Preoperative electrocardiogram abnormalities do not predict postoperative cardiac complications in geriatric surgical patients

OBJECTIVES: Preoperative electrocardiograms (ECGs) are routinely performed on older patients before surgery. Whether patients with abnormalities on preoperative ECGs have an increased likelihood of developing postoperative cardiac complications is unknown. This study was designed to determine whether abnormalities on preoperative ECGs were predictive of postoperative cardiac complications. DESIGN: Prospective observational study. SETTING: One of the teaching hospitals of the University of California, San Francisco, Medical Center. PARTICIPANTS: Five hundred thirteen patients aged 70 and older undergoing noncardiac surgery. MEASUREMENTS: Preoperative ECGs were analyzed using the Minnesota Codes. Predefined preoperative risk factors and in-hospital postoperative cardiac complications were measured. The association between ECG abnormalities and postoperative cardiac complications was determined by multivariate logistic regression after controlling for clinical covariates. Odds ratios (ORs) and 95% confidence intervals (CIs) were reported. RESULTS: Three hundred eighty-six of 513 patients (75.2%) had at least one abnormality on their preoperative ECGs. On multivariate analysis, the predictors of postoperative cardiac complications included American Society of Anesthesiologists physical status classification of 3 or greater (OR = 2.5, 95%CI = 1.28-4.89, P = .007) and a history of congestive heart failure (OR = 2.1, 95% CI = 1.1-5.1, P = .034). The presence of abnormalities on preoperative ECGs was not associated with an increased risk of postoperative cardiac complications (OR = 0.63, 95% CI = 0.28-1.40, P = .26). CONCLUSION: Abnormalities on preoperative ECGs are common but are of limited value in predicting postoperative cardiac complications in older patients undergoing noncardiac surgery. These results suggest that obtaining preoperative ECGs based on an age cutoff alone may not be indicated, because ECG abnormalities in older people are prevalent but nonspecific and less useful than the presence and severity of comorbidities in predicting postoperative cardiac complications.     

Retrospective analysis of long-term surgical results in acromegaly: preoperative and postoperative factors predicting outcome

OBJECTIVE Sixty-one of 83 patients with acromegaly treated between 1969 and 1993 were analysed retrospectively to clarify which early postoperative factors were significant predictors of a successful long-term outcome and which preoperative factors significantly influenced the early postoperative results. PATIENTS Of the 61 patients, 30 were operated on before 1987 and 31 afterwards. A successful long-term surgical outcome was defined as a long-term mean basal GH level <6 mU/l (comparable to <3 μg/l), a normal IGF-I level, and normal GH dynamics. RESULTS Overall, 59% of patients (37% before 1987 and 81% after) had an early postoperative mean basal GH level <6 mU/l, and 56% (29% before 1987 and 77% after) met all three of the specified criteria for a successful long-term surgical outcome. Statistical analysis confirmed that GH dynamics and postoperative mean basal GH level <6 mU/l were significant predictors of the long-term surgical outcome, whereas the postoperative IGF-I level alone was not. On the other hand, abnormal preoperative GH dynamics were normalized in all patients with a postoperative mean basal level <6 mU/l. In addition, there were no patients showing an unsuccessful long-term outcome in those associated with both the early postoperative mean basal GH level <6 mU/l and normalization of the IGF-I level. Therefore, measurement of the early postoperative mean basal GH level and the IGF-I level may be an economical and simple guide to predict the long-term surgical outcome. Moreover, multivariate analysis indicated that cavernous sinus invasion was an independent significant factor influencing the early postoperative outcome. CONCLUSIONS Successful long-term surgical outcome may be predicted if early postoperative mean basal GH level is reduced to <6 mU/l (<3 μg/l) and IGF-I level becomes normal. This study also confirms that early diagnosis and treatment by an experienced endocrinologist and neurosurgeon can improve the operative results in patients with acromegaly.     

Predictors of surgical outcomes

The foundation of surgical decision-making has always been the risk-to-benefit ratio. Traditionally, the risks of complications and death, predicted by comorbid conditions, have been balanced against the benefits of disease management; that is, relief of symptoms or prevention of disease-related complications. Increasingly, patient preference and quality-of-life outcomes are entering into the decision-making process even at the price of modest increases in risk. In addition, the role of the surgeon as a predictor of outcomes has come under close scrutiny and has been demonstrated as having an effect on a number of important surgical outcomes. In the future, our methods for analyzing and reporting surgical outcomes will have to accommodate new predictors.     

