RESUMO
BACKGROUND: The effectiveness of telemedicine by a patient's own primary care provider (PCP) versus another available PCP is understudied. OBJECTIVE: Examine the association between primary care visit modality with timeliness and follow-up in-person healthcare, including variation by visits with the patient's own PCP versus another PCP. DESIGN AND PARTICIPANTS: Cohort study including primary care visits in a large, integrated delivery system in 2022. MEASURES: Outcomes included timeliness (visit completed within 7 days of scheduling) and in-person follow-up (PCP visits, emergency department (ED) visits, hospitalizations) within 7 days of the index PCP visit. Logistic regression measured the association between visit modality (in-person, video, and audio-only telemedicine) with the patient's own PCP or another PCP and outcomes, adjusting for characteristics. KEY RESULTS: Among 4,817,317 primary care visits, 59% were in-person, 27% audio-only, and 14% video telemedicine. Most (71.3%) were with the patient's own PCP. Telemedicine visits were timelier, with modality having a larger association for visits with patient's own PCP versus another PCP (P < 0.001). For visits with patient's own PCPs, return office visit rates were 1.2% for in-person, 5.3% for video, and 6.1% for audio-only. For another PCP, rates were 2.2% for in-person, 7.3% for video, and 8.1% for audio. Follow-up ED visits ranged from 1.4% (in-person) to 1.6% (audio-only) with own PCP, compared to 1.9% (in-person) to 2.3% (audio-only) with another PCP. Differences in return office and ED visits between in-person and telemedicine were larger for visits with another PCP compared to their own PCP (P < 0.001). Follow-up hospitalizations were rare, ranging from 0.19% (in-person with own PCP) to 0.32% (video with another PCP). CONCLUSION: Differences in return office and ED visits between in-person and telemedicine were larger when patients saw a less familiar PCP compared to their own PCP, reinforcing the importance of care continuity.
RESUMO
BACKGROUND: The pandemic rapidly expanded telemedicine, which has persisted as a widely available primary care modality. The uptake of telemedicine among people with dementia specifically in the primary care setting, who have more complex care needs but also benefit from more accessible primary care, is unknown. OBJECTIVE: Among people with dementia, assess uptake of telemedicine-based primary care in the post-pandemic period and determine associations with key socio-demographic characteristics. DESIGN: Retrospective observational study. SUBJECTS: People with dementia at UCSF and Kaiser Permanente Northern CA (KPNC) with at least one primary care encounter in pre- (3/1/2019-2/29/2020) or post-COVID (3/1/2021-2/28/2022) periods, post-COVID sample: N= 419 individuals (UCSF), N=18,037 (KPNC). MAIN MEASURES: Encounter modality: in-person, video telemedicine, or telephone telemedicine. Focal socio-demographic characteristics: age, limited English proficiency, socioeconomic status, driving distance to clinic, and caregiver at encounter. KEY RESULTS: There was a large increase in telemedicine among people with dementia in the post-pandemic period at both sites. At KPNC, those with only in-person primary care visits shrunk from 60.47% (pre) to 26.95% (post). At UCSF, the change was even greater: 98.99% to 35.08%. Across both sites, the only measure significantly associated with use of telemedicine was greater driving distance from home to clinic. At KPNC, those over age 90 were most likely to use telemedicine while patients with limited English proficiency and those with a caregiver at the encounter used telemedicine at lower levels. The relationships were similar at UCSF but not statistically significant. CONCLUSIONS: Telemedicine use is high for people with dementia in the primary care setting in the post-pandemic period. Those with longer drives to clinic and the oldest patients were most likely to use telemedicine, likely due to challenges traveling to appointments. Still, not all people with dementia used telemedicine equally-particularly those with limited English proficiency.
