Evolving Availability and Standardization of Patient Attributes for Matching

Variation in availability, format, and standardization of patient attributes across health care organizations impacts patient-matching performance. We report on the changing nature of patient-matching features available from 2010-2020 across diverse care settings. We asked 38 health care provider organizations about their current patient attribute data-collection practices. All sites collected name, date of birth (DOB), address, and phone number. Name, DOB, current address, social security number (SSN), sex, and phone number were most commonly used for cross-provider patient matching. Electronic health record queries for a subset of 20 participating sites revealed that DOB, first name, last name, city, and postal codes were highly available (\u3e90%) across health care organizations and time. SSN declined slightly in the last years of the study period. Birth sex, gender identity, language, country full name, country abbreviation, health insurance number, ethnicity, cell phone number, email address, and weight increased over 50% from 2010 to 2020. Understanding the wide variation in available patient attributes across care settings in the United States can guide selection and standardization efforts for improved patient matching in the United States

Combined Forward-Backward Asymmetry Measurements in Top-Antitop Quark Production at the Tevatron

The CDF and D0 experiments at the Fermilab Tevatron have measured the asymmetry between yields of forward- and backward-produced top and antitop quarks based on their rapidity difference and the asymmetry between their decay leptons. These measurements use the full data sets collected in proton-antiproton collisions at a center-of-mass energy of $\sqrt s =1.96$ TeV. We report the results of combinations of the inclusive asymmetries and their differential dependencies on relevant kinematic quantities. The combined inclusive asymmetry is $A_{\mathrm{FB}}^{t\bar{t}} = 0.128 \pm 0.025$. The combined inclusive and differential asymmetries are consistent with recent standard model predictions

Management of Overfiltering and Leaking Blebs With Autologous Blood Injection

We read with interest the report by Dr Leen et al1 in the August 1995 issue of the Archives. We report herein two possible complications associated with this procedure. REPORT OF A CASE. A 50-year-old white man with a normal right eye underwent pars plana vitrectomy in the left eye in 1980 for recurrent, macula-sparing toxoplasma retinochoroiditis. He had an intracapsular cataract extraction in 1982 and a secondary anterior chamber intraocular lens placement in 1986. Subsequently, bullous keratopathy developed. He underwent a successful penetrating keratoplasty and intraocular lens exchange in November 1990, but severe, secondary angle-closure glaucoma developed, which necessitated a trabeculectomy with mitomycin (0.5 mg/mL for 5 minutes) at the inferior limbus in April 1991. In November 1991 his best corrected visual acuity was 20/40 OS.Thereafter, his intraocular pressure slowly fell to 1 mm Hg, despite six trichloroacetic acid treatments to the bleb. By November 1993, mil
