Factors predicting patient use of the emergency department: a retrospective cohort study

Background: Many studies have shown the tendency for people without a regular care provider or primary physician to make greater use of emergency departments. We sought to determine the effects of three aspects of care provided by primary physicians (physician specialty, continuity of care and comprehensiveness of care) on their patients’ use of the emergency department. Methods: Using provincial administrative databases, we created a cohort of 367 315 adults aged 18 years and older. Participants were residents of urban areas of Quebec. Affiliation with a primary physician, the specialty of this physician (i.e., family physician v. specialist), continuity of care (as measured using the Usual Provider Continuity index) and comprehensiveness of care (i.e., number of complete annual examinations) were measured among participants (n = 311 701) who had visited a physician three or more times during a two-year baseline period. We used multivariable negative binomial regression to investigate the relationships between measures of care and the number of visits to emergency departments during a 12-month follow-up period. Results: Among participants under 65 years of age, emergency department use was higher for those not affiliated than for those affiliated with a family physician (incidence rate ratio [IRR] 1.11, 95% confidence interval [CI] 1.05–1.16) or a specialist (IRR 1.10, 95% CI 1.04–1.17). Among patients aged 65 years and older, having a specialist primary physician, as opposed to a family physician, predicted increased use of the emergency department (IRR 1.13, 95% CI 1.09–1.17). Greater continuity of care with a family physician predicted less use of the emergency department only among participants who made 25 or more visits to a physician during the baseline period. Greater continuity of care with a specialist predicted less use of the emergency department overall, particularly among participants with intermediate numbers of multimorbidities and admissions to hospital. Greater comprehensiveness of care by family physicians predicted less use of the emergency department. Interpretation: Efforts to increase the proportion of adults affiliated with a family physician should target older adults, people who visit physicians more frequently and people with multiple comorbidities and admissions to hospital.

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

BackgroundThe 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.ObjectivesIn 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 goal of the present research project is to track the evolution 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.Methods/DesignThis 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.DiscussionThe results of this study will shed light on changes brought about in the organization of PHC and on factors associated with these changes.

Reforming healthcare systems on a locally integrated basis: is there a potential for increasing collaborations in primary healthcare?

BackgroundOver the past decade, in the province of Quebec, Canada, the government has initiated two consecutive reforms. These have created a new type of primary healthcare – family medicine groups (FMGs) – and have established 95 geographically defined local health networks (LHNs) across the province. A key goal of these reforms was to improve collaboration among healthcare organizations. The objective of the paper is to analyze the impact of these reforms on the development of collaborations among primary healthcare practices and between these organisations and hospitals both within and outside administrative boundaries of the local health networks.MethodsWe surveyed 297 primary healthcare practices in 23 LHNs in Quebec’s two most populated regions (Montreal & Monteregie) in 2005 and 2010. We characterized collaborations by measuring primary healthcare practices’ formal or informal arrangements among themselves or with hospitals for different activities. These collaborations were measured based on the percentage of clinics that identified at least one collaborative activity with another organization within or outside of their local health network. We created measures of collaboration for different types of primary healthcare practices: first- and second-generation FMGs, network clinics, local community services centres (CLSCs) and private medical clinics. We compared their situations in 2005 and in 2010 to observe their evolution.ResultsOur results showed different patterns of evolution in inter-organizational collaboration among different types of primary healthcare practices. The local health network reform appears to have had an impact on territorializing collaborations firstly by significantly reducing collaborations outside LHNs areas for all types of primary healthcare practices, including new type of primary healthcare and CLSCs, and secondly by improving collaborations among healthcare organizations within LHNs areas for all organizations. This is with the exception of private medical clinics, where collaborations decreased both outside and within LHNs.ConclusionHealth system reforms aimed at creating geographically based networks influenced primary healthcare practices’ both among themselves (horizontal collaborations) and with hospitals (vertical collaborations). There is evidence of increased collaborations within defined geographic areas, particularly among new type of primary healthcare.

Impact of Québec’s healthcare reforms on the organization of primary healthcare (PHC): a 2003-2010 follow-up

BackgroundHealthcare reforms initiated in the early 2000s in Québec involved the implementation of new modes of primary healthcare (PHC) delivery and the creation of Health and Social Services Centers (HSSCs) to support it. The objective of this article is to assess and explain the degree of PHC organizational change achieved following these reforms.MethodsWe conducted two surveys of PHC organizations, in 2005 and 2010, in two regions of the province of Québec, Canada. From the responses to these surveys, we derived a measure of organizational change based on an index of conformity to an ideal type (ICIT). One set of explanatory variables was contextual, related to coercive, normative and mimetic influences; the other consisted of organizational variables that measured receptivity towards new PHC models. Multilevel analyses were performed to examine the relationships between ICIT change in the post-reform period and the explanatory variables.ResultsPositive results were attained, as expressed by increase in the ICIT score in the post-reform period, mainly due to implementation of new types of PHC organizations (Family Medicine Groups and Network Clinics). Organizational receptivity was the main explanatory variable mediating the effect of coercive and mimetic influences. Normative influence was not a significant factor in explaining changes.ConclusionChanges were modest at the system level but important with regard to new forms of PHC organizations. The top-down decreed reform was a determining factor in initiating change whereas local coercive and normative influences did not play a major role. The exemplar role played by certain PHC organizations through mimetic influence was more important. Receptivity of individual organizations was both a necessary condition and a mediating factor in influencing change. This supports the view that a combination of top-down and bottom-up strategy is best suited for achieving substantial changes in PHC local organization.

