Clinical and electrocardiogram presentations of patients with high serum potassium concentrations within emergency settings: a prospective study.

BACKGROUND: Elevated potassium level is a common and reversible peri-arrest condition. Diagnosis and management of hyperkalemia in a short time is critical, where electrocardiogram (ECG) alterations might be helpful. We aimed to investigate the role of clinical features and ECGs in early diagnosing and treating hyperkalemia. METHODS: Prospectively, adult patients who presented to the emergency department (ED) from July 2019 to March 2020 with hyperkalemia (serum potassium ≥5.5mmol/L) were included. History was obtained, and laboratory investigations and ECGs were performed at the presentation and before initiating hyperkalemia therapy. Hyperkalemia severity was divided into mild (5.5-5.9mmol/L), moderate (6.0-6.4mmol/L), and severe (≥6.5mmol/L). A cardiologist and emergency physician blinded to laboratory values, study design, and patients' diagnoses interpreted ECGs and presenting symptoms independently to predict hyperkalemia. RESULTS: Sixty-seven hyperkalemic patients with a mean (±SD) serum potassium level of 6.5±0.7mmol/L were included in this study. The mean age was 63.9±15.1, and 58.2% were females. Hyperkalemia was mild in 10.4%, moderate in 40.3%, and severe in 49.3%. Almost two thirds of patients (71.6%) had hypertension, 67.2% diabetes, and 64.2% chronic kidney disease. About one-quarter of patients (22.4%) were asymptomatic, while fatigue (46.3%), dyspnea (28.4%), and nausea/vomiting (20.9%) were the most common presenting symptoms. Normal ECGs were observed in 25.4% of patients, while alterations in 74.6%. Atrial fibrillation (13.4%), peaked T wave (11.9%), widened QRS (11.9%), prolonged PR interval (10.5%), and flattening P wave (10.5%) were the most common. Peaked T wave was significantly more common in severe hyperkalemia (87.5%) than in mild and moderate hyperkalemia (12.5%, 0.0%, respectively) (p=0.041). The physicians' sensitivities for predicting hyperkalemia were 35.8% and 28.4%, improved to 51.5% and 42.4%, respectively, when limiting the analyses to severe hyperkalemia. The mean (±SD) time to initial hyperkalemia treatment was 63.8±31.5 min. Potassium levels were positively correlated with PR interval (r=0.283, p=0.038), QRS duration (r=0.361, p=0.003), peaked T wave (r=0.242, p=0.041), and serum levels of creatinine (r=0.347, p=0.004), BUN (r=0.312, p=0.008), and CK (r=0.373, p=0.039). CONCLUSIONS: The physicians' abilities to predict hyperkalemia based on ECG and symptoms were poor. ECG could not be solely relied on, and serum potassium tests should be conducted for accurate diagnosis.

The Impact of Perceived Social Support During Pregnancy on Postpartum Infant-Focused Anxieties: A Prospective Cohort Study of Mothers in Northern Jordan.

OBJECTIVE: This study aimed to evaluate the association between perceived social support during pregnancy and levels of anxiety among postpartum women using an anxiety-specific screening instrument. METHODS: Using a prospective cohort design, a two-stage methodology was conducted to collect data from women seeking maternal care at the King Abdullah University Hospital in northern Jordan. In the first stage, perceived social support was assessed among pregnant women using the Medical Outcomes Study Social Support Survey. During the first six months after childbirth, postpartum women were contacted to complete the second stage, wherein their perceptions of infant-focused anxieties were assessed using the Postpartum Specific Anxiety Scale. In our study, two types of infant-focused anxieties were investigated among a final sample of 419 mothers: infant safety and welfare anxieties and practical infant care anxieties. RESULTS: The results of multivariate linear regression analysis indicated that providing pregnant women with high levels of emotional support from close social networks (ß= -0.08, p= 0.01) and perceiving informational support from health care providers (ß= -0.71, p< 0.01) were protective factors for reducing the levels of postpartum anxiety concerning infant safety and welfare. Our findings also demonstrated that pregnant mothers who perceived high informational support from health care providers had a lower level of postpartum anxiety about practical infant care (ß= -0.20, p< 0.01). In contrast, mothers who reported receiving high tangible support from close social networks during pregnancy had a significantly higher level of perceived anxiety concerning practical infant care after delivery (ß= 0.13, p= 0.02). CONCLUSION: Our study suggests that postpartum anxiety would be reduced if effective informational support were readily available for pregnant women. There is a clear need for building bridges between women, their families, and providers to distinguish the specific type and amount of support that should be provided to mothers during pregnancy.

