Physical disability and its social and functional repercussions in patients with leprosy after discharge from multidrug therapy.
Leprosy is a chronic infectious disease that presents a spectrum of clinical manifestations defined by the patient's immune response. (1) It is characterised by the occurrence of mononeuritis multiplex, which may occur during one or many recurrent episodes of reactions of immunological origin that result in autonomic, sensory and motor neuropathy which become the main cause of physical disabilities. (2,3)
Physical disability is the most striking feature of leprosy, and continues to be a severe problem in public health programmes in endemic countries. The World Health Organization (WHO) defines the criteria for cure as regular administration of multidrug therapy (MDT) over 6 to 12 months. The number of patients handicapped during or after MDT has been an important public health problem, as leprosy is one of the most physically limiting diseases. (4)
In 2013, Brazil detected 31,044 new cases of leprosy. Of these, 27,364 cases were evaluated for disability, with 24.1% (6,607 cases) having Grade 1 and 7.2% (1,996 cases) having Grade 2 disability. Considering only the cases from that year, there are 8,603 cases of leprosy needing an integrated therapeutic approach, as well as requiring actions for the prevention of further disabilities, self-care and physical rehabilitation for those individuals. (5)
The deformities caused by leprosy can cause functional disability, as well as social discrimination and stigma, with severe psychological and social repercussions, that may lead to the formation of an environmental barrier for social participation. (6-9) Studies have highlighted the causal relationship between physical disability, restriction in social participation and functional limitation for leprosy patients after MDT discharge. (12)
Considering the disabling character and the stigma related to leprosy, it is necessary to develop an integrated approach to patients affected, regarding the bio-psychosocial aspects. Questions such as disability, limitation of activities and restriction of participation must be considered as fundamental and be evaluated during and, if possible, after the treatment. (12,13)
Regarding the elimination goal, as recognised by WHO and considering that the criteria of therapeutic discharge does not take into account the consequences already present or the ones that may yet develop after MDT discharge, referral centres for the prevention of physical disability such as the 'Hospital Universitario Clementino Fraga Filho (HUCFF)' from the Federal University of Rio de Janeiro (UFRJ) are essential. Those units should allow for the social and functional reintegration of people suffering from this disease. This hospital has developed, since 1998, the 'Project of Prevention and Physical and Surgical Rehabilitation in Leprosy,' involving professionals from Physiotherapy, Psychiatry, Orthopedics, Dermatology, Social Work, Occupational Therapy, Psychology and Neurology, as well as involving undergraduate and graduate students from the Federal University of Rio de Janeiro. The objectives of this study were to describe the clinical characteristics, functional and social limitations of patients referred to the HUCFF, over the period 1998 to 2013, due to physical complications and/or physical disability.
Material and Methods
The study was approved by the Committee of Ethics in Research from the Secretaria Municipal de Saudedo Rio de Janeiro, under record number 96/13. A cross-sectional descriptive study was developed in the HUCFF, a reference unit in the southeastern region of Brazil. A convenience sample of 182 leprosy patients was studied corresponding to the case load at the hospital.
Inclusion criteria were: patients with leprosy, both genders, and older than 12 years old. Exclusion criteria were patients with other peripheral nerve diseases and cognitive deficits. Physical disability was evaluated by the 'degree of physical disability' and measured by a simplified neurological evaluation, as recognised by the Ministry of Health. This tool evaluates eyes, hands and feet using a 3 point scale (0, 1 and 2).
The Participation Scale was used to measure the social participation, whose domains are part of the International Classification of Disability and Health (ICF). It is a validated questionnaire, with 18 items quantifying the restrictions to participation experienced by leprosy patients and other disabling diseases. The scores range from 0 to 90 points. The cutoff to establish the presence of social restriction is 12 points. The classification of social restriction considers 13-22 as light restriction, 23-32 moderate restriction, 33-52 large restriction and 53-90 extreme restriction. (9)
The SALSA Scale was also developed based on ICF. It aims to evaluate the extent of activity limitation, an important tool to know how disability affects the daily life of people affected. The result of this evaluation is a score ranging from 0 and 80. Lower scores indicate fewer difficulties when performing daily life activities, while higher scores indicate growing levels of limitation (without limitation until 24; light limitation 25 to 39; moderate limitation 40 to 49; severe limitation 50 to 59; very severe limitation 60 to 80). (14)
Data collection was performed at HUCCF or in the patient's home, by the main researcher. Patients were invited by telephone to go to HUCCF in order to perform the evaluation. The phone call was made three times, on different days and times. Patients without a telephone for contact in the medical records were visited by the main researcher at their homes.
