Compliance of Secondary Prevention Strategies in Coronary Artery Disease Patients with and without Diabetes Mellitus - A Cross-Sectional Analytical Survey from Kerala, India.

CONTEXT: There is limited data related to compliance of secondary prevention strategies for coronary artery diseases (CAD) among patients with and without diabetes. OBJECTIVES: The objective was to compare compliance to secondary prevention strategies for CAD including smoking cessation, weight management, blood pressure (BP) control, Low density lipoprotein (LDL) cholesterol control and adequate physical activity between patients with and without diabetes. SETTINGS AND DESIGN: This is a hospital-based cross-sectional analytical study. METHODS AND MATERIALS: The study questionnaire was used to collect data through interviews of CAD patients. Compliance to secondary prevention strategies was documented using European Society of Cardiology guidelines. STATISTICAL ANALYSIS: We used modified Poisson model to estimate adjusted prevalence ratios (Adj. PR) for estimating compliance. RESULTS: Among 1,206 participants with CAD, 609 (50.5%) had diabetes. The Adj. PR s for three targets - smoking cessation (Adj. PR 1.01, 95% CI 0.97, 1.06, P 0.50), ideal BMI (Adj. PR 0.99, 95% CI 0.92, 1.09, P 0.99) and adequate physical activity (Adj. PR 1.12, 95% CI 0.97, 1.29, P 0.12) showed no significant difference between the groups. There was poor BP control in patients with diabetes compared to those without the same (Adj. PR 0.19, 95% CI 0.15, 0.23, P < 0.0001). LDL cholesterol control was better in patients with diabetes in comparison to those without the same (Adj. PR 1.19, 95% CI 1.08, 1.31, P 0.0005). CONCLUSION: The compliance for secondary prevention of CAD among patients with diabetes is similar to those without diabetes except for poor control of hypertension and better control of LDL cholesterol.

Tailored Versus Standard Hydration to Prevent Acute Kidney Injury After Percutaneous Coronary Intervention: Network Meta-Analysis.

Background Contrast-induced acute kidney injury (CI-AKI) is a serious complication after percutaneous coronary intervention. The mainstay of CI-AKI prevention is represented by intravenous hydration. Tailoring infusion rate to patient volume status has emerged as advantageous over fixed infusion-rate hydration strategies. Methods and Results A systematic review and network meta-analysis with a frequentist approach were conducted. A total of 8 randomized controlled trials comprising 2312 patients comparing fixed versus tailored hydration strategies to prevent CI-AKI after percutaneous coronary intervention were included in the final analysis. Tailored hydration strategies included urine flow rate-guided, central venous pressure-guided, left ventricular end-diastolic pressure-guided, and bioimpedance vector analysis-guided hydration. Primary endpoint was CI-AKI incidence. Safety endpoint was incidence of pulmonary edema. Urine flow rate-guided and central venous pressure-guided hydration were associated with a lower incidence of CI-AKI compared with fixed-rate hydration (odds ratio [OR], 0.32 [95% CI, 0.19-0.54] and OR, 0.45 [95% CI, 0.21-0.97]). No significant difference in pulmonary edema incidence was observed between the different hydration strategies. P score analysis showed that urine flow rate-guided hydration is advantageous in terms of both CI-AKI prevention and pulmonary edema incidence when compared with other approaches. Conclusions Currently available hydration strategies tailored on patients' volume status appear to offer an advantage over guideline-supported fixed-rate hydration for CI-AKI prevention after percutaneous coronary intervention. Current evidence suggests that urine flow rate-guided hydration as the most convenient strategy in terms of effectiveness and safety.

Postoperative Outcomes Following Total Hip and Knee Arthroplasty in Patients with Pain Catastrophizing, Anxiety, or Depression.

