Sortie précoce dans le post-partum : état des lieux en France

Determinants of Length of Stay After Vaginal Deliveries in the Friuli Venezia Giulia Region (North-Eastern Italy), 2005-2015

Although length of stay (LoS) after childbirth has been diminishing in several high-income countries in recent decades, the evidence on the impact of early discharge (ED) on healthy mothers and term newborns after vaginal deliveries (VD) is still inconclusive and little is known on the characteristics of those discharged early. We conducted a population-based study in Friuli Venezia Giulia (FVG) during 2005–2015, to investigate the mean LoS and the percentage of LoS longer than our proposed ED benchmarks following VD: 2 days after spontaneous vaginal deliveries (SVD) and 3 days post instrumental vaginal deliveries (IVD). We employed a multivariable logistic as well as a linear regression model, adjusting for a considerable number of factors pertaining to health-care setting and timeframe, maternal health factors, newborn clinical factors, obstetric history factors, socio-demographic background and present obstetric conditions. Results were expressed as odds ratios (OR) and regression coefficients (RC) with 95% confidence interval (95%CI). The adjusted mean LoS was calculated by level of pregnancy risk (high vs. low). Due to a very high number of multiple tests performed we employed the procedure proposed by Benjamini-Hochberg (BH) as a further selection criterion to calculate the BH p-value for the respective estimates. During 2005–2015, the average LoS in FVG was 2.9 and 3.3 days after SVD and IVD respectively, and the pooled regional proportion of LoS > ED was 64.4% for SVD and 32.0% for IVD. The variation of LoS across calendar years was marginal for both vaginal delivery modes (VDM). The adjusted mean LoS was higher in IVD than SVD, and although a decline of LoS > ED and mean LoS over time was observed for both VDM, there was little variation of the adjusted mean LoS by nationality of the woman and by level of pregnancy risk (high vs. low). By contrast, the adjusted figures for hospitals with shortest (centres A and G) and longest (centre B) mean LoS  were 2.3 and 3.4 days respectively, among “low risk” pregnancies. The corresponding figures for “high risk” pregnancies were 2.5 days for centre A/G and 3.6 days for centre B. Therefore, the shift from “low” to “high” risk pregnancies in all three latter centres (A, B and G) increased the mean adjusted LoS just by 0.2 days. By contrast, the discrepancy between maternity centres with highest and lowest adjusted mean LoS post SVD (hospital B vs. A/G) was 1.1 days both among “low risk” (1.1 = 3.4–2.3 days) and “high risk” (1.1 = 3.6–2.5) pregnanices. Similar patterns were obseved also for IVD. Our adjusted regression models confirmed that maternity centres were the main explanatory factor for LoS after childbirth in both VDM. Therefore, health and clinical factors were less influential than practice patterns in determining LoS after VD. Hospitalization and discharge policies following childbirth in FVG should follow standardized guidelines, to be enforced at hospital level. Any prolonged LoS post VD (LoS > ED) should be reviewed and audited if need be. Primary care services within the catchment areas of the maternity centres of FVG should be improved to implement the follow up of puerperae undergoing ED after VD.

Length of stay following cesarean sections: A population based study in the Friuli Venezia Giulia region (North-Eastern Italy), 2005-2015

BACKGROUND

Births by cesarean section (CS) usually require longer recovery time, and as a result women remain hospitalized longer following CS than vaginal delivery (VD). A number of strategies have been proposed to reduce avoidable health care costs associated with childbirth. Among these, the containment of length of hospital stay (LoS) has been identified as an important quality indicator of obstetric care and performance efficiency of maternity centres. Since improvement of obstetric care at hospital level needs quantitative evidence, we compared the maternity services of an Italian region on LoS post CS.

METHODS

We conducted a population-based study in Friuli Venezia Giulia (FVG), a region of North-Eastern Italy, collecting data from all its 12 maternity centres (coded from A to K) during 2005-2015. We fitted a multivariable logistic regression using LoS as a binary outcome, higher/lower than the international early discharge (ED) cutoffs for CS (4 days), controlling for hospitals as well as several factors related to the clinical conditions of the mothers and the newborn, the obstetric history and socio-demographic background. Results were expressed as adjusted odds ratios (aOR) with 95% confidence interval (95%CI). Population attributable risks (PARs) were also calculated as proportional variation of LoS>ED for each hospital in the ideal scenario of having the same performance as centre J (the reference) during calendar year 2015. Results were expressed as PAR with 95%CI. Differences in mean LoS were also investigated with a multivariable linear regression model including the same explanatory factors of the above multiple logistic regression. Results were expressed as adjusted regression coefficients (aRC) with 95%CI.

