Validity of the cross-sectional study for the ascertainment of nosocomial infection risk factors.
This study was carried out in order to assess the validity of the pure cross-sectional study in the ascertainment of nosocomial infection risk-factors.
The results yielded by two designs (crosssectional and case-control) are compared.
A cross-sectional design was performed in a tertiary hospital. 592 patients were studied, 38 of whom were nosocomially infected.
The clinical information on all the patients included in this design was reviewed after hospital discharge.
A matched case-control study was nested in the population cross-sectionally surveyed. 66 cases (28 additional patients developed a hospital infection) and 132 controls were selected.
Odds ratios (ORs) for the risk factors analyzed by both designs were compared.
