Development of an instrument to assess self-management capacity of patients receiving peritoneal dialysis: CAPABLE

Abstract

Background:

Treatment of kidney failure with peritoneal dialysis (PD) at home implies that the patient and/or their caregiver develop a series of skills and basic knowledge about this therapy. There is not a specific inventory of the patient’s abilities to safely perform the PD procedure at home. The objective of this study was to describe the development of an instrument that allows measuring the self-management capacity of patients receiving PD, locating the performance areas that justify the need for intervention by a caregiver.

Methods:

This is a qualitative study developed in three phases: The first phase was the identification of performance areas through bibliographic search and validation of the results with focus groups of experts in PD. The second phase was the design of a system to measure self-management capacities. The third phase was a pilot test of the preliminary version of the instrument applied in 20 incident PD patients.

Results:

Three domains were identified to evaluate the fundamental components of self-management capacity: cognitive and sensory, each one evaluated with four items and motor domain evaluated with eight items. After applying the instrument, we found that 15 patients (75%) did not require support from the caregiver in any of the items. PD patients and nurses found the tool valuable, easy to understand and applicable in the early evaluation of a PD patient.

Conclusions:

We developed an easy-to-administer instrument to measure the self-management capacity of patients receiving PD. This inventory could locate areas that require specific support from a caregiver. Planning an individualised and focused education and training process could result in better health outcomes.
