Spinal Cord Injury in Middle-aged and Older Adults Who Had Undergone Active Rehabilitation Treatment at a Remote Hospital: A Case Series.

Background: Middle-aged and older individuals with spinal cord injury (SCI) often require long-term care even after receiving rehabilitation treatment, making it difficult for them to return home. We retrospectively investigated our active rehabilitation treatment for patients with SCI. Case: Included in this case series were ten patients with SCI who were admitted to our general hospital (located in the southern part of Wakayama Prefecture) and who underwent active rehabilitation treatment. The participants were investigated retrospectively by access to electronic medical records. The Barthel index scores for discharged patients were determined at an outpatient clinic, and the community phase of rehabilitation management was recorded. The average age of the 10 patients was 67.4 ± 13.4 years, and the average period from onset to transfer to our hospital was 102.6 ± 69.9 days. The Barthel index scores significantly improved from 39.0 ± 30.9 at admission to 65.0 ± 28.2 at discharge (P<0.05). Among the seven patients who were discharged to their homes, six had cervical SCI. Some patients with American Spinal Injury Association impairment scale grades A and B at admission could be discharged home, and their Barthel index scores were maintained after discharge. Discussion: : Even in a remote rural hospital, the activities of daily living of patients with SCI improved, and seven of the ten patients were discharged home. The activities of daily living of the discharged patients were maintained. To achieve these results, active rehabilitation treatment conducted by rehabilitation specialists is important. 2022 The Japanese Association of Rehabilitation Medicine.

INTRODUCTION

Japan is a super-aged society, with 28.4% of the population aged ≥65 years. The percentage of older people is expected to exceed 30% in 2025 and 39.9% in 2060.[1],[2]) In recent years, the number of spinal cord injuries (SCIs) caused by falls in middle-aged and older people has increased in Japan. The age-specific morbidity rate of SCI has changed from the conventional bimodal nature of young and older people to a monomodal distribution around middle-aged people.[3],[4],[5]) Because the rate of cervical SCI is higher in middle-aged and older people,[4],[5]) and some older people have multiple disabilities,[6]) rehabilitation treatment is sometimes difficult. As a result, the physical function and activities of daily living (ADL) of such patients often do not improve significantly.[7]) Therefore, in urban areas, middle-aged and older people with SCI are generally treated at convalescent rehabilitation hospitals after acute treatment and after treatment in a hospital specializing in SCI.[8]) There are two hospitals that specialize in SCI in Hokkaido and Fukuoka in Japan; moreover, there is a large regional disparity in the number of beds available in convalescent hospitals. Tokyo has the highest number of beds, followed by Osaka and Fukuoka.[9]) However, if there is a delay after the onset of injury, treatment is often more difficult[10]); indeed, some patients are still physically disabled after rehabilitation treatment. These patients often require nursing care and it is, therefore, difficult to discharge them.[11],[12]) Providing sufficient care for older people is a social problem in Japan, and the lack of support from the younger generation makes it more difficult for them to be discharged home.[13])

In Japan, the long-term care insurance system was established in 2000,[14],[15]) and the number of people requiring long-term care services in 2019 exceeded 6.8 million. Among these, 551,000 were undergoing outpatient rehabilitation, and 120,000 were undergoing home visit rehabilitation.[16]) In many cases, middle-aged and older people with SCI who have been discharged home continue to live at home while making use of social resources and services.

The town of Nachikatsuura is located 170 km south of Wakayama City and has a population of 14,607; 42.1% of the population are aged ≥60 years, and 35.7% of elderly people live alone. Furthermore, it includes several villages surrounded by mountains and the sea. It sometimes may take more than an hour by car to get to a location where a medical examination can be performed. Moreover, there are no hospitals specializing in spinal cord injury or convalescent rehabilitation hospitals nearby. Many local families consist only of older people, and receiving family support is often difficult for those requiring long-term care. Nachi-Katsuura Onsen Hospital is the general hospital in charge of the community’s medical care and has four full-time rehabilitation doctors. Furthermore, active rehabilitation treatment in the hospital is delivered by rehabilitation-related professionals with specialized knowledge and skills. We performed active rehabilitation treatment for 10 middle-aged and older patients with SCI who were transferred to our hospital. This study aimed to retrospectively investigate and report the results of inpatient treatment and activity after discharge using medical records and to determine the effects of active rehabilitation treatment by rehabilitation specialists on middle-aged and older adults.

