OBJECTIVES (1) To determine the relationship of incident delirium during hospitalization with 90-day mortality; (2) to identify potential in-hospital mediators through which delirium increases 90-day mortality. DESIGN Analysis of data from Project Recovery, a controlled clinical trial of a delirium prevention intervention from 1995 to 1998 with follow-up through 2000. SETTING Large academic hospital. PARTICIPANTS Patients ≥70 years-old without delirium at hospital admission who were at intermediate-to-high risk of developing delirium and received usual care only. MEASUREMENTS (1) Incident delirium; (2) potential mediators of delirium on death including use of restraining devices (physical restraints, urinary catheters), development of hospital acquired conditions (HACs) (falls, pressure ulcers), and exposure to other noxious insults (sleep deprivation, acute malnutrition, dehydration, aspiration pneumonia); (3) death within 90 days of admission. RESULTS Among 469 patients, 70 (15%) developed incident delirium. These patients were more likely to experience restraining devices (37% vs. 16%, p<.001), HACs (37% vs. 12%, p<.001), other noxious insults (63% vs. 49%, p=.03), and 90-day mortality (24% vs. 6%, p<.001). The inverse probability weighted hazard of death due to delirium was 4.2 (95% CI=2.8–6.3) in bivariable analyses, increased in a graded manner with additional exposures to restraining devices, HACs, and other noxious insults, and declined by 10.9% after addition of these potential mediator categories, providing evidence of mediation. CONCLUSION Restraining devices, HACs, and additional noxious insults were more frequent among patients with delirium, increased mortality in a graded manner, and were responsible for a significant percentage of the association of delirium with death. Additional efforts to prevent potential downstream mediators through which delirium increases mortality may help to improve outcomes among hospitalized older adults.
Acute Physiology and Chronic Health Evaluation, Sequential Organ Failure Assessment, and Discharge Readiness Scores all have relatively high discrimination for ICU mortality when used continuously; Discharge Readiness Scores tended to have slightly higher area under the receiver operating characteristic curves for each endpoint. These findings validate the use of these models on a population level for continuous risk adjustment in the ICU, although Acute Physiology and Chronic Health Evaluation and Sequential Organ Failure Assessment appear slower to respond to improvements in patient status than Discharge Readiness Scores, and Discharge Readiness Scores may reflect physiologic improvement from interventions, potentially underestimating risk.
ObjectiveTo present our experience in surgical management of urolithiasis in patients after urinary diversion.Patients and MethodsTwenty patients with urolithiasis after urinary diversion received intervention. Percutaneous nephrolithotomy, percutaneous based antegrade ureteroscopy with semi-rigid or flexible ureteroscope, transurethral reservoir lithotripsy, percutaneous pouch lithotripsy and open operation were performed in 8, 3, 2, 6, and 1 patients, respectively. The operative finding and complications were retrospectively collected and analyzed.ResultsThe mean stone size was 4.5±3.1 (range 1.5–11.2) cm. The mean operation time was 82.0±11.5 (range 55–120) min. Eighteen patients were rendered stone free with a clearance of 90%. Complications occurred in 3 patients (15%). Two patients (10%) had postoperative fever greater than 38.5°C, and one patient (5%) suffered urine extravasations from percutaneous tract.ConclusionsThe percutaneous based procedures, including percutaneous nephrolithotomy, antegrade ureteroscopy with semi-rigid ureteroscope or flexible ureteroscope from percutaneous tract, and percutaneous pouch lithotripsy, provides a direct and safe access to the target stones in patients after urinary diversion, and with high stone free rate and minor complications. The surgical management of urolithiasis in patients after urinary diversion requires comprehensive evaluation and individualized consideration depending upon the urinary diversion type, stone location, stone burden, available resource and surgeon experience.
