    الوصف: The Patient-Reported Outcomes Measurement Information System (PROMIS) aims to address the lack of generalizable and universal measure of patient-reported outcomes to assess health-related quality of life. It has not been validated for patients with chronic kidney disease. We aim to validate the PROMIS-57 and PROMIS-29 questionnaires among kidney transplant recipients.A cross-sectional sample of stable kidney transplant recipients was recruited. Each participant completed PROMIS-57, a 57-question instrument covering seven domains-physical function, anxiety, depression, fatigue, pain, sleep disturbance, and social functioning-alongside validated legacy questionnaires [Patient Health Questionnaire (PHQ9), General Anxiety Disorder (GAD7), Edmonton Symptom Assessment Scale revised (ESASr), and Kidney Disease Quality of Life (KDQoL-36)]. PROMIS-29, a 29-question instrument, is nested within PROMIS-57 and measures the same domains. Structural validity of PROMIS was assessed with confirmatory factor analysis, reported using the Comparative Fit Index (CFI). Construct validity was assessed with known-groups comparisons. Internal consistency was evaluated with Cronbach's α and convergent validity was assessed with Spearman's Rho. Test-retest reliability was assessed through the intraclass correlation coefficient (ICC).Mean (± SD) age of the 177 participants was 50 (± 17), 57% were male and 55% Caucasian. Internal consistency of each domain was high (Cronbach's α 0.88). Confirmatory factor analysis showed good structural validity for most domains (CFI 0.95, RMSEA 0.05). Test-retest reliability indicated good agreement (ICC 0.6). Known-groups comparisons by clinical and socio-demographic differences were found as hypothesized.Our results provide evidence that PROMIS-57 and PROMIS-29 are highly reliable and valid instruments among kidney transplant recipients. We propose it as a valuable tool to assess important domains of the illness experience.

    الوصف: Author(s): Peipert, John D; Jennings, Lee A; Hays, Ron D; Wenger, Neil S; Keeler, Emmett; Reuben, David B | Abstract: ObjectivesTo better capture the scope of caregiver burden by creating a composite of 3 existing measures that assess different health domains.DesignProspective follow-up study.SettingUniversity-based dementia care management program.ParticipantsCaregivers of persons with dementia (PWD) (N=1,091).MeasurementsThe composite measure (the Dementia Burden Scale-Caregiver (DBS-CG)) was based on the Modified Caregiver Strain Index, Neuropsychiatric Inventory Questionnaire Distress Scale, and Patient Health Questionnaire (PHQ-9). Alternative factor structures were evaluated using 2 confirmatory factor analysis (CFA) models: a bifactor model and a 3 correlated factors model. Good model fit was defined as a root mean square error of approximation (RMSEA) of less than 0.06 and comparative fit index (CFI) value greater than 0.95. Coefficient omega was used to estimate scale reliability. Minimally important differences (MIDs) were estimated by anchoring the magnitude of DBS-CG change to change in caregiver self-efficacy and functional ability of PWD.ResultsThe bifactor CFA model fit best (RMSEA = 0.04, CFI = 0.95). Based on this model, a DBS-CG scale was created wherein all items were transformed to a possible range of 0 to 100 and then averaged. Higher scores indicate higher burden. Mean DBS-CG score was 27.3. The reliability was excellent (coefficient omega=0.93). MID estimates ranged from 4 to 5 points (effect sizes: 0.20-0.49).ConclusionThis study provides support for the reliability and validity of the DBS-CG. It can be used as an outcome measure to assess the effect of interventions to reduce dementia caregiver burden.

    الوصف: Rationale & Objective Compared with others, black and low-income patients receiving dialysis are less likely to receive kidney transplantation (KT) education within dialysis centers. We examined the efficacy of 2 supplementary KT education approaches delivered directly to patients. Study Design Prospective, 3-arm parallel-group, randomized, controlled trial. Settings & Participants Adult, black, and white low-income patients receiving dialysis in Missouri. Intervention Patients were randomly assigned to 1 of 3 educational conditions: (1) standard of care, usual KT education provided in dialysis centers (control); (2) Explore Transplant @ Home patient-guided, 4 modules of KT education sent directly to patients using print, video, and text messages; and (3) Explore Transplant @ Home educator-guided, the patient-guided intervention plus 4 telephonic discussions with an educator. Outcomes Primary: patient knowledge of living (LDKT) and deceased donor KT (DDKT). Secondary: informed decision making, change in attitudes in favor of LDKT and DDKT, and change in the number of new steps taken toward KT. Results In intent-to-treat analyses, patients randomly assigned to educator- and patient-guided interventions had greater knowledge gains (1.4 point increase) than control patients (0.8 point increase; P=0.02 and P=0.01, respectively). Compared with control patients, more patients randomly assigned to educator- and patient-guided interventions were able to make informed decisions about starting KT evaluation (82% vs 91% and 95%; P=0.003), pursuing DDKT (70% vs 84% and 84%; P=0.003), and pursuing LDKT (73% vs 91% and 92%; P Limitations Potential contamination because of patient-level randomization; no assessment of clinical end points. Conclusions Education presented directly to dialysis patients, with or without coaching by telephone, increased dialysis patients' KT knowledge and informed decision making without increasing educational burden on providers. Funding Source This project was funded by the National Institutes of Health and Health Resources and Services Administration. Trial Registration Registered at ClinicalTrials.gov with study number NCT02268682.