Predictors of rehabilitation outcomes in frail patients treated in a geriatric hospital

OBJECTIVES: To evaluate the effect of medical indicators of health status on functional gain during rehabilitation of frail older patients. DESIGN: Observational study. SETTING: A hospital geriatric rehabilitation department (Catholic University of Rome). PARTICIPANTS: Two hundred forty-four older patients admitted consecutively for rehabilitation after acute illnesses between March 1999 and June 2000. MEASUREMENTS: Patients were evaluated with the Minimum Data Set for Post-Acute Care (MDS-PAC) assessment form soon after the admission and every 2 weeks thereafter. Two summary scales based on MDS-PAC items are designed to describe the performance in personal activities of daily living (ADLs) and the level of cognitive function (Cognitive Performance Scale). To identify predictors of functional recovery, we constructed a multiple logistic regression model having as a dependent variable the improvement of one or more points in the ADL scale. RESULTS: Patients aged 85 and older with cognitive or sensory impairment were less likely to significantly improve physical functioning after an intensive rehabilitation program. However, the cognitive impairment was the only "negative" factor that remained significant in a multivariable model (odds ratio = 0.36, 95% confidence interval = 0.14-0.92) after adjusting for several potential negative predictors. CONCLUSIONS: The results of the present study document that severe cognitive impairment may be considered a negative predictor of functional recovery after a period of intensive rehabilitation. However, the effectiveness of such a rehabilitation program in patients with dementia is controversial. Additional studies are necessary to better clarify the effect of cognitive impairment on the potential recovery of the older subjects after a period of rehabilitation and whether this is influenced by different pathologies.     

The risk factors and outcomes of preoperative hepatic dysfunction in patients who receive surgical repair for acute type A aortic dissection

BackgroundHepatic dysfunction (HD) is a common complication that can occur after surgical repair of acute type A aortic dissection (ATAAD) and is associated with poor prognosis. However, the incidence of early preoperative HD and the associated risk factors in patients with ATAAD have not been fully elucidated.MethodsA total of 984 ATAAD patients who received surgical repair within 48 hours of symptom onset at our department from January 2014 to December 2019 were retrospectively analyzed. Patients were divided into the non-HD group and the HD groups according to the Model of End-Stage Liver Disease (MELD) score before surgery. The clinical parameters and clinical outcomes of the 2 groups were collected and compared.ResultsPreoperative HD was detected in 268 patients (27.2%). The incidence of in-hospital complications, including the need for dialysis (34.0% vs. 9.2%; P<0.001), was significantly higher in patients with HD compared to patients without HD (69.8% vs. 51.0%; P<0.001). Patients with HD had a higher 30-day mortality rate compared to patients without HD (20.1% vs. 8.4%; P<0.001). Multivariate analysis demonstrated that preoperative cardiac tamponade, preoperative serum creatinine levels, and serum troponin T levels upon admission were independent predictors for preoperative HD in patients with ATAAD. Interestingly, even though preoperative HD was associated with an increased 30-day mortality rate, it did not significantly affect the long-term mortality rate (log-rank P=0.259).ConclusionsEarly HD before surgery was commonly observed in patients with ATAAD and was associated with increased in-hospital complications after surgery, but did not significantly affect long-term survival.     

Preoperative medication use and its association with postoperative length of hospital stay in surgical oncology patients receiving comprehensive geriatric assessment

Aim

The present study aimed to investigate whether preoperative medication use is associated with postoperative length of hospital stay in older adults undergoing cancer surgery.

Methods

Patients aged ≥65 years who were scheduled for cancer surgery and presented for preoperative comprehensive geriatric assessment were included in the present study. Cognitive function evaluation and preoperative medication review were carried out, as well as baseline characteristics of participants collected from electronic medical records. The primary efficacy variable was the postoperative length of stay (LOS) in hospital.

