Patient Dietary Supplements Use: Do Results from Natural Language Processing of Clinical Notes Agree with Survey Data?

There is widespread use of dietary supplements, some prescribed but many taken without a physician's guidance. There are many potential interactions between supplements and both over-the-counter and prescription medications in ways that are unknown to patients. Structured medical records do not adequately document supplement use; however, unstructured clinical notes often contain extra information on supplements. We studied a group of 377 patients from three healthcare facilities and developed a natural language processing (NLP) tool to detect supplement use. Using surveys of these patients, we investigated the correlation between self-reported supplement use and NLP extractions from the clinical notes. Our model achieved an F1 score of 0.914 for detecting all supplements. Individual supplement detection had a variable correlation with survey responses, ranging from an F1 of 0.83 for calcium to an F1 of 0.39 for folic acid. Our study demonstrated good NLP performance while also finding that self-reported supplement use is not always consistent with the documented use in clinical records.

"Giving the patients less work": A thematic analysis of telehealth use and recommendations to improve usability for autistic adults.

LAY ABSTRACT: Real-time telehealth visits, called "virtual visits," are live video chats between patients and healthcare professionals. There are lots of steps involved in setting up a virtual visit, which may be difficult for some autistic adults. We interviewed 7 autistic adults, 12 family members of autistic adults, and 6 clinic staff from one clinic in the United States. Our goal was to understand their experiences with virtual visits and see how we can make virtual visits easier to use. We re-read text from the interviews to organize experiences and advice that was shared into topics. We found that autistic adults (or their family members) had to connect with clinic staff many times by phone or online over several days to set up a virtual visit. Participants said that having more experience with technology and using the online patient portal made virtual visits easier to use. But, having issues with technology before the visit could make autistic adults and family members anxious. Clinic staff said it was hard for them to meet the needs of people who were using virtual visits and those who were being seen in person at the clinic. Participants recommended reducing the number of calls between staff and autistic adults or family members using the online patient portal instead. Participants also recommended reminder messages, instruction videos, and approximate wait-times to help autistic adults and family members know what to expect for the virtual visit. Our results are based on peoples' experiences at one clinic, but could help other clinics make virtual visits easier to use for autistic adults and their family members.

Extracurricular Humanism in Medicine Initiative and Medical Student Wellness: Retrospective Study.

BACKGROUND: Humanism in Medicine Initiative (HIMI), an extracurricular program at Ohio State University College of Medicine (OSUCOM) with 27 subgroups, fosters the humanities. Stress and burnout among first- and second-year medical students are prevalent across the United States. Solutions for stress among first- and second-year medical students have been proposed, but no gold standard exists. The relationship of humanism with stress and burnout has yet to be described in the literature. OBJECTIVE: This study investigates the relationship between participation in the HIMI and stress, burnout, and academic success among first- and second-year medical students. METHODS: First- and second-year medical students enrolled at OSUCOM between August 2018 and August 2019 were recruited. Attendance in the HIMI and membership records were used to measure their participation. Curricular examination scores and those on Step 1 of United States Medical Licensing Examination (USMLE) were used to measure academic success. Stress and burnout were measured using the Maslach Burnout Inventory and the Perceived Stress Scale. RESULTS: In total, 412 students were enrolled with 362 (87%) students participating in HIMI. Those with high participation were more often Black, Asian, female, or with a humanities undergraduate major compared to the overall study population. There were significant relationships between Gold Humanism Honors Society (GHHS) induction and participation of first- and second-year medical students in service- (χ21=5.8, P<.05) or leadership-focused (χ21=19.3, P<.001) HIMI groups. Medium levels of participation in the HIMI were associated with significantly higher stress. Performance on the Step 1 USMLE was not significantly associated with participation levels in the HIMI (low=233.7 vs high=238.0; P=.10). CONCLUSIONS: The HIMI is an extracurricular program vastly utilized by first- and second-year medical students at OSUCOM and did not impact Step 1 USMLE scores. Medium participation in the HIMI was associated with higher stress, and service- and leadership-focused HIMI participation was associated with a higher level of induction to the GHHS. This study identifies areas for future studies to understand the relationship of the HIMI with stress and academic success.

