Development of an intervention to prevent back pain in nurses and nursing students

Anna Dawson Unknown Date (has links)
Nurses report high rates of back pain with consequent disability, work absenteeism and attrition from the profession. In the current climate of an international nursing shortage, efficacious interventions to reduce the impact of back pain must be developed. It is uncertain what components a back pain preventive intervention should comprise. Appropriate and reliable means to assess back pain and disability in nurses is also undetermined. The first aim of this thesis was to undertake a mixed methods program of research to inform the development of an intervention to prevent back pain in nurses. The second aim of the thesis was to examine the psychometric and measurement properties of back pain and disability outcome instruments frequently applied in nursing samples. Epidemiological studies were undertaken to examine factors associated with back pain in nursing cohorts. In student nurses, a history of manual handling work was found to be significantly associated with neck and back pain outcomes. In a large population cohort study of nurses and midwives, pain characteristics (pain severity and radiation), pain-related cognitive and behavioural factors (kinesiophobia and passive pain coping), job characteristics (job classification and manual handling task frequency) as well as demographic interactions explained sick leave due to back pain. A systematic review was undertaken to determine the efficacy of interventions aiming to prevent back pain and back injury in nurses. Due to methodological heterogeneity, a qualitative synthesis of evidence was undertaken on the 16 studies that met inclusion criteria. The review identified moderate level evidence from multiple trials that manual handling training in isolation is not effective and multidimensional interventions are effective in preventing back pain and injury in nurses. Single trials provided moderate evidence that stress management programs do not prevent back pain and limited evidence that lumbar supports are effective in preventing back injury in nurses. There was conflicting evidence regarding the efficacy of exercise interventions and the provision of manual handling equipment and training. A qualitative description study was employed to explore the beliefs and perceptions of nursing stakeholders regarding risk factors for back pain and strategies to prevent back pain in nurses. Stakeholders identified individual, intrapersonal, organisational and environmental risk factors that were consistent with the social ecological view of health. They believed that interventions targeting the individual would be ineffective in the absence of workplace and other reforms. At the individual level, they recommended strategies that address physical, psychological and occupational preparedness for nursing work. In addition, they suggested ecological intervention strategies to induce change at the intrapersonal, organisational, community and policy levels. A mixed method synthesis of evidence was performed to develop an evidence-based and stakeholder-relevant intervention that aims to reduce the impact of back pain in nurses. The proposed intervention incorporates evidence-based multidimensional strategies that address individual and organisational level factors, and proposes ecological factors that may warrant inclusion once evidence of their causal association with back pain is established. Methodological studies examined the psychometric and measurement properties of key instruments used to assess back pain and disability in nursing populations. An extended version of the Nordic Musculoskeletal Questionnaire – that is frequently modified when applied in nursing cohorts - was developed and deemed to have acceptable test-retest reliability. The Oswestry Disability Index was found to have unacceptable measurement properties for application in nursing samples, and is therefore not recommended for future studies of back pain related disability in the nursing population. In summary, this program of research contributes novel insights that can meaningfully inform understanding of back pain prevention in nurses. Factors not previously assessed in nursing populations have been examined and shown to be significantly related to back pain outcomes. The strength of existing evidence for the prevention of back pain and injury in nurses has been established, and methodological advances regarding appropriate and reliable measurement of back pain and disability have been made. The views and perceptions of stakeholders from multiple levels and vantage points have been considered and integrated within the interpretation of evidence from multiple mixed method studies. In fact, stakeholders have played a crucial role in the identification of an appropriate theoretical framework – the social ecological paradigm - to conceptualise back pain causality in nurses and identify relevant solutions. A future research agenda of expanded scope is implicated to adequately address back pain prevention in nurses.

