Abstract

Background Several performance-based financing (PBF) evaluations have been undertaken in low-income countries, yet few have examined community perspectives of care amid PBF programme implementation. We assessed community members’ perspectives of Support for Service Delivery Integration - Performance-Based Incentives (‘SSDI-PBI’), a PBF intervention in Malawi, and explored some of the unintended effects that emerged amid implementation.

Methods We conducted 30 focus group discussions: 17 with community leaders and 13 with mothers within catchment areas of SSDI-PBI implementing facilities. We analysed data using the framework approach.

Results Community leaders and women had mixed impressions regarding the effect of SSDI-PBI on service delivery in facilities. They highlighted several improvements (including improved dialogue between staff and community, and cleaner, better-equipped facilities with enhanced privacy), but also persisting challenges (including inadequate and overworked staff, overcrowded facilities and long distances to facilities) related to services in SSDI-PBI-implementing facilities. Further, respondents described how four targeted service indicators related to maternal risk factor management, antenatal care (ANC) in the first trimester, skilled birth attendance and couple’s HIV testing sparked unintended negative effects as experienced by women and communities. The unintended effects included women returning home for delivery, women feeling uncertain about their pregnancy status, women feeling betrayed or frustrated by the quality of care provided and partnerless women being denied ANC.

Conclusion PBF programmes such as SSDI-PBI may improve some aspects of service delivery. However, to achieve system improvement, not only should necessary tools (such as medicines, equipment and human resources) be in place, but also programme priorities must be congruent with cultural expectations. Finally, facilities must be better supported to expect and then address increases in client load and heightened expectations in relation to services.

Key questions

What is already known?

  • There is mixed evidence on the impact of performance-based financing (PBF) programmes on health service utilisation and quality of care.

  • Little is known on how communities experience care under PBF.

  • Limited literature available indicates the emergence of unintended consequences concerning healthcare delivery under PBF.

What are the new findings?

  • Beyond positive impacts on service delivery, unintended negative effects may emerge due to implementation realities and can affect community experiences of care.

  • PBF ability to produce change is constrained by health system factors which affect the implementation reality.

What do the new findings imply?

  • Health system factors and the socio-cultural elements should be taken into consideration when implementing PBF programmes.

  • Facilities must receive additional structural and human resource support to address both increased service load and enhanced expectations on quality of care induced by PBF.

Background

Malawi has made considerable progress in improving health in recent decades, yet challenges particularly related to maternal health remain. The country is among the most dangerous places in the world to become a mother;1 one in 34 Malawian women will die due to maternal causes in her lifetime.2 3 Several programmes and policies unveiled in recent years both within Malawi and globally have sought to address maternal health. An intervention that has garnered considerable attention is ‘performance-based financing’ (PBF).

PBF is a health system intervention that provides incentives (monetary or tangible) to health facilities ‘for delivering specific services, provided the services follow explicit protocols, with a system of inspection and auditing to assure compliance’.4 Under PBF, the health service purchaser (such as a Ministry of Health or implementing body) works with health administrators and providers to devise performance contracts, which define both the performance indicators to be achieved and the manner to reward their achievement.5 Further key PBF elements aimed at supporting facilities in improving performance include increased management autonomy at the level of the single facilities and intensified service delivery monitoring and supervision by both health system and community stakeholders.6 7

Evidence from PBF programmes across low- and middle-income countries is mixed in regard to its impact on service utilisation and quality.8 9 PBF has been observed to yield a positive effect on maternal care services in Rwanda,10 Burundi11 and Tanzania,12 but not in Afghanistan;13 a positive effect on childhood immunisations in Cameroon14 but not in Rwanda,10 Afghanistan13 or Burkina Faso;15 and mixed effects on various indicators of quality of care.9 Incentives have also been associated with drawbacks such as gaming by providers to maximise results16 and perceptions of unfairness among providers in rewarding performance that negatively affects delivery of quality of care to clients.17–21