RESUMO
BACKGROUND: Telemedicine use expanded greatly during the COVID-19 pandemic. More data is needed to understand how this shift may impact other venues of acute care delivery. OBJECTIVE: We evaluate the association of visit modality (telephone, video, or office) and downstream emergency department (ED) and hospital visits among primary care visits for acute, time-sensitive conditions. DESIGN: Observational study of patient-scheduled primary care telemedicine and office visits for acute conditions (cardiac, gastrointestinal, neurologic, musculoskeletal, and head and neck) in a large, integrated healthcare delivery system. PARTICIPANTS: Adults with a new self-booked primary care appointment for an eligible acute condition from January 1, 2022, to December 31, 2022 (with no primary care, ED, or hospital visits in prior 30 days). INTERVENTIONS: Visit modality, including office, video, or telephone. MAIN MEASURES: Seven-day ED and hospital utilization, adjusted for patient and visit characteristics. KEY RESULTS: Among 258,958 primary care visits by 239,240 adult patients, 57.7% were telemedicine visits; of these, 72.4% were telephone and 27.6% were video. Telephone visits were the timeliest, with over 70% of visits scheduled within 1 day of booking. Rates of 7-day ED utilization were low, and varied by condition group, with cardiac visits having the highest rates (4.8%) and musculoskeletal visits having the lowest (0.8%). There was less than a 1% absolute difference in ED use by visit modality for all condition types; however, telephone visits were associated with slightly higher rates than video visits. The 7-day hospitalization rate was less than 1% and observed between visit type differences varied by clinical condition. CONCLUSIONS: Among office, telephone, and video visits in primary care for potentially high-risk, time-sensitive conditions, downstream ED and hospital use were uncommon. ED utilization was lower for video visits than telephone visits, although telephone visits were timelier and may offer a safe and accessible option for acute care.
RESUMO
BACKGROUND: Despite greater care needs, patients with limited English proficiency (LEP) are less likely to use telemedicine. Given the expansion of telemedicine since the COVID-19 pandemic, identifying ways to narrow the telemedicine care gaps experienced by people with LEP is essential. OBJECTIVE: Examine the telemedicine experiences of Mandarin-speaking adults with LEP, with a focus on perceived differences between in-person care, video, and telephone telemedicine. PARTICIPANTS: Random sample of Kaiser Permanente Northern California (KPNC) members who completed at least one primary care telemedicine visit in August 2021, aged 40 years or older, and had electronic health record-documented need for a Mandarin interpreter. The sample was stratified by telemedicine visit type (video or phone). APPROACH: Semi-structured Mandarin-language telephone interviews with a bilingual and bicultural research assistant collected patient experiences with telemedicine in general and telemedicine visits assisted by interpreters. Two coders used rapid qualitative analytic techniques to capture themes. KEY RESULTS: Among 20 respondents (n = 12, 60% women) age 41-81, all had prior experience with telephone visits and 17 (85%) had experience with video visits. Patients reported three major themes: (1) communication, language skills, and how patience impacts care quality; (2) the importance of matching patient preferences on communication modality; and (3) the need for comprehensive language services throughout the continuum of healthcare delivery. CONCLUSION: Mandarin-speaking adults with LEP see telemedicine as a convenient and necessary service. Issues with healthcare providers' and interpreters' communication skills and impatience were common. The lack of wrap-around language-concordant care beyond the visit itself was cited as an ongoing and unaddressed care barrier. Healthcare provider and interpreter training is important, as is availability of personalized and comprehensive language services in promoting patient autonomy, alleviating the burden on patients' families, and thus ensuring equitable healthcare access.
RESUMO
BACKGROUND: Invasive bacterial infections (IBIs) in febrile infants are rare but potentially devastating. We aimed to derive and validate a predictive model for IBI among febrile infants age 7-60 days. METHODS: Data were abstracted retrospectively from electronic records of 37 emergency departments (EDs) for infants with a measured temperature >=100.4 F who underwent an ED evaluation with blood and urine cultures. Models to predict IBI were developed and validated respectively using a random 80/20 dataset split, including 10-fold cross-validation. We used precision recall curves as the classification metric. RESULTS: Of 4411 eligible infants with a mean age of 37 days, 29% had characteristics that would likely have excluded them from existing risk stratification protocols. There were 196 patients with IBI (4.4%), including 43 (1.0%) with bacterial meningitis. Analytic approaches varied in performance characteristics (precision recall range 0.04-0.29, area under the curve range 0.5-0.84), with the XGBoost model demonstrating the best performance (0.29, 0.84). The five most important variables were serum white blood count, maximum temperature, absolute neutrophil count, absolute band count, and age in days. CONCLUSION: A machine learning model (XGBoost) demonstrated the best performance in predicting a rare outcome among febrile infants, including those excluded from existing algorithms. IMPACT: Several models for the risk stratification of febrile infants have been developed. There is a need for a preferred comprehensive model free from limitations and algorithm exclusions that accurately predicts IBIs. This is the first study to derive an all-inclusive predictive model for febrile infants aged 7-60 days in a community ED sample with IBI as a primary outcome. This machine learning model demonstrates potential for clinical utility in predicting IBI.
