Performance-based financing kick-starts motivational “feedback loop”: findings from a process evaluation in Mozambique

Abstract

Background

Performance-based financing (PBF) reforms aim to directly influence health worker behavior through changes to institutional arrangements, accountability structures, and financial incentives based on performance. While there is still some debate about whether PBF influences extrinsic or intrinsic motivators, recent research finds that PBF affects both. Against this backdrop, our study presents findings from a process evaluation of a PBF program in Mozambique, exploring the perceived changes to both internal and external drivers of health worker motivation associated with PBF.

Methods

We used a qualitative research design with in-depth, semi-structured interviews with health workers, which included a rank order exercise and focus group discussions. Interviews were analyzed by two researchers using thematic analysis techniques. Rank order frequency was calculated using weighted average methodology.

Results

Health workers reported that PBF, overall, positively influenced their motivation by introducing or reinforcing both internal and external motivational drivers. Internal drivers included enhanced self-efficacy driven by goal orientation, healthy competition among colleagues, and job satisfaction. External drivers included an organized work environment, enhanced access to equipment and supplies, financial incentives, teamwork, and regular consultations with verifiers (a type of supervision). PBF stimulates an interactive relationship between internal and external motivational drivers, creating a feedback loop involving responsibility, achievement, and recognition, which increased perceived motivation.

Conclusions

The PBF program helped workers feel that they had well-defined and achievable goals and that they received recognition from verification teams, management committees, and colleagues due to enhanced accountability and governance. Our paper shows that financial incentives could serve as the “driver” to kick-start the feedback loop, of responsibility, achievement, and recognition, in environments that lack other drivers. Understanding how PBF programs can be designed and refined to reinforce this feedback loop could be a powerful tool to further enhance and track positive motivational changes. For countries thinking about PBF, we recommend that policymakers assess the loop in their contexts, identify drivers, determine whether these drivers are sufficient, and consider PBF if they are not.

Trial registration

We obtained ethical approval for the study protocol, data collection instruments, and informed consent forms from the Ethics Review Committee of the Centers for Disease Control and Prevention (CDC) [IRB 2015–190] and the Ethics Review Committee of the Mozambique Ministry of Health.

Background

Health systems in low- and middle-income countries (LMICs) are plagued by several challenges, including weak management structures, inefficient information systems, and poor accountability for performance [1]. Health sector performance is critically dependent on health worker performance because service quality, as well as the accessibility and efficiency of health service delivery, is directly mediated by workers’ ability and willingness to apply themselves to their tasks [2]. Resource availability and worker competence are essential but not sufficient to ensure desired worker performance [3]. Hence, motivation—which we define as an individual’s degree of willingness to exert and maintain effort toward organizational goals [2]—is critical for ensuring that qualified workers perform well. Against this backdrop, performance-based financing (PBF) has emerged as a promising intervention for improving the delivery of high-quality healthcare services by enhancing health worker motivation.

A handful of studies have investigated whether PBF does indeed enhance health worker motivation, with mixed results. In Nigeria [4], Burundi [5], Tanzania [6, 7], and Sierra Leone [8], PBF had an overall positive effect on motivation, whereas in Benin [9], DRC [10], Pakistan [11], and Zambia [12], PBF did not appear to change levels of health worker motivation. In Afghanistan, PBF was negatively associated with motivational factors, although it had a significant positive effect on quality of care [13].

Motivation is often conceptualized using an intrinsic-extrinsic dichotomy, where behavior is categorized as extrinsically or intrinsically motivated based on whether or not it was induced by some external stimulus [14, 15]. PBF as an intervention—particularly the individual financial incentives, which are part of most PBF schemes—is believed to primarily enhance extrinsic motivation. However, elements of PBF may foster both extrinsic and intrinsic motivation. Evidence on the motivational mechanisms of PBF remains scarce, but some studies have found that PBF can stimulate intrinsic forms of motivation, such as transforming the work environment [4, 9, 12, 16, 17], giving health workers opportunities to improve skills, enhancing recognition from the community [4, 19], and strengthening professional pride and responsibility [9, 19]. It thus appears that PBF as a complex systems intervention has the potential to influence many different types of motivational determinants [20,21,22].

