Ultra-fast remote up-titration of heart failure treatment: a safe, efficient and feasible protocol

Introduction

Heart failure (HF) is a common disease with a significant economic burden, mainly caused by HF hospitalisations and significant morbi-mortality. Nevertheless, HF patients are still undertreated due to a clinical inertia that needs to be reversed as soon as possible using new, safe and available methods. Remote up-titrating HF medication might be the solution to rapidly optimize HF treatment to maximal tolerated doses.

Purpose

Our objective was to describe the safety, efficacy and feasibility of an ultra-fast remote up-titration protocol of HF treatment.

Methods

Patients with a recent hospitalization due to a HF decompensation and left ventricular ejection fraction <50% were retrospectively included in our database. We collected clinical, biological and treatment data at enrollment and at the end of HF medication optimization. Our protocol consisted in remote consultation (via telephone or video-consultation) every 15 days with a 72h prior blood test. Blood pressure (BP), heart rate (HR) and weight were recorded either by tele-monitoring or self-measurement.

Results

We evaluated 96 patients, 25% female with a mean LVEF at 29%, main etiology of HF was ischemic (48%) and mean NTproBNP was 2384 pg/mL. Mean BP was 112/70 mmHg, HR was 73 bpm, glomerular filtration rate (GFR) 71 ml/min and potassium concentration was 4,4 mEq/L. Ninety four patients were initially treated with a beta blocker (BB), 29% of our cohort was treated either with an angiotensin-converting enzyme inhibitor (ACEI) or an angiotensin receptor blocker (ARB) and 59% was treated with angiotensin receptor neprilysin inhibitor (ARNI). A total of 72 patients were treated with a mineralocorticoid receptor antagonist (MRA) and 58 patients were also treated with an inhibitor of sodium-glucose transport protein 2 (SLGT2i), Figure 1. Median duration of tele-titration consultation was 42 days. We up-titrated BB in 50% of our patients, of which 10% were at maximum dose, making a total of 98% of our cohort under BB treatment. Sixty percent of patients under ACEI or ARB were switched to ARNI. Of the 82% of patients under ARNI, up to 50% achieved the maximal dose.

We introduced or up-titrated ARM in 41 patients, reaching the target dose in 37%. Dose variations and mean initial and final doses are shown in Figure 2.1 and 2.2

Minor adverse events that motivated a down-titration or a cessation of treatment were, hyperkalemia 5%, acute renal failure (ARF) 6%, hypotension 3% and bradycardia 2%. Non urgent hospitalization due to ARF with hyperkalemia or HF only occurred in 2 cases.

The limiting factors for not reaching the optimal targeted dose were low HR in 20%, hypotension in 11%, high concentration of potassium 10% and chronic renal failure in 9%.

Conclusion

Remote up-titration of HF medication is a promising tool in the fight against clinical inertia and a fast, feasible, safe (only 2% of major events) and efficient solution to our undertreated patients.

Benefits of interventional telemonitoring in patients with chronic heart failure

Background

The aim of this study was to assess the effect of interventional specialized Telemonitoring (ITM) compared to standard telemonitoring (STM) and standard of care (SC) on preventing all causes of death, cardiovascular mortality and unplanned hospitalization in heart failure (HF) patients.

Methods and results

414 HF-patients derived from two French cohorts (OSICAT and ETAPES) were included in this study, and subsequently randomized into three groups ITM-group (n=220), STM-group (n=99) and SC-group (n=95). The telemonitoring was performed by the specialized HF-cardiology staff at a university hospital. During the mean follow-up period of 344 days, there were significantly fewer primary endpoints like unplanned hospitalization (13.6% vs 34.3% vs 36.8%, p<0.05), all-cause of death (4.5% vs 20.2% vs 16.8%, p<0.05) and cardiovascular mortality (3.2% vs 15.2% vs 8.4%, p<0.05) in the ITM-group. The multivariate logistic regression revealed a significant negative association between the ITM and unplanned hospitalization (OR=0.293 95% CI [0.160–0.535], p<0.05) and all-cause of death (OR=0.243 95% CI [0.099–0.596], p=0.002), respectively. Kaplan Meier and log rank test showed significant difference in median event-free survival in favor of ITM-group.

