The safety of hospital stroke care

Brazilian Academy of Neurology practice guidelines for stroke rehabilitation: part I

The Guidelines for Stroke Rehabilitation are the result of a joint effort by the Scientific Department of Neurological Rehabilitation of the Brazilian Academy of Neurology aiming to guide professionals involved in the rehabilitation process to reduce functional disability and increase individual autonomy. Members of the group participated in web discussion forums with predefined themes, followed by videoconference meetings in which issues were discussed, leading to a consensus. These guidelines, divided into two parts, focus on the implications of recent clinical trials, systematic reviews, and meta-analyses in stroke rehabilitation literature. The main objective was to guide physicians, physiotherapists, speech therapists, occupational therapists, nurses, nutritionists, and other professionals involved in post-stroke care. Recommendations and levels of evidence were adapted according to the currently available literature. Part I discusses topics on rehabilitation in the acute phase, as well as prevention and management of frequent conditions and comorbidities after stroke.

Occurrence of No-Harm Incidents and Adverse Events in Hospitalized Patients with Ischemic Stroke or TIA: A Cohort Study Using Trigger Tool Methodology

Adverse events (AEs)—healthcare caused events leading to patient harm or even death—are common in healthcare. Although it is a frequently investigated topic, systematic knowledge on this phenomenon in stroke patients is limited. To determine cumulative incidence of no-harm incidents and AEs, including their severity and preventability, a cohort study using trigger tool methodology for retrospective record review was designed. The study was carried out in a stroke center at a university hospital in the German speaking part of Switzerland. Electronic records from 150 randomly selected patient admissions for transient ischemic attack (TIA) or ischemic stroke, with or without acute recanalization therapy, were used. In total, 170 events (108 AEs and 62 no-harm incidents) were identified, affecting 83 patients (55.3%; 95% CI 47 to 63.4), corresponding to an event rate of 113 events/100 admissions or 142 events/1000 patient days. The three most frequent AEs were ischemic strokes (n = 12, 7.1%), urinary tract infections (n = 11, 6.5%) and phlebitis (n = 10, 5.9%). The most frequent no-harm incidents were medication events (n = 37, 21.8%). Preventability ranged from 12.5% for allergic reactions to 100% for medication events and pressure ulcers. Most of the events found (142; 83.5%; 95% CI 76.9 to 88.6) occurred throughout the whole stroke care. The remaining 28 events (16.5%; 95% CI 11.4 to 23.1) were detected during stroke care but were related to care outside the stroke pathway. Trigger tool methodology allows detection of AEs and no-harm incidents, showing a frequent occurrence of both event types in stroke and TIA patients. Further investigations into events’ relationships with organizational systems and processes will be needed, first to achieve a better understanding of these events’ underlying mechanisms and risk factors, then to determine efforts needed to improve patient safety.

Why hospital design matters: A narrative review of built environments research relevant to stroke care

Healthcare facilities are among the most expensive buildings to construct, maintain, and operate. How building design can best support healthcare services, staff, and patients is important to consider. In this narrative review, we outline why the healthcare environment matters and describe areas of research focus and current built environment evidence that supports healthcare in general and stroke care in particular. Ward configuration, corridor design, and staff station placements can all impact care provision, staff and patient behavior. Contrary to many new ward design approaches, single-bed rooms are neither uniformly favored, nor strongly evidence-based, for people with stroke. Green spaces are important both for staff (helping to reduce stress and errors), patients and relatives, although access to, and awareness of, these and other communal spaces is often poor. Built environment research specific to stroke is limited but increasing, and we highlight emerging collaborative multistakeholder partnerships (Living Labs) contributing to this evidence base. We believe that involving engaged and informed clinicians in design and research will help shape better hospitals of the future.

