Education About Specialty Palliative Care Among Nonhealthcare Workers: A Systematic Review.

CONTEXT: Despite the expansion of palliative care (PC) services, the public has little knowledge and holds misperceptions about PC, creating barriers to accessing timely specialty PC. OBJECTIVES: To systematically review the evidence regarding the efficacy of educational interventions to improve knowledge and attitudes about PC among nonhealthcare workers. METHODS: We searched five databases (PubMed/MEDLINE, Embase, CIANHL, Web of Science, and Scopus) for studies investigating educational interventions about specialty PC in adults who identified as patients, caregivers, or members of the public. We included studies that were available in English and had a comparator group. We excluded studies that only sampled health professionals or children. We used the Mixed Methods Appraisal Tool to assess quality and risk of bias. RESULTS: Of 12,420 records identified, we screened 5948 abstracts and assessed 526 full texts for eligibility. Twenty-one articles were extracted for analysis, representing 20 unique educational interventions. Common methodologies included quasi-experimental (9, 45%), randomized controlled trial (4, 20%), and nonrandomized trial (2, 10%). Common components of the educational interventions included video presentations (9, 45%), written materials (8, 40%), and lectures (4, 20%). Content included definition (14, 70%) and philosophy (14, 70%) of PC, distinctions between PC and hospice (11, 55%), and eligibility for PC (11, 55%). Fourteen (70%) interventions showed statistically significant positive differences in either knowledge or attitudes about PC. CONCLUSIONS: While educational interventions can positively impact knowledge and attitudes about PC among nonhealthcare workers, more research is needed to inform the design, delivery, and evaluation of interventions to increase knowledge and attitudes about PC.

Using Wearable Biosensors to Predict Length of Stay for Patients with IBD After Bowel Surgery.

BACKGROUND AND AIMS: It remains unknown whether ambulation or sleep predicts postoperative length of stay for patients with IBD. We aim to identify the utility of wearable biosensors in predicting postoperative length of stay for patients with IBD. METHODS: Associations of postoperative length of stay with step count/sleep duration/sleep efficiency measured by wearable biosensors were examined. The best-fitting multivariable linear regression model predicting length of stay was constructed using stepwise model selection. RESULTS: Final sample included 37 patients. Shorter sleep duration on postoperative day 4 (r = 0.51, p = 0.043) or 5 (r = 0.81, p = 0.0045) or higher sleep efficiency on postoperative day 5 (r = - 0.77, p = 0.0098) was associated with a shorter length of stay. Additionally, a more positive change in sleep efficiency from postoperative day 4-5 was associated with a shorter length of stay (r = - 0.77, p = 0.024). The best-fitting multivariable linear regression model revealed Clavien-Dindo grade 1 (p = 0.045) and interaction between Clavien-Dindo grade 2/3a and mean daily steps (p = 0.00038) are significant predictors of length of stay. The following variables were not significantly associated with length of stay: mean daily steps/sleep duration/sleep efficiency, average rate of change in these three variables, and changes in step count between successive postoperative days 1-5, sleep duration between successive postoperative days 2-5, and sleep efficiency between successive postoperative days 2-4. CONCLUSION: We demonstrated the utility of activity and sleep data from wearable biosensors in predicting length of stay. Patients with more severe complications may benefit more (i.e., reduced postoperative length of stay) from increased ambulation. However, overall, sleep duration/efficiency did not predict length of stay.

Cumulative Histologic Inflammation Predicts Colorectal Neoplasia in Ulcerative Colitis: A Validation Study.

