High-Throughput Image-Based Assay for Identifying In Vitro Hepatocyte Microtubule Disruption.

Disruption of microtubule stability in mammalian cells may lead to genotoxicity and carcinogenesis. The ability to screen for microtubule destabilization or stabilization is therefore a useful and efficient approach to aid in the design of molecules that are safe for human health. In this study, we developed a high-throughput 384-well assay combining immunocytochemistry with high-content imaging to assess microtubule disruption in the metabolically competent human liver cell line: HepaRG. To enhance analysis throughput, we implemented a supervised machine learning approach using a curated training library of 180 compounds. A majority voting ensemble of eight machine learning classifiers was employed for predicting microtubule disruptions. Our prediction model achieved over 99.0% accuracy and a 98.4% F1 score, which reflects the balance between precision and recall for in-sample validation and 93.5% accuracy and a 94.3% F1 score for out-of-sample validation. This automated image-based testing can provide a simple, high-throughput screening method for early stage discovery compounds to reduce the potential risk of genotoxicity for crop protection product development.

Defining Success in the Delivery of Fertility-Related Care for Patients with Differences of Sex Development.

INTRODUCTION: Individuals with differences of sex development (DSD) experience complex, often competing, medical and psychosocial challenges surrounding fertility. The study aimed to characterize how "success" in fertility-related care is conceptualized and attained among individuals with a DSD, their parents or caregivers, healthcare providers, and other stakeholders. METHODS: As part of a larger study, DSD stakeholders (n = 110) participated in semi-structured interviews covering the clinical care of patients with DSD. Primary questions included "What is a successful outcome in DSD care?" and "How do you achieve it?" with fertility as either a spontaneous or suggested topic of discussion. Transcripts were analyzed utilizing a phenomenological approach. This analysis focuses on the extracted themes related to fertility. RESULTS: Fertility was discussed by 19/24 individuals with DSD, 12/19 parents or caregivers, 35/37 healthcare providers, and 19/30 other stakeholders. Components of successful fertility-related care included (1) specific discussions surrounding the relationship between DSD and fertility potential, options for fertility preservation, and options for non-biologic parenthood; (2) early and repeated introduction of these topics; and (3) consideration of age, developmental maturity, and cultural context on decisions around fertility. Challenges included the lack of fertility outcome data in this population and the irreversibility of gonadectomy. Trade-offs identified included anatomic typicality versus function, fertility preservation versus cancer risk reduction, and balancing the different priorities of stakeholders. DISCUSSION/CONCLUSIONS: A wide range of DSD stakeholders highlighted the importance of addressing fertility concerns in achieving favorable outcomes for individuals with DSD. These stakeholder perspectives should inform fertility-related education, shared decision-making processes, and clinical care.

Patient Satisfaction Following Non-Operative Treatment of Geriatric Hip Fractures: A Case-Control Study.

Introduction: A minority of geriatric hip fracture patients pursue non-operative treatment. Compared with surgical patients, non-operative patients have higher mortality rates. However, patient satisfaction following non-operative vs operative treatment has not been investigated extensively. The purpose of this study was to compare satisfaction among non-operatively vs operatively treated hip fracture patients. Methods: We identified patients aged 60+ years with proximal femur fractures treated over a 10-year period. Excluded were patients with isolated greater/lesser trochanteric fractures. Patients or relatives were asked to complete a 6-question survey about their treatment satisfaction. Results: Survey responses from 56 operative and 28 non-operative patients were recorded. Overall, 91.1% of operative and 82.1% of non-operative patients were satisfied with their treatment course (P = 0.260). However, only 71.4% of non-operative patients were satisfied with treatment option explanations vs 83.9% of operative patients (P = 0.014). While only 64.3% of non-operative respondents were satisfied with the ultimate treatment outcome (vs 85.7% of operative patients, P = 0.025), 89.3% of patients in each cohort would choose the same treatment plan again. Discussion: Our findings highlight the complexity of defining patient satisfaction, particularly in a geriatric hip fracture population. Unlike previous studies, we chose a direct approach to quantifying patient satisfaction by asking participants specifically about satisfaction with treatment outcome and the overall treatment course. Additional survey questions were then included to assess factors considered important in treatment satisfaction, such as health care provider treatment explanations, post-treatment mobility, and palliative care service involvement. Conclusions: We identified significant differences between non-operatively and operatively treated geriatric hip fracture patients regarding satisfaction with the explanation of treatment options, and ultimate treatment outcomes. There was no significant difference in overall satisfaction with the treatment course or likelihood of choosing the same treatment again. Further research investigating patient satisfaction following geriatric hip fracture treatment is warranted.

