[Hysterectomy for benign lesions in Brittany: analysis of medical practices]. / Hystérectomies pour pathologie bénigne en région Bretagne: analyse des pratiques.

OBJECTIVES: By who, why and how are done hysterectomies for benign lesions. MATERIAL: and methods. The 413 medical files of all the patients who underwent an hysterectomy for benign lesion during the last trimester of 1997 were recorded by the Medical Information Departments of the 53 health establishments of the Brittany Region. Surgical procedures, medical indications, pathological findings were analyzed according to the guidelines encountered in the medical literature. RESULTS: Hysterectomies were done by many surgeons (112). Inaugural signs noted in the medical files were classical, but various and often associated without a main indication of hysterectomy. Histological diagnose were identical with those found usually in the literature. The abdominal route was mainly used, particularly when the operation was done by a generalist surgeon and in case of uterus weight superior to 250 g. The post operative outcome has revealed the same nature and frequency of complications as usually described. CONCLUSION: In this study, it appears that efforts remain necessary to clarify the indications for hysterectomy in the medical files (in order to promote the alternative procedures to the hysterectomy), and that the proportion of hysterectomies performed by the abdominal route should be reduced in aid of the others surgical routes.

-Anesthesia and analgesia practice patterns in French obstetrical patients-. / Anesthésies et analgésies pratiquées dans les maternités françaises.

OBJECTIVE: To assess the rate of epidural analgesia (EA) for parturition and the techniques of anaesthesia for Caesarean section (CS). STUDY DESIGN: Retrospective study. PATIENTS: A series of 84,235 deliveries. METHODS: The series was extracted from a total of 770,054 deliveries carried out in 1991, according to the number of births in each hospital (1/1 if the births were < or = 100 per year, up to 1/25 if they were > or = 2,000 per year). The data analyzed included: anaesthesia technique, whether or not there was an anaesthetist on night duty at the hospital, birth rate in the hospital, type of hospital: university (UH), general (GH) or private (PH). For vaginal deliveries, the mode of labour commencement (spontaneous or induced), the multiplicity of pregnancies and a history of past CS were also noted. RESULTS: Vaginal deliveries: the overall rate of EA was 37.2%. EA were not carried out in 5% of maternity hospitals. In cases of spontaneous labour, the average rate was 32.1%, significantly less than for induced labour (59.6%, P < 0.0001) and in cases of previous CS (39%, P < 0.05). There was no statistical difference in cases of multiple pregnancies (35.7%). The average rate of EA was correlated to the number of annual births (P < 0.001) and was increased when the anaesthetist was present in hospital at night (P < 0.001). It was also significantly lower in GH (P < 0.001) than in UH or PH, which were equivalent. Scheduled CS: general anaesthesia (GA) was carried out at a significantly higher rate than regional anaesthesia (RA) (49.7% vs 48.4%, P < 0.05). In 15.1% of hospitals, RA was not available. The incidence of RA was influenced neither by the rate of annual births nor by the presence of the anaesthetist in the hospital during night. However, RA was significantly less frequent in GH (46.3%, P < 0.001) than in UH (48.6%) and in PH (53.6%) which were equivalent. CS during labour: the incidence of RA was significantly higher than GA (53.2% vs 44.1%, P < 0.001). In 17.1% of hospitals, RA was never carried out. The rate of RA was correlated to the size of the maternity hospital, and significantly higher (P < 0.001) when the anaesthetist was present in hospital during night. The differences between UH, GH and EP were the same than for scheduled CS. CONCLUSION: In France in 1991, the average rate of 37.2% for EA for obstetrics was high when compared to the rate in United Kingdom. It was equivalent to those in United States and Ontario, Canada. The discrepancies between hospitals were mainly related to structural and organizational factors. The influence of the size of the maternity hospital, the 24-hour service of EA was also shown in other studies. However, the difference between GA and UH and PH is a French particularity. The high rate of GA for CS differs largely with those in the UK or the USA. The time saving aspect of GA was probably an important factor for the choice of this technique. This study must be reactualized and enlarged to determine the demand of EA for labour by parturients and obstetricians.

[Type of birth center and conditions of transfer of neonates under 1500 g or gestational age under 33 weeks]. / Lieux de naissance et conditions de transferts des enfants de moins de 1500 g ou d'âge gestationnel strictement inférieur à 33 semaines.

