Health-related quality of life and anxiety associated with childhood intermittent exotropia before and after surgical correction.

ABSTRACT:

Background

Intermittent exotropia (IXT) is the most common form of exotropia in children. In addition to cosmetic effects and loss of stereoscopic function, IXT may negatively impact the psychological well-being of children and their parents. The purpose of this study was to assess the patient-reported outcomes of Chinese children with IXT before and after strabismus surgery.

Methods

The records of children with IXT who underwent strabismus surgery at the Zhongshan Ophthalmic Center of Sun Yat-sen University, China over the period from January 1, 2016 to December 31, 2018 were prospectively recruited. All children underwent ophthalmic and orthoptic examinations, including the prism and alternate cover test, fusion function by synoptophore, stereoacuity and Newcastle control score. Two patient-reported outcome measures were used: the intermittent Exotropia Questionnaire (IXTQ) to measure disease-specific health-related quality of life (HRQOL) and the Hospital Anxiety and Depression Scale (HADS) to measure anxiety and depression. Patient-reported outcome measurements were made before and after surgery with responses from children and their parents.

Results

A total of 389 children were eligible for inclusion (47.8% male, 52.2% female, mean + SD age = 8.17 ± 2.81). Preoperative IXTQ scores in both children (48.21 ± 26.2) and their parents (44.6 ± 25.68) were significantly correlated with near stereoacuity (P = 0.029 and P = 0.015, respectively). The angle of deviation at near vision showed a negative linear relationship with visual function (P = 0.026) and psychological (P = 0.019) scores as well as opinions regarding surgery (P = 0.024). HADS scores (anxiety scale score: 11 ± 2.92, depression scale score: 10.44 ± 2.9) were also related to near stereoacuity (P < 0.05). After surgery, both children's (74.83 ± 16.59) and parents' (68.57 ± 17.06) IXTQ scores significantly improved (p<0.01). Children's IXTQ scores were related to the angle of deviation at distance, and their psychological and visual function scores showed a negative relationship with the angle of deviation at near vision (P < 0.05).

Conclusion

Children and parents' HRQOL and HADS were associated with near stereoacuity. Parents usually attend more readily to the angle of deviation at near in their IXT children. HRQOL improved significantly after surgery and can be used as one of the indices for preoperative evaluation but is not recommended as a criterion for surgical intervention.

Project description:PurposeThe development and initial validation of patient-derived, health-related quality-of-life (HRQOL) questionnaires for intermittent exotropia (IXT).DesignCross-sectional study.ParticipantsIn a development phase, 27 children (age, 2-17 years) with IXT and 1 of their parents. In an initial validation phase, 33 children with IXT and 49 control children (age, 5-17 years), along with 1 parent for each child. Children in the control group had no strabismus or amblyopia.MethodsIndividual patient interviews generated 35 items for child and proxy (parental assessment of child's HRQOL) questionnaires and 46 items for a parent questionnaire. To reduce to a feasible number of items, questionnaires were administered to 5- to 17-year-old children with IXT (n = 15) and parents of 2- to 17-year-old children with IXT (n = 27). Responses were analyzed using standard item reduction methodology. Three final derived IXT questionnaires (IXTQ): child, proxy, and parent (12, 12, and 17 items, respectively) were administered to children with IXT and control children and to parents of IXT and control children. Likert-type scales ranging from never (100, best HRQOL) to almost always (0, worst HRQOL) were used.Main outcome measuresMedian scores for IXT and control groups, compared using Wilcoxon tests.ResultsMedian child scores were significantly lower (worse HRQOL) in the IXT group compared with the control group: 85 (quartiles, 73-92) versus 92 (quartiles, 79-96; P = 0.04). Median proxy IXTQ scores were significantly lower for IXT children than controls: 83 (quartiles, 75-94) versus 98 (quartiles, 92-100; P<0.0001). Median parent IXTQ scores also were significantly lower in the IXT group compared with the control group: 68 (quartiles, 56-79) versus 93 (quartiles, 87-99; P<0.0001).ConclusionsA new 3-part patient-derived HRQOL questionnaire for children with IXT and their parents has been developed and validated, comprising child, proxy, and parent questionnaires. These questionnaires detect reduced HRQOL in children with IXT as reported by the children themselves and perceived by their parents (proxy report). Childhood IXT also seems to affect parent HRQOL. The IXTQ HRQOL questionnaires may prove useful in the clinical assessment of IXT and for clinical trials.Financial disclosure(s)The author(s) have no proprietary or commercial interest in any materials discussed in this article.

