Nursing diagnoses and hospital readmission of patients with respiratory diseases: Findings from a case-control study.

This was a single-hospital case-control study using existing electronic records, so the associations may not apply to other settings or patient groups. Cases and controls were not matched, and the analysis could not rule out residual confounding from factors not recorded. The study relied on electronic nursing records, and the authors say it is unknown whether nursing diagnoses were assigned with enough rigour. Nurse documentation workload may have affected record quality. Important social and follow-up information, including community continuity of care, was not available. The study found associations, not proof that treating these nursing diagnoses prevents readmission.

The study was funded by a grant from the Official College of Nursing of Asturias. The funder had no role in study design, data analysis, interpretation, writing, or submission. The authors declared no conflicts of interest.

Do not conclude that these nursing diagnoses cause readmission or that treating them will prevent readmission. This was an observational case-control study, and the associations may reflect patient complexity, comorbidity, or documentation differences rather than a proven effect.
