Internationally, patient safety (PS) has become a major concern in healthcare  . A focus on person-centred care, patient participation and PS strategies is of the utmost importance. PS is defined as the prevention of errors associated with healthcare, thereby, constituting an essential component of quality care  . The WHO  designed an implementation guide to improve the quality of care provided to women giving birth. Learning about adverse events and near-misses is essential for enhancing maternity and obstetric care  . A recently published re- view reveals that effective communication and learning from adverse events are important. Healthcare professionals’ and patients’ perspectives on ethical conflicts, blame and responsibility, medication errors, lack of trust and involvement should be explored  . This is in accordance with the WHO  recommendation that PS should focus on the use of quality improvement methods. Many latent and active factors at individual and system level interact to cause PS incidents. Therefore, an integrated approach to PS is necessary for maintaining qua- lity of care. Person-centred care has been advocated as a way to improve PS  . Patient involvement is essential for ensuring safety. Levels of engagement can improve the relationship between healthcare professionals, patients and families in the context of person-centred care, for example, shared decision-making   and self-management  . Research on person-centred care and related concepts such as person-centredness  , patient-centred care  , patient-close care and patient focus has grown rapidly  , in different contexts, e.g., mental health  , medical wards  and obstetric care  . Systematic development of a PS culture is necessary because inadequate quality of care leads to human suffering  . In their qualitative study of midwifery staff perceptions of safety culture, Currie and Richens  argue that all staff members should be given the authority to report accidents, incidents, near-misses and safety concerns. In addition, the importance of communication between healthcare providers  , improving relationships between patients and professionals   as well as continuity of care  is described in several studies.
The role of patients in their own safety has been explored in a recent review  . The results revealed that existing evidence was related to medication rather than patients’ capability and willingness to be involved. An investigation of the patient’s role in terms of her/his rights is recommended  . Despite these recommendations, patients are not receiving appropriate care. Therefore, to improve the field of maternity and obstetric care, a better understanding of the strategies to reduce health risks should be developed.
There is some evidence that person-centred care may impact positively on patient satisfaction  . When defining person-centred nursing McCormack and McCance  (p. 472) presented four constructs: prerequisites, which concern the attributes of the nurse; the care environment, which means the context in which care is delivered; person-centred processes, which focus on delivering care through a range of activities; and expected outcomes, which are the results of effective person-centred nursing.
Starfield  reported that patient-centred care generally refers to interaction during visits and that the benefits may be episode oriented with focus on the management of diseases, especially comorbidity and the use of coding systems that reflect professionally defined conditions. In her research Starfield  states that patient-centred care should be complemented with person-centred care. However, some negative aspects have been reported in relation to nurses’ views of the restructuring of healthcare, as it was found that it changed their professional roles and disrupted their relationships with patients and colleagues  .
According to the Cochrane Collaboration literature, there are no accepted definitions of patient-centred care  . A concept analysis of patient-centred care revealed several attributes: holistic, individualized, respectful and empowering  . These authors stated that based on empirical evidence, the benefits of patient-centred care are improved quality of care, increased satisfaction with healthcare and enhanced health outcomes. A narrative review and synthesis revealed that the three core elements of patient-centred care are patient participation and involvement, the relationship between the patient and the healthcare professional, and the context in which the care is provided  . The review comprised 60 papers related to health policy, medical, and nursing literature. These components are of interest because our intention is to explore the linkages between PS and person-centred care in the maternity and obstetric care context. The present study is a part of a larger international research project on Patient Safety in Obstetric and Maternity Care, which is theoretically based on the WHO    recommendations.
The aim of the review was to evaluate the current state of knowledge pertaining to PS and its link to person-centred care. The review question was: What is the evidence of the relationship between PS and person-centred care in the maternity and obstetric context?
