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.

Role of health services research in producing high-value rehabilitation care.
The overall purpose of this article is to present a framework to help clinicians, researchers, educators, and policy makers better understand the role of health services research in developing and evaluating evidence on value in rehabilitation. The authors believe that rehabilitation professionals have a great opportunity to increase their engagement in describing, evaluating, delivering, and disseminating high-value care, but there are several barriers they need to consider to be most successful.

Comparative benefits and harms of second generation antidepressants and cognitive behavioral therapies in initial treatment of major depressive disorder: systematic review and meta-analysis.
This systematic review sought to identify the benefits and harms of second generation antidepressants and cognitive behavioral therapies (CBTs) in the initial treatment of a current episode of major depressive disorder in adults. It concluded that the available evidence suggests no difference in treatment effects of second generation antidepressants and CBT, either alone or in combination, although small numbers may preclude detection of small but clinically meaningful differences.

The comparative effectiveness of biologics among older adults and disabled rheumatoid arthritis patients in the Medicare population.
Older and disabled rheumatoid arthritis (RA) patients are often not present in large numbers in clinical trials or registries. Using a novel, claims-based clinical effectiveness algorithm with the potential to compare the effectiveness of different biologics among this population using large administrative databases, researchers found that abatacept, adalimumab and etanercept are more effective than infliximab among RA patients initiating biologics.

Incidence and complications of interstitial lung disease in users of tocilizumab, rituximab, abatacept and anti-tumor necrosis factor alpha agents, a retrospective cohort study.
Interstitial lung disease (ILD) is a common extra-articular condition in rheumatoid arthritis (RA), but few studies have systematically investigated its incidence and risk factors in patients receiving anti-tumor necrosis factor-alpha (anti-TNFα) agents or alternate mechanisms of action (MOAs). After examining 13,795 episodes of biologic exposure in 11,219 patients, researchers found no significant differences in the risk of ILD and its related complications between RA patients receiving anti-TNFα agents and those receiving alternate MOA agents.

Grading the strength of a body of evidence when assessing health care interventions: an EPC update.
The purpose of this article is to revise the 2010 guidance on grading the strength of evidence (SOE) of the effectiveness of drugs, devices, and other preventive and therapeutic interventions produced by AHRQ’s Evidence-based Practice Center program. It concluded that no single approach for grading SOE suits all reviews, but a more consistent and transparent approach to reporting summary information will make reviews more useful.

Outcomes with angiotensin-converting enzyme inhibitors vs other antihypertensive agents in hypertensive blacks.
The study’s objective was to evaluate the effectiveness of angiotensin-converting enzyme inhibitors when compared with other antihypertensive agents in hypertensive blacks. It found that in a large cohort of hypertensive blacks, angiotensin-converting enzyme inhibitors were associated with less benefit when compared with calcium channel blockers or thiazide diuretics.
