Inappropriate prescribing in patients with kidney disease: A rapid review of prevalence, associated clinical outcomes and impact of interventions. Basic Clin Pharmacol Toxicol 2024; 134:439-459. [PMID: 38348501 DOI: 10.1111/bcpt.13986] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/07/2023] [Revised: 01/11/2024] [Accepted: 01/17/2024] [Indexed: 03/16/2024]
Abstract
BACKGROUND The prevalence of patients with chronic kidney disease (CKD) and polypharmacy is increasing and has amplified the importance of examining inappropriate prescribing (IP) in CKD. This review focuses on the latest research regarding the prevalence of IP in CKD and the related adverse clinical effects and explores new interventions against IP. METHOD A literature search was performed using PubMed, EMBASE and the Cochrane Library searching articles published between June 2016 and March 2022. RESULTS Twenty-seven studies were included. An IP prevalence of 12.6% to 96% and 0.3% to 66% was reported in hospital and outpatient settings, respectively. In nonhospital settings, the prevalence of IP varied between 3.9% and 60%. IP was associated with higher risk of hospitalisation (HR 1.46, 95% CI 1.17-1.81), higher bleeding rate (HR 2.34, 95% CI 1.32 to 3.37) and higher risk of all-cause mortality (OR 1.07, 95% CI 1.02 to 1.13). Three studies reported the impact of interventions on IP. CONCLUSION This review highlights widespread IP in CKD patients across healthcare settings, with varying prevalence rates. IP is substantially linked to adverse outcomes in patients. While limited interventions show promise, urgent research is needed to develop effective strategies addressing IP and improving CKD patient care.

Estimating the population-level impacts of improved uptake of SGLT2 inhibitors in patients with chronic kidney disease: a cross-sectional observational study using routinely collected Australian primary care data. THE LANCET REGIONAL HEALTH. WESTERN PACIFIC 2024; 43:100988. [PMID: 38192747 PMCID: PMC10772282 DOI: 10.1016/j.lanwpc.2023.100988] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 10/27/2023] [Accepted: 11/28/2023] [Indexed: 01/10/2024]
Abstract
Background Sodium glucose co-transporter 2 (SGLT2) inhibitors reduce the risk of kidney failure and death in patients with chronic kidney disease (CKD) but are underused. We evaluated the number of patients with CKD in Australia that would be eligible for treatment and estimated the number of cardiorenal and kidney failure events that could be averted with improved uptake of SGLT2 inhibitors. Methods This cross-sectional observational study leveraged nationally representative primary care data from 392 Australian general practices (MedicineInsight) between 1 January 2020 and 31 December 2021. We identified patients that would have met inclusion criteria of key SGLT2 inhibitor trials and applied these data to age and sex-stratified estimates of CKD prevalence for the Australian population (using national census data), estimating the number of preventable events using trial event rates. Key outcomes included cardiorenal events (CKD progression, kidney failure, or death due to cardiovascular or kidney disease) and kidney failure. Findings In MedicineInsight, 44.2% of adults with CKD would have met CKD eligibility criteria for an SGLT2 inhibitor; baseline use was 4.1%. Applying these data to the Australian population, 230,246 patients with CKD would have been eligible for treatment with an SGLT2 inhibitor. Optimal implementation of SGLT2 inhibitors (75% uptake) could reduce cardiorenal and kidney failure events annually in Australia by 3644 (95% CI 3526-3764) and 1312 (95% CI 1242-1385), respectively. Interpretation Improved uptake of SGLT2 inhibitors for patients with CKD in Australia has the potential to prevent large numbers of patients experiencing CKD progression or dying due to cardiovascular or kidney disease. Identifying strategies to increase the uptake of SGLT2 inhibitors is critical to realising the population-level benefits of this drug class.