Although an increasing number of studies have explored quality of care within PBF, most of these are quantitative studies.10–13 22 Qualitative studies have primarily explored insights from providers.23–25 Literature on PBF experiences by community members and healthcare clients is rare.24 26–29 This is despite evidence of some unintended outcomes regarding provider behaviour towards clients.20 24 For instance, in an evaluation of another PBF programme in Malawi, women reported improvements in certain aspects of quality of care, but also continued incidences of disrespectful care in spite of the fact that the PBF intervention was coupled with conditional cash transfers to support women delivering at selected health facility.27 An evaluation in Tanzania found that providers developed strategies to reach targets that could be harmful to clients.30 They threatened to fine women, and to deny their children immunisations and health records if women did not deliver in a health facility.23 Studies in Rwanda and Malawi found that health workers documented the care provided retrospectively in order to fulfil a target of ‘completed forms’ which was required to receive incentives.16 21

The main objective of this study is to explore collective perceptions of care by community members—including both clients and community leaders—during the implementation of the Support for Service Delivery Integration - Performance-Based Incentives (SSDI-PBI) programme in Malawi, a particular PBF programme which did not tie performance incentives to individual health worker gains. Sub-objectives included exploring community and clients’ perspectives on the improvements produced by the programme and remaining challenges. While not initially an aim of the study, we also highlight some of the unintended programme effects revealed by clients. Not only is an exploration of service users’ experiences valuable in understanding how PBF affects maternal care provision and use, but capturing clients' perspectives is crucial to guide recommendations regarding whether and how to modify health programs in the event of scale-up.

Methods

Study setting

Malawi is a low-income country with an economy largely dependent on agriculture, and a health system largely dependent on foreign aid.31 One quarter of the country’s estimated 17.5 million citizens live in extreme poverty.31 Health institutions are either government-owned or faith-based organisations, with only a minority being managed by for-profit private institutions.32 Across all districts, implementation of health interventions is guided by the health sector strategic plan, which emphasises improving service coverage via an essential healthcare package (EHP).32 The EHP states a stipulated set of health services covering the most common conditions be delivered free of charge at point-of-use in public facilities and in private facilities contracted via service-level agreements.32 Utilisation of healthcare services is relatively high, but EHP services are often inadequately provided33 due to a shortage of human resources, poor infrastructure, lack of medical equipment and supplies and inadequate financing.34 This situation has resulted in slow progress towards reduction of morbidity and mortality in the country.35

In trying to address these challenges, the government of Malawi explored PBF as a means to improve access to health services of high quality. The country recently concluded the implementation of two PBF-specific programs entitled ‘Results Based Financing for Maternal and Neonatal Health’ (RBF4MNH),36 and ‘Support for Service Delivery Integration - Performance-Based Incentives’ (SSDI-PBI).37 The focus of this paper is the latter programme, SSDI-PBI, implemented in 17 facilities across three districts: Mangochi, Nkhotakota and Chitipa.

The intervention

The SSDI-PBI programme and its implementation processes have been described in detail elsewhere.37 The programme, which lasted 2 years, was introduced in 2014 into a context where: funding for health resources was largely input based; financial autonomy was held at district and higher organisational levels (with health facilities holding limited control over their own resources); accountability of health facilities to the health system or communities was largely informal and inconsistent and severe general shortages in human and material resources persist.33 38 SSDI-PBI is similar to other PBF programs in that rewards were provided to health facilities on provision of a predefined set of health services stipulated in a service contract. In SSDI-PBI, improved service provision aimed to increase utilisation rates (also called ‘quantity indicators’ (online supplementary file appendix 2)) across the maternal health continuum (during antenatal, delivery and postpartum periods), newborn and child health and HIV and AIDS care and treatment. Quality indicators emphasised improvements in both the facility environment (eg, clean rooms that offered privacy) and how care was provided (eg, medical equipment was available and functioning), see online supplementary file appendix 2. In addition, the programme relied on an explicit community assessment of quality of service provision (via community meetings defined as ‘community scorecards’ and exit interviews). Payouts to facilities were made based on the joint assessment of quantity indicators, quality indicators and the community scores.

