Five Questions to Help Prompt End-of-Life Planning in Neuromuscular Disease.

Patients with neuromuscular disease are living longer lives but continue to have significant and often unpredictable morbidity and mortality. End-of-life planning for these patients is thus an essential part of their medical care. This planning should include the following topics: health care surrogates, swallowing and nutrition, daytime respiratory support, and all aspects of when end of life is near. Adult-onset and early-onset diseases may require different approaches to these topics. All patients with neuromuscular disease will benefit from these discussions to best reach patient-centered goals. We present health care providers these five questions and explanations as a guide.

The Effect of In-Person Primary and Secondary School Instruction on County-Level Severe Acute Respiratory Syndrome Coronavirus 2 Spread in Indiana.

BACKGROUND: Our goal was to determine the county-level effect of in-person primary and secondary school reopening on daily cases of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) in Indiana. METHODS: In this county-level, population-based study, we used a panel data regression analysis of the proportion of in-person learning to evaluate an association with community-wide daily new SARS-CoV-2 cases. The study period was 12 July 2020-6 October 2020. We included 73 of 92 (79.3%) Indiana counties in the analysis, accounting for 85.7% of school corporations and 90.6% of student enrollment statewide. The primary exposure was the proportion of students returning to in-person instruction. The primary outcome was the daily new SARS-CoV-2 cases per 100 000 residents at the county level. RESULTS: There is a statistically significant relationship between the proportion of students attending K-12 schools in-person and the county level daily cases of SARS-CoV-2 28 days later. For all ages, the coefficient of interest (ß) is estimated at 3.36 (95% confidence interval, 1.91 to 4.81; P < .001). This coefficient represents the effect of a change in the proportion of students attending in-person on new daily cases 28 days later. For example, a 10 percentage point increase in K-12 students attending school in-person is associated with a daily increase in SARS-CoV-2 cases in the county equal to 0.336 cases/100 000 residents of all ages. CONCLUSIONS: In-person primary and secondary school is associated with a statistically significant but proportionally small increase in the spread of SARS-CoV-2 cases.

Twelve tips for teaching in the ICU.

The intensive care unit (ICU) provides unique educational opportunities for both undergraduate and postgraduate learners, including procedural training, ventilator management guidance, complex communication scenarios, and didactic lectures on dynamic topics like multi-system organ failure. However, certain challenges are inherent in this setting that can make teaching difficult. Different trainee educational backgrounds, variability in disease states, time limitations and urgent patient care considerations highlight some challenges that limit teaching opportunities. The following twelve tips address these unique aspects of the ICU environment and provide strategies to optimize teaching. These tips focus on three main goals: creating an optimal learning environment, increasing learner engagement, and critically challenging learners.

Resolving Family-Clinician Disputes in the Context of Contested Definitions of Futility.

The word futile has been a touchstone in debates regarding resolution of disputes regarding life-prolonging treatments since the 1980s. Here, we respond to several criticisms of the Multiorganization Policy Statement, "An Official ATS/AACN/ACCP/ESICM/SCCM Policy Statement: Responding to Requests for Potentially Inappropriate Treatments in Intensive Care Units" (Bosslet et al. 2015). This response highlights the need for a strict definition of the word futile in order to avoid undue treatment differences when end-of-life interventions are contested. We also reply to several criticisms of this policy statement that are formulated upon fundamental misunderstandings of the statement and its assertions.

How Surrogates Decide: A Secondary Data Analysis of Decision-Making Principles Used by the Surrogates of Hospitalized Older Adults.

