Caracterização da intervenção da Fisioterapia em indivíduos com dor crónica lombar, e seus resultados a nível da dor e capacidade funcional

RESUMO: Objectivo: Este trabalho teve como objectivo contribuir para o processo de adaptação cultural da Quebec Back Pain Disability Scale (QBPDS), através do estudo da sua Validade de Constructo e Poder de Resposta, e caracterizar a intervenção realizada pela fisioterapia (FT) e os resultados obtidos em utentes com dor crónica lombar (DCL). Introdução: A redução da incapacidade funcional associada à DCL é um dos principais objectivos e resultados da intervenção da FT nestes utentes. Com o intuito de proceder à sua avaliação, pode recorrer-se a um conjunto de diferentes instrumentos de medida, sendo a QBPDS uma das escalas mais utilizadas para medir a incapacidade. Embora esta tenha sido anteriormente adaptada para a população portuguesa, não foram determinadas as suas propriedades psicométricas. Por outro lado, apesar da literatura referir que os serviços de FT são bastante procurados por indivíduos com DCL, em Portugal, a informação existente sobre a prática da FT nesta condição clínica e sobre os resultados obtidos é ainda escassa. Metodologia: Recorreu-se a um estudo de coorte prospectivo com uma amostra de conveniência, constituída por 119 indivíduos com DCL, que iniciaram fisioterapia em 16 centros/ hospitais/ clínicas de Fisioterapia/ utentes no domicílio, e cumpriam os critérios de inclusão e exclusão estabelecidos. Os utentes foram avaliados no momento pré-intervenção e num segundo momento até 6 semanas depois. As propriedades psicométricas da Quebec Back Pain Disability Scale –Versão Portuguesa (QBPDS-VP) avaliadas foram a Validade de Constructo e o Poder de Resposta. Posteriormente procedeu-se à caracterizar a prática da FT quanto às modalidades utilizadas, número de sessões de tratamento e duração do episódio de cuidados. Adicionalmente descreveu-se os resultados obtidos após a intervenção da FT, ao nível da dor e incapacidade. Resultados: Os resultados revelaram um resultado positivo para a Validade de Constructo da QBPDS-VP e um elevado Poder de Resposta (área abaixo da curva ROC = 0,736; IC95%=0,639-0,833). Apresenta ainda uma diferença mínima clinicamente importante (DMCI) de 7 pontos (sensibilidade =72,4% e especificidade = 69,8%). Aquando da intervenção da FT em casos de DCL, existe uma grande diversidade de modalidades realizadas combinadas em diferentes pacotes de intervenção, e verificou-se um número médio de sessões realizadas de 14,22 visitas por utente, numa duração de episódio de cuidados maioritariamente superior a 6 semanas. Os resultados da intervenção revelaram uma redução significativa da incapacidade funcional e da intensidade da dor (z= -7,440 e z=-6,625; respectivamente, p=0,000). Conclusão: Os resultados do presente estudo revelam que a QBPDS-VP possui uma boa Validade de Constructo e Poder de Resposta. Revela ainda que a intervenção da FT em casos de DCL, apesar de apresentar grande diversidade nas modalidades utilizadas por vezes até divergentes das recomendações dadas pelas normas de orientação clínica, e uma duração do episódio de cuidados aparentemente superior aos dados fornecidos pela literatura; proporciona uma redução significativa dos níveis de dor e incapacidade em utentes com DCL.------------ ABSTRACT: Objective: The aim of this study is to contribute to the process of cultural adaptation of the Quebec Back Pain Disability Scale (QBPDS), through the study of its Construct Validity and Responsiveness, and characterize the intervention performed by physical therapy (PT) and the results in patients with chronic low back pain (CLBP). Introduction: The reduction in functional disability associated with CLBP is one of the main purpose and results of physical therapy intervention in these patients. With the intention of evaluating them, the professionals can resort to a set of different measuring instruments, and the QBPDS is one of the most commonly used scales for measuring disability. Although this has been previously adapted for the Portuguese population, it was not determined its psychometric properties. Moreover, despite the literature noted that services for PT are quite sought by individuals with CLBP, in Portugal, the existing information on the practice of PT in this clinical condition and the results obtained are still scarce. Methodology: It was used a prospective cohort study with a convenience sample consisting of 119 individuals with CLBP, who started therapy at 16 centers / hospitals / Physiotherapy clinics / household physiotherapy, and fulfiled the inclusion and exclusion criteria established . The patients were assessed at pre-intervention and a second time after 6 weeks. Psychometric properties of the Quebec Back Pain Disability Scale-Portuguese version (QBPDS-VP) were evaluated to construct validity and responsiveness. Subsequently, it was proceeded to the characterization the practice of FT regarding