The interface between health sector reform and human resources in health.

The relationship between health sector reform and the human resources issues raised in that process has been highlighted in several studies. These studies have focused on how the new processes have modified the ways in which health workers interact with their workplace, but few of them have paid enough attention to the ways in which the workers have influenced the reforms.The impact of health sector reform has modified critical aspects of the health workforce, including labor conditions, degree of decentralization of management, required skills and the entire system of wages and incentives. Human resources in health, crucial as they are in implementing changes in the delivery system, have had their voice heard in many subtle and open ways - reacting to transformations, supporting, blocking and distorting the proposed ways of action.This work intends to review the evidence on how the individual or collective actions of human resources are shaping the reforms, by spotlighting the reform process, the workforce reactions and the factors determining successful human resources participation. It attempts to provide a more powerful way of predicting the effects and interactions in which different "technical designs" operate when they interact with the human resources they affect. The article describes the dialectic nature of the relationship between the objectives and strategies of the reforms and the objectives and strategies of those who must implement them.

Background

The interface between sector reform and human resources in health: a conceptual framework

The potential and actual impact of health sector reform on the health workforce has been highlighted in several studies [1-4]. Less work has been devoted to explore individual and collective reactions to reform attempts by workers. Understanding these reactions and their effects is important in assessing whether reforms can effectively reach their goals, since human resources factors can obstruct technically well-designed reforms and consequently deprive populations of their potential benefits.

Human resources are often considered just another type of input, like financial or physical resources [5], but this might prove wrong or at least too narrow a view. People working in health services are not exclusively "instruments" for delivering necessary health care [3,6]. They are strategic actors [7], who can act individually or collectively to modify the governments' projects, such as trying to impede budget cuts, which they present as a strategy to protect the quality of services, or blocking a more equal deployment of resources, which becomes an obstacle to achieving a more equitable access to care.

In this paper, we propose a framework to understand the interrelationships connecting health sector reform processes and human resources, focusing successively on:

• health care reform, its declared objectives, how it is implemented and its impacts on the health workforce

• human resources' reactions to reforms, at the individual and collective levels

• the intermediary factors that influence the effects of reform and the responses of the workforce.

The proposed framework is schematically represented in Fig. 1.

Figure 1

Health sector reform (HSR) and human resources (HR).

The analysis of the interrelationships between these factors provides a useful tool to predict the effects of different "technical designs" on the human resources they affect. This article intends to show the dialectic nature of the relationship between the objectives and strategies of reforms and the objectives and strategies of those who are expected to implement them. It tries to identify the gaps in knowledge about the determinants of workforce participation, whether in the form of collaboration or opposition to systemic changes.

The policy design implications of understanding these interactions can help to integrate human resources strategies into the health reform process and to construct a better institutional capacity for human resources development.

Discussion

Health sector reform: objectives, strategies and effects

Health care systems in most countries, rich and poor, have undergone reform processes stimulated by a growing concern about the weak correlation between the volume of resources expended and the outcomes in terms of health status. These reforms were usually embedded in a set of government reforms intended to improve the efficiency, equity of access and quality of public services in general [8], , . In many instances, however, these reforms actually focused on a single macroeconomic objective, that of reducing the government's operating costs and cutting budget deficits, without paying much attention to their other declared objectives. It is not the purpose of this article to critically look at the health sector reform movement, since there is an ample literature devoted to it [9-11].

Although each country's reform process has its own specificity, there are common trends, such as the pursuit of better outcomes in terms of quantity and quality of services using the same or fewer resources, which has become known as "getting more value for money." In the health sector, these objectives are commonly expressed in terms of improving equity of access to services, effectiveness of care, efficient utilization of resources, satisfaction of users, and sustainability. The emphasis varies, however, depending of the economic conditions and the political environment of the country. Here we will focus on the equity, efficiency and quality objectives, as they tend to be common to all health reform processes. We refer to these objectives as "declared objectives," recognizing that, in practice, reform processes can be driven by other motives and objectives, while still using the language of equity, efficiency and quality.