This study explores the different ways PBF influences health worker motivation in the context of a PBF pilot in Mozambique. Our objective is to assess the perceived changes, by health workers, on motivational drivers associated with the introduction of PBF.

Study setting

The CDC PEPFAR program in Mozambique financed the implementation of a PBF program targeting government-owned health facilities in two provinces of Mozambique (Gaza and Nampula) in early 2011. By 2015, the PBF program included 138 health facilities (73 facilities in Gaza and 65 facilities in Nampula), but was ended in 2016 and never scaled past these two provinces.

The program focuses on providing HIV-related services, primarily for pregnant women and children. Twenty-one incentivized indicators are clustered in four groups by the type of service: prevention of mother-to-child transmission (PMTCT), pediatric HIV, adult HIV/TB, and maternal and child health (MCH). Payment is based on the sum of three components: quantity, quality, and equity (for rural and hard-to-reach areas). Health facilities report on PBF indicators monthly and submit aggregated reports on a quarterly basis. Data verification and payment cycles occur every quarter and are conducted jointly by the implementing NGO and the Provincial Health Office (DPS). PBF earnings are re-invested in the facility (40%) and used to provide salary top-ups to staff (60%). Salary top-ups are distributed among all health facility staff based on such pre-determined criteria as years of experience, facility tenure, level of education, and professional position. According to internal program data, salary top-ups account for between 20 and 50% of an average health worker’s salary, and facility investments for approximately 50% of total facility operating costs.

Methods

Data collection and analysis

To understand perceptions of health worker motivation, we used a qualitative research design with in-depth, semi-structured interviews, including a rank order exercise and focus group discussions. Our sample included 56 health workers and administrators (Table 1). Motivational determinants were identified through a free-listing exercise where health workers were first asked to define motivation and then asked to write a list of all the determinants or drivers of motivation associated with their jobs in June 2015. They were then asked to describe changes they observed within the health facility since the introduction of PBF and to reflect on the positive, negative, or null changes related to PBF across 15 motivational determinants (Table 2).

During in-depth interviews and focus groups, clinic-focused health workers completed an exercise with the 15 determinants, ranking them from the most to least, or not at all, influenced by PBF. Data were collected, between November and December 2015, at 17 public (government-owned and government-operated) health facilities in Nampula (nine) and Gaza (eight), 76% of them primary health centers and 71% classified as rural or peri-urban. We selected a range of facilities based on size, geographic location (rural, peri-urban, urban), and facility performance data. Each facility had participated in the PBF program for a minimum of 18 months.

All interviews were conducted by two researchers and transcribed in Portuguese, then imported into ATLAS.ti version 1.0.14 for thematic analysis. Two or three researchers conducted focus group discussions in three urban (two Gaza, one Nampula) and three rural (one Gaza, two Nampula) health facilities. Two researchers coded interviews line-by-line and analyzed them to identify recurring themes and variations across responses. Initial themes and sub-codes were organized based on the theoretical model of intrinsic and extrinsic dichotomy, although interactions and relationships between domains were further noted through memos and subsequent coding. Differences among health worker cadres, provinces, and health facility level were all assessed based on coding patterns and quotations for each dimension. Rank order frequency was calculated using weighted average methodology for determinants most influenced by PBF.

Results

Health workers reported that PBF had influenced motivation in direct and indirect ways, with 11 motivational determinants ranked as influenced by PBF (Table 2). Four determinants were grouped together during the analytical process due to similarity in description and conceptualization by informants (see notes below table). Four determinants were identified as not influenced by PBF. There were no notable differences between the responses or rankings in the two different provinces.

