Estimation of increased hospital stay due to nosocomial infections in surgical patients: comparison of matched groups.

An investigation, using a prospective cohort study, was performed to estimate the prolongation of hospital stay caused by nosocomial infections in surgical patients. An evaluation of the one-to-one matching method, as a model for similar studies was also undertaken. Between 1992 and 1994, 225 of 1482 surgical patients (15%) developed infection. Of these, 223 evaluable patients were compared with 1256 uninfected cases, in an unmatched analysis. In a further analysis, 151 infected cases were matched one-to-one with uninfected controls, and other factors such as age, length of preoperative stay, presence of malignancy or diabetes and presence of foley catheters or drains, were evaluated. Patients with infection were hospitalized for 10.6 days longer than the matched controls. In the unmatched analysis, infected patients appear to remain in hospital for a further 17 days. The difference in the prolongation of stay between matched and unmatched groups indicates the importance of matching as an essential model for such studies. In cases where matching cannot be performed, the median can be a good alternative measure to the arithmetic mean.

Resistance against contraception or medical contraceptive methods: a qualitative study on women and men in Istanbul.

OBJECTIVES: This research was carried out to reveal the attitudes of men and women about contraception in the Umraniye district of Istanbul. METHODS: Focus group discussions were used for data collection. Data from 20 groups of married people (ten groups of men and ten of women) living in Umraniye were analyzed. RESULTS: Most people attending the focus groups in the study were against having 'too many' children. Economic constraints appear to be a leading influencing factor for limiting the number of children. Urbanization also seems to have a strong influence on people's knowledge and attitudes about contraception. Culture and religious beliefs were not found to be major barriers to contraception in general, but they would influence the selection of the type of a certain contraceptive method. More specifically, culture and religious beliefs were barriers to use of medical methods, and they were the main reasons for use of the withdrawal method, which is the most common method used in Turkey. CONCLUSIONS: Men and women are not resistant to contraception, but they are reluctant to use medical methods. The provision of contraceptive services, with special attention to cultural and religious beliefs and values, and the inclusion of appropriate counseling and education sessions during service delivery, may give clients new options and increase the use of medical methods.
