Dialysis withdrawal and symptoms of anxiety and depression: a prospective cohort study.

BACKGROUND: An important aspect of end-of-life decisions in dialysis patients is elective withdrawal from dialysis therapy. Several studies have shown that clinical factors, such as comorbidity, play a role in dialysis withdrawal. The role of symptoms of anxiety and depression is largely unknown. The. METHODS: A prospective multi-center study has been set up to investigate anxiety and depressive symptoms longitudinally in dialysis patients. Anxiety and depressive symptoms were investigated using the Beck Anxiety Inventory (BAI) and Beck Depression Inventory (BDI) as baseline. Adverse events, including dialysis withdrawal and mortality were registered during follow-up. Multivariable cox proportional hazard models were used with anxiety and depression as the independent variable and dialysis withdrawal as the outcome variable. Models included age, sex, ethnicity and a set of clinical comorbidities. RESULTS: A total of 687 patients were included between 2012 and 2017, with a median follow-up of 3.2 years. A total of 48 patients (7%) withdrew from dialysis therapy, and subsequently deceased. Anxiety and depressive symptoms at baseline showed an association with dialysis withdrawal with hazard ratios of 2.31 (1.09-4.88) for anxiety and 2.56 (1.27-5.15) for depressive symptoms, independent of somatic comorbidities. DISCUSSION: Withdrawal from dialysis therapy is associated with anxiety and depressive symptoms. Dialysis patients with more severe depressive and anxiety symptoms were more vulnerable for dialysis withdrawal. Insight in factors that play a role in dialysis withdrawal could aid patients and clinicians making an informed decision and develop clinical guidelines.

Patients' and providers' perspectives on medication relatedness and potential preventability of hospital readmissions within 30 days of discharge.

BACKGROUND: Hospital readmissions are increasingly used as an indicator of quality in health care. One potential risk factor of readmissions is polypharmacy. No studies have explored the patients' perspectives on the medication relatedness and potential preventability of their readmissions. OBJECTIVE: To compare the patients' perspectives on the medication relatedness and potential preventability of their readmissions with the providers' perspectives. METHODS: Patients unplanned readmitted within 30 days after discharge at one of the participating departments of OLVG Hospital in Amsterdam were interviewed during their readmission. Patients' perspectives regarding medication relatedness of their readmissions, the potential preventability, possible preventable interventions, and satisfaction with medication information were examined. Health-care providers also reviewed files of these readmitted patients. Primary outcome was the percentage of medication-related and potentially preventable readmissions according to the patient vs the provider. Descriptive data analysis was used. RESULTS: According to patients, 36 of 172 (21%) readmissions were medication-related, and of these, 21 (58%) were potentially preventable. According to providers, 26 (15%) readmissions were medication-related and 6 (23%) of these were potentially preventable. Patients and providers agreed on the medication relatedness in 11 of the 172 readmissions, and in two of these, agreement on the potential preventability existed. According to patients, preventive interventions belonged mostly to the hospital level, followed by the primary care level and patient level. CONCLUSION: Patients and providers differ substantially on their perspectives regarding the medication relatedness and preventability of readmissions. Patients were more likely to view medication-related readmissions as preventable.

Anxiety Symptoms, Mortality, and Hospitalization in Patients Receiving Maintenance Dialysis: A Cohort Study.

RATIONALE & OBJECTIVE: Anxiety symptoms are common in dialysis patients and have a large impact on quality of life. The association of anxiety symptoms with adverse clinical outcomes in dialysis patients is largely unknown. This study examined the association of anxiety symptoms with hospitalization and mortality in patients receiving maintenance dialysis. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: Maintenance dialysis patients treated at 10 dialysis centers in the Netherlands between 2012 and 2016. EXPOSURES: Time-varying symptoms of anxiety and depression using the Beck Anxiety Inventory and Beck Depression Inventory. OUTCOMES: All-cause mortality, 1-year hospitalization rate, and hospital length of stay. ANALYTICAL APPROACH: Cox proportional hazards and Poisson regression models adjusted for sociodemographic and clinical variables. Sensitivity analyses included multiple imputation of missing data and restriction to incident patients only. RESULTS: 687 patients were included, composed of 433 prevalent and 242 incident dialysis patients. Median follow-up time was 3.1 (IQR, 3.0-3.5) years, during which 172 deaths occurred. 22% of patients had anxiety symptoms and 42% had depressive symptoms. Anxiety symptoms were associated with all-cause mortality and 1-year hospitalization rate and length of stay in all multivariable models. Anxiety symptoms showed a clear dose-response relationship with mortality. LIMITATIONS: Depression and anxiety often coexist and share symptoms. The observational design of this study limits inferences about causal mechanisms between anxiety and clinical outcomes. CONCLUSIONS: Anxiety symptoms are independently associated with increased risk for mortality and 1-year hospitalization. Anxiety symptoms are a clinically relevant risk factor for morbidity and mortality in dialysis patients and warrant further research on effective treatment.

