Risk factors for return visits and rehospitalizations to the child emergency psychiatric unit: A retrospective study over 2 years at Saint-Étienne University Hospital.

PURPOSE: This retrospective study aimed to achieve a better understanding of risk factors leading children and adolescents hospitalized in an emergency psychiatric ward to return visits, and to propose preventive devices. METHOD: From January 2, 2010 through February 29, 2012, 180 children and adolescents younger than 17 years were hospitalized in a total of 261 stays in the emergency psychiatric ward of University hospital of Saint-Étienne (France). We assessed clinical and sociodemographic characteristics of these patients and traced any of their return visits to the same unit through December 31, 2012. Risk factors for patients' repeated visits were calculated using multivariate analysis, and the cumulative incidence of returns using the Kaplan-Meier method for censored data. We used confidence interval of relative risk, considering 0.05 to reflect significance. RESULTS: Over the 2 years of the study, 77 (42.8%) of the 180 patients revisited the emergency psychiatric ward; 62 (80.7%) of these required further hospitalizations. Multivariate analysis linked the patients' psychiatric history (RR=2.5) and pursuit of vocational education (RR=4) with the risk of return. Return visits rose from 27.2% at 6 months to 41.2% at 2 years. CONCLUSION: Knowledge of risk factors would allow implementation of secondary or tertiary preventive devices. Students could undergo early screening of psychiatric pathologies using mobile screening teams which would save money, avoid hospitalizations, and when necessary, facilitate both hospitalization and return visits.

Second malignant neoplasm following childhood cancer: A nested case-control study of a recent cohort (1987-2004) from the Childhood Cancer Registry of the Rhône-Alpes region in France.

From a population-based cohort of cases of first cancers diagnosed between 1987 and 2004, before the patient's age of 15 years, the authors conducted a nested case-control study, matching 64 patients who experienced a second malignant neoplasm (SMN) with 190 controls. SMNs comprised 10 leukemia or myelodysplastic syndromes, 5 lymphomas induced by Epstein-Barr virus after allograft, and 49 solid tumors, including mainly 25 carcinomas (17 of the thyroid), 9 bone sarcomas, and 7 central nervous system (CNS) tumors. The median latency occurrence was 6.5 years, and that of thyroid carcinomas induced by 12 Gy fractioned total body irradiation (TBI) was 7.6 years. The relative risk (RR) of an SMN was increased by genetic and family factors and increased 17 to 69 times according to the dose of radiotherapy administered in the region for the first cancer. Age younger than 4 years at the time of radiotherapy increased the risk of SMN. Chemotherapy adjusted according to the dose of radiotherapy administered in the field yielded a greater RR of an SMN only for cumulative doses exceeding 2 g/m2 of epipodophyllotoxin but not for alkylating agents or platinum compounds. The RR of secondary leukemia increased 10-fold following high doses of epipodophyllotoxin >2 g/m2 but was not affected by alkylating agents or anthracyclines. The crude RR of a solid SMN developing after radiotherapy was very high at 18 and reached 90.7 for thyroid carcinoma after TBI, whereas the authors observed no increased risk associated with chemotherapy. These results confirm the risk of secondary leukemia after epipodophyllotoxin and of solid tumor after radiotherapy.

Psychiatric disorders in 130 survivors of childhood cancer: preliminary results of a semi-standardized interview.