Expenditures and Healthcare Utilization of Patients Receiving Care at a Specialized Primary Care Clinic Designed with and for Autistic Adults.

BACKGROUND: We previously found that autistic adults who received care through a primary care embedded specialized clinic, called the Center for Autism Services and Transition (CAST), had higher satisfaction, continuity of care, and preventive care use than national samples of autistic adults. OBJECTIVE: Examine the impact of CAST on healthcare utilization and expenditures. DESIGN: Retrospective study of medical billing data. SAMPLE: CAST patients (N = 490) were propensity score matched to Medicare-enrolled autistic adults (N = 980) and privately insured autistic adults (N = 980) using demographic characteristics. The median age of subjects was 21 years, 79% were male, and the median duration of observation was 2.2 years. MAIN MEASURES: We quantified expenditures and utilization for primary care; emergency department (ED) visits; inpatient hospitalizations; mental health admissions; and outpatient visits. KEY RESULTS: CAST patients had the highest primary care utilization and expenditures. However, CAST patients had significantly lower expenditures than Medicare-enrolled autistic adults for mental health admissions ($1074 vs $1903), outpatient visits ($1671 vs $2979), and total expenditures ($5893 vs $6987), as well as 57% fewer inpatient hospitalizations. Compared to privately insured autistic adults, CAST patients had significantly lower expenditures for mental health admissions ($1074 vs $1362), inpatient hospitalizations ($3851 vs $4513), and outpatient visits ($1671 vs $6070), as well as 16% fewer inpatient hospitalizations, 24% fewer ED visits, and 50% fewer outpatient visits. On average, CAST patients had more ED visits, mental health admissions, and outpatient visits than Medicare-enrolled autistic adults and more mental health admissions than privately insured autistic adults. CONCLUSIONS: Although CAST patients had greater primary care utilization and expenditures, our findings suggest embedding specialized clinics within broader primary care settings could be an alternative to current standards of care and may reduce expenditures and healthcare utilization in other areas, particularly relative to standard care for privately insured autistic adults.

"It was surprisingly equivalent to the appointment I had in person": Advantages and disadvantages of synchronous telehealth for delivering primary care for autistic adults.

LAY ABSTRACT: Autistic adults face many barriers to receiving quality primary health care like clinics that are far away and sensory sensitivities. Real-time telehealth visits, called "virtual visits," are live video chats between the patient and provider. Virtual visits may minimize barriers to care for autistic adults. We wanted to describe advantages and disadvantages of using virtual visits for delivering primary health care for autistic adults. We interviewed 7 autistic adults and 12 caregivers of autistic adults who receive primary care through one clinic. Autistic adults and caregivers said advantages to virtual visits were that (1) patients were more comfortable at home, (2) patients could get health care while avoiding physical contact with other people during the pandemic, and (3) virtual visits were similar to or better than in-person visits. The disadvantages included that (1) there could be technology problems like grainy video, (2) the doctor could not physically examine the patient (e.g. look in ears), and (3) patients sometimes participated less in the virtual visit than they would in person. Virtual visits may be beneficial for autistic adults by eliminating travel to the clinic and avoiding stressful sensory stimuli. We recognize that virtual visits may not work for all patients or in all situations. However, our study shows that primary care virtual visits may be beneficial for autistic adults during and beyond the pandemic.

Characteristics associated with healthcare independence among autistic adults.

