Disparities Persist Among Hispanic Patients: Completing Evaluation, Waitlisting, and Receiving a Kidney Transplant.

Background: Hispanic patients receive disproportionately fewer kidney transplants (KT) than non-Hispanic White (NHW) patients. In this observational study, we evaluated disparities in completing evaluation steps to KT among Hispanic patients. Methods: Using medical records of Hispanic and NHW patients initiating evaluation at 4 transplant centers from January 2011 to March 2020, we performed sequential Cox models to compare Hispanic versus NHW patients reaching each step of the evaluation process until receiving a KT. Results: Among all 5197 patients (Hispanic n = 2473; NHW n = 2724) initiating evaluation, Hispanic patients had 8% lower risk to be approved by the kidney pancreas (KP) committee than NHW patients (adjusted hazard ratio [aHR], 0.92; 95% confidence intervals (CI), 0.86-0.98; P = 0.015). Among 3492 patients approved by the KP committee, Hispanic patients had 13% lower risk to be waitlisted than NHW patients (aHR, 0.87; 95% CI, 0.81-0.94; P = 0.004). Among 3382 patients who were waitlisted, Hispanic patients had 11% lower risk than NHW patients to receive KT (aHR, 0.89; 95% CI, 0.81-0.97; P = 0.011). Among all patients initiating evaluation, Hispanic patients had a 16% lower risk than NHW patients to reach KT (aHR, 0.84; 95% CI, 0.76-0.92; P = 0.0002). Conclusions: Our study found that disproportionately fewer Hispanic patients were approved by the KP committee, were waitlisted, and received a KT, particularly a living donor kidney transplant, than NHW patients. Closer oversight of the evaluation process may help patients overcome challenges in access to KT.

Clinical and economic impact of medication reconciliation by designated ward pharmacists in a hospitalist-managed acute medical unit.

BACKGROUND: Minimizing unintended medication errors after admission is a common goal for clinical pharmacists and hospitalists. OBJECTIVE: We assessed the clinical and economic impact of a medication reconciliation service in a model of designated ward pharmacists working in a hospitalist-managed acute medical unit as part of a multidisciplinary team. METHODS: In this retrospective observational study, we compared pharmacist intervention records before and after the implementation of a medication reconciliation service by designated pharmacists. The frequency and type of intervention were assessed and their clinical impact was estimated according to the length of hospital stay and 30-day readmission rate. A cost analysis was performed using the average hourly salary of a pharmacist, cost of interventions (time spent on interventions), and cost avoidance (avoided costs generated by interventions). RESULTS: After the implementation of the medication reconciliation service, the frequency of pharmacist interventions increased from 3.9% to 22.1% (p < 0.001). Intervention types were also more diverse than those before the implementation. The most common interventions included identifying medication discrepancies between pre-admission and hospitalization (22.7%) and potentially inappropriate medication use in the elderly (13.1%). The median length of hospital stay decreased from 9.6 to 8.9 days (p = 0.024); the 30-day readmission rate declined significantly from 7.8% to 4.8% (p = 0.046). Over two-thirds of interventions accepted by hospitalists were considered clinically significant or greater in severity. The cost difference between avoided cost and cost of interventions was 9838.58 USD in total or 1967.72 USD per month. CONCLUSIONS: The implementation of a designated pharmacist-led medication reconciliation service had a positive clinical and economic impact in our hospitalist unit.

Effectiveness of a culturally competent care intervention in reducing disparities in Hispanic live donor kidney transplantation: A hybrid trial.

