Point-of-care ultrasound in geriatrics: a national survey of VA medical centers.

BACKGROUND: Point-of-care ultrasound (POCUS) can aid geriatricians in caring for complex, older patients. Currently, there is limited literature on POCUS use by geriatricians. We conducted a national survey to assess current POCUS use, training desired, and barriers among Geriatrics and Extended Care ("geriatric") clinics at Veterans Affairs Medical Centers (VAMCs). METHODS: We conducted a prospective observational study of all VAMCs between August 2019 and March 2020 using a web-based survey sent to all VAMC Chiefs of Staff and Chiefs of geriatric clinics. RESULTS: All Chiefs of Staff (n=130) completed the survey (100% response rate). Chiefs of geriatric clinics ("chiefs") at 76 VAMCs were surveyed and 52 completed the survey (68% response rate). Geriatric clinics were located throughout the United States, mostly at high-complexity, urban VAMCs. Only 15% of chiefs responded that there was some POCUS usage in their geriatric clinic, but more than 60% of chiefs would support the implementation of POCUS use. The most common POCUS applications used in geriatric clinics were the evaluation of the bladder and urinary obstruction. Barriers to POCUS use included a lack of trained providers (56%), ultrasound equipment (50%), and funding for training (35%). Additionally, chiefs reported time utilization, clinical indications, and low patient census as barriers. CONCLUSIONS: POCUS has several potential applications for clinicians caring for geriatric patients. Though only 15% of geriatric clinics at VAMCs currently use POCUS, most geriatric chiefs would support implementing POCUS use as a diagnostic tool. The greatest barriers to POCUS implementation in geriatric clinics were a lack of training and ultrasound equipment. Addressing these barriers systematically can facilitate implementation of POCUS use into practice and permit assessment of the impact of POCUS on geriatric care in the future.

Current Use and Barriers to Point-of-Care Ultrasound in Primary Care: A National Survey of VA Medical Centers.

BACKGROUND: More primary care providers (PCPs) have begun to embrace the use of point-of-care ultrasound (POCUS), but little is known about how PCPs are currently using POCUS and what barriers exist. In this prospective study, the largest systematic survey of POCUS use among PCPs, we assessed the current use, barriers to use, program management, and training needs for POCUS in primary care. METHODS: We conducted a prospective observational study of all VA Medical Centers (VAMCs) between June 2019 and March 2020 using a web-based survey sent to all VAMC Chiefs of Staff and Chiefs of primary care clinics (PCCs). RESULTS: Chiefs of PCCs at 105 VAMCs completed the survey (82% response rate). Only 13% of PCCs currently use POCUS, and the most common applications used were bladder and musculoskeletal ultrasound. Desire for POCUS training exceeded current use, but lack of trained providers (78%), ultrasound equipment (66%), and funding for training (41%) were common barriers. Program infrastructure to support POCUS use was uncommon, and only 9% of VAMCs had local policies related to POCUS. Most PCC chiefs (64%) would support POCUS training. CONCLUSIONS: Current use of POCUS in primary care is low despite the recent growth of POCUS training in Internal Medicine residency programs. Investment in POCUS training and program infrastructure is needed to expand POCUS use in primary care and ensure adequate supervision of trainees.

Current use, training, and barriers in point-of-care ultrasound in hospital medicine: A national survey of VA hospitals.

BACKGROUND: Point-of-care ultrasound (POCUS) can reduce procedural complications and improve the diagnostic accuracy of hospitalists. Currently, it is unknown how many practicing hospitalists use POCUS, which applications are used most often, and what barriers to POCUS use exist. OBJECTIVE: This study aimed to characterize current POCUS use, training needs, and barriers to use among hospital medicine groups (HMGs). DESIGN, SETTING, AND PARTICIPANTS: A prospective observational study of all Veterans Affairs (VA) medical centers was conducted between August 2019 and March 2020 using a web-based survey sent to all chiefs of HMGs. These data were compared to a similar survey conducted in 2015. RESULT: Chiefs from 117 HMGs were surveyed, with a 90% response rate. There was ongoing POCUS use in 64% of HMGs. From 2015 to 2020, procedural POCUS use decreased by 19%, but diagnostic POCUS use increased for cardiac (8%), pulmonary (7%), and abdominal (8%) applications. The most common barrier to POCUS use was lack of training (89%), and only 34% of HMGs had access to POCUS training. Access to ultrasound equipment was the least common barrier (57%). The proportion of HMGs with ≥1 ultrasound machine increased from 29% to 71% from 2015 to 2020. An average of 3.6 ultrasound devices per HMG was available, and 45% were handheld devices. CONCLUSION: From 2015 to 2020, diagnostic POCUS use increased, while procedural use decreased among hospitalists in the VA system. Lack of POCUS training is currently the most common barrier to POCUS use among hospitalists.

