Introduction: Unattended clinic visits, or patient no-shows, can have harmful effects on patient health and well being and an unfavorable impact on the revenue stream and financial efficiency of the health system. The objective of this study was to assess potential risk factors associated with clinic no-shows across orthopaedic subspecialties in a large, tertiary care, academic, medical center. Methods: Clinic appointments labeled as “completed” or “no-show” between January 1, 2021 and June 30, 2023, were retrospectively collected from an outpatient orthopaedic department at a single institution. Patient demographic, socioeconomic, and visit characteristics evaluated as potential risk factors for no-shows included patient age, sex, race, social deprivation index (SDI) at the zip code level, documented social support, employment status, insurance coverage, time between appointment creation and appointment date, orthopaedic subspecialty, appointment type (ie, new versus established patient status), and referral status (ie, self-referred versus referral from a medical provider). Variable selection was done with univariate logistic regression analysis, and adjusted risk of no-shows was estimated using multivariable logistic regression. Matching was done to control for potential confounding from patient age and sex, subspecialty, and appointment type. Results: Overall, 148,352 clinic appointments were included in the primary analysis. Multivariable logistic regression analysis before matching cohorts demonstrated statistically significant associations between no-show appointments and advanced age, female sex, self-identified Black or African American race, unemployment, lack of social support, and Foot and Ankle visits. After cohorts were matched, a total of 22,154 clinic appointments were included in the final analysis with an equal number of “completed” and “no-show” visits. Multivariable logistic regression modeling of the matched no-shows and completed visits demonstrated a higher odds of no-show appointments among patients self-identifying as Black/African American, lacking social support, being unemployed, being a student or retiree, having Medicare insurance, and a having a higher SDI. Conclusion: Higher odds of patient no-shows were determined for several patient- and visit-level variables, including Black/African American race, lack of social support, unemployment, Medicare insurance, and higher SDI.

The discovery of Einstein's hidden variables was presented at the previous "Nature of Light" meeting, and revealed that Max Planck's famous quantum formula was incomplete. The complete quantum formula revealed a previously hidden energy constant for light, 6.626 X 10^-34 J/osc (the energy quantum of a single oscillation of light) and a measurement time variable. The "photon" is a time-based collection of sub-photonic elementary particles, namely single oscillations of light. An understanding of the <i>constant</i> speed of light as well as the <i>relative and additive</i> velocities of light's energy quantum is now possible. What emerges is a remarkably fresh and yet classical perspective. Einstein's three-dimensional light-quantum model applied to the recently discovered energy constant suggests the constant energy of an oscillation of light is distributed along its wavelength and is absorbed and emitted as a whole quantum. In a vacuum, light's oscillations travel at the constant speed of light (Lorentzian) regardless of their wavelength. The time-rate (velocity) with which the whole energy quantum of an oscillation is absorbed or emitted varies with its wavelength. The longer the wavelength, the longer it takes for the entire oscillation energy to be absorbed. Light's infinitely variable energy velocities are consistent with the Galilean principle of relative and additive velocities. A realistic mechanism for superluminal absorption and emission becomes apparent and a new corollary is found: <i>Light propagates from every transmitter at the same speed, but reaches receivers at different frequencies, depending on the relative difference between the speed of the transmitter and receiver.</i>

To investigate whether subacromial corticosteroid injections are effective in the treatment of rotator cuff disease, an evidence-based systematic review was undertaken of nine randomized controlled trials that compared subacromial corticosteroid injection with placebo in patients with rotator cuff disease. Each study was systematically evaluated for biases, and outcome measures were scrutinized for statistical significance and clinical importance. One study demonstrated clinically important differences in pain relief. Two studies showed clinically important improvement in range of motion at final follow-up. This systematic review of the available literature indicates that there is little reproducible evidence to support the efficacy of subacromial corticosteroid injection in managing rotator cuff disease.