Dimensions of Depressive Symptoms and Their Association With Mortality, Hospitalization, and Quality of Life in Dialysis Patients: A Cohort Study.

OBJECTIVE: Unraveling specific dimensions of depressive symptoms may help to improve screening and treatment in dialysis patients. We aimed to identify the best-fitting factorial structure for the Beck Depression Inventory-II (BDI) in dialysis patients and to assess the relation of these structure dimensions with quality of life (QoL), hospitalization, and mortality. METHODS: This prospective study included chronic dialysis patients from 10 dialysis centers in five hospitals between 2012 and 2017. Dimensions of depressive symptoms within the BDI were analyzed using confirmatory factor analysis. To investigate the clinical impact of these dimensions, the associations between symptom dimensions and QoL, hospitalization rate, and mortality were investigated using logistic, Poisson, and Cox proportional hazard regression models. Multivariable regression models included demographic, social, and clinical variables. RESULTS: In total, 687 dialysis patients were included. The factor model that included a general and a somatic factor provided the best-fitting structure of the BDI-II. Only the somatic dimension scores were associated with all-cause mortality (hazard ratio of 1.7 [1.2-2.5], p < .007) in the multivariable model. All dimensions were associated with increased hospitalization rate and reduced QoL. CONCLUSIONS: The somatic dimension of the BDI-II in dialysis patients was associated with all-cause mortality, increased hospitalization rate, and reduced QoL. Other dimensions were associated with hospitalization rate and decreased QoL. These findings show that symptom dimensions of depression have differential association with adverse clinical outcomes. Future studies should take symptom dimensions into account when investigating depression-related pathways, screening, and treatment effects in dialysis patients.

The (cost) effectiveness of guided internet-based self-help CBT for dialysis patients with symptoms of depression: study protocol of a randomised controlled trial.

BACKGROUND: Only a minority of dialysis patients with depressive symptoms are diagnosed and receive treatment. Depressive symptoms are highly prevalent in this population and are associated with adverse clinical outcomes. Underlying factors for this undertreatment may be the lack of evidence for the safety and effectivity of antidepressant medication, the reluctance of patients to adhere to antidepressant medication, the lack of mental healthcare provision in somatic healthcare environments and end-stage renal disease (ESRD) related physical limitations that complicate face-to-face psychotherapy. Guided Internet-based self-help treatment has demonstrated to be effective for depressive symptoms in other chronic patient populations and may overcome these barriers. The aim of this study is to investigate the (cost) effectiveness of a guided Internet-based self-help intervention for symptoms of depression in dialysis patients. METHODS: This study is a cluster randomized controlled trial (RCT) that investigates the effectiveness of a 5-week Internet-based self-help Problem Solving Therapy (PST) for depressive symptoms in dialysis patients. Depressive symptoms will be measured using the Beck Depression Inventory - second edition (BDI-II), with a cut-off score of ≥10. We aim to include 206 dialysis patients with depressive symptoms who will be cluster randomized to the intervention or the Care as Usual (CAU) control group. Secondary outcomes will include anxiety symptoms, quality of life, economic costs and clinical outcomes, such as inflammatory factors and hair cortisol levels. Assessments will take place at baseline (T0), 2 weeks after intervention (T1) and 6 months (T2), 12 months (T3) and 18 months (T4) after intervention. The control group will be measured at the same time points. Analysis will be based on the intention-to-treat principle. Mixed models will be used to assess the changes within each condition between pre-treatment and post-treatment. DISCUSSION: If demonstrated to be (cost) effective, Internet-based PST will offer new possibilities to treat dialysis patients with depressive symptoms and to improve their quality of care. TRIAL REGISTRATION: Dutch Trial Register: Trial NL6648 (NTR6834) (prospectively registered 13th November 2017).

