Toward the Deimplementation of Computed Tomography Urogram for Patients With Low- to Intermediate-risk Microscopic Hematuria: A Mixed-method Study of Factors Influencing Continued Use. UROLOGY PRACTICE 2023; 10:511-519. [PMID: 37499130 PMCID: PMC10609652 DOI: 10.1097/upj.0000000000000429] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/08/2023] [Accepted: 06/16/2023] [Indexed: 07/29/2023]
Abstract
INTRODUCTION Citing high costs, limited diagnostic benefit, and ionizing radiation-associated risk from CT urogram, in 2020 the AUA revised its guidelines from recommending CT urogram for all patients with microscopic hematuria to a deintensified risk-stratified approach, including the deimplementation of low-value CT urogram (ie, not recommending CT urogram for patients with low- to intermediate-risk microscopic hematuria). Adherence to revised guidelines and reasons for continued low-value CT urogram are unknown. METHODS With the overarching objective of improving guideline implementation, we used a mixed-method convergent explanatory design with electronic health record data for a retrospective cohort at a single academic tertiary medical center in the southeastern United States and semistructured interviews with urology and nonurology providers to describe determinants of low-value CT urogram following guideline revision. RESULTS Of 391 patients with microscopic hematuria, 198 (51%) had a low-value CT urogram (136 [69%] pre-guideline revision, 62 [31%] postrevision). The odds of ordering a low-value CT urogram were lower after guideline revisions, but the change was not statistically significant (OR: 0.44, P = .08); odds were 1.89 higher (P = .06) among nonurology providers than urology providers, but the difference was not statistically significant. Provider interviews suggested low-value CT urogram related to nonurology providers' limited awareness of revised guidelines, the role of clinical judgment in microscopic hematuria evaluation, and professional and patient influences. CONCLUSIONS Our findings suggest low-value CT urogram deimplementation may be improved with guidelines and implementation support directed at both urology and nonurology providers and algorithms to support guideline-concordant microscopic hematuria evaluation approaches. Future studies should test these strategies.

Abstract
With rising health care costs, health systems have adopted alternative care models targeting high-need, high-cost patients to improve chronic disease management and population health. Intensive primary care teams may reduce health care utilization by tackling medical and psychosocial needs specific to this patient population. This study presents health care utilization trends from a high-intensity primary care program that employs a multidisciplinary team (including clinicians, psychologists, pharmacists, chaplaincy, and community health workers) and community partnerships. Using descriptive statistics and Poisson rates of differences, this study evaluates patient and utilization characteristics of those enrolled (n = 341) versus declined (n = 54) program participation from 2013 to 2020. Both enrolled and declined patients experienced significant reduction in emergency department and inpatient utilization, but differences between enrolled and declined patients were not statistically significant. Programs aimed at decreasing health care utilization for high-need, high-cost, medically complex patients may be best supported by interventions that simultaneously address social and behavioral health needs.

The Future of Community Outreach: Using Patient Portals to Provide Voter Resources during the Coronavirus Disease 2019 Pandemic. Appl Clin Inform 2023; 14:300-309. [PMID: 37075802 PMCID: PMC10115515 DOI: 10.1055/s-0043-1764380] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/03/2022] [Accepted: 01/23/2023] [Indexed: 04/21/2023] Open
Abstract
BACKGROUND During the coronavirus disease 2019 (COVID-19) pandemic, there was a concern for the 2020 general election becoming a superspreader event due to in-person voting. OBJECTIVES Our project addressed this concern by disseminating nonpartisan websites detailing safe voter options in the state of North Carolina to prevent community spread of the virus as much as possible. METHODS In this study, patient portals were used to disseminate a Research Electronic Data Capture survey containing embedded links to voter resources including nonpartisan websites discussing voting options. The survey also asked for demographic data and sentiments regarding the resources provided. Quick response (QR) codes with the survey link were also placed in the clinics during the study period. RESULTS The survey was sent to 14,842 patients who had at least one patient encounter in the past 12 months at one of three General Internal Medicine clinics at Atrium Health Wake Forest Baptist. Survey participation through both the patient portals and QR codes was assessed. Patient sentiments toward the voter resources in regard to (1) interest and (2) perceived helpfulness were collected in the survey. In total, 738 (4.99%) patients filled out the survey. Eighty-seven percent of survey respondents reported that the voter resources were helpful. Significantly more black patients than white (29.3 vs. 18.2, p < 0.05) voiced interest in voter resources. There was no statistical significance across gender or reported comorbidities. CONCLUSION Multicultural, underserved, and underinsured patients perceived the most benefit. During public health crises, patient portal messages can be used to bridge information gaps and promote better health outcomes in a timely and effective manner.