Utilizing an acute hyperthermia-induced seizure test and pharmacokinetic studies to establish optimal dosing regimens in a mouse model of Dravet syndrome.

OBJECTIVE: The current standard of care for Dravet syndrome (DS) includes polytherapy after inadequate seizure control with one or more monotherapy approaches. Treatment guidelines are often based on expert opinions, and finding an optimal balance between seizure control and adverse drug effects can be challenging. This study utilizes the efficacy and pharmacokinetic assessment of a second-line treatment regimen that combines clobazam and sodium valproate with an add-on drug as a proof-of-principle approach to establish an effective therapeutic regimen in a DS mouse model. METHODS: We evaluated the efficacy of add-on therapies stiripentol, cannabidiol, lorcaserin, or fenfluramine added to clobazam and sodium valproate against hyperthermia-induced seizures in Scn1aA1783V/WT mice. Clobazam, N-desmethyl clobazam (an active metabolite of clobazam), sodium valproate, stiripentol, and cannabidiol concentrations were quantified in plasma and brain using liquid chromatography-tandem mass spectrometry for the combinations deemed effective against hyperthermia-induced seizures. The concentration data were used to calculate pharmacokinetic parameters via noncompartmental analysis in Phoenix WinNonLin. RESULTS: Higher doses of stiripentol or cannabidiol, in combination with clobazam and sodium valproate, were effective against hyperthermia-induced seizures in Scn1aA1783V/WT mice. In Scn1aWT/WT mice, brain clobazam and N-desmethyl clobazam concentrations were higher in the triple-drug combinations than in the clobazam monotherapy. Stiripentol and cannabidiol brain concentrations were greater in the triple-drug therapy than when given alone. SIGNIFICANCE: A polypharmacy strategy may be a practical preclinical approach to identifying efficacious compounds for DS. The drug-drug interactions between compounds used in this study may explain the potentiated efficacy of some polytherapies.

Clinical, genetic, and cognitive correlates of seizure occurrences in Phelan-McDermid syndrome.

BACKGROUND: Phelan-McDermid syndrome (PMS) is a genetic neurodevelopmental disorder caused by SHANK3 haploinsufficiency and is associated with an increased risk for seizures. Previous literature indicates that around one third of individuals with PMS also have epilepsy or seizures, with a wide range of types and ages of onset. Investigating the impact of seizures on intellectual and adaptive functioning for PMS is a primary concern for caregivers and is important to understanding the natural history of this syndrome. METHODS: We report on results from 98 individuals enrolled in a prospective, longitudinal study. We detailed seizure frequency, type, and age of onset, and we analyzed seizure occurrence with best estimate IQ, adaptive functioning, clinical features, and genotype. We conducted multiple linear regression analyses to assess the relationship between the presence of seizures and the Vineland Adaptive Behavior Scale, Second Edition (VABS-II) Adaptive Behavior Composite score and the best estimate full-scale IQ. We also performed Chi-square tests to explore associations between seizure prevalence and genetic groupings. Finally, we performed Chi-square tests and t-tests to explore the relationship between seizures and demographic features, features that manifest in infancy, and medical features. RESULTS: Seizures were present in 41% of the cohort, and age of onset was widely variable. The presence of seizures was associated with significantly lower adaptive and intellectual functioning. Genotype-phenotype analyses were discrepant, with no differences in seizure prevalence across genetic classes, but with more genes included in deletions of participants with 22q13 deletions and seizures compared to those with 22q13 deletions and no seizures. No clinical associations were found between the presence of seizures and sex, history of pre- or neonatal complications, early infancy, or medical features. In this cohort, generalized seizures were associated with developmental regression, which is a top concern for PMS caregivers. CONCLUSIONS: These results begin to eludicate correlates of seizures in individuals with PMS and highlight the importance of early seizure management. Importantly, presence of seizures was associated with adaptive and cognitive functioning. A larger cohort might be able to identify additional associations with medical features. Genetic findings suggest an increased capability to realize genotype-phenotype relationships when deletion size is taken into account.

