Clinical validation of the related factors and defining characteristics of impaired swallowing for patients with stroke

Content validation of the defining characteristics of the nursing diagnosis "impaired swallowing" using the Delphi technique: A study with dysphagia nursing experts in Japan

PURPOSE

Nurses' clinical reasoning skills regarding impaired swallowing can help prevent patient complications and maintain quality of life. Clinical reasoning skills need content-validated defining characteristics (DCs). We aimed to validate the content of these DCs for nursing diagnosis "impaired swallowing."

METHODS

Content validation of the DCs was performed by 275 dysphagia nursing experts in Japan, using 3 rounds of the Delphi technique and Fehring's Diagnostic Content Validation (DCV) model. Three rounds of questionnaires on 84 DCs were completed via printed mail.

FINDINGS

The valid response rates for each round were as follows: round 1, 90.2%; round 2, 77.8%; and round 3, 71.3%. Of the 84 DCs, 77 that met the consensus criteria were categorized as major (n = 18), minor (n = 45), and excluded (n = 14). There were four minor DCs other than the oral, pharyngeal, and esophageal phases. DCs listed from outside NANDA-I included 12 major, 16 minor, and 3 excluded characteristics. Of the NANDA-I DCs, 5 were no consensus and 11 were excluded. The total DCV score for the 63 major and minor DCs was 0.8.

CONCLUSIONS

Our results recommend the addition of 28 DCs and the exclusion of 11 for the NANDA-I nursing diagnosis "impaired swallowing" (00103). Major DCs were prominent indicators of impaired swallowing and signs of aspiration or pharyngeal residuals. Minor DCs included not only the three phases but also other signs necessary for a comprehensive understanding of impaired swallowing.

IMPLICATIONS FOR NURSING PRACTICE

This validation study strengthens the clinical usefulness of the DCs for impaired swallowing, which can improve nurses' clinical reasoning skills. Major and minor DCs can increase the awareness of impaired swallowing and enable accurate intervention, thereby preventing patient complications and maintaining quality of life.

Effects of Support Interventions in Women Hospitalized With Preterm Labor

This study was to examine the effects of support interventions on anxiety, depression, and quality of life in women hospitalized with preterm labor. A randomized, single-blind experimental design was used. Participants were recruited from maternity wards of one medical center in Taiwan. The control group ( n = 103) received routine nursing care, and intervention group ( n = 140) received interventional support during hospitalization. The Beck Anxiety Inventory, Edinburgh Postnatal Depression Scale, and Quality of Life Enjoyment and Satisfaction Questionnaire were used at admission and 2 weeks of hospitalization. For the control group, anxiety and depression scores increased significantly and quality of life decreased 2 weeks after hospitalization. Participants who received 2 weeks of support intervention had significantly lower anxiety and depression scores than controls. Thus, clinical nurses can offer support interventions to improve anxiety and depression for women with preterm labor during hospitalization.
