J Patient Rep Outcomes 2024; 8:89. [PMID: 39133415 PMCID: PMC11319536 DOI: 10.1186/s41687-024-00775-z] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/09/2023] [Accepted: 08/05/2024] [Indexed: 08/13/2024] Open
Abstract
BACKGROUND Neovascular age-related macular degeneration (nAMD) is a common cause of visual impairment and blindness in the elderly with globally increasing prevalence. Vascular endothelial growth factor inhibitor (anti-VEGF) treatment has improved visual prognosis of nAMD, but continuous treatment may cause anxiety and stress, although increase in visual acuity (VA) may also have positive effects on patients' quality of life. The health care burden due to frequent treatment and monitoring is apparent, but the effect of anti-VEGF treatment on patients' quality of life is not fully understood. We evaluated the overall impact of nAMD and its treatment on newly diagnosed patients' health-related quality of life (HRQoL) in real-world setting. METHODS The present prospective cohort study included newly diagnosed nAMD patients treated with anti-VEGF injections at Oulu University Hospital during 2019-2020. Data included parameters from comprehensive ophthalmic examination and fundus imaging, age at diagnosis, sex, comorbidities, visual acuity, and frequency of anti-VEGF injections. HRQoL was assessed by 15D questionnaire at diagnosis, 6 months, and 12 months. RESULTS 95 nAMD patients were included. They were 78 ± 8 years old, 56 (59%) were female, and 74 (78%) had more than one comorbidity. The patients received 8 ± 3 anti-VEGF-injections. Visual acuity (VA) improved from 56 ± 18 to 61 ± 24 Early treatment diabetic retinopathy study (ETDRS) letters in 12 months. VA improved > 5 ETDRS letters in 45 (47%), remained stable in 30 (32%) and decreased > 5 letters in 17 (18%) eyes. The mean total 15D score reflecting overall HRQoL decreased from 0.850 ± 0.104 to 0.834 ± 0.103 in 12 months. Decreased HRQoL was associated with baseline best-corrected VA (BCVA) ≥ 70 ETDRS letters (p = 0.023) and more than one comorbidity (p = 0.034). HRQoL regarding visual function increased from 0.765 ± 0.194 to 0.789 ± 0.184 during the 12-month follow-up. CONCLUSIONS In real world setting, HRQoL regarding visual function improved in anti-VEGF-treated nAMD patients during the first 12 months after the diagnosis and treatment initiation. Good baseline VA or several comorbidities were associated with decreased overall HRQoL during the follow-up. Despite the effectiveness of anti-VEGF treatment on visual function, several other aspects affecting elderly patients' everyday life should be considered when nAMD treatment is implemented.

The management of neovascular age-related macular degeneration: A systematic literature review of patient-reported outcomes, patient mental health and caregiver burden. Acta Ophthalmol 2023; 101:e26-e42. [PMID: 35790079 PMCID: PMC10084380 DOI: 10.1111/aos.15201] [Citation(s) in RCA: 4] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2022] [Revised: 05/27/2022] [Accepted: 05/31/2022] [Indexed: 01/25/2023]
Abstract
PURPOSE The aim of this systematic literature review was to describe patient-reported outcomes, mental health and caregiver burden in patients with neovascular age-related macular degeneration (nAMD) treated with anti-vascular endothelial growth factor (VEGF) agents in routine clinical practice. METHODS Electronic searches were conducted in Embase and MEDLINE according to pre-defined criteria. RESULTS Of 856 records identified, 63 met inclusion criteria. Depression or depressive symptoms were reported in up to 42% of patients with nAMD. Of 25/63 (40%) studies evaluating quality of life (QoL) and using various tools, eight studies reported composite National Eye Institute Visual Functioning Questionnaire scores following anti-VEGF treatment. Of these, seven reported a statistically significant improvement at the earliest time point measured (Month 3-12) and approximately 50% reported sustained QoL benefits at 12 months. In studies comparing the attributed or different regimens, the most important factor from the patient's perspective was the likelihood that a particular regimen would maintain vision. There was a preference towards treat and extend, which was associated with a perceived reduction in patient and caregiver burden, compared to fixed dosing. CONCLUSIONS A coordinated holistic approach to patient care is key to optimizing patient well-being as well as visual outcomes. Further research regarding the patient-reported impact of nAMD management outside the trial setting (particularly international longitudinal studies) is warranted. Standardization of QoL studies would assist in establishing whether sustained QoL improvement, rather than prevention of QoL decline, should be a realistic expectation of treatment of nAMD in the longer term.

