Inclusion criteria: dialysis treatment started more than 2 months ago; hemodialysis was conducted three times a week; there was no language communication and cognitive impairment, and they could express their wishes accurately; the patients had informed consent. Exclusion criteria: patients with Alzheimer's disease or other mental disabilities; patients with malignant tumors; patients with a history of mental illness; patients with limb paralysis; patients who refused to participate in this study. The investigation time is from 2020.2.1 to 2020.7.1.
1.2 Methods
1.2.1 Symptom Checklist90 (SCL-90)
SCL-90 scale is the most widely used psychological disease examination scale at present. It involves from feeling, emotion, thinking, consciousness, behavior to living habits, interpersonal relationship, diet and sleep, including 9 subscales with 90 items, which were divided into 10 categories, namely 10 factors: somatization (reflecting subjective physical maladaptation), obsessive-compulsive symptoms, interpersonal sensitivity, depression, anxiety, hostility, paranoia, psychosis, and additional factors (reflecting sleep and appetite). Scoring criteria: a five-grade scoring system (from 1 to 5) was adopted, from none to serious. Add the scores of each item of 90 items to get the total score. Total average score = total score / 90. Factor score = the total score of each item constituting a factor / the number of items constituting a factor. The score range is 1–5, the lowest is 1, and the highest is 5. The higher the score, the more obvious the symptoms [6] and the worse the mental health.
1.2.2 Refined Nursing Intervention Methods
1.2.2.1 Nursing intervention before dialysis
(1) Improve the nursing concept To implement a refined nursing model for maintenance hemodialysis patients, it is necessary to start with improving the nursing concept of the nursing staff. The nursing staff adhere to the principle of precision and refinement in the process of nursing intervention, be careful in their daily work and miss no details. They need to have the right work attitude and provide patients with high-quality nursing services. The center cancels collective shifts and holds group work meetings twice a day. The head nurse personally presides over the meeting. Each group leader participates in the meeting. The head nurse conveys the department's prevention and control requirements during the novel coronavirus epidemic and analyzes the spirit of related policies. The current difficulties faced by the team, urgent problems to be resolved, changes in critically ill patients' condition, difficult vascular access, and other issues were put forward by group leader at the meeting to jointly study solutions, and according to the dynamic changes of the epidemic situation, the problems in the management are analyzed and continuously improved. Among the problems reported by each group, more than 90% are the psychological pressure caused by the epidemic on dialysis patients, causing the patients to have negative psychological emotions. In response to this problem, the head nurse leads the nurses to conduct psychological counseling for dialysis patients, correct their negative psychological emotions and resolve contradictions. Do what should be done today, handle the problem in the bud, effectively relieve the psychological pressure of patients, and ensure the normal progress of hemodialysis treatment.
(2) Strengthen the training of nursing staff If the professional level of nursing staff is not up to standard, it will hinder the implementation of fine nursing model. Therefore, the department regularly strengthens the training of nursing staff. The training content is mainly based on theoretical knowledge and clinical nursing practice. While enriching the nursing staff's theoretical knowledge, improve the nursing staff's clinical practice ability, and improve the nursing staff's professional quality as a whole. During the epidemic, all medical staff of blood purification participated in the COVID-19 related trainings in Beijing and the hospital as required and met the standards.
(3) Strengthen prevention and control measures The dialysis room strengthens prevention and control measures, and formulate prevention and control plans: isolation of the blood purification center area, closed management of the dialysis room, strict regulation on two closures, that is, closure of the front door of dialysis room and closure of the treatment area. Family members are not allowed to enter the room and for patients who cannot take care of themselves, all the care work is taken by the responsible nurses and caregivers. Dialysis patients get on and off the machine at staggered peak, and issue special dialysis certificate, vehicle license, fixed family member, fixed vehicle, fixed shift, fixed area, strict division, allocated machines and time interval to avoid personnel gathering. Ensure site cleaning before dialysis, strict closed-loop terminal disinfection, strict and correct hand washing, correct wearing of masks, and two-point one-line travel route. Set up pre-inspection team, the inspection content is dynamically linked to the epidemic situation, the inspection scope includes dialysis patients and their families, the order of investigation is: test temperature, health code display, nucleic acid test report within 7 days, and ask the patients about their travel trajectory during non-dialysis days. The body temperature of dialysis patients should be tested 4 times on the day of dialysis (before admission, before dialysis, 1 hour after the start of dialysis, and after dialysis). If the body temperature is ≥ 37.3 °C during dialysis and accompanied by symptoms such as cough, stop dialysis for epidemiological investigation. n the waiting area, use pictures and texts to make a one-meter interval sign, and paste cute little hedgehogs at the dividing points. The patient will feel love when seeing the little hedgehog, smile at each other, and tell jokes like don’t be stabbed by the little hedgehog. The humorous signs continuously remind patients not to gather or get together, and stick to the one-meter interval regulation during diagnosis and treatment. Earnestly implement a series of prevention and control measures, ensure the safety of diagnosis and treatment in details, leave no dead ends in the measures, and leave no hidden dangers in the investigation, promote continuous improvement of work, be strict on guard and ensure the safety of dialysis patients.