BACKGROUND: Although psychological sequelae are well known among survivors of childhood cancer, psychiatric sequelae remain inadequately explored. Long-term psychiatric sequelae and their main risk factors in this population were evaluated. PROCEDURE: Initially, 483 survivors of childhood cancer, except leukemia, were invited to complete a questionnaire assessing their health and quality of life. Of them, 130 completed the survey, subsequently consulted with a pediatric oncologist and an internist, and met with a psychologist for a semi-standardized interview based on the Mini International Neuropsychiatric Interview (MINI), which allowed diagnosis of DSM-IV Axis 1 psychiatric disorders. The collected data were compared with those of the French general population. RESULTS: Seventy-three of the 130 survivors (56.2%) who completed the MINI interview reported experiencing at least one psychiatric disorder since cancer diagnosis, mostly anxiety (39.2%), mood (27.7%), or major depressive (24.6%) disorders; 46 reported at least one current disorder (35.4%). Agoraphobia (P = 0.02) and psychotic disorders were more common (P = 0.003) and general anxiety disorder less common (P < 0.001) among survivors than the general population. Most disorders correlated significantly with survivors' ratings of lower quality of life. Smoking, cancer type, and treatments significantly influenced the prevalence of psychiatric disorders. CONCLUSIONS: Results were consistent between the self-questionnaire and MINI interview responses, though time may have biased memory. Vulnerability to and high risk for developing DSM-IV Axis 1 psychiatric disorders of childhood cancer survivors can persist long after diagnosis and treatment. Thus, systematic and general psychological screening of survivors may facilitate long-term psychological restoration.

[Critical analysis of French DRG based information system (PMSI) databases for the epidemiology of cancer: a longitudinal approach becomes possible]. / Analyse critique des données du PMSI pour l'épidémiologie des cancers : une approche longitudinale devient possible.

BACKGROUND: Use of French Diagnosis Related Groups (DRGs) program databases, apart from financial purposes, has recently been improved since a unique anonymous patient identification number has been created for each inpatient in administrative case mix database. Based on the work of the group for cancer epidemiological observation in the Rhône-Alpes area, (ONC-EPI group), we review the remaining difficulties in the use of DRG data for epidemiological purposes and we consider a longitudinal approach based on analysis of database over several years. We also discuss limitations of this approach. DIFFICULTIES: The main problems are related to a lack of quality of administrative data, especially coding of diagnoses. These errors come from missing or inappropriate codes, or not being in accordance with prioritization rules (causing an over- or under-reporting or inconsistencies in coding over time). One difficulty, partly due to the hierarchy of coding and the type of cancer, is the choice of an extraction algorithm. In two studies designed to estimate the incidence of cancer cared in hospitals (breast, colon-rectum, kidney, ovaries), a first algorithm, including a code of cancer as principal diagnosis with a selection of surgical procedures less performed than the second one including a code of cancer as principal diagnosis only, for which the number of hospitalizations per patient ratio was stable across time and space. The chaining over several years allows, by tracing the trajectory of the patient, to detect and correct inaccuracies, errors and missing values, and for incidence studies, to correct incident cases by removing prevalent cases. DISCUSSION: However, linkage, complete only since 2007, does not correct data in all cases. Ways of future improvement certainly pass through improved algorithms for case identification and especially by linking DRG data with other databases.

[ICD-10 adaptation of 15 Agency for Healthcare Research and Quality patient safety indicators]. / Adaptation au codage CIM-10 de 15 indicateurs de la sécurité des patients proposés par l'Agence étasunienne pour la recherche et la qualité des soins de santé (AHRQ).

BACKGROUND: In the United States, the Agency for Healthcare Research and Quality (AHRQ) has developed 20 Patient Safety Indicators (PSIs) to measure the occurrence of hospital adverse events from medico-administrative data coded according to the ninth revision of the international classification of disease (ICD-9-CM). The adaptation of these PSIs to the WHO version of ICD-10 was carried out by an international consortium. METHODS: Two independent teams transcoded ICD-9-CM diagnosis codes proposed by the AHRQ into ICD-10-WHO. Using a Delphi process, experts from six countries evaluated each code independently, stating whether it was "included", "excluded" or "uncertain". During a two-day meeting, the experts then discussed the codes that had not obtained a consensus, and the additional codes proposed. RESULTS: Fifteen PSIs were adapted. Among the 2569 proposed diagnosis codes, 1775 were unanimously adopted straightaway. The 794 remaining codes and 2541 additional codes were discussed. Three documents were prepared: (1) a list of ICD-10-WHO codes for the 15 adapted PSIs; (2) recommendations to the AHRQ for the improvement of the nosological frame and the coding of PSI with ICD-9-CM; (3) recommendations to the WHO to improve ICD-10. CONCLUSIONS: This work allows international comparisons of PSIs among the countries using ICD-10. Nevertheless, these PSIs must still be evaluated further before being broadly used.

