The Interaction of Public Health and Primary Care: Functional Roles and Organizational Models that Bridge Individual and Population Perspectives

Introduction: Public health and primary care are often conceived as two entities providing complementary services within the health system. This scoping review aims to better understand how the two sectors interact by identifying their shared functions, and by identifying organizational models that could facilitate the interaction between the two domains. Methodology: We conducted a review of published literature using PubMed and CINAHL journal indices. Our search yielded 179 articles. We reviewed abstracts and retained 55 relevant articles. We developed an extraction grid, based on a conceptual framework of functions of public health and primary care, in order to evaluate the relevance of selected articles, classify the information according to their functional connection, and identify interactions between them. Results: Our search identified various activities through which public health can contribute to more effective primary care, and functions usually performed by primary care that seemed to support a population health approach. Most authors identified screening and immunization as actions that are carried out in primary care, but that can benefit from the support of public health. Health promotion and lifestyle modification are also shared responsibilities that can take the form of collective or individual intervention. The surveillance and protection function of public health, which actually takes place in primary care, consists of case identification for prevention or early treatment. Primary care is the setting where patients present, whereas public health has the role of investigation and of providing advice to clinical settings. Planning and evaluation are also emerging activities that concern both public health and primary care. Many authors recognized that public health provides tools that enhance the planning of primary care activities and are more aligned with the actual needs of populations. Others noted that public health is able to assess primary care in light of the changing health of populations, which may lead to better results for groups of patients. Conclusion: One of the routes to a better understanding of how public health and primary care organizations can better interact is to identify the different contexts in which they collaborate successfully. Our scoping review of the scientific and gray literature identified various ways by which public health and primary care either reinforce each other through their respective functions, or increasingly act in a collaborative manner to increase population health and improve health systems performance

On the interaction of acetone with electrophilic metallocavitands having extended cavities

We report the synthesis and characterization of tantalum–boronate trimetallic clusters of general formula {[Cp*Ta]3(μ2-RB(O)2)3(μ2-OH)(μ2-O)2(μ3-OH)} (R= 4-(C6H5)(C6H4) (Ta3-4Ph), 4-(C6H5O)(C6H4) (Ta3-4OPh), 4-(C7H7O)(C6H4) (Ta3-4OBn), 4-(C8H5)(C6H4) (Ta3-4PhEt), and 4-(C12H7)(C6H4) (Ta3-4Napht)). All complexes have been characterized by NMR spectroscopy and X-ray diffraction. The trimetallic species feature a large Lewis acid type cavity allowing for substrate binding in both the solid and the liquid state using a unique electrostatic interaction and a hydrogen bond. ΔH° and ΔS° values for association of acetone with the complexes vary between −2.0 and −4.1 kcal·mol–1 and −3 and 2 cal·mol–1·K–1, respectively, showing weaker binding than smaller cavitands of the same type. The barrier for acetone exchange at equilibrium is similar for all complexes, and ΔH‡ values vary between 8.2 and 11.4 kcal·mol–1

Assessing the evolution of primary healthcare organizations and their performance (2005-2010) in two regions of Québec province: Montréal and Montérégie

<p>Abstract</p> <p>Background</p> <p>The Canadian healthcare system is currently experiencing important organizational transformations through the reform of primary healthcare (PHC). These reforms vary in scope but share a common feature of proposing the transformation of PHC organizations by implementing new models of PHC organization. These models vary in their performance with respect to client affiliation, utilization of services, experience of care and perceived outcomes of care.</p> <p>Objectives</p> <p>In early 2005 we conducted a study in the two most populous regions of Quebec province (Montreal and Montérégie) which assessed the association between prevailing models of primary healthcare (PHC) and population-level experience of care. The <b>goal </b>of the present research project is to track the <it>evolution </it>of PHC organizational models and their relative performance through the reform process (from 2005 until 2010) and to assess factors at the organizational and contextual levels that are associated with the transformation of PHC organizations and their performance.</p> <p>Methods/Design</p> <p>This study will consist of three interrelated surveys, hierarchically nested. The first survey is a population-based survey of randomly-selected adults from two populous regions in the province of Quebec. This survey will assess the current affiliation of people with PHC organizations, their level of utilization of healthcare services, attributes of their experience of care, reception of preventive and curative services and perception of unmet needs for care. The second survey is an organizational survey of PHC organizations assessing aspects related to their vision, organizational structure, level of resources, and clinical practice characteristics. This information will serve to develop a taxonomy of organizations using a mixed methods approach of factorial analysis and principal component analysis. The third survey is an assessment of the organizational context in which PHC organizations are evolving. The five year prospective period will serve as a natural experiment to assess contextual and organizational factors (in 2005) associated with migration of PHC organizational models into new forms or models (in 2010) and assess the impact of this evolution on the performance of PHC.</p> <p>Discussion</p> <p>The results of this study will shed light on changes brought about in the organization of PHC and on factors associated with these changes.</p