Conclusions

Using ITM to follow-up HF-patients results in reducing the rate of unplanned hospitalization and all cause of death.

The emergence, spread and vanishing of a French SARS-CoV-2 variant exemplifies the fate of RNA virus epidemics and obeys the Mistigri rule

The nature and dynamics of mutations associated with the emergence, spread, and vanishing of SARS-CoV-2 variants causing successive waves are complex. We determined the kinetics of the most common French variant ("Marseille-4") for 10 months since its onset in July 2020. Here, we analyzed and classified into subvariants and lineages 7453 genomes obtained by next-generation sequencing. We identified two subvariants, Marseille-4A, which contains 22 different lineages of at least 50 genomes, and Marseille-4B. Their average lifetime was 4.1 ± 1.4 months, during which 4.1 ± 2.6 mutations accumulated. Growth rate was 0.079 ± 0.045, varying from 0.010 to 0.173. Most of the lineages exhibited a bell-shaped distribution. Several beneficial mutations at unpredicted sites initiated a new outbreak, while the accumulation of other mutations resulted in more viral heterogenicity, increased diversity and vanishing of the lineages. Marseille-4B emerged when the other Marseille-4 lineages vanished. Its ORF8 gene was knocked out by a stop codon, as reported in SARS-CoV-2 of mink and in the Alpha variant. This subvariant was associated with increased hospitalization and death rates, suggesting that ORF8 is a nonvirulence gene. We speculate that the observed heterogenicity of a lineage may predict the end of the outbreak.

Culture and identification of a "Deltamicron" SARS-CoV-2 in a three cases cluster in southern France

Multiple SARS-CoV-2 variants have successively, or concomitantly spread worldwide since the summer of 2020. A few co-infections with different variants were reported and genetic recombinations, common among coronaviruses, were reported or suspected based on co-detection of signature mutations of different variants in a given genome. Here we report three infections in southern France with a Delta 21J_AY.4-Omicron 21K/BA.1 "Deltamicron" recombinant. The hybrid genome harbors signature mutations of the two lineages, supported by a mean sequencing depth of 1163-1421 reads and a mean nucleotide diversity of 0.1%-0.6%. It is composed of the near full-length spike gene (from codons 156-179) of an Omicron 21K/BA.1 variant in a Delta 21J/AY.4 lineage backbone. Importantly, we cultured an isolate of this recombinant and sequenced its genome. It was observed by scanning electron microscopy. As it is misidentified with current variant screening quantitative polymerase chain reaction (qPCR), we designed and implemented for routine diagnosis a specific duplex qPCR. Finally, structural analysis of the recombinant spike suggested its hybrid content could optimize viral binding to the host cell membrane. These findings prompt further studies of the virological, epidemiological, and clinical features of this recombinant.

Characteristics of the first 1,119 SARS‐CoV‐2 Omicron variant cases, in Marseille, France, November‐December 2021

One thousand one hundred and nineteen cases of severe acute respiratory syndrome coronavirus 2 (SARS‐CoV‐2) Omicron variant cases have been diagnosed at the Institut Hospitalo‐Universitaire Méditerranée Infection, Marseille, France, between November 28, 2021, and December 31, 2021. Among the 825 patients with known vaccination status, 383 (46.4%) were vaccinated, of whom 91.9% had received at least two doses of the vaccine. Interestingly, 26.3% of cases developed SARS‐CoV‐2 infection within 21 days following the last dose of vaccine suggesting possible early production of anti‐SARS‐CoV‐2 facilitating antibodies. Twenty‐one patients have been hospitalized, one patient required intensive care, and another patient who received a vaccine booster dose died.

