RESUMO

OBJECTIVES: The incidence of hospital-acquired conditions (HACs) is a serious public health issue with implications ranging from patient morbidity and mortality to negative financial impacts on patients and health care systems. Despite substantial efforts to address and reduce HACs, research into the effect of quality improvement programs is inconclusive. This study seeks to better understand the relationship between repeated reimbursement penalties and improvement in HAC quality scores. METHODS: A quantitative comparative analysis of U.S. health care data was conducted. Data on quality outcomes and hospital characteristics were sourced from the Hospital-Acquired Condition Reduction Program from fiscal years 2018 and 2019 and the Centers for Medicare & Medicaid Services Inpatient Prospective Payment System impact files, respectively. RESULTS: In total, 3123 U.S. hospitals were analyzed to compare differences between total HAC scores of hospitals with and without penalties in consecutive years. Hospitals with repeated penalties had significantly greater improvement in scores ( t497.262 = -13.00, P < 0.001), and the impact was greatest in small hospitals (<100 beds). Repeated penalties had a smaller impact on disproportionate share hospitals (Cohen d = 0.73). Among all hospitals, the effect of repeated penalties was large (Cohen d = 0.75). CONCLUSIONS: This study suggests that repeated penalties can improve quality scores in U.S. hospitals. However, the effect may be exaggerated for smaller hospitals and those that serve patient populations with a relatively higher socioeconomic status. The reason disproportionate share hospitals did not show as much improvement as nondisproportionate hospitals may be because hospitals serving vulnerable populations often have fewer resources.

RESUMO

BACKGROUND: In 2011, the American Board of Medical Specialties established clinical informatics (CI) as a subspecialty in medicine, jointly administered by the American Board of Pathology and the American Board of Preventive Medicine. Subsequently, many institutions created CI fellowship training programs to meet the growing need for informaticists. Although many programs share similar features, there is considerable variation in program funding and administrative structures. OBJECTIVES: The aim of our study was to characterize CI fellowship program features, including governance structures, funding sources, and expenses. METHODS: We created a cross-sectional online REDCap survey with 44 items requesting information on program administration, fellows, administrative support, funding sources, and expenses. We surveyed program directors of programs accredited by the Accreditation Council for Graduate Medical Education between 2014 and 2021. RESULTS: We invited 54 program directors, of which 41 (76%) completed the survey. The average administrative support received was $27,732/year. Most programs (85.4%) were accredited to have two or more fellows per year. Programs were administratively housed under six departments: Internal Medicine (17; 41.5%), Pediatrics (7; 17.1%), Pathology (6; 14.6%), Family Medicine (6; 14.6%), Emergency Medicine (4; 9.8%), and Anesthesiology (1; 2.4%). Funding sources for CI fellowship program directors included: hospital or health systems (28.3%), clinical departments (28.3%), graduate medical education office (13.2%), biomedical informatics department (9.4%), hospital information technology (9.4%), research and grants (7.5%), and other sources (3.8%) that included philanthropy and external entities. CONCLUSION: CI fellowships have been established in leading academic and community health care systems across the country. Due to their unique training requirements, these programs require significant resources for education, administration, and recruitment. There continues to be considerable heterogeneity in funding models between programs. Our survey findings reinforce the need for reformed federal funding models for informatics practice and training.