Aerobic Training and Mobilization Early Post-stroke: Cautions and Considerations

Knowledge gaps exist in how we implement aerobic exercise programs during the early phases post-stroke. Therefore, the objective of this review was to provide evidence-based guidelines for pre-participation screening, mobilization, and aerobic exercise training in the hyper-acute and acute phases post-stroke. In reviewing the literature to determine safe timelines of when to initiate exercise and mobilization we considered the following factors: arterial blood pressure dysregulation, cardiac complications, blood-brain barrier disruption, hemorrhagic stroke transformation, and ischemic penumbra viability. These stroke-related impairments could intensify with inappropriate mobilization/aerobic exercise, hence we deemed the integrity of cerebral autoregulation to be an essential physiological consideration to protect the brain when progressing exercise intensity. Pre-participation screening criteria are proposed and countermeasures to protect the brain from potentially adverse circulatory effects before, during, and following mobilization/exercise sessions are introduced. For example, prolonged periods of standing and static postures before and after mobilization/aerobic exercise may elicit blood pooling and/or trigger coagulation cascades and/or cerebral hypoperfusion. Countermeasures such as avoiding prolonged standing or incorporating periodic lower limb movement to activate the venous muscle pump could counteract blood pooling after an exercise session, minimize activation of the coagulation cascade, and mitigate potential cerebral hypoperfusion. We discuss patient safety in light of the complex nature of stroke presentations (i.e., type, severity, and etiology), medical history, comorbidities such as diabetes, cardiac manifestations, medications, and complications such as anemia and dehydration. The guidelines are easily incorporated into the care model, are low-risk, and use minimal resources. These and other strategies represent opportunities for improving the safety of the activity regimen offered to those in the early phases post-stroke. The timeline for initiating and progressing exercise/mobilization parameters are contingent on recovery stages both from neurobiological and cardiovascular perspectives, which to this point have not been specifically considered in practice. This review includes tailored exercise and mobilization prescription strategies and precautions that are not resource intensive and prioritize safety in stroke recovery.

Association Between Performance on an Interdisciplinary Stroke Assessment Battery and Falls in Patients With Acute Stroke in an Inpatient Rehabilitation Facility: A Retrospective Cohort Study

OBJECTIVE

To explore the association between demographic factors and functional performance measures of patients with acute stroke in an inpatient rehabilitation facility (IRF) and falls during the IRF stay and to quantify the diagnostic accuracy of functional outcome measures in identifying fallers.

DESIGN

Retrospective cohort study.

SETTING

Inpatient rehabilitation facility.

PARTICIPANTS

Individuals with acute stroke admitted to hospital-based IRF (N=139).

INTERVENTIONS

Not applicable.

MAIN OUTCOME MEASURES

Odds ratios were used to examine the relationship between fall frequency and functional outcome measures (National Institute of Stroke Scale, neglect [Item #11], Berg Balance Scale, Stroke Rehabilitation Assessment of Movement mobility and Stroke Rehabilitation Assessment of Movement lower extremity subscales [STREAM-LE], Montreal Cognitive Assessment, Dynamic Gait Index, and Stroke Impact Scale). Receiver operator characteristic analysis with area under the curve, sensitivity, specificity, and diagnostic odds ratio were used to assess the diagnostic accuracy of each functional outcome measure to distinguish patients who fell vs those who did not fall in the IRF.

RESULTS

A total of 23 patients (16.2%) fell during the IRF hospitalization. Patients who did and did not fall did not differ in terms of age, sex, stroke type, or stroke location. Only the STREAM-LE was associated with falls (odds ratio, 0.93; 95% CI, 0.86-0.99). Area under the curve was 0.67 (95% CI, 0.51-0.82). With a positivity cutoff point of 12, sensitivity and specificity were 73.3% (95% CI, 54.6%-92.2%) and 50.0% (95% CI, 39.9%-59.2%), respectively. The diagnostic odds ratio was 3.4.

CONCLUSIONS

The STREAM-LE score at admission to IRF may identify patients with acute stroke who are more likely to fall during their stay. However, the search for measures with greater diagnostic accuracy should continue.

Falls in individuals with stroke during inpatient rehabilitation at a tertiary care hospital in Saudi Arabia

Objectives:

To determine the incidence and risk factors of falls in individuals with stroke undergoing inpatient rehabilitation.

