RESUMEN
BACKGROUND: The current study aimed to measure and decompose socioeconomic-related inequalities in DMFT (decayed, missing, and filled teeth) index among adults in Iran. METHODS: The study data were extracted from the adult component of Prospective Epidemiological Research Studies in IrAN (PERSIAN) from 17 centers in 14 different provinces of Iran. DMFT score was used as a measure of dental caries among adults in Iran. The concentration curve and relative concentration index (RC) was used to quantify and decompose socioeconomic-related inequalities in DMFT. RESULTS: A total of 128,813 adults aged 35 and older were included in the study. The mean (Standard Deviation [SD]) score of D, M, F and DMFT of the adults was 3.3 (4.6), 12.6 (10.5), 2.1 (3.4) and 18.0 (9.5), respectively. The findings suggested that DMFT was mainly concentrated among the socioeconomically disadvantaged adults (RC = - 0.064; 95% confidence interval [CI), - 0.066 to - 0.063). Socioeconomic status, being male, older age and being a widow or divorced were identified as the main factors contributing to the concentration of DMFT among the worse-off adults. CONCLUSIONS: It is recommended to focus on the dental caries status of socioeconomically disadvantaged groups in order to reduce socioeconomic-related inequality in oral health among Iranian adults. Reducing socioeconomic-related inequalities in dental caries should be accompanied by appropriate health promotion policies that focus actions on the fundamental socioeconomic causes of dental disease.
RESUMEN
PURPOSE: To assess the extent to which clinical rules (CRs) can be implemented for automatic evaluation of quality of care in general practice. METHODS: We assessed 81 clinical rules (CRs) adapted from a subset of Assessing Care of Vulnerable Elders (ACOVE) clinical rules, against Dutch College of General Practitioners (NHG) data model. Each CR was analyzed using the Logical Elements Rule METHOD: (LERM). LERM is a stepwise method of assessing and formalizing clinical rules for decision support. Clinical rules that satisfied the criteria outlined in the LERM method were judged to be implementable in automatic evaluation in general practice. RESULTS: Thirty-three out of 81 (40.7%) Dutch-translated ACOVE clinical rules can be automatically evaluated in electronic medical record systems. Seven out of 7 CRs (100%) in the domain of diabetes can be automatically evaluated, 9/17 (52.9%) in medication use, 5/10 (50%) in depression care, 3/6 (50%) in nutrition care, 6/13 (46.1%) in dementia care, 1/6 (16.6%) in end of life care, 2/13 (15.3%) in continuity of care, and 0/9 (0%) in the fall-related care. Lack of documentation of care activities between primary and secondary health facilities and ambiguous formulation of clinical rules were the main reasons for the inability to automate the clinical rules. CONCLUSION: Approximately two-fifths of the primary care Dutch ACOVE-based clinical rules can be automatically evaluated. Clear definition of clinical rules, improved GP database design and electronic linkage of primary and secondary healthcare facilities can improve prospects of automatic assessment of quality of care. These findings are relevant especially because the Netherlands has very high automation of primary care.

BACKGROUND: Metabolic syndrome is defined by insulin resistance and a clustering of other cardiovascular risk factors. Crocin is a carotenoid derived from the stigmas of the saffron flower and had previously been shown to affect lipid profile. However, the mechanism for this function is not well understood. The present trial aimed to investigate the possible effect of crocin on plasma levels of cholesteryl ester transfer protein and lipid profile in individuals with metabolic syndrome. METHODS: This was a randomized, double-blind, placebo-controlled, clinical trial consisting of an 8-week treatment with crocin, or placebo tablets between April and June 2014, in the Nutrition Clinic of Ghaem Teaching Hospital, Mashhad, Iran. Participants were randomly assigned to take a 30 mg/day crocin (n = 22) in the intervention group or placebo (n = 22) in the control group. Anthropometric, hematological and biochemical parameters were measured and recorded during pre and post-treatment periods. RESULTS: Whilst plasma cholesteryl ester transfer protein was increased in the group taking the crocin tablet by 27.81% during the trial period (P = 0.013), the difference between the crocin and placebo groups was not significant (P = 0.116). Moreover, the percent changes in cholesterol (P = 0.702), triglyceride (P = 0.080), low-density lipoprotein (LDL) (P = 0.986), high-density lipoprotein (HDL) (P = 0.687) and fasting blood glucose (P = 0.614) did not differ significantly between intervention and control groups. CONCLUSION: Although crocin supplements increased the serum cholesteryl ester transfer protein in patients with metabolic syndrome, this change was not significant between treatment and placebo groups.
RESUMEN
The metabolic syndrome (MetS) is associated with a pro-inflammatory milieu that may partially account for its association with an increased cardiovascular risk. We aimed to (1) evaluate the serum concentrations of twelve cytokines and growth factors (epidermal growth factor (EGF), interferon-γ (IFN-γ), IL-1α/-1ß/-2/-4/-6/-8/-10, monocyte chemoattractant protein-1 (MCP-1), TNF-α and vascular endothelial growth factor (VEGF)) in 303 individuals with or without the MetS; and (2) explore their relationship with the presence of the MetS. Patients with the MetS had significantly higher serum concentrations of IFN-γ, EGF, IL-1α/-1ß/-2/-4/-6/-8/-10, MCP-1 and TNF-α, whilst serum VEGF concentrations were markedly lower compared with the control group (e.g. 38·55 v. 82·18 pg/ml; P< 0·05). Amongst these parameters, IFN-γ and IL-1α emerged as the most significant independent predictors of the MetS. In conclusion, our findings demonstrate that patients with the MetS had an altered blood cytokine and growth factor profile that may partially account for its adverse clinical outcomes. Further prospective studies in larger multi-centre settings are required to unravel the role and association of the emerging biomarkers with the MetS and their implication in therapeutic intervention.

