Impact of the SARS-CoV-2 pandemic on ophthalmic care in Germany

Epidemiology and Treatment of Patients With Primary Open Angle Glaucoma in Germany: A Health Claims Data Analysis

PRCIS

Based on a large administrative database of German claims data, our study provides current estimates of the prevalence and incidence of primary open angle glaucoma (POAG) in Germany and describes selected outcomes for prevalent patients with POAG.

PURPOSE

To estimate the prevalence and incidence of POAG in Germany, to describe the patient population in terms of comorbidity burden, routine care, and overall healthcare resource utilization (HCRU) and associated costs, and to describe treatment patterns over time in patients undergoing relevant laser procedures.

MATERIALS AND METHODS

Based on anonymized German claims data, we carried out a retrospective, noninterventional study covering calendar years 2016-2021.

RESULTS

For the adult German population (≥18 y), we estimated a POAG 1-year prevalence of 1.70% and a 1-year incidence of 0.17% in 2018; both increased with age, peaking in 80- to 89-year-olds. Prevalence and incidence were lower in 2020 (1.65% and 0.16%, respectively), the first year of the SARS-CoV-2 pandemic. Most patients solely received topical treatment. Most surgically treated patients underwent laser trabeculoplasty, followed by laser iridotomy, trabeculectomy, and filtration operations with implant. In patients undergoing laser trabeculoplasty, the treatment regimen was nearly unchanged in the second year after, compared with 2 years before the procedure. Multimorbidity was commonly observed; 75.5% of patients had arterial hypertension and 50.0% had disorders of lipoprotein metabolism and other lipidemias, compared with 60.1% and 39.2%, respectively, in an age- and sex-matched control sample.

CONCLUSIONS

Our study provides insights into epidemiology and routine care of POAG in Germany and HCRU in prevalent patients. There was little change in treatment regimens in patients who underwent laser trabeculoplasty, 2 years after the procedure. Most patients were multimorbid highlighting the need for comprehensive care.

Trends in the Clinical Presentation of Uveal Melanoma During the COVID-19 Pandemic

BACKGROUND AND OBJECTIVE

The objective was to evaluate factors associated with clinical presentation of uveal melanoma (UM) during the initial two years of the coronavirus disease 2019 pandemic.

PATIENTS AND METHODS

This was a multi-site, retrospective cohort study of patients treated for uveal melanoma during the first (early) and second (late) year of the pandemic compared with the year prior (control).

RESULTS

A total of 48, 67, and 75 patients were in the control, early, and late cohorts, respectively. The early cohort had a higher frequency of large tumors (control: 29.2%, early: 40.3%, late: 29.3%; P < 0.001) at presentation. Both the early and late cohorts had higher rates of enucleation (control: 8.33%, early: 20.9%, late: 18.67%; P ≤ 0.0338) compared to the control cohort.

CONCLUSIONS

While there was an increase in large tumors along with a rise in enucleation during the first year of the pandemic, enucleation rates remained elevated even while tumor sizes normalized. [Ophthalmic Surg Lasers Imaging Retina 2024;55:278-284.].

Surgical Care in Specialist Ophthalmology Departments: Structure and Impact of the COVID-19 Pandemic

BACKGROUND

Specialist ophthalmology departments contribute to the surgical care of German patients. Outpatient and inpatient surgeries were restricted during the COVID-19 pandemic and led to a sharp decline in the number of cases in ophthalmological care. The aim of this analysis was to improve the understanding of the logistic structures of medical facilities as well as the effects of the pandemic.

MATERIAL AND METHOD

Based on reported process data, a sample of the specialist ophthalmological departments were examined based on operation and procedure codes (OPS) and data submitted between 01.01.2017 and 31.05.2021 according to the benchmarking programmes of the Professional Association of German Anaesthetists (BDA), the Professional Association of German Surgeons (BDC), and the Association for Operating Theatre Management (VOPM).