2. Search Methods
2.2. Search Strategy and Search Terms
Searches were conducted in online databases (CINAHL, Academic Search Premier, Webb of Science, Maternity and Infant Care, Ovid Nursing and ProQuest) from 2005 to 2016. We searched for articles that included (Major Heading (MH) “Patient Safety+”) or “patient safety” and (MH “Patient Centred Care”) or “patient centred care” or “people-centred health services” or “people-centred healthcare” or “people-centred health services” and (MH “Obstetric Care+”) or “obstetrical care” or “maternal health services” or (MH “Nurse-Midwifery Service”) or (MH “Midwifery+”) or “midwifery”. We also searched peer reviewed articles for (MH “Patient Safety+”), and (“Patient*” or “Person*” or “People N2cent*”) and (“matern*” or “obstetr*” or “pregnan*” or “childbirth*”). In the third search we combined the above with “Communication+” or “communication” or (MH “Leader- ship”) or (MH “Feedback”) or (MH “Collaboration”).
2.3. Inclusion and Exclusion Criteria
We included articles that met the following criteria: original research studies with a qualitative and/or quantitative design, published in English language as well as a maternity and obstetric context. We required articles to specifically use the term “patient safety” and excluded those that did not. Likewise, due to the range of overlapping definitions of person-centred care we only selected articles that referred to person-centred care or similar, such as patient-centred care. Studies were excluded that did not include the maternity care context. Guidance statements, review articles, educational development and study protocols were also excluded. However, the reviews that were of interest in relation to our aim were read and included in the Introduction and Discussion. This constitutes the second stage of the integrative review  (p. 1).
2.4. Search Outcome
An overview of the included studies is presented in Table 1.
2.5. Quality Appraisal
The quality appraisal was conducted by applying the Critical Appraisal Skills Programme (CASP)  , tools to determine the validity and reliability of the studies, as well as the relevance of each study to our review question. The CASP Cohort Study Checklist was used to assess the quality of the quantitative studies, while the CASP Qualitative Checklist was employed to assess the qualitative studies. For mixed-methods studies both qualitative and quantitative components of the study checklists were used. To describe the quality of evidence we used the following terms: “high quality” i.e., few limitations, “moderate quality” i.e., some criteria not met, and the “low quality”, indicating serious limitations with only a few or no criteria being met or failure to adequately address the criteria. We did not use a checklist for the theoretical studies. Elliott and Thompson’s  descriptions of quantitative research appreciation were employed to assess the methodological quality of the individual studies. Differences in scores were resolved by discussion, thus no study was excluded due to low quality.
We adapted the template presented by Long and Godfrey  to assess the quality of the empirical and theoretical studies. The rationale for choosing this template was that we were not only interested in whether the study was of high quality, but also wanted to understand whether the findings were relevant to the maternity and obstetric care context, thereby maximizing our understanding of the contextual meanings. The data from the articles were extracted by the first author (E.S.). In the third stage, four components were focused on: 1) the phenomenon studied: core elements of PS, 2) design/methodology, data collection, analysis and sample, 3) context: setting in which the care was delivered, core theoretical elements of person-centred care (or its variants, such as patient-centredness, patient-close care or patient focus, midwifery-led care, women-centred care) and 4) policy and practice implications. Each of the included articles was reviewed and evaluated independently by three of the authors. Finally, two of the authors independently appraised the Tables illustrating the results. Table 2 presents the fourth stage, i.e., data analysis of the integrative literature review process  (p. 1).
We were interested in the linkages between culture and context. The thematic ana- lysis was followed by a process of interpretation, i.e., the fifth stage leading to the

overall main theme, key aspects or domains, as well as sub-themes  (p. 1). The selected articles were compared, grouped and qualitatively summarized in relation to the review question. The five authors read the articles, extracted terms or descriptions and validated the first draft Table 2. The interpretation of aspects of PS was based on the theoretical view of PS presented by the WHO    . For interpretation of components of the contexts we used the core elements of patient-centred care; patient participation and involvement, the relationship between the patient and healthcare professional, and the context in which care is provided  (p. 4).
3.1. Search Results
3.2. Summary of Quality Assessment
The designs comprised mixed-methods    , a cross-sectional survey    , a cohort study (prospective, i.e., implying the forward direction of the research question and retrospective, i.e., meaning that when the study is planned, all or part of the data have already been collected    , a qualitative descriptive study  , review of documents, i.e., a theoretical approach   as well as an intervention case study  Table 1. The information about selection bias was unclear in terms of the representativeness of the population. Some studies failed to report confounding factors related to recruitment or analysis. Two studies were document analyses of files pertaining to medical errors or adverse events, outcomes and closed claims   .