BACKGROUND: The relationship among pain catastrophizing, emotional disorders, and total joint arthroplasty (TJA) outcomes is an emerging area of study. The purpose of this study is to examine the association of these factors with 1-year postoperative pain and functional outcomes. METHODS: A prospective cohort study of preoperative TJA patients using the Pain Catastrophizing Scale and Hospital Anxiety and Depression Scale (HADS-A/HADS-D) was conducted. Postoperative outcomes included Visual Analog Scale (VAS) pain, Oxford, Harris Hip (HHS) and Knee Society (KSS) scores. Median regression was used to assess the pattern of relationship among preoperative clinically relevant catastrophizing (CRC) pain, abnormal HADS, and 1-year postoperative outcomes. RESULTS: We recruited 463 TJA patients, all of which completed 1-year follow-up. At 1 year, CRC-rumination (adjusted median difference 1; 95% confidence interval [CI] 0.31-1.69, P = .005) and abnormal HADS-A (adjusted median difference 1; 95% CI 0.36-1.64, P = .002) were predictors of VAS pain, CRC magnification a predictor of HHS/KSS (adjusted median difference 1.3; 95% CI 5.23-0.11, P = .041), and abnormal HADS-A a predictor of Oxford (adjusted median difference 3.68; 95% CI 1.38-5.99, P = .002). CRC patients demonstrated inferior VAS pain (P = .001), Oxford (P < .0001), and HHS/KSS (P = .025). Abnormal HADS patients demonstrated inferior postoperative VAS (HADS-A, P = .025; HADS-D, P = .030) and Oxford (HADS-A, P = .001; HADS-D, P = .030). However, patients with CRC experienced significant improvement in VAS, Oxford, and HHS/KSS (P < .05) from preoperative to 1 year. Similarly, patients with abnormal HADS showed significant improvement in VAS pain and HHS/KSS (P < .05). CONCLUSION: TJA patients who are anxious, depressed, or pain catastrophizing have inferior preoperative and postoperative pain and function. However, as compared to their preoperative status, clinically significant improvement can be expected following hip/knee arthroplasty.

Health-Related Quality of Life of Coronary Artery Disease Patients under Secondary Prevention: A Cross-Sectional Survey from South India.

BACKGROUND: Health-related quality of life (HRQOL) is emerging as an important outcome among patients with documented coronary artery disease (CAD). The primary objective of this study was to report the HRQOL of CAD patients under secondary prevention-related treatment and follow-up using the 36-Item Short Form (SF-36) tool. METHODS: This was an analytical cross-sectional survey done in a hospital/clinic setting. We recruited CAD patients 30 to 80 years old with 1 to 6 years of follow-up. Patients self-reported HRQOL using SF-36. RESULTS: We recruited 1206 patients, among whom 879 (72.9%) were male. The mean age of patients was 61.3 (9.6) years. Mean (± standard deviation) scores for physical functioning, role limitations due to physical health, pain, and general health were 66.48 ± 29.41, 78.96 ± 28.01, 80.96 ± 21.15, and 51.49 ± 20.19, respectively. The scores for role limitations due to emotional problems, energy/fatigue, emotional well-being, and social functioning were 76.62 ± 28.0, 66.18 ± 23.92, 76.91 ± 20.47, and 74.49 ± 23.55. In subgroup analysis, age, sex, type of CAD, and treatment showed no significant association with any of the 8 domains of QOL. In addition, hypertension and diabetes showed no significant association with the individual domains of HRQOL. CONCLUSION: Patients with coronary artery disease under secondary prevention-related treatment have suboptimal HRQOL under both physical and mental domains. The role of demographic factors, comorbidities, disease subtypes, and treatment options in modifying HRQOL among patients with CAD appears to be minimal.

Compliance to secondary prevention strategies for coronary artery disease: a hospital-based cross-sectional survey from Ernakulam, South India.

OBJECTIVES: The primary objective of the study was to report the compliance to secondary prevention strategies for coronary artery disease (CAD), such as smoking cessation, weight management, low-density lipoprotein (LDL) cholesterol control, blood pressure control, glycaemic control, physical activity and cardiovascular drug therapy from a resource-limited setting. DESIGN: Analytical cross-sectional survey with data collection using questionnaire administered by study personnel. SETTING: Institutional-two tertiary care hospitals and two cardiology clinics. PARTICIPANTS: Patients in the age group of 30-80 years with documented CAD with a minimum of 1 year and a maximum of 6 years of follow-up after diagnosis. MAIN OUTCOME MEASURES: The main outcome measures were the prevalence of individual compliance to secondary prevention strategies for CAD such as smoking cessation, weight management, LDL cholesterol control, blood pressure control, glycaemic control, physical activity and cardiovascular drug therapy. The secondary outcomes were the association of secondary prevention strategies with age, sex, domicile, socioeconomic status, insurance and type of treatment. RESULTS: We recruited a total of 1206 patients among whom 879 (72.9%) were males. The median age of patients was 62 (14) years. The compliance to smoking cessation was 93.86% (95% CI 91.66% to 96.06%), ideal body mass index was 63.76% (95% CI 61.05% to 66.47%), blood pressure control was 65.11% (95% CI 62.42% to 67.80%), LDL compliance was 36.50% (95% CI 33.18% to 39.82%), diabetes control was 51.23% (95% CI 46.10% to 56.36%) and adequate physical activity was 39.22% (95% CI 36.46% to 41.98%)respectively. Reported compliance for cardiovascular drugs therapy was 96% for antiplatelets, 89.4% for statins, 68.2% for beta blockers, 37.7% for renin angiotensin aldosterone system blockers, 81.28% for oral hypoglycaemic agents and 22% for insulin therapy. CONCLUSION: Compliance to secondary prevention strategies for CAD in resource limited settings are moderate. This needs further improvement for better outcomes related to CAD in future.