Preferences in Clinical Care of Individuals With Differences of Sex Development.

OBJECTIVES: To identify the most important attributes related to the process of achieving, and outcomes associated with, successful care for differences of sex development (DSD). METHODS: We developed a best-worst scaling survey administered to 520 DSD stakeholders, including individuals or family members of those with DSD, health care specialists, and patient support and advocacy representatives. Fourteen process-related attributes and 16 outcome-related attributes were identified through qualitative research. We estimated relative importance scores and coefficients from regression analysis to understand the relative importance of attributes and conducted latent class analysis to explore heterogeneity in preferences. RESULTS: The 3 most important process attributes were (1) good communication between care team and patient/family, (2) care team educated patient/family about condition, and (3) care team incorporates the values of patient/family. The 3 most important outcome attributes were (1) patient satisfaction, (2) patient mental health, and (3) treatment maintains physical health. Latent class analyses showed that respondents had heterogeneous preferences. For process-related attributes, we identified 3 respondent groups: "Patient autonomy and support" (46% of respondents), "Education and care transitions" (18%), and "Shared decision-making" (36%). For outcome-related attributes, we identified 2 respondent groups: "Preserving function and appearance" (59% of respondents) and "Patient health and satisfaction" (41%). CONCLUSIONS: Outcomes such as patient satisfaction and health were the most important outcome attributes, and good communication and education from the care team were the most important process attributes. Respondents expressed heterogeneous preferences for selected DSD care attributes that providers should consider to improve satisfaction with and quality of DSD care.

Periprosthetic fractures are osteoporotic fractures: missed opportunities for osteoporosis diagnosis.

Joint replacement surgery is common in older adults, leading to increasing periprosthetic fracture (PPFx) occurrence. We reviewed all PPFx seen over a 4-year period at an academic hospital. Clinical osteoporosis could be diagnosed based on existing data in 104 (67%) at the time of PPFx. Periprosthetic fractures are generally osteoporosis-related. PURPOSE: Periprosthetic fractures (PPFx) cause morbidity, mortality, and cost. This study's purpose was to describe osteoporosis-related data available at the time of PPFx. METHODS: The electronic medical record (EMR) of PPFx patients seen over 4 years in a university orthopedic practice were reviewed. Demographic data and osteoporosis relevant parameters were collected. Prior DXA studies were reviewed, and L1 Hounsfield unit (HU) measurements were performed on CT scans obtained within 2 years before PPFx. Clinical osteoporosis was defined as prior diagnosis, prescribed osteoporosis treatment, T-score ≤ - 2.5, HU ≤ 100, or prior fracture. RESULTS: Records of 156 PPFx patients (115 F/41 M), mean (SD) age 75.4 (11.9), were reviewed. Almost all 153/156 (98%) of these fractures were femoral. Falls caused 139 (89%); 12 (8%) were spontaneous. Mean time post-arthroplasty was 7.9 (6.3) years. Prior fragility fracture(s) occurred in 72 (46%); 14 were PPFx. Osteoporosis was previously diagnosed in 45 (29%) and medications prescribed in 41 (26%). Prior to PPFx, DXA data were available in 62, mean (SD) lowest T-score was - 1.9 (0.9) and was ≤ - 2.5 in 19. CT data were available in 46; mean (SD) L1 HU was 79.0 (29.4) and was ≤ 100 in 35. Based on existing data, clinical osteoporosis could have been diagnosed in 104 (67%) at the time of PPFx. CONCLUSION: Periprosthetic fractures are osteoporosis-related. They occur in older adults, often female, and result from falls; BMD, when assessed, is low. Data available at the time of PPFx often allows osteoporosis diagnosis; this should prompt evaluation and pharmacologic treatment consideration.

