Real requirements of nursing activities and patient-related factors related to nursing overload in an internal medicine department

Adequate nursing care can be decisive for the outcome of a patient admitted to an internal medicine ward. Individual prediction of nursing activity at the time of a patient’s admission could improve the work process. This study aimed to assess the objectively assessed nursing requirements of patients admitted to a medical setting and to identify clinical factors that correlate with high demands. This is a prospective and pragmatic observational study that enrolled patients admitted to the Internal Medicine ward at the Altovicentino Civil Hospital (Italy) between September 1 and December 31, 2022. Nursing activities were recorded for the first 3 days of hospitalization and standardized as performance/5 min/patient. Patients requiring more than the 75th percentile of performance/5 min/patient were considered nursing over-activities. Multivariable models were used to assess patient-related risk factors associated with nursing over-activity. This study enrolled 333 patients (mean age: 74.2; 55.6% male). Their mean Charlson Comorbidity Index (CCI), Clinical Frailty Scale (CFS), Chronic Barthel Index, and Sistema Informtativo della Performance Infermieristica (SIPI) scores were 5.3, 4.2, 62.4, and 53.7, respectively. Mean National Early Warning System (NEWS) on admission was 3.9 (standard deviation: 2.8). A median of 73 (interquartile range [IQR]: 54–109) nursing care activities/5 min/patient were performed. NEWS score (odds ratio [OR]: 1.372, 95% confidence interval [95%CI]: 1.216–1.547, p < 0.001) and Acute Barthel Index (OR: 0.983, 95%CI: 0.967–0.999, p = 0.041) were independent risk factors for nursing over-activities. NEWS and the Acute Barthel Index could help reorganize nursing resources within internal medicine wards, allowing for an equal distribution between patients who require more resources and those who require less.
