Plain English Summary
Background and study aims
Avoiding unnecessary use of hospital services is one of the biggest challenges currently facing the NHS. Chronic obstructive pulmonary disease (COPD) is one of the most common lung diseases in the United Kingdom and accounts for 10% of hospital admissions each year. Nearly a third of these patients are readmitted to hospital within 28 days of discharge. COPD care bundles could play a key role in resolving the issue of unplanned admissions. Care bundles are a way of ensuring that staff provide a coordinated package of care to patients with COPD when they arrive at and are sent home from hospital. This study aims to evaluate the effectiveness of care bundles as a means of improving hospital care and reducing re-admissions for patients with COPD.
Who can participate?
This study will include a group of up to 20 hospitals in England and Wales who have already agreed to implement the COPD care bundles, and up to 20 ‘comparator’ hospitals who will not be delivering them.
What does the study involve?
By comparing how many patients are readmitted to each type of hospital over a two-year period, and what happens to patients during their stay, we will be able to assess how successful COPD care bundles are. More specifically, we will look at the number of patients admitted with COPD, the number of deaths of COPD patients while in hospital, the number of days spent in hospital by patients with COPD, the proportion of patients with COPD who are readmitted, the number of COPD patients seen and discharged from A&E, levels of satisfaction in patients with COPD, how patients with COPD are managed in hospital, and how much it costs to care for a patient with COPD in hospital and after discharge. Most of the information needed for this study is routinely collected by hospitals in the course of their own management activity.
What are the possible benefits and risks of participating?
The benefit of taking part in the study for either NHS Trusts or individual patients is the opportunity to participate in a national high-quality evaluation of service delivery which will provide new evidence on the effectiveness of an aspect of NHS care provision. The risks of participation are minimal.

An evaluation of the effectiveness of ‘care bundles’ as a means of improving hospital care and reducing hospital readmission for patients with chronic obstructive pulmonary disease (COPD)
This research seeks to evaluate the effectiveness of care bundles (i.e., a co-ordinated package of care) as a means of improving hospital care and reducing re-admissions for patients with chronic obstructive pulmonary disease (COPD).

Topic: Respiratory disorders; Subtopic: Respiratory (all Subtopics); Disease: Respiratory
The intervention is the delivery of a COPD care bundle at either the point of admission to or discharge from hospital.
Primary outcome measure
COPD re-admission rates; Timepoint(s): 28 days post-discharge
Secondary outcome measures
1. Compliance with delivery of COPD care bundles; Timepoint(s): 12 months pre- and post-
2. COPD re-admission rates; Timepoint(s): 90-days post-hospital discharge
3. Costs of in-patient medications and procedures; Timepoint(s): 12 months pre-and post-
4. In-hospital mortality; Timepoint(s): 12-months pre- and post-
5. Length of stay for patients with COPD; Timepoint(s): at end of 12-month data collection
6. Mortality; Timepoint(s): 90-day post-hospital discharge
7. Overall re-admission rates; Timepoint(s): 28-days post-hospital discharge
8. Time taken to deliver COPD care bundles; Timepoint(s): post-admission or pre-discharge
9. Total number of COPD admissions; Timepoint(s): monthly
10. Total number of patients for whom COPD care bundle used; Timepoint(s): 12-months post-hospital data collection
As with the primary outcome, the secondary outcomes of the study will be measured for a 12-month period pre-and post- a particular index date. This index date is the date upon which an individual implementation site i.e. NHS Trust began to deliver its COPD care bundle or, in the case of comparator sites, the date upon which an individual site's matched implementation site began to deliver its COPD care bundle. This approach will ensure that data are collected during the same ‘before’ and ‘after’ period for matched implementation and comparator sites.

Participant inclusion criteria
1. People over 18 years of age admitted to an acute hospital with COPD
2. Primary cause of admission is COPD (ICD10 diagnostic codes J41-44)
Target Gender: Male & Female ; Lower Age Limit 18 years
Target number of participants
Planned Sample Size: 76; UK Sample Size: 76; Description: 60 patients + 16 trusts. Study comprised of 3 levels of research. Level 1 is not consenting and uses publicly available data. Level 2 is 'consents' at a trust level and will recruit 'up to 16' trusts and level 3 is patient-consented case studies and aims to recruit 10 patients per site from 'up to 6 sites'. May also include some patient carers and healthcare professionals where available. Mixed method study combining both quantitative and qualitative approaches - no formal sample size calculation. Total final enrolment was 14 trusts and 55 participants for the qualitative study.
