Prescription of antibiotics to children with acute otitis media in Danish general practice.

BACKGROUND: Acute otitis media (AOM) is a common and most often self-limiting infection in childhood, usually managed in general practice. Even though antibiotics are only recommended when certain diagnostic and clinical criteria are met a high antibiotic prescription rate is observed. The study's objective was to analyse associations between patient- and general practitioner (GP) characteristics and antibiotic prescribing for children with AOM in an effort to explain the high antibiotic prescribing rates. METHODS: All general practices in the Northern, Southern and Central regions of Denmark were invited to record symptoms, examinations, findings and antibiotic treatment for all children ≤7 years of age diagnosed with AOM during a four-week winter period in 2017/2018. Associations were analysed by means of multivariate logistic regressions. The study design was cross-sectional. RESULTS: GPs from 60 general practices diagnosed 278 children with AOM of whom 207 (74%) were prescribed antibiotics, most often penicillin V (60%). About half of the children had tympanometry performed. Antibiotic prescribing rates varied considerably between practices (0-100%). Antibiotic prescribing was associated with fever (odds ratio (OR) 3.69 95% confidence interval (CI) 1.93-7.05), purulent ear secretion (OR 2.35 95% CI 1.01-5.50) and poor general condition (OR 3.12 95% CI 1.31-7.46), and the practice's antibiotic prescribing rate to other patients with symptoms of an acute respiratory tract infection (OR 2.85 CI 95% 1.07-7.60) and specifically to other children with AOM (OR 4.15 CI 95% 1.82-9.47). CONCLUSION: GPs' antibiotic prescribing rates for children with AOM vary considerably even considering the of signs, symptoms, request for antibiotics, and use of tympanometry. Interventions to reduce overprescribing should be targeted high-prescribing practices.

Resources in vulnerable young adults: self-assessments during preventive consultation with their general practitioner in Denmark.

Inequality in health is increasing. People with many problems often lack energy to improve well-being and reduce their problems. This study analyses how psycho-socially challenged younger (20- to 44-year-old) patients described their own resources to reach lifestyle goals or alter life circumstances. Within the context of a randomized controlled trial, Danish participants had two structured preventive person-centred consultations with their general practitioner. Consultations focused on well-being, salutogenesis, resources, barriers and support of autonomy. Using the qualitative method: Systematic Text Condensation, we made thematic cross-analysis of patients' goal-specific resource statements described at the first consultation. Of the 209 patients, 191 (91%) chose one or two goals for a better life next year; nearly all (179) could recall and describe which resources they would use to reach their goal. We categorized resource statements into (i) personal constitution as 'willpower' and 'tenacity'; (ii) network, e.g. family; (iii) personal experience with identical or similar problems. Some patients needed to free up resources by handling psychological problems before being able to focus on lifestyle goals. The study demonstrates that patients with particular psycho-social problems could describe essential resources in a structured, salutogenic, preventive consultation with their general practitioner. Reflecting intrinsic and extrinsic motivation, these resources reflected dimensions of essential health theories like sense of coherence, self-efficacy and self-determination theory. Increased awareness of these resources seems essential for vulnerable patients by improving psychological well-being and optimism, thereby facilitating health-related changes. This may be an important step to reducing inequality in health.

Smartphone otoscopy by non-specialist health workers in rural Greenland: A cross-sectional study.

INTRODUCTION: Greenland has one of the highest prevalences of otitis media in the world. However, access to ear specialists throughout Greenland is limited and currently there are no national guidelines for treatment or prevention. Tele-otoscopy may be beneficial in optimizing diagnosis and treatment. The smartphone otoscopy device, Cupris®, has previously been validated when used by medical doctors on a population primarily consisting of adults. In this study we evaluated the usability of the Cupris® otoscope when used by local health care workers with different levels of training and education, examining children aged 1-6 years. METHODS: We conducted a cross-sectional study in three Greenlandic towns. Health care personnel were asked to perform video-otoscopy on children contacting the health clinic for any reason. The videos were sent for remote evaluation by three ear specialists who rated the videos on a five-point Likert scale and provided information on challenges with the videos. The dichotomous outcome "not useful/useful" was defined as 1-3 and 4-5 on the Likert scale, respectively. RESULTS: In total, 142 videos were recorded on 84 patients. Mean proportion of useful videos was 18.1%, with a modified Fleiss' Kappa interrater agreement coefficient of 0.67 95% CI [0.57-0.76] corresponding to substantial agreement among the three raters. CONCLUSIONS: In this study the usefulness of the Cupris® TYM otoscope did not prove to be sufficient with the presented instruction in the hands of local health care workers when examining Greenlandic children. Focus on training and education of local health personnel is crucial and warranted before advantageous implementation for non-specialist health care workers can be expected.

