Structured Nursing Intervention for Adults With Poorly Controlled Asthma: A Pilot Study (RESPiraIA-Asma)

June 3, 2026 updated by: Elena Fariñas Álvarez, Hospital San Carlos, Madrid

Design and Development of RESPiraIA-Asthma: A Structured Nursing Intervention for the Follow-up of Adults With Poorly Controlled Asthma. A Pilot Study

Asthma affects a large number of adults, and many of them do not achieve good control of their symptoms. Poor inhaler technique, irregular medication use, and the lack of structured nursing follow-up are among the main reasons. RESPiraIA-Asma is a 12-month structured nursing intervention designed to address these gaps in adults with poorly controlled, non-severe asthma.

This is a quasi-experimental, single-group, before-and-after pilot study. Each participant is followed across six visits over one year, at baseline and at months 1, 3, 6, 9, and 12. The intervention combines therapeutic education, inhaler technique training, home peak-flow self-monitoring, biopsychosocial assessment, and a standardized nursing care plan based on internationally recognized nursing taxonomies for diagnoses, interventions, and outcomes: NANDA International (NANDA-I), Nursing Interventions Classification (NIC), and Nursing Outcomes Classification (NOC), activated by objective clinical thresholds.

A central principle of the model is digital equity: the same standard of care is offered through three equivalent access routes (digital, mixed, or in-person), chosen according to each participant's digital skills, resources, and preferences, so that technology never becomes a barrier to access.

The study evaluates whether the model is feasible to deliver in routine clinical practice, measured through participant retention, data completeness, and acceptability, and it looks for preliminary signals of its effect on asthma control, treatment adherence, lung function, and biopsychosocial well-being. As an exploratory pilot, it is not designed to confirm efficacy; its purpose is to inform the design of a larger future trial.

Intervention / Treatment

Detailed Description

RESPiraIA-Asma is the first pilot application of the RESPiraIA model, a structured nursing intervention built on three operational cores. The administrative core covers governance and digital equity through three equivalent access routes (digital, mixed, and in-person). The clinical core triangulates asthma control and treatment adherence using three validated instruments: the Asthma Control Test (ACT) for clinical control, the Test of Adherence to Inhalers (TAI) for self-reported adherence, and the Medication Possession Ratio (MPR) for objective adherence from pharmacy dispensing, with automatic calculation of the discrepancy between self-reported and objective adherence as an active clinical indicator. The nursing core delivers a standardized care plan based on internationally recognized nursing taxonomies for diagnoses, interventions, and outcomes: NANDA International (NANDA-I), Nursing Interventions Classification (NIC), and Nursing Outcomes Classification (NOC), activated by objective clinical thresholds.

The study sits within the development and feasibility phases of the Medical Research Council (MRC) framework for complex interventions. It is not a confirmatory efficacy trial; the clinical outcomes are evaluated as preliminary signals intended to inform the design of a future multicentre confirmatory trial. Pre-pilot functional verification of the data capture system, REDCap (Research Electronic Data Capture), was carried out using systematic synthetic profiles before the start of recruitment.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: RESPiraIA-Asma structured nursing intervention
Single experimental arm: all enrolled participants receive the RESPiraIA-Asma intervention, with no control group, and comparisons are within-subject (baseline versus month 12). Follow-up lasts 12 months across six visits (baseline and months 1, 3, 6, 9, and 12). Each participant is assigned to one of three equivalent access modalities (digital, mixed, or in-person) according to digital competence, internet access, available devices, and preference. The clinical content is identical across modalities, and participants may switch modality during follow-up if their circumstances change.
Structured nursing intervention of 12 months organized in three operational cores (administrative, clinical, and nursing) and delivered across six visits. It combines therapeutic education, inhaler technique training with the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR) checklist, home peak-flow self-monitoring, biopsychosocial assessment, and a standardized care plan based on the NANDA International (NANDA-I), Nursing Interventions Classification (NIC), and Nursing Outcomes Classification (NOC) taxonomies, activated by objective clinical thresholds. Treatment adherence is monitored through the triangulation of the Asthma Control Test (ACT), the Test of Adherence to Inhalers (TAI), and the Medication Possession Ratio (MPR). Follow-up and the deterministic care logic run in REDCap (Research Electronic Data Capture).

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in asthma control measured by the Asthma Control Test (ACT)
Time Frame: Baseline, month 6, month 9, and month 12
Asthma control assessed with the Asthma Control Test (ACT), a 5-item questionnaire scored from 5 to 25. The main analysis is the within-subject change from baseline to month 12, with a minimal clinically important difference of at least 3 points. The ACT is also the continuous variable used for the sample size calculation.
Baseline, month 6, month 9, and month 12
Change in objective treatment adherence measured by the Medication Possession Ratio (MPR)
Time Frame: Baseline, month 1, month 6, month 9, and month 12
Objective adherence to inhaled maintenance therapy, calculated from pharmacy dispensing records as medication dispensed divided by medication prescribed, expressed as a percentage. A value of at least 80% is considered adequate. In participants with recent treatment initiation (less than 6 months), the ratio is not computable at baseline and adherence is assessed through the Test of Adherence to Inhalers (TAI) and inhaler technique.
Baseline, month 1, month 6, month 9, and month 12
Change in self-reported treatment adherence measured by the Test of Adherence to Inhalers (TAI)
Time Frame: Month 1, month 6, month 9, and month 12
Self-reported adherence assessed with the Test of Adherence to Inhalers (TAI), a 12-item questionnaire; a score of at least 50 indicates good adherence. It is first administered at month 1 because it evaluates adherence behaviour over a prior treatment period, not applicable at baseline.
Month 1, month 6, month 9, and month 12

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change in lung function (forced expiratory volume in the first second, FEV1)
Time Frame: Baseline, month 6, and month 12
Lung function measured by spirometry and expressed as the forced expiratory volume in the first second (FEV1) as a percentage of the predicted value.
Baseline, month 6, and month 12
Change in inhaler technique
Time Frame: Baseline, month 3, month 6, and month 12
Inhaler technique assessed by direct observation using the 8-step checklist of the Spanish Society of Pulmonology and Thoracic Surgery (SEPAR), recorded as the number of correctly performed steps out of 8.
Baseline, month 3, month 6, and month 12
Change in emotional health (Hospital Anxiety and Depression Scale, HADS)
Time Frame: Month 1 and month 9
Emotional health assessed with the Hospital Anxiety and Depression Scale (HADS), with anxiety and depression subscales each scored from 0 to 21. Change analysed from month 1 to month 9.
Month 1 and month 9
Change in dietary habits (PREDIMED Mediterranean diet adherence questionnaire)
Time Frame: Month 1 and month 9
Adherence to the Mediterranean diet assessed with the 14-item PREDIMED questionnaire; a score of at least 9 indicates good dietary adherence. Change analysed from month 1 to month 9.
Month 1 and month 9
Change in health-related quality of life (EuroQol-5D-5L, EQ-5D-5L)
Time Frame: Baseline and month 12
Health-related quality of life assessed with the EuroQol-5D-5L (EQ-5D-5L), covering five health dimensions with five severity levels each, plus a visual analogue scale.
Baseline and month 12
Change in asthma knowledge (RESPiraIA-Knowledge questionnaire)
Time Frame: Baseline and month 12
Functional knowledge about asthma and its management assessed with the RESPiraIA-Knowledge questionnaire, a 12-item instrument developed for this study, content-validated by an expert panel (scale-level content validity index, average, of 0.97).
Baseline and month 12
