Re-evaluation of re-hospitalization and rehabilitation in renal research.

ABSTRACT: The use of administrative data to capture 30-day readmission rates in end-stage renal disease is challenging since Medicare combines claims from acute care, inpatient rehabilitation (IRF), and long-term care hospital stays into a single "Inpatient" file. For data prior to 2012, the United States Renal Data System does not contain the variables necessary to easily identify different facility types, making it likely that prior studies have inaccurately estimated 30-day readmission rates.For this report, we developed two methods (a "simple method" and a "rehabilitation-adjusted method") to identify acute care, IRF, and long-term care hospital stays from United States Renal Data System claims data, and compared them to methods used in previously published reports.We found that prior methods overestimated 30-day readmission rates by up to 12.3% and overestimated average 30-day readmission costs by up to 11%. In contrast, the simple and rehabilitation-adjusted methods overestimated 30-day readmission rates by 0.1% and average 30-day readmission costs by 1.8%. The rehabilitation-adjusted method also accurately identified 96.8% of IRF stays.Prior research has likely provided inaccurate estimates of 30-day readmissions in patients undergoing dialysis. In the absence of data on specific facility types particularly when using data prior to 2012, future researchers could employ our method to more accurately characterize 30-day readmission rates and associated outcomes in patients with end-stage renal disease.

Project description:INTRODUCTION:Our previous work demonstrated that the 99mTc renal tracer, 99mTc(CO)3(FEDA) (99mTc-1), has a rapid clearance comparable in rats to that of 131I-OIH, the radioactive gold standard for the measurement of effective renal plasma flow. The uncharged fluoroethyl pendant group of 99mTc-1 provides a route to the synthesis of a structurally analogous rhenium-tricarbonyl 18F renal imaging agent, Re(CO)3([18F]FEDA) (18F-1). Our goal was to develop an efficient one-step method for the preparation of 18F-1 and to compare its pharmacokinetic properties with those of 131I-OIH in rats. METHODS:18F-1 was prepared by the nucleophilic 18F-fluorination of its tosyl precursor. The labeled compound was isolated by HPLC and subsequently evaluated in Sprague-Dawley rats using 131I-OIH as an internal control and by dynamic PET/CT imaging. Plasma protein binding (PPB) and erythrocyte uptake (RCB) were determined and the urine was analyzed for metabolites. RESULTS:18F-1 was efficiently prepared as a single species with high radiochemical purity (>99%) and it displayed high radiochemical stability in vitro and in vivo. PPB was 87% and RCB was 21%. Biodistribution studies confirmed rapid renal extraction and high specificity for renal excretion, comparable to that of 131I-OIH, with minimal hepatic/gastrointestinal elimination. The activity in the urine, as a percentage of 131I-OIH, was 92% and 95% at 10 and 60?min, respectively. All other organs (heart, spleen, lungs) showed a negligible tracer uptake (<0.4% ID). Dynamic microPET/CT imaging demonstrated rapid transit of 18F-1 through the kidneys and into the bladder; there was no demonstrable activity in bone verifying the absence of free [18F]fluoride. CONCLUSIONS:18F-1 exhibited a high specificity for the kidney, rapid renal excretion comparable to that of 131I-OIH and high in vivo radiochemical stability. Not only is 18F-1 a promising PET renal tracer, but it provides a route to the development of a pair of analogous 18F/99mTc renal imaging agents with almost identical structures and comparable pharmacokinetic properties. These promising in vivo results warrant subsequent evaluation in humans.

Project description:ObjectiveEffective stroke care does not end with acute treatment during hospitalization, but extends through rehabilitation and secondary stroke prevention. In transitions across care environments, stroke patients are vulnerable to errors in communication of diagnosis and treatment. This study aimed to demonstrate that formalized communication between the neurology team and the rehabilitation medicine team would promote secondary stroke prevention and minimize interruptions during rehabilitation.MethodsThe intervention was a standardized verbal handoff by phone between the discharging neurology resident and the admitting rehabilitation resident regarding each patient at transfer. This retrospective cohort study compared a pre-intervention control group (September 2012 to February 2013) and a post-intervention group transferred with the handoff (September 2013 to January 2014). The outcomes measured included errors in communication of stroke severity, stroke mechanism, medications, and recommended follow-up (appointments and tests) as well as emergent brain imaging, return to the acute care facility, and readmission.ResultsThe pre- and post-intervention groups were similar with respect to number of patients (50 vs. 52) and demographics including gender (52 vs. 54% female), age (65.8 vs. 64.0?years), severity of illness as measured by the National Institutes of Health Stroke Scale (NIHSS) (10 vs. 6.5), and stroke type (84 vs. 77% ischemic). Implementation of the handoff decreased errors in communication of diagnosis (NIHSS 92 vs. 74%, p?=?0.02; stroke mechanism 54 vs. 30%, p?=?0.02). Furthermore, the handoff decreased the proportion with errors in reconciliation of critical medications (42 vs. 23%, p?=?0.04). However, the intervention did not significantly reduce interruptions of the rehabilitation program, such as emergent brain imaging (8 vs. 12%, p?=?0.55), or transfers back to the acute care hospital (26 vs. 21%, p?=?0.56).ConclusionStandardized handoffs decreased errors in communication of diagnosis and critical medications for secondary stroke prevention.