Background: Healthcare independence refers to someone's ability to assume responsibility for their own health and complete tasks like taking medication as prescribed or scheduling healthcare appointments. Prior studies have shown that autistic people tend to need more support with healthcare tasks than people with other chronic conditions. We sought to identify modifiable and non-modifiable factors linked with healthcare independence among autistic adults. Method: We conducted a cross-sectional survey to examine how executive functioning skills, restrictive and repetitive behaviors, gender, education, and age were linked with healthcare independence among this population. Participants included: (a) autistic adults (n=19) who are their own legal guardian, who participated via self-report; and (b) family members of autistic adults with a legal guardian (n=11), who provided proxy-reports. Results: Findings differed between self- and proxy-reports. Among autistic adults who self-reported, difficulties in executive functioning were strongly linked with less healthcare independence. Among proxy-reports, greater restrictive and repetitive behaviors were strongly linked with less healthcare independence. According to the proxy-reports, having not completed high school, being older during the healthcare transition, and being male were all independently linked with less healthcare independence. Conclusions: Interventions aimed at supporting executive functioning, providing opportunities to increase independence with healthcare tasks, and reducing the extent to which restrictive and repetitive behaviors interfere with daily activities may be viable options for supporting healthcare independence among autistic adults. Our findings are an important first step for future initiatives to better identify individuals who need additional care coordination, supports, or services to maximize healthcare independence.

Assessment of Fall-Related Emergency Medical Service Calls and Transports after a Community-Level Fall-Prevention Initiative.

Background: Getting effective fall prevention into the homes of medically and physically vulnerable individuals is a critical public health challenge. Community paramedicine is emerging globally as a new model of care that allows emergency medical service units to evaluate and treat patients in non-emergency contexts for prevention efforts and chronic care management. The promise of community paramedicine as a delivery system for fall prevention that scales to community-level improvements in outcomes is compelling but untested.Objective: To study the impact of a community paramedic program's optimization of a fall prevention system entailing a clinical pathway and learning health system (called Community-FIT) on community-level fall-related emergency medical service utilization rates.Methods: We used an implementation science framework and quality improvement methods to design and optimize a fall prevention model of care that can be embedded within community paramedic operations. The model was implemented and optimized in an emergency medical service agency servicing a Midwestern city in the United States (∼35,000 residents). Primary outcome measures included relative risk reduction in the number of community-level fall-related 9-1-1 calls and fall-related hospital transports. Interrupted time series analysis was used to evaluate relative risk reduction from a 12-month baseline period (September 2016 - August 2017) to a 12-month post-implementation period (September 2018-August 2019).Results: Community paramedic home visits increased from 25 in 2017, to 236 in 2018, to 517 in 2019, indicating a large increase in the number of households that benefited from the efforts. A relative risk reduction of 0.66 (95% [CI] 0.53, 0.76) in the number of fall calls and 0.63 (95% [CI] 0.46, 0.75) in the number of fall-related calls resulting in transports to the hospital were observed.Conclusions: Community-FIT may offer a powerful mechanism for community paramedics to reduce fall-related 9-1-1 calls and transports to hospitals that can be implemented in emergency medical agencies across the country.

Practical Guide to Implementation Science for Surgical Oncologists: Case Study of Breast Cancer Short Stay Program.

BACKGROUND: Long lags exist in adoption and uptake of evidence-based interventions into real-world clinical practice based on oncology clinical trial results. Implementation science (IS) is a distinct field of health services research that aims to understand the barriers related to adoption of evidence-based guidelines and research in clinical practice. METHODS: Use of IS study design, methods, and outcomes can be elusive to surgical oncologists despite the tremendous need for the application of IS to bridge the evidence-to-practice gap. This report describes key components of high-quality IS. RESULTS: Herein, we illustrate how IS can be used in surgical oncology practice. Examples from implementation of the breast cancer Short Stay Program (SSP) in Netherlands is used to illustrate IS methods. Specific funding and training opportunities in implementation science are described in detail. CONCLUSION: Use of IS in surgical oncology can help improve the uptake of evidence based medicine.

Interoperable genetic lab test reports: mapping key data elements to HL7 FHIR specifications and professional reporting guidelines.