BACKGROUND: Chronic inflammation in ulcerative colitis (UC) is associated with the development of colorectal neoplasia (CRN). A group at St. Mark's Hospital reported a novel cumulative inflammatory index that predicted the development of CRN in UC patients that we validated with an independent, well-described, matched, case-controlled cohort from the University of Chicago. METHODS: Cumulative inflammatory burden (CIB) was calculated by summing each histological inflammatory activity (HIA) score and multiplying it by the length of the surveillance interval. Persistency was defined by the number of surveillance episodes (with a severity score >2) divided by the total number of surveillance procedures. T tests compared the mean and maximum HIA scores, assessing mean and maximum severity, CIB, and persistency. RESULTS: Sixty-two UC patients (26 patients with CRN, 36 control patients without CRN) were analyzed. Fifty-five percent were men, mean disease duration was 20.6 years, and mean age at CRN diagnosis was 43.9. Of the CRN patients, 6 (23%) had colorectal cancer, 16 (62%) had low-grade dysplasia, and 4 (15%) had indefinite dysplasia. Using mean HIA scores, we found CIB to be statistically greater in CRN patients (P = 0.04). Using maximum HIA scores, we found CIB (P = 0.02), mean severity (P = 0.03), and persistency (P = 0.01) to be significantly greater in CRN patients. Maximum severity was numerically greater for mean and maximum HIA scores but did not reach significance. CONCLUSION: Cumulative histologic inflammation is significantly associated with the development of CRN in UC patients. This suggests a management strategy of controlling inflammation to reduce the risk of CRN and may influence the selection of surveillance intervals.

Efficacy and safety of induction therapy with calcineurin inhibitors followed by vedolizumab maintenance in 71 patients with severe steroid-refractory ulcerative colitis.

BACKGROUND: Following induction therapy with a calcineurin inhibitor (CNI) in severe ulcerative colitis, transitioning to vedolizumab as maintenance therapy could be an option. AIM: To report on the largest cohort of patients successfully induced with CNIs who were transitioned to vedolizumab maintenance therapy. METHODS: This is a retrospective observational study of adult patients with severe steroid-refractory ulcerative colitis. Patients were included if they were induced with a CNI followed by maintenance therapy with vedolizumab between January 2014 and December 2018. The primary endpoint was colectomy-free survival. Secondary endpoints included survival without vedolizumab discontinuation as well as clinical, steroid-free and biochemical remission at week 14. RESULTS: A total of 71 patients (59% male) were treated with vedolizumab after induction therapy with CNIs for severe steroid-refractory colitis. Patients were followed for a median time of 25 months (IQR 16-36). Colectomy-free survival rates from vedolizumab initiation were 93% at 3 months, 67% at 1 year and 55% at 2 years. At the end of induction with vedolizumab at week 14, 50% of patients were in clinical remission, and 62% of patients had a normal CRP. At 1 and 2 years following vedolizumab initiation, 43% and 28% of patients were still on vedolizumab respectively. Vedolizumab was dose escalated to infusions every 4 weeks in 44% of patients. The median time to dose escalation was 5.6 months (IQR 4.1-8.2). No serious adverse events were recorded in our patient cohort. CONCLUSIONS: Transitioning to vedolizumab following induction of remission with CNIs is effective and safe.

Low-Dose Metronidazole is Associated With a Decreased Rate of Endoscopic Recurrence of Crohn's Disease After Ileal Resection: A Retrospective Cohort Study.

BACKGROUND AND AIMS: Recurrence of Crohn's disease after surgical resection and primary anastomosis is an important clinical challenge. Previous studies have demonstrated the benefit of imidazole antibiotics, but have been limited by adverse events and medication intolerance. We evaluated whether administration of low-dose metronidazole [250 mg three times per day] for 3 months reduces endoscopic postoperative recurrence rates. METHODS: We performed a retrospective cohort study of patients with Crohn's disease who underwent ileal resection with a primary anastomosis and subsequently received care at our center. We compared the cases who received low-dose metronidazole for 3 months with control patients who did not receive this therapy. Data collected included demographics, risk factors for recurrence, and medications before and after surgery. The primary end point was the number of patients with ≥i2 [Rutgeerts] endoscopic recurrence by 12 months. Variables found to be predictive in univariate analysis at p < 0.10 were introduced in the Cox model for multivariate analysis. RESULTS: In all, 70 patients with Crohn's disease [35 cases and 35 controls] met inclusion criteria. Risk factors for Crohn's recurrence were similar between groups. The number of patients with ≥i2 endoscopic recurrence within 12 months following ileal resection was significantly lower in the metronidazole group [7 of 35 patients; 20%] compared with the number in the control group [19 of 35 patients; 54.3%] [p = 0.0058]. Eight participants [22.9%] in the metronidazole group experienced adverse events, and 3 of these patients [8.6%] discontinued the therapy. CONCLUSION: Low-dose metronidazole reduces endoscopic recurrence of Crohn's disease postoperatively and is well tolerated. This intervention should be considered as a therapy option following ileocolonic resection.

