How soon should serum potassium levels be monitored for patients started on diuretics?

Case series show that hypokalemia following initiation of diuretic therapy occurs in most patients within 2 to 8 weeks. However, no studies are available that adequately predict the risk of this complex and multifactorial condition. Patients taking diuretics should have a potassium level checked in the first 2 to 8 weeks after initiating therapy. Mild hypokalemia (3.1 to 3.4 mmol/L) may be transient, so a repeat measurement may be considered before initiating potassium replacement. Dietary sodium restriction may also help to conserve potassium, because this will decrease urinary flow rate and potassium loss. The frequency with which to check potassium levels should be guided by the patients' underlying clinical conditions and dietary potassium and sodium intake.

Projected Deaths of Despair from COVID-19

More Americans could lose their lives to deaths of despair, deaths due to drug, alcohol, and suicide, if we do not do something immediately. Deaths of despair have been on the rise for the last decade, and in the context of COVID-19, deaths of despair should be seen as the epidemic within the pandemic. The goal of this report is to predict what deaths of despair we might see based on three assumptions during COVID-19: economic recovery, relationship between deaths of despair and unemployment, and geography. Across nine different scenarios, additional deaths of despair range from 27,644 (quick recovery, smallest impact of unemployment on deaths of despair) to 154,037 (slow recovery, greatest impact of unemployment on deaths of despair), with somewhere in the middle being around 68,000. However, these data are predictions. We can prevent these deaths by taking meaningful and comprehensive action as a nation

How can I improve patient adherence to prescribed medication?

Two randomized clinical trials have shown that simplified dosing schedules have improved patient adherence to medication as prescribed. Some, but not all, randomized controlled trials show multidimensional interventions can also improve adherence. These interventions include combinations of patient and family education, home monitoring of disease status, and increased convenience of care, such as workplace access.

Birth outcomes in Colorado's undocumented immigrant population

BACKGROUND: The birth outcomes of undocumented women have not been systematically studied on a large scale. The growing number of undocumented women giving birth in the United States has important implications for clinical care and public health policy. The objective of this study was to describe birth outcomes of undocumented immigrants in Colorado. METHODS: Retrospective descriptive study of singleton births to 5961 undocumented women using birth certificate data for 1998–1999. RESULTS: Undocumented mothers were younger, less educated, and more likely to be single. They had higher rates of anemia, were less likely to gain enough weight, and less likely to receive early prenatal care. They were much less likely to use alcohol or tobacco. Undocumented women had a lower rate of low birth weight (5.3% v 6.5%, P < .001) or preterm infants (12.9% v 14.5%; p = .001). Undocumented women experienced higher rates of labor complications including excessive bleeding (2.3% v 0.8%, p < .001) and fetal distress (8.7% v 3.6%, p < .001). CONCLUSION: Undocumented women have lower rates of preterm delivery and low birth weight infants, but higher rates of pregnancy related risk factors. Higher prevalence of some risk factors which are amenable to medical intervention reveals the need for improved prenatal care in this group

Assessing Adverse Events in Madeira Primary

In last three decades, several epidemiological studies have been developed in order to assess the magnitude, nature and type of adverse events (AEs). Most of these studies focus on hospital settings, where the activities are more standardised, but imultaneously more complex and involving higher risks. However, in the last years, there is a growing movement and strong evidence that point out the importance of studying other healthcare contexts, such as primary care and long-term care. In Portugal, studies on primary care setting are scarce and still in the early stages. In this article, the authors describe the AEs assessment in Portuguese Primary Health Care (PHC) units in Madeira Island/Portugal. This study was quantitative, cross-sectional, observational and analytical, with probability sampling. We quantify and analyse the AEs registered by healthcare providers using the APEAS-PT formulary. A link to the APEAS–PT form was sent to 520 healthcare professionals (111 specialist in Family Medicine, 27 medical students, 382 nurses) who worked in 32 PHC centres. These professionals identified and analysed 85 AEs and 42 incidents, which corresponds to a prevalence of 3.9 AEs per 10,000 visits,with a 95% confidence interval (CI) between 3.7 and 4 AE. Most of the AEs were preventable (96%). The most frequent causal factors of AEs were associated with medication (69%), health care provided to users (54%), communication (41%) and diagnosis (22%). This analysis of AEs in Madeira island PHC contributed to reinforce patient safety culture and to better understand quaternary prevention.info:eu-repo/semantics/publishedVersio

A Cluster Randomized Trial of Routine HIV-1 Viral Load Monitoring in Zambia: Study Design, Implementation, and Baseline Cohort Characteristics