The effect of a pharmaceutical transitional care program on rehospitalisations in internal medicine patients: an interrupted-time-series study.

BACKGROUND: Medication errors at transition of care can adversely affect patient safety. The objective of this study is to determine the effect of a transitional pharmaceutical care program on unplanned rehospitalisations. METHODS: An interrupted-time-series study was performed, including patients from the Internal Medicine department using at least one prescription drug. The program consisted of medication reconciliation, patient counselling at discharge, and communication to healthcare providers in primary care. The primary outcome was the proportion of patients with an unplanned rehospitalisation within six months post-discharge. Secondary outcomes were drug-related hospital visits, drug-related problems (DRPs), adherence, believes about medication, and patient satisfaction. Interrupted time series analysis was used for the primary outcome and descriptive statistics were performed for the secondary outcomes. RESULTS: In total 706 patients were included. At 6 months, the change in trend for unplanned rehospitalisations between usual care and the program group was non-significant (- 0.2, 95% CI -4.9;4.6). There was no significant difference for drug-related visits although visits due to medication reconciliation problems occurred less often (4 usual care versus 1 intervention). Interventions to prevent DRPs were present for all patients in the intervention group (mean: 10 interventions/patient). No effect was seen on adherence and beliefs about medication. Patients were significantly more satisfied with discharge counselling (68.9% usual care vs 87.1% program). CONCLUSIONS: The transitional pharmaceutical care program showed no effect on unplanned rehospitalisations. This lack of effect is probably because the reason for rehospitalisations are multifactorial while the transitional care program focused on medication. There were less hospital visits due to medication reconciliation problems, but further large scale studies are needed due to the small number of drug-related visits. (Dutch trial register: NTR1519).

The Stability of Type D Personality in Dialysis Patients.

PURPOSE: Type D personality has been identified as an independent risk factor for survival in cardiovascular disease (CVD) patients. As CVD is present in about 50% of dialysis patients, it is of clinical interest to assess the prevalence of type D personality, the association with depressive and anxiety symptoms, and stability of type D personality in dialysis patients. METHODS: Data was used from two consecutive measurements of the DIVERS study, a prospective cohort study among chronic dialysis patients in the Netherlands. Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), and the Type D Scale-14 (DS14) were used to assess depressive and anxiety symptoms and type D personality, respectively. The association of type D personality was assessed with analysis of variance F test. Stability of type D personality, depressive, and anxiety symptoms were determined by calculating Cohen's κ, and by determining the positive agreement. RESULTS: In total, 349 patients were included of which 249 patients had two measurement points. The prevalence of type D personality was 21% and type D personality was associated with depressive and anxiety symptoms (P < 0.01). Over a 6-month period, Cohen's κ was 0.52, 0.56, and 0.61 for type D personality, depressive, and anxiety symptoms, respectively. Sixty-one, 73, and 73% had a stable type-D personality, depressive, and anxiety symptoms, respectively. CONCLUSION: The presence of type D personality varies over time in dialysis patients. Therefore, type D personality is possibly more a state instead of a trait phenomenon.

Differences in survival on chronic dialysis treatment between ethnic groups in Denmark: a population-wide, national cohort study.