Classroom behaviour management to support children's social, emotional, and behavioural development

Nye, Elizabeth January 2017 (has links)
<b>Introduction:</b> Children's social, emotional, and behavioural difficulties are associated with reduced academic performance, stressed teacher-child relationships, and other negative academic and life outcomes. The Incredible Years Teacher Classroom Management (IY TCM) programme is one intervention developed to address problematic behaviours via training teachers to use positive and proactive management strategies. The overall aim of this DPhil is to use the Incredible Years Teacher Classroom Management programme as a case study for applying mixed methods at the systematic review level to ascertain what is known about both the programme's effectiveness and how people experience the course, and subsequently to use the systematic review's findings as a springboard (rather than as an end goal) for more exploratory research into 'for whom' the programme might work. <b>Method:</b> Study One is a mixed methods systematic review of IY TCM. It applied multilevel meta-analysis to RCT outcome data and grounded theory meta-synthesis to interview and focus group data on stakeholders' experiences of IY TCM. Quantitative and qualitative findings were cross-synthesised and mapped using an integrative grid. Study Two moves the field forward by filling a gap in the evidence base, as identified in Study One. Semi-structured telephone interviews were conducted with special educational needs coordinators (SENCos) across Devon, exploring the acceptability and appropriateness of expanding IY TCM to the subgroup of children with special educational needs (SEN) in mainstream schools. Data were analysed thematically and mapped onto IY TCM content. <b>Results:</b> In Study One, nine studies reported across 14 papers met inclusion criteria for either quantitative or qualitative strands of this systematic review. Multilevel meta-analysis of RCTs (n=4) indicated that the programme produced teacher- and child-level results in the desired directions. Clear trends across all measured outcomes favoured the intervention group over the treatment-as-usual comparison. Qualitative meta-synthesis (n=5) illuminated a cyclical learning process and broader conceptualisation of teacher and child outcomes than was evident in the quantitative evidence. Notably, RCT data on teacher outcomes were limited to self-reported or observed behaviours, while teachers described other benefits from IY TCM including increased knowledge and emotional well-being. Cross-synthesis of findings from the two review strands highlighted harmony across the RCT and qualitative evidence but also a number of areas in which constructs that were prioritised by one type of research were not integrated into the other. Study Two generated classroom management strategies from SENCos, which aligned closely with strategies taught in IY TCM, indicating that IY TCM would be both acceptable and applicable (if not sufficient) for use when working with children identified with SEN and behavioural difficulties in schools. <b>Discussion:</b> Based on the positive effects of implementing IY TCM despite very few studies to power analyses, the programme appears to offer tangible benefits to both teachers and children. It is possible that results are underestimated due to limited types of outcomes measured and absence of experiential data from additional stakeholders (e.g., parents). Depending on current provision of special educational needs services, schools operating inclusion models are likely to find these strategies beneficial for children identified with SEN, and this subgroup should be explicitly examined in future IY TCM studies.

Competing risks methodology in the evaluation of cardiovascular and cancer mortality as a consequence of albuminuria in type 2 diabetes