Telephone-Only Visits Preserved Hepatocellular Cancer Screening Rates in Patients with Cirrhosis Early in the COVID-19 Pandemic. Dig Dis Sci 2022; 68:1791-1796. [PMID: 36562886 PMCID: PMC9780624 DOI: 10.1007/s10620-022-07786-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/01/2022] [Accepted: 12/05/2022] [Indexed: 12/24/2022]
Abstract
BACKGROUND The coronavirus 2019 (COVID-19) pandemic required an immediate and large-scale transition to telemedicine. Telemedicine includes phone visits and video visits. Studies suggest that hepatocellular cancer (HCC) screening rates fell at the beginning of the COVID-19 pandemic. If left unaddressed, HCC morbidity/mortality may increase following the pandemic due to inadequate screening. AIMS To assess the impact of phone-only visits on HCC screening rates in patients with cirrhosis. METHODS Utilizing ICD-10 codes, 2 cohorts of patients with cirrhosis were identified. The pre-pandemic cohort had index visit between 1/1/2019 and 6/30/2019 (n = 290). The pandemic cohort (n = 112) was evaluated between 4/7/2020 and 6/7/2020. Each cohort was followed for 6 months from their index visit to determine HCC screening rate. Demographics and socioeconomic data from the American Community Survey database were compiled and compared between the cohorts. RESULTS HCC screening rates in the pre-pandemic and pandemic cohorts were 72.4% and 69.6%, respectively, p = 0.67. No differences in HCC screening rates were observed between the two cohorts when stratified by demographic and socioeconomic factors. CONCLUSIONS Use of phone-only visits was associated with adherence to HCC screening similar to that seen with in-person visits. The lack of influence on screening rates by racial/socioeconomic factors suggest telephone-only visits do not exacerbate healthcare disparities. In times of public health of crisis, telephone-only visits may provide the necessary access to hepatology care to ensure HCC screening regimens remain in-place for at-risk patients.

Characteristics of Adult Primary Care Patients Who Use the Patient Portal: A Cross-Sectional Analysis. Appl Clin Inform 2022; 13:1053-1062. [PMID: 36167336 PMCID: PMC9629981 DOI: 10.1055/a-1951-3153] [Citation(s) in RCA: 6] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2022] [Accepted: 09/23/2022] [Indexed: 11/02/2022] Open
Abstract
BACKGROUND The patient portal allows patients to engage with their health care team beyond the clinical encounter. While portals can improve patient outcomes, there may be disparities in which patients access the portal by sociodemographic factors. Understanding the characteristics of patients who use the portal could help design future interventions to expand portal adoption. OBJECTIVES This study aimed to (1) examine the socioeconomic factors, comorbid conditions, and health care utilization among patients of a large academic primary care network who are users and non-users of the patient portal; and (2) describe the portal functions most frequently utilized. METHODS We included all adult patients at Atrium Health Wake Forest Baptist who had at least two primary care visits between 2018 and 2019. Patients' demographics, comorbidities, health care utilization, and portal function usage were extracted from the electronic health record and merged with census data (income, education, and unemployment) from the American Community Survey. A myWakeHealth portal user was defined as a patient who used a bidirectional portal function at least once during the study period. We used multivariable logistic regression to determine which patient characteristics were independently associated with being a portal user. RESULTS Of the 178,720 patients who met inclusion criteria, 32% (N = 57,122) were users of myWakeHealth. Compared to non-users, users were more likely to be 18 to 64 years of age, female, non-Hispanic White, married, commercially insured, have higher disease burden, and have lower health care utilization. Patients residing in areas with the highest educational attainment had 51% higher odds of being a portal user than the lowest (p <0.001). Among portal users, the most commonly used function was messaging clinic providers. CONCLUSION We found that patient demographics and area socioeconomic factors were associated with patient portal adoption. These findings suggest that efforts to improve portal adoption should be targeted at vulnerable patients.

