Implementing Inpatient Social Needs Screening in an Urban Tertiary Care Children's Hospital.

BACKGROUND AND OBJECTIVES: The American Academy of Pediatrics recommends screening for unmet social needs, and the literature on inpatient screening implementation is growing. Our aim was to use quality improvement methods to implement standardized social needs screening in hospitalized pediatric patients. METHODS: We implemented inpatient social needs screening using the Model for Improvement. An interprofessional team trialed interventions in a cyclical manner using plan-do-study-act cycles. Interventions included a structured screening questionnaire, standardized screening and referrals workflows, electronic health record (EHR) modifications, and house staff education, deliberate practice, and feedback. The primary outcome measure was the percentage of discharged patients screened for social needs. Screening for social needs was defined as a completed EHR screening questionnaire or a full social work evaluation. Process and balancing measures were collected to capture data on screening questionnaire completion and social work consultations. Data were plotted on statistical process control charts and analyzed for special cause variation. RESULTS: The mean monthly percentage of patients screened for social needs improved from 20% at baseline to 51% during the intervention period. Special cause variation was observed for the percentage of patients with completed social needs screening, EHR-documented screening questionnaires, and social work consults. CONCLUSIONS: Social needs screening during pediatric hospitalization can be implemented by using quality improvement methods. The next steps should be focused on sustainability and the spread of screening. Interventions with greater involvement of interdisciplinary health care team members will foster process sustainability and allow for the spread of screening interventions to the wider hospitalized pediatric population.

Children With Chronic Health Conditions and Social Needs: Investigating Outcomes to Drive Health System Improvements.

Children with chronic health conditions (CHCs) are a high-resource population, and further data are needed to identify associations between CHC diagnoses and social needs to optimize health outcomes. In this cross-sectional study of 19 779 pediatric patients screened for social needs in an urban health system, we used logistic regression to evaluate CHC diagnoses and social need. Our independent variables were CHC diagnoses. Our dependent variable was the presence of social need. In the study, 2247 of 11 071 (20%) children with CHCs identified need. Children with CHCs were more likely to have a social need than children without CHCs (adjusted odds ratio: 1.56; 95% confidence interval: 1.44-1.68). Children with autism/developmental delay were most likely to have a social need. Children with autism/developmental delay, anxiety/depression, and asthma were most likely to report specific social needs. Health systems should screen for these families' needs to improve health outcomes.

Safety of High-Flow Nasal Cannula Outside the ICU for Previously Healthy Children With Bronchiolitis.

BACKGROUND: High-flow nasal cannula (HFNC), a form of noninvasive respiratory support, is effective for the treatment of respiratory distress in ICUs. Although HFNC has been used outside of the ICU, there is little research that examines its safety in this less-monitored setting. METHODS: Children ≤ 24 months old admitted with bronchiolitis to a pediatric floor at a tertiary care center from April 1 2013, to March 31 2015, were identified by using standard diagnostic codes. Exclusion criteria were concomitant pneumonia or complex comorbidities. Demographic and clinical characteristics were abstracted. Outcomes included transfer to the ICU, higher levels of respiratory support, intubation, pneumothorax, or aspiration events. RESULTS: Eighty children admitted with bronchiolitis who were treated with HFNC while on the pediatric floor were examined. The median age was 4.6 months, 45% were girls, and the majority were either Hispanic (41%) or black (36%). Flow ranged from 3 to 10 L/min. Thirty-three subjects (41% of the sample) required subsequent transfer to the ICU. No children were intubated or developed a pneumothorax. Eighty-three percent were fed while on HFNC. No children had an aspiration event. CONCLUSIONS: HFNC may be a safe modality of respiratory support outside of the ICU for children ages ≤ 24 months with bronchiolitis and without comorbidities up to a maximum flow of 10 L/min. There were no adverse events among the subjects who were fed while on HFNC.

Increased risk of incisional hernia after sigmoid colectomy for diverticulitis compared with colon cancer.