Results

A total of 475 cancer patients were included for the analysis. Baseline characteristics of participants including older age, lower body mass index (BMI) and male sex were associated with longer postoperative stay. Among the clinical variables, cancer type, number of medications, potentially inappropriate medication (PIM) and delirium‐inducing medication were found as statistically significant factors for postoperative LOS. In multivariate analysis, variables independently associated with postoperative LOS were cancer type, PIM use, BMI, and the number of medications after controlling for age, BMI, sex, cancer type, the number of medications, PIM, and delirium‐inducing medication. In subgroup analysis of gastrointestinal cancer, multiple linear regression analysis showed that PIM use and BMI were significantly associated with LOS after adjustment for age, sex, and number of medication.

Conclusions

The present study supports the impact of medication use on postoperative LOS in geriatric oncology patients. The results add a further aspect to medication optimization in older patients undergoing cancer surgery. Geriatr Gerontol Int 2018; 18: 12–19 .     

Self-reported delay in seeking care has poor validity for predicting adverse outcomes

OBJECTIVES: To determine whether self-reports of delayed care predict increased mortality and functional decline in community-dwelling elderly. DESIGN: Longitudinal cohort study. SETTING: Five counties in North Carolina. PARTICIPANTS: A total of 4,162 randomly sampled individuals aged 65 and older. MEASUREMENTS: The primary outcome was the proportional hazard ratio (HR) for death in cohorts stratified by self-reports of delayed or foregone care. A secondary outcome, functional decline, measured the cohorts' odds of developing increased dependency in activities of daily living (ADLs). Control variables included predisposing, enabling, and need factors. RESULTS: Of 3,964 eligible participants reporting, 61% never, 27% once in a while, and 12% quite often delayed care. Over 3 years, 13% of participants died, and 17% developed increased ADL dependency. Nevertheless, in unadjusted and adjusted models, neither 3-year mortality HRs nor the odds of functional decline differed between cohorts reporting varying degrees of delayed care. Survival probabilities remained higher for 15 years among those reporting delaying care often. CONCLUSION: The inability of self-reported delay to predict adverse outcomes in community-dwelling elderly suggests the need for better understanding and support of the care-seeking process and additional measures of timeliness of access.     

Teaching of geriatric health in India: Mapping the terrain

ABSTRACT

India is currently undergoing a rapid demographic transition along with a dramatic upsurge in the number of elderly adults. Creating a cadre of specialized health care professionals in geriatric medicine is clearly vital to address the health care needs of this growing population. The authors undertook a mapping of the available academic programs in geriatric health in India and examined their content, duration, architecture, and student intake. A total of 20 programs were identified in geriatric health, thus highlighting a paucity of training options in this field. Compared to Western countries, relatively few programs are offered in clinical and public health geriatrics in India. This is further compounded by an insignificant thrust of geriatrics in undergraduate health professional curricula. Our results underscore the need for a national-level curricular initiative to strengthen and mainstream the teaching of geriatric health in the country. Alternative educational strategies such as blended learning and interprofessional education should be explored to enhance geriatric health workforce competence.     

Comparing plastic surgery and otolaryngology surgical outcomes and cartilage graft preferences in pediatric rhinoplasty: A retrospective cohort study analyzing 1839 patients

Rhinoplasty in children has raised concerns about its safety in the pediatric population. There is scarcity of evidence describing outcomes and surgical techniques performed in pediatric rhinoplasty. We analyzed post-operative complications and cartilage preferences between plastic surgeons and otolaryngologists.Data was collected through the Pediatric National Surgical Improvement Program from 2012 to 2017. Current Procedure Terminology codes were used for data extraction. Patients were grouped according to type of rhinoplasty procedures (primary, secondary, and cleft rhinoplasty). A comparison between plastic surgeons and otolaryngologists was made in each group in terms of postoperative complications. Additionally, a sub-group analysis based on cartilage graft preferences was performed.During the study period, a total of 1839 patients underwent rhinoplasty procedures; plastic surgeons performed 1438 (78.2%) cases and otolaryngologists performed 401 (21.8%) cases. After analyzing each group, no significant differences were noted in terms of wound dehiscence, surgical site infection, readmission, or reoperation. Subgroup analysis revealed that plastic surgeons prefer using rib and ear cartilage, while otolaryngologists prefer septal and ear cartilage.The analysis of 1839 pediatric patients undergoing three types of rhinoplasty procedures showed similar postoperative outcomes, but different cartilage graft utilization between plastic surgeons and otolaryngologists.     