(4) Health education The outbreak of the novel coronavirus epidemic was sudden, fierce, and covering a wide range. It caused serious damage and had great impact on people, especially the vulnerable group of maintenance hemodialysis patients, who suffered even more in this epidemic. The staff in the department have further strengthened health education, strengthened publicity and guidance during the epidemic, and collected, edited, and pushed the knowledge of epidemic prevention and control as soon as possible, and guided patients to treat the epidemic correctly and rationally, without being nervous, afraid, not believing or spreading rumors, be confident, actively cooperate with epidemic prevention and control work, and actively create an atmosphere of positive energy.
(5) Nursing quality control During the novel coronavirus epidemic, the responsibilities of nursing staff have been highlighted. During the implementation of refined nursing interventions, nursing staff must strictly control the quality of nursing, and each nursing link should be intertwined to ensure the entire refined nursing process. At the same time, the nursing operation feedback information should be sorted out in the nursing process, and problems should be found and solved in time, so as to continuously improve the quality of nursing.
1.2.2.2 Nursing Intervention During Dialysis
(1) Strengthen education on epidemic prevention and control Educate patients about COVID-19 prevention knowledge, and correctly obtain information about the epidemic and related prevention and control and popular science knowledge, increase patients' awareness of COVID-19, and reduce their fear and strangeness, stabilize their psychological symptoms, and establish the confidence of patients to overcome the epidemic.
(2) Psychological intervention ①Mental health management Since the outbreak of COVID-19, some dialysis patients have been under great psychological pressure and have different degrees of negative emotions, such as worry, anxiety, depression, etc. [7]. The pressure comes from the lack of knowledge about COVID-19, the worry that dialysis treatment will be interrupted due to the epidemic, the worry that they themselves or their caregivers need to be isolated and feel helpless. Feeling dull and depressed, wearing a mask throughout the dialysis process, they worry about hypoglycemia, thirst and other discomforts. In order to effectively relieve the psychological pressure of dialysis patients and ensure the normal progress of hemodialysis treatment, nursing staff should pay attention to the patients’ mental state, spirit, and emotion, actively communicate with patients, and adopt coping strategies. Inform patients that they can bring some candies, straws, etc. for emergencies. Use professional psychological care channels for dialysis patients, establish a platform for talk and exchange, face-to-face, WeChat groups, and video guidance to relieve stress, shoot anti-epidemic videos in dialysis rooms, improve immunity through exercise, and enhance anti-epidemic friendship through interaction. The video content and forms are diverse, such as playing harmonica, poetry recitation, dancing with fans during dialysis, leg raising exercise during dialysis, waving to cheer for Wuhan, talent show and competition, patients encouraging each other and enhancing friendship. Appropriate exercise can reduce dialysis patients’ tension and anxiety, eliminate their life pressure and anxiety, make them feel more cared for, and at the same time enhance the nurse-patient relationship, improve the patients’ happiness index, and then improve their self-confidence, and face life positively, optimistically, and strongly, achieve the goal of happy dialysis, and ultimately improve patients’ compliance with dialysis treatment, and improve the quality of life of hemodialysis.② Emotional support Maintenance hemodialysis patients usually receive treatment three times a week, 4 hours each time. Most of the people they meet are medical staff and their surrounding wardmates. Nursing staff should adopt reasonable psychological intervention methods, actively care for patients and listen to patients' complaints, encourage patients to talk about their worries, ideas, treatment experience, and encourage patients to share self-dialysis experience. All these measures can effectively relieve the psychological pressure of patients Emotional fragility and depression of patients are one of the most common psychological problems of dialysis patients ༻8༽. Family members and dialysis partners are the main supporters of dialysis patients༻9,10༽. It can be effective to create a good doctor-patient and patient-patient harmonious relationship. Provide emotional support to enhance the patients’ ability to respond to COVID-19.