Abstract
27 Background: In the US, two million people are referred to urologists for the evaluation of microscopic hematuria (MH). MH guidelines were revised in 2020 by the American Urological Association, recommending that only patients at high risk for malignancy based on age, smoking history, or urinalysis receive computed tomography (CT) imaging. We found in previous studies that providers continued to use CT for patients with low-to-intermediate risk, representing low-value care. To understand reasons for continued CT use for patients with low-to-intermediate risk MH, we assessed determinants of low-value care in a concurrent mixed-method study. Methods: We stratified patients with a urology consultation within 180 days of a urinalysis documented in one academic medical center’s electronic health record between 1/1/15 and 7/1/21 into high-, intermediate-, and low-risk categories and validated risk designation in a chart review of a 5% subsample. We defined low-value care as CT for patients with low-to-intermediate-risk MH. To assess determinants of low-value MH care, we conducted semi-structured interviews with primary, urology, and gynecology providers (n = 7) identified through our professional networks. Results: Six hundred nineteen patients were referred to urology for MH. 58.6% were high-risk, 33.6% intermediate-risk, 4.4% low-risk, and 3.4% were undefined. 15.9% of intermediate-risk (n = 33) and 11.1% of low-risk (n = 3) patients received CT. Of the 14 patients referred to urology post-guideline change, none with low-to-intermediate-risk received CT. Interviews demonstrated substantial variation in approaches to MH evaluation. Urologists were largely aware of the revised guideline but noted inappropriate evaluation before referral, unnecessary referrals, and inefficiency in evaluation following referral. Lacking accessible data for risk stratification, other providers’ approaches were varied but driven by a common goal of ruling out renal malignancy, based on medical school training and institutional norms. Conclusions: Low-value care was limited but persistent and may be driven by a lack of resources to support risk-stratified MH evaluation, including accessible risk stratification data and clear guidelines for appropriate evaluation. This is consistent with a lack of practical guidance for implementing MH evaluation guidelines. In future studies, we will develop strategies to facilitate risk-stratified MH evaluation in practice.

Abstract
226 Background: Cancer survivors may be more likely to receive preventive care services when they see both oncologists and PCPs; however, some oncology visits may not be necessary, straining limited subspecialty resources. In this study, we quantified outpatient primary and oncology care utilization in the years surrounding cancer diagnosis. We further characterized the proportion of survivors with oncology visits in the absence of ongoing antineoplastic use, as we hypothesized these survivors might be appropriate for need- and risk-stratified survivorship care, a model successful outside the US. Methods: We conducted a retrospective review of the electronic health records of survivors in an academic health center diagnosed with breast, colorectal, or uterine cancer between 1/1/14 and 9/1/19. We excluded survivors who died during the study period, had a PCP outside of our health system, or had recurrent cancers. Descriptive statistics described survivors’ provider visits up to 4 years before and 8 years after diagnosis with their most recent cancer. We then stratified our results by current antineoplastic prescription. Results: Our sample included 1,929 survivors (75.0% white, 20.1% Black, 5.0% other; 86.2% female; cancer type: 59.4% breast, 26.7% colorectal, 13.8% uterine). In the first-year post-diagnosis, 94.6% of survivors had an oncology provider visit; the figure declined to 55.8% by year 8. The percentage of survivors with PCP visits increased from 41% 3-4 years pre-diagnosis to 66% in year 1 and remained at > 50% 8 years post-diagnosis. More than 50% of survivors saw both PCPs and oncologists through 5 years post-diagnosis. Survivors were slightly more likely to have an oncology visit if they were on antineoplastics; 5+ years after diagnosis, >50% of survivors not on antineoplastics had oncology visits. Conclusions: A slight majority of 5+ year survivors, regardless of antineoplastic use, continue to have oncology visits and may be candidates for discontinuing oncology care. Work is needed to develop and test interventions to facilitate need- and risk-stratified survivorship care focused on transitioning longer-term survivors not on antineoplastics to PCPs.

Distinctive Clinical Correlates of Small Intestinal Bacterial Overgrowth with Methanogens. Clin Gastroenterol Hepatol 2022; 20:1598-1605.e2. [PMID: 34597730 DOI: 10.1016/j.cgh.2021.09.035] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2021] [Revised: 09/13/2021] [Accepted: 09/22/2021] [Indexed: 02/06/2023]
Abstract
BACKGROUND AND AIMS Most patients with small intestinal bacterial overgrowth (SIBO) produce hydrogen by fermentation of dietary carbohydrates; however, ∼30% of patients with SIBO are colonized with Archaea, anaerobic organisms that produce methane. SIBO is associated with a plethora of symptoms and conditions, but their diagnostic significance is unclear. We aimed to determine if specific symptoms and conditions are associated with methanogenic SIBO. METHODS This study received institutional review board approval (IRB00059873). In this retrospective cross-sectional study, we queried a database of glucose breath tests conducted for suspected SIBO at our tertiary care medical center, which included data on the presence or absence of gastrointestinal symptoms and conditions often associated with SIBO. All patients had undergone a standardized breath testing protocol. RESULTS In a cohort of 1461 patients, 33.1% were SIBO positive; of these, 49.8% produced only hydrogen, 38.8% produced only methane, and 11.4% produced both gases. The following factors distinguished patients with hydrogen-producing SIBO, but not methanogenic SIBO, from SIBO-negative patients: vitamin B12 deficiency (odds ratio, 1.44; confidence interval [CI], 1.01-2.06; P = .046), Roux-en-Y gastric bypass (odds ratio, 2.14; CI, 1.09-4.18; P = .027), cholecystectomy (odds ratio, 1.42; CI, 1.06-1.91; P = .020), and diabetes (odds ratio, 1.59; CI, 1.13-2.24; P = .008). The absence of vitamin B12 deficiency was the sole discriminating factor between methanogenic and hydrogenic SIBO (odds ratio, 0.57; CI, 0.34-0.97; P = .038). CONCLUSIONS Patients with SIBO caused by methane-producing Archaea display a different spectrum of associated symptoms and clinical conditions compared with patients with SIBO caused by hydrogen-producing bacteria, particularly a lower incidence of vitamin B12 deficiency.