Wang A, Rand K, Yang Z, Brooks R, Busschbach J. The remarkably frequent use of EQ-5D in non-economic research. THE EUROPEAN JOURNAL OF HEALTH ECONOMICS : HEPAC : HEALTH ECONOMICS IN PREVENTION AND CARE 2022; 23:1007-1014. [PMID: 34846623 PMCID: PMC9304056 DOI: 10.1007/s10198-021-01411-z] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 01/26/2021] [Accepted: 11/11/2021] [Indexed: 05/14/2023]
Abstract
INTRODUCTION EQ-5D is an instrument which has been utilized for a variety of purposes, including in health-economic appraisals as an input into quality-adjusted life year (QALY) calculations. Indeed, it is the most-widely applied instrument for health-economic appraisal worldwide, and is recommended for use in QALY calculations by many national Health Technology Assessment (HTA) agencies. There is also a growing body of evidence for its usefulness in a variety of settings other than economic appraisals, but such use has not been well-documented. This study addresses this issue and documents how EQ-5D has been applied in both the non-economic and economic contexts. METHODS The PubMed database was searched using the terms 'EQ-5D', 'EQ-5D AND cost', and 'EQ-5D AND cost AND QALY' from 1 January 1980 to 31 December 2019. We concentrated on 2019 publications for more detailed analyses. All the data collected for 2019 were downloaded and collected in EndNote. For 2019 only, we classified economic and non-economic use based on the inclusion of 'cost'. We also checked by manual inspection whether the search terms were suitable in correctly identifying economic and non-economic use. Variants of the non-economic use of EQ-5D were classified as follows: (a) as a quality of life outcome measure; (b) as a tool for methodological research; (c) methodological issues of EQ-5D itself; (d) comparisons with other quality of life questionnaires; (e) mapping studies; (f) value sets; (g) alongside costs but no QALY calculated; and (h) other. RESULTS The first publication found was from 1990. Up to and including 2019, 10,817 publications were identified, of which more than two in three did not contain any reference to costs or QALYs. In 2019, a total of 1409 manuscripts were identified, of which 239 were specifically for EQ-5D-5L. Four hundred and seven (28.9%) included some form of 'costs' and 157 (11.1%) both 'costs' AND 'QALYs' terms. For EQ-5D-5L, the corresponding numbers were 104 (43.5%) and 29 (12.1%), respectively. After manually checking all the 1409 papers, three were duplicated records, which were omitted. In the remaining 1406 papers, only 40 (2.8%) contained the term 'cost', but not 'cost per QALY', and only 117 (8.3%) were identifiable as economic evaluations using the term 'cost per QALY'. Most non-economic use of EQ-5D was as a quality-of-life outcome measure (72.8%). Other applications were: as a tool for methodological research (6.7%); comparison studies (3.7%); EQ-5D methodological issues (3.5%); containing costs but not QALYs (2.8%); mapping (1.3%); value sets (0.4%); and other papers (0.4%). CONCLUSIONS The majority of the studies retrieved, covering a wide variety of research areas, reported upon the non-economic use of EQ-5D. Despite being the most-used instrument worldwide for QALY calculations, economic appraisal accounted for only a small, but important, part of published use.

