Introduction

In China, the resuscitation room is used for cardiopulmonary resuscitation, endotracheal intubation, and advanced cardiac support. For example, patients who may require tracheal intubation, such as those with disorders of consciousness and inability to manage their airways, need to be admitted to the resuscitation room [1]. Most of the time, patients are admitted to the resuscitation room of the emergency department (ED) for active and life-saving treatment. However, for those with end-stage disease, no effective medical methods are available to save their lives [2]. Palliative care, which is intended to improve the quality of life of patients and their families’ facing problems associated with life-threatening illness, could be more effective than treatment in the resuscitation room [3]. Most Eds cannot provide a quiet and comfortable environment for patients.

Palliative care has been one of the most rapidly growing fields of health care in the past decade [4]. However, the knowledge of emergency patients and their families about palliative care in China is unclear. A previous study showed that patients with advanced cancer continued to present to the ED despite recommendations for early delivery of palliative care [5, 6]. In traditional Chinese culture, mentioning death can be considered taboo or even disrespectful, leading to a tendency to avoid conversations related to end-of-life decisions including palliative care [7]. In this study, we surveyed patients with end-stage disease and their families about their knowledge of palliative care and changes in choice before and after being surveyed.

Materials and methods

Study design and data sources

Patients who were admitted to the resuscitation room of the ED at Peking Union Medical College Hospital (PUMCH) from December 1, 2021, to June 1, 2022, and their families were enrolled in this study. As a referral center offering diagnostic and therapeutic care for complex and rare disorders in China, PUMCH is a tertiary care hospital in Beijing, and the patients come from all over the country. The resuscitation room of the ED has 21 beds that are closed off to visitors. The inclusion criteria for patients were as follows: suffering from an uncurable end-stage disease and a life expectancy of less than 6 months (determined by attending doctors from at least two or more departments) [8]; agreed participating in the study.

A separate online data collection questionnaire was used for the survey through a web platform (www.wjx.cn) that permits centralized data collection and limits duplicate mobile numbers (the English version of the questionnaire can be found in the Supplementary Material). The survey was a standard questionnaire that was constructed from themes based on a review of the literature and the study aim. The survey included two parts. Part 1 had 33 questions and consisted of four categories: category 1 included 5 questions that addressed demographic data (patient ID, sex, age, education level and religion); category 2 included 4 questions referring to the end-stage disease of the patient (type, treatment and end-stage care); category 3 included 7 questions that concentrated on the patient’s lifestyle and knowledge about the disease; and category 4 included 8 questions that concentrated on the patient’s family and financial support. The last category of seven questions referred to who made the decision and whether they needed the help of the hospice team. Part 2 evaluated health-related quality of life (HRQOL). HRQOL was measured using the Chinese version of the Medical Outcome Study 36-item Short Form Health Survey (MOS SF-36) [9, 10]. The MOS SF-36 consists of 36 items covering 8 areas, namely, physical function, physical roles, physical pain, overall health status, vitality, social function, emotional roles, and mental health.

This study was conducted among the patients and their families if the patients were awake and among the families only if the patients were in a coma. This study was approved by the Ethics Committee on Human Experimentation of Peking Union Medical College Hospital (reference number: JS-2898).

Statistics

All the statistical analyses were completed with Statistical Package for the Social Sciences (IBM SPSS Statistics for Windows, IBM Corp., Version 21.0, Armonk, NY). The normality of the data distribution was assessed using the Kolmogorov‒Smirnov test. A group t test was applied for normally distributed data, and the Mann‒Whitney U test was applied for nonnormally distributed data. The chi-square test was used for comparisons of two or more rates or components. Analyses are presented as two-sided comparisons. A P value less than 0.05 was considered to indicate statistical significance.

Results

1. General patient information

In total, 2095 patients were admitted to the resuscitation room of the ED during the study period. Eighty-two patients met the inclusion criteria and were enrolled in this study. The general information of the patients, including age, sex, education level, religious beliefs, family background, type of end-stage disease and perceptions of the disease status of the patients and families, is reported in Table 1.

A normal score lower than 50 indicated poorer HRQOL compared to that of the general population, and higher scores indicated a greater HRQOL. Sixty-six (80.49%) patients had a score lower than 50 in this study.

2. The influence of palliative care on the choice of place of death and rescue method at the end of life

Among the 82 patients included in this study, only 1 actively sought palliative care before admission. In addition, 9 patients received palliative care consultation after admission to the resuscitation room because they agreed with all rescue measures at admission, whereas the doctors believed these rescue measures were meaningless and would lead to additional pain and injury to the patients. The last chosen place of death was divided into two categories: the resuscitation room without company and other medical places accompanied by family. The last selected rescue methods were divided into three classes: no treatment, do not resuscitate (DNR) and agreement with all rescue measures, including cardiopulmonary resuscitation. For these patients, palliative care doctors further helped them and their families understand the condition of the disease, facilitate communication between them, and find ways to help them navigate the situation.