Efficiency

Efficiency is a relative concept: an intervention is more efficient than another in producing the same output. There is ample consensus in the distinction between "technical" efficiency and "allocative" efficiency: the former refers to productivity or to the best use of resources for extracting the maximum output from given inputs; the latter is concerned with choosing the interventions that produce the greatest benefits to health, at a given cost. Efficiency is a standard declared objective of reform in the public sector and in particular in the health sector. Many reform processes are led by the economic national authorities, and are focused on public budget reduction, on changing the relative weight of fixed and variable government expenditure, and on producing better services with the same (or fewer) resources. To achieve this, various approaches that directly affect human resources have been tried. The following tend to be the most common.

Budget-oriented reforms have tried to limit the central government expenditures by decentralizing social and health services at the local, provincial or municipal level to achieve efficiency gains and reduce deficits at the central level. Regardless of good intentions, the evidence indicates that the local levels were ill-prepared to manage the new responsibilities devolved to them [12], especially where this occurred in a context of decentralization without adequate budgets and appropriate tools [13]. This often led to increasing inequalities, while achieving little in terms of efficiency.

Another frequent approach has been to convert fixed (labor) expenditures in variable costs, by outsourcing services, particularly those of the non-clinical workforce (cleaning, laundry), but also the more technical services [14]. The following forms of contractual relationships have been identified [15]: Contracting out, where only private bids are allowed and where contracts may be agreed with or without a competitive process; Performance contracts, which are explicit agreements between the government and public sector managers; Internal markets, where there is complete separation between the roles of purchaser and provider within the public sector, and links through trading agreements or contracts. Competitive tendering (also known as market testing), where internal staff can bid for contracts in competition with private contractors; Internal contracting, where only internal bids are allowed.

The search for efficiency also included strategies to change the burden of labor costs in the financial equation. The importance of personnel expenditures (60 to 70 % of all sector expenditures) has made this item a favorite target. As a result, downsizing has been practiced in many countries, even though health services remain a labor-intensive product with little room for labor substitution. In addition, technological changes frequently generate demand for new specialized personnel. Another strategy particularly used in more costly settings, such as hospitals, has been re-engineering, centered in reviewing the organization of work, reallocating, and sometimes reducing, personnel to augment productivity [16].

Equity

Equity refers to fairness. The equitable distribution of health care among people of different levels of income is usually called vertical equity (care should be available as a function of need, not income), while distribution among people with the same health condition or need is called horizontal equity (equal need should entail equal treatment). The ideal of equity in health care has ethical and political foundations, well described by Donabedian in his classic typology of "egalitarian" and "libertarian" value choices [17].

Strategies aiming at improving equity in relation to needs (rather than to demands) require more systematic planning of health services, including the introduction of financial protection mechanisms, the targeting of specific needs and groups and redeployment of services, which is bound to have an impact on the distribution and the working conditions of the workforce.

Quality of services and users' satisfaction

Quality can be defined in many ways, but for the purpose of this paper we retain the following definition:

• Technical quality refers to the impact of the health services on the health conditions of a particular population. Technical quality is an important dimension of the providers' performance.

• Sociocultural quality measures the degree of acceptability of services and responsiveness to users' expectations.

The road towards improving quality is full of human resources challenges, in view of the complexity of the interface between users and providers. Constraints posed by budget cuts and the lack of congruence between the reforms' and the workers' values, translate in changes in performance levels and in users' satisfaction. Absenteeism rates, low morale of health personnel (especially in nursing), and higher rates of turnover, weaken the capacity to cope with the demands of quality care [18]

Health sector reform effects on HR

The expected objectives of the reforms translate into health system changes, which can have profound implications for the workforce configuration (as seen in Table 1), which in turn induce positive or negative responses from the workforce.

