Box 9235 Centurion 0046 South Africa. E­mail: rhenn@worldonline.co.za AbSTrAcT: in order to overcome activity limitations, prevent secondary complications and early death and achieve community integration compre- hensive rehabilitation post spinal cord injury (SCi), is essential. The aim of the study was to evaluate outcomes of patients with complete paraplegia who received rehabilitation at a private rehabilitation hospital. A quantitative, descriptive methodology was implemented. All patients with complete, traumatic, thoracic spinal cord injuries, admitted to the study hospital in the study period, were consecutively sampled. Thirty five patients were identified of whom16 adhered to the inclusion criteria. The Functional independence measure (Fim) and needs Assessment Checklist (nAC) were used as measuring instruments. The mean length of stay was 95 days. discharge Fim motor scores ranged from 72 to 83 with a mean of 79.3. The mean gain in Fim motor score was 55 and varied from 45 to 61. discharge nAC scores ranged from 264 to 340 with a mean of 300 out of a possible 347. A correlation between length of stay and discharge Fim scores (p = 0.05) were found. Both nAC and Fim scores indicated high levels of physical independence. According to nAC scores patients were educated on the prevention of secondary complications and received psychological counselling. discharge planning and community integration scored lower with means of 80% and 61% respectively. Community based completion of rehabilitation programmes, the incorporation of the nAC, or another participation outcome measure and implemen- tation of on-going programme monitoring and assessment strategies is recommended.

Rehabilitation for SCI individuals is highly specialised and traditionally occurs in institutions such as tertiary hospitals and rehabilitation centers (Schönherr et al 1999). The Consortium for Spinal Cord Medicine (1999), have published clinical guidelines re expected functional outcomes following trau­ matic spinal cord injury. Functional recovery can be measured by various out­ come measures including the Modified Bartel Index (MBI), the Quadriplegia index of function (QIF), the Functional Independence Measure (FIM) and the Spinal cord independence measure (SCOM) (Anderson et al, 2008) to name but a few. The above measures are objec­ tive tools that do not take into considera­ tion the patient’s opinion and needs. In addition they measure activity and do not include participation measures such as community integration and employ­ ment. However, it is clear from the International Classification of Function, INTRODUCTION Spinal Cord Injury (SCI) is a relatively uncommon yet devastating cause of dis­ ability (McKinley et al, 2007). Persons with spinal cord lesions are confronted with motor and sensory impairments as well as bladder and bowel dysfunction, which cause activity limitations and can have a severe impact on participation in life (McKinley et al, 2007). The nature and severity of activity limitations and participation restrictions are dependent on the severity and site of the lesion as well as the person’s social roles and con­ textual factors (McKinley et al, 2007). Numerous secondary complications may arise from SCI (Eng & Miller 2008). Thus comprehensive rehabilitation post spinal cord injury is crucial to prevent complications such as pressure ulcers and early mortality (Krause et al, 2008), to improve function and to assist with community reintegration and economic self sufficiency (Schönherr et al 1999). Disability and Health’s (ICF) definition that rehabilitation should encompass all measures necessary to maximize physi­ cal and psychological health, including social, economic and vocational aspects and that the person and his/her opinion plays an important role in determin­ ing outcomes (WHO 2000). Therefore subjective tools that take the patient’s opinion into account and participation measures must be included in outcome measurement studies and practices. The Rehabilitation Hospital, where this study was conducted, is a 120 bed private rehabilitation hospital in 16 SA JournAl of PhySiotherAPy 2012 Vol 68 no 1 Gauteng, where a rehabilitation program for patients with paraplegia, amongst others, is being offered by an interdisci­ plinary rehabilitation team. The overall aim of the rehabilitation program for patients with paraplegia at the rehabilita­ tion hospital is to ensure that the patient achieves physical independence using a wheelchair and to prepare the patient for integration back into the commu­ nity. The outcomes of the program have not been assessed since its inception in 1999. It was therefore unknown whether the program achieved its aims as stated above. Thus the current study evolved to assess the outcomes of patients with complete paraplegia who received rehabilitation at this hospital. Specific objectives included determining whether there were any relationship between length of stay and FIM and/or Needs Assessment Checklist (NAC) scores, how functional outcomes of patients according to FIM and NAC scores com­ pared to expected outcomes according to the Clinical Practice Guidelines (CPG) of the Consortium for Spinal Cord Medicine (1999) and assess community integration outcomes of patients accord­ ing to NAC scores. METHODOLOGY The study was registered with the University of Stellenbosch’s Committee for Human Research. Permission