Is it possible to identify a population in which the incidence of future development of AIS is greatly increased when compared to the normal population?

For future research of predictors of AIS, it would be advantageous to identify a general population in which the development of AIS is greatly increased when compared to the normal population. The probability of predicting future development of AIS among younger relatives of current patients based on the probability of AIS incidence was assessed from the research literature. Although there is considerable literature relating to familial relationships of the probability of developing AIS or having AIS, the probability is relatively low in most cases. Even with the best of predicted probabilities, the identification of patients with a high probability of developing AIS remained low. The identification of people among the general population who have a high probability of developing AIS based on the probabilities expressed in the literature is not possible.

Use of blood donation history of people with HIV infection to identify recipients at risk.

OBJECTIVE: To determine whether previous blood donations from HIV-positive patients posed a threat to recipients. DESIGN: Interviewer-administered questionnaire survey. SETTING: Regional HIV outpatient referral clinic for southern Alberta. PATIENTS: All 478 patients attending the clinic from May 1, 1993, to Mar. 31, 1994; 366 were excluded: 335 had not donated blood, and 31 could not provide reliable information regarding possible donations. INTERVENTIONS: Patients were asked at a routine clinic visit regarding the dates, frequency and location of previous blood donations. The Canadian Red Cross was informed, with patient consent, if the previous donations posed a potential risk of HIV transmission. OUTCOME MEASURES: Number of HIV-positive patients whose donations posed a possible or definite risk to recipients. RESULTS: A total of 545 units of blood had been donated by the 112 patients in the study; 57 units (donated by 29 patients) posed a possible risk, and 12 (given by 11 patients) posed a definite risk of HIV transmission to the recipients. Thirty-two of these donors had been unknown to the Red Cross through its "look-back" and "trace-back" protocols. Only 1 of the 13 patients found to be HIV positive by the Red Cross openly admitted donating blood to undergo HIV antibody testing; the remainder were either ill-informed or did not perceive themselves to be at risk. The patients were highly mobile, 36.7% donating blood at some time in a province other than the one where they had received their positive HIV test result. CONCLUSION: Asking HIV-positive patients about their blood donation history, although subject to recall bias, is a simple and inexpensive method for identifying high-risk blood donations. The Red Cross should routinely be notified, with patient consent, of all donations posing a risk in order to enhance the prospect for identifying HIV-positive blood recipients.