Classification of emergency departments according to their services for community-dwelling seniors.

OBJECTIVES The goal was to develop a classification of emergency departments (EDs) based on their organization of services for seniors discharged to the community. METHODS This was a secondary analysis of data collected in a survey of key informants (chief physicians and head nurses) in EDs in Quebec on the organization of services for community-dwelling seniors discharged to the community. Organizational characteristics were classified a priori in the following three categories: 1) availability of human resources, 2) care processes, and 3) links to community services. A multifactorial analysis (MFA) was used to analyze the variables by category and globally, thus investigating not only the relationships between variables within each category, but also the relationships between different categories. The authors then proceeded to classify EDs using Wards method (hierarchical ascendant classification) applied to reduced data dimensions. RESULTS The sample consisted of 103 EDs. Analyses were carried out on data from the 68 (66%) of these EDs that supplied complete data. These 68 EDs did not differ in terms of their size or geographical location from the 35 other departments that supplied incomplete or no data. We identified three groups of EDs: most specialized (with regard to internal staff and care processes) and less community-oriented (n = 12), moderately specialized and less community-oriented (n = 28), and least specialized and more community-oriented (n = 28). CONCLUSIONS This classification of EDs with respect to their organization of services for community-dwelling seniors may be helpful to those planning services, to decision-makers, and to researchers. The three groups of EDs identified in this study represent three types of organizations with differing assets and limitations. The generalizability of these groups to other settings and the implications for patient outcomes should be investigated.

Outcomes of Community-dwelling Seniors Vary by Type of Emergency Department

OBJECTIVES The specific objectives were: 1) to compare the characteristics and 6-month outcomes of community-dwelling seniors in Quebec, Canada, who visited three different emergency department (ED) types and 2) to explore whether the differences in outcomes by ED type were seen among subgroups of seniors. METHODS The three types of ED were most specialized, less community-oriented (n = 12); moderately specialized, less community-oriented (n = 28); and least specialized, more community-oriented (n = 28). Administrative databases were used to create a cohort of 223,120 seniors who visited these 68 EDs during a 14-month period. Using a multilevel approach, the following patient characteristics were compared across ED types: sociodemographic (age, sex, urban vs. rural residence, proximity to ED); medical diagnoses and comorbidity burden; and utilization of hospital and physician services during the 16 months before the index ED visit. Cox regression analysis was used to model the relationships between ED type and two 6-month outcomes, adjusting for patient characteristics: 1) serious outcomes (death, acute or long term-care admission) among all individuals who made an index visit and 2) outpatient ED visits (without hospital admission) among those discharged either from the ED or hospital. Interactions between ED type and patient age, sex, urban-rural residence, and comorbidity burden were explored. RESULTS Compared to patients treated at the least specialized EDs, those at the most specialized EDs were more often urban-dwelling, resided outside the health service area of the ED, and had the highest disease burden and prior specialist utilization. Those treated at the moderately specialized EDs were intermediate between these two groups. During the 6 months after the ED visit, the rate of serious outcomes was higher and the rate of outpatient ED visits was lower for the most specialized compared to the least specialized EDs, even after adjustment for patient characteristics. The differences in these outcomes by ED type were attenuated among older patients and those with greater comorbidity. CONCLUSIONS More vulnerable community-dwelling seniors tend to be treated in more specialized EDs, which have worse linkages to community services. Improved linkages between more specialized EDs and the community (physicians, home care, and other services) and increased access to community services may improve outcomes in this population. Seniors treated at more specialized EDs were more likely to experience serious outcomes, but were less likely to make a return outpatient ED visit.

Constructing Taxonomies to Identify Distinctive Forms of Primary Healthcare Organizations

Background. Primary healthcare (PHC) renewal gives rise to important challenges for policy makers, managers, and researchers in most countries. Evaluating new emerging forms of organizations is therefore of prime importance in assessing the impact of these policies. This paper presents a set of methods related to the configurational approach and an organizational taxonomy derived from our analysis. Methods. In 2005, we carried out a study on PHC in two health and social services regions of Quebec that included urban, suburban, and rural areas. An organizational survey was conducted in 473 PHC practices. We used multidimensional nonparametric statistical methods, namely, multiple correspondence and principal component analyses, and an ascending hierarchical classification method to construct a taxonomy of organizations. Results. PHC organizations were classified into five distinct models: four professional and one community. Study findings indicate that the professional integrated coordination and the community model have great potential for organizational development since they are closest to the ideal type promoted by current reforms. Conclusion. Results showed that the configurational approach is useful to assess complex phenomena such as the organization of PHC. The analysis highlights the most promising organizational models. Our study enhances our understanding of organizational change in health services organizations.