Brief Report: Quantifying Speech Production Coordination from Non- and Minimally-Speaking Individuals.

PURPOSE: Non-verbal utterances are an important tool of communication for individuals who are non- or minimally-speaking. While these utterances are typically understood by caregivers, they can be challenging to interpret by their larger community. To date, there has been little work done to detect and characterize the vocalizations produced by non- or minimally-speaking individuals. This paper aims to characterize five categories of utterances across a set of 7 non- or minimally-speaking individuals. METHODS: The characterization is accomplished using a correlation structure methodology, acting as a proxy measurement for motor coordination, to localize similarities and differences to specific speech production systems. RESULTS: We specifically find that frustrated and dysregulated utterances show similar correlation structure outputs, especially when compared to self-talk, request, and delighted utterances. We additionally witness higher complexity of coordination between articulatory and respiratory subsystems and lower complexity of coordination between laryngeal and respiratory subsystems in frustration and dysregulation as compared to self-talk, request, and delight. Finally, we observe lower complexity of coordination across all three speech subsystems in the request utterances as compared to self-talk and delight. CONCLUSION: The insights from this work aid in understanding of the modifications made by non- or minimally-speaking individuals to accomplish specific goals in non-verbal communication.

Characterizing emergency department and inpatient health care utilization after seizure-related hospitalization: A retrospective cohort study.

OBJECTIVE: Seizure care is a significant driver of health care costs in both emergency department (ED) and inpatient settings, but the majority of studies have focused on inpatient admissions as the only metric of health care utilization. This study aims to better characterize ED and inpatient encounters among patients with seizure to inform care and policy. METHODS: Using statewide administrative data from the Healthcare Cost and Utilization Project State Inpatient Databases and State Emergency Department Databases from Florida and New York, we identified patients with a seizure-related index hospitalization between January 1, 2016, and December 31, 2018. Among this cohort, we examined the incidence and characteristics of subsequent acute care visits in the ED and inpatient settings for 365 days after initial hospital discharge. RESULTS: A total of 54 456 patients had an eligible seizure-related hospitalization. Patients were 49% female, predominantly White (64%) and non-Hispanic (84%), and used a public primary payer (68%). There were 36 838 (68%) patients with at least one acute care visit in the year following discharge. Overall, patients had a median of 2 (interquartile [IQR] = 1-5) subsequent acute care visits and the median time to first acute care visit was 53 days (IQR = 15-138). Of the 154 369 subsequent acute care visits, 97 399 (63%) were ED-only visits, 56 970 (37%) were readmissions, and 37 176 (24%) were seizure-related. There were 18 786 patients (35%) with four or more acute care visits over 365 days of follow-up. Patients with four or more visits contributed 84% of acute care visits and 78% of costs after initial hospitalization. SIGNIFICANCE: The majority of patients hospitalized for seizure return to the ED or hospital at least once in the year after discharge. A small portion of patients account for the majority of ED and inpatient visits as well as health care costs associated with this population, identifying a subgroup of patients who may benefit from improved inpatient and outpatient management.

Surgical Decision-Making for Individuals with Differences of Sex Development: Stakeholders' views.

