2. Description of the Related Art Conventionally, in order to improve the working environment for workers, efforts have been made to evaluate the degree of fatigue of workers so that physical and mental burdens on workers do not accumulate. As such a technique, for example, a stress check is known in which a worker answers questions and diagnoses the degree of stress (see Patent Document 1). In addition, a system that predicts turnover based on work performance (see, for example, Patent Document 2), and an operator work performance visualization system that visualizes and manages shift work performance and fatigue levels (see, for example, Patent Document 3) have been proposed. there is

JP 2016-207165 A JP 2016-136380 A JP 2018-45481 A

However, stress checks are based on the subjectivity of individual workers, and if they are reflected in work plans based on subjectivity, they are not necessarily realistic. you can't. In addition, job separation prediction is based on the results of past job separations, and the cause is not only the degree of fatigue, but the degree of fatigue of workers and their groups cannot be objectively evaluated. Visualization of shift work record and fatigue level is a combination of information on actual work hours and actually detected biological information, and can evaluate fatigue level according to individual characteristics of workers. However, it is necessary for each worker to wear a biological information acquisition band such as heart rate and blood pressure, and the system configuration is complicated. There is also psychological fatigue, and it is not possible to objectively evaluate such things.

Hereinafter, embodiments of the fatigue evaluation system and the fatigue evaluation program of the present disclosure will be described based on the drawings.

(Embodiment 1)
A fatigue level evaluation system A that performs fatigue level evaluation using the fatigue level evaluation program of the first embodiment includes an input unit 10, a fatigue level evaluation calculation processing unit 20, and an output unit 30, as shown in FIG. This fatigue evaluation system A is a system that evaluates the degree of fatigue for a group of workers or an individual worker in a population consisting of a plurality of workers who perform shift work in different working hours. .

In the following description, a hospital is shown as an example of a shift work workplace evaluated by the fatigue evaluation system A. Next, a case will be described in which the degree of fatigue is evaluated for a group consisting of a plurality of workers or for a single worker in a population consisting of a plurality of workers in a hospital or ward. In addition to hospitals, other workplaces such as factories, police, and fire departments can also be applied as shift work workplaces to be evaluated.

First, before describing the fatigue evaluation system A of Embodiment 1, the working style of a hospital will be described. FIG. 2 shows an example of hospital work data, and FIG. 3 shows an example of hospital shift data.

As shown in Fig. 3, the work shift patterns of the hospital to be evaluated are day shift (indicated as "day" in Fig. 2), semi-night shift (indicated as "quasi" in Fig. 2), late-night shift (indicated as "deep" in Fig. 2). ”) and nursing student work (indicated as “Academic” in FIG. 3) are set. In this example, the day shift is defined as work in a working time zone with a start time of 8:30 and an end time of 17:30. In addition, semi-night shifts are defined as working hours that start at 16:30 and end at 25:30. Late-night shifts are defined as work hours that start at 00:30 and end at 9:30. Nursing student duty starts at 8:30 and ends at 20:00, and has a non-working time zone during which the student attends a nursing school. Nursing student work is excluded from the data in Figure 2 as it is not included in the evaluation target.

The work data shown in FIG. 2 indicates work shifts in the work plan that are set before actually working. In the work data shown in FIG. 2, "holiday" indicates a holiday, and "available" indicates a paid vacation. Further, in FIG. 2, the workers whose names are FF and GG are those who specialize in the night shift (indicated as "dedicated"). Since the aim is to distribute the numbers fairly so that there is no imbalance, such workers are excluded from the evaluation targets, as are nursing students.

Next, the fatigue evaluation system A shown in FIG. 1 will be described.
The input unit 10 is connected to the communication network NW. The communication network NW includes a limited area network such as a so-called LAN (local area network) and a wide area network such as a public line.

The input unit 10 inputs the work data shown in FIG. 2 and the shift data shown in FIG. This input can be input via the communication network NW or the like. For example, when a processing device such as a computer or a server that creates and records work schedules and work records is connected to a communication network NW, input is made via this communication network NW. Data can also be input using a predetermined recording medium. Alternatively, the fatigue evaluation system A may have a program for creating a work plan and a storage unit for recording the work plan and work performance. Work data is input from the storage unit that stores the data of . Furthermore, when a worker wants to personally and objectively evaluate his/her degree of fatigue, the worker can use a portable terminal such as a mobile phone to input personal work data.