Identification of factors associated with a need for rehabilitation for patients over 65 years following admission to a general and vascular surgical service

Aim: To identify factors that predict admission to a rehabilitation hospital for patients over 65 years of age. Methods: This study reviewed the destinations of all patients over 65 years admitted to a Department of General and Vascular Surgery over 1 year to analyse factors associated with subsequent admission to a rehabilitation hospital. Data recorded included demographic characteristics, type of admission, length of stay at the primary hospital, operation, speciality type, previous admission to rehabilitation hospital, diagnoses and procedures. Results: Of the 2632 patients examined, 8.7% were subsequently admitted to a rehabilitation hospital. Multivariate analysis showed that previous admission to the rehabilitation hospital, increasing age, number of diagnoses and admission under vascular service were all independently associated with admission for rehabilitation. Conclusions: Factors associated with increased risk of requiring transfer to a rehabilitation hospital can be identified. This allows early recognition of at‐risk patients.     

Achieving goals in geriatric assessment: role of caregiver agreement and adherence to recommendations

OBJECTIVES: To determine predictors of recommendation adherence and goal attainment of family caregivers of patients at a geriatric assessment center. DESIGN: One-year prospective cohort study. SETTING: Outpatient geriatric assessment center in Connecticut. PARTICIPANTS: Two hundred consecutive new patients and their family caregivers. MEASUREMENTS: : Family caregivers were interviewed after geriatric assessment to ascertain their treatment goals for the patient. Medical records were reviewed to identify treatment recommendations. Family caregivers were interviewed 1 year later to assess adherence to recommendations and attainment of goals. RESULTS: Follow-up interviews were completed with 176 (88%) family caregivers. Common recommendations pertained to physician referral (71%), medications (46%), counseling/education (31%), diagnostic tests (30%), residential planning (26%), healthcare planning (21%), and community services (21%). Goal attainment was reported in 44% to 67% of the patient cases, depending on goal category. Caregiver agreement with recommendations predicted adherence to recommendations (adjusted relative risk (ARR)=1.99, 95% confidence interval (CI)=1.04-5.92) after adjusting for available clinical and demographic factors. In addition, adherence to recommendations predicted goal attainment in adjusted analyses (ARR=1.70, 95% CI=1.09-2.64). CONCLUSION: This study revealed a broad range of treatment recommendations in geriatric assessment and suggests that agreeing with recommendations can promote adherence and that adherence can promote goal attainment. Taken together, the results imply that articulating shared treatment recommendations may improve the quality of health care.     

Risk factors for adverse in-hospital outcomes in acute colonic diverticular hemorrhage

AIM: To investigate the factors associated with transfusion, further bleeding, and prolonged length of stay.METHODS: In total, 153 patients emergently hospitalized for diverticular bleeding who were examined by colonoscopy were prospectively enrolled. Patients in whom the bleeding source was identified received endoscopic treatment such as clipping or endoscopic ligation. After spontaneous cessation of bleeding withconservative treatment or hemostasis with endoscopic treatment, all patients were started on a liquid food diet and gradually progressed to a solid diet over 3d, and were discharged. At enrollment, we assessed smoking, alcohol, medications [non-steroidal antiinflammatory drugs(NSAIDs)], low-dose aspirin, and other antiplatelets, warfarin, acetaminophen, and oral corticosteroids), and co-morbidities [hypertension,diabetes mellitus, dyslipidemia, cerebro-cardiovascular disease, chronic liver disease, and chronic kidney disease(CKD)]. The in-hospital outcomes were need for transfusion, further bleeding after spontaneous cessation of hemorrhage, and length of hospital stay.The odds ratio(OR) for transfusion need, further bleeding, and prolonged length of stay were estimated by logistic regression analysis.RESULTS: No patients required angiographic embolization or surgery. Stigmata of bleeding occurred in 18% of patients(27/153) and was treated by endoscopic procedures. During hospitalization, 40patients(26%) received a median of 6 units of packed red blood cells. Multivariate analysis revealed that female sex(OR = 2.5, P = 0.02), warfarin use(OR= 9.3, P 0.01), and CKD(OR = 5.9, P 0.01)were independent risk factors for transfusion need.During hospitalization, 6 patients(3.9%) experienced further bleeding, and NSAID use(OR = 5.9, P = 0.04)and stigmata of bleeding(OR = 11, P 0.01) were significant risk factors. Median length of hospital stay was 8 d. Multivariate analysis revealed that age 70years(OR = 2.1, P = 0.04) and NSAID use(OR = 2.7,P = 0.03) were independent risk factors for prolonged hospitalization(≥ 8 d).CONCLUSION: In colonic diverticular bleeding, female sex, warfarin, and CKD increased the risk of transfusion requirement, while advanced age and NSAID increased the risk of prolonged hospitalization.     

