Although measures, such as functional, cognitive, and psychological status, are known to be crucial components of health in older persons, they are not often used in assessing the risk of adverse postoperative outcomes in older adults.To determine the association between measures of physical, cognitive, and psychological function and 1-year mortality in older adults after major surgery.Retrospective analysis of a prospective cohort study of participants 66 years or older who were enrolled in the nationally representative Health and Retirement Study and underwent 1 of 3 types of major surgery.Major surgery, including abdominal aortic aneurysm repair, coronary artery bypass graft, and colectomy.Our outcome was mortality within 1 year of major surgery. Our primary associated factors included functional, cognitive, and psychological factors: dependence in activities of daily living (ADL), dependence in instrumental ADL, inability to walk several blocks, cognitive status, and presence of depression. We adjusted for other demographic and clinical predictors.Of 1341 participants, the mean (SD) participant age was 76 (6) years, 737 (55\%) were women, 99 (7\%) underwent abdominal aortic aneurysm repair, 686 (51\%) coronary artery bypass graft, and 556 (42\%) colectomy; 223 (17\%) died within 1 year of their operation. After adjusting for age, comorbidity burden, surgical type, sex, race/ethnicity, wealth, income, and education, the following measures were significantly associated with 1-year mortality: more than 1 ADL dependence (29\% vs 13\%; adjusted hazard ratio [aHR], 2.76; P = .001), more than 1 instrumental ADL dependence (21\% vs 14\%; aHR, 1.32; P = .05), the inability to walk several blocks (17\% vs 11\%; aHR, 1.64; P = .01), dementia (21\% vs 12\%; aHR, 1.91; P = .03), and depression (19\% vs 12\%; aHR, 1.72; P = .01). The risk of 1-year mortality increased within the increasing risk factors present (0 factors: 10.0\%; 1 factor: 16.2\%; 2 factors: 27.8\%).In this older adult cohort, 223 participants (17\%) who underwent major surgery died within 1 year and poor function, cognition, and psychological well-being were significantly associated with mortality. Measures in function, cognition, and psychological well-being need to be incorporated into the preoperative assessment to enhance surgical decision-making and patient counseling.}, keywords = {Cognition, Mortality, Surgery}, issn = {2168-6254}, doi = {10.1001/jamasurg.2020.0091}, url = {https://jamanetwork.com/journals/jamasurgery/article-abstract/2762522}, author = {Victoria L.

However, data on functional status are seldom collected during routine clinical care in a way that makes them available for clinical use and research. Objectives To validate functional status data that Veterans Affairs (VA) medical centers recently started collecting during routine clinical care, compared to the same data collected in a structured research setting. Design Prospective validation study. Setting Seven VA medical centers that collected complete data on 5 activities of daily living (ADLs) and 8 instrumental activities of daily living (IADLs) from older patients attending primary care appointments. Participants Randomly selected patients aged 75 and older who had new ADL and IADL data collected during a primary care appointment (N = 252). We oversampled patients with ADL dependence and applied these sampling weights to our analyses. Measurements Telephone-based interviews using a validated measure to assess the same 5 ADLs and 8 IADLs. Results Mean age was 83 years, 96\% were male, and 75\% were white. Of 85 participants whom VA data identified as dependent in 1 or more ADLs, 74 (87\%) reported being dependent by interview; of 167 whom VA data identified as independent in ADLs, 149 (89\%) reported being independent. The sample-weighted sensitivity of the VA data for identifying ADL dependence was 45\% (95\% CI, 29\%, 62\%) compared to the reference standard, the specificity was 99\% (95\% CI, 99\%, >99\%), and the positive predictive value was 87\% (95\% CI, 79\%, 93\%). The weighted kappa statistic was 0.55 (95\% CI, 0.41, 0.68) for the agreement between VA data and research-collected data in identifying ADL dependence. Conclusion Overall agreement of VA functional status data with a reference standard was moderate, with fair sensitivity but high specificity and positive predictive value.}, keywords = {Daily activities, Functional status, Veterans}, doi = {10.1371/journal.pone.0178726 Free full text}, url = {http://dx.plos.org/10.1371/journal.pone.0178726}, author = {Rebecca T Brown and Kiya D Komaiko and Shi, Ying and Kathy Z Fung and W John Boscardin and Au-Yeung, Alvin and Tarasovsky, Gary and Jacob, Riya and Michael A Steinman}, editor = {Hernandez-Boussard, Tina} } @article {8678, title = {Rates of Recovery to Pre-Fracture Function in Older Persons with Hip Fracture: an Observational Study.}, journal = {J Gen Intern Med}, volume = {32}, year = {2017}, month = {2017 Feb}, pages = {153-158}, abstract = {

BACKGROUND: Knowledge about expected recovery after hip fracture is essential to help patients and families set realistic expectations and plan for the future.

OBJECTIVES: To determine rates of functional recovery in older adults who sustained a hip fracture based on one{\textquoteright}s previous function.

DESIGN: Observational study.