to perform the study and access patient records was obtained from the direc­ tor of the hospital. Participation in the study was voluntary and every study participant signed a consent form before participating in the study. Information disclosed by participants was kept con­ fidential. A quantitative, descriptive metho­ dology was implemented. The study population consisted of a consecutive sample of all patients admitted to the study hospital with a complete, trau­ matic, thoracic spinal cord injury, classi­ fied as ASIA A, by a the medical doctor at the study hospital, during the period; 1 April 2004 to 31 December 2007. A total of 35 patients were identified. Of these, 19 had to be excluded according to the study’s exclusion criteria; eight suffered from systemic conditions such as cardiovascular disease, which might includes using it for research purposes. The primary author of this article com­ pleted all the FIM assessments. She is internationally certified to use the FIM and has been using it regularly for eight years. In accordance with FIM guidelines admission scores were deter­ mined within three days after admission (Anderson et al 2008). Discharge FIM scores were determined by the same person one day before discharge. Both assessments were completed in the spinal ward of the hospital using the patient’s hospital bed and the ward’s bathroom. The curtains were drawn around the bed to ensure patient privacy and to prevent interruptions. The Needs Assessment Checklist it is a valid, reliable and sensitive tool that can assist with focussing rehabilitation programs on individual patients needs (Berry & Kennedy 2002). The check­ list covers nine domains: activities of daily living, skin management, blad­ der manage ment, bowel management, mobility, equipment, community prepa­ ration, discharge coordination and psy­ chological issues (Kennedy et al 2003). impact negatively on outcomes, nine were discharged before completion of rehabilitation in the opinion of the rehabilitation team and two died during rehabilitation, thus their individual out­ comes could not be assessed. Thus 16 patients participated in the study. The FIM and Needs Assessment Checklist (NAC) were used as measur­ ing instruments in the study. The FIM, a valid, reliable and sensitive instrument, was chosen primarily since it is the only outcome measure currently in use in the study setting. It measures the functional independence of a person on 18 activi­ ties that are each scored on a seven point scale (1 – 7) (Masedo, et al 2004). For the purposes of this study only the motor subscale of the FIM were used as sug­ gested by Anderson et al (2008): “if the Fim were to be used in clinical research settings to assess motor function, it may be more useful to only use the motor subscale portion of the Fim and disre- gard the cognitive subscale portion”. The study hospital is subscribed to use the FIM, a copyrighted instrument, and pays a monthly license fee, which Table 1: Demographic profile and information on injury Gender distribution Male 13 Female 3 Age distribution 21 – 20 7 31 – 40 7 41 – 50 2 educational level Grade 8 5 Grade 10 5 Tertiary education 6 Pre injury employment status Employed 15 Student 1 Transport Own 11 Public 5 Level of injury T4 1 T5 3 T6 2 T8 2 T11 5 T12 3 Cause of injury Motor vehicle accident 8 Violence 3 Industrial 4 Fall 1 17 SA JournAl of PhySiotherAPy 2012 Vol 68 no 1 It is completed by the patient, who rates his/her level of independence for each item on a scale from 0 to 3. No distinc­ tion is made between verbal and phy sical independence (Kennedy & Hamilton 1999). The NAC was chosen as an addi­ tional measuring instrument in the study since it provides the patients’ views of their functional ability and, in addition, assess issues related to the prevention of secondary complications, employment and community integration. Participants completed the NAC on the day before discharge at a time con­ venient to them in a private, quiet room. The checklist and the scoring were explained individually to each partici­ pant by the primary author and they were allowed to fill it in with no time con­ straints. Explanations and translations were provided to non­English speaking participants through an interpreter. Not translating this instrument created bias as explanations from the translator might have changed between participants. The lack of an admission NAC score was a further shortcoming in the study. All data was entered onto an excel spreadsheet and analysed with the assistance of a statistician using STATIS TICA Version 7. Specific tests (Spearman; Kruskall Wallis) were done to determine statistical significance of selected findings such as the relation­ ship between length of stay (LOS) and mean FIM admission and FIM and NAC discharge scores. A p value of < 0.05 was deemed statistically significant. RESULTS The demographic details of the study population are presented in table 1. The mean age of the study population was 32 years with ages ranging from 21 to 47. All sixteen patients were from urban areas and resided in houses. All parti­ cipants, except one who was a student, were employed and six had higher education. Motor vehicle accidents were the most common cause of injury. The combined LOS in acute and rehabilitation hospitals ranges from 83 to 152 days with a mean of 113 days. The mean length of stay (LOS) in the