Abstract
The aim of this article is to develop and assess a model for care coordination (CC). A novel hybrid approach of Decision-Making Trial and Evaluation Laboratory (DEMATEL) and partial least square structural equation modelling (PLS-SEM) has been used to assess the CC model. The study has been conducted in four phases: (a) literature review, (b) Delphi session, (c) development of CC model through DEMATEL and (d) validation of the model through PLS-SEM. The study involves perspectives of service providers as well as service receivers, for which data were collected from hospitals across India. The literature review and Delphi session helped in finalising the seven measures of CC. Identified measures of CC are: IT-enabled coordination, inter-professional teamwork and consistency, patient centredness, communication and information transfer, physical infrastructural facilities and requirements, delivery of quality care, and facilitating transitions and accountability. Patient-centredness was found to be the most important construct of CC. Delivery of quality care is the most influenced construct and is affected by all the other constructs. Based on the results, practitioners may develop an overarching strategy to deliver seamless care and better health outcomes. This understanding may help in designing processes which in turn would deliver health as a social good.
Introduction
With the evolving living conditions of people, expectations with regard to health care systems are also changing across the world. International bodies and national governments have started giving due consideration to the development of effective health care systems through policy reforms and effective regulation (Prakash, 2015). Governments need to realize that health is a social phenomenon and a hospital is a social institution which is affected by the socio-economic and political conditions of its environment (Wang, Wan, Clement, & Begun, 2001). Inadequate infrastructure, ineffective manpower and high load of patients are some of the major challenges of the Indian health care system (Bajpai, 2014). Achieving a high level of coordination becomes difficult, because hospitals are organized into specialized departments and this leads to strong interdependencies. In order to address this, health care systems aim to enhance patients’ outcome through care coordination (CC), which helps hospitals in improving their resource functioning. Coordination in the health care system is defined as a structural collaboration between participants who operate within distinct organizational structures using separate resources. It aims to be patient-centric, where the services are expected to be flexible so as to meet patients’ varying needs and are delivered through a minimum number of professionals following the norms of the therapeutic relationship (Rosenbach & Young, 2000). The focus of coordinated care is on orchestrating the efforts of doctors, nurses and administrative resources for enhancement in patient experience (Segal, Dunt, & Day, 2004; Solberg, 2011).
In order to meet the demands of coordination, hospitals have shifted towards standardized work processes, referred to as coordinated care pathways (Havens et al., 2010). Compared to care processes, care-coordinated pathways focus more on reorganization of care mechanisms. This raises the questions of who does what, when, where and how. Previous studies have measured CC in the specific environment of certain diseases, but their generalizability is limited (Crump et al., 2017; Young, Walsh, Butom, Solomon, & Shaw, 2011). Walsh et al. (2010) and Schultz and McDonald (2014) have developed conceptual models of CC. Moreover, much of the literature is built from studies conducted in developed economies. The existing literature attempts to conceptualize CC, but its measurement aspects have not been explored much. This article aims to explore the measurement aspects of CC. The research questions are:
RQ1. What are the relevant measures for implementing CC? RQ2. How these are measures interrelated with each other? RQ3. To what extent can these interrelationships be used as a basis for a generic model for coordinated care?
To address these research questions, the measures of CC have been identified and interrelationships between these constructs have been assessed. This assessment is through a novel hybrid research approach which combines Decision-Making Trial and Evaluation Laboratory (DEMATEL) and partial least square structural equation modelling (PLS-SEM). Findings reveal that CC is a polymorphous notion with various underlying concepts, aims and interventions in practice. Despite differences in patient groups, heterogeneous needs and the foci of providers, there are certain common components that are essential for the development of coordinated care services. Therefore, it is inferred that delivery of quality care and patient-centricity are central to CC. Subsequent sections of the article include the literature review, theoretical framework of the study, methodology used, data analysis, and results and discussion.
