Prescribing errors in post - COVID-19 patients: prevalence, severity, and risk factors in patients visiting a post - COVID-19 outpatient clinic.

BACKGROUND: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has challenged healthcare globally. An acute increase in the number of hospitalized patients has necessitated a rigorous reorganization of hospital care, thereby creating circumstances that previously have been identified as facilitating prescribing errors (PEs), e.g. a demanding work environment, a high turnover of doctors, and prescribing beyond expertise. Hospitalized COVID-19 patients may be at risk of PEs, potentially resulting in patient harm. We determined the prevalence, severity, and risk factors for PEs in post-COVID-19 patients, hospitalized during the first wave of COVID-19 in the Netherlands, 3 months after discharge. METHODS: This prospective observational cohort study recruited patients who visited a post-COVID-19 outpatient clinic of an academic hospital in the Netherlands, 3 months after COVID-19 hospitalization, between June 1 and October 1 2020. All patients with appointments were eligible for inclusion. The prevalence and severity of PEs were assessed in a multidisciplinary consensus meeting. Odds ratios (ORs) were calculated by univariate and multivariate analysis to identify independent risk factors for PEs. RESULTS: Ninety-eight patients were included, of whom 92% had ≥1 PE and 8% experienced medication-related harm requiring an immediate change in medication therapy to prevent detoriation. Overall, 68% of all identified PEs were made during or after the COVID-19 related hospitalization. Multivariate analyses identified ICU admission (OR 6.08, 95% CI 2.16-17.09) and a medical history of COPD / asthma (OR 5.36, 95% CI 1.34-21.5) as independent risk factors for PEs. CONCLUSIONS: PEs occurred frequently during the SARS-CoV-2 pandemic. Patients admitted to an ICU during COVID-19 hospitalization or who had a medical history of COPD / asthma were at risk of PEs. These risk factors can be used to identify high-risk patients and to implement targeted interventions. Awareness of prescribing safely is crucial to prevent harm in this new patient population.

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.

Association of ethnicity and survival in peritoneal dialysis: a cohort study of incident patients in Brazil.

BACKGROUND: There are no available epidemiologic studies about the impact of ethnicity on outcomes of patients treated with peritoneal dialysis (PD) in South America. This study aims to assess the effect of ethnicity on the mortality of incident PD patients in Brazil. STUDY DESIGN: Prospective observational cohort study of incident patients treated with PD. SETTINGS & PARTICIPANTS: Patients 18 years or older who started PD therapy between December 2004 and October 2007 in 114 Brazilian dialysis centers. PREDICTORS: Self-reported ethnicity defined by the Brazilian Institute of Geography and Statistics as black and brown versus white patients and baseline demographic, socioeconomic, clinical, and laboratory data were collected at baseline. OUTCOME: Mortality, using cumulative mortality curves in which kidney transplantation and transfer to hemodialysis therapy were treated as competing end points. Multivariate Cox proportional hazards analysis was used to adjust for gradually more potential explanatory variables, censored for kidney transplantation and transfer to hemodialysis therapy. Analyses were performed for all patients, as well as stratified for elderly (aged ≥65 years) and nonelderly patients. RESULTS: 1,370 patients were white, 516 were brown, and 273 were black. The competing-risk model showed higher mortality in white patients compared with black and brown patients. With white patients as the reference, Cox proportional hazards analysis showed a crude HR for mortality of 0.77 (95% CI, 0.56-1.05) for black and 0.74 (95% CI, 0.59-0.94) for brown patients. After adjusting for potential explanatory factors, HRs were 0.67 (95% CI, 0.48-0.95) and 0.77 (95% CI, 0.43-1.01), respectively. The same results were observed in elderly and nonelderly patients. LIMITATIONS: Ethnicity was self-determined and some misclassification might have occurred. CONCLUSIONS: Black and brown Brazilian incident PD patients have a lower mortality risk compared with white patients.

Short-term versus long-term effects of depressive symptoms on mortality in patients on dialysis.

OBJECTIVE: Depressive symptoms seem to pose a risk factor for mortality among patients on dialysis. It is currently unknown whether the association is only short-lived and whether associations over time depend on specific causes of mortality. METHODS: In a prospective nationwide cohort study, 1528 patients with end-stage renal disease starting on dialysis completed the Mental Health Inventory. Patients were observed up to 5 years or until the end of follow-up in April 2011. Cox regression analyses were used to calculate associations between depressive symptoms and short-term (0-6 months), medium-term (6-24 months), or long-term (24-60 months) cardiovascular and noncardiovascular mortality. RESULTS: The adjusted hazard ratio (HR) was 1.43 (95% confidence interval [CI] = 1.08-1.88) for cardiovascular mortality and 2.07 (95% CI = 1.62-2.64) for noncardiovascular mortality. Depressive symptoms posed a strong risk factor for noncardiovascular mortality at the short term (HR = 2.82, 95% CI = 1.58-5.05), medium term (HR = 2.08, 95% CI = 1.40-3.09), and long term (HR = 1.84, 95% CI = 1.26-2.69), whereas the association between depressive symptoms and cardiovascular mortality was not observed during the first 6 months of follow-up (HR = 1.03, 95% CI = 0.49-2.15). CONCLUSIONS: Depressive symptoms at the start of dialysis therapy are associated with short-, medium-, and long-term mortality. The cause-specific mortality risk over time may help clinicians to understand multifactorial causes of the association between depressive symptoms and survival.