RESUMO
BACKGROUND: During the first nine months of the COVID-19 emergency, patients were encouraged to use virtual versus clinic visits if in-person care was not deemed necessary by clinical staff. This study examined the association of spoken language preference and ethnicity with use of video versus phone virtual visits by US Latino and Chinese adult patients who got care in the same healthcare system. METHODS: We analyzed electronic health record data for four groups of adults aged 26-85y who had ≥ 1 primary or specialty care outpatient clinician visits during April-December 2020: 80,869 Latino adults preferring Spanish (LEP Latino); 214,765 Latino adults preferring English (non-LEP Latino); 23,430 Chinese adults preferring a Chinese dialect (LEP Chinese); and 49,710 Chinese adults preferring English (non-LEP Chinese). Prevalence of the following utilization outcomes were compared by language preference (LEP/non-LEP) within ethnicity and by ethnicity within language preference for four age subgroups (26-39y, 40-64y, 65-75y, and 76-85y): ≥ 1 virtual (video or phone) visit, ≥ 1 video visit, ≥ 1 phone visit, ≥ 1 clinic visit, video visits only, and phone visits only. We also compared ethnicity x language group differences within age subgroups using absolute difference and adjusted prevalence ratios derived from modified log-Poisson regression models that controlled for age and sex. RESULTS: Among virtual users, LEP Latino and Chinese adults were significantly less likely to use video visits and more likely to use phone visits than non-LEP Latino and Chinese adults in the same age strata. The LEP/non-LEP difference in video visit use was significantly larger among Latino than Chinese patients, with no similar ethnic group difference observed for phone visits. Within the LEP and non-LEP language groups, Chinese adults were significantly more likely than Latino adults to use video visits and less likely to use phone visits. CONCLUSIONS: During the first nine months of the COVID-19 pandemic, uptake of video and phone virtual visits by Latino and Chinese adults significantly differed by LEP/non-LEP status within ethnicity and by ethnicity within LEP/non-LEP language group. These findings underscore the importance of disaggregating data by ethnicity and language preference when attempting to understand and study patient use of different virtual visit modalities.

BACKGROUND: Beyond initial COVID-19 pandemic emergency expansions of telemedicine use, it is unclear how well primary care telemedicine addresses patients' needs. OBJECTIVE: To compare treatment and follow-up visits (office, emergency department, hospitalization) between primary care video or telephone telemedicine and in-person office visits. DESIGN: Retrospective design based on administrative and electronic health record (EHR) data. SETTING: Large, integrated health care delivery system with more than 1300 primary care providers, between April 2021 and December 2021 (including the COVID-19 pandemic Delta wave). PATIENTS: 1 589 014 adult patients; 26.5% were aged 65 years or older, 54.9% were female, 22.2% were Asian, 7.4% were Black, 22.3% were Hispanic, 46.5% were White, 21.5% lived in neighborhoods with lower socioeconomic status, and 31.8% had a chronic health condition. MEASUREMENTS: Treatment outcomes included medication or antibiotic prescribing and laboratory or imaging ordering. Follow-up visits included in-person visits to the primary care office or emergency department or hospitalization within 7 days. Outcomes were adjusted for sociodemographic and clinical characteristics overall and stratified by clinical area (abdominal pain, gastrointestinal concerns, back pain, dermatologic concerns, musculoskeletal pain, routine care, hypertension or diabetes, and mental health). RESULTS: Of 2 357 598 primary care visits, 50.8% used telemedicine (19.5% video and 31.3% telephone). After adjustment, medications were prescribed in 46.8% of office visits, 38.4% of video visits, and 34.6% of telephone visits. After the visit, 1.3% of in-person visits, 6.2% of video visits, and 7.6% of telephone visits had a 7-day return in-person primary care visit; 1.6% of in-person visits, 1.8% of video visits, and 2.1% of telephone visits were followed by an emergency department visit. Differences in follow-up office visits were largest after index office versus telephone visits for acute pain conditions and smallest for mental health. LIMITATIONS: In the study setting, telemedicine is fully integrated with ongoing EHRs and with clinicians, and the study examines an insured population during the late COVID-19 pandemic period. Observational comparison lacks detailed severity or symptom measures. Follow-up was limited to 7 days. Clinical area categorization uses diagnosis code rather than symptom. CONCLUSION: In-person return visits were somewhat higher after telemedicine compared with in-person primary care visits but varied by specific clinical condition.

