It is a method of centralized management or outsourcing management of the logistics processes of medical supplies supply, processing, and distribution in hospitals, led by the hospital's medical supplies management department and using logistics information technology as a tool, through the rational use of social resources.

[0003] In the existing medical system, there are often many problems in the management of medical supplies and consumables, such as chaotic inventory management, replenishment of medical supplies and consumables only through regular ordinary procurement, untimely supply of materials and inability to intelligently analyze procurement types, and inability to make judgments and inferences based on the recent usage of medical supplies and consumables, resulting in emergency procurement only when certain medical supplies and consumables are needed, wasting time. Medical supplies and consumables that do not need to be purchased urgently are easily accumulated, causing serious waste, which not only affects the hospital's operating efficiency, but may also have an adverse effect on the patient's treatment.

[0004] To this end, the present invention provides a medical SPD material consumables logistics management method. Summary of the invention

Set a collection cycle to obtain the total usage of this type of medical supplies and consumables within the collection cycle, and then obtain the ratio of the total usage of the medical supplies and consumables to the total collection time to obtain the usage frequency value of this type of medical supplies and consumables. The usage frequency value is multiplied by the distribution cycle to obtain the distribution period usage value.

[0020] Preferably, the reserve difference value is compared with the reserve difference threshold value, specifically:

[0021] The reserve difference threshold includes a first threshold and a second threshold, and the first threshold is smaller than the second threshold;

BRIEF DESCRIPTION OF THE DRAWINGS

[0045] The present invention will be further described below in conjunction with the accompanying drawings.

[0046] Figure 1 It is a method flow chart of a medical SPD material consumables logistics management method of the present invention. DETAILED DESCRIPTION

[0047] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0048] Embodiment 1

[0049] like Figure 1 As shown, a medical SPD material consumables logistics management method according to an embodiment of the present invention includes:

[0050] Step 1, obtaining usage data of various medical supplies and consumables in the medical database; analyzing and obtaining usage frequency values ​​of various medical supplies and consumables according to the usage data of various medical supplies and consumables, and calculating the product of the usage frequency value and the delivery period to obtain the delivery period usage value;

[0051] In some embodiments, the medical database is a cloud platform for recording medical supplies and consumables in the hospital, which is used to record the in-and-out quantity of medical supplies and consumables and store data; the daily usage of various types of medical supplies and consumables is obtained through the medical database and marked as the usage data of medical supplies and consumables;

[0052] The usage frequency values ​​of various medical supplies and consumables are analyzed and the usage frequency values ​​are multiplied by the delivery cycle to obtain the usage value during the delivery period, which is:

[0053] The distribution cycle is the time required for the purchase of drugs to their warehousing, which is generally 7 or 14 days. It can be set according to actual conditions. The collection cycle is set, and the collection cycle is divided into several collection moments. The total usage of this type of medical supplies and consumables within the collection cycle is obtained, and then the ratio of the total usage of the medical supplies and consumables to the total collection moments is obtained to obtain the usage frequency value of this type of medical supplies and consumables. The usage frequency value is multiplied by the distribution cycle to obtain the distribution period usage value.

[0054] It should be noted that the usage frequency value of medical supplies and consumables is obtained by ratioing the total usage of medical drugs within the collection period to the total collection time. The collection time can be carried out on a daily basis, and the average daily usage, i.e., the usage frequency value, is calculated. By calculating the product of the usage frequency value and the delivery period, the total usage of this type of medical drugs within the delivery period can be obtained, thereby obtaining the usage value of the delivery period.