Preschool children in Danish out-of-hours primary care: a one-year descriptive study of face-to-face consultations.

BACKGROUND: The demand for out-of-hours (OOH) primary care has increased during the last decades, with a considerable amount of contacts for young children. This study aims to describe the reasons for encounter (RFE), the most common diagnoses, the provided care, and the parental satisfaction with the general practitioner (GP) led OOH service in a Danish population of children (0-5 years). METHODS: We conducted a one-year cross-sectional study based on data for 2363 randomly selected contacts concerning children from a survey on OOH primary care including 21,457 patients in Denmark. For each contact, the GPs completed an electronic pop-up questionnaire in the patient's medical record. Questionnaire items focussed on RFE, health problem severity, diagnosis, provided care, and satisfaction. The parents subsequently received a postal questionnaire. RESULTS: The most common RFE was non-specific complaints (40%), followed by respiratory tract symptoms (23%), skin symptoms (9%), and digestive organ symptoms (8%). The most common diagnosis group was respiratory tract diseases (41%), followed by general complaints (19%) and ear diseases (16%). Prescriptions were dispensed for 27% of contacts, and about ¾ were for antibiotics. A total of 12% contacts concerned acute otitis media; antibiotics were prescribed in 70%. A total of 38% of contacts concerned fever, and » got antibiotics. A total of 7.4% were referred for further evaluation. The parental satisfaction was generally high, but 7.0% were dissatisfied. Dissatisfaction was correlated with low prescription rate. CONCLUSION: Respiratory tract diseases were the most common diagnoses. The GPs at the OOH primary care service referred children to hospital in 7.4% of the face-to-face consultations, and the provided care was evaluated as non-satisfying by only 7.0% of the parents. Clinical implications of the findings mean room for less prescription of antibiotic to children with ear diseases and a need for research in factors related to dissatisfaction.

Validation of a health screening questionnaire for primary care using Rasch models.

BACKGROUND: Health inequality is on the rise due to various social and individual factors. While preventive health checks (PHC) aim to counteract health inequality, there is robust evidence against the use of PHC in general practice. It is unknown which factors can identify persons who will benefit from preventive interventions that are more beneficial than harmful. Hence, valid screening instruments are needed. METHODS: The aim of this study was to assess the psychometric properties of a screening questionnaire (SQ-33), which targets vulnerable persons in primary care practice who can benefit from preventive consultations. Survey data were acquired from 20 primary care clinical practices in the Northern Region of Jutland, Denmark. Respondents were 2056 persons between 20 and 44 years old who, for any reason, consulted their family doctor. The psychometric properties of the SQ-33 were assessed using Rasch item response modelling. Follow-up analysis was performed on a subsample of 364 persons one year subsequent to initial inclusion, in order to assess responsiveness and predictive validity using a general health anchor item. RESULTS: Twenty-three of the SQ-33 items in four subscales fit a Graphical loglinear Rasch model (GLLRM) at baseline and follow-up, thus confirming the scaling properties. The modified 23-item version (HSQ-23) revealed superior responsiveness and predictive validity compared with the SQ-33. CONCLUSIONS: The Health Screening Questionnaire (HSQ-23) was shown to possess adequate psychometric properties and responsiveness and can thus be used as an outcome measure in preventive intervention studies. Future study should address whether the HSQ-23 successfully identifies patients who will benefit from PHC consultations.

Comparison of the Reynell Developmental Language Scale II and the Galker test of word-recognition-in-noise in Danish day-care children.

