Relationship Between Distressing Symptoms and Changes in Disability After Major Surgery Among Community-living Older Persons.

OBJECTIVES: To evaluate the relationship between distressing symptoms and changes in disability after major surgery and to determine whether this relationship differs according to the timing of surgery (nonelective vs elective), sex, multimorbidity, and socioeconomic disadvantage. BACKGROUND: Major surgery is a common and serious health event that has pronounced deleterious effects on both distressing symptoms and functional outcomes in older persons. METHODS: From a cohort of 754 community-living persons, aged 70 or older, 392 admissions for major surgery were identified from 283 participants who were discharged from the hospital. The occurrence of 15 distressing symptoms and disability in 13 activities were assessed monthly for up to 6 months after major surgery. RESULTS: Over the 6-month follow-up period, each unit increase in the number of distressing symptoms was associated with a 6.4% increase in the number of disabilities [adjusted rate ratio (RR): 1.064; 95% CI: 1.053, 1.074]. The corresponding increases were 4.0% (adjusted RR: 1.040; 95% CI: 1.030, 1.050) and 8.3% (adjusted RR: 1.083; 95% CI: 1.066, 1.101) for nonelective and elective surgeries. Based on exposure to multiple (ie, 2 or more) distressing symptoms, the adjusted RRs (95% CI) were 1.43 (1.35, 1.50), 1.24 (1.17, 1.31), and 1.61 (1.48, 1.75) for all, nonelective, and elective surgeries. Statistically significant associations were observed for each of the other subgroups with the exception of individual-level socioeconomic disadvantage for the number of distressing symptoms. CONCLUSIONS: Distressing symptoms are independently associated with worsening disability, providing a potential target for improving functional outcomes after major surgery.

Association Between Restricting Symptoms and Disability After Critical Illness Among Older Adults.

OBJECTIVES: Older adults who survive critical illness are at risk for increased disability, limiting their independence and quality of life. We sought to evaluate whether the occurrence of symptoms that restrict activity, that is, restricting symptoms, is associated with increased disability following an ICU hospitalization. DESIGN: Prospective longitudinal study of community-living adults 70 years old or older who were interviewed monthly between 1998 and 2018. SETTING: South Central Connecticut, United States. PATIENTS: Two hundred fifty-one ICU admissions from 202 participants who were discharged alive from the hospital. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Occurrence of 15 restricting symptoms (operationalized as number of symptoms and presence of ≥ 2 symptoms) and disability in activities of daily living, instrumental activities of daily living, and mobility was ascertained during monthly interviews throughout the study period. We constructed multivariable Poisson regression models to evaluate the association between post-ICU restricting symptoms and subsequent disability over the 6 months following ICU hospitalization, adjusting for known risk factors for post-ICU disability including pre-ICU disability, frailty, cognitive impairment, mechanical ventilation, and ICU length of stay. The mean age of participants was 83.5 years (sd, 5.6 yr); 57% were female. Over the 6 months following ICU hospitalization, each unit increase in the number of restricting symptoms was associated with a 5% increase in the number of disabilities (adjusted rate ratio, 1.05; 95% CI, 1.04-1.06). The presence of greater than or equal to 2 restricting symptoms was associated with a 29% greater number of disabilities over the 6 months following ICU hospitalization as compared with less than 2 symptoms (adjusted rate ratio, 1.29; 95% CI, 1.22-1.36). CONCLUSIONS: In this longitudinal cohort of community-living older adults, symptoms restricting activity were independently associated with increased disability after ICU hospitalization. These findings suggest that management of restricting symptoms may enhance functional recovery among older ICU survivors.

Changes in Restricting Symptoms after Critical Illness among Community-Living Older Adults.