CASE

Ten patients with SCI who were admitted to our hospital between April 2014 and March 2016 and who received active rehabilitation treatment were included in this case series. The study included serial cases; however, nine patients who underwent regenerative spinal cord treatment and one who died during hospitalization from unrelated complications were excluded. Patient data were obtained from the hospitalization ledger, and the following items were obtained from electronic medical records: the physical function/Barthel index (BI) score at admission, length of hospital stay, rate of discharge, physical function/BI score at discharge, BI score at the outpatient clinic (patient living at home), and continuation of rehabilitation after discharge.

The demographic characteristics of the patients are presented in Table 1. We included seven male and three female participants with an average age of 67.4 ± 13.4 years. The period (mean ± SD) from SCI to transfer to our hospital was 102.6 ± 69.9 days. Seven patients had cervical SCI and three had thoracic SCI. The causes of the SCI were trauma in eight patients and disease in two patients. The AIS grades were A in two patients, B in two patients, C in two patients, and D in four patients. On admission, two patients had a tracheal tube, four patients had a urinary catheter, and one patient had a pressure ulcer.

This study was approved by the Nachi-Katsuura Onsen Hospital Ethics Committee (#R3-2). This research was explained to the patients, and written informed consent was obtained from all individual participants who were included in the study.

Rehabilitation Program

Rehabilitation doctors reassessed the cause of the SCI and its initial treatment and daily examined the level and degree of SCI. Furthermore, complications and comorbidities were confirmed. In addition to daily medical examinations, blood tests and imaging tests such as spinal magnetic resonance imaging; cervical, chest, and abdominal X-ray examinations; and cystography were performed as appropriate. Respiratory management; nutrition therapy; drug treatment for pain, spasticity, and dysuria; and pressure ulcer treatment were performed daily.

Individual physical therapy (maximum 3 h/day, 5 days/week), endurance training (Borg scale 13–15, 30–40 min/day), and muscle strengthening training (Borg scale 13–15, 40–50 min/day) were provided to all the patients, and transfer training (Borg scale 12–13, 30–40 min/day) and walking training (Borg scale 13–15, 50–60 min/day) were provided depending on the patient’s needs. For individual occupational therapy (maximum 2 h/day, 5 days/week), endurance training (Borg scale 13–15, 20–30 min/day) and muscle strengthening training (Borg scale 13–15, 20–30 min/day) were provided to all the patients. Furthermore, with emphasis on items with low BI scores, ADL/instrumental ADL training for returning home, such as floor movement training, feeding training, toileting training (e.g., movement and suppository insertion), and wheelchair transfer training, was provided depending on the patient. Physical function and ADL were measured and recorded by physiotherapists and occupational therapists at admission and discharge. For patients returning home, nurses and caregivers shared information with the therapists and conducted ADL training (60–80 min/day), such as feeding training, self-urinary catheterization guidance, bathing training, and dressing training, in the ward.

Rehabilitation treatment was performed daily during hospitalization for a maximum of 4–5 h per day. Individual training for up to 3 h was supervised by a therapist, and the remaining time was used for training under the guidance and supervision of doctors and nurses or for self-training such as stretching, push-up practice, and wheelchair maneuvering. In addition, rehabilitation staff and medical social workers visited the homes of patients about to be discharged and provided consultations on family guidance and housing modifications (Figs. 1 and 2).

Statistical Analysis

The Mann–Whitney test was performed to determine the differences in BI scores between admission and discharge, between admission and the outpatient clinic (i.e., the patient is living at home), and between discharge and the outpatient clinic (patient living at home). Data analysis was conducted using JMP Pro version 14.1 (SAS Institute Japan, Tokyo, Japan), and P<0.05 was considered statistically significant.

Findings

All the patients were admitted to the general ward, and seven were later transferred to the long-term medical care ward during hospitalization. After a patient moved to the long-term medical care ward, the doctor usually documented the reasons for continuing rehabilitation, indicating a possibility of improvement in ADL.

As a result of active rehabilitation treatment, the tracheal tube was removed in one of the two intubated patients. Moreover, self-urinary catheterization was established in all four catheterized patients, and the pressure ulcer was cured in the affected patient. Slight improvements in muscle strength were observed in all the patients, and no deterioration in paralysis was observed.

