Effects of a Province-wide Triaging System for TIA: The ASPIRE Intervention.

BACKGROUND AND OBJECTIVES: Urgent transient ischemic attack (TIA) management to reduce stroke recurrence is challenging, particularly in rural and remote areas. In Alberta, Canada, despite an organized stroke system, data from 1999 to 2000 suggested that stroke recurrence after TIA was as high as 9.5% at 90 days. Our objective was to determine whether a multifaceted population-based intervention resulted in a reduction in recurrent stroke after TIA. METHODS: In this quasi-experimental health services research intervention study, we implemented a TIA management algorithm across the entire province, centered around a 24-hour physician's TIA hotline and public and health provider education on TIA. From administrative databases, we linked emergency department discharge abstracts to hospital discharge abstracts to identify incident TIAs and recurrent strokes at 90 days across a single payer system with validation of recurrent stroke events. The primary outcome was recurrent stroke; with a secondary composite outcome of recurrent stroke, acute coronary syndrome, and all-cause death. We used an interrupted time series regression analysis of age-adjusted and sex-adjusted stroke recurrence rates after TIA, incorporating a 2-year preimplementation period (2007-2009), a 15-month implementation period, and a 2-year postimplementation period (2010-2012). Logistic regression was used to examine outcomes that did not fit the time series model. RESULTS: We assessed 6,715 patients preimplementation and 6,956 patients postimplementation. The 90-day stroke recurrence rate in the pre-Alberta Stroke Prevention in TIA and mild Strokes (ASPIRE) period was 4.5% compared with 5.3% during the post-ASPIRE period. There was neither a step change (estimate 0.38; p = 0.65) nor slope change (parameter estimate 0.30; p = 0.12) in recurrent stroke rates associated with the ASPIRE intervention implementation period. Adjusted all-cause mortality (odds ratio 0.71, 95% CI 0.56-0.89) was significantly lower after the ASPIRE intervention. DISCUSSION: The ASPIRE TIA triaging and management interventions did not further reduce stroke recurrence in the context of an organized stroke system. The apparent lower mortality postintervention may be related to improved surveillance after events identified as TIAs, but secular trends cannot be excluded. CLASSIFICATION OF EVIDENCE: This study provides Class III evidence that a standardized population-wide algorithmic triage system for patients with TIA did not reduce recurrent stroke rate.

Quality of care and mortality are worse in chronic kidney disease patients living in remote areas.

Many patients with non-dialysis dependent chronic kidney disease (CKD) live far from the closest nephrologist; although reversible, this might constitute a barrier to optimal care. In order to evaluate outcomes, we selected 31,452 outpatients older than 18 years with an estimated glomerular filtration rate (eGFR) less than 45 ml/min per 1.73 m² who had serum creatinine measured at least once during 2005 in Alberta, Canada. We then used logistic regression to examine the association between outcomes of 6545 patients who lived more than 50 km from the nearest nephrologist. Over a median follow-up of 27 months, 7684 participants died and 15,075 were hospitalized at least once. Compared with those living within 50 km, those further away were significantly less likely to visit a nephrologist or a multidisciplinary CKD clinic within 18 months of the index measurement of the eGFR. Similarly, remote dwellers with diabetes were significantly less likely to have hemoglobin A1c evaluated within 1 year of the index eGFR measurement, to have urinary albumin assessed biannually, or to receive an angiotensin converting enzyme inhibitor or receptor blocker in the setting of diabetes or proteinuria. Remote-dwelling participants were also significantly more likely to die or be hospitalized during follow-up than those living closer. Thus, among people with CKD, remote dwellers were less likely to receive specialist care, recommended laboratory testing, and appropriate medications, and were more likely to die or be hospitalized compared with those living closer to a nephrologist.

Learning to lead: a review and synthesis of literature examining health care managers' use of knowledge.

BACKGROUND: Scholarship cites health care managers (HCMs) as not using research evidence in their management practice. The purpose of this review was to evaluate the effectiveness of interventions to enhance HCMs use of research evidence in practice. METHODS: We carried out a systematic review and focus groups to validate the review findings. We searched 10 electronic databases for studies reporting on interventions for HCMs to enhance research utilization in their practice. Qualitative studies were analysed using Hoon's approach to meta-synthesis. RESULTS: Seven, primarily qualitative, studies of varying quality (reported in 11 articles) met our inclusion criteria. Interventions to enhance research use by HCMs included: informal and formal training, computer-based application, executive-level knowledge translation activities and residency programmes. Studies did not report efficacy of interventions or impacts of increasing managers' use of research on staff or patient outcomes. Meta-synthesis yielded four contextual factors influencing the perceived effectiveness of interventions to enhance research use by HCMs: organizational culture, competing priorities, time as a resource and capacity building. Included studies differed in how they defined research and demonstrated varying understandings of research among HCMs, limiting the generalizability of work in this field. CONCLUSIONS: Healthcare managers are increasingly called upon to make evidence-based decisions in practice, but the small number of studies and diverse strategies employed hinder our ability to identify any intervention to increase use of evidence as superior. Future studies in this area should clearly articulate the definition of research evidence they base their decisions on. Registration: PROSPERO (CRD42014006256).

Institutionalizing pain management: the Post-Operative Pain Management Quality Improvement Project.