Rationale: Survivors of critical illness have multiple symptoms, but how restricting symptoms change after critical illness and whether these changes differ among vulnerable subgroups is unknown. Objectives: To evaluate changes in restricting symptoms over the six months after critical illness among older adults and to determine whether these changes differ by sex, multimorbidity, and individual- and neighborhood-level socioeconomic disadvantage. Methods: From a prospective longitudinal study of 754 community-living adults ⩾70 years old interviewed monthly (1998-2018), we identified 233 admissions from 193 participants to the ICU. The occurrence of 15 restricting symptoms, defined as those leading to restricted activity, were ascertained during interviews in the month before ICU admission (baseline) and each of the six months after hospital discharge. Measurements and Main Results: The occurrence and number of restricting symptoms increased more than threefold in the six months after a critical illness hospitalization (adjusted rate ratio [95% confidence interval], 3.1 [2.1-4.6] and 3.3 [2.1-5.3], respectively), relative to baseline. These increases were largest in the first month after hospitalization (adjusted rate ratio [95% confidence interval], 5.3 [3.8-7.3] and 5.4 [3.9-7.5], respectively] before declining and becoming nonsignificant in the third month. Increases in restricting symptoms did not differ significantly by sex, multimorbidity, or individual- or neighborhood-level socioeconomic disadvantage. Conclusions: Restricting symptoms increase substantially after a critical illness before returning to baseline three months after hospital discharge. Our findings highlight the need to incorporate symptom management into post-ICU care and for further investigation into whether addressing restricting symptoms can improve quality of life and functional recovery among older ICU survivors.

Factors Associated With Days Away From Home in the Year After Major Surgery Among Community-living Older Persons.

OBJECTIVE: To identify the factors associated with days away from home in the year after hospital discharge for major surgery. BACKGROUND: Relatively little is known about which older persons are susceptible to spending a disproportionate amount of time in hospitals and other health care facilities after major surgery. METHODS: From a cohort of 754 community-living persons, aged 70+ years, 394 admissions for major surgery were identified from 289 participants who were discharged from the hospital. Candidate risk factors were assessed every 18 months. Days away from home were calculated as the number of days spent in a health care facility. RESULTS: In the year after major surgery, the mean (SD) and median (interquartile range) number of days away from home were 52.0 (92.2) and 15 (0-51). In multivariable analysis, 5 factors were independently associated with the number of days away from home: age 85 years and older, low score on the Short Physical Performance Battery, low peak expiratory flow, low functional self-efficacy, and musculoskeletal surgery. Based on the presence versus absence of these factors, the absolute mean differences in the number of days away from home ranged from 31.2 for age 85 years and older to 53.5 for low functional self-efficacy. CONCLUSIONS: The 5 independent risk factors can be used to identify older persons who are particularly susceptible to spending a disproportionate amount of time away from home after major surgery, and a subset of these factors can also serve as targets for interventions to improve quality of life by reducing time spent in hospitals and other health care facilities.

Functional Effects of Intervening Illnesses and Injuries After Hospitalization for Major Surgery in Community-living Older Persons.

OBJECTIVE: To evaluate the functional effects of intervening illnesses and injuries, that is, events, in the year after major surgery. BACKGROUND: Intervening events have pronounced deleterious effects on functional status in older persons, but have not been carefully evaluated after major surgery. METHODS: From a cohort of 754 community-living persons, aged 70+ years, 317 admissions for major surgery were identified from 244 participants who were discharged from the hospital. Functional status (13 activities) and exposure to intervening hospitalizations, emergency department (ED) visits, and restricted activity were assessed each month. Comprehensive assessments (for covariates) were completed every 18 months. RESULTS: In the year after major surgery, exposure rates (95% CI) per 100-person months to hospitalizations, ED visits, and restricted activity were 10.0 (8.0-12.5), 3.9 (2.8-5.4), and 12.3 (10.2-14.8) for functional recovery and 7.2 (6.1-8.5), 2.5 (1.9-3.2), 11.2 (9.8-12.9) for functional decline. Each of the 3 intervening events were independently associated with reduced recovery, with adjusted hazard ratios (95% CI) of 0.20 (0.09-0.47), 0.35 (0.15-0.81), and 0.57 (0.36-0.90) for hospitalizations, ED visits, and restricted activity. For functional decline, the corresponding odds ratios (95% CI) were 5.68 (3.87-8.33), 1.90 (1.13-3.20), and 1.30 (0.96-1.75). The effect sizes for hospitalizations and ED visits were larger than those for the covariates. CONCLUSIONS: Intervening illnesses/injuries are common in the year after major surgery, and those leading to hospitalization and ED visit are strongly associated with adverse functional outcomes, with effect sizes larger than those of traditional risk factors.