Feakins, Benjamin January 2016 (has links)
<b>Background:</b> 'Competing risks' are events that either preclude or alter the probability of experiencing the primary study outcome(s). Many standard survival models fail to account for competing risks, introducing an unknown level of bias in their measures of absolute and relative risk. Individuals with type 2 diabetes mellitus (T2DM) and albuminuria are at increased risk of multiple competing causes of mortality, including cardiovascular disease (CVD), cancer and renal disease, yet studies to date have not implemented competing risks methodology. <b>Aim:</b> Using albuminuria in T2DM as a case study, this Thesis set out to quantify differences between standard- and competing-risks-adjusted survival analysis estimates of absolute and relative risk for the outcomes of cardiovascular and cancer mortality. <b>Methods:</b> 86,962 patients aged &ge;35 years with T2DM present on or before 2005 were identified in the Clinical Practice Research Datalink. To quantify differences in measures of absolute risk, cumulative risk estimates for cardiovascular and cancer mortality from standard survival analysis methods (Kaplan-Meier estimator) were compared to those from competing-risks-adjusted methods (cumulative incidence competing risk estimator). Cumulative risk estimates were stratified by patient albuminuria level (normoalbuminuria vs albuminuria). To quantify differences in measures of relative risk, estimates for the effect of albuminuria on the relative hazards of cardiovascular and cancer mortality were compared between standard cause-specific hazard (CSH) models (Cox-proportional-hazards regression), competing risk CSH models (unstratified Lunn-McNeil model), and competing risk subdistribution hazard (SDH) models (Fine-Gray model). <b>Results:</b> Patients with albuminuria, compared to those with normoalbuminuria, were older (p&LT;0.001), had higher systolic blood pressure (p&LT;0.001), had worse glycaemic control (p&LT;0.001), and were more likely to be current or ex-smokers (p&LT;0.001). Over the course of nine years of follow-up 22,512 patients died; 8,800 from CVD, 5,239 from cancer, and 8,473 from other causes. Median follow-up was 7.7 years. In patients with normoalbuminuria, nine-year standard and competing-risks-adjusted cumulative risk estimates for cardiovascular mortality were 11.1% (95% confidence interval (CI): 10.8-11.5%) and 10.2% (95% CI: 9.9-10.5%), respectively. For cancer mortality, these figures were 8.0% (95% CI: 7.7-8.3%) and 7.2% (95% CI: 6.9-7.5%). In patients with albuminuria, standard and competing-risks-adjusted estimates for cardiovascular mortality were 21.8% (95% CI: 20.9-22.7%) and 18.5% (95% CI: 17.8-19.3%), respectively. For cancer mortality, these figures were 10.7% (95% CI: 10.0-11.5%) and 8.6% (8.1-9.2%). For the effect of albuminuria on cardiovascular mortality, hazard ratios from multivariable standard CSH, competing risks CSH, and subdistribution hazard ratios from competing risks SDH models were 1.75 (95% CI: 1.63-1.87), 1.75 (95% CI: 1.64-1.87), and 1.58 (95% CI: 1.48-1.69), respectively. For the effect of albuminuria on cancer mortality, these values were 1.27 (95% CI: 1.16-1.39), 1.28 (95% CI: 1.17-1.40), and 1.11 (95% CI: 1.01-1.21). <b>Conclusions:</b> When evaluating measures of absolute risk, differences between standard and competing-risks-adjusted methods were small in absolute terms, but large in relative terms. For the investigation of epidemiological relationships using relative hazards models, standard survival analysis methods produced near-identical risk estimates to the CSH competing risks methods for the clinical associations evaluated in this Thesis. For the evaluation of risk prediction using relative hazards models, CSH models produced consistently higher risk estimates than SDH models, and their use may lead to over-estimation of the predictive effect of albuminuria on either outcome. Where outcomes are less common (like cancer) CSH models provide poor estimates of risk prediction, and SDH models should be used. This research demonstrates that differences can be present between risk estimates derived using CSH and SDH methods, and that the two are not necessarily interchangeable. Moreover, such differences may be present in other clinical areas.

A mixed methods investigation of behavioural determinants relating to medication error reporting by health professionals in the United Arab Emirates

Alqubaisi, Mai January 2016 (has links)
Improving the effectiveness and efficiency of medication error reporting is key to enhancing patient safety. The aim of this research was to explore medication error reporting in the United Arab Emirates (UAE), examining the attitudes, beliefs, behaviors and experiences of health professionals. The first phase was a Joanna Briggs Institute registered systematic review of the beliefs, attitudes and experiences of health professionals relating to medication error reporting. Findings indicated the need for original research employing a mixed methods approach to quantify and generate in-depth information, grounded in theories of behaviour change. In the second phase, a cross-sectional survey of health professionals in the UAE was conducted to determine the behavioural determinants and facilitators and barriers of medication error reporting. Principal component analysis of responses from 294 health professionals identified six components: knowledge and skills related; feedback and support related; action and impact related; motivation related; effort related; and emotions. Responses were neutral for the motivation and effort related components, but negative for the emotions component. Comparison of component scores identified that, nurses, females, those with greater experience and being older were more likely to be positive in their responses (p<0.05). In terms of emotions, the component with the lowest scores, older respondents with greater experience gave more positive responses (p<0.05). In the final phase, face-to-face semi-structured interviews with 29 health professionals explored in-depth the behavioural determinants of medication errors reporting in the UAE. The theoretical domains framework was employed in constructing the interview schedule and interpreting the findings. ‘Goals’ and ‘intentions’ were determinants which acted as facilitators while ‘beliefs of the consequences’, ‘emotions’,’ ‘social influences and environmental context’ were barriers. This doctoral research has generated original findings which can support the development of interventions, based on behaviour change techniques, to enhance medication error reporting. These changes could impact at the levels of the organisation, health professional and patient.