    الوصف: Author(s): McSorley, AMM; Peipert, JD; Gonzalez, C; Norris, KC; Goalby, CJ; Peace, LJ; Waterman, AD | Abstract: Although mandates require all dialysis patients be informed about transplant, Black and low-income patients remain less likely to receive transplant education, and significant racial and socioeconomic disparities in access to transplant persist. This mixed methods study, utilizing surveys and focus groups, examined 48 dialysis providers’ perceptions of transplant barriers for Black and low-income patients. Focus group transcripts were coded for common themes, which were organized by level of the Socio-Ecological Model for Transplant (SEMT). On surveys, over 50 percent of providers reported having insufficient time to provide transplant education. In focus groups, providers perceived that Black and low-income patients experience greater barriers to transplant. These perceptions, as well as limited time and resources, could enable subtle biases against comprehensive transplant education for these patient groups to emerge. Raising awareness among providers about existing biases and supplementing transplant education within dialysis centers may improve the consistency of education and access to transplant.

    الوصف: Patient reported measures (PRMs), including patient-reported outcomes, play a critical role in dialysis care. The usage of PRMs is extensive in dialysis clinics. While there are excellent PRMs to choose from, and their implementation as part of quality improvement and performance monitoring is extensive, there are still methodological challenges to be addressed. In this paper, we identify key methodological concerns around use of PRMs in dialysis centers in the United States and make recommendations for improving the use of PRMs in dialysis related to Selection of PRMs, Mode of Administration, and Support for PRM Use. These recommendations include: (1) Continue the use of Kidney Disease Quality of Life 36-item survey (KDQOL™-36) for dialysis centers’ internal quality improvement activities and the In-Center Hemodialysis Consumer Assessment of Health Care Providers and Systems (ICH-CAHPS survey®) for public dialysis center performance monitoring, but promote efforts to modify these instruments by incorporating PROMIS general health items (KDQOL-36) and reducing the length of the ICH-CAHPS. (2) Adopt a PRM of whether dialysis patients have been informed about all dialysis and transplant options. (3) Evaluate equivalence between electronic and paper versions of PRMs prior to widespread use of electronic administration. (4) Explore reimbursement of costs of PRM administration by the Centers for Medicare and Medicaid Services and kidney organizations. (5) Continue development of provider trainings in PRM administration and interpretation. These recommendations will help dialysis care decision-makers, clinicians, and applied researchers take the next steps toward enhancing PRM use in dialysis.

    الوصف: © 2017 by the American Society of Nephrology. Background and objectives Waitlist inactivity is a barrier to transplantation, because inactive candidates cannot receive deceased donor organ offers. We hypothesized that temporarily inactive kidney transplant candidates living in linguistically isolated communities would be less likely to achieve active waitlist status. Design, setting, participants, & measurements We merged Organ Procurement and Transplantation Network/ United Network for Organ Sharing data with five-digit zip code socioeconomic data from the 2000 US Census. The cumulative incidence of conversion to active waitlist status, death, and delisting before conversion among 84,783 temporarily inactive adult kidney candidates from 2004 to 2012 was determined using competing risks methods. Competing risks regression was performed to characterize the association between linguistic isolation, incomplete transplantation evaluation, and conversion to active status. A household was determined to be linguistically isolated if all members ≥14 years old speak a non-English language and also, speak English less than very well. ResultsA total of 59,147 candidates (70% of the studypopulation) achieved active status over the studyperiod of 9.8 years. Median follow-up was 110 days (interquartile range, 42–276 days) for activated patients and 815 days (interquartile range, 361–1244 days) for candidates not activated. The cumulative incidence of activation over the studyperiod was 74%, the cumulative incidence of death before conversion was 10%, and the cumulative incidence of delisting was 13%. After adjusting for other relevant covariates, living in a zip code with higher percentages of linguistically isolated households was associated with progressively lower subhazards of activation both in the overall population (reference

