Comparative effectiveness of surveillance colonoscopy intervals on colorectal cancer outcomes in a national cohort of patients with inflammatory bowel disease.
The purpose of this study was to determine the comparative effectiveness of varying colonoscopy intervals on colorectal cancer (CRC) outcomes among patients with inflammatory bowel disease (IBD). Data was from the National Veterans Health Administration. Findings showed that, in a national cohort of patients with CRC-IBD, colonoscopy within 3 years prior to CRC diagnosis was associated with early tumor stage at diagnosis, and colonoscopy within 1 year was associated with a reduced all-cause mortality compared with no colonoscopy, supporting colonoscopy intervals of 1 to 3 years in patients with IBD in order to reduce late-stage CRC and all-cause mortality.

In-hospital outcomes after upper extremity versus transfemoral and transcarotid access for carotid stenting in the Vascular Quality Initiative.
This comparative study examined outcomes for treatment of patients at high risk of carotid endarterectomy using different approaches of carotid artery stenting (CAS). The study compared the effects of transradial or transbrachial (tr/tbCAS) versus more established transfemoral (tfCAS) or transcarotid (TCAR) CAS procedures. Patients were identified from the Quality Initiative registry from January 2016 to December 2021. Among 40,835 CAS identified patients, 962 underwent tr/tbCAS, 28,850 underwent tfCAS, and 21,033 underwent TCAR. Among matched patients who underwent tr/tbCAS versus tfCAS, there was no significant difference in the risk of stroke/death (4.1% vs 2.9), but tr/tbCAS was associated with a higher risk of death (2.4% vs 1.3). In the symptomatic subgroup, tr/tbCAS was associated with a higher risk of stroke/death (6.1% vs 3.9%) and death (3.6% vs 1.7%), but there were no differences in asymptomatic patients. After adjustment for Modified Rankin Scale in patients with preoperative stroke, there were no significant differences in stroke/death or death between groups.

Patient-reported outcomes after external beam radiotherapy with low dose rate brachytherapy boost vs radical prostatectomy for localized prostate cancer: five-year results from a prospective comparative effectiveness study.
The purpose of this study was to compare patient reported outcomes through 5 years following radical prostatectomy or external beam radiation therapy with low dose rate brachytherapy boost for localized prostate cancer. The researchers enrolled men 80 years of age or under who had localized prostate adenocarcinoma and followed them longitudinally from 2011 to 2012. The study found that when compared with radical prostatectomy, external beam radiation therapy with low dose rate brachytherapy boost was related with clinically meaningful worse urinary irritative/obstructive and better urinary incontinence function through 5 years. Urinary function bother was similar between groups. Treatment with external beam radiation therapy with low dose rate brachytherapy boost was associated with worse bowel function through 5 years compared to radical prostatectomy. Treatment with external beam radiation therapy with low dose rate brachytherapy boost was associated with better sexual function at 1 year compared to radical prostatectomy, but there was insufficient evidence to reject the supposition that no difference was seen at 3 or 5 years. The researcher concluded that external beam radiation therapy with low dose rate brachytherapy boost was related with clinically meaningful worse urinary irritative/obstructive and bowel functions but better urinary incontinence function through 5 years after treatment compared to radical prostatectomy.

Generating practice-based evidence in the use of guideline-recommended combination therapy for secondary prevention of acute myocardial infarction.
This study’s goal was to determine if variation in real-world practice of guideline-recommended combination therapy for secondary prevention of acute myocardial infarction (AMI) reflects poor quality-of-care or a balance of outcome tradeoffs among patients. Medicare fee-for-service beneficiaries hospitalized 2007-2008 for AMI were included. Treatment within 30-days post-discharge was grouped into one of eight possible combinations for the three drug classes: beta-blockers, angiotensin-converting enzyme inhibitors/angiotensin-receptor blockers, and statins. Outcomes looked at included one-year overall survival, one-year cardiovascular-event-free survival, and 90-day adverse events. Results were found that each drug combination was observed in the final sample (N = 124,695), with 35.7% having all three, and 13.5% having none. There were both treatment benefits and harms in patients with AMIs with higher rates of guideline-recommended treatment.

Utility of automated data-adaptive propensity score method for confounding by indication in comparative effectiveness study in real world Medicare and registry data.
The authors assessed the utility of an automated data-adaptive analytic approach for confounding adjustment when both claims and clinical registry data are available. Using a comparative study example of carotid artery stenting vs. carotid endarterectomy with strong confounding by indication, they found that the automated data-adaptive propensity score performed better than the investigator-specified propensity score in general, but both claims and registry data were needed to adequately control for bias.

