Multidisciplinary care program in pre-end-stage kidney disease from 2010 to 2018 in Taiwan

Pay-for-performance in Taiwan: A systematic review and meta-analysis of the empirical literature

OBJECTIVES

This study aimed to assess the impact of pay-for-performance (P4P) programmes on healthcare in Taiwan.

STUDY DESIGN

This was a systematic review and meta-analysis.

METHODS

A systematic literature search was performed using the PubMed, Medline, Embase, Cochrane review, Scopus, Web of Science and PsycINFO databases up to July 2023. Meta-analysis of the available outcomes was conducted using a random-effects model.

RESULTS

The search yielded 85 studies, of which 58 investigated the programme for diabetes mellitus (DM), eight looked at the programme for chronic kidney disease (CKD), and the remaining studies examined programmes for breast cancer, tuberculosis, schizophrenia and chronic obstructive pulmonary disease. The DM P4P programme was a cost-effective strategy associated with reduced hospitalisation and subsequent complications. The CKD P4P was associated with a lower risk of dialysis initiation. The P4P programme also improved outcomes in breast cancer, cure rates in tuberculosis, reduced admissions for schizophrenia and reduced acute exacerbation in chronic obstructive pulmonary disease. The meta-analysis revealed that the P4P programme for DM (odds ratio [OR] = 0.59; 95% confidence interval [CI] = 0.48-0.73) and CKD (OR = 0.73; 95% CI = 0.67-0.81) significantly reduced mortality risk. However, participation rate in the DM P4P programme was only 19% in 2014.

CONCLUSIONS

P4P programmes in Taiwan improve quality of care. However, participation was voluntary and the participation rate was very low, raising the concern of selective enrolment of participants (i.e. 'cherry-picking' behaviour) by physicians. Future programme reforms should focus on well-designed features with the aim of reducing healthcare disparities.

Late creation of vascular access increased post-hemodialysis mortality, hospitalization, and health-care expenditure: A population-based cohort study in Taiwan

BACKGROUND/PURPOSE

The optimal timing of vascular access (VA) creation for hemodialysis (HD) and whether this timing affects mortality and health-care utilization after HD initiation remain unclear. Thus, we conducted a population-based study to explore their association.

METHODS

We used Taiwan's National Health Insurance Research Database to analyze health-care outcomes and utilization in a cohort initiating HD during 2003-2013. We stratified patients by the following VA creation time points: >180, 91-180, 31-90, and ≤30 days before and ≤30 days after HD initiation and examined all-cause mortality, ambulatory care utilization/costs, hospital admission/costs, and total expenditure within 2 years after HD. Cox regression, Poisson regression, and general linear regression were used to analyze mortality, health-care utilization, and costs respectively.

RESULTS

We identified 77,205 patients who started HD during 2003-2013. Compared with the patients undergoing VA surgery >180 days before HD initiation, those undergoing VA surgery ≤30 days before HD initiation had the highest mortality-15.92 deaths per 100-person-years, crude hazard ratio (HR) 1.56, and adjusted HR 1.28, the highest hospital admissions rates- 2.72 admission per person-year, crude rate ratio (RR) 1.48 and adjusted RR 1.32, and thus the highest health-care costs- US$31,390 per person-year, 7% increase of costs and 6% increase with adjustment within the 2-year follow-up after HD initiation.

CONCLUSION

Late VA creation for HD can increase all-cause mortality, hospitalization, and health-care costs within 2 years after HD initiation. Early preparation of VA has the potential to reduce post-HD mortality and healthcare expenses for the ESKD patients.

The expert consensus on care and education for patients with diabetic kidney disease in Taiwan

Increasing prevalence of type 2 DM (T2DM) and diabetic kidney disease (DKD) has posed a great impact in Taiwan. However, guidelines focusing on multidisciplinary patient care and patient education remain scarce. By literature review and expert discussion, we propose a consensus on care and education for patients with DKD, including general principles, specifics for different stages of chronic kidney disease (CKD), and special populations. (i.e. young ages, patients with atherosclerotic cardiovascular disease or heart failure, patients after acute kidney injury, and kidney transplant recipients). Generally, we suggest performing multidisciplinary patient care and education in alignment with the government-led Diabetes Shared Care Network to improve the patients' outcomes for all patients with DKD. Also, close monitoring of renal function with early intervention, control of comorbidities in early stages of CKD, and nutrition adjustment in advanced CKD should be emphasized.