rehabilitation hospital was 95 days (SD = 20.83) with the length of stay ranging Diagnosis; LS Means Current effect: F(4, 10)=1.0673, p=0.42 Kruskal-Wallis p=0.38 Effective hypothesis decomposition Vertical bars denote 0.95 confidence intervals T 5 Paraplegia T 6 Parapegia T 8 Paraplegia T 11 Paraplegia T 12 Paraplegia Diagnosis 40 50 60 70 80 90 100 110 120 130 140 150 L O S Figure 2: level of lesion compared to length of stay from 51 days to 124 days. Ten patients stayed longer than the expected 84 days as set out by the rehabilitation program. There was no correlation between length of stay and NAC (p = 0.26; r = – 0.3) scores. According to figure 1 there was some correlation between length of stay and discharge FIM scores (p = 0.05, r = ­0.51). No statistically significant relationship could be found between LOS and the level of the lesion (p = 0.38). However, clinically mean LOS decreased by 30 days from 110 days for T5 lesions to 80 days for T12 lesions as indicated in figure 2. The admission FIM motor score ranged from 23 to 27 with a mean of 24.3 (SD = 1.19) out of a possible 91. In the domains of bladder and bowel as well as transfers and mobility, areas where a patient with paraplegia has to acquire new skills, all patients scored the low­ est possible score, i.e. one out of seven. Neither gender (p = 0.35) nor level of injury (p = 0.39) or cause of injury (p = 0.83) had any significant impact on FIM admission scores. Discharge FIM scores ranged from 72 to 83 out of a possible 91. The mean FIM discharge motor score was 79.3 (SD = 2.89). Most categories in the FIM showed gains in the mean score with Data 1 in DAT A 20081126.stw 9v*16c LOS:Disc FIM: r = -0.4232, p = 0.1024 Spearman r = -0.51 p=0.05 40 50 60 70 80 90 100 110 120 130 LOS 72 74 76 78 80 82 84 D isc F IM Figure 1: length of stay compared to discharge FiM score 18 SA JournAl of PhySiotherAPy 2012 Vol 68 no 1 the biggest improvements in the bladder and bowel and, the transfers and mobi­ lity categories.

No significance could be found between gender (p = 0.19), level of lesion (p = 0.67) and cause of injury (p = 0.95) and NAC scores. Findings from the FIM and NAC were translated into percentages in order to compare them to each other and the Consortium for Spinal Cord Medicine (1999) guidelines. The FIM and NAC comparative findings are presented in Table 2. With regards to self­care scores include the motor FIM scores in the Self­care category i.e. eating, grooming, bathing, toileting and dressing upper and lower body. NAC scores include scores in the Activities of Daily Living category i.e. food management, facial hygiene, personal hygiene and dressing upper and lower body. The mean per­ centage for the FIM self­care score was 95. 5 %, with a median of 97% while the NAC mean percentage was 99% and the median 100%. It is evident that the patients’ perception of their indepen­ dence in self­care is better than what was reflected by objective FIM scores. The lower mean score in bladder and bowel management achieved in the FIM can possibly be explained by the fact that patients with paraplegia are taught to empty their bladders with the aid of a catheter in the rehabilitation unit where the study was performed. Thus no paraplegic could score the maximum of seven for this category even if com­ pletely independent in this activity. For the mobility FIM scores, the patients were observed while doing trans­ fers in hospital to their beds, the toilet, a bath and a car. They were also observed Diagnosis; LS Means Current effect: F(4, 10)=.48925, p=0.74 Kruskal-Wallis p=0.65 Effective hypothesis decomposition Vertical bars denote 0.95 confidence intervals T 5 Paraplegia T 6 Parapegia T 8 Paraplegia T 11 Paraplegia T 12 Paraplegia Diagnosis 70 72 74 76 78 80 82 84 86 88 D isc F IM Figure 3: FIM discharge scores compared to level of injury 19 SA JournAl of PhySiotherAPy 2012 Vol 68 no 1 while propelling a wheelchair on a level surface for 50m. On comparing the FIM and NAC scores it is again noted that the NAC mean (95) is higher than that of the FIM (76). No patient was scored more than 80% independent in transfers and mobility, while no patient scored him/ herself lower than 80% independent in the tasks that were part of this category. The expected FIM outcome accord­ ing to the Consortium for Spinal Cord Medicine (1999) is 86­100% for self­ care activities, bowel management and transfers, while it is 86% for bladder management and wheelchair mobility. Thus the results of this study correlated well with the expected outcomes for self­care, bladder and bowel manage­ ment. The lower mobility FIM scores (66 to 80%) could be because the patients were scored on four different transfers while the CPG only refers to bed­wheel­ chair transfer. Scores from additional NAC catego­ ries as summarised in Table 3 indicated that prevention of secondary complica­ tions had been addressed to the patients’ satisfaction by the rehabilitation pro­ gramme. Scores for knowledge on and mainte­ nance of wheelchair and equipment, were good but a low of 33 indicates that this is an area that requires attention. Similarly scores for psychological counselling indicates that the programme fared well in this respect. The two outcomes that raised concern about the program were discharge planning and commu­ nity integration. Community integration includes social activities, employment, community preparation