Interdisciplinary Care Approach for Perinatal Patients in Acute Care Settings: Clinical Effectiveness, Cost-Effectiveness, and Guidelines

CADTH Rapid Response Report: Summary with Critical Appraisal

and .

Context and Policy Issues

Interdisciplinary care is referred to in the literature as an efficient way to provide optimal healthcare services to various population groups, including in the area of perinatal and newborn care.14 Although many definitions exist, interdisciplinary care typically involves at least two healthcare professionals of different backgrounds sharing their knowledge and skills in order to set and achieve common objectives for a patient.1,2 The collaborative process requires enhanced communication between service providers, as well as mutual trust and respect in order to share responsibilities.1,2

Interdisciplinary care has been the topic of several CADTH Rapid Response Reports; however, none of these reports evaluated collaborative models of care in a perinatal population of pregnant individuals and newborn infants. According to the World Health Organization, the perinatal period ranges from 22 weeks of pregnancy to 7 days after birth.5 In Canada, there are organizations for whom enhancing interdisciplinary collaboration is recognized as a priority in order to improve the quality and sustainability of healthcare services for parents and infants throughout the perinatal period.1 Assessing the evidence regarding the use of interdisciplinary care for perinatal patients will support evidence-based practice decisions to improve health outcomes in these patients.

The purpose of this report is to review the clinical effectiveness, cost-effectiveness, and evidence-based guidelines regarding the use of interdisciplinary care for perinatal patients in acute care settings.

Research Questions

  1. What is the clinical effectiveness regarding the use of interdisciplinary care for perinatal patients in acute care settings?
  2. What is the cost-effectiveness regarding the use of interdisciplinary care for perinatal patients in acute care settings?
  3. What are the evidence based-guidelines for using interdisciplinary care for perinatal patients in acute care settings?

Key Findings

Two relevant studies regarding the clinical effectiveness of interdisciplinary care for perinatal patients in the acute care setting were included: one non-randomized prospective cohort study6 and one retrospective, uncontrolled single-group before-and-after study.7 No relevant cost-effectiveness evaluations, or evidence-based guidelines, were identified.

Overall, findings from the included studies suggested that a model of interdisciplinary care for perinatal patients that includes a dedicated obstetrician collaborating with midwifery care may be associated with a decrease in the percentage of individuals undergoing induction of labour and primary cesarean sections. This collaborative model may also be associated with an increase in the percentage of vaginal births after cesarean delivery.

Uncertainty surrounds these conclusions, as they are drawn from observational studies that may provide lower quality evidence than other study designs. Changes in best clinical practices or patient preferences throughout the study duration, as well as changes in the care model other than interdisciplinary collaboration, may have influenced the findings.

Evidence regarding optimal healthcare services for pregnant individuals and infants during the perinatal period of labour, delivery, and days following birth suggests a potential benefit of using interdisciplinary collaboration of healthcare professionals to improve health outcomes in these patients. High quality clinical and cost-effectiveness research would reduce uncertainty surrounding the true impact of this change in care model on the quality and sustainability of healthcare services. In addition, evidence-based guidelines are needed to indicate the types of collaboration and professional disciplines that would provide optimal benefits for parents and their newborn children.

Methods

Literature Search Methods

A limited literature search was conducted on key resources including PubMed, CINAHL, The Cochrane Library, University of York Centre for Reviews and Dissemination (CRD) databases, Canadian and major international health technology agencies, as well as a focused Internet search. Methodological filters were not applied to limit the retrieval by study type. Where possible, retrieval was limited to the human population. The search was also limited to English language documents published between January 1, 2014 and May 9, 2019.

Selection Criteria and Methods

One reviewer screened citations and selected studies. In the first level of screening, titles and abstracts were reviewed and potentially relevant articles were retrieved and assessed for inclusion. The final selection of full-text articles was based on the inclusion criteria presented in Table 1.

Table 1. Selection Criteria.