BACKGROUND: We aimed to determine if an increased incidence of incisional hernias is present in patients undergoing sigmoidectomy for diverticulitis vs cancer. The pathophysiology of diverticulitis is poorly understood, but might involve a collagen vascular abnormality that can predispose to incisional hernia. STUDY DESIGN: In this IRB-approved, retrospective study, patients who underwent sigmoid colectomies for diverticulitis or cancer between January 2003 and September 2012 were studied. Exclusion criteria included the development of surgical site infections and neoadjuvant chemoradiotherapy. A multivariate logistic regression was used with covariate adjustments for known risk factors for hernia development. RESULTS: Four hundred forty-two patients (mean age 59.3 ± 13.9 years) with a median follow-up of 30 months were analyzed. The incidence of incisional hernia was 15.1% in diverticulitis patients vs 5.8% in the cancer cohort (41 of 271 vs 10 of 171; p = 0.003). Univariate analysis of risk factors associated with postoperative incisional hernia included steroid use (p = 0.007), wound packing (p = 0.001), higher American Society of Anesthesiologists classification (p = 0.001), absorbable suture closure (p = 0.02), blood transfusion (p = 0.04), stoma formation (p = 0.02), increased body mass index (p = 0.008), and history of incisional hernia (p = 0.00008). Multivariate logistic regression demonstrated a persistent association between diverticulitis and hernia development (p = 0.01). Odds of a hernia developing after sigmoidectomy for diverticulitis were 2.82 times greater than in the cancer cohort (95% CI, 1.3-6.6). CONCLUSIONS: The incidence of an incisional hernia developing after a sigmoid colectomy is significantly higher when performed for diverticulitis as compared with cancer. This might be due to a connective tissue disorder, which predisposes to development of both diverticula and hernias.

Genetic risk profiling and gene signature modeling to predict risk of complications after IPAA.

BACKGROUND: Severe pouchitis and Crohn's disease-like complications are 2 adverse postoperative complications that confound the success of the IPAA in patients with ulcerative colitis. To date, approximately 83 single nucleotide polymorphisms within 55 genes have been associated with IBD. OBJECTIVE: The aim of this study was to identify single-nucleotide polymorphisms that correlate with complications after IPAA that could be utilized in a gene signature fashion to predict postoperative complications and aid in preoperative surgical decision making. DESIGN: One hundred forty-two IPAA patients were retrospectively classified as "asymptomatic" (n = 104, defined as no Crohn's disease-like complications or severe pouchitis for at least 2 years after IPAA) and compared with a "severe pouchitis" group (n = 12, ≥ 4 episodes pouchitis per year for 2 years including the need for long-term therapy to maintain remission) and a "Crohn's disease-like" group (n = 26, presence of fistulae, pouch inlet stricture, proximal small-bowel disease, or pouch granulomata, occurring at least 6 months after surgery). Genotyping for 83 single-nucleotide polymorphisms previously associated with Crohn's disease and/or ulcerative colitis was performed on a customized Illumina genotyping platform. The top 2 single-nucleotide polymorphisms statistically identified as being independently associated with each of Crohn's disease-like and severe pouchitis were used in a multivariate logistic regression model. These single-nucleotide polymorphisms were then used to create probability equations to predict overall chance of a positive or negative outcome for that complication. RESULTS: The top 2 single-nucleotide polymorphisms for Crohn's disease-like complications were in the 10q21 locus and the gene for PTGER4 (p = 0.006 and 0.007), whereas for severe pouchitis it was NOD2 and TNFSF15 (p = 0.003 and 0.011). Probability equations suggested that the risk of these 2 complications greatly increased with increasing number of risk alleles, going as high as 92% for severe pouchitis and 65% for Crohn's disease-like complications. CONCLUSION: In this IPAA patient cohort, mutations in the 10q21 locus and the PTGER4 gene were associated with Crohn's disease-like complications, whereas mutations in NOD2 and TNFSF15 correlated with severe pouchitis. Preoperative genetic analysis and use of such gene signatures hold promise for improved preoperative surgical patient selection to minimize these IPAA complications.

Mutations in IRGM are associated with more frequent need for surgery in patients with ileocolonic Crohn's disease.

