Surgical versus non-surgical management for patients with malignant bowel obstruction (S1316): a pragmatic comparative effectiveness trial.
The purpose of this study was to compare surgical versus non-surgical management with the goal of determining the optimal approach for managing malignant bowel obstruction. From May 11, 2015, to April 27, 2020, 221 patients were enrolled, with 199 evaluable participants. The study found no variation between surgery and non-surgery for the primary outcome of good days: mean 42·6 days in the randomized surgery group, 43·9 days (29·5) in the randomized non-surgery group, 54·8 days (27·0) in the patient choice surgery group, and 52·7 days (30·7) in the patient choice non-surgery group. During their initial hospital stay, six participants died, five due to cancer progression and one due to malignant bowel obstruction treatment complications The most common grade 3-4 malignant bowel obstruction treatment complication was anemia.

Age-related differences in pain, function, and quality of life following primary total knee arthroplasty: results from a FORCE-TJR (Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement) cohort.
The purpose of this prospective, multicenter cohort study was to evaluate the differences in pain, function, and quality of life (QoL) reported 1 year after total knee arthroplasty (TKA) across varying age groups. The researchers preoperatively assessed 11,602 unilateral primary TKA patients, and collected demographic data, comorbid conditions, and patient-reported outcome measures including the knee injury and osteoarthritis outcome score (KOOS), KOOS-12, KOOS Joint Replacement, and Short-Form health survey (12-item) and then collected again at 1-year postoperatively. The study found that prior to surgery, patients less than 55 years reported worse KOOS pain (39), function (50), and QoL (18) scores with poor mental health score (47) than other older patient groups. At 1 year after TKA, patients less than 55 years reported lower KOOS pain, function, and QoL scores when compared to patients 75 years or older. The differences in score changes among the age groups were statistically significant but clinically irrelevant. Further statistical analyses revealed that age was a significant predictor for pain, but not for function at 1 year where KOOS pain score was predicted to be higher in patients 75 years or older when compared to patients less than 55 years of age.

Reduced compared with traditional schedules for routine antenatal visits: a systematic review.
This systematic review’s objective was to assess differences in maternal and child outcomes in studies comparing reduced routine antenatal visit schedules with traditional schedules. The search was conducted in multiple databases searching for antenatal (prenatal) care, pregnancy, obstetrics, telemedicine, remote care, smartphones, telemonitoring, and related terms. Abstrackr was used for double independent screening for studies comparing televisits and in person routine antenatal care visits for maternal, child, health care utilization, and harm outcomes. The authors found five randomized controlled trials and five nonrandomized comparative studies that compared reduced routine antenatal visit schedules with traditional schedules. The studies did not find differences between schedules in gestational age at birth, likelihood of being small for gestational age, likelihood of a low Apgar score, likelihood of neonatal intensive care unit admission, maternal anxiety, likelihood of preterm birth, and likelihood of low birth weight. There was also insufficient evidence for numerous prioritized outcomes of interest, including completion of the American College of Obstetricians and Gynecologists-recommended services and patient experience measures.

Telehealth for women's preventive services for reproductive health and intimate partner violence: a comparative effectiveness review.
This comparative effectiveness review was conducted on the effectiveness and harms of telehealth interventions for women's reproductive health and intimate partner violence (IPV) services. A literature search was conducted for randomized controlled trials (RCTs) and observational studies of telehealth strategies for women's reproductive health and IPV versus usual care for the period July 2016 to May 2022. Eight RCTs, 1 nonrandomized trial, and 7 observational studies were included (7 studies of contraceptive care and 9 of IPV services). Telehealth services demonstrated similar care as usual care for contraceptive use, sexually transmitted infections, and pregnancy (low strength of evidence [SOE]). Evidence on abortion was insufficient. Outcomes were also similar between telehealth and usual care interventions to replace or supplement IPV services and comparators for repeat IPV, depression, posttraumatic stress disorder, fear of partner, coercive control, self-efficacy, and safety behaviors (low SOE). Telehealth barriers identified included limited internet access, digital literacy, technical challenges, and confidentiality concerns. Safety strategies increased telehealth use for IPV services. Evidence lacked on access, health equity, or harms.

End-user understanding of qualitative comparative analysis used within evidence synthesis: a mixed-methods study.
This study’s purpose was to identify effective approaches to communicating results from a qualitative comparative analysis (QCA) within a systematic review. Interviews with 11 end-users followed by a randomized experiment with 254 participants provided QCA results for a hypothetical review presented through three formats (text, table, and figure). The authors observed a significant different in subjective comprehension across three presentation formats, with figure and text formats scoring higher compared to the table. Overall, there were no significant different for objective comprehension. However, interpretation (a unique component of QCA results) scores among participants that received the figure format were significantly higher than scores for participants who received the text or table. No significant differences were observed in objective comprehension for configuration interpretation.

