Electronic home monitoring of children with cystic fibrosis to detect and treat acute pulmonary exacerbations and its effect on 1-year FEV1

BACKGROUND

We aimed to investigate the effect of the use of electronic home spirometry in children with cystic fibrosis (CF) on 1-year FEV1 (% predicted, pp) change.

METHODS

This is a randomised, one-year prospective study including children with CF between 6 and 18 years of age. Subjects were randomised into home spirometry group (HSG) and usual care group (UCG). Children in HSG performed two pulmonary function tests (PFT) per week. Data regarding acute pulmonary exacerbations (PEx) was obtained from patients' records. At baseline and 12th month, health related quality of life questionnaire for CF patients (CFQ-R) and lung clearance index (LCI) were performed.

RESULTS

Sixty children were recruited with a median (IQR) age of 13.3 (11.4-15.4) years. Absolute change in FEV1pp from baseline to 12th month as median (IQR) was +1% (-6.75-9.75) in HSG and -2.50% (-7.50-3.25) in UCG (p = 0.10). Sensitivity analysis including only adherent children in HSG (n = 22), yielded an increase of 5% (-3.50-12) in HSG and a decrease of 2.50% (-7.50-3.25) in UCG (p = 0.009). A total of 29 (96.7%) subjects in HSG and 23 (76.7%) in UCG had PEx (p = 0.05). Absolute change in median (IQR) LCI2.5 from baseline to the 12th month was -1.6 [-2.9-0] (p<0.001) in HSG and -1.5 [-2.8-(-0.6)] (p<0.001) in UCG (p = 0.94). There was a significant increase in the social domain of the CFQ-R in HSG (from 59.1 to 76.2, p = 0.01).

CONCLUSIONS

Electronic home monitoring of children with CF by spirometry may result in improvement in lung function.

Is the Pediatric Sleep Questionnaire sensitive for sleep-disordered breathing in children with complex chronic disease?

PURPOSE

Sleep-disordered breathing (SDB) is a disease defined by breathing or breathing irregularities while asleep. The current study examines the association between results of polysomnography (PSG) and the Pediatric Sleep Questionnaire (PSQ), and the specificity and sensitivity of the PSQ for obstructive sleep apnea (OSA) in patients with chronic illnesses.

METHODS

Demographic and clinical attributes, in addition to PSQ and PSG outcomes were examined retrospectively among patients who underwent polysomnography (PSG) at our facility between 2012 and 2021.

RESULTS

Of 745 patients included in the study, 462 (62%) were male. The median age was 81 months (34-151 months). 117 of the patients (15/8%) had chronic lung disease, and 80 (10.7%) had cerebral palsy. The most common indications for PSG were symptoms of OSA (n = 426; 57.1%). According to obstructive apnea-hypopnea index (AHI), 361 patients (48.5%) had normal PSG. The median PSQ score was 0.40 (0.22-0.57). The sensitivity and specificity of the PSQ were 71.8% and 40.4%, respectively, for individuals aged 2 to 18 years. Among the disease subgroups, the cerebral palsy group had the highest sensitivity of PSQ (88.8%) for diagnosis of OSA.

CONCLUSION

Questionnaires for evaluating SDB are not sensitive or specific for identification of OSA in children with chronic conditions, and PSG remains the best method.

Long-term outcomes of standardized training for caregivers of children with tracheostomies: The IStanbul PAediatric Tracheostomy (ISPAT) project

BACKGROUND AND OBJECTIVES: Children with tracheostomies are at increased risk of tracheostomy-related complications and require extra care. Standardized training programs for caregivers can improve tracheostomy care and reduce complications. In this study, we compared caregiver knowledge and skill scores after a standardized theoretical and practical training program on tracheostomy care (IStanbul PAediatric Tracheostomy (ISPAT) project) immediately and 1 year post-training and evaluated how this training affected the children's clinical outcomes.

MATERIALS AND METHODS

We included 32 caregivers (31 children) who had received standardized training a year ago and administered the same theoretical and practical tests 1 year after training completion. We recorded tracheostomy-related complications and the number and reasons for admission to the healthcare centers. All data just before the training and 1 year after training completion were compared.

RESULTS

After 1 year of training completion, the median number of correct answers on the theoretical test increased to 16.5 from 12 at pretest (p < 0.001). Compared with pretest, at 1-year post-training practical skills assessment scores, including cannula exchange and aspiration, were significantly higher (both p < 0.001) and mucus plug, bleeding, and stoma infection reduced significantly (p = 0.002, 0.022, and 0.004, respectively). Hands-on-training scores were better than pretest but declined slightly at 1 year compared to testing immediately after training. Emergency admission decreased from 64.5% to 32.3% (p = 0.013). Hospitalization decreased from 61.3% to 35.5% (p = 0.039).

CONCLUSION

Our findings indicate that caregiver training can lead to a persistent increase in knowledge and skill for as long as 1 year, as well as improvements in several measurable outcomes, although a slight decrease in scores warrants annual repetitions of the training program.