The specific focus of this qualitative study on maternal care arises from the fact that while SSDI-PBI did not exclusively address maternal care services, the intervention aimed to improve maternal health by increasing the quantity (service coverage rates) and quality of: antenatal care visits within the first trimester, births attended by a skilled birth attendant (a doctor, nurse or midwife), postnatal care within 7 days of delivery and patients counselled for family planning.

The SSDI-PBI programme was different from many other PBF programs in at least two respects: (1) the programme did not provide any monetary incentives (in the form of salary bonuses) to individual health workers; and (2) the programme's incentives were exclusively goods-based, with the implementing agency coordinating the procurement and distribution of supplies and equipment to facilities in line with targets and incentives set in the facility business plan.39

Study design

This qualitative study was embedded within a broader mixed-methods evaluation of SSDI-PBI.37 Since our study aimed to explore group perceptions and experiences of SSDI-PBI, we employed qualitative methods.40 41 Because the team was interested in social norms, conversational interactions and bringing to the surface perspectives of the community in relation to healthcare amid SSDI-PBI, focus group discussions (FGDs) were used.

Data collection

Data collectors were trained for 5 days (including pilot testing). Data collectors had previous experience collecting data to inform health interventions, and they had academic training in nursing, journalism, midwifery, social work, education, administration or medicine. The qualitative training emphasised the SSDI-PBI intervention, FGD techniques and ethics. In March 2016, we conducted 17 focus group discussions with 4 to 12 community leaders per FGD across the 17 facility catchment areas (one FGD per facility). We also conducted 13 FGDs with 5 to 10 mothers in the catchment areas of 13 facilities (FGDs were concluded on saturation of themes). Community health workers (including health surveillance assistants and volunteers) assisted in identifying participants. In addition, data collectors canvassed villages and invited those present (and eligible) to participate. Sampling was purposively focussed on gathering perspectives from those living in the catchment areas of SSDI-PBI implementing facilities who were either mothers or community leaders (village health committee members, ward councillors, chiefs, village headmen, religious leaders and traditional healers). Topics across FGDs covered impressions of facilities, changes in facilities over time and knowledge and perceptions of the SSDI-PBI programme.

Techniques undertaken to collect trustworthy, high quality data followed the approach of naturalistic inquiry put forth by Lincoln and Guba (1985),42 including prolonged engagement, triangulation and reflexive dialogue (see table 1). Following each FGD, a lead researcher debriefed data collectors for information regarding emergent themes, reflexive insights and questions that could merit more deliberate follow-up in later FGDs.43 During these meetings, the research team spoke openly about their thoughts and perceptions of the programme (both positive and negative) in order to build reflexive memos that were used to further inform the conduct of later interviews and, ultimately, the coding process. Notes captured during these debriefings were also shared with the wider research team (including senior authors) and formed the basis for coding all FGDs. All FGDs were conducted in the local language (Chichewa), recorded, transcribed, translated into English and quality controlled by bilingual research assistants. FGD tools are included in online supplementary file appendix 1.

Data analysis

The first and second author analysed the data with support from all co-authors, drawing on the framework approach outlined by Pope.44 An inductive approach was used,40 meaning that themes were mainly generated from the data that were collected. First, the lead author repeatedly read transcripts and reviewed notes in order to gain familiarity with the data and understand connections across concepts.45 Second, the first author noted emerging themes from the text and coded chunks of data representing themes.45 Third, the first and second authors explored thematic areas by displaying the relevant coded text in each category to identify key themes and inter-relationships. Finally, all co-authors interpreted findings by discussing and agreeing on key themes that addressed the research question. The process was conducted using NVivo software.

Ethical considerations

Respondents were informed in writing and orally about the nature and scope of the study. Participation in the study was entirely voluntary. Informed consent was sought from all study respondents. Respondents signed or finger printed the consent forms to show that they understood the conditions of the study and had agreed to take part. Further, respondents were informed to be free to stop any time if they felt it was important for them to do so. It was also made explicit to them that doing so will not disadvantage them in any way.

