[Analysis of comorbidities in hospitalized patients for ischemic stroke and their effects on lethality]

OBJECTIVES

The aim of the study consists of analyzing the comorbidities of acute ischemic stroke and those influencing its hospital lethality.

METHODS

We considered patients from Wallonia aged 25 years or more and admitted to a Belgian hospital for an acute ischemic stroke in 2013 and 2014. The analyzed medico-administrative data are taken from the Minimum Hospital Summary. A factorial correspondence analysis (FCA) was used to demonstrate the comorbidities profiles. A logistic regression was used to analyse the comorbidities influencing hospital lethality by ischemic stroke.

RESULTS

The stroke risk factors vary according to the age. Cardiac problems are more common in older people aged 85 years or more. High blood pressure, hypercholesterolemia and diabetes are more present between 65- and 84-year-olds. Overweight is more present between 55 and 74-year-olds. People who are addicted to alcohol or tobacco are often 65 years or younger. The logistic regression showed that age and heart problems are the risk factors that increase lethality. However there is a lethality diminution in the presence of high blood pressure, hypercholesterolemia, overweight and addiction to alcohol or tobacco.

CONCLUSION

This study demonstrates that medico-administrative databases and factorial statistical methods are perfectly adapted to confirm the ischemic stroke risk factors. This type of study will allow to target with more precision the secondary and tertiary prevention actions of stroke.

Reducing financial barriers to emergency obstetric care: experience of cost-sharing mechanism in a district hospital in Burkina Faso

OBJECTIVE

To describe the implementation of a cost-sharing system for emergency obstetric care in an urban health district of Ouagadougou, Burkina Faso and analyse its results after 1 year of activity.

METHODS

Service availability and use, service quality, knowledge of the cost-sharing system in the community and financial viability of the system were measured before and after the system was implemented. Different sources of data were used: community survey, anthropological study, routine data from hospital files and registers and specific data collected on major obstetric interventions (MOI) in all the hospitals utilized by the district population. Direct costs of MOI were collected for each patient through an individual form and monitored during the year 2005. Rates of MOI for absolute maternal indications (AMI) were calculated for the period 2003-2005.

RESULTS

The direct cost of a MOI was on average 136US$, including referral cost. Through the cost-sharing system this amount was shared between families (46US$), health centres (15US$), Ministry of Health (38US$) and local authority (37US$). The scheme was started in January 2005. The rate of cost recovery was 91.3% and the balance at the end of 2005 was slightly positive (4.7% of the total contribution). The number of emergency referrals by health centres increased from 84 in 2004 to 683 in 2005. MOI per 100 expected births increased from 1.95% in 2003 to 3.56% in 2005 and MOI for AMI increased from 0.75% to 1.42%.

CONCLUSIONS

The dramatic increase in MOI suggests that the cost-sharing scheme decreased financial and geographical barriers to emergency obstetric care. Other positive effects on quality of care were documented but the sustainability of such a system remains uncertain in the dynamic context of Burkina Faso (decentralization).