BACKGROUND: There are no clear criteria for judging the severity of disease in patients with Crohn's disease. Yet classification of patients into low- and high-risk severity groups would benefit both medical and surgical management. At the time of this study, approximately 80 single-nucleotide polymorphisms within 55 genes had been associated with IBD. OBJECTIVE: The aim of this study was to identify genetic determinants (single-nucleotide polymorphisms) that could be markers of Crohn's disease severity by the use of frequency of ileocolic surgery as a surrogate for disease severity. DESIGN: Sixty-six patients (30 male) with ileocolonic Crohn's disease who previously underwent ileocolectomy were retrospectively studied. The severity of Crohn's disease was quantified by dividing the total number of ileocolectomy procedures by the time between IBD diagnosis and the patient's last clinic visit, the rationale being that more severe disease would be associated with a more frequent need for surgery. Genotyping for the 83 single-nucleotide polymorphisms associated with IBD was done on a customized Illumina Veracode genotyping platform. Three genetic models (general, additive, and dominant) were used to statistically quantify the genetic association of the studied single-nucleotide polymorphisms to the frequency of surgery after adjusting for covariates (age, smoking, family history, disease location, and disease behavior). RESULTS: For the entire group the average number of ileocolectomies per patient was 1.7 (range, 1-5) with an average duration of disease of 14.7 years. Single-nucleotide polymorphism rs4958847 in the IRGM gene (immunity-related GTPase family, M) was the most significant single-nucleotide polymorphism in all 3 models tested (p = 0.007) as being associated with ileocolectomy, and it remained significant even after a Benjamini-Hochberg false-discovery correction for multiple observations. Patients carrying the "at-risk" allele for this single-nucleotide polymorphism (n = 20) had an average of 1 surgery every 6.87 ± 1.33 years in comparison with patients carrying the wild-type genotype (n = 46) who averaged 1 surgery in 11.43 ± 1.21 years (p = 0.007, Mann-Whitney U test). CONCLUSIONS: : Single-nucleotide polymorphism rs4958847 in the IRGM gene correlated very significantly with frequency of surgery in patients with ileocolonic Crohn's disease. IRGM is a mediator of innate immune responses and is involved in autophagy. The presence of this IRGM SNP may be a marker for disease severity and/or early recurrence after ileocolectomy and may assist in surgical and medical decision making.

Infliximab and/or azathioprine in the treatment of Crohn's disease-like complications after IPAA.

PURPOSE: Ileal pouch-anal anastomosis continues to be confounded by Crohn's disease-like complications after surgery. Such patients experience significant morbidity and often require either pouch excision or diversion. This study evaluated the effectiveness in our hands of infliximab and/or azathioprine/6-mercaptopurine in treating this patient population. METHODS: We conducted a retrospective chart review of all patients who underwent IPAA who experienced Crohn's disease-like complications (pouch fistulas, stricturing small-bowel disease, or pouchitis unresponsive to antibiotics) after ileostomy closure. Patients were segregated according to treatment (azathioprine/6-mercaptopurine only, infliximab only, or both azathioprine/6-mercaptopurine and infliximab) and evaluated for clinical response defined by significant symptomatic improvement and avoidance of stoma. RESULTS: Of 382 IPAAs, 32 (8.4%) patients developed Crohn's disease-like complications a mean of 17 months after stoma closure. Of these, 22 were treated with azathioprine/6-mercaptopurine and/or infliximab with one lost to follow-up. Overall mean follow-up was 97 ± 11.8 months. Failure rate (requiring stomas) was highest in the fistula group treated with infliximab and azathioprine/6-mercaptopurine (6/13, 46%). Patients with stricturing disease (6) or severe pouchitis (2) were all effectively treated with azathioprine/6-mercaptopurine (5/6) or infliximab (1 patient allergic to azathioprine/6-mercaptopurine) and none of these patients required stomas. In the group not receiving stomas, bowel frequency improved from 8.3 ± 1 to 5.7 ± 0.5 per day (P < .05). CONCLUSION: Fistulizing disease after IPAA has the highest failure/stoma rate (46%) despite treatment with infliximab and/or azathioprine/6-mercaptopurine. IPAA patients with stricturing disease and/or antibiotic resistant pouchitis were successfully treated without stomas and all had resolution of symptoms, which suggests that fistulous disease after IPAA should be treated with infliximab, but stricturing disease and antibiotic resistant pouchitis may be effectively treated with azathioprine/6-mercaptopurine only. Such a protocol will potentially minimize the risks associated with infliximab in this difficult group of patients.

Risk factors for surgical site infections after colorectal resection in diabetic patients.

BACKGROUND: Surgical site infections (SSIs) are a well known complication of gastrointestinal surgery and associated with an increased morbidity, mortality and overall cost. Diabetes mellitus (DM) is a risk factor for SSI. However, there is no clear consensus as to which other risk factors play a significant role. The goal of this study was to identify risk factors associated with SSI in patients with DM undergoing colorectal resection. STUDY DESIGN: A retrospective review was conducted of DM patients who underwent colorectal resection from June 2000 to June 2009 at Milton S Hershey Medical Center, Division of Colorectal Surgery. Individual measures were analyzed using chi-square, t-test, and Mann-Whitney U tests, and statistical significance was confirmed using a multiple logistical regression model. RESULTS: There were 183 DM patients included in the study, 28 (15%) of whom developed SSI. Glucose levels were significantly higher in the SSI group for each time interval, 0 to 6 hours (211 mg/dL, p = 0.03), 0 to 48 hours (176 mg/dL, p = 0.001), and 48 to 96 hours (167 mg/dL, p = 0.012) postoperatively. Other measures significantly associated with SSI included the use of drains (p = 0.05) and the use of prophylactic antibiotics for more than 24 hours (p = 0.02). Body mass index and stoma creation approached statistical significance (p = 0.08, 0.07, respectively). The type of hypoglycemic regimen, immunosuppression, and emergency surgery were not associated with an increased rate of SSI. CONCLUSIONS: Higher than normal glucose control at all postoperative time intervals was associated with SSI. The majority of glucose levels were below the American Diabetes Association recommended level of 200 mg/dL, but patients still developed SSI. Type of perioperative glucose control did not affect the incidence of SSI. These data suggest that DM patients undergoing colectomy should have glucose tightly controlled, avoid placement of drains, and receive antibiotics for less than 24 hours.