Abstract
BACKGROUND Hybrid closed-loop (HCL) insulin pump therapy (Medtronic 670G) is an emerging technology that is growing in use worldwide. Initial clinical trials demonstrated the effectiveness of HCL in reducing hypoglycemia and improving glucose control; however, these subjects were intensely monitored and supervised. There has been concern regarding the ability of patients to remain in auto mode. We aimed to assess HCL when used in a typical outpatient endocrine clinic. METHODS We initially analyzed data from 80 individuals with type 1 diabetes managed in an endocrine clinic by a single certified diabetes educator (CDE). We then included our other providers and had 230 subjects by the end of the study. Patients were either transitioned from traditional insulin pump or multiple daily insulin injection therapy (MDI) to HCL. Patients initiated to HCL pump therapy from July 2017 through February 2020 were studied. Endpoints of change in time in hypoglycemic/hyperglycemic range and time in target range were analyzed. The primary outcome was a change in percent time in the target range during manual mode compared with auto mode. RESULTS There was an 18.2% increase in average time in target range when comparing manual mode to auto mode (59.3% vs 70.1%, P < .0001). Average time in hyperglycemic range was significantly reduced by 26.7% (39.0% vs 28.6%, P < .0001) but without increasing average time in hypoglycemic range (1.7% vs 1.3%, P = 0.95). CONCLUSIONS HCL was effective in reducing hyperglycemia and increasing time in the target range but did not increase hypoglycemia. These data suggest HCL will improve the metrics of glucose control.

Abstract
OBJECTIVE We designed and implemented an application programming interface (API)-based electronic health record (EHR)-integrated rounding list and evaluated acceptability, clinician satisfaction, information accuracy, and efficiency related to the application. METHODS We developed and integrated an application, employing iterative design techniques with user feedback. EHR and application user action logs, as well as hospital safety reports, were evaluated. Rounding preparation characteristics were obtained through surveys before and after application integration. To evaluate usability, inpatient providers, including residents, fellows, and attendings were surveyed 2 weeks prior to and 6 months after enterprise-wide EHR application integration. Our primary outcome was provider time savings measured by user action logs; secondary outcomes include provider satisfaction. RESULTS The application was widely adopted by inpatient providers, with more than 69% of all inpatients queried by the application within 6 months of deployment. Application utilization was sustained throughout the study period with 79% (interquartile range [IQR]: 76, 82) of enterprise-wide unique patients accessed per weekday. EHR action logs showed application users spent -3.24 minutes per day (95% confidence interval [CI]: -6.8, 0.33), p = 0.07 within the EHR compared with nonusers. Median self-reported chart review time for attendings decreased from 30 minutes (IQR: 15, 60) to 20 minutes (IQR: 10, 45) after application integration (p = 0.04). Self-reported sign-out preparation time decreased by a median of 5 minutes (p < 0.01), and providers were better prepared for hand-offs (p = 0.02). There were no increased safety reports during the study period. CONCLUSION This study demonstrates successful integration of a rounding application within a commercial EHR using APIs. We demonstrate increasing both provider-reported satisfaction and time savings. Rounding lists provided more accurate and timely information for rounds. Application usage was sustained across multiple specialties at 42 months. Other application designers should consider data density, optimization of provider workflows, and using real-time data transfer using novel tools when designing an application.

Abstract
The objective of this study was to determine the feasibility of a computerized clinical decision support (cCDS) tool to facilitate referral to adult healthcare services for children with special healthcare needs. A transition-specific cCDS was implemented as part of standard care in a general pediatrics clinic at a tertiary care academic medical center. The cCDS alerts providers to patients 17-26 years old with 1 or more of 15 diagnoses that may be candidates for referral to an internal medicine adult transition clinic (ATC). Provider responses to the cCDS and referral outcomes (e.g. scheduled and completed visits) were retrospectively analyzed using descriptive statistics. One hundred and fifty-two patients were seen during the 20-month observation period. Providers referred 87 patients to the ATC using cCDS and 77% of patients ≥18 years old scheduled a visit in the ATC. Transition-specific cCDS tools are feasible options to facilitate adult care transitions for children with special healthcare needs.