Hypertension is an important risk factor for cardiovascular disease and there is increasing evidence that inflammation and abnormal immune responses are involved in the pathogenesis of hypertension. However, the data on the association between specific cytokine concentrations and hypertension are inconsistent. We have evaluated the association between 12 cytokines/growth factors and the presence of different degrees of hypertension, comparing these concentrations to values in a healthy group of subjects. The concentrations of interleukin (IL)-1α, -1ß, -2, -4, -6, -8, -10, tumor necrosis factor (TNF-α), interferon-γ (IFN-γ), monocyte chemoattractant protein (MCP-1), epidermal growth factor, and vascular endothelial growth factor were measured in 155 hypertensive patients and 148 healthy subjects, using EV-3513 cytokine biochip arrays, a competitive chemiluminescence immunoassay. Univariate and multivariate analyses were used to evaluate the association of specific cytokines and growth factors with systolic blood pressure (SBP) and diastolic blood pressure (DBP). Hypertensive subjects had higher serum concentrations of IL-1α, -2, -8, vascular endothelial growth factor, IFN-γ, TNF-α, MCP-1, and epidermal growth factor; and lower concentrations of anti-inflammatory cytokine, IL-10 (P < .05), compared with the healthy individuals. The serum concentrations of IL-4, -6, and -1ß did not differ between the hypertensive subjects and control group. Univariate and multivariate analyses revealed that IL-1α and IFN-γ were independent predictors of a high SBP, while IFN-γ, IL-1α, TNF-α, and MCP-1 remained statistically significant for DBP after correction for age, gender, Body mass index, smoking, fasting blood glucose, and triglycerides. There was a significant association between the concentrations of several cytokines and hypertension. These associations may either be related to common underlying factors that cause hypertension and may also be proinflammatory or because these inflammatory cytokines might directly be involved in the etiology of hypertension.

Falls form a major health problem for older persons, and increasingly strain the healthcare system. The Internet is a potentially useful platform for empowering seniors. The aim of this study was therefore to investigate the information-seeking behavior about falls among elderly Internet users. A web-based survey was distributed among all members of an association of elderly people (> 60 years old). Fallers and non-fallers, seniors with and without experience with information seeking and the willingness of elderly for undertaking self-assessment tests on the Internet versus solely receiving information about falls were compared. In general, there was much stated interest in receiving information about conditions and medications that increase the risk of falls and information on safety in the house. Around half of the 62 respondents did not feel that they are well-informed about falls. Searching for fall-related information was not significantly associated with having falls in the previous 12 months (OR 2.11, CI: 0.55-8.16). The majority expressed higher interest in receiving fall-related information than undertaking a self-assessment test. However, only a small proportion had searched for this information already.

BACKGROUND: Polypharmacy, and specifically the use of multiple fall-risk-increasing drugs (FRID), have been associated with increased risk of falling in older age. However, it is not yet clear whether the known set of FRIDs can be extrapolated to recurrent fallers, since they form a distinct group of more vulnerable older persons with different characteristics. OBJECTIVES: We aim to investigate which classes of medications are associated with recurrent falls in elderly patients visiting the Emergency Department (ED) after a fall. METHODS: This study had a cross-sectional design and was conducted in the ED of an academic medical center. Patients who sustained a fall, 65 years or older, and who visited the ED between 2004 and 2010 were invited to fill in a validated fall questionnaire designed to assess patient and fall characteristics (CAREFALL Triage Instrument [CTI]). We translated self-reported medications to anatomical therapeutic chemical (ATC) codes (at the second level). Univariate logistic regression analysis was performed to explore the association between medication classes and the outcome parameter (recurrent fall). Multivariate logistic regression was used to assess the associations after adjustment to potential confounders. RESULTS: In total 2,258 patients participated in our study, of whom 39 % (873) had sustained two or more falls within the previous year. After adjustment for the potential confounders, drugs for acid-related disorders (adjusted odds ratio [aOR] 1.29; 95 % CI 1.031.60), analgesics (aOR 1.22; 95 % CI 1.061.41), anti-Parkinson drugs (aOR 1.59; 95 % CI 1.022.46), nasal preparations (aOR 1.49; 95 % CI 1.072.08), ophthalmologicals (aOR 1.51; 95 % CI 1.102.09); antipsychotics (aOR 2.21; 95 % CI 1.084.52), and antidepressants (aOR 1.64; 95 % CI 1.132.37) remained statistically significantly associated with an ED visit due to a recurrent fall. CONCLUSIONS: Known FRIDs, such as psychotropic drugs, also increase the risk of recurrent falls. However, we found four relatively new classes that showed significant association with recurrent falls. In part, these classes may act as markers of frailty and comorbidity, or they may reflect differences in the risk factors affecting the older, frailer population that tends to sustain recurrent falls. Further investigation is needed to elucidate causes and ways to prevent recurrent falls.

