Survey on physicians' knowledge and attitudes towards clinical practice guidelines at the Mexican Institute of Social Security.

OBJECTIVE: A survey was organized to determine the general level of knowledge and attitudes of medical personnel towards clinical practice guidelines (CPG). METHODS: A questionnaire modified from two validated instruments was used. Multi-stratified sampling was applied, and 1782 questionnaires were completed. RESULTS: A total of 80.4% of physicians had regular employment contract, 8.6% managerial post and 9.3% temporary work contract. Average age and working time were 43.7 and 15 years respectively; 64.3% were male. It was reported that 47.9% participated in academic activities, 70.8% belonged to a medical association, 40.3% identified CPG as steps towards arriving at a diagnosis and/or treatment and 14.9% thought that CPG were norms. A total of 10.7% of the physicians believed that guidelines are based on scientific evidence, 10% perceived them as supporting tools, 10.8% had no knowledge of them, 65% said that they used them, 76.7% thought that personal experience was as important as CPG recommendations and 57.4% thought that CPG were necessary for good medical practice. Physicians preferred that CPG be produced by personnel from outside the Mexican Institute of Social Security, or who had followed validity criteria. CONCLUSIONS: The majority of physicians considered CPG to be useful tools. It was evident that few knew where to acquire CPG, and this would lead to their limited use. Findings from this study enabled procuring a broader idea of the level of knowledge and attitudes of Mexican Institute of Social Security physicians towards CPG. This information is relevant when planning strategies for the purpose of sharing and implementing CPG.

[Nosocomial infection surveillance: experience at a cardiology hospital in Mexico]. / Vigilancia de infecciones nosocomiales: experiencia de un hospital de cardiología en México.

OBJECTIVE: To describe the results of the Nosocomial Infection surveillance program at the Cardiology Hospital in Centro Médico Nacional Siglo XXI of the Mexican Social Security Institute. METHODOLOGY: To inform of the epidemiologic follow-up results from January 2000 to July 2003. Global frequency, infection rates by infection site, hospital services, and frequency of most common microorganisms were estimated. RESULTS: During this period, global incidence showed that in every 100 discharges, there were 4.3 infections (4.3/100). Frequency of infection was slightly higher in the surgical intensive care unit. Average infection rate in lower respiratory tract infections was 27/1,000; in surgical-site infections: 8/1,000 (mediastinitis 0.8/1,000); it was found that in urinary tract infection, rate was 6.6/1,000. Most commonly isolated microorganisms were: coagulase-negative Staphylococcus (25%), Enterobacter sp. (17%), Candida albicans (13%), S. aureus (9%), P. aeruginosa (9%) and K. pneumoniae (6%). CONCLUSION: This study describes the epidemiology of nosocomial infections in a Cardiology Hospital. The information is obtained through epidemiologic follow-up programs. This information is very important to develop specific strategies for control of infections.
