Strategies for improving patient safety culture in hospitals: a systematic review

Purpose To determine the effectiveness of patient safety culture strategies to improve hospital patient safety climate. Data sources Electronic search of the Cochrane Library, OVID Medline, Embase, CINAHL, proQuest and psychinfo databases, with manual searches of quality and safety websites, bibliographies of included articles and key journals. Study selection English language studies published between January 1996 and April 2011 that measured the effectiveness of patient safety culture strategies using a quantitative measure of patient safety climate in a hospital setting. Studies included were randomised controlled trials (RCTs), non-RCTs, controlled before and after studies, interrupted time series and historically controlled studies. Data extraction Data extraction and critical appraisal were conducted by two independent reviewers. Study design, intervention, level of application, setting, study participants, safety climate outcome measures and implementation lessons were extracted from each article. Results of data synthesis Over 2000 articles were screened, with 21 studies meeting the inclusion criteria, one cluster RCT, seven controlled before and after studies, and 13 historically controlled studies. There was marked methodological heterogeneity amongst studies. Impacts of 11 different strategies were reported. There was some evidence to support that leadership walk rounds (p=0.02) and multi-faceted unit-based programmes (p < 0.05) may have a positive impact on patient safety climate. Conclusions Despite strong face validity for a variety of patient safety culture strategies, there is limited evidence to support definitive impacts on patient safety climate outcomes. Organisations are advised to consider robust evaluation designs when implementing these potentially resource intensive strategies.

Fine-needle aspiration may miss a third of all malignancy in palpable thyroid nodules: a comprehensive literature review.

Background:Fine-needle aspiration (FNA) is currently the primary diagnostic procedure in diagnosing thyroid malignancy and guides surgeons on patient selection for thyroidectomy for thyroid nodules. Diagnostic sensitivity is reported to be approximately 80%; however, patients with negative FNA results do not necessarily undergo surgery and are often not considered in statistical analysis. This may lead to bias in previous reported sensitivity of FNA. The aim of this study was to assess the diagnostic performance attributes of FNA based on a comprehensive review and summary of previous literature. Methods:A comprehensive review of published literature from 1966 to 2005 was performed, using structured selection and appraisal methods to include all studies that have assessed the sensitivity of FNA for detecting thyroid malignancy in palpable thyroid nodules. A statistical modeling study was designed to estimate the possible true sensitivity and specificity of FNA. Results:Twelve studies fulfilled inclusion criteria and were included in the review. Only 1 study had greater than 25% of patients with negative FNA results who proceeded to thyroidectomy. Statistical modeling indicated that the sensitivity of FNA is highly dependent on the risk of malignancy in the patients with negative FNA results who did not undergo thyroidectomy; in the “same risk” scenario, where the risk of malignancy in the whole group with negative FNA result was assumed to be the same as that in patients with negative FNA results who underwent surgical biopsy; sensitivity could be as low as 66% (confidence interval [CI]: 65–68%). Conclusion:Based on existing reports, the true diagnostic attributes of FNA for thyroid malignancy in palpable nodules are uncertain and FNA could miss up to a third of all thyroid malignancy. Further research is required to investigate the incidence of malignancy in FNA negative cases and to determine the additive effect of clinical judgment.

Effectiveness of rehabilitation intervention in persons with multiple sclerosis: a randomised controlled trial

Objective: A stratified, randomised, waitlist controlled study over 12 months assessed the effectiveness of rehabilitation in persons with multiple sclerosis (MS) in an Australian community cohort. Methods: Patients with definite MS (n = 101) recruited from a tertiary hospital database, randomised to a treatment group (n = 49) for individualised rehabilitation programme or a control waitlist group (n = 52). Functional Independence Measure (FIM) was used to assess “activity” while the Multiple Sclerosis Impact Scale (MSIS-29) and General Health Questionnaire (GHQ-28) assessed “participation” and quality of life (QoL). Assessments were at baseline and 12 months. Results: Analysis of data from 98 patients (treatment n = 48, control n = 50) showed reduced disability in the treatment group, with statistically significant differences in post-treatment FIM motor scores for the two groups (p<0.001). There was a clinical and statistically significant improvement in FIM (motor) total scores (p<0.001), and the FIM motor domains of: transfer (p<0.001), locomotion (p<0.001), self-care (p<0.001) and the FIM cognitive subscale (p<0.016). In the treated group, 70.8% improved compared with 13% of controls. Significantly more patients in the control group deteriorated over the study period (58.7% vs 16.7%; p<0.001). There were no differences between the control and treatment group scores on the MSIS-physical (p = 0.18), MSIS-psychological (p = 0.45) or GHQ subscales. Conclusion: An individualised rehabilitation programme reduces disability in persons with MS compared with no intervention. The impact of rehabilitation on QoL needs further evaluation. More information on the effectiveness of the various components of the multidisciplinary rehabilitation programmes are now needed.