Development of a multisystem point of care ultrasound skills assessment checklist.

BACKGROUND: Many institutions are training clinicians in point-of-care ultrasound (POCUS), but few POCUS skills checklists have been developed and validated. We developed a consensus-based multispecialty POCUS skills checklist with anchoring references for basic cardiac, lung, abdominal, and vascular ultrasound, and peripheral intravenous line (PIV) insertion. METHODS: A POCUS expert panel of 14 physicians specializing in emergency, critical care, and internal/hospital medicine participated in a modified-Delphi approach to develop a basic POCUS skills checklist by group consensus. Three rounds of voting were conducted, and consensus was defined by ≥ 80% agreement. Items achieving < 80% consensus were discussed and considered for up to two additional rounds of voting. RESULTS: Thirteen POCUS experts (93%) completed all three rounds of voting. Cardiac, lung, abdominal, and vascular ultrasound checklists included probe location and control, basic machine setup, image quality and optimization, and identification of anatomical structures. PIV insertion included additional items for needle tip tracking. During the first round of voting, 136 (82%) items achieved consensus, and after revision and revoting, an additional 21 items achieved consensus. A total of 153 (92%) items were included in the final checklist. CONCLUSIONS: We have developed a consensus-based, multispecialty POCUS checklist to evaluate skills in image acquisition and anatomy identification for basic cardiac, lung, abdominal, and vascular ultrasound, and PIV insertion.

Enhanced carbonic anhydrase expression with calcification and fibrosis in bronchial cartilage during COPD.

Pulmonary cartilage plays a crucial structural role determining the physiologic airway compressibility and distensibility, necessary for proper mechanical function. This functionality deteriorates with aging due to increased stiffness of both airway muscle and cartilage, as well as, decreased renewal capacity. Altered airway remodeling has been suggested as a pathogenic driver of chronic obstructive pulmonary disease (COPD) through mechanisms still incompletely understood. Using paraffin-embedded lung tissue sections from archived autopsy material from COPD with non-COPD age matched controls a histopathologic analysis focused on inflammation, fibrosis and calcification was performed with special stains (Masson's trichrome and Von Kossa) and immunohistochemistry for carbonic anhydrase IV (CA IV) and Ki-67. COPD lung tissues showed increased peribronchial inflammation compared to the non-COPD. Coarse amphophilic crystalline deposits in bronchial cartilage were more frequently observed in COPD sections, which were compatible with early dystrophic calcification of the extracellular matrix and chondrocytes. Moreover, Von Kossa staining revealed a significant calcium deposition in the cartilages from COPD in comparison to the controls. Interestingly, Ki-67 immunostains demonstrated a higher overall proliferative rate, including epithelial cells, in COPD. Furthermore, Masson's trichrome staining revealed relatively increased peribronchial collagen deposition associated with a fibrotic stromal response, which may be secondary to the inflammatory milieu in COPD. To further characterize the tissue microenvironment associated with dystrophic calcification, immunohistochemistry for CA IV was used, revealing significantly increased expression in chondrocytes and peribronchial tissue in COPD. Our findings demonstrate that dystrophic calcification of the extracellular matrix and chondrocytes can be linked to CA IV expression in COPD and suggest that pH changes in pulmonary tissue associated with inflammation and calcification may play an active role in COPD.

An Autopsy Case of Pulmonary Tumor Emboli Due to Metastatic Squamous Cell Carcinoma.