and, driving and transport issues. On closer scrutiny it was found that the questions about employment were scored the lowest. Seven patients reported that adaptations were necessary for them to return to work and that at the time of discharge no adaptations were made, three patients also reported that they had made no plans to return to work. No work visits were done by the rehabilitation team. The discharge planning category includes community issues, accommo­ dation and carer training. The questions focus on the patient’s preparation for dis­ charge, adaptations to their houses and on knowledge regarding where to find medical assistance in their communities. In this area twelve of the patients scored lower than 70% with six scoring below 50% and four above 80%. Six patients did not receive a home visit to assist them with the planning of home adapta­ tions and 11 (69%) did not know where to access specialised medical support in the community after discharge. DISCUSSION While the demographic details of the study population such as gender ratio (4:1) and mean age at the time of the injury (32) correlates with literature (Blackwell et al, 2001; Wyndaele & Wyndaele 2006; McKinley et al 2007; Wirth et al 2010), the authors want to caution readers to carefully consider the demographic details and study­setting for similarities and differences before extrapolating results since the study population consisted of a small, homog­ enous group, with no systemic diseases, from a privileged setting who could afford medical insurance and private rehabilitation. The patient’s physical outcomes were good. Both objective scores from the FIM as well as subjective NAC scores indicated positive outcomes in this area and it was confirmed by the favour­ able comparison of FIM scores with the expected scores from the CPG (1999). The length of stay for paraplegics undergoing rehabilitation at the study hospital is set at 84 days. When one reviewed the LOS figures from Schön­ herr et al 1999 (mean = 157 days) and Wirth et al (2010) (mean = 250 days) it is not surprising that ten participants in the current study stayed longer than the pre­ ordained 84 days. The need for a reha­ bilitation period longer than 84 days, whether in patient or community based is supported by a study which measured physical progress post SCI, with the SCIM (Wirth et al, 2010). Wirth et al (2010) found a mean improvement of 39 points after 4 months (120 days) and a further mean improvement of 11 points after three more months (90 days or 210 days in total). When one takes into consideration that nine patients were discharged home early, in the opinion of treating profes­ sionals, from the programme under study, because of a lack of funds, it appears that length of stay at the study hospital is to a large extent determined by the insurance companies’ payment policies rather than by the patients’ needs. This indicates a need to educate insurers about the reha­ bilitation needs of SCI patients’ and the need to explore the option of com­ munity based rehabilitation programs if the cost of hospitalisation proves to be an inhibiting factor for optimal rehabi­ litation. Another possible solution could be that the rehabilitation program for SCI patients be changed, in accordance with The National Rehabilitation Policy of South Africa (Department of Health, 2000), to incorporate an institution based phase and a community based phase to ensure patients receive the necessary length of rehabilitation required. Patients showed marked functional improvement as measured by the FIM and NAC. Thus the rehabilitation pro­ gram is effective in terms of addressing patient’s needs for physical indepen­ dence. While these findings reflected well on the rehabilitation program, one must raise the question of why the FIM is used as the only outcomes measure in the programme since it is according to a literature review on the subject “not a suitable outcome tool” to “detect small but functionally significant amounts of change in the SCI population” (Anderson et al, 2008 p.141). The challenges with regard to responsiveness experienced when using the FIM in the SCI popula­ tion was illustrated in this study again. The NAC score range in bladder and bowel management (51 to 100) was much wider than that of the FIM (79 to 86) as well as a ceiling effect and underscoring in sphincter management and mobility since the use of assistive devices makes it impossible to have a perfect score on the FIM. However, the patients saw themselves as independ­ ent in these areas as the perfect NAC scores indicated. Thus even as an activ­ ity measure the FIM showed shortcom­ ings for this type of population and the SCIM III (Anderson et al, 2008) would be a more suitable alternative, while a participation measure such as the NAC or participation subset of the International Classification of Function (ICF) (WHO, 2000) should also be implemented. 