AIM. A screening clinic for Bangladeshi families was established in order to improve the health care provided by one general practice to its Bangladeshi patients. METHOD. The clinic was run by a general practitioner, a health visitor and a Bangladeshi health worker. Patients were invited to attend household by household. The composition of each household was recorded using a genogram. Details of family illness, housing and employment were noted. A medical history was taken from each individual. Every adult was screened for diabetes and risk factors for coronary heart disease; cervical cytology was offered to women. The immunization status of all patients was recorded and adults were immunized. Children were referred to the child health clinic for immunizations. The clinic concluded with a health education session focusing on smoking, exercise and diet. RESULTS. Over a two year period, 58% of the Bangladeshi families registered with the practice attended the clinic, a total of 207 people. Meeting Bangladeshi patients household by household was an effective and apparently efficient way of providing basic screening and health education. It allowed the practice to learn about the structure of its Bangladeshi families, the social problems faced by their community, and the areas in which their health care could be improved. CONCLUSION. This clinic provides a model which could be adapted for use with other ethnic or 'hard-to-reach' groups. It may also prove an effective way of screening all families in general practice.
