Blindness increases the risk for hip fracture and vertebral fracture but not the risk for distal radius fracture: a longitudinal follow-up study using a national sample cohort

Impact of vision impairment on discharge destination for patients with hip fracture

Introduction

Vision impairment (VI) due to low vision or blindness is a major sensory health problem affecting quality of life and contributing to increased risk of falls and hip fractures (HF). Up to 60% of patients with hip fracture have VI, and VI increases further susceptibility to falls due to mobility challenges after HF. We sought to determine if VI affects discharge destination for patients with HF.

Materials and methods

Cross-sectional analysis of 2015 Inpatient Medicare claims was performed and VI, blindness/low vision), HF and HF surgery were identified using ICD-9, and ICD-10 codes. Patients who sustained a HF with a diagnosis of VI were categorized as HF + VI. The outcome measure was discharge destination of home, skilled nursing facility (SNF), long-term care facility (LTCF) or other.

Results

During the one-year ascertainment of inpatient claims, there were 10,336 total HF patients, 66.82% female, 91.21% non-Hispanic white with mean (standard deviation) age 82.3 (8.2) years. There was an age-related increase in diagnosis of VI with 1.49% (29/1941) of patients aged 65-74, 1.76% (63/3574) of patients aged 75-84, and 2.07% (100/4821) of patients aged 85 and older. The prevalence of VI increased with age, representing 1.5% (29/1941) of adults aged 65-74, 1.8% (63/3574) of adults aged 75-84, and 2.1% (100/4821) of adults aged 85 and older. The age-related increase in VI was not significant (P = 0.235). Patients with HF were most commonly discharged to a SNF (64.46%), followed by 'Other' (25.70%), home (7.15%), and LTCF (2.67%). VI was not associated with discharge destination. Male gender, Black race, systemic complications, and late postoperative discharge significantly predicted discharge to LTCF with odds ratios (95%CI) 1.42 (1.07-1.89), 1.90 (1.13-3.18), 2.27 (1.66-3.10), and 1.73 (1.25-2.39) respectively.

Conclusions

The co-morbid presence of VI was not associated with altered discharge destinations to home, skilled nursing facility, LTCF or other setting.

Impact of COVID-19 pandemic on a world-wide private ophthalmic practice

Purpose

To assess the impact of the COVID-19 pandemic on a worldwide private ophthalmic practice.

Design

In this retrospective study, we reviewed the 2020 monthly outpatient and surgical volume of refractive, cataract, and retinal disease in Aier Eye clinics/hospitals of different regions, including the United States, Germany, Spain, Italy, and six major cities in China (Wuhan, Beijing, Shanghai, Shenyang, Urumqi and Yili). All of these data were compared to those of the same period of 2019.

Results

Overall, during the early stage (2020 January to 2020 April) of COVID-19 outbreak, the outpatient and surgical volume of three main type ocular diseases (refractive, cataract and retinal surgery) showed an obvious reduction and reached the bottom in February in China. The data from the United States, Germany, Spain and Italy revealed the same trend, but the visit count nadir occurred until April, which is consistent with the spread trend of COVID-19 disease around the world. The average change rates of surgery volume (refractive, cataract and retinal surgery) in Chinese centers are 5.59%, -26.38%, 11.76%. The change rates of refractive (REF) and cataract volumes (CAT) in the United States are -8.62% and -10.58%, in Germany are -13.71% and -20.49%, in Spain are 15.35% and 27.97%, in Italy are 30.43% and -22.64%. In addition, the optometry outpatient volumes keep going up since May, with an average increasing rate of 21.18%, ranging from 7.43% to 49.51%.

Conclusion

In conclusion, in this global chain of eye care units, the visit volumes of cataract, retinal and refractive changed significantly with the spread of COVID-19 pandemic. Among them, cataract surgery was the most affected sub-specialty, and refractive surgery and optometry volumes showed a potential growth in the near future. Therefore, medical institutions should make corresponding adjustments to the disease diagnosis and treatment strategies.

