Adding specialized clinics for remote-dwellers with chronic kidney disease: a cost-utility analysis.

ABSTRACT:

Background and objectives

This study aimed to determine whether opening a new clinic in a remote region would be a cost-effective means of improving care for remote-dwellers with CKD.

Design, setting, participants, & measurements

This study is a cost-utility analysis from a public payer's perspective over a lifetime horizon, using administrative data from a large cohort of adults with stage 3b-4 CKD in Alberta, Canada. The association between the distance from each simulated patient's residence and the practice location of the closest nephrologist and clinical outcomes (quality of care, hospitalization, dialysis, and death) were examined. A Markov 6-month cycle economic decision model was analyzed; estimates of the effect of a new clinic were based on the association between residence location, resource use, and outcomes. Costs are reported in 2009 Canadian dollars.

Results

The costs for equipping and operating a clinic for 321 remote-dwelling patients were estimated at $25,000 and $250,000/yr, respectively. The incremental cost-utility ratios (ICURs) ranged from $4000 to $8000/quality-adjusted life-year under most scenarios. However, if reducing distance to nephrologist care does not alter mortality or hospitalization among remote-dwellers, the cost-effectiveness becomes less attractive. All other one-way sensitivity analyses had negligible effects on the ICUR.

Conclusions

Given the low costs of equipping and operating new clinics, and the very attractive ICUR relative to other currently funded interventions, establishing new clinics for remote-dwellers could play an important role in efficiently improving outcomes for patients with CKD. High-quality controlled studies are required to confirm this hypothesis.

Project description:Background:Health systems are under pressure to deliver more effective care without expansion of resources. This is particularly pertinent to diseases like chronic kidney disease (CKD) that are exacting substantial financial burden to many health systems. The aim of this study is to systematically review the Cost Utility Analysis (CUA) evidence generated across interventions for CKD patients undergoing kidney transplant (KT). Methods:A systemic review of CUA on the interventions for CKD patients undergoing KT was carried out using a search of the MEDLINE, CINAHL, EMBASE, PsycINFO and NHS-EED. The CHEERS checklist was used as a set of good practice criteria in determining the reporting quality of the economic evaluation. Quality of the data used to inform model parameters was determined using the modified hierarchies of data sources. Results:A total of 330 articles identified, 16 met the inclusion criteria. Almost all (n?=?15) the studies were from high income countries. Out of the 24 characteristics assessed in the CHEERS checklist, more than 80% of the selected studies reported 14 of the characteristics. Reporting of the CUA were characterized by lack of transparency of model assumptions, narrow economic perspective and incomplete assessment of the effect of uncertainty in the model parameters on the results. The data used for the economic model were satisfactory quality. The authors of 13 studies reported the intervention as cost saving and improving quality of life, whereas three studies were cost increasing and improving quality of life. In addition to the baseline analysis, sensitivity analysis was performed in all the evaluations except one. Transplanting certain high-risk donor kidneys (high risk of HIV and Hepatitis-C infected kidneys, HLA mismatched kidneys, high Kidney Donor Profile Index) and a payment to living donors, were found to be cost-effective. Conclusions:The quality of economic evaluations reviewed in this paper were assessed to be satisfactory. Implementation of these strategies will significantly impact current systems of KT and require a systematic implementation plan and coordinated efforts from relevant stakeholders.