Significantly low rates of hospitalization, transfer to Intensive Care Unit and death were observed in patients infected with Omicron as compared to those infected with Delta variant of severe acute respiratory syndrome coronavirus 2 during the same period,

26.3% of patients infected with Omicron get infected during the 3 weeks following COVID‐19 vaccination raising the question of facilitating antibodies.

Natural History of Perianal Fistulising Lesions in Patients With Elderly-onset Crohn's Disease: A Population-based Study

INTRODUCTION

Most studies of elderly-onset Crohn's disease [CD; diagnosed in patients aged 60 or over] have described a mild course. However, data on the natural history of perianal fistulising CD [pfCD] in this population are scarce. In a population-based cohort study, we described the prevalence, natural history, and treatment of pfCD in patients with elderly-onset CD vs patients with paediatric-onset CD.

METHOD

All patients diagnosed with CD at or after the age of 60 between 1988 and 2006, were included [n = 372]. Logistic regression, Cox models, and a nested case-control method were used to identify factors associated with pfCD.

RESULTS

A total of 34 elderly patients [9% of the 372] had pfCD at diagnosis. After a median follow-up of 6 years (interquartile range [IQR]: 3; 10), 59 patients [16%] had pfCD; the same prevalence [16%] was observed in paediatric-onset patients. At last follow-up, anal incontinence was more frequent in elderly patients with pfCD than in elderly patients without pfCD [22% vs 4%, respectively; p < 10-4]. Rectal CD at diagnosis was associated with pfCD: hazard ratio (95% confidence interval [CI] = 2.8 [1.6-5.0]). Although 37% of the patients received immunosuppressants and 17% received anti-tumour necrosis factor agents, 24% [14 out of 59] had a definitive stoma at last follow-up.

CONCLUSION

During the first 6 years of disease, the prevalence of pfCD was similar in elderly and paediatric patients. Rectal involvement was associated with the appearance of pfCD in elderly-onset patients. Around a quarter of patients with elderly-onset CD will have a stoma. Our results suggest that treatment with biologics should be evaluated in these patients.

P3360Quantitative assessment of tricuspid regurgitation using right and left ventricular stroke volumes obtained from tomographic equilibrium radionuclide ventriculography

Background

Quantitative assessment of valve regurgitation using volumetric method by comparing right and left ventricular stroke volumes is still under investigations.

Aims

To investigate the accuracy of tomographic equilibrium radionuclide ventriculography (t-ERV) for the quantification of tricuspid regurgitation (TR).

Methods and results

Sixty-one patients (44 men; mean age 59±12 years) who underwent both t-ERV and transthoracic echocardiography (TTE) studies within 2 weeks for right ventricular systolic function assessment were eligible for inclusion. A sub-group of 22 patients underwent both t-ERV and CMR. Patients with mitral/aortic regurgitation by TTE were excluded of the study. TR regurgitant volume (RVol) was calculated using the proximal isovelocity surface area (PISA) method from TTE and the volumetric method (right ventricular stroke volume minus left ventricular stroke volume) from t-ERV. RVol tended to be higher using the ERV volumetric method as compared to PISA method (43±35 and 35±33 ml, respectively; P<0.0001). There was a significant correlation between RVol as assess by ERV and by TTE (R=0.95, P<0.0001). Intraclass correlation coefficient between TTE and ERV for TR quantification was 0.95 (P<0.0001). Among patients who underwent CMR, the correlation between RVol obtained by TTE and by t-ERV and CMR were R=0.81 and R=0.75, respectively (all P<0.0001), without difference between the two correlations (P=0.263).

Linear regression (left) and Bland-Altma

Conclusion

TR assessment using the t-ERV correlates well with PISA from TTE in patients referred for right ventricular systolic function assessment.