RESUMO

There is a paucity of data exploring the impact of gender, race, and insurance status on invasive management and inhospital mortality in patients with COVID-19 with ST-elevation myocardial infarction (STEMI) in the United States. The National Inpatient Sample database for the year 2020 was queried to identify all adult hospitalizations with STEMI and concurrent COVID-19. A total of 5,990 patients with COVID-19 with STEMI were identified. Women had 31% lower odds of invasive management and 32% lower odds of coronary revascularization than men. Black patients had lower odds of invasive management (odds ratio [OR] 0.61, 95% confidence interval [CI] 0.43 to 0.85, p = 0.004) than White patients. Black and Asian patients had lower odds of percutaneous coronary intervention (Black: OR 0.55, 95% CI 0.38 to 0.80, p = 0.002; Asian: OR 0.39, 95% CI 0.18 to 0.85, p = 0.018) than White patients. Uninsured patients had higher odds of getting percutaneous coronary intervention (OR 1.78, 95% CI 1.05 to 2.98, p = 0.031) and lower odds of inhospital mortality (OR 0.41, 95% CI 0.19 to 0.89, p = 0.023) than privately insured patients. Patients with out-of-hospital STEMI had 19 times higher odds of invasive management and 80% lower odds of inhospital mortality than inhospital STEMI. In conclusion, we note important gender and racial disparities in invasive management of patients with COVID-19 with STEMI. Surprisingly, uninsured patients had higher revascularization rates and lower mortality than privately insured patients.

RESUMO

Retinal artery occlusion (RAO) is an ophthalmologic emergency, leading to sudden vision loss. Understanding its risk factors and garnering information on the incidence of adverse events can provide helpful information on the cost-effective evaluation of patients and secondary prevention. In this retrospective cohort study, we used the Nationwide Readmission Database from 2016 to 2018 and queried the database to identify patients with RAO. The clinical outcomes were cumulative incidence of myocardial infarction (MI), stroke, death (in-hospital and 6 months after discharge), resource utilization, all-cause readmission at 6 months, and reasons for all-cause readmission. We identified a total of 14,527 patients with RAO. The mean age of patients with RAO was 69 ± 13 years. Hypertension (11,839, 82%), hyperlipidemia (8,868, 61%), ischemic cardiomyopathy (4,826, 33%), smoking (4,772, 33%), and diabetes (4,588, 32%) were common co-morbidities in patients with RAO. Of 14,527 patients with RAO, 308 patients (2.1%) died, 1,577 (10.9%) developed stroke, and 615 (4.2%) developed MI within 6 months. A total of 2,841 patients (24.9%) were readmitted within 6 months of discharge. Carotid artery stenosis (386, 10.8%) was the most common cause of readmission. History of stroke or transient ischemic attack and Elixhauser co-morbidity index ≥3 were predictors of stroke. Female gender, ischemic cardiomyopathy, carotid artery disease, heart failure, chronic kidney disease, and cancer were predictors of MI. Cancer, chronic kidney disease, Elixhauser co-morbidity index ≥3, Medicare/Medicaid payer status, nonelective index admission, atrial fibrillation, and carotid artery disease were predictors of 6-month all-cause readmission. In conclusion, patients with RAO have a significant burden of co-morbidities, death, stroke, MI, and readmission. RAO may be used as a clinical marker of future stroke and MI, and should trigger screening for acute vascular ischemic events.

RESUMO

BACKGROUND: Immune checkpoint inhibitors (ICIs) are standard treatments for advanced non-small cell lung cancer and have expanded use in small cell lung cancer. Although generally better tolerated than traditional chemotherapy, immune-related adverse events, such as immune checkpoint inhibitor-related pneumonitis (ICI-P), remain poorly understood toxicities that limit ICI treatment and can result in considerable morbidity. In this retrospective case-control study, we assessed a lung cancer cohort to identify ICI-P risk factors. RESEARCH QUESTION: What are the risk factors, clinical presentations, radiographic findings, and outcomes for ICI-P in a real-world lung cancer cohort? Do chronic pulmonary diseases confer increased risk for ICI-P? STUDY DESIGN AND METHODS: Medical records from lung cancer patients receiving nivolumab, pembrolizumab, or combination ipilimumab and nivolumab at six centers in North Carolina were reviewed (January 2004-July 2017). Patients with ICI-P and control participants were characterized, and logistic regression was used to assess for ICI-P risk factors. RESULTS: Three hundred fifteen lung cancer patients who predominantly received nivolumab (76.5%) or pembrolizumab (22%) were included. The incidence of ICI-P was 9.5%, with a median time to diagnosis of 52.5 days. Most patients with ICI-P had cases of high severity, and eight patients (27%) died with ongoing ICI-P treatment. Development of ICI-P was independently associated with the presence of baseline fibrosis on chest CT scan (adjusted OR [aOR], 6.61; 95% CI, 2.48-17.7), a composite measure of obstructive lung disease (aOR, 2.79; 95% CI, 1.07-7.29), and treatment with pembrolizumab (aOR, 2.57; 95% CI, 1.08-6.11). INTERPRETATION: In this cohort, ICI-P was more common and severe than previously reported and carried an unexpectedly high mortality rate. Risk for ICI-P was shown to be independently associated with several chronic pulmonary diseases, which may account for the higher incidence of ICI-P in patients with lung cancer.

