Abstract
The demand for total hip arthroplasty (THA) continues to rise. While prior work has examined frailty and malnutrition independently, the additive effects of these conditions are unknown. Therefore, the purpose of this study was to evaluate the individual and combined influence of malnutrition and frailty in the elective THA patient.
This is a retrospective cohort study. Patients undergoing elective, primary THA were identified from the American College of Surgeons-National Surgery Quality Improvement Program database. Patients with hip fracture were excluded. Preoperative serum albumin levels (malnutrition = albumin <3.5 g/dL) and 5-item modified frailty index scores (≥2 = frail) were collected. Four cohorts were created: (1) Healthy (N), (2) Frail-only (F), (3) Hypoalbuminemia-only (H), and (4) Hypoalbuminemia and frail (HF). Demographic and complication data were collected, and statistical analysis was performed comparing complications between cohorts.
105,997 patients undergoing THA were identified for inclusion. The majority (82%) of patients were healthy (14% F, 3% H, and 1% HF). The HF group was found to have higher odds of complication compared with all other groups (HF vs N; odds ratio [OR] 3.7, 95% confidence interval [CI] 3.07-4.46, P < .001). Notably, patients in the HF cohort had a 1.9% 30-day mortality rate (HF vs N; OR 12.66, 95% CI 7.81-20.83, P < .001). Additionally, HF patients had higher odds of increased resource utilization when compared with all other groups (P < .001).
Frailty and malnutrition both represent physiologically compromised states but are only weakly correlated. The concurrent presence of frailty and malnutrition in the THA patient has significant detrimental impacts. Further research will be needed to delineate to what degree these risk factors are modifiable.