(3) Nursing operation norms Formulate corresponding nursing operation procedures and norms during the epidemic period, nurses must strictly follow the rules and procedures in their daily work, ensure that every nursing link meets the standard requirements, and strengthen monitoring of key nursing links. Due to the different degrees of psychological problems of dialysis patients, during the treatment process, patients will have negative psychological effects due to excessive stress, which will further affect their normal dialysis treatment. In order to effectively alleviate the psychological pressure of patients, nurses should "start from the heart". In the face of patients asking for help in pain and helplessness, nurses are no longer indifferent and cold, but enthusiastically help and patiently comfort every patient, with smile, love, enthusiasm, patience, sincerity, and responsibility. Nurses who are experienced and approved by patients provide treatment and care for patients, gain their trust and cooperation, create a good and harmonious nurse-patient relationship, and improve patient satisfaction, and thus win the honor for the department. After dialysis, the nursing staff assist or accompany patients with limited mobility to leave the dialysis room until they are handed over to the patients' family members to prevent adverse events.
1.2.2.3 Nursing Intervention After Dialysis
(1) Implement effective surface and air ventilation disinfection The dialysis room implements closed management, staggered on and off the machine, absolutely clears the field for dialysis. Between the two shifts, use 1000 mg/L chlorine disinfectant to wipe and disinfect the surface and ground, wipe and disinfect the high-frequency surface with 500 mg/L chlorine disinfectant[11], strengthen detailed control, strengthen high-frequency surface disinfection management of various surfaces, and leave no dead ends. Ensure the air quality of the hemodialysis center, fully ventilate the departments, strengthen the ventilation between the two shifts of dialysis, and open the purification system throughout the whole process[12], perform terminal disinfection and keep records, and strictly control the closed-loop disinfection.
(2) Strengthen prevention and control, prevent the spread of the epidemic, emphasize home self-management Improve prevention and control awareness, strengthen prevention and control during the epidemic. Dialysis patients go to the hospital for dialysis 3 times a week, 4 hours each time, other times are discharge time, so home self-management is particularly important. Fully implement the patient management system, as for health education, comprehensively analyze, evaluate, plan, implement, and follow-up to complete stratified, individualized and systematic health guidance [13], issue education brochures, strengthen the education of patients about prevention and treatment of COVID-19, actively cooperate with the government, neighborhoods, and communities to do a good job in prevention and control.① Monitor and control home self-management, inform patients to pay attention to personal hygiene, keep the room clean and tidy, open windows for ventilation, keep indoor air circulation, and instruct them to keep warm during ventilation in winter to avoid catching colds. Try to go out as little as possible, avoid contact with people with coughs and fevers, and avoid group activities such as parties to prevent the occurrence of cluster epidemics. If you must go out, you must wear a mask correctly and wash your hands before wearing a mask to maintain hand hygiene. Distinguish the front and back of the mask, keep the dark side facing out, the metal strip on top. The mask should cover the mouth, nose, and chin, and the metal strip should be close to the bridge of the nose, so that the mask fits closely with the face. The key is to cover the mouth and nose completely. Don't pull the mask to the jaw, neck, etc. for the convenience of speaking and eating, and don't hang the mask on the arm, which will contaminate the inner layer of the mask and lose its protective effect. The mask should be replaced in time after it gets wet or contaminated. When removing the mask, be sure not to touch the outside of the mask with your hands. Hold the elastic cords on both sides of the mask with your hands, remove the mask from both ears, and fold the outside of the mask in and the inside out, and throw it into the designated trash can. Wash your hands frequently at home, do not spit anywhere, pay attention to cough etiquette, cover your mouth and nose with a tissue or elbow sleeve when coughing or sneezing, and after coughing or sneezing, going home or receiving express delivery, be sure to use soap and running water or alcohol based hand sanitizer to wash your hands correctly and develop good living and hygiene habits.②The patient's body temperature and respiratory symptoms of novel coronavirus infection are monitored and reported in real time. ③During the epidemic prevention and control period, dialysis patients should avoid changing the location of dialysis: if they need to change, it is recommended that they check with the original dialysis center after the epidemic is controlled and then return. If the patient returns from other provinces, it is necessary to know whether there is contact history with confirmed or suspected infection cases, fever cases and their families, and there is no isolation at home. This should be handled in accordance with relevant isolation requirements, and appropriate protective measures should be taken. ④ Keep detailed records of fixed and hospitalized dialysis patients and their families' home addresses, travel tracking and registration, and detailed records of the contact history of confirmed or suspected infected persons, home isolation or fever patients, etc. The above related information shall not be concealed.