Functional Effects of Intervening Illnesses and Injuries After Critical Illness in Older Persons.

OBJECTIVES: Intervening illnesses and injuries have pronounced deleterious effects on functional status in older persons, but have not been carefully evaluated after critical illness. We set out to evaluate the functional effects of intervening illnesses and injuries in the year after critical illness. DESIGN: Prospective longitudinal study of 754 nondisabled community-living persons, 70 years old or older. SETTING: Greater New Haven, CT, from March 1998 to December 2018. PATIENTS: The analytic sample included 250 ICU admissions from 209 community-living participants who were discharged from the hospital. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Functional status (13 activities) and exposure to intervening illnesses and injuries leading to hospitalization, emergency department visit, or restricted activity were assessed each month. Comprehensive assessments (for covariates) were completed every 18 months. In the year after critical illness, recovery of premorbid function was observed for 169 of the ICU admissions (67.6%), and the mean (sd) number of episodes of functional decline (from 1 mo to the next) was 2.2 (1.6). The adjusted hazard ratios (95% CI) for recovery were 0.18 (0.09-0.39), 0.46 (0.17-1.26), and 0.75 (0.48-1.18) for intervening hospitalizations, emergency department visits, and restricted activity, respectively. For functional decline, the corresponding odds ratios (95% CI) were 2.06 (1.56-2.73), 1.78 (1.12-2.83), and 1.25 (0.92-1.69). The effect sizes for hospitalization and emergency department visit were larger than those for any of the covariates. CONCLUSIONS: In the year after critical illness, intervening illnesses and injuries leading to hospitalization and emergency department visit are strongly associated with adverse functional outcomes, with effect sizes larger than those of traditional risk factors. To improve functional outcomes, more aggressive efforts will be needed to prevent and manage intervening illnesses and injuries after critical illness.

Factors Associated With Functional Recovery Among Older Survivors of Major Surgery.

OBJECTIVE: The objectives of the current study were 2-fold: first, to evaluate the incidence and time to recovery of premorbid function within 6 months of major surgery and second, to identify factors associated with functional recovery among older persons who survive a major surgery with increased disability. BACKGROUND: Most older persons would not choose a surgical treatment resulting in persistently increased postsurgical disability, even if survival was assured. Potential predictors of functional recovery after major surgery have, however, not been well-studied among geriatric patients. METHODS: It is a prospective longitudinal study of 754 community-living persons 70 years or older. The analytic sample included 266 person-admissions in which participants survived major surgery with increased disability and were monitored on a monthly basis for 6 months. RESULTS: Of the 266 person-admissions assessed, 174 (65.4%) recovered to their presurgical level of function, with median time to recovery of 2 months (interquartile range, 1-3), whereas 16 (6.0%) died. Two factors were significantly associated with an increased likelihood of functional recovery: being nonfrail (hazard ratio 1.60; 95% confidence interval 1.03-2.51; P = 0.038) and having elective surgery (hazard ratio 1.72; 95% confidence interval 1.14-2.59; P = 0.009). Three factors were associated with a reduced likelihood of functional recovery: hearing impairment, greater increase in postsurgical disability in the month after hospital discharge, and years of education. CONCLUSIONS: Among older persons, nonfrailty and elective surgery were positively associated with functional recovery, whereas hearing impairment, greater increases in postsurgical disability, and years of education were associated with higher risk of protracted disability.

Functional Trajectories Before and After Major Surgery in Older Adults.

