Length of Stay and Functional Outcomes Among Patients with Stroke Discharged from an Inpatient Rehabilitation Facility in Saudi Arabia

Differences in factors associated with stair-climbing ability at discharge based on the severity of lower limb paralysis in patients with stroke

BACKGROUND

Obtaining stair-climbing ability at discharge is crucial, and identifying the predictors of independent stair-climbing ability is important for making rehabilitation more effective.

OBJECTIVES

This study aimed to clarify the factors associated with stair climbing at discharge in patients with stroke classified according to the severity of lower limb paralysis.

METHOD

This study is a multi-institutional retrospective observational study included patients with acute ischemic stroke and intracerebral hemorrhage. Patients were classified into the severe group and the mild groups based on the severity of their lower limb function. Multiple logistic regression analysis was performed for all included patients and each severity group to investigate factors associated with stair-climbing ability at discharge.

RESULTS

We included 2,097 patients (41.5 % female) with a median age (interquartile range) of 75 (66-83) years in the present analysis. Overall, 105 (19.6 %) patients in the severe group were able to stair climbing independently and 1,069 (68.5 %) in the mild group were able to climb stairs independently. Predictors independently associated with stair-climbing ability in the severe group included age, paralyzed side, sitting ability, acute length of stay (acute LOS), and functional independence measure (FIM) motor items. Predictors in mild group were age, stroke type, upper limb function, sitting ability, acute LOS, FIM motor, FIM cognitive.

CONCLUSIONS

The predictors of stair-climbing ability differed according to the severity of lower limb paralysis. The results of this study can be used to predict the prognosis of stair-climbing ability to support goal setting and decision-making in rehabilitation treatment.

Which items of the modified Barthel Index can predict functional independence at discharge from inpatient rehabilitation? A secondary analysis retrospective cohort study

The modified Barthel Index (mBI) is a well-established patient-centered outcome measure commonly administrated in rehabilitation settings to evaluate the functional status of patients at admission and discharge. This study aimed to detect which mBI items collected on admission can predict the total mBI at discharge from first inpatient rehabilitation in large cohorts of orthopedic (n = 1864) and neurological (n = 1684) patients. Demographic and clinical data (time since the acute event 11.8 ± 17.2 days) at patients' admission and mBI at discharge were collected. Univariate and multiple binary logistic regressions were performed to study the associations between independent and dependent variables for each cohort separately. In neurological patients, the shorter time between the acute event and rehabilitation admission, shorter length of stay, and being independent with feeding, personal hygiene, bladder, and transfers were independently associated with higher total mBI at discharge (R 2  = 0.636). In orthopedic patients, age, the shorter time between the acute event and rehabilitation admission, shorter length of stay, and being independent with personal hygiene, dressing, and bladder were independently associated with higher total mBI at discharge (R 2  = 0.622). Our results showed that different activities in neurological (i.e. feeding, personal hygiene, bladder, and transfer) and orthopedic sample (i.e. personal hygiene, dressing, and bladder) are positively associated with better function (measured by mBI) at the discharge. Clinicians have to take into account these predictors of functionality when they plan an appropriate rehabilitation treatment.

Risk factor identification and prediction models for prolonged length of stay in hospital after acute ischemic stroke using artificial neural networks

Background

Accurate estimation of prolonged length of hospital stay after acute ischemic stroke provides crucial information on medical expenditure and subsequent disposition. This study used artificial neural networks to identify risk factors and build prediction models for a prolonged length of stay based on parameters at the time of hospitalization.

Methods

We retrieved the medical records of patients who received acute ischemic stroke diagnoses and were treated at a stroke center between January 2016 and June 2020, and a retrospective analysis of these data was performed. Prolonged length of stay was defined as a hospital stay longer than the median number of days. We applied artificial neural networks to derive prediction models using parameters associated with the length of stay that was collected at admission, and a sensitivity analysis was performed to assess the effect of each predictor. We applied 5-fold cross-validation and used the validation set to evaluate the classification performance of the artificial neural network models.

