Many full-time Ugandan government health providers take on additional jobs – a phenomenon called dual practice. We describe the complex patterns that characterize the evolution of dual practice in Uganda, and the local management practices that emerged in response, in five government facilities. An in-depth understanding of dual practice can contribute to policy discussions on improving public sector performance.
A multiple case study design with embedded units of analysis was supplemented by interviews with policy stakeholders and a review of historical and policy documents. Five facility case studies captured the perspective of doctors, nurses, and health managers through semi-structured in-depth interviews. A causal loop diagram illustrated interactions and feedback between old and new actors, as well as emerging roles and relationships.
The causal loop diagram illustrated how feedback related to dual practice policy developed in Uganda. As opportunities for dual practice grew and the public health system declined over time, government providers increasingly coped through dual practice. Over time, government restrictions to dual practice triggered policy resistance and protest from government providers. Resulting feedback contributed to compromising the supply of government providers and, potentially, of service delivery outcomes. Informal government policies and restrictions replaced the formal restrictions identified in the early phases. In some instances, government health managers, particularly those in hospitals, developed their own practices to cope with dual practice and to maintain public sector performance. Management practices varied according to the health manager’s attitude towards dual practice and personal experience with dual practice. These practices were distinct in hospitals. Hospitals faced challenges managing internal dual practice opportunities, such as those created by externally-funded research projects based within the hospital. Private wings’ inefficiencies and strict fee schedule made them undesirable work locations for providers.
Dual practice prevails because public and private sector incentives, non-financial and financial, are complementary. Local management practices for dual practice have not been previously documented and provide learning opportunities to inform policy discussions. Understanding how dual practice evolves and how it is managed locally is essential for health workforce policy, planning, and performance discussions in Uganda and similar settings.
Dual practice, when health workers employed full time by the government take on additional jobs, is widespread in developing countries, particularly those with growing private sectors. Recent studies found that 29% of physicians in Cote d’Ivoire, 35% of physicians in Vietnam, 42% in Sri Lanka and 41% in Zimbabwe, , and as high as 80% in Indonesia and Bangladesh, held second jobs[1–5]. In some contexts, dual practice can be broader than private for-profit sector service delivery – including both research and NGO work. Researchers and policy-makers in developing countries display increasing interest in how dual practice affects the health system[6, 7].
Uganda is one of these countries. The country has a vibrant private health sector. Within this, the private not-for-profit health sector has, for decades, been acting as an extension of the public one, especially after the public health sector was mostly destroyed during the period of civil war and remains underfunded to date. Uganda’s private for-profit sector is large, fragmented, and disorganized, yet very little is known about it. Although there are growing discussions about public-private partnerships in health, dual practice seldom features on these agendas and data on this topic is scarce. In Uganda, in 2005, a nationally representative survey of private health facilities found that more than half (54%) of private sector doctors also declared being formally employed in the public sector. While estimates from public facilities do not exist, in general, health providers and policy-makers perceive that almost all government-employed health workers have dual practice. In addition, dual practice has been rising in importance on the policy agenda due to media reports of adverse health service delivery outcomes[10, 11], as well as suspected linkages to absenteeism and the wastage linked to it[12, 13]. A recent study aiming to establish policy-makers’ research priorities revealed that a principal concern was dual practice that was "reported to greatly affect the performance of the public sector. The dual [practice] of public health workers has implications on quality and management of health care delivery such as indiscipline, time loss and poor work ethics".
Despite these concerns, data on dual practice in Uganda and elsewhere is scarce. Although many types of health providers are believed to engage in dual practice, the available literature examines dual practice rather narrowly, generally only from the perspective of physicians. Furthermore, existing studies provide few answers to questions related to the policy and management of dual practice, beyond agreement that the effects of dual practice on the organization of the health system and service delivery can be either positive or negative, and that these effects, and related policy responses, are highly dependent on the local context[14–16]. For example, if well managed, dual practice may help prevent doctors from leaving the country by enabling them to supplement salaries without adversely affecting stock of doctors in the country. Conversely, if poorly managed, absenteeism and pilfering may negatively affect public sector standards of care and contribute to inefficiencies. The factors and interactions that drive these effects have not been explored extensively. Presumably, these factors depend on how dual practice has evolved and how it is managed in a particular health system.