Beyond vision:Cataract and health status in old age, a narrative review

Cataract is a leading cause of visual impairment in old age. Lens opacification is notoriously associated with several geriatric conditions, including frailty, fall risk, depression and cognitive impairment. The association is largely attributable to visual impairment, while other mechanisms, associated with extraocular comorbidity and lifestyle, might partly explain this correlation. Available literature suggests that cataract surgery may be effective in decreasing fall risk, improving depressive symptoms and limiting the risk of cognitive impairment and dementia incidence, although intervention studies on these outcomes are still limited. In this review we also emphasize the need to move from the concept of visual acuity to functional vision, especially in the context of the geriatric patient. Research is needed regarding the effect on the cited outcomes of different cataract treatment strategies, such as systematic bilateral versus monolateral surgery and use of different intraocular lenses.

Biomarkers of Vitamin D Metabolism and Hip and Vertebral Fracture Risk: The Multi-Ethnic Study of Atherosclerosis

Studies on associations between biomarkers of vitamin D metabolism and fracture risk have focused predominantly on White or elderly populations and may not be generalizable to relatively healthy multiethnic populations. We tested associations of total 25-hydroxyvitamin D (25[OH]D), the ratio of 24,25-dihydroxyvitamin D3 to 25-hydroxyvitamin D3 (vitamin D metabolite ratio, VDMR), parathyroid hormone (PTH), and fibroblast growth factor-23 (FGF-23) concentrations measured in serum with risk of hip and vertebral fractures in the Multi-Ethnic Study of Atherosclerosis (MESA). Serum 25-hydroxyvitamin D2 and D3 and 24,25-dihydroxyvitamin D3 were measured by liquid chromatography-tandem mass spectrometry (LC-MS/MS). The study cohort of 6466 participants was without clinically apparent cardiovascular disease and was 39% White, 27% Black, 22% Hispanic, and 12% Chinese. The mean age was 62 years, and 53% were female. There were 128 hip and vertebral fractures over a mean follow-up of 14.2 years. 25(OH)D, the VDMR, PTH, and FGF-23 were not significantly associated with fracture risk after adjustment for demographics, diabetes, smoking, systolic blood pressure, body mass index, medication use, albuminuria, and estimated glomerular filtration rate. Principal component analysis did not suggest differences in linear combinations of 25(OH)D, the VDMR, PTH, and FGF-23 between participants who experienced fractures and those who did not. We did not observe significant interaction between race and ethnicity and any biomarker of vitamin D metabolism on fracture risk. In conclusion, none of the four serum biomarkers of vitamin D metabolism investigated showed a significant association with fracture risk in relatively healthy multiethnic populations. © 2022 The Authors.

Hip Fractures and Visual Impairment: Is There a Cause–Consequence Mechanism?

Background: Numerous studies have pointed out how visual impairment relates to falls in the elderly, causing dangerous consequences, such as fractures. The proximal femur fracture is one of the most frequent fracture types related to poor vision. This study investigates the link between fall-related hip fractures and visual impairment. Methods: The present is an observational monocentric case–control study. We collected the ophthalmologic anamnesis and measured the visual acuity of 88 subjects with femur neck fracture (case group), comparing it with 101 adults without fractures and a recent fall history. Results: The results showed no statistical difference between the two groups regarding visual acuity, with a p-value of 0.08 for the right eye and 0.13 for the left one. One of the major ophthalmologic morbidities found was cataracts, present in 48% of the control group and 30% of the case group. Conclusions: The data obtained suggest that visual impairment might not be crucial in determining falls in the elderly.

Analysis of Postoperative Complications and Related Factors Affecting Prognosis in 50 Patients with Distal Radius Fractures

Objective

To explore the postoperative complications of distal radius fractures and analyze the related factors that affect its prognosis.

Methods

The clinical data of 50 patients with distal radius fractures admitted to our hospital from October 2016 to September 2019 were retrospectively analyzed. All patients were followed up for 6–12 months, and their postoperative complications were recorded. Collect general patient information and related clinical data. During the follow-up process, Gartland and Werley wrist function scoring system was used to evaluate the prognosis of patients' joint function. Univariate analysis and multiple logistic regression models were used to analyze the related factors that affected the prognosis of patients.