Selection Criteria.

Exclusion Criteria

Articles were excluded if they did not meet the selection criteria outlined in Table 1, they were duplicate publications, or were published prior to 2014. Guidelines that were not evidence-based (i.e. for which the recommendations were not based on a systematic approach to identify and evaluate the supporting evidence) or with unclear methodology were also excluded, as well as position statements and consensus documents that did not describe a formal literature search for evidence upon which the recommendations were based. A list of articles identified from the literature search that did not meet the inclusion criteria is provided in Appendix 5 as additional references of potential interest.

Critical Appraisal of Individual Studies

The included non-randomized cohort study and the single-group before-and-after study were critically appraised using the Risk of Bias Assessment Tool for Non-randomized Studies (RoBANS).8 A review of the strengths and limitations of each included study were described narratively.

Summary of Evidence

Quantity of Research Available

A total of 602 citations were identified in the literature search. Following screening of titles and abstracts, 582 citations were excluded and 20 potentially relevant reports from the electronic search were retrieved for full-text review. No potentially relevant publications were retrieved from the grey literature search for full text review. Of these potentially relevant articles, 18 publications were excluded for various reasons, and 2 publications met the inclusion criteria and were included in this report. These comprised one non-randomized prospective cohort study and one retrospective uncontrolled single-group before-and-after study. Appendix 1 presents the PRISMA9 flowchart of the study selection. Additional references of potential interest are provided in Appendix 5.

Summary of Study Characteristics

A summary of the characteristics of the included clinical studies is provided below. Additional details are available in Appendix 2, Table 2.

Study Design

Two clinical studies were included. Rosenstein et al. 20156 was a non-randomized prospective cohort study and Krolikowski-Ulmer et al. 20187 was a retrospective, uncontrolled single-group before-and-after study.

Country of Origin

The primary authors of the two studies (Rosenstein et al. 20156 and Krolikowski-Ulmer et al. 20187) were from the United States.

Patient Population

One study (Rosenstein et al. 20156) included privately insured patients delivering at a community hospital between 2005 and 2014. Publicly insured patients delivering at the same hospital over the same period of time served as a non-equivalent control group due to the fact that they were already offered a collaborative approach from the beginning of the study and therefore, did not undergo any change in care model. The study included 4,884 deliveries (3,413 of these were before the collaborative model was implemented and 1,471 were afterwards). A total of 2,406 participants (49%) were privately insured and as such, were part of the group that experienced a change in care model. The second study (Krolikowski-Ulmer et al. 20187) included patients admitted to the obstetrics ward of a mid-sized midwestern medical center. No population characteristics were reported.

Interventions

The two studies (Rosenstein et al. 20156 and Krolikowski-Ulmer et al. 20187) evaluated the impact of a collaborative care model that included a labourist and midwifery care. A labourist was generally defined in the studies as a dedicated obstetrician providing labour and delivery management for the obstetrics ward with no or limited competing clinical duties.6,7

Outcomes

Cesarean births as well as vaginal births after cesarean delivery were major clinical outcomes included in both studies. Cesarean births were reported as primary cesarean sections in low-risk nulliparous individuals, and/or as a total number of cesarean sections performed (primary and repeat). Other reported outcomes included induction of labour and composite of short-term adverse neonatal outcomes, which was defined as a 5-minute APGAR < 7, an umbilical artery pH < 7.0 and an umbilical artery base excess > 12. Details regarding the outcome measures used are provided in Appendix 2.

Summary of Critical Appraisal

Additional details regarding the strengths and limitations of the included publications are provided in Appendix 3, Table 3.

Rosenstein et al. 20156 was a non-randomized prospective cohort study and Krolikowski-Ulmer et al. 20187 was a retrospective, uncontrolled single-group before-and-after study. Both studies included all patients admitted to the obstetrics ward and delivering at their respective medical center. Data was collected from medical records, a trustworthy source, in a single study center where the majority of healthcare professionals were likely to remain stable throughout the study duration, minimizing potential differences in the way that the routine healthcare services were provided over time. The clinical outcomes included in both studies were objective and assessed by healthcare professionals attending the delivery. Each publication reported results for all major clinical outcomes included in the studies.

