The Evolution of the Human Hand From an Anthropologic Perspective.

Coupled with the developing brain and freed from ambulatory responsibilities, the human hand has experienced osteologic and myologic changes throughout evolutionary time that have permitted manipulative capacities of social, functional, and cultural importance in modern-day human life. Hand cupping, precision gripping, and power gripping are at the root of these evolutionary developments. It is in appreciation of the evolutionary trajectory that we can truly understand how 'form is function.' The structure of the human hand is distinct in many ways from that of even our closest relatives in the primate order (ie, chimpanzees). We present some of the key anatomic changes and evolutionary anatomic remnants of the human hand. The human hand is truly an amazing organ-the product of millions of years of selective changes.

Resilience as a Predictor of Patient Satisfaction With Nonopioid Pain Management and Patient-Reported Outcome Measures After Knee Arthroscopy.

PURPOSE: The purpose of this study was to evaluate the Brief Resilience Score (BRS) as a predictor for patient satisfaction with nonopioid pain management and patient-reported outcome measures (PROMs) after arthroscopic partial meniscectomy or chondroplasty. METHODS: One hundred seventy-five patients undergoing arthroscopic partial meniscectomy and/or chondroplasty were recruited from a single clinic and were preoperatively stratified into low-to-normal resilience or high resilience groups as measured by the BRS. Satisfaction with nonopioid pain control was assessed at a 2-week follow-up visit using the Hospital Consumer Assessment of Healthcare Provider and Systems questionnaire, and various PROMs were measured at 3 and 6 months postoperatively. Statistical analysis was performed to assess for differences in satisfaction with pain control or PROMs between resilience groups. RESULTS: Analysis revealed no statistically significant differences between the low-to-normal resilience group and the high resilience group with regard to satisfaction with nonopioid pain control or PROMs assessed at 3- or 6-month follow-ups. Outcome measures [visual analog scale pain, Knee Injury and Osteoarthritis Outcome Score (KOOS) Pain, KOOS Activities of Daily Living, KOOS Quality of Life, Single Assessment Numerical Evaluation (SANE) Knee, and Veterans Rand 12-Item Health Survey Physical and Mental Component Scores] all followed expected trajectories after surgery, without a statistically significant difference between resilience groups. CONCLUSION: This study provides evidence that preoperative resilience score, as measured by the BRS, does not correlate with postoperative patient-reported functional outcome or satisfaction with a nonopioid pain regimen after knee arthroscopy. LEVEL OF EVIDENCE: II.

Handoffs and transitions in critical care (HATRICC): protocol for a mixed methods study of operating room to intensive care unit handoffs.

BACKGROUND: Operating room to intensive care unit handoffs are high-risk events for critically ill patients. Studies in selected patient populations show that standardizing operating room to intensive care unit handoffs improves information exchange and decreases errors. To adapt these findings to mixed surgical populations, we propose to study the implementation of a standardized operating room to intensive care unit handoff process in two intensive care units currently without an existing standard process. METHODS/DESIGN: The Handoffs and Transitions in Critical Care (HATRICC) study is a hybrid effectiveness- implementation trial of operating room to intensive care unit handoffs. We will use mixed methods to conduct a needs assessment of the current handoff process, adapt published handoff processes, and implement a new standardized handoff process in two academic intensive care units. Needs assessment: We will use non-participant observation to observe the current handoff process. Focus groups, interviews, and surveys of clinicians will elicit participants' impressions about the current process. Adaptation and implementation: We will adapt published standardized handoff processes using the needs assessment findings. We will use small group simulation to test the new process' feasibility. After simulation, we will incorporate the new handoff process into the clinical work of all providers in the study units. EVALUATION: Using the same methods employed in the needs assessment phase, we will evaluate use of the new handoff process. DATA ANALYSIS: The primary effectiveness outcome is the number of information omissions per handoff episode as compared to the pre-intervention period. Additional intervention outcomes include patient intensive care unit length of stay and intensive care unit mortality. The primary implementation outcome is acceptability of the new process. Additional implementation outcomes include feasibility, fidelity and sustainability. DISCUSSION: The HATRICC study will examine the effectiveness and implementation of a standardized operating room to intensive care unit handoff process. Findings from this study have the potential to improve healthcare communication and outcomes for critically ill patients. TRIAL REGISTRATION: ClinicalTrials.gov identifier: NCT02267174.