Noncontiguous finished genome sequence and description of Raoultibacter massiliensis gen. nov., sp. nov. and Raoultibacter timonensis sp. nov, two new bacterial species isolated from the human gut

As part of the culturomics project aiming at describing the human microbiota, we report in this study the description of the new bacterial genus Raoultibacter gen. nov. that includes two new species, that is, R. massiliensis sp. nov. and R. timonensis sp. nov. The R. massiliensis type strain Marseille-P2849T was isolated from the fecal specimen of a healthy 19-year-old Saudi Bedouin, while R. timonensis type strain Marseille-P3277T was isolated from the feces of an 11-year-old pygmy female living in Congo. Strain Marseille-P2849T exhibited 91.4% 16S rRNA sequence similarity with Gordonibacter urolithinfaciens, its phylogenetic closest neighbor with standing in nomenclature. As well, strain Marseille-P3277T exhibited 97.96% 16S rRNA similarity with strain Marseille-P2849T . Both strains were Gram-positive, motile, nonspore-forming rod and form transparent microcolonies on blood agar in both anaerobic and microaerophilic atmospheres. The genome sizes of strain Marseille-P2849T and strain Marseille-P3277T were 3,657,161 bp and 4,000,215 bp, respectively. Using a taxono-genomic approach combining the phenotypic, biochemical, and genomic characteristics, we propose the genus Raoultibacter gen. nov., which contains strains Marseille-P2849T (= CSUR P2849T , = DSM 103407T ) and Marseille-P3277T (=CCUG 70680T , =CSUR P3277T ) as type strains of the species R. massiliensis sp. nov., and R. timonensis sp. nov., respectively.

Deuxième niveau de compétence pour l’échographie clinique en médecine d’urgence. Recommandations de la Société française de médecine d’urgence par consensus formalisé

La Société française de médecine d’urgence a élaboré en 2016 des recommandations formalisées d’experts définissant le premier niveau de compétence en échographie clinique en médecine d’urgence. Ce niveau est maintenant complété par un deuxième niveau correspondant à une pratique plus avancée utilisant des techniques non envisagées dans le premier niveau comme l’utilisation du Doppler et nécessitant aussi une pratique et une formation plus poussées. Des champs déjà présents dans le premier référentiel sont complétés, et de nouveaux champs sont envisagés. La méthodologie utilisée est issue de la méthode « Recommandations par consensus formalisé » publiée par la Haute Autorité de santé et de la méthode Delphi pour quantifier l’accord professionnel. Ce choix a été fait devant l’insuffisance de littérature de fort niveau de preuve dans certaines thématiques et de l’existence de controverses. Ce document présente les items jugés appropriés et inappropriés par les cotateurs. Ces recommandations définissent un deuxième niveau de compétence en ECMU.

Study of crystal-field excitations and infrared active phonons in TbMnO3

The Tb³⁺ (4f ⁸) crystal-field (CF) excitations and the infrared phonons in TbMnO₃ are studied as a function of temperature and under an applied magnetic field. The phonon energy shifts reflect local displacement of the oxygen ions that contribute to the CF energy level shifts below 120 K and under magnetic field. The CF polarized transmission spectra provide interesting information about the debated nature of the excitations at 41, 65, 130 cm^-1. We also evaluate the contribution of the charge transfer mechanism to the magnetoelectric process in TbMnO₃ under magnetic field.

Dramatic Increase in Incidence of Ulcerative Colitis and Crohn's Disease (1988-2011): A Population-Based Study of French Adolescents

OBJECTIVES

Few data are available to describe the changes in incidence of pediatric-onset inflammatory bowel disease (IBD). The aim of this study was to describe changes in incidence and phenotypic presentation of pediatric-onset IBD in northern France during a 24-year period.

METHODS

Pediatric-onset IBD (<17 years) was issued from a population-based IBD study in France between 1988 and 2011. Age groups and digestive location were defined according to the Paris classification.

