The current literature suggests deficiencies in the quality of acute pain management among general medical inpatients. The aim of this qualitative study is to identify potential barriers to high-quality acute pain management among general medical inpatients at an urban academic medical center during a 2-year period. Data are collected using retrospective chart reviews, survey questionnaires, and semistructured, open-ended interviews of 40 general medical inpatients who have experienced pain during their hospitalization. Our results confirm high prevalence and disabling impacts of pain and significant patient- and provider-related barriers to high-quality acute pain management. We also identify unique system-related barriers such as time delay and pain management culture. Efforts to improve the pain management experience of general medical inpatients will need to address all these barriers.
