Improving performance through knowledge translation in the Veterans Health Administration

The Veterans Health Administration (VA) provides a case study for linking performance measurement, information technology, and aligned research efforts to facilitate quality improvement in a large, complex health system. Dialogue between clinical researchers and VA leaders occurs through structured activities (e.g., the Quality Enhancement Research Initiative); engagement with formal policymaking bodies (e.g., development of clinical guidelines and performance measures); and informally through local, regional, and national work groups responsible for implementing evidence-based clinical initiatives. Important lessons for knowledge translation from the VA experience include the following: research needs to generate clinical evidence relevant to the needs of patients served by the health system; researchers need to systematically study the process of evidence implementation itself to increase the capability of the health system to improve performance; although print and Web-based dissemination structures are important, direct accessibility of researchers to policymakers and clinical leaders through formal and informal mechanisms is key; and both top-down and bottom-up activities are needed to integrate evidence-based practice across a large health system. As VA care moves from hospital and clinic into community-based settings and faces a new veteran population with different needs and expectations, knowledge-translation activities must develop new forms of evidence and more direct interaction with veterans and their caregivers.     

Formal support of stroke survivors and their informal carers in the community: a cohort study

This cohort study, aims to explore formal care provision to stroke survivors and their informal carers in the community in the UK. An initial cohort of 105 cohabitant carers of first-time stroke patients was recruited while the stroke patient was in hospital. Structured face-to-face interviews were carried out with carers prior to discharge of the stroke patient home, at 6 weeks after discharge, and 15 months after stroke. Questionnaires included measures of psychological health (CIS-R), physical health (self-rated health), social well-being (relationship quality and Sarason's social support questionnaire), handicap of the stroke survivor (Oxford Handicap Scale) and formal community support (amount of formal support and carer satisfaction). Multiple services were involved with most survivor-carer pairs (mean 5.4; range 2-9; SD = 1.7), and 74% of carers were satisfied with formal support provided. Number of services decreased with time (5.5 versus 4.1, t = 4.201, d.f. = 52, P < 0.001, 95% confidence interval: 0.71-2.01) but not time allocated. Using stepwise linear regression, service provision early after discharge was predicted by: level of handicap, recruitment centre, carer self-rated health, number of informal supporters and other care commitments. Satisfaction was predicted by quality of informal support and activity restriction. Fifteen months after stroke, predictors of formal care were: level of handicap, quality of informal support and previous caring experience. Predictors of satisfaction were: quality of the relationship between the stroke survivor and carer, age and mood. Quality of services was good, but carers lacked information, had insufficient help and were not consulted enough. Carer distress is common, yet not currently a factor influencing support provision. Formal care provided adapts with time reflecting the importance of quality of support from friends and family rather than quantity of informal supporters. These factors should be taken into consideration when planning and providing formal support for stroke survivors and their carers.     

Formal and informal inter‐organizational coordination: How nurses adapt in complex pathways

With the coordination of health care services becoming increasingly complex, the challenges of fragmentation cannot be solved by administrative restructuring alone. Attention must also be given to the coordination practices of professional groups, and, in this respect, the nursing profession is a particularly interesting case. Based on a qualitative case study of Danish nurses in hospital, municipality, and general practice, this article addresses the following question: How does the nursing profession practice formal and informal inter‐organisational coordination in complex pathways, and what is the interplay between the 2 types of coordination? The findings contribute to our knowledge of coordination at the operative level of health care by identifying specific informal practices in inter‐organisational coordination and by showing how informal coordination is activated to support formal coordination in a concurrent organisational and professional ambition of integration. The nurses studied here proved very loyal to formal inter‐organisational coordination mechanisms, prioritising them as first choices of action. When formal procedures were found insufficient, however, the nurses temporarily switched to informal coordination. This was triggered by random encounters with fragmentation, a strong professional engagement in making things work in the interest of the patient, and a constant striving to be on top of things. Informal inter‐organisational coordination is broken down into supplementary and by‐passing practices, and 4 specific by‐passing practices are identified. The discussion offers insight into how a lack of agency related to formal inter‐organisational coordination can be related to negotiated settlements, and informal coordination is considered in terms of “rule bending” within complex systems.     

