ABSTRACT

OBJECTIVE:

To identify physicians' knowledge and attitudes regarding antimicrobial resistance and antibiotic prescribing practices at the University Hospital of the West Indies (UHWI).

METHODS:

A cross-sectional survey of physicians at the UHWI was conducted between September 2008 and April 2009 using a 28-item, self-administered questionnaire. Eligible physicians from several specialities were identified from departmental rotas.

RESULTS:

A total of 174 physicians completed the questionnaire, a response rate of 73%. Most physicians considered antibiotic resistance to be an extremely important global problem (55%) but less significant nationally (35%). Factors identified as important in producing resistance included wide-spread use of antibiotics (91%), inappropriate empiric choices (79%) and use of broad-spectrum agents (70%). Hand-washing was not considered to be important in reducing resistance. Useful interventions included access to current information on local resistance patterns (90%), institutional specific antibiotic guidelines (89%) and educational programmes (89%). Antibiotic cycling (40%) and restriction (35%) were regarded as less helpful. Knowledge of resistance-prone antibiotics and specific resistant organisms at the UHWI was poor, except for methicillin-resistant Staphylococcus aureus (MRSA). Empiric therapy for common infections was appropriate in most cases, and antibiotic choices were guided by availability of drugs (89%) and patient factors such as renal disease or allergy (80%). Only 45% of physicians would de-escalate to a narrow-spectrum antibiotic guided by a microbiology report, and consultants were more likely to de-escalate therapy than junior staff (p = 0.002).

CONCLUSIONS:

Although physicians were aware of the problem of resistance to antibiotics and the contributory factors, their practice did not reflect measures to reduce it. Continuing educational programmes and institution-specific antibiotic prescribing guidelines are needed.
RESUMEN

OBJETIVO:

Identificar los conocimientos y actitudes de los médicos con respecto a la resistencia antimicrobiana y la práctica de prescripción de antibióticos en el Hospital Universitario de West Indies (UHWI).

MÉTODOS:

Se llevó a cabo un estudio transversal en UHWI, entre septiembre del 2008 y abril del 2009 de abril, usando un cuestionario autoadministrado de 28 puntos. Los médicos elegibles de varias especialidades fueron identificados de las listas departamentales.

RESULTADOS:

Un total de 174 médicos completaron el cuestionario, para una tasa de respuesta del 73%. La mayor parte de los médicos consideró que la resistencia antibiótica constituye un problema sumamente importante desde un punto de vista global (55%) pero menos significativo desde una perspectiva nacional (35%). Los factores identificados como importantes en la formación de la resistencia incluyeron el uso generalizado de antibióticos (91%), las elecciones empíricas inapropiadas (79%), y el uso de agentes de amplio espectro (70%). El lavarse las manos no se consideró importante para la reducción de la resistencia. Las intervenciones útiles incluyeron el acceso a la información corriente sobre patrones de resistencia locales (90%), normas institucionales específicas sobre el uso de antibióticos (89%) y programas educativos (89%). El ciclo (40%) y la restricción (35%) de los antibióticos se consideraron menos útiles. El conocimiento de antibióticos con tendencia a la resistencia y organismos resistentes específicos en el HUWI era pobre, excepto en el caso del Staphylococcus aureus resistente a la meticilina (SARM). La terapia empírica para las infecciones comunes fue apropiada en la mayoría de los casos, y las opciones antibióticas estuvieron dictadas por la disponibilidad de medicamentos (89%) y factores relacionados con los pacientes, tales como enfermedades renales o alergias (80%). Sólo el 45% de los médicos desescalarían a un antibiótico de estrecho espectro guiado por un informe microbiológico, y los consultantes mostraron una tendencia mayor a desescalar la terapia, en comparación con la observada en el personal subalterno (p = 0.002).

CONCLUSIONES:

Aunque los médicos tenían conciencia del problema de la resistencia a los antibióticos y los factores contribuyentes, su práctica no reflejó las medidas para reducirla. Se necesitan programas de educación continua y normas institucionales específicas para la prescripción de antibióticos.