OBJECTIVE: To search for predictive factors for language development measured by two receptive language tests for children, the Galker test (a word-recognition-in-noise test) testing hearing and vocabulary, and the Danish version of Reynell Developmental Language Scale (2nd revision, RDLS II) test, a language comprehension test. The study analysed if information about background variables and parents and pre-school teachers was predictive for test scores; if earlier middle ear disease, actual hearing loss and tympanometry was important for language development; and if the two receptive tests differed in terms of the degree to which variables were able to predict test scores at the age of three to five years. METHODS: All children aged three and five years attending 20 day-care centres for children without cognitive development issues from the Municipality of Hillerød, Denmark, were invited to participate. We used questionnaires to the parents and day-care teachers and examined the children using tympanometry, hearing test and the two receptive language tests. We performed unadjusted and adjusted analyses of raw and grouped scores and background variables, as well as stepwise regression analysis with group scores as outcome. RESULTS: The results of the two tests were surprisingly similar in relation to background variables. The same variables were predictive for scores in the two receptive language tests. The predictive variables were: age group (22-31%), having no sibling (2-3%), being a boy (1%), information from the parents about the child's vocabulary (3%), phonology (0-2%). information from the pre-school teachers on the child's vocabulary (4-6%), and hearing beyond 25 dB in best ear (mean of four frequencies) (1%). CONCLUSION: We found that nearly the same variables were predictive for the test score and the grouped score in pre-school children in the RDLS II and the Galker test. Information from the pre-school teachers was more predictive of the test score than information from the parents. In the adjusted analysis, beside age group, information about the child's vocabulary was the most predictive information explaining 4-6% of the variation.

Risk of childhood otitis media with focus on potentially modifiable factors: A Danish follow-up cohort study.

INTRODUCTION: Otitis media is the primary cause of antibiotic prescription in children. Two-thirds of all children experience at least one episode of otitis media before the age of 7 years. The aim of this study was to characterise the attributable effect of several modifiable risk exposures on the risk of >3 episodes of otitis media at age 18 months and 7 years within a large prospective national birth cohort. METHODS: The study used the Danish National Birth Cohort comprising information about otitis media and risk exposures from more than 50,000 mother-child pairs from the period 1996-2002. Logistic regression models were used to estimate odds ratios for the risk factors and to calculate the population attributable fraction. RESULTS: Short time with breastfeeding, early introduction to daycare, cesarean section, and low compliance to the national vaccination program were all associated with an increased risk of >3 episodes of otitis media at 18 months of age and at 7 years of age. The fraction of children with otitis media attributed from breastfeeding lasting for less than 6 months was 10%. Introduction to daycare before the age of 12 months attributed with 20% of the cases of >3 episodes of otitis media. CONCLUSIONS: Short duration of breastfeeding, early introduction into daycare, cesarean section, and low compliance with the national vaccination program increased the risk of experiencing >3 episodes of otitis media at 18 months, and at 7 years of age. These are factors that all can be modulated.

Early childhood otitis media and later school performance - A prospective cohort study of associations.

INTRODUCTION: Otitis media (OM) is a common disease in childhood and hearing loss (HL) is the most common complication. Prolonged HL may lead to language delay and cognitive difficulties. However, the consequences of HL due to OM are not fully understood. The aim of this study was to determine the possible association between number of OM episodes in childhood and self-rated school performance controlling for potential confounders. METHODS: Prospectively gathered systematic interview data on OM episodes in early childhood and school performance at 11 years of age were obtained from The Danish National Birth Cohort, involving >100,000 individual pregnancies and their offspring. We defined four exposure groups (0, 1-3, 4-6 and ≥7 OM episodes) and assessed general school performance, mathematics and literacy. Possible confounders were recognized à priori and associations were determined using proportional odds regression. RESULTS: Out of 94,745 successful pregnancies, 35,946 children without malformations and their parents completed a questionnaire at age 11 years. No associations were observed between number of OM episodes and school performance, even in children with ≥7 OM episodes. CONCLUSION: This national birth-cohort study did not support the hypothesis that the number of OM episodes in childhood is associated with reduced self-reported school performance in children at 11 years of age.

Risk Factors of Early Otitis Media in the Danish National Birth Cohort.