Studying the dynamic aspects of dual practice and related interactions both within and outside the boundaries of a health system requires a departure from the linear, theoretical models found in the literature[2, 17–20]. A more appropriate model acknowledges the holistic, complex, and adaptive nature of health systems and their broader environment. Complex systems are composed of many interacting components that organize themselves in dynamic ways, are unpredictable in the long-term, and are able to learn from past experiences[21–23]. A research design acknowledging complex systems’ features, as well as potential interactions due to contextual factors, is ideal to guide the exploration of phenomena, such as dual practice, from multiple perspectives. It facilitates the exploration of complex system characteristics, such as feedback, emergence, and self-organization. In this paper, we explore how dual practice evolved in the Ugandan health system and how it is currently managed, in an urban environment – the city of Kampala, with an active private sector. Additionally, using systems approaches, we attempt to reflect on why dual practice persists and the factors underlying its current management. Understanding dual practice holistically in the Ugandan context provides a basis for exploring potential policy options. Gaining an in-depth understanding of the role of dual practice at various levels of the system can help policy-makers and health managers to strengthen management of dual practice and its consequences.
We use case studies of urban public health facilities to investigate the role of dual practice and the key patterns and interactions that it motivated in the health system. Review of policy documents, as well as qualitative interviews of policy stakeholders were used to supplement a qualitative survey of workers and their managers in the study facilities. In addition, during the data analysis phase, we developed a causal loop diagram to illustrate key factors and related feedback influencing dual practice in the current context. This paper presents only a sub-set of data that were collected as part of a sequential, exploratory mixed methods study.
Summary of selected cases
Health Center III*
Health Center IV
Policy stakeholders included purposefully selected individuals from professional councils, relevant government ministries, private not-for-profit medical bureaus, private sector hospital administration, and the local district health office. The main criteria guiding the sampling was the extent to which a stakeholder would know policies on dual practice either at the national level or within their organization, would have a stake in the development of a policy on dual practice, and present a unique perspective on dual practice in the Ugandan context.
Data collection instruments and field work
A review of policy documents was undertaken before the data collection, and as these documents became available. The main areas of interest were the existence and content of policies, actors, and events that played a role in the evolution of dual practice in Uganda, as far back in time as possible.
The interview guides contained questions about the evolution of dual practice in Uganda, providers’ motivation to engage in dual practice, advantages and disadvantages or challenges linked to dual practice, facility-level policies and management approaches, and potential policy recommendations. Interviews with policy stakeholders focused on policy-related questions, as well as on the evolution of dual practice in the health system. Data collection took place during July–August 2012. The interviews were conducted in English. Interviews were recorded, unless respondents preferred otherwise.
All of the recordings were transcribed and stored in Atlas.ti v. 7. A preliminary, exploratory coding structure was constructed based on initial readings of the transcripts and on the conceptual framework derived from a systems approach to health markets and theories related to systems thinking and health worker motivation[21–23, 26, 27]. Multiple rounds of coding focused on refining the scheme. During coding and analysis, memos were developed to capture changes in the coding structure, as well as emerging reflections.
Text query results from Atlas.ti were arranged in matrices for within and cross-case analyses, according to the methods suggested by Miles and Huberman. For each case, matrices were developed by theme (e.g., informal organizational policies), with focus on the embedded units of analysis (e.g., summarizing and contrasting the perspectives of health facility managers, doctors, and nurses). Cross-case theme analyses focused on exploring the differences and similarities between the five cases, specifically by health facility type. The policy stakeholder interviews were analyzed for emerging themes, along the same lines as the case studies. References to the analysis and any quotes are labeled according to respondent type, to maintain anonymity.
Causal loop diagram development
Although it was not an explicit goal of this study, interviews with policy-makers revealed that the role of dual practice and the government policy on dual practice changed over time, and that examining this progression might be useful for understanding the current policy situation. Based on discussions with policy-makers and case study respondents, as well as available historical accounts, we developed a causal loop diagram (CLD). The CLD illustrates the events, actors, and interactions – or the underlying mental model and system behavior – that fostered the emergence of dual practice policy responses over time in the Ugandan health system, facilitating the visualization of complex system patterns and characteristics, such as policy resistance, feedback, and adaptation[29, 30].