Review of Literature
CC has been recognized as an important aspect of high-quality health care delivery. There is a growing consensus that poor coordination, coupled with fragmented care, compromises the delivery of quality care and increases the chances of medication errors (Schultz, Pineda, Lonhart, Davies, & McDonald, 2013). The focus on CC originates from the increasing fragmentation and supply-oriented approach in health care, which leads to discontinuity, duplication and an absence of responsibility (Øvretveit, 2011; Yates, 2004). CC addresses these challenges and enhances quality of care and customer satisfaction. CC optimizes experiences of current patients and also improves social, psychological and economic outcomes (Kibbe, 2002; van Achterberg, Stevens, Crebolder, de Witt, & Philipsen, 1996).
CC is operationalized through mechanisms of information coordination, clinical management coordination and administrative coordination. Information coordination refers to the transfer and use of the patient’s clinical information, which is needed to coordinate activities between service providers (Øvretveit, 2011). Clinical management coordination refers to the provision of health care in a sequential and complementary manner. Administrative coordination refers to the coordination of patients’ access to different kinds of health services. Coordination is a concerted phenomenon where hospitals are configured through a single or a combination of care mechanisms. Elements of CC vary with the complexity of the disease (Gittell & Weiss, 2004; Michie, Miles, & Weinman, 2003). Issues of CC along with various units of care are elaborated in Table 1.
Description of Units of Care
The term ‘coordination’ refers to interventions intended to improve care, as well as to describe the systemic requirements such as assessment of needs, planning and review. Organizational studies literature defines coordination as a process for managing dependencies and the integration of interdependent tasks (Prectarius, 2016). Increasing professional specialization among health care professionals gives rise to fragmentation, which necessitates integration (Minkman, 2012). CC is identified as a key strategy that has the potential to improve the effectiveness and efficiency of the health care system. It refers to clinical aspects and focuses on real-time interactions between providers. This explicates the patients’ needs and ensures that these are communicated at the right time to the right provider (Harrison & Verhoef, 2002). Irrespective of the technology-intensive nature of modern health care delivery, it is the human service provider who uses the technology to provide the services. The effect of deficiency in or absence of health personnel is not restricted to a particular service delivery, but it rather impacts the complete coordination of a hospital (Wang et al., 2001). There are various activities which encompass the functioning of hospitals and they are structured along the systemic frame of input–process– output. This classification will help in assessing the level of coordination required for each activity. Various activities of CC along this frame are depicted in Table 2.
Activities of CC
It so emerges that there is no standard definition of CC. Its literature is in its nascent stage. Further research is needed to understand the effect of poor coordination on health care service delivery.
Methodology
The primary aim of this article is to develop and validate a model for CC. For this, a novel hybrid approach of Decision-Making Trial and Evaluation Laboratory (DEMATEL) and structural equation modelling (SEM) has been used. This hybrid approach has been highlighted in the literature (Meng, 2014; Wei, Huang, Tzeng, & Wu, 2010). This study has been carried in four phases:
Phase I—Literature Review: An extensive literature review has been conducted based on the articles published in Scopus, SCI (Science Citation Index) and SSCI (Social Sciences Citation Index) indexed journals. Insights derived from the scrutiny and analysis of such articles have been used to develop a theoretical framework of the study. Phase II—Delphi Interview: Fourteen measures of CC have been identified from the literature. In order to refine these measures, a regressive Delphi session was conducted with well-informed and well- cultivated doctors and academicians. This resulted in seven measures of IT-enabled coordination (C1), inter-professional teamwork and consistency (C2), patient-centredness (C3), communication and information transfer (C4), physical infrastructural facilities and requirements (C5), delivery of quality care (C6) and facilitating transitions and accountability (C7). Table 3 gives a brief description of each of these measures. Measures such as disease management, case management, in-house medication management, role of international affiliations, handling fragmentation along units of care, health care financing and health care governance were excluded. This Delphi session was conducted during November 2016. Phase III—Development of the Model: DEMATEL was used to identify interrelationships among measures of CC. Towards this, service providers were asked