BACKGROUND: In Western countries, black and Asian dialysis patients experience better survival compared with white patients. The aim of this study is to compare the survival of native Danish dialysis patients with that of dialysis patients originating from other countries and to explore the association between the duration of residence in Denmark before the start of dialysis and the mortality on dialysis. METHODS: We performed a population-wide national cohort study of incident chronic dialysis patients in Denmark (≥18 years old) who started dialysis between 1995 and 2010. RESULTS: In total, 8459 patients were native Danes, 344 originated from other Western countries, 79 from North Africa or West Asia, 173 from South or South-East Asia and 54 from sub-Saharan Africa. Native Danes were more likely to die on dialysis compared with the other groups (crude incidence rates for mortality: 234, 166, 96, 110 and 53 per 1000 person-years, respectively). Native Danes had greater hazard ratios (HRs) for mortality compared with the other groups {HRs for mortality adjusted for sociodemographic and clinical characteristics: 1.32 [95% confidence interval (CI) 1.14-1.54]; 2.22 [95% CI 1.51-3.23]; 1.79 [95% CI 1.41-2.27]; 2.00 [95% CI 1.10-3.57], respectively}. Compared with native Danes, adjusted HRs for mortality for Western immigrants living in Denmark for ≤10 years, >10 to ≤20 years and >20 years were 0.44 (95% CI 0.27-0.71), 0.56 (95% CI 0.39-0.82) and 0.86 (95% CI 0.70-1.04), respectively. For non-Western immigrants, these HRs were 0.42 (95% CI 0.27-0.67), 0.52 (95% CI 0.33-0.80) and 0.48 (95% CI 0.35-0.66), respectively. CONCLUSIONS: Incident chronic dialysis patients in Denmark originating from countries other than Denmark have a better survival compared with native Danes. For Western immigrants, this survival benefit declines among those who have lived in Denmark longer. For non-Western immigrants, the survival benefit largely remains over time.

Short-Form 12 or Short-Form 36 to measure quality-of-life changes in dialysis patients?

BACKGROUND: Short-Form 36 (SF-36) is a self-report health-related quality-of-life (HRQOL) questionnaire, widely used in dialysis patients. It consists of physical and mental component scores (PCS/MCS), ranging from 0 to 100. To improve efficiency, the Short-Form 12 (SF-12) was developed to reproduce PCS and MCS. We assessed the ability of SF-12 versus SF-36 to detect change over time, and the association of SF-12 versus SF-36 with short-term and long-term mortality in dialysis patients. METHODS: Patients were selected from the Netherlands Cooperative Study on the Adequacy of Dialysis (N = 1379), a prospective follow-up study among incident dialysis patients (62.1% HD) who completed SF-36 measurements every 6 months. Changes in scores of SF-12 versus SF-36 were compared with intra-class correlation coefficients (ICCs). Subsequently, Bland-Altman plots were used to assess limits of agreement. Relationship with mortality was assessed with Cox models with and without a time-dependent variable, adjusted for age, sex, ethnicity, comorbidity and dialysis modality at baseline. RESULTS: ICC for change in scores was 0.90 for MCS and 0.84 for PCS. Mean difference was -0.1 and 0.2, respectively, and limits of agreement were -8.3 to 8.4 for MCS change in scores and -8.8 to 9.2 for PCS. Adjusted hazard ratio's for mortality per 5 units increment were 0.87 (95% CI: 0.84-0.91) for MCS12, 0.87 (95% CI: 0.84-0.90) for MCS36, 0.79 (95% CI: 0.76-0.83) for PCS12 and 0.75 (95% CI: 0.71-0.78) for PCS36. CONCLUSIONS: SF-12 can be used to detect change in HRQOL in cohort studies on dialysis patients. SF-12 and SF-36 were similarly associated with short-term and long-term mortality. However, the wide limits of agreement indicate that SF-12 and SF-36 can give different scores on the individual level, suggesting that for individual purposes SF-36 instead of SF-12 should be used.

Association of depressive and anxiety symptoms with adverse events in Dutch chronic kidney disease patients: a prospective cohort study.