Use of child development assessment in early childhood education: early childhood practitioner and student attitudes toward formal and informal testing

Twenty early childhood practitioners (ECPs) and final‐year Bachelor of Early Childhood Studies students completed a questionnaire about their use (or planned use) of formal and informal child development assessment instruments, their choice of specific instruments, and factors influencing decisions to conduct child development assessments within their early childhood programmes. While most ECPs and all students indicated use (or planned use) of informal assessment, 70% of students and only 10% of ECPs indicated use of formal assessment. Whereas ECPs identified ‘ease of use’ as most important, ‘accuracy of the instrument’ was most important to students. In deciding to use any assessment, students ranked ‘identifies children at risk’ as most important, compared with ECPs who ranked ‘provides a good picture of children's development’ as most important. Results are discussed in terms of their implications for the early childhood field and for pre‐service training in child development assessment.     

Formal and informal care for community‐dwelling frail elderly people over time: A comparison of integrated and usual care in the Netherlands

While integration has become a central tenet of community‐based care for frail elderly people, little is known about its impact on formal and informal care and their dynamics over time. The aim of this study was therefore to examine how an integrated care intervention for community‐dwelling frail elderly people affects the amount and type of formal and informal care over 12 months as compared to usual care. A quasi‐experimental design with a control group was used. Data regarding formal and informal care were collected from frail elderly patients (n = 207) and informal caregivers (n = 74) with pre/post‐questionnaires. Within‐ and between‐group comparisons and multiple linear regression analyses were performed. The results showed marginal changes over time in the amount of formal and informal care in both integrated care and usual care. However, different associations between changes in formal and informal care were found in integrated and usual care. Most notably, informal caregivers provided more instrumental assistance over time if formal caregivers provided less personal care (and vice versa) in integrated care but not in usual care. These results suggest that integrated care does not necessarily change the contribution of formal or informal care, but changes the interaction between formal (personal care) and informal (instrumental) activities. Implications and recommendations for research and practice are discussed. Trial registration: Current Controlled Trials ISRNT05748494.     

Use of quality information in decision‐making about health and social care services – a systematic review

User choice and personalisation have been at the centre of health and social care policies in many countries. Exercising choice can be especially challenging for people with long‐term conditions (LTC) or disabilities. Information about the quality, cost and availability of services is central to user choice. This study used systematic review methods to synthesise evidence in three main areas: (i) how people with LTC or disabilities and their family carers find and access information about the quality of services; (ii) how quality information is used in decision‐making; and (iii) what type of quality information is most useful. Quality information was defined broadly and could include formal quality reports (e.g. inspection reports, report cards, etc.), information about the characteristics of a service or provider (e.g. number and qualifications of staff, facilities, etc.) and informal reports about quality (e.g. personal experience, etc.). Literature searches were carried out using electronic databases in January 2012. Thirteen papers reporting findings from empirical studies published between 2001 and 2012 were included in the review. The majority of papers (n = 9) had a qualitative design. The analysis highlighted the use of multiple sources of information in decision‐making about services and in particular the importance of informal sources and extended social networks in accessing information. There is limited awareness and use of ‘official’ and online information sources. Service users or family carers place greater emphasis on general information and structural indicators. Clinical or quality‐of‐life outcomes are often difficult to interpret and apply. Trust emerged a key issue in relation to quality information. Experiential and subjective information is highly valued and trusted. Various barriers to the effective use of quality information in making choices about services are identified. Implications for policy and future research are discussed.     

Does informal care impact utilisation of home‐based formal care services among end‐of‐life patients? A decade of evidence from Ontario,Canada

Understanding how informal care impacts formal care utilisation for home‐based end‐of‐life patients is an important policy‐ and practice‐relevant question. This paper aims to assess the relationship between informal and formal home care among home‐based end‐of‐life patients and how this relationship has changed over the last decade and over the end‐of‐life trajectory. We focus on informal care provided by family members or friends, and three types of home‐based formal care services: care by personal support workers, physician visits, and nurse visits. Using survey data collected in a home‐based end‐of‐life care programme in Ontario, Canada from 2005 to 2016, we build a two‐part utilisation model analysing both the propensity to use each type of formal care and the amount of formal care received by patients. The results suggest that informal care is a substitute for care by personal support workers, but a complement to physician visits and nurse visits. In the case of nurse visits, an increased complementary effect is observed in more recent years. For home‐based physician and nurse visits, the complementary effect grows with patient's proximity to death. These results highlight the complexity of the relationship between informal and formal care among home‐based end‐of‐life patients. Decision‐makers need to take into account the relationship between informal care and different types of formal services when introducing future policies.     