Table 1

Workforce implications of health sector reform

Efficiency/Outsourcing, privatization	Changes in contracts and working conditionsNew institutional arrangements, threat to the power of trade unions
Equity	Geographical and public/private redeploymentNew recruitment and retention mechanisms

(Adapted from Dussault & Dubois 2001 [29])

Strategies to better use scarce resources, as responses to a diagnosis of wasteful utilization associated with centralized bureaucracies, led many governments to transfer the management of health services to local authorities, for better control of spending and increased accountability. Where decentralization included transfer of human resources, local authorities had to play a new role as employers, often without the appropriate technical abilities or even the funding to do so.

In hospitals and other tertiary services, the objective of reducing or stopping the growth of fixed costs often led to substituting the internal provision of some services with external contracting. This measure resulted in changes in the number of permanent staff and flexible, therefore less predictable, contractual relationships with a growing part of their workforce.

Strategies designed to promote equity usually aim at the extension of coverage of underserved population groups, through making accessible an "essential package" of services, defined according to cost/benefit or cost/effectiveness criteria. This implies the availability of human resources in rural and impoverished areas, with primary health care skills and orientation, which in turn creates the need for new ways of recruiting and retaining of health professionals in areas and services where conditions are not perceived as attractive. Efforts to achieve greater technical and perceived quality usually take the form of upgrading the qualifications and trying to change the attitudes of key health providers, and of introducing new teamwork configurations, mainly through training [19,20]. Training activities are meant to align the workers' values and attitudes with the declared objectives of the reform process. They tend to be liked by reformers because they are visible to the public and seen positively – although not always for the right reasons – by workers, for instance when it means merely an opportunity to collect per diems, or to travel.

Effects of decentralization strategies

Changes in deployment and labor conditions following decentralization generally have two consequences on human resources:

• The new organizational structures mean that the role of employer, and consequently the union's organizations, are transferred to regional levels. The previous relationships must be reconfigured, with new actors who then must adapt their conduct to the new situation [21].

• The transfer of human resources functions without a comprehensive design of the financial transformations required may lead to deeper inequities, as local units are left to provide the services with locally collected resources [13].

Effects of outcontracting strategies

Outcontracting labor-intensive activities is affecting the legal framework of labor conditions in the civil service [22,23]. This can be perceived as a threat by the workforce executing the tasks targeted by the outcontracting process. While outcontracting to external bidders is likely to imply layoffs and modifications of the functions of involved workers, the creation of an internal market can lead to a process of cooperative work, without the radical changes in working conditions implied by external outcontracting [15]. In both cases, there is a potential conflict between the workers' interests and the efficiency goal, as competition offers a means to achieving "technical" efficiency while at the same time threatening employment stability.

Effects of equity oriented strategies

The need to deploy the workforce in line with the requirements of the burden of disease in a country or a region has deep human resources implications. In an ideal world, staffing would be guided by the needs of specific population groups. In the real world, geographical equity in the deployment of health human resources has always been a difficult task everywhere. Attempts in that direction easily induce personal and collective blocking strategies, which calls for a gradual, long-term approach [24,25].

Improvements in labor-intensive sectors, such as extending primary health care, require the active collaboration of providers, and their involvement and support to the process is a key factor of success. This is why governments generally end up making concessions to avoid their opposition to reforms and to make their implementation more feasible. But doing so might limit the expected impact of reform [26].

Effects of quality oriented strategies

Research on the influence of reforms targeting the organizational environment shows that health workers who have experienced job restructuring hold substantially more negative views about the impact of reforms on patient care than those who have not [27]. Staff reductions can have effects on quality indicators, such as those measured by the Outcomes Potentially Sensitive to Nursing (OPSN) index. A study in a large sample of hospitals in the United States found a relationship between the reduction of nursing staff and patient outcomes, in terms of an increased length of stay for four medical conditions [28]. These research results seem to confirm the influence of balanced staffing on the technical quality of services, but there is a paucity of evidence about its effects on users' satisfaction (perceived quality).

