The breadth of primary care: a systematic literature review of its core dimensions

Background: Even though there is general agreement that primary care is the linchpin of effective health care delivery, to date no efforts have been made to systematically review the scientific evidence supporting this supposition. The aim of this study was to examine the breadth of primary care by identifying its core dimensions and to assess the evidence for their interrelations and their relevance to outcomes at (primary) health system level. Methods: A systematic review of the primary care literature was carried out, restricted to English language journals reporting original research or systematic reviews. Studies published between 2003 and July 2008 were searched in MEDLINE, Embase, Cochrane Library, CINAHL, King's Fund Database, IDEAS Database, and EconLit. Results: Eighty-five studies were identified. This review was able to provide insight in the complexity of primary care as a multidimensional system, by identifying ten core dimensions that constitute a primary care system. The structure of a primary care system consists of three dimensions: 1. governance; 2. economic conditions; and 3. workforce development. The primary care process is determined by four dimensions: 4. access; 5. continuity of care; 6. coordination of care; and 7. comprehensiveness of care. The outcome of a primary care system includes three dimensions: 8. quality of care; 9. efficiency care; and 10. equity in health. There is a considerable evidence base showing that primary care contributes through its dimensions to overall health system performance and health. Conclusions: A primary care system can be defined and approached as a multidimensional system contributing to overall health system performance and health

Influência de fatores estruturais e organizacionais no desempenho da atenção primária à saúde em Belo Horizonte, Minas Gerais, Brasil, na avaliação de gestores e enfermeiros

O objetivo do trabalho foi avaliar o desempenho da atenção primária à saúde (APS) em Belo Horizonte, Minas Gerais, Brasil, utilizando o questionário PCATool entre enfermeiros das equipes de saúde da família e gerentes. O escore total da APS foi 0,75 (bom); o primeiro contato (0,95), a longitudinalidade (0,83), a integralidade (0,83) e a coordenação (0,78) apresentaram melhor desempenho. O enfoque familiar, a orientação comunitária e o acesso receberam as piores pontuações (0,68, 0,56 e 0,45). Os fatores associados (p < 0,05) à melhor performance da APS foram: disponibilidade de equipamentos e outros insumos (RP ajustada = 1,57), formação dos profissionais em saúde da família (RP = 1,44), presença do médico por mais de 30 horas semanais (RP = 1,42) e quatro ou mais equipes por unidade básica de saúde (RP = 1,09). Os resultados revelaram a importância de fatores estruturais (sistemas logísticos adequados, formação da equipe em saúde da família) e organizacionais (médico em tempo integral, número de equipes da Estratégia Saúde da Família por unidades básicas de saúde) na performance da APS e na melhoria da qualidade

Barriers and facilitators to nurse-led advance care planning and palliative care practice change in primary healthcare: A qualitative study

Primary care settings are ideal for initiating advance care planning (ACP) conversations and assessing palliative and supportive care needs. However, time constraints and a lack of confidence to sensitively and efficiently initiate such discussions are noted barriers. The Advance Project implemented a national multicomponent training package to support Australian general practice nurses (GPNs) to work with GPs to initiate ACP and palliative care conversations in their practice. This paper reports on semistructured interviews conducted with 20 GPNs to explore barriers and facilitators to implementing the Advance Project model. Participants identified a range of factors that affected implementation, including lack of time, limited support from colleagues, lack of knowledge about systems and funding processes in general practice and a need for better alignment of the Advance Project resources and practices with general practice information management platforms. Barriers related to professional roles, particularly the lack of clarity and/or limitations in the scope of practice of GPNs, highlighted the importance of defining and supporting the roles that different primary health practice staff could play to support implementation of the model. The findings underline the need for complementary training in the Advance Project model for GPs and practice managers to enable a team-based approach to implementation

Inflammation and lithium: clues to mechanisms contributing to suicide-linked traits

Suicide is one of the leading causes of death in the United States, yet it remains difficult to understand the mechanistic provocations and to intervene therapeutically. Stress is recognized as a frequent precursor to suicide. Psychological stress is well established to cause activation of the inflammatory response, including causing neuroinflammation, an increase of inflammatory molecules in the central nervous system (CNS). Neuroinflammation is increasingly recognized as affecting many aspects of CNS functions and behaviors. In particular, much evidence demonstrates that inflammatory markers are elevated in traits that have been linked to suicidal behavior, including aggression, impulsivity and depression. Lithium is recognized as significantly reducing suicidal behavior, is anti-inflammatory and diminishes aggression, impulsivity and depression traits, each of which is associated with elevated inflammation. The anti-inflammatory effects of lithium result from its inhibition of glycogen synthase kinase-3 (GSK3). GSK3 has been demonstrated to strongly promote inflammation, aggressive behavior in rodents and depression-like behaviors in rodents, whereas regulation of impulsivity by GSK3 has not yet been investigated. Altogether, evidence is building supporting the hypothesis that stress activates GSK3, which in turn promotes inflammation, and that inflammation is linked to behaviors associated with suicide, including particularly aggression, impulsivity and depression. Further investigation of these links may provide a clearer understanding of the causes of suicidal behavior and provide leads for the development of effective preventative interventions, which may include inhibitors of GSK3