Project description:ImportanceThe self-reported frequency of adding salt to foods could reflect a person's long-term salt taste preference, and salt intake has been associated with increased risk of cardiovascular diseases (CVD). Whether self-reported adding of salt to foods is associated with increased risk of chronic kidney disease (CKD) remains unknown.ObjectiveTo prospectively examine the association of self-reported frequency of adding salt to foods with incident CKD risk in a general population of adults.Design, setting, and participantsThis population-based cohort study evaluated UK Biobank participants aged 37 to 73 years who were free of CKD at baseline. Participants were enrolled from 2006 to 2010 and prospectively followed up for disease diagnosis. Data were analyzed from October 2022 to April 2023.ExposureSelf-reported frequency of adding salt to foods, categorized into never or rarely, sometimes, usually, and always.Main outcome and measureIncident CKD cases were defined by diagnostic codes. Hazard ratios (HRs) and 95% CIs were calculated by using Cox proportional hazards models. Models were adjusted for several potential confounders including age, sex, race and ethnicity, Townsend Deprivation Index, estimated glomerular filtration rate (eGFR), body mass index, (BMI), smoking status, alcohol drinking status, regular physical activity, high cholesterol, diabetes, CVD, hypertension, infectious disease, immune disease, and nephrotoxic drugs use at baseline.ResultsWithin a cohort of 465 288 individuals (mean [SD] age 56.32 [8.08] years; 255 102 female participants [54.83%]; 210 186 male participants [45.17%]), participants with higher self-reported frequency of adding salt to foods were more likely to have a higher BMI, higher Townsend Deprivation Index score, and diminished baseline eGFR compared with those who reported a lower frequency of adding salt to foods. Participants who added salt to their foods were also more likely than those who did not add salt to their foods to be current smokers and have diabetes or CVD at baseline. During a median (IQR) follow-up of 11.8 (1.4) years, 22 031 incident events of CKD were documented. Higher self-reported frequency of adding salt to foods was significantly associated with a higher CKD risk after adjustment for covariates. Compared with those who reported never or rarely adding salt to foods, those who reported sometimes adding salt to food (adjusted HR [aHR], 1.04; 95% CI, 1.00-1.07), those who reported usually adding salt to food (aHR, 1.07; 95% CI, 1.02-1.11), and those who reported always adding salt to food (aHR, 1.11; 95% CI, 1.05-1.18) had an increased risk of CKD (P for trend < .001). In addition, eGFR, BMI, and physical activity significantly modified the associations, which were more pronounced among participants with a higher eGFR, lower BMI, or lower level of physical activity.Conclusions and relevanceIn this cohort study of 465 288 individuals, a higher self-reported frequency of adding salt to foods was associated with a higher risk of CKD in the general population. These findings suggest that reducing the frequency of adding salt to foods at the table might be a valuable strategy to lower CKD risk in the general population.

Project description:BACKGROUND:Chronic obstructive pulmonary disease (COPD) is one of the main reasons for healthcare appointments and use of healthcare resources. In recent years, clinics specializing in COPD have been developed to offer improved care and optimization of recourses for patients with high complexity and frequent decompensations. However, little is known about the clinical practice in this clinical model specializing in COPD. The objectives of this study were to assess the prevalence, characteristics of specialized COPD outpatient respiratory clinics and to evaluate clinical practice in this healthcare model. METHODS:EPOCONSUL is a Spanish nationwide, observational, cross-sectional, clinical audit with prospective case recruitment including the clinical records for 4508 COPD cases from outpatient respiratory clinics over a 12-month period (May 2014-May 2015). The study evaluated clinical practice in 2378 cases from 28 hospitals with both general and specialized COPD outpatient respiratory clinics. RESULTS:Only 28 (47.5%) centers had an outpatient clinic specializing in COPD, which was characterized by longer patient visits and a higher prevalence of written protocols compared to a general clinic. Patients treated in a specialized clinic had greater obstruction severity, a higher degree of dyspnea and also suffered from more comorbidities. The majority of patients at both types of clinic were classified as high risk (81.1% versus 83%, p = 0.384) according to GesEPOC criteria. Clinical control of COPD was more frequent at specialized clinics, with significant differences in non-severe patients (70.5% versus 56.1%, p < 0.001). Testing was done more frequently in specialized clinics, with better adherence to good clinical practice recommendations. CONCLUSION:A specialized COPD outpatient clinic is a healthcare model found in few pulmonology departments that treats more severe patients and those with increased comorbidities. The COPD patients treated in a specialized clinic had a better clinical control, as defined by impact and clinical stability. It is a healthcare model to offer improved care with a higher degree of adherence to guidelines.

