Development and implementation of clinical pathways for stroke on a multihospital basis

Protocol management of severe traumatic brain injury in intensive care units: a systematic review

To examine clinical trials and observational studies that compared use of management protocols (MPs) versus usual care for adult intensive care unit (ICU) patients with acute severe traumatic brain injury (TBI) on 6-month neurologic outcome (Glasgow Outcome Scale, GOS) and mortality, major electronic databases were searched from 1950 to April 18, 2011. Abstracts from major international meetings were searched to identify gray literature. A total of 6,151 articles were identified; 488 were reviewed in full and 13 studies were included. Data on patient and MP characteristics, outcomes and methodological quality were extracted. All 13 included studies were observational. A random effects model showed that use of MPs was associated with a favorable neurologic outcome (GOS 4 or 5) at 6 months (odds ratio [OR] and 95 % confidence interval [CI] 3.84 (2.47-5.96)) but not 12 months (OR, 95 % CI 0.87 (0.56-1.36)). Use of MPs was associated with reduced mortality at hospital discharge and 6 months (OR and 95 % CI 0.72 (0.45-1.14) and 0.33 (0.13-0.82) respectively), but not 12 months (OR, 95 % CI 0.79 (0.5-1.24)). Sources of heterogeneity included variation in study design, methodological quality, MP design, MP neurophysiologic endpoints, and type of ICU. MPs for severe TBI were associated with reductions in death and improved neurologic outcome. Although no definitive conclusions about the efficacy of MPs for severe TBI can be drawn from our study, these results should encourage the conduct of randomized controlled trials to more rigorously examine the efficacy of MPs for severe TBI.

Evaluating service delivery for speech and swallowing problems following paediatric brain injury: an international survey

RATIONALE, AIMS AND OBJECTIVES

Little is documented about contemporary management of speech and swallowing disorders associated with paediatric acquired brain injury (ABI). It is therefore challenging for clinicians in this field to benchmark their clinical management against current evidence or practices undertaken in other centres. To address this issue, we aimed to provide much-needed baseline data on speech and language pathology management of speech and swallowing disorders associated with childhood ABI. Key objectives were to: (i) determine whether clinicians use formalized referral criteria, clinical guidelines, protocols or care pathways; and (ii) to document the specific assessment and treatment approaches used.

METHODS

Speech and language pathology managers and clinicians at 31 major paediatric rehabilitation centres across Australia, New Zealand, the UK and Ireland were invited to participate in an online survey.

RESULTS

Fifty-one speech and language pathologists responded representing 26 centres (84% response rate). Routine referrals of ABI patients to speech and language pathology occurred relatively infrequently in these centres (12%). Centres utilized assessment protocols (23%) and guidelines (35%) more frequently than treatment guidelines (8%). Multidisciplinary care pathways were applied by 31%. Most centres used adult-based motor speech assessments and informal ('in-house developed') swallowing assessment tools.

CONCLUSIONS

The limited use of referral criteria, protocols, care pathways and guidelines invites the possibility of unequal care, and less than optimal outcomes. Reliance on adult-based or in-house assessments is inappropriate, yet frequently a necessity due to an absence of paediatric-specific tools in this field. Further research is required in parallel with the formation of consensus groups to support the development of: (i) paediatric-specific assessment tools and management approaches; and (ii) clinical protocols and guidelines.

Care pathways for acute stroke care and stroke rehabilitation: from theory to evidence

Care pathways aim to promote evidence- and guideline-based care, improve the organisation and efficiency of care, and reduce cost. In the past decade, care pathways have been increasingly implemented as a tool in acute stroke care and stroke rehabilitation. In the most recent Cochrane systematic review, which included three randomised and 12 non-randomised studies, patient management with stroke care pathways was found to have no significant benefit on functional outcome, and patient satisfaction and quality of life might actually be worse. On the other hand, it was associated with a higher proportion of patients receiving investigations and a lower risk of developing certain complications such as infections and readmissions. Overall, the evidence supports the use of care pathways in acute stroke but not stroke rehabilitation. Future developments, including electronic care pathways, patient pathways, and pre-hospital care pathways for hyperacute stroke, will be discussed.

