Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants will be randomised (1:1) to a standard hospital discharge letter or both a standard hospital discharge letter AND a patient directed discharge letter (PADDLE) tailored to their individual situation and explained to them face to face by their physician.
Standard hospital discharge letters are written to the patient's GP. This letter describes the patient's hospital presentation, diagnosis, treatments and recommendations. The letter includes details of investigations and results, and is written using medical terminology for the doctor. All patients receive this standard letter at discharge.
The patient directed discharge letter (PADDLE) is written using lay person's language and focuses on 4 headings: reasons the patient came into hospital, important tests and results, treatment received, and recommendations for when the patient goes home. Information is tailored to each patient's care and includes recommendations for follow up after discharge eg lifestyle changes, further testing, further contact with Health Professionals. Completing this PADDLE letter will take approximately 5 minutes.
The PADDLE letter is written and explained to the patient at the bedside by their treating doctor. This explanation will take approximately 10-15 minutes.

Global knowledge score, calculated as a sum of scores of the 4 domains; 1. reasons for admission and diagnosis, 2. tests performed, 3. treatments received and 4. follow up plan and recommendations. This is a composite outcome.
Timepoint [1] 320538 0
Participant's knowledge of the 4 domains will be will be assessed at week 1 follow up telephone call assessed by a study-specific questionnaire.
Primary outcome [2] 322866 0
Satisfaction:
Satisfaction with hospital care and preparedness for discharge as assessed by study specific questionnaire. This is a composite outcome.
Timepoint [2] 322866 0
Participant's level of satisfaction will be assessed 1 week post-discharge using a study-specific questionnaire.
Primary outcome [3] 322869 0
Adherence to post-discharge recommendations
Timepoint [3] 322869 0
Adherence to post-discharge recommendations will be assessed 1 week post-discharge by study-specific questionnaires. We have 92% power to detect a 30% difference in adherence using a Likert scale (1-5) (average 4.3 versus 3.0 [SD 3.0]) with our proposed sample size (120 PADDLE versus 120 Control subjects).


Secondary outcome [1] 380077 0
Satisfaction:
Satisfaction with hospital care and preparedness for discharge as assessed by study specific questionnaire. This is a composite outcome.
Timepoint [1] 380077 0
Satisfaction with hospital care and preparedness for discharge - at discharge using a study-specific questionnaire.
Participants receiving a PADDLE letter will be assessed at discharge using additional study specific questionnaires to determine satisfaction with the PADDLE letter.
Utilisation of the PADDLE letter will be assessed at 1 week post-discharge.
Secondary outcome [2] 380078 0
Adherence to post-discharge recommendations
Timepoint [2] 380078 0
Adherence will be assessed using study specific questionnaires 1 week post-discharge using participant's self-report. Point score expressed as percentage will be calculated based on participant responses 1 week post-discharge compared with discharge summary.
Secondary outcome [3] 380173 0
Re-hospitalisations
Timepoint [3] 380173 0
Re-hospitalisations will be assessed at 1 week and 6 months post-discharge using study specific questionnaires and confirmed by Medicare data linkage. Medical Benefits Schedule and Pharmaceutical Benefits Scheme claims usage through Medicare Australia will be collected to ascertain use of medical services and prescribed pharmaceuticals.
Note: Re-hospitalisation is listed as a secondary outcome, because the ANZCTR site allows only 3 primary outcomes. We will use re-hospitalisation at 6 months post-discharge as a primary outcome measure. Re-hospitalisation at 1 week and Pharmaceutical Benefits Claim usage will be secondary endpoints.

A secondary knowledge endpoint is the individual score for domain 4: follow-up plan and recommendations . This will be assessed by a study-specific questionnaire..
Timepoint [7] 380299 0
Participant's knowledge of the follow-up plan and recommendations will be assessed 1 week post-discharge by a study-specific questionnaire.

Summary
Brief summary
The overall goal of this study is to see whether we can improve the knowledge patients have about their hospital stay, their satisfaction with their hospitalisation, and their ability to complete the visits and testing that are recommended for when the patient goes home. The reason it is important to conduct our study is that patients may have more complications if they don’t fully understand hospital events and future recommendations at the time of discharge from hospital.
An earlier small study showed that a patient’s understanding and satisfaction of their hospital admission improves when they are provided with a personalised one-page Patient Directed Discharge Letter (abbreviated as PADDLE) discussed with them by the doctor at the bedside.
The purpose of this study is to see whether a newer and more uniform version of the PADDLE letter will be beneficial for patients compared to those who receive the standard hospital discharge letter. The individualised PADDLE will be explained by the treating doctor at the time of hospital discharge and the letter will include the reason for the hospital admission, the tests and treatments received as well as the recommendations for future management.
