Description

Technical Field

[0001] The present invention relates to the technical field of drug auditing, and in particular to a hospital internal auditing system and method based on drug management. Background Art

[0002] In the modern medical system, hospital drug management is a key link in ensuring medical quality and patient safety. With the widespread application of information technology in the medical field, hospital internal audits are gradually moving towards informatization and intelligence.

[0003] At present, in order to ensure the security of drug audit data, hospitals usually use keys to encrypt and store drug audit data. This method effectively prevents data from being illegally stolen and tampered with to a certain extent. However, as the "key" to open audit data, the security of the key is extremely important. If the key is lost, auditors will not be able to access and read the stored drug audit data normally. This will directly affect the development of audit work and make the generation of audit reports difficult. Because the accuracy and completeness of audit reports depend on the analysis and collation of comprehensive and accurate audit data, and the loss of keys will lead to the inability to obtain data, which will inevitably make the results of audit reports unreliable. In actual operations, hospital staff may lose keys due to various reasons, such as personnel changes, system failures, operational errors, etc. Once this happens, not only will it take a lot of time and effort to find or restore the key, but there may also be a risk that the data cannot be permanently restored, which will cause great trouble to the hospital's drug management and internal audit work.

[0004] In order to solve the above problems, the present invention proposes a solution. Summary of the invention

[0005] The purpose of the present invention is to provide a hospital internal audit system and method based on drug management, in order to solve the problems raised in the above background technology;

[0008] Each time drug summary data of a summary period is received, the ciphertext interaction unit generates ciphertext audit data of the corresponding summary period according to a preset generation rule, and transmits the ciphertext audit data to the drug audit module;

[0009] The drug audit module is used to periodically audit the stored drugs of the target hospital. The drug audit module pre-stores audit standard information, which includes several audit points, each of which corresponds to a preset audit score.

[0010] After receiving the transmitted ciphertext audit data of the current summary period, the drug audit module first stores it and sets the plaintext access permission;

[0011] The ciphertext audit data is then restored to obtain the corresponding ciphertext audit data, all stored drugs contained in the restored ciphertext audit data are automatically audited according to the audit standard information to obtain a corresponding audit report, the audit report is stored, and the restored ciphertext audit data is destroyed after the audit reports for all stored drugs are generated.

[0012] Furthermore, it also includes an information aggregation unit, which is used to periodically collect and aggregate the stored drug information of all stored drugs stored in the target hospital to obtain drug summary data of the corresponding aggregation period.

[0013] Furthermore, the rules for generating the ciphertext audit data for the current summary period are as follows:

[0014] S11: Create a 4*4 table, and fill the numbers 1-16 into the 16 cells in the table in order from top to bottom and from right to left according to 4 rows and 4 columns. Then, in the table, the 4 cells in the first row from left to right are filled with the numbers 13, 9, 5, and 1 in sequence, the 4 cells in the second row from left to right are filled with the numbers 14, 10, 6, and 2 in sequence, the 4 cells in the third row from left to right are filled with the numbers 15, 11, 7, and 3 in sequence, and the 4 cells in the fourth row from left to right are filled with the numbers 16, 12, 8, and 4 in sequence, wherein the above description of the number of rows in the table is the 1st, 2nd, 3rd, and 4th rows described in order from top to bottom;

[0015] S12: after the filling is completed, a ciphertext reference table is generated according to a preset interchange generation rule;

[0016] S13: performing binary conversion on the drug summary data of the current summary period, marking the binary data obtained after the conversion as the drug processing data of the current summary period, and obtaining the total number A1 of characters constituting the drug processing data;

[0017] S14: using formula B1=mod(A1,16) to calculate and obtain the starting selected amount B1 of the cell of the current summary period, and using formula C1=mod(A1,4) to calculate and obtain the dynamic extension amount C1 of the current summary period, wherein the dynamic extension amount is artificially defined to characterize the dynamic extension characteristics of the current summary period for the numbers filled in the table;

[0018] S15: Generate a ciphertext standard table of the current summary period according to the preset deferral rule and the dynamic deferral amount B1 of the current summary period;

[0019] S16: from left to right, every four characters in the drug processing data are taken as a group of processing strings to obtain a plurality of groups of processing strings, and according to the position of each group of processing strings in the drug processing data, the groups of processing strings are marked as G1, G2, ..., Gg from left to right, where g≥1;

[0020] S17: Obtain the ciphertext strings of the processing strings G1, G2, ..., Gg in sequence according to the preset acquisition rules;

[0021] S18: Concatenate the ciphertext strings in the order of processing strings G1, G2, ..., Gg to obtain the ciphertext audit data of the current summary period.

[0022] A hospital internal audit method based on drug management includes the following steps:

[0023] Step 1: The information summary unit periodically collects and summarizes the stored drug information of all stored drugs stored in the target hospital to obtain drug summary data of the corresponding summary period, and transmits the drug summary data to the ciphertext interaction unit;

[0024] Step 2: upon receiving drug summary data of a summary period, the ciphertext interaction unit generates ciphertext audit data of the corresponding summary period according to a preset generation rule, and transmits the ciphertext audit data to the drug audit module;

[0025] Step 3: After receiving the ciphertext audit data of each summary period, the drug audit module first stores it and sets the plaintext access permission;

[0026] The ciphertext audit data is then restored to obtain the corresponding ciphertext audit data, all stored drugs contained in the restored ciphertext audit data are automatically audited according to the audit standard information to obtain a corresponding audit report, the audit report is stored, and the restored ciphertext audit data is destroyed after the audit reports for all stored drugs are generated.

[0027] Beneficial effects of the present invention:

[0028] (1) The present invention sets an information summary unit to periodically collect and summarize and obtain the drug summary information of the target hospital, sets a ciphertext interaction unit to convert the drug summary data to obtain ciphertext audit data, wherein in the process of converting the ciphertext audit data, a conversion logic is used to replace key encryption, thereby avoiding the risk of key loss and leakage, and sets a drug audit module to store the ciphertext audit data in ciphertext and set plaintext access permissions, and temporarily restores the ciphertext audit data to automatically generate an audit report, and after the audit report is generated, the temporarily restored drug summary data is destroyed. In this way, the security of the ciphertext audit data before and after the audit is guaranteed, and the security of the audit results is further guaranteed;

[0029] (2) The present invention introduces a ciphertext reference table in the process of converting ciphertext audit data. A number of characters are filled in the ciphertext reference table. Each time drug summary information of a summary period is received, the identification starting cell and the iterative extension character of the corresponding summary period are determined according to the drug summary information. The digital characters updated in the ciphertext reference table in each summary period are determined by identifying the starting cell and the iterative extension character. In this way, the ciphertext audit data obtained in each summary period is made dynamic, which increases the complexity and security of the conversion process and makes unknown access and cracking more difficult.