20 SA JournAl of PhySiotherAPy 2012 Vol 68 no 1 To properly asses the outcomes of a rehabilitation program one must include participation measures to assess; com­ munity integration, employment and preparation for these during rehabilita­ tion. The majority of the patients in this study were of an age to return to mean­ ingful employment after rehabilitation. However, the NAC results indicated that according to patient perception the program experienced challenges in this regard, for example no work visits were undertaken by the rehabilitation team in the current study. This lack in SCI rehabilitation services was also iden­ tified in other studies as presented by Ottomanelli et al (2009) in a review on the literature of employment of persons with spinal cord injuries. It is essential that the rehabilitation programme focus on assisting persons with a disability to return to employment. The rehabilitation programme must be extended to provide support on issues like reasonable accommodation, especially since South African legisla­ tion supports this process through the Employment Equity Act (RSA, 1998), the Code of Good Practice (RSA, 2002) and the Technical Assistance Guidelines (Department of labour, 2002). The study participants had some advantages over the general population for to returning to employment such as being of a young age, having a higher qualification in 38% of cases and having been employed in administrative work before the injury (Ottomanelli et al 2009). Higher levels of education provide a person with increased choice in type of employ­ ment, often require less change in type of employment and usually indicate individuals with more autonomy and motivation (Ottomanelli et al 2009). One of the main barriers to employment after spinal cord injury is dependency on pub­ lic transport (Ottomanelli et al, 2009). Therefore, the five participants in the current study who are dependent on pub­ lic transport might have more pro blems than their counterparts to secure and maintain employment, especially due to the lack of accessible public transport in SA (Howell et al 2006). Another area which showed poorer outcomes was the referral of patients to community health care services. Since the study hospital does not fol­ low up patients, it is therefore, essential that patients are referred to community based service providers knowledge­ able about the condition of SCI and its management, especially the prevention and management of secondary compli­ cations. Persons with SCI are prone to a myriad of secondary complications such as, bladder infections, pressure sores, respiratory infections and depression that can lead to high levels or morbidity and early mortality (Krause et al, 2008). Education about the maintenance of adequate health should be an essen­ tial part of a rehabilitation program (Ottomanelli et al, 2009). This was addressed in part by the current pro­ gramme, since the NAC scores indicated high levels of education on preven­ tion of complications, but the program failed to supply patients with knowledge about where to go for treatment of these problems should they occur. CONCLUSION The overall aim of the rehabilitation program at the study hospital is to pre­ pare the patient for functional indepen­ dence in a wheelchair and to successfully integrate back to his/her community. This study found that the patient was functionally independent in physical activities by the time of discharge, but that the rehabilitation program was not equally effective in the preparation for integration into the community. While there were some attempts to prepare the patient for participation and social roles, the bulk of the program is activity focused, and did not assist the patients after discharge from the hospital with the actual community reintegration process. RECOMMENDATIONS A rehabilitation program which com­ bines a shorter in­patient phase to address issues like bladder and bowel management, and basic self­care, with a community based phase that com­ pletes these aspects of rehabilitation and also addresses home, community and work integration is recommended. The development of such programs will need careful consideration, planning and research. The South African Spinal Cord Association could play an inva­ luable role with regard to developing and initiating such programs. With regards to outcome measures used the results of the study had shown a need for an activity measure more specifically focused on individuals with spinal cord injuries such as the SCIM III or the NAC. The NAC has been found to be a suitable instrument to measure both physical independence and the extent to which patient needs had been met in terms of preparation for participation in social roles. Therefore it is recom­ mended that the NAC is introduced as a measuring instrument into the spinal cord injury rehabilitation program at the study hospital. There is a need to complete the NAC during the rehabili­ tation process and on discharge. Since the rehabilitation period is set arbitra­ rily at twelve weeks and the issues that were found lacking in the rehabilitation program according to the NAC focused mainly on community preparation and discharge coordination, areas that are traditionally addressed during the more advanced stages of rehabilitation, it is recommended that the NAC is ini­ tially completed after the first month of rehabilitation. This information can then be used to set specific patient­centred goals with regards to community inte­ gration for the final two months of reha­ bilitation. It is further recommended that per­ formance measurement becomes an inte­ gral part of the rehabilitation program at the study hospital and is performed on a regular basis. This will provide manage­ ment with feedback on programme effi­ ciency, quality and effectiveness that can be implemented to continuously improve on the programme.