[0055] Step 2, obtaining the storage values ​​of various types of medical supplies and consumables in the hospital from the medical database, performing difference calculation between the storage amount of various types of medical supplies and consumables and their corresponding distribution period usage values, obtaining the storage difference of various types of medical supplies and consumables, and comparing the storage difference with the storage difference threshold; wherein the storage difference threshold (the storage difference threshold is obtained based on the historical data of the hospital) includes a first threshold and a second threshold, and the first threshold is less than the second threshold;

[0056] If the reserve difference is less than the first threshold, it indicates that the stock of such medical supplies is insufficient, and an emergency purchase signal is generated;

[0057] If the first threshold ≤ the reserve difference ≤ the second threshold, it is not possible to determine whether the inventory of such medical supplies is sufficient, and a signal to be analyzed is generated;

[0058] If the reserve difference is greater than the second threshold, it indicates that the inventory of such medical supplies is sufficient, and a general procurement signal is generated;

[0059] It should be noted that the reserve difference is calculated by taking the difference between the storage volume of medical supplies and the usage value of the corresponding delivery period, which can indicate whether the storage volume can meet the basic requirements of use before the next purchase of materials is put into storage, and there will be no shortage of materials; when the reserve difference is less than the first threshold, it indicates that the inventory of such medical supplies is insufficient, and an emergency procurement signal is generated. The emergency procurement signal indicates that such medical supplies cannot be used until the next ordinary procurement cycle, and immediate procurement is required to ensure that such medical supplies will not be lacking; when the first threshold is ≤ If the reserve difference is ≤ the second threshold, it is impossible to determine whether the inventory of this type of medical supplies and consumables is sufficient, and a signal to be analyzed is generated. If the reserve difference is greater than the second threshold, it indicates that the inventory of this type of medical supplies and consumables is sufficient and no emergency purchase is required, and a normal purchase signal is generated. The normal purchase signal means that the hospital purchases medical supplies and consumables based on large-scale procurement needs. The time interval will be longer and the procurement volume will be larger. By comparing the quantity difference with the reserve difference threshold, it is possible to intelligently determine whether medical supplies and consumables need to be urgently purchased, avoid shortages of medical supplies and consumables, and improve the level of material management.

[0060] Step 3, based on the signal to be analyzed, obtain the usage of this type of medical supplies and consumables at each collection moment in the collection period, sum and average them, obtain the usage mean, calculate the difference between the usage of this type of medical supplies and consumables at each collection moment and the usage mean, and obtain the usage deviation value;

[0061] Compare the usage deviation value at each collection moment with the usage deviation value threshold (the usage deviation value threshold is obtained based on historical experience);

[0062] If the usage deviation value is less than or equal to the usage deviation value threshold, it means that the usage at the collection time has a small deviation from the usage mean, and the usage deviation value at the collection time is marked as a stable deviation value;

[0063] If the usage deviation value is greater than the usage deviation value threshold, it means that the usage at the collection time has a large deviation from the usage mean, and the usage deviation value at the collection time is marked as a fluctuation deviation value;

[0064] All stable deviation values ​​within the acquisition period are summed and averaged to obtain the stable deviation value mean;

[0065] All fluctuation deviation values ​​within the collection period are summed and averaged to obtain the fluctuation deviation mean value;

[0066] The ratio of the mean value of the stable deviation value to the mean value of the fluctuating deviation value is calculated to obtain the acquisition period usage characterization value BZ;

[0067] It can be understood that, based on the signal to be analyzed, by analyzing the usage of medical supplies and consumables within the collection period and performing difference calculation with the usage mean within the collection period, the usage deviation value at each collection moment can be obtained, and compared with the usage deviation value threshold, the stability of the usage of medical supplies and consumables within the collection period is judged, and the collection period usage characterization value is obtained by calculating the ratio of the mean of the stable deviation value to the mean of the fluctuation deviation value. The larger the collection period usage characterization value, the more stable the usage of such medical supplies and consumables, and there has been no large data fluctuation in the recent period. When predicting and calculating the usage value in the subsequent delivery period, the result is more accurate. Conversely, when the collection period usage characterization value is smaller, it means that the usage of medical supplies and consumables fluctuates greatly, and the result is less accurate when predicting and calculating the usage value in the subsequent delivery period.