to indicate the direct influence that they believe each element exerts on each of the other elements on an integer scale ranging from 0 to 3. A higher score means that an element exerts a strong influence on the other element (Tzeng, Chinag, & Li, 2007). Data were collected from service providers such as doctors, nurses and administrators of public and private hospitals, from December 2016 to January 2017, using a snowball sampling approach. Perceptions of service providers were used, because they are the actors in the coordinated care pathways and would be able to judge the importance of these measures. Data were collected from 23 service providers. This sample size is adequate, as sample size for the use of DEMATEL is prescribed to be in the range 8–45 (Ranjan, Chatterjee, & Chakraborty, 2016; Sumrit & Anuntavoranich, 2013; Tzeng et al., 2007). The questionnaire used for data collection is depicted in Annexure 1. Data analysis was performed using software package MATLAB v13. Phase IV—Validation of the Model: The identified relationships were assessed using a PLS-SEM-based reflective model. The choice of the PLS-SEM was due to its ability to estimate a model with a large number of latent variables and indicators even with a small sample size (Sarstedt et al., 2016). PLS-SEM eliminates ambiguous incorrect solutions and ensures factor determinacy by directly estimating latent variable scores, factor identification by introducing flexible residual covariance structure and robust prediction in the context of small sample size, asymmetric distribution and interdependent observations (Hair, Hult, Ringle, & Sarstedt, 2017). PLS-SEM approach achieves high levels of statistical power in comparison to covariance-based SEM with relatively small and moderate samples and more complex models (Reinartz, Haenlein, & Henseler, 2009). Patients who received medical treatment from a hospital in the last one year were asked to indicate their perceptions about the provider organization. The perceptions of patients were considered as they are the end receivers of the service, and their experience would reveal the actual status of the service delivery. Data were collected on a five-point Likert scale from patients across India using a random sampling approach from January to July 2017. The questionnaire used for data collection is depicted in Annexure 2. Three hundred and fifty patients were approached and 137 valid questionnaires were received. The response rate was 39 per cent. This sample size is adequate as it is more than 10 times the maximum number of seven paths aiming at any construct in the outer model as well as in the inner model (Hair et al., 2017). The profile of these patient respondents is depicted in Table 4. Data analysis was performed using software package SmartPLS v3. Use of perceptions of service providers in conjunction with perceptions of patients enhances the quality of triangulation.

Data Analysis and Results
Identifying Interrelationships and Development of the Model
Average Matrix (A)
Calculation of the initial direct influence matrix (D): The initial direct influence matrix (D) can be obtained by normalizing the average matrix (A), in which all principal diagonal elements are equal to zero. Based on the matrix (D) the initial influence that an element exerts and receives from another is shown. The calculation of the matrix (D) is as follows, and the results are shown in Table 6.
Initial Direct Influence Matrix (D)
Derivation of the total relation matrix (T): The total relation matrix (T) is obtained after the direct relation matrix. This matrix elucidates the final structure of elements. The calculation of T matrix is as follows, and the results are highlighted in Table 7.
Total Relation Matrix (T)
Calculation of row and column sum and difference (r+c, r–c): In the total relation matrix, the sum of rows and the sum of columns are calculated and represented by r+c and r–c. These r+c and r–c values are used to interpret the results. The values for r+c represent the total effects both given and received by the corresponding indicators, whereas r–c values indicate the net contribution of the corresponding indicator on the whole system [51]. Table 8 depicts row and column sum and difference values.
r+c and r–c Values
Calculation of the threshold value (p): A threshold value (p) is set to filter the apparent effects denoted by the elements of the matrix (T), and it is necessary to explain the structure of the elements. If all the information from the matrix (T) converts to the impact–diagraph map, the map will be too complicated to show the necessary information for decision-making. The threshold value for this analysis was 1.2836. Only those elements, whose influence level in the matrix (T) were higher than the threshold value, can be chosen and converted into the impact–digraph map. Figure 1 depicts the impact–digraph map. The values on this map are plotted on the basis of r+c and r–c values and the relationships between them are established by the threshold values. The values on this map are plotted on the basis of r+c and r–c values and the relationships between them are established by the threshold values.