Hispanic patients receive disproportionately fewer living donor kidney transplants (LDKTs) than non-Hispanic Whites (NHWs). The Northwestern Medicine Hispanic Kidney Transplant Program (HKTP), designed to increase Hispanic LDKTs, was evaluated as a nonrandomized, implementation-effectiveness hybrid trial of patients initiating transplant evaluation at two intervention and two similar control sites. Using a mixed method, observational design, we evaluated the fidelity of the HKTP implementation at the two intervention sites. We tested the impact of the HKTP intervention by evaluating the likelihood of receiving LDKT comparing pre-intervention (January 2011-December 2016) and postintervention (January 2017-March 2020), across ethnicity and centers. The HKTP study included 2063 recipients. Intervention Site A exhibited greater implementation fidelity than intervention Site B. For Hispanic recipients at Site A, the likelihood of receiving LDKTs was significantly higher at postintervention compared with pre-intervention (odds ratio [OR] = 3.17 95% confidence interval [1.04, 9.63]), but not at the paired control Site C (OR = 1.02 [0.61, 1.71]). For Hispanic recipients at Site B, the likelihood of receiving an LDKT did not differ between pre- and postintervention (OR = 0.88 [0.40, 1.94]). The LDKT rate was significantly lower for Hispanics at paired control Site D (OR = 0.45 [0.28, 0.90]). The intervention significantly improved LDKT rates for Hispanic patients at the intervention site that implemented the intervention with greater fidelity. Registration: ClinicalTrials.gov registered (retrospectively) on September 7, 2017 (NCT03276390).

Redesigning systems to improve teamwork and quality for hospitalized patients (RESET): study protocol evaluating the effect of mentored implementation to redesign clinical microsystems.

BACKGROUND: A number of challenges impede our ability to consistently provide high quality care to patients hospitalized with medical conditions. Teams are large, team membership continually evolves, and physicians are often spread across multiple units and floors. Moreover, patients and family members are generally poorly informed and lack opportunities to partner in decision making. Prior studies have tested interventions to redesign aspects of the care delivery system for hospitalized medical patients, but the majority have evaluated the effect of a single intervention. We believe these interventions represent complementary and mutually reinforcing components of a redesigned clinical microsystem. Our specific objective for this study is to implement a set of evidence-based complementary interventions across a range of clinical microsystems, identify factors and strategies associated with successful implementation, and evaluate the impact on quality. METHODS: The RESET project uses the Advanced and Integrated MicroSystems (AIMS) interventions. The AIMS interventions consist of 1) Unit-based Physician Teams, 2) Unit Nurse-Physician Co-leadership, 3) Enhanced Interprofessional Rounds, 4) Unit-level Performance Reports, and 5) Patient Engagement Activities. Four hospital sites were chosen to receive guidance and resources as they implement the AIMS interventions. Each study site has assembled a local leadership team, consisting of a physician and nurse, and receives mentorship from a physician and nurse with experience in leading similar interventions. Primary outcomes include teamwork climate, assessed using the Safety Attitudes Questionnaire, and adverse events using the Medicare Patient Safety Monitoring System (MPSMS). RESET uses a parallel group study design and two group pretest-posttest analyses for primary outcomes. We use a multi-method approach to collect and triangulate qualitative data collected during 3 visits to study sites. We will use cross-case comparisons to consider how site-specific contextual factors interact with the variation in the intensity and fidelity of implementation to affect teamwork and patient outcomes. DISCUSSION: The RESET study provides mentorship and resources to assist hospitals as they implement complementary and mutually reinforcing components to redesign the clinical microsystems caring for medical patients. Our findings will be of interest and directly applicable to all hospitals providing care to patients with medical conditions. TRIAL REGISTRATION: NCT03745677 .

A National Survey of Transplant Surgeons and Nephrologists on Implementing Apolipoprotein L1 (APOL1) Genetic Testing Into Clinical Practice.

INTRODUCTION: There is debate over whether Apolipoprotein L1 (APOL1) gene risk variants contribute to African American (AA) live donors' (LD) increased risk of kidney failure. Little is known about factors influencing physicians' integration of APOL1 genetic testing of AA LDs into donor evaluation. DESIGN: We conducted a cross-sectional survey, informed by Roger's Diffusion of Innovations theory, among nephrology and surgeon members of the American Society of Nephrology, American Society of Transplantation, and American Society of Transplant Surgeons about their practices of and attitudes about APOL1 genetic testing of AA potential LDs. Descriptive statistics and bivariate analyses were performed. RESULTS: Of 383 completed surveys, most physicians believed that APOL1 testing can help AA LDs make more informed donation decisions (87%), and the addition of APOL1 testing offers better clinical information about AA LD's eligibility for donation than existing evaluation approaches (74%). Among respondents who evaluate LDs (n = 345), 63% would definitely or probably begin or continue using APOL1 testing in the next year, however, few use APOL1 testing routinely (4%) or on a case-by-case basis (14%). Most did not know the right clinical scenario to order APOL1 testing (59%), but would use educational materials to counsel AA LDs about APOL1 testing (97%). DISCUSSION: Although physicians were highly supportive of APOL1 genetic testing for AA LDs, few physicians use APOL1 testing. As more physicians intend to use APOL1 testing, an ethical framework and clinical decision support are needed presently to assist clinicians in clarifying the proper indication of APOL1 genetic testing.

