Factors influencing renal replacement therapy modality choice from the nephrologist's perspective

BackgroundPeritoneal dialysis (PD) offers quality of life and empowerment for persons with end-stage kidney disease (ESKD). Nevertheless, the prevalence of PD is low in Belgium and Europe in general. Reimbursement, patient mix and late referral have been quoted as underlying reasons. However, to date no one-size-fits-all solution increasing uptake of PD has been successfully implemented.We aimed to understand the nephrologist's perspective, beliefs, and experiences on dialysis modality selection and to clarify underlying process-level and intrinsic motivations steering final decisions.BackgroundPeritoneal dialysis (PD) offers quality of life and empowerment for persons with end-stage kidney disease (ESKD).

However, to date no one-size-fits-all solution increasing uptake of PD has been successfully implemented.We aimed to understand the nephrologist's perspective, beliefs, and experiences on dialysis modality selection and to clarify underlying process-level and intrinsic motivations steering final decisions.MethodsUsing purposeful sampling, Belgian nephrologists (non-/academic, geographical spread, age, gender) were selected. We conducted semi-structured interviews, and audiotapes were transcribed verbatim. Meaningful units were grouped into (sub-)themes, and a conceptual framework was developed using grounded theory according to Charmaz as guidance.ResultsTwenty-nine nephrologists were interviewed. We identified four themes: Trust and belief (in PD as a technique; own expertise, knowledge and team; in behavior of patient, family practitioner), feeling of control (paternalism; insecurity; prejudice), vision of care and approach (shared decision making; troubleshooting attitude; flexibility and creativity; complacency), and organizational issues (predialysis; access; financial; and assisted PD).ConclusionsBased on these interviews, it is apparent that next to already identified singular issues such as late referral, predialysis education, patient mix and financial incentives, more intrinsic factors also impact uptake of home-based therapies. These factors intertwine and relate both to process-level topics and to attitudes and culture of the nephrologists within the team.
