Improving physician documentation for malnutrition: A sustainable quality improvement initiative.

This study compares documentation and reimbursement rates before and after provider education in nutritional status documentation. Our study aimed to evaluate accurate documentation of nutrition status between registered dietitian nutritionists and licensed independent practitioners before and after the implementation of a dietitian-led Nutrition-Focused Physical Exam intervention at an academic medical center in the southeastern US. ICD-10 codes identified patients from 10/1/2016-1/31/2018 with malnutrition. The percentage of patients with an appropriate diagnosis of malnutrition and reimbursement outcomes attributed to malnutrition documentation were calculated up to 24 months post-intervention. 528 patients were analyzed. Pre-intervention, 8.64% of patients had accurate documentation compared to 46.3% post-intervention. Post-intervention, 68 encounters coded for malnutrition resulted in an estimated $571,281 of additional reimbursement, sustained at 6, 12, 18, and 24 months. A multidisciplinary intervention improved physician documentation accuracy of malnutrition status and increased reimbursement rates.

Obesity and laparoscopic colectomy: outcomes from the ACS-NSQIP database.

BACKGROUND: Previous reports comparing outcomes of laparoscopic colectomy in obese vs nonobese patients from small, single-institution series have included few obese patients and have shown variable results, some suggesting that obesity has no impact on outcomes. OBJECTIVE: We aimed to determine whether any intraoperative or short-term postoperative outcome of laparoscopic colectomy is affected by obesity, independent of other variables. DESIGN: We performed a retrospective study comparing outcomes of patients undergoing laparoscopic colectomy grouped by BMI. PATIENTS: We queried American College of Surgeons National Surgical Quality Improvement Program Participant Use Data Files for patients undergoing nonemergent, laparoscopic colectomy from 2005 through 2008. Cases with a secondary procedure (with the exception of laparoscopic lysis of adhesions, rigid proctosigmoidoscopy, or laparoscopic splenic flexure takedown) were excluded. MAIN OUTCOME MEASURES: We analyzed operative time, length of stay, transfusion requirement, reoperation within 30 days, wound complications, pulmonary complications, sepsis/septic shock, deep venous thrombosis, renal failure/insufficiency, and death. We tested for differences in outcomes using χ tests or analyses of variance, and when differences between BMI classes were found, we performed multivariable regression to adjust for preoperative and intraoperative variables. RESULTS: In an analysis of 9693 patients (30% with BMI ≥30), significant differences were found among BMI classes for length of stay, operative time, and wound complication. Operative time correlated with BMI class independent of other variables; length of stay did not. After adjustment of all available variables, obesity remained an independent risk factor for wound complication, and the odds ratios increased with increasing obesity class. LIMITATIONS: Retrospective design and standardized outcome measures prevent examination of procedure-specific outcomes; therefore, this is not an intention-to-treat analysis. CONCLUSIONS: These data confirm that, in patients undergoing laparoscopic colectomy, obesity is an independent risk factor for wound complications. Although obesity also increases operative time, the effect of obesity on wound complications remains after adjustment for this and other risk factors.

Novel Technique to Reduce the Incidence of SSI after Colorectal Surgery.

SSI is a leading cause of morbidity and increases health-care cost after colorectal operations. It is a key hospital-level patient safety indicator. Previous literature has identified perioperative risk factors associated with SSI and interventions to decrease rate of infection. The purpose of this study was to evaluate the impact of blowhole closure on the rate of superficial and deep SSI. The ACS-NSQIP database was queried for patients undergoing colectomy at the University of Kentucky from 2013 to 2016. Retrospective chart review was performed to gather demographic data and perioperative variables. Wounds left open and packed were excluded. Rates of postoperative SSI were measured between the groups. One thousand eighty-three patients undergoing elective and emergent colectomy were reviewed. Nine hundred and forty-five had closed incision and 138 had blowhole closure. Patient characteristics between the groups were well matched. Patients with a blowhole closure were more likely to have an open procedure (P = 0.037) and a higher wound class (P < 0.001). The rate of superficial and deep SSI was 9.1 per cent in patients with a closed incision and 5.1 per cent in patients with blowhole closure (P = 0.142). With adjustment for approach and wound class, blowhole closure decreased the incidence of SSI (P = 0.04). There was no significant difference in morbidity or mortality. Patients undergoing elective and emergent colectomy had decreased incidence of SSI when blowhole closure was used. Given that it does not increase resource usage and its technical ease, blowhole closure should become the standard method of surgical wound closure.

Surgeon-administered conscious sedation and local anesthesia for ambulatory anorectal surgery.