Methods:

Retrospective analysis of all patients with stroke admitted to from January 2011 to June 2013 was carried out in Inpatient rehabilitation Unit at King Fahad Medical City, Riyadh, Kingdom of Saudi Arabia. Data collected included demographic variables, types of stroke, comorbidities, characteristics of falls, factors affecting falls and length of hospital stay. Data was descriptively analyzed. The Pearson Chi-square test was used to determine any significant relationship between the categorical variables. Binary logistic regression was used to evaluate predictors of falls during rehabilitation.

Results:

Results: Out of 146 stroke survivors, 36 patients had a fall during inpatient rehabilitation. Majority did not sustain any injury. Fall status was significantly associated with age group (p=0.048), type of stroke (p=0.005) and previous history of stroke (p=0.020). The side of stroke (p=0.011) and fall risk were statistically significantly related to fall outcomes (p=0.005). Length of hospital stay (LOS) was also associated with fall outcome (p=0.044).

Conclusion:

Age, hemorrhagic stroke, laterality of stroke and previous history of stroke were identified as risk factors associated with falls. Injured patients tend to stay longer for inpatient rehabilitation. Due to different culturual, environmental and health system variations, development of regional guidelines for fall prevention in stroke survivors can help to reduce the risk of falls.

Relationships between gait variability and ambulatory activity post stroke

BACKGROUND

Fall risk and balance confidence are related to gait variability and ambulatory activity post stroke, yet whether a relationship exists between gait variability and ambulatory activity is unknown. Knowing if gait variability measured under naturalistic conditions is related to ambulatory activity could explain more about the relationship between falls and walking activity post-stroke.

OBJECTIVES

To examine relationships between spontaneous, daily ambulatory activity and gait variability during single- and dual-task walking, in low- and high-distraction settings in adults post stroke.

METHODS

Sixteen community-dwelling adults post stroke participated in a cross-sectional study. Spatiotemporal gait parameters were recorded during single- and cognitive-motor dual-task walking in low- and high-distraction settings. Coefficient of variation was calculated for stride length and stride duration. Average walking bout duration, maximum walking bout duration, and total number of steps per day were captured using an activity monitor. Correlations between ambulatory activity measures and gait variability were examined.

RESULTS

In the high-distraction setting, single-task stride duration variability was negatively related to all three ambulatory activity measures, but the strongest relationship was a negative correlation between dual-task stride duration variability and average walking duration. In the low-distraction setting, single-task stride duration variability was negatively related to maximum walking duration. None of the other variability measures were related to ambulatory activity.

CONCLUSIONS

The finding that stride duration variability in a high-distraction environment, with or without an additional cognitive task, is related to ambulatory activity in community-dwelling stroke survivors suggests that assessments incorporating attentional demands of real-world walking may be useful additions to clinical practice.

A systematic review of falls in hospital for patients with communication disability: Highlighting an invisible population

BACKGROUND

Patients with communication disability, associated with impairments of speech, language, or voice, have a three-fold increased risk of adverse events in hospital. However, little research yet examines the causal relationship between communication disability and risk for specific adverse events in hospital.

OBJECTIVE

To examine the impact of a patient's communication disability on their falls risk in hospital.

METHODS

This systematic review examined 61 studies on falls of adult hospital patients with communication disability, and patients at high risk of communication disability, to determine whether or not communication disability increased risk for falls, and the nature of and reasons for any increased risk.

RESULTS

In total, 46 of the included studies (75%) reported on participants with communication disability, and the remainder included patients with health conditions placing them at high risk for communication disability. Two thirds of the studies examining falls risk identified communication disability as contributing to falls. Commonly, patients with communication disability were actively excluded from participation; measures of communication or cognition were not reported; and reasons for any increased risk of falls were not discussed.

CONCLUSIONS

There is some evidence that communication disability is associated with increased risk of falls. However, the role of communication disability in falls is under-researched, and reasons for the increased risk remain unclear. Practical applications: Including patients with communication disability in falls research is necessary to determine reasons for their increased risk of adverse events in hospital. Their inclusion might be helped by the involvement of speech-language pathologists in falls research teams.

