the financial terminal encrypts the number of people discharged from each hospital department, the hospitalization cost and the hospitalization medical income with medicines and consumables deducted by using the received public key based on the received medical data acquisition request, and then sends the encrypted public key to the server through a TCP (transmission control protocol);
the hand anesthesia terminal encrypts the three-fourth-level operation cases and the total operation cases of each hospitalized department by using the received public key based on the received medical data acquisition request, and then sends the encrypted results to the server through a TCP (transmission control protocol);
the department terminal encrypts the number of primary care cases, the number of special care cases, the number of intensive care cases, the bed occupation date, the amount of consultation from a clinician to each hospital department, the amount of heavy rescue and the amount of emergency department transfer patients by using the received public key based on the received medical data acquisition request, and then sends the encrypted public key to the server through a TCP protocol.
6. The system according to claim 3 or 5, wherein the risk factor evaluation system based on public-private key encryption comprises: the risk coefficient evaluation module specifically comprises:
the server decrypts the received medical data by using the private key to obtain the number of people discharged from hospital, the hospitalization cost, the hospitalization medical income with medicines and consumables deducted, the number of third-fourth-level operation cases, the number of total operation cases, the number of first-level nursing cases, the number of special-level nursing cases, the number of intensive care cases, the bed occupation date, the consultation amount from a clinician to each hospitalization department, the large rescue amount and the patient amount in an emergency department;
the server scores the medical income proportion of each discharged person by using the evaluation rule to generate a first score; the medical income per discharge is equal to the medical income per discharge/the medical income per discharge; the medical income cost per discharge is equal to the medical income/discharge times of hospitalization; the cost of each person who is discharged is equal to the hospitalization cost/the number of persons who are discharged;
the server scores all the three-level and four-level operation proportions by using the evaluation rule to generate a second score; the three-four stage operation ratio is three-four stage operation example number/total operation example number;
the server scores all the comprehensive nursing amounts by using the evaluation rule to generate a third score; the comprehensive care amount is (number of primary care cases + number of special care conversion × 1.2+ number of intensive care conversion × 1.5)/day of bed occupation; the special nursing conversion number is the number of special nursing cases/24; the intensive care conversion number is the number of intensive care cases/24;
the server scores each consultation amount by using the evaluation rule to generate a fourth score;
the server scores all the large rescue quantities by using the evaluation rule to generate a fifth value;
the server scores the patient quantity of each emergency department transfer room by using the evaluation rule to generate a sixth score;
the server calculates a risk coefficient based on the first score, the second score, the third score, the fourth score, the fifth score, the sixth score and the weight coefficient:
surgical department risk factor ═ first score a 1% + second score a 2% + third score a 3% + fourth score a 4% + fifth score a 5% + sixth score a 6%;
non-surgical department risk factor + b 1% + b 2% + b 3% + b 4% + b 5% + b 6%.
7. The system of claim 1, wherein the risk factor evaluation system based on public-private key encryption comprises: the one-time programmable memory is eFuse memory or OTP memory.
8. The system of claim 1, wherein the risk factor evaluation system based on public-private key encryption comprises: the financial terminal, the hand anesthesia terminal and the department terminal are mobile phones, tablet computers, notebooks or desktop computers.
9. An outpatient and emergency department risk factor assessment device comprising a memory, a processor and a computer program stored on the memory and executable on the processor, wherein the processor when executing the program implements a system according to any one of claims 1 to 8.
10. An outpatient and emergency department risk factor evaluation medium having a computer program stored thereon, wherein the program, when executed by a processor, implements a system according to any one of claims 1 to 8.