In the case of a work plan, the work data is read in units of a predetermined period such as one month or one week. Moreover, when the work data is the work record, it may be input every day, or may be input in units of a predetermined period such as one month or one week. Note that once the shift data is input and stored, there is no need to read it again unless there is a change in the regulations of each working hour.

The fatigue level evaluation calculation processing unit 20 is a so-called computer having a CPU, a RAM, and a ROM, and performs processing for evaluating accumulated fatigue levels based on the fatigue level evaluation program of the first embodiment. As shown in FIG. 1, the fatigue evaluation calculation processing unit 20 includes a data storage unit 21, a fatigue calculation unit 22, a fatigue integration unit 23, and an output control unit .

The data accumulation unit 21 stores and accumulates work data, shift data, and the like read by the input unit 10 . The data accumulation unit 21 is a so-called memory, and accumulates not only work data and shift data but also a calculated degree of fatigue and an integrated value of degree of fatigue, which will be described later.

The fatigue level calculator 22 calculates the worker's fatigue level for a predetermined period based on the work data and the shift data. The duty constraint time, work interval, and fatigue influence points are used for the calculation of the degree of fatigue.

The work commitment time is the time from the work start time to the work end time. When the work schedule is used as the work data, the work commitment time is obtained based on the time in the shift data. When working record is used as work data, it is calculated using the actual work start time and work end time.

The work interval is the interval between the end of work and the start of the next work. In this case as well, when the work schedule is used as work data, the work interval is obtained based on the work start time and work end time in the shift data, and when work performance is used as work data, the actual work Calculated using the start time and work end time.

The fatigue impact point BP is a point given in consideration of fatigue when the worker performs a work style that may cause physical or psychological fatigue. This fatigue effect point BP is given according to the number of times of duty of the fatigue work item described later that is set in advance according to the degree of fatigue. Give "1" point. In addition, the value of the fatigue effect point given to one work of this fatigue work item is not limited to "1". can be set to

Here, fatigue work items include night shift work, early work, and reverse cycle shift work in this embodiment. Night shift work is work that requires a predetermined night shift time (for example, between 22:00 and 5:00) during a fixed time. Early departure work is work whose work start time includes a predetermined early start time (a time between 5:00 and 7:00). Reverse circular shift work is work in which the interval between the start time of the next shift work and the start time of the previous shift work is less than 24 hours, and the shift is in the direction of narrowing the work interval.

Then, the fatigue degree calculation unit 22 increases (rises) in accordance with the work constraint time and subtracts (decreases) it in accordance with the work interval. value) Calculate so that Fdup becomes large.

Specifically, the increased value (increased value) Fdup of the degree of fatigue is calculated by Equation 1 below.
Fdup=duty hours×(1.2+BP×K) (Equation 1)
Note that in the first embodiment, K=0.1. In addition, the increase value Fdup is obtained by multiplying the work commitment time by 1.2 except for the night shift work, the early work shift, and the reverse circulation shift work that give the fatigue influence point BP.
Also, the decrease value (decrease value) Fddn of the degree of fatigue is calculated by Equation 2 below.
Fddn=work interval×0.5 (formula 2)

The fatigue level calculation unit 22 calculates the fatigue level for each day based on the formulas 1 and 2 above. This one day is calculated based on the duty time from 0:00 to 24:00, the work interval, and the fatigue effect point BP according to the shift work at that time. The lower limit of the degree of fatigue is set to "0". For example, when the fatigue degree decrease value (fall value) Fddn exceeds the fatigue degree increase value (increase value) Fdup, the fatigue degree is not set to a negative value but is set to “0”. In addition, the fatigue effect point BP is reset to "0" when the date difference from the start time of the work interval reaches 3 days.

The fatigue degree accumulating unit 23 accumulates the fatigue degree corresponding to the shift work of each worker calculated by the fatigue degree calculating unit 22 in a preset period, and also accumulates the fatigue degree to be evaluated in the preset period. . For example, when a work plan for one month is created and the degree of fatigue is calculated using this work plan as work data, the preset period is one month. Also, if the actual work record is used as the work data, the integrated value may be obtained, for example, every week or every month. In short, this preset period may be arbitrarily set according to how to use the fatigue level evaluation.

