Functional recovery of older people with hip fracture: does malnutrition make a difference?

Aim To report a study of the effects of protein‐energy malnutrition on the functional recovery of older people with hip fracture who participated in an interdisciplinary intervention. Background It is not clear whether protein‐energy malnutrition is associated with worse functional outcomes or it affects the interdisciplinary intervention program on the functional recovery of older people with hip fracture. Design A randomized experimental design. Methods Data were collected between 2002–2006 from older people with hip fracture ( N  = 162) in Taiwan. The generalized estimating equations approach was used to evaluate the effect of malnutrition on the functional recovery of older people with hip fracture. Results The majority of older patients with hip fracture were malnourished (48/80, 60% in the experimental group vs. 55/82, 67% in the control group) prior to hospital discharge. The results of the generalized estimating equations analysis demonstrated that subjects suffering from protein‐energy malnutrition prior to hospital discharge appeared to have significantly worse performance trajectories for their activities of daily living, instrumental activities of daily living, and recovery of walking ability compared with those without protein‐energy malnutrition. In addition, it was found that the intervention is more effective on the performance of activities of daily living and recovery of walking ability in malnourished patients than in non‐malnourished patients. Conclusion Healthcare providers should develop a nutritional assessment/management system in their interdisciplinary intervention program to improve the functional recovery of older people with hip fracture.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/99041/1/jan12027.pd

Diabetes and Health Outcomes Among Older Taiwanese with Hip Fracture

Abstract Objective: Hip fracture tremendously impacts functional abilities for the elderly with high morbidity and mortality; recovery is compromised by co-morbidities. Diabetes mellitus is a common co-morbidity for the aging population, but little is known about the influence of diabetes on outcomes of the Asian elderly with hip fracture. Research Design and Methods: This study was a secondary analysis of data on 242 community-dwelling elders with hip fracture from three previous longitudinal studies. Sixty-one cases (25.2%) had diabetes. Outcomes were measured by the Chinese Barthel Index, Medical Outcomes Study Short Form-36 Taiwan version, and analyzed by the generalized estimating equation approach to examine how diabetes influenced hip-fractured elders' mortality, service utilization, mobility, daily activities, and health-related quality of life during the first 12 months after postsurgical discharge in Taiwan. Results: Hip-fractured elderly with diabetes had a significantly higher mortality rate (22.6% vs. 10.3%, p=0.03) during the first year following discharge, and significantly higher readmission rate (10.0% vs. 2.5%, p=0.04) from the first to third month following discharge than those without diabetes. After controlling for covariates, elderly participants without diabetes had an overall 2.2 times (confidence interval [CI]=1.15?4.21) greater odds of recovery in walking ability and better reported general health (?=9.33; p=0.01) and physical functioning (?=7.26; p=0.02) than those with diabetes during the first year after discharge. Conclusions: Diabetes negatively influenced outcomes of elderly patients with hip fracture. The results may provide a reference for developing interventions for hip-fractured elders with diabetes.Peer Reviewedhttp://deepblue.lib.umich.edu/bitstream/2027.42/98472/1/rej%2E2011%2E1308.pd

Effects of interventions on trajectories of health-related quality of life among older patients with hip fracture: a prospective randomized controlled trial