OBJECTIVES: To propose a combined disease management and process modeling approach for evaluating and improving care processes, and demonstrate its usability and usefulness in a real-world fall management case study. METHODS: We identified essential disease management related concepts and mapped them into explicit questions meant to expose areas for improvement in the respective care processes. We applied the disease management oriented questions to a process model of a comprehensive real world fall prevention and treatment program covering primary and secondary care. We relied on interviews and observations to complete the process models, which were captured in UML activity diagrams. A preliminary evaluation of the usability of our approach by gauging the experience of the modeler and an external validator was conducted, and the usefulness of the method was evaluated by gathering feedback from stakeholders at an invitational conference of 75 attendees. RESULTS: The process model of the fall management program was organized around the clinical tasks of case finding, risk profiling, decision making, coordination and interventions. Applying the disease management questions to the process models exposed weaknesses in the process including: absence of program ownership, under-detection of falls in primary care, and lack of efficient communication among stakeholders due to missing awareness about other stakeholders' workflow. The modelers experienced the approach as usable and the attendees of the invitational conference found the analysis results to be valid. CONCLUSIONS: The proposed disease management view of process modeling was usable and useful for systematically identifying areas of improvement in a fall management program. Although specifically applied to fall management, we believe our case study is characteristic of various disease management settings, suggesting the wider applicability of the approach.

PURPOSE: Drug-drug interactions (DDIs) may compromise patient safety. However, there are no good estimates of their frequency or understanding of their nature in the intensive care unit (ICU). The objective of this study was to determine the frequency and nature of potential DDIs (pDDIs) in the ICU when assessed in light of documented and perceived clinical relevance. METHODS: We developed a computerized algorithm to identify pDDI occurrence in ICU admissions with medication administration, on the basis of the Dutch national drug database. A panel of nine local pharmacists and intensivists completed questionnaires to classify the perceived relevance of the identified pDDI types for the ICU. A focus group discussed the conflicting classifications of relevance to reach consensus. For the pDDI types classified as relevant, we calculated their number and frequency per admission days. RESULTS: Out of 9644 admissions, 3892 had at least one pDDI. The pDDIs corresponded to 85 types, 36 of which were deemed relevant on the basis of the survey and focus group. These 36 types corresponded to 16,122 pDDIs (rate: 33.6 per 100 admission days) and 1084 unique admissions. PDDIs occurred in 11% of admissions to the general ICU, after limiting analysis to severe and relevant DDI types. The most frequently encountered drug classes were antithrombotic agents and antibacterials for systemic use. CONCLUSIONS: There are many potential DDIs with high perceived relevance in the ICU that appear to require attention and follow-up. Computerized decision support may help reduce the number of pDDIs but needs to be tailored to the environment in which it operates.

BACKGROUND: Inappropriate medication prescription is a common cause of preventable adverse drug events among elderly persons in the primary care setting. OBJECTIVE: The aim of this systematic review is to quantify the extent of inappropriate prescription to elderly persons in the primary care setting. METHODS: We systematically searched Ovid-Medline and Ovid-EMBASE from 1950 and 1980 respectively to March 2012. Two independent reviewers screened and selected primary studies published in English that measured (in)appropriate medication prescription among elderly persons (>65 years) in the primary care setting. We extracted data sources, instruments for assessing medication prescription appropriateness, and the rate of inappropriate medication prescriptions. We grouped the reported individual medications according to the Anatomical Therapeutic and Chemical (ATC) classification and compared the median rate of inappropriate medication prescription and its range within each therapeutic class. RESULTS: We included 19 studies, 14 of which used the Beers criteria as the instrument for assessing appropriateness of prescriptions. The median rate of inappropriate medication prescriptions (IMP) was 20.5% [IQR 18.1 to 25.6%.]. Medications with largest median rate of inappropriate medication prescriptions were propoxyphene 4.52 (0.10-23.30)%, doxazosin 3.96 (0.32 15.70)%, diphenhydramine 3.30 (0.02-4.40)% and amitriptiline 3.20 (0.05-20.5)% in a decreasing order of IMP rate. Available studies described unequal sets of medications and different measurement tools to estimate the overall prevalence of inappropriate prescription. CONCLUSIONS: Approximately one in five prescriptions to elderly persons in primary care is inappropropriate despite the attention that has been directed to quality of prescription. Diphenhydramine and amitriptiline are the most common inappropriately prescribed medications with high risk adverse events while propoxyphene and doxazoxin are the most commonly prescribed medications with low risk adverse events. These medications are good candidates for being targeted for improvement e.g. by computerized clinical decision support.

