Retinal Prostheses in the Medicare Population[Entered Retrospectively].

Project Summary Title and Description

Retinal Prostheses in the Medicare Population[Entered Retrospectively].
To determine the safety, efficacy, and evidence for halting disease progression for retinal prosthesis systems (RPSs) and the outcomes that are and could be assessed in future studies of these devices.
Authors of Report
Methodology description
We searched Medline, EMBASE, Cumulative Index to Nursing and Allied Health (CINAHL), the Cochrane Library, PubMed (unprocessed records only), and gray literature sources, including conference proceedings from specialty societies, for studies of RPS devices published from January 1, 2000, through April 25, 2016.We performed redundant title and abstract screening with one reviewer’s selection required for full-text article retrieval. Dual independent review was performed on all full-text articles, with disagreements resolved by consensus. Data extraction was performed by a single reviewer and was fully verified by a second reviewer. Extracted data included study design, psychometric properties assessment methods based on the COSMIN checklist, patient blinding to experimental condition, outcome assessor blinding to experimental condition, experimental condition randomly presented, number of outcome assessors, country/site, number of patients enrolled, patient inclusion criteria, patient exclusion criteria, RPS treatment details, prior treatment, concurrent treatment, study duration, diagnosis, age at diagnosis, age at implantation, eye implanted, time from implantation to study participation, sex, race, visual acuity at time of implantation, outcomes, and outcome definitions. We assessed risk of bias of individual studies for the outcomes of interest, and graded the overall strength of evidence using Evidence-based Practice Centers guidance.
Data entered retrospectively by uploading a file with both efficacy and adverse event outcomes.

Key Questions

1. KQ1A: What outcome measures have been used in studies of RPSs?
2. KQ1B: What are the psychometric properties of the health-related quality of life (HRQoL), ability to perform activities of daily living (ADLs) and instrumental activities of daily living (IADLs), visual function, and other measures used in the studies?
3. KQ1C: What other reliable and valid measures could be used in future studies of RPSs to demonstrate improvement in HRQoL, ability to perform ADLs and IADLs, visual function, and other functions?
4. KQ2: What is the evidence that HRQoL, ability to perform ADLs and IADLs, visual function, and other outcomes are improved in patients who use an RPS compared with baseline (or device OFF or untreated eye) and compared with alternative treatments?
5. KQ3: What is the evidence that the use of RPS arrests the progression of RP?
6. KQ4: What is the evidence on adverse events associated with the use of RPS?
7. KQ5A: What is the evidence on off-label use of RPS?
8. KQ5B: From a narrative review of the literature, are other uses suggested for RPS?