Enhanced intestinal expression of the proteasome subunit low molecular mass polypeptide 2 in patients with inflammatory bowel disease.

PURPOSE: Low molecular mass polypeptide 2 is an inducible immunoproteasome subunit. The expression of low molecular mass polypeptide 2 has not been examined in the intestine of patients with inflammatory bowel disease. This study was designed to determine whether the intestinal expression of low molecular mass polypeptide 2 was enhanced in a group of patients with inflammatory bowel disease compared with a group of control patients without inflammatory bowel disease. Moreover, we examined the association between low molecular mass polypeptide 2 expression and histologic pathology in these patients. METHODS: Twenty-one patients participated in the study. These included six control subjects without inflammatory bowel disease, eight patients with ulcerative colitis, and seven patients with Crohn's disease. Intestinal low molecular mass polypeptide 2 expression was evaluated by immunohistochemistry, as well as by Western blot. Histology scores (0-40 severity scale) were determined on the same sections of intestine as those used for low molecular mass polypeptide 2 histochemistry. RESULTS: By immunohistochemistry, low molecular mass polypeptide 2 expression was significantly enhanced (P < 0.05 vs. control subjects) throughout visibly diseased areas of colon, rectum, and ileum from patients with inflammatory bowel disease. Low molecular mass polypeptide 2 expression also was increased in macroscopically normal intestine from patients with inflammatory bowel disease compared with normal tissue from control subjects. There was a significant correlation (P < 0.0001) between low molecular mass polypeptide 2 expression and histologic pathology in our patients. Western blot results confirmed that low molecular mass polypeptide 2 expression was enhanced in patients with ulcerative colitis (3.1-fold) and in patients with Crohn's disease (3.5-fold). CONCLUSIONS: Intestinal low molecular mass polypeptide 2 expression is significantly increased in inflammatory bowel disease. The association between intestinal low molecular mass polypeptide 2 expression and histologic pathology suggests that this proteasome subunit plays a role in the pathogenesis of inflammatory bowel disease.

Laparoscopic total abdominal colectomy in the acute setting.

We report results from a single surgeon's 10-year team experience with laparoscopic total abdominal colectomy. We review our series, which includes a large subgroup of ill, high-risk patients with acute colitis requiring urgent surgery. From 1993 to 2003, we performed 65 laparoscopic total abdominal colectomies. All patients referred for total abdominal colectomy were offered the laparoscopic approach. We prospectively collected the following data on all patients: demographics, surgical indications, preoperative status, duration of surgery, intraoperative blood loss, operative complications, length of stay, subsequent operations, patient satisfaction, and lessons learned from our team experience. Preoperative diagnoses included ulcerative colitis (n=55), Crohn's colitis (n=3), colonic inertia (n=4), and familial adenomatous polyposis (n=3). Among the patients with inflammatory bowel disease, 70% of cases were performed on ill patients, refractory to medical management, requiring urgent surgery. This subgroup was managed with laparoscopic total abdominal colectomy and Brooke ileostomy, with ileoanal pouch anastomosis deferred. Operative times were long, ranging from 6 to 11 hours. Mean intraoperative blood loss was 200 ml. Mean length of stay was 4.3 days and ranged from 2 to 13 days. There were no conversions to open surgery and there were no deaths. Complications occurred in 12% of patients and included intra-abdominal abscess (n=2), wound infection (n=3), stoma stenosis (n=1), and incisional hernia (n=2). Postoperative patient satisfaction was high. Subsequent operations, including restorative proctectomy, were also performed laparoscopically. Laparoscopic total abdominal colectomy is technically challenging and requires a team approach but offers patients significant benefit in length of stay and surgical recovery. This operation can be effectively used with minimal morbidity in difficult, ill patients requiring urgent surgery.