BACKGROUND: Many hospitalized adults do not have the capacity to make their own health care decisions and thus require a surrogate decision-maker. While the ethical standard suggests that decisions should focus on a patient's preferences, our study explores the principles that surrogates consider most important when making decisions for older hospitalized patients. OBJECTIVES: We sought to determine how frequently surrogate decision-makers prioritized patient preferences in decision-making and what factors may predict their doing so. DESIGN AND PARTICIPANTS: We performed a secondary data analysis of a study conducted at three local hospitals that surveyed surrogate decision-makers for hospitalized patients 65 years of age and older. MAIN MEASURES: Surrogates rated the importance of 16 decision-making principles and selected the one that was most important. We divided the surrogates into two groups: those who prioritized patient preferences and those who prioritized patient well-being. We analyzed the two groups for differences in knowledge of patient preferences, presence of advance directives, and psychological outcomes. KEY RESULTS: A total of 362 surrogates rated an average of six principles as being extremely important in decision-making; 77.8% of surrogates selected a patient well-being principle as the most important, whereas only 21.1% selected a patient preferences principle. Advance directives were more common to the patient preferences group than the patient well-being group (61.3% vs. 44.9%; 95% CI: 1.01-3.18; p = 0.04), whereas having conversations with the patient about their health care preferences was not a significant predictor of surrogate group identity (81.3% vs. 67.4%; 95% CI: 0.39-1.14; p = 0.14). We found no differences between the two groups regarding surrogate anxiety, depression, or decisional conflict. CONCLUSIONS: While surrogates considered many factors, they focused more often on patient well-being than on patient preferences, in contravention of our current ethical framework. Surrogates more commonly prioritized patient preferences if they had advance directives available to them.

Twelve tips for just in time teaching of communication skills for difficult conversations in the clinical setting.

The ability to communicate well with patients and other members of the healthcare team is a vital skill for physicians to have, but one that is often not emphasized in medical education. Learners of all levels can obtain and develop good communication skills regardless of their natural ability in this area, and the clinical setting represents an underutilized resource to accomplish this task. With this in mind, we have reviewed the growing body of literature on the subject and organized our findings into twelve tips to help educators capitalize on these missed opportunities. While our emphasis is helping learners with difficult discussions, these tips can be easily adapted to any other clinical encounter requiring clear communication. Teaching effective communication skills in the clinical setting requires some extra time, but the steps outlined should not take more than a few minutes to complete. Taking the time to develop these skills in our learners will make a significant difference not only their lives but also their patients and their families.

Smoking-Related Home Oxygen Burn Injuries: Continued Cause for Alarm.

BACKGROUND: Home oxygen therapy is a mainstay of treatment for patients with various cardiopulmonary diseases. In spite of warnings against smoking while using home oxygen, many patients sustain burn injuries. OBJECTIVES: We aimed to quantify the morbidity and mortality of such patients admitted to our regional burn unit over a 6-year period. METHODS: A retrospective chart review of all patients admitted to a regional burn center from 2008 through 2013 was completed. Admitted patients sustaining burns secondary to smoking while using home oxygen therapy were selected as the study population to determine morbidity. RESULTS: Fifty-five subjects were admitted to the burn unit for smoking-related home oxygen injuries. The age range was 40-84 years. Almost all subjects were on home oxygen for chronic obstructive pulmonary disease (96%). Seventy-two percent of burns involved <5% of the total body surface area, 51% of patients were intubated, and of those 33% had evidence of inhalation injury. The hospital mortality rate was 14.5%. The mean length of hospital stay was 8.6 days, and 54.5% were discharged to a nursing home or another advanced facility. Finally, concomitant substance abuse was found in 27%, and a previous history of injury from smoking while on home oxygen was discovered in 14.5%. CONCLUSIONS: This single-center analysis is one of the largest describing burn injuries stemming from smoking while using home oxygen therapy. We identified the morbidity and mortality associated with these injuries. Ongoing education and careful consideration of prescribing home oxygen therapy for known smokers is highly encouraged.

An Official ATS/AACN/ACCP/ESICM/SCCM Policy Statement: Responding to Requests for Potentially Inappropriate Treatments in Intensive Care Units.