Abstract
Chronic kidney disease (CKD) is a persistent, progressive condition characterized by gradual decline of kidney functions leading to a range of health issues. This research used recent data from the Ministry of Public Health in Thailand and applied spatial regression and local indicators of spatial association (LISA) to examine the spatial associations with night-time light, Internet access and the local number of health personnel per population. Univariate Moran's I scatter plot for CKD in Thailand's provinces revealed a significant positive spatial autocorrelation with a value of 0.393. High-High (HH) CKD clusters were found to be predominantly located in the North, with Low-Low (LL) ones in the South. The LISA analysis identified one HH and one LL with regard to Internet access, 15 HH and five LL clusters related to night-time light and eight HH and five LL clusters associated with the number of health personnel in the area. Spatial regression unveiled significant and meaningful connections between various factors and CKD in Thailand. Night-time light displayed a positive association with CKD in both the spatial error model (SEM) and the spatial lag model (SLM), with coefficients of 3.356 and 2.999, respectively. Conversely, Internet access exhibited corresponding negative CKD associations with a SEM coefficient of - 0.035 and a SLM one of -0.039. Similarly, the health staff/population ratio also demonstrated negative associations with SEM and SLM, with coefficients of -0.033 and -0.068, respectively. SEM emerged as the most suitable spatial regression model with 54.8% according to R2. Also, the Akaike information criterion (AIC) test indicated a better performance for this model, resulting in 697.148 and 698.198 for SEM and SLM, respectively. These findings emphasize the complex interconnection between factors contributing to the prevalence of CKD in Thailand and suggest that socioeconomic and health service factors are significant contributing factors. Addressing this issue will necessitate concentrated efforts to enhance access to health services, especially in urban areas experiencing rapid economic growth.

[PMID: 37924060 PMCID: PMC10625205 DOI: 10.1186/s12962-023-00491-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/29/2023] [Accepted: 10/24/2023] [Indexed: 11/06/2023] Open
Abstract
BACKGROUND Chronic Kidney Disease (CKD) patients often require long-term care, and while Hemodialysis (HD) is the standard treatment, Comprehensive Conservative Care (CCC) is gaining popularity as an alternative. Economic evaluations comparing their cost-effectiveness are crucial. This study aims to perform a cost-utility analysis comparing HD and CCC using the EQ-5D-5L and ICECAP-O instruments to assessing healthcare interventions in CKD patients. METHODS This short-term economic evaluation involved 183 participants (105 HD, 76 CCC) and collected data on demographics, comorbidities, laboratory results, treatment costs, and HRQoL measured by ICECAP-O and EQ-5D-5L. Incremental Cost-Effectiveness Ratios (ICERs) and Net Monetary Benefit (NMB) were calculated separately for each instrument, and Probabilistic Sensitivity Analysis (PSA) assessed uncertainty. RESULTS CCC demonstrated significantly lower costs (mean difference $8,544.52) compared to HD. Both EQ-5D-5L and ICECAP-O indicated higher Quality-Adjusted Life Years (QALYs) for both groups, but the difference was not statistically significant (p > 0.05). CCC dominated HD in terms of HRQoL measures, with ICERs of -$141,742.67 (EQ-5D-5L) and -$4,272.26 (ICECAP-O). NMB was positive for CCC and negative for HD, highlighting its economic feasibility. CONCLUSION CCC proves a preferable and more cost-effective treatment option than HD for CKD patients aged 65 and above, regardless of the quality-of-life measure used for QALY calculations. Both EQ-5D-5L and ICECAP-O showed similar results in cost-utility analysis.