A Case for Telestroke in Military Medicine: A Retrospective Analysis of Stroke Cost and Outcomes in U.S. Military Health-Care System

BACKGROUND

The development of primary stroke centers has improved outcomes for stroke patients. Telestroke networks have expanded the reach of stroke experts to underserved, geographically remote areas. This study illustrates the outcome and cost differences between neurology and primary care ischemic stroke admissions to demonstrate a need for telestroke networks within the Military Health System (MHS).

MATERIALS AND METHODS

All adult admissions with a primary diagnosis of ischemic stroke in the MHS Military Mart database from calendar years 2010 to 2015 were reviewed. Neurology, primary care, and intensive care unit (ICU) admissions were compared across primary outcomes of (1) disposition status and (2) intravenous tissue plasminogen activator administration and for secondary outcomes of (1) total cost of hospitalization and (2) length of stay (LOS).

RESULTS

A total of 3623 admissions met the study's parameters. The composition was neurology 462 (12.8%), primary care 2324 (64.1%), ICU 677 (18.7%), and other/unknown 160 (4.4%). Almost all neurology admissions (97%) were at the 3 neurology training programs, whereas a strong majority of primary care admissions (80%) were at hospitals without a neurology admitting service. Hospitals without a neurology admitting service had more discharges to rehabilitation facilities and higher rates of in-hospital mortality. LOS was also longer in primary care admissions.

CONCLUSIONS

Ischemic stroke admissions to neurology had better outcomes and decreased LOS when compared to primary care within the MHS. This demonstrates a possible gap in care. Implementation of a hub and spoke telestroke model is a potential solution.

Enhancing Patient Safety Event Reporting. A Systematic Review of System Design Features

OBJECTIVES

Electronic patient safety event reporting (e-reporting) is an effective mechanism to learn from errors and enhance patient safety. Unfortunately, the value of e-reporting system (a software or web server based platform) in patient safety research is greatly overshadowed by low quality reporting. This paper aims at revealing the current status of system features, detecting potential gaps in system design, and accordingly proposing suggestions for future design and implementation of the system.

METHODS

Three literature databases were searched for publications that contain informative descriptions of e-reporting systems. In addition, both online publicly accessible reporting forms and systems were investigated.

RESULTS

48 systems were identified and reviewed. 11 system design features and their frequencies of occurrence (Top 5: widgets (41), anonymity or confidentiality (29), hierarchy (20), validator (17), review notification (15)) were identified and summarized into a system hierarchical model.

CONCLUSIONS

The model indicated the current e-reporting systems are at an immature stage in their development, and discussed their future development direction toward efficient and effective systems to improve patient safety.

Medication Errors in Injured Patients

Trauma patients are vulnerable to medication error given multiple handoffs throughout the hospital. The purpose of this study was to assess trends in medication errors in trauma patients and the role these errors play in patient outcomes. Injured adults admitted from 2009 to 2015 to a Level I trauma center were included. Medication errors were determined based on a nurse-driven, validated, and prospectively maintained database. Multivariable logistic regression modeling was used to control for differences between groups. Among 15,635 injured adults admitted during the study period, 132 patients experienced 243 errors. Patients who experienced errors had significantly worse injury severity, lower Glasgow Coma Scale scores and higher rates of hypotension on admission, and longer lengths of stay. Before adjustment, mortality was similar between groups but morbidity was higher in the medication error group. After risk adjustment, there were no significant differences in morbidity or mortality between the groups. Medication errors in trauma patients tend to occur in significantly injured patients with long hospital stays. Appropriate adjustment when studying the impact of medical errors on patient outcomes is important.

End-of-life decisions in acute stroke patients: an observational cohort study

Background

Crucial issues of modern stroke care include best practice end-of-life-decision (EOLD)-making procedures and the provision of high-quality palliative care for dying stroke patients.

Methods

We retrospectively analyzed records of those patients who died over a 4-year period (2011–2014) on our Stroke Unit concerning EOLD, focusing on the factors that most probably guided decisions to induce limitation of life-sustaining therapy and subsequently end-of-life-care procedures thereafter.

