RESUMO

BACKGROUND: The risk of dysphagia increases with age, affecting up to 33% of adults over the age of 65. Older adults with dysphagia are at increased risk for negative physical health outcomes such as aspiration pneumonia and death. However, the relationship between dysphagia and psychosocial health is uncertain in this population. OBJECTIVE: We aimed to assess the associations between dysphagia and psychosocial health among older adults (≥ 65) with self-reported dysphagia. DESIGN: We performed a cross-sectional assessment of the National Health and Aging Trends Study (NHATS) conducted in 2019. MAIN MEASURES: Weighted logistic and linear regression models were used to assess the relationship between self-reported dysphagia and psychosocial health using established patient-reported outcome measures including those for depression, anxiety, and social isolation previously used in NHATS analyses, while adjusting for demographics, comorbid conditions, and risk factors for dysphagia identified by purposeful selection. KEY RESULTS: Among the 4041 adults in this cohort, almost half (40%) were between 70 and 74 years old, more than half were female (55%), and a significantly higher proportion were White, non-Hispanic respondents (78.1%, p < 0.01) compared with other races and ethnicities. There were 428 (10.5%) respondents reporting dysphagia symptoms within the previous month. In the multivariable model, dysphagia was associated with significantly increased odds of anxiety (OR 1.33 [1.06, 1.67]) and a significantly decreased sense of well-being (coefficient - 1.10 [- 1.66, - 0.54]), but no association was detected for social isolation. CONCLUSIONS: When accounting for factors associated with underlying physical health status, self-reported dysphagia is independently associated with negative psychosocial health and warrants attention by healthcare providers. Future studies should aim to identify causal factors and the extent to which interventions may mitigate these factors.

RESUMO

OBJECTIVE: To determine predictors of the association between being a Veteran and adult food security, as well as to examine the relation of potential covariates to this relationship. DESIGN: Data collected during 2011-2012, 2013-2014 and 2015-2016 National Health and Nutrition Examination Survey (NHANES) were pooled for analyses. Veterans (self-reported) were matched to non-Veterans on age, race/ethnicity, sex and education. Adjusted logistic regression was used to determine the odds of Veterans having high food security v. the combination of marginal, low and very low food security compared with non-Veterans. SETTING: 2011-2012, 2013-2014 and 2015-2016 NHANES. PARTICIPANTS: 1227 Veterans; 2432 non-Veterans. RESULTS: Veteran status had no effect on the proportion of food insecurities between Veterans and non-Veterans reporting high (Veterans v. non-Veteran: 79 % v. 80 %), marginal (9 % v. 8 %), low (5 % v. 6 %) and very low (8 % v. 6 %) food security (P = 0·11). However, after controlling for covariates, Veterans tended to be less likely to have high food security (OR: 0·82 (95 % CI 0·66, 1·02), P = 0·07). Further, non-Hispanic White Veterans (OR: 0·72 (95 % CI 0·55, 0·95), P = 0·02) and Veterans completing some college (OR: 0·71 (95 % CI 0·50, 0·99), P < 0·05) were significantly less likely to experience high food security compared with non-Veterans. CONCLUSION: This study supports previous research findings that after controlling for covariates, Veterans tend to be less likely to have high food security. It also highlights ethnicity and level of education as important socio-economic determinates of food security status in Veterans.

RESUMO

The Mediterranean diet (MedD) is a flexible dietary pattern which has such variability that has led to inconsistencies in definitions and assessment. The purpose of this narrative review is to evaluate scoring systems in a cultural and geographic context, from Mediterranean and non-Mediterranean countries, for comparison and application. The early MedD scoring systems (i.e. Trichopoulou's MedD Scale (T-MDS) and alternative MedD Scale (aMed)) are widely applied throughout the world but use population-specific median cut-offs which limit interpretation and cross-study comparisons. The T-MDS and aMed also do not account for non-traditional MedD foods which are consumed in greater quantities than when the scoring systems were developed. Scoring systems developed after the MedD pyramid publication in 2011 have generally used these recommendations as a basis for food group intake cut-offs, incorporating more foods/food groups as negative components, and some have included dietary and lifestyle behaviours. The different approaches to MedD assessment have created much variability in the foods/food group components included in scoring systems. Assessments that include dietary and lifestyle behaviours may reflect the nutrition transition occurring in Mediterranean countries and better guide clinical intervention approaches. While the new scoring systems are theorised to better capture MedD adherence and behaviours, comparisons are sparse in the literature and none exists outside of Europe. Consensus on food and dietary behaviours to include as well as the methodology for assigning points in MedD scoring systems is needed to advance our understanding of MedD and health relationships to promote public health messaging and clinical application.