OBJECTIVE: In many cases, genetic testing labs provide their test reports as portable document format files or scanned images, which limits the availability of the contained information to advanced informatics solutions, such as automated clinical decision support systems. One of the promising standards that aims to address this limitation is Health Level Seven International (HL7) Fast Healthcare Interoperability Resources Clinical Genomics Implementation Guide-Release 1 (FHIR CG IG STU1). This study aims to identify various data content of some genetic lab test reports and map them to FHIR CG IG specification to assess its coverage and to provide some suggestions for standard development and implementation. MATERIALS AND METHODS: We analyzed sample reports of 4 genetic tests and relevant professional reporting guidelines to identify their key data elements (KDEs) that were then mapped to FHIR CG IG. RESULTS: We identified 36 common KDEs among the analyzed genetic test reports, in addition to other unique KDEs for each genetic test. Relevant suggestions were made to guide the standard implementation and development. DISCUSSION AND CONCLUSION: The FHIR CG IG covers the majority of the identified KDEs. However, we suggested some FHIR extensions that might better represent some KDEs. These extensions may be relevant to FHIR implementations or future FHIR updates.The FHIR CG IG is an excellent step toward the interoperability of genetic lab test reports. However, it is a work-in-progress that needs informative and continuous input from the clinical genetics' community, specifically professional organizations, systems implementers, and genetic knowledgebase providers.

A qualitative investigation of biomedical informatics interoperability standards for genetic test reporting: benefits, challenges, and motivations from the testing laboratory's perspective.

PURPOSE: Genetic laboratory test reports can often be of limited computational utility to the receiving clinical information systems, such as clinical decision support systems. Many health-care interoperability (HC) standards aim to tackle this problem, but the perceived benefits, challenges, and motivations for implementing HC interoperability standards from the labs' perspective has not been systematically assessed. METHODS: We surveyed genetic testing labs across the United States and conducted a semistructured interview with responding lab representatives. We conducted a thematic analysis of the interview transcripts to identify relevant themes. A panel of experts discussed and validated the identified themes. RESULTS: Nine labs participated in the interview, and 24 relevant themes were identified within five domains. These themes included the challenge of complex and changing genetic knowledge, the motivation of competitive advantage, provided financial incentives, and the benefit of supporting the learning health system. CONCLUSION: Our study identified the labs' perspective on various aspects of implementing HC interoperability standards in producing and communicating genetic test reports. Interviewees frequently reported that increased adoption of HC standards may be motivated by competition and programs incentivizing and regulating the incorporation of interoperability standards for genetic test data, which could benefit quality control, research, and other areas.

A qualitative study of prevalent laboratory information systems and data communication patterns for genetic test reporting.

PURPOSE: The availability of genetic test data within the electronic health record (EHR) is a pillar of the US vision for an interoperable health IT infrastructure and a learning health system. Although EHRs have been highly investigated, evaluation of the information systems used by the genetic labs has received less attention-but is necessary for achieving optimal interoperability. This study aimed to characterize how US genetic testing labs handle their information processing tasks. METHODS: We followed a qualitative research method that included interviewing lab representatives and a panel discussion to characterize the information flow models. RESULTS: Ten labs participated in the study. We identified three generic lab system models and their relevant characteristics: a backbone system with additional specialized systems for interpreting genetic results, a brokering system that handles housekeeping and communication, and a single primary system for results interpretation and report generation. CONCLUSION: Labs have heterogeneous workflows and generally have a low adoption of standards when sending genetic test reports back to EHRs. Core interpretations are often delivered as free text, limiting their computational availability for clinical decision support tools. Increased provision of genetic test data in discrete and standard-based formats by labs will benefit individual and public health.

Effects of a Specialized Primary Care Facility on Preventive Service Use Among Autistic Adults: a Retrospective Claims Study.

