A survey of the physiotherapy treatment methods for infants hospitalised with acute airway infections in Sweden

The Use of Evaluation Methods for Physiotherapy Treatment in Infants With Bronchiolitis-a Survey Study

AIMS

The aim of this study was to identify and describe methods that physiotherapists use to evaluate the immediate effects of their interventions for infants in hospital with acute respiratory tract infections.

METHODS

We constructed an anonymous digital survey to physiotherapists working with infants aged 0-24 months in Sweden. The survey was distributed by e-mail and posted on web pages for seven weeks, which included a reminder.

RESULTS

Replies were obtained from 88 respondents, and 52 completed surveys remained to be analyzed. All 21 counties in Sweden were represented. The most prevalent answer options were as follows: more productive/increased or decreased cough (73%), increased oxygen saturation (35%), changed secretion sounds (33%), reduced work of breathing (20%), and parental report (16%).

CONCLUSIONS

The physiotherapists reported to use diverse methods for evaluation of their interventions. However, to a large degree they used subjective measures, which depend on the individual clinician's assessment and interpretation. The evaluation methods vary in psychometric properties and robustness. This study identifies the need for consensus about valid, reliable, and clinically relevant evaluation methods for this patient group.

Frequent body position changes and physical activity as effective as standard care for infants hospitalised with acute respiratory infections - a randomised controlled trial

Background

No definite consensus has been reached yet on the best treatment strategy for the large group of infants hospitalised with bronchiolitis or pneumonia. Minimal handling is often recommended, although not evaluated scientifically. There is a need to evaluate the management, as the infants often are critically affected, and the costs for society are high. The aim of this RCT was to evaluate the most common physiotherapy intervention in Sweden for this patient group, including frequent changes in body position and stimulation of physical activity, compared to standard care.

Methods

Infants 0-24 months old, without previous cardiac or respiratory diagnoses and born in gestational week 35+, were recruited in two Swedish hospitals. The participants (n=109) were randomised to either interventions in addition to standard care (intervention group) or to standard care alone (control group). The primary outcome measure was time to improvement. The secondary outcomes were immediate changes in oxygen saturation, heart rate and respiratory rate, time to improved general condition (parents' assessment), and lung complications.

Results

The median time to improvement was 6 hours in both groups (p=0.54). The result was similar when we adjusted for age in months, sex, tobacco smoke exposure, heredity for asthma/atopic disease, and early stage of the infection (for those with RSV), p=0.69. Analyses of the immediate changes showed no significant differences either (p=0.49-0.89). Time to improved general condition was median 3 hours in the intervention group and 6 hours in the control group, p=0.76. No lung complications occurred.

Conclusions

No statistically significant differences in outcomes were detected between the intervention group and the control group. Both strategies were found to be equally effective and safe, indicating that the current recommendation of minimal handling for these infants should be reconsidered. Furthermore, the findings suggest that this treatment can be safely continued.

Physiotherapy interventions encouraging frequent changes of the body position and physical activity for infants hospitalised with bronchiolitis: an internal feasibility study of a randomised control trial

Background

The effect of a treatment that includes frequent changes of the body position for infants with bronchiolitis has not been evaluated, although it is often used in Swedish hospitals. Because of this, a randomised control trial (RCT) has begun with the aim to evaluate this treatment, comparing the effect of an individualised physiotherapy intervention, a non-individualised intervention, and standard care in a control group. The objective of this internal pilot study was to address uncertainties concerning the ongoing RCT and to determine whether the trial is feasible or not, possibly with adjustments to the protocol.

Methods

Descriptive analyses of the recruitment, retention, data supply for the primary end point, and the usability of the primary outcome measure in the full RCT were performed. A safety analysis was conducted by an independent analysis group.

Results

Ninety-one infants were included, 33 (36.3%), 28 (30.8%), and 30 (33.0%) in the respective allocation groups. Fifty-nine (64.8%) were boys. The median age was 2.5 (min–max 0.2–23.7) months. They remained in the study for a median of 46 hours (min–max 2–159). The recruitment rate was 19%. The data supply for the primary end point and for the primary outcome measure was lower than anticipated in the original sample size calculation. Difficulties concerning utilising the primary outcome measure were identified. The safety analysis detected no risks of harm related to participation in the study.

Conclusions

It is feasible to continue the RCT with modifications of the analysis plan. Participation in the study was not associated with any safety risks.

The effect of physiotherapy including frequent changes of body position and stimulation to physical activity for infants hospitalised with acute airway infections. Study protocol for a randomised controlled trial

Background

Every year, many infants are infected with the respiratory syncytial virus (RSV) or other agents and need hospitalisation due to bronchiolitis. The disease causes much suffering and high costs. Thus, it is important that the treatment methods are both effective and cost-efficient. The use of different physiotherapy treatment methods is debated, and not all methods are evaluated scientifically. The clinical praxis in Sweden that includes frequent changes of body position and stimulation to physical activity has not previously been evaluated. The aim of this clinical study is to evaluate this praxis.

Methods

This study is a clinical two-centre individually randomised controlled trial (RCT) with three parallel groups. The participants will be randomly assigned to an individualised physiotherapy intervention, a non-individualised intervention, or a control group. All three groups will receive the standard care at the ward, and the two intervention groups will receive additional treatment, including different movements of the body. The primary outcome measure is a clinical index based on determinants for hospitalisation. Baseline assessments will be compared with the assessments after 24 h. The secondary outcome measures include vital signs, the parents’ observations, time spent at the hospital ward, and referrals to an intensive care unit. We also want see if there is any immediate effect of the first intervention, after 20 min.

Discussion

This study will add knowledge about the effect of two physiotherapy interventions that are commonly in use in Swedish hospitals for infants with bronchiolitis or other acute lower respiratory tract infections.