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.

An Interprofessional Student-Run Medication Review Program: The Clinical STOPP/START-Based Outcomes of a Controlled Clinical Trial in a Geriatric Outpatient Clinic.

As the population ages, more people will have comorbid disorders and polypharmacy. Medication should be reviewed regularly in order to avoid adverse drug reactions and medication-related hospital visits, but this is often not done. As part of our student-run clinic project, we investigated whether an interprofessional student-run medication review program (ISP) added to standard care at a geriatric outpatient clinic leads to better prescribing. In this controlled clinical trial, patients visiting a memory outpatient clinic were allocated to standard care (control group) or standard care plus the ISP team (intervention group). The medications of all patients were reviewed by a review panel ("gold standard"), resident, and in the intervention arm also by an ISP team consisting of a group of students from the medicine and pharmacy faculties and students from the higher education school of nursing for advanced nursing practice. For both groups, the number of STOPP/START-based medication changes mentioned in general practitioner (GP) correspondence and the implementation of these changes about 6 weeks after the outpatient visit were investigated. The data of 216 patients were analyzed (control group = 100, intervention group = 116). More recommendations for STOPP/START-based medication changes were made in the GP correspondence in the intervention group than in the control group (43% vs. 24%, P = < 0.001). After 6 weeks, a significantly higher proportion of these changes were implemented in the intervention group (19% vs. 9%, P = 0.001). The ISP team, in addition to standard care, is an effective intervention for optimizing pharmacotherapy and medication safety in a geriatric outpatient clinic.

Increased survival of immigrant compared to native dialysis patients in an urban setting in the Netherlands.

BACKGROUND: Data from the United States and Canada suggest that survival rates of Caucasian dialysis patients are lower compared to those of black patients and patients from Asian regions. Information regarding the survival rate of immigrant dialysis patients in Europe is scarce. METHODS: We retrospectively analysed incident haemodialysis (HD) and peritoneal dialysis (PD) patients who entered an Amsterdam renal service between January 1996 and December 2005. To explore the origin of differences in survival between natives and immigrants, we ran a series of Cox models with adjustment for demographic, clinical and laboratory variables at baseline and initial adequacy variables. RESULTS: Of 303 incident dialysis patients, 58% were natives and 42% were immigrants. Fifty-nine percent of natives and 54% of immigrants had HD as initial treatment modality. At initiation of dialysis, native patients were older and had higher rates of vascular and coronary artery diseases and malignancies and a lower prevalence of hypertension. Glomerulonephritis was more common among immigrants as primary kidney disease. Mean haematocrit and calcium levels for natives were higher compared to immigrants. Cox proportional hazards analysis revealed an increased relative mortality risk (RR) of 2.7 [95% confidence interval (CI) 1.9-3.9] for natives compared to immigrants. Adjustment for age at the start of dialysis attenuated the RR to 1.9 (CI 1.3-2.7). Adjustment for the other variables did not materially influence this RR. CONCLUSIONS: We demonstrate increased survival for immigrant compared to native dialysis patients in an urban setting in the Netherlands. This survival advantage is only partly explained by younger age of immigrants at the start of dialysis compared to native patients.

Depressive and Anxiety Symptoms in Dutch Immigrant and Native Dialysis Patients.

Due to continuing migration there is more interest in the mental health status of immigrants. The aim of this study is to determine the prevalence of depressive/anxiety symptoms in immigrant and native dialysis patients, and to explore if patient characteristics can explain differences. The Beck depression inventory and the beck anxiety inventory were used. Differences between native and immigrant patients were explored using logistic regression models adjusted for patient characteristics. The prevalence of depressive symptoms was 35% for 245 native patients and 50% for 249 immigrant patients. The prevalence of anxiety symptoms was 35% for native patients and 50% for immigrant patients. In addition, the prevalence for co-morbid depressive and anxiety symptoms was 20% for native patients and 32% for immigrant patients. Crude ORs for depressive/anxiety symptoms for immigrant patients versus native patients were 1.8 (1.2-2.5) and 1.7 (1.2-2.5), respectively. After adjustment for patient characteristics ORs remained the same. Clinicians should be aware that immigrant dialysis patients are more prone to develop depressive and anxiety symptoms. Cultural factors might play a role and should therefore be assessed in future research.

The association of acculturation and depressive and anxiety symptoms in immigrant chronic dialysis patients.

