Impact of standardized care guidelines featuring next-day discharge on outcome, healthcare consumption, and patient healthcare experience in patients with idiopathic normal pressure hydrocephalus receiving ventriculoperitoneal shunts

Abstract

OBJECTIVE The aim of this study was to evaluate the effect of standardized care guidelines featuring next-day discharge on hospital length of stay (LOS), outcomes, patient experience, and healthcare consumption in patients receiving ventriculoperitoneal shunts (VPSs) for idiopathic normal pressure hydrocephalus (iNPH). METHODS This single-center population-based observational cohort study included 271 adult iNPH patients who underwent VPS surgery at Karolinska University Hospital. Groups were compared before and after the implementation of new standardized discharge guidelines. The primary outcome was the hospital LOS. Secondary outcomes included postoperative complications, patient experience, and frequency of unscheduled outpatient follow-up appointments. RESULTS A total of 121 patients were treated with variable hospitalization periods. One hundred fifty patients were managed under the new guidelines stipulating next-day discharge. There was no significant difference in positive surgical outcome (66% vs 71%, p = 0.372) or rates of complication (p ≥ 0.066) between groups. The standardized guidelines group had a significantly shorter period of inpatient hospitalization (1 vs 2 days, p < 0.001) and demonstrated lower levels of unscheduled outpatient healthcare consumption (p < 0.001) while maintaining levels of positive patient experience (p = 0.828). CONCLUSIONS Standardized discharge guidelines featuring next-day discharge are safe for iNPH patients undergoing VPS surgery, maintain the quality of the patient experience, and are an effective method for mitigating healthcare consumption in an expanding patient group.
