Takeaway Factors
Diabetic retinopathy (DR) is a number one explanation for blindness and visible impairment in the US. Screening is essential for stopping imaginative and prescient loss and is increasing to main care and different settings. We describe the design and implementation of a main care–based mostly DR screening program, with a deal with well being info know-how (IT) concerns.
Diabetes is a worldwide epidemic and is related to a number of issues.1-4 One devastating complication is diabetic retinopathy (DR), which in the US is the main explanation for blindness and visible impairment amongst working-age adults.5,6 As a result of imaginative and prescient loss might be prevented with early detection and remedy, DR screening is a public well being precedence and has been included into high quality measures such because the Benefit-based Incentive Fee System (MIPS).7-9
DR screening packages in medical and community-based settings have demonstrated feasibility, accuracy, and cost-effectiveness.10-14 The present literature on telemedicine approaches for DR screening largely focuses on referral patterns to ascertain the continued want for screening.15-17 Current advances in synthetic intelligence (AI) have additionally enabled automated prognosis of DR, an space of lively analysis investigation.18-23
Nonetheless, the literature on utilized informatics associated to DR screening is scarce. Scanlon et al24 described an automatic information extraction course of from normal practitioners’ digital well being data (EHRs) to routinely replace DR screening lists, which discovered sufferers who have been beforehand unidentified. One other research by Melles et al25 demonstrated that using a centralized digital studying heart (ie, a centralized group of ophthalmologists and optometrists decoding retinal photographs for a variety of medical websites) was related to improved screening accuracy. Nonetheless, prior research haven’t delved into the precise particulars of implementing DR screening packages from a well being info know-how (IT) perspective nor examined challenges associated to integrating these packages with present medical info programs and workflows intimately.
Right here, we describe our expertise creating and implementing medical informatics instruments supporting a brand new main care–based mostly “teleretina” DR screening program. Our goals have been (1) to design a workflow for bettering DR screening charges, (2) to develop instruments facilitating integration of this workflow with present medical info programs, and (3) to have interaction related stakeholders and replicate on classes discovered to tell future enhancements.
METHODS
Research Setting
This research was performed on the College of California San Diego (UCSD), an instructional medical heart in San Diego County. Retinal cameras have been put in at 3 main care (inner medication and household medication) clinics. The research adhered to the Declaration of Helsinki and was authorized by the UCSD Institutional Overview Board as a top quality enchancment protocol.
Wants Evaluation
Previous to program implementation, solely about half (47%) of sufferers with diabetes at our establishment had documented eye exams. As a result of in-person eye clinic examinations weren’t assembly high quality metric objectives, the necessity to develop screening to main care websites (teleretina DR screening) was recognized.
First, we performed an in depth examination of the present workflows for in-person DR screening by interviewing main care physicians, eye clinic management, ophthalmologists, optometrists, and scheduling personnel. We recognized care gaps to formulate a wants evaluation, which knowledgeable the design of the brand new main care–based mostly screening program.
The framework of the brand new program entailed retinal imaging at main care clinics, asynchronous picture interpretation by ophthalmologists or optometrists (“eye care suppliers”), automated notification of main care physicians (PCPs) concerning screening outcomes, and subsequent care coordination. Major care–based mostly imaging would lower the necessity for in-person eye examinations. Eligible sufferers consisted of adults (≥ 18 years) with a prognosis of diabetes (any kind) who lacked a documented eye examination inside the prior 12 months, with out preexisting ophthalmic diagnoses or lively imaginative and prescient complaints.
Design Targets for Informatics Instruments
First, we aimed to combine screening photographs with the present eye clinic image and archiving communication system (PACS) (ZEISS Discussion board; Carl Zeiss Meditec AG). Subsequently, retinal photographs acquired in main care could be uploaded to the identical PACS, permitting eye care suppliers to view these photographs alongside sufferers’ prior ophthalmic imaging/testing.
Primarily based on prior literature concerning the time and cognitive burden of well being IT on well being care suppliers,26-29 one other design aim was to combine the brand new workflow with the present institutional EHR system (Epic Programs) and incorporate automation to cut back the effort and time required by finish customers. Particularly, we aimed to develop automated completion of billing and high quality metric reporting through the “well being upkeep matter” in Epic, a performance to doc and monitor completion of preventive well being and high quality measures.