Results

Of all patients treated at our Stroke Unit, 120 (2.71 %) died. In 101 (86.3 %), a do-not-resuscitate-order (DNRO) was made during early treatment. A decision to withdraw/withhold further life supportive therapy was made in 40 patients (34.2 %) after a mean of 5.0 days (range 0–29). Overall patient death occurred after a mean time of 7.0 days (range 1–30) and 2.6 days after therapy restrictions. Disturbance of consciousness at presentation, dysphagia on day 1 and large supratentorial stroke were possible indicators of decisions to therapeutic withdrawing/withholding. Proceedings of EOL care in these patients were heterogeneous; in most cases monitoring (95 %), medical procedures (90 %), oral medication (88 %), parenteral nutrition (98 %) and antibiotic therapy (86 %) were either not ordered or withdrawn, however IV fluids were continued in all patients.

Conclusions

A high percentage of stroke patients were rated as terminally ill and died in the course of caregiving. Disturbance of consciousness at presentation, dysphagia on day 1 and large supratentorial stroke facilitated decisions to change therapeutic goals thus initiating end-of-life-care. However, there is further need to foster research on this field in order to ameliorate outcome prognostication, to understand the dynamics of EOLD-making procedures and to educate staff to provide high-quality patient-centred palliative care in stroke medicine.

Fall-related experiences of stroke survivors: a meta-ethnography

PURPOSE

Health professionals view falls after stroke as common adverse events with both physical and psychological consequences. Stroke survivors' experiences are less well understood. The aim of this systematic review was to explore the perception of falls-risk within the stroke recovery experience from the perspective of people with stroke.

METHODS

A systematic literature search was conducted. Papers that used qualitative methods to explore the experiences of individuals with stroke around falls, falls-risk and fear of falling were included. Two reviewers independently assessed the methodological quality of papers. Meta-ethnography was conducted. Concepts from each study were translated into each other to form theories that were combined through a "lines-of-argument" synthesis.

RESULTS

Four themes emerged from the six included qualitative studies: (i) Fall circumstances, (ii) perception of fall consequences, (iii) barriers to community participation and (iv) coping strategies. The synthesis revealed that stroke survivors' perceived consequences of falls exist on a continuum. Cognitive and emotional adjustment may be required in the successful adoption of coping strategies to overcome fall-related barriers to participation.

CONCLUSIONS

Stroke survivors' fall-related experiences appear to exist within the context of activity and community participation. Further research is warranted due to the small number of substantive studies available for synthesis. Implications for Rehabilitation Health care professionals should recognize that cognitive and emotional adjustment may berequired for stroke survivors to accept strategies for overcoming falls-risk, including dependenceon carers and assistive devices. Several factors in addition to physical interventions may be needed to minimize falls-risk whileincreasing activity participation. These factors could include increasing public awareness about the effects of stroke and falls-risk,and ensuring access to psychological services for stroke survivors. Rehabilitation professionals should reflect on whether they perceive there to be an appropriatelevel of fear of falling post-stroke. They should understand that stroke survivors might not conceptualize falls-risk in this way.

Systematic review of risk prediction models for falls after stroke

BACKGROUND

Falls are a significant cause of morbidity after stroke. The aim of this review was to identify, critically appraise and summarise risk prediction models for the occurrence of falling after stroke.

METHODS

A systematic literature search was conducted in December 2014 and repeated in June 2015. Studies that used multivariable analysis to build risk prediction models for falls early after stroke were included. 2 reviewers independently assessed methodological quality. Data relating to model calibration, discrimination (C-statistic) and clinical utility (sensitivity and specificity) were extracted. A narrative review of models was conducted. PROSPERO reference: CRD42014015612.

RESULTS

The 12 included articles presented 18 risk prediction models. 7 studies predicted falls among inpatients only and 5 recorded falls in the community. Methodological quality was variable. A C-statistic was reported for 7 models and values ranged from 0.62 to 0.87. Models for use in the inpatient setting most frequently included measures of hemi-inattention, while those predicting community events included falls (or near-falls) history and balance measures most commonly. Only 2 studies reported any form of validation, and none presented a validated model with acceptable performance.

CONCLUSIONS

A number of falls-risk prediction models have been developed for use in the acute and subacute stages of stroke. Future research should focus on validating and improving existing models, with reference to the Transparent Reporting of a multivariable prediction model for Individual Prognosis Or Diagnosis (TRIPOD) guidelines to ensure quality reporting and expedite clinical implementation.