Real-World Experience with Tofacitinib in IBD at a Tertiary Center.

BACKGROUND AND AIMS: Many inflammatory bowel disease (IBD) patients do not respond to medical therapy. Tofacitinib is a first-in-class, partially selective inhibitor of Janus kinase, recently approved for treating patients with ulcerative colitis (UC). We describe our experience with the use of tofacitinib for treatment of patients with moderate-to-severe IBD. METHODS: This is a retrospective, observational study of the use of tofacitinib in IBD. Patients with medically resistant IBD were treated orally with 5 mg or 10 mg twice daily. Clinical response and adverse events were assessed at 8, 26, and 52 weeks. Objective response was assessed endoscopically, radiologically, and biochemically. RESULTS: 58 patients (53 UC, 4 Crohn's, 1 pouchitis) completed at least 8 weeks of treatment with tofacitinib. 93% of the patients previously failed treatment with anti-TNF. At 8 weeks of treatment, 21 patients (36%) achieved a clinical response, and 19 (33%) achieved clinical remission. Steroid-free remission at 8 weeks was achieved in 15 patients (26%). Of the 48 patients followed for 26 weeks, 21% had clinical, steroid-free remission. Of the 26 patients followed for 12 months, 27% were in clinical, steroid-free remission. Twelve episodes of systemic infections were noted, mostly while on concomitant steroids. One episode of herpes zoster infection was noted during follow-up. CONCLUSIONS: In this cohort of patients with moderate-to-severe, anti-TNF resistant IBD, tofacitinib induced clinical response in 69% of the patients. 27% were in clinical, steroid-free remission by 1 year of treatment. Tofacitinib is an effective therapeutic option for this challenging patient population.

Abnormal Pouchogram Predicts Pouch Failure Even in Asymptomatic Patients.

BACKGROUND: Anastomotic complications after restorative total proctocolectomy with IPAA for ulcerative colitis alter functional outcomes and quality of life and may lead to pouch failure. Routine contrast enema of the pouch assesses anastomotic integrity before ileostomy reversal, but its clinical use is challenged. OBJECTIVE: The purpose of this research was to assess the relationship among preoperative clinical characteristics, abnormal pouchography, and long-term pouch complications. DESIGN: This was a retrospective chart review. SETTINGS: The study was conducted at a tertiary care center between 2000 and 2010. PATIENTS: Ulcerative colitis patients with IPAA undergoing pouchography before ileostomy closure were included. MAIN OUTCOME MEASURES: Patient demographics, incidence of pouch-related complications, and findings on pouchogram were recorded. Primary outcome was pouch failure, defined as excision or permanent diversion of the ileoanal pouch. Independent predictors of pouch failure were determined by multivariate regression. RESULTS: A total of 262 patients with ulcerative colitis were included. Contrast extravasation was seen in 27 patients (10.3%): 14 (51.9%) were clinically asymptomatic at the time of pouchogram. Six (22.2%) of 27 patients with extravasation developed pouch failure despite normalization of the pouchogram before ileostomy closure. Forty patients (15.3%) were found to have pouch-anal anastomotic stenosis; only 1 developed pouch failure. Pre-IPAA serum albumin and hemoglobin levels were inversely associated with contrast extravasation (serum albumin: OR = 0.42; hemoglobin: OR = 0.77; p < 0.05). Contrast extravasation was associated with delayed takedown operation (average = 67 d), increased risk (OR = 5.25; p < 0.01), and shorter time (median = 32.0 vs 72.5 mo; HR = 5.88; p < 0.05) to pouch failure, as well as increased risk of pouch-related complications (p < 0.05). LIMITATIONS: The study was limited by its retrospective nature and small number of patients who developed pouch failure. CONCLUSIONS: Pouchography before ileostomy takedown is useful in identifying patients with ulcerative colitis at risk for postoperative complications. Radiologic resolution of IPAA-related leak does not reliably predict healing; caution is warranted in this subgroup. See Video Abstract at http://links.lww.com/DCR/A818.
