Right sided colorectal cancer increases with age and screening should be tailored to reflect this: a national cancer database study.

BACKGROUND: In the United States, colorectal cancer (CRC) screening and surveillance is recommended until age 75. However, rates of surgery for CRC are greatest in the elderly, questioning current guidelines. Tumor sidedness is an emerging prognostic marker that may help guide screening and treatment decisions, with specific benefit evaluating CRC anatomic distribution in the elderly. Our objective was to investigate the anatomical distribution of CRC in the elderly and factors associated with right-sidedness. METHODS: The National Cancer Database (2004-2016) was used to identify elderly patients with CRC. Cases were stratified by tumor sidedness and elderly subgroups: 65-74, 75-84, and ≥ 85 years of age, and further categorized by primary site. Multivariate analysis identified factors associated with CRC right-sidedness. The outcomes were CRC sidedness in the elderly, the anatomic distribution by age group, and factors associated with right-sidedness. RESULTS: There were 508,219 colorectal cancer patients aged over 65 years identified, 54% of whom had a right-sided cancer. The right-sided incidence rates by age group were 49% (65-74 years), 58.2% (75-84 years), and 65.9% (≥ 85 years) (p < 0.001). Variables associated with right-sidedness were age (OR 1.032; 95% CI 1.031-1.033; p < 0.001), female sex (OR 1.541; 95% CI 1.522-1.561; p < 0.001), Medicare (OR 1.023, 95% CI 1.003-1.043; p = 0.027), year of diagnosis ≥ 2010 (OR 1.133; 95% CI 1.119-1.147; p < 0.001), tumor size > 5 cm (OR 1.474; 95% CI 1.453-1.495; p < 0.001), pathologic stage IV (OR 1.036; 95% CI 1.012-1.060; p = 0.003). CONCLUSIONS: We found higher rates of right-sided colon cancer in the 75 and above age group. This is a population who would benefit greatly from a high-quality and complete colonoscopy for early diagnosis. As screening and surveillance for this age group are not currently recommended, our findings question the lack of universal recommendation of colonoscopy in patients over 75 years old. Guidelines for CRC screening and surveillance should consider the colon cancer right-shift in the elderly population. Based on these results, we recommend thorough assessment of the proximal colon in the elderly.

Predictors of complications from stoma closure in elective colorectal surgery: an assessment from the American College of Surgeons National Surgical Quality Improvement Program (ACSNSQIP).

BACKGROUND: There is significant morbidity after diverting ileostomy closure, so identifying predictors of complications could be of great benefit. The aim of our study was to evaluate the incidence and risk factors for postoperative morbidity after elective ileostomy closure. METHODS: The ACS-NSQIP dataset was evaluated for elective ileostomy closures from 1/1/2015 to 12/31/2016. Demographic characteristics, operative, and postoperative outcomes were evaluated. The primary outcome was 30-day major morbidity (Clavien class III and greater). Secondary outcomes were rates and predictors of major morbidity, superficial site infection (SSI), reoperation, and readmission from multivariate logistic regression modeling. RESULTS: We retrospectively evaluated 1885 patients. The median operative time was 65 (IQR 50-90) minutes and median length of stay was 3 (IQR 2-5) days. Major morbidity was recorded in 6.7%, including mortality (1.0%), deep/organ space SSI (2.6%), dehiscence (0.8%), reintubation (0.5%), sepsis (1.7%), septic shock (0.8%), and reoperation (3.7%). Readmission was recorded in 9.7% and 6.2% had SSI. Multivariate logistic regression showed male sex (OR 1.584; 95% CI 1.068-2.347; p = 0.022) and longer operative time (OR 1.004; 95% CI 1.001-1.007; p = 0.009) were among those variables associated with increased odds of major morbidity. Dyspnea (OR 2.431; 95% CI 1.139-5.094; p = 0.021) and longer operative time (OR 1.003; 95% CI 1.001-1.007; p = 0.034) were among the independent risk factors for SSI. Male sex (OR 2.246; 95% CI 1.297-3.892; p = 0.004, chronic obstructive pulmonary disease (OR 2.959; 95% CI 1.153-7.591; p = 0.024), and longer operative time (OR 1.005; 95% CI 1.001-1.009; p = 0.011) were associated with increased odds of reoperation. Chronic obstructive pulmonary disease (OR 2.578; 95% CI 1.338-4.968; p = 0.005), wound infection (OR 2.680; 95% CI 1.043-6.890; p = 0.041), and inflammatory bowel disease (OR 2.565; 95% CI 1.203-5.463; p = 0.015) were associated with increased odds of readmission. CONCLUSIONS: Elective stoma closure has significant risk of morbidity. Patients with longer operative times were at increased risk for major morbidity, overall SSI, and reoperation. From the analysis, factors specifically associated with major morbidity, overall infectious complications, readmissions, and reoperations were identified. This information can be used to prospectively prepare for these high-risk patients, potentially improving postoperative outcomes.