Correlates of the depression and hopelessness relationship in older adults : a systematic review and empirical investigation in a rural community sample

Cameron, Shri January 2018 (has links)
Background: Links between later life depression (LLD) and adverse health outcomes are well-documented, with mental ill-health in rural older adults highlighted as a priority area for health care policy. In working age adults, models of depression show that specific psychological factors (e.g. hopelessness, neuroticism, extraversion and insecure attachment) interact with life stress to increase risk of depression. In older adults, however, the direct relationship between depression and hopelessness is inconsistently replicated. In addition, there is little evidence regarding how psychological factors interact with vulnerability to depression in older adults; and whether these factors act in the same manner as they do in working age adults. Objectives: A systematic review was carried out in order to determine the strength of the depression-hopelessness relationship, and the influence of personality traits (neuroticism/ extraversion) and insecure attachment (anxious/ avoidant) on this relationship. Next, an exploratory study was carried out to determine whether there was a direct relationship between depression and hopelessness in rural older adults living in the community and, secondly, whether this relationship was indirectly influenced by specific psychological factors (e.g. neuroticism, extraversion, and attachment styles). Methods: The systematic review was carried out using several databases (Psychinfo, Science Direct, EBCOS, Cohrane Library, PROSPERO, WEBCAT and Google Scholar). Studies relating to the variables of interest, meeting inclusion and exclusion criteria, were reviewed and evaluated for methodological biases. The pilot study asked older adults (N = 58) living in a remote and rural region to complete and return a packet of self-report questionnaires (Big Factor Inventory-10, Experiences in Close Relationships, Depression, Anxiety and Stress Scale, and the Beck Hopelessness Scale). Results: The systematic review identified twenty-one studies; four examining the depression-hopelessness relationship and seventeen investigating the effects of neuroticism, extraversion and insecure attachment styles on wellbeing, depression and/ or hopelessness. Findings from the pilot showed a direct relationship between depression and hopelessness in rural community dwelling older adults, with only neuroticism indirectly influencing this relationship. Conclusions: The systematic review suggests that it is not possible, as yet, to draw robust conclusions from the existing evidence base regarding the influence of psychological variables on depression and hopelessness in older adults. The findings were particularly sensitive to methodological limitations (e.g. variability between sampling methods and small effect sizes). Despite this, studies suggest some evidence for attachment and personality influencing on the depression-hopelessness relationship. Likewise, findings from the pilot study are limited by the small sample size and cross-sectional nature of the data. Preliminary findings, however, suggest that neuroticism, and not beliefs about insecure attachment, strengthens the relationship between depression and hopelessness in non-clinical, rural older adults. These findings are consistent with research on working age adults and could, potentially, represent an emerging relationship in non-clinical older adults. Further research, however, is required as to whether the same patterns are observed in clinical populations.

Também avaliamos como análise de subgrupos as paralisias transitórias e permanentes em grupo de pacientes de alto e baixo risco de injúria do NLR. Resultados: Quatro ensaios clínicos randomizados envolvendo 1.379 pacientes submetidos à tireoidectomia utilizando a neuromonitorização ou com a identificação somente do NLR, sendo 2.605 o número total de nervos em risco foram avaliados. A neuromonitorização diminuiu o risco do total paralisias (transitórias e permanentes) de prega vocal em tireoidectomias (RR 0,64; IC 95% de 0,43 a 0,95, I 2 = 30%), assim como diminuiu o risco de paralisias transitórias (RR 0,60; IC 95% de 0,38 a 0,95, I 2 =10%), porém não diminuiu o risco de paralisias permanentes (RR 0,84; IC 95% de 0,36 a 1,93, I 2 = 0%). A análise da média do tempo de cirurgia foi conduzida em dois estudos, entretanto como a heterogeneidade entre os estudos foi maior que 75% a metanálise não foi apropriada para estabelecer a diferença do tempo médio de cirurgia entre os grupos. Quanto a análise de subgrupos, observou-se que a neuromonitorização não diminuiu o risco de paralisias transitórias (RR 0,61; IC 95% de 0,28 a 1,31, I 2 = 0%) e nem o risco de paralisias permanentes de prega vocal em tireoidectomias de baixo risco (RR 1,03; IC 95% de 0,21 a 5,07, I 2 não aplicável). Assim como também não diminuiu o risco de paralisias transitórias (RR 0,75; IC 95% de 0,18 a 3,07, I 2 = 71%) e de paralisias permanentes de prega vocal em tireoidectomias de alto risco (RR 0,69; IC 95% de 0,27 a 1,79, I 2 = 4%). Conclusões: Essa meta-análise utilizando apenas ensaios clínicos randomizados demonstrou que a neuromonitorização do nervo laríngeo recorrente em tireoidectomias possivelmente reduz ligeiramente o risco de paralisia transitória das pregas vocais, mas provavelmente faz pouca ou nenhuma diferença no risco de paralisia permanente. / Introduction: Vocal cord paralysis is characterized as one of the main complications and sequels after thyroidectomy.