BACKGROUND: While in some studies, the patient-centered medical home has been linked with increased receipt of preventive services among other populations, there is a paucity of literature testing the effectiveness of medical homes in serving the healthcare needs of autistic adults. OBJECTIVE: To compare the receipt of preventive services by patients at a patient-centered medical home specifically designed for autistic adults (called the Center for Autism Services and Transition "CAST") to US national samples of autistic adults with private insurance or Medicare. DESIGN: Retrospective study of medical billing data. SAMPLE: The study sample included CAST patients (N = 490) who were propensity score matched to Medicare-enrolled autistic adults (N = 980) and privately insured autistic adults (N = 980) using demographic characteristics. The median age of subjects was 21 years old, 79% were male, and the median duration of observation was 2.2 years. MAIN MEASURES: The primary outcome measure was the receipt of any preventive service, as defined by the Medicare Learning Network and AAPC (formerly the American Academy of Professional Coders). Secondary outcome measures included receipt of specific preventive service types (i.e., general health and wellness services, screenings, counseling and therapies, vaccinations, and sexual/reproductive health services). KEY RESULTS: CAST patients had significantly greater odds of receiving any preventive service than Medicare-enrolled (OR = 10.3; 95% CI = 7.6-13.9) and privately insured (OR = 3.1; 95% CI = 2.3-4.2) autistic adults. CAST patients were also significantly more likely to receive screenings and vaccinations than either Medicare beneficiaries (screenings OR = 20.3; 95% CI = 14.7-28.0; vaccinations OR = 5.5; 95% CI = 4.3-7.0) or privately insured beneficiaries (screenings OR = 2.0; 95% CI = 1.6-2.5; vaccinations OR = 3.3; 95% CI = 2.6-4.1). CONCLUSIONS: Autistic adults receiving care through CAST were significantly more likely to recieve preventive care services than national samples of autistic adults. Future comparative effectiveness trials are needed to rigorously assess the impact of primary care-based initiatives to improve care for autistic adults.

Specialized primary care medical home: A positive impact on continuity of care among autistic adults.

LAY ABSTRACT: There is a nationally recognized need for innovative healthcare delivery models to improve care continuity for autistic adults as they age out of pediatric and into adult healthcare systems. One possible model of care delivery is called the "medical home". The medical home is not a residential home, but a system where a patient's healthcare is coordinated through a primary care physician to ensure necessary care is received when and where the patient needs it. We compared the continuity of care among autistic adult patients at a specialized primary care medical home designed to remove barriers to care for autistic adults, called the CAST, to matched national samples of autistic adults with private insurance or Medicare. Continuity of primary care among CAST patients was significantly better than that of matched national samples of autistic adult Medicare beneficiaries and similar to that of privately insured autistic adults. Our findings suggest that medical homes, like CAST, are a promising solution to improve healthcare delivery for the growing population of autistic adults.

"They looked at me as a person, not just a diagnosis": A qualitative study of patient and parent satisfaction with a specialized primary care clinic for autistic adults.

BACKGROUND: Autistic adults have complex physical and mental healthcare needs that necessitate specialized approaches to healthcare. One promising approach is to embed providers with specialized training or specialty clinics for autistic adults within general primary care facilities. We previously found that autistic adults who received their healthcare through one specialty clinic designed with and for autistic adults had better continuity of care and more preventive service utilization than national samples of autistic adults. OBJECTIVE: To characterize factors that increased or decreased satisfaction with healthcare received through a specialty clinic for autistic adults. METHODS: We conducted 30-60-minute semi-structured interviews with autistic adults (N=9) and parents of autistic adults (N=12). We conducted an inductive thematic analysis, using a phenomenological approach. RESULTS: Factors that increased participants' satisfaction included: (1) receiving personalized care from the provider; (2) spending quality time with the provider; and (3) having strong, positive patient-provider relationships. Factors that decreased participants' satisfaction included: (1) lack of access to services due to scarcity of trained providers; (2) difficulty at times communicating with the provider; and (3) system-level barriers such as policies, practices, or procedures. CONCLUSION: Our findings highlight the importance of providers using personalized approaches to care that meet patients' sensory and communication needs and spending quality time with patients to establish strong, positive patient-provider relationships. Our findings also underscore the critical scarcity of healthcare providers who are trained to deliver care for the growing population of autistic adults.

Patient and caregiver experiences at a specialized primary care center for autistic adults.

Background: Little is known about the extent to which patient-centered medical homes meet the needs of autistic adults. Materials & methods: We conducted a cross-sectional survey of autistic adult patients (n = 47) and caregivers of autistic adult patients (n = 66) receiving care through one patient-centered medical home specifically designed to meet the needs of this population. We performed post hoc comparisons of our results to previously published data from a national sample of autistic adults. Results: Participants reported high levels of satisfaction with care, frequent preventive healthcare use and few unmet healthcare needs. Autistic adults in our sample reported significantly higher satisfaction and fewer unmet healthcare needs. Conclusion: A patient-centered medical home tailored to the needs of autistic adults is a promising approach to healthcare delivery for meeting this population's needs.