Relevancy of potential drug-drug interactions (pDDIs) is crucial in alerting system design. However, the way this relevancy is perceived is not well understood. The main objective of this study was to gauge and identify differences in perceptions of intensivists and pharmacists about pDDI relevancy in the ICU. Interactions were defined according to the national medication database using a computerized algorithm. Intensivists and pharmacists filled in a questionnaire to score their perceptions on relevancy of encountered pDDIs types. We conducted a focus group session to discuss pDDIs receiving markedly different relevancy scores. The questionnaire addressed 53 pDDI types. Pharmacists rated 29 pDDI types (54.7%) in the broad category "relevant" versus 16 (30.2%) for intensivists (p-value<0.001). The pharmacists and intensivists gave the same scores for 23 pDDI types (12 as relevant, and 11 as not relevant), and scored 30 types differently. The focus group discussion resulted in a total of 36 relevant and 17 not relevant types. Compared to the pharmacists in this panel, the intensivists were less inclined to consider a pDDI type as relevant. It is important to tailor medication databases with information about evidence and severity of pDDIs to the environment in which they are used.

PURPOSE: To identify and uniformly describe studies employing the Assessing Care Of Vulnerable Elders (ACOVE) quality indicators within a comprehensive thematic model that reflects how the indicators were used. DATA SOURCES: A systematic search of MEDLINE, EMBASE and CINAHL was conducted. STUDY SELECTION: English-language studies meeting our criteria published prior to January 2010. Data extraction Included studies were analyzed and described by two independent researchers. RESULTS OF DATA SYNTHESIS: A total of 41 articles met our selection criteria. Studies were classified into the themes 'Application of indicators' (32 studies) and ' ANALYSIS: and development of indicators' (13 studies). 'Application' studies included assessing quality of care, influencing behavior of health professionals and examining the association of quality of care with other factors. 'Analysis and development' included studies developing new indicator sets, and those adapting and validating the original quality indicators to new settings. CONCLUSIONS: The indicators were used in a wide range of applications with two main foci: the assessment of quality of care for elderly patients, and investigating the feasibility of similar indicators and their adaptation to new settings. Very few of the studies published to date have addressed the goal of care improvement. We foresee an important role for application of indicators that proactively help health-care professionals to deliver the right care at the right time, for example by resorting to decision support systems.

BACKGROUND: Care of the elderly is recognized as an increasingly important segment of health care. The Assessing Care Of Vulnerable Elderly (ACOVE) quality indicators (QIs) were developed to assess and improve the care of elderly patients. OBJECTIVES: The purpose of this review is to summarize studies that assess the quality of care using QIs from or based on ACOVE, in order to evaluate the state of quality of care for the reported conditions. METHODS: We systematically searched MEDLINE, EMBASE and CINAHL for English-language studies indexed by February 2010. Articles were included if they used any ACOVE QIs, or adaptations thereof, for assessing the quality of care. Included studies were analyzed and relevant information was extracted. We summarized the results of these studies, and when possible generated an overall conclusion about the quality of care as measured by ACOVE for each condition, in various settings, and for each QI. RESULTS: Seventeen studies were included with 278 QIs (original, adapted or newly developed). The quality scores showed large variation between and within conditions. Only a few conditions showed a stable pass rate range over multiple studies. Overall, pass rates for dementia (interquartile range (IQR): 11%-35%), depression (IQR: 27%-41%), osteoporosis (IQR: 34%-43%) and osteoarthritis (IQR: 29-41%) were notably low. Medication management and use (range: 81%-90%), hearing loss (77%-79%) and continuity of care (76%-80%) scored higher than other conditions. Out of the 278 QIs, 141 (50%) had mean pass rates below 50% and 121 QIs (44%) had pass rates above 50%. Twenty-three percent of the QIs scored above 75%, and 16% scored below 25%. CONCLUSIONS: Quality of care per condition varies markedly across studies. Although there has been much effort in improving the care for elderly patients in the last years, the reported quality of care according to the ACOVE indicators is still relatively low.