One other design aim centered on facilitating the benefit of discovering sufferers who required imaging interpretations, coming into imaging interpretations, and notifying PCPs of outcomes. At UCSD, main care employees utilized Epic’s Ambulatory module, whereas eye care suppliers utilized Epic’s Kaleidoscope module. Every module has totally different instruments for ordering, examination interpretation, and outcome notification. Our aim was to combine each modules whereas guaranteeing that customers from each areas have been nonetheless working in acquainted EHR screens. We aimed to develop an EHR-integrated report to simply monitor the standing of imaging exams and to facilitate interpretation completion whereas minimizing clicks and navigational steps.
Implementation Processes
Preimplementation phases included workflow design, tools set up, and coaching actions. Major care employees have been educated concerning the rationale of the brand new DR screening program, affected person eligibility standards, digital camera use and picture acquisition, and particulars of the brand new workflow inside the PACS and EHR. This coaching was performed through dwell/synchronous coaching classes with this system management crew, together with a PCP lead and a nurse supervisor, and supplemented with written supplies that have been distributed to every screening web site and posted on inner institutional web sites. Coaching on digital camera use and picture acquisition was supplied by the digital camera vendor (Optos Inc) by way of in-person, hands-on coaching classes previous to implementation. A digital camera vendor consultant was additionally out there through e-mail and videoconference conferences to handle extra questions.
Testing was carried out to make sure profitable integration of main care photographs with the attention PACS in addition to profitable automated completion of billing/cost seize and the well being upkeep matter upon imaging interpretation entry. Coaching of eye care suppliers was performed to orient them to the teleretina imaging report and to the customized picture interpretation entry software. Three check affected person charts, which have been out there in a “play” surroundings supplied by the institutional EHR vendor, have been used to make sure profitable execution of the workflow previous to implementation within the manufacturing surroundings.
At go-live, on-site help was supplied to the first care clinics that have been buying retinal photographs by informatics analysts, the PCP lead, and the nurse supervisor, who have been bodily current on the day of go-live and out there to reply any questions from main care employees as they entered orders, imaged sufferers, and uploaded photographs. Informatics help from the analysts was additionally out there to eye care suppliers studying photographs. This included synchronous videoconference conferences to handle questions concerning the picture interpretation course of and asynchronous help through e-mail. Eye care suppliers have been anticipated to learn photographs every weekday and supply interpretations inside 72 hours of picture acquisition. Night time/weekend protection was not essential as a result of this was a screening program for asymptomatic people with out recognized ocular diagnoses and never a venue for evaluating ocular emergencies.
Weekly stakeholder conferences have been performed preimplementation (for six months previous to go-live) and for two weeks after go-live. Thereafter, conferences have been performed month-to-month to evaluate final result metrics (see beneath) and spotlight alternatives for ongoing enchancment. Stakeholder teams represented at these conferences included main care, endocrinology, ophthalmology, optometry, medical informatics, EHR analysts/info companies, imaging IT specialists, the digital camera vendor, the UCSD High quality Division, and the UCSD Inhabitants Well being Providers Group (PHSO).
Final result Evaluations
A predefined aim was specified as 4% enchancment within the MIPS “diabetic eye examination” high quality measure by June 30, 2021. Every month after go-live (October 12, 2020), reporting was accomplished concerning the variety of photographs acquired, proportion of poor-quality photographs, and efficiency on the institutional diabetic eye examination metric. For this research we analyzed information from October 2020 to July 2021. We generated descriptive statistics of longitudinal traits utilizing Microsoft Excel (Microsoft Company). We additionally recognized well being IT challenges that arose and qualitatively described options that have been developed.
RESULTS
Wants Evaluation
We examined present DR screening workflows involving in-person eye examinations. Sufferers have been recognized through a number of strategies: a pink “well being upkeep” alert within the EHR, evaluate of encounters by main care clinic employees throughout a “each day huddle,” and handbook chart evaluate. For these sufferers, PCPs positioned referral orders to eye care suppliers. Further sufferers needing screening have been recognized from the EHR and given bulk referral orders by the UCSD PHSO, the entity overseeing UCSD’s managed care inhabitants. Any sufferers with referral orders would obtain an automatic telephone name with a prerecorded message asking the affected person to schedule an eye fixed clinic appointment. As soon as scheduled, the affected person would go in particular person to the attention clinic and bear imaging and examination by an eye fixed care supplier, who would write a progress observe.