The role of risk and benefit perception in informed consent for surgery.

BACKGROUND: Informed consent relies on patients' ability to understand risk information. Evidence suggests that people may extract the gist of any risk information to make medical decisions. Existing evidence also suggests that there is an inverse relationship between the perception of risk and the perception of benefit. METHOD: Seventy-one patients on the waiting list for carotid endarterectomy (CEA) were surveyed regarding their understanding and recall of the risk and benefit to health of undergoing CEA. Patients were surveyed 1 month after their initial consultation, and a subgroup was surveyed again on the day before their operation. RESULTS: Patients' estimates of their baseline risk of stroke without surgery were significantly different from what they had been told by the surgeon. Patients' estimates of stroke risk due to surgery ranged from 0% to 65% (actual local risk 2%). Patients also had unreasonable expectations about the benefit of the operation for their health. Estimates of stroke risk correlated positively with the degree of expected benefit from the operation (r = 0.29, P = 0.05). When resurveyed the day before the operation, patients' perceptions of both risk and benefit had increased significantly. The risk perception data from some patients appeared to contradict some of the predictions of the fuzzy-trace theory. CONCLUSIONS: Most patients failed to understand the risks and benefits associated with CEA. Some patients' estimates of stroke risk were actually greater than the perceived potential benefit of surgery in terms of risk reduction. The data also suggested a positive correlation between the degree of perceived benefit and the degree of perceived risk.     

Prevention of cardiovascular complications after a stroke or TIA: hypotensive and hypocholesterolemic therapy

In patients who have recently had a TIA or stroke, the risk of new serious cardiovascular disease is decreased by the pharmacological reduction of the serum cholesterol level and blood pressure; this has been convincingly demonstrated by randomised clinical trials. There is sufficient evidence that cholesterol-lowering treatment is effective in patients with a TIA or cerebral infarction who have a total cholesterol > or = 3.5 mmol/l. The results from a trial in patients with only a TIA or a minor stroke will have to answer the question whether cholesterol-lowering treatment will be effective in patients > 80 years, and whether higher dosages of simvastatin will be more effective in these patients. Antihypertensive therapy is effective in preventing recurrent stroke and myocardial infarction in patients with a recent stroke or TIA. It is obvious that the treatment should be started with a diuretic and that a second agent should be added if necessary. On epidemiological grounds, vigorous treatment is also justified in patients with a normal or mildly elevated blood pressure; caution and a custom-tailored approach are essential, however, in each individual patient.     

Heavy cannabis users at elevated risk of stroke: evidence from a general population survey

Objective: Case reports and hospital‐based case–control studies suggest that cannabis use may increase the risk of stroke. We examined the risk of non‐fatal stroke or transient ischemic attack (TIA) among cannabis users in the general community. Method: A general population survey of Australians aged 20–24 years (n=2,383), 40–44 years (n=2,525) and 60–64 years (n=2,547) was used to determine the odds of lifetime stroke or TIA among participants who had smoked cannabis in the past year while adjusting for other stroke risk factors. Results: There were 153 stroke/TIA cases (2.1%). After adjusting for age cohort, past year cannabis users (n=1,043) had 3.3 times the rate of stroke/TIA (95% CI 1.8–6.3, p<0.001). The incidence rate ratio (IRR) reduced to 2.3 after adjustment for covariates related to stroke, including tobacco smoking (95% CI 1.1–4.5). Elevated stroke/TIA was specific to participants who used cannabis weekly or more often (IRR 4.7, 95% CI 2.1–10.7) with no elevation among participants who used cannabis less often. Conclusions: Heavy cannabis users in the general community have a higher rate of non‐fatal stroke or transient ischemic attack than non‐cannabis users.     

