BMC Geriatrics volume 23, Article number: 606 (2023) Cite this article

Abstract

Background

The quality of life (QoL) of elderly patients with bone trauma is significantly decreased and is affected by many complex factors. This study aims to conduct a half-year follow-up survey to clarify QoL and its influencing factors in elderly patients with bone trauma in order to provide targeted care measures for elderly patients with bone trauma.

Methods

This was a longitudinal observational study. We used the 36-Item Short Form Health Survey (SF-36) to investigate and evaluate the QoL of 100 patients with bone trauma at the time of hospital discharge and 1 month, 3 months, and 6 months after discharge. Our previous study confirmed that the SF-36 had higher reliability and validity for evaluating the QoL of elderly patients with bone trauma. At the same time, we also investigated the age, gender, location of bone trauma, and destination after discharge of those patients. Those factors that might affect the QoL of elderly patients with bone trauma were identified by univariate and multivariate analyses.

Results

The total physiological function, role-physical, bodily pain, vitality, social functioning, role-emotional, and mental health scores of elderly patients with bone trauma gradually increased from the time of discharge to 1 month, 3 months, and 6 months after discharge, and there were significant differences (p < 0.001). However, there was no significant difference in the general health score in the different periods (P = 0.095). The total QoL scores also significantly differed (F = 118.61, P < 0.001) at the time of discharge (335.252 ± 127.572) and 1 month (285.149 ± 112.827), 3 months (479.344 ± 153.663), and 6 months after discharge (544.396 ± 166.536). The univariate analysis results showed that the location of bone trauma (P < 0.005) and the destination after discharge (P < 0.001) were the main factors affecting QoL in different periods. The results of the multivariate analysis showed that the location of bone trauma was an important factor affecting QoL (P < 0.005 in different periods). Whether to undergo surgery was a factor affecting the patients’ long-term QoL (P < 0.005 at 6 months after discharge).

Conclusions

Although the QoL of elderly patients with bone trauma gradually improves after injury, their recovery time is long, and the influencing factors are complex. Follow-up services should continue for at least six months for these patients, and comprehensive treatment and long-term rehabilitation services should be provided.

Peer Review reports

Background

With the rapid development of related industries such as manufacturing and transportation, the occurrence of industrial accidents, traffic accidents, natural disasters, etc., has increased, and the number of patients with bone trauma has also increased significantly [1, 2]. Bone trauma can be divided into different types according to the injury site, including limb, clavicle, and lumbar fractures [3]. Elderly people have decreased bone density, mineral loss, and decreased muscle protection, so they are more prone to fractures; due to improvements in the treatment of chronic diseases, an increasing number of elderly people have a more active lifestyle, making the elderly population more vulnerable to injury [4,5,6]. Coupled with increased life expectancy, bone trauma is causing more elderly people to present to emergency departments [7]. It has been found that more than 50% of elderly trauma patients have single or multiple fractures [8].

Elderly patients with bone trauma often experience pain, swelling, limb deformities, dysfunction, abnormal daily activities, etc., which seriously affect their physical and mental health. Bone trauma causes malnutrition, dysfunction, and even disability, which seriously reduce quality of life (QoL) [9]. QoL is affected by many factors. A three-year survey of 5057 elderly patients with low-trauma fractures in Canada showed that despite a rebound in health-related quality of life (HRQoL) one month after the fracture, HRQoL will permanently decrease in the long term. Mobility had the greatest impact on HRQoL changes [10].

However, at present, China lacks specific tools to evaluate the QoL of elderly patients with bone trauma, and there is also a lack of in-depth and long-term follow-up research on the QoL of elderly patients with bone trauma. At the same time, there is a lack of comprehensive research on the factors influencing QoL in elderly patients with bone trauma. Thus, the QoL of elderly patients after bone trauma and its influencing factors in China are worth exploring and analyzing. In this research, we intended to analyze the QoL of elderly patients with bone trauma and its influencing factors through a six-month follow-up survey in a large general hospital in western China. This study could provide a reference for improving the QoL of elderly patients with bone trauma.

Methods

Study design and sampling

This study was a longitudinal observational study and obtained ethical approval. We adopted a convenient sampling method and selected elderly patients with bone trauma who were hospitalized in the trauma medical center of a comprehensive tertiary hospital in Chengdu between November 2021 and June 2022. The inclusion criteria were as follows: patients aged ≥ 60 years old who were admitted to the hospital due to bone trauma, conscious and expressive patients who had never used anti-anxiety or anti-depressant drugs, and patients who were informed and willing to cooperate with the investigator. The exclusion criteria were patients with mental symptoms and communication difficulties and discharged patients who were neglected by family members. The number of samples should be at least 5–10 times the number of variables. Through the previous literature review, approximately 10 related factors affecting QoL were identified. Considering a loss rate of 10%-15%, the sample size should be 58–118 people. Finally, the sample size of the follow-up survey was determined to be 100 elderly patients with bone trauma. The average age of the participants was 72.30 ± 9.702 years, and the average length of hospitalization was 10.82 ± 8.278 days. Five of the 100 patients died on the 4th, 6th, 14th, 107th and 184th days after injury.