BACKGROUND: Patient perceptions of primary care telephone and video telemedicine and whether COVID-19 pandemic-related telemedicine exposure shifted patients' visit preference is unknown. OBJECTIVES: We examined patient surveys to understand the health care experience of patients seeking primary care through telemedicine and how patients expected their preferences to shift as a result of the COVID-19 pandemic. RESEARCH DESIGN/SUBJECTS: In an integrated delivery system that shifted to a "telemedicine-first" health care model during the COVID-19 pandemic, we sampled monthly and collected 1000 surveys from adults with primary care telemedicine visits scheduled through the online patient portal between 3/16/2020 and 10/31/2020. MEASURES: Participants reported their preferred primary care visit modality (telephone, video, or in-person visits) across 3 time points: before, during and (hypothetically) after the COVID-19 pandemic, and reported their general assessment of primary care visits during the pandemic. RESULTS: The majority of participants preferred in-person visits before (69%) and after the COVID-19 pandemic (57%). However, most participants reported a preference for telemedicine visits during the pandemic and continue to prefer telemedicine visits at a 12% higher rate post-pandemic. Many participants (63%) expressed interest in using telemedicine at least some of the time. Among participants reporting a recent telemedicine visit, 85% agreed that the visit addressed their health needs. CONCLUSION: As primary care visit modality preferences continue to evolve, patients anticipate that they will continue to prefer telemedicine visits, both video and telephone, at an increased rate than before the COVID-19 pandemic.

BACKGROUND: Telemedicine's dramatic increase during the COVID-19 pandemic elevates the importance of addressing patient-care gaps in telemedicine, especially for patients with limited English proficiency. OBJECTIVE: To examine the associations of patient language and patient-provider language concordance with telemedicine visit type (video versus telephone visit). DESIGN: Cross-sectional automated data study of patient-scheduled primary care telemedicine appointments from March 16, 2020, to October 31, 2020. SETTING: Northern California integrated healthcare delivery system. PARTICIPANTS: All 22,427 completed primary care telemedicine visits scheduled by 13,764 patients with limited English proficiency via the patient portal. MEASUREMENTS: Cross-sectional association of electronic health record-documented patient language (Spanish as referent) and patient-provider language concordance with patients' choice of a video (versus telephone) visit, accounting for patient sociodemographics, technology access, and technology familiarity factors. RESULTS: Of all patient-scheduled visits, 34.5% (n = 7747) were video visits. The top three patient languages were Spanish (42.4%), Cantonese (16.9%), and Mandarin (10.3%). Adjusting for sociodemographic and technology access and familiarity factors and compared to patients speaking Spanish, video visit use was higher among patients speaking Cantonese (OR = 1.34, 95% CI: 1.18-1.52), Mandarin (OR = 1.33, 95% CI: 1.16-1.52), or Vietnamese (OR = 1.27, 95% CI: 1.09-1.47), but lower among patients speaking Punjabi (OR = 0.75, 95% CI: 0.75, 0.62-0.91). Language concordance was associated with lower video visit use (OR = 0.86, 95% CI: 0.80-0.93) and moderated associations of speaking Spanish, Cantonese, and Korean with video visit use. In addition, for all language groups, those with prior video visit use were more likely to re-use video visits compared to those with no prior use (p < .05 for all languages except Hindi with p = 0.06). CONCLUSIONS: Among linguistically diverse patients with limited English proficiency, video telemedicine use differed by specific language. Disaggregating patient subpopulation data is necessary for identifying those at greatest risk of being negatively impacted by the digital divide.