OBJECTIVES: We hypothesized that distinct sets of functional trajectories can be identified in the year before and after major surgery, with unique transition probabilities from pre to postsurgical functional trajectories, and that outcomes would be better among participants undergoing elective versus nonelective surgery. BACKGROUND: Major surgery is common and can be highly morbid in older persons. The relationship between the course of disability (ie, functional trajectory) before and after surgery in older adults has not been well-studied for most operations. METHODS: Prospective cohort study of 754 community-living persons 70 years or older. The analytic sample included 250 participants who underwent their first major surgery during the study period. RESULTS: Before surgery, 4 functional trajectories were identified: no disability (n = 60, 24.0%), and mild (n = 84, 33.6%), moderate (n = 73, 29.2%), and severe (n = 33, 13.2%) disability. After surgery, 4 functional trajectories were identified: rapid (n = 39, 15.6%), gradual (n = 76, 30.4%), partial (n = 70, 28.0%), and little (n = 57, 22.8%) improvement. Rapid improvement was seen for n = 31 (51.7%) participants with no disability before surgery, but was uncommon among those with mild disability (n = 8, 9.5%) and was not observed in the moderate and severe trajectory groups. For participants with mild to moderate disability before surgery, gradual improvement (n = 46, 54.8%) and partial improvement (n = 36, 49.3%) were most common. Most participants with severe disability (n = 27, 81.8%) before surgery exhibited little improvement. Outcomes were better for participants undergoing elective versus nonelective surgery. CONCLUSIONS: Functional prognosis in the year after major surgery is highly dependent on premorbid function.

Factors Associated with Functional Recovery among Older Intensive Care Unit Survivors.

RATIONALE: Most of the 1.4 million older adults who survive the intensive care unit (ICU) annually in the United States face increased disability, but little is known about those who achieve functional recovery. OBJECTIVES: Our objectives were twofold: to evaluate the incidence and time to recovery of premorbid function within 6 months of a critical illness and to identify independent predictors of functional recovery among older ICU survivors. METHODS: Potential participants included 754 persons aged 70 years or older who were evaluated monthly in 13 functional activities (1998-2012). The analytic sample included 218 ICU admissions from 186 ICU survivors. Functional recovery was defined as returning to a disability count less than or equal to the pre-ICU disability count within 6 months. Twenty-one potential predictors were evaluated for their associations with recovery. MEASUREMENTS AND MAIN RESULTS: Functional recovery was observed for 114 (52.3%) of the 218 admissions. In multivariable analysis, higher body mass index (hazard ratio [HR], 1.07; 95% confidence interval [CI], 1.03-1.12) and greater functional self-efficacy (HR, 1.05; 95% CI, 1.02-1.08), a measure of confidence in performing various activities, were associated with recovery, whereas pre-ICU impairment in hearing (HR, 0.38; 95% CI, 0.22-0.66) and vision (HR, 0.59; 95% CI, 0.37-0.95) were associated with a lack of recovery. CONCLUSIONS: Among older adults who survived an ICU admission with increased disability, pre-ICU hearing and vision impairment were strongly associated with poor functional recovery within 6 months, whereas higher body mass index and functional self-efficacy were associated with recovery. Future research is needed to evaluate whether interventions targeting these factors improve functional outcomes among older ICU survivors.

Functional trajectories in the year before hospice.

PURPOSE: We undertook a study to identify distinct functional trajectories in the year before hospice, to determine how patients with these trajectories differ according to demographic characteristics and hospice diagnosis, and to evaluate the association between these trajectories and subsequent outcomes. METHODS: From an ongoing cohort study of 754 community-living persons aged 70 years or older, we evaluated data on 213 persons who were subsequently enrolled in hospice from March 1998 to December 2011. Disability in 13 basic, instrumental, and mobility activities was assessed during monthly telephone interviews through June 2012. RESULTS: In the year before hospice, we identified 5 clinically distinct functional trajectories, representing worsening cumulative burden of disability: late decline (10.8%), accelerated (10.8%), moderate (21.1%), progressively severe (24.9%), and persistently severe (32.4%). Participants with a cancer diagnosis (34.7%) had the most favorable functional trajectories (ie, lowest burden of disability), whereas those with neurodegenerative disease (21.1%) had the worst. Median survival in hospice was only 14 days and did not differ significantly by functional trajectory. Compared with participants in the persistently severe trajectory, those in the moderate trajectory had the highest likelihood of surviving and being independent in at least 1 activity in the month after hospice admission (adjusted odds ratio = 5.5; 95% CI, 1.9-35.9). CONCLUSIONS: The course of disability in the year before hospice differs greatly among older persons but is particularly poor among those with neurodegenerative disease. Late admission to hospice (as shown by the short survival), coupled with high levels of severe disability before hospice, highlight potential unmet palliative care needs for many older persons at the end of life.