Abstract Background Health-related quality of life (HRQoL) has been used to assess subjects’ prognosis and recovery following hip fracture. However, evidence is mixed regarding the effectiveness of interventions to improve HRQoL of elders with hip fracture. The purposes of this study were to identify distinct HRQoL trajectories and to evaluate the effects of two care models on these trajectories over 12 months following hip-fracture surgery. Methods For this secondary analysis, data came from a randomized controlled trial of subjects with hip fracture receiving three treatment care models: interdisciplinary care (n = 97), comprehensive care (n = 91), and usual care (n = 93). Interdisciplinary care consisted of geriatric consultation, discharge planning, and 4 months of in-home rehabilitation. Comprehensive care consisted of interdisciplinary care plus management of malnutrition and depressive symptoms, fall prevention, and 12 months of in-home rehabilitation. Usual care included only in-hospital rehabilitation and occasional discharge planning, without geriatric consultation and in-home rehabilitation. Mental and physical HRQoL were measured at 1, 3, 6, and 12 months after discharge by the physical component summary scale (PCS) and mental component summary scale (MCS), respectively, of the Medical Outcomes Study Short Form 36, Taiwan version. Latent class growth modeling was used to identify PCS and MCS trajectories and to evaluate how they were affected by the interdisciplinary and comprehensive care models. Results We identified three quadratic PCS trajectories: poor PCS (n = 103, 36.6 %), moderate PCS (n = 96, 34.2 %), and good PCS (n = 82, 29.2 %). In contrast, we found three linear MCS trajectories: poor MCS (n = 39, 13.9 %), moderate MCS (n = 84, 29.9 %), and good MCS (n = 158, 56.2 %). Subjects in the comprehensive care and interdisciplinary care groups were more likely to experience a good PCS trajectory (b = 0.99, odds ratio [OR] = 2.69, confidence interval [CI] = 7.24–1.00, p = 0.049, and b = 1.32, OR = 3.75, CI = 10.53–1.33, p = 0.012, respectively) than those who received usual care. However, neither care model improved MCS. Conclusions The interdisciplinary and comprehensive care models improved recovery from hip fracture by increasing subjects’ odds for following a trajectory of good physical functioning after hospitalization.

The relationship between preoperative American Society of Anesthesiologists Physical Status Classification scores and functional recovery following hip-fracture surgery

Abstract Background Little is known about the relationship of the American Society of Anesthesiologists Physical Status Classification scores (ASA scores) on patient outcomes following hip fracture surgery in Asian countries. Therefore, this study explored the association of patients’ preoperative ASA scores on trajectories of recovery in physical functioning and health outcomes during the first year following postoperative discharge for older adults with hip-fracture surgery in Taiwan. Methods The data for this study was generated from three prior studies. Participants (N = 226) were older hip-fracture patients from an observational study (n = 86) and two clinical trials (n = 61 and n = 79). Participants were recruited from the trauma wards of one medical center in northern Taiwan and data was collected prior to discharge and at 1, 3, 6, and 12 months after hospital discharge. Participants were grouped as ASA class 1–2 (50.5%; ASA Class 1, n = 7; ASA Class 2, n = 107) and ASA class 3 (49.5%, n = 112). Measures for mortality, service utilization, activities of daily living (ADL), measured by the Chinese Barthel Index, and health related quality of life, measured by Medical Outcomes Study Short Form-36, were assessed for the two groups. Generalized estimating equations (GEE) were used to analyze the changes over time for the two groups. Results During the first year following hip-fracture surgery, ASA class 1–2 participants had significantly fewer rehospitalizations (6%, p = .02) and better scores for mental health (mean = 70.29, standard deviation = 19.03) at 6- and 12-months following discharge than those classified as ASA 3. In addition, recovery of walking ability (70%, p = .001) and general health (adjusted mean = 58.31, p = .003) was also significantly better than ASA 3 participants. Conclusions There was a significant association of hip-fracture patients classified as ASA 1–2 with better recovery and service utilization during the first year following surgery. Interventions for hip fractured patients with high ASA scores should be developed to improve recovery and quality of life.https://deepblue.lib.umich.edu/bitstream/2027.42/138818/1/12891_2017_Article_1768.pd

An interdisciplinary intervention for older Taiwanese patients after surgery for hip fracture improves health-related quality of life