Results

Overall, 2,240 patients were enrolled in this study. The median length of hospital stay was 9 days. A total of 1,101 patients (49.2%) had a prolonged hospital stay. A prolonged length of stay is associated with worse neurological outcomes at discharge. Univariate analysis identified 14 baseline parameters associated with prolonged length of stay, and with these parameters as input, the artificial neural network model achieved training and validation areas under the curve of 0.808 and 0.788, respectively. The mean accuracy, sensitivity, specificity, positive predictive value, and negative predictive value of prediction models were 74.5, 74.9, 74.2, 75.2, and 73.9%, respectively. The key factors associated with prolonged length of stay were National Institutes of Health Stroke Scale scores at admission, atrial fibrillation, receiving thrombolytic therapy, history of hypertension, diabetes, and previous stroke.

Conclusion

The artificial neural network model achieved adequate discriminative power for predicting prolonged length of stay after acute ischemic stroke and identified crucial factors associated with a prolonged hospital stay. The proposed model can assist in clinically assessing the risk of prolonged hospitalization, informing decision-making, and developing individualized medical care plans for patients with acute ischemic stroke.

Prism Adaptation Treatment Predicts Improved Rehabilitation Responses in Stroke Patients with Spatial Neglect

Spatial neglect (SN) impedes functional recovery after stroke, leading to reduced rehabilitation gains and slowed recovery. The objective of the present study was to investigate whether integrating prism adaptation treatment (PAT) into a highly intensive rehabilitation program eliminates the negative impact of spatial neglect on functional and motor recovery. We examined clinical data of the 355 consecutive first-time stroke patients admitted to a sub-acute inpatient neurorehabilitation program that integrated PAT. The 7-item Motor Functional Independence Measure, Berg Balance Scale, and Motor Activity Log were used as main outcome measures. We found that 84 patients (23.7%) had SN, as defined by a positive score on the Catherine Bergego Scale via the Kessler Foundation Neglect Assessment Process (KF-NAP^®). Although 71 patients (85%) received PAT, the presence of SN at baseline, regardless of PAT completion, was associated with lower functional independence, higher risk of falls, and a lower functional level of the affected upper limb both at admission and at discharge. The severity of SN was associated with inferior rehabilitation outcomes. Nonetheless, patients with SN who received PAT had similar rehabilitation gains compared to patients without SN. Thus, the present study suggests that integrating PAT in an intensive rehabilitation program will result in improved responses to regular therapies in patients with SN.

Return to driving post stroke; patients' perspectives and challenges in Saudi Arabia

BackgroundReturning to driving remains one of the most important goals for stroke survivors. In Saudi Arabia, there are no structured processes to address the issue of return to driving in individuals with disabilities. There are increasing rates of strokes in the country and road traffic accidents are the highest in the region. Returning to driving among male stroke survivors in Saudi Arabia is of particular importance due to socio-economic and cultural reasons.AimsThe study aims to explore the factors involved in return to driving among stroke survivors in Saudi population.MethodsThis cross-sectional study was carried out on 100 male stroke survivors who had completed an inpatient rehabilitation program and had at least one follow-up assessment three months post-discharge. Information was collected regarding demographics, stroke characteristics, and factors related to pre and post-stroke driving. Data were analyzed using SPSS.ResultsMajority (60%) of patients were 51 years of age and above. Most commonly reported stroke impairments were weakness and spasticity with majority of participants having right-sided body involvement. Out of 94 stroke survivors who were driving prior to stroke, only 7 resumed driving. None of the stroke survivors who returned to driving reported receiving any formal driving assessment. Only one patient who reported being aware of the need of driving assessment did not resume driving after stroke.ConclusionsThere is a dire need to increase awareness and to develop a structured integrated system in Saudi Arabia to facilitate stroke survivors to return to driving.

Association of affected lower limb flexor muscle strength with swing phase duration and gait speed in elderly post-stroke patients

BACKGROUND

Although several studies have shown an association of muscle weakness with gait speed (GS), no study has explored the relationship of muscle strength with swing phase duration and GS after stroke among the elderly in Saudi Arabia.