RESUMO

BACKGROUND: Meta-analyses of previous randomised controlled trials concluded that the smooth muscle relaxant drugs tamsulosin and nifedipine assisted stone passage for people managed expectantly for ureteric colic, but emphasised the need for high-quality trials with wide inclusion criteria. We aimed to fulfil this need by testing effectiveness of these drugs in a standard clinical care setting. METHODS: For this multicentre, randomised, placebo-controlled trial, we recruited adults (aged 18-65 years) undergoing expectant management for a single ureteric stone identified by CT at 24 UK hospitals. Participants were randomly assigned by a remote randomisation system to tamsulosin 400 µg, nifedipine 30 mg, or placebo taken daily for up to 4 weeks, using an algorithm with centre, stone size (≤5 mm or >5 mm), and stone location (upper, mid, or lower ureter) as minimisation covariates. Participants, clinicians, and trial personnel were masked to treatment assignment. The primary outcome was the proportion of participants who did not need further intervention for stone clearance within 4 weeks of randomisation, analysed in a modified intention-to-treat population defined as all eligible patients for whom we had primary outcome data. This trial is registered with the European Clinical Trials Database, EudraCT number 2010-019469-26, and as an International Standard Randomised Controlled Trial, number 69423238. FINDINGS: Between Jan 11, 2011, and Dec 20, 2013, we randomly assigned 1167 participants, 1136 (97%) of whom were included in the primary analysis (17 were excluded because of ineligibility and 14 participants were lost to follow-up). 303 (80%) of 379 participants in the placebo group did not need further intervention by 4 weeks, compared with 307 (81%) of 378 in the tamsulosin group (adjusted risk difference 1·3% [95% CI -5·7 to 8·3]; p=0·73) and 304 (80%) of 379 in the nifedipine group (0·5% [-5·6 to 6·5]; p=0·88). No difference was noted between active treatment and placebo (p=0·78), or between tamsulosin and nifedipine (p=0·77). Serious adverse events were reported in three participants in the nifedipine group (one had right loin pain, diarrhoea, and vomiting; one had malaise, headache, and chest pain; and one had severe chest pain, difficulty breathing, and left arm pain) and in one participant in the placebo group (headache, dizziness, lightheadedness, and chronic abdominal pain). INTERPRETATION: Tamsulosin 400 µg and nifedipine 30 mg are not effective at decreasing the need for further treatment to achieve stone clearance in 4 weeks for patients with expectantly managed ureteric colic.

RESUMO

AIMS/HYPOTHESES: Obesity is associated with decreased insulin sensitivity (IS) and elevated plasma branched-chain amino acids (BCAAs). The purpose of this study was to investigate the relationship between BCAA metabolism and IS in overweight (OW) individuals during exercise intervention. METHODS: Whole-body leucine turnover, IS by hyperinsulinaemic-euglycaemic clamp, and circulating and skeletal muscle amino acids, branched-chain α-keto acids and acylcarnitines were measured in ten healthy controls (Control) and nine OW, untrained, insulin-resistant individuals (OW-Untrained). OW-Untrained then underwent a 6 month aerobic and resistance exercise programme and repeated testing (OW-Trained). RESULTS: IS was higher in Control vs OW-Untrained and increased significantly following exercise. IS was lower in OW-Trained vs Control expressed relative to body mass, but was not different from Control when normalised to fat-free mass (FFM). Plasma BCAAs and leucine turnover (relative to FFM) were higher in OW-Untrained vs Control, but did not change on average with exercise. Despite this, within individuals, the decrease in molar sum of circulating BCAAs was the best metabolic predictor of improvement in IS. Circulating glycine levels were higher in Control and OW-Trained vs OW-Untrained, and urinary metabolic profiling suggests that exercise induces more efficient elimination of excess acyl groups derived from BCAA and aromatic amino acid (AA) metabolism via formation of urinary glycine adducts. CONCLUSIONS/INTERPRETATION: A mechanism involving more efficient elimination of excess acyl groups derived from BCAA and aromatic AA metabolism via glycine conjugation in the liver, rather than increased BCAA disposal through oxidation and turnover, may mediate interactions between exercise, BCAA metabolism and IS. TRIAL REGISTRATION: Clinicaltrials.gov NCT01786941.