Variation in hospital length of stay: do physicians adapt their length of stay decisions to what is usual in the hospital where they work?

OBJECTIVE

To test the hypothesis that physicians who work in different hospitals adapt their length of stay decisions to what is usual in the hospital under consideration.

DATA SOURCES

Secondary data were used, originating from the Statewide Planning and Research Cooperative System (SPARCS). SPARCS is a major management tool for assisting hospitals, agencies, and health care organizations with decision making in relation to financial planning and monitoring of inpatient and ambulatory surgery services and costs in New York state.

STUDY DESIGN

Data on length of stay for surgical interventions and medical conditions (a total of seven diagnosis-related groups [DRGs]) were studied, to find out whether there is more variation between than within hospitals. Data (1999, 2000, and 2001) from all hospitals in New York state were used. The study examined physicians practicing in one hospital and physicians practicing in more than one hospital, to determine whether average length of stay differs according to the hospital of practice. Multilevel models were used to determine variation between and within hospitals. A t-test was used to test whether length of stay for patients of each multihospital physician differed from the average length of stay in each of the two hospitals.

PRINCIPAL FINDINGS

There is significantly (p<.05) more variation between than within hospitals in most of the study populations. Physicians working in two hospitals had patient lengths of stay comparable with the usual practice in the hospital where the procedure was performed. The proportion of physicians working in one hospital did not have a consistent effect for all DRGs on the variation within hospitals.

CONCLUSION

Physicians adapt to their colleagues or to the managerial demands of the particular hospital in which they work. The hospital and broader work environment should be taken into account when developing effective interventions to reduce variation in medical practice.

In-hospital care pathways for stroke

BACKGROUND

Stroke care pathways have the potential to promote organised and efficient patient care that is based on best evidence and guidelines, but evidence to support their use is unclear.

OBJECTIVES

We aimed to assess the effects of care pathways, compared with standard medical care, among patients with acute stroke who had been admitted to hospital.

SEARCH STRATEGY

We searched the Cochrane Stroke Group Trials Register (last searched in June 2003), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 2, 2003), MEDLINE (1975 to June 2003), EMBASE (1980 to June 2003), CINAHL (1982 to June 2003), ISI Proceedings: Science & Technology (1990 to November 2003), and HealthSTAR (1994 to May 2001). We also handsearched the Journal of Integrated Care Pathways (2001 to 2003), formerly Journal of Managed Care (1997 to 1998) and Journal of Integrated Care (1998 to 2001). Reference lists of articles were searched.

SELECTION CRITERIA

We considered randomised controlled trials and non-randomised studies that compared care pathway care with standard medical care.

DATA COLLECTION AND ANALYSIS

One reviewer selected studies for inclusion and the other independently checked the decisions. Two reviewers independently assessed the methodological quality of the studies. One reviewer extracted the data and the other checked the extracted data.

MAIN RESULTS

Three randomised controlled trials (340 patients) and 12 non-randomised studies (4081 patients) were included. There was significant statistical heterogeneity in the analysis of many of the outcomes. We found no significant difference between care pathway and control groups in terms of death or discharge destination. Patients managed with a care pathway were: (a) more dependent at discharge (P = 0.04); (b) less likely to suffer a urinary tract infection (Odds Ratio (OR) 0.51, 95% Confidence Interval (CI) 0.34 to 0.79); (c) less likely to be readmitted (OR 0.11, 95% CI 0.03 to 0.39); and (d) more likely to have neuroimaging (OR 2.42, 95% CI 1.12 to 5.25). Evidence from randomised trials suggested that patient satisfaction and quality of life were significantly lower in the care pathway group (P = 0.02 and P < 0.005 respectively).

