Effect of a policy to reduce user fees on the rate of skilled birth attendance across socioeconomic strata in Burkina Faso
BACKGROUND: In Sub-Saharan Africa, maternal and neonatal morbidity and mortality rates are associated with underutilization of skilled birth attendance (SBA). In 2007, Burkina Faso introduced a subsidy scheme for SBA fees. The objective of this study was to evaluate the effect of Burkina Faso's subsidy policy on SBA rate across socioeconomic status (SES) strata. METHODS: We used a quasi-experimental design. The data sources were two representativ…
Estimating the Proportion of Cases of Lung Cancer Legally Attributable to Smoking
Objectives. The plaintiffs’ lawyers for a class action suit, which was launched in Quebec on behalf of all patients with lung cancer whose disease was caused by cigarette smoking, asked us to estimate what proportion of lung cancer cases in Quebec, if they hypothetically could be individually evaluated, would satisfy the criterion that it is “more likely than not” that smoking caused the disease. Methods. The novel methodology we developed is bas…
Risk factors for tobacco dependence in adolescent smokers
TD risk in adolescents is associated with intensity of recent cigarette consumption, while the role of more distant cigarette consumption appears small; subjects with slow nicotine metabolism and those with more depression symptoms are at increased risk of becoming tobacco dependent. The risk of being tobacco dependent is considerably higher in subjects who had previously developed the TD state
Comparing the Validity of Different Sources of Information on Emergency Department Visits
BACKGROUND: Emergency department (ED) use in Quebec may be measured from varied sources, eg, patient's self-reports, hospital medical charts, and provincial health insurance claims databases. Determining the relative validity of each source is complicated because none is a gold standard. OBJECTIVE: We sought to compare the validity of different measures of ED use without arbitrarily assuming one is perfect. SUBJECTS: Data were obtained from a nur…
