Development and Psychometric Evaluation of the Pre-hospital Medical Emergencies Early Warning Scale.

INTRODUCTION: The number of requests for emergency medical services (EMSs) has increased during the past decade. However, most of the transports are not essential. Therefore, it seems crucial to develop an instrument to help EMS staff accurately identify patients who need pre-hospital care and transportation. The aim of this study was to develop and evaluate the psychometric properties of the Pre-hospital Medical Emergencies Early Warning Scale (Pre-MEWS). MATERIALS AND METHODS: This mixed-method study was conducted in two phases. In the first phase, a qualitative content analysis study was conducted to identify the predictors of medical patients' need for pre-hospital EMS and transportation. In the second phase, the face and the content validity as well as the internal consistency of the scale were evaluated. Finally, the items of the scale were scored and scoring system was presented. RESULTS: The final version of the scale contained 22 items and its total score ranged from 0 to 54. CONCLUSIONS: Pre-MEWS helps EMS staffs properly understand medical patients' conditions in pre-hospital environments and accurately identify their need for EMS and transportation.

The Effectiveness of Mobile Phone Text Messaging in Improving Medication Adherence for Patients with Chronic Diseases: A Systematic Review.

CONTEXT: Medication non-adherence is a commonly observed problem in the self-administration of treatment, regardless of the disease type. Text messaging reminders, as electronic reminders, provide an opportunity to improve medication adherence. In this study, we aimed to provide evidence addressing the question of whether text message reminders were effective in improving patients' adherence to medication. EVIDENCE ACQUISITION: We carried out a systematic literature search, using the five electronic bibliographic databases: PubMed, Embase, PsycINFO, CINAHL, and the Cochrane central register of controlled trials. Studies were included on the basis of whether they examined the benefits and effects of short-message service (SMS) interventions on medication adherence. RESULTS: The results of this systematic review indicated that text messaging interventions have improved patients' medication adherence rate (85%, 29.34). Included in the review, those who had problems with adherence, or those whom text messaging was most helpful had HIV, asthma, diabetes, schizophrenia and heart disease (73.5%). The period of intervention varied from 1 week to 14 months. The most common study design was randomized controlled trials (RCTs) (66%) carried out in the developed countries. CONCLUSIONS: This study demonstrated the potential of mobile phone text messaging for medication non-adherence problem solving.

A warning threshold for monitoring tuberculosis surveillance data: an alternative to hidden Markov model.

OBJECTIVES: Although hidden Markov model (HMM) is known as a powerful tool for the detection of epidemics based on the historical data, the frequent use of such a model poses some limitation especially when decision-making is required for new observations. This study was aimed to address a warning threshold for monitoring the weekly incidences of tuberculosis as an alternative to HMM. METHODS: We extracted the weekly counts of newly diagnosed patients with sputum smear-positive pulmonary TB from 2005 to 2011 nationwide. To detect unexpected incidences of the disease, two approaches: Serfling and HMM, were applied in presence/absence of linear, seasonal and autoregressive components. Models were subsequently evaluated in terms of goodness of fit, and their results were compared in detection of the disease phases. Then, multiple hypothetical thresholds were constructed based on the estimate of models and the optimal one was revealed through ROC curve analysis. RESULTS: Findings from both adjusted R-square (R~2) and Bayesian information criterion (BIC) presented a higher goodness of fit for periodic autoregressive HMM (BIC = -1323.6; R~2=0.74) than other models. According to ROC analysis, better values for both Youden's index and area under curve (0. 96 and 0. 98 respectively) were obtained by the threshold based on the estimate of periodic autoregressive model. CONCLUSIONS: As the optimal threshold presented in this study is simple in concept and has no limitation in practice, especially for monitoring new observations, we would recommend such a threshold to be used for monitoring of TB incidence data in the surveillance system.

Are Iranian obese women candidate for bariatric surgery different cognitively, emotionally and behaviorally from their normal weight counterparts?

OBJECTIVE: The purpose of the present study was to examine the cognitive, emotional and behavioral differences between obese and normal weight women. METHODS: The participants consisted of 60 obese women (BMI ≥ 35, Mean age 35.83) who were candidates for bariatric surgery and 60 normal weight women (BMI ≤ 24.90, Mean age 33.38) who were selected through convenient sampling method. The two groups were matched with respect to age and education. Measures included the Young Schema Questionnaire-Short Form, Difficulties in Emotion Regulation Scale (DERS) and the Binge Eating Scale. Independent sample t test and Mann-Whitney U tests were conducted to compare the two groups' scores on early maladaptive schemas, DER and binge eating. RESULTS: Results indicated that obese women candidate for bariatric surgery scored significantly higher on emotional deprivation, mistrust, failure, dependency, enmeshment, self-sacrifice, especially abandonment, social isolation, vulnerability, self-control and subjugation schemas, but not on shame, entitlement, emotional inhibition and unrelenting standards. Obese women also displayed higher scores on three subscales of DERS, i.e., goal, impulse and strategies. BE scores were significantly higher in obese women than normal weight ones. CONCLUSION: The findings showed that obese women candidates for bariatric surgery suffered from more cognitive, emotional and behavioral vulnerability compared to women with normal weight. Addressing these vulnerabilities among obese women could improve outcomes of weight loss surgeries and cognitive behavioral interventions so that weight regain is minimized and better outcomes are achieved.

