Brief Summary

Developmental dysplasia of the hip (DDH) is one of the most common inborn diseases. Early diagnosis of this condition is very important and it can be harmful both to miss DDH and label normal infants as having DDH. Why DDH can be missed or labelled to normal children is not well understood but can be related to the doctor's knowledge, skill and the way the hip consultation is conducted. This research aims to help overcome these issues and proposes the use of a diagnostic aid (checklist) for DDH in general practices (GP). The Investigator will divide general practices (GP) in England into two groups. One group will use our checklist for all hip checks they carry out. The other group will work as they usually do, without the aid. The study wishes to compare if GPs who use the checklist will do better in identifying babies with DDH than those who do not use our checklist. The Investigator will also evaluate whether using the checklist reduces costs for families around trips to doctors or hospitals, and costs to the NHS (National Health Service). In addition The Investigators will interview general practitioners, health visitors and carers of infants to elicit their perceptions about the intervention. The study will include GPs registered in England who carry out the 6-week hip check and agree to being randomised and to hospitals releasing data on infants they had examined during the study period. Practices planning to close within 12 months of the start of the study are not eligible. Eligible infants will be identified by general practice patient registers and infants will be invited to attend a 6-week check at their local practices, the research sites. The study plans to include a total of 152 practices in this study and will collaborate with 15 NIHR (National Institute of Health Research) CRNs (Clinical Research Network) to recruit GP practices with efficient and existing infrastructure.

Outcome Measures

Primary Outcomes (1)

  • Clinical Importance of referrals

    Number of referred hips that are considered clinically insignificant (referrals resulting in reassurance and discharge from secondary care).

    2 weeks following hip check

Secondary Outcomes (12)

  • Number of appropriate referrals per GP practice

    Within 2 years of hip check

  • Number of Late diagnoses

    Within 2 years of hip check

  • Consequences of Late diagnoses

    Within 2 years of hip check

  • Volume of referrals

    Within 2 years of hip check

  • Timeliness of referrals

    Within 2 years of hip check

  • +7 more secondary outcomes

Diagnostic Test: The 6-week Hip Checklist

Standard of Care

NO INTERVENTION

The control group will assess infants according to standard practice, during the 6-week hip check.

Interventions

Eligibility Criteria

Age6 Weeks - 11 Weeks
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • General practices (GP) registered in England and who carry out the 6-week infant hip check as part of their routine work.
  • Practice using either EMIS or SystemOne clinical computer systems
  • General practitioners recording all 6 week baby hip examination on their computer template
  • GPs willing to give informed consent to (a) being randomized, (b) willing to undergo observations, interviews and questionnaires and (c)collaborating secondary care facilities releasing data about all infants undergoing the 6-week hip check GP practices during the duration of the randomised controlled trial.
  • GPs conducting the 6 week check must agree to view the training video on the examination of babies' hips at 6 weeks at baseline
  • In the study practice, infants who are eligible for this study will be those presenting to any of the practices if aged \<11 weeks when the 6-week check is done in the GP practice.

You may not qualify if:

  • Any GP practice that is to close down within 12 months of when the first patient would be recruited in this practice.
  • Parents/carers aged under 18
