BACKGROUND:Managing patients with hydrocephalus and cerebrospinal fluid (CSF) disorders requires repeated head imaging. In adults, it is typically computed tomography (CT) or less commonly magnetic resonance imaging (MRI). However, CT poses cumulative radiation risks and MRI is costly. Ultrasound is a radiation-free, relatively inexpensive, and optionally point-of-care alternative, but is prohibited by very limited windows through an intact skull.OBJECTIVE:To describe our initial experience with transcutaneous transcranial ultrasound through sonolucent burr hole covers in postoperative hydrocephalus and CSF disorder patients.METHODS:Using cohort study design, infection and revision rates were compared between patients who underwent sonolucent burr hole cover placement during new ventriculoperitoneal shunt placement and endoscopic third ventriculostomy over the 1-year study time period and controls from the period 1 year before. Postoperatively, trans-burr hole ultrasound was performed in the clinic, at bedside inpatient, and in the radiology suite to assess ventricular anatomy.RESULTS:Thirty-seven patients with sonolucent burr hole cover were compared with 57 historical control patients. There was no statistically significant difference in infection rates between the sonolucent burr hole cover group (1/37, 2.7%) and the control group (0/57, P = .394). Revision rates were 13.5% vs 15.8% (P = 1.000), but no revisions were related to the burr hole or cranial hardware.CONCLUSION:Trans-burr hole ultrasound is feasible for gross evaluation of ventricular caliber postoperatively in patients with sonolucent burr hole covers. There was no increase in infection rate or revision rate. This imaging technique may serve as an alternative to CT and MRI in the management of select patients with hydrocephalus and CSF disorders.

This study was conducted to enhance the rate of advance care planning (ACP) conversations and documentation in a dementia specialty practice by increasing physician knowledge, attitudes, and skills. We used a pre- and postintervention paired design for physicians and 2 independent groups for patients. The ACP dementia educational program encompassed 3 objectives: (1) to understand the relevance of ACP to the dementia specialty practice, (2) to provide a framework to discuss ACP with patients and caregivers, and (3) to discuss ways to improve ACP documentation and billing in the electronic medical record. A 10-item survey was utilized pre- and posteducational intervention to assess knowledge, attitudes, and skill. The prevalence of ACP documentation was assessed through chart review 3 months pre- and postintervention. The educational intervention was associated with increased confidence in ability to discuss ACP ( P = .033), belief that ACP improves outcomes in dementia ( P = .035), knowledge about ACP Medicare billing codes and requirements ( P = .002), and belief that they have support from other personnel to implement ACP ( P = .017). In 2 independent groups of patients with dementia, documentation rates of an advance directive increased from 13.6% to 19.7% ( P = .045) and the Medical Order for Life-Sustaining Treatment (MOLST) increased from 11.0% to 19.0% ( P = .006). The MOLST documentation in 2 independent groups of patients with nondementia increased from 7.3% to 10.7% ( P = .046). Continuing efforts to initiate educational interventions are warranted to increase the effectiveness ACP documentation and future care of persons with dementia.