Feasibility of Capturing Cancer Treatment Data in the Utah All-Payer Claims Database.

PURPOSE: Incompleteness of treatment data is a recognized limitation of cancer registry data. An all-payer claims database (APCD) is a tool that states use to capture health care information across systems and payer. We linked the Utah Cancer Registry (UCR) records to Utah's statewide APCD and evaluated how this linkage led to improvements in the capture of cancer treatment information. METHODS: We linked cancers diagnosed and reported to the UCR with Utah APCD claims for the calendar years 2013 and 2014 using LinkPlus Software. For patients with breast or colorectal cancers, manual abstraction was completed to provide a gold-standard comparison for the treatment data obtained from the claims. RESULTS: Among 10,759 reportable cancer occurrences linked to the APCD, the claims identified additional patients with cancer who received therapies that had been unknown to the registry, increasing the proportion treated with chemotherapy from 23.7% to 27.6%, hormone therapy from 14.1% to 18.8%, immunotherapy from 4.3% to 13.2%, and radiation therapy from 24.9% to 27.5%. The APCD increased the sensitivity of treatment variables compared with the abstraction gold standard. Notably, sensitivity of hormonal therapy for breast cancer increased from 78.6% to 95.2% when augmented with APCD claims data. However, the APCD alone did not achieve as high specificity for treatment data as did the data collected through traditional registry methods. CONCLUSIONS: This is the first study, to our knowledge, showing that linking cancer registry data with a statewide claims database that covers multiple insurance companies improves cancer treatment data collection. Linking of cancer registry and APCD data can improve comprehensiveness of cancer registry treatment data.

Descriptive Usability Study of CirrODS: Clinical Decision and Workflow Support Tool for Management of Patients With Cirrhosis.

BACKGROUND: There are gaps in delivering evidence-based care for patients with chronic liver disease and cirrhosis. OBJECTIVE: Our objective was to use interactive user-centered design methods to develop the Cirrhosis Order Set and Clinical Decision Support (CirrODS) tool in order to improve clinical decision-making and workflow. METHODS: Two work groups were convened with clinicians, user experience designers, human factors and health services researchers, and information technologists to create user interface designs. CirrODS prototypes underwent several rounds of formative design. Physicians (n=20) at three hospitals were provided with clinical scenarios of patients with cirrhosis, and the admission orders made with and without the CirrODS tool were compared. The physicians rated their experience using CirrODS and provided comments, which we coded into categories and themes. We assessed the safety, usability, and quality of CirrODS using qualitative and quantitative methods. RESULTS: We created an interactive CirrODS prototype that displays an alert when existing electronic data indicate a patient is at risk for cirrhosis. The tool consists of two primary frames, presenting relevant patient data and allowing recommended evidence-based tests and treatments to be ordered and categorized. Physicians viewed the tool positively and suggested that it would be most useful at the time of admission. When using the tool, the clinicians placed fewer orders than they placed when not using the tool, but more of the orders placed were considered to be high priority when the tool was used than when it was not used. The physicians' ratings of CirrODS indicated above average usability. CONCLUSIONS: We developed a novel Web-based combined clinical decision-making and workflow support tool to alert and assist clinicians caring for patients with cirrhosis. Further studies are underway to assess the impact on quality of care for patients with cirrhosis in actual practice.

Linkage between Utah All Payers Claims Database and Central Cancer Registry.

OBJECTIVE: To evaluate the linkage of claims from the Utah All Payers Claims Database (APCD) and Utah Cancer Registry (UCR). DATA SOURCES: Secondary data from 2013 and 2014 Utah APCD and 2013 UCR cases. STUDY DESIGN: This is a descriptive analysis of the quality of linkage between APCD claims data and cancer registry cases. DATA COLLECTION/EXTRACTION METHODS: We used the LinkPlus software to link Utah APCD and UCR data. PRINCIPAL FINDINGS: We were able to link 82.4 percent (9441/11 453) of the UCR reportable cancer cases with APCD claims. Of those linked, 66 percent were perfect matches. CONCLUSIONS: The quality of identifiers is high, evidence that claims data can potentially supplement cancer registry data for use in research.