The Association Between Cognitive Medical Errors and Their Contributing Organizational and Individual Factors.

BACKGROUND: Examining cognitive medical errors (MEs) and their contributing factors is vital in health systems research, as it provides baseline data that can be used to develop appropriate interventions to prevent and/or minimize errors. The primary aim of this study was to investigate the association between cognitive MEs and hospitals' organizational factors and the individual psychological and functional factors. METHODS: This cross-sectional study was conducted in three main hospitals in Northern Jordan. A proportional sampling technique was employed to decide the number of participants from each hospital. Data from physicians and nurses (n=400) were collected using a self-administered questionnaire, which was developed based on pertinent literature review. Exploratory and confirmatory factor analyses were conducted to validate the study instrument. The relationships between the variables were analyzed through structural equation modeling (SEM) using AMOS. Multi-group analysis was also performed to examine the differences in the participants' perceptions towards the respective variables between the three selected hospitals. RESULTS: Our results showed a non-significant negative association between MEs and hospital organizational factors. Also, the SEM analysis showed a positive significant correlation between MEs and psychological and functional factors, whereby excessive workload, complexity of tasks, stress, sleep deprivation, and fatigue were found to be predictors of MEs occurrence. In comparison to the results from the university hospital, the multi-group analysis results from the governmental public hospital and the private hospital showed a significant impact of psychological and functional factors on MEs. CONCLUSION: To reduce the occurrence of MEs in hospitals, there is a need to enhance organizational safety culture. Efforts should be directed at both organizational and individual levels. Also, it is essential that health decision makers develop strategies to reduce work-related stress and improve healthcare staff well-being, as work stress may cause cognitive impairments among healthcare workers and hence threaten patients' safety.

Mechanical and hemodynamic responses of breast tissue under mammographic-like compression during functional dynamic optical imaging.

Studying tissue hemodynamics following breast compression has the potential to reveal new contrast mechanisms for evaluating breast cancer. However, how compression will be distributed and, consequently, how hemodynamics will be altered inside the compressed breast remain unclear. To explore the effect of compression, 12 healthy volunteers were studied by applying a step compression increase (4.5-53.4 N) using an optical imaging system capable of concurrently measuring pressure distribution and hemodynamic responses. Finite element analysis was used to predict the distribution of internal fluid pressure (IFP) in breast models. Comparisons between the measured pressure distribution and the reconstructed hemodynamic images for the healthy volunteers indicated significant (p < 0.05) negative correlations. The findings from a breast cancer patient showed that IFP distribution during compression strongly correlates with the observed differential hemodynamic images. We concluded that dynamic breast compression results in non-uniform internal pressure distribution throughout the breast that could potentially drive directed blood flow. The encouraging results obtained highlight the promise of developing dynamic optical imaging biomarkers for breast cancer by interpreting differential hemodynamic images of breast tissue during compression in the context of measured pressure distribution and predicted IFP.

Do modern family planning methods impact women's quality of life? Jordanian women's perspective.

BACKGROUND: Although Jordan has made progress in meeting Family Planning (FP) needs in last decades, recently the use of FP methods has declined significantly. Women's personal experiences, knowledge, and perceptions of how a FP method might impact their quality of life (QoL) can influence FP decisions. However, a lack of comprehensive understanding of the impact of modern FP methods on women's QoL continues to exist among Jordanian couples. Therefore, this study aimed to investigate the relationship between the use of common modern FP methods and QoL among Jordanian women. METHODS: Using the WHOQOL-BREF questionnaire along with other questions, non-pregnant women of reproductive age were interviewed at their homes through face-to-face structured interviews. Women who visited the obstetrics and gynecology clinic of King Abdullah University Hospital for contraceptive advice and follow-up consultations were also included. RESULTS: A total of 548 women aged between 18 and 49 participated in the study. Based on the WHOQOL-BREF scale, the overall mean (SD) scores of the four domains were found to be average. Our findings show that women who used Intra Uterine Devices (IUDs) and women whose husbands used condoms had better QoL in the four domains (physical health, psychological health, social relationships, and environment) than those who used Oral Contraceptives (OCs). Women who used implant and injectable hormonal contraceptives had better QoL in terms of the physical health and social relationships domains. In contrast, women who had undergone permanent sterilization had lower QoL scores in all of the four domains. Further analysis revealed that women who had undergone tubal sterilization were less satisfied overall and more likely to experience side effects than women who used OCs. CONCLUSION: The choice to use contraceptives and decide freely whether and when to have children is regarded as a fundamental reproductive health right and is strongly linked to women's health and QoL. Women who use OCs and women who have undergone permanent sterilization are likely to have lower QoL than women who use IUDs or implant and injectable hormones and those whose husbands use condoms.