Abstract
BACKGROUND In patients with critical medical illness, data regarding new-onset atrial fibrillation (NOAF) is relatively sparse. This study examines the incidence, associated risk factors, and associated outcomes of NOAF in patients in the medical intensive care unit (MICU). METHODS This single-center retrospective observational cohort study included 2234 patients with MICU stays in 2018. An automated extraction process using ICD-10 codes, validated by a 196-patient manual chart review, was used for data collection. Demographics, medications, and risk factors were collected. Multiple risk scores were calculated for each patient, and AF recurrence was also manually extracted. Length of stay, mortality, and new stroke were primary recorded outcomes. RESULTS Two hundred and forty one patients of the 2234 patient cohort (11.4%) developed NOAF during their MICU stay. NOAF was associated with greater length of stay in the MICU (5.84 vs. 3.52 days, p < .001) and in the hospital (15.7 vs. 10.9 days, p < .001). Patients with NOAF had greater odds of hospital mortality (odds ratio (OR) = 1.92, 95% confidence interval (CI) 1.34-2.71, p < .001) and 1-year mortality (OR = 1.37, 95% CI 1.02-1.82, p = .03). CHARGE-AF scores performed best in predicting NOAF (area under the curve (AUC) 0.691, p < .001). CONCLUSIONS The incidence of NOAF in this MICU cohort was 11.4%, and NOAF was associated with a significant increase in hospital LOS and mortality. Furthermore, the CHARGE-AF score performed best in predicting NOAF.

Abstract
e14034 Background: Primary brain malignancy is distinct from other oncologic diagnoses in its presentation and course. Recent treatment advances have modestly improved survival; yet, prognoses for afflicted patients remain grim, which often leads to non-oncology providers questioning the pertinence of aggressive critical care in this population. By relating patient and disease factors with mortality rates in malignant brain tumor (MBT) patients admitted for critical care, we seek to identify valuable prognostic factors and clarify the expected outcomes following intensive care unit (ICU) admission among these patients. Methods: A single-institution retrospective review was performed of 80 primary MBT patients admitted to neuro- or medical ICUs over a five-year period. The Electronic Health Record (EHR) was queried to identify MBT patients who had been admitted to the ICU. Patients undergoing planned surgical resection or with post-operative complications were excluded, as were patients with brain metastases. A matched control group of 80 solid tumor (ST) patients (excluding brain tumors) was included for comparison. Similar aged matched controls were randomly identified via EHR over the same time period to include non-brain, ST patients admitted to the ICU. Demographic, oncologic, and admission data were related to outcomes, which included complication rates (ICU mortality, six-month mortality) and change in Karnofsky Performance Status (KPS) score. Results: The average age was 55.9 (20-83) and 62.8 (27-89) years in the MBT and ST group, respectively (p = 0.10). ICU mortality was 15% and 21% (p = 0.411) and six-month mortality was 46% and 65% (p = 0.10) in the MBT and control groups, respectively. The most common reasons for ICU admission were seizures (36%) and septic shock (21%) among MBT patients, compared to hypoxic respiratory failure (43%) and septic shock (30%) among ST patients. The MBT group’s KPS score decreased by 23.6 ± 26.82 during their ICU admission, while the control group KPS decreased by 27.0 ± 28.3 (p = 0.87). Average length of ICU stay was 3.82 ± 4.4 days in the MBT group, compared to 2.95 ± 1.83 days in the control ST group (p = 0.29). Average length of hospital stay was 9.07 ± 9.0 days in the MBT group and 8.67 ± 7.76 days in the ST group (p = 0.92). Conclusions: No significant difference was observed in ICU or 6-month mortality when comparing primary MBT and ST patients. Change in KPS score across ICU admissions was similar among the two groups. Our data indicate that despite their guarded prognosis, MBT patients fare no worse than those with other solid tumor types at our institution in the critical care setting. These similarities in mortality and functional scores justify medical ICU admission in patients with primary brain malignancy, and should inform intensivist and oncologist admission patterns.