Disparities in psychological distress and access to mental health services among immigrants with rheumatologic disease.

INTRODUCTION: Patients with rheumatologic disease experience higher rates of comorbid mental health diseases than those without. Although mental health services (MHS) can improve musculoskeletal functional outcomes, access to MHS has been limited among vulnerable populations in the United States (US). The purpose of this study was to investigate contemporary patterns of severe psychological distress and receipt of MHS among immigrant populations with rheumatologic disease in the US. METHODS: The National Health Interview Survey was queried for patients with rheumatologic disease from 2009 to 2018. Patient demographics, severe psychological distress, and receipt of MHS were collected and/or calculated. Multivariable logistic regressions assessed for factors associated with decreased receipt of MHS and severe psychological distress. RESULTS: Immigrant patients with rheumatologic disease had higher rates of severe psychological distress than US-born patients (7.7% vs. 6.5%, p < 0.001), but were less likely to access MHS (8.3% vs. 11.0%, p < 0.001). Among immigrant patients, factors associated with lower MHS receipt included being Black (AOR 0.50, 95% CI 0.32-0.77, p = 0.002), Hispanic (AOR 0.80, 95% CI 0.30-1.00, p = 0.050), Asian (AOR 0.44, 95% CI 0.31-0.63, p < 0.001), older (p < 0.001), uninsured (p < 0.001), and having self-reported poor health (p < 0.001). DISCUSSION: Immigrant patients with rheumatologic disease in the US had higher rates of severe psychological distress yet were less likely to receive MHS compared to US-born patients. Immigrants with rheumatologic illness were less likely to receive MHS if they were male, Black, Hispanic, Asian, older, lower income, or uninsured. This lack of MHS receipt may contribute to disparities in functional outcomes seen in immigrant minorities with musculoskeletal disease. Key Points • Immigrant patients with rheumatologic disease in the US had higher rates of severe psychological distress yet were less likely to receive MHS compared to US-born patients between 2009 and 2018 • Immigrants with rheumatologic illness were less likely to receive MHS if they were Black, Hispanic, Asian, older, lower income, or uninsured • Future efforts to carefully screen for mental health diseases in these vulnerable patient populations should be made while exploring patient-specific cultural considerations of MHS receipt.

Entrapment of the urinary bladder: A rare mechanism of bladder injury in pelvic trauma.

A pelvic fracture with entrapment of the urinary bladder in the fracture site is a rare pattern of injury. As the "team captains" in the trauma bay and in the care of polytraumatized patients, trauma surgeons must be aware of this entity and its implications. We report a case of acute bladder entrapment in the fracture site of a lateral compression pelvic fracture. A review of the English literature yielded four previous reports, including two patients with delayed diagnosis (Ghuman et al., 2014; Kumar et al., 1980; Wright and Taitsman, 1996; Min et al., 2010 [1-4]). Kumar and colleagues first documented bladder entrapment by a pelvic fracture in 1980 (Kumar et al., 1980 [2]). Ghuman et al. described a similar case treated with fixation of the pelvic fracture (Ghuman et al., 2014 [1]). Wright and colleagues treated a patient with bladder perforation due to entrapment diagnosed two weeks after a pelvic ring fracture (Wright and Taitsman, 1996 [3]). In this case the bladder injury was repaired, but internal fixation of the pelvis fracture was avoided due to fear of contamination. Finally, Min et al. documented a case of bladder entrapment and perforation presenting six months after non-operative management of a pelvic ring fracture. The female patient developed recurrent UTIs and dyspareunia, and imaging revealed fracture malunion with the bladder entrapped in the fracture site (Min et al., 2010 [4]). This collection of case reports demonstrates the potential for acute or delayed bladder injury even in seemingly benign pelvic fractures. A high index of suspicion is required to intervene and prevent morbidity from bladder injuries in pelvic trauma. Entrapment of the bladder may require surgical intervention even when the injury pattern would not normally dictate surgery for the pelvis or bladder alone (Bryk and Zhao, 2016 [5]). We describe the diagnosis and surgical management of bladder entrapment and present a brief review of bladder injuries associated with pelvic fractures.