Workforce reactions to health sector reform

In labor-intensive industries such as health services, the importance of capital and technology is high, but never as much as the knowledge, attitudes and efforts developed by the persons in direct contact with the final users. This justifies a closer look at workers' reactions to changes resulting from reforms that can be regarded as changes in the rules of the employer-employee relationship [29].

Individual responses

This section discusses the reform-workforce interrelationships at the individual level, focusing on answers to changes in the incentives system, motivation factors and their consequences on the "psychological contract" between workers and the health care system.

Many studies in the service industry show how provider characteristics have the strongest influence on overall customer satisfaction. Service providers not only deliver and create the service but are often perceived as synonymous with service quality by the customer [30]. Services have been described as a "deed, act or performance," or as "encounters in time," rather than physical objects. The engagement of providers can help create a climate where autonomy, flexibility, and continuing learning add value to the quality of services by ensuring that they are continuously adapted to changing needs [31].

The economics literature defines human capital as the productive capabilities of people [32] and, within this definition, skills, experience and knowledge have economic value for organizations as factors contributing to productivity and to adaptability. Like other assets, human capital has value in the marketplace, but unlike other assets, the potential value of human capital can be fully realized only with the cooperation of the person. Therefore, all costs related to eliciting productive behaviors from employees, including those related to motivation, monitoring, and retention of personnel, are human capital investments from which returns can be derived. In human capital theory, contextual factors such as market conditions, unions, business strategies and technology draw their relevance from their effect on costs associated with alternative approaches to using human resources development to increase the value of the organization's human capital and the value of anticipated returns, such as productivity gains.

Responses to new incentives systems

Many reform interventions introduce some kind of linkage between pay and performance, through different arrangements in line with shifting from fixed to variable costs. Few of these schemes have been thoroughly evaluated [33], but the primary findings point to failure to achieve the expected results, and in many cases, the production of effects quite different from those foreseen by the planners of the incentives scheme [3,34].

The paradoxical results of new incentives systems that tried to modify the behavior of physicians show that physicians are capable of autonomous reactions, other than those predicted by economic theory. Even the most sophisticated mechanisms for paying physicians merely attenuate, and do not eliminate, overtreatment, undertreatment and other socially undesirable behaviors created by fee-for-service, capitation and mixed methods of payment. Moreover, sophistication in the design of payment incentives creates its own pathologies [35]. The limits of payment mechanisms explain the importance of non-price methods for motivating appropriate behavior, such as screening and selection, explicit prescription of desired performance, monitoring of compliance and inculcation of new norms and cultural expectations [36]

With technical non-medical employees, who are usually paid by salary and have poorer career prospects, the absence of more sophisticated incentives can lead some to opt out of the health sector. As it becomes perceived as conservative, not innovative and overly bureaucratic, the health care sector finds it more difficult to attract and retain good personnel, as is already the case in the area of information systems and e-business. While other parts of the economy are growing at a faster pace, health care's reluctance to incorporate new technology will force it to pay above-market wages, adding to costs that are already regarded as high, and broadening internal differences in an already unbalanced income distribution range [37].

Impact of new working conditions on motivation

A few studies have focused their work on the changes in attitudes and efforts of health workers in response to the exigencies imposed by the new rules created by the reform process [25,38,39]. The extent to which workers accept and share the proposed institutional changes seems to affect their motivation. Two interrelated psychological streams operate in the work motivation process:

• The "will do" component: the extent to which workers adopt organizational goals.

• The "can do" component: the extent to which workers effectively mobilize their personal resources to achieve joint goals [40].

Motivation can be enhanced or blocked, according to the following:

• The importance of goals' and values' congruence between workers and the organization.

• Efforts made to ensure that organizational goals are clear and that workers see the benefits of working towards these goals.

