Background Rib fracture (RF) pain management provides analgesia while reducing opioids. We postulated: (1) Prescriber factors affect opiate duration, and (2) lidocaine infusion curtails dependency. Materials and Methods Retrospective study of RF patients undergoing multimodal analgesia at ACS-verified Level 1 Trauma Center April 2018-February 2020. Exclusions: ageResults 153 patients included – 113 (74%) stopped opiates by 30 days post-discharge (NORx30), 40 (26%) continued beyond 30 days (Rx+). No significant differences in age, gender, ISS, number of RF, bilaterality, flail chest, and discharge disposition. Significant differences included hospital LOS (7.62 NORx30 vs. 10.22 Rx+, p = .02), number of prescribers (1.73 NORx30 vs. 2.98 Rx+, p < .01), average MME/day during initial 30 days post-discharge (36.7 ± 17 NORx30 vs. 45.4 ± 30.2 Rx+, p = .03), and number of pills (49 ± 38 NORx30 vs. 120 ± 85 Rx+, p < .01). Patients who received lidocaine infusion (LIDO+) had lower MME/day prescribed (32.24 ± 19.9, p = .03), were younger (61.2 vs. 65.6, p < .01), had more RFs (7.1 vs. 6.05, p = .03), and shorter LOS (7.71 vs 10.2, p = .01). Discussion Prescriber attention to MME/day and number of pills dispensed affects opioid dependency. We recommend 35–40 MME/day with 50 pill/month limit prescribed by a single provider monitoring patient and CSMD. Early LI offers post-discharge opioid cessation advantage.

Background Enhanced recovery after surgery (ERAS) protocols are widely utilized for elective colorectal surgery to improve outcomes and decrease costs, but few studies have evaluated the impact of ERAS protocols on cost with respect to anatomic site of resection. This study evaluated the impact of ERAS protocol on elective colon resections by site and longitudinal impact over time. Methods A single-center retrospective cohort study of 598 consecutive patients undergoing elective colorectal resection before and after implementation of ERAS protocol from 2013 to 2017 was performed. The primary outcomes were length of stay (LOS) and cost. Comparative and multivariate inferential statistics were used to assess additional outcomes. Results A total of 598 patients (100 pre-ERAS vs 498 post-ERAS) were evaluated with an overall median LOS of 4 days for right and left colectomies and 3 days for transverse colectomies. When comparing type of resection before and after ERAS protocol introduction, an increased LOS for left hemicolectomies from 3.09 to 4.03 days ( P = .047) was noted, with all other comparisons failing to reach statistical significance. Over time, an initial decrease in LOS for MIS approach after protocol introduction was observed; however, this effect diminished in the ensuing years and had no significant effect overall. Total cost of care was significantly increased post-ERAS for all cohorts except transverse colectomies. No further statistically significant differences were found. Conclusion After an initial improvement in outcomes, continued utilization of ERAS protocols demonstrated no improvement in LOS compared to pre-ERAS data and increased cost overall for patients regardless of site of resection.

Our hospital, a Tennessee Surgical Quality Collaborative (TSQC) member, adopted a statewide colorectal care bundle intended to reduce surgical site infections (SSI) in elective colorectal cases. The bundle includes proper antibiotics/dosing, normoglycemia, normothermia, supplemental oxygen six hours postoperatively, and early enteral nutrition. A single-institution retrospective study of our National Surgical Quality Improvement Program (NSQIP) database for the rates of SSI before and after the colorectal bundle. We compared our SSI rates to TSQC hospitals as well as NSQIP datasets. Because of low case numbers in the NSQIP data, National Healthcare Safety Network (NHSN) data collected at our institution was used to compare our colorectal SSI before and after our colorectal bundle. From January 2010 to December 2011, 188 patients underwent nonemergent colorectal surgery in the NSQIP data. Of these, 5.4 per cent (10/188) developed superficial SSIs. During this same time, the rate of the TSQC superficial SSI was 7.1 per cent and NSQIP was 7.8 per cent. From January 2013 to October 2014, after the colorectal bundle started, 76 patients in NSQIP underwent nonemergent colorectal surgery. Of these, 6.5 per cent (5/76) developed superficial SSI, compared with 5.5 per cent in TSQC and 5.5 per cent in NSQIP. NHSN data showed a prebundle rate of 11 per cent and a postbundle rate of 3.5 per cent ( P < 00.1, χ2). After adopting a colorectal bundle aimed at reducing SSIs, we did not improve our SSI rates in NSQIP; however, our NHSN data demonstrated considerable improvement. Differences in data collection may affect SSI rates, and ultimately “quality” based reimbursement. Implementation of the bundle did improve outcomes in colorectal surgery.

