Satisfação profissional dos enfermeiros especialistas em enfermagem de reabilitação

Introdução: Portugal enfrenta, actualmente, um período de mudanças profundas nos seus pilares sociais, económicos e organizacionais, sendo o sector da saúde um dois envoltos neste processo de mudança, o qual provoca, inevitavelmente, stress, emoções e ajustamentos de vária ordem. A avaliação da satisfação dos profissionais é assim um fator chave na mensuração dos efeitos destas alterações, daí que o objetivo deste estudo seja conhecer a satisfação profissional dos enfermeiros especialistas de Reabilitação, e seus determinantes de contexto pessoal, profissional e organizacional. Método: Realizou-se um estudo transversal, descritivo-correlacional, de natureza quantitativa, no qual participaram 141 Enfermeiros, Especialistas em Enfermagem de Reabilitação, em funções em instituições públicas e privadas na zona centro do País, na sua maioria do sexo feminino (58.87%) e com uma média de idades de 40.43 anos (Dp=7.49 anos). Para a mensuração das variáveis recorreu-se a uma ficha sociodemográfica e profissional, Escala de Avaliação da Satisfação no Trabalho (EASTEnf) e Escala de Empenhamento Atitudinal, ambas validadas para a população portuguesa. Resultados: Constatou-se que a maioria dos especialistas em Enfermagem de Reabilitação apresentam um nível regular de satisfação (70,92%). Os resultados obtidos evidenciam a existência de um efeito significativo das variáveis género, estado civil, experiência profissional, perfil de cuidados prestados, tipo de horário, vínculo laboral e local de trabalho, sobre o nível de satisfação dos enfermeiros. Na generalidade, são os enfermeiros do género feminino, casados, com menor experiência profissional, que prestam de cuidados especializados, que exercem funções em regime de horário fixo, que integram os quadros da instituição onde desempenham funções e que exercem a sua profissão no sector privado, aqueles que evidenciam, em algumas das dimensões da escala de avaliação da satisfação com o trabalho, níveis de satisfação profissional mais elevados. Por outro lado, constatou-se que são os enfermeiros que consideram as alterações decorrentes nos últimos dois anos benéficas para o cliente (Mean Rank= 90,04, p=0,001) a manifestar uma satisfação mais elevada; como também foi identificada uma relação estaticamente significativa (moderada e positiva) entre o empenhamento atitudinal e a satisfação dos enfermeiros (p=0,000). Conclusões: As evidências encontradas neste estudo convidam-nos a refletir sobre estratégias que possibilitem, em comunhão de esforços com o enfermeiro e organização, a obtenção de um melhor conhecimento dos determinantes da satisfação que potenciem uma intervenção com vista à sua promoção/melhoria. Palavras-Chave: Satisfação; trabalho, empenhamento atitudinal, enfermeiros, especialistas, reabilitação.

Luto nos familiares da pessoa em situação de cuidados paliativos

Enquadramento: O luto é algo complexo e abarca múltiplas dimensões que podem resultar em luto patológico. Objetivos: Determinar a prevalência de luto complicado em familiares de pessoas em situação paliativa; identificar que variáveis sociodemográficas e de contexto do luto interferem no processo de luto complicado; averiguar se há relação entre a funcionalidade familiar, satisfação quanto aos cuidados prestados ao ente querido, a sobrecarga do cuidador e o luto em familiares de pessoas em situação paliativa. Métodos: Estudo quantitativo, transversal, descritivo e correlacional, realizado numa amostra de 75 familiares de doentes em situação paliativa. Utilizou-se um Questionário Sociodemográfico; Escala de Apgar Familiar (Agostinho & Rebelo, 1988), Escala do Contexto do Luto (Cunha, 2014), Escala de Avaliação da Satisfação dos Familiares dos Doentes em Cuidados Paliativos - Escala FAMCARE (Almeida, 2012), Escala de Sobrecarga do Cuidador (Sequeira, 2010) e o Inventory of Complicated Grief (ICG) (Frade & Rocha, 2008). Resultados: Dos 75 participantes, apenas 24 (35.2%) que se encontravam pelo menos há 6 meses enlutados obtiveram uma pontuação superior a 30 no ICG, tradutora de vivência de luto complicado. Destes, 58.3% eram mulheres e 41.7% homens; na faixa etária =<49 anos (37.5%); com companheiro(a) (54.2%); 70.8% revelam funcionalidade familiar; 62.5% dos participantes perdeu um familiar direto, cujo falecimento ocorreu em 71.4% dos casos no domicílio; 83.3% dos familiares revelam sobrecarga com os cuidados; 29.2% revelam-se insatisfeitos com os cuidados prestados ao seu familiar. Conclusão: Os resultados revelam a necessidade de identificação dos fatores de risco no luto, de modo a mobilizarem-se os recursos para a promoção da vivência saudável do luto.

