General information about the trial
|
|||
Main objective of the trial |
To measure feasibility issues including rates of recruitment and loss to follow up, including withdrawal from a randomised trial of a corticosteroid shoulder injection in patients with rotator cuff tendinopathy or adhesive capsulitis.
|
||
Protection of trial subjects |
Risk assessment took place on 22/6/2016 to identify potential risks associated with the trial and IMP. Prior to recruitment of participants, trial GPs underwent study specific training in the assessment of shoulder pain, including the distinction of rotator cuff tendinopathy from adhesive capsulitis and the distinction of these two conditions and other disorders not relevant to this study. They also received training on the injection technique into the subacromial space employed in this trial. Training was led by an academic orthopedic shoulder surgeon from the Nuffield Orthopaedic Centre at Oxford and is based on the British Elbow and Shoulder Society (BESS) Pathway Guideline for Sub-acromial Pain. The trial GPs also received study specific good clinical practice (GCP) training and training in the study procedures (for example, case report form (CRF) completion, safety reporting) from the Primary Care Clinical Trials Unit. The training took less than 1 day to complete.

Frequency threshold for reporting non-serious adverse events: 0% | |||
Notes [1] - There are no non-serious adverse events recorded for these results. It is expected that there will be at least one non-serious adverse event reported. Justification: Both methylprednisolone acetate and lidocaine hydrochloride are commonly used medications in a primary care setting, have well defined safety profiles and are being used for authorised indications. As a result of this no non-serious adverse events will be recorded in this study. |

Substantial protocol amendments (globally) |
|||
Were there any global substantial amendments to the protocol? Yes | |||
Date |
Amendment |
||
13 Nov 2012 |
Substantial amendment with regards to putting up posters in the waiting rooms of the GP surgeries that are participating in the trial. The posters will ask patients if they have shoulder pain and if they match certain requirements of the inclusion criteria. The patients will be asked the speak with the trial GP at the practice for further information.
In addition, to have patient leaflets in the reception areas of the GP surgeries. The leaflets
will detail information about the trial and will ask the patient to contact the trial GP at the practice for
further information. It is anticipated that these documents will help aid the practices in recruiting
participants. |

Interruptions (globally) |

Were there any global interruptions to the trial? No | |||