BACKGROUND: Depressive symptoms have been reported to be associated with adverse clinical outcome in patients with chronic kidney disease (CKD) not on dialysis. This association has not been examined in Europe. Anxiety and depressive symptoms often co-occur. However, as yet there are no data concerning a possible association of anxiety symptoms with adverse clinical outcome. We examined the association of depressive and anxiety symptoms with adverse clinical outcome in Dutch CKD patients not on dialysis. METHODS: In this 3-year follow-up prospective cohort study, CKD patients not on dialysis with an estimated glomerular filtration rate (eGFR) ≤ 35 ml/min/1.73 m(2) from an urban teaching hospital were selected. Symptoms of depression and anxiety were evaluated using the Beck Depression Inventory (BDI) and the Beck Anxiety Inventory (BAI). Cox proportional hazards models were used to calculate hazard ratio's (HRs) with a composite event of death, initiation of dialysis, and hospitalization as outcome. HRs were adjusted for age, gender, diabetes, cardiovascular disease and eGFR. RESULTS: Of 100 included CKD patients depressive and anxiety symptoms were present in 34 and 31 %, respectively. Adjusted HRs for the composite event for patients with depressive and anxiety symptoms were 2.0 (95 % confidence interval (CI) 1.2-3.5) and 1.6 (95 % CI 0.9-2.7), respectively. Twenty three patients had both depressive and anxiety symptoms of whom adjusted HRs were 2.2 (95 % CI 1.2-4.0) for a composite event. CONCLUSIONS: Depressive and anxiety symptoms are common in patients with CKD in The Netherlands. Depressive symptoms are associated with an increased risk of poor clinical outcome. Anxiety symptoms show a trend for an increased risk of poor clinical outcome. There seems to be no additive effect of anxiety symptoms in addition to depressive symptoms with regard to poor clinical outcome.

Need for prolonged immunosupressive therapy in CLIPPERS--a case report.

BACKGROUND: Chronic lymphocytic inflammation with pontine perivascular enhancement responsive to steroids (CLIPPERS) was first described in 2010 by Pittock and colleagues. All reported patients presented with diplopia and gait ataxia and had similar typical MRI findings with punctuate gadolinium enhancement of the pons. Alternative diagnoses were excluded by means of laboratory, radiological and histological tests. All patients were successfully treated with steroids. We present a case in which the steroid therapy was switched to long term immunosuppressive therapy, leading to several severe side-effects, but sustained clinical improvement. CASE PRESENTATION: A 63-year-old male presented with sub-acute diplopia and progressive gait ataxia. During admission his neurological condition worsened and he developed multiple cranial nerve deficits, paraparesis and urine retention. MRI-findings were remarkable with punctuate enhancement with gadolinium of the pons. Cerebrospinal fluid only showed elevated protein levels and all other additional investigations were normal. The probable diagnosis of CLIPPERS was made and intravenous corticosteroids were administered. This led to rapid clinical recovery and decreased enhancement on the MRI-scan. Long-term oral immunosuppressive therapy was started. One-and-a-half year later our patient has no recurrence of neurological symptoms, however due to the side effects of the immunosuppressive therapy he was readmitted several times. CONCLUSION: CLIPPERS presents with distinctive clinical and MRI-findings and may be diagnosed after excluding other differential diagnoses. Patients are treated with corticosteroids with good clinical results. Since short term glucocorticoid treatment results into relapse of the disease, longer term immunosuppressive therapy appears to be mandatory for sustained improvement, although accompanied by severe side effects.

New consultants mastering the role of on-call supervisor: a longitudinal qualitative study.

CONTEXT: The supervision of specialty registrars during on-call shifts is essential to ensure the quality of both health care and medical education, but has been identified as a major novelty and stressor for new consultants in the transition from specialty training. There is a paucity of research on how consultants deal with their new supervisory roles and which factors influence this process. These issues are addressed in a prospective study designed to gather insights that can inform measures to ensure the provision of high-quality supervision and specialty training. METHODS: A longitudinal qualitative study was performed in the Netherlands. Semi-structured interviews were conducted with new consultants. The study was guided by an interpretative phenomenological approach until saturation was reached. At 3-month intervals between July 2011 and March 2012, eight novice consultants in internal medicine were interviewed three times each about their supervisory role while on call. Interviews focused on their preparation for the role in training, the actions they took to master the role, and their progression over time. RESULTS: Three interrelated domains of relevant factors emerged from the data: preparedness; personal characteristics, and contextual characteristics. Preparedness referred to the extent to which new consultants were prepared by training to take full responsibility for registrars' actions while supervising them from a distance. Personal characteristics, such as coping strategies and views on supervision, guided consultants' development as supervisors. Essential to this process were contextual characteristics, especially those concerning the extent to which the consultant knew the registrar, was familiar with departmental procedures, and had access to support from colleagues. CONCLUSIONS: New consultants should be prepared for their supervisory role by training and by being given a proper introduction to their workplace. The former requires progressive independence and exposure to supervisory tasks during specialty training; the latter requires an induction programme to enable new consultants to familiarise themselves with the departmental environment and the registrars they will be supervising.