RESULTS

Eighteen ophthalmology departments from Germany were analysed. After the decline in the number of cases (by temporarily up to 48%) during the first wave of the pandemic, the case numbers of all interventions assessed as nonurgent continued to be reduced. While intravitreal injections hardly decreased during the first wave (- 16%), significant drops in the coverage of cataract surgery (- 79%), vitrectomies (- 35%), glaucoma surgery (- 59%), strabismus surgery (- 95%), and eyelid surgery (- 52%) were found. One exception was intravitreal injection, which stabilised at a lower level early on during the pandemic. Overall, the number of cases during the later phases of the pandemic were significantly reduced below the level of previous years, despite the maintenance of emergency care. The underuse was variable for different interventions.

CONCLUSION

In addition to self-reported figures, the analysed process data demonstrates the effect that various factors had on elective as well as urgent operations within hospital care during the pandemic. Despite partial stabilisation of some services, a relevant supply gap for outpatient and inpatient interventions was identified, with corresponding effects on the eye health of the population, while compensation or performance enhancement have not taken place to date. Facing the growing preload and the demographic development, future structures must therefore allow for an increase in the performance of specialist ophthalmological departments.

Retinal Vascular Occlusion after COVID-19 Vaccination: More Coincidence than Causal Relationship? Data from a Retrospective Multicentre Study

Background: To investigate whether vaccination against SARS-CoV-2 is associated with the onset of retinal vascular occlusive disease (RVOD). Methods: In this multicentre study, data from patients with central and branch retinal vein occlusion (CRVO and BRVO), central and branch retinal artery occlusion (CRAO and BRAO), and anterior ischaemic optic neuropathy (AION) were retrospectively collected during a 2-month index period (1 June–31 July 2021) according to a defined protocol. The relation to any previous vaccination was documented for the consecutive case series. Numbers of RVOD and COVID-19 vaccination were investigated in a case-by-case analysis. A case–control study using age- and sex-matched controls from the general population (study participants from the Gutenberg Health Study) and an adjusted conditional logistic regression analysis was conducted. Results: Four hundred and twenty-one subjects presenting during the index period (61 days) were enrolled: one hundred and twenty-one patients with CRVO, seventy-five with BRVO, fifty-six with CRAO, sixty-five with BRAO, and one hundred and four with AION. Three hundred and thirty-two (78.9%) patients had been vaccinated before the onset of RVOD. The vaccines given were BNT162b2/BioNTech/Pfizer (n = 221), followed by ChadOx1/AstraZeneca (n = 57), mRNA-1273/Moderna (n = 21), and Ad26.COV2.S/Johnson & Johnson (n = 11; unknown n = 22). Our case–control analysis integrating population-based data from the GHS yielded no evidence of an increased risk after COVID-19 vaccination (OR = 0.93; 95% CI: 0.60–1.45, p = 0.75) in connection with a vaccination within a 4-week window. Conclusions: To date, there has been no evidence of any association between SARS-CoV-2 vaccination and a higher RVOD risk.

Patients' Perception of COVID-19 Preventive Measures in Ophthalmology: Satisfaction and Impact on Glaucoma Care and Follow-up

PURPOSE

In response to the spread of COVID-19 in Switzerland, ophthalmology practices implemented a variety of preventive measures in order to minimise the risk of contamination to their patients and staff. Yet, some studies suggested that over a quarter of all glaucoma patients never returned to the clinic after the first lockdown eased. This raises the question of the factors influencing Patients' likelihood to keep their appointments in this COVID-19 era. The aim of this study was therefore to assess ophthalmology Patients' perception of COVID-19 preventive measures, as well as their impact on glaucoma Patients' clinic attendance and follow-up.

METHODS

This was a prospective study based on primary data collected from 12 private ophthalmology clinics in French-speaking Switzerland. A web-based patient experience questionnaire was designed to assess Patients' appreciation of the preventive measures in place at their eye care provider as well as their intention to attend further follow-up appointments. These measures were made on modified 10-point Likert scales. Every patient who attended an appointment at one of the participating clinics on randomly selected dates in October 2020 was offered voluntary enrolment into the study.

