Abstract
Purpose: The aim of the systematic review was to explore the role that anxiety plays
in hospital admissions for those with Chronic Obstructive Pulmonary Disease
(COPD). The empirical study aimed to examine whether the frequency of COPD
related admissions is related to psychological factors (anxiety, depression,
catastrophising, and mindfulness), disease severity, perceived disability and
demographic factors. It also sought to examine whether cognitive factors
(mindfulness and catastrophising) may explain unique variance in predicting anxiety
and COPD-related admissions when other relevant factors are controlled for.
Methods: The literature was systematically searched for research related to the
predictive power of anxiety in relation to COPD related hospital admissions. A postal
cross-sectional survey of 54 people with COPD examined the psychological profile
of those who are admitted to hospital for COPD, and if mindfulness and
catastrophising can predict anxiety and COPD hospital admissions. Correlations and
multiple regressions were utilised to explore these hypotheses.
Results: Fourteen studies met inclusion criteria for the systematic review,
demonstrating mixed results regarding whether anxiety plays a role in COPD related
hospital admissions. Findings from the empirical study suggest that a significant
relationship exists between disease severity and number of COPD hospital
admissions and catastrophising and overall mindfulness predicted 16.3% of variance
in COPD hospital admissions (non-significant). Anxiety scores were significantly
correlated with breathlessness, depression, catastrophising and mindfulness with
catastrophising and mindfulness predicting 22.3% of variance in anxiety
(significant).
Conclusions: Further research with robust measures of anxiety and hospital
utilization are needed to aid our understanding of the role of anxiety in COPD related
admissions. Further research is necessary to determine if mindfulness and
catastrophising are useful constructs in predicting anxiety levels and hospital
admissions in those with COPD. This will help to inform future psychological
interventions with this population.