The CLD was developed using Vensim PLE Plus. It was challenging to recreate the history of dual practice, particularly in the distant past. An account of the medical profession in East Africa, which included details about the emergence and development of dual practice and the private sector from the perspective of physicians, helped to identify relevant early events from the 1960s and the 1970s. Recent events have been identified from the in-depth interviews conducted for this study and available documents. The CLD was refined through various iterations, to ensure that the relationships, interactions, and direction of feedback were most plausible.
The CLD uses standard notation: "a positive (+) arrow from variable A to variable B means that A adds to B, or, a change in A causes a change in B in the same direction; a negative (-) arrow from A to B means that A subtracts from B, or, a change in A causes a change in B in the opposite direction". Some of the relationships create feedback loops. These loops are reinforcing if the variables influence each other in the same direction. Loops are balancing if they influence each other in different directions. The thickness of the line denotes researcher’s emphasis on a relationship, for illustrative purposes. Dashed arrows highlight key, probable relationships identified through this study. The question mark (?) indicates an unknown relationship. This is not the recommended notation, as it is preferred to make explicit the "multiple causal pathways connecting the two variables". However, data currently do not exist to sufficiently tease out how dual practice affects service delivery. For example, while we know that dual practice can affect systems positively and negatively, whether and how much dual practice contributes to adverse service delivery outcomes is unknown.
Ethical approvals were obtained from the Institutional Review Board of the Johns Hopkins Bloomberg School of Public Health (IRB No. 4371), the Makerere University College of Health Sciences – School of Public Health Higher Degrees, Research, and Ethics Committee (IRB No. 11353), the Mulago Research Ethics Committee (Protocol no. 249), and the Uganda National Council for Science and Technology (Ref. No. SS 2883).

The remainder of this section first describes, in each phase, the feedback and interactions that emerged in relation to government policies on dual practice, as well as, more broadly, the development of a mixed health system in Uganda. It concludes by describing how dual practice is currently managed in the government facilities included in this study.
Phase 1: Dual practice policy before Uganda’s independence and through the 1960s
During this time, government restrictions on dual practice are formal – written and enforced: dual practice is allowed only after government hours. Some dual practice opportunities exist, however, demand is low due to high satisfaction with the government benefits. Few government providers chose to engage in dual practice, generally seeking the autonomy provided by private practice. No evidence was found that dual practice raised concerns about adverse health service delivery outcomes. Even as restrictions on dual practice became stronger after Uganda’s independence, the Ugandan government was able to provide government health workers with sufficient financial and non-financial incentives (e.g., satisfactory wages and the prestige of working in a government institution, respectively). One of the policy-stakeholder respondents confirms the general sentiment in this period:
"The assumption was, that what the government pays can cater for what you require in real life. […] in the 60’s, a medical officer, medical assistant, the nurse, was capable of catering for everything they required, the basics of life [with the government salary alone]. And they were held with high esteem, they were very ethical. I mean a medical officer would walk with his head high." – Ministry of Health policy stakeholder
Phase 2: Dual practice policy in the 1970s and 1980s
During this period, instability affects the health workforce in multiple ways: through reduced infrastructure and government budgets, as well as through persecution of health providers for political reasons. These country-level hardships are intensified by the broader global recession. The multiple crises cripple the government health system, and mark the beginning of several decades of low government salaries. While the job security and prestige related to government service are still important, the government financial incentives are no longer sufficient for providers who remain in the system. Many government providers resign at this time, or leave the country. Increasingly, government providers who remain in the system seek additional income through dual practice. The same policy stakeholder explained:
During the 1980s, the global debt crisis and the subsequent structural adjustment program fuelled the development of the private sector, while, at the same time, constraining government budgets. In this context, the financial benefits of working in private practice significantly exceeded those of the public sector, and motivated government providers to engage in dual practice. Government restrictions remain formal, but weak, at this time. Based on the available information, we propose that during this eventful and tumultuous period, dual practice and the incentives related to practicing in the private sector complement incentives for government service. Moreover, restrictions on dual practice without any further measures to address the government health system contribute to a decrease in the number of government providers. The dashed lines in Figure 2 highlight these proposed influences.