BACKGROUND: There is controversy about how to manage requests by patients or surrogates for treatments that clinicians believe should not be administered. PURPOSE: This multisociety statement provides recommendations to prevent and manage intractable disagreements about the use of such treatments in intensive care units. METHODS: The recommendations were developed using an iterative consensus process, including expert committee development and peer review by designated committees of each of the participating professional societies (American Thoracic Society, American Association for Critical Care Nurses, American College of Chest Physicians, European Society for Intensive Care Medicine, and Society of Critical Care). MAIN RESULTS: The committee recommends: (1) Institutions should implement strategies to prevent intractable treatment conflicts, including proactive communication and early involvement of expert consultants. (2) The term "potentially inappropriate" should be used, rather than futile, to describe treatments that have at least some chance of accomplishing the effect sought by the patient, but clinicians believe that competing ethical considerations justify not providing them. Clinicians should explain and advocate for the treatment plan they believe is appropriate. Conflicts regarding potentially inappropriate treatments that remain intractable despite intensive communication and negotiation should be managed by a fair process of conflict resolution; this process should include hospital review, attempts to find a willing provider at another institution, and opportunity for external review of decisions. When time pressures make it infeasible to complete all steps of the conflict-resolution process and clinicians have a high degree of certainty that the requested treatment is outside accepted practice, they should seek procedural oversight to the extent allowed by the clinical situation and need not provide the requested treatment. (3) Use of the term "futile" should be restricted to the rare situations in which surrogates request interventions that simply cannot accomplish their intended physiologic goal. Clinicians should not provide futile interventions. (4) The medical profession should lead public engagement efforts and advocate for policies and legislation about when life-prolonging technologies should not be used. CONCLUSIONS: The multisociety statement on responding to requests for potentially inappropriate treatments in intensive care units provides guidance for clinicians to prevent and manage disputes in patients with advanced critical illness.

Variable Practice, Variable Results: Impact of Postinterview Communication Practices Among Critical Care Medicine/Pulmonary and Critical Care Medicine Fellowship Applicants and Program Directors.

BACKGROUND: Although postinterview communication (PIC) guidelines exist, adherence is voluntary. There are no studies of PIC practices in critical care medicine (CCM) and pulmonary and critical care medicine (PCCM) fellowship recruitment. RESEARCH QUESTION: What is the frequency, format, goals, and content of PIC between CCM/PCCM applicants and program directors? What is the impact of PIC on applicant and program rank order lists (ROLs)? STUDY DESIGN AND METHODS: CCM/PCCM applicants and program directors were separately surveyed after the 2022-2023 National Resident Matching Program Specialty Match. Surveys included multiple-choice, Likert-scale, and two free text questions. Thematic content analysis of free text responses was performed. RESULTS: One-third of eligible participants responded (applicants: n = 373 [34%]; program directors: n = 86 [32%]). Applicant respondents applied to CCM (19%), PCCM (69%), or both (12%). Program directors represented CCM (17%), PCCM (57%), or both (26%) programs. Applicant (66%) and program director (49%) respondents reported initiating PIC. PIC did not impact ROL decision for most applicants (73%) or program directors (83%), though 21% of applicants and 17% of program directors moved programs or applicants up on their ROL in response to PIC. One-quarter (23%) of applicants strongly agreed or agreed that PIC was helpful in creating their ROL, 27% strongly disagreed or disagreed, and 29% were neutral. PIC challenges identified by both groups included time; lack of uniformity; peer pressure; misleading language; and uncertainty about motives, rules, and response protocols. INTERPRETATION: PIC is common among CCM/PCCM applicants and program directors. About 50% of applicants and 20% of program directors share ranking intentions via PIC. Although PIC did not impact ROL for most applicants and program directors, a minority of applicants and program directors moved programs up on their ROL after receiving PIC from the other party. Applicants have mixed perspectives on PIC value. Applicants and program directors alike desire clear guidance on PIC to minimize ambiguous and misleading communication.

The Virtual Interview Experience: Perspectives of Pulmonary and Critical Care Fellowship Applicants.