Novel equations incorporating the sarcopenia index based on serum creatinine and cystatin C to predict appendicular skeletal muscle mass in patients with nondialysis CKD

BACKGROUND & AIMS

Skeletal muscle mass measurements are important for customizing nutritional strategies for patients with chronic kidney disease (CKD). The serum creatinine-to-cystatin C ratio (Cr/CysC) is a potential indicator of sarcopenia. We developed simple equations to predict the appendicular skeletal muscle mass (ASM) of patients with CKD using readily available parameters and Cr/CysC.

METHODS

Overall, 573 patients with nondialysis CKD stages 3-5 were included for developing and validating the equations. The participants were randomly divided into development and validation groups in a 2:1 ratio. ASM was measured using the Body Composition Monitor (BCM), a multifrequency bioelectrical impedance spectroscopy device. The height, weight, anthropometric data, and handgrip strength (HGS) of the participants were obtained. Equations were generated using stepwise multiple linear regression models. The prognostic significance of the predicted ASM was evaluated in a CKD registry comprising 1043 patients.

RESULTS

The optimal equation without anthropometric data and HGS (Equation 1) was as follows: ASM (kg) = -7.949 - 0.049 × Age (years) - 2.213 × Woman + 0.090 × Height (cm) + 0.210 × Weight (kg) + 1.141 × Cr/CysC. The modified equation (Equation 2) with anthropometric data and HGS was as follows: ASM (kg) = -4.468 - 0.050 × Age (years) - 2.285 × Woman+ 0.079 × Height (cm) + 0.228 × Weight (kg) - 0.127 × Mid-arm muscular circumference (cm) + 1.127 × Cr/CysC. Both equations exhibited strong correlations with the ASM measured via BCM in the validation cohort (r = 0.944 and 0.943 for Equations 1 and 2, respectively) with minimal bias. When Equation 1 was applied to the CKD registry, the estimated ASM index (ASM/Height2) significantly predicted overall mortality over a median of 54 months.

CONCLUSIONS

Novel ASM equations offer a simple method for predicting skeletal muscle mass and can provide valuable prognostic information regarding patients with nondialysis CKD.

The Effects of Pharmacist-Led Medication Therapy Management on Medication Adherence and Use of Non-Steroidal Anti-Inflammatory Drug in Patients with Pre-End Stage Renal Disease

Purpose

Patients with chronic kidney disease (CKD) are particularly vulnerable to the risks of polypharmacy, largely owing to various comorbid conditions. This vulnerability is further compounded by an escalated risk of renal function deterioration when exposed to nephrotoxic medications. As part of the national health insurance program in Taiwan, the pre-end-stage kidney disease patient care and education plan has included pharmaceutical care since October 2021. This study aims to explore the effect of pharmacist involvement in a multidisciplinary care team for patients with kidney disease in outpatient settings.

Patients and Methods

This retrospective observational study was conducted at a single center. It analyzed data from May 2022 to May 2023, focusing on patients who received medication therapy management in the kidney disease pharmacist-managed clinic. The study assessed changes in patient medication adherence, non-steroidal anti-inflammatory drugs (NSAIDs) usage, CKD stage, and urine protein-to-creatinine ratio (UPCR) after pharmacist intervention. It also documented pharmacists' medication recommendations and the rate of acceptance by physicians.

Results

A total of 202 patients who had at least two clinic visits were included in the study. After pharmacist intervention, the proportion of poor medication adherence reduced significantly from 67.8% to 43.1% (p<0.001). The proportion of NSAID users also decreased significantly from 19.8% to 8.4% (p=0.001). CKD stage showed a significant reduction (p=0.007), and the average UPCR improved from 2828.4 to 2111.0 mg/g (p<0.001). The pharmacists provided a total of 56 medication recommendations, with an acceptance rate of 86%.

Conclusion

The involvement of pharmacists in the multidisciplinary care team can effectively provide medication-related recommendations, ensuring the effectiveness and safety of patients' medication use, and lead to better kidney function and lower proteinuria.

Prevalence and varieties of complementary and alternative medicine usage among individuals with pre-dialysis chronic kidney disease in Taiwan: an investigative cross-sectional analysis

BACKGROUND

Complementary and alternative medicine (CAM) is frequently used in the general population, yet only limited data are available regarding the prevalence of these medications in patients with chronic kidney disease (CKD). Hence, our study aimed to explore the prevalence and types of CAM in Taiwanese patients with CKD.

METHODS

A cross-sectional questionnaire survey was conducted by face-to-face interview of 275 pre-dialysis patients without dialysis treatment or kidney transplant at an outpatient nephrology clinic in Taiwan from March 2021 to June 2023. The study outcomes were the prevalence of CAM, CAM types, reasons for using CAM, and sources of information about CAM.