Drop in well-being of ARMD patients under treatment with anti-VEGF injections during the COVID-19 pandemic. Int Ophthalmol 2022; 42:2493-2499. [PMID: 35362811 PMCID: PMC8972774 DOI: 10.1007/s10792-022-02296-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2021] [Accepted: 03/10/2022] [Indexed: 11/15/2022]
Abstract
Purpose Patients with age-related macular degeneration (ARMD) are required to follow a treatment protocol that requires regular follow-ups. The COVID-19 pandemic has created an additional burden for patients with ARMD under treatment with anti-vascular endothelial growth factor (anti-VEGF) injections, since patients face a congestion of the health system and closing of the outpatient services. This study examines the impact of the uncertainty regarding patients’ treatment on their sense of well-being.
Methods This is a longitudinal cohort study of eighty patients who were followed during the year following the outbreak of the COVID pandemic. Patients reported their sense of well-being with the WHO-5 questionnaire and their perception and fears for the impact of the pandemic on their ongoing ARMD treatment. Results There was a significant drop in mental well-being during the pandemic that paralleled the self-reported impact of the pandemic on ARMD treatment. Patients who reported a higher impact of COVID-19 on their treatment had experienced a higher drop in mental wellbeing compared to those who hadn’t, with female gender being an additional risk factor. Objective measurements of visual acuity did not factor in the drop of sense of well-being. Conclusions The high initial level of uncertainty regarding ARMD patients’ long-term course was further exacerbated when exposed to additional uncertainties during the pandemic regarding their standard of care. Planning ahead for continuation of services and close contact with patients during similar health emergencies is of paramount importance.

[PMID: 34483815 PMCID: PMC8414246 DOI: 10.3389/fnins.2021.663062] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/02/2021] [Accepted: 07/23/2021] [Indexed: 11/13/2022] Open
Abstract
Purpose: Investigating difficulties during activities of daily living is a fundamental first step for the development of vision-related intervention and rehabilitation strategies. One way to do this is through visual impairment simulations. The aim of this review is to synthesize and assess the types of simulation methods that have been used to simulate age-related macular degeneration (AMD) in normally sighted participants, during activities of daily living (e.g., reading, cleaning, and cooking). Methods: We conducted a systematic literature search in five databases and a critical analysis of the advantages and disadvantages of various AMD simulation methods (following PRISMA guidelines). The review focuses on the suitability of each method for investigating activities of daily living, an assessment of clinical validation procedures, and an evaluation of the adaptation periods for participants. Results: Nineteen studies met the criteria for inclusion. Contact lenses, computer manipulations, gaze contingent displays, and simulation glasses were the main forms of AMD simulation identified. The use of validation and adaptation procedures were reported in approximately two-thirds and half of studies, respectively. Conclusions: Synthesis of the methodology demonstrated that the choice of simulation has been, and should continue to be, guided by the nature of the study. While simulations may never completely replicate vision loss experienced during AMD, consistency in simulation methodology is critical for generating realistic behavioral responses under vision impairment simulation and limiting the influence of confounding factors. Researchers could also come to a consensus regarding the length and form of adaptation by exploring what is an adequate amount of time and type of training required to acclimatize participants to vision impairment simulations.

Abstract
To compare the visual performance of a monofocal intraocular lens (IOL) (ZCB00) and a multifocal IOL (ZMB00) of the same material and basic design, we evaluated postoperative parameters at 10 weeks after the last surgery in cataract patients who underwent bilateral ZCB00 or ZMB00 implantation from December 13, 2010, to July 29, 2019, with the right and left lenses implanted within 3 months of each other. The study enrolled 2,230 eyes of 1,115 patients. The monofocal group comprised 904 eyes of 452 patients (72.3 ± 6.8 years; females/males, 268/184), and the multifocal group comprised 1,326 eyes of 663 patients (67.0 ± 7.8 years; females/males, 518/145). Contrast sensitivity (4.0/2.5/1.6/1.0/0.7 degrees), contrast sensitivity with glare (1.6/1.0/0.7 degrees), and the VFQ-25 score for driving at night were significantly better in the monofocal group (p < 0.00068, Wald test). Uncorrected intermediate/near visual acuity and near spectacle independence were significantly better in the multifocal group (p < 0.00068, Wald test). The two IOL groups had different characteristics in terms of contrast sensitivity, night-time driving, uncorrected intermediate/near visual acuity and near spectacle independence.
