Cost-effective and rapid methods for screening are highly desirable for mutation scanning, particularly in clinical settings, where eligibility is partly dictated by cost of testing.
A formal evaluation of ACASI as a screening tool to determine eligibility in settings as ours is justified, as planned intervention studies will include Pre-Exposure Prophylaxis that may be especially appealing to prospective volunteers to overstate their sexual risk behaviour and ensure enrolment.
In particular, the 2 day window of stable or decreasing ventilator settings prior to VAC eligibility might need to be lengthened to avoid mislabeling patients who require staggered increases in ventilator support when intubated for respiratory failure from a disease that continues to progress after intubation.
The questions define the populations, exposures, comparators, outcomes, timings, and settings of interest (PECOTS) eligibility criteria for the evaluation (e.g., see discussion in AHRQ 2013).
5 In 2010, WHO issued guidance to resource-constrained settings to expand the eligibility of the treated population, by recommending initiation of ART when a patient's CD4 T-cell count reached 350/μL or less, or was clinically necessitated.
Definitions of retention in HIV care prior to ART eligibility varied across settings and healthcare systems, thus making the comparison between studies challenging.
Studies differed in their design, eligibility criteria, study settings and sample size, as well as in the clinical characteristics of their study populations (symptomatic and asymptomatic), classification of malnutrition and reference growth standards used for interpretation of anthropometric indicators.
Each program determines provider eligibility, payment amount, and permissible settings for administration.
The thresholds for stability prior to VAC eligibility, minimum changes in ventilator settings, and duration of changes merit further evaluation.
For example, item 4 addresses eligibility of participants and the settings and locations of data collection.