Based on the r+c values the seven measures in order of decreasing importance are as follows: patient-centredness (C3), delivery of quality care (C6), infrastructural facilities and requirements (C5), inter-professional teamwork and consistency (C2), communication and information transfer (C4), IT-enabled coordination (C1), facilitating transitions and accountability (C7). Measure C3 is the most important measure for CC with a value of 19.4643, while C7 is the least important measure with a value of 15.3015. In contrast, the importance of C1, C2, C3 and C4 are net causes, and C5, C6 and C7 are net effects based on r–c values. Figure 1 shows that measure C1 affects C3 and C6 and gets affected by C5 and C7, and the other measures are mutually influenced by each other.


Various researchers argue that coordination is an activity that involves many stakeholders and effective communication among them will enhance their accountability. Such communication relies on a robust physical infrastructure (Hilligoss, Song, & McAlearney, 2016; Young et al., 2011). The interrelationship among the constructs constitutes a model of CC. This model of CC is depicted in Figure 2.
Conceptual Model of CC and Research Hypotheses
Based on the derived model, the following hypotheses are proposed:
Relationships between Information Technology and CC
Information technology (IT) infrastructure enables CC and improves information, communication and dissemination across functions, and it results in an enhanced level of service delivery and customer satisfaction. Thus, there is a linkage between IT-enabled coordination and CC measures (Gittell & Weiss, 2004; Williams, Asi, Raffenaud, Bagwell, & Zeini, 2016). Formally stated:
H1 IT-enabled coordination positively influences delivery of quality care. H2 IT-enabled coordination positively influences communication and information transfer.
Relationships between Inter-professional Teamwork and CC
CC depends upon the way the service providers function. Teamwork among service providers enables an effective information transfer and enhances delivery of quality care to the patients (Gittell, 2009; Kibbe, 2002; Solberg, 2011). Thus, there is a linkage between inter-professional teamwork and quality of CC. Formally stated:
H3 Inter-professional teamwork and consistency positively influences delivery of quality care. H4 Inter-professional teamwork and consistency positively influences communication and information transfer.
Relationships between Patient Centricity and CC
The patient-centric approach is at the core of CC. Assessing patients’ needs and delivering quality care boosts coordinated care outcomes. Patient-centredness bolsters collaborative problem-solving and increases the satisfaction of patients as well as health professionals (Michie et al., 2003; Okhuysen & Bechky, 2009). Formally stated:
H5 Patient-centredness positively influences the delivery of quality care. H6 Patient-centredness positively influences inter- professional teamwork and consistency.
Relationship between Communication and Information Transfer and CC
CC is a patient-centred activity geared to assess and meet the needs of patients along the health care value chain. Communication and information sharing along the health care value chain enhances the delivery of care (Lillrank, 2012; McGuiness & Sibthorpe, 2003). Thus, there is a linkage between communication and information transfer and the delivery of quality care. Formally stated:
H7 Communication and information transfer positively influences the delivery of quality care.
Relationships between Physical Infrastructure and CC
A hospital’s state-of-the-art physical infrastructure supports IT enablement and aids in patient-centredness. Effective IT infrastructure enables sharing of information about patient needs, thereby resulting in the delivery of quality care (Wang et al., 2001; Yates, 2004). Formally stated:
H8 Physical infrastructure positively influences IT-enabled coordination. H9 Physical infrastructure positively influences the delivery of quality care. H10 Physical infrastructure positively influences patient-centredness.
Relationships between Accountability and CC
Facilitating transitions and accountability-related processes of CC meet a patient’s needs through effective information sharing and teamwork along the health care value chain. An accountability-linked service delivery system facilitates the delivery of quality care (Walsh et al., 2010, Young et al., 2011). Thus, there is a linkage between accountability and other CC measures. Formally stated:
H11 Facilitating transitions and accountability positively influence communication and information transfer. H12 Facilitating transitions and accountability positively influence IT-enabled coordination. H13 Facilitating transitions and accountability positively influence inter-professional teamwork and consistency.