Table 2 shows the changes in BI scores between admission and discharge. The BI scores improved significantly from 39.0 ± 30.9 at admission to 65.0 ± 28.2 at discharge (P<0.05). Standing up from the floor, sitting for long periods, and self-transfer to a wheelchair were achieved by six of seven patients, four of six patients, and five of eight patients, respectively, who could not perform these activities before rehabilitation.

Seven patients were eventually discharged home, one was transferred to another hospital, and two were admitted to a facility. The average length of hospital stay was 259.8 ± 190.3 days. The levels of SCI at admission for the patients discharged home were C5 in two patients, C6 in one patient, C7 in three patients, and Th12 in one patient. Their AIS grades at admission were A, one patient; B, one patient; C, two patients; and D, three patients. Six of the seven patients had cervical SCI, and even some patients with AIS grades A and B at admission were discharged to home.

On 880.6 ± 400.5 days after discharge, five of the seven patients who were discharged home had undergone continued rehabilitation covered by long-term care insurance. The other two patients continued self-training and their BI scores were maintained after discharge (Fig. 3).

DISCUSSION

In this study, we report the results of active rehabilitation treatment and management in patients with SCI at a remote general hospital. The background of the patients with SCI at our hospital was similar to that of SCI patients in a national survey.[3],[4],[5]) However, the elapsed time from SCI to transfer to our hospital was long, making treatment difficult in many cases. Because our hospital is located in a medically depopulated area in the southern part of Wakayama Prefecture and no convalescent rehabilitation hospital is available in this area, many patients were transferred from an acute care hospital after long-term treatment. In Japan, a comprehensive community care system is being promoted, but in depopulated areas, medical and long-term care resources are scarce, and regional disparities exist in medical and long-term care services.[17]) Providing unique treatment and long-term care services that take advantage of the characteristics of the region within the scope of medical and long-term care policy is necessary for our hospital. Therefore, we aimed to increase the number of rehabilitation doctors, deepen multidisciplinary cooperation, and support regional medical care.

In this study, the results were favorable even though our facility is in a remote rural area in Japan. In urban areas in Japan, Yokoyama et al. reported that 17 patients with traumatic SCIs with paraplegia (mean age, 57.2 ± 10.0 years), for whom admission was delayed for 68.1 ± 32.9 days after injury, received inpatient rehabilitation treatment for 2 h/day, 5 days/week, for 115.6 ± 35.8 days at a hospital specializing in SCI, and the Functional Independence Measure (FIM) score improved from 74.1 ± 14.0 at admission to 107.2 ± 11.1 at discharge.[18]) Furthermore, Tanaka et al. reported that 154 patients with cervical SCI (mean age, 67.1 ± 12.7 years) whose admission was delayed for 49.1 (34.0–60.0) days after injury received inpatient rehabilitation treatment for 3 h/day for 119.7 (71.3–146.5) days in a convalescent rehabilitation hospital in Japan; their FIM score had improved by 23.0 (6.5–34.0) points at discharge from 58.0 (38.0–73.8) at admission.[19]) In a Canadian study, the effects of rehabilitation on middle-aged and older patients with quadriplegia (mean age, 50 ± 17 years) and paraplegia (mean age, 48 ± 18 years) resulting from subacute cervical SCI and SCI were investigated. The quadriplegia patients underwent 53 (44–62) min of physiotherapy and 44 (26–54) min of occupational therapy for 110 ± 51 days, whereas the paraplegia patients underwent 54 (45–59) min of physiotherapy and 34 (12–48) min of occupational therapy for 85 ± 38 days at a SCI rehabilitation hospital in an urban area. As a result, the SCIM III scores in patients with paraplegia and quadriplegia, respectively, improved from 50.7±17.0 to 66.6±17.1 points and from 32.7±23.8 to 52.3±27.8 points.[20]) In Italy, rehabilitation treatment for subacute SCI in middle-aged and elderly patients significantly improved the BI at discharge compared to admission.[21]) As mentioned previously, our facility has four full-time rehabilitation doctors, and regular training is organized for therapists, nurses, and caregivers. Rehabilitation doctors routinely perform appropriate disease and risk management. At our hospital, under the consultation of a rehabilitation doctor and in addition to active exercise therapy by therapists, intensive training was conducted to improve BI items with low scores. The nurses and caregivers who were responsible for maintaining physical function and improving ADL actively participated. However, the number of rehabilitation doctors in Japan is insufficient. Most of these doctors are available only in acute and convalescent hospitals in urban areas; consequently, the uneven distribution of doctors is a problem.[22]) The availability of four rehabilitation doctors in a remote general hospital is rare. However, rehabilitation doctors are needed in local hospitals not only to treat diseases and injuries but also to improve ADL, which can lead to satisfactory results as shown in the current study.

