias foi obtido por meio de regressão Quasi-Poisson, com intervalo de confiança de 95%.

predominou paciente do sexo masculino (58,57%), com idades entre 41-64 anos (50%), que realizaram Revascularização do Miocárdio (50%), e esses foram associados ao menor risco de complicações pós-operatórias (p=0,003), (p=0,008) e (p=0,000), respectivamente. Os pacientes de alto risco tiveram complicações pulmonares (RR=1,32 e p=0,002) e complicações neurológicas (RR=1,20 e p=0,047).

a avaliação dos riscos pré-operatórios promove uma assistência qualificada para reduzir as complicações pós-operatórias.