Background: Because of the coronavirus disease (COVID-19) pandemic, graduate medical education programs adopted virtual interviews (VIs) as the default modality for the 2020 recruitment season. It is unknown whether VIs allowed applicants to effectively evaluate programs, and the best interview format for the future is unclear. Objective: To 1) assess pulmonary and critical care applicants' perceived ability to evaluate programs using VIs, 2) determine the attitudes of applicants toward the components of VIs, and 3) identify applicants' preferences for the future fellowship interview format. Methods: After the National Residency Matching Program medical subspecialty match, an electronic survey was sent to 1,067 applicants to pulmonary and critical care medicine programs asking them to compare their fellowship VI experience with their residency in-person interview (IPI) experience. Results: Three hundred six (29%) applicants responded to the survey, and 289 completed it (27%). There were 117 (40%) women and 146 (51%) White individuals. Most respondents believed that VIs hindered their ability to evaluate programs' culture, faculty-fellow relationships, location, facilities, and their own fit within the program. They believed they were able to evaluate the clinical experience, curriculum, and potential for academic development equally well compared with IPIs. The most helpful elements of VIs were the interview with the program director, meetings with the fellows, and interviews with faculty members. Less helpful elements included conference access, prerecorded program director presentations, virtual hospital and city tours, and video testimonials. One hundred twenty-three respondents (43%) chose VIs with an optional visit as their preferred future interview format, 85 (29%) chose IPIs, 54 (19%) wanted a choice between VIs and IPIs, and 27 (9%) chose VIs only. Conclusion: Most pulmonary and critical care medicine applicants preferred future interviews to include both VIs and the option of an in-person visit or interview. This study can assist programs in designing their future interview formats in a trainee-centric fashion.

The patient-doctor relationship and online social networks: results of a national survey.

BACKGROUND: The use of online social networks (OSNs) among physicians and physicians-in-training, the extent of patient-doctor interactions within OSNs, and attitudes among these groups toward use of OSNs is not well described. OBJECTIVE: To quantify the use of OSNs, patient interactions within OSNs, and attitudes toward OSNs among medical students (MS), resident physicians (RP), and practicing physicians (PP) in the United States. DESIGN/SETTING: A random, stratified mail survey was sent to 1004 MS, 1004 RP, and 1004 PP between February and May 2010. MEASUREMENTS: Percentage of respondents reporting OSN use, the nature and frequency of use; percentage of respondents reporting friend requests by patients or patients' family members, frequency of these requests, and whether or not they were accepted; attitudes toward physician use of OSNs and online patient interactions. RESULTS: The overall response rate was 16.0% (19.8% MS, 14.3% RP, 14.1% PP). 93.5% of MS, 79.4% of RP, and 41.6% of PP reported usage of OSNs. PP were more likely to report having visited the profile of a patient or patient's family member (MS 2.3%, RP 3.9%, PP 15.5%), and were more likely to have received friend requests from patients or their family members (MS 1.2%, RP 7.8%, PP 34.5%). A majority did not think it ethically acceptable to interact with patients within OSNs for either social (68.3%) or patient-care (68.0%) reasons. Almost half of respondents (48.7%) were pessimistic about the potential for OSNs to improve patient-doctor communication, and a majority (79%) expressed concerns about maintaining patient confidentiality. CONCLUSION: Personal OSN use among physicians and physicians-in-training mirrors that of the general population. Patient-doctor interactions take place within OSNs, and are more typically initiated by patients than by physicians or physicians-in-training. A majority of respondents view these online interactions as ethically problematic.

Parental procreative obligation and the categorisation of disease: the case of cystic fibrosis.

The advent of prenatal genetic diagnosis has sparked debates among ethicists and philosophers regarding parental responsibility towards potential offspring. Some have attempted to place moral obligations on parents to not bring about children with certain diseases in order to prevent harm to such children. There has been no rigorous evaluation of cystic fibrosis in this context. This paper will demonstrate cystic fibrosis to have unique properties that make it difficult to categorize among other diseases with the goal of promulgating a reproductive rule. Once this is established, it will be demonstrated that procreative rules that appeal to future health are inadequate in the era of advancing genetic knowledge. Utilising a specification of Joel Feinberg's 'open future' concept outlined by Matteo Mameli, it will offer an analysis of parental obligation that does not constrain parents of potential children with cystic fibrosis with a moral obligation not to bring them about.

Project management tools for healthcare education.

Health care education inherently requires managing projects, but few educators have the luxury of working with a project manager. In this article, we propose that applying project management theory to education work, and using project management software to organize our work, can improve our efficiency. We outline the approach project managers take to their work, which includes five steps: initiating, planning, executing, monitoring and controlling, and closing. We apply project management theory to the processes involved with health care education projects, and we describe the typical work that would be done at each step. We introduce readers to project management software, using one free program as an example. We provide examples of how we have used the software successfully. Finally, we provide suggestions for educators to use when selecting project management software.

