Effectiveness of respectful care policies for women using routine intrapartum services: a systematic review

Background Several studies have identified how mistreatment during labour and childbirth can act as a barrier to the use of health facilities. Despite general agreement that respectful maternity care (RMC) is a fundamental human right, and an important component of quality intrapartum care that every pregnant woman should receive, the effectiveness of proposed policies remains uncertain. We performed a systematic review to assess the effectiveness of introducing RMC policies into health facilities providing intrapartum services. Methods We included randomized and non-randomized controlled studies evaluating the effectiveness of introducing RMC policies into health facilities. We searched PubMed, CINAHL, LILACS, AJOL, WHO RHL, and Popline, along with ongoing trials registers (ISRCT register, ICTRP register), and the White Ribbon Respectful Maternity Care Repository. Included studies were assessed for risk of bias. Certainty of evidence was assessed using GRADE criteria. Findings Five studies were included. All were undertaken in Africa (Kenya, Tanzania, Sudan, South Africa), and involved a range of components. Two were cluster RCTs, and three were before/after studies. In total, over 8000 women were included at baseline and over 7500 at the endpoints. Moderate certainty evidence suggested that RMC interventions increases women’s experiences of respectful care (one cRCT, approx. 3000 participants; adjusted odds ratio (aOR) 3.44, 95% CI 2.45–4.84); two observational studies also reported positive changes. Reports of good quality care increased. Experiences of disrespectful or abusive care, and, specifically, physical abuse, were reduced. Low certainty evidence indicated fewer accounts of non-dignified care, lack of privacy, verbal abuse, neglect and abandonment with RMC interventions, but no difference in satisfaction rates. Other than low certainty evidence of reduced episiotomy rates, there were no data on the pre-specified clinical outcomes. Conclusion Multi-component RMC policies appear to reduce women’s overall experiences of disrespect and abuse, and some components of this experience. However, the sustainability of the demonstrated effect over time is unclear, and the elements of the programmes that have most effect have not been examined. While the tested RMC policies show promising results, there is a need for rigorous research to refine the optimum approach to deliver and achieve RMC in all settings.


Plain English summary
There have been increasing reports that some women who use health facilities for childbirth experience disrespectful or even abusive care. This may be due to an increase in incidence, or to an increase in recognition. Policies to increase respectful maternity care (RMC) may, in theory, improve women's experiences, and health outcomes, but this has not yet been demonstrated in formal studies. We looked for research studies that compared the introduction of RMC policies with the usual way of doing maternity care in that setting. We included papers in any language, and any year, listed in six databases, as well as looking at registers of on-going studies. Five studies met our inclusion criteria.
All took place in Africa. All were published between 2007 and 2017. Two were cluster-randomized trials, and three were before/after studies.
Using criteria to assess our certainty in the results of each study ('GRADE' criteria), we were moderately certain about findings that the policies increased women's experiences of good quality care and of respectful care, and that they reduced physical abuse and disrespectful or abusive behaviours by staff. Evidence of reductions in nondignified care, lack of privacy, verbal abuse, neglect and abandonment was of low certainty. There did not appear to be any difference in reports of satisfaction, but this finding was also of low certainty. The only clinical outcome reported was episiotomy rates, which were reduced, but, again, this finding was of low certainty.
We concluded that policies with multiple components to increase RMC do seem to work, by reducing women's experiences of disrespect and abuse overall, as well as reducing some components of this experience. Policies and further research to increase RMC in different settings are recommended.

