Surgical Providers’ Perceptions of the Patient Portal: Before and After the 21st Century Cures Act

IntroductionIn April 2021, the Information Blocking Rule (IBR) of the 21st Century Cures Act went into effect giving patients immediate access to notes, radiology reports, lab results, and surgical pathology. We aimed to examine changes in surgical providers’ perceptions of patient portal usage before and after its implementation. MethodsWe administered a 37-question survey prior to the implementation of the IBR and a 39-question follow-up survey 3 mo later. The survey was sent to all surgeons, advanced practice providers, and clinic nurses in our surgical department. ResultsThe response rate to pre surveys and post surveys was 33.7% and 30.7%, respectively. Providers’ preference for communication via the patient portal (compared to phone or in person) regarding lab, radiology, or pathology results remained similar. While there was an increase in messages received from patients, there was no difference in the self-reported time spent on the electronic health record (EHR). Prior to the implementation of the blocking rule, 75.8% of providers believed that the portal increased workload which decreased to 57.4% on our follow-up survey. About one-third of providers screened positive for burnout before (32%) which decreased slightly (27.4%). ConclusionsAlthough 43.9% of providers reported the Cures Act had changed their practice, there was no difference in self-reported EHR usage, preferred method of interaction with patients, overall workload, or burnout. Initial concerns regarding the IBR's effect on job satisfaction, patient anxiety, and quality of care had lessened. Further exploration into how patients having immediate access to their EHRs has changed surgical practice is needed.

Assessment of the Croatian Open Data Portal Using User-Oriented Metrics

Open data portals are web services that serve as a central access point for all government-published open data and can exist at local, regional, national, and international levels. They are an important element of most open data initiatives that have enabled a large amount of government data to be widely available. However, data quantity and quality are not the only aspects that should be considered when publishing data. To improve the reusability of data and to achieve greater impact and benefits from open data, it is important to consider user-oriented aspects of the portal management, discovery, and use of data (e.g., organizing the portal in a user-centric way, providing accurate metadata, using a standardized and open data format, etc.). In this paper, we adopted the metrics proposed by the European Commission to assess compliance of the Croatian Open Data Portal with 10 user-oriented principles that open data portals should implement in terms of sustainability and added value. While the results show the government’s efforts in publishing data, some aspects such as better collaboration with data providers and other data portals, offering different visualization tools, etc. need to be improved to achieve active use and impact.

Evaluation of Patient-Friendly Diagnosis Clarifications in a Hospital Patient Portal.

Medical data can be difficult to comprehend for patients, but only a limited number of patient-friendly terms and definitions are available to clarify medical concepts. Therefore, we developed an algorithm that generalizes diagnoses to more general concepts that do have patient-friendly terms and definitions in SNOMED CT. We implemented the generalizations, and diagnosis clarifications with synonyms and definitions that were already available, in the problem list of a hospital patient portal. We aimed to assess the extent to which the clarifications cover the diagnoses in the problem list, the extent to which clarifications are used and appreciated by patient portal users, and to explore differences in viewing problems and clarifications between subgroups of users and diagnoses. We measured the coverage of diagnoses by clarifications, usage of the problem list and the clarifications, and user, patient and diagnosis characteristics with aggregated, routinely available electronic health record and log file data. Additionally, patient portal users provided quantitative and qualitative feedback about the clarification quality. Of all patient portal users who viewed diagnoses on their problem list (n = 2,660), 89% had one or more diagnoses with clarifications. In addition, 55% of patient portal users viewed the clarifications. Users who rated the clarifications (n = 108) considered the clarifications to be of good quality on average, with a median rating per patient of 6 (interquartile range: 4-7; from 1 very bad to 7 very good). Users commented that they found clarifications to be clear and recognized the clarifications from their own experience, but sometimes also found the clarifications incomplete or disagreed with the diagnosis itself. This study shows that the clarifications are used and appreciated by patient portal users. Further research and development will be dedicated to the maintenance and further quality improvement of the clarifications.

