COPD is a progressive chronic lung disease with irreversible airflow constraints, and the course of the disease is long and progressive. At present, the incidence of COPD is increasing, with the global prevalence of 11.7%  , high disability rate   and high genetic   have been proven. In addition, the co-existence of COPD in other chronic diseases increases the risk of death from related diseases  . COPD requires long-term medication, although drugs can optimize airway function and alleviate symptoms, they cannot eliminate the psychological effects, which include depression and anxiety, social isolation, loss of independence and the damage of self-esteem, etc. At present, at least half of COPD patients have not acquired any diagnosis before serious damage occurs  , leading to the not optimistic current situation about self-management of COPD patients. Currently, related theories which used in patients with COPD disease management mainly include Bandura Learning theory  , Self-efficacy theory  , Cross-theoretical model   and so on. Mostly the quality of patients’ life can be improved by health education, but the intervention measures only remain at the education level. The latest edition of the guidelines for the diagnosis and treatment of COPD points out that the treatment of stable COPD patients mainly includes drug treatment and non-drug treatment, among which non-drug treatment includes health education and self-management, exercise, lung rehabilitation and so on [Figure 1]. However, it is clear that the traditional health education cannot change patients’ behaviors, or even achieve the goal of motivating patients. At the same time, it is pointed out that education and self-management should exist simultaneously. Empowerment theory emphasizes the co-creation of knowledge, not just the passive transfer of knowledge, and stresses the participation process of patients  , which makes up the deficiency of current research. At present, the research of the empowerment theory in COPD patients is far behind that of other chronic diseases   . However, good self-management after empowerment has been regarded as the key to prevent disease progression  . Moreover, the application of the empowerment

theory in stroke, hypertension and diabetes has also proved that empowerment can improve patients’ ability of disease management and quality of life. In this paper, we expound the application progress of the empowerment theory in patients with COPD, in order to provide reference for the long-term study of COPD.
2. Definition of Empowerment
Empowerment originated in the last century. It is divided into social empowerment and psychological empowerment, especially emphasis on self-awareness and individual potential  . In clinical nursing practice, it is often referred to as “empowerment” or “authorization”. Under the great influence of Carl Rogers’ humanism, most of the nursing practices focusing on psychological empowerment. At present, the concept has been blurred and extended due to the free use  , Fotokian, Shahboulaghi, Fallahi-Khoshknab, and Pourhabib  think empowerment is a dynamic and creative process for patients, the series of adaptations made by the patients after they are empowered and they have a high degree of autonomy, but it also emphasizes dependence on the help of others, which is an interactive concept.
3. Application Status of Empowerment Tools at Home and Abroad
The application of appropriate empowerment measurement tools can directly evaluate the effect of patients’ empowerment. So necessary empowerment tools are also indispensable in the process of patients’ empowerment. Sun and Jiang  described in detail 18 empowerment measurement tools at home and abroad, which were applied to different disease. At present, empowerment measurement tools are widely used in foreign countries, but not all of them have been applied in China due to the differences of regions and research objects. In China, The Diabetes Empowerment Scale-short Form (DES)   . The Elders Health Empowerment Scale (HES)  and The Chinese version of The Empowerment Scale for patients with chronic diseases  have been well developed with well reliability and validity. In addition, Zhang and Li  in China also developed a questionnaire for the measurement of empowerment in patients with stroke, which was proved to have stable internal consistency. However, the empowerment related measurement tools for patients with COPD mainly include Patient Activation Measure (PAM), and there are 13 clauses of them, Cronbach’s alpha was 0.88, which has not been translated into Chinese, and there is no systematic empowerment measurement tool of COPD in China.
4. Application and Effect of Empowerment Theory in COPD Patients
In terms of the literature, although they all have their own priorities, they are interrelated. And the ways and contents of empowerment are different, which involve patients in many aspects of disease management [Table 1], such as smoking
Table 1. Application and effect of empowerment theory in COPD patients.
cessation, exercise, breathing strategies, nursing in acute exacerbation period and psychological stress management. Medicine is changing from traditional medical practice to a positive and personalized discipline. Traditional medical and health care models are not suitable for chronic diseases  . This is because traditional health care models tend to address acute events with a disease-oriented approach, ignoring the patient’s dominant position. Individualized medicine emphasizes the main status of patients  , which is suitable for the management of chronic diseases. The theory of empowerment following the trend of personalized medicine, because the focus of empowerment theory is to empower patients and let them in an active position.