• Multiple channels influencing motivation: focusing solely on financial incentives is not likely to produce the desired results [39].

The congruence between organizational goals, system of incentives and reform values is especially important in the public health services, since it is perceived as a means to distribute valued public goods. Health professionals, who have internalized an ethos of public service, may resist the drive towards efficiency or cost-cutting measures, perceiving it as clashing with their own system of values.

Consequences on the psychological contract

The link between organizational objectives and personal motivation is the "psychological contract" between the individual and the organization. This notion describes a reciprocal relationship defined by the mutual expectations of the individual and the organization. The psychological contract is usually unwritten and unspoken, but nevertheless represents each party's expectations for the relationship's continued existence. For many individuals, the psychological contract includes an intrinsic belief that their work will give them a fulfillment through self-actualization, a sense of achievement, recognition, responsibility and the quality of personal relationships in the workplace [25].

New professional roles and new working conditions can break the psychological contract between health institutions and their workforce. For example, a survey on nurses' response to changes showed that those who had experienced reform-related mergers or restructuring held more negative perceptions of the climate for patient care than those who had not been through a merger, although the relationship was less strong than it was for restructuring. Nurses with a negative perception expressed an aspiration to have a greater voice in the organization and staffing of hospitals; they also showed a greater readiness to unionize [27].

Flexible arrangements, layoffs resulting from reduced budgets, and payment mechanisms tied to performance have replaced the ethos of hard work, security and permanence of work. But the attitude of individuals has also changed. In an environment where there is no long-term guarantee of employment, different employee attitudes emerge, characterized by greater emphasis on protecting self-interest [38] and greater readiness to use legal means for that purpose [41].

Collective responses

Some form of worker cooperation is needed to transform the institutional changes into expected results. Where there are strong unions and professional associations, these are key actors in the political economy of reforms almost by definition. A unionized workforce is more capable of maintaining wage levels, but not necessarily employment levels. A review of the situation in the United States in the 1980s showed that unionized employees have received wages estimated at 33% higher than nonunion employees. Unions were often credited with improving working conditions and safety [42].

The interests of the public service workers are usually expected not to clash with the interests of the citizens. Workers in social sectors are expected to abide by codes of ethics and rules that state their rights and duties, while maintaining the right to be represented by independent and free associations conducting collective bargaining on their behalf [43]. Retrenchment measures, which are a basic tenet of the standard public sector reform package, pose a direct challenge to the livelihood of public sector employees [2], which creates a tension with the expectations described above. It is therefore hardly surprising that the experience of the public sector reform model has been characterized by the decisive resistance by the employees, leading to delays and unplanned changes in implementation.

Professional associations' response

Health professionals, and in particular physicians, are rarely organized in the same unions that represent the other public service workers, but in associations following different models of organization and behavior [44]. The professionals and their associations are no longer assumed to automatically abide by an ethics of public service, as might have been considered before the 1970s. They are rather perceived as active stakeholders and lobbyists in pursuit of their own interest.

The classical statement that a profession attains and maintains its position by virtue of the protection and patronage of some elite segment of the society which has been persuaded that there is some special value in its work [45] probably still stands. But in the last decades, society has become more critical of the claims of professional groups that they are primarily client/public-oriented. Professionals nevertheless continue to exercise considerable influence on the regulation of the provision of health care, through the definition of standards of practice and by participating formally or through lobbying in the process of defining the legal and administrative framework of the health sector [46,47].

As a result, professional interests tend to dominate over the general welfare, creating protected labor markets, which can have negative consequences on efficiency and equity. An example is the blocking of substitution of labor by doctors refusing to delegate tasks to less extensively trained personnel, which is an obstacle to improving productivity and increasing access to services [48]. A free-market approach does not seem to correct these major imbalances, given the "market power" of the professional associations. A stronger regulatory capacity and a clear recognition of the differences between the values of the reform and the interests of the professionals may be a more fruitful approach.