Development of a cardiac-centered frailty ontology.

BACKGROUND: A Cardiac-centered Frailty Ontology can be an important foundation for using NLP to assess patient frailty. Frailty is an important consideration when making patient treatment decisions, particularly in older adults, those with a cardiac diagnosis, or when major surgery is a consideration. Clinicians often report patient's frailty in progress notes and other documentation. Frailty is recorded in many different ways in patient records and many different validated frailty-measuring instruments are available, with little consistency across instruments. We specifically explored concepts relevant to decisions regarding cardiac interventions. We based our work on text found in a large corpus of clinical notes from the Department of Veterans Affairs (VA) national Electronic Health Record (EHR) database. RESULTS: The full ontology has 156 concepts, with 246 terms. It includes 86 concepts we expect to find in clinical documents, with 12 qualifier values. The remaining 58 concepts represent hierarchical groups (e.g., physical function findings). Our top-level class is clinical finding, which has children clinical history finding, instrument finding, and physical examination finding, reflecting the OGMS definition of clinical finding. Instrument finding is any score found for the existing frailty instruments. Within our ontology, we used SNOMED-CT concepts where possible. Some of the 86 concepts we expect to find in clinical documents are associated with the properties like ability interpretation. The concept ability to walk can either be able, assisted or unable. Each concept-property level pairing gets a different frailty score. Each scored concept received three scores: a frailty score, a relevance to cardiac decisions score, and a likelihood of resolving after the recommended intervention score. The ontology includes the relationship between scores from ten frailty instruments and frailty as assessed using ontology concepts. It also included rules for mapping ontology elements to instrument items for three common frailty assessment instruments. Ontology elements are used in two clinical NLP systems. CONCLUSIONS: We developed and validated a Cardiac-centered Frailty Ontology, which is a machine-interoperable description of frailty that reflects all the areas that clinicians consider when deciding which cardiac intervention will best serve the patient as well as frailty indications generally relevant to medical decisions. The ontology owl file is available on Bioportal at http://bioportal.bioontology.org/ontologies/CCFO .

Application of contextual design methods to inform targeted clinical decision support interventions in sub-specialty care environments.

BACKGROUND & OBJECTIVES: In healthcare, the routine use of evidence-based specialty care management plans is mixed. Targeted computerized clinical decision support (CCDS) interventions can improve physician adherence, but adoption depends on CCDS' 'fit' within clinical work. We analyzed clinical work in outpatient and inpatient settings as a basis for developing guidelines for optimizing CCDS design. METHODS: The contextual design approach guided data collection, collation and analysis. Forty (40) consenting physicians were observed and interviewed in general internal medicine inpatient units and gastroenterology (GI) outpatient clinics at two academic medical centers. Data were collated using interpretive debriefing, and consolidated using thematic analysis and three work modeling approaches (communication flow, sequence and artifact models). RESULTS: Twenty-six consenting physicians were observed at Site A and 14 at Site B. Observations included attending (33%) and resident physicians. During research team debriefings, 220 of 341 unique topics were categorized into 5 CCDS-relevant themes. Resident physicians relied on patient assessment & planning processes to support their roles as communication and coordination hubs within the medical team. Artifact analysis further elucidated the evolution of assessment and planning over work shifts. CONCLUSIONS: The usefulness of CCDS tools may be enhanced in clinical care if the design: 1) accounts for clinical work that is distributed across people, space, and time; 2) targets communication and coordination hubs (specific roles) that can amplify the usefulness of CCDS interventions; 3) integrates CCDS with early clinical assessment & planning processes; and 4) provides CCDS in both electronic & hardcopy formats. These requirements provide a research agenda for future research in clinician-CCDS integration.