4.1. Etiological Prevention
The department of health clearly pointed out that quitting smoking could prevent and avoid exacerbation of COPD  . Kaptein, Tiemensma, Broadbent, Asijee, and Voorhaar  tested the feasibility of the innovative approach by asking people with COPD to draw pictures, the picture asked the patient to draw their cognitive lungs, accompanied by a short disease perception questionnaire (Brief-Illness Perception Questionnaire, B-IPQ) to assess patients’ awareness of their disease, eighty-seven of them completed the drawing and believed that COPD was related to smoking and truly accepted to quit smoking. Similarly, Wenters and Bygholm  browsed COPD patients’ communication posts on the site, finding smoking and exercise were the most talked about topics among the 398 patients, who said it was important to change habits and lifestyles and believed that quitting smoking and exercising could prolong their lives.
4.2. Sports Guidance
Maintaining a certain level of physical activity can be a challenge for patients with COPD, who may experience dyspnea during exercise and may bring about threats and embarrassment  . Therefore most COPD patients cannot coping with the limited activity level when the disease is aggravated. While physical activity is considered as an important target for COPD treatment. Dobbels et al.  conducted 3 consecutive qualitative studies on 116 patients, a conceptual framework of physical activity is established, in which patients understand the importance of physical activity and learn to recognize adverse symptoms that occur during activity. Desveaux et al.  conducted a 6 months study of “minimally supervised exercise intervention” in a community, in which 12 patients received exercise intervention for half a year. Patients realized the importance of exercise plan which not only improved physical health, but also improved psychological mood, and Identified the obstacles to the rehabilitation.
4.3. Respiratory Exercise
For patients with COPD, respiratory exercise is an extremely important form of lung rehabilitation. Koldkjaer, Caroe, Lindgren, and Mathiesen  conducted respiratory counseling and training for patients with moderate and severe COPD, working out the specific needs of patients and greatly alleviating their anxiety caused by dyspnea. In China, Jiang  significantly improved patients’ lung function and self-efficacy through empowerment education training. Similarly, Zhang and Luo  also showed that the 6-month training of empowerment breathing also improved the self-efficacy of COPD patients. This demonstrates the relevant researchers proposed that drugs cannot solve the psychological problems of patients  .
4.4. Readmission Rates
Because the characteristic of relapse, so the study of the readmission rate of COPD patients has also been paid more attention. Collins worth et al.  assessed the feasibility of a long-term care education program for COPD and determined whether the program affected the readmission rate of patients. Although result proved the feasibility of the education program and improved patients’ knowledge, there was no significant statistical difference between the two groups in readmission rate. Lavesen, Ladelund, Frederiksen, Lindhardt, and Overgaard  conducted similar study, discussing whether discharged COPD patients can improve their awareness and reduce readmission rate through telephone follow-up. The result also showed that not reduce the patients with COPD readmission rate.
4.5. The Application of Telemedicine
At present, telemedicine is widely used for chronic diseases, but it is still a neglected field as an empowerment tool  . It is undeniable that telemedicine has shown great potential in increasing patients’ rights   .
Nissen and Lindhardt  conducted a six-month telemedicine intervention study, through the remote device to receive timely feedback about health of the patients. According to the feedback results, the necessary coping strategies were given to the patients. In the process, Patients gain a sense of control and security over their illness. Bond  also found similar results, some patients believed that they are involved in medical decisions, but some patients thought the use of the remote device to be a burden for them. This is understandable, because it can be difficult for COPD patients to detect and respond appropriately to worsening conditions. And that the details were worked out by the nurse and patient is still in a passive position, the hoped-for “participatory health” into a “medical paternalism”. Relevant studies  also prove this point, the researcher thought most of the current studies described relationship of empowerment between doctors and patients as “authorization” and “obedience”, ignoring the patient’s subject status in the process of empowering. Lilholt, Haesum, and Hejlesen  have also proved that telemedicine can improve ability of disease management, but the difference is that It’s a pure quantitative study. In China, relevant studies conducted by Luan  and Li  have also confirmed that telemedicine has great benefits in self-management and self-efficacy of COPD patients.