Patients who received palliative care before admission chose to be discharged home with pain relievers and do not resuscitate orders at admission. Among the 9 patients who received palliative care after being admitted to the resuscitation room, 4/9 (44.44%) were more likely to select a medical place of death accompanied by family at the end of life after receiving palliative care rather than the first choice of staying in the resuscitation room without any family before receiving palliative care. After receiving palliative care, 7 of the 9 patients who agreed with all the rescue measures initially opted not to be resuscitated at the end of life. The details are shown in Table 2.

3. Comparison of patients who ultimately chose different treatment schemes

As shown in Tables 3 and 10 (12.20%) patients chose to discontinue all treatment, 46 (56.10%) patients chose DNR, and 26 (31.71%) patients chose to undergo all rescue measures. There were no differences in age, sex, education level, religious beliefs or type of end-stage disease among the three groups (P > 0.05). Patients who agreed with all the rescue measures were more likely to be actively treated for major end-stage disease than were those who discontinued treatment in the treatment group (P = 0.005) or the DNR group (P = 0.012). Patients’ consciousness in the resuscitation room, awareness of the disease and duration of terminal disease were not significantly different among the groups (P > 0.05). Additionally, the presence or absence of a will and a strong desire for treatment were not significantly different (P > 0.05). In the treatment discontinuation group, the percentage (20%) of patients who had no children was the highest among the three groups, and 60% of the patients had 2 children. In the DNR group and all rescue measures group, most patients had 1 child (54.35% and 65.38%, respectively). HRQOL, which was assessed by the MOS SF-36 score, did not significantly differ among the three groups (P > 0.05).

4. The influence of patients’ knowledge of end-stage disease on the final choice of death place and rescue method

A total of 45 (54.89%) patients were completely aware of their disease, 13 (15.85%) patients were partially aware of their disease, 7 (8.54%) patients knew nothing about their disease, and the awareness of the disease was unclear in 17 (20.73%) patients. No differences were found in the last chosen place of death or in the last selected rescue method among the 4 groups (P = 0.314 and 0.456, respectively) or between patients who were aware of the disease (including all and partially informed patients, n = 58) and patients who were not aware of the disease (n = 7) (P = 0.131 and 0.297, respectively). The details are shown in Table 4.

Discussion

Our study showed that some patients (3.91%) with end-stage disease were admitted to the resuscitation room of the ED even though the frequency was not high. However, the frequency admittance to the resuscitation room may be greater in the whole country because PUMCH is the diagnosis and treatment center for complex, severe and rare diseases, and the proportion of patients with end-stage disease is relatively low. These data were consistent with previous data [11, 12]. Resuscitation rooms can cause fear, unease and loneliness in these patients rather than effective treatment. A previous study showed that ED-based end-of-life services did not alter the dying process [13]. Palliative care in the ED is crucial for effectively communicating with patients to determine their goals and provide medical care in line with their wishes [14]. Palliative care in the ED could help doctors provide essentially clear, empathetic communication and treatment of end-of-life symptoms [14]. A survey showed that the preferences for receiving palliative care and dying at home were greater than those for receiving actual care and highlighted the service gaps for better end-of-life care [15].

Only 1 (1.22%) patient in this study actively sought palliative care before admission. Patients’ and families’ knowledge about palliative care was lacking. Education about palliative care for patients and their families may help to solve this problem [16]. Doctors and social workers from our palliative care department help patients and their families have a sufficient understanding of the condition of the disease, facilitate communication between them, help them understand each other’s true thoughts, and find ways to help them navigate the situation. Even though receiving palliative care was at the discretion of the attending physician in this study, 44.44% (4/9) and 77.78% (7/9) of patients opted for a medical place of death accompanied by family and DNR, respectively, at the end of life after receiving palliative care. These findings showed that palliative care could help patients and families handle these situations in a more thoughtful manner.

To investigate the influence factors of the choice of treatment schemes at the end of life, characteristics of the patients choosing different treatment were prepared. The actively treatment of the underlying disease was correlated with positive treatment. And the number of children seemed to have some effect on the choice. However, the patients’ knowledge of the disease showed no influence on the choice. In this study, there were 8.54% (7/82) patients know nothing about the end-stage disease even though they were dying. Whether they had a strong desire for learning about the disease was unknown. Also, in this study, HRQOL showed no statistical difference among the groups choosing different rescue methods. Whether knowing about the disease and HRQOL had impact on the last decision of patients on the rescue method deserves more study.

However, the knowledge about the disease and HRQOL has an impact on the final decision of patients regarding the rescue method deserves additional study.

This study has several limitations. First, this was a single-center study, and national data could not be obtained. Second, the palliative care received by most of the patients in this study was at the discretion of the attending physician, and there was bias in terms of this judgment. Third, because of the critical conditions of the patients, many of the surveys were completed by family members, which may have affected the accuracy of the results of the assessment of patients’ subjective feelings. Finally, all patients in this study who asked to receive palliative care were included; however, the true proportion of patients willing to receive palliative care could not be confirmed.

Conclusions

For patients with end-stage disease admitted to the resuscitation room of the ED, knowledge of palliative care was lacking. Palliative care could help end-stage patients avoid the damage caused by pointless and invasive resuscitation and die peacefully.
