Description

Technical Field

[0001] This invention relates to the field of medical data management technology, specifically to a method for managing stressors in hypertensive patients based on meticulous nursing care. Background Technology

[0002] Meticulous nursing care is a patient-centered nursing model that emphasizes detail and individual differences. Building upon routine nursing care, it provides comprehensive and meticulous nursing services to patients through systematic, personalized, and refined methods, aiming to meet patients' health needs and improve the quality of care and patient satisfaction. Especially in managing the various stressors faced by hypertensive patients, nurses not only focus on blood pressure control but also need to assess and manage the patient's psychological state, lifestyle habits, and social support system, thereby reducing patient stress, improving patient compliance, and lowering the risk of disease complications.

[0003] Patients with hypertension are exposed to various stressors, including physiological, environmental, and social stressors. These stressors not only cause fluctuations in blood pressure but also negatively impact mental health, thus worsening the patient's condition. Therefore, it is crucial to identify the specific type of stressor in hypertensive patients and provide targeted care based on that individual stressor. However, current technology does not provide a detailed classification of stress types for hypertensive patients; classification is often based solely on the doctor's subjective judgment, which fails to provide a scientific and effective categorization and management of patients and their corresponding physiological data. Summary of the Invention

[0004] To address the problem that existing technologies do not provide a detailed classification of stress types in hypertensive patients, typically relying solely on doctors' subjective judgments for categorization, which fails to scientifically and effectively classify and manage patients and their corresponding physiological data, this invention aims to provide a stressor management method for hypertensive patients based on meticulous nursing care. The specific technical solution adopted is as follows:

[0005] This invention proposes a method for managing stressors in hypertensive patients based on meticulous nursing care, the method comprising:

[0006] Obtain systolic and diastolic blood pressure signals for each hypertensive patient at different time points;

[0007] In the systolic blood pressure signal, blood pressure stress points are screened out according to the magnitude of systolic blood pressure; within the preset monitoring time range of blood pressure stress points, the short-term stress stimulus compliance of each blood pressure stress point is obtained according to the trend characteristics of the signal; based on the short-term stress stimulus compliance, blood pressure stress points are divided into short-term blood pressure stress points and chronic blood pressure stress points;

[0008] The short-term stress impact on blood pressure of each patient was obtained based on the rate of change in systolic blood pressure at each patient's short-term blood pressure stress point.

[0009] The chronic blood pressure stress point divides the time interval into multiple initial chronic stimulation stages; between adjacent initial chronic stimulation stages, the adjacent initial chronic stimulation stages are merged according to the correlation between the trends of systolic blood pressure changes and the correlation between the trends of diastolic blood pressure changes to obtain multiple complete chronic stimulation stages for the patient; based on the similarity of the complete chronic stimulation stages between different time periods of the patient, the chronic blood pressure stress impact degree of each patient is obtained.

[0010] Patients were classified into multiple first patient clusters based on the impact of short-term and chronic blood pressure stress. Within each first patient cluster, patients were further classified into multiple second patient clusters based on the similarity of the complete chronic stress phases.

[0011] Furthermore, the method for screening blood pressure stress points includes:

[0012] The maximum value of the systolic blood pressure signal that is greater than the preset systolic blood pressure reference threshold is taken as the blood pressure stress point.

[0013] Furthermore, the method for obtaining the short-term stress stimulus conformity includes:

[0014] Within a preset monitoring time range after each blood pressure stress point, the systolic blood pressure value at the blood pressure stress point is used as the upper limit of the level, and the normal baseline level is used as the lower limit of the level. Within the preset monitoring time range, the area of ​​the first region formed by the systolic blood pressure signal and the upper limit of the level is obtained, and the area of ​​the second region formed by the systolic blood pressure signal and the lower limit of the level is obtained. The ratio of the area of ​​the first region and the area of ​​the second region is used as the short-term stress stimulus compliance.

[0015] Furthermore, the normal baseline level of systolic blood pressure is the average systolic blood pressure within a preset second time period before each blood pressure stress point.

