Study limitations
1 This study was designed only to explore the impact of
interactive education multimedia DVDs on ESRD patient
dialysis knowledge, uncertainty and decision-making. With
patient autonomy increasingly emphasised in health care,
the authors suggest that future relevant researches should
integrate concepts such as patient autonomy, self-efficiency
and health belief models to explore the impact and application
of such DVD interventions on medical autonomy in
patients with ESRD.
2 Because of limited time, manpower and budget, this study
only traced research results for a four-month post-test
period. As patients with ESRD accepting dialysis may yield
different health problem levels, the authors suggest that
future research further extend the post-test observation
period to understand time effects and evaluate patient
decision-making satisfaction over the long term.
3 In the light of the limited follow-up period (four months) and
the limitation of the sample to outpatients and inpatients at
certain medical centre in southern Taiwan, the authors
suggest future researchers expanding the research in terms of
both time and space to enhance result rigour.