Both studies (Rosenstein et al. 20156 and Krolikowski-Ulmer et al. 20187), although relatively well conducted, presented some limitations. More specifically, the non-randomized prospective cohort study (Rosenstein et al. 20156) had a risk of selection bias. The characteristics of privately insured patients differed before and after exposure to the change in care model. A statistically significantly higher proportion of individuals experienced diabetes and hypertension during the period that followed the change in care model compared with the preceding period. In addition, the privately and publicly insured individuals were not comparable population groups as they differed in several of their patient characteristics. However, several relevant characteristics were identified and accounted for in the statistical analysis. The other publication reporting results from a retrospective, uncontrolled single-group before-and-after study (Krolikowski-Ulmer et al. 20187) had insufficient reporting of patient characteristics that precluded assessment of whether the population groups were similar before and after exposure to the change in care model.

Confounders were also a significant issue in both studies. Confounders are factors that may significantly affect the outcome of an observational study by affecting the potential cause and effect relationship of an intervention.8 Before and after differences related to the time elapsed, such as changes in clinical practices or patient preferences throughout the study duration, could not be excluded in both studies and may have influenced the findings. One example is that the authors of Krolikowski-Ulmer et al. 20187 reported that the study’s medical center ceased all early-term inductions and cesarean sections following the release of the 2013 American College of Obstetricians and Gynecologists guidelines, which is likely to have some impact on the findings.

The change in care model may also be associated with confounders. In Rosenstein et al. 2015,6 multifactorial changes in the care model included the increased availability of an obstetrician, in addition to the implementation of collaborative care, as patients went from being attended by a private practice physician to a collaboration between a labourist and midwifery care. Although the collaborative care model became available for all privately insured patients, authors reported that the midwifery service attended to a maximum of 42% of the vaginal births among those who were privately insured. This limits exposure to interdisciplinary care and suggests that the increased availability of an obstetrician alone may have had an impact on the findings. In Krolikowski-Ulmer et al. 20187 however, the change in care model was related to the interdisciplinary approach, as patients went from being attended by a labourist only, to a collaboration between a labourist and a certified nurse midwife.

Finally, the patient population was representative of those delivering at the medical centers where the studies were performed. Findings were necessarily affected by the healthcare professionals best practice preferences and by local hospital policies. Therefore, generalizability of the findings to other patient populations is uncertain.

Summary of Findings

A detailed summary of study findings is available in Appendix 4, Table 4.

Clinical Effectiveness of Interdisciplinary Care for Maternal and Perinatal Patients

Cesarean Births

Two clinical studies evaluated the impact of a collaborative care model that included a labourist and midwifery care. A labourist was generally defined in the studies as a dedicated obstetrician providing labour and delivery management for the obstetrics ward with no or limited competing clinical duties.6,7

Results from one non-randomized prospective cohort study (Rosenstein et al. 20156) showed a statistically significant decrease in the percentage of pregnant individuals undergoing primary cesarean sections among privately insured patients who experienced a change from private practice to a collaborative care model. No statistically significant difference was observed in cesarean births in those who were publicly insured delivering at the same hospital over the same period of time. These patients were already offered a collaborative approach from the beginning of the study and therefore, did not undergo any change in care model.

Results from one retrospective, uncontrolled single-group before-and-after study (Krolikowski-Ulmer et al. 20187) did not show significant differences in the percentage of pregnant individuals undergoing cesarean sections (primary or total cesarean delivery) between the time period when a labourist only model was in place and after the implementation of a collaborative care model.