Factors influencing informal care-giving

BACKGROUND: As downsizing of institutional care continues, patients discharged are likely to have more severe mental illnesses, and to have experienced longer tenures within institutions than patients who have been discharged in the past. As greater numbers of patients are removed from mental hospitals, the objective burden experienced by informal care-givers may increase, particularly if formal care levels are inadequate. AIMS OF THE STUDY: This paper documents who assumes informal care-giver roles, and the form such care-giving takes for patients discharged from a state hospital. Specifically, this paper identifies (i) what factors affect a person's decision to assume a care-giver role, including the participation of other network members in care-giving, (ii) what factors influence whether care-giving is provided in time or in direct purchase of care and (iii) how the patient's treatment location affects the decision of the network member to assume any care-giving role. DATA AND ANALYTICAL METHODS: Data for this paper are taken from a longitudinal study of the closure of a state mental hospital in central Indiana. Seventy-seven patients were asked to identify their community networks. Ninety-eight network members were surveyed about the informal care, both in time or through direct expenditures, they provided to these patients one year after discharge. Care-giving relationships were estimated using a multivariate probit model. Such a model estimates the extent to which the decision to provide care in either form depends on the care-giving activities assumed by other network members associated with a given patient, as well as the characteristics of individual patients and network members. RESULTS: Forty-one per cent of network members provided some level of informal care, with 13.3% providing some care in time, and 35.7% providing some care through direct expenditures. A positive relationship was found between participation in informal care-giving and the perception by the network member that patient needs were not being met by professionals. The decision to provide informal care was also found to be sensitive to the level of informal and formal care received by the patient. Care-giving in expense was found to be positively related to the care-giving decisions of other informal care-givers, but care-giving in time was not. Network members were more likely to provide care in time for patients who had been recently discharged to the community than for patients who remained in institutional settings. CONCLUSIONS: These results suggest the transfer of persons with severe mental illnesses from state hospitals to the community may shift the care burden between formal and informal providers. If this is the case, discharge criteria should include such factors as the community resources available to the patient. IMPLICATIONS FOR HEALTH CARE PROVISION AND USE: The responsiveness of network members to perceived unmet need bespeaks the importance of informal care when the continuity of formal care cannot be assured. Findings also suggest there may be some substitution of formal and informal care when patients are discharged from institutions. Further analysis is required to determine whether network members' perceptions of unmet need are accurate, and means by which network members can be made better attuned to unmet needs actually experienced by patients.     

Public financial support receipt and non-medical resource utilization in Alzheimer's disease results from the PLASA study

A major health policy objective is to encourage and sustain informal caregiving networks for people with Alzheimer's disease (AD). This goal can be reached by providing financial assistance to patients facing difficulties in the accomplishment of activities of daily living, in order to encourage utilization of professional service and therefore alleviate informal caregiver burden. The main issue is to understand if and how financial assistance is correlated with the distribution between informal and professional care. We used a cross-sectional sample of 1131 French elderly patients (≥65) with mild to moderate AD. Informal and professional service resource use was measured in hours per month using a validated instrument, the Resource Use in Dementia questionnaire. Our results confirmed the utter dominance of informal care, which represented more than 80% of total care even among patients receiving public financial support. However financial support receipt was associated with differences in care utilization: higher use of total non-medical care (formal and informal) and lower proportion of informal care in total non-medical care. Our results suggested the presence of a threshold effect that would influence non-medical care demand decisions. Even if on average the use of informal care in total was 13.3% lower among patients receiving public financial support, informal care use represented more than 80% of total non-medical care use. Providing robust evidence of these associations is crucial to further identify the right dosage between professional service demand and informal care utilization that could be associated with a lower burden and therefore a lower probability of institutionalization.     

How do supply‐side factors influence informal payments for healthcare? The case of HIV patients in Cameroon

Direct out‐of‐pocket payments for healthcare continue to be a major source of health financing in low‐income and middle‐income countries. Some of these direct payments take the form of informal charges paid by patients to access the needed healthcare services. Remarkably, however, little is known about the extent to which these payments are exercised and their determinants in the context of Sub‐Saharan Africa. This study attempts therefore to shed light on the role of supply‐side factors in the occurrence of informal payments while accounting for the demand‐side factors. The study relies on data taken from a nationally representative survey conducted among people living with HIV/AIDS in Cameroon. A multilevel mixed‐effect logistic model is employed to identify the factors associated with the incidence of informal payments. Results reveal that circa 3.05% of the surveyed patients incurred informal payments for the consultations made on the day of the survey. The amount paid informally represents up to four times the official tariff. Factors related to the following: (i) human resource management of the health facilities (e.g., task shifting); (ii) health professionals' perceptions vis‐à‐vis the remunerations of HIV care provision; and (iii) reception of patients (e.g., waiting time) significantly influence the probability of incurring informal payments. Also of note, the type of healthcare facilities is found to play a role: informal payments appear to be significantly lower in private non‐profit facilities compared with those belonging to public sector. Our findings allude to some policy recommendations that can help reduce the incidence of informal payments. Copyright © 2014 John Wiley & Sons, Ltd.     

