Using randomised controlled trials (RCTs) to test service interventions: issues of standardisation, selection and...

Area of Science:

• Health Services Research
• Clinical Trials
• Respiratory Medicine

Background:

• Healthcare commissioning relies on evidence of clinical and cost-effectiveness.
• Randomised controlled trials (RCTs) are the benchmark for rigorous evidence.
• Service developments face funding challenges due to limited strong evidence compared to health technologies.

Purpose of the Study:

• To discuss the implications of using experimental methods, specifically RCTs, in service development research.
• To highlight the imbalance in evidence availability between health technologies and service developments.
• To reference an ongoing RCT evaluating components of pulmonary rehabilitation for COPD patients.

Main Methods:

• Discussion of methodological challenges in applying RCTs to service development.
• Reference to an ongoing RCT design for pulmonary rehabilitation.
• Analysis of policy emphasis on patient choice and individualized care within the NHS.

Main Results:

• RCTs are increasingly required for healthcare service commissioning.
• A gap exists in robust evidence for service developments versus health technologies.
• The study uses a pulmonary rehabilitation RCT for COPD as a case example.

Conclusions:

• Experimental methods like RCTs have significant implications for service development research.
• Balancing evidence generation for services and technologies is critical for equitable healthcare funding.
• The findings are relevant to the commissioning and delivery of respiratory care services.
