Development of an Outcome Measure of Observable Signs of Health and Well-Being in Infants With Orofacial Clefts

Observations by Caregivers Using the Infant with Clefts Observation Outcomes Instrument (iCOO): A Comparison of Three Versus Seven-day Daily Diaries

OBJECTIVE

Our goal was to compare data collected from 3- and 7-day Infant with Clefts Observation Outcomes (iCOO) diaries.

DESIGN

Secondary data analysis of an observational longitudinal cohort study. Caregivers completed the daily iCOO for 7 days before cleft lip surgery (T0) and for 7 days after cleft lip repair (T1). We compared 3- and 7-day diaries collected at T0 and 3- and 7-day diaries collected at T1.

SETTING

United States.

PARTICIPANTS

Primary caregivers of infants with cleft lip with and without cleft palate (N  =  131) planning lip repair and enrolled in original iCOO study.

MAIN OUTCOMES MEASURE(S)

Mean differences and Pearson correlation coefficients.

RESULTS

Correlation coefficients were high for global impressions (>0.90) and scaled scores (0.80-0.98). Mean differences were small across iCOO domains at T0. T1 comparisons reflected the same pattern.

CONCLUSIONS

Three-day diary data is comparable to 7-day diaries for measuring caregiver observations using iCOO across T0 and T1.

Caregiver Observations of Infant Well-Being Before and After Cleft Lip Surgery

OBJECTIVE

To evaluate the sensitivity to change of daily ratings of the comfort (COMF) and behavioral/emotional health (BEH) domains of the Infants with Clefts Observation Outcomes Instrument (iCOO) at 3 time points, and to assess the association of post-surgical interventions on iCOO ratings.

DESIGN

The COMF and BEH domains were completed by caregivers before (T0), immediately after (T1), and 2-months after (T2) cleft lip (CL) surgery. Analyses included descriptive statistics, correlations, t-tests, and generalized estimating equations.

PARTICIPANTS

Caregivers (N  =  140) of infants with CL with/without cleft palate.

MAIN OUTCOME MEASURES

The COMF and BEH domain scores of the iCOO: Scale (SCALE), a summary of observable signs; and Global Impression (IMPR), a single item measuring caregivers' overall impression.

RESULTS

Daily COMF and BEH SCALE and IMPR scores changed significantly during T1 (P's < 0.001) but not T0 or T2. Day 1 and 7 T0 scores were significantly higher than Day 1 and 7 T1 scores (P's <0.001 to <0.012) but similar at T2 (P's > 0.05). After CL surgery, the combined use of immobilizers and nasal stents and the use of multiple feeding methods with treatment for gastroesophageal reflux were associated with lower daily scores in COMF and BEH SCALE and IMPR (P's: 0.040 to <0.001).

CONCLUSIONS

COMF and BEH iCOO scores were sensitive to daily changes in infant well-being following CL surgery. Future studies should further investigate impact of post-surgical treatments on infant well-being.

Developmental Risk for Infants with Cleft Lip with or Without Cleft Palate Based on Caregiver-Proxy Reports

OBJECTIVES

(1) Assess caregiver-reported development in infants born with cleft lip ± alveolus (CL ± A) and cleft lip and palate (CLP); (2) determine factors associated with increased developmental risk; and (3) determine consistency of developmental risk before and after surgery for cleft lip.

DESIGN

Prospective, longitudinal assessment of development. Time (T) 1, prior to lip closure; T2, 2 months post lip closure.

SETTING

Three US craniofacial teams and online parent support groups.

PARTICIPANTS

123 total caregivers (96% mothers); 100 at T1, 92 at T2, and 69 at both T1 and T2.

MEASURE

Ages and Stages Questionnaire-3 (ASQ-3): Communication, Gross Motor, Fine Motor, Problem Solving, Personal Social Domains.

RESULTS

At T1 47%; at T2 42% passed all 5 Domains; 36% of infants pass all 5 Domains at both T1 and T2. Infants with CLP were at greatest risk on Communication [B = 1.449 (CI = .149-20.079), p = .038; Odds Ratio (OR) = 4.3 (CI = .923-19.650)] and Gross Motor Domains [B = 1.753 (CI = .316-20.605), p = .034; OR = 5.8 (CI = 1.162-28.671)]. Male infants were at greatest risk on Fine Motor [B = 1.542 (CI = .495-20.005), p = .009; OR = 4.7 (CI = 1.278-17.101)] and Problem Solving Domains [B = 1.200 (CI = .118-19.708), p = .044; OR = 3.3 (CI = .896-12.285)].

CONCLUSIONS

Based on caregiver report, infants with CL ± A and CLP meet referral criteria at a high rate. Infants with CLP and male infants were at greatest risk. Regular developmental screening is recommended.