RESULTS

1,350 incident cases were recorded (8.3% of all IBD) including 990 Crohn's disease (CD), 326 ulcerative colitis (UC) and 34 IBD unclassified (IBDU). Median age at diagnosis was similar in CD (14.4 years (Q1=11.8-Q3=16.0)) and UC (14.0 years (11.0-16.0)) and did not change over time. There were significantly more males with CD (females/males=0.82) than UC (females/males=1.25) (P=0.0042). Median time between onset of symptoms and IBD diagnosis was consistently 3 months (1-6). Mean incidence was 4.4/10⁵ for IBD overall (3.2 for CD, 1.1 for UC and 0.1 for IBDU). From 1988-1990 to 2009-2011, a dramatic increase in incidences of both CD and UC were observed in adolescents (10-16 years): for CD from 4.2 to 9.5/10⁵ (+126%; P<0.001) and for UC, from 1.6 to 4.1/10⁵ (+156%; P<0.001). No modification in age or location at diagnosis was observed in either CD or UC.

CONCLUSIONS

In this population-based study, CD and UC incidences increased dramatically in adolescents across a 24-year span, suggesting that one or more strong environmental factors may predispose this population to IBD.

Extra-intestinal Manifestations at Diagnosis in Paediatric- and Elderly-onset Ulcerative Colitis are Associated With a More Severe Disease Outcome: A Population-based Study

BACKGROUND AND AIMS

Data on extra-intestinal manifestations [EIM] and their impact on the disease course of ulcerative colitis [UC] in population-based cohorts are scarce, particularly in paediatric- and elderly-onset UC patients. The aims of this population-based study were to assess: 1] the occurrence of EIM in paediatric- and elderly-onset UC; 2] the factors associated with EIM; and 3] their impact on long-term disease outcome.

METHODS

Paediatric-onset [< 17 years at diagnosis] and elderly-onset UC patients [> 60 years at diagnosis] from a French prospective population-based registry [EPIMAD] were included. Data on EIM and other clinical factors at diagnosis and at maximal follow-up were collected.

RESULTS

In all, 158 paediatric- and 470 elderly-onset patients were included [median age at diagnosis 14.5 and 68.8 years, median follow-up 11.2 and 6.2 years, respectively]. EIM occurred in 8.9% of childhood- and 3% of elderly-onset patients at diagnosis and in 16.7% and 2.2% of individuals during follow-up [p < 0.01], respectively. The most frequent EIM was joint involvement [15.8% of paediatric onset and 2.6% of elderly-onset]. Presence of EIM at diagnosis was associated with more severe disease course [need for immunosuppressants or biologic therapy or colectomy] in both paediatric- and elderly-onset UC (hazard ratio [HR] = 2.0, 95% confidence interval [CI]: 1.0-4.2; and HR = 2.8, 0.9-7.9, respectively). Extensive colitis was another independent risk factor in both age groups.

CONCLUSIONS

Elderly-onset UC patients had lower risk of EIM either at diagnosis or during follow-up than paediatric-onset individuals. EIM at diagnosis predicted more severe disease outcome, including need for immunosuppressive or biologic therapy or surgery, in both paediatric- and elderly-onset UC.

Raman and infrared study of 4f electron-phonon coupling in HoVO3

First-order Raman scattering and multiphonons are studied in RVO3 (R  =  Ho and Y) as a function of temperature in the orthorhombic and monoclinic phases. Raman spectra of HoVO3 and YVO3 unveil similar features since both compounds have nearly identical R-radii. However, the most important difference lies in the transition temperature involving the V(3+) orbitals, the V(3+) magnetic moments as well as the crystallographic structure. Particularly, the magnetic and orbital reorientations occur at T N2  =  40 K for HoVO3 instead T N2  =77 K in the case of YVO3. For both systems, anomalous phonon shifts which are related to spin-phonon coupling are observed below the V(3+) magnetic ordering temperature (T N1  ≈  110 K) while additional phonon anomalies are exclusively observed in HoVO3 around T (*)  ≈  15 K. On the other hand, infrared (IR) transmittance measurements as a function of temperature reveal Ho(3+5)I8  →  (5)I7 excitations and additional excitations assigned as vibronics. These latter combined with drastic changes in Ho(3+5)I8  →  (5)I7 excitations at T N2, are indicative of a strong coupling between the Ho(3+) ions and the ligand field. This could explain the large magnetocaloric capacity shown by HoVO3.