Abstract
OBJECTIVES Optimizing care for patients with advanced kidney disease requires close collaboration between primary care physicians (PCPs) and nephrologists. Factors associated with PCP referral to nephrology were assessed in patients with estimated glomerular filtration rates (eGFRs) less than 30 mL/min/1.73 m2. STUDY DESIGN Electronic health record review at an integrated health care network. METHODS Factors associated with referral status were identified using Fisher's exact tests, t tests, and multivariable logistic regression. RESULTS Of 133,913 patients regularly seeing PCPs between October 2017 and September 2019, 1119 had a final eGFR less than 30 mL/min/1.73 m2 and were not on renal replacement therapy. Care was provided by 185 PCPs (61 practices). Analyses were restricted to the 97.1% (n = 1087) of patients who were African American or European American. Of these, 54.6% had not been referred to nephrology. Nonreferred patients had higher numbers of PCP visits (P = .004). In contrast, referred patients were younger, were more often African American, and had PCPs at the academic medical center (all P < .0001). Referred patients had more complex medical histories with higher Charlson Comorbidity Index scores, more hospitalizations, and greater numbers of inpatient days (all P < .0001). Analyses restricted to patients with serum creatinine concentration of at least 2 mg/dL yielded similar results. Age, number of hospitalizations, ancestry, academic physician, diabetic end-organ damage, peripheral vascular disease, and tumor status were independent predictors of nephrology referral. CONCLUSIONS Impediments to appropriately timed nephrology referrals persist in patients with high likelihoods of progression to end-stage kidney disease. Improved access to nephrology care should be rapidly addressed to meet targets in the 2019 Executive Order on Advancing American Kidney Health.

Abstract
Mobile health tools may overcome barriers to social needs screening; however, there are limited data on the feasibility of using these tools in clinical settings. The objective was to determine the feasibility of using a mobile health system to screen for patients' social needs. In one large primary care clinic, the authors tested a tablet-based system that screens patients for social needs, transmits results to the electronic health record, and alerts providers. All adult patients presenting for a nonurgent visit were eligible. The authors evaluated the feasibility of the system and conducted follow-up surveys to determine acceptability and if patients accessed resources through the process. All providers were surveyed. Of the 252 patients approached, 219 (86.9%) completed the screen. Forty-three (19.6%) required assistance with the tablet, and 150 (68.5%) screened positive for at least 1 unmet need (food, housing, or transportation). Of the 150, 103 (68.7%) completed a follow-up survey. The majority agreed that people would learn to use the tablet quickly. Forty-eight patients (46.6%) reported contacting at least 1 community organization through the process. Of the 27 providers, 23 (85.2%) completed a survey and >70% agreed the system would result in patients having better access to resources. It was feasible to use a tablet-based system to screen for social needs. Clinics considering using mobile tools will need to determine how to screen patients who may need assistance with the tool and how to connect patients to resources through the system based on the burden of unmet needs.

Abstract
BACKGROUND Osteoarthritis (OA) of the knee is the most prevalent joint disorder. Previous studies suggest that bromelain, a pineapple extract, may be a safer alternative/adjunctive treatment for knee OA than current conventional treatment. AIM To assess the efficacy of bromelain in treating OA of the knee. DESIGN Randomized, double-blind placebo-controlled trial. METHODS Subjects (n = 47) with a confirmed diagnosis of moderate to severe knee OA were randomized to 12 weeks of bromelain 800 mg/day or placebo, with a 4-week follow-up. Knee (pain, stiffness and function) and quality-of-life symptoms were reported monthly in the WOMAC and SF36 questionnaires, respectively. Adverse events were also recorded. The primary outcome measure was the change in total WOMAC score from baseline to the end of treatment at week 12. Longitudinal models were used to evaluate outcome. RESULTS Thirty-one patients completed the trial (14 bromelain, 17 placebo). No statistically significant differences were observed between groups for the primary outcome (coefficient 11.16, p = 0.27, 95%CI -8.86 to 31.18), nor the WOMAC subscales or SF36. Both treatment groups showed clinically relevant improvement in the WOMAC disability subscale only. Adverse events were generally mild in nature. DISCUSSION This study suggests that bromelain is not efficacious as an adjunctive treatment of moderate to severe OA, but its limitations support the need for a follow-up study.

Abstract
There is preliminary clinical evidence to support the contention that the anti-inflammatory and analgesic properties of bromelain help to reduce symptoms of osteo- and rheumatoid arthritis. However, there have been no controlled studies of its effects on joint health in healthy subjects who lack such diagnosis. The current study investigated the effects of bromelain on mild acute knee pain of less than 3 months duration in otherwise healthy adults. The study was an open, dose-ranging postal study in volunteers who had been recruited through newspaper and magazine articles. Two validated questionnaires (WOMAC knee health Index and the Psychological Well-Being Index) were completed at baseline and after one month's intervention with bromelain, randomly allocated to volunteers as either 200 mg or 400 mg per day. Seventy seven subjects completed the study. In both treatment groups, all WOMAC symptom dimension scores were significantly reduced compared with baseline, with reductions in the final battery (total symptom score) of 41 and 59% (P = 0.0001 and <0.0001) in the low and high dose groups respectively. In addition, improvements in total symptom score (P = 0.036) and the stiffness (P = 0.026) and physical function (P = 0.021) dimensions were significantly greater in the high-dose (400 mg per day) compared with the low-dose group. Compared to baseline, overall psychological well-being was significantly improved in both groups after treatment (P = 0.015 and P = 0.0003 in the low and high dose groups respectively), and again, a significant dose-response relationship was observed. We conclude that bromelain may be effective in ameliorating physical symptoms and improving general well-being in otherwise healthy adults suffering from mild knee pain in a dose-dependant manner. Double blind, placebo-controlled studies are now warranted to confirm these results.