The effects of telemedicine devices are considerable. A common feature of these studies is that as patients spend more time using telemedicine devices, their disease management ability, quality of life and emotional improvement also increase. Rixon et al.  also demonstrated the viewpoint.
4.6. Website Communication
The development of the Internet has provided a new platform for empowerment. Through online conversations with 398 COPD patients, Wentzer and Bygholm  concluded that online support group was an important resource for empowerment, and developed corresponding coping strategies based on the most talked about topics (smoking cessation and rehabilitation courses).Lu and Zheng  developed a network platform for patient of COPD, although the purpose was to confirm whether the relevant volunteers were COPD patients, patients actively participated in this process during the collection of disease information and improved their disease management ability.
5. Factors Influencing the Empowerment of Patients with COPD
Although a lot of researches shown that empowerment can improve patientsability of disease management, not all patients respond to empowerment in this process  . In other words, the level of receive empowerment depends on their participation about health issues  . If only empowering rights of patients without evaluation, it may lead to the aggravation of the patient’s illness and even death  . Therefore, “patient activation” is also the focus of many researchers, most of whom measure the activation degree and ability of patients after empowerment through the PAM-13 scale.
Studies indicated that relevant factors mainly include psychological factors (such as not wanting to face the occurrence or aggravation of the disease), no experience in coping with the disease, and lack of external support, but external support is also proposed as a contributing factor    . Mullerova et al.  concluded that high expectations of disease, poor health, and low satisfaction with health care workers are also barriers. Stoilkova-Hartmann, Franssen, Augustin, Wouters, and Barnard  further refined the obstacles in the process of disease management, such as social support, environment and lifestyle in external factors, health belief and internal motivation in internal factors [Table 2]. The results of these studies suggest that the quality of life and self-management of disease in patients with COPD are dependent on the individual’s condition after empowerment.
From the above, empowerment theory is a process in which patients gain the ability to cope with diseases and improve their sense of self-efficacy and have necessary knowledge, skills and attitudes. In addition, the empowerment process emphasizes patient involvement. More and more attention has been paid to the application of empowerment theory in patients with COPD. In view of the current situation, the following outlook is proposed:
At present, the measurement tools for chronic diseases are diversified, and it’s applied to different specialist areas. Since most of them are introduced from foreign countries, we need to verify whether they are practical in application. PAM-13
Table 2. Influencing factors of COPD patient empowerment.
is widely used in foreign countries for COPD empowerment measurement tools, but it has not been sinicized at present, which is a direction of future research. In addition, in the process of using and developing the scale, the influencing factors of empowerment should be fully considered. A large number of studies are still needed to explore which factors can be corrected, and then improve patients’ ability to accept empowerment and enjoy a higher quality of life. In the study, we should pay attention to the heterogeneity of patient characteristics and formulate different intervention measures according to different characteristics.
Empowerment has a significant effect on the etiology prevention, exercise, breathing exercise, telemedicine and website communication about COPD patients. Considering the complexity, repetition, and progressiveness of COPD, empowerment had little effect on readmission rates, only shortened the readmission time. We need more comprehensive disease management programme to improve outcomes in the future. In order to adapt to the economic restructuring, chronic disease management is particularly important. But due to the heterogeneity of COPD, we must take into account the impact of a patient’s unique environment when caring for them. COPD patients still need regular outpatient follow-up in the stable stage of the disease, so as to detect the progress of the disease, but it also causes increased pressure on outpatient visits. As a new empowerment tool, telemedicine reduces the pressure on the number of patients in medical departments and optimizes the health resources, which is the trend of smart medical research and direction of future research. Besides, monitoring the use of telemedicine is extremely important, because we don’t just keep track of the data, we need to make professional judgments about the progress of the disease. The expertise of professionals is the lifeblood of remote device use, which cannot be ignored in future studies.
