AbstractEarly reports of late outcomes among survivors of ARDS indicated that most patients improved dramatically after their intensive care unit stay, and few lived with residua of their once-severe pulmonary injury. Over the last decade, a collection of new studies with improved methodology and novel questions has improved our understanding of life after ARDS. After reviewing these newer investigations in the context of previously published literature, we have drawn several preliminary conclusions: (1) Long-term survival after hospital discharge is unaffected by ARDS, but is strongly affected by ARDS risk factor and comorbidities. (2) Respiratory symptoms after ARDS are more prevalent than previously indicated, but improve over the first 12 months of recovery. (3) Pulmonary function testing reveals marked impairment soon after ARDS. There is improvement over the first 6 months, with lingering mild decreases in lung volume and diffusing capacity in most patients. A small group of patients have severe impairment without improvement. (4) Quality of life, functional independence, and cognitive function are severely affected by ARDS, with dramatic improvement over the first year. Quality of life is lower than in matched critically ill controls. (5) Significant numbers of ARDS survivors suffer from posttraumatic stress syndrome. This is an exciting time for research in long-term outcomes of ARDS, with potential for future studies that validate these single-center hypotheses, explore their ramifications, and investigate the impacts of changing practices in the intensive care unit in the acute phase of ARDS.