to the modalities used, the number of treatment sessions and duration of the episode of care. Additionally it was described the results obtained after the intervention of the PT, the level of pain and the disability. Results: The results revealed a positive result for the Construct Validity of the QBPDS- VP and a high responsiveness (area under the ROC curve = 0.736, 95% CI 0.639 to 0.833). Minimal clinically important difference (MCID) also presents a 7-point (sensitivity = 72.4% and specificity = 69.8%). In the PT intervention in cases of CLBP there is a great diversity of procedures performed combined in different packages intervention, and it was found an average number of sessions of 14.22 visits per user, with a duration of the episode of care mostly higher to 6 weeks. The results of the intervention showed a significant reduction of disability and pain intensity (z = -7.440 z = -6.625, respectively, p = 0.000).Conclusion: The results of this study show that QBPDS-VP has a good construct validity and responsiveness. It also reveals that the PT intervention in cases of CLBP, despite showing great diversity in the methods used, that sometimes are also divergent to the recommendations given by clinical guidelines, and with a duration of episode of care apparently superior to data provided by the literature, provides an significant reduction in the levels of pain and disability in patients with DCL.

Saúde Mental em meio prisional : avaliação de necessidades de cuidados em reclusos com perturbação mental

RESUMO: A população prisional é constituída por indivíduos geralmente sujeitos a alguma forma de exclusão social e que apresentam problemas de saúde física e mental mais frequentes do que na população em geral. A prevalência mais elevada de perturbações mentais e de suicídio nos reclusos, em relação à população civil, é consensual e está demonstrada em numerosos estudos internacionais. O abuso/dependência de substâncias, a depressão, as psicoses e a perturbação anti-social de personalidade são as perturbações mais comuns na população prisional. As perturbações mentais são importantes factores de risco de suicídio, de vitimização, de reincidência e de reentrada no sistema prisional. Assim sendo, o grupo de reclusos com perturbação mental constitui um grupo de risco relevante. A avaliação de necessidades de cuidados foi iniciada no Reino Unido como um método para o planeamento, medição dos resultados e financiamento dos cuidados de saúde. Para esta avaliação foram desenvolvidos instrumentos que avaliam as necessidades em diversos domínios (clínicos e sociais) para aplicação aos utentes, cuidadores e profissionais. Até aos anos noventa, a avaliação de necessidades no contexto prisional incidia especialmente nas necessidades de segurança dos serviços, segundo a perspectiva dos profissionais. Contudo, a partir do relatório Reed (1992), sobre a situação dos reclusos com perturbação mental, verificou-se uma abordagem mais abrangente, que incluía a avaliação das necessidades de cuidados dos reclusos. Embora as necessidades dos reclusos com perturbação mental pareçam ser similares às dos doentes psiquiátricos em geral, existem diferenças em determinados domínios como a comorbilidade do eixo II, o abuso de substâncias e o risco de violência. Por este motivo, as necessidades de cuidados de saúde mental dos reclusos são elevadas e frequentemente não se encontram satisfeitas. De forma a incluir estas especificidades foi desenvolvida a versão forense do Camberwell Assessment of Need (CAN), designada por CAN - Forensic Version (CANFOR). Actualmente existe um consenso generalizado entre as instituições internacionais do dever de proporcionar aos reclusos cuidados de saúde, de prevenção e de tratamento, equivalentes aos cuidados disponíveis para a população civil - o princípio da equivalência de cuidados. A presente investigação pretendeu caracterizar e avaliar as necessidades de cuidados dos reclusos acompanhados nos serviços de psiquiatria prisionais na área da Grande Lisboa (internamento no Serviço de Psiquiatria do Hospital Prisional de S. João de Deus (HPSJD) e consultas nos Estabelecimentos Prisionais (EP) de Caxias e de Tires). De modo a estabelecer uma comparação com sujeitos civis foi seleccionada uma amostra de conveniência de pacientes acompanhados num departamento de psiquiatria da mesma região, segundo um emparelhamento por sexo, escalão etário, e por diagnóstico, num período de 3 meses. Realizou-se um estudo de tipo observacional, transversal e comparativo. Aplicaram-se os seguintes instrumentos de avaliação: questionário específico, Brief Psychiatric Rating Scale 4.0, Mini International Neuropsychiatric Interview 5.0.0, Global Assessment Functioning, CAN-R e CANFOR-R. No período do estudo (12 meses) foram assistidos 149 reclusos, dos quais, 35 (23,5%) não cumpriram os critérios de inclusão. A amostra final de reclusos (PRs) (n=114) foi constituída por 79 homens (69,3%) e 35 mulheres (30,7%), dos quais 