Phase 3: Dual practice policy from the 1990s to the present
Dual practice opportunities grow quickly in a context of rapid private sector growth, as well as of increasing donor-funded research and NGO projects, generally housed within public facilities. Due to an ever constrained budget and growing population demand, the government health system cannot offer providers an alternative to dual practice. Private practice during this period promises significant financial incentives, particularly in contrast to low government salaries, but lacks the job security and prestige that are still associated with government practice. The increasing population demand, as well as the significant earnings possible through private practice, make dual practice a frequent coping mechanism for government providers. In the absence of formal rules to manage dual practice, health facility managers develop their own formal and informal practices for mitigating detrimental effects of dual practice, such as absenteeism, while retaining the government health workforce, despite low salaries and poor infrastructure.
The absence of a formal policy on dual practice was confirmed by interview participants and also by our review of Ministry of Health and Ministry of Public Service policy documents. As our respondents illustrate below, current government restrictions are informal – unwritten, not enforced, and based on expectations of provider behavior in the public sector.
"I don’t think there is a clear policy saying that there is no dual practice […] we are expected NOT to do it […]. [Health workers] know what’s supposed to be the normal, but are kind of forced to do it, as I’ve said, to improve a bit on their earnings. […] We don’t come out to fight it. I can’t tell someone please don’t go the other end, because there’s a reason that is pulling this person to go, and I have no control over that. All I can do is to make sure enforcing that this person is here with me at the right time, for 7 or 8 hours. So we can’t influence what happens beyond that […] I cannot influence the earnings. […] The person has the needs, and I can’t satisfy the needs in any other way […] I can’t provide alternatives." – Government official 1
"A lot of policies are implemented while they are just known by the policy-makers but they are not written down. So, we know about dual practice and the policy is that […] it should be left as it is. That people can be allowed to do dual practice. […] It is not written. It’s not written at all, but they should not take too much of public time to do it. […] Unfortunately, there is no mechanism to enforce how much public time people are going to take because […] a lot of things that have gone wrong, including this dual practice, have gone wrong because of poor regulatory systems." – Government official 2
Interviews with policy stakeholders revealed that the government initiated periodic attempts to formalize government restrictions on dual practice, motivated by suspicion around dual practice due to media coverage of adverse health outcomes and poor public sector performance. Additionally, restriction attempts are triggered in the context of budget discussions, media reports about ghost workers, and increased concerns about quality of care in both public and private sectors as indicated by adverse health service delivery outcomes linked to absenteeism, pilfering of drugs, and patient deaths in the private sector from suspected malpractice.Escalating policy discussions around formalizing restrictions on dual practice are often met with provider protests, triggering the feedback displayed in Figure 3 and the government goes back to "keeping quiet", in this case meaning informal restrictions. A couple of the policy stakeholders provides examples of such events, which also illustrate that the government increasingly recognizes the role of dual practice in the system, particularly in the absence of changing government pay.
~2005–2007 : "The [high level official] gave a directive that it should stop. […] He said: ‘Officer, we are going to work out the methodology of implementing it […] But we shall not do it broadly across the country, we shall test it in some hospitals.’ So we came [to one of the hospitals], and communicated what the [high level official] had done, and said, these people [at this hospital] said: ‘We hear you loud and clear, but let’s agree if I cannot take that prescription, am I free to leave the government job? So that I can go to the other side [meaning private practice]? […] we either stay or go? Is that what you’re trying to communicate to us?’ We said: ‘Yes’. Within two days […] the [hospital] director came rushing to the headquarters to say: ‘Guys, stop talking about dual practice because everybody is winding up to go.’ So, the [government official] went back and told the [high level official]: ‘We tried to test it in [a hospital] and all the consultants are not bothered - they want to leave [this hospital].’ - and dual practice has gone on." – Ministry of Health policy stakeholder 1
In response to the cycles of uncertainty related to informal government restrictions to dual practice, as well as to coping with potential negative consequences of dual practice on public sector performance, we found that local, facility-level and department-level management practices can develop in government facilities. Facility management practices arise in response to increasing number of government providers with dual practice and aim to reduce any adverse service delivery outcomes in the public sector. As long as dual practice remains an incentive for providers to remain in government service (and sufficient resources to incentivize providers otherwise do not exist), these facility management practices could potentially weaken any policy restrictions to dual practice and any related negative effects on the government workforce.