Reducing Errors in Transition from Acute Stroke Hospitalization to Inpatient Rehabilitation

OBJECTIVE

Effective stroke care does not end with acute treatment during hospitalization, but extends through rehabilitation and secondary stroke prevention. In transitions across care environments, stroke patients are vulnerable to errors in communication of diagnosis and treatment. This study aimed to demonstrate that formalized communication between the neurology team and the rehabilitation medicine team would promote secondary stroke prevention and minimize interruptions during rehabilitation.

METHODS

The intervention was a standardized verbal handoff by phone between the discharging neurology resident and the admitting rehabilitation resident regarding each patient at transfer. This retrospective cohort study compared a pre-intervention control group (September 2012 to February 2013) and a post-intervention group transferred with the handoff (September 2013 to January 2014). The outcomes measured included errors in communication of stroke severity, stroke mechanism, medications, and recommended follow-up (appointments and tests) as well as emergent brain imaging, return to the acute care facility, and readmission.

RESULTS

The pre- and post-intervention groups were similar with respect to number of patients (50 vs. 52) and demographics including gender (52 vs. 54% female), age (65.8 vs. 64.0 years), severity of illness as measured by the National Institutes of Health Stroke Scale (NIHSS) (10 vs. 6.5), and stroke type (84 vs. 77% ischemic). Implementation of the handoff decreased errors in communication of diagnosis (NIHSS 92 vs. 74%, p = 0.02; stroke mechanism 54 vs. 30%, p = 0.02). Furthermore, the handoff decreased the proportion with errors in reconciliation of critical medications (42 vs. 23%, p = 0.04). However, the intervention did not significantly reduce interruptions of the rehabilitation program, such as emergent brain imaging (8 vs. 12%, p = 0.55), or transfers back to the acute care hospital (26 vs. 21%, p = 0.56).

CONCLUSION

Standardized handoffs decreased errors in communication of diagnosis and critical medications for secondary stroke prevention.

Medication events on a tertiary neurology inpatient service

This study aimed to determine the prevalence and attributes of medication events in a tertiary inpatient neurology setting. These findings were compared with the results of a physician survey designed to assess general knowledge of medication events. We reviewed all medication events reported through an established voluntary event recording system for adult neurology inpatients at a tertiary referral center over a 2 year period. An electronic survey was sent to all neurology residents and hospital staff regarding medication events. One hundred and forty-three medication events were reported, for a rate of 8.6 events per 1000 patient-days. The medication event rate was comparable to published rates on medicine services. There was no evidence of events being more prevalent at the beginning of the academic year or on nights. One hundred and seventeen events (81.8%) reached the patient, but most (92.7%, 108/117) did not result in harm. The most common medication types involved were anticoagulants (24 events, 16.8%), anticonvulsants (17 events, 11.9%), and antibiotics (16 events, 11.2%). Nurses were involved in reporting 133 events (93%), while physicians were involved in reporting 20 events (14%). Physicians completed the survey at a rate of 60.8% (48/79). There were notable differences between physician presumptions as to medication event attributes and actual results. No trend referable to time of year or day was identified, which contrasted with physician beliefs in our survey. Nursing staff reported the majority of events.

Primary and comprehensive stroke centers: history, value and certification criteria

In the United States (US) stroke care has undergone a remarkable transformation in the past decades at several levels. At the clinical level, randomized trials have paved the way for many new stroke preventives, and recently, several new mechanical clot retrieval devices for acute stroke treatment have been cleared for use in practice by the US Federal Drug Administration. Furthermore, in the mid 1990s we witnessed regulatory approval of intravenous recombinant tissue plasminogen activator for administration in acute ischemic stroke. In the domain of organization of medical care and delivery of health services, stroke has transitioned from a disease dominated by neurologic consultation services only to one managed by vascular neurologists in geographical stroke units, stroke teams and care pathways, primary stroke center certification according to The Joint Commission, and most recently comprehensive stroke center designation under the aegis of The Joint Commission. Many organizations in the US have been involved to enhance stroke care. To name a few, the American Heart Association/American Stroke Association, Brain Attack Coalition, and National Stroke Association have been on the forefront of this movement. Additionally, governmental initiatives by the US Centers for Disease Control and Prevention and legislative initiatives such as the Paul Coverdell National Acute Stroke Registry program have paved the way to focus on stroke prevention, acute treatment and quality improvement. In this invited review, we discuss a brief history of organized stroke care in the United States, evidence to support the value of primary and comprehensive stroke centers, and the certification criteria and process to become a primary or comprehensive stroke center.