Project description:BackgroundExamining the quality of life (QOL) of patients before ICU admission will allow outcome variables to be compared and analyzed in relation to it. The objective of this study was to analyze QOL of patients before admission to a surgical ICU and to study its relationship to outcome and to the baseline characteristics of the patients.MethodsAll adult patients consecutively admitted to the surgical ICU between November 2004 and April 2005, who underwent non-cardiac surgery, were enrolled in this observational and prospective study. The following patient characteristics were recorded: age, gender, body mass index, ASA physical status, type and magnitude of surgical procedure, length of stay (LOS), in ICU and in hospital, mortality, Simplified Acute Physiology Score II (SAPS), history of co-morbidities and quality of life survey score (QOLSS). The relationships between QOLSS and ICU variables and outcome were evaluated. The relationship between the total QOLSS and each variable or outcome was assessed by multiple linear regression.ResultsOne hundred eighty seven patients completed the study. The preadmission QOLSS of the patients studied was 4.43 +/- 4.90; 28% of patients had a normal quality of life (0 points), 38% had between 1 and 5 points (considered mild deterioration), 21% had between 6 and 10 points (moderate deterioration), 10% had between 11 and 15 points (considered major deterioration) and 3% had more than 15 points (severe limitation of quality of life). A worse preadmission QOLSS was associated with higher SAPS II scores, with older patients (age> 65 years) and with ASA physical status (ASA III/IV). Total QOLSS was significantly worse in elderly patients and in patients with co-morbidities and in patients more severely ill at ICU admission. Patients who died in the ICU and in hospital had worse QOLSS scores compared to those who survived. However, no statistical differences in QOLSS were found in relation to longer ICU stays (ICU LOS).ConclusionPreadmission QOL correlates with age and severity of illness. Patients with co-morbidities and those who died during ICU or hospital stay had worse QOLSS scores.

Project description:Engaging patients (parents/families) in treatment decisions is increasingly recognised as important and beneficial. Yet where the evidence base for treatment options is limited, as with intermittent distance exotropia (X(T)), this presents a challenge for families and clinicians. The purpose of this study was to explore how decisions are made in the management and treatment of X(T) and what can be done to support decision-making for clinicians, parents and children.This was a qualitative study using face to face interviews with consultant ophthalmologists and orthoptists, and parents of children with X(T). Interview data were analysed using the constant comparative method.The drivers for clinicians in treatment decision-making for X(T) were the proportion of time the strabismus is manifest and parents' views. For parents, decisions were influenced by: fear of bullying and, to a lesser degree, concerns around the impact of the strabismus on their child's vision. Uncertainty around the effectiveness of treatment options caused difficulties for some clinicians when communicating with parents. Parental understanding of the nature of X(T) and rationale for treatment often differed from that of the clinicians, and this affected their involvement in decision-making. Though there were good examples of shared decision-making and parent and child engagement some parents said the process felt rushed and they felt excluded. Parents reported that clinicians provided sufficient information in consultations but they had difficulties in retaining verbal information to convey to other family members.Overall parents were happy with the care their child received but there is scope for better parent and (where appropriate) child engagement in decision-making. There was an expressed need for written information about X(T) to reinforce what was given verbally in consultations and to share with other family members. Access could be via the hospital website, along with videos or blogs from parents and children who have undergone the various management options. A method of assisting clinicians to explain the treatment options, together with the uncertainties, in a clear and concise way could be of particular benefit to orthoptists who have the most regular contact with parents and children, and are more likely to suggest conservative treatments such as occlusion and minus lenses.
