Home care of adults with a tracheostomy places a substantial burden on family members, as it encompasses emotional, educational, social, and structural domains. One of the main challenges is emotional overload, which includes anxiety, fear, and uncertainty regarding the responsibility of tracheostomy management, particularly during the transition period from hospital to home (1–4).

Likewise, deficiencies have been identified in the education provided to caregivers for tracheostomy management, which is often insufficient to address complex situations such as emergencies or specific techniques such as tracheal suctioning. This affects perceived confidence and safety when assuming care (5,6).

Other relevant challenges include difficulties in accessing and coordinating resources, such as obtaining medical supplies or support from home nursing services, compounded by the lack of standardization in care (5,7). The caregiving experience itself also affects quality of life and family functioning, as it disrupts sleep, limits social and work life, and creates isolation (2,3). Added to this is a perception of limited professional and social support, especially after hospital discharge (1,7,8).

Training caregivers of persons with a tracheostomy improves their knowledge, confidence, and skills to manage equipment, which can help reduce complications and enables a safer transition to the home (9,10). Standardized programs have been shown to reduce adverse events, such as infections and hospital readmissions (11). Some clinical guidelines recommend including hands-on training and validating skills to promote a safe home environment (12,13).

From a psychosocial perspective, caregiver self-efficacy is a central construct grounded in Bandura’s social cognitive theory (14) and refers to the perceived capability to perform specific behaviors in demanding situations. In the context of home tracheostomy care, adequate self-efficacy is associated with greater adherence to care and better performance of procedures (15).

On the other hand, regarding complications that most frequently occur at home, tube obstruction, accidental displacement, local and respiratory infections, and device malfunction have been described, and to a lesser extent, bleeding and complications related to tracheal structure (16,17). Having a rubric to assess potential complications that an adult with a tracheostomy may develop would help caregivers identify them in a timely manner.

In the literature review for this study, no validated instruments were identified to structurally assess caregivers’ knowledge and self-efficacy for performing specific procedures. These include oral and tracheostomy secretion suctioning, proper cleaning of materials, cleaning of the tracheostomy tube and inner cannula, stoma care, recannulation after accidental decannulation, and identification of complications.

Therefore, the aim of this study is to design and obtain the content validity coefficient (CVC) of two questionnaires—one assessing knowledge of home tracheostomy management and the other assessing self-efficacy for its management—as well as two clinical rubrics to identify early and late complications in persons with a tracheostomy.

These instruments constitute a tool for the training, monitoring, and evaluation of professional caregivers or family caregivers of adults with a tracheostomy. Likewise, they are useful tools for planning personalized educational interventions.

Informed consent was obtained from all participating experts, and the study was conducted in accordance with the principles of the Declaration of Helsinki, respecting confidentiality and voluntary participation. No participation from patients or caregivers was included, as the aim was solely to obtain the CVC of the instruments through expert judgment.

The results of the design and the CVC of the knowledge and self-efficacy questionnaires for home tracheostomy management, as well as the two clinical rubrics for identifying early and late complications in individuals with tracheostomies, are presented (Tables 1 and 2).

Six questions were removed from the questionnaire due to their complexity and redundancy, based on the experts' observations. These included items on the cleaning of the inner cannula, reinsertion after decannulation, and complications such as the tracheoesophageal fistula.

In the self-efficacy questionnaire, four items were removed due to redundancy or low relevance, according to the experts. These items addressed stoma care, respiratory observation, detection of complications, and materials management (Table 3).

Regarding the Early Complications Identification Rubric, criterion 6 was removed as the experts identified it as repeated and redundant in relation to other evaluated criteria.

Both the questionnaires and the rubrics achieved CVC values greater than 0.90, surpassing the minimum cutoff of 0.80 set by Hernández-Nieto (18). Moreover, all items included in the final versions reached CVC values > 0.80, and the items eliminated were based on complexity, repetition, redundancy, or low relevance, as assessed by the experts.

Technical or ambiguous terms such as "most appropriate position," "accidental decannulation," or "stable patient" were identified as potentially unclear for family caregivers, and suggestions were made to replace them with more accessible expressions.

Additionally, questions with confusing wording or unclear sequences of actions were noted, such as those related to suction catheter use and securing the cannula. The experts also recommended clearer formulations. Furthermore, they advised specifying certain answers, such as the type of cloth or the use of hydrogen peroxide for cannula cleaning. All observations were considered, and necessary adjustments were made, improving the wording and adapting the content to the comprehension level of family caregivers, which strengthened both the questionnaires and rubrics.

In the home care of patients with tracheostomies, it is crucial to have validated instruments to assess caregivers' knowledge and self-efficacy. The results from the design and validation of the two questionnaires and two rubrics show high content validity, supporting their usefulness for evaluating knowledge, self-efficacy, and complications in home tracheostomy management. Furthermore, they constitute valid tools for assessing preparation and confidence regarding complex procedures and emergencies, especially considering that many caregivers undertake these tasks without formal healthcare training (36-38).

The preparation of those involved in home tracheostomy management is vital, and this is supported by studies by Amar-Dolan et al. (5) and Yilmaz Yegit et al. (9), which have shown that structured caregiver training significantly improves their confidence and skills, thereby reducing adverse events such as infections and hospital readmissions. In this sense, the questionnaires from this study not only help identify educational deficiencies but also measure self-efficacy perception, offering a comprehensive view in training processes.

Regarding the clarity and relevance of the items, the adjustments made based on the experts' observations, particularly concerning technical language, reinforce the need to adapt the instruments to the target population defined for this study, i.e., family caregivers. This ensured that the items were understandable and relevant for their future application, as stated by Kasper et al. (39).

In adults with home tracheostomies, the most common complications include tube obstruction, displacement, infections, and device failures, with acute obstruction being a frequent emergency (13,40). Long-term complications, such as tracheal stenosis and tracheomalacia, may also arise (17). In this context, the inclusion of clinical rubrics provides more objective and structured assessment tools for recognizing complications. Having these rubrics facilitates the early (early complications) and late identification of adverse events, improving decision-making at home; it also serves as an evaluation tool that would support new interventions and contribute to safer care in the home setting.

The methodology used allowed the assessment of the CVC of the instruments through expert judgment in critical care, home care, and teaching. The main limitations include the absence of empirical validation with the target population and the limited size of the expert panel. Therefore, it is recommended to plan subsequent studies for construct validation, criterion validation, and reliability analysis through pilot tests with family caregivers .

This study allowed for the methodological design, refinement, and obtaining of the Content Validity Coefficient (CVC) through expert judgment for four instruments focused on the home care of adults with tracheostomies: two questionnaires (knowledge and self-efficacy) and two clinical rubrics for identifying early and late complications. As a result of the CVC process, the final versions of the instruments were consolidated, retaining only the items and clinical criteria with adequate clarity, relevance, and pertinence, supported by CVC values greater than 0.90.