RESUMO

Mounting evidence indicates that blueberry consumption is associated with a variety of health benefits. It has been suggested that regular consumption of blueberries can support and/or protect against cardiovascular disease and function, pre-diabetes and type 2 diabetes, and brain and cognitive function in individuals with health conditions and age-related decline. Further, mechanistic investigations highlight the role of blueberry anthocyanins in mediating these health benefits, in part through interactions with gut microbiota. Also, nutritional interventions with blueberries have demonstrated the ability to improve recovery following exercise-induced muscle damage, attributable to anti-inflammatory effects. Despite these advancements in blueberry health research, research gaps persist which affects the generalizability of findings from clinical trials. To evaluate the current state of knowledge and research gaps, a blueberry health roundtable with scientific experts convened in Washington, DC (December 6-7, 2022). Discussions centered around five research domains: cardiovascular health, pre-diabetes and diabetes, brain health and cognitive function, gut health, and exercise recovery. This article synthesizes the outcomes of a blueberry research roundtable discussion among researchers in these domains, offering insights into the health benefits of blueberries and delineating research gaps and future research directions.

RESUMO

OBJECTIVE: To compare a remotely supervised weight loss and exercise intervention to lifestyle counseling for effects on cardiovascular disease risk, disease activity, and patient-reported outcomes in older patients with rheumatoid arthritis (RA) and overweight/obesity. METHODS: Twenty older (60-80 years), previously sedentary participants with seropositive RA and overweight/obesity were randomized to 16 weeks of either Supervised Weight loss and Exercise Training (SWET) or Counseling Health As Treatment (CHAT). The SWET group completed aerobic training (150 minutes/week moderate-to-vigorous intensity), resistance training (two days/week), and a hypocaloric diet (7% weight loss goal). The CHAT control group completed two lifestyle counseling sessions followed by monthly check-ins. The primary outcome was a composite metabolic syndrome z-score (MSSc) derived from fasting glucose, triglycerides, high density lipoprotein-cholesterol, minimal waist circumference, and mean arterial pressure. Secondary outcomes included RA disease activity and patient-reported outcomes. RESULTS: Both groups improved MSSc (absolute change -1.67 ± 0.64 in SWET; -1.34 ± 1.30 in CHAT; P < 0.01 for both groups) with no between-group difference. Compared with CHAT, SWET significantly improved body weight, fat mass, Disease Activity Score-28 C-reactive protein, and patient-reported physical health, physical function, mental health, and fatigue (P < 0.04 for all between-group comparisons). Based on canonical correlations for fat mass, cardiorespiratory fitness, and leg strength, component-specific effects were strongest for (1) weight loss improving MSSc, physical health, and mental health; (2) aerobic training improving physical function and fatigue; and (3) resistance training improving Disease Activity Score-28 C-reactive protein. CONCLUSION: In older patients with RA and overweight/obesity, 16 weeks of remotely supervised weight loss, aerobic training, and resistance training improve cardiometabolic health, patient-reported outcomes, and disease activity. Less intensive lifestyle counseling similarly improves cardiovascular disease risk profiles, suggesting an important role for integrative interventions in the routine clinical care of this at-risk RA population.

RESUMO

The COVID-19 pandemic limited older adults' access to preventative and diagnostic services and negatively affected accessibility to age-appropriate exercise programs. The purpose of this study was to assess the feasibility of conducting guided virtual functional fitness assessments before and after participation in an 8-week virtual, live fitness program (Vivo) designed for older adults. It was hypothesized there would be no significant difference between in-person and virtual functional fitness assessments and function would improve following the program. Thirteen community-dwelling older adults were recruited, screened, and randomly assigned to in-person-first or virtual-first fitness assessment groups. Validated assessments were delivered using standardized scripts by trained researchers and included Short Physical Performance Battery (SPPB) balance, a 30 s Chair Stand Test, 8 Foot Up-and-Go Test, 30 s Arm Curl Test, and 2 min Step Test. The eight-week, twice-a-week live virtual fitness program involved cardiovascular, balance, agility, Dual-Task, and strength training. Results showed no significant differences between all but one assessment measures, and several measures improved following the eight-week program. Fidelity checks demonstrated the high fidelity of program delivery. These findings illustrate that virtual assessments can be a feasible method to measure functional fitness in community-dwelling older adults.