Patient and public involvement

Neither patients nor the public were involved in the design, conduct, reporting or dissemination of our research.

Results

Tables 2 and 3 show key respondent characteristics. Leader focus groups consisted of between 4 to 12 predominantly male participants, with group composition ranging from all male to 60% female, most of whom took part in their role as traditional authority, health centre advisory committee member or religious authority. Women’s focus groups ranged from 5 to 10 respondents and were well balanced in regards to age, parity and pregnancy at the time of the FGD.

Characterists of participants in women's’ FGDs

We first present an overview of the experiences and perceptions of women and community leaders in accessing maternal services in the context of SSDI-PBI. We present results distinguishing between areas of services delivery where woman perceived notable improvements, areas where pre-existing challenges persisted and areas where new challenges (unintended consequences) of the SSDI-PBI intervention emerged. We then outline the processes by which well-intended service goals lead to unintended effects.

In terms of improvements and challenges, community leaders and women had mixed impressions regarding the SSDI-PBI programme’s effect on facilities (see table 4). They highlighted several improvements, but also noted persisting challenges related to services received from SSDI-PBI health facilities. Community leaders were generally more conversant on the programme, attributing changes explicitly to the SSDI-PBI programme. Women were less conversant on the programme, but could speak at length about changes observed within facilities in the preceding year (which aligned with the onset of SSDI-PBI). Stark or notable differences in perspectives did not emerge when comparing across facilities.

Table 4

Client and community leader perspectives on improvements and challenges amid SSDI-PBI

Notable improvements

The most fundamental improvement described by both respondent types involved the appearance of facilities. Both women and leaders described how facilities looked better; they were cleaner, more inviting, had more equipment, better landscaping, better fencing, bright curtains and (importantly for women) facilities began providing forms of privacy (such as screens) during childbirth. Across respondent groups—though not uniformly in catchment areas across facilities—respondents described a sense that facilities had a more consistent supply of drugs (several women mentioned iron tablets and Panadol), that providers were ‘better dressed’ and ‘doing more’ to reach clients living both near and far from facilities (particularly via ‘outreach clinics’), and that providers began to more heavily emphasise that women’s partners should be engaged in the care seeking process. Finally, community leaders in particular described how community-facility dialogue meetings provided a forum for clients to openly air ‘grievances’ and express their concerns to facility-based providers on topics such as client-provider interactions and opening hours. This was described as an awkward, sometimes combative endeavour, but was viewed as ultimately beneficial among leaders as it compelled providers to feel more beholden to the communities they serve and, as one leader said, ‘to view us as people’. Leaders also mentioned that via discussions with providers, they learnt that they had a responsibility, as leaders, to advocate for the intervention; leaders described taking providers' messages to heart and thus encouraging men to accompany women to facilities, and encouraging women to visit facilities earlier in pregnancy, and to give birth in facilities. FGDs with women triangulated these findings.

Persistent challenges

The most fundamental persisting challenge described by both respondent types involved a sense that providers were ‘overworked’, ‘unhappy’, ‘bitter’ or ‘under stress’. Respondents were careful to note that there was not a negative change per se, as providers were not previously happy or stress-free. But since the onset of SSDI-PBI, respondents felt that providers had more demands placed on them without necessarily receiving additional human resource support. SSDI-PBI exacerbated pre-existing shortfalls, particularly when the programme was in its earliest stages. Other persistent challenges related to factors that respondents had thought would change (or should change) in tandem with the aforementioned improvements. For instance, respondents noted that there was outreach to attract more women to attend facilities earlier in pregnancy (this was viewed as an improvement); however, this outreach—and the earlier care-seeking it compelled—were not accompanied with improvements in availability of pregnancy test kits which meant that women saw no purpose in seeking care earlier. Women and leaders also highlighted that facilities remained overcrowded (a situation viewed as heightened amid PBI), that recently-delivered mothers were forced to share beds (a situation described as preceding PBI, but also exacerbated by it) and that many challenges related to distance such as pregnant and labouring women travelling far to reach facilities were not overcome. In contrast to what clients perceived in some facilities where drug supplies appeared to have improved, other facilities appeared to have exacerbated drug shortages.

