The investigators have developed a way of improving primary health care for people who have CRD, who often also have other long term health conditions. It is a patient management tool (PMT), that is, a printed manual of flowcharts taking doctors and nurses from symptoms to diagnoses to treatments, tests or referrals, with advice on how to make decisions along the way about diagnoses, tests, treatments and referrals. They are prompted to think of other diseases and health problems that might be undetected or neglected. The package also includes a method of training known as outreach education. First trainers are trained, then trainers train groups of doctors and nurses at their workplaces, showing them how to use the guidelines, and using their own patients and clinical problems as examples. This outreach training is repeated several times in short sessions. The investigators' research in Africa has shown that this approach can be effective, cost effective, feasible and sustainable. It has been rolled out throughout South Africa and other African countries. But it has have not yet been shown to be effective for this combination of diseases (CRDs together with cardiovascular disease, diabetes, tuberculosis and back pain). The investigators have also not tried or evaluate it in Latin American countries, which have different health systems, and have many more doctors providing primary health care. Now co-investigators in the Brazilian city of Florianopolis have decided to put this educational package in place throughout the city, and have agreed to do so as a randomised controlled trial. This will clearly show whether PACK Brazil is effective, cost effective and feasible under Brazilian conditions.