Retroperitoneal versus transperitoneal approach for open repair of complex abdominal aortic aneurysms.
This retrospective analysis compared the outcomes of a transperitoneal approach (TP) versus the retroperitoneal approach (RP) for infrarenal abdominal aortic aneurysm (AAA) repair. Several studies have found an advantage for the RP approach. Among a cohort of 1,195 patients identified 729 (61%) underwent cAAA repair via a TP approach and 39% via an RP approach. After adjustment, the RP approach was associated with lower odds of peri-operative death (4.0% versus 7.2%) and lower odds of any major, cardiac, or wound complications and post-operative sepsis. Despite this, the proportion of repairs using an RP approach decreased between 2011 to 2015 and 2016 to 2019.

Therapeutic hyperthermia is associated with improved survival in afebrile critically ill patients with sepsis: a pilot randomized trial.
This study’s objective was to test the hypothesis that forced-air warming of critically ill afebrile sepsis patients improves immune function compared to standard temperature management. Patients were considered eligible patients if they were mechanically ventilated septic adults with: 1) a diagnosis of sepsis within 48 hours of enrollment; 2) anticipated need for mechanical ventilation of greater than 48 hours; and 3) a maximum temperature less than 38.3°C within the 24 hours prior to enrollment. Intervention treatment was external warming using a forced-air warming blanket for 48 hours, with a goal temperature 1.5°C above the lowest temperature documented in the previous 24 hours. The authors enrolled 56 patients in this randomized, controlled trial. Participants allocated to external warming had lower 28-day mortality (18% vs 43%) and more 28-day hospital-free days. No differences were observed between the groups in HLA-DR expression or IFN-γ production.

Stakeholder engagement in a comparative effectiveness/implementation study to prevent Staphylococcus aureus infection recurrence: CA-MRSA Project (CAMP2).
The purpose of this study was to determine whether the presence and participation of a stakeholder committee would positively impact the effectiveness of the design and execution of a home-based Methicillin-resistant Staphylococcus aureus and methicillin-sensitive Staphylococcus aureus infection prevention intervention. The trial utilized community health workers to implement infection prevention protocols in participant’s homes, including home visits, sampling household surfaces at baseline and then three months, and obtaining surveillance cultures from index patients and household members. The study assembled and convened The Clinician and Patient Stakeholder Advisory Committee (CPSAC), comprised of New York-based federally qualified health centers (FQHCs) and community health emergency departments, laboratory and clinical researchers, clinicians, and patient stakeholders. The CPSAC was tasked with trial oversight and shared decision-making and troubleshooting, and convened both in person and remotely. The researchers concluded that the inclusion and engagement of the CPSAC during the trial design and implementation was highly effective in addressing and resolving challenges in both participant recruitment and home visits.

A multicentered randomized controlled trial comparing the effectiveness of pain treatment communication tools in emergency department patients with back or kidney stone pain.
The purpose of this trial was to compare the effectiveness of three approaches for communicating opioid risk during an emergency department visit for a common painful condition. Participants were adult patients with kidney stone or musculoskeletal back pain, randomly assigned to one of three risk communication strategies: a personalized probabilistic risk visual aid, a visual aid and video narrative, or general risk information. Findings showed that an emergency medicine communication tool incorporating probabilistic risk and patient narratives was more effective than general information in mitigating preferences for opioids in the treatment of pain but was not more effective with respect to opioid use or risk recall.

Association between pelvic nodal radiotherapy and patient-reported functional outcomes through 5 years among men undergoing external-beam radiotherapy for prostate cancer: an assessment of the Comparative Effectiveness Analysis of Surgery and Radiation (C
In this study, the investigators sought to compare functional outcomes for men receiving prostate and pelvic versus prostate-only radiotherapy, longitudinally over 5 years. The investigators concluded that there were no clinically important differences in disease-specific or general health-related quality of life with the addition of pelvic irradiation to prostate radiotherapy, supporting the use of pelvic radiotherapy when it may be of clinical benefit, such as men with increased risk of nodal involvement.

Effect of computer-assisted cognitive behavior therapy vs usual care on depression among adults in primary care: a randomized clinical trial.
Computer-assisted cognitive behavior therapy (CCBT) has been proposed as a method for improving access to effective psychotherapy, reducing cost, and increasing the convenience and efficiency of treatment for depression. The purpose of this study was to evaluate whether clinician-supported CCBT is more effective than treatment as usual (TAU) in primary care patients with depression and to examine the feasibility and implementation of CCBT in a primary care population with substantial numbers of patients with low income, limited internet access, and low levels of educational attainment.