How unintended effects can exacerbate challenges

Across the SSDI-PBI facility catchment areas, respondents described their experiences of maternal and child healthcare in a manner that underscored how complexities are likely to arise when a programme is implemented in a setting that lacks necessary resources (such as medicines, equipment or health personnel) or when the priorities of the programme do not dovetail with the values, norms or preferences of the community (such as setting targets that collided with local gender norms). Four targeted service indicators were described as sparking unintended negative effects after they were introduced as part of SSDI-PBI. In figure 1, we highlight leaders’ descriptions of four targeted services (column A), leaders’ descriptions of how providers operationalised the services (column B), how the operationalisation of the target was received and/or perceived by communities (column C) and the unintended consequence that eventually unfurled (column D). While figure 1 and this text emphasise negative unintended consequences, we note that clients viewed many positive effects of PBI (see table 1) yet positive consequences were viewed as both expected of and intended by the programme.

Compelling home delivery

The SSDI-PBI programme sought to increase the proportion of skilled attendance at birth and referral of high-risk pregnancies to higher-level facilities. Leaders and women reported that the importance of giving birth in facilities was reiterated to them in the course of the programme. Leaders described telling women that they must go to facilities; women confirmed that they had received such messages from leaders. Women and leaders described thinking that the care on offer would be notably improved because the SSDI-PBI programme placed such an emphasis on making sure care was sought in facilities. Leaders and women thus described disappointment with the level of crowding in facilities, and felt frustrated that issues of disrespectful maternity care such as feeling disregarded and/or talked down to by overworked or absentee providers during delivery were unchanged or in some cases perceived to have worsened.

Women who were identified as at-risk said they were now being referred to higher-level care, but were not afforded the means (whether funds for public or private transport, or access to a free-of-charge option such as an ambulance) to make a referral logistically or financially feasible. Although women were encouraged to save funds during pregnancy, this guidance felt hollow or out of touch in the context of poor crop yields, fuel shortages and generalised poverty. Leaders confirmed that referral, which they described as a message underscored in the programme, can be futile and dangerous as it could lead to births en route if families lack financial or logistical means to reach a facility or to sustain oneself once at a facility.

Several women and leaders expressed frustration; respondents felt that they were strongly encouraged to support delivery in facilities as a direct result of PBI but this encouragement was not accompanied with improvements that would make women feel safer during childbirth. Paradoxically, the insistence that women attend facilities for birth led to instances of reinforcing underlying aversions to facility delivery.

Confusion among women regarding pregnancy

The SSDI-PBI programme sought to increase the number of pregnant women starting antenatal care (ANC) in the first trimester. Leaders and women described knowing that this was a priority of the programme due to key messaging during outreach clinics and other health communication campaigns, and a behaviour that needed to be modified in the context of the programme. Women then assumed that there was a purpose in attending facilities for earlier ANC; that more care would be provided and/or more tests would be done to determine the existence and health of a pregnancy. Women described attending facilities earlier in their pregnancies, but being disappointed to discover that they would not be given a pregnancy test, nor would they receive any additional care. Women said providers merely palpated their abdomen but could not confirm a pregnancy status and thus could not provide pregnancy-related care. This left many women disappointed, as they remained uncertain of whether they were pregnant and they felt the time and energy required to forgo other activities in favour of seeking ANC was in vain. As one woman, age 24, from Facility 5 said, “They couldn't tell me anything! They couldn't even tell me how many months my pregnancy was”. The experience led several families to feel less certain about whether they were pregnant (since providers could neither confirm nor refute a pregnancy status); women also felt unsure of how their pregnancy may be progressing since no additional tests were conducted until a woman's status could be definitively (visibly) confirmed. This study was not designed to evaluate whether there was a quantifiable decline in the proportion of women given adequate care when presenting to the health facility. Deficiencies in care provision are likely to have existed before and persisted through PBF implementation. Women’s reports suggest that SSDI-PBI sensitised communities to the issue, thereby sparking disappointment, irrespective of changes or lack thereof in actual quality of care.