OBJECTIVE: Among immigrant chronic dialysis patients, depressive and anxiety symptoms are common. We aimed to examine the association of acculturation, i.e. the adaptation of immigrants to a new cultural context, and depressive and anxiety symptoms in immigrant chronic dialysis patients. METHODS: The DIVERS study is a prospective cohort study in five urban dialysis centers in the Netherlands. The association of five aspects of acculturation ("Skills", "Social integration", "Traditions", "Values and norms" and "Loss") and the presence of depressive and anxiety symptoms was determined using linear regression analyses, both univariate and multivariate. RESULTS: A total of 249 immigrant chronic dialysis patients were included in the study. The overall prevalence of depressive and anxiety symptoms was 51% and 47%, respectively. "Skills" and "Loss" were significantly associated with the presence of depressive and anxiety symptoms, respectively ("Skills" ß=0.34, CI: 0.11-0.58, and "Loss" ß=0.19, CI: 0.01-0.37; "Skills" ß=0.49, CI: 0.25-0.73, and "Loss" ß=0.33, CI: 0.13-0.53). The associations were comparable after adjustment. No significant associations were found between the other subscales and depressive and anxiety symptoms. CONCLUSION: This study demonstrates that less skills for living in the Dutch society and more feelings of loss are associated with the presence of both depressive and anxiety symptoms in immigrant chronic dialysis patients.

Differences in progression to ESRD between black and white patients receiving predialysis care in a universal health care system.

BACKGROUND AND OBJECTIVES: Studies performed in the United States showed that blacks progress from CKD to ESRD faster than do whites. Possible explanations are differences in health care system factors. This study investigated whether progression is also faster in a universal health care system, where all patients receive comparable care. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS: Data from the PREdialysis PAtient REcord study, a multicenter follow-up study of patients with CKD who started predialysis care in The Netherlands (1999-2011), were analyzed. Time-dependent Cox proportional hazards models were used to estimate the hazard ratio (HR) for starting renal replacement therapy (RRT), and linear mixed models were used to compare renal function decline (RFD) between blacks and whites. To explore possible mechanisms, analyses were adjusted for patient characteristics. RESULTS: At initiation of predialysis care, blacks (n=49) were younger and had more diabetes mellitus, higher proteinuria levels, and a higher estimated GFR than whites (n=946). Median follow-up time in months was similar (blacks: 13.9 [boundaries of interquartile range (IQR), 5.3 to 19.5]; whites: 13.1 [IQR, 5.1 to 24.0]). For blacks compared with whites, the crude HR for starting RRT within the first 15 months was 0.86 (95% confidence interval [CI], 0.55 to 1.34) and from 15 months onward, 1.93 (95% CI, 1.02 to 3.68), which increased after adjustment. RFD was faster by 0.18 (95% CI, 0.05 to 0.32) ml/min per 1.73 m(2) per month in blacks compared with whites. CONCLUSION: Blacks receiving predialysis care in a universal health care system have faster disease progression than whites, suggesting that health care system factors have a less influential role than had been thought in explaining black-white differences.

How baseline, new-onset, and persistent depressive symptoms are associated with cardiovascular and non-cardiovascular mortality in incident patients on chronic dialysis.

OBJECTIVE: Depressive symptoms are associated with mortality among patients on chronic dialysis therapy. It is currently unknown how different courses of depressive symptoms are associated with both cardiovascular and non-cardiovascular mortality. METHODS: In a Dutch prospective nation-wide cohort study among incident patients on chronic dialysis, 1077 patients completed the Mental Health Inventory, both at 3 and 12months after starting dialysis. Cox regression models were used to calculate crude and adjusted hazard ratios (HRs) for mortality for patients with depressive symptoms at 3months only (baseline only), at 12months only (new-onset), and both at 3 and 12months (persistent), using patients without depressive symptoms at 3 and 12months as reference group. RESULTS: Depressive symptoms at baseline only seemed to be a strong marker for non-cardiovascular mortality (HRadj 1.91, 95% CI 1.26-2.90), whereas cardiovascular mortality was only moderately increased (HRadj 1.41, 95% CI 0.85-2.33). In contrast, new-onset depressive symptoms were moderately associated with both cardiovascular (HRadj 1.66, 95% CI 1.06-2.58) and non-cardiovascular mortality (HRadj 1.46, 95% CI 0.97-2.20). Among patients with persistent depressive symptoms, a poor survival was observed due to both cardiovascular (HRadj 2.14, 95% CI 1.42-3.24) and non-cardiovascular related mortality (HRadj 1.76, 95% CI 1.20-2.59). CONCLUSION: This study showed that different courses of depressive symptoms were associated with a poor survival after the start of dialysis. In particular, temporary depressive symptoms at the start of dialysis may be a strong marker for non-cardiovascular mortality, whereas persistent depressive symptoms were associated with both cardiovascular and non-cardiovascular mortality.