RESUMO

Adequate nutrition is an essential factor in healing and immune support in pediatric patients undergoing surgery, but its importance in this setting is not consistently recognized. Standardized institutional nutrition protocols are rarely available, and some clinicians may be unaware of the importance of assessing and optimizing nutritional status. Moreover, some clinicians may be unaware of updated recommendations that call for limited perioperative fasting. Enhanced recovery protocols have been used in adult patients undergoing surgery to ensure consistent attention to nutrition and other support strategies in adult patients before and after surgery, and these are now under evaluation for use in pediatric patients as well. To support better adoption of ideal nutrition delivery, a multidisciplinary panel of experts in the fields of pediatric anesthesiology, surgery, gastroenterology, cardiology, nutrition, and research have gathered and reviewed current evidence and best practices to support nutrition goals in this setting.

RESUMO

Objective: Our aim was to evaluate relationships between swallowing difficulty (dysphagia) and social determinants of health (SDOH) in older adults ≥65 years. Method: Cross-sectional analyses were performed in community-dwelling Medicare beneficiaries from the National Health & Aging Trends Study (NHATS). The primary exposure was self-reported difficulty chewing/swallowing in the prior month. Dependent measures included a variety of SDOH outcomes (e.g., food insecurity [FI]). Weighted logistic regression models were estimated to determine associations between dysphagia and SDOH outcomes. Results: Of 4041 participants, 428 (10.6%) self-reported dysphagia. In the adjusted model, dysphagia was associated with significantly increased odds for FI (odds ratio [OR] = 1.48, 95% confidence interval [CI] = 1.06, 2.07, p = .023) and being homebound (OR = 1.32, 95% CI = 1.13, 1.55, p= < .001). Discussion: Older adults with dysphagia had increased odds of FI and being homebound. These associations have implications for health-promoting interventions at the individual and policy levels in older adults.

RESUMO

Study Objective: Shiftwork increases risk for numerous chronic diseases, which is hypothesized to be linked to disruption of circadian timing of lifestyle behaviors. However, empirical data on timing of lifestyle behaviors in real-world shift workers are lacking. To address this, we characterized the regularity of timing of lifestyle behaviors in shift-working police trainees. Methods: Using a two-group observational study design (N=18), we compared lifestyle behavior timing during 6 weeks of in-class training during dayshift, followed by 6 weeks of field-based training during either dayshift or nightshift. Lifestyle behavior timing, including sleep/wake patterns, physical activity, and meals, was captured using wearable activity trackers and mobile devices. The regularity of lifestyle behavior timing was quantified as an index score, which reflects day-to-day stability on a 24h time scale: Sleep Regularity Index (SRI), Physical Activity Regularity Index (PARI) and Mealtime Regularity Index (MRI). Logistic regression was applied to these indices to develop a composite score, termed the Behavior Regularity Index (BRI). Results: Transitioning from dayshift to nightshift significantly worsened the BRI, relative to maintaining a dayshift schedule. Specifically, nightshift led to more irregular sleep/wake timing and meal timing; physical activity timing was not impacted. In contrast, maintaining a dayshift schedule did not impact regularity indices. Conclusion: Nightshift imposed irregular timing of lifestyle behaviors, which is consistent with the hypothesis that circadian disruption contributes to chronic disease risk in shift workers. How to mitigate the negative impact of shiftwork on human health as mediated by irregular timing of sleep/wake patterns and meals deserves exploration.

RESUMO

BACKGROUND: Preoperative dysphagia screening is rare. The purpose of this study was to assess the prevalence and potential risk factors of preoperative dysphagia risk in adults preparing for surgery. METHODS: The Eating Assessment Tool (EAT-10), Patient-Generated Subjective Global Assessment Short Form (PG-SGA SF), and Sarcopenia Screening Tool (SARC-F) were self-administered in adults preparing for surgery to identify dysphagia, malnutrition, and sarcopenia risk, respectively. Other variables collected include clinical demographics, fall risk, and surgical history associated with increased dysphagia risk. Descriptive summary statistics, univariate analysis, and logistic regression were performed as appropriate. RESULTS: The median age was 69 years and preoperative dysphagia risk was 9.6%. Among 357 patients completing both EAT-10 and PG-SGA SF or SARC-F, 7.3% had preoperative dysphagia and malnutrition risk and 7.2% had preoperative dysphagia and sarcopenia risk. Preoperative dysphagia risk was 2.7 times greater in those with prior surgical history associated with increased risk of dysphagia, 2.2 times higher in women, and almost twice as high in Black patients and patients with fall risk. Logistic regression revealed significant odds ratios (ORs) for prior surgical history associated with increased risk of dysphagia (OR, 2.95; 95% CI, 1.62-5.40) and male sex (OR, 0.52; 95% CI, 0.29-0.94), and a significant relationship between preoperative dysphagia and malnutrition risk (OR, 4.56; 95% CI, 2.02-10.28) when controlling for clinical variables. CONCLUSION: The high prevalence of dysphagia risk alone and in combination with malnutrition and sarcopenia risk in community-dwelling adults underscores the need for standardized preoperative screening and optimization prior to surgery.

