The initial search resulted in 322 articles, after Reviewer 1 screened Title & Abstract for the inclusion criteria and excluded any papers that did not address MMRCs, did not address maternal mortality, or were not based in the US, 28 papers remained. A full-text review of those 28 papers resulted in the exclusion of 12 articles that did not include recommendations for MMRCs. The 16 articles that met the inclusion criteria were then reviewed for recommendations.
Eight recommendations for improving, supporting, and organizing MMRCs were identified from the content analysis (Table 2). The most commonly endorsed themes were: 1) establishing multidisciplinary and representative MMRCs, 2) improving data quality and management standards, and 3) performing in-depth reviews of pregnancy-related deaths to identify preventable deaths. Additional themes raised included: creating clear legislative mandates for MMRCs to review and address maternal mortality, establishment of a national MMRC, establishing a funding structure and resource supports for MMRC work, incorporating a health equity framework into the analysis of pregnancy-related deaths, and ensuring rural representation on boards in states with rural populations.

Multidisciplinary and Representative MMRC
The most mentioned theme, identified as a priority by 11 of the 16 articles in this analysis, was the composition of the MMRC. Table 3 lays out the specific professions indicated by the authors in their articles. These professions varied in terms of their training in medicine, their training in social and behavioral health, their focus on population health, their role in healthcare delivery systems, and their role in patient representation and advocacy. Nine of the 11 articles endorsed the importance of public health experts on the MMRC. There was also wide agreement on the importance of having doctors and nurses on the board, though the specific disciplines differed across papers. The importance of mental and behavioral health professionals was endorsed by five papers, though again the specific recommended disciplines varied across papers. The inclusion of health administrators, hospital associations, or insurance providers were also mentioned by five papers. Together these recommendations represent attention to the inclusion of professionals with an understanding of maternal mortality in terms of patient-level, clinic-level, community-level, and system-level factors that can be addressed and prevented.

Legislative Mandate for MMRC Reviews
Two papers acknowledged the need for a legislative mandate to codify and support state-wide MMRCs. [13, 14] Lindsay et al., 2017 [13] reflected on their experience re-establishing an MMRC in Georgia. They identified a problem where some MMRC members were unable to gain access to relevant case information and therefore were thwarted in their effort to review cases of maternal mortality. Therefore, they recommend the establishment of legal protections for members in MMRCs from civil and criminal liabilities, establishing MMRC member legal authority to review cases, and protocols for data collection such as those included in the Maternal Mortality Bill: Georgia Senate Bill 273. [13] Shellhaas et al., 2019 [14] recommend legislative and statutory protection to guide and support MMRCs in data collection, reporting, and review processes. Furthermore, the authors called for increasing legislative support in establishing MMRCs and passage of federal legislation to support MMRCs. [14] They further emphasized the need to increase legislative support in establishing MMRCs and passage of federal legislation to support all MMRCs in providing direction for data collection, review processes, and reporting. [13,14]
Data Quality and Management
Several recommendations to address the concerns about data quality and management arose from the reviewed papers. Data for MMRCs can be drawn from a variety of sources, including vital records, medical records related to birth, fetal death certificates, autopsy and coroner reports, social service records, health insurance records, and law enforcement records. [12, 15] One of the issues raised was misidentification of pregnancy-related deaths that can be addressed by accurately recording data in the death certificate and refining the methodology being used. [15] Papers asserted different recommendations for how to accurately record and standardize data.
Three of the papers [14, 16, 17] specifically recommend use of the Maternal Mortality Review Information Application (MMRIA) that allows access to and sharing of data across participating MMRCs in the United States. The MMRIA is a standardized data collection tool and data repository run by the CDC that facilitates MMRC investigations into maternal deaths. [16]
An additional suggestion endorsed [17] is the use of a checklist protocol to ensure easy access to data by authorized parties of MMRCs. These checklist tools help in maintaining confidentiality, protection of data, and determining the specific cause of pregnancy-related death. [17, 18]
In-Depth Review of Pregnancy-Related Deaths
Four of the papers [14, 16, 18, 19] recommended in-depth review of preventable maternal deaths by the MMRC. The primary concern of the authors here is that some of the factors that lead to maternal deaths such as suicide, drug overdose, and violence, are not typically included in MMRC analyses but are relevant causes of maternal mortality. Therefore, in addition to focusing on obstetric and clinical causes of maternal deaths, the authors argue it is important to structure the review process and the use of preliminary data of MMRCs to identify the exact causes of maternal deaths as well as to determine preventability. In addition, Anderson et al [16] further emphasized the need to create a standardized process for disseminating review information and follow-up across all MMRCs. Shellhaas et al [14] and Main EK (2012) [18] each reiterated the importance of MMRCs answering the six review questions delineated in Table 1.
Establish a National MMRC
Two papers Zaharatos et al [20] and Clark et al [21] went further than recommending federal legislation to support MMRCs and instead recommended the creation of a national MMRC. They recommend the establishment of a national MMRC, reasoning that the incidence of maternal mortality in any single state is fairly low, and therefore the ability to identify trends and patterns is hampered by limited statistical evidence. However, they argue, at a national level, the incidence of maternal death is high enough to allow analyses that can identify common risk factors and predictive variables in which we can intervene to prevent maternal death.
By contrast, some articles mentioned that the state based MMRC could often get a more detailed and nuanced picture of the characteristics of the health system and population in the state, allowing for a more sensitive analysis of the causes and preventability of maternal deaths. While not explicitly recommending state only MMRCs, it is worthwhile to note that there is not universal agreement on the benefits of a national MMRC.
Funding and Resource Support for MMRCs
Two articles (Anderson et al [16] and Kozhimannil et al [22]) recommend increasing and codifying funding for MMRCs. These funds are intended to support the ongoing work of the MMRC including hiring support staff members. This can also support the time MMRC members spend conducting thorough reviews of maternal death, potentially improving the thoroughness of each review. Kozhimannil et al [22] specifically discussed funding and resources as essential for supporting maternal mortality review and action across rural states in the United States.
Rural Representation on MMRCs
While many papers endorsed specific professions that ought to be included on the MMRC, Kozhimannil et al [22] identified geographic representation as an important factor to consider in states with heavy rural populations. Specifically, the authors recommend the establishment of MMRCs in states with rural areas to identify the gaps related to geographical coverage of quality services and the inclusion of rural representatives on MMRCs in states with substantial rural populations. [22] They recognize that despite the increasing establishment of MMRCs, lack of development and support for MMRCs in heavily rural states as well as lack of attention to rural communities in states with existing MMRCs have limited the ability of MMRCs to see and respond to the circumstances that contribute to maternal mortality in rural populations. [22] They note that pregnancy-related complications and death are highly prevalent in rural areas, and therefore rural inclusion and representation on MMRCs is important to consider.
Incorporation of a Health Equity Framework and SDoH
Kramer et al [ 23] recommend the incorporation of a health equity framework within MMRCs to provide a contextual framework for pregnancy-related deaths that are related to social determinants of health and are frequently not included within existing MMRC review protocols. The health equity framework helps to identify underlying community-based factors related to racial and geographical inequity that contribute to or cause maternal mortality.[23] They argue that addressing maternal mortality effectively must include attention to social determinants of health that are infrequently treated as causes of death.[23]