A complex culturally targeted intervention to reduce Hispanic disparities in living kidney donor transplantation: an effectiveness-implementation hybrid study protocol.

BACKGROUND: The shortage of organs for kidney transplantation for patients with end-stage renal disease (ESRD) is magnified in Hispanics/Latin Americans in the United States. Living donor kidney transplantation (LDKT) is the treatment of choice for ESRD. However, compared to their representation on the transplant waitlist, fewer Hispanics receive a LDKT than non-Hispanic whites. Barriers to LDKT for Hispanics include: lack of knowledge, cultural concerns, and language barriers. Few interventions have been designed to reduce LDKT disparities. This study aims to reduce Hispanic disparities in LDKT through a culturally targeted intervention. METHODS/DESIGN: Using a prospective effectiveness-implementation hybrid design involving pre-post intervention evaluation with matched controls, we will implement a complex culturally targeted intervention at two transplant centers in Dallas, TX and Phoenix, AZ. The goal of the study is to evaluate the effect of Northwestern Medicine's® Hispanic Kidney Transplant Program's (HKTP) key culturally targeted components (outreach, communication, education) on Hispanic LDKT rates over five years. The main hypothesis is that exposure to the HKTP will reduce disparities by increasing the ratio of Hispanic to non-Hispanic white LDKTs and the number of Hispanic LDKTs. We will also examine other process and outcome measures including: dialysis patient outreach, education session attendance, marketing efforts, Hispanic patients added to the waitlist, Hispanic potential donors per potential recipient, and satisfaction with culturally competent care. We will use mixed methods based on the Promoting Action on Research Implementation in Health Services (revised PARIHS) and the Consolidated Framework for Implementation Research (CFIR) frameworks to formatively evaluate the fidelity and innovative adaptations to HKTP's components at both study sites, to identify moderating factors that most affect implementation fidelity, and to identify adaptations that positively and negatively affect outcomes for patients. DISCUSSION: Our study will provide new knowledge about implementing culturally targeted interventions and their impact on reducing health disparities. Moreover, the study of a complex organizational-level intervention's implementation over five years is rare in implementation science; as such, this study is poised to contribute new knowledge to the factors influencing how organizational-level interventions are sustained over time.

Survival in systemic sclerosis-pulmonary arterial hypertension by serum autoantibody status in the Pulmonary Hypertension Assessment and Recognition of Outcomes in Scleroderma (PHAROS) Registry.

OBJECTIVE: To determine the association between serum autoantibodies and survival in patients with incident systemic sclerosis (SSc)-pulmonary arterial hypertension (PAH) enrolled in the Pulmonary Hypertension Assessment and Recognition of Outcomes in Scleroderma (PHAROS) Registry. METHODS: Patients with definite PAH diagnosed by right heart catheterization within 6 months of registry enrollment were studied. Serum autoantibodies were assayed at each participating institution's clinical laboratory. Mortality data were collected from electronic medical records and/or the Social Security Death Index. Kaplan-Meier survival estimates were reported for five autoantibody groups (anticentromere/AC, nucleolar ANA/NUC, anti-topoisomerase/Scl-70, overlapping or non-specific autoantibodies/other, and a combined group with similar survival consisting of RNA polymerase III, U1RNP, and autoantibody-negative patients). Cox proportional hazards models permitted examination of the association between autoantibody groups and overall survival, controlling for age, sex, race, and SSc disease duration. RESULTS: In all, 162 subjects had PAH, and serum autoantibody and survival information; 60 (37%) had AC, 39 (24%) NUC, 11 (7%) Scl-70, 28 (17%) had other, 9 (6%) RNA pol, 8 (5%) U1RNP autoantibodies, and 7 (4%) had negative antibodies; 32 (20%) subjects died over a median follow-up time of 2.1 years (range: 0.01-6.8); 1- and 3-year survival estimates were, respectively, 94% and 78% for AC, 94% and 72% for NUC, 89% and 63% for Scl-70, 92% and 79% for the other group, and 100% and 93% for the combined group. Unadjusted and adjusted hazard ratios revealed no statistically significant association between risk of death and autoantibodies. CONCLUSION: Anticentromere and NUC autoantibodies are prevalent in SSc-PAH patients. An association between serum autoantibodies and survival in patients with SSc-PAH was not identified in the PHAROS cohort.

