Risk Factors for 30-Day Hospital Readmission among General Surgery Patients

BACKGROUND Hospital readmission within 30 days of an index hospitalization is receiving increased scrutiny as a marker of poor-quality patient care. This study identifies factors associated with 30-day readmission after general surgery procedures. STUDY DESIGN Using standard National Surgical Quality Improvement Project protocol, preoperative, intraoperative, and postoperative outcomes were collected on patients undergoing inpatient general surgery procedures at a single academic center between 2009 and 2011. Data were merged with our institutional clinical data warehouse to identify unplanned 30-day readmissions. Demographics, comorbidities, type of procedure, postoperative complications, and ICD-9 coding data were reviewed for patients who were readmitted. Univariate and multivariate analysis was used to identify risk factors associated with 30-day readmission. RESULTS One thousand four hundred and forty-two general surgery patients were reviewed. One hundred and sixty-three (11.3%) were readmitted within 30 days of discharge. The most common reasons for readmission were gastrointestinal problem/complication (27.6%), surgical infection (22.1%), and failure to thrive/malnutrition (10.4%). Comorbidities associated with risk of readmission included disseminated cancer, dyspnea, and preoperative open wound (p < 0.05 for all variables). Surgical procedures associated with higher rates of readmission included pancreatectomy, colectomy, and liver resection. Postoperative occurrences leading to increased risk of readmission were blood transfusion, postoperative pulmonary complication, wound complication, sepsis/shock, urinary tract infection, and vascular complications. Multivariable analysis demonstrates that the most significant independent risk factor for readmission is the occurrence of any postoperative complication (odds ratio = 4.20; 95% CI, 2.89-6.13). CONCLUSIONS Risk factors for readmission after general surgery procedures are multifactorial, however, postoperative complications appear to drive readmissions in surgical patients. Taking appropriate steps to minimize postoperative complications will decrease postoperative readmissions.

Site of Extrapulmonary Tuberculosis is Associated with HIV Infection

BACKGROUND In the United States, the proportion of patients with extrapulmonary tuberculosis (EPTB) has increased relative to cases of pulmonary tuberculosis. Patients with central nervous system (CNS)/meningeal and disseminated EPTB and those with human immunodeficiency virus (HIV)/AIDS have increased mortality. The purpose of our study was to determine risk factors associated with particular types of EPTB. METHODS We retrospectively reviewed 320 cases of EPTB from 1995-2007 at a single urban US public hospital. Medical records were reviewed to determine site of EPTB and patient demographic and clinical characteristics. Multivariable logistic regression analyses were performed to determine independent associations between patient characteristics and site of disease. RESULTS Patients were predominantly male (67%), African American (82%), and US-born (76%). Mean age was 40 years (range 18-89). The most common sites of EPTB were lymphatic (28%), disseminated (23%), and CNS/meningeal (22%) disease. One hundred fifty-four (48.1%) were HIV-infected, 40% had concomitant pulmonary tuberculosis, and 14.7% died within 12 months of EPTB diagnosis. Multivariable analysis demonstrated that HIV-infected patients were less likely to have pleural (adjusted odds ratio [AOR] 0.3; 95% confidence interval [CI] .2, .6) as site of EPTB disease than HIV-uninfected patients. Among patients with EPTB and HIV-infection, patients with CD4 lymphocyte cell count <100 were more likely to have severe forms of EPTB (CNS/meningeal and/or disseminated) (AOR 1.6; 95% CI, 1.0, 2.4). CONCLUSIONS Among patients hospitalized with EPTB, patients coinfected with HIV and low CD4 counts were more likely to have CNS/meningeal and disseminated disease. Care for similar patients should include consideration of these forms of EPTB since they carry a high risk of death.

Anal cancer and intraepithelial neoplasia screening: A review

This review focuses on the early diagnosis of anal cancer and its precursor lesions through routine screening. A number of risk-stratification strategies as well as screening techniques have been suggested, and currently little consensus exists among national societies. Much of the current clinical rationale for the prevention of anal cancer derives from the similar tumor biology of cervical cancer and the successful use of routine screening to identify cervical cancer and its precursors early in the disease process. It is thought that such a strategy of identifying early anal intraepithelial neoplasia will reduce the incidence of invasive anal cancer. The low prevalence of anal cancer in the general population prevents the use of routine screening. However, routine screening of selected populations has been shown to be a more promising strategy. Potential screening modalities include digital anorectal exam, anal Papanicolaou testing, human papilloma virus co-testing, and high-resolution anoscopy. Additional research associating high-grade dysplasia treatment with anal cancer prevention as well as direct comparisons of screening regimens is necessary to develop further anal cancer screening recommendations.

