[Paramedical staff knowledge and practice related to the blood transfusion safety].

Blood transfusion is a complex activity, involving many actors. It is a high risk activity which couldn't be controlled without the use of specific methods. Health care workers beliefs and organisational factors are two major issues for the blood transfusion safety. Our study objectives were to describe the paramedical staff's knowledge and practice regarding blood transfusion safety and to identify factors that are related to them. We carried out a cross sectional study. The information was gathered by using a questionnaire. The latter was developed by foreign teams and adapted to the local context. Two outcome measures were used: the knowledge and practice score and the proportion of true answers. The study showed that only 15% of the interviewed persons have had a score less than 30 (scale range from 0 to 100), i.e. only 15% have had appropriate knowledge and practice with no negative consequences for the patient safety. 13.8% of the study population provided right answers related to the biologic exams required before red cells transfusion and 34% for the abnormal reaction circumstances. These results underscores the importance of strategies improving the quality and the safety of blood transfusion, i.e. the continuous medical education, implementing a blood transfusion information system and the use of transfusion practice guidelines.

[Analysis of the appropriateness of hospitalizations in Monastir, Tunisia].

We aimed to measure the extent of inappropriate hospital admissions and to identify factors associated with inappropriate hospital use. A descriptive study was carried out on a randomized sample of 411 hospitalizations in 3 regional hospitals. The appropriateness of admissions was assessed using the Appropriateness Evaluation Protocol (AEP). We found 21% (95% CI: 17%-25%) of the admissions were avoidable according to the AEP. Inappropriate admissions were associated with the hospital (P = 0.005), patient age (P = 0.003), length of stay and diagnosis (P < 0.001). The most frequent reasons for appropriate admissions were parenteral therapy, an acute or progressive sensory motor circulatory or respiratory condition sufficient to incapacitate the patient and severe electrolyte or blood gas abnormality. Our study highlights the need to improve hospital management and to develop alternatives to hospitalization.

[Risk factors for eclampsia: a case-control study].

OBJECTIVE: Our purpose was to characterize the risk factors of eclampsia in women with preeclampsia. PATIENTS AND METHODS: A case-control study was conducted at Monastir hospital to investigate risk factors for eclampsia between 1st January 1995 and 30th June 2000. Cases were matched to preeclamptic controls on a 2:1 ratio. Univariate analysis was used to determine which of the independent variables were significantly different between the groups. Those with significant differences were then entered into multiple logistic regression analysis to determine the characteristics that were independently related to eclampsia. RESULT: A total of 41 cases of eclampsia were ascertained from deliveries. The ratio of eclampsia cases to number of deliveries over the study period was 1.87 per 1000. The first seizures occurred at home in 59% of the cases. Univariate analysis revealed statistical significance for the following variables associated with eclampsia: systolic hypertension > or =160 mmHg and diastolic > or =110 mmHg, headache, visual symptoms, vivid deep tendon reflexes, proteinuria >3+ or >3 g d(-1), uric acid concentration > or =350 micromol l(-1), serum creatinine concentration >100 micromol l(-1) and aminotransferase aspartate >30 IU l(-1). A history of abortion appears to be the protective factor against eclampsia. However, with subsequent multivariate analysis, only vivid deep tendon reflexes and elevated uric acid concentration remained significant. CONCLUSION: These data indicate a need for improved prenatal care and medical attention focused on prodroms of eclampsia as well as the detection of preeclampsia to reduce the incidence of eclampsia.

[Epidemiology of cholelithiasis in central Tunisia. Prevalence and associated factors in a nonselected population].

OBJECTIVES: The prevalence of cholelithiasis is still unknown in Tunisia. The aim of this study was to assess the prevalence and selected risk factors of cholelithiasis METHODS: Two thousand citizens over the age of 19 in a small town in the center of Tunisia were evaluated. Following a structured interview of each subject, an ultrasound examination was performed. Height, weight and blood levels of glucose and cholesterol were determined by standard methods. RESULTS: The response rate was 56% (746 women and 377 men). Of the 1123 persons evaluated, 19 had undergone previous cholecystectomy. Crude prevalence of cholelithiasis was 4% (5.4% in women and 1% in men). Typical biliary colic was the only symptom significantly associated with cholelithiasis (specificity: 97.6%). Presence of gallstones was associated with age (P=0.02), sex (P=0. 00045) and multiparity (P<0.0002). Neither body mass index, diabetes mellitus or hypercholesterolemia were risk factors. CONCLUSION: The prevalence of cholelithiasis in central Tunisia is low. The risk factors are similar to those in occidental surveys.