Project description:BackgroundChronic kidney disease (CKD) clinics across Canada provide tailored care for patients with CKD with an aim to slow progression and prevent complications. These clinics provide CKD self-management resources; however, there is limited information about what resources are being used by clinics. We undertook a survey of CKD clinics across Canada to identify self-management resources for adults aged 18 years and over with CKD categories 1 to 5 and not requiring dialysis or transplant.ObjectiveTo identify and collate self-management resources (eg, strategies, tools, educational materials) used by CKD clinics across Canada for adults with CKD (categories 1 to 5, not requiring kidney replacement therapy).DesignSelf-administered, semistructured electronic survey.Setting participantsCanadian CKD clinics with previously identified contact information.Methods and measurementsWe contacted 57 CKD English-speaking clinics and invited them to complete an online survey. The survey was available from October 2016 to January 2017 and consisted of 17 questions regarding the use and attributes of self-management resources including topic, delivery format, provider, target population, where the intervention was provided, and resource languages.ResultsForty-four clinics (77%) completed the survey. The most common topic was modality education provided in print format, by nurses. The most frequently used resource was the Kidney Foundation of Canada (KFOC) Living With Kidney Disease manual. We also identified that the majority of resources were available in English, targeting both patients and caregivers in the outpatient setting.LimitationsOur survey included Canadian adult CKD clinics, which may not be generalizability to other settings, such as care of people with CKD in primary care.ConclusionsAdult CKD clinics across Canada provide some similar resources, but also provide many different self-management resources. Even though some of the same resources were used by multiple clinics, the way they were provided them (ie, provider, location, delivery format) varied by the individual clinics. Knowledge of self-management resources currently provided in CKD clinics, along with synthesis of the literature and patient preferred self-management strategies, will inform the design and development of a novel self-management intervention that is patient-centric and adheres to the principles of self-management.

Project description:BackgroundThe successful implementation of interventions targeted to improve kidney health requires early identification of CKD which involves screening at-risk populations as well as recognizing CKD. We aim to determine CKD screening and recognition rates, factors associated with these rates, and evaluate the effect of CKD awareness on delivery of care.MethodsA retrospective cohort study of veterans enrolled with Veterans Integrated Service Network 17 who had hypertension (HTN) and/or diabetes (DM) and were seen at least twice in primary care clinics within 18 months. The final cohort of 270,170 patients (52% HTN, 5% DM, and 44% both) was examined for serum creatinine/eGFR, urine protein/albumin, International Classification of Diseases (ICD) codes for CKD, and nephrology referral. CKD was defined as eGFR <60 ml/min per 1.73 m2 and/or urine albumin-creatinine ratio (uACR) >30 mg/g at least twice 90 days apart. Clinical covariates, HTN control, and prescription rates of renal prudent medications and nonsteroidal anti-inflammatory drugs (NSAIDs) were assessed.ResultsOverall, 254,831 (94%) patients had either eGFR, urine protein/albumin, or both. However, screening for protein/albuminuria was low (56%), particularly in patients with isolated HTN (35%). Of 254,831 patients, 92,900 (36%) had laboratory evidence of CKD and, of these, 40,586 (44%) were recognized to have CKD by ICD code and/or nephrology referral. CKD due to presence of uACR criteria alone had the lowest recognition (19%) as compared with CKD due to eGFR criteria (44%) or both (67%). Frequency of emergency room visits, hospitalization, and cardiac and endovascular procedures requiring contrast had the highest odds and races other than white had the lower odds of screening. In contrast, CKD recognition was high in races other than white and increased with worsening eGFR and increasing uACR. In screened and recognized CKD, prescription was higher for angiotensin inhibitors, statins, and diuretics, and was lower for NSAIDs.ConclusionsAlthough overall CKD screening rate was high, screening of protein/albuminuria in isolated HTN and overall recognition of CKD was low in at-risk veterans. Increased recognition was associated with a favorable prescription rate for renal prudent medications.