Vaginal Births after Cesarean Delivery

Results from one non-randomized prospective cohort study (Rosenstein et al. 20156) showed a statistically significant increase in the percentage of vaginal births after cesarean delivery among privately insured patients who underwent a prior cesarean section between the private practice period and the collaborative care model period. No statistically significant difference was observed in vaginal births after cesarean delivery in those who were publicly insured delivering at the same hospital over the same period of time. These patients were already offered a collaborative approach from the beginning of the study and therefore, did not undergo any change in care model.

Results from one retrospective, uncontrolled single-group before-and-after study (Krolikowski-Ulmer et al. 20187) did not show significant differences in the percentage of vaginal births after cesarean delivery between the labourist only time period and after the implementation of a collaborative care model.

Induction of Labour

Results from one retrospective, uncontrolled single-group before-and-after study (Krolikowski-Ulmer et al. 20187) showed a statistically significant decrease in the percentage of individuals undergoing induction of labour between the labourist only time period and after the implementation of a collaborative care model.

Composite of Short-Term Adverse Neonatal Outcomes

One non-randomized prospective cohort study (Rosenstein et al. 20156) evaluated a composite of short-term adverse neonatal outcomes, which was defined as a 5-minute APGAR < 7, an umbilical artery pH < 7.0 and an umbilical artery base excess > 12. Results did not show significant differences between the two time periods evaluated in both privately and publicly insured patients. However, the study did not have sufficient power to demonstrate statistical significance for testing of this outcome.

Cost-Effectiveness of Interdisciplinary Care for Maternal and Perinatal Patients

No article regarding the cost-effectiveness of interdisciplinary care for maternal and perinatal patients in acute care settings was identified; therefore, no summary can be provided.

Evidence-Based Guidelines Regarding Interdisciplinary Care for Maternal and Perinatal Patients

No relevant evidence-based guidelines regarding the use of interdisciplinary care for maternal and perinatal patients in acute care settings were identified; therefore, no summary can be provided.

Limitations

This Rapid Response report identified a limited number of relevant studies for inclusion. These were observational studies that may provide lower quality evidence than other study designs such as randomized controlled trials. Therefore, findings should be interpreted with caution.

There was no or limited evidence for various clinical outcomes such as length of hospital stay, neonatal intensive care unit admissions, or perinatal harms outcomes in pregnant individuals and newborn infants.

No Canadian studies were identified. Generalizability of the findings from the included studies to the Canadian population of perinatal patients is uncertain and may vary according to the healthcare professionals best practice preferences and local hospital policies.

Conclusions and Implications for Decision or Policy Making

Two relevant studies regarding the clinical effectiveness of interdisciplinary care for perinatal patients in the acute care setting were included: one non-randomized prospective cohort study6 and one retrospective, uncontrolled single-group before-and-after study.7 No relevant cost-effectiveness evaluations, or evidence-based guidelines, were identified.

Overall, findings from the included studies suggested that a model of interdisciplinary care for perinatal patients that includes a dedicated obstetrician collaborating with midwifery care may be associated with a decrease in the percentage of individuals undergoing induction of labour and primary cesarean sections. This collaborative model may also be associated with an increase in the percentage of vaginal births after cesarean delivery. However, uncertainty surrounds these conclusions, as they are drawn from observational studies that may provide lower quality evidence than other study designs. In addition, confounders were identified that may impact the cause and effect relationship of the interdisciplinary care approach. Changes in best clinical practices or patient preferences throughout the study duration, as well as changes in the care model other than interdisciplinary collaboration, may have influenced the findings.

Evidence regarding optimal healthcare services for pregnant individuals and infants during the perinatal period of labour, delivery and days following birth suggests a potential benefit of using interdisciplinary collaboration of healthcare professionals to improve health outcomes in these patients. High quality clinical and cost-effectiveness research would reduce uncertainty surrounding the true impact of this change in care model on the quality and sustainability of healthcare services. In addition, evidence-based guidelines are needed to indicate the types of collaboration and professional disciplines that would provide optimal benefits for parents and their newborn children.