RESUMO

Healthcare systems are becoming increasingly complex. Physicians are expected to be agents of change to meet the growing health needs. In the Middle East, young family doctors are subtly creating a space for advocacy. Recognising the need for compulsory advocacy training in undergraduate medical curricula, allows health workers and students a concrete exposure to social determinants of health by carrying out clinical encounters from the hospital setting to outpatient dispensaries in underprivileged areas. At the community level, they organise mobile clinics and engage in collaborative initiatives to provide primary healthcare services to vulnerable populations. To be successful, advocacy practice and training should move towards systems thinking. Family doctors need to engage and collaborate with other stakeholders within the healthcare system and understand the dynamics of the relationships between them. This empowers their role in national health agendas, especially those related to universal health coverage (UHC). Future physicians and all members of primary care teams need to partner with people outside their discipline; the idea of interdisciplinary and interprofessional collaboration should be integrated into their schooling and all forms of vocational training.

RESUMO

The study's aim was to identify disparities in the use of cardiac rehabilitation (CR) services. Data were obtained from the 2013 Behavioral Risk Factor Surveillance System (BRFSS) conducted through landline and cellular phones by the Centers for Disease Control and Prevention. Demographic, behavioral, and clinical variables were defined to explore disparities between CR users and non-users. Bivariate chi-square analyses and weighted multivariable logistic regression were used to identify disparities. Analyses were conducted using SAS version 9.4. There were 8506 individuals who had a myocardial infarction (MI) that completed the survey, and 2891 of these individuals reported using CR. The mean weighted CR utilization rate was 31.9% and varied from 17.9% (Hawaii) to 58.9% (Minnesota). Females (adjusted odds ratio (aOR) = 0.73; 0.6-0.88), African Americans (aOR = 0.63; 0.46-0.87), and those in-between the ages of 18 and 49 years-old were less likely to use CR (aOR = 0.54; 0.34-0.86) compared to their counterparts. Individuals who were high school graduates (aOR = 1.57; 1.19-2.07), attended college (aOR = 1.34; 1.01-1.79), or graduated college (aOR = 1.91; 1.41-2.61) were more likely to use CR compared to their counterparts. Non-high school graduates, females, African Americans, and those aged between 18 to 49 should be targeted to increase CR participation.

RESUMO

BACKGROUND: Non-functioning pituitary adenomas (NFAs) are the most common pituitary tumors. There is significant variability in clinical practice in terms of post-operative imaging evaluation. The objective of this manuscript is to provide an exhaustive review of published articles pertaining to the post-operative imaging evaluation of NFAs. METHODS: The MEDLINE database was queried for studies investigating imaging for the post-operative evaluation of pituitary adenomas. From an initial search of 5589 articles, 37 articles were evaluated in detail and included in this review. RESULTS: Magnetic resonance imaging (MRI) is the gold standard for post-operative monitoring of NFAs, although functional imaging modalities may improve identification of residual tumor in conjunction with MRI. The residual tumor can be distinguished from post-operative changes by experienced practitioners using high-resolution MRI in the immediate post-operative setting (within 1 week of surgery). However, continued imaging evolution in the appearance of residual tumor or resection cavity is expected up to 3 months post-operatively. CONCLUSIONS: Post-operative imaging appearance of the pituitary gland, optic apparatus, and pneumocephalus patterns, correlated with the clinical outcomes. Long-term, lifetime follow-up is warranted for NFA patients who underwent surgical resection.