Generating interactive visual maps of anatomical connectivity from SPARC connectivity knowledge

The December 2022 release of the SPARC Portal ( https://sparc.science ) included the first significant update to the anatomical connectivity flatmaps since the portal first launched. These flatmaps provide an interactive and visual map for the display and exploration of the autonomic nervous system of Human, rat, mouse, pig, and cat ( https://sparc.science/maps ). In addition to improved anatomical ‘cartoons’ for all species and adding a female Human map, these maps, for the first time, automatically render the connectivity knowledge directly retrieved from the SPARC Connectivity Knowledge Base of the Autonomic Nervous System (SCKAN; https://sparc.science/resources/6eg3VpJbwQR4B84CjrvmyD ). SCKAN contains explicit knowledge about CNS-ANS-end organ circuitry derived from SPARC data and scientific literature, in a form that supports computational reasoning. Each flatmap consists of a manually drawn base layer for the species-specific anatomical cartoon and a layer of manually drawn tracts for the large nerves. By annotating these drawings with standard reference SPARC vocabularies consistent with SCKAN usage, software tools are then able to semantically map connectivity circuits retrieved from SCKAN to the visual representation on each species’ flatmap. Beyond the interactive visual rendering of the circuitry on the SPARC Portal, the semantic consistency between flatmaps and SCKAN powers further user interface components on the SPARC Portal to surface additional knowledge for each rendered connection. For example, comprehensive links to the literature and/or data supporting a connectivity statement can be retrieved from SCKAN and provided to Portal users. Now that tools are in place to support this automated workflow to generate the flatmaps from SCKAN knowledge, we are continuing to improve the SPARC Portal to visualise new knowledge as it becomes available.

Wie verändert die regelmäßige Nutzung von Gesundheitsportalen das Verhalten von Patient*innen? – Ergebnisse einer Befragungsstudie

ZusammenfassungHintergrundGesundheitsportale bieten die Möglichkeit, sich ausführlich über Gesundheits- und Krankheitsthemen zu informieren, weiterführenden Rat einzuholen oder Verweisen zu anderen, spezialisierten Informationsportalen zu folgen. Die hohe Zahl an Nutzer*innen, die sich in den Online-Communities der etablierten Gesundheitsportale herausgebildet hat, spricht dafür, dass solche Portale verbreiteten Informations- und Austauschbedürfnissen entgegenkommen.Ziel der ArbeitBislang liegen nahezu keine empirischen Befunde vor, in welcher Weise die intensive Nutzung solcher Dienste das Gesundheitshandeln beeinflusst. Im Zuge dieser Studie wurden regelmäßige Nutzer*innen großer Gesundheitsportale u. a. zu ihren Motiven befragt und welche Veränderungen des Arzt-Patient-Verhältnisses sie seit ihrer regelmäßigen Nutzung an sich beobachten.Material und MethodenMittels einer Online-Befragung wurden im Jahr 2022 insgesamt 936 Nutzer*innen von 13 großen Gesundheitsportalen anonymisiert befragt. Zur Feststellung von signifikanten Unterschieden zwischen zwei Gruppen kam ein t‑Test bei unabhängigen Stichproben zum Einsatz.ErgebnisseGesundheitsportalen wird von den Befragten ein beachtliches Vertrauen entgegengebracht wird. Die Ergebnisse lassen darauf schließen, dass die regelmäßige Nutzung deutliche Folgen für das Arzt-Patient-Verhältnis hat. Die Auswirkungen reichen von einem kompetenteren, reflektierteren und kritischeren Umgang mit Ärzt*innen bis hin zu einem häufigeren Arztwechsel oder sogar einer gänzlichen Abkehr von Ärzt*innen. Zudem bekunden viele Befragte, nach Online-Recherchen oftmals einen Mangel an Orientierung und Entscheidungsunsicherheit zu verspüren.SchlussfolgerungIm Lichte der Resultate ergeben sich neue Anforderungen an die Arzt-Patient-Beziehung. Nicht-kommerzielle Portale zur Gesundheitsinformation sollten weiter gestärkt werden. Auch sollte darüber nachgedacht werden, Maßnahmen zur Verbesserung der Qualität und Transparenz von Gesundheitsportalen zu ergreifen.