Minimally invasive surgery has found many applications in general surgery. The role of laparoscopy in trauma has been debated as a diagnostic, as well as therapeutic, tool in hemodynamically stable patients. This study evaluated laparoscopy in the trauma population. A retrospective review of all laparoscopies performed in hemodynamically stable trauma patients from 1996 until 2006 was conducted. Mechanisms of injury, perioperative data, and demographic variables were analyzed using descriptive statistics and Student's t test. Exploratory diagnostic laparoscopy was performed on 102 patients. Laparoscopy was negative for 65 per cent of patients; 12 per cent of these were converted to laparotomy due to adhesions, hemoperitoneum, or surgeon preference. None of the conversions revealed intra-abdominal injury at laparotomy. An injury was diagnosed at laparoscopy in the remaining 35 per cent, with 55 per cent conversion rate to repair the injury. Therapeutic laparoscopy included serosal repair, hemorrhage control, diaphragmatic repair, and other standard laparoscopic treatments. No patient required re-exploration, there were no missed injuries or other complications, and no patient died in this study. Laparoscopy has an important diagnostic and therapeutic role in selected hemodynamically stable trauma patients. Using a minimally invasive approach can reduce the potential morbidity of negative laparotomy.

Tamoxifen is an antiestrogen used in the treatment of estrogen receptor-positive breast cancer in postmenopausal women. It functions by competitively inhibiting the estrogen receptor and inducing apoptosis and G1 cell cycle arrest. Genistein is a soy phytoestrogen that inhibits breast cancer cell growth in vitro at doses of 10 μM or above. At lower doses genistein may stimulate cell growth and entry into the cell cycle. We hypothesized that treatment with low-dose genistein would reverse the inhibitory effects of tamoxifen in estrogen-receptor-positive breast cancer cells. Cell cycle kinetics and cell proliferation in T47-D human breast cancer cells were examined after exposure to genistein and tamoxifen in a low-estrogen environment designed to mimic a postmenopausal state. Cell proliferation was assessed by a colorimetric assay. Cell cycle kinetics were determined by flow cytometry. Tamoxifen caused G1 arrest and a decrease in proliferation. Genistein reversed the inhibitory effects of tamoxifen on both proliferation and G1 arrest. Thus low-dose genistein was able to inhibit the therapeutic effects of tamoxifen in this postmenopausal model of breast cancer.

The frequency of computed tomography (CT) ordered by emergency department physicians at our facility was noted to sharply increase in early 1998 after a New England Journal of Medicine (NEJM) article recommending routine CT in patients with suspected appendicitis. Numerous studies have proven the accuracy of CT for detecting acute appendicitis; however, the most appropriate use of CT continues to evolve. We sought to evaluate the effect of increased CT use on negative appendectomy rate and perforation rate at our institution and to better delineate in whom CT is most beneficial. CT use was retrospectively evaluated and found to sharply increase in April 1998. The authors then reviewed the medical records of 291 consecutive patients undergoing appendectomy 18 months before and after the NEJM article. Patients with interval appendectomies and those 12 years of age or younger were excluded. The remaining 226 patients constitute the study cohort. The study cohort was then divided into the two groups. The “Discriminate Group” consists of patients from the 18 months before the NEJM article impact and a period of selective CT use. The “Indiscriminate Group” comprises patients from the subsequent 18 months in which CT use was substantially higher and routinely obtained before surgical evaluation. After chart review an objective clinical score (Alvarado score) was assigned to each patient. Comparison was then made between the two groups on perforation rate, negative appendectomy rate, time delay to operating room, and Alvarado score. Additionally patients undergoing preoperative CT were compared with those without CT. These groups were also evaluated on the basis of negative appendectomy rate, perforation rate, and delay to the operating room. CT in patients with abdominal symptoms associated with appendicitis increased from 188 in the Discriminate Group to 1035 in the Indiscriminate Group. In the Discriminate Group the negative appendectomy rate was 15.1 per cent. After the indiscriminate use of CT the negative appendectomy rate decreased to 13.3 per cent, but this was not significant. Males experienced a decrease in the negative appendectomy rate from 10.1 to 6.9 per cent, whereas the rate for females increased slightly from 21.3 to 22.9 per cent. Again we found no statistical significance in these changes. The overall perforation rate of 17.9 per cent in the first 18 months decreased to 13.3 per cent in the following 18 months but again was not statistically significant. The Alvarado scores between the Discriminate and Indiscriminate groups were 6.7 and 7.3, respectively ( P = 0.02). Patients with preoperative CT averaged 11.9 hours to the operating room compared with 6.5 hours for those without CT ( P = 0.03). Use of CT did not decrease perforation rate but did globally reduce negative exploration ( P = 0.05). This reduction in negative exploration however was not discriminated by sex. CT use in suspected acute appendicitis has greatly increased over the past several years. The dramatic increase in CT use at our institution has not resulted in dramatic decreases in negative appendectomy rate or statistically significant changes in perforation rate. The optimal use of CT in evaluating patients with suspected appendicitis has yet to be determined. Surgical consultation should be obtained early to avoid indiscriminate tests.

We assessed the effect of blood alcohol concentration (BAC) on the evaluation, outcome, and hospital charges of our observation-status trauma patient population. We conducted a retrospective study over 18 months; any patient initially admitted with 80 mg/dL; BAC- =