[Clinical path and life quality of women under 75 years with an urinary incontinence relevant to surgical treatment]. / Parcours de soins et qualité de vie des femmes de moins de 75 ans relevant d'une prise en charge chirurgicale pour incontinence urinaire.

OBJECTIVES: Urinary incontinence has a high prevalence and a significant impact on quality of life, especially for women. Surgery is possible after failure of lifestyle changes, physiotherapy. Analyzing the care pathway of women under 75 years of age who have undergone surgery for urinary incontinence in link with recommendation and suggest possible improvements. METHODS: Quantitative, multicentric, retrospective survey carried out between 10/09/2019 and 25/11/2019, based on anonymous self-report questionnaire, among women aged between 32 and 75 and operated in different hospitals in Loire (France). RESULTS: Ninety-three answers were exploited out of 204. Among the women, 49.5 % had stress, 50.5 % mixed incontinence. Before the intervention, it had evolved for 5 years on average and caused discomfort evaluated at an average 7.5/10. Eighty percent frequently used protective pads and bladder training. Lifestyle changes and the voiding diary were not used much. Eighty-six percent of women felt comfortable to speak to a physician. Seventy-three percent had performed a urodynamic test, 47 % an abdominal ultrasound and 40 % a urinalysis. Seventy-seven percent performed physiotherapy, 39 % self-administered physiotherapy, 7 % used medication. The postoperative quality of life was evaluated at 7.8/10; 58 % felt healed and 69 % considered their sex life had improved. CONCLUSIONS: The care pathway could be improved through systematic screening for urinary incontinence and its impact. The development of a care plan to coordinate and propose quick care could help patients to improve their life.

[Long term mortality of five-year survivors of childhood cancer in Rhône-Alpes region]. / Mortalité tardive après cancer des enfants survivants à cinq ans dans la région Rhône-Alpes.

BACKGROUND: The population of survivors of childhood cancer is currently growing. Studies from other countries have shown an increased risk of late mortality. In order to measure this risk within a French cohort, the mortality of children who had survived five years from a cancer diagnosis were compared to the mortality of the general population, according to follow-up interval and cancer and treatment characteristics. METHODS: The study population consisted of 635 children diagnosed with cancer before the age of 15 who had survived at least five years, and were registered in the Rhone-Alpes region cancer registry from 1987 to 1992. Mortality was compared with general population rates of the Rhone-Alpes region to assess age and sex standardized mortality ratio (SMR) and absolute excess risk of death. RESULTS: The median follow-up of children was 14.0 years. Among the 42 observed deaths, 71.4% were attributed to a recurrence of the original cancer, 9.5% to a second cancer. The 15-year cumulative risk of death, all causes, was 7.1%. The overall mortality of the cohort was 20.7 fold greater than the general population (95% CI: 14.9-27.9), and the absolute excess risk of 6.9 per 1000 persons-years. The long term excess-mortality was higher in case of recurrence of original cancer (SMR=99.9, 95% CI: 67.9-141.9, absolute excess risk 35.4 per 1000 persons-years); it was raised during the five to nine years follow-up interval after diagnosis (SMR=33.8, 95% CI: 23.2-47.3) mainly due to the primary malignancy, and decreased after (10-14 years follow-up interval SMR=6.5, 95% IC 2.4-14.2). CONCLUSION: The late mortality of childhood cancer is significantly increased during the five to nine years following diagnosis and decreases after, but the cohort follow-up has to be extended in order to assess outcome beyond 15 years after diagnosis.