Only two studies addressed the appropriateness of the sample size. One study had a very low response rate  . Most of the studies used correlational, regression statistical analyses and descriptive statisticsas well as χ2 tests  . The study by Iida et al.  used the Pearson correlational coefficient to examine the relationship between variables and applied a multiple regression analysis to compare women’s perception of women-centred care and their satisfaction with care during pregnancy. Convergent validity of the scale scores was measured by correlations with external teamwork related items  . The study by Wagner et al.  used logistic regression. In summary, the most common weaknesses of the included studies related to design, sampling and analysis. The quality of each relevant study is reported in Table 2.

3.3. Evidence Related to Key Components of Long and Godfrey’s Evaluation Criteria
Criterion No.1: the core elements of PS. All articles reporting presented PS presented patient safety culture aspects, thereby contributing to knowledge and understanding of the problems inherent in practice. Criterion No.2: design/methodo- logy, data collection, analysis and sample are described in Table 1. Criterion No.3; context: setting in which the care was delivered, core theoretical elements of person-centred care. The context/settings presented were primary care midwifery practices  , hospital labour and delivery units       , and an obstetric ward  . The core theoretical elements of person-centred care were midwifery-led care   , women-centred care  , safety culture theory  , a multicomponent model including evidence-based protocols, team training, foetal monitoring simulation and an educational programme   , patient-centred communication  , a collaborative model  , and a multidisciplinary team approach  . Two studies focused on the relationship between the structure, process and outcome of care with reference to Donabedian’s paradigm  and a respectful approach, good, and careful communication and safe boundaries  . The third area centred on the sampling strategy adopted Table 1. The samples varied between 22 - 4700 subjects. In some studies, “Why were these informants or events chosen?” To answer the research question was not explicitly reported nor was the relevance of key events to the study aims.
Criterion No.4, policy and practice implications, the outcome criteria informing the study i.e., “What counts as ‘success’ or a beneficial effect?” It was possible to interpret guidelines for patient risk assessment  , to improve PS multicomponent safety initiatives in the healthcare system   , enhance approaches to communication  , share experiences by debriefing  , team training  , standardized documentation  and analysis of claim files to identify opportunities for improvement  . In summary, the perspectives of patients     and professionals      , were addressed. The quality total score of each relevant study is reported in Table 2. Overall, we found a range of research designs employing qualitative and quantitative approaches. They were rated as high (n = 6), moderate in quality (n = 1) and low quality (n = 2).
The selected articles described the core elements of PS, with emphasis on medical, technical and caring aspects. The person-centred care models are determined by the quality of interactions between the patient, family members and healthcare professionals, in addition to communication skills, shared understanding, decision making and emotional support. The contextual aspects of maternity and obstetric care interact with various intervention strategy components to improve PS and are enhanced by competence outcomes and the linkages to person-cen- tred care.
3.4. Evidence of the Linkages between Patient Safety and Person-Centred Care in Maternity and Obstetric Care
One theme was revealed: Trustful, safe communication in the relationship between the patient, family members and healthcare professionals. Two domains; Safety culture and Multidisciplinary capacity building, emerged in the results. There were six dimensions related to the first domain, namely: Values, beliefs and trust, Respectful communication, Sense of control of labour and birth, Patient involvement, Sharing experiences and Continuity of care, while the second domain, was based on the following five dimensions: Collaborative work, Knowledge sharing, Teamwork, networking and accountability, Coordination and risk management and Patient-centred communication Table 3.
Domain 1: All included studies reported aspects of Safety culture. The study by Martijn et al.  presented evidence that availability, patient risk assessment and communication were problematic domains. Cultural aspects such as values, beliefs and trust in the relationship between the patient and healthcare professionals were reported    . Respectful communication was described in three studies    . The sub-theme sense of control of labour and birth was found in four studies     . Patient involvement was included in the theme of safety culture in six studies       . Eight of the studies highlighted the importance of sharing experiences         while one also mentioned continuity of care  .