Balancing Demands: Determinants of Burnout Reported by Fellows in Pulmonary and Critical Care Medicine.

Background: Burnout is common among physicians who care for critically ill patients and is known to contribute to worse patient outcomes. Fellows training in pulmonary and critical care medicine (PCCM) have risk factors that make them susceptible to burnout; for example, clinical environments that require increased intellectual and emotional demands with long hours. The Accreditation Council for Graduate Medical Education has recognized the increasing importance of trainee burnout and encourages training programs to address burnout. Objective: To assess factors related to training and practice that posed a threat to the well-being among fellows training in PCCM and to obtain suggestions regarding how programs can improve fellow well-being. Methods: We conducted a qualitative content analysis of data collected from a prior cross-sectional electronic survey with free-response questions of fellows enrolled in pulmonary, PCCM, and critical care medicine training programs in the United States. Fellows were asked what factors posed a threat to their well-being and what changes their training program could implement. Responses were qualitatively coded and categorized into themes using thematic analysis. Results: A total of 427 fellows (44% of survey respondents) completed at least one free-response question. The majority of respondents (60%) identified as male and white/non-Hispanic (59%). The threats to well-being and burnout were grouped into five themes: clinical burden, individual factors, team culture, limited autonomy, and program resources. Clinical burden was the most common threat discussed by fellows. Fellows highlighted factors contributing to burnout that specifically pertained to trainees including challenging interpersonal relationships with attending physicians and limited protected educational time. Fellows proposed solutions addressing clinical care, changes at the program or institution level, and organizational culture changes to improve well-being. Conclusion: This study provides insight into factors fellows report as contributors to burnout and decreased well-being in addition to investigating fellow-driven solutions toward improving well-being. These solutions may help pulmonary, PCCM, and critical care medicine program directors better address fellow well-being in the future.

A National Survey of Burnout and Depression Among Fellows Training in Pulmonary and Critical Care Medicine: A Special Report by the Association of Pulmonary and Critical Care Medicine Program Directors.

BACKGROUND: The prevalence of burnout and depressive symptoms is high among physician trainees. RESEARCH QUESTION: What is the burden of burnout and depressive symptoms among fellows training in pulmonary and critical care medicine (PCCM) and what are associated individual fellow, program, and institutional characteristics? STUDY DESIGN AND METHODS: We conducted a cross-sectional electronic survey of fellows enrolled in pulmonary, PCCM, and critical care medicine training programs in the United States to assess burnout and depressive symptoms. Burnout symptoms were measured using the Maslach Burnout Index two-item measure. The two-item Primary Care Evaluation of Mental Disorders Procedure was used to screen for depressive symptoms. For each of the two outcomes (burnout and depressive symptoms), we constructed three multivariate logistic regression models to assess individual fellow characteristics, program structure, and institutional polices associated with either burnout or depressive symptoms. RESULTS: Five hundred two of the 976 fellows who received the survey completed it-including both outcome measures-giving a response rate of 51%. Fifty percent of fellows showed positive results for either burnout or depressive symptoms, with 41% showing positive results for depressive symptoms, 32% showing positive results for burnout, and 23% showing positive results for both. Reporting a coverage system in the case of personal illness or emergency (adjusted OR [aOR], 0.44; 95% CI, 0.26-0.73) and access to mental health services (aOR, 0.14; 95% CI, 0.04-0.47) were associated with lower odds of burnout. Financial concern was associated with higher odds of depressive symptoms (aOR, 1.13; 95% CI, 1.05-1.22). Working more than 70 hours in an average clinical week and the burdens of electronic health record (EHR) documentation were associated with a higher odds of both burnout and depressive symptoms. INTERPRETATION: Given the high prevalence of burnout and depressive symptoms among fellows training in PCCM, an urgent need exists to identify solutions that address this public health crisis. Strategies such as providing an easily accessible coverage system, access to mental health resources, reducing EHR burden, addressing work hours, and addressing financial concerns among trainees may help to reduce burnout or depressive symptoms and should be studied further by the graduate medical education community.

Nurse-administered propofol sedation: feasibility and safety in bronchoscopy.

