Evaluating the impact of using a wound-specific oral nutritional supplement to support wound healing in a rehabilitation setting.

Chronic wounds adversely affect patient quality of life, increase the risk of mortality, and impose high costs on healthcare systems. Since protein-energy malnutrition or specific nutrient deficiencies can delay wound healing, nutritionally focused care is a key strategy to help prevent or treat the occurrence of non-healing wounds. The objective of our study of inpatients in a rehabilitation hospital was to quantify the effect of daily wound-specific oral nutritional supplementation (WS-ONS) on healing chronic wounds. Using electronic medical records, we conducted a retrospective analysis of patients with chronic wounds. We identified records for (a) a treatment group who received standard wound care + usual hospital diet + daily WS-ONS for ≥14 days, and (b) a control group who received standard wound care + a usual hospital diet. We collected data for demographics, nutritional status, and wound-relevant health characteristics. We examined weekly measurements of wound number and sizes (surface area for superficial wounds or volume for non-superficial wounds). There were 341 patients identified, 114 with 322 wounds in the treatment group and 227 patients with 420 wounds in the control group. We found that rehabilitation inpatients who were given nutritional support had larger wounds and lower functional independence on admission. At discharge, wound area reduction (percent) was nearly two-fold better in patients who were given daily WS-ONS + usual hospital diet compared to those who consumed usual diet only (61.1% vs 34.5%). Overall, weekly wound improvement (lowered wound area or wound volume) was more likely in the WS-ONS group than in the Control group, particularly from the start of care to week 2. Inpatients with largest wounds and lowest functional independence on admission were most likely to be given WS-ONS, an indication that caregivers recognised the need for supplementation. Week-to-week improvement in wound size was more likely in patients who received WS-ONS than in those who did not. Specifically, wound areas and wound volumes were significantly lower at discharge among patients who were given specialised nutritional support. More research in this field is needed to improve care and reduce healthcare costs.

Association between early postoperative nutritional supplement utilisation and length of stay in malnourished hip fracture patients.

BACKGROUND: Malnutrition in older hip fracture patients is associated with increased complication rates and mortality. As postoperative nutrition delivery is essential to surgical recovery, postoperative nutritional supplements including oral nutritional supplements or tube feeding formulas can improve postoperative outcomes in malnourished hip/femur fracture patients. The association between early postoperative nutritional supplements utilisation and hospital length of stay was assessed in malnourished hip/femur fracture patients. METHODS: This is a retrospective cohort study of malnourished hip/femur fracture patients undergoing surgery from 2008 to 2018. Patients were identified through International Classification of Diseases, Ninth Revision (ICD-9) and Tenth Revision (ICD-10) codes and nutritional supplement utilisation via hospital charge codes. The primary outcome was hospital length of stay. Secondary outcomes included infectious complications, hospital mortality, ICU admission, and costs. Propensity matching (1:1) and univariable analysis were performed. RESULTS: Overall, 160 151 hip/femur fracture surgeries were identified with a coded-malnutrition prevalence of 8.7%. Early postoperative nutritional supplementation (by hospital day 1) occurred in 1.9% of all patients and only 4.9% of malnourished patients. Propensity score matching demonstrated early nutritional supplements were associated with significantly shorter length of stay (5.8 [6.6] days vs 7.6 [5.8] days; P<0.001) without increasing hospital costs. No association was observed between early nutritional supplementation and secondary outcomes. CONCLUSION: Malnutrition is underdiagnosed in hip/femur fracture patients, and nutritional supplementation is underutilised. Early nutritional supplementation was associated with a significantly shorter hospital stay without an increase in costs. Nutritional supplementation in malnourished hip/femur fracture patients could serve as a key target for perioperative quality improvement.

Nutrition risk among an ethnically diverse sample of community-dwelling older adults.

OBJECTIVE: To assess the prevalence of nutritional risk among an ethnically diverse group of urban community-dwelling older adults and to explore if risk varied by race/ethnicity. DESIGN: Demographic characteristics, Katz's activities of daily living and health-care resource utilization were ascertained cross-sectionally via telephone surveys with trained interviewers. Nutrition risk and nutrition symptomology were assessed via the abridged Patient Generated Subjective Global Assessment (abPG-SGA); scores of ≥6 points delineated 'high' nutrition risk. Descriptive statistics and logistic regression analyses were conducted. SETTING: Urban.ParticipantsWhite, Black or Hispanic community-dwelling adults, ≥55 years of age, fluent in English or Spanish, residing in the city limits of Chicago, IL, USA. RESULTS: A total of 1001 participants (37 % white, 37 % Black, 26 % Hispanic) were surveyed. On average, participants were 66·9 years old, predominantly female and overweight/obese. Twenty-six per cent (n 263) of participants were classified as 'high' nutrition risk with 24, 14 and 31 % endorsing decreased oral intake, weight loss and compromised functioning, respectively. Black respondents constituted the greatest proportion of those with high risk scores, yet Hispanic participants displayed the most concerning nutrition risk profiles. Younger age, female sex, Black or Hispanic race/ethnicity, emergency room visits, eating alone and taking three or more different prescribed or over-the-counter drugs daily were significantly associated with high risk scores (P<0·05). CONCLUSIONS: One in four older adults living in an urban community prone to health disparities was classified as 'high' nutrition risk. Targeted interventions to promote healthy ageing are needed, especially for overweight/obese and minority community members.