[Evaluation of mothers' knowledge in pre- and postnatal preventive care in the Tunisian Sahel].

Maternal and child health is one of the major concerns of public health throughout the world. Health education and increased knowledge of mothers in relation to their health is a strategy of choice adopted in many countries for improving maternal and child health. It is within this framework that this action is being carried out, which aims to evaluate the knowledge of mothers in the area of preventive care for women. A cross-sectional survey was carried out among 915 parturient women from the Monastir region (coastal region of Tunisia) at the time of delivery, between May 1 and July 26, 1996. The survey was based on a questionnaire that explores, in addition to the socio-demographic characteristics of parents, the level of surveillance during pregnancy and mothers' knowledge in relation to preventive care of women. The majority of women (95%) are aware of the importance of prenatal surveillance, yet 12% don't have any knowledge of the recommended number of prenatal visits. Concerning contraception, the tetanus vaccination and the post-natal consultation, knowledge concerning their importance is high, but practice in these areas is not. Roughly only 1/3 of mothers used contraception before their current pregnancies, and only 70% had both doses of the tetanus vaccination. Health education on preventive care received by the mothers helps increase knowledge and probably practices as well. The increase in mothers' knowledge happens with appropriate initial and continued training in health education, provided by health professionals and with the reinforcement of educational activities during each contact with the mother both during her pregnancy and in periods where she isn't pregnant.

Diabetes and hospital morbidity in the Monastir governorship (Tunisia).

Diabetes is a public health problem worldwide. In Tunisia, the rate of prevalence is 3.8% in urban areas and 1.3% in rural areas, whereas the socioeconomic impact of the disease has rarely been investigated. This study conducted in the Monastir health district evaluated the burden of hospital care for diabetes. All admissions for diabetes (973) recorded in the regional morbidity register during 1993 for all public hospitals in the region were taken into consideration. Admission for diabetes represented 5.9% of total admissions and was the first cause of hospitalisation. The university hospital centre received 40% of these patients. The annual hospital rate of diabetes is estimated to be 2.7%, but varies according to the district considered and the age of patients (1.1% for those under 50 years of age and 12.8% for those over 65). The number of days of hospitalization related to diabetes was 10,069, i.e. 7.6% of the total for the district. The mean cost of a single hospitalization is about 251 Tunisian dinars (US$251). Diabetes treatment could be improved and the cost lowered by providing appropriate ambulatory care and health education to reduce hospital admissions.

[Antibiotic therapy in general medicine in Monastir, Tunisia].

In order to determine the cost and frequency of antibiotic prescription by general practitioners, we studied 563 outpatients from health centres in Monastir (Tunisia). All patients had acute diseases. Antibiotics were prescribed to 50.4%. Single antibiotics were generally prescribed, but 52.8% of these patients did not have any laboratory tests. The more frequently used antibiotics were penicillin G and A. Antibiotics cost represented 34.7% of medicinal cost borne by patients and 49.7% of the cost borne by the public sector. Rationalization of medicinal prescription would have a positive impact on household and state budgets.

[Essential drugs: availability and prescription in Monastir (Tunisia) health district].

Shortages in the availability of some drugs are sometimes noted in primary health care (PHC) centres in spite of the steady increase in the drug budgets in Tunisia. We conducted a survey therefore in 1998 in the health district of Monastir to study the availability of certain essential drugs (n = 15) in PHC centres and the main features of the drug prescription. We found that the drugs lacking were generally those prescribed for chronic diseases and as well as oral antibiotics. Antibiotic treatment constituted 71.8% of public prescriptions and 32.3% of these prescriptions were for an injectable treatment.

Atraumatic restorative treatment and glass ionomer sealants in Tunisian children: survival after 3 years.

We evaluated the survival rates of atraumatic restorative treatment restorations and of glass ionomer sealants after 3 years of usage in primary and permanent teeth in Tunisian children aged 3-15 years attending rural schools, and assessed the presence or absence of dental caries in the restored teeth. After an initial survey of 1949 children, 242 were selected and agreed to undergo treatment. The loss to follow-up after 3 years was about 40%. Of those evaluated, 45.73% of one-surface ART restorations in permanent teeth had survived, 54.96% of one-surface sealants in permanent teeth had survived and 27.85% of one-surface ART restorations in primary teeth had survived. Caries was found in only 19 teeth after 3 years.