Why Is Bigger Not Always Better in Primary Health Care Practices? The Role of Mediating Organizational Factors

Size of primary health care (PHC) practices is often used as a proxy for various organizational characteristics related to provision of care. The objective of this article is to identify some of these organizational characteristics and to determine the extent to which they mediate the relationship between size of PHC practice and patients’ experience of care, preventive services, and unmet needs. In 2010, we conducted population and organization surveys in 2 regions of the province of Quebec. We carried out multilevel linear and logistic regression analyses, adjusting for respondents’ individual characteristics. Size of PHC practice was associated with organizational characteristics and resources, patients’ experience of care, unmet needs, and preventive services. Overall, the larger the size of a practice, the higher the accessibility, but the lower the continuity. However, these associations faded away when organizational variables were introduced in the analysis model. This result supports the hypothesized mediating effect of organizational characteristics on relationships between practice size and patients’ experience of care, preventive services, and unmet needs. Our results indicate that size does not add much information to organizational characteristics. Using size as a proxy for organizational characteristics can even be misleading because its relationships with different outcomes are highly variable.

Mood disorders are highly prevalent but underdiagnosed among patients seeking bariatric surgery.

Dear editor, We have read with great interest the contribution of Leorides Severo-Duarte Guerra et al. [1]. The authors underlined the high lifetime prevalence of mood disorders and particularly bipolar disorders in patients seeking bariatric surgery in Brazil. It is worth noting that standardized evaluation enables to determine with more accuracy the prevalence of such disorders, but their research gives no information about the rates of underdiagnosed psychiatric disorders in such a population before this standardized evaluation. However, several studies have underlined that psychiatric disorders in community samples, in particular bipolar disorders, are frequently underdiagnosed and confused with major depressive disorders [2, 3]. This seems especially true in patients with obesity because major depressive episodes seem to be predictive of bipolar disorder in this specific population [4]. As a consequence, one hypothesis may be that a high proportion of psychiatric disorders is underdiagnosed in obese patients. We conducted a survey of 92 candidates seeking bariatric surgery at the Conception Hospital, Marseille (France) to determine psychiatric disorders prevalence using standardized evaluation of psychiatric comorbidity. Informed consent was obtained from all individual participants included in the study. When focusing on lifetime mood disorders prevalence, our results are similar to the authors. In our study, 31 patients (33 %) had bipolar disorder and 27 patients (29 %) had depressive disorder (Fig. 1). Interestingly, when focusing on previously diagnosed psychiatric disorders, before the standardized evaluation, we found that 48 % of patients suffering from bipolar disorder were previously diagnosed as suffering frommajor depressive disorder. Furthermore, 18 (60%) of the patients suffering from major depressive disorder were not considered to have any mood disorder. Such prevalent misdiagnoses may severely impact psychiatric and medical prognosis, in particular, due to inadequate or insufficient treatment. We therefore agree with the proposal of the authors of this article, suggesting the need for systematic screening for psychiatric comorbidities in this population. Our investigation provides further evidence of this necessity, but future studies are needed to better understand the reason for such differences in prevalence between daily practice and standardized clinical evaluation. Moreover, the impact of undiagnosed versus diagnosed psychiatric comorbidities on bariatric surgery efficacy remains to be further assessed. V. B. Da Silva (*) : J. M. Azorin : R.

Integrated Primary Care Teams (IPCT) pilot project in Quebec: a protocol paper

Introduction The overall aim of this project is to help develop knowledge about primary care delivery models likely to improve the accessibility, quality and efficiency of care. Operationally, this objective will be achieved through supporting and evaluating 8 primary care team pilot sites that rely on an expanded nursing role within a more intensive team-based, interdisciplinary setting. Methods and analysis The first research component is aimed at supporting the development and implementation of the pilot projects, and is divided into 2 parts. The first part is a logical analysis based on interpreting available scientific data to understand the causal processes by which the objectives of the intervention being studied may be achieved. The second part is a developmental evaluation to support teams in the field in a participatory manner and thereby learn from experience. Operationally, the developmental evaluation phase mainly involves semistructured interviews. The second component of the project design focuses on evaluating pilot project results and assessing their costs. This component is in turn made up of 2 parts. Part 1 is a pre-and-post survey of patients receiving the intervention care to analyse their care experience. In part 2, each patient enrolled in part 1 (around 4000 patients) will be matched with 2 patients followed within a traditional primary care model, so that a comparative analysis of the accessibility, quality and efficiency of the intervention can be performed. The cohorts formed in this way will be followed longitudinally for 4 years. Ethics and dissemination The project, as well as all consent forms and research tools, have been accepted by 2 health sciences research ethics committees. The procedures used will conform to best practices regarding the anonymity of patients.