[Quality and usefulness of an anonymous unique personal identifier to link hospital stays recorded in French claims databases]. / Qualité et utilité d'un identifiant patient anonyme et unique pour le chaînage des séjours hospitaliers dans les bases de données médicoéconomiques françaises.

BACKGROUND: Since 2001, the French national case mix program is allowed by law to use an enciphering algorithm named "FOIN" to produce a unique anonymous identifier in order to crosslink, within and across hospitals, discharge abstracts from a given patient. This algorithm "thrashes" the person's health insurance number, date of birth and gender. Before using information produced by the case mix program, either for case mix payment or for epidemiology research or for assessing care approaches, the quality of linkage must be evaluated. METHODS: Foin error flags were first assessed in the 2002 Rhône-Alpes regional case mix database. Second, for the two university hospitals of Lyon and Saint-Etienne, double identifiers (two or more Foin identifiers for the same patient) and collisions (a single Foin identifier for at least two patients) were compared with others identifiers: administrative identifier and an anonymous identifier produced by Anonymat software from name, forename and date of birth. Third, Foin error flags are crossed with Foin double identifier or collision mistakes. RESULTS: First, among 1,668,971 hospital discharge abstracts from the regional case mix database, 206,710 (12.4%) had at least one Foin error flag. The most frequent error flag (93026 [5.5%] stays) was due to the lack of the three identifying variables. The greatest number for error flags concerned the stays of newborns (38.5%) and those of public hospitals (17.3%). Second, Foin created a few double identifiers: 1.2% among 137,236 patients from university hospital of Lyon and 0.3% among 39512 patients from university hospital of Saint-Etienne. The collisions concerned 7776 (5.7%) patients from Lyon and 460 (1.2%) from Saint-Etienne. The identifier produced by Anonymat performed better than the one produced by Foin: 99.6% from the two university hospitals. Third, less than 3% of stays without Foin error flag nevertheless had mistakes on Foin when compared with others identifiers. CONCLUSION: The overall assessment is not in favour of a quality threshold using the Foin identifier on a routine basis except in some areas and if certain activities like neonatology are excluded. There are several ways to improve the linkage of health data.

Blood parameters of preterm neonates: postnatal evolution according to gestational age.

INTRODUCTION: The blood count provides qualitative and quantitative essential information on bloodlines. Reference hematologic parameters have been established in children and neonates, but few data are available regarding the premature population during the first month of life. The main objective of this study was to establish normative values for blood parameters for premature infants born between 26 and <37 weeks of gestation, during the first month of life, taking into account gestational and postnatal age and treatments that can impact the threshold values. METHODS: A single-center retrospective study was conducted based on the clinical and laboratory data of preterm infants born between January 1, 2012 and December 31, 2013 and hospitalized in the intensive care, neonatal, and maternity units of University Hospital of Saint Etienne (France). Data were collected by crossing the PMSI database (date of birth and gestational age), the administrative patient database (IPP), and the pre-analytical laboratory database. Anthropometric and clinical data were extracted for both mother and child. The samples were all made from central or peripheral venous blood. All blood parameters were taken into account. RESULTS: The degree of prematurity is a factor greatly influencing the values of the blood parameters at birth. All three blood lines increase in proportion to gestational age. We were able to highlight for some blood parameters specific kinetic profiles according to gestational age. CONCLUSION: Blood parameters of preterm neonates depend on both the degree of prematurity, postnatal age, and perinatal treatments. A good knowledge of these physiological variations may help target transfusion or therapeutic indications in everyday practice.

[Childhood cancer incidence and survival rates in the Rhône-Alpes regional paediatric registry 1987-1999]. / Les cancers de l'enfant de la région Rhône-Alpes: incidence et survie 1987-1999.