A systematic review and meta-analysis was done using the fixed-effects model. GRADE was used to classify the quality of the evidence. The primary endpoints evaluated were the total nerve paralysis for nerves at risk, transient and permanent paralyzes, and surgery time comparing the two techniques. As secondary outcomes, the time of surgery was evaluated. We also evaluated as subgroup analysis the transient and permanent paralysis in a group of patients with high and low risk of RLN injury. Results: Four randomized clinical trials involving 1.379 patients undergoing thyroidectomy using neuromonitoring or with identification only of the RLN, of which 2.605 was the total number of nerves at risk evaluated. Neuromonitoring reduced the risk of total (transient and permanent) vocal fold paralysis after thyroidectomies (RR 0.64, 95% CI 0.93 to 0.95, I 2 = 30%), as well as decreased the risk of transient paralysis (RR 0.60, 95% CI 0.38 to 0.95, I 2 = 10%), but did not decrease the risk of permanent paralysis (RR 0.84, 95% CI 0.36 to 1.93, I2 = 0%). The analysis of the mean time of surgery was conducted in two studies, however, the heterogeneity between the studies was greater than 75% and the meta-analysis was not appropriate to establish the difference in the mean time of surgery between the groups. As the analysis of subgroups, it was observed that neuromonitoring did not reduce the risk of transient paralysis (RR 0.61, 95% CI 0.28 to 1.31, I 2 = 0%) and neither the risk of permanent paralysis in low-risk thyroidectomies (RR 1.03, 95% CI 0.21 to 5.07, I2 not applicable). As it also did not reduce the risk of transient paralysis (RR 0.75, 95% CI 0.18 to 3.07, I2 = 71%) and permanent vocal fold paralysis in high-risk thyroidectomies (RR 0, 69, 95% CI 0.27 to 1.79, I 2 = 4%). Conclusions: This meta-analysis using only randomized clinical trials has demonstrated that recurrent laryngeal nerve neuromonitoring in thyroidectomies possibly slightly reduces the risk of transient vocal fold paralysis but probably makes little or no difference in the risk of permanent paralysis.

The clinical effectiveness of CBT-based self-help for symptoms of fatigue in multiple sclerosis