Abstract
PURPOSE To assess the relative cost-effectiveness of genomic testing compared with standard non-genomic diagnostic investigations in patients with suspected monogenic kidney disease from an Australian health care system perspective. METHODS Diagnostic and clinical information was used from a national cohort of 349 participants. Simulation modelling captured diagnostic, health, and economic outcomes during a time horizon from clinical presentation until 3 months post-test results based on the outcome of cost per additional diagnosis and lifetime horizon based on cost per quality-adjusted life-year (QALY) gained. RESULTS Genomic testing was Australian dollars (AU$) 1600 more costly per patient and led to an additional 27 diagnoses out of a 100 individuals tested, resulting in an incremental cost-effectiveness ratio of AU$5991 per additional diagnosis. Using a lifetime horizon, genomic testing resulted in an additional cost of AU$438 and 0.04 QALYs gained per individual compared with standard diagnostic investigations, corresponding to an incremental cost-effectiveness ratio of AU$10,823 per QALY gained. Sub-group analyses identified that the results were largely driven by the cost-effectiveness in glomerular diseases. CONCLUSION Based on established or expected thresholds of cost-effectiveness, our evidence suggests that genomic testing is very likely to be cost saving for individuals with suspected glomerular diseases, whereas no evidence of cost-effectiveness was found for non-glomerular diseases.

Abstract
INTRODUCTION This study aimed to identify opportunities for clinical decision support targeting medication safety in remote primary care, by investigating the relationship between clinical workflows, health system priorities, cognitive tasks, and reasoning processes in the context of medicines used in people with chronic kidney disease (CKD). METHODS This qualitative study involved one-on-one, semistructured interviews. The participants were healthcare professionals employed in a clinical or managerial capacity with clinical work experience in a remote health setting for at least 1 year. RESULTS Twenty-five clinicians were interviewed. Of these, four were rural medical practitioners, nine were remote area nurses, eight were Aboriginal health practitioners, and four were pharmacists. Four major themes were identified from the interviews: (1) the need for a clinical decision support system to support a sustainable remote health workforce, as clinicians were "constantly stretched" and problems may "fall through the cracks"; (2) reliance on digital health technologies, as medical staff are often not physically available and clinicians-on-duty usually "flick an email and give a call so that I can actually talk it through to our GP"; (3) knowledge gaps, as "it takes a lot of mental space" to know each patient's renal function and their medication history, and clinicians believe "mistakes can be made"; and (4) multiple risk factors impacting CKD management, including clinical, social and behavioural determinants. CONCLUSIONS The high prevalence of CKD and reliance on digital health systems in remote primary health settings can make a clinical decision support system valuable for supporting clinicians who may not have extensive experience in managing medicines for people with CKD.

Abstract
OBJECTIVE Concerns have been raised over the appropriateness of dosing of direct-acting oral anticoagulants (DOACs) in clinical practice. We investigated this issue in patients who were initiated on a DOAC in Australian general practices. METHODS This was a retrospective study among patients newly diagnosed with atrial fibrillation (AF) who were prescribed DOACs, using data obtained from 417 general practice sites across Australia over 8 years (2011-2019). Direct-acting oral anticoagulant dosing was compared with published recommendations, in relation to age and kidney function. RESULTS A total of 11,251 patients (mean age, 72.8 y; 46.8% female) newly diagnosed with AF were prescribed a DOAC. Of these, 2667 patients (23.7%) had a recorded prescription of a potentially inappropriate DOAC dosage, of whom 2304 (86.4%) and 283 (10.6%) were prescribed lower and higher than the recommended dosage, respectively. The remaining 80 patients (3.0%) were initiated on DOACs when contraindicated based on renal function. Overall, the proportion of patients who seemed to be initiated on a potentially inappropriate DOAC dose decreased from 38.3% (95% confidence interval, 26.1%-51.8%) in 2012 to 22.7% (95% confidence interval, 19.8%-26.0%; P < 0.001) in 2019. By 2019, 19.4%, 20.3%, and 9.3% of the patients with a recorded prescription of apixaban, rivaroxaban, and dabigatran, respectively, received a lower-than-guideline-recommended dose. The patients were more likely to be prescribed a potentially inappropriate dosage if they were elderly with multiple comorbidities. CONCLUSIONS Potential inappropriate DOAC dosing is a problem in the prevention of stroke associated with AF. Nearly 1 in 5 patients received a lower-than-guideline-recommended dose, indicating a need for strategies to raise awareness among prescribers.