Usability and Accessibility of Open Government Data Portals of Countries Worldwide

The open government data (OGD) portal is an initiative by governments worldwide to promote transparency and accountability and enhance citizen participation and public value creation. The ability of these portals to deliver the expected benefits depends on their usability and accessibility, besides their content. This study conducts an integrated assessment and comparison of the OGD portals of 75 countries based on their usability and accessibility. The usability of the portals is measured through several technical indicators, classified into performance metrics, browser timings, and optimisation using automated diagnostic tools. Accessibility is evaluated through portals' conformance to web content accessibility guidelines (WCAG). The ‘technique for order of preference by similarity to ideal solution' (TOPSIS) and entropy weight method are used to rank the portals. The findings of this study could be helpful for policymakers and internal stakeholders of OGD initiatives to identify the focus area and make decisions on resource allocation.

Indian Multinational Restaurant Aggregator And Food Delivery

With the advent of digital technology in food market, online plat-forms have been used to deliver meals from a variety of restaurants through a mobile app. The pace with which this industry is flourishing. It becomes im-perative to have real knowledge about the factors which are contributing to the popularity of these apps and enhancing customer satisfaction. The present re-search reports the results of an empirical study covering 300 respondents across India,based on exploratory,confirmatory factor analysis and Structural Equation Modelling (SEM) to identity satisfaction determinants among food aggregators Viz. single online portal users. Present study envisages three dimensions which are given importance by the customers andsuggests that food aggregator industry should primarily focus on product quality and pricing as core attributes of their service offerings followed by consumer convenience by leveraging the technology to ensure their sustainability in the era of stiff competition in this fastchanging food aggregators market rather than competing on the basis of delivery staff competence as the results give least importance to staff compe-tence (significant at 10% level of significance).

Older Patient Receptivity to the Integration of Patient Portals and Telehealth in Urogynecology: Promoters and Deterrents.

Limited studies focus on the integration of online portals, including telehealth services, in urogynecology while identifying promoters and deterrents of utilization, especially for the older population. This study aimed to identify facilitators, concerns, technical or personal issues encountered, and the desired features of the online patient portals among older urogynecology patients. This is a secondary analysis of a cross-sectional study of older patients (≥65 years). The survey was devised using 2 focus groups with questions addressing older patient practicality and comfort with virtual visits for menopause and urogynecology-specific conditions. A total of 205 patients completed the study. Promoters of use included health care professional encouragement, enrollment on site with concurrent education, and clarification of relevance of the virtual care to one's care. Patients who were uncomfortable with portal use reported anxiety and technical issues as deterrents for using such technology. More than half of the patients were comfortable having online visits for preoperative (51.7%), postoperative (66.3%), and medical management (73.7%). Up to 60.5% of the patients believed that virtual visits were equally stressful as in-person visits, whereas 24.4% believed that the logistics of in-person visits were the cause of stress. To improve access to care, augment the utilization of online patient portals, and combat ageism, enhancing the older urogynecologic patient's portal experience is vital. Investment in this population's needs includes education of patients, active enrollment, and engagement by health care systems, and addressing technical concerns.

Quad Tendon Autograft for Posterior Cruciate Ligament Reconstruction Using Transseptal and Posteromedial Portals

We describe a surgical technique for reconstruction of the posterior cruciate ligament with quad tendon autograft using transseptal portal. We place the guide for the tibial socket through the posteromedial portal instead of transnotch, which is the most common practice. The use of the transseptal portal allows good visualization during the drilling of the tibial socket to protect the neurovascular bundle while avoiding the use of fluoroscopy. The advantage of using the posteromedial approach is the easy placement of the drill guide and to option to pull the graft once through the posteromedial portal and a second time through the notch, which helps passing the “killer turn.” The quad tendon is harvested with a bone block that is placed in the tibial socket and fixed with screws in the tibial and femoral side.