A Comparative Study of Outcomes Between Single-Site Robotic and Multi-port Laparoscopic Cholecystectomy: An Experience from a Tertiary Care Center.

BACKGROUND: The aim of this study was to compare the outcomes of single-site robotic cholecystectomy with multi-port laparoscopic cholecystectomy within a high-volume tertiary health care center. METHODS: A retrospective analysis of prospectively maintained data was conducted on patients undergoing single-site robotic cholecystectomy or multi-port laparoscopic cholecystectomy between October 2011 and July 2014. A single surgeon performed all the surgeries included in the study. RESULTS: A total of 678 cholecystectomies were performed. Of these, 415 (61%) were single-site robotic cholecystectomies and 263 (39%) were multi-port laparoscopic cholecystectomies. Laparoscopic patients had a greater mean BMI (30.5 vs. 29.0 kg/m2; p = 0.008), were more likely to have undergone prior abdominal surgery (83.3 vs. 41.4%; p < 0.001) and had a higher incidence of preexisting comorbidities (76.1 vs. 67.2%; p = 0.014) as compared to the robotic group. There was no statistical difference in the total operative time, rate of conversion to open procedure and mean length of follow-up between the two groups. The mean length of hospital stay was shorter for patients within the robotic group (1.9 vs. 2.4 days; p = 0.012). Single-site robotic cholecystectomy was associated with a higher rate of wound infection (3.9 vs. 1.1%; p = 0.037) and incisional hernia (6.5 vs. 1.9%; p = 0.006). CONCLUSION: Multi-port laparoscopic cholecystectomy should remain the gold standard therapy for gallbladder disease. Single-site robotic cholecystectomy is an effective alternative procedure for uncomplicated benign gallbladder disease in properly selected patients. This must be carefully balanced against a high rate of surgical site infection and incisional hernia, and patients should be informed of these risks.

Robot-Assisted Abdominoperineal Resection: Clinical, Pathologic, and Oncologic Outcomes.

BACKGROUND: The extralevator approach to abdominoperineal resection is associated with a decreased incidence of rectal perforation and circumferential resection margin positivity translating to lower recurrence rates. The abdominoperineal resection, as such, is an operation associated with poorer outcomes in comparison with low anterior resections, and any improvements in short-term outcomes are likely to be related to surgical technique. Robot assistance in extralevator abdominoperineal resection has shown improvement in these pathologic outcomes. Because these are surrogate markers for local recurrence and disease-free survival, long-term survival data are needed to assess the efficacy of this robot-assisted technique, exclusively in a dedicated abdominoperineal resection cohort. OBJECTIVE: We assessed the perioperative, pathologic, and oncologic outcomes of the robot-assisted extralevator abdominoperineal resection for rectal cancer. DESIGN: This study was a review of a prospective database of patients over a 5-year period. SETTING: Procedures were performed in the colorectal division of a tertiary hospital from April 2007 to July 2012. PATIENTS: Patients with rectal cancer were operated on robotically. Indications for abdominoperineal resection were low rectal cancers invading the sphincter complex or location in the anal canal precluding anastomosis. INTERVENTIONS: All patients received a robot-assisted extralevator abdominoperineal resection. MAIN OUTCOME MEASURES: Operative and perioperative measures, pathologic outcomes, and disease-free survival and overall survival were documented and assessed. RESULTS: Twenty-two patients (15 men) with a mean age of 65.5 years and mean BMI of 28.6 kg/m underwent robotic abdominoperineal resection. Circumferential resection margin was positive in 13.6%. There was 1 tumor/rectal perforation. At a mean follow-up of 33.9 months, overall survival was 81.8% with a disease-free survival of 72.7%. Local recurrence was 4.5%. LIMITATIONS: This was a single-institution study with no comparative open or laparoscopic group. CONCLUSION: Robot-assisted abdominoperineal resection is safe, feasible, and oncologically sound with short-term and long-term outcomes comparable to open and laparoscopic surgery.

Use of wide-screen, high-definition monitors for improving adenoma detection: A prospective, randomized, controlled trial.