[0016] Furthermore, the method for obtaining the short-term stress impact on blood pressure includes:

[0017] For each short-term blood pressure stress point, the ratio of the short-term blood pressure stress point to the systolic blood pressure of the previous signal point in the systolic blood pressure signal is taken as the systolic blood pressure change rate; all short-term blood pressure stress points of each patient are accumulated and normalized to obtain the initial short-term blood pressure stress impact of each patient in each time period; the average initial short-term blood pressure stress impact of all time periods is taken as the short-term blood pressure stress impact of each patient.

[0018] Furthermore, the method for obtaining the complete chronic stimulation phase includes:

[0019] For any two adjacent initial chronic stimulation stages, the systolic blood pressure dimension and diastolic blood pressure dimension are used as the dimensions to be analyzed. The similarity of fluctuation range and fluctuation time between adjacent initial chronic stimulation stages under each dimension to be analyzed is obtained. The correlation between two adjacent initial chronic stimulation stages under each dimension to be analyzed is obtained based on the similarity of fluctuation range and fluctuation time. The average of the correlation between the two dimensions to be analyzed is taken as the overall correlation. If the overall correlation is greater than a preset correlation threshold, it is considered that two adjacent initial chronic stimulation stages can be merged. All initial chronic stimulation stages are traversed to obtain the merging judgment result and obtain the complete chronic stimulation stage.

[0020] Further, obtaining the correlation between two adjacent initial chronic irritation phases under each dimension to be analyzed based on the similarity of the fluctuation intervals and the similarity of the fluctuation time includes:

[0021] The crossover ratio of fluctuation intervals between two adjacent initial chronic stimulation phases is used as the fluctuation interval similarity; the ratio of phase duration between two adjacent initial chronic stimulation phases is used as the fluctuation time similarity; the ratio of phase duration is less than 1; the product of the fluctuation interval similarity and the fluctuation time similarity is used as the correlation.

[0022] Furthermore, the method for obtaining the impact of chronic stress on blood pressure includes:

[0023] The crossover ratio of complete chronic stimulation phases across all time periods is used as the degree of influence of chronic stress on blood pressure.

[0024] Furthermore, the method for obtaining the first patient cluster includes:

[0025] Two-dimensional data consisting of the short-term and chronic stress effects of blood pressure are used as feature data. The Euclidean distance between the feature data of patients is used as a distance metric for clustering to obtain multiple first patient clusters.

[0026] Furthermore, the method for obtaining the second patient cluster includes:

[0027] In the first patient cluster, for any two patients, the correlation coefficient under the intersection of the complete chronic stimulation phase is obtained. Based on the correlation coefficient, the patients are clustered to obtain multiple second patient clusters.

[0028] The present invention has the following beneficial effects:

[0029] This invention first considers the significant fluctuations in systolic blood pressure in response to stressors. Therefore, for each patient, systolic blood pressure is analyzed first to identify blood pressure stress points. Given that the effect of short-term stressors on systolic blood pressure is rapid (i.e., the systolic blood pressure change at short-term stress point locations should exhibit a rapid increase followed by a rapid decrease), short-term and chronic blood pressure stress points can be identified by quantifying the conformity to short-term stressors. The short-term stress impact on the patient's blood pressure is then obtained through the rate of change in systolic blood pressure. For chronic blood pressure stress, the focus is on the synchronicity of the chronic stress impact phases. Stronger synchronicity in the patient's blood pressure stress response across different time periods indicates a greater susceptibility to the influence of chronic stressors. Therefore, complete chronic stress phases are determined through splitting and merging methods. Further analysis of the similarity between different time periods yields the chronic stress impact on each patient's blood pressure. Based on these two stress characteristics, patients can be effectively classified. Further analysis of the similarity across complete chronic stress phases in the initial classification results allows for more refined patient classification, resulting in multiple patient categories in the final outcome. This invention determines the blood pressure stress characteristics of patients in the short and long term based on the changing trends of systolic and diastolic blood pressure, enabling detailed classification of patients and facilitating effective management and targeted care for hypertensive patients.

[0032] To further illustrate the technical means and effects adopted by the present invention to achieve its intended purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation, structure, features, and effects of a stressor management method for hypertensive patients based on meticulous care proposed according to the present invention. In the following description, different "one embodiment" or "another embodiment" do not necessarily refer to the same embodiment. Furthermore, specific features, structures, or characteristics in one or more embodiments can be combined in any suitable form.

[0033] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0034] The following description, in conjunction with the accompanying drawings, details a specific scheme for a stressor management method for hypertensive patients based on meticulous nursing care provided by this invention.