OBJECTIVE

To examine the association of affected ankle dorsiflexor and hip flexor muscle strength with swing phase duration and GS in the elderly with different stroke chronicity.

METHODS

In this cross-sectional study, we included a total of 60 post-stroke patients aged ≥55 years who were admitted in neurorehabilitation units between May 2017 and August 2018. Linear regression was employed to examine the association of muscle strength (measured using a handheld dynamometer) with swing phase duration and GS (both measured using the computerized Zebris-Mat).

RESULTS

The chronicity of the stroke was negatively associated (p < 0.05) with swing phase duration. The ankle dorsiflexor muscle strength was significantly associated with GS (β= 0.656, p = 0.041). In contrast, hip flexor muscle strength was significantly associated with GS (β= 0.574, p < 0.0001) even after adjusting for stroke chronicity (β= 0.561, p < 0.0001).

CONCLUSIONS

Stroke chronicity was the predictor that reduced swing phase duration. The ankle dorsiflexor muscle strength was associated with GS. However, the hip flexor muscle strength was associated with GS even after adjusting for stroke chronicity.

Association between Functional Independence Measure and mortality in patients with anti-neutrophil cytoplasmic antibody-associated vasculitis: A single-center observational study

OBJECTIVES

Previous studies have identified several predictors of mortality in patients with anti-neutrophil cytoplasmic antibody-associated vasculitis (AAV). However, functional dependence as a predictor of mortality has never been reported. In this study, we investigated whether Functional Independence Measure (FIM) was associated with mortality in AAV patients.

METHODS

We analyzed 52 adults with biopsy-proven AAV in Teine Keijinkai Medical Center between January 2000 and March 2019. Adjusted Cox regression analyses were conducted to evaluate the association between three FIM-based groups and all-cause mortality. Estimates were calculated as hazard ratios with 95% confidence intervals (95% CIs).

RESULTS

During a median follow-up of 2.3 years (interquartile range, 0.7-4.6 years), death occurred in 15 patients (29%). Compared to the highest-FIM group (91-126 points), the adjusted hazard ratios for the intermediate- (55-90 points) and lowest-FIM (18-54 points) groups were 3.59 (95% CIs, 0.40-32.0) and 15.7 (95% CIs, 2.07-119) for all-cause mortality, respectively. In addition, the lower-FIM groups were associated with higher mortality (p=.0179).

CONCLUSION

This study suggested that the FIM score is a predictor of all-cause mortality in AAV patients. Future studies will have to investigate whether FIM assessment leads to better outcomes.

Clinical application of backward walking training to improve walking function, balance, and fall-risk in acute stroke: a case series

Background: With limited inpatient rehabilitation (IR) length of stays for patients post-stroke, it is critical to maximize the effectiveness of interventions to address their balance and gait speed deficits. Backward walking (BW) is an emerging training approach; however, its application to patient populations consistent with those in IR is limited. Objectives: To describe the effects of an additional BW training program to standard IR care on balance, walking ability and fall-risk in a heterogenic caseload of adults <2 weeks post-stroke with a broad range of lesion locations and physical sequelae. Methods: Eight patients with first-time stroke (5 male; average age 66.5 ± 11.7 years; average stroke onset 7.6 ± 1.6 days; 6 right hemiparesis) participated in 10-daily sessions that included 20 min of over ground BW training for each session, in addition to standard IR. Standard outcome measures were used to assess balance, walking ability and fall-risk at admission and post-intervention. Results: All eight patients demonstrated improvements in all outcomes with a clinically meaningful increase in forward walking speed, as measured by 10MWT. Four participants exceeded fall-risk cut-off scores for all balance-related outcome measures. Conclusions: In a diverse patient population early after stroke, individuals successfully participated in an additional BW training program. Despite the patients' acuity and severe impairments in walking, significant gains in balance and walking function were noted. This program may be useful in improving outcomes with patient characteristics commonly seen in IR.