Medical Student Surgery Elective in Rural Haiti: A Novel Approach to Satisfying Clerkship Requirements While Providing Surgical Care to an Underserved Population

BackgroundThe addition of global health programs to medical school training results in graduates with enhanced clinical skills and increased sensitivity to cost issues. Funding from U.S. medical schools has been unable to meet student demand, and therefore it is often a critical limiting factor to the lack of development of these programs. We describe an alternative approach for global health surgical training for medical students.MethodsEmory University medical students and faculty, in collaboration with Project Medishare for Haiti, planned, raised funds, and executed a successful short-term surgical camp to supplement available surgical services in rural Haiti. Learning objectives that satisfied Emory University School of Medicine surgery clerkship requirements were crafted, and third-year students received medical school credit for the trip.ResultsIn the absence of house staff and placed in an under-resourced, foreign clinical environment, the surgical elective described here succeeded in meeting learning objectives for a typical third-year surgical clerkship. Objectives were met through a determined effort to ensure that home institution requirements were aligned properly with learning activities while students were abroad and through a close collaboration between medical students, faculty members, and the administration.ConclusionsEmory University’s international surgery elective for medical students demonstrates that opportunities for supervised, independent student-learning and global health service can be integrated into a traditional surgical clerkship. These opportunities can be organized to meet the requirements and expectations for third-year surgery clerkships at other medical colleges. This work also identifies how such trips can be planned and executed in a manner that does not burden strained academic budgets with further demands on resources.

Is It Time to Change Guidelines for Iron Supplementation in Malarial Areas

In 2006, the recommendations of the WHO for routine iron supplementation of infants and young children were radically changed. Following publication of the results of a large clinical trial of iron and folic acid supplementation in Zanzibar (1), a WHO consultative group issued recommendations that no children under 2 years of age living in malaria-endemic areas should be provided iron supplementation without appropriate screening for iron deficiency (2). In response to this policy, iron supplementation programs have come to a halt around the world, potentially putting millions of children at risk for the adverse impacts of iron-deficiency anemia. There is now an urgent need for experts in nutrition worldwide to forthrightly discuss the safety of iron interventions and to reexamine the current WHO guidelines for iron supplementation in malaria-endemic areas. In this commentary, we raise 4 questions that policy makers should address when deciding the future of iron supplementation programs.

Intensive medical student involvement in short-term surgical trips provides safe and effective patient care: a case review

BackgroundThe hierarchical nature of medical education has been thought necessary for the safe care of patients. In this setting, medical students in particular have limited opportunities for experiential learning. We report on a student-faculty collaboration that has successfully operated an annual, short-term surgical intervention in Haiti for the last three years. Medical students were responsible for logistics and were overseen by faculty members for patient care. Substantial planning with local partners ensured that trip activities supplemented existing surgical services. A case review was performed hypothesizing that such trips could provide effective surgical care while also providing a suitable educational experience.FindingsOver three week-long trips, 64 cases were performed without any reported complications, and no immediate perioperative morbidity or mortality. A plurality of cases were complex urological procedures that required surgical skills that were locally unavailable (43%). Surgical productivity was twice that of comparable peer institutions in the region. Student roles in patient care were greatly expanded in comparison to those at U.S. academic medical centers and appropriate supervision was maintained.DiscussionThis demonstration project suggests that a properly designed surgical trip model can effectively balance the surgical needs of the community with an opportunity to expose young trainees to a clinical and cross-cultural experience rarely provided at this early stage of medical education. Few formalized programs currently exist although the experience above suggests the rewarding potential for broad-based adoption.

Patient Symptomatology in Anal Dysplasia

IMPORTANCE High-resolution anoscopy (HRA) is becoming increasingly advocated as a method of screening for anal dysplasia in high-risk patients. OBJECTIVE To describe, through HRA findings, the association between patient symptomatology and anal dysplasia among patients at high risk for anal dysplasia. DESIGN, SETTING, AND PARTICIPANTS Univariable and multivariable analyses were conducted of data from a prospectively maintained HRA database on all patients undergoing HRA with biopsy from November 1, 2011, to March 13, 2014, at a tertiary care HRA clinic. Data included demographics, medical history and comorbidities, HIV status and related measures (CD4 cell counts, HIV viral load, and use of highly active antiretroviral therapy), sexual orientation (when available), patient symptoms at initial presentation, physical examination findings, anal Papanicolaou (Pap) smear findings. MAIN OUTCOMES AND MEASURES High-resolution anoscopy diagnosis of high- vs low-grade dysplasia or no dysplasia. RESULTS One hundred sixty-one HRA biopsy specimens (mean [SEM], 1.77 [0.11] biopsy specimens per patient) were obtained from 91 patients (mean [SEM] age, 45.7 [1.2] years; 61 men [67%]; 47 black patients [52%]; and 70 human immunodeficiency virus-positive patients [77%]). Twenty-seven patients (30%) had high-grade dysplasia, 26 had low-grade dysplasia (29%), and 38 had no dysplasia (42%). The majority of patients (63 [69%]) were asymptomatic (anal pain, 11 [12%]; bleeding, 14 [15%]; and pruritus, 10 [11%]). Forty-one patients (45%) presented with anal pain (odds ratio, 5.25; 95% CI, 1.44-21.82; P = .02), and patients with either high- or low-grade dysplasia were more likely to present with anal lesions on physical examination compared with patients without dysplasia (odds ratio, 4.34; 95% CI, 1.78-11.20; P = .002). Multivariable analysis suggested that anal pain was independently associated with high-grade dysplasia (odds ratio, 6.42; 95% CI, 1.18-43.3; P = .03). CONCLUSIONS AND RELEVANCE Anal dysplasia is a silent disease that is frequently asymptomatic. However, patients with anal pain, anal lesions, and other high-risk factors are at increased risk of having high-grade anal dysplasia. These patients may benefit from routine screening with HRA.

