Listening Beyond Auscultating: A Quality Initiative to Improve Communication Scores in the Hospital Consumer Assessment of Health Care Practitioners and Systems Survey.

INTRODUCTION: Physician communication is critical to patient care. However, integration of sound communication practice with clinical workflows has proven difficult. In this quality improvement initiative, medical students used the rapid improvement model to test interventions that could enhance patients' perception of listening by physicians as measured by the Hospital Consumer Assessment of Healthcare Providers and Systems survey. METHODS: Literature review and process analysis yielded 42 potential interventions, of which 24 were feasible for implementation. Small-scale testing established the 4 most promising interventions; pilot testing was subsequently undertaken on the entire Medicine service. Patient and physician feedback guided further refinement. The final intervention used a structured reminder embedded in the electronic health record to direct physicians to begin interviews by eliciting patient concerns. RESULTS: Patient concerns elicited after implementation included pain symptoms (28%), disease or treatment course (16%), and discharge planning (10%). In the Hospital Consumer Assessment of Healthcare Providers and Systems survey, physician listening scores rose from a 2014 average of 73.6% to 77% in 2015. DISCUSSION: Among 24 tested interventions, an open-ended question was most feasible and had the greatest perceived impact by hospitalists and patients. A structured reminder embedded in required electronic medical record documentation facilitated the behavioral change without being overly burdensome to physicians and established a mechanism to enact change in practice. CONCLUSION: Medical students used established improvement methods to promote patient-centered care and align patient and physician agendas, providing a strategy to improve hospitalized patients' perceptions of physician listening.

Risk of vigabatrin-associated brain abnormalities on MRI in the treatment of infantile spasms is dose-dependent.

OBJECTIVE: Although the link between vigabatrin (VGB) and retinotoxicity is well known, little attention has been focused on the risk of VGB-associated brain abnormalities on magnetic resonance imaging (MRI) (VABAM), namely reversible-and largely asymptomatic-signal changes in the thalami, basal ganglia, brainstem tegmentum, and cerebellar nuclei. Using a large infantile spasms cohort, we set out to identify predictors of these phenomena. METHODS: Children with infantile spasms were retrospectively identified. Brain MRI reports were serially reviewed without knowledge of VGB exposure. Upon VABAM discovery, records were systematically reviewed to ascertain presence of symptoms attributable to VGB. Separately, progress notes were sequentially reviewed to identify and quantify VGB exposure. RESULTS: We identified 507 brain MRI studies among 257 patients with infantile spasms. VGB treatment was documented in 143 children, with detailed exposure data available for 104, of whom 45 had at least one MRI study during VGB treatment. Among the limited subset of asymptomatic children who underwent MRI (n = 40), 6 exhibited VABAM. Risk of asymptomatic VABAM was dose-dependent, as peak (but not cumulative) VGB dosage was strongly associated with asymptomatic VABAM (p = 0.0028). In an exploratory analysis, we encountered 4 children with symptomatic VABAM among 104 patients with detailed VGB exposure data. Risk of symptomatic VABAM was seemingly dose-independent, and potentially associated with concomitant hormonal therapy (i.e., prednisolone and adrenocorticotropic hormone [ACTH]) (p = 0.039). SIGNIFICANCE: We have demonstrated dose-dependent risk of asymptomatic VABAM and uncovered a possible association between symptomatic VABAM and concomitant hormonal therapy. Caution should be exercised in the use of high VGB dosage (i.e., >175 mg/kg/day), and further study is warranted to confirm the potential impact of hormonal therapy.

A lack of clinically apparent vision loss among patients treated with vigabatrin with infantile spasms: The UCLA experience.

BACKGROUND: Vigabatrin (VGB) is one of two FDA-approved medications for treatment of infantile spasms. Despite demonstrated efficacy, its use has been curtailed by reports indicating a substantial risk of VGB-associated visual field loss (VAVFL). As these reports have conflicted with our clinical observations in routine practice, we systematically reviewed the experiences of patients treated with VGB at UCLA to estimate the prevalence of clinically apparent VAVFL. METHODS: Patients with video-EEG-confirmed infantile spasms evaluated at our center between February 2007 and February 2014 were retrospectively identified. Among patients with VGB exposure, we documented relevant clinical factors and determined the duration of therapy, peak dosage, and cumulative dosage. Based on a review of serial neurologic and ophthalmologic reports and aided by electroretinography (ERG) assessments when available, we ascertained whether each patient had evidence of clinically apparent vision impairment (i.e., recognized by a neurologist or ophthalmologist during any follow-up visit) and whether or not the vision loss was attributed to VGB exposure (i.e., evidence of bilateral, symmetric, and peripheral visual field loss), either by the treating physician or on retrospective review by the study team. RESULTS: During the study period, 257 patients with video-EEG-confirmed infantile spasms were identified. One hundred and forty-three (56%) patients received VGB. Although visual loss of any cause was common among patients with (31%) and without (32%) VGB exposure, there were no cases in which visual field defects were plausibly linked to VGB. We estimate that the risk of clinically significant VAVFL does not exceed 3.2% (95% CI upper bound). Vision loss was never characterized as exclusively peripheral and was always better explained by other causes (e.g., hemianopsia following hemispherectomy and cortical vision impairment after hypoxic ischemic encephalopathy). Precise quantitative exposure data were available for 104 (73%) patients treated with VGB, among whom the median duration of treatment was 8.6 (IQR: 3.7-16.2) months, the median peak dosage was 141.5 (IQR: 104.8-166.0) mg/kg/day, and the median cumulative dosage was 314 (IQR: 140.8-645.7) grams. CONCLUSIONS: We found that the risk of clinically apparent vision loss is quite low among young children treated for infantile spasms. Our estimate of risk contrasts with prior studies and likely reflects our ascertainment of vision loss without the aid of perimetry or serial ERG, the short treatment duration, and the relatively young age of our patients. In the treatment of infantile spasms, risk-benefit assessment should consider both the low prevalence of ERG-identified VAVFL among patients with brief (<6-9months) exposure and the very low prevalence of clinically apparent VAVFL in this population.