[0035] Please see Figure 1 The diagram illustrates a flowchart of a stressor management method for hypertensive patients based on meticulous care, according to an embodiment of the present invention. The method includes:

[0036] Step S1: Obtain the systolic and diastolic blood pressure signals for each hypertensive patient at different time periods.

[0037] In this embodiment of the invention, patients can use smart wearable devices such as smart bracelets to monitor their blood pressure over a long period of time, and upload the data to the hospital database regularly. The hospital database can then retrieve the electronic medical records of hypertensive patients to obtain systolic and diastolic blood pressure signals at different time periods.

[0038] It should be noted that the time period set in this embodiment of the invention is one day, that is, the blood pressure data of hypertensive patients are obtained every day, and the blood pressure data of three consecutive days are selected for analysis.

[0039] It should be noted that in other embodiments of the present invention, hypertension can be primarily classified into primary hypertension and secondary hypertension. Primary hypertension is often associated with unhealthy lifestyle habits (such as high-salt diets, obesity, and lack of exercise), while secondary hypertension is often related to dysfunction of certain organs (such as diseases of the kidneys, thyroid, or adrenal glands). Both types of hypertension are affected by stressors (such as emotional stress, work pressure, and major life events), which can exacerbate the symptoms of hypertension. This is especially true for secondary hypertension, which is often caused by other diseases or pathological conditions, such as kidney disease or endocrine disorders (such as thyroid problems or adrenal tumors). Stressors activate the sympathetic nervous system, causing the body to secrete more stress hormones (such as adrenaline and cortisol), which lead to elevated blood pressure. Furthermore, stress can also affect the underlying conditions of secondary hypertension, such as worsening kidney dysfunction or endocrine disorders, thereby further affecting blood pressure. Therefore, based on the tags in the electronic medical record, hypertension patients can be initially classified into primary hypertension patients and secondary hypertension patients. These two types of patients are easy to classify and can be directly classified in the initial stage. Subsequent steps only address further classification within one type of hypertension patient. The further classification methods for both types of patients are the same, and will not be repeated in this embodiment of the invention. The following description can be regarded as an explanation only for a certain initially classified type of hypertension patients. It should be noted that, based on the same principle, more initial categories can also be directly classified based on the tags in the electronic medical record in the initial classification stage, which will not be elaborated here.

[0040] Step S2: In the systolic blood pressure signal, blood pressure stress points are screened out according to the magnitude of systolic blood pressure; within the preset monitoring time range of blood pressure stress points, the short-term stress stimulus compliance of each blood pressure stress point is obtained according to the trend characteristics of the signal; based on the short-term stress stimulus compliance, blood pressure stress points are divided into short-term blood pressure stress points and chronic blood pressure stress points.

[0041] For patients with hypertension, different types of hypertension will exhibit corresponding abnormal blood pressure responses within specific time periods after being stimulated by stressors. For example, patients may experience stronger stress during periods of high emotional and work pressure (usually during the day), while other patients may experience blood pressure fluctuations during specific time periods related to their underlying disease (such as in the morning, at night, or when their condition worsens). Only by identifying the time periods corresponding to the abnormal blood pressure responses to stressors can medical personnel better manage and intervene in a targeted manner. Therefore, this invention requires identifying the characteristics of each patient's blood pressure response to short-term stress and chronic stress to effectively classify patients.

[0042] Short-term stressors, such as emotional factors like anger and fear, or physical factors like acute physical discomfort, can cause drastic fluctuations in blood pressure, especially in systolic blood pressure. These short-term stressors cause more pronounced fluctuations, exhibiting rapid high-amplitude fluctuations that quickly return to the normal baseline level.

[0043] Chronic stressors, such as long-term mental stress and persistent emotional fluctuations, can cause patients to experience persistent and gradually rising blood pressure. Unlike short-term stress responses, these blood pressure fluctuations do not drop rapidly but instead present as persistent hypertension over a certain period.