Background
The requirement to uphold, protect, and fulfill human rights obligations at all levels of government, society, and health and maternity care systems is clear [1]. Despite this, there have been rising levels of reports of disrespect and abuse in maternity care, and, specifically, in institutional settings [2][3][4][5]. This may be due to an increase in incidence, or to an increase in recognition. Women's experiences of such treatment has been linked to reduced use of maternity care provision, [3,4,6,7], and may lead them to discourage other women from seeking care [6]. In some countries, experiences of non-consented invasive procedures occurring routinely during birth (termed 'obstetric' violence, but perpetrated by a range of care providers) have resulted in legislative changes designed to marginalize and eliminate such practices [8].
It is widely acknowledged at the policy level that all women should have the right to respectful, dignified care during labour and childbirth [9]. Promoting respectful maternal care (RMC) has been recognized as an important component of strategies to improve utilization and quality of maternity care [10].
In response to awareness of the overt abuse of women and neonates in some maternity care settings, and to the obligations to protect, respect and uphold human rights, initiatives have been enacted at all levels in some settings, from the legislature, to the direct interface between childbearing women and neonates, and caregivers. As an example of how the agenda has changed over the last 10 years, the White Ribbon Alliance have shifted from a focus on maternal mortality as a clinical phenomenon that requires structural solutions (increased skilled birth attendance, institutional births, and access to emergency obstetric care, for instance), to framing policies and practices to reduce maternal deaths within a more nuanced approach, that includes a Respectful Maternity Care Charter alongside existing responses [11]. In 2014, the WHO published a statement calling for the elimination of disrespect and abuse during facilitybased childbirth [12]. As a consequence of this focus, in 2016 the WHO prioritized a question for its 2018 intrapartum care guideline on the effects of polices to increase RMC [13].
Policies and initiatives in this broad area tend to be framed in three different (though sometimes overlapping) categories: 'humanised' care' , 'respectful' care, and care based on human rights. Studies of humanised care often focus on the reduction of unnecessary, unconsented interventions, and increasing midwifery care [14]. Care based on human rights principles is focused more upstream, at access issues, or equity concerns [15]. In contrast to both of these approaches, respectful maternity care is more centrally focused on staff values, attitudes, and behaviors, as a vehicle for changing disrespectful and abusive practices in encounters with women and their families [11]. Interventions can be experienced as either positive or negative, but disrespectful and/or abusive staff attitudes and behaviours are likely to lead to traumatic experiences [16].
Audits and evaluations of RMC initiatives designed to change adverse attitudes and behaviours are promising [17]. Given the growing attention on this area, and the need for effective implementation strategies, it is now very timely to establish what works in this area, and to identify the important knowledge gaps that still remain. This paper reports on the effectiveness review undertaken during the WHO's recent intrapartum care guideline development process to assess the current state of knowledge in this area as the basis for the guideline recommendation [13]. The aim of this review was, therefore, to establish the effectiveness of the introduction of a policy of RMC versus usual care with no RMC policy for women using routine intrapartum services.

Review methods
We conducted this review in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and followed a protocol (available from the authors).

Types of studies
Randomized and non-randomized controlled studies evaluating the effectiveness of introducing RMC policies into health facilities were considered for inclusion. Inclusion and exclusion criteria are given in Table 1.

Types of participants
The review included interventions that had been applied broadly across a service and/or local community to improve RMC for all women, rather than interventions that were specifically tailored to address the needs of particular groups of women. Although women from marginalized groups (and their families) in all settings are more likely to be subject to disrespectful and/or abusive attitudes and behaviours from staff [18], policies designed to improve RMC for all women are likely to have the greatest impact on those who are currently most exposed to adverse attitudes and behaviours.
There is a growing interest in respectful care for the newborn. This is an important area of concern, but it was not addressed in the current review, as the focus was on healthy women using facilities for intrapartum care.

Types of interventions
Studies on interventions to increase RMC for women defined as staff attitudes and behaviours that respect women's basic dignity, privacy, and autonomy, the right to consent, and the right not to be exposed to verbal or physical abuse, neglect, or detention, were included.
Although the review focuses on the immediate experience of respectful or disrespectful care as a result of staff attitudes and/or behaviours, the review team recognize that the factors precipitating such behaviours may include health system failures, including gender inequalities, bullying hierarchies, and lack of pay, resources, and development opportunities.

Types of outcomes
The outcomes that were most likely to be improved by an effective RMC policy were agreed by the Steering Group, and the Guideline Development Group for the WHO intrapartum care guideline. These outcomes are set out in Table 2. This review is focused on quantitative data. A parallel review was also undertaken for the guideline reports on qualitative findings in this area [19].

Search strategy Databases and other sources
PubMed, CINAHL, Lilacs, AJOL, WHO RHL, and Popline were searched, along with ongoing trials registers (ISRCT register, ICTRP register), and the White Ribbon Respectful Maternity Care Repository (that collects items relevant to respectful care or disrespect and abuse from around the world, including audits, service evaluations, and formal research). We also included regular AMDD monthly RMC updates, as they were issued.
Zetoc alerts were set up for relevant journal contents pages as they were published.
References for all papers reviewed at the full text stage were backchained to ensure that no earlier relevant studies had been missed. Controlled studies in any language or conducted at any date were included when: • The intervention was primarily or partially designed to increase respectful care/decrease D&A (overall, and/or the following components; privacy/dignity/non-consented care/verbal abuse/ physical abuse/abandonment/detention) • The intervention was designed to impact on the intrapartum period • The participants included women using standard intrapartum care • Studies included a control group of any kind (RCTs, case-control or case-matched, observational longitudinal pre-post)