Survey tool

At present, there is no specific survey tool for evaluating the QoL of elderly patients with bone trauma. Our research team reviewed the literature and used the 36-Item Short Form Health Survey (SF-36), the 12-Item Short Form Health Survey (SF-12) and the EuroQol Five Dimensions Questionnaire (EQ-5D) to evaluate and compare the QoL of 157 elderly patients with bone trauma. The Cronbach coefficients of the SF-36, SF-12 and EQ-5D were 0.877, 0.701, and 0.393, respectively, and the construct validity (the degree to which a test measures the theoretical structure and traits to be measured) Kaiser‒Meyer‒Olkin (KMO) values were 0.762, 0.697, and 0.612, respectively. Therefore, the SF-36 had higher reliability and validity in evaluating elderly patients with bone trauma and was used as the follow-up survey tool for this research [11]. This tool includes the following 8 dimensions, which belong to two categories (physical health and mental health): physiological function (PF), role-physical (RP), bodily pain (BP), general health (GH), vitality (VT), social functioning (SF), role-emotional (RE) and mental health (MH). The higher the SF-36 score is, the better a patient’s physical function and mental state [12, 13].

At the same time, we also collected basic information about the patients, such as age, gender, location of bone trauma, education level, monthly income, whether they underwent surgery, and destination after discharge. Therefore, we can analyze the factors that affect the QoL of patients. These data were obtained by surveying patients during their admission period.

Data collection

The QoL of the included elderly bone trauma patients was investigated and evaluated at the time of discharge and 1 month, 3 months, and 6 months after discharge. The survey content included the general information of the patients (age, gender, surgical status, education level, occupation, etc.) and their SF-36 scores. The investigators were clinical nurses who had been uniformly trained. The training included an explanation of the SF-36 scale, how to use SF-36 to evaluate elderly bone trauma patients, telephone follow-up methods, and communication skills between nurses and patients. The QoL assessment was completed in person when the patients were discharged from the hospital, and their QoL was assessed by telephone follow-up at 1, 3, and 6 months after discharge.

Statistical analysis

After the follow-up data were collected and sorted, SPSS 26.0 statistical software was used for analysis and processing. The QoL score of the patient was expressed as the mean ± standard deviation. The patients’ QoL scores in different periods were compared by one-way repeated measures analysis of variance. Univariate and multivariate analyses were conducted for the relevant factors influencing QoL in different periods. The log rank method was adopted for univariate analysis, and multiple linear regression analysis was adopted for multivariate analysis. P < 0.05 indicated that the difference was statistically significant.

Results

QoL scores of the patients in different periods

For the 8 dimensions included in the SF-36, the scores of physiological function, role-physical, bodily pain, vitality, social functioning, role-emotional and mental health were significantly different at the time of discharge and 1 month, 3 months, and 6 months after discharge (P < 0.001) (Fig. 1). However, there was no significant difference in general health score among the different periods (P = 0.095) (Fig. 1). The total QoL scores of the SF-36 were also significantly different (F = 118.61, P < 0.001) at the time of discharge (335.252 ± 127.572) and 1 month (285.149 ± 112.827), 3 months (479.344 ± 153.663), and 6 months after discharge (544.396 ± 166.536). In addition, the patients’ QoL scores decreased 1 month after discharge and then gradually increased.

Analysis of factors influencing patients' QoL

Log rank test results for univariate analysis showed that the patients’ QoL was mainly related to the location of bone trauma and the destination after discharge (Table 1).

Multivariate analysis showed that the main factors affecting the patients’ QoL at discharge were the location of bone trauma and the destination after discharge. The main factors influencing QoL at 1 month after discharge were marital status and destination after discharge. The main factors influencing QoL at 3 months after discharge were sex and destination after discharge, and the main factors influencing QoL at 6 months after discharge were surgical status, age, education level, monthly income, and destination after discharge (Table 2).

Discussion

Elderly patients are more likely to be injured due to minor accidents than younger people, and they experience greater difficulty compensating for injuries caused by trauma [14]. Because of multimorbidity, elderly patients are more likely to use multiple drugs to treat chronic diseases, some of which may reduce their response to traumatic physiological stress, thereby increasing the risk of complications [15]. As a result, older trauma patients also have a higher risk of severe disability and death [16]. The incidence of bone trauma is high in elderly patients.

The results of this study showed that among the eight dimensions of the SF-36, only the general health score showed no difference, while the scores of the other seven dimensions gradually increased. The mental health and role-emotional scores were higher, while the role-physical and physiological function scores were lower. The results are consistent with those of Chen Yun’s [17] survey in 2016, which evaluated the QoL of 486 elderly patients with hip fracture. That study showed that the QoL of elderly patients with hip fractures was at a moderate to low level three months after surgery. Due to influencing factors (such as poor physical function, the coexistence of multiple diseases, pain, and long-term bed rest), elderly patients with bone trauma had a long recovery time, a low physiological function score, poor recovery of limb function, and a poor ability to take care of themselves. As time went on, the patients’ scores on all QoL dimensions increased in our study. This result is consistent with the survey on HRQoL of patients after total hip arthroplasty, which was conducted by Shi HY in 2009. That study showed a significant improvement in the SF-36 score of the patients 6 months after discharge [18].

