Construction of evaluation index system of allocation and use of respiratory protection equipment in employers

  Objective  To develop a scientific evaluation index system to assess the allocation and use of employers' respiratory protection equipment.

  Methods  According to relevant national laws, regulations and standards, a preliminary index system through special group discussion was proposed, and then revised through two rounds of expert consultation and analysis. The weight of indicators at all levels was determined and the reliability and validity of the index system were calculated.

  Results  Four primary indicators and 25 secondary indicators of the initial indicator system framework were proposed based on the first round of consultation. Following experts' opinions and according to the inclusion criteria of the coefficient of variation and other indicators, 4 secondary indicators, namely the distribution of protective equipment, the wearing of protective equipment after cleaning, the penalties for violations of protective equipment, the use of well-known brand protective equipment, which did not meet the conditions were deleted. Through the second round of consultation and scoring, an evaluation index system including 4 first-level indicators, namely the allocation, the use, the maintenance and management, quality, and 21 second-level indicators was finally constructed. The effective response rate of 20 experts in two rounds of consultation was 100%, and the authority coefficient Cr was 0.896. The variation coefficients of the two rounds of expert consultation were 0.15 and 0.11 respectively, and the W values were 0.695 and 0.700 respectively(P < 0.05). The Cronbach's α of index system was 0.892 and the Spearman Brown half reliability coefficient was 0.860. The structural validity analysis of the index system was carried out, and the appropriateness test statistic (KMO value) was 0.736, indicating good validity.

  Conclusions  The two-level index evaluation system for the allocation and use of respiratory protective articles has been stable structurally and reasonably designed. It can be used as a practical evaluation tool for the rational use of respiratory protective articles in employers, and provide reference for administrative supervision and occupational health evaluation.