Data analysis was conducted with SPSS software, version 20-0. Data were expressed in tables by frequency (n) and percentage (%) according to the groups. The associations were studied with bivariate analysis of odds ratio (OR), confidence intervals of 95% and statistical significance P < 0-05.
Variable degrees of physical disability was categorised as 'presence of disability' (corresponding to individuals who, at the moment of evaluation, had Grade 1 or 2 disability) and 'absence of physical disability' (individuals that had Grade 0 disability). The Participation Scale was categorised as 'presence of restriction' (individuals that had light, moderate, large and extreme scores) and 'absence of restriction' (individuals that had score without restriction). The SALSA Scale was categorised as 'without limitation' (corresponding to individuals that had no limitation in daily life activities) and 'with limitation' (corresponding to individuals that had light, moderate, severe or very severe limitations in daily life).
We also studied the association between: (i) physical disability as an outcome and the socio-demographic, clinical and social restriction variables; (ii) the association between social participation as an outcome and socio-demographic, clinical and physical disability variables and (iii) functional limitation as an outcome and socio-demographic, clinical, physical disability and social restriction variables. Aiming to identify socio-demographic and clinical variables associated with the degree of physical disability, the Participation Scale and the SALSA Scale were assessed in [chi square] tests.
Initially, a total of 182 cases were identified through the medical records; 136 patients (12 to 82 years old, average age of 44-6 [+ or -] 15.05 years old), with 41.9% (n = 57) females and 58.1% (n = 79) males were evaluated. Prior to the study there were 46 losses, including 23 addresses not found, 14 changes of address to other cities, seven deaths and two with an incomplete address in the medical records.
From the evaluated patients (n = 136), 86% had multibacillary and 14% (19) paucibacillary form. From those, at the moment of evaluation, 124 patients (91.2%) had some degree of disability (57.4% Grade 1 and 33.8% Grade 2), corticosteroid therapy (27.2%), and pain (56.5%). The characterisation of the population regarding the clinical profile is described in Table 1.
In Table 2, it is possible to observe the disability according to a stratified age group.
In this study, the 136 evaluated patients had impairment of 210 ulnar nerves (16.2% were unilateral and 69.1% bilateral); 209 median nerves (16-2% unilateral and 68.4% bilateral); 207 tibial nerves (15.4% unilateral and 684% bilateral); and 215 fibular nerves (19.9% unilateral and 69.1% bilateral).
Ninety-five neural decompression surgeries were performed in 47 patients. Of those, 24 patients had 30 ulnar nerves decompressed (20 unilateral and five bilateral); 11 had median nerves decompressed, all unilateral (four right and seven left); 30 had 33 tibial nerves decompressed (27 unilateral and three bilateral) and 19 patients had 21 fibular nerves decompressed (17 unilateral and two bilateral).
Forty-five reconstructive surgeries were performed on 30 patients, 14 corrections of claw hand (one right, five left, four bilateral); nine corrections of claws in the digits of the feet (four right, three left and one bilateral); 16 corrections of drop foot (10 right and six left) and six surgeries for plantar ulcers (four right and two left).
According to Table 3 there were no significant differences in the distribution of the physical disability variable according to gender or age.
According to Table 4, those experiencing pain were more likely to have limitation of activity.
According to Table 5 there were no significant differences in the Participation Scale results according to the socio-demographic and clinical variables.
Tables 6 and 7 present the frequency of scores of the SALSA and Participation Scales.
In Table 8 no statistical significance was observed regarding the presence or absence of physical deformity according to scores of SALSA and Participation Scales in the evaluated patients.
The goal of eliminating leprosy established by the WHO, reachable due to the drastic decrease in world prevalence during the last 30 years, is related to and warranted by the implementation of MDT. Moreover, it is important to study the frequency of physical disabilities in a reference hospital in the area of physical and surgical rehabilitation in an endemic country such as Brazil. In our study, 91.2% of patients had some degree of disability. From those, 33.8% were classified as Grade 2.
It is important to note that this study was conducted in a referral hospital, which receives patients who generally already have some disability. Thus a higher degree of nerve impairment, disability, activity limitation and participation restriction may be expected as compared with studies of unselected leprosy patients. In the study of Brandao, we see that only 31% of patients post-discharge of Brazil have disabilities, but in our study this rate is 91%, because of the specific nature of the demand for a referral hospital. (5) At the hospital, the patient is evaluated and, if the disability is reversible, he/she is forwarded to the physical therapy department, where pre-surgery preparation is carried out. If the disability is not reversible, the patient is referred for occupational therapy with the goal of adapting the daily routine, with or without the use of orthotic devices. These interventions should be considered when analysing the results, especially in comparison with other studies where the patient was not referred to physical rehabilitation or surgical intervention.