Exclusion criteria
Uncontrolled studies and studies where the following was the primary focus were excluded, unless respectful care was explicitly stated to be the mechanism of effect for the change: • The intervention is primarily designed to decrease specific intrapartum interventions • Studies designed primarily to increase the right to access to, or equity in, maternity care • Studies designed to improve one specific aspect of care (such as companionship or communication) Policies designed to increase respectful care or its components for specific sub-groups of women using intrapartum care specifically tailored to their needs

Search terms
The terminology in this subject area is not always captured in MeSH terms, and some of the databases (for example Lilacs and AJOL) require keyword searches rather than complex Boolean chains. The searches were therefore modified to take account of these constraints. The approach was to use simple search strings to generate large numbers of hits, and then to screen the hits carefully to check for inclusion.
The searches were all carried out between July 26th and 28th 2017. Table 3 provides the search terms used by database, and the resulting hits. All searches were undertaken by SD. Inclusion was agreed by SD, KF, and OTO by consensus.

Quality assessment
Risk of bias assessment for each study was undertaken using the Cochrane Risk of Bias tool [20]. The grading of the certainty of evidence was agreed by consensus between two authors (SD and TAL).

Analysis
There was considerable heterogeneity in the methods applied by available studies on this topic as they did not use standard outcomes to measure respectful care or its components. Data were therefore not pooled or summarized, but reported descriptively, using the measures as reported by the primary study authors. GRADE criteria were applied to indicate the degree of certainty in the findings for each outcome assessed [21]. The assessment was based on consensus between two authors (SD and TAL).
All the included studies were undertaken in Africa (Kenya, Tanzania (2), Sudan, South Africa). The publication date range was 2007-2017. Two were cluster RCTs (c-RCTs) [22,23], (one with only two sites, and one with 10 sites), and three were before/after studies (four reports) [24][25][26][27]. The risk of bias assessment of all included studies revealed problems with allocation concealment, and, in most studies, with use of selfreport measures alone (though this was appropriate for the outcomes that depend on women's accounts of their views and experiences). Only one study [23] reported undertaking an a priori power calculation, though most used statistical techniques to correct findings for possible known biasing factors. Reasons for the risk of bias judgments for each study are given in Table 5.
The types of components included in the intervention packages were highly heterogeneous. They included training in values and attitudes transformation; communication skills training; setting up quality improvement teams; disrespect and abuse monitoring; staff mentorship; improving privacy in wards (for example, with curtains or partitions between beds); improving staff conditions (for example, by providing tea for those on-shift); maternity open days; community workshops; mediation/alternative dispute resolution; counseling community members who have experienced disrespect and abuse; making provision for complaints; and educating women on their rights. One intervention was focused on companionship in labour, with an emphasis on empathic, respectful care [22], and one was focused on a communication-building package with staff [27]. The characteristics of usual care were not reported in any of the studies.

Study participants in all included studies were women utilizing facilities for intrapartum care. The total number of women involved across all included studies was around 8000 at baseline, and around 7500 at follow up (these were usually not the same women). In terms of staff, only two studies included data [24,27], resulting in a total of 170 interviews at baseline, and 160 at follow up. Some of these were likely to be the same respondents at both time points.
All the studies reported on aspects of disrespectful or respectful maternity care. In all studies, this included women's self-report; however, in two studies [24,26] data were also obtained from researcher observation of practice. Apart from findings on rates of episiotomy from one paper [22] none of the other studies assessed the pre-stated clinical outcomes. Data from the included studies were not pooled due to differences in the study design and in how the outcomes were defined and reported across studies. Because data on most outcomes were relatively sparse and all of the studies were at unclear or high risk of bias, the certainty of findings was downgraded.

Findings
The findings are reported in three broad groups: Positive birth experiences, experience of mistreatment, and clinical outcomes.