Comparison of alternate scoring of variables on the performance of the frailty index.

BACKGROUND: The frailty index (FI) is used to measure the health status of ageing individuals. An FI is constructed as the proportion of deficits present in an individual out of the total number of age-related health variables considered. The purpose of this study was to systematically assess whether dichotomizing deficits included in an FI affects the information value of the whole index. METHODS: Secondary analysis of three population-based longitudinal studies of community dwelling individuals: Nova Scotia Health Survey (NSHS, n = 3227 aged 18+), Survey of Health, Ageing and Retirement in Europe (SHARE, n = 37546 aged 50+), and Yale Precipitating Events Project (Yale-PEP, n = 754 aged 70+). For each dataset, we constructed two FIs from baseline data using the deficit accumulation approach. In each dataset, both FIs included the same variables (23 in NSHS, 70 in SHARE, 33 in Yale-PEP). One FI was constructed with only dichotomous values (marking presence or absence of a deficit); in the other FI, as many variables as possible were coded as ordinal (graded severity of a deficit). Participants in each study were followed for different durations (NSHS: 10 years, SHARE: 5 years, Yale PEP: 12 years). RESULTS: Within each dataset, the difference in mean scores between the ordinal and dichotomous-only FIs ranged from 0 to 1.5 deficits. Their ability to predict mortality was identical; their absolute difference in area under the ROC curve ranged from 0.00 to 0.02, and their absolute difference between Cox Hazard Ratios ranged from 0.001 to 0.009. CONCLUSIONS: Analyses from three diverse datasets suggest that variables included in an FI can be coded either as dichotomous or ordinal, with negligible impact on the performance of the index in predicting mortality.

Changes in neighborhood disadvantage over the course of 22 years among community-living older persons.

BACKGROUND: Among older persons, neighborhood disadvantage is a granular and increasingly used social determinant of health and functional well-being. The frequency of transitions into or out of a disadvantaged neighborhood over time is not known. These transitions may occur when a person moves from one location to another or when the Neighborhood Atlas, the data source for the area deprivation index (ADI) that is used to identify disadvantaged neighborhoods at the census-block level, is updated. METHODS: From a prospective longitudinal study of community-living persons, aged 70 years or older in South Central Connecticut, neighborhood disadvantage was ascertained every 18 months for 22 years (from March 1998 to March 2020). ADI scores higher than the 80th state percentile were used to distinguish neighborhoods that were disadvantaged (81-100) from those that were not (1-80). RESULTS: At baseline, 205 (29.3%) of the 699 participants were living in a disadvantaged neighborhood. Changes in neighborhood disadvantage during 14 consecutive 18-month intervals were relatively uncommon, ranging from 1.5% to 11.8%. Nearly 80% of participants had no change in neighborhood disadvantage and less than 4% had more than one change over a median follow-up of more than 9 years. Overall, the rate of transitions into or out of neighborhood disadvantage was only 2.7 per 100 person-years. These transitions were most common when the Neighborhood Atlas was updated (2013, 2015, 2018, and 2020). Comparable results were observed when decile changes in ADI scores during the 18-month intervals were evaluated. CONCLUSIONS: In longitudinal studies of older persons with extended follow-up, it may not be necessary to update information on disadvantaged neighborhoods in circumstances when it is possible, and the degree of misclassification of neighborhood disadvantage should be relatively low in circumstances when updated information cannot be obtained.

Association of injurious falls with disability outcomes and nursing home admissions in community-living older persons.

