Inter-observer variation in paediatric clinical signs between different grades of staff examining children admitted to hospital in Tanzania.

BACKGROUND AND OBJECTIVE: Children are often admitted to district hospitals in Africa without an adequate record of clinical examination, a problem that could be reduced by greater involvement of nurses in their assessment. We aimed to ascertain whether hospital nurses in a district hospital could conduct paediatric examinations as reliably as clinical staff, when provided with a short structured training session. METHODS: Hospital nurses (HN), hospital clinical officers (HCO) and research clinical officers (RCO) repeated examinations on children admitted to the paediatric ward shortly after the first examination by an RCO. Kappa scores were used to compare the agreement on the presence or absence of basic clinical signs by different categories of staff. RESULTS: Among 439 paired examinations the agreement between RCOs on clinical signs was slightly higher than for HCOs or HNs; the mean (median) Kappa scores for all signs examined were 0.54 (0.57) for RCO-RCO, 0.49 (0.49) for RCO-HCO and 0.50 (0.49) for RCO-HN. Levels of agreement were lower if children were under the age of 18 months or if they cried during the examination. CONCLUSIONS: Nurses with basic training appear to perform as well as clinically trained staff in eliciting essential signs in acutely ill children. Their role in the initial and ongoing assessment of these children should be reviewed in light of the critical shortages in clinically trained staff in African hospitals.

STD rapid assessment in Rwandan refugee camps in Tanzania.

OBJECTIVE: To obtain baseline information on sexually transmitted diseases (STDs) in the Rwandan refugees camps in Tanzania, prior to establishment of STD services. SETTING: The largest camps of Rwandan refugees in the Ngara District of Tanzania (estimated population 300,000). The study was carried out in 8 days in August 1994. SUBJECTS AND METHODS: A rapid assessment technique was used to measure STD prevalences among: (i) 100 antenatal clinic attenders (ANC); (ii) 239 men from outpatient clinics (OPD); and (iii) 289 men from the community. Interviews (by questionnaire) and genital examination were performed for all participants; sampling for females included genital swabs for the the diagnosis of Neisseria gonorrhoeae (NG), Candida albicans (CA), Trichomonas vaginalis (TV), bacterial vaginosis (BV) and a blood sample for syphilis serology. Men provided urine samples which were screened for leucocytes using the leucocyte esterase (LE) dipstick; urethral swabs for Gram stain were taken from men with a reactive LE test and from those with symptoms or signs of urethritis. OPD males provided a blood sample for syphilis serology. RESULTS: All groups reported frequent experience with STDs and engaging in risky sexual behaviour prior to the survey. During the establishment of the camps, sexual activity was reportedly low. Over 50% of ANC attenders were infected with agents causing vaginitis (TV/BV/CA) and 3% were infected with NG. The prevalence of active syphilis was 4%. In the male outpatients, the prevalence of urethritis was 2.6% and of serological syphilis was 6.1%. Among males in the community, the prevalence of urethritis was 2.9% (the majority being asymptomatic infections). We noted frequent over-reporting of STD symptoms, unconfirmed clinically or biologically. CONCLUSIONS: STD case detection and management should be improved by training health workers in using the WHO syndromic approach, and through IEC campaigns encouraging attendance at clinics. Rapid epidemiological methods provide quick and useful information at low cost in refugee camps.

Taking early action in emergencies to reduce the spread of STDs and HIV.

PIP: The disintegration of family life, disruption of social norms, poverty, and commercial sexual activity associated with the lives of Rwandan refugees in camps in northwest Tanzania increase their susceptibility to sexually transmitted diseases (STDs), including human immunodeficiency virus (HIV). To prevent such an outcome, the African Medical and Research Foundation proposed that STD/HIV interventions be launched under the auspices of the governing body in the refugee camps. A rapid assessment methodology survey was conducted to acquire baseline data for resource allocation (drugs and personnel), case finding strategies, and staff training. Each refugee community was visited by a team of specially trained health behavior promoters who presented a four-part IEC package: sensitization of camp leaders, general STD/HIV awareness, STD treatment-seeking behaviors, and sexual behavior modification through peer education. Condoms and health education materials were distributed by peer educators. STD services have been introduced to outpatient, family planning, and prenatal clinics in the camps. Although HIV testing was not undertaken for political reasons, pregnant women at three camps received screening for syphilis. Such STD control interventions should become a standard component of refugee assistance.^ieng