Objectives To examine the relationship between primary diagnoses and mobility impairment and recovery among hospitalized older adults. Design Prospective cohort study. Setting UF Health Shands Hospital, an 852-bed level I trauma center located in Gainesville, Florida. Participants 18,551 older adults (≥65 years) with 29,148 hospitalizations between 1/2009 and 4/2014. Measurements Incident and discharge mobility impairment and recovery were assessed using the Braden activity subscale score that was recorded by the nursing staff at every shift change–approximately three times per day. Primary diagnosis ICD-9 codes were used as predictors and re-categorized by using the Agency for Health Care Research and Quality Clinical Classification Software. Results Out of the 15,498 hospital records where the patient was initially observed to “walk frequently”, 3,186 (20.6%) developed incident mobility impairment (chair-fast or bedfast). Primary diagnoses with a surgical or invasive procedure were the most prevalent (77.2 %) among the hospital observations with incident mobility impairment; otherwise primary diagnoses without surgery were much more associated with discharge mobility impairment (59%). The highest incidence of mobility impairment occurred in patients with heart valve disorders and aortic and peripheral/visceral artery aneurysms (6.24 and 6.05 events per 30 person-days, respectively); septicemia showed the highest incidence rate for mobility limitation at discharge (0.94 events per 30 person-days). Mobility impairment was observed in 13,650 (46.8% of total) records at admission and 5,930 (43.44%) were observed to recover to a state of walking occasionally or frequently. Osteoarthritis and cancer of gastrointestinal organs/peritoneum had the highest incidence rate for mobility recovery (7.68 and 5.63 events per 30 person-days respectively). Conclusions Approximately 1 out of 5 patients who were mobile at admission became significantly impaired during hospitalization. However, about half (43.4%) of patients observed to have mobility impairment at admission recovered during hospitalization. Conditions most associated with mobility impairment and recovery are varied, but older patients hospitalized for septicemia and cardiovascular diseases with surgery (heart valve disorders and aortic/peripheral/visceral artery aneurysms) appear to be at most risk for incident mobility impairment that did not recover at discharge.
Introduction: Mini percutaneous nephrolithotomy (mini-PCNL) and retrograde intrarenal surgery (RIRS) are well-established techniques with little morbidity. The combined use of standard PCNL and the mini-PCNL or the RIRS technique was evaluated and compared to investigate their own role in the management of staghorn calculi in solitary kidney. Materials and Methods: 23 patients received combined standard PCNL and mini-PCNL (group 1), and 22 patients received combined standard PCNL and RIRS (group 2). The treatment results and complications were evaluated and compared. Results: The mean operation time was 128.8 ± 9.1 min in group 1 and 109.8 ± 10.7 min in group 2 (p < 0.001). The decrease in hemoglobin level in group 1 was significantly higher than that in group 2 (3.5 ± 0.6 vs. 2.1 ± 0.5 g/dl, p < 0.001). The final stone-free rate was significantly higher (p = 0.038) in group 2 (90.9%) than in group 1 (65.2%). Conclusions: Combined standard PCNL and RIRS technique can extract the majority of staghorn calculi quickly by PCNL with EMS Lithoclast, and RIRS used simultaneously can reduce the need for multiple tracts and therefore reduce blood loss and potential morbidity related to multiple tracts, shorten the operation time and achieve a high stone-free rate.
Background Age-associated decline in central cholinergic activity makes older adults susceptible to harmful effects of anticholinergic (AC) medications. However, there is an inadequate understanding of association and possible effects of AC drugs on cognition. This cross-sectional study examines the associations of AC medications on cognition among older adults with questionable cognitive impairment (QCI). Methods For this cross-sectional study, we used multicenter database of community dwelling older adults (N=7,351) aged 60+ years with QCI from September 2005 until March 2014 as baseline data. Anticholinergic Drug Scale was used to categorize AC drug load in no, low or moderate/high groups. Individuals with clinical dementia rating-sum of boxes score between 0.5 and 2.5 were identify as having QCI. Cognitive performance was evaluated using Neuropsychological Test Battery. The mean z-scores of neuropsychological tests were grouped into a global cognition score. Results Participants who took AC medications were older, largely female and had higher prevalence of incontinence than those without AC exposure. Global cognition was significantly greater in moderate/high AC group than no AC group (-0.23±0.53 vs. -0.32±0.53). Multivariable linear regression showed that global cognition score among low and moderate/high AC groups, as compared to no AC group, was higher by 0.064 (P=.006 and P=.12, respectively). Conclusions This cross-sectional study indicates that older adults with QCI who were exposed to AC medications might have higher global cognitive scores than those without AC exposure. The observed associations indicate that older adults might experience some beneficial cognitive effects from AC drugs, possibly due to the therapeutic effects of these medications in controlling comorbidities; thus, outweighing their adverse effects on cognition.