77 eram condenados (67,5%) e 37 (32,5%) encontravam-se detidos preventivamente. A amostra final de participantes civis (PCs) foi constituída por 121 indivíduos, dos quais 76 eram homens (62,8%) e 45 eram mulheres (37,2%).A amostra final de participantes civis (PCs) foi constituída por 121 indivíduos, dos quais 76 eram homens (62,8%) e 45 eram mulheres (37,2%). Relativamente aos PRs, o diagnóstico mais frequente foi a Perturbação Anti-social da Personalidade (57,9%), seguida pela Depressão Major (56,1%). A maioria (53,5%) apresentava três ou mais categorias diagnósticas. Aproximadamente um terço dos PRs (30%) pontuou o nível elevado de risco de suicídio. A probabilidade deste risco aumentava, significativamente, nos portadores de Depressão Major, de um maior nível de psicopatologia e de uma condenação actual. Perto de metade dos PRs (47,4%) possuía duas ou mais condenações prévias e mais de metade estavam envolvidos em crimes contra pessoas (53,5%). A probabilidade de condenações múltiplas foi significativamente superior nos portadores de Perturbação Antisocial da Personalidade e nos reclusos com maior número de necessidades totais. Entre os PRs dos dois sexos, as principais diferenças significativas residiram na maior frequência de consumo de substâncias e no maior número de necessidades de cuidados nãosatisfeitas nos homens versus mulheres. A comparação entre os PRs, antes da detenção, e os PCs mostrou que os primeiros possuíam menor escolaridade, menos medicação psiquiátrica, mas mais emprego e mais consumos de substâncias ilícitas. A Perturbação Anti-social da Personalidade (OR=26,4; IC95%: 10,7-64,9), a Perturbação Pós-stress Traumático (OR=15,0; IC95%: 3,5-65,4), a Dependência/Abuso de Substâncias (OR=8,5; IC95%: 4,2-17,6) a Depressão Major (OR=2,6; IC95%: 1,5-4,4) e o Risco de Suicídio Elevado (OR=2,6; IC95%: 1,4-5,0) foram significativamente mais frequentes nos PRs versus PCs. Relativamente à avaliação de necessidades de cuidados, os PRs mostraram maior número de necessidades não-satisfeitas e maior necessidade de ajuda profissional, em relação aos PCs. Embora diversas necessidades não-satisfeitas possam resultar da condição de recluso, outras, em domínios da saúde física, da segurança do próprio e dos consumos tóxicos, poderão indicar que os PRs recebem um nível de cuidados inferior ao necessário, em comparação com os PCs. Os PRs apresentaram patologia mental, predominantemente não-psicótica e elevado risco de suicídio/auto-agressão, associado a depressão, necessidades de cuidados e uma pena de prisão. Possuíam, numa frequência elevada, características, consistentemente, associadas à reincidência criminal (personalidade anti-social, consumos tóxicos, condenações anteriores), pelo que se justifica um especial acompanhamento deste grupo, no período pré e pós-libertação. A comparação de necessidades de cuidados no contexto civil e prisional indica um maior nível de necessidades e um menor nível de cuidados recebidos pelos PRs, em relação aos PCs. O princípio da equivalência de cuidados poderá estar comprometido nos indivíduos reclusos com perturbação mental. A utilização do CANFOR foi fácil e poderá contribuir para um melhor planeamento, oferta e avaliação de resultados ao nível individual. Os PRs e PCs revelaram características clínicas e de necessidades muito diferentes entre si, pelo que, os reclusos com perturbação mental deverão ser assistidos em serviços de saúde mental preparados para abordar as suas especificidades.---------------ABSTRACT: The prison population is generally made up of individuals who are usually subject to some sort of social exclusion and who show physical and mental problems more frequently than the general population. Various international studies have found higher rates of mental disturbances and suicide within the prison population. The most common mental disturbances found are substance abuse or dependency, depression, psychosis, and anti-social personality disturbance. Such mental disturbances are important factors in suicide, victimization, delinquency recurrence, and the risk of reentry into prison. As a result, prison inmates with mental disturbances are a relevant at risk group. Assessment of needs of care first started in the United Kingdom as a method of care planning, results measuring and finance health care. The method involved the development of certain measuring instruments to be used by patients, caregivers and professionals in order to evaluate needs in various domains (clinical and social). Until the nineties, the assessment of needs of care in a prison context focused mainly on the service’s security needs. However, after the Reed (1992) report on mentally disturbed inmates, a much wider approach was considered, which included evaluation of the inmate’s needs of care. However similar mentally disturbed prison inmates’ needs may appear to those of other psychiatric patients, there are some differences in particular domains, namely, co-morbidity of