Key motivational determinants

More organized work environment

Health workers described PBF as a tool for creating a more organized work environment. Medical and office supplies required for day-to-day work were more readily available, enhancing efficiency and comfort. Workers felt that PBF had changed their typical workflow, by organizing the environment and patient books, increasing coordination of which patients they should see or follow up.

There were several notable structural changes that health workers reported. The physical appearance of the facilities, including wall painting, infrastructure upgrades (e.g., latrines and septic tanks), and cleanliness (less trash, more waste bins available, clean consultation rooms), was most frequently reported. For health facilities with “deteriorating infrastructure and inadequate equipment and supplies,” PBF transformed the facility with “newly painted walls with functional windows and doors and general cleanliness.” These structural improvements influenced workers’ pride in and satisfaction with the appearance of their facilities.

Respondents further described how PBF introduced specific, timely, and frequent verification processes, whereby provincial project staff and DPS would visit each facility on a consistent and planned basis, and verify the reported data through register checks. Facilities reacted by instituting daily and weekly record-keeping and self-verification to ensure the completeness and quality of the data. Management committee meetings were conducted monthly to plan and discuss PBF.

Ability to perform well

Health workers reported being more committed to their work, giving up other personal and professional duties to ensure they completed tasks and increased the success of PBF in their facilities. Doing a “good job” was perceived as following instructions, completing the registry, and communicating with team members. They also linked doing a good job to adherence to clinical protocols; while health workers reported having access to and understanding correct clinical protocols even before PBF, the scheme increased attention to the protocols as well as accountability for adherence. In general, all respondents suggested that their colleagues were as committed to and proud of the work as they were themselves.

Bonus or salary top-up

Although respondents did not rank performance bonuses as the most significant aspect of PBF that enhanced their motivation, every health worker interviewed described the effects of incentives in their work. The financial bonus made the health workers feel more appreciated and respected. Workers felt that the bonus made it worth completing their work, despite challenges. Payments were timely, and some facilities made efforts to increase transparency of incentives by posting what everyone received on the health facility bulletin.

While the salary top-ups were widely appreciated, some workers felt that the distribution of funds was unfair. They questioned the higher bonuses that technicians and physicians received, even though lower-level cadres such as nurses and lay counselors exerted greater effort. Most nurses interviewed argued that since everyone was working together to maximize payments, they should all benefit equally. Further, for health workers at larger facilities, the bonuses were reportedly too small to dramatically influence behavior or motivation. According to program data, staff bonuses represented 15% to 25% of the monthly salary for higher-level health staff (e.g., doctors) or for those working in larger facilities and 30% to 50% of the monthly salary for lower-level staff (e.g., activists, janitorial technicians) or for rural staff in small facilities.

Constructive competition and teamwork

Respondents reported that PBF had introduced healthy competition among colleagues. Health workers were more conscious of the work completed by colleagues, which inspired each to work hard to earn their “piece of the pie.” PBF created this sense of competition by refocusing on performance, enhancing transparency, and increasing accountability.

Management boards were formed as a part of the PBF program for facility fiscal planning, but often included only facility administrators (e.g., head nurses and senior medical technicians). Workers felt that they were “left out of important decisions for the facility” because the management boards were neither participatory nor inclusive of their opinions and concerns. In contrast, the fact that everyone received a bonus meant that all health workers were more motivated to help each other with clinical tasks. Most noticed increases in the frequency of communication with other workers assigned to different services as well as meetings with the DPS and the implementing NGO’s teams.

Satisfaction with personal performance

Health workers felt that while PBF resulted in a heavier workload, it also enhanced their drive to complete more of their tasks, which led to a feeling of job satisfaction. Respondents agreed that workflow and managerial organization had improved, which enhanced workers’ ability to finish clinical tasks. Receiving recognition from verifiers or DPS supervisors led workers to report feeling greater job satisfaction.

Regular consultations with supervisors

PBF did not directly affect the physical presence of district supervisors or use of supportive supervision techniques. However, health workers said that the frequency and consistency of visits by verification teams were positive changes. The workers felt constantly monitored but were happy about the “supportive” nature of the supervision they received from the verification team.

Interactive effects: PBF feedback loop

Health workers often described how the changes in motivational drivers to PBF were interactive. External changes triggered other changes in their intrapersonal motivational drivers and vice versa. Figure 1 displays this motivational feedback loop created by PBF’s institutional and organizational components.

Over two thirds of workers believed PBF had resulted in a shift in orientation toward clearly defined goals. Workers were better able to identify the facility’s performance goals, feel responsible for these goals, and focus their efforts on “doing their job.” Moreover, sharing the same goals inspired a feeling of camaraderie throughout the facility.

Respondents linked clarity of goals with feelings of ownership and efficacy, which ultimately resulted in greater motivation. They credited frequent verification for engendering greater accountability around individual and facility performance. They also reported feeling more motivated to achieve shared goals because they could do their jobs more effectively, given changes in the work environment. In their view, PBF had improved facility infrastructure, staff relationships, and workflow.

Achievement

Many health workers described how PBF instilled in them a new sense of accomplishment and professional pride, which they viewed as highly motivating. This new sense of achievement was brought about by introducing and institutionalizing performance monitoring and managerial processes, or “regimenting” of the health facility. Respondents viewed this as a crucial driver of performance and of heightened feelings of motivation and job satisfaction.

Recognition

The achievement of well-defined goals resulted in rewards, both financial and non-financial. Good performance led to increased bonuses for workers, as well as greater worker investment in the health facility. Most workers were very happy to receive additional payments and reported that it boosted morale and allowed them to take care of their families. These bonuses motivated them to work harder (longer hours, lower absenteeism) and communicate more frequently with other clinical team members. The reward itself garnered recognition from family and close friends.

Beyond the payments, workers also reported feeling recognized for their work through the PBF program’s measurement and verification of results. Health workers described how the accountability and governance mechanisms institutionalized in the context of PBF allowed for more praise and positive reinforcement from verification teams, management committees, and the community.

Discussion

PBF is a policy reform that aims to directly influence health worker behavior through several mechanisms, including changes to institutional arrangements, accountability structures, and financial incentives based on performance [20, 23,24,25]. The increasing use of PBF demands a more in-depth and comprehensive understanding of how PBF influences health worker motivation and behavior [25,26,27]. Research on PBF indicates that some PBF schemes do have the capacity to enhance overall motivation for providing PBF-targeted services [18, 28,29,30,31]. The effect of PBF on motivation is usually explained as a stimulus or extrinsic driver of motivation [32]. The literature documenting PBF’s effects on health worker motivation, however, suggests that this conceptualization might be too narrow to adequately capture the complex motivational effects of PBF [12, 18, 33, 34].

In line with this body of literature, our results show that health workers perceived both external changes in the work environment and changes within themselves that enhanced or hindered feelings of motivation. Health workers described how the PBF program has significantly improved the organization of the facility and the availability of equipment and supplies required for their day-to-day job activities, which they found to be motivating. Results from Nigeria and Benin captured a similar relationship between health worker motivation and working conditions [27, 35]. PBF program designers and implementers should note that the structural changes and re-investment in the facility can motivate staff and make it easier for them to do their jobs.

Workers also shared a positive perception of incentives, supported by the sense of accomplishment and satisfaction of earning an additional reward. The aspiration for additional income or consistent improvement of health facilities motivated staff to provide patient care aligned with PBF targets or what they referred to as goals [32]. In some cases, distribution of incentives created feelings of unfairness because certain cadres or workers with heavier patient loads or administrative duties felt that they should receive a higher proportion of the bonus compared to facility staff who do not work on PBF services. Similarly, in larger facilities with many staff, the incentives were very low and subsequently were not a significant source of enhanced motivation.

Existing PBF schemes differ considerably in terms of both the share of PBF payment that is reserved for salary bonuses (versus investment in the facility) and how the bonuses are divided between staff. One review of 20 PBF schemes showed that staff bonuses as a share of total PBF payments varied between 25 and 80%, and documented a variety of formulas for distributing payments among workers within a facility [30]. Given the evidence that incentives can be a motivational driver in PBF, more research is required to understand how PBF payment formulas and allocative disbursements between facility investment and individuals can drive both motivation and overall health system strengthening.

The broader health system literature shows that internal motivational drivers are equally important in shaping health worker motivation [18]. In Mozambique, health workers reported changes in improved teamwork with colleagues, pride and satisfaction associated with completing their work, and appreciation from verifiers and colleagues. In other LMICs, internal motives, a sense of responsibility, pride in one’s work, and recognition from the community have been shown to be key motivational drivers [36,37,38]. From the health worker’s perspective, the changes contributing to such enhanced feelings included strengthened management structures, primarily through the verification process and by facility administrators checking on service delivery and the register [39, 40].

Importantly, our findings found that PBF strengthens an existing feedback loop, exhibited most clearly when providers described changes to internal and external drivers together and in a specific cascade. One of the most common interactive descriptions involved financial incentives that resulted in other external and internal shifts in motivation. Financial incentives were perceived as highly influential and reportedly increased health workers’ motivation to exert additional effort to meet increased demand, feel pride in one’s work, and communicate with one another about service delivery. Further, when questioned about how PBF creates and sustains changes in perceived motivation, a feedback loop involving responsibility, achievement, and recognition. The institutional and organizational arrangements that PBF changed helped facilitate this cycle or feedback loop and helped workers feel that they had well-defined, achievable goals to work toward, while accountability and governance meant that many health workers received praise from verification teams, management committees, and colleagues.

Although this interactive relationship has not been made explicit in PBF publications, feedback loops are an integral component of all systems and evidence of this feedback loop is supported by evidence. For instance, in Zambia, PBF enhanced job satisfaction through better working conditions and more effective supervision, in addition to higher job satisfaction with compensation, feelings of accomplishment, and financial autonomy [12]. In Malawi, health workers were motivated by the goals and direction introduced by PBF [18]. A more enabling working environment induced by PBF (e.g., improved resource situation, enhanced supervision, better management support) (1) allowed health workers to improve their performance by aiming for these goals, (2) created new feelings of self-efficacy and pride as health workers recognized their accomplishments, and (3) were positively reinforced by managers, the community, and implementers, verbally and through PBF rewards. This fueled a positive spiral of motivation to continuously improve performance [18].

Limitations

The methodology adopted in this study—capturing information on the effects of PBF health systems through semi-structured interviews with health workers—has several limitations. First, respondents were selected in collaboration with facility management, which could have led to a biased sample of motivated or positive health workers. Although the evaluation was conducted by a third-party evaluator, project implementers and occasionally DPS accompanied our data collectors to the facility to facilitate the introduction and coordination of the interviews; their presence could have influenced the views expressed by study participants. The interview guide was open-ended, but all health workers were probed on personal motivational changes attributed to PBF. The motivational determinants were defined through free-list exercises with health workers not included in the study but working in the same provinces as comparable health facilities prior to the data collection period. The probing may have introduced concepts that the workers would not have mentioned or noted on their own.

Conclusion

Our study found that PBF led to changes in both internal and external drivers of health worker motivation and created an interactive feedback loop involving responsibility, achievement, and recognition. The institutional and organization arrangements that PBF created allowed for workers to feel that they had well-defined goals and could achieve these targets, and accountability and governance allowed for many health workers to receive praise from verification teams, management committees, and colleagues.

Our paper shows that financial incentives can serve as the “driver” to kick-start the loop in environments that lack other drivers. For countries thinking about PBF, we recommend that policymakers assess the loop in their contexts, identify drivers, determine whether these drivers are sufficient, and consider PBF if they are not.