RESUMO

INTRODUCTION: Renal mass biopsy is useful in the evaluation of small renal masses. We have previously reported that office based, ultrasound guided renal mass biopsy is safe, effective and feasible when performed by urologists. This study compares office based, ultrasound guided renal mass biopsy performed by urologists and hospital based renal mass biopsy. METHODS: We retrospectively studied 70 patients who underwent office based, ultrasound guided renal mass biopsy and 155 who underwent hospital based, ultrasound or computerized tomography guided renal mass biopsy for evaluation of a small renal mass (4.0 cm or less) between January 2010 and February 2016. RESULTS: A total of 70 patients underwent office based, ultrasound guided renal mass biopsy. Median age in this group was 69.5 years, median body mass index was 29.5 kg/m2 and 61.4% of the patients (43) were male. A total of 103 patients underwent hospital based, ultrasound guided biopsy. Median age in this group was 68.0 years, median body mass index was 29.3 kg/m2 and 53.4% of the patients (55) were male. Finally, 52 patients underwent hospital based, computerized tomography guided biopsy. Median age in this group was 69 years, median body mass index was 30.1 kg/m2 and 51.9% of the patients (27) were male. Median tumor size was 2.7 cm in patients undergoing office based, ultrasound guided renal mass biopsy, 2.2 cm in those undergoing hospital based, ultrasound guided biopsy and 2.1 cm in those undergoing hospital based, computerized tomography guided biopsy (p = 0.001). Renal cell carcinoma was found in 43 of 70 (61.4%), 74 of 103 (71.8%) and 33 of 52 (63.5%) respective biopsies. Respective diagnostic rates were 81.4% (57 of 70 cases), 88.3% (91 of 103) and 86.5% (45 of 52, p = 0.434). Concordance with surgical pathology was 97.7% (42 of 43 cases), 100% (35 of 35) and 100% (15 of 15), respectively. Complication rates were 4.3% (3 of 70 patients), 13.6% (14 of 103) and 13.5% (7 of 52), respectively (p = 0.096). Cost analysis revealed that when available, office based, ultrasound guided renal mass biopsy provides the health care system a total savings of approximately $46,011 yearly. CONCLUSIONS: Office based, ultrasound guided renal mass biopsy for small renal masses is a safe and efficacious option for select patients, and potentially offers greater convenience and availability as well as decreased health care costs.

RESUMO

BACKGROUND: The authors reviewed published articles pertaining to the preoperative imaging evaluation of nonfunctioning pituitary adenomas (NFPAs) and formulated recommendations. OBJECTIVE: To provide an exhaustive review of published articles pertaining to the preoperative imaging evaluation of nonfunctioning pituitary adenomas. METHODS: The MEDLINE database was queried for studies investigating imaging for the preoperative evaluation of pituitary adenomas. RESULTS: From an initial search of 5598 articles, 122 articles were evaluated in detail and included in this article. Based on analysis of these articles, the recommendations are as follows: (1) High-resolution magnetic resonance imaging (level II) is recommended as the standard for preoperative assessment of nonfunctioning pituitary adenomas, but may be supplemented with CT (level III) and fluoroscopy (level III). (2) Although there are promising results suggesting the utility of magnetic resonance spectroscopy, magnetic resonance perfusion, positron emission tomography, and single-photon emission computed tomography, there is insufficient evidence to make formal recommendations pertaining to their clinical applications. CONCLUSION: The authors identified 122 articles that form the basis of recommendations for preoperative imaging evaluation of nonfunctioning pituitary adenomas.