Also, the evaluation target may be one worker or a group of workers. This group may be, for example, a group of workers in a ward of a hospital, or a group of workers in a certain department in a hospital ward. In this way, when the fatigue level is calculated for a group of a plurality of workers to be evaluated, the average value of each worker is used to calculate the fatigue level for the evaluation target.

Furthermore, if the employee takes two consecutive days off (48 hours that does not include work commitment time), the integrated value of the degree of fatigue is reset to "0". That is, it is assumed that fatigue is recovered after 48 hours of rest.

The output control unit 24 outputs the fatigue level integration result of the fatigue level integration unit 23 through the output unit 30 . In Embodiment 1, a display device for displaying on a screen is used as the output unit 30, and FIGS. 5A and 5B show examples of the output.

The fatigue evaluation display unit 300 on the screen of the display device displays the integrated value of the fatigue degree in a line graph with the date of one month as the horizontal axis and the fatigue degree and the fatigue influence point as the vertical axis. Display the points as a bar graph.

Next, based on the flowchart shown in FIG. 4, the flow of fatigue evaluation processing by the fatigue evaluation calculation processing unit 20 will be described.

First, in the first step S101, data is read from the input unit 10 to the data storage unit 21 and stored. This data includes work data such as work plans and work records shown in FIG. 2 and shift data as shift pattern data shown in FIG. In addition, the work record includes time data such as overtime hours other than the hours according to the shift pattern and hours of leaving early.

In the next step S102, the fatigue degree calculation unit 22 calculates the work commitment time, work interval, and fatigue effect points of each worker in the hospital as a population from the read data. Then, in the next step S103, the degree of fatigue of each worker on each day is calculated based on the work restraint time, work interval and fatigue effect points of each worker.

Furthermore, in the next step S104, the daily fatigue level of each worker calculated by the fatigue level integrating section 23 is integrated over a predetermined period. In the first embodiment, the predetermined period for accumulating the degree of fatigue is one month.

Then, in the next step S105, the calculation result is output to the output unit 30 and displayed on the display unit 300 of the screen of the display device. As shown in FIGS. 5A and 5B, the display unit 300 displays the value obtained by accumulating the degree of fatigue for each day as a line graph. Further, the display unit 300 displays the fatigue effect point BP as a bar graph representing the magnitude of the value on the day when it is given as the height in the direction along the vertical axis.

(Action of Embodiment 1)
To explain the operation of the embodiment, a case where a work schedule for one month is input as work data, a population of workers in the entire hospital is used, and a fatigue level is calculated for a group of workers in a certain ward as an evaluation object. An example is shown in FIGS. 5A and 5B.

FIG. 5A shows a case where the degree of fatigue is calculated from work data of an ideal work plan. That is, in this example, although the value of the line graph indicating the integrated value of the degree of fatigue fluctuates, it becomes "0" at the end of the month, and the degree of fatigue is kept low throughout the month. Formulas 1 and 2 used by the fatigue level calculation unit 22 to calculate the fatigue level in the first embodiment, and the fatigue effect point BP are obtained by: An ideal work pattern is set so that the degree of fatigue becomes "0" when such shift work is performed.

On the other hand, FIG. 5B shows the case where work data of an unfavorable work plan is input, and the value of the line graph showing the integrated value of the fatigue level rises significantly at the end of the month, indicating that the fatigue level of the ward workers has increased significantly. For example. For example, if there is an imbalance in shift work, or if the work constraint time of each worker becomes longer due to a shortage of personnel, or if shift work that is given fatigue impact points BP overlaps, the fatigue level of multiple workers increases as shown in FIG. 5B.

As described above, in the first embodiment, the degree of fatigue over the month can be objectively viewed from the line graph. Therefore, when a work plan is created and the accumulated fatigue is evaluated, if the evaluation result shown in FIG. can be achieved. For example, the work plan resulting from such improvements can be viewed as the work plan shown in FIG. 5A.

