Delay in Transfer to Inpatient Stroke Rehabilitation: The Role of Acute Hospital Medical Complications and Stroke Characteristics

Inpatient Rehabilitation Care in Alberta: How Much Does Stroke Severity and Timing Matter?

BACKGROUND

We examined the impact of stroke severity and timing to inpatient rehabilitation admission on length of stay (LOS), functional gains, and discharge destination.

METHODS

Alberta inpatient stroke rehabilitation data between April 2013 and March 2017 were analyzed. We evaluated the impact of stroke severity, as measured by the Functional Independence Measure (FIM), on timing to inpatient rehabilitation, functional gains, LOS, and discharge destination. Further, we examined whether timing to inpatient rehabilitation impacted the latter three factors.

RESULTS

The 2404 adults were subcategorized as mild (1237), moderate (1031), or severe (136) based on FIM at inpatient rehabilitation admission. Length of time to rehabilitation admission was not significantly (p = 0.232) different between stroke severities. Mean length of time (days) to rehabilitation admission was 19.79 (20.3 SD) for mild, 27.7 (35.7 SD) for moderate, and 37.70 (56.8 SD) for severe stroke. Mean FIM change for mild (M = 16.3, 9.9 SD) differed significantly (p = 5.1 × 10-9) from moderate (M = 30.4, 16.4 SD) and severe (M = 31.0, 25.7 SD) stroke. The mean LOS for mild stroke (M = 41.3, 31.9 SD) was significantly (p = 5.1 × 10-9) different from moderate stroke (M = 86.8, 76.4 SD) and severe stroke (M = 126.1, 104.2 SD). Time to inpatient rehabilitation admission showed a small, significant impact on FIM change (p = 1.4 × 10-9, partial η2 0.022) and LOS (p = 1.1 × 10-19, partial η2 0.042). Shorter times to rehabilitation admission and mild stroke were associated with discharging home without needing homecare.

CONCLUSION

Stroke severity has a significant impact on the conduct of inpatient rehabilitation. Yet, despite suggestions shortening timing to rehabilitation should improve outcomes, the impact on functional gains and rehabilitation LOS was small.

[Risk factors for the onset of aspiration pneumonia among stroke patients in the recovery stage]

AIM

Post-stroke aspiration pneumonia is one of the most common complications among stroke patients. Although the onset of aspiration pneumonia is caused by a disruption of the balance between invasion (the type and amount of oral flora and aspiration) and host resistance (the protective airway reflex and immune function), several previous studies have focused on invasion, such as aspiration and dysphagia. In this study, we examined the importance of the host resistance to aspiration pneumonia among stroke patients with dysphagia.

METHODS

The study subjects included 76 stroke patients (mean age, 74.7±8.4 years) with dysphagia chosen from 175 stroke patients who were newly admitted to four rehabilitation hospitals. We divided the subjects into two groups based on the onset of pneumonia during the period of admission and compared their status.

RESULTS

Ten patients (13.2%) developed pneumonia at the hospital, and all of the affected patients were over 65 years old. Significant differences existed between the two groups with respect to the gender, activity level, albumin level, nutrition method and severity of dysphagia (p<0.05).

CONCLUSIONS

Our study revealed that recumbency, malnutrition, tube feeding, severe dysphagia and female sex were risk factors for pneumonia. In particular, dysphagia was closely associated with aspiration pneumonia. Moreover, host resistance factors, such as recumbency and malnutrition, also play important roles in the development of aspiration pneumonia.

Timing of inpatient rehabilitation initiation in stroke patients: factors influencing early admission

[Purpose] Early admission to inpatient rehabilitation is critical for reducing post-stroke disability. Assessing admission timing and other trends in inpatient rehabilitation are essential for improving health outcomes. This study is the first to evaluate the timing of admission of stroke patients to inpatient rehabilitation in Turkey. [Subjects and Methods] We retrospectively analyzed acute stroke survivors who were admitted to the inpatient rehabilitation program in the Ministry of Health, Ankara Physical Medicine and Rehabilitation Training and Research Hospital between January 2009 and December 2010. [Results] The mean onset of inpatient rehabilitation was 9.8 ± 6.7 weeks post-stroke in the entire cohort. Occurrence of ischemic stroke and undergoing acute stroke care at a teaching hospital were most strongly associated with early admission. These results did not change after multivariate analysis. [Conclusion] Turkish stroke survivors begin inpatient rehabilitation later than patients in other countries. The type of stroke and type of hospital in which the patient undergoes acute stroke treatment affects early admission.

Urinary tract infection after stroke

BACKGROUND

Urinary tract infection (UTI) is a recognized complication of stroke. We aimed to determine the incidence of UTI after acute stroke, the risk factors associated with this complication, and its association with outcome.

METHODS

Prospective study of consecutive acute stroke patients admitted to an urban teaching hospital. Routine clinical assessment included the modified National Institutes of Health Stroke Scale (mNIHSS) and modified Rankin scale (mRS). Patients were followed up for 3 months, including recording of clinician diagnosis of UTI.

RESULTS

We studied 412 patients; 65 (15.8%) were diagnosed with UTI, at a median of 14 days (IQR = 4-39) post-stroke. In a binomial multivariate regression analysis, UTI was associated with urinary catheterization (OR = 3.03, 95% CI 1.41-6.52), higher mRS (OR = 1.85, 1.29-2.64) and increasing age (OR = 1.51, 1.13-2.00 for each decade). UTI was associated with death or disability at 3 months, however, this link was attenuated and became non-significant when measures of stroke severity and pre-stroke morbidity were included in a multivariate analysis.

CONCLUSION

UTI is common after acute stroke. It is associated with urinary catheterization, post-stroke disability and increasing age. Avoidance of catheterization might reduce the incidence of this common complication.