RESUMO

BACKGROUND: Nonfunctioning pituitary adenomas (NFPAs) are the most frequent pituitary tumors. Due to the lack of hormonal hypersecretion, posttreatment follow-up evaluation of NFPAs is challenging. OBJECTIVE: To create evidence-based guidelines in an attempt to formulate guidance for posttreatment follow-up in a consistent, rigorous, and cost-effective way. METHODS: An extensive literature search was performed. Only clinical articles describing postoperative follow-up of adult patients with NFPAs were included. To ascertain the class of evidence for the posttreatment follow-ups, the authors used the Clinical Assessment evidence-based classification. RESULTS: Twenty-three studies met the inclusion criteria with respect to answering the questions on the posttreatment radiologic, endocrinologic, and ophthalmologic follow-up. Through this search, the authors formulated evidence-based guidelines for radiologic, endocrinologic, and ophthalmologic follow-up after surgical and/or radiation treatment. CONCLUSION: Long-term radiologic, endocrinologic, and ophthalmologic surveillance monitoring after surgical and/or radiation therapy treatment of NFPAs to evaluate for tumor recurrence or regrowth, as well as pituitary and visual status, is recommended. There is insufficient evidence to make a recommendation on the duration of time of surveillance and its frequency. It is recommended that the first radiologic study to evaluate the extent of resection of the NFPA be performed ≥3 months after surgical intervention.

RESUMO

INTRODUCTION: One of the most common and effective ways of replacing missing teeth is by dental implants. Both quality and quantity of bone along with the area of implant placement govern the prognosis of the implant procedure. Certain risk factors predispose the implant treatment to high failure rate. Hence, we assessed the implant patients who were referred from private practitioners to the specialty hospitals from 2010 to 2014. MATERIALS AND METHODS: All the patients being referred from private clinics to the specialty dental hospital for the purpose of prosthetic rehabilitation by dental implants from June 2010 to July 2014 were included in the present study. Skilled oral and maxillofacial surgeons were appointed for performing the implant surgical procedures. Prosthetic rehabilitation was done after 6 to 8 weeks and after 10 to 14 weeks in implant cases without and with bone augmentation procedures respectively. Distribution of dental implants based on the indications, location, dimension of augmentation procedure, and complication of implants was analyzed and assessed for the level of significance. RESULTS: Of the patients, 712 were females, while the remaining were males. Most of the patients were in the age group of 50 to 59 years. As compared with completely edentulous patients, most of the patients required rehabilitation by a single implant. Maximum dental implants were placed in maxillary premolar region and mandibular first molar region. Over 1,000 cases in this study required rehabilitation by augmentation procedure. CONCLUSION: Partially edentulous patients are most commonly referred to specialized dental hospitals for prosthetic rehabilitation by dental implants, mostly with the purpose of implant placement. Failure rate can be minimized by following strict patient selection protocols along with following a standard surgical criterion. CLINICAL SIGNIFICANCE: Following standard surgical protocols and strict treatment planning, prognosis of the dental implant procedures can be improved to a greater extent, thereby increasing its clinical success rate.

RESUMO

Degenerative mitral stenosis (DMS) is an important cause of mitral stenosis, developing secondary to severe mitral annular calcification. With the increase in life expectancy and improved access to health care, more patients with DMS are likely to be encountered in developed nations. These patients are generally elderly with multiple comorbidities and often are high-risk candidates for surgery. The mainstay of therapy in DMS patients is medical management with heart rate control and diuretic therapy. Surgical intervention might be delayed until symptoms are severely limiting and cannot be managed by medical therapy. Mitral valve surgery is also challenging in these patients because of the presence of extensive calcification. Hence, there is a need to develop an alternative percutaneous treatment approach for patients with DMS who are otherwise inoperable or at high risk for surgery. In this review, we summarize the available data on the epidemiology of DMS and diagnostic considerations and current treatment strategies for these patients.