Lactobacillus bacteremia: Pathogen or prognostic marker?

OBJECTIVE

Lactobacillus bacteremia is a rare event and its epidemiology is poorly known. Whether Lactobacillus bacteremia is a contaminant, a risk factor, or a risk marker of death remains an open question.

PATIENTS AND METHODS

We conducted a retrospective study of patients presenting with Lactobacillus bacteremia (LB), between January 2005 and December 2014, at the Grenoble University Hospital.

RESULTS

LB was observed in 38 patients (0.34% of all positive blood cultures). Cancer (40%), immunosuppression (37%), and use of central venous devices (29%) were frequently associated with LB. We observed a significant increase with time in the number of Lactobacillus positive blood cultures among all blood cultures performed (P=0.04). LBs were divided into two clinical-biological presentations: secondary bacteremia with a known portal of entry (n=30) and isolated bacteremia (n=8). Case fatality was 31% at D28, 55.2% at 1 year in the secondary bacteremia group, and 12.5% (both at D28 and 1 year) in the isolated bacteremia group. Secondary bacteremia with a known portal of entry was significantly associated with case fatality after adjustment for age, co-infection, cancer, immunosuppression, diabetes, and sex (OR 14.9 [1.04-216] P=0.047) for fatality at one year, but not for D28 fatality (P=0.14).

CONCLUSION

Lactobacillus bacteremia may be an important marker of disease severity rather than a pathogen, suggesting comorbidities. It should not be considered a contaminant, but should lead physicians to screen for associated infections and underlying diseases.

Évaluation de la prescription de l’agomélatine au sein de l’EPSM de l’agglomération Lilloise

Contexte

L’introduction de l’agomélatine est peu fréquente au sein de notre établissement, 39 patients sur les 925 patients sous antidépresseurs ont été répertoriés en un an, soit 4,21 %. L’objectif de cette étude était de comprendre pourquoi cet antidépresseur était si peu prescrit.

Méthodes

Une étude rétrospective a été réalisée sur 1 an (du 1/06/2014 au 1/06/2015) pour l’ensemble des services d’hospitalisation de l’établissement. Une analyse des prescriptions d’agomélatine a été effectuée à partir du logiciel Pharma® : posologie, durée, nombre de patients. La cause d’un éventuel arrêt ou d’un relais par une autre molécule a été évaluée à partir des informations recueillies dans les dossiers patients (logiciel Crossway®).

Résultats

Sur les 39 patients ayant reçu de l’agomélatine, la posologie était de 1 comprimé par jour pour 82 % des patients et 2 comprimés par jour pour les 18 % restant. Seize patients (41 %) ont arrêté le traitement sur cette période, la moyenne de durée de leur traitement était de 25 jours [1–90]. Concernant les causes d’arrêt du traitement, 6 patients (37,5 %) l’ont arrêté à cause d’effets secondaires somatiques (5 pour des troubles hépatiques, 1 pour trouble du sommeil type insomnie), 5 (31,25 %) pour cause d’inefficacité de la molécule dont 3 patients pour lesquels le traitement a été arrêté avant les 15 jours recommandés. Pour 3 patients la cause d’arrêt n’a pas été retrouvée. L’arrêt du traitement a été suivi par la prescription d’un autre antidépresseur sauf pour 2 patients où l’indication n’était plus retrouvée.

Conclusion

Le peu de prescription d’agomélatine peut s’expliquer par une efficacité jugée discutable de la molécule sur les pathologies dépressives nécessitant une hospitalisation mais aussi des effets secondaires hépatiques fréquents imposant une surveillance accrue. L’indication de l’agomélatine pour la pathologie dépressive traitée en hospitalisation est donc « discutée ».