[0068] Step 4: compare the usage characterization value of the collection period with the usage characterization value threshold (the usage characterization value threshold is set by the staff in this field based on historical data summary) to generate a stable usage signal or an unstable usage signal;

[0069] In a specific embodiment, the acquisition period usage characterization value is obtained, and the acquisition period usage characterization value is compared with the usage characterization value threshold:

[0070] If the acquisition period usage characterization value is greater than or equal to the usage characterization value threshold, a stable usage signal is generated;

[0071] If the acquisition period usage characterization value is less than the usage characterization value threshold, an unstable usage signal is generated;

[0072] In this embodiment, after obtaining the usage characterization value of the collection period, it is compared with the usage characterization value threshold, and a stable usage signal or an unstable usage signal can be generated; by analyzing the stability of the usage of this type of medical supplies and consumables at each collection moment in the collection period, it can be determined whether there are fluctuations in medical supplies and consumables in the near future, because when some influenza viruses appear, there will be a short-term rapid consumption of a certain drug. By monitoring and analyzing the collection period, a better judgment can be made on the stability of recent data, which is convenient for the subsequent management of medical supplies and consumables.

[0073] Step 5: Based on the stable usage signal, the signal to be analyzed is converted into a common procurement signal output.

[0074] Embodiment 2

[0075] Based on the unstable usage signal, the individual logistics time of this type of medical supplies from the production site to the current hospital location is obtained, and the individual logistics time representation value DS is obtained by combining the distribution cycle analysis;

[0076] Obtain the separate logistics freight costs and general procurement and transportation costs of this type of medical supplies and consumables, and analyze to obtain the separate logistics cost representation value FY;

[0077] Substitute the collection cycle usage characterization value BZ, the individual logistics time characterization value DS, and the individual logistics cost characterization value FY into the formula CGX=BZ*a1+DS*a2+FY*a3 to obtain the procurement coefficient CGX, where a1, a2, and a3 are all proportional coefficients, and a1+a2+a3=1;

[0078] Step 6, compare the purchase coefficient CGX with the purchase coefficient threshold YCG:

[0079] When the purchase coefficient CGX is greater than or equal to the purchase coefficient threshold YCG, an emergency purchase signal is generated;

[0080] When the purchase coefficient CGX is less than the purchase coefficient threshold YCG, a normal purchase signal is generated.

[0081] It can be understood that when a stable usage signal is obtained, it means that this type of medical supplies and consumables have not fluctuated during the collection cycle, there will be no rapid consumption in a short period of time, and the inventory is sufficient to meet the next normal procurement cycle, so there is no need for emergency procurement; when an unstable usage signal appears, the procurement coefficient CGX is calculated through the formula, combined with the collection cycle usage characterization value BZ, the separate logistics time characterization value DS, and the separate logistics cost characterization value FY, and the procurement coefficient CGX is compared with the procurement coefficient threshold YCG (the procurement coefficient threshold YCG is set by the staff in this field based on historical data summary). When the procurement coefficient CGX is greater than or equal to the procurement coefficient threshold YCG, an emergency procurement signal is generated; when the procurement coefficient CGX is less than the procurement coefficient threshold YCG, an ordinary procurement signal is generated; because emergency procurement involves procurement time factors and procurement cost factors, by calculating the separate logistics time characterization value DS and the separate logistics cost characterization value FY, and combining the collection cycle usage characterization value BZ to obtain the procurement coefficient CGX, it is possible to more fully consider various factors and make accurate judgments to avoid misjudgment of emergency procurement signals that lead to increased costs or waste of medical supplies and consumables.

[0082] The analysis yields the individual logistics cost representation value FY, which is:

[0083] Obtain the separate logistics freight costs and general procurement and transportation costs of this type of medical supplies and consumables, and use the ratio of the separate logistics freight costs to the general procurement and transportation costs as the separate logistics time representation value DS.

[0084] Specifically, the general purchase and transportation costs can be calculated based on the ratio of the total cost of a purchase to the total number of purchase item types to obtain the average proportion of the transportation costs of this type of medical supplies and consumables for this general purchase, and the general purchase and transportation costs can be obtained. The separate logistics freight costs of this type of medical supplies and consumables can be calculated by ratio with the general purchase and transportation costs to obtain the separate logistics time representation value DS.

[0085] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention.