Incidence and risk factors for falls among community-dwelling elderly subjects on a 1-year follow-up: a prospective cohort study from Ernakulam, Kerala, India.

OBJECTIVES: There is limited knowledge regarding epidemiology and risk of falls among the elderly living in low-income and middle-income countries. In this situation, the current study aims to report the incidence of falls and associated risk factors among free living elderly population from Kerala, India. DESIGN: Prospective cohort study with stratified random cluster sampling. SETTING: The study location was Ernakulam, Kerala, India, and we collected information via house visits using a questionnaire. During the research, the subjects were followed up prospectively for 1 year by phone at intervals of 3 months and missing subjects were contacted by house visits. PARTICIPANTS: Community-dwelling elderly above 65 years of age. RESULTS: We recruited a total of 1000 participants out of which a total of 201 (20.1%) subjects reported a fall during the follow-up. The incidence rate of falls was 31 (95% CI 27.7 to 34.6) per 100 person-years. Female sex (OR 1.48, 95% CI 1.05 to 2.10, p=0.027), movement disorders including Parkinsonism (OR 2.26, 95% CI 1.00 to 5.05, p=0.048), arthritis (OR 1.48, 95% CI 1.05 to 2.09, p=0.026), dependence in basic activities of daily living (OR, 3.49, 95% CI 2.00 to 6.09, p<0.001), not using antihypertensive medications (OR, 1.53, 95% CI 1.10 to 2.13, p=0.012), living alone during daytime (OR 3.27, 95% CI 1.59 to 6.71, p=0.001) and a history of falls in the previous year (OR, 2.25, 95% CI 1.60 to 3.15, p<0.001) predicted a fall in the following year. CONCLUSIONS: One in five community-dwelling senior citizen fall annually and one in four who fall are prone to fall again in the following year. Interventions targeting falls among the elderly need to focus on modifiable risk factors such as living alone during daytime, movement disorders, arthritis and dependence on basic activities of daily living.

Antithrombotic treatment after coronary artery bypass graft surgery: systematic review and network meta-analysis.

OBJECTIVE: To assess the effects of different oral antithrombotic drugs that prevent saphenous vein graft failure in patients undergoing coronary artery bypass graft surgery. DESIGN: Systematic review and network meta-analysis. DATA SOURCES: Medline, Embase, Web of Science, CINAHL, and the Cochrane Library from inception to 25 January 2019. ELIGIBILITY CRITERIA: for selecting studies Randomised controlled trials of participants (aged ≥18) who received oral antithrombotic drugs (antiplatelets or anticoagulants) to prevent saphenous vein graft failure after coronary artery bypass graft surgery. MAIN OUTCOME MEASURES: The primary efficacy endpoint was saphenous vein graft failure and the primary safety endpoint was major bleeding. Secondary endpoints were myocardial infarction and death. RESULTS: This review identified 3266 citations, and 21 articles that related to 20 randomised controlled trials were included in the network meta-analysis. These 20 trials comprised 4803 participants and investigated nine different interventions (eight active and one placebo). Moderate certainty evidence supports the use of dual antiplatelet therapy with either aspirin plus ticagrelor (odds ratio 0.50, 95% confidence interval 0.31 to 0.79, number needed to treat 10) or aspirin plus clopidogrel (0.60, 0.42 to 0.86, 19) to reduce saphenous vein graft failure when compared with aspirin monotherapy. The study found no strong evidence of differences in major bleeding, myocardial infarction, and death among different antithrombotic therapies. The possibility of intransitivity could not be ruled out; however, between-trial heterogeneity and incoherence were low in all included analyses. Sensitivity analysis using per graft data did not change the effect estimates. CONCLUSIONS: The results of this network meta-analysis suggest an important absolute benefit of adding ticagrelor or clopidogrel to aspirin to prevent saphenous vein graft failure after coronary artery bypass graft surgery. Dual antiplatelet therapy after surgery should be tailored to the patient by balancing the safety and efficacy profile of the drug intervention against important patient outcomes.

Health-related quality of life (HRQOL) in children and adolescents with congenital heart disease: a cross-sectional survey from South India.