BACKGROUND AND AIM: Colonoscopy is sensitive at detecting large polyps; however, a significant polyp miss rate is still recognized. Indicators such as the adenoma detection rate (ADR) and, more recently, the adenoma per colonoscopy rate (APC) are increasingly used to ensure quality in colonoscopy. We carried out a prospective, randomized, controlled study evaluating improvement in adenoma detection between wide-screen, high-definition (WSHD) monitors compared to standard monitors (SD). METHODS: Patients undergoing screening or surveillance colonoscopy were randomized to a WSHD room or SD. Polyp size, location, shape, and histology were recorded. Right-sided polyps were considered to be those proximal to the splenic flexure. RESULTS: A total of 152 patients were enrolled in the study, with 78 (51.3%) and 74 (48.7%) enrolled in the WSHD and SD groups, respectively. A 10% absolute difference in favor of the WSHD group was noted for the ADR (41% vs 31% patients); however, the difference was statistically not significant. In the WSHD and SD groups, APC of 0.9 ± 1.4 versus 0.7 ± 1.4 (P = 0.49) were noted, respectively. For polyps <5 mm, an ADR of 0.3 ± 0.4 versus 0.2 ± 0.4 (P = 0.34) and APC of 0.5 ± 1.1 versus 0.2 ± 0.5 (P = 0.06) were seen in the WSHD and SD groups. CONCLUSION: This study shows a trend toward improvement in ADR, with an increase in APC for small adenomas that approaches statistical significance. WSHD monitors are a one-time, low-cost intervention for improving the quality of colonoscopy with potentially favorable outcomes.

Oncologic and Clinicopathologic Outcomes of Robot-Assisted Total Mesorectal Excision for Rectal Cancer.

BACKGROUND: Minimally invasive rectal cancer surgery is challenging and technically difficult. Robotic technology offers a stable surgical platform with magnified 3-dimensional vision and endowristed instruments, which may facilitate the minimally invasive procedure. Data on short-term and long-term outcomes indicate results comparable to laparoscopic and open surgery. OBJECTIVE: We assessed the perioperative, clinicopathologic, and oncologic outcomes of robotic surgery for rectal cancer. DESIGN: This study was a review of a prospective database of patients over a 7-year period. SETTINGS: Procedures took place in the colorectal division at a tertiary hospital. PATIENTS: From August 2005 to October 2012, 101 patients with rectal cancer were operated on using the robotic approach. Rectal cancers were defined as tumors within 15 cm from the anal verge. INTERVENTIONS: Patients received either a totally robotic or a hybrid laparoscopic-robotic operation with rectal dissection performed robotically. MAIN OUTCOME MEASURES: Operative and perioperative data, pathologic outcomes, and disease-free and overall survival were examined. RESULTS: There were 63 men (62.4%) and 38 women (37.6%) in the study; the mean age was 61.5 years. Mid rectal and low rectal cancers composed 74.2% of cases. Preoperative chemoradiation was given to 74.3% of patients. Four conversions to open surgery occurred. Circumferential margin positivity was 5%, and median lymph node yield was 15. At a mean follow-up of 34.9 months, the disease-free survival was 79.2% and overall survival 90.1%. The mean cost of robotic surgery was $22,640 versus $18,330 for the hand-assisted laparoscopic approach (p = 0.005). LIMITATIONS: This was a single-institution study with no head-to-head comparative group. CONCLUSIONS: Robotic surgery for rectal cancer extirpation is safe and feasible. It has a low conversion rate, satisfies all measures of pathologic adequacy, and offers acceptable oncologic outcomes. Robotic surgery is significantly more expensive than hand-assisted laparoscopic surgery. The absence of randomized data limits recommending it as the standard of care at present.

Using a new evidence-based trauma protocol to improve detection and reduce costs in patients with blunt cardiac injury.

INTRODUCTION: Management of blunt cardiac injury is often discussed in trauma literature due to the lack of a "gold standard" for early identification and cost-effective care. The effectiveness of an evidence-based trauma protocol was assessed by comparing patients treated with the new protocol to those managed with prior practice. METHODS: The data of 80 patients prospectively managed using the new trauma protocol were compared with the medical records of 80 former patients treated according to existing practice. RESULTS: Implementing the new protocol improved detection of abnormal troponin I levels and resulted in cost savings. The length of time inpatients required continuous electrocardiographic monitoring decreased by 4.23 days and echocardiography use dropped by 70%. CONCLUSION: Implementation of the evidence-based trauma protocol at our facility improved the early identification of patients with blunt cardiac injury and reduced the number of laboratory and diagnostic tests.

Impact of nutrition interventions for malnourished patients: Introduction to health economics and outcomes research with findings from nutrition care studies.

Healthcare systems and patients today are challenged by high and ever-escalating costs for care. With increasing costs and declining affordability, public and private healthcare payers are all seeking value in care. As the evidence regarding health benefits of nutrition products and interventional nutrition care is increasing, cost-effectiveness of these interventions needs consideration. Health economics and outcomes research (HEOR) examines the value of healthcare treatments, including nutrition interventions. This review summarizes how HEOR tools are used to measure health impact, that is, the burden of illness, the effect of interventions on the illness, and the value of the nutrition intervention in terms of health and cost outcomes. How studies are designed to compile data for economic analyses is briefly discussed. Then, studies that use HEOR methods to measure efficacy, cost-effectiveness, and cost savings from nutrition care across the healthcare spectrum-from hospitals to nursing homes and rehabilitation centers, to care for community-living individuals, with an emphasis on individuals who are older or experiencing chronic health issues-are reviewed. Overall, findings from HEOR studies over the past decade build considerable evidence to show that nutrition care improves the health of at-risk or malnourished patients effectively and at a reasonable cost. As such, the evidence suggests that nutrition care brings value to healthcare across multiple settings and populations.