Positive birth experiences
We found moderate certainty evidence that implementation of a policy of RMC is more likely to result in women reporting that the care they received was respectful (one cRCT, approx. 3000 participants (exact numbers not stated); adjusted odds ratio (aOR) 3.44, 95% CI 2.45-4.84) [23]; two observational studies, one reporting a change from 0% to 22.8% 'excellent' respectful care, and the other from 89.7% to 94.7% of women reporting experiences of respectful care in the post-and preintervention groups, respectively [25,27].
This was reflected in accounts of good quality care overall (one cRCT, approx. 3000 participants; aOR 6.19, 95% CI 4.29-8.94) [23], and in observational studies, but not in the proportion of women reporting being very satisfied with care, though this latter finding is based on low certainty evidence (one cRCT; aOR 0.98, 95% CI 0.91-1.06) [23], and one observational study (satisfaction 75.8% in the RMC group and 12.9% in the control group) [25].   Post-intervention: 'Every second woman registering at the facility for delivery was selected for observation'. 'Women who had attended an Open BirthDay (OBD) session were selected for observation'. Total observations = 459. Structured community interviews 4-6 weeks postpartum, based on 'systematic' selection from the OBD register and those directly observed (n = 149). All providers and administrators were interviewed (55/76, 72%). Intervention: a three-part step-wise dissemination and participatory process with local stakeholders from the facility, district community, and national representatives, and a multistakeholder working group. Two components were developed.  Intervention; an educational intervention to promote childbirth companions to improve clinical outcomes and quality of care and promote a more woman-friendly service. Introduced to the 5 randomised sites in the two months subsequent to the introduction of the WHO RHL facilities (see below). It included an interactive workbook for use in a workshop, and the workshop itself; posters and banners encouraging women to bring in a companion; illustrated pamphlets for staff and pregnant women to show how companionship could be promoted locally; a magazine style video on birth companionship including interviews with recent South African mothers and with staff. Encouragement by the research team for senior staff to attend the workshop. The research team ran the workshop. Visits by the research team every two weeks to discuss progress, and how to overcome obstacles. Control group: usual care plus: All 10 sites were given access to the WHO Reproductive Health Library, computer hardware, and training to promote evidence based information (over two months in 1999). The 5 control hospitals were also given an evidence based intervention to promote external cephalic version, including a lecture, group discussion, a video demonstration, and an invitation to attend training in ECV Risk of bias assessment: Lack of allocation concealment, selfreport outcome measures only Abbreviations: D&Adisrespect and abuse; RCTrandomized controlled trial; CScaesarean section  This study showed a reduction in episiotomy at follow up (mean rate of 21% at RMC sites vs 39% at control sites; P = 0.02)

Notes on grading of Risk of Bias All of the observational studies were assessed as having 'serious risk' of bias, due to lack of allocation concealment and blinding, lack of randomization, and use of self-report measures for some or all outcomes. Both cluster-RCTs were also assessed as having 'serious risk' of bias, due to lack of allocation concealment and blinding, and use of self-report measures for some outcomes. The RCTs were only downgraded one level for these issues as the nature of the intervention usually involved staff and/or service users in active participation, so they could not be blinded to allocation, and self-report is the only way of assessing if women experienced their care as respectful or not. Blinding of data collectors/analysts was not discussed in any of the included studies 1 Assessment of risk of bias: All of the observational studies were assessed as having 'serious risk' of bias, due to lack of allocation concealment and blinding, lack of randomization, and use of self-report measures for some or all outcomes. Both cluster-RCTs were also assessed as having 'serious risk' of bias, due to lack of allocation concealment and blinding, and use of self-report measures for some outcomes