The transition to hospital consultant: Denmark and the Netherlands compared on preparedness for practice, perceived intensity and contextual factors.

INTRODUCTION: Danish and Dutch new consultants' perceptions regarding the transition to consultant were compared to gain insight into this period, particularly the influence of contextual factors concerning the organisation of specialty training and health care therein. Preparation for medical and generic competencies, perceived intensity and burnout were compared. Additionally, effects of differences in working conditions and cultural dimensions were explored. METHODS: All consultants registered in the Netherlands in 2007-2009 (n = 2643) and Denmark in 2007-2010 (n = 1336) received in June 2010 and April 2011, respectively, a survey about their preparation for medical and generic competencies, perceived intensity and burnout. Power analysis resulted in required sample sizes of 542. Descriptive statistics and independent t-tests were used for analysis. RESULTS: Data were available of 792 new consultants in the Netherlands and 677 Danish new consultants. Compared to their Dutch counterparts, Danish consultants perceived specialty training and the transition less intensely, reported higher levels of preparation for generic competencies and scored lower on burnout. CONCLUSIONS: The importance of contextual aspects in the transition is underscored and shows that Denmark appears to succeed better in aligning training with practice. Regulations regarding working hours and progressive independence of trainees appear to facilitate the transition.

The transition to hospital consultant and the influence of preparedness, social support, and perception: A structural equation modelling approach.

BACKGROUND: Insight into the transition from specialist registrar to hospital consultant is needed to better align specialty training with starting as a consultant and to facilitate this transition. AIMS: This study investigates whether preparedness regarding medical and generic competencies, perceived intensity, and social support are associated with burnout among new consultants. METHOD: A population-based study among all 2643 new consultants in the Netherlands (all specialties) was conducted in June 2010. A questionnaire covering preparedness for practice, intensity of the transition, social support, and burnout was used. Structural equation modelling was used for statistical analysis. RESULTS: Data from a third of the population were available (32% n = 840) (43% male/57% female). Preparation in generic competencies received lower ratings than in medical competencies. A total of 10% met the criteria for burnout and 18% scored high on the emotional exhaustion subscale. Perceived lack of preparation in generic competencies correlated with burnout (r = 0.15, p < 0.001). No such relation was found for medical competencies. Furthermore, social support protected against burnout. CONCLUSIONS: These findings illustrate the relevance of generic competencies for new hospital consultants. Furthermore, social support facilitates this intense and stressful stage within the medical career.

Comparison of the SF-36 Five-item Mental Health Inventory and Beck Depression Inventory for the screening of depressive symptoms in chronic dialysis patients.

BACKGROUND: The Beck Depression Inventory (BDI) is a standard and validated questionnaire to screen for depressive symptoms in chronic dialysis patients, but is relatively extensive to use repeatedly in clinical practice. We investigated whether the five-item Mental Health Inventory (MHI-5) of the 36-item Short-Form Health Survey Questionnaire (SF-36) could be applied to screen for depressive symptoms in dialysis patients. Moreover, we determined the optimal MHI-5 cut-off score to assess depressive symptoms. METHODS: Chronic dialysis patients from three centres filled out the SF-36 and the BDI. A receiver operating characteristic (ROC) curve was constructed for the MHI-5 score with BDI ≥ 16 as reference standard to (i) calculate the area under the curve to determine whether the MHI-5 could be considered as a useful screening instrument for depressive symptoms and (ii) proxy the optimal cut-off score of the MHI-5 to assess depressive symptoms. The optimal cut-off score was determined by the value for which the sum of sensitivity and specificity had an optimum. RESULTS: Of 133 included patients, 23% had depressive symptoms as determined with BDI ≥ 16. The correlation of the BDI with MHI-5 was -0.64. The area under the ROC curve was 0.82 (95% confidence interval 0.74-0.90). The optimal cut-off point of the MHI-5 was 70. MHI-5 ≤ 70 had 77 sensitivity, 72 specificity, 44 positive predicting value and 91% negative predicting value with the presence of depressive symptoms determined with BDI ≥ 16. CONCLUSIONS: The MHI-5 may help clinicians to screen for depressive symptoms in dialysis patients without using an additional depression screening questionnaire once the SF-36 is completed. A cut-off value of 70 can be used safely for the purposes of screening applications.

