Early neurological and motor function in infants born moderate to late preterm or small for gestational age at term: a prospective cohort study

BACKGROUND

There are inconsistent findings regarding neurological and motor development in infants born moderate to late preterm and infants born small for gestational age at term. The primary aim of this study was to compare neurological and motor function between preterm, term SGA and term AGA infants aged three to seven months corrected age using several common assessment tools. The secondary aim was to investigate their motor function at two years.

METHODS

In this prospective cohort study, we included 43 infants born moderate to late preterm with gestational age 32-36 + 6 weeks, 39 infants born small for gestational age (SGA) at term with a birthweight ≤ 10th centile for gestational age, and 170 infants born at term with appropriate weight for gestational age (AGA). Neurological and motor function were assessed once in infancy between three to seven months corrected age by using four standardised assessment tools: Hammersmith Infant Neurological Examination (HINE), Test of Infant Motor Performance, General Movements Assessment and Alberta Infant Motor Scale. The Ages and Stages Questionnaire (ASQ-2) was used at two years.

RESULTS

At three to seven months corrected age, mean age-corrected HINE scores were 61.8 (95% confidence interval (CI): 60.5 to 63.1) in the preterm group compared with 63.3 (95% CI: 62.6 to 63.9) in the term AGA group. Preterm infants had 5.8 (95% CI: 2.4 to 15.4) higher odds for HINE scores < 10th percentile. The other test scores did not differ between the groups. At two years, the preterm group had 17 (95% CI: 1.9 to 160) higher odds for gross motor scores below cut-off on ASQ-2 compared with the term AGA group.

CONCLUSIONS

The present study found subtle differences in neurological function between preterm and term AGA infants in infancy. At two years, preterm children had poorer gross motor function. The findings indicate that moderate prematurity in otherwise healthy infants pose a risk for neurological deficits not only during the first year, but also at two years of age when compared with term AGA children.

Evaluation of content validity and feasibility of the World Falls Guidelines' three key questions to identify falls among older adult users of home care services in Norway

BACKGROUND

Falls among older adults (65 + years) is an important issue in municipal home care. Screening using the World Falls Guidelines' three key questions (3KQ) is recommended to identify older adults at increased fall risk, but the 3KQ has not been formally tested by healthcare practitioners (HCPs) working in Norwegian municipal home care. The aim of this study was to evaluate the content validity and the feasibility of the 3KQ among HCPs in home care services.

METHODS

Participants were 10 multidisciplinary HCPs working in home care and in low-threshold services of Oslo, Norway. We evaluated the content validity of the 3KQ through individual think-aloud interviews. Next, feasibility was evaluated as follows: We trained HCPs in how to use the 3KQ. HCPs then screened older adults using the 3KQ during a six-week test period, and took pocket-notes of older adults' answers. We conducted two focus groups to explore HCPs' experiences with using the 3KQ. We analysed interview data using reflexive thematic analysis.

RESULTS

Content validity evaluation revealed that HCPs found the 3KQ easy to understand, and potentially timesaving. They experienced the tool as applicable among home care users, and it was particularly useful among new users. Still, HCPs emphasised the necessity of their training on how to best ask the questions and determine appropriate actions based on users' responses. We identified three main themes from the feasibility evaluation: (1) Promoting awareness and action: using the 3KQ helps put falls on the agenda in municipal home care, (2) Obtaining reliable answers: integrating the 3KQ into daily practice is important, and (3) Unlocking insights: the 3KQ as a gateway to supplementary information from users. Most older adults had increased fall risk according to the 3KQ.

CONCLUSIONS

The 3KQ appears feasible for Norwegian municipal home care and may be of value for HCPs who screen new users and users of low-threshold services. Integrated use of the 3KQ may enhance awareness, promote reliable answers, and provide supplementary information useful for decision-making. The study findings may benefit HCPs and managers in home care services, and other stakeholders in implementing fall prevention guidelines in primary care.
