Application of control charts in hospital data quality management / 中华医院管理杂志

Objective:To study the feasibility of control charts in the quality management of hospital statistical data as a reference for improving such management.Methods:Main business indicators of the main campus and some business indicators of the affiliated campus of a tertiary general hospital from January to May 2022 were selected. K-S test and chi-square goodness of fit test were used to test data in its statistical daily report, analyzing whether the data conform to the specific distributions. Then appropriat control chart were used according to the data type and distribution type. Minitab 21.1 software was used to draw the hospital data quality control chart, and data quality was monitored by analyzing the distribution of data points in the control chart.Results:The test found that the number of admissions, ultrasound examinations and emergency department visits in the main campus, and CT examinations in the affiliated campus, conformed to normal distribution, and single value control charts were applied. The number of ambulance trips in the main campus and the affiliated campus conform to Poisson distribution, and the defect number control chart was applied. The number of inpatient deaths in the main campus conform to a geometric distribution, and a rare event control chart was applied. The volume of admissions and ultrasound examinations in the main campus were mostly influenced by other factors, and the single-value selective control chart was used to further determine the cause of abnormal data distribution. The results of the control chart analysis showed that, there were no abnormal points in the data distribution of admissions, color ultrasound volume and in-hospital deaths in the main campus, two abnormal points in the CT examination volume in the affiliated campus. The control charts for the number of emergency department visits in the main campus and the number of ambulance trips in the main and affiliated campuses each had one outlier. It was verified that one anomaly in the volume of CT examinations in the affiliated campus and one anomaly in the number of ambulance trips in the affiliated campus were caused by data errors, while the other data were correct.Conclusions:It is feasible to use control charts to monitor the quality of hospital data, which can be used as a quality management tool to assist the quality management of hospital data.

Fingerprint establishment ，chemical pattern recognition analysis and content determination of Kangfuyan capsules / 中国药房

OBJECTIVE To establish the fingerprints of Kangfuyan capsules and carry out chemical pattern recognition analysis，and simultaneously determine the contents of five components so as to promote the quality standard of the drug. METHODS High performance liquid chromatography （HPLC）fingerprints of 11 batches of Kangfuyan capsules （S1-S11）were established by Similarity Evaluation System of TCM Chromatographic Fingerprint （2012 edition）；identification and attribution analysis of chromatographic peaks were carried out by comparison with the chromatograms of the reference substance and the decoction pieces of single ingredient. SPSS 26.0 and SIMCA 14.1 software were used for cluster analysis and principal component analysis. HPLC method was used to determine the contents of matrine ，phellodendrine chloride ，rutin，forsythoside A and berberine hydrochloride. RESULTS There were 29 common peaks in the fingerprints for 11 batches of samples ，and the similarity was higher than 0.99. A total of 5 chromatographic peaks were identified ，which are matrine （peak 3），phellodendron chloride （peak 14），rutin （peak 20），forsythiaside A （peak 22） and berberine hydrochloride （peak 28）. The results of cluster analysis and principal component analysis showed that S 1-S9 were clustered into one category ，and S 10 and S 11 were clustered into another category. The contents of above 5 components were 29.320 5-60.144 3，0.621 6-1.076 6，1.025 9-2.830 5，2.899 3-6.212 7 and 4.425 1-8.581 6 mg/g， respectively. CONCLUSIONS The established fingerprint and content determination method are stable and reliable ，and can provide reference for the quality control of the preparation in combination with chemical pattern recognition analysis.

The design and application of HIS-based inpatient expense check system / 中国医学装备

Objective: To prevent the error of overcharging fees, missing fees and mistaken identity fees, check the inpatient expense rationality with using the self-developed software system. Methods:With extracting data from HIS and other systems, check and audit the inpatient expense, such as billing classification, red account records, logic checks, integrity checks, etc, according to pre-established rules. Results:Using the auditing software can greatly improve the work efficiency and the accuracy of inpatient expense, reduce the incidence of billing dispute issue. Conclusion:This system has valuable reference and be worth generalizing because it can bring the social benefit to hospital.