Metabolism of lactose-[13C]ureide and lactose-[15N,15N]ureide in normal adults consuming a diet marginally adequate in protein. Clin Sci (Lond) 1999; 97:547-55.

Abstract
Oral lactose-ureide is resistant to human digestive enzymes, but is fermented by the colonic microflora. Nine normal adults consuming a diet which provided 36 g of protein/day were given oral doses of lactose-[(13)C]ureide and lactose-[(15)N,(15)N]ureide. The appearance on breath of (13)CO(2) derived from lactose-[(13)C]ureide was followed for 48 h. The fate of (15)N derived from lactose-[(15)N, (15)N]ureide was determined by measuring the recovery of (15)N in stools and urine in various forms. About 80% of the label given as lactose-[(13)C]ureide was recovered on the breath, and about 80% of label given as lactose-[(15)N,(15)N]ureide was not recovered in stool, indicating that 80% of the dose was completely fermented. At least 5% of the labelled urea was absorbed and excreted as the intact molecule. Of the (15)N derived from lactose-[(15)N, (15)N]ureide and available for further metabolic interaction, 67% was retained and 33% was excreted in urine. The time taken for [(15)N,(15)N]urea to appear in urine was similar for all subjects, but the appearance of either (13)CO(2) on the breath or [(15)N, (14)N]urea in urine varied. It is concluded that the hydrolysis of the sugar-urea bond may reflect oro-caecal transit time, but that other factors related to colonic bacterial metabolism determine the duration and extent of hydrolysis of urea by urease enzymes. Lactose-ureide can be used to probe the metabolic activity of the colonic microflora in normal individuals.

Differential regulation of DNA synthesis by nitric oxide and hydroxyurea in vascular smooth muscle cells. THE AMERICAN JOURNAL OF PHYSIOLOGY 1999; 277:H1799-807.

Abstract
We investigated the influence of nitrovasodilators on DNA synthesis in cultured human aortic smooth muscle cells and explored the hypothesis that nitric oxide (NO) is directly involved in mediating the inhibitory effects of hydroxyurea on DNA synthesis. Both NO and hydroxyurea inhibited ongoing DNA synthesis and S phase progression in our cells. Exogenous deoxynucleosides partially reversed this inhibition, suggesting that ribonucleotide reductase is a primary target for both NO and hydroxyurea. Nitrovasodilators inhibited DNA synthesis by releasing NO, as detected by chemiluminescence and as shown by the reversal of DNA synthesis inhibition by NO scavengers. This inhibition appears to occur via a cGMP-independent mechanism. In contrast, hydroxyurea did not produce a detectable NO signal, and NO scavengers had no influence on its inhibition of DNA synthesis, suggesting that NO does not mediate the inhibitory action of hydroxyurea in our system. Furthermore, the action of nitrovasodilators and hydroxyurea on DNA synthesis differed according to redox sensitivity. The redox agents N-acetyl-L-cysteine and ascorbate reversed NO inhibition of DNA synthesis and had no effect on DNA synthesis inhibition caused by hydroxyurea.

Urinary excretion of 5-L-oxoproline (pyroglutamic acid) is increased in normal adults consuming vegetarian or low protein diets. J Nutr 1996; 126:2813-22.

Abstract
A method for measuring 5-L-oxoproline in urine, which involves isolation by short-column chromatography, acid hydrolysis to glutamic acid and enzymic assay of glutamic acid, was used to measure the rate of excretion in normal adults, aged 20 to 45 y. There was no difference in the daily excretion between omnivorous males (217 micromol/d) and females (195 micromol/d). In vegetarian males, urinary 5-L-oxoproline (404 micromol/d) was significantly greater than in vegetarian females (267 micromol/d, P = 0.013). Compared with omnivorous males or females, excretion of 5-L-oxoproline was significantly greater in vegetarian males (P < 0.0001) and females (P= 0.005). When normal adults consumed a diet in which the protein content was controlled at either 4.0 or 6.2 g N/d for 5 d, there was a significant increase in urinary 5-L-oxoproline on d 5, compared with either d 1 or 4. There was a significant inverse linear relationship between the increased urinary 5-L-oxoproline on the fifth dietary day and the nitrogen content of the diet. On the basis of this relationship, when the urinary excretion of 5-L-oxoproline (320 micromol/d) for vegetarians was predicted from an estimate of their dietary intake of nitrogen, the estimate was, on average, close to the measured value (345 micromol/d). As a matter of course, vegetarians excrete more 5-L-oxoproline in urine than do omnivores, and we speculated that this difference might be accounted for by differences in dietary nitrogen and the endogenous capacity for de novo synthesis of glycine.