Abstract
BACKGROUND We aimed to compare renal function changes in patients with atrial fibrillation (AF) prescribed different oral anticoagulants (OACs). RESEARCH DESIGN AND METHODS We performed a retrospective analysis of Australian national primary care data. A total of 12,562 patients with AF and initiated OAC between 1 Jan 2013 and 31 Dec 2017 were included. Inverse probability of treatment weighting was used for balancing baseline characteristics and the risks of decline in estimated glomerular filtration rate (eGFR) in patients prescribed each OAC were compared using Cox proportional hazards regression model. RESULTS Compared with warfarin, prescribing of direct-acting oral anticoagulants (DOACs) was associated with a lower risk of renal function decline per 1000 person-years: hazard ratio (HR) 0.75, 95% confidence interval (CI) 0.68-0.81, p<0.001 for ≥30% decline in eGFR; HR 0.28, 95% CI 0.20-0.41, p<0.001 for eGFR decline to ≤30 mL/min/1.73m2; and HR 0.45, 95% CI 0.35-0.58, p<0.001 for serum creatinine doubling. Compared with dabigatran, rivaroxaban use had a significantly lowered risk of decline in eGFR to ≤30 mL/min/1.73m2 (HR 0.29, 95% CI 0.13-0.66, p=0.003) and risk of doubling of serum creatinine (HR 0.62, 95% CI 0.40-0.95, p=0.030). CONCLUSIONS The risk of renal function decline appeared to be lower in patients prescribed DOACs versus warfarin.

Abstract
AIM The aim was to describe vascular risk factors in Australian adults with diabetes attending an Indigenous primary care nurse-led diabetes clinic. DESIGN This was a cross-sectional descriptive single-site study. METHODS Vascular risk factor data were extracted from the electronic health records of participants in the nurse-led integrated Diabetes Education and Eye disease Screening (iDEES) study at a regional Victorian Indigenous primary health-care clinic between January 2018 and March 2020. RESULTS Of 172 eligible adults, 135 (79%) provided data. Median (IQR) age was 56 (46-67) years; 89% were Indigenous; 95% had Type 2 diabetes of median (IQR) duration of 6 (2-12) years and 48 (36%) were male. Median HbA1c, blood pressure, cholesterol (total; LDL and HDL), triglycerides, eGFR, CRP and BMI were 8.0% (64 mmol/mol), 127/78 mm Hg, 4.2; 1.9; 1.1 mmol/L, 2.3 mmol/L, 89 ml/min/1.73 m2 , 7.0 mg/L and 32.4 kg/m2 . Of nine clinical risk factors, the median (IQR) number of risk factors at target was 4 (3-5) for women and 3 (2-5) for men, pχ2 = 0.563. Clinical targets for BMI, HbA1c, blood pressure, triglycerides, total cholesterol, LDL cholesterol, urine albumin: creatinine ratio, HDL cholesterol and smoking were met by 14%, 34%, 38%, 39%, 44%, 52%, 54%, 62% and 64%, respectively. CONCLUSION A nurse-led model of integrated clinical risk factor assessment and diabetes education identified suboptimal levels of clinical risk factor control for avoiding diabetes chronic complications amongst Australian adults with diabetes in an Indigenous primary care setting. IMPACT A nurse-led model of diabetes care integrating clinical risk factor assessment into a diabetes education service is achievable. Understanding by stakeholders, including people with diabetes, their clinicians and health services, of the importance of regular monitoring of risk factors impacting diabetes complications is important. The novel nurse-managed iDEES primary-care model of care can assist. TRIAL REGISTRATION This study was registered with the Australian New Zealand Clinical Trials Registry (ACTRN12618001204235).