OBJECTIVE: There are limited data on health-related quality of life (HRQOL) for children and adolescents with uncorrected congenital heart disease (CHD) from low-income and middle-income countries where late presentation is common. We sought to compare HRQOL of children and adolescents with uncorrected CHD to that of controls using the Pediatric Quality of Life Inventory (PedsQL 4.0). METHODS: The study design is a cross-sectional analytical survey. The study setting was (1) Hospital-based survey of patients with CHD and their parents. (2) Community survey of controls and their parents. Subjects included (1) Children/adolescents with CHD between the ages of 2 years and 18 years and their parents enrolled in a previous study (n=308). (2) Unmatched community controls (719 children/adolescents, aged 2-18 years) and their parents. Participants were given PedsQL 4.0 to fill out details. Parents assisted children 5-7 years of age in filling the questionnaires. Children younger than 5 years had only parent-reported HRQOL and those above 5 years had both self-reported and parent-reported HRQOL. RESULTS: The median (IQR) total generic HRQOL from self-reports for CHD subjects and controls were 71.7 (62.0, 84.8) and 91.3 (82.6, 95.7), respectively. The corresponding figures for parent-reports were 78.3 (63.0, 90.5) and 92.4 (87.0, 95.7) respectively. The adjusted median difference was -20.6 (99% CI -24.9 to -16.3, p<0.001) for self-reported and -14.1 (99% CI -16.7 to -11.6, p<0.001) for parent-reported total HRQOL between patients with CHD and controls. Cardiac-specific HRQOL by self-reports was 75.0 (53.6, 92.9) for heart problems, 95.0 (73.8, 100.0) for treatment barriers, 83.3 (66.7, 100.0) for physical appearance, 87.5 (62.5, 100.0) for treatment-related anxiety, 91.7 (68.8, 100.0) for cognitive problems and 83.3 (66.7, 100.0) for communication. The values for parent-reports were 71.4 (53.6, 85.7), 100.0 (75.0, 100.0), 100.0 (75.0, 100.0), 81.3 (50.0, 100.0), 100.0 (81.2, 100.0) and 83.3 (50.0, 100.0), respectively. CONCLUSIONS: Children and adolescents with uncorrected CHD reported significant reductions in overall quality of life compared with controls.

Antithrombotic therapy in patients receiving saphenous vein coronary artery bypass grafts: a protocol for a systematic review and network meta-analysis.

INTRODUCTION: The current evidence for the prevention of saphenous vein graft failure (SVGF) after coronary artery bypass graft (CABG) surgery consists of direct head-to-head comparison of treatments (including placebo) in randomised-controlled trials (RCTs) and observational studies. However, summarising the evidence using traditional pairwise meta-analyses does not allow the inclusion of data from treatments that have not been compared head to head. Exclusion of such comparisons could impact the precision of pooled estimates in a meta-analysis. Hence, to address the challenge of whether aspirin alone or in addition to another antithrombotic agent is a more effective regimen to improve SVG patency, a network meta-analysis (NMA) is necessary. The objectives of this study are to synthesise the available evidence on antithrombotic agents (or their combination) and estimate the treatment effects among direct and indirect treatment comparisons on SVGF and major adverse cardiovascular events, and to generate a treatment ranking according to their efficacy and safety outcomes. METHODS: We will perform a systematic review of RCTs evaluating antithrombotic agents in patients undergoing CABG. A comprehensive English literature search will be conducted using electronic databases and grey literature resources to identify published and unpublished articles. Two individuals will independently and in duplicate screen potential studies, assess the eligibility of potential studies and extract data. Risk of bias and quality of evidence will also be evaluated independently and in duplicate. We will investigate the data to ensure its suitability for NMA, including adequacy of the outcome data and transitivity of treatment effects. We plan to estimate the pooled direct, indirect and the mixed effects for all antithrombotic agents using a NMA. ETHICS AND DISSEMINATION: Due to the nature of the study, there are no ethical concerns nor informed consent required. We anticipate that this NMA will be the first to simultaneously assess the relative effects of multiple antithrombotic agents in patients undergoing CABG. The results of this NMA will inform clinicians, patients and guideline developers the best available evidence on comparative effects benefits of antithrombotic agents after CABG while considering the side effect profile to support future clinical decision-making. We will disseminate the results of our systematic review and NMA through a peer-reviewed journal. PROSPERO REGISTRATION NUMBER: CRD42017065678.

Use of fragmented QRS in prognosticating clinical deterioration and mortality in pulmonary embolism: A meta-analysis.

