Central sterile supply department (CSSD) management quality sensitive index constructed by management mode under the guidance of key point control theory and its effect on CSSD management quality: a retrospective study.

BACKGROUND: The central sterile supply department (CSSD) ensures the quality of medical care and controls infection. The professional, standardized, and scientific management of the CSSD is prerequisite if a hospital is to realize sustainable development. Based on the management mode and under the guidance of key point control theory, this study developed the CSSD management quality sensitive index to analyze its effects on the management quality of the CSSD. METHODS: We conducted a retrospective analysis of 282 medical devices processed from January 2020 to June 2020 (the control group), and 280 medical devices sterilized from July 2020 to December 2020 (the observation group). The devices in the control group were cleaned and disinfected according to the conventional operation process, while the observation group used a management quality sensitive index that had been developed according to the management mode, as guided by the key point control theory, and managed by the CSSD. The sensitive indexes of the two groups before and after the intervention were recorded to evaluate the work quality of CSSD medical staff. RESULTS: After the intervention, the process indexes, such as the qualified rate of cleaning quality, qualified rate of assembly, qualified rate of labeling, and correct rate of sterilization, the qualification rate of the sterilization results, the rate of intact packaging, and the rate of intact instruments, the environmental status, packaging quality, cleaning quality, and equipment management scores of the observation group were significantly higher than those of the control group (P<0.05). The incidence of wet packaging in the observation group was significantly lower than that in the control group (P<0.05). The service quality indexes, such as the replenishment time, retrieval time and preparation time of goods, of the observation group were significantly shorter than those of the control group (P<0.05). CONCLUSIONS: The quality sensitive index constructed under the guidance of the key point control theory can be used to guide the quality management of the CSSD, improve the processing results of key points in key control processes, and improve the work quality and service quality of the medical staff.

A synthesis and performance evaluation of a highly efficient ecological dust depressor based on the sodium lignosulfonate-acrylic acid graft copolymer.

In this paper, a highly efficient and environmentally-friendly dust depressor was developed based on the sodium lignosulfonate-acrylic acid graft copolymer. Using the grafting ratio as an index, a three-factor and four-level orthogonal experiment was conducted to optimize the fabrication conditions of the graft copolymer. At a reaction temperature of 60 °C, feed ratio m SLS-AA of 1 : 3, and FeSO4·7H2O content of 2.5%, the prototype produced the highest grafting ratio. The microstructure of the graft copolymer was measured using Fourier transform infrared spectrometry (FTIR) and nuclear magnetic resonance (1H-NMR). Furthermore, the influence of glycerol and the JFC penetrant on the contact angle between the compound solution and coal powder was investigated. Finally, four formulas of dust depressor were selected based on the experimental results. The dust-control performance of the four dust depressors was then tested on a large-scale spray dust suppression simulation platform. The results show that after applying formula 1 at various distances from the spray field, the average dust reduction rates of the total dust (respirable dust) at each point increased. Compared to the water-spraying dust suppression technique, the dust concentration is significantly reduced after the graft copolymer dust depressor is applied.