[PMID: 35109801 PMCID: PMC8812263 DOI: 10.1186/s12879-022-07039-5] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/24/2021] [Accepted: 12/14/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND While there has been a recent epidemiological and clinical focus on the interaction between diabetes and tuberculosis, the interaction between chronic kidney disease and tuberculosis has been less studied. In particular, little is known of the effect of eGFR levels well above that seen in end stage kidney disease on mortality. METHODS We conducted a retrospective cohort study of 653 adults from a large Australian hospital network, using data from a state-wide registry of reported tuberculosis cases between 2010 and 2018, with ascertainment of diabetes status and renal function data from hospital medical records and laboratory data. Cox proportional hazards regression models were used to calculate hazard ratios for all-cause mortality associated with categories of chronic kidney disease in adults with tuberculosis disease. RESULTS Total number of deaths was 25 (3.8%). Compared to tuberculosis cases with eGFR ≥ 60 ml/min, all-cause mortality was higher for those with chronic kidney disease from an eGFR level of 45 ml/min. The association was independent of sex, age and diabetes status with adjusted hazard ratio of 4.6 (95% CI: 1.5, 14.4) for eGFR 30-44 ml/min and 8.3 (95% CI: 2.9, 23.7) for eGFR < 30 ml/min. CONCLUSIONS Our results suggest a notably increased risk of all-cause mortality even in those with more moderate degrees of renal impairment, in a low tuberculosis prevalence setting. The impact of these findings on a population basis are at least as significant as that found with diabetes and warrant further investigation in populations with higher tuberculosis prevalence.

Abstract
Objective To report (using linked laboratory data) the incidence, prevalence and geographic variation of chronic kidney disease (CKD) across the whole island population of Tasmania, Australia. Methods A retrospective cohort study (the Tasmanian Chronic Kidney Disease study (CKD.TASlink)) using linked data from five health and two pathology datasets from the island state of Tasmania, Australia between 1/1/2004 and 31/12/2017. We used data on 460,737 Tasmanian adults (aged 18 years and older, representing 86.8% of the state's population) who had a serum creatinine measured during the study period. We defined CKD as per Kidney Disease Outcomes Quality Initiative, requiring two measures of estimated glomerular filtration rate (eGFR) <60 mL/min/1.73m2, at least three months apart. Kidney replacement therapy (KRT) included dialysis or kidney transplantation. Results We identified 56,438 Tasmanians with CKD during the study period, equating to an age-standardised annual incidence of 1.0% and a prevalence of 6.5%. These figures were higher in women, older Tasmanians and people living in the North-West region of Tasmania. Testing for urinary albumin:creatinine ratio is increasing, with 28.5% of women and 30.8% of men with stage 3 CKD having both an eGFR and uACR in 2017. Use of KRT was consistently seen in >65% of Tasmanians with eGFR <15 mL/min/1.73m2. Conclusion There is geographic and gender variation in the incidence and prevalence of CKD, but it is reassuring to see that the majority of people with end-stage kidney failure are actually receiving treatment with dialysis or transplantation.

Abstract
AIM To examine the change in stroke risk over time and determine the proportion of patients with atrial fibrillation (AF) who were initiated on an oral anticoagulant (OAC) as their stroke risk increased from low/moderate to high, using the Australian general practice data set, MedicineInsight. METHODS A total of 2296 patients diagnosed with AF between 1 January 2007 and 31 December 2008, aged 18 years or older and not initiated on an OAC before 2009, were included. We assessed the change in stroke risk and the proportion of patients who had a recorded prescription of an OAC, each year from 1 January 2009 to 31 December 2018. RESULTS At baseline, 23.9%, 22.9% and 53.2% were categorised as being at low (score = 0), moderate (score = 1) and high stroke risk (score ≥ 2), respectively, using the sexless CHA2 DS2 -VASc (CHA2 DS2 -VA) score. Overall, the CHA2 DS2 -VA score increased by a mean of 1.34 (95% confidence interval, 1.29-1.39) points over the study period. Nearly two-thirds of patients (65%, 412/632) whose stroke risk changed from baseline low/moderate to high were subsequently prescribed an OAC. The median (interquartile range) lag time from becoming high stroke risk to having OAC initiation was 2 (5) years. CONCLUSIONS Nearly one-third of patients reclassified as being at high risk of stroke during the study period were not prescribed OAC therapy. Furthermore, the delay in OAC initiation following classification as being at high risk was a median of 2 years, suggesting that more frequent stroke reassessment is needed.