Aprendizagem cooperativa em crianças em idade pré-escolar

O presente relatório decorreu durante a Prática de Ensino Supervisionada do Mestrado em Educação Pré-Escolar e é um reflexo das experiências no Jardim-de-Infância da Praceta, na cidade de Portalegre. O trabalho intitulado de “A Aprendizagem Cooperativa na Educação Pré-Escolar” teve comos principais objetivos: identificar e promover competências em crianças em idade pré-escolar; desenvolver competências sociais que permitam a cooperação entre crianças em idade pré-escolar (dos 3 aos 6 anos). Para tal, foram utilizados vários instrumentos de recolha de dados, e foram várias as atividades que promovemos com as crianças de modo a podermos refletir sobre esta metodologia que se baseia na cooperação e entreajuda. Metodologicamente foi usada a investigação-ação, o que permitiu uma reflexão em todos os momentos e que se constituiu como um apoio às nossas práticas enquanto estudantes de Mestrado e enquanto futuros profissionais de educação. Utilizámos um dilema social, não moral e uma entrevista semiestruturada, a fim de compreender melhor o mundo social e as competências sociais das crianças. Os resultados enfatizam que as crianças ainda se encontram entre o nível 0 – impulsivo e o nível 1 – unilateral, ou seja, que pensam na sua satisfação pessoal e tentam apaziguar o outro, respetivamente. Utilizámos ainda uma escala de avaliação do desenvolvimento da criança, de Alberto Sousa, a fim de avaliar as competências das crianças no que diz respeito à cooperação e ao relacionamento. Neste tópico os resultados que obtivemos demonstraram que a maioria das crianças se encontram num nível 3, no que diz respeito ao Relacionamento, e que na Cooperação as crianças obtêm valores mais baixos, isto é um reflexo da idade das crianças e da sua maturidade, pois a criança pré-escolar demonstra egocentrismo.

Systematic review of outcome domains and instruments used in clinical trials of tinnitus treatments in adults

BACKGROUND: There is no evidence-based guidance to facilitate design decisions for confirmatory trials or systematic reviews investigating treatment efficacy for adults with tinnitus. This systematic review therefore seeks to ascertain the current status of trial designs by identifying and evaluating the reporting of outcome domains and instruments in the treatment of adults with tinnitus. METHODS: Records were identified by searching PubMed, EMBASE CINAHL, EBSCO, and CENTRAL clinical trial registries (ClinicalTrials.gov, ISRCTN, ICTRP) and the Cochrane Database of Systematic Reviews. Eligible records were those published from 1 July 2006 to 12 March 2015. Included studies were those reporting adults aged 18 years or older who reported tinnitus as a primary complaint, and who were enrolled into a randomised controlled trial, a before and after study, a non-randomised controlled trial, a case-controlled study or a cohort study, and written in English. Studies with fewer than 20 participants were excluded. RESULTS: Two hundred and twenty-eight studies were included. Thirty-five different primary outcome domains were identified spanning seven categories (tinnitus percept, impact of tinnitus, co-occurring complaints, quality of life, body structures and function, treatment-related outcomes and unclear or not specified). Over half the studies (55 %) did not clearly define the complaint of interest. Tinnitus loudness was the domain most often reported (14 %), followed by tinnitus distress (7 %). Seventy-eight different primary outcome instruments were identified. Instruments assessing multiple attributes of the impact of tinnitus were most common (34 %). Overall, 24 different patient-reported tools were used, predominantly the Tinnitus Handicap Inventory (15 %). Loudness was measured in diverse ways including a numerical rating scale (8 %), loudness matching (4 %), minimum masking level (1 %) and loudness discomfort level (1 %). Ten percent of studies did not clearly report the instrument used. CONCLUSIONS: Our findings indicate poor appreciation of the basic principles of good trial design, particularly the importance of specifying what aspect of therapeutic benefit is the main outcome. No single outcome was reported in all studies and there was a broad diversity of outcome instruments. PROSPERO REGISTRATION: The systematic review protocol is registered on PROSPERO (International Prospective Register of Systematic Reviews): CRD42015017525 . Registered on 12 March 2015 revised on 15 March 2016.