STUDY OBJECTIVE: Some patients with acute pulmonary embolism (PE) will suffer adverse clinical outcomes despite being low risk by clinical decision rules. Emergency physician decisionmaking processes regarding which low-risk patients require hospitalization are unclear. Higher heart rate (HR) or embolic burden may increase short-term mortality risk, and we hypothesized that these variables would be associated with an increased likelihood of hospitalization for patients designated as low risk by the PE Severity Index. METHODS: This was a retrospective cohort study of 461 adult emergency department (ED) patients with a PE Severity Index score of fewer than 86 points. Primary exposures were the highest observed ED HR, most proximal embolus location (proximal vs distal), and embolism laterality (bilateral vs unilateral PE). The primary outcome was hospitalization. RESULTS: Of 461 patients meeting inclusion criteria, most (57.5%) were hospitalized, 2 patients (0.4%) died within 30 days, and 142 (30.8%) patients were at elevated risk by other criteria (Hestia criteria or biochemical/radiographic right ventricular dysfunction). Variablesassociated with an increased likelihood of admission were highest observed ED HR of ≥110 beats/minute (vs HR <90 beats/min) (adjusted odds ratio [aOR] 3.11; 95% confidence interval [CI] 1.07 to 9.57), highest ED HR 90 to 109 (aOR 2.03; 95% CI 1.18-3.50) and bilateral PE (aOR 1.92; 95% CI 1.13 to 3.27). Proximal embolus location was not associated with the likelihood of hospitalization (aOR 1.19; 95% CI 0.71 to 2.00). CONCLUSIONS: Most patients were hospitalized, often with recognizable high-risk characteristics not accounted for by the PE Severity Index. Highest ED HR of ≥90 beats/min and bilateral PE were associated with a physician's decision for hospitalization.

INTRODUCTION: Computed tomography (CT) is performed in over 90% of patients diagnosed with ureteral stones, but only 10% of patients presenting to the emergency department (ED) with acute flank pain are hospitalized for a clinically important stone or non-stone diagnosis. Hydronephrosis can be accurately detected using point-of-care ultrasound and is a key predictor of ureteral stone and risk of subsequent complications. The absence of hydronephrosis is insufficient to exclude a stone. We created a sensitive clinical decision rule to predict clinically important ureteral stones. We hypothesized that this rule could identify patients at low risk for this outcome. METHODS: We conducted a retrospective cohort study in a random sample of 4000 adults who presented to one of 21 Kaiser Permanente Northern California EDs and underwent a CT for suspected ureteral stone from 1/1/2016 to 12/31/2020. The primary outcome was clinically important stone, defined as stone resulting in hospitalization or urologic procedure within 60 days. We used recursive partition analysis to generate a clinical decision rule predicting the outcome. We estimated the C-statistic (area under the curve), plotted the receiver operating characteristic (ROC) curve for the model, and calculated sensitivity, specificity, and predictive values of the model based on a risk threshold of 2%. RESULTS: Among 4000 patients, 354 (8.9%) had a clinically important stone. Our partition model resulted in four terminal nodes with risks ranging from 0.4% to 21.8%. The area under the ROC curve was 0.81 (95% CI 0.80, 0.83). Using a 2% risk cut point, a clinical decision tree including hydronephrosis, hematuria, and a history of prior stones predicted complicated stones with sensitivity 95.5% (95% CI 92.8%-97.4%), specificity 59.9% (95% CI 58.3%-61.5%), positive predictive value 18.8% (95% CI 18.1%-19.5%), and negative predictive value 99.3% (95% CI 98.8%-99.6%). CONCLUSIONS: Application of this clinical decision rule to imaging decisions would have led to 63% fewer CT scans with a miss rate of 0.4%. A limitation was the application of our decision rule only to patients who underwent CT for suspected ureteral stone. Thus, this rule would not apply to patients who were thought to have ureteral colic but did not receive a CT because ultrasound or history were sufficient for diagnosis. These results could inform future prospective validation studies.

BACKGROUND: Practice guidelines recommend that patients with intracerebral hemorrhage (ICH) be treated in units with acute neuroscience care experience. However, most hospitals in the United States lack this degree of specialization. We sought to examine outcome differences for patients with nontraumatic ICH presenting to centers with and without advanced neuroscience care specialization. METHODS: This was a retrospective study of adult patients presenting with nontraumatic ICH between 1/1/2011 and 9/30/2020 across 21 medical centers within Kaiser Permanente Northern California, an integrated care system that employs a "hub-and-spoke" model of neuroscience care in which two centers service as neuroscience "hubs" and the remaining 19 centers service as referral "spokes." Patients presenting to spokes can receive remote consultation (including image review) by neurosurgical or neurointensive care specialists located at hubs. The primary outcome was 90-day mortality. We used hierarchical logistic regression, adjusting for ICH score components, comorbidities, and demographics, to test a hypothesis that initial presentation to a spoke medical center was noninferior to hub presentation [defined as an odds ratio (OR) with an upper 95% confidence interval (CI) limit of 1.24 or less]. RESULTS: A total of 6978 patients were included, with 6170 (88%) initially presenting to spoke medical centers. The unadjusted 90-day mortality for patients initially presenting to spoke versus hub medical centers was 32.2% and 32.7%, respectively. In adjusted analysis, presentation to a spoke medical center was neither noninferior nor inferior for 90-day mortality risk (OR 1.21, 95% CI 0.84-1.74). Sensitivity analysis excluding patients admitted to general wards or lacking continuous health plan insurance during the follow-up period trended closer to a noninferior result (OR 0.99, 95% CI 0.69-1.44). CONCLUSIONS: Within an integrated "hub-and-spoke" neuroscience care model, the risk of 90-day mortality following initial presentation with nontraumatic ICH to a spoke medical center was not conclusively noninferior compared with initial presentation to a hub medical center. However, there was also no indication that care for selected patients with nontraumatic ICH within medical centers lacking advanced neuroscience specialization resulted in significantly inferior outcomes. This finding may support the safety and efficiency of a "hub-and-spoke" care model for patients with nontraumatic ICH, although additional investigations are warranted.