Caregiver strain and factors associated with caregiver self-efficacy and quality of life in a community cohort with multiple sclerosis

Purpose. To describe the level of caregiver strain and factors associated with caregiver self-efficacy and quality of life (QoL) in a community cohort with multiple sclerosis (MS). Method. A cross-sectional survey of 62 informal caregivers and 101 participants with confirmed MS and quantified physical and cognitive disability recruited from a tertiary hospital MS database. Structured interviews conducted at home using standardized assessments to measure: (i) Caregiver strain and subjective burden of care; (ii) participant with MS and caregiver QoL and self-efficacy; and (iii) participant with MS level of depression, anxiety and stress. Results. The mean caregiver age was 54 years (range 37 – 62). The mean caregiver strain score was 5.63 (SD 3.63). Twenty-six of 62 (42%) caregivers reported strain for items such as emotional adjustments, demands on time, change in personal plan and disrupted sleep. Caregiver burden was higher in those caring for the more severely affected persons with MS, especially those with higher depression, anxiety and stress levels. The caregiver strain correlated with a lower QoL in both the person with MS and their caregiver, but not with their self-efficacy scores. Conclusion. Caregivers of persons with MS reporting high levels of caregiver strain experienced a lower QoL and were caring for persons with MS with a lower QoL and higher levels of depression and anxiety. Interventions to reduce caregiver strain and burden in those at risk are necessary to reduce poor outcomes among both caregivers and care recipients with MS.

Feasibility and Outcomes of a Home-Based Exercise Program on Improving Balance and Gait Stability in Women With Lower-Limb Osteoarthritis or Rheumatoid Arthritis: A Pilot Study

UNLABELLED Williams SB, Brand CA, Hill KD, Hunt SB, Moran H. Feasibility and outcomes of a home-based exercise program on improving balance and gait stability in women with lower-limb osteoarthritis or rheumatoid arthritis: a pilot study. OBJECTIVE To evaluate the feasibility and gait stability and balance outcomes of a 4-month individualized home exercise program for women with arthritis. DESIGN Pre-post interventional study. SETTING General community. PARTICIPANTS Women (N=49) (volunteers) with lower-limb osteoarthritis or lower-limb rheumatoid arthritis were enrolled. Only 39 subjects were eligible and completed the study. INTERVENTION After completion of the initial assessment, all participants received home balance exercises from an experienced physiotherapist based on assessment findings and exercises available from commercially available kits. All measures were repeated 4 months later. MAIN OUTCOME MEASURES Falls risk (Falls Risk of Older People-Community Setting) and balance measures. RESULTS Thirty-nine women (mean age, 69.3y; 95% confidence interval, 65.7-72.9) completed the 4-month program. At baseline, 64% of participants reported falling in the preceding 12 months, and the average falls risk (Falls Risk of Older People-Community Setting) score was 14.5, with 42% rated as moderate risk (16-23). Participants achieved improved performance on most balance and related measures after the exercise program, including falls risk (P=.01), activity levels (P=.015), fear of falling (P=.022), functional reach test (P=.001), rising index for sit to stand (P=.001), step width in walking (P=.001), and body mass index (P=.006). CONCLUSIONS An individualized balance training home exercise program is feasible for older women with osteoarthritis or rheumatoid arthritis and may improve stability during walking and other functional activities.

How reliably do rheumatologists measure shoulder movement

Objective: To assess the intrarater and interrater reliability among rheumatologists of a standardised protocol for measurement of shoulder movements using a gravity inclinometer. Methods: After instruction, six rheumatologists independently assessed eight movements of the shoulder, including total and glenohumeral flexion, total and glenohumeral abduction, external rotation in neutral and in abduction, internal rotation in abduction and hand behind back, in random order in six patients with shoulder pain and stiffness according to a 6×6 Latin square design using a standardised protocol. These assessments were then repeated. Analysis of variance was used to partition total variability into components of variance in order to calculate intraclass correlation coefficients (ICCs). Results: The intrarater and interrater reliability of different shoulder movements varied widely. The movement of hand behind back and total shoulder flexion yielded the highest ICC scores for both intrarater reliability (0.91 and 0.83, respectively) and interrater reliability (0.80 and 0.72, respectively). Low ICC scores were found for the movements of glenohumeral abduction, external rotation in abduction, and internal rotation in abduction (intrarater ICCs 0.35, 0.43, and 0.32, respectively), and external rotation in neutral, external rotation in abduction, and internal rotation in abduction (interrater ICCs 0.29, 0.11, and 0.06, respectively). Conclusions: The measurement of shoulder movements using a standardised protocol by rheumatologists produced variable intrarater and interrater reliability. Reasonable reliability was obtained only for the movement of hand behind back and total shoulder flexion.