(3) Diet instruction Nutrients are the basic material for human growth and development. Good nutrition not only provides the human body with immunity against diseases including COVID-19, but also is the primary guarantee for promoting disease recovery. Therefore, dialysis patients should consume enough calories (30ཞ35 kcal/kg/ d) and high-quality protein (1.0ཞ1.2 g/kg/d at least 50% comes from high-quality animal protein), and vegetarian food is not recommended. Properly control water intake, especially in the hot summer season, more attention should be paid to water intake. In order to reduce thirst, patients should refrain from too salty diet and alcohol, avoid drinking strong tea and strong coffee. If you are really thirsty, you can rinse your mouth with water and spit it up. Remember that the weight gain between two dialysis sessions should not exceed 3–5% of your dry weight. Weight and blood pressure should be measured at fixed points every day. Accurately record and compare to assess whether the body's moisture is balanced, adhere to a low-salt, low-potassium and low-phosphorus diet, try not to eat raw food, separate cutting boards and tableware from raw and cooked food. Food should be washed and cooked. Wash hands before meals. During the epidemic, it is necessary to strengthen dietary hygiene and avoid eating overnight or unclean food, which may cause gastroenteritis and even peritonitis. Do not touch, buy and eat wild animals. Pay attention to the separation of raw and cooked food in the kitchen. Animal food should be cooked thoroughly. Family meals should be served individually or use public spoons and chopsticks to avoid mutual infection among family members.
(4) Proper body-building exercise to improve immunity Exercise has the effect of reducing negative emotions, enhancing physical fitness, and improving immunity. Exercise therapy uses the concept of sports medicine, based on the patient’s functional situation. Active and passive exercises help patients improve their overall function and local function [14, 15]. Refined nursing intervention combined with exercise therapy measures for hemodialysis patients can enhance the physical fitness of the patients through scientific and appropriate exercises. In turn, it helps the patient to develop a regular life routine, maintain the body's activity, produce effective stimulation to the nervous system, and make the patient's cerebral cortex in a relaxed state, thereby improving the patient's sleep quality. Effective stimulation makes the patient's cerebral cortex in a relaxed state, thereby improving the patient's sleep quality [16, 17], and also helping the patient to regulate biological rhythms and improve daytime sleepiness, and effectively promote the rationalization of body sleep and rest [18]. Thus reduce the adverse effects of hemodialysis and diseases, and improve the life function and quality of life of patients. Exercise therapy for hemodialysis patients can help patients form good exercise habits. Exercise can improve patients’ nerve excitability, increase body happiness, enhance confidence in disease treatment, relieve physical and mental stress, and relieve negative emotions such as depression and anxiety [19]. Nursing staff use their professional knowledge to help patients understand the benefits of exercise based on the patient’s own condition and physical fitness, assist patients in formulating scientific and reasonable exercise plans and personalized exercise programs, and gradually and slowly increase exercise time and intensity through a step-by-step method. With scientific nutrient supply, it helps patients maintain their energetic state, strengthen their physical functions, restore social functions, better integrate into society, increase participation in social activities, and improve patients' physical and mental health and quality of life [20].
(5) Improve spiritual realm and enrich cultural life During the epidemic, maintenance hemodialysis patients must love life more, care about current affairs, keep their mind open and at ease, overcome anxiety and fear, arrange life in a reasonable and orderly manner, and cultivate more hobbies, such as painting, calligraphy, embroidery, music, etc., let interests and hobbies arouse self-positive motivation, watch (listen to) more comedies, positive programs (books), watch (listen to) less or not (listen to) tragedy or negative programs (books) to enrich spiritual and cultural life.
(6) Popularize information technology and keep pace with the times In recent years, with the improvement of the medical security system and medical conditions, the average life expectancy of human beings has increased, and the number of elderly patients with chronic renal failure has continued to increase. Therefore, the number of elderly patients undergoing maintenance hemodialysis is also increasing [21]. People are gradually realizing that improving the quality of care for elderly patients with uremic maintenance hemodialysis is an important guarantee for improving the quality of life of elderly patients with uremic [22]. With the popularization of information technology, mobile phones have become an indispensable configuration in people’s daily lives, and people’s lifestyles have also changed. However, elderly maintenance hemodialysis patients lack the mastery of new technologies and skills. Most of the patients’ mobile phones are phones specially designed for the elderly, and some patients even do not have a mobile phone, and they don’t know anything about the Internet and WeChat. In order to enhance patients’ ability to cope with epidemics and emergencies, nursing staff strengthen communication with patients, carefully, patiently and meticulously guide them to learn to use online platforms, WeChat, QQ, online appointments, etc., and patients actively learn new technologies and master new skills. Some patients even bought a new smartphone for this purpose and actively cooperated with various measures, in order to overcome obstacles and respond effectively to epidemics or emergencies.
1.2.3 Statistical Methods
172 cases of maintenance hemodialysis patients in our hospital were selected. From February 1, 2020 (before intervention) to July 1, 2020 (after intervention), SCL-90 questionnaire survey method was used for retrospective analysis. Use the “questionnaire star” to scan the QR code with WeChat to fill in the questionnaire, which are distributed, explained and collected by a designated person. There were 172 questionnaires in total, 172 were returned, and the recovery rate was 100%.
Statistical analysis uses SPSS21 software, and measurement data analysis uses frequency, mean, standard deviation, and two-sample mean t test.