Introduction: Advocacy and human rights organizations have called for a moratorium on elective surgical procedures until the patient is able to fully participate in the decision-making process. Due to the controversial nature surrounding surgery in differences of sex development (DSD) care, we aimed to assess the factors that teens and adults with DSD, parents, healthcare providers and other allied professionals consider pertinent to complex surgical decisions in DSD. Methods: Stakeholders (n=110) in DSD care participated in semi-structured interviews exploring features and potential determinants of successful healthcare outcomes. Audio-recordings were transcribed, coded, and analyzed using qualitative data software. Codes for "Process of Decision-Making" and "Successful Outcome-Surgery/Appearance/Function" were further searched using keywords "surgery," "procedure," and "timing." Results: Several themes were identified: 1) The nature or type of the decision being made; 2) Who should be involved in the decision-making process; 3) Timing of conversations about surgery; 4) Barriers to decision-making surrounding surgery; 5) The elements of surgical decision-making; and 6) The optimal approach to surgical decision-making. Many stakeholders believed children and adolescents with DSD should be involved in the process as developmentally appropriate. Conclusion: DSD include a wide range of diagnoses, some of which may require urogenital reconstruction to relieve obstruction, achieve continence, and/or address other anatomical differences whether cosmetic or functional. Adolescents and adults with DSD desired autonomy and to be part of the decision-making process. Parents were divided in their opinion of who should be involved in making elective surgical decisions: the child or parents as proxy medical decision-makers. Providers and other professionals stressed the importance of process and education around surgical decisions. Ongoing research examines how decision-makers evaluate tradeoffs associated with decision options.

Decisional Support Needed when Facing Tough Decisions: Survey of Parents with Children having Differences of Sex Development.

Introduction: Parents of infants and young children newly diagnosed with differences of sex development (DSD) commonly face medical and psychosocial management decisions at a time when they are first learning about the condition and cannot consult their child for input. The aim of this study was to identify areas of greatest need for parental decisional support. Methods: 34 parents of children receiving care for DSD at one of three US children's hospitals participated in a survey to learn what clinical and psychosocial decisions needed to be made on behalf of their child. Parents were then asked to identify and focus on a "tough" decision and respond to questions assessing factors affecting decision-making, decision-making preferences, decisional conflict, and decision regret. Descriptive analyses were conducted. Results: Decisions about surgery and aspects of sharing information about their child's condition with others were the two most frequently reported decisions overall, experienced by 97% and 88% of parents, as well as most frequently nominated as tough decisions. Many parents reported mild to moderate levels of decisional conflict (59%) and decision regret (74%). Almost all parents (94%) reported experiencing at least one factor as interfering with decision-making (e.g., "worried too much about choosing the 'wrong' option"). Parents universally reported a desire to be involved in decision-making - preferably making the final decision primarily on their own (79%), or together with their child's healthcare providers (21%). The majority of parents judged healthcare providers (82%) and patient/family organizations (58%) as trustworthy sources of information. Discussion: Parents of children with DSD encounter medical, surgical, and psychosocial management decisions. Despite difficulties including emotional distress and informational concerns (including gaps and overload), parents express strong desires to play key roles in decision-making on behalf of their children. Healthcare providers can help identify family-specific needs through observation and inquiry in the clinical context. Together with families, providers should focus on specific clinical management decisions and support parental involvement in making decisions on behalf of young children with DSD.

Co-creating a suite of patient decision aids for parents of an infant or young child with differences of sex development: A methods roadmap.