Effect on the supply of government providers
Dual practice allowed after government duties completed
Associated misunderstandings potentially create feedback that decreases the supply of government providers. Providers interviewed had a different interpretation of the in-charge’s version of "completeness," and reported leaving government work early. The misunderstandings associated with this approach were perceived to result in absenteeism
Motivate providers to perform at their public sector job (e.g., supportive supervision; tea, purchased in health manager’s personal funds); non-interference with health workers lives outside government duties
Potentially promotes desirable feedback, by creating conditions to improve public sector performance and retain government providers
Discourage dual practice; emphasize priority for government duties and high public sector performance
Potentially promotes undesirable feedback by reducing the number of government providers; alternatively threats of disciplinary action could support improved performance in public sector
Priority for government duties; non-interference with time outside government duties
Potentially does not affect government supply of doctors, but creates tensions among staff
Although the Case D – the smaller hospital’s leadership had a positive attitude towards dual practice, they did not report a specific management strategy, except non-interference. Doctors reported to cope with dual practice through individual negotiations among their colleagues; however, this was not without pitfalls, as nurses were perceived to compensate for the absence of doctors. Furthermore, doctors appeared to have difficulty responding to emergencies, given that they juggled two or sometimes more places of work
Yes, in the context of flexible scheduling; N/A for other policies and practices
Potentially effective at reducing the number of nurses working two full time jobs. According to respondents, also improved attendance among nurses. Probably no effect on those with part-time dual practice
Policy preventing nurses to sign up for only night duties (which typically means they have a full-time day job)
A memorandum of understanding with externally funded research projects, to stop the active recruitment of government staff to fill full-time positions on projects
Effective at reducing active recruitment by research and NGO projects, therefore reducing internal dual practice opportunities. According to respondents, also improved attendance among nurses
Ineffective – mild effect on government providers, but has potential if more efficient.
Sustains retention among government providers, particularly specialists. Flexible scheduling creates friction among non-physicians
In one case, a health manager fostered a culture of flexible scheduling, i.e., all senior doctors get one day or certain afternoons to dedicate to their other activities, whether research or dual practice, in exchange for reporting to duty on other days. According to the unit’s manager:
"We tried to create a bit of flexibility and say, ok, all of us must be on station in the morning, and let’s take turns to cover the evening. And may be trying to bring the evening time a bit forward to, to allow people to earn some extra earning. […] When I see the outputs, then I don’t complain. Yes, and sometimes they come and start early, before 8 o’clock and if someone is here by 7 and even comes back on the weekend to clear if there is any backlog, I think, really, I can only say thank you because I can’t pay them more than they earn." – Case E, Health manager
This particular arrangement was not only facilitated by the fact that the unit manager was understanding of the reasons why providers would engage in dual practice and had an output-oriented supervision style, but also by the fact that the majority of doctors working in this unit worked in the same private health facility, which was close to their government location.
Within the larger facilities, formal policies included, for example, having a private wing, where doctors and nurses could see and get paid for private patients under the auspices of the government facility, or limiting nurses’ night duties so as to deter them from taking up full-time dual practice during the day.
Most of the health managers interviewed had a generally favorable attitude towards dual practice, not discouraging it within their facility. Their attitude stemmed from their own personal experiences where, in the past, they also had no choice but to take on additional jobs to compensate for government sector shortcomings. It also stemmed from broader frustration at not being able to enforce attendance policies and not having the necessary tools to adequately monitor health workers (an exception was the health manager for Case C, who expressed high confidence in public accountability). The principal tool available to managers for holding health workers accountable were attendance registers, which could be easily falsified. In this context, dual practice was generally tolerated within government facilities. Health managers emphasized the need to prioritize the completion of government duties and, to the extent possible, tried to introduce incentives for improved performance in the public sector.
