Unrealistic Postsurgical Expectation of Independence Predicts Complex Hospital Discharge.

BACKGROUND: Careful discharge planning for older surgical patients can reduce length of stay, readmission, and cost. We hypothesized that patients who overestimate their self-care ability before surgery are more likely to have complex postoperative discharge planning. MATERIALS AND METHODS: The Vulnerable Elders Surgical Pathways and Outcomes Assessment is a brief preoperative assessment that can identify older (age ≥70) patients with multidimensional geriatric risk, defined by all three of the following: (1) physical or cognitive impairment, (2) living alone, and (3) lack of handicap-accessible home. The Vulnerable Elders Surgical Pathways and Outcomes Assessment also asks a novel postoperative self-care ability question, whether patient can independently provide self-care for several hours after discharge. Classifying patients into four groups based on multidimensional geriatric risk (full versus none or partial) and the self-care ability question (yes or no), we hypothesized those with unrealistic postsurgical expectation of independence (UPSI) (both fully at risk and "yes" to self-care ability question) would be at the increased risk for complex discharge planning. Complex discharge planning was defined as prolonged stay because of nonmedical reasons or multiple changes in discharge plans. RESULTS: In 382 hospitalizations of ≥2 d, 366 had a nonmissing answer to the self-care question; of those 5% had UPSI and 6.3% needed complex discharge planning. The UPSI group was independently associated with greater risk of complex discharge planning compared with the normal group (odds ratio = 4.3 [95% confidence interval, 1.1-16.1]). CONCLUSIONS: Complex discharges were rare, but predictable by preoperative geriatric screening. Patients with UPSI should be targeted for postoperative care planning in advance of surgery.

Analytic morphomics corresponds to functional status in older patients.

BACKGROUND: Older patients account for nearly half of the United States surgical volume, and age alone is insufficient to predict surgical fitness. Various metrics exist for risk stratification, but little work has been done to describe the association between measures. We aimed to determine whether analytic morphomics, a novel objective risk assessment tool, correlates with functional measures currently recommended in the preoperative evaluation of older patients. MATERIALS AND METHODS: We retrospectively identified 184 elective general surgery patients aged >70 y with both a preoperative computed tomography scan and Vulnerable Elderly Surgical Pathways and outcomes Assessment within 90 d of surgery. We used analytic morphomics to calculate trunk muscle size (or total psoas area [TPA]) and univariate logistic regression to assess the relationship between TPA and domains of geriatric function mobility, basic and instrumental activities of daily living (ADLs), and cognitive ability. RESULTS: Greater TPA was inversely correlated with impaired mobility (odds ratio [OR] = 0.46, 95% confidence interval [CI] 0.25-0.85, P = 0.013). Greater TPA was associated with decreased odds of deficit in any basic ADLs (OR = 0.36 per standard deviation unit increase in TPA, 95% CI 0.15-0.87, P <0.03) and any instrumental ADLs (OR = 0.53, 95% CI 0.34-0.81; P <0.005). Finally, patients with larger TPA were less likely to have cognitive difficulty assessed by Mini-Cog scale (OR = 0.55, 95% CI 0.35-0.86, P <0.01). Controlling for age did not change results. CONCLUSIONS: Older surgical candidates with greater trunk muscle size, or greater TPA, are less likely to have physical impairment, cognitive difficulty, or decreased ability to perform daily self-care. Further research linking these assessments to clinical outcomes is needed.

A vertically integrated geriatric curriculum improves medical student knowledge and clinical skills.

The objective of this study was to determine the effect of a vertically integrated curriculum intervention on the geriatric knowledge and performance in clinical skills of third-year medical students. This observational cohort study conducted at the University of Michigan Medical School evaluates the performance of 622 third-year medical students from the graduating class years of 2004 through 2007. An integrated curriculum intervention was developed and implemented for the class of 2006. Its elements included identification and tracking of geriatric learning outcomes in an individualized Web-based student portfolio, integration of geriatric content into preclinical courses, development of a geriatric functional assessment standardized patient instructor, and an experience in a geriatrics clinic during the ambulatory component of the third-year internal medicine clerkship. Medical student performance was assessed on a geriatric knowledge test and during a geriatric functional assessment station administered during an Observed Structured Clinical Examination (OSCE) at the beginning of the fourth year. Student performance on the geriatric functional assessment OSCE station progressively improved from pre-intervention performance (mean performance+/-standard deviation 43+/-15% class of 2005, 62 + 15% class of 2006, 78+/-10% class of 2007; analysis of variance, P<.001). Similarly, student performance on the geriatric knowledge test was significantly better for the classes of 2006 and 2007 than for the class of 2005 (model F ratio=4.72; P<.001). In conclusion, an integrated approach to incorporating new educational geriatric objectives into the medical school curriculum leads to significant improvements in medical student knowledge and in important clinical skills in the functional assessment of older patients.

Development of a standardized patient instructor to teach functional assessment and communication skills to medical students and house officers.

