Study hypothesis
To investigate the feasibility of improving screening for carriers of the recessively inherited haemoglobin disorders (thalassaemia and sickle cell disorders) in general practice, by using a nurse facilitator to work with primary care teams and the relevant haematology laboratories. To identify problems in communication between all those involved in delivering the service, and to implement solutions.

Condition
Genetic screening for haemoglobin disorders
Intervention
The 13 intervention practices were given: posters, and leaflets to explain to the members of the relevant ethnic groups why carrier testing is advisable and how it can be obtained, an aide-memoire card for GPs¿ consulting rooms listing groups to whom screening should be offered, and a practice reference manual containing background information. Intervention practices were offered three formal practice-based 30-60 minute training sessions from the nurse facilitator during the intervention year. Screening requests from study, control and non-participating practices were recorded using computerised hospital haematology laboratory records.

Primary outcome measures
The main outcome measure was the change in the number of requests for screening tests for haemoglobin disorders made by control and intervention practices in the baseline and intervention years. We also recorded the numbers of requests from the non-participating practices. For the 2 year follow-up trial the main outcome measure was the number of requests for screening tests from each intervention practice in 1997 and 1998.

Eligibility
Participant inclusion criteria
It took place in an area of North London where 29% of residents and 43% of births are in the ethnic groups at risk for haemoglobin disorders (mainly Camden, Islington, Haringey and Enfield). Twenty six of the 93 practices using the services of the Whittington haematology laboratory agreed to take part, and were divided into 13 control and 13 intervention practices.