REVIEWERS' CONCLUSIONS

Use of stroke care pathways may be associated with positive and negative effects. Since most of the results have been derived from non-randomised studies, they are likely to be influenced by potential biases and confounding factors. There is currently insufficient supporting evidence to justify the routine implementation of care pathways for acute stroke management or stroke rehabilitation.

Effect of an Outcomes-Managed Approach to Care of Neuroscience Patients by Acute Care Nurse Practitioners

• Objective To improve clinical and financial outcomes for neuroscience patients by using an “outcomes-managed” model of care delivery and 2 acute care nurse practitioners as outcomes managers.

• Methods Baseline data from the year before implementation of the care model were compared with data from the first 6 months of implementation. A random list of 122 adult patients admitted to the neuroscience intensive care unit or the acute care neurosurgery unit of a university teaching hospital between January and December 1998 was generated to provide the baseline data. The prospective sample included 402 patients admitted to either unit during the first 6 months of the project (January through June 1999). The acute care nurse practitioners used an evidence-based multidisciplinary plan of care to manage all patients.

• ResultsNo differences were found in age, sex, or ethnicity between groups. Patients managed by acute care nurse practitioners had significantly shorter overall length of stay (P = .03), shorter mean length of stay in the intensive care unit (P&lt;.001), lower rates of urinary tract infection and skin breakdown (P&lt;.05), and shorter time to discontinuation of the Foley catheter and mobilization (P &lt; .05). The outcomes-managed group was hospitalized 2306 fewer days than the baseline group, at a total cost savings of $2 467 328.

• Conclusions Clinical and financial outcomes are improved significantly by identifying patients at risk, monitoring for complications, and having acute care nurse practitioners manage the patients.

In-hospital care pathways for stroke

BACKGROUND

Care within a stroke unit reduces death or dependency after stroke. However, studies have found significant variations in clinical practice, access to stroke unit care, organisation of patient care, and clinical outcome. Stroke care pathways have been introduced as a method to promote organised and efficient patient care that is based on best evidence and guidelines.

OBJECTIVES

We aimed to assess the effects of care pathways, as compared to standard medical care, among patients with acute stroke who had been admitted to hospital.

SEARCH STRATEGY

We searched the Cochrane Stroke Group Specialised Trials Register (last searched in May 2001), the Cochrane Controlled Trials Register (Issue 4, 2000), MEDLINE (1975-2000), EMBASE (1980-2000), CINAHL (1982-2000), the Index to Scientific and Technical Proceedings (ISTP, May 2001), and HealthSTAR (May 2001). We also handsearched the Journal of Managed Care (1997 to 1998), which was later renamed the Journal of Integrated Care (1998 to 2001). Reference lists of articles were searched.

SELECTION CRITERIA

We considered randomised controlled trials and non-randomised studies (quasi-randomised trials, comparative studies, controlled and uncontrolled before and after studies, and interrupted time series) that compared care pathway care with standard medical care.

DATA COLLECTION AND ANALYSIS

One reviewer selected studies for inclusion and the other independently checked the decisions. Two reviewers independently assessed the methodological quality of the studies. One reviewer extracted the data and the other checked the extracted data. Data from randomised and non-randomised studies were analysed separately. We found significant statistical heterogeneity in the analysis of two outcomes (computed tomography brain scanning and duration of stay).

MAIN RESULTS

There were three randomised controlled trials (total of 340 patients) and seven non-randomised studies (total of 1673 patients) that compared care pathway care with standard medical care. We found no difference between care pathway and control groups in terms of death, dependency, or discharge destination. Evidence from mainly non-randomised studies suggests that patients managed using a care pathway may be: a) less likely to suffer a urinary tract infection (OR 0.38, CI 0.18 to 0.79), b) less likely to be readmitted (OR 0.11, CI 0.03 to 0.39), and c) more likely to have a computed tomography brain scan (OR 3.66, CI 1.45 to 9.27) or carotid duplex study (OR 2.45, CI 1.3 to 4.61). Evidence from randomised trials suggests that patient satisfaction and quality of life may be significantly lower in the care pathway group (P=0.02 and P<0.005 respectively).

