COVID-19 studies are our top priority. For all other trials, there is a 4-week delay in processing a trial submitted/resubmitted to the ANZCTR and additional delays for updates of registered trials. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Description of intervention(s) / exposure
Participation in this study will involve the completion of seven short questionnaires, relating to participants' current and past experience of pain and breathlessness. These questionnaires will be completed within 24 hours of admission and take place on the ward to which participants are admitted. Completion of the questionnaires will take approximately 30 minutes.

Based on their responses to the questionnaires, participants may then be asked to participate in a face-to-face interview with research staff, which will take between 30-45 minutes and will be conducted at participants' convenience during their admission in a quiet location on the ward to which they are admitted. They will be asked questions about their experience of pain, and they will be asked to reflect on some of the responses provided in the questionnaires. The interview will be audio-recorded and transcribed. From the participants' medical file, information related to their age, smoking history, social history, past medical history, lung condition and current medical and physiotherapy treatment will be collected.

Participants for this project are being recruited over an 18-month period. However, your participation will be limited to completion of the questionnaires in a single session and one interview (where applicable).

Statistical methods / analysis
Based on result of a previous study in which the prevalence of pain was 39.5% (van Dam van Isselt et al., 2019), with a precision of 5%, a 95% confidence level of 95% and a population size of 226 participants admitted with an acute exacerbation of COPD to the Angliss Hospital annually, a total of 141 participants are required.
Point prevalence will be calculated by the number of participant responses of “Yes” to question 1 of the BPI-SF, as a percentage of the total number of participants. Relationships between variables (pain, dyspnoea, pain catastrophizing, breathlessness catastrophizing, HRQoL) will be explored using either Pearson’s correlation coefficient or Spearman’s rank correlation coefficient, depending on the distribution. The significance of these relationships will be interpreted according to Cohen’s effect size for correlation coefficients. Alpha will be set at <0.05.

Brief summary
This project is investigating the presence and experience of pain in people admitted to hospital with an acute exacerbation or flare-up of COPD.

Participants will be asked to complete a series of questionnaires, investigating the presence and experience of pain and breathlessness during an exacerbation of COPD. Based on the results of the questionnaires, participants who report experiencing pain will be invited to participate in an interview to further investigate the experience of pain and how they believe that the symptoms of pain and breathlessness interact during acute exacerbations of COPD.