The role of psychosocial factors in ethnic differences in survival on dialysis in the Netherlands.

INTRODUCTION: Ethnic minority patients on dialysis are reported to have better survival rates relative to Caucasians. The reasons for this finding are not fully understood and European studies are scarce. This study examined whether ethnic differences in survival could be explained by patient characteristics, including psychosocial factors. METHODS: We analysed data of the Netherlands Cooperative Study on the Adequacy of Dialysis study, an observational prospective cohort study of patients who started dialysis between 1997 and 2007 in the Netherlands. Ethnicity was classified as Caucasian, Black or Asian, assessed by local nurses. Data collected at the start of dialysis treatment included demographic, clinical and psychosocial characteristics. Psychosocial characteristics included data on health-related quality of life (HRQoL), mental health status and general health perception. Cox proportional hazards analysis was used to explore ethnic survival differences. RESULTS: One thousand seven hundred and ninety-one patients were Caucasian, 45 Black and 108 Asian. The ethnic groups differed significantly in age, residual glomerular filtration rate, diabetes mellitus, erythropoietin use, plasma calcium, parathormone and creatinine, marital status and general health perception. No ethnic differences were found in HRQoL and mental health status. Crude hazard ratios (HRs) for mortality for Caucasians compared to Blacks and Asians were 3.1 [95% confidence interval (CI) 1.6-5.9] and 1.1 (95% CI 0.9-1.5), respectively. After adjustment for a range of potential explanatory variables, including psychosocial factors, the HRs were 2.5 (95% CI 1.2-4.9) compared with Blacks and 1.2 (95% CI 0.9-1.6) compared with Asians. CONCLUSIONS: Although patient numbers were rather small, this study demonstrates, with 95% confidence, better survival for Black compared to Caucasian dialysis patients and equal survival for Asian compared to Caucasian dialysis patients in the Netherlands. This could not be explained by patient characteristics, including psychosocial factors.

Internet-based treatment for depressive symptoms in hemodialysis patients: A cluster randomized controlled trial.

OBJECTIVE: To investigate the effectiveness of a guided internet-based self-help intervention for hemodialysis patients with depressive symptoms. METHOD: Chronic hemodialysis patients from nine Dutch hospitals with a depression score on the Beck Depression Inventory - second edition (BDI-II) of ≥10, were cluster-randomized into a five modules guided internet-based self-help problem solving therapy intervention or a parallel care-as-usual control group. Clusters were based on hemodialysis shift. The primary outcome depression was measured with the BDI-II. Analysis was performed with linear mixed models. RESULTS: A total of 190 hemodialysis patients were cluster-randomized to the intervention (n = 89) or control group (n = 101). Post-intervention measurement was completed by 127 patients (67%) and more than half of the patients (54%) completed the intervention. No significant differences were found on the BDI-II score between the groups (mean difference - 0.1, 95%CI -3.0; 2.7, p = 0.94). Per protocol sensitivity analysis showed comparable results. No significant differences in secondary outcomes were observed between groups. CONCLUSIONS: Guided internet-based self-help problem solving therapy for hemodialysis patients with depressive symptoms does not seem to be effective in reducing these symptoms as compared to usual care. Future research should examine how to best design content and accessibility of an intervention for depressive symptoms in hemodialysis patients. TRIAL REGISTRATION: Dutch Trial Register: Trial NL6648 (NTR6834) (prospectively registered 13th November 2017).

Validation of Two Screening Tools for Anxiety in Hemodialysis Patients.