RESUMO

Objective: To examine the effects of a 6-month weight loss intervention on physical function, inflammatory biomarkers, and metabolic biomarkers in both those with and without osteoarthritis (OA). Design: 59 individuals ≥60 years old with obesity and a functional impairment were enrolled into this IRB approved clinical trial and randomized into one of two 6-month weight loss arms: a higher protein hypocaloric diet or a standard protein hypocaloric diet. All participants were prescribed individualized 500-kcal daily-deficit diets, with a goal of 10% weight loss. Additionally, participants participated in three, low-intensity, exercise sessions per week. Physical function, serum biomarkers and body composition data were assessed at the baseline and 6-month timepoints. Statistical analyses assessed the relationships between biomarkers, physical function, body composition, and OA status as a result of the intervention. Results: No group effects of dietary intervention were detected on any outcome measures (multiple p â€‹> â€‹0.05). During the 6-month trial, participants lost 6.2 â€‹± â€‹4.0% of their bodyweight (p â€‹< â€‹0.0001) and experienced improved physical function on the Short-Performance-Physical-Battery (p â€‹< â€‹0.0001), 8-foot-up-and-go (p â€‹< â€‹0.0001), and time to complete 10-chair-stands (p â€‹< â€‹0.0001). Adiponectin concentrations (p â€‹= â€‹0.0480) were elevated, and cartilage oligomeric matrix protein (COMP) concentrations (p â€‹< â€‹0.0001) were reduced; further analysis revealed that reductions in serum COMP concentrations were greater in OA-negative individuals. Conclusions: These results suggest that weight loss in older adults with and without OA may provide a protective effect to cartilage and OA. In particular, OA-negative individuals may be able to mitigate changes associated with OA through weight loss.

RESUMO

Patients with rheumatoid arthritis (RA) remain at an increased risk for cardiovascular disease (CVD) and mortality. RA CVD results from a combination of traditional risk factors and RA-related systemic inflammation. One hypothetical means of improving overall RA CVD risk is through reduction of excess body weight and increased physical activity. Together, weight loss and physical activity can improve traditional cardiometabolic health through fat mass loss, while also improving skeletal muscle health. Additionally, disease-related CVD risk may improve as both fat mass loss and exercise reduce systemic inflammation. To explore this hypothesis, 26 older persons with RA and overweight/obesity will be randomized to 16 weeks of a usual care control arm or to a remotely Supervised Weight Loss Plus Exercise Training (SWET) program. A caloric restriction diet (targeting 7% weight loss) will occur via a dietitian-led intervention, with weekly weigh-ins and group support sessions. Exercise training will consist of both aerobic training (150 minutes/week moderate-to-vigorous exercise) and resistance training (twice weekly). The SWET remote program will be delivered via a combination of video conference, the study YouTube channel, and study mobile applications. The primary cardiometabolic outcome is the metabolic syndrome Z score, calculated from blood pressure, waist circumference, high-density lipoprotein cholesterol, triglycerides, and glucose. RA-specific CVD risk will be assessed with measures of systemic inflammation, disease activity, patient-reported outcomes, and immune cell function. The SWET-RA trial will be the first to assess whether a remotely supervised, combined lifestyle intervention improves cardiometabolic health in an at-risk population of older individuals with RA and overweight/obesity.