A 74-year-old man with chronic obstructive pulmonary disease on home oxygen and coronary artery disease was transferred from an outside facility to obtain an inguinal lymph node biopsy to rule out malignancy. He underwent an uncomplicated procedure and was discharged the same day. While waiting for transportation, he had sudden-onset dyspnea and collapsed. After resuscitation, patient had return of spontaneous circulation and was admitted but was provided comfort care and soon expired. Autopsy showed metastatic squamous cell carcinoma with multiple bilateral tumor emboli. Pulmonary tumor embolism is a rare cause of dyspnea in cancer population. Most of the cases are diagnosed with autopsy after sudden death; however, few cases have been reported antemortem. Tumor embolism is rare and difficult to diagnose without an autopsy with a poor outcome.

Ultrasound use in the ICU for interventional pulmonology procedures.

Critical care ultrasound has shifted the paradigm of thoracic imaging by enabling the treating physician to acquire and interpret images essential for clinical decision-making, at the bedside, in real-time. Once considered impossible, lung ultrasound based on interpretation of artifacts along with true images, has gained momentum during the last decade, as an integral part of rapid evaluation algorithms for acute respiratory failure, shock and cardiac arrest. Procedural ultrasound image guidance is a standard of care for both common bedside procedures, and advanced procedures within interventional pulmonologist's (IP's) scope of practice. From IP's perspective, the lung, pleural, and chest wall ultrasound expertise is a prerequisite for mastery in pleural drainage techniques and transthoracic biopsies. Another ultrasound application of interest to the IP in the intensive care unit (ICU) setting is during percutaneous dilatational tracheostomy (PDT). As ICU demographics shift towards older and sicker patients, the indications for closed pleural drainage procedures, bedside transthoracic biopsies, and percutaneous dilatational tracheostomies have dramatically increased. Although ultrasound expertise is considered an essential IP operator skill there is no validated curriculum developed to address this component. Further, there is a need for developing an educational tool that matches up with the curriculum and could be integrated real-time with ultrasound-guided procedures.

In-Hospital Cardiac Arrest (IHCA) and Outcomes in Patients Admitted With COVID-19 Infection.

During the COVID-19 pandemic, many patients are hospitalized, and those suffering from in-hospital cardiac arrest (IHCA) have been previously reported to have poor outcomes. This is a single-center, retrospective, observational study conducted at the Veterans Affairs Medical Center, Washington, DC, USA. The inclusion criteria were: patients admitted to the hospital with a diagnosis of COVID-19 who underwent cardiopulmonary resuscitation (CPR) for IHCA. Patients were labeled as COVID-19 positive based on a laboratory-confirmed positive polymerase chain reaction test. Patients with do-not-resuscitate (DNR) orders, those who were made comfort care, or enrolled in hospice were excluded. The study was approved by the hospital's institutional review board. A total of 155 patients with COVID-19 infection were admitted; 145/155 (93.5%) admitted to the medical floor and 10/155 (6.5%) to the medical intensive care unit (MICU). 36/145 (24.8%) floor patients were upgraded to MICU. Of the 46 patients treated in MICU, 17/46 (36.9%) were excluded for DNR status. From the remaining 29/46 (63.1%) patients, 19/29 (65.5%) patients survived, and 10/29 (34.5%) patients had IHCA. All 10/10 (100%) died after CPR without return of spontaneous circulation (ROSC). The initial rhythm was non-shockable in all patients, with pulseless electrical activity (PEA) in 7/10 (70%) and asystole in 3/10 (30%) patients. Patients with COVID-19 infection who had an IHCA and underwent CPR had a 0% survival at our hospital. Discussions on advanced care options, especially CPR, with COVID-19 patients and their families, are important as the overall prognosis after CPR for IHCA is poor.

Hair-Dye-Related Accidental Poisoning and Death.

Para phenylenediamine (PPD) is a common component of hair dye as well as temporary tattoos and is a well-known cause of type 4 hypersensitivity reactions from topical exposure. While there have been several cases reported in the literature describing toxicities following ingestion, there are a paucity of reports of severe systemic disease following topical exposure. Cases of PPD ingestion have been reported to present with angioedema-like reactions, often progressing to rhabdomyolysis and renal failure. To our knowledge, there have only been two reported cases of severe reactions following topical exposure to PPD. We present a case of a 59-year-old man with topical exposure to hair dye who presented with an angioedema-like reaction shortly after topical exposure to PPD containing hair dye that rapidly progressed to rhabdomyolysis, renal failure, and eventually death.

Delayed Pneumothorax Post Transbronchial Biopsy: A Case Report.