Implementation of standardized cystic fibrosis care algorithm to improve the center data-quality improvement project international collaboration

BACKGROUND

A collaboration between the University of Michigan (U of M) Cystic Fibrosis Center (CFC) and Marmara University (MU) CFC was initiated to improve the health status of people with cystic fibrosis (pwCF) at MU through implementing Quality Improvement (QI) initiatives. The main aim was to improve lung function in children with FEV1pp <80. The secondary aim was to assess the changes in health related quality of life.

METHODS

Included in the project were pwCF who received cystic fibrosis (CF) care at the MU CFC and were 6-18 years of age with an FEV1pp <80. Flow charts were created and a standardized CF care algorithm was implemented. Weekly case review were done to develop individualized treatment plans. Appropriate intervention was applied and patient data were assessed at baseline, 3, 6, 9 and 12 months. The Cystic Fibrosis Revised Questionnaire (CFQ-R) was completed.

RESULTS

55 pwCF were included (mean age:11.8 ± 3.3 years). Mean FEV1pp (SD) at baseline, 6 and 12 month was 63.7 (14.6), 66.9 (16.6), 70.4 (19.2), respectively, with a relative increase of 5.0% in 6 months (p:0.002) and 10.5% in 12 months compared to baseline (p<0.001). Physical functioning, eating problems and respiratory symptoms domains of the CFQ-R questionnaire were improved at the end of the one year for 6-13 (p = 0.024, p = 0.009, p = 0.002) and 13-18 year olds (p = 0.013, p = 0.002, p = 0.038).

CONCLUSION

There was significant improvement in pwCF with FEV1<80%pp after implementing this QI project. The processes and assessments used can be adopted by other low-middle income countries to improve similar measures.

Improvements in body mass index of children with cystic fibrosis following implementation of a standardized nutritional algorithm: A quality improvement project

BACKGROUND

A collaboration between the University of Michigan (UM) Cystic Fibrosis Center (CFC) and Marmara University (MU) CFC was initiated in MU through conducting Quality Improvement projects (QIP). The global aim was to improve nutritional status of children with CF (cwCF), with a specific aim to increase the mean BMI percentile (BMIp) for cwCF by 10 percentile points in 12 months.

METHODS

Body mass index (BMI) percentiles of cwCF were categorized as: nutritionally adequate (BMIp ≥ 50%); at risk (BMIp 25%-49%); urgently at risk (BMIp 10%-25%); critically at risk (BMIp < 10%). Appropriate interventions were made according to BMIp category every three months. Forced expiratory volume in one-second percent predicted (FEV1pp), and health-related quality of life (HRQoL) were evaluated.

RESULTS

One hundred and eight-two cwCF with a mean age of 9.1 ± 4.3 years were included in the project. Baseline BMIp increased from 25.6 to 37.2 at the 12th month (p < 0.001). In the critically at-risk group BMIp increased from 3.6 to 20.5 (p < 0.001), in the urgently at risk group from 15.9 to 30.8 (p < 0.001), in the at risk group from 37.0 to 44.2 (p < 0.079) and in the nutritionally adequate group the increase was from 66.8 to 69.5 (p < 0.301). FEV1pp also improved significantly, from 81.3 ± 20.6 to 85.9 ± 20.8 (p < 0.001). Physical functioning, eating problems, and respiratory symptoms domains of the HRQoL evaluation improved (p < 0.05).

CONCLUSION

This project has led to significant improvements in BMIp, FEV1pp and HRQoL of cwCF; similar projects could easily be implemented by centers in other developing countries.

The effect of coronavirus disease 2019 on anxiety levels of children with cystic fibrosis and healthy peers

BACKGROUND

Cystic fibrosis (CF) is a chronic disease causing recurrent respiratory tract infections. Viral respiratory tract infections are more severe in CF. The first case of coronavirus disease 2019 (COVID-19) was seen in Turkey on March 11, 2020, and nationwide school closure and lockdown were implemented. School closure and home confinement might have adverse effects on children's physical and mental health. In this study, we aimed to compare the effect of the COVID-19 pandemic on psychological reactions of CF patients and healthy controls.

METHODS

This is a controlled cross-sectional study including 7-18-year-old children with CF. The survey included questions regarding family environment and peer relations, self-care, and psychological reactions to the COVID-19 pandemic. The questionnaire was administered to children via telephone calls under parental supervision.

RESULTS

We evaluated 132 CF patients and 135 of their healthy peers. Mean age was 11.5 ± 2.9 years in the CF group and 11.8 ± 3.2 years in the control group (P = 0.98). There were 55 girls (41.7%) in the CF group and 81 girls (60%) in the control group (P = 0.027). The socioeconomic status of their families was similar. The CF patients were found to be less anxious for family members at risk of COVID-19, less upset about school closure, and less anxious about the COVID-19 pandemic (P < 0.001, 0.02, 0.01, respectively).

CONCLUSIONS

Cystic fibrosis patients seem to show more resilience in coping with the pandemic. Appropriate psychological support should be provided to them and resilience strategies in coping with the pandemic should be nurtured.