Project description:Plain English summary:Patient and public involvement (PPI) is increasingly recognised as important in research. Most PPI takes place face-to-face, but this can be difficult for people who are unwell or have caring responsibilities. As these challenges are particularly common in palliative care and rehabilitation research, we developed an online forum for PPI: www.csipublicinvolvement.co.uk. In this study, we explored how well the online forum worked, if it is a suitable method for PPI, and how PPI members and researchers reacted to using it. We used an existing theory about online interventions to help choose the 'right' questions to ask participants. We invited PPI members and researchers who had used the online forum to participate in focus groups, and identified the most important themes discussed. Within this study, PPI members have helped with the interview questions, analysis, and write up. Overall, four PPI members and five researchers participated in the focus groups. Participants felt the online forum worked well and had multiple benefits. From the discussions, we identified four key questions to consider when developing online methods for PPI: how does the forum work, how does it engage people, how does it empower people, and what is the impact? Participants suggested the forum could be improved by being more PPI and less researcher focused. We conclude that when developing online methods of PPI, a functioning forum is not enough: it also needs to be engaging and empowering to have an impact. Future work can use these four domains when developing their own online PPI methods. Abstract: Background:Patient and public involvement (PPI) in research is increasingly recognised as important. Most PPI activities take place face-to-face, yet this can be difficult for people with ill health or caring responsibilities, and may exclude people from hard-to-reach populations (e.g. living in vulnerable social circumstances and/or remote geographical locations). These challenges are particularly pertinent in palliative care and rehabilitation research where people often live with, or care for someone with, advanced illness. In response to this, we aimed to test the functionality, feasibility, and acceptability of an online forum for PPI for palliative care and rehabilitation research (www.csipublicinvolvement.co.uk). Methods:We conducted separate focus groups with PPI members and researchers who had used the online forum. Data collection was underpinned by DeLone and Mclean's model of information systems success. Focus groups were recorded, transcribed, and analysed using inductive thematic analysis. Dual coding by two authors ensured rigour, and attention was paid to divergent cases. Results:Four PPI members and five researchers participated in the focus groups (two PPI focus groups, one researcher focus group). The online forum was perceived as functional, feasible, and acceptable. Our analysis identified four key questions to consider when developing online methods for PPI: (1) how does the forum work, (2) how does it engage people, (3) how does it empower people, and (4) what is the impact? PPI members felt that the online forum was too researcher led, and needed to be more PPI focussed. Conclusions:When developing online methods of PPI, a functioning forum is not enough: it also needs to be engaging and empowering to have an impact. To optimise online involvement, future work should refer to these four domains and balance the needs of researchers and PPI members.

Project description:OBJECTIVES:Chronic respiratory diseases exert a global health burden with high health care costs, morbidity, and mortality. The aim of the present study was to investigate the effect of pulmonary rehabilitation (PR) on emergency admission and hospitalization rates of patients with chronic respiratory disease. MATERIALS AND METHODS:In this retrospective cohort study, hospitalization rates and emergency admissions of patients before (December 2014-December 2015) and after PR (January 2015-December 2016) were investigated. Patients with chronic respiratory diseases were included. Chronic obstructive pulmonary disease (COPD) patients were classified based on the Global Initiative Chronic Obstructive Pulmonary Disease assessment scheme. PR was applied by three physiotherapists over 8 weeks (2 days/week). Data on patient demographics, clinical and anthropometric data, spirometry, exercise capacity, and quality of life before and after PR were acquired. RESULTS:This study evaluated 51 patients, of whom 76% were men. A total of 37 (73%) COPD patients and 14 (27%) non-COPD patients (7 bronchiectasis, 4 interstitial lung disease, and 3 kyphoscoliosis) were included. The patients exhibited significantly improved incremental shuttle walk test (ISWT) and endurance test scores (p<0.05) after PR. Similar to exercise capacity, the patients exhibited significantly improved Modified Medical Research Council (mMRC) score, St. George's Respiratory Questionnaire (SGRQ), anxiety and depression scores (p<0.05) after PR. In COPD patients, differences in pre- and post-PR ISWT, COPD assessment test, mMRC, and SGRQ scores were statistically significant (p=0.001). The number of emergency admissions and hospitalizations significantly decreased after PR (p=0.001; p=0.001). The post-PR FEV1% of COPD significantly increased (p=0.029). CONCLUSION:Pulmonary rehabilitation leads to an increase in exercise capacity as well as improved quality of life, resulting in a decrease in emergency admissions and hospitalization rates. Considering the cost of hospitalization, it is important to add PR to the management of patients with chronic respiratory diseases, in addition to medical therapy.