Bronchoscopy is a common and safe procedure with low mortality rates and complications. The risk of pneumothorax (PTX) post bronchoscopy is estimated to be 0.1% but increases to 1-6% with the addition of transbronchial lung biopsy (TBB) to the procedure. Studies have shown that a short observation period is adequate after TBB, and the usual practice is to perform a portable chest radiograph (CXR) to rule out PTX. Delayed PTX is a rare complication post-TBB and very few cases have been reported in the literature. In this report, we discuss a patient with delayed PTX 48 hours post-TBB. A 71-year-old male with a history of malignancy of unknown primary with metastasis to the sacrum and vertebral column presented with lower limb weakness status post-palliative radiation to the spine. His sacral lesion biopsy was inconclusive. He was currently on oral steroids. He was noted to have a left upper lobe lung nodule on a CT scan of the chest. He underwent bronchoscopy with TBB to determine if it was a primary lung malignancy. He was stable post-procedure with an unremarkable CXR for PTX and was discharged with outpatient follow-up. Two days later, he presented to the emergency department with shortness of breath and hypoxemia. A CXR was performed, which showed a left-sided PTX. A chest tube was placed, and a follow-up CXR showed lung immediate re-expansion. The chest tube was removed after two days and the patient was discharged home after a total of four days of hospitalization. Iatrogenic PTX can be due to diagnostic and/or therapeutic interventions. PTX after procedures can be classified as acute (one to four hours post-procedure) or delayed (>4 hours post-procedure). It is recommended to have a CXR within an hour post-TBB. To our knowledge, very few cases of delayed PTX post-TBB have been reported, mostly among lung transplant patients and those with chronic infections such as tuberculosis. In prior reports, it has been speculated that a visceral pleural defect might occur during a biopsy, but is protected by blood clot formation in the proximal bronchus. A PTX then occurs after fibrinolysis of the blood clot. Low immunity and poor wound healing due to chronic inflammation or steroid use can play a role in causing a delayed PTX. Also, the use of pain drugs such as opioids is associated with iatrogenic PTX. Patients with underlying lung disease such as emphysema are more prone to developing a PTX. Another hypothesis is that a tissue flap is created after the biopsy, which obstructs the airflow during exhalation, thereby resulting in a PTX. On the other hand, it is known that lung malignancies, either primary or metastatic, can increase the risk of secondary PTX. In our case, the temporal relationship of the delayed PTX with bronchoscopy makes it more likely that it was related to the lung biopsy (in our case, poorly differentiated non-small cell carcinoma). The underlying malignancy with low immunity, chronic tissue inflammation, and current steroid use may have resulted in delayed lung healing at the biopsy site. This case report highlights the importance of considering delayed PTX among high-risk patients who undergo such procedures. Delayed PTX is a rare complication post-TBB and should be considered in patients who are stable post-procedure but present with dyspnea and/or hypoxemia even days after the procedure.

Rhabdomyolysis in Patients Hospitalized With COVID-19 Infection: Five Case Series.

The novel SARS-CoV-2 virus (severe acute respiratory syndrome coronavirus 2) is now known to cause acute respiratory distress, cytokine storm, and coagulopathy. Multiple other manifestations have been published in recent literature. Rhabdomyolysis is a syndrome of muscle damage, with release of intracellular contents into circulation. It is characterized by marked elevations of creatinine kinase levels and myoglobinuria. In this article, we describe a series of 5 cases who were admitted with COVID-19 pneumonia and had severe muscle injury, as demonstrated by significant elevation (>5 times upper limit of normal) of creatinine kinase levels likely secondary to SARS-CoV-2 virus. The median age for these patients was 65 years, and most of them suffered from diabetes and hyperlipidemia. All patients were hypertensive males. Four out of 5 patients had preserved kidney function at baseline and were chronic kidney disease (CKD) stage 2 or better. However, most of them suffered significant kidney injury and at the time of discharge one patient was CKD stage 2 or better, 2 were CKD stage 3 or worse, and 2 patients had renal failure and died due to complications of SARS-CoV-2 infection.

Pulmonary Kaposi sarcoma presenting as complete lung consolidation.

The patient in our case presented with progressive dyspnoea and cough. Chest radiograph reveals complete opacification of the hemithorax. Complete lung consolidation was not seen on chest CT. The patient in this case had extensive pulmonary and endobronchial Kaposi sarcoma (KS) that led to complete consolidation of the right lung that was diagnosed via bronchoscopy. After diagnosis, he was restarted on antiretroviral therapy and single-agent chemotherapy for treatment of pulmonary KS.

