Adjustable suture technique is associated with fewer strabismus reoperations in the Intelligent Research in Sight Registry.
This study compared the reoperation rates of patients who underwent strabismus surgery during the first year with or without the adjustable suture technique. This retrospective cohort study looked at a total of 34,872 patients who underwent strabismus surgery with 72% undergoing horizontal muscle surgery, 17% vertical muscle surgery, and 11% combined horizonal and vertical muscle surgery. Adjustable suture surgery rates were 18% of surgeries. The overall 1-year reoperation rate was 7.7%, with 6.0% for patients treated with adjustable sutures and 8.1% for patients treated without adjustable sutures. There was a statistically significant 30% decrease in the odds of 1-year reoperation when adjustable sutures were used, a 40% increase in those with a history of prior strabismus surgery, and a 9% increase per decade of age at surgery.

Validity of breast cancer surgery treatment information in a state-based cancer registry.
Surgery is an important part of early stage breast cancer treatment that affects overall survival. Statewide cancer registries contain data on first course of cancer treatment for all patients diagnosed with cancer but the accuracy of these data are uncertain. In this study, the authors examined validity of breast cancer surgery treatment information in a state-based cancer registry.

Designing a patient-specific search of transplant program performance and outcomes: feedback from heart transplant candidates and recipients.
The Scientific Registry of Transplant Recipients provides transplant program-specific information, but it is unclear what patients and stakeholders need to know. Acceptance criteria for the candidate waitlist and donor organs vary by program and region, but there is no means to search for programs by the clinical profiles of recipients and donors. The authors examined variability in program-specific characteristics that could influence access to transplantation.

Long-term trends in preoperative cardiac evaluation and myocardial infarction after elective vascular procedures.
This retrospective cohort study was performed using data on elective vascular surgery procedures and evaluated long-term trends in post-operative myocardial infarction (POMI) using Vascular Surgery Vascular Quality Initiative (VQI) registry data for patients undergoing carotid endarterectomy (CEA), thoracic endovascular aortic repair (TEVAR), endovascular aortic repair (EVAR), open abdominal aortic aneurysm repair (oAAA), suprainguinal bypass (SIB), and infrainguinal bypass (IIB). A total of 227,837 elective procedures were identified. The overall rate of POMI was 1.3% across all procedures. POMI rates from 2003-05 to 2015-17 for CEA decreased from 0.9% to 0.7%, EVAR from 2% to 7%, IIB from 3.8% to 2.4%, and oAAA from 6.8% to 5.1%. From 2009 to 2017 SIB decreased from 3.06% to 2.95%. However, TEVAR increased from 2.4% to 3.56% for the period 2006 to 2017. CEA, EVAR, IIB, oAAA all showed a significant increase in postoperative statin use.

Impact of acuity circles on outcomes for pediatric liver transplant candidates.
In December 2018, UNOS approved an allocation scheme based on recipients' geographic distance from a deceased donor ("acuity circles"). Previous analyses suggested acuity circles (AC) would reduce waitlist mortality overall, but their impact on pediatric subgroups was not considered. In this study, the investigators applied Scientific Registry of Transplant Recipients data from 2011-2016 towards the Liver Simulated Allocation Model (LSAM) to compare outcomes by age and illness severity for the UNOS-approved AC and the existing Donor Service Area (DSA)/Region-based allocation schemes.

Short-term quality of life after myomectomy for uterine fibroids from the COMPARE-UF fibroid registry.
Investigators compared women's perception of their short-term health-related quality of life measures and reported time to return to usual activities and return to work for different routes of myomectomy. Using data from the Comparing Options for Management: Patient-centered Results for Uterine Fibroids (COMPARE-UF) registry, and including abdominal and laparoscopic myomectomy procedures, they found that women who underwent myomectomy had substantial improvement in health-related quality of life, regardless of route of myomectomy; abdominal myomectomy was associated with a nearly 2-week longer time to return to work than laparoscopic myomectomy.

Projected 20- and 30-year outcomes for pediatric liver transplant recipients in the United States.
Researchers aimed to use national registry data and parametric models to project 20- and 30-year post-transplant outcomes for recently transplanted pediatric liver transplant (LT) recipients. Using Scientific Registry of Transplant Recipients data, they found that projected long-term outcomes for recently transplanted pediatric LT recipients are excellent, reflective of substantial improvements in medical care, and informative for physician-patient education and decision making in the current era.

Attribution of adverse events following coronary stent placement identified using administrative claims data.
This study outlines the process used to identify adverse events following coronary stent placement identified with administrative claims data. Deterministic matching was used to link the National Cardiovascular Data Registry (NCDR) CathPCI Registry to Medicare fee-for-service claims for patients aged 65 and older who underwent percutaneous coronary interventions (PCIs) with drug-eluting stents (DESs) between July 2009 and December 2013. Out of 415,306 DES placements in 368,194 patients, 278 (1.1%) were attributed to the same coronary artery in which the DES was implanted during the index PCI. The authors concluded that more in-depth examination will be needed to accurately assess stent safety using claims data alone.

Association of pretransplant and posttransplant program ratings with candidate mortality after listing.
The Scientific Registry of Transplant Recipients (SRTR) is responsible for understandable reporting of program metrics, including transplant rate, waitlist mortality, and posttransplant outcomes. SRTR developed five-tier systems for each metric to improve accessibility for the public. In this study, the researchers investigated the associations of the five-tier assignments at listing with all-cause candidate mortality after listing, for candidates listed July 12, 2011-June 16, 2014.