Professional societies have called for increased geriatrics training for all medical students and physicians. A Geriatrics Standardized Patient Instructor (GSPI) was developed in which learners assess the functional status of a patient preparing for hospital discharge. Standardized patients (SPs) rate learners on functional assessment and communication skills, and provide feedback. Seventeen SPs were trained. Correlations of ratings by SPs with ratings by three geriatricians of videotaped encounters indicated good reliability (correlation coefficient = 0.69 and 0.70 for functional assessment and communication skills, respectively). Results from two learner groups illustrated the utility and feasibility of the GSPI. First, 138 house officers in nine specialties experienced the GSPI as a formative evaluation during implementation of new geriatrics curricula. Mean scores+/-standard deviation (on a 100-point scale) for functional assessment and communication skills were 78+/-16 and 86+/-11, respectively. House officers rated the overall experience positively (mean rating (1 = poor, 5 = excellent) 3.9+/-0.8). Second, 171 first-year medical students (M1 s) encountered the GSPI as part of an intense, multimodal educational intervention. Mean scores on functional assessment and communication skills were 93+/-10 and 93+/-7, respectively. Mean overall rating of the experience by M1 s was 4.1+/-0.8. After demonstrated success as a teaching tool in these two groups of learners, the GSPI has been successfully used with second- and third-year (M3) medical students and house officers from a total of 12 specialties and incorporated into multistation Objective Standardized Clinical Examination exercises for incoming house officers and M3 s. Unlike existing diagnosis-oriented SPs, the GSPI can be used to assess and teach geriatrics skills to physician learners across disciplines and levels of training.

A multidisciplinary intervention for reducing readmissions among older adults in a patient-centered medical home.

OBJECTIVES: To evaluate the effectiveness of a multidisciplinary practice model consisting of medical providers, clinical pharmacists, and social workers on reducing 30-day all-cause readmissions. STUDY DESIGN: Retrospective cohort study. METHODS: This study included adults 60 years or older discharged from a large academic medical center. Patients were grouped as either receiving the primary care-based transitional care program (intervention group) or usual care (control group) after an index hospitalization. Only 1 index hospitalization was included per patient. All-cause 30-day readmission rates between propensity score matched study groups were analyzed by intention-to-treat, per protocol, and as-treated methods. Secondary outcomes included time to readmission, subgroup analysis, process measures, and cost avoidance influence of covariates on chance of readmission measured by logistic regression. RESULTS: Over 27 months, 19,169 unique patients had 18,668 index hospitalizations and 572 interventions scheduled after discharge. Among matched subjects, 30-day readmission rates were not significantly different between those scheduled for the intervention and those never scheduled (21% vs 17.3%, respectively; P = .133). However, when those completing the intervention (n = 217) were examined, readmission rates were significantly reduced (11.7% vs 17.3%, respectively; P < .001). Likewise, time to readmission was significantly longer among those receiving the intervention (18 ± 9 days compared with 12 ± 9 days with usual care; P = .015) and potential cost avoidance was observed only when the intervention was completed. CONCLUSIONS: A community-based multidisciplinary transitional care program may reduce hospital readmissions among older adults.

Aging and neural control of the GI tract. II. Neural control of the aging gut: can an old dog learn new tricks?

There has been a dramatic increase in funding available for aging research, primarily due to the fact that answers to questions on aging are likely to have a major impact on the well-being and healthy aging of the world's population for decades to come. The incidence of certain gastrointestinal problems, such as dysphagia and constipation, increases dramatically with age. Changes in gastrointestinal neuromuscular function with aging have been demonstrated in both human and animal models of aging. This article focuses on recent advances in our knowledge of the effects of aging on gastrointestinal function, treatment options, and future opportunities for research.

Diabetic neuropathy: inhibitory G protein dysfunction involves PKC-dependent phosphorylation of Goalpha.

We examined the hypothesis that decreased inhibitory G protein function in diabetic neuropathy is associated with increased protein kinase C (PKC)-dependent phosphorylation of the Goalpha subunit. Streptozotocin-induced diabetic rats were studied between 4 and 8 weeks after onset of diabetes and compared with aged-matched healthy animals as controls. Opioid-mediated inhibition of forskolin-stimulated cyclic AMP was significantly less in dorsal root ganglia (DRGs) from diabetic rats compared with controls. Activation of PKC in DRGs from control rats was associated with a significant decrease in opioid-mediated inhibition of forskolin-stimulated cyclic AMP that was similar to the decrease in inhibition observed in DRGs from diabetic rats. Both basal and PKC-mediated labeling of Goalpha with 32Pi was significantly less in DRGs from diabetic rats, supporting increased endogenous PKC-dependent phosphorylation of Goalpha. Probing of immunoprecipitated Goalpha with an anti-phospho-serine/threonine specific antibody revealed a significant increase in baseline phosphorylation in diabetic DRGs. Activation of PKC produced a significant increase in phosphorylation in control DRGs but no significant increase in Goalpha in diabetic DRGs. Phosphorylation of PKC-alpha was increased, PKC-betaII was unchanged and PKC-delta decreased in diabetic DRGs. These results suggest that diminished inhibitory G protein function observed in DRGs neurons from diabetic rats involves an isoform-specific PKC-dependent pathway.