BACKGROUND: Fragmented QRS (fQRS) on electrocardiography is potentially valuable in prognosticating acute pulmonary embolism (PE). ECG is one of the first tests performed in the emergency department, quickly interpretable, noninvasive, inexpensive, and available in remote areas. We aimed to review fQRS's role in PE prognostication. METHODS: We searched MEDLINE, EMBASE, Google Scholar, Web of Science, abstracts, conference proceedings, and reference lists until October 2017. Eligible studies used fQRS to prognosticate patients for the main outcomes of death and clinical deterioration or escalation of therapy. Two authors independently selected studies, with disagreement resolved by consensus. Ad hoc piloted forms were used to extract data and assess risk of bias. We used a random-effects model to pool relevant data in meta-analysis with odds ratios (OR) and 95% confidence intervals (CI), while all other data were synthesized qualitatively. Statistical heterogeneity was assessed using the I2 index. RESULTS: We included five studies (1,165 patients). There was complete agreement in study selection. fQRS significantly predicted in-hospital mortality (OR [95% CI], 2.92 [1.73-4.91]; p < .001), cardiogenic shock (OR [95% CI], 4.71 [1.61-13.70]; p = .005), and total mortality at 2-year follow-up (OR [95% CI], 4.42 [2.57-7.60]; p < .001). Adjusted analyses were generally consistent with these results. CONCLUSION: Although few studies have explored the current study's question, they showed that fQRS is potentially valuable in PE prognostication. fQRS should be considered as an entry, along with other clinical and ECG findings, in a PE risk score.

Lower Extremity Arterial Calcification on Preoperative Knee Radiographs as a Predictor of Postoperative Cardiovascular Events After Primary Total Knee Arthroplasty.

BACKGROUND: A cross-sectional study of total knee arthroplasty (TKA) patients was conducted to determine the association of lower-extremity arterial calcification (LEAC) with acute perioperative cardiovascular events (CVEs). METHODS: Regression modeling was used to examine the association of radiographic presence of LEAC and acute myocardial infarction (MI), perioperative CVE, 30-day CVE readmit, and 30-day and 1-year mortality. RESULTS: Of 900 TKA patients, LEAC was identified in 21.1%. Of LEAC cases, 1.6% had an acute MI vs 0.1% of non-LEAC cases (P = .031). Perioperative CVE rate was 5.8% for LEAC vs 1.5% for non-LEAC (P = .002). Having LEAC was identified as a significant risk factor for a perioperative CVE (odds ratio [OR] 2.83; 95% confidence interval [CI] 1.09-7.35). Because of limited number of acute MI events, absence of 30-day CVE readmit, 30-day mortality, and few 1-year mortality events, computing OR for these was not possible. Likewise, because of small number of events (n = 3), estimates for the odds of LEAC cases having an acute MI are less reliable, yielding extremely large random errors (OR 11.37; 95% CI 0.09-597.93) and must be interpreted with caution. The OR for 1-year mortality was 1.88 (95% CI 0.17-13.20), but again with large random errors. CONCLUSION: Our study shows that LEAC around the knee is associated with an increased risk of having a perioperative CVE. Crude radiographic detection of LEAC around the knee has the potential to improve risk stratification for TKA patients by informing the surgeon of the need for further preoperative cardiac workup.

The value of electrocardiography in prognosticating clinical deterioration and mortality in acute pulmonary embolism: A systematic review and meta-analysis.

The role of electrocardiography (ECG) in prognosticating pulmonary embolism (PE) is increasingly recognized. ECG is quickly interpretable, noninvasive, inexpensive, and available in remote areas. We hypothesized that ECG can provide useful information about PE prognostication. We searched MEDLINE, EMBASE, Google Scholar, Web of Science, abstracts, conference proceedings, and reference lists through February 2017. Eligible studies used ECG to prognosticate for the main outcomes of death and clinical deterioration or escalation of therapy. Two authors independently selected studies; disagreement was resolved by consensus. Ad hoc piloted forms were used to extract data and assess risk of bias. We used a random-effects model to pool relevant data in meta-analysis with odds ratios (ORs) and 95% confidence intervals (CIs); all other data were synthesized qualitatively. Statistical heterogeneity was assessed using the I 2 value. We included 39 studies (9198 patients) in the systematic review. There was agreement in study selection (κ: 0.91, 95% CI: 0.86-0.96). Most studies were retrospective; some did not appropriately control for confounders. ECG signs that were good predictors of a negative outcome included S1Q3T3 (OR: 3.38, 95% CI: 2.46-4.66, P < 0.001), complete right bundle branch block (OR: 3.90, 95% CI: 2.46-6.20, P < 0.001), T-wave inversion (OR: 1.62, 95% CI: 1.19-2.21, P = 0.002), right axis deviation (OR: 3.24, 95% CI: 1.86-5.64, P < 0.001), and atrial fibrillation (OR: 1.96, 95% CI: 1.45-2.67, P < 0.001) for in-hospital mortality. Several ischemic patterns also were significantly predictive. Our conclusion is that ECG is potentially valuable in prognostication of acute PE.

Comparative effectiveness of transitional care services in patients discharged from the hospital with heart failure: a systematic review and network meta-analysis.