Loudness modulation after transient and permanent hearing loss: implications for tinnitus and hyperacusis

Loudness is the primary perceptual correlate of sound intensity. The relationship between sound intensity and loudness is not fixed, and can be modified by short-term sound deprivation or stimulation. Deprivation increases sound sensitivity, whereas stimulation decreases it. We review the effects of short-term auditory deprivation and stimulation on the auditory central nervous system of humans and animals, and we extend the discussion to permanent auditory deprivation (hearing loss) and auditory pathologies of loudness perception. Although there is sufficient evidence to conclude that loudness can be modulated in normal hearing listeners by temporary sound deprivation and stimulation, evidence is scanter for the hearing-impaired listeners. In addition, cortical effects of sound deprivation and stimulation in humans, which may correlate with loudness coding, are still largely unknown and should be the target of future research.

Magnetic and micro-Raman studies of hexagonal-DyMnO3

Dc-susceptibility measurements and Raman active phonon frequencies of hexagonal DyMnO(3) retrace the Mn(3+) ions antiferromagnetic transition at T(N) ~ 70 K and their spin reorientation at T(SR) ~ 48 K. The temperature evolution of Raman active mode frequencies and their over-hardening are associated with Dy(3+) and Mn(3+) ion displacements below T(N) and with a spin-phonon coupling that involves apical oxygen.

[Using routine information system data to assess maternal and perinatal care services in Mali and Senegal (QUARITE trial)]

BACKGROUND

In sub-Saharan Africa, problems of access to relevant and high-quality facility-based statistics hinder the assessment of safe motherhood programs. The objective of this study was to assess the quality of data collected in referral hospitals in Mali and Senegal after the routine information system (RIS) was strengthened.

METHODS

This was a multicenter observational study conducted during the pre-intervention period of a randomized controlled trial (trial QUARITE). The RIS was strengthened based on technical, organizational and behavioral factors. We included all women who gave birth in the 46 referral hospitals from October 1, 2007 to October 30, 2008. The completeness, completion and accuracy rates were monitored every 3 months in each hospital. The cost of investment needed to strengthen the existing RIS was also determined.

RESULTS

The mean completeness rate ranged from 94 to 97% depending on the study period. The completion and accuracy rates increased during the study period from 72% and 79% to 87% and 93%, respectively (significant differences). The average investment per hospital was less than 1% of state subsidies for public hospitals.

CONCLUSION

Strengthening the existing information system has set up an economically and technologically appropriate system for monitoring maternal and perinatal health in Senegal and Mali. We encourage policy makers and researchers from countries with limited resources to invest in RIS to improve and monitor the performance of health systems.

[Obstetric care in Mali: effect of organization on in-hospital maternal mortality]

BACKGROUND

Maternal mortality is still too high in sub-Saharan Africa, particularly in referral hospitals. Solutions exist but their implementation is a great issue in the poor-resources settings. The objective of this study is to assess the effect of the organization of obstetric care services on maternal mortality in referral hospitals in Mali.

METHODS

This is a multicentric observational survey in 22 referral hospitals. Clinical data on 42,929 women delivering in the 22 hospitals within the 2007 to 2008 study period were collected. Organization evaluation was based on explicit criteria defined by an expert committee. The effect of the organization on in-hospital mortality adjusted on individual and institutional characteristics was estimated using multi-level logistic regression models.

RESULTS

The results show that an optimal organization of obstetric care services based on eight explicit criteria reduced in-hospital maternal mortality by 41% compared with women delivering in a referral hospital with sub-optimal organization defined as non-compliance with at least one of the eight criteria (ORa=0.59; 95% CI=0.34-0.92). Furthermore, local policies that improved financial access to emergency obstetric care had a significant impact on maternal outcome.

CONCLUSION

Criteria for optimal organization include the management of labor and childbirth by qualified personnel, an organization of human resources that allows timely management of obstetric emergencies, routine use of partography for all patients and availability of guidelines for the management of complications. These conditions could be easily implemented in the context of Mali to reduce in-hospital maternal mortality.