[0044] Based on the characteristics of the two types of stress stimuli described above, this embodiment of the invention considers that short-term stress stimuli have more obvious and easier-to-identify behavioral characteristics, and firstly, short-term stress stimuli behaviors are screened. The first step requires identifying all hypertension data points. Considering that systolic blood pressure is more significant in relation to stress response, blood pressure stress points can be screened from the systolic blood pressure signal based on the magnitude of systolic blood pressure. Because blood pressure stress points may simultaneously include both short-term and chronic blood pressure stress points, the second step can be based on the obvious abrupt rise and fall characteristics of the neighborhood of short-term blood pressure stress points. Based on the trend characteristics of the signal changes, the short-term stress stimulus conformity of each blood pressure stress point can be obtained; that is, the higher the short-term stress stimulus conformity, the more likely the blood pressure stress point is to be a short-term blood pressure stress point. The third step can then use the short-term stress conformity to classify all blood pressure stress points into short-term and chronic blood pressure stress points.

[0045] Preferably, in this embodiment of the invention, the maximum value of the systolic blood pressure signal that is greater than a preset systolic blood pressure reference threshold is taken as the blood pressure stress point. Considering that the diagnostic criteria for adult hypertension is a systolic blood pressure ≥130 mmHg, 130 is used as the systolic blood pressure reference threshold.

[0046] Preferably, in this embodiment of the invention, the method for obtaining short-term stress stimulus conformity includes:

[0047] Because short-term blood pressure stress points are characterized by rapid rises and falls, this embodiment of the invention pre-defines a monitoring time range. If, within this monitoring time range, systolic blood pressure shows a significant downward trend after the blood pressure stress point, it indicates that the stress point is more likely to be a short-term blood pressure stress point, and thus the short-term stress stimulus conformity is greater. Therefore, this embodiment of the invention first uses each blood pressure stress point as a starting point and then sets a monitoring time range after it. This embodiment of the invention sets the monitoring range to 2 minutes.

[0048] Within a preset monitoring timeframe following each blood pressure stress point, the systolic blood pressure value at the stress point is used as the upper limit, and the normal baseline level is used as the lower limit. Within this preset monitoring timeframe, the area of ​​a first region formed by the systolic blood pressure signal and the upper limit is obtained, as well as the area of ​​a second region formed by the systolic blood pressure signal and the lower limit. The first region can be considered a systolic blood pressure easing region, and the second region can be considered a systolic blood pressure stimulation region. That is, a larger first region area and a smaller second region area indicate a significant downward trend in the systolic blood pressure signal within the current monitoring timeframe, which better matches the characteristics of short-term stress stimulation. Therefore, the ratio of the first region area to the second region area is used as the short-term stress stimulation conformity.

[0049] It should be noted that the area enclosed by the signal curve and its upper and lower limits can be obtained using basic mathematical methods such as definite integrals, which will not be elaborated further.

[0050] Furthermore, in one embodiment of the present invention, considering that patients are affected by multiple factors such as circadian rhythms (generally, blood pressure is higher during daytime activity and lower during nighttime rest) and daily temperature changes, the baseline level of systolic blood pressure varies at different times of the day, and this difference is within the normal range for each individual. Therefore, the normal baseline level of systolic blood pressure needs to be set according to the patient's real-time status. In this embodiment of the present invention, the normal baseline level of systolic blood pressure is the average systolic blood pressure within a preset second time period before each blood pressure stress point. That is, considering that short-term stress points are sudden stimuli, the systolic blood pressure information before the stimulation should be the patient's normal systolic blood pressure information. Therefore, information within a preset second time period before the blood pressure stress point can be selected for statistical analysis. In this embodiment of the present invention, the second time period is set to 5 minutes.

[0051] In this embodiment of the invention, after normalizing the short-term stress stimulus compliance, the short-term stress stimulus compliance threshold is set to 0.75. Blood pressure stress points with normalized short-term stress stimulus compliance greater than the short-term stress stimulus compliance threshold are taken as short-term blood pressure stress points, and other blood pressure stress points are taken as chronic blood pressure stress points.

[0052] It should be noted that the normalization method in the embodiments of the present invention can employ range standardization. Normalization eliminates dimensions and limits the value range of the data to between 0 and 1 in its own dimension. Other normalization methods can also be selected in other embodiments of the present invention, which will not be elaborated here.

[0053] Step S3: Obtain the short-term stress impact of blood pressure for each patient based on the rate of change in systolic blood pressure at the short-term blood pressure stress point.