Gallen, Kirsty Louise January 2015 (has links)
Purpose: The aim of the systematic review was to address whether psychological interventions were able to reduce fatigue severity or the impact of fatigue in individuals with Multiple Sclerosis. The empirical study aimed to evaluate the effectiveness of a CBT based self-help workbook at reducing perceived impact of fatigue in a clinical sample of MS patients. Methods: A systematic search of the literature was carried out between the years 1980 and February 2015 to review whether psychological interventions were effective for fatigue management in Multiple Sclerosis. A randomised controlled trial examined the effectiveness of a CBT-based self-help workbook for the reduction of fatigue impact in MS. Participants were randomly allocated to one of three groups treatment as usual (TAU), pure self-help (PSH) or guided self-help (GSH). Results: Eleven studies were included in the systematic review, which indicated that CBT based interventions aiming to reduce fatigue or depression were most effective at reducing the severity of fatigue. Impact of fatigue can be reduced through mindfulness, CBT, motivational interviewing and to a lesser extent acceptance and commitment therapy. The empirical study did not find any significant differences between groups, however satisfaction with the workbook was high. Conclusions: The review suggests that there is a clear role for psychological interventions in fatigue management in MS, although further robust research into different therapeutic modalities is needed. From the empirical study it appears that the low level CBT-based intervention for fatigue in MS was not effective at reducing the perceived impact of fatigue. This study reflects an inclusive, clinical sample, recruited from a specialist rehabilitation unit, with high levels of multidisciplinary input which may have diluted any potential effect of the workbook. Objectives: The aim of the systematic review was to address whether psychological interventions are able to reduce fatigue severity or the impact of fatigue in individuals with Multiple Sclerosis Data sources: A search was conducted of: Psychinfo, Medline, Embase, CINAHL between 1980 and February 2015. Review methods: All studies were evaluated against a set of quality criteria by author (KG) with a proportion of studies being independently reviewed by author (DP) to ensure reliability of ratings. Results: Eleven studies were included in the review. CBT based interventions with a focus on fatigue management and depression appear to significantly reduce fatigue severity with medium to large effect. Significant reductions in fatigue impact can be found from mindfulness groups, motivational interviewing and CBT. Effect sizes for CBT interventions ranged from negligible to medium. For the mindfulness and motivational interviewing interventions effect sizes were not able to be calculated. The acceptance and commitment therapy intervention did not find a significant reduction in fatigue but found a medium effect for the intervention. Conclusions: There is a clear role for psychological interventions in the reduction of fatigue management but more high quality research needs to be carried out.

