Assessing genomics confidence and learning needs in Australian nurses and midwives: an educational program evaluation.

Introduction: The mainstreaming of genomics across healthcare specialties necessitates that all nurses and midwives have a high literacy in genomics. Methods: We aimed to design, develop, implement and evaluate a genomics education workshop for nurses and midwives using action research principles. Results: Registered nurses and midwives completed an online survey regarding genomics confidence and learning needs (n = 274). The results of this survey were used to develop the genomics education workshop. The workshop was run three times (n = 105) with evaluation data being collected both before and after each workshop. Significant improvements in confidence across all learning domains was found following the workshops (p < 0.001). A desire for more education across all learning domains except for genetics knowledge was also identified (p < 0.001). Discussion: Genomics education workshops were found to increase the confidence of nurses and midwives across a range of specialties. Nurses and midwives also expressed a desire for further education in genomics.

The congenital hearing phenotype in GJB2 in Queensland, Australia: V37I and mild hearing loss predominates.

GJB2 was originally identified in severe, non-syndromic sensorineural hearing loss (SNHL), but was subsequently associated with mild and moderate SNHL. Given the increasing utilisation of genetic testing pre-conceptually, prenatally, and neonatally, it is crucial to understand genotype-phenotype correlations. This study evaluated the nature and frequency of GJB2 variants in an Australian paediatric population with varying degrees of SNHL ascertained through newborn hearing screening. Audiograms from individuals with GJB2 variants and/or a GJB6 deletion (GJB6-D13S11830) were retrospectively reviewed (n = 127). Two-thirds were biallelic (homozygous/compound heterozygous) for pathogenic/likely pathogenic variants of GJB2 and/or GJB6 (n = 80). The most frequent variant was c.109 G > A, followed by c.35delG and c.101 T > C. Compared to biallelic carriage of other GJB2 variants, c.109 G > A positive individuals (homozygous/compound heterozygous) were more likely to have mild HL at their initial and latest audiograms (p = 0.0004). Biallelic carriage of c.35delG was associated with moderately-severe or greater SNHL at both initial and latest audiograms (p = 0.007). The c.101 T > C variant presented with milder SNHL and U-shaped audiograms (p = 0.02). In this agnostically identified cohort, mild SNHL predominated in GJB2/GJB6 carriers in contrast to previous studies targeting individuals with significant loss. Consequently, c.109 G > A, associated with milder phenotypes, was the most frequent. This study provides valuable data to support prognostic confidence in genetic counselling.