The Association Between Sociodemographic Factors, Social Determinants of Health, and Spine Surgical Patient Portal Utilization.

Retrospective cohort study. To examine patient portal use among the surgical spine patient population across different sociodemographic groups and assess the impact of patient portal use on clinical outcomes. Patient portals (PP) have been shown to improve outcomes and quality of care. Engaging them requires internet access, technological literacy, and dexterity, which may serve as access barriers. After exclusion criteria were applied, the study included data for 9211 encounters from 7955 patients. PP utilization was defined as having activated and used the Duke University Medical Center patient portal system, MyChart, at least once. Sociodemographic characteristics included urbanicity, age, race, ethnicity, language, employment, and primary insurer. Clinical outcomes included the length of hospital stay during the procedure, 30-day return to the emergency department, 30-day readmission, and being discharged somewhere other than home. Being older than 65, non-White, unemployed, non-English-speaking, male, not-partnered, uninsured or publicly insured (Medicaid, Medicare and under 65 years of age, or other government insurance), and living in a rural environment were all risk factors for decreased PP utilization among surgical spine patients. A one-risk factor decrease in the number of social risk factors was associated with a 78% increase in the odds of PP utilization [odds ratio (OR): 1.78; 95% Confidence interval (CI): 1.69-1.87; P <0.001]. Patients not utilizing the portal at the time of their procedure had higher odds of 30-day readmission (OR: 1.59; 95% CI: 1.26-2.00), discharge somewhere other than home (OR: 2.41, 95% CI: 1.95-2.99), and an increased length of hospital stay (geometric mean ratio: 1.21; 95% CI: 1.12-1.30) compared with those who utilized it. In patients undergoing spine procedures, PPs are not equally utilized among different sociodemographic groups. PP utilization is also associated with better outcomes. Interventions aimed at increasing PP uptake may improve care for certain patients.

Empirical analysis of open government data usage in Tanzania

PurposeDespite the potential benefits of open government data (OGD) and its recent adoption by many governments, little is known about monitoring its use by the public. This paper aims to address the knowledge gap by empirically examining OGD usage in Tanzania.Design/methodology/approachA field survey design was used to gather quantitative data from 288 people in seven regions of Tanzania to facilitate an analysis of the determinants of users’ behavioural intention and use behaviour of OGD. Guided by the Unified Theory of Acceptance and Use of Technology model, the study analysed the tendencies of these determinants on the use of the OGD portal.FindingsThe results show that performance expectancy, effort expectancy, social influence and facilitating conditions affect users’ acceptance and use of the OGD portal. The results suggest that OGD initiatives should focus more on their potential applications than publication. It is important to monitor and evaluate OGD use and the conditions that allow it to continue. By linking OGD with other government initiatives, governments can build strategies, capacity and social awareness. During the development of OGD platforms for extensive reuse, new data technologies like the semantic web should be considered.Originality/valueHitherto, research has underlined the significance of OGD initiatives at large and that studies in developing countries are scarce, especially that probe the uptake of the current efforts. The present study seeks to plug this research gap by examining the use of OGD in Tanzania’s context.

Profiles of Web-based Portal Users with Inflammatory Bowel Disease.

Web-based portals can enhance communication between patients and providers to support IBD self-management and improve care. We aimed to identify portal use patterns of patients with inflammatory bowel disease (IBD) to inform future web portal-based interventions and portal design. Patients with IBD receiving care at the University of Michigan between 2012 and 2021 were identified. Meta-data from electronic logs of each patient's most recent year of portal use were abstracted. Portal engagement was characterized in terms of intensity (ie, frequency of use); comprehensiveness (ie, number of portal functions used); and duration (ie, quarters per year of portal use). We used k-means clustering, a machine-learning technique, to identify groupings of portal users defined in terms of engagement features. We found 5605 patients with IBD who had accessed their portal account at least once. The average age was 41.2 years (SD 16.7), 3035 (54.2%) were female, and 2214 (39.5%) received immune-targeted therapies. We identified 3 patterns of portal engagement: (1) low intensity users (29.5%); (2) moderate intensity, comprehensive, and sustained users (63.3%); and (3) high intensity, comprehensive, sustained users (7.2%). Patients with more intense, comprehensive, and sustained use of the portal were older, female, with more comorbidities, and were more likely to receive immune-targeted therapies. Understanding distinct patterns of portal use can inform portal-based interventions and portal design. Patient portals may be particularly helpful in delivering assistance to those with comorbidities and those receiving immune-targeted therapies-many of whom demonstrate more intense, comprehensive, and sustained portal use.