[0054] For short-term blood pressure stress points, the greater the rate of change in systolic blood pressure at that location, the stronger the patient's response after being stimulated at that short-term blood pressure stress point, and the greater the impact of short-term blood pressure stress.

[0055] Preferably, in one embodiment of the present invention, for each short-term blood pressure stress point, the ratio of the systolic blood pressure at the short-term blood pressure stress point to the systolic blood pressure at the previous signal point is used as the systolic blood pressure change rate. All short-term blood pressure stress points for each patient are accumulated and normalized to obtain the initial short-term blood pressure stress impact for each patient in each time period. Because this embodiment of the present invention collects information from multiple time periods, the average initial short-term blood pressure stress impact across all time periods is used as the short-term blood pressure stress impact for each patient.

[0056] Step S4: The chronic blood pressure stress point divides the time interval into multiple initial chronic stimulation stages; between adjacent initial chronic stimulation stages, the adjacent initial chronic stimulation stages are merged according to the correlation between the trends of systolic blood pressure changes and the correlation between the trends of diastolic blood pressure changes to obtain multiple complete chronic stimulation stages for the patient; based on the similarity of the complete chronic stimulation stages between different time periods of the patient, the chronic blood pressure stress impact degree of each patient is obtained.

[0057] For chronic stress, the main focus is on assessing the synchronicity of the patient's response to such stimuli. If the patient experiences a stress response at the same time every day, it indicates that the patient's response to chronic stimuli is relatively sensitive and severe, requiring targeted care.

[0058] To analyze the stages of chronic stimulation, the time interval of a signal can first be divided into multiple initial chronic stimulation stages, which can be considered as chronic blood pressure stress points. Then, adjacent initial chronic stimulation stages can be merged based on the correlation between the trends of systolic and diastolic blood pressure changes. When blood pressure is continuously affected by the same stressor, its fluctuations usually remain within a relatively stable range and exhibit temporal continuity. By comparing the similarity of the blood pressure fluctuation range and the degree of matching of the fluctuation duration between adjacent initial chronic stimulation stages, it is possible to effectively determine whether these two initial chronic stimulation stages are under the influence of the same stressor. That is, for two adjacent initial chronic stimulation stages, similar trends in diastolic and systolic blood pressure changes indicate that the two initial chronic stimulation stages should be the same stage. Therefore, the merging relationship of all adjacent initial chronic stimulation stages can be determined based on this, and by merging, multiple complete chronic stimulation stages of the patient within a certain time period can be obtained. Further analysis can be conducted to determine the similarity of complete chronic stress phases across different time periods for each patient, thereby obtaining the chronic stress impact on blood pressure for each patient. The greater the similarity, the stronger the synchronicity of the complete chronic stress phases across different time periods, indicating that the patient has a significant chronic stress response and a greater chronic stress impact on blood pressure.

[0059] Preferably, in this embodiment of the invention, the analysis methods for both systolic and diastolic blood pressure are the same when analyzing adjacent initial chronic irritation phases; therefore, the method for obtaining complete chronic irritation phases includes:

[0060] For any two adjacent initial chronic stimulation phases, the systolic blood pressure and diastolic blood pressure dimensions are used as the dimensions to be analyzed. The similarity of fluctuation ranges and fluctuation durations between adjacent initial chronic stimulation phases under each dimension is obtained. Based on these similarities, the correlation between two adjacent initial chronic stimulation phases under each dimension is determined. That is, under a given dimension, the more similar the fluctuation ranges and the more similar the phase durations of two initial chronic stimulation phases, the greater the correlation under that dimension.

[0061] The correlation between the two dimensions to be analyzed is averaged as the overall correlation. If the overall correlation is greater than the preset correlation threshold, it is considered that two adjacent initial chronic irritation stages can be merged. All initial chronic irritation stages are traversed to obtain the merging judgment result and obtain the complete chronic irritation stage.

[0062] In this embodiment of the invention, after normalizing the overall correlation, the correlation threshold is set to 0.75.

[0063] Furthermore, based on the similarity of the fluctuation intervals and the similarity of the fluctuation time, the correlation between two adjacent initial chronic irritation phases under each dimension to be analyzed is obtained, including:

[0064] The crossover ratio (CVR) between two adjacent initial chronic stimulation phases is used as the fluctuation interval similarity. A larger CVR indicates a greater degree of overlap between the two fluctuation intervals, and thus a greater similarity between the fluctuation intervals in the dimension under analysis.