Abstract
BACKGROUND We investigated factors that influenced oral anticoagulant (OAC) initiation and choice in Australian general practice patients newly diagnosed with AF. METHODS Using an Australian nationally representative general practice dataset, MedicineInsight, we identified patients newly diagnosed with AF between January 2009 and April 2019. Logistic regression analyses were used to examine factors associated with OAC initiation and choice. RESULTS A total of 63 212 patients with AF (53.7% males, mean age 72.4 years) were identified. Nearly two-thirds of these patients (40 854 [64.6%]) were initiated on an OAC, at a median time of 6 days after the documented diagnosis date. The proportion of patients who were initiated an OAC increased from 44.8% in 2009 to 72.2% in 2019 (P < .001). High risk of stroke (CHA2 DS2 -VASc, adjusted odds ratio (AOR), 4.39 [95% CI, 3.99-4.83]), low risk of bleeding (ORBIT, AOR, 1.87 [95% CI, 1.72-2.03]), not having a recorded history of dementia (AOR, 1.81 [95% CI, 1.65-1.98]) and male sex (AOR, 1.29 [95% CI, 1.22-1.35]) were independently associated with OAC initiation. Direct-acting oral anticoagulant (DOAC) use increased from 11.9% in 2011 to 94.0% of all OAC initiations in April 2019 (P < .001). CONCLUSIONS The proportion of newly diagnosed patients with AF initiated on OAC increased markedly following the introduction of the DOACs. Of those initiated, 9 in 10 were receiving a DOAC at the end of the study period. There is potential underuse in women and individuals with dementia.

Abstract
Objective: Appropriate use of oral anticoagulants (OACs) reduces the risk of stroke in patients with atrial fibrillation (AF). The study characterized the prescribing of OACs in people with AF in the Australian primary care setting over 10 years. Design: Retrospective population study. Setting and Participants: We performed 10 sequential cross-sectional analyses of patients with a recorded diagnosis of AF between 2009 and 2018 using national general practice data. The proportion of patients with AF who were prescribed an OAC based on their stroke risk was examined. Primary and secondary outcomes: The primary outcome was the proportion of high stroke risk patients who were prescribed an OAC over a decade. The secondary outcome was variation in OAC prescribing among general practices. Results: The sample size of patients with AF ranged from 9,874 in 2009 to 41,751 in 2018. The proportion who were prescribed an OAC increased from 39.5% (95% CI 38.6–40.5%) in 2009 to 52.0% (95% CI 51.5–52.4%) in 2018 (p for trend < 0.001). During this time, the proportion of patients with AF and high stroke risk who were prescribed an OAC rose from 41.7% (95% CI 40.7–42.8%) to 55.2% (95% CI 54.7–55.8%; p for trend < 0.001) with the direct-acting oral anticoagulants accounting for over three-quarters of usage by 2018. There was substantial variation in OAC prescribing between general practices. In 2018, the proportion of moderate to high stroke risk patients who were prescribed an OAC was 38.6% (95% CI 37.2–40.1%) in the lowest practice site quintiles and 65.6% (95% CI 64.5–66.7%) in the highest practice site quintiles. Conclusions: Over the 10 years, OAC prescribing in high stroke risk patients with AF increased by one-third. There was considerable variation in OAC prescribing between general practices.

