Utilization and Costs of Health Care in a Kidney Supportive Care Program

Health system related kidney supportive care interventions for adults with chronic kidney disease: A systematic review

INTRODUCTION

Kidney failure can be managed either conservatively or via kidney replacement therapy. Kidney supportive care combines the expertise of nephrology with palliative care in a multidisciplinary team with a focus on improving quality of life.

OBJECTIVE

To identify and appraise evidence-based health system kidney supportive care interventions DESIGN: Systematic review (PROSPERO Registration - CRD42022333650).

PARTICIPANTS

Adults with chronic kidney failure.

MEASUREMENTS

Six databases were searched, using terms "palliative care" and "chronic kidney disease" for publications between January 2010 and March 2024. The Cochrane "Effective Practice and Organisation of Care" and "Clinical Practice Guidelines for Quality Palliative Care" domains informed data extraction.

RESULTS

Of the 60 studies included, one-third were randomised controlled trials. The most common "Effective Practice and Organisation of Care" domain described was care delivery (58/60). End-of-life care (33/60), and physical aspects of care (19/60), were commonly described "Clinical Practice Guidelines for Quality Palliative Care" domains. Multidisciplinary shared care was highlighted in 26 studies. Least described domains were cultural (0/60) and ethical aspects (3/60). Almost 2/3 (39/60) of studies compared the outcomes of kidney supportive care interventions, and the most common outcome assessed was advance care planning (18/39). Key findings reported integrated palliative care reduced hospital admissions and costs, facilitated better patient-clinician communication, and improved symptom management. Gaps were identified in cultural and ethical/legal aspects of care.

CONCLUSIONS

The studies highlighted the effectiveness of kidney-supportive care interventions in improving patient outcomes, especially in end-of-life care and symptom management. However, significant existing gaps identified necessitate further research.

Higher levels of supportive care needs are linked to higher health service use and cost, poor quality of life, and high distress in patients with cirrhosis in Queensland, Australia

BACKGROUND

Australians with cirrhosis have significant practical and psychosocial needs. This longitudinal study examined the association between supportive care needs and health service use and costs, and patient outcomes from June 2017 to December 2018.

METHODS

The Supportive Needs Assessment tool for Cirrhosis (SNAC), quality of life (Chronic Liver Disease Questionnaire and Short Form 36), and distress (distress thermometer) were self-reported through an interview at recruitment (n=433). Clinical data were obtained from medical records and through linkage, and health service use and costs through linkage. Patients were grouped as by needs status. Rates of hospital admissions (per person days at risk) and costs were assessed by needs status [incidence rate ratios (IRR), Poisson regression]. Multivariable linear regression was used to assess the differences in SNAC scores by quality of life and distress. Multivariable models included Child-Pugh class, age, sex, recruitment hospital, living arrangements, place of residence, comorbidity burden, and primary liver disease etiology.

RESULTS

In adjusted analyses, compared with patients with low/no needs, patients with unmet needs had more cirrhosis-related admissions (adjusted IRR=2.11, 95% CI=1.48-3.13; p<0.001), admissions through the emergency department (IRR=2.99, 95% CI=1.80-4.97, p<0.001), and emergency presentations (IRR=3.57, 95% CI=1.41-9.02; p<0.001). Total hospitalization costs for cirrhosis admissions were higher for those with unmet needs ($431,242 per person days at risk) compared with those with met needs ($87,363 per person days at risk, adjusted cost ratio=3.52, 95%CI=3.49-3.54; p<0.001). In multivariable analysis, increasing overall mean SNAC scores (higher needs) were correlated with poorer quality of life and higher level of distress (p<0.001 for all comparisons).

CONCLUSIONS

Patients with cirrhosis and high unmet psychosocial needs and practical and physical needs have poor quality of life, high distress, and very high service use and costs, highlighting the importance of urgently addressing unmet needs.

Prevalence and Severity of Lower Gastrointestinal Symptoms amongst Non-Dialysis Chronic Kidney Disease Patients: A Systematic Review and Meta-Analysis

Chronic kidney disease (CKD) patients experience a wide range of symptoms that deteriorate their health-related quality of life (HRQoL). We aimed to estimate the prevalence and severity of lower gastrointestinal (GI) symptoms in non-dialysis CKD adult outpatients, and to summarize the relationships between these symptoms and HRQoL, laboratory test results, and clinical data. The protocol of the study was preregistered (PROSPERO CRD42021255122). We searched MEDLINE, Scopus, Web of Science, and grey literature sources from the databases' inception up until 27 November 2021. Wide citation chasing was conducted. Single proportions (prevalence of functional constipation, self-reported constipation, diarrhea, abdominal bloating, fecal incontinence, and abdominal/rectal pain) were pooled using generalized linear mixed models. A total of 37 studies with 12,074 patients were included. We found that lower GI symptoms, especially self-reported abdominal bloating [CKD G1-2: 48.45% (95% CI: 43.5-53.4%; 2 studies); G3: 46.95% (95% CI: 45.0-48.9%; 2 studies), G4-5: 36.1% (95% CI: 25.4-48.5%; 8 studies)] and constipation [CKD G1-2: 31.8% (95% CI: 13.9-54.9%); G3: 29.8% (95% CI: 21.2-40.1%; 4 studies); G4-5: 38.8% (95% CI: 30.9-47.4%); 22 studies)], were common in non-dialysis CKD patients. The severity of the symptoms was limited. Self-reported constipation was most consistently associated with worse HRQoL, whereas hard stool consistency was associated with higher uremic toxins levels. To conclude, since lower GI symptoms are common in CKD, using symptom questionnaires that do not take them into account cannot provide full insight into the patient's experience. Further studies are needed to cover identified knowledge gaps, including the exploration of the pathophysiology of GI symptoms in CKD with multi-omics data.

Identification of factors associated with high-cost use of inpatient care in chronic kidney disease: a registry study

OBJECTIVE

To explore factors behind inpatient admissions by high-cost users (HCUs) in pre-end-stage chronic kidney disease (CKD).

DESIGN

Retrospective analysis of CKD.QLD Registry and hospital admissions of the Queensland Government Department of Health recorded between 1 July 2011 and 30 June 2016.

SETTING

Queensland public and private hospitals.

PARTICIPANTS

5096 individuals with CKD who consented to the CKD.QLD Registry via 1 of 11 participating sites.

MAIN OUTCOMES

Associations of HCU status with patient characteristics, pathways and diagnoses behind hospital admissions at 12 months.

RESULTS

Age, advanced CKD, primary renal diagnosis, cardiovascular disease and hypertension were predictors of the high-cost outcome. HCUs were more likely than non-HCUs to be admitted by means of episode change (relative risk: 5.21; 95% CI 5.02 to 5.39), 30-day readmission (2.19; 2.13 to 2.25), scheduled readmission (1.29; 1.11 to 1.46) and emergency (1.07; 1.02 to 1.13), for diagnoses of the nervous (1.94; 1.74 to 2.15), circulatory (1.24; 1.14 to 1.34) and respiratory (1.2; 1.03 to 1.37) systems and other factors influencing health status (1.92; 1.74 to 2.09).

CONCLUSIONS

The high relevance of episode change and other factors influencing health status revealed that a substantial part of excess demand for inpatient care was associated with discordant conditions often linked to frailty, decline in psychological health and social vulnerability. This suggests that multidisciplinary models of care that aim to manage discordant comorbidities and address psychosocial determinants of health, such as renal supportive care, may play an important role in reducing inpatient admissions in this population.