[0065] The ratio of the duration of two adjacent initial chronic irritation phases is used as the fluctuation time similarity; the ratio of the duration of the phases is less than 1. That is, the ratio is the smaller value divided by the larger value. The closer the ratio is to the maximum value of 1, the more similar the durations of the two phases are.

[0066] The product of the fluctuation interval similarity and the fluctuation time similarity is taken as the correlation.

[0067] Preferably, in this embodiment of the invention, the method for obtaining the impact of chronic stress on blood pressure includes:

[0068] The crossover ratio of complete chronic stimulation phases across all time periods is used as the degree of influence of chronic stress on blood pressure.

[0069] It should be noted that intersection-union ratio is a technical means well known to those skilled in the art, and will not be elaborated here.

[0070] Step S5: Classify patients according to the short-term stress impact and chronic stress impact of blood pressure to obtain multiple first patient clusters; classify patients in the first patient clusters according to the similarity of the complete chronic stress phase to obtain multiple second patient clusters.

[0071] Based on the analysis described above, each patient possesses characteristics across two dimensions. Therefore, each patient can be treated as a data point in a two-dimensional space for cluster analysis, resulting in multiple first patient clusters. Furthermore, for each first patient cluster, patients within that cluster are further subdivided based on their complete chronic stress phase. This is because chronic stressors can cause patients to experience abnormal blood pressure at different times, and patients experiencing the same or adjacent stressors (such as work hours) may correspond more frequently to the same stressor. This allows for more targeted and meticulous nursing care. Therefore, within the first patient clusters, patients are classified according to the similarity of their complete chronic stress phases, resulting in multiple second patient clusters. This detailed subdivision leads to multiple patient categories.

[0072] Different types of stressors have different effects on a patient's physiological and psychological state. Short-term stressors may require short-term adjustments to alleviate them, while long-term stressors may require long-term psychological intervention, lifestyle changes, or medication. By classifying hypertensive patients, doctors can develop personalized treatment plans based on the characteristics of the stressors they face, thus managing and controlling blood pressure more effectively. Tailoring individualized management strategies for each patient type—for example, for patients with hypertension caused by work stress, the focus might be on adjusting the work environment and time management, while for those with hypertension caused by family problems, the focus might be on psychological intervention and improving family communication skills—can achieve precise intervention, improving treatment outcomes and avoiding a one-size-fits-all approach.

[0073] Preferably, in this embodiment of the invention, the method for obtaining the first patient cluster includes:

[0074] Two-dimensional data comprising the short-term and chronic stress impacts of blood pressure are used as feature data. The Euclidean distance between the feature data of patients is used as a distance metric for clustering to obtain multiple first patient clusters. It should be noted that the clustering method can be DBSCAN clustering, and other methods may be used in other embodiments; this is not limited here.

[0075] Furthermore, the methods for obtaining the second patient cluster include:

[0076] Within the first patient cluster, for any two patients, the correlation coefficient under the intersection of the complete chronic stimulation phases is obtained. Based on this correlation coefficient, the patients are clustered to obtain multiple second patient clusters. The correlation coefficients are obtained using Jaccard's algorithm; the specific clustering method will not be elaborated further.

[0077] In summary, this invention first analyzes systolic blood pressure for each patient, identifying blood pressure stress points. Then, it quantifies the conformity of short-term stress stimulation to further identify both short-term and chronic blood pressure stress points. The short-term stress impact on blood pressure is then obtained through the rate of change in systolic blood pressure. By using a splitting and merging method to determine the complete chronic stress phase, further analysis of the similarity between different time periods yields the chronic stress impact on blood pressure for each patient. Based on these two stress characteristics, patients can be effectively classified. Furthermore, by considering the similarity of the complete chronic stress phase in the initial classification results, a more refined classification of patients can be achieved, resulting in multiple patient categories in the final outcome. This invention determines the short-term and long-term blood pressure stress characteristics of patients based on the trends in systolic and diastolic blood pressure, enabling detailed patient classification and facilitating effective management and targeted care for hypertensive patients.

The processes depicted in the accompanying drawings do not necessarily require a specific or sequential order to achieve the desired result.