Beyond Absolutism: Guiding Principles Needed for Humanitarian Medicine: Letter to the Editor

To the Editor: In their article in the March issue of this journal, Welling et al. [1] performed an admirable job highlighting many of the common pitfalls of humanitarian biomedical interventions and developed a series of prescriptive warnings of specific faults that should be avoided. The accompanying commentary [2] further commends the authors for their unique perspective as both physicians and members of the United States military. In their effort to caution how humanitarian medicine can cause more harm than good, however, the authors may have overstated their argument. An important unmentioned premise of humanitarian interventions is that these ventures are rarely wholly good or bad. These projects typically fall into legal and ethical gray areas that deserve qualification rather than absolute judgments of right or wrong. Welling et al. [1] frame their argument by comparing common humanitarian mistakes to the medieval concept of cardinal sins. By definition, cardinal sins were errors in action or thought that were never justifiable. This concept of moral absolutism seems an inappropriate metaphorical device for the complex relativism inherent to most humanitarian work. The disordered chaos that characterizes most humanitarian crises invites moral ambiguity, and ethical commandments that attempt to dismiss this intrinsic complexity grossly oversimplify the reality of work on the ground. For example, the authors note that politics and medical training often distract from the real ‘‘service’’ component of humanitarian biomedical interventions. To attempt to separate these various elements seems unrealistic and efforts to decouple indirect benefits of humanitarian work from direct service provision may distract from the greater purpose of undertaking such projects in the first place. Given that most humanitarian work requires institutional support (e.g., military, university, faith-based organizations), there will always be special interests beyond direct service that must be evaluated and managed appropriately. But trying to eradicate these secondary objectives is very likely impossible and could very well alienate many of the organizations that currently support such service efforts. Planning and implementing effective and appropriate biomedical humanitarian interventions is fraught with obstacles. Rather than crafting a series of ‘‘thou shalt nots’’ for medical humanitarians, what the greater community needs is a consensus-driven framework for humanitarian intervention. Lists of common mistakes are helpful, but guiding principles that encompass the clinical, educational, logistical, and ethical-legal issues surrounding medical humanitarianism are dearly needed. Such guidelines would recognize the inherent problems of these interventions and provide realistic guidance to managing the complexity and moral ambiguity of such work.

Two cases of restavek-related illness: clinical implications of foster neglect in Haiti.

Restaveks, or indentured foster children, are a poorly understood, vulnerable subclass of Haitian society. From 2001 to the present, a partnership between multiple US academic medical centers and Project Medishare for Haiti has held an ongoing series of mobile clinics in rural Haiti. Multiple cases of restavek-related illness were identified. At a recent pair of mobile clinics, the authors identified two restavek cases that were significantly worse off than their communal peer groups and required immediate care. Given the lack of a robust legal support to protect orphaned children in Haiti, clinicians have an important role in advocating for restaveks at the bedside. The plight of Haitis restaveks is widely reported in the human rights literature but is not publicly recognized as an issue for community health and wellbeing among physicians. To address these health disparities, the health consequences of an entire class of neglected children must be further explored.

Assessing clinical discharge data preferences among practicing surgeons.

BACKGROUND It is believed that many postoperative patient readmissions can be curbed via optimization of a patients discharge from hospital, but little is known about how surgeons make the decision to discharge a patient. This study explored the criteria that surgeons preferentially value in their discharge decision-making process. MATERIALS AND METHODS All surgical faculty and residents at a U.S. academic medical center were surveyed about the relative importance of specific criteria regularly used to make a discharge decision. Demographic and professional information was collected about each surgeon as well. A Kruskal-Wallis and Fishers exact test were used to describe one-way analysis of variance between groupings of surgeons. Ordered logit regressions were used to analyze variations across multiple subgroups. Factor analysis was used to further characterize statistically relevant groupings of criteria. RESULTS In total, 88 (49%) of the invited surgeons responded to the survey. Respondents reported statistically less reliance on common Laboratory tests and Patient demographics when making discharge decisions preferring Vital signs, Perioperative factors, and Functional criteria. Surgeon-specific factors that influenced discharge criteria preferences included years of clinical education and gender. Factor analysis further identified subtle variations in preferences for specific criteria groupings based on clinical education, gender, and race. CONCLUSIONS Surgeons use a wide range of clinical data when making discharge decisions. Typical measures of patient condition also appear to be used heterogeneously with a preference for binary rather than continuous measures. Further understanding the nature of these preferences may suggest novel ways of presenting discharge-relevant information to clinical decision makers to optimize discharge outcomes.
