Evidence, Guidelines, and Best Practice in Midwifery

Evidence-based midwifery integrates the best available research evidence with the midwife's expertise and the woman's values and preferences. Clinical guidelines translate that evidence into recommendations, and best practice involves applying them judiciously while respecting individual circumstances and the physiology of normal childbirth.

Definition

Evidence-based midwifery is the conscientious use of current best research evidence, together with clinical expertise and women's values, to inform decisions about maternal and newborn care; guidelines are systematically developed statements that help translate evidence into practice.

Scope

This topic describes the principles of evidence-based practice in midwifery, the role and limits of clinical guidelines, the appraisal of evidence, and the aim of providing care that is neither too little nor too much. It is a reference description and does not itself constitute clinical guidance or recommend specific interventions for individuals.

Core questions

• What does evidence-based practice mean in the context of midwifery?
• How are clinical guidelines developed and how should they be used and adapted?
• How can care avoid both under-use and over-use of interventions?

Key concepts

• Evidence-based practice
• Hierarchy of evidence
• Clinical guidelines and recommendations
• Critical appraisal
• Shared decision-making
• Appropriate use of intervention
• Translation of evidence into practice

Mechanisms

Evidence-based practice combines three elements: best available evidence, clinical expertise, and the woman's values, as articulated in the foundational account of evidence-based medicine (Sackett et al., 1996). Systematic reviews synthesize studies into pooled estimates that inform guidelines, which then offer graded recommendations; midwives apply these alongside clinical judgement, recognizing that guidelines inform but do not replace individualized assessment.

Clinical relevance

Using evidence and guidelines helps maternity care align with what research shows to be effective and safe while respecting normal physiology and women's preferences. Reviews highlight the goal of well-matched care that avoids both delayed or absent intervention and unnecessary medicalization (Miller et al., 2016). This entry describes how evidence informs practice and does not prescribe interventions for any individual.

Evidence & guidelines

Foundational accounts define evidence-based practice as the integration of research, expertise, and values (Sackett et al., 1996); systematic reviews such as that on midwife-led continuity models provide high-level evidence for organizing care (Sandall et al., 2016); maternity-quality reviews frame the balance between under- and over-intervention (Miller et al., 2016); and bodies such as the WHO issue statements and guidelines, for example on caesarean section rates, to guide appropriate practice (Betran et al., 2015).

Debates

How should guidelines be balanced against individualized, woman-centred care?

Guidelines summarize population-level evidence, but rigid application can conflict with a woman's circumstances and preferences; best practice uses guidelines as a starting point while preserving clinical judgement and shared decision-making.

Frequently asked questions

What are the three components of evidence-based practice?

Best available research evidence, the clinician's expertise, and the values and preferences of the woman, integrated together to inform care decisions.

Do clinical guidelines override a midwife's judgement?

No; guidelines summarize population-level evidence and inform decisions, but they are applied alongside clinical judgement and the individual woman's circumstances and preferences.