The minimum volume of pleural fluid required to diagnose malignant pleural effusion: A retrospective study.

BACKGROUND: Pleural fluid cytology is a quick and accurate method to diagnose malignant pleural effusions. The optimal volume of fluid for cytological analysis has not yet been identified, and clinical recommendation based on some published clinical experiences has been to send large volumes of fluid for cytological analysis. A quality improvement initiative at our institution was conducted to determine the volume of fluid sufficient for a diagnosis of malignant pleural effusion. MATERIALS AND METHODS: The study was approved by the Institutional Review Board. All pleural fluid specimens that were divided into three volumes (25 mL, 50 mL, and 150 mL) and sent for cytological examination were reviewed. RESULTS: A total of 74 samples from 60 individual patients were evaluable. Thirty-six patients (60%) had a previous diagnosis of malignancy. Of the 74 specimens, 26 (35.1%) were positive for malignancy. The detection rate for malignant pleural effusion by cytology for 25 mL, 50 mL, and 150 mL were 88.5%, 96.2%, and 100.0%, respectively (P = 0.16). Two specimens that were negative in the 25 mL samples turned out to be positive in the 50 mL and 150 mL samples. One specimen was negative in the 25 mL and 50 mL samples but positive in the 150 mL sample. CONCLUSIONS: Our study did not show any statistically significant difference in the detection of malignant effusion in the 25 mL, 50 mL, and 150 mL group.

A Comprehensive Multimorbidity Index for Predicting Mortality in Intensive Care Unit Patients.

BACKGROUND: Accurate prediction of mortality for patients admitted to the intensive care units (ICUs) is an important component of medical care. However, little is known about the role of multimorbidity in predicting end of life for high-risk and vulnerable patients. OBJECTIVE: The aim of the study was to derive and validate a multimorbidity risk model in an attempt to predict all-cause mortality at 6 and 12 months posthospital discharge. METHODS: This is a retrospective, observational, clinical cohort study. Data were collected on 442,692 ICU patients who received care through the Veterans Administration between January 2003 and December 2013. The primary outcome was all-cause mortality at 6 and 12 months posthospital discharge. We divided the data into derivation (80%) and validation (20%) sets. Using multivariable logistic regression models, we compared prognostic models based on age, principal diagnosis groups, physiological markers, immunosuppressants, comorbidity categories, and a newly developed multimorbidity index (MMI) based on 5695 comorbidities. The cross-validated area under the receiver operating characteristic curve (AUC) was used to report the accuracy of predicting all-cause mortality at 6 and 12 months of hospital discharge. RESULTS: The average age of patients was 68.87 years (standard deviation = 12.1), 95.9% were males, 44.9% were widowed, divorced, or separated. The relative order of accuracy in predicting mortality was the MMI (AUC = 0.84, CI = 0.83-0.84), VA Inpatient Evaluation Center index (AUC = 0.80, CI = 0.79-0.81), principal diagnosis groups (AUC = 0.74, CI = 0.73-0.74), comorbidities (AUC = 0.69, CI = 0.68-0.70), physiological markers (AUC = 0.65, CI = 0.64-0.65), age (AUC = 0.60, CI = 0.60-0.61),and immunosuppressant use (AUC = 0.59, CI = 0.58-0.59). CONCLUSIONS: The MMI improved the accuracy of predicting short- and long-term all-cause mortality for ICU patients. Further prospective studies are needed to validate the index in different clinical settings and test generalizability of results in patients outside the VA system of care.

Ultrasound-guided versus computed tomography-scan guided biopsy of pleural-based lung lesions.