Domain 2: The theme Multidisciplinary capacity building was based on the results from all included studies. This theme consisted of five sub-themes, all related to multidisciplinary work: Collaborative work      , Knowledge sharing   Teamwork, Networking and Accountability    
Table 3. The synthesis of linkages between patient safety and person-centred care.
  . Factors related to the healthcare organization, and leadership were Coordination and Risk Management        and finally, Patient-centred Communication was interpreted as involving Capacity Building      .
There are few studies on the theoretical and clinical importance of understanding the relationship between PS and person-centred care. To address this gap we developed an integrative review to evaluate the current state of the evidence. Findings from this review advance our knowledge and have significant theoretical and clinical implications. The key feature of PS and person-centred care in the maternity and obstetric context is trustful safe communication in the relationship between the patient, family members and healthcare professionals, based on two domains; Safety culture comprising six dimensions and Multidisciplinary capacity building consisting on five dimensions.
Series of propositions regarding the pattern of linkages between PS and person-centred care were identified from the selected papers, which can inform clinical assessment and interventions as they highlight the fact that communication and/or miscommunication may pose a risk to PS in the maternity and obstetric context. Similar to previous empirical studies of PS  , this review provides strong evidence of the need for good communication between healthcare professionals and patient. If the communication process does not include the sharing of meaningful information, it may result in poor quality, uncertainty and conflict. Notably, these findings expand previous research by presenting two perspectives of PS and person-centred care, namely safety culture and multidisciplinary capacity building. The clinical implications of the findings are therefore noteworthy. The main component in the safety culture domain is respectful communication, where the sharing of experiences leads to a sense of control during labour and birth as it relates to the women’s sense of personal capacity. According to Yu et al.  , other prerequisites for PS are patient involvement and continuity of care, which prevent errors. Thus, the second major finding was that the midwives’ communication competences are essential due to the necessity of interacting with patients to support the birth and meet the women’s needs and expectations. This is confirmed by the study by Renfrew et al.  that highlights respect, communication, knowledge and understanding for facilitating care that is tailored to women’s circumstances and needs. The third major finding was that collaborative teamwork, coordination and risk management, knowledge sharing and patient-centred communication constitute an important part of the multidisciplinary capacity building domain. This finding is consistent with the WHO’s  , PS theory comprising five domains: Leadership and management, Patient and public involvement, Safe evidence-based clinical practices, Safe environment and Lifelong learning.
Not surprisingly, communication appears in both domains. However, the two dimensions differ in that patient-centred communication can be interpreted as a professional attitude on the part of midwives that includes sharing information and incident reporting. This is in line with Mendes and Ventura’s  research on verbal and non-verbal communication, the ability to listen and interpret feedback, in addition to awareness of safety issues. The systematic review by Ward and Armitage  emphasizes the patient’s voice as a key element of PS development and management.
Despite the necessity of involving patients in their own safety, the efforts to promote involvement are not focused upon. The relationship between the birth environment and midwifery practice should be explored with focus on a safe and satisfying birth. Foureur et al.  suggest studying the impact of design on communication in maternity care settings and developing a conceptual model based on the literature and understanding of design, communication, stress and care models. This is an innovative starting point for a deeper understanding of the complexity of birth and the range of disciplines necessary for safe and effective maternity care. In line with the theory of PS, person-centred care may improve quality and shared decision-making by transforming and developing decision- making through the engagement model  to improve health outcomes, suggesting that a new patient-centred implementation model is required. This framework focusing on the core components of evidence-based decision making through the engagement model links PS and person-centred care and has the potential to go beyond maternity care and influence other clinical areas. Central to this model is the women’s active involvement in decision-making  . The findings from this review are in line Lyndon et al.  , who demonstrated that effective multiprofessional communication in maternity care is respectful, clear, direct, and explicit. The Lyndon et al.  highlighted of the importance of improving communication by building it on an infrastructure of respect, attentiveness, collaboration, and competence, which is in agreement with our findings.
