The validity of basing healthcare reimbursement policy on pay-for-performance is grounded in the accuracy of performance measurement. ⋯ Nonhierarchical modeling frequently misclassified average-quality hospitals as low quality. Hierarchical modeling commonly misclassified low-quality hospitals as average. Assuming that the consequences of misclassifying an average-quality hospital as low quality outweigh the consequences of misclassifying a low-quality hospital as average, hierarchical modeling may be the better choice for quality measurement.

New Setting of Neurally Adjusted Ventilatory Assist during Noninvasive Ventilation through a Helmet.
Compared to pneumatically controlled pressure support (PSP), neurally adjusted ventilatory assist (NAVA) was proved to improve patient-ventilator interactions, while not affecting comfort, diaphragm electrical activity (EAdi), and arterial blood gases (ABGs). This study compares neurally controlled pressure support (PSN) with PSP and NAVA, delivered through two different helmets, in hypoxemic patients receiving noninvasive ventilation for prevention of extubation failure. ⋯ When delivering noninvasive ventilation by helmet, compared to PSP and NAVA, PSN improves comfort and patient-ventilator interactions, while not ABGs.