REVIEWER'S CONCLUSIONS

The use of care pathways to manage stroke patients in hospital may be associated with both positive and negative effects on the process of care and clinical outcomes. Since most of the results have been derived from non-randomised studies, they are likely to be influenced by potential biases and confounding factors. There is currently insufficient supporting evidence to justify routine implementation of care pathways for acute stroke management or stroke rehabilitation.

Hospital care pathways for patients with schizophrenia

Greater emphasis is being placed on reducing clinical variation in managing patient groups in the reformed National Health Service (NHS) in the United Kingdom (UK). The use of a care pathway to enable greater control over the process and quality of care will be explored for patients suffering from schizophrenia. The paper addresses three main factors for the development of care pathways for people suffering from schizophrenia: predictability of the illness; nature of standardized care; and role autonomy. It is argued that the diagnosis of schizophrenia does not lend itself easily to predicting care and treatment within a care pathway framework. However, a care pathway may bring other benefits, such as standardized care and a greater control over the delivery of care. Development and implementation of hospital care pathways require extensiv research. Qualitative research directions are advocated due to the possib difficulties of conducting an experimental study.

Care pathways: an evaluation of their effectiveness

This paper reports on a quasi-experimental case study of two care pathways--a midwifery-led maternity pathway and a breast disease pathway developed within one British National Health Service Trust. Of the aspects evaluated, those reported here are: a comparison of clinical care delivered before (the control group) and after the introduction of the two pathways; a comparison of patient satisfaction levels before (the control group) and after the introduction of the two pathways; and views of staff involved in the development and operation of the two pathways. The results are mixed. In the breast disease pathway five of 12 clinical indicators showed change, but only two of these showed statistically significant changes; three were considered of clinical significance but could not be tested statistically. In the maternity pathway, after allowing for the effect of gravid status, five of 10 indicators showed changes between the pre-pathway and pathway users and of these four showed statistically significant changes. Patient satisfaction levels showed little overall change--only 15% of the questions for breast disease and 9% for maternity showed any statistically significant change. However, both surveys indicated precise areas where a change resulting from the introduction of the pathway could be linked to an increase in satisfaction. The clinical staff interviewed highlighted many positive features of the tool (26/40 comments). The most frequently cited favourable comment was its ability to make staff focus on the clinical care they were providing and how this could be improved. It also highlighted some areas for concern, in particular the introduction of pathway documentation.

The implementation of clinical paths for six common urological procedures, and an analysis of variances

OBJECTIVE

To evaluate the outcomes of treatment after implementing clinical paths for six common urological procedures, and analyse the variances from these paths.

PATIENTS AND METHODS

The study comprised 1006 consecutive patients treated according to the recommendations of the clinical path for six common urological procedures; the results of treatment were compared with those from 1006 patients treated by the same physicians before implementing the clinical paths. Total admission charges were divided into five categories, i.e. operation and anaesthesia, laboratory, radiology, pharmacy and other. The differences in these five categories before and after implementation were determined; the variance data were also tracked and analysed. Five quality indicators were monitored during implementation and compared with the data before implementation.

RESULTS

The mean length of hospital stay (LOS) and admission charges were significantly lower (P=0.03 and P<0.01) after implementation. The charges for laboratory, radiology, pharmacy and other were significantly decreased after the use of clinical paths. The common variations from the clinical paths were patient-related variance (33%) and discharge variance (26%). Variances affecting the LOS only or the admission charge only were more common than those affecting neither the LOS nor admission charges (both P<0.01), or both (both P<0.01). After implementation, the results of the five quality indicators were significantly improved and the number of patients with surgical complications was significantly reduced (P<0. 01), but the mortality and readmission rate did not increase.

CONCLUSIONS

The implementation of clinical paths for six common urological procedures decreased the LOS, admission charges and surgical complications, and improved the quality of care. During implementation, variances can affect the LOS and/or admission charges.