Emergency department (ED) providers play a critical role in the stabilization and diagnostic evaluation of patients presenting with acute heart failure (AHF), and EDs are key areas for establishing current best practices and future considerations for the disposition of and decision making for patients with AHF. These elements include accurate risk assessment; response to initial treatment and shared decision making concerning optimal venue of care; reframing of physicians' risk perceptions for patients presenting with AHF; exploration of alternative venues of care beyond hospitalization; population-level changes in demographics, management and outcomes of HF patients; development and testing of data-driven pathways to assist with disposition decisions in the ED; and suggested outcomes for measuring success.

BACKGROUND: The management and outcomes of patients diagnosed with acute pulmonary embolism in primary care have not been characterized. OBJECTIVE: To describe 30-day outcomes stratified by initial site-of-care decisions DESIGN: Multicenter retrospective cohort study PARTICIPANTS: Adults diagnosed with acute pulmonary embolism in primary care in a large, diverse community-based US health system (2013-2019) MAIN MEASURES: The primary outcome was a composite of 30-day serious adverse events (recurrent venous thromboembolism, major bleeding, and all-cause mortality). The secondary outcome was 7-day pulmonary embolism-related hospitalization, either initial or delayed. KEY RESULTS: Among 652 patient encounters (from 646 patients), median age was 64 years; 51.5% were male and 70.7% identified as non-Hispanic white. Overall, 134 cases (20.6%) were sent home from primary care and 518 cases (79.4%) were initially referred to the emergency department (ED) or hospital. Among the referred, 196 (37.8%) were discharged home from the ED without events. Eight patients (1.2%; 95% CI 0.5-2.4%) experienced a 30-day serious adverse event: 4 venous thromboemboli (0.6%), 1 major bleed (0.2%), and 3 deaths (0.5%). Seven of these patients were initially hospitalized, and 1 had been sent home from primary care. All 3 deaths occurred in patients with known metastatic cancer initially referred to the ED, hospitalized, then enrolled in hospice following discharge. Overall, 328 patients (50.3%) were hospitalized within 7 days: 322 at the time of the index diagnosis and 6 following initial outpatient management (4 clinic-only and 2 clinic-plus-ED patients). CONCLUSIONS: Patients diagnosed with acute pulmonary embolism in this primary care setting uncommonly experienced 30-day adverse events, regardless of initial site-of-care decisions. Over 20% were managed comprehensively by primary care. Delayed 7-day pulmonary embolism-related hospitalization was rare among the 51% treated as outpatients. Primary care management of acute pulmonary embolism appears to be safe and could have implications for cost-effectiveness and patient care experience.