RESULTS

Although decreasing over the years (5.0 ± 1.7 days in 2005 vs. 4.4 ± 1.7 days in 2015), the pooled mean LoS in the whole FVG during these 11 years was still 4.7 ± 1.7 days, higher than respective international ED benchmark. The significant decreasing trend of LoS>ED over time in FVG (aOR = 0.89; 95%CI: 0.88; 0.90) was marginal as compared to the variability of LoS>ED observed among the various maternity services. Regardless it was expressed as aRC or aOR, LoS after CS was lowest in hospital C, highest in hospital D and intermediate in centres I, K, G, F, A, H, E, B and J (in descending order). The aOR of LoS being longer than ED ranged from 1.63 (95%CI:1.46; 1.81) in hospital B up to 32.09 (95%CI: 25.68; 40.10) in facility D. When hospitals were ranked by PAR the same pattern was found, even if restricting the analysis to low risk pregnancies.

CONCLUSIONS

Although significantly decreasing over time, the mean LoS in FVG during 2005-2015 was 4.7 days, higher than the international threshold recommended for CS. There was substantial variability in LoS by facility centre, suggesting that internal organizational processes of single hospitals should be improved by enforcing standardized guidelines and using audits, economic incentives and penalties if need be.

The impact of a patient's social status on the cost of vaginal deliveries: an observational study in a French university hospital

INTRODUCTION

We aimed to assess the association between a patient's social status and the cost of stay for a single uncomplicated vaginal delivery. Currently, few data have been reported.

MATERIAL AND METHODS

We conducted an observational study with data retrieved from the medical and administrative databases of a university hospital in North-West France. We included all patients admitted in 2014 and classified in either Diagnosis-Related Group (DRG) « Single uncomplicated vaginal deliveries in a primiparous patient » or DRG « Single uncomplicated vaginal deliveries in a multiparous patient ». Criteria defining poor social status were: a specific healthcare benefit in relation to low income or for foreign undocumented patients, and/or a consultation with a social worker during the hospital stay except if no social problem was diagnosed. We compared the cost of stay between patients with poor social status and patients with good social status using a multivariate median regression stratified on parity, and adjusted for age, gestational age and neonatal hospitalization.

RESULTS

Among 686 primiparous patients, 21% had poor social status, which was associated with an increase in the median cost of stay (+€475; 95% CI [+334 to +616]), mostly explained by a 1-day increase in the median length of stay.Among 899 multiparous patients, 29% had poor social status, which was not associated with the cost of stay.

DISCUSSION

Social status had an impact on the cost of vaginal deliveries in primiparous patients. Our findings suggest a need to redefine the DRG classification according to patients' social status.

Early postpartum discharge and breastfeeding: an observational study from France

BACKGROUND

Early postpartum discharge is a recent practice in France, but the influence of a shortened hospital stay on subsequent breastfeeding is unknown. The objective of the present study was to compare the breastfeeding mode after early discharge (ED) and conventional discharge (CD) from a hospital maternity unit.

METHODS

An observational study was conducted in a French university hospital among 135 breastfeeding mothers, who delivered between 1 January and 31 July 2006. Forty-five ED mothers were matched with 90 CD mothers on 13 criteria. A structured questionnaire was used to collect data regarding feeding practices at 10 weeks postpartum, the period corresponding to paid maternity leave.

RESULTS

Exclusive breast-, mixed, and bottle feedings were reported by, respectively, 35 (77.8%), three (6.7%) and seven (15.5%) ED mothers and 64 (71.1%), 12 (13.3%) and 14 (15.6%) CD mothers (no significant differences). Satisfaction with support for breastfeeding and reasons for switching to mixed or bottle feeding were comparable in the two groups. Multivariate analysis indicated that only the planned duration of breastfeeding and the mother's dissatisfaction with help significantly influenced breastfeeding prevalence.

CONCLUSIONS

Early postpartum hospital discharge organized by skilled professionals is compatible with a satisfactory rate of exclusive breastfeeding up to the return to work. Formalized programs of instruction for perinatal professionals would help to reduce early abandonment.

Is a breech presentation at term more frequent in women with a history of cesarean delivery?

OBJECTIVE

The purpose of this study was to determine whether breech presentation at term is more common among women with at least 1 previous cesarean delivery.

STUDY DESIGN

This historic cohort study (n = 84,688) included women with a singleton term pregnancy and at least 1 previous delivery. Results were expressed as crude relative risks and adjusted odds ratios.

RESULTS

While 2.46% of women had a fetus in breech presentation at term, 14.91% of women had had 1 or more previous cesareans. The relative risk of a breech presentation at term for women with a history of cesarean was 2.18 (95%CI: 1.98-2.39). It did not differ according to the number of previous cesareans. The logistic regression analysis took into account confounding factors including gestational age, maternal age, parity, birthweight, and oligohydramnios. The adjusted odds ratio was 2.12 (95%CI: 1.91-2.36).

CONCLUSION

Women with previous cesarean deliveries have a risk of breech presentation at term twice that of women with previous vaginal deliveries.