The Use of Cost‐Effectiveness Analysis for Pediatric Immunization in Developing Countries

Context: Developing countries face critical choices for introducing needed, effective, but expensive new vaccines, especially given the accelerated need to decrease the mortality of children under age five and the increased immunization resources available from international donors. Cost‐effectiveness analysis (CEA) is a tool that decision makers can use for efficiently allocating expanding resources. Its use in developing countries, however, lags behind that in industrialized countries. Methods: We explored how CEA could be made more relevant to immunization policymaking in developing countries by identifying the limitations for using CEA in developing countries and the impact of donor funding on the CEA estimation. We conducted a comprehensive literature search using formal search protocols and hand searching indexed and gray literature sources. We then systematically summarized the application of CEA in industrialized and developing countries through thematic analysis, focusing on pediatric immunization and methodological and contextual issues relevant to developing countries. Findings: Industrialized and developing countries use CEA differently. The use of the Disability‐Adjusted Life Year (DALY) outcome measure and an alternative generalized cost‐effectiveness analysis approach is restricted to developing countries. In pediatric CEAs, the paucity of evaluations and the lack of attention to overcoming the methodological limitations pertinent to children's cognitive and development distinctiveness, such as discounting and preference characterization, means that pediatric interventions may be systematically understudied and undervalued. The ability to generate high‐quality CEA evidence in child health is further threatened by an inadequate consideration of the impact of donor funding (such as GAVI immunization funding) on measurement uncertainty and the determination of opportunity cost. Conclusions: Greater attention to pediatric interventions and donor funding in the conduct of CEA could lead to better policies and thus more worthwhile and good‐value programs to benefit children's health in developing countries.     

Use of child development assessment in early childhood education: early childhood practitioner and student attitudes toward formal and informal testing

Twenty early childhood practitioners (ECPs) and final-year Bachelor of Early Childhood Studies students completed a questionnaire about their use (or planned use) of formal and informal child development assessment instruments, their choice of specific instruments, and factors influencing decisions to conduct child development assessments within their early childhood programmes. While most ECPs and all students indicated use (or planned use) of informal assessment, 70% of students and only 10% of ECPs indicated use of formal assessment. Whereas ECPs identified 'ease of use' as most important, 'accuracy of the instrument' was most important to students. In deciding to use any assessment, students ranked 'identifies children at risk' as most important, compared with ECPs who ranked 'provides a good picture of children's development' as most important. Results are discussed in terms of their implications for the early childhood field and for pre-service training in child development assessment.     

Mixed care networks of community‐dwelling older adults with physical health impairments in the Netherlands

As part of long‐term care reforms, home‐care organisations in the Netherlands are required to strengthen the linkage between formal and informal caregivers of home‐dwelling older adults. Information on the variety in mixed care networks may help home‐care organisations to develop network type‐dependent strategies to connect with informal caregivers. This study first explores how structural (size, composition) and functional features (contact and task overlap between formal and informal caregivers) contribute to different types of mixed care networks. Second, it examines to what degree these network types are associated with the care recipients' characteristics. Through home‐care organisations in Amsterdam, the Netherlands, we selected 74 frail home‐dwelling clients who were receiving care in 2011–2012 from both informal and formal caregivers. The care networks of these older adults were identified by listing all persons providing help with five different types of tasks. This resulted in care networks comprising an average of 9.7 caregivers, of whom 67% were formal caregivers. On average, there was contact between caregivers within 34% of the formal–informal dyads, and both caregivers carried out at least one similar type of task in 29% of these dyads. A principal component analysis of size, composition, contact and task overlap showed two distinct network dimensions from which four network types were constructed: a small mixed care network, a small formal network, a large mixed network and a large formal network. Bivariate analyses showed that the care recipients’ activities of daily living level, memory problems, social network, perceived control of care and level of mastery differed significantly between these four types. The results imply that different network types require different actions from formal home‐care organisations, such as mobilising the social network in small formal networks, decreasing task differentiation in large formal networks and assigning co‐ordination tasks to specific dyads in large mixed care networks.     

Communicating uncertainty can lead to less decision satisfaction: a necessary cost of involving patients in shared decision making?