AIMS: To compare the effectiveness of transitional care services in decreasing all-cause death and all-cause readmissions following hospitalization for heart failure (HF). METHODS AND RESULTS: We searched PubMed, Embase, CINAHL, and Cochrane Clinical Trials Register for randomized controlled trials (RCTs) published in 2000-2015 that tested the efficacy of transitional care services in patients hospitalized for HF, provided ≥1 month of follow-up, and reported all-cause mortality or all-cause readmissions. Our network meta-analysis included 53 RCTs (12 356 patients). Among services that significantly decreased all-cause mortality compared with usual care, nurse home visits were most effective [ranking P-score 0.6794; relative risk (RR) 0.78, 95% confidence intervals (CI) 0.62-0.98], followed by disease management clinics (DMCs) (ranking P-score 0.6368; RR 0.80, 95% CI 0.67-0.97). Among services that significantly decreased all-cause readmission, nurse home visits were most effective [ranking P-score 0.8365; incident rate ratio (IRR) 0.65, 95% CI 0.49-0.86], followed by nurse case management (NCM) (ranking P-score 0.6168; IRR 0.77, 95% CI 0.63-0.95), and DMCs (ranking P-score 0.5691; IRR 0.80, 95% CI 0.66-0.97). There was no significant difference in the comparative effectiveness of services that improved each outcome. Nurse home visits had the greatest pooled cost-savings (3810 USD, 95% CI 3682-3937), followed by NCM (3435 USD, 95% CI 3224-3645), and DMCs (245 USD, 95% CI -70 to 559). Telephone, telemonitoring, pharmacist, and education interventions did not significantly improve clinical outcomes. CONCLUSION: Nurse home visits and DMCs decrease all-cause mortality after hospitalization for HF. Along with NCM, they also reduce all-cause readmissions, with no significant difference in comparative effectiveness. These services reduce healthcare system costs to varying degrees.

Investigating the key indicators for evaluating post-disaster shelter.

This study sought to identify the primary indicators for evaluating shelter assistance following natural disasters and then to develop a shelter evaluation instrument based on these indicators. Electronic databases and the 'grey' literature were scoured for publications with a relation to post-disaster shelter assistance. Indicators for evaluating such assistance were extracted from these publications. In total, 1,525 indicators were extracted from 181 publications. A preliminary evaluation instrument was designed from these 1,525 indicators. Shelter experts checked the instrument for face and content validity, and it was revised subsequently based on their input. The revised instrument comprises a version for use by shelter agencies (48 questions that assess 23 indicators) and a version for use by beneficiaries (52 questions that assess 22 indicators). The instrument can serve as a standardised tool to enable groups to gauge whether or not the shelter assistance that they supply meets the needs of disaster-affected populations.

Preoperative Predictors of Pain Catastrophizing, Anxiety, and Depression in Patients Undergoing Total Joint Arthroplasty.

BACKGROUND: The relationship between pain catastrophizing and emotional disorders including anxiety and depression in osteoarthritic patients undergoing total joint arthroplasty (TJA) is an emerging area of study. The purpose of this study was to examine the association of these factors with preoperative patient characteristics. METHODS: A prospective cohort study of preoperative TJA patients using the Pain Catastrophizing Scale (PCS) and Hospital Anxiety and Depression Scale (HADS-A/HADS-D) was conducted. Preoperative measures included visual analog pain scale (VAS), Harris Hip and Knee Society scores, Oxford Score, and Kellgren-Lawrence grade. Logistic and quantile regression were used to assess the relationship between preoperative characteristics and PCS or HADS, adjusting for covariate effects. RESULTS: We recruited 463 TJA patients. VAS pain (odds ratio [OR] 1.23; 95% confidence interval [CI] 1.04-1.45) and Oxford (OR 1.13; 95% CI 1.07-1.20) were significant predictors for PCS and its subdomains excluding rumination. Oxford was the only significant predictor for abnormal HADS-A (OR 1.10; 95% CI 1.04-1.17). VAS pain (OR 1.27; 95% CI 1.02-1.52) and Oxford (OR 1.09; 95% CI 1.01-1.17) were significant predictors for abnormal HADS-D. The quantile regression showed similar patterns of association, with female gender, younger age, and higher ASA also associated with HADS-A. CONCLUSION: The most important predictor of catastrophizing, anxiety and/or depression in TJA patients is preoperative pain and poor subjective function. At-risk patients include those with increased pain and generally good clinical function, as well as younger women with significant comorbidities. Such patients should be identified and targeted psychological therapy implemented preoperatively to optimize coping strategies and adaptive behavior to mitigate potential for inferior TJA outcomes including pain and patient dissatisfaction.

Diagnostic accuracy of skin-prick testing for allergic rhinitis: a systematic review and meta-analysis.

