Factors affecting interest in respiratory medicine as a subspecialty of choice: survey of internal medicine residents in Nigeria.

AIMS AND OBJECTIVES

The objective of this study was to determine the factors that affect the interest in respiratory medicine (RM) as a subspecialty of choice among internal medicine residents in Nigeria.

SUBJECTS, MATERIALS AND METHODS: This was a cross-sectional study of 136 internal medicine residents recruited from seven teaching hospitals from January 2011 to June 2011. A semi-structured questionnaire that was self administered by residents was used to obtain socio-demographic information and factors affecting residents' interest in respiratory medicine.

RESULTS

Out of 136 residents that completed the study, 78 (57.4 %) were junior residents (PG year 1-3) and 58(42.6%) were senior residents (PG year >3). Thirty four (43.6%) junior residents and 21(36.2%) senior residents considered respiratory medicine as a sub-specialty of choice. Only 2(3.5%) of the senior residents were presently committed to RM. In the junior residents, interest in respiratory medicine was correlated with personal intelligence and ability (RR=2.58, ;95% confidence interval(CI): 1.16-7.07, p-0.01) , availability of respiratory physician (RR=2.42; 95% CI 1.07-7.63 ,p-0.02) and postgraduate examiners in RM in training institutions RR= (2.20; 95% CI 1.06-5.45,p-0.03), experience during rotation in medical school and residency (RR=2.11 ; 95% CI 1.11-4.21,p-0.03) and future annual income (RR=2.04;C:I1.03-4.68,p-0.04). In the senior residents, interest in RM was correlated with the availability of postgraduate examiners in RM in training institutions (RR- 6.36; 95% CI 1.16-66.80, P-<0.01), future opportunity for scholarships and travel grants (RR- 4.23; 95% CI 1.19-25.92,p-< 0.01), personal intelligence and ability (RR= 3.41; 95% CI.16-13.87,p-0.01) and prospect for rapid elevation in career (RR=2.92; 95% CI 1.03-11.91,p -0.04). Provisions of modern facilities in training institutions, mentoring by senior colleagues and promotion of subspecialty by respiratory physicians were rated by the senior residents as the most important ways of increasing interest in respiratory medicine and making it a specialty of choice.

CONCLUSION

The interest in respiratory medicine among internal medicine residents is low and decline as their level of training advances. The factors affecting the interest in respiratory medicine have been highlighted and the policy makers need to understand, and if possible modify these factors by formulating appropriate changes to our training programs so as to increase future numbers of respiratory physician.