The benefit of routine HIV-1 viral load (VL) monitoring of patients on antiretroviral therapy (ART) in resource-constrained settings is uncertain because of the high costs associated with the test and the limited treatment options. We designed a cluster randomized controlled trial to compare the use of routine VL testing at ART-initiation and at 3, 6, 12, and 18 months, versus our local standard of care (which uses immunological and clinical criteria to diagnose treatment failure, with discretionary VL testing when the two do not agree).Dedicated study personnel were integrated into public-sector ART clinics. We collected participant information in a dedicated research database. Twelve ART clinics in Lusaka, Zambia constituted the units of randomization. Study clinics were stratified into pairs according to matching criteria (historical mortality rate, size, and duration of operation) to limit the effect of clustering, and independently randomized to the intervention and control arms. The study was powered to detect a 36% reduction in mortality at 18 months.From December 2006 to May 2008, we completed enrollment of 1973 participants. Measured baseline characteristics did not differ significantly between the study arms. Enrollment was staggered by clinic pair and truncated at two matched sites.A large clinical trial of routing VL monitoring was successfully implemented in a dynamic and rapidly growing national ART program. Close collaboration with local health authorities and adequate reserve staff were critical to success. Randomized controlled trials such as this will likely prove valuable in determining long-term outcomes in resource-constrained settings.Clinicaltrials.gov NCT00929604

Adapting Boot Camp Translation Methods to Engage Clinician/Patient Research Teams Within Practice-Based Research Networks

Purpose: Boot camp translation is a proven process to engage community members and health professionals in translating and disseminating evidence-based “best practices” models for health prevention and chronic illness care. Primary care practice improvement studies, particularly involving patient-driven change, as seen with self-management support (SMS), require engaged practice teams that include patients. Models of engagement such as boot camp translation may be effective. Methods: Four geographically dispersed practice-based research networks (PBRNs) from the Meta-LARC consortium engaged 16 practices to form SMS implementation teams involving a clinician, care manager, and 2 patients in each team. Our study adapted the boot camp translation model to engage the implementation teams in describing patient SMS, studying the Agency for Healthcare Research and Quality’s SMS Resource Library, and adapting and implementing self-management tools at each practice site. Testimonials and quotes were collected across the 4 PBRNs through a facilitated brainstorming discussion and consensus model at each PBRN kickoff meeting to address the focused question, “What do patients want and need in order to self-manage their chronic illnesses?” Results: Testimonials collected across the 4 PBRNs and participation levels indicated there was a high degree of engagement in the boot camp translation process across the PBRNs and the practices. Each PBRN developed themes expressed by patients and the practices regarding what patients want and need to self-manage their illnesses. Each practice selected, adapted, and implemented an SMS tool. Conclusions: Results suggest that adapted boot camp translation was effective in guiding multiple practices to implement self-management support tools for the INSTTEPP trial. Additional study of the adapted boot camp translation process in practice quality improvement and practice redesign studies is needed

How to Translate Self-Management Support Tools Into Clinical Practice

Purpose: Patient self-management is an inevitable part of the work of being a patient, and self-management support (SMS) has become increasingly important in chronic disease management. However, the majority of SMS resources available in the Agency for Healthcare Research and Quality SMS Resource Library were developed without explicit collaboration between clinicians and patients. Methods: Translation of SMS tools derived from the library into primary care practices occurred utilizing boot camp translation in four different practice-based research networks (PBRNs). The typical model of boot camp translation was adapted for the purpose of the Implementing Networks’ Self-management Tools Through Engaging Patients and Practices (INSTTEPP) study to develop SMS tools for implementation in the participating practices. Clinicians, clinic staff members, and patients were involved throughout the translation process. Existing resources from the SMS library were reviewed and adapted by each boot camp translation group to create tools unique to the patients in each network. Results: There was no preexisting resource within the library that was deemed suitable for implementation without modification. Each network adapted tools from the SMS library to create different products. Common themes emerged from each network’s translation process that highlighted the importance of patient engagement in the translation process. Boot camp translation, in conjunction with PBRNs, can be implemented to adapt SMS tools for implementation in member practices. Conclusions: Boot camp translation with a combination of practices and patients can be implemented to facilitate a process of local adaptation that improves the local applicability of SMS tools in primary care clinics

Demonstration of the temporal matter-wave Talbot effect for trapped matter waves

We demonstrate the temporal Talbot effect for trapped matter waves using ultracold atoms in an optical lattice. We investigate the phase evolution of an array of essentially non-interacting matter waves and observe matter-wave collapse and revival in the form of a Talbot interference pattern. By using long expansion times, we image momentum space with sub-recoil resolution, allowing us to observe fractional Talbot fringes up to 10th order.Comment: 17 pages, 7 figure