RESULTS

Overall, 128 patients (46.5%) were using CAM, but no significant differences from non-CAM users in the various CKD stages (p = 0.156) were found. CAM usage was high in the age range of 20-60 years and duration of CKD ≤ 5 years (p < 0.05). The most commonly used type of CAM was nutritional approaches (79.7%), followed by other complementary health approaches (26.6%). The most commonly utilized modalities of CAM were vitamins and minerals (38.3%), and only 27.1% of patients disclosed their CAM use to their physicians. The most common sources of information about CAM were family and friends, cited by 66% of the participants. Health promotion and a proactive attitude were reported by 40% of users as the reasons for using CAM.

CONCLUSIONS

The present study provides data on the CAM usage among CKD patients and adds to the increasing evidence on CAM use. Because some of these practices have safety concerns, better education from healthcare providers on the risks and benefits of CAM therapy is needed by CKD patients.

A quality improvement initiative for patients with chronic kidney disease to promote their smoking cessation

Cigarette smoking is a critical issue in caring for patients of chronic kidney disease (CKD). However, there is no routine care program designed for combining both smoking cessation and CKD care. The process of our quality improvement (QI) collaboration used data under our routine payment-for-performance for pre-end-stage renal disease (P4P Pre-ESRD) in Taichung Veterans General hospital from 2020 to 2022. We share our experience with a QI project that integrates the Ottawa model for smoking cessation (OMSC) with the Pre-ESRD care program as part of routine CKD care. The electronic health information systems were improved to reduce workload of medical staff. The number was more for both qualified CKD educators and nephrologists for smoking cessation. The access and availability for smoking cessation were immediate and convenient for patients. Specifically, all the actions were performed by CKD educators, with nephrologists overseeing the process in routine care. By combining OMSC with the Pre-ESRD program, we were able to provide smokers with satisfactory access and availability to smoking cessation services within our healthcare facility. The smoker cases found were more in number (206 in 2020, 344 in 2021, and 421 in 2022). Before the integrated OSTC-Pre-ESRD program (in 2020), the proportion of smokers was 3.88%. After implementing the integrated program, smokers increased significantly on a yearly basis (9.69% in 2021 and 9.82% in 2022). Finally, case numbers of on-site smoking cessations increased significantly after implementing the integrated system (0 in 2020, 17 in 2021, and 20 in 2022). All CKD patients for smoking cessation were also more (8 in 2020, 46 in 2021, and 38 in 2022). After implementing the QI program, focusing on the integrated OMSC-Pre-ESRD program, we found more smokers undergoing smoking cessation. This QI program highlighted the importance of better access and availability for smoking cessation.

Associations of air pollutant concentrations with longitudinal kidney function changes in patients with chronic kidney disease

This longitudinal cohort study investigated the associations of air pollutant exposures, including CO, NO, NO₂, NO_x, O₃, PM₁₀, PM_2.5, and SO₂, with long-term kidney function changes in patients with chronic kidney disease (CKD). We enrolled 447 CKD patients who took part in a universal hospital pre-ESRD care program during 2011-2015. The daily average air pollutant exposures and temperature were estimated for each patient, with different levels of air pollutant concentrations defined by 5-knot and restricted cubic spline function. Predicted annual estimated glomerular filtration (eGFR) slope values by one mixed model were considered as the study outcome. The average age of the study population was 77.1 ± 12.6 years, and the median annual eGFR decreased by 2.1 ml/min/1.73 m² per year from 30 ml/min/1.73 m² at baseline during a mean follow-up time of 3.4 years. The univariable and multivariable analyses revealed no significant linear and non-linear associations between 5-knot air pollutant concentrations and annual eGFR slope. In addition, the visualized spline effect plots show insignificant variation patterns in annual eGFR slope values with increased air pollutant concentrations. These results encourage more extensive studies to clarify the causal relationships and mechanisms of long-term specific air pollutant exposures and longitudinal kidney function change, especially in CKD populations.

Factors associated with poor sleep quality in patients with pre-dialysis chronic kidney disease: A systematic review

AIMS

To determine factors associated with poor sleep quality among patients with pre-dialysis chronic kidney disease.

DESIGN

This is a systematic review study guided by Preferred Reporting Items for Systematic Reviews and Meta-Analyses statements and checklist.

DATA SOURCES

Empirical evidence was sought in major electronic databases, including Embase, MEDLINE, CINAHL and Airiti library from March to September 2022.

REVIEW METHODS

Studies investigating factors associated with poor sleep quality among adult patients with chronic kidney disease were included. Study participants who received renal replacement therapy and had sleep disorders and serious illnesses such as cancer were excluded. Of the 526 studies that resulted from the search after removing duplicate articles, 20 studies were assessed for quality by using Joanna Briggs Institute and Newcastle-Ottawa Scale by two doctorial prepared nursing scientists.