Experience of mistreatment
One c-RCT [23] and two before/after studies (reported in three papers) [24][25][26] presented overall measures of any mistreatment or abuse. The resulting moderate certainty evidence from the cluster-RCT suggests that RMC probably reduces experiences of disrespectful or abusive care by about two-thirds (approx. 3000 participants; aOR 0.34, 95% CI 0.21-0.57). Observational data from the other two studies are consistent with the cRCT, with an estimated 40% relative reduction in any disrespectful or abusive care after the RMC policy introduction in one study (aOR of 0.6; 95% CI 0.4-0.8; absolute rates of 20.1% vs 13.2%) and an absolute 52% reduction in another, from 70% to 18%).
In terms of specific attitudes and behaviours, moderate certainty evidence from four studies (2 c-RCTs and 2 before/after studies) suggests that RMC policies probably reduce physical abuse. One c-RCT [22] reported a reduction in physical abuse in the intervention arm from a baseline average of 2% to 1% at follow-up and an increase in the control arm from a baseline average of 3% to 4% over the same time period (number of participants was not stated). The other c-RCT (approx. 3000 participants) reported an aOR of 0.22 (95% CI 0.05-0.97) [23]. One before/after study found that observed physical abuse reduced from 3.5% before the RMC intervention (677 participants) to 0.4% afterwards (523 participants) [26] and the other reported a reduction in observed use of fundal pressure from 3.4% before (208 participants) to 0.2% after (459 participants), and in 'episiotomy without anesthesia' of 4.3% before to 0% after [27].
Evidence on other components of disrespectful care were all graded low certainty, including evidence suggesting a reduction in non-dignified care (1 cRCT, approx. 3000 women; aOR 0.58, 95% 0.30-1.12) [23]. This cRCT evidence is supported by a before/after study that found large reductions in various aspects of nondignified care (such as the provider not introducing herself to the mother, failure to provide a clean bed for the mother, and mother not being cleaned after birth) [24]. Findings from four studies (2 cluster-RCTs, and 2 before/after studies) suggest that RMC interventions may reduce neglect and abandonment: one cluster-RCT found a 64% reduction (approx. 3000 participants; aOR 0.36, 95% CI 0.19-0.71) [23], the other cluster-RCT reported an increase from 12% to 16%, while the observational studies found no clear difference.
Low-certainty evidence based on three studies (1 cluster-RCT, and 2 before/after study) was also contradictory for effects on verbal abuse. The estimates of effect in two studies included the possibility of increase, while the third study showed an absolute reduction of 49%. Similar uncertainty limits the findings on lack of privacy in one cRCT [23] and two before/after studies [24][25][26]. Various measures and inconsistent findings were reported, especially when the effects were measured over time.
Evidence on non-consented care and detention (keeping women at the facility against their will) was of very low certainty, with the two included studies showing effects in opposite directions.

Clinical outcomes
Episiotomy was reported in one small study [22] and the findings suggest that RMC interventions may reduce episiotomy by an average 13% (from 34% to 21%) in the RMC policy arm of this study and an average 1% (from 40% to 39%) in the control arm. However, this was graded as low-certainty evidence. The review found no evidence on mode of birth, length of labour, maternal use of pain relief, perinatal hypoxia-ischaemia or perinatal mortality.