The effects of a treatment protocol for cardiac surgical patients with excessive blood loss on clinical outcomes

BACKGROUND AND OBJECTIVES: Excessive blood loss (EBL) is a common complication of cardiac surgery that is associated with adverse events. The objective of this before/after study was to determine whether the implementation of a protocol for management of cardiac surgical patients with EBL was associated with improved clinical outcomes. MATERIALS AND METHODS: In November 2002, a protocol for prompt identification and aggressive management of cardiac surgical patients with EBL was implemented at our institution. The independent relationship between protocol implementation and adverse outcomes was measured by comparing the outcomes of patients who received > or = 4 RBC (red blood cell) units within 1 day of surgery and were operated on before protocol implementation (2000-02) with those operated on after protocol implementation (2003-05), using multivariable logistic regression analysis to control for the effects of confounders. The primary outcome was a composite of adverse events that included death, renal failure, stroke, and sepsis. Bootstrapping was used to confirm the validity of the results. RESULTS: Of the 11,314 patients who underwent surgery during the study period, 1875 (16.6%) received > or = 4 RBC units within 1 day of surgery, with 958 and 917 in the pre- and postprotocol periods, respectively. The composite adverse outcome occurred in 164 (17.1%) patients in the preprotocol period and 115 (12.5%) patients in the postprotocol period (P = 0.005). Protocol implementation was independently associated with reduced odds of the composite adverse outcome (odds ratio 0.67; 95% confidence interval 0.50, 0.91; P = 0.01). This estimate was stable in bootstrap sampling. CONCLUSION: Implementation of a protocol to manage EBL in cardiac surgery was independently associated with improved outcomes.     

A comparison of frailty indexes for prediction of adverse health outcomes in an elderly cohort

This study aimed to compare the predictive accuracy for several frailty-related adverse health outcomes of a cumulative index derived from the Italian population-based elderly cohort of the Conselice Study of Brain Aging (CSBA), which takes into account multiple different domains (demographic, clinical, functional, and nutritional parameters), with that of an index derived from the Study of Osteoporotic Fractures (SOF), modified for application to the CSBA database and henceforth called mSOF, which is exclusively focused on muscular fitness. Data are for 1007 CSBA participants aged ≥65 years. Investigated adverse outcomes included 4- and 7-year risk of death and 4-year risk of fractures, falls, disability, hospitalization, and nursing home placement. Accuracy for prediction of these outcomes was investigated using area under the curve (AUC) statistics. CSBA index performed better than mSOF index for prediction of mortality (p < 0.001), hospitalization (p = 0.002), and nursing home placement (p = 0.049). For all outcomes excluding falls, frailty defined by CSBA index had a slightly lower specificity but a much higher sensitivity than frailty defined by mSOF Index. In conclusion, in this elderly cohort, the multidimensional CSBA index is a better predictor of frailty-related adverse health outcomes than the unidimensional mSOF index.     

Age of transfused red blood cells and health outcomes in two surgical cohorts

Rationale

Red blood cells (RBC) undergo morphologic and biochemical changes during storage which may lead to adverse health risks upon transfusion. In prior studies, the effect of RBC age on health outcomes has been conflicting. We designed the study to assess the effects of RBC units’ storage duration on health outcomes specifically for hospitalized patients undergoing hip fracture surgery or coronary artery bypass grafting (CABG) surgery.
