RESUMEN
OBJECTIVE: The aim of this study was to determine whether an educational intervention was sufficient to decrease opioid prescribing after general surgical operations. SUMMARY OF BACKGROUND DATA: We recently analyzed opioid prescription and use for 5 common outpatient operations at our institution: partial mastectomy (PM), PM with sentinel lymph node biopsy (PM SLNB), laparoscopic cholecystectomy (LC), laparoscopic inguinal hernia repair (LIH), and open inguinal hernia repair (IH). We found that opioids were over-prescribed. We formulated guidelines for opioid prescribing that would halve the number of pills prescribed and also satisfy 80% of patients' opioid requirements. METHODS: We discussed our findings and opioid-prescribing guidelines with surgeons at our institution. We recommended that surgeons encourage patients to use a nonsteroidal anti-inflammatory drug (NSAID) and acetaminophen before using opioids. We then evaluated opioid prescriptions and use in 246 subsequent patients undergoing these same operations. RESULTS: The mean number of opioid pills prescribed for each operation markedly decreased: PM 19.8 versus 5.1; PM SLNB 23.7 versus 9.6; LC 35.2 versus 19.4; LIH 33.8 versus 19.3, and IH 33.2 versus 18.3; all P < 0.0003. The total number of pills prescribed decreased by 53% when compared with the number that would have been prescribed before the educational intervention. Only 1 patient (0.4%) required a refill opioid prescription. Eighty-five percent of patients used either a NSAID or acetaminophen. CONCLUSIONS: By defining postoperative opioid requirements through patient surveys and disseminating operation-specific guidelines for opioid prescribing to surgeons, we were able to decrease the number of opioids initially prescribed by more than half. Decreased initial opioid prescriptions did not result in increased opioid refill prescriptions.

PURPOSE: The effect of pre-operative MRI on the in-breast tumor recurrence rate (IBTR) of patients undergoing breast-conservation treatment (BCT) remains uncertain. We began to routinely perform pre-operative MRI in 2006. Our goal was to determine the effect of pre-operative MRI on IBTR. METHODS: Retrospective review of a prospective database of all patients undergoing BCT (n = 1396) from 2000 to 2010. IBTR were calculated using Kaplan-Meier estimates. RESULTS: 664 (47.6%) patients underwent pre-operative MRI. The use of MRI increased from 13.9% in 2000-2005 to 80.7% in 2006-2010. Ten percent of patients who underwent MRI were found to have an additional ipsilateral cancer, with a mean diameter of 1.6 cm. The IBTR for patients with and without MRI were 4% vs. 8% at 8 years (p = 0.04). In multivariate analysis, radiation therapy and endocrine therapy were associated with decreased IBTR, but MRI was not (RR 0.77 (0.45-1.28)). For 1030 patients with invasive cancer, the IBTR at 8 years with and without MRI was 4.2% vs. 7.3% (p = 0.28). For 366 DCIS patients with and without MRI, the IBTR was 3.6% vs. 10.9% (p = 0.06). In the subgroup of DCIS patients who did not receive radiation, the IBTR with and without MRI was 0% vs. 18.2% (p = 0.08). Patients with an additional cancer found by MRI had a higher IBTR at 8 years (10.1% vs. 3.3%, p = 0.02). CONCLUSIONS: In a study analyzing BCT patients from one time period who rarely had a pre-operative MRI and a subsequent time period where most patients had MRI, the use of MRI was associated with a decrease in the IBTR on univariate, but not multivariate analysis. Patients who had additional cancers detected had a significantly higher IBTR.