The diagnostic reliability of Internet-based observational kinematic gait analysis

We investigated the accuracy and reliability of observational kinematic gait assessments performed via a low-bandwidth Internet link (118 kbit/s) and a higher-speed Internet link (128 kbit/s). Twenty-four subjects were randomized to either bandwidth group. Gait was assessed with the Gait Assessment Rating Scale (GARS) in the traditional manner, which is from video-recordings, and with repeated measurements via the online method. Online assessment was found to provide as accurate a measure of gait performance as the traditional assessment (limits of agreement

Joining forces - Combining cognition-targeted motor control training with group or individual pain physiology education: A successful treatment for chronic low back pain

Chronic unremittent low back pain (LBP) is characterised by cognitive barriers to treatment. Combining a motor control training approach with individualised education about pain physiology is effective in this group of patients. This randomized comparative trial (i) evaluates an approach to motor control acquisition and training that considers the complexities of the relationship between pain and motor output, and (ii) compares the efficacy and cost of individualized and group pain physiology education. After an "ongoing usual treatment" period, patients participated in a 4-week motor control and pain physiology education program. Patients received four one-hour individualized education sessions (IE) or one 4-hour group lecture (GE). Both groups reduced pain (numerical rating scale) and disability (Roland Morris Disability Questionnaire). IE showed bigger decreases, which were maintained at 12 months (P < 0.05 for all). The combined motor control and education approach is effective. Although group education imparts a lesser effect, it may be more cost-efficient. [ABSTRACT FROM AUTHOR]

Telephone counselling for adolescent suicide prevention: Changes in suicidality and mental state from beginning to end of a counselling session

Telephone counselling is an accessible and confidential means by which distressed young people can seek help. Telephone counselling services were funded under Australia's National Youth Suicide Prevention Strategy between 1997 and 2000. In this study, the effectiveness of telephone counselling for young people seeking help in the context of suicidal ideation or intent was evaluated in an investigation of calls made by suicidal young people to a telephone counselling service. Independent raters measured callers' suicidality and mental state at the beginning and, end of 100 taped counselling sessions. Changes in suicidality and mental state were measured using a reliable rating scale developed for the study. Significant decreases in suicidality and significant improvement in mental state were found to occur during the course of counselling sessions, suggesting positive immediate impact.-Limitations of the study with respect to longer-term outcomes and the relevance of the results for suicide prevention are discussed. Notwithstanding the study limitations, the results lend support for continuing development of hotline services.

Intramuscular Olanzapine and Intramuscular Haloperidol in Acute Schizophrenia: Antipsychotic Efficacy and Extrapyramidal Safety During the First 24 Hours of Treatment