"I don’t stop anybody from doing that. What […] I tell them is that: priority is a core job and your core job is the public service. Once you do my work well, then I don’t mind about what you do next." – Case D, Nurse/Health Manager
These management approaches, generally lenient with respect to dual practice, seemed to mitigate providers’ exit from the government health workforce. Additionally, they also seemed to tackle broader issues of provider performance, such as absenteeism. In Case B, providers reported being able to manage their two jobs without conflict. One of the providers reported seeing dual practice as a privilege: "if you want to reward yourself by doing an extra job, you have to make sure we [in the government sector] are covered" (Case B, doctor). Nevertheless, because of the broader health system issues, where managers lack tools to properly enforce policies in general, approaches to manage dual practice also had shortfalls. For example, in Case C, the in-charge reported that providers who were found with multiple jobs (often caught in the private facilities), were asked to quit them in favor of government service. While this manager reported confidence in this approach, the other respondents from the facility reported that almost everyone in the facility engaged in dual practice, but this was not discussed with the manager. Some of these approaches also created tensions among staff. The flexible scheduling mentioned earlier was not available to non-physicians and therefore friction arose from time to time among work teams. The private wing is one of the dual practice policy interventions listed in the literature, however, in the study context, it was perceived to be inefficient, and the infrastructure only marginally better than the rest of the facility.
This paper is one of the few contributing empirical evidence on dual practice policy and management practices in Uganda and low- and middle-income countries, more broadly. It illustrates how dual practice policies changed over time in the Ugandan system and how this phenomenon is currently managed within a sample of government facilities. It also attempts to use the existing data to reflect on and to explain why dual practice persists and the current approaches that have developed in the study context.
Due to a series of health and non-health sector events, feedback, and learning, dual practice has become an informal, yet integral component of a government health workers’ incentive package. This package has also evolved over time to one where job security and prestige remain important, but no longer sufficient due to some of the lowest salaries in the region, poor system infrastructure, and increasing patient loads. In a situation where the government cannot offer financial or non-financial alternatives to substitute dual practice (i.e., improve the incentives for sole public practice), the official policy for dual practice shifted from formal restrictions to one based on informal expectations. Any attempts to formalize restrictions is met with unintended consequences due to policy resistance and emerging feedback, threatening the stability of government health workforce more broadly.
Our data confirmed the existence of self-organization through local, facility-level management practice, which allow health managers and providers to cope with working in both the public and private sectors. The purpose of these practices was not necessarily to curb dual practice, but to maintain performance of the public sector by ensuring the presence of providers and, at the same time, to achieve an optimum balance between government workers’ public and private activities and needs. Some of these management practices were easy to identify and describe, e.g., the ones guided by a health manager, as in the example of the hospital department. Other management practices, based on individual negotiations, presumably depended on internal provider networks, whose development, and also decline, could not be captured through our study methods. Most frequently, health managers found opportunities to intervene as common symptoms of dual practice that threaten public sector performance, such as absenteeism, triggered concerns. These management practices could potentially minimize destabilizing effects occasionally arising from the policy feedback and resistance.
Our exploration revealed two issues that are relevant beyond the issue of dual practice policy and management and perhaps also beyond the Ugandan context. First of all, public sector performance management emerged as an area with significant shortfalls. In the absence of tools and support for rewarding good performance and punishing poor performance, the tacit, indirect approach to managing dual practice does not sufficiently empower health managers to supervise and enforce boundaries for government employees, who must fulfill their duties in both the public and private sectors. Also, because the nature of dual practice differs among nurses, general practitioners, and specialists, cadre-specific management approaches and tools might be appropriate.
Second, the nature of the Ugandan health system, and that of many sub-Saharan African countries, is very different than it was immediately after independence. Initially designed around the public sector, the private sector and particularly the private for-profit components, have been treated with suspicion and not integrated within a broader vision for the health system. Presently, the pluralist health systems that dominate low- and middle-income countries cannot be ignored. As a majority of the population, including the poor, relies on the private for-profit sector, increasing government stewardship is necessary to maintain the highest standards of service delivery. In this context, providers engaged in dual practice could serve as a channel for reaching the private for-profit sector and the synergies between government practice and private for-profit practice must be recognized.
