Where do we go from here? A small scale observation of transfer results from chronic to skilled ventilator facilities.
Skilled nursing facility ventilator units (SNF) are a recent attempt to reduce the costs of an increasing number of patients who are in acute intensive care units and are not able to be liberated from ventilators. Transfers of such patients from long-term care chronic vent units (LTCVs) to SNFs in Maryland began in 2006. The safety of these transfers needs to be assessed. ⋯ We recognize that bias may occur in patients choosing to remain in our LTCV compared to those accepting transfers, the magnitude of the difference in mortality indicates the need for more comprehensive well designed analysis investigating the outcome of all transfers occurring to and from LTCVs.

COPD is characterized by chronic airway inflammation and remodeling, with serious modifications of the extracellular matrix (ECM). Hyaluronic acid (HA) is an abundant ECM molecule in the lung with various biologic functions that depend on its molecular weight (MW). High-MW HA exhibits antiinflammatory and immunosuppressive effects, whereas low-MW HA is proinflammatory. In this study, we investigated whether acute exacerbations of COPD (AECOPDs), which affect patient quality of life and survival, are associated with altered HA turnover in BAL. ⋯ AECOPDs are associated with increased HYAL activity in BAL and subsequent degradation of HA, which may contribute to airway inflammation and subsequent lung function decline during exacerbations.