UNLABELLED: Cancer is rare in children, and pediatric malignancies represent only 1% of all cancers. OBJECTIVES: The cure rate is high and increasing, and ongoing data collection is therefore warranted. MATERIALS AND METHODS: Here we report the incidence and survival rates of childhood cancers between 1987 and 1999 in the Rhône-Alpes region of France. RESULTS: A total of 1945 cases were recorded during the study period, with an average of 149.6 new cases per year. The approximate incidence rate was 134.1/10(6) per year and the age-standardized incidence rate was 139.2/10(6) per year. The histological distribution and 5-year survival rates were respectively 30.2 and 73% for leukemia, 12.3 and 91.6% for lymphoma, 24.7 and 60.1% for CNS tumors, 9.1 and 71.1% for neuroblastoma, 2.5 and 94.1% for retinoblastoma, 5.8% and 89.9% for renal tumors, 1 and 75% for liver tumors, 6.1 and 60.9% for bone tumors, 4.1 and 58.6% for soft-tissue tumors, 1.1 and 71% for germ cell tumors, and 2.4 and 85.1% for carcinomas. CONCLUSION: The overall survival rate was 75%. Long-term treatment complications warrant further studies of children who survive into adulthood.

[Adverse drug reactions in children: 10 years of pharmacovigilance]. / Effets indésirables médicamenteux chez l'enfant : 10ans de pharmacovigilance.

BACKGROUND: Knowledge of drug tolerance and safety in children is limited. The study of spontaneous notifications of adverse events (AEs) can be an important source of information. OBJECTIVE: Describe the characteristics of drug adverse effects (DAEs) in children 0-17 years of age reported to the pharmacovigilance center of Saint-Étienne in 2004-2013. METHODS: This retrospective descriptive study was conducted based on DAE notifications, classified according to age, sex, severity of organ affected (using classification by the System organ class [SOC]) and by suspected drug (Anatomical therapeutic chemical [ATC] drugs). RESULTS: A total of 371 notifications were analyzed. The male:female ratio was 1. Serious cases accounted for 36%, of which 73% resulted in hospitalization or prolongation of hospitalization. The most frequent DAEs were cutaneous (21.1%), infection (13.5%) and general (11.5%). The most frequently involved therapeutic classes were anti-infectives for systemic use (38.7%), mainly vaccines and antibiotics, as well as antineoplastic and immunomodulatory therapy (19.2%) and drugs acting on the nervous system (12.5%). CONCLUSIONS: The analysis of notifications of adverse drug reactions is an important source of information and is underutilized in pediatrics. The data from this study confirm those of European databases with spontaneous reporting. The majority of anti-infectives including antibiotics raises the question of the proper use of this class in this population. Larger studies focused on the drugs at risk would improve the knowledge and safe use of medicines in children.

[An epidemiological study of early consultations of newborns in pediatric emergency units]. / Étude épidémiologique des consultations précoces de nouveau-nés aux services d'accueil des urgences pédiatriques.

BACKGROUND: The number of visits to the pediatric emergency services has increased in the past 20 years in France and around the world, especially for neonates (under 28 days of age). OBJECTIVES: Determine for neonates the reasons requiring medical consultation in the emergency pediatric unit of Saint-Etienne University Hospital (France) and isolate the proportion of "non-urgent" preventable consultations that could be managed outside of emergency units. METHOD: Epidemiological, retrospective study on computerized data on neonates who were referred to the pediatric emergency unit of the Saint-Étienne University Hospital from 1 January to 31 December 2011. Four composite criteria "child not addressed by a healthcare professional; severity score G1, G2, G3 based on an internal scale; no further review undertaken; and return home" were used to define "non-urgent" consultations. RESULTS: A total of 419 infants were included in the study. The leading reasons for consultations were crying (14.1%), vomiting (11.9%), chest tightness (10.7%), fever (8.1%), and diarrhea (7%). The main diagnoses were acute nasopharyngitis (11.5%), gastroesophageal reflux (10%), colic (8.1%), and excessive parental anxiety (7.6%). The percentage of "non-urgent" consultations was 52.4%. CONCLUSIONS: Final diagnoses are quite similar to the reasons for consultation. The baby's unexplained crying and the inexperience of young parents resulted in an irrational anxiety. This study highlights the need for parental support at home after discharge from the maternity ward and the use of large-scale educational initiatives.