How dual practice actually affects the health system and service delivery remains one of the key unknowns. While the literature and study respondents acknowledged both positive and negative effects of dual practice, in most low- and middle-income contexts, Uganda included, actual effects on the health system are unknown. Furthermore, issues such as shortfalls in quality of care, absenteeism, and efficiency gaps in public spending have broader root causes and can only partly be attributed to dual practice. A better understanding of the dual practice effects on providers, health facilities, and the broad health system would help governments to better calibrate their policy approach and to explore options for reaching a better balance between public and private sector spheres in health care.
Strengths and limitations
This study represents one of the few exploring dual practice holistically, from multiple perspectives (doctors, nurses, managers, policy stakeholders), and by applying systems thinking tools, such as the CLD. Only a few examples of CLDs exist in health research[36–39]. The researchers established credibility and confirmability of the findings by triangulating the data from the interviews across multiple types of providers, and, where possible, through the document and policy review.
The conclusions are constrained by several limitations. Much of the early history of dual practice in Uganda relies on a single source and it was not possible to verify the events or written government documents we mention. Because the case studies were based in a large urban center, generalizations to rural Uganda, where the opportunities for private practice are substantially different, are not possible. We could not explore dual practice in private not-for-profit or for-profit facilities or include additional cadres believed to engage in dual practice (e.g., clinical officers). The large hospital was much more complex than the other cases included in our study, and perhaps deserved to be studied in greater depth. Although the information presented in the CLD was triangulated across all available data sources, it could not be validated with study respondents as it was developed after the data collection ended.
Future research into how dual practice is managed by public facilities and how private for-profit facilities incentivize and contract with their providers, would be helpful. More in-depth studies looking at dual practice from the perspective of other cadres, such as clinical officers, or of rural practitioners could provide additional insights into this phenomenon. The facility-level management mechanisms described here could inspire formal policies aimed at minimizing the negative consequences of dual practice, while helping to seize opportunities for public-private sector synergies. The effects of dual practice on service delivery outcomes, such as quality of services and access to care, have not been established in the literature, although there is consensus that dual practice likely contributes both positively and negatively. Validating the CLD and translating it into a system dynamics model could be relevant in policy discussions as a platform for testing various policy scenarios and anticipating unintended feedback in the system.
The unintended feedback revealed through the CLD, at times detrimental to the public health sector, confirms the recommendations of previous studies, which proposed that a ban on dual practice would not be practical or effective[14–16, 40]. Periodic threats of banning dual practice also risk destabilizing the public health sector in places like Uganda, primarily by reducing the supply of government health workers. The private for-profit sector allows government providers the additional financial resources that the Ugandan government is currently not able to supply. In a relationship of mutual dependency, government providers in dual practice allow for the growth of the private for-profit sector in the context of limited health workforce and increasing population demand.
In the short term, the Ugandan government should consider the promotion of policies that are flexible to local adaptions to promote access and quality of services in the public sector, while at the same time allowing sufficient income for government providers. Informal, local adaptations to managing dual practice exist in Uganda and provide a natural experiment for various dual practice policies. In the long term, the Ugandan government should consider broader improvements to public sector management and increasing the resources available to the health sector, as well as increasing synergies with the private sector.
Reforms currently under discussion in Uganda include health insurance and performance-based contracts, both would change how providers are paid. Such reforms could potentially provide an entry point for strengthening public sector management in general, and therefore provide health facility managers the tools they are currently lacking to manage dual practice. As dual practice is unlikely to disappear in the short term, its existence and role in the health sector cannot be ignored during the design and implementation of major health reforms in Uganda and other countries where dual practice exists. Potential unintended effects (feedback) should be anticipated based on past events related to dual practice and dealt with accordingly.
This paper is part of the Thematic Series entitled: "Advancing the application of systems thinking in health." The Series was coordinated by the Alliance for Health Policy and Systems Research, World Health Organization. The publication of the Series and the associated capacity building and dissemination activities were carried out with the aid of a grant from the International Development Research Centre, Ottawa, Canada.
The authors would also like to give thanks to Ms. Taghreed Adam and to the two reviewers of the paper, for their insightful suggestions.