Hispanic/Latino Disparities in Living Donor Kidney Transplantation: Role of a Culturally Competent Transplant Program.

UNLABELLED: Hispanic Americans face disparities in access to kidney transplantation, particularly living donor kidney transplantation (LDKT). This study compared characteristics of LDKT recipients before and after implementing the Hispanic Kidney Transplant Program (HKTP) at Northwestern Medicines (NM) and other centers. METHODS: The NM HKTP, initiated in December 2006, delivers culturally and linguistically competent and congruent care. Program-specific data were used to compare the mean ratios of Hispanic to non-Hispanic white LDKTs between pre-HKTP (2001-2006) and post-HKTP (2008-2013), and to compare the characteristics of NM's adult LDKT patients between pre-HKTP and post-HKTP. The same ratio was calculated for transplant centers in regions with a significant Hispanic population (≥25%) and performing in the top tertile of total LDKT volume in the pre-HKTP period. The number of Hispanic and non-Hispanic white patients added to the waiting list were compared between pre-HKTP (2001-2006) and post-HKTP (2008-2013) as a proxy for increased patient referrals and a pathway by which the HKTP may increase LDKTs. RESULTS: The ratio of Hispanic to non-Hispanic white LDKTs significantly increased by 70% after the implementation of NM's HKTP (pre-HKTP mean = 0.20, post-HKTP mean = 0.34; P= 0.001). None of the other transplant centers experienced a similar increase in their ratio of Hispanic to non-Hispanic white LDKTs. The NM waiting list additions grew by 91% among Hispanics, but grew only 4% for non-Hispanic whites. CONCLUSIONS: These data suggest that the development and implementation of a culturally congruent transplant program can positively affect Hispanic LDKT and thereby reduce Hispanics disparities in LDKT rates. Further studies are needed to prospectively evaluate the generalizability of implementing such culturally competent interventions at other transplant programs.

The impact of hospitalist discontinuity on hospital cost, readmissions, and patient satisfaction.

BACKGROUND: Achieving patient-physician continuity is difficult in the inpatient setting, where care must be provided continuously. Little is known about the impact of hospital physician discontinuity on outcomes. OBJECTIVE: To determine the association between hospital physician continuity and percentage change in median cost of hospitalization, 30-day readmission, and patient satisfaction with physician communication. DESIGN: Retrospective observational study using various multivariable models to adjust for patient characteristics. PARTICIPANTS: Patients admitted to a non-teaching hospitalist service in a large, academic, urban hospital between 6 July 2008 and 31 December 2011. MAIN MEASURES: We used two measures of continuity: the Number of Physicians Index (NPI), and the Usual Provider of Continuity (UPC) index. The NPI is the total number of unique physicians caring for a patient, while the UPC is calculated as the largest number of patient encounters with a single physician, divided by the total number of encounters. Outcome measures were percentage change in median cost of hospitalization, 30-day readmissions, and top box responses to satisfaction with physician communication. KEY RESULTS: Our analyses included data from 18,375 hospitalizations. Lower continuity was associated with modest increases in costs (range 0.9-12.6 % of median), with three of the four models used achieving statistical significance. Lower continuity was associated with lower odds of readmission (OR = 0.95-0.98 across models), although only one of the models achieved statistical significance. Satisfaction with physician communication was lower, with less continuity across all models, but results were not statistically significant. CONCLUSIONS: Hospital physician discontinuity appears to be associated with modestly increased hospital costs. Hospital physicians may revise plans as they take over patient care responsibility from their colleagues.

Relationship of meeting physical activity guidelines with health-related utility.

