Construction and Validation of an Individual Deprivation Index: a Study Based on a Representative Cohort of the Paris Metropolitan Area

The association between health status and deprivation is well established. However, it is difficult to measure deprivation at an individual level and already-existing indices in France are not validated or do not meet the needs of health practitioners. The aim of this work was to establish a validated, easy-to-use, multidimensional, relevant index that was representative of the population in the Paris metropolitan area. From the SIRS 2010 cohort study, 14 socio-economic characteristics were selected: health insurance, educational background, socio-professional category, professional status, feelings of loneliness, emotional situation, household type, income, perceived financial situation, social support (support in daily life, financial and emotional), housing situation, and migration origin. In addition, a total of 12 health status, healthcare use, and nutrition-related variables were also selected. Content validity and internal validity of the index were explored. The 14 socio-economic indicators were associated to varying degrees with poorer health status, less use of healthcare, and poorer nutrition and were distributed across the 14 multiple-choice questions of the index. Each answer was rated from 0 to 2. The index value of 10 that isolates 20% of the most deprived individuals was used as threshold. "Being deprived," as defined with this value, was significantly associated with 9 of the 12 studied health variables. This index could be a relevant instrument in the assessment of deprivation and social inequalities of health.

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.

OBJECTIVES

This paper considers the specific administrative procedures set up by managers of public healthcare establishments and those responsible for health and welfare policies to care for low-income pregnant women for whom 100% of the "price per act" (T2A) is refunded. What are the limitations and what improvements can be suggested?

PATIENTS AND METHOD

The results are based on an analysis of data from semi-structured interviews, legislation and documents.

RESULTS

The State, health insurance systems, public health establishments, local authorities, charities and outpatient services are involved in handling low-income parturients in different services and different establishments, both locally and regionally. A health and welfare policy comprising specific, coordinated actions and measures has been developed. The T2A "price per act" system may threaten its survival: the limited number of front-line facilities is often saturated and demand is increasing, treatment is often reduced to reactive management leading to unwanted readmissions, ethics are sometimes called into question and there is a risk of patient selection.

DISCUSSION AND CONCLUSION

This pilot study provided some encouraging information but also indicated the limitations of the approach adopted. However, it was still of interest to see whether it was possible to use this approach, which did not require considerable resources, to reveal useful markers. This appeared to be the case. Regional Health Agencies (ARS) and local authorities could support the system. Additional funding is needed.
