ReviewMagnetic Resonance-Guided Focused Ultrasound Neurosurgery for Essential Tremor: A Health Technology Assessment.
The standard treatment option for medication-refractory essential tremor is invasive neurosurgery. A new, noninvasive alternative is magnetic resonance-guided focused ultrasound (MRgFUS) neurosurgery. We aimed to determine the effectiveness, safety, and cost-effectiveness of MRgFUS neurosurgery for the treatment of moderate to severe, medication-refractory essential tremor in Ontario. We also spoke with people with essential tremor to gain an understanding of their experiences and thoughts regarding treatment options, including MRgFUS neurosurgery. ⋯ MRgFUS neurosurgery is an effective and generally safe treatment option for moderate to severe, medication-refractory essential tremor. It provides a treatment option for people ineligible for invasive neurosurgery and offers a noninvasive option for all people considering neurosurgery.For people ineligible for invasive neurosurgery, MRgFUS neurosurgery is cost-effective compared with no surgery. In people eligible for invasive neurosurgery, MRgFUS neurosurgery may be one of several reasonable options. Publicly funding MRgFUS neurosurgery for the treatment of moderate to severe, medication-refractory essential tremor in Ontario at the current case load would have a net budget impact of about $1 million per year for the next 5 years.People with essential tremor who had undergone MRgFUS neurosurgery reported positive experiences. They liked that it was a noninvasive procedure and reported a substantial reduction in tremor that resulted in an improvement in their quality of life.

ReviewPsychotherapy for Major Depressive Disorder and Generalized Anxiety Disorder: A Health Technology Assessment.
Major depressive disorder and generalized anxiety disorder are among the most commonly diagnosed mental illnesses in Canada; both are associated with a high societal and economic burden. Treatment for major depressive disorder and generalized anxiety disorder consists of pharmacological and psychological interventions. Three commonly used psychological interventions are cognitive behavioural therapy (CBT), interpersonal therapy, and supportive therapy. The objectives of this report were to assess the effectiveness and safety of these types of therapy for the treatment of adults with major depressive disorder and/or generalized anxiety disorder, to assess the cost-effectiveness of structured psychotherapy (CBT or interpersonal therapy), to calculate the budget impact of publicly funding structured psychotherapy, and to gain a greater understanding of the experiences of people with major depressive disorder and/or generalized anxiety disorder. ⋯ Compared with usual care, treatment with CBT, interpersonal therapy, or supportive therapy significantly reduces depression symptoms posttreatment. CBT significantly reduces anxiety symptoms posttreatment in patients with generalized anxiety disorder.Compared with usual care, treatment with structured psychotherapy (CBT or interpersonal therapy) represents good value for money for adults with major depressive disorder and/or generalized anxiety disorder. The most affordable option is group structured psychotherapy provided by nonphysicians, with the selective use of individual structured psychotherapy provided by nonphysicians or physicians for those who would benefit most from it (i.e., patients who are not engaging well with or adhering to group therapy).

Review Comparative StudyLong-Term Continuous Ambulatory ECG Monitors and External Cardiac Loop Recorders for Cardiac Arrhythmia: A Health Technology Assessment.
Ambulatory electrocardiography (ECG) monitors are often used to detect cardiac arrhythmia. For patients with symptoms, an external cardiac loop recorder will often be recommended. The improved recording capacity of newer Holter monitors and similar devices, collectively known as longterm continuous ambulatory ECG monitors, suggests that they will perform just as well as, or better than, external loop recorders. This health technology assessment aimed to evaluate the effectiveness, cost-effectiveness, and budget impact of longterm continuous ECG monitors compared with external loop recorders in detecting symptoms of cardiac arrhythmia. ⋯ Although both longterm continuous ambulatory ECG monitors and external cardiac loop recorders were more effective than a 24-hour Holter monitor in detecting symptoms of cardiac arrhythmia, we found no evidence to suggest that these two devices differ in effectiveness. Assuming that the use of longterm continuous monitors will continue to increase in the next 5 years, the public health care system in Ontario can expect to see added costs of $130,000 to $370,000 per year.

ReviewPatient Safety Learning Systems: A Systematic Review and Qualitative Synthesis.
A patient safety learning system (sometimes called a critical incident reporting system) refers to structured reporting, collation, and analysis of critical incidents. To inform a provincial working group's recommendations for an Ontario Patient Safety Event Learning System, a systematic review was undertaken to determine design features that would optimize its adoption into the health care system and would inform implementation strategies. ⋯ The design of a patient safety learning system can be optimized by an awareness of the barriers to and facilitators of successful adoption and implementation identified by health care professionals. Evaluation of the effectiveness of a patient safety learning system is needed to refine its design.
