Opioid Prescribing Behaviors Among Surgical Intensive Care Unit Attending Physicians

More than 5 million Americans misuse opioids. Six percent of patients who receive opioids for acute pain progress to chronic use; this increases with higher doses and longer prescriptions. Prescribing variation exists within trauma centers and after emergency surgery but has not been demonstrated among intensivists.

Milligram morphine equivalents (MME) per patient-ICU-day provided by eleven surgical intensivists were analyzed. The patients were separated into 2 groups based on their percentage of time intubated in the surgical ICU. Both study groups were compared using demographics and comorbidity scores. The attendings were divided into high- and low-prescribing groups based on their MME/pt-ICU-day for intubated patients, and bivariate statistical analyses were performed. A similar analysis compared surgery vs anesthesia intensivists.

The analysis included 257 patients in the "long-vent group" (LVG) and 668 patients in the "short-vent group" (SVG). The average MME/pt-ICU-day for the LVG was 222. Despite no significant differences in age, sex, or Elixhauser Comorbidity Index, there was a 45% difference between the high- and low-prescribing physicians in the LVG (253.7 vs 175.4 MME/pt-ICU-day; P = .008). This difference was not observed for patients in the SVG (74.3 vs 93.1 MME/pt-ICU-day; P = .141) nor based on intensivist specialty (LVG: 217.9 vs 209.5 MME/pt-ICU-day; P = .8) (SVG: 79.0 vs 93.3 MME/pt-ICU-day; P = .288).
