Remote follow-up using patient-reported outcome measures in patients with chronic kidney disease: the PROKID study – study protocol for a non-inferiority pragmatic randomised controlled trial

Abstract

Background Outpatient care is steadily changing from hospital consultations to other platforms, such as phone consultation and online virtual clinics. It is prudent to maintain quality of care with such initiatives. Currently, patients with chronic kidney disease (CKD) have frequent scheduled visits, but it may be possible to optimise the frequency of hospital consultations using information from patient-reported outcome (PRO) questionnaires filled in at home (PRO-based follow-up). This approach may provide a more individually tailored follow-up based on actual needs for clinical attention. We aimed to evaluate the effectiveness of the quality of care, use of resources and patient outcomes associated with PRO-based follow-up in patients with CKD. Methods This study is a pragmatic, non-inferiority, randomised controlled trial in outpatients with CKD (Grove BE et al., Qual Life Res 27: S143, 2018). Newly referred patients with an estimated glomerular filtration rate (eGFR) of ≤40 ml/min 1.73m 2 will be randomised to either: PRO-based remote follow-up PRO-based telephone consultation Usual outpatient follow-up (control group) In the two intervention groups, a diagnosis-specific PRO questionnaire completed by the patient at home will substitute for usual outpatient follow-up visits. The PRO questionnaire will in part be used as a screening tool to identify patients in need of outpatient contact and to identify focus areas. Responses from the questionnaire will be processed according to a disease-specific algorithm and assigned green, yellow or red status according to patients’ needs. The primary outcome will be loss of renal function evaluated by eGFR. Secondary outcomes are 1. Clinical outcomes, including initiation of acute dialyses, hospitalisation and mortality, 2. Utilisation of healthcare resources and 3. PRO measures, primarily quality of life (Euroqol EQ-5D) and illness perception (Brief Illness Perception Questionnaire (BIPQ). Discussion Benefits and possible drawbacks of the PRO-based follow-up will be evaluated. If PRO-based follow-up proves non-inferior to usual outpatient follow-up, a reorganisation of routine clinical practice in nephrology outpatient clinics may occur. Further, results may impact other patient groups with chronic conditions attending regular follow-up.

Patient-reported outcomes in vaccines research: relevance for decision-making

“… 34 The availability of new technologies has increased the role of virtual clinical trials and the use of mobile clinical trial platforms assessing PROs in conjunction with wearable devices to track participants with no in-person site visits required. 34 Virtual studies have the potential to make clinical studies more inclusive, faster and more cost-effective. 34 This can be achieved using technology, such as smartphones, that study participants may already have available.…”

“… 34 Virtual studies have the potential to make clinical studies more inclusive, faster and more cost-effective. 34 This can be achieved using technology, such as smartphones, that study participants may already have available. Virtual studies bring studies directly to the patients at home, creating a more human approach to clinical research.…”

“…In doing so, studies may be more representative and easier to recruit as well as help retain subjects in an ongoing trial. 34 …”

Enhancing clinical judgement in virtual care for complex chronic disease

“…29 While such an essence may be true for some specialties more than others, each specialty needs to work this out individually based on cost, physical space capacity, need for lengthy history or PE, availability of diagnostic aids, and the role for specialty-specific procedures. Randomized controlled trials by specialty may help assess clinical quality measures, health resource utilization, and patient-reported outcomes, 30 and can also inform statistical reasoning. Telephone consultation vs videoconferencing can be compared.…”