Axis II, substance abuse and the risk of violence. For this reason, inmates’ mental health care needs are high and very often not met. In order to include these specificities, a forensic version of the Camberwell assessment of need (CAN,) designated CAN – Forensic version (CANFOR) was developed. There is now generalized consensus among international institutions of the duty under the equivalent health care principle to provide inmates with preventative health care and treatment, that are equivalent to the care available to the civil population. This investigation aims to characterize and assess the health care provision of prison inmates admitted to Lisbon’s Psychiatric Prison ward - the Psychiatric Ward of São João de Deus Hospital (HPSJD) - and inmates in the Caxias and Tires Prison Establishments (EP) undertaking outpatient treatment. In order to establish a comparison between prison and civilian patients, a convenience sample was selected from civilian patients being treated in a psychiatric ward in the same geographical area. This sample was paired by gender, age group and diagnosis during a three month period. The study was observational, transversal and comparative. The following measuring instruments were used: a purpose-built questionnaire, Brief Psychiatric Rating Scale 4.0, Mini International Neuropsychiatric Interview 5.0.0, Global Assessment Functioning Scale, CAN-R and CANFOR-R. During the research period (12 months), 149 inmates received care, of whom 35 (23.5%) did not comply with the prerequisite criteria of this study. The final sample of inmates (PRs) (n=114) comprised 79 men (69.3%) and 35 (30.7%) women, of whom 77 (67.5%) were convicted prisoners and 37 (32.5%) were in preventive custody. The final sample for Civilian Participants (PCs) was made up of 121 individuals, of whom 76 (62.8%) were men and 45 (37.2%) were women. The most common diagnosis among the PRs was Anti-Social Personality Disorder (57.9%), followed by Major Depression (56.1%). More than half of the subjects in the sample (53.5%) showed three or more diagnostic categories. Approximately one third (30%) of the PRs showed a high level of suicide risk. The probability of this risk was significantly higher among Major Depression patients, those showing a higher level of psychopathology and those with a current conviction. Almost half of the PRs (47.4%) had been given two or more prior convictions and more than half (53.5%) were involved in crimes against people. The probability of multiple convictions was significantly higher among inmates with Anti-Social Personality Disorder and in those with more total needs. With regard to gender, the main significant difference among the PRs was that men were found to have a higher frequency of substance use and a greater number of unsatisfied caring needs than women. Comparison between the PRs prior to detention and PCs revealed that the former held lower educational qualifications and received less psychiatric medication, but had higher levels of employment and showed greater consumption of illicit substances. In addition Anti-Social Personality Disorder (OR=26.4; IC 95%: 10.7-64.9), Post-Stress Traumatic Disturbance (OR=15.0; IC 95%: 3.5-65.4), Substance Dependency/Abuse (OR=8.5; IC 95%: 4.2-17.6), Major Depression (OR=2.6; IC 95%: 1.5-4.4), and High Suicide Risk (OR=2.6; IC 95%: 1.4-5.0) were significantly more frequent amongst PRs than PCs. The results for needs assessment revealed that the PRs showed higher levels of unmet needs and a greater need for professional help in comparison with the PCs. Although various unmet needs may result from the inmate’s condition, other needs - in particular those regarding physical health, personal security and toxic substance use - suggest that the care given to PRs may be inadequate in comparison with that given to PCs. This implies that the principle of equivalent health care for PRs with mental illnesses may not be upheld. Furthermore, the mental morbidity results of the PRs indicated that they suffer predominantly from non-psychotic and high suicide/self inflicted aggression risk associated with depression, caring needs and a prison sentence. They also often showed characteristics that are consistently associated with criminal recidivism (Anti-social Personality, use of toxic substances, prior convictions). This result justifies that there should be special follow-up for this group in the pre- and after release period. The use of CANFOR proved to be simple and the application delay was acceptable. No difficulties were encountered in the understanding of its categories by its users. As a result, itcould contribute towards better planning, supply and assessment of results at an individual level. Given that the PRs and PCs revealed different clinical and needs characteristics, it is recommended that inmates with mental disturbances should be assisted in mental health services that are adequately prepared to address their specificities.