    الوصف: PURPOSE: End-stage renal disease patients’ experience of care is an integral part of the assessment of the quality of the care provided at hemodialysis centers and are needed to promote patient choice, quality improvement, and accountability. The purpose of this study is to evaluate the In-Center Hemodialysis Consumer Assessment of Healthcare Providers and Systems (ICH-CAHPS®) survey and its equivalence in different age, gender, race and education subgroups. METHODS: The ICH-CAHPS survey was administered to 1,454 patients from 32 dialysis facilities. For the characteristics compared, the sample had 756 participants younger than 65 years old, 739 men, 516 Black, 567 White, and 970 with less than high school diploma. Three different patient experience constructs were studied including nephrologist’s communication and caring, quality of care and operations, and providing information to patients. We used item response theory analysis to examine the possibility of differential item functioning (DIF) by patient age, gender, race and education separately after controlling for the other DIF characteristics and additional confounding variables including survey mode, mental and general health status as well as duration on dialysis. RESULTS: The three constructs studied were unidimensional and no major DIF was observed on the composites. Some non-equivalences were observed when confounders were not controlled for, suggesting that such covariates can be important factors in understanding the possibility of disparity in patients’ experience. CONCLUSIONS: The ICH-CAHPS is a promising survey to elicit hemodialysis patients’ experience that has good psychometric properties and provides a standardized tool for assessing age, gender, race or education disparity.

    الوصف: BACKGROUND: The Kidney Disease Quality of Life 36-item short form survey (KDQOL-36) is a widely used, patient-reported outcome measure for patients on dialysis. Efforts to aid interpretation are needed. METHODS: We used a sample of 58,851 dialysis patients participating in the Medical Education Institute (MEI) KDQOL Complete program, and 443,947 patients from the US Renal Data System (USRDS) to develop the KDQOL-36 Summary Score (KSS) for the kidney-targeted KDQOL-36 scales (Burdens of Kidney Disease [BKD], Symptoms and Problems of Kidney Disease [SPKD], and Effects of Kidney Disease [EKD]). We also used the MEI and USRDS data to calculate normative values for the Short Form-12 Health Survey’s Physical Component Summary (PCS) and Mental Component Summary (MCS), and the KDQOL-36’s BKD, SPKD, and EKD scales for the United States dialysis population. We used confirmatory factor analysis (CFA) models for KDQOL-36 kidney-targeted items, evaluated model fit with the comparative fit index (CFI; >0.95 indicates good fit) and root-mean-squared error of approximation (RMSEA

    الوصف: Five-year survival on dialysis is only 40%, compared to 74% with a deceased donor kidney transplant (DDKT) and 87% with a living donor kidney transplant (LDKT). An American Society of Transplantation (AST) Consensus Conference recommended that patients with chronic kidney disease (CKD) Stages 3–5 have the opportunity to learn about and decide which treatment option is right for them, particularly about LDKT. However, early education about LDKT and DDKT outside of transplant centers is inconsistent and often poor, with patients in CKD 3 and 4 and ethnic/racial minorities even less likely to receive it. A new randomized control trial (RCT), in partnership with Kaiser Permanente Southern California (KPSC), will assess knowledge gaps and the effectiveness of a supplementary video-guided, print and technology-based education intervention for English- and Spanish-speaking patients in CKD Stages 3, 4, and 5 to increase LDKT knowledge and decision-making. To date, no published LDKT educational interventions have studied such a large and diverse CKD population. In this RCT, 1200 English and Spanish-speaking CKD Stage 3–5 patients will be randomly assigned to one of two education conditions: ET@Home or KPSC standard of care education. Randomization will be stratified by CKD stage and primary language spoken. Those in the ET@Home condition will receive brochures, postcards, DVDs, and text messages delivering educational content in modules over a six-month period. Baseline data collection will measure demographics, transplant derailers, and the amount of previous CKD and transplant education they have received. Changes in CKD and transplant knowledge, ability to make an informed decision about transplant, and self-efficacy to pursue LDKT will be captured with surveys administered at baseline and at six months. At the conclusion of the study, investigators will understand key knowledge gaps for patients along the CKD continuum and between patients who speak different languages and have assessed the effectiveness of both English- and Spanish-language supplementary education in increasing KPSC patients’ knowledge about the opportunities for and risks and benefits of LDKT. We hope this program will reduce disparities in access to transplant. ClinicalTrials.gov Identifier: NCT03389932; date registered: 12/26/2017.
