Emotional and physical experiences of people with neovascular age-related macular degeneration during the injection process in Germany: a qualitative study

OBJECTIVES

In order to better understand the continued barriers to the provision of vascular endothelial inhibitor therapy, this study aims to investigate patients' experiences with neovascular age-related macular degeneration (nvAMD) in Germany during the injection process and how they deal with it.

DESIGN AND PARTICIPANTS

This analysis is part of the qualitative arm of a wider mixed-methods study. We recruited participants all over Germany via ophthalmologists, eye clinics, general practitioners, care bases and support groups between June 2018 and December 2020 and selected a subsample of study participants with nvAMD who were either undergoing or had previously undergone vascular endothelial growth factor inhibitor therapy. We conducted narrative, semistructured, face-to-face interviews at the participants' homes, which were audio-recorded. The interviews were thematically analysed.

RESULTS

Twenty-two participants were included in this analysis. Experiencing neovascular macular degeneration was dominated by the injection experience. Study participants perceived the treatment with vascular endothelial inhibitor injections as uncomfortable, and they described undergoing varying levels of anxiety during the whole injection process. After some years of receiving multiple injections, the pain and not experiencing any positive effects made participants with significant vision loss want to discontinue therapy. Furthermore, they narrated negative injection experiences in association with their interactions with medical staff and doctors.

CONCLUSION

Although time in the medical setting is limited, efficient and good doctor-patient relationships seem crucial for satisfying care experiences. A respectful and humane relationship may be one key to achieving treatment adherence.

[Impact of a more stringent organization of intravitreal injection treatment on the number of treatments and examinations in routine practice]

BACKGROUND

Results from recent studies show that less intravitreal injections are often performed in everyday practice than in controlled trials, which subsequently leads to worse treatment success. In this study we analyzed the introduction of a more stringent organization of treatment using workflow optimization and new IT systems and analyzed the effect on treatment continuity.

MATERIAL AND METHODS

In the second quarter of 2019 a new medical practice management software and a software for automated injection planning were implemented. There was also a change of the treatment regimen from pro re nata (PRN) to treat and extend (T&E ). We analyzed the results of the patients regarding the frequency of injections and treatment controls three quarters before (Q3/2018-Q1/2019) and three quarters after the change (Q2/2019-Q4/2019). Treatment-naive and pretreated patients were analyzed.

RESULTS

In group 1 (Q3/2018-Q1/2019) the average number of injections per quarter was 1.74 (SD = 0.4). Eyes of patients from group 2 (Q2/2019-Q4/2019) received on average 2.17 (SD = 0.3) injections. The number of check-ups per quarter was 1.71 (SD = 0.3) before the introduction, and thereafter 2.16 (SD = 0.3). There was a significant increase in the number of OCTs from 1.18 (SD = 0.2) to 1.98 (SD = 0.3). The visual acuity was stable in both groups.

CONCLUSION

We were able to show that the introduction of the medical practice management software and the change of the regimen from PRN to T&E can achieve numbers of injections, check-ups and OCT similar to those in studies. A standardized procedure facilitates efficient treatment planning and enables a better patient management.

[IVOM quality assurance in Westfalen-Lippe : Structure of quality assurance and results of the pilot study Q-VERA]

BACKGROUND

The KVWL-QS assists ophthalmologists in the transfer for good clinical praxis into real life. In addition the QS-commission initiated a pilotstudy "Qualitäts-Versorgung bei AMD" (Q‑VERA) in order to test new instruments for improvements. It was analized, if Reading Center (RC) based controls in combination with specific case-management modules can improve the results of IVOM treatment.

PATIENTS AND METHODS

In 5 treatment centers 878 consecutive patients with newly diagnosed AMD (Neu-Patienten) were included, who were treated with the IVAN-scheme. Initial FA and OCT images were transferred electronically to the RC. Also 781 retreatment patients (mean 20.7 IVOM before) with retreatment due to lesion activity were observed.

RESULTS

In 5% of the 878 newly treated patients a discrepancy between RC and treatment center was recorded. In this group the 481 patients, who finished up to the analysis date the 12-month follow-up, the visual function (increase in BCVA) and SD-OCT (reduction in central retinal thickness) results were comparable with large prospective cohorts. This was achieved with 6.5 injections and 10.6 visits over 12 months. In the group of 781 patients with repeated injections the number of injections over 12 months was 7.7 and the number of visits 11.6.

CONCLUSION

Quality assessment can improve the efficacy of IVOM therapy for AMD patients in real life. In addition to existing structures, electronical exchange by a RC assisted evaluation can further improve the quality by reducing the number of unnecessary treatment visits. The case-management with adherence control, re-call-system and specific information for patients and relatives can specifically increase the long-term adherence and thus the success of the therapy.
