- Other: Video-assisted trainingOther: Nurse training
- Registration Number
- NCT06507098
- Lead Sponsor
- Consorci Sanitari del Maresme
- Brief Summary
The objective of this trial is to evaluate the use of a video-assisted training for the use of a home-respiratory polygraph for the diagnosis of obstructive sleep apnea compared to standard training by a nurse.
A clinical trial is conducted to this effect. One arm is video-assisted training and the other arm is conventional training by a nurse.
- Detailed Description
Hypotheses:
1. The use of a video for the correct performance of home respiratory polygraphy (RP) reduces the number of errors derived from poor placement of the polygraph.
2. The degree of satisfaction of telematic instruction will be higher than that of in-person instruction.
3. Telematic instruction will achieve a reduction in care time allocated to instruction for the nursing staff of the Pneumology Day Hospital.
Objectives:
Main objective:
Compare the number of errors in the RP record derived from poor placement of the polygraph between an in-person nursing instruction and a telematic instruction using a video.
Secondary objectives:
* Compare the number of total errors in the RP record between an in-person nursing instruction and a telematic instruction using a popular video.
* Compare the level of patient satisfaction between in-person nursing instruction and telematic instruction using a video.
* Compare the time invested in nursing at the Pneumology Day Hospital in the delivery and instruction of polygraph use between in-person instruction and telematic instruction.
Study design:
Open randomized clinica trial with two arms of intervention: instruction in the functioning of the respiratory polygraph according to usual clinical practice and instruction in audiovisual media.
Study population Patients with suspected Obstructive sleep apnea (OSA) who have been indicated for performing a home respiratory polygraphy for the first time.
Study exhibition Consecutive patients with OSA who come to the Pneumology Service for the collection of a respiratory polygraph for the performance of a home PR for the first time. Recruitment is made at the time you go to collect the respiratory polygraph if you decide to participate in the study, after signing the informed consent and checking the inclusion and exclusion criteria. At that moment randomization will be made and they will be assigned to one of the two intervention groups.
Statistical analysis
The data will be registered in an electronic data base in a dissociated manner so that the analyzers will not be able to connect the identity of the persons participating in the study. The database will be stored in the CSdM information system along with standard security measures. The analysis plan includes:
1. Description of the main characteristics of the study sample (age, gender, participation of a third person, number of views, etc.) including values and typical deviations for numerical variables and percentages for categorical variables.
2. Assessment of the homogeneity and/or comparability of the two study groups. The categorical variables are compared using the Khi al quadrat test or the Fisher exact test and the numerical variables with the T-Student test or the Man Whitney U test.
3. Comparison of the main results measures (percentage of valid PRs, number of errors, satisfaction, investment times) between the two study groups using the same statistical tests as in the previous section.
4. Description of the main causes of error with percentage percentages for each of the identified causes.
5. Evaluation of the factors associated with an invalid RPR using the statistical tests previously carried out and estimating the corresponding OR and the six 95% confidence intervals (95% CI) using bivariate and multivariate logistic regression (to adjust for possible risk factors). confused)
6. Assessment of secondary objects. In all statistical analyses, a statistical significance level of 0.05 will be considered.