RESUMO

BACKGROUND: The primary goal of this study was the fabrication, long-term stability, and measured release of a marker dye from a micro-patterned drug delivery device using (i) mechanical puncture and (ii) photodisruption with an ophthalmic Nd:YAG laser. MATERIALS AND METHODS: A drug delivery device was made from a transparent bio-compatible polymer. The device consisted of two 2.6 mm diameter reservoirs containing 10% Na fluorescein dye. The device was implanted in the rabbit's eye (n = 2) with the cap of the device facing toward the exterior of the eye. Once the animals recovered from the implant surgery, 100% anhydrous glycerol was topically applied to the eye at the implantation site to decrease light scattering in the conjunctiva and sclera. The dye was released from one of the reservoir either using a 28 G ½ needle or an ophthalmic Q-switched Nd:YAG laser. A fluorescence spectrophotometer (FS) with fiber optic probe was used to measure the half-life of the dye in the eye. Measurements of fluorescence intensity were collected until the measurements return to baseline and histology was done on the tissue surrounded the device. RESULTS: None of the devices leaked of 10% Na fluorescein dye after implant. The ablation threshold of the drug delivery device was between 6 and 10 mJ to create 100-500 µm holes. The half-life measurement of the dye was found to be 13 days at the vitreous chamber after measuring the fluorescence intensity through the dilated cornea. Histology study showed minimal immune and foreign body response such as mild inflammation. CONCLUSION: This study established that the drug delivery device seemed to elicit minimal inflammatory response and retained its fluidic content until it was released with relatively longer retention time (half-life). Thus, similar device could be used for controlled release of drugs for certain ocular diseases.

RESUMO

Determining energy requirements is vital for optimizing nutrition interventions in pro-catabolic conditions such as cancer. Gynecological cancer encompasses the most common malignancies in women, yet there is a paucity of research on its metabolic implications. The aim of this review was to explore the literature related to energy metabolism in gynecological cancers. We were particularly interested in exploring the prevalence of energy metabolism abnormalities, methodological approaches used to assess energy metabolism, and clinical implications of inaccurately estimating energy needs. A search strategy was conducted from inception to 27 July 2021. Studies investigating energy metabolism using accurate techniques in adults with any stage of gynecological cancer and the type of treatment were considered. Of the 874 articles screened for eligibility, five studies were included. The definition of energy metabolism abnormalities varied among studies. Considering this limitation, four of the five studies reported hypermetabolism. One of these studies found that hypermetabolism was more prevalent in ovarian compared to cervical cancer. Of the included studies, one reported normometabolism at the group level; individual-level values were not reported. One of the studies reported hypermetabolism pre- and post-treatment, but normometabolism when re-assessed two years post-treatment. No studies explored clinical implications of inaccurately estimating energy needs. Overall, commonly used equations may not accurately predict energy expenditure in gynecological cancers, which can profoundly impact nutritional assessment and intervention.

RESUMO

ABSTRACT: The Doctor of Nursing Practice (DNP) curriculum was initially developed in 2004. The DNP degree is a practice doctorate, which educates nurses to the highest level of clinical nursing practice. DNP students must complete a scholarly project in accordance with the American Association of Colleges of Nursing (AACN) guidelines. The project is an opportunity for the student to integrate skills into practice and demonstrate principles of advanced nursing practice. The AACN provides recommendations for the DNP project, but much confusion regarding the context and implementation of the project still exists. At one academic health sciences center, DNP project students often complete their projects within academic practice partnerships. Such partnerships are encouraged by the AACN. Several DNP quality improvement (QI) projects were submitted a hospital's interdisciplinary quality week event. Upon review, some of the abstracts were found to contain aspects of research. This finding prompted the review of all DNP project processes to standardize methods for faculty, students, the University, and the academic practice partner.

RESUMO

This study examined the relationship between dysphagia and adverse outcomes across frailty conditions among surgical patients ≥50 years of age. A retrospective cohort analysis of surgical hospitalizations in the Healthcare Cost and Utilization Project's National Inpatient Sample among patients ≥50 years of age undergoing intermediate/high risk surgery not involving the larynx, pharynx, or esophagus. Of 3,298,835 weighted surgical hospitalizations, dysphagia occurred in 1.2% of all hospitalizations and was higher in frail patients ranging from 5.4% to 11.7%. Dysphagia was associated with greater length of stay, higher total costs, increased non-routine discharges, and increased medical/surgical complications among both frail and non-frail patients. Dysphagia may be an independent risk factor for poor postoperative outcomes among surgical patients ≥50 years of age across frailty conditions and is an important consideration for providers seeking to reduce risk in vulnerable surgical populations.