21st Century Cures Act ONC Rule: Implications for Adolescent Care and Confidentiality Protections

Ensuring the confidentiality and protection of health information is the standard of care for adolescents. In 2023 and beyond, the protection of personal health information is more critical than ever. The 21st Century Cures Act Office of the National Coordinator for Health Information Technology Rule, with its requirements for the broad sharing of electronic health information and ban on "information blocking," poses serious concerns for confidentiality in adolescent health care delivery. The coronavirus disease 2019 pandemic has rapidly increased the use of telehealth and, thereby, patient portal use for adolescent health records, increasing risks for disclosure. Understanding the legal and clinical underpinnings for confidential adolescent health services and the clinical challenges and health information technology limitations presented by the Office of the National Coordinator for Health Information Technology Rule is key to providing quality adolescent health services while implementing the Rule. A framework is presented to facilitate decision-making in individual cases by clinicians.

Perceptions on the Utility of Community Question and Answer Websites Like Stack Overflow to Software Developers

Software developers make use of on crowdsourcing during development. Beyond learning from others, developers use online portals such as Stack Overflow as a vehicle for collaboration. However, little is known about developers' experiences on such platforms, particularly around problems that are encountered online. Such insights could benefit software developers in terms of recommendations for pitfalls to avoid, ways to exploit crowdsourced knowledge, and the provision of insights to improve online code sharing communities. We interviewed 50 practitioners to fill this gap, where outcomes show that software developers' use of online portals is targeted, and such portals are a lifeline to modern software development. Practitioners are facilitated with code solutions and debugging, often in a very timely fashion. While these experiences are largely positive, practitioners also encounter negative experiences online, some of which could be significantly deleterious to the community. We discuss the implications of these findings, such as creating awareness of the quality and reliability of code snippets, improving code searches, code validation and outdated code detection and attribution of code snippets.

STREAMLINING LAUNDRY SERVICES USING INNOVATIVE WEBSITE

Laundry as a notion has changed over time. Laundry services and subsequently washing machines have supplanted the practice of doing our own laundry. Thus, much clever labor has taken the place of much hard work. Laundry stores, which greatly decreased the amount of laundry people had to do at home back then, were where the idea and development of laundry first began. which actually led to greater labour and energy savings. Based on current Internet technology advancements, laundry will evolve, and its clever work will become better and more effective as a website known as The Laundry Management. This will happen due to the fast use of online portals and other sites. It will also make a few suggestions to help this idea succeed. The data is gathered solely from secondary sources, i.e., through a review of literature, and thus it is a philosophical study.

Risks Associated With Posterior Ankle Hindfoot Arthroscopy Complications.