In this study, the BI score was maintained after discharge. Because our hospital is a local hospital, we work closely with local family doctors and care managers whose important roles are funded by long-term care insurance. Therefore, the medical care information of the patients can be sufficiently transmitted to the staff funded by long-term care insurance, thereby assuring a smooth transition from rehabilitation covered by medical insurance to rehabilitation covered by long-term care insurance. After discharge, patients are regularly followed up by a rehabilitation doctor for the evaluation of the SCI and ADL. Therefore, maintenance of the BI was achieved by instructing the patients and caregivers about changes in the ADL and training methods at the time of outpatient re-examination. In Japan, collaboration between medical care staff and long-term care staff is a topic of interest in the field of rehabilitation medicine.[23]) In particular, the training programs and evaluation methods used by the rehabilitation staff funded by medical insurance are sometimes not completely communicated to the rehabilitation staff funded by long-term care insurance. In addition, for rehabilitation covered by long-term care insurance, methods consistent with rehabilitation covered by medical insurance have not been established, and scientific rehabilitation programs and evaluations are scarce. In general, the ADL of older people with SCI who are discharged usually deteriorate. This leads to complications and an increase in the level of care required, thereby shortening the patient’s lifespan.[24]) However, good cooperation at our hospital was promoted by taking advantage of the characteristics of the small catchment area, and this led to the maintenance of ADL in discharged SCI patients.

This study has several limitations. First, although the functional differentiation of medical institutions is progressing in Japan,[25],[26]) when the participants were admitted, all were treated in the general ward. If hospitalization was prolonged for some patients, they were transferred to the long-term medical care ward. In this study, long-term, high-frequency, high-intensity rehabilitation treatment was performed, but the therapist calculated the minimum required set. The remaining time was used for self-training or training by a nurse under the supervision of a rehabilitation doctor. Recently, the long-term medical care ward in our hospital was adapted to become a ward for patients with disabilities.[27]) Improving ADL in older people with SCI may take a long time. In contrast to general and convalescent wards, no restrictions on the length of hospital stay are placed on wards for patients with disabilities. In addition to improving the ADL, preparations for home life, such as providing family guidance, home visit nursing, and service adjustment (including home visit rehabilitation before discharge), can be arranged. Second, during rehabilitation management funded by long-term care insurance, performing rehabilitation treatment equivalent to that covered by medical insurance is institutionally difficult.[15]) However, active self-training was combined to maintain activity in patients. Third, the BI was used as an evaluation outcome measure of activities in this study. The FIM is often used in convalescent rehabilitation hospitals, but the BI is often used in the community phase.[19],[28]) In the current study, consistent evaluations of changes in activities from hospitalization to the patient living at home were possible using the BI.

In the future, we believe that further improvements in physical function and ADL can be obtained by further collaboration with the regional acute-phase hospitals and by shortening the period from onset to transfer. Furthermore, increasing the number of rehabilitation doctors is necessary, which may be facilitated by actively accepting visits by medical students and residents and advocating for the necessity of rehabilitation medicine. Moreover, regular education of rehabilitation-related staff and increasing the number of specialists with knowledge and skills with regard to the treatment of people with SCI are warranted. Finally, we should deepen the collaboration between medical care staff and long-term care staff, promote the transmission of information to patients, and promote shared rehabilitation management and evaluation methods for people with SCI.

In conclusion, the ADL of the 10 SCI patients who received active rehabilitation treatment improved, and the majority of the patients were discharged home, including middle-aged and older patients with SCI who had been injured for a long time. Furthermore, the ADL of patients with SCI who returned home were maintained. To achieve these results, it is important that patients receive active rehabilitation treatments by rehabilitation-related professionals with specialized knowledge and skills and management by rehabilitation doctors.
