Adherence to management guidelines in acute respiratory infections and diarrhoea in children under 5 years old in primary health care in Botswana.

OBJECTIVE: To evaluate health care providers' adherence to management guidelines for acute respiratory infection and diarrhoea in children under 5 years old in Botswana primary health care. DESIGN: Cross-sectional prospective field survey. Data collection was carried out through observation of consecutive consultations at 30 randomly assigned clinics and health posts in three purposely chosen districts. STUDY PARTICIPANTS: This study comprises 185 cases of acute respiratory infection and 85 cases of diarrhoea. MAIN MEASURE: Criteria for acceptable standards of history taking and physical examination for acute respiratory infection and diarrhoea were defined as well as criteria for categorizing the appropriateness of antibiotic prescription. The percentage of oral dehydration salts provided in cases of diarrhoea was calculated. RESULTS: Acute respiratory infection and diarrhoea accounted for 270 (including 15 missing cases) of all main diagnoses (n = 539). In 262 cases (97%) health care providers were nurses or enrolled nurses; in 3% family welfare educators. Acceptable history taking, physical examination, and both combined in acute respiratory infection was found in 113 (63%), 32 (18%), and 28 (16%), and in diarrhoea in 45 (58%), 26 (34%) and 20 (26%) cases, respectively. Antibiotics were prescribed in 76 of 255 (30%) cases. Prescription was assessed as inappropriate in 56 of 76 (74%) of all cases; in 41 of 52 (79%) cases with acute respiratory infection, in none of the pneumonia cases, and in all 15 cases of diarrhoea. Oral rehydration salts were prescribed in 74 (87%) of the diarrhoea cases. CONCLUSIONS: Health care providers' adherence to guidelines on history taking was suboptimal in acute respiratory infection and diarrhoea but poor on examination in both conditions. A high level of inappropriate antibiotic prescription was found in acute respiratory infection and diarrhoea. Overall, there is considerable scope for improving diagnostic and therapeutic management of these major childhood diseases in Botswana primary health care.

African sleeping sickness is no longer a rare disease among tourists visiting national parks in Tanzania. The disease is caused by a parasite, Trypanosoma brucei, which is transmitted by the tsetse fly. Two species infect humans: Trypanosoma brucci gambiense and Trypanosoma brucei rhodesiense; the last form is re-emerging in parts of Africa. Untreated this disease carries a mortality of nearly 100%. This article describes a case of African sleeping sickness in a tourist visiting Tanzania, which was diagnosed at the Nordic Clinic, Dar es Salaam. The most important symptoms, diagnostic investigations as well as the main principles of treatment are described. Patients with this condition need to be admitted and treated at centres with competence in tropical diseases. African sleeping sickness should be kept in mind in tourists returning to their home country with fever after visits to national parks in Eastern Africa. With early treatment, cure is almost certain. The only way to prevent this condition is through protection against bites of the tsetse fly.
