What makes a “successful” or “unsuccessful” discharge letter? Hospital clinician and General Practitioner assessments of the quality of discharge letters
Background
Sharing information about hospital care with primary care in the form of a discharge summary is essential to patient safety. In the United Kingdom, although discharge summary targets on timeliness have been achieved, the quality of discharge summaries’ content remains variable.
Methods
Mixed methods study in West Midlands, England with three parts: 1. General Practitioners (GPs) sampling discharge summaries they assessed to be “successful” or “unsuccessful” exemplars, 2. GPs commenting on the reasons for their letter assessment, and 3. surveying the hospital clinicians who wrote the sampled letters for their views. Letters were examined using content analysis; we coded 15 features (e.g. “diagnosis”, “GP plan”) based on relevant guidelines and standards. Free text comments were analysed using corpus linguistics, and survey data were analysed using descriptive statistics.
Results
Fifty-three GPs participated in selecting discharge letters; 46 clinicians responded to the hospital survey. There were statistically significant differences between “successful” and “unsuccessful” inpatient letters (
n
= 375) in relation to inclusion of the following elements: reason for admission (99.1% vs 86.5%); diagnosis (97.4% vs 74.5%), medication changes (61.5% vs 48.9%); reasons for medication changes (32.1% vs 18.4%); hospital plan/actions (70.5% vs 50.4%); GP plan (69.7% vs 53.2%); information to patient (38.5% vs 24.8%); tests/procedures performed (97.0% vs 74.5%), and test/examination results (96.2% vs 77.3%). Unexplained acronyms and jargon were identified in the majority of the sample (≥70% of letters). Analysis of GP comments highlighted that the overall clarity of discharge letters is important for effective and safe care transitions and that they should be relevant, concise, and comprehensible. Hospital clinicians identified several barriers to producing “successful” letters, including: juniors writing letters, time limitations, writing letters retrospectively from patient notes, and template restrictions.
Conclusions
The failure to uniformly implement national discharge letter guidance into practice is continuing to contribute to unsuccessful communication between hospital and general practice. While the study highlighted barriers to producing high quality discharge summaries which may be addressed through training and organisational initiatives, it also indicates a need for ongoing audit to ensure the quality of letters and so reduce patient risk at the point of hospital discharge.

Researching quality in care transitions : international perspectives
\"This book is concerned with the complexities of achieving quality in care transitions. The organization and accomplishment of high quality care transitions relies upon the coordination of multiple professionals, working within and across multiple care processes, settings and organizations, each with their own distinct ways of working, profile of resources, and modes of organizing. In short, care transitions might easily be regarded as complex activities that take place within complex systems, which can make accomplishing high quality care challenging. As a subject of enquiry, care transitions are approached from many research, improvement and policy perspectives: from group psychology and human factors to social and political theory; from applied process re-engineering projects to exploratory ethnographic studies; from large-scale policy innovations to local improvements initiatives. This collection will provide a unique cross-disciplinary and multi-level analysis, where each chapter presents a particular depth of insight and analysis, and together offer a holistic and detail understand of care transitions.\"-- Provided by publisher.

Linking Dynamic Water Storage and Subsurface Geochemical Structure Using High‐Frequency Concentration‐Discharge Records
Shifts in water fluxes and chemical heterogeneity through catchments combine to dictate stream solute export from the Critical Zone. The ways in which these factors emerge in resultant concentration‐discharge (C‐Q) relationships remain obscure, particularly at the timescale of individual precipitation and discharge events. Here we take advantage of a new high‐frequency, multi‐element and multi‐event stream C‐Q data set. The stream solute concentrations of seven major ions were recorded every 40 min over five flood events spanning one hydrologic year in a French agricultural watershed (Orgeval) using a lab‐in‐the‐field deployment we refer to as a “River Lab.” We focus attention on the recession periods of these events to consider how geochemical heterogeneity within the catchment translates into dynamic stream solute concentrations during shifts in water storage. We first show that for C‐Q relationships resulting from data acquisition over multiple flood events, lumping all trends together can lead to biases in characteristic C‐Q parameters. We then reframe C‐Q relationships using a simple recession curve analysis to consider how hydrological processes produce chemical mixing of distinct solute pools immediately following discharge events. We find three distinct classes of behavior among the major solutes, none of which can be interpreted based on water storage changes alone. The shape of C‐Q relationships for each solute can then be related to their vertical zonation in the subsurface of Orgeval, and to the capacity for subcomponents of these distributions to be readily mobilized during a discharge event. Key Points We combine high‐frequency (every 40 min) stream chemistry data and stream discharge recession analysis We propose a conceptual model for the relationship between water storage and solute export at the Orgeval Critical Zone Observatory (CZO), France Three classes of solute behavior are identified at the Orgeval CZO, related to the role of rock dissolution and amendments in their budget