Also, although an example of reading a work schedule as work data has been described, it is also possible to read work records as work data. Then, when the work record is read and the accumulated fatigue evaluation shown in FIG. Improvements can be made. As a result, it is possible to prevent the occurrence of troubles before the degree of fatigue of the workers in the ward to be evaluated increases and troubles caused by fatigue occur.

(Effect of Embodiment 1)
The effects of the fatigue evaluation system A of the first embodiment are listed below.
(1) The fatigue evaluation system A of the first embodiment is
An input unit 10 for data relating to the work of multiple workers who work shifts in different working hours, and a fatigue level evaluation calculation processing unit 20 for evaluating the fatigue level of one or more workers based on the data. And a fatigue evaluation system comprising an output unit 30 that outputs evaluation results,
The input unit 10 receives, as data, shift pattern data defining a plurality of types of working hours, and work data including the work start time and work end time of each worker,
Based on the data, the fatigue level evaluation calculation processing unit 20 adds the fatigue level of the worker for a predetermined period according to the duty time, subtracts it according to the work interval, and furthermore, according to the duty time. The added value is calculated using the fatigue level calculation unit 22 that is calculated using a preset value considering the fatigue level based on the type of shift work and the working hours, and the fatigue level of each worker calculated by the fatigue level calculation unit 22. Based on this, a fatigue degree accumulating unit 23 for accumulating the fatigue degree of an evaluation object for a preset period, and an output control unit 24 for outputting the accumulation result of the fatigue degree from the output unit 30 are provided.

Therefore, as the fatigue level, the physical fatigue level can be calculated with high accuracy based on the addition according to the duty time and the subtraction according to the work interval. That is, it is possible to calculate the degree of fatigue in line with the actual degree of fatigue in consideration of recovery from fatigue during work intervals. Furthermore, the additional value according to the work commitment time is calculated based on a preset value considering the type of shift work and the degree of fatigue based on the working hours, so that the degree of fatigue is not only physical fatigue. In addition, the degree of psychological fatigue can be objectively evaluated. In addition, in Embodiment 1, when the ideal shift work is performed, the integrated value of the degree of fatigue becomes "0", so the degree of fatigue can be evaluated more realistically.

(2) The fatigue evaluation system A of the first embodiment is
The data includes at least one of data based on work plans and data based on actual work results.

Therefore, when a work plan is input as data, it is possible to objectively recognize the degree of fatigue when the work plan is executed, and based on this, it is possible to improve the work plan. On the other hand, when the work record is input as data, the actual fatigue level of the subject to be evaluated for the month can be objectively recognized. Therefore, when the integrated value of the degree of fatigue rises to a certain extent, it is possible to improve the work plan and avoid the occurrence of problems due to the increased degree of fatigue.

(3) The fatigue evaluation system A of the first embodiment is
As a preset value considering the degree of fatigue, a fatigue impact point is set by multiplying the duty time. If the duty time includes night shift hours, the fatigue effect point is when the work start time is a predetermined early morning time. In at least one of the case of being included in the belt and the case of shifts with narrow working intervals, the degree of fatigue is given to be high.

Night shifts tend to cause more physical and psychological fatigue than day shifts. It is also said that early morning shifts and shifts with narrow work intervals increase physical and psychological fatigue and disrupt biorhythms. Therefore, by using a value to be added as the degree of fatigue according to the situation of such shift work, it becomes possible to evaluate the degree of fatigue with higher accuracy.

(4) The fatigue evaluation system A of the first embodiment is
The workers are hospital workers, and at least day shift, semi-night shift, and late night shift are set as working hours, and evaluation targets are a plurality of workers working in one hospital ward.
Therefore, it is possible to objectively calculate the general fatigue level of a plurality of workers working in a ward of a hospital with high accuracy. By calculating and evaluating the degree of fatigue of the workers in the entire hospital ward in this way, it is possible to appropriately plan the work of the workers in the entire hospital ward.