Results

15 patients with postoperative complications were found during the follow-up period, with an incidence rate of 30.00%. Univariate analysis showed that the patient's age, cause of injury, AO classification, shortened deformity, whether it was osteoporosis, surgical method, whether it was combined with other fractures on the same side, whether it was comminuted fracture, and the time to start postoperative exercise were all related to the distal radius. The prognosis of fractures is related (P < 0.05). Multivariate logistic analysis showed that age, AO classification, surgical method, whether it was combined with other fractures on the same side, whether it was comminuted fracture, and the time to start postoperative exercise were the independent factors affecting the prognosis of distal radius fractures (P < 0.05).

Conclusion

The postoperative complications of distal radius fractures are higher. The prognosis is related to the patient's age, AO classification, surgical method, whether it is combined with other fractures on the same side, whether it is comminuted fracture, and the time to start postoperative exercise. Therefore, choosing an appropriate surgical method and starting exercise in time can effectively improve the recovery of the patient's wrist function and reduce the occurrence of complications.

Changes in Incidences of Chronic and Traumatic Diseases before and after Registration as Visually Disabled

Purpose: To analyze changes in the incidences of chronic and traumatic diseases before and after registration as visually disabled.Methods: The incidence and risk of chronic and traumatic diseases were compared between patients registered as visually disabled from 2005 to 2013 and a control group, selected through 1:1 propensity score matching for age, sex, premium quantile, and residential area distribution. Data from the National Health Insurance Service were used and the observation period was set from 2 years before to 5 years after the time of registration as visually disabled. The incidences (%) of chronic and traumatic diseases at the point of interest were determined as the mean values according to year of registration, and the risk was measured by conditional logistic regression analysis.Results: 131,434 visually disabled patients and the same number of non-visually impaired controls were included. The incidences of chronic disease and fall-related injury were higher in the visually disabled group before registration, but gradually decreased and became similar to the control group after registration. In addition, the risk of developing chronic diseases was higher in the visually disabled group until 2 years after registration, while the risk of fall-related injury remained consistently higher in the visually disabled group during the observation period. The incidence and risk of hip fracture in the visually disabled group increased gradually from approximately 1 year before registration and remained consistently higher than in the control group.Conclusions: People with visual disability have higher incidences of chronic diseases than do non-visually impaired people and are at greater risk of traumatic injuries, such as hip fractures or falls. There is a need to establish community infrastructure and expand welfare services for the prevention and early treatment of comorbidities, both for patients with registered visual disabilities and for patients who have not yet registered.

Impact of Three Waves of the COVID-19 Pandemic on the Rate of Elective Cataract Surgeries at a Tertiary Referral Center: A Polish Perspective

The aim of this study was to assess the effect of three waves of the COVID-19 pandemic on the number of elective cataract surgeries. A retrospective single-center consecutive case series study was performed. We included all 12,464 patients who received cataract surgery in the period between 1 January 2016 and 31 May 2021. Monthly numbers of cataract surgeries during the pandemic were compared with monthly numbers in the reference years 2016–2019. In the pandemic the number of cataract surgeries decreased by 53.4%. The monthly numbers during the first, second and third wave of the pandemic were 77.5%, 51.5% and 29.7% lower, respectively, compared with the reference level. No rebound effect was observed once the pandemic restrictions were eased. Simultaneous bilateral cataract surgeries (SBCS) constituted 6.5% of cataract procedures performed in April and May 2021 compared with 0.77% carried out between May 2019 and March 2021. While the pandemic-affected monthly numbers of cataract surgeries tend to increase recently, they are still below the prepandemic level. Patients should be encouraged to weigh the risks of COVID-19-related morbidity and mortality against the benefits of cataract surgery. Reorganization of the logistics of cataract services is advisable with consideration of SBCS as one of the options.
