Although therapeutic treatments are intended to help alleviate symptoms associated with disease, safety must be carefully considered and monitored to confirm continued positive benefit/risk balance. The objective of MOBILITY was to study the long-term safety of onabotulinumtoxinA for treatment of various therapeutic indications.

A prospective, multicenter, observational, Phase IV Canadian study in patients treated with onabotulinumtoxinA for a therapeutic indication. Dosing was determined by the participating physician. Adverse events (AEs) were recorded throughout the study.

Patients (n = 1372) with adult focal spasticity, blepharospasm, cerebral palsy, cervical dystonia, hemifacial spasm, hyperhidrosis, or “other” diagnoses were enrolled into the safety cohort. Eighty-three patients (6%) reported 209 AEs; 44 AEs in 24 patients (2%) were considered treatment-related AEs. Seventy-two serious AEs were reported by 38 patients (3%); 10 serious AEs in 5 patients (0.4%) were considered treatment related. Most commonly reported treatment-related AEs were muscular weakness (n = 7/44) and dysphagia (n = 6/44).

In patients with follow-up for up to six treatments with onabotulinumtoxinA, treatment-related AEs were reported in <2% of the safety population over the course of nearly 5 years. Our findings from MOBILITY provide further evidence that onabotulinumtoxinA treatment is safe for long-term use across a variety of therapeutic indications.

Oral anticoagulation (OAC) reduces stroke risk in patients with atrial fibrillation (AF) or atrial flutter (AFL). However, OAC initiation rates in patients discharged directly from the emergency department (ED) are low. We aimed to address this care gap by implementing a quality improvement intervention.

The study was performed in four Canadian urban EDs between 2015 and 2016. Patients were included if they had an electrocardiogram (ECG) documenting AF/AFL in the ED, were directly discharged from the ED, and were alive after 90 days. Baseline rates of OAC initiation were determined prior to the intervention. Between June and December 2016, we implemented our intervention in two EDs (ED-intervention), with the remaining sites acting as controls (ED-control). The intervention included a reminder statement prompting OAC initiation according to guideline recommendations, manually added to ECGs with a preliminary interpretation of AF/AFL, along with a decision-support algorithm that included a referral sheet. The primary outcome was the rate of OAC initiation within 90 days of the ED visit.

Prior to the intervention, 37.2% OAC-naïve patients with ECG-documented AF/AFL were initiated on OAC. Following implementation of the intervention, the rate of OAC initiation increased from 38.6% to 47.5% (absolute increase of 8.5%; 95% CI, 0.3% to 16.7%, p=0.04) among the ED-intervention sites, whereas the rate remained unchanged in ED-control sites (35.3% to 35.9%, p=0.9).

Implementation of a quality improvement intervention consisting of a reminder and decision-support tool increased initiation of OAC in high-risk patients. This support package can be readily implemented in other jurisdictions to improve OAC rates for AF/AFL.

Apathy is a very common behavioural and psychological symptom across brain disorders. In the last decade, there have been considerable advances in research on apathy and motivation. It is thus important to revise the apathy diagnostic criteria published in 2009. The main objectives were to: a) revise the definition of apathy; b) update the list of apathy dimensions; c) operationalise the diagnostic criteria; and d) suggest appropriate assessment tools including new technologies.

The expert panel (N = 23) included researchers and health care professionals working on brain disorders and apathy, a representative of a regulatory body, and a representative of the pharmaceutical industry. The revised diagnostic criteria for apathy were developed in a two-step process. First, following the standard Delphi methodology, the experts were asked to answer questions via web-survey in two rounds. Second, all the collected information was discussed on the occasion of the 26th European Congress of Psychiatry held in Nice (France).

Apathy was defined as a quantitative reduction of goal-directed activity in comparison to the patient’s previous level of functioning (criterion A). Symptoms must persist for at least four weeks, and affect at least two of the three apathy dimensions (behaviour/cognition; emotion; social interaction; criterion B). Apathy should cause identifiable functional impairments (criterion C), and should not be fully explained by other factors, such as effects of a substance or major changes in the patient’s environment (Criterion D).

The new diagnostic criteria for apathy provide a clinical and scientific framework to increase the validity of apathy as a clinical construct. This should also help to pave the path for apathy in brain disorders to be an interventional target.
