Add central fetal monitoring and stir: Is this the solution to understaffing?

While the makers of central fetal monitoring technology don’t market their systems as a means to solve staffing issues, there is evidence in research that such systems are sometimes used in an attempt to maintain safety when staffing levels are not ideal. Smith and colleagues (2012) used the term “midwife by proxy” to describe the use of CTG monitoring as a substitute for midwifery care. In their literature review, they identified this issue being described in five of the eleven studies. While not explicitly stated in any of the research, it does appear that in more recent studies that it was central fetal monitoring systems that were being used as the “midwife by proxy”. For example, in one of the included studies, midwife Alice explained watching multiple CTGs from one location:

It was easier for me to sit down at the desk, and I watched because it was easier to do that . . . the CMM2 [senior clinical midwife manager] had to go and help assist with an FBS [fetal blood sample], and she said to me, “Would you mind looking after, watching Room 1 and 7 as well?” So, I was watching Room 1, 4, 7, and 9.

(Hill, 2016, p. 72)

In Alice’s situation, we see one midwife tasked with watching four women’s CTG recordings simultaneously. It is physically impossible for one person to respond in a timely and clinically appropriate way to more than one abnormal CTG at a time. There are also no guarantees that simply because a CTG is visible at the central fetal monitoring station that someone will be present in that area, nor that they will be attending to the CTG recording that requires attention.

One of the midwives I interviewed for my research told me about the challenge of escalating care when they interpreted the CTG as abnormal but the midwife at the central fetal monitoring station disagreed with their assessment:

I had come out of the room and asked them to assess my trace, and they looked at it [on the central monitor]. There were four or five traces on the board. I was concerned about my trace, but there was someone else who had a trace that was more concerning. They looked at my trace, saying no this is fine. . . . They didn’t consider the clinical context. It might be fine for a baby that is term, well grown, and got resilience, but not with a little pretermer.

(Small, et al., 2022, p. 196)

This was described as “not being able to see the wood for the trees”, because without specific knowledge of the birth woman and her clinical context, the CTG cannot be interpreted appropriately. While in this instance, the woman had a midwife who was actively advocating for her, if the woman’s midwife were absent from the picture due to short staffing, then there would have been a risk to safe care provision.

In her Master’s research thesis (Griggs, 2012), American labour and delivery nurse Kelly Griggs related the case of a woman whose baby developed irreversible neurological injury while continuous CTG recording on a central fetal monitoring system was in use. At several key points in time, the nurse caring for the woman had to leave the woman’s room to attend to the care of others as there were not enough staff. No one was at the central fetal monitoring station as all nurses were providing clinical care. Consequently, no one recognised the CTG was abnormal and appropriate action was not taken in a timely manner.

Because of this event, the hospital instituted a new position, the “perinatal safety nurse”. The perinatal safety nurse’s role was to remain at the central fetal monitoring station, constantly interpreting all CTGs, and communicating with other clinical staff to ensure timely responses when the pattern was abnormal. In her thesis, Griggs described improvements in several outcomes during the first two years of this initiative, highlighting the value of having someone in a dedicated perinatal safety role.

Griggs also approached staff at the unit to better understand what had changed in the unit after the introduction of the new role, finding that all was not as positive as it seemed from her maternal and perinatal data (Griggs & Woodard, 2019). Nurses completed surveys before and after the introduction of the new role; and were invited to attend focus groups once the new nursing role had been embedded in the organisation. The only statistically significant difference in the before and after surveys was a very concerning reduction in nurses’ confidence that they would be approached if someone had concerns about the CTG recording of a woman in their care. At both time points, nurses indicated low support for the statement that staffing levels were adequate to support the perinatal safety nurse role.

Griggs and Woodard explained that when the unit was busy (another way of saying there were not enough nurses to maintain safe care), the perinatal safety nurse was “often pulled away from their station” to assist with other nursing cares (p. 275). The task of watching the CTGs then fell to nurses from the senior management team who observed from a remote location. While not commented on in the paper, this raises concerns for me about further loss of contextual information, competing demands on the nurse’s attention, and diminished ability to mount a timely response.

So – what happens when you introduce a central fetal monitoring system into a maternity service who are struggling to provide adequate staffing to maintain safety? You end up with a central fetal monitoring system in a maternity service that still struggles to provide adequate staffing to maintain safety. Along with this, you now have a large hole in the budget that might have been directed to hiring staff. You cannot fix an unsafe maternity system by adding a sprinkle of central fetal monitoring and stirring.

  1. Thank you Kirsten- this is one decision I have been strongly opposing. Your blog tells it all-simply and plainly.