The use of posterior ankle and hindfoot arthroscopy (PAHA) has been expanding over time. Many new indications have been reported in the literature. The primary objective of this study was to report the rate of PAHA complication in a large cohort of patients and describe their potential associations with demographical and surgical variables. In this IRB-approved retrospective comparative study, patients who underwent posterior ankle and/or hindfoot arthroscopy in a single institution from December 2009 to July 2016 were studied. Three fellowship-trained orthopaedic foot and ankle surgeon performed all surgeries. Demographic data, diagnosis, tourniquet use, associated procedures, and complications were recorded. To investigate a priori factors predictive of neurologic complication after PAHA, univariate and multivariable logistic regression was utilized. Where appropriate, sparse events sensitivity analysis was tested by fitting models with Firth log-likelihood approach. A total of 232 subjects with 251 surgeries were selected. Indications were posterior ankle impingement (37%), flexor hallux longus disorders (14%), subtalar arthritis (8%), and osteochondral lesions (6%). Complications were observed in 6.8% (17/251) of procedures. Neural sensory lesions were noted in 10 patients (3.98%), and wound complications in 4 ankles (1.59%). Seven neurologic lesions resolved spontaneously and 3 required further intervention. In a multivariable regression model controlled for confounders, the use of accessory posterolateral portal was the significant driver for neurologic complications (odds ratio [OR] 32.19, 95% CI 3.53-293.50). The complication rate in this cohort that was treated with posterior ankle and/or hindfoot arthroscopy was 6.8%. Most complications were due to neural sensorial injuries (sural 5, medial plantar nerve 4, medial calcaneal nerve 1 ) and 3 required additional operative treatment. The use of an accessory posterolateral portal was significantly associated with neurologic complications. The provided information may assist surgeons in establishing diagnoses, making therapeutic decisions, and instituting surgical strategies for patients that might benefit from a posterior arthroscopic approach. Level III, retrospective comparative study.

Determinants of Telehealth Technologies in a Rural Population.

Background: Telehealth's applicability may be limited for vulnerable populations including rural communities. While broadband access is a known barrier to telehealth use, other factors may influence a person's ability or preference to use telehealth. Objective/Purpose: To compare characteristics of telehealth users versus nontelehealth users in a rural health care network. Methods: We surveyed a stratified random sample of 500 adult patients in August 2021 about telehealth use. We used descriptive statistics to compare characteristics of telehealth users with nontelehealth users. Telehealth was defined in three different ways as follows: (1) phone or video visit, (2) video visit, and (3) patient portal use. Results: Mean age of the 206 respondents was 60 years, 60.7% were female, 60.4% had some college education; 84.9% had home internet, and 73.3% used the internet independently. Video telehealth use was independently associated with younger age (<65), having some college education, being married/partnered, and being enrolled in Medicaid. When telehealth included a phone option, disability was positively associated with telehealth use, and living in a rural town versus metropolitan/micropolitan area was negatively associated with telehealth use. Being younger, married/partnered, and having some college education were significantly associated with patient portal use. Conclusion: Videoconferencing and patient portal use pose barriers to those who are older and have less education. However, these barriers disappear when telehealth is available through telephone.

Patient-reported outcomes for oral oncolytic therapy: A pilot study utilizing an electronic patient portal in a community cancer center.

A pilot project was initiated to determine the feasibility of using an electronic patient portal, MyChart, for documentation of patient-reported outcomes for those receiving treatment with an oral oncolytic. Documentation of patient-reported outcomes within the electronic medical record before and after implementing questionnaires through the use of MyChart was compared. Additional outcomes that were assessed included patient confidence and satisfaction, adherence rate, side effects, and documentation of provider interventions. Our findings indicate that the use of an electronic patient portal significantly increased the number of encounters documented within the electronic medical record from 1.8% (N = 19 patients; 1 out of 55 potential encounters; retrospective analysis) to 27.5% (N = 15 patients; 14 out of 51 potential encounters; prospective analysis) for those who utilized an electronic patient portal (p < 0.001). Patient confidence and satisfaction were high, the adherence rate was 100% at 4 months, and side effects were generally mild. Provider follow-up was documented in the electronic medical record in 6 out of 8 patients when a flagged response was identified. This pilot study indicates that the use of an electronic patient portal, MyChart, was feasible and improved documentation of patient-reported outcomes within the electronic medical record. Several information technologies and patient barriers were encountered throughout. Careful selection of patients who will embrace this technology is important.

Using Machine Learning Algorithms to Predict Patient Portal Use Among Emergency Department Patients With Diabetes Mellitus.