Burdens, delays and familial discord

The SSDI-PBI programme sought to increase couples testing for HIV. Leaders and women did not describe being knowledgeable about this priority specifically, but they were aware of an increased insistence on having men accompany their partners to facilities during pregnancy (whereupon HIV tests were advised and routinely administered). Several leaders described being co-opted by facility-based staff to enforce a community-wide mandate that all pregnant women must attend ANC with their partners. Women concurred with this; they described how care was delayed or denied (particularly during early ANC visits) if they did not have an accompanying partner. The situation of needing a partner at ANC visits placed several women in a dilemma. A man could refuse to accept or publicly recognise paternity, or he may be constantly travelling and thus unavailable for health-related appointments. As one woman, age 30, from Facility 5 said, "I started going to antenatal at 5 months …it would be possible to go at 3 months, but I failed because my husband was in South Africa. … I waited for my husband to be back from the trip, because if I went on my own I could have been sent back”.

Alternately, a woman may prefer not to disclose the identity of her unborn baby’s father. In more mundane scenarios, boyfriends, partners or husbands could simply refuse to attend ANC, arguing that they feel unwelcome at health facilities or that their time is better spent earning money for their families. Women who struggled to get a partner to attend described delaying their first ANC visit and ultimately attending ANC alone (whereupon they were afraid of being scolded for not bringing a partner). In instances when men did accompany women, men were described as complaining that they felt uncomfortable in what was perceived as a female-dominated sphere, that they viewed facilities as overcrowded and that they felt awkward discussing health matters—especially regarding HIV—within listening distance of others. In still other instances, women resented that those who had a husband or male partner with them received faster or preferential treatment, which seemed to suggest that a man’s presence lent more credence to a woman’s health needs.

Discussion

This study outlines community perspectives on improvements, persisting challenges and unintended negative effects throughout implementation of the SSDI-PBI programme. The findings contribute to the PBF literature in at least two ways. First, this study draws in insights from community leaders and childbearing women, perspectives that are often overlooked in academic literature related to PBF. Second, by presenting unintended effects that unfurled in the SSDI-PBI programme, the study highlights an under-researched area in the broader PBF literature and draws implementers’ attention to critical issues that may constrain or undermine success in similar programs.24 46

In terms of improvements experienced during the SSDI-PBI programme, similar to other PBF studies, findings suggest that such interventions can strengthen availability of resources and the amount and depth of dialogue between health providers and their catchment communities.47 48 It should be noted, however, that our article reports on community perceptions and does not attempt to quantify changes in quality of care, measured in terms of either resources or patient-provider dialogue. Findings relating to medical supplies echo PBF studies in Rwanda and Burundi where women receiving prenatal care had increased chances of having their blood pressure checked,49 being given anti-tetanus vaccination49 and being treated according to the national and international guidelines.10 47 PBF studies in other settings have also described enhanced communication between providers and their catchment communities; in Rwanda and Burundi, providers worked with community health workers and community leaders to disseminate health education on the benefits of receiving maternal care in facilities,10 and in those settings utilisation rates increased which allowed facilities to attain their bonuses.10

However, success in terms of conveying the importance of care-seeking for maternal care and HIV care was accompanied by several negative, unintended effects in our study and others.50 51 While providers worked to address quantity and quality indicators in the SSDI-PBI programme, women and community leaders reported unpleasant scenarios in the context of the programme that—paradoxically—re-affirmed community-held reservations and hesitations about accessing facility-based care. In the absence of a more rigorous prospective study focussed specifically on ANC content, it is not possible to determine if (a) the programme worsened the situation in facilities thereby sparking disappointment or (b) the programme maintained the status quo in facilities yet heightened community expectations thus inducing disappointment or (c) the programme improved the status quo in facilities yet heightened community expectations thus inducing disappointment. For example, in this study, women reported disappointment because they attended facilities earlier during antenatal period, but only had their abdomen palpated. It is likely that this approach could have been routine prior to SSDI-PBI, but the intervention-raised women's expectations of what to expect during an early ANC visit, which then led to disappointment.