BACKGROUND: Symptoms of anxiety are often unrecognized and untreated in dialysis patients. We investigated the diagnostic accuracy of two widely used screening tools for anxiety in hemodialysis patients. METHODS: For this cross-sectional validation study, chronic hemodialysis patients from eight dialysis centers in the Netherlands were included. The Beck Anxiety Inventory (BAI) and Hospital Anxiety and Depression Scale-Anxiety subscale (HADS-A) were validated by the Mini International Neuropsychiatric Inventory (MINI) diagnostic interview. Receiver operating characteristic curves were used to determine the optimal cut-off values. RESULTS: Of 65 participants, 13 (20%) were diagnosed with one or more anxiety disorders on the MINI, of which 5 were included in the analysis. ROC curves showed a good diagnostic accuracy of the BAI and HADS-A. The optimal cut-off value for the BAI was ≥13 (sensitivity 100%, specificity 85%) and for the HADS-A was ≥10 (sensitivity 80%, specificity 100%). CONCLUSIONS: Based on our limited data, both the BAI and the HADS-A seem to be valid screening instruments for anxiety in hemodialysis patients that can be used in routine dialysis care. The HADS-A consists of fewer items and showed fewer false-positive results than the BAI, which might make it more useful in clinical practice.

Depression, anxiety and quality of life of hemodialysis patients before and during the COVID-19 pandemic.

OBJECTIVE: To investigate the impact of the coronavirus pandemic on mental health in hemodialysis patients, we assessed depression, anxiety and quality of life with valid mental health measures before and after the start of the pandemic. METHODS: Data were used from 121 hemodialysis patients from the ongoing prospective multicenter DIVERS-II study. COVID-19 related stress was measured with the Perceived Stress Scale - 10, depression with the Beck Depression Inventory - second edition (BDI-II)), anxiety with the Beck Anxiety Inventory (BAI) and quality of life with the Short Form - 12 (SF-12). Scores during the first and second COVID-19 wave in the Netherlands were compared to data prior to the pandemic with linear mixed models. RESULTS: No significant differences were found in BDI-II, BAI and SF-12 scores between before and during the pandemic. During the first wave, 33% of participants reported COVID-19 related stress and in the second wave 37%. These patients had higher stress levels (mean difference (MD) 4.7 (95%CI 1.5; 8.0), p = 0.005) and BDI-II scores (MD 4.9 (95%CI 0.7; 9.0), p = 0.021) and lower SF-12 mental component summary scores (MD -5.3 (95%CI -9.0, -1.6), p = 0.006) than patients who did not experienced COVID-19 stress. These differences were already present before the pandemic. CONCLUSION: The COVID-19 pandemic does not seem to influence mental health in hemodialysis patients. However, a substantial subgroup of patients with pre-existent mental health problems may be more susceptible to experience COVID-19 related stress.

Medication-Related Hospital Readmissions Within 30 Days of Discharge: Prevalence, Preventability, Type of Medication Errors and Risk Factors.

Background: Hospital readmission rates are increasingly used as a measure of healthcare quality. Medicines are the most common therapeutic intervention but estimating the contribution of adverse drug events as a cause of readmissions is difficult. Objectives: To assess the prevalence and preventability of medication-related readmissions within 30 days after hospital discharge and to describe the risk factors, type of medication errors and types of medication involved in these preventable readmissions. Design: A cross-sectional observational study. Setting: The study took place across the cardiology, gastroenterology, internal medicine, neurology, psychiatry, pulmonology and general surgery departments in the OLVG teaching hospital, Netherlands. Participants: Patients with an unplanned readmission within 30 days after discharge from an earlier hospitalization (index hospitalization: IH) were reviewed. Measurements: The prevalence and preventability of medication-related readmissions were assessed by residents in multidisciplinary meetings. A senior internist and hospital pharmacist reassessed the prevalence and preventability of identified cases. Generalized estimating equation with logistic regression was performed to identify risk factors of potentially preventable medication-related readmissions. Results: Of 1,111 included readmissions, 181 (16%) were medication-related, of which 72 (40%) were potentially preventable. The number of medication changes at IH (Adjusted odds ratio [ORadj]: 1.14; 95% CI: 1.05-1.24) and having ≥3 hospitalizations 6 months before IH (ORadj: 2.11; 95% CI: 1.12-3.98) were risk factors of a preventable medication-related readmission. Of these preventable readmissions, 35% were due to prescribing errors, 35% by non-adherence and 30% by transition errors. Medications most frequently involved were diuretics and antidiabetics. Conclusion: This study shows that 16% of readmissions are medication-related, of which 40% are potentially preventable. If the results are confirmed in larger multicentre studies, this may indicate that more attention should be paid to medication-related harm in order to lower the overall readmission rates.