A National study on the adoption of laparoscopic colorectal surgery in the elderly population: current state and value proposition.

BACKGROUND: The economic and clinical benefits of laparoscopic colorectal surgery are proven, yet may be underutilized in appropriate cases, especially in the elderly. Since the elderly constitute the greatest colorectal surgical volume, our goal was to identify trends in utilization and impact of laparoscopy in this cohort. METHODS: A national review of elective inpatient colorectal resections from the Premier Inpatient Database between 2010 and 2015 was performed. Patients were included if elderly (≥ 65 years), then grouped into open or laparoscopic procedures. The main outcome measures were trends in utilization by approach and total costs for the episode of care, length of stay (LOS), readmission, and complications by approach in the elderly. Multivariable regression models controlled for differences across platforms, adjusting for patient demographic, comorbidities and hospital characteristics. RESULTS: In 70,655 elderly patients evaluated, laparoscopic adoption remained lower than open throughout the study period. Rates increased until 2013, then declined, with increasing rates of open surgery. Laparoscopy was associated with significantly lower mean total costs ($4012 less/case), complications and readmissions (36% and 33% less, respectively), and shorter LOS (2.6 less days) than open cases (all p < 0.0001). When complications occurred, they were less severe and the readmission episodes were less costly with laparoscopy than open colorectal surgery. CONCLUSION: The adoption of laparoscopy in the elderly has lagged behind open surgery and even declined in recent years despite being associated with improved clinical outcomes and reduced cost. With this tremendous value proposition to increase use of laparoscopic surgery in the elderly, further work needs to evaluate root causes of the disparity.

The impact of managed care on substance abuse treatment: a report of the American Society of Addiction Medicine.

This report examines the impact of managed care (MC) and related developments on substance abuse treatment, and evaluates how it has been associated with a decline in the availability of proper treatment for many addicted patients. A trend toward carve-out and for-profit MC organizations is associated with lower financial incentives for intensive treatment than in earlier staff-model and not-for-profit MC organizations. The value of substance abuse insurance coverage has declined by 75% between 1988 and 1998 for employees of mid-to large-size companies, compared with only an 11.5% decline for general health insurance. The shift towards MC has also been associated with a drastic reduction in frequency and duration of inpatient hospitalization, and there is no clear evidence that this reduction has been offset by a corresponding increase in outpatient support. In a survey of physicians treating addiction, the majority felt that MC had a negative impact on detoxification and rehabilitation, and on their ethical practice of addiction medicine.

Network Therapy for addiction: assessment of the clinical outcome of training.

Mental health practitioners in the office setting are often seen as deficient in addiction treatment skills. Relevant training in often quite limited, and trainees are generally not introduced in an effective office-based modality. We studied the feasibility of teaching beginning therapists how to apply Network Therapy, a cognitive-behavioral approach to achieving abstinence and preventing relapse that augments individual therapy with support from family and friends. The therapists were 19 psychiatric residents without experience in substance abuse treatment or outpatient therapy, and the patients were 24 cocaine-dependent patients who received a 24-week course of Network treatment. The patients remained in treatment for an average of 15.4 weeks. Seventy-nine percent of their observed weekly urine toxicologies were negative for cocaine, and 42% of patients produced clean urines in the 3 weeks immediately before termination. The overall outcome compares favorably with that reported in studies on cocaine treatment where experienced therapists were employed. Our results suggest that naive mental health trainees can be taught to apply Network Therapy for effective substance abuse management. This is particularly relevant to technology transfer for general mental health trainees, who are often thought to be perceived to be refractory to learning about the outpatient management of addiction.