BACKGROUND: Computed tomography (CT) guided biopsies have long been the standard technique to obtain tissue from the thoracic cavity and is traditionally performed by interventional radiologists. Ultrasound (US) guided biopsy of pleural-based lesions, performed by pulmonologists is gaining popularity and has the advantage of multi-planar imaging, real-time technique, and the absence of radiation exposure to patients. In this study, we aim to determine the diagnostic accuracy, the time to diagnosis after the initial consult placement, and the complications rates between the two different modalities. METHODS: A retrospective study of electronic medical records was done of patients who underwent CT-guided biopsies and US-guided biopsies for pleural-based lesions between 2005 and 2014 and the data collected were analyzed for comparing the two groups. RESULTS: A total of 158 patients underwent 162 procedures during the study period. 86 patients underwent 89 procedures in the US group, and 72 patients underwent 73 procedures in the CT group. The overall yield in the US group was 82/89 (92.1%) versus 67/73 (91.8%) in the CT group (P = 1.0). Average days to the procedure was 7.2 versus 17.5 (P = 0.00001) in the US and CT group, respectively. Complication rate was higher in CT group 17/73 (23.3%) versus 1/89 (1.1%) in the US group (P < 0.0001). CONCLUSIONS: For pleural-based lesions the diagnostic accuracy of US guided biopsy is similar to that of CT-guided biopsy, with a lower complication rate and a significantly reduced time to the procedure.

Association of 30-Day All-Cause Readmission with Long-Term Outcomes in Hospitalized Older Medicare Beneficiaries with Heart Failure.

BACKGROUND: Heart failure is the leading cause for 30-day all-cause readmission. We examined the impact of 30-day all-cause readmission on long-term outcomes and cost in a propensity score-matched study of hospitalized patients with heart failure. METHODS: Of the 7578 Medicare beneficiaries discharged with a primary diagnosis of heart failure from 106 Alabama hospitals (1998-2001) and alive at 30 days after discharge, 1519 had a 30-day all-cause readmission. Using propensity scores for 30-day all-cause readmission, we assembled a matched cohort of 1516 pairs of patients with and without a 30-day all-cause readmission, balanced on 34 baseline characteristics (mean age 75 years, 56% women, 24% African American). RESULTS: During 2-12 months of follow-up after discharge from index hospitalization, all-cause mortality occurred in 41% and 27% of matched patients with and without a 30-day all-cause readmission, respectively (hazard ratio 1.68; 95% confidence interval 1.48-1.90; P <.001). This harmful association of 30-day all-cause readmission with mortality persisted during an average follow-up of 3.1 (maximum, 8.7) years (hazard ratio 1.33; 95% confidence interval 1.22-1.45; P <.001). Patients with a 30-day all-cause readmission had higher cumulative all-cause readmission (mean, 6.9 vs 5.1; P <.001), a longer cumulative length of stay (mean, 51 vs 43 days; P <.001), and a higher cumulative cost (mean, $38,972 vs $34,025; P = .001) during 8.7 years of follow-up. CONCLUSIONS: Among Medicare beneficiaries hospitalized for heart failure, 30-day all-cause readmission was associated with a higher risk of subsequent all-cause mortality, higher number of cumulative all-cause readmission, longer cumulative length of stay, and higher cumulative cost.

Pleural fluid procalcitonin to distinguish infectious from noninfectious etiologies of pleural effusions.

In this study we investigate the diagnostic value of pleural fluid procalcitonin (PCT) in distinguishing infectious and noninfectious etiologies of pleural effusion. We reviewed the medical records of 75 hospitalized patients who underwent thoracentesis between 2011 and 2012. Data on pleural fluid lactate dehydrogenase (LDH), protein, albumin, cell count and differential, pH, Gram stain and culture, cytology, triglyceride, cholesterol, amylase, and PCT were collected. Data on serum LDH, protein, albumin, prothrombin time, normalized, and blood culture were also collected. Pleural effusions were classified into 2 groups, infectious and noninfectious. There were 18 infectious pleural effusions (IPE) and 57 noninfectious pleural effusions (NIPE). Median pleural fluid PCT was 1.088 ng/mL (0.312-2.940 ng/mL) in IPE and 0.123 ng/mL (0.05-0.263 ng/mL) in NIPE, with a P value < 0.0001. Pleural fluid PCT > 0.25 ng/mL had a sensitivity of 77.78% and specificity of 74.14% for diagnosing an IPE. A subgroup analysis of PCT in exudative infectious effusions versus exudative noninfectious malignant/paramalignant effusions showed higher levels in the former. PCT is a novel biomarker for diagnosing infectious pleural effusion, and it would be worthwhile to investigate the role of pleural PCT in assessing severity of illness, risk stratification, and antibiotic stewardship in hospitalized patients with pleural effusions.