Little is known about the deleterious effects of injurious falls relative to those of other disabling conditions or whether these effects are driven largely by hip fractures. From a cohort of 754 community-living elders of New Haven, Connecticut, we matched 122 hospitalizations for an injurious fall (59 hip-fracture and 63 other fall-related injuries) to 241 non-fall-related hospitalizations. Participants (mean age: 85.7 years) were evaluated monthly for disability in 13 activities and admission to a nursing home from 1998 to 2010. For both hip-fracture and other fall-related injuries, the disability scores were significantly greater during each of the first 6 months after hospitalization than for the non-fall-related admissions, with adjusted risk ratios at 6 months of 1.5 (95% confidence interval (CI): 1.3, 1.7) for hip fracture and 1.4 (95% CI: 1.2, 1.6) for other fall-related injuries. The likelihood of having a long-term nursing home admission was considerably greater after hospitalization for a hip fracture and other fall-related injury than for a non-fall-related reason, with adjusted odds ratios of 3.3 (95% CI: 1.3, 8.3) and 3.2 (95% CI: 1.3, 7.8), respectively. Relative to other conditions leading to hospitalization, hip-fracture and other fall-related injuries are associated with worse disability outcomes and a higher likelihood of long-term nursing home admissions.

Trajectories of disability in the last year of life.

BACKGROUND: Despite the importance of functional status to older persons and their families, little is known about the course of disability at the end of life. METHODS: We evaluated data on 383 decedents from a longitudinal study involving 754 community-dwelling older persons. None of the subjects had disability in essential activities of daily living at the beginning of the study, and the level of disability was ascertained during monthly interviews for more than 10 years. Information on the conditions leading to death was obtained from death certificates and comprehensive assessments that were completed at 18-month intervals after the baseline assessment. RESULTS: In the last year of life, five distinct trajectories were identified, from no disability to the most severe disability: 65 subjects had no disability (17.0%), 76 had catastrophic disability (19.8%), 67 had accelerated disability (17.5%), 91 had progressive disability (23.8%), and 84 had persistently severe disability (21.9%). The most common condition leading to death was frailty (in 107 subjects [27.9%]), followed by organ failure (in 82 subjects [21.4%]), cancer (in 74 subjects [19.3%]), other causes (in 57 subjects [14.9%]), advanced dementia (in 53 subjects [13.8%]), and sudden death (in 10 subjects [2.6%]). When the distribution of the disability trajectories was evaluated according to the conditions leading to death, a predominant trajectory was observed only for subjects who died from advanced dementia (67.9% of these subjects had a trajectory of persistently severe disability) and sudden death (50.0% of these subjects had no disability). For the four other conditions leading to death, no more than 34% of the subjects had any of the disability trajectories. The distribution of disability trajectories was particularly heterogeneous among the subjects with organ failure (from 12.2 to 32.9% of the subjects followed a specific trajectory) and frailty (from 14.0 to 27.1% of the subjects followed a specific trajectory). CONCLUSIONS: In most of the decedents, the course of disability in the last year of life did not follow a predictable pattern based on the condition leading to death.

Risk factors and precipitants of long-term disability in community mobility: a cohort study of older persons.

BACKGROUND: Relatively little is known about why older persons develop long-term disability in community mobility. OBJECTIVE: To identify the risk factors and precipitants for long-term disability in walking a quarter mile and driving a car. DESIGN: Prospective cohort study from March 1998 to December 2009. SETTING: Greater New Haven, Connecticut. PARTICIPANTS: 641 persons, aged 70 years or older, who were active drivers or nondisabled in walking a quarter mile. Persons who were physically frail were oversampled. MEASUREMENTS: Candidate risk factors were assessed every 18 months. Disability in community mobility and exposure to potential precipitants, including illnesses or injuries leading to hospitalization or restricted activity, were assessed every month. Disability that lasted 6 or more consecutive months was considered long-term. RESULTS: 318 (56.0%) and 269 (53.1%) participants developed long-term disability in walking and driving, respectively. Seven risk factors were independently associated with walking disability and 8 were associated with driving disability; the strongest associations for each outcome were found for older age and lower score on the Short Physical Performance Battery. The precipitants had a large effect on long-term disability, with multivariate hazard ratios for each outcome greater than 6.2 for hospitalization and greater than 2.4 for restricted activity. The largest differences in absolute risk were generally observed in participants with a specific risk factor who were subsequently hospitalized. LIMITATIONS: The observed associations may not be causal. The severity of precipitants was not assessed. The effect of the precipitants may have been underestimated because their exposure after the initial onset of disability was not evaluated. CONCLUSION: Long-term disability in community mobility is common among older persons. Multiple risk factors, together with subsequent precipitants, greatly increase the likelihood of long-term mobility disability.