RESUMO

PURPOSE: To review the utility of intraoperative imaging in facilitating maximal resection of non-functioning pituitary adenomas (NFAs). METHODS: We performed an exhaustive MEDLINE search, which yielded 5598 articles. Upon careful review of these studies, 31 were pertinent to the issue of interest. RESULTS: Nine studies examined whether intraoperative MRI (iMRI) findings correlated with the presence of residual tumor on MRI taken 3 months after surgical resection. All studies using iMRI of >0.15T showed a ≥90% concordance between iMRI and 3-month post-operative MRI findings. 24 studies (22 iMRI and 2 intraoperative CT) examined whether intraoperative imaging improved the surgeon's ability to achieve a more complete resection. The resections were carried out under microscopic magnification in 17 studies and under endoscopic visualization in 7 studies. All studies support the value of intraoperative imaging in this regard, with improved resection in 15-83% of patients. Two studies examined whether iMRI (≥0.3T) improved visualization of residual NFA when compared to endoscopic visualization. Both studies demonstrated the value of iMRI in this regard, particularly when the tumor is located lateral of the sella, in the cavernous sinus, and in the suprasellar space. CONCLUSION: The currently available literature supports the utility of intraoperative imaging in facilitating increased NFA resection, without compromising safety.

RESUMO

OBJECT: The purpose of this study is to evaluate the efficacy of betadine irrigation in preventing postoperative wound infection in cranial neurosurgical procedures. METHODS: A total of 473 consecutive cranial neurosurgical procedures, including craniotomies and burr hole procedures were retrospectively reviewed. Patients had either antibiotic irrigation or dilute betadine plus antibiotic irrigation prior to skin closure. Infection was determined by purulence noted on reoperation and confirmed with bacterial growth culture. One and three month postoperative infection rates were calculated. Statistical analysis was performed using Chi-squared tests. RESULTS: This study included 404 patients. Betadine was used in 117 (29.0%). At 1 month after surgery, there was no difference in the rate of wound infection between the two groups (1.7% each). However, at 90 days, the betadine group had a 2.6% infection rate compared with 3.8% in the antibiotic group, indicating a 33% decrease in infection rates with the addition of betadine (p=.527). The small sample size of the study produced a low power and high beta error. CONCLUSIONS: In this small preliminary study, betadine decreased postoperative infection rates compared with antibiotic prophylaxis alone at 90 days but not 30 days. This was not statistically significant, but a larger sample size would lower the beta error and decrease confounding bias associated with group heterogeneity. The potential for betadine, a cheap, low toxicity antimicrobial, to decrease infection rates and reoperations for infection warrants a larger multicenter trial.

BACKGROUND: In low- and middle-income countries burn injuries remain responsible for a large burden of death and disability. Given an annual worldwide incidence of almost 11 million new individuals affected per year, major burn injuries have a higher annual incidence than HIV and tuberculosis combined. METHODS: A survey instrument was adapted for use as an international assessment tool and then used to measure the availability of personnel, materials, equipment, medicines, and facility resources in nine Rwandan hospitals, including three referral centers. RESULTS: Forty-four percent of surveyed hospitals had a dedicated acute-care burn ward, while two-thirds had intensive care options. Relevant wound-care supplies were widely available, but gaps in the availability of critical pieces of equipment such as monitors, ventilators, infusion pumps, electrocautery, and dermatomes were discovered in many of the surveyed institutions, including referral hospitals. Early excision and grafting were not performed in any of the hospitals and there were no physicians with specialty training in burn care. CONCLUSIONS: Whereas all surveyed hospitals were theoretically equipped to handle the initial resuscitation of burn patients, none of the hospitals were capable of delivering comprehensive care due to gaps in equipment, personnel, protocols, and training. Accordingly, steps to improve capacity to care for those with thermal injury should include training of physicians specialized in critical care and trauma surgery, as well as plastic and reconstructive surgery. Consideration should be given to creation of national referral centers specializing in burn care.