Vitamin E is ineffective for symptomatic relief of knee osteoarthritis: a six month double blind, randomised, placebo controlled study

OBJECTIVE There is a putative role for antioxidant treatment in osteoarthritis (OA) based on animal, epidemiological, and human clinical studies. Vitamin E, a fat soluble vitamin, is one of the major dietary antioxidants. Short term clinical studies using vitamin E in the form of α-tocopherol suggested a benefit over placebo of similar dimension to that of diclofenac for relief of OA pain. METHODS A six month, double blind, randomised, placebo controlled study of vitamin E 500 IU/day was carried out. Primary outcome measures were pain, stiffness, and function. Statistical analysis was performed on an intention to treat basis. RESULTS 77 patients were included in the study. Vitamin E showed no benefit over placebo at one month, three months, or six months for any of the outcome measures. The placebo group had higher pain levels (p=0.15) and body mass index (p=0.03) at baseline, and lower pain levels (p=0.02) at completion of the study. Radiological score, exercise score, age, or antioxidant intake at baseline or six months did not differ between the groups. The reasons for the better performance of the placebo group are uncertain but may relate to the initially higher pain score and subsequent regression to the mean. CONCLUSIONS Vitamin E shows no benefit for the management of symptomatic knee OA. The role of vitamin E in preventing OA progression is currently under investigation.

Review article: Leaving the emergency department without being seen

Patients who leave the ED without being seen (LWBS) are unlikely to be satisfied with the quality of the service provided and might be at risk from conditions that have not been assessed or treated. We therefore examined the available research literature to inform the following questions: (i) In patients who attend for ED care, what factors are associated with the decision to LWBS? (ii) In patients who attend for ED care, are there adverse health outcomes associated with the decision to LWBS? (iii) Which interventions have been used to try to reduce the number of patients who attend for ED care and LWBS? From the available literature, there was insufficient evidence to draw firm conclusions; however, the literature does suggest that patients who LWBS have conditions of lower urgency and lower acuity, are more likely to be male and younger, and are likely to identify prolonged waiting times as a central concern. LWBS patients generally have very low rates of subsequent admission, and reports of serious adverse events are rare. Many LWBS patients go on to seek alternative medical attention, and they might have higher rates of ongoing symptoms at follow‐up. Further research is recommended to include comprehensive cohort or well‐designed case–control studies. These studies should assess a wide range of related factors, including patient, hospital and other relevant factors. They should compare outcomes for groups of LWBS patients with those who wait and should include cross‐sectoral data mapping to truly detect re‐attendance and admission rates.

Do patient reported outcome measures in hip and knee arthroplasty rehabilitation have robust measurement attributes? A systematic review.

OBJECTIVE The aim of this study was to systematically review and compare the measurement attributes of multidimensional, patient-reported outcome measures used in hip and knee arthroplasty rehabilitation. METHODS A search of PubMed, CINAHL, Cochrane Central Registry, SCOPUS and PEDro databases up to December 2009 identified the validation studies. The quality of the measurement properties were assessed based on the Terwee and Bot criteria, and Scientific Advisory Committee of the Medical Outcomes Trust guidelines. RESULTS A total of 68 studies examining 28 instruments were identified. Three instruments had positive ratings for content validity. None of the instruments satisfied both factor analysis and Cronbachs α criteria for internal consistency. Four measures were positively-rated for agreement. Nine tools had positive ratings for construct validity. Twenty-four of the instruments had indeterminate ratings for responsiveness to clinical change. Only certain subscales of 2 instruments were positively-rated for responsiveness to clinical change. CONCLUSION A wide variety of multidimensional patient-reported instruments has been used to assess rehabilitation outcomes after hip and knee arthroplasty, but information about their measurement attributes in these populations is inadequate. More data are needed to clarify their reproducibility and responsiveness to clinical change. :

Clinical practice guidelines for the management of delirium in older people in Australia

Delirium is a common and serious condition which is often overlooked or misdiagnosed in older people. In 2006, the first set of national clinical practice guidelines for the management of delirium in older people were developed. This paper provides an abbreviated version of the guideline document which includes recommendations for the detection of delirium (diagnosis and screening), assessment and prediction of risk factors for delirium, prevention of delirium and interventions to manage people with delirium. The guidelines reflect the available evidence base and highlight the limited high level research in delirium care, particularly in the areas of symptom management and screening for delirium.