Leprosy may affect body image and self-esteem. The stigma that goes with this disease may result in restriction of social participation. (15,16) Because of that, individuals need professional, family and social support. (17)
A relevant question to be evaluated is the perspective of the patient regarding the disease, the treatment, the perception of the need for care and limitations imposed from a personal, social and working point of view. (18) After discharge, many patients still need assistance due to the complications of the disease. However, the patients have few options when looking for care in the health sector, resulting in pain and insecurity. (12,19) In order to address those concerns, the HUCFF offers a monthly self-care group, a weekly group of art therapy, individual work with physical therapists and dermatologists besides clinical sessions with the interdisciplinary team in which hands and foot surgeons participate. Thus, considering that around 30-50% of patients with leprosy develop reactions and therefore are at risk of complications, it is crucial that there is a systematic work-group allowing patients affected by leprosy to be reintegrated with their social and work environment. (1,10,12,13)
The literature highlighted evidence of associations between age, gender, clinical form, number of nerves affected in the beginning of treatment, degree of disability at the moment of diagnosis and bacteriological load as predictive factors for physical disabilities. (20,21) In 2007, after multivariate analysis, the study by Ranque et al. concluded that the only statistically significant risk factors for the occurrence of sequelae were sensorial or motor deficit and age, both for multibacillary as well as for paucibacillary patients. (22)
According to Sarkar, multibacillary patients have more disabilities than paucibacillary patients (31.6% vs 10%), in line with our data. (23) This finding was corroborated by other studies. (24,25)
This study revealed damage to more than one nerve in 96.3% of patients. The incidence of single neuritis in this population was 2.2%, smaller when compared to the findings of Penna reporting 11.8%. (26)
Our data revealed that there was no association between the SALSA score and the presence of deformity. (1) We believe that a possible reason could be the fact that patients already adapted to the deformity and did not see it as an obstacle for performing their daily activities normally. From the clinical point of view, it is expected that the elderly patient presents a lesser degree of activity, which may be another reason for the lower impact of disability as a cause for the limitation of activity. Other studies also found this lack of an association. (13,27) Regarding pain, our data revealed that patients with some complaints had twice the risk of activity limitation. It is worth highlighting though that this study was not about pain. The SALSA and Participation scales are validated tools, based on ICF, which examine the subject according to the biopsychological and social model, enabling a wider perspective regarding assistance. (15) In our study, 52.2% of the sample had some degree of restriction regarding social participation, higher than the findings of Castro, Singh et al. and Nardi, that had respectively 24.9%, 46% and 35% individuals with social restriction. (10,12,28) The finding in this study of 75% limitation of activity was higher than the one found by Nardi (57.8%). (11)
In 2009, Barbosa evaluated 304 patients in two cities from northeast Brazil, and observed that only 11% of individuals were above the cut-off on the Participation Scale (12 points). (15) Rafael observed that 53-33% of the 75 evaluated patients had some social restriction and that there was no association between the degree of physical disability and the scores on the Participation Scale. (27) This increased percentage found in Rafael's study may be explained by the fact that the Participation Scale was applied during MDT and, during this period, it may reflect the moment when the patient is more fragile and refusing to accept the diagnosis of the disease.
Decentralization of care to Primary Health Care units may allow for the continuity of access and care near the home. In order for this proposal to become a reality, it is necessary to invest in the process of continuing education for the technicians of the basic network, which may include training by various specialists, including the dermatologist and occupational therapist. This strategy moves from the specialist to the generalist thus increasing the capacity of Primary Health Care and establishing criteria for the flows of referrals and counter-referrals. (12)
The Participation Scale is fundamental during the MDT period, demonstrating all the feelings of the patient in reclusion, the fear and the anxiety due to the diagnosis. Otherwise, we cannot infer that the social restriction suffered by this individual is exclusively due to leprosy. Thus, there is a need to qualitatively evaluate the context of the patient.
As limitations to this study, we may highlight the selective patient population, the cross-sectional nature of the study, the operational difficulties in finding the addresses of some patients during the home visits, the quality of the medical records that prevented the analysis of socio-demographic variables such as income and level of education and the absence of ocular evaluation.
As recommendations, we suggest the implementation of the SALSA and Participation Scales in routine health services during MDT treatment; the inclusion of muscle strength evaluation as a criterion for evaluating the degree of physical disability; the performance of prevention measures during routine self-care groups and measures of prevention, monitoring and rehabilitation of physical disabilities, concomitantly with the pharmacological treatment; and the intensification of training in 'preventive and reconstructive surgery in leprosy'. In the context of eliminating this endemic disease, it is essential to consider the demand after discharge from MDT regarding limitations of activities and restriction of social participation.