The negative side effects highlighted in this study largely reflect challenges that arise when a demand for services increases without concordant increases in facility-based infrastructure, human resources and medical supplies. Several studies have demonstrated that PBF programs place formidable strain on facility-based employees in terms of workload,16 24 50 52 which was highly salient in this study.

Beyond experiences amid overworked personnel, we also found that well-intended facets of the SSDI-PBI intervention appear to have generated unintended, negative effects even when providers were adequately responding to an incentive with the ‘right’ behaviour.53 The manner in which a well-intentioned indicator (here, couples testing for HIV during ANC) can spark resentment among women and intra-household marital strife generally was illuminating and echoed in related maternal health literature in Malawi.54 Another study related to a PBF intervention in Burkina Faso also highlighted unintended negative effects; that study found that the process of community verification (a vital component of PBF requiring investigators from the community to verify that provider-reported services had been performed) inadvertently led to marital strife because respondents found it inappropriate for male verifiers to engage in private conversations with women—including those who had attended PBF clinics for maternal care.24 Equally illuminating in our study is the finding that referrals to higher-level facilities for childbirth can ultimately—and paradoxically—lead to home delivery. In this study context, facility-provided referral transport was often lacking and women did not have the means to secure their own transport. This situation speaks to a broader body of recent PBF literature that question whether such a massive, health systems overhaul is appropriate and feasible in low- and middle-income contexts.29 55

The evidence on the emergence of unintended consequences reported in this study and in other studies from sub-SaharanAfrica19 24 56 57 partially resonates what has been documented earlier in high-income settings, such as the UK, where pay-for-performance systems have at times been observed to yield a negative impact on non-incentivised indicators.58–60 In addition to the difference that exists between pay-for-performance in high-income versus low-income system, we ought to note that the existing literature from high-income settings defines unintended consequences very specifically in relation to effects on non-incentivised clinical indicators and relies exclusively on quantitative methods. Our work instead, purposely relies on qualitative methods of data collection and analysis to allow a more open exploration of the issue at stake, looking for unintended consequences beyond clinical practice alone. In doing so, our work, similarly to the work of Turcotte-Tremblay et al,20 24 situates itself somewhat apart from the currently available literature on high-income settings and becomes propositive of a new and more open way of approaching the study of unintended consequences, which could find applications also in high-income settings.

As a limitation, we highlight that experiences or attitudes presented by respondents cannot be exclusively and wholly attributed to SSDI-PBI. Issues such as disrespect and abuse have emerged forcefully in recent literature within the Malawi context,61 similar settings62 and the region more generally.63 This study was cross-sectional. A longer, prospective study would more strongly allow researchers to link effects of given programme to intervention at hand. This study reports on perceptions and does not give quantifiable data in terms of changes, comparing case and control facilities. Finally, this study would have been strengthened by drawing in perspectives of providers regarding how the programme was operationalised and to what effect.

Conclusion

As an alternative purchasing mechanism to input-based financing, PBF programs such as SSDI-PBI hold potential, but also represent a tremendous endeavour in oftentimes weak health systems. This is especially true when PBF is not introduced within the framework of clear ministerial governance as only one out of a set of reforms and implemented in conjunction with other health financing measures targeting collection and pooling functions. This qualitative study examined the benefits, drawbacks and unintended effects of SSDI-PBI, a PBF intervention in Malawi. Our study found that community leaders and women themselves made efforts to facilitate success in reaching indicators related to skilled birth attendance and proper management of maternal risk factors across health facilities. However, these inputs were not enough to overcome formidable structural and social barriers.