The use of echocardiographic and clinical data recorded on admission to simplify decision making for elective percutaneous coronary intervention: a prospective cohort study.

BACKGROUND: Coronary artery disease (CAD), a leading cause of mortality, affects patient health-related quality of life (HRQoL). Elective percutaneous coronary interventions (ePCIs) are usually performed to improve HRQoL of CAD patients. The aim of this study was to design models using admission data to predict the outcomes of the ePCI treatments on the patients' HRQoL. METHODS: This prospective cohort study was conducted with CAD patients who underwent ePCIs at the King Abdullah University Hospital in Jordan from January 2014 through May 2015. Six months after their ePCI procedures, the participants completed the improved MacNew (QLMI-2) questionnaire, which was used for evaluating three domains (physical, emotional and social) of HRQoL. Multivariate linear regression was used to design models to predict the three domains of HRQoL from echocardiographic findings and clinical data that are routinely measured on admission. RESULTS: The study included 239 patients who underwent ePCIs and responded to the QLMI-2 questionnaire. The mean age (± standard deviation) of the participants was 55.74 ± 11.84 years, 54.58 ± 11.37 years for males (n = 174) and 59.11 ± 12.49 years for females (n = 65). The average scores for physical, emotional and social HRQoL were 4.38 ± 1.27, 4.4 ± 1.11, and 4.37 ± 1.32, respectively. Out of the 42 factors inputted to the models to predict HRQoL scores, 10, 9, and 9 factors were found to be significant determinants for physical, emotional and social domains, respectively, with adjusted coefficients of determination of 0.630, 0.604 and 0.534, respectively. Basophil levels on admission showed a significant positive correlation with the three domains of HRQoL, while aortic root diameter showed a negative correlation. Scores for the three domains were significantly lower in women than in men. Hypertensive and diabetic patients had significantly lower HRQoL scores than patients without hypertension and diabetes. CONCLUSION: The prediction of HRQoL scores 6 months after an ePCI is possible based on data acquired on admission. The models developed here can be used as decision-making tools to guide physicians in identifying the efficacy of ePCIs for individual patients, hence decreasing the rate of inappropriate ePCIs and reducing costs and complications.

Evaluation of infection prevention and control policies, procedures, and practices: An ethnographic study.

BACKGROUND: The intensive care unit (ICU) is considered the epicenter of infections, and patients in the ICU are at higher risk of infection because of their vulnerability, age, and lengthy hospitalization. METHODS: The ethnographic design has been used to describe, examine, and evaluate the policies and procedures that are implemented to prevent and control hospital-acquired infections (HAIs) in the medical ICU in King Abdullah University Hospital. In-depth semi-structured interviews with 23 participants supported by nonparticipant observation and document analysis were carried out to collect triangulated data. The themes and subthemes were developed through a software package and hand-coding procedure. RESULTS: Health care workers were aware but not fully engaged to prevent and control HAIs; nevertheless, they presented themselves as knowledgeable. Staff recognized the importance of involving family members and visitors. However, they had serious concern toward open visitation. The nurse to patient ratio was another challenge of infection prevention and control practices. The findings demonstrated that performing continuous prospective surveillance by highly qualified and trained staff can reduce the risk of endemic HAIs. CONCLUSIONS: The study highlighted the importance of changing behaviors and practices of health care providers and visitors to improve adherence to infection prevention and control policies and practices.

Determinants of antenatal care attendance among women residing in highly disadvantaged communities in northern Jordan: a cross-sectional study.