INTRODUCTION: Telemedicine is increasingly relied upon for care delivery in primary care, but the impact of visit type on clinical ordering behavior is uncertain. METHODS: Within Kaiser Permanente Northern California, we identified patients who self-scheduled and completed telemedicine encounters with their personal primary care provider or another available primary care provider in the same medical group, between April 1st, 2020, and October 31st, 2020, while physical distancing restrictions for COVID-19 were in place. We collected patient sociodemographic and clinical characteristics, measures of technology access, and categorized the most common primary encounter diagnoses. We measured proportions of patient-scheduled video versus telephone visits for each of eight diagnosis groups (Skin & Soft Tissue, Musculoskeletal Pain, Back Pain, General Gastrointestinal, Hypertension & Diabetes, Mental Health, Upper Respiratory, and Abdominal Pain), and compared physician orders for medications, antibiotics, lab and imaging studies by visit type within each diagnosis group. RESULTS: There were 273,301 included encounters, with 86,676 (41.5%) video visits and 122,051 (58.5%) telephone visits. Of the diagnosis groups, Skin & Soft Tissue conditions had the highest proportion of video visits (59.7%), while Mental Health conditions had the highest proportion of telephone visits (71.1%). After adjusting for covariates, the overall rates of medication orders (46.6% vs. 44.5%), imaging orders (17.3% vs. 14.9%), lab orders (19.5% vs. 17.2%), and antibiotic orders (7.5% vs. 5.2%) were higher during video visits as compared to telephone visits (p < 0.05). The largest difference within diagnosis groups was for Skin & Soft Tissue conditions, where the rate of medication orders was 9.1% higher than during video visits than telephone visits (45.5% vs. 36.5%, p < 0.05). CONCLUSIONS: We observed statistically significant differences in clinician orders by visit type during telemedicine encounters for common primary care conditions. Our findings suggest that, for certain conditions, visual information conveyed during video visits may promote clinical work-up and treatment.

Introduction: Telemedicine could increase timely access to primary care-a key dimension of care quality. Methods: Among patient-scheduled appointments with their own primary care providers using the online portal in a large integrated health care delivery system, we measured the association between visit type (telemedicine or in-person) and appointment timeliness. We calculated the calendar days between the scheduling date and the actual appointment time. Results: Overall, 2,178,440 primary care visits were scheduled and 14% were done through telemedicine. The mean calendar days between the scheduling and the appointment time were 1.80 for telephone visits, 2.29 for video visits, and 3.52 for in-person visits. After multivariate adjustment, 66.61% (confidence interval [95% CI]: 66.44-66.79) of telephone visits, 56.58% (95% CI: 55.90-57.27) of video visits, and 46.49% (95% CI: 46.42-46.57) of in-person visits were scheduled to occur within 1 day of making the appointment. Conclusions: In a setting with comparable in-person and telemedicine scheduling availability, choosing telemedicine was associated with more timely access to primary care.

BACKGROUND: Despite the existing research exploring caregiver burden in adult psychosis, few studies have examined the experience of providing care to children diagnosed with psychotic disorders (PDs) and those identified as having clinical high risk for psychosis (CHR-P). OBJECTIVE: This study measured the level of burden in caregivers of children with PD and CHR-P and examined associated risk factors, including social support, caregiver-child relationship, severity of illness, and frequency of psychiatric hospitalizations. METHODS: A total of 56 caregivers completed validated measures and provided demographic information. Measures included the Zarit Burden Interview, the Multidimensional Scale of Perceived Social Support, the Behavior Assessment System for Children, Third Edition, Parenting Relationship Questionnaire-Child and Adolescent Form (BASC-3 PRQ-CA), and the Clinical Global Impression-Severity scale. RESULTS: The majority of caregivers were women (86%), mothers (84%), White (63%), married (66%), working full-time (50%), college-educated (79%), and whose mean age was 45.7 years (SD = 8.09). Nearly half of the caregivers (45%) reported a high level of caregiver burden, 39% rated their burden in the mild to moderate range, and 16% reported little to no burden. There was no significant difference in mean burden between PD and CHR-P groups. Higher caregiver burden was associated with lower levels of social support (r = -.408, p = .002), lower levels of parenting confidence (r = -.514, p < .001), higher levels of relational frustration (r = .612, p < .001), and higher severity of illness (r = .316 p = .025). CONCLUSIONS: These findings underscore the critical unmet need for support for caregivers of children with PD and CHR-P. Applications to clinical practice are discussed.
