Abstract
Objective
To assess the predictive utility of the Risk Analysis Index (RAI) for in-hospital mortality, discharge disposition, extended length of stay (eLOS), and shunt failure in patients with non-NPH hydrocephalus (including obstructive and communicating subtypes) undergoing first-time shunt placement.
Methods
We performed a retrospective cohort study using Nationwide Inpatient Sample data. Non-NPH patients undergoing first-time shunt placement (ICD-10-CM G91.2) were stratified by RAI score (Normal vs. Frail), a metric previously validated for use with NIS data. Patients were further grouped by payer, race, income quartile, and hydrocephalus subtype. Primary outcomes included extended length of stay, non-home discharge, and in-hospital mortality.
Results
In a cohort of 2525 patients (mean age 43.8 years; 50.5 % female), the majority were White (68.4 %) and privately insured (39.6 %), with 92.0 % treated in large, urban teaching hospitals. Frailty was identified in 21.2 % of the cohort and was strongly associated with eLOS (OR 1.23–2.00), NHD (OR 1.74–2.69), and in-hospital mortality (OR 1.66–14.17). The RAI demonstrated the highest predictive value for mortality (AUC = 0.775) and age for NHD (AUC = 0.733; p < 0.01). Additionally, obstructive hydrocephalus (OR 2.12–3.25) was linked to increased odds of eLOS.
Conclusion
RAI-measured frailty, advanced age, and specific non-NPH subtypes predicted adverse shunt outcomes. These findings support the RAI as a valuable tool for risk stratification and personalized perioperative planning in patients with non-NPH hydrocephalus, particularly in subacute presentations. Its use may help guide shared decision-making and resource preparedness.
