Procedure of safe handling with cytostatic drugs

Working group for safe handling with cytostatic drugs has been formed by the Ministry of Health, and it consists of professionals from IORS, Federal Bureau of Weights and Measures, Industrial Medicine, Institute of Hematology, Military Medical Academy, and Crown Agents. The aim of this working group is to prepare procedures for safe handling with cytostatic drugs, as well as program for educational seminar for nurses, medical technicians, and pharmaceutical technicians. The procedures will serve as a guide of good practice of oncology health care, and will refer to all actions that health care professionals carry out from the moment of drugs arrival to the pharmacy to the moment of their application. In the first segment of this procedure, general rules are given for working with cytotoxic agents, control for risky exposures, safe system of work, control of working environment, monitoring of the employees' health condition adequate protection in the working environment, protective equipment of the employees (gloves, mask, cap, eyeglasses, shoe covers, coats and chambers for vertical laminary air stream). Storing of cytostatics, procedure in case of accident, and waste handling and removal are also described in this segment. Fifty-three standard operational procedures are described in detail in the second segment. Training scheme for preparation of chemotherapy is given in the third segment - education related to various fields and practical part, which would be carried out through workshops, and at the end of the course participants would pass a test and obtain certificate. After the procedures for safe handling with cytostatics are legally regulated employer will have to provide minimum of protective equipment, special rooms for the drugs dissolving, chambers with laminar airflow, 6 hours working time, rotation of the staff working with drugs dissolving in intervals of every five years, higher efficiency, better health control. In conclusion this specific field of work requires great psychological and physical efforts, and know-how. When taking care of ourselves, we are taking care of the others, as well.

Post-exposure prophylaxis after non-occupational HIV exposure: impact of recommendations on physicians' experiences and attitudes.

To evaluate the impact of official recommendations for non-occupational HIV post-exposure prophylaxis (PEP), issued in France in 1998, on physicians' prescriptions and attitudes and the occurrence of severe PEP side-effects. Two surveys were carried out among hospital physicians involved in HIV care, before (1997) and after (1999) the publication of recommendations. Questionnaires explored, for the last 12 months, description of PEP requests and prescriptions, detailed description of the latest treated exposure, prescription attitudes towards five exposure scenarios and types of severe side-effects of antiretroviral drugs (in 1999 only). Nationally, from 1997 to 1999, PEP requests and prescriptions increased sevenfold and ninefold, respectively. Most requests followed sexual exposure (71% in 1997 and 86% in 1999; P = 10(-6)). The proportion of prescriptions for exposure to a known HIV-infected person decreased from 78% in 1997 to 41% in 1999 (P = 10(-6)). Three-drug combination therapies increased from 46% in 1997 to 83% in 1999 (P = 10(-6)). In 1999, 13 (0.9%; 95% confidence interval, 0.5-1.5%) severe reversible adverse events occurred among patients on a three-drug regimen. Prescription attitudes based mainly on risk assessment in 1997 (64% versus 33% in 1999) were based mainly on the request of the patient in 1999 (41% versus 11% in 1997). Recommendations were followed by an increase of PEP, particularly after less risky exposures, and a substantial risk of severe side-effects. PEP should be restricted to well-documented exposures for which the risk of transmission outweighs the risk of severe side-effects. Drug regimens should be revised.

HIV risks in the health care organization

Health-care workers who sustain an accidental parenteral exposure to HIV are at risk of infection. Although only incomplete data are available to assess the risk, these data are reassuring. The most important lesson for health-care workers in the AIDS era is that nearly all risky exposures can and should be prevented. Greater emphasis on needlestick safety, control of infection in high-risk environments and improved devices and procedures can alleviate the vast majority of hazardous exposures.