Abstract
The purpose of the present study was to analyze the manner in which series and parallel arrangements of respiratory muscles, contracting together, augment the forces and displacements applied to external elastic loads over those produced by a single muscle contracting alone. We first developed a series of mathematical expressions to describe the behavior of various arrangements of muscles contracting against elastic loads. We then compared the predictions of these equations with the results from experiments in which the forces and displacements produced by simple arrangements of muscles were measured. Both theoretical and experimental results indicate that, against high elastic loads, parallel arrangements of muscle strips produce greater forces and greater displacements than do single muscles; parallel arrangements do not, however, significantly increase the displacement or force applied to low elastic loads. Conversely, series arrangements result in greater forces and greater displacement of low loads, but are no better than single muscles when contracting against high loads. Against moderate loads parallel and series arrangements of muscles appear to be equivalent in generating forces and displacements during contraction. This analysis suggests that a major determinant of the effects of contraction of various networks of inspiratory muscles is the magnitude and character of the respiratory impedance against which these muscles must work. The primary difference between series and parallel arrangements of muscles is that muscles arranged in series are most effective against low elastic loads and muscles in parallel act most effectively against high loads.

Abstract
Recent studies examining the effects of hypoxia on diaphragm function have reached conflicting conclusions, with some reports suggesting an adverse effect of even mild hypoxemia while others indicate that the diaphragm may be extremely resistant to hypoxic stress. Diaphragm tension was not, however, directly measured nor was diaphragm length controlled in these previous reports, and it seems possible that methodologic limitations may have been responsible for these discrepant results. The purpose of the present study was to examine the effects of graded, steady-state hypoxia on diaphragm blood flow, oxygen extraction, oxygen consumption, and contractility using an in situ canine diaphragm strip preparation that permitted direct and continuous measurement of diaphragm length, tension, and blood flow. Measurements were made with the diaphragm at rest, during normoxia (PaO2, 90 to 160 mm Hg), mild hypoxia (PaO2, 45 to 60 mm Hg), and severe hypoxia (PaO2, 25 to 35 mm Hg); measurements were made with the diaphragm at rest, during rhythmic contractions at a tension time index (TTI) of 0.05, and with contractions at a TTI of 0.15. Decreases in arterial oxygenation resulted in progressive increases in blood flow and in the fractional extraction of oxygen in both resting and contracting diaphragm strips. At all levels of activity tested, blood flow and fractional extraction increased sufficiently to keep diaphragm oxygen consumption constant despite reductions in arterial oxygen content. Diaphragm contractility, as assessed from the tension generated in response to a range of electrical stimuli (1 to 80 Hz), was unaffected by hypoxia for trials performed with the diaphragm at rest and contracting at a TTI of 0.05.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
Two series of uncharged conjugated bile salt derivatives, N-conjugates of ethanolamine and 3-amino-1,2-propanediol were studied for interaction with the ileal bile salt transport system. Evidence for interaction is threefold. 1) In everted gut sac experiments more material was removed from the mucosal compartment when ileal sacs were used. 2) These derivatives inhibited the in vitro transport of taurocholate. 3) In vivo intestinal perfusion demonstrated greater absorption from ileum than from jejunum. Number three demonstrates that such interactions are followed by transmucosal movement. Their uphill transport was less than taurocholate transport. The Na(+) requirement for cholyl-3-amino-1,2-propanediol interaction with the system was greater than for taurocholate. This observation is similar to that previously observed with taurodehydrocholate, which had a greater Na(+) requirement for transport than taurocholate. Therefore removal of the anionic charge, as well as distortion of steroid shape, increases the Na(+) requirement for substrate interaction with the transport system. These observations support our hypothesis that this interaction involves two recognition components; one includes the steroid moiety, the other a coulombic interaction between the anionic bile salt and a cationic membrane site. Additionally the membrane would have an anionic group to accomodate the Na(+). Both factors (steroidal and coulombic) operate for optimal substrate attachment. Simultaneously the system's affinity for Na(+) increases and active transport then proceeds.