Study on the Characteristics of O3 Concentration in Air Discharges Based on Differential Detection Methods
Addressing the challenges of achieving highly reliable online monitoring for switchgear discharge phenomena and the unclear patterns of O3 concentration generation, this paper investigates the characteristics of O3 concentration in air discharges using a differential detection method. The research focuses on two aspects: equipment enhancement and pattern validation. A novel O3 concentration detection method based on differential signal acquisition is proposed, and corresponding apparatus is developed. By establishing a corona discharge experimental platform, the study systematically investigates the influence patterns of temperature, discharge duration, and duct length on O3 generation concentration. The findings provide a robust, interference-resistant approach for online monitoring of switchgear insulation status while elucidating the generation mechanisms of O3 concentration.

Submarine groundwater discharge as a major source of nutrients to the Mediterranean Sea
The Mediterranean Sea (MS) is a semienclosed basin that is considered one of the most oligotrophic seas in the world. In such an environment, inputs of allochthonous nutrients and micronutrients play an important role in sustaining primary productivity. Atmospheric deposition and riverine runoff have been traditionally considered the main external sources of nutrients to the MS, whereas the role of submarine groundwater discharge (SGD) has been largely ignored. However, given the large Mediterranean shore length relative to its surface area, SGD may be a major conveyor of dissolved compounds to the MS. Here, we used a ²²⁸Ra mass balance to demonstrate that the total SGD contributes up to (0.3–4.8)⋅10 ¹² m ³⋅y ⁻¹ to the MS, which appears to be equal or larger by a factor of 16 to the riverine discharge. SGD is also a major source of dissolved inorganic nutrients to the MS, with median annual fluxes of 190⋅10 ⁹, 0.7⋅10 ⁹, and 110⋅10 ⁹ mol for nitrogen, phosphorous, and silica, respectively, which are comparable to riverine and atmospheric inputs. This corroborates the profound implications that SGD may have for the biogeochemical cycles of the MS. Inputs of other dissolved compounds (e.g., iron, carbon) via SGD could also be significant and should be investigated.
Significance The Mediterranean Sea (MS) is one of the most oligotrophic seas in the world, and external inputs of nutrients are especially relevant to sustaining primary productivity in this basin. Here we evaluate the role of submarine groundwater discharge (SGD) as a source of nutrients to the entire MS, a pathway that has been largely overlooked. This study demonstrates that SGD is a volumetrically important process in the MS, is of a larger magnitude than riverine discharge, and also represents a major source of dissolved inorganic nitrogen, phosphorous, and silica to the MS.

Comparing Assimilation of Remotely Sensed Discharge Derived From SWOT and Landsat Into a Global Hydrological Model
The Surface Water and Ocean Topography (SWOT) satellite has enabled river discharge estimation for global rivers including ungauged regions. This remotely sensed discharge (SwRSQ) generated from SWOT's cloud‐penetrating measurements of river widths, water surface elevation, and slope is expected to have improved accuracy and spatiotemporal coverage over existing methods using Landsat‐derived river widths (LsRSQ). Previous studies demonstrated that the assimilation of LsRSQ into a global hydrological model resulted in improved estimation of river discharge, yet to date SwRSQ assimilation has not been explored. Therefore, this study assimilated SwRSQ into a global hydrological model and evaluated the assimilation performance compared to LsRSQ over the Missouri River basin as a hydrologically complex test case. Results show that the RSQ assimilation reduced skill metrics relative to model‐only and RSQ‐only estimates. The assimilation of SwRSQ showed a significant improvement over the baseline simulation, reducing PBIAS by 34.1% and NRMSE by 0.435. Moreover, assimilating SwRSQ outperformed assimilating LsRSQ at 74% and 76% of gauging stations in terms of NSE and KGE, respectively, based on comparisons between the two data assimilation experiments. Improvements were most pronounced in regions with poor baseline performance, where SWOT's higher observation frequency contributed to such improvements over Landsat. In contrast, in areas well represented by the baseline model, LsRSQ occasionally performed better. Simultaneous assimilation of SwRSQ and LsRSQ showed further improvements at rivers with low‐skill baseline result. These findings highlight the value of SWOT‐derived RSQ and its synergistic potential with other satellite products in advancing global‐scale hydrological modeling and monitoring.