OBJECTIVE: To assess risk factors of otitis media (OM) in six-months-old children. METHOD: The sample consisted of 69,105 mothers and their children from the Danish National Birth Cohort. The women were interviewed twice during pregnancy and again 6 months after birth. The outcome "one or more" maternal reported episodes of OM at age six months. In total 37 factors were assessed, covering prenatal, maternal, perinatal and postnatal factors. RESULTS: At age six months 5.3% (95% CI 5.1-5.5) of the children had experienced one or more episodes of OM. From the regression analysis, 11 variables were associated with a risk of OM. When a Bonferroni correction was introduced, gender, prematurity, parity, maternal age, maternal self-estimated health, taking penicillin during pregnancy, and terminating breastfeeding before age six months, was associated with a risk of early OM. The adjusted ORs of OM for boys versus girls was 1.30 (95% CI 1.18-1.44). The OR having one sibling versus no siblings was 3.0 (95% CI 2.64-3.41). If the woman had been taking penicillin during pregnancy, the OR was 1.35 (95% CI 1.15-1.58). Children born before 38th gestational week had an increased OR for early OM of 1.49 (95% CI 1.21-1.82). Children of young women had an increased OR of early OM compared to children of older women. Additionally, children of women who rated their own health low compared to those rating their health as high, had an increased OR of 1.38 (95% CI 1.10-1.74). Finally, children being breastfeed less than 6 months, had an increased OR of 1.42 (95% CI 1.28-1.58) compared to children being breastfeed beyond 6 months. CONCLUSION: These findings indicate that prenatal factors are of less importance regarding early OM before the age of six months. Postnatal risk factors seem to pose the main risk of early OM.

Predictors of weight loss in young adults who are over-weight or obese and have psychosocial problems: a post hoc analysis.

BACKGROUND: The aim of this study is in a general practice trial setting to identify predictive factors for weight loss after 1 year among young adults who are over-weight or obese and who have several psychosocial problems. METHODS: Twenty-eight general practitioners recruited 495 patients aged 20-45 years with psychosocial problems for a randomized general preventive study to increase self-efficacy to achieve a self-prioritised goal for a better life by discussions of resources and barriers for reaching the goal. The present study is a post hoc analysis of possible predictors of weight loss among all 218 patients who have over-weight or obesity. A 23-pages questionnaire was completed before and 1 year after randomization. 111 patients had a one-hour preventive health consultation with their general practitioners focused on life coaching and a follow-up consultation within 3 months, and 107 patients had no preventive consultation. RESULTS: Twenty-two patients stated during the preventive consultation that weight loss was a prioritised goal. They had a mean weight loss of 4.7 kgs compared with 1.6 kgs in the group without this goal and 1.6 kgs in the group without preventive consultation. In a logistic regression model, predictors of weight loss or no weight loss were a) pre-interventional consideration of weight loss within 30 days, b) having weight loss as a prioritised goal for improved quality of life, c) being female, d) being in the oldest half of participants, and e) having many psychosocial problems. In a linear regression model, the predictors together explained about 11% of the weight loss. Important predictors were: obesity (explained 4%), pre-interventional consideration of weight loss within 30 days (3%), and having a preventive health consultation with weight loss as a prioritised goal (2%). CONCLUSIONS: Pre-interventional consideration of weight loss within 30 days and having weight loss as a prioritised goal during the health consultation were two important predictors for weight loss. By structured interventions focussing on the patients' priorities, self-chosen goals, their resources and barriers for reaching the goals, changes may be obtained; especially in participants with many problems who often do not accept participation in procedures on risks.

The Galker test of speech reception in noise; associations with background variables, middle ear status, hearing, and language in Danish preschool children.

PURPOSE: We tested "the Galker test", a speech reception in noise test developed for primary care for Danish preschool children, to explore if the children's ability to hear and understand speech was associated with gender, age, middle ear status, and the level of background noise. METHODS: The Galker test is a 35-item audio-visual, computerized word discrimination test in background noise. Included were 370 normally developed children attending day care center. The children were examined with the Galker test, tympanometry, audiometry, and the Reynell test of verbal comprehension. Parents and daycare teachers completed questionnaires on the children's ability to hear and understand speech. As most of the variables were not assessed using interval scales, non-parametric statistics (Goodman-Kruskal's gamma) were used for analyzing associations with the Galker test score. For comparisons, analysis of variance (ANOVA) was used. Interrelations were adjusted for using a non-parametric graphic model. RESULTS: In unadjusted analyses, the Galker test was associated with gender, age group, language development (Reynell revised scale), audiometry, and tympanometry. The Galker score was also associated with the parents' and day care teachers' reports on the children's vocabulary, sentence construction, and pronunciation. Type B tympanograms were associated with a mean hearing 5-6dB below that of than type A, C1, or C2. In the graphic analysis, Galker scores were closely and significantly related to Reynell test scores (Gamma (G)=0.35), the children's age group (G=0.33), and the day care teachers' assessment of the children's vocabulary (G=0.26). CONCLUSIONS: The Galker test of speech reception in noise appears promising as an easy and quick tool for evaluating preschool children's understanding of spoken words in noise, and it correlated well with the day care teachers' reports and less with the parents' reports.