Distressing symptoms after major surgery among community-living older persons.

BACKGROUND: Relatively little is known about how distressing symptoms change among older persons in the setting of major surgery. Our objective was to evaluate changes in distressing symptoms after major surgery and determine whether these changes differ according to the timing of surgery (nonelective vs. elective), sex, multimorbidity, and socioeconomic disadvantage. METHODS: From a prospective longitudinal study of 754 nondisabled community-living persons, 70 years of age or older, 368 admissions for major surgery were identified from 274 participants who were discharged from the hospital from March 1998 to December 2017. The occurrence of 15 distressing symptoms was ascertained in the month before and 6 months after major surgery. Multimorbidity was defined as more than two chronic conditions. Socioeconomic disadvantage was assessed at the individual level, based on Medicaid eligibility, and neighborhood level, based on an area deprivation index (ADI) score above the 80th state percentile. RESULTS: In the month before major surgery, the occurrence and mean number of distressing symptoms were 19.6% and 0.75, respectively. In multivariable analyses, the rate ratios, denoting proportional increases in the 6 months after major surgery relative to presurgery values, were 2.56 (95% confidence interval [CI], 1.91-3.44) and 2.90 (95% CI, 2.01-4.18) for the occurrence and number of distressing symptoms, respectively. The corresponding values were 3.54 (95% CI, 2.06-6.08) and 4.51 for nonelective surgery (95% CI, 2.32-8.76) and 2.12 (95% CI, 1.53-2.92) and 2.20 (95% CI, 1.48-3.29) for elective surgery; p-values for interaction were 0.030 and 0.009. None of the other subgroup differences were statistically significant, although men had a greater proportional increase in the occurrence and number of distressing symptoms than women. CONCLUSIONS: Among community-living older persons, the burden of distressing symptoms increases substantially after major surgery, especially in those having nonelective procedures. Reducing symptom burden has the potential to improve quality of life and enhance functional outcomes after major surgery.

Geriatric vulnerability and the burden of disability after major surgery.

BACKGROUND: Strong epidemiologic evidence linking indicators of geriatric vulnerability to long-term functional outcomes after major surgery is lacking. The objective of this study was to evaluate the association between geriatric vulnerability and the burden of disability after hospital discharge for major surgery. METHODS: From a prospective longitudinal study of 754 nondisabled community-living persons, aged 70 years or older, 327 admissions for major surgery were identified from 247 participants who were discharged from the hospital from March 1997 to December 2017. The indicators of geriatric vulnerability were ascertained immediately prior to the major surgery or during the prior comprehensive assessment, which was completed every 18 months. Disability in 13 essential, instrumental and mobility activities was assessed each month. RESULTS: The burden of disability over the 6 months after major surgery was considerably greater for non-elective than elective surgery. In multivariable analysis, 10 factors were independently associated with disability burden: age 85 years or older, female sex, Black race or Hispanic ethnicity, neighborhood disadvantage, multimorbidity, frailty, one or more disabilities, low functional self-efficacy, smoking, and obesity. The burden of disability increased with each additional vulnerability factor, with mean values (credible intervals) increasing from 1.6 (1.4-1.9) disabilities for 0-1 vulnerability factors to 6.6 (6.0-7.2) disabilities for 7 or more vulnerability factors. The corresponding values were 1.2 (0.9-1.5) and 5.9 (5.0-6.7) disabilities for elective surgery and 2.6 (2.1-3.1) and 8.2 (7.3-9.2) disabilities for non-elective surgery. CONCLUSIONS: The burden of disability after hospital discharge for major surgery increases progressively as the number of geriatric vulnerability factors increases. These factors can be used to identify older persons who are particularly susceptible to poor functional outcomes after major surgery, and a subset may be amenable to intervention, including frailty, low functional self-efficacy, smoking, and obesity.

Trends in Restricting Symptoms at the End of Life from 1998 to 2019: A Cohort Study of Older Persons.