Introduction: Parents and guardians of infants and young children with differences of sex development (DSD) often face numerous health and social decisions about their child's condition. While proxy health decisions can be stressful in any circumstance, they are further exacerbated in this clinical context by significant variations in clinical presentation, parental lack of knowledge about DSD, irreversibility of some options (e.g., gonadectomy), a paucity of research available about long-term outcomes, and anticipated decisional regret. This study aimed to engage clinicians, parents, and an adult living with DSD to collaboratively develop a suite of patient decision aids (PDAs) to respond to the decisional needs of parents and guardians of infants and young children diagnosed with DSD. Methods: We used a systematic co-development process guided by the Ottawa Decision Support Framework and the International Patient Decision Aids Standards (IPDAS). The five steps were: literature selection, establish the team, decisional needs assessment, create the PDAs, and alpha testing. Results: We developed four PDAs to support parents/guardians of infants or young children diagnosed with DSD about four priority decisions identified through our decisional needs assessment: genetic testing, gender of rearing, genital surgery and gonadal surgery. All four PDAs include information for parents about DSD, the options, reasons to choose or avoid each option, and opportunities for parents/guardians to rate the importance of features of each option to clarify their values for these features. Qualitative feedback was positive from clinicians, parents and an adult living with DSD. Conclusions: These PDAs are clinical tools designed to support parents/guardians and to promote making an informed and shared DSD-related decision. While these tools are specific to DSD, they contain themes and elements translatable to other pediatric populations.

ReCANVo: A database of real-world communicative and affective nonverbal vocalizations.

Nonverbal vocalizations, such as sighs, grunts, and yells, are informative expressions within typical verbal speech. Likewise, individuals who produce 0-10 spoken words or word approximations ("minimally speaking" individuals) convey rich affective and communicative information through nonverbal vocalizations even without verbal speech. Yet, despite their rich content, little to no data exists on the vocal expressions of this population. Here, we present ReCANVo: Real-World Communicative and Affective Nonverbal Vocalizations - a novel dataset of non-speech vocalizations labeled by function from minimally speaking individuals. The ReCANVo database contains over 7000 vocalizations spanning communicative and affective functions from eight minimally speaking individuals, along with communication profiles for each participant. Vocalizations were recorded in real-world settings and labeled in real-time by a close family member who knew the communicator well and had access to contextual information while labeling. ReCANVo is a novel database of nonverbal vocalizations from minimally speaking individuals, the largest available dataset of nonverbal vocalizations, and one of the only affective speech datasets collected amidst daily life across contexts.

A Multi-Modal Approach to Islet and Pancreas Transplantation With Calcineurin-Sparing Immunosuppression Maintains Long-Term Insulin Independence in Patients With Type I Diabetes.

Long-term success in beta-cell replacement remains limited by the toxic effects of calcineurin inhibitors (CNI) on beta-cells and renal function. We report a multi-modal approach including islet and pancreas-after-islet (PAI) transplant utilizing calcineurin-sparing immunosuppression. Ten consecutive non-uremic patients with Type 1 diabetes underwent islet transplant with immunosuppression based on belatacept (BELA; n = 5) or efalizumab (EFA; n = 5). Following islet failure, patients were considered for repeat islet infusion and/or PAI transplant. 70% of patients (four EFA, three BELA) maintained insulin independence at 10 years post-islet transplant, including four patients receiving a single islet infusion and three patients undergoing PAI transplant. 60% remain insulin independent at mean follow-up of 13.3 ± 1.1 years, including one patient 9 years after discontinuing all immunosuppression for adverse events, suggesting operational tolerance. All patients who underwent repeat islet transplant experienced graft failure. Overall, patients demonstrated preserved renal function, with a mild decrease in GFR from 76.5 ± 23.1 mL/min to 50.2 ± 27.1 mL/min (p = 0.192). Patients undergoing PAI showed the greatest degree of renal impairment following initiation of CNI (56% ± 18.7% decrease in GFR). In our series, repeat islet transplant is ineffective at maintaining long-term insulin independence. PAI results in durable insulin independence but is associated with impaired renal function secondary to CNI dependence.

"It became easier once I knew": Stakeholder perspectives for educating children and teenagers about their difference of sex development.