Telessaúde no apoio a médicos de atenção primária

Castro Filho, Eno Dias de January 2011 (has links)
Introdução: A estratégia Saúde da Família (SF) se apresenta como uma concretização em larga escala da reorganização de cuidados públicos em saúde baseados em Atenção Primária à Saúde (APS). Avaliada de modo amplamente favorável pelas populações servidas por ela, alcançou também impacto efetivo sobre seu perfil epidemiológico. Enfrenta ainda limitações e contradições. Seu desenlace depende, em importante medida, da continuidade de investimentos em seu aperfeiçoamento estrutural, na qualificação das pessoas que nela trabalham e no desenvolvimento do papel de coordenação do conjunto da rede de serviços do Sistema Único de Saúde. Uma das operações concebidas pelo governo brasileiro com foco na qualificação da SF é o Programa Telessaúde Brasil, com presença inicial em 900 unidades de SF em 9 estados brasileiros. Contribuir para uma avaliação deste Programa é o objetivo desta tese. Métodos: Uma revisão sistemática da literatura foi realizada para conhecer a experiência internacional com telessaúde para qualificação de médicos de APS. Para conhecer as repercussões do Programa Telessaúde Brasil junto a médicos da SF, desenvolveu-se um estudo descritivo sobre a experiência do núcleo Rio Grande do Sul (RS) do mesmo Programa entre 2007 e março de 2010. Resultados: De 8702 artigos filtrados na revisão sistemática, 63 foram incluídos por pertinência temática e estrutura metodológica. Apenas 5 Ensaios Clínicos Randomizados (ECRs), heterogêneos, faziam parte do conjunto, avaliando modo síncrono e assíncrono. Os ECRs apontaram para evitação significativa de exames e referências (exceto cirúrgicas), alta concordância diagnóstica e satisfação de médicos e pacientes. Redução de custos para os pacientes foi verificada no modo síncrono. Demais estudos foram amplamente favoráveis a intervenções de telessaúde para APS. No período considerado em relação ao núcleo RS, 226 médicos de 95 municípios foram integrados ao Programa. Desses, 161 médicos de 54 municípios solicitaram 673 teleconsultorias. Houve 68 médicos que avaliaram as respostas recebidas, perfazendo 294 consultorias avaliadas. Familiaridade prévia com informática prediz maior uso do serviço, mas permanência na SF prediz menor. Solução de dúvidas clínicas ou sobre o processo de trabalho em APS ocorrem na grande maioria dos casos. Os solicitantes têm alta satisfação com seu resultado. Uma referência (ou "encaminhamento") que ocorreria caso tais dúvidas não fossem solucionadas é evitada aproximadamente a cada 2 teleconsultorias. Conteúdo clínico predomina em 93% delas. Conclusões: O conhecimento disponível sobre a contribuição de telessaúde no suporte a médicos de APS carece de consolidação através de estudos que levem em conta os diferentes contextos. É fundamental saber não apenas se um tipo de intervenção é efetiva, mas quando, para quem e com quais recursos ela é efetiva. Além disso, é essencial disseminar a utilização de metodologia mais robusta nas pesquisas. As evidências até aqui coletadas sugerem que telessaúde seja uma intervenção útil para ampliar a resolutividade dos serviços de APS. Embora possam ser questionados em função das limitações já apontadas, os estudos de melhor qualidade até aqui realizados tendem a confirmar os resultados positivos do conjunto do material publicado. No RS, o objetivo de qualificar a prática médica em APS via telessaúde demonstrou-se viável, conforme foi avaliado pelos médicos que utilizaram este serviço junto ao núcleo RS e remeteram suas avaliações. No entanto, os desafios para que a utilização desse tipo de suporte seja mais ampla e intensa devem ser encarados com prioridade. Além disso, estudos em cenários mais permeáveis a comparação com grupo controle serão necessários para conclusões de maior solidez. / Context: The Family Health Strategy (FH) is presented as an achieving large-scale reorganization of public health care based on Primary Health Care (PHC). Evaluated so broadly supportive by the populations served by it, also reached an effective impact on its epidemiological profile. Still faces limitations and contradictions. Its outcome depends, in a significant extent, on the continued investment in its structural improvement, on the qualification of the people who works there and on development of a coordinating role in the whole network of the Unified Health System. One of the operations designed by brazilian government focused on qualification of FH is the Brazilian Telehealth Program. Methods: A systematic literature review was performed to meet the international experience with telehealth on qualifying primary care physicians. To assess the implementation of the Brazilian Telehealth Program to doctors of FH, it was developed an descriptive study on the experience of the Rio Grande do Sul's nucleus of this Program between 2007 and March 2010. Results: Of 8702 articles filtered in the systematic review, 63 were included in due to relevance and methodological structure. Only 5 Randomized Clinical Trials (RCTs) heterogeneous were part of this set, evaluating the synchronous and asynchronous modes. RCTs pointed to significant avoidance of tests and referrals (except surgicals), high diagnostic agreement and satisfaction of physicians and patients. Costs reduction for patients has been seen in synchronous mode. Further studies were broadly supportive to telehealth interventions for primary care. In the period considered, in relation to the RS nucleus, 226 doctors from 95 cities were integrated into the Program. Of these, 161 physicians in 54 municipalities requested 673 teleconsultants. Only 68 doctors assessed the responses, comprising 294 consultants evaluated. Prior familiarity to computer predicts greater use of the service, but remaining in the FH team predicts lower. Solving clinical doubts or work process troubles in PHC occur in the vast majority of cases. Applicants have high satisfaction with their result. Each referral that would occur if such question was not settled are avoided approximately every 2 teleconsultants. Clinical content predominates in 93% of them. Conclusions: The available knowledge about the contribution of telehealth in support of PHC physician needs consolidation through studies that take into account the different contexts. It is essential to know not only whether an intervention is effective, but when, to whom and with which resources it is effective. Moreover, it is essential to disseminate the use of more robust methodology in research. The evidence so far collected suggests that telehealth is an effective intervention for extend the resolution of PHC services. Although they can be questioned due to the limitations already mentioned, the better qualified studies made so far tend to confirm the positive results of all the published material. At Rio Grande do Sul (RS), the objective of qualifying medical practice in PHC via telehealth has been revealed feasible, according rated by doctors who used this service of the RS's nucleus and has sent their ratings. However, the challenges to using this type of support in wider and intense way must be addressed with priority. Furthermore, studies in scenarios more permeable to comparisons to control groups will be needed for more solid conclusions. / Telemedicina
