ABSTRACT
BACKGROUND:
The prevalence of neurocognitive dysfunction (NCD) and its effects on postoperative outcomes have not been well characterized following total joint arthroplasty (TJA) population. This study aims at better understand this relationship.METHODS:
Patients were evaluated for neurocognitive function using the grooved pegboard test for the dominant (PEG-D) and nondominant hand (PEG-N), and the Rey Auditory Verbal Learning Test (RAVLT). The patient scores for each test was compared to age-controlled normative values in order to identify NCD. Baseline characteristics and postoperative outcomes were then compared amongst the two cohorts.RESULTS:
Ninety-nine consecutive patients were prospectively enrolled. Nearly 54% were identified as neurocognitively deficient on at least 1 of the 3 tests (31% by RAVLT, 21% by PEG-D, and 30% by PEG-N). There was a statistically significant prevalence of NCD in patients older than 60 years when compared to normative controls for RAVLT (P < .001). Patients with depression or an American Society of Anesthesiologist score of 3 were 5 times as likely to have NCD, while patients with a body mass index between 20-30 kg/m2 were 5 times less likely to have NCD. Furthermore, patients identified as NCD preoperatively were significantly more likely to be transferred to the intensive care unit (48% vs 14%) and fail physical therapy (64% vs 17%), respectively.CONCLUSION:
NCD is highly prevalent within total joint arthroplasty candidates and may be correlated with higher body mass index, American Society of Anesthesiologist scores, and rates of depression. The condition predisposes patients to suboptimal postoperative outcomes including increased intensive care unit admissions and prolonged rehabilitation.Palavras-chave