This workflow revealed a number of gaps (eAppendix Determine [available at ajmc.com]). First, sufferers may very well be misplaced to follow-up within the scheduling course of. The automated message asking the affected person to name and schedule their eye appointment required affected person proactivity, and moreover they could not have been conscious of the rationale for an eye fixed examination. Moreover, the attention clinic’s customary telephone triage algorithm included the query, “Do you want glasses?” If the affected person responded sure, they may very well be inappropriately scheduled for a refraction (ie, measured for glasses) quite than a dilated DR screening examination. A further barrier was that on the time of this program implementation, not all eye care suppliers at our establishment had adopted EHRs—some have been nonetheless documenting on paper. Thus, PCPs have been unable to simply discern the screening outcomes. Even for eye care suppliers utilizing the EHR, not all despatched referral letters speaking outcomes again to PCPs. Lastly, there was no present linkage to finish the EHR’s well being upkeep matter associated to diabetic eye exams. This required handbook completion, of which most eye care suppliers have been unaware.
We designed the brand new teleretina DR screening program (Determine 1) to fill a few of these gaps. Buying retinal imaging in main care clinics would scale back loss to follow-up and remove boundaries associated to time, transportation, and prices related to an in-person eye examination. As well as, a workflow built-in with the EHR would permit screening outcomes to be immediately seen to PCPs and routinely full well being upkeep documentation for institutional high quality metric reporting.
Informatics Instruments for the Major Care–Primarily based DR Screening Program
We achieved our design objectives with the next:
Integration with present ophthalmology viewing programs. Photographs acquired in main care have been efficiently built-in into the present eye PACS. This required acquisition of extra licenses and an in depth safety evaluate for brand new machine integration. Eye care suppliers have been in a position to view all eye photographs in a single PACS, whether or not acquired in eye clinics or in main care clinics.
Automated billing and cost seize. Expenses have been routinely entered upon signing the picture interpretation and have been routinely distributed between main care (technical charges) and ophthalmology (skilled charges) with out requiring end-user participation.
Automated completion of well being upkeep matter. Signing the picture interpretation routinely accomplished the EHR well being upkeep matter on diabetic eye exams with out requiring handbook completion. This characteristic was used not just for figuring out sufferers requiring DR screening but additionally for institutional high quality metrics reporting.
Report for monitoring screened sufferers. On this main care–based mostly screening program, the ordering suppliers have been PCPs from a number of clinics. To keep away from eye care suppliers having to manually search throughout imaging orders from a variety of PCPs, a customized report was created to mixture all teleretina DR screening orders (Determine 2).
Macros for standardizing imaging interpretation. We linked the screening report back to a custom-made picture interpretation window (Determine 3 [A]), which enabled (1) information entry while not having to open the affected person’s chart, (2) subsequent reporting of structured/discrete information components, and (3) the constructing of macros (a saved set of options) to facilitate interpretation completion. This window nonetheless generated a pure language observe (Determine 3 [B]) simply readable by PCPs.
Outcomes
A complete of 316 sufferers underwent main care–based mostly DR screening between October 12, 2020, and July 31, 2021. Month-to-month imaging quantity ranged from 17 (July 2021) to 46 (March 2021) (Determine 4 [A]). Of 316 sufferers screened, 58 (18.4%) had a minimum of 1 eye with inadequate picture high quality for interpretation. Month-to-month proportions of low-quality photographs ranged from 6.9% to 42.9% (Determine 4 [B]). Of screened sufferers, 73 (23.1%) had ocular pathology. Diagnoses included DR, glaucoma/glaucoma suspect, age-related macular degeneration, epiretinal membranes, optic nerve drusen, choroidal nevi, and chorioretinal scarring. Photographs of a affected person with beforehand undiagnosed DR recognized by way of this program are depicted in Determine 5.
Our institutional efficiency was 47% for the diabetic eye examination MIPS metric earlier than implementation of the first care–based mostly DR screening program. As of June 30, 2021, this system achieved 65% for the diabetic eye examination metric, exceeding the predefined aim of 4% enchancment over baseline.
Informatics Challenges and Options
The instruments described above have been efficiently deployed at go-live and enabled picture integration with the attention PACS, streamlined navigation to imaging orders and interpretation completion, and automatic billing and well being upkeep completion. Nonetheless, within the postdeployment section a number of challenges arose requiring additional iteration.
Managing imaging orders. Not all imaging orders have been accomplished, as a result of the affected person both declined imaging or couldn’t full imaging attributable to their very own time constraints or main care staffing constraints. These orders remained on the screening report for eye care suppliers, inflicting wasted time in looking for these sufferers within the ophthalmology PACS solely to seek out that no photographs have been current. To resolve this, main care employees have been instructed to cancel any imaging orders not accomplished, and the report was modified to replicate cancellation standing to cut back processing time for eye care suppliers.