GALEN: a third generation terminology tool to support a multipurpose national coding system for surgical procedures.

Generalised architecture for languages, encyclopedia and nomenclatures in medicine (GALEN) has developed a new generation of terminology tools based on a language independent model describing the semantics and allowing computer processing and multiple reuses as well as natural language understanding systems applications to facilitate the sharing and maintaining of consistent medical knowledge. During the European Union 4 Th. framework program project GALEN-IN-USE and later on within two contracts with the national health authorities we applied the modelling and the tools to the development of a new multipurpose coding system for surgical procedures named CCAM in a minority language country, France. On one hand, we contributed to a language independent knowledge repository and multilingual semantic dictionaries for multicultural Europe. On the other hand, we support the traditional process for creating a new coding system in medicine which is very much labour consuming by artificial intelligence tools using a medically oriented recursive ontology and natural language processing. We used an integrated software named CLAW (for classification workbench) to process French professional medical language rubrics produced by the national colleges of surgeons domain experts into intermediate dissections and to the Grail reference ontology model representation. From this language independent concept model representation, on one hand, we generate with the LNAT natural language generator controlled French natural language to support the finalization of the linguistic labels (first generation) in relation with the meanings of the conceptual system structure. On the other hand, the Claw classification manager proves to be very powerful to retrieve the initial domain experts rubrics list with different categories of concepts (second generation) within a semantic structured representation (third generation) bridge to the electronic patient record detailed terminology.

Galen-In-Use: using artificial intelligence terminology tools to improve the linguistic coherence of a national coding system for surgical procedures.

GALEN has developed a language independent common reference model based on a medically oriented ontology and practical tools and techniques for managing healthcare terminology including natural language processing. GALEN-IN-USE is the current phase which applied the modelling and the tools to the development or the updating of coding systems for surgical procedures in different national coding centers co-operating within the European Federation of Coding Centre (EFCC) to create a language independent knowledge repository for multicultural Europe. We used an integrated set of artificial intelligence terminology tools named CLAssification Manager workbench to process French professional medical language rubrics into intermediate dissections and to the Grail reference ontology model representation. From this language independent concept model representation we generate controlled French natural language. The French national coding centre is then able to retrieve the initial professional rubrics with different categories of concepts, to compare the professional language proposed by expert clinicians to the French generated controlled vocabulary and to finalize the linguistic labels of the coding system in relation with the meanings of the conceptual system structure.

Galen-In-Use: an EU Project applied to the development of a new national coding system for surgical procedures: NCAM.

GALEN has developed a language independent common reference model based on a medically oriented ontology and practical tools and techniques for managing healthcare terminology including natural language processing. GALEN-IN-USE is the current phase which applied the modelling and the tools to the development or the updating of coding systems for surgical procedures in different national coding centre co-operating within the European Federation of Coding Centre (EFCC) to create a multilingual knowledge repository for multicultural Europe. NCAM (Nomenclature Commune des Actes Médicaux) is the new French multipurpose coding system for surgical procedures. The labels are processed from the intermediate dissections to the Grail representation and the natural language generation by the electronically related Medical Informatics research centres network of Saint Etienne, Manchester, Geneva and Nijmegen. The national coding centre is able to retrieve the initial labels with different categories of concepts, to compare the professional language proposed by expert clinicians to the French generated controlled vocabulary and to finalize the linguistic labels of the coding system in relation with the meanings of the conceptual system structure.

Galen: a third generation terminology tool to support a multipurpose national coding system for surgical procedures.

GALEN has developed a new generation of terminology tools based on a language independent concept reference model using a compositional formalism allowing computer processing and multiple reuses.

[A community approach to health of young children in the three rural cantons of Monts du Forez]. / Une approche communautaire de la santé des jeunes enfants dans trois cantons ruraux des Monts du Forez.

