Comparison of the reluctance of house staff of metropolitan and suburban hospitals to perform mouth-to-mouth resuscitation

Abstract

Background: Although performing mouth-to-mouth resuscitation (MMR) during cardiopulmonary resuscitation (CPR) is an effective lifesaving procedure, both the general public and physicians are often unwilling to perform CPR. Fear of contracting infectious diseases, especially AIDS, is often stated as the reason for this reluctance. However, the likelihood of saving a life usually outweighs the chance of contracting an infectious disease, especially when victims are considered to be at low risk for being HIV+ and are in communities with low incidences of HIV antibodies.

Methods: The entire housestaff (58 residents) in the Department of Internal Medicine of a suburban hospital responded to a questionnaire of hypothetical cardiac arrest scenarios in both inpatient and outpatient settings. Their responses were compared to those previously obtained from the housestaff (82 residents) of a hospital in a large metropolitan area with a high incidence of HIV positive patients.

Results: The willingness of the suburban housestaff (residents) to perform MMR in the inpatient scenario of a patient with an unknown risk for communicable infections was 43%, with trauma was 12%, with a perceived high risk for being HIV+ was 14%, and in the elderly was 29%, compared to 45, 16, 7 and 39%, respectively of the house staff of the metropolitan hospital. In outpatient scenarios, the willingness of the suburban housestaff to perform MMR on a victim with an unknown risk for communicable infections was 50%, with trauma was 33%, with a perceived high risk for being HIV+ was 34%, in the elderly was 26%, and in a child was 86%, compared to 54, 36, 21, 65, and 99%, respectively, of the metropolitan residents. Overall, the suburban male residents were more likely to be willing to perform MMR than the female ones, as were residents actively practising a religion or having graduated from medical schools in the United States. Suburban residents under 30 years of age seemed more willing to perform MMR in the majority of the scenarios than those over 30 years of age. Of the 31 suburban residents that stated they would be unwilling to perform MMR in at least one of the given scenarios, all stated that their unwillingness was due to fear of becoming infected with HIV or other infectious agents. In 1994, the percentage of known HIV positive individuals admitted to the suburban hospital was approximately five times less than that of the metropolitan hospital whose house staff was interviewed (P < 0.001).

Conclusions: Patients perceived to be at high risk for HIV were less likely to receive MMR than those at low risk. The reluctance of house staff to perform MMR in a suburban community hospital with a low incidence of HIV+ patients is similar to that of house staff in a large metropolitan community with a much higher incidence of infected patients. This reluctance, which was largely due to fear of contracting HIV infections, is not influenced by frequent contact with patients infected with HIV but is based on perceived rather than actual risks of contracting HIV. To increase the willingness of physicians, other medical personnel, and the lay public to perform MMR on victims of cardiac and respiratory arrests, the negligible risk of contracting infectious diseases while performing MMR should be emphasized. Use of portable barrier masks while performing MMR and an increase in their availability would decrease the minimal risks even further, and is recommended by the authors.