Abstract Background The effects of intervention programs on health-related quality of life (HRQOL) of patients with hip fracture have not been well studied. We hypothesized that older patients with hip fracture who received our interdisciplinary intervention program would have better HRQOL than those who did not. Methods A randomized experimental design was used. Older patients with hip fracture (N = 162), 60 to 98 years old, from a medical center in northern Taiwan were randomly assigned to an experimental (n = 80) or control (n = 82) group. HRQOL was measured by the SF-36 Taiwan version at 1, 3, 6, and 12 months after discharge. Results The experimental group had significantly better overall outcomes in bodily pain (β = 9.38, p = 0.002), vitality (β = 9.40, p < 0.001), mental health (β = 8.16, p = 0.004), physical function (β = 16.01, p < 0.001), and role physical (β = 22.66, p < 0.001) than the control group at any time point during the first year after discharge. Physical-related health outcomes (physical functioning, role physical, and vitality) had larger treatment effects than emotional/mental- and social functioning-related health outcomes. Conclusions This interdisciplinary intervention program may improve health outcomes of elders with hip fracture. Our results may provide a reference for health care providers in countries using similar programs with Chinese/Taiwanese immigrant populations.

A Randomized Placebo-Controlled Trial of Varenicline for Smoking Cessation Allowing Flexible Quit Dates

Introduction: Current smoking cessation guidelines recommend setting a quit date prior to starting pharmacotherapy. However, providing flexibility in the date of quitting may be more acceptable to some smokers. The objective of this study was to compare varenicline 1 mg twice daily (b.i.d.) with placebo in subjects using a flexible quit date paradigm after starting medication. Methods: In this double-blind, randomized, placebo-controlled international study, smokers of ≥10 cigarettes/day, aged 18-75 years, and who were motivated to quit were randomized (3:1) to receive varenicline 1 mg b.i.d. or placebo for 12 weeks. Subjects were followed up through Week 24. Subjects were instructed to quit between Days 8 and 35 after starting medication. The primary endpoint was carbon monoxide-confirmed continuous abstinence during Weeks 9-12, and a key secondary endpoint was continuous abstinence during Weeks 9-24. Results: Overall, 493 subjects were randomized to varenicline and 166 to placebo. Continuous abstinence was higher for varenicline than for placebo subjects at the end of treatment (Weeks 9-12: 53.1% vs. 19.3%; odds ratio [OR] 5.9; 95% CI, 3.7-9.4; p < .0001) and through 24 weeks follow-up (Weeks 9-24: 34.7% vs. 12.7%; OR 4.4; 95% CI, 2.6-7.5; p < .0001). Serious adverse events occurred in 1.2% varenicline (none were psychiatric) and 0.6% placebo subjects. Fewer varenicline than placebo subjects reported depression-related adverse events (2.3% vs. 6.7%, respectively). Conclusions: Varenicline 1 mg b.i.d. using a flexible quit date paradigm had similar efficacy and safety compared with previous fixed quit date studies. © The Author 2011.

Computed tomography indices and criteria for the prediction of esophageal variceal bleeding in survivors of biliary atresia awaiting liver transplantation

About 20% of biliary atresia (BA) survivors have attacks of esophageal variceal bleeding. We propose a method to evaluate the risk of esophageal variceal bleeding (EVB) using noninvasive indices by multislice computed tomography (CT). We reviewed 31 potential living-related liver recipients aged 99–5314 days (mean, 1474 days) who underwent CT examinations using a 64-slice multislice CT scanner. Of the 31 patients, 19 patients (Group A) with fecal occult blood had EVB on esophagogastroduodenoscopy, the rest belonged to Group B. Splenic diameters (mm) were divided by body heights (m) and platelet counts (1000/mm3) to produce standardized ratios of transverse splenic length/body height/platelet count (SLHPR). The transverse diameters of paraesophageal veins (PVs) and perigastric veins (PGVs) were measured adjacent to the lower thoracic esophagus and within the lesser sac, respectively. According to a receiver operating characteristic curve analysis, the SLHPRs (r = 0.833), transverse PV (r = 0.957), and PGV (r = 0.987) diameters were better predictors of EVB than demographic and laboratory variables. However, the transverse diameters of PGVs and PVs were the most accurate predictors of the EVB. For candidates awaiting liver transplantation, screening by noninvasive SLHPR and the transverse diameters of PGVs and PVs by CT may help to identify BA patients with a high risk of EVB
