Using a self-designed questionnaire on knowledge of pulmonary tuberculosis with diabetes, a random sampling method was used to randomly select two tertiary 3A hospitals from the five tertiary 3A hospitals in Hunan province which had TB departments (Hunan Chest Hospital and Changsha Central Hospital). Afterwards, based on the inclusion criteria, 280 eligible nurses from the TB departments were surveyed by cluster sampling. A total of 280 questionnaires were sent out and 269 valid questionnaires were collected, with an effective response rate of 96.07% (269/280). The results of the questionnaires were analyzed with SPSS 20.0. F test was used to analyze the data with normal distribution, and multiple group comparison was done with LSD test. The non-normal data were analyzed with Welch test and Tamhane’s T ² test, P<0.05 indicated the difference was statistically significant.

The average score of knowledge of pulmonary tuberculosis complicated by diabetes mellitus among the nurses inform tuberculosis department was (26.13±6.15), and the correct rate was 65.32% (26.13/40). The average scores of the different groups with different professional titles were as followed:(22.33±3.97) among the nurses group;(24.47±4.49) among the senior nurses group; (32.08±4.90) among the nurse-in-charge group; and (35.05±3.93) among the group with deputy directors or above. The difference between the groups was statistically significant (F=87.947,P<0.05). The average scores of the different groups with different highest educational attainment were as followed:(20.90±5.51) among those with technical secondary school degree;(23.17±4.01) among the group with associate-degree; (31.64±3.97) among the group with bachelor’s degree;(37.20±2.28) among the group with master’s degree or above. The difference between the groups was statistically significant (F=106.016,P<0.05). The average scores of the different groups with different contracts were as followed:(24.73±6.04) among the group with temporary contracts;(27.05±6.21) among the group with nurses on the payroll of manning quotas, and (27.45±5.70) among the group with long term contracts. The dif-ference between the groups was statistically significant (F=5.410,P<0.05). The average scores of the different groups with different years or nursing experience were as followed:(22.79±4.87) among the group with 0-5 years of nursing experience;(28.89±5.17) among the group with 5-10 years of nursing experience; (31.22±4.45) among the group with 10-20 years of nursing experience; and (34.00±4.69) among the group with 20 or more years nursing experience.

Department of tuberculosis nurses’ knowledge on pulmonary tuberculosis complicated by diabetes needs to be improved; the professional titles, the highest degree attainment, the contract types and work experience are the main factors affecting the knowledge of pulmonary tuberculosis complicated by diabetes mellitus.