A speech reception in noise test for preschool children (the Galker-test): Validity, reliability and acceptance.

PURPOSE: This study evaluates initial validity and reliability of the "Galker test of speech reception in noise" developed for Danish preschool children suspected to have problems with hearing or understanding speech against strict psychometric standards and assesses acceptance by the children. METHODS: The Galker test is an audio-visual, computerised, word discrimination test in background noise, originally comprised of 50 word pairs. Three hundred and eighty eight children attending ordinary day care centres and aged 3-5 years were included. With multiple regression and the Rasch item response model it was examined whether the total score of the Galker test validly reflected item responses across subgroups defined by sex, age, bilingualism, tympanometry, audiometry and verbal comprehension. RESULTS: A total of 370 children (95%) accepted testing and 339 (87%) completed all 50 items. The analysis showed that 35 items fitted the Rasch model. Reliability was 0.75 before and after exclusion of the 15 non-fitting items. In the stepwise linear regression model age group of children could explain 20% of the variation in Galker-35-score, sex 1%, second language at home 4%, tympanometry in best ear 2%, and parental education another 2%. Other variable did not reach significance. CONCLUSION: The Galker-35 was well accepted by children down to the age of 3 years and results indicate that the scale represents construct valid and reliable measurement.

Incidence of otitis media in a contemporary Danish National Birth Cohort.

OBJECTIVES: In recent years welfare in Denmark has increased which might be expected to reduce otitis media (OM) incidence. We examined the age-specific incidence of OM in a nation-wide cohort of children aged 0-7 years born in 1996-2003 (Danish National Birth Cohort, DNBC). Only selection was ability to understand and speak Danish. METHODS: Information of OM and ventilation tubes (VT) was collected through three maternal interviews at 6-month, 18-month and 7-years of age and based on this age-specific and cumulative incidence of OM was calculated. As different numbers of the total population answered the different interviews, the calculations are done with different denominators. The information in DNBC was validated against two population based registries containing information of VT insertions. RESULTS: Cumulative incidence of OM at 7 years was 60.6% (31,982/52,755). For children with OM, 16.2% (7143/44194) had their first OM episodes between 0-6 months of age, 44.3% (19579/44194) between 7-18 months, and 39.5% (17472/44194) between 19 months and 7 years. Four or more OM episodes before 7 years were reported by 39.5% (12620/31982) and by 64.0% (2482/3881) of those who had their OM debut between 0-6 months; by 48.2% (4998/10378) with debut between 7-18 months; and by 28.7% (4996/17344) with debut between 19 months and 7 years. These figures are essentially unchanged from earlier figures from Denmark. VT insertion at least once was reported by 26,1% in the 7-year interview. Assuming recordings in the Danish National Patient Registry to be gold standard, maternal self-reportings in DNBC of insertion of VT showed high sensitivity (96.4%), specificity (98.2%), and positive (94.8%) and negative predictive values (98.8%). CONCLUSION: OM affects nearly 2/3 of preschool children in Denmark despite reduction in known OM risk factors.

The impact of non-responders on health and lifestyle outcomes in an intervention study.

BACKGROUND: A randomized intervention study, "Preventive consultations for 20- to 40-year-old young adults", investigated whether preventive consultations with a general practitioner could help young adults with multiple psychosocial and lifestyle problems to change health behavior. To optimize the response rate of questionnaires at 1 year post-intervention, the non-responders were reminded by telephone. The aim of this study was to examine potential selection bias induced by non-response by comparing responder and non-responder populations at baseline, and to examine the impact on outcomes by comparing initial respondents to respondents after telephone reminding. METHOD: Non-responders were compared with primary responders using logistic regression models that included socio-demographic factors, health-related factors, and variables related to the intervention study. In order to describe the impact of including responders after telephone reminding on the intervention's effect on different health, resource, and lifestyle outcomes, we compared results in models including and excluding responders after telephone reminding. RESULTS: Telephone contact raised the response by 10% from 316 (64%) to 364 (74%) among young adults with multiple problems. Being male was the only factor that significantly predicted non-response in the model after adjustment for other variables. The responders after telephone reminding tended to improve health and lifestyle more than the primary responders, but not significantly so. Although the additional responses did not change the estimates of the 1-year effect on health and lifestyle changes, it contributed to increased precision of the results. CONCLUSION: Even though the population of primary non-responders had to some degree a different composition than the primary responders, inclusion of responders after telephone reminding did not significantly change the estimates for effect at the 1-year follow-up; however, the additional responses increased the precision of the estimates.