Different machine learning (ML) technologies have been applied in healthcare systems with diverse applications. We aimed to determine the model feasibility and accuracy of predicting patient portal use among diabetic patients by using six different ML algorithms. In addition, we also compared model performance accuracy with the use of only essential variables. This was a single-center retrospective observational study. From March 1, 2019 to February 28, 2020, we included all diabetic patients from the study emergency department (ED). The primary outcome was the status of patient portal use. A total of 18 variables consisting of patient sociodemographic characteristics, ED and clinic information, and patient medical conditions were included to predict patient portal use. Six ML algorithms (logistic regression, random forest (RF), deep forest, decision tree, multilayer perception, and support vector machine) were used for such predictions. During the initial step, ML predictions were performed with all variables. Then, the essential variables were chosen via feature selection. Patient portal use predictions were repeated with only essential variables. The performance accuracies (overall accuracy, sensitivity, specificity, and area under receiver operating characteristic curve (AUC)) of patient portal predictions were compared. A total of 77,977 unique patients were placed in our final analysis. Among them, 23.4% (18,223) patients were diabetic mellitus (DM). Patient portal use was found in 26.9% of DM patients. Overall, the accuracy of predicting patient portal use was above 80% among five out of six ML algorithms. The RF outperformed the others when all variables were used for patient portal predictions (accuracy 0.9876, sensitivity 0.9454, specificity 0.9969, and AUC 0.9712). When only eight essential variables were chosen, RF still outperformed the others (accuracy 0.9876, sensitivity 0.9374, specificity 0.9932, and AUC 0.9769). It is possible to predict patient portal use outcomes when different ML algorithms are used with fair performance accuracy. However, with similar prediction accuracies, the use of feature selection techniques can improve the interpretability of the model by addressing the most relevant features.

Desires for Individual- and Interpersonal-Level Patient Portal Use for HIV Prevention Among Urban Sexual Minority Men: Cross-sectional Study.

Gay, bisexual, and other sexual minority men have expressed the acceptability of patient portals as tools for supporting HIV prevention behaviors, including facilitating disclosure of HIV and other sexually transmitted infection (STI/HIV) laboratory test results to sex partners. However, these studies, in which Black or African American sexual minority men were undersampled, failed to determine the relationship of reported history of discussing HIV results with sex partners and anticipated willingness to disclose web-based STI/HIV test results using a patient portal. Among a sample of predominantly Black sexual minority men, this study aimed to (1) determine preferences for patient portal use for HIV prevention and (2) test the associations between reported history of discussing HIV results and anticipated willingness to disclose web-based STI/HIV test results with most recent main and nonmain partners using patient portals. Data come from audio-computer self-assisted interview survey data collected during the 3-month visit of a longitudinal cohort study. Univariate analysis assessed patient portal preferences by measuring the valuation rankings of several portal features. Multiple Poisson regression models with robust error variance determined the associations between history of discussing HIV results and willingness to disclose those results using web-based portals by partner type, and to examine criterion validity of the enhancing dyadic communication (EDC) scale to anticipated willingness. Of the 245 participants, 71% (n=174) were Black and 22% (n=53) were White. Most participants indicated a willingness to share web-based STI/HIV test results with their most recent main partner. Slightly fewer, nonetheless a majority, indicated a willingness to share web-based test results with their most recent nonmain partner. All but 2 patient portal features were valued as high or moderately high priority by >80% of participants. Specifically, tools to help manage HIV (n=183, 75%) and information about pre- and postexposure prophylaxis (both 71%, n=173 and n=175, respectively) were the top-valuated features to include in patient portals for HIV prevention. Discussing HIV test results was significantly associated with increased prevalence of willingness to disclose web-based test results with main (adjusted prevalence ratio [aPR] 1.46, 95% CI 1.21-1.75) and nonmain partners (aPR 1.54, 95% CI 1.23-1.93). Our findings indicate what features Black sexual minority men envision may be included in the patient portal's design to optimize HIV prevention, further supporting the criterion validity of the EDC scale. Efforts should be made to support Black sexual minority men's willingness to disclose STI/HIV testing history and status with partners overall as it is associated significantly with a willingness to disclose testing results digitally via patient portals. Future studies should consider discussion behaviors regarding past HIV test results with partners when tailoring interventions that leverage patient portals in disclosure events.