PARTICIPANTS: We identified subjects who sustained a hip fracture while enrolled in the nationally representative Health and Retirement Study (HRS) using linked Medicare claims. HRS interviews subjects every 2~years. Using information from interviews collected during the interview preceding the fracture and the first interview 6 or more months after the fracture, we determined the proportion of subjects who returned to pre-fracture function.

MAIN MEASURES: Functional outcomes of interest were: (1) ADL dependency, (2) mobility, and (3) stair-climbing ability. We examined baseline characteristics associated with a return to: (1) ADL independence, (2) walking one block, and (3) climbing a flight of stairs.

KEY RESULTS: A total of 733 HRS subjects >=65~years of age sustained a hip fracture (mean age 84 {\textpm} 7~years, 77~\% female). Thirty-one percent returned to pre-fracture ADL function, 34~\% to pre-fracture mobility function, and 41~\% to pre-fracture climbing function. Among those who were ADL independent prior to fracture, 36~\% returned to independence, 27~\% survived but needed ADL assistance, and 37~\% died. Return to ADL independence was less likely for those >=85~years old (26~\% vs. 44~\%), with dementia (8~\% vs. 39~\%), and with a Charlson comorbidity score >2 (23~\% vs. 44~\%). Results were similar for those able to walk a block and for those able to climb a flight of stairs prior to fracture.

CONCLUSIONS: Recovery rates are low, even among those with higher levels of pre-fracture functional status, and are worse for patients who are older, cognitively impaired, and who have multiple comorbidities.

OBJECTIVES: To develop a prediction index for 1-year mortality after hip fracture in older adults that includes predictors from a wide range of domains.

DESIGN: Retrospective cohort study.

SETTINGS: Health and Retirement Study (HRS).

PARTICIPANTS: HRS participants who experienced hip fracture between 1992 and 2010 as identified according to Medicare claims data (N = 857).

MEASUREMENTS: Outcome measure was death within 1 year of hip fracture. Predictor measures were participant demographic characteristics, socioeconomic status, social support, health, geriatric symptoms, and function. Variables independently associated with 1-year mortality were identified, and best-subsets regression was used to identify the final model. The selected variables were weighted to create a risk index. The index was internally validated using bootstrapping to estimate model optimism.

RESULTS: Mean age at time of hip fracture was 84, and 76\% of the participants were women. There were 235 deaths (27\%) during the 1-year follow up. Five predictors of mortality were included in the final model: aged 90 and older (2 points), male sex (2 points), congestive heart failure (2 points), difficulty preparing meals (2 points), and not being able to drive (1 point). The point scores of the index were associated with 1-year mortality, with 0 points predicting 10\% risk and 7 to 9 points predicting 66\% risk. The c-statistic for the final model was 0.73, with an estimated optimism penalty of 0.01, indicating very little evidence of overfitting.

CONCLUSION: The prognostic index combines demographic, comorbidity, and function variables and can be used to differentiate between individuals at low and high risk of 1-year mortality after hip fracture.

BACKGROUND: As our society ages, improving medical care for an older population will be crucial. Discrimination in healthcare may contribute to substandard experiences with the healthcare system, increasing the burden of poor health in older adults. Few studies have focused on the presence of healthcare discrimination and its effects on older adults.

OBJECTIVE: We aimed to examine the relationship between healthcare discrimination and new or worsened disability.

DESIGN: This was a longitudinal analysis of data from the nationally representative Health and Retirement Study administered in 2008 with follow-up through 2012.

PARTICIPANTS: Six thousand and seventeen adults over the age of 50 years (mean age 67 years, 56.3 \% female, 83.1 \% white) were included in this study.

MAIN MEASURES: Healthcare discrimination assessed by a 2008 report of receiving poorer service or treatment than other people by doctors or hospitals (never, less than a year=infrequent; more than once a year=frequent). Outcome was self-report of new or worsened disability by 2012 (difficulty or dependence in any of six activities of daily living). We used a Cox proportional hazards model adjusting for age, race/ethnicity, gender, net worth, education, depression, high blood pressure, diabetes, cancer, lung disease, heart disease, stroke, and healthcare utilization in the past 2 years.

KEY RESULTS: In all, 12.6 \% experienced discrimination infrequently and 5.9 \% frequently. Almost one-third of participants (29 \%) reporting frequent healthcare discrimination developed new or worsened disability over 4 years, compared to 16.8 \% of those who infrequently and 14.7 \% of those who never experienced healthcare discrimination (p < 0.001). In multivariate analyses, compared to no discrimination, frequent healthcare discrimination was associated with new or worsened disability over 4 years (aHR = 1.63, 95 \% CI 1.16-2.27).

CONCLUSIONS: One out of five adults over the age of 50 years experiences discrimination in healthcare settings. One in 17 experience frequent healthcare discrimination, and this is associated with new or worsened disability by 4 years. Future research should focus on the mechanisms by which healthcare discrimination influences disability in older adults to promote better health outcomes for an aging population.