To determine the antipsychotic efficacy and extrapyramidal safety of intramuscular (IM) olanzapine and IM haloperidol during the first 24 hours of treatment of acute schizophrenia. Method: Patients (n = 311) with acute schizophrenia were randomly allocated (2:2: 1) to receive IM olanzapine (10.0 mg, n = 131), IM haloperidol (7.5 mg, n = 126), or IM placebo (n = 54). Results: After the first injection, IM olanzapine was comparable to IM haloperidol and superior to IM placebo for reducing mean change scores from baseline on the Brief Psychiatric Rating Scale (BRPS) Positive at 2 hours (-2.9 olanzapine, -2.7 haloperidol, and -1.5 placebo) and 24 hours (-2.8 olanzapine, -3.2 haloperidol, and -1.3 placebo); the BPRS Total at 2 hours (-14.2 olanzapine,-13.1 haloperidol, and -7.1 placebo) and 24 hours (-12.8 olanzapine, -12.9 haloperidol, and -6.2 placebo); and the Clinical Global Impressions (CGI) scale at 24 hours (-0.5 olanzapine, -0.5 haloperidol, and -0.1 placebo). Patients treated with IM olanzapine had significantly fewer incidences of treatment-emergent parkinsonism (4.3% olanzapine vs 13.3% haloperidol, P = 0.036), but not akathisia (1.1% olanzapine vs 6.5% haloperidol, P = 0.065), than did patients treated with IM haloperidol; they also required significantly less anticholinergic treatment (4.6% olanzapine vs 20.6% haloperidol, P < 0.001). Mean extrapyramidal symptoms (EPS) safety scores improved significantly from baseline during IM olanzapine treatment, compared with a general worsening during IM haloperidol treatment (Simpson-Angus Scale total score mean change: -0.61 olanzapine vs 0.70 haloperidol; P < 0.001; Barnes Akathisia Scale global score mean change: -0.27 olanzapine vs 0.01 haloperidol; P < 0.05). Conclusion: IM olanzapine was comparable to IM haloperidol for reducing the symptoms of acute schizophrenia during the first 24 hours of treatment, the efficacy of both being evident within 2 hours after the first injection. In general, more EPS were observed during treatment with IM haloperidol than with IM olanzapine.

WHOQOL-BREF as a measure of quality of life in older patients with depression

Objective: To assess the reliability and validity of a brief measure of quality of life recently developed by the World Health Organization, the WHOQOL-BREF, and to examine its association with a variety of clinical and sociodemographic factors in older depressed patients. Design: Cross-sectional study. Methods: Older depressed patients (N=41) underwent diagnostic assessment using the Composite International Diagnostic Interview (CIDI) and were independently assessed on a variety of measures including the WHOQOL-BREF (a 26-item self-report questionnaire generating four domain scores), Hamilton Depression Rating Scale (HAM-D); Geriatric Depression Scale (GDS); Mini-mental State Examination (MMSE); Modified Barthel Index (MBI); Instrumental activities of daily living (IADL), and measures of physical health status and social relationships. Estimates of inter-rater and test-retest reliability, and concurrent validity were made. Results: 39 subjects completed the study. The majority of subjects (94.9%) received a diagnosis of DSM-IV Major Depressive Disorder. Levels of comorbidity were high. Three of the four domains of the WHOQOL-BREF (Physical, Psychological and Environment domains) demonstrated satisfactory reliability and validity. However, the Social Relationships domain exhibited poor validity. Quality of life scores were strongly correlated with severity of depression, number of self-reported physical symptoms and self-assessed general health status. There was no relationship between diagnostic comorbidity and quality of life scores. Conclusions: The WHOQOL-BREF was successfully administered to older depressed patients although the concurrent validity of one of its four domains was poor. Quality of life scores were strongly correlated with severity of depression, raising the issue of measurement redundancy.

Using the effect size to model change in preference values from descriptive health status

Objectives: This pilot study describes a modelling approach to translate group-level changes in health status into changes in preference values, by using the effect size (ES) to summarize group-level improvement. Methods: ESs are the standardized mean difference between treatment groups in standard deviation (SD) units. Vignettes depicting varying severity in SD decrements on the SF-12 mental health summary scale, with corresponding symptom severity profiles, were valued by a convenience sample of general practitioners (n = 42) using the rating scale (RS) and time trade-off methods. Translation factors between ES differences and change in preference value were developed for five mental disorders, such that ES from published meta-analyses could be transformed into predicted changes in preference values. Results: An ES difference in health status was associated with an average 0.171-0.204 difference in preference value using the RS, and 0.104-0.158 using the time trade off. Conclusions: This observed relationship may be particular to the specific versions of the measures employed in the present study. With further development using different raters and preference measures, this approach may expand the evidence base available for modelling preference change for economic analyses from existing data.

