Description of intervention(s) / exposure
Prevalent patients undergoing extended hours / home based therapy :
Haemodialysis (>6hour treatment at a frequency of alternate nightly or greater = >20hrs treatment/week) OR peritoneal dialysis (conventional ambulatory peritoneal dialysis or overnight automated peritoneal dialysis). Patients must be established on therapy for at least 3 months. Patients will be observed over one dialysis treatment and subsequent interdialytic period.
Intervention code [1] 289986 0
Not applicable
Comparator / control treatment
Standard conventional thrice weekly in-centre haemodialysis (<15hrs/week treatment time)
Control group
Active

Outcomes
Primary outcome [1] 292873 0
Systolic Hypertension as defined by SBP >160mmHg by brachial cuff measurement on the non-vascular access arm.
Timepoint [1] 292873 0
Assessed at incident treatment period through the Intra and Interdialytic timeframes. Intradialytic timepoints are pre & post dialysis, with hourly measures in-between. Interdialytic timepoints as assessed by ambulatory (brachial) monitoring at 30 minute daytime cycles and hourly overnight. Patients will be established on therapy for >3months at time of study. Patients will be observed over one dialysis treatment and subsequent interdialytic period (~44 hours)
Secondary outcome [1] 309848 0
Blood Pressure Variability as defined by standard deviation of the cumulative systolic pressure readings from noninvasive brachial cuff measures.
Timepoint [1] 309848 0
Assessed at incident treatment period through the Intra and Interdialytic timeframes. Intradialytic timepoints are pre & post dialysis, with hourly measures in-between. Interdialytic timepoints as assessed by ambulatory (brachial) monitoring at 30 minute daytime cycles and hourly overnight.Patients will be established on therapy for >3months at time of study. Patients will be observed over one dialysis treatment and subsequent interdialytic period (~44 hours)