BACKGROUND: One of the major reproductive health challenges among disadvantaged populations is to provide pregnant women with the necessary antenatal care (ANC). In this study, we suggest applying an integrated conceptual framework aimed at ascertaining the extent to which attendance at ANC clinics may be attributed to individual determinants or to the quality of the care received. METHODS: Using a cross-sectional design, data were collected from a sample of 831 women residing in nine sub-districts in three northern governorates of Jordan and designated according to national categorization as persistent poverty pockets. All of the sampled women were recruited from public maternal and child health centers and interviewed using a structured pre-tested survey. This tool covered certain predictors, ranging from the user's attributes, including predisposing, enabling, and need factors, to the essential components of the experience of care. These components assessed the quality of ANC in terms of five elements: woman-provider relations, technical management, information exchange, continuity of care, and appropriate constellation of services. Adequate ANC content was assessed in relation to the frequency of antenatal visits and the time of each visit. RESULTS: The results of multivariate logistic regression analyses show that the use of ANC facilities is affected by various factors related to the quality of service delivery. These include receiving information and education on ANC during clinic visits (OR = 9.1; 95% CI = 4.9-16.9), providing pregnant women with opportunities for dialogue and health talks (OR = 7.2; 95% CI = 4.1-12.8), having scheduled follow-up appointments (OR = 6.5; 95% CI = 3.5-12.0), and offering dignified and respectful care (OR = 5.7; 95% CI = 2.5-13.1). At the individual level, our findings have identified a woman's education level (OR = 1.2; 95% CI = 1.1-1.3), desire for the pregnancy (OR = 1.7; 95% CI = 1.1-2.7), and living in a district served by an ANC clinic (OR = 4.3; 95% CI = 2.3-8.1) as determinants affecting ANC utilization. CONCLUSION: Taking women's experiences of ANC as a key metric for reporting the quality of the care is more likely to lead to increased utilization of ANC services by women in highly disadvantaged communities. Our findings suggest that the degree to which women feel that they are respected, informed, and engaged in their care has potential favorable implications for ANC.

The Impact of Applying Quality Management Practices on Patient Centeredness in Jordanian Public Hospitals: Results of Predictive Modeling.

Targeting the patient's needs and preferences has become an important contributor for improving care delivery, enhancing patient satisfaction, and achieving better clinical outcomes. This study aimed to examine the impact of applying quality management practices on patient centeredness within the context of health care accreditation and to explore the differences in the views of various health care workers regarding the attributes affecting patient-centered care. Our study followed a cross-sectional survey design wherein 4 Jordanian public hospitals were investigated several months after accreditation was obtained. Total 829 clinical/nonclinical hospital staff members consented for study participation. This sample was divided into 3 main occupational categories to represent the administrators, nurses, as well as doctors and other health professionals. Using a structural equation modeling, our results indicated that the predictors of patient-centered care for both administrators and those providing clinical care were participation in the accreditation process, leadership commitment to quality improvement, and measurement of quality improvement outcomes. In particular, perceiving the importance of the hospital's engagement in the accreditation process was shown to be relevant to the administrators (gamma = 0.96), nurses (gamma = 0.80), as well as to doctors and other health professionals (gamma = 0.71). However, the administrator staff (gamma = 0.31) was less likely to perceive the influence of measuring the quality improvement outcomes on the delivery of patient-centered care than nurses (gamma = 0.59) as well as doctors and other health care providers (gamma = 0.55). From the nurses' perspectives only, patient centeredness was found to be driven by building an institutional framework that supports quality assurance in hospital settings (gamma = 0.36). In conclusion, accreditation is a leading factor for delivering patient-centered care and should be on a hospital's agenda as a strategy for continuous quality improvement.

Using decision trees to explore the association between the length of stay and potentially avoidable readmissions: A retrospective cohort study.

BACKGROUND: There is a growing concern that reduction in hospital length of stay (LOS) may raise the rate of hospital readmission. This study aims to identify the rate of avoidable 30-day readmission and find out the association between LOS and readmission. METHODS: All consecutive patient admissions to the internal medicine services (n = 5,273) at King Abdullah University Hospital in Jordan between 1 December 2012 and 31 December 2013 were analyzed. To identify avoidable readmissions, a validated computerized algorithm called SQLape was used. The multinomial logistic regression was firstly employed. Then, detailed analysis was performed using the Decision Trees (DTs) model, one of the most widely used data mining algorithms in Clinical Decision Support Systems (CDSS). RESULTS: The potentially avoidable 30-day readmission rate was 44%, and patients with longer LOS were more likely to be readmitted avoidably. However, LOS had a significant negative effect on unavoidable readmissions. CONCLUSIONS: The avoidable readmission rate is still highly unacceptable. Because LOS potentially increases the likelihood of avoidable readmission, it is still possible to achieve a shorter LOS without increasing the readmission rate. Moreover, the way the DT model classified patient subgroups of readmissions based on patient characteristics and LOS is applicable in real clinical decisions.