The effect of supraceliac versus infraceliac landing zone on outcomes following fenestrated endovascular repair of juxta-/pararenal aortic aneurysms.
The purpose of this study was to assess perioperative outcomes in patients in the Vascular Quality Initiative who underwent juxta-/pararenal FEVAR with supraceliac vs infraceliac sealing. 1,486 Patients who received an elective FEVAR for juxta-/pararenal aortic aneurysms in the Vascular Quality Initiative between 2014 and 2021were identified and included.
The researchers defined supraceliac sealing as proximal sealing in aortic zone 5, or zone 6 with a celiac scallop/fenestration/branch or celiac occlusion. The study’s primary outcomes were perioperative and 3-year mortality, and secondary outcomes were completion endoleaks, in-hospital complications, and variables related with 3-year mortality. The study found that of the included patients, 84% underwent infraceliac sealing, and 16% underwent supraceliac sealing. Of the supraceliac patients, 60% had a celiac fenestration/branch, 31% had a celiac scallop, and 9.2% had a celiac occlusion (intentional or unintentional). Compared with infraceliac sealing, there were no differences after risk-adjusted analysis in perioperative mortality following supraceliac sealing. Supraceliac sealing was associated with lower odds of type-IA completion endoleaks, but higher odds of any complication including cardiac complications, lower extremity ischemia and acute kidney injury when compared with infraceliac sealing. The researchers concluded that supraceliac sealing was associated with lower risk of type IA endoleaks and similar mortality compared with sealing at an infraceliac level. The researchers advise that providers should be aware that supraceliac sealing was related with higher perioperative morbidity.

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.

Serum potassium changes due to concomitant ACEI/ARB and spironolactone therapy: a systematic review and meta-analysis.
The purpose of this study was to provide evidence of serum potassium changes in individuals taking angiotensin-converting enzyme inhibitors (ACEIs) and/or angiotensin receptor blockers (ARBs) concomitantly with spironolactone compared to ACEI/ARB therapy alone. The investigators concluded that treatment with spironolactone in combination with ACEI/ARB therapy increases the mean serum potassium concentration by less than 0.20 mEq/L compared to ACEI/ARB therapy alone.

Comparative effectiveness of clinical and community-based approaches to healthy weight.
The objective of this study was to evaluate if two pediatric weight management interventions delivered to Hispanic, low-income children (one in a health center, the other in a Young Men's Christian Association) were effective in reducing BMI. The authors hypothesized that both would be equally effective. They were unable to establish noninferiority of the modified Healthy Weight and Your Child program. The healthy weight clinic at the health center improved BMI, offering an effective treatment of those disproportionately affected.

Five-year outcomes from a prospective comparative effectiveness study evaluating external-beam radiotherapy with or without low-dose-rate brachytherapy boost for localized prostate cancer.
This retrospective cohort study’s objective was to determine if there were differences in treatment-related regret or survival between prostate cancer patients who received external-beam radiation therapy (EBRT) with or without a brachytherapy boost (EBRT-LDR), over a 5-year period. The cohort included 695 men who met inclusion criteria and received either EBRT (n=583) or EBRT-LDR (n=112). Men who received either treatment reported clinically worse urinary irritation and bowel function through 3 years but resolved after 5 years. Men who received EBRT-LDR continued to report moderate- to-big problems with urinary function bother and frequent urination at 5 years. There was no difference in treatment-related regret or survival between patients who received either treatment.

Comparative effectiveness of machine learning approaches for predicting gastrointestinal bleeds in patients receiving antithrombotic treatment.
The purpose of this retrospective cross-sectional study was to compare the performance of 3 machine learning approaches with the commonly-used HAS-BLED (hypertension, abnormal kidney and liver function, stroke, bleeding, labile international normalized ratio, older age, and drug or alcohol use) risk score in predicting antithrombotic-related gastrointestinal bleeding (GIB). The machine-learning models were regularized Cox proportional hazards regression (RegCox), random survival forests, and extreme gradient boosting (XGBoost). Findings showed that the machine learning models revealed similar performance in identifying patients at high risk for GIB after being prescribed antithrombotic agents. Two models (RegCox and XGBoost) performed modestly better than the HAS-BLED score.

Therapies for clinically localized prostate cancer: a comparative effectiveness review.
In this study, the investigators sought to identify new information evaluating clinically localized prostate cancer therapies. The investigators concluded that radical prostatectomy reduced mortality vs watchful waiting in clinically detected localized prostate cancer but caused more harms. Effectiveness may be limited to younger men and those with intermediate risk disease. Active monitoring resulted in little to no mortality difference vs radical prostatectomy or external beam radiation plus androgen deprivation.

Outcomes after truncal ablation with or without concomitant phlebectomy for isolated symptomatic varicose veins (C2 disease).
This study looked outcomes of patients with varicose veins (C2 disease) who were treated with venous ablation alone or ablation plus phlebectomy using the Vascular Quality Initiative Varicose Vein Registry. Data between January 2015 and March 2015 was used to investigate postoperative as well as long-term clinical and patient-reported outcomes among patients with documented symptomatic C2 disease undergoing truncal endovenous ablations alone and combined ablation and phlebectomy. Out of 3375 patients, 40.1% underwent isolated truncal ablation and the rest had the combined procedure of ablation and phlebectomy. Complications were low for both procedures (8.4% and 8.7%). Overall, improvement in symptoms was experienced by 94.4% of patients with more increases in patients undergoing ablation and phlebectomy than ablation alone. Both procedures are recommended by the authors to be covered by insurance.