BACKGROUND: Perinatal care's organization has been widely discussed in France during this last decade. Until now, transfer of high-risk neonates from their birth maternity to a pediatric unit using mobile vehicles led by specialized teams is encouraged in this country. POPULATION AND METHODS: Retrospective analysis of the type of maternities of birth for a population of 717 newborns, weighing less than 1,500 g and/or of gestational age under 33 weeks, extracted from a sample of 84,279 births in 1991. RESULTS: Only 15.6% of studied births took place in a maternity including a special intensive care pediatric unit (international level 3); 58.7% of those newborns where transferred outborn. There was a significant difference between the immediate access of newborns to a level 3 pediatric unit according to the location-of birth: significantly fewer newborns were directly transferred to a level 3 unit when born in a facility that included a level 2 pediatric unit, compared with those born in facilities that included a level 1 or 3 pediatric unit. CONCLUSION: Strong efforts should be made to identify mothers at high risk of giving birth to extremely prematured babies or babies with a very low birthweight so that births could take place in maternities properly equipped for their care. Perinatal care's organization should be built on a hierarchical network of maternities and pediatric services related to the risk of the population. Accreditation of maternities and pediatric services could help moving towards this kind of organization.

[Analysis of delivery facilities and conditions in 1991 in mothers of infants with birth weights below 1500 grams and/or gestational age under 33 weeks]. / Analyse des lieux et des conditions d'accouchement en 1991 des mères d'enfants dont le poids de naissance était inférieur à 1500 g et/ou l'âge gestationnel inférieur strictement à 33 sem.

AIMS: To identify maternities (in terms of level of activity and linkage with pediatric services) where, in 1991, mothers gave birth to infants of gestational age less than 33 weeks and/or with birth weight under 1500 g. To analyse factors linked to the probability of choosing a particular maternity as place of delivery for this population and measure the impact of maternal transferts on the rates of deliveries. To estimate the number of neonate transferts which could be avoided with simple recommendations. To propose policies that would allow France to come closer to the results of other reference countries in term of management of obstetrical and neonate care. MATERIAL AND METHOD: We extracted from a retrospective sample of 84,279 births (out of a total of 770,148), 717 infants meeting previously defined criteria and related to the population described above, using univariate and multivariate analysis and logistic regression. RESULTS: The Odds-ratio for a delivery to take place in a maternity with a volume of more than 2000 deliveries a year, compared with those doing less than 300 deliveries, is 4, 12. Only 15.8% of those deliveries took place in maternities linked to a level 3 pediatric unit (i.e where an intensive care neonates unit was located in the same building). 39.5% of births took place in level 1 maternities where no required pediatric service existed. Logistic regression techniques showed that the choice of a maternity for mother referral was more linked to the number of deliveries than to its level of pediatric services. In the studied population, 46% of the difference between the observed number of births in high volume maternities (compared to the expected number) could be explained by a maternal referral. The analysis of deliveries showed that for 34% of mothers who gave birth to a baby in a level 1 or 2 maternity, there was a possibility of being referred easily in a level 3 maternity. CONCLUSION: This study shows that the level of care of mothers at high risk of delivering a very premature and/or hypotrophic infant is far from international standards. Simple actions could double the number of births taking place in adapted maternities. We propose to both obstetricians and pediatrists, a common program to enhance the level of care.

[Cesarean sections in France: impact of organizational factors on different utilization rates]. / Césariennes en France: impact des facteurs organisationnels dans les variations de pratique.

In this study, we analysed the potential impact of organizational factors to explain the variation of cesarean sections' rates. We used a retrospective sample of 84,372 deliveries and two subsamples of low risk deliveries for cesarean sections. We determined different organisational factors that included: juridical and financial status of maternities, their architecture, the type of on-call for obstetricians, pediatrists and anesthetists, the annual number of deliveries and the level of pediatric staff and equipments of the maternities. We used multiple regression techniques to study the specific effect of each parameter, while controlling effects of age and parity of the mothers. We have found that even on the low risk samples, variation of rates were important. The type of on-call, the level of pediatric services and the architecture of maternities exerted a strong and significant effect on the rate of cesarean sections compared to the absence of impact of the number of deliveries. We discuss the reasons why, explaining the occurrence of those factors and then, stress the need to take into account the relevant factors for organizational audits. It appears that, in the context of the new regulation of the health system, these results should give obstetricians reasons to enhance their efforts to correct inefficient practices and to respect consensual guidelines and joint accreditation of obstetric and pediatric units.