BACKGROUND: Allergic rhinitis is the most common form of allergy worldwide. The accuracy of skin testing for allergic rhinitis is still debated. Our primary objective was to evaluate the diagnostic accuracy of skin-prick testing for allergic rhinitis using the nasal provocation as the reference standard. We also evaluated the diagnostic accuracy of intradermal testing as a secondary objective. METHODS: We searched EBM Reviews from 2005 to March 2015; Embase from 1980 to March 2015; and Ovid MEDLINE(R) from 1946 to until March 2015. We included any study with at least 10 subjects including children. We excluded non-English studies. We performed data extraction and quality assessment using the QUADAS-2 tool. RESULTS: We meta-analysed seven studies assessing the accuracy of skin-prick testing using the bivariate random-effects model, including a total of 430 patients. The pooled estimate for sensitivity and specificity for skin-prick testing was 85 and 77 % respectively. We did not pool results for intradermal testing due to few number of studies (n = 4), each with very small sample size. Of these, two evaluated the accuracy of intradermal testing in confirming skin-prick testing results, with sensitivity ranging from 27 to 50 % and specificity ranging from 60 to 100 %. The other two evaluated the accuracy of intradermal testing as a stand-alone test for diagnosing allergic rhinitis with sensitivity ranging from 60 to 79 % and specificity ranging from 68 to 69 %. CONCLUSIONS: Findings from this review suggest that skin-prick testing is accurate in discriminating subjects with or without allergic rhinitis.

Transportability in Network Meta-analysis.

Network meta-analysis is an extension of the conventional pair wise meta-analysis to include treatments that have not been compared head to head. It has in recent years caught the interest of clinical investigators in comparative effectiveness research. While allowing a simultaneous comparison of a large number of treatment effects, an inclusion of indirect effects (i.e., estimating effects using treatments that have not been randomized head to head) may introduce bias. This bias occurs from not accounting for covariates differences in the analysis, in a way that allows transfer of causal information across trials. Although this problem might not be entirely new to network meta-analysis researchers, it has not been given a formal treatment. Occasionally it is tackled by fitting a meta-regression model to account for imbalance of covariates. However, this approach may still produce biased estimates if covariates responsible for disparity across studies are post-treatment variables. To address the problem, we use the graphical method known as transportability to demonstrate whether and how indirect treatment effects can validly be estimated in network meta-analysis.

Micro-economic impact of congenital heart surgery: results of a prospective study from a limited-resource setting.

INTRODUCTION: The microeconomic impact of surgery for congenital heart disease is unexplored, particularly in resource limited environments. We sought to understand the direct and indirect costs related to congenital heart surgery and its impact on Indian households from a family perspective. METHODS: Baseline and first follow-up data of 644 consecutive children admitted for surgery for congenital heart disease (March 2013 - July 2014) in a tertiary referral hospital in Central Kerala, South India was collected prospectivelyfrom parents through questionnaires using a semi-structured interview schedule. RESULTS: The median age was 8.2 months (IQR: 3.0- 36.0 months). Most families belonged to upper middle (43.0%) and lower middle (35.7%) socioeconomic class. Only 3.9% of families had some form of health insurance. The median expense for the admission and surgery was INR 201898 (IQR: 163287-266139) [I$ 11989 (IQR: 9696-15804)], which was 0.93 (IQR: 0.52-1.49) times the annual family income of affected patients. Median loss of man-days was 35 (IQR: 24-50) and job-days was 15 (IQR: 11-24). Surgical risk category and hospital stay duration significantly predicted higher costs. One in two families reported overwhelming to high financial stress during admission period for surgery. Approximately half of the families borrowed money during the follow up period after surgery. CONCLUSION: Surgery for congenital heart disease results in significant financial burden for majority of families studied. Efforts should be directed at further reductions in treatment costs without compromising the quality of care together with generating financial support for affected families.

Efficacy of Hospital at Home in Patients with Heart Failure: A Systematic Review and Meta-Analysis.

BACKGROUND: Heart failure (HF) is the commonest cause of hospitalization in older adults. Compared to routine hospitalization (RH), hospital at home (HaH)--substitutive hospital-level care in the patient's home--improves outcomes and reduces costs in patients with general medical conditions. The efficacy of HaH in HF is unknown. METHODS AND RESULTS: We searched MEDLINE, Embase, CINAHL, and CENTRAL, for publications from January 1990 to October 2014. We included prospective studies comparing substitutive models of hospitalization to RH in HF. At least 2 reviewers independently selected studies, abstracted data, and assessed quality. We meta-analyzed results from 3 RCTs (n = 203) and narratively synthesized results from 3 observational studies (n = 329). Study quality was modest. In RCTs, HaH increased time to first readmission (mean difference (MD) 14.13 days [95% CI 10.36 to 17.91]), and improved health-related quality of life (HrQOL) at both, 6 months (standardized MD (SMD) -0.31 [-0.45 to -0.18]) and 12 months (SMD -0.17 [-0.31 to -0.02]). In RCTs, HaH demonstrated a trend to decreased readmissions (risk ratio (RR) 0.68 [0.42 to 1.09]), and had no effect on all-cause mortality (RR 0.94 [0.67 to 1.32]). HaH decreased costs of index hospitalization in all RCTs. HaH reduced readmissions and emergency department visits per patient in all 3 observational studies. CONCLUSIONS: In the context of a limited number of modest-quality studies, HaH appears to increase time to readmission, reduce index costs, and improve HrQOL among patients requiring hospital-level care for HF. Larger RCTs are necessary to assess the effect of HaH on readmissions, mortality, and long-term costs.