Abstract
INTRODUCTION Hypertension is mostly managed in primary care. This study investigated the prevalence of diagnosed hypertension in Australian general practice and whether hypertension control is influenced by sociodemographic characteristics, duration since diagnosis or prescription of antihypertensive medications. METHODS Cross-sectional study using a large national database of electronic medical records of patients attending general practice in 2017 (MedicineInsight). RESULTS Of 1.2 million 'regular' patients (one or more consultations per year in every year from 2015 to 2017), 39.8% had a diagnosis of hypertension (95% confidence interval 38.7-40.9). Of these, 85.3% had their blood pressure (BP) recorded in 2017, and 54.9% (95% confidence interval 54.2-55.5) had controlled hypertension (<140/90 mmHg). BP control was lower in females (54.1%) compared with males (55.7%) and in the oldest age group (52.0%), with no differences by socioeconomic status. Hypertension control was lower among 'regular' patients recently diagnosed (6-12 months = 48.6% controlled) relative to those more than 12 months since diagnosis (1-2 years = 53.6%; 3-5 years 55.5%; >5 years = 55.0%). Among recently diagnosed 'regular' patients, 59.2% had no record of being prescribed antihypertensive therapy in the last 6 months of the study, of which 44.3% had controlled hypertension. For those diagnosed more than 5 years ago, 37.4% had no record of being prescribed antihypertensive patients, and 56% had normal BP levels. CONCLUSION Although the prevalence of hypertension varied by socidemographics, there were no differences in BP assessment or control by socioeconomic status. Hypertension control remains a challenge in primary care, and electronic medical records provide an opportunity to assess hypertension management.

Abstract
BACKGROUND Chronic kidney disease (CKD) affects drug elimination and patients with CKD require appropriate adjustment of renally cleared medications to ensure safe and effective pharmacotherapy. The main objective of this study was to determine the extent of potentially inappropriate prescribing (PIP; defined as the use of a contraindicated medication or inappropriately high dose according to the kidney function) of renally-cleared medications commonly prescribed in Australian primary care, based on two measures of kidney function. A secondary aim was to assess agreement between the two measures. METHODS Retrospective analysis of routinely collected de-identified Australian general practice patient data (NPS MedicineWise MedicineInsight from January 1, 2013, to June 1, 2016; collected from 329 general practices). All adults (aged ≥18 years) with CKD presenting to general practices across Australia were included in the analysis. Patients were considered to have CKD if they had two or more estimated glomerular filtration rate (eGFR) recorded values < 60 mL/min/1.73m2, and/or two urinary albumin/creatinine ratios ≥3.5 mg/mmol in females (≥2.5 mg/mmol in males) at least 90 days apart. PIP was assessed for 49 commonly prescribed medications using the Cockcroft-Gault (CG) equation/eGFR as per the instructions in the Australian Medicines Handbook. RESULTS A total of 48,731 patients met the Kidney Health Australia (KHA) definition for CKD and had prescriptions recorded within 90 days of measuring serum creatinine (SCr)/estimated glomerular filtration rate (eGFR). Overall, 28,729 patients were prescribed one or more of the 49 medications of interest. Approximately 35% (n = 9926) of these patients had at least one PIP based on either the Cockcroft-Gault (CG) equation or eGFR (CKD-EPI; CKD-Epidemiology Collaboration Equation). There was good agreement between CG and eGFR while determining the appropriateness of medications, with approximately 97% of the medications classified as appropriate by eGFR also being considered appropriate by the CG equation. CONCLUSION This study highlights that PIP commonly occurs in primary care patients with CKD and the need for further research to understand why and how this can be minimised. The findings also show that the eGFR provides clinicians a potential alternative to the CG formula when estimating kidney function to guide drug appropriateness and dosing.