RESULTS

A total of 20 studies were included in this review. The prevalence of poor sleep quality in these studies ranged from 11% to 97.5%. Demographics (older age and female), physiological conditions (higher body mass index, higher hip circumferences, higher systolic blood pressure, poor cardiovascular function, dyspnoea, pain, cramps, itchiness or moderate to extreme pruritus, lower fasting plasma glucose, electrolyte imbalance, higher total cholesterol and gastrointestinal symptoms), depression, smoking, arousal-related and cognitive arousal behaviours were associated with poor sleep quality.

CONCLUSION

Poor sleep quality was prevalent and influenced kidney function, increased mortality as well as decreased quality of life in patients with pre-dialysis chronic kidney disease. This review synthesizes factors associated with poor sleep quality. Managing these factors can mitigate and prevent poor sleep quality.

IMPACT

Healthcare providers, especially nurses, can assess the risk factors of poor sleep quality and reinforce patients' self-management. Future research should elucidate the assessment and management of risk factors and transfer these into widespread use in the routine care of patients with chronic kidney disease.

Artificial neural network-boosted Cardiac Arrest Survival Post-Resuscitation In-hospital (CASPRI) score accurately predicts outcome in cardiac arrest patients treated with targeted temperature management

Existing prognostic models to predict the neurological recovery in patients with cardiac arrest receiving targeted temperature management (TTM) either exhibit moderate accuracy or are too complicated for clinical application. This necessitates the development of a simple and generalizable prediction model to inform clinical decision-making for patients receiving TTM. The present study explores the predictive validity of the Cardiac Arrest Survival Post-resuscitation In-hospital (CASPRI) score in cardiac arrest patients receiving TTM, regardless of cardiac event location, and uses artificial neural network (ANN) algorithms to boost the prediction performance. This retrospective observational study evaluated the prognostic relevance of the CASPRI score and applied ANN to develop outcome prediction models in a cohort of 570 patients with cardiac arrest and treated with TTM between 2014 and 2019 in a nationwide multicenter registry in Taiwan. In univariate logistic regression analysis, the CASPRI score was significantly associated with neurological outcome, with the area under the receiver operating characteristics curve (AUC) of 0.811. The generated ANN model, based on 10 items of the CASPRI score, achieved a training AUC of 0.976 and validation AUC of 0.921, with the accuracy, precision, sensitivity, and specificity of 89.2%, 91.6%, 87.6%, and 91.2%, respectively, for the validation set. CASPRI score has prognostic relevance in patients who received TTM after cardiac arrest. The generated ANN-boosted, CASPRI-based model exhibited good performance for predicting TTM neurological outcome, thus, we propose its clinical application to improve outcome prediction, facilitate decision-making, and formulate individualized therapeutic plans for patients receiving TTM.

CKD Care Programs and Incident Kidney Failure: A Study of a National Disease Management Program in Taiwan

Rationale & Objective

Taiwan implemented national pay-for-performance programs for chronic kidney disease (CKD) care in 2006 and 2011; however, it is unknown whether this affected trends in maintenance dialysis. This study assessed the temporal trends in the incidence, prevalence, and mortality of individuals treated with maintenance dialysis from 2002-2016 in Taiwan.

Study Design

Follow-up study using Taiwan Renal Disease System Databases.

Setting & Participants

Participants who received dialysis for ≥90 days.

Predictors

Age, sex, and calendar year.

Outcomes

Incidence, prevalence of maintenance dialysis, or death, ascertained using the National Death Registry database.

Analytical Approach

The estimated annual percentage change was assessed by a generalized linear model, and the association of the programs with changes in the incidence of maintenance dialysis was evaluated using an age-period-cohort model.

Results

A total of 144,258 incident cases with a follow-up of 346 million person-years were analyzed during the observed periods. The estimated annual percentage change of the expected crude incidence rate was slightly reduced by 0.41% (95% CI, −1.06 to 0.24) and was more obvious in women and patients aged greater than 70 years; whereas, it was significantly increased in those aged greater than 75 years. After disentangling age and cohort effects, the implementation of the care programs was associated with an overall net drift of −1.09% (95% CI, −1.65 to −0.52) per year and a significant linear reduction in the period rate ratio from 1.06 (95% CI, 1.02-1.09) in the years 2002-2006 to 0.95 (95% CI, 0.92-0.98) in 2012-2016, using years 2007-2011 as reference.

Limitations

The findings of the study may have limited inferences to other countries with different health care systems.

Conclusions

The implementation of universal CKD care programs in Taiwan has significantly reduced the long-term trends in the incidence of maintenance dialysis; hence, devoting governmental resources to CKD care and prevention is advocated.