Discussion
Data from the five studies that met our inclusion criteria suggested that, with moderate certainty, multi-component RMC policies could increase women's experiences of good quality care and of respectful care, and reduce experiences of disrespectful or abusive behaviours by staff, and of physical abuse. The evidence on reductions non-dignified care, lack of privacy, verbal abuse, neglect and abandonment, and reduction in episiotomy rates was less certain. There did not appear to be any difference in reports of satisfaction, but this finding was also graded as low certainty.
To date, there appear to be few well-designed, adequately powered controlled studies that have examined the impact of a policy for increasing RMC, either as a single component or package of measures, for women during labour and childbirth. Given that recognition of the nature and prevalence of disrespectful maternity care is relatively recent, this is probably not surprising. Our review is limited by the relatively high risk of bias in the included studies, partly due to the fact that only two were randomized trials, one of which included only two sites, and many of the pre-specified outcomes were not captured in these studies. The data also only represent one region of the world, and the interventions under comparison were highly heterogeneous. It was surprising that no studies were located from regions of the world other than Africa. It is possible that intervention studies in this area are framed differently (as, for example, 'humanised care'). As noted above, we decided not to include interventions using this terminology, as such studies tend to be focused on reducing specific interventions, or introducing specific models of care, like midwifery led schemes. This omission could be a limitation of the study. However, over 8000 women are included at baseline, and over 7500 at the endpoints, and the findings of the RCT's are generally reinforced by the observational data. It is uncommon to have so much data from low-resource settings, and the consistent direction of effect across most of the findings suggest that, even if the package of interventions varied, the multi-component design of the studies, targeted across whole health systems, was effective for at least some outcomes.
As in the analysis of survey data reported by Reis et al. [17], and the model of Jones et al. [28], the findings suggest that intervention programmes need to pay attention to the interconnectivity between the local community, the culture of the local institution, and the socio-cultural context in which both operate. Staff, as well as service users, can be affected by bullying, and disrespect [29]. This can include horizontal and vertical abuse at work and at home, especially in parallel with gender issues [30]. For staff to be enabled to enact respectful care, they must be in a system in which they, too, are respected, properly and promptly paid, able to do their job well, and where they have access to supplies, clean water, wellmaintained equipment, and the potential for updating and development.
Interventions that take account of the needs of the local community, staff, service users, and the service are expensive, difficult to control for, and require authentic commitment and buy in from managerial staff, funders, and local politicians. Often such interventions need time to become fully integrated, but this also means that staff turnover and political changes can remove the people and resources that were originally committed to support the project. Issues of long-term sustainability require prolonged engagement of those intending to implement change. Despite these complications, the studies included in this review do suggest that simple elements in a package of interventions across dynamic systems of maternity care could increase women's sense of respectful care, and of care quality, and could reduce incidences of disrespect and abuse (especially physical abuse, and high rates of episiotomy) on the basis of objective observation. The lack of effect on satisfaction is probably due to the fact that women's reports of being satisfied are often highly skewed toward the positive, and depend on their prior expectations [31].
Qualitative research on respectful care suggests that multiple components are more likely to be effective [19]. Taken as a whole, the interventions used in included studies suggest the need for a shift in values, attitudes and beliefs, and for consistent messages and support across the whole system of care, from the local community, to front line care providers (doctors, midwives, nurses), senior professional and managerial staff, and administrators. Components ranged from caring for the carers (including making sure staff had access to tea and toast in recognition of their inability to leave the ward during a shift due to workload) to the hosting of Respectful Care Workshops, and provision of mentorship, and dispute resolution.
To ensure that RMC policies can be maximally effective in the future, policymakers and maternity service funders should ensure that infrastructure deficiencies leading to disrespectful care (e.g. state or absence of toilets and washing facilities, lack of privacy, overcrowded birth spaces) are addressed. However, such improvements require resources and time, depending on existing infrastructure and resources, and this should not inhibit the promotion and progressive rapid realization of respectful, dignified, woman-centered care for all women in terms of day to day service provision, within the context of a human rights-based approach to reducing maternal mortality and morbidity [32]. As the drivers and types of mistreatment and abuse will vary across settings, these rapid implementation schemes should ensure that local factors are clearly identified through communication with women and women's groups in their setting/s. RMC interventions should then be tailored to addressing them among all stakeholders to optimize implementation.
Steps that can be taken very quickly at a strategic level include the development and integration of written, upto-date standards and benchmarks for RMC that clearly define goals, operational plans and monitoring mechanisms policymakers, in collaboration with local services and communities. This work should be initiated and supported by local policy makers and maternity service funders and providers, with local birth activist groups, where they exist. Protocols for RMC and accountability mechanisms for redress in the event of mistreatment or violations, and of informed consent procedures, should be reviewed regularly. Mechanisms should be put in place to ensure that all women, and particularly those from disadvantaged backgrounds, are made aware of their right to respectful, dignified maternity care and of the process they need to use address complaints. This process should be simple, easily located, and culturally normative. It could, for example include service development and audit mechanisms that integrate women's feedback, and ensures response to complaints.
Although the search strategy for this review did not explicitly include studies where respectful care policies were targeted at specific marginalized groups, RMC policies should recognize local contexts in which subgroups of women may be at particular risk of mistreatment, including those groups with special needs (e.g. poor awareness of their rights, and language difficulties), and ensure that RMC strategies increase levels of respectful care and equity for these women and families. Interest is also growing in the concept of respectful care for the newborn. Along with respectful care for family and friends of those using maternity services, this would be a valuable area for a review in future, as more intervention studies are published in these areas.
Policymakers should be aware that shifts in health system infrastructure, such as reorganization of staffing, or increasing workloads, could disrupt implementation. Any infrastructural changes need close monitoring to ensure and evaluate the feasibility and sustainability of RMC practices.
Current and new initiatives to implement respectful care should be formally evaluated, as a minimum with audit and/or service evaluation techniques, but ideally through controlled designs that can also allow for assessment of effects over time, such as stepped wedge designs, with or without internal action research cycles to take account of local conditions. New studies could also assess the best RMC indicators, in terms of validity and responsiveness in clinical settings, and optional implementation techniques in different kinds of settings. Ultimately, it would be important to assess the impact of increasing RMC on substantive maternal and perinatal birth outcomes, and on longer-term health and wellbeing.

Conclusion
Despite the relative paucity of evidence to date, this review indicates that implementing multi-factored policies and practices to increase respectful care can be successful in low resource settings. This requires a visible, sustained, and participatory intervention process, with committed facility leadership, management support, and staff engagement. It is still unclear precisely which elements of a package of RMC implementation might be most successful, and most sustained over time. However, it is important to move ahead rapidly with implementation to ensure that the human rights of women, families and newborns are not violated. Studies that incorporate flexible but rigorous controlled designs, such as stepwedge implementation research, or, at the basic level, audit and service evaluation, should be undertaken alongside a widespread implementation process. Documentation of successful RMC programmes can then inform the development of guidelines and protocols for better quality maternity care in different settings.