Remote Sensing of Discharge Ratios at River Channel Bifurcations
River channel bifurcations are crucial for distributing water and sediment on floodplains and deltas, but estimating discharge ratios between branches remains challenging. Using satellite imagery and in‐situ discharge data, we demonstrate that bifurcate channel widths can estimate discharge ratios at 23 of 27 bifurcations in 11 rivers worldwide, with good accuracy (R2 = 0.80) in 26 of 33 measurements. An empirical width‐discharge equation derived from 5,740 United States Geological Survey gauging stations further improves accuracy (R2 = 0.82). For best results, branch widths should be measured within one channel width of the bifurcation. The method is ineffective in cases influenced by tributaries, avulsion, or multiple branches. We conclude that channel width is effective for estimating discharge ratios, especially when paired with an empirical width‐discharge equation, potentially enhancing river discharge estimates from the Surface Water and Ocean Topography satellite mission, which currently lacks flow partitioning capabilities for bifurcations. Plain Language Summary River bifurcations, where a river splits into two or more branches, play an important role in spreading water and sediment across floodplains and deltas. However, estimating how much water flows through each branch is often difficult. In our study, we used satellite images and on‐the‐ground measurements to show that channel width can be used to estimate how much water flows through different branches. This method worked well for most of the bifurcations we studied across 11 rivers globally. We also found that using an equation based on U.S. river data improved the accuracy of our estimates. The best results were obtained when the channel width was measured close to the point where the river splits. The method did not work well when tributaries or other factors affected the flow. Overall, our approach could help improve river flow estimates from satellite missions like Surface Water and Ocean Topography, which currently do not handle bifurcations well. Key Points Remotely sensed channel widths accurately estimate discharge ratios at river bifurcations, succeeding for 23 of 27 sites worldwide Width‐discharge equation from United States Geological Survey data improves discharge ratio estimates, achieving higher accuracy for global rivers Width method, optimal within one channel width downstream, could enhance Surface Water and Ocean Topography satellite discharge estimates for anabranching rivers

Potential role of permafrost thaw on increasing Siberian river discharge
Despite the increasing Siberian river discharge, the sensitivity of streamflow to climate forcing/permafrost thawing is poorly quantified. Based on the Budyko framework and superposition principles, we detected and attributed the changes in streamflow regimes for the three great Siberian rivers (Ob, Yenisei, and Lena) during 1936–2019. Over the past 84 years, streamflow of Ob, Yenisei and Lena has increased by ∼7.7%, 7.4% and 22.0%, respectively. Intensified precipitation induced by a warming climate is a major contributor to increased annual streamflow. However, winter streamflow appears to be particularly sensitive to temperature. Whilst rising temperature can reduce streamflow via evapotranspiration, it can enhance groundwater discharge to rivers due to permafrost thawing. Currently, every 1 °C rise in temperature likely leads to 6.1%–10.5% increase in groundwater discharge, depending on the permafrost condition. For permafrost-developed basins, the contribution to increased streamflow from thawing permafrost will continue to increase in the context of global warming.

Patient Activation and 30-Day Post-Discharge Hospital Utilization
ABSTRACT
BACKGROUND
Patient activation is linked to better health outcomes and lower rates of health service utilization. The role of patient activation in the rate of hospital readmission within 30 days of hospital discharge has not been examined.
METHODS
A secondary analysis using data from the Project RED-LIT randomized controlled trial conducted at an urban safety net hospital. Data from 695 English-speaking general medical inpatient subjects were analyzed. We used an adapted, eight-item version of the validated Patient Activation Measure (PAM). Total scores were categorized, according to standardized methods, as one of four PAM levels of activation: Level 1 (lowest activation) through Level 4 (highest activation). The primary outcome measure was total 30-day post-discharge hospital utilization, defined as total emergency department (ED) visits plus hospital readmissions including observation stays. Poisson regression was used to control for confounding.
RESULTS
Of the 695 subjects, 67 (9.6 %) were PAM Level 1, 123 (17.7 %) were Level 2, 193 (27.8 %) were Level 3, and 312 (44.9 %) were Level 4. Compared with highly activated patients (PAM Level 4), a higher rate of 30-day post-discharge hospital utilization was observed for patients at lower levels of activation (PAM Level 1, incident rate ratio [IRR] 1.75, 95 % CI,1.18 to 2.60) and (PAM Level 2, IRR 1.50, 95 % CI 1.06 to 2.13). The rate of returning to the hospital among patients at PAM Level 3 was not statistically different than patients with PAM Level 4 (IRR 1.30, 95 % CI, 0.94 to 1.80). The rate ratio for PAM Level 1 was also higher compared with Level 4 for ED use alone (1.68(1.07 to 2.63)) and for hospital readmissions alone (1.93 [1.22 to 3.06]).
CONCLUSION
Hospitalized adult medical patients in an urban academic safety net hospital with lower levels of Patient Activation had a higher rate of post-discharge 30-day hospital utilization.