Assessment of Measurement Model
Reliability was assessed by Cronbach’s alpha, which was greater than 0.8 for all the constructs. The overall composite reliability was 0.921; both results confirm the consistency and reliability of the data. Further, all the scales were examined for composite reliability (CR) as well as for convergent and discriminant validity. As presented in Table 1, the average variance extracted (AVE) values for all construct measures were higher than 0.5, suggesting adequate convergent validity. The CR values ranged from 0.916 to 0.958, higher than the suggested classical cut-off value of 0.7 (Nunnally & Bernstein, 1994) and reflect high internal consistency. Taken together, the analyses provide a robust support for convergent validity of the model. All AVE values in Table 9 (range 0.689– 0.785) exceeded the 0.5 cut-off limit suggested by Anderson and Gerbing (1988). Additionally, the diagonal elements in Table 9 (square root of latent variable AVEs) are higher than the respective construct correlations, suggesting discriminant validity. The Heterotrait–Monotrait (HTMT) values for the indicators have been calculated using the complete bootstrapping procedure of the SMARTPLS v3 software. All the values (ranging from 0.529 to 0.794) were below the acceptable range of 0.9, indicating the discriminant validity (Hair et al., 2017).
R2 and Q2 Values
The coefficient of determination (R2) measures the predictive accuracy of the constructs. These values represent the amount of variability in the endogenous constructs of C1, C2, C3, C4 and C6, which were 38.8 per cent, 57.6 per cent, 41.8 per cent, 51.1 per cent and 70.2 per cent, respectively; these were explained by the respective exogenous factors. These values are moderate and reflect predictive relevance. Values of R² in conjunction with Stone–Geisser’s Q² value (Geisser, 1975; Stone, 1974) were used to assess predictive relevance. The Q² value of latent variables is obtained by using the blindfolding technique (Hair et al., 2017) with an omission distance of 7 which yielded cross-validated redundancy Q2 values, all of which were above 0, thus indicating predictive relevance. The values are presented in Table 9.
Measurement Properties and Discriminant Validity
Multicollinearity
Before analysing the structural model, in addition to reliability and validity, the variance inflation factor (VIF) must be assessed to compute multicollinearity. Hair et al. (2017) recommend a cut-off value of 5.0 for multicollinearity. The VIF results for each construct were below the threshold value of 5.0 and indicate the absence of multicollinearity issues.
Assessment of Structural Relationships
The hypothesized relationships were tested using the PLS algorithm to generate the standardized path coefficients. As a follow-up analysis, a bootstrapping method was used to determine the significance of path coefficients. The results are summarized in Table 10.
Path Analysis
f2 Values
The effective size of each path in the model is assessed by f 2 values (Cohen, 1988). These f 2 values are depicted in Table 10. These values are in the range 0.177–0.425 and, as a norm, values above 0.15 show moderate effect and those above 0.3 indicate high effect.
Assessment of Structural Model
The model fit indices used were standardized root mean square residual (SRMR), normed fit index (NFI) and rms_theta. The chi-square value came out to be 1205.189 and 1268.268 for the saturated and estimated models, respectively. These indices are depicted in Table 11.
Model Fit Indices
CC Response Index (CCRI)
Importance-performance map analysis (IPMA) considers the performance of each construct on a target construct. This analysis extends the basic results of PLS-SEM by applying the total effects of the structural model (importance) and the average of latent variable scores (performance; Ringle & Sarsedt, 2016; Völckner, Sattler, Hennig-Thurau, & Ringle, 2010). Insights from IPMA may help service providers to prioritize their alternatives. Delivery of quality care was taken as target construct because it is the outcome of CC. IPMA results are depicted in Table 12. Physical infrastructure facilities and patient-centredness emerge to have the highest importance (0.56 and 0.47, respectively). In addition, inter-professional teamwork and consistency, along with communication and information transfer, have the highest performance (66.554 and 64.538, respectively).
Results of IPMA Analysis
Discussion
The aim of this article is to improve the understanding of measurement and implementation of coordinated care. Results demonstrate that effective coordination mechanism can be achieved when processes are specifically designed to respond to the needs of patients. Moreover, strong channels of communication as well as teamwork, which are facilitated by adequate infrastructure and technological support, help in delivering an enhanced level of care.