BACKGROUND: Propofol is a fast-acting intravenous sedative that has advantages as a procedural sedative over traditional regimens. It has been shown to have a similar safety profile to traditional sedating medications in the setting of gastroenterologic endoscopy. Nurse-administered propofol sedation is given by a specially-trained nurse, without anesthesiologist involvement. OBJECTIVES: We have used nurse-administered propofol sedation in our bronchoscopy suite for several years. In this report, we summarize our experience with nurse-administered propofol sedation, and demonstrate it to be feasible and safe for bronchoscopic procedures. METHODS: Procedure reports and nursing notes for 588 bronchoscopic procedures performed between July 2006 and June 2008 were retrospectively reviewed. Patient demographics, procedure type and indication, procedure time, medication doses, and adverse events were noted and analyzed. RESULTS: Nurse-administered propofol sedation was used in 498/588 (85%) procedures. Patients utilizing nurse-administered propofol sedation had an average age of 53 years (range 18-86) with an average weight of 80 kg. 56% of the patients were male, and 57% of the procedures were performed on outpatients. Average procedure duration was 25 min (range 3-123). The average propofol dose was 3.13 mg/kg (range 0.12-20 mg/kg). Adverse events attributable to sedation were noted in 33 (6.6%) procedures. Of the 14 (2.8%) major adverse events (death, need for intubation, ICU stay, or hospitalization), only 6 (1.2%) were potentially attributable to the sedation regimen. There were 2 deaths, neither of which was related to sedation. CONCLUSIONS: Nurse-administered propofol sedation is a feasible and safe sedation method for bronchoscopic procedures.

Social complexity negatively influences lung function in cystic fibrosis after transfer to adult care.

BACKGROUND: Several nongenetic factors, such as socioeconomic status, environmental exposures, and adherence have been described to have an impact on outcomes in cystic fibrosis (CF). OBJECTIVE: To determine the effect of social complexity on the % predicted forced expiratory volume (ppFEV1 ) before and after transfer to adult care among adolescents with CF. METHODS: Retrospective, single center, cohort study included all patients with CF who were transitioned into adult care between 2005 and 2015 at Indiana University. Social complexity (Bob's level of social support, [BLSS]) was collected at transfer. Linear mixed regression models assessed the relationship between ppFEV1 decline over time and BLSS with other covariates. RESULTS: The median age of the patients (N = 133) at the time of transfer was 20 years (interquartile range: 19-23). Overall, there was a decline in lung function over time in our population (ppFEV1 at 24 months pretransfer 77 ± 20%, ppFEV1 at 24 months, posttransfer 66 ± 24%; P < .001). The relationship between BLSS and ppFEV1 became more negative over time, even after adjusting for other covariates. CONCLUSION: Social complexity is strongly associated with lung function decline after transfer to adult care.

What Do Program Directors Value in Personal Statements? A Qualitative Analysis.

Background: All applicants to accredited training programs must write a personal statement as part of the application process. This may provoke anxiety on the part of the applicant and can result in an impersonal product that does not enhance his or her application. Little has been written about what program directors are seeking in personal statements. Objective: To gain a better understanding of how pulmonary and critical care fellowship program directors view and interpret these essays and to help applicants create more effective personal statements and make the writing process less stressful. Methods: We surveyed the membership of the Association of Pulmonary and Critical Care Medicine Program Directors in 2018. Quantitative data were collected regarding the importance of the personal statement in the candidate selection process. Qualitative data exploring the characteristics of personal statements, what the personal statement reveals about applicants, and advice for writing them were also collected. Comparative analysis was used for coding and analysis of qualitative data. Results: Surveys were completed by 114 out of 344 possible respondents (33%). More than half of the respondents believed that the personal statement is at least moderately important when deciding to offer an interview, and 40% believed it is at least moderately important when deciding rank order. A qualitative analysis revealed consistent themes: communication skills, provision of information not found elsewhere, applicant characteristics, and things to avoid. Conclusion: The respondents view the personal statement as moderately important in the application process. They value succinct, quality writing that reveals personal details not noted elsewhere. The information presented may help reduce anxiety associated with writing the personal statement and result in making the personal statement a more meaningful part of the application.
