Description of intervention(s) / exposure
POC-PDEE will utilise different methodologies to establish the safety, efficacy and usability of the Ellen Medical - Point of Care (EM-POC) peritoneal dialysis (PD) system with Australian dialysis patients. This study comprises three inter-linked components: (1) a series of human factors usability assessments, (2) a shadow study testing the reliability of the chemical composition and sterility of PD fluid produced by the EM-POC system when used by dialysis patients or their carers independently at the point-of-care and (3) semi-structured interviews to assess patient perspectives regarding the EM-POC system, it’s usability and the training provided prior to using the EM-POC system.

(1) Human Factors Assessment. A mixed methods study to collect observational and interview data from patient and clinician participants, who will be asked to complete specified tasks through simulated use testing, using: photographs, computer aided design (CAD) models, foam models and functional prototypes of the EM-POC system to identify potential human factors risk, use errors and possible improvements to the design of the system. The system prototypes used in these evaluations will not provide medical therapy. Assessments will be conducted individually with around 23 participants (approximately 20 patients and 3 clinicians) and will be conducted in patient participants’ homes or in the peritoneal dialysis unit. Assessments will be conducted by a human factors expert with over 20 years of experience in medical device product development and will last approximately 90 minutes.

(2) Shadow Study. An open label in-vitro interventional study to test the chemical composition and sterility of PD fluid produced by patient participants using the EM-POC system at home. EM-POC PD fluid will NOT be used for dialysis in any participants. Instead, five patient participants will prepare four bags of PD fluid each day for five days at home using the EM-POC system. The filled PD bags will be collected and sent for testing of chemical composition and sterility. Participants will be trained to use the EM-POC system by a peritoneal dialysis clinical nurse specialist. Adherence will be monitored by daily visits to participants’ homes and collection of filled dialysis bags.

(3) Patient Perspectives. A qualitative research study collecting data through semi-structured interviews from all five participants in the Shadow Study regarding their expectations, experiences and training with the EM-POC system. Daily participant experience will also be collected using a brief questionnaire. All interviews will be conducted via videoconference by an interviewer with extensive experience in qualitative research methods and patient partnership. Interviews will be recorded using videoconference software and transcribed to facilitate data analysis. Interviews will be conducted once with each participant, between one-three weeks following completion of the Shadow Study and take less than 60 minutes.

Timepoint [2] 329977 0
Each bag of PD fluid filled by the participants will be collected the following day for 5 consecutive days and tested for chemical composition.
Primary outcome [3] 329978 0
Sterility of the PD fluid created at the point of care (samples will be tested from each bag of PD fluid for the presence of micro-organisms and endotoxin. If present, identification of micro-organisms will be performed and reported)
Timepoint [3] 329978 0
Each bag of PD fluid filled by the participants will be collected the following day for 5 consecutive days and tested for sterility.
Secondary outcome [1] 404494 0
The volume of delivered PD fluid will be measured by weight for each filled EM-POC PD fluid bag and any difference between the intended and delivered volume will be calculated.
Timepoint [1] 404494 0
Each bag of PD fluid filled by the participants will be collected the following day for 5 consecutive days and tested
Secondary outcome [2] 404495 0
Adverse event and device malfunction reporting, which could include any malfunction of the EM-POC system, PD bag or any reason that a participant is unable to continue using the EM-POC system. Assessment will be conducted using specifically designed questionnaires.
Timepoint [2] 404495 0
Assessment for adverse events and device malfunction will be conducted during the daily nurse visit to the participant's home. These visits will occur on each day of the 5-day study and following study completion.

Statistical methods / analysis
This is an early evaluation study to establish the safety, efficacy and usability of the EM-POC system with Australian dialysis patients.

For the Human Factors Assessments: A sample size of approximately eight participants has been selected for the first formative evaluation. With a sample size of eight participants, a usability problem with a pass rate of 60% or less will be detected with a high probability (at least 69%). The usability testing procedure follows the proposed "optimistic" ANSI/AAMI HE75:2009 approach. The pass rate is assumed to be acceptable unless the testing procedures show overwhelming evidence to the contrary.

For the Shadow Study and Patient Perspectives: A sample size of five participants, producing 100 bags for testing of chemical composition and sterility is felt to be sufficient to provide evidence that the EM-POC system can be used at the point-of-care by patients to produce PD fluid in this early evaluation study. All participants in the Shadow Study will be invited to provide insight into their expectations and experiences through the semi-structured interviews.

Statistical Analysis Plan for the Shadow Study:

Chemical composition: Sodium (mmol/L), chloride (mmol/L), calcium (mmol/L), magnesium (mmol/L), bicarbonate (mmol/L), glucose (mmol/L), pH and osmolality (mOmol/L) concentrations will be measured in the EM-POC PD fluid from each bag. The mean concentrations for each variable +/- standard deviation (SD) will be reported. Frequency distribution graphs for each variable will be plotted.

Sterility: Samples from the EM-POC PD fluid will be tested for the presence of micro-organisms and endotoxin from each filled PD bag. Where micro-organisms are present, identification will be performed and reported. The number and proportion of bags with any detected microbial growth will be reported. Details of bacterial colonization, including identification of bacteria and number of CFUs will be reported. The number and proportion of bags with endotoxin >0.05IU/mL will be reported.