Topical fluoride hesitancy among caregivers: Development of a content-valid topical fluoride hesitancy identification item pool

OBJECTIVES

To develop a content-valid set of items to characterize different types of topical fluoride hesitancy among caregivers. We will use this information to develop and test tailor-made interventions directed to caregivers with varied types and levels of topical fluoride hesitancy, to ultimately improve child oral health.

METHODS

Caregivers participated in three study activities, in the following order: (1) semi-structured concept elicitation interviews (n = 56), (2) cognitive interviews (n = 9), and (3) usability interviews (n = 3). Interviews were conducted via telephone and audio-recorded and transcribed for qualitative analysis. Twelve pediatric dental providers and researchers participated in item review. An assessment of reading level of items was made with goal of 6th grade reading level or less.

RESULTS

Based on elicitation interviews, we initially developed 271 items, which the investigative team evaluated for conceptual clarity, specificity to topical fluoride hesitancy, and sensitivity to potential interventions. After four rounds of review and cognitive interviews, we retained 33 items across five previously identified domains. Changes after cognitive interviews included item revision to improve comprehension and item re-ordering to avoid order effects. Changes after usability testing including clarification regarding referent child for families with multiple children. The reading level of the item pool is grade 3.2.

CONCLUSIONS

The resulting 33-item fluoride hesitancy item pool is content valid and will address an important need for identifying and addressing topical fluoride hesitancy in the context of dental research and clinical practice. Next steps include psychometric evaluation to assess scale and test-retest reliability and construct validity.

Exploration of Caregiver Interrater Agreement and Test-Retest Reliability on the Infant Cleft Observer Outcomes (iCOO)

Caregiver and observer-reported measures are frequently used as outcomes for research on infants and young children who are unable to report on their own health. Our team developed the Infant with Clefts Observation Outcomes Instrument (iCOO) for infants with cleft lip with or without cleft palate. This exploratory study compared test-retest and interrater reliabilities to inform whether differences in caregiver perspective might affect the iCOO.

This study is a secondary analysis comparing caregiver interrater agreement to test-retest reliability. Twenty-five pairs of caregivers completed the iCOO before surgery, 1 week later for test-retest reliability, 2 days after surgery, and 2 months after surgery. Reliability was assessed using intraclass correlations (ICCs) and t-tests were used to compare ratings between caregivers.

Infants had cleft lip (28%) or cleft lip and palate (72%). Primary caregivers were predominantly mothers (92%) and secondary caregivers were predominantly fathers (80%). Test-retest reliability met psychometric standards for most items on the iCOO (81%-86% of items). Caregiver agreement on the iCOO items was lower than test-retest reliability (33%-46% of items met psychometric standards). Caregivers did not systematically differ in whether they rated infants as healthier or less healthy than the other caregiver (5%-16% of items had statistically significant differences).

Caregivers used the measure consistently, but had different experiences and perceptions of their infant's health and functioning. Future studies are needed to explore mechanisms for the differences in test-retest and interrater reliability. Whenever possible, the same caregiver should provide ratings of the infant, including on the iCOO.

Infant with Clefts Observation Outcomes Instrument (iCOO): A New Outcome for Infants and Young Children with Orofacial Clefts

OBJECTIVE

We evaluated the measurement properties for item and domain scores of the Infant with Clefts Observation Outcomes Instrument (iCOO).

DESIGN

Cross-sectional (before lip surgery) and longitudinal study (preoperative baseline and 2 days and 2 months after lip surgery).

SETTING

Three academic craniofacial centers and national online advertisements.

PARTICIPANTS

Primary caregivers with an infant with cleft lip with or without cleft palate (CL  ±  P) scheduled to undergo primary lip repair. There were 133 primary caregivers at baseline, 115 at 2 days postsurgery, and 112 at 2 months postsurgery.

MAIN OUTCOME MEASURE(S)

Caregiver observation items (n = 61) and global impression of health and function items (n = 8) across eight health domains.

RESULTS

Mean age at surgery was 6.0 months (range 2.7-11.8 months). Five of eight iCOO domains have scale scores, with Cronbach's alphas ranging from 0.67 to 0.87. Except for the Facial Skin and Mouth domain, iCOO scales had acceptable intraclass correlation coefficients (ICCs) ranging from 0.76 to 0.84. The internal consistency of the Global Impression items across all domains was 0.90 and had acceptable ICCs (range 0.76-0.91). Sixteen out of 20 (nonscale) items had acceptable ICCs (range 0.66-0.96). As anticipated, iCOO scores 2 days postoperatively were generally lower than baseline and scores 2 months postsurgery were consistent with baseline or higher. The iCOO took approximately 10 min to complete.

CONCLUSIONS

The iCOO meets measurement standards and may be used for assessing the impact of cleft-related treatments in clinical research and care. More research is needed on its use in various treatment contexts.