Clinical practice and quality improvement (QI) guidelines for acute postoperative pain management have been developed to address the well-documented problem of undertreatment of postoperative pain. The Post-Operative Pain Management Quality Improvement Project (the POP Project) was initiated to determine whether an intervention designed to support hospitals in the development of QI efforts would lead to improvements in structures, processes, and outcomes consistent with recommended guidelines. A nationwide sample of 233 hospitals joined the project. The intervention consisted of written resource materials accompanied by support services that included an e-mail list server, a resource Web page, and assistance from POP Project staff via telephone. Data regarding critical structures, processes (practice patterns), and patient outcomes were collected at baseline before the intervention began and at follow-up 12 to 18 months later. Results showed a statistically significant increase from baseline (45%) to follow-up (72%) in the presence of structural elements that are critical to improving pain management. There were statistically significant improvements in practices including documented use of pain rating scales, decreased use of intramuscular opioids, and increased use of nonpharmacologic strategies. Patient survey data showed no change in pain outcomes. Evaluation data showed that 70% of hospitals were very or extremely satisfied with their participation in the POP Project and 90% of them planned to continue efforts to improve pain management after the POP Project ended. Further research is needed to determine how to translate the excellent results obtained for structure and process into meaningful outcomes for patients.

The Alberta Stroke Prevention in TIAs and mild strokes (ASPIRE) intervention: rationale and design for evaluating the implementation of a province-wide TIA triaging system.

RATIONALE: Stroke risk after transient ischaemic attack is high and, it is a challenge worldwide to provide urgent assessment and preventive services to entire populations. AIMS: To determine whether a province-wide transient ischaemic attack Triaging algorithm and transient ischaemic attack hotline (the Alberta Stroke Prevention in transient ischaemic attacks and mild strokes intervention) can reduce the rate of stroke recurrence following transient ischaemic attack across the population of Alberta, Canada (population 3·7 million, 90-day rate of post-stroke transient ischaemic attack currently 9·5%). It also seeks to improve upon current transient ischaemic attack triaging rules by incorporating time from symptom onset as a predictive variable. DESIGN: The transient ischaemic attack algorithm and hotline were developed with a broad consensus of clinicians, patients, policy-makers, and researchers and based on local adaptation of the work of others and research and insights developed within the province. Because neither patient-level nor region-level randomization was possible, we conducted a quasi-experimental design examining changes in the post-transient ischaemic attack rate of stroke recurrence before and after the 15-month implementation period using an interrupted time-series regression analysis. The design controls for changes in case-mix, co-interventions, and secular trends. A prospective transient ischaemic attack cohort will also be concurrently created with telephone follow-up at seven-days and 90 days as well as passive follow-up over the longer term using linkages to provincial healthcare administrative databases. STUDY OUTCOMES: The primary outcome measure is the change in recurrence rate of stroke following transient ischaemic attack at seven-days and 90 days, comparing a period of two-years before vs. two-years after the intervention is implemented. All cases of recurrent stroke will be validated. Secondary outcomes include functional status, hospitalizations, morbidity, and mortality. CONCLUSIONS: We are undertaking a rigorous evaluation of a population-based approach to improving quality of transient ischaemic attack care. Whether positive or negative, our work should provide important insights for all potential stakeholders.

Stop the pain! A nation-wide quality improvement programme in paediatric oncology pain control.

INTRODUCTION: Little is known about the impact of translation of pain management clinical practice guidelines on pain control in paediatrics. In an effort to overcome this, a longitudinal, nation-wide, multi-centre paediatric quality improvement (QI) study was initiated by the German Society of Pediatric Haematology and Oncology (GPOH) entitled Schmerz-Therapie in der Onkologischen Paediatrie (STOP). OBJECTIVE: The project's primary major aims were to improve paediatric oncology pain control in Germany, and to evaluate the project's impact on the pain management quality. To achieve these aims, STOP encompassed six sequential phases to evaluate present practice, develop recommendations for practical pain control, actively engage participants in improvement strategies, and assess change. The purpose of this paper is to briefly describe STOP in its entirety, report on comparisons between active quality management (QM) departments that actively participated in the project and non-active QM departments regarding differences in pain control, patients' and parents' perspectives on pain control and health professionals' knowledge, and to discuss the impact of STOP as a whole. METHODS: Four hypotheses were examined: (1) changes in health care professionals' knowledge on pain in paediatric oncology and pain management after a three-year period (2) impact of active participation in the STOP-project; (3) differences in patients' and parents' perspective in active QM versus non-active QM departments; (4) impact of the STOP-project on the health care professionals' knowledge in active QM versus non-active QM departments. Data included surveys, interviews, and standardised pre-/post-intervention documentation of pain control. All German paediatric oncology departments were invited to participate. The prime means of intervention was education (printed material, passive participation; additional lectures and feed-back, active participation). Quality indicators were defined and compared with regards to the four hypotheses. RESULTS: Sixty-eight departments participated passively. Eight departments participated actively, enrolling 224 patients (median age, 9 years) and documenting a total of 2265 treatment days. In the areas addressed, all health professionals demonstrated increases in knowledge on pain and pain control after a three-year period. STOP objectively improved pain control in the actively participating departments. Painful modes of drug administration were used less frequently; the usage of mixed opioid agonists-antagonists was reduced; the physicians' knowledge of the treatment of neuropathic pain increased; pain ratings significantly decreased, and less episodes of strong pain were observed. There was a significant increase in the proportion of health-care professionals who post-interventionally judged that pain therapy had been initiated earlier and at exactly the right time. Neither patients nor parents felt, however, that there was any quality improvement. According to participants' self-assessment, STOP improved practical pain management in actively participating departments, while in passively participating departments the change to the better was negligible. CONCLUSION: STOP predominantly aimed at and succeeded in the improvement of structure, process and outcome quality. With regard to patients' and parents' opinions, the interview tools might have been unsuited to measure the quality of pain control, or STOP was insufficient to improve pain control to a magnitude significant to the patient.