Background Given the large number of interventions of uncertain effectiveness, research on communicating uncertainty is needed to examine its impact on patients’ health decisions. Objective To examine physicians’ communication of uncertainty and its impact on patients’ decisions and decision satisfaction. Design, setting, and participants Participants included female patients seen in a breast health centre whose physicians were discussing a decision with them, with no clear ‘best’ choice based on outcome evidence. Main variables Decision communication was measured using the OPTION scale, a measure of the degree to which physicians involve patients in a decision‐making process. One‐to‐two weeks after the discussion, patients reported their satisfaction with the decision‐making process and their decision. Decisions were verified in medical charts with patient consent. Results Seventy‐five women agreed to participate (94% response rate). The mean translated score of the OPTION scale was 68.0 (SD 18.3), but only 33.2 (SD 19.1) for the uncertainty items. Among cancer patients, communicating uncertainty was negatively related to decision satisfaction (P < 0.002), and there was an interaction between patient involvement in decisions and communicating uncertainty in relation to patients’ decision satisfaction (P < 0.03). Discussion Communicating scientific uncertainty might lead to less decision satisfaction among women facing cancer treatment decisions; this could be a natural outcome of the decision making process. Involving patients in decisions might help them tolerate uncertainty. Conclusion Future studies should consider assessing other outcomes (e.g. knowledge, physician support) of the decision making process. There may be trade‐offs between acknowledging uncertainty and immediate decision satisfaction.     

Risk,trust and patients’ strategic choices of healthcare practitioners

Research on patients’ choice of healthcare practitioners has focussed on countries with regulated and controlled healthcare markets. In contrast, low‐ and middle‐income countries have a pluralistic landscape where untrained, unqualified and unlicensed informal healthcare providers (IHPs) provide significant share of services. Using qualitative data from 58 interviews in an Indian village, this paper explores how patients choose between IHPs and qualified practitioners in the public and formal private sectors. The study found that patients’ choices were structurally constrained by accessibility and affordability of care and choosing a practitioner from any sector presented some risk. Negotiation and engagement with risks depended on perceived severity of the health condition and trust in practitioners. Patients had low institutional trust in public and formal private sectors, whereas IHPs operated outside any institutional framework. Consequently, people relied on relational or competence‐derived interpersonal trust. Care was sought from formal private practitioners for severe issues due to high‐competence‐based interpersonal trust in them, whereas for other issues IHPs were preferred due to high relationship‐based interpersonal trust. The research shows that patients develop a strategic approach to practitioner choice by using trust to negotiate risks, and crucially, in low‐ and middle‐income countries IHPs bridge a gap by providing accessible and affordable care imbued with relational–interpersonal trust.     

Hospitalization Resource Use and Costs Before and After TIA and Stroke: Results from a Population-Based Cohort Study (OXVASC)

ObjectivesHigh hospitalization rates, prolonged length of stay, and increased risks of subsequent events mean a steep increase in health care usage after stroke. No study, however, has examined to what extent increased costs after transient ischemic attack (TIA) or stroke are due to hospitalizations for the initial event, recurrent events, and/or nonvascular hospitalizations, and how costs compare with the year prior to the event.MethodsWe studied patients in a population-based cohort study (Oxford Vascular Study) in the United Kingdom from 2003 to 2007. Hospitalization and cost details were obtained from patients’ individualized Hospital Episode Statistics records.ResultsA total of 295 incident TIA and 439 incident stroke patients were included. For patients with stroke, average costs increased from £1437 in the year pre-event to £6629 in the year post-event (P<0.0001). Sixty-four percent (£4224) of poststroke costs were due to hospitalizations linked to the index stroke, more than 30% of which were given nonvascular primary diagnoses on Hospital Episode Statistics, and £653 (10%) were due to hospitalizations linked to subsequent vascular events. For patients with TIA, costs increased from £876 1 year before the event to £2410 in the year post-event (P<0.0001). Patients with TIA incurred nonsignificantly higher costs due to hospitalizations linked to subsequent vascular events (£774) than for hospitalizations linked to the index TIA (£720).ConclusionsHospital costs increased after TIA or stroke, primarily because of increased initial cerebrovascular hospitalizations. The finding that costs due to nonvascular diagnoses also increased after TIA or stroke appears, in part, to be explained by the miscoding of TIA/stroke-related hospitalizations in electronic information systems.