The importance of gender of patients and general practitioners in relation to treatment practices for overweight.

BACKGROUND: Several studies suggest that men and women are treated differently for similar disease including diabetes and cardiovascular disease. Differences in attitudes and treatment practices towards men and women with obesity are not well recognized. OBJECTIVE: To investigate the attitudes and treatment practices among Danish general practitioners (GPs), in relation to treatment of overweight, while taking gender of both the patients and practitioners into account. DESIGN: Questionnaire inventory covertly examining attitudes and practices among Danish general practitioners towards treatment of overweight. All 3.637 general practitioners from the Danish Medical Association register were invited to participate in the survey. In total 1.136 participated. RESULTS: The GPs found weight loss to be more important for overweight male than overweight female patients. They also treated complications to overweight more rigorously among male than female patients, and recommended lipid lowering medicine more often to male than female overweight patients. In addition, the younger female GPs and older male GPs more often said that they would treat an overweight patient with lipid lowering medicine. CONCLUSION: Among general practitioners in Denmark, treatment for weight loss is more often practiced for overweight male than overweight female patients presenting with same symptoms. In addition, hyperlipidemia among overweight males is also more often treated with lipid lowering medicine than hyperlipidemia among overweight females.

Large cohort study finds a statistically significant association between excessive crying in early infancy and subsequent ear symptoms.

AIM: The diagnosis of infantile colic is based on excessive crying. However, several causal factors can account for this disconcerting, nonspecific symptom. The main aim of this study was to investigate a possible association between excessive crying during the first 6 months of life and subsequent ear problems. METHODS: Data from a cohort study of 26 983 Danish children were used. Mothers participated in four telephone interviews and one questionnaire and provided information on crying in the first 6 months of life and ear symptoms at the ages of 6 months, 18 months and 7 years. RESULTS: There was a statistically significant association between excessive crying in infancy and subsequent ear symptoms. A gradual increase in subsequent ear problems was seen with increasing crying time at all the data collection times. CONCLUSIONS: The results of this study suggest a possible link between excessive crying and ear infections. Whether such a link is causal or due to common underlying factors is still unknown. We recommend thorough ear examinations in children with symptoms compatible with infantile colic.

Quality of life in children with otitis media--a cohort study.

BACKGROUND: Studies about health-related quality of life (HRQOL) in children with otitis media have primarily focused on short-term effects of the disease, and how treatment with insertion of ventilation tubes (VTs) affects the HRQOL. More knowledge is needed about how long-term HRQOL is associated with different factors like insertion of VT and use of antibiotics. OBJECTIVE: We aimed to analyse HRQOL in children with otitis media 1 year after inclusion and to what extent insertion of VT, use of antibiotics, diagnoses, symptoms in the children, day-care attention, parental absence from work and parental smoking were associated with the long-term HRQOL in children with otitis media. METHODS: A cohort study including 397 children was carried out. The children were followed for 13 months, and symptoms, HRQOL and so on were identified by means of questionnaires. RESULTS: HRQOL in children with otitis media was significantly improved after 13 months. The improvement of HRQOL was significantly lower for children with sleep problems compared with children without sleep problems. The improvement in HRQOL was significantly lower in children whose parents had been absent from work during the preceding 3 months due to the child' s otitis media compared with children with parents not being absent from their work. There were no statistically significant differences in the improvement of HRQOL in children who had received a VT during the follow-up period compared with children without a VT. CONCLUSION: HRQOL in children with otitis media was significantly improved after 13 months. The improvement in HRQOL was significantly lower for children with sleep problems. The improvement in HRQOL was significantly lower in children whose parents had been absent from work due to the child's otitis media. There were no statistically significant differences in the improvement of HRQOL in children who had received a VT during the follow-up period.