CC operates along a continuum varying from generic care to specialized care. It emerges that most of the studies in CC are disease-specific and represent specialized care. The disease-oriented approach to CC aims for high responsiveness and is more suitable for developed economies. The generic approach to care is more prevalent in emerging economies and aims to achieve high efficiency in their health systems. CC integrates activities along the value chain and nurtures efforts in meeting a patient’s needs (Walters & Jones, 2001). This helps in enhancing responsiveness, reducing unnecessary workload, improving resource planning and utilization, eliminating wasted time, strengthening synchronization, standardizing processes and enhancing patient satisfaction (van Achterberg et al., 1996).
CC is a process in which all components are orchestrated to enhance service delivery. CC requires a multi-dimensional approach in which each construct builds upon the other to create superior value (Rosenbach & Young, 2009). The constructs of infrastructure facilities and requirements, as also facilitating transitions and accountability, emerge as independent variables. Thus, CC is a process which is governed by the efforts of human resources. While tangible resources like infrastructure are important, it is the competence of professionals that drives the service processes (Michie et al., 2003). CC is needed to transform increasingly fragmented health care systems into patient-centric service delivery systems (Øvretveit, 2011). Ageing populations, increasing chronic diseases and variable health care settings necessitate coordination. Coordination takes time, which is typically not reimbursed. Infrastructure and resources are needed to respond to and meet the patient’s requirements.
Although managing transitions through CC in a health care system is in a nascent stage, this could be strengthened by infusing accountability-driven mechanisms. Accountability fosters patient-centric approaches and provides continuity in care-coordinated pathways. Best-in-class health care is patient-centred and outcome-oriented (Solberg, 2011). It aids in autonomous and informed decisions and should facilitate CC along bidirectional interaction between patients and providers. The process redesigns facilitate patients’ choices and streamline interaction points to improve outcomes and reduce costs (Okhuysen & Bechky, 2009).
Effective CC improves service delivery and outcomes of the health system. Various stakeholders such as policy makers aim for effective and efficient care, while doctors, nurses and staff aim to deliver high-quality and high-value care to the patients (Walsh et al., 2010). The proposed framework may be used to enhance system-wide performance. A hospital works on a set of activities, and when these activities are carried out in a well-coordinated system, the value proposition of service delivery is improved. Coordinated health care activities lead to an improved value chain in the system (Walter & Jones, 2001). A hospital may use value chain mapping to identify areas for improvement in quality or reduction in costs by delivering or connecting patients to the right services, so that they benefit from the entire set of activities required for effective care (Kibbe, 2002; Schultz et al., 2013). While private hospitals across the world are rapidly adopting these approaches, public hospitals are still struggling with poor infrastructure, lack of manpower and higher patient loads.
Meeting a patient’s need requires developing a culture of quality where individuals, departments, patient care teams and administrators are held accountable. Moving towards this kind of performance evaluation, measures such as procedures, clinical treatment protocols, critical pathways and statements of expected health care outcomes have been conceptualised. CC, through effective listening, communicating, information and knowledge sharing, clinical collaboration and enhanced patient experience, contribute to health care quality (Crump et al., 2017; Hilligoss et al., 2016). Hence, the aim of coordinated care is to facilitate the appropriate and efficient delivery of health care services within and across systems.
Concluding remarks
The aim of this article is to develop and validate a generic model for CC. Towards this, perceptions of service providers and receivers have been analysed. The service provider’s perceptions explicate that CC measures are interrelated with each other and their synchronization enhances the level of coordination. On the other hand, service receiver’s perceptions depict interrelationships between CC measures and may act as a tool to assess the levels of service delivery and customer satisfaction.
Results of DEMATEL-based analysis highlight that a patient-centric approach improves the CC pathways. Results of PLS-SEM analysis highlight that the delivery of care matters most to patients. The patients’ perspective suggests that CC pathways should be implemented to upgrade the service delivery channel of health care system. Implicitly, this framework is a measure of coordination at the system level. Organizational coordination is achieved at the system level and it needs the support of various arrangements, but its ultimate measure of success is how well it contributes to health outcomes. A potential limitation of this approach is loss of details about the experiences of coordination at the provider level. A second potential limitation is that patients may find it difficult to make an overall assessment.
