Article Abstract
Aim: The Australian and New Zealand Society of Nephrology (ANZSN) established a quality indicator (QI) program to measure performance and reduce variation of nephrology care. This program relies on registry data from the Australia and New Zealand Dialysis and Transplant Registry (ANZDATA). ANZDATA also conducts surveys to ascertain more granular characteristics of participating nephrology units to better understand variation in practice. This study assessed ANZDATA and nephrology unit surveys to determine patient- and centre-level factors that may account for variation in dialysis access QIs.
Methods: Dialysis access QIs were evaluated over a 5-year period using ANZDATA (2016-2020). Patient characteristics were derived from the same period and dataset. Centre characteristics were determined from the 2020-unit binational survey. Statistical analysis involved multivariable regression with fixed effects for patient- and centre-characteristics and a random effect by centre.
Results: Wide variation was seen across dialysis access QIs. Using multivariable regression, patient-level characteristics associated with definitive dialysis access at commencement of dialysis included male gender and body mass index decreasing from 30 kg/m. Centres with a home haemodialysis nurse and a 'peritoneal dialysis (PD) first policy' were associated with higher rates of definitive dialysis access. There was also a progressive relationship with the number of full-time equivalent (FTE) medical staff if the unit already had an FTE greater than 10. Inclusion of centre-level variables reduced the variance in the model by 68%.
Conclusion: This study demonstrates certain patient- and centre-level characteristics are associated with definitive dialysis access at the commencement of dialysis in Australia and New Zealand. Interventional trials for PD first programmes and different models of care for vascular access are needed.

Surgical outcomes following telehealth preoperative evaluation in elective cardiac surgery.

Objective: Telehealth preoperative evaluations have been shown to improve access to care, reduce appointment cancellations, and support efficient procedural planning across multiple surgical subspecialties. However, few studies have assessed the safety and efficacy in patients undergoing elective cardiac surgery.
Methods: We conducted a retrospective multi-institutional cohort study comparing procedural and postoperative outcomes for patients who had telehealth versus in-person preoperative evaluations for elective cardiac surgery between March 1, 2020, and March 1, 2021.

The rate of end-stage kidney disease (ESKD) is steadily rising in the United States, and older adults (ie, 65 years and older) represent the fastest-growing segment in need of hemodialysis. This demographic shift presents unique challenges due to age-related comorbidities, frailty, and increased procedural risks. Despite these challenges, there is limited guidance for risk stratification and management of renal replacement therapy in older patients with ESKD.

Background: Delayed discharge among older patients presents a major challenge for the efficiency of health service delivery. Prolonged hospitalizations limit bed turnover, increase costs, and reduce the availability of hospital resources. In Japan, older adults must undergo a formal care needs certification process to access public long-term care (LTC) services.

For many years, the vascular access guidelines recommended placement of arteriovenous fistulas (AVFs) in preference to arteriovenous grafts (AVGs) because AVFs had superior long-term patency, required fewer interventions to maintain patency, and were associated with lower costs of vascular access management. However, subsequent research has questioned the "Fistula First strategy" (placing an AVF whenever the vascular anatomy is suitable). First, AVF non-maturation is substantial (30-40%), and even higher among women, older patients and those with peripheral vascular disease.