Not all total joint replacement patients are created equal: preoperative factors and length of stay in hospital.

BACKGROUND: We conducted a cross-sectional study of primary total joint replacement (TJR) patients to determine predictors for prolonged length of stay (LOS) in hospital to identify patient characteristics that may inform resource allocation, accounting for patient complexity. METHODS: Preoperative demographics, medical comorbidities and acute hospital LOS from a consecutive series of primary TJR patients from an academic arthroplasty centre were abstracted. We categorized patients as LOS of 3 or fewer days, 4 days, or 5 or more days to align results with varying LOS benchmarks. To identify predictors for LOS, we used a generalized logistic regression model fitted on an LOS ternary outcome, using LOS of 3 or fewer days as a reference category. RESULTS: The sample included 1459 patients: 61.7% total knee and 38.3% total hip. Male sex was predictive of an LOS of 3 or fewer days (4 d: odds ratio [OR] 0.48, 95% confidence interval [CI] 0.364-0.631; ≥ 5 d: OR 0.57, 95% CI 0.435-0.758), as was current smoking status (4 d: OR 0.425, 95% CI 0.274-0.659; ≥ 5 d: OR 0.489, 95% CI 0.314-0.762). Strong predictors of prolonged LOS included total hip versus total knee arthroplasty, age 75 years or older, American Society of Anesthesiologists classification of 3 and 4 and number of cardiovascular comorbidities. CONCLUSION: Not all patients undergoing TJR are equal. The goal should be individual patient-focused care rather than a predetermined LOS that is not achievable for all patients. Hospital resource planning must account for patient complexity when planning future bed management.

CONTEXTE: Nous avons réalisé une étude transversale auprès de patients soumis à une chirurgie pour prothèse articulaire totale (PAT) afin de déterminer les facteurs prédictifs d'une durée du séjour hospitalier (DSH) prolongée (en établissement de soins de courte durée) et de dégager les caractéristiques des patients qui permettraient d'orienter l'allocation des ressources en tenant compte de la complexité des cas. MÉTHODES: Nous avons extrait les données démographiques préopératoires, les comorbidités médicales et la DSH pour une série de cas consécutifs de PAT primaire dans un centre d'arthroplastie universitaire. Nous avons classé les patients par catégorie de DSH, soit 3 jours ou moins, 4 jours, ou 5 jours et plus, de manière à répartir les résultats selon les diverses cibles de DSH. Pour dégager les facteurs prédictifs de la DSH, nous avons utilisé un modèle de régression logistique généralisé intégré à un paramètre ternaire de DSH, en utilisant la DSH de 3 jours ou moins comme catégorie de référence. RÉSULTANTS: L'échantillon regroupait 1459 patients : 61,7 % recevant une prothèse totale du genou (PTG) et 38,3 % recevant une prothèse totale de la hanche (PTH). Le fait d'être de sexe masculin était prédictif d'une DSH de 3 jours ou moins (4 j : rapport des cotes [RC] 0,48, intervalle de confiance [IC] à 95 % 0,364­0,631; ≥ 5 j : RC 0,57, IC à 95 % 0,435­0,758), tout comme le statut à l'égard du tabagisme (4 j : RC 0,425, IC à 95 % 0,274­0,659; ≥ 5 j : RC 0,489, IC à 95 % 0,314­0,762). Les facteurs prédictifs fiables d'une DSH prolongée incluaient la PTH c. PTG, l'âge de 75 ans ou plus, une classification de 3 ou 4 selon l'American Society of Anesthesiologists et le nombre de comorbidités cardiovasculaires. CONCLUSION: Les patients soumis à une PAT ne s'équivalent pas tous. L'objectif devrait être d'administrer des soins centrés sur le patient plutôt que sur une DSH prédéterminée qui, dans les faits, ne s'applique pas à tous patients. La planification des ressources hospitalières devra à l'avenir tenir compte de la complexité des cas dans la planification de la gestion des lits.