(5) The fatigue level evaluation program of the first embodiment is
Data related to the work of multiple workers who work shifts in different working hours, including shift pattern data that defines the types of multiple working hours and work data that includes the start time and end time of work for each worker. and an input unit 10 for inputting, a fatigue level evaluation calculation processing unit 20 for evaluating the fatigue level of one or more workers as evaluation targets based on the data input to the input unit 10, and outputting the evaluation result. A fatigue evaluation program executed by a fatigue evaluation system comprising an output unit 30,
Based on the data, the fatigue level evaluation calculation processing unit 20 adds the fatigue level of the worker for a predetermined period according to the duty time, subtracts it according to the work interval, and further calculates it according to the duty time. The additional value is calculated in steps S102 and S103 using a preset value considering the fatigue level based on the type of shift work and working hours, and the preset period based on the calculated fatigue level of each worker. Step S104 of accumulating the fatigue degree of the evaluation object and Step S105 of outputting the accumulation result of the fatigue degree from the output unit 30 are executed.

Therefore, as the degree of fatigue, it is possible to calculate the degree of physical fatigue with high accuracy based on the addition according to the work restraint time and the subtraction according to the work interval. Furthermore, the additional value according to the work commitment time is calculated based on a preset value considering the type of shift work and the degree of fatigue based on the working hours. As a result, the degree of psychological fatigue can be objectively evaluated.

Although the embodiment of the present invention has been described in detail with reference to the drawings, the specific configuration is not limited to this embodiment. Included in the invention.

For example, in the embodiment, an example of evaluating the degree of fatigue of a hospital worker has been described, but the place of work is not limited to a hospital. In short, the present invention can be applied to work load evaluation of workplaces other than hospitals, such as factories, restaurants, police stations, and fire departments, as long as they have work shifts with different working hours.

In addition, in the embodiment, night shift work, early work shift, and reverse cycle shift work are shown as examples of assigning fatigue effect points BP, but the present invention is not limited to these. That is, since the degree of fatigue based on the type of shift work and working hours varies depending on the type of work and work environment, shift work that gives a value (fatigue effect point BP) set in consideration of these degrees of fatigue can be set arbitrarily. can do. In addition, the relationship between this value (fatigue effect point BP) and work commitment time can be arbitrarily set according to the type of job and work environment, and is limited to formula 1 and formula 2 shown in the embodiment. Any calculation method can be used instead of

In addition, the additional value of fatigue level according to the work constraint time and the subtraction value of fatigue level according to the work interval are set based on the measured values that are related to the actual fatigue level. or can be corrected. For the value related to the actual fatigue level, for example, information about heart rate or subjective fatigue level information can be used. Further, as the subjective fatigue level information, for example, a fatigue VAS (Visual Analogue Scale) or fatigue evaluation using a Numerical Rating Scale (NRS) can be used.

Also, in the embodiment, the display screen used by the administrator is shown as the output unit, but the output unit is not limited to this. For example, it can be printed out, output to a storage medium, or output to a mobile terminal, server, or the like possessed by the worker via the communication network NW. In addition, it is also possible for workers to objectively evaluate their own degree of fatigue as an evaluation target. It is also possible to evaluate using a fatigue evaluation program and display it on a personal computer or mobile terminal.

Furthermore, if the work record is used as the data, some kind of notification output may be performed when the integrated value of the degree of fatigue exceeds a predetermined value. For example, when the occurrence of an event that could lead to an accident or its discovery (hereinafter referred to as a near miss) is associated with the integrated value of the fatigue level, and if the relationship between the two is found, a notification output is performed in advance, and the near miss It is possible to prevent the occurrence of

Specifically, based on the curve of the accumulated fatigue level shown in FIG. 5A and FIG. can calculate the risk of Then, the date and time of near-miss occurrence and the fatigue degree integrated value curve of any interval before that are taken out, and the near-miss occurrence frequency for each fatigue degree integrated value curve is recorded and accumulated. Furthermore, based on the accumulated data, it is possible to discover in advance that there is a possibility of occurrence of a near-miss with respect to work plans and work records that include curves of similar integrated values of fatigue levels.

Therefore, when creating a work plan, if there is a possibility of occurrence of such a near miss, it is possible to reduce the possibility of occurrence of a near miss by recreating a work plan that suppresses the degree of fatigue. In addition, by inputting work records every day, it is possible to discover in advance that there is a possibility of occurrence of a near miss, and to avoid or suppress the occurrence of a near miss.