Risk assessment of comorbidities on 30-day avoidable hospital readmissions among internal medicine patients.

RATIONALE, AIMS AND OBJECTIVES: Reducing the rate of hospital readmissions, particularly avoidable ones, has significant implications on patient outcomes, cost containment, and quality of care. Given that the reason of readmission may differ from the patient's main diagnosis in the index admission, this study aims to assess the influence of index comorbidities on the primary readmission diagnoses and explore the risk of deemed avoidable readmission because of prior comorbidities. METHODS: A retrospective review of 3962 discharges was conducted at a 527-bed teaching hospital in Jordan, utilizing data related to 2025 internal medicine patients. RESULTS: Among all discharges, 29% were followed by a 30-day readmission, of which 13% were identified as potentially avoidable. Of all readmissions, 36% of patients were readmitted because of one of the comorbidities that had been identified at index admission. In addition, 47% of the potentially avoidable readmissions had a main diagnosis that was one of the index comorbidities. The results also showed an association between readmission for one of the index stay's comorbidities and being avoidable, with an adjusted odds ratio of 2.12 (95% confidence interval, 1.65-2.72). Overall, the presence of certain diseases, being identified as one of the preceding comorbidities, was found to have a substantial influence on the risk of potentially avoidable readmission. These diseases included digestive, circulatory, respiratory, genitourinary systems, and infectious and parasitic diseases (adjusted relative risks = 1.57, 1.49, 1.36, 1.30, and 2.30, respectively). CONCLUSION: To help reduce the rates of readmission, potential gains seem available if hospitals adopt clinical practices that support the patient's care during the post-discharge transition. This implies that health care providers need to pay more attention to the comorbidities of high-risk patients to be closely monitored after discharge.

The Effects of Negative Reinforcement on Increasing Patient Adherence to Appointments at King Abdullah University Hospital in Jordan.

Appointment nonadherence is a health behavior that represents a burden to health care systems. On March 1, 2015, a new negative reinforcement intervention involving "service fees" for a visit without appointment was implemented at King Abdullah University Hospital in Jordan. To evaluate the effect of this intervention in improving patient adherence to medical appointment, a retrospective preintervention and postintervention analysis was used, including all patients (n = 65 535) who had scheduled appointments at 39 outpatient clinics. A repeated-measures analysis of variance was first performed. Then, a multivariate linear regression model was used to identify factors that might predict individuals who are likely to attend or miss their appointments and those who have a greater tendency to visit the hospital with or without appointments. Although the average percentage of appointments attended was more than missed preintervention and postintervention, the decrease in percentage of missed appointments was more pronounced postintervention. Also, the average percentage of visits without appointments was less than visits with appointments in both times, but the decrease in the percentage of visits without appointments was more prominent after. The regression analysis revealed that younger, married and male patients were more likely to miss their appointment before and after the intervention. Also, younger patients had a tendency to attend without appointments. Conversely, patients with the lower copayment rate had a tendency to adhere to appointment times. In conclusion, negative reinforcement interventions could improve patient appointment adherence rates. Accordingly, interventions designed that consider evidence and are theory-based are needed to change patient behavior.

Integrating the Principles of Evidence Based Medicine and Evidence Based Public Health: Impact on the Quality of Patient Care and Hospital Readmission Rates in Jordan.

INTRODUCTION: Hospital readmissions impose not only an extra burden on health care systems but impact patient health outcomes. Identifying modifiable behavioural risk factors that are possible causes of potentially avoidable readmissions can lower readmission rates and healthcare costs. METHODS: Using the core principles of evidence based medicine and public health, the purpose of this study was to develop a heuristic guide that could identify what behavioural risk factors influence hospital readmissions through adopting various methods of analysis including regression models, t-tests, data mining, and logistic regression. This study was a retrospective cohort review of internal medicine patients admitted between December 1, 2012 and December 31, 2013 at King Abdullah University Hospital, in Jordan. RESULTS: 29% of all hospitalized patients were readmitted during the study period. Among all readmissions, 44% were identified as potentially avoidable. Behavioural factors including smoking, unclear follow-up and discharge planning, and being non-compliant with treatment regimen as well as discharge against medical advice were all associated with increased risk of avoidable readmissions. CONCLUSION: Implementing evidence based health programs that focus on modifiable behavioural risk factors for both patients and clinicians would yield a higher response in terms of reducing potentially avoidable readmissions, and could reduce direct medical costs.