OBJECTIVE: Health-related utility measures overall health status and quality of life and is commonly incorporated into cost-effectiveness analyses. This study investigates whether attainment of federal physical activity guidelines translates into better health-related utility in adults with or at risk for knee osteoarthritis (OA). METHODS: Cross-sectional data from 1,908 adults with or at risk for knee OA participating in the accelerometer ancillary study of the Osteoarthritis Initiative were assessed. Physical activity was measured using 7 days of accelerometer monitoring and was classified as 1) meeting guidelines (≥150 bouted moderate-to-vigorous [MV] minutes per week); 2) insufficiently active (≥1 MV bout[s] per week but below guidelines); or 3) inactive (zero MV bouts per week). A Short Form 6D health-related utility score was derived from patient-reported health status. Relationship of physical activity levels to median health-related utility adjusted for socioeconomic and health factors was tested using quantile regression. RESULTS: Only 13% of participants met physical activity guidelines, and 45% were inactive. Relative to the inactive group, median health-related utility scores were significantly greater for the meeting guidelines group (0.063; 95% confidence interval [95% CI] 0.055, 0.071) and the insufficiently active group (0.059; 95% CI 0.054, 0.064). These differences showed a statistically significant linear trend and strong cross-sectional relationship with physical activity level even after adjusting for socioeconomic and health factors. CONCLUSION: We found a significant positive relationship between physical activity level and health-related utility. Interventions that encourage adults, including persons with knee OA, to increase physical activity even if recommended levels are not attained may improve their quality of life.

How accurately are we coding readmission diagnoses after total joint arthroplasty?

Readmission rates have been cited as an important quality measure in the Affordable Care Act. Accordingly, understanding and accurately tracking the causes for readmission will be increasingly important. We queried an electronic database for all patients who underwent primary THA or TKA at our institution from 2006 through 2010. We identified those readmitted within 90 days of surgery and analyzed 87 random de-identified medical records. We then assigned a clinical diagnosis for each readmission, which was then compared with the coder-derived diagnosis by ICD-9 code. The overall 90-day readmission rate was 7.9%. We identified 22 of 87 patients for whom there was disagreement (25.3%, 95% CI=16.6-35.8%). The most common were procedure-related complications. Coded diagnoses frequently did not correlate with the physician-derived diagnoses. The unverified use of coded readmission diagnoses in calculating quality measures may not be clinically relevant.

Relationship between physical activity and health-related utility among knee osteoarthritis patients.

OBJECTIVE: To estimate the relationship between physical activity and health-related utility for people with knee osteoarthritis (OA) and implications for designing cost-effective interventions. METHODS: We used generalized estimating equation regression analysis to estimate partial association of accelerometer-measured physical activity levels with health-related utility after controlling for demographics, health status, knee OA severity level, pain, and functioning. RESULTS: Moving from the lowest to the middle tertile of physical activity level was associated with a 0.071 (P < 0.01) increase in health-related utility after controlling for demographics and a 0.036 (P < 0.05) increase in utility after controlling for demographics, health status, knee OA severity level, weight, pain, and functional impairments. CONCLUSION: Intervention programs that move individuals out of the lowest tertile of physical activity have the potential to be cost effective.

Improving teamwork: impact of structured interdisciplinary rounds on a hospitalist unit.

BACKGROUND: Effective collaboration and teamwork is essential in providing safe and effective care. Research reveals deficiencies in teamwork on medical units involving hospitalists. OBJECTIVE: The aim of this study was to assess the impact of an intervention, Structured Inter-Disciplinary Rounds (SIDR), on nurses' ratings of collaboration and teamwork. METHODS: The study was a controlled trial involving an intervention and control hospitalist unit. The intervention, SIDR, combined a structured format for communication with a forum for regular interdisciplinary meetings. We asked nurses to rate the quality of communication and collaboration with hospitalists using a 5-point ordinal scale. We also assessed teamwork and safety climate using a validated instrument. Multivariable regression analyses were used to assess the impact on length of stay (LOS) and cost using both a concurrent and historic control. RESULTS: A total of 49 of 58 (84%) nurses completed surveys. A larger percentage of nurses rated the quality of communication and collaboration with hospitalists as high or very high on the intervention unit compared to the control unit (80% vs. 54%; P = 0.05). Nurses also rated the teamwork and safety climate significantly higher on the intervention unit (P = 0.008 and P = 0.03 for teamwork and safety climate, respectively). Multivariable analyses demonstrated no difference in the adjusted LOS and an inconsistent effect on cost. CONCLUSIONS: SIDR had a positive effect on nurses' ratings of collaboration and teamwork on a hospitalist unit, yet no impact on LOS and cost. Further study is required to assess the impact of SIDR on patient safety measures.

