Qualitative evaluation of a guideline supporting shared decision making for extreme preterm birth.

Background and objectives: The decision to attempt resuscitation or provide palliative care at birth for extremely preterm infants between 22 and 25 weeks remains complex. The purpose of this study was to identify facilitators and barriers to implementation of a clinical practice guideline developed to support shared decision-making for these cases.Methods: A purposeful sample of healthcare providers, involved in the care of one of five cases of anticipated extremely preterm birth, was recruited for interviews. Participants shared their views on the guideline content, implementation process, and facilitators and barriers encountered. Interviews were audio-recorded and transcribed verbatim. Qualitative content analysis was used to code, categorize, and thematically describe the data. The Knowledge-Attitudes-Behaviours framework was used to organize the findings.Results: Twenty-five key informants (16 physicians, nine nurses) were interviewed. Participants described varying levels of knowledge of the guideline. Facilitators to implementation included: (1) an awareness of, familiarity with and belief in the content; (2) hard copy and electronic guideline accessibility; and, (3) institutional expertise to provide necessary care. Barriers included: (1) minimal awareness or familiarity with the content; (2) lack of agreement with the recommendations; (3) inadequate evidence and applicability to support changes in practice; and, (4) lack of resources to care for the most immature infants.Conclusions: Identified facilitators and barriers will inform the development of tailored strategies for improved local and future broader implementation. Other institutions can use the results to facilitate implementation of their guidelines on this ethically charged area.

Shared decision making during antenatal counselling for anticipated extremely preterm birth.

OBJECTIVES: To explore health care providers' (HCPs) perceptions of using shared decision making (SDM) and to identify facilitators of and barriers to its use with families facing the anticipated birth of an extremely preterm infant at 22+0 to 25+6 weeks gestational age. STUDY DESIGN: Qualitative descriptive study design: we conducted interviews with 25 HCPs involved in five cases at a tertiary care centre and completed qualitative content analysis of their responses. RESULTS: Nine facilitators and 16 barriers were identified. Facilitators included: a correct understanding of this process and how to apply it, a belief that parents should be the decision makers in these situations, and a positive outlook toward using SDM during antenatal counselling. Barriers included: HCPs' misunderstandings of how and when to apply SDM during antenatal counselling, challenges using the process for cases at the lower end of the gestational age range, fear of the negative emotions and stress parents face when making decisions, and HCPs' uncertainty about their ability to properly apply SDM. CONCLUSIONS: This study identified facilitators and barriers to use of SDM during antenatal counselling for anticipated birth of extremely preterm infants that can be used to inform development of tailored strategies to facilitate future implementation of shared decision making in this area.

Age Influences Microglial Activation After Cuprizone-Induced Demyelination.

Multiple sclerosis (MS) is a chronic inflammatory CNS disease, which causes demyelinated lesions and damages white and gray matter regions. Aging is a significant factor in the progression of MS, and microglia, the immune cells of the CNS tissue, play an important role in all disease stages. During aging, microglia are functionally altered. These age-related changes probably already begin early and might influence the progression of CNS pathologies. The aim of the present study was to investigate whether microglia in the middle-aged CNS already react differently to demyelination. For this purpose, several microglia markers (ionized calcium binding adaptor molecule 1 (Iba-1), P2RY12, F4/80, CD68, major histocompatibility complex II (MHCII), macrophage receptor with collagenous structure (Marco), Translocator protein 18 kD (TSPO), CD206, and CD163) were analyzed in the acute cuprizone demyelination model in young (2-month-old) and middle-aged (10-month-old) mice. In addition, microglial proliferation was quantified using double-labeling with proliferating cell nuclear antigen (PCNA) and bromodeoxyuridine (BrdU), which was injected with the onset of remyelination. To compare age-related microglial changes during de- and remyelination in both gray and white matter, the hilus of the dorsal hippocampal dentate gyrus (DG) and the splenium of the corpus callosum (CC) were analyzed in parallel. Age-related changes in microglia of healthy controls were more pronounced in the analyzed gray matter region (higher levels of F4/80 and Marco as well as lower expression of CD68 in middle-aged mice). During de- and remyelination, a stronger increase of the microglial markers Iba-1, CD68 and TSPO was observed in the splenium of the younger groups. There was a significant reduction of P2RY12 during demyelination, however, this was age- and region-dependent. The induction of the anti-inflammatory markers CD206 and CD163 was stronger in the middle-aged group, but also differed between the two analyzed regions. De- and remyelination led to a significant increase in PCNA+ microglia only in young groups within the white matter region. The number of BrdU+ microglia was not changed during de- or remyelination. These results clearly show that microglia are already altered during middle-age and also react differently to CNS demyelination, however, this is highly region-dependent.