Comparing Scientific Registry of Transplant Recipients posttransplant program-specific outcome ratings at listing with subsequent recipient outcomes after transplant.
To improve accessibility of program-specific reports to patients, the Scientific Registry of Transplant Recipients released a 5-tier system for categorizing 1-year posttransplant program evaluations. Whether this system predicts subsequent posttransplant outcomes at the time patients are waitlisted has been questioned. IN this study, researchers investigated the association of tier at listing and the corresponding continuous score used for tier assignment, which ranges from 0 (poor outcomes) to 1 (good outcomes), with eventual 1-year posttransplant graft survival.

The relationship between the C-statistic and the accuracy of program-specific evaluations.
The C-statistic of the risk-adjustment model is often used to judge the accuracy of program evaluations. However, the C-statistic depends on the variability in risk for individual transplants and may be inappropriate for determining the accuracy of program evaluations. This simulation study investigated the association of the C-statistic with several metrics of program evaluation accuracy, including categorizing programs into the 5-tier system and identifying programs for regulatory review.

Quantifying the utilization of medical devices necessary to detect postmarket safety differences: a case study of implantable cardioverter defibrillators.
The purpose of this study was to estimate medical device utilization needed to detect safety differences among implantable cardioverter defibrillators (ICDs) generator models and compare these estimates to utilization in practice. The investigators concluded that small safety differences among ICD generator models are unlikely to be detected through routine surveillance given current ICD utilization in practice, but large safety differences can be detected for most patients at anticipated average adverse event rates.

Automating electronic clinical data capture for quality improvement and research: The CERTAIN Validation Project of Real World Evidence.
Washington State's Surgical Care Outcomes and Assessment Program (SCOAP) is a network of hospitals participating in quality improvement (QI) registries wherein data are manually abstracted from EHRs. To create the Comparative Effectiveness Research and Translation Network (CERTAIN), researchers semi-automated SCOAP data abstraction using a centralized federated data model, created a central data repository (CDR), and assessed whether these data could be used as real world evidence for QI and research. They concluded that semi-automated data abstraction may be useful, although raw data collected as a byproduct of health care delivery is not immediately available for use as real world evidence. New approaches to gathering and analyzing extant data are required.

Surgically managed clinical stage iiia-clinical n2 lung cancer in the Society of Thoracic Surgeons Database.
The objective of this study was to characterize the management of clinical stage IIIA-N2 positive (cIIIA-N2) lung cancer in The Society of Thoracic Surgeons General Thoracic Surgery Database. Surgeons achieved excellent short- and long-term results treating predominantly lobectomy-amenable cIIIA-N2 lung cancer. However, prevalent overstaging and abstention from induction therapy suggested "overcoding" of false positives on imaging or variable compliance with current guidelines for cIIIA-N2 lung cancer.

Strategies for handling missing clinical data for automated surgical site infection detection from the electronic health record.
Proper handling of missing data is important for many secondary uses of electronic health record (EHR) data. Data imputation methods can be used to handle missing data, but their use for postoperative complication detection is unclear. Overall, models with missing data imputation almost always outperformed reference models without imputation that included only cases with complete data for detection of SSI overall achieving very good average area under the curve values.

Factors associated with early improvement in low back pain after total hip arthroplasty: A multi-center prospective cohort analyses.
This study identified factors associated with an improvement in low back pain (LBP) at six-month follow-up after total hip arthroplasty (THA). It found that among patients reporting severe or moderate LBP preoperatively, 56 percent improved 6 months after surgery. Patients without improvement were more likely to be on Medicare, have a high school education or less, have household income less than $45,000 and have one or more comorbid conditions.

Greater volume of acute normovolemic hemodilution may aid in reducing blood transfusions after cardiac surgery.
The researchers describe the relationship between acute normovolemic hemodilution (ANH) and red blood cell (RBC) transfusions after cardiac surgery using a multicenter registry. They found a significant association between ANH and reduced perioperative RBC transfusion in cardiac surgery. Transfusion reduction is most profound with larger volumes of ANH.

Everolimus eluting stents versus coronary artery bypass graft surgery for patients with diabetes mellitus and multivessel disease.
The researchers used data from the New York State registries to assess the comparative effectiveness of coronary artery bypass graft (CABG) when compared with percutaneous intervention (PCI) using everolimus eluting stents (EES) on short- and long-term cardiovascular outcomes. They found that PCI using EES, the latest generation stents, was associated with lower early risk of death and stroke when compared with CABG surgery.

Using joint registry data from FORCE-TJR to improve the accuracy of risk-adjustment prediction models for thirty-day readmission after total hip replacement and total knee replacement.
The authors argue that registry data offer the opportunity to combine clinical information currently available in registries (such as the Function and Outcomes Research for Comparative Effectiveness in Total Joint Replacement [FORCE-TJR] registry based at the University of Massachusetts Medical School) with the administrative data currently used by CMS. Doing so will improve the risk adjustment for patients having total joint replacement by making the data more accurate and more fair for hospitals and surgeons.

Statin therapy after infrainguinal bypass surgery for critical limb ischemia is associated with improved 5-year survival.
The aim of this study was to determine the effect of long-term statin use after lower extremity bypass grafting on patient-related and graft-related outcomes. It found that statin therapy is associated with a 5-year survival benefit after lower extremity bypass in patients with critical limb ischemia. However, 1-year limb-related outcomes were not influenced by statin use in our large observational cohort of patients undergoing revascularization in New England.