RESUMO
STUDY OBJECTIVE: We use variables from a recently derived acute heart failure risk-stratification rule (STRATIFY) as a basis to develop and optimize risk prediction using additional patient clinical data from electronic health records and machine-learning models. METHODS: Using a retrospective cohort design, we identified all emergency department (ED) visits for acute heart failure between January 1, 2017, and December 31, 2018, among adult health plan members of a large system with 21 EDs. The primary outcome was any 30-day serious adverse event, including death, cardiopulmonary resuscitation, balloon-pump insertion, intubation, new dialysis, myocardial infarction, or coronary revascularization. Starting with the 13 variables from the STRATIFY rule (base model), we tested whether predictive accuracy in a different population could be enhanced with additional electronic health record-based variables or machine-learning approaches (compared with logistic regression). We calculated our derived model area under the curve (AUC), calculated test characteristics, and assessed admission rates across risk categories. RESULTS: Among 26,189 total ED encounters, mean patient age was 74 years, 51.7% were women, and 60.7% were white. The overall 30-day serious adverse event rate was 18.8%. The base model had an AUC of 0.76 (95% confidence interval 0.74 to 0.77). Incorporating additional variables led to improved accuracy with logistic regression (AUC 0.80; 95% confidence interval 0.79 to 0.82) and machine learning (AUC 0.85; 95% confidence interval 0.83 to 0.86). We found that 11.1%, 25.7%, and 48.9% of the study population had predicted serious adverse event risk of less than or equal to 3%, less than or equal to 5%, and less than or equal to 10%, respectively, and 28% of those with less than or equal to 3% risk were admitted. CONCLUSION: Use of a machine-learning model with additional variables improved 30-day risk prediction compared with conventional approaches.

STUDY OBJECTIVE: To assess trends over time in red blood cell (RBC) transfusion practice among emergency department (ED) patients with gastrointestinal (GI) bleeding within an integrated healthcare system, inclusive of 21 EDs. METHODS: Retrospective cohort of ED patients diagnosed with GI bleeding between July 1st, 2012 and September 30th, 2016. The primary outcome was receipt of an RBC transfusion in the ED. Secondary outcomes included 90-day rates of RBC transfusion, repeat ED visits, rehospitalization, and all-cause mortality. Logistic regression was used to obtain confounder-adjusted outcome rates. RESULTS: A total of 24,868 unique patient encounters were used for the primary analysis. The median hemoglobin level in the ED prior to RBC transfusion decreased from 7.5â¯g/dl to 6.9â¯g/dl in the first versus last twelve months of the study period (pâ¯<â¯0.0001). A small trend was observed in the overall adjusted rate of ED RBC transfusion (absolute quarterly change of -0.1%, R2â¯=â¯0.18, pâ¯=â¯0.0001) largely attributable to the subgroup of patients with hemoglobin nadirs between 7.0 and 9.9â¯g/dl (absolute quarterly change of -0.4%, R2â¯=â¯0.38, pâ¯<â¯0.0001). Rates of RBC transfusions through 90â¯days likewise decreased (absolute quarterly change of -0.4%, R2â¯=â¯0.85, pâ¯<â¯0.0001) with stable to decreased corresponding rates of repeat ED visits, rehospitalizations and mortality. CONCLUSION: Rates of ED RBC transfusion decreased over time among patients with GI bleeding, particularly in those with hemoglobin nadirs between 7.0 and 9.9â¯g/dl. These findings suggest that ED providers are willing to adopt evidence-based restrictive RBC transfusion recommendations for patients with GI bleeding.

BACKGROUND: A low (0-3) History, Electrocardiogram, Age, Risk factors and Troponin (HEART) score reliably identifies ED chest pain patients who are low risk for near-term major adverse cardiac events (MACE). To optimize sensitivity, many clinicians employ a modified HEART score by repeating troponin measurements and excluding patients with abnormal troponin values or ischemic electrocardiograms (ECGs). The residual MACE risk among patients with otherwise non-low (≥4) modified HEART scores is thus likely much lower than with non-low original HEART scores. OBJECTIVE: To explore residual 60-day MACE risks among patients with non-low modified HEART scores. METHODS: Secondary analysis of a retrospective cohort of ED patients presenting with chest pain to an integrated healthcare system between 2013 and 2015. Patients with serial troponin measurements within 6 h of ED arrival were considered for inclusion. Exclusions included an ischemic ECG, troponin values above the 99th percentile or a lack of continuous health plan coverage through the 60-day follow-up period. MACE was defined as a composite of myocardial infarction, cardiac arrest, cardiogenic shock or death. RESULTS: There were 22,976 study eligible patients encounters, 13,521 (59%) of which had non-low (≥4) modified HEART scores. The observed 60-day MACE risk among non-low HEART score patients was 2.0% (95% CI 1.8-2.3). When including all coronary revascularizations (MACE-R), the risk was 4.4% (95% CI 4.1-4.4). CONCLUSION: Risk of near-term MACE among patients with non-low modified HEART scores (excluding those with abnormal troponin or ischemic ECGs) appears to be much lower than in the original HEART score validation studies.