Abstract
Background: Australian patients with chronic kidney disease (CKD) are routinely managed in general practices with multiple medications. However, no nationally representative study has evaluated the quality of prescribing in these patients. The objective of this study was to examine the quality of prescribing in patients with CKD using nationally representative primary care data obtained from the NPS MedicineWise’s dataset, MedicineInsight. Methods: A cross-sectional analysis of general practice data for patients aged 18 years or older with CKD was performed from 1 February 2016 to 1 June 2016. The study examined the proportion of patients with CKD who met a set of 16 published indicators in two categories: (1) potentially appropriate prescribing of antihypertensives, renin-angiotensin system (RAS) inhibitors, phosphate binders, and statins; and (2) potentially inappropriate prescribing of nephrotoxic medications, such as non-steroidal anti-inflammatory drugs (NSAIDs), at least two RAS inhibitors, triple therapy (an NSAID, a RAS inhibitor and a diuretic), high-dose digoxin, and metformin. The proportion of patients meeting each quality indicator was stratified using clinical and demographic characteristics. Results: A total of 44,259 patients (24,165 (54.6%) female; 25,562 (57.8%) estimated glomerular filtration (eGFR) 45–59 mL/1.73 m2) with CKD stages 3–5 were included. Nearly one-third of patients had diabetes and were more likely to have their blood pressure and albumin-to-creatinine ratio monitored than those without diabetes. Potentially appropriate prescribing of antihypertensives was achieved in 79.9% of hypertensive patients with CKD stages 4–5. The prescribing indicators for RAS inhibitors in patients with microalbuminuria and diabetes and in patients with macroalbuminuria were achieved in 69.9% and 62.3% of patients, respectively. Only 40.8% of patients with CKD and aged between 50 and 65 years were prescribed statin therapy. The prescribing of a RAS inhibitor plus a diuretic was less commonly achieved, with the indicator met in 20.6% for patients with microalbuminuria and diabetes and 20.4% for patients with macroalbuminuria. Potentially inappropriate prescribing of NSAIDs, metformin, and at least two RAS inhibitors were apparent in 14.3%, 14.1%, and 7.6%, respectively. Potentially inappropriate prescribing tended to be more likely in patients aged ≥65 years, living in regional or remote areas, or with socio-economic indexes for areas (SEIFA) score ≤ 3. Conclusions: We identified areas for possible improvement in the prescribing of RAS inhibitors and statins, as well as deprescribing of NSAIDs and metformin in Australian general practice patients with CKD.

BACKGROUND There is international interest in whether improved primary care, in particular for patients with chronic or complex conditions, can lead to decreased use of health resources and whether financial incentives help achieve this goal. This trial (EQuIP-GP) will investigate whether a funding model based upon targeted, continuous quality incentive payments for Australian general practices increases relational continuity of care, and lessens health-service utilisation, for high-risk patients and children. METHODS We will use a mixed methods approach incorporating a two-arm pragmatic cluster randomised control trial with nested qualitative case studies. We aim to recruit 36 general practices from Practice-Based Research Networks (PBRN) covering urban and regional areas of Australia, randomised into intervention and control groups. Control practices will provide usual care while intervention practices will be supported to implement a new service model incorporating incentives for relational continuity and timely access to appointments. Patients will comprise three groups: older (over 65 years); 18-65 years with chronic and/or complex conditions; and those aged less than 16 years with increased risk of hospitalisation. The funding model includes financial incentives to general practitioners (GPs) for providing longer consultations, same day access and timely follow-up after hospitalisation to enrolled patients. The payments are proportional to expected health system savings associated with improved quality of GP care. An outreach facilitator will work with practices to help incorporate the incentive model into usual work. The main outcome measure is relational continuity of care (Primary Care Assessment Tool short-form survey), with secondary outcomes including health-related quality of life and health service use (hospitalisations, emergency presentations, GP and specialist services in the community, medicine prescriptions and targeted pathology and imaging ordering). Outcomes will be initially evaluated over a period of 12 months, with ongoing data collection for 5 years. DISCUSSION The trial will provide robust evidence on a novel approach to providing continuous incentives for improving quality of general practice care, which can be compared to block payment incentives awarded at target quality levels of pay-for-performance, both within Australia and also internationally.
