The purpose of this survey was to establish baseline information on blood component use in relation to patient diagnoses, procedures, and demographics and to identify patterns of blood use that may be used for blood program planning and transfusion audits.
A cross-sectional survey of the transfusion of blood components in teaching and nonteaching hospitals in central Ontario between September 1991 and August 1992 was carried out. Coders of hospital medical records routinely record demographics, procedures, diagnoses, and other relevant information. A protocol was created by which medical records coders could add the components transfused to the discharge abstract for this study. Red cell use is reported here.
Of the 61 hospitals invited to participate, from which 547,279 patients were discharged during the 12-month period of the study, 45 (74%) agreed to participate. Information was collected on 439,373 discharged patients. Of these, 26,611 (6.1%) received at least 1 unit of red cells. Of a total of 101,116 red cell units transfused, more than 74 percent were used in patients discharged with neoplasms, gastrointestinal diseases, circulatory system diseases, and trauma. High-transfusion-use procedures included operations and procedures on the digestive and cardiovascular systems, diagnostic and therapeutic procedures, musculoskeletal system, and hemic or lymphatic system procedures.
This survey provides baseline blood transfusion information for a specific period that can help determine the need for hospital audits and maximum surgical blood-order schedule guideline reviews. This information is relevant to current recommendations to reduce patient's exposure to blood components. These transfusion data will assist in blood program planning based on known disease trends, demographics, and population changes.
Rapid development, including the building of hydroelectric projects and roads in remote areas of Northern Quebec, Canada, has led to concerns about the contamination of traditional foods (TF) and a transition to a diet characterized by increased commercial food intake. A cross-sectional study of 850 Cree adults, aged =19 years, from 7 of the 9 Eeyouch communities was conducted during the spring and summer seasons of 2005-2008. Anthropometric measures were collected. TF and dietary intake were assessed using food-frequency questionnaires (FFQs) and 24-h recalls. Obesity was high, with 77% of the women and 64% of the men classified as obese. Past-year TF consumption was 100%, and 41% of participants reported eating TF on the 24-h recall. TF intake as reported on both the FFQs and the 24-h recalls was higher in individuals aged >50 years of age and in men, relative to younger adults and women, respectively. TF consumption increased protein, vitamin D, iron, and magnesium in all individuals, and energy, cholesterol, magnesium, sodium, and zinc in men aged 19-50 years; it decreased vitamin C in men and women aged =51 years. Participants reported drinking a mean daily 0.78 ± 1.34 cans of soft drinks or other high-sugar beverages per day or 5.28% ± 8.92% of total energy. It is important to identify behaviours that are contributing to obesity and its health consequences in this population and to find culturally appropriate ways to promote the consumption of TF and to reduce the consumption of energy-dense and nutrient-poor beverages and food items.