Nonprofessional health workers' response

In a context of fiscal constraint, nonprofessional health workers often fear the effect of reforms on their income and work conditions, as well as on labor stability, tenure and promotion. Given the special character of health services, the cooperation of these workers is vital in improving their performance, thus making workers' organizations key actors in the political economy of reforms. The relatively high unionization rates of the public sector in Latin America and other regions, either in the form of labor unions or professional associations (when legal limitations forbid the former), facilitates the organization of collective action. Public health sector employees generally work in the formal sector and in non-tradable services. In combination with job stability clauses, these two factors reduce their exposure to competitive pressures (both domestic and international) and make them more resilient to the moderating effect of unemployment on wage militancy [26]. However, the pressures of the public services reforms have certainly had a downwards impact on unionization rates: It is not yet clear whether changes are due to general trends in unionization or to health sector reforms [43].

In Latin America, nearly all the countries have identified labor conflicts as a limiting factor of the capacity of the governments to reorganize the public health sector [49]. Even well-planned reforms, such as in Costa Rica, faced conflicts between the workers and the Social Security Fund Administration, when the union representatives challenged the new labor regulation – in terms of wages, selection, timetables and new roles of the health professionals – as unlawful and unconstitutional [23]. In Africa, relatively docile unions in Zambia were transformed into a powerful opposition to reforms when their conditions of service were threatened. The Philippines experienced similar unforeseen resistance to the devolution of health services to local governments in the mid 1990s [50].

In the United States, organized opposition of physicians and the labor movement contributed to the failure of reforms introducing managed care competition in health care in 1993. In the 1994 presidential political campaign in that country, large donor and political action committee (PAC) contributions tied to the health and insurance industry increased far faster than contributions by other industries. The American Medical Association's PAC was the leading contributor among health and insurance PACs, showing the concern and interest in influencing future administrations' health care policies [51-53].

An International Labour Organization (ILO) survey in 1998 described different collective reactions to the wave of reforms of the preceding decade. Table 2 gives country examples indicating that while physicians and nurses reacted more to systemic changes, other workers tended to react to layoffs and wage freezing.

While some of these reactions can be seen as contributing positively to the implementation of the changes, others clearly had negative effects, such as blocking the extension of primary care coverage (Israel), or jeopardizing the availability of care for the population by making trade-offs between budget reduction and maintenance of the level of medical fees (Quebec).

Intermediary factors influencing the effects of reforms and responses of HR

Here we have tried to identify some of the main interrelationships between the intentions of the reformers and the strategies of those expected to implement them. To some extent, all reforms and the resulting new configuration of services are reshaped, in one way or another, by the actions of workers involved in providing care or enforcing regulations. The question for policymakers is how to influence the direction of this reshaping, so that it is consistent with health objectives and health needs.

The literature points to a number of intermediary factors that can influence both the effects of interventions and the response of workforce:

• The importance given to the human resources factor cannot be disregarded in the strategic planning and implementation of the reform process, even when the timeframe of the reforms is tight and leaves little time for lengthy consultation of stakeholders [3,13,54]. In one way or another, the reactions of workers will influence the process and affect the plans.

• Getting workers involved in the design and implementation of the reform is important. However, as a substitute for participation, many projects train workers on how to follow new procedures, therefore rarely achieving the purpose of creating real commitment [19,20].

Participation of workers' representatives such as professional associations or unions is a necessary but not sufficient condition to successful reform design and implementation [29,55]. Clear definitions of efficiency, equity, and quality objectives are also crucial to reduce the risk that the participation process be diverted towards the self-interests of the workforce.

• A high degree of coherence between the institutional culture and values, the objectives of the reform instruments, and the tools and timetable of the implementation process facilitates the commitment of workers to the reform process [39,56]. Country experiences show how people who work in health services easily perceive the non-alignment between these components of the reforms [50].

