The development and evaluation of a picture tongue assessment tool for tongue-tie in breastfed babies (TABBY).

Background: The presence of a tongue-tie (ankyloglossia) in an infant may lead to breastfeeding difficulties, but debate continues about which babies should be treated with frenotomy. The Bristol Tongue Assessment Tool (BTAT), a clear and simple evaluation of the severity of tongue-tie, is being used worldwide and translated into different languages. We aimed to produce a simple picture version of the BTAT to aid and enhance consistent assessment of infants with tongue-tie. Methods: The Tongue-tie and Breastfed Babies (TABBY) assessment tool was developed from the BTAT by a graphic designer, with iterative discussion with four practicing NHS midwives. The TABBY tool consists of 12 images demonstrating appearance of the infant tongue, its attachment to the gum and the limits of tongue mobility. The TABBY tool is scored from 0 to a maximum of 8.Two initial audits of the TABBY were undertaken at a large maternity unit in a secondary care NHS Trust, in Bristol UK from 2017 to 2019. TABBY was evaluated by five midwives on 262 babies with tongue-ties and experiencing breastfeeding difficulties who were referred for assessment to a tongue-tie assessment clinic using both BTAT and TABBY. Each pair of scores was recorded by one midwife at a time. A further training audit with 37 babies involved different assessors using BTAT and TABBY on each baby. Results: All midwives found the TABBY easy to use, and both audits showed 97.7% agreement between the scores. We suggest that a score of 8 indicates normal tongue function; 6 or 7 is considered as borderline and 5 or below suggests an impairment of tongue function. Selection of infants for frenotomy required an additional breastfeeding assessment, but all infants with a score of 4 or less in the audits had a frenotomy, following parental consent. Conclusions: The TABBY Assessment Tool is a simple addition to the assessment of tongue-tie in infants and can provide an objective score of tongue-tie severity. Together with a structured breastfeeding assessment it can inform selection of infants for frenotomy. It can be used by clinical staff following a short training and will facilitate translation into other languages.

The development of a tongue assessment tool to assist with tongue-tie identification.

AIM: To produce a simple tool with good transferability to provide a consistent assessment of tongue appearance and function in infants with tongue-tie. METHODS: The Bristol Tongue Assessment Tool (BTAT) was developed based on clinical practice and with reference to the Hazelbaker Assessment Tool for Lingual Frenulum Function (ATLFF). This paper documents 224 tongue assessments using the BTAT. There were 126 tongue assessments recorded using the BTAT and ATLFF tools to facilitate comparisons between them. Paired BTAT assessments were obtained from eight midwives who were using the new assessment tool. RESULTS: There was acceptable internal reliability for the four-item BTAT (Cronbach's α=0.708) and the eight midwives who used it showed good correlation in the consistency of its use (ICC=0.760). The BTAT showed a strong and significant correlation (0.89) with the ATLFF, indicating that the simpler BTAT could be used in place of the more detailed assessment tool to score the extent of a tongue-tie. Midwives found it quick and easy to use and felt that it would be easy to teach to others. CONCLUSIONS: The BTAT provides an objective, clear and simple measure of the severity of a tongue-tie, to inform selection of infants for frenotomy and to monitor the effect of the procedure.

The development of a new breast feeding assessment tool and the relationship with breast feeding self-efficacy.

OBJECTIVE: to develop a breast feeding assessment tool to facilitate improved targeting of optimum positioning and attachment advice and to describe the changes seen following the release of a tongue-tie. DESIGN: development and validation of the Bristol Breastfeeding Assessment Tool (BBAT) and correlation with breast feeding self-efficacy. SETTING: maternity hospital in South West England. PARTICIPANTS: 218 breast feeds (160 mother-infant dyads); seven midwife assessors. FINDINGS: the tool has more explanation than other tools to remind those supporting breast-feeding women about the components of an efficient breast feed. There was good internal reliability for the final 4-item BBAT (Cronbach's alpha=0.668) and the midwives who used it showed a high correlation in the consistency of its use (ICC=0.782). Midwives were able to score a breast feed consistently using the BBAT and felt that it helped them with advice to mothers about improving positioning and attachment to make breast feeding less painful, particularly with a tongue-tied infant. The tool showed strong correlation with breast feeding self-efficacy, indicating that more efficient breast feeding technique is associated with increased confidence in breast feeding an infant. CONCLUSIONS: the BBAT is a concise breast feeding assessment tool facilitating accurate, rapid breast feeding appraisal, and targeting breast feeding advice to mothers acquiring early breast feeding skills or for those experiencing problems with an older infant. Accurate assessment is essential to ensure enhanced breast feeding efficiency and increased maternal self-confidence. IMPLICATIONS FOR PRACTICE: the BBAT could be used both clinically and in research to target advice to improve breast feeding efficacy. Further research is needed to establish its wider usefulness.

Randomised controlled trial of early frenotomy in breastfed infants with mild-moderate tongue-tie.

TRIAL DESIGN: A randomised, parallel group, pragmatic trial. SETTING: A large UK maternity hospital. PARTICIPANTS: Term infants <2 weeks old with a mild or moderate degree of tongue-tie, and their mothers who were having difficulties breastfeeding. OBJECTIVES: To determine if immediate frenotomy was better than standard breastfeeding support. INTERVENTIONS: Participants were randomised to an early frenotomy intervention group or a 'standard care' comparison group. OUTCOMES: Primary outcome was breastfeeding at 5 days, with secondary outcomes of breastfeeding self-efficacy and pain on feeding. Final assessment was at 8 weeks; 20 also had qualitative interviews. Researchers assessing outcomes, but not participants, were blinded to group assignment. RESULTS: 107 infants were randomised, 55 to the intervention group and 52 to the comparison group. Five-day outcome measures were available for 53 (96%) of the intervention group and 52 (100%) of the comparison group, and intention-to-treat analysis showed no difference in the primary outcome-Latch, Audible swallowing, nipple Type, Comfort, Hold score. Frenotomy did improve the tongue-tie and increased maternal breastfeeding self-efficacy. At 5 days, there was a 15.5% increase in bottle feeding in the comparison group compared with a 7.5% increase in the intervention group. After the 5-day clinic, 44 of the comparison group had requested a frenotomy; by 8 weeks only 6 (12%) were breastfeeding without a frenotomy. At 8 weeks, there were no differences between groups in the breastfeeding measures or in the infant weight. No adverse events were observed. CONCLUSIONS: Early frenotomy did not result in an objective improvement in breastfeeding but was associated with improved self-efficacy. The majority in the comparison arm opted for the intervention after 5 days.