Lapses in safety in end-stage renal disease patients admitted to surgical services

Chronic dialysis patients are a vulnerable population that may be highly susceptible to medical errors, particularly when they are hospitalized. We performed a chart review of chronic hemodialysis patients admitted to surgical services at a tertiary care center in order to characterize lapses in patient safety. We conducted a retrospective chart review of admissions of patients receiving chronic hemodialysis to various surgical services at St. Michael's Hospital from January 1, 2009 to December 31, 2010. For each hospitalization, we collected data on four process of care indicators of potential safety lapses. When these lapses were identified, we sought to determine whether: (i) the lapse was detected and remedied; and (ii) the lapse resulted in an adverse event. Among the 41 patients, 96 process of care lapses were identified. Multiple lapses were detected in 83% of the cohort. Failure to order a renal diet (72%) occurred most often. There was one adverse event. Process of care lapses were detected 39% of the time, usually within 1.5 days of their occurrence. Patients receiving chronic hemodialysis admitted to surgical services experience multiple lapses in patient safety, which often remain undetected. As such, it is imperative that these patients be closely monitored in order to mitigate against potential adverse events.

Fall risk six weeks from onset of stroke and the ability of the Prediction of Falls in Rehabilitation Settings Tool and motor function to predict falls

Objective:

To investigate whether the Prediction of Falls in Rehabilitation Settings Tool (Predict FIRST) and motor function could be used to identify people at risk of falling during the first six weeks after stroke, and to compare the risk of falling according to Predict FIRST with real falls frequency.

Design:

A longitudinal, prospective study.

Patients:

Sixty-eight people newly diagnosed with stroke admitted to an acute stroke unit.

Methods:

The participants underwent an assessment of motor ability (Modified Motor Assessment Scale according to Uppsala University Hospital version 99 (M-MAS UAS-99)) and falls risk (Predict FIRST) on the first to fourth day at the acute stroke unit. Falls occurring in the acute stroke unit were recorded and falls occurring after discharge were reported by telephone follow-up. The prediction of falls was analysed with binary logistic regression.

Results:

Fourteen of the patients (21%) fell at least once during the first six weeks after stroke. The strongest significant predictor for falls was a high score on Predict FIRST (odds ratio 5.21, confidence interval (CI) 1.10–24.78) followed by M-MAS UAS-99 parts C–E (odds ratio 0.65, CI 0.44–0.95). Predict FIRST underestimated the risk of falling as the median fall risk was 9% according to Predict FIRST.

Conclusion:

Although Predict FIRST has the ability to predict falls in people with recent onset of stroke, there is some underestimation of fall risk.

An Early Mobilization Protocol Successfully Delivers More and Earlier Therapy to Acute Stroke Patients

Background. The optimal physical therapy dose in acute stroke care is unknown. The authors hypothesized that physical therapy would be significantly different between treatment arms in a trial of very early and frequent mobilization (VEM) and that immobility-related adverse events would be associated with therapy dose. Methods. This study was a single-blind, multicenter, randomized control trial. Patients admitted to a stroke unit <24 hours of stroke randomized to standard care (SC) or intervention, SC plus additional early out-of-bed therapy (VEM). Timing, amount, and type of therapy recorded throughout the trial. Adverse events were recorded to 3 months. Results. A total of 71 patients (SC n = 33, VEM n = 38) received 788 therapy sessions in the first 2 weeks of stroke. Schedule (hours to first mobilization, dose per day, frequency and session duration) and nature (percentage out-of-bed activity) of therapy differed significantly between groups ( P ≤ .001 for all components). Mobilization was earlier, happened on average 3 times per day in those receiving VEM, with the proportion of out-of-bed activity double in VEM session (median SC 42.5%, VEM 85.5%). SC consisted of 17 minutes of occupational and physiotherapy per day and was the same between groups. Number of immobility-related adverse events 3 months poststroke was not associated with therapy dose or frequency. Conclusions. The authors detailed usual care and intervention therapy provided to patients from admission to 14 days after stroke. The therapy schedule was markedly different in the intervention arm, but whether this schedule reduces complications or improves outcome is unknown.