Clinical progression and outcome of dysphagia following paediatric traumatic brain injury: a prospective study

Objectives : To provide a preliminary clinical profile of the resolution and outcomes of oral-motor impairment and swallowing function in a group of paediatric dysphagia patients post-traumatic brain injury (TBI). To document the level of cognitive impairment parallel to the return to oral intake, and to investigate the correlation between the resolution of impaired swallow function versus the resolution of oral-motor impairment and cognitive impairment. Participants : Thirteen children admitted to an acute care setting for TBI. Main outcome measures : A series of oral-motor (Verbal Motor Production Assessment for Children, Frenchay Dysarthria Assessment, Schedule for Oral Motor Assessment) and swallowing (Paramatta Hospital's Assessment for Dysphagia) assessments, an outcome measure for swallowing (Royal Brisbane Hospital's Outcome Measure for Swallowing), and a cognitive rating scale (Rancho Level of Cognitive Functioning Scale). Results : Across the patient group, oral-motor deficits resolved to normal status between 3 and 11 weeks post-referral (and at an average of 12 weeks post-injury) and swallowing function and resolution to normal diet status were achieved by 3-11 weeks post-referral (and at an average of 12 weeks post-injury). The resolution of dysphagia and the resolution of oral-motor impairment and cognitive impairment were all highly correlated. Conclusion : The provision of a preliminary profile of oral-motor functioning and dysphagia resolution, and data on the linear relationship between swallowing impairment and cognition, will provide baseline information on the course of rehabilitation of dysphagia in the paediatric population post-TBI. Such data will contribute to more informed service provision and rehabilitation planning for paediatric patients post-TBI.

Efficacy of sertraline in a 12-week trial for generalized anxiety disorder

Objective: Sertraline's efficacy and tolerability in treating generalized anxiety disorder were evaluated. Method: Adult outpatients with DSM-IV generalized anxiety disorder and a total score of 18 or higher on the Hamilton Anxiety Rating Scale were eligible. After a 1-week single-blind placebo lead-in, patients were randomly assigned to 12 weeks of double-blind treatment with placebo (N=188, mean baseline anxiety score=25) or flexible doses (50-150 mg/day) of sertraline (N=182, mean anxiety score=25). The primary outcome measure was baseline-to-endpoint change in the Hamilton anxiety scale total score. A secondary efficacy measure was the Clinical Global Impression (CGI) improvement score; response was defined as a score of 2 or less. Results: Sertraline patients had significantly greater improvement than placebo patients on all efficacy measures at week 4. Analysis of covariance of the intent-to-treat group at endpoint (with the last observation carried forward) showed a significant difference in the decrease from baseline of the least-square mean total score on the Hamilton anxiety scale between sertraline (mean=11.7) and placebo (mean=8.0). Significantly greater endpoint improvement with sertraline than placebo was obtained for mean scores on the Hamilton anxiety scale psychic factor (6.7 versus 4.1) and somatic factor (5.0 versus 3.9). The rate of responders, based on CGI improvement and last observation carried forward, was significantly higher for sertraline (63%) than placebo (37%). Sertraline was well tolerated; 8% of patients versus 10% for placebo dropped out because of adverse events. Conclusions: Sertraline appears to be efficacious and well tolerated in the treatment of generalized anxiety disorder.

The nature of anterior knee pain following injection of hypertonic saline into the infrapatellar fat pad

The infrapatellar fat pad has been implicated as a possible source of anterior knee pain. This study examined the nature, distribution and time-course of experimentally induced pain in the infrapatellar fat pad. Hypertonic saline (5%) was injected into the medial fat pad of 11 healthy individuals with no history of knee pain. Severity of pain was assessed at rest and during activity using an 11 point numerical rating scale (NRS) at regular intervals over 15-30 min following injection. Participants described the size of the pain region from a series of different sized circles while the area and type of pain was established from a body chart and the McGill pain questionnaire. The effect of pain on temperature-pain threshold and sensory thresholds of the anterior knee was assessed. Participants generally reported a deep aching pain that peaked in severity around 3 min and gradually declined over 15 min. Pain levels were not altered by clinical manoeuvres designed to impinge the fat pad. The size of the pain region was related to pain intensity. Pain was most commonly felt in the region of the fat pad medial to the patella, although some individuals reported proximal referred pain as far as the groin region. Thermal and sensory thresholds were not altered at a region close to the injection site during the experimental pain. These results suggest that nociceptive stimulation of the infrapatellar fat pad may cause anterior knee pain that is not necessarily confined locally particularly if pain is severe. This has implications for the investigation of pathological structures in patients presenting clinically with anterior knee pain and provides an experimental model of anterior knee pain.
