Compliance with preoperative care measures reduces surgical site infection after colorectal operation.

BACKGROUND: Surgical site infections (SSIs) are a major cause of morbidity complicating colorectal operations. Several evidence-based preoperative strategies are associated with decreased SSI rates. We hypothesize that compliance with multiple strategies is associated with lower incidence of SSI after the elective colorectal operation. METHODS: Preoperative care measure compliance before colorectal operations were assessed. Measures included antiseptic wash the night before and day of operation, oral antibiotic, and mechanical bowel preparation, antibiotic prophylaxis, Chloraprep skin preparation, and hair clipping. Rates of SSI after colectomy and other pertinent outcomes were stratified by full and partial compliance with preoperative measures. Exclusion criteria included bowel perforation, ischemia, complete obstruction, intra-abdominal abscess, and no intraoperative skin closure. RESULTS: Eight hundred twenty-six subjects underwent colectomy between 2010 and 2016; 469 met inclusion criteria. Compliance with all measures occurred in 214 (46%) and was independently associated with lower postoperative infection rates (odds ratio [OR], 0.37; confidence interval [CI], 0.16-0.85; P = 0.02). SSI occurred in 51 (11%): was superficial in 35 (7%); deep in 5 (1%); and organ space in 11 (2%). SSI rates were reduced from 16% (partial or no compliance group) to 5% (full compliance group). No stand-alone intervention was independently associated with decreased SSI rate. Multivariate analysis found the following factors associated with a lower risk of SSI: full compliance with all five process measures, lower BMI, nonsmoker, and minimally invasive operation. DISCUSSION AND CONCLUSION: Compliance with preoperative care strategies reduces rates of SSI after colectomy with a cumulative effect more pronounced than any single intervention reinforcing the need for protocol-driven and evidence-based care for patients undergoing colorectal operations.

Using Audience Response Systems for Real-Time Learning Assessments During Surgical Morbidity and Mortality Conference.

OBJECTIVE: Morbidity and mortality (M&M) conference is a mainstay of surgical education. However, its effectiveness is poorly described. The purpose of this study was to demonstrate the feasibility of a real-time audience response system for learner assessment during M&M. DESIGN: We integrated a web-based audience response system into weekly M&M conference. First, this platform collected qualitative responses about the role of M&M. Then, we used the platform to direct questions to attendees in real time. Questions focused on surgical risk estimation and classifying root causes. Responses were grouped by training and compared to a validated risk tool's prediction. Root cause assignment concordance was statistically compared using Cohen's kappa between the pluralities of faculty responses to that of trainees. SETTING: General surgical residency program based at a tertiary academic medical center. PARTICIPANTS: Affiliated categorical residents, preliminary residents, and clinical fellows. RESULTS: We enrolled 110 participants (38 faculty, 31 senior trainees, and 41 trainees). The majority of respondents (75.9%) cited education as the purpose of M&M, and all of respondents stated education as their personal motivation. Audience response questions were integrated into 34 unique case presentations. Mean absolute differences between predicted complication rates and attendees' predictions were highest for faculty (-9.4%, p = 0.009) and lowest for junior residents (-1.8%, p = 0.385). When assigning root cause of each morbidity, concordance between faculty and trainees was low to moderate (K = 0.41). CONCLUSIONS: Assessment of learning during M&M can be performed in real time with discrimination observed by learner experience level. These data support development of this response platform to trend learner performance over time and to monitor targeted educational interventions at future M&Ms.

Intentional ingestions of foreign objects among prisoners: A review.

The intentional ingestion of foreign objects (IIFO) is described more commonly in prison populations than in the general population, with an estimated annual incidence of 1 in 1900 inmates in our state correctional facilities. Incidents often involve ingestion of small metal objects (e.g., paperclips, razor blades) or other commonly available items like pens or eating utensils. Despite ingestion of relatively sharp objects, most episodes can be clinically managed with either observation or endoscopy. Surgery should be reserved for those with signs or symptoms of gastrointestinal perforation or obstruction. For those with a history of IIFO, efforts should focus on prevention of recurrence as subsequent episodes are associated with higher morbidity, significant healthcare and security costs. The pattern of IIFO is often repetitive, with escalation both in frequency of ingestions and in number of items ingested. Little is known about successful prevention strategies, but efforts to monitor patients and provide psychiatric care are potential best-practice strategies. This article aims to provide state-of-the art review on the topic, followed by a set of basic recommendations.

Comorbidity-polypharmacy score predicts in-hospital complications and the need for discharge to extended care facility in older burn patients.

Advancing age is associated with increased mortality despite smaller burn size. Chronic conditions are common in the elderly with resulting polypharmacy. The Comorbidity-Polypharmacy Score (CPS) facilitates quantitative assessment of the severity of comorbid conditions, or physiologic age. Burn injury in older patients is associated with increasing morbidity and mortality and the CPS may be predictive of outcomes such as mortality, ICU and hospital LOS, complications, and final hospital disposition. Our goal was to evaluate the predictive value of CPS for outcomes in the elderly burn population. A retrospective study was undertaken of 920 burn patients with age ≥45 admitted with acute burn injuries (January 1, 2006 to December 31, 2012). CPS was calculated by adding preinjury comorbidities and medications. Subjects were stratified into three groups according to CPS severity. Data collected included demographics, total body surface area burned (TBSA), presence of inhalation injury, ICU/hospital length of stay, complications, discharge disposition, and mortality. Univariate and multivariate analyses were performed. The mean age was 55.7; 72.9% were males; the mean initial TBSA was 6.93%; and mean CPS was 8.01. The risk of in-hospital complications is independently associated with CPS (OR 1.35). CPS (OR 1.81) was an independent predictor of discharge to a facility CPS but not of mortality. While increasing CPS was associated with lower TBSA, mortality remained unchanged. CPS is an independent predictor of in-hospital complications and need for transfer to extended care facilities in older burn patients, which can be determined at the stage of admission to help direct patient management.

A systematic review of the need for MRI for the clearance of cervical spine injury in obtunded blunt trauma patients after normal cervical spine CT.

Clearance of cervical spine injury (CSI) in the obtunded or comatose blunt trauma patient remains controversial. In patients with unreliable physical examination and no evidence of CSI on computed tomography (CT), magnetic resonance imaging of the cervical spine (CS-MRI) is the typical follow-up study. There is a growing body of evidence suggesting that CS-MRI is unnecessary with negative findings on a multi-detector CT (MDCT) scan. This review article systematically analyzes current literature to address the controversies surrounding clearance of CSI in obtunded blunt trauma patients. A literature search through MEDLINE database was conducted using all databases on the National Center for Biotechnology Information (NCBI) website (www.ncbi.nlm.nih.gov) for keywords: "cervical spine injury," "obtunded," and "MRI." The search was limited to studies published within the last 10 years and with populations of patients older than 18 years old. Eleven studies were included in the analysis yielding data on 1535 patients. CS-MRI detected abnormalities in 256 patients (16.6%). The abnormalities reported on CS-MRI resulted in prolonged rigid c-collar immobilization in 74 patients (4.9%). Eleven patients (0.7%) had unstable injury detected on CS-MRI alone that required surgical intervention. In the obtunded blunt trauma patient with unreliable clinical examination and a normal CT scan, there is still a role for CS-MRI in detecting clinically significant injuries when MRI resources are available. However, when a reliable clinical exam reveals intact gross motor function, CS-MRI may be unnecessary.