Bone mineral density in adults disabled through acquired neurological conditions: a review

This article is a review of the changes in bone mineral density (BMD), which occur in a number of acquired neurological conditions resulting in disability. For each of spinal cord injury, stroke, multiple sclerosis, Parkinson's disease, and traumatic brain injury, the following aspects are discussed, where information is available: prevalence of low BMD according to World Health Organization diagnostic categories and recommended diagnostic method, prevalence based on other diagnostic tools, comparison of BMD with a control population, rate of decline of BMD following onset of the neurological condition, factors influencing decline; mechanism of bone loss, and fracture rates. The common risk factors of immobilization and vitamin D deficiency would appear to cross all disability groups, with the most rapid phase of bone loss occurring in the acute and subacute phases of each condition.

On the integration and standardization of medication error data: taxonomies, terminologies, causes and contributing factors

OBJECTIVE

A reliable database on the causes and contributing factors of medication errors can inform strategies for their prevention. To form a single database from multiple databases requires a process of integration that both maximizes the utility of the new data and minimizes the loss of information. Unfortunately, the terminologies used by different studies and databases may limit integration; therefore, terminologies must be standardized prior to integration.

METHODS

The National Coordinating Council for Medication Error Reporting and Prevention (NCC MERP) Taxonomy of Medication Errors was applied to standardize the different terminologies in 11 studies that reported the causes or contributing factors of medication errors.

RESULTS

After standardization, 57% of the reported causes and contributing factors were integrated to form a database while 43% were not integrated because the terminologies could not be standardized or were not similar to the taxonomy.

CONCLUSIONS

This study highlights the challenges to standardizing and integrating databases and the importance of adopting and applying a standardized terminology to record medical errors.

[Falls: incidence and risk factors after stroke. A systematic literature review]

Falls are common after stroke. This article presents a literature review of the incidence and risk factors of falls and the consequences for professionals working with stroke patients. It is important to consider the specific problems after stroke. Depression and cognitive impairments were found to be risk factors for fall incidents after stroke. In the relevant literature many different risk factors and circumstances are described. When patients move from bed to chair, walk to the bathroom and the first few days after the patient is discharged to another setting, - all these circumstances showed high percentages of falling. A fall during hospital stay is a significant risk factor for future fall incidents. A reliable index to measure the fall risk is not (yet) available. But scores on the Barthel Index and the Timed-Up-and-Go test can be used as fall risk indicators. Fear of falling is an important complication after a fall and therefore it is recommended prior to discharge to inquire about the patient's self efficacy in maintaining balance. Few intervention studies use the number of falls as an outcome measure. Exercising balance following a mass training protocol seems to diminish the risk of falling.

Can outcome prediction data change patient outcomes and organizational outcomes?

PURPOSE OF REVIEW

Intensive care medicine consumes a high share of healthcare costs, and there is growing pressure to use the scarce resources efficiently. Accordingly, organizational issues and quality management have become an important focus of interest in recent years. Here, we will review current concepts of how outcome data can be used to identify areas requiring action.

RECENT FINDINGS

Using recently established models of outcome assessment, wide variability between individual ICUs is found, both with respect to outcome and resource use. Such variability implies that there are large differences in patient care processes not only within the ICU but also in pre-ICU and post-ICU care. Indeed, measures to improve the patient process in the ICU (including care of the critically ill, patient safety, and management of the ICU) have been presented in a number of recently published papers.

SUMMARY

Outcome assessment models provide an important framework for benchmarking. They may help the individual ICU to spot appropriate fields of action, plan and initiate quality improvement projects, and monitor the consequences of such activity.