Our research also showed that the patients' total QoL score decreased 1 month after discharge and then gradually increased. This may be related to the patients’ health conditions at discharge, the type of care after discharge, family support and other factors. The previous relevant research of our team showed that when surgical patients were discharged after surgery, their postoperative recovery quality scores were lower than those before surgery. Those patients still have a high requirement for care [19]. Bone trauma patients often need professional rehabilitation treatment after discharge. However, most patients in this study chose to undergo rehabilitation at home. Therefore, they lack professional rehabilitation guidance. It has a great impact on the recovery of physiological functions, which results in low QoL scores.

Many factors affect the QoL scores of elderly patients with bone trauma. The main factors include the location of the trauma and the destination after discharge. Regarding the location of bone trauma, the patients with upper limb fractures had the highest QoL scores, while those with pelvic fractures had the lowest scores. Patients with pelvic fractures often require more complicated treatment, longer recovery time, and need to remain in bed for a long time. This will have a great impact on their QoL [20]. A study conducted by Tarride J E [10] in Canada in 2016 also found that the HRQoL of elderly patients with pelvic fractures did not return to the level before fracture, even at 36 months after the injury. Therefore, continuous care and long-term rehabilitation treatment after discharge are essential for elderly patients with pelvic fractures.

Regarding the destination after discharge, the QoL of patients who continue rehabilitation at home after discharge is higher, while at subordinate hospitals or nursing homes, it is lower. Patients transferred to subordinate hospitals after discharge often suffer more serious injuries, have worse body functions, and need long-term rehabilitation treatment. Therefore, these patients have lower QoL. Due to China's medical system and care methods, as well as the lack of professional rehabilitation institutions and the imperfect medical insurance reimbursement mechanism, most patients choose to continue treatment at home after discharge [21]. Early geriatric services, specialized trauma care, and geriatric trauma consultation services can help reduce the chances of staying in long-term care facilities after discharge [22, 23]. Therefore, when elderly patients with bone trauma return home, medical staff in hospitals and communities should provide professional care, rehabilitation guidance, and social support resources. It can significantly improve the QoL of patients.

In addition, surgical status is also one of the factors affecting the long-term (6 months after injury) QoL of elderly patients with bone trauma. Elderly patients who choose to undergo surgery after injury have higher QoL scores. Some scholars believe that the timing of surgery is not related to postoperative complications or mortality [24]. However, some studies have shown that prompt surgery after injury can quickly correct fracture displacement, rebuild joint function, improve the fracture healing rate, effectively relieve pain, shorten bed rest time, and improve QoL [25]. In this study, 80% of the patients underwent surgical treatment, and no deaths occurred. A study in the UK in 2006 showed that in elderly patients with hip fractures, if surgery is delayed for more than 4 days, the mortality rate will significantly increase [26]. Another study in the United States in 2016 suggested that markers of resuscitation (such as pH and base excess) may dictate the appropriate timing of surgery [27]. However, whether surgery should be performed for elderly patients with bone trauma still requires comprehensive evaluation of the patient's condition and health status, the medical team's treatment capabilities and other factors.

Due to time and researcher limitations, in this study, only a six-month follow-up survey of elderly patients with bone trauma was conducted, and only 100 hospitalized patients were included. A larger sample size and longer investigation period may lead to more diverse results on the long-term QoL outcomes of elderly bone trauma patients. Meanwhile, because of admitted diseases, the bone trauma included in this research was mainly musculoskeletal injuries of the pelvis and extremities. There was no indication of thoracic or cervical spine trauma. The QoL of patients may vary depending on the location of the bone trauma. In the future, we would like to carry out relevant research in multiple hospitals, including more elderly patients with bone trauma and focusing on elderly patients with cervical and thoracic trauma. We would like to conduct a longer follow-up survey. Perhaps we can obtain more interesting results.

Conclusion

This study aimed to explore long-term QoL and its influencing factors in elderly patients with bone trauma. We found that the QoL of elderly patients with bone trauma was low at discharge, and the main factors influencing QoL were the location of bone trauma, the destination after discharge and surgical status. This study has certain limitations, such as insufficient follow-up time and small sample size, which may affect the analysis of long-term QoL for those patients. Our research still reveals the changes in the QoL of patients after bone trauma and the important influencing factors. At the same time, our findings indicate that hospital staff and community and nursing home staff should provide continuous care and rehabilitation services for elderly patients with bone trauma after discharge. Follow-up services should continue for at least six months for patients who undergo home rehabilitation after discharge. Simultaneously, informing their rehabilitation status and providing guidance, comprehensive treatment, and rehabilitation services can improve their QoL. Meanwhile, longer follow-up periods, larger sample sizes, and more comprehensive bone trauma locations can be embraced in future studies.