OBJECTIVES: To describe changes in the occurrence of restricting symptoms at the end of life from 1998 to 2019 and compare these changes according to the condition leading to death. DESIGN: Prospective longitudinal study. SETTING: Greater New Haven, CT. PARTICIPANTS: A total of 665 decedents from a cohort of 754 community-living persons, 70 years or older. MEASUREMENTS: The occurrence of 16 restricting symptoms was ascertained during monthly interviews. Information on the conditions leading to death was obtained from death certificates and comprehensive assessments that were completed every 18-months. For each restricting symptom, adjusted rates (per 100 person-months) were calculated separately for six multiyear time intervals. RESULTS: From 1998 to 2019, rates decreased for five (31.3%) restricting symptoms (difficulty sleeping; chest pain or tightness; shortness of breath; cold or flu symptoms; and nausea, vomiting, or diarrhea), increased for three (18.8%: arm or leg weakness; urinary incontinence; and memory or thinking problem), and changed little for the other eight (50.0%: poor eyesight; anxiety; depression; musculoskeletal pain; fatigue; dizziness or unsteadiness; frequent or painful urination; and swelling in feet or ankles). The decrease in rates was most pronounced for shortness of breath, with a reduction from 15.0 (95% credible interval = 11.7-18.6) in 1998 to 2001 to 8.2 (95% credible interval = 5.9-10.5) in 2014 to 2019, yielding a rate ratio (95% credible interval) of 0.92 (0.86-0.98). When evaluated according to the condition leading to death, the results were similar, with 10 of the 13 statistically significant rate ratios representing decreases in rates over time and only 3 representing increases. CONCLUSION: The occurrence of most restricting symptoms at the end of life has been decreasing or stable over the past two decades. These results suggest that end-of-life care has been improving, although additional efforts will be needed to further reduce symptom burden at the end of life.

Association Between Neighborhood Disadvantage and Functional Well-being in Community-Living Older Persons.

Importance: Neighborhood disadvantage is a novel social determinant of health that could adversely affect the functional well-being of older persons. Deficiencies in resource-poor environments can potentially be addressed through social and public health interventions. Objective: To evaluate whether estimates of active and disabled life expectancy differ on the basis of neighborhood disadvantage after accounting for individual-level socioeconomic characteristics and other prognostic factors. Design, Setting, and Participants: This prospective longitudinal cohort study included 754 nondisabled community-living persons, aged 70 years or older, who were members of the Precipitating Events Project in south central Connecticut from March 1998 to June 2020. Main Outcomes and Measures: Disability in 4 essential activities of daily living (bathing, dressing, walking, and transferring) was assessed each month. Scores on the Area Deprivation Index, a census-based socioeconomic measure with 17 education, employment, housing quality, and poverty indicators, were obtained through linkages with the 2000 Neighborhood Atlas. Area Deprivation Index scores were dichotomized at the 80th state percentile to distinguish neighborhoods that were disadvantaged (81-100) from those that were not (1-80). Results: Among the 754 participants, the mean (SD) age was 78.4 (5.3) years, and 487 (64.6%) were female. Within 5-year age increments from 70 to 90, active life expectancy was consistently lower in participants from neighborhoods that were disadvantaged vs not disadvantaged, and these differences persisted and remained statistically significant after adjustment for individual-level race and ethnicity, education, income, and other prognostic factors. At age 70 years, adjusted estimates (95% CI) for active life expectancy (in years) were 12.3 (11.5-13.1) in the disadvantaged group and 14.2 (13.5-14.7) in the nondisadvantaged group. At each age, participants from disadvantaged neighborhoods spent a greater percentage of their projected remaining life disabled, relative to those from nondisadvantaged neighborhoods, with adjusted values (SE) ranging from 17.7 (0.8) vs 15.3 (0.5) at age 70 years to 55.0 (1.7) vs 48.1 (1.3) at age 90 years. Conclusions and Relevance: In this prospective longitudinal cohort study, living in a disadvantaged neighborhood was associated with lower active life expectancy and a greater percentage of projected remaining life with disability. By addressing deficiencies in resource-poor environments, new or expanded social and public health initiatives have the potential to improve the functional well-being of community-living older persons and, in turn, reduce health disparities in the US.
