ABSTRACT

Introduction:

Implantable telemetric intracranial pressure sensors (telesensors) enable routine, non-invasive ICP feedback which can assist with clinical decision-making and attribution of pressure-related symptoms in patients with CSF shunt systems. Here, we aim to characterise telesensor cost-effectiveness and impact on service demand.

Methods:

A single-centre, retrospective, cohort study and costeffectiveness analysis of 80 patients (78% Female;30% IIH, 22% Chiari malformation, 48% other) with MScio® (Christoph Miethke) telemetric ICP monitors. Service demand in the two years before and after implantation were retrieved from the centre's electronic patient record system. Intentionally, data did not overlap with the COVID-19 pandemic period. The frequencies of hydrocephalusrelated neurosurgical admissions, outpatient clinics, and scans were recorded along with A&E, neurology, and ophthalmology encounters. Tariffs were used to compare expenditure before and after implantation.

Results:

Significant reductions were seen in the frequencies of neurosurgical admissions (1.9/year to 0.6;p < 0.001), ICP monitoring (0.4 to 0.01;p < 0.001), and CT scans (0.5 to 0.3;p = 0.013) following implantation. There were also significant reductions in the proportion of patients requiring admissions (91% to 45%;p < 0.001) and ICP monitoring (30% to 3%;p < 0.001). There were non-significant reductions in other invasive procedures, neurology encounters, and A&E admissions. Overall, there was a £341 (SD = 1069) per patient per year saving (22% reduction in included costs).

Conclusions:

From an institutional perspective, the implantation of telesensors contributes to a reduction in service demand and a net financial saving. From a patient perspective, fewer appointments, invasive procedures, and radiation exposures suggest an improvement in patient experience and safety.