Undoing automated billing and well being upkeep completion for poor-quality photographs. After implementation, we realized that low-quality photographs resulted in billing and well being upkeep completion attributable to automation within the preliminary construct, regardless that DR screening had not really been accomplished. To deal with this, eye care suppliers manually eliminated the fees and added narrative textual content to the interpretation to tell PCPs that the well being upkeep matter was not fulfilled. We’re pursuing a design modification permitting the attention care supplier to interchange the unique “Teleretina photographs” order with a “Teleretina photographs – Incomplete” order for poor-quality photographs. In testing, this design won’t enter or file a cost, nor will it full the well being upkeep matter. Moreover, the PCP will probably be notified appropriately and the well being upkeep matter will retrigger an alert for DR screening. This modification is present process safety evaluate and isn’t but dwell.
DISCUSSION
This program illustrates how well being IT engagement with multidisciplinary groups was essential for facilitating info circulation between main care clinics and eye care suppliers and subsequently contributing to enhancements in DR screening and documentation essential for monitoring population-level high quality metrics.
Increasing DR screening to main care clinics improved diabetic eye examination metric efficiency. This was according to findings of prior research, such because the discovering by Hatef et al that the probability of finishing an annual diabetic eye examination in a managed care Medicaid inhabitants elevated with entry to a digital camera within the main care clinic.30 Moreover, we screened 316 sufferers over a 9-month interval regardless of the COVID-19 pandemic. This compares favorably to prior research, together with a main care–based mostly program in the identical state that screened 290 sufferers over a 12-month interval previous the pandemic.31 The elevated DR screening charges with main care integration are doubtless attributable to a number of elements, together with avoiding scheduling/referral errors; lowering boundaries related to time, prices, and transportation of attending a separate eye clinic appointment; and constructing upon a trusted relationship with a PCP. The scope of picture acquisition will doubtless additional develop with the provision of handheld cameras and smartphone/cellular cameras and attachments,16,32-35 constructing upon the rising pattern of digital well being and patient-generated information exterior of conventional medical settings.36-38 AI has been one other software in advancing DR screening, with a DR screening system being the primary FDA-approved autonomous AI system in all of medication.39
Well being IT concerns are essential, notably to make sure full and correct switch of imaging and interpretation/outcomes information amongst related events. Integration with present EHR programs and PACS is essential. That is notably difficult for eye care, as a result of ophthalmic imaging distributors typically have proprietary platforms and knowledge requirements adoption stays low.40,41 Ongoing efforts to encourage requirements adoption amongst distributors to facilitate integration amongst eye imaging units, PACS, and EHRs will probably be essential for persevering with to develop DR screening efforts.
One other consideration is designing IT programs to advertise usability and adoption. Creating new DR screening workflows exterior of typical eye clinic encounters required vital buy-in, notably from main clinic employees already going through a number of competing priorities in offering complete care. The contributions of EHRs and well being IT to burnout are well-known in main care,27,42-45 and there may be rising consciousness of the time necessities and burden of well being IT in ophthalmology as effectively.46-49 Thus, we aimed to design the DR screening workflow to include automated elements, facilitate imaging order processing and interpretation completion, and scale back the clicks, navigation, and time wanted. Even then, some unintended penalties arose, together with inappropriate billing and well being upkeep documentation when screening was incomplete attributable to low-quality photographs. This required an iterative strategy with ongoing modifications, illustrating the significance of well being IT engagement after preliminary implementation.
Lastly, we discovered the significance of ongoing monitoring and analysis. Month-to-month conferences generated alternatives to debate site-specific points, determine extra coaching wants, and supply motivation. For instance, a “March Insanity” competitors helped improve screening quantity in spring 2021. Equally, monitoring the proportion of low-quality photographs month-to-month detected an unanticipated improve, which helped determine a digital camera with a technical challenge requiring repairs. Emphasizing the significance of this system and highlighting accomplishments helped preserve morale even when clinics have been beneath vital pressure, corresponding to throughout COVID-19 surges.
Limitations
This program was applied at a single tutorial heart and due to this fact outcomes might not be generalizable. The long-term affect can’t but be measured given the comparatively current implementation. We didn’t measure supplier or affected person satisfaction with this system, which will probably be helpful for future investigations. Lastly, though we designed the informatics instruments underlying this program with ease of use in thoughts, we didn’t formally measure usability. This displays the origin of this system as an operational/medical want quite than as a analysis research per se.
CONCLUSIONS
DR screening is constant to develop past eye clinics and into main care and different settings. The success of those growth efforts will rely partially on well being IT and medical informatics instruments to realize integration with present info programs and facilitate widespread adoption. Well being IT performs an essential function in implementing these packages and increasing DR screening efforts to enhance affected person outcomes.