Physiological-social scores in predicting outcomes of prehospital internal patients.

The physiological-social modified early warning score system is a newly developed instrument for the identification of patients at risk. The aim of this study was to investigate the feasibility of using the physiological-social modified early warning score system for the identification of patients that needed prehospital emergency care. This prospective cohort study was conducted with 2157 patients. This instrument was used as a measure to detect critical illness in patients hospitalised in internal wards. Judgment by an emergency medicine specialist was used as a measure of standard. Data were analyzed by using receiver operating characteristics curves and the area under the curve with 95% confidence interval. The mean score of the physiological-social modified early warning score system was 2.71 ± 3.55. Moreover, 97.6% patients with the score ≥ 4 needed prehospital emergency services. The area under receiver operating characteristic curve was 0.738 (95% CI = 0.708-0.767). Emergency medical staffs can use PMEWS ≥ 4 to identify those patients hospitalised in the internal ward as at risk patients. The physiological-social modified early warning score system is suggested to be used for decision-making of emergency staff about internal patients' wards in EMS situations.

Exploring Factors Affecting Emergency Medical Services Staffs' Decision about Transporting Medical Patients to Medical Facilities.

Transfer of patients in medical emergency situations is one of the most important missions of emergency medical service (EMS) staffs. So this study was performed to explore affecting factors in EMS staffs' decision during transporting of patients in medical situations to medical facilities. The participants in this qualitative study consisted of 18 EMS staffs working in prehospital care facilities in Tehran, Iran. Data were gathered through semistructured interviews. The data were analyzed using a content analysis approach. The data analysis revealed the following theme: "degree of perceived risk in EMS staffs and their patients." This theme consisted of two main categories: (1) patient's condition' and (2) the context of the EMS mission'. The patent's condition category emerged from "physical health statuses," "socioeconomic statuses," and "cultural background" subcategories. The context of the EMS mission also emerged from two subcategories of "characteristics of the mission" and EMS staffs characteristics'. EMS system managers can consider adequate technical, informational, financial, educational, and emotional supports to facilitate the decision making of their staffs. Also, development of an effective and user-friendly checklist and scoring system was recommended for quick and easy recognition of patients' needs for transportation in a prehospital situation.

Effectiveness of jaw relaxation for burn dressing pain: randomized clinical trial.

Patients hospitalized for burn injuries experience severe pain, both immediately after the injury and during daily therapeutic procedures such as dressing changes. Relaxation is increasingly suggested as a pain control technique that can be used by nurses in daily practice. Yet the effects of relaxation on burn pain are not clear. The aim of this study was to investigate whether jaw relaxation will decrease pain intensity of burn dressing. Accordingly, a randomized clinical trial (n = 100) was conducted between 2009 and 2010 to compare jaw relaxation and usual care. Consenting patients were randomly assigned to either experimental or control groups using minimization. The experimental group practiced jaw relaxation for 20 minutes before entering the dressing room. Data were collected by visual analog scale (VAS), and several structured questions were asked of the experimental group. No significant difference was seen between mean pain intensity scores in the experimental and control groups after dressing (p = .676). Regarding the ineffectiveness of jaw relaxation for pain intensity of burn dressing, future studies are suggested to concentrate on longer durations of relaxation time and continuing the procedure in dressing room. Simultaneous study of the effect of this technique on residual, breakthrough, and procedural burn pain is also recommended.

The effect of jaw relaxation on pain anxiety during burn dressings: randomised clinical trial.

AIM: The purpose of this randomised clinical trial (RCT) was to determine the effect of jaw relaxation on pain anxiety related to dressing changes in burn injuries. INTRODUCTION: Patients hospitalised with burns experience high levels of anticipatory anxiety during dressing changes, which cannot be completely managed by anxiolytic drugs. Nurses as members of the burn care team contribute to pain management by using relaxation techniques as one of the most frequently used approaches to pain anxiety management. However, there is not enough information about the effects of these techniques on pain anxiety of patients with burns. The aim of this study was to determine the effect of jaw relaxation on pain anxiety related to dressing changes in burn injuries. METHODS: It was a randomised clinical trial with a control group. A total of 100 patients hospitalised in Shahid Motahari Burn Centre affiliated with Tehran University of Medical Sciences were recruited by convenience sampling and were randomly assigned to either experimental or control groups using minimisation. With institutional approval and written consent, the experimental group practiced jaw relaxation for 20 min before entering the dressing room. Data were collected by the Burn Specific Pain Anxiety Scale (BSPAS) during July-December 2009 and analysed using Statistical Package for the Social Sciences (SPSS)-PC (17). RESULTS: An independent t-test showed no significant difference between mean pain anxiety scores in the experimental and control group before intervention (p=0.787). A dependent t-test showed significantly less pain anxiety after intervention (before dressing) in the experimental group (p<0.05). Moreover, the independent t-test showed that the post-dressing pain anxiety of the experimental group was less than the control group (p<0.05). However, the dependent t-test showed no significant difference between before and after dressing pain anxiety (after intervention) in the experimental group (p=0.303). CONCLUSION: Nurses can independently decrease the pain anxiety of patients with burns and its subsequent physical and psychological burden by teaching the simple and inexpensive technique of jaw relaxation. Further research is needed to study the effect of this technique on pain anxiety of patients suffering from other painful procedures.