RESULTS

In all, 118 surveys were completed and analysed. The mean age of respondents was 57.8 ± 18.0 years, 59.3% were female, and 71.2% were Swiss nationals. Fifty-four (45.8%) of them suffered from glaucoma. Overall, patients were highly satisfied with the measures in place to safeguard them from COVID-19 infection, with a mean score of 9.29 ± 1.35. This was higher amongst Swiss nationals (9.55 ± 0.77) than foreigners (8.65 ± 2.09). On average, responders expressed a 90.2 ± 17.5 percent likelihood to keep their follow-up appointment. The figure went down to 88.5 ± 19.9 percent amongst glaucoma patients (p = 0.58), and 86.3 ± 22.1 percent amongst glaucoma patients aged 65 and over (p = 0.29). Interestingly, older glaucoma Patients' satisfaction with preventive measures in place strongly correlated with their likelihood to keep follow-up appointments (r = 0.72). The correlation was moderate amongst all glaucoma patients (r = 0.46) and weak amongst all respondents (r = 0.38) and those over 65 (r = 0.44).

CONCLUSIONS

The present research highlights the importance of Patients' perception on COVID-19 preventive measures in place in ophthalmology clinics, which was directly associated with their likelihood to keep follow-up appointments. Vulnerable subgroups of patients were more likely to miss their follow-up appointments altogether, and their decision to attend was more strongly influenced by their perceived risk of contracting COVID-19. This suggests a role for telemedicine in more vulnerable patients suffering from progressive diseases such as glaucoma.

Public perceptions of eye symptoms and hospital services during the first UK lockdown of the COVID-19 pandemic: a web survey study

Objective

This study aimed to explore the British public’s healthcare-seeking beliefs concerning eye symptoms, and assess how the first COVID-19 lockdown influenced these.

Methods and analysis

An anonymous web-based survey was disseminated through mailing lists and social media between June and August 2020. The survey sought participants’ views on the severity and urgency of the need for medical review for four ophthalmic and two general medical scenarios on a five-point scale. Participants were asked to answer questions twice: once ignoring the COVID-19 pandemic, and once taking this into account, with additional questions asked to identify factors influencing the decision to seek medical attention and ward admission.

Results

A total of 402 participants completed the survey (mean age 61.6 years, 63.1% female and 87.7% of white ethnicity). Scores for symptom severity and urgency of medical review increased significantly with the severity of the clinical scenario (both p<0.001). However, participants gave significantly lower scores for the urgency of medical attention when accounting for the COVID-19 pandemic (compared with no pandemic) for all scenarios (all p<0.001). Younger age, greater deprivation and non-white ethnicity were correlated with a lower perception of seriousness and urgency of medical attention.

Conclusions

During the first UK lockdown of the COVID-19 pandemic, reduced urgency of medical review for ocular and systemic pathologies was reported in response to the pandemic, which represents a barrier to healthcare-seeking behaviour. This has the potential to critically delay medical review and timely management, negatively impacting patient outcomes.

The effect of COVID-19 pandemic on the attendance and clinical outcomes of patients with ophthalmic disease: A mini-review

The outbreak of COVID-19 was followed by a rapid spread leading to its declaration as a pandemic in a short time. The transmission through aerosols and direct contact with infected individuals forced the application of strict safety protocols and rearrangements in the activities of different healthcare systems around the world. Ophthalmology healthcare workers are highly exposed to viral infection and therefore adjustments were made to ensure the safety of patients and health providers by performing only urgent treatments. The suspension and delay in regular follow-up visits and the lower number of patients recorded during the lockdown period due to restrictions and patient anxiety led to severe consequences in the clinical and anatomical outcome affecting the overall prognosis. The current review aims to summarize the effect of the lockdown policies in the number and profile of patients that attended the ophthalmology clinics from different countries and analyze the effect of the pandemic in terms of vision and patient functionality. The effects of the pandemic included a reduction in the number of appointments, cancellations of non-emergency conditions and delays of surgical interventions. These had a negative effect in terms of visual outcomes.
