Do health plans influence quality of care?
There are activities that plans can undertake which influence their HEDIS scores. On the face of it, these results suggest that plans can independently improve quality, in contrast to hypotheses that plans would be "too far" from patients to have an influence. Continued attention to collecting plan-level data is warranted. Further work should address other possible sources of variations in HEDIS scores, such as variability in the quality of plan administrative databases.
These data demonstrate that the potential pulmonary risk of repeated lung stretch during volume recruitment is significantly less than the damage arising from the avoidance of such maneuvers in lungs in which alveolar recruitment is possible. We conclude that sustained inflations during high-frequency oscillatory ventilation produce the benefits of increased oxygenation for a given mean airway pressure plus decreased progression of lung injury.