Our findings demonstrate the need for improved communication processes in the area of care planning. Quality and safety are informed by women’s experiences  Different levels of engagement can be discussed in relation to the importance of communication: in direct care, i.e., the relationship between healthcare professionals, patients and families; on the organizational level to enable patients and their family members to influence the way the organization provides care; and in community healthcare to make it possible for patients and their family members to influence the health or healthcare strategies of public agencies  .
Overall, this review contributes novel and important knowledge that deepens the understanding of how an organization functions or fails. It also highlights the need for system change  , arguing that to change our behaviour within a system, we have to change the way we think about the system per se, the way knowledge is created and how we become involved in the process of knowledge translation  (p. 226). The Safety Model described by Macchi et al.  is based on the anticipation of undesired events and measures to ensure safe functioning. The emphasis of the non-linear model’s emphasis on the organization and its dynamics calls into question linear causal thinking to explain accidents, while supporting the normal functioning of the organization in combination with the prevention of incidents and accidents. Processes to develop PS are implemented across the organization and take the organization’s characteristics into account, such as communicating advice to protect against risks and for organizational development  . The safe management systems are embedded in the organization’s culture. Entwistle and Watt  (p. 36) emphasize that person-centred care can be understood in terms of a single guiding idea that involves recognizing and cultivating patients’ personal capabilities. Despite the differences between the definitions and characterizations, person-centred care can be related to the broad overarching ethical idea that patients should be “treated as persons”  (p. 29). The authors suggest the capability approach as a guiding idea, including behaviours such as respect, compassion, responsiveness to subjective experiences, and support for autonomy, thus, the intrinsic value of person-centred care. This approach constitutes a broad normative framework for the evaluation and assessment of individual well-being  .
Qualitatively enhancing the understanding of a phenomenon by illuminating its meanings may lead to healthcare professionals adopting a more holistic approach to care. An integrated team and the way team members work together will influence communication about safety. Finally, directly involving team members in person-centred care will facilitate safe care.
4.2. Limitations of This Review, and Suggestions for Future Research
This review makes valuable and unique contributions to deepening the understanding of the links between PS and person-centred care. However, the findings should be interpreted in the light of some limitations. CASP  was the assessment tool used for quality appraisal of observational analytic (cohort, cross sectional and case-control)  studies and also for the qualitative appraisal as well. As suggested by Long and Godfrey  (p. 184), we adapted some parts of the evaluation tool to assess the quality of the studies and reflect the uniqueness of the associated paradigm Table 1 and Table 2. When developing their evaluation tool the authors focused on the following questions: The conceptual or theoretical framework: i.e., “In what way does this study contribute to knowledge theory and/or practice?”, the contextual aspects related to the setting in which the study was undertaken, i.e., “Why this setting?”, “Is it appropriate in order to examine the research question?” and “Is sufficient detail provided about the setting?”, the nature of the sampling strategy adopted, i.e., “Why were these informants or events chosen?” and “Are key events appropriate given the study aims?”, and finally the outcome criteria i.e., “What counts as ‘success’ or has a beneficial effect and over which time periods?” In the synthesis of the findings the reviewers were cautious when extracting the domains and dimensions from the empirical and theoretical studies. Interpretative methods were used to synthesize and integrate the findings. Essential components of the linkages between PS and person-centred care were identified. The concept of person-centred care is used interchangeably with patient-centred care, although they could vary slightly and thereby provide different information that we might have missed. However, the authors are experienced in several areas of nursing practice and have numerous years of research experience in the contexts of nursing, midwifery, and public health and health sciences. In addition, they collaborated closely and discussed the quality and the content of the findings. A further limitation is that the quality appraisal or assessment tools used are dependent on the study design and not all questions were relevant to the individual studies. In addition, the authors’ understanding of research design and critique as well as knowledge of the difficulty involved in interpreting the design employed should be taken into account. Further empirical research is needed to understand the linkages between PS and person-centred care.
We conclude that there are several linkages between PS and person-centred care in the maternity and obstetric context. Healthcare professionals have an important role in delivering safe person-centred care and require knowledge, leadership, academic supervision, mentorship and financial resources to maintain quality of care and PS.