Internet Geography: New Spaces of Information

The objective of great investments in telecommunication networks is to approach economies and put an end to the asymmetries. The most isolated regions could be the beneficiaries of this new technological investments wave disseminating trough the territories. The new economic scenarios created by globalisation make high capacity backbones and coherent information society polity, two instruments that could change regions fate and launch them in to an economic development context. Technology could bring international projection to services or products and could be the differentiating element between a national and an international economic strategy. So, the networks and its fluxes are becoming two of the most important variables to the economies. Measuring and representing this new informational accessibility, mapping new communities, finding new patterns and localisation models, could be today’s challenge. In the physical and real space, location is defined by two or three geographical co-ordinates. In the network virtual space or in cyberspace, geography seems incapable to define location, because it doesn’t have a good model. Trying to solve the problem and based on geographical theories and concepts, new fields of study came to light. The Internet Geography, Cybergeography or Geography of Cyberspace are only three examples. In this paper and using Internet Geography and informational cartography, it was possible to observe and analyse the spacialisation of the Internet phenomenon trough the distribution of the IP addresses in the Portuguese territory. This work shows the great potential and applicability of this indicator to Internet dissemination and regional development studies. The Portuguese territory is seen in a completely new form: the IP address distribution of Country Code Top Level Domains (.pt) could show new regional hierarchies. The spatial concentration or dispersion of top level domains seems to be a good instrument to reflect the info-structural dynamic and economic development of a territory, especially at regional level.

Internet Geography: Spaces of Innovation

Information Society plays an important role in all kinds of human activity, inducing new forms of economic and social organization and creating knowledge. Over the last twenty years of the 20th century, large investments in telecommunication networks were made to approach economies and put an end to the asymmetries. The most isolated regions were the beneficiaries of this new technological investment’s wave disseminating trough the territories. The new economic scenarios created by globalisation make high capacity backbones and coherent information society polity, two instruments that could change regions fate and launch them in to an economic development context. Technology could bring international projection to services, products and could be the differentiating element between a national and an international economic strategy. So, the networks and its fluxes are becoming two of the most important variables to the economies. Measuring and representing this new informational accessibility, mapping new communities, finding new patterns and localisation models, could be today’s challenge. In the physical/real space, location is defined by two or three geographical co-ordinates. In the network/virtual space or in cyberspace, geography seems incapable to define location, because it doesn’t have a good model. Trying to solve the problem and based on geographical theories and concepts, new fields of study came to light. Internet Geography is one example. In this paper and using Internet Geography and informational cartography, it was possible to observe and analyse the spacialisation of the Internet phenomenon trough the distribution of the IP addresses in the Portuguese territory. This work shows the great potential and applicability of this indicator to regional development studies, and at the same time. The IP address distribution of Country Code Top Level Domains (.pt for Portugal) could show the same economic patterns, reflecting territorial inflexibility or, by opposition, new regional hierarchies. The spatial concentration or dispersion of top level domains seems to be a good instrument to analyse the info-structural dynamic and economic development of a territory, especially at regional level. At the same time it shows that information technologies are essential to innovation and competitive advantage.