Assessing patient perceptions of hospitalist communication skills using the Communication Assessment Tool (CAT).

BACKGROUND: Hospitalists care for an increasing percentage of hospitalized patients, yet evaluations of patient perceptions of hospitalists' communication skills are lacking. OBJECTIVE: Assess hospitalist communication skills using the Communication Assessment Tool (CAT). METHODS: A cross-sectional study of patients, age 18 or older, admitted to the hospital medicine service at an urban, academic medical center with 873 beds. Thirty-five hospitalists assigned to both direct care and teaching service were assessed. MEASUREMENTS: Hospitalist communication was measured with the CAT. The 14-item survey, written at a fourth grade level, measures responses along a 5-point scale ("poor" to "excellent"). Scores are reported as a percentage of "excellent" responses. RESULTS: We analyzed 700 patient surveys (20 for each of 35 hospitalists). The proportion of excellent ratings for each hospitalist ranged from 38.5% to 73.5%, with an average of 59.1% excellent (SD=9.5). Highest ratings on individual CAT items were for treating the patient with respect, letting the patient talk without interruptions, and talking in terms the patient can understand. Lowest ratings were for involving the patient in decisions as much as he or she wanted, encouraging the patient to ask questions, and greeting the patient in a way that made him or her feel comfortable. Overall scale reliability was high (Cronbach's alpha = 0.97). CONCLUSIONS: The CAT can be used to gauge patient perceptions of hospitalist communication skills. Many hospitalists may benefit from targeted training to improve communication skills, particularly in the areas of encouraging questions and involving patients in decision making.

Improving teamwork: impact of structured interdisciplinary rounds on a medical teaching unit.

BACKGROUND: Effective collaboration and teamwork is essential in providing safe and effective hospital care. Prior research reveals deficiencies in collaboration on medical teaching units. OBJECTIVE: The aim of this study was to assess the impact of an intervention, structured inter-disciplinary rounds (SIDR), on hospital care providers' ratings of collaboration and teamwork. METHODS: The study was a controlled trial comparing an intervention medical teaching unit with a similar control unit. The intervention, SIDR, combined a structured format for communication with a forum for regular interdisciplinary meetings. We surveyed providers on each unit and asked them to rate the quality of communication and collaboration they had experienced with other disciplines using a five-point ordinal scale. We also assessed the teamwork and safety climate using a validated instrument. Multivariable regression analyses were used to assess the impact on length of stay (LOS) and cost. RESULTS: One hundred forty-seven of 159 (92%) eligible providers completed the survey. Although resident physicians on each unit rated the quality of communication and collaboration with nurses similarly, a greater percentage of nurses gave high ratings to the quality of collaboration with resident physicians on the intervention unit as compared to the control unit (74% vs. 44%; p = 0.02). Providers on the intervention unit rated the teamwork climate significantly higher as compared to the control unit (82.4 +/- 11.7 vs. 77.3 +/- 12.3; p = 0.01). The difference was explained by higher teamwork climate ratings on the part of nurses on the intervention unit (83.5 +/- 14.7 vs. 74.2 +/- 14.1; p = 0.005). Ratings of the safety climate were not significantly different between units. Adjusted LOS and hospital costs were not significantly different between units. CONCLUSIONS: SIDR had a positive effect on nurses' ratings of collaboration and teamwork on a medical teaching unit. Further study is required to assess the impact of SIDR on patient safety measures.

Use of program evaluation in community youth tobacco cessation programs.

OBJECTIVE: To examine the inclusion of program evaluation components in a national sample of youth tobacco cessation programs. METHODS: Program administrators were interviewed to ascertain program characteristics associated with the inclusion of program evaluation components. RESULTS: Two thirds of all surveyed programs (n=591) had an evaluation component; most included attendance, user satisfaction, and quitting measures. Programs with an evaluation component were significantly more likely to report annual funding greater than the median and to conduct a follow-up with participants. CONCLUSION: Program characteristics and associated evaluation components are summarized, and recommendations are given for a minimal level of program evaluation planning.