Anorectal procedures are often performed in an outpatient setting using a variety of anesthetic techniques. One technique that has not been well studied is surgeon-administered conscious sedation along with local anesthetic. The purpose of this study was to evaluate the use of this technique with emphasis on safety, efficacy, and patient satisfaction. Chart review was performed on 133 consecutive patients who had anorectal procedures at an outpatient surgery center. Additionally, 65 patients were enrolled prospectively and completed a satisfaction survey. Inclusively, charts of 198 patients who underwent outpatient anorectal surgery under conscious sedation and local anesthesia under the direction of a colorectal surgeon from 2004 through 2008 were reviewed. Parameters related to patient and procedural characteristics, safety, efficacy, and satisfaction were evaluated. Surgeon-administered sedation consisted of combined fentanyl and midazolam in 90 per cent. Eighty per cent of procedures were performed in the prone position and 23 per cent were in combination with an endoscopic procedure. Eighty-two per cent were classified as American Society of Anesthesiologists Grade 1 or 2. Transient mild hypoxemia or hypotension occurred in 4 and 3 per cent of the patients, respectively. Mean operative time was 29 minutes with a mean stay in the postanesthesia care unit of 37 minutes. There were no early major cardiac or respiratory complications. Ninety-seven per cent of the patients surveyed reported a high degree of satisfaction. Surgeon-administered conscious sedation with local anesthesia was well tolerated for outpatient anorectal surgeries. Additional studies are needed to confirm the safety and efficacy of this technique.

Abdominal versus perineal approach for treatment of rectal prolapse: comparable safety in a propensity-matched cohort.

Abdominal operations for rectal prolapse are associated with lower recurrence rates than perineal procedures but presumed higher morbidity. Therefore, perineal procedures are recommended for patients deemed unfit for abdominal repair. Consequently, bias confounds retrospective comparisons of the two approaches. To clarify the impact of operative approach on outcomes, we analyzed abdominal and perineal procedures in a propensity score-matched analysis. We selected patients undergoing surgery for rectal prolapse from the American College of Surgeons National Surgical Quality Improvement Program data set from 2005 to 2010. We grouped procedures as abdominal or perineal. We identified preoperative variables predictive of complications and regressed against operative approach. The resulting propensity score was used to select a matched cohort with similar clinical risk. We identified 2188 patients (848 abdominal [38.8%]; 1340 perineal [61.2%]). Patients undergoing the perineal approach had higher rates of most risk variables. Propensity matching resulted in 563 matched pairs (1126 patients) with similar clinical risk. In this matched cohort, no significant difference was found in the rate of any complication between the operative approaches; mortality was 0.9 per cent in each group (P = 1.0). Relative risk for major morbidity after abdominal approach was 1.39 (95% confidence interval, 0.92 to 2.10; P = 0.15). Although many patients with rectal prolapse are high risk for abdominal surgery, our study indicates that many patients treated by perineal repair could be safely treated with a more durable operation.

Human rRNA gene clusters are recombinational hotspots in cancer.

The gene that produces the precursor RNA transcript to the three largest structural rRNA molecules (rDNA) is present in multiple copies and organized into gene clusters. The 10 human rDNA clusters represent <0.5% of the diploid human genome but are critically important for cellular viability. Individual genes within rDNA clusters possess very high levels of sequence identity with respect to each other and are present in high local concentration, making them ideal substrates for genomic rearrangement driven by dysregulated homologous recombination. We recently developed a sensitive physical assay capable of detecting recombination-mediated genomic restructuring in the rDNA by monitoring changes in lengths of the individual clusters. To prove that this dysregulated recombination is a potential driving force of genomic instability in human cancer, we assayed the rDNA for structural rearrangements in prospectively recruited adult patients with either lung or colorectal cancer, and pediatric patients with leukemia. We find that over half of the adult solid tumors show detectable rDNA rearrangements relative to either surrounding nontumor tissue or normal peripheral blood. In contrast, we find a greatly reduced frequency of rDNA alterations in pediatric leukemia. This finding makes rDNA restructuring one of the most common chromosomal alterations in adult solid tumors, illustrates the dynamic plasticity of the human genome, and may prove to have either prognostic or predictive value in disease progression.

Congenital bronchobiliary fistula: MRI appearance.

Congenital bronchobiliary fistula (CBBF) is a rare anomaly. Twenty-three cases have been reported since the anomaly was first described in 1952. Most of these cases were diagnosed by bronchoscopy, cholangiography, or hepatobiliary nuclear imaging. Our case of a newborn with bilious emesis with CBBF was depicted by T1-weighted gradient-echo MRI sequences.