• The complexities of promoting participation while preventing the conversion of the reform in a provider-led and interest-driven process call for a new role for health authorities, founded on a renewed view of public health organizations [20,55], and of critical activities such as human resources planning, information systems for policy, bottom-up policy design and personnel administration.

• The implementation process is as important as a good technical design [12,13]. Many well-planned transformations failed because the managerial or financial tools were not adapted to the proposed changes, creating labor turmoil and opposition from workers.

Figure 2 illustrates these reciprocal influences between human resources and health sector reform.

Figure 2

Factors mediating workforce-reform interrelationships.

The findings in Fig. 2 reveal a need to continue trying to fill the gaps of knowledge to improve the practice of human resources mobilization in reform processes. Further investigation is needed around unresolved issues such as:

• The influence of working conditions (stress, flexibility, outcontracting) on user's satisfaction (perceived quality), searching for evidence of quality diminution resulting from changing the working conditions in settings other than hospitals and nursing staff.

• How union and professional organizations' power is changing the level of employment in the health sector during the reform process.

• Characterization of the main intermediate factors that determine "paradoxical" responses to financial incentives aimed at changing doctors' practice.

• Collecting "best practices" in balancing workforce participation and attainment of objectives in real-world experiences, and finding the main environmental determinants in achieving this balance.

Implications for policy design

Two approaches or agendas in the development of human resources policies in countries undergoing health sector reform are superimposed [54,57]. The first one is what can be called the old agenda, which corresponds to issues generated by a model of stable and protected labor relations based on a lifetime career. The second approach or agenda is a new or flexible agenda, which responds to a new regulatory model characterized by the flexibility of labor and employment. The old agenda includes persistent problems that personnel administration has been unable to address. The new agenda refers primarily to situations and problems arising from the reforms.

Many countries, particularly in the developing world, have accumulated problems in solving the restraints posed by the old agenda. However, the reform processes have added new issues that became a burden too heavy to bear, decreasing their ability to cope with the overlapping challenges. The implementation of some "prescriptions" of the new agenda, such as decentralization or the introduction of new systems of incentives, has mobilized a great deal of the attention of human resources managers and policymakers, leaving less room to continue addressing previous shortcomings, such as strengthening health information system.

The transition to this new agenda, while keeping pace with the processes that the old one left unresolved, requires an integrated concept of the role of human resources factors in the health system as a whole. This concept should provide a clear vision of how the proposed configuration of the services will be affected by the human resources imbalances, and how to act to correct them. At the same time this integrated approach must be able to shape human resources policy, coherent with the values and health objectives of the reform, but with the flexibility to introduce the incentives and adjustments that the workforce requires to be continuously involved in the process.

The health authorities must build a human resources strategy into the reform process, including a consistent set of tools with organizational fit. Experience in other industries provides an insight into the impact of these strategies on overall performance, underlining the relationship between the different components of HR practices, the general attitudes of the firm and the global message that the firm transmits to its employees [56,58].

The human resources strategy is therefore integrated as a vital component of the policy design and planning, changing the role of the workforce specialist to a more political and strategic adviser, as part of the steering team of the reform. It also requires new capacities in the human resources units of the national health authorities [55], with information and monitoring roles in terms of developing a human resources information system. These new capacities should include: collecting and analyzing information about the reform process; a policy role in terms of developing an appropriate regulatory framework for health staff; and an advisory and guidance role in terms of providing technical assistance on workforce issues, and providing support for cultural changes.

These units should be able to:

• Build information systems to be able to measure the present and future human resource issues and trends.

• Gain trustworthiness to summon the participation of the representatives of the workforce towards clearly defined population health objectives.

• Be able to propose innovative and flexible ways of involving the workers in the new processes that should be coherent with the values and objectives of the health system.

• Maintain a bidirectional channel of communication between the policymakers and the representatives of those implementing the policies.

The construction of these new capacities is, at the same time, an urgent and long-term task that cannot be pressed, but that cannot be delayed.
