Surveillance for Pressure Injuries on Admission to Inpatient Rehabilitation Hospitals During the COVID-19 Pandemic.

OBJECTIVE: To determine if the incidence of pressure injuries (PIs) on admission to an inpatient rehabilitation hospital (IRH) system of care was increased during the early coronavirus disease 2019 (COVID-19) pandemic period. DESIGN: Retrospective survey chart review of consecutive cohorts. Admissions to 4 acute IRHs within 1 system of care over the first consecutive 6-week period of admitting patients positive for COVID-19 during the initial peak of the COVID-19 pandemic, April 1-May 9, 2020. A comparison was made with the pre-COVID-19 period, January 1-February 19, 2020. SETTING: Four acute IRHs with admissions on a referral basis from acute care hospitals. PARTICIPANTS: A consecutive sample (N=1125) of pre-COVID-19 admissions (n=768) and COVID-19 period admissions (n=357), including persons who were COVID-19-positive (n=161) and COVID-19-negative (n=196). MAIN OUTCOME MEASURES: Incidence of PIs on admission to IRH. RESULTS: Prevalence of PIs on admission during the COVID-19 pandemic was increased when compared with the pre-COVID-19 period by 14.9% (P<.001). There was no difference in the prevalence of PIs in the COVID-19 period between patients who were COVID-19-positive and COVID-19-negative (35.4% vs 35.7%). The severity of PIs, measured by the wound stage of the most severe PI the patient presented with, worsened during the COVID-19 period compared with pre-COVID-19 (χ2 32.04%, P<.001). The length of stay in the acute care hospital before transfer to the IRH during COVID-19 was greater than pre-COVID-19 by 10.9% (P<.001). CONCLUSIONS: During the early part of the COVID-19 pandemic time frame, there was an increase in the prevalence and severity of PIs noted on admission to our IRHs. This may represent the significant burden placed on the health care system by the pandemic, affecting all patients regardless of COVID-19 status. This information is important to help all facilities remain vigilant to prevent PIs as the pandemic continues and potential future pandemics that place strain on medical resources.

The PITCH study: pitcher injuries during the first 30 days of the coronavirus disease 2019 halted Major League Baseball season.

Background: Major League Baseball (MLB) was among the first professional team sports leagues to resume play in the United States after public health measures related to the appearance of coronavirus disease 2019 caused interruptions to preseason training and major alterations to regular season play. There was a high level of concern that these athletes were ill-prepared for competition and would experience an increased risk of injury under the restricted play rules. Methods: The data in our study were compiled using publicly accessible records of players placed on injured lists from 2015 to 2020. These records came from 4 open access websites: rotoworld.com, fangraphs.com, foxsports.com, and spotrac.com. All injuries were confirmed using the transaction database found on the official MLB website (mlb.com). Results: A greater proportion of pitchers were injured during the first 30 days of the 2020 season compared to the first 30 days of any of the 5 prior seasons (29.74% vs. 11.72%, n=2190, P<.001). There was a demonstrated increase in injury risk in 2020 for the following anatomic locations: back and trunk, shoulder, upper arm and elbow, forearm and wrist, and hand and finger (P=.02; confidence interval [0.497-5.783]). When dividing the first month of play in 2020 into equal halves (15 days each), the number of relief pitcher injuries increased with time (60% vs. 78%, P=.04). Lastly, there was no proportional difference in placement on the short-term vs. long-term injured list. Conclusion: A significantly large increase in soft tissue injuries in 2020 compared to the prior 5 seasons predominantly affected the trunk and the upper extremity of pitchers in the first 30 days of play. Alterations to preseason training and regular season play in the 2020 MLB season due to coronavirus disease 2019 may have been particularly disadvantageous to professional pitchers who are positioned at baseline, the most injury prone position.

Assessing balance through the use of a low-cost head-mounted display in older adults: a pilot study.

INTRODUCTION: As the population ages, the prevention of falls is an increasingly important public health problem. Balance assessment forms an important component of fall-prevention programs for older adults. The recent development of cost-effective and highly responsive virtual reality (VR) systems means new methods of balance assessment are feasible in a clinical setting. This proof-of-concept study made use of the submillimeter tracking built into modern VR head-mounted displays (VRHMDs) to assess balance through the use of visual-vestibular conflict. The objective of this study was to evaluate the validity, acceptability, and reliability of using a VRHMD to assess balance in older adults. MATERIALS AND METHODS: Validity was assessed by comparing measurements from the VRHMD to measurements of postural sway from a force plate. Acceptability was assessed through the use of the Simulator Sickness Questionnaire pre- and postexposure to assess possible side effects of the visual-vestibular conflict. Reliability was assessed by measuring correlations between repeated measurements 1 week apart. Variables of possible importance that were found to be reliable (r≥0.9) between tests separated by a week were then tested for differences compared to a control group. Assessment was performed as a cross-sectional single-site community center-based study in 13 older adults (≥65 years old, 80.2±7.3 years old, 77% female, five at risk of falls, eight controls). The VR balance assessment consisted of four modules: a baseline module, a reaction module, a balance module, and a seated assessment. RESULTS: There was a significant difference in the rate at which participants with a risk of falls changed their tilt in the anteroposterior direction compared to the control group. Participants with a risk of falls changed their tilt in the anteroposterior direction at 0.7°/second vs 0.4°/second for those without a history of falls. No significant differences were found between pre/postassessment for oculomotor score or total Simulator Sickness Questionnaire score. Both the force plate and the head-mounted display balance-assessment system were able to detect differences between conditions meant to mask visual and proprioceptive information. CONCLUSION: This VRHMD is both affordable and portable, causes minimal simulator sickness, and produces repeatable results that can be used to assess balance in older adults.