OBJECTIVE: Secrecy about a child's difference of sex development (DSD) can lead to internalized shame and stigma. We explored how teenagers and adults with DSD, parents, healthcare providers, and allied professionals value and perceive patient education. METHODS: Stakeholders (n = 110) completed qualitative semi-structured interviews. Relevant themes for educational content were queried and organized. RESULTS: Education was consistently identified as essential to successful outcomes. There was less consistency in how to educate patients. Disagreement existed regarding who should champion the education process. Participants believed medically relevant information should be shared gradually with attention to developmental capacity. Details were lacking regarding how much or what information to share. Participants noted that vetted resources were helpful. Benefits of sharing condition-specific information with patients included supporting their psychosocial development. Barriers included parental resistance to sharing information due to shame/stigma, and cultural and/or family dynamics. CONCLUSIONS: Stakeholders' different perspectives regarding patient DSD education warrant future research to focus on the design, evaluation, and implementation of education-focused interventions. PRACTICE IMPLICATIONS: Healthcare providers are responsible for supporting the education of children and teenagers with DSD about their condition. When considering barriers, adopting a cultural or family systems framework can reduce parental resistance and promote open dialogue.

When the Brain Cares: Personal interests amplify engagement of language, self-reference, and reward regions in the brains of children with and without autism.

Human language is shaped by individual experiences and interests. However, to study language in the brain, researchers use generic stimuli, avoiding the variable personal interests that typically animate language. Thus, it is unknown how personal interests affect language function in the brain. We conducted personalized functional magnetic resonance imaging (fMRI) in 20 typically-developing children as they listened to personalized narratives about their specific interest and non-personalized, generic narratives. Personally-interesting narratives amplified engagement of language regions, producing more consistent activation patterns across individuals - even though each narrative was unique - than the generic narratives. The personalized narratives also engaged self-reference and reward areas of the brain associated with motivation. Amplification of brain responses to personally-interesting narratives was also observed in 15 autistic children, a condition characterized by both intense specific interests and difficulties with communication. Here we show that personal interests significantly affect language processing in the human brain.

Mortality Rates After Nonoperative Geriatric Hip Fracture Treatment: A Matched Cohort Analysis.

OBJECTIVE: To compare the mortality rate between geriatric patients with hip fracture treated nonoperatively and a matched cohort treated operatively. DESIGN: Retrospective Observational Matched Cohort Study. SETTING: Academic Level 1 Trauma Center. PATIENTS: Geriatric patients who sustained femoral neck and intertrochanteric/peritrochanteric fractures, excluding isolated greater trochanteric fractures. All patients older than 65 years with hip fractures over a 10-year period were identified. Operative patients were matched at a 2:1 ratio, when possible, to nonoperative patients based on Charlson Comorbidity Index and American Society of Anesthesiologists score. INTERVENTION: Nonoperative treatment or operative treatment (femoral neck fractures: cannulated screw fixation or hemiarthroplasty; intertrochanteric/peritrochanteric fractures: sliding hip screw or cephalomedullary nail fixation; or proximal femoral locking plate). MAIN OUTCOMES: Mortality calculated at 30 and 90 days, and 1-year after injury. Mortality was compared between groups using logistic regression while controlling for age, CVA/TIA, and dementia. RESULTS: Seven hundred seventy-two patients (171 nonoperative and 601 operative) were initially identified. After applying the matching algorithm, 128 nonoperative and 239 operative patients were included in the analysis. There were no significant differences in age, sex, Charlson Comorbidity Index, or American Society of Anesthesiologists score between the cohorts. Nonoperative patients had a significantly higher 1-year mortality rate than operative patients [46.1% vs. 18.0%, Odds Ratio (95% confidence interval): 3.85 (2.34-6.41), P < 0.001]. CONCLUSIONS: Geriatric patients with hip fracture treated nonoperatively had a 1-year mortality rate of 46.1%, more than double the rate among operative patients. LEVEL OF EVIDENCE: Therapeutic Level III. See Instructions for Authors for a complete description of levels of evidence.