Recently a survey was done on the health of 0 to 6 year old children living in three rural districts within the Loire departement (Boen, Noirétable, St George en Couzan), from 1991 to 1995. Literature review, interview of professionals and families provide information regarding the children's state of health and the main factors influencing it. Even though it appears that the families cope with somatic diseases until the child is two, subsequent child behavior disorders problems are not properly addressed. Similarly difficulties are encountered in the field of prevention. The social, demographic and economic context, a deficient or inadequate health service network, the lack of day care centre are all factors that can explain the reported isolation and its impact on the child development and socialization. This report enabled actions to be prioritized, whose a partnership between a local association and maternal-child health centers to provide solutions to isolation.

[Initiation of breastfeeding and early weaning: a prospective study of the health perinatal network Loire-Nord Ardèche]. / Initiation de l'allaitement maternel et sevrage précoce: étude prospective du réseau périnatalité Loire-Nord Ardèche.

OBJECTIVES: The World Health Organization recommends exclusive breastfeeding of infants up to 6months. The proportion of breastfeeding initiation and duration increased more slowly in France than in neighboring European countries. The perinatal network data are incomplete. The objective of this study is to evaluate within the perinatal network "Loire-Nord Ardèche" (ELENA), breastfeeding rates in hospital discharge and at 2months, and identify needs for maternal support. PATIENTS AND METHODS: Prospective and declarative study by written questionnaire, with all the women volunteers who gave birth in October 2011 in a maternity of our perinatal network. RESULTS: Population concerns 426 women volunteers of 968 new mothers. Two hundred and ninety-four questionnaires were used: 69% of women initiated breastfeeding, 63% have continued after the stay in the maternity and 50% at 2 months. Eighty percent chose to breastfeed before pregnancy, mainly for child health, 65% with the support of their spouse, 58% if their mother had breastfed. Simple pathologies of breastfeeding and childbirth were responsible for weaning. A third of women in difficulty have not consulted anyone, one third wanted more practical help and systematic support motherhood. DISCUSSION AND CONCLUSION: The rate of initiation of breastfeeding or duration and the great influence of the surroundings of the mother, similar in this study to literature data, call for enhanced prenatal information for parents and systematic "lactation" consultation in the early post-partum, by trained professionals and with the help of support associations for breastfeeding. This study showed a clear need to support breastfeeding. It has also allowed targeting actions that would be able to avoid the majority of early weaning.

Identifying prevalent cases of breast cancer in the French case-mix databases.

OBJECTIVES: Little is known about cancer prevalence due to a lack of systematic recording of cancer patient follow-up data. To estimate the annual hospital prevalence of breast cancer in the general population of the Isère department (1.1 million inhabitants) in the Rhône-Alpes region, the second largest region in France (6 million inhabitants), we used the inpatient case-mix data, available in most European countries, to develop a method of cancer case identification. METHODS: A selection process was applied to the acute care hospital datasets among women aged 18 years or older, living in the Isère department and treated for breast cancer between 2004 and 2007. The first step in case selection was based on the national anonymous unique patient identifier. The second step consisted of retrieving all hospital stays for each case. The third step was designed to detect inconsistencies in the coding of the primary localization. An algorithm based on ICD-10 code for the hospital admission diagnosis was used to rule out hospitalizations unrelated to breast cancer. Five possible models for estimating prevalence were created combining selection steps with the admission diagnosis algorithm. RESULTS: Hospital prevalence over the four-year period varied from 6073 breast cancer cases for the simplest model (first selection step without the admission diagnosis algorithm) to 4951 when the first selection step was associated with the breast cancer code as admission diagnosis. The model combining the third selection step with a breast cancer-specific admission reason provided 5275 prevalent cases. CONCLUSION: The last model seems more appropriate for case-mix-data coding. Selecting admission diagnosis improved specificity. Combining all hospital stays for each patient has improved diagnostic sensitivity.