Acute bacterial prostatitis: heterogeneity in diagnostic criteria and management. Retrospective multicentric analysis of 371 patients diagnosed with acute prostatitis

<p>Abstract</p> <p>Background</p> <p>There is currently a lack of consensus for the diagnosis, investigations and treatments of acute bacterial prostatitis (AP).</p> <p>Methods</p> <p>The symptoms, investigations and treatments of 371 inpatients diagnosed with AP were analyzed through a retrospective study conducted in four departments – Urology (U), Infectious Diseases (ID), Internal Medicine (IM), Geriatrics (G) – of two French university hospitals.</p> <p>Results</p> <p>The cause of admission, symptoms, investigations and treatments depended markedly on the department of admission but not on the hospital. In U, patients commonly presented with a bladder outlet obstruction, they had a large imaging and functional check-up, and received alpha-blockers and anti-inflammatory drugs. In ID, patients were febrile and received longer and more appropriate antibiotic treatments. In G, patients presented with cognitive disorders and commonly had post-void urine volume measurements. In IM, patients presented with a wide range of symptoms, and had very diverse investigations and antibiotic regimen.</p> <p>Overall, a 3:1 ratio of community-acquired AP (CA-AP) to nosocomial AP (N-AP) was observed. Urine culture isolated mainly <it>E. coli </it>(58% of AP, 68% of CA-AP), with venereal agents constituting less than 1%. The probabilistic antibiotic treatments were similar for N-AP and CA-AP (58% bi-therapy; 63% fluoroquinolone-based regimen). For N-AP, these treatments were more likely to be inadequate (42% <it>vs. </it>8%, p < 0.001) and had a higher rate of bacteriological failure (48% <it>vs. </it>19%, p < 0.001).</p> <p>Clinical failure at follow-up was more common than bacteriological failure (75% versus 24%, p < 0.001). Patients older than 49 had more underlying urinary tract disorders and a higher rate of clinical failure (30% versus 10%, p < 0.0001).</p> <p>Conclusion</p> <p>This study highlights the difficulties encountered on a daily basis by the physicians regarding the diagnosis and management of acute prostatitis.</p

Evolution of Experience of Care of Patients with and without Chronic Diseases following a Québec Primary Healthcare Reform

Objectives. To assess the extent to which new primary healthcare (PHC) models implemented in two regions of Quebec have improved patient experience of care, unmet needs, and use of services for individuals with and without chronic diseases, compared with other forms of PHC practices. Methods. In 2005 and 2010, we carried out population and organization surveys. We divided PHC organizations into new model practices and other practices and followed the evolution over time of patient experience of care. Results. Patients with chronic diseases had better accessibility but worse continuity of care in the new model practices than in the other practices at both time periods. Through the reform, accessibility decreased evenly in both groups, but continuity and perceived outcomes improved more in the other practices. Use of primary care services decreased more in the new model practices. Among patients without chronic disease, accessibility decreased much less in the new models and responsiveness increased more. There was no significant change in ER attendance and hospitalization. Conclusion. The evolution of patient experience of care has been more favorable for patients without chronic diseases. These findings raise concerns about equity since the aim of the PHC reform was targeting in priority individuals with the greatest